TI Oxygen Vacancies and Ordering of d-levels Control Voltage Suppression in Oxide Cathodes: the Case of Spinel LiNi0.5Mn1.5O4-delta SO ADVANCED FUNCTIONAL MATERIALS LA English DT Article DE structure-property relationships; spinel transition metal oxides; oxygen vacancies; energy storage ID LITHIUM-ION BATTERIES; AUGMENTED-WAVE METHOD; WIDE BAND-GAP; ELECTROCHEMICAL PROPERTIES; HIGH ELECTROCONDUCTIVITY; SITE DISORDER; LI; PERFORMANCE; INSERTION; ELECTRODES AB This study presents a microscopic model for the correlation between the concentration of oxygen vacancies and voltage suppression in high voltage spinel cathodes for Li-ion batteries. Using first principles simulations, it is shown that neutral oxygen vacancies in LiNi0.5Mn1.5O4- promote substitutional Ni/Mn disorder and the formation of Ni-rich and Ni-poor regions. The former trap oxygen vacancies, while the latter trap electrons associated with these vacancies. This leads to the creation of deep and shallow Mn3+ states and affects the stability of the lattice Li ions. Together, these two factors result in a characteristic profile of the voltage dependence on Li content. This insight provides guidance for mitigating the voltage suppression in LiNi0.5Mn1.5O4 and other cathodes. C1 [Sushko, Peter V.] UCL, Dept Phys & Astron, London WC1E 6BT, England.

TI New physics in B -> K*mu mu? SO EUROPEAN PHYSICAL JOURNAL C LA English DT Article ID K-ASTERISK-L(+)L(-) AB Recent experimental results on angular observables in the rare decay B -> K*mu(+)mu(-) show significant deviations from Standard Model predictions. We investigate the possibility that these deviations are due to new physics. Combining all relevant data on b -> s rare decays, we show that a consistent explanation of most anomalies can be obtained by new physics contributing simultaneously to the semi-leptonic vector operator O-9 and its chirality-flipped counterpart O-9'. A partial explanation is possible with new physics in O-9 or in dipole operators only. We study in detail the implications for models of new physics, in particular the minimal supersymmetric standard model, models with partial compositeness and generic models with flavour-changing Z' bosons. In all considered models, contributions to B -> K*mu(+)mu(-) of the preferred size imply a spectrum close to the TeV scale. We stress that measurements of CP asymmetries in B -> K*mu(+)mu(-) could provide valuable information to narrow down possible new physics explanations.

A similar to 10 angstrom thick film of amorphous material is observed to form immediately at the molecular monolayer, consistent with the proposed formation of "Posner clusters". This layer becomes denser but not significantly thicker as the subphase concentration and the temperature approach physiological conditions. The amorphous films do not crystallize within 24 h, in contrast to prior reports of more rapid crystallization using electron microscopy on ex situ samples. However, crystallization occurs almost immediately after our films are transferred onto solid substrates. These results illustrate the importance of in situ measurements for model biomineralization experiments.

TI Magnetic structure in the spin liquid Tb2Ti2O7 induced by a [111] magnetic field: Search for a magnetization plateau SO PHYSICAL REVIEW B LA English DT Article ID DIFFRACTION; ICE AB We have studied the field-induced magnetic structures of Tb2Ti2O7 pyrochlore by single-crystal neutron diffraction under a field applied along the [111] axis, up to H = 12 T and down to T = 40 mK. We refined the magnetic structures with k = 0 propagation vector by performing a symmetry analysis in the space group R3m, reducing the number of free parameters to three only. The Tb moments gradually reorient towards the field direction, keeping close to a "3-in, 1-out/1-in, 3-out"spin structure (magnetic space group R 3 m') in the whole measured field range 0.05-12 T. Our results rule out the "all-in/all-out"structure previously proposed and do not support the existence of a magnetization plateau. We perform a quantitative comparison with mean-field calculations and we propose the presence of a low-temperature dynamic symmetry breaking of the local trigonal symmetry, akin to a dynamic Jahn-Teller effect, i.e., preserving the overall cubic symmetry. We discuss the possible origin of this off-diagonalmixing term in the crystal field Hamiltonian in terms of quadrupole-quadrupole interaction or magnetoelastic effects. C1 [Sazonov, A.

CA CDF Collaboration TI Search for a dijet resonance in events with jets and missing transverse energy in p(p)over-bar collisions at root S 1: 96 TeV SO PHYSICAL REVIEW D LA English DT Article AB We report on a search for a dijet resonance in events with only two or three jets and a large imbalance in the total event transverse momentum. This search is sensitive to the possible production of a new particle in association with a W or Z boson, where the boson decays leptonically with one or more neutrinos in the final state. We use the full data set collected by the CDF II detector at the Tevatron collider at a protonantiproton center- of- mass energy of 1.96 TeV. These data correspond to an integrated luminosity of 9: 1 fb(-1). We study the invariant mass distribution of the two jets with highest transverse energy. We find good agreement between data and standard model background expectations and measure the combined cross section for WW, WZ, and ZZ production to be 13: 8+(3.0) (-2.7) pb. No significant anomalies are observed in the mass spectrum, and 95% credibility level upper limits are set on the production rates of a potential new particle in association with a W or Z boson.

CA CDF Collaboration TI Production of K-S(,)0 K-*+/- (892) and phi(0) (1020) in minimum bias events and K-S(0) and Lambda(0) in jets in p (p)over-barcollisions at root S 1: 96 TeV SO PHYSICAL REVIEW D LA English DT Article ID PROTON-ANTIPROTON COLLISIONS; STRANGE PARTICLE-PRODUCTION; DEEP-INELASTIC SCATTERING; GEV CM ENERGY; P(P)OVER-BAR COLLISIONS; E+E-ANNIHILATION; ELECTROMAGNETIC CALORIMETER; SQUARE-ROOT-S=1.8 TEV; INCLUSIVE PRODUCTION; PBARP INTERACTIONS AB We report measurements of the inclusive transverse momentum (p(T)) distribution of centrally produced K-S(0), K-*perpendicular to (892), and phi(0)(1020) mesons up to p(T) = 10 GeV/c in minimum bias events, and K-S(0) and Lambda(0) particles up to p(T) = 20 GeV/c in jets with transverse energy between 25 and 160 GeV in p (p) over bar collisions. The data were taken with the CDF II detector at the Fermilab Tevatron at root s = 1.96 TeV. We find that as p(T) increases, the p(T) slopes of the three mesons (K-S(0), K-*+/-, and phi) are similar. And using our previous Lambda(0) results from minimum bias events, we show that the ratio of Lambda(0) to K-S(0) as a function of p(T) in minimum bias events becomes similar to the fairly constant ratio in jets at p(T) similar to 5 GeV/c. This suggests that the particles with p(T) * 5 GeV/c in minimum bias events are from "soft'' jets, and that the p(T) slope of particles in jets is insensitive to light quark flavor (u, d, or s) and to the number of valence quarks. We also find that for p(T) & 4 GeV relatively more Lambda(0) baryons are produced in minimum bias events than in jets. C1 [Chen, Y. C.; Hou, S.; Mitra, A.; Teng, P. K.; Wang, S.

CA SCENE Collaboration TI Observation of the dependence on drift field of scintillation from nuclear recoils in liquid argon SO PHYSICAL REVIEW D LA English DT Article ID XENON; EFFICIENCY; LUMINESCENCE; ENERGY; YIELD AB We have exposed a dual-phase liquid argon time projection chamber (LAr-TPC) to a low energy pulsed narrow-band neutron beam, produced at the Notre Dame Institute for Structure and Nuclear Astrophysics, to study the scintillation light yield of recoiling nuclei. Liquid scintillation counters were arranged to detect and identify neutrons scattered in the LAr-TPC and to select the energy of the recoiling nuclei. We report the observation of a significant dependence (up to 32%) on the drift field of liquid argon scintillation from nuclear recoils of energies between 10.8 and 49.9 keV. The field dependence is stronger at lower energies. Since it is the first measurement of such an effect in liquid argon, this observation is important because, to date, estimates of the sensitivity of LAr-TPC dark matter searches are based on the assumption that the electric field has only a small effect on the light yield from nuclear recoils.

TI Quark number susceptibilities at high temperatures SO PHYSICAL REVIEW D LA English DT Article ID QCD TRANSITION; THERMODYNAMICS; LATTICE; SIMULATIONS; FERMIONS; SCALE AB We calculate second and fourth order quark number susceptibilities for 2+1 flavor QCD in the high temperature region. In our study, we use two improved staggered fermion formulations, namely, the highly improved staggered quark formulation and the so-called p4 formulation, as well as several lattice spacings. Second order quark number susceptibilities are calculated using both improved staggered fermion formulations, and we show that in the continuum limit the two formulations give consistent results. The fourth order quark number susceptibilities are studied only using the p4 formulation and at nonzero lattice spacings. We compare our results on quark number susceptibilities with recent weak coupling calculations and find that these agree reasonably well with the lattice calculations within the estimated uncertainties.

TI D-s0*(2317) Meson and D-Meson-Kaon Scattering from Lattice QCD SO PHYSICAL REVIEW LETTERS LA English DT Article ID QUANTUM-FIELD THEORIES; GAUGE-THEORY; SPECTROSCOPY; MATRIX; STATES AB The scalar meson D-s0*(2317) is found 37(17) MeV below the DK threshold in a lattice simulation of the J(P)= 0(+) channel using, for the first time, both DK as well as (s) over bar c interpolating fields. The simulation is done on N-f = 2 + 1 gauge configurations with m(pi) similar or equal to 156 MeV, and the resulting M-Ds0* - 1/4(MDs + 3M(Ds)*) = 266(16) MeV is close to the experimental value 241: 5(0.8) MeV. The energy level related to the scalar meson is accompanied by additional discrete levels due toDK scattering states. The levels near threshold lead to the negativeDK scattering length a(0) = 1. 33(20) fm that indicates the presence of a state belowthreshold.

TI Nematic-Field-Driven Positioning of Particles in Liquid Crystal Droplets SO PHYSICAL REVIEW LETTERS LA English DT Article ID SIMULATION; SIZE AB Common nematic oils, such as 5CB, experience planar anchoring at aqueous interfaces. When these oils are emulsified, this anchoring preference and the resulting topological constraints lead to the formation of droplets that exhibit one or two point defects within the nematic phase. Here, we explore the interactions of adsorbed particles at the aqueous interface through a combination of experiments and coarse-grained modeling, and demonstrate that surface-active particles, driven by elastic forces in the droplet, readily localize to these defect regions in a programmable manner. When droplets include two nanoparticles, these preferentially segregate to the two poles, thereby forming highly regular dipolar structures that could serve for hierarchical assembly of functional structures. Addition of sufficient concentrations of surfactant changes the interior morphology of the droplet, but pins defects to the interface, resulting in aggregation of the two particles.

TI High Pressure as a Key Factor to Identify the Conductivity Mechanism in Protic Ionic Liquids SO PHYSICAL REVIEW LETTERS LA English DT Article ID PHYSICOCHEMICAL PROPERTIES; RELAXATION; TRANSPORT; DYNAMICS; ACIDS AB In this Letter we report the relation between ionic conductivity and structural relaxation in supercooled protic ionic liquids (PILs) under high pressure. The results of high-pressure dielectric and volumetric measurements, combined with rheological and temperature-modulated differential scanning calorimetry experiments, have revealed a fundamental difference between the conducting properties under isothermal and isobaric conditions for three PILs with different charge transport mechanisms (Grotthuss vs vehicle). Our findings indicate a breakdown of the fractional Stokes-Einstein relation and Walden rule when the ionic transport is controlled by fast proton hopping. Consequently, we demonstrate that the studied PILs exhibit significantly higher conductivity than one would expect taking into account that they are in fact a mixture of ionic and neutral species. Thus, the examined herein samples represent a new class of "superionic'' materials desired for many advanced applications.

The six-armed star architectures are composed of stacked nanosheets homoepitaxially oriented along the [100] crystallographic register with respect to one another, as confirmed by means of selected area electron diffraction and electron microscopy. It is proposed that the mesocrystal formation mechanism proceeds through classical as well as non-classical crystallization processes, and is possibly facilitated or promoted by the presence of a reducing/chelating agent. The synthesized VO2(B) mesocrystals are tested as a cathodic electrode material for lithium-ion batteries, and show good capacity at discharge rates ranging from 150-1500 mA g(-1) and a cyclic stability of 195 mA h g(-1) over fifty cycles. The superb electrochemical performance of the VO2(B) mesocrystals is attributed to the porous and oriented superstructure that ensures large surface area for redox reaction and short diffusion distances. The mesocrystalline structure ensures that all the surfaces are in intimate contact with the electrolyte, and that lithium-ion intercalation occurs uniformly throughout the entire electrode. The exposed (100) facets also lead to fast lithium intercalation, and the homoepitaxial stacking of nanosheets offers a strong inner-sheet binding force that leads to better accommodation of the strain induced during cycling, thus circumventing the capacity fading issues typically associated with VO2(B) electrodes.

From an industrial perspective, these oxide layers are particularly interesting for use as unique authenticity identifiers on welded or sealed components. Processing parameters control oxide thickness and residual stresses. The combined properties of the oxide-substrate system control deformation, fracture, and electromechanical behavior. Instrumented nanoindentation indicates that oxide mechanical properties are dictated by film thickness. While elastic modulus is relatively insensitive to laser processing conditions and has an average value of similar to 150 GPa, hardness decreases sharply as film thickness decreases below 100 nm. Indentation coupled with electron microscopy as well as conducting nanoindentation suggest that both fracture behavior and electromechanical response are a function of laser processing; thick oxides fracture circumferentially upon indentation while thin oxides undergo radial cracking and thinner laser oxides are typically more conductive than their thicker counterparts.

Previous work in Shewanella oneidensis MR-1 has indicated that some genes within a cluster (mtrBAC-omcA-mtrFED) were involved in iron reduction. To explore new features of iron reduction pathways, we experimentally analyzed Shewanella putrefaciens W3-18-1 since its gene cluster is considerably different from that of MR-1 in that the gene cluster encodes only four ORFs. Results: Among the gene cluster, two genes (mtrC and undA) were shown to encode c-type cytochromes. The Delta mtrC deletion mutant revealed significant deficiencies in reducing metals of Fe2O3, a-FeO(OH), beta-FeO(OH), ferric citrate, Mn (IV) and Co(III), but not organic compounds. In contrast, no deficiency of metal reduction was observed in the Delta undA deletion mutant. Nonetheless, undA deletion resulted in progressively slower iron reduction in the absence of mtrC and fitness loss under the iron-using condition, which was indicative of a functional role of UndA in iron reduction. Conclusions: These results provide physiological and biochemical evidences that UndA and MtrC of Shewanella putrefaciens W3-18-1 are involved in iron reduction.

CA ATLAS Collaboration TI Measurement of the distributions of event-by-event flow harmonics in lead-lead collisions at root s(NN)=2.76 TeV with the ATLAS detector at the LHC SO JOURNAL OF HIGH ENERGY PHYSICS LA English DT Article DE Heavy-ion collision; harmonic flow; event-by-event fluctuation; unfolding; Hadron-Hadron Scattering ID RELATIVISTIC NUCLEAR COLLISIONS; ELLIPTIC FLOW; ECCENTRICITY FLUCTUATIONS; TRANSVERSE-MOMENTUM; ANISOTROPIC FLOW AB The distributions of event-by-event harmonic flow coefficients v (n) for n = 2- 4 are measured in = 2.76 TeV Pb + Pb collisions using the ATLAS detector at the LHC. The measurements are performed using charged particles with transverse momentum p (T) > 0.5 GeV and in the pseudorapidity range |eta| < 2.5 in a dataset of approximately 7 mu b(-1) recorded in 2010. The shapes of the v (n) distributions suggest that the associated flow vectors are described by a two-dimensional Gaussian function in central collisions for v (2) and over most of the measured centrality range for v (3) and v (4). Significant deviations from this function are observed for v (2) in mid-central and peripheral collisions, and a small deviation is observed for v (3) in mid-central collisions. In order to be sensitive to these deviations, it is shown that the commonly used multi-particle cumulants, involving four particles or more, need to be measured with a precision better than a few percent. The v (n) distributions are also measured independently for charged particles with 0.5 < p (T) < 1 GeV and p (T) > 1 GeV. When these distributions are rescaled to the same mean values, the adjusted shapes are found to be nearly the same for these two p (T) ranges. The v (n) distributions are compared with the eccentricity distributions from two models for the initial collision geometry: a Glauber model and a model that includes corrections to the initial geometry due to gluon saturation effects. Both models fail to describe the experimental data consistently over most of the measured centrality range. C1 [Jackson, P.; Soni, N.] Univ Adelaide, Sch Chem & Phys, Adelaide, SA, Australia.

CA ALICE Collaboration TI K-S(0) and Lambda Production in Pb-Pb Collisions at root s(NN)=2: 76 TeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID QUARK-GLUON PLASMA; PARTICLE-PRODUCTION; ENERGY; LHC AB The ALICE measurement of K-S(0) and Lambda production at midrapidity in Pb-Pb collisions at root sNN = 2.76 TeV is presented. The transverse momentum (p(T)) spectra are shown for several collision centrality intervals and in the p(T) range from 0: 4 GeV/c (0: 6 GeV/c for Lambda) to 12 GeV/c. The p(T) dependence of the Lambda/K-S(0) ratios exhibits maxima in the vicinity of 3 GeV/c, and the positions of the maxima shift towards higher p(T) with increasing collision centrality. The magnitude of these maxima increases by almost a factor of three between most peripheral and most central Pb-Pb collisions. This baryon excess at intermediate p(T) is not observed in pp interactions at root s = 0.9 TeV and at root s = 7 TeV. Qualitatively, the baryon enhancement in heavy-ion collisions is expected from radial flow. However, the measured p(T) spectra above 2 GeV/c progressively decouple from hydrodynamical-model calculations. For higher values of p(T), models that incorporate the influence of the medium on the fragmentation and hadronization processes describe qualitatively the p(T) dependence of the Lambda/K-S(0) ratio.

CA CMS Collaboration TI Search for Top Squarks in R-Parity-Violating Supersymmetry Using Three or More Leptons and b-Tagged Jets SO PHYSICAL REVIEW LETTERS LA English DT Article ID E(+)E(-) COLLISIONS; STANDARD MODEL; PP COLLISIONS; PARTICLES; PHYSICS; TEV; DECAYS; STATES; BOSON; HERA AB A search for anomalous production of events with three or more isolated leptons and bottom-quark jets produced in pp collisions at root s = 8 TeV is presented. The analysis is based on a data sample corresponding to an integrated luminosity of 19: 5 fb(-1) collected by the CMS experiment at the LHC in 2012. No excess above the standard model expectations is observed. The results are interpreted in the context of supersymmetric models with signatures that have low missing transverse energy arising from light top-squark pair production with R-parity-violating decays of the lightest supersymmetric particle. In two models with different R-parity-violating couplings, top squarks are excluded below masses of 1020 GeV and 820 GeV when the lightest supersymmetric particle has a mass of 200 GeV.

In this study, P3HT:PCBM blend is deposited onto hydrophilic and hydrophobic substrate to examine the film stratifications. The neutron reflectivity results show that, on the different surfaces, PCBM diffuses toward the two interfacial regions in an identical fashion during thermal annealing. This evidences that the film stratification is not affected by the substrates. Instead, since P3HT remains more amorphous in the interfacial regions and PCBM is miscible with amorphous P3HT, PCBM preferentially diffuses to the interfacial regions, resulting in the stratification.

In this work, multiwalled carbon nanotubes (CNTs) were incorporated into polycrystalline Bi0.4Sb1.6Te3 through powder processing, which increased the flexural strength from 32 MPa to 90MPa. Electrical and thermal conductivities were both reduced in the CNT containing materials, leading to unchanged figure of merit. Dynamic Young's and shear moduli of the composites were lower than the base material, while the Poisson's ratio was not affected by CNT doping. (C) 2013 AIP Publishing LLC.

TI An Integrated Model of Environmental Effects on Growth, Carbohydrate Balance, and Mortality of Pinus ponderosa Forests in the Southern Rocky Mountains SO PLOS ONE LA English DT Article ID INDUCED TREE MORTALITY; CHANGE-TYPE DROUGHT; CLIMATE-CHANGE; DIE-OFF; UNITED-STATES; VEGETATION MORTALITY; TROPICAL FOREST; CARBON; MECHANISMS; WATER AB Climate-induced tree mortality is an increasing concern for forest managers around the world. We used a coupled hydrologic and ecosystem carbon cycling model to assess temperature and precipitation impacts on productivity and survival of ponderosa pine (Pinus ponderosa). Model predictions were evaluated using observations of productivity and survival for three ponderosa pine stands located across an 800 m elevation gradient in the southern Rocky Mountains, USA, during a 10-year period that ended in a severe drought and extensive tree mortality at the lowest elevation site. We demonstrate the utility of a relatively simple representation of declines in non-structural carbohydrate (NSC) as an approach for estimating patterns of ponderosa pine vulnerability to drought and the likelihood of survival along an elevation gradient. We assess the sensitivity of simulated net primary production, NSC storage dynamics, and mortality to site climate and soil characteristics as well as uncertainty in the allocation of carbon to the NSC pool. For a fairly wide set of assumptions, the model estimates captured elevational gradients and temporal patterns in growth and biomass. Model results that best predict mortality risk also yield productivity, leaf area, and biomass estimates that are qualitatively consistent with observations across the sites. Using this constrained set of parameters, we found that productivity and likelihood of survival were equally dependent on elevation-driven variation in temperature and precipitation. Our results demonstrate the potential for a coupled hydrology-ecosystem carbon cycling model that includes a simple model of NSC dynamics to predict drought-related mortality. Given that increases in temperature and in the frequency and severity of drought are predicted for a broad range of ponderosa pine and other western North America conifer forest habitats, the model potentially has broad utility for assessing ecosystem vulnerabilities.

These variations in these key material properties of nanoparticles may affect their environmental fate and transport. To date, few studies have investigated this important aspect of nanoparticles' environmental behavior. In this study, the aggregation kinetics of ten different TiO2 nanoparticles (5 anatase and 5 rutile each with varying size) was systematically evaluated. Our results show that, as particle size increases, the surface charge of both anatase and rutile TiO2 nanoparticles shifts toward a more negative value, and, accordingly, the point of zero charge shifts toward a lower value. The colloidal stability of anatase sphere samples agreed well with DLVO theoretical predictions, where an increase in particle size led to a higher energy barrier and therefore greater critical coagulation concentration. In contrast, the critical coagulation concentration of rutile rod samples correlated positively with the specific surface area, i.e., samples with higher specific surface area exhibited higher stability. Finally, due to the large innate negative surface charge of all the TiO2 samples at the pH value (pH = 8) tested, the addition of natural organic matter was observed to have minimal effect on TiO2 aggregation kinetics, except for the smallest rutile rods that showed decreased stability in the presence of natural organic matter.

In addition, Breit-Pauli R-matrix calculations have been carried out in the region of the 2p thresholds, and the results are compared with experiment. Owing to angular-momentum considerations, it was found that the resonances associated with the higher 2p(-1) thresholds should be significantly wider than the lower ones, and this is borne out in both the experimental and the theoretical results. It is shown that a large number of resonance series contribute to the cross section, which make it difficult to untangle, and suggestions for further work to better understand the spectra are presented.

An underlying core-shell structure consistent with remnants of a high-density liquid structure was revealed by small-angle x-ray scattering and molecular dynamics simulations. Ion track dimensions differ for as-implanted and relaxed Si as attributed to different microstructures and melting temperatures. The identification and characterization of ion tracks in amorphous Si yields new insight into mechanisms of damage formation due to swift heavy-ion irradiation in amorphous semiconductors.

TI Local structural evidence for strong electronic correlations in spinel LiRh2O4 SO PHYSICAL REVIEW B LA English DT Article ID TRANSITION; MANGANITES; CUIR2S4 AB The local structure of the spinel LiRh2O4 has been studied using atomic-pair distribution function analysis of powder x-ray diffraction data. This measurement is sensitive to the presence of short Rh-Rh bonds that form due to dimerization of Rh4+ ions on the pyrochlore sublattice, independent of the existence of long-range order. We show that structural dimers exist in the low-temperature phase, as previously supposed, with a bond shortening of Delta r similar to 0.15 angstrom. The dimers persist up to 350 K, well above the insulator-metal transition, with Delta r decreasing in magnitude on warming. Such behavior is inconsistent with the Fermi-surface nesting-driven Peierls transition model. Instead, we argue that LiRh2O4 should properly be described as a strongly correlated system. C1 [Knox, K.

TI Adiabatic release measurements in alpha-quartz between 300 and 1200 GPa: Characterization of alpha-quartz as a shock standard in the multimegabar regime SO PHYSICAL REVIEW B LA English DT Article ID AUGMENTED-WAVE METHOD; HIGH-PRESSURE; REFRACTIVE-INDEX; COMPRESSION; EQUATION; STATE; ALUMINUM; AEROGEL; METALS; SILICA AB a-quartz has been used prolifically in recent years as an impedance matching standard in the multimegabar regime (1 Mbar = 100 GPa). This is due to the fact that above similar to 90-100 GPa along the principal Hugoniot alpha-quartz becomes reflective, and thus shock velocities can be measured to high precision using velocity interferometry. This property allows for high-precision measurements, however, the accuracy of impedance matching measurements depends upon the knowledge of both the Hugoniot and the release or reshock response of alpha-quartz. Here, we present the results of several adiabatic release measurements of alpha-quartz from similar to 300-1200 GPa states along the principal Hugoniot using full density polymethylpentene (commonly known as TPX), and both similar to 190 and similar to 110 mg/cc silica aerogel standards. These data were analyzed within the framework of a simple, analytical model that was motivated by a first-principles molecular dynamics investigation into the release response of alpha-quartz. Combined, this theoretical and experimental study provides a method to perform impedance matching calculations without the need to appeal to any tabular equation of state for alpha-quartz. As an analytical model, this method allows for propagation of all uncertainty, including the random measurement uncertainties and the systematic uncertainties of the Hugoniot and release response of alpha-quartz. This work establishes alpha-quartz for use as a high-precision standard for impedance matching in the multimegabar regime. We also note that the experimentally validated model framework should prove to be useful in the development of wide range equations of state for silica, a major constituent in the Earth's crust and mantle. Such models are crucial for accurate simulations of high-velocity giant impacts that are thought to be prevalent in the final stages of terrestrial planet formation. C1 [Knudson, M.

TI Microscopic theory of the insulating electronic ground states of the actinide dioxides AnO(2) (An= U, Np, Pu, Am, and Cm) SO PHYSICAL REVIEW B LA English DT Article ID SPIN-LATTICE INTERACTION; NEUTRON-DIFFRACTION; URANIUM-DIOXIDE; MAGNETIC-SUSCEPTIBILITY; PHASE-TRANSITION; COMPLEX SPECTRA; LDA+U METHOD; 1ST-PRINCIPLES CALCULATIONS; MULTIPOLAR INTERACTIONS; PARAMAGNETIC-RESONANCE AB The electronic states of the actinide dioxides AnO(2) (with An= U, Np, Pu, Am, and Cm) are investigated employing first-principles calculations within the framework of the local density approximation + U(LDA + U) approach, implemented in a full-potential linearized augmented plane-wave scheme. A systematic analysis of the An-5f states is performed which provides intuitive connections between the electronic structures and the local crystalline fields of the f states in the AnO(2) series. Particularly the mechanisms leading to the experimentally observed insulating ground states are investigated. These are found to be caused by the strong spin-orbit and Coulomb interactions of the 5f orbitals; however, as a result of the different configurations, thismechanismworks in distinctly different ways for each of the AnO(2) compounds. In agreement with experimental observations, the nonmagnetic states of plutonium and curium dioxide are computed to be insulating, whereas those of uranium, neptunium, and americium dioxides require additional symmetry breaking to reproduce the insulator ground states, a condition which is met with magnetic phase transitions. We show that the occupancy of the An-f orbitals is closely connected to each of the appearing insulating mechanisms. We furthermore investigate the detailed constitution of the noncollinear multipolar moments for transverse 3q magnetic ordered states in UO2 and longitudinal 3q high-rank multipolar ordered states in NpO2 and AmO2.

TI Superconducting gap in LiFeAs from three-dimensional spin-fluctuation pairing calculations SO PHYSICAL REVIEW B LA English DT Article AB The lack of nesting of the electron and hole Fermi-surface sheets in the Fe-based superconductor LiFeAs, with a critical temperature of 18 K, has led to questions as to whether the origin of superconductivity in this material might be different from other Fe-based superconductors. Both angle-resolved photoemission and quasiparticle interference experiments have reported fully gapped superconducting order parameters with significant anisotropy. The system is also of interest because relatively strong correlations seem to be responsible for significant renormalization of the hole bands. Here we present calculations of the superconducting gap and pairing in the random-phase approximation using Fermi surfaces derived from measured photoemission spectra. The qualitative features of the gaps obtained in these calculations are shown to be different from previous two-dimensional theoretical works and in good agreement with experiment on the main Fermi-surface pockets. We analyze the contributions to the pairing vertex thus obtained and show that the scattering processes between electron and hole pockets that are believed to dominate the pairing in other Fe-based superconductors continue to do so in LiFeAs despite the lack of nesting, leading to gaps with anisotropic s(+/-) structure. Some interesting differences relating to the enhanced d(xy) orbital content of the LiFeAs Fermi surface are noted. C1 [Wang, Y.; Kreisel, A.; Hirschfeld, P.

The compound Sr2Fe1.5Mo0.5O6-delta (SFM) incorporates several FPs (Sr and Mo) into the crystalline network simultaneously while maintaining a stabilized perovskite structure. This polycrystalline SFM sample was irradiated with 200 keV He ions to a fluence of 5 x 10(16) ions cm(-2) (corresponding to a peak dose at 1.2 dpa) at room temperature to study radiation damage effects. Irradiated SFM sample decomposed into a layered Sr4FeMoO8-delta based phase and a Fe metallic phase, resulting in nano-crystalized grains with particle sizes around 7 nm. It was rationalized that He ion irradiation created a reduced atmosphere on the surface of SFM sample by preferentially sputtering oxygen atoms, consequently decomposing SFM and reducing Fe ions into metallic Fe phases. These results suggest that the stability of crystalline structures in reducing atmospheres may be an additional factor for consideration in the search for FP hosts in crystalline materials.

Co(OH)(2) can further convert to porous Co3O4 nanosheets via thermal decomposition. Their phases, structures and morphologies were investigated by X-ray diffraction (XRD), atomic force microscopy (AFM), and transmission electron microscopy (TEM). Both Co(OH)(2) and Co3O4 nanosheets can serve as potential candidates for anodes of Li-ion battery. The electrochemical study revealed that Co(OH)(2) and Co3O4 nanosheets delivered a reversible capacity of 600 and 700 mA h g(-1) after 40 cycles, respectively. Cyclic voltammetry (CV) curves also confirmed the relative stability of the as-synthesized electrode materials. This effective microwave-assisted route may be a promising approach for preparing other transition metal hydroxide/oxides for energy applications. (c) 2013 Elsevier B.V. All rights reserved.

YCoGa5 accommodates the HoCoGa5 type structure (space group P4/mmm (No. 123), Z = 1, a = 4.2131(6) angstrom, c = 6.7929(13) angstrom, which is isostructural to the extensively studied heavy fermion superconductor system CeMIn5 (M = Co, Rh, Ir) and the unconventional superconductor PuCoGa5 with T-c = 18.5 K. No superconductivity is observed down to 1.75 K. Band structure calculation results show that its band at the Fermi level is mainly composed of Co-3d and Ga-4p electrons states, which explains its similarity of physical properties to YbCoGa5 and LuCoGa5.

While the polarization of the top quark depends on the stop mixing, the chargino turns out to be fully polarized when the bottom Yukawa coupling can be neglected relative to the top Yukawa coupling. We compute the energy and angular spectra of the charged lepton in the chargino channel, which could serve as the spin analyzer of the chargino. In addition, we demonstrate the top polarization could have a significant impact on the selection efficiencies in direct stop samples at the LHC, while the effect from the chargino polarization is less pronounced. Two observables in the laboratory frame, the opening angle between the charged lepton and the b quark and the energy of the b quark, are also proposed to optimize searches in the chargino channel versus the top channel.

TI Universal Method for Separating Spin Pumping from Spin Rectification Voltage of Ferromagnetic Resonance SO PHYSICAL REVIEW LETTERS LA English DT Article AB We develop a method for universally resolving the important issue of separating spin pumping from spin rectification signals in bilayer spintronics devices. This method is based on the characteristic distinction of spin pumping and spin rectification, as revealed in their different angular and field symmetries. It applies generally for analyzing charge voltages in bilayers induced by the ferromagnetic resonance (FMR), independent of FMR line shape. Hence, it solves the outstanding problem that device-specific microwave properties restrict the universal quantification of the spin Hall angle in bilayer devices via FMR experiments. Furthermore, it paves the way for directly measuring the nonlinear evolution of spin current generated by spin pumping. The spin Hall angle in a Py/Pt bilayer is thereby directly measured as 0.021 +/- 0.015 up to a large precession cone angle of about 20 degrees. C1 [Bai, Lihui; Hyde, P.; Gui, Y.

CA CMS Collaboration TI Searches for new physics using the t(t)over-bar invariant mass distribution in pp collisions at root s=8 TeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID STANDARD MODEL; DECAY; HIERARCHY; BOSON; LHC AB Searches for anomalous top quark-antiquark production are presented, based on pp collisions at root s = 8 TeV. The data, corresponding to an integrated luminosity of 19.7 fb(-1), were collected with the CMS detector at the LHC. The observed t (t) over bar invariant mass spectrum is found to be compatible with the standard model prediction. Limits on the production cross section times branching fraction probe, for the first time, a region of parameter space for certain models of new physics not yet constrained by precision measurements.

CA IceCube Collaboration TI Evidence for High-Energy Extraterrestrial Neutrinos at the IceCube Detector SO SCIENCE LA English DT Article ID ICE AB We report on results of an all-sky search for high-energy neutrino events interacting within the IceCube neutrino detector conducted between May 2010 and May 2012. The search follows up on the previous detection of two PeV neutrino events, with improved sensitivity and extended energy coverage down to about 30 TeV. Twenty-six additional events were observed, substantially more than expected from atmospheric backgrounds. Combined, both searches reject a purely atmospheric origin for the 28 events at the 4 sigma level. These 28 events, which include the highest energy neutrinos ever observed, have flavors, directions, and energies inconsistent with those expected from the atmospheric muon and neutrino backgrounds. These properties are, however, consistent with generic predictions for an additional component of extraterrestrial origin.

Convergence of the 1-particle expansion was achieved through use of correlation consistent basis sets as large as aug-cc-pV8Z and aug-cc-pV9Z, followed by the application of a simple extrapolation formula in order to more closely approximate the basis set limit. Convergence of the n-particle expansion was addressed with a systematic sequence of coupled cluster methods up through CCSDTQ5. In 10 cases, coupled cluster theory was augmented with full configuration interaction. Each of the multiple sources of error was carefully monitored in order to minimize the overall uncertainty to the extent possible. Comparison with high-quality experimental values, many of them obtained from the active thermochemical tables, reveals overall close agreement with theory.

The chloromethyl groups of poly(styrene-co-4-acetoxystyrene-co-vinylbenzyl chloride-co-divinylbenzene) monolith enable post-polymerization hypercrosslinking catalyzed by ferric chloride in dichloroethane leading to a multitude of small pores thus enhancing the surface area. The acetoxy functionalities are easily deprotected using hydrazine to produce polar phenolic hydroxyl groups, which would be difficult to obtain by direct copolymerization of hydroxyl-containing monomers. The hypercrosslinking and deprotection reactions as well as their sequence were studied in detail with bulk polymer monoliths containing up to 50% 4-acetoxystyrene and its progress monitored by infrared spectrometry and nitrogen adsorption/desorption measurements. No significant difference was found for both possible successions. All monoliths were also prepared in a capillary column format, then deprotected and hypercrosslinked. Capillary columns were tested for the separation of small molecules using reversed phase and normal phase chromatographic modes. For polymer monoliths containing 50% deprotected 4-acetoxystyrene, column efficiencies of 40,000 plates/m for benzene in reversed phase mode and 31,800 plates/m for nitrobenzene in normal phase mode, were obtained. The percentage of hydroxyl groups in the monoliths enables modulation of polarity of the stationary phase. They also represent functionalities that are potentially suitable for further modifications and formation of new types of stationary phases for liquid chromatography. (C) 2013 Elsevier B.V.

TI Surfactant-mediated growth of ferromagnetic Mn delta-doped Si SO PHYSICAL REVIEW B LA English DT Article ID AUGMENTED-WAVE METHOD; EPITAXIAL-GROWTH; ELECTRONIC-STRUCTURE; MANGANESE SILICIDE; X-1) SURFACE; PB; SI(100); SEMICONDUCTORS; SI(001) AB We present an investigation of Mn delta-doped layers in Si(001) grown by molecular beam epitaxy. We discovered that a Pb surfactant has significant effect on the structural and magnetic properties of the submonolayer of Mn, which depends on the Si capping layer growth temperature T-Si, and the Mn coverage theta(Mn). The results presented in this paper identify three regions in the growth-phase diagram characterized by distinct magnetic behaviors and crystal structures. In one region, x-ray absorption fine structure and transmission electron microscopy experiments indicate that MnSi nanocrystallites form with B2-like crystal type structures. At the optimal growth conditions, T-Si = 200 degrees C and theta(Mn) = 0.26 monolayer, a ferromagnetic phase develops with a Curie temperature T-C > 400 K and a saturation moment m(sat) = 1.56 mu(B)/Mn, whereas T-C drops to zero for a control sample prepared without Pb. For T-Si > 200 degrees C MnSi-B20 type precipitates form with a T-C approximate to 170 K. Rutherford backscattering spectrometry shows that the increase in the remanent magnetization in these two phases is possibly correlated with an increase in the Mn substitutional fraction, which suggests that a Si1-xMnx dilute magnetic semiconductor may be forming in the matrix between the precipitates. Density functional calculations show that Pb changes the pathway by which the Mn atoms access the Si substitutional sites, MnSi. While the Pb increases the formation energy of Mn-Si at the Si surface, it enables substitutional incorporation by lowering the formation energy of Si vacancies by 0.92 eV.

In particular, we show that whenever a nonlinear equation admits solutions in terms of Jacobi elliptic functions cn(x, m) and dn(x, m), then it also admits solutions in terms of their sum as well as difference, i.e. dn(x, m) +/- root m cn(x, m). Further, we also show that whenever a nonlinear equation admits a solution in terms of dn(2)(x, m), it also has solutions in terms of dn(2)(x, m) +/- root m cn(x, m) dn(x, m) even though cn(x, m) dn(x, m) is not a solution of that nonlinear equation.

However, imaging with infrared light is impractical for superstrate CdTe cells because the glass substrate blocks transmission of light. It is shown that thermoreflectance - a lock-in technique that detects changes in the reflectivity of visible light - can circumvent this problem and achieve thermal images with spatial resolution limited only by the imaging wavelength. The diagnostic is used to show that a particular defect is a resistive shunt. C1 [Katz, N.; Patterson, M.; Hudgings, J.] Mt Holyoke Coll, S Hadley, MA 01075 USA.

The time-independent Schrodinger equation in hyperspherical coordinates is solved to determine energy dependent probabilities and cross sections over collision energies ranging from ultracold to 0.35 eV and for total angular momentum quantum number J = 0. A J-shifting approximation is then used to compute initial state selected reactive rate coefficients in the temperature range T = 1 - 400 K. Results are found to be in reasonable agreement with available quasiclassical trajectory calculations. Results indicate that rate coefficients for O-2 formation increase with increasing the OH vibrational level except at low and ultralow temperatures where OH(v = 0) exhibits a slightly different trend. It is found that vibrational relaxation of OH in v = 2 and v = 3 vibrational levels is dominated by a multi-quantum process. (C) 2013 AIP Publishing LLC. C1 [Pradhan, G. B.; Juanes-Marcos, J.

TI A Classical Trajectory Study of the Dissociation and lsomerization of C2H5 SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID ACTIVE THERMOCHEMICAL TABLES; ETHYL RADICAL DECOMPOSITION; POTENTIAL-ENERGY SURFACE; AB-INITIO; ELECTRONIC-STRUCTURE; MOLECULAR-SYSTEMS; TRANSITION-STATE; RATE CONSTANTS; BASIS-SET; DYNAMICS AB Motivated by photodissociation experiments in which non-RRKM nanosecond lifetimes of the ethyl radical were reported, we have performed a classical trajectory study of the dissociation and isomerization of C2H5 over the energy range 100-150 kcal/mol. We used a customized version of the AIREBO semiempirical potential (Stuart, S. J.; et al. J. Chem. Phys. 2000, 112, 6472-6486) to more accurately describe the gas-phase decomposition of C2H5. This study constitutes one of the first gas-phase applications of this potential form. At each energy, 10 000 trajectories were run and all underwent dissociation in less than 100 ps. The calculated dissociation rate constants are consistent with RRKM models; no evidence was found for nanosecond lifetimes. An analytic kinetics model of isomerization/dissociation competition was developed that incorporated incomplete mode mixing through a postulated divided phase space. The fits of the model to the trajectory data are good and represent the trajectory results in detail through repeated isomerizations at all energies. The model correctly displays single exponential decay at lower energies, but at higher energies, multiexponential decay due to incomplete mode mixing becomes more apparent. At both ends of the energy range, we carried out similar trajectory studies on CD2CH3 to examine isotopic scrambling. The results largely support the assumption that a H or a D atom is equally likely to dissociate from the mixed-isotope methyl end of the molecule. The calculated fraction of products that have the D atom dissociation is similar to 20%, twice the experimental value available at one energy within our range. The calculated degree of isotopic scrambling is non-monotonic with respect to energy due to a non-monotonic ratio of the isomerization to dissociation rate constants.

Line shapes were fit using Fourier transforms of a parametrized time correlation function, including Doppler and velocity-dependent collisional broadening, and collisional shifts. Deviations from Voigt line shapes can be equally well fit by modeling the narrowing with a speed-dependent collision model or with a velocity-changing collisional narrowing model. Pressure broadening coefficients were observed with little rotational state dependence, in the range of 0.070-0.075 cm(-1) atm(-1). In contrast, stronger and qualitatively different rotational state dependences are observed for both pressure-dependent blue shift coefficients and the narrowing parameters. No asymmetry in the pressure broadened lines was observed. C1 [Forthomme, Damien; McRaven, Christopher P.; Sears, Trevor J.; Hall, Gregory E.] Brookhaven Natl Lab, Dept Chem, Upton, NY 11973 USA.

TI Mobility of Supercooled Liquid Toluene, Ethylbenzene, and Benzene near Their Glass Transition Temperatures Investigated Using Inert Gas Permeation SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID SPATIALLY HETEROGENEOUS DYNAMICS; STOKES-EINSTEIN LAW; AROMATIC HYDROCARBONS; PHYSICAL PROPERTIES; SELF-DIFFUSION; TRANSLATIONAL DIFFUSION; ROTATIONAL DIFFUSION; CORRESPONDING STATES; DENSITY-DEPENDENCE; O-TERPHENYL AB We investigate the mobility of supercooled liquid toluene, ethylbenzene, and benzene near their respective glass transition temperatures (T-g). The permeation rate of Ar, Kr, and Xe through the supercooled liquid created when initially amorphous overlayers are heated above their glass transition temperature is used to determine the diffusivity. Amorphous benzene crystallizes at temperatures well below its T-g, and as a result, the inert gas underlayer remains trapped until the onset of benzene desorption. In contrast, for toluene and ethylbenzene the onset of inert gas permeation is observed at temperatues near T-g. The inert gas desorption peak temperature as a function of the heating rate and overlayer thickness is used to quantify the diffusivity of supercooled liquid toluene and ethylbenzene from 115 to 135 K. In this temperature range, diffusivities are found to vary across 5 orders of magnitude (similar to 10(-14) to 10(-9) cm(2)/s). The diffusivity data are compared to viscosity measurements and reveal a breakdown in the Stokes-Einstein relationship at low temperatures. However, the data are well fit by the fractional Stokes-Einstein equation with an exponent of 0.66. Efforts to determine the diffusivity of a mixture of benzene and ethylbenzene are detailed, and the effect of mixing these materials on benzene crystallization is explored using infrared spectroscopy.

The new partition function allows the Active Thermochemical Tables (ATcT) approach to be applied on the available experimental and theoretical data relating to water dimer thermochemistry, leading to accurate water dimer enthalpies of formation of -499.115 +/- 0.052 kJ mol(-1) at 298.15 K and -491.075 +/- 0.080 kJ mo1(-1) at 0 K. With the current ATcT enthalpy of formation of the water monomer, -241.831 +/- 0.026 kJ mol(-1) at 298.15 K (-238.928 kJ mol(-1) at 0 K), this leads to the dimer bond dissociation enthalpy at 298.15 K of 15.454 +/- 0.074 kJ mo1(-1) and a 0 K bond dissociation energy of 13.220 +/- 0.096 kJ mol(-1) (1105 +/- 8 cm(-1)), the latter being in perfect agreement with recent experimental and theoretical determinations. The new partition function of water dimer allows the extraction and tabulation of heat capacity, entropy, enthalpy increment, reduced Gibbs energy, enthalpy of formation, and Gibbs energy of formation. Newly developed tabulations of analogous thermochemical properties for gas-phase water monomer and for water in condensed phases are also given, allowing the computations of accurate equilibria between the dimer and monomer in the 200-500 K range of temperatures.

Thiophenoxy radicals were produced by photodetachment of the thiophenoxide anion followed by photodissociation at 248 nm (5.0 eV), 193 nm (6.4 eV), and 157 nm (7.9 eV). Experimental results indicate two major competing dissociation channels leading to SH + C6H4 (o-benzyne) and CS + C5H5 (cyclopentadienyl) with a minor contribution of S + C6H5 (phenyl). Photofragment mass distributions and translational energy distributions were measured at each dissociation wavelength. Transition states and minima for each reaction pathway were calculated using density functional theory to facilitate experimental interpretation. The proposed dissociation mechanism involves internal conversion from the initially prepared electronic excited state to the ground electronic state followed by statistical dissociation. Calculations show that SH loss involves a single isomerization step followed by simple bond fission. For both SH and S loss, C-S bond cleavage proceeds without an exit barrier. By contrast, the CS loss pathway entails multiple transition states and minima as it undergoes five membered ring formation and presents a small barrier with respect to products. The calculated reaction pathway is consistent with the experimental translational energy distributions in which the CS loss channel has a broader distribution peaking farther away from zero than the corresponding distributions for SH loss.

In pulsed-photolytic Cl-initiated oxidation of n-butanol, the time-resolved and isomer-specific product concentrations were probed using multiplexed tunable synchrotron photoionization mass spectrometry (MPIMS). The interpretation of the experimental data is underpinned by potential energy surfaces for the reactions of O-2 with the four hydroxybutyl isomers (1-hydroxybut-1-yl, 1-hydroxybut-2-yl, 4-hydroxybut-2-yl, and 4-hydroxybut-1-yl) calculated at the CBS-QB3 and RQCISD(T)/cc-pV infinity Z//B3LYP/6-311++G(d,p) levels of theory. The observed product yields display substantial temperature dependence, arising from a competition among three fundamental pathways: (1) stabilization of hydroxybutylperoxy radicals, (2) bimolecular product formation in the hydroxybutyl + O-2 reactions, and (3) decomposition of hydroxybutyl radicals. The 1-hydroxybut-1-yl + O-2 reaction is dominated by direct HO2 elimination from the corresponding peroxy radical forming butanal as the stable coproduct. The chemistry of the other three hydroxybutylperoxy radical isomers mainly proceeds via alcohol-specific internal H-atom abstractions involving the H atom from either the OH group or from the carbon attached to the -OH group. We observe evidence of the recently reported water elimination pathway (Welz et al. J. Phys. Chem. Lett. 2013, 4 (3), 350-354) from the 4-hydroxybut-2-yl + O-2 reaction, supporting its importance in gamma-hydroxyalkyl + O-2 reactions. Experiments using the 1,1-d2 and 4,4,4-d(3) isotopologues of n-butanol suggest the presence of yet unexplored pathways to acetaldehyde.

Even at this energy, there is extensive fragmentation of the phenoxy radical upon photoionization, which is attributed to ionizing transitions that populate low-lying excited electronic states of the cation. For phenoxy radicals with less than similar to 1 eV of internal energy, we find a cross-section for the production of the phenoxy cation of 14.8 +/- 3.8 Mb. For radicals with higher internal energy, dissociative ionization is the dominant process, and for internal energies of similar to 2.7-3.7 eV, we find a total cross-section (photoionization plus dissociative ionization) of 22.3 +/- 4.1 Mb. The results are discussed relative to the recently reported photoionization cross-section of phenol. C1 [Xu, Hong; Pratt, S. T.] Argonne Natl Lab, Argonne, IL 60439 USA.

Within this formulation the dynamical phase space consists of only the microscopic populations of the various isomers making up the reactive complex, while the bimolecular reactants and products are treated equally as sources and sinks. This reformulation yields compact expressions for the phenomenological rate coefficients describing all chemical processes, i.e., internal isomerization reactions, bimolecular-to-bimolecular reactions, isomer-to-bimolecular reactions, and bimolecular-to-isomer reactions. The applicability of the detailed balance condition is discussed and confirmed. We also consider the situation where some of the chemical eigenvalues approach the energy relaxation time scale and show how to modify the phenomenological rate coefficients so that they retain their validity.

The measurements were in excellent agreement with the only previous determination at room temperature and show a marked increase in the rate coefficient as the temperature is lowered, with the results being well represented by the equation k(T) = 1.79 x 10(-11) (T/300 K)(-0.67) cm(3) molecule(-1) s(-1), with a root-mean-square (statistical) error of 0.61 X 10(-11) cm(3) molecule(-1) s(-1), to which should be added 10% estimated likely systematic error. High accuracy ab initio quantum chemical calculations coupled with variational two-transition state theory calculations were also performed and demonstrate excellent agreement within the combined experimental and predicted theoretical uncertainties. The theoretical rate coefficients, adjusted within expected uncertainties, can be accurately reproduced over the 5 to 400 K temperature range by the expression [(1.97 x 10(-8)) T-1.51 exp(-3.24/T) + (4.85 X 10(-13)) T-0.563 exp (17.6/T)] cm(3) molecule(-1) s(-1), where T is in K The new measurements are likely to be of interest to astrochemical and planetary atmospheric modelers.

Alkyl and Benzyl Derivatives of 5-Membered Ring Heterocycles SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID INDUCED REDOX REACTIONS; SOLVENT-EXTRACTION; AQUEOUS-SOLUTIONS; METAL-IONS; FACILITATED TRANSFER; GAMMA-IRRADIATION; CONSTITUENT IONS; STRONTIUM IONS; ANIONS; SEPARATIONS AB In order to use hydrophobic room temperature ionic liquids (ILs) as diluents in nuclear separations for advanced fuel cycles, it is desirable to reduce the breakdown of the constituent ions caused by ionizing radiation. In this series, we survey radiation stability for different classes of organic cations used to formulate ILs. 'While radiolysis of 1alky1-3-methylimidazolium cations has been extensively studied, there have not been complementary studies of 1-benzyl derivatives of these cations nor organic cations that are derived from 5-membered ring heterocycles other than imidazole, such as 1,2,4-triazole and thiazole. In part 1, we establish the fragmentation pathways for such cations and quantify product yields for 2.5 MeV electron beam radiolysis of these aromatic cations. Radiolytic reduction of 1-benzyl cations derived from imidazole and 1,2,4-triazole is shown to cause the elimination of benzyl radicals from their electron adducts, whereas this elimination does not occur in the thiazole derivatives due to stabilization of the excess electron as a dimer radical cation. No such elimination occurs in the corresponding 1-alkyl derivatives, but there is significant C-N and C-C bond fragmentation in the aliphatic arms. As such bond dissociation reactions are irreversible, there is significant loss of 1-alkyl cations during the radiolysis. For 1-benzyl derivatives, this electronic excitation causes fragmentation of the C-N bonds in the benzyl arms with the release of the corresponding base and the benzyl carbocation that can subsequently attack this base or add to another cation. Such systems exhibit more predictable fragmentation patterns and yield well-defined products; some of the systems also exhibit increased radiation resistance. The C-N bond fragmentation in the reduced cations can be further suppressed through the use of appropriate electron scavengers, including acids and aromatic imide anions. The observed trends are rationalized using density functional theory calculations, and the implications of these results for the design of IL diluents are examined.

Improved Radiation Resistance through Charge De localization in 1-Benzylpyridinium SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID INDUCED REDOX REACTIONS; PULSE-RADIOLYSIS; ELECTRON SOLVATION; RADICAL CATIONS; DIMER CATIONS; BENZENE DIMER; HALOCARBON MATRICES; IMIDAZOLIUM CATIONS; ABSORPTION SPECTRA; GAMMA-IRRADIATION AB Hydrophobic room-temperature ionic liquids (ILs) hold promise as replacements for molecular diluents for processing of used nuclear fuel as well as for the development of alternative separations processes, provided that the solvent can be made resistant to ionizing radiation. We demonstrate that 1-benzylpyridinium cations are uniquely suited as radiation resistant cations due to the occurrence of charge delocalization in both their reduced and oxidized forms in the ILs. It is suggested that the excess electron and hole in the latter ILs are stabilized through the formation of itelectron sandwich dimers that are analogous to the well-known dimer radical cations of aromatic molecules. This charge delocalization dramatically reduces the yield of fragmentation by deprotonation and the loss of benzyl arms, thereby providing a synthetic path to radiation resistant ILs that are suitable for nuclear fuel processing.

Guanidiniuni Cations SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID INDUCED REDOX REACTIONS; NEUTRALIZATION-REIONIZATION; GAMMA-IRRADIATION; CONSTITUENT IONS; AB-INITIO; IMIDAZOLIUM; CHEMISTRY; SOLVENTS; DENSITY; ANIONS AB Due to their superb structural versatility, guanidinium cations find increasing use as constituent ions in room temperature ionic liquids (ILs). This versatility allows fine-tuning of hydrophobicity, which is an important concern for the use of ILs as diluents for metal ion separations. However, the presence of six C-N bonds in such cations poses a question, whether the guanidinium based ILs can be considered as diluents for nuclear separations, given that the radiation emitted by the decaying radionuclides can break these relatively weak bonds over the use cycle of the solvent. As nothing is presently known about the radiolytic stability of the guanidinium cations, we addressed this question using 2-dialkylamino-1,3-dimethylimidazolidine based cations (R = Et, Pr, and Bu) as a representative model for the entire class of such cations, and assessed their stability in 2.5 MeV electron beam radiolysis. Electron paramagnetic resonance spectroscopy, nuclear magnetic resonance spectroscopy, and mass spectrometry have been used to establish chemical mechanisms for radiation damage in guanidinium cations. Our conclusion is that radiation stability of these cations is not significantly different from that of more familiar aliphatic and aromatic IL cations. In fact, these cations yield exceptionally stable radicals, and fragmentation occurs only in their radiolytically generated excited states. The predominant chemical pathway for the cation decomposition is the elimination of their aliphatic arms, with radiolytic yields of 0.65 to 1.06 to 1.46 per 100 eV from R = Et to R = Bu, respectively. The total loss of the parent cation was estimated as 2.62, 1.65, and 1.98 species per 100 eV. While this attrition is not negligible, it is comparable to other organic cations that have fewer fissile C-N bonds. Many of the products are either modified guanidinium ions or protonated bases that are not expected to interfere with radionuclide separations.

It is composed of thousands of subunits including hexameric and pentameric proteins that form a shell to encapsulate the enzymes ribulose 1,5-bisphosphate carboxylase/oxygenase and carbonic anhydrase. Here, we describe the stages of carboxysome assembly and the requisite gene products necessary for progression through each. Our results demonstrate that, unlike membrane-bound organelles of eukaryotes, in carboxysomes the interior of the compartment forms first, at a distinct site within the cell. Subsequently, shell proteins encapsulate this procarboxysome, inducing budding and distribution of functional organelles within the cell. We propose that the principles of carboxysome assembly that we have uncovered extend to diverse bacterial microcompartments.

With this feature paper, we aim to fulfill two goals: (1) give a full description of the photoinduced TRMC technique, including experimental details and data analysis, and discuss to what extent the TRMC technique differs from more conventional DC techniques and (2) illustrate the potential of this technique for probing charge carrier dynamics in photoactive materials. For these reasons recent studies on conjugated polymer:fullerene blends will be presented and discussed. The findings from these studies have advanced the insight into the mechanism of charge carrier generation and decay in polymer:fullerene blends, which allows us to improve the efficiency of organic photovoltaic cells based on this active layer architecture. In short, it is shown how the TRMC technique can be used as a versatile method to screen the potential of new photovoltaic materials.

This might indicate a new route for the synthesis of inorganic/organic conductors of various compositions and properties and could greatly expand the field of conductive polymers. Here, we present a study of the phase behavior and electrical properties of K3Fe(CN)(6) up to similar to 15 GPa using Raman spectroscopy, synchrotron X-ray diffraction, and impedance spectroscopy at room temperature. In this pressure range, two new crystalline phases were identified, and their unit cells and space groups were determined. The cyanide ions react to form conjugated C=N bonds in two steps, and the electronic conductivity is enhanced by 3 orders of magnitude, from 10(-7) to 10(-4) S.cm(-1). Because this material is also an ionic conductor, these studies might "shed light" on the development of new cathode materials for alkali metal batteries. Enhancing the electrical conductivity by applying high pressure to compounds containing triple bonds could provide a potential route for synthesizing multifunctional conductive materials.

The structural study of the samples was performed by Fourier transform infrared spectroscopy (FTIR), X-ray absorption spectroscopy (XAS), and powder X-ray diffraction (XRD). While XRD verified the formation of single spinel phases with lattice parameters reduced by increasing Cr substitution, FTIR and XAS provided insight into the subsequently increased covalence of the chemical bonding of the spinels. The mixed transition-metal spinel oxides were employed as working electrodes in Li metal batteries. In agreement with the literature, the spinel oxides experience amorphization during the first discharge, as shown by ex situ XRD and selected area electron diffraction (SAED). The electrochemical activity of the spinel oxides was found to diminish with Cr content so that ZnCr2O4 is completely inactive even when the material is nanosized and in the presence of a large amount of conductive additive. Comparison with mixtures of ZnO and Cr2O3 led to the conclusion that the conducting band of the ternary oxide, which would be injected with electrons during reduction, is raised with respect to the individual binary oxides to the point that the overpotential required to drive a conversion reaction displaces the experimental electrochemical potential to be extremely close to, or even lower than, that of Li metal.

Using ab initio molecular dynamics (AIMD) and thermodynamic integration techniques, we compute Delta G(t) for the virtual transfer of a Li+ from a LiC6 anode slab, with pristine basal planes exposed, to liquid ethylene carbonate confined in a nanogap. The onset of delithiation, at Delta G(t) = 0, is found to occur on LiC6 anodes with negatively charged basal surfaces. These negative surface charges are evidently needed to retain Li+ inside the electrode and should affect passivation ("SEI") film formation processes. Fast electrolyte decomposition is observed at even larger electron surface densities. By assigning the experimentally known voltage (0.1 V vs Li+/Li metal) to the predicted delithiation onset, an absolute potential scale is obtained. This enables voltage calibrations in simulation cells used in AIMD studies and paves the way for future prediction of voltage dependences in interfacial processes in batteries.

To be able to tailor the adsorption of aromatic molecules of these surfaces, the synergistic interactions within the surface and their effects on adsorbates must be elucidated. In this work, we examine the energetic and electronic interaction between benzene and several model PdFe bimetallic surfaces, with low and high Pd coverage limits, using density functional theory and compare our results with the adsorption of benzene on a pure Fe (110) surface. The adsorption energy trends on these model surfaces show that the interactions between the Pd and Fe significantly decrease the strength of benzene's adsorption on surface Pd without significantly weakening its adsorption on the adjacent surface Fe. From the electronic analyses, the decreased adsorption strength of benzene on the model PdFe surfaces is due to the shift in the Pd's d-band center away from the Fermi level. These results show that aromatic compounds will preferentially adsorb onto any exposed Fe in a PdFe surface due to the greater availability of electronic states near the Fermi level. Therefore, under typical catalytic conditions, the strength of the adsorption of benzene can be tailored on the basis of the amount of Pd added to an Fe surface because increasing the concentration of Pd in the surface will increase the amount of interaction between the adsorbate and the modified surface Pd.

Its binding structure and mechanism as a function of the oxidation states of metal oxide nanoparticle surfaces are not well characterized. Here we present an in situ sum-frequency generation vibrational spectroscopy (SFG-VS) and spin-polarized density functional theory (DFT) study on the binding of deuterated acetic acid on ceria nanoparticles (GNPs) in aqueous solution. SFG spectra from the CNP surface revealed that the binding modes of the carboxylate group depend on the oxidation states of the cerium on the surface. SFG polarization analysis suggested that bidentate chelating and bridging binding modes coexist on partially reduced ceria surfaces, while oxidized ceria surfaces are dominated by the bidentate bridging mode. DFT calculations show consistent results that dissociative adsorption is more thermodynamically stable than molecular state adsorption. Dissociative adsorption to a highly undercoordinated corner site on the model ceria cluster is more favorable compared to the sites on a flat surface. This direct spectroscopic evidence from SFG spectra of a ceria nanoparticle and computational results on a model ceria cluster help to clarify the binding structures and the dissociative binding mechanism on ceria nanoparticles. These results demonstrate that the SFG method is applicable to directly characterize reactions and binding chemistry at the nanoparticle surface buried in aqueous solution.

Rational engineering of such persistent coherences could open a new way to increase energy conversion rates in man-made photovoltaic and photocatalytic materials. Therefore, a comprehensive understanding of the fundamental principles behind the long-lived coherences is necessary. In this work we show that the main factor determining the decoherence rates is the magnitude of the nuclear-induced fluctuation of the energy gap between the electronic states of interest, rather than the electron nuclear correlation on its own. Utilizing combined atomistic and electronic structure calculations, we demonstrate an inverse relationship between decoherence times and magnitude of the energy gap fluctuation. We also show that the energy gap fluctuation can often correlate with the gap itself. For sufficiently small energy gaps, the coherence time can be nearly an order of magnitude larger than the electron nuclear correlation time.

Dormant persister cells that are tolerant to killing by antibiotics are responsible for this apparent paradox. Persisters are phenotypic variants of normal cells and pathways leading to dormancy are redundant, making it challenging to develop anti-persister compounds. Biofilms shield persisters from the immune system, suggesting that an antibiotic for treating a chronic infection should be able to eradicate the infection on its own. We reasoned that a compound capable of corrupting a target in dormant cells will kill persisters. The acyldepsipeptide antibiotic (ADEP4) has been shown to activate the ClpP protease, resulting in death of growing cells. Here we show that ADEP4-activated ClpP becomes a fairly nonspecific protease and kills persisters by degrading over 400 proteins, forcing cells to self-digest. Null mutants of clpP arise with high probability, but combining ADEP4 with rifampicin produced complete eradication of Staphylococcus aureus biofilms in vitro and in a mouse model of a chronic infection. Our findings indicate a general principle for killing dormant cells-activation and corruption of a target, rather than conventional inhibition. Eradication of a biofilm in an animal model by activating a protease suggests a realistic path towards developing therapies to treat chronic infections. C1 [Conlon, B. P.; Fleck, L. E.; Isabella, V.

TI Effective orbital symmetry of CuO: Examination by nonresonant inelastic x-ray scattering SO PHYSICAL REVIEW B LA English DT Article ID ELECTRONIC-STRUCTURE; EXCITATIONS; EDGE AB We report on measurements of nonresonant inelastic x-ray scattering (NIXS) to unravel the effective symmetry of Cu 3d orbitals in the ground state of CuO. A clear feature of energy loss at about 2 eV exists in the NIXS spectrum, arising from dd excitations; the intensities of these excitations display a pronounced anisotropy. The comparison between the measured angular distributions of scattering and those from theoretical predictions by the tesseral harmonics indicates that, in terms of a hole picture, the lowest-energy dd excitation is the orbital transition x(2) - y(2) -> xy. In addition, the transition x(2) - y(2) -> 3z(2) - r(2) has an energy higher than x(2) - y(2) -> yz/zx, in contrast to a previous interpretation. Our results imply a large Jahn-Teller-like splitting between x(2) - y(2) and 3z(2) - r(2) orbitals. The theory assuming a C-4h symmetry explains the angular dependence of the NIXS spectra fairly well, implying that this symmetry is a reasonable approximation. This demonstrates that NIXS can provide important information for modeling of the electronic structure of d ions embedded in a complicated crystal field. C1 [Wu, W. B.; Hiraoka, N.; Huang, D.

Using an approach based on sequential convex programming, we demonstrate that quantum gate transformations can be made substantially robust against uncertainties while simultaneously using limited resources of control amplitude and bandwidth. Achieving such a high degree of robustness requires a quantitative model that specifies the range and character of the uncertainties. Using a model of a controlled one-qubit system for illustrative simulations, we identify robust control fields for a universal gate set and explore the trade-off between the worst-case gate fidelity and the field fluence. Our results demonstrate that, even for this simple model, there exists a rich variety of control design possibilities. In addition, we study the effect of noise represented by a stochastic uncertainty model. C1 [Kosu, Robert L.] SC Solut Inc, Sunnyvale, CA 94085 USA.

TI CALIFA Barrel prototype detector characterisation SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Calorimetry; Scintillator materials; CALIFA; (RB)-B-3; Avalanche photodiodes; CsI(Tl) ID CALORIMETER; CRYSTALS AB Well established in the field of scintillator detection, Caesium Iodide remains at the forefront of scintillators for use in modern calorimeters. Recent developments in photosensor technology have lead to the production of Large Area Avalanche Photo Diodes (LAAPDs), a huge advancement on traditional photosensors in terms of high internal gain, dynamic range, magnetic field insensitivity, high quantum efficiency and fast recovery time. The (RB)-B-3 physics programme has a number of requirements for its calorimeter, one of the most challenging being the dual functionality as both a calorimeter and a spectrometer. This involves the simultaneous detection of -300 MeV protons and gamma rays ranging from 0.1 to 20 MeV. This scintillator - photosensor coupling provides an excellent solution in this capacity, in part due to the near perfect match of the LAAPD quantum efficiency peak to the light output wavelength of CsI(Tl). Modern detector development is guided by use of Monte Carlo simulations to predict detector performance, nonetheless it is essential to benchmark these simulations against real data taken with prototype detector arrays. Here follows an account of the performance of two such prototypes representing different polar regions of the Barrel section of the forthcoming CALIFA calorimeter. Measurements were taken for gammaray energies up to 15.1 MeV (Maier-Leibnitz Laboratory, Garching, Germany) and for direct irradiation with a 180 MeV proton beam (The Svedberg Laboratoriet, Uppsala, Sweden). Results are discussed in light of complementary GEANT4 simulations. (c) 2013 Elsevier B.V. All rights reserved.

TI Time-correlated pulse-height measurements of low-multiplying nuclear materials SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Liquid scintillators; Sub-critical multiplication; Neutron-gamma correlation; MCNPX-PoliMi AB Methods for the determination of the subcritical neutron multiplication of nuclear materials are of interest in the field of nuclear nonproliferation and safeguards. A series of measurements were performed at the Joint Research Center facility in Ispra, Italy to investigate the possibility of using a time-correlated pulse-height (TCPH) analysis to estimate the sub-critical multiplication of nuclear material. The objective of the measurements was to evaluate the effectiveness of this technique, and to benchmark the simulation capabilities of MCNPX-PoliMi/MPPost. In this campaign, two low-multiplication samples were measured: a 1-kg mixed oxide (MOX) powder sample and several low-mass plutonium-gallium (PuGa) disks. The measured results demonstrated that the sensitivity of the TCPH technique could not clearly distinguish samples with very-low levels of multiplication. However, the simulated TCPH distributions agree well with the measured data, within 12% for all cases, validating the simulation capabilities of MCNPX-PoliMi/MPPost. To investigate the potential of the TCPH method for identifying high-multiplication samples, the validated MCNPX-PoliMi/MPPost codes were used to simulate sources of higher multiplications. Lastly, a characterization metric, the cumulative region integral (CRI), was introduced to estimate the level of multiplication in a source. However, this response was shown to be insensitive over the range of multiplications of interest. (c) 2013 Elsevier B.V. All rights reserved. C1 [Miller, E. C.; Dolan, J. L.; Clarke, S. D.; Pozzi, S.

The accelerated carbon beam was observed successfully and the obtained current was 9.22 mA for C4+. To confirm the capability of the DPIS, we succeeded in accelerating 60 mA carbon ions with the DPIS in 2004 (Okamura et al., 2004; Kashiwagi and Hattori, 2004) 2 and 3. We have studied a multi-beam type RFQ with an interdigital-H (IH) cavity that has a power-efficient structure in the low energy region. We designed and manufactured a two-beam type RFQ linac as a prototype for the multi-beam type linac; the beam acceleration test of carbon beams showed that it successfully accelerated from 5 keV/u up to 60 keV/u with an output current of 108 mA (2 x 54 mA/channel) (Ishibashi et al., 2011) [4]. We believe that the acceleration techniques of DPIS and the multi-beam type IH-RFQ linac are technical breakthroughs for heavy-ion inertial confinement fusion (HIF). The conceptual design of the RF linac with these techniques for HIF is studied. New accelerator-systems using these techniques for the HIF basic experiment are being designed to accelerate 400 mA carbon ions using four-beam type IH-RFQ linacs with DPIS. A model with a four-beam acceleration cavity was designed and manufactured to establish the proof of principle (PoP) of the accelerator. (c) 2013 Published by Elsevier B.V.

TI Operational experience, improvements, and performance of the CDF Run II silicon vertex detector SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Silicon; Vertex detector; CDF; Tevatron Run II; Detector operations ID TRACKER; UPGRADE; READOUT; TRIGGER; LINK AB The Collider Detector at Fermilab (CDF) pursues a broad physics program at Fermilab's Tevatron collider. Between Run II commissioning in early 2001 and the end of operations in September 2011, the Tevatron delivered 12 fb(-1) of integrated luminosity of p (p) over bar collisions at root s =1.96 TeV. Many physics analyses undertaken by CDF require heavy flavor tagging with large charged particle tracking acceptance. To realize these goals, in 2001 CDF installed eight layers of silicon microstrip detectors around its interaction region. These detectors were designed for 2-5 years of operation, radiation doses up to 2 Mrad (0.02 Gy), and were expected to be replaced in 2004. The sensors were not replaced, and the Tevatron run was extended for several years beyond its design, exposing the sensors and electronics to much higher radiation doses than anticipated. In this paper we describe the operational challenges encountered over the past 10 years of running the CDF silicon detectors, the preventive measures undertaken, and the improvements made along the way to ensure their optimal performance for collecting high quality physics data. In addition, we describe the quantities and methods used to monitor radiation damage in the sensors for optimal performance and summarize the detector performance quantities important to CDF's physics program, including vertex resolution, heavy flavor tagging, and silicon vertex trigger performance.

These measurements were conducted at the Free Electron Laser (FEL) facility of the Jefferson National Accelerator Laboratory (JLab) using a 100 mev electron beam from an energy recovery linear accelerator. The beam was directed successively through 6 mm, 4 mm, and 2 mm diameter apertures of length 127 mm in aluminum at a maximum current of 4.3 mA (430 kW beam power). This study was conducted to characterize radiation levels for experiments that need to operate in this environment, such as the proposed DarkLight Experiment. We rind that sustained transmission of a 430 kW continuouswave (CW) beam through a 2 mm aperture is feasible with manageable beam-related backgrounds. We also rind that during beam-off, RE-on operation, multipactoring inside the niobium cavities of the accelerator cryomodules is the primary source of ambient radiation when the machine is tuned for 130 mev operation.

TI Performance assessment of self-interrogation neutron resonance densitometry for spent nuclear fuel assay SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE SINRD; NDA; Spent fuel; Fissile content; Safeguards; Nonproliferation AB Self Interrogation Neutron Resonance Densitometry (SINRD) is one of several nondestructive assay (NDA) techniques being integrated into systems to measure spent fuel as part of the Next Generation Safeguards Initiative (NGSI) Spent Fuel Project. The NGSI Spent Fuel Project is sponsored by the US Department of Energy's National Nuclear Security Administration to measure plutonium in, and detect diversion of fuel pins from, spent nuclear fuel assemblies. SINRD shows promising capability in determining the 239Pu and 235U content in spent fuel. SINRD is a relatively low-cost and lightweight instrument, and if is easy to implement in the field. The technique makes use of the passive neutron source existing in a spent fuel assembly, and it uses ratios between the count rates collected in fission chambers that are covered with different absorbing materials. These ratios are correlated to key attributes of the spent fuel assembly, such as the total mass of Pu-239 and U-235. Using count rate ratios instead of absolute count rates makes SINRD less vulnerable to systematic uncertainties. Building upon the previous research, this work focuses on the underlying physics of the SINRD technique: quantifying the individual impacts on the count rate ratios of a few important nuclides using the perturbation method; examining new correlations between count rate ratio and mass quantities based On the results of the perturbation study; quantifying the impacts on the energy windows of the filtering materials that cover the fission chambers by tallying the neutron spectra before and after the neutrons go through the filters; and identifying the most important nuclides that cause cooling-time variations in the count rate I atios. The results of these studies show that U-235 content has a major impact on the SINRD signal in addition to the (PU)-P-239 content. Plutonium-241 and 211Am are the two main nuclides responsible for the variation in the count rate ratio with cooling time. In short, this work provides insights into some of the main factors that affect the performance of SINRD, and it should help improve the hardware design and the algorithm used to interpret the signal for the SINRD technique. In addition, the modeling and simulation techniques used in this work can be easily adopted for analysis of other NDA systems, especially when complex systems like spent nuclear fuel are involved.

The technique is based on system identification that actively cancels the microphonic noise. A sensor is used to measures mechanical disturbances that cause vibration on the detector assembly, and the digital adaptive filtering estimates the impact of these disturbances on the microphonic noise. The noise then can be subtracted from the actual detector measurement. In this paper the technique is presented and simulations are used to support this approach. (C) 2013 Elsevier B.V.

TI EJ-309 pulse shape discrimination performance with a high gamma-ray-to-neutron ratio and low threshold SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Liquid scintillator; Pulse shape discrimination; Spent fuel; Low threshold AB Measuring neutrons in the presence of high gamma ray fluence is a challenge with multi particle detectors. Organic liquid scintillators such as the EJ-309 are capable of accurate pulse-shape discrimination (PSD) but the chance for particle misclassification is not negligible for some applications. By varying the distance from an EJ-309 scintillator to a strong-gamma-ray source and keeping a weak-neutron source at a fixed position, various gamma-to-neutron ratios can be measured and PSD performance can be quantified. Comparing neutron pulse-height distributions allows for pulse-height specific PSD evaluation, and quantification and visualization of deviation from (CI)-C-252 alone. Even with the addition of the misclassified gamma-rays, the PSD is effective in separating particles so that neutron count rate can be predicted with less than 10% error up to a gamma-to-neutron ratio of almost 650 for applications which can afford a reduction in neutron detection efficiency, PSD can be sufficiently effective in discriminating particles to measure a weak neutron source in a high gamma-ray background.

A design of high-pressure gas cells that are suitable for hydrogen and helium isotopes at relatively high electron beam currents is presented. In particular, we consider rare gas targets, H-3(2) and He-3. In the design, heat transfer and mechanical integrity of the target cell are emphasized.

Since the ultimate goal in this study was to design a gas target for use at the Jefferson Laboratory (JLab), particular attention is given to the typical operating conditions found there. It is demonstrated that an aluminum alloy cell can meet the required design goals. (C) 2013 Elsevier B.V. All rights reserved C1 [Brajuskovic, B.; O'Connor, T.; Holt, R.

TI Implosion chain reaction mitigation in underwater assemblies of photomultiplier tubes SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE PMT; Implosion; Shock wave; Chain reaction ID EXPLOSION AB Since the accident with a cascade failure of photomultiplier tubes (PMTs) in the Super-Kamiokande experiment in 2001, the mechanical performance of large format semi-hemispherical PMTs has become a critical issue for large water Cherenkov detectors. The subject of this study is the survival of an assembled array of PMTs under significant hydrostatic pressure and subjected to shock waves caused by the failure of a single PMT. This paper details the results of the second stage of a R&D program focused on the design and testing of different PMT assemblies to mitigate the risk of a "chain-reaction" of PMT failures. The initial results show that our PMT assembly design can effectively reduce the magnitude of the shock wave. With the testing results in this paper and the hydrodynamic simulation calculation, we can further improve the design of PMT deployment to mitigate the risk of chain reactions caused by implosion induced shock waves.

TI Neutron tomography of particulate filters: a non-destructive investigation tool for applied and industrial research SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Neutron radiography; Iterative reconstruction; Computed tomography; Particulate filters ID SOOT DEPOSITION; RADIOGRAPHY; SIMULATION AB This research describes the development and implementation of high-fidelity neutron imaging and the associated analysis of the images. This advanced capability allows the non-destructive, non-invasive imaging of particulate filters (PFs) and how the deposition of particulate and catalytic washcoat occurs within the filter. The majority of the efforts described here were performed at the High Flux Isotope Reactor (HFIR) CG-1D neutron imaging beamline at Oak Ridge National Laboratory; the current spatial resolution is approximately 50 mu M. The sample holder is equipped with a high-precision rotation stage that allows 3D imaging (i.e., computed tomography) of the sample when combined with computerized reconstruction tools. What enables the neutron-based image is the ability of some elements to absorb or scatter neutrons where other elements allow the neutron to pass through them with negligible interaction. Of particular interest in this study is the scattering of neutrons by hydrogen-containing molecules, such as hydrocarbons (HCs) and/or water, which are adsorbed to the surface of soot, ash and catalytic washcoat. Even so, the interactions with this adsorbed water/HC is low and computational techniques were required to enhance the contrast, primarily a modified simultaneous iterative reconstruction technique (SIRT). This effort describes the following systems: particulate randomly distributed in a PF, ash deposition in PFs, a catalyzed washcoat layer in a PF, and three particulate loadings in a SiC PF.

In this paper, we present accelerator structure and high power rf system designs at three rf (2.856 GHz, 5.712 GHz and 11.424 GHz) that are optimized for single bunch and multi-bunch linac operation with very low beam loading. General scaling laws for the main linac parameters are derived to serve as guidelines to optimize such linacs at other frequencies. The linac costs at the three rf are also discussed. High rf linacs are shown to provide compact, low cost and reasonably efficient drivers for X-ray FELs. Published by Elsevier B.V.

Since the method relies on MCNP for transport calculations, it is easily generalized to most non-destructive evaluation (NDE) simulations. We verify the method's accuracy through ASTM International's E592-99 publication, Standard Guide to Obtainable Equivalent Penetrameter Sensitivity for Radiography of Steel Plates [1]. Potential uses for the method include characterizing alternative radiological sources and simulating NDE radiographs. (C) 2013 Elsevier B.V. All rights reserved.

TI A new fast neutron collar for safeguards inspection measurements of fresh low enriched uranium fuel assemblies containing burnable poison rods SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Neutron counting; Nondestructive assay; Monte Carlo simulation; Fresh fuel assembly; Burnable poison rods; Safeguards AB Safeguards inspection measurements must be performed in a timely manner in order to detect the diversion of significant quantities of nuclear material. A shorter measurement time can increase the number of items that a nuclear safeguards inspector can reliably measure during a period of access to a nuclear facility. In turn, this improves the reliability of the acquired statistical sample, which is used to inform decisions regarding compliance. Safeguards inspection measurements should also maintain independence from facility operator declarations. Existing neutron collars employ thermal neutron interrogation for safeguards inspection measurements of fresh fuel assemblies. A new fast neutron collar has been developed for safeguards inspection measurements of fresh lowenriched uranium (LEU) fuel assemblies containing gadolinia (Gd2O3) burnable poison rods. The Euratom Fast Collar (EFC) was designed with high neutron detection efficiency to make a fast (Cd) mode measurement viable whilst meeting the high counting precision and short assay time requirements of the Euratom safeguards inspectorate. A fast mode measurement reduces the instrument sensitivity to burnable poison rod content and therefore reduces the applied poison correction, consequently reducing the dependence on the operator declaration of the poison content within an assembly. The EFC nondestructive assay (NDA) of typical modern European pressurized water reactor (PWR) fresh fuel assembly designs have been simulated using Monte Carlo N-particle extended transport code (MCNPX) simulations. Simulations predict that the EFC can achieve 2% relative statistical uncertainty on the doubles neutron counting rate for a fast mode measurement in an assay time of GOO s (10 min) with the available (AmLi)-Am-241 (alpha,n) interrogation source strength of 5.7 x 10(4) s(-1). Furthermore, the calibration range of the new collar has been extended to verify U-235 content in variable PWR fuel designs in the presence of up to 32 gadolinia burnable poison rods with Gd concentrations of up to 12 wt%. Monte Carlo calculations predict that the EFC has a lower statistical uncertainty for measurements performed in the fast neutron mode than its predecessor neutron collar design. This paper describes the physics design and calculated performance characteristics of the EEC. The Gd response is presented over a realistic range for modern PWR fuel designs.

Tests conducted with recently developed PSD-capable plastic scintillators showed that incorporation of Li-6 into the aromatic matrix with fast-neutron/gamma discrimination properties offers the additional sensitivity to thermal neutrons, substantially increasing efficiency and the energy range of neutron detection. Comparative analyses of Li-6-loaded plastic, liquid and single crystal organic scintillators provide evidence that, in addition to neutron/gamma discrimination, these novel materials have the ability for discrimination between the signatures of fast and thermal neutrons.

Fringe fields from the kaon spectrometer magnet yielded similar to 5 gauss at the photomultiplier tubes for these detectors. These fields, which could not be easily passively shielded, would result in a lowered kaon detection efficiency if not mitigated. A bucking coil was placed on each photomultiplier tube to actively cancel this magnetic field, thus recovering kaon detection efficiency. (C) 2013 Elsevier B.V.

These particles are created in cascades, caused by upstream interactions of beam protons with residual gas molecules or collimators. We estimate the losses On the collimators with SixTrack and simulate the showers with FLUKA and MARS to obtain the flux and distribution of particles entering the ATLAS and CMS detectors. We consider some machine configurations used in the first LHC run, with focus on 3.5 TeV operation as in 2011. Results from FLUKA and MARS are compared and a very good agreement is found. An analysis of logged LHC data provides, for different processes, absolute beam loss rates, which are used together with further simulations of vacuum conditions to normalize the results to rates of particles entering the detectors. We assess the relative importance of background from elastic and inelastic beam-gas interactions, and the leakage out of the LHC collimation system, and show that beam-gas interactions are the dominating source of machine-induced background for the studied machine scenarios. Our results serve as a starting point for the experiments to perform further simulations in order to estimate the resulting signals in the detectors. (C) 2013 Elsevier B.V.

As such, they are promising feedstocks for the production of biofuels and bioproducts. Genetic strain-engineering strategies offer a means to accelerate the commercialization of algal biofuels by improving the rate and total accumulation of microalgal lipids. However, the industrial potential of these organisms remains to be met, largely due to the incomplete knowledgebase surrounding the mechanisms governing the induction of algal lipid biosynthesis. Such strategies require further elucidation of genes and gene products controlling algal lipid accumulation. In this study, we have set out to examine these mechanisms and identify novel strain-engineering targets in the oleaginous microalga, Chlorella vulgaris. Comparative shotgun proteomic analyses have identified a number of novel targets, including previously unidentified transcription factors and proteins involved in cell signaling and cell cycle regulation. These results lay the foundation for strain-improvement strategies and demonstrate the power of translational proteomic analysis. Biological significance We have applied label-free, comparative shotgun proteomic analyses, via a transcriptome-to-proteome pipeline, in order to examine the nitrogen deprivation response in the oleaginous microalga, C. vulgaris. Herein, we identify potential targets for strain-engineering strategies targeting enhanced lipid accumulation for algal biofuels applications. Among the identified targets are proteins involved in transcriptional regulation, lipid biosynthesis, cell signaling and cell cycle progression.

TI Comparing Bacterial Community Composition between Healthy and White Plague-Like Disease States in Orbicella annularis Using PhyloChip (TM) G3 Microarrays SO PLOS ONE LA English DT Article ID BLACK BAND DISEASE; CORAL MUSSISMILIA-BRAZILIENSIS; SIDERASTREA-SIDEREA; MICROBIAL ECOLOGY; ACROPORA-PALMATA; CAUSATIVE AGENT; ELKHORN CORAL; REEF; DIVERSITY; CULTURE AB Coral disease is a global problem. Diseases are typically named or described based on macroscopic changes, but broad signs of coral distress such as tissue loss or discoloration are unlikely to be specific to a particular pathogen. For example there appear to be multiple diseases that manifest the rapid tissue loss that characterizes 'white plague'. PhyloChip (TM) G3 microarrays were used to compare the bacterial community composition of both healthy and white plague-like diseased corals. Samples of lobed star coral (Orbicella annularis, formerly of the genus Montastraea [1]) were collected from two geographically distinct areas, Dry Tortugas National Park and Virgin Islands National Park, to determine if there were biogeographic differences between the diseases. In fact, all diseased samples clustered together, however there was no consistent link to Aurantimonas coralicida, which has been disease as the causative agent of white plague type II. The microarrays revealed a large amount of bacterial heterogeneity within the healthy corals and less diversity in the diseased corals Gram-positive bacterial groups (Actinobacteria, Firmicutes) comprised a greater proportion of the operational taxonomic units (OTUs) unique to healthy samples. Diseased samples were enriched in OTUs from the families Corynebacteriacea, Lachnospiracea, Rhodobacteraceae, and Streptococcaceae. Much previous coral disease work has used clone libraries, which seem to be methodologically biased toward recovery of Gram-negative bacterial sequences and may therefore have missed the importance of Gram-positive groups. The Phylochip (TM) data presented here provide a broader characterization of the bacterial community changes that occur within Orbicella annularis during the shift from a healthy to diseased state.

In an effort to tune and enhance their properties in a systematic manner we have applied a designing strategy to deliberately introduce organic linker molecules in these perovskite-like crystal lattices. This approach has led to a wealth of new hybrid structures built on one-dimensional (1D) and two-dimensional (2D) VI-VI modules. The hybrid semiconductors exhibit a number of greatly improved properties and new functionality, including broad band gap tunability, negative thermal expansion, largely reduced thermal conductivity, and significantly enhanced dielectric constant compared to their MO3 parent phases.

TI L-Edge X-ray Absorption Spectroscopy and DFT Calculations on Cu2O2 Species: Direct Electrophilic Aromatic Attack by Side-on Peroxo Bridged Dicopper(II) Complexes SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID DINUCLEAR COPPER(I) COMPLEXES; REVERSIBLE DIOXYGEN BINDING; MONOOXYGENASE MODEL SYSTEM; CORRELATION-ENERGY; ACTIVE-SITE; BIS(MU-OXO)DICOPPER(III) COMPLEX; ELECTRONIC-STRUCTURES; BOND ORDER; CU-II; REACTIVITY AB The hydroxylation of aromatic substrates catalyzed by coupled binuclear copper enzymes has been observed with side-on-peroxo-dicopper(H) (P) and bis-mu-oxo-dicopper(III) (0) model complexes. The substrate-bound-O intermediate in [Cu(II)(2)(DBED)(2)(O)(2)](2+) (DBED = N,N'-di-tert-butyl-ethylenediamine) was shown to perform aromatic hydroxylation. For the [Cu(II)(2)(NO2-XYL)(O-2)](2+) complex, only a P species was spectroscopically observed. However, it was not clear whether this O-O bond cleaves to proceed through an O-type structure along the reaction coordinate for hydroxylation of the aromatic xylyl linker. Accurate evaluation of these reaction coordinates requires reasonable quantitative descriptions of the electronic structures of the P and O species. We have performed Cu L-edge XAS on two well-characterized P and O species to experimentally quantify the Cu 3d character in their ground state wave functions. The lower per-hole Cu character (40 +/- 6%) corresponding to higher covalency in the O species compared to the P species (52 +/- 4%) reflects a stronger bonding interaction of the bis-mu-oxo core with the Cu(III) centers. DFT calculations show that 10-20% Hartree-Fock (HF) mixing for P and similar to 38% for O species are required to reproduce the Cu-O bonding; for the P species this HF mixing is also required for an antiferromagnetically coupled description of the two Cu(II) centers. B3LYP (with 20% HF) was, therefore, used to calculate the hydroxylation reaction coordinate of P in [Cu(II)(2)(NO2-XYL)(O-2)](2+). These experimentally calibrated calculations indicate that the electrophilic attack on the aromatic ring does not involve formation of a Cu(III)(2)(O2-)(2) species. Rather, there is direct electron donation from the aromatic ring into the peroxo sigma* orbital of the Cu(II)(2)(O-2(2-)) species, leading to concerted C-O bond formation with O-O bond cleavage. Thus, species P is capable of direct hydroxylation of aromatic substrates without the intermediacy of an O-type species. C1 [Qayyum, Munzarin F.; Stack, T.

TI Toroidal Structure and DNA Cleavage by the CRISPR-Associated [4Fe-4S] Cluster Containing Cas4 Nuclease SSO0001 from Sulfolobus solfataricus SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID CRYSTAL-STRUCTURE; ESCHERICHIA-COLI; LAMBDA-EXONUCLEASE; IMMUNE-SYSTEMS; PROKARYOTES; COMPLEX; MECHANISM; ENZYME; BACTERIOPHAGE; ENDONUCLEASE AB Cas4 proteins, a core protein family associated with the microbial system of adaptive immunity CRISPR, are predicted to function in the adaptation step of the CRISPR mechanism. Here we show that the Cas4 protein SSO0001 from the archaeon Sulfolobus solfataricus has metal-dependent endonuclease and 5'-> 3' exonuclease activities against single-stranded DNA, as well as ATP-independent DNA unwinding activity toward double-stranded DNA. The crystal structure of SSO0001 revealed a decameric toroid formed by five dimers with each protomer containing one [4Fe-4S] cluster and one Mn2+ ion bound in the active site located inside the internal tunnel. The conserved RecB motif and four Cys residues are important for DNA binding and cleavage activities, whereas DNA unwinding depends on several residues located near the [4Fe-4S] cluster. Our results suggest that Cas4 proteins might contribute to the addition of novel CRISPR spacers through the formation of 3'-DNA overhangs and to the degradation of foreign DNA.

TI Geometric and Electronic Structure of the Mn(IV)Fe(III) Cofactor in Class Ic Ribonucleotide Reductase: Correlation to the Class la Binuclear Non-Heme Iron Enzyme SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID RESONANCE VIBRATIONAL SPECTROSCOPY; DENSITY-FUNCTIONAL THEORY; TYROSYL RADICAL-DIIRON(III) COFACTOR; PROTONATED OXYGENIC LIGANDS; ATOMIC SCREENING CONSTANTS; CHLAMYDIA-TRACHOMATIS; INTERMEDIATE-X; MANGANESE(IV)/IRON(III) COFACTOR; MODEL COMPLEXES; DIIRON CLUSTER AB The class Ic ribonucleotide reductase (RNR) from Chlamydia trachomatis (Ct) utilizes a Mn/Fe hetero-binuclear cofactor, rather than the Fe/Fe cofactor found in the beta (R2) subunit of the class Ia enzymes, to react with O-2. This reaction produces a stable (MnFeIII)-Fe-IV cofactor that initiates a radical, which transfers to the adjacent alpha (R1) subunit and reacts with the substrate. We have studied the (MnFeIII)-Fe-IV cofactor using nuclear resonance vibrational spectroscopy (NRVS) and absorption (Abs)/circular dichroism (CD)/magnetic CD (MCD)/variable temperature, variable field (VTVH) MCD spectroscopies to obtain detailed insight into its geometric/electronic structure and to correlate structure with reactivity; NRVS focuses on the Fe-III, whereas MCD reflects the spin-allowed transitions mostly on the Mn-IV. We have evaluated 18 systematically varied structures. Comparison of the simulated NRVS spectra to the experimental data shows that the cofactor has one carboxylate bridge, with Mn-IV at the site proximal to Phe(127). Abs/CD/MCD/VTVH MCD data exhibit 12 transitions that are assigned as d-d and oxo and OH- to metal charge-transfer (CT) transitions. Assignments are based on MCD/Abs intensity ratios, transition energies, polarizations, and derivative-shaped pseudo-A term CT transitions. Correlating these results with TD-DFT calculations defines the (MnFeIII)-Fe-IV cofactor as having a mu-oxo, mu-hydroxo core and a terminal hydroxo ligand on the Mn-IV. From DFT calculations, the Mn-IV at site 1 is necessary to tune the redox potential to a value similar to that of the tyrosine radical in class La RNR, and the OH- terminal ligand on this Mn-IV provides a high proton affinity that could gate radical translocation to the alpha (R1) subunit.

TI Characterization of four potential laser-induced fluorescence tracers for diesel engine applications SO APPLIED OPTICS LA English DT Article ID 2-COLOR TOLUENE-LIF; TEMPERATURE-MEASUREMENTS; ELEVATED-TEMPERATURES; FUEL CONCENTRATION; COMBUSTION; VAPOR; MIXTURE; SYSTEMS; ALKANE; RATIO AB Four potential laser-induced fluorescence (LIF) tracers, 1-phenyloctane, 1-phenyldecane, 1-methylnaphthalene, and 2-methylnaphthalene, are characterized for diesel engine applications. These tracers, embedded in the diesel primary reference fuels n-C16H34 and iso-C16H34, match the relevant physical properties of commercial diesel fuel much better than the commonly used toluene/iso-octane/n-heptane tracer-fuel system does. The temperature and pressure dependencies of the fluorescence intensities and spectra were measured in a flow cell in nitrogen for each candidate tracer molecule. The results show that the signal intensities of the methylnaphthalenes are about two orders of magnitude higher than for 1-phenyloctane and 1-phenyldecane and show a strong temperature but no pressure, dependence. An analysis of the fluorescence spectrum of 1-methylnaphthalene shows that it also can be used for two-color detection LIF thermometry by choosing appropriate optical filters.

TI HIGHLY CONCENTRATED NEBULAR NOBLE GASES IN POROUS NANOCARBON SEPARATES FROM THE SARATOV (L4) METEORITE SO ASTROPHYSICAL JOURNAL LA English DT Article DE meteorites; meteors; meteoroids ID LABORATORY SIMULATION; PHASE-Q; PRIMITIVE CHONDRITES; ALLENDE METEORITE; XENON; CARBON; SORPTION; ADSORPTION; COMPONENT; GRAPHITE AB The majority of heavy noble gases (Ar, Kr, and Xe) in primitive meteorites are stored in a poorly understood phase called Q. Although Q is thought to be carbonaceous, the full identity of the phase has remained elusive for almost four decades. In order to better characterize phase Q and, in turn, the early solar nebula, we separated carbon-rich fractions from the Saratov (L4) meteorite. We chose this meteorite because Q is most resistant in thermal alteration among carbonaceous noble gas carriers in meteorites and we hoped that, in this highly metamorphosed meteorite, Q would be present but not diamond: these two phases are very difficult to separate from each other. One of the fractions, AJ, has the highest Xe-132 concentration of 2.1 x 10(-6) cm(3) STP g(-1), exceeding any Q-rich fractions that have yet been analyzed. Transmission electron microscopy studies of the fraction AJ and a less Q-rich fraction AI indicate that they both are primarily porous carbon that consists of domains with short-range graphene orders, with variable packing in three dimensions, but no long-range graphitic order. The relative abundance of Xe and C atoms (6:10(9)) in the separates indicates that individual noble gas atoms are associated with only a minor component of the porous carbon, possibly one or more specific arrangements of the nanoparticulate graphene.

We apply a nested-grid technique to resolve the thermodynamics of the disk at the orbital-radius length scale and that of the envelope at the core-radius length scale. The gas is modeled as a solar mixture of molecular and atomic hydrogen, helium, and their ions. The equation of state accounts for both gas and radiation, and gas energy includes contributions from rotational and vibrational states of molecular hydrogen and from ionization of atomic species. Dust opacities are computed from first principles, applying the full Mie theory. One-dimensional (1D) calculations of planet formation are used to supplement the 3D calculations by providing energy deposition rates in the envelope due to solids accretion. We compare 1D and 3D envelopes and find that masses and gas accretion rates agree within factors of 2, and so do envelope temperatures. The trajectories of passive tracers are used to define the size of 3D envelopes, resulting in radii much smaller than the Hill radius and smaller than the Bondi radius. The moments of inertia and angular momentum of the envelopes are determined and the rotation rates are derived from the rigid-body approximation, resulting in slow bulk rotation. We find that the polar flattening is less than or similar to 0.05. The dynamics of the accretion flow are examined by tracking the motion of tracers that move into the envelope. The anisotropy of this flow is characterized in terms of both its origin and impact site at the envelope surface. Gas merges with the envelope preferentially at mid- to high latitudes.

They are also the first signals to arrive from a supernova (SN) and, if detected, establish the moment when the shock wave is formed that unbinds the stellar envelope and later initiates the optical display upon reaching the stellar surface with a burst of UV and X-ray photons, the shock breakout (SBO). We discuss how neutrino observations can be used to trigger searches to detect the elusive SBO event. Observation of the SBO would provide several important constraints on progenitor structure and the explosion, including the shock propagation time (the duration between the neutrino burst and SBO), an observable that is important in distinguishing progenitor types. Our estimates suggest that next-generation neutrino detectors could exploit the overdensity of nearby SNe to provide several such triggers per decade, more than an order-of-magnitude improvement over the present.

Outflows, which have been observed around a variety of galaxies, can provide this influence in such a way as to collapse, rather than disperse, the minihalo gas. Gray & Scannapieco performed an investigation in which idealized spherically symmetric minihalos were struck by enriched outflows. Here we perform high-resolution cosmological simulations that form realistic minihalos, which we then extract to perform a large suite of simulations of outflow-minihalo interactions including non-equilibrium chemical reactions. In all models, the shocked minihalo forms molecules through non-equilibrium reaction, and then cools to form dense, chemically homogenous clumps of star-forming gas. The formation of these high-redshift clusters may be observable with the next generation of telescopes and the largest of them should survive to the present-day, having properties similar to halo globular clusters.

TI SUPERMASSIVE POPULATION III SUPERNOVAE AND THE BIRTH OF THE FIRST QUASARS SO ASTROPHYSICAL JOURNAL LA English DT Article DE black hole physics; cosmology: theory; early universe; galaxies: formation; galaxies: high-redshift; hydrodynamics; radiative transfer; stars: early-type; supernovae: general ID PAIR-INSTABILITY SUPERNOVAE; BLACK-HOLE FORMATION; METAL-POOR STARS; GAMMA-RAY BURST; MASSIVE PRIMORDIAL STARS; HIGH-REDSHIFT UNIVERSE; DARK-MATTER HALOES; DIRECT COLLAPSE; HII REGION; PROTOSTELLAR FEEDBACK AB The existence of supermassive black holes as early as z similar to 7 is one of the great, unsolved problems in cosmological structure formation. One leading theory argues that they are born during catastrophic baryon collapse in z similar to 15 protogalaxies that form in strong Lyman-Werner UV backgrounds. Atomic line cooling in such galaxies fragments baryons into massive clumps that are thought to directly collapse to 10(4)-10(5) M-circle dot black holes. We have now discovered that some of these fragments can instead become supermassive stars that eventually explode as thermonuclear supernovae (SNe) with energies of similar to 10(55) erg, the most energetic explosions in the universe. We have calculated light curves and spectra for supermassive Pop III SNe with the Los Alamos RAGE and SPECTRUM codes. We find that they will be visible in near-infrared all-sky surveys by Euclid out to z similar to 10-15 and by WFIRST and WISH out to z similar to 15-20, perhaps revealing the birthplaces of the first quasars.

Combined with a prediscovery detection by the Italian Supernova Search Project, we are able to constrain the first-light time of SN 2013dy to be only 0.10 +/- 0.05 days (2.4 +/- 1.2 hr) before the first detection. This makes SN 2013dy the earliest known detection of an SN Ia. We infer an upper limit on the radius of the progenitor star of R-0 less than or similar to 0.25 R-circle dot, consistent with that of a white dwarf. The light curve exhibits a broken power law with exponents of 0.88 and then 1.80. A spectrum taken 1.63 days after first light reveals a C II absorption line comparable in strength to Si II. This is the strongest C II feature ever detected in a normal SN Ia, suggesting that the progenitor star had significant unburned material. The C II line in SN 2013dy weakens rapidly and is undetected in a spectrum 7 days later, indicating that C II is detectable for only a very short time in some SNe Ia. SN 2013dy reached a B-band maximum of M-B = -18.72 +/- 0.03 mag similar to 17.7 days after first light.

TI Detecting small plant peptides using SPADA (Small Peptide Alignment Discovery Application) SO BMC BIOINFORMATICS LA English DT Article DE Protein family; Genome annotation; Homology search; Gene prediction ID MULTIPLE SEQUENCE ALIGNMENTS; GENE STRUCTURE PREDICTION; GENOME; ARABIDOPSIS; DATABASE; EXPRESSION; FAMILIES; ANNOTATION; GENERATION; SYMBIOSIS AB Background: Small peptides encoded as one- or two-exon genes in plants have recently been shown to affect multiple aspects of plant development, reproduction and defense responses. However, popular similarity search tools and gene prediction techniques generally fail to identify most members belonging to this class of genes. This is largely due to the high sequence divergence among family members and the limited availability of experimentally verified small peptides to use as training sets for homology search and ab initio prediction. Consequently, there is an urgent need for both experimental and computational studies in order to further advance the accurate prediction of small peptides. Results: We present here a homology-based gene prediction program to accurately predict small peptides at the genome level. Given a high-quality profile alignment, SPADA identifies and annotates nearly all family members in tested genomes with better performance than all general-purpose gene prediction programs surveyed. We find numerous mis-annotations in the current Arabidopsis thaliana and Medicago truncatula genome databases using SPADA, most of which have RNA-Seq expression support. We also show that SPADA works well on other classes of small secreted peptides in plants (e.g., self-incompatibility protein homologues) as well as non-secreted peptides outside the plant kingdom (e.g., the alpha-amanitin toxin gene family in the mushroom, Amanita bisporigera). Conclusions: SPADA is a free software tool that accurately identifies and predicts the gene structure for short peptides with one or two exons. SPADA is able to incorporate information from profile alignments into the model prediction process and makes use of it to score different candidate models. SPADA achieves high sensitivity and specificity in predicting small plant peptides such as the cysteine-rich peptide families. A systematic application of SPADA to other classes of small peptides by research communities will greatly improve the genome annotation of different protein families in public genome databases.

TI Frontotemporal Network Connectivity during Memory Encoding Is Increased with Aging and Disrupted by Beta-Amyloid SO JOURNAL OF NEUROSCIENCE LA English DT Article ID AGE-RELATED DIFFERENCES; INTRINSIC FUNCTIONAL CONNECTIVITY; MILD COGNITIVE IMPAIRMENT; NORMAL OLDER-ADULTS; ALZHEIMERS-DISEASE; RECOGNITION MEMORY; DEFAULT NETWORK; BRAIN ACTIVITY; APOLIPOPROTEIN-E; MOUSE MODEL AB Approximately 30% of cognitively normal older adults harbor brain beta-amyloid (A beta), a prominent feature of Alzheimer's disease associated with neural alterations and episodic memory decline. We examined how aging and A beta deposition affect neural function during memory encoding of visual scenes using functional magnetic resonance imaging (fMRI) in humans. Thirty-six cognitively normal older people underwent fMRI scanning, and positron emission tomography with [C-11] Pittsburgh compound B to measure fibrillar brain A beta; 15 young subjects were studied with fMRI. Older adults without A beta deposition showed reduced regional brain activation (compared with young subjects) with decreased task-independent functional connectivity between parahippocampal gyrus and prefrontal cortex. In this network, task-related connectivity was increased compared with young subjects, and the degree of connectivity was related to memory performance. In contrast, older individuals with A beta deposition showed no such increased task-related network connectivity, but did display increased regional activity unassociated with performance. These findings suggest that network connectivity plays a significant role in compensating for reduced regional activity during successful memory encoding in aging without A beta deposition, while in those with A beta this network compensation fails and is accompanied by inefficient regional hyperactivation.

TI Altered magnetism and new electronic length scales in magneto-electric La2/3Sr1/3MnO3-BiFeO3 heterointerface SO NEW JOURNAL OF PHYSICS LA English DT Article ID INTERFACE; OXIDES AB We map out the charge-spin density profile of magneto-electric La2/3Sr1/3MnO3 (LSMO)-BiFeO3 (BFO) heterostructure using soft x-ray resonant magnetic reflectivity. We show that the spatial extent of interface orbitals can extend over a few lattice periods even for an atomically sharp interface. While LSMO magnetization is depleted at the interface, BFO does develop a weak magnetic moment mostly near the interface, probably due to a proximity-induced charge-transfer process. Our study reveals that simultaneous control of electronic and magnetic interfaces is essential in realizing the potential of oxide devices. C1 [Mishra, S. K.; Kevan, S.

CA PHENIX Collaboration TI Quadrupole Anisotropy in Dihadron Azimuthal Correlations in Central d plus Au Collisions at root s(NN)=200 GeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID ANGULAR-CORRELATIONS; PB COLLISIONS; LONG-RANGE; PARTON; SIDE; TEV AB The PHENIX collaboration at the Relativistic Heavy Ion Collider (RHIC) reports measurements of azimuthal dihadron correlations near midrapidity in d + Au collisions at root s(NN) = 200 GeV. These measurements complement recent analyses by experiments at the Large Hadron Collider (LHC) involving central p + Pb collisions at root s(NN) = 5.02 TeV, which have indicated strong anisotropic long-range correlations in angular distributions of hadron pairs. The origin of these anisotropies is currently unknown. Various competing explanations include parton saturation and hydrodynamic flow. We observe qualitatively similar, but larger, anisotropies in d + Au collisions at RHIC compared to those seen in p + Pb collisions at the LHC. The larger extracted upsilon(2) values in d + Au are consistent with expectations from hydrodynamic calculations owing to the larger expected initial-state eccentricity compared with that from p + Pb collisions. When both are divided by an estimate of the initial-state eccentricity the scaled anisotropies follow a common trend with multiplicity that may extend to heavy ion data at RHIC and the LHC, where the anisotropies are widely thought to arise from hydrodynamic flow.

However, the reversible control of H density (n(H) ) on graphene is difficult due to the irreversible H-2 formation of the detached H adatoms. Here we present a novel mechanism for controlling n(H) by using the unique proton transfer reaction between NH3 gas and hydrogenated graphene, which can be tuned by applying perpendicular electric fields. Using first-principles calculations, we show that n(H) can be reversibly tuned by the applied electric fields around the critical density for the Anderson localization in hydrogenated graphene. The proposed field-induced control of H adsorption or desorption on graphene opens a path toward the development of new graphene transistors based on the tunable degree of disorder.

We show that monolayer MoS2 possesses a large and diverse number of strongly bound excitonic states with novel k-space characteristics that were not previously seen experimentally or theoretically. The absorption spectrum is shown to be dominated by excitonic states with a binding energy close to 1 eV and by strong electron-phonon broadening in the visible to ultraviolet range.

TI The Wiedemann-Franz law in the putative one-dimensional metallic phase of PrBa2Cu4O8 SO SCIENTIFIC REPORTS LA English DT Article ID LUTTINGER LIQUID; THERMAL TRANSPORT; DOUBLE CHAINS; SYSTEMS; CONDUCTIVITY; FERMI; RESISTIVITY; CU AB The nature of the electronic state of a metal depends strongly on its dimensionality. In a system of isolated conducting chains, the Fermi-liquid (quasiparticle) description appropriate for higher dimensions is replaced by the so-called Tomonaga-Luttinger liquid picture characterized by collective excitations of spin and charge. Temperature is often regarded as a viable tuning parameter between states of different dimensionality, but what happens once thermal broadening becomes comparable to the interchain hopping energy remains an unresolved issue, one that is central to many organic and inorganic conductors. Here we use the ratio of the thermal to electrical conductivities to probe the nature of the electronic state in PrBa2Cu4O8 as a function of temperature. We find that despite the interchain transport becoming non-metallic, the charge carriers within the CuO chains appear to retain their quasiparticle nature. This implies that temperature alone cannot induce a crossover from Fermi-liquid to Tomonaga-Luttinger-liquid behaviour in quasi-one-dimensional metals. C1 [Bangura, A.

In this report, we present estimates of inorganic carbon turnover rates determined from laboratory incubations of Holothuria afro, Holothuria leucospilota and Stichopus herrmanni. The pH values of the gut lumen ranged from 7.0 to 7.6 when digestive tracts were filled with sediment compared with 6.1-6.7 in animals with empty digestive tracts. Empty gut volume estimates for H. afro and S. he; tmanni were 36 4 mL and 151 14 ml, respectively. Based on these measurements and the density and porosity of carbonate sediments of coral reefs, it is estimated that these species process 19 2 kg and 80 7 kg CaCO3 sand yr-1 per individual, respectively. The annual CaCO3 dissolution rates per H. aria and S. hei ',Lanni individual are estimated to be 6.5 1.9 g and 9.6 1.4 g, respectively, suggesting that 0.05 0.02% and 0.1 0.02% of the CaCO3 processed through their gut annually is dissolved. During incubations the CaCO3 dissolution of the fecal casts was 0.07 0.01%, 0.04 0.01% and 0.21 0.05% for H. aria, H. leucospilota and S. herrmanni, respectively. The CaCO3 saturation state in the incubation seawater decreased markedly due to a greater increase in dissolved inorganic carbon (DIC) relative to total alkalinity (AT) as a result of respiration by the animals. Our results support the hypothesis that deposit feeders such as sea cucumbers play an important ecological role in the coral reef CaCO3 cycle. (C) 2013 Elsevier Ltd. All rights reserved.

TI Alternating absorption features during attosecond-pulse propagation in a laser-controlled gaseous medium SO PHYSICAL REVIEW A LA English DT Article ID INDUCED TRANSPARENCY; STATES; HELIUM; LIGHT AB Recording the transmitted spectrum of a weak attosecond pulse through a medium, while a strong femtosecond pulse copropagates at variable delay, probes the strong-field dynamics of atoms, molecules, and solids. Usually, the interpretation of these measurements is based on the assumption of a thin medium. Here, the propagation through a macroscopic medium of helium atoms in the region of fully allowed resonances is investigated both theoretically and experimentally. The propagation has dramatic effects on the transient spectrum even at relatively low pressures (50 mbar) and short propagation lengths (1 mm). The absorption does not evolve monotonically with the product of propagation distance and pressure, but regions with characteristics of Lorentz line shapes and characteristics of Fano line shapes alternate. Criteria are deduced to estimate whether macroscopic effects can be neglected or not in a transient absorption experiment. Furthermore, the theory in the limit of single-atom response yields a general equation for Lorentz- and Fano-type line shapes at variable pulse delay. C1 [Pfeiffer, Adrian N.; Bell, M.

The order-parameter critical exponent is found to be very close to its value beta = 0.5 expected for magnetic Bose-Einstein condensation in the absence of disorder. This result applies to temperatures down to 40 mK, and a 1 T range in magnetic field. The crossover exponent is found to be phi similar to 0.4 for temperature ranges as small as 300 mK.

TI Low intensity conduction states in FeS2: implications for absorption, open-circuit voltage and surface recombination SO JOURNAL OF PHYSICS-CONDENSED MATTER LA English DT Article ID DENSITY-FUNCTIONAL THEORY; IRON PYRITE FES2; AUGMENTED-WAVE METHOD; ELECTRONIC-STRUCTURE; OPTICAL-PROPERTIES; NATURAL PYRITE; BAND-GAP; SPECTRA; INSULATORS; BULK AB Pyrite (FeS2), being a promising material for future solar technologies, has so far exhibited in experiments an open-circuit voltage (OCV) of around 0.2 V, which is much lower than the frequently quoted 'accepted' value for the fundamental bandgap of similar to 0.95 eV. Absorption experiments show large subgap absorption, commonly attributed to defects or structural disorder. However, computations using density functional theory with a semi-local functional predict that the bottom of the conduction band consists of a very low intensity sulfur p-band that may be easily overlooked in experiments because of the high intensity onset that appears 0.5 eV higher in energy. The intensity of absorption into the sulfur p-band is found to be of the same magnitude as contributions from defects and disorder. Our findings suggest the need to re-examine the value of the fundamental bandgap of pyrite presently in use in the literature. If the contribution from the p-band has so far been overlooked, the substantially lowered bandgap would partly explain the discrepancy with the OCV. Furthermore, we show that more states appear on the surface within the low energy sulfur p-band, which suggests a mechanism of thermalization into those states that would further prevent extracting electrons at higher energy levels through the surface. Finally, we speculate on whether misidentified states at the conduction band onset may be present in other materials. C1 [Lazic, P.; Herbert, F.

TI Density of states features in some anomalous melting elements SO JOURNAL OF PHYSICS-CONDENSED MATTER LA English DT Article ID TEMPERATURE HEAT-CAPACITIES; ELECTRONIC-STRUCTURE; GALLIUM; PHOTOEMISSION; INDIUM; METALS; TRANSITION AB Valence band photoemission measurements have been made on crystalline and supercooled liquid gallium, and across the liquid and solid phases of bismuth and indium. Measurements are angle integrated and made using photon excitations of 21.21 and 40.81 eV. In all cases the Bloch states are destroyed upon melting and the free electron gas is constrained by a charge-neutral liquid. The spectra of indium show little change upon solidification, indicating a common electronic structure for crystalline and liquid phases. In contrast, the energy distribution curves for supercooled gallium and bismuth show large changes in the electronic structure from solid to liquid phases, giving rise to the formation of pseudogaps in the density of states at the Fermi energy, E-F. Observations of this kind enable us to distinguish normal or anomalous melting from photoemission measurements. C1 [Schulze, R. K.; Wallace, D. C.; Lashley, J.

Theoretically, the phase-space analytical results of the automatic system of the equation of state (Los) parameter omega(d) and its evolution w(d)' show a scaling solution F-M appears in the interacting case which hints a possibility of alleviating the "coincidence" problem.

The nature, quantification, and spatial distribution of uranium-bearing phases were investigated by chemical and mineralogical analyses, fission track mapping, electron microscopy, and X-ray absorption near edge structure ()CANES) and extended X-ray absorption fine structure (EXAFS) spectroscopies at the U L-III-edge and Fe K-edge. In addition to uranium-containing phases from the ore, uranium is mostly associated with iron-bearing minerals in all tailing sites. XANES and EXAFS data and transmission electron microscopy analyses of the samples with the highest uranium concentrations (similar to 400-700 mg kg(-1) of U) demonstrate that uranium primarily occurs as monomeric uranyl ions (UO22+), forming inner-sphere surface complexes bound to ferrihydrite (50-70% of the total U) and to a lesser extent to chlorite (30-40% of the total U). Thus, the stability and mobility of uranium at the Gunnar site are mainly influenced by sorption/desorption processes. In this context, acidic pH or alkaline pH with the presence of UO22+- and/or Fe3+-complexing agents (e.g., carbonate) could potentially solubilize U in the tailings pore waters.

However, reactions between dissolved aqueous elemental mercury (Hg(0)(aq)) and organic ligands in general, and thiol compounds in particular, are not well studied although these reactions likely affect Hg speciation and cycling in the environment. In this study, we compared the reaction rates between Hg(0)(aq) and a number of selected organic ligands with varying molecular structures and sulfur (S) oxidation states in dark, anoxic conditions to assess the role of these ligands in Hg(0)(aq) oxidation. Significant Hg(0)(aq) oxidation was observed with all thiols but not with ligands containing no S. Compounds with oxidized S (e.g., disulfide) exhibited little or no reactivity toward Hg(0)(aq) either at pH 7. The rate and extent of Hg(0)(aq) oxidation varied greatly depending on the chemical and structural properties of thiols, thiol/Hg ratios, and the presence or absence of electron acceptors. Smaller aliphatic thiols and higher thiol/Hg ratios resulted in higher Hg(0)(aq) oxidation rates than larger aromatic thiols at lower thiol/Hg ratios. The addition of electron acceptors (e.g., humic acid) also led to substantially increased Hg(0)(aq) oxidation. Our results suggest that thiol-induced oxidation of Hg(0)(aq) is important under anoxic conditions and can affect Hg redox transformation and bioavailability for microbial methylation.

To assess determinants of variability in air pollutant concentrations, we develop land use regression (LUR) models for fine particulate matter (PM2.5), black carbon (BC), and ultrafine particle number concentrations (UFPN). We used 136 h (39 sites), 112 h (26 sites), 147 h (39 sites) of PM2.5, BC, and UFPN data respectively, to develop separate morning (0800-1200) and afternoon (1200-1800) models. Continuous measurements of PM2.5 and BC were also made at a single fixed rooftop site located in a high-income residential neighborhood. No continuous measurements of UFPN were available. In addition to spatial variables, measurements from the fixed continuous monitoring site were used as independent variables in the PM2.5 and BC models. The median concentrations (and interquartile range) of PM2.5, BC, and UFPN at LUR sites were 133 (96-232) mu g m(-3), 11 (6-21) mu g m(-3), and 40 (27-72) X 10(3) cm(-3) respectively. In addition (a) for PM2.5 and BC, the temporal variability was higher than the spatial variability; (b) the magnitude and spatial variability in pollutant concentrations was higher during morning than during afternoon hours. Further, model R-2 values were higher for morning (for PM2.5, BC, and UFPN, respectively: 0.85, 0.86, and 0.28) than for afternoon models (0.73, 0.69, and 0.23); (c) the PM2.5 and BC concentrations measured at LUR sites all over the city were strongly correlated with measured concentrations at a fixed rooftop site; (d) spatial patterns were similar for PM2.5 and BC but different for UFPN; (e) population density and road variables were statistically significant predictors of pollutant concentrations; and (f) available geographic predictors explained a much lower proportion of variability in measured PM2.5, BC, and UFPN than observed in other LUR studies, indicating the importance of temporal variability and suggesting the existence of uncharacterized sources.

The impacts of future environmental change and bioenergy harvests on regional forest carbon storage have not been quantified. We conducted a comprehensive modeling study and life-cycle assessment of the impacts of projected changes in climate, CO2 concentration, and N deposition, and region-wide forest management policies on regional forest carbon fluxes. By 2100, if current management strategies continue, then the warming and CO2 fertilization effect in the given projections result in a 32-68% increase in net carbon uptake, overshadowing increased carbon emissions from projected increases in fire activity and other forest disturbance factors. To test the response to new harvesting strategies, repeated thinnings were applied in areas susceptible to fire to reduce mortality, and two clear-cut rotations were applied in productive forests to provide biomass for wood products and bioenergy. The management strategies examined here lead to long-term increased carbon emissions over current harvesting practices, although semiarid regions contribute little to the increase. The harvest rates were unsustainable. This comprehensive approach could serve as a foundation for regional place-based assessments of management effects on future carbon sequestration by forests in other locations.

TI Microbial Community Changes in Hydraulic Fracturing Fluids and Produced Water from Shale Gas Extraction SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID SP-NOV; BACTERIAL COMMUNITIES; BARNETT SHALE; GEN-NOV; OIL-FIELD; DIVERSITY; WELLS; ENVIRONMENTS; RESISTANCE; TEXAS AB Microbial communities associated with produced water from hydraulic fracturing are not well understood, and their deleterious activity can lead to significant increases in production costs and adverse environmental impacts. In this study, we compared the microbial ecology in prefracturing fluids (fracturing source water and fracturing fluid) and produced water at multiple time points from a natural gas well in southwestern Pennsylvania using 16S rRNA gene-based clone libraries, pyrosequencing, and quantitative PCR. The majority of the bacterial community in prefracturing fluids constituted aerobic species affiliated with the class Alphaproteobacteria. However, their relative abundance decreased in produced water with an increase in halotolerant, anaerobic/facultative anaerobic species affiliated with the classes Clostridia, Bacilli, Gammaproteobacteria, Epsilonproteobacteria, Bacteroidia, and Fusobacteria. Produced water collected at the last time point (day 187) consisted almost entirely of sequences similar to Clostridia and showed a decrease in bacterial abundance by 3 orders of magnitude compared to the prefracturing fluids and produced water samplesfrom earlier time points. Geochemical analysis showed that produced water contained higher concentrations of salts and total radioactivity compared to prefracturing fluids. This study provides evidence of long-term subsurface selection of the microbial community introduced through hydraulic fracturing, which may include significant implications for disinfection as well as reuse of produced water in future fracturing operations.

TI "Replica-Extraction-Transfer" Nanostructure-Initiator Mass Spectrometry Imaging of Acoustically Printed Bacteria SO ANALYTICAL CHEMISTRY LA English DT Article ID METABOLOMICS; IONIZATION AB Traditionally, microbes are studied under controlled laboratory conditions as isolates in planktonic culture. However, this is a vast extrapolation from their natural state; development of new techniques is required to decipher the largely unknown world of microbial chemical interactions in more realistic environments. The field of mass spectrometry imaging has made significant progress in localizing metabolites in and around bacterial colonies, primarily by using MALDI and ESI-based techniques that interrogate the top surface of the sample. Unfortunately, surface-based laser-desorption techniques, such as nanostructure-initiator mass spectrometry (NIMS), which has advantages in detection of small metabolite compounds and low background, has not been suitable for direct microbe imaging because desorption/ionization occurs on the bottom of the sample. Here, we describe a "replica-extraction-transfer" (REX) technique that overcomes this barrier by transferring biomolecules from agar cultures of spatially arrayed bacterial colonies onto NIMS surfaces; further, we demonstrate that acoustic printing of bacteria can be used to create complex colony geometries to probe microbial interactions with NIMS imaging. REX uses a solvent-laden semisolid (e.g., gel) to first extract metabolites from a microbial sample, such as a biofilm or agar culture; the metabolites are then replica "stamped" onto the NIMS surface. Using analytical standards we show that REX NIMS effectively transfers and detects a range of small molecule compounds including amino acids and polyamines. This approach is then used to analyze the metabolite composition of streaked Shewanella oneidensis MR1 and Pseudomonas stutzeri RCH2 colonies and further resolve complex patterns produced by acoustic printing of liquid microbial cultures. Applying multivariate statistical analysis of the NIMS imaging data identified ions that were localized to different regions between and within colonies, as well as to the agar gel. Subsequent high-resolution tandem mass spectrometry was used to characterize two species-specific lipids that correlated with the spatial location of each microbial species and were found to be highly abundant in cell extracts. Overall, the use of acoustic printing of bacteria with REX NIMS imaging will extend the range of analytical capabilities available for characterization of microbial interactions with mass spectrometry.

TI Direct Real-Time Detection of Vapors from Explosive Compounds SO ANALYTICAL CHEMISTRY LA English DT Article ID ION MOBILITY SPECTROMETRY; MASS-SPECTROMETRY; NO3 AB The real-time detection of vapors from low volatility explosives including PETN, tetryl, RDX, and nitroglycerine along with various compositions containing these substances was demonstrated. This was accomplished with an atmospheric flow tube (AFT) using a nonradioactive ionization source coupled to a mass spectrometer. Direct vapor detection was accomplished in less than 5 s at ambient temperature without sample preconcentration. The several seconds of residence time of analytes in the AFT provided a significant opportunity for reactant ions to interact with analyte vapors to achieve ionization. This extended reaction time, combined with the selective ionization using the nitrate reactant ions (NO3- and NO3-center dot HNO3), enabled highly sensitive explosives detection from explosive vapors present in ambient laboratory air. Observed signals from diluted explosive vapors indicated detection limits below 10 ppq(v) using selected ion monitoring (SIM) of the explosive-nitrate adduct at m/z 349, 378, 284, and 289 for tetryl, PETN, RDX, and NG, respectively. Also provided is a demonstration of the vapor detection from 10 different energetic formulations sampled in ambient laboratory air, including double base propellants, plastic explosives, and commercial blasting explosives using SIM for the NG, PETN, and RDX product ions.

TI Higher-order spin noise statistics SO NEW JOURNAL OF PHYSICS LA English DT Article ID MAGNETIC-RESONANCE; NETWORKS; DYNAMICS AB The optical spin noise spectroscopy (SNS) is a minimally invasive route toward obtaining dynamical information about electrons and atomic gases by measuring mesoscopic time-dependent spin fluctuations. Recent improvements of the sensitivity of SNS should make it possible to observe higher-order spin correlators at thermodynamic equilibrium. We develop theoretical methods to explore higher-order (third and fourth) cumulants of the spin noise in the frequency domain. We make predictions for the possible functional form of these correlators in single quantum dot experiments and then apply the method of the stochastic path integral to estimate the effects of many-body interactions.

CA Belle Collaboration TI Measurement of the CP violation parameters in B-0 -> pi(+) pi(-) decays SO PHYSICAL REVIEW D LA English DT Article ID BELLE; DETECTOR AB We present a measurement of the charge-parity (CP) violating parameters in B-0 -> pi(+) pi(-) decays. The results are obtained from the final data sample containing 772 x 10(6) B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+) e(-) collider. We obtain the CP violation parameters A(cp)(B-0 -> pi(+) pi(-)) = +0.33 +/- 0.06(stat) +/- 0.03(syst), S-cp(B-0 -> pi(+) pi(-)) = -0.64 +/- 0.08(stat) +/- 0.03(syst), where A(CP) and S-CP represent the direct and mixing-induced CP asymmetries in B-0 -> pi(+) pi(-) decays, respectively. Using an isospin analysis including results from other Belle measurements, we find 23.8 degrees < phi(2) < 66.8 degrees is disfavored at the 1 sigma level, where phi(2) is one of the three interior angles of the Cabibbo-Kobayashi-Maskawa unitarity triangle related to B-u,B-d decays.

TI In-Beam gamma-Ray Spectroscopy of Mg-34,Mg-36,Mg-38: Merging the N=20 and N=28 Shell Quenching SO PHYSICAL REVIEW LETTERS LA English DT Article ID ISOTOPES; DEFORMATION; TRANSITION; STABILITY AB Neutron-rich N = 22, 24, 26 magnesium isotopes were studied via in-beam gamma-ray spectroscopy at the RIKEN Radioactive Isotope Beam Factory following secondary fragmentation reactions on a carbon target at approximate to 200 MeV/nucleon. In the one-and two-proton removal channels from Al-39 and Si-40 beams, two distinct gamma-ray transitions were observed in Mg-38, while in the one-proton removal reaction from Al-37 a new transition was observed in addition to the known 2(1)(+) -> 0(g.s.)(+) decay. From the experimental systematics and comparison to theoretical predictions it is concluded that the transitions belong to the 2(1)(+) -> 0(g.s.)(+) and 4(1)(+) -> 2(1)(+) decays in Mg-36 and Mg-38, respectively. For Mg-34, previously reported 2(1)(+) and 4(1)(+) level energies were remeasured. The deduced E(4(1)(+))/E(2(1)(+)) ratios for 34; 36; 38Mg of 3.14(5), 3.07(5), and 3.07(5) are almost identical and suggest the emergence of a large area of deformation extending from the N = 20 to the N = 28 shell quenching.

TI Molecular Dynamics Simulations of Classical Stopping Power SO PHYSICAL REVIEW LETTERS LA English DT Article ID NATIONAL IGNITION FACILITY; HEAVY-IONS; MASS-DEPENDENCE; SELF-DIFFUSION; DENSE-PLASMAS; ENERGY-LOSS; PHYSICS; FUSION; COEFFICIENTS; SCATTERING AB Molecular dynamics can provide very accurate tests of classical kinetic theory; for example, unambiguous comparisons can be made for classical particles interacting via a repulsive 1/r potential. The plasma stopping power problem, of great interest in its own right, provides an especially stringent test of a velocity-dependent transport property. We have performed large-scale (similar to 10(4)-10(6) particles) molecular dynamics simulations of charged-particle stopping in a classical electron gas that span the weak to moderately strong intratarget coupling regimes. Projectile-target coupling is varied with projectile charge and velocity. Comparisons are made with disparate kinetic theories (both Boltzmann and Lenard-Balescu classes) and fully convergent theories to establish regimes of validity. We extend these various stopping models to improve agreement with the MD data and provide a useful fit to our results.

TI Existence of Orbital Order and its Fluctuation in Superconducting Ba(Fe1-xCox)(2)As-2 Single Crystals Revealed by X-ray Absorption Spectroscopy SO PHYSICAL REVIEW LETTERS LA English DT Article ID IRON; TRANSITION; ANISOTROPY; BAFE2AS2; STATE AB We performed temperature dependent x-ray linear dichroism (XLD) experiments on an iron pnictide system, Ba(Fe1-xCox)(2)As-2 with x = 0.00, 0.05, 0.08, and 0.10 to experimentally verify the existence of orbital ordering (OO). Substantial XLD was observed in polarization dependent x-ray absorption spectra of Fe L edges. By exploiting the difference in the temperature dependent behaviors, OO, and structure contributions to XLD could be clearly separated. The observed OO signal indicates different occupation numbers for d(yz) and d(zx) orbitals and supports the existence of ferro-OO. The results are also consistent with the theoretical prediction. Moreover, we find substantial OO signal well above the structural and magnetic transition temperatures, which suggests the existence of strong OO fluctuations up to high temperatures. C1 [Kim, Y.

An implosion with extended drive and at reduced peak power of 350 TW achieved the highest compression with fuel areal density of similar to 1.3 +/- 0.1 g/cm(2), representing a significant step from previously measured similar to 1.0 g/cm(2) toward a goal of 1.5 g/cm(2).

Methods: Hazard ratios from Cox proportional survival analyses of all-cause and cause-specific mortality vs. usual walking pace (min/mile) in 7,374 male and 31,607 female recreational walkers. Survival times were left censored for age at entry into the study. Other causes of death were treated as a competing risk for the analyses of cause-specific mortality. All analyses were adjusted for sex, education, baseline smoking, prior heart attack, aspirin use, diet, BMI, and walking energy expenditure. Deaths within one year of baseline were excluded. Results: The National Death Index identified 1968 deaths during the average 9.4-year mortality surveillance. Each additional minute per mile in walking pace was associated with an increased risk of mortality due to all causes (1.8% increase, P=10(-5)), cardiovascular diseases (2.4% increase, P=0.001, 637 deaths), ischemic heart disease (2.8% increase, P=0.003, 336 deaths), heart failure (6.5% increase, P=0.001, 36 deaths), hypertensive heart disease (6.2% increase, P=0.01, 31 deaths), diabetes (6.3% increase, P=0.004, 32 deaths), and dementia (6.6% increase, P=0.0004, 44 deaths). Those reporting a pace slower than a 24-minute mile were at increased risk for mortality due to all-causes (44.3% increased risk, P=0.0001), cardiovascular diseases (43.9% increased risk, P=0.03), and dementia (5.0-fold increased risk, P=0.0002) even though they satisfied the current exercise recommendations by walking >= 7.5 metabolic equivalent (MET)-hours per week. Conclusions: The risk for mortality: 1) decreases in association with walking intensity, and 2) increases substantially in association for walking pace >= 24 minute mile (equivalent to <400m during a six-minute walk test) even among subjects who exercise regularly.

TI Molecular Crowding Favors Reactivity of a Human Ribozyme Under Physiological Ionic Conditions SO BIOCHEMISTRY LA English DT Article ID X-RAY-SCATTERING; SMALL-ANGLE SCATTERING; DELTA VIRUS RIBOZYME; INTRACELLULAR MAGNESIUM; STRUCTURAL-ANALYSES; RNA; SAXS; RIBOSWITCH; STABILITY; SECONDARY AB In an effort to relate RNA folding to function under cellular-like conditions, we monitored the self-cleavage reaction of the human hepatitis delta virus-like CPEB3 ribozyme in the background of physiological ionic concentrations and various crowding and cosolute agents. We found that at physiological free Mg2+ concentrations (similar to 0.1-0.5 mM), both crowders and cosolutes stimulate the rate of self-cleavage, up to similar to 6-fold, but that in 10 mM Mg2+ (conditions widely used for in vitro ribozyme studies) these same additives have virtually no effect on the self-cleavage rate. We further observe a dependence of the self-cleavage rate on crowder size, wherein the level of rate stimulation is diminished for crowders larger than the size of the unfolded RNA. Monitoring effects of crowding and cosolute agents on rates in biological amounts of urea revealed additive-promoted increases at both low and high Mg2+ concentrations, with a maximal stimulation of more than 10-fold and a rescue of the rate to its urea-free values. Small-angle X-ray scattering experiments reveal a structural basis for this stimulation in that higher-molecular weight crowding agents favor a more compact form of the ribozyme in 0.5 mM Mg2+ that is essentially equivalent to the form under standard ribozyme conditions of 10 mM Mg2+ without a crowder. This finding suggests that at least a portion of the rate enhancement arises from favoring the native RNA tertiary structure. We conclude that cellular-like crowding supports ribozyme reactivity by favoring a compact form of the ribozyme, but only under physiological ionic and cosolute conditions.

TI Hole doping effect on superconductivity in Ce(Co1-xRux)In-5 SO PHYSICAL REVIEW B LA English DT Article ID KONDO-LATTICE; CECOIN5 AB CeCoIn5, which has a superconducting transition temperature of 2.3 K, provides an excellent opportunity to study the interplay of superconductivity and magnetism near an antiferromagnetic quantum critical point. Previous studies have explored the effects of electron doping, magnetic field, and positive pressure on this system. To determine the effect of hole doping, we have grown single crystals of Ce(Co1-xRux)In-5 in indium flux. The crystal structure of these Ru-doped samples was identified by powder XRD as the HoCoGa5-type. We find that the coherence temperature T* and the superconducting transition temperature T-c decrease monotonically with increasing Ru content. Unlike the case of hole doping in CeCo(In5-xCdx) alloys in which antiferromagnetism starts to emerge at x = 0.025, we find no magnetic transition at our maximal nominal doping of x(nom) = 0.5, where T-c is suppressed to 1.5 K. We discuss possible reasons for this difference between these two cases of hole doping. C1 [Ou, M. N.; Gofryk, K.; Baumbach, R. E.; Thompson, J. D.; Lawrence, J. M.; Bauer, E.

One issue studied is the overcooled high-T phase, in which we calculate quasinormal sound modes. We do not find instabilities associated with other first-order phase transitions, but nevertheless observe drastic changes in sound propagation and dissipation. The rest of the paper considers a cluster of the high-T phase in the UV in coexistence with the low-T phase, in a simplified ansatz in which the wall separating them is positioned only in the holographic coordinate. This allows one to find the force on the wall and classical motion of the cluster. When classical motion is forbidden, we evaluate the tunneling probability through the remaining barrier.

The characterization of fluid flow parameters in such in-vitro perfused tissue models is a critical step towards better understanding and manipulating the tumor microenvironment. However, traditional optical flow measurement methods are inapplicable because of the opacity of blood and the thickness of the tissue sample. In order to overcome the limitations of optical method we demonstrate the feasibility of using phase-contrast x-ray imaging to perform microscale particle image velocimetry (PIV) measurements of flow in blood perfused hydrated tissue-representative microvessels. However, phase contrast x-ray images significantly depart from the traditional PIV image paradigm, as they have high intensity background, very low signal-to-noise ratio, and volume integration effects. Hence, in order to achieve accurate measurements special attention must be paid to the image processing and PIV cross-correlation methodologies. Therefore we develop and demonstrate a methodology that incorporates image preprocessing as well as advanced PIV cross-correlation methods to result in measured velocities within experimental uncertainty.

TI Structure of nanoscale gas bubbles in metals SO APPLIED PHYSICS LETTERS LA English DT Article ID HELIUM BUBBLES; MOLECULAR-DYNAMICS; FE-HE; GROWTH; ALLOYS; IRON; IRRADIATION; NUCLEATION; PARAMETERS; EVOLUTION AB A usual way to estimate the amount of gas in a bubble inside a metal is to assume thermodynamic equilibrium, i.e., the gas pressure P equals the capillarity force 2 gamma/R, with gamma the surface energy of the host material and R the bubble radius; under this condition there is no driving force for vacancies to be emitted or absorbed by the bubble. In contrast to the common assumption that pressure inside a gas or fluid bubble is constant, we show that at the nanoscale this picture is no longer valid. P and density can no longer be defined as global quantities determined by an equation of state (EOS), but they become functions of position because the bubble develops a core-shell structure. We focus on He in Fe and solve the problem using both continuum mechanics and empirical potentials to find a quantitative measure of this effect. We point to the need of redefining an EOS for nanoscale gas bubbles in metals, which can be obtained via an average pressure inside the bubble. The resulting EOS, which is now size dependent, gives pressures that differ by a factor of two or more from the original EOS for bubble diameters of 1 nm and below. (C) 2013 AIP Publishing LLC.

TI Ultrafast and steady-state laser heating effects on electron relaxation and phonon coupling mechanisms in thin gold films SO APPLIED PHYSICS LETTERS LA English DT Article ID PICOSECOND LIGHT-PULSES; SCATTERING; THERMALIZATION; METALS; THERMOREFLECTANCE; GENERATION; LATTICE AB We study the scattering mechanisms driving electron-phonon relaxation in thin gold films via pump-probe time-domain thermoreflectance. Electron-electron scattering can enhance the effective rate of electron-phonon relaxation when the electrons are out of equilibrium with the phonons. In order to correctly and consistently infer electron-phonon coupling factors in films on different substrates, we must account for the increase in steady-state lattice temperature due to laser heating. Our data provide evidence that a thermalized electron population will not directly exchange energy with the substrate during electron-phonon relaxation, whereas this pathway can exist between a non-equilibrium distribution of electrons and a non-metallic substrate.

TI Plasticity mechanism for copper extrusion in through-silicon vias for three-dimensional interconnects SO APPLIED PHYSICS LETTERS LA English DT Article ID X-RAY MICRODIFFRACTION; THERMAL-STRESSES; THIN-FILMS; INTEGRATION; CU AB In this paper, we demonstrated the plasticity mechanism for copper (Cu) extrusion in through-silicon via structures under thermal cycling. The local plasticity was directly observed by synchrotron x-ray micro-diffraction near the top of the via with the amount increasing with the peak temperature. The Cu extrusion was confirmed by Atomic Force Microscopy (AFM) measurements and found to be consistent with the observed Cu plasticity behavior. A simple analytical model elucidated the role of plasticity during thermal cycling, and finite element analyses were carried out to confirm the plasticity mechanism as well as the effect of the via/Si interface. The model predictions were able to account for the via extrusions observed in two types of experiments, with one representing a nearly free sliding interface and the other a strongly bonded interface. Interestingly, the AFM extrusion profiles seemed to contour with the local grain structures near the top of the via, suggesting that the grain structure not only affects the yield strength of the Cu and thus its plasticity but could also be important in controlling the pop-up behavior and the statistics for a large ensemble of vias.

Single surface resonant multipactor has been previously identified as one of the major limitations on the practical application of DLA structures in electron accelerators. In this paper, we report the results of an experiment that demonstrated suppression of multipactor growth in an X-band DLA structure through the use of an applied axial magnetic field.

TI The effect of oxygen vacancies on the electronic phase transition in La1/3Sr2/3FeO3 films SO APPLIED PHYSICS LETTERS LA English DT Article ID CHARGE DISPROPORTIONATION; SINGLE-CRYSTALS; TEMPERATURE; GROWTH; PR; LA; ND AB Synchrotron x-ray diffraction and electrical resistivity were used to probe the electronic phase transition in two strained La1/3Sr2/3FeO3 films on (001) SrTiO3 substrates, one nominally stoichiometric and one with a higher concentration of oxygen vacancies. We present evidence that oxygen vacancies inhibit the size of charge ordered domains and reduce the abruptness of the phase transition. Additionally, the correlation lengths measured from (4/3 4/3 4/3) peaks, arising from charge disproportionation, increase rapidly across the transition, suggesting that the resistivity increase at the transition temperature is caused by the nucleation and growth of charge ordered domains.

In this work, we demonstrate a blue shift in the band gap of GaAs micropillars of greater than 50 meV using SiNx. GaAs micropillars were fabricated and conformally coated with highly strained SiNx. The band gap and strain state of the micropillars were measured using room temperature photoluminescence and Raman spectroscopy. The GaAs was shown to be in uniaxial compression, leading to a linear increase in the band gap. Removal of the strained layer resulted in relaxation back to the unstrained state.

A new technique is demonstrated that allows analysis of MRO using X-rays. Diffraction data were collected from a sample consisting of densely packed polystyrene-latex micro-spheres. Ptychography is used to reconstruct the sample transmission function and fluctuation microscopy applied to characterize structural order producing a detailed 'fluctuation map' allowing analysis of the sample at two distinct length scales. Independent verification is provided via X-ray diffractometry. Simulations of dense random packing of spheres have also been used to explore the origin of the structural order measured.

Recovering the real space contrast of a scattering object from these patterns currently requires a reconstruction process with user guidance in a number of steps, introducing severe bottlenecks in data processing. We present a series of measures that replace user guidance with algorithms that reconstruct contrasts in an unsupervised fashion. We demonstrate the feasibility of automating the reconstruction process by generating hundreds of contrasts obtained from soot particle diffraction experiments.

TI Measuring the t(t)over-barh coupling from same-sign dilepton+2b measurements SO PHYSICAL REVIEW D LA English DT Article ID BOSON; LHC AB We evaluate the potential of a dedicated search for t (t) over barh production in the SSDL + 2b channel. Such a measurement provides direct access to the top Yukawa coupling, since the sensitivity is not convolved with the loop-level h gamma gamma as is the case for present t (t) over barh searches. Furthermore, susceptibility to uncertainties in the Higgs width can be reduced by considering a ratio of SSDL + 2b rates with those of the performed Wh -> WWW* measurement. The SSDL channel can therefore rely primarily on the already well-measured h -> WW* decay. This feasibility study required the development of a new calculation method for "fake" leptons, which constitute the dominant background to our search. Combining measurements from LHC7, LHC8, and in the future LHC14 for the Higgs coupling fit would help resolve any remaining ambiguity between the top Yukawa coupling and a beyond standard model contribution to the hgg coupling.

CA Hadron Spectrum Collaboration TI Toward the excited isoscalar meson spectrum from lattice QCD SO PHYSICAL REVIEW D LA English DT Article ID SCATTERING MATRIX; HYBRID MESONS; FINITE-VOLUME; MODEL; STATES; GLUONS AB We report on the extraction of an excited spectrum of isoscalar mesons using lattice QCD. Calculations on several lattice volumes are performed with a range of light quark masses corresponding to pion masses down to similar to 400 MeV. The distillation method enables us to evaluate the required disconnected contributions with high statistical precision for a large number of meson interpolating fields. We find relatively little mixing between 1/root 2(u (u) over bar + d (d) over bar) and s (s) over bar in most J(PC) channels; one notable exception is the pseudoscalar sector where the approximate SU(3)(F) octet, singlet structure of the eta, eta' is reproduced. We extract exotic J(PC) states, identified as hybrid mesons in which an excited gluonic field is coupled to a color-octet q (q) over bar pair, along with nonexotic hybrid mesons embedded in a q (q) over bar -like spectrum.

Often, however, the protonation states are difficult to establish experimentally. This is of particular importance in the oxygen evolving complex of photosystem II, where identification of the bridging oxo protonation states is one of the essential requirements toward unraveling the mechanism. In order to establish a combined experimental and theoretical protocol for the determination of protonation states, we have systematically investigated a series of Mn model complexes by Mn K pre-edge X-ray absorption spectroscopy. An ideal test case for selective bis-mu-oxo-bridge protonation in a Mn dimer is represented by the system [Mn-2(IV)(salpn)(2)(mu-OHn)(2)](n+). Although the three species [Mn-2(IV)(salPn)(2)(mu-O)(2)], [Mn-2(IV)(salpn)(2)(mu-O)(mu-OH)](+) and [Mn-2(IV)(salpn)(2)(mu-OH)(2)](2+) differ only in the protonation of the oxo bridges, they exhibit distinct differences in the pre-edge region while maintaining the same edge energy. The experimental spectra are correlated in detail to theoretically calculated spectra. A time-dependent density functional theory approach for calculating the pre-edge spectra of molecules with multiple metal centers is presented, using both high spin (HS) and broken symmetry (BS) electronic structure solutions. The most intense pre-edge transitions correspond to an excitation of the Mn Is core electrons into the unoccupied orbitals of local e(g) character (d(z)(2) and d(xy) based in the chosen coordinate system). The lowest energy experimental feature is dominated by excitations of 1s-alpha electrons, and the second observed feature is primarily attributed to 1s-beta electron excitations. The observed energetic separation is due to spin polarization effects in spin-unrestricted density functional theory and models final state multiplet effects. The effects of spin polarization on the calculated Mn K pre-edge spectra, in both the HS and BS solutions, are discussed in terms of the strength of the antiferromagnetic coupling and associated changes in the covalency of Mn-O bonds. The information presented in this paper is complemented with the X-ray emission spectra of the same compounds published in an accompanying paper. Taken together, the two studies provide the foundation for a better understanding of the X-ray spectroscopic data of the oxygen evolving complex (OEC) in photosystem II.

A set of dinuclear bis-mu-oxo-bridged Mn-IV complexes in different protonation states was studied by K beta emission spectroscopy to form the foundation for unraveling the protonation states in the native complex. The valence-to-core regions (valence-to-core XES) of the spectra show significant changes in intensity and peak position upon protonation. DFT calculations were performed to simulate the valence-to-core XES spectra and to assign the spectral features to specific transitions. The K beta(2,5) peaks arise primarily from the ligand 2p to Mn Is transitions, with a characteristic low energy shoulder appearing upon oxo-bridge protonation. The satellite K beta '' peak provides a more direct signature of the protonation state change, since the transitions originating from the 2s orbitals of protonated and unprotonated mu-oxo bridges dominate this spectral region. The energies of the K beta '' features differ by similar to 3 eV and thus are well resolved in the experimental spectra. Additionally, our work explores the chemical resolution limits of the method, namely, whether a mixed (mu-O)(mu-OH2) motif can be distinguished from a symmetric (mu-OH)(2) one. The results reported here highlight the sensitivity of K beta valence-to-core XES to single protonation state changes of bridging ligands, and form the basis for further studies of oxo-bridged polymetallic complexes and metalloenzyme active sites. In a complementary paper, the results from X-ray absorption spectroscopy of the same Mn-IV dimer series are discussed.

The highly nonstoichiometric TTB Ba0.5-xTaO3-x (x = 0.25-0.325) compositions are stabilized via the interpolation of Ba2+ cations and (TaO)(3+) groups into pentagonal tunnels, forming distinct Ba chains and alternate Ta-O rows in the pentagonal tunnels along the c axis. The slightly nonstoichiometric Ba0.5-xTaO3-x (x = 0-0.1) compositions incorporate framework oxygen and tunnel cation deficiencies in the TTB structure. These two mechanisms result in phase separation within the 0.1 < x < 0.25 nonstoichiometric range, resulting in two closely related (TaO)(3+)-containing and (TaO)(3+)-free TTB phases. The highly nonstoichiometric (TaO)(3+)-containing phase exhibits Ba2+ cationic migration. The incorporation of (TaO)(3+) units into the pentagonal tunnel and the local relaxation of the octahedral framework around the (TaO)(3+) units are revealed by diffraction data analysis and are shown to affect the transport and polarization properties of these compositions.

To resolve this enigma, we investigate the disorder effects of nonmagnetic Zn impurities in the strong (unitary) scattering limit on various properties of the system in the s(+/-)-wave superconducting pairing state. The lattice Bogoliubov-de Gennes equation (BdG) is solved self-consistently based on a minimal two-orbital model with an extended range of impurity concentrations. We find that Zn impurity is best modeled as a defect, where charge is mainly localized, but scattering is extended over a few lattice sites. With increasing Zn concentration, the density of states shows a gradual filling of the gap, revealing the impurity-induced pair-breaking effect. Moreover, both the disorder configuration-averaged superconducting order parameter and the superfluid density are dramatically suppressed toward the dirty limit, indicating the violation of the Anderson theorem for conventional s-wave superconductors and the breakdown of the Abrikosov-Gorkov theory for impurity-averaged Green's functions. Furthermore, we find that the superconducting phase is fully suppressed close to the critical impurity concentration of roughly n(imp) approximate to 10%, in agreement with recent experiments.

In this spin qubit, quantum information is encoded in a low-lying singlet-triplet space much as in the case of a two-electron DQD qubit. We find that initialization, manipulation, and readout can be performed similarly to the two-electron case, and that energy gaps remain large enough that these operations can be performed robustly.

Ahigh-quality powder sample characterized by x-ray diffraction that indicates a relatively low Co-Al inversion parameter x = 0.057(20) in (Co1-x Al x)[ Al2-x Co x] O-4, shows a broad maximum around 15 K in.(T) and a sharp peak at TN in heat capacity Cp. The average-ordered magnetic moment of Co2+ (S = 3/2) ions at the A site is estimated to be 2.4(1) mu B from NMR and 1.9(5) mu B from ND which are smaller than the expected value of 3 B for S = 3/2 and g = 2. Antiferromagnetic spin fluctuations and correlations in the paramagnetic state are revealed from the., NMR, and ND measurements, which are due to spin frustration and site inversion effects in the system. The ND data also show short-range dynamic magnetic ordering that persists to a temperature that is almost twice T-N. C1 [Roy, B.; Pandey, Abhishek; Zhang, Q.; Vaknin, D.; Johnston, D.

TI Single-particle and collective excitations in Ni-63 SO PHYSICAL REVIEW C LA English DT Article ID ROTATIONAL BANDS; SUPERDEFORMED BAND; NUCLEUS; DECAY; ISOTOPES; NI-56; CA-48; SPIN; N=40; N=32 AB A study of excited states in Ni-63 up to an excitation energy of 28 MeV and a probable spin of 57/2 was carried out with the Mg-26(Ca-48,2 alpha 3n gamma)Ni-63 reaction at beam energies between 275 and 320 MeV. Three collective bands, built upon states of single-particle character, were identified. For two of the three bands, the transition quadrupole moments were extracted, herewith quantifying the deformation at high spin. The results have been compared with shell-model and cranked Nilsson-Strutinsky calculations. Despite the Z = 28 shell closure and the approach to the purported N = 40 subshell, the Ni-63 isotope is able to sustain collective excitations at moderate and high spin.

TI R-matrix analysis and prediction of low-energy neutron-induced fission cross sections for a range of Pu isotopes SO PHYSICAL REVIEW C LA English DT Article ID NUCLEAR-SCIENCE; AVERAGE NEUTRON; MODEL; ACTINIDES; LIBRARY; BARRIER; CAPTURE; REGION AB Neutron-induced fission cross sections for the plutonium isotopes from 236 to 244 are computed for neutrons of a few keV up to 5.5 MeV incident energy, using the Hauser-Feshbach statistical theory of nuclear reactions, modified to treat the fission decay channel in the R-matrix formalism. The fluctuations of the fission decay widths owing to the presence of intermediate structures in the second well and to the coupling of class I and class II states are simulated by Monte Carlo sampling of the underlying model parameter distributions. The accuracy of this approach is tested relative to the results of well-known analytical formulations for the average fission cross sections. Special attention is paid to the choice and consistency of the model input parameters, in part obtained from microscopic nuclear structure calculations. The predictive capabilities offered by our method are tested against the neutron-induced fission of the very short-lived Pu-243 (tau(1/2) = 4.95 h) for which no measurement exist. Our calculations, consistent over all the Pu isotope series, demonstrate that Pu-243 is fissile, in contrast to what is reported in the standard ENDF/B-VII.1 and JEFF-3.1.2 evaluated libraries. No recommendations are made in the JENDL-4.0 data library for this isotope. C1 [Bouland, O.] CEA, DEN, DER, SPRC,Phys Studies Lab, F-13108 St Paul Les Durance, France. [Lynn, J.

TI Neutrino-nuclear response and photonuclear reactions SO PHYSICAL REVIEW C LA English DT Article ID DOUBLE-BETA DECAYS; 141PR AB Photonuclear reactions are shown to be used for studying neutrino (weak) nuclear responses involved in astroneutrino nuclear interactions and double beta decays. Charged current weak responses for ground and excited states are studied by using photonuclear reactions through isobaric analog states of those states, while neutral current weak responses for excited states are studied by using photonuclear reactions through the excited states. The weak interaction strengths are studied by measuring the cross sections of the photonuclear reactions, and the spin and parity of the states are studied by measuring angular correlations of particles emitted from the photonuclear reactions. Medium-energy polarized photons obtained from laser photons scattered off GeV electrons are very useful. Nuclear responses studied by photonuclear reactions are used to evaluate neutrino (weak) nuclear responses, i.e., nuclear beta and double beta matrix elements and neutrino-nuclear interactions, and to verify theoretical calculations for them.

Nevertheless, challenging issues such as poor reaction kinetics and the short-term stability of the MOR are the main drawbacks of such catalysts and limit their applications. Herein, we have developed a facile approach to encapsulate Pt nanoparticles (NPs) inside the nanochannels of porous carbon nanotubes (CNTs; Pt-in-CNTs) as a new enhanced electrocatalytic material. The as-prepared CNTs offer simultaneously ordered diffusion channels for ions and a confinement effect for the NPs, which both facilitate the promotion of catalytic kinetics and avoid the Ostwald ripening of Pt NPs, thus leading to high activity and durable cycle life as an anode catalyst for MOR. This work provides a new approach for enhancing the stability and activity by optimizing the structure of the catalyst, and the Pt-in-CNTs represent the most durable catalysts ever reported for MOR.

Root-mean-square differences from Aerosol Robotic Network ground-based observations were 0.01 at wavelengths between 500-1020 nm, 0.02 at 380 and 1640 nm, and 0.03 at 440 nm in four clear-sky fly-over events, and similar in ground side-by-side comparisons. Changes in the above-aircraft AOD across 3 km deep spirals were typically consistent with integrals of coincident in situ (on Department of Energy Gulfstream 1 with 4STAR) and lidar (on NASA B200) extinction measurements within 0.01, 0.03, 0.01, 0.02, 0.02, and 0.02 at 355, 450, 532, 550, 700, and 1064 nm, respectively, despite atmospheric variations and combined measurement uncertainties. Finer vertical differentials of the 4STAR measurements matched the in situ ambient extinction profile within 14% for one homogeneous column. For the AOD observed between 350 and 1660 nm, excluding strong water vapor and oxygen absorption bands, estimated uncertainties were similar to 0.01 and dominated by (then) unpredictable throughput changes, up to +/-0.8%, of the fiber optic rotary joint. The favorable intercomparisons herald 4STAR's spatially resolved high-frequency hyperspectral products as a reliable tool for climate studies and satellite validation.

TI Enhancing the chemical mixture methodology in emergency preparedness and consequence assessment analysis SO TOXICOLOGY LA English DT Article DE Chemical mixture methodology; Health code numbers; Weighting factors; Acute health effects; Exposure route; Protective action criteria; Priority ranking ID RESPONSE PLANNING GUIDELINES; HAZARDOUS SUBSTANCES AB Emergency preparedness personnel at U.S. Department of Energy (DOE) facilities use the chemical mixture methodology (CMM) to estimate the potential health impacts to workers and the public from the unintended airborne release of chemical mixtures. The CMM uses a Hazard Index (HI) for each chemical in a mixture to compare a chemical's concentration at a receptor location to an appropriate concentration limit for that chemical. This limit is typically based on Protection Action Criteria (PAC) values developed and published by the DOE. As a first cut, the CMM sums the HIs for all the chemicals in a mixture to conservatively estimate their combined health impact. A cumulative HI > 1.0 represents a concentration exceeding the concentration limit and indicates the potential for adverse health effects. Next, Health Code Numbers (HCNs) are used to identify the target organ systems that may be impacted by exposure to each chemical in a mixture. The sum of the HIs for the maximally impacted target organ system is used to provide a refined, though still conservative, estimate of the potential for adverse health effects from exposure to the chemical mixture. This paper explores approaches to enhance the effectiveness of the CMM by using HCN weighting factors. A series of 24 case studies have been defined to evaluate both the existing CMM and three new approaches for improving the CMM. The first approach uses a set of HCN weighting factors that are applied based on the priority ranking of the HCNs for each chemical. The second approach uses weighting factors based on the priority rankings of the HCNs established for a given type of concentration limit. The third approach uses weighting factors that are based on the exposure route used to derive PAC values and a priority ranking of the HCNs (the same ranking as used in the second approach). Initial testing indicates that applying weighting factors increases the effectiveness of the CMM in general, though care must be taken to avoid introducing non-conservative results. In the near future, additional testing and analysis will be conducted that may lead to the adoption of one of the tested approaches into the CMM. (C) 2012 Elsevier Ireland Ltd. All rights reserved.

TI Molecular target sequence similarity as a basis for species extrapolation to assess the ecological risk of chemicals with known modes of action SO AQUATIC TOXICOLOGY LA English DT Article DE Predictive toxicology; Protein sequence similarity; Molecular target; Relative intrinsic susceptibility; Conserved functional domains ID ZEBRAFISH DANIO-RERIO; LIFE-CYCLE TEST; ENVIRONMENTAL ESTROGENS; INSECTICIDE RESISTANCE; ENDOCRINE DISRUPTERS; PIMEPHALES-PROMELAS; GOBIOCYPRIS-RARUS; JAPANESE MEDAKA; SODIUM-CHANNELS; FATHEAD MINNOW AB It is not feasible to conduct toxicity tests with all species that may be impacted by chemical exposures. Therefore, cross-species extrapolation is fundamental to environmental risk assessment. Recognition of the impracticality of generating empirical, whole organism, toxicity data for the extensive universe of chemicals in commerce has been an impetus driving the field of predictive toxicology. We describe a strategy that leverages expanding databases of molecular sequence information together with identification of specific molecular chemical targets whose perturbation can lead to adverse outcomes to support predictive species extrapolation. This approach can be used to predict which species may be more (or less) susceptible to effects following exposure to chemicals with known modes of action (e.g., pharmaceuticals, pesticides). Primary amino acid sequence alignments are combined with more detailed analyses of conserved functional domains to derive the predictions. This methodology employs bioinformatic approaches to automate, collate, and calculate quantitative metrics associated with cross-species sequence similarity of key molecular initiating events (MIEs). Case examples focused on the actions of (a) 17 alpha-ethinyl estradiol on the human (Homo sapiens) estrogen receptor; (b) permethrin on the mosquito (Aedes aegypti)voltage-gated para-like sodium channel; and (c) 17 beta-trenbolone on the bovine (Bos taurus) androgen receptor are presented to demonstrate the potential predictive utility of this species extrapolation strategy. The examples compare empirical toxicity data to cross-species predictions of intrinsic susceptibility based on analyses of sequence similarity relevant to the MIEs of defined adverse outcome pathways. Through further refinement, and definition of appropriate domains of applicability, we envision practical and routine utility for the molecular target similarity-based predictive method in chemical risk assessment, particularly where testing resources are limited.

Elements of the theory are now routinely being used in many parts of the world in the design of novel alloys and in the interpretation of a variety of experimental data. However, current experimental and theoretical understanding is limiting technological progress. The purpose of this atom probe tomography study was to track atom distributions during the bainite reaction in a nanocrystalline steel. The results are providing new experimental evidence on subjects critically relevant to the understanding of the atomic mechanisms controlling bainitic ferrite formation, such as the incomplete transformation phenomenon, the carbon supersaturation of ferrite, and the plastic accommodation of the surrounding austenite.

TI Utilizing novel diversity estimators to quantify multiple dimensions of microbial biodiversity across domains SO BMC MICROBIOLOGY LA English DT Article DE Diversity indices; Diversity profiles; Phylogenetic diversity; Effective numbers; Community similarity ID PHYLOGENETIC DIVERSITY; SEQUENCING DATA; HIGH-THROUGHPUT; SPECIES CONCEPT; LARGE-SCALE; DEEP-SEA; COMMUNITIES; IDENTIFICATION; RECOGNITION; ALIGNMENTS AB Background: Microbial ecologists often employ methods from classical community ecology to analyze microbial community diversity. However, these methods have limitations because microbial communities differ from macro-organismal communities in key ways. This study sought to quantify microbial diversity using methods that are better suited for data spanning multiple domains of life and dimensions of diversity. Diversity profiles are one novel, promising way to analyze microbial datasets. Diversity profiles encompass many other indices, provide effective numbers of diversity (mathematical generalizations of previous indices that better convey the magnitude of differences in diversity), and can incorporate taxa similarity information. To explore whether these profiles change interpretations of microbial datasets, diversity profiles were calculated for four microbial datasets from different environments spanning all domains of life as well as viruses. Both similarity-based profiles that incorporated phylogenetic relatedness and naive (not similarity-based) profiles were calculated. Simulated datasets were used to examine the robustness of diversity profiles to varying phylogenetic topology and community composition. Results: Diversity profiles provided insights into microbial datasets that were not detectable with classical univariate diversity metrics. For all datasets analyzed, there were key distinctions between calculations that incorporated phylogenetic diversity as a measure of taxa similarity and naive calculations. The profiles also provided information about the effects of rare species on diversity calculations. Additionally, diversity profiles were used to examine thousands of simulated microbial communities, showing that similarity-based and naive diversity profiles only agreed approximately 50% of the time in their classification of which sample was most diverse. This is a strong argument for incorporating similarity information and calculating diversity with a range of emphases on rare and abundant species when quantifying microbial community diversity. Conclusions: For many datasets, diversity profiles provided a different view of microbial community diversity compared to analyses that did not take into account taxa similarity information, effective diversity, or multiple diversity metrics. These findings are a valuable contribution to data analysis methodology in microbial ecology. C1 [Doll, Hannah M.; Armitage, David W.; Daly, Rebecca A.; Emerson, Joanne B.; Goltsman, Daniela S.

Results: We solved structures of two Thermobifida fusca Cel6B (TfuCel6B) cellobiohydrolase mutants and examined ligand dynamics and product release with simulation. Conclusion: These results suggest mechanisms for product release in TfuCel6B. Significance: This study further elucidates the mechanism of a unique cellobiohydrolase with an extended, enclosed active site tunnel. Cellobiohydrolases (CBHs) are typically major components of natural enzyme cocktails for biomass degradation. Their active sites are enclosed in a tunnel, enabling processive hydrolysis of cellulose chains. Glycoside hydrolase Family 6 (GH6) CBHs act from nonreducing ends by an inverting mechanism and are present in many cellulolytic fungi and bacteria. The bacterial Thermobifida fusca Cel6B (TfuCel6B) exhibits a longer and more enclosed active site tunnel than its fungal counterparts. Here, we determine the structures of two TfuCel6B mutants co-crystallized with cellobiose, D274A (catalytic acid), and the double mutant D226A/S232A, which targets the putative catalytic base and a conserved serine that binds the nucleophilic water. The ligand binding and the structure of the active site are retained when compared with the wild type structure, supporting the hypothesis that these residues are directly involved in catalysis. One structure exhibits crystallographic waters that enable construction of a model of the alpha-anomer product after hydrolysis. Interestingly, the product sites of TfuCel6B are completely enclosed by an "exit loop" not present in fungal GH6 CBHs and by an extended "bottom loop". From the structures, we hypothesize that either of the loops enclosing the product subsites in the TfuCel6B active site tunnel must open substantially for product release. With simulation, we demonstrate that both loops can readily open to allow product release with equal probability in solution or when the enzyme is engaged on cellulose. Overall, this study reveals new structural details of GH6 CBHs likely important for functional differences among enzymes from this important family.

TI Perched-water analysis related to deep vadose zone contaminant transport and impact to groundwater SO JOURNAL OF HYDROLOGY LA English DT Article DE Perched water; Deep vadose zone; Contaminant transport; Groundwater contaminant flux ID UNSATURATED ZONE; PAJARITO PLATEAU; YUCCA MOUNTAIN; LOS-ALAMOS; NEW-MEXICO; FLOW; SUBSURFACE; BENEATH; TRACER AB A series of calculations and model predictions were used to evaluate the controls on perched-water conditions and constraints on perching occurrence, persistence, and potential impact on groundwater contamination. These simulations considered perched-water conditions that have been observed in the vadose zone above a fine-grained layer located just a few meters above the water table beneath the B-Complex Tank Farms area at the Hanford Site. The perched water, containing elevated concentrations of uranium and technetium-99, is important to consider in evaluating the future flux of contaminated water into the groundwater. A study was conducted to examine the perched-water conditions and quantitatively evaluate (I) factors that control perching behavior, (2) contaminant flux toward groundwater, and, (3) associated groundwater impact. Based on the current vertical transport pathways and large areal extent of the perched system, the evaluation was conducted using a one-dimensional analysis. Steady-state analytical calculations showed that the perching-layer hydraulic conductivity is likely to be up to two orders of magnitude lower than the value obtained from Hanford site material property estimates. Numerical flow and transport simulations provided both steady-state and transient system estimates of water and contaminant behavior and were used to further refine the range of conditions consistent with current observations of perched water height and to provide estimates of future water and contaminant flux to groundwater. Near-term removal of perched water by pumping can decrease the total contaminant mass that will discharge to the groundwater, but will have only a moderate effect on the near-term discharge rate and corresponding contaminant concentration in groundwater. Combining pumping with a decrease in the recharge rate will be most effective in minimizing the impact to groundwater. These results provide a framework for constraining the behavior of perched aquifer systems especially related to impacts on contaminant transport. (C) 2013 Elsevier B.V. All rights reserved.

TI Recommendations following a multi-laboratory comparison of microbial source tracking methods SO WATER RESEARCH LA English DT Article DE Microbial source tracking; qPCR; Water quality; Coliform ID BACTEROIDALES GENETIC-MARKERS; BOVINE FECAL POLLUTION; TIME QUANTITATIVE PCR; REAL-TIME; WATER-QUALITY; FRESH-WATER; RECREATIONAL WATER; ASSAYS; PERFORMANCE; RNA AB Microbial source tracking (MST) methods were evaluated in the Source Identification Protocol Project (SIPP), in which 27 laboratories compared methods to identify host sources of fecal pollution from blinded water samples containing either one or two different fecal types collected from California. This paper details lessons learned from the SIPP study and makes recommendations to further advance the field of MST. Overall, results from the SIPP study demonstrated that methods are available that can correctly identify whether particular host sources including humans, cows and birds have contributed to contamination in a body of water. However, differences between laboratory protocols and data processing affected results and complicated interpretation of MST method performance in some cases. This was an issue particularly for samples that tested positive (non-zero C-t values) but below the limits of quantification or detection of a PCR assay. Although false positives were observed, such samples in the SIPP study often contained the fecal pollution source that was being targeted, i.e., the samples were true positives. Given these results, and the fact that MST often requires detection of targets present in low concentrations, we propose that such samples be reported and identified in a unique category to facilitate data analysis and method comparisons. Important data can be lost when such samples are simply reported as positive or negative. Actionable thresholds were not derived in the SIPP study due to limitations that included geographic scope, age of samples, and difficulties interpreting low concentrations of target in environmental samples. Nevertheless, the results of the study support the use of MST for water management, especially to prioritize impaired waters in need of remediation. Future integration of MST data into quantitative microbial risk assessments and other models could allow managers to more efficiently protect public health based on site conditions.

TI Evaluation of molecular community analysis methods for discerning fecal sources and human waste SO WATER RESEARCH LA English DT Article DE Microbial source tracking; Microbial community analysis; TRFLP; PhyloChip; Next generation sequencing ID MICROBIAL SOURCE TRACKING; 16S RIBOSOMAL-RNA; DIVERSITY; WATER AB Molecular microbial community analyses provide information on thousands of microorganisms simultaneously, and integrate biotic and abiotic perturbations caused by fecal contamination entering water bodies. A few studies have explored community methods as emerging approaches for microbial source tracking (MST), however, an evaluation of the current state of this approach is lacking. Here, we utilized three types of community-based methods with 64 blind, single- or dual-source, challenge samples generated from 12 sources, including: humans (feces), sewage, septage, dogs, pigs, deer, horses, cows, chickens, gulls, pigeons, and geese. Each source was a composite from multiple donors from four representative geographical regions in California. Methods evaluated included terminal restriction fragment polymorphism (TRFLP), phylogenetic microarray (PhyloChip), and next generation (Illumina) sequencing. These methods correctly identified dominant (or sole) sources in over 90% of the challenge samples, and exhibited excellent specificity regardless of source, rarely detecting a source that was not present in the challenge sample. Sensitivity, however, varied with source and community analysis method. All three methods distinguished septage from human feces and sewage, and identified deer and horse with 100% sensitivity and 100% specificity. Method performance improved if the composition of blind dual-source reference samples were defined by DNA contribution of each single source within the mixture, instead of by Enterococcus colony forming units. Data analysis approach also influenced method performance, indicating the need to standardize data interpretation. Overall, results of this study indicate that community analysis methods hold great promise as they may be used to identify any source, and they are particularly useful for sources that currently do not have, and may never have, a source-specific single marker gene.

Here, we evaluated ten of these methods (BacH, BacHum-UCD, Bacteroides thetaiotaomicron (BtH), BsteriF1, gyrB, HF183 endpoint, HF183 SYBR, HF183 Taqman (R), HumM2, and Methanobrevibacter smithii nifH (Mnif)) using 64 blind samples prepared in one laboratory. The blind samples contained either one or two fecal sources from human, wastewater or non-human sources. The assay results were assessed for presence/absence of the human markers and also quantitatively while varying the following: 1) classification of samples that were detected but not quantifiable (DNQ) as positive or negative; 2) reference fecal sample concentration unit of measure (such as culturable indicator bacteria, wet mass, total DNA, etc); and 3) human fecal source type (stool, sewage or septage). Assay performance using presence/absence metrics was found to depend on the classification of DNQ samples. The assays that performed best quantitatively varied based on the fecal concentration unit of measure and laboratory protocol. All methods were consistently more sensitive to human stools compared to sewage or septage in both the presence/absence and quantitative analysis. Overall, HF183 Taqman (R) was found to be the most effective marker of human fecal contamination in this California-based study. (C) 2013 Elsevier Ltd. All rights reserved.

The results of the Source Identification Protocol Project (SIPP) are presented in a series of papers that cover 41 MST methods. This contribution details the results of the virus and bacteriophage methods targeting human fecal or sewage contamination. Human viruses used as source identifiers included adenoviruses (HAdV), enteroviruses (EV), norovirus Groups I and II (NoVI and NoVII), and polyomaviruses (HPyVs). Bacteriophages were also employed, including somatic coliphages and F-specific RNA bacteriophages (FRNAPH) as general indicators of fecal contamination. Bacteriophage methods targeting human fecal sources included genotyping of FRNAPH isolates and plaque formation on bacterial hosts Enterococcus faecium MB-55, Bacteroides HB-73 and Bacteroides GB-124. The use of small sample volumes (<= 50 ml) resulted in relatively insensitive theoretical limits of detection (10-50 gene copies or plaques x 50 ml(-1)) which, coupled with low virus concentrations in samples, resulted in high false-negative rates, low sensitivity, and low negative predictive values. On the other hand, the specificity of the human virus methods was generally close to 100% and positive predictive values were similar to 40-70% with the exception of NoVs, which were not detected. The bacteriophage methods were generally much less specific toward human sewage than virus methods, although FRNAPH II genotyping was relatively successful, with 18% sensitivity and 85% specificity. While the specificity of the human virus methods engenders great confidence in a positive result, better concentration methods and larger sample volumes must be utilized for greater accuracy of negative results, i.e. the prediction that a human contamination source is absent.

We attempt to bridge the gap between laboratory-scale and larger scale biodiesel production by using cultivation and harvesting data from a commercial algae producer with similar to 1000 m(2) production area (the base case), and compare that with a hypothetical scaled up facility of 101,000 m(2) (the future case). Extraction and separation data are from Solution Recovery Services, Inc. Conversion and combustion data are from the Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation Model (GREET). The LCA boundaries are defined as "pond-to-wheels". Environmental impacts are quantified as NER (energy in/ energy out), global warming potential, photochemical oxidation potential, water depletion, particulate matter, and total NOx and SOx. The functional unit is 1 MJ of energy produced in a passenger car. Results for the base case and the future case show an NER of 33.4 and 1.37, respectively and GWP of 2.9 and 0.18 kg CO2-equivalent, respectively. In comparison, petroleum diesel and soy diesel show an NER of 0.18 and 0.80, respectively and GWP of 0.12 and 0.025, respectively. A critical feature in this work is the low algal productivity (3 g/m(2)/day) reported by the commercial producer, relative to the much higher productivities (20-30 g/m(2)/day) reported by other sources. Notable results include a sensitivity analysis showing that algae with an oil yield of 0.75 kg oil/kg dry biomass in the future case can bring the NER down to 0.64, more comparable with petroleum diesel and soy biodiesel. An important assumption in this work is that all processes are fully co-located and that no transport of intermediate or final products from processing stage to stage is required.

An understanding of the structural and dynamic features that cellulases utilize to bind a single strand of crystalline cellulose and hydrolyze the beta-1,4-glycosidic bonds of cellulose to produce fermentable sugars would greatly facilitate the engineering of improved cellulases for the large-scale conversion of plant biomass. Endoglucanase D (EngD) from Clostridium cellulovorans is a modular enzyme comprising an N-terminal catalytic domain and a C-terminal carbohydrate-binding module, which is attached via a flexible linker. Here, we present the 2.1-angstrom-resolution crystal structures of full-length EngD with and without cellotriose bound, solution small-angle X-ray scattering (SAXS) studies of the full-length enzyme, the characterization of the active cleft glucose binding subsites, and substrate specificity of EngD on soluble and insoluble polymeric carbohydrates. SAXS data support a model in which the linker is flexible, allowing EngD to adopt an extended conformation in solution. The cellotriose-bound EngD structure revealed an extended active-site cleft that contains seven glucose-binding subsites, but unlike the majority of structurally determined endocellulases, the active-site cleft of EngD is partially enclosed by Trpl 62 and Tyr232. EngD variants, which lack Trp162, showed a significant reduction in activity and an alteration in the distribution of cellohexaose degradation products, suggesting that Trpl 62 plays a direct role in substrate binding.

CENP-E features a well-characterized kinesin motor domain at its N-terminus and a second microtubule-binding domain at its C-terminus of unknown function. CENP-F is important for the formation of proper kinetochore-microtubule attachment and, similar to CENP-E, contains two microtubule-binding domains at its termini. While the importance of these proteins is known, the details of their interactions with microtubules have not yet been investigated. We have biochemically and structurally characterized the microtubule-binding properties of the amino- and carboxyl-terminal domains of CENP-F as well as the carboxyl-terminal (non-kinesin) domain of CENP-E. CENP-E's C-terminus and CENP-F's N-terminus bind microtubules with similar affinity to the well-characterized Ndc80 complex, while CENP-F's C-terminus shows much lower affinity. Electron microscopy analysis reveals that all of these domains engage the microtubule surface in a disordered manner, suggesting that these factors have no favored binding geometry and may allow for initial side-on attachments early in mitosis.

TI Integration of stable isotope and trace contaminant concentration for enhanced forensic acetone discrimination SO TALANTA LA English DT Article DE Stable isotope; Forensic fingerprinting; Acetone; Trace contaminant analysis ID MASS-SPECTROMETRY; PRECURSOR AB We analyzed 21 neat acetone samples from 15 different suppliers to demonstrate the utility of a coupled stable isotope and trace contaminant strategy for distinguishing forensically-relevant samples. By combining these two pieces of orthogonal data we could discriminate all of the acetones that were produced by the 15 different suppliers. Using stable isotope ratios alone, we were able to distinguish 8 acetone samples, while the remaining 13 fell into four clusters with highly similar signatures. Adding trace chemical contaminant information enhanced discrimination to 13 individual acetones with three residual clusters. The acetones within each cluster shared a common manufacturer and might, therefore, not be expected to be resolved. The data presented here demonstrates the power of combining orthogonal data sets to enhance sample fingerprinting and highlights the role disparate data could play in future forensic investigations.

This work presents a simple and sensitive method for sampling and analysis of ROS using a packed column coated with a profluorescent nitroxide scavenger, proxyl fluorescamine (PF). Quantification was performed by extraction and analysis using HPLC with fluorescence detection. For comparison, the conventional method of collecting aerosols into dichlorofluorescin (DCFH) aqueous solution was used as a reference. The method was successfully applied to the determination of ROS in a model secondary organic aerosol (SOA) system generated by ozonolysis of nicotine, as well as in secondhand tobacco smoke (SHS). ROS concentrations between 50-565 nmol m(-3) were detected in fresh SOA and SHS samples. After SHS aging for 22 h, 13-18% of the initial ROS mass remained, suggesting the presence of persistent ROS. The new method offers better stability and reproducibility along with sensitivity comparable to that of DCFH (method detection limit of 3.2 and 1.4 nmol m(-3) of equivalent H2O2 for PF and DCFH respectively). The PF probe was stable during storage at room temperature and not reactive with ozone or NO, whereas DCFH in the particle-collecting liquid system was strongly influenced by ozone and NO,, interferences. This case study provides a good basis for employing solid-phase supported PF for field measurement of specific ROS in other combustion systems (i.e. biomass burning, candles, and diesel exhaust) and environmental aerosols.

Thus, there is a great global health need for development of antimicrobial countermeasures that target novel cell molecules or processes. RNA represents a largely unexploited category of potential targets for antimicrobial design. For decades, control of cellular behavior was thought to be the exclusive purview of protein-based regulators. The recent discovery of small RNAs (sRNAs) as a universal class of powerful RNA-based regulatory biomolecules has the potential to revolutionize our understanding of gene regulation in practically all biological functions. In general, sRNAs regulate gene expression by base-pairing with multiple downstream target mRNAs to prevent translation of mRNA into protein. In this review, we will discuss recent studies that document discovery of bacterial, viral, and human sRNAs and their molecular mechanisms in regulation of pathogen virulence and host immunity. Illuminating the functional roles of sRNAs in virulence and host immunity can provide the fundamental knowledge for development of next-generation antibiotics using sRNAs as novel targets.

To fully utilize the information obtained from these three measurement dimensions, informatics tools based on the accurate mass and time tag methodology were modified to incorporate ion mobility spectrometry drift times for peptides observed in human serum. In this work a reference human serum database was created for 12,139 peptides and populated with the monoisotopic mass, liquid chromatography normalized elution time, and ion mobility spectrometry drift time(s) for each. We demonstrate that the use of three dimensions for peak matching during the peptide identification process resulted in an increased numbers of identifications and a lower false discovery rate relative to only using the mass and normalized elution time dimensions.

Four separate solutions of polyoxometalates (POMs) were prepared using all possible combinations of the tetraethylammonium [(C2H5)(4)N+] cation, chloride (Cl-) heteroanion, tetrabutylammonium [(C4H9)(4)N+] cation and acetate (CH3CO2-) heteroanion. Employing electrospray ionization combined with high-resolution mass spectrometry (ESI-MS) we demonstrate that POM solutions synthesized using the small [(C2H5)(4)N+] cation and Cl- heteroanion are composed predominately of large doubly and triply charged chlorine containing species with a size distribution centered at 14 vanadium atoms. POM solutions prepared using the Cl- anion and a larger [(C4H9)(4)N+] cation are shown to contain slightly larger species with 15 and 16 vanadium atoms, thereby indicating that the size of the ammonium cation exerts only a weak influence on the size of polyoxovanadates formed in solution. POM solutions prepared using (C2H5)(4)NCl and (C4H9)(4)NCl also produced peaks consistent with the attachment of one and two ammonium cations to the larger vanadium oxide species. Solutions prepared using the large (CHCO2-)-C-3 heteroanion, in contrast, contain much smaller singly and doubly charged species with a size distribution centered at six vanadium atoms. In addition, while incorporation of one and two ammonium cations into the smaller vanadium oxide species was observed, no POMs containing the CH3CO2- heteroanion were identified. The gas-phase fragmentation pathways of representative POMs containing one and two ammonium cations were examined using collision induced dissociation (CID) and mass spectrometry. Similar primary fragmentation pathways involving partial loss of the ammonium cation were observed for species containing both one and two ammonium cations largely independent of the size, composition and charge state of the precursor ion. The [(C4H9)N+] was found to exhibit stronger interactions with the core of the POMs resulting in higher abundance of fragment ions containing (C4H9) units compared to (C2H5) units originating from [(C2H5)(4)N+]. These results provide fundamental insight into the interactions between anionic metal oxides, heteroanions and ammonium cations that are responsible for the size and composition-controlled synthesis of POMs in solution.

In this talk, I will discuss some of the unique phenomena that occur when particles with TeV energies and above interact with matter. The emphasis will be on lepton interactions. The cross-sections for electron bremsstrahlung and photon pair conversion are suppressed at high energies, by the Landau-Pomeranchuk-Migdal (LPM) effect, lengthening electromagnetic showers. At still higher energies (above 10(20) eV), photonuclear and electronuclear interactions dominate, and showers become predominantly hadronic. Muons interact much less strongly, so can travel long distances through solids before losing energy. Tau leptons behave similarly, although their short lifetime limits how far they can travel. The hadronic interaction cross-section is believed to continue to increase slowly with rising energy; measurements of cosmic-ray air showers seem to confirm this prediction. (C) 2013 Elsevier B.V.

These irradiation conditions reveal the effect of the collision cascade density on ion-induced swelling and roughening of the GaN surface. Results show that, for F and P ions that create dilute collision cascades, swelling dominates erosion. In the case of molecular ion irradiation, characterized by larger cascade densities, surface erosion dominates swelling. For the conditions studied, surface roughness scales with the thickness of surface amorphous layers when these layers are thinner than about 20 nm. (C) 2013 Elsevier B.V. All rights reserved.

This accelerator is designed to deliver intense (up to 3 x 10(11) ions/pulse), 0.6 to similar to 600 ns duration pulses of 0.05-1.2 MeV lithium ions at a rate of about 2 pulses per minute onto 1-10 mm scale target areas. When focused to mm-diameter spots, the beam is predicted to volumetrically heat micrometer thick foils to temperatures of similar to 30,000 degrees K. At lower beam power densities, the short excitation pulse with tunable intensity and time profile enables pump-probe type studies of defect dynamics in a broad range of materials. We briefly describe the accelerator concept and design, present results from beam pulse shaping experiments and discuss examples of pump-probe type studies of defect dynamics following irradiation of materials with intense, short ion beam pulses from NDCX-II.

One arm of the interferometer is modulated in optical delay to produce dynamic interference fringes. Fringe visibility and the two individual intensities are measured nearly simultaneously to allow direct calculation of the modulus of the complex degree of coherence as a function of the lateral shear between the two interferometer arms. Spatial degree of coherence is measured for a step-index MMF pumped with monochromatic and broadband optical sources.

TI Split-probe hybrid femtosecond/picosecond rotational CARS for time-domain measurement of S-branch Raman linewidths within a single laser shot SO OPTICS LETTERS LA English DT Article ID GAS-PHASE THERMOMETRY; SCATTERING; SPECTROSCOPY; TEMPERATURE; FLAMES AB We introduce a multiplex technique for the single-laser-shot determination of S-branch Raman linewidths with high accuracy and precision by implementing hybrid femtosecond (fs)/picosecond (ps) rotational coherent anti-Stokes Raman spectroscopy (CARS) with multiple spatially and temporally separated probe beams derived from a single laser pulse. The probe beams scatter from the rotational coherence driven by the fs pump and Stokes pulses at four different probe pulse delay times spanning 360 ps, thereby mapping collisional coherence dephasing in time for the populated rotational levels. The probe beams scatter at different folded BOXCARS angles, yielding spatially separated CARS signals which are collected simultaneously on the charge coupled device camera. The technique yields a single-shot standard deviation (1 sigma) of less than 3.5% in the determination of Raman linewidths and the average linewidth values obtained for N-2 are within 1% of those previously reported. The presented technique opens the possibility for correcting CARS spectra for time-varying collisional environments in operando.

TI Cylindrical quasi-Gaussian beams SO OPTICS LETTERS LA English DT Article ID FRACTIONAL TYPE ALPHA; VECTOR WAVE ANALYSIS; BESSEL VORTEX BEAM; COMPLEX-SOURCE; EVANESCENT WAVES; POINT; RAYS; DIFFRACTION; FIELDS; MODES AB Making use of the complex-source-point method in cylindrical coordinates, an exact solution representing a cylindrical quasi-Gaussian beam of arbitrary waist w(0) satisfying both the Helmholtz and Maxwell's equations is introduced. The Cartesian components of the electromagnetic field are derived stemming from different polarizations of the magnetic and electric vector potentials based on Maxwell's vectorial equations and Lorenz's gauge condition, without any approximations. Computations illustrate the theory for tightly focused and quasi-collimated cylindrical beams. The results are particularly useful in beam-forming design using high-aperture or collimated cylindrical laser beams in imaging microscopy, particle manipulation, optical tweezers, and the study of scattering, radiation forces, and torque on cylindrical structures.

The mitotic spindle presents a central example of this flexibility, scaling with the dimensions of the cell to mediate accurate chromosome segregation. To determine whether spindle size regulation is achieved through a developmental program or is intrinsically specified by cell size or shape, we developed a system to encapsulate cytoplasm from Xenopus eggs and embryos inside cell-like compartments of defined sizes. Spindle size was observed to shrink with decreasing compartment size, similar to what occurs during early embryogenesis, and this scaling trend depended on compartment volume rather than shape. Thus, the amount of cytoplasmic material provides a mechanism for regulating the size of intracellular structures.

We have studied the compressibility and spin state of Fe in Al-bearing phase D up to 90 GPa using synchrotron X-ray diffraction and X-ray emission spectroscopy. Fe-Al-bearing phase D was synthesized at 25 GPa and 1400 degrees C with approximate composition MgSi1.5Fe0.15Al0.32H2.6O6, where nearly all of the Fe is ferric (Fe3+). Analysis of Fe-K beta emission spectra reveals a gradual, pressure-induced high-spin (HS) to low-spin (LS) transition of Fe3+ extending from 40 to 65 GPa. The fitted equation of state for high-spin Fe-Al-bearing phase D results in a bulk modulus K-T0 = 147(2) GPa with pressure derivative K' = 6.3(3). An equation of state over the entire pressure range was calculated using the observed variation in low-spin fraction with pressure and a low-spin bulk modulus of K-T0 = 253(30) GPa, derived from the data above 65 GPa. Pronounced softening in the bulk modulus occurs during the spin transition, reaching a minimum at 50 GPa (similar to 1500 km) where the bulk modulus of Fe-Al phase D is about 35% lower than Fe-Al-bearing silicate perovskite. Recovery of the bulk modulus at 50-65 GPa results in a structure that has a similar incompressibility as silicate perovskite above 65 GPa. Similarly, the bulk sound velocity of Fe-Al phase D reaches a minimum at similar to 50 GPa, being about 10% slower than silicate perovskite. The potential association of Fe-Al phase D with subducted slabs entering the lower mantle, along with its elastic properties through the Fe3+ spin transition predicted at 1200-1800 km, suggests that phase D may provide an alternative explanation for small-scale mid-lower mantle seismic scatterers and supports the presence of deeply recycled sediments in the lower mantle.

TI Warming and glacier recession in the Rakaia valley, Southern Alps of New Zealand, during Heinrich Stadial 1 SO EARTH AND PLANETARY SCIENCE LETTERS LA English DT Article DE Be-10; surface-exposure dating; snowline; Last Glacial termination; Subtropical Front; Southern Ocean ID NUCLIDE PRODUCTION-RATES; BE-10 PRODUCTION-RATE; NZ-INTIMATE PROJECT; FRANZ-JOSEF GLACIER; LAST DEGLACIATION; ATMOSPHERIC CO2; CLIMATE SENSITIVITY; RADIOCARBON CHRONOLOGY; MAXIMUM CLIMATE; BIPOLAR SEESAW AB The termination of the last ice age featured a major reconfiguration of Earth's climate and cryosphere, yet the underlying causes of these massive changes continue to be debated. Documenting the spatial and temporal variations of atmospheric temperature during deglaciation can help discriminate among potential drivers. Here, we present a Be-10 surface-exposure chronology and glaciological reconstruction of ice recession following the Last Glacial Maximum (LGM) in the Rakaia valley, Southern Alps of New Zealand. Innermost LGM moraines at Big Ben have an age of 17,840 +/- 240 yrs, whereas ice-marginal moraines or ice-molded bedrock surfaces at distances up-valley from Big Ben of 12.5 km (Lake Coleridge), similar to 25 km (Castle Hill), similar to 28 km (Double Hill), similar to 43 km (Prospect Hill), and similar to 58 km (Reischek knob) have ages of 17,020 +/- 70 yrs, 17,100 +/- 110 yrs, 16,960 +/- 370 yrs, 16,250 +/- 340 yrs, and 15,660 +/- 160 yrs, respectively. These results indicate extensive recession of the Rakaia glacier, which we attribute primarily to the effects of climatic warming. In conjunction with geomorphological maps and a glaciological reconstruction for the Rakaia valley, we use our chronology to infer timing and magnitude of past atmospheric temperature changes. Compared to an overall temperature rise of similar to 4.65 degrees C between the end of the LGM and the start of the Holocene, the glacier recession between similar to 17,840 and similar to 15,660 yrs ago is attributable to a net temperature increase of similar to 4.0 degrees C (from -6.25 to -2.25 degrees C), accounting for similar to 86% of the overall warming. Approximately 3.75 degrees C (similar to 70%) of the warming occurred between similar to 17,840 and similar to 16,250 yrs ago, with a further 0.75 degrees C (similar to 16%) increase between similar to 16,250 and similar to 15,660 yrs ago. A sustained southward shift of the Subtropical Front (STF) south of Australia between similar to 17,800 and similar to 16,000 yrs ago coincides with the warming over the Rakaia valley, and suggests a close link between Southern Ocean frontal boundary positions and southern mid-latitude climate. Most of the deglacial warming in the Southern Alps occurred during the early part of Heinrich Stadial 1 (HS1) of the North Atlantic region. Because the STF is associated with the position of the westerly wind belt, our findings support the concept that a southward shift of Earth's wind belts accompanied the early part of HS1 cooling in the North Atlantic, leading to warming and deglaciation in southern middle latitudes.

Small-angle solution X-ray scattering, crystallography, and electron microscopy (EM) reconstructions revealed that partial ATP occupancy caused the heptameric closed ring of the bacterial enhancer-binding protein (bEBP) NtrC1 to rearrange into a hexameric split ring of striking asymmetry. The highly conserved and functionally crucial GAFTGA loops responsible for interacting with sigma 54-RNA polymerase formed a spiral staircase. We propose that splitting of the ensemble directs ATP hydrolysis within the oligomer, and the ring's asymmetry guides interaction between ATPase and the complex of sigma 54 and promoter DNA. Similarity between the structure of the transcriptional activator NtrC1 and those of distantly related helicases Rho and E1 reveals a general mechanism in homomeric ATPases whereby complex allostery within the ring geometry forms asymmetric functional states that allow these biological motors to exert directional forces on their target macromolecules.

TI Nonequilibrium thermal transport and its relation to linear response SO PHYSICAL REVIEW B LA English DT Article ID FINITE-TEMPERATURE; HEISENBERG-MODEL; LUTTINGER LIQUID; HEAT-CONDUCTION; CHAIN; SYSTEM; WIRE AB We study the real-time dynamics of spin chains driven out of thermal equilibrium by an initial temperature gradient T-L not equal T-R using density matrix renormalization group methods. We demonstrate that the nonequilibrium energy current saturates fast to a finite value if the linear-response thermal conductivity is infinite, i.e., if the Drude weight D is nonzero. Our data suggest that a nonintegrable dimerized chain might support such dissipationless transport (D > 0). We show that the steady-state value J(E) of the current for arbitrary T-L not equal T-R is of the functional form J(E) = f(T-L) - f(T-R), i.e., it is completely determined by the linear conductance. We argue for this functional form, which is essentially a Stefan-Boltzmann law in this integrable model; for the XXX ferromagnet, f can be computed via the thermodynamic Bethe ansatz in good agreement with the numerics. Inhomogeneous systems exhibiting different bulk parameters as well as Luttinger liquid boundary physics induced by single impurities are discussed briefly. C1 [Karrasch, C.; Ilan, R.; Moore, J.

It is observed that an electric field applied away from the equilibrium polarization direction causes a stiffening of the transverse acoustic (TA) phonon branch and consequently increases interaction between the TA and the transverse optic soft mode for a range of wave vectors extending from the Brillouin zone center. This provides a direct lattice dynamics mechanism for enhanced electromechanical coupling, and could act as a guide for designing improved piezoelectric materials.

TI Electromagnetic properties of the 2(1)(+) state in Te-134: Influence of core excitation on single-particle orbits beyond Sn-132 SO PHYSICAL REVIEW C LA English DT Article ID FACILITY AB The g factor and B(E2) of the first excited 2(+) state have been measured following Coulomb excitation of the neutron-rich semimagic nuclide Te-134 (two protons outside Sn-132) produced as a radioactive beam. The precision achieved matches related g-factor measurements on stable beams and distinguishes between alternative models. The B(E2) measurement exposes quadrupole strength in the 2(1)(+) state beyond that predicted by current large-basis shell-model calculations. This additional quadrupole strength can be attributed to coupling between the two valence protons and excitations of the Sn-132 core. However, the wave functions of the low-excitation positive-parity states in Te-134 up to 6(1)(+) remain dominated by the pi((g7/2))(2) configuration. C1 [Stuchbery, A.

We investigate in real time the growth mechanisms of lead dendrites as deposited on the electrodes under an applied potential. TEM images reveal that lead dendrites are developed by the fast protrusion of lead branches in the electrolyte and tip splitting. And, the fast growing tip of the dendritic branch is composed of polycrystalline nanograins and it develops into a single crystalline branch eventually. This study demonstrated unique electrochemical growth of single crystal dendrites through nucleation, aggregation, alignment and attachment of randomly oriented small grains. Additionally, we found the lead concentration in the electrolyte drastically influences the morphology of dendritic formation.

TI GIM(3)E: condition-specific models of cellular metabolism developed from metabolomics and expression data SO BIOINFORMATICS LA English DT Article ID SALMONELLA-TYPHIMURIUM; ESCHERICHIA-COLI; FLUX ANALYSIS; VIRULENCE; NETWORK; RECONSTRUCTIONS; TEMPERATURE; PROTEOMICS; DISCOVERY; INFECTION AB Motivation: Genome-scale metabolic models have been used extensively to investigate alterations in cellular metabolism. The accuracy of these models to represent cellular metabolism in specific conditions has been improved by constraining the model with omics data sources. However, few practical methods for integrating metabolomics data with other omics data sources into genome-scale models of metabolism have been developed. Results: GIM(3)E (Gene Inactivation Moderated by Metabolism, Metabolomics and Expression) is an algorithm that enables the development of condition-specific models based on an objective function, transcriptomics and cellular metabolomics data. GIM(3)E establishes metabolite use requirements with metabolomics data, uses model-paired transcriptomics data to find experimentally supported solutions and provides calculations of the turnover (production/consumption) flux of metabolites. GIM(3)E was used to investigate the effects of integrating additional omics datasets to create increasingly constrained solution spaces of Salmonella Typhimurium metabolism during growth in both rich and virulence media. This integration proved to be informative and resulted in a requirement of additional active reactions (12 in each case) or metabolites (26 or 29, respectively). The addition of constraints from transcriptomics also impacted the allowed solution space, and the cellular metabolites with turnover fluxes that were necessarily altered by the change in conditions increased from 118 to 271 of 1397.

TI Molecular Mechanisms of HIV Type 1 Prophylaxis Failure Revealed by Single-Genome Sequencing SO JOURNAL OF INFECTIOUS DISEASES LA English DT Article DE HIV-1 transmission; occupational exposure; post-exposure prophylaxis; multiple virus transmission; single genome sequencing; virus sequestration ID INFECTION; SEROCONVERSION; PREVENTION AB Trials of human immunodeficiency virus type 1 (HIV) pre- and postexposure prophylaxis show promise. Here, we describe a novel strategy for deciphering mechanisms of prophylaxis failure that could improve therapeutic outcomes. A healthcare worker began antiretroviral prophylaxis immediately after a high-risk needlestick injury but nonetheless became viremic 11 weeks later. Single-genome sequencing of plasma viral RNA identified 15 drug susceptible transmitted/founder HIV genomes responsible for productive infection. Sequences emanating from these genomes exhibited extremely low diversity, suggesting virus sequestration as opposed to low-level replication as the cause of breakthrough infection. Identification of transmitted/founder viruses allows for genome-wide assessment of molecular mechanisms of prophylaxis failure.

The ultimate structural integrity of the weld is fundamentally related to the geometry and local mechanical properties of these zones. Numerical models used in engineering design of structures subjected to extreme loading conditions require validated constitutive models capable of accurately describing the complete local deformation behavior at large plastic strains up to and including failure. The present work presents a numerical and experimental study characterizing the mechanical properties of thick ( > 25 mm) aluminum alloy AA 2139-T8 plates that were joined using FSW techniques. A micro-hardness map of the weld is used to determine the geometry of individual weld zones. Micro-tension specimens of each weld zone are individually tested to develop constitutive models which were validated with a tension experiment of the entire weld. In particular, the failure mechanisms through the thickness of the weld and their relation to the microstructural zones that were formed during the FSW process are examined. (C) 2013 Elsevier B.V.

This work demonstrates that a reaction of sodium hydride with fullerene (C-60) results in the formation of a sodium-doped fullerene capable of reversible hydrogen sorption via a chemisorption mechanism. This material not only demonstrated reversible hydrogen storage over several cycles, it also showed the ability to reabsorb over three times the amount of hydrogen (relative to the hydrogen content of NaH) under optimized conditions. The sodium-doped fullerene was hydrogenated on a pressure composition temperature (PCT) instrument at 275 degrees C while under 100 bar of hydrogen pressure. The hydrogen desorption behavior of this sodium-doped fullerene hydride was observed over a temperature range up to 375 degrees C on the PCT and up to 550 degrees C on the thermogravimetric analysis (TGA). Powder x-ray diffraction verifies the identity of this material as being Na6C60. Characterization of this material by thermal decomposition analysis (e.g. PCT and TGA methods), as well as FT-IR and mass spectrometry, indicates that the hydrogen sorption activity of this material is due to the reversible formation of a hydrogenated fullerene (fullerane). However, the reversible formation of fullerane was found to be greatly enhanced by the presence of sodium. It was also demonstrated that the addition of a catalytic amount of titanium (via TiO2 or Ti(OBu)(4)) further enhances the hydrogen sorption process of the sodium-doped fullerene material.

Goettgens, Berthold TI Single site-specific integration targeting coupled with embryonic stem cell differentiation provides a high-throughput alternative to in vivo enhancer analyses SO BIOLOGY OPEN LA English DT Article DE ES cells; Enhancer; Haematopoiesis; Transcription AB Comprehensive analysis of cis-regulatory elements is key to understanding the dynamic gene regulatory networks that control embryonic development. While transgenic animals represent the gold standard assay, their generation is costly, entails significant animal usage, and in utero development complicates time-course studies. As an alternative, embryonic stem (ES) cells can readily be differentiated in a process that correlates well with developing embryos. Here, we describe a highly effective platform for enhancer assays using an Hsp68/Venus reporter cassette that targets to the Hprt locus in mouse ES cells. This platform combines the flexibility of Gateway (R) cloning, live cell trackability of a fluorescent reporter, low background and the advantages of single copy insertion into a defined genomic locus. We demonstrate the successful recapitulation of tissue-specific enhancer activity for two cardiac and two haematopoietic enhancers. In addition, we used this assay to dissect the functionality of the highly conserved Ets/Ets/Gata motif in the Scl+19 enhancer, which revealed that the Gata motif is not required for initiation of enhancer activity. We further confirmed that Gata2 is not required for endothelial activity of the Scl+19 enhancer using Gata2(-/-) Scl+19 transgenic embryos. We have therefore established a valuable toolbox to study gene regulatory networks with broad applicability. (C) 2013. Published by The Company of Biologists Ltd.

The target phenanthrenes were obtained using both standard thermal-and microwave-assisted synthesis. 4-(6-Chlorophenanthren-2-yl)-2,4-dioxobutanoic acid (18) was the most active compound of the series, inhibiting both 3'-end processing (3'-P) and strand transfer (ST) with IC50 values of 5 and 1.3 mu M, respectively. Docking studies revealed two predominant binding modes that were distinct from the binding modes of raltegravir and elvitegravir, and suggest a novel binding region in the IN active site. Moreover, these compounds are predicted not to interact significantly with some of the key amino acids (Q148 and N155) implicated in viral resistance. Therefore, this series of compounds can further be investigated for a possible chemotype to circumvent resistance to clinical HIV-1 IN inhibitors. (c) 2013 Elsevier Ltd. All rights reserved.

Expression of synthetic heterologous metabolic pathways in a host may not be favorable due to the toxicity of non-native metabolic intermediates and the but of expression of genes in the pathway. Thus, optimization of gene expression is required to prevent accumulation of the toxic metabolites and to minimize burden. In this study, we used the BglBrick standard cloning vectors to optimize expression of genes in a heterologous mevalonate-based isoprenoid biosynthetic pathway and examined their impact on production of amorpha-4,11-diene, an intermediate in the biosynthesis of the antimalarial drug artemisinin. Amorpha-4,11-diene titer increased almost three-fold when HMG-CoA reductase and phosphomevalonate kinase were overexpressed relative to the original engineered pathway. In addition, selected-reaction monitoring (SRM) mass spectrometry-based targeted proteomics showed that overexpression of HMG-CoA reductase and phosphomevalonate kinase significantly enhances the titer of amorpha-4,11-diene, and that further increases in titer could be achieved if mevalonate kinase were engineered as well.

Demand for sustainable products and over a half century of research have led to moderate commercial success of PHA. Yet, these materials are not pervasive. Therefore, an important question to address is, "what is the barrier that prevents widespread application of these materials?" PHA can be made from an incredibly diverse class of monomers that incorporate both simple and complex organic acids. Herein, we provide an updated list of unique PHA monomers that are substrates for a PHA polymerase. Unfortunately, most unique monomers are incorporated only after feeding a structurally related feedstock to a PHA accumulating bacterium. Therefore, we put forward an argument that research must nosy turn to developing feedstock-independent, synthetic pathways to produce an increased diversity of PHAs capable of competing with petroleum-derived plastics.

E. coli DH1 and MG1655, two commonly used metabolic engineering hosts, were both sensitive to the presence of 1,4-BDO in the growth medium, but to different extents. The strains also showed differences in the transcriptional response of the yhjX gene that was highly induced in response to 1,4-BDO, yhjX deletion improved growth of the E. colt strains in the control defined medium but did not significantly impact 1,4-BDO sensitivity. Overexpression of yhjX using a plasmid-borne copy and lactose-inducible promoter also did not result in an improvement in 1,4-BDO tolerance. However, the large differential expression of yhjX in response to this diol provided the foundation to develop a biosensor for the detection of 1,4-BDO using a fluorescent gene under the control of the yhjX promoter. A basic P-yhjX: GFP biosensor in E. coli DH1 allows the detection of 4-7% 1,4-BDO in the extracellular medium and provides a tool for high throughput engineering for improving 1,4-BDO production strains.

TI GaN1-xSbx highly mismatched alloys grown by low temperature molecular beam epitaxy under Ga-rich conditions SO JOURNAL OF CRYSTAL GROWTH LA English DT Article DE Crystal structure; Molecular beam epitaxy; Semiconducting III-V materials; Nitrides AB The electronic structure of the conduction and valence bands of highly mismatched alloys (HMAs) such as GaN1-xSbx are well described by the band anticrossing model. The properties of this alloy, which has a large band gap range and controllable valence band positions, make it a candidate material for efficient solar energy conversion devices. We have examined the growth and structural properties of amorphous and crystalline GaN1-xSbx. These HMAs were grown by low temperature molecular beam epitaxy (MBE) under Ga-rich conditions. While there is a monotonic linear increase of Sb incorporation with Sb overpressure, there was no obvious dependence of Sb incorporation with growth temperature for the range of 10-470 degrees C. At growth temperatures lower than 100 degrees C, GaN1-xSx HMAs lose crystallinity and become amorphous for Sb compositions at or exceeding similar to 5%. Ga-rich growth resulted in strong absorption at energies as low as 1 eV for GaN1-xSbx alloys of all compositions. The strong low energy absorption may arise from a Ga-related defect band.

This algorithm is provided in the Zeo++ software for open use. In this method, ray lengths are depicted as two-dimensional histograms that complement alternate descriptors, such as free and included sphere diameters. We illustrate the specific use of these methods as a tool to narrow the range of zeolites useful for a given catalytic application because of the shape and size of voids. DAC, AFS, AFY, SFO and EON zeolites contain void spaces similar, as suggested by Euclidean distance values between histograms, to those within MOR 8-MR side pockets, which stabilize the transition states that mediate dimethyl ether carbonylation to methyl acetate; these alternate structures offer different connecting void environments, which can enhance or restrict molecular access and influence the effectiveness of the 8-MR protons. NES, EON and USI zeolites exhibit histogram features similar to those of 12-MR MOR channels, where protons selectively catalyze alkylation of biphenyl and naphthalene to 4,4'-diisopropylbiphenyl and 2,6-diisopropylnaphthalene, respectively, with propene. SBT, FAU and SBS contain voids similar in topology to the 12-MR channels of LTL zeolites, within which Pt clusters remain active and stable during the dehydrocyclization of light alkanes, but without the one-dimensional nature of LTL channels. The approach and implementation of these methods are applicable to any microporous or mesoporous solids and to adsorption processes driven by van der Waals contacts between hosts and guest molecules.

TI Formation of crystalline PuO2+x center dot nH(2)O nanoparticles upon sorption of Pu(V,VI) onto hematite SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID CERIUM OXIDE NANOPARTICLES; LATTICE-PARAMETERS; PLUTONIUM; SIZE; REDUCTION; SPECIATION; GOETHITE; WATER; ADSORPTION; DEPENDENCE AB It has been recognized that natural aquatic colloids can readily sorb actinide elements, including plutonium, whose behavior is complicated by its multiple valence states and the possibility of redox reactions under environmental conditions. In this paper, the sorption and surface-mediated redox transformations of hexavalent plutonium on synthetic well-characterized hematite colloids are studied in a series of batch sorption experiments. The variation in the kinetics of the Pu-hematite interactions, Pu-L-3-XAFS, and HRTEM over a broad range of total concentrations of Pu have been studied in an attempt to define the molecular-level speciation of Pu. The surface-mediated slow reduction of Pu(V/VI) results in the formation of crystalline nanoparticles of PuO2+x center dot nH(2)O approximately 1.5 nm in size at [Pu](tot) >= 10(-9) M. This result is confirmed independently by HRTEM images of Pu-containing particles and through the identification in the EXAFS of a Pu neighbor shell at 3.8 angstrom. The formation of such nanoparticles potentially influences the colloid-mediated transport of Pu in the subsurface environment because of the very slow leaching of Pu from the hematite colloids.

At pH 7.0, the reductive dissolution rates of goethite were 3.5 mu moles m(-2) h(-1) by 50 mu M FMNH2 and 0.27 mu moles m(-2) h(-1) by 50 mu M RBFH2; the reductive dissolution rates of hematite were 29 mu moles m(-2) h(-1) by 50 mu M FMNH2 and 151 mu moles m(-2) h(-1) by 50 mu M RBFH2. The extent of reaction was limited by the thermodynamic driving force at circumneutral pH. Both the initial reaction rate and reaction extent increased with decreasing pH. On a unit surface area basis, goethite was less reactive than hematite between pH 4.0 and 7.0. AH(2)DS, the reduced form of the well-studied synthetic electron shuttle anthraquinone-2,6-disulfonate, yielded higher rates than FMNH2 under most reaction conditions. Two additional model compounds, methyl viologen and benzyl viologen, were investigated under similar reaction conditions to explore the relationship between reaction rate and thermodynamic properties. Relevant kinetic data from the literature were also included in the analysis to span a large range in half-cell potentials. Other conditions being equal, the surface area normalized initial reaction rate (r(a)) increased as the redox potential of the reductant became more negative. A non-linear relationship was observed between log r(a) and the redox potential for eight reductants at pH 7.0. When pH and reductant concentration were fixed, log r(a) was positively correlated to the redox potential of four Fe(III) oxides over a wide pH range, following a non-linear relationship as well.

TI Dynamics of basaltic glass dissolution - Capturing microscopic effects in continuum scale models SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID REACTIVE GEOCHEMICAL TRANSPORT; SATURATED FRACTURED ROCKS; NONISOTHERMAL FLUID-FLOW; ISOTOPE FRACTIONATION; MINERAL SEQUESTRATION; RATES; KINETICS; PH; CONSEQUENCES; 25-DEGREES-C AB The method of 'multiple interacting continua' (MINC) was applied to include microscopic rate-limiting processes in continuum scale reactive transport models of basaltic glass dissolution. The MINC method involves dividing the system up to ambient fluid and grains, using a specific surface area to describe the interface between the two. The various grains and regions within grains can then be described by dividing them into continua separated by dividing surfaces. Millions of grains can thus be considered within the method without the need to explicity discretizing them. Four continua were used for describing a dissolving basaltic glass grain; the first one describes the ambient fluid around the grain, while the second, third and fourth continuum refer to a diffusive leached layer, the dissolving part of the grain and the inert part of the grain, respectively. The model was validated using the TOUGHREACT simulator and data from column flow through experiments of basaltic glass dissolution at low, neutral and high pH values. Successful reactive transport simulations of the experiments and overall adequate agreement between measured and simulated values provides validation that the MINC approach can be applied for incorporating microscopic effects in continuum scale basaltic glass dissolution models. Equivalent models can be used when simulating dissolution and alteration of other minerals. The study provides an example of how numerical modeling and experimental work can be combined to enhance understanding of mechanisms associated with basaltic glass dissolution. Column outlet concentrations indicated basaltic glass to dissolve stoichiometrically at pH 3. Predictive simulations with the developed MINC model indicated significant precipitation of secondary minerals within the column at neutral and high pH, explaining observed non-stoichiometric outlet concentrations at these pH levels. Clay, zeolite and hydroxide precipitation was predicted to be most abundant within the column. (c) 2013 Elsevier Ltd. All rights reserved. C1 [Aradottir, E. S.

Rother, Gernot TI Multi-scale characterization of pore evolution in a combustion metamorphic complex, Hatrurim basin, Israel: Combining (ultra) small-angle neutron scattering and image analysis SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID 2-PHASE RANDOM-MEDIA; MATRIX PROBABILITY FUNCTIONS; RECONSTRUCTING RANDOM-MEDIA; X-RAY-SCATTERING; SOURCE ROCKS; MICROSTRUCTURE; GENERATION; FRACTALS; POROSITY; SURFACE AB Backscattered scanning electron micrograph and ultra small- and small-angle neutron scattering data have been combined to provide statistically meaningful data on the pore/grain structure and pore evolution of combustion metamorphic complexes from the Hatrurim basin, Israel. Three processes, anti-sintering roughening, alteration of protolith (dehydration, decarbonation, and oxidation) and crystallization of high-temperature minerals, occurred simultaneously, leading to significant changes in observed pore/grain structures. Pore structures in the protoliths, and in low- and high-grade metamorphic rocks show surface (D-s) and mass (D-m) pore fractal geometries with gradual increases in both Ds and Dm values as a function of metamorphic grade. This suggests that increases in pore volume and formation of less branching pore networks are accompanied by a roughening of pore/grain interfaces. Additionally, pore evolution during combustion metamorphism is also characterized by reduced contributions from small-scale pores to the cumulative porosity in the high-grade rocks. At high temperatures, small-scale pores may be preferentially closed by the formation of high-temperature minerals, producing a rougher morphology with increasing temperature. Alternatively, large-scale pores may develop at the expense of small-scale pores. These observations (pore fractal geometry and cumulative porosity) indicate that the evolution of pore/grain structures is correlated with the growth of high-temperature phases and is a consequence of the energy balance between pore/grain surface energy and energy arising from heterogeneous phase contacts. The apparent pore volume density further suggests that the localized time/temperature development of the high-grade Hatrurim rocks is not simply an extension of that of the low-grade rocks. The former likely represents the "hot spots (burning foci)" in the overall metamorphic terrain while the latter may represent contact aureoles. (c) 2013 Elsevier Ltd. All rights reserved.

TI Sorptive fractionation of organic matter and formation of organo-hydroxy-aluminum complexes during litter biodegradation in the presence of gibbsite SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID ACID FOREST SOILS; X-RAY MICROSCOPY; CHEMICAL-COMPOSITION; DIFFUSE REFLECTANCE; DRIFT SPECTROSCOPY; FULVIC-ACID; HUMIC-ACID; IRON-OXIDE; CARBON; GOETHITE AB Solid and aqueous phase Al species are recognized to affect organic matter (OM) stabilization in forest soils. However, little is known about the dynamics of formation, composition and dissolution of organo-Al hydroxide complexes in microbially-active soil systems, where plant litter is subject to microbial decomposition in close proximity to mineral weathering reactions. We incubated gibbsite-quartz mineral mixtures in the presence of forest floor material inoculated with a native microbial consortium for periods of 5, 60 and 154 days. At each time step, samples were density separated into light (<1.6 g cm(-3)), intermediate (1.6-2.0 g cm(-3)), and heavy (>2.0 g cm(-3)) fractions. The light fraction was mainly comprised of particulate organic matter, while the intermediate and heavy density fractions contained moderate and large amounts of Al-minerals, respectively. Multi-method interrogation of the fractions indicated the intermediate and heavy fractions differed both in mineral structure and organic compound composition. X-ray diffraction analysis and SEM/EDS of the mineral component of the intermediate fractions indicated some alteration of the original gibbsite structure into less crystalline Al hydroxide and possibly proto-imogolite species, whereas alteration of the gibbsite structure was not evident in the heavy fraction. DRIFT, Py-GC/MS and STXM/NEXAFS results all showed that intermediate fractions were composed mostly of lignin-derived compounds, phenolics, and polysaccharides. Heavy fraction organics were dominated by polysaccharides, and were enriched in proteins, N-bearing compounds, and lipids. The source of organics appeared to differ between the intermediate and heavy fractions. Heavy fractions were enriched in C-13 with lower C/N ratios relative to intermediate fractions, suggesting a microbial origin. The observed differential fractionation of organics among hydroxy-Al mineral types suggests that microbial activity superimposed with abiotic mineral-surface-mediated fractionation leads to strong density differentiation of organo-mineral complex composition even over the short time scales probed in these incubation experiments. The data highlight the strong interdependency of mineral transformation, microbial community activity, and organic matter stabilization during biodegradation. Published by Elsevier Ltd.

TI A membrane inlet mass spectrometry system for noble gases at natural abundances in gas and water samples SO RAPID COMMUNICATIONS IN MASS SPECTROMETRY LA English DT Article ID ARTIFICIAL RECHARGE; SHALLOW GROUNDWATER; INJECTED HELIUM; EXCESS AIR; AQUIFER; TRACER; DENITRIFICATION; METHANE; PALEOTEMPERATURE; CONTAMINATION AB RATIONALENoble gases dissolved in groundwater can reveal paleotemperatures, recharge conditions, and precise travel times. The collection and analysis of noble gas samples are cumbersome, involving noble gas purification, cryogenic separation and static mass spectrometry. A quicker and more efficient sample analysis method is required for introduced tracer studies and laboratory experiments. METHODSA Noble Gas Membrane Inlet Mass Spectrometry (NG-MIMS) system was developed to measure noble gases at natural abundances in gas and water samples. The NG-MIMS system consists of a membrane inlet, a dry-ice water trap, a carbon-dioxide trap, two getters, a gate valve, a turbomolecular pump and a quadrupole mass spectrometer equipped with an electron multiplier. Noble gases isotopes He-4, Ne-22, Ar-38, Kr-84 and Xe-132 are measured every 10s. RESULTSThe NG-MIMS system can reproduce measurements made on a traditional noble gas mass spectrometer system with precisions of 2%, 8%, 1%, 1% and 3% for He, Ne, Ar, Kr and Xe, respectively. Noble gas concentrations measured in an artificial recharge pond were used to monitor an introduced xenon tracer and to reconstruct temperature variations to within 2 degrees C. Additional experiments demonstrated the capability to measure noble gases in gas and in water samples, in real time. CONCLUSIONSThe NG-MIMS system is capable of providing analyses sufficiently accurate and precise for introduced noble gas tracers at managed aquifer recharge facilities, groundwater fingerprinting based on excess air and noble gas recharge temperature, and field and laboratory studies investigating ebullition and diffusive exchange.

This publication will address the anomalies of phase evolution in the Al-Si-Fe hypoeutectic casting alloy system; the anomaly lies in the peculiarities in the evolution and nature of the intermetallic phases when compared to the thermodynamic phase diagram predictions and past publications of the same. The influence of the following parameters, in various combinations, on the evolution and nature of the intermetallic phases were analyzed and reported: concentration of Si between 2 and 12.6 wt%, Fe between 0.05 and 0.5 wt% and solidification rates of 0.1, 1, 5 and 50 K s(-1). Two intermetallic phases are observed to evolve in these alloys under these solidification conditions: the tau(5)-Al8SiFe2 and tau(6)-Al9Fe2Si2. The tau(5)-Al8SiFe2 phase evolves at all levels of the parameters during solidification and subsequently transforms into the tau(6)-Al9Fe2Si2 through a peritectic reaction when promoted by certain combinations of solidification parameters such as higher Fe level, lower Si level and slower solidification rates. Further, it is also hypothesized from experimental evidences that the theta-Al13Fe4 binary phase precludes the evolution of the tau(5) during solidification and subsequently transforms into the tau(6) phase during solidification. These observations are anomalous to the publications as prior art and simulation predictions of thermodynamic phase diagrams of these alloys, wherein, only one intermetallic phases in the tau(6)-Al9Fe2Si2 is predicted to evolve and be retained as the terminal phase at the end of solidification. Several analysis methods such as light optical microscope, scanning electron microscope equipped with a dual beam focused ion beam milling machine and energy dispersive X-ray diffraction system, transmission electron microscope equipped with high resolution digital imaging system, energy dispersive X-ray diffraction system, and high energy synchrotron beam source for nano-diffraction coupled with X-ray fluorescence imaging system was used in this study.

Yang, Tai-Ni He, Lilin TI Hydrogen trapping at dislocation cores at room temperature in deformed Pd SO JOURNAL OF ALLOYS AND COMPOUNDS LA English DT Article DE Hydrogen trapping; Dislocations; Palladium; SANS ID SINGLE-CRYSTAL PD; SANS MEASUREMENTS; DEUTERIUM; PALLADIUM AB Small-angle neutron scattering (SANS) measurements of hydrogen segregation at dislocations in heavily deformed single crystal Pd have been performed at very low solute concentration (PdH0.0016) at equilibrium with respect to hydrogen gas at 295 K. The net (the without-hydrogen measurement subtracted from with-hydrogen measurement) absolute differential macroscopic scattering cross section has been fit with a cylindrical form factor to represent the Cottrell atmosphere, yielding local trapped concentration delta similar to 0.06 [H]/[Pd], local volumetric dilatation f similar to 1.01, and trapping radius R 4 A of the segregated hydrogen. This measurement augments SANS results below ambient temperature [B.J. Heuser, H. Ju, Phys. Rev. B 83 (2011) 094103]. The temperature dependence of the measured radius is confirmed by a Fourier transform of hydrogen occupation at dislocations based on an elastic continuum treatment [Trinkle et al., Phys. Rev. B 83 (2011) 174116]. The measured trapping parameters are consistent with a depopulation of weak long-range dislocation strain fields at ambient temperature; hydrogen binding to stronger core dislocation sites persists at 295 K and results in the measured net scattering. The local solute concentration and trapping radius (less than two Burgers vectors in Pd), are both too small to support optic mode dispersion due to inter-hydrogen interactions. This result supports the conclusion that trapped hydrogen undergoes a hydride to solid solution phase transformation between 200 and 300 K based on hydrogen vibration density of states measurements using incoherent inelastic neutron scattering [Trinkle et al., Phys. Rev. B 83 (2011) 174116, Ju et al., Nucl. Instr. Meth. Phys. Res. A 654, (2011) 522, and Heuser et al., Phys. Rev. B 78 (2008) 214101]. (C) 2013 Elsevier B.V. All rights reserved.

First-order magnetostructural transition from paramagnetic hexagonal Ni2In-type parent phase to ferromagnetic orthorhombic TiNiSi-type martensite was achieved. A giant magnetocaloric effect of Delta S-m = -9.74J kg(-1) K-1 was obtained under magnetic field change of 5 T in the vicinity of phase transition temperature. This result indicates that Fe doped Mn-Co-Ge alloys are ideal candidates for magnetic refrigeration applications. Furthermore, the magnetic field-induced martensitic transformation, associated with a large lattice strain of similar to 12%, was directly evidenced by in situ synchrotron high-energy X-ray diffraction.

The time accuracy of the common solution approach is shown, both analytically and numerically, to be limited to first order due to operator splitting errors, low-order time integration of the remap terms, and other postulated first-order errors, even if the Lagrange step is second-order accurate in time. Additional numerical studies are used to demonstrate how these errors can be eliminated with an unsplit treatment that solves the remap terms directly. The Discontinuous Remap Method, in which a new mesh is generated during the remap step, also is shown to be first-order accurate in time. (C) 2013 Elsevier Inc. All rights reserved.

TI On particle movers in cylindrical geometry for Particle-In-Cell simulations SO JOURNAL OF COMPUTATIONAL PHYSICS LA English DT Article DE Equation of motion; Particle orbit integration; Boris' mover; Electromagnetic particle simulations; Strang operator splitting; Particle-In-Cell; Second order particle orbit integrator; Cyclotronic mover ID BEAM TRANSPORT; CODE AB Three movers for the orbit integration of charged particles in a given electromagnetic field are analyzed and compared in cylindrical geometry. The classic Boris mover, which is of leap-frog type with position and velocities staggered by half time step, is connected to a second order Strang operator splitting integrator. In general the Boris mover is about 20% faster than the Strang splitting mover without sacrificing much in terms of accuracy. Furthermore, the Boris mover is second order accurate only for a very specific choice of the initial half step needed by the algorithm to get started. Unlike the case in Cartesian geometry, where any initial half step which is at least first order accurate does not compromise the second order accuracy of the method, in cylindrical geometry any attempt to use a more accurate initial half step does in fact decrease the accuracy of the scheme to first order. Through the connection with the Strang operator splitting integrator, this counter-intuitive behavior is explained by the fact that the error in the half step velocities of the Boris mover is proportional to the time step of the simulation. For the case of a uniform and static magnetic field, we discuss the leap-frog cyclotronic mover, cylindrical analogue of the cyclotronic mover of Ref. [L. Patacchini and I. Hutchinson, J. Comput. Phys. 228 (7), 2009], where the step involving acceleration due to inertial forces is combined with the acceleration due to the magnetic part of the Lorentz force. The advantage of a cyclotronic mover is that the gyration of a charged particle in a magnetic field is treated analytically and therefore only the dynamics associated with the electric field needs to be resolved.

The dense Cu2O nanocoral electrode thermally transfers from Cu(OH)(2) nanowires by means of the dehydrate and deoxidization processes under nitrogen atmosphere. Mott-Schottky plot shows the flat-band potential of the coral-like Cu2O nanostructural film to be -0.1 V and a hole concentration of 8.2 x 10(19) cm(-3). Direct band gap of 2.08 eV in Cu2O film is determined via incident photon-to-electron conversion efficiency measurement. Significantly, this Cu2O nanocoral photocathode exhibits remarkable photocurrent of -1.3 mA cm(-2) at a potential of -0.6 V vs Ag/AgCl, corresponding to the solar conversion efficiency of 1.47%. These results demonstrate the great potential of Cu2O nanocoral film in solar hydrogen applications. Crown Copyright (C) 2013 Published by Elsevier B.V. All rights reserved.

Reversible operation of SOCs includes electricity generation in the fuel cell mode and hydrogen generation in the electrolysis mode. Degradation is a more significant issue when operating SOCs in the electrolysis mode. In order to understand and mitigate the degradation issues in high temperature electrolysis, single SOCs with different configurations from several manufacturers have been evaluated for initial performance and long-term durability. Cells were obtained from four industrial partners. Cells from Ceramatec Inc. and Materials and Systems Research Inc. (MSRI) showed improved durability in electrolysis mode compared to previous stack tests. Cells from Saint Gobain Advanced Materials Inc. (St. Gobain) and SOFCPower Inc. demonstrated stable performance in the fuel cell mode, but rapid degradation in the electrolysis mode, especially at high current density. Electrolyte electrode delamination was found to have a significant impact on degradation in some cases. Enhanced bonding between electrolyte and electrode and modification of the electrode microstructure helped to mitigate degradation. Polarization scans and AC impedance measurements were performed during the tests to characterize cell performance and degradation. (C) 2013 Elsevier B.V. All rights reserved.

The carbon left from the decomposition of polymers is an effective binder between the metal oxides and nickel foam. As compared to the metal oxide powder prepared in a conventional way by using polymer binder and carbon black, these one-step direct growth electrodes showed much better Li storage properties with high capacities, stable cyclability, and rate capability: Co3O4 on nickel foam gave a capacity of 900 mAh g(-1), at a current density of 1 A g(-1) and 600 mAh g(-1) at 4 A g(-1). The good performances of these electrodes could be attributed to intimate contact between the active material and nickel foam, the porosity of the current collector, and the network structure of the active materials. This general method could also be applied to other transition metal oxides. (C) 2013 Elsevier B.V. All rights reserved.

This paper tries to put effort on estimating the SoC of cells series lithium-ion battery pack for electric vehicles with adaptive data-driven based SoC estimator. First, a lumped parameter equivalent circuit model is developed. Second, to avoid the drawbacks of cell-to-cell variations in battery pack, a filtering approach for ensuring the performance of capacity/resistance conformity in battery pack has been proposed. The multi-cells "pack model" can be simplified by the unit model. Third, the adaptive extended Kalman filter algorithm has been used to achieve accurate SoC estimates for battery packs. Last, to analyze the robustness and the reliability of the proposed approach for cells and battery pack, the federal urban driving schedule and dynamic stress test have been conducted respectively. The results indicate that the proposed approach not only ensures higher voltage and SoC estimation accuracy for cells, but also achieves desirable prediction precision for battery pack, both the pack's voltage and SoC estimation error are less than 2%.

The uniform distribution of PEDOT-NWs with 60-80 nm in diameter and several microns in length, and their-characteristics of infrared absorption are determined by SEM and FTIR, respectively. The electrochemical impedance analysis is performed to probe the diffusion characteristics of PEDOT-NWs/CC electrode. Moreover, high gravimetric capacitance of 256.1 F g(-1) at a specific energy of 182.1 Wh kg(-1) and a specific power of 13.1 kW kg(-1) is obtained under a wide operated potential of 1.6 V.

Its stability and compressional behavior were investigated using in-situ high-pressure synchrotron X-ray diffraction (XRD) at room temperature. No phase transition was observed in polycrystalline Li15Si4 up to 5.8 GPa. A bulk modulus of 28.4(6) GPa was obtained for Li15Si4 by fitting the XRD data to a third order Birch-Murnaghan equation of state. We found that the bulk modulus of Li15Si4 follows a linear interpolation relationship between the bulk moduli for pure Li and Si. These results provide valuable experimental data to validate the theoretical calculation and are also important inputs for modeling the Li-Si system. (C) 2013 Elsevier B.V. All rights reserved.

The intercalation compounds used in LIBs electrochemically react with Li+ ions via single or multiple phase transitions depending on the nature of the material structure as well as the synthesis and operating conditions. For LiNi0.5Mn1.5O4 high voltage spinel, a promising candidate positive electrode material for LIBs, there are three spinel-structured phases sequentially appeared through two successive two-phase reactions during the delithiation/lithiation processes. Here we demonstrate, experimentally and theoretically, that through elemental substitution, the solid solution ranges for both the first and second phases are significantly extended during the electrochemical charge-discharge process. This type of structural changes with more solid solution regions facilitate fast Li+ diffusion by reducing the number of phase boundaries that Li+ ions have to overcome and resulted in less shrinkage of the unit cells at the end of charge process. This work unravels the fundamental interactions between structural and electrochemical properties by using spinel as the platform, which may be widely adopted to explain or tailor the properties of materials for energy storage and conversion.

TI Configuring a fuel cell based residential combined heat and power system SO JOURNAL OF POWER SOURCES LA English DT Article DE Fuel cell; Polymer electrolyte; Heat and power; CHP; Systems analysis ID CHP; HYDROGEN; PEMFC AB The design and performance of a fuel cell based residential combined heat and power (CHP) system operating on natural gas has been analyzed. The natural gas is first converted to a hydrogen-rich reformate in a steam reformer based fuel processor, and the hydrogen is then electrochemically oxidized in a low temperature polymer electrolyte fuel cell to generate electric power. The heat generated in the fuel cell and the available heat in the exhaust gas is recovered to meet residential needs for hot water and space heating. Two fuel processor configurations have been studied. One of the configurations was explored to quantify the effects of design and operating parameters, which include pressure, temperature, and steam-to-carbon ratio in the fuel processor, and fuel utilization in the fuel cell. The second configuration applied the lessons from the study of the first configuration to increase the CHP efficiency. Results from the two configurations allow a quantitative comparison of the design alternatives. The analyses showed that these systems can operate at electrical efficiencies of similar to 46% and combined heat and power efficiencies of similar to 90%. (C) 2013 Elsevier B.V. All rights reserved.

TI A laboratory-scale pretreatment and hydrolysis assay for determination of reactivity in cellulosic biomass feedstocks SO BIOTECHNOLOGY FOR BIOFUELS LA English DT Article ID CHEMICAL-COMPOSITION; CORN STOVER; LIGNOCELLULOSIC BIOMASS; ENZYMATIC-HYDROLYSIS; ACID PRETREATMENT; ADVANCED BIOFUELS; DIGESTIBILITY; TECHNOLOGIES; SWITCHGRASS; MISCANTHUS AB Background: The rapid determination of the release of structural sugars from biomass feedstocks is an important enabling technology for the development of cellulosic biofuels. An assay that is used to determine sugar release for large numbers of samples must be robust, rapid, and easy to perform, and must use modest amounts of the samples to be tested. In this work we present a laboratory-scale combined pretreatment and saccharification assay that can be used as a biomass feedstock screening tool. The assay uses a commercially available automated solvent extraction system for pretreatment followed by a small-scale enzymatic hydrolysis step. The assay allows multiple samples to be screened simultaneously, and uses only similar to 3 g of biomass per sample. If the composition of the biomass sample is known, the results of the assay can be expressed as reactivity (fraction of structural carbohydrate present in the biomass sample released as monomeric sugars). Results: We first present pretreatment and enzymatic hydrolysis experiments on a set of representative biomass feedstock samples (corn stover, poplar, sorghum, switchgrass) in order to put the assay in context, and then show the results of the assay applied to approximately 150 different feedstock samples covering 5 different materials. From the compositional analysis data we identify a positive correlation between lignin and structural carbohydrates, and from the reactivity data we identify a negative correlation between both carbohydrate and lignin content and total reactivity. The negative correlation between lignin content and total reactivity suggests that lignin may interfere with sugar release, or that more mature samples (with higher structural sugars) may have more recalcitrant lignin. Conclusions: The assay presented in this work provides a robust and straightforward method to measure the sugar release after pretreatment and saccharification that can be used as a biomass feedstock screening tool. We demonstrated the utility of the assay by identifying correlations between feedstock composition and reactivity in a population of 150 samples.

Laser processing resulted in a finer scale of crystallites due to rapid heating and cooling during laser annealing compared to conventional furnace annealing process. A significant increase in saturation magnetization is observed for laser-annealed ribbons compared to both as-received and furnace annealed samples coupled with an increase in coercivity compared to the as received samples. The combined effect of thermal histories and stresses developed during laser annealing results in the formation of nano-crystalline phase along the laser track. The phase evolution is studied by micro-XRD and TEM analysis. Solute partitioning and compositional variation within the phases are obtained by Local Electrode Atom probe analysis. The evolution of microstructure is rationalized using a Finite Element based heat transfer multi-physics model. (C) 2013 AIP Publishing LLC.

It was observed that even relatively low concentrations of glycerol increase the damping of shear modes, as a consequence of the known ability of glycerol to disrupt the hydrogen bond network of water. A similar trend was observed when increasing the temperature, which suggests the presence of a locus in the concentration-temperature plane marking a crossover in the shear modulus.

Space, Brian TI Efficient calculation of many-body induced electrostatics in molecular systems SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID DIPOLE INTERACTION-MODEL; METAL-ORGANIC FRAMEWORK; POLARIZABLE FORCE-FIELD; EWALD SUMMATION; ATOM POLARIZABILITIES; SIMULATION; MECHANICS; CHEMISTRY; PROTEINS; DYNAMICS AB Potential energy functions including many-body polarization are in widespread use in simulations of aqueous and biological systems, metal-organics, molecular clusters, and other systems where electronically induced redistribution of charge among local atomic sites is of importance. The polarization interactions, treated here via the methods of Thole and Applequist, while long-ranged, can be computed for moderate-sized periodic systems with extremely high accuracy by extending Ewald summation to the induced fields as demonstrated by Nymand, Sala, and others. These full Ewald polarization calculations, however, are expensive and often limited to very small systems, particularly in Monte Carlo simulations, which may require energy evaluation over several hundred-thousand configurations. For such situations, it shall be shown that sufficiently accurate computation of the polarization energy can be produced in a fraction of the central processing unit (CPU) time by neglecting the long-range extension to the induced fields while applying the long-range treatments of Ewald or Wolf to the static fields; these methods, denoted Ewald E-Static and Wolf E-Static (WES), respectively, provide an effective means to obtain polarization energies for intermediate and large systems including those with several thousand polarizable sites in a fraction of the CPU time. Furthermore, we shall demonstrate a means to optimize the damping for WES calculations via extrapolation from smaller trial systems. (C) 2013 AIP Publishing LLC.

CA Belle Collaboration TI Evidence for the suppressed decay B- -> DK-, D -> K+ pi(-)pi(0) SO PHYSICAL REVIEW D LA English DT Article ID CP-VIOLATION; BELLE AB We report a study of the suppressed decay B- -> DK-, D -> K+ pi(-) pi(0), where D denotes either a D-0 or a (D) over bar (0) meson. The decay is sensitive to the CP-violating parameter phi(3). Using a data sample of 772 x 10(6) B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector, we measure the ratio of branching fractions of the above suppressed decay to the favored decay B- -> DK-, D -> K- pi(+) pi(0). Our result is R-DK = [1.98 +/- 0.62 (stat) +/- 0.24 (syst)] x 10(-2), which indicates the first evidence of the signal for this suppressed decay with a significance of 3.2 standard deviations. We measure the direct CP asymmetry between the suppressed B- and B+ decays to be A(DK) = 0.41 +/- 0.30(stat) +/- 0.05(syst). We also report measurements for the analogous quantities R-D pi and A(D pi) for the decay B- -> D pi(-), D -> K+ pi(-)pi(0).

CA CDF Collaboration TI Direct Measurement of the Total Decay Width of the Top Quark SO PHYSICAL REVIEW LETTERS LA English DT Article AB We present a measurement of the total decay width of the top quark using events with top-antitop quark pair candidates reconstructed in the final state with one charged lepton and four or more hadronic jets. We use the full Tevatron run II data set of root s = 1.96 TeV proton-antiproton collisions recorded by the CDF II detector. The top quark mass and the mass of the hadronically decaying W boson are reconstructed for each event and compared with distributions derived from simulated signal and background samples to extract the top quark width (Gamma(top)) and the energy scale of the calorimeter jets with in situ calibration. For a top quark mass M-top = 172.5 GeV/c(2), we find 1.10 < Gamma(top) < 4.05 GeV at 68% confidence level, which is in agreement with the standard model expectation of 1.3 GeV and is the most precise direct measurement of the top quark width to date.

Therefore, plane-wave density functional theory (DFT) calculations were performed to simulate water and carbon dioxide adsorption at the (010) surface of five olivine minerals, namely, forsterite (Mg2SiO4), calcio-olivine (Ca2SiO4), tephroite (Mn2SiO4), fayalite (Fe2SiO4), and Co-olivine (Co2SiO4). Adsorption energies per water molecule obtained from energy minimizations varied from -100 kJ mol(-1) for tephroite to -148 kJ mol(-1) for calcio-olivine at sub-monolayer coverage and became less exothermic as coverage increased. In contrast, carbon dioxide adsorption energies at sub-monolayer coverage ranged from -44 kJ mol(-1) for fayalite to -83 kJ mol(-1) for calcio-olivine. Therefore, the DFT calculations show a strong driving force for carbon dioxide displacement by water at the surface of all olivine minerals in a competitive adsorption scenario. Additionally, adsorption energies for both water and carbon dioxide were found to be more exothermic for the alkaline-earth (AE) olivines than for the transition-metal (TM) olivines and to not correlate with the solvation enthalpies of the corresponding divalent cations. However, a correlation was obtained with the charge of the surface divalent cation indicating that the more ionic character of the AE cations in the olivine structure relative to the TM cations leads to greater interactions with adsorbed water and carbon dioxide molecules at the surface and thus more exothermic adsorption energies for the AE olivines. For calcio-olivine, which exhibits the highest divalent cation charge of the five olivines, ab initio molecular dynamics simulations showed that this effect leads both water and carbon dioxide to react with the surface and form hydroxyl groups and a carbonate-like species, respectively.

TI Evaluation of experimentally measured and model-calculated pH for rock-brine-CO2 systems under geologic CO2 sequestration conditions SO CHEMICAL GEOLOGY LA English DT Article DE Carbon dioxide; Sequestration; pH; In-situ; Geochemical modeling; Rock-brine-CO2 interaction ID DEEP SALINE AQUIFERS; IN-SITU; CARBON-DIOXIDE; ATR-FTIR; DISSOLUTION; STORAGE; PRECIPITATION; PRESSURE; REACTIVITY; SANDSTONE AB Reliable pH estimation is essential for understanding the geochemical reactions that occur in rock-brine-CO2 systems when CO2 is injected into deep geologic formations for long-term storage. Due to a lack of reliable experimental methods, most laboratory studies of CO2-rock-brine interactions conducted under geologic CO2 sequestration (GCS) conditions have relied on thermodynamic modeling to estimate pH; however, the accuracy of these model predictions is typically uncertain. In this study, we expanded the measurement range of a spectrophotometric method for pH determination, and we applied the method to measure the pH in batch-reactor experiments at 75 degrees C and 100 atm utilizing rock samples from five ongoing GCS demonstration projects. A combination of color-changing pH indicators, bromophenol blue and bromocresol green, was shown to enable measurements over the pH range of 2.5-5.2. In-situ pH measurements were compared with pH values calculated using geochemical models. Calculations with four different thermodynamic databases resulted in a maximum difference of 0.16 pH units. Among these databases, the Phrqpitz database generally provided the most accurate pH predictions for rocks comprised of carbonate, siltstone, and sandstone. With Phrqpitz, the differences between measured and calculated pH values were within 0.03 pH units for these three rocks. However, for basalt, significant differences (0.10-0.25 pH units) were observed even with Phrqpitz. These discrepancies may be due to the models' failure to fully account for certain proton consuming and producing reactions that occur between the basalt minerals and CO2-saturated brine solutions.

FePP-ImCO was shown to lose the CO ligand upon excitation at the Q bands, with 3.8 ps vibrational cooling and 21.6 ps intersystem crossing time constants derived from optical TA experiments, followed by ligation of a second Im on the nanosecond time scale. The penta-coordinate FePP-Im intermediate which forms following CO dissociation adopts a square pyramidal geometry with a "domed" iron center that is reminiscent of that formed upon loss of CO from carbonmonoxymyoglobin (MbCO). Unlike MbCO, which typically retains its newly generated penta-coordinated geometry until CO recombination, FePP can adopt a hexa-coordinate geometry by binding an additional Im ligand (FePP (Im)2), allowing the porphyrin to exist in the low-spin electronic state even without the CO attached. The second Im ligand remains bound until CO recombination occurs with a time constant of 283 its. The photodissociated states of FePP-ImCO and MbCO 100 ps after photoexcitation have similar iron site geometries, implying that the protein matrix in MbCO maintains minimum potential energy in the heme center despite the large-scale reorganization in the protein secondary and tertiary structure that arises from the dynamic active site/matrix interaction.

TI Modeling Water Adsorption on Rutile (110) Using van der Waals Density Functional and DFT plus U Methods SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID INITIO MOLECULAR-DYNAMICS; TOTAL-ENERGY CALCULATIONS; AUGMENTED-WAVE METHOD; BASIS-SET; TIO2(110); TIO2; 1ST-PRINCIPLES; TRANSITION; STABILITY; SURFACE AB We study the energetics and structure of water absorption on the ideal rutile TiO2 (110) surface using dispersion-corrected periodic density functional theory (DFT) calculations and on-site Coulomb potential (DFT+U) corrections. Conventional (PBE) and self-consistent dispersion-corrected DFT methods (vdw-DF1 and vdw-DF2) both suggest that molecular adsorption of intact water molecules on the rutile (110) surface is increasingly preferred with increasing simulation slab thickness. However, empirical dispersion corrections indicate a mix of molecular and dissociated water may coexist at room temperature, with less dependence on slab thickness. This same behavior is seen for DFT+U with U = 3 eV in combination with or without self-consistent dispersion corrected DFT. We find that the preference for the occurrence of dissociated water increases with increasing U. When compared with experimental bond-length data for the adsorbed water species, none of the methods and slab thicknesses correctly predict all bond lengths simultaneously. However, of the methods that energetically favor coexisting associated and dissociated water species on the surface, the three-layer slab with conventional DFT (PBE) and the empirically dispersion-corrected DFT methods come closest to correctly reproducing all of the experimentally observed bond lengths. We conclude that the current level of DFT is insufficient to definitively distinguish between the fully associated and partially dissociated states of water adsorbed on the pristine rutile (110) surface, due to the very small (similar to 0.1 eV) total energy differences between these states.

In situ specular crystal truncation rod and resonant anomalous X-ray reflectivity data show that Y3+ adsorbs as three distinct species (inner-sphere, adsorbed outer-sphere, and extended outer-sphere) among which the fractional coverage of the inner-sphere species (similar to 10%) is the smallest. Uptake measurements show that the maximum Y3+ coverage is higher by 50% than the amount needed to satisfy the muscovite surface charge in the absence of background electrolyte, but this overcharging is largely suppressed in the presence of 0.1 m NaCl. The measured intrinsic standard-state Gibbs free energy for Y3+ adsorption (-36.9 +/- 0.9 kJ/mol) is smaller than that expected solely on the basis of its charge, and this discrepancy can be partly explained by the difference in adsorbed cation speciation at the charged interface.

SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID SOLID-ELECTROLYTE INTERPHASE; ALKALI BORATE GLASSES; LITHIUM BIS(OXALATO)BORATE; CELLS; CENTERS; ESR; ADDITIVES; RESONANCE; CORROSION; BASICITY AB Lithium bis(oxalato)borate (LiBOB) and lithium difluoro(oxalato)borate (LiDFOB) are uniquely efficient as electrolyte additives in carbonate-based Li-ion batteries. Electrochemical redox reactions of these anions facilitate the formation of robust solid-electrolyte interphases (SEIs) at the graphite and oxide electrodes. We used electron paramagnetic resonance (EPR) spectroscopy to demonstrate that oxidation of these anions causes the elimination of a carbon dioxide molecule and the formation of a stable acyl radical, whereas the reduction of these anions results in the loss of oxalate (for BOB) or fluoride anions (for DFOB) and the concurrent formation of oxalatoboryl adducts. The latter species enters a previously identified radical cycle implicated in SEI formation. Recombination of the acyl radicals at the oxide-electrolyte interface yields difluoroborane dimers that (being strong Lewis acids) form strong B-O bonds with oxygens at the surface, thereby passivating the electrode and preventing oxidation of the electrolyte.

TI Thin Film Approach to Single Crystalline Electrochemistry SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID SCANNING-TUNNELING-MICROSCOPY; OXYGEN REDUCTION REACTION; SULFURIC-ACID-SOLUTION; IN-SITU STM; AU(111) ELECTRODE; INFRARED-SPECTROSCOPY; HYDROGEN ADSORPTION; SURFACE-MORPHOLOGY; PT(111) ELECTRODES; OXIDE FORMATION AB Implementation of single-crystal metal electrodes into standard electrochemical procedures has provided invaluable insight into the structure of and processes occurring at the metal-electrolyte interface. However, the accuracy required in their manufacture to provide ideally cut crystals with the lowest possible degree of miscut in conjunction with the amount of material required, especially in the case of precious metals, can make their use highly restrictive. We present here fundamental insight into a general procedure for producing thin metal films containing large, atomically flat (111) terraces without the use of an epitaxial template. Thermal annealing in a controlled atmosphere induces long-range ordering in magnetron sputtered thin metal films deposited on an amorphous substrate. The ordering transition in these thin metal films yields characteristic (111) electrochemical signatures with minimal amount of material and provides an adequate replacement for oriented bulk single crystals. Moreover, this approach can be generalized and applied toward development of a new class of thin-film-based catalysts.

TI Comparison of the Photodesorption Activities of cis-Butene, trans-Butene, and Isobutene on the Rutile TiO2(110) Surface SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID PHOTOELECTRON-SPECTRA; TIO2; CATALYSTS; OLIGOMERIZATION; PHOTOCHEMISTRY; PHOTOOXIDATION; TRIMERIZATION; MOLECULES; CHEMISTRY; ENERGIES AB The photodesorption properties of three butene molecules (cis-butene, trans-butene, and isobutene) were explored on the clean rutile TiO2(110) surface using temperature programmed desorption (TPD) and photon simulated desorption (PSD). At the low coverage limit, trans-butene is the most strongly bound butene on the TiO2(110) surface, desorbing at 210 K. Steric repulsions between neighboring molecules diminishes the binding of trans-butene at higher coverage. Both cis-butene and isobutene saturate the first layer on TiO2(110) at a coverage of similar to 0.50 ML in a single TPD feature at 184 and 192 K, respectively. In contrast, the maximum coverage that trans-butene achieves in its 210 K peak is similar to 1/3 ML, with higher coverages desorbing at similar to 137 K. Coverages of these molecules above 0.50 ML populate second layer and multilayer states. The instability of trans-butene at a coverage of 0.5 ML on the surface is linked to the inversion center in its symmetry. The primary photochemical pathway of each butene molecule on the clean TiO2(110) surface is photodesorption. The photodesorption activities of these molecules on TiO2(110) at an initial coverage of 0.50 ML follows the trend: isobutene >= cis-butene > trans-butene. In contrast, the photodesorption activities at low initial coverage exceeds that measured at 0.50 ML, suggesting coverage-dependent effects on the photodesorption rate. The low photodesorption activity of trans-butene at a coverage of 0.50 ML may be linked to a weakened interaction between the molecule's C=C pi bond and the surface Ti4+ adsorption site due to steric repulsions between neighboring molecules. These data suggest that steric repulsions may play a significant role in diminishing the photoactivities of weakly bound molecules on TiO2 photocatalysts.

The goal was to address the link between the corrugation-driven hydration free energy changes in the association process involving graphene plates and the resulting water-graphene interfacial tension, to interrogate the effect of the surface corrugation and confinement on the thermodynamic response functions and the dynamics of confined water and to put the observed behavior in the context of Wenzel's modification of Young's equation. We found that graphene confinement induces a significant increase in the isothermal compressibility and isobaric thermal expansivity as well as a pronounced slowdown of the dynamics of water over that of the corresponding bulk counterpart, whose magnitudes depend on the type of surface corrugation involved. Our simulation results for different types of corrugated graphene plates involving identical surface areas do not support the meaning of the "r"-factor underlying Wenzel's equation for corrugated nanoscale surfaces.

The formation of two phases, predicted from bulk thermodynamics, has been suppressed in all compositions. Instead, a single phase solid solution forms after heat treatment at 600 degrees C and slow cooling. However, bulk phase relationships, signified by the precipitation of alpha-Fe upon cooling, was observed in larger particles (>20 nm) with composition Fe-35 at. % Au. The suppression of the phase transformation/precipitation in small particles is explained thermodynamically, as the free energy decrease associated with the phase transformation does not exceed the increase in energy due to the introduction of an interphase interface (grain boundary) within the cluster. A general equation has been derived to predict the critical cluster size below which transformations are inhibited, which agrees well with the observed experimental results.

TI Coupled-cluster studies of infinite nuclear matter SO PHYSICAL REVIEW C LA English DT Article ID SHORT-RANGE CORRELATIONS; STRONGLY INTERACTING PARTICLES; MANY-BODY PROBLEM; V14 POTENTIALS; ELECTRON-GAS; EXPANSION; MODEL; STATE; RING; SUMMATION AB Background: Coupled-cluster (CC) theory is a widely used many-body method for studying strongly correlated many-fermion systems. It allows for systematic inclusions of complicated many-body correlations beyond a mean field. Recent applications to finite nuclei have shown that first-principles approaches like CC theory can be extended to studies of medium-heavy nuclei, with excellent agreement with experiment. However, CC calculations of properties of infinite nuclear matter are rather few and date back more than 30 yr. Purpose: The aim of this work is thus to develop the relevant formalism for performing CC calculations in nuclear matter and neutron-star matter, including thereby important correlations to infinite order in the interaction and testing modern nuclear forces based on chiral effective field theory. Our formalism includes also the exact treatment of the so-called Pauli operator in a partial-wave expansion of the equation of state. Methods: Nuclear-and neutron-matter calculations are done using a coupled particle-particle and hole-hole ladder approximation. The coupled ladder equations are derived as an approximation of CC theory, leaving out particle-hole and nonlinear diagrams from the CC doubles amplitude equation. This study is a first step toward CC calculations for nuclear and neutron matter. Results: We present results for both symmetric nuclear matter and pure neutron matter employing state-of-the-art nucleon-nucleon interactions based on chiral effective field theory. We employ also the newly optimized chiral interaction [Ekstrom et al., Phys. Rev. Lett. 110, 192502 (2013)] to study infinite nuclear matter. The ladder approximation method and corresponding results are compared with conventional Brueckner-Hartree-Fock theory. The ladder approximation is derived and studied using both exact and angular-averaged Pauli exclusion operators, with angular-averaged input momenta for the single-particle potentials in all calculations. The inclusion of an exact treatment of the Pauli operators in a partial-wave expansion yields corrections of the order of 1.7%-2% of the total energy in symmetric nuclear matter. Similarly, the inclusion of both hole-hole and particle-particle ladders result in corrections of the order 0.7%-2% compared to the approximation with only particle-particle ladders. Including these effects, we get at most almost a 6% difference between our CC calculation and the standard Brueckner-Hartree-Fock approach. Conclusions: We have performed CC calculations of symmetric nuclear matter and pure neutron matter including particle-particle and hole-hole diagrams to infinite order using an exact Pauli operator and angular-averaged single-particle energies. The contributions from hole-hole diagrams and exact Pauli operators add important changes to the final energies per particle.

Recent work has shown that the relative velocity effect may have a dramatic impact on the star formation at high redshifts, if first stars are formed in minihalos around z similar to 20, or if the effect propagates through secondary effects to stars formed at later redshifts. The relative velocity effect has particularly strong signatures in the large scale clustering of these sources, including the baryonic acoustic oscillation position. Assuming that a small fraction of stars in low-redshift massive galaxies retain the memory of the primordial relative velocity effect, galaxy clustering measurements can be used to constrain the signatures of the first stars. Luminous red galaxies contain some of the oldest stars in the Universe and are ideally suited to search for this effect. Using the BOSS power spectrum measurements from the Sloan Data Release 9, in combination with Planck, we derive the upper limit on the fraction of the stars sensitive to the relative velocity effect f(star) < 3.3% at the 95% confidence level in the CMASS galaxy sample. If an additional galaxy sample not sensitive to the effect is available in a given survey, a joint multitracer analysis can be applied to construct a samplevariance canceling combination, providing a model-independent way to verify the presence of the relative velocity effect in the galaxy power spectrum on large scales. Such a multitracer analysis in future galaxy surveys can greatly improve the current constraint, achieving a 0.1% level in f(star).

TI Improved Activity of a Thermophilic Cellulase, Cel5A, from Thermotoga maritima on Ionic Liquid Pretreated Switchgrass SO PLOS ONE LA English DT Article ID CORN STOVER; ENZYMATIC-HYDROLYSIS; ENDOGLUCANASE CEL5A; DIRECTED EVOLUTION; RANDOM MUTAGENESIS; BIOMASS; BIOFUELS; OPTIMIZATION; CHEMICALS; CATALYSIS AB Ionic liquid pretreatment of biomass has been shown to greatly reduce the recalcitrance of lignocellulosic biomass, resulting in improved sugar yields after enzymatic saccharification. However, even under these improved saccharification conditions the cost of enzymes still represents a significant proportion of the total cost of producing sugars and ultimately fuels from lignocellulosic biomass. Much of the high cost of enzymes is due to the low catalytic efficiency and stability of lignocellulolytic enzymes, especially cellulases, under conditions that include high temperatures and the presence of residual pretreatment chemicals, such as acids, organic solvents, bases, or ionic liquids. Improving the efficiency of the saccharification process on ionic liquid pretreated biomass will facilitate reduced enzyme loading and cost. Thermophilic cellulases have been shown to be stable and active in ionic liquids but their activity is typically at lower levels. Cel5A_Tma, a thermophilic endoglucanase from Thermotoga maritima, is highly active on cellulosic substrates and is stable in ionic liquid environments. Here, our motivation was to engineer mutants of Cel5A_Tma with higher activity on 1-ethyl-3-methylimidazolium acetate ([C(2)mim][OAc]) pretreated biomass. We developed a robotic platform to screen a random mutagenesis library of Cel5A_Tma. Twelve mutants with 25-42% improvement in specific activity on carboxymethyl cellulose and up to 30% improvement on ionic-liquid pretreated switchgrass were successfully isolated and characterized from a library of twenty thousand variants. Interestingly, most of the mutations in the improved variants are located distally to the active site on the protein surface and are not directly involved with substrate binding.

TI A 500-kiloton airburst over Chelyabinsk and an enhanced hazard from small impactors SO NATURE LA English DT Article ID EARTH; ASTEROIDS; INFRASOUND; EXPLOSION; COMETS AB Most large (over a kilometre in diameter) near-Earth asteroids are now known, but recognition that airbursts (or fireballs resulting from nuclear-weapon-sized detonations of meteoroids in the atmosphere) have the potential to do greater damage(1) than previously thought has shifted an increasing portion of the residual impact risk (the risk of impact from an unknown object) to smaller objects(2). Above the threshold size of impactor at which the atmosphere absorbs sufficient energy to prevent a ground impact, most of the damage is thought to be caused by the airburst shock wave(3), but owing to lack of observations this is uncertain(4,5). Here we report an analysis of the damage from the airburst of an asteroid about 19 metres (17 to 20 metres) in diameter southeast of Chelyabinsk, Russia, on 15 February 2013, estimated to have an energy equivalent of approximately 500 (+/- 100) kilotons of trinitrotoluene (TNT, where 1 kiloton of TNT = 4.185x10(12) joules). We show that a widely referenced technique(4-6) of estimating airburst damage does not reproduce the observations, and that the mathematical relations(7) based on the effects of nuclear weapons-almost always used with this technique-overestimate blast damage. This suggests that earlier damage estimates(5,6) near the threshold impactor size are too high. We performed a global survey of airbursts of a kiloton or more (including Chelyabinsk), and find that the number of impactors with diameters of tens of metres may be an order of magnitude higher than estimates based on other techniques(8,9). This suggests a non-equilibrium(if the population were in a long-term collisional steady state the size-frequency distribution would either follow a single power law or there must be a size-dependent bias in other surveys) in the near-Earth asteroid population for objects 10 to 50 metres in diameter, and shifts more of the residual impact risk to these sizes.

We employ the time-dependent close-coupling method based on an expansion of a one-electron three dimensional wavefunction, for the single ionization, and an expansion of a two-electron six dimensional wavefunction, for the single and double ionization processes. The results are compared with experimental data and very good agreement is achieved. For this particular highly charged and swift projectile we include monopole, dipole, quadrupole, octopole and hexadecapoles for the projectile-atom interaction and we have made additional tests adding up superior multipole terms (triakontadipole and beyond). In order to obtain single differential cross sections for double ionization that are in very good agreement with experimental data, over 100 coupled channels are needed. C1 [Ciappina, M.

TI The epsomitic phototrophic microbial mat of Hot Lake, Washington: community structural responses to seasonal cycling SO FRONTIERS IN MICROBIOLOGY LA English DT Article DE Hot Lake; phototrophic microbial mats; 16S tag sequencing; phylogenetic turnover; microbial diversity; seasonal cycling; community assembly; magnesium sulfate ID CYANOBACTERIAL MAT; BRITISH-COLUMBIA; MAXIMUM-LIKELIHOOD; ASSEMBLY PROCESSES; SALINITY GRADIENT; CARIBOO PLATEAU; DIVERSITY; LIGHT; PHOTOSYNTHESIS; TEMPERATURE AB Phototrophic microbial mats are compact ecosystems composed of highly interactive organisms in which energy and element cycling take place over millimeter-to-centimeter-scale distances. Although microbial mats are common in hypersaline environments, they have not been extensively characterized in systems dominated by divalent ions. Hot Lake is a meromictic, epsomitic lake that occupies a small, endorheic basin in north-central Washington. The lake harbors a benthic, phototrophic mat that assembles each spring, disassembles each fall, and is subject to greater than tenfold variation in salinity (primarily Mg2+ and SO42-) and irradiation over the annual cycle. We examined spatiotemporal variation in the mat community at five time points throughout the annual cycle with respect to prevailing physicochemical parameters by amplicon sequencing of the V4 region of the 16S rRNA gene coupled to near-full-length 16S RNA clone sequences. The composition of these microbial communities was relatively stable over the seasonal cycle and included dominant populations of Cyanobacteria, primarily a group IV cyanobacterium (Leptolyngbya), and Alphaproteobacteria (specifically, members of Rhodobacteraceae and Geminicoccus). Members of Gammaproteobacteria (e.g., Thioalkalivibrio and Halochromatium) and Deltaproteobacteria (e.g., Desulfofustis) that are likely to be involved in sulfur cycling peaked in summer and declined significantly by mid-fall, mirroring larger trends in mat community richness and evenness. Phylogenetic turnover analysis of abundant phylotypes employing environmental metadata suggests that seasonal shifts in light variability exert a dominant influence on the composition of Hot Lake microbial mat communities. The seasonal development and organization of these structured microbial mats provide opportunities for analysis of the temporal and physical dynamics that feed back to community function.

While this microbial host has great potential to be engineered to produce desired compounds (beyond polyhydroxybutyrate) directly from CO2, little work has been done to develop genetic part libraries to enable such endeavors. Results: We report the development of a toolbox for the metabolic engineering of Ralstonia eutropha H16. We have constructed a set of broad-host-range plasmids bearing a variety of origins of replication, promoters, 5' mRNA stem-loop structures, and ribosomal binding sites. Specifically, we analyzed the origins of replication pCM62 (IncP), pBBR1, pKT (IncQ), and their variants. We tested the promoters P-BAD, T7, P-xyls/PM, P-lacUV5, and variants thereof for inducible expression. We also evaluated a T7 mRNA stem-loop structure sequence and compared a set of ribosomal binding site (RBS) sequences derived from Escherichia coli, R. eutropha, and a computational RBS design tool. Finally, we employed the toolbox to optimize hydrocarbon production in R. eutropha and demonstrated a 6-fold titer improvement using the appropriate combination of parts. Conclusion: We constructed and evaluated a versatile synthetic biology toolbox for Ralstonia eutropha metabolic engineering that could apply to other microbial hosts as well.

Following a design principle that suggests using d5(5) cations for good p-type conductivity in oxides, the Inverse Design approach is applied to the class of ternary Mn(II) oxides, which are usually considered to be insulating materials. As a result, Cr2MnO4 is identified as an oxide closely following selection metrics of thermodynamic stability, wide-gap, p-type dopability, and band-conduction mechanism for holes (no hole self-trapping). Lacking an intrinsic hole-producing acceptor defect, Li is further identified as a suitable dopant. Bulk synthesis of Li-doped Cr2MnO4 exhibits at least five orders of magnitude enhancement of the hole conductivity compared to undoped samples. This novel approach of stating functionality first, then theoretically searching for candidates that merits synthesis and characterization, promises to replace the more traditional non-systematic approach for the discovery of advanced functional materials.

It has a 4200 mAh/g theoretical capacity, which is ten times higher than that of commercial graphite anodes. However, when lithium ions diffuse to Si anodes, the volume of Si will expand to almost 400% of its initial size and lead to the crack of Si. Such a huge volume change and crack cause significant capacity loss. Meanwhile, with the crack of Si particles, the conductivity between the electrode and the current collector drops. Moreover, the solid electrolyte interphase (SEI), which is generated during the cycling, reduces the discharge capacity. These issues must be addressed for widespread application of this material. In this work, caramel popcorn shaped porous silicon particles with carbon coating are fabricated by a set of simple chemical methods as active 'anode material. Si particles are 'etched to form a porous structure. The pores in Si provide space for the volume expansion and liquid electrolyte diffusion. A layer of amorphous carbon is formed inside the pores, which gives an excellent isolation between the Si particle and electrolyte, so that the formation of the SEI layer is stabilized. Meanwhile, this novel structure enhances the mechanical properties of the Si particles, and the crack phenomenon caused by the volume change is significantly restrained. Therefore, an excellent cycle life under a high rate for the novel Si electrode is achieved. C1 [He, Meinan; Sa, Qina; Wang, Yan] Worcester Polytech Inst, Worcester, MA 01609 USA.

Li(Ni1-xMnx)O-2 (0.1 <= x <= 0.5) have been synthesized by a coprecipitation method. Rietveld refinement of X-ray diffraction and microscopic studies reveal dense and spherical secondary particles of highly crystalline phase with low cation mixing over the whole compositions, implying successful optimization of synthetic conditions. Electrochemical test results indicated that the Co-free materials delivered high capacity with excellent capacity retention and reasonable rate capability. In particular, Li(Ni0.9Mn0.1)O-2, which possesses the lowest cation mixing in the Li layers among samples, exhibited exceptionally high rate capacity (approximately 149 mAh g(-1) at 10 C rate) at 25 degrees C and high discharge capacity upon cycling under a severe condition, in the voltage range of 2.7-4.5 V at 55 degrees C. The cation mixing in Li(Ni0.9Mn0.1)O-2 increased slightly even after the extensive cycling at the elevated temperature, which is ascribed to the structural integrity induced from the optimized synthetic condition using the coprecipitation.

We show here by a combination of in situ microscopy and spectroscopy techniques that, in the presence of reactants, an oxide catalyst's chemical state and morphology are dynamically modified. The reduction of Cu2O films is studied under ambient pressures (AP) of CO. The use of complementary techniques allows us to identify intermediate surface oxide phases and determine how reaction fronts propagate across the surface by massive mass transfer of Cu atoms released during the reduction of the oxide phase in the presence of CO. High resolution in situ imaging by AP scanning tunneling microscopy (AP-STM) shows that the reduction of the oxide films is initiated at defects both on step edges and the center of oxide terraces.

TI Site-Specific Protein Transannination Using N-Methylpyridinium-4-carboxaldehyde SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID BIOMIMETIC TRANSAMINATION REACTION; MONOCLONAL-ANTIBODY; DRUG; CELLS; BIOCONJUGATION; LIBRARY AB The controlled attachment of synthetic groups to proteins is important for a number of fields, including therapeutics, where antibody drug conjugates are an emerging area of biologic medicines. We have previously reported a site-specific protein modification method using a transamination reaction that chemoselectively oxidizes the N-terminal amine of a polypeptide chain to a ketone or an aldehyde group. The newly introduced carbonyl can be used for conjugation to a synthetic group in one location through the formation of an oxime or a hydrazone linkage. To expand the scope of this reaction, we have used a combinatorial peptide library screening platform as a method to explore new transamination reagents while simultaneously identifying their optimal N-terminal sequences. N-Methylpyridinium-4-carboxaldehyde benzenesulfonate salt (Rapoport's salt, RS) was identified as a highly effective transamination reagent when paired with glutamate-terminal peptides and proteins. This finding establishes RS as a transamination reagent that is particularly well suited for antibody modification. Using a known therapeutic antibody, herceptin, it was demonstrated that RS can be used to modify the heavy chains of the wild-type antibody or to modify both the heavy and the light chains after N-terminal sequence mutation to add additional glutamate residues.

TI Identification of multi-phonon gamma-vibrational bands in odd-Z Nb-105 SO PHYSICAL REVIEW C LA English DT Article ID PROJECTED SHELL-MODEL; NEUTRON-RICH MO-106; ROTATIONAL BANDS; HIGH-SPIN; MASS NUCLEI; SPECTROSCOPY; DEFORMATION; EXCITATIONS; PARTICLE; FISSION AB Background: The odd-Z Nb-105 nucleus is located in the A = 100 neutron-rich region. The study of multi-phonon vibrational band structures is important for understanding nuclear structure in this region. Purpose: To search for multi-phonon gamma-vibrational bands in Nb-105. Methods: The high spin states of Nb-105 have been studied by measuring the prompt gamma rays emitted in the spontaneous fission of Cf-252. The data analysis is carried out using triple-and four-fold gamma coincidence methods. Results: A new level scheme of Nb-105 is established. The yrast band has been confirmed, and three new collective bands have been identified. Compared with previous results, a total of 14 new levels and 36 new gamma transitions are observed. Two bands built on 625.9 keV and 1231.9 keV levels are proposed as one-phonon- and two-phonon gamma-vibrational bands, respectively. The evidences for supporting assignments of the multi-phonon gamma-vibrational bands have been discussed. Triaxial projected shell model calculations for the gamma-vibrational band structures are found in good agreement with the experimental data, thus further supporting the gamma-vibrational interpretations for the experimental results in Nb-105. Conclusions: The one-phonon- and two-phonon gamma-vibrational bands have been identified in Nb-105. Our results provide new data to systematically understand the characteristics of the multi-phonon gamma-vibrational bands in the A = 100 neutron-rich region. C1 [Li, H. J.; Zhu, S. J.; Xiao, Z.

CA CDF Collaboration TI Search for the production of ZW and ZZ boson pairs decaying into charged leptons and jets in p(p)over-bar collisions at root s=1.96 TeV SO PHYSICAL REVIEW D LA English DT Article AB We present a measurement of the production cross section for ZW and ZZ boson pairs in final states with a pair of charged leptons, from the decay of a Z boson, and at least two jets, from the decay of a W or Z boson, using the full sample of proton-antiproton collisions recorded with the CDF II detector at the Tevatron, corresponding to 8.9 fb-1 of integrated luminosity. We increase the sensitivity to vector-boson decays into pairs of quarks using a neural-network discriminant that exploits the differences between the spatial spread of energy depositions and charged-particle momenta contained within the jet of particles originating from quarks and gluons. Additionally, we employ new jet energy corrections to Monte Carlo simulations that account for differences in the observed energy scales for quark and gluon jets. The number of signal events is extracted through a simultaneous fit to the dijet mass spectrum in three classes of events: events likely to contain jets with a heavy-quark decay, events likely to contain jets originating from light quarks, and events that fail these identification criteria. We determine the production cross section to be sigma(ZW+ZZ) = 2.5(-1.0)(+2.0) pb (<6.1 pb at the 95% confidence level), consistent with the standard model prediction of 5.1 pb. C1 [Chen, Y.

Here we report a novel mechanism through which a bootstrap current may be driven even in a collisionless plasma. In analogy with the neoclassical mechanism, in which the collisional equilibrium established between trapped and passing electrons produces a steady state current, we show that resonant scattering of electrons by drift wave microturbulence provides an additional means of determining the equilibrium between trapped and passing electrons and thus driving a bootstrap current. Employing a linearized Fokker-Planck collision operator, the plasma current in the presence of both collisions and resonant electron scattering is computed, allowing for the relative strength of these two mechanisms to be quantified as a function of collisionality and fluctuation amplitude.

Sarovar, Mohan Blume-Kohout, Robin TI Error Suppression and Error Correction in Adiabatic Quantum Computation: Techniques and Challenges SO PHYSICAL REVIEW X LA English DT Article AB Adiabatic quantum computation (AQC) has been lauded for its inherent robustness to control imperfections and relaxation effects. A considerable body of previous work, however, has shown AQC to be acutely sensitive to noise that causes excitations from the adiabatically evolving ground state. In this paper, we develop techniques to mitigate such noise, and then we point out and analyze some obstacles to further progress. First, we examine two known techniques that leverage quantum error-detecting codes to suppress noise and show that they are intimately related and may be analyzed within the same formalism. Next, we analyze the effectiveness of such error-suppression techniques in AQC, identify critical constraints on their performance, and conclude that large-scale, fault-tolerant AQC will require error correction, not merely suppression. Finally, we study the consequences of encoding AQC in quantum stabilizer codes and discover that generic AQC problem Hamiltonians rapidly convert physical errors into uncorrectable logical errors. We present several techniques to remedy this problem, but all of them require unphysical resources, suggesting that the adiabatic model of quantum computation may be fundamentally incompatible with stabilizer quantum error correction.

TI Towards a robust ad hoc data correction approach that yields reliable atomic pair distribution functions from powder diffraction data SO JOURNAL OF PHYSICS-CONDENSED MATTER LA English DT Article; Proceedings Paper CT 5th Workshop on Reverse Monte Carlo (RMC) Methods CY SEP 20-22, 2012 CL Budapest, HUNGARY ID SCATTERING; PROGRAM; REFINEMENT AB We examine the equations to obtain atomic pair distribution functions (PDFs) from x-ray, neutron and electron powder diffraction data with a view to obtaining reliable and accurate PDFs from the raw data using a largely ad hoc correction process. We find that this should be possible under certain circumstances that hold, to a reasonably good approximation, in many modern experiments. We describe a variational approach that could be applied to find data correction parameters that is highly automatable and should require little in the way of user inputs yet results in quantitatively reliable PDFs, modulo unknown scale factors that are often not of scientific interest when profile fitting models are applied to the data with scale factor as a parameter. We have worked on a particular implementation of these ideas and demonstrate that it yields PDFs that are of comparable quality to those obtained with the existing x-ray data reduction program PDFgetX2. This opens the door to rapid and highly automated processing of raw data to obtain PDFs. C1 [Billinge, Simon J.

TI Empirical potential structure refinement of semi-crystalline polymer systems: polytetrafluoroethylene and polychlorotrifluoroethylene SO JOURNAL OF PHYSICS-CONDENSED MATTER LA English DT Article ID NEUTRON-SCATTERING DATA; MONTE-CARLO-SIMULATION; SYNCHROTRON X-RAY; CRYSTAL-STRUCTURE; LOCAL-STRUCTURE; MOLTEN POLY(TETRAFLUOROETHYLENE); DIFFRACTION EXPERIMENTS; CRYSTALLIZATION; MODEL; MELT AB Empirical potential structure refinement (EPSR) simulations are performed on total neutron scattering data from powder samples of polytetrafluoroethylene (PTFE) and polychlorotrifluoroethylene (PCTFE), both at 300 K. Starting from single strands of polymer consisting of between 30 and 60 monomers of tetrafluoroethylene and chlorotrifluoroethylene in each case, hexagonal simulation cells are constructed consisting of an array 25 (5 x 5) such strands placed on a hexagonal lattice. Allowed simulation moves are polymer translation moves along all three Cartesian axes, whole polymer rotations about the polymer axis, and individual atom moves within each polymer. For PTFE a number of Bragg peaks are visible in the scattering data and these are found to be consistent with a lattice spacing a(= b) = 5.69(1) angstrom with a dihedral angle along the (helical) chain of 166 degrees which gives a repeat distance along the chain (c-axis) of similar to 19.6 angstrom. The positions of the Bragg peaks are well reproduced by this model, although there is a mismatch in the amplitudes of some of the higher order reflections between simulation and data. For PCTFE there is only one visible Bragg peak (100) which is well reproduced by a hexagonal lattice of atactic parallel polymers with a spacing of a(= b) = 6.37(1) angstrom. In this case the absence of distinct reflections along the polymer c-axis makes characterization of the internal dihedral angle difficult, but a model with a dihedral angle of 166 degrees was less successful at fitting the diffuse scattering than a model where this angle was set to 180 degrees, giving a nearly straight trans (zig-zag) structure. For PCTFE little change in structure could be discerned when the material was heated to 550 K, apart from a slight increase in lattice spacing. In both cases there is substantial diffuse scattering between the Bragg peaks, and this is correctly replicated by the EPSR simulations. C1 [Soper, A.

TI Unveiling Current Guanaco Distribution in Chile Based upon Niche Structure of Phylogeographic Lineages: Andean Puna to Subpolar Forests SO PLOS ONE LA English DT Article ID PSEUDO-ABSENCE DATA; SPECIES DISTRIBUTION; LAMA-GUANICOE; HABITAT MODELS; SOUTH-AMERICA; CONSERVATISM; EVOLUTION; PREDICTION; ECOLOGY; DESERT AB Niche description and differentiation at broad geographic scales have been recent major topics in ecology and evolution. Describing the environmental niche structure of sister taxa with known evolutionary trajectories stands out as a useful exercise in understanding niche requirements. Here we model the environmental niche structure and distribution of the recently resolved phylogeography of guanaco (Lama guanicoe) lineages on the western slope of the southern Andes. Using a maximum entropy framework, field data, and information on climate, topography, human density, and vegetation cover, we identify differences between the two subspecies (L. g. cacsilensis, L. g. guanicoe) and their intermediate-hybrid lineage, that most likely determine the distribution of this species. While aridity seems to be a major factor influencing the distribution at the species-level (annual precipitation <900 mm), we also document important differences in niche specificity for each subspecies, where distribution of Northern lineage is explained mainly by elevation (mean = 3,413 m) and precipitation seasonality (mean = 161 mm), hybrid lineage by annual precipitation (mean = 139 mm), and Southern subspecies by annual precipitation (mean = 553 mm), precipitation seasonality (mean = 21 mm) and grass cover (mean = 8.2%). Among lineages, we detected low levels of niche overlap: I (Similarity Index) = 0.06 and D (Schoener's Similarity Index) = 0.01; and higher levels when comparing Northern and Southern subspecies with hybrids lineage (I = 0.32-0.10 and D = 0.12-0.03, respectively). This suggests that important ecological and/or evolutionary processes are shaping the niche of guanacos in Chile, producing discrepancies when comparing range distribution at the species-level (81,756 km(2)) with lineages-level (65,321 km(2)). The subspecies-specific description of niche structure is provided here based upon detailed spatial distribution of the lineages of guanacos in Chile. Such description provides a scientific tool to further develop large scale plans for habitat conservation and preservation of intraspecific genetic variability for this far ranging South American camelid, which inhabits a diversity of ecoregion types from Andean puna to subpolar forests.

TI Oxygen Stoichiometry in the Geometrically Frustrated Kagome System YBaCo4O7+delta: Impact on Phase Behavior and Magnetism SO CHEMISTRY OF MATERIALS LA English DT Article DE complex cobalt oxide; oxygen storage; frustrated magnetism; miscibility gap ID COMPOUND YBACO4O7; CAPABILITY; ABSORPTION; COBALTITE; STABILITY AB Ternary Co oxides of the general formula RBaCo4O7+delta (where R = rare earth or Y) represent a family of materials that demonstrate impressive oxygen storage capabilities-as much as 3.25% by weight-at a relatively low temperature of similar to 350 degrees C. This behavior results from structural features amenable to formation of oxygen interstitials and the availability of wide channels offered by the structure for the facile diffusion and storage of oxygen. Remarkably, this material is also a model system for exploring geometrically frustrated magnetism due to the presence of interleaving Kagome and triangular cobalt sublattices. Unraveling the interplay of structure, oxygen stoichiometry, and phase behavior is important in optimizing the properties of this class of oxygen storage candidates and for broadening understanding of unusual magnetism. In this paper, we use thermogravimetric analysis, synchrotron X-ray diffraction, and neutron diffraction to explore how oxygen stoichiometry can be varied systematically and the impact of oxygen variability on phase behavior. In particular, we report the existence of a miscibility gap in lightly oxygenated YBaCo4O7+delta materials (0.0 < delta < 0.08) and the effects of the additional interstitial oxygen atoms on the material's nuclear structure and magnetism. Structural phase transitions that were previously observed in the pristine stoichiometric parent YBaCo4O7.0 material are suppressed by extra oxygen, leading to suppression of long-range magnetic order in favor of short-range correlations.

The films were characterized using XRD, UPS, Raman, and resistivity. The substrate lattice is yttrium stabilized zirconia and serves to stabilize the high temperature cubic phaseof UC2 (>1765 degrees C) at room temperature. The resistivity and UPS data indicate that UC2 has relatively low electrical conductivity consistent with HSE hybrid DFT calculations showing a narrow band gap. In situ XRD measurements show that the UC2 films oxidize to U3O8 above 200 degrees C.

The conjugated polymer additives, used with a slow solution crystallization approach, yield crystal structures that are not accessible by nonconjugated polymer additives and impart excellent long-range order. In both of the small molecule semiconductor/conjugated polymer blends studied here, previously unreported polymorphs of a small molecule semiconductor have been identified which also leads to improved charge transport in the absence of external alignment. These results open up a new exciting avenue to manipulate unit cell structure, long-range order, and charge transport of high performance, solution-processed, small molecule organic semiconductors.

CA PHENIX Collaboration TI Nuclear Modification of psi ', chi(c), and J/psi Production in d plus Au Collisions at root s(NN)=200 GeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID SUPPRESSION AB We present results for three charmonia states (psi' chi(c), and J/ psi) in d + Au collisions at vertical bar y vertical bar < 0.35 and root s(NN) = 200 GeV. We find that the modification of the psi' yield relative to that of the J/ psi scales approximately with charged particle multiplicity at midrapidity across p + A, d + Au, and A + A results from the Super Proton Synchrotron and the Relativistic Heavy Ion Collider. In large-impact-parameter collisions we observe a similar suppression for the psi' and J/ psi, while in small-impact-parameter collisions the more weakly bound psi' is more strongly suppressed. Owing to the short time spent traversing the Au nucleus, the larger psi' suppression in central events is not explained by an increase of the nuclear absorption owing to meson formation time effects.

TI Coexistence of Cluster Spin Glass and Superconductivity in Ba(Fe1-xCox)(2)As-2 for 0.060 <= x <= 0.071 SO PHYSICAL REVIEW LETTERS LA English DT Article ID IRON PNICTIDES; MAGNETIC ORDER; TRANSITION; BI2SR2CACU2O8+DELTA; CERHIN5 AB We present As-75 nuclear magnetic resonance data from measurements of a series of Ba(Fe1-xCox)(2)As-2 crystals with 0.00 <= x <= 0.075 that reveals the coexistence of frozen antiferromagnetic domains and superconductivity for 0.060 <= x <= 0.071. Although bulk probes reveal no long range antiferromagnetic order beyond x = 0.06, we find that the local spin dynamics reveal no qualitative change across this transition. The characteristic domain sizes vary by more than an order of magnitude, reaching a maximum variation at x = 0.06. This inhomogeneous glassy dynamics may be an intrinsic response to the competition between superconductivity and antiferromagnetism in this system. C1 [Dioguardi, A. P.; Crocker, J.; Shockley, A.

However, similar measurements on overdoped superconducting NaFe0.935Co0.045As find only a single sharp resonance at E-r = 7 meV. We connect these results with the observations of angle-resolved photoemission spectroscopy that the superconducting gaps in the electron Fermi pockets are anisotropic in the underdoped material but become isotropic in the overdoped case. Our analysis indicates that both the double neutron spin resonances and gap anisotropy originate from the orbital dependence of the superconducting pairing in the iron pnictides. Our discovery also shows the importance of the inelastic neutron scattering in detecting the multiorbital superconducting gap structures of iron pnictides.

TI Ctr2 regulates biogenesis of a cleaved form of mammalian Ctr1 metal transporter lacking the copper- and cisplatin-binding ecto-domain SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE uptake; platinum; protein regulation; endosome; lysosome ID SACCHAROMYCES-CEREVISIAE; CELLULAR ACCUMULATION; LIVING CELLS; HCTR1; PROTEIN; MECHANISMS; IRON; ACQUISITION; DEFICIENCY; YEAST AB Copper is an essential catalytic cofactor for enzymatic activities that drive a range of metabolic biochemistry including mitochondrial electron transport, iron mobilization, and peptide hormone maturation. Copper dysregulation is associated with fatal infantile disease, liver, and cardiac dysfunction, neuropathy, and anemia. Here we report that mammals regulate systemic copper acquisition and intracellular mobilization via cleavage of the copperbinding ecto-domain of the copper transporter 1 (Ctr1). Although full-length Ctr1 is critical to drive efficient copper import across the plasma membrane, cleavage of the ecto-domain is required for Ctr1 to mobilize endosomal copper stores. The biogenesis of the truncated form of Ctr1 requires the structurally related, previously enigmatic copper transporter 2 (Ctr2). Ctr2(-/-) mice are defective in accumulation of truncated Ctr1 and exhibit increased tissue copper levels, and X-ray fluorescence microscopy demonstrates that copper accumulates as intracellular foci. These studies identify a key regulatory mechanism for mammalian copper transport through Ctr2-dependent accumulation of a Ctr1 variant lacking the copper and cisplatin-binding ecto-domain.

TI Discrete symmetries and neutrino mass perturbations for theta(13) SO JOURNAL OF HIGH ENERGY PHYSICS LA English DT Article DE Neutrino Physics; CP violation ID MIXING ANGLES; QUARK; OSCILLATION; DEVIATIONS; PHASE AB The recent measurement of the third lepton mixing angle, theta(13), has shown that, although small compared to theta(12) and theta(23), it is much larger than anticipated in schemes that generate Tri-Bi-Maximal (TBM) or Golden Ratio (GR) mixing. We develop a model-independent formalism for perturbations away from exact TBM or GR mixing in the neutrino sector. Each resulting perturbation scheme reflects an underlying symmetry structure and involves a single complex parameter. We show that such perturbations can readily fit the observed value of theta(13), which is then correlated with a change in the other mixing angles. We also determine the implication for the lepton CP violating phases. For comparison we determine the predictions for Bi-Maximal mixing corrected by charged lepton mixing and we discuss the accuracy that will be needed to distinguish between the various schemes.

At 115 and 120 degrees C, we observe splitting of the principal Bragg peak, which we attribute to phase coexistence of hexagonal cylindrical and cubic double-gyroid structure. In the disordered phase, above 130 degrees C, we have characterized the dynamics of composition fluctuations via X-ray Photon correlation spectroscopy. Near the peak of the static structure factor, these fluctuations show stretched-exponential relaxations, characterized by a stretching exponent of about 0.36 for a range of temperatures immediately above the MST. The corresponding characteristic relaxation times vary exponentially with temperature, changing by a factor of 2 for each 2 degrees C change in temperature. At low wavevectors, the measured relaxations are diffusive with relaxation times that change by a factor of 2 for each 8 degrees C change in temperature.

TI Theory of the Miscibility of Fullerenes in Random Copolymer Melts SO MACROMOLECULES LA English DT Article ID INTEGRAL-EQUATION THEORY; WALLED CARBON NANOTUBES; POLYMER NANOCOMPOSITES; NONCOVALENT INTERACTIONS; DISPERSION; FLUIDS; IMPACT; C-60 AB We combine polymer integral equation theory and computational chemistry methods to study the interfacial structure, effective interactions, miscibility and spatial dispersion mechanism of fullerenes dissolved in specific random AB copolymer melts characterized by strong noncovalent electron donor-acceptor interactions with the nanofiller. A statistical mechanical basis is developed for designing random copolymers to optimize fullerene dispersion at intermediate copolymer compositions. Pair correlation calculations reveal a strong sensitivity of interfacial packing near the fullerene to copolymer composition and adsorption energy mismatch. The potential of mean force between fullerenes displays rich trends, often nonmonotonic with copolymer composition, reflecting a nonadditive competition between direct filler attractions and polymer-mediated bridging and steric stabilization. The spinodal phase diagrams are in qualitative agreement with recent solubility limit experimental observations on three systems, and testable predictions are made for other random copolymers. The distinctive nonmonotonic variation of miscibility with copolymer composition is found to be primarily a consequence of composition-dependent, spatially short-range attractions between the A and B monomers with the fullerene and nontrivial pair correlations. A remarkably rich, polymer-specific temperature dependence of the spinodal diagram is predicted, which reflects the thermal sensitivity of spatial correlations which can result in fullerene miscibility either increasing or decreasing with cooling. The calculations are contrasted with a simpler effective homopolymer model and the random structure Flory-Huggins model. The former appears to be qualitatively reasonable but can incur large quantitative errors since it misses preferential packing of monomers near nanopartides, while the latter appears to fail qualitatively due to its neglect of all spatial correlations.

TI Application of independent component analysis to ac dipole based optics measurement and correction at the Relativistic Heavy Ion Collider SO PHYSICAL REVIEW SPECIAL TOPICS-ACCELERATORS AND BEAMS LA English DT Article AB Correction of beta-beat is of great importance for performance improvement of high energy accelerators, like the Relativistic Hadron Ion Collider (RHIC). At RHIC, using the independent component analysis method, linear optical functions are extracted from the turn by turn beam position data of the ac dipole driven betatron oscillation. Despite the constraint of a limited number of available quadrupole correctors at RHIC, a global beta-beat correction scheme using a beta-beat response matrix method was developed and experimentally demonstrated. In both rings, a factor of 2 or better reduction of beta-beat was achieved within available beam time. At the same time, a new scheme of using horizontal closed orbit bump at sextupoles to correct beta-beat in the arcs was demonstrated in the Yellow ring of RHIC at beam energy of 255 GeV, and a peak beta-beat of approximately 7% was achieved.

X-ray scattering and polarization-dependent x-ray absorption spectroscopy measurements are performed to determine the crystal symmetry and extract the local Ni 3d orbital response, respectively, to understand the strain-induced distortions of the bulk structure. A strain-induced orbital polarization is found in NdNiO3 films, but is absent in LaNiO3 films. The difference in electronic structure is attributed to the bulk thermodynamic phases through group theoretical methods, which reveals that thin film perovskites retain a "memory" of their preferred electronic and structural configurations.

TI Electronic structure of carbon dioxide under pressure and insights into the molecular-to-nonmolecular transition SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE mineral physics; diamond anvil cell; inelastic x-ray scattering ID CRYSTAL-STRUCTURE; PHASE; CO2; GPA; NITROGEN; TEMPERATURES; SILICA AB Knowledge of the high-pressure behavior of carbon dioxide (CO2), an important planetary material found in Venus, Earth, and Mars, is vital to the study of the evolution and dynamics of the planetary interiors as well as to the fundamental understanding of the C-O bonding and interaction between the molecules. Recent studies have revealed a number of crystalline polymorphs (CO2-I to -VII) and an amorphous phase under high pressure-temperature conditions. Nevertheless, the reported phase stability field and transition pressures at room temperature are poorly defined, especially for the amorphous phase. Here we shed light on the successive pressure-induced local structural changes and the molecular-to-nonmolecular transition of CO2 at room temperature by performing an in situ study of the local electronic structure using X-ray Raman scattering, aided by first-principle exciton calculations. We show that the transition from CO2-I to CO2-III was initiated at around 7.4 GPa, and completed at about 17 GPa. The present study also shows that at similar to 37 GPa, molecular CO2 starts to polymerize to an extended structure with fourfold coordinated carbon and minor CO3 and CO-like species. The observed pressure is more than 10 GPa below previously reported. The disappearance of the minority species at 63(+/- 3) GPa suggests that a previously unknown phase transition within the nonmolecular phase of CO2 has occurred.

TI Enhanced fatigue endurance of metallic glasses through a staircase-like fracture mechanism SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE bulk amorphous alloy; fatigue life; damage tolerance ID SUPERCOOLED LIQUID REGION; BULK AMORPHOUS-ALLOYS; CRACK-GROWTH-BEHAVIOR; TOUGHNESS; CLOSURE; PROPAGATION; COMPOSITES; MODEL AB Bulk-metallic glasses (BMGs) are now candidate materials for structural applications due to their exceptional strength and toughness. However, their fatigue resistance can be poor and inconsistent, severely limiting their potential as reliable structural materials. As fatigue limits are invariably governed by the local arrest of microscopically small cracks at microstructural features, the lack of microstructure in monolithic glasses, often coupled with other factors, such as the ease of crack formation in shear bands or a high susceptibility to corrosion, can lead to low fatigue limits (some similar to 1/20 of their tensile strengths) and highly variable fatigue lives. BMG-matrix composites can provide a solution here as their duplex microstructures can arrest shear bands at a second phase to prevent cracks from exceeding critical size; under these conditions, fatigue limits become comparable with those of crystalline alloys. Here, we report on a Pd-based glass that similarly has high fatigue resistance but without a second phase. This monolithic glass displays high intrinsic toughness from extensive shear-band proliferation with cavitation and cracking effectively obstructed. We find that this property can further promote fatigue resistance through extrinsic crack-tip shielding, a mechanism well known in crystalline metals but not previously reported in BMGs, whereby cyclically loaded cracks propagate in a highly "zig-zag" manner, creating a rough "staircase-like" profile. The resulting crack-surface contact (roughness-induced crack closure) elevates fatigue properties to those comparable to crystalline alloys, and the accompanying plasticity helps to reduce flaw sensitivity in the glass, thereby promoting structural reliability.

Although this Edisonian approach is useful for a posteriori understanding of the factors governing assembly, it does not allow one to a priori design ssDNA-grafted colloids that will assemble into desired structures. Here we address precisely this design issue, and present an experimentally validated evolutionary optimization methodology that is not only able to reproduce the original phase diagram detailing regions of known crystals, but is also able to elucidate several previously unobserved structures. Although experimental validation of these structures requires further work, our early success encourages us to propose that this genetic algorithm-based methodology is a promising and rational materials-design paradigm with broad potential applications.

It is now apparent that protein multimers play an important role in RAF activation and tumor response to RAFis. However, the exact stoichiometry and cellular location of these multimers remain unclear because of the lack of technologies to visualize them. In the present work, we demonstrate that photoactivated localization microscopy (PALM), in combination with quantitative spatial analysis, provides sufficient resolution to directly visualize protein multimers in cells. Quantitative PALM imaging showed that CRAF exists predominantly as cytoplasmic monomers under resting conditions but forms dimers as well as trimers and tetramers at the cell membrane in the presence of active RAS. In contrast, N-terminal truncated CRAF (CatC) lacking autoinhibitory domains forms constitutive dimers and occasional tetramers in the cytoplasm, whereas a CatC mutant with a disrupted CRAF-CRAF dimer interface does not. Finally, artificially forcing CRAF to the membrane by fusion to a RAS CAAX motif induces multimer formation but activates RAF/MAPK only if the dimer interface is intact. Together, these quantitative results directly confirm the existence of RAF dimers and potentially higher-order multimers and their involvement in cell signaling, and showed that RAF multimer formation can result from multiple mechanisms and is a critical but not sufficient step for RAF activation.

First, it is hosted by a ciliated protist, Euplotes; bacterial symbionts of ciliates are still poorly known because of a lack of extensive molecular data. Second, the single species P. necessarius contains both symbiotic and free-living strains, allowing for a comparison between closely related organisms with different ecologies. Third, free-living P. necessarius strains are exceptional by themselves because of their small genome size, reduced metabolic flexibility, and high worldwide abundance in freshwater systems. We provide a comparative analysis of P. necessarius metabolism and explore the peculiar features of a genome reduction that occurred on an already streamlined genome. We compare this unusual system with current hypotheses for genome erosion in symbionts and free-living bacteria, propose modifications to the presently accepted model, and discuss the potential consequences of translesion DNA polymerase loss.

Here, we report first-principles calculations and Kinetic Monte Carlo simulations to describe oxygen binding, diffusion, and reactions on graphene in the presence of grain boundaries. We show that the defects attract and accumulate oxygen caused by the local strain. Moreover, we find that the reaction of a three-atom oxygen cluster, which consumes carbon atoms and creates vacancies in graphene, has a lower reaction barrier at grain boundaries than that on pristine graphene. Kinetic Monte Carlo simulations suggest that the dynamics of oxygen on graphene is controlled by two processes, oxygen reaction and migration, which depend on temperature and oxygen coverage. Because of the comparable activation barrier for both processes, etching at grain boundaries and the pristine region occurs simultaneously. (C) 2013 Elsevier Ltd. All rights reserved.

The new solid complexes [FeCl3(btaH)(2)] (1), [FeCl3(Mebta)(2)] (2), [FeCl3(5,6Me(2)btaH)(2)] (3) and [FeCl3(5Clb-taH)(2)]center dot 2(5ClbtaH) (4) have been isolated. The structures of the complexes have been determined by single-crystal, X-ray crystallography. The structures of 1-4 consist of mononuclear, high-spin 5-coordinate molecules; in addition, the crystal structure of 4 contains two lattice 5ClbtaH molecules per [FeCl3(5Clb-taH)(2)] unit. The coordinated benzotriazole molecules behave as monodentate ligands with their ligated atom being the nitrogen of the position 3 of the azole ring. The geometry at iron(III) is trigonal bipyramidal with the chlorido ligands occupying the equatorial sites. The crystal structures of the complexes are stabilized by stacking interactions and H bonds (for 1, 3 and 4 only). The new complexes were characterized by elemental analyses, magnetic susceptibilities at room temperature and spectroscopic (IR, far-IR, solid-state electronic UV/VIS/near-IR, Fe-57-Mossbauer, EPR only for complex 4) methods. All data are discussed in terms of the nature of bonding and the known structures. Complexes 1, 2 and 4 have been tested as homogeneous (MeCN) oxidation catalysts in the presence of the "green" H2O2 oxidant; they display moderate to high catalytic activity in the oxidation of several alkenes, cyclohexane and n-hexane, which is described in detail.

Overall, HgCr2S4 exhibits three reversible structural transitions under pressure: the starting Fd-3m phase adopts a tetragonal I4(1)/amd structure at 20GPa, an orthorhombic distortion occurs above 26 GPa, whereas a third structural transition takes place beyond 37 GPa. During the Fd-3m to I4(1)/amd structural transition, HgCr2S4 experiences a volume change of 4% which is unexpected from space group symmetry considerations alone. Furthermore, the Fd-3m to I4(1)/amd transformation appears to be concomitant with an insulator-to-metal transition whereas compression of HgCr2S4 leads to a gradual suppression of its ferromagnetism.

The low concentrations of Cr (<10 at. %) were selected in order to inhibit the complete conversion of the Fe-oxide shell to Cr2O3 and the Fe core to FeCr alloy. The magnetic interaction in Fe/Fe-oxide NCs (similar to 25 nm) can be controlled by antiferromagnetic Cr-dopant. We report the origin of sigma-FeCr phase at very low Cr concentration (2 at. %) unlike in previous studies, and the interaction reversal from dipolar to exchange interaction in watermelon-like Cr-doped core-shell NCs.

Here, we use heavy-ion and proton irradiation to create correlated and point defects to explore the vortex pinning behavior of each and combined constituent defects in the iron-based superconductor Ba0.6K0.4Fe2As2 and find that the pinning mechanisms are non-additive. The major effect of p-irradiation in mixed pinning landscapes is the generation of field-independent critical currents in very high fields. At 7 T parallel to c and 5 K, the critical current density exceeds 5 MA/cm(2). (C) 2013 AIP Publishing LLC. C1 [Kihlstrom, K. J.; Fang, L.; Jia, Y.; Shen, B.; Koshelev, A. E.; Welp, U.; Crabtree, G.

TI Experimental Realization of Josephson Junctions for an Atom SQUID SO PHYSICAL REVIEW LETTERS LA English DT Article ID BOSE-EINSTEIN CONDENSATION; QUANTUM SUPERPOSITION; ROTATION; STATES; QUBITS AB We report the creation of a pair of Josephson junctions on a toroidal dilute gas Bose-Einstein condensate (BEC), a configuration that is the cold atom analog of the well-known dc superconducting quantum interference device (SQUID). We observe Josephson effects, measure the critical current of the junctions, and find dynamic behavior that is in good agreement with the simple Josephson equations for a tunnel junction with the ideal sinusoidal current-phase relation expected for the parameters of the experiment. The junctions and toroidal trap are created with the painted potential, a time-averaged optical dipole potential technique which will allow scaling to more complex BEC circuit geometries than the single atom-SQUID case reported here. Since rotation plays the same role in the atom SQUID as magnetic field does in the dc SQUID magnetometer, the device has potential as a compact rotation sensor. C1 [Ryu, C.; Blackburn, P.

The corresponding 1,4-dihydropyridines coordinating to a Ru(II) complex in eta(2) mode through a C=C bond were quantitatively formed at the initial stage. The only exception observed was in the case of the 1-benzylpyridinium cation, where a mixture of two adducts with 1,4-dihydropyridine and 1,2-dihydropyridine was formed in the ratio 96:4. Cleavage of the Ru-(C=C) bond proceeded at a slower rate in all reactions, giving the corresponding dihydropyridine and [Ru(tpy)(bpy)(NCCH3)](2+) when acetonitrile was used as a solvent. Kinetic activation parameters for the adduct formation indicated that the 1,4-regioselectivities were induced by formation of sterically constrained structures.

CA CDF Collaboration TI Measurement of the top-quark pair-production cross section in events with two leptons and bottom-quark jets using the full CDF data set SO PHYSICAL REVIEW D LA English DT Article ID P(P)OVER-BAR COLLISIONS; COLLIDER DETECTOR; FERMILAB; QCD AB We present a measurement of the top-quark pair production cross section in proton-antiproton collisions at root s = 1.96 TeV. The data were collected at the Fermilab Tevatron by the CDF II detector and correspond to an integrated luminosity of 8.8 fb(-1), representing the complete CDF Run II data set. We select events consistent with the production of top-quark pairs by requiring the presence of two reconstructed leptons, an imbalance in the total event transverse momentum, and jets. At least one jet is required to be identified as consistent with the fragmentation of a bottom quark using a secondary-vertex-finding algorithm. The 246 candidate events are estimated to have a signal purity of 91%. We measure a cross section of sigma(t (t) over bar) = 7.09 +/- 0.84 pb, assuming a top-quark mass of 172.5 GeV/c(2). The results are consistent with the standard model as predicted by next-to-leading-order calculations. C1 [Chen, Y. C.; Hou, S.; Mitra, A.; Teng, P. K.; Wang, S.

TI Cascade gamma rays following capture of thermal neutrons on Cd-113 SO PHYSICAL REVIEW C LA English DT Article ID DANCE ARRAY AB Intensity distributions of cascade gamma-ray transitions following the capture of thermal neutrons by Cd-113 have been measured at the Los Alamos Neutron Science Center for various gamma-ray multiplicities. The experiment was carried out at the highly segmented 4 pi gamma-ray calorimeter-Detector for Advanced Neutron Capture Experiments ( DANCE). A measured two-dimensional spectrum of counts versus gamma-ray energy versus gamma-ray multiplicity, from the strongest resonance in the Cd-113( n,gamma) reaction at 0.178 eV has been compared to predictions from the statistical model. The best representation of the gamma-ray cascades following the capture of thermal neutrons on Cd-113 is presented. The intensity distribution of these cascades is of great importance for estimates of response to thermal neutrons of devices that use natural or enriched cadmium.

The set of materials includes those that have shown high O-2 uptake experimentally as well as a subset of more than 2000 structures previously screened for noble-gas uptake. While use of the general force field UFF is fruitful for noble-gas adsorption studies, its use is shown to be limited for the case of O-2 adsorptionone distinct limitation is a lack of sufficient O-2-metal interactions to be able to describe O-2 interaction with open metal sites. Nonetheless, those structures without open metal sites that have very small pores (<2.5 angstrom) show increased O-2/N-2 selectivity. Additionally, O-2/N-2 mixture simulations show that in some cases, H2O or N-2 can hinder O-2 uptake for NFMs with small pores due to competitive adsorption.

Group additivity based models linking the Arrhenius parameters to structural characteristics of the transition state have proven to be a valuable tool to obtain those data. In this work, group additivity values are presented to allow a broad range of CH and SH hydrogen abstraction reactions by S radicals to be modeled. Rate coefficients in the temperature range from 300 to 1500 K are obtained by using the CBS-QB3 method in the high-pressure limit and are corrected for tunneling and anharmonicity of rotation about the transitional bond. A total of 149 reactions are studied. From these reactions, a total of 52 group additivity values and 35 resonance corrections are derived. The general applicability of the group additivity method is demonstrated for a test set containing 25 reactions. At 300 K, rate coefficients are on average reproduced within a factor of 2.8. The mean absolute deviations on the Arrhenius parameters are 2 kJmol(-1) for the activation energy and 0.38 for log A in which A is the pre-exponential factor.

Using a gauge invariant regularization of high energy divergences by deforming the light-cone vectors of the effective action, we determine the two-loop self-energy of the reggeized gluon, after computing the master integrals involved using the Mellin-Barnes representations technique. The self-energy is further matched to QCD through a recently proposed subtraction prescription. The Regge trajectory of the gluon is then defined through renormalization of the reggeized gluon propagator with respect to high energy divergences. Our result is in agreement with previous computations in the literature, providing a non-trivial test of the effective action and the proposed subtraction and renormalization framework.

It is important to the ILC design effort to demonstrate that these tolerances can be achieved-ideally using a beam-based stability measurement. We developed a high resolution RF cavity Beam Position Monitor (BPM) system. A triplet of these BPMs, installed in the extraction line of the KEK Accelerator Test Facility (ATF) and tested with its ultra-low emittance beam, achieved a position measurement resolution of 15 nm. A metrology system for the three BPMs was subsequently installed. This system employed optical encoders to measure each BPM's position and orientation relative to a zero-coefficient of thermal expansion carbon fiber frame. We have demonstrated that the three BPMs behave as a rigid-body at the level of less than 5 nm. (C) 2013 Elsevier By. All rights reserved.

This is an important step in an effort to develop a detector capable of identifying the ionization signal resulting from nuclear recoils with energies of order a few keV and below. We obtained this result by observing the peaks in the energy spectrum at 2.82 keV and 0.27 keV, following the K- and L-shell electron capture decay of Ar-37 respectively. The (37)Ai- source preparation is described in detail, since it enables calibration that may also prove useful in dark matter direct detection experiments. An internally placed Fe-55 x-ray source simultaneously provided another calibration point at 5.9 keV. We discuss the ionization yield and electron recombination in liquid argon at those three calibration energies. Published by Elsevier BY. C1 [Sangiorgio, S.; Joshi, T.

TI Bi-spectral moderator for spallation sources optimized for instrument requirements SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Bi-spectral; Moderators; Optimization; MCNPX; ESS ID PERFORMANCE AB At a spallation neutron source, significant increase in the performance of neutron scattering instruments can be achieved if the target-moderator-reflector (TMR) and the following neutron guides are specifically tailored to the needs of different instrument classes. In order to define optimal quantities (e.g. positions of peak neutron flux, used wavelength band) for the Figure of Merit (FoM), a survey has been conducted at PSI covering the experience of the local instrument scientists. Based on this survey we introduce several FoMs which show the potential of tailoring the neutron spectrum to specific instrument needs. The developed methodology is adopted to optimize the top moderator in the conceptual design of the TMR of the European Spallation Source (ESS) Project. A parametrized geometry model of the ESS TMR is built in MCNPX and used within an optimization framework to study and optimize the moderator performance in the thermal and cold regions of the neutron spectrum. The results obtained with the optimized setup are compared to the ESS 2003 Project. Furthermore, experience is gathered while performing these simulations, e.g. the examination of the pulse shapes obtained with time-dependent calculations shows that for long-pulse target stations the peak brightness can with sufficient precision be obtained from time-independent calculations by scaling with the proton pulse duty factor.

Shock waves are generated using a high-power laser focused onto a thin foil target placed in close proximity to the test blocks. The fiber Fabry-Perot sensor appears capable of resolving the shock front with a rise time of 91 ns. The peak pressure is estimated, using a separate shadowgraphy measurement, to be 3.4 GPa.

The search for CLFV has continued from the early 1940s, when the muon was identified as a separate particle, until today. Certainly in the LHC era the motivations for continued searches are clear and have been covered in many reviews. This review is focused on the experimental history with a view toward how these searches might progress. We examine the status of searches for charged lepton flavor violation in the muon, tau, and other channels, and then examine the prospects for new efforts over the next decade. Finally, we examine what paths might be taken after the conclusion of upcoming experiments and what facilities might be required. (C) 2013 Elsevier B.V. All rights reserved. C1 [Bernstein, R.

These observations primarily sample rest-frame timescales of 1-3.7 yr over which significant rearrangement of the BAL wind is expected. We derive a number of observational results on, e. g., the frequency of BAL variability, the velocity range over which BAL variability occurs, the primary observed form of BAL-trough variability, the dependence of BAL variability upon timescale, the frequency of BAL strengthening versus weakening, correlations between BAL variability and BAL-trough profiles, relations between C IV and Si IV BAL variability, coordinated multi-trough variability, and BAL variations as a function of quasar properties. We assess implications of these observational results for quasar winds. Our results support models where most BAL absorption is formed within an order-of-magnitude of the wind-launching radius, although a significant minority of BAL troughs may arise on larger scales. We estimate an average lifetime for a BAL trough along our line-of-sight of a few thousand years. BAL disappearance and emergence events appear to be extremes of general BAL variability, rather than being qualitatively distinct phenomena. We derive the parameters of a random-walk model for BAL EW variability, finding that this model can acceptably describe some key aspects of EW variability. The coordinated trough variability of BAL quasars with multiple troughs suggests that changes in "shielding gas" may play a significant role in driving general BAL variability. C1 [Ak, N.

Unfortunately, in spite of their extreme luminosities, individual Population III (Pop III) stars will likely remain beyond the reach of direct observation for decades to come. However, their properties could be revealed by their supernova explosions, which may soon be detected by a new generation of near-IR (NIR) observatories such as JWST and WFIRST. We present light curves and spectra for Pop III pair-instability supernovae calculated with the Los Alamos radiation hydrodynamics code RAGE. Our numerical simulations account for the interaction of the blast with realistic circumstellar envelopes, the opacity of the envelope, and Lyman absorption by the neutral intergalactic medium at high redshift, all of which are crucial to computing the NIR signatures of the first cosmic explosions. We find that JWST will detect pair-instability supernovae out to z greater than or similar to 30, WFIRST will detect them in all-sky surveys out to z similar to 15-20, and LSST and Pan-STARRS will find them at z less than or similar to 7-8. The discovery of these ancient explosions will probe the first stellar populations and reveal the existence of primitive galaxies that might not otherwise have been detected.

In this scenario, a few protogalaxies form in the presence of strong Lyman-Werner UV backgrounds that quench H-2 formation in their constituent halos, preventing them from forming stars or blowing heavy elements into the intergalactic medium prior to formation. At masses of 10(8) M-circle dot and virial temperatures of 10(4) K, gas in these halos rapidly cools by H lines, in some cases forming 10(4)-10(6) M-circle dot Population III stars and, a short time later, the seeds of SMBHs. Instead of collapsing directly to black holes (BHs), some of these stars died in the most energetic thermonuclear explosions in the universe. We have modeled the explosions of such stars in the dense cores of line-cooled protogalaxies in the presence of cosmological flows. In stark contrast to the explosions in diffuse regions in previous simulations, these supernovae briefly engulf the protogalaxy, but then collapse back into its dark matter potential. Fallback drives turbulence that efficiently distributes metals throughout the interior of the halo and fuels the rapid growth of nascent BHs at its center. The accompanying starburst and X-ray emission from these line-cooled galaxies easily distinguish them from more slowly evolving neighbors and might reveal the birthplaces of SMBHs on the sky.

We determine distances using the photometric parallax method, and in this context systematic effects exist which could potentially impact the determination of the number density profile with height from the Galactic plane- and ultimately affect a number density north-south asymmetry. They include: (1) the calibration of the various photometric parallax relations, (2) the ability to separate dwarfs from giants in our sample, (3) the role of stellar population differences such as age and metallicity, (4) the ability to determine the offset of the Sun from the Galactic plane, and (5) the correction for reddening from dust in the Galactic plane, though our stars are at high Galactic latitudes. We find the various analyzed systematic effects to have a negligible impact on our observed asymmetry, and using a new and larger sample of stars we confirm and refine the earlier discovery of Widrow et al. of a significant Galactic north-south asymmetry in the stellar number density distribution.

TI The crystal structures of the tri-functional Chloroflexus aurantiacus and bi-functional Rhodobacter sphaeroides malyl-CoA lyases and comparison with CitE-like superfamily enzymes and malate synthases SO BMC STRUCTURAL BIOLOGY LA English DT Article DE Malyl-CoA lyase; Malate synthase; Citrate lyase; CitE ID COENZYME-A LYASE; CITRATE LYASE; MYCOBACTERIUM-TUBERCULOSIS; ESCHERICHIA-COLI; METHYLMALYL-COENZYME; ANGSTROM RESOLUTION; HALOFERAX-VOLCANII; ISOCITRATE LYASE; PROSTHETIC GROUP; ACETYL-COENZYME AB Background: Malyl-CoA lyase (MCL) is a promiscuous carbon-carbon bond lyase that catalyzes the reversible cleavage of structurally related Coenzyme A (CoA) thioesters. This enzyme plays a crucial, multifunctional role in the 3-hydroxypropionate bi-cycle for autotrophic CO2 fixation in Chloroflexus aurantiacus. A second, phylogenetically distinct MCL from Rhodobacter sphaeroides is involved in the ethylmalonyl-CoA pathway for acetate assimilation. Both MCLs belong to the large superfamily of CitE-like enzymes, which includes the name-giving beta-subunit of citrate lyase (CitE), malyl-CoA thioesterases and other enzymes of unknown physiological function. The CitE-like enzyme superfamily also bears sequence and structural resemblance to the malate synthases. All of these different enzymes share highly conserved catalytic residues, although they catalyze distinctly different reactions: C-C bond formation and cleavage, thioester hydrolysis, or both (the malate synthases). Results: Here we report the first crystal structures of MCLs from two different phylogenetic subgroups in apo- and substrate-bound forms. Both the C. aurantiacus and the R. sphaeroides MCL contain elaborations on the canonical beta(8)/alpha(8) TIM barrel fold and form hexameric assemblies. Upon ligand binding, changes in the C-terminal domains of the MCLs result in closing of the active site, with the C-terminal domain of one monomer forming a lid over and contributing side chains to the active site of the adjacent monomer. The distinctive features of the two MCL subgroups were compared to known structures of other CitE-like superfamily enzymes and to malate synthases, providing insight into the structural subtleties that underlie the functional versatility of these enzymes. Conclusions: Although the C. aurantiacus and the R. sphaeroides MCLs have divergent primary structures (similar to 37% identical), their tertiary and quaternary structures are very similar. It can be assumed that the C-C bond formation catalyzed by the MCLs occurs as proposed for malate synthases. However, a comparison of the two MCL structures with known malate synthases raised the question why the MCLs are not also able to hydrolyze CoA thioester bonds. Our results suggest the previously proposed reaction mechanism for malate synthases may be incomplete or not entirely correct. Further studies involving site-directed mutagenesis based on these structures may be required to solve this puzzling question.

To identify host genes that are targeted by Yersinia during the infection process, we performed an RNA interference (RNAi) screen based on recovery of host NF-kappa B-mediated gene activation in response to TNF-a stimulation upon Y. enterocolitica infection. Results: We screened shRNAs against 782 genes in the human kinome and 26 heat shock genes, and identified 19 genes that exhibited >= 40% relative increase in NF-kappa B reporter gene activity. The identified genes function in multiple cellular processes including MAP and ERK signaling pathways, ion channel activity, and regulation of cell growth. Pre-treatment with small molecule inhibitors specific for the screen hits c-KIT and CKII recovered NF-kappa B gene activation and/or pro-inflammatory TNF-a cytokine release in multiple cell types, in response to either Y. enterocolitica or Y. pestis infection. Conclusions: We demonstrate that pathogenic Yersinia exploits c-KIT signaling in a T3SS-dependent manner to downregulate expression of transcription factors EGR1 and RelA/p65, and pro-inflammatory cytokines. This study is the first major functional genomics RNAi screen to elucidate virulence mechanisms of a pathogen that is primarily dependent on extracellular-directed immunomodulation of host signaling pathways for suppression of host immunity.

CA ALICE Collaboration TI Charmonium and e(+)e(-) pair photoproduction at mid-rapidity in ultra-peripheral Pb-Pb collisions at root s(NN)=2.76 TeV SO EUROPEAN PHYSICAL JOURNAL C LA English DT Article ID J/PSI PHOTOPRODUCTION; PHYSICS; HERA; LHC AB The ALICE Collaboration at the LHC has measured the J/psi and psi' photoproduction at mid-rapidity in ultra-peripheral Pb-Pb collisions at root s(NN) = 2.76 TeV. The charmonium is identified via its leptonic decay for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 23 mu b(-1). The cross section for coherent and incoherent J/psi production in the rapidity interval -0.9 < y < 0.9, are d sigma(coh)(J/psi)/dy = 2.38(-0.24)(+0.34)(sta + sys) mb and d sigma(inc)(J/psi)/dy = 0.98(-0.17)(+0.19)(sta + sys) mb and , respectively. The results are compared to theoretical models for J/psi production and the coherent cross section is found to be in good agreement with those models incorporating moderate nuclear gluon shadowing at Bjorken-x around 10(-3), such as EPS09 parametrization. In addition the cross section for the process gamma gamma -> e(+)e(-) has been measured and found to be in agreement with models implementing QED at leading order.

Results: The AfFtn K150A/R151A double mutant forms a closed octahedral assembly with reduced iron release rates relative to the tetrahedral assembly. Conclusion: The K150A/R151A substitution alters the symmetry type of the ferritin cage. Significance: The AfFtn can be modulated for tuning molecular release from the cavity. Archaeoglobus fulgidus ferritin (AfFtn) is the only tetracosameric ferritin known to form a tetrahedral cage, a structure that remains unique in structural biology. As a result of the tetrahedral (2-3) symmetry, four openings (approximate to 45 in diameter) are formed in the cage. This open tetrahedral assembly contradicts the paradigm of a typical ferritin cage: a closed assembly having octahedral (4-3-2) symmetry. To investigate the molecular mechanism affecting this atypical assembly, amino acid residues Lys-150 and Arg-151 were replaced by alanine. The data presented here shed light on the role that these residues play in shaping the unique structural features and biophysical properties of the AfFtn. The x-ray crystal structure of the K150A/R151A mutant, solved at 2.1 resolution, indicates that replacement of these key residues flips a symmetry switch. The engineered molecule no longer assembles with tetrahedral symmetry but forms a typical closed octahedral ferritin cage. Small angle x-ray scattering reveals that the overall shape and size of AfFtn and AfFtn-AA in solution are consistent with those observed in their respective crystal structures. Iron binding and release kinetics of the AfFtn and AfFtn-AA were investigated to assess the contribution of cage openings to the kinetics of iron oxidation, mineralization, or reductive iron release. Identical iron binding kinetics for AfFtn and AfFtn-AA suggest that Fe2+ ions do not utilize the triangular pores for access to the catalytic site. In contrast, relatively slow reductive iron release was observed for the closed AfFtn-AA, demonstrating involvement of the large pores in the pathway for iron release.

TI Human-Like Eukaryotic Translation Initiation Factor 3 from Neurospora crassa SO PLOS ONE LA English DT Article ID PROTEIN-SYNTHESIS; FACTOR EIF3; SACCHAROMYCES-CEREVISIAE; ELECTRON-MICROSCOPY; MASS-SPECTROMETRY; NEW-GENERATION; H-SUBUNIT; COMPLEX; YEAST; REVEALS AB Eukaryotic translation initiation factor 3 (eIF3) is a key regulator of translation initiation, but its in vivo assembly and molecular functions remain unclear. Here we show that eIF3 from Neurospora crassa is structurally and compositionally similar to human eIF3. N. crassa eIF3 forms a stable 12-subunit complex linked genetically and biochemically to the 13th subunit, eIF3j, which in humans modulates mRNA start codon selection. Based on N. crassa genetic analysis, most subunits in eIF3 are essential. Subunits that can be deleted (e, h, k and l) map to the right side of the eIF3 complex, suggesting that they may coordinately regulate eIF3 function. Consistent with this model, subunits eIF3k and eIF3l are incorporated into the eIF3 complex as a pair, and their insertion depends on the presence of subunit eIF3h, a key regulator of vertebrate development. Comparisons to other eIF3 complexes suggest that eIF3 assembles around an eIF3a and eIF3c dimer, which may explain the coordinated regulation of human eIF3 levels. Taken together, these results show that Neurospora crassa eIF3 provides a tractable system for probing the structure and function of human-like eIF3 in the context of living cells. C1 [Smith, M.

TI Retention of alpha-helical structure by HDL mimetic peptide ATI-5261 upon extensive dilution represents an important determinant for stimulating ABCA1 cholesterol efflux with high efficiency SO BIOCHEMICAL AND BIOPHYSICAL RESEARCH COMMUNICATIONS LA English DT Article DE HDL mimetic peptides; Cholesterol efflux; alpha-Helix; Macrophages; Reverse cholesterol transport; Atherosclerosis; Therapeutic peptides ID HIGH-DENSITY-LIPOPROTEIN; APOLIPOPROTEIN-A-I; CELLULAR CHOLESTEROL; APOA-I; LYSINE MODIFICATION; AMPHIPATHIC HELIX; TANGIER-DISEASE; ELEVATED LEVELS; LIPID-BINDING; TRANSPORT AB ATI-5261 is a novel, single-helix peptide that stimulates cellular cholesterol efflux with high potency similar to native apolipoproteins on a molar basis. Presently we investigated structural features of the peptide that conferred cholesterol efflux activity. Analogs of ATI-5261 with amino acids arranged in reverse order or with individual arginine (R) to glutamine (Q) substitutions (i.e. R3Q, R14Q or R23Q) stimulated ABCA1 dependent cholesterol efflux similar to ATI-5261. Consequently, neither the presence of specific positively charged residues nor their specific arrangement along the length of the peptide was necessary for mediating cholesterol efflux. Similarly, peptides composed of all D-amino acids stimulated cholesterol efflux efficiently, indicating a stereospecific component was not required for promotion of cholesterol efflux from macrophages. Removal of two or more positively charged residues (R3, 14 -> Q and R3, 14, 23 -> Q) however, greatly reduced the ability of ATI-5261 to mediate cellular cholesterol efflux. This was accompanied by a loss of alpha-helical structure upon dilution, indicating the secondary structure of individual peptide strands was important for stimulating cholesterol efflux. Surprisingly, peptides with removal of two or more positively charged residues retained the ability to bind phospholipid and adopt an alpha-helical structure. These data indicate that the propensity of a hydrophobic peptide to form an amphipathic alpha-helix is not sufficient to mediate cellular cholesterol efflux. Efficient stimulation of cholesterol efflux requires that ATI-5261 retain alpha-helical structure upon dilution. Published by Elsevier Inc.

CA D0 Collaboration TI Measurement of the muon charge asymmetry in p(p)over-bar -> W + X -> mu nu + X events at root s=1.96 TeV SO PHYSICAL REVIEW D LA English DT Article ID HADRON COLLIDERS; COLLISIONS; DETECTOR; DECAY; TEV AB We present a measurement of the muon charge asymmetry from the decay of the W boson via W -> mu nu using 7: 3 fb(-1) of integrated luminosity collected with the D0 detector at the Fermilab Tevatron Collider at root s = 1.96 TeV. The muon charge asymmetry is presented in two kinematic regions in muon transverse momentum and event missing transverse energy: (p(T)(mu) > 25 GeV, E-T > 25 GeV) and (p(T)(mu) > 35 GeV, E-T > 35 GeV). The measured asymmetries are compared with theory predictions made using three parton distribution function sets. The data at p(T)(mu) > 35 GeV, E-T > 35 GeV, and larger values of vertical bar eta(mu)vertical bar favor an increased d(x)/u(x) ratio at higher values of x than is predicted. C1 [Maciel, A. K.

A minimal extension requires a singlet fermion X for dark matter and a singlet scalar S. With two or more hidden sector fermions, the scenario can lead to nucleon decay into dark matter with a lifetime of order 10(34-36) yr, which is relevant for current or future experiments. The correct multicomponent relic density can be obtained if dark matter fermions couple to a sub-GeV vector boson that weakly interacts with the standard model through mixing. The typical inflationary scale in the scenario is of order 10(16) GeV which suggests that tensor mode perturbations could potentially be within observational reach.

TI Multiple solutions for the fermion mass function in QED3 SO PHYSICAL REVIEW D LA English DT Article ID SCHWINGER-DYSON EQUATIONS; GAUGE FIELD-THEORIES; QUANTUM ELECTRODYNAMICS; SYMMETRY-BREAKING; QUENCHED QED3; SPECTRUM; QCD; PROPAGATORS; CONFINEMENT; COLLOCATION AB Theories that support dynamical generation of a fermion mass gap are of widespread interest. The phenomenon is often studied via the Dyson-Schwinger equation for the fermion self-energy, i.e., the gap equation. When the rainbow truncation of that equation supports dynamical mass generation, it typically also possesses a countable infinity of simultaneous solutions for the dressed-fermion mass function, solutions which may be ordered by the number of zeros they exhibit. These features can be understood via the theory of nonlinear Hammerstein integral equations. Using QED3 as an example, we demonstrate the existence of a large class of gap-equation truncations that possess solutions with damped oscillations. We suggest that there is a larger class, quite probably including the exact theory, which does not. The structure of the dressed fermion-gauge boson vertex is an important factor in deciding the issue.

TI Anisotropic dynamics of water ultraconfined in macroscopically oriented channels of single-crystal beryl: A multifrequency analysis SO PHYSICAL REVIEW E LA English DT Article ID ELASTIC NEUTRON-SCATTERING; HYDRATION WATER; MOLECULAR-DYNAMICS; PARTICLE DYNAMICS; SURFACE-WATER; SLOW DYNAMICS; SUPERCOOLED WATER; PROTON DIFFUSION; PURPLE MEMBRANE; CONFINED SPACE AB The properties of fluids can be significantly altered by the geometry of their confining environments. While there has been significant work on the properties of such confined fluids, the properties of fluids under ultraconfinement, environments where, at least in one plane, the dimensions of the confining environment are similar to that of the confined molecule, have not been investigated. This paper investigates the dynamic properties of water in beryl (Be3Al2Si6O18), the structure of which contains approximately 5-angstrom-diam channels parallel to the c axis. Three techniques, inelastic neutron scattering, quasielastic neutron scattering, and dielectric spectroscopy, have been used to quantify these properties over a dynamic range covering approximately 16 orders of magnitude. Because beryl can be obtained in large single crystals we were able to quantify directional variations, perpendicular and parallel to the channel directions, in the dynamics of the confined fluid. These are significantly anisotropic and, somewhat counterintuitively, show that vibrations parallel to the c-axis channels are significantly more hindered than those perpendicular to the channels. The effective potential for vibrations in the c direction is harder than the potential in directions perpendicular to it. There is evidence of single-file diffusion of water molecules along the channels at higher temperatures, but below 150 K this diffusion is strongly suppressed. No such suppression, however, has been observed in the channel-perpendicular direction. Inelastic neutron scattering spectra include an intramolecular stretching O-H peak at similar to 465 meV. As this is nearly coincident with that known for free water molecules and approximately 30 meV higher than that in liquid water or ice, this suggests that there is no hydrogen bonding constraining vibrations between the channel water and the beryl structure. However, dielectric spectroscopic measurements at higher temperatures and lower frequencies yield an activation energy for the dipole reorientation of 16.4 +/- 0.14 kJ/mol, close to the energy required to break a hydrogen bond in bulk water. This may suggest the presence of some other form of bonding between the water molecules and the structure, but the resolution of the apparent contradiction between the inelastic neutron and dielectric spectroscopic results remains uncertain.

Typical data from simulations are limited to times of 1 to 10 ns, and over this time period the calculated MSD continues to increase without a clear limiting value. The proposed method consists of fitting a model to MD simulation-derived values of the incoherent intermediate neutron scattering function, I-inc(Q, t), for finite times. The infinite-time MSD, < r(2)>, appears as a parameter in the model and is determined by fits of the model to the finite-time I-inc(Q, t). Specifically, the < r(2)> is defined in the usual way in terms of the Debye-Waller factor as (Q, t = infinity) = exp(-Q(2)< r(2)>/3). The method is illustrated by obtaining the intrinsic MSD < r(2)> of hydrated lysozyme powder (h = 0.4 g water/g protein) over a wide temperature range. The intrinsic < r(2)> obtained from data out to 1 and to 10 ns is found to be the same. The intrinsic < r(2)> is approximately twice the value of the MSD that is reached in simulations after times of 1 ns which correspond to those observed using neutron instruments that have an energy resolution width of 1 mu eV.

The BEC is then the first impurity host medium known to exhibit both Landau-Pekar polaron states akin to that of self-localized electrons in a dielectric lattice and self-localized bubble polaron states. We find that the neutral BEC-impurity system is fully characterized by only two dimensionless coupling constants and that a single BEC impurity can be steered adiabatically from the Landau-Pekar to the bubble region. The adiabatic change is that of a crossover, not a transition. C1 [Blinova, A. A.; Boshier, M. G.] Los Alamos Natl Lab, Div Phys, Los Alamos, NM 87545 USA. [Blinova, A.

The optical properties of the cavity walls are described in terms of realistic models for effective permittivity and permeability. Surface polaritons, i.e., electromagnetic modes that have at least partly an evanescent character, are shown to dominate the Casimir interaction at small separations. We analyze in detail the s-polarized polaritons, which are a characteristic feature of a magnetodielectric configuration, and discuss their role in the repulsive Casimir force.

At ambient pressure, CeZn11 orders antiferromagnetically at T-N = 2 K. The pressure dependence of the resistivity reveals an increase of the Kondo effect. We determine the pressure evolution of the magnetic exchange interaction between conduction and localized 4f electrons. It qualitatively reproduces the pressure evolution of the magnetic ordering temperature T-O1 (with T-O1 = T-N at ambient pressure). In addition to T-O1, a new anomaly T-O2 appears under pressure. Both anomalies are found to increase with applied pressure up to 4.9 GPa, indicating that CeZn11 is far from a pressure induced quantum critical point. Complex T-H phase diagrams are obtained under pressure which reveal the instability of the ground state in this compound.

We discovered that oxygen (O) on the Cu surface substantially decreased the graphene nucleation density by passivating Cu surface active sites. Control of surface O enabled repeatable growth of centimeter-scale single-crystal graphene domains. Oxygen also accelerated graphene domain growth and shifted the growth kinetics from edge-attachment-limited to diffusion-limited. Correspondingly, the compact graphene domain shapes became dendritic. The electrical quality of the graphene films was equivalent to that of mechanically exfoliated graphene, in spite of being grown in the presence of O.

The electrical conductivity in such a device depends on heat dissipation and partitioning inside the device and was studied comparatively for suspended and supported device architectures. The appearance of the exhaustion region in the temperature-dependent resistivity of a Joule-heated nanowire was used as a temperature marker for implementation of the quasi-constant temperature operation mode. At low pressures, the sensor is idle due to dominant heat dissipation from the nanowire to the substrate and/ or electrodes. Above ca. 10 Torr the sensitivity to gases has a strong dependence on pressure as well as on the type of gas and is determined by conductive heat transfer between the nanowire surface and ambient. This implies that, in contrast to macroscopic devices, the heat dissipation via the convection mechanism does not contribute significantly to the heat transfer from the self-heated nanowire. The thermal sensitivity of the sensor to reactive gases depends on the effectiveness of the particular endothermic/ exothermic reaction at the surface of the nanowire and was explored for the case of acetone-air mixture. The strong coupling of the electrical and thermal properties in the individual Joule-heated semiconducting nanowire allows fabrication of power-efficient multi-parametric nanoscopic gas/pressure sensors that are analogs of Pirani and pellistor type detectors.

The properties of interest include the mean energy required to create an e-h pair, W, Fano factor, F, the maximum theoretical light yield, and the spatial distribution of e-h pairs resulting from gamma-ray excitation. Although W and F vary with incident photon energy at low energies, they tend to constant values at energies higher than 1 keV. W is determined to be 18.9 and 19.8 eV for BaF2 and CaF2, respectively, in agreement with published data. The e-h pair spatial distributions exhibit a linear distribution along the fast electron tracks with high e-h pair densities at the end of the tracks. Most e-h pairs are created by interband transition and plasmon excitation in both scintillators, but the e-h pairs along fast electron tracks in BaF2 are slightly clustered, forming nanoscale domains and resulting in the higher e-h pair densities than in CaF2. Combining the maximum theoretical light yields calculated for BaF2 and CaF2 with those obtained for CsI and NaI shows that the theoretical light yield decreases linearly with increasing band gap energy.

TI Field ionization characteristics of an ion source array for neutron generators SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID CURRENT-VOLTAGE CHARACTERISTICS; MICROSCOPE; DESORPTION; H2 AB A new deuterium ion source is being developed to improve the performance of existing compact neutron generators. The ion source is a microfabricated array of metal tips with an integrated gate (i.e., grid) and produces deuterium ions by field ionizing (or field desorbing) a supply of deuterium gas. Deuterium field ion currents from arrays at source temperatures of 77K and 293K are studied. Ion currents from single etched-wire tips operating under the same conditions are used to help understand array results. I-F characteristics of the arrays were found to follow trends similar to those of the better understood single etched-wire tip results; however, the fields achieved by the arrays are limited by electrical breakdown of the structure. Neutron production by field ionization at 293K was demonstrated for the first time from microfabricated array structures with integrated gates. (c) 2013 AIP Publishing LLC. C1 [Johnson, B.

TI Microcavity-array superhydrophobic surfaces: Limits of the model SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID LOTUS LEAF; WETTABILITY; WATER AB Superhydrophobic surfaces formed of microcavities can be designed with specific desired advancing and receding contact angles using a new model described by us in prior work. Here, we discuss the limits of validity of the model, and explore the application of the model to surfaces fabricated with small cavities of radius 250 nm and with large cavities of radius 40 mu m. The Wenzel model is discussed and used to calculate the advancing and receding contact angles for samples for which our model cannot be applied. We also consider the case of immersion of a sample containing microcavities in pressurized water. A consideration that then arises is that the air inside the cavities can be dissolved in the water, leading to complete water invasion into the cavities and compromising the superhydrophobic character of the surface. Here, we show that this effect does not destroy the surface hydrophobia when the surface is subsequently removed from the water. (C) 2013 AIP Publishing LLC. C1 [Salvadori, M. C.; Teixeira, F.

A complete pressure (P)-volume (V)-temperature (T) equation of state (EOS) is determined based on the experiment, which includes temperature derivatives of elastic bulk modulus (at both constant pressure and constant volume) and pressure dependence of thermal expansivity. From this EOS, we calculate thermal pressure, heat capacity at constant volume, and thermodynamic Gru uneisen parameter as a function of temperature. Above similar to 600 K, our results show notable deviation from theoretical predictions using the quasiharmonic and local-density approximations, indicating that the free energy calculations need to be further improved within the current scheme of approximations.

TI Relative energies, structures, vibrational frequencies, and electronic spectra of pyrylium cation, an oxygen-containing carbocyclic ring isoelectronic with benzene, and its isomers SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID BASIS-SETS; CHEMISTRY; DENSITY; OXIDATION; KINETICS; IONS AB We have studied relative energies, structures, rotational, vibrational, and electronic spectra of the pyrylium cation, an oxygen-containing six-membered carbocyclic ring, and its six isomers, using ab initio quantum chemical methods. Isoelectronic with benzene, the pyrylium cation has a benzenoid structure and is the global minimum on the singlet potential energy surface of C5H5O+. The second lowest energy isomer, the furfuryl cation, has a five membered backbone akin to a sugar, and is only 16 kcal mol(-1) above the global minimum computed using coupled cluster theory with singles, doubles, and perturbative triple excitations (CCSD(T)) with the correlation consistent cc-pVTZ basis set. Other isomers are 25, 26, 37, 60, and 65 kcal mol(-1) above the global minimum, respectively, at the same level of theory. Lower level methods such as density functional theory (B3LYP) and second order Moller-Plesset perturbation theory performed well when tested against the CCSD(T) results. The pyrylium and furfuryl cations, although separated by only 16 kcal mol(-1), are not easily interconverted, as multiple bonds must be broken and formed, and the existence of more than one transition state is likely. Additionally, we have also investigated the asymptotes for the barrierless ion-molecule association of molecules known to exist in the interstellar medium that may lead to formation of the pyrylium cation.

We establish that there is considerable conformational flexibility to the model structure, even at relatively low temperatures, which influences the predicted spectroscopic properties.

Laser induced fluorescence spectra were obtained in the 850- 650 nm region. Although the 000 band was not observed, strong (3)n(0) and 2(0)(1)3(0)(n) progressions and 3(1) hot bands could be assigned in the HPS LIF spectrum. Single vibronic level emission spectra were also recorded, resulting in the determination of all three HPS ground state vibrational frequencies. High level ab initio calculations were used to help confirm the vibronic assignments by calculation of transition energies, anharmonic vibrational frequencies, and anharmonic Franck- Condon factors. Ab initio potential energy surfaces gave an equilibrium structure for the (X) over tilde (1)A' state of r(PH)'' = 1.4334 angstrom, r(PS)'' = 1.9373 angstrom, 0 '' = 101.77 degrees and for the (A) over tilde (1)A '' state of r(PH)' = 1.4290 angstrom, r(PS)' = 2.0635 angstrom, and 0' = 91.74 degrees. The rotational contours observed are consistent with these structures, confirming that the bond angle of HPS decreases on electronic excitation. Although the bond angles of HNO and HNS open in the excited state, in accord with the Walsh predictions for 12 valence electron HAB molecules, HPO, HAsO and now HPS all show the opposite behavior.

Theory and Markov models SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID MOLECULAR-DYNAMICS; STATE MODELS; ALANINE DIPEPTIDE; METASTABLE STATES; ORIENTED ANALYSIS; FOLDING DYNAMICS; PROGRAM PACKAGE; SIMULATIONS; WATER; KINETICS AB The dynamics of complex molecules can be directly probed by inelastic neutron scattering experiments. However, many of the underlying dynamical processes may exist on similar timescales, which makes it difficult to assign processes seen experimentally to specific structural rearrangements. Here, we show how Markov models can be used to connect structural changes observed in molecular dynamics simulation directly to the relaxation processes probed by scattering experiments. For this, a conformational dynamics theory of dynamical neutron and X-ray scattering is developed, following our previous approach for computing dynamical fingerprints of time-correlation functions [F. Noe, S. Doose, I. Daidone, M. Lollmann, J. Chodera, M. Sauer, and J. Smith, Proc. Natl. Acad. Sci. U. S. A. 108, 4822 (2011)]. Markov modeling is used to approximate the relaxation processes and timescales of the molecule via the eigenvectors and eigenvalues of a transition matrix between conformational substates. This procedure allows the establishment of a complete set of exponential decay functions and a full decomposition into the individual contributions, i.e., the contribution of every atom and dynamical process to each experimental relaxation process.

TI Quantized Hamiltonian dynamics captures the low-temperature regime of charge transport in molecular crystals SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID MEAN-FIELD APPROXIMATION; SURFACE HOPPING APPROACH; ORGANIC SEMICONDUCTORS; ELECTRONIC TRANSPORT; KINETIC-THEORY; MOBILITY; TRANSISTORS; QUANTUM; NAPHTHALENE; MOTION AB The quantized Hamiltonian dynamics (QHD) theory provides a hierarchy of approximations to quantum dynamics in the Heisenberg representation. We apply the first-order QHD to study charge transport in molecular crystals and find that the obtained equations of motion coincide with the Ehrenfest theory, which is the most widely used mixed quantum-classical approach. Quantum initial conditions required for the QHD variables make the dynamics surpass Ehrenfest. Most importantly, the first-order QHD already captures the low-temperature regime of charge transport, as observed experimentally. We expect that simple extensions to higher-order QHDs can efficiently represent other quantum effects, such as phonon zero-point energy and loss of coherence in the electronic subsystem caused by phonons.

TI Dynamic neutron scattering from conformational dynamics. II. Application using molecular dynamics simulation and Markov modeling SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID STATE MODELS; KINETICS; FINGERPRINTS; MYOGLOBIN; PATHWAYS; REVEALS; SYSTEMS; WATER AB Neutron scattering experiments directly probe the dynamics of complex molecules on the sub pico- to microsecond time scales. However, the assignment of the relaxations seen experimentally to specific structural rearrangements is difficult, since many of the underlying dynamical processes may exist on similar timescales. In an accompanying article, we present a theoretical approach to the analysis of molecular dynamics simulations with a Markov State Model (MSM) that permits the direct identification of structural transitions leading to each contributing relaxation process. Here, we demonstrate the use of the method by applying it to the configurational dynamics of the well-characterized alanine dipeptide. A practical procedure for deriving the MSM from an MD is introduced. The result is a 9-state MSM in the space of the backbone dihedral angles and the side-chain methyl group. The agreement between the quasielastic spectrum calculated directly from the atomic trajectories and that derived from the Markov state model is excellent. The dependence on the wavevector of the individual Markov processes is described. The procedure means that it is now practicable to interpret quasielastic scattering spectra in terms of well-defined intramolecular transitions with minimal a priori assumptions as to the nature of the dynamics taking place.

J. Phys. Chem. A 1998, 102, 7787-7794) and its variants are currently considered one of the most reliable source of single-ion hydration thermodynamic data and have been used as a benchmark for the development of molecular and continuum solvation models. Despite its importance, the CPA has not been thoroughly tested and recent studies have indicated inconsistencies with molecular simulations. The present work challenges the key CPA assumptions that the hydration properties of single cations and anions in growing clusters rapidly converge to each other following a monotonous trend. Using a combination of simulation techniques to study the transition between alkali halide ions in small clusters and bulk solution, we show that this convergence is rather slow and involves a surprising change in trends, which can result in significant errors in the original estimated single-ion properties. When these cluster-size-dependent effects are taken into account, the inconsistencies between molecular models and experimental predictions disappear, and the value of the proton hydration enthalpy based on the CPA aligns with estimates based on other principles.

We demonstrate that X-ray fluorescence and reflectivity techniques provide a more direct measurement of surface adsorption. Furthermore, we show that for [C(12)mim][Cl] and [C(12)mim][I] solutions with mixed inorganic salts (NaI, NaCl), I- ions replace Cl- above the critical micelle concentration (CMC) of [C(12)mim][Cl] at much lower concentrations of NaI whereas NaCl concentrations a hundred times higher than the CMC of [C(12)mim][I] only partially replace the I- at the interface. Our surface-sensitive X-ray diffraction and spectroscopy provide two independent tools to directly determine the surface adsorption of ionic surfactants and the interfacial composition of the surface films.

During the solvent-assisted mixing and nanocomposite formation, a chemical reaction occurs in which the C-60 cages are significantly modified by polymerization as well as by hydrogenation (fullerane formation) in the presence of LiBH4. We have determined that two distinct hydrogen desorption events are observed upon rehydrogenation of the material, which are attributed to the reversible formation of a fullerane (C60Hx) as well as a LiBH4 species. This system is unique in that the carbon species (C-60) actively participates in the hydrogen storage process which differs from the common practice of melt infiltration of high surface area carbon materials with LiBH4 (nanoconfinement effect). This nanocomposite demonstrated reversible hydrogen storage properties as well as the ability to absorb hydrogen under mild conditions (pressures as low as 10 bar of H-2 or temperatures as low as 150 degrees C). The nanocomposite was characterized by TGA-RGA, DSC, XRD, LDI-TOF-MS, FT-IR, H-1 NMR, and APPI MS. C1 [Ward, Patrick A.; Compton, Robert N.] Univ Tennessee, Dept Chem, Knoxville, TN 37996 USA.

The results show that detectable concentrations of particles begin to form at solution temperatures above 130 degrees C, and both the size and volume of the particles increase with heating temperature and time. The radius of the particles detected ranges from 0.5 +/- 0.1 nm to a few nanometers, depending on the temperature and heating time. The structure of the particles was probed by measurement of pair distribution functions, which demonstrated that the particles have structure identical to bulk metallic Pd. The identification of the particles as metallic Pd was confirmed by X-ray absorption near-edge structure spectroscopy, and transmission electron microscopy.

We use a first-principles-based cluster expansion (CE) and Monte Carlo simulations. We predict the adsorption isotherm and cyclic voltammogram for -0.9 V < U < 0.5 V versus the standard hydrogen potential. Although strongly adsorbed H-fcc* are the majority species for U > 0, we show that traces of weakly adsorbed H*(atop) and H-hcp* are present, and they are expected to be active in the HER. For U < 0, we predict that H-atop* takes over as the majority species ca. U = -0.4 V, where a simultaneous decrease in H-fcc* occurs-contradicting the general assumption that H-fcc*, remains the majority species, even at very negative potential. We identify the favorable HER operating potentials by mapping out the coverage of the kinetically active species H-atop*.

Effect of Temperature and pH on the Adsorption and Dynamics of Ions SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID MOLECULAR-DYNAMICS; WATER INTERFACE; MUSIC MODEL; HYDRATION WATER; SIMULATIONS; CASSITERITE; METAL; PROTONATION; POTENTIALS; SOLVATION AB Adsorption of RB+, Na+, Sr2+, and Cl- on hydroxylated (110) rutile surfaces was studied by molecular dynamics (MD) simulations. Our previous work was extended to the range of surface charge densities from -0.2 to +0.1 C/m(2) (from -0.4 to +0.1 C/m(2) for Sr2+) and to temperatures of 25, 150, and 250 degrees C. These conditions can be linked to experimental surface charge and pH values from macroscopic titrations of rutile powders with surfaces dominated by 110 crystal planes. Simulations revealed that Na+ and Sr2+ adsorb closer to the surface, shifting from predominately bidentate to tetradentate inner sphere binding with increasing temperature, whereas Rb+ binding is predominately tetradentate at all temperatures. These differences are related to hydration energies, which must be partially overcome for inner-sphere binding and which decrease with increasing temperature and are lowest for Rb+ The interaction of Cl- with the rutile surface is generally less than that for cations because of repulsion by surface oxygen atoms.

Herein, we apply density functional theory (DFT) calculations to provide atomistic insights into the heterogeneous reaction between aqueous Fe(II) and the Fe-bearing clay mineral nontronite Fe2Si4O10(OH)(2) by studying its adsorption mechanism and interfacial Fe(II) Fe(III) electron transfer (ET) at edge and basal surfaces. We find that edge-bound Fe(II) adsorption complexes at different surface sites (ferrinol, silanol, and mixed) may coexist on both (010) and (110) edge facets, with complexes at ferrinol FeO(H) sites being the most energetically favorable and coupled to proton transfer. Calculation of the ET activation energy suggests that interfacial ET into dioctahedral Fe(III) sheets is probable at the clay edges and occurs predominantly but not exclusively through the complexes adsorbed at ferrinol sites and might also involve mixed sites. No clear evidence is found for complexes on basal surface that are compatible with ET through the basal sheet despite this experimentally hypothesized ET interface. This study suggests a strong pH-dependence of Fe(II) surface complexation at basal versus edge facets and highlights the importance of the protonation state of bridging ligands and proton coupled electron transfer to facilitate ET into Fe-rich clay minerals.

These electrons exist in polaronic states, residing at Ce3+ sites, which can be created by either the formation of oxygen vacancies, O-v, or other surface defects. Via ab initio molecular dynamics, these localized electrons are found to be able to move freely within the upper surface layer, but penetration into the bulk is inhibited as a result of the higher elastic strain induced by creating a subsurface Ce3+. We found that the water molecule can be easily dissociated into two surface bound hydroxyls at the Ce4+ site associated with O-v sites. This dissociation process does not significantly affect the electronic structure of the excess electrons at reduced surface, but does lead to a favorable localization on Ce3+ sites in the vicinity of the resulting OH groups. In the presence of water, a proton-mediated Mars-van Krevelen mechanism for CO oxidation via the formation of bicarbonate species is identified. The localized 4f electrons on the surface facilitate the protonation process of adsorbed O-2 species and thus decelerate the further oxidation of CO species. Overall, we find that surface hydroxyls formed via water dissociation at the CeO2 surface lead to inhabitation of the CO oxidation reaction. This is consistent with the experimental observation of requisite elevated temperatures, on the order of 600 K, for this reaction to occur.

In this paper we study the localized SPR process in Ag- or Ag/oxide-coated single-layer superaligned carbon nanotube (SACNT) films. Because of the unidirectional alignment of the carbon nanotubes in these films, the Raman signal is higher when the laser is polarized parallel to the aligned direction than when perpendicular to it. We investigated the polarization-dependent transmittance and Raman spectra for various Ag particle sizes and different oxide medium layers to study the localized SPR in these composite structures. These results systematically characterize the properties of SACNT film-based SERS substrates and clarify the origin of transmittance peaks.

We report on the generation yield and recombination kinetics of free charge carriers in photoexcited thin films of polymer-wrapped s-SWCNTs with and without an overlying electron-accepting C-60 layer, using time-resolved microwave photoconductivity (TRMC). Free carriers are generated in neat s-SWCNT films, even without an obvious driving force for exciton dissociation. However, most carriers recombine in <10 ns. Adding C-60 increases the yield and extends the lifetime of a significant fraction of free carriers to >> 100 ns via interfacial charge separation. Spectral dependencies indicate that the driving force for interfacial electron transfer large-diameter SWCNTs, from which we approximate (9,7) s-SWCNT energetics. We estimate a free carrier generation yield of similar to 6% in neat s-SWCNT films and 9 GHz SWCNT hole mobility of >1.3 cm(2) V-1 s(-1). These studies improve understanding of s-SWCNT photoresponses in solar cells and photodetectors.

First-principles density functional theory calculations lend support to previously-reported experimental data and the concept that a Li-Fe-O/Fe-O charge product derived electrochemically from a parent Li5FeO4 crystalline structure can react, at thermodynamic equilibrium, with lithium and oxygen at or above the potential for Li-O-2 reactions to regenerate the Li5FeO4 composition, presumably with concomitant redox of the iron ions to assist the catalytic process. Because all of the lithium, iron, and oxygen required for the electrochemical reaction are, in principle, contained in the parent Li5FeO4 structure, these results have exciting implications for designing an "all-in-one" electrode for a hybrid Li ion/Li-O-2 cell that can provide a specific energy and an energy density that far exceeds the practical energy of conventional lithium ion batteries.

However, the use of this method for studying dilute aqueous systems, such as metalloenzymes, has not been prevalent because of severe radiation damage and the lack of suitable detection systems. Here we present spectra from a dilute Mn aqueous solution using a high-transmission zone-plate spectrometer at the Linac Coherent Light Source (LCLS). The spectrometer has been optimized for discriminating the Mn L-edge signal from the overwhelming 0 K-edge background that arises from water and protein itself, and the ultrashort LCLS X-ray pulses can outrun X-ray induced damage. We show that the deviations of the partial-fluorescence yield-detected spectra from the true absorption can be well modeled using the state-dependence of the fluorescence yield, and discuss implications for the application of our concept to biological samples.

TI Femtosecond M-2,M-3-Edge Spectroscopy of Transition-Metal Oxides: Photoinduced Oxidation State Change in alpha-Fe2O3 SO JOURNAL OF PHYSICAL CHEMISTRY LETTERS LA English DT Article ID RAY-ABSORPTION SPECTROSCOPY; HEMATITE ALPHA-FE2O3; HARMONIC-GENERATION; STRUCTURAL DYNAMICS; SPECTRA; EDGE; NANOPARTICLES; COMPLEXES; ULTRAFAST; FIELD AB Oxidation-state-specific dynamics at the Fe M-2,M-3-edge are measured on the sub-100 fs time scale using tabletop high-harmonic extreme ultraviolet spectroscopy. Transient absorption spectroscopy of alpha-Fe2O3 thin films after 400 nm excitation reveals distinct changes in the shape and position of the 3p -> valence absorption peak at similar to 57 eV due to a ligand-to-metal charge transfer from 0 to Fe. Semiempirical ligand field multiplet calculations of the spectra of the initial Fe3+ and photoinduced Fe2+ state confirm this assignment and exclude the alternative d-d excitation. The Fe2+ state decays to a long-lived trap state in 240 fs. This work establishes the ability of time-resolved extreme ultraviolet spectroscopy to measure ultrafast charge-transfer processes in condensed-phase systems.

Surface characterization of the outermost surface layers by high-sensitivity low energy ion scattering (HS-LEIS) and high-resolution X-ray photoelectron spectroscopy (HR-XPS) revealed that the GaN support consists of a GaOx outermost surface layer on a thin film of GaOxNy. HR-XPS demonstrates that the supported (Rh2-yCryO3) mixed oxide nanoparticles (NPs) consist of Cr3+ and Rh3+ cations that are surface enriched for (Rh2-yCryO3)/ GaN. Raman and UV-vis spectroscopy show that the bulk molecular and electronic structures, respectively, of the GaN support are not perturbed by the deposition of the (Rh2-yCryO3) NPs. The function of the GaN bulk lattice is to generate photoexcited electrons/holes, with the electrons harnessed by the surface Rh3+ sites for evolution of H-2 and the holes trapped at the Ga oxide/oxynitride surface sites for splitting,of water and evolving O-2.

TI Spin-On Organic Polymer Dopants for Silicon SO JOURNAL OF PHYSICAL CHEMISTRY LETTERS LA English DT Article ID JUNCTION FORMATION; NANOWIRE ARRAYS; DIFFUSION; PHOSPHORUS; SIMULATION; DEVICES; BORON AB We introduce a new class of spin-on dopants composed of organic, dopant-containing polymers. These new dopants offer a hybrid between conventional inorganic spin-on dopants and a recently developed organic monolayer doping technique that affords unprecedented control and uniformity of doping profiles. We demonstrate the ability of polymer film doping to achieve both p-type and n-type silicon by using boron- and phosphorus-containing polymer films. Different doping mechanisms are observed for boron and phosphorus doping, which could be related to the specific chemistries of the polymers. Thus, there is an opportunity to further control doping in the future by tuning the polymer chemistry.

TI Formation of Iron Oxyfluoride Phase on the Surface of Nano-Fe3O4 Conversion Compound for Electrochemical Energy Storage SO JOURNAL OF PHYSICAL CHEMISTRY LETTERS LA English DT Article ID LITHIUM-ION BATTERIES; METAL FLUORIDE NANOCOMPOSITES; X-RAY-DIFFRACTION; SOLID-STATE NMR; ANODE MATERIAL; REACTION-MECHANISMS; ELECTRODE MATERIALS; NEGATIVE-ELECTRODE; XPS SPECTRA; ALPHA-FE2O3 AB We have investigated a novel approach wherein we undertake surface fluorination of nanometer sized Fe3O4 conversion compound into corresponding oxyfluoride with the goal toward enhancing their energy density as well electrochemical performance stability. This is achieved by using direct fluorination of nano-Fe3O4 in a fluidized bed reactor under controlled reaction atmosphere and temperature. X-ray photoemission spectroscopy analysis shows conclusive evidence of the surface fluorination of Fe3O4 particles at a reaction temperature of 100 degrees C and higher forming a surface oxyfluoride phase that can be nominally described as FeOF. Formation of oxyfluoride phase is confirmed by the appearance of a higher potential intercalation plateau during the electrochemical charge discharge cycling. Based on the experimental results, various pathways are discussed for the formation of oxyfluoride species on the surface.

TI Exploring the XPS limit in soft and hard x-ray angle-resolved photoemission using a temperature-dependent one-step theory SO PHYSICAL REVIEW B LA English DT Article ID BULK ELECTRONIC-STRUCTURE; PHOTOELECTRON-SPECTROSCOPY; ALLOYS; DIFFRACTION; MODEL AB We present a theory of temperature-dependent photoemission which accurately describes phonon effects in soft and hard x-ray angle-resolved photoemission. Our approach is based on a fully relativistic one-step theory of photoemission that quantitatively reproduces the effects of phonon-assisted transitions beyond the usual k-conserving dipole selection rules which lead to the so-called XPS limit in the hard x-ray and/or high temperature regime. Vibrational atomic displacements have been included using the coherent potential approximation in analogy to the treatment of disordered alloys. The applicability of this alloy analogy model is demonstrated by direct comparison to experimental soft x-ray data from W(110) showing very satisfying agreement.

The idea can be easily adapted to other branches of physics and computational science that employ Monte Carlo methods. The error reduction techniques, referred to as covariant approximation averaging, utilize approximations which are covariant under lattice symmetry transformations. We observe cost reductions from the new method compared to the traditional one, for fixed statistical error, of 16 times for the nucleon mass at M-pi similar to 330 MeV (domain-wall quark) and 2.6-20 times for the hadronic vacuum polarization at M-pi similar to 315 MeV (Asqtad quark). These cost reductions should improve with decreasing quark mass and increasing lattice sizes. C1 [Blum, Thomas] Univ Connecticut, Dept Phys, Storrs, CT 06269 USA.

TI Importance of non-parabolic band effects in the thermoelectric properties of semiconductors SO SCIENTIFIC REPORTS LA English DT Article ID SELENIDE; FIGURE; MERIT; PBTE; SNTE AB We present an analysis of the thermoelectric properties of of n-type GeTe and SnTe in relation to the lead chalcogenides PbTe and PbSe. We find that the singly degenerate conduction bands of semiconducting GeTe and SnTe are highly non-ellipsoidal, even very close to the band edges. This leads to isoenergy surfaces with a strongly corrugated shape that is clearly evident at carrier concentrations well below 0.005 e per formula unit (7-9 x 10(19) cm(-3) depending on material). Analysis within Boltzmann theory suggests that this corrugation may be favorable for the thermoelectric transport. Our calculations also indicate that values of the power factor for these two materials may well exceed those of PbTe and PbSe. As a result these materials may exhibit n-type performance exceeding that of the lead chalcogenides.

TI Minority-spin t(2g) states and the degree of spin polarization in ferromagnetic metallic La2-2xSr1+2xMn2O7 (x=0.38) SO SCIENTIFIC REPORTS LA English DT Article ID COLOSSAL MAGNETORESISTIVE OXIDES; ELECTRONIC-STRUCTURE; FERMI-SURFACE; MANGANITES; LASR2MN2O7; JUNCTIONS AB A half-metal is a material with conductive electrons of one spin orientation. This type of substance has been extensively searched for due to the fascinating physics as well as the potential applications for spintronics. Ferromagnetic manganites are considered to be good candidates, though there is no conclusive evidence for this notion. Here we show that the ferromagnet La2-2xSr1+2xMn2O7 (x = 0.38) possesses minority-spin states, challenging whether any of the manganites may be true half-metals. However, when electron transport properties are taken into account on the basis of the electronic band structure, we found that the La2-2xSr1+2xMn2O7 (x = 0.38) can essentially behave like a complete half metal.

TI Wound outcome in combat injuries is associated with a unique set of protein biomarkers SO JOURNAL OF TRANSLATIONAL MEDICINE LA English DT Article DE Traumatic wound; Proteomics; 2-D DIGE; Wound effluent; Biomarker discovery; Wound dehiscence ID ACTIVATED HUMAN PLATELETS; CELLULAR STRESS-RESPONSE; PROTEOMIC ANALYSIS; POSTTRANSLATIONAL MODIFICATIONS; LOWER-EXTREMITY; TISSUE-REPAIR; BLAST INJURY; PHOSPHORYLATION; C3; EXPRESSION AB Background: The ability to forecast whether a wound will heal after closure without further debridement(s), would provide substantial benefits to patients with severe extremity trauma. Methods: Wound effluent is a readily available material which can be collected without disturbing healthy tissue. For analysis of potential host response biomarkers, forty four serial combat wound effluent samples from 19 patients with either healing or failing traumatic-and other combat-related wounds were examined by 2-D DIGE. Spot map patterns were correlated to eventual wound outcome (healed or wound failure) and analyzed using DeCyder 7.0 and differential proteins identified via LC-MS/MS. Results: This approach identified 52 protein spots that were differentially expressed and thus represent candidate biomarkers for this clinical application. Many of these proteins are intimately involved in inflammatory and immune responses. Furthermore, discriminate analysis further refined the 52 differential protein spots to a smaller subset of which successfully differentiate between wounds that will heal and those that will fail and require further surgical intervention with greater than 83% accuracy. Conclusion: These results suggest candidates for a panel of protein biomarkers that may aid traumatic wound care prognosis and treatment. We recommend that this strategy be refined, and then externally validated, in future studies of traumatic wounds.

A logical extension of these models is to incorporate treatment regimens to investigate network responses to intervention. The addition of nascent neurons from stem cell precursors into damaged or diseased tissue has been used as a successful therapeutic tool in recent decades. Interestingly, models have been developed to examine the incorporation of new neurons into intact adult structures, particularly the dentate granule neurons of the hippocampus. These studies suggest that the unique properties of maturing neurons, can impact circuit behavior in unanticipated ways. In this perspective, we review the current status of models used to examine damaged CNS structures with particular focus on cortical damage due to stroke. Secondly, we suggest that computational modeling of cell replacement therapies can be made feasible by implementing approaches taken by current models of adult neurogenesis. The development of these models is critical for generating hypotheses regarding transplant therapies and improving outcomes by tailoring transplants to desired effects.

However, Fe also shows much lower reactivity than other metals (such as Ni and Cu). Here, we demonstrate strong improvement of Fe-based carriers by alloying the metal phase with Ni. Through a combination of carrier synthesis and characterization with thermogravimetric and fixed-bed reactor studies, we demonstrate that the addition of Ni results in a significant enhancement in activity as well as an increase in selectivity for total oxidation. Furthermore, comparing alumina and ceria as support materials highlights the fact that reducible supports can result in a strong increase in oxygen carrier utilization.

Specifically, we studied the sorption of iodine gas in zeolitic imidazolate framework-8 (ZIF-8, Zn(2-methyl-imidazolate)(2)). Two iodine-loaded ZIF-8 samples were examined. The first, before thermal treatment, contained 0.17 I-2/Zn on the surface and 0.59 I-2/Zn inside the cage. The second sample was thermally treated, leaving only cage-confined iodine, 0.59 I-2/Zn. The energetics of iodine confinement per I-2 (relative to solid I-2) in ZIF-8 are Delta H-ads = -41.47 +/- 2.03 kJ/(mol I-2) within the cage and Delta H-ads = -18.06 +/- 0.62 kJ/(mol I-2) for surface bound iodine. The cage-confined iodine exhibits a 3-fold increase in binding energy over CT complexes on various organic adsorbents, which show only moderate exothermic heats of binding, from -5 to -15 kJ/(mol I-2). The ZIF-8 cage geometry allows each iodine atom to form two CT complexes between opposing 2-methylimidazolate linkers, creating the ideal binding site to maximize iodine retention.

Films thicker than 2 angstrom engender an exponential decrease in ET time with increasing film thickness, consistent with tunneling theory. Increasing the height of the barrier, as measured by the energy difference between the transferring electron and the bottom of the conduction band of the barrier material, results in steeper exponential drops in tunneling rate or probability. The variations are quantitatively consistent with a simple model of quantum tunneling of electrons through square barriers (i.e., barriers of individually uniform energy height) that are characterized by individually uniform physical thickness. The findings demonstrate that ALD is a remarkably uniform and precise method for modifying electrode surfaces and imply that standard tunneling theory can be used as a quantitative guide to intentionally and predictively modulating rates of ET between molecules and electrodes.

TI Single-Crystal Structure of a Covalent Organic Framework SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID AUTOMATED DIFFRACTION TOMOGRAPHY; NETWORKS; CRYSTALLOGRAPHY; NETS AB The crystal structure of a new covalent organic framework, termed COF-320, is determined by single-crystal 3D electron diffraction using the rotation electron diffraction (RED) method for data collection. The COF crystals are prepared by an imine condensation of tetra-(4-anilyl)methane and 4,4'-biphenyldialdehyde in 1,4-dioxane at 120 degrees C to produce a highly porous 9-fold interwoven diamond net. COF-320 exhibits permanent porosity with a Langmuir surface area of 2400 m(2)/g and a methane total uptake of 15.0 wt % (176 cm(3)/cm(3)) at 25 degrees C and 80 bar. The successful determination of the structure of COF-320 directly from single-crystal samples is an important advance in the development of COF chemistry.

TI Stepwise Protonation and Electron-Transfer Reduction of a Primary Copper-Dioxygen Adduct SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID ALPHA-HYDROXYLATING MONOOXYGENASE; DOPAMINE BETA-MONOOXYGENASE; O BOND-CLEAVAGE; END-ON; SUPEROXO COMPLEX; ACTIVE-SITE; MONONUCLEAR COPPER; OXYGEN ACTIVATION; POLYSACCHARIDE MONOOXYGENASES; MULTICOPPER OXIDASES AB The protonation-reduction of a dioxygen adduct with [LCuI][B(C6F5)(4)], cupric superoxo complex [LCuII(O-2(center dot-))] (1) (L = TMG(3)tren (1,1,1-tris[2-[N-2-(1,1,3,3-tetramethylguanidino)]ethyl]amine)) has been investigated. Trifluoroacetic acid (HOAcF) reversibly associates with the superoxo ligand in ([LCuII(O-2(center dot-))](+)) in a 1:1 adduct [LCuII(O-2(center dot-))(HOAcF)](+) (2), as characterized by UV-visible, resonance Raman (rR), nuclear magnetic resonance (NMR), and X-ray absorption (XAS) spectroscopies, along with density functional theory (DFT) calculations. Chemical studies reveal that for the binding of HOAcF with 1 to give 2, K-eq = 1.2 x 10(5) M-1 (-130 degrees C) and Delta H degrees = -6.9(7) kcal/mol, Delta S degrees = -26(4) cal mol(-1) K-1). Vibrational (rR) data reveal a significant increase (29 cm(-1)) in v(o-o) (= 1149 cm(-1)) compared to that known for [LCuII(O-2(center dot-))](+) (1). Along with results obtained from XAS and DFT calculations, hydrogen bonding of HOAcF to a superoxo O-atom in 2 is established. Results from NMR spectroscopy of 2 at -120 degrees C in 2-methyltetrahydrofuran are also consistent with 1/HOAcF = 1:1 formulation of 2 and with this complex possessing a triplet (S = 1) ground state electronic configuration, as previously determined for 1. The pre-equilibrium acid association to 1 is followed by outer-sphere electron-transfer reduction of 2 by decamethylferrocene (Me(10)Fc) or octamethylferrocene (Me(8)Fc), leading to the products H2O2, the corresponding ferrocenium salt, and [LCuII(OAcF)](+). Second-order rate constants for electron transfer (k(et)) were determined to be 1365 M-1 s(-1) (Me(10)Fc) and 225 M-1 s(-1) (Me(8)Fc) at -80 degrees C. The (bio)chemical relevance of the proton-triggered reduction of the metal-bound dioxygen-derived fragment is discussed.

TI Enhanced CO Oxidation Rates at the Interface of Mesoporous Oxides and Pt Nanoparticles SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID METAL-SUPPORT INTERACTIONS; PLATINUM NANOPARTICLES; CATALYTIC-ACTIVITY; CARBON-MONOXIDE; TITANIUM-OXIDE; COBALT OXIDE; NOBLE-METALS; TEMPERATURE; OXYGEN; CO3O4 AB The interaction of the metal and support in oxide-supported transition-metal catalysts has been proven to have extremely favorable effects on catalytic performance. Herein, mesoporous Co3O4, NiO, MnO2, Fe2O3, and CeO2 were synthesized and utilized in CO oxidation reactions to compare the catalytic activities before and after loading of 2.5 nm Pt nanoparticles. Turnover frequencies (TOFs) of pure mesoporous oxides were 0.0002-0.015 s(-1), while mesoporous silica was catalytically inactive in CO oxidation. When Pt nanoparticles were loaded onto the oxides, the TOFs of the Pt/metal oxide systems (0.1-500 s(-1)) were orders of magnitude greater than those of the pure oxides or the silica-supported Pt nanoparticles. The catalytic activities of various Pt/oxide systems were further influenced by varying the ratio of CO and O-2 in the reactant gas feed, which provided insight into the mechanism of the observed support effect. In situ characterization using near-edge X-ray absorption fine structure (NEXAFS) and ambient-pressure X-ray photoelectron spectroscopy (APXPS) under catalytically relevant reaction conditions demonstrated a strong correlation between the oxidation state of the oxide support and the catalytic activity at the oxide-metal interface. Through catalytic activity measurements and in situ X-ray spectroscopic probes, CoO, Mn3O4, and CeO2 have been identified as the active surface phases of the oxide at the interface with Pt nanoparticles.

TI Ecosystem-Service Tradeoffs Associated with Switching from Annual to Perennial Energy Crops in Riparian Zones of the US Midwest SO PLOS ONE LA English DT Article ID LAND-USE; AGRICULTURAL LANDSCAPES; MISSISSIPPI RIVER; BIODIVERSITY; BIOENERGY; ETHANOL; CARBON; CORN; CONSERVATION; DIVERSITY AB Integration of energy crops into agricultural landscapes could promote sustainability if they are placed in ways that foster multiple ecosystem services and mitigate ecosystem disservices from existing crops. We conducted a modeling study to investigate how replacing annual energy crops with perennial energy crops along Wisconsin waterways could affect a variety of provisioning and regulating ecosystem services. We found that a switch from continuous corn production to perennial-grass production decreased annual income provisioning by 75%, although it increased annual energy provisioning by 33%, decreased annual phosphorous loading to surface water by 29%, increased below-ground carbon sequestration by 30%, decreased annual nitrous oxide emissions by 84%, increased an index of pollinator abundance by an average of 11%, and increased an index of biocontrol potential by an average of 6%. We expressed the tradeoffs between income provisioning and other ecosystem services as benefit-cost ratios. Benefit-cost ratios averaged 12.06 GJ of additional net energy, 0.84 kg of avoided phosphorus pollution, 18.97 Mg of sequestered carbon, and 1.99 kg of avoided nitrous oxide emissions for every $ 1,000 reduction in income. These ratios varied spatially, from 2- to 70-fold depending on the ecosystem service. Benefit-cost ratios for different ecosystem services were generally correlated within watersheds, suggesting the presence of hotspots - watersheds where increases in multiple ecosystem services would come at lower-than-average opportunity costs. When assessing the monetary value of ecosystem services relative to existing conservation programs and environmental markets, the overall value of enhanced services associated with adoption of perennial energy crops was far lower than the opportunity cost. However, when we monitized services using estimates for the social costs of pollution, the value of enhanced services far exceeded the opportunity cost. This disparity between recoverable costs and social value represents a fundamental challenge to expansion of perennial energy crops and sustainable agricultural landscapes.

TI X-ray emission measurements following charge exchange between C6+ and He SO PHYSICAL REVIEW A LA English DT Article ID BUBBLE HOT GAS; SOLAR-WIND; ELECTRON-CAPTURE; CROSS-SECTIONS; ULTRAVIOLET EMISSION; SLOW COLLISIONS; PROJECTILES; INFERENCES AB X-ray spectra following charge-exchange collisions between C6+ and He are presented for collision energies between 460 and 32 000 eV/u. Spectra were obtained at the Oak Ridge National Laboratory Multicharged Ion Research Facility using a microcalorimeter x-ray detector capable of fully resolving the C VI Lyman series lines through Ly-gamma. These line ratios are sensitive to the initial electron l distribution and test our understanding of the charge-exchange process. In addition, these line ratios are important for identifying charge exchange in astrophysical contexts involving the interaction of solar wind ions with neutrals. Our measurements are performed at collision velocities (300-2500 km/s) which overlap most of the solar wind range. Additional data of this type can be combined with computations to provide an extensive set of reliable line ratios and absolute cross sections for the interpretation of a variety of astrophysical situations.

Microarrays of sequences within protein-encoding genes were probed with RNA purified from extracts of vegetative cells, from isolated heterocysts, and from whole filaments to investigate transcript levels, and carbon and energy metabolism, in vegetative cells and heterocysts in phototrophic, mixotrophic, and heterotrophic cultures. Results: Heterocysts represent only 5% to 10% of cells in the filaments. Accordingly, levels of specific transcripts in vegetative cells were with few exceptions very close to those in whole filaments and, also with few exceptions (e. g., nif1 transcripts), levels of specific transcripts in heterocysts had little effect on the overall level of those transcripts in filaments. In phototrophic, mixotrophic, and heterotrophic growth conditions, respectively, 845, 649, and 846 genes showed more than 2-fold difference (p < 0.01) in transcript levels between vegetative cells and heterocysts. Principal component analysis showed that the culture conditions tested affected transcript patterns strongly in vegetative cells but much less in heterocysts. Transcript levels of the genes involved in phycobilisome assembly, photosynthesis, and CO2 assimilation were high in vegetative cells in phototrophic conditions, and decreased when fructose was provided. Our results suggest that Gln, Glu, Ser, Gly, Cys, Thr, and Pro can be actively produced in heterocysts. Whether other protein amino acids are synthesized in heterocysts is unclear. Two possible components of a sucrose transporter were identified that were upregulated in heterocysts in two growth conditions. We consider it likely that genes with unknown function represent a larger fraction of total transcripts in heterocysts than in vegetative cells across growth conditions. Conclusions: This study provides the first comparison of transcript levels in heterocysts and vegetative cells from heterocyst-bearing filaments of Anabaena. Although the data presented do not give a complete picture of metabolism in either type of cell, they provide a metabolic scaffold on which to build future analyses of cell-specific processes and of the interactions of the two types of cells.

We present coherent neutron scattering studies of the low-frequency vibrations, the so-called boson peak, in fully deuterated green fluorescent protein (GFP). Our analysis revealed unexpectedly low coherence of the atomic motions in GFP. This result implies a low amount of in-phase collective motion of the secondary structural units contributing to the boson peak vibrations and fast conformational fluctuations on the picosecond timescale. These observations are in contrast to earlier studies of polymers and glass-forming systems, and suggest that random or out-of-phase motions of the beta-strands contribute greater than two-thirds of the intensity to the low-frequency vibrational spectra of GFP.

TI Improved Crystallographic Structures Using Extensive Combinatorial Refinement SO STRUCTURE LA English DT Article ID X-RAY CRYSTALLOGRAPHY; PROTEIN DATA-BANK; FREE R-VALUE; MOLECULAR-REPLACEMENT; DIFFRACTION DATA; VALIDATION; DENSITY; MODELS; PHENIX; HETEROGENEITY AB Identifying errors and alternate conformers and modeling multiple main-chain conformers in poorly ordered regions are overarching problems in crystallographic structure determination that have limited automation efforts and structure quality. Here, we show that implementation of a full factorial designed set of standard refinement approaches, termed ExCoR (Extensive Combinatorial Refinement), significantly improves structural models compared to the traditional linear tree approach, in which individual algorithms are tested linearly and are only incorporated if the model improves. ExCoR markedly improved maps and models and reveals building errors and alternate conformations that were masked by traditional refinement approaches. Surprisingly, an individual algorithm that renders a model worse in isolation could still be necessary to produce the best overall model, suggesting that model distortion allows escape from local minima of optimization target function, here shown to be a hallmark limitation of the traditional approach. ExCoR thus provides a simple approach to improving structure determination. C1 [Nwachukwu, Jerome C.; Southern, Mark R.; Nettles, Kendall W.] Scripps Res Inst, Dept Canc Biol, Jupiter, FL 33458 USA.

TI Laser Ablation Sampling of Materials Directly into the Formed Liquid Microjunction of a Continuous Flow Surface Sampling Probe/Electrospray Ionization Emitter for Mass Spectral Analysis and Imaging SO ANALYTICAL CHEMISTRY LA English DT Article ID THIN-LAYER-CHROMATOGRAPHY; ELECTROSPRAY-IONIZATION; ATMOSPHERIC-PRESSURE; SPECTROMETRY; POLYANILINE; PROBE; MECHANISMS; PROTEINS; ONLINE; FILMS AB Transmission geometry laser ablation directly into a formed liquid microjunction of a continuous flow liquid microjunction surface sampling probe/electrospray ionization emitter was utilized for molecular and elemental detection and mass spectrometry imaging. The ability to efficiently capture and ionize ablated material was demonstrated by the detection of various small soluble n-mers of polyaniline and silver ion solvent clusters formed from laser ablation of electropolymerized polyaniline and silver thin films, respectively. In addition, analysis of surfaces that contain soluble components was accomplished by coating or laminating the sample with an insoluble film to enable liquid junction formation without directly extracting material from the surface. The ability to perform mass spectrometry imaging at a spatial resolution of about 50 mu m was illustrated by using laminated inked patterns on a microscope slide. In general, these data demonstrate at least an order of magnitude signal enhancement compared to the noncontact, laser ablation droplet capture-based surface sampling/ionization approaches that have been previously presented.

TI OpenMSI: A High-Performance Web-Based Platform for Mass Spectrometry Imaging SO ANALYTICAL CHEMISTRY LA English DT Article ID ASSISTED-LASER-DESORPTION/IONIZATION; SEGMENTATION; TISSUES; SAMPLES; TOOL; MSI AB Mass spectrometry imaging (MSI) enables researchers to directly probe endogenous molecules directly within the architecture of the biological matrix. Unfortunately, efficient access, management, and analysis of the data generated by MSI approaches remain major challenges to this rapidly developing field. Despite the availability of numerous dedicated file formats and software packages, it is a widely held viewpoint that the biggest challenge is simply opening, sharing, and analyzing a file without loss of information. Here we present OpenMSI, a software framework and platform that addresses these challenges via an advanced, high-performance, extensible file format and Web API for remote data access (http://openmsi.nersc.gov). The OpenMSI file format supports storage of raw MSI data, metadata, and derived analyses in a single, self-describing format based on HDF5 and is supported by a large range of analysis software (e.g., Matlab and R) and programming languages (e.g., C++, Fortran, and Python). Careful optimization of the storage layout of MSI data sets using chunking, compression, and data replication accelerates common, selective data access operations while minimizing data storage requirements and are critical enablers of rapid data I/O. The OpenMSI file format has shown to provide >2000-fold improvement for image access operations, enabling spectrum and image retrieval in less than 0.3 s across the Internet even for 50 GB MSI data sets. To make remote high-performance compute resources accessible for analysis and to facilitate data sharing and collaboration, we describe an easy-to-use yet powerful Web API, enabling fast and convenient access to MSI data, metadata, and derived analysis results stored remotely to facilitate high-performance data analysis and enable implementation of Web based data sharing, visualization, and analysis.

However, there is a lack of methodologies that allow the direct investigation of chemical gradients and interactions in living biological systems, in real time. Here, we report the use of nanospray desorption electrospray ionization (nanoDESI) imaging mass spectrometry for in vivo metabolic profiling of living bacterial colonies directly from the Petri dish with absolutely no sample preparation needed. Using this technique, we investigated single colonies of Shewanella oneidensis MR-1, Bacillus subtilis 3610, and Streptomyces coelicolor A3(2) as well as a mixed biofilm of S. oneidensis MR-1 and B. subtilis 3610. Data from B. subtilis 3610 and S. coelicolor A3(2) provided a means of validation for the method while data from S. oneidensis MR-1 and the mixed biofilm showed a wide range of compounds that this bacterium uses for the dissimilatory reduction of extracellular metal oxides, including riboflavin, iron-bound heme and heme biosynthetic intermediates, and the siderophore putrebactin.

The MNP-Che separation process is an effective way of separating heat generating minor actinides (Np, Am, Cm) from spent nuclear fuel solution to reduce the radiological hazard. It utilizes coated MNPs to selectively adsorb the contaminants onto their surfaces, after which the loaded particles are collected using a magnetic field. The MNP-Che conjugates can be recycled by stripping contaminates into a separate, smaller volume of solution, and then become the final waste form for disposal after reusing number of times. Due to the highly selective chelators, this remediation method could be both simple and versatile while allowing the valuable actinides to be recovered and recycled. Key issues standing in the way of large-scale application are stability of the conjugates and their dispersion in solution to maintain their unique properties, especially large surface area, of MNPs. With substantial research progress made on MNPs and their surface functionalization, as well as development of environmentally benign chelators, this method could become very flexible and cost-effective for recycling used fuel. Finally, the development of this nanotechnology is summarized and its future direction is discussed. C1 [Kaur, Maninder; Qiang, You] Univ Idaho, Dept Phys, Moscow, ID 83844 USA.

Such coatings are expected to affect metal ion sorption due to abundant sorption sites in NOM and potential modifications to mineral surfaces, but such effects are poorly understood in complex multicomponent systems. Using poly(acrylic acid) (PAA), a simplified analog of NOM containing only carboxylic groups, Pb(II) and Zn(II) partitioning between PAA coatings and alpha-Al2O3 (1-102) and (0001) surfaces was investigated using long-period X-ray standing wave-florescence yield spectroscopy. In the single-metal ion systems, PAA was the dominant sink for Pb(II) and Zn(II) for alpha-Al2O3(1-102) (63% and 69%, respectively, at 0.5 mu M metal ions and pH 6.0). In equi-molar mixed-Pb(II) Zn(II) systems, partitioning of both ions onto alpha-Al2O3(1-102) decreased compared with the single-metal ion systems; however, Zn(II) decreased Pb(II) sorption to a greater extent than vice versa, suggesting that Zn(II) outcompeted Pb(II) for alpha-Al2O3(1 102) sorption sites. In contrast, >99% of both metal ions sorbed to PAA when equi-molar Pb(II) and Zn(II) were added simultaneously to PAA/alpha-Al2O3(0001). PAA outcompeted both alpha-Al2O3 surfaces for metal sorption but did not alter their intrinsic order of reactivity. This study suggests that single-metal ion sorption results cannot be used to predict multimetal ion sorption at NOM/metal-oxide interfaces when NOM is dominated by carboxylic groups.

The availability of reliable long-term climatic field data at this site offers a unique opportunity to test the skill of mesoscale meteorological models describing and predicting the impacts of land use change on local climate. Using the Weather Research and Forecast (WRF) mesoscale model, we have run a sensitivity experiment to simulate the impact of the observed surface albedo change on monthly and annual surface air temperatures. The model output showed a mean annual cooling of 0.25 degrees C associated with a 0.09 albedo increase, and a reduction of 22.8 W m(-2) of net incoming solar radiation at surface. Mean reduction of summer daily maximum temperatures was 0.49 degrees C, with the largest single-day decrease equal to 1.3 degrees C. WRF output was evaluated and compared with observations. A mean annual warm bias (MBE) of 0.42 degrees C was estimated. High correlation coefficients (R-2 > 0.9) were found between modeled and observed values. This study has particular interest in the assessment of the potential for urban temperature cooling by cool roofs deployment projects, as well as in the evaluation of mesoscale climatic models performance.

Although previous studies that have quantified dynamic isotopic shifts during the reductive dechlorination of trichloroethene (TCE) indicate that fractionation factors can be highly variable from culture-to-culture and site-to-site, the effects of growth condition on the isotope fractionation during reductive dechlorination have not been previously examined. Here, carbon isotope fractionation by Dehalococcoides mccartyi 195 (Dhc195) maintained under a variety of growth conditions was examined. Enrichment factors quantified when Dhc195 was subjected to four suboptimal growth conditions, including decreased temperature (-13.3 +/- 0.9 parts per thousand), trace vitamin B-12 availability (-12.7 +/- 1.0 parts per thousand), limited fixed nitrogen (-14.4 +/- 0.8 parts per thousand), and elevated vinyl chloride exposure (-12.5 +/- 0.4 parts per thousand), indicate that the fractionation is similar across a range of tested conditions. The TCE enrichment factors for two syntrophic cocultures, Dhc195 with Desulfovibrio vulgaris Hildenborough (-13.0 +/- 2.0 parts per thousand) and Dhc195 with Syntrophomonas wolfei (-10.4 +/- 1.2 parts per thousand and 13.3 +/- 1.0 parts per thousand), were also similar to a control experiment. In order to test the stability of enrichment factors in microbial communities, the isotope fractionation was quantified for Dhc-containing groundwater communities before and after two-year enrichment periods under different growth conditions. Although these enrichment factors (-8.9 +/- 0.4 parts per thousand, 6.8 +/- 0.8 parts per thousand, 8.7 +/- 1.3 parts per thousand, 9.4 +/- 0.7 parts per thousand, and 7.2 +/- 0.3 parts per thousand) were predominantly outside the range of values quantified for the isolate and cocultures, all tested enrichment conditions within the communities produced nearly similar fractionations. Enrichment factors were not significantly affected by changes in any of the tested growth conditions for the pure cultures, cocultures or the mixed communities, indicating that despite a variety of temperature, nutrient, and cofactor-limiting conditions, stable carbon isotope fractionations remain consistent for given Dehalococcoides cultures.

CA ATLAS Collaboration TI Measurement of the top quark charge in pp collisions at root s=7 TeV with the ATLAS detector SO JOURNAL OF HIGH ENERGY PHYSICS LA English DT Article DE Hadron-Hadron Scattering; Top physics ID JETS AB A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb(-1) of data at a centre-of-mass energy of 7TeV. In units of the elementary electric charge, the top quark charge is determined to be 0.64 +/- 0.02 (stat.) +/- 0.08 (syst.) from the charges of the top quark decay products in single lepton t (t) over bar candidate events. This excludes models that propose a heavy quark of electric charge -4/3, instead of the Standard Model top quark, with a significance of more than 8 sigma.

TI Effects of Nanoscale Surface Texture and Lubricant Molecular Structure on Boundary Lubrication in Liquid SO LANGMUIR LA English DT Article ID DYNAMICS SIMULATION; PHASE-TRANSITIONS; CARBON DLC; TRIBOLOGICAL PERFORMANCE; SOLVATION FORCES; CONFINED FLUIDS; FRICTION; BEHAVIOR; FILMS; COATINGS AB Nanoconfinement effects of boundary lubricants can significantly affect the friction behavior of textured solid interfaces. These effects were studied with nanotextured diamond-like carbon (DLC) surfaces using a reciprocating ball-on-flat tribometer in liquid lubricants with different molecular structures: n-hexadecane and n-pentanol for linear molecular structure and poly(alpha-olefin) and heptamethylnonane for branched molecular structure. It is well-known that liquid lubricants with linear molecular structures can readily form a long-range ordered structure upon nanoconfinement between flat solid surfaces. This long-range ordering, often called solidification, causes high friction in the boundary lubrication regime. When the solid surface deforms elastically due to the contact pressure and this deformation depth is larger than the surface roughness, even rough surfaces can exhibit the nanoconfinement effects. However, the liquid entrapped in the depressed region of the nanotextured surface would not solidify, which effectively reduces the solidified lubricant area in the contact region and decreases friction. When liquid lubricants are branched, the nanoconfinement-induced solidification does not occur because the molecular structure is not suitable for the long-range ordering. Surface texture, therefore, has an insignificant effect on the boundary lubrication of branched molecules.

CA D0 Collaboration TI Studies of W boson plus jets production in p(p)over-bar collisions at root s=1.96 TeV SO PHYSICAL REVIEW D LA English DT Article ID PARTON DISTRIBUTIONS; EVENT GENERATOR; DETECTOR; LHC; NUCLEON AB We present a comprehensive analysis of inclusive W(-> ev) + n-jet (n >= 1, 2, 3, 4) production in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV at the Tevatron collider using a 3.7 fb(-1) data set collected by the D0 detector. Differential cross sections are presented as a function of the jet rapidities (y), lepton transverse momentum (P-T) and pseudorapidity (eta), the scalar sum of the transverse energies of the W boson and all jets (H-T), leading dijet P-T and invariant mass, dijet rapidity separations for a variety of jet pairings for P-T-ordered and angular-ordered jets, dijet opening angle, dijet azimuthal angular separations for P-T-ordered and angular-ordered jets, and W boson transverse momentum. The mean number of jets in an event containing a W boson is measured as a function of H-T, and as a function of the rapidity separations between the two highest-P-T jets and between the most widely separated jets in rapidity. Finally, the probability for third-jet emission in events containing a W boson and at least two jets is studied by measuring the fraction of events in the inclusive W + 2-jet sample that contain a third jet over a P-T threshold. The analysis employs a regularized singular value decomposition technique to accurately correct for detector effects and for the presence of backgrounds. The corrected data are compared to particle level next-to-leading-order perturbative QCD predictions, predictions from all-order resummation approaches, and a variety of leading-order and matrix element plus parton shower event generators. Regions of the phase space where there is agreement or disagreement with the data are discussed for the different models tested. C1 [Maciel, A. K. A.; Rangel, M. S.; Santos, A.

Liu, Tao Low, Ian Mintun, Eric TI Unraveling the physics behind modified Higgs couplings: LHC versus a Higgs factory SO PHYSICAL REVIEW D LA English DT Article ID STANDARD MODEL; BOSON; SEARCH AB Strongly modified h gamma gamma and hgg couplings indicate new electroweak and color mediators, respectively, with a light mass and a significant coupling to the Higgs boson. We point out the Higgs boson could have a significant decay width into the mediators. This represents one new class of exotic Higgs decay possibilities: off-shell exotic Higgs decays. We then propose uncovering the hidden new physics through such exotic decays. A great advantage of this strategy is that we can directly probe the couplings between the Higgs boson and the mediators, which is hard to achieve by using other methods. Focusing on the electroweak mediators, we study a simplified model using as an example final states with tau leptons and neutrinos. Because one of the mediators is off shell and its decay products are extremely soft, it is challenging to make a discovery at the Large Hadron Collider. A Higgs factory such as the International Linear Collider, however, could serve as a discovery machine for such exotic Higgs decays even in an early stage.

We introduce a quantum mechanics/molecular mechanics (QM/MM) model of the S-0 state that is consistent with extended X-ray absorption fine structure spectroscopy and X-ray diffraction data. In conjunction with the QM/MM model of the S-1 state, we address the proton-coupled electron-transfer (PCET) process that occurs during the S-0 -> S-1 transition, where oxidation of a Mn center and deprotonation of a mu-oxo bridge lead to a significant rearrangement in the OEC. A hydrogen bonding network, linking the D1-D61 residue to a Mn-bound water molecule, is proposed to facilitate the PCET mechanism. C1 [Pal, Rhitankar; Negre, Christian F.

These layers had a well-defined porous structure with a globular morphology demonstrated with SEM images and exhibited superhydrophobic properties characterized with a water contact angle of 157 degrees. They were then used for thin-layer chromatography of peptides and proteins fluorescently labeled with fluorescamine. The spots of individual separated compounds were visualized using UV light, and their identities were confirmed with a matrix-assisted laser desorption/ionization time of flight mass spectrometry. The presence of chloromethylstyrene units in the polymer enabled hypercrosslinking via a Friedel-Crafts alkylation reaction, and led to monoliths with much larger surface areas, which were suitable for separations of small dye molecules.

TI Gigantic magnetic-field-induced polarization and magnetoelectric coupling in a ferrimagnetic oxide CaBaCo4O7 SO PHYSICAL REVIEW B LA English DT Article ID FERROELECTRIC POLARIZATION; BORACITE AB Below TC, the single-crystal study of CaBaCo4O7, a noncollinear ferrimagnet (T-C = 64 K) with a polar orthorhombic space group (Pbn2(1)) between 4 and 293 K, shows a large change in the electric polarization along its (c) over right arrow axis reaching Delta P = 17 mC/m(2) at 10 K. At 62.5 K, a magnetic-field-driven giant variation in polarization P(9 T) - P(0 T) = 8 mC/m(2) is observed. Moreover, the present magnetoelectric measurements are fully consistent with the m'm2' magnetic point group. This ferrimagnetic oxide, which belongs to the "114" structural family, opens an avenue for the search for new magnetoelectrics.

TI Hamiltonian Mechanics of Stochastic Acceleration SO PHYSICAL REVIEW LETTERS LA English DT Article ID VARIATIONAL INTEGRATORS; TURBULENCE; DIFFUSION; EQUATIONS; ELECTRONS; PROTONS; SYSTEMS; WAVE AB We show how to find the physical Langevin equation describing the trajectories of particles undergoing collisionless stochastic acceleration. These stochastic differential equations retain not only one-, but two-particle statistics, and inherit the Hamiltonian nature of the underlying microscopic equations. This opens the door to using stochastic variational integrators to perform simulations of stochastic interactions such as Fermi acceleration. We illustrate the theory by applying it to two example problems. C1 [Burby, J. W.; Qin, H.] Princeton Plasma Phys Lab, Princeton, NJ 08543 USA. [Zhmoginov, A.

A surprising result revealed by our study is the presence of a clear signature of the transition at zero temperature and that this signature can be observed if and only if the spin-orbit coupling is taken into account. Our calculations indicate that the transition line in the pressure-temperature phase diagram of this material has a low-T critical point at negative pressures, placed very close to zero temperature. This suggests that cerium is very close to being "quantum critical," in agreement with recent experiments.

CA CMS Collaboration TI Search for a non-standard-model Higgs boson decaying to a pair of new light bosons in four-muon final states SO PHYSICS LETTERS B LA English DT Article DE LHC; CMS; Higgs; Supersymmetry; NMSSM; Muons ID SUPERSYMMETRIC MODELS; GAUGE-THEORIES; OPAL DETECTOR; SUPERGRAVITY; MASS; PARTICLE; LHC; EXTENSION; BREAKING; SINGLET AB Results are reported from a search for non-standard-model Higgs boson decays to pairs of new light bosons, each of which decays into the mu(+)mu(-) final state. The new bosons may be produced either promptly or via a decay chain. The data set corresponds to an integrated luminosity of 5.3 fb(-1) of proton-proton collisions at root s = 7 TeV, recorded by the CMS experiment at the LHC in 2011. Such Higgs boson decays are predicted in several scenarios of new physics, including supersymmetric models with extended Higgs sectors or hidden valleys. Thus, the results of the search are relevant for establishing whether the new particle observed in Higgs boson searches at the LHC has the properties expected for a standard model Higgs boson. No excess of events is observed with respect to the yields expected from standard model processes. A model-independent upper limit of 0.86 +/- 0.06 fb on the product of the cross section times branching fraction times acceptance is obtained. The results, which are applicable to a broad spectrum of new physics scenarios, are compared with the predictions of two benchmark models as functions of a Higgs boson mass larger than 86 GeV/c(2) and of a new light boson mass within the range 0.25-3.55 GeV/c(2).

CA ALICE Collaboration TI Centrality dependence of the pseudorapidity density distribution for charged particles in Pb-Pb collisions at root s(NN)=2.76 TeV SO PHYSICS LETTERS B LA English DT Article DE LHC; Heavy-ion collisions; Charged-particle density; Wide rapidity coverage ID QUARK-GLUON PLASMA; COLLABORATION; MULTIPLICITY; PERSPECTIVE; MODEL AB We present the first wide-range measurement of the charged-particle pseudorapidity density distribution, for different centralities (the 0-5%, 5-10%, 10-20%, and 20-30% most central events) in Pb-Pb collisions at root s(NN) = 2.76 TeV at the LHC. The measurement is performed using the full coverage of the ALICE detectors, -5.0 < eta < 5.5, and employing a special analysis technique based on collisions arising from LHC 'satellite' bunches. We present the pseudorapidity density as a function of the number of participating nucleons as well as an extrapolation to the total number of produced charged particles (N-ch = 17165 +/- 772 for the 0-5% most central collisions). From the measured dN(ch)/d eta distribution we derive the rapidity density distribution, dN(ch)/dy, under simple assumptions. The rapidity density distribution is found to be significantly wider than the predictions of the Landau model. We assess the validity of longitudinal scaling by comparing to lower energy results from RHIC. Finally the mechanisms of the underlying particle production are discussed based on a comparison with various theoretical models. (C) 2013 CERN. Published by Elsevier B.V. All rights reserved.

TI Low-lying T=0 states in the odd-odd N = Z nucleus Ga-62 SO PHYSICS LETTERS B LA English DT Article DE Isospin; N = Z; Levels; Shell-model; IBM-4 ID TO-Z NUCLEI; DATA SHEETS; SHELL-MODEL AB New, low-lying levels in the odd-odd, N = Z nucleus Ga-62 have been identified using a sensitive technique, where in-beam gamma rays from short-lived nuclei are tagged with beta decays following recoil mass identification. A comparison of the results with shell-model and IBM-4 calculations demonstrates good agreement between theory and experiment, with the majority of predicted low-lying, low-spin T = 0 states now identified. There is a dramatic change in the level density at low excitation energies for the N = Z nucleus Ga-62 when compared with neighbouring odd-odd Ga isotopes where, in contrast, the low-lying level structure is dominated by configurations with T = 1 pairing interactions between excess neutrons. This illustrates the distinctively different aspects of nuclear structure exhibited by nuclei with N = Z. (C) 2013 Elsevier B.V. All rights reserved. C1 [David, H. M.; Woods, P.

TI Quasi-particle and collective magnetism: Rotation, pairing and blocking in high-K isomers SO PHYSICS LETTERS B LA English DT Article ID STATES AB For the first time, a wide range of collective magnetic g-factors g(R), obtained from a novel analysis of experimental data for multi-quasi-particle configurations in high-K isomers, is shown to exhibit a striking systematic variation with the relative number of proton and neutron quasi-particles, N-p - N-n. Using the principle of additivity, the quasi-particle contribution to magnetism in high-K isomers of Lu-Re, Z = 71-75, has been estimated. Based on these estimates, band-structure branching ratio data are used to explore the behavior of the collective contribution as the number and proton/neutron nature (N-p, N-n), of the quasi-particle excitations, change. Basic ideas of pairing, its quenching by quasi-particle excitation and the consequent changes to moment of inertia and collective magnetism are discussed. Existing model calculations do not reproduce the observed gR variation adequately. The paired superfluid system of nucleons in these nuclei, and their excitations, present properties of general physics interest. The new-found systematic behavior of gR in multi-quasi-particle excitations of this unique system, showing variation from close to zero for multi-neutron states to above 0.5 for multi-proton states, opens a fresh window on these effects and raises the important question of just which nucleons contribute to the 'collective' properties of these nuclei.

TI Conserved number fluctuations in a hadron resonance gas model SO PHYSICS LETTERS B LA English DT Article DE Hadron resonance gas; Susceptibilities; Higher moments; Fluctuations; Heavy-ion collisions; Critical point ID HEAVY-ION COLLISIONS; PHASE-TRANSITION; FREEZE-OUT AB Net-baryon, net-charge and net-strangeness number fluctuations in high energy heavy-ion collisions are discussed within the framework of a hadron resonance gas (HRG) model. Ratios of the conserved number susceptibilities calculated in HRG are being compared to the corresponding experimental measurements to extract information about the freeze-out condition and the phase structure of systems with strong interactions. We emphasize the importance of considering the actual experimental acceptances in terms of kinematics (pseudorapidity (eta) and transverse momentum (p(T))), the detected charge state, effect of collective motion of particles in the system and the resonance decay contributions before comparisons are made to the theoretical calculations. In this work, based on HRG model, we report that the net-baryon number fluctuations are least affected by experimental acceptances compared to the net-charge and net-strangeness number fluctuations.

Thermal conductivity results show 16-fold increase in thermal conductivity from 0.49W m(-1) K-1 to 8W m(-1) K-1 upon post deposition annealing, partially due to the suppression of the number of the -OH/H2O bonds in the films after annealing. Thermal conductivity of the annealed film was similar to 70% lower than undoped bulk single crystal yttria. The cumulative interface thermal resistivity of substrate-Er+3:Y2O3-metal heater was determined to be similar to 2.5 x 10(-8) m(2) K/W. (C) 2013 AIP Publishing LLC.

TI Modelling transport in nanoparticle organic solar cells using Monte Carlo methods SO APPLIED PHYSICS LETTERS LA English DT Article ID PHOTOVOLTAIC DEVICES; AQUEOUS DISPERSION AB Water-based nanoparticle (NP) organic solar cells eliminate the need for harmful organic solvents during deposition. However, the core-shell NP structure should limit charge extraction resulting in poor performance. Here, we use dynamic Monte Carlo modelling to show that for optimised NP structures the core-shell character does not severely limit performance. Simulations further reveal that small NPs are more susceptible to extensive phase segregation, which diminishes charge carrier percolation pathways from the cores to the electrodes and thus inhibits charge extraction. Simulated performance behaviour was used to propose an explanation for the experimentally observed change in performance due to annealing. (C) 2013 AIP Publishing LLC. C1 [Feron, K.; Fell, C.

The submicron LSMO-dot structures underneath the ferroelectric PTO film allow exploring gradual changes in material properties. The LSMO interfacial layer influences significantly both electrical and ferroelectric properties of the upper PTO layer. The obtained results show that the as-grown polarization state of an epitaxial ferroelectric layer is strongly influenced by the properties of the layer on top of which it is deposited.

In particular, a number of methods have been proposed to determine the out-of-plane particle depth (z location). However, due to the lack of consistent uncertainty characterization, it has been unclear which method is best suited to a given measurement problem. In this work, depth determination accuracies of seven particle detection methods, including a recently proposed hybrid method, are systematically investigated in terms of relative depth measurement errors and uncertainties. Both synthetic and experimental holograms of particle fields are considered at conditions relevant to particle sizing and tracking. While all methods display a range of particle conditions where they are most accurate, in general the hybrid method is shown to be the most robust with depth uncertainty less than twice the particle diameter over a wide range of particle field conditions.

TI Polar and Magnetic Layered A-Site and Rock Salt B-Site-Ordered NaLnFeWO(6) (Ln = La, Nd) Perovskites SO INORGANIC CHEMISTRY LA English DT Article ID FERROELECTRIC POLARIZATION; NEUTRON-DIFFRACTION; MAGNETORESISTANCE; CATIONS; WO3 AB We have expanded the double perovskite family of materials with the unusual combination of layered order in the A sublattice and rock salt order over the B sublattice to compounds NaLaFeWO6 and NaNdFeWO6. The materials have been synthesized and studied by powder X-ray diffraction, neutron diffraction, electron diffraction, magnetic measurements, X-ray absorption spectroscopy, dielectric measurements, and second harmonic generation. At room temperature, the crystal structures of both compounds can be defined in the noncentrosymmetric monoclinic P2(1) space group resulting from the combination of ordering both in the A and B sublattices, the distortion of the cell due to tilting of the octahedra, and the displacement of certain cations. The magnetic studies show that both compounds are ordered antiferromagnetically below T-N approximate to 25 K for NaLaFeWO6 and at similar to 21 K for NaNdFeWO6. The magnetic structure of NaNdFeWO6 has been solved with a propagation vector k = (1/2 0 1/2) as an antiferromagnetic arrangement of Fe and Nd moments. Although the samples are potential multiferroics, the dielectric measurements do not show a ferroelectric response. C1 [Retuerto, M.; Li, M.

TI Polyclusters and Substitution Effects in the Na-Au-Ga System: Remarkable Sodium Bonding Characteristics in Polar Intermetallics SO INORGANIC CHEMISTRY LA English DT Article ID QUASI-CRYSTALLINE APPROXIMANTS; PHASES; INDIUM; GOLD; TETRAHEDRA; CLUSTERS; GALLIUM; NETWORK; LA AB A systematic exploration of Na- and Au-poor parts of the Na-Au-Ga system (less than 15 at. % Na or Au) uncovered several compounds with novel structural features that are unusual for the rest of the system. Four ternary compounds Na1.00(3)Au0.18Ga1.82(1) (I), NaAu2Ga4 (II), Na5Au10Ga16 (III), and NaAu4Ga2 (IV) have been synthesized and structurally characterized by single crystal X-ray diffraction: Na1.00(3)Au0.18Ga1.82(1)(I, P6/mmm, a = 15.181(2), c =9.129(2)angstrom, Z = 30); NaAu2Ga4 (II, Pnma, a = 16.733(3), b = 4.3330(9), c =7.358(3) angstrom, z = 4); Na5Au10Ga16 (III, P6(3)/m, a = 10.754(2), c =11.457(2) angstrom, Z = 2); and NaAu4Ga2 (IV, P2(1)/c, a = 8.292(2), b = 7.361(1), c =9.220(2)angstrom, beta = 116.15(3), Z = 4). Compound I lies between the large family of Bergman-related compounds and Na-poor Zintl-type compounds and exhibits a clathrate-like structure containing icosahedral clusters similar to those in cubic 1/1 approximants, as well as tunnels with highly disordered cation positions and fused Na-centered clusters. Structures II, III, and IV are built of polyanionic networks and clusters that generate novel tunnels in each that contain isolated, ordered Na atoms. Tight-binding electronic structure calculations using linear muffin-tin-orbital (LMTO) methods on II, III, IV and an idealized model of I show that all are metallic with evident pseudogaps at the Fermi levels. The integrated crystal orbital Hamilton populations for II-IV are typically dominated by Au-Ga, Ga-Ga, and Au-Au bonding, although Na-Au and Na-Ga contributions are also significant. Sodium's involvement into such covalency is consistent with that recently reported in Na-Au-M (M = Ga, Ge, Sn, Zn, and Cd) phases.

These cobalt(III) complexes with proton-responsive ligands predominantly exist in their deprotonated [Cp*Co(DHBP-2H(+))(OH2)] forms with stronger electron-donating properties in neutral and basic solutions, and are active catalysts for CO2 hydrogenation in aqueous bicarbonate media at moderate temperature under a total 4-5 MPa (CO2:H-2 1:1) pressure. The cobalt complexes containing 4DHBP ligands ([1-OH2](2+) and [1-Cl](+), where 1 = Cp*Co(4DHBP)) display better thermal stability and exhibit notable catalytic activity for CO2 hydrogenation to formate in contrast to the catalytically inactive nonsubstituted bpy analogues [3-OH2](2+) (3 = Cp*Co(bpy)). While the catalyst Cp*Ir(6DHBP)(OH2)(2+) in which the pendent oxyanion lowers the barrier for H-2 heterolysis via proton transfer through a hydrogen-bonding network involving a water molecule is remarkably effective (ACS Catal. 2013, 3, 856-860), cobalt complexes containing 6DHBP ligands ([2-OH2](2+) and [2-Cl](+), 2 = Cp*Co(6DHBP)) exhibit lower TOF and TON for CO2 hydrogenation than those with 4DHBP. The low activity is attributed to thermal instability during the hydrogenation of CO2 as corroborated by DFT calculations.

TI P-31 Magic Angle Spinning NMR Study of Flux-Grown Rare-Earth Element Orthophosphate (Monazite/Xenotime) Solid Solutions: Evidence of Random Cation Distribution from Paramagnetically Shifted NMR Resonances SO INORGANIC CHEMISTRY LA English DT Article ID PAIR DISTRIBUTION FUNCTION; 1ST PRINCIPLES CALCULATIONS; STATE NMR; MAS NMR; LOCAL ENVIRONMENTS; X-RAY; CATHODE MATERIALS; HYPERFINE SHIFTS; MONAZITE; SPECTROSCOPY AB We present P-31 magic angle spinning nuclear magnetic resonance spectra of flux-grown solid solutions of La1-xCexPO4 (x between 0.027 and 0.32) having the monoclinic monazite structure, and of Y1-xMxPO4 (M = Vn+, Ce3+, Nd3+, x between 0.001 and 0.014) having the tetragonal zircon structure. Paramagnetically shifted NMR resonances are observed in all samples due to the presence of paramagnetic Vn+, Ce3+, and Nd3+ in the diamagnetic LaPO4 or YPO4. As a first-order observation, the number and relative intensities of these peaks are related to the symmetry and structure of the diamagnetic host phase. The presence of paramagnetic shifts allows for increased resolution between NMR resonances for distinct atomic species which leads to the observation of low intensity peaks related to PO4 species having more than one paramagnetic neighbor two or four atomic bonds away. Through careful analysis of peak areas and comparison with predictions for simple models, it was determined that solid solutions in the systems examined here are characterized by complete disorder (random distribution) of diamagnetic La3+ or Y3+ with the paramagnetic substitutional species Ce3+ and Nd3+. The increased resolution given by the paramagnetic interactions also leads to the observation of splitting of specific resonances in the P-31 NMR spectra that may be caused by local, small-scale distortions from the substitution of ions having dissimilar ionic radii.

TI Fullerene "Superhalogen" Radicals: the Substituent Effect on Electronic Properties of 1,7,11,24,27-C60X5 SO CHEMISTRY-A EUROPEAN JOURNAL LA English DT Article DE electron affinity; fullerenes; photoelectron spectroscopy; radicals; superhalogen ID PHOTOELECTRON-SPECTROSCOPY; REDUCTION POTENTIALS; MASS-SPECTROMETRY; C-60; PERFLUOROALKYLFULLERENES; DERIVATIVES; DFT AB Hexasubstituted fullerenes with the skew pentagonal pyramid (SPP) addition pattern are predominantly formed in many types of reactions and represent important and versatile building blocks for supramolecular chemistry, biomedical and optoelectronic applications. Regioselective synthesis and characterization of the new SPP derivative, C-60(CF3)(4)(CN)H, in this work led to the experimental identification of the new family of superhalogen fullerene radicals, species with the gas-phase electron affinity higher than that of the most electronegative halogens, F and Cl. Low-temperature photoelectron spectroscopy and DFT studies of different C60X5 radicals reveal a profound effect of X groups on their electron affinities (EA), which vary from 2.76eV (X=CH3) to 4.47eV (X=CN). The measured gas-phase EA of the newly synthesized C-60(CF3)(4)CN equals 4.28(1)eV, which is about 1eV higher than the EA of Cl atom. An observed remarkable stability of C-60(CF3)(4)CN- in solution under ambient conditions opens new venues for design of air-stable molecular complexes and salts for supramolecular structures of electroactive functional materials.

These are supersymmetric avatars of impurity models. In the presence of additional sources such configurations are shown to preserve half of the supersymmetries. Mirror symmetry relates the two sets of configurations. We discuss the implications for impurity models in 3d N = 4 QED with a single charged hypermultiplet (and its mirror, the theory of a free hypermultiplet) as well as 3d N = 2 QED with one flavor and its dual, a supersymmetric Wilson-Fisher fixed point. Mirror symmetry allows us to find backreacted solutions for arbitrary arrays of defects in the IR limit of N = 4 QED. Our analysis, complemented with appropriate string theory brane constructions, sheds light on various aspects of mirror symmetry, the map between particles and vortices and the emergence of ground state entropy in QED at finite density.

TI Hybrid spin noise spectroscopy and the spin Hall effect SO PHYSICAL REVIEW B LA English DT Article ID SEMICONDUCTORS AB Here we suggest a hybrid spin noise spectroscopy technique, which is sensitive to the spin Hall effect. Our main idea is to study correlations between transverse voltage fluctuations and spin polarization fluctuations, which appear as a result of spin-charge coupling that is fundamental for the spin Hall effect. It is shown that, while the standard spin-spin correlation function is not sensitive to the spin Hall effect, spin-transverse voltage and transverse voltage-transverse voltage correlation functions provide the missing sensitivity, which is linear and quadratic in the spin Hall coefficient, respectively. We anticipate that the proposed method could find applications in studies of spin-charge coupling in semiconductors and other materials.

TI Comparative study of nuclear effects in polarized electron scattering from He-3 SO PHYSICAL REVIEW C LA English DT Article ID DEEP-INELASTIC-SCATTERING; SPIN STRUCTURE FUNCTIONS; 3-NUCLEON BOUND-STATES; BJORKEN SUM-RULE; MAGNETIC MOMENTS; BETA-DECAY; DEUTERON; ELECTROPRODUCTION; TARGETS; DISTRIBUTIONS AB We present a detailed analysis of nuclear effects in inclusive electron scattering from polarized He-3 nuclei for polarization asymmetries, structure functions, and their moments, in both the nucleon-resonance and deep-inelastic regions. We compare the results of calculations within the weak binding approximation at finite Q(2) with the effective polarization ansatz often used in experimental data analyses and explore the impact of Delta components in the nuclear wave function and nucleon off-shell corrections on extractions of the free neutron structure. Using the same framework we also make predictions for the Q(2) dependence of quasielastic scattering from polarized He-3, data which can be used to constrain the spin-dependent nuclear smearing functions in He-3.

However, the development of magnesium battery has been hindered by the limited performance and the lack of fundamental understandings of electrolytes. Here, we present a study in understanding coordination chemistry of Mg(BH4)(2) in ethereal solvents. The O donor denticity, i.e. ligand strength of the ethereal solvents which act as ligands to form solvated Mg complexes, plays a significant role in enhancing coulombic efficiency of the corresponding solvated Mg complex electrolytes. A new electrolyte is developed based on Mg(BH4)(2), diglyme and LiBH4. The preliminary electrochemical test results show that the new electrolyte demonstrates a close to 100% coulombic efficiency, no dendrite formation, and stable cycling performance for Mg plating/stripping and Mg insertion/de-insertion in a model cathode material Mo6S8 Chevrel phase.

CA CMS Collaboration TI Search for a Higgs boson decaying into a Z and a photon in pp collisions at root s=7 and 8 TeV SO PHYSICS LETTERS B LA English DT Article DE CMS; Physics; Higgs ID PARTON DISTRIBUTIONS; ATLAS DETECTOR; LHC; PARTICLE; COUPLINGS; CMS AB A search for a Higgs boson decaying into a Z boson and a photon is described. The analysis is performed using proton-proton collision datasets recorded by the CMS detector at the LHC. Events were collected at center-of-mass energies of 7 TeV and 8 TeV, corresponding to integrated luminosities of 5.0 fb(-1) and 19.6 fb(-1), respectively. The selected events are required to have opposite-sign electron or muon pairs. No excess above standard model predictions has been found in the 120-160 GeV mass range and the first limits on the Higgs boson production cross section times the H -> Z gamma branching fraction at the LHC have been derived. The observed at 95% confidence level limits are between about 4 and 25 times the standard model cross section times the branching fraction. For a standard model Higgs boson mass of 125 GeV the expected limit at the 95% confidence level is 10 and the observed limit is 9.5. Models predicting the Higgs boson production cross section times the H -> Z gamma branching fraction to be larger than one order of magnitude of the standard model prediction are excluded for most of the 125-157 GeV mass range.

A new CFD model is developed to predict single-phase fluid flow in headers with multiple parallel ports. This CFD model applies the porous jump interior condition in order to reduce the computational domain. In addition, Non Uniform Rational B-Splines (NURBS) are used to define and manipulate the header outer shape with the purpose of reducing the mass flow rate maldistribution. Design optimization is performed using a multiobjective genetic algorithm while the computational cost due to CFD analysis is reduced significantly by applying an online approximation technique. Optimization is performed to reduce both the mass flow rate maldistribution in different ports and the header frontal area with respect to the total heat exchanger frontal area. The optimization results predicted from metamodels are verified using CFD runs with high accuracy of prediction. (C) 2012 Elsevier Ltd. All rights reserved.

In the genomics age, the study of plant secondary metabolite biosynthesis has been transformed by various genomic tools. The field of metabolomics is continuingly adding novelty and complexity to our information on the chemistry of plant secondary metabolism. The availability of whole-genome sequences for an ever-increasing list of plants enables our examination of the genomic basis of secondary metabolite production. By integrating large-scale sequencing/bioinformatics, metabolomics, transcriptomics, proteomics and in vitro biochemistry, functional genomics holds the promise of expediting functional characterization of genes of plant secondary metabolism. Overall, the increasing volume of biochemical knowledge about plant metabolism, together with the genetic and molecular tools generated in recent years, paves the way for rationally designed, more effective genetic engineering of plant secondary metabolism for enhanced plant defense, improved quality and production of valuable chemicals, and many other applications.

Methods and Results: Twenty-nine SSR markers (di- and tetranucleotide repeats) were developed from DNA sequences obtained from 192 clones from an enriched genomic library of M. sinensis. All markers were successfully amplified in M. sacchariflorus, M. sinensis, and M. xgiganteus, and 19 amplified across a broad range of Miscanthus species. Polymorphism information content and expected heterozygosity values (19 locus sample) were 0.88 and 0.89, respectively, for M. sinensis, 0.48 and 0.54 for M. sacchariflorus, and were the lowest in M. xgiganteus (0.33, 0.41). Thirteen out of 19 primer pairs showed cross-species amplification in non-Miscanthus sensu stricto taxa. Conclusions: The new set of 29 SSR markers will be of high value for characterizing Miscanthus germplasm collections, for prebreeding, and for assessing variation in natural populations.

TI Reynolds Stress Relaxation Turbulence Modeling Applied to a Wingtip Vortex Flow SO AIAA JOURNAL LA English DT Article ID NEAR-FIELD; TIP VORTEX; SIMULATION; CURVATURE AB A Reynolds stress relaxation model, specifically the lag Reynolds stress transport model, is applied to a wingtip vortex flow, and its performance is assessed and compared with other aerospace standard turbulence models. A Reynolds stress relaxation model allows for Reynolds stress history effects due to streamline curvature, which are seen to play an important role in the nondiffusive nature of turbulent vortices. This study shows that the lag Reynolds stress transport turbulence model is capable of predicting mean flow results as accurately as those of the well-performing Spalart-Allmaras model with correction for streamline curvature and system rotation. Furthermore, in this wingtip vortex flow, the lag Reynolds stress transport model predicts turbulence quantities more accurately than the rotation/curvature-corrected Spalart-Allmaras model. Although the lag Reynolds stress transport model well predicts this flow, it is more computationally intensive to solve than the rotation/curvature-corrected Spalart-Allmaras model, and it has some deficiencies, such as an inability to independently control the Reynolds stress magnitude and relaxation amount.

As a new experimental approach to observe the soot cake during its oxidation, an environmental scanning electron microscope (ESEM) was utilized. The dynamic deformation process of the soot cake was revealed, and the contact conditions between the soot cake and the DPF wall, which is important in catalytic soot oxidation, were examined. In addition, thermogravimetric analysis (TGA) was performed and the specific reaction rate was determined. The effect of gas diffusion into the soot cake on the overall oxidation reaction rate was demonstrated. The soot cake oxidation behavior was discussed based on the ESEM observation and TGA results.

The graphical model and the compartment modeling gave similar estimates to the data and similar values (correlation R = .988; p = .0001). [C-11] Vorozole shows a rapid uptake by the brain followed by a relatively constant accumulation, suggesting the possibility of using the tissue to plasma ratio as an estimate of V-T. The highest uptake of [C-11] vorozole in the baboon brain was measured in the amygdala, followed by the preoptic area and hypothalamus, basal ganglia, and cortical areas. Pretreatment studies with vorozole or letrozole showed a generalized decrease in brain accumulation and V-T. The results suggested that the physiologic changes in gonadal hormone levels accompanying the menstrual cycle had a significant effect on brain aromatase V-T.

We report the existence of a critical layer thickness at which strength achieves optimal thermal stability. Transmission electron microscopy and theoretical bicrystal calculations show that this optimum arises due to a transition from thermally activated glide within the layers to dislocation transmission across the layers. We demonstrate experimentally that the atomic-scale properties of the interfaces profoundly affect this critical transition. The strong implications are that interfaces can be tuned to achieve an optimum in high temperature strength in layered nanocomposite structures. (C) 2013 Author(s).

Reciprocal space maps clearly show the disappearance of the integer-order Bragg peak splitting associated with the monoclinic phase when the film thickness decreases below 20 unit cells. This monoclinic-to-tetragonal transition is accompanied by the evolution of the half-order diffraction peaks, which reflects untilting of the oxygen octahedra around the [110] axis, proving that the octahedral tilting is closely correlated with the transition. This structural change is thickness-dependent, and different from a strain-induced transition in the conventional sense. (C) 2013 Author(s).

The state-of-the-art aberration corrected scanning transmission electron microscopy (Cs-corrected STEM) and the modified geometric phase analysis (GPA) have been used to characterize the self-assembled transitional layers, misfit defects, and, in particular, the biaxial lattice strain distributions. We found that not only a sufficient lattice misfit is required through substrate selection and to be preserved in initial coherent epilayer growth, but also an appropriate interfacial reconstruction is crucial for triggering the growth of the new BFMO322 supercell structure. The observation of new transitional interfacial phases behaving like coherent film layers within the critical thickness challenges the conventional understanding in existing epitaxial growth model.

TI Friction Consolidation of MA956 powder SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article; Proceedings Paper CT 15th International Conference on Fusion Reactor Materials CY OCT 16-22, 2013 CL Charleston, SC ID FBR CORE APPLICATION; FERRITIC ALLOYS; DISPERSION; RECRYSTALLIZATION; IMPROVEMENT; YTTRIUM; STEELS AB The applicability of Friction Consolidation (FC) to process an oxide dispersion strengthened (ODS) steel was studied to tackle the downsides of the conventional processing route (high complexity, extremely high raw material final cost). In this work, MA956 ODS powders have been consolidated through the FC process and small compacts of low porosity have been achieved with the desired oxide dispersion. The friction-consolidated sample shows a range of grain sizes when measuring at different locations within the cross section of the sample, and the values were all finer than those of a conventionally-processed sample. With regard to shape, grains in the friction-consolidated sample show an equiaxed cross section. Three particle families were observed: Y-Al-O, Al-O and Ti(C, N). The Y-Al-O and the Al-O were observed in both the conventionally-and the friction-consolidated sample. This result points out the ability to achieve the precipitation of the Y-Al-O by FC. The Ti(C, N) particles were only observed in the conventionally processed sample. The transmission electron microscopy images showed regions with smaller particles on the friction-consolidated sample. However, due to the extremely localized nature of the measurement, more data should be generated and analyzed to make this observation more statistically reliable. Published by Elsevier B.V.

TI Diffusion of small He clusters in bulk and grain boundaries in alpha-Fe SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article; Proceedings Paper CT 15th International Conference on Fusion Reactor Materials CY OCT 16-22, 2013 CL Charleston, SC ID 1ST PRINCIPLES; DIMER METHOD; BCC IRON; HELIUM; ALLOYS; INTERSTITIALS; RADIATION; TRANSPORT; DEFECTS AB The diffusion properties of He interstitials and He clusters in the bulk and grain boundaries (GBs) of alpha-Fe have been studied using molecular dynamics with a newly developed Fe-He potential. The low migration energy barrier for a single He interstitial in the bulk is consistent with that obtained using ab initio methods. Small He clusters can migrate at low temperatures, but at higher temperatures they will kick out a self-interstitial atom (SIA) and become trapped by the vacancy, forming an He-vacancy complex. It is of great interest to note that small He-n-vacancy clusters (n < 5) in the bulk are able to absorb an SIA, and the clusters become mobile again. Trapping and de-trapping of He clusters by emitting and absorbing an SIA represent an important dynamic process that provides a mechanism for the diffusion of He clusters and the nucleation of He bubbles in bulk Fe, particularly under irradiation in which numerous SIAs and vacancies are constantly being produced. A single He interstitial can migrate one-dimensionally or two-dimensionally within GBs, depending on the GB structure. Small interstitial He-n clusters (n similar to 1-10) can easily kick out an SIA, and become trapped by the vacancy, while the SIA quickly diffuses away from the clusters, disappearing into the GB, such that de-trapping of the He clusters by absorbing an SIA is less likely to occur. This suggests that small He clusters may be treated as relatively immobile defects in GBs. The different behavior of He clusters in the bulk compared to their behavior in GBs may explain the different He bubble sizes experimentally observed in the bulk and in GBs in reduced activation ferritic/martensitic steels that have been simultaneously neutron irradiated and He implanted.

Post-irradiation tests revealed hardening in weldment (WM) and base metal (BM) greater than 300 MPa. However, the heat affected zones (HAZ) exhibit about half that of WM and BM. Therefore, neutron irradiation decreased the strength of the HAZ, leaving it in danger of local deformation in this region. Further the hardening in WM made with an electron beam was larger than that in WM made with tungsten inert gas welding. However the mechanical properties of the diffusion-welded joint were very similar to those of BM even after the irradiation. (C) 2013 Elsevier B.V. All rights reserved.

TI Joining of 14YWT and F82H by friction stir welding SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article; Proceedings Paper CT 15th International Conference on Fusion Reactor Materials CY OCT 16-22, 2013 CL Charleston, SC ID FERRITIC ALLOY 14YWT; MECHANICAL-PROPERTIES; STRENGTH; STEEL AB Friction stir welding was investigated for joining specimens of the ODS 14YWT ferritic alloy together and to an F82H tempered martensitic steel plate. The FSW run was performed using a polycrystalline boron nitride tool and resulted in good bonding between 14YWT/14YWT and 14YWT/F82H. Joints and interfaces were observed by light microscopy and SEM analysis to be narrow in width. The ultra-small grain size of 14YWT increased by a factor up to 4 while that of F82H decreased by a considerable amount in the weld zones. The TEM analysis showed no significant changes in the size of the oxygen-enriched nanoclusters in the weld zone of 14YWT. However, defects such as a wormhole on the advancing side of the weld zone in 14YWT and small pores associated with joints and interfaces were observed in the FSW sample. The hardness measurements from unaffected zone into weld zones showed similar to 20% decrease in hardness for 14YWT (from similar to 500 VH to similar to 380 VH) and similar to 100% increase in hardness of F82H (from similar to 220 VH to similar to 440 VH).

TI Microstructural evolution in proton irradiated NF616 at 773 K to 3 dpa SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article; Proceedings Paper CT 15th International Conference on Fusion Reactor Materials CY OCT 16-22, 2013 CL Charleston, SC ID REACTORS; ALLOYS; STEELS AB Ferritic-martensitic (FM) steels have been widely considered as structural materials for future fusion and fission systems due to their excellent swelling resistance and other properties under irradiation. NF616 is a newer generation FM steel that provides higher allowable operating temperatures, but there is limited information on the development of irradiated microstructures or associated mechanical properties in NF616. Studying the irradiation-induced defects as a function of dose could help to better understand the mechanisms of damage evolution. Proton irradiation at 773 K, up to 1, 2 and 3 dpa, was performed on NF616 to investigate damage evolution at different doses. Irradiation-induced defects, such as clusters, loops and dislocations, were investigated. (C) 2013 Elsevier B.V. All rights reserved. C1 [Huang, Y.; Allen, T.

TI Tritium trapping in silicon carbide in contact with solid breeder under high flux isotope reactor irradiation SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article; Proceedings Paper CT 15th International Conference on Fusion Reactor Materials CY OCT 16-22, 2013 CL Charleston, SC ID SIC/SIC COMPOSITES; SICF/SIC COMPOSITES; NEUTRON-IRRADIATION; COMPATIBILITY; BEHAVIOR AB The trapping of tritium in silicon carbide (SiC) injected from ceramic breeding materials was examined via tritium measurements using imaging plate (IP) techniques. Monolithic SiC in contact with ternary lithium oxide (lithium titanate and lithium aluminate) as a ceramic breeder was irradiated in the High Flux Isotope Reactor (HFIR) in Oak Ridge, Tennessee, USA. The distribution of photo-stimulated luminescence (PSL) of tritium in SiC was successfully obtained, which separated the contribution of C-14 beta-rays to the PSL. The tritium incident from ceramic breeders was retained in the vicinity of the SiC surface even after irradiation at 1073 K over the duration of similar to 3000 h, while trapping of tritium was not observed in the bulk region. The PSL intensity near the SiC surface in contact with lithium titanate was higher than that obtained with lithium aluminate. The amount of the incident tritium and/or the formation of a Li2SiO3 phase on SiC due to the reaction with lithium aluminate under irradiation likely were responsible for this observation.

The D retention for polished VPS-W/F82H after plasma exposure was found to be reduced compared to that for polycrystalline tungsten. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observations indicated that porous structures around grain boundaries and the interface between VPS-W layers would be potential D diffusion paths, leading to low D retention. In the case of D-2(+) implantation, the shape of D-2 TDS spectrum was almost the same as that for D plasma-exposed VPS-W/F82H; however, the D retention was quite high for unpolished VPS-W/F82H, indicating that most of D was trapped by the oxide layer, which was produced by the VPS process. The reduction of surface area due to the polishing process also reduces D retention for VPS-W/F82H. These results indicate that controlling the surface chemical states is important for the reduction of tritium retention for future fusion reactors. (C) 2013 Elsevier B.V. All rights reserved.

Higher wall temperatures could be achieved if compatibility issues can be controlled. Isothermal capsule experiments have demonstrated that thin (<50 mu m) Al-rich coatings on Gr.92 steel can reduce mass loss in Pb-Li for up to 5000 h at 700 degrees C (973 K) and that similar coating performance was obtained for coated oxide dispersion strengthened FeCr steels at 700 degrees C (973 K). Dissimilar material experiments at 700 degrees C (973 K) suggested a possible reaction between Fe and SiC in Pb-Li that needs to be further studied as it could limit the blanket temperatures.

TI Transmutation of silicon carbide in fusion nuclear environment SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article; Proceedings Paper CT 15th International Conference on Fusion Reactor Materials CY OCT 16-22, 2013 CL Charleston, SC ID BLANKET; PARAMETERS; REACTORS; DAMAGE; PLANT AB The amount and type of metallic transmutants produced in SiC/SiC when used in magnetic (MFE) and inertial (IFE) confinement fusion systems are determined and compared to those obtained following irradiation in fission reactors. Up to similar to 1.3% metallic transmutants are generated at the expected lifetime of the fusion blanket. Irradiation in fission reactors to the same fast neutron fluence produces about an order of magnitude lower metallic transmutation products than in fusion systems. While the dominant component in fusion systems is Mg, P is the main transmutation product in fission reactors. The impact on the SiC/SiC properties is not fully understood. The results of this work will help guide irradiation experiments in fission reactors to properly simulate the conditions in fusion systems by possible ion implantation. In addition, the results represent a necessary input for modeling activities aimed at understanding the expected effects on properties. (C) 2012 Elsevier B.V. All rights reserved. C1 [Sawan, M.

TI Molecular dynamics simulation of cascade-induced ballistic helium resolutioning from bubbles in iron SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article; Proceedings Paper CT 15th International Conference on Fusion Reactor Materials CY OCT 16-22, 2013 CL Charleston, SC ID GAS-BUBBLES; RE-SOLUTION; BCC IRON; DEFECT PROPERTIES; URANIUM-DIOXIDE; FISSION-GAS; IRRADIATION; NUCLEATION; ENERGY; DAMAGE AB Molecular dynamics simulations have been used to assess the ability of atomic displacement cascades to eject helium from small bubbles in iron. This study of the ballistic resolutioning mechanism employed a recently-developed Fe-He interatomic potential in concert with an iron potential developed by Ackland and co-workers. The primary variables examined were: irradiation temperature (100 and 600 K), cascade energy (5 and 20 keV), bubble radius (0.5 and 1.0 nm), and He-to-vacancy ratio in the bubble (0.25, 0.5 and 1.0). Systematic trends were observed for each of these variables. For example, ballistic resolutioning leads to a greater number of helium atoms being displaced from larger bubbles and from bubbles that have a higher He/vacancy ratio (bubble pressure). He resolutioning was reduced at 600 K relative to 100 K, and for 20 keV cascades relative to 5 keV cascades. Overall, the results indicate a modest level of He removal by ballistic resolutioning. The results may be particularly relevant to fusion irradiation conditions which produces high levels of helium by transmutation. They can be used to provide initial guidance in selection of a "resolution parameter" that can be employed in kinetic models to predict the bubble size distribution that evolves under irradiation.

TI Effects of alloying elements and thermomechanical treatment on 9Cr Reduced Activation Ferritic-Martensitic (RAFM) steels SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article; Proceedings Paper CT 15th International Conference on Fusion Reactor Materials CY OCT 16-22, 2013 CL Charleston, SC AB RAFM steels are one of the candidate structural materials for fusion reactors, in which tantalum (Ta) and tungsten (W) are alloyed to replace niobium (Nb) and molybdenum (Mo) in conventional FM steels, respectively. This paper, using three RAFM heats, presents the effects of Ta and the primary austenite stabilizer carbon (C) on microstructure and strength. Thermomechanical treatment (TMT) was also applied to the heats, leading to significant increases in strength, attributable to the TMT-refined sub-grains and precipitates. The Ta-alloying favored the formation of (V, Ta)(N, C) and (Ta, V) C and exhibited greater strength. Fractographs also revealed the beneficial effects of TMT and Ta-alloying. However, extra C content, favoring a larger amount of M23C6 precipitates, did not show strengthening effect. (C) 2012 Elsevier B. V. All rights reserved. C1 [Tan, L.; Yang, Y.; Busby, J.

TI Interaction of dislocations with Frank loops in Fe-Ni alloys and pure Ni: An MD study SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article; Proceedings Paper CT 15th International Conference on Fusion Reactor Materials CY OCT 16-22, 2013 CL Charleston, SC ID DEFECT INTERACTIONS; DYNAMICS; METALS; SIMULATIONS; COPPER; MODEL AB Variation of the stacking fault energy in FCC alloys and austenitic steels is well known to influence the evolution of radiation damage and its effect on deformation mechanisms. The primary defects observed in austenitic steels under neutron irradiation are mainly Frank loops. Here, we study the interaction of edge and screw dislocations with Frank loops in low stacking fault energy Fe-Ni alloys. The interatomic potentials employed were specially developed to reproduce a number of properties of real austenitic steels. The influence of temperature and loop morphology on the interaction mechanism and the critical resolved shear stress for dislocations to overcome loops has been investigated. All investigated reactions have been subdivided into three classes depending on temperature, loop size and interaction geometry. It is shown that by decreasing stacking fault energy below a certain value the formation of constrictions on dislocations is suppressed so that loop unfaulting becomes a less favorable mechanism in comparison with loop shear. Additional effect of solid-solution alloying, causing a non-negligible friction stress, is expressed in the impedance of the propagation of dislocations in the secondary glide planes, which is another factor limiting the unfaulting process.

Specimens of V-4Cr-4Ti exposed in the hot and cold legs of the loop and tensile tested in vacuum at 500 degrees C (773 K) showed an increase in the 0.2% yield and ultimate tensile strengths and a decrease in the serration amplitude with decreasing exposure temperature in the loop. However, only minor changes in ductility were measured. With the higher temperature exposures, a decrease in Vickers hardness was measured, but little change in the grain size was observed. Characterization of the microstructure after exposure at 627 degrees C (900 K) in the loop showed an increase in the density of Ti- and N-rich grain boundary and matrix precipitates near the specimen surface after exposure corresponding to an increase in the hardness in the near-surface region. Two-layer V/Y2O3 coatings on V-4Cr-4Ti substrates also were exposed in the loop, and initial room temperature characterization was conducted. Published by Elsevier B.V. C1 [Unocic, K. A.; Lance, M.

Because these materials are not common structural materials like steels, knowledge and strategies to improve the properties are still under development. These strategies discussed here, include new alloying approaches and microstructural stabilization by oxide dispersion strengthened as well as TiC stabilized tungsten based materials. The fracture behavior is improved by using tungsten laminated and tungsten wire reinforced materials. Material development is accompanied by neutron irradiation campaigns. Self-passivation, which is essential in case of loss-of-coolant accidents for plasma facing materials, can be achieved by certain amounts of chromium and titanium. Furthermore, modeling and computer simulation on the influence of alloying elements and heat loading and helium bombardment will be presented. (C) 2013 Elsevier B.V. All rights reserved.

By comparison of the almost simultaneous 2/4-probe measurements, the specific contact resistance (R-c) and its temperature dependence were determined for two types (sputtered gold and porous nickel) electrodes from room temperature (RT) to similar to 973 K. The R-c-values behaved similarly for each type of metallic electrode: R-c > similar to 1000 Omega cm(2) at RT, decreasing continuously to similar to 1-10 Omega cm(2) at 973 K. The temperature dependence of the inverse R-c indicated thermally activated electrical conduction across the SiC/metallic interface with an apparent activation energy of similar to 0.3 eV. For the flow channel insert application in a fusion reactor blanket, contact resistance potentially could reduce the transverse electrical conductivity by about 50%. (C) 2013 Elsevier B.V.

Recent studies have shown that hydrogenated TiO2 displayed better photocatalytic and lithium ion battery performances. Here it is demonstrated that the photocatalytic and battery performances of TiO2 nanocrystals can be successfully improved with a facile low-temperature vacuum process. These TiO2 nanocrystals extend their optical absorption far into the visible-light region, display nanometer-scale surface atomic rearrangement, possess superoxide ion characteristics at room temperature without light irradiation, show a 4-fold improvement in photocatalytic activity, and has 30% better performance in capacity and charge/discharge rates for lithium ion battery. This facile method could provide an alternative and effective approach to improve the performance of TiO2 and other materials towards their practical applications.

The skill of models that provide continental-scale carbon flux estimates, however, remains largely untested. This paper evaluates the performance of continental-scale flux estimates from 17 models against observations from 36 North American flux towers. Fluxes extracted from regional model simulations were compared with co-located flux tower observations at monthly and annual time increments. Site-level model simulations were used to help interpret sources of the mismatch between the regional simulations and site-based observations. On average, the regional model runs overestimated the annual gross primary productivity (5%) and total respiration (15%), and they significantly underestimated the annual net carbon uptake (64%) during the time period 2000-2005. Comparison with site-level simulations implicated choices specific to regional model simulations as contributors to the gross flux biases, but not the net carbon uptake bias. The models performed the best at simulating carbon exchange at deciduous broadleaf sites, likely because a number of models used prescribed phenology to simulate seasonal fluxes. The models did not perform as well for crop, grass, and evergreen sites. The regional models matched the observations most closely in terms of seasonal correlation and seasonal magnitude of variation, but they have very little skill at interannual correlation and minimal skill at interannual magnitude of variability. The comparison of site vs. regional-level model runs demonstrated that (1) the interannual correlation is higher for site-level model runs, but the skill remains low; and (2) the underestimation of year-to-year variability for all fluxes is an inherent weakness of the models. The best-performing regional models that did not use flux tower calibration were CLM-CN, CASA-GFEDv2, and SIB3.1. Two flux tower calibrated, empirical models, EC-MOD and MOD17 broken vertical bar, performed as well as the best process-based models. This suggests that (1) empirical, calibrated models can perform as well as complex, process-based models and (2) combining process-based model structure with relevant constraining data could significantly improve model performance.

TI Endovascular Catheter for Magnetic Navigation under MR Imaging Guidance: Evaluation of Safety In Vivo at 1.5T SO AMERICAN JOURNAL OF NEURORADIOLOGY LA English DT Article ID REMOTE-CONTROL; INTERVENTIONAL MRI; DEFLECTION AB BACKGROUND AND PURPOSE: Endovascular navigation under MR imaging guidance can be facilitated by a catheter with steerable microcoils on the tip. Not only do microcoils create visible artifacts allowing catheter tracking, but also they create a small magnetic moment permitting remote-controlled catheter tip deflection. A side product of catheter tip electrical currents, however, is the heat that might damage blood vessels. We sought to determine the upper boundary of electrical currents safely usable at 1.5T in a coil-tipped microcatheter system. MATERIALS AND METHODS: Alumina tubes with solenoid copper coils were attached to neurovascular microcatheters with heat shrink-wrap. Catheters were tested in carotid arteries of 8 pigs. The catheters were advanced under x-ray fluoroscopy and MR imaging. Currents from 0 mA to 700 mA were applied to test heating and potential vascular damage. Postmortem histologic analysis was the primary endpoint. RESULTS: Several heat-mitigation strategies demonstrated negligible vascular damage compared with control arteries. Coil currents 300 mA resulted in no damage (0/58 samples) compared with 9 (25%) of 36 samples for > 300-mA activations (P = .0001). Tip coil activation 1 minute and a proximal carotid guide catheter saline drip > 2 mL/minute also had a nonsignificantly lower likelihood of vascular damage. For catheter tip coil activations 300 mA for 1 minute in normal carotid flow, 0 of 43 samples had tissue damage. CONCLUSIONS: Activations of copper coils at the tip of microcatheters at low currents in 1.5T MR scanners can be achieved without significant damage to blood vessel walls in a controlled experimental setting. Further optimization of catheter design and procedure protocols is necessary for safe remote control magnetic catheter guidance. C1 [Hetts, S. W.; Saeed, M.; Martin, A.

Development of efficient cathode catalysts and stable electrolytes for the Li-air battery has been intensively investigated for the past several years, and a number of review articles covering different topics are already available. This review mainly focuses on the research activities on rechargeable non-aqueous Li-air batteries at Argonne National Laboratory, with the emphasis on the gains in understanding of electrolyte decomposition, the structure and magnetic properties of lithium peroxide (Li2O2), development of an air-breathing cathode, and the effect of oxygen crossover on the lithium anode. Insights from this research have led to the improvement of the electrochemical performance of Li-air batteries. Promising paths for future work on rechargeable Li-air batteries are also discussed.

TI Relocation of microseismicity using reflected waves from single-well, three-component array observations: Application to CO2 injection at the Aneth oil field SO INTERNATIONAL JOURNAL OF GREENHOUSE GAS CONTROL LA English DT Article DE Monitoring; Microseismicity; Source location; Reflected wave ID EARTHQUAKES; CALIFORNIA AB Passive microseismic measurement is an important tool for monitoring underground behavior during CO2 geosequestration; such monitoring is necessary for maintaining maximum long-term safety. It is however difficult to deploy an ideal observation network at reasonable cost for obtaining reliable source locations. In this paper, we show the re-analysis results of microseismicity detected on a single vertical borehole array deployed at the Aneth oil field, where CO2 injection was conducted for enhanced oil recovery operation. The objective of the re-analysis was to obtain improved source depth estimates. We first show possible translation of microseismic source locations from preliminary results based on detailed waveform observations and ray-path modeling using a 7-layer velocity model. Then, a source location method using multiple reflection waves and the relative source location method for many small slave events is proposed, and modified source location results are compared with those obtained by the standard location method. From the modified source depth distribution, we can infer that most of the microseismic events likely occurred as a result of injection salt water disposal and not by CO2 injection at the Aneth field. In general, the proposed analytical technique provides a more reliable understanding of underground changes during CO2 injection by improving the depth accuracy of microseismic activity.

TI A laboratory study of the initial effects of dissolved carbon dioxide (CO2) on metal release from shallow sediments SO INTERNATIONAL JOURNAL OF GREENHOUSE GAS CONTROL LA English DT Article DE Metal; Groundwater impact; CO2 ID FRESH-WATER RESOURCES; BATCH-REACTION EXPERIMENT; NATURAL ANALOG SITE; GROUNDWATER QUALITY; LEAKAGE; FIELD; IMPACTS; STORAGE; IRON; USA AB Sequestration of carbon dioxide (CO2) into deep geologic reservoirs is a potential approach for controlling the rise of CO2 concentrations in the atmosphere. Proper characterization and permitting of storage sites is expected to include an assessment of the potential impacts of CO2 intrusion into overlying groundwater formations. In most natural settings, the dissolution of CO2 into groundwater will decrease the pH and can also release carbonate ligands into solution. These effects can lead to metals being mobilized from sediments through mechanisms such as ion exchange, desorption, and mineral dissolution. This laboratory-based study evaluates the extent of metal release from a groundwater system in the presence of elevated CO2 concentrations. In particular, the research investigates the geochemical mechanisms involved in metal release, with a focus on distinguishing between pH-driven processes (e.g. carbonate dissolution and ion exchange) and carbonate-driven processes (e.g. reactions enhanced by the formation of metal-carbonate complexes). Measurements from lab-scale leaching experiments and sediment characterizations are compared to data from a concurrent controlled-release field test, where CO2 was injected into a poorly buffered sandy groundwater formation at 50 m depth. Results show that the immediate effect of the introduction of CO2 is a pH drop of 3 units, which leads to the quick release of some elements (e.g. Ca, Mg, Ba, Sr) by primarily pH-driven processes. The extent of metal release was different across geochemically distinct sediment types from the field site. The results suggest that it would be useful to group constituents by their pH-release trends, and to include pH and concentrations of certain indicator cations (Li, K, Na, Ba, Ca, Mg, Sr, Mn and Si) as parameters in site monitoring plans.

TI Characterization of pozzolan-amended wellbore cement exposed to CO2 and H2S gas mixtures under geologic carbon storage conditions SO INTERNATIONAL JOURNAL OF GREENHOUSE GAS CONTROL LA English DT Article DE Carbon sequestration; Acid gas; Wellbore cement; Pozzolan; CO2; H2S ID FLY-ASH; SEQUESTRATION CONDITIONS; INJECTION; CAPTURE AB Capture and subsurface co-sequestration of acid gas (a mixture of CO2 and H2S) is a geologic sequestration approach that can reduce the emission of both CO2 and sulfur-containing "sour" gas. To investigate the effects of co-sequestration on pozzolan-amended wellbore cement, samples were mixed, cured and exposed to mixtures of H2S and CO2 under geologic sequestration conditions (50 degrees C, 15.1 MPa) for various periods of time. The resulting samples were characterized using microscopy, X-ray diffraction, and microhardness testing. These analyses showed significant alteration at the surfaces of pozzolan-amended cement samples after 28 days of exposure to 21 mole% H2S in a mixture with CO2. Results of samples exposed for 28 days also revealed that the samples with higher pozzolan amount (65% pozzolan by volume) allowed faster CO2 and H2S penetrations than those with lower pozzolan amount (35% pozzolan by volume). Analyses showed that there was formation of carbonate species in the interior "core" region of pozzolan-amended cement samples with 65 vol% pozzolan after 28 days of exposure, which was not the case for the samples with 35 vol% pozzolan. In addition, the microhardness test results showed that the rim region of the 35 vol% pozzolan samples exhibited a higher microhardness than that of the core region for the same sample, whereas the different regions of the 65 vol% pozzolan samples exhibited similar microhardness values. In summary, the pozzolan-amended cement samples with 35 vol% pozzolan exhibited better H2S-resisting performance than the samples with 65 vol% pozzolan. Published by Elsevier Ltd.

In this modeling approach, the individual physical processes involved in hydraulic fracturing are identified and addressed as separate modules: (1) a rock-discontinuous-cellular-automaton method for continuous-discontinuous geomechanical fracturing analysis, and (2) an integrated finite volume method for representing non-isothermal, multiphase fluid-flow processes. With this approach, the real fracture propagation path (straight or curved) induced by CO2 injection can be modeled without the need for remeshing. We verify the method and the numerical model against analytical solutions for fracture opening and propagation. We then simulate CO2 injection-induced fracturing within a brine aquifer, demonstrating the capability and applicability of our coupled numerical method for simulating fracturing processes driven by multiphase fluid flow. Our study focuses on the role of initial caprock damage in geologic carbon sequestration, and how natural fractures could impact caprock sealing integrity. We find that, given initial damage or fracturing in the lower part of the caprock, injection-induced pressure can diffuse into the fracture and potentially propagate upwards across the caprock, creating a new flow path by which CO2 could migrate out of the intended storage aquifer. However, our modeling also shows that an injection pressure limited by minimum principal compressive stress (which might be estimated from leak-off or mini-frac tests) would be appropriate for safe injection with respect to maintaining caprock sealing integrity. Finally, our modeling also highlights the importance and usefulness of pressure and deformation monitoring potentially effective techniques for early detection of deep fracture propagation breaking through a caprock layer.

Understanding the detailed mechanism driving the homodimerization is important and will impact future studies targeting the "undruggable" oncogenic protein dimers. In this study, we used 14-3-3 sigma as a model homodimeric protein and performed a systematic investigation of the potential roles of amino acid residues in the interface for homodimerization. Unlike other members of the conserved 14-3-3 protein family, 14-3-3 sigma prefers to form a homodimer with two subareas in the dimeric interface that has 180 degrees symmetry. We found that both subareas of the dimeric interface are required to maintain full dimerization activity. Although the interfacial hydrophobic core residues Leu(12) and Tyr(84) play important roles in 14-3-3 sigma dimerization, the non-core residue Phe(25) appears to be more important in controlling 14-3-3 sigma dimerization activity. Interestingly, a similar non-core residue (Val(81)) is less important than Phe(25) in contributing to 14-3-3 sigma dimerization. Furthermore, dissociating dimeric 14-3-3 sigma into monomers by mutating the Leu(12), Phe(25), or Tyr(84) dimerization residue individually diminished the function of 14-3-3 sigma in resisting drug-induced apoptosis and in arresting cells at G(2)/M phase in response to DNA-damaging treatment. Thus, dimerization appears to be required for the function of 14-3-3 sigma.

TI Novel Insights into Eukaryotic gamma-Glutamyltranspeptidase 1 from the Crystal Structure of the Glutamate-bound Human Enzyme SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID SUBSTRATE-SPECIFICITY; TRANSFERASE TRANSPEPTIDASE; UNCOMPETITIVE INHIBITORS; CATALYTIC MECHANISM; ESCHERICHIA-COLI; PHASE-I; SEQUENCE; GLYCOSYLATION; GLUTATHIONE; ACIVICIN AB The enzyme gamma-glutamyltranspeptidase 1 (GGT1) is a conserved member of the N-terminal nucleophile hydrolase family that cleaves the gamma-glutamyl bond of glutathione and other gamma-glutamyl compounds. In animals, GGT1 is expressed on the surface of the cell and has critical roles in maintaining cysteine levels in the body and regulating intracellular redox status. Expression of GGT1 has been implicated as a potentiator of asthma, cardiovascular disease, and cancer. The rational design of effective inhibitors of human GGT1(hGGT1) has been delayed by the lack of a reliable structural model. The available crystal structures of several bacterial GGTs have been of limited use due to differences in the catalytic behavior of bacterial and mammalian GGTs. We report the high resolution (1.67 angstrom) crystal structure of glutamate-bound hGGT1, the first of any eukaryotic GGT. Comparisons of the active site architecture of hGGT1 with those of its bacterial orthologs highlight key differences in the residues responsible for substrate binding, including a bimodal switch in the orientation of the catalytic nucleophile (Thr-381) that is unique to the human enzyme. Compared with several bacterial counterparts, the lid loop in the crystal structure of hGGT1 adopts an open conformation that allows greater access to the active site. The hGGT1 structure also revealed tightly bound chlorides near the catalytic residue that may contribute to catalytic activity. These are absent in the bacterial GGTs. These differences between bacterial and mammalian GGTs and the new structural data will accelerate the development of new therapies for GGT1-dependent diseases.

TI Soil Carbon Change and Net Energy Associated with Biofuel Production on Marginal Lands: A Regional Modeling Perspective SO JOURNAL OF ENVIRONMENTAL QUALITY LA English DT Article ID LIFE-CYCLE ASSESSMENT; RESERVE PROGRAM CRP; ORGANIC-CARBON; BIOENERGY PRODUCTION; LONG-TERM; NO-TILL; PHYSICAL ATTRIBUTES; CROPPING SYSTEMS; CLIMATE-CHANGE; UNITED-STATES AB The use of marginal lands for biofuel production has been proposed as a promising solution for meeting biofuel demands while avoiding food-feed-fuel conflicts. However, uncertainty surrounds whether marginal lands can be reliably located, as well as their inherent biofuel potential and the possible environmental impacts. We developed a quantitative approach that integrates high-resolution land cover and land productivity to classify productive croplands and nonarable marginal lands in a nine-county region in southern Michigan. The classified lands were then examined with the spatially explicit modeling framework using the Environmental Policy Integrated Climate (EPIC) model to estimate net energy (NE) and soil organic carbon (SOC) changes associated with the cultivation of different annual and perennial production systems. Simulation results suggest that biofuel production systems underperform on marginal lands when compared to productive croplands. However, we found perennial grasses could perform better than annual crops. Hence, when growing perennial bioenergy crops on marginal lands instead of productive croplands, less additional land (about 0.09 ha per each hectare planted) would be needed to achieve the same NE than if growing annual bioenergy crops (additional 0.17 ha per hectare planted). Miscanthus (Miscanthus x giganteus) and switchgrass (Panicum virgatum L.) can produce 112.43 and 74.61 GJ ha(-1) yr(-1) NE, respectively, and have the potential to sequester, on average, 0.59 and 0.23 Mg C ha(-1) yr(-1) SOC, respectively. Notably, simulation results indicate substantial variability of the NE and SOC storage potential across the study region. Thus, although perennial energy crops are promising options for biofuel production on marginal lands, given the large spatial variability, regional-and site-specific management strategies are required for sustainable biofuel production.

TI Ultra-Deep Sequencing of Intra-host Rabies Virus Populations during Cross-species Transmission SO PLOS NEGLECTED TROPICAL DISEASES LA English DT Article ID GENE; BATS; CALIFORNIA; DIVERSITY AB One of the hurdles to understanding the role of viral quasispecies in RNA virus cross-species transmission (CST) events is the need to analyze a densely sampled outbreak using deep sequencing in order to measure the amount of mutation occurring on a small time scale. In 2009, the California Department of Public Health reported a dramatic increase (>350%) in the number of gray foxes infected with a rabies virus variant for which striped skunks serve as a reservoir host in Humboldt County. To better understand the evolution of rabies, deep-sequencing was applied to 40 unpassaged rabies virus samples from the Humboldt outbreak. For each sample, approximately 11 kb of the 12 kb genome was amplified and sequenced using the Illumina platform. Average coverage was 17,448x and this allowed characterization of the rabies virus population present in each sample at unprecedented depths. Phylogenetic analysis of the consensus sequence data demonstrated that samples clustered according to date (1995 vs. 2009) and geographic location (northern vs. southern). A single amino acid change in the G protein distinguished a subset of northern foxes from a haplotype present in both foxes and skunks, suggesting this mutation may have played a role in the observed increased transmission among foxes in this region. Deep-sequencing data indicated that many genetic changes associated with the CST event occurred prior to 2009 since several nonsynonymous mutations that were present in the consensus sequences of skunk and fox rabies samples obtained from 2003-2010 were present at the sub-consensus level (as rare variants in the viral population) in skunk and fox samples from 1995. These results suggest that analysis of rare variants within a viral population may yield clues to ancestral genomes and identify rare variants that have the potential to be selected for if environment conditions change.

SO PLOS PATHOGENS LA English DT Article ID HUMAN-IMMUNODEFICIENCY-VIRUS; CD8(+) T-CELLS; NECROSIS-FACTOR-ALPHA; LONG TERMINAL REPEAT; DYNAMICS IN-VIVO; ANTIGEN PRESENTATION; INTERFERON-GAMMA; VIRAL ESCAPE; LYMPH-NODE; ANTIRETROVIRAL THERAPY AB The CD8+ T cell effector mechanisms that mediate control of HIV-1 and SIV infections remain poorly understood. Recent work suggests that the mechanism may be primarily non-lytic. This is in apparent conflict with the observation that SIV and HIV-1 variants that escape CD8+ T cell surveillance are frequently selected. Whilst it is clear that a variant that has escaped a lytic response can have a fitness advantage compared to the wild-type, it is less obvious that this holds in the face of non-lytic control where both wild-type and variant infected cells would be affected by soluble factors. In particular, the high motility of T cells in lymphoid tissue would be expected to rapidly destroy local effects making selection of escape variants by non-lytic responses unlikely. The observation of frequent HIV-1 and SIV escape poses a number of questions. Most importantly, is the consistent observation of viral escape proof that HIV-1- and SIV-specific CD8+ T cells lyse infected cells or can this also be the result of non-lytic control? Additionally, the rate at which a variant strain escapes a lytic CD8+ T cell response is related to the strength of the response. Is the same relationship true for a non-lytic response? Finally, the potential anti-viral control mediated by non-lytic mechanisms compared to lytic mechanisms is unknown. These questions cannot be addressed with current experimental techniques nor with the standard mathematical models. Instead we have developed a 3D cellular automaton model of HIV-1 which captures spatial and temporal dynamics. The model reproduces in vivo HIV-1 dynamics at the cellular and population level. Using this model we demonstrate that non-lytic effector mechanisms can select for escape variants but that outgrowth of the variant is slower and less frequent than from a lytic response so that non-lytic responses can potentially offer more durable control.

Such misalignments can be caused by the seismic data processing workflow and may result in the wrong interpretation of time-lapse seismic amplitude differences. We propose an efficient local-correlation-based warping method of registering the time-lapse poststack data sets, which can align these data sets without changing original amplitudes. Application of our registration method to Cranfield time-lapse data demonstrates its effectiveness in separating time-shift character from seismic amplitude signature. After registration, time-lapse differences show an improved consistency in vertical cross sections and a more localized distribution of difference amplitudes along the horizon, allowing us to apply a high-resolution basis pursuit inversion (BPI) for acoustic impedances. Inversion results show that decreases in acoustic impedances occur mostly at the top of the injection interval, which can be used as an indicator of rock properties to detect a subsurface CO2 plume.

TI High-frequency seismic response during permeability reduction due to biopolymer clogging in unconsolidated porous media SO GEOPHYSICS LA English DT Article ID LEUCONOSTOC-MESENTEROIDES GROWTH; INSOLUBLE DEXTRAN; SATURATED ROCKS; ATTENUATION; WATER AB The accumulation of biopolymers in porous media, produced by stimulating either indigenous bacteria or artificially introduced microbes, readily blocks pore throats and can effectively reduce bulk permeability. Such a microbial clogging treatment can be used for selective plugging of permeable zones in reservoirs and is considered a potentially promising approach to enhance sweep efficiency for microbial enhanced oil recovery (MEOR). Monitoring in situ microbial growth, biopolymer formation, and permeability reduction in the reservoir is critical for successful application of this MEOR approach. We examined the feasibility of using seismic signatures (P-wave velocity and attenuation) for monitoring the in situ accumulation of insoluble biopolymers in unconsolidated sediments. Column experiments, which involved stimulating the sucrose metabolism of Leuconostoc mesenteroides and production of the biopolymer dextran, were performed while monitoring changes in permeability and seismic response using the ultrasonic pulse transmission method. We observed that L. mesenteroides produced a viscous biopolymer in sucrose-rich media. Accumulated dextran, occupying 4%-6% pore volume after similar to 20 days of growth, reduced permeability more than one order of magnitude. A negligible change in P-wave velocity was observed, indicating no or minimal change in compressive stiffness of the unconsolidated sediment during biopolymer formation. The amplitude of the P-wave signals decreased similar to 80% after similar to 20 days of biopolymer production; spectral ratio analysis in the 0.4-0.8-MHz band showed an approximate 30%-50% increase in P-wave attenuation (1/Q(P)) due to biopolymer production. A flow-induced loss mechanism related to the combined grain/biopolymer structure appeared to be the most plausible mechanism for causing the observed increase in P-wave attenuation in the ultrasonic frequency range. Because permeability reduction is also closely linked to biopolymer volume, P-wave attenuation in the ultrasonic frequency range appears to be an effective indicator for monitoring in situ biopolymer accumulation and permeability reduction and could provide a useful proxy for regions with altered transport properties.

Recently developed double-difference elastic-waveform inversion has the potential to quantitatively monitor reservoirs using seismic reflection data. Because the approximate location of a reservoir or a target monitoring region is usually known, we incorporated this knowledge as prior information into double-difference elastic-waveform inversion. Using numerical examples of synthetic time-lapse models, we found that our new method can quantitatively monitor the changes of elastic properties within reservoirs. Therefore, the double-difference elastic-waveform inversion with prior information on the location of a monitoring region is a promising tool for quantitatively monitoring reservoir properties' changes.

In this study, the meteorological conditions and a historical perspective of the winter droughts in western Nepal were analyzed using instrumental records, satellite observations, and climate model simulations. Meteorological diagnosis using atmospheric reanalysis revealed that 1) winter drought in western Nepal is linked to the Arctic Oscillation and its decadal variability, which initiates a tropospheric short-wave train across Eurasia and South Asia; and that 2) the persistent warming of the Indian Ocean likely contributes to the suppression of rainfall through enhanced local Hadley circulation. Simulations from the phase 5 of the Coupled Model Intercomparison Project (CMIP5) sets of historical single-forcing experiments indicated that the increased loading of anthropogenic aerosols is also a compounding factor in the precipitation decline during the later decades. It is therefore conceivable that the recent spells of decadal drought in Nepal are symptomatic of both natural variability and anthropogenic influences. Given the observations that winter precipitation has declined to near zero while groundwater has hardly been replenished, appropriate management of western Nepal's water resources is both critical and necessary.

TI Long-Term Behavior of the Atlantic Interhemispheric SST Gradient in the CMIP5 Historical Simulations SO JOURNAL OF CLIMATE LA English DT Article DE Atlantic Ocean; Atmosphere-ocean interaction; Climate variability; Coupled models; Multidecadal variability; Trends ID SEA-SURFACE TEMPERATURE; TROPICAL ATLANTIC; NORTHEAST BRAZIL; CLIMATE-CHANGE; CIRCULATION; AEROSOL; VARIABILITY; DYNAMICS; PACIFIC; TRENDS AB Multidecadal and longer changes to the Atlantic interhemispheric sea surface temperature gradient (AITG) in phase 5 of the Coupled Model Intercomparison Project (CMIP5) historical simulations are investigated. Observations show a secular trend to this gradient over most of the twentieth century, with the southern lobe warming faster relative to its northern counterpart. A previous study of phase 3 of the CMIP (CMIP3) suggests that this trend is partially forced by anthropogenic sulfate aerosols. This analysis collectively confirms the partially forced trend for the CMIP5 and by anthropogenic aerosols. Like the CMIP3, the CMIP5 also simulates a reversal in the AITG trend in the late 1970s, which was attributed to a leveling off of the anthropogenic aerosol influence and increased influence of greenhouse gases in the late twentieth century. Two (of 25) CMIP5 models, however, systematically simulate a twentieth-century trend opposite to observed, leading to some uncertainty regarding the forced nature of the AITG trend. The observed AITG also exhibits a pronounced multidecadal modulation on top of the trend, associated with the Atlantic multidecadal oscillation (AMO). Motivated by a recent suggestion that the AMO is a forced response to aerosols, the causes of this multidecadal behavior were also examined. A few of the CMIP5 models analyzed do produce multidecadal AITG variations that are correlated to the observed AMO-like variation, but only one, the Hadley Centre Global Environmental Model, version 2 (HadGEM2), systematically simulates AMO-like behavior with both the requisite amplitude and phase. The CMIP5 simulations thus point to a robust aerosol influence on the historical AITG trend but not to the AMO-like multidecadal behavior. C1 [Chiang, John C.

Recently, experiments in seawater enclosures (mesocosms) showed that concentrations of dimethylsulphide (DMS), a biogenic sulphur compound, were markedly lower in a low-pH (e)nvironment4. Marine DMS emissions are the largest natural source of atmospheric sulphur(5) and changes in their strength have the potential to alter the Earth's radiation budget(6). Here we establish observational-based relationships between pH changes and DMS concentrations to estimate changes in future DMS emissions with Earth system model(7) climate simulations. Global DMS emissions decrease by about 18(+/-3)% in 2100 compared with pre-industrial times as a result of the combined effects of ocean acidification and climate change. The reduced DMS emissions induce a significant additional radiative forcing, of which 83% is attributed to the impact of ocean acidification, tantamount to an equilibrium temperature response between 0.23 and 0.48 K. Our results indicate that ocean acidification has the potential to exacerbate anthropogenic warming through a mechanism that is not considered at present in projections of future climate change.

CheW is a scaffold protein that mediates the association of the chemoreceptors and the CheA kinase in a ternary signaling complex. The effects of replacing conserved Arg62 of CheW with other residues suggested that the scaffold protein plays a more complex role than simply binding its partner proteins. Although R62A CheW had essentially the same affinity for chemoreceptors and CheA, cells expressing the mutant protein are impaired in chemotaxis. Using a combination of molecular dynamics simulations (MD), NMR spectroscopy, and circular dichroism (CD), we addressed the role of Arg62. Here we show that Arg62 forms a salt bridge with another highly conserved residue, Glu38. Although this interaction is unimportant for overall protein stability, it is essential to maintain the correct alignment of the chemoreceptor and kinase binding sites of CheW. Computational and experimental data suggest that the role of the salt bridge in maintaining the alignment of the two partner binding sites is fundamental to the function of the signaling complex but not to its assembly. We conclude that a key feature of CheW is to maintain the specific geometry between the two interaction sites required for its function as a scaffold.

TI Bidding behaviors in duopoly electricity markets with aspirant market share goals SO SIMULATION-TRANSACTIONS OF THE SOCIETY FOR MODELING AND SIMULATION INTERNATIONAL LA English DT Article DE Bidding behavior; agent-based simulation; electricity market; collusive behavior; price war; cyclical pricing dynamics ID SPOT MARKET; POWER; INDUSTRY; ENGLAND; WALES; COMPETITION; EFFICIENCY; OLIGOPOLY; COLLUSION; PRICE AB The deregulation and restructuring of electricity markets have created a variety of challenging research problems. In addition, due to the complexity of electricity markets, most of these research problems are not amenable to analytical methods. Agent-based simulation is an approach for simulating and analyzing complex systems with interacting autonomous agents. In this paper, we use an agent-based approach to study the following emergent problem related to electricity market share and competition: what happens if a market participant tries to reach the following two (sometimes conflicting) goals simultaneously, (1) reaching an aspirant market share goal and (2) maximizing profit? More interestingly, what happens if two such participants are competing with each other? The developed agent-based model allows us to examine how the market share goal and profit maximization goal together influence the bidding behaviors of generation companies (i.e. agents) in a day-ahead electricity auction market. It also reveals that conservative market share goals often lead to a collusive behavior and profit maximization. However, if every participant has an aggressive market-share goal, a price war would result. On the other hand, if agents bear unequal market-share goals (e.g. one aggressive and one conservative), one agent will become more profitable than the other. As a result, if both agents want to maximize profit, they will both bid aggressively, resulting in a price war. Therefore, the agent-based model produces results that may explain some real-world pricing outcomes. In addition, to benchmark our agent-based model and to demonstrate the effect of the market-share goal, we develop an analytical model without the market-share goal and compare its results with those from the agent-based model.

By approximating an arbitrary flaw size distribution with a segmented power law, an effort is made to extend applicability of the Weibull distribution to arbitrary flaw populations, which explains why the Weibull distribution fits the experimental data of CNTs and many other brittle materials, and why in other cases it is not so clear. A generalized Weibull distribution is proposed to account for all non-asymptotic cases. The published CNT testing data are analyzed, and finally a major issue present in existing interpretation of CNT bundle testing data is clarified. C1 [Xu, X.

This model is able to simulate radiation induced chemical segregation and the corresponding phase transformation and nano-structure evolution. Under irradiation by a low-energy ion beam defects (vacancies) are created and accumulate. In a binary crystalline material, AB, studied in this work, these defects are of the two types A and B and diffuse at different rates. These differential diffusivities are sufficient driving mechanisms for the formation of chemically distinct regions with accompany changes in phases and nano-structure. In this work, we present a model that can simulate these changes by treating the differential diffusion of the vacancies of the two components.

The ratio of hydrogen to oxygen has been shown to be highly dependent on geomagnetic activity. To investigate this dependence, we examine the timing of the injection and subsequent evolution of O+ in the ring current during the storm of 6 August 2011 as observed by Two Wide-angle Imaging Neutral-atom Spectrometers (TWINS) instruments. To help interpret magnetospheric evolution using the global O Energetic Neutral Atom (ENA) emission measured by TWINS, we have employed a multidomain modeling of the global magnetosphere using the Space Weather Modeling Framework. TWINS Energetic Neutral Atom (ENA) imagers have the capability to distinguish between H and O emission and thus the major ion constituents of the ring current. Global composition measurements from TWINS spacecraft show intensifications of the oxygen ENA emission and thus an increase in the transport of ionospheric oxygen into the ring current that occur during the main phase of the storm. Both the observations and the simulation suggests that the peak in O ENA emission is correlated with the substorm injections that occurred during this time. The model also shows a very dynamic magnetosphere that allows for loss of oxygen from the Earth-magnetosphere system through plasmoids capable of transporting oxygen down the tail throughout the magnetic storm. This can possibly be a predominant pathway for loss of oxygen from the magnetosphere. C1 [Ilie, R.; Skoug, R. M.; Funsten, H. O.] Los Alamos Natl Lab, Los Alamos, NM USA.

The model is set in a uniform, periodic slab with anisotropic ions and cold electrons. Particle-in-cell simulations with a noise reducing falgorithm show agreement with the linear theory of the mirror instability. Results of nonlinear simulations near marginal stability are presented. Single-mode simulations show saturation due to trapping. Simulations with a spectrum of unstable modes show that the negative magnetic perturbations saturate at a lower amplitude and earlier than the positive magnetic perturbations, which results in the development of peaked saturated structures. The saturation amplitude of negative magnetic perturbations is in agreement with the trapped particle theory, while the saturation amplitude of the positive magnetic perturbations is determined by the local change in the (ratio of perpendicular plasma pressure to magnetic pressure) parameter.

CA ATLAS Tile Calorimeter Community TI Mechanical construction and installation of the ATLAS tile calorimeter SO JOURNAL OF INSTRUMENTATION LA English DT Article DE Detector design and construction technologies and materials; Calorimeters AB This paper summarises the mechanical construction and installation of the Tile Calorimeter for the ATLAS experiment at the Large Hadron Collider in CERN, Switzerland. The Tile Calorimeter is a sampling calorimeter using scintillator as the sensitive detector and steel as the absorber and covers the central region of the ATLAS experiment up to pseudorapidities +/- 1.7. The mechanical construction of the Tile Calorimeter occurred over a period of about 10 years beginning in 1995 with the completion of the Technical Design Report and ending in 2006 with the installation of the final module in the ATLAS cavern. During this period approximately 2600 metric tons of steel were transformed into a laminated structure to form the absorber of the sampling calorimeter. Following instrumentation and testing, which is described elsewhere, the modules were installed in the ATLAS cavern with a remarkable accuracy for a structure of this size and weight.

CA DarkSide Collaboration TI DarkSide search for dark matter SO JOURNAL OF INSTRUMENTATION LA English DT Article; Proceedings Paper CT Conference on Light Detection in Noble Elements (LIDINE) CY MAY 29-31, 2013 CL Fermi Natl Accelerator Lab, IL HO Fermi Natl Accelerator Lab DE Noble liquid detectors (scintillation, ionization, double-phase); Dark Matter detectors (WIMPs, axions, etc.) AB The DarkSide staged program utilizes a two-phase time projection chamber (TPC) with liquid argon as the target material for the scattering of dark matter particles. Efficient background reduction is achieved using low radioactivity underground argon as well as several experimental handles such as pulse shape, ratio of ionization over scintillation signal, 3D event reconstruction, and active neutron and muon vetos. The DarkSide-10 prototype detector has proven high scintillation light yield, which is a particularly important parameter as it sets the energy threshold for the pulse shape discrimination technique. The DarkSide-50 detector system, currently in commissioning phase at the Gran Sasso Underground Laboratory, will reach a sensitivity to dark matter spin-independent scattering cross section of 10(-45) cm(2) within 3 years of operation.

TI Assembly and Installation of the Daya Bay Antineutrino Detectors SO JOURNAL OF INSTRUMENTATION LA English DT Article DE Large detector systems for particle and astroparticle physics; Neutrino detectors; Detector alignment and calibration methods (lasers, sources, particle-beams) AB The Daya Bay reactor antineutrino experiment is designed to make a precision measurement of the neutrino mixing angle theta(13), and recently made the definitive discovery of its non-zero value. It utilizes a set of eight, functionally identical antineutrino detectors to measure the reactor flux and spectrum at baselines of similar to 300-2000 m from the Daya Bay and Ling Ao Nuclear Power Plants. The Daya Bay antineutrino detectors were built in an above-ground facility and deployed side-by-side at three underground experimental sites near and far from the nuclear reactors. This configuration allows the experiment to make a precision measurement of reactor antineutrino disappearance over km-long baselines and reduces relative systematic uncertainties between detectors and nuclear reactors. This paper describes the assembly and installation of the Daya Bay antineutrino detectors. C1 [Band, H. R.; Heeger, K. M.; Hinrichs, P.; Lewis, C. A.; Littlejohn, B. R.; McFarlane, M.

CA CMS Collaboration TI The performance of the CMS muon detector in proton-proton collisions at root s=7 TeV at the LHC SO JOURNAL OF INSTRUMENTATION LA English DT Article DE Muon spectrometers; Particle tracking detectors; Particle tracking detectors (Gaseous detectors) ID RESISTIVE PLATE CHAMBERS; BEAM TEST; TRIGGER; LOCALIZATION; SIMULATION; MWPC AB The performance of all subsystems of the CMS muon detector has been studied by using a sample of proton-proton collision data at root s = 7TeV collected at the LHC in 2010 that corresponds to an integrated luminosity of approximately 40 pb(-1). The measured distributions of the major operational parameters of the drift tube (DT), cathode strip chamber (CSC), and resistive plate chamber (RPC) systems met the design specifications. The spatial resolution per chamber was 80-120 mu m in the DTs, 40-150 mu m in the CSCs, and 0.8-1.2 cm in the RPCs. The time resolution achievable was 3 ns or better per chamber for all 3 systems. The efficiency for reconstructing hits and track segments originating from muons traversing the muon chambers was in the range 95-98%. The CSC and DT systems provided muon track segments for the CMS trigger with over 96% efficiency, and identified the correct triggering bunch crossing in over 99.5% of such events. The measured performance is well reproduced by Monte Carlo simulation of the muon system down to the level of individual channel response. The results confirm the high efficiency of the muon system, the robustness of the design against hardware failures, and its effectiveness in the discrimination of backgrounds.

Proper laser beam path and optics arrangement permits profiles T-e(R) and n(e)(R) measurement along the major radius R. Keeping proper alignment between the laser beam path and the collection optics is necessary for an accurate determination of the electron density. As time progresses the relative position of the collection optics field of view with respect to the laser beam path will invariably shift. This can be kept to a minimum by proper attention to the physical arrangement of the collection and laser-beam delivery optics. A system has been in place to monitor the relative position between laser beam and collection optics. Variation of the alignment can be detected before it begins to affect the quality of the profile data. This paper discusses details of the instrumentation and techniques used to maintain alignment during NSTX multi-month experimental campaigns. C1 [LeBlanc, B.

From pixel-based processing designed for low spatial resolution data, image processing has shifted towards object-based analysis in order to adapt to the hyperspatial nature of currently available remote sensing data. However, standard object-based classifiers work with only object-level summary statistics of the reflectance values and do not sufficiently exploit within-object reflectance pattern. In this research, a novel approach of utilizing the object-level distribution of reflectance values is presented. A fuzzy Kolmogorov-Smirnov based classifier is proposed to provide an object-to-object matching of the empirical distribution of the reflectance values of each object and derive a fuzzy membership grade to each class. This object- based classifier is tested for urban objects recognition from WorldView-2 data. Results indicate at least 10 percent increase in overall classification accuracy using the proposed classifier in comparison to various popular object- and pixel-based classifiers.

Xu, Wencan TI The external Q factor of a dual-feed coupling for superconducting radio frequency cavities: Theoretical and experimental studies SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article AB We propose a theoretical model based on network analysis to study the external quality factor (Q factor) of dual-feed coupling for superconducting radio-frequency (SRF) cavities. Specifically, we apply our model to the dual-feed 704 MHz half-cell SRF gun for Brookhaven National Laboratory's prototype Energy Recovery Linac (ERL). The calculations show that the external Q factor of this dual-feed system is adjustable from 10(4) to 10(9) provided that the adjustment range of a phase shifter covers 0 degrees-360 degrees. With a period of 360 degrees, the external Q factor of the coupling system changes periodically with the phase difference between the two coupling arms. When the RF phase of both coupling arms is adjusted simultaneously in the same direction, the external Q factor of the system also changes periodically, but with a period of 180 degrees.

TI Invited Review Article: Methods for imaging weak-phase objects in electron microscopy SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Review ID PARTICLE CRYO-EM; CRYOELECTRON MICROSCOPY; TOPOGRAPHICAL CONTRAST; BIOLOGICAL SAMPLES; 26S PROTEASOME; VORTEX BEAMS; PLATE; RESOLUTION; TEM; CRYOMICROSCOPY AB Contrast has traditionally been produced in electron-microscopy of weak phase objects by simply defocusing the objective lens. There now is renewed interest, however, in using devices that apply a uniform quarter-wave phase shift to the scattered electrons relative to the unscattered beam, or that generate in-focus image contrast in some other way. Renewed activity in making an electron-optical equivalent of the familiar "phase-contrast" light microscope is based in part on the improved possibilities that are now available for device microfabrication. There is also a better understanding that it is important to take full advantage of contrast that can be had at low spatial frequency when imaging large, macromolecular objects. In addition, a number of conceptually new phase-plate designs have been proposed, thus increasing the number of options that are available for development. The advantages, disadvantages, and current status of each of these options is now compared and contrasted. Experimental results that are, indeed, superior to what can be accomplished with defocus-based phase contrast have been obtained recently with two different designs of phase-contrast aperture. Nevertheless, extensive work also has shown that fabrication of such devices is inconsistent, and that their working lifetime is short. The main limitation, in fact, appears to be electrostatic charging of any device that is placed into the electron diffraction pattern. The challenge in fabricating phase plates that are practical to use for routine work in electron microscopy thus may be more in the area of materials science than in the area of electron optics.

The reaction can be carried out at a total pressure up to 1 atm, a regime that has not been accessible to comparable in situ techniques and thus closes the pressure gap to many industrial standard conditions. Two alternate catalyst geometries were tested: (A) a thin film evaporated directly onto an x-ray transparent membrane with a flowing reaction gas mixture behind it or (B) a powder placed behind both the membrane and a gap of flowing reaction gas mixture. To illustrate the working principle and feasibility of our reaction cell setup we have chosen ethylene epoxidation over a silver catalyst as a test case. The evolution of incorporated oxygen species was monitored by total electron/fluorescence yield O K-XAS as well as O K-RIXS, which is a powerful method to separate contributions from inequivalent sites. We find that our method can reliably detect transient species that exist during catalytic reaction conditions that are hardly accessible using other spectroscopic methods.

The primary optical signature used in this redshift range comes from the [OII] emission line doublet, which provides a unique redshift identification that can minimize confusion with other single emission lines. To derive the required spectrograph resolution for these redshift surveys, we simulate observations of the [OII] (lambda lambda 3727, 3729) doublet for various instrument resolutions, and line velocities. We foresee two strategies for the choice of the resolution for future spectrographs for BAO surveys. For bright [OII] emitter surveys ([OII] flux similar to 30 x 10(-17) erg cm(-2) s(-1) like SDSS-IV/eBOSS), a resolution of R similar to 3300 allows the separation of 90 percent of the doublets. The impact of the sky lines on the completeness in redshift is less than 6 percent. For faint [OII] emitter surveys ([OII] flux similar to 10 x 10(-17) erg cm(-2) s(-1) like DESi), the detection improves continuously with resolution, so we recommend the highest possible resolution, the limit being given by the number of pixels (4k by 4k) on the detector and the number of spectroscopic channels (2 or 3).

TI The one-dimensional Ly alpha forest power spectrum from BOSS SO ASTRONOMY & ASTROPHYSICS LA English DT Article DE cosmology: observations; large-scale structure of Universe; intergalactic medium; cosmological parameters ID DIGITAL SKY SURVEY; OSCILLATION SPECTROSCOPIC SURVEY; PROBABILITY-DISTRIBUTION FUNCTION; COLUMN DENSITY DISTRIBUTION; QUASAR TARGET SELECTION; QSO ABSORPTION-SPECTRA; 9TH DATA RELEASE; SDSS-III; INTERGALACTIC MEDIUM; TRANSMITTED FLUX AB We have developed two independent methods for measuring the one-dimensional power spectrum of the transmitted flux in the Lyman-alpha forest. The first method is based on a Fourier transform and the second on a maximum-likelihood estimator. The two methods are independent and have different systematic uncertainties. Determination of the noise level in the data spectra was subject to a new treatment, because of its significant impact on the derived power spectrum. We applied the two methods to 13 821 quasar spectra from SDSS-III/BOSS DR9 selected from a larger sample of over 60 000 spectra on the basis of their high quality, high signal-to-noise ratio (S/N), and good spectral resolution. The power spectra measured using either approach are in good agreement over all twelve redshift bins from < z > = 2.2 to < z > = 4.4, and scales from 0.001 km s(-1) to 0.02 km s(-1). We determined the methodological and instrumental systematic uncertainties of our measurements. We provide a preliminary cosmological interpretation of our measurements using available hydrodynamical simulations. The improvement in precision over previously published results from SDSS is a factor 2-3 for constraints on relevant cosmological parameters. For a ACDM model and using a constraint on H-0 that encompasses measurements based on the local distance ladder and on CMB anisotropies, we infer sigma(8) = 0.83 +/- 0.03 and n(s) = 0.97 +/- 0.02 based on HI absorption in the range 2.1 < z < 3.7.

TI Electrolyte additive combinations that enhance performance of high-capacity Li1.2Ni0.15Mn0.55Co0.1O2-graphite cells SO ELECTROCHIMICA ACTA LA English DT Article DE Electrolyte additives; High voltage; Lithium ion; Calendar life; Additive combinations ID LITHIUM-ION BATTERIES; GRAPHITE-ELECTRODES; POSITIVE ELECTRODE; CATHODE MATERIALS; HIGH-POWER; LIBOB; SALT; INHIBITION AB The synergistic effects of LiB(C2O4)(2) (LiBOB), LiF2B(C2O4) (LiDFOB), triphenylamine (Ph3N), and 1,4-benzodiozane-6,7-diol (BDOD) as functional electrolyte additives in high-energy electrochemical cells is examined. The influence of these additives, individually, and in different combinations, is evaluated using galvanostatic cycling of cells containing Li1.2Ni0.15Mn0.55Co0.1O2 (0.5Li(2)MnO(3)center dot 0.5LiMn(0.375)Ni(0.375)Co(0.25)O(2))-based positive electrodes, graphite-based negative electrodes, and a LiPF6-based electrolyte. Electrochemical impedance spectroscopy (EIS), linear sweep voltammetry (LSV), and voltage-hold tests are also used. By itself, LiBOB is a good additive for reducing cell capacity loss, but cell impedance rise is still significant after extended cycling. Similarly, neither Ph3N nor BDOD alone provide desired improvements in cell performance. However, cells containing LiBOB in combination with LiDFOB, Ph3N, or BDOD exhibit enhanced capacity retention, rate capability, and cyclability; probable reaction mechanisms are highlighted here. Combining electrolyte additives that act synergestically is a practical and versatile strategy to improve performance and life of lithium-ion cells. (C) 2013 Elsevier Ltd. All rights reserved.

TI Preparation and characterization of an alkaline anion exchange membrane from chlorinated poly(propylene) aminated with branched poly(ethyleneimine) SO ELECTROCHIMICA ACTA LA English DT Article DE Anion exchange membrane; Fuel cell; Poly(ethyleneimine); Quaternary ammonium cation; Hydroxide ID FUEL-CELLS; LOW-TEMPERATURE; POLYETHYLENEIMINE; POLYPROPYLENE AB A new randomly crosslinked polymer is investigated for use as an ion-exchange membrane. The polymer was produced through amination of chlorinated poly(propylene) (PP) with poly(ethyleneimine) (PEI) and quaternized with iodoethane. The synthesis of the new polymer is confirmed by FTIR H-1 and C-13 NMR. The microstructure of the polymer consists of aggregates on the order of 1 mu m. Environmentally controlled small and wide angle X-ray analysis showed a relatively featureless amorphous morphology over length scales less than 105 nm through a full range of humidity environments. Little physical swelling of the films were observed, but very high internal water uptake was observed with lambda = 50. The highest in-plane ionic conductivity with chloride as the counter ion observed was 0.29 mS cm(-1) at 90 degrees C and 95% relative humidity. Infrared spectroscopy was used to monitor the relatively rapid rate of counter-ion reaction of hydroxide with ambient CO2 to form a mixture of carbonate and bicarbonate when exposed to air.
