TI A fluid model for ion heating due to ionization in a plasma flow SO PHYSICS OF PLASMAS LA English DT Article ID CUSP MAGNETIC TRAP; MULTICHARGED IONS; COLLISIONLESS; PRESHEATH; DISCHARGE; SHEATH AB A mechanism of ion heating due to local ionization in a plasma flow with hot electrons and initially cold ions is described. It is shown that the ion temperature can increase significantly as the ions are accelerated to the ion-acoustic speed, provided there is significant ionization in the acceleration region. The fluid model describing ionization ion heating includes particle, momentum, and energy balance equations for ion species. Using this model with parameters characteristic of gas-dynamic electron cyclotron resonance (ECR) ion source SMIS 37 yields much higher effective ion temperature than can be attributed to the electron-ion collisional energy transfer, typically considered for classical ECR ion sources. This theoretical result is found to be in agreement with findings of recent experiments carried out in SMIS 37. (c) 2008 American Institute of Physics. C1 [Dorf, M. A.; Semenov, V. E.; Zorin, V.

TI Characterization and investigation of the anomalous behavior of the immersed-B(z) diode during operation at 4 to 5 MV SO PHYSICS OF PLASMAS LA English DT Article ID INTENSE ELECTRON-BEAM; DRIVEN RADIOGRAPHY; MAGNETIC-FIELD; PERFORMANCE; GENERATION; HYDROGEN; DESIGN; IONS; RITS AB The immersed-B(z) diode is being developed as a high-brightness, flash x-ray radiography source at Sandia National Laboratories. This diode is a foil-less electron-beam diode with a long, thin, needlelike cathode which is inserted into the bore of a solenoid. The solenoidal magnetic field guides the electron beam emitted from the cathode to the anode while maintaining a small beam radius. The electron beam strikes a thin, high-atomic-number anode and produces forward-directed bremsstrahlung. In addition, electron beam heating of the anode produces surface plasmas allowing ion emission. Two different operating regimes for this diode have been identified: A nominal operating regime where the total diode current is characterized as classically bipolar with stable impedance [see D. C. Rovang et al., Phys. Plasmas 14, 113107 (2007)] and an anomalous operating regime characterized by a rapid impedance collapse where the total diode current greatly exceeds the bipolar limit. The operating regimes are approximately separated by cathode diameters greater than 3 mm for the nominal regime and less than 3 mm for the anomalous impedance collapse regime. Results from a comprehensive series of experiments conducted at 4-5 MV characterizing the transition from this nominal operating regime to the anomalous operating regime as the cathode diameter is reduced are presented. Results from experiments investigating the effects of anode-cathode gap, anode material, and cryogenic modification of the anode surface are also presented. Although these investigations were unsuccessful in completely mitigating the anomalous behavior, insight gained from these experiments has elucidated several key physics issues that are discussed.

TI The magnetic field structure of a snowflake divertor SO PHYSICS OF PLASMAS LA English DT Article ID SCRAPE-OFF LAYER; X-POINT; DIII-D; TOKAMAK; MODES; EDGE; PERTURBATIONS; TRANSPORT; DYNAMICS; PLASMAS AB The snowflake divertor exploits a tokamak geometry in which the poloidal magnetic field null approaches second order; the name stems from the characteristic hexagonal, snowflakelike shape of the separatrix for an exact second-order null. The proximity of the poloidal field structure to that of a second-order null substantially modifies edge magnetic properties compared to the standard X-point geometry (with a first-order null); this, in turn, affects the edge plasma behavior. Modifications include: (1) The flux expansion near the null-point becomes 2-3 times larger. (2) The connection length between the equatorial plane and divertor plate increases. (3) Magnetic shear just inside the separatrix becomes much larger. (4) In the open-field-line region, the squeezing of the flux-tubes near the null-point increases, thereby causing stronger decoupling of the plasma turbulence in the divertor legs and in the main scrape-off layer. These effects can be used to reduce the power load on the divertor plates and/or to suppress the "bursty" component of the heat flux. It is emphasized that the snowflake divertor can be created by a relatively simple set of poloidal field coils situated outside the toroidal field coils. Analysis of the robustness of the proposed divertor configuration with respect to changes of the plasma current distribution is presented and it is concluded that, even if the null is close to the second order, the configuration is robust.

TI Bright spots in 1 MA X pinches as a function of wire number and material SO PHYSICS OF PLASMAS LA English DT Article ID ENERGY DEPOSITION; SPECTROSCOPY; VACUUM AB Bright, intense x-ray sources with extreme plasma parameters (micropinch plasmas) have previously been characterized at 0.1-0.4 MA, but the scaling of such sources at higher current is poorly understood. The x-ray source size and radiation power of 1 MA X pinches were studied as a function of wire material (Al, Ti, Mo, and W) and number (1-, 2-, 8-, 32-, and 64- wire configurations). The smallest bright spots observed were from 32- wire tungsten X pinches, which produced <= 11-16 mu m, similar to 2 J, 1-10 GW sources of 3-5 keV radiation. (c) 2008 American Institute of Physics.

TI m=1 ideal kink modes in a line-tied screw pinch with finite plasma pressure SO PHYSICS OF PLASMAS LA English DT Article ID CURRENT SHEET FORMATION; CORONAL FLUX TUBES; MAGNETIC-FIELD; SOLAR CORONA; STABILITY; LOOPS; INSTABILITIES; EQUILIBRIA; LENGTH AB A new method for computing ideal magnetohydrodynamic linear eigenmodes in a cylindrical screw pinch with line-tying boundary conditions at the axial ends is presented. In this method, plasma volume is reflected over one of the end planes, and equations and field components are continued into the extended volume with the continuation rules prescribed by the line-tying boundary conditions. Field components in the combined volume are expanded in Fourier series in the axial coordinate. The resulting set of coupled differential equations is solved numerically in the radial coordinate by a finite difference method yielding growth rates and eigenmodes for the system. An example of an m=1 (m is the poloidal wave number) internal kink instability in a force-free plasma equilibrium with uniform pressure is considered. In contrast to a periodic screw pinch, marginally stable perturbations are essentially compressible in the line-tied geometry. Finite compressibility makes the mode more stable in addition to the usual line-tying stabilization in zero pressure plasma. The critical length corresponding to the marginal stability increases with the increase of plasma beta. A universal axial dependence for marginally stable density perturbations rho(r,z) = rho(r)exp[=-iz mu(r)] is predicted analytically and confirmed numerically, where mu(r) depnds on the equilibrium magnetic field components as mu(r)=(B) over bar (theta)/r (B) over bar (z).

It complements existing practices with information regarding what kind of plasma characteristics can be reconstructed, how accurately, and what remains beyond the abilities of diagnostic systems. The sigma-curves, introduced by the present theory, give a quantitative assessment of quality of effectiveness of diagnostic systems in constraining equilibrium reconstructions. The theory also suggests a method for aligning the accuracy of measurements of different physical nature and for improvements of numerical algorithms used in reconstruction.

TI Next generation of elevated [CO2] experiments with crops: a critical investment for feeding the future world SO PLANT CELL AND ENVIRONMENT LA English DT Article DE climate change; crop yield; FACE; genetic variation ID ATMOSPHERIC CARBON-DIOXIDE; OPEN-AIR ELEVATION; CLIMATE-CHANGE; STOMATAL CONDUCTANCE; ENRICHMENT SYSTEM; PHOTOSYNTHESIS; RESPONSES; YIELD; GROWTH; FACE AB A rising global population and demand for protein-rich diets are increasing pressure to maximize agricultural productivity. Rising atmospheric [CO2] is altering global temperature and precipitation patterns, which challenges agricultural productivity. While rising [CO2] provides a unique opportunity to increase the productivity of C-3 crops, average yield stimulation observed to date is well below potential gains. Thus, there is room for improving productivity. However, only a fraction of available germplasm of crops has been tested for CO2 responsiveness. Yield is a complex phenotypic trait determined by the interactions of a genotype with the environment. Selection of promising genotypes and characterization of response mechanisms will only be effective if crop improvement and systems biology approaches are closely linked to production environments, that is, on the farm within major growing regions. Free air CO2 enrichment (FACE) experiments can provide the platform upon which to conduct genetic screening and elucidate the inheritance and mechanisms that underlie genotypic differences in productivity under elevated [CO2]. We propose a new generation of large-scale, low-cost per unit area FACE experiments to identify the most CO2-responsive genotypes and provide starting lines for future breeding programmes. This is necessary if we are to realize the potential for yield gains in the future. C1 [Ainsworth, Elizabeth A.] USDA ARS, Urbana, IL USA.

The G-protein-coupled receptor system integrates signaling cues from the environment to actuate cell morphology, gene expression, ion homeostasis, and other physiological states. We analyze the effects of the two signaling molecules complement factors 5a (C5a) and uridine diphosphate (UDP) on the intracellular second messenger calcium to elucidate the principles that govern the processing of multiple signals by GPCRs. We have developed a formal hypothesis, in the form of a kinetic model, for the mechanism of action of this GPCR signal transduction system using data obtained from RAW264.7 macrophage cells. Bayesian statistical methods are employed to represent uncertainty in both data and model parameters and formally tie the model to experimental data. When the model is also used as a tool in the design of experiments, it predicts a synergistic region in the calcium peak height dose response that results when cells are simultaneously stimulated by C5a and UDP. An analysis of the model reveals a potential mechanism for crosstalk between the G alpha i-coupled C5a receptor and the G alpha q-coupled UDP receptor signaling systems that results in synergistic calcium release.

To illustrate the problem, we have undertaken a genomewide analysis of interactions of members of the PE and PPE protein families of Mycobacterium tuberculosis. Our computational method uses structural information, operon organization, and protein coevolution to infer the interaction of PE and PPE proteins. Some 289 PE/PPE complexes were predicted out of a possible 5,590 PE/PPE pairs genomewide. Thirty-five of these predicted complexes were also found to have correlated mRNA expression, providing additional evidence for these interactions. We show that our method is applicable to other protein families, by analyzing interactions of the Esx family of proteins. Our resulting set of predictions is a starting point for genomewide experimental interaction screens of the PE and PPE families, and our method may be generally useful for detecting interactions of proteins within families having many paralogs.

The Centers for Disease Control and Prevention (CDC)has declared them as Category A biowarfare agents. The most potent among them, botulinum neurotoxin type A (BoNT/A), cleaves its substrate synaptosome-associated protein of 25 kDa (SNAP-25). An efficient drug for botulism can be developed only with the knowledge of interactions between the substrate and enzyme at the active site. Here, we report the crystal structures of the catalytic domain of BoNT/A with its uncleavable SNAP-25 peptide (197)QRATKM(202) and its variant (197)RRATKM(202) to 1.5 angstrom and 1.6 angstrom, respectively. This is the first time the structure of an uncleavable substrate bound to an active botulinum neurotoxin is reported and it has helped in unequivocally defining S1 to S5 ' sites. These substrate peptides make interactions with the enzyme predominantly by the residues from 160, 200, 250 and 370 loops. Most notably, the amino nitrogen and carbonyl oxygen of P1 residue (Gln197) chelate the zinc ion and replace the nucleophilic water. The P1 '-Arg198, occupies the S1 ' site formed by Arg363, Thr220, Asp370, Thr215, Ile161, Phe163 and Phe194. The S2 ' subsite is formed by Arg363, Asn368 and Asp370, while S3 ' subsite is formed by Tyr251, Leu256, Val258, Tyr366, Phe369 and Asn388. P4 '-Lys201 makes hydrogen bond with Gln162. P5 '-Met202 binds in the hydrophobic pocket formed by the residues from the 250 and 200 loop. Knowledge of interactions between the enzyme and substrate peptide from these complex structures should form the basis for design of potent inhibitors for this neurotoxin.

The extended induction time relative to the unstabilised sample and the initial rate of stabiliser depletion were found to be proportional to the initial stabiliser concentration. Previously published kinetic models, based on the hypothesis that the stabiliser is only consumed by reaction with peroxy radicals and that the stationary state assumption is appropriate, were examined and found insufficient to explain the observations. An improved model was suggested assuming the contribution of a phenol oxygen reaction that results in a competing oxidation of the stabiliser itself Experimental and theoretical arguments in favour of this model refinement are proposed.

This allows us to characterize the strength and durability of various interfaces within many types of photovoltaic (PV) modules. We have used this device to evaluate several parameters in terms of their ability to quantify degradation of interfacial adhesion in weathered PV modules. The usefulness of shear modulus in this regard is marginal. However, peak torque, angle at peak torque, and toughness are very sensitive parameters. Published in 2008 by John Wiley & Sons, Ltd.

Theoretical efficiencies of >60% are described for many approaches, but there is often confusion about "the" theoretical efficiency for a specific structure. The detailed balance approach to calculating theoretical efficiency gives an upper bound that can be independent of material parameters and device design. Other models predict efficiencies that are closer to those that have been achieved. Changing reference spectra and the choice of concentration further complicate comparison of theoretical efficiencies. This paper provides a side-by-side comparison of theoretical efficiencies of multi-junction solar cells calculated with the detailed balance approach and a common one-dimensional-transport model for different spectral and irradiance conditions. Also, historical experimental champion efficiencies are compared with the theoretical efficiencies. Copyright (C) 2008 John Wiley & Sons, Ltd. C1 [Kurtz, Sarah; Myers, Daryl; McMahon, W.

The modeling was homology-based at a very low level of sequence identity (similar to 16%) and involved structural comparison of multiple templates, as well as template-substrate interaction analyses. Transferred nuclear Overhauser and saturation transfer difference experiments were used to characterize the binding of sugars and amino acids to orf38.

The fibril-forming capacity of a protein has been found in recent studies to be determined by a short segment of residues that forms a dual beta-sheet, called a steric zipper, in the spine of the fibril. The question arises as to whether a fibril-forming segment, when inserted within the sequence of a globular protein, will invariably cause the protein to form fibrils. Here we investigate this question by inserting the known fibril-forming segment NNQQNY into the globular enzyme, T7 endonuclease I. From earlier studies, we know that in its fibril form, NNQQNY is in an extended conformation. We first found that the inserted NNQQNY stimulates fibril formation of T7 endonuclease I in solution. Thus NNQQNY within T7 endonuclease I can exist in an extended conformation, capable of forming the steric zipper in the core of a fibril. We also found that T7 endonuclease I folds into a decamer that does not form fibrils. We determined the structure of the decamer by X-ray crystallography, finding an unusual oligomer without point group symmetry, and finding that the NNQQNY segments within the decamer adopt two twisted conformations, neither is apparently able to fibrillize. We conclude that twisting of fibril forming sequences from the fully extended conformation, imposed by the context of their placement in proteins, can interfere with fibril formation.

Results in the controls revealed sensitivity to money as measured with P300 amplitude and speed of behavioral response and their intercorrelations. In contrast, despite generally faster P300 waveforms and higher self-reported interest in the task, individuals with CUD did not display these responses to money versus nonreward; at the behavioral level, this impairment correlated with frequency of recent cocaine use. These preliminary results suggest a compromised sensitivity to a secondary reinforcer in CUD. This deficit, which needs to be replicated in larger samples of people with currently active versus abstaining CUD, may underlie the compromised ability to advantageously modify behavior in response to changing inner motivations and environmental contingencies.

TI UNCERTAINTIES IN INTERNAL DOSES CALCULATED FOR MAYAK WORKERS-A STUDY OF 63 CASES SO RADIATION PROTECTION DOSIMETRY LA English DT Article ID PRODUCTION-ASSOCIATION; LIKELIHOOD FUNCTIONS; UNITED-STATES; PLUTONIUM; DOSIMETRY; MODEL AB This study makes use of 63 cases of Mayak workers exposed to Pu-239 with autopsy data and some late-time urine bioassay data. In addition, air-concentration data-used to construct monthly average values-are available for each case, which provide the time dependence and potential magnitudes of normal inhalation intakes for each case. The purpose of the study is to develop and test Bayesian methods of dose calculation for the Mayak workers. The first part of the study was to quantitatively characterise the uncertainties of the bioassay data. Then, starting with three different published biokinetic models, the data are fit by varying intake and model perturbation parameters, e. g., parameters influencing the lung, thoracic lymph nodes, liver and bone retention. Statistical self-consistency arguments are used to check the measurement uncertainty parameters within the Poisson-lognormal model. The second part of the study is to set up and test Bayesian dose calculations, which use the point determinations of biokinetic parameters from the study cases within a discrete, empirical Bayes approximation. The main conclusion of the study is that these methods are now ready to be applied to the entire Mayak worker population.

The discrete empirical Bayes approximation replaces integration over biokinetic model parameters by discrete summation in the evaluation of Bayesian posterior averages using Bayes theorem. The discrete choices of parameters are taken as best-fit point determinations of model parameters for a study subpopulation with extensive data. A simple heuristic model is constructed to numerically and theoretically study this approximation. The heuristic example is the measurement of heights of a group of people, say from a photograph where measurement uncertainty is significant. A comparison is made of posterior mean and standard deviation of height after a measurement, (i) using the exact prior describing the distribution of true height in the population and (ii) using the approximate discrete empirical Bayes prior obtained from measurements of some study subpopulation.

The present report presents baseline data on the effects of gamma radiation on neurobehavioral functions in rodents (psychomotor speed, discrimination accuracy and inhibitory control) that are similar to those in humans. Two groups of eight Long-Evans rats were trained to perform a reaction-time task that required them to depress a lever for 1-3 s and to release the lever within 1.5 s of a release stimulus (correct trial) to receive a reward. Releasing the lever prior to the release stimulus (error) terminated the trial. One group was exposed to head-only gamma radiation (5 Gy at a dose rate of 1 Gy/min), while the second group was sham-irradiated using the same anesthesia protocol. The irradiated group showed significant deficits in both performance accuracy (percentage correct scores) and performance reliability (false alarm scores) from I to 4 months after irradiation, indicating clear performance impairments. The increase in false alarm scores is consistent with reduced inhibitory control and a shift toward increased anticipatory responses at the cost of decreased accuracy. The nonirradiated group showed no such changes over the same period. (c) 2008 by Radiation Research Society.

TI Specific ATM-mediated phosphorylation dependent on radiation quality SO RADIATION RESEARCH LA English DT Article ID DOUBLE-STRAND BREAKS; HISTONE H2AX PHOSPHORYLATION; IONIZING-RADIATION; DNA-DAMAGE; CELL-CYCLE; HIGH-LET; TRANSCRIPTION FACTOR; LESION COMPLEXITY; FOCUS FORMATION; REPAIR AB To determine whether the physical differences between high- and low-LET radiation are reflected in the biological responses of exposed cells, we detailed phospho-protein profiles of three proteins functional in radiation repair and signal transduction. Detailing gamma-H2AX, pATF2 Ser(490/498) and pSMC1 Ser(957) kinetics after X-ray and iron-ion exposure also provides a window into understanding the underlying cellular responses. Phosphorylated forms of these proteins have been documented to co-localize at sites of double-strand breaks (DSBs) after low-LET radiation exposures, and two of these phosphorylations, pATF2 and pSMC1, are specifically dependent on ATM. Flow cytometry-based methods were used to quantify total levels of each phospho-protein at various times after irradiation. As expected, we observed a greater induction and persistence in gamma-H2AX after iron-ion (high-LET) exposure compared to X-ray (low-LET) exposure. In contrast, pATF2 and pSMC1 showed markedly lower induction levels after iron-ion exposure compared to equivalent doses of X rays. Quantification of pATF2 and pSMC1 foci revealed fewer cells containing foci and fewer foci per cell after iron-ion compared to X-ray exposure. These findings suggest that ATM responds to DSBs induced by high-LET radiation differently from DSBs induced by low-LET radiation. (c) 2008 by Radiation Research Society.

Resolution approaching 40 mu m was achieved with a typical DESI-MS setup, which is approximately 5 times better than the best resolution reported previously. This improvement was accomplished with careful control of operational parameters (particularly spray tip-to-surface distance, solvent flow rate, and spacing of lane scans). In addition, an appropriately strong analyte/surface interaction and uniform surface texture on the size scale no larger than the desired imaging resolution were required to achieve this resolution. Overall, conditions providing the smallest possible effective desorption/ionization area in the DESI impact plume region and minimizing the analyte redistribution on the surface during analysis led to improved DESI-MS imaging resolution.

Soil cores were taken at 129 locations that were categorized as reforested (field/ bare ground in 1944 and forest in 1.999), disturbed (field/ bare ground in 1944 and 1999), or reference forests (forest in 1944 and 1999). Soil disturbance included historic agriculture (pre-1944) and military training (post-1944). Density in mineral soils exhibited a historic land use legacy effect (reference < reforested < disturbed). Rates of change in bulk density decreased with depth and estimated total times to reach reference forest levels ranged from 83 (0-10 cm) to 165 (3040 cm) years. A land use legacy effect on C stock was apparent in the O-horizon and in 30- to 40-cm soil increment (reference > reforested > disturbed). Soil C stock in all other increments and in particulate organic matter was affected by disturbance; however, no legacy was apparent (reference = reforested > disturbed). For the entire soil profile (O-horizon to 40 cm), rate of C accrual was 28 g m-(2) yr(-1) (1.5%/yr). Nitrogen stocks were affected by disturbance in the O-horizon and 0- to 10-cm increment; however, no legacy effect was detected (reference = reforested > disturbed). Nitrogen accumulated at 0.56 g m(-2) yr(-1) (0.6%/yr) for the entire soil profile. At Fort Benning, soil C and N stocks of reforested stands were similar to those of reference forested stands after approximately 55 years. However, soil bulk density was greater on reforested stands than reference forest stands at 55 years and may require an additional century to reach reference levels.

TI Design and implementation of a 120 GHz tracking interferometer with near diffraction limited focal spot SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID PLASMA-OPENING SWITCH AB The design and implementation of a 120 GHz monostatic tracking interferometer with near diffraction limited focal spot size, used to measure line-averaged plasma density in the source of a plasma opening switch (POS), is described. Physical dimensions of the switch source place an upper limit on the focal spot size. Focusing quasioptics utilize a standard pyramidal horn and a pair of cylindrical lenses that are easily fabricated. The combination of the two cylindrical lenses transforms the asymmetric and approximately Gaussian beam produced by the pyramidal horn into a small focal spot. The circuit utilizes a tracking receiver configuration to track oscillator frequency drifts, which allow for full heterodyne quadrature operation, while avoiding the added complexity of phase or frequency locking of the sources. In order to reduce system noise in the POS pulsed power environment, all sources and amplifiers are battery powered and other noise-reducing techniques are employed. Finally, an improved Gaussian optics design methodology, which tracks the phase center of the Gaussian beam, is proposed. While not critical to this application, this method may yield improvements in systems with short focal lengths. (C) 2008 American Institute of Physics. [DOI: 10.1063/1.2987690] C1 [Devarapalli, N.

The MCP allows an online measurement of the produced ions in every single laser shot. An electromagnet instead of permanent magnets is used that allows the tuning of the magnetic field to adapt the field strength to the analyzed ion species and energy. We describe recent experiments at the 100 TW laser facility at the Laboratoire d'Utilization des Lasers Intenses (LULI) in Palaiseau, France, where we have observed multiple ion species and charge states with ions accelerated up to 5 MeV/u (O(+6)), emitted from the rear surface of a laser-irradiated 50 mu m Au foil. Within the experiment the TP was calibrated for protons and for the first time conversion efficiencies of MeV protons (2-13 MeV) to primary electrons (electrons immediately generated by an ion impact onto a surface) in the MCP are presented.

TI Lateral shearing interferometer for measuring photoinduced refractive index change in As(2)S(3) SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID FRINGE-PATTERN ANALYSIS; FOURIER-TRANSFORM; TOPOGRAPHY; GLASS AB We have built and demonstrated a lateral shearing interferometer as a process engineering and control tool for the fabrication and characterization of direct-laser-written waveguide structures in chalcogenide glasses. Photoinduced change in refractive index of 0.154 +/- 0.002 was measured for as-deposited amorphous As(2)S(3) thin films at 633 nm with an estimated measurement uncertainty of 1.3% for this air-gap interferometer configuration. The simple design of this interferometer can easily be adapted to other wavelengths including mid-and long-wave infrared regions to measure changes in refractive index or material inhomogeneities in transmissive materials.

Extreme ultraviolet (XUV) imaging at 256 and 68 eV energies is used to determine spatially resolved target rear surface temperature patterns by comparing absolute intensities to radiation hydrodynamic modeling.

The wide aspect ratio channel (the width to height ratio is about 15) is completely enclosed in an inert atmosphere to prevent oxidization of the liquid metal. A custom-designed pump reduces entrainment of oxygen, which was found to be a problem with standard centrifugal and gear pumps. Laser Doppler velocimetry experiments characterize velocity profiles of the flow. Various flow constraints mitigate secondary circulation and end effects on the flow. Measurements of the wave propagation characteristics in the liquid metal demonstrate the surfactant effect of surface oxides and the damping of fluctuations by a cross-channel magnetic field.

TI A diaphragmless shock tube for high temperature kinetic studies SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article AB A novel, diaphragmless shock tube (DFST) has been developed for use in high temperature chemical kinetic studies. The design of the apparatus is presented along with performance data that demonstrate the range and reproducibility of reaction conditions that can be generated. The ability to obtain data in the fall off region, confined to much narrower pressure ranges than can be obtained with a conventional shock tube is shown, and results from laser schlieren densitometry experiments on the unimolecular dissociation of phenyl iodide (P(2)=57+/-9 and 122+/-7 torr, T2=1250-1804 K) are presented. These are compared with results similar to those that would be obtained from a classical shock tube and the implications for extrapolation by theoretical methods are discussed. Finally, the use of the DFST with an online mass spectrometer to create reproducible experiments that can be signal averaged to improve signal/noise and the quality of mass peaks is demonstrated; something that is not possible with a conventional shock tube where each experiment has to be considered unique.

TI Influence of Gd and B on solidification behaviour and weldability of Ni-Cr-Mo alloy SO SCIENCE AND TECHNOLOGY OF WELDING AND JOINING LA English DT Article DE Solidification; Solidification cracking; Neutron Absorbing Materials; Differential Thermal Analysis; Weldability Testing ID SUPERALLOYS; METALLURGY; CRACKING; STEEL; WELDS AB The influence of Gd and B on the solidification behaviour and weldability of Ni-Cr-Mo alloy UNS N06455 has been investigated by Varestraint testing, differential thermal analysis and microstructural characterisation. These alloys are currently being developed as structural materials for nuclear criticality control in applications requiring transportation and disposition of spent nuclear fuel owned by the US Department of Energy. The Gd containing alloys were observed to solidify in a manner similar to a binary eutectic system. Solidification initiated with a primary L ->gamma reaction and terminated at similar to 1258 degrees C with a eutectic type L ->gamma+Ni(5)Gd reaction. The solidification cracking susceptibility of the Gd containing alloys reached a maximum at similar to 1 wt-%Gd and decreased with both higher and lower Gd additions. Low cracking susceptibility at Gd concentrations below similar to 1 wt-% was attributed to a relatively small amount of terminal liquid that existed over much of the crack susceptible solid+liquid zone. Low cracking susceptibility at Gd concentrations above,1 wt-% was attributed to a reduced solidification temperature range and backfilling of solidification cracks. The addition of B above the 230 ppm level leads to the formation of an additional eutectic type reaction at similar to 1200 degrees C and the secondary phase within the eutectic type constituent was tentatively identified as Mo(3)B(2). The B containing alloys exhibited a three step solidification reaction sequence consisting of primary L ->gamma solidification, followed by the eutectic type L ->gamma+Ni(5)Gd reaction, followed by the terminal eutectic type L ->gamma+Mo(3)B(2) reaction. Boron additions had a strong, deleterious influence on solidification cracking susceptibility. The high cracking susceptibility was attributed to extension of the crack susceptible solid+liquid zone induced by the additional eutectic type L ->gamma+Mo(3)B(2) reaction and extensive wetting of the grain boundaries by the solute rich liquid. Simple heat flow equations were combined with solidification theory to develop a relation between the fraction liquid f(L) and distance x within the solid+liquid zone. Information on the phenomenology of crack formation in the Varestraint test were coupled with the calculated f(L)-x curves and were shown to provide useful insight into composition-solidification-weldability relations.

Here we report a significant specimen dimensions influence on the tensile behavior of ultrafine-grained Cu: the elongation to failure, post-necking elongation and strain hardening rate all increase with increasing thickness or decreasing gauge length. The thickness effect is caused by the necking geometry and the effect of gauge length originates from the strain definition. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd.

Pseudo one-dimensional nanopillars are grown using comparable electron-beam parameters and a comparison of the vertical and lateral growth rate and the pillar morphology is correlated to the precursor and deposited material parameters. The primary and secondary electrons (type I) are found to dominate the vertical growth rate and the lateral growth rate is dominated by forward and secondary electrons (type II). The resolution and morphology of the nanopillars are affected by the effective electron interaction volume and the resultant surface coverage of the precursor species in the effective electron interaction region. Finally, the simulated results are compared to previously reported experimental results. C1 [Smith, Daryl A.; Rack, Philip D.] Univ Tennessee, Dept Mat Sci & Engn, Knoxville, TN 37996 USA.

Allen TI Nondestructive system for analyzing carbon in the soil SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID INFRARED REFLECTANCE SPECTROSCOPY; INDUCED BREAKDOWN SPECTROSCOPY; CLIMATE; FOREST; VARIABILITY; LIBS AB Carbon is an essential component of life and, in its organic form, plays a pivotal role in the soil's fertility, productivity, and water retention. It is an integral part of the atmospheric-terrestrial C exchange cycle mediated via photosynthesis; furthermore, it emerged recently as a new trading commodity, i.e., "carbon credits." When carefully manipulated, C sequestration by the soil could balance and mitigate anthropogenic CO(2) emissions into the atmosphere char are believed to contribute global warming. The pressing need for assessing the soil's C stocks at local, regional, and global scales, now in the forefront of much research, is considerably hindered by the problems besetting dry-combustion chemical analyses, even with state-of-the-art procedures. To overcome these issues, we developed a new method based on gamma-ray spectroscopy induced by inelastic neutron scattering (INS). The INS method is all in situ, nondestructive, multielemental technique that can be used in stationary or continous-scanning modes of operation. The results from data acquired from all investigated soil mass of a few hundred kilograms to all approximate depth of 30 cm are reported immediately Our initial experiments have demonstrated the feasibility Of Our proposed approach; we obtained a linear response with C concentration and a detection limit between 0.5 and 1% C by weight.

In this study, the physiochemical factors involved in Pb and Cd transport and sorption in soils were examined to determine the Fate of metal pollutants. A series of metal miscible displacement experiments were executed following a full factorial statistical design including five sources of variability: soil (S1 and S2), metal (Pb and Cd), metal initial concentration (C-0), water flux rate (J(w)), and depth (0-4 and 4-8 cm). Temporal moment analysis of the measured breakthrough curves (BTCS) revealed that Cd transport is characterized by larger mass recovery values and lower estimated values of the transport timing-mean travel time (mu) and vertical solute spreading (sigma(2))-than Pb. This indicates the high affinity and retention of Pb in the soil and the high mobility of Cd. On the other hand, the sorption parameters for both Ph and Cd were estimated from a sequential chemical extraction Of the metal retained in the soil column. The effect of the sources of variability oil both transport and sorption parameters were determined. The functional relationship between sorption and transport parameters was also estimated through a linear regression and canonical correlation analysis. physical and chemical nonequilibrium in transport processes were demonstrated by BTC tailing, changing BTC characteristics (mu and sigma(2)) with J(w) and C-0, and semi-irreversible sorption identified by sequential extraction.

The strengths and weaknesses of different measurement methods and tile ability of analytical models to predict aggregate solar cell performance are examined and compared with earlier studies.

TI A permeability model for coal and other fractured, sorptive-elastic media SO SPE JOURNAL LA English DT Article; Proceedings Paper CT 2006 SPE Eastern Regional Meeting CY OCT 11-13, 2006 CL Canton, OH SP Soc Petr Engineers AB This paper describes the derivation of a new equation that can be used to model the permeability behavior of a fractured. sorptive-elastic medium. such as coal, under variable stress conditions. The equation is applicable to confinement pressure schemes commonly used during the collection of permeability data in the laboratory. The model is derived for cubic geometry under biaxial or hydrostatic confining pressures. The model is designed to handle changes in permeability caused by adsorption and desorption of gases onto and from the matrix blocks in fractured media. The model equations can be used to calculate permeability changes caused by the production of methane (CH4) from coal as well as the injection of gases, such as carbon dioxide, for sequestration in coal. Sensitivity analysis of the model found that each of the input variables can have a significant impact on the outcome of the permeability forecast as a function of changing pore pressure, thus, accurate input data are essential. The permeability model also can be used as a tool to determine input parameters for field simulations by curve fitting laboratory-generated permeability data. The new model is compared to two other widely used coal-permeability models using a hypothetical coal with average properties.

In particular, for electric power applications involving rotating machinery, such as large-scale motors and generators, a high critical current, I(c), and a high engineering critical current density, J(E), in applied magnetic fields in the range of 3-5 Tesla (T) at 65 K are required. In addition, exceeding the minimum performance requirements needed for these applications results in a lower fabrication cost, which is regarded as crucial to realize or enable many large-scale bulk applications of HTS materials. Here we report the fabrication of short segments of a potential superconducting wire comprised of a 4 mu m thick YBa(2)Cu(3)O(7-delta) (YBCO) layer on a biaxially textured substrate with a 50% higher Ic and JE than the highest values reported previously. The YBCO film contained columns of self-assembled nanodots of BaZrO(3) (BZO) roughly oriented along the c-axis of YBCO. Although the YBCO film was grown at a high deposition rate, three-dimensional self-assembly of the insulating BZO nanodots still occurred. For all magnetic field orientations, minimum I(c) and J(E) at 65 K, 3 T for the wire were 353 A cm(-1) and 65.4 kA cm(-2), respectively.

TI Proton segregation on a growing ice interface SO SURFACE SCIENCE LA English DT Article DE water; platinum; dissociation; hydronium; free energy; segregation; work function ID WATER ICE; FILMS; IONS; HYDROGEN; PT(111); LAYER AB Hydronium segregates to the surface of H2O (D2O) ice films grown on Pt(111) above 151 K (158 K). This is observed via the voltage that develops across the films, utilizing work function measurements. The dependence of this voltage on the film's thickness is explained by a simple equilibrium model: as the film grows, most of the surface ions migrate so as to remain at the ice-vacuum interface, while a fixed percentage (similar to 0.05%) take the thermodynamically-unfavored route, to become incorporated into the growing bulk ice. This model implies a Delta G of about +0.1 eV for the movement of ions from the ice surface into the bulk ice. (C) 2008 Elsevier B.V. All rights reserved.

Leptin regulates hypothalamic signaling that underlies the motivation to hyperphagia, but the interaction between leptin and cannabinoid signaling is poorly understood. We evaluated the role of cannabinoid I receptors (CB(1)R) in overeating and the effects of food deprivation on CB(1)R in the brain. One-month-old Zucker rats were divided into unrestricted and restricted (fed 70% of unrestricted rats) diet groups and maintained until adulthood (4 months). Levels of relative binding sites of CB(1)R (CB(1)R binding levels) were assessed using [(3)H] SR141716A in vitro autoradiography. These levels were higher (except cerebellum and hypothalamus) at 4 months than at 1 month of age. One month CB(1)R binding levels for most brain regions did not differ between Ob and Lean (Le) rats (except in frontal and cingulate cortices in Le and in the hypothalamus in Ob). Four month Ob rats had higher CB(1)R binding levels than Le in most brain regions and food restriction was associated with higher CB(1)R levels in all brain regions in Ob, but not in Le rats. CB(1)R binding levels increased between adolescence and young adulthood which we believe was influenced by leptin and food availability. The high levels of CB(1)R in Ob rats suggest that leptin's inhibition of food-intake is in part mediated by downregulation of CB(1)R and that leptin interferes with CB(1)R upregulation under food-deprivation conditions. These results are consistent with prior findings showing increased levels of endogenous cannabinoids in the Ob rats corroborating the regulation of cannabinoid signaling by leptin.

Dichloroacetic acid (DCAA) and 2-acrylamido-2-methyl-1 -propanesulfonic acid (AMPSA) are chosen to study the changes in the GPC chromatograms and the UV-vis spectra of the diluted EB/N-methyl-2-pyrrolidinone (NMP) solutions when the acid was added in the solutions. The studies reveal that the organic acids form H-bonds with EB in an anhydrous solution. DCAA tends to form H-bonds with EB through intra-chain interactions whereas AMPSA tends to form H-bonds with EB through inter-chains. The inter-chain interaction among EB and AMPSA molecules results in the formation of clusters, which occupy a larger hydrodynamic volume and give much higher molecular weights than un-clustered EB molecules. Due to a strong affinity of AMPSA, water molecules are localized inside the clusters when water is present in the solution. Therefore, a small amount of water can rapidly initiate EB protonation (H2O/AMPSA molar ratio > 5.0) at ambient conditions. (C) 2008 Elsevier B.V. All rights reserved.

TI A colorimetric chemodosimeter for Pd(II): a method for detecting residual palladium in cross-coupling reactions SO TETRAHEDRON LA English DT Article ID DERIVATIVES; CATALYST; SENSOR; SUZUKI; IONS; HG2+; BOND AB A colorimetric chemodosimeter (SQ1) for the detection of trace palladium salts in cross-coupling reactions mediated by palladium is described. Decolorization of SQ1 is affected by nucleophilic attack of ethanethiol in basic DMSO Solutions. Thiol addition is determined to have an equilibrium constant (K-eq) of 2.9x10(6) M-1, with a large entropic and modest enthalpic driving force. This unusual result is attributed to solvent effects arising from a strong coordinative interaction between DMSO and the parent squaraine. Palladium detection is achieved through thiol scavenging from the SQ1-ethanethiol complex leading to a color 'turn-on' of the parent squaraine. It was found that untreated samples obtained directly from Suzuki couplings showed no response to the assay. However, treatment of the samples with aqueous nitric acid generates a uniform Pd(NO3)(2) species, which gives an appropriate response. 'Naked-eye' detection of Pd(NO3)(2) was estimated to be as low as 0.5 ppm in solution and instrument-based detection was tested as low as 100 ppb. The average error over the working range of the assay was determined to be 7%. Published by Elsevier Ltd.

Small aromatics can be encapsulated in the supramolecular assembly, and the simultaneous encapsulation of multiple species is observed in many cases. The molecular host assembly is able to recognize different substitutional isomers of disubstituted benzenes with ortho substitution leading to the encapsulation of two guests, but meta or para substitution leading to the encapsulation of only one guest. The scope of hydrophobic guest encapsulation is further explored with chiral natural products. Upon encapsulation of chiral molecules into the racemic host, diastereomeric host-guest complexes are formed with observed diastereoselectivities of up to 78:22 in the case of fenchone.

Here, we review the coordinate evolution of cnidarian nematocysts, secretory organelles used for capture of prey, and of minicollagens, proteins constituting the nematocyst capsule. Within the Cnidaria there is an increase in nematocyst complexity from Anthozoa to Medusozoa and a parallel increase in the number and complexity of minicollagen proteins. This complexity is primarily manifest in a diversification of N- and C-terminal cysteine-rich domains (CRDs) involved in minicollagen polymerization. We hypothesize that novel CRD motifs alter minicollagen networks, leading to novel capsule structures and nematocyst types.

A considerable reduction could be achieved by using biofuels from lignocellulosic biomass instead of fossil fuels. One major bottleneck of biofuel production from lignocellulose is the availability of efficient and inexpensive biocatalysts (i.e. alcohol dehydrogenases, cellulases and esterases) that are active and stable at high temperatures and low pH values. Although heterologous gene expression is used effectively to obtain recombinant proteins derived from mesophiles, the production of thermoacidophilic proteins is often unsuccessful. Some of the reasons for this failure and potential solutions for an increased production of novel extremophilic biocatalysts are discussed here.

TI Analysis of Metal Transfer and Correlated influences in Dual-Bypass GMAW of Aluminum SO WELDING JOURNAL LA English DT Article DE Dual-Bypass Gas Metal Arc; Welding (DB-GMAW); Current; Bypass Arcs; Droplet; Base Metal Heat Input; Spray Transfer ID GAS METAL AB Dual-bypass gas metal arc welding (DB-GMAW) is a modified GMAW process. In this novel process, the base metal current is decreased from the melting current by adding two tungsten electrodes to a conventional GMAW system. The resultant bypass arcs change the forces affecting on the droplet, and the resultant metal transfer becomes more desirable. To understand the desirable changes in the metal transfer, this paper applies established theories to analyze the changes in the forces acting on the droplet and the effects of these changes on the metal transfer behaviors. Analysis shows that the bypass arcs and currents lower the critical current needed to achieve the desired spray transfer. Experimental results obtained by a high-speed camera show that the analysis agrees with experimental data.

In this Study, the sample was computationally characterized without a prior assembly step, providing quantitative insights into the taxonomic composition and gene content of the underlying microbial community. Clostridiales from the phylum Firmicutes is the most prevalent phylogenetic order, Methanomicrobiales are dominant among methanogenic archaea. An analysis of Operational Taxonomic Units (OTUs) revealed that the entire microbial community is only partially covered by the sequenced sample, despite that estimates suggest only a moderate overall diversity of the community. Furthermore, the results strongly indicate that archaea related to the genus Methanoculleus, using CO2 as electron acceptor and H-2 as electron donor, are the main producers of methane in the analyzed biogas reactor sample. A phylogenetic analysis of glycosyl hydrolase protein families suggests that Clostridia play an important role in the digestion of polysaccharides and oligosaccharides. Finally, the results unveiled that most of the organisms constituting the sample are still unexplored. (C) 2008 Elsevier B.V. All rights reserved.

The new steels were patterned after the commercial steels, with the objective that the new steels have yield stress and ultimate tensile strength and impact toughness in a Charpy test comparable to or better than the steels they replaced. That objective was achieved in reduced-activation steels developed in Japan, Europe, and the United States. Although tensile and impact toughness of the reduced-activation steels exceed those of the commercial steels they were patterned after, their creep-rupture properties are inferior to some commercial steels they replaced. They are even more inferior to commercial steels developed since the 1980s. In this paper, compositional differences between reduced-activation steels and new commercial steels are examined, and compositions are proposed for development of new-and-improved reduced-activation steels.

TI Oxidation of aluminum alloy cladding for research and test reactor fuel SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article ID CORROSION AB The oxide thicknesses on aluminum alloy cladding were measured for the test plates from irradiation tests RERTR-6 and 7A in the ATR (advanced test reactor). The measured thicknesses were substantially lower than those of test plates with similar power from other reactors available in the literature. The main reason is believed to be due to the lower pH (pH 5.1-5.3) of the primary coolant water in the ATR than in the other reactors (pH 5.9-6.5) for which we have data. An empirical model for oxide film thickness predictions on aluminum alloy used as fuel cladding in the test reactors was developed as a function of irradiation time, temperature, surface heat flux, pH, and coolant flow rate. The applicable ranges of pH and coolant flow rates cover most research and test reactors. The predictions by the new model are in good agreement with the in-pile test data available in the literature as well as with the RERTR test data measured in the ATR. (C) 2008 Elsevier B.V.

TI Thermal history, partial preservation and sampling bias recorded by Stardust cometary grains during their capture SO EARTH AND PLANETARY SCIENCE LETTERS LA English DT Article DE cometary dusts; Stardust; melts; diffusion; thermal history ID X-RAY-MICROANALYSIS; 81P/WILD-2 DUST; IMPACT FEATURES; VISCOSITY; AEROGEL; MELTS; SILICA; JOIN AB The nature and origin of cometary, grains are poorly known. For this reason the first in situ sampling of cometary materials, the Stardust mission, raised considerable expectations. The Stardust spacecraft captured cometary dusts at a relative velocity of 6.1 km/s in a low density silica aerogel medium. Calculations and laboratory experiments on the shock behaviour of aerogel and hypothetical dust-analogue material indicate that an intense but short heating stage (on the order of the microsecond) occurred during the collection; however, results from the preliminary team emphasized that a large fraction of the collected material was deeply affected by the thermal event, indirectly suggesting that the heating was more protracted. Here we constrain its parameters based on diffusion of MgO and SiO2 between a molten cometary dust and the embedding molten aerogel. After the shock, this assemblage stayed at similar to 2100 K for duration of up to 0.1 ms. This timescale is characteristic for friable and fine-grained aggregates whereas consolidated grains were quenched faster. Therefore, a sampling bias occurred during the collection. It may explain the recent finding that preserved cometary grains look more similar to inner solar nebula material than to chondritic porous interplanetary dust particles (CP-IDP). Indeed, CP-IDPs and other primitive materials are friable materials and consequently, they must have been selectively damaged. The strong thermal modification precludes detailed studies of mineralogy, but molten cometary dusts are only partially mixed with aerogel, giving an opportunity to analyze bulk and local compositions of the impacting aggregate fragments.

TI Errors in determination of soil water content using time domain reflectometry caused by soil compaction around waveguides SO WATER RESOURCES RESEARCH LA English DT Article ID RETENTION CURVE; PROBES AB Application of time domain reflectometry (TDR) in soil hydrology often involves the conversion of TDR-measured dielectric permittivity to water content using universal calibration equations (empirical or physically based). Deviations of soil-specific calibrations from the universal calibrations have been noted and are usually attributed to peculiar composition of soil constituents, such as high content of clay and/or organic matter. Although it is recognized that soil disturbance by TDR waveguides may have impact on measurement errors, to our knowledge, there has not been any quantification of this effect. In this paper, we introduce a method that estimates this error by combining two models: one that describes soil compaction around cylindrical objects and another that translates change in bulk density to evolution of soil water retention characteristics. Our analysis indicates that the compaction pattern depends on the mechanical properties of the soil at the time of installation. The relative error in water content measurement depends on the compaction pattern as well as the water content and water retention properties of the soil. Illustrative calculations based on measured soil mechanical and hydrologic properties from the literature indicate that the measurement errors of using a standard three-prong TDR waveguide could be up to 10%. We also show that the error scales linearly with the ratio of rod radius to the interradius spacing. C1 Lawrence Berkeley Natl Lab, Div Earth Sci, Berkeley, CA 94720 USA.

TI The LANS-alpha and Leray turbulence parameterizations in primitive equation ocean modeling SO JOURNAL OF PHYSICS A-MATHEMATICAL AND THEORETICAL LA English DT Article; Proceedings Paper CT Meeting held in Honor of Darryl D Holms on Geometry and Analysis in Physical Systems CY JUL 22-28, 2007 CL Lausanne, SWITZERLAND ID CLIMATE SYSTEM MODEL; GEOSTROPHIC TURBULENCE; NUMERICAL SIMULATIONS; CIRCULATION MODELS; ATLANTIC-OCEAN; ENERGY; STRATIFICATION; 1/10-DEGREES; RESOLUTION; TRANSPORT AB Ocean modeling presents several unique technical challenges: there is a tremendous range of spatial scales; the kinetic energy forcing scale occurs at the Rossby radius of deformation (20-100 km), which is often at or below the grid resolution; and mixing is strongly anisotropic, occurring primarily along nearly horizontal isopycnal surfaces. We present analysis and numerical results to show that the Lagrangian-averaged Navier-Stokes alpha (LANS-alpha) turbulence parameterization and, to a lesser extent, the Leray parameterization are well suited to ocean modeling. LANS-alpha and Leray are fundamentally different from purely dissipative turbulence models in that both LANS-alpha and Leray are more energetic and produce more eddy structure near the gridscale. This is consistent with expectation from linear stability analysis, where it has been shown that these models resolve the process of baroclinic instability on coarser meshes than standard Navier-Stokes. Formulations of LANS-alpha and Leray models for the primitive equations are presented. In an idealized ocean channel domain, LANS-alpha produces turbulence statistics in kinetic energy, eddy kinetic energy and temperature distributions that resemble a doubled-resolution simulation without LANS-alpha. Leray produces qualitatively similar results, but to a lesser degree than LANS-alpha. Finally, the Leray model is tested in a North Atlantic domain with realistic topography and forcing, and produces higher kinetic and eddy kinetic energy than the non-Leray model. C1 [Hecht, M.

This is achieved by introducing double-bracket dissipation into kinetic equations by using an oriented Poisson bracket and employing the moment method to derive continuum equations for the evolution of magnetization and mass density. These continuum equations generalize the Debye-Huckel equations for attracting round particles, and Landau-Lifshitz Gilbert equations for spin waves in magnetized media. The dynamics of self-assembly is investigated as the emergent concentration into singular clumps of aligned particles (orientons) starting from random initial conditions. Finally, the theory is extended to describe the dissipative motion of self-interacting curved filaments.

TI Spectral scaling of the Leray-alpha model for two-dimensional turbulence SO JOURNAL OF PHYSICS A-MATHEMATICAL AND THEORETICAL LA English DT Article; Proceedings Paper CT Meeting held in Honor of Darryl D Holms on Geometry and Analysis in Physical Systems CY JUL 22-28, 2007 CL Lausanne, SWITZERLAND ID CAMASSA-HOLM EQUATIONS; NAVIER-STOKES EQUATIONS; GLOBAL WELL-POSEDNESS; NUMERICAL SIMULATIONS; FLOW AB We present data from high-resolution numerical simulations of the Navier Stokes-alpha and the Leray-a models for two-dimensional turbulence. It was shown previously ( Lunasin et al 2007 J. Turbul. 8 30) that for wavenumbers k such that k alpha >> 1, the energy spectrum of the smoothed velocity field for the two-dimensional Navier-Stokes-alpha (NS-alpha) model scales as k(-7). This result is in agreement with the scaling deduced by dimensional analysis of the flux of the conserved enstrophy using its characteristic time scale. We therefore hypothesize that the spectral scaling of any alpha-model in the sub-alpha spatial scales must depend only on the characteristic time scale and dynamics of the dominant cascading quantity in that regime of scales. The data presented here, from simulations of the two-dimensional Leray-alpha model, confirm our hypothesis. We show that for ka >> 1, the energy spectrum for the two-dimensional Leray-alpha scales as k(-5), as expected by the characteristic time scale for the flux of the conserved enstrophy of the Leray-alpha model. These results lead to our conclusion that the dominant directly cascading quantity of the model equations must determine the scaling of the energy spectrum.

CA XENON10 Collaboration TI Limits on spin-dependent WIMP-nucleon cross sections from the XENON10 experiment SO PHYSICAL REVIEW LETTERS LA English DT Article ID DARK-MATTER SEARCHES; SCATTERING AB XENON10 is an experiment to directly detect weakly interacting massive particles (WIMPs), which may comprise the bulk of the nonbaryonic dark matter in our Universe. We report new results for spin-dependent WIMP-nucleon interactions with Xe-129 and Xe-131 from 58.6 live days of operation at the Laboratori Nazionali del Gran Sasso. Based on the nonobservation of a WIMP signal in 5.4 kg of fiducial liquid xenon mass, we exclude previously unexplored regions in the theoretically allowed parameter space for neutralinos. We also exclude a heavy Majorana neutrino with a mass in the range of similar to 10 GeV/c(2) -2 TeV/c(2) as a dark matter candidate under standard assumptions for its density and distribution in the galactic halo.

TI Length of time's arrow SO PHYSICAL REVIEW LETTERS LA English DT Article ID FREE-ENERGY DIFFERENCES; NONEQUILIBRIUM MEASUREMENTS; FLUCTUATION THEOREM; PROBABILITY; INFORMATION; DIVERGENCE; EQUALITY; SYSTEMS; ENTROPY AB An unresolved problem in physics is how the thermodynamic arrow of time arises from an underlying time reversible dynamics. We contribute to this issue by developing a measure of time-symmetry breaking, and by using the work fluctuation relations, we determine the time asymmetry of recent single molecule RNA unfolding experiments. We define time asymmetry as the Jensen-Shannon divergence between trajectory probability distributions of an experiment and its time-reversed conjugate. Among other interesting properties, the length of time's arrow bounds the average dissipation and determines the difficulty of accurately estimating free energy differences in nonequilibrium experiments.

TI Triple point on the melting curve and polymorphism of nitrogen at high pressure SO PHYSICAL REVIEW LETTERS LA English DT Article ID X-RAY-DIFFRACTION; RAMAN-SPECTROSCOPY; GPA; PHASE; N-2 AB Raman spectra of solid and fluid nitrogen to pressures up to 120 GPa and temperatures up to 2500 K reveal that the melting line exhibits a maximum near 70 GPa, followed by a triple point near 87 GPa, after which the melting temperature rises again. Fluid nitrogen remains molecular over the entire pressure range studied, and there is no sign of a fluid-fluid transition. Solid phases obtained on quenching from the melt above 48 GPa are identical to the recently discovered iota and xi' phases. We find that kinetics plays a major role in the experimentally observed phase changes and account for the metastability of various crystalline molecular phases and the existence of an amorphous single bonded eta - N.

TI Medium-mass nuclei from chiral nucleon-nucleon interactions SO PHYSICAL REVIEW LETTERS LA English DT Article ID COUPLED-CLUSTER APPROACH; 2-NUCLEON SYSTEM; FORCES; LAGRANGIANS; FIELD; O-16 AB We compute the binding energies, radii, and densities for selected medium-mass nuclei within coupled-cluster theory and employ a bare chiral nucleon-nucleon interaction at next-to-next-to-next-to-leading order. We find rather well-converged results in model spaces consisting of 15 oscillator shells, and the doubly magic nuclei Ca-40, Ca-48, and the exotic Ni-48 are underbound by about 1 MeV per nucleon within the coupled-cluster singles-doubles approximation. The binding-energy difference between the mirror nuclei Ca-48 and Ni-48 is close to theoretical mass table evaluations. Our computation of the one-body density matrices and the corresponding natural orbitals and occupation numbers provides a first step to a microscopic foundation of the nuclear shell model.

By directly observing antiferromagnetic spin fluctuations in the paramagnetic phase, we have shown that the characteristic energy depends on temperature as c(1) + c(2)T(3/2), where c(1) and c(2) are constants. This T(3/2) dependence demonstrates that the present strongly correlated d-electron antiferromagnet clearly shows the criticality of the spin-density-wave quantum phase transition in three space dimensions.

For a spin-1 parent the theorem predicts that (1) there are only two possible couplings and (2) the normalized differential cross section depends on kinematics only through a phase shift in the azimuthal angle between the two decay planes of the Z boson. When the parent is a Z' the two possible couplings are anomaly induced and CP violating, respectively. At the CERN Large Hadron Collider their effects could be disentangled when both Z bosons decay leptonically. C1 [Keung, Wai-Yee] Univ Illinois, Dept Phys, Chicago, IL 60607 USA.

Magnetic sublattice precession is coherently excited via picosecond thermal modification of the exchange energy. Importantly, this precession is recorded as a change in reflectance caused by the dynamic magnetoelectric effect. Thus, transient reflectance provides a sensitive probe of magnetization dynamics in materials with strong magnetoelectric coupling, such as multiferroics, revealing new possibilities for application in spintronics and ultrafast manipulation of magnetic moments.

TI Diffraction and IR/Raman data do not prove tetrahedral water SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID RADIAL-DISTRIBUTION FUNCTIONS; RAY-ABSORPTION SPECTROSCOPY; PAIR CORRELATION-FUNCTIONS; HYDROGEN-BOND NETWORK; LIQUID WATER; DILUTE HOD; INFRARED-SPECTROSCOPY; POTENTIAL FUNCTIONS; MOLECULAR-DYNAMICS; PHASE AB We use the reverse Monte Carlo modeling technique to fit two extreme structure models for water to available x-ray and neutron diffraction data in q space as well as to the electric field distribution as a representation of the OH stretch Raman spectrum of dilue HOD in D2O; the internal geometries were fitted to a quantum distribution. Forcing the fit to maximize the number of hydrogen (H) bonds results in a tetrahedral model with 74% double H-bond donors (DD) and 21% single donors (SD). Maximizing instead the number of SD species gives 81% SD and 18% DD, while still reproducing the experimental data and losing only 0.7-1.8 kJ/mole interaction energy. By decomposing the simulated Raman spectrum we can relate the models to the observed ultrafast frequency shifts in recent pump-probe measurements. Within the tetrahedral DD structure model the assumed connection between spectrum position and H-bonding indicates ultrafast dynamics in terms of breaking and reforming H bonds while in the strongly distorted model the observed frequency shifts do not necessarily imply H-bond changes. Both pictures are equally valid based on present diffraction and vibrational experimental data. There is thus no strict proof of tetrahedral water based on these data. We also note that the tetrahedral structure model must, to fit diffraction data, be less structured than most models obtained from molecular dynamics simulations.

Properties are calculated via the GW-Bethe-Salpeter equation and diffusion quantum Monte Carlo methods. We critically compare these theories and assess their accuracy against available photoabsorption and photoelectron spectroscopy data. The first ionization potentials are consistently well reproduced and are similar for all the fullerenes and methods studied. The electron affinities and first triplet excitation energies show substantial method and geometry dependence. These results establish the validity of many-body theories as viable alternative to density-functional theory in describing electronic properties of confined carbon nanostructures. We find a correlation between energy gap and stability of fullerenes. We also find that the electron affinity of fullerenes is very high and size independent, which explains their tendency to form compounds with electron-donor cations.

TI An eight-degree-of-freedom quantum dynamics study of the isotopic effect on the reaction: HD+C(2)H SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID RATE-CONSTANT MEASUREMENTS; TEMPERATURE-DEPENDENCE; C2H; SCATTERING; H-2; PHOTOCHEMISTRY; ACETYLENE; D2; ATMOSPHERE; KINETICS AB An eight-dimensional time-dependent quantum dynamics calculation is reported to study the isotopic reaction, HD+C(2)H, on a new modified potential energy surface. Initial-state-selected reaction probability, integral cross section, and rate constants are presented in this isotopic reaction study. Initial-state-selected reaction probability is obtained by summing over all the possible product's arrangements in this isotopic reaction study. This study shows that vibrational excitations of HD enhance the reactivity, whereas stretching excitations of C(2)H only have a small effect on the reactivity. Furthermore, the bending excitations of C(2)H, compared to the ground-state reaction probability, hinder the reactivity. The present results are consistent with those obtained for the H(2)+C(2)H reaction. The comparison of these two reactions also shows the isotopic effect in the initial-state-selected reaction probability, integral cross section, and rate constants. The rate constant comparison shows that the HD+C(2)H reaction has a smaller reactivity than the H(2)+C(2)H reaction. (c) 2008 American Institute of Physics.

The emphasis in this Article is the geometry of the phase space of the dynamical system describing the steady flames. It is shown that steady flames are described by trajectories on the stable manifolds of saddle fixed points. The saddle fixed points correspond to equilibrium points of time-dependent chemical-kinetic systems that are adiabatic and isobaric and whose constant enthalpy matches the asymptotic enthalpy of the flames. The dimensions of the stable manifolds match the dimensions of the chemical-kinetic systems under most conditions, although the dynamics on them are different. It is further shown that the stable manifolds have low-dimensional attractive submanifolds near the saddlepoint. An algorithm for generating trajectories over the spatial domain of these flames is proposed, and it is used to study individual trajectories and trajectory ensembles, whose collective behavior Suggests that there are low-dimensional submanifolds away from the saddlepoint.

Algorithms for generating low-dimensional manifolds for these systems are presented and used to find low-dimensional manifolds for the flames and the corresponding adiabatic, isobaric chemical-kinetic systems. It is demonstrated that these algorithms generate manifolds that are more accurate than the ILDM algorithm for two-dimensional manifolds of the flames. The manifolds are then employed to study the relationship between the manifolds of the flame and the manifolds of the chemical-kinetic system. It is shown that the one-dimensional manifolds of the flame match well with the composite manifolds of the chemical kinetics, but that for two-dimensional manifolds there are discrepancies between the flame manifolds and the chemical-kinetic manifolds.

Evidence has been found for strong coupling between the electronic ground state and the f-electron manifold which dominates the dynamics of the excited states of the bis(ketimide) uranium complex. These also demonstrate strong singlet-f manifold coupling, which assists in the deactivation of the photoexcited state of the uranium complex, and provide information oil intersystem crossing and internal conversion processes in both complexes.

After carbonization of polypyrrole at 800 degrees C and etching of the silica templates with hydrofluoric acid solution, nitrogen-doped and graphitic OMCs with incorporated magnetic nanoparticles were obtained. These materials were analyzed by CHNS elemental analysis, thermogravimetry (TG), nitrogen adsorption, small and wide angle powder X-ray diffraction (XRD), Raman spectroscopy, scanning, and transmission electron microscopy (TEM). The resulting carbon replicas retained the crystallographic symmetry of the silica templates: namely, P6mm in the case of the SBA-15 template, and Im3m in the case of the SBA-16 template. The uniformity, size, and volume of ordered mesopores in the carbon replicas were affected by structural properties of the templates used as shown by analysis of nitrogen adsorption isotherms and pore size distributions. A better infiltration of carbon precursor was achieved for the templates with larger pores, which resulted in the carbon replicas of improved adsorption and structural properties. Elemental analysis revealed the presence of nitrogen in the carbon replicas studied in the range of 3-8 wt %, whereas TG analysis of the replica samples in air gave about 2-5% residue, which was identified as hematite (Fe2O3). The presence of graphitic domains was confirmed by characteristic TG oxidation profile above 400 degrees C, the D and G bands on the Raman spectra, and the intense reflections on the wide angle XRD patterns. Powder XRD also showed the presence of extra-framework magnetic iron (alpha-Fe) and iron carbide (Fe3C) nanoparticles having crystallite size in the ranges of 40-80 and 20-40 nm, respectively. TEM images also revealed that these nanoparticles were larger than the carbon rods and pore widths of the SBA-15 carbon replica, which is in good agreement with the XRD-based estimation. The in situ EDS analysis of carbon rods and spheres showed that iron was present in the carbonaceous framework, which does not exclude the existence of much smaller nanoparticles, below 5 nm.

TI How cooper pairs vanish approaching the Mott insulator in Bi(2)Sr(2)CaCu(2)O(8+delta) SO NATURE LA English DT Article ID HIGH-TEMPERATURE SUPERCONDUCTORS; QUASI-PARTICLES; PHYSICS; CA2-XNAXCUO2CL2; PSEUDOGAP; EVOLUTION AB The antiferromagnetic ground state of copper oxide Mott insulators is achieved by localizing an electron at each copper atom in real space (r-space). Removing a small fraction of these electrons ( hole doping) transforms this system into a superconducting fluid of delocalized Cooper pairs in momentum space ( k- space). During this transformation, two distinctive classes of electronic excitations appear. At high energies, the mysterious 'pseudogap' excitations are found, whereas, at lower energies, Bogoliubov quasi- particles - the excitations resulting from the breaking of Cooper pairs should exist. To explore this transformation, and to identify the two excitation types, we have imaged the electronic structure of Bi(2)Sr(2)CaCu(2)O(8+delta) in r- space and k- space simultaneously. We find that although the low- energy excitations are indeed Bogoliubov quasi- particles, they occupy only a restricted region of k- space that shrinks rapidly with diminishing hole density. Concomitantly, spectral weight is transferred to higher energy r- space states that lack the characteristics of excitations from delocalized Cooper pairs. Instead, these states break translational and rotational symmetries locally at the atomic scale in an energy- independent way. We demonstrate that these unusual r- space excitations are, in fact, the pseudogap states. Thus, as the Mott insulating state is approached by decreasing the hole density, the delocalized Cooper pairs vanish from k- space, to be replaced by locally translational- and rotational- symmetry- breaking pseudogap states in r- space.

Elucidation of the underlying mechanisms of viral replication is critical for development of anti- influenza virus drugs(2). The influenza RNA- dependent RNA polymerase ( RdRp) heterotrimer has crucial roles in viral RNA replication and transcription. It contains three proteins: PA, PB1 and PB2. PB1 harbours polymerase and endonuclease activities and PB2 is responsible for cap binding(3,4); PA is implicated in RNA replication(5-10) and proteolytic activity(11-14), although its function is less clearly defined. Here we report the 2.9 angstrom structure of avian H5N1 influenza A virus PA ( PA(C), residues 257 - 716) in complex with the PA- binding region of PB1 ( PB1(N), residues 1 - 25). PA(C) has a fold resembling a dragon's head with PB1(N) clamped into its open 'jaws'. PB1(N) is a known inhibitor that blocks assembly of the polymerase heterotrimer and abolishes viral replication. Our structure provides details for the binding of PB1(N) to PA(C) at the atomic level, demonstrating a potential target for novel anti- influenza therapeutics. We also discuss a potential nucleotide binding site and the roles of some known residues involved in polymerase activity. Furthermore, to explore the role of PA in viral replication and transcription, we propose a model for the influenza RdRp heterotrimer by comparing PA(C) with the lambda 3 reovirus polymerase structure, and docking the PA(C) structure into an available low resolution electron microscopy map.

SO PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY A-MATHEMATICAL PHYSICAL AND ENGINEERING SCIENCES LA English DT Article DE phase transitions; quantum phase transitions; topological excitations; avoided level crossing; Landau-Zener tunnelling ID STRING FORMATION; COSMOLOGICAL EXPERIMENTS; DEFECT FORMATION; VORTEX FORMATION; SUPERFLUID HE-3; LIQUID-CRYSTALS; COSMIC STRINGS; QUENCH; GENERATION; MECHANISM AB We extend the theory of symmetry-breaking dynamics in non-equilibrium second-order phase transitions known as the Kibble-Zurek mechanism (KZM) to transitions where the change of phase occurs not in time but in space. This can be due to a time-independent spatial variation of a field that imposes a phase with one symmetry to the left of where it attains critical value, while allowing spontaneous symmetry breaking to the right of that critical borderline. Topological defects need not form in such a situation. We show, however, that the size, in space, of the 'scar' over which the order parameter adjusts as it 'bends' interpolating between the phases with different symmetries follows from a KZM-like approach. As we illustrate on the example of a transverse quantum Ising model, in quantum phase transitions this spatial scale the size of the scar is directly reflected in the energy spectrum of the system: in particular, it determines the size of the energy gap.

It is common, however, to represent the complex fracture by much simpler models consisting of a single fracture, with a uniform or heterogeneous transmissivity distribution over its plane and bounded on both sides by a homogeneous semi-infinite matrix. Simple-model properties are often inferred from the analysis of short-term (one to a few days) site characterization (SC) tracer test data. The question addressed in this paper is: How reliable is the temporal upscaling of these simplified models? Are they adequate for long-term calculations that cover thousands of years? In this study, a particle-tracking approach is used to calculate tracer test breakthrough curves (BTCs) in a complex fracture model, incorporating all the features described above, for both a short-term SC tracer test and a 10,000-year calculation. The results are considered the "real world''. Next, two simple fracture models, one uniform and the other heterogeneous, are introduced. Properties for these simple models are taken either from laboratory data or found by calibration to the short-term SC tracer test BTCs obtained with the complex fracture model. Then the simple models are used to simulate tracer transport at the long-term timescale. Results show that for the short-term SC tracer test, the BTCs calculated using simple models with laboratory-measured parameters differ significantly from the BTCs obtained with the complex fracture model. By adjusting model properties, the simple models can be calibrated to reproduce the peak arrival time and height of the complex fracture model BTCs, but the overall match remains quite poor. Using simple models with short-term SC-calibrated parameters for long-term calculations yields BTCs with order-of-magnitude errors: peak arrival time is 10 to 100 times too late, and peak height is 50 to 300 times too small. On the other hand, using simple models with laboratory-measured properties of unfractured rock samples for 10,000-year calculations yields BTCs with peak arrivals and heights up to a factor of 50 too early and large, respectively. The actual magnitudes of the errors made by using the simple models depend on the parameter values assumed for the complex fracture model, but in general, simple models are not expected to provide reliable long-term predictions. The paper concludes with some suggestions on how to improve long-term prediction calculations.

TI Aqueous and isotope geochemistry of mineral springs along the southern margin of the Tibetan plateau: Implications for fluid sources and regional degassing of CO(2) SO GEOCHEMISTRY GEOPHYSICS GEOSYSTEMS LA English DT Article DE Tibetan plateau; springs; delta(13)C; delta(15)N; (3)He/(4)He; CO(2) flux ID BENEATH CENTRAL TIBET; HIGH HEAT-FLOW; SUBDUCTION ZONES; HIMALAYAN OROGEN; CATALINA SCHIST; EVEREST MASSIF; MIDDLE CRUST; NOBLE-GASES; CARBON; HELIUM AB [1] Springs issuing from different faults and shear zones along the crest of the Himalayas tap three different levels of crust beneath the Tibetan Plateau. From structurally highest to lowest these are the Tingri Graben, the South Tibetan Detachment System (STDS), and the Ama Drime massif (ADM). The aqueous chemistry reflects water-rock interactions along faults and is consistent with mapped rock types. Major ion chemistry and calculated temperatures indicate that spring waters have circulated to greater depths along the N-S trending faults that bound the Tingri Graben and Ama Drime detachment (ADD) compared to the STDS, suggesting that these structures penetrate to greater depths. Springs have excess CO(2), N(2), He, and CH(4) compared to meteoric water values, implying addition from crustal sources. The (3)He/(4)He ratios range from 0.018 to 0.063 RA and are consistent with a crustal source for He. The delta(13)C values of dissolved inorganic carbon (DIC) and CO(2) gas range from -5.5 to + 3.8% and -13.1 to -0.3% versus Peedee belemnite, respectively. Sources of carbon are evaluated by calculating isotopic trajectories associated with near-surface effervescence of CO(2). Positive delta(13)C values of the Tingri graben and STDS springs are consistent with decarbonation of marine carbonates as the source of CO(2). Negative values for the ADD springs overlap with mantle values but are best explained by metamorphic devolatilization of reduced sedimentary carbon. The delta(15)N values of N(2) range from -2.2 to +2.1% ( versus AIR) and are explained by mixtures of air-derived nitrogen, metamorphic devolatilization of sedimentary nitrogen, and nitrogen from near-surface biogenic processes. CO(2) flux is estimated by scaling from individual springs (similar to 10(5) mol a(-1) per spring) to extensional structures across the southern limit of the Tibetan Plateau and likely contributes between 10(8) and 10(11) mol a(-1) (up to 10%) to the global carbon budget.

The derivation is based on the hypothesis that dayside reconnection is governed by local plasma parameters and that whatever controls those parameters controls the reconnection rate. The starting point of the derivation is the Cassak-Shay formula (from energy conservation principles), which expresses the dayside reconnection rate in terms of four parameters: the magnetic field strengths B(m) and B(s) in the magnetosphere and magnetosheath and the plasma mass densities rho(m) and rho(s) in the magnetosphere and magnetosheath. Using the Rankine- Hugoniot relations at the bow shock and an analysis of the magnetosheath flow, three of these parameters are expressed in terms of upstream solar wind parameters. These three expressions are then used in the Cassak- Shay formula to obtain the " solar wind control function.'' The interpretation of the control function is that solar wind pressure largely sets the reconnection rate. The solar wind magnetic field enters into the control function because of a bow shock Mach number dependence. The onset of a " plasmasphere effect'' occurs when rho(m) > MA 0.87r solarwind, wherein the magnetosphere begins to exert control over solar wind/ magnetosphere coupling. Using the OMNI2 data set and seven geomagnetic indices, the solar wind control function is tested on its ability to describe the variance in the geomagnetic indices. The control function is found to be successful, statistically as good as the best " solar wind driver function'' in the literature. This picture opens a new pathway to understanding and calculating solar wind/magnetosphere coupling. C1 Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

To determine the theoretical spectra of Jovian X-ray auroras, we model numerically the collisionally induced evolution of energy and charge distributions of O(q+) and S(q+) ions, precipitating into the Jovian atmosphere. Monte Carlo simulations of the energy and charge relaxation of the precipitating ions are carried out with updated cross-sections of the ion stripping, electron capture, and gas-ionization collisions. X-ray and Extreme Ultraviolet (EUV) spectra of cascading radiation induced by individual energetic sulfur and oxygen ions are calculated, and relative intensities of X-ray emission lines are determined. Synthetic spectra of X-ray and EUV photons are computed at different initial kinetic energies and compositions of ion-precipitating fluxes. Theoretical spectra with adjustable initial energies and relative fraction of sulfur and oxygen ions are shown to be in good agreement with the spectra of X rays detected from the South and North polar regions. The abundances and initial energies of the precipitating ions are inferred by comparing synthetic and observed X-ray spectra. Comparisons are performed independently for the North and South pole emissions. Abundances of the precipitating sulfur ions are found to be four to five times smaller than those of oxygen ions, and averaged ion energies are determined to lie between 1 and 2 MeV/amu. Slightly different ion flux compositions are found to describe the observed spectra of X-ray emission from the North and South poles.

Frei, Heinz TI Visible light-induced electron transfer from di-mu-oxo-bridged dinuclear Mn complexes to Cr centers in silica nanopores SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID OXYGEN-EVOLVING COMPLEX; MIXED-VALENCE INTERACTIONS; PHOTOSYSTEM-II; MANGANESE COMPLEXES; MESOPOROUS SILICA; WATER OXIDATION; TRIS-BIPYRIDINE; CLAY COMPOUNDS; RU-III; CLUSTER AB The compound (bpy)(2)Mn(III)(mu-O)(2)Mn(IV)(bpy)(2), a structural model relevant for the photosynthetic water oxidation complex, was coupled to single Cr(VI) charge-transfer chromophores in the channels of the nanoporous oxide AIMCM-41. Mn K-edge EXAFS spectroscopy confirmed that the di-mu-oxo dinuclear Mn core of the complex is unaffected when loaded into the nanoscale pores. Observation of the 16-line EPR signal characteristic of Mn(III)(mu-O)(2)Mn(IV) demonstrates that the majority of the loaded complexes retained their nascent oxidation state in the presence or absence of Cr(VI) centers. The FT-Raman spectrum upon visible light excitation of the Cr(VI)-O(II) -> Cr(V)-O(I) ligand-to-metal charge transfer reveals electron transfer from Mn(III)(mu-O)(2)Mn(IV) (Mn-O stretch at 700 cm(-1)) to Cr(VI), resulting in the formation of Cr(V) and Mn(IV)(mu-O)(2)Mn(IV) (Mn-O stretch at 645 cm(-1)). All initial and final states are directly observed by FT-Raman or EPR spectroscopy, and the assignments are corroborated by X-ray absorption spectroscopy measurements. The endoergic charge separation products (Delta E(circle) = -0.6 V) remain after several minutes, which points to spatial separation of Cr(V) and Mn(IV)(mu-O)(2)Mn(IV) as a consequence of hole (O(I)) hopping as a major contributing mechanism. This is the first observation of visible light-induced oxidation of a potential water oxidation complex by a metal charge-transfer pump in a nanoporous environment. These findings will allow for the assembly and photochemical characterization of well-defined transition metal molecular units, with the ultimate goal of performing endothermic, multielectron transformations that are coupled to visible light electron pumps in nanostructured scaffolds.

TI Supramolecular catalysis of orthoformate hydrolysis in basic solution: An enzyme-like mechanism SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID HOST-GUEST COMPLEXATION; ASSEMBLED MOLECULAR CAPSULE; DIELS-ALDER REACTION; BETA-CYCLODEXTRIN; BINDING AFFINITIES; ETHYL ORTHOFORMATE; ACID CATALYSIS; PEPTIDE-BOND; PK(A) SHIFTS; WATER AB A water-soluble self-assembled supramolecular host molecule catalyzes the hydrolysis of orthoformates in basic solution. Comparison of the rate constants of the catalyzed and uncatalyzed reactions for hydrolysis displays rate accelerations of up to 3900 for tri-n-propyl orthoformate. Kinetic analysis shows that the mechanism of hydrolysis with the supramolecular host obeys the Michaelis-Menten model. Mechanistic studies, including (13)C-labeling experiments, revealed that the resting state of the catalytic system is the neutral substrate encapsulated in the host. Activation parameters for the k(cat) step of the reaction revealed that upon substrate encapsulation in the assembly, the entropy of activation becomes more negative in contrast to the uncatalyzed reaction. Furthermore, solvent isotope effects reveal a normal k(H(2)O)/k(D(2)O) = 1.6, confirming an A-S(E)2 mechanism in which proton transfer occurs in the rate-limiting step. This is in contrast with the A1 mechanism of the uncatalyzed reaction in which decomposition of the protonated substrate is rate-limiting.

The resulting materials feature a metal/Ge(9) framework perforated by regular arrays of mesoporous channels. The permanent mesoporosity of the materials NU-MGe-2 (M = Sb, In, Sri, Pb, Cd), determined by N(2) physisorption measurements, corresponds to high internal BET surface areas from 127 to 277 m(2)/g and total pore volumes from 0.15 to 0.26 cm(3)/g. The mesoporous structures exhibit energy gaps in the range of 1.48-1.70 eV as well as strong photoluminescence at room temperature with emission energies varying from 740 to 845 rim. The emission depends on pore wall thickness and framework composition. The photoemission intensity in the mesoporous intermetallic germanium-based frameworks can be selectively suppressed by adsorbing electron-acceptor species such as tetracyanoethylene molecules but remains unchanged when exposed to electron-donor species such as tetrathiafulvalene molecules.

TI Second-generation difluorinated cyclooctynes for copper-free click chemistry SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID IN-VIVO; 1,3-DIPOLAR CYCLOADDITIONS; TERMINAL ALKYNES; LIVING SYSTEMS; AZIDES; LIGATION; BIOCONJUGATION; VISUALIZATION; DERIVATIVES; GLYCANS AB The 1,3-dipolar cycloaddition of azides and activated alkynes has been used for site-selective labeling of biomolecules in vitro and in vivo. While copper catalysis has been widely employed to activate terminal alkynes for [3 + 2] cycloaddition, this method, often termed "click chemistry", is currently incompatible with living systems because of the toxicity of the metal. We recently reported a difluorinated cyclooctyne (DIFO) reagent that rapidly reacts with azides in living cells without the need for copper catalysis. Here we report a novel class of DIFO reagents for copper-free click chemistry that are considerably more synthetically tractable. The new analogues maintained the same elevated rates of [3 + 2] cycloaddition as the parent compound and were used for imaging glycans on live cells. These second-gene ration DIFO reagents should expand the use of copper-free click chemistry in the hands of biologists.

TI The siderocalin/enterobactin interaction: A link between mammalian immunity and bacterial iron transport SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID GELATINASE-ASSOCIATED LIPOCALIN; LIGAND-BINDING; ENDOSOMAL MEMBRANES; KIDNEY EPITHELIA; ENTEROBACTIN; RECEPTOR; PROGRAM; COMPLEX; SPECTROSCOPY; INFLAMMATION AB The siderophore enterobactin (Ent) is produced by enteric bacteria to mediate iron uptake. Ent scavenges iron and is taken up by the bacteria as the highly stable ferric complex [Fe(III)(Ent)](3-). This complex is also a specific target of the mammalian innate immune system protein, Siderocalin (Scn), which acts as an antibacterial agent by specifically sequestering siderophores and their ferric complexes during infection. Recent literature suggesting that Scn may also be involved in cellular iron transport has increased the importance of understanding the mechanism of siderophore interception and clearance by Scn; Serf is observed to release iron in acidic endosomes and [Fe(III)(Ent)](1-) is known to undergo a change from catecholate to salicylate coordination in acidic conditions, which is predicted to be sterically incompatible with the Scn binding pocket (also referred to as the calyx). To investigate the interactions between the ferric Ent complex and Scn at different pH values, two recombinant forms of Serf with mutations in three residues lining the calyx were prepared: Scn-W79A/R81A and Scn-Y106F. Binding studies and crystal structures of the Scn-W79A/R81A:[Fe(III)(Ent)](3-) and Scn-Y106F:[Fe(III)(Ent)](3-) complexes confirm that such mutations do not affect the overall conformation of the protein but do weaken significantly its affinity for [Fe(III)(Ent)](3-). Fluorescence, UV-vis, and EXAFS spectroscopies were used to determine Scn/siderophore dissociation constants and to characterize the coordination mode of iron over a wide pH range, in the presence of both mutant proteins and synthetic salicylate analogues of Ent. While Serf binding hinders salicylate coordination transformation, strong acidification results in the release of iron and degraded siderophore. Iron release may therefore result from a combination of Ent degradation and coordination change.

TI Single-crystal nanowires grown via electron-beam-induced deposition SO NANOTECHNOLOGY LA English DT Article ID EVAPORATED TUNGSTEN FILMS; THIN-FILMS; NANOSTRUCTURES; VAPOR; MICROSTRUCTURE; DECOMPOSITION; TEMPERATURE; RESISTIVITY; FABRICATION; PHASE AB Electron-beam-induced deposition (EBID) is a useful technique for direct-writing of three-dimensional dielectric, semiconductor, and metallic materials with nanoscale precision and resolution. The EBID process, however, has been limited in many cases because precursor byproducts (typically from organic precursors like W(CO)(6)) are incorporated into the deposited material resulting in contaminated and amorphous structures. In this work, we have investigated the structure and composition of EBID tungsten nanostructures as-deposited from a tungsten hexafluoride (WF(6)) precursor. High resolution transmission electron microscopy, electron diffraction and electron spectroscopy were employed to determine the effects that the electron beam scanning conditions have on the deposit characteristics. The results show that slow, one-dimensional lateral scanning produces textured beta-tungsten nanowire cores surrounded by an oxide secondary layer, while stationary vertical growth leads to single-crystal [100]-oriented W(3)O nanowires. Furthermore we correlate how the growth kinetics affect the resultant nanowire structure and composition. C1 [Klein, K. L.; Randolph, S. J.; Simpson, M. L.; Rack, P.

An oriented film of liquid crystal perylene diimide molecules reversibly switches between a red phase with narrow conduction and valence bands and a large bandwidth black phase as the pi-stacked chromophores shift just 1.6 angstrom relative to their neighbors. This shift causes a substantial change in the intermolecular electronic overlap between molecules. The polarization of maximum absorbance rotates similar to 90 degrees, from an apparently molecule centered transition to an intermolecular charge transfer (CT) transition polarized along the pi-pi stacking axis. The experimental results are further explored via density functional theory calculations on a dimer model that demonstrate the variations in energy and oscillator strength of the molecular (Frenkel) and CT transitions as the longitudinal molecular offset is varied. These results demonstrate the exquisite sensitivity of the electrical properties of organic semiconductors to slight variations in molecular stacking.

Gas chromatography techniques were used to measure the yield of hydrogen as a function of time under isothermal conditions between 75 and 90 degrees C to set the baseline. Solid-state B-11-NMR spectroscopy of the products produced after 1 mol equiv of hydrogen had been desorbed from AB (i.e., polyaminoborane) showed a complex mixture of sp(3) boron species. Raman microscopy was used to follow the transformation of crystalline AB to amorphous AB upon heating and the subsequent formation of the diammoniate of diborane (DADB). A gas buret was used to monitor the time-dependent release of hydrogen from AB in the presence of chemical additives. The combination of these approaches provides insight into the mechanism of hydrogen release from solid AB. The release of molecular hydrogen is described by a process involving sequential induction (disruption of dihydrogen bonds), nucleation (formation of DADB), and growth (hydrogen release through dehydrocoupling). Addition of DADB or ammonium chloride to neat AB significantly reduces the induction time for hydrogen release. These results provide approaches to improve the hydrogen storage properties of AB.

Understanding the structure and dynamics of excitons is important, for example, for developing technologies for light-emitting diodes or solar energy conversion. However, there has never been an experimental means to study the time-dependent structure of excitons directly. Here, we use causality-inverted inelastic x-ray scattering (IXS) to image the charge-transfer exciton in the prototype insulator LiF, with resolutions Delta t = 20.67 as (2.067 x 10(-17) S) in time and Delta x = 0.533 angstrom (5.33 x 10(-11) m) in space. Our results show that the exciton has a modulated internal structure and is coherently delocalized over two unit cells of the LiF crystal (approximate to 8 angstrom). This structure changes only modestly during the course of its life, which establishes it unambiguously as a Frenkel exciton and thus amenable to a simplified theoretical description. Our results resolve an old controversy about excitons in the alkali halides and demonstrate the utility of IXS for imaging attosecond electron dynamics in condensed matter.

P-V isotherms derived from the high-pressure x-ray spectra displayed a slight density hysteresis around 4.0 GPa and a sharp discontinuity at similar to 20.0 GPa. The latter transition is ascribed to a monoclinic-to-orthorhombic first-order phase transition in TNT. The conversion of the isothermal P-V data to the shock velocity-particle velocity plane revealed a deviation from linearity at low up, a cusp associated with the phase transition at high up, and general agreement with the wealth of unreacted Hugoniot data on TNT.

Strong diffuse scattering is observed at low temperatures. An external field applied along the (001) direction affects the diffuse scattering in the (HK0) plane significantly, suggesting a redistribution occurs between polar nanoregions of different polarizations perpendicular to the field. By contrast, the (001) field has no effect on the diffuse scattering in the (H0L) and (0KL) zones. (C) 2008 American Institute of Physics.

TI Usability levels for sparse linear algebra components SO CONCURRENCY AND COMPUTATION-PRACTICE & EXPERIENCE LA English DT Article DE component architecture and interfaces; sparse matrix computations; usability ID SYSTEMS; SOLVER AB Sparse matrix computations are ubiquitous in high-performance computing applications and often are their most computationally intensive part. In particular, efficient solution of large-scale linear systems may drastically improve the overall application performance. Thus, the choice and implementation of the linear system solver are of paramount importance. It is difficult, however, to navigate through a multitude of available solver packages and to tune their performance to the problem at hand, mainly because of the plethora of interfaces, each requiring application adaptations to match the specifics of solver packages. For example, different ways of setting parameters and a variety of sparse matrix formats hinder smooth interactions of sparse matrix computations with user applications. In this paper, interfaces designed for components that encapsulate sparse matrix computations are discussed in the light of their matching with application usability requirements. Consequently, we distinguish three levels of interfaces, high, medium, and low, corresponding to the degree of user involvement in the linear system solution process and in sparse matrix manipulations. We demonstrate when each interface design choice is applicable and how it may be used to further users' scientific goals. Component computational overheads caused by various design choices are also examined, ranging from low level, for matrix manipulation components, to high level, in which a single component contains the entire linear system solver.

Two approaches - element substitution and additive interaction - were attempted for reducing dehydriding temperatures and improving dehydriding-rehydriding reversibility. The oxide-modified borohydride, LiBH(4) 75% + TiO(2) 25%, desorbed 9 wt% hydrogen from 100 degrees C to 600 degrees C and absorbed 8 wt% hydrogen at 600 degrees C and 70 bar. The chloride-modified borohydride, LiBH(4) + 0.2MgCl(2) + 0.1 TiCl(3), desorbed 5 wt% hydrogen from 60 degrees C to 450 degrees C and absorbed 4.5 wt% hydrogen at 600 degrees C and 70 bar. XRD analysis evidences that LiBH(4) reacts with the additives. The residual gas analyzer (RGA) spectra show no diborane evolved from the above materials during dehydrogenation. The reduction of desorption temperature can be attributed to additives interaction with lithium borohydrides rather than element substitution. The reversibility of oxide-modified LiBH(4) deteriorates during repeatedly dehydriding-rehydriding due to increasing formation of Li(3)BO(3) and sequent deficiency of boron and lithium.

Recent investigations have studied the time and length scales characteristic of the onset of convection based on the framework of linear stability theory. It is well known that the non-autonomous nature of the resulting matrix does not allow a normal mode analysis and previous researchers have either used a quasi-static approximation or solved the initial-value problem with arbitrary initial conditions. In this manuscript, we describe and use the recently developed non-modal stability theory to compute maximum amplifications possible, optimized over all possible initial perturbations. Non-modal stability theory also provides us with the structure of the most-amplified (or optimal) perturbations. We also present the details of three-dimensional spectral calculations of the governing equations. The results of the amplifications predicted by non-modal theory compare well to those obtained from the spectral calculations.

Rapid solidification is a non-equilibrium process, with different degrees of departure from full equilibrium constituting a microstructural hierarchy that correlates with increasing solidification rate. In accordance with this the resultant HPGA powders show a variety of microstructures according to their particle diameters, corresponding to degree of undercooling, with an amorphous structure appearing at high cooling rates. Five distinct phases and microstructures have been identified at different undercoolings; Al solid solution, tetragonal Al11Sm3, two different orthorhombic phases, and an amorphous phase which exists in company with a high number density of Al nanocrystals. The product phases of the rapid solidification were identified and analyzed using high energy transmission X-ray diffraction (HEXRD), high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), Energy Dispersive Xray Spectroscopy (EDS) and thermal analysis (DSC). The results of the study will be helpful in identifying metastable phase hierarchy and glass formation during vitrification of marginal glass formers. Published by Elsevier B.V. C1 [Kalay, Y.

Phase separation resulted in the formation of isolated particles of the chromium-enriched a' phase. The aluminum and titanium were found to preferential partition to the iron-rich a phase. The partitioning of aluminum is consistent with theoretical calculations. The change in the scale of the chromium-enriched a' phase was found to fit a power law with a time exponent of 0.32 in accordance with that predicted by the classical Lifshitz, Slyozov and Wagner (LSW) theory. The solute concentrations of the coexisting a and a' phases were estimated from concentration frequency distributions with the Langer-Bar-on-Miller (LBM) method and proximity histograms. The hardness was linearly related to the chromium content of the ot' phase. (c) 2008 Elsevier BX All rights reserved. C1 [Capdevila, C.; Chao, J.; Gonzalez-Carrasco, J.

The light curves in four different energy bands display different features. At higher energy bands several peaks are seen in the light curve, while at lower energy bands a single broader bump dominates. It is expected that these different features are the result of a mixture of several components, each of which has different energetics and variability. We analyzed the time-resolved spectra, which were resolved into several components. These components can be classified into two distinct classes. One is a component that has an exponential decay of E-p with a characteristic timescale shorter than similar to 30 s; its spectrum is well represented by a broken power-law function, which is frequently observed in many prompt GRB emissions, so it should have an internal-shock origin. Another is a component whose E-p is almost unchanged with a characteristic timescale longer than similar to 60 s, and shows a very soft emission and slower variability. The spectrum is characterized by either a broken power law or a black-body spectrum. By assuming that the soft component is a thermal emission, the radiation radius is initially 4.4 x 10(6) km, which is a typical radius of a blue supergiant, and its expansion velocity is 2.4 x 10(5) km s(-1) in the source frame.

TI Graph transformation approaches for diverse routing in shared risk resource group (SRRG) failures SO COMPUTER NETWORKS LA English DT Article DE optical networks; restoration; protection; algorithms; diverse routing ID PATHS AB Failure resilience is a desired feature of the Internet. Most traditional restoration architectures assume single failure assumption, which is not adequate in present day WDM optical networks. Multiple link failure models, in the form of shared risk link groups (SRLG's) and shared risk node groups (SRNG's) are becoming critical in survivable optical network design. We classify both of these form of failures under a common scenario of shared risk resource groups (SRRG) failures. We develop graph transformation techniques for tolerating multiple failures arising out of shared resource group (SRRG) failures. Diverse routing in such multi-failure scenario essentially necessitates finding out two paths between a Source and a destination that are SRRG disjoint. The generalized diverse FOUtirIg problem has been proved to be NP-Complete. The proposed transformation techniques however provides a polynomial time solution for certain restrictive failure sets. We study how restorability can be achieved for dependent or shared risk link failures and multiple node failures and prove the validity of our approach for different network scenarios. Our proposed technique is capable of improving the diverse route computation by around 20-30% as compared to approaches proposed in the literature. Published by Elsevier B.V.

These clamps contain many positively charged residues that could curtail the sliding due to attractive interactions with the negatively charged DNA. By single-molecule spectroscopy we have observed a fluorescently labeled sliding clamp (polymerase III beta subunit or beta clamp) loaded onto freely diffusing, single-stranded M13 circular DNA annealed with fluorescently labeled DNA oligomers of up to 90 bases. We find that the diffusion constant for the beta clamp diffusing along DNA is on the order of 10(-14) m(2)/s, at least 3 orders of magnitude less than that for diffusion through water alone. We also find evidence that the beta clamp remains at the 3' end in the presence of Escherichia coli single-stranded-binding protein. These results may imply that the clamp not only acts to hold the polymerase on the DNA but also prevents excessive drifting along the DNA.

TI On the diurnal cycle of deep convection, high-level cloud, and upper troposphere water vapor in the Multiscale Modeling Framework SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article ID GENERAL-CIRCULATION MODEL; CUMULUS CONVECTION; RESOLVING MODEL; RADAR OBSERVATIONS; TOGA COARE; PRECIPITATION; SATELLITE; PARAMETERIZATION; TRMM; SENSITIVITIES AB [1] The Multiscale Modeling Framework (MMF), also called "superparameterization'', embeds a cloud-resolving model (CRM) at each grid column of a general circulation model to replace traditional parameterizations of moist convection and large-scale condensation. This study evaluates the diurnal cycle of deep convection, high-level clouds, and upper troposphere water vapor by applying an infrared (IR) brightness temperature (T-b) and a precipitation radar (PR) simulator to the CRM column data. Simulator results are then compared with IR radiances from geostationary satellites and PR reflectivities from the Tropical Rainfall Measuring Mission (TRMM). While the actual surface precipitation rate in the MMF has a reasonable diurnal phase and amplitude when compared with TRMM observations, the IR simulator results indicate an inconsistency in the diurnal anomalies of high-level clouds between the model and the geostationary satellite data. Primarily because of its excessive high-level clouds, the MMF overestimates the simulated precipitation index (PI) and fails to reproduce the observed diurnal cycle phase relationships among PI, high-level clouds, and upper troposphere relative humidity. The PR simulator results show that over the tropical oceans, the occurrence fraction of reflectivity in excess of 20 dBZ is almost 1 order of magnitude larger than the TRMM data especially at altitudes above 6 km. Both results suggest that the MMF oceanic convection is overactive and possible reasons for this bias are discussed. However, the joint distribution of simulated IR Tb and PR reflectivity indicates that the most intense deep convection is found more often over tropical land than ocean, in agreement with previous observational studies.

TI Improved fine-scale transport model performance using AUV and HSI feedback in a tidally dominated system SO JOURNAL OF GEOPHYSICAL RESEARCH-OCEANS LA English DT Article ID AUTONOMOUS UNDERWATER VEHICLE; PHILLS HYPERSPECTRAL IMAGER; PLUME; CALIBRATION; DISPERSION; FLOW AB One of the challenges for model prediction and validation is providing them with data of appropriate spatial and temporal resolution. The maturation and increased application of autonomous underwater vehicles (AUVs) in aquatic environments allows systematic data collection on these model-relevant scales. The goal of this study was to apply a fine-scale circulation and transport model (Delft3D) to improve AUV mission planning and use data collected by the AUV to evaluate and improve model performance. A dye release was conducted in a tidally dominated embayment, and a planning phase model based on the best available data was used as a baseline for evaluation and for AUV mission planning (forecast). The planning phase model correctly predicted the general shape and direction of the dye plume and allowed for successful mission planning. Subsequently, bathymetry data collected by the AUV was incorporated into the model (hindcast), with temperature and salinity collected before the experiment. Comparisons with fluorometer measurements from the AUV indicate that the model effectively predicted the edges of the plume and centerline location. The location was also confirmed by remote sensing from an aircraft. Thermal stratification was found to be an important fate mechanism in the final model, and the results demonstrate the integration of observational data sets for small, short-duration surface-contaminant releases. This study highlights the strength of a phased, iterative approach with observation platforms and may serve as a guide toward improving the performance and evaluation of future coastal hydrodynamic and transport modeling efforts.

TI Seismic structure of the crust and the upper mantle beneath the Himalayas: Evidence for eclogitization of lower crustal rocks in the Indian Plate SO JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH LA English DT Article ID POSITIONING SYSTEM MEASUREMENTS; LOCAL EARTHQUAKE TOMOGRAPHY; V-P/V-S; TIBETAN PLATEAU; VELOCITY STRUCTURE; SOUTHERN TIBET; GRAVITY-ANOMALIES; NEPAL HIMALAYA; COLLISION ZONE; EASTERN NEPAL AB Variations in the seismic velocity structure of the Himalayan collision zone include significant differences between its north and south portions, with transitions in physical properties across the Greater Himalaya. We combined P- and S-wave traveltimes from a temporary broadband seismic network in eastern Nepal and southern Tibet with arrival times at the permanent station network of the Department of Mines and Geology of Nepal to determine the seismic velocity structure across the Himalaya, using local earthquake tomography and traveltimes of regional earthquakes. The P-to-S velocity ratio (Vp/Vs) structure marks the difference between the Indian Plate and the overlying materials, with the Vp/Vs ratios being high for the former and low for the latter. We also found a significant increase in the uppermost mantle seismic velocities from south to north, reaching P- wave velocities (Vp) over 8.4 km/s north of the Greater Himalaya. These high Vp values do not seem to be the result of biases due to anisotropy in the upper mantle beneath the Greater and Tethyan Himalayas. Instead, we suggest that rocks in the lower crust of the underthrusting Indian Plate undergo metamorphism to eclogite as they plunge to greater depth beneath the mountain range, explaining the high seismic velocities.

The zeros as well as the angular dependence of the amplitude of the second harmonic deviate remarkably from the standard Lifshitz-Kosevich (LK) prediction. In contrast, the angular dependence of the fundamental dHvA amplitude as well as the spin-splitting zeros of the Shubnikov-de Haas (SdH) signal follow the LK theory. We can explain this behavior of the dHvA signal by small chemical-potential (CP) oscillations and find a very good agreement between theory and experiment. A detailed wave-shape analysis of the dHvA oscillations corroborates the existence of an oscillating CP. We discuss the absence of the above spin-zero effect in the SdH signal and argue that in beta ''-(BEDT-TTF)(2)SF(5)CH(2)CF(2)SO(3) it can be explained by an incoherent variable range hopping interlayer transport which is insensitive to the small CP oscillations.

CA Phenix Collaboration TI Particle-species dependent modification of jet-induced correlations in Au plus Au collisions at root s(NN)=200 GeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID ENERGY-LOSS AB Measurements in Au + Au collisions at root s(NN) = 200 GeV of jet correlations for a trigger hadron at intermediate transverse momentum (p(T,trig)) with associated mesons or baryons at lower p(T,assoc) indicate strong modification of the away-side jet. The ratio of jet-associated baryons to mesons increases with centrality and p(T,assoc). For the most central collisions, the ratio is similar to that for inclusive measurements. This trend is incompatible with in-vacuum fragmentation but could be due to jetlike contributions from correlated soft partons, which recombine upon hadronization.

CA BaBar Collaboration TI Observation of Y(3940)-> J/psi omega in B -> J/psi omega K at BABAR SO PHYSICAL REVIEW LETTERS LA English DT Article ID BELLE AB We present a study of the decays B(0,+) -> J/psi omega K(0,+) using 383 x 10(6) B (B) over bar events obtained with the BABAR detector at PEP-II. We observe Y(3940) -> J/psi omega, with mass 3914.6(-3.4)(+3.8)(stat) +/- 2.0(syst) MeV/c(2), and width 34(-8)(+12)(stat) +/- 5(syst) MeV. The ratio of B(0) and B(+) decay to YK is 0.27(-0.23)(+0.28)(stat)(-0.01)(+0.04)(syst), and the relevant B(0) and B(+) branching fractions are reported.

CA BaBar Collaboration TI Measurements of B ->{pi,eta,eta '}l nu(l) branching fractions and determination of vertical bar V-ub vertical bar with semileptonically tagged B mesons SO PHYSICAL REVIEW LETTERS LA English DT Article ID LATTICE QCD; DECAYS AB We report measurements of branching fractions for the decays B -> Pl nu(l), where P are the pseudoscalar charmless mesons pi(-), pi(0), eta and eta('), based on 348 fb(-1) of data collected with the BABAR detector, using B-0 and B+ mesons found in the recoil of a second B meson decaying as B -> D-(*())l nu(l). Assuming isospin symmetry, we combine pionic branching fractions to obtain B(B-0 -> pi(-)l(+)nu(l)) = (1.54 +/- 0.17((stat)) +/- 0.09((syst))) x 10(-4); we find 3.2 sigma evidence of the decay B+ -> eta l(+)nu(l) and measure its branching fraction to be (0.64 +/- 0.20((stat))+/- 0.03((syst)))x10(-4), and determine B(B+ -> eta'l(+)nu(l)) < 0.47 x 10(-4) to 90% confidence level. Using partial branching fractions for the pionic decays in ranges of the momentum transfer and a variety of form factor calculation, we obtain values of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element vertical bar V-ub vertical bar in ranging from 3.6 x 10(-3) to 4.1 x 10(-3).

TI Unusual magneto-optical phenomenon reveals low energy spin dispersion in the spin-1 anisotropic Heisenberg antiferromagnetic chain system NiCl(2)-4SC(NH(2))(2) SO PHYSICAL REVIEW LETTERS LA English DT Article ID EXCITATIONS; STATES AB Electron paramagnetic resonance measurements of NiCl(2)-4SC(NH(2))(2) reveal the low-energy spin dispersion, including a magnetic-field interval in which the two-magnon continuum is within k(B)T of the ground state, allowing a continuum of excitations over a range of k states, rather than only the k=0 single-magnon excitations. This produces a novel Y shape in the frequency-field EPR spectrum measured at T >= 1.5 K. Since the interchain coupling J(perpendicular to)< k(B)T, this shape can be reproduced by a single S=1 antiferromagnetic Heisenberg chain with a strong easy-plane single-ion anisotropy. Importantly, the combination of experiment and modeling we report herein demonstrates a powerful approach to probing spin dispersion in a wide range of interacting magnetic systems without the stringent sample requirements and complications associated with inelastic scattering experiments.

TI Neutron beam effects on spin-exchange-polarized (3)He SO PHYSICAL REVIEW LETTERS LA English DT Article ID HIGH-DENSITY; TARGETS; FILTER; VAPOR; RB AB We have observed depolarization effects when high intensity cold neutron beams are incident on alkali-metal spin-exchange-polarized (3)He cells used as neutron spin filters. This was first observed as a reduction of the maximum attainable (3)He polarization and was attributed to a decrease of alkali-metal polarization, which led us to directly measure alkali-metal polarization and spin relaxation over a range of neutron fluxes at Los Alamos Neutron Science Center and Institute Laue-Langevin. The data reveal a new alkali-metal spin-relaxation mechanism that approximately scales as root phi(n), where phi(n) is the neutron capture-flux density incident on the cell. This is consistent with an effect proportional to the concentration of electron-ion pairs but is much larger than expected from earlier work. C1 [Sharma, M.; Chupp, T. E.; Tardiff, E.

A magnetic field (B) applied along the tube axis brightened the dark state, leading to the emergence of a new emission peak. The peak rapidly grew in intensity with increasing B at the expense of the originally dominated bright exciton peak and became dominant at B > 3T. This behavior, universally observed for more than 50 tubes of different chiralities, can be quantitatively modeled by incorporating the Aharonov-Bohm effect and intervalley Coulomb mixing. The directly measured dark-bright splitting values were 1-4 meV for tube diameters 1.0-1.3 nm. Scatter in the splitting value emphasizes the role of the local environment surrounding a nanotube in determining its excitonic fine structure.

TI Metal-insulator transition by isovalent anion substitution in Ga(1-x)Mn(x)As: Implications to ferromagnetism SO PHYSICAL REVIEW LETTERS LA English DT Article ID MAGNETIC-PROPERTIES; ION-IMPLANTATION; SEMICONDUCTORS; (GA,MN)AS; GAAS AB We have investigated the effect of partial isovalent anion substitution in Ga(1-x)Mn(x)As on electrical transport and ferromagnetism. Substitution of only 2.4% of As by P induces a metal-insulator transition at a constant Mn doping of x=0.046 while the replacement of 0.4% As with N results in the crossover from metal to insulator for x=0.037. This remarkable behavior is consistent with a scenario in which holes located within an impurity band are scattered by alloy disorder in the anion sublattice. The shorter mean free path of holes, which mediate ferromagnetism, reduces the Curie temperature T(C) from 113 to 60 K (100 to 65 K) upon the introduction of 3.1% P (1% N) into the As sublattice.

Using photoelectron imaging, we show the effect of ICR on photoelectron angular distributions for a series of dianions, (-)O(2)C(CH(2))(n)CO(2)(-) (D(n)(2-)). The observed photoemission band of D(n)(2-) was due to a perpendicular transition from the charged end group. However, photoemission intensities were observed to peak along the laser polarization for smaller n due to the strong ICR that forces electrons to be emitted along the molecular axis.

TI Direct mapping of phonon dispersion relations in copper by momentum-resolved x-ray calorimetry SO PHYSICAL REVIEW LETTERS LA English DT Article ID TRANSMISSION SCATTERING; DIFFUSE-SCATTERING; SILICON; EXAMPLE AB We have developed a new method of mapping phonon dispersion relations based on momentum-resolved x-ray calorimetry. X-ray scattering intensities are measured at selected points in reciprocal space with suitably chosen polarization configurations; the thermal part of the scattering intensity is extracted by scanning the temperature of the sample. The intensity variations, governed by the phonon populations, are analyzed to yield the energies of the phonons. This method is applied to copper. With high-order effects under control, the results are in excellent agreement with the known phonon dispersion relations.

TI Metal to insulator transition in epitaxial graphene induced by molecular doping SO PHYSICAL REVIEW LETTERS LA English DT Article ID BILAYER GRAPHENE; ADSORPTION; GRAPHITE; SUBSTRATE; FILMS; NO2; N2O AB The capability to control the type and amount of charge carriers in a material and, in the extreme case, the transition from metal to insulator, is one of the key challenges of modern electronics. By employing angle-resolved photoemission spectroscopy we find that a reversible metal to insulator transition and a fine-tuning of the charge carriers from electrons to holes can be achieved in epitaxial bilayer and single layer graphene by molecular doping. The effects of electron screening and disorder are also discussed. These results demonstrate that epitaxial graphene is suitable for electronics applications, as well as provide new opportunities for studying the hole doping regime of the Dirac cone in graphene.

Until recently, metatranscriptomics has been limited to microarray technology and random cloning methodologies. The application of high-throughput sequencing technology is now enabling access to both known and previously unknown transcripts in natural communities. Methodology/Principal Findings: We present a study of a complex marine metatranscriptome obtained from random whole-community mRNA using the GS-FLX Pyrosequencing technology. Eight samples, four DNA and four mRNA, were processed from two time points in a controlled coastal ocean mesocosm study (Bergen, Norway) involving an induced phytoplankton bloom producing a total of 323,161,989 base pairs. Our study confirms the finding of the first published metatranscriptomic studies of marine and soil environments that metatranscriptomics targets highly expressed sequences which are frequently novel. Our alternative methodology increases the range of experimental options available for conducting such studies and is characterized by an exceptional enrichment of mRNA (99.92%) versus ribosomal RNA. Analysis of corresponding metagenomes confirms much higher levels of assembly in the metatranscriptomic samples and a far higher yield of large gene families with >100 members, similar to 91% of which were novel. Conclusions/Significance: This study provides further evidence that metatranscriptomic studies of natural microbial communities are not only feasible, but when paired with metagenomic data sets, offer an unprecedented opportunity to explore both structure and function of microbial communities-if we can overcome the challenges of elucidating the functions of so many never-seen-before gene families.

TI Transcriptome analysis reveals response regulator SO2426-mediated gene expression in Shewanella oneidensis MR-I under chromate challenge SO BMC GENOMICS LA English DT Article ID 2-COMPONENT SIGNAL-TRANSDUCTION; ESCHERICHIA-COLI; MUTATIONAL ANALYSIS; PUTREFACIENS MR-1; OXIDATIVE STRESS; SHOCK RESPONSE; IRON STORAGE; REDUCTION; SYSTEM; GROWTH AB Background: Shewanella oneidensis MR-I exhibits diverse metal ion-reducing capabilities and thus utility as a bioremediation agent. Knowledge of the molecular components and regulatory mechanisms dictating cellular responses to heavy metal stress, however, remains incomplete. In a previous work, the S. oneidensis so2426 gene, annotated as a DNA-binding response regulator, was demonstrated to be specifically responsive at both the transcript and protein levels to acute chromate [Cr(VI)] challenge. To delineate the cellular function of SO2426 and its contribution to metal stress response, we integrated genetic and physiological approaches with a genome-wide screen for target gene candidates comprising the SO2426 regulon. Results: Inactivation of so2426 by an in-frame deletion resulted in enhanced chromate senstivity and a reduced capacity to remove extracellular Cr(VI) relative to the parental strain. Time-resolved microarray analysis was used to compare transcriptomic profiles of wild-type and SO2426-deficient mutant S. oneidensis under conditions of chromate exposure. In total, 841 genes (18% of the array genome) were up- or downregulated at least twofold in the Delta so2426 mutant for at least one of six time-point conditions. Hierarchial cluster analysis of temporal transcriptional profiles identified a distinct cluster (n = 46) comprised of co-ordinately regulated genes exhibiting significant downregulated expression (p < 0.05) over time. Thirteen of these genes encoded proteins associated with transport and binding functions, particularly those involved in Fe transport and homeostasis (e.g., siderophote biosynthetic enzymes, TonB-dependent receptors, and the iron-storage protein ferritin). A conserved hypothetical operon (so1188-so1189-so1190), previously identified as a potential target of Furmediated repression, as well as putative bicyclomycin resistance gene (so2280) and cation efflux family protein gene (so2045) also were repressed in the so2426 deletion mutant. Furthermore, the temporal expression profiles of four regulatory genes including a cpxR homolog were perturbed in the chromate-challenged mutant. Conclusion: Our findings suggest a previously unrecognized functional role for the response regulator SO2426 in the activation of genes required for siderphore-mediated Fe acquistion. Fe storage, and other cation transport mechanisms. SO2426 regulatory function is involved at a fundamental molecular level in the linkage between Fe homeostasis and the cellular response to chromate-induced stress in S. oneidensis.

The approach is independent of the distribution of the observable and does not rely on any presumed kinetic model for the system's dynamical response. It provides a quantitative and objective framework for studies of complex systems exhibiting dynamics that are nonuniform in time. Applying this method to computer simulated data, it is shown that the wavelet correlation approach is capable of resolving the size fluctuations in a single nanostructure by single-molecule tracking spectroscopy.

While internal structure of large quantum dots is similar to bulk, their surface structure and passivating role of capping ligands (surfactants) are not fully understood to date. We apply ab initio wavefunction methods, density functional theory, and semiempirical approaches to study the passivation effects of substituted phosphine and amine ligands on the minimal cluster Cd2Se2, which is also used to benchmark different computational methods versus high level ab initio techniques. Full geometry optimization of Cd2Se2 at different theory levels and ligand coverage is used to understand the affinities of various ligands and the impact of ligands on cluster structure. Most possible bonding patterns between ligands and surface Cd/Se atoms are considered, including a ligand coordinated to Se atoms. The degree of passivation of Cd and Se atoms (one or two ligands attached to one atom) is also studied. The results suggest that B3LYP/LANL2DZ level of theory is appropriate for the system modeling, whereas frequently used semiempirical methods (such as AM1 and PM3) produce unphysical results. The use of hydrogen atom for modeling of the cluster passivating ligands is found to yield unphysical results as well. Hence, the surface termination of II-VI semiconductor NCs with hydrogen atoms often used in computational models should probably be avoided. Basis set superposition error, zero-point energy, and thermal corrections, as well as solvent effects simulated with polarized continuum model are found to produce minor variations on the ligand binding energies. The effects of Cd-Se complex structure on both the electronic band gap (highest occupied molecular orbital-lowest unoccupied molecular orbital energy difference) and ligand binding energies are systematically examined. The role played by positive charges on ligand binding is also explored. The calculated binding energies for various ligands L are found to decrease in the order PMe3>OPH3>NH2Me >= NH3 >= NMe3>PMe3>PH3 for neutral clusters and OPMe3>OPH3>PMe3 >= NMe3 >= NH2Me >= NH3>PH3 and OPMe3>OPH3>NH2Me >= NMe3 >= PMe3 >= NH3>PH3 for single and double ligations of positively charged Cd2Se22+ cluster, respectively.

TI Flux tube texture of the solar wind: Strands of the magnetic carpet at 1 AU? SO JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS LA English DT Review ID PRESSURE-BALANCED STRUCTURES; INTERPLANETARY SHOCK-WAVES; TANGENTIAL DISCONTINUITIES; ALFVEN WAVES; PLASMA SHEET; TECTONICS MODEL; CORONAL PLUMES; FREE-SURFACE; FIELD LINES; ZONAL FLOWS AB [1] It is argued here that the inner heliosphere is filled with a network of entangled magnetic flux tubes and that the flux tubes are fossil structures that originate at the solar surface. 65,860 flux tubes are collected from seven years of measurements with the ACE spacecraft at 1 AU by spotting the flux tube walls with large changes in the magnetic field direction and the vector flow velocity. The tube walls are associated with large changes in the ion entropy density and the alpha-to-proton ratio. The median size of the flux tubes at 1 AU is 4.4 x 10(5) km. The tubes are larger in slow wind than in fast wind. The tubes are on-average aligned with the Parker spiral, with a large spread in orientations. This large spread may be caused by slight misalignments of tubes in the corona. The flux tubes map to granule and supergranule sizes on the Sun. The amounts of magnetic flux in the tubes at 1 AU correspond to the amounts of magnetic flux in field concentrations in the magnetic carpet. It is argued that the flux tubes do not reconnect during the similar to 100-h advection to 1 AU owing to the expansion of the solar wind. The flux tube texture impacts the flow properties of the solar wind, turbulence in the solar wind, energetic-particle propagation in the inner heliosphere, and the driving of the Earth's magnetosphere. A method for using measurements of the flux tube walls for the remote sensing of magnetic field dynamics in the magnetic carpet is suggested.

Our results reveal two interesting and unanticipated outcomes: (i) methylation at the C2 position of [Im(ml)(+)] affords a significantly higher vaporization enthalpy; (ii) in all cases, the [beti(-)] anion served to lower the enthalpy of vaporization relative to [Tf(2)N(-)]. The widespread availability of the apparatus required for these measurements coupled with the ease of automation suggests the broad potential of this methodology for determining this critical parameter in a multitude of ILs.

This ionic liquid represents a group of task-specific silver complex-based ionic liquids synthesized recently. Molecular dynamics simulations at two temperatures are performed for five picoseconds. Events of association, dissociation, exchange, and recombination of ethylene with silver cation are found. A mechanism of ethylene transfer similar to the Grotthus type of proton transfer in water is identified, where a silver cation accepts one ethylene molecule and donates another to a neighboring silver cation. This mechanism may contribute to fast transport of olefins through ionic liquid membranes based on silver complexes for olefin/paraffin separation.

TI Molecular dynamics Simulations of the thermal conductivity of methane hydrate SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID LIQUID WATER; CLATHRATE HYDRATE; HEAT-CAPACITY; FORCE-FIELDS; ICE; ANHARMONICITY; SUMMATION; MODELS; SILICA AB Nonequilibrium molecular dynamics simulations with the nonpolarizable SPC/E (Berendsen et al., J. Phys. Chem. 1987, 91, 6269) and the polarizable COS/G2 (Yu and van Gunsteren, J. Chem. Phys. 2004, 121, 9549) force fields have been employed to calculate the thermal conductivity and other associated properties of methane hydrate over a temperature range from 30 to 260 K. The calculated results are compared to experimental data over this same range. The values of the thermal conductivity calculated with the COS/G2 model are closer to the experimental values than are those calculated with the nonpolarizable SPC/E model. The calculations match the temperature trend in the experimental data at temperatures below 50 K; however, they exhibit a slight decrease in thermal conductivity at higher temperatures in comparison to an opposite trend in the experimental data. The calculated thermal conductivity values are found to be relatively insensitive to the occupancy of the cages except at low (T <= 50 K) temperatures, which indicates that the differences between the two lattice structures may have a more dominant role than generally thought in explaining the low thermal conductivity of methane hydrate compared to ice Ih. The introduction of defects into the water lattice is found to cause a reduction in the thermal conductivity but to have a negligible impact on its temperature dependence.

TI Band edge recombination in CdSe, CdS and CdSxSe1-x alloy nanocrystals observed by ultrafast fluorescence upconversion: The effect of surface trap states SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID CHARGE-CARRIER DYNAMICS; QUANTUM DOTS; SEMICONDUCTOR CLUSTERS; RELAXATION DYNAMICS; EXCITON; PHOTOLUMINESCENCE; SPECTROSCOPY; SIZE; EFFICIENCY; EMISSION AB The effect of surface trap states on band edge recombination in CdSe, CdS and CdSxSe1-x alloy nanocrystals has been determined using fluorescence upconversion spectroscopy. These measurements reveal that there is both a size and composition dependence on the short-lived (tau(1)) and long-lived (tau(2)) components of fluorescence lifetime at the band edge. An increase in nanocrystal diameter, ranging from 23 to 60 angstrom, is accompanied by an increase in tau(1). This behavior is explained by the decrease in accessible trap sites through a reduction in surface-to-volume ratio. Similarly, tau(2) is found to increase with increasing nanocrystal size. However, with increasing sulfur concentration in the alloy nanocrystals, both a reduction in the magnitude of tau(1) and a reversal in the trend for tau(2) are observed. These changes in lifetimes associated with the addition of sulfur are explained by increased trapping on the nanocrystal surface. These results indicate that carrier dynamics may be controlled not only through size, but also through composition of the nanocrystals. Compositional variation has been shown not only to affect carrier dynamics, but also to affect the optical properties of nanocrystals. An increase in the Stokes shift is observed for CdSxSe1-x alloy nanocrystals as compared to CdSe and CdS nanocrystals. This indicates that the Stokes shift is highly influenced by the nonlinear effects of alloying.

We have a sample of similar to 37 000 spiral galaxies from the Sloan Digital Sky Survey, with their line of sight spin direction confidently classified by members of the public through the online project Galaxy Zoo. After establishing and correcting for a certain level of bias in our handedness results we find the winding sense of the galaxies to be consistent with statistical isotropy. In particular, we find no significant dipole signal, and thus no evidence for overall preferred handedness of the Universe. We compare this result to those of other authors and conclude that these may also be affected and explained by a bias effect.

TI The Trichoplax genome and the nature of placozoans SO NATURE LA English DT Article ID ADHAERENS SCHULZE,F.E. PLACOZOA; MAXIMUM-LIKELIHOOD; PROTEIN FAMILIES; ORIGIN; GENES; EVOLUTION; PHYLUM; DIVERSITY; CNIDARIAN; POSITION AB As arguably the simplest free- living animals, placozoans may represent a primitive metazoan form, yet their biology is poorly understood. Here we report the sequencing and analysis of the similar to 98 million base pair nuclear genome of the placozoan Trichoplax adhaerens. Whole- genome phylogenetic analysis suggests that placozoans belong to a 'eumetazoan' clade that includes cnidarians and bilaterians, with sponges as the earliest diverging animals. The compact genome shows conserved gene content, gene structure and synteny in relation to the human and other complex eumetazoan genomes. Despite the apparent cellular and organismal simplicity of Trichoplax, its genome encodes a rich array of transcription factor and signalling pathway genes that are typically associated with diverse cell types and developmental processes in eumetazoans, motivating further searches for cryptic cellular complexity and/ or as yet unobserved life history stages.

TI LaBr(3): Ce scintillators for in-beam gamma-ray spectroscopy with fast beams of rare isotopes SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE LaBr(3): Ce; gamma spectroscopy; radioactive ion beam ID COULOMB-EXCITATION; RELATIVISTIC ENERGIES; NUCLEAR SPECTROSCOPY; DEFORMATION; DETECTORS; RESOLUTION; ARRAY AB The scintillator material LaBr(3):Ce, which was discovered in 2001, has grown in popularity for a variety of applications in homeland security and nuclear medicine. In this paper we investigate its use for nuclear science spectroscopy applications in the context of in-beam gamma-ray spectroscopy with fast ion beams. in such experiments, the Doppler broadening of the gamma-ray line measured with a finite-size detector in the laboratory fundamentally limits the achievable energy resolution. For a typical experiment this effect is of the order of 3%. With the intrinsic energy resolution of LaBr(3):Ce better than 3% FWHM at 662 keV, and its favorable stopping power, it could be a nearly ideal scintillator for gamma-ray spectroscopy applications with fast beams. Results from in-beam gamma-ray spectroscopy measurements using two LaBr(3):Ce scintillators are presented and compared to results from segmented germanium detectors. Results from these measurements suggest that LaBr(3):Ce based scintillation arrays can provide a viable tool for many experiments. Additionally, we show that the excellent timing properties of LaBr(3):Ce can significantly reduce background events in the gamma-ray spectra. (C) 2008 Elsevier B.V. All rights reserved.

For a precise control of the vector sum of the signals coming from the SC cavities, the control system needs a high-performance, low-cost, reliable and modular multichannel receiver. At Fermilab we developed a 96-channel, 1.3 GHz analog/digital receiver for the ILC LINAC LLRF control system. in this paper we present a balanced design approach to the specifications of each receiver section, the design choices made to fulfill the goals and a description of the prototyped system. The design is tested by measuring standard performance parameters, such as noise figure, linearity and temperature sensitivity. Measurements show that the design meets the specifications and it is comparable to other similar systems developed at other laboratories, in terms of performance. (C) 2008 Elsevier B.V.

Copper-beryllium parallel-hole collimators suitable for imaging the similar to 35 keV photons from the decay of I-125 have been built and installed to achieve useful spatial resolution over a range of object-detector distances and to reduce imaging time on our dual-detector array. To address the resolution limitations in the parallel-hole SPECT and the sensitivity and limited field of view of single-pinhole SPECT, we have incorporated multipinhole circular and helical SPECT in addition to expanding the parallel-hole SPECT capabilities. The pinhole SPECT system is based on a 110 mm diameter circular detector equipped with a pixellated Nal(Tl) scintillator array (1 x 1 x 5 mm(3)/pixel). The helical trajectory is accomplished by two stepping motors controlling the rotation of the detector-support gantry and displacement of the animal bed along the axis of rotation of the gantry. Results obtained in SPECT studies of various phantoms show an enlarged field of view, very good resolution and improved sensitivity using multipinhole circular or helical SPECT. Collimators with one, three and five, 1-mm-diameter pinholes have been implemented and compared in these tests. Our objective is to develop a system on which one may readily select a suitable mode of either parallel-hole SPECT or pinhole circular or helical SPECT for a variety of small animal imaging applications.

TI The Early ANTP Gene Repertoire: Insights from the Placozoan Genome SO PLOS ONE LA English DT Article AB The evolution of ANTP genes in the Metazoa has been the subject of conflicting hypotheses derived from full or partial gene sequences and genomic organization in higher animals. Whole genome sequences have recently filled in some crucial gaps for the basal metazoan phyla Cnidaria and Porifera. Here we analyze the complete genome of Trichoplax adhaerens, representing the basal metazoan phylum Placozoa, for its set of ANTP class genes. The Trichoplax genome encodes representatives of Hox/ParaHox-like, NKL, and extended Hox genes. This repertoire possibly mirrors the condition of a hypothetical cnidarian-bilaterian ancestor. The evolution of the cnidarian and bilaterian ANTP gene repertoires can be deduced by a limited number of cis-duplications of NKL and "extended Hox'' genes and the presence of a single ancestral "ProtoHox'' gene.

TI Merger histories of galaxy halos and implications for disk survival SO ASTROPHYSICAL JOURNAL LA English DT Article DE cosmology : theory; dark matter; galaxies : formation; galaxies : halos; methods : n-body simulations ID COLD-DARK-MATTER; DIGITAL SKY SURVEY; TRIGGERED STAR-FORMATION; LARGE-SCALE STRUCTURE; ELLIPTIC GALAXIES; MILKY-WAY; STATISTICAL PROPERTIES; GALACTIC DISKS; MINOR MERGERS; ASSEMBLY HISTORIES AB We study the merger histories of galaxy dark matter halos using a high-resolution Lambda CDM N-body simulation. Our merger trees follow similar to 17,000 halos with masses M-0 = 10(11)-10(13) h(-1) M-circle dot at z = 0 and track accretion events involving objects as small as m similar or equal to 10(10) h(-1) M-circle dot. We find that mass assembly is remarkably self-similar in m/M-0 and dominated by mergers that are similar to 10% of the final halo mass. While very large mergers, m greater than or similar to 0.4M(0), are quite rare, sizeable accretion events, m similar to 0.1M(0), are common. Over the last similar to 10 Gyr, an overwhelming majority (similar to 95%) of Milky Way-sized halos with M-0 = 10(12) h(-1) M-circle dot have accreted at least one object with greater total mass than the Milky Way disk (m > 5 x 10(10) h(-1) M-circle dot), and approximately 70% have accreted an object with more than twice that mass (m > 10(11) h(-1) M-circle dot). Our results raise serious concerns about the survival of thin-disk-dominated galaxies within the current paradigm for galaxy formation in a Lambda CDM universe. In order to achieve a similar to 70% disk-dominated fraction in Milky Way-sized Lambda CDM halos, mergers involving m similar or equal to 2 x 10(11) h(-1) M-circle dot objects must not destroy disks. Considering that most thick disks and bulges contain old stellar populations, the situation is even more restrictive: these mergers must not heat disks or drive gas into their centers to create young bulges.

Surrounded by a compact dusty, gaseous disk, this little-studied late G ( or early K) type star emits about 75% of its detected energy flux at infrared wavelengths. Evidence for accretion of gas in conjunction with narrow bipolar jets and Herbig-Haro objects is apparently consistent with classification of BP Psc as a pre-main-sequence star, as postulated in most previous studies. If young, then BP Psc would be one of the nearest and oldest known classical T Tauri stars. However, such an evolutionary classification encounters various problems that are absent or much less severe if BP Psc is instead a luminosity class III post-main-sequence star. In this case, it would be the first known example of a first-ascent giant surrounded by a massive molecular disk with accompanying rapid gas accretion and prominent jets and HH objects. In this model, the genesis of the massive dusty gaseous disk could be a consequence of the envelopment of a low-mass companion star. Properties in the disk may be conducive to the current formation of planets, a gigayear or more after the formation of BP Psc itself. C1 [Zuckerman, B.; Melis, C.; Rhee, Joseph H.; Becklin, E.

We couple these spectral calculations to an updated version of the Marley et al. giant planet thermal evolution models that include formation by core accretion-gas capture. These relatively cool "young Jupiters'' can be 1-6 mag fainter than predicted by standard cooling tracks that include a traditional initial condition, which may provide a diagnostic of formation. If correct, this would make true Jupiter-like planets much more difficult to detect at young ages than previously thought. Since Jupiter and Saturn are of distinctly supersolar composition, we examine emitted spectra for model planets at both solar metallicity and a metallicity of 5 times solar. These metal-enhanced young Jupiters have lower pressure photospheres than field brown dwarfs of the same effective temperatures arising from both lower surface gravities and enhanced atmospheric opacity. We highlight several diagnostics for enhanced metallicity. A strongerCOabsorption band at 4.5 mu m for the warmest objects is predicted. At all temperatures, enhanced flux in K band is expected due to reduced collisional induced absorption by H-2. This leads to correspondingly redder near-infrared colors, which are redder than solar metallicity models with the same surface gravity by up to 0.7 in J-K and 1.5 in H-K. Molecular absorption band depths increase as well, most significantly for the coolest objects. We also qualitatively assess the changes to emitted spectra due to nonequilibrium chemistry.

We focus on coherent interactions between plasmon resonances and molecular excitations, which are experimentally challenging due to the very short (similar to 10-100 fs) coherence times of plasmons. Recent experimental results and theoretical analysis for observing and controlling coherences between molecular excitations and plasmonic polarizations are shown. Advances will explore new directions in ultrafast coherent control of molecular excited states and energy dissipation processes, as well as ultrafast addressing and switching in plasmonics-based circuit architectures.

The model relies on the screening of the energy of the local network based on the concept of 'strong'/`weak' nearest neighbor interactions according to their (trans/cis) orientation and the connectivity of the respective pairs to neighbors. We apply this model to the pentagonal dodecahedron (H2O)(20) cluster using a hierarchical description of the intermolecular interactions using classical interaction potentials and several levels of electronic structure methods. This study offers a practical and efficient approach for identifying stable networks in clathrate hydrate structures. Published by Elsevier B.V.

TI Flammability and thermal analysis characterization of imidazolium-based ionic liquids SO INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH LA English DT Article ID TRIALKYLIMIDAZOLIUM SALTS; RHODIUM COMPLEXES; HYDROGENATION; DEGRADATION; CATALYSIS AB Room-temperature ionic liquids have been identified as nonvolatile, nonflammable compounds with a wide range of applications. However, numerous thermal studies have identified volatile decomposition products and a source for fuel, raising questions regarding the fire hazard of ionic liquids. To address these questions, the flammability properties of imidazolium-based ionic liquids have been measured using cone calorimetry and microscale combustion calorimetry. The combustion data are compared to flashpoints estimated from thermal gravimetric analysis data. The resulting flammability properties of ionic liquids are comparable to aliphatic hydrocarbon plastics (polyethylene and polyamide) and lower than high boiling organic solvents (ethyl lactate and dimethyl sulfoxide). Several structure-property relationships are observed, including alkyl chain length and anion type. C1 [Fox, Douglas M.] American Univ, Dept Chem, Washington, DC 20016 USA.

Two different initial source zone architectures (one with and one without trapped NAPL) were considered and these architectures were used to evaluate seven different SVE scenarios. For all runs, slow diffusion from low permeability zones that gas flow bypassed was a dominant factor for diminished SVE effectiveness at later times. This effect was more significant at high water saturation due to the decrease of gas-phase relative permeability. Transverse dispersion contributed to fast NAPL mass removal from the low permeability layer in both source zone architectures, but longitudinal dispersion did not affect overall mass removal time. Both slow desorption from sediment grains and rate-limited mass transfer from trapped NAPL only marginally affected removal times. However, mass transfer from trapped NAPL did affect mass removal at later time, as well as the NAPL distribution. NAPL flow from low to high permeability zones contributed to faster mass removal from the low permeability layer, and this effect increased when water infiltration was eliminated. These simulations indicate that if trapped NAPL exists in heterogeneous porous media, mass transfer can be improved by delivering gas directly to zones with trapped NAPL and by lowering the water content, which increases the gas relative permeability and changes trapped NAPL to free NAPL.

In the new approach, the Euler potential a is no longer necessarily the magnetic flux, but can be specified much more freely, allowing equilibrium calculations in much more extended magnetospheric domains. With an empirical plasma pressure model as input and the T96 empirical magnetic field for boundary conditions, the new method is applied to compute a force balanced quiet time magnetospheric state extending to 30 RE in the magnetotail. While the force-balanced results for the magnetic field are not too different from T96 on the midnight axis, a very large discrepancy is found between field aligned currents (FACs) in the force balanced state and those computed from the empirical field and pressure using Vasyliunas equation; this shows that explicitly computed force balance is required for deriving FACs from plasma pressure and magnetic field by way of Vasyliunas equation.

The mechanisms underlying this impairment are not well understood, but brain dopamine systems have been implicated. Here, we test whether one night of sleep deprivation changes dopamine brain activity. We studied 15 healthy subjects using positron emission tomography and [C-11] raclopride (dopamineD(2)/D-3 receptor radioligand) and [C-11] cocaine (dopamine transporter radioligand). Subjects were tested twice: after one night of rested sleep and after one night of sleep deprivation. The specific binding of [C-11] raclopride in the striatum and thalamus were significantly reduced after sleep deprivation and the magnitude of this reduction correlated with increases in fatigue (tiredness and sleepiness) and with deterioration in cognitive performance (visual attention and working memory). In contrast, sleep deprivation did not affect the specific binding of [C-11] cocaine in the striatum. Because [C-11] raclopride competes with endogenous dopamine for binding to D-2/D-3 receptors, we interpret the decreases in binding to reflect dopamine increases with sleep deprivation. However, we cannot rule out the possibility that decreased [C-11] raclopride binding reflects decreases in receptor levels or affinity. Sleep deprivation did not affect dopamine transporters (target for most wake-promoting medications) and thus dopamine increases are likely to reflect increases in dopamine cell firing and/or release rather than decreases in dopamine reuptake. Because dopamine-enhancing drugs increase wakefulness, we postulate that dopamine increases after sleep deprivation is a mechanism by which the brain maintains arousal as the drive to sleep increases but one that is insufficient to counteract behavioral and cognitive impairment.

TI A combined neutron and x-ray diffraction study of short- and intermediate-range structural characteristics of Ge-As sulfide glasses SO JOURNAL OF PHYSICS-CONDENSED MATTER LA English DT Article ID ABSORPTION FINE-STRUCTURE; SOLID-STATE NMR; SELENIUM GLASSES; SPECTROSCOPY; SCATTERING; ORDER; GESE2; EXAFS AB A combination of neutron and x-ray diffraction has been employed to study the compositional dependence of the atomic structures of Ge(x)As(x)S(100-2x) glasses with S concentration varying between 33.3 and 70.0 at.%. The nearest-neighbor coordination numbers of Ge and As atoms are always found to be 4 and 3, respectively, irrespective of the glass composition. Ge and As atoms have primarily heteropolar bonding to S atoms in stoichiometric and S-excess glasses with x <= 18.2. Low and intermediate levels of deficiency of S (20 <= x <= 25) are accommodated via the formation of homopolar As-As bonds while Ge atoms remain primarily bonded to four S atoms, resulting in As-rich regions in the glass structure. Ge starts to participate in metal-metal bonding only in the highly S-deficient glasses with 27.5 <= x <= 33.3. The intermediate-range order and its topological influence on atomic packing in these three compositional regions, in the order of increasing deficiency in S, are controlled by (a) a mixed GeS(2) and As(2)S(3) network, (b) the coexistence of a GeS(2) network and As clusters, and (c) large Ge-As metal-rich regions. This evolution of the intermediate-range structure with composition is consistent with the corresponding variation of the position, intensity and width of the first sharp diffraction peak in the structure factor.

The reaction was determined to be first-order in Ta(V) surface coverage. The reaction rate exhibited saturation with respect to increasing concentrations of cyclohexene and H(2)O(2). An Eley-Rideal mechanism and rate equation may be used to describe the epoxidation kinetics, which are similar to those for Ti(IV)SiO(2)-catalyzed epoxidations. The observed kinetics may also be modeled by a double-displacement mechanism typically associated with saturation enzyme catalysts. In addition, (1)H NMR spectroscopy was employed to investigate H(2)O(2) decomposition by Bu(cap)TaSBA15 and the unmodified TaSBA15 catalysts. Little decomposition occurred over the surface-modified material, but the unmodified material catalyzed a 30% conversion of H(2)O(2) after 6 h. UV-visible absorbance and diffuse reflectance UV-visible (DRUV-vis) spectroscopy were used to investigate the structure of the Ta centers on the TaSBA15 catalysts. DRUV-vis spectroscopy was also used to identify a Ta(V)-based epoxidation intermediate, proposed to be a Ta(V) (eta(2)-O(2)) species, which forms upon reaction of the TaSBA15 and Bu(cap)TaSBA15 materials with H(2)O(2).

A total of 3584 individual ORFs (85%) have been successfully cloned into the entry plasmids. To validate the use of the clone set, three sets of ORFs were examined within three different destination vectors constructed in this study. Success rates for heterologous protein expression of S. oneidensis His-or His/GST-tagged proteins in E. coli were approximately 70%. The ArcA and NarP transcription factor proteins were tested in an in vitro binding assay to demonstrate that functional proteins can be successfully produced using the clone set. Further functional validation of the clone set was obtained from phage display experiments in which a phage encoding thioredoxin was successfully isolated from a pool of 80 different clones after three rounds of biopanning using immobilized anti-thioredoxin antibody as a target. This clone set complements existing genomic (e. g., whole-genome microarray) and other proteomic tools (e. g., mass spectrometry-based proteomic analysis), and facilitates a wide variety of integrated studies, including protein expression, purification, and functional analyses of proteins both in vivo and in vitro.

TI Prognostic Breast Cancer Signature Identified from 3D Culture Model Accurately Predicts Clinical Outcome across Independent Datasets SO PLOS ONE LA English DT Article AB Background: One of the major tenets in breast cancer research is that early detection is vital for patient survival by increasing treatment options. To that end, we have previously used a novel unsupervised approach to identify a set of genes whose expression predicts prognosis of breast cancer patients. The predictive genes were selected in a well-defined three dimensional (3D) cell culture model of non-malignant human mammary epithelial cell morphogenesis as downregulated during breast epithelial cell acinar formation and cell cycle arrest. Here we examine the ability of this gene signature (3D-signature) to predict prognosis in three independent breast cancer microarray datasets having 295, 286, and 118 samples, respectively. Methods and Findings: Our results show that the 3D-signature accurately predicts prognosis in three unrelated patient datasets. At 10 years, the probability of positive outcome was 52, 51, and 47 percent in the group with a poor-prognosis signature and 91, 75, and 71 percent in the group with a good-prognosis signature for the three datasets, respectively (Kaplan-Meier survival analysis, p<0.05). Hazard ratios for poor outcome were 5.5 (95% CI 3.0 to 12.2, p<0.0001), 2.4 (95% CI 1.6 to 3.6, p<0.0001) and 1.9 (95% CI 1.1 to 3.2, p = 0.016) and remained significant for the two larger datasets when corrected for estrogen receptor (ER) status. Hence the 3D-signature accurately predicts breast cancer outcome in both ER-positive and ER-negative tumors, though individual genes differed in their prognostic ability in the two subtypes. Genes that were prognostic in ER+ patients are AURKA, CEP55, RRM2, EPHA2, FGFBP1, and VRK1, while genes prognostic in ER-patients include ACTB, FOXM1 and SERPINE2 (Kaplan-Meier p<0.05). Multivariable Cox regression analysis in the largest dataset showed that the 3D-signature was a strong independent factor in predicting breast cancer outcome. Conclusions: The 3D-signature accurately predicts breast cancer outcome across multiple datasets and holds prognostic value for both ER-positive and ER-negative breast cancer. The signature was selected using a novel biological approach and hence holds promise to represent the key biological processes of breast cancer.

Crystallographic studies revealed nu 364Asp is part of hole "a" that interacts with knob "A" peptide mimic, GPRP. Biochemical studies have shown gamma 364Asp is critical to polymerization, as polymerization of variants gamma D364A, gamma D364H, and gamma D364V is exceptionally impaired. To understand the molecular basis for the aberrant function, we solved the crystal structure of fragment D from gamma D364A. Surprisingly, the structure (rfD-gamma D364A+GP) showed near normal "A:a" interactions with GPRP bound to hole "a" and no change in the overall structure of gamma D364A. Of note, inspection of the structure showed negative electrostatic potential inside hole "a" was diminished by this substitution. We examined GPRP binding to the gamma 364Asp variants in solution by plasmin protection assay. We found no protection of either gamma D364H or gamma D364V but partial protection of gamma D364A, indicating the peptide does not bind to either gamma D364H or gamma D364V and binds more weakly than normal to gamma D364A. We also examined protection by calcium and found all variants were indistinguishable from normal, suggesting the global structures of the variants are not markedly different from normal. Our data imply that gamma 364Asp per se is not required for knob "A" binding to hole "a"; rather, this residue's negative charge has a critical role in the electrostatic interactions that facilitate the important first step in fibrin polymerization.

Here, we report four apoenzyme and one product complex crystal structures of the Thermus thermophilus (HB27) U3S protein. The overlay of eight crystallographically unique U3S molecules reveals a huge range of conformational flexibility, including a "closed" product complex. The product, uro'gen III, binds between the two domains and is held in place by a network of hydrogen bonds between the product's side chain carboxylates and the protein's main chain amides. Interactions of the product A and B ring carboxylate side chains with both structural domains of U3S appear to dictate the relative orientation of the domains in the closed enzyme conformation and likely remain intact during catalysis. The product C and D rings are less constrained in the structure, consistent with the conformational changes required for the catalytic cyclization with inversion of D ring orientation. A conserved tyrosine residue is potentially positioned to facilitate loss of a hydroxyl from the substrate to initiate the catalytic reaction.

TI Time dependence in 3-D mantle convection models featuring evolving plates: Effect of lower mantle viscosity SO JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH LA English DT Article ID SPHERICAL-SHELL MODELS; TECTONIC PLATES; THERMAL-CONVECTION; SURFACE PLATES; DYNAMIC EARTH; HEATING MODE; POLAR WANDER; MOTIONS; GENERATION; FLOW AB dEvolving plate configurations and dynamically determined plate velocities are featured in Cartesian geometry mantle convection simulations. The numerical model enables the evolution of plate shape and size by migrating idealized plate triple junctions. The motion of the model triple junctions responds to the time-dependent velocities of the adjacent plates. Each calculation includes four high-viscosity plates in a 3 x 3 x 1 solution domain. We analyze the effect of plate evolution on the time dependence of plate velocity and heat flux in three different models characterized by lower mantle to upper mantle viscosity ratios of 30, 90, and 300. We examine the difference in behavior between calculations featuring fixed and mobile plate boundaries for each viscosity model. When plates are permitted to evolve in response to the convective vigor of the system, plate positions and shapes can change considerably while features in the high-viscosity lower mantle may change very little. In addition, plate velocities and surface heat flux can be highly time dependent. We find that when the contrast between lower mantle and upper mantle viscosity magnitude is a factor of 30, surface velocities may fluctuate by 75% of the mean value and heat flux by 60%. We also find that plate velocity evolution is characterized by periods of reorganization, punctuating more stable periods. When the lower mantle viscosity is increased to 90 times the upper mantle value, plate reorganization events also occur, but only when plate boundary motion is enabled. When the lower mantle to upper mantle viscosity contrast is increased to a factor of 300, we find that the mean surface velocity and heat flux become very steady in cases both with and without plate boundary evolution, despite the substantial migration of convergent plate boundaries in the former case.

The MOF was synthesized by two routes: first at 80 degrees C for two days with conventional heating, and second at 120 degrees C for 1 h using microwave heating. The two as-synthesized samples exhibit very similar powder X-ray diffraction patterns, but the evacuated samples show differences in nitrogen uptake. From the single-component CO2 and CH4 isotherms, mixture adsorption was predicted using the ideal adsorbed solution theory (IAST). The microwave sample shows a selectivity of similar to 30 for CO2 over CH4, which is among the highest selectivities reported for this separation. The applicability of IAST to this system was demonstrated by performing GCMC simulations for both single-component and mixture adsorption.

TI Experimentally determining the exchange parameters of quasi-two-dimensional Heisenberg magnets SO NEW JOURNAL OF PHYSICS LA English DT Article ID SQUARE LATTICE; SUPERCONDUCTIVITY; ANTIFERROMAGNETS; ENTANGLEMENT; OXIDES; MODEL AB Though long-range magnetic order cannot occur at temperatures T > 0 in a perfect two-dimensional ( 2D) Heisenberg magnet, real quasi-2D materials will invariably possess nonzero inter-plane coupling J(perpendicular to) driving the system to order at elevated temperatures. This process can be studied using quantum Monte Carlo calculations. However, it is difficult to test the results of these calculations experimentally since for highly anisotropic materials in which the in-plane coupling is comparable with attainable magnetic fields J(perpendicular to) is necessarily very small and inaccessible directly. In addition, because of the large anisotropy, the Neel temperatures are low and difficult to determine from thermodynamic measurements. Here, we present an elegant method of assessing the calculations via two independent experimental probes: pulsed-field magnetization in fields of up to 85 T, and muon-spin rotation. C1 [Goddard, P.

Synchrotron inelastic x-ray scattering measurements of oxygen K-edge excitations to 38 GPa reveal changes in electronic structure and bonding on compression of the molecular solid. The measurements show that O-2 molecules interact predominantly through the half-filled 1 pi(g)* orbital < 10 GPa. Enhanced intermolecular interactions develop because of increasing overlap of the 1 pi(g)* orbital in the low-pressure phases, leading to electron delocalization and ultimately intermolecular bonding between O-2 molecules at the transition to the E-phase. The E-phase, which consists of (O-2)(4) clusters, displays the bonding characteristics of a closed-shell system. Increasing interactions between (O-2)(4) clusters develop upon compression of the E-phase, and provide a potential mechanism for intercluster bonding in still higher-pressure phases.

TI Maximum height in a conifer is associated with conflicting requirements for xylem design SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE air-seeding pressure; bordered pit; embolism; hydraulic architecture; Pseudotsuga menziesii ID DOUGLAS-FIR TREES; AIR-SEEDING THRESHOLDS; BORDERED PIT FUNCTION; HYDRAULIC ARCHITECTURE; PSEUDOTSUGA-MENZIESII; ANGIOSPERM VESSELS; STOMATAL CONTROL; WATER TRANSPORT; FOREST TREES; LEAF AB Despite renewed interest in the nature of limitations on maximum tree height, the mechanisms governing ultimate and species-specific height limits are not yet understood, but they likely involve water transport dynamics. Tall trees experience increased risk of xylem embolism from air-seeding because tension in their water column increases with height because of path-length resistance and gravity. We used morphological measurements to estimate the hydraulic properties of the bordered pits between tracheids in Douglas-fir trees along a height gradient of 85 m. With increasing height, the xylem structural modifications that satisfied hydraulic requirements for avoidance of runaway embolism imposed increasing constraints on water transport efficiency. In the branches and trunks, the pit aperture diameter of tracheids decreases steadily with height, whereas torus diameter remains relatively constant. The resulting increase in the ratio of torus to pit aperture diameter allows the pits to withstand higher tensions before air-seeding but at the cost of reduced pit aperture conductance. Extrapolations of vertical trends for trunks and branches show that water transport across pits will approach zero at a heights of 109 m and 138 m, respectively, which is consistent with historic height records of 100-127 m for this species. Likewise, the twig water potential corresponding to the threshold for runaway embolism would be attained at a height of approximate to 107 m. Our results suggest that the maximum height of Douglas-fir trees may be limited in part by the conflicting requirements for water transport and water column safety.

Cyanobacteria, like plants, protect themselves from light-induced stress by dissipating excess absorbed energy as heat. Recently, it was discovered that a soluble orange carotenoid protein, the OCP, is essential for this photoprotective mechanism. Here we show that the OCP is also a member of the family of photoactive proteins; it is a unique example of a photoactive protein containing a carotenoid as the photoresponsive chromophore. Upon illumination with blue-green light, the OCP undergoes a reversible transformation from its dark stable orange form to a red "active" form. The red form is essential for the induction of the photoprotective mechanism. The illumination induces structural changes affecting both the carotenoid and the protein. Thus, the OCP is a photoactive protein that senses light intensity and triggers photoprotection.

Position sensitive d-spacings for the individual phases were obtained from spatially resolved and energy-resolved Laue patterns. For embedded Mo fibers, the measured elastic strain is consistent with the predicted thermal mismatch strain between the NiAl and Mo phases. However, when the NiAl matrix is etched back to expose Mo micropillars, the d-spacing increases to that of unconstrained Mo, indicating release of the compressive residual strain in the Mo fibers.

TI Steplike versus continuous domain propagation in Co/Pd multilayer films SO APPLIED PHYSICS LETTERS LA English DT Article ID X-RAY; HYSTERESIS; SCALE AB We investigate the microscopic reversal behavior in perpendicular-anisotropy magnetic thin films using an integrated mask-sample design that allows probing a nanoscale sample region with soft x-rays. Local hysteresis loops and spectroholography images are obtained from the transmitted signal exploiting x-ray magnetic circular dichroism. Our data provide direct evidence of microscopic spin-flip avalanches, such as responsible for Barkhausen noise. In comparison with macroscopic magnetometry measurements we find evidence for the sputter pressure dependent introduction of local defects that prevent a continuous domain wall motion but are not strong enough to introduce the appearance of microscopic return point memory.

This methodology allows the independent measurement of resonance frequency, Q factor, and oscillation amplitude of a tip-surface contact as a function of tip temperature, from which the thermal evolution of tip-surface spring constant and mechanical dissipation can be extracted. We demonstrate a heating protocol which keeps the contact area and contact force constant, thus allowing for reproducible measurements and quantitative extraction of material properties including temperature dependence of indentation-based elastic and loss moduli.

TI Three-dimensional atom probe investigation of boron distribution in CoFeB/MgO/CoFeB magnetic tunnel junctions SO APPLIED PHYSICS LETTERS LA English DT Article ID ROOM-TEMPERATURE; MAGNETORESISTANCE AB Significant lateral compositional variations have been revealed in a three-dimensional atom probe (3DAP) study of the MgO barriers of magnetic tunnel junctions. High resolution electron microscopy of the CoFeB/MgO/CoFeB/Ru/CoFe/PtMn multilayer indicates that the MgO barrier is smooth, uniform, and with good crystallinity. Nevertheless, the 3DAP data show lateral variations in the MgO composition over length scales on the order of tens of nanometers. Boron is not uniformly distributed within the CoFeB layers, but has tended to segregate to the interfaces. Annealing has no significant effect on the distribution of B, indicating that the segregation occurring during growth is relatively stable. (c) 2008 American Institute of Physics.

The conducting layer is similar to 3 nm deep and of width similar to 1 nm. In situ resistivity measurements were performed as the implantation proceeded, and the conductivity thus obtained as a function of buried gold concentration. The measured conductivity obeys the behavior well established for composites in the percolation regime. The critical concentration, below which the polymer remains an insulator, is attained at a dose similar to 1.0 x 10(16) atoms/cm(2) of implanted gold ions. (C) 2008 American Institute of Physics.

The results confirmed that the individual PbTiO3 nanocolumns in the CoFe2O4 matrix exhibit a detectable piezoelectric response regardless of substrate orientation. For the {100} and {110} orientations, a bias of +/- 10 V produced ferroelectric domain switching; however, no switching was observed for the {111} films. Small values of piezoelectric constants d(zz)((100))approximate to 11 pm/V, d(zz)((110))approximate to 5 pm/V, and d(zz)((111))approximate to 3pm/V are attributed to the weak intrinsic response of the nano-PbTiO3 under strong mechanical and depolarizing-field constraints in the composite films.

The silicalite-2 (ZSM-11) materials were synthesized using 3,5-dimethyl-N,N-diethylpiperdinium hydroxide as a. structure-directing agent to produce phase-pure ZSM-11 materials. No precipitation of manganese hydroxide was observed, and synthesis resulted in the incorporation of up to 2.5 mol % Mn into the silicalite-2 with direct substitution into the framework verified by the linear relationship between the unit cell volume and loading. The Mn is reduced to Mn-II during hydrothermal synthesis and incorporated into the silicalite-2 framework during calcination at 500 degrees C. Further calcination at 750 degrees C does not affect the crystallinity but oxidizes essentially all of the Mn-II to Mn-III in the framework. The large difference in oxidation temperatures between the II and III oxidation states provides a means of producing relatively pure manganese(II) and manganese(Ill) silicalite-2 materials for applications such as catalysis.

PANI-PPy nanofibers synthesized with an excess of either PANI or PPy show similar spectral (UV-vis and FT-IR) characteristics as the individual homopolymers, whereas nanofibers from an equimolar mixture of An and Py display unique spectral characteristics. PANI-PPy nanofibers undergo a spontaneous redox reaction with metal ions to produce metal nanoparticles with various morphologies and/or sizes. These findings may open new opportunities for synthesizing functional polymer nanofibers and metal nanoparticles with controllable sizes and/or morphologies.

Based on this treatment, we investigate the criteria needed to achieve an enhancement in various nonlinear effects, and to produce efficient sources of terahertz radiation, in particular.

We derive new general relationships based upon practical considerations. Our analysis shows that if the fiber's MFD could be increased arbitrarily, 36 kW of power could be obtained with diffraction-limited quality from a fiber laser or amplifier. This power limit is determined by thermal and non-linear limits that combine to prevent further power scaling, irrespective of increases in mode size. However, limits to the scaling of the MFD may restrict fiber lasers to lower output powers. (C) 2008 Optical Society of America.

The synthesis of this type of MSN materials is described along with the current methods for controlling the structural properties and chemical functionalization for biotechnological and biomedical applications. We summarized the advantages of using MSN for several drug delivery applications. The recent investigations of the biocompatibility of MSN in vitro are discussed. We also describe the exciting progress on using MSN to penetrate various cell membranes in animal and plant cells. The novel concept of gatekeeping is introduced and applied to the design of a variety of stimuli-responsive nanodevices. We envision that these MSN-based systems have a great potential for a variety of drug delivery applications, such as the site-specific delivery and intracellular controlled release of drugs, genes, and other therapeutic agents.

This micro fluorescence-activated cell sorter (mu FACS) uses an infrared laser to laterally deflect cells into a collection channel. Green-labeled macrophages were sorted from a 40/60 ratio mixture at a throughput of 22 cells/s over 30 min achieving a 93% sorting purity and a 60% recovery yield. To rule out potential photoinduced cell damage during optical deflection, we investigated the response of mouse macrophage to brief exposures (<4 ms) of focused 1064-nm laser light (9.6 W at the sample). We found no significant difference in viability, cell proliferation, activation state, and functionality between infrared-exposed and unexposed cells. Activation state was measured by the phosphorylation of ERK and nuclear translocation of NF-kappa B, while functionality was assessed in a similar manner, but after a lipopolysaccharide challenge. To demonstrate the selective nature of optical sorting, we isolated a subpopulation of macrophages highly infected with the fluorescently labeled pathogen Francisella tularensis subsp. novicida. A total of 10 738 infected cells were sorted at a throughput of 11 cells/s with 93% purity and 39% recovery.

TI Annotation of metagenome short reads using proxygenes SO BIOINFORMATICS LA English DT Article; Proceedings Paper CT Joint Meeting of the 7th European Conference on Computational Biology/5th Meeting of the Bioinformatics-Italian-Society CY SEP 22-26, 2008 CL Cagliari, ITALY SP Bioinformat Italian Soc ID GENOME ANNOTATION; PROTEIN FAMILIES; DATABASE AB Motivation: A typical metagenome dataset generated using a 454 pyrosequencing platform consists of short reads sampled from the collective genome of a microbial community. The amount of sequence in such datasets is usually insufficient for assembly, and traditional gene prediction cannot be applied to unassembled short reads. As a result, analysis of such datasets usually involves comparisons in terms of relative abundances of various protein families. The latter requires assignment of individual reads to protein families, which is hindered by the fact that short reads contain only a fragment, usually small, of a protein. Results: We have considered the assignment of pyrosequencing reads to protein families directly using RPS-BLAST against COG and Pfam databases and indirectly via proxygenes that are identified using BLASTx searches against protein sequence databases. Using simulated metagenome datasets as benchmarks, we show that the proxygene method is more accurate than the direct assignment. We introduce a clustering method which significantly reduces the size of a metagenome dataset while maintaining a faithful representation of its functional and taxonomic content.

The REACH (Realistic Extension Algorithm via Covariance Hessian) coarse-graining method, in which the force constants of a residue-scale elastic network model are calculated from the variance-covariance matrix obtained from atomistic molecular dynamics (MD) simulation, involves direct mapping between scales without the need for iterative optimization. Here, the transferability of the REACH force field is examined between protein molecules of different structural classes. As test cases, myoglobin (all a), plastocyanin (all beta), and dihydrofolate reductase (alpha/beta) are taken. The force constants derived are found to be closely similar in all three proteins. An MD version of REACH is presented, and low-temperature coarse-grained (CG) REACH MD simulations of the three proteins are compared with atomistic MD results. The mean-square fluctuations of the atomistic MD are well reproduced by the CGMD. Model functions for the CG interactions, derived by averaging over the three proteins, are also shown to produce fluctuations in good agreement with the atomistic MD. The results indicate that, similarly to the use of atomistic force fields, it is now possible to use a single, generic REACH force field for all protein studies, without having first to derive parameters from atomistic MD simulation for each individual system studied. The REACH method is thus likely to be a reliable way of determining spatiotemporal motion of a variety of proteins without the need for expensive computation of long atomistic MD simulations.

Such amorphous uranyl-silicates may be related to the crystalline phases predicted to be thermodynamically stable and influence the mobility of U in the environment. To investigate amorphous uranyl-silicates and their relation to crystalline phases we precipitated solids from solutions containing 0.05 M UO2(ClO4)(2) and 0.1 M Na2SiO3 adjusted to pH values from 2.2 to 9 and allowed the precipitates to age in their mother liquors for approximately 6 weeks at 22 degrees C. We compared the chemical composition, X-ray diffraction patterns, and Fourier transform infrared spectra of the precipitates to those of the crystalline phases predicted by thermodynamic modeling. The precipitates were amorphous with U:Si ratios of 0.8 +/- 0.1. Their FTIR spectra revealed changes in the UO22+ and SiO44- vibrations as a function of pH that are consistent with a shift in mid-range structural linkages from those similar to soddyite to those more like Na-boltwoodite. Structural H2O, OH, and SiO3OH3- vibrations do not change as a function of pH and are consistent with a mixture of soddyite-like and Na-boltwoodite-like features. Six weeks of aging at ambient temperature is enough time for the precipitate structures to rearrange and adopt mid-range structural linkages characteristic Of Crystalline phases predicted by thermodynamic modeling.

TI Effects of physical erosion on chemical denudation rates: A numerical modeling study of soil-mantled hillslopes SO EARTH AND PLANETARY SCIENCE LETTERS LA English DT Article DE chemical weathering; physical erosion; denudation; cosmogenic nuclides ID GEOCHEMICAL MASS-BALANCE; WEATHERING RATES; COSMOGENIC NUCLIDES; GRANITOID ROCKS; TEMPERATURE; TRANSPORT; LANDSCAPES; PRESSURE; SEDIMENT; REGOLITH AB Many biogeochemical and Earth surface processes depend critically on chemical weathering. The immediate products of chemical weathering are present as solutes and secondary minerals in groundwater, soils, and streams, and form the nutritional foundation for terrestrial biogeochemistry. Chemical weathering also contributes to physical erosion by weakening bedrock and producing easily erodible regolith, and as the primary long-term sink for atmospheric CO(2) it modulates Earth's long-term climate via the greenhouse effect. Long-term chemical denudation rates on soil-mantled hillslopes can be estimated from cosmogenic radionuclide (CRN) concentrations in soil-borne quartz and the enrichment of a chemically inert tracer in soil relative to its parent bedrock, a technique that inherently assumes steady physical erosion over the timescale of CRN accumulation. We present a numerical model that Computes changes in soil mineralogy and CRN concentrations under time-varying physical erosion rates, and we use this model to assess the accuracy of the CRN-based technique for estimating chemical denudation rates in non-steady conditions. Our modeling results Suggest that CRN-based estimates of chemical denudation rates closely resemble actual chemical denudation rates averaged over the timescale of CRN accumulation, even during large-amplitude and long-period oscillations in physical erosion rates. For example, this model predicts that when physical erosion rates fluctuate sinusoidally by 50% of their mean over any period in time, CRN-based estimates of chemical denudation rates should differ from actual chemical denudation rates by less than 15%. Our model also implies that chemical denudation rates should approach zero both when physical erosion rates approach zero (because soluble minerals become depleted in the soil) and when physical erosion rates approach the maximum soil production rate (because soil thickness approaches zero). Modeled chemical denudation rates thus reach a maximum at intermediate physical erosion rates. If this relationship holds in nature, it implies that in rapidly eroding regions, further increases in physical erosion rates (e.g., due to increases in tectonic uplift rates) may not necessarily lead to faster chemical denudation on soil-mantled hillslopes.

TI Comparative assessments of benzene, toluene, and xylene natural attenuation by quantitative polymerase chain reaction analysis of a catabolic gene, signature metabolites, and compound-specific isotope analysis SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID SULFATE-REDUCING AQUIFER; IN-SITU DEGRADATION; SP STRAIN-T; BENZYLSUCCINATE SYNTHASE; ANAEROBIC TOLUENE; AROMATIC-HYDROCARBONS; CONTAMINATED AQUIFER; O-XYLENE; BIODEGRADATION; ETHANOL AB A controlled-release study conducted at Vandenberg. Air Force Base involved the injection of anaerobic groundwater amended with benzene, toluene, and o-xylene (BToX; 1-3 mg/L each) in two parallel lanes: lane A injectate contained no ethanol, whereas lane B injectate contained similar to 500 mg/L ethanol. As reported previously by Mackay and co-workers, ethanol led to slower BToX disappearance in lane B. Here, we report on assessments of BToX natural attenuation by three independent and specific monitoring approaches: signature metabolites diagnostic of anaerobic TX metabolism (benzysuccinates), compound-specific isotope analysis (CSIA), and quantitative polymerase chain reaction (qPCR) analysis of a catabolic gene involved in anaerobic TX degradation (bssA). In combination, the three monitoring methods provided strong evidence of in situ TX biodegradation in both lanes A and B; however, no single method provided strong evidence for TX biodegradation in both lanes. Benzylsuccinates were detected almost exclusively in lane B, where slower TX degradation and higher residual TX concentrations led to higher metabolite concentrations. In contrast, CSIA provided evidence of TX biodegradation almost exclusively in lane A, as greater degradation rates led to more pronounced isotopic enrichment. qPCR analyses of bssA were more complex. Evidence of increases in bssA copy number (up to 200-fold) after the release started was stronger in lane A, but higher absolute bssA copy number (and bacterial abundance, based on 16S rRNA genes) was observed in lane B, where bacteria genetically capable of anaerobic TX degradation may have been growing primarily on ethanol or its metabolites rather than TX.

Thaulow, Niels TI Rate of CO(2) attack on hydrated Class H well cement under geologic sequestration conditions SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID DEEP SALINE AQUIFERS; ELOVICH EQUATION; KINETICS AB Experiments were conducted to study the degradation of hardened cement paste due to exposure to CO(2) and brine under geologic sequestration conditions (T = 50 degrees C and 30.3 MPa). The goal was to determine the rate of reaction of hydrated cement exposed to supercritical CO(2) and to CO(2)-saturated brine to assess the potential impact of degradation in existing wells on CO(2) storage integrity. Two different forms of chemical alteration were observed. The supercritical CO(2) alteration of cement was similar in process to cement in contact with atmospheric CO(2) (ordinary carbonation), while alteration of cement exposed to CO(2)-saturated brine was typical of acid attack on cement. Extrapolation of the hydrated cement alteration rate measured for I year indicates a penetration depth range of 1.00 +/- 0.07 mm for the CO(2)-saturated brine and 1.68 +/- 0.24 mm for the supercritical CO(2) after 30 years. These penetration depths are consistent with observations of field samples from an enhanced oil recovery site after 30 years of exposure to CO(2)-saturated brine under similar temperature and pressure conditions. These results suggest that significant degradation due to matrix diffusion of CO(2) in intact Class H neat hydrated cement is unlikely on time scales of decades.

These variations may be correlated with the variations in the activity of indigenous As(III)- and Fe(II)-oxidizing bacteria living in the As-rich Carnoules water. The activity of these bacteria indeed plays an important role in the nature and composition of the solid phases that sequester arsenic at this site. In order to better understand the interactions of microbes with Fe and As in the Carnoules AMD, we combined Transmission Electron Microscopy (TEM) and Scanning Transmission X-ray Microscopy (STXM) to collect near-edge X-ray absorption fine structure (NEXAFS) spectra at high spatial and energy resolution and to perform high spatial resolution imaging at the 30-50 nm scale. Spectromicroscopy was performed at the C K-edge, Fe L-2,L-3-edge, and As L-2,L-3-edge, which allowed us to locate living and/or mineralized bacterial cells and to characterize Fe and As oxidation states in the vicinity of those cells. TEM was used to image the same areas, providing higher resolution images and complementary crystallographic and compositional information through electron diffraction and EDXS analysis. This approach provides unique information on heterogeneous geochemical processes that occur in a complex microbial community in an AMD environment at the micrometer and submicrometer-scale. Bacterial cells in the Carnoules AMD were frequently associated with mineral precipitates, and a variety of biomineralization patterns were observed. While many mineral precipitates were not associated with bacterial cells, they were associated with pervasive organic carbon. Finally, abundant biomineralized organic vesicles were observed in the Carnoules AMD. Such vesicles may have been overlooked in highly mineralized extreme environments in the past and may represent an important component in a common biomineralization process in such environments.

TI The Fe-C system at 5 GPa and implications for Earth's core SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID IRON-METEORITES; OS-186-OS-187 SYSTEMATICS; MANTLE INTERACTION; CARBON; FRACTIONATION; CRYSTALLIZATION; COSMOCHEMISTRY; TEMPERATURE; KOMATIITES; PRESSURE AB Earth's core may contain C, and it has been suggested that C in the core Could stabilize the formation of a solid inner core composed of Fe3C. We experimentally examined the Fe-C system at a pressure of 5 GPa and determined the Fe-C phase diagram at this pressure. In addition, we measured solid metal/liquid metal partition coefficients for 17 trace elements and examined the partitioning behavior between Fe3C and liquid metal for 14 trace elements. Solid metal/liquid metal partition coefficients are similar to those found in one atmosphere studies, indicating that the effect of pressure to 5 GPa is negligible. All measured Fe3C/liquid metal partition coefficients investigated are less than one, such that all trace elements prefer the C-rich liquid to Fe3C. Fe3C/liquid metal partition coefficients tend to decrease with decreasing atomic radii within a given period. Of particular interest, our 5 GPa Fe-C phase diagram does not show any evidence that the Fe-Fe3C eutectic composition shifts to lower C contents with increasing pressure, which is central to the previous reasoning that the inner core may be composed of Fe3C.

TI Exothermic reactions in Co/Al nanolaminates SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID COMBUSTION SYNTHESIS; EXPLOSIVE CRYSTALLIZATION; MULTILAYER FOILS; SURFACE UNDULATIONS; THIN-FILMS; PROPAGATION AB Vapor-deposited Co/Al nanolaminates having a net equiatomic stoichiometry exhibited rapid, high-temperature synthesis. When ignited locally, 7.5-mu m-thick Co/Al foils were characterized by self-sustained propagating reactions with flame front speeds between similar to 0.5 and 9 m/s. Speed was largely affected by bilayer thickness and premixed volume fraction, consistent with previous studies of other exothermic multilayers. Cobalt aluminide foils reacted by self-propagating synthesis developed a variety of rough surface morphologies characterized by a large amplitude (peak-to-valley similar to 1.0 mu m), multiperiod, wavelike structure. High-temperature reaction was also stimulated by rapid global heating. Tests revealed low ignition temperatures (T-ig)similar to 240-460 degrees C compared with previous Co-Al powder reactant experiments. Ignition temperature was influenced by bilayer thickness. All foils ignited by global heating and those reacted in a self-propagating mode developed a single-phase B2 (CsCl-type) crystal structure. Thick Co/Al nanolaminates were used successfully to join a few different materials including metalized Al2O3 (by soldering) and polyetheretherketone (by direct attachment).

TI Enhanced flux pinning and critical currents in YBa(2)Cu(3)O(7-delta) films by nanoparticle surface decoration: Extension to coated conductor templates SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID SUPERCONDUCTING THIN-FILMS; MAGNETIC-FIELD DEPENDENCE; CRITICAL-CURRENT DENSITY; II SUPERCONDUCTORS; CENTERS; DISPERSIONS; TEMPERATURE; NANODOTS; DEFECTS; LAYER AB Interfacial engineering via nanoparticle substrate surface decoration has been extended to coated conductor templates. Preformed BaTiO(3) and BaZrO(3) nanoparticles were applied to substrate surfaces, prior to YBa(2)Cu(3)O(7-delta) (YBCO) deposition, by using a scalable and inexpensive technique of solution-based suspension. Compared to untreated reference samples, nanodecoration yields improved in-field critical current density (J(c)) as well as strong correlated pinning along the c-axis direction of the YBCO film. Accordingly, a much reduced falloff of J(c) with magnetic field strength was observed in all of the modified samples. In addition, scaling behavior of the normalized volume pinning force density (F(p)) with respect to temperature provided insight as to the differences in flux pinning mechanisms dependent on the decoration technique. Finally, with these results our earlier proof-of-concept demonstrations on nanoparticle modified single crystal substrates were replicated on technological substrates, pointing to the versatility of this simple technique for realization of enhanced high temperature superconductor performance.

TI Magnetic anisotropy of ferromagnetic Ga(1-x)Mn(x)As formed by Mn ion implantation and pulsed-laser melting SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID SEMICONDUCTORS; TEMPERATURE AB We measured the magnetic anisotropy of nearly fully relaxed ferromagnetic Ga(1-x)Mn(x)As formed by Mn ion implantation followed by pulsed-laser melting (II-PLM) using magnetometry and ferromagnetic resonance. In qualitative terms the material formed by II-PLM exhibits all magneticanisotropy features commonly found in Ga(1-x)Mn(x)As films fabricated by low-temperature molecular beam epitaxy (LT-MBE). Quantitatively, however, the magnetic anisotropy of II-PLM Ga(1-x)Mn(x)As is dominated by cubic anisotropy terms, which we attribute to the smaller strain in the II-PLM material due to the absence of Mn interstitials. One should note, however, that II-PLM Ga(1-x)Mn(x)As also exhibits a weak but finite uniaxial in-plane magnetic anisotropy similar to that observed in LT-MBE Ga(1-x)Mn(x)As, which can be ascribed to the small built-in compressive strain. The similarity between II-PLM and LT-MBE Ga(1-x)Mn(x)As clearly points to an intrinsic origin of this property, independent of the method of fabrication. At low temperatures the remnant in-plane magnetization of the II-PLM film exhibits single-domain characteristics, while perpendicular magnetization shows a multiple-domain behavior.

The equilibrium point defect concentrations are obtained via a self-consistent determination of the electron chemical potential. This allows one to derive charge carrier concentrations for a given temperature and chemical environment and eventually the electrical conductivity. The calculations are in excellent agreement with experimental data if an accidental acceptor dopant level of 10(17) cm(3) is assumed. It is shown that doubly charged oxygen vacancies are accountable for the high-temperature n-type conduction under oxygen-poor conditions. The high-temperature p-type conduction observed at large oxygen pressures is due to barium vacancies and titanium-oxygen divacancies under Ti- and Ba-rich conditions, respectively. Finally, the connection between the present approach and the mass-action law approach to point defect thermodynamics is discussed. (C) 2008 American Institute of Physics.

TI Indentation size effects in single crystal copper as revealed by synchrotron x-ray microdiffraction SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID STRAIN GRADIENT PLASTICITY; DEFORMATION MICROSTRUCTURE; STRUCTURAL MICROSCOPY; MECHANICAL-PROPERTIES; DISPLACEMENT FIELD; METALLIC MATERIALS; THIN-FILMS; HARDNESS; CU; NANOINDENTATION AB For a Cu single crystal, we find that indentation hardness increases with decreasing indentation depth, a phenomenon widely observed before and called the indentation size effect (ISE). To understand the underlying mechanism, we measure the lattice rotations in indentations of different sizes using white beam x-ray microdiffraction (mu XRD); the indentation-induced lattice rotations are directly measured by the streaking of x-ray Laue spots associated with the indentations. The magnitude of the lattice rotations is found to be independent of indentation size, which is consistent with the basic tenets of the ISE model. Using the mu XRD data together with an ISE model, we can estimate the effective radius of the indentation plastic zone, and the estimate is consistent with the value predicted by a finite element analysis. Using these results, an estimate of the average dislocation densities within the plastic zones has been made; the findings are consistent with the ISE arising from a dependence of the dislocation density on the depth of indentation.

The sample is an actual voltage-operated optical switch consisting of a series of triangular polarization-inverted domains formed in an originally poled single crystal. By applying an electric field only about 2% of the coercive field in the forward and reverse directions, we observed asymmetric lattice rotation of about 10(-6) rad, and normal strain variation in the order of 10(-5) with reference to the zero-field state. Our results confirm that in congruent LiTaO(3) crystals there is unexpectedly large strain field expanding several micrometers across the domain walls, in contrast with the widely accepted theoretical fact that in this material the polarization reversal establishes over only a few lattice constants. resulting in small and localized lattice distortions.

TI Model of defect reactions and the influence of clustering in pulse-neutron-irradiated Si SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID SILICON DEVICES; SEMICONDUCTORS; SIMULATION; MECHANISM; CASCADES AB Transient reactions among irradiation defects, dopants, impurities, and carriers in pulse-neutron-irradiated Si were modeled taking into account the clustering of the primal defects in recoil cascades. Continuum equations describing the diffusion, field drift, and reactions of relevant species were numerically solved for a submicrometer spherical volume, within which the starting radial distributions of defects could be varied in accord with the degree of clustering. The radial profiles corresponding to neutron irradiation were chosen through pair-correlation-function analysis of vacancy and interstitial distributions obtained from the binary-collision code MARLOWE, using a spectrum of primary recoil energies computed for a fast-burst fission reactor. Model predictions of transient behavior were compared with a variety of experimental results from irradiated bulk Si, solar cells, and bipolar-junction transistors. The influence of defect clustering during neutron bombardment was further distinguished through contrast with electron irradiation, where the primal point defects are more uniformly dispersed.

TI Carbon atom and cluster sputtering under low-energy noble gas plasma bombardment SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID ELECTRON-IMPACT IONIZATION; ANGULAR-DISTRIBUTION; ION-BOMBARDMENT; CROSS-SECTIONS; YIELDS; DISTRIBUTIONS; MOLYBDENUM; THRESHOLD; EROSION AB Exit-angle resolved carbon atom and cluster (C(2) and C(3)) sputtering yields are measured during different noble gas (Xe, Kr, Ar, Ne, and He) ion bombardments from a plasma, for low incident energies (75-225 eV). A quadrupole mass spectrometer (QMS) is used to detect the fraction of sputtered neutrals that is ionized in the plasma and to obtain the angular distribution by changing the angle between the target normal and the QMS aperture. A one-dimensional Monte Carlo code is used to simulate the interaction of the plasma and the sputtered particles in the region between the sample and the QMS. The effective elastic scattering cross sections of C, C(2), and C(3) with the different bombarding gas neutrals are obtained by varying the distance between the sample and the QMS and by performing a best fit of the simulation results to the experimental results. The total sputtering yield (C+C(2)+C(3)) for each bombarding gas is obtained from weight-loss measurements and the sputtering yield for C, C(2), and C(3) is then calculated from the integration of the measured angular distribution, taking into account the scattering and ionization of the sputtered particles between the sample and the QMS. We observe undercosine angular distributions of the sputtered atoms and clusters for all the studied bombarding gases and a clear decrease of the atom to cluster (C(2) and C(3)) sputtering ratio as the incident ion mass increases, changing from a carbon atom preferential erosion for the lower incident ion masses (He, Ne, and Ar) to a cluster preferential erosion for the higher incident ion masses (Kr and Xe).

After properly taking into account their respective artifacts, the results of all methods are compatible with each other, with EELS and GI-XRF combined with etching providing similar spatial resolution on the nanometer scale for the dopant profile. The sheet concentration of the piled-up As at the interface was found to be similar to 1 x 10(15) cm(-2) for an implanted dose of I X 1016 cm-2 with a maximum concentration of similar to 10 at. %. The strain observed in the Z-contrast images also suggests a significant concentration of local distortions within 3 nm from the interface, which, however, do not seem to involve intrinsic point defects.

X-ray diffraction confirmed the reasonable crystalline quality of the films with a full width at half maximum of 0.58 degrees in omega (004 reflection), 0.80 degrees in phi (222 reflection), and 0.28 degrees in theta. The epitaxial thin films of BiScO(3) on SrTiO(3) retain the principal structural features of bulk BiScO(3) (i.e., octahedral tilting and the pattern of Bi displacements) that give rise to a pseudo-orthorhombic unit cell 2 root 2a(c) x root 2a(c) x 4a(c) (a(c) approximate to 4 angstrom refers to the lattice parameter of an ideal cubic perovskite). Films grown on {100} substrates adopt the bulk monoclinic structure, whereas films on the (110) substrates appear to exhibit an orthorhombic symmetry. The dielectric permittivities were modest (approximate to 30) with low loss tangents (<1% at low fields); no maxima were observed over a temperature range of -200 to +350 degrees C. There is no evidence of significant hysteresis (either ferroelectric or antiferroelectric) at room temperature up to the breakdown strength of the films. (C) 2008 American Institute of Physics.

Madireddi, Sesha TI Simulations of remanence and field distributions of permanent magnet array with rectangular cavity SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID REFRIGERATION SYSTEMS; DESIGN AB The magnetic phenomena of a Halbach-type permanent magnet array under a strong self-field such as demagnetization, saturation, deflection, and rotation of remanence vectors occur deep in the interior of the magnets, and thus lead to an inhomogeneous field even for a hollow cylindrical permanent magnet array with circular cavity. Considering the anisotropic magnetization loops of commercially available permanent magnets, the self-consistent remanence and field distributions of a 16 piece hollow cylindrical permanent magnet array with rectangular cavity (HCPMARC) are presented here to simulate the magnetic phenomena inside the magnets. The field distribution of a HCPMARC can be modulated by array structure while keeping both the cross sectional areas of the cavity and the magnets constant. At the expense of field uniformity, a HCPMARC acquires greater center field uniformity than a HCPMACC does. Furthermore, we simulated the magnetization and field distributions for a yoked HCPMARC obtained by replacing the partial permanent magnets with soft ones on both magnetic poles of a yokeless HCPMARC. Such substitution always enhances field uniformity but depresses the center field. This, in turn, causes changes in the average magnitude of the field in the entire rectagular cavity.

For Er(2)Hf(2)O(7) the defect fluorite structure is predicted to be more stable than pyrochlore structure, agreeing well with previous experimental [J. Inorg. Nucl. Chem. 31, 2367 (1969); J. Less Common Met. 14, 435 (1968)] and theoretical [J. Am. Ceram. Soc. 85, 2139 (2002)] investigations. In contrast to Er(2)Hf(2)O(7) pyrochlore, Dy(2)Hf(2)O(7) and Ho(2)Hf(2)O(7) prefer pyrochlore structures, which is consistent with the recent experimental observations of Dy(2)Hf(2)O(7) compound [J.

TI Crystal structure of the lysine riboswitch regulatory mRNA element SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID GENE-EXPRESSION; RECOGNITION; MOTIF; BIOSYNTHESIS; MECHANISMS; SCATTERING; BACTERIA; ANALOGS; TARGETS; LIGAND AB Riboswitches are metabolite-sensitive elements found in mRNAs that control gene expression through a regulatory secondary structural switch. Along with regulation of lysine biosynthetic genes, mutations within the lysine-responsive riboswitch (L-box) play a role in the acquisition of resistance to antimicrobiallysine analogs. To understand the structural basis for lysine binding, we have determined the 2.8 angstrom resolution crystal structure of lysine bound to the Thermotoga maritima asd lysine riboswitch ligand-binding domain. The structure reveals a complex architecture scaffolding a binding pocket completely enveloping lysine. Mutations conferring antimicrobial resistance cluster around this site as well as highly conserved long range interactions, indicating that they disrupt lysine binding or proper folding of the RNA. Comparison of the free and bound forms by x-ray crystallography, small angle x-ray scattering, and chemical probing reveals almost identical structures, indicating that lysine induces only limited and local conformational changes upon binding.

We identified possible reaction paths for the HCOO decomposition (or synthesis) and hydrogenation in the presence of a co-adsorbed H atom without assuming their final states. Starting from the most stable bidentate HCOO adsorption configuration, we calculated the pre-exponential factors and reaction rates of the identified HCOO reaction and diffusion paths using harmonic transition state theory. In agreement with previous experimental and theoretical studies, we found that HCOO was formed by gaseous CO2 and adsorbed H through the Eley-Ricleal (ER) mechanism. The activation barriers for direct HCOO synthesis from CO via the ER and Langmuir-Hinshelwood (LH) mechanisms were 1.44 and 2.45 eV, respectively, suggesting that the reaction pathways CO or CO(g) + OH <-> HCOO were unfavorable on the Cu(III) surface. The decomposition of HCOO to HCO + O was much slower than its reverse recombination. This indicated that the reaction pathway from HCOO to HCO also was unlikely. On the other hand, the reaction route for HCOO hydrogenation to H2COO in the presence of a co-adsorbed H atom had an activation energy of 1.24 eV, suggesting that HCOO hydrogenation was competitive with HCOO decomposition via the ER mechanism with a barrier of 1.30 eV. Except for two fast HCOO diffusion processes, our results showed that HCOO <-> CO2(g) + H and HCOO + H <-> H2COO were the dominant reaction pathways on the Cu(III) surface. (C) 2008 Elsevier Inc.

Initial data-dependent LC-MS/MS analyses of human plasma, erythrocyte, and lymphocyte lipids were performed in order to identify lipid molecular species in conjunction with complementary accurate mass and isotopic distribution information. Identified lipids were used to populate initial lipid AMT tag databases containing 250 and 45 entries for those species detected in positive and negative electrospray ionization (ESI) modes, respectively. The positive ESI database was then utilized to identify human plasma, erythrocyte, and lymphocyte lipids in high-throughput LC-MS analyses based on the AMT tag approach. We were able to define the lipid profiles of human plasma, erythrocytes, and lymphocytes based on qualitative and quantitative differences in lipid abundance. (C) 2008 Published by Elsevier B.V.

If the interface is curved, however, discretization generally leads to adjoining surfaces that do not coincide spatially. Straightforward Lagrange multiplier methods lead to discrete formulations failing a first-order patch test [T.A. Laursen, M.W Heinstein, Consistent mesh-tying methods for topologically distinct discretized surfaces in non-linear solid mechanics, Internat. J. Nhumer. Methods Eng. 57 (2003) 1197-1242]. This paper presents a theoretical and computational study of a least-squares method for mesh tying [P. Bochev, D.M. Day, A least-squares method for consistent mesh tying, Internal. J. Numer. Anal. Modeling 4 (2007) 342-352], applied to the partial differential equation del(2)phi + alpha phi = f. We prove optimal convergence rates for domains represented as overlapping subdomains and show that the least-squares method passes a patch test of the order of the finite element space by construction. To apply the method to subdomain configurations with gaps and overlaps we use interface perturbations to eliminate the gaps. Theoretical error estimates are illustrated by numerical experiments.

Many misfit dislocations were redirected from the Al/Si interface and propagated to the Si substrate due to the formation of He bubbles in the substrate. Growth temperature of GaN/AlN was chosen to be the annealing temperature necessary for He bubble formation. The dependence on the He fluence, distance of He bubbles from the Si surface and cleaning procedure of the Si before growth have been described. The structural perfection of the GaN/AlN layers was compared to the layers grown on un-implanted Si. (c) 2008 Published by Elsevier B.V.
