( 2005) presented a combined parameter and state estimation method, entitled SODA, to improve the treatment of input, output, parameter and model structural error during model calibration. The argument for using SODA is that explicit treatment of all sources of uncertainty should result in parameter estimates that closer represent system properties, instead of parameter values that are compensating for input, output and model structural errors. In this study we provide further support for this claim by applying the SODA method to the calibration of a simple 2- parameter snow model, using data from the Lake Eldora SNOwpack TELemetry ( SNOTEL) site in Colorado, USA.

We demonstrate that symmetric counterflowing Jets with identical mass flow rates exhibit multiple steady states and, in certain cases, time-dependent (periodic) steady states. Two geometric configurations were studied based on the inlet jet shapes: planar and axisymmetric. Stagnation flows formed by planar counterflowing jets exhibit both steady-state multiplicity and time-dependent behaviour, while axisymmetric jets exhibit only a steady-state multiplicity. A linearized bifurcation and stability analysis based on the continuity and Navier-Stokes equations revealed transitions between a single (symmetric) steady state and multiple steady states or periodic steady states. The dimensionless quantities forming the parameter space of this system are the inlet Reynolds number (Re) and a geometric aspect ratio (alpha), equal to the jet inlet characteristic length (used for calculating Re) divided by the jet separation. The boundaries separating different flow regimes have been identified in the (Re, alpha) parameter space. The resulting flow maps are useful for the design and operation of counterflow jet reactors.

To describe the constitutive relationships between water saturation, capillary pressure, and phase relative permeability, the widely used van Genuchten model and Parker and Lenhard models are adopted. The log-transformed intrinsic permeability, soil pore size distribution, and van Genuchten fitting parameter n are treated as normally distributed stochastic variables with a separable exponential covariance model. The perturbation part of these three log-transformed variables is decomposed via Karhunen-Loeve expansion. The dependent variables (phase pressure, phase mobility, and capillary pressure) are expanded by polynomial expansions and the perturbation method. Incorporating these expansions of random soil properties variables and dependent variables into the governing equations yields a series of differential equations in different orders. We construct the moments of the dependent variables from the solutions of these differential equations. We demonstrate the stochastic model with two-dimensional examples of transient two-phase flow. We also conduct Monte Carlo simulations using the finite element heat and mass (FEHM) transfer code, whose results are considered "true" solutions. The match between the results from FEHM and KLME indicates the validity of the proposed KLME application in transient two-phase flow. The computational efficiency of the KLME approach over Monte Carlo methods is at least an order of magnitude for transient two-phase flow problems.

The AMS provides real time information on mass concentration and composition of the non-refractory species in particulate matter less than 1 mu m (NR-PM1) with high time and size-resolution. In order to account for the refractory material in the aerosol, we also present estimates of Black Carbon (BC) using an aethalometer and an estimate of the aerosol soil component obtained from Proton-Induced X-ray Emission Spectrometry (PIXE) analysis of impactor substrates. Comparisons of AMS + BC + soil mass concentration with other collocated particle instruments (a LASAIR Optical Particle Counter, a PM2.5 Tapered Element Oscillating Microbalance (TEOM), and a PM2.5 DustTrak Aerosol Monitor) show that the AMS + BC + soil mass concentration is consistent with the total PM2.5 mass concentration during MCMA-2003 within the combined uncertainties. In Mexico City, the organic fraction of the estimated PM2.5 at CENICA represents, on average, 54.6% (standard deviation sigma=10%) of the mass, with the rest consisting of inorganic compounds ( mainly ammonium nitrate and sulfate/ammonium salts), BC, and soil. Inorganic compounds represent 27.5% of PM2.5 (sigma=10%); BC mass concentration is about 11% (sigma=4%); while soil represents about 6.9% (sigma=4%). Size distributions are presented for the AMS species; they show an accumulation mode that contains mainly oxygenated organic and secondary inorganic compounds. The organic size distributions also contain a small organic particle mode that is likely indicative of fresh traffic emissions; small particle modes exist for the inorganic species as well. Evidence suggests that the organic and inorganic species are not always internally mixed, especially in the small modes. The aerosol seems to be neutralized most of the time; however, there were some periods when there was not enough ammonium to completely neutralize the nitrate, chloride and sulfate present. The diurnal cycle and size distributions of nitrate suggest local photochemical production. On the other hand, sulfate appears to be produced on a regional scale. There are indications of new particle formation and growth events when concentrations of SO2 were high. Although the sources of chloride are not clear, this species seems to condense as ammonium chloride early in the morning and to evaporate as the temperature increases and RH decreases. The total and speciated mass concentrations and diurnal cycles measured during MCMA-2003 are similar to measurements during a previous field campaign at a nearby location.

Here we report the crystal structures of the zinc-finger ubiquitin binding domain (ZnF UBP) from the deubiquitinating enzyme isopeptidase T (IsoT, or USP5) alone and in complex with ubiquitin. Unlike other ubiquitin binding domains, this domain contains a deep binding pocket where the C-terminal diglycine motif of ubiquitin is inserted, thus explaining the specificity of IsoT for an unmodified C terminus on the proximal subunit of polyubiquitin. Mutations in the domain demonstrate that it is required for optimal catalytic activation of IsoT. This domain is present in several other protein families, and the ZnF UBP domain from an E3 ligase also requires the C terminus of ubiquitin for binding. These data suggest that binding the ubiquitin C terminus may be necessary for the function of other proteins. C1 Brookhaven Natl Lab, Dept Biol, Upton, NY 11794 USA.

Deviations from these physics-based constraints are interpreted as arising from measurement errors. Two million ion spectra from the Solar Wind Experiment Faraday Cup instruments on the Wind spacecraft are used as a case study. The accuracy of velocity measurements is determined by the fact that differential flow between hydrogen and helium should be aligned with the ambient magnetic field. Modeling the breakdown of field alignment suggests velocity uncertainties are less than 0.16% in magnitude and 3 degrees in direction. Temperature uncertainty is found by examining the distribution of observed temperature anisotropies in high-beta solar wind intervals where the firehose, mirror, and cyclotron microinstabilities should drive the distribution to isotropy. The presence of a finite anisotropy at high beta suggests overall temperature uncertainties of 8%. Hydrogen and helium number densities are compared with the electron density inferred from observations of the local electron plasma frequency as a function of solar wind speed and year. We find that after accounting for the contribution of minor ions, the results are consistent with a systematic offset between the two instruments of 3-4%. The temperature and density methods are sensitive to non-Maxwellian features such as heat flux and proton beams and as a result are more suited to slow solar wind where these features are rare. These procedures are of general use in identifying the accuracy of observations from any solar wind ion instrument. C1 MIT, Kavli Inst Astrophys & Space Res, Cambridge, MA 02139 USA.

Thus, these neurotoxins became widely used tools for investigating vesicular trafficking routes. Except for VAMP-1, VAMP-2, and Cellubrevin, no other member of the VAMP family represents a substrate for these neurotoxins. The molecular basis for this discrepancy is not known. A 34 amino acid residue segment of VAMP-2 was previously suggested to mediate the interaction with botulinum neurotoxin B, but the validity of the data was later questioned. To check whether this segment alone controls the susceptibility toward botulinum neurotoxin B, it was used to replace the corresponding segment in TI-VAMP. The resulting VAMP hybrid and VAMP-2 were hydrolysed at virtually identical rates. Resetting the VAMP-2 portion in the hybrid from either end to TI-VAMP residues gradually reduced the cleavability. A hybrid encompassing merely the VAMP-2 segment 71-80 around the Gln76/Phe77 scissile bond was still hydrolysed, albeit at a similar to tenfold lower cleavage rate. The contribution of each non-conserved amino acid of the whole 34-mer segment to the interaction was investigated employing VAMP-2. We find that the eight non-conserved residues of the 71-80 segment are all necessary for efficient cleavage. Mutation of an dditional six residues located upstream and downstream of this segment affects substrate hydrolysis as well. Vice versa, a readily cleavable TI-VAMP molecule requires at the least the replacement of Ile158, Thr161, and the section 165-174 by Asp64, Ala67, and the 71-80 segment of VAMP-2, respectively. However, the insensitivity of TI-VAMP to botulinum neurotoxin B relies on at least 12 amino acid changes versus VAMP-2. These are scattered along an interface of 22 amino acid residues in length.

In the low temperature (T < T-coh similar to 40 K) Fermi liquid state, however, a new peak in the scattering occurs at E-2 approximate to 33 meV, which lies in the hybridization gap that exists in this compound. We report inelastic neutron scattering results for a single-crystal sample. The scattering at energies near E-1 qualitatively has the momentum (Q) dependence expected for interband scattering across the indirect gap. The scattering near E-2 has a very different Q dependence: it is a weak function of Q over a large fraction of the Brillouin zone and is smallest near (1/2,1/2,1/2). A possibility is that the peak at E-2 arises from a spatially localized excitation in the hybridization gap. C1 Univ Calif Irvine, Irvine, CA 92697 USA. Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

The multiplet structures with cubic symmetry are qualitatively reproduced by calculations for an atomiclike d(5) configuration in tetrahedral environment, and show zero anisotropy in the orbital and spin moments within the experimental uncertainty. However, hybridization with the host valence bands is reflected by the presence of a preedge feature with a uniaxial anisotropy and a marked dependence on the hole density.

Over the investigated pressure range, we find a significant decrease in the H-point phonon anomaly. We also present calculations based on density functional theory that accurately predict this pressure dependence. Based on these results, we infer that the likely explanation for the H-point anomaly in molybdenum is strong electron-phonon coupling, which decreases upon compression due to the shift of the Fermi level with respect to the relevant electronic bands.

We recorded the signature of the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state for all pressures when H parallel to ab. Also remarkably, the FFLO regime suddenly expands for P=1.34 GPa. With the help of a microscopic theory for d-wave superconductivity, we have extracted the gyromagnetic ratio g and the Fermi velocities v(a) and v(c). Our study is the first evidence for the existence of the FFLO state away from the influence of the antiferromagnetic fluctuations. We find a close parallel between the T-P phase diagram of CeCoIn5 and the T-x phase diagram of the high-T-c cuprates, where x is the hole concentration.

The dynamics of a charge-neutral, narrow, electron-positron jet propagating through an unmagnetized electron-ion plasma was investigated using a three-dimensional, electromagnetic, particle-in-cell computer code. The interaction excited magnetic filamentation as well as electrostatic plasma instabilities. In some cases, the longitudinal electric fields generated inductively and electrostatically reached the cold plasma-wave-breaking limit, and the longitudinal momentum of about half the positrons increased by 50% with a maximum gain exceeding a factor of 2 during the simulation period. Particle acceleration via these mechanisms occurred when the criteria for Weibel instability were satisfied. C1 Stanford Univ, Stanford Linear Accelerator Ctr, Stanford, CA 94309 USA.

A realistic effective Hamiltonian is derived from novel Wannier state analysis of the electronic structure. Surprisingly, e-l interaction (similar or equal to 0.9 eV) alone is found insufficient to stabilize the orbital ordered state. On the other hand, e-e interaction (similar or equal to 1.7 eV) not only induces orbital ordering, but also greatly facilitates the Jahn-Teller distortion via enhanced localization. Further experimental means to quantify the competition between these two mechanisms are proposed. C1 Brookhaven Natl Lab, Dept Phys, Upton, NY 11973 USA.

Although many organisms retreated to anoxic environments, others evolved to use oxygen as a. high-potential redox couple white concomitantly mitigating its toxicity. To understand the changes in biochemistry and enzymology that accompanied adaptation to O-2, we integrated network analysis with information on enzyme evolution to infer how oxygen availability changed the architecture of metabolic networks. Our analysis revealed the existence of four discrete groups of networks of increasing complexity, with transitions between groups being contingent on the presence of key metabolites, including molecular oxygen, which was required for transition into the largest networks.

The genetic variability between phenotypically distinct strains that differ by less that 1% in 16S ribosomal RNA sequences occurs mostly in genomic islands. Island genes appear to have been acquired in part by phage-mediated lateral gene transfer, and some are differentially expressed under light and nutrient stress. Furthermore, genome fragments directly recovered from ocean ecosystems indicate that these islands are variable among co-occurring Prochlorococcus cells. Genomic islands in this free-living photoautotroph share features with pathogenicity islands of parasitic bacteria, suggesting a general mechanism for niche differentiation in microbial species.

To better understand the impacts of cropland management practices, we used the NCAR CAM3 general circulation model coupled to a slab-ocean model to simulate climate change under extreme scenarios of irrigation, tillage, and crop productivity. Compared to a control scenario, increases in irrigation and leaf area index and reductions in tillage all have a physical cooling effect by causing increases in planetary albedo. The cooling is most pronounced for irrigation, with simulated local cooling up to similar to 8 degrees C and global land surface cooling of 1.3 degrees C. Increases in soil albedo through reduced tillage are found to have a global cooling effect ( similar to 0.2 degrees C) comparable to the biogeochemical cooling from reported carbon sequestration potentials. By identifying the impacts of extreme scenarios at local and global scales, this study effectively shows the importance of considering different aspects of crop management in the development of climate models, analysis of observed climate trends, and design of policy intended to mitigate climate change.

Here we report the biochemical characterization on the second generation inhibitor (+)-1 (L-869298, IC50 = 0.4 nM) and its enantiomer (-)-1 (L-869299, IC50 = 43 nM) and their cocrystal structures with PDE4D at 2.0 angstrom resolution. Despite the 107-fold affinity difference, both enantiomers interact with the same sets of residues in the rigid active site. The weaker (-)-1 adopts an unfavorable conformation to preserve the pivotal interactions between the Mg-bound waters and the N-oxide of pyridine. These structures support a model in which inhibitors are anchored by the invariant glutamine at one end and the metal-pocket residues at another end. This model provides explanations for most of the observed structure-activity relationship and the metal ion dependency of the catechol-ether based inhibitors and should facilitate their further design.

N-2 A(3)Sigma(u)(+) is generated from the quenching of resonantly excited xenon in a mixture of xenon, N-15(2), and N-14(2) that is illuminated with xenon resonant lamps (147 nm). Mass spectra are periodically taken of the mixture. Over time, we observe significant isotopic scrambling of the N-15(2) and N-14(2), generating (NN)-N-15-N-14 in concentrations approaching 10% (similar to 2 Tort) of the initial N-15(2) concentration. Though we do not observe the direct formation of N-4, the isotopic ratios indicate that an excited complex (N-15(2) N-14(2)) exists long enough so that scrambling of the nitrogen atoms can occur, offering a possible route to the formation of tetrahedral nitrogen (T-1(d) N-4).

Here we examine an alternative model in which the ammoniated electron is regarded as a solvent stabilized multimer radical anion in which most of the excess electron density resides in the frontier orbitals of N atoms in the ammonia molecules forming the solvation cavity. The cavity is formed due to the repulsion between negatively charged solvent molecules. Using density functional theory calculations, we demonstrate that such core anions would semiquantitatively account for the observed pattern of Knight shifts for H-1 and N-14 nuclei observed by NMR spectroscopy and the downshifted stretching and bending modes observed by infrared spectroscopy. We speculate that the excess electrons in other aprotic solvents might be, in this respect, analogous to the ammoniated electron, with substantial transfer of the spin density into the frontier N and C orbitals of methyl, amino, and amide groups.

Optimum geometries and harmonic vibrational frequencies were determined at the B3LYP level of theory using basis sets of triple-zeta quality including polarization and diffuse functions. Heats of formation were obtained from isogyric reaction energies computed at the CCSD(T) level of theory using large basis sets and including corrections for core-valence correlation, scalar relativistic effects, and basis set incompleteness. Additionally, polynomial fits were performed for the heat capacity and the standard enthalpy and entropy over the 100-3000 K temperature range. While our computed heats of formation agree well with previously obtained experimental data for some of these species, our results suggest that revision of the experimental data for others may be appropriate.

Chem. Phys. 2002, 116, 5115], which allows for condensed-phase simulations. The revised version (TTM2.1-F) of the potential correctly describes the individual water molecular dipole moment and alleviates problems arising at short intermolecular separations that can be sampled in the course of molecular dynamics and Monte Carlo simulations of condensed environments. Furthermore, its parallel implementation under periodic boundary conditions enables the efficient calculation of the macroscopic structural and thermodynamic properties of liquid water, as its performance scales superlinearly with up to a number of 64 processors for a simulation box of 512 molecules. We report the radial distribution functions, average energy, internal geometry, and dipole moment in the liquid as well as the density, dielectric constant, and self-diffusion coefficient at T = 300 K from (NVT) and (NPT) classical molecular dynamics simulations by using the revised version of the potential.

The pump, Stokes, and probe pulses are all selected inside a single broadband ultrafast pulse by a phase- and polarization-controlled pulse shaping technique and used to generate two spectral interference CARS signals simultaneously. The normalized difference of these two signals provides an amplified background-free broadband resonant CARS spectrum over the 400-1500 cm(-1) range with 35 cm(-1) spectral resolution. Chemically selective microscopy images of multicomponent polymer and liquid samples are investigated with this new CARS method. Multiplex CARS spectra at 10 000 spatial points are measured within a few minutes, and used to construct chemically selective microscopy images with a spatial resolution of 400 nm. The spectral bandwidth limits, sensitivity, homodyne amplification advantages, spatial resolution, depolarization, chromatic aberration, and chemical imaging aspects of this new technique are discussed in detail.

Marked changes in the liquid water XAS are observed upon addition of the various monovalent cation chlorides that are nearly independent of the identity of the cation. This indicates that interactions with the dissolved monovalent cations do not significantly perturb the unoccupied molecular orbitals of water molecules in the vicinity of the cations and that water-chloride interactions are primarily responsible for the observed spectral changes. In contrast, the addition of the divalent cations engenders changes unique from the case of the monovalent cations, as well as from each other. Density functional theory calculations suggest that the ion-specific spectral variations arise primarily from direct electronic perturbation of the unoccupied orbitals due to the presence of the ions, probably as a result of differences in charge transfer from the water molecules onto the divalent cations.

For bioapplications QDs must be water-soluble and buffer stable, making their synthesis challenging and time-consuming. A simple aqueous synthesis of silica-capped, highly fluorescent CdTe quantum dots has been developed. CdTe QDs are advantageous as the emission can be tuned to the near-infrared where tissue absorption is at a minimum, while the silica shell can prevent the leakage of toxic Cd2+ and provide a surface for easy conjugation to biomolecules Such as proteins. The presence of a silica shell of 2-5 nm in thickness has been confirmed by transmission electron microscopy and atomic force microscopy measurements. Photoluminescence studies show that the silica shell results in greatly increased photostability in Tris-borate-ethylenediaminetetraacetate and phosphate-buffered saline buffers. To further improve their biocornpatibility, the silica-capped QDs have been functionalized with poly(ethylene glycol) and thiol-terminated biolinkers. Through the use of these linkers, antibody proteins were successfully conjugated as confirmed by agarose gel electrophoresis. Streptavidin-maleimide and biotinylated polystyrene microbeads confirmed the bioactivity and conjugation specificity of the thiolated QDs. These functionalized, silica-capped QDs are ideal labels, easily synthesized, robust, safe, and readily conjugated to biomolecules while maintaining bioactivity. They are potentially useful for a number of applications in biolabeling and imaging. C1 Univ Calif Santa Cruz, Dept Chem & Biochem, Santa Cruz, CA 95064 USA.

The molecular natures and identities of coupling proteins that allow microtubule depolymerization to pull chromosomes to poles during anaphase have long remained elusive(1). In budding yeast, the ten-protein Dam1 complex is a critical microtubule-binding component of the kinetochore(2) that oligomerizes into a 50-nm ring around a microtubule in vitro(3,4). Here we show, with the use of a real-time, two-colour fluorescence microscopy assay, that the ring complex moves processively for several micrometres at the ends of depolymerizing microtubules without detaching from the lattice. Electron microscopic analysis of 'end-on views' revealed a 16-fold symmetry of the kinetochore rings. This out-of-register arrangement with respect to the 13-fold microtubule symmetry is consistent with a sliding mechanism based on an electrostatically coupled ring-microtubule interface. The Dam1 ring complex is a molecular device that can translate the force generated by microtubule depolymerization into movement along the lattice to facilitate chromosome segregation.

The LK14 peptide, adsorbed from a pH 7.4 phosphate-buffered saline (PBS) solution, displayed very different coverage, surface roughness and friction, topography, and surface-induced orientation when adsorbed onto PS versus SiO2 surfaces. Real-time QCM adsorption data revealed that the peptide adsorbed onto hydrophobic PS through a fast (t < 2 min) process, while a much slower (t > 30 min) multistep adsorption and rearrangement occurred on the hydrophilic SiO2. AFM measurements showed different surface morphologies and friction coefficients for LK14 adsorbed on the two surfaces. Surface-specific SFG spectra indicate very different ordering of the adsorbed peptide on hydrophobic PS as compared to hydrophilic SiO2. At the LK14 solution/PS interface, CH resonances corresponding to the hydrophobic leucine side chains are evident. Conversely, only NH modes are observed at the peptide solution/SiO2 interface, indicating a different average molecular orientation on this hydrophilic surface. The surface-dependent difference in the molecular-scale peptide interaction at the solution/hydrophobic solid versus solution/hydrophilic solid interfaces (measured by SFG) is manifested as significantly different macromolecular-level adsorption properties on the two surfaces (determined via AFM and QCM experiments).

DFT calculations using the Perdew-Burke-Ernzerhof exchange correlation functional correctly predict the palladium porphine (PdP) low-spin ground state. PdP is found to adsorb preferentially on gold in a flat geometry, not in an edgewise geometry, in qualitative agreement with experiments on substituted porphyrins. It exhibits no covalent bonding to Au(111), and the binding energy is a small fraction of an electronvolt. The DFT+U technique, parametrized to B3LYP-predicted spin state ordering of the Mn cl-electrons, is found to be crucial for reproducing the correct magnetic moment and geometry of the isolated manganese porphine (MnP) molecule. Adsorption of Mn(II)P on Au(111) substantially alters the Mn ion spin state. Its interaction with the gold substrate is stronger and more site-specific than that of PdP. The binding can be partially reversed by applying an electric potential, which leads to significant changes in the electronic and magnetic properties of adsorbed MnP and similar to 0.1 angstrom changes in the Mn-nitrogen distances within the porphine macrocycle. We conjecture that this DFT+U approach may be a useful general method for modeling first-row transition metal ion complexes in a condensed-matter setting.

This is due to the well-known phase problem of X-ray diffraction. Here we successfully applied the multiwavelength anomalous dispersion (MAD) method to solve the phase problem for an inverted hexagonal phase of a phospholipid with brominated chains. Although the principle of the MAD method for all systems is the same, we found that for lipid structures it is necessary to use a procedure of analysis significantly different from that used for protein crystals. The inverted hexagonal phase has been used to study the chain packing in a hydrophobic interstice where three monolayers meet. Hydrophobic interstices are of great interest, because they occur in the intermediate states of membrane fusion. It is generally believed that chain packing in such a region is energy costly. Consequently, it has been speculated that the inverted lipid tube is likely to deviate from a circular shape, and the chain density distribution might be nonuniform. The bromine distribution obtained from the MAD analysis provides the information for the chain packing in the hexagonal unit cell. The intensity of the bromine distribution is undulated around the unit cell. The analysis shows that the lipid chains pack the hexagonal unit cell at constant volume per chain, with no detectable effect from a high-energy interstitial region.

From this initial capital of matter, differentiation formed the chemical and physical compartments of core, mantle, continents, ocean and atmosphere, that characterize Earth today. Differentiation was, and still is, driven by energy from various sources including radioactive heat and relic heat from accretion. With evolution of photosynthesis, living organisms acquired the ability to harvest Solar energy and channel it into geochemical cycles. Oil our present Earth, the primary production from life contributes 3 times more energy to these cycles than Earth's internal heat engine. We hypothesize that the emergence of this energy resource modified Earth's geochemical cycles and ultimately stimulated the production of granite during the earliest Archaean, which led to the first stabilization of continents oil Earth. Such biological forcing may explain the unique presence of granite oil Earth, and why stable continents did not form during the first half billion years of Earth's history. (c) 2006 Elsevier B.V.

All polymers have more than one disordering transition between the glass transition (between 400 and 430 K) and decomposition (between 7 10 and 750 K). The first transition in PHBA at 616-633 K is from orthorhombic rigid crystals to a conformationally disordered pseudo-hexagonal phase (condis phase). The two higher transitions are first, a further disordering process to a hexagonal condis crystal, and then a change to an anisotropic melt (liquid crystal) at about 800 K, with increasing decomposition above 750 K. In PHNA, orthorhombic crystals change above 600 K to an orthorhombic condis crystal structure, which go to an anisotropic melt at 750 K, and subsequent decomposition. In addition, using empirical entropy rules that account for the changes during the transitions from the crystal to the disordered mobile phases, an effort is made to understand the disorder and mobility, and to arrive at a non-equilibrium phase diagram of the copolymer system. The existence of a single, but up to 200 K wide, glass transition and remaining high crystallinity of the copolyesters, indicate partial solubility of the repeating units in all phases. The new data are compared to and brought into agreement with the large number of prior measurements and often unclear interpretations. (c) 2006 Elsevier Ltd. All rights reserved.

An IR source could induce the same green CTVE-recombination luminescence band as that by a UV pumping. This up-conversion luminescence is characterized by a relaxation time tau (tau similar to 60 s at 3 K), and theoretically explained as a result of IR-induced transfer of occupation of a metastable anharmonic CTVE state into a harmonic luminescent CTVE state. The observed temperature dependence of tau suggests that the relaxation is controlled by resonant and phonon-induced tunneling processes. (c) 2006 Elsevier B.V. All rights reserved.

The structure of each has been determined by single-crystal X-ray diffraction using Mo K alpha. radiation and a charge-coupled device area detector. Both structures are monoclinic with space group C2/c.

During the winter months of increased anthropogenic pollution we observe smaller sizes of cloud droplets in water clouds in agreement with the expected aerosol indirect effect. However, contrary to our expectations, we find that during episodes of increased pollution the effective radius of ice crystals is shifted toward the larger rather than smaller sizes. We propose a combination of natural seasonal variability of meteorological conditions and an "inverse aerosol indirect effect" caused by heterogeneous ice nucleation as a possible explanation of observed ice crystal growth. The ECHAM4 (European Center for Medium-Range Weather Forecast Hamburg version 4th generation GCM) results with heterogeneous ice nucleation reproduce the observed increase in ice crystal size during the enhanced pollution episodes.

The perfect-pairing approximation is used to obtain a simple reference wave function which can qualitatively describe bond breaking, diradicals, and other highly correlated systems, and the perturbative correction accounts for the dynamical correlation. An efficient implementation of this correction using the resolution of the identity approximation enables PP(2) to be computed at a cost only a few times larger than that of canonical MP2 for systems with hundreds of active electrons and tens of heavy atoms. PP(2) significantly improves on MP2 predictions in various systems with a challenging electronic structure. (c) 2006 American Institute of Physics.

The isopropyl radicals so produced have internal energies of similar to 0.3-2.0 eV. Images recorded for photoionization energies from just below the adiabatic ionization threshold at 7.37 +/- 0.02 and 8.04 eV are essentially identical both to each other and to that recorded at 9.67 eV. These results imply that the photoionization cross section is only weakly dependent on internal energy. Several factors contributing to this observation are discussed, as are the implications for the photoionization of other systems with significant internal excitation.

The effect of the incident collision energy on the phase of vapor deposited water films and their subsequent crystallization kinetics are studied using temperature programed desorption and infrared spectroscopy. We find that for films deposited at substrate temperatures below 110 K, the incident kinetic energy (up to 205 kJ/mole) has no effect on the initial phase of the deposited film or its crystallization kinetics. Above 110 K, the substrate temperature does affect the phase and crystallization kinetics of the deposited films but this result is also independent of the incident collision energy. The presence of a crystalline ice template (underlayer) does affect the crystallization of amorphous solid water, but this effect is also independent of the incident beam energy. These results suggest that the crystallization of amorphous solid water requires cooperative motion of several water molecules. (c) 2006 American Institute of Physics.

Chem. Phys. 79, 926 (1983)] utilizing classical and quantum statistical mechanics. The quantum statistical mechanical treatment generally resulted in lower liquid densities and higher vapor densities, narrowing the phase envelope. As a result, the calculated critical temperatures and normal boiling points were lower from the quantum simulations than the classical by 22 and 17 K, respectively, but the critical densities were equal within the estimated uncertainties. When the phase diagram from the quantum statistical mechanical treatment was increased by 22 K, it agreed with the classical results quite well throughout the entire simulated temperature range. A semiclassical treatment, involving a low order expansion in Planck's constant, resulted in good agreement with the path integral results for second virial coefficients, but gave densities and vapor pressures that fluctuated between the values for the classical and quantum statistical mechanics values, with no definite agreement with either.

The adsorptions were conducted from aqueous solutions to an uncharged, hydrophobic octadecyltrichlorosilane (OTS) surface, which is highly selective for the hydrophobic PtBS block. The star-block copolymer adsorption kinetics scale linearly with concentration over the entire adsorption process and follow behavior characteristic of random sequential adsorption (RSA). At long times, the star-blocks approach a jamming limit with t(-1/2) kinetics. The micelles, in contrast, show no sign of a jamming limit and adsorb according to log(t) kinetics, signifying that the adsorbed layer is able to relax during the adsorption process. Furthermore, the rate of adsorption of the micelles scales nonlinearly with concentration at long times, indicating that the time scale of this relaxation is on the same order of magnitude as the characteristic adsorption time.

SO MODERN PHYSICS LETTERS A LA English DT Article DE ultra high energy neutrinos; Z-burst; neutrino astronomy ID ZATSEPIN-KUZMIN CUTOFF; NEUTRINO MASS; SPECTRUM; ABSORPTION; WMAP AB We show that the cascade limit on ultra high energy cosmic neutrino (UHEC nu) flux imposes a lower bound on the neutrino mass, provided that super-GZK events of ultra high energy cosmic rays (UHECRs) are produced from Z-bursts. Based on data from HiRes and AGASA, the lower bound obtained on neutrino mass violates its existing cosmological upper bound. We conclude that Z-bursts cannot be the dominant source for the observed super-GZK UHECR events. This is consistent with the recent ANITA-lite data.

Previously, cosmic magnification measurements have been seriously complicated by galaxy clustering. With precise redshifts obtained using the 21-cm emission line wavelength, one can correlate galaxies at different source planes, or exclude close pairs to eliminate such contamination. We provide forecasts for future surveys, specifically the Square Kilometer Array (SKA) and the Canadian Large Adaptive Reflector (CLAR). SKA can achieve similar to 1 per cent precision on the dark-matter power spectrum and the galaxy dark-matter cross-correlation power spectrum, while CLAR can measure an accurate cross-correlation power spectrum. The neutral hydrogen fraction was most likely significantly higher at high redshifts, which increases the number of observed galaxies significantly, such that CLAR can also measure the dark-matter lensing power spectrum. SKA can also allow precise measurement of bispectrum lensing. C1 NASA, Fermilab Astrophys Grp, Fermi Natl Accelerator Lab, Batavia, IL 60510 USA.

For GRB 050709 (the duration of which was 0.07 s), we identify two kinds of models: (i) a high-density solution, where the ejecta are collimated in a jet of half-angle theta(jet) > 6. and interact with a medium of particle density 10(-4) < n < 0.1 cm(-3); and (ii) a low-density solution with theta(jet) > 2 degrees and n < 10(-5) cm(-3). These density ranges are compatible with those expected in the vicinity of the host galaxy and in the intergalactic medium, lending support to the hypothesis that the progenitor of GRB 050709 is a neutron star-neutron star or neutron star-black hole merger. For GRB 050724 (which lasted 1.5 s), we obtain 0.1 < n < 10(3) cm(-3) and theta(jet) > 8 degrees. The range of allowed densities shows that this burst occurred in the interstellar medium. The dynamical parameters of the high-density model for the GRB afterglow 050709 are similar to those for 050724. If these parameters are representative for short-GRB outflows, then these jets are less collimated and have a lower kinetic energy than those of long bursts, which suggests that GRB jets are not magnetically collimated and are powered by the gravitational energy of the torus. Evidently, the analysis of more short-GRB afterglows is required for a more robust conclusion. C1 Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

In the case of the hole doped cuprates there is evidence which suggests that the important quantum degrees of freedom near the superconducting critical point are localized charge and spin density fluctuations. We argue that if these degrees of freedom are strongly coupled by spin-orbit interactions, a new type of quantum criticality arises with monopole-like quasiparticles as the important quantum degrees of freedom. In layered material this type of quantum criticality can be modeled using a 2-dimensional non-linear Schrodinger equation with an SU(N) gauge field. We exhibit a pairing wave function for quasi-particles that has topological order and anisotropic properties. The superconducting transition would in some respects resemble a KT transition.

There is a growing realization that air quality and climate change issues are strongly connected. To date, the importance of the coupling between O-3 and sulfate has not been fully appreciated, and thus regulations treat each pollutant separately. We show that emissions of O-3 precursors can dramatically affect regional sulfate air quality and climate forcing. At 2030 in an A1B future, increased O-3 precursor emissions enhance surface sulfate over India and China by up to 20% because of increased levels of OH and gas-phase SO2 oxidation rates and add up to 20% to the direct sulfate forcing for that region relative to the present day. Hence, O-3 precursors impose an indirect forcing via sulfate, which is more than twice the direct O-3 forcing itself (compare -0.61 vs. + 0.35 W/m(2)). Regulatory policy should consider both air quality and climate and should address O-3 and sulfate simultaneously because of the strong interaction between these species.

The structural model to be evaluated is dissected into small fragments via a sliding window, where each fragment is represented by a vector of multiple phi-psi angles. The sliding window ranges in size from a length of 1-10 phi-psi pairs (3-12 residues). In this method, the conformation of each fragment is scored based on the fit of multiple phi-psi angles of the fragment to a database of multiple phi-psi angles from high-resolution x-ray crystal structures. We show that measuring the fit of predicted structural models to the allowed conformational space of longer fragments is a significant discriminator for model quality. Reasonable models have higher-order phi-psi score fit values (m) > -1.00. C1 Lawrence Berkeley Natl Lab, Berkeley Struct Genom Ctr, Berkeley, CA 94720 USA.

When cells arrest proliferation, undergo apoptosis, or differentiate, distribution of nuclear proteins changes. Conversely, forced alteration of the distribution of nuclear proteins modifies cell phenotype. Immunostaining and fluorescence microscopy have been critical for such findings. However, there is increasing need for quantitative analysis of nuclear protein distribution to decipher epigenetic relationships between nuclear structure and cell phenotype and to unravel the mechanisms linking nuclear structure and function. We have developed imaging methods to quantify the distribution of fluorescently stained nuclear protein NuMA in different mammary phenotypes obtained using 3D cell culture. Automated image segmentation of DAPI-stained nuclei was generated to isolate thousands of nuclei from 3D confocal images. Prominent features of fluorescently stained NuMA were detected by using a previously undescribed local bright feature analysis technique, and their normalized spatial density was calculated as a function of the distance from the nuclear perimeter to its center. The results revealed marked changes in the distribution of the density of NuMA bright features when nonneoplastic cells underwent phenotypically normal acinar morphogenesis. Conversely, we did not detect any reorganization of NuMA during formation of tumor nodules by malignant cells. Importantly, the analysis also discriminated proliferating nonneoplastic from proliferating malignant cells, suggesting that these imaging methods are capable of identifying alterations linked not only to the proliferation status but also to the malignant character of cells. We believe that this quantitative analysis will have additional applications for classifying normal and pathological tissues.

Great progress has been made in all areas of ELTV lithography, including the crucial issue of fabrication of diffraction-limited optics. To gain an accurate understanding of the projection optic wavefront error in a completed lithography tool requires lithography-based aberration measurements; however, making such measurements in ELTV systems can be challenging. We describe the quantitative lithographic measurement of spherical aberration in a 0.3 numerical aperture. EUV microfield optic. The measurement method is based on use of the unique properties of a programmable coherence illuminator. The results show the optic to have 1 nm rms spherical error, whereas interferometric measurements performed during the alignment of the optic indicated a spherical error of less than 0.1 nm rms.

Verification that the signal resulted from NO was provided by tuning of the laser to a vibrational off-resonance wavelength that showed near-zero signal levels, which resulted from either fluorescence or interference at in-cylinder pressures of as much as 20 bar. The two-photon NO LIF signal showed good qualitative agreement with NO exhaust-gas measurements obtained over a wide range of engine loads. (c) 2006 Optical Society of America.

We found the experimental maximum Kerr rotation and ellipticity were about three times smaller than predicted and appeared at energies about 0.6 eV higher than predicted, which is possibly due to inaccurate handling of the theory based on the local spin-density approximation to density-function theory for the localized 4d and 5d orbitals in AuMnSn.

We report experimental observations of a large quantity of both stacking faults and twins in nc Ni deformed at relatively low stresses in a tensile test. The experimental findings indicate that the GPFE curves can reasonably explain the formation of stacking faults, but they alone were not able to adequately predict the propensity of deformation twinning.

With these combined techniques, we directly observe abrupt and flat transition from crystalline Si to hydrogenated amorphous Si at the interface of Si heterojunction solar cells. We find that high-quality hydrogenated amorphous Si layers can be grown abruptly by hot-wire chemical vapor deposition on 200 degrees C (100) Si substrates after a two-step pretreatment of the substrate, comprised of exposure to hot-wire decomposed H-2-diluted NH3 followed by atomic H etching.

The optical increase is similar, and our more limited radio data indicate a commensurate activity. We give the primary results of our Chandra X- Ray Observatory monitoring program and consider some of the implications of this extreme variability in a relativistic jet. We find that the data support a ''modest beaming synchrotron'' model as indicated in our earlier papers. Based on this model, the decay of the X- ray light curve appears to be dominated by the light-travel time across the emitting region of HST-1, rather than synchrotron loss timescales.

In addition to the two main subclusters and an infalling group detected in an earlier Chandra observation of the system, XMM- Newton detects another group of galaxies possibly associated with the cluster. This group may be connected to the northern subcluster by a filament of cool ( 1: 4 (+0.3)(-0.1) keV) X- ray-emitting gas and lies outside the estimated virial radius of the northern subcluster. The X- ray morphology agrees well with the projected galaxy distribution in new K-band imaging data presented herein. We use detailed spectral and imaging analysis of the X- ray data to probe the dynamics of the system and find evidence that another subcluster or group has recently passed through the northern subcluster. Cl J0152.7 - 1357 is an extremely dynamically active system, with mergers at different stages occurring along two perpendicular merger axes.

We fit a power-law function to the data using the revised trigger time given by Chincarini and coworkers, and a smoothly broken power-law to the data using the original trigger disseminated through the GCN notices. Including the RAPTOR data from Wozniak and coworkers, the best-fit power-law indices are alpha = -0.854 +/- 0.014 for the single power-law and alpha(1) = -0.364(-0.019)(+0.020), alpha(2) = -0.881(-0.031)(+0.030), with a break at t(b) = 418(-30)(+31) s for the smoothly broken fit. We discuss the fit results, with emphasis placed on the importance of knowing the true start time of the optical transient for this multipeaked burst. As Swift continues to provide prompt GRB locations, it becomes more important to answer the question, "when does the afterglow begin?'' in order to correctly interpret the light curves.

The alpha-form is consistent with the known structure type I of anhydrous lanthanide iodates. It consists of a three-dimensional network of pyramidal iodate groups bridging [AmO8] polyhedra where each of the americium ions are coordinated to eight iodate ligands. The beta-form reveals a novel architecture that is unknown within the f-element iodate series. beta-Am(IO3)(3) exhibits a two-dimensional layered structure with nine-coordinate Am-III atoms. Three crystallographically unique pyramidal iodate anions link the Am atoms into corrugated sheets that interact with one another through intermolecular IO3-...IO3- interactions forming dimeric I2O10 units. One of these anions utilizes all three O atoms to simultaneously bridge three Am atoms. The other two iodate ligands bridge only two Am atoms and have one terminal 0 atom. In contrast to alpha-Am(IO3)(3), where the [IO3] ligands are solely corner-sharing with [AmO8] polyhedra, a complex arrangement of corner- and edge-sharing mu(2)- and mu(3)-[IO3] pyramids can be found in beta-Am(IO3)(3).

It was observed that alcohol composition affects both the observed rate of hydrogen peroxide consumption (the limiting reagent) and the selectivity of hydrogen peroxide utilization to form cyclooctene epoxide. The catalytically active species are formed only in alcohol-containing solvents as a consequence of (F20TPP)FeCl dissociation into [(F20TPP)Fe(ROH)](+) cations and Cl- anions. The observed reaction kinetics are analyzed in terms of a proposed mechanism for the epoxidation of the olefin and the decomposition of H2O2. The first step in this scheme is the reversible coordination of H2O2 to [(F20TPP)Fe(ROH)](+). The O-O bond of the coordinated H2O2 then undergoes either homolytic or heterolytic cleavage. The rate of homolytic cleavage is found to be independent of alcohol composition, whereas the rate of heterolytic cleavage increases with alcohol acidity, Heterolytic cleavage is envisioned to form iron(IV) pi-radical cations, whereas homolytic cleavage forms iron(IV) hydroxo cations. The iron(IV) radical cations are active for olefin epoxidation, whereas the iron(IV) cations catalyze the decomposition of H2O2. Reaction of iron(IV) pi-radical cations with H2O2 to form iron(IV) hydroxo cations is also included in the mechanism, a process that is favored by alcohols with a high charge density on the 0 atoms. The proposed mechanism describes successfully the effects of H2O2, cyclooctene, and porphyrin concentrations, as well as the effects of alcohol concentration.

In our formulation, a coarse-scale continuum discretization is assumed to cover all parts of the computational domain with atomistic crystals introduced only in regions of interest. The geometry of the discretization and crystal are allowed to overlap arbitrarily. Our approach uses interpolation and projection operators to link the kinematics of each region, which are then used to formulate a system potential energy from which we derive coupled expressions for the forces acting in each region. A hyperelastic constitutive formulation is used to compute the stress response of the defect-free continuum with constitutive properties derived from the Cauchy-Born rule. A correction to the Cauchy-Born rule is introduced in the overlap region to minimize fictitious boundary effects. Features of our approach will be demonstrated with simulations in one, two and three dimensions. (c) 2005 Elsevier Inc. All rights reserved.

The algorithm is characterized by a pressure-correction method with the interfaces represented by volume fractions. Within this flow algorithm, we devise a continuous (e.g., continuum surface tension model) and a sharp (e.g., a ghost fluid method) interface representation of the surface-tension-induced interfacial pressure jump condition. The sharp interface representation is achieved by temporarily reconstructing distance functions from volume fractions. We demonstrate that a flow algorithm designed to legislate force balance retains an exact balance between surface tension forces and the resulting pressure gradients. This balance holds for both continuous and sharp representations of interfacial surface tension. The algorithm design eliminates one of the elusive impediments to more accurate models of surface tension-driven flow.. the remaining of which is accurate curvature estimation. To validate our formulation, we present results for an equilibrium (static) drop in two and three dimensions having an arbitrary density jump across the interface. We find that the sharp surface tension method yields an abrupt pressure jump across the interface, whereas the continuous surface tension method results in a smoother transition. Both methods, however, yield spurious velocities of the same order, the origin of which is due solely to errors in curvature. Dynamic results are also presented to illustrate the versatility of the method. (c) 2005 Elsevier Inc. All rights reserved.

The one-dimensional reactive Euler equations for a calorically perfect mixture of ideal oases whose reaction is described by single-step irreversible Arrhenius kinetics are solved in a series of calculations in which the activation energy is varied. In contrast with nearly all known simulations of this problem, which converge at a rate no greater than first order as the spatial and temporal grid is refined, the present method is shown to converge at a rate consistent with the fifth order accuracy of the spatial and temporal discretization schemes. This high accuracy enables more precise verification of known results and prediction of heretofore unknown phenomena. To five significant figures, the scheme faithfully recovers the stability boundary, growth rates, and wave-numbers predicted by an independent linear stability theory in the stable and weakly unstable regime. As the activation energy is increased. a series of period-doubling events are predicted, and the system undergoes a transition to chaos. Consistent with general theories of non-linear dynamics, the bifurcation points are seen to converge at a rate for which the Feigenbaum constant is 4.66 +/- 0.09, in close agreement with the true value of 4.669201.... As activation energy is increased further, domains are identified in which the system undergoes a transition from a chaotic state back to one whose limit cycles are characterized by a small number of non-linear oscillatory modes. This result is consistent with behavior of other non-linear dynamical systems, but not typically considered in detonation dynamics, The period and average detonation velocity are calculated for a variety of asymptotically stable limit cycles. The greater than the Chapman average velocity for such pulsating detonations is found to be slightly greater than the Chapman-Jouguet velocity. Published by Elsevier Inc.

Two possible realizations of a spin quantum computer (SQC) are analyzed: (i) a boundary spin chain in a 2D spin array and (ii) an isolated spin chain. In both cases, spin diffusion and relaxation are caused by a fast relaxing spin located outside the SQC. We have shown that in both cases the relaxation can be Suppressed by an external non-uniform magnetic field. In the second case, our computer simulations have revealed various types of relaxation processes including the excitation of a random distribution of magnetic moments and the formation of stationary and moving domain walls. The region of optimal parameters for suppression of rapid spin relaxation is discussed. (c) 2005 Elsevier B.V. All rights reserved. C1 Los Alamos Natl Lab, Div Theoret, Los Alamos, NM 87545 USA.

It is usually assumed that the dispersion is caused by a simultaneous injection of particles of all energies at some location, and by the subsequent drift of these particles to the synchronous altitude measurement site "downstream'' of the injection event. In this paper we present a method for timing and locating the injections from proton auroral precipitation inferred by the Lyman a emission data from the IMAGE FUV instrument. We compare the timing of the proton flux increases observed by the Los Alamos National Laboratory synchronous altitude satellites to the time delay predicted by a model describing the longitudinal drift of particles in the magnetosphere. We present comparisons for eleven substorm particle injections and find that the observed azimuthal drift times are reasonably consistent with those calculated by a simple model using the Tsyganenko 89 magnetic and Volland electric field models as input. This consistency supports the concept that the proton auroral intensification at substorm onset and the proton injection in the magnetosphere occur at the same magnetic local time (longitude).

In view of its central importance for biological and socioeconomic systems, model-simulated continental precipitation is evaluated relative to three observational estimates at both global and regional scales. Many models are found to display systematic biases, deviating markedly from the observed spatial variability and amplitude/phase of the seasonal cycle. However, the pointwise ensemble mean of all the models usually shows better statistical agreement with the observations than does any single model. Deficiencies of current models that may be responsible for the simulated precipitation biases as well as possible reasons for the improved estimate afforded by the multimodel ensemble mean are discussed. Implications of these results for water resource managers also are briefly addressed. C1 Lawrence Livermore Natl Lab, PCMDI, Livermore, CA 94551 USA.

Five TGF sferic waveforms detected at sufficiently close range were all found to be consistent with a positive-polarity intracloud (+ IC) discharge process which transported electrons upward. The amplitudes of the events were among the top 5% of IC discharge flashes. Altitudes obtained from ionosphere reflections for two of the closer events were found to be 13.6 km and 11.5 km. These altitudes are lower than expected if one assumes that the sferic was near the source of the gamma-rays. One of the sferics was an energetic narrow bipolar event which occurred near the inferred onset of a flash, suggesting that the preceding TGF may correspond to the actual onset.

CsoSCA lacks significant sequence similarity to any of the four known classes of carbonic anhydrase (alpha, beta, gamma, or delta), and so it was initially classified as belonging to a new class, epsilon. The crystal structure of CsoSCA from Halothiobacillus neapolitanus reveals that it is actually a representative member of a new subclass of beta-carbonic anhydrases, distinguished by a lack of active site pairing. Whereas a typical beta-carbonic anhydrase maintains a pair of active sites organized within a two-fold symmetric homodimer or pair of fused, homologous domains, the two domains in CsoSCA have diverged to the point that only one domain in the pair retains a viable active site. We suggest that this defunct and somewhat diminished domain has evolved a new function, specific to its carboxysomal environment. Despite the level of sequence divergence that separates CsoSCA from the other two subclasses of beta-carbonic anhydrases, there is a remarkable level of structural similarity among active site regions, which suggests a common catalytic mechanism for the interconversion of HCO(3)(-) and CO(2). Crystal packing analysis suggests that CsoSCA exists within the carboxysome shell either as a homodimer or as extended filaments.

Disks 1-2 mm thick were prepared by polymerization in a mold, disks thinner than I mm were prepared by impregnation of nylon or other porous filters prior to the polymerization step. These disks were evaluated for the preconcentration of iodine and selected organic solutes from dilute aqueous samples by solid-phase extraction (SPE). Quantitative measurement of the extracted solutes was achieved by diffuse-reflectance spectroscopy (DRS) directly on the surface of the disk. (c) 2005 Elsevier B.V. All rights reserved.

TonB-ExbB-ExbD transduces energy from the cytoplasmic membrane to the OM by contacts between TonB and OM receptors that contain the Ton box, a consensus sequence near the N terminus. Although the Ton box is a region of known contact between OM receptors and TonB, our biophysical studies established that TonB binds to FhuA through multiple regions of interaction. Panning of phage-displayed random peptide libraries (Ph.D.-12, Ph.D.-C7C) against TonB identified peptide sequences that specifically interact with TonB. Analyses of these sequences using the Receptor Ligand Contacts (RELIC) suite of programs revealed clusters of multiply aligned peptides that mapped to FhuA. These clusters localized to a continuous periplasm-accessible surface: Ton box/switch helix; cork domain/beta 1 strand; and periplasmic turn 8. Guided by such matches, synthetic oligonucleotides corresponding to DNA sequences identical to fhuA were fused to malE; peptides corresponding to the above regions were displayed at the N terminus of E. coli maltose-binding protein (MBP). Purified FhuA peptides fused to MBP bound specifically to TonB by ELISA. Furthermore, they competed with ligand-loaded FhuA for binding to TonB. RELIC also identified clusters of multiply aligned peptides corresponding to the Ton box regions in BtuB, FepA, and FecA; to periplasmic turn 8 in BtuB and FecA; and to periplasmic turns 1 and 2 in FepA. These experimental outcomes identify specific molecular contacts made between TonB and OM receptors that extend beyond the well-characterized Ton box. (c) 2005 Elsevier Ltd. All rights reserved.

We present a crystal structure of a fragment of c-AbI which reveals that a critical N-terminal cap segment, not visualized in previous structures, buttresses the SH3-SH2 substructure in the autoinhibited state and locks it onto the distal surface of the kinase domain. Surprisingly, the N-terminal cap is phosphorylated on a serine residue that interacts with the connector between the SH3 and SH2 domains. Small-angle X-ray scattering (SAXS) analysis shows that a mutated form of c-AbI, in which the N-terminal cap and two other key contacts in the autoinhibited state are deleted, exists in an extended array of the SH3, SH2, and kinase domains. This alternative conformation of AbI is likely to prolong the active state of the kinase by preventing it from returning to the autoinhibited state.

The general pathway for ubiquitin (Ub) modification requires the sequential activities of a Ub-activating enzyme (E1), a Ub transfer enzyme (E2), and a Ub ligase (E3). The E2 must recognize both the El and a cognate E3 in addition to carrying activated Ub. These central functions are performed by a topologically conserved alpha/beta-fold core domain of similar to 150 residues shared by all E2s. However, as presented herein, the UbcH5 family of E2s can also bind Ub noncovalently on a surface well removed from the E2 active site. We present the solution structure of the UbcH5c/ Ub noncovalent complex and demonstrate that this noncovalent interaction permits self-assembly of activated UbcH5c similar to Ub molecules. Self-assembly has profound consequences for the processive formation of polyubiquitin (poly-Ub) chains in ubiquitination reactions directed by the breast and ovarian cancer tumor susceptibility protein BRCA1.

We have determined a first experimental upper limit of 0.04 (90% C.L.) for the ratio parallel to g(E1)parallel to/parallel to g(M1)parallel to of the couplings for the E1 and M1 direct photon emission processes. We also report the measurement of parallel to g(M1)parallel to including a vector form factor parallel to g(M1)parallel to(1+a(1)/a(2)/(M-rho(2)-M-K(2))+2M(K)E(gamma+)), where parallel to g(M1)parallel to=1.11 +/- 0.12(stat)+/- 0.08(syst) and a(1)/a(2)=[-0.744 +/- 0.027(stat)+/- 0.032(syst)] GeV2/c(2). Finally, a CP-violating asymmetry of [13.6 +/- 1.4(stat)+/- 1.5(syst)]% in the CP and T odd angle phi between the decay planes of the e(+)e(-) and pi(+)pi(-) pairs in the K-L center of mass is reported.

Article ID HADRONIC TRANSITIONS; CDF-II; DETECTOR; X(3872); UPGRADE; STATES AB We measure the dipion mass spectrum in X(3872) -> J/psi pi(+)pi(-) decays using 360 pb(-1) of (p) over barp collisions at root s = 1.96 TeV collected with the CDF II detector. The spectrum is fit with predictions for odd C-parity (S-3(1), P-1(1), and D-3(J)) charmonia decaying to J/psi pi(+)pi(-), as well as even C-parity states in which the pions are from rho(0) decay. The latter case also encompasses exotic interpretations, such as a D-0(D) over bar*(0) molecule. Only the S-3(1) and J/psi rho hypotheses are compatible with our data. Since S-3(1) is untenable on other grounds, decay via J/psi rho is favored, which implies C = +1 for the X(3872). Models for different J/psi-rho angular momenta L are considered. Flexibility in the models, especially the introduction of rho-omega interference, enables good descriptions of our data for both L = 0 and 1. C1 Acad Sinica, Inst Phys, Taipei 11529, Taiwan.

Such holes could be created as a result of nucleon decay into invisible modes (inv), e.g., n -> 3 nu or nn -> 2 nu. The deexcitation of the corresponding daughter nucleus results in a sequence of space and time-correlated events observable in the liquid scintillator detector. We report on new limits for one- and two-neutron disappearance: tau(n -> inv)> 5.8x10(29) years and tau(nn -> inv)> 1.4x10(30) years at 90% C.L. These results represent an improvement of factors of similar to 3 and > 10(4) over previous experiments. C1 Tohoku Univ, Res Ctr Neutrino Sci, Sendai, Miyagi 9808578, Japan.

At the bulk structural phase transition temperature of 48 K, we find clear evidence for an electronic instability, gapping large parts of the underlying Fermi surface that appears to be nested. Metallic pockets are found to survive in the small, non-nested sections, constituting a low-temperature Fermi surface with 2 orders of magnitude smaller volume than in all other metallic ruthenates. The Fermi velocities and volumes of these pockets are in agreement with the results of complementary quantum oscillation measurements on the same crystal batches.

Physical and mechanical properties were measured after deformation, and a systematic strain-induced softening was observed which contrasts sharply with the hardening typically observed in crystalline metals. If the deformed glass is treated as a composite of hard amorphous grains surrounded by soft shear-band boundaries, analogous to nanocrystalline materials that exhibit inverse Hall-Petch behavior, the correct functional form for the dependence of hardness on shear-band spacing is obtained. Deformation-induced softening leads naturally to shear localization and brittle fracture. C1 Univ Tennessee, Dept Mat Sci & Engn, Knoxville, TN 37996 USA.

Although it is tempting to attribute a nondispersive behavior in momentum space to charge ordering, a deconstruction of the autocorrelation reveals that the nondispersive peaks arise from the tips of the Fermi arcs, which themselves do not change with binding energy.

It is found that quantum size effects lead to the breakdown of the classical Gibbs-Thomson analysis. This is manifested by the lack of scaling of the island densities. In addition, island decay times tau are orders of magnitude faster than expected from the classical analysis and have an unusual dependence on the growth flux F (i.e., tau similar to 1/F). As a result, a highly monodispersed 7-layer island height distribution is found after coarsening if the islands are grown at high rather than low flux rates. These results have important implications, especially at low temperatures, for the controlled growth and self-organization of nanostructures.

The unprecedented effectiveness in avoiding the effect of external strain, or any other effects originating from the surrounding environment, lead to an accurate measurement of the band gap temperature dependence, giving fundamental insight into the nanotube electron-phonon interaction. Small but reproducible energy shifts of the emission lines with temperature were observed, showing a moderate chirality dependence, well in agreement with recent theoretical calculations. In addition to the energy shift, a substantial narrowing of the emission lines was also observed. The removal of the temperature shift of the band gap allows the precise measurement of the effect of external strain on carbon nanotubes in different environments.

We show that the charge transfer is governed by the coherent two-electron-Cooper pair conversion process time-reversal reflection, where electrons tunnel into a superconductor from the localized states in the hopping insulator located near the interface, and calculate the corresponding interface resistance. A specific feature of this problem is the interplay between the time-reversal reflection at the interface and transport through the percolation cluster. To allow for this interplay, we have generalized the connectivity criterion of the percolation theory to include surface effects. We show that the time-reversal interface resistance is accessible experimentally, and that in mesoscopic structures it can exceed the bulk hopping resistance.

At the shortest scales, the poloidal wavelengths are comparable to the scale length of electrostatic drift wave turbulence.

A single Ca vacancy V-Ca(0) has a magnetic moment due to its open-shell structure but the ferromagnetic interaction between two vacancies extends only to four neighbors or less. To achieve magnetic percolation on a fcc lattice with such an interaction range one needs a minimum of 4.9% vacancies, or a concentration 1.8x10(21) cm(-3). Total-energy calculations for CaO show, however, that due to the high vacancy formation energy even under the most favorable growth conditions one can not obtain more than 0.003% or 10(18) cm(-3) vacancies at equilibrium, showing that a nonequilibrium vacancy-enhancement factor of 10(3) is needed to achieve magnetism in such systems.

The measured frequency dependent magnetic and electric resonances are in excellent agreement with theory and simulation. For two polarizations, the SRRs yield a negative electric response (epsilon < 0). We demonstrate, for the first time, dynamical control of the electrical response of the SRRs through photoexcitation of free carriers in the substrate. An excited carrier density of similar to 4x10(16) cm(-3) is sufficient to short the gap of the SRRs, thereby turning off the electric resonance, demonstrating the potential of such structures as terahertz switches. Because of the universality of metamaterial response over many decades of frequency, these results have implications for other regions of the electromagnetic spectrum.

The strategy exploits annotation data present in gene-centered corpora and utilizes ideas from statistical information retrieval to discover and characterize properties shared by subsets of the list. The practical utility of this method is demonstrated by employing it in a retrospective study of two non-overlapping sets of genes defined by a published investigation as markers for normal human breast luminal epithelial cells and myoepithelial cells. Results: Each genetic locus was characterized using a finite set of biological properties and represented as a vector of features indicating attributes associated with the locus ( a gene attribute profile). In this study, the vector space models for a pre-defined list of genes were constructed from the Gene Ontology ( GO) terms and the Conserved Domain Database (CDD) protein domain terms assigned to the loci by the gene-centered corpus LocusLink. This data set of GO- and CDD-based gene attribute profiles, vectors of binary random variables, was used to estimate multiple finite mixture models and each ensuing model utilized to partition the profiles into clusters. The resultant partitionings were combined using a unanimous voting scheme to produce consensus clusters, sets of profiles that co-occured consistently in the same cluster. Attributes that were important in defining the genes assigned to a consensus cluster were identified. The clusters and their attributes were inspected to ascertain the GO and CDD terms most associated with subsets of genes and in conjunction with external knowledge such as chromosomal location, used to gain functional insights into human breast biology. The 52 luminal epithelial cell markers and 89 myoepithelial cell markers are disjoint sets of genes. Ensemble attribute profile clustering-based analysis indicated that both lists contained groups of genes with the functional properties of membrane receptor biology/signal transduction and nucleic acid binding/transcription. A subset of the luminal markers was associated with metabolic and oxidoreductase activities, whereas a subset of myoepithelial markers was associated with protein hydrolase activity. Conclusion: Given a set of genes and/or proteins associated with a phenomenon, process or system of interest, ensemble attribute profile clustering provides a simple method for collating and sythesizing the annotation data pertaining to them that are present in text-based, gene-centered corpora. The results provide information about properties common and unique to subsets of the list and hence insights into the biology of the problem under investigation.

The high-accuracy retrieval goals of AIRS (e.g., 1 K RMS in 1 km layers below 100 mbar for air temperature, 10% RMS in 2 km layers below 100 mbar for water vapor concentration), combined with the large temporal and spatial variability of the atmosphere and difficulties in making accurate measurements of the atmospheric state, necessitate careful and detailed validation using well-characterized ground-based sites. As part of ongoing AIRS Science Team efforts and a collaborative effort between the NASA Earth Observing System (EOS) project and the Department of Energy Atmospheric Radiation Measurement (ARM) program, data from various ARM and other observations are used to create best estimates of the atmospheric state at the Aqua overpass times. The resulting validation data set is an ensemble of temperature and water vapor profiles created from radiosondes launched at the approximate Aqua overpass times, interpolated to the exact overpass time using time continuous ground-based profiles, adjusted to account for spatial gradients within the Advanced Microwave Sounding Unit (AMSU) footprints, and supplemented with limited cloud observations. Estimates of the spectral surface infrared emissivity and local skin temperatures are also constructed. Relying on the developed ARM infrastructure and previous and ongoing characterization studies of the ARM measurements, the data set provides a good combination of statistics and accuracy which is essential for assessment of the advanced sounder products. Combined with the collocated AIRS observations, the products are being used to study observed minus calculated AIRS spectra, aimed at evaluation of the AIRS forward radiative transfer model, AIRS observed radiances, and temperature and water vapor profile retrievals. This paper provides an introduction to the ARM site best estimate validation products and characterizes the accuracy of the AIRS team version 4 atmospheric temperature and water vapor retrievals using the ARM products. The AIRS retrievals over tropical ocean are found to have very good accuracy for both temperature and water vapor, with RMS errors approaching the theoretical expectation for clear sky conditions, while retrievals over a midlatitude land site have poorer performance. The results demonstrate the importance of using specialized "truth'' sites for accurate assessment of the advanced sounder performance and motivate the continued refinement of the AIRS science team retrieval algorithm, particularly for retrievals over land.

The gas-phase reactivity of the met-car with SCO, CS2, and SO2 was investigated in a hexapole collision cell by way of tandem mass spectrometry. Results indicate an increase in activity as the oxygen-to-sulfur ratio increases (SO2 > SCO > CS2) with products ranging from association to break down of the met-car cluster. Trends in the mass spectra also indicate SCO and CS2 may bond to the met-car in a unique way not observed in previous reactivity studies on Ti8C12+. To investigate this, several possible single molecule-cluster bonding configurations were calculated with density functional theory. The results indicate that bridge bonding of the intact molecules is energetically preferred. In addition, the energy barriers and transition states leading to dissociation products were calculated and the trends are found to be in qualitative agreement with experiment. The effects of the different types of bonding and number of adsorbed species on the reactivity of the met-car along with proposed reaction mechanisms for product formation are also discussed.

Three electronic bands are observed and assigned to the X-2 Sigma(+)(u) <- X-1 Sigma(+)(g), A(2)Pi(u) <- X-1 Sigma(+)(g), and B-2 Sigma(+)(g) <- X-1 Sigma(+)(9) electronic transitions, with the caveat that one or both excited states may be slightly bent. With the aid of density functional theory calculations and Franck-Condon spectral simulations, we determine the adiabatic electron affinity of Al2N, 2.571 +/- 0.008 eV, along with geometry changes upon photodetachment, vibrational frequencies, and excited-state term energies. Observation of excitation of the odd vibrational levels of the antisymmetric stretch (v(3)) suggests a breakdown of the Franck-Condon approximation, caused by the vibronic coupling between the X2Xu+ and B-2 Sigma(+)(g) electronic states through the v(3) mode.

Isomers of C4H3 and C4H5 in flames fueled by allene, propyne, cyclopentene, or benzene are identified by comparison of the observed photoionization efficiencies with theoretical simulations based on calculated ionization energies and Franck-Condon factors. The experiments combine molecular-beam mass spectrometry (MBMS) with photoionization by tunable vacuum-ultraviolet synchrotron radiation. The theoretical simulations employ the rovibrational properties obtained with B3LYP/6-311++G(d,p) density functional theory and electronic energies obtained from QCISD(T) ab initio calculations extrapolated to the complete basis set limit. For C4H3, the comparisons reveal the presence of the resonantly stabilized CH2CCCH isomer (i-C4H3). For C4H5, contributions from the CH2CHCCH2 (i-C4H5) and some combination of the CH3CCCH2 and CH3-CHCCH isomers are evident. Quantitative concentration estimates for these species are made for allene, cyclopentene, and benzene flames. Because of low Franck-Condon factors, sensitivity to n-isomers of both C4H3 and C4H5 is limited. Adiabatic ionization energies, as obtained from fits of the theoretical predictions to the experimental photoionization efficiency curves, are within the error bars of the QCISD(T) calculations. For i-C4H3 and i-C4H5, these fitted adiabatic ionization energies are (8.06 +/- 0.05) eV and (7.60 +/- 0.05) eV, respectively. The good agreement between the fitted and theoretical ionization thresholds suggests that the corresponding theoretically predicted radical heats of formation (119.1, 76.3, 78.7, and 79.1 kcal/mol at 0 K for i-C4H3, i-C4H5, CH3CCCH2, and CH3CHCCH, respectively) are also quite accurate.

At all tern reaction proceeds through the 4e(-) reaction pathway with a very small (approximate to 0.5-2%) peroxide formation. At the same temperature and overpotentials, the kinetics of the ORR always increases in the order (100) <= (111) < (110), indicating that the reaction is structure-sensitive. We present an interpretation of the structure sensitivity based on the supposition that it arises from (i) a potential-dependent adsorption of spectator hydroxyl ions and (ii) variations in activation energies, which are determined by the O-2 adsorption on Ag single-crystal surfaces covered by adsorbed oxygenated species.

It has been found that TEDA binds more strongly to both Lewis acid sites and to Bronsted Al-OH sites than does CO. Competition experiments indicate that TEDA displaces CO to less strong binding sites. Evidence for weak CO center dot center dot center dot TEDA interactions is found in which small v(CO) redshifts are produced. Comparison between different amines such as triethylenemonoamine (TEMA) (also called 1-azabicyclo[2.2.2]octane, ABCO), trimethylamine (TMA), and ammonia indicates that the v(CO) redshift increases with increasing amine polarizability, indicating that the redshift is mainly due to dipole image damping effects on the CO oscillator frequency. The direct bonding between the exposed N lone pair electrons of the TEDA molecule and CO does not occur. First principles theoretical studies have characterized the bonding of CO with gamma-Al2O3 Lewis acid sites of various types as well as TEDA bonding to both Lewis acid sites and to Al-OH groups. The theoretical studies also indicate that strong bonding of adsorbed CO with TEDA molecules does not occur, and that the observed decrease in the binding energy of CO when coadsorbed with TEDA on gamma-Al2O3 is expected.

These silicon nanostructures were shaped by a high-temperature acetylene and ammonia dc plasma reactive ion etch (RIE) process. Thin-film copper deposited onto Si substrates forms a copper silicide (Cu3Si) during plasma processing, which subsequently acts as a seed material masking the single-crystal cones while the exposed silicon areas are reactive ion etched. In this process, the cone angle is sharpened continually as the structure becomes taller. Furthermore, by lithographically defining the seed material as well as employing an etch barrier material such as titanium, the cone location and substrate topography can be controlled effectively.

While the spatial model accounted for intra- and inter-county epidemic spread, the non-spatial model did not assess regional differences. A geocoded dataset that resembled conditions favouring homogeneous mixing assumptions (based on the 2001 Uruguayan foot-and-mouth disease epidemic), was used for testing. Significant differences between models were observed in the average transmission rate between farms, both before and after a control policy (animal movement ban) was imposed. They also differed in terms of daily number of infected farms: the non-spatial model revealed a single epidemic peak (at, approximately, 25 epidemic days); while the spatial model revealed two epidemic peaks (at, approximately, 12 and 28 days, respectively). While the spatial model fitted well with the observed cumulative number of infected farms, the non-spatial model did not (P < 0.01). In addition, the spatial model: (a) indicated an early intra-county reproductive number R of similar to 87 (falling to < 1 within 25 days), and an inter-county R < 1; (b) predicted that, if animal movement restrictions had begun 3 days before/after the estimated initiation of such policy, cases would have decreased/increased by 23 or 26%, respectively. Spatial factors (such as inter-farm distance and coverage of vaccination campaigns, absent in nonspatial models) may explain why partially explicit spatial models describe epidemic spread more accurately than non-spatial models even at early epidemic phases. Integration of geo-coded data into mathematical models is recommended. (c) 2005 Elsevier B.V. All rights reserved. C1 Cornell Univ, Dept Biol Stat & Computat Biol, Ithaca, NY 14853 USA.

The method turns on repositioning the data from the prismatic array to the Latin square array. A polynomial interpolating equation is applied to the latter design to estimate surrogate numbers for data not originally present in the prismatic array. The five data and four surrogate numbers are then repositioned in the original nine-point cube. The cube is represented by another polynomial in order to estimate the three curvature coefficients. The method is capable of yielding estimates that are within an order of magnitude of the true values. (c) 2005 Elsevier Inc. All rights reserved. C1 Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

An unknown number of these genes also possess multiple transcriational promoters and alternative first exons that contribute another layer of complexity to gene expression mechanisms. Using a collection of more than 100 erythroid-expressed genes as a test group, we used genome browser tools and genetic databases to assess the frequency of alternative first exons in the genome. Remarkably, 35% of these erythroid genes show evidence of alternative first exons. The majority of the candidate first exons are situated upstream of the coding exons, whereas a few are located internally within the gene. Computational analyses predict transcriptional promoters closely associated with many of the candidate first exons, supporting their authenticity. Importantly, the frequent presence of consensus translation initiation sites among the alternative first exons suggests that many proteins have alternative N-terminal structures whose expression can be coupled to promoter choice. These findings indicate that alternative promoters and first exons are more widespread in the human genome than previously appreciated and that they may play a major role in regulating expression of selected protein isoforms in a tissue-specific manner.

Widely used conversion coating treatment formulations contain hexafluorozirconate as a major constituent besides chromate, ferricyanide, fluoride, and fluoborate. The function of hexafluorozirconate is the subject of this study as its function is still largely unknown. Hydrophobicity, surface morphology, and the chemistry of the surface, resulting from treatment with hexafluorozirconate, were studied using contact angle measurements, scanning electron microscopy, and energy dispersive spectroscopy, respectively. X-ray photoelectron spectroscopy was extensively utilized to determine the chemistry of the surface resulting from the hexafluorozirconate pretreatment. Our results indicate that fluoride ion containing hexafluorozirconate complex does not attack the oxide film in a manner that uncomplexed simple fluoride ion does. Hexafluorozirconate is involved in the formation of an Al-Zr-O-F based hydrated layer that increases the hydrophilicity of the surface, activates the surface, and lowers the corrosion resistance. These factors enhance the interaction of chromate with the alloy surface to result in the formation of a uniform conversion coating. Based on these results, a new model has been proposed for the formation of chromate conversion coatings. (c) 2005 Elsevier Ltd. All rights reserved.

However, surface chemical interactions of nicotine have not been sufficiently characterized. Here, the reaction of ozone with nicotine sorbed to Teflon and cotton surfaces was investigated in an environmental chamber by monitoring nicotine desorption over a week following equilibration in dry or humid air (similar to 0% or 65-70% RH, respectively). The Teflon and cotton surfaces had N-2-BET surface areas of 0.19 and 1.17 m(2) g(-1), and water mass uptakes (at 70% RH) of 0 and 7.1% respectively. Compared with dry air baseline levels in the absence Of O-3, gas-phase nicotine concentrations decreased by 2 orders of magnitude for Teflon after 50 h at 20-45 ppb O-3, and by a factor of 10 for cotton after 100 h with 13-15 ppb O-3. The ratios of pseudo first-order rate constants for surface reaction (r) to long-term desorption W were r/k = 3.5 and 2.0 for Teflon and cotton surfaces, respectively. These results show that surface oxidation was competitive with desorption. Hence, oxidative losses could significantly reduce long-term re-emissions of nicotine from indoor surfaces. Formaldehyde, N-methylformamide, nicotinaldehyde, and cotinine were identified as oxidation products, indicating that the pyrrolidinic N was the site of electrophilic attack by O-3. The presence of water vapor had no effect on the nicotine-O-3 reaction on Teflon surfaces. By contrast, nicotine desorption from cotton in humid air was unaffected by the presence of ozone. These observations are consistent with complete inhibition of ozone-nicotine surface reactions in an aqueous surface film present in cotton but not in Teflon surfaces.

With respect to Fe(III) (hydr)oxides bearing sorbed divalent metals, recent reports have indicated that (1) microbial reduction of goethite/ferrihydrite mixtures preferentially removes ferrihydrite, (2) this process can incorporate previously sorbed Zn(II) into an authigenic crystalline phase that is insoluble in 0.5 M HCl, (3) this new phase is probably goethite, and (4) the presence of nonreducible minerals can inhibit this transformation. This study demonstrates that a range of sorbed transition metals can be selectively sequestered into a 0.5 M HCl insoluble phase and that the process can be stimulated through sequential steps of microbial iron reduction and air oxidation. Microbial reduction experiments with divalent Cd, Co, Mn, Ni, Pb, and Zn indicate that all metals save Mn experienced some sequestration, with the degree of metal incorporation into the 0.5 M HCl insoluble phase correlating positively with crystalline ionic radius at coordination number = 6. Redox cycling experiments with Zn adsorbed to synthetic goethite/ferrihydrite or iron-bearing natural sediments indicate that redox cycling from iron reducing to iron oxidizing conditions sequesters more Zn within authigenic minerals than microbial iron reduction alone. In addition, the process is more effective in goethite/ferrihydrite mixtures than in iron-bearing natural sediments. Microbial reduction alone resulted in a similar to 3x increase in 0.5 M HCl insoluble Zn and increased aqueous Zn (Zn-aq) in goethite/ferrihydrite, but did not significantly affect Zn speciation in natural sediments. Redox cycling enhanced the Zn sequestration by similar to 12% in both goethite/ferrihydrite and natural sediments and reduced Zn-aq to levels equal to the uninoculated control in goethite/ferrihydrite and less than the uninoculated control in natural sediments. These data suggest that in situ redox cycling may serve as an effective method for mitigating divalent metal contamination in subsurface environments.

It is already well established in materials science, and it is becoming a significant tool for the electrochemical community. As with all X-ray absorption spectroscopies, extended X-ray absorption fine structure (EXAFS) has the advantage of being element specific. Interpretation of the spectra at different states of charge can provide very useful quantitative and qualitative information about the valence change of the constituent elements in the cathode material during the ongoing electrochemical reaction, the degree of distortion or changes in structure from the initial state of charge to the final state of charge and provide valuable information about the extent of degradation of the cathode material during continuous cycling. It can also provide valuable insight about how the nature of the electrochemical reactions changes when one of the transition metal constituents is removed or increased in content in the cathode material. It is often important to adjust the composition of the cathode material in order to achieve high specific capacity and long-term stability in Li-ion cells. This article details the development of the in situ XAS techniques to study electrochemical reactions using various X-ray absorption spectroscopies which are now possible with the advent of third generation synchrotron radiation sources and improved end stations. The strength of in situ EXAFS techniques is illustrated using examples of various interesting transition metal oxides. In this way, we aim to encourage chemists, chemical engineers and materials scientists to consider in situ X-ray absorption spectroscopy as an effective tool for developing an understanding the electronic structure of materials and the changes that it undergoes during electrochemical reactions.

The method is applicable to problems involving advective, dispersive, and diffusive transport in a porous medium. By representing the continuously variable solid solution composition with a discrete set of stoichiometric solids that span composition space, combined with a kinetic formulation of their rates of reaction, a self-determining spatial and temporal evolution of the solid solution concentration and composition is obtained. It is demonstrated that equilibrium of an aqueous solution with a stoichiometric solid derived from a solid Solution corresponds to equilibrium of the solid solution itself if and only if equilibrium of the stoichiometric solid is stable. One advantage of this approach is that it is unnecessary to introduce any additional compositional variables to represent the solid solution. Discretization may be over the entire range of composition space, or over some subset depending on the system. A major consequence of the kinetic discrete-composition solid solution representation is that modeling solid solutions is similar to modeling pure mineral phases with the exception of a weighting factor applied to reaction rates of stoichiometric solids corresponding to a common solid solution. With this approach, precipitation leads to a discrete zonation of the solid solution that approximates the continuous variation in composition expected for the actual solid solution. The approach is demonstrated for a hypothetical ideal and non-ideal binary solid solution A(x)B(1-x)C for a reaction path formulation and reactive transport involving advection and diffusion.

However, to our knowledge, there have been no direct studies of the effects of these species on U(VI) adsorption by mineral phases. The sorption of U(VI) oil quartz and ferrihydrite was investigated in NaNO3 solutions equilibrated with either ambient air (430 ppm CO2) or 2% CO2 in the presence of 0, 1.8, or 8.9 mM Ca2+. Under conditions where the Ca2UO2(CO3)(3)(0)(aq) species predominates U(VI) aqueous speciation, the presence of Ca in solution lowered U(VI) adsorption on quartz from 77% in the absence of Ca to 42% and 10% at Ca concentrations of 1.8 and 8.9 mM, respectively. U(VI) adsorption to ferrihydrite decreased from 83% in the absence of Ca to 57% in the presence of' 1.8 mM Ca. Surface complexation model predictions that included the formation constant for aqueous Ca2UO2(CO3)(3)(0)(aq) accurately simulated the effect of Ca2+ on U(VI) sorption onto quartz and ferrihydrite within the thermodynamic uncertainty of the stability constant value. This study confirms that Ca2+ call have a significant impact on the aqueous speciation of U(VI), and consequently, oil the sorption and mobility of U(VI) in aquifers. (c) 2006 Elsevier Inc.

Such a result suggests the existence of an atmospheric halo made up of molecular oxygen surrounding the rings. It is produced by solar UV radiation-induced decomposition of ice releasing molecular oxygen which does not stick on the surface at the relevant temperatures. A Monte Carlo model of the atmosphere/ionosphere ring system that uses test-particles and incorporates chemical processes and transport of both neutrals and plasma ions is developed. Published ion data from the ion mass spectrometer (IMS) experiment were used as constraint and the model provides a very satisfactory fit between simulated O+ and O-2(+) ion densities and those measured along Cassini trajectory.

This study focuses on how anomalous atmospheric circulation affects snowpack accumulation in the western USA. Our results indicate that the mid-latitude atmospheric circulation anomalies induced by the El Ni (n) over tildeo-Southern Oscillation (ENSO) tend to drive winter precipitation shifts, leading to an anomalous snowpack distribution in the western USA. The warm phase of ENSO produces increased snowpack in the Southwest, whereas the cold phase generates increased snowpack in the Northwest. The results also indicate that temperature has a secondary impact on the anomalous snowpack distribution during ENSO episodes. Additionally, the atmospheric internal variability-related Pacific-North American (PNA) pattern is found to affect snow anomalies strongly in the western USA independent from ENSO. The positive phase of the PNA pattern produces colder temperature and stronger precipitation due to the lower pressure in the region, leading to an above-average snowpack. Conversely, the negative phase of the PNA pattern generates warmer temperature and weaker precipitation resulting from the higher pressure, producing below-average snowpack in the western USA. The significant findings that result from this study strengthen our understanding of climate and water supply variability in the western USA. Copyright (c) 2006 John Wiley & Sons, Ltd.

A study of the structural perturbation, charge compensation mechanism, and the valence of the constituent transition metal elements (Ni and Mn) during electrochemical cycling was performed using x-ray absorption spectroscopy (XAS) employing an in situ technique with an electrochemical cell designed for long term x-ray experiments. We present the changes in the oxidation state, bond distance, and coordination number of the Ni and Mn absorbers as a function of the state of charge of the material during electrochemical cycling at moderate rate through a typical Li-ion battery operating voltage range (2.9-4.7 V). The oxidation states of the transition metals in LiNi0.5Mn0.5O2 are Mn4+ and Ni2+. The x-ray absorption near edge spectra reveal that on delithiation of Li1-xNi0.5Mn0.5O2 the Mn is electrochemically inactive and remains at Mn4+ whereas the Ni is oxidized from Ni2+ to almost Ni4+ through an intermediate stage of Ni3+. A quantitative picture of the Ni valence during the charging process was obtained employing Faraday's law calculations in combination with the XAS results. The Faraday's law calculation indicated that at the end of the charge Ni is at Ni3.91+ in close agreement with the XAS results where Ni is found to be at Ni3.88+ at the end of the charge. Analysis of the extended x-ray absorption fine structure shows that during cycling the material retains its crystallographic symmetry and good structural short-range order which should lead to stable cycling.

We have observed the continuous evolution of the magnetic domain states in the square ferromagnetic elements on top of the plateaus as a function of film thickness. At high film thickness we observe the Landau state, which is the expected lowest energy state, but at lower thickness we see a variety of metastable states which are trapped as a result of local pinning. In a small thickness range below 10 nm, the square elements contain 360 degrees walls and small domains which are likely to be a result of local effects such as magnetocrystalline anisotropy and edge roughness. We are able to simultaneously observe the development of the magnetic domains in the continuous polycrystalline film surrounding the plateaus and, rather than the expected large domains, we observe at intermediate film thickness a significant modification of the domain configuration to small domains. Here the roughness of the silicon substrate surrounding the plateaus, which is due to the reactive ion etching process used to prepare the prepatterned substrates, gives rise to local stray fields in the ferromagnetic film which play an important role in determining the resulting domain structure.

The energy band gap of Zn1-xCdxO films decreases with increasing Cd content. An increase of Cd content also leads to the emission broadening, absorption edge broadening, and crystallinity degradation. The absorption edge and ultraviolet emission energy shift to lower energy from 3.357 eV to 3.295 eV and 3.338 eV to 3.157 eV, respectively, with increasing Cd content from 0.3% to 3% at 4 K. The Stokes' shift between the absorption and emission is observed and that indicates the increase of exciton localization with Cd content. (c) 2006 American Institute of Physics.

Appl. Phys. 82, 6319 (1997)]. Carrier trapping directly affects the density and mobility balance between electrons and holes through its effects on injection and mobility. In addition, trap-mediated changes in density alter recombination rates and spatial profiles of recombination that become important when excited state quenching at metallic contacts is considered. We illustrate these various influences of traps on device efficiency through computations on a series of model devices. Good agreement is obtained with previous experiments by Menon [Chem. Mater. 14, 3668 (2002)], where energetic disorder from transport traps was shown to reduce device efficiency. Our model, however, predicts circumstances where traps will improve device efficiency as well and can assist with selection of contacts to realistic organic materials.

In this paper we present macroscopic measurements obtained from a single crystal of Ni50Mn28.7Ga21.3 which demonstrate a large reversible MFIS of -4100 ppm when the alloy is driven with quasistatic magnetic fields and fixed compressive stresses applied collinearly along the [001] axis. This collinear configuration marks a fundamental difference with prior research in the field and points to the existence in this alloy of stable bias or residual stresses-likely associated with pinning sites in the alloy-which provide the energy necessary to restore the original variant state when the field is reversed. We present macroscopic magnetomechanical measurements which show a decrease of the MFIS with increasing stress loading and a stiffening of the alloy with increasing dc fields. The latter behavior is phenomenologically similar to the Delta E effect in magnetostrictive materials. The large reversible MFIS and tunable stiffness properties exhibited by this alloy could enable practical Ni-Mn-Ga actuators for high-deflection, low-force applications which due to being driven by a solenoid transducer are more compact, energy efficient, and faster than their electromagnet counterpart. A thermodynamic model is presented which qualitatively characterizes the decay in MFIS with increasing compressive external load and provides a starting point for the characterization, design, and control of the proposed Ni-Mn-Ga devices.

This isotopically enriched diamond tip was then used in conjunction with a natural isotopic abundance diamond anvil to generate high pressure on the sample. We provide a calibration for the C-13 Raman mode of this extremely thin epitaxial layer to 156 GPa using ruby fluorescence and the equation of state of copper as secondary pressure standards. The nonlinear calibration of the C-13 Raman mode pressure sensor is compared with similar calibrations of C-12 Raman edge and a good agreement is obtained. The Raman signal from the C-13 epitaxial layer remained a distinct singlet to 156 GPa, and pressure calibration is independent of sample mechanical strength or the diamond anvil geometry. The use of even thinner layer would allow calibration further into ultrahigh pressure regime where the use of other optical sensors has proven to be difficult. (c) 2006 American Institute of Physics.

Irradiated specimens were examined using grazing incidence x-ray diffraction and transmission electron microscopy. Ion irradiation leads to different radiation effects in these three materials. First, Dy2O3 begins to transform to a monoclinic B-type rare earth structure (C2/m) at a peak dose of similar to 5 displacements per atom (dpa), (corresponding to a fluence of 2x10(19) Kr/m(2)). This transformation is nearly complete at a peak dose of 25 dpa (a fluence of 1x10(20) Kr/m(2)). Er2O3 also transforms to the B-type structure, but the transformation starts at a higher irradiation dose of about 15-20 dpa [a fluence of about (6-8)x10(19) Kr/m(2)]. Lu2O3 was found to maintain the C-type structure even at the highest irradiation dose of 25 dpa (a fluence of 1x10(20) Kr/m(2)). No C-to-B transformation was observed in Lu2O3. The irradiation dose dependence of the C-to-B phase transformation observed in Dy2O3, Er2O3, and Lu2O3 is closely related to the temperature dependence of the C-to-B phase transformation found in phase diagrams for these three materials.

Hydroxyethyl methacrylate (HEMA)-based hydrogels have been developed for the controlled release of CPC. Initial burst release of the biocide can be controlled and sustained release can be achieved for more than two weeks. The burst and sustained release can be adjusted by varying the amount of anionic monomer (AMPSA), crosslink content (DEGDMA), release media, hydrogel surface area, and CPC loading. After removing the CPC-loaded hydrogel from solution and drying, the release of CPC can also be reactivated. Very interesting swelling behavior was observed for CPC-loaded hydrogels due to the electrostatic and hydrophobic interactions between the polymer hydrogel and CPC. In addition, HEMA-based hydrogels can be used to recover or absorb CPC from aqueous solutions. By increasing the amount of AMPSA in the HEMA-based hydrogel, more CPC can be absorbed from solution. The absorption is also enhanced by agitating the solution. (c) 2005 Wiley Periodicals, Inc. C1 Los Alamos Natl Lab, Div Chem, Chem Sci & Engn Grp, Los Alamos, NM 87545 USA.

The bottles were manufactured using a two-stage injection stretch blow molding process. Splitting of PET bottle bases under load is both inconvenient and expensive. In this study, SAXS data were collected with a 100 mu m square X-ray beam to establish the molecular morphology as a function of position across the base topology. An amorphous region was identified in the base center (i.e., close to the injection gate of the preform) with biaxially orientated, semicrystalline regions in the feet and valleys of the bottle bases. For bottles that had split under load, the transition between these two regions displayed uniaxial orientation that would lead to reduced mechanical strength in the circumferential direction. Reasons for this effect are explored. (c) 2006 Wiley Periodicals, Inc. C1 Australian Nucl Sci & Technol Org, Menai, NSW 2234, Australia. CRC Polymers, Notting Hill, Vic 3168, Australia.

The primary goal here is to assess the range of regional climate responses to increased greenhouse gases in available RCM simulations. The four RCMs used different geographical domains, different increased greenhouse gas scenarios for future-climate Simulations, and (in some cases) different lateral boundary conditions. For simulations of the present climate, RCM results are compared to observations and to results of the GCM that provided lateral boundary conditions to the RCM. For future-climate (increased greenhouse gas) simulations, RCM results are compared to each other and to results of the driving GCMs. When results are spatially averaged over the western United States, it is found that the results of each RCM closely follow those of the driving GCM in the same region in both present and future climates. This is true even though the study area is in some cases a small fraction of the RCM domain. Precipitation responses predicted by the RCMs in many regions are not statistically significant compared to interannual variability. Where the predicted precipitation responses are statistically significant, they are positive. The models agree that near-surface temperatures will increase, but do not agree on the spatial pattern of this increase. The four RCMs produce very different estimates of water content of snow in the present climate, and of the change in this water content in response to increased greenhouse gases.

We observe the solidification front in real time by optical microscopy. We use micromanipulation with a holographic laser spot array for perturbing the solidification front on a scale ranging from one to ten times the average lamellar spacing value (typically 10-100 mu m). These perturbations arise from local heating due to the absorption of the laser light by the liquid slightly ahead of the front. We show that the laser spot perturbation technique can be efficiently used as a tool for mapping out the large range of accessible lamellar spacings and for creation of desired patterns such as smooth spacing gradients or tilt domains.

XRD analysis provides evidence that the temperature of the alkali halide substrate during deposition, substrate lattice constant, and molecular length affect the molecular orientations within these adsorbed ultrathin films.

The photoluminescence quantum yield of PbTe spherical NCs was measured to be as high as 52 +/- 2%. We also report the first known observation of efficient multiple exciton generation (MEG) from single photons absorbed in PbTe NCs. Finally, we report calculated longitudinal and transverse Bohr radii for PbS, PbSe, and PbTe NCs to account for electronic band anisotropy.

The identification capability of charged hadrons is greatly extended compared with that achieved by TPC and TOF separately. Particle spectra from p + p, d + Au collisions at root S-NN = 200 GeV and Au + Au collisions at root S-NN = 62.4 GeV are used to develop the methods. The transverse momentum ()T) ranges of pi, and p(p) identification are from similar to 0.3GeV/c to similar to 10GeV/c. The high p(T) reach is limited by statistics in current data sets. An important conceptual advance was developed to identify electrons by using a combination of dE/dx in TPC and velocity information from the TOF detectors, which is important for future low-mass dilepton program at STAR.

The flexibility of the algorithm is demonstrated by use of FCS simulations and single-molecule photon antibunching experiments. Execution speed is comparable to the commonly used multiple-tau correlation technique. Wide bin spacings are possible that allow for real-time software calculation of correlations, even for high count rates. (c) 2006 Optical Society of America.

Experiments using a channel guided laser wakefield accelerator at Lawrence Berkeley National Laboratory (LBNL) have demonstrated that near mono-energetic 100 MeV-class electron beams can be produced with a 10 TW laser system. Analysis, aided by particle-in-cell simulations, as well as experiments with various plasma lengths and densities, indicate that tailoring the length of the accelerator, together with loading of the accelerating structure with beam, is the key to production of mono-energetic electron beams. Increasing the energy towards a GeV and beyond will require reducing the plasma density and design criteria are discussed for an optimized accelerator module. The current progress and future directions are summarized through comparison with conventional accelerators, highlighting the unique short-term prospects for intense radiation sources based on laser-driven plasma accelerators.

These are important for practical laser-driven accelerators. STELLA used inverse free electron lasers, which were chosen primarily for convenience. Nevertheless, the STELLA approach can be applied to other laser acceleration methods, in particular, laser-driven plasma accelerators. STELLA is now conducting experiments on laser wakefield acceleration (LWFA). Two novel LWFA approaches are being investigated. In the first one, called pseudo-resonant LWFA, a laser pulse enters a low-density plasma where nonlinear laser/plasma interactions cause the laser pulse shape to steepen, thereby creating strong wakefields. A witness e-beam pulse probes the wakefields. The second one, called seeded self-modulated LWFA, involves sending a seed e-beam pulse into the plasma to initiate wakefield formation. These wakefields are amplified by a laser pulse following shortly after the seed pulse. A second e-beam pulse (witness) follows the seed pulse to probe the wakefields. These LWFA experiments will also be the first ones driven by a CO2 laser beam. C1 STI Optron Inc, Bellevue, WA 98004 USA. Brookhaven Natl Lab, Upton, NY 11973 USA.

Two novel techniques of laser particle acceleration are discussed. The first scheme is based on a solid-state accelerating structure powered by a short pulse CO2 laser. The planar structure consists of two SiC films, separated by a vacuum gap, grown on Si wafers. Particle acceleration takes place inside the gap by a surface electromagnetic wave excited at the vacuum/SiC interface. Laser coupling is accomplished through the properly designed Si grating. This structure can be inexpensively manufactured using standard microfabrication techniques and can support accelerating fields well in excess of 1 GeV m(-1) without breakdown. The second scheme utilizes a laser beatwave to excite a high-amplitude plasma wave, which accelerates relativistic particles. The novel aspect of this technique is that it takes advantage of the nonlinear bi-stability of the relativistic plasma wave to drive it close to the wavebreaking.

Because the LB algorithm yields a simple collide-stream sequence it has been extensively applied to Navier-Stokes flows, but its MHD Counterpart is less well known in the plasma physics community. several plasma problems that should be amenable to LB are discussed. In particular, Landau damping-a collisionless kinetic phenomenon of wave-particle interaction-can be Studied by LB since non-local macroscopic closures have been generated by plasma physicists. The parallel performance of 2D LB codes for MHD are presented, including scaling performance on the Earth Simulator. (c) 2005 Elsevier B.V. All rights reserved.

As is well known, the ESR response is strongly affected by the local nuclear fields induced by dynamic nuclear polarization. The peculiar resistance responses resulting from dynamic nuclear polarization and NMR were numerically simulated on the basis of the rate equation for the Zeeman order of nuclei in the vicinity of the 2D electron system. The simulations, which include the nuclear spin diffusion, provide an opportunity to visualize the propagation of the nuclear spin polarization into the Al(x)Gal(1-x)As barriers of the quantum wells.

Phys. 138 (1982) 78] is applied to measurements of bulk permittivity on a composite system with various levels of filler concentration, in order to extract structural information such as shape and spatial arrangement of the filler particles. The composites are paraffin wax filled with metal-coated hollow glass micro-spheres. The inclusions have an outer layer of dielectric which prevents conduction between them. In the spectral density analysis, the dielectric permittivity of the matrix phase is used as measured. The permittivity of the particles is deduced by application of a mixture formula to the measured permittivity of the composite system with low concentrations of filler. The calculated spectral density functions for each concentration level indicate that the topology of the mixtures undergoes a transition when the inclusion concentration reaches approximately 25%.

The model is based on the minimum of the magnetic anisotropy energy with respect to the orientation of the magnetic moment of the film. Magnetic anisotropy energies are taken as the sum of shape anisotropy, magnetocrystalline anisotropy and magnetoelastic anisotropy, the two latter ones being present as constant surface and variable volume contributions. Other than anisotropy materials constants, readily available from literature, only information about the strain in the films for the determination of the magnetoelastic anisotropy energy is required. Application of the epitaxial Bain path allows to express the strain in the film in terms of substrate lattice constant and film lattice parameter, and thus to obtain an approximate closed expression for the reorientation thickness in terms of lattice mismatch. The model can predict the critical spin reorientation transition thickness with surprising accuracy. (c) 2006 Elsevier B.V. All rights reserved.

However, phosphate minerals naturally accumulate sonic heavy metals that may cause additional contamination of the environment if used improperly. Nine commercially available phosphate materials were evaluated for remediation of contaminated soil based on solubility, concentration of metal/metalloid impurities, and leachability Of impurity metal/metalloids. The phosphate materials consisted of three groups: processed (i.e., fertilizers), mined (rock phosphates from different formations), and biogenic (ground fish bone). Processed and mined rock phosphates contained relatively high total concentrations of As, Co, Cr, and Cu but did not exceed the RCRA toxicity characteristic leaching procedure (TCLP) limits. Biogenic apatite contained much lower metal concentrations than processed and mined rock phosphate and was appreciably more soluble. By combining biogenic and mined phosphate it is possible to obtain a wide range of phosphate release rates, permitting rapid immobilization of contaminants while providing a slow release of phosphate for continued long-term treatment.

For pure components self-assembly proceeds more slowly for C14 than for C18. In both cases after equilibrium is reached islands of tilted molecules cover a similar fraction of the surface. Images of films formed by mixtures of molecules acquired before equilibrium is reached (short ripening time at room temperature) show only islands with the height corresponding to C18 with many pores. After a long ripening time, when equilibrium is reached, islands of segregated pure components are formed. (c) 2006 Elsevier B.V. All rights reserved.

Although both drugs have similar therapeutic potencies, the stimulatory effect of AMP on extracellular dopamine (ECF DA) is greater than that of MP. We compared extracellular effects directly against synaptic changes. ECF DA was assessed by microdialysis in freely moving rodents and synaptic dopamine (DA) was measured using PET and [C-11]-raclopride displacement in rodents and baboons. Microdialysis data demonstrated that MP (5.0 mg/kg, i.p.) increased ECF DA 360% +/- 31% in striatum, which was significantly less than that by AMP (2.5 mg/kg, i.p.; 1398% +/- 272%). This fourfold difference was not reflected by changes in synaptic DA. In fact, rodent PET studies showed no difference in striatal [C-11]-raclopride binding induced by AMP (2.5 mg/kg, i.p.; 25% +/- 4% reduction) compared with that by MP (5.0 mg/kg, i.p.; 21% +/- 4% reduction). Primate PET experiments also showed no differences between AMP (0.5 mg/kg, i.v.; 24% +/- 4% reduction) and MP (1.0 mg/kg, i.v.; 25% +/- 7% reduction) induced changes in [C-11]-raclopride binding potential. The similar potencies of MP and AMP to alter synaptic DA, despite their different potencies in raising ECF DA, could reflect their different molecular mechanisms.

Ion trap (IT), as well as triple quadrupole (TQ) instruments, have been used for mass analysis. Secondary ion images have been acquired using time-of-flight (TOF) S-SIMS. The generation of molecular adduct ions from thin and thick layers on the mineral substrates has been investigated using KBr as a simple model system. Results show that molecular adducts of KBr can be indeed detected from the spiked materials. However, the concentrations of the spiking solutions have to be significantly larger than expected from the surface area measured by gas adsorption techniques. In addition imaging analysis has evidenced that the detection of adduct ions in the mass spectra directly relates to the presence of local micro-crystallites. (c) 2005 Elsevier B.V.

Using a multi-frequency, complex sawtooth modulation in the quasi - isothermal mode disclosed for the first time that the uncorrected apparent heat capacity C-p = A(phi)(A(T delta)omega) of the liquid polyethylene fiber increases with increasing frequency (A(phi) is the differential heat-flow rate and AT, is the sample temperature). The frequency-dependent heat capacity cannot be represented by the expression: C-p = A(phi)(A(T),v omega)[1 + (tau v omega)(2]0.5) because of a negative tau(2). The results were later confirmed by independent measurements on single sinusoidal quasi-isothermal TMDSC on the same material. The error is caused by shrinking of the fiber, which deforms the sample pan. (c) 2005 Elsevier B.V. All rights reserved. C1 Univ Tennessee, Dept Chem, Knoxville, TN 37996 USA.

It is found that the sintering of individual passivated gold nanoparticles under electron irradiation is local and mainly depends on the sensitivity of the passivating ligands to the electron beam. A multilayer film is less stable than monolayer film, consistent with the enhanced generation of secondary electrons. The observations also reveal a significant difference between the sintering of passivated nanciparticles and bare metal particles, especially regarding the size effect on the sintering rate. The formation of a neck between adjacent nanoparticles further indicates a mechanism driven by surface diffusion rather than Ostwald ripening at the initial sintering stage.

The dendritic platinum nanostructures can be reproducibly prepared on a gram scale, allowing their characterization by N-2 adsorption as well as transmission electron microscopy (TEM), cross-section TEM, scanning TEM (STEM), scanning electron microscopy (SEM), and x-ray diffraction (XRD). Because of the high surface area, these nanoporous Pt dendrites have potential applications as catalysts and electrocatalysts. Control over the size of these platinum dendrites was realized by seeding their autocatalytic growth at the beginning of the reaction either by addition of platinum nanoparticles or by growing the seed particles using a porphyrin photocatalyst. The results support a mechanism based on dendritic growth from the seeds by an autocatalytic metal-reduction reaction occurring at the surface of the platinum dendrites rather than a mechanism based on formation of nanoparticles that subsequently aggregate.

Forests of silicon pillars of sub-500 nm diameter and with an aspect ratio up to 10 were fabricated using a combination of the nanosphere lithography and deep reactive ion etching techniques. The nanosphere etch mask coated silicon substrates were etched using oxygen plasma and a time-multiplexed 'Bosch' process to produce nanopillars of different length, diameter and separation. Scanning electron microscopy data indicate that the silicon etch rates with the nanoscale etch masks decrease linearly with increasing aspect ratio of the resulting etch structures.

The surface structure, composition, and morphology of the thin films deposited were analysed using high resolution transmission electron microscopy (TEM) and high angle annular dark field scanning TEM imaging and energy dispersive x-ray measurements. The films deposited were extremely thin, on the order of 3-5 nm, and uniformly covered all the alumina nanoparticles. X-ray diffraction was used to investigate the phases and structures of the thin films deposited. At the heat treatment temperature of 600 degrees C, cubic Y(2)O(3) nanocrystals were found in the film while as-coated layers exhibited mainly amorphous features. As the heat treatment temperature increased to 750 'C, the amorphous thin film became well crystallized. Optical properties of Eu(3+) doped Y(2)O(3) films were characterized by fluorescence spectroscopy. Strong photoluminescence was observed in the sample annealed at 750 'C, frorn the fluorescence of Eu(3+) ions in a well-crystallized film, consistent with the x-ray diffraction and TEM observations.

This procedure employs direct evaluations of the orientation dependent interaction energies at the CASPT2/cc-pvdz level within variable reaction coordinate transition state theory (VRC-TST). One-dimensional corrections to these energies are obtained from CAS+1+2/aug-cc-pvtz calculations for CH3 + CH3 along its combination reaction path. Direct CAS+1+2/aug-cc-pvtz calculations demonstrate that, at least for the purpose of predicting the kinetics, the corrected CASPT2/cc-pvdz potential energy surface is all accurate approximation to the CAS+1+2/aug-cc-pvtz surface. Furthermore, direct trajectory simulations, performed at the B3LYP/6-31G* level, indicate that there is little local recrossing of the optimal VRC transition state dividing surface. The corrected CASPT2/cc-pvdz potential is employed in obtaining direct VRC-TST kinetic predictions for the self and cross combinations of methyl, ethyl, iso-propyl, and tert-butyl radicals. Comparisons with experiment suggest that the present dynamically corrected VRC-TST approach provides quantitatively accurate predictions for the capture rate. Each additional methyl substituent adjacent to a radical site is found to reduce the rate coefficient by about a factor of two. In each instance, the rate coefficients are predicted to decrease quite substantially with increasing temperature, with the more sterically hindered reactants having a more rapid decrease. The simple geometric mean rule, relating the capture rate for the cross reaction to those for the self-reactions, is in remarkably good agreement with the more detailed predictions. With suitable generalizations the present approach should be applicable to a wide array of radical-radical combination reactions. C1 Sandia Natl Labs, Livermore, CA 94551 USA.

Direct absorption of UVB by DNA is central in albino animal models, but melanin-pigmented models have shown major contributions by wavelengths longer than UVB that are thought to be mediated by photosensitized oxidant production. The only model for which the action spectrum of melanoma causation is known is a genetically melanoma-susceptible specific cross of Xiphophorus fish. We used electron paramagnetic resonance to quantitatively detect the UV induction of reactive melanin radicals in situ in the melanin-containing cells in the skin of this model and derived the action spectrum for melanin-photosensitized oxidant production (Phi(ox)). This action spectrum was identical to that for melanoma induction (Phi(mel)). These results confirm the hypothesis that melanin-photosensitized radical production is the major causative step of melanoma in this model and demonstrate that the wavelengths and mechanisms of melanoma causation in different models are dependent on the presence of melanin. This approach should be applicable to humans, thus providing an accurate surrogate for Phi(mel) for prevention studies.

The special section also highlights topics that are important and exciting enough to compel researchers to engage in collaborative synthesis activities. This introductory paper provides a brief overview of nine papers that are included in this special section, which discuss the synthesis of tools, data, concepts, theories, or approaches across disciplines and scales. The wide range of topics that are explored include groundwater quality, river restoration, water management, nitrogen cycling, and Earth surface dynamics. Collectively, the special section papers illustrate that the challenge to deal effectively with complex water problems is not purely a scientific, technological, or socioeconomic one; it is instead a complex, 21st century problem that requires coordinated synthesis.

Extraction of layer-specific magnetic hysteresis loops from an array of 1-mu m dots allows us to separate the influence of inter- and intralayer interactions. Double layer (NiFe/Co) dots show evidence of identical vortex formation in both layers while with the spacer layer the direct coupling between the two magnetic layers is removed, and dipolar field contribution becomes significant so that the vortex formation in both layers is suppressed.

Pulsed electron spin resonance shows that spin echo decay is sensitive to the dopant depths, and the interface quality. At 5.2 K, a spin decoherence time, T-2, of 0.3 ms is found for profiles peaking 50 nm below a Si/SiO2 interface, increasing to 0.75 ms when the surface is passivated with hydrogen. These measurements provide benchmark data for the development of devices in which quantum information is encoded in donor electron spins. (c) 2006 American Institute of Physics.

The prototype device consists of naturally doped n-type ZnO nanowites grown on top of a (100) p-silicon substrate by the bottom-up growth process. The diameter of the nanowires is in the range of 70-120 nm, and the length is controlled by the growth time. The isolation is achieved by using spin-on glass (SOG) that also works as the foundation of the top electrode. The current-voltage (I-V) characteristics show the typical rectifying behavior of heterojunctions, and the photodiode exhibits response of similar to 0.07A/W for UV light (365 nm) under a 20 V reverse bias.

Much of present uncertainty in forcing of climate change is due to uncertainty in the relations between aerosol microphysical and optical properties and their radiative influences ( direct effects) and between microphysical properties and their ability to serve as cloud condensation nuclei at given supersaturations ( indirect effects). This paper introduces a special section that reports on a field campaign conducted at the Department of Energy Atmospheric Radiation Measurement site in north central Oklahoma in May 2003, examining these relations using in situ airborne measurements and surface-, airborne-, and space-based remote sensing.

It is shown that the ECMWF analysis reasonably represents the dynamic and thermodynamic structures of the large-scale systems that affected the NSA during M-PACE. The model-analyzed near-surface horizontal winds, temperature, and relative humidity also agree well with the M-PACE surface measurements. Given the well-represented large-scale fields, the model shows overall good skill in predicting various cloud types observed during M-PACE; however, the physical properties of single-layer boundary layer clouds are in substantial error. At these times, the model substantially underestimates the liquid water path in these clouds, with the concomitant result that the model largely underpredicts the downwelling longwave radiation at the surface and overpredicts the outgoing longwave radiation at the top of the atmosphere. The model also overestimates the net surface shortwave radiation, mainly because of the underestimation of the surface albedo. The problem in the surface albedo is primarily associated with errors in the surface snow prediction. Principally because of the underestimation of the surface downwelling longwave radiation at the times of single-layer boundary layer clouds, the model shows a much larger energy loss ( - 20.9 W m(-2)) than the observation ( - 9.6 W m(-2)) at the surface during the M-PACE period.

We consider three possible models for the geometry of relativistic blast-waves (spherical outflows, non-spreading jets and spreading jets), two possible dynamical regimes for the forward shock (adiabatic and fully radiative), and we take into account a possible angular structure of the outflow and delayed energy injection in the blast-wave to identify the models which reconcile the X-ray light-curve decay with the slope of the X-ray continuum for each of the above three afterglow phases. By piecing together the various models for each phase in a way that makes physical sense, we identify possible models for the entire X-ray afterglow. The major conclusion of this work is that a long-lived episode of energy injection in the blast-wave, during which the shock energy increases at t(1.0 +/- 0.5), is required for five afterglows and could be at work in the other four as well. For some afterglows, there may be other mechanisms that can explain the t < 400 s fast falling-off X-ray light curve (e.g. the large-angle gamma-ray burst emission), the 400 s to 5 h slow decay (e.g. a structured outflow), or the steepening at 0.2-2 day (e.g. a jet-break, a collimated outflow transiting from a wind with a r(-3) radial density profile to a homogeneous or outward-increasing density region). Optical observations in conjunction with the X-ray can distinguish among these various models. Our simple tests allow the determination of the location of the cooling frequency relative to the X-ray domain and, thus, of the index of the electron power-law distribution with energy in the blast-wave. The resulting indices are clearly inconsistent with a universal value. C1 Los Alamos Natl Lab, Los Alamos, NM 87545 USA. Penn State Univ, Dept Astron & Astrophys, University Pk, PA 16802 USA.

The grating had 5000 grooves/mm, an effective blaze angle of 14 degrees, and was gold coated. The efficiencies in the two polarization orientations (TM and TE) were measured in the 1.5-5.0 nm wavelength range and were compared with the efficiencies calculated using the PCGrate-SX code. The TM and TE efficiencies differ, offering the possibility of performing unique science studies of astrophysical, solar, and laboratory sources by exploiting the polarization sensitivity of the off-plane grating.

Using the XOR interferometer, we measure the refractive indices of silicon and ruthenium, essential materials for extreme-ultraviolet lithography. Both materials are tested at wavelength (13.4 nm) and across silicon's L-2 (99.8 eV) and L-3 (99.2 eV) absorption edges. We further extend this direct phase measurement method into the soft-x-ray region, where measurements of chromium and vanadium are performed around their L-3 absorption edges at 574.1 and 512.1 eV, respectively. These are the first direct measurements, to our knowledge, of the real part of the index of refraction made in the soft-x-ray region. (c) 2006 Optical Society of America.

The structural properties of the films are investigated using extreme ultraviolet and x-ray reflectometry and transmission electron microscopy. Thermal stability is investigated in films annealed to as high as 300 degrees C. Because of their superior thermal stability, relatively high reflectance, and narrower spectral bandpass, Si/Tb multilayers are identified as optimal candidates for solar physics imaging applications, where the peak response can be tuned to important emission lines such as 0 v near 63.0 nm and Mg x near 61.0 nm. We describe our experimental procedures and results, discuss the implications of our findings, and outline prospects for improved performance. (c) 2006 Optical Society of America.

We demonstrate that magnification perturbations are dominated by perturbers found within roughly a tidal radius of an image and that sizable magnification perturbations may arise from small, coherent contributions from several substructures within the lens halo. The rms fluctuation of the magnification perturbation is similar to 10% - 20%, and both the average and rms perturbations are sensitive to the mass spectrum and density profile of the perturbers. Interestingly, we find that relative to a smooth model of the same mass, the average magnification in clumpy models is lower ( higher) than that in smooth models for positive- parity ( negative- parity) images. This is opposite from what is observed if one assumes that the image magnification predicted by the best- fit smooth model of a lens is a good proxy for what the observed magnification would have been if substructures were absent. While it is possible for this discrepancy to be resolved via nonlinear perturbers, we argue that a more likely explanation is that the assumption that the best- fit lens model is a good proxy for the magnification in the absence of substructure is not correct. We conclude that a better theoretical understanding of the predicted statistical properties of magnification perturbations by CDM substructure is needed in order to affirm that CDM substructures have been unambiguously detected.

FLAMEX is the first deep, wide-area, near-infrared survey to image in both the J and K-s filters, and is larger than any previous NIR survey of comparable depth. The intent of FLAMEX is to facilitate the study of galaxy and galaxy cluster evolution at 1 < z < 2 by providing rest-frame optical photometry for the massive galaxy population at this epoch. This effort is designed to yield a public data set that complements and augments the suite of existing surveys in the NDWFS fields. We present an overview of FLAMEX and initial results based on similar to 150,000 K-s-selected sources in the Bootes field. We describe the observations and reductions, quantify the data quality, and verify that the number counts are consistent with results from previous surveys. Finally, we comment on the utility of this sample for detailed study of the ERO population, and present one of the first spectroscopically confirmed z > 1 galaxy clusters detected using the joint FLAMEX, NDWFS, and Spitzer IRAC Shallow Survey data sets.

Like most CAIs, relict CAIs are O-16 enriched (Delta O-17 < -20 parts per thousand) compared to their host chondrules (Delta O-17 > -9 parts per thousand). Hibonite in a relict CAI from the ungrouped carbonaceous chondrite Adelaide has a large excess of radiogenic Mg-26 (Mg-26*) from the decay of Al-26, corresponding to an initial Al-26/Al-27 ratio [(Al-26/Al-27)(I)] of (3.7 +/- 0.5) x 10(-5); in contrast, melilite in this CAI and plagioclase in the host chondrule show no evidence for Mg-26*[(Al-26/Al-27)(I) of < 5 x 10(-6)]. Grossite in a relict CAI from the CH carbonaceous chondrite PAT 91546 has little Mg-26*, corresponding to a (Al-26/Al-27)(I) of (1.7 +/- 1.3) x 10(-6). Three other relict CAIs and their host chondrules from the ungrouped carbonaceous chondrite Acfer 094, CH chondrite Acfer 182, and H3.4 ordinary chondrite Sharps do not have detectable Mg-26* [(Al-26/Al-27)(I) < 1 x 10(-5), <(4-6) x 10(-6), and < 1.3 x 10(-5), respectively]. Isotopic data combined with mineralogical observations suggest that relict CAIs formed in an O-16-rich gaseous reservoir before their host chondrules, which originated in an O-16-poor gas. The Adelaide CAI was incorporated into its host chondrule after 26Al had mostly decayed, at least 2 Myr after the CAI formed, and this event reset Al-26-Mg-26 systematics.

Spectroscopic analysis indicates that excellent synthetic control was established for the exclusive formation Of a pseudotetrahedral monovanadate (VO4) Structure on all catalyst surfaces. Another V/SBA 15 catalyst was prepared via conventional incipient wetness impregnation (WI) with aqueous NH4VO3. A spectroscopic investigation of this catalyst revealed the presence of monovanadate and polyvanadate species along with small domains Of V2O5. The TMP materials behave as single-site catalysts in the selective oxidation of methane to formaldehyde LIP to a V coverage of 0.47 V nm(-2) and demonstrate superior activity compared with the WI catalyst. A space-time yield of 5.84 kg(CH2O) kg(cat)(-1) h(-1) cat was observed. more than twice the highest value previously reported. (c) 2005 Elsevier Inc. All rights reserved.

Three CeO2 supports with different crystal sizes and surface areas were examined. The Surface areas of these supports increases in the order of CeO2-1 (74 m(2)/g) < CeO2-II (92 m(2)/g) < CeO2-III (154 m(2)/g) but their crystallite sizes were about 10.2, 29.3, and 6.5 nm, respectively. The properties of Ni-Rh/CeO2 catalysts were investigated by XRD, TPR, H-2 chemisorption, and in situ XPS techniques. The Rh metal dispersion increased while the Ni metal dispersion decreased with decreasing crystallite sizes of CeO2. TPR Studies revealed the existence of a Rh-CeO2 metal-support interaction as well as Ni-Rh interaction in the Ni-Rh bimetallic catalyst supported on CeO2-III with a crystallite size of about 6.5 nin. The in Situ XPS Studies corroborated the TPR results. The reduced Ni and Rh species were reversibly oxidized, suggesting the existence of Ni-Rh redox species rather than NiRh surface alloy in the present catalyst system. The Rh species became highly dispersed when the crystallite size of CeO2 Support was smaller. Comparing the catalytic performance in the OSR of ethanol with the properties of the catalysts demonstrated that both ethanol conversion and H-2 selectivity increased and the selectivity for undesirable byproducts decreased with increasing Rh metal dispersion. Best catalytic performance for OSR was achieved by supporting Ni-Rh bimetallic catalysts on the nanocrystalline CeO2-III. The Ni-Rh/CeO2-III catalyst exhibited stable activity and selectivity during on-stream operations at 450 degrees C and as well as at 600 degrees C. (c) 2006 Elsevier Inc. All rights reserved.

Under the dynamics, this system may execute transitions between in-phase and out-of-phase states. For satellite communications and high-speed data transfer the transition times should be reduced to their shortest possible duration. In this paper, we apply optimal control theory to find the values of various laser parameters (e.g. the amplitude of the injected field, detunings, and coupling constants) which minimize the transient times between out-of-phase and in-phase states. The effect of each parameter is shown to be independent of the other two, and the transient time is shown to be a strictly increasing function of detuning and a strictly decreasing function of the coupling constant and amplitude of the injected field. The effect of initial conditions on transient times is also analysed. Published in 2005 by John Wiley & Sons, Ltd.

For the case of a single fluctuator we evaluate explicitly an exact expression for the phase-memory decay in the echo experiment with a resonant ac excitation. The echo signal as a function of time shows a sequence of plateaus. The position and the height of the plateaus can be used to extract the fluctuator switching rate gamma and its coupling strength v. At small times the logarithm of the echo signal is proportional to t(3). The plateaus disappear when the decoherence is induced by many fluctuators. In this case the echo signal depends on the distribution of the fluctuators parameters. According to our analysis, the results significantly deviate from those obtained in the Gaussian model as soon as v greater than or similar to gamma. C1 Univ Oslo, Dept Phys, N-0316 Oslo, Norway.

AIMD shows that 11.6 A diameter hydroxylated silica pores are relatively stable in water, whereas amine groups on functionalized pore surfaces abstract silanol protons, turning into NH3+. Free energy calculations using an ab initio parametrized force field show that the hydroxylated pores strongly attract Na+ and repel Cl- ions. Pores lined with NH3+ have the reverse surface charge polarity. Finally, studies of ions in carbon nanotubes suggest that hydration of Cl- is more strongly frustrated by pure confinement effects than Na+. C1 Sandia Natl Labs, Albuquerque, NM 87185 USA.

We have used x-ray reflectivity to study a molecular liquid, tetrakis(2-ethylhexoxy)silane. When cooled to T/T-c approximate to 0.25 (well above the freezing point for this liquid), density oscillations appear at the surface. Lateral order within the layers is liquidlike. Our results confirm theoretical predictions that a surface-layered state will appear even in dielectric liquids at sufficiently low temperatures, if not preempted by freezing.

The NMR results agree very well with the two spin wave stiffness constants observed at small q values in the spin wave dispersion curves [Phys. Rev. B 67, 214430 (2003)]. This picture is probably related to a yet undetermined charge and orbital superstructure occurring in the ferromagnetic insulating state of the La0.875Sr0.125MnO3 compound.

For photon energies that result in carrier multiplication, these distributions are non-Poissonian and are characterized by two dominant exciton multiplicities that are determined by the ratio of photon energy to NC energy gap. For certain photon energies, we produce photoexcited NC ensembles with a nearly pure single multiplicity that can be tuned from 1 to 7. This result can find applications ranging from lasing and nonlinear optics to photovoltaics and photocatalysis. C1 Los Alamos Natl Lab, Div Chem, CPCS, Los Alamos, NM 87545 USA.

The ground state consists of nearly half-metallic bilayers stacked antiferromagnetically with a weak coupling. Out of plane transport is very strongly suppressed by the antiferromagnetic alignment, which can be destroyed in favor of ferromagnetism at low energy cost. Furthermore, the spin transport in the ferromagnetic state is highly unusual; opposite sign spin polarizations are found for currents in plane and out of plane.

These tribological properties are studied using a polycrystalline silicon nanotractor device, which provides abundant, quantitative information about friction and wear at an actual microelectromechanical system (MEMS) interface. This in situ approach to measuring tribological properties of MEMS, combined with high-resolution atomic force microscope (AFM) images of wear tracks, provides insight into the effects of different MEMS surface processing on wear. In particular, monolayer coatings have a significant positive effect, while surface texturing does not strongly affect performance. (c) 2005 Elsevier B.V. All rights reserved.

The photodissociation of bromoform in the 12-18 eV energy range results in several products, among which are the CH(A(2)Delta) and CH(B-2 Sigma) radicals. Vibrational and rotational state distributions of the CH(A(2)Delta) are determined from their fluorescence spectra. From the threshold photon energy above which emission from the CH(A(2)Delta) radicals is observed, the most likely process leading to CH(A) formation is CHBr3 -> CH + 3Br rather than CHBr3 -> CH + Br + Br-2. The rotational Boltzmann temperatures in the CH(A -> X) emission spectra for v' = 0 and v' = I range between 1570 and 3650 K, depending on the excitation photon energy. From the high rotational excitation, the results suggest that the mechanism for the loss of three bromine atoms is most likely sequential. A small negative emission anisotropy of the CH(A) radicals [(I-par - I-per)/(I-par + 2I(per)) = -0.024 +/- 0.005] is constant across the action spectrum; a small net absorption dipole of CHBr3 in the vacuum ultraviolet is parallel to the 3-fold symmetry axis of the CHBr3 molecule. The state distributions of the CH(A 2 A) radicals from multiphoton dissociation of bromoform using the 266 nm output (three photons) of a femtosecond laser (Boltzmann temperatures: T-v'=0(rot) = 4250 +/- 300 K; T-v'=1(rot) = 3100 +/- 550 K) are compared to those from the single photon dissociation results (Boltzmann temperatures: T-v'=1(rot) = 3650 +/- 150 K; T-v'(rot) = 2400 +/- 200 K) at the same total excitation energy under collision free conditions. The analysis of the CH(A) rotational populations shows hotter rotational populations for the femtosecond experiment, also suggesting sequential dissociation of the bromoform in the femtosecond experiment. The duration of the femtosecond laser pulse is approximately 180 fs, setting a limit on the time scales for the multiple dissociations. C1 Univ Calif Berkeley, Dept Chem, Berkeley, CA 94720 USA.

Potential energy curves were calculated with the aug-cc-pVTZ basis set, and with and without a correction for basis set superposition error (BSSE). Additional calculations were performed with other correlation consistent basis sets to extrapolate the Ar-CF4 potential energy minimum to the complete basis set (CBS) limit. Both the size of the basis set and BSSE have substantial effects on the Ar + CF4 potential. Calculations with the aug-cc-pVTZ basis set, and with a BSSE correction, appear to give a good representation of the BSSE corrected potential at the CBS limit. In addition, MP2 theory is found to give potential energies in very good agreement with those determined by the much higher level CCSD(T) theory. Two model analytic potential energy functions were determined for Ar + CF4. One is a fit to the aug-ccpVTZ calculations with a BSSE correction. The second was derived by fitting an average BSSE corrected potential, which is an average of the CCSD(T)/aug-cc-pVTZ potentials with and without a BSSE correction. These analytic functions are written as a sum of two-body potentials and excellent fits to the ab initio potentials are obtained by representing each two-body interaction as a Buckingham potential.

Furthermore, little is known about enols' flame chemistry. Enol formation in low-pressure flames takes place in the preheat zone, and its precursors are most likely fuel species or the early products of fuel decomposition. The OH + ethene reaction has been shown to dominate ethenol production in ethene flames although this reaction has appeared insufficient to describe ethenol formation in all hydrocarbon oxidation systems. In this work, the mole fraction profiles of ethenol in several representative low-pressure flames are correlated with those of possible precursor species as a means for judging likely formation pathways in flames. These correlations and modeling suggest that the reaction of OH with ethene is in fact the dominant source of ethenol in many hydrocarbon flames, and that addition-elimination reactions of OH with other alkenes are also likely to be responsible for enol formation in flames. On this basis, enols are predicted to be minor intermediates in most flames and should be most prevalent in olefinic flames where reactions of the fuel with OH can produce enols directly.

Both the bursts themselves and their afterglows have been predicted to be visible out to redshifts of z approximate to 20, and therefore to be powerful probes of the early Universe(1,2). The burst GRB 000131, at z = 4.50, was hitherto the most distant such event identified(3). Here we report the discovery of the bright near-infrared afterglow of GRB 050904 (ref. 4). From our measurements of the near-infrared afterglow, and our failure to detect the optical afterglow, we determine the photometric redshift of the burst to be z = 6.39(-0.12)(+0.11) (refs 5-7). Subsequently, it was measured(8) spectroscopically to be z = 6.29 +/- 0.01, in agreement with our photometric estimate. These results demonstrate that GRBs can be used to trace the star formation, metallicity, and reionization histories of the early Universe.

Various strongly interacting atomic systems are successfully treated as a collection of quasiparticles with weak or no interactions. However, there are interesting limitations to this description: in some systems the very existence of quasiparticles cannot be taken for granted. Like unstable elementary particles, quasiparticles cannot survive beyond a threshold where certain decay channels become allowed by conservation laws; their spectrum terminates at this threshold. Such quasiparticle breakdown was first predicted for an exotic state of matter-super-fluid He-4 at temperatures close to absolute zero, a quantum Bose liquid where zero-point atomic motion precludes crystallization(1-4). Here we show, using neutron scattering, that quasiparticle breakdown can also occur in a quantum magnet and, by implication, in other systems with Bose quasiparticles. We have measured spin excitations in a two-dimensional quantum magnet, piperazinium hexachlorodicuprate (PHCC)(5), in which spin-1/2 copper ions form a non-magnetic quantum spin liquid, and find remarkable similarities with excitations in superfluid He-4. We observe a threshold momentum beyond which the quasiparticle peak merges with the two-quasiparticle continuum. It then acquires a finite energy width and becomes indistinguishable from a leading-edge singularity, so that excited states are no longer quasiparticles but occupy a wide band of energy. Our findings have important ramifications for understanding excitations with gapped spectra in many condensed matter systems, ranging from band insulators to high-transition-temperature superconductors(6).

Comparing particle with antiparticle decays, we obtain the first measurement of the CP violation parameter A equivalent to alpha((Lambda) over bar c) + alpha((Lambda) over bar c)/alpha(Lambda c) - alpha(Lambda c). We obtain alpha(Lambda c) = -0.78 +/- 0.16 +/- 0.19 and A = -0.07 +/- 0.19 +/- 0.24 where errors are statistical and systematic. (c) 2006 Elsevier B.V. All rights reserved.

DISTRIBUTIONS; QCD ANALYSIS; EP; CALORIMETER; POLARIMETER; SCATTERING; NUCLEON; PROGRAM; PHYSICS AB Data taken with positrons of different longitudinal polarisation states in collision with unpolarised protons at HERA are used to measure the total cross sections of the charged current process, e(+) p -> nu X, for negative four-momentum transfer squared Q(2) > 400 GeV2 and inelasticity gamma < 0.9. Together with the corresponding cross section obtained from the previously published unpolarised data, the polarisation dependence of the charged current cross section is measured for the first time at high Q(2) and found to be in agreement with the Standard Model prediction.

Starting from the high-precision CD-Bonn 2000 nucleon-nucleon (NN) interaction, wave functions of Be-7 and B-8 bound states are obtained in basis spaces up to 10h Omega and used to calculate channel cluster form factors (overlap integrals) of the 8B ground state with Be-7+p. Due to the use of the harmonic oscillator (HO) basis, the overlap integrals have incorrect asymptotic properties. We fix this problem in two alternative ways. First, by a Woods-Saxon (WS) potential solution fit to the interior of the NCSM overlap integrals. Second, by a direct matching with the Whittaker function. The corrected overlap integrals are then used for the Be-7(p, gamma)B-8 S-factor calculation. We study the convergence of the S-factor with respect to the NCSM HO frequency and the model space size. Our S-factor results are in agreement with recent direct measurement data. (c) 2006 Elsevier B.V. All rights reserved. C1 Univ Arizona, Dept Phys, Tucson, AZ 85721 USA.

Four data sets were collected on glass bead packs sintered to differing bulk densities; each of these data sets contains just over 225 million voxels (661 x 661 x 517), with voxel resolution of 3.34 mu m. The other four data sets were collected from a single sample of natural sandstone. For the natural sandstone, three data sets were collected from different subvolumes within the sample, with these three data sets identical in size and resolution to those acquired for the sintered glass bead packs. A fourth data set was collected for one of the same subvolumes but at twice the resolution; this data set contains just over 1.6 billion voxels (1327 x 1327 x 920), with voxel resolution of 1.67 mu m. Following processing to extract binary descriptions of the two-phase ( solid and pore) structure, the image data are analyzed to calculate porosity and specific surface area. The binarized image data are applied directly in massively parallel numerical simulations of single-phase fluid flow performed using the lattice Boltzmann method; development of novel boundary conditions to facilitate efficient handling of these very large data sets is also described. The permeabilities predicted from 1 to 3 mm(3) image volumes characterized at a length scale of similar to 1.7 - 3.4 mu m are compared to experimental measurements of intrinsic permeability performed at bench conditions on standard core-sized samples (25.4 mm in diameter x 50.8 mm in length, or similar to 26 cm(3)). The macroscopic permeability computed from the image data agree remarkably well with the experimentally measured bulk permeability over several orders of magnitude range in permeability and equate to over 4 orders of magnitude scale-up. The results provide insight on the representative volume and length scales necessary to characterize geometrically complex porous media and predict fluid transport properties at the macroscale.

Protonation with 1 equiv of p-cyanoanilinium tetrafluoroborate in acetone-d(6) at -80 degrees C results in ligand protonation and the formation of endo (4a) and exo (4b) isomers of trans-[HFe(PNHP)(dmpm)(CH3CN)]- (BPh4)(2). The endo isomer undergoes rapid intramolecular proton/hydride exchange with an activation barrier of 12 kcal/mol. The exo isomer does not exchange. Studies of the reaction of 3 with a weaker acid (anisidinium tetrafluoroborate) in acetonitrile indicate that a rapid intermolecular proton exchange interconverts isomers 4a and 4b, and a pK(a) value of 12 was determined for these two isomers. Protonation of 3 with 2 equiv of triflic acid results in the protonation of both the PNP ligand and the metal hydride to form the dihydrogen complex [(H-2)Fe(PNHP)(dmpm)((CHCN)-C-3)](3+), 11. Studies of related complexes [HFe(PNP)(dmpm)(CO)](+) (12) and [HFe(depp)(dmpm)(CH3CN)]1 (10) (where depp is bis(diethylphosphino)propane) confirm the important roles of the pendant base and the ligand trans to the hydride ligand in the rapid intra- and intermolecular hydride/proton exchange reactions observed for 4. Features required for an effective proton relay and their potential relevance to the iron-only hydrogenase enzymes are discussed. C1 Natl Renewable Energy Lab, Golden, CO 80401 USA.

Monodisperse platinum nanoparticles of 1.7-7.1 nm have been synthesized by alcohol reduction methods and incorporated into mesoporous SBA-15 silica during hydrothermal synthesis. Characterization of the Pt/SBA-15 catalysts suggests that Pt particles are located within the surfactant micelles during silica formation leading to their dispersion throughout the silica structure. After removal of the templating polymer from the nanoparticle surface, Pt particle sizes were determined from monolayer gas adsorption measurements. Infrared studies of CO adsorption revealed that CO exclusively adsorbs to atop sites and red-shifts as the particle size decreases suggesting surface roughness increases with decreasing particle size. Ethylene hydrogenation rates were invariant with particle size and consistent with a clean Pt surface. Ethane hydrogenolysis displayed significant structure sensitivity over the size range of 1-7 nm, while the apparent activation energy increased linearly up to a Pt particle size of similar to 4 nm and then remained constant. The observed rate dependence with particle size is attributed to a higher reactivity of coordinatively unsaturated surface atoms in small particles compared to low-index surface atoms prevalent in large particles. The most reactive of these unsaturated surface atoms are responsible for ethane decomposition to surface carbon. The ability to design catalytic structures with tunable properties by rational synthetic methods is a major advance in the field of catalyst synthesis and for the development of accurate structure-function relationships in heterogeneous reaction kinetics.

Collision-induced dissociation studies of [UO2(A)(3)(O-2)](+) showed initial loss of acetone, followed by elimination of O-2, which suggested that O-2 was bound more strongly than the third acetone ligand, but less strongly than the second, Similar behavior was observed for complexes in which water was substituted for acetone. Binding of dioxygen to [UO2](+) containing zero, one, or four ligands did not occur, nor did it occur for analogous ligated U(IV)O-2 or U(VI)O-2 ions. For example, only addition of acetone and/or H2O occurred for the U(VI) species [UO2OH]+, with the ligand addition cascade terminating in formation of [UO2OH(A)(3)](+). Similarly, the U(IV) species [UOOH](+) added donor ligands, which produced the mixed-ligand complex [UOOH(A)(3)(H2O)](+) as the preferred product at the longest reaction times accessible. Since dioxygen normally functions as an electron acceptor, an alternative mode for binding dioxygen to the cationic U(V)O-2 center is indicated that is dependent on the presence of an unpaired electron and donor ligands in the uranyl valence orbitals.

Using resonance Raman (RR) spectroscopy, the structural properties of the ferrochelatase-bound porphyrins are examined, especially with respect to the porphyrin deformation occurring in the environment of the active site. This deformation is thought to be a key step in the enzymatic insertion of ferrous iron into the porphyrin ring to make heme. Our previous RR spectroscopic studies of binding of porphyrin to murine ferrochelatase led us to propose that the wild-type enzyme induces porphyrin distortion even in the absence of the metal ion substrate. Here, we broaden this view by presenting evidence that the degree of a specific nonplanar porphyrin deformation contributes to the catalytic efficiency of ferrochelatase and its variants. The results also suggest that the conserved Trp256 (murine ferrochelatase numbering) is partially responsible for the observed porphyrin deformation. Binding of porphyrin to the ferrochelatase variants causes a decrease in the intensity of RR out-of-plane vibrational mode gamma(15), a saddling-like mode that is strong in the wild-type enzyme. In particular, the variant with a catalytic efficiency 1 order of magnitude lower than that of the wild-type enzyme is estimated to produce less than 30% of the wild-type saddling deformation. These results suggest that specific conserved loop residues (especially Trp256) are directly involved in the saddling of the porphyrin substrate.

For most choices of M, lithiation beyond x = 1 results in either decomposition or transformation to a nonlayered structure. In this article, we present first-principles calculations, on the basis of the GGA+U method, to compare addition, decomposition (with metal oxide and lithia as products), and displacement (with metal and lithia as products) reactions when an additional Li is added to LiMO2. We consider M = Mn, Co, and Ni, as well as equiatomic binary mixtures of these elements. Although the displacement reaction is energetically (or thermodynamically) favored, the addition and decomposition reactions are apparently more favored kinetically, as it is the latter that are observed experimentally. The ratio of the open-circuit cell voltage to the magnitude of the reaction energy, V-0/Delta E-r, is higher for systems such as M = Mn0.5Ni0.5, for which an addition reaction occurs, than for those such as M = Co, which undergoes decomposition.

A Kalman filter predictor bias correction SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article ID ATMOSPHERIC DATA ASSIMILATION; BRITISH-COLUMBIA; ANALYSIS SCHEME; TERRAIN AB [1] The Kalman filter (KF) is a recursive algorithm to estimate a signal from noisy measurements. In this study it is tested in predictor mode, to postprocess ozone forecasts to remove systematic errors. The recent past forecasts and observations are used by the KF to estimate the future bias. This bias correction is calculated separately for, and applied to, 12 different air quality (AQ) forecasts for the period 11 - 15 August 2004, over five monitoring stations in the Lower Fraser Valley, British Columbia, Canada, a population center in a complex coastal mountain setting. The 12 AQ forecasts are obtained by driving an AQ Model (CMAQ) with two mesoscale meteorological models ( each run at two resolutions) and for three emission scenarios ( Delle Monache et al., 2006). From the 12 KF AQ forecasts an ensemble mean is calculated (EK). This ensemble mean is also KF bias corrected, resulting in a high-quality estimate (KEK) of the short-term (1- to 2-day) ozone forecast. The Kalman filter predictor bias-corrected ensemble forecasts have better forecast skill than the raw forecasts for the locations and days used here. The corrected forecasts are improved for correlation, gross error, root mean square error, and unpaired peak prediction accuracy. KEK is the best and EK is the second best forecast overall when compared with the other 12 forecasts. The reason for the success of EK and KEK is that both the systematic and unsystematic errors are reduced, the first by Kalman filtering and the second by ensemble averaging.

A new ensemble design SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article ID AIR-QUALITY FORECAST; LOWER FRASER VALLEY; MODEL; PERFORMANCE; SYSTEM AB [1] A new Ozone Ensemble Forecast System (OEFS) is tested as a technique to improve the accuracy of real-time photochemical air quality modeling. The performance of 12 different forecasts along with their ensemble mean is tested against the observations during 11 - 15 August 2004, over five monitoring stations in the Lower Fraser Valley, British Columbia, Canada, a population center in a complex coastal mountain setting. The 12 ensemble members are obtained by driving the U. S. Environmental Protection Agency (EPA) Models-3/Community Multiscale Air Quality Model (CMAQ) with two mesoscale meteorological models, each run at two resolutions (12- and 4-km): the Mesoscale Compressible Community (MC2) model and the Penn State/NCAR mesoscale (MM5) model. Moreover, CMAQ is run for three emission scenarios: a control run, a run with 50% more NOx emissions, and a run with 50% fewer. For the locations and days used to test this new OEFS, the ensemble mean is the best forecast if ranked using correlation, gross error, and root mean square error and has average performance when evaluated with the unpaired peak prediction accuracy. Ensemble averaging removes part of the unpredictable components of the physical and chemical processes involved in the ozone fate, resulting in a more skilful forecast when compared to any deterministic ensemble member. There is not one of the 12 individual forecasts that clearly outperforms the others on the basis of the four statistical parameters considered here. A lagged-averaged OEFS is also tested as follows. The 12-member OEFS is expanded to an 18- member OEFS by adding the second day from the six 12-km "yesterday'' forecasts to the "today'' ensemble forecast. The 18-member ensemble does not improve the ensemble mean forecast skill. Neither correlation nor a relationship between ensemble spread and forecast error is evident.

It is shown that the 'commonsense' criterion for mapping two different shapes by imposing the equality of the demagnetization factors for equal aspect ratios often results in large errors. We propose a general method for the rigorous determination of the equivalent ellipsoid. The cases of the exact equivalent ellipsoids for discs, cylinders with elliptical cross section and prisms are worked out and discussed. C1 Brookhaven Natl Lab, Upton, NY 11973 USA.

Recent advances in thin film growth have produced single crystal epitaxial layers of InN which are similar in structural quality to GaN films made under similar conditions and which can have electron concentrations below 1 x 10(18) cm(-3) and mobilities exceeding 2000 cm(2) (Vs)(-1). Optical absorption, photoluminescence, photo-modulated reflectance and soft x-ray spectroscopy measurements were used to establish that the room temperature band gap of InN is 0.67 +/- 0.05 eV. Experimental measurements of the electron effective mass in InN are presented and interpreted in terms of a non-parabolic conduction band caused by the k (.) p interaction across the narrow gap. Energetic particle irradiation is shown to be an effective method to control the electron concentration, n, in undoped InN. Optical Studies Of irradiated InN reveal a lame Burstein-Moss shift of the absorption edge with increasing n. Fundamental Studies of the energy levels of defects in InN and of electron transport are also reviewed. Finally, the current experimental evidence for p-type activity in Mg-doped InN is evaluated.

In general, information on the re-entry environment is limited, meaning that two or more models for this environment may be consistent with the available information. This defines a collection of candidate models; each model in the collection is consistent with the available information. Methods from decision theory are applied to select the optimal member from the collection. A performance criterion, based on postulated utility functions, is used in the selection process. Herein, we model the re-entry environment as a stochastic process in both space and time. Information on the probability law of the process is limited. The candidate models form a class of non-Gaussian, stationary, stochastic processes. It is shown that the response of a critical internal component is sensitive to assumptions on the unknown properties of the input; the response of the component is therefore used as the performance criterion to select an optimal model for the re-entry environment.

Four POSS macromers, R'R7Si8O12, were designed to contain a single silane functional group, R', which was used to graft onto the dangling 1,2-butadienes in the polybutadiene soft block and seven identical organic groups, R. Small-angle X-ray scattering and theological techniques were used to study the effect of sterically similar, yet electronically different, organic R groups, cyclopentyl (Cp), cyclohexyl (Cy), cyclohexenyl (Cye), and phenyl (Ph), on the morphology of SBS triblock copolymer and the order-disorder transition behavior. It was observed that POSS with phenyl moiety, when grafted to the polybutadiene (PB) phase, appears to show favorable interaction with the polystyrene (PS) phase; effectively, the Ph-POSS is plasticizing the SBS due to an effect whereby the Ph-POSS is at least partially solvated by the PS phase. This causes a significant decrease in the overall lamellae d spacing and the order-disorder transition temperature, T-ODT, with increasing amounts of Ph-POSS attachment. As we change the POSS moiety to that of Cye, Cy, and Cp, the interaction between POSS-PS weakens, and the d spacing and TODT become less dependent on the amounts of POSS attachment. At the highest POSS loadings investigated (20 wt %), there is a change to a perforated layer morphology, resulting in an increase of TODT relative to the 10 wt % POSS-grafted copolymers for Cp, Cy, and Cye POSS moieties.

Fourier transforms of coordinate data from MD simulations are used to produce reciprocal space "fingerprints" of atomic pair distance correlations that are characteristic of the ensemble and are the direct numerical analogues of experimental solution x-ray diffraction (SXD). SXD experiments and MD simulations were carried out to test the ability of experiment and simulation to resolve sequence-dependent modifications in helix conformation for B-form DNA. SXD experiments demonstrated that solution-state poly(AT) and poly(A)-poly(T) duplex DNA sequences exist in ensembles close to canonical B-form and B'-form structures, respectively. In contrast, MD simulations analyzed in terms of SXD fingerprints are shown to deviate from experiment, most significantly for poly(A)-poly(T) duplex DNA. Compared with experiment, MD simulation shortcomings were found to include both mismatches in simulated conformer structures and number population within the ensembles. This work demonstrates an experimental approach for quantitatively evaluating MD simulations and other coordinate models to simulate biopolymer structure in solution and suggests opportunities to use solution diffraction data as experimental benchmarks for developing supramolecular force fields optimized for a range of in situ applications.

The brown deletion complex comprises > 28 independent genome rearrangements, which have been used to identify several functional loci on chromosome 4 required for normal embryonic and postnatal development. We have constructed a 172-bacterial artificial chromosome contig that spans this 22-megabase (Mb) interval and have produced a contiguous, finished, and manually annotated sequence from these clones. The deletion complex is strikingly gene-poor, containing only 52 protein-coding genes (of which only 39 are supported by human homologues) and has several further notable genomic features, including several segments of > 1 Mb, apparently devoid of a coding sequence. We have used sequence polymorphisms to finely map the deletion breakpoints and identify strong candidate genes for the known phenotypes that map to this region, including three lethal loci (14Rn1, 14Rn2, and 14Rn3) and the fitness mutant brown-associated fitness (baf). We have also characterized misexpression of the basonuclin homologue, Bnc2, associated with the inversion-mediated coat color mutant white-based brown (B-w). This study provides a molecular insight into the basis of several characterized mouse mutants, which will allow further dissection of this region by targeted or chemical mutagenesis.

The influence of nitrogen incorporation on the optical absorption is investigated. The diamond films are characterized by photothermal deflection spectroscopy and temperature dependent spectrally resolved photoconductivity. An onset of absorption at about 0.8 eV in undoped films is attributed to transitions from pi to pi states introduced into the band gap by the high amount of sp(2) bonded carbon at the grain boundaries. Incorporation of nitrogen leads to a strong absorption in the whole energy spectrum, as a result of the increasing number of sp(2) carbon atoms. The effect of surface states has been observed in the high energy region of the spectrum. Transitions to the conduction band tail and photothermal ionization processes account for the observed onset at 4.4 eV. Photocurrent quenching at about 3.3 eV is observed in the case of samples grown from a hydrogen-rich CH4/H-2 gas phase. (c) 2006 American Institute of Physics.

Here, we report a similar method to fabricate solid-state nanopores using the electron source of a conventional field-emission scanning electron microscope (FESEM) instead. Micromachining was used to create initial pore diameters between 50 nm and 200 nm, and controlled pore shrinking to sub 10 nm diameters was performed subsequently during in situ processing in the FESEM. Noticeably, different shrinking behavior was observed when using irradiation from the electron source of the FESEM than the TEM. Unlike previous reports of TEM mediated pore shrinkage, the mechanism of pore shrinkage when using the FESEM could be a result of surface defects generated by radiolysis and subsequent motion of silicon atoms to the pore periphery.

Relative to bulk powder, nanophosphors of particle size similar to 25-100 nm diameter exhibit redshifts of the photoluminescence excitation and emission spectra, reduced self absorption, enhanced light output, and medium-dependent radiative lifetime. Photoluminescence data are consistent with reduced symmetry of the P2(1)/c structure and are not necessarily related to reduced dimensionality of the nanophosphor. In contrast, medium-dependent lifetime and enhanced light output are attributed to nanoscale behavior. Perturbation of the Ce ion electric field is responsible for the variable lifetime.

Although this force is extremely small and its effect on the solid can be ignored, it plays a significant role for flexible surfaces such as microcantilevers. A gold-coated silicon microcantilever and a dodecanethiol coated silicon microcantilever were used to detect real-time formation of nanobubbles on their surfaces when exposed to air-rich water. As air nanobubbles form on the surfaces of the cantilever, the cantilever undergoes bending, and we relate this to the vertical component of surface energy in Young's equation. This implies that the vertical component of the surface tension should be considered for flexible solid surfaces, and the formation of nanobubbles should be avoided when cantilevers are used as sensors to avoid artifacts.

Transmission electron microscopy shows that these ultralow-density (similar to 99.2% porous) nanostructures are formed by a continuous network of elongated amorphous GeO2 nanoligaments, similar to 15-20 nm in diameter and similar to 50-200 nm in length. As a result, monoliths exhibit a high surface area of similar to 60 m(2) g(-1). A comparison of soft x-ray absorption spectra at Ge L-3 and O K edges with theoretical densities of states reveals that the electronic structure of aerogels is similar to that of hexagonal GeO2, indicating a (distorted) tetrahedral environment of Ge atoms in the amorphous nanostructure.

While quantum dots and laser dyes both emit in the visible range at room temperature, the Stokes shift of the dyes is significantly larger. The scintillation output of both systems was studied under alpha irradiation and interpreted using a combination of energy loss and photon transport Monte Carlo simulation models. The comparison of the two systems, which allows the quantification of the role played by the Stokes shift in the scintillation output, opens up exciting possibilities for a new class of scintillators that would take advantage of the limitless assembly of nanocrystals in large, transparent, and sturdy matrices.

In situ high-temperature x-ray diffraction from the precursor films containing pure BaF2 as well as pseudobinary BaF2-Y, BaF2-Cu, and Y-Cu mixtures and heat treated in water vapor under reduced conditions revealed that the transient BaF2-based superstructures, similar to those observed during formation of Ba2Cu3O7-x, develop even from the pure BaF2 precursor. These superstructures results from the dissolution of oxygen in BaF2 leading to formation of the oxyfluoride phase, Ba(F2-2x square(x))O-x, with an ordered arrangement of O, F, and F vacancies.

Single-crystal X-ray diffraction shows that these have the orthorhombic CeCu2-type structure, lmma,Z = 4 (a = 5.140(1), 5.104(1), 5.145(1) angstrom; b = 8,317(2), 8.461(2), 8.373(2) angstrom; c = 8.809(2), 8.580(2), 8.715(2) angstrom, respectively). The structure consists of a four-linked honeycomblike polyanion (4(2)6(3)8) of (3)(infinity)[Tr-2](2-) (Tr = ln or Tl) with encapsulated Ba2+ cations. The Au or Hg randomly replace Tr in a single type of site. The two gold phases exhibit appreciable nonstoichiometry ranges. Band calculations (EHTB) demonstrate that the three compounds are electron-poor and metallic, and the latter has been confirmed for 1 through resistivity and magnetic susceptibility measurements. The orthorhombic structure of 1 contrasts with the hexagonal structure of BaTl2 (Caln(2)-type, P6(3)/mmc), a change that appears to be driven by substitution of the smaller Au atoms into the polyanion network. Relativistic effects for the heavier Au and Hg are evidently responsible for decreases in lattice parameters and bond lengths from Baln(2) to those in isostructural 2 and 3.

With equal amounts of the reagents, two terminal OEt groups are replaced to form [Ta(OEt)(2)](2)(mu-oEt)(2)-(mu-OSiMe2OSiMe2O)(2), 1, whereas with an excess of diol, the remaining terminal OEt groups are also replaced but with a trisiloxanediolato unit to form [Ta(OSiMe(2)OSiMe(2)OSime(2)O)]2(mu-OEt)2(mu-OSiMe2OSiMe2O)2, 2. Complexes 1 and 2 catalyze the transformation of HOSM2OSM2OH to polysiloxanes. Thermal treatment of 1 results in the formation of a 1:2 mixture of Ta2O5/SiO2; no new phases are observed.

The nuclear and Coulomb potentials are used to obtain the tunneling probability and, in one model variant, also the knocking frequency. The model contains only one parameter. We compare this approach employing several modem mean-field parametrizations to experimental data and to the semi-empirical Viola-Seaborg systematics. We extrapolate our model to superheavy nuclei where assumptions entering semi-empirical approaches might lose validity. (c) 2005 Elsevier B.V. All rights reserved.

This effect takes the mathematical form of rapidly moving traveling wave solutions of the BK equation, which we investigate by numerical simulations. These traveling wave solutions are different from those governing the transition to saturation, which propagate towards the ultraviolet. The infrared wave speed, formally infinite for the leading order QCD kernel, is determined by higher order corrections. This mechanism could play a role in the rapid decrease of the mean free path in the Color Glass Condensate scenario for heavy ion collisions. (c) 2005 Elsevier B.V. All rights reserved.

The cycling stability of the optical switching depends upon preservation of the integrity of the Pd catalyst overlayer. Alloying between Mg and Pd causes interdiffusion of the two elements, and leads to degradation in switching speed and eventual deactivation. Incorporation of a thin niobium oxide barrier layer between the active magnesium alloy film and the Pd layer substantially improves the cycling stability of the mirror. (c) 2005 Elsevier B.V.

The structures define the conformation of the bound inhibitors and suggest the residues involved in substrate binding and catalysis at the dicarboxylate site. In particular they support the role of Arg(297) as a general base catalyst accepting a proton in the dehydrogenation of succinate. The dicarboxylate ligand in oxaloacetate-containing crystals appears to be the same as that reported for Shewanella flavocytochrome c treated with fumarate. The plant and fungal toxin 3-nitropropionic acid, an irreversible inactivator of succinate dehydrogenase, forms a covalent adduct with the side chain of Arg(297). The modification eliminates a trypsin cleavage site in the flavoprotein, and tandem mass spectroscopic analysis of the new fragment shows the mass of Arg(297) to be increased by 83 Da and to have the potential of losing 44 Da, consistent with decarboxylation, during fragmentation.

We use multiwavelength time series of data taken simultaneously with the Swedish Vacuum Solar Telescope (SVST) on La Palma, the TRACE satellite, and the MDI instrument on SOHO. We find that long before the magnetic pore is formed, the chromosphere and transition region show a high activity above the future site of pore formation: rising but not yet visible magnetic flux exerts a strong pressure on the overlying plasma generating highly collimated plasma flows seen in the Ha images. About the time when the magnetic pores are formed and the Ha surges bifurcate into the established arc-like flows, a system of compact coronal loops is formed, showing direct connection between the motions associated with the evolving magnetic fields and the coronal structure formation.

Dilute solutions of benzene-based p-QDMs, p-xylylene (1), a-methyl-p-xylylene (10), and 2,5-dimethyl-p-xylylene (11) can be prepared by fluoride-induced elimination of trimethylsilyl acetate from the appropriate precursor. It has been found that these solutions are stable enough to allow these reactive p-QDMs to be observed by H-1 NMR spectroscopy at room temperature. For the first time, the 13 C NMR spectrum of p-QDM 1 was observed. After several hours at room temperature, these p-QDMs form dimers, trimers, and insoluble oligomers. Formation of trimers provides evidence that p-QDMs 1, 10, and 11 dimerize by a stepwise mechanism involving dimeric diradicals as intermediates. C1 Iowa State Univ, Dept Chem, Ames, IA 50011 USA.

Coupling between olefins and NH-3,4-dihydroquinazoline was found to occur consecutively with heterocycle dehydrogenation in the presence of a Rh(I)/PCy3/HCl catalyst. The reaction was used to develop an effective method for the synthesis of 2-substituted quinazolines through an oxidative workup step. The regiocontrolled synthesis and Rh-catalyzed cyclization of alkene-tethered 3,4-dihydroquinazolines are also described. Applying this method, the second total synthesis of vasicoline was achieved. The key Rh-catalyzed cyclization step was made possible by the use of a rigid bicyclic phosphine ligand. The synthesis further demonstrates a challenging Cu-catalyzed amidation of an ortho-substituted aryl chloride. C1 Univ Calif Berkeley, Dept Chem, Berkeley, CA 94720 USA.

For non-Uniform, high order filters with bounded moments the magnitude of the commutator errors is shown to be of the same order as that of the turbulent stress fluxes. Consequently, one cannot reduce the size of the commutator errors independently of the turbulent stress terms by any judicious construction of such filter operators. Independent control over the commutator errors compared to the turbulent stress fluxes can, instead, be obtained by appropriately restricting the spatial variations of the filter-width and filter-skewness. For situations in which the dynamical consequences of the commutator errors are significant, e.g., near solid boundaries, explicit similarity modelling for the commutator errors is proposed, including the application of Leray regularization. The performance of this commutator error parametrization is illustrated for the one-dimensional Burgers equation. The Leray approach is found to capture the filtered flow with higher accuracy than conventional similarity modelling, which is particularly relevant for large filter-width variations.

association with W Bosons in p(p)over-bar collisions at root s = 1.96 TeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID STANDARD MODEL AB We present a search for Higgs bosons decaying into b (b) over bar and produced in association with W bosons in p (p) over bar collisions at root s =1.96 TeV. This search uses 320 pb(-1) of the data set accumulated by the upgraded Collider Detector at Fermilab. Events are selected that have a high-transverse momentum electron or muon, missing transverse energy, and two jets, at least one of which is consistent with the hadronization of a b quark. Both the number of events and the dijet mass distribution are consistent with standard model background expectations, and we set 95% confidence level upper limits on the production cross section times branching ratio for the Higgs boson or any new particle with similar decay kinematics. These upper limits range from 10 pb for m(H)=110 GeV/c(2) to 3 pb for m(H)=150 GeV/c(2). C1 Acad Sinica, Inst Phys, Taipei 11529, Taiwan. Argonne Natl Lab, Argonne, IL 60439 USA.

B-c(+/-) meson SO PHYSICAL REVIEW LETTERS LA English DT Article ID B-C MESON; HADRONIC PRODUCTION; SEARCH; DETECTOR; UPGRADE; STATES AB We report the first evidence for a fully reconstructed decay mode of the B-c(+/-) meson in the channel B-c(+/-)-> J/psi pi(+/-), with J/psi ->mu(+)mu(-). The analysis is based on an integrated luminosity of 360 pb(-1) in p (p) over bar collisions at 1.96 TeV center of mass energy collected by the Collider Detector at Fermilab. We observe 14.6 +/- 4.6 signal events with a background of 7.1 +/- 0.9 events, and a fit to the J/psi pi(+/-) mass spectrum yields a B-c(+/-) mass of 6285.7 +/- 5.3(stat)+/- 1.2(syst) MeV/c(2). The probability of a peak of this magnitude occurring by random fluctuation in the search region is estimated as 0.012%. C1 Univ Illinois, Urbana, IL 61801 USA.

We generate lepton number through the gravitational anomaly in the lepton number current. The source term comes from elliptically polarized gravity waves that are produced during inflation if the inflaton field contains a CP-odd component. The amount of matter asymmetry generated in our model can be of realistic size for the parameters within the range of some inflationary scenarios and grand unified theories.

Kraichnan's prediction of a -5/3 spectrum with constant, negative energy flux is verified in our simulations of 2D Navier-Stokes equations. We observe a similar but shorter range of inverse cascade in laboratory experiments. Our theory predicts, and the data confirm, that inverse cascade results mainly from turbulent stress proportional to small-scale strain rotated by 45 degrees. This "skew-Newtonian" stress is explained by the elongation and thinning of small-scale vortices by large-scale strain which weakens their velocity and transfers their energy upscale.

MODEL AB The ratios of inclusive electron scattering cross sections of He-4, C-12, and Fe-56 to He-3 have been measured at 1 < x(B)< 3. At Q(2)> 1.4 GeV2, the ratios exhibit two separate plateaus, at 1.5 < x(B)< 2 and at x(B)> 2.25. This pattern is predicted by models that include 2- and 3-nucleon short-range correlations (SRC). Relative to A=3, the per-nucleon probabilities of 3-nucleon SRC are 2.3, 3.1, and 4.4 times larger for A=4, 12, and 56. This is the first measurement of 3-nucleon SRC probabilities in nuclei.

At half filling a semimetallic state with small Fermi pockets is induced beyond a threshold tunneling strength. The sign changes in the single electron Green's function relevant for the Luttinger sum rule now take place at surfaces with both zeros and infinities with important consequences for the interpretation of angle-resolved photoemission spectroscopy experiments. Residual interactions between electron and holelike quasiparticles cause a transition to long range order at low temperatures.

The change in conductivity is 100 times larger than that seen previously in any single-phase manganite in zero field. The metallic low-temperature state is similar to x=0.58, but x=0.58 shows no evidence of orbital or charge order.

Measurement of transient spectral holes induced by a 100 fs pump pulse in excitations of the surface dangling-bond states of Si(111)-(7x7) led to a pump-fluence-dependent homogeneous linewidth as broad as similar to 100 meV or a dephasing time as short as 15 fs. The hole-burning spectra also revealed a strong coupling between the localized dangling-bond states and the associated surface phonon mode at 570 cm(-1). Carrier-carrier scattering was responsible for the linear dependence of the dephasing rate on pump fluence, and the carrier screening effect appeared to be weak.

Using in situ low-energy electron microscopy for dynamic observation and high-resolution transmission electron microscopy for structure analysis, we have observed the rapid formation of hexagonal networks of linear "nanofolds" with prismatic cavities on top of layered VSe2 crystals. Their formation results from relaxation of compressive strains which build up during Cu intercalation into a thin surface layer.

We use ATLAS as an example. The lead ion is treated as a source of (coherently produced) photons with energies and intensities greater than those of equivalent ep collisions at the DESY collider HERA. We find very large rates for both inclusive and diffractive production that will extend the HERA x range by nearly an order of magnitude for similar virtualities. We demonstrate that it is possible to reach the kinematic regime where nonlinear effects are larger than at HERA. C1 Penn State Univ, University Pk, PA 16802 USA.

We have also synthesized a recoverable nitride of iridium under nearly the same conditions of pressure and temperature as PtN2. Although it has the same stoichiometry, it exhibits much lower structural symmetry. Preliminary results suggest that the bulk modulus of this material is also very large.

Along its path, it cools by about 5 degrees C over 1350 km. Based on an eddy permitting simulation using the Parallel Ocean Program model, we find that 70% of the heat advected into the coastal region off Western Australia by the narrow mean jet is transferred to the ocean interior through eddy heat fluxes. The eddy fluxes are associated with processes operating at submonthly timescales and despite the current's clear seasonal variability, seasonal rectification plays little role in the mean heat balance. The 43 TW transferred offshore by eddies is the primary means by which the ocean interior (22 degrees S-34 degrees S and east of 107 degrees E) is warmed and the Leeuwin Current cooled. The Leeuwin Current jet and the eddies allow air-sea fluxes to transfer over 40 W m(-2) of heat to the atmosphere in the southeast Indian Ocean.

The early method of ion mobility spectrometry (IMS) distinguished ions by absolute mobility that depends on the collision cross section with buffer gas atoms. The more recent technique of field asymmetric waveform IMS (FAIMS) measures the difference between mobilities at high and low electric fields. Coupling IMS and FAIMS to soft ionization sources and mass spectrometry (MS) has greatly expanded their utility, enabling new applications in biomedical and nanomaterials research. Here, we show that time-dependent electric fields comprising more than two intensity levels could, in principle, effect an infinite number of distinct differential separations based on the higher-order terms of expression for ion mobility. These analyses could employ the hardware and operational procedures similar to those utilized in FAIMS. Methods up to the 4th or 5th order (where conventional IMS is 1st order and FAIMS is 2nd order) should be practical at field intensities accessible in ambient air, with still higher orders potentially achievable in insulating gases. Available experimental data suggest that higher-order separations should be largely orthogonal to each other and to FAIMS, IMS, and MS.

We use density functional theory (DFT) to investigate the chemistry of one such system (i.e., 1,4-diphenyl-butadiyne (DPB) in contact with Pd(110) and Pd(111) surfaces). Reaction pathways and the energetics of important processes are explored, including H-2 adsorption, dissociation and migration on the metal surface, the DPB-metal interaction, the energetics of H uptake, and the effects of impurities such as CO and CO2 on H chemistry. We find that (i) strong aromatic-metal interaction leads to significant binding strength of the DPB molecule to both Pd surfaces, especially the (110); (ii) H-2 molecules readily dissociate on the Pd surface into H-radicals, which get taken up by alkyne triple bonds; (iii) CO has strong binding to the metal surface, but interacts weakly with H radicals; and (iv) CO2 binds weakly to the metal surface, but could potentially lead to interesting chemical reactions with H.

We find that large extensions induce chain ordering in the direction of applied stress. During the extension, we also find that voids are created via a cavitation mechanism. At the end of our simulations, by visual inspection, we distinguish cavity, fibril, and amorphous regions that coexist together. The surrounding material about the formed cavities is fibril-like, while the remaining material remains amorphous. We also estimate the surface energy of the cavity. The cavity size continually increases in the dimension of applied stress but saturates in the lateral dimensions, most likely due to the finite size of the system. Despite chain orientation and ordering in the direction of applied stress, crystallization is absent in the time and stress range of our simulation. This study represents a baseline for the future study of mechanical properties of PDMS melts enriched with fillers under stress.

The computational approach, which employs modified functionals with short-ranged Hartree-Fock exchange, was first tested in calculations of the structural and bonding properties of the water dimer and cyclic water trimer. Liquid water simulations were performed at the state point of 350 K at the experimental density. Simulations included three different hybrid functionals, a meta-functional, four gradient-corrected functionals, and the local density and Hartree-Fock approximations. It is found that hybrid functionals are superior in reproducing the experimental structure and dynamical properties as measured by the radial distribution function and self-diffusion constant when compared to the pure density functionals. The local density and Hartree-Fock approximations show strongly over- and understructured liquids, respectively. Hydrogen bond analysis shows that the hybrid functionals give slightly smaller average numbers of hydrogen bonds than pure density functionals but similar hydrogen bond populations. The average molecular dipole moments in the liquid from the three hybrid functionals are lower than those of the corresponding pure density functionals.

Numerous properties such as interfacial width, hydrogen bond populations, dipole moments, and correlation times will be characterized with identical schemes to draw useful conclusions on the strengths and weakness of the proposed models for interfacial water. Our findings indicate that all models considered in this study yield similar results for the radial distribution functions, hydrogen bond populations, and orientational relaxation times. Significant differences in the models appear when examining both the dipole moments and surface relaxation near the aqueous liquid-vapor interface. Here, the ab initio interaction potential predicts a significant decrease in the molecular dipole moment and expansion in the oxygen-oxygen distance as one approaches the interface in accordance with recent experiments. All classical polarizable interaction potentials show a less dramatic drop in the molecular dipole moment, and all empirical interaction potentials studied yield an oxygen-oxygen contraction as the interface is approached.

Unconventional superconductivity, on the other hand, develops near a phase boundary separating magnetically ordered and magnetically disordered phases(2,3). A maximum in the superconducting transition temperature T-c develops where this boundary extrapolates to zero Kelvin, suggesting that fluctuations associated with this magnetic quantum-critical point are essential for unconventional superconductivity(4,5). Invariably, though, unconventional superconductivity masks the magnetic phase boundary when T < T-c, preventing proof of a magnetic quantum-critical point(5). Here we report specific-heat measurements of the pressure-tuned unconventional superconductor CeRhIn5 in which we find a line of quantum-phase transitions induced inside the superconducting state by an applied magnetic field. This quantum-critical line separates a phase of coexisting antiferromagnetism and superconductivity from a purely unconventional superconducting phase, and terminates at a quantum tetracritical point where the magnetic field completely suppresses superconductivity. The T --> 0 K magnetic field - pressure phase diagram of CeRhIn5 is well described with a theoretical model(6,7) developed to explain field-induced magnetism in the high-T-c copper oxides, but in which a clear delineation of quantum - phase boundaries has not been possible. These experiments establish a common relationship among hidden magnetism, quantum criticality and unconventional superconductivity in copper oxides and heavy-electron systems such as CeRhIn5.

Shoshani, Arie TI Optimizing bitmap indices with efficient compression SO ACM TRANSACTIONS ON DATABASE SYSTEMS LA English DT Article DE performance; algorithms; compression; bitmap index; query processing ID PERFECT HASH FUNCTIONS; RETRIEVAL; ALGORITHM AB Bitmap indices are efficient for answering queries on low-cardinality attributes. In this article, we present a new compression scheme called Word-Aligned Hybrid ( WAH) code that makes compressed bitmap indices efficient even for high-cardinality attributes. We further prove that the new compressed bitmap index, like the best variants of the B-tree index, is optimal for one-dimensional range queries. More specifically, the time required to answer a one-dimensional range query is a linear function of the number of hits. This strongly supports the well-known observation that compressed bitmap indices are efficient for multidimensional range queries because results of one-dimensional range queries computed with bitmap indices can be easily combined to answer multidimensional range queries. Our timing measurements on range queries not only confirm the linear relationship between the query response time and the number of hits, but also demonstrate that WAH compressed indices answer queries faster than the commonly used indices including projection indices, B-tree indices, and other compressed bitmap indices.

The effect of the fabrication process on glass structure and reproducibility of the coating's properties, and the effect of cell culture conditions on the integrity of the coating were assessed. The structure of FGCs was compared to that of the as cast glass used as a top coating. X-ray diffraction (XRD) showed that the fabrication process resulted in 5.9 +/- 3.0 vol.% crystallization, while glass as cast was amorphous. Glass as cast and coatings behaved similarly in simulated body fluid (SBF): an amorphous layer rich in phosphate formed, and it crystallized, over 4 weeks, into apatite-like mineral (Fourier transform infrared spectroscopy (FTIR), XRD, scanning electron microscopy (SEM)). Reproducibility of the fabrication process was tested from three batches of coatings by measuring thickness and crystallinity. MC3T3-E1.4 mouse pre-osteoblast cells were cultured and induced to mineralize on FGCs, either as made or pre-conditioned in SBF. The sub-surface glass silica network in FGCs was compromised by cell culture conditions. A crystalline phosphate was formed during pre-conditioning (XRD, FTIR, and SEM). SBF-pre-conditioning stabilized the coatings. Thus incubation in SBF is recommended to produce a stable coating. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

The structure was determined by multiple-wavelength anomalous dispersion at 2.17 angstrom resolution. The structure is almost entirely beta-sheet; it consists of 15 beta-strands and one short 3(10)-helix and represents a new protein fold. The packing of the two monomers in the asymmetric unit indicates that the biological unit may be a dimer. C1 Univ Washington, Dept Biochem, Seattle, WA 98195 USA.

The orientation relationship between the matrix and the precipitate thin plates was determined as [(1) over bar 010](1 (2) over bar 11)(P)//[010](10 (2) over bar)(m). High-resolution TEM images of the Gd5Ge4 were used to study the crystallographic relationship between the parent and matrix that exists along the interface boundary. The observed planar alignment and microscopic structure of the interface, which consists of ledges and terraces, indicate the presence of invariant line strain. The results are also consistent with the Delta g approach suggested by Zhang and Purdy. A displacive-diffusional mechanism is proposed to explain the rapid formation of the precipitate Gd-5(Ge,Si)(3) plates. Published by Elsevier Ltd on behalf of Acta Materialia Inc.
