CA D0 Collaboration TI Measurement of the differential gamma plus c-jet cross section and the ratio of differential gamma plus c and gamma plus b cross sections in p(p)over-bar collisions at root s=1.96 TeV SO PHYSICS LETTERS B LA English DT Article AB We present measurements of the differential cross section d sigma/dp(T)(gamma) for the associated production of a c-quark jet and an isolated photon with rapidity vertical bar y(gamma)vertical bar < 1.0 and transverse momentum 30 < p(T)(gamma) < 300 GeV. The c-quark jets are required to have vertical bar y(jet)vertical bar < 1.5 and p(T)(jet) > 15 GeV. The ratio of differential cross sections for gamma + c to gamma + b production as a function of p(T)(gamma) is also presented. The results are based on data corresponding to an integrated luminosity of 8.7 fb(-1) recorded with the D0 detector at the Fermilab Tevatron p (p) over bar Collider at root s = 1.96 TeV. The obtained results are compared to next-to-leading order perturbative QCD calculations using various parton distribution functions, to predictions based on the k(T)-factorization approach, and to predictions from the SHERPA and PYTHIA Monte Carlo event generators.

Saccharomyces cerevisiae cannot metabolize xylose due to a lack of xylose-metabolizing enzymes. We developed a rapid and efficient xylose-fermenting S. cerevisiae through rational and inverse metabolic engineering strategies, comprising the optimization of a heterologous xylose-assimilating pathway and evolutionary engineering. Strong and balanced expression levels of the XYL1, XYL2, and XYL3 genes constituting the xylose-assimilating pathway increased ethanol yields and the xylose consumption rates from a mixture of glucose and xylose with little xylitol accumulation. The engineered strain, however, still exhibited a long lag time when metabolizing xylose above 10 g/l as a sole carbon source, defined here as xylose toxicity. Through serial-subcultures on xylose, we isolated evolved strains which exhibited a shorter lag time and improved xylose-fermenting capabilities than the parental strain. Genome sequencing of the evolved strains revealed that mutations in PHO13 causing loss of the Pho13p function are associated with the improved phenotypes of the evolved strains. Crude extracts of a PHO13-overexpressing strain showed a higher phosphatase activity on xylulose-5-phosphate (X-5-P), suggesting that the dephosphorylation of X-5-P by Pho13p might generate a futile cycle with xylulokinase overexpression. While xylose consumption rates by the evolved strains improved substantially as compared to the parental strain, xylose metabolism was interrupted by accumulated acetate. Deletion of ALD6 coding for acetaldehyde dehydrogenase not only prevented acetate accumulation, but also enabled complete and efficient fermentation of xylose as well as a mixture of glucose and xylose by the evolved strain. These findings provide direct guidance for developing industrial strains to produce cellulosic fuels and chemicals.

TI Incommensurate antiferromagnetism in a pure spin system via cooperative organization of local and itinerant moments SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE itinerant magnetism; RKKY interaction; asymmetric line shape ID MAGNETIC-STRUCTURE; METALS; FLUCTUATIONS; POLARIZATION; TRANSITION; SCATTERING; RNI2GE2 AB Materials with strong correlations are prone to spin and charge instabilities, driven by Coulomb, magnetic, and lattice interactions. In materials that have significant localized and itinerant spins, it is not obvious which will induce order. We combine electrical transport, X-ray magnetic diffraction, and photoemission studies with band structure calculations to characterize successive anti-ferromagnetic transitions in GdSi. GdSi has both sizable local moments and a partially nested Fermi surface, without confounding contributions from orbital effects. We identify a route to incommensurate order where neither type of moment dominates, but is rooted in cooperative feedback between them. The nested Fermi surface of the itinerant electrons induces strong interactions between local moments at the nesting vector, whereas the ordered local moments in turn provide the necessary coupling for a spin-density wave to form among the itinerant electrons. This mechanism echoes the cooperative interactions between electrons and ions in charge-density-wave materials, and should be germane across a spectrum of transition-metal and rare-earth intermetallic compounds.

In these "quantum critical" superconductors it has been widely reported that the normal-state properties above the superconducting transition temperature T-c often exhibit anomalous non-Fermi liquid behaviors and enhanced electron correlations. However, the effect of these strong critical fluctuations on the superconducting condensate below Tc is less well established. Here we report measurements of the magnetic penetration depth in heavy-fermion, iron-pnictide, and organic superconductors located close to antiferromagnetic quantum critical points, showing that the superfluid density in these nodal superconductors universally exhibits, unlike the expected T-linear dependence, an anomalous 3/2 power-law temperature dependence over a wide temperature range. We propose that this noninteger power law can be explained if a strong renormalization of effective Fermi velocity due to quantum fluctuations occurs only for momenta k close to the nodes in the superconducting energy gap A(k). We suggest that such "nodal criticality" may have an impact on low-energy properties of quantum critical superconductors.

TI Structure of an actin-related subcomplex of the SWI/SNF chromatin remodeler SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE RSC; X-ray crystallography; protein complex; nucleosome remodeler ID ARP2/3 COMPLEX; NUCLEAR ACTIN; DNA TRANSLOCATION; SACCHAROMYCES-CEREVISIAE; RSC; PROTEINS; GENOME; REFINEMENT; EXPRESSION; MECHANISM AB The packaging of DNA into nucleosomal structures limits access for templated processes such as transcription and DNA repair. The repositioning or ejection of nucleosomes is therefore critically important for regulated events, including gene expression. This activity is provided by chromatin remodeling complexes, or remodelers, which are typically large, multisubunit complexes that use an ATPase subunit to translocate the DNA. Many remodelers contain pairs or multimers of actin-related proteins (ARPs) that contact the helicase-SANT-associated (HSA) domain within the catalytic ATPase subunit and are thought to regulate ATPase activity. Here, we determined the structure of a four-protein subcomplex within the SWI/SNF remodeler that comprises the Snf2 HSA domain, Arp7, Arp9, and repressor of Tyl transposition, gene 102 (Rtt102). Surprisingly, unlike characterized actin-actin associations, the two ARPs pack like spoons and straddle the HSA domain, which forms a 92-angstrom-long helix. The ARP-HSA interactions are reminiscent of contacts between actin and many binding partners and are quite different from those in the Arp2/3 complex. Rtt102 wraps around one side of the complex in a highly extended conformation that contacts both ARPs and therefore stabilizes the complex, yet functions to reduce by similar to 2.4-fold the remodeling and ATPase activity of complexes containing the Snf2 ATPase domain. Thus, our structure provides a foundation for developing models Of remodeler function, including mechanisms of coupling between ARPs and the ATPase translocation activity.

Lipoteichoic acid (LTA), a cell wall polymer of Gram-positive bacteria, consists of 1,3-polyglycerol-phosphate linked to glycolipid. LTA synthase (LtaS) polymerizes polyglycerol-phosphate from phosphatidylglycerol, a reaction that is essential for the growth of Gram-positive bacteria. We screened small molecule libraries for compounds inhibiting growth of Staphylococcus aureus but not of Gram-negative bacteria. Compound 1771 [2-oxo-2-(5-phenyl-1,3,4-oxadiazol-2-ylamino) ethyl 2-naphtho[2,1-b]furan-1-ylacetate] blocked phosphatidylglycerol binding to LtaS and inhibited LTA synthesis in S. aureus and in Escherichla coli expressing ltaS. Compound 1771 inhibited the growth of antibiotic-resistant Gram-positive bacteria and prolonged the survival of mice with lethal S. aureus challenge, validating LtaS as a target for the development of antibiotics.

Tetrapyrroles play a significant role in plastid-to-nucleus retrograde signaling in plants to ensure that nuclear gene expression is attuned to the needs of the chloroplast. Well-known sites of synthesis of chlorophyll for photosynthesis, plant chloroplasts also export heme and heme-derived linear tetrapyrroles (bilins), two critical metabolites respectively required for essential cellular activities and for light sensing by phytochromes. Here we establish that Chlamydomonas reinhardtii, one of many chloro-phyte species that lack phytochromes, can synthesize bilins in both plastid and cytosol compartments. Genetic analyses show that both pathways contribute to iron acquisition from extracellular heme, whereas the plastid-localized pathway is essential for light-dependent greening and phototrophic growth. Our discovery of a bilin-dependent nuclear gene network implicates a widespread use of bilins as retrograde signals in oxygenic photosynthetic species. Our studies also suggest that bilins trigger critical metabolic pathways to detoxify molecular oxygen produced by photosynthesis, thereby permitting survival and phototrophic growth during the light period.

TI 5,10-Dihydroindolo[3,2-b]indole-Based Copolymers with Alternating Donor and Acceptor Moieties for Organic Photovoltaics SO MACROMOLECULES LA English DT Article ID HETEROJUNCTION SOLAR-CELLS; CONJUGATED POLYMER; SIDE-CHAINS; PERFORMANCE; EFFICIENCY; ATROPISOMERISM; MORPHOLOGY; SEPARATION; DESIGN; LEDS AB A series of new donor-acceptor pi-conjugated copolymers incorporating 5,10-dihydroindolo[3,2-b]indole (DINI) as an electron donating unit have been designed, synthesized, and explored in bulk heterojunction solar cells with diketopyrrolopyrrole and thienopyrroledione as the electron accepting units. A significant effect of the size and shape of the pendant alkyl substituents attached to the DINI unit on the optical and electronic properties of the copolymers is described. Our study reveals a good correlation between the theoretical calculations performed on the selected materials and the experimental HOMO, LUMO, absorption spectra, and band gap energies of the corresponding copolymers. The band gaps of the conjugated copolymers can be tailored over 0.4 eV by the electron-withdrawing nature of the different acceptor units to provide better overlap with the solar spectrum, and the energy levels can be tuned similar to 0.2 eV depending on the alkyl substituents employed. For the polymers in this study, a nonoptimized power conversion efficiency as high as 3% was observed.

Additional chemical functionalization schemes can controllably improve selectivity of the carbon nanotube-based sensors; however, the exact transduction mechanism is still under debate. In this article we detail the synthesis and selective response of single-walled carbon nanotubes (SWNTs) functionalized with polyazomethine (PAM) polymer toward the application of a specific trace metal ion detector. The response of the polymer system was compared to shape persistent macrocycle (MAC) comprised of identical ion coordination ligands. While ion detection with rigid MAC/SWNT chemiresistor was comparable to bare SWNT, flexible PAM offers significant SWNT signal amplification, allowing for picomolar detection of Co2+ ions with both selectivity and a fast response. We hypothesized that rearrangement of the flexible PAM on the SWNT network is a sensing mechanism which allows for ultrasensitive detection of metal ions. The electron transfer and polymer rearrangement on the SWNT were studied by a combination of optical spectroscopy and electrical measurements-ultimately allowing for a better understanding of fundamental mechanisms that prompt device response.

TI Chemical Patterns for Directed Self-Assembly of Lamellae-Forming Block Copolymers with Density Multiplication of Features SO MACROMOLECULES LA English DT Article ID THIN-FILMS; NANOPATTERNED SURFACES; DIBLOCK COPOLYMERS; LITHOGRAPHY; DOMAINS; PHOTORESIST; SIMULATIONS; FABRICATION; DIMENSIONS; BRUSHES AB Lamellae-forming polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) films, with bulk period L-0, were directed to assemble on lithographically nanopatterned surfaces. The chemical pattern was comprised of "guiding" stripes of cross-linked polystyrene (X-PS) or poly(methyl methacrylate) (X-PMMA) mats, with width W, and interspatial "background" regions of a random copolymer brush of styrene and methyl methacrylate (P(S-r-MMA)). The fraction of styrene (f) in the brush was varied to control the chemistry of the background regions. The period of the pattern was L-s. After assembly, the density of the features (domains) in the block copolymer film was an integer multiple (n) of the density of features of the chemical pattern, where n = L-s/L-0. The quality of the assembled PS-b-PMMA films into patterns of dense lines as a function of n, W/L-0, and f was analyzed with top-down scanning electron microscopy. The most effective background chemistry for directed assembly with density multiplication corresponded to a brush chemistry (f) that minimized the interfacial energy between the background regions and the composition of the film overlying the background regions. The three-dimensional structure of the domains within the film was investigated using cross-sectional SEM and Monte Carlo simulations of a coarse-grained model and was found most closely to resemble perpendicularly oriented lamellae when W/L-0 similar to 0.5-0.6. Directed self-assembly with density multiplication (n = 4) and W/L-0 = 1 or 1.5 yields pattern of high quality, parallel linear structures on the top surface of the assembled films, but complex, three-dimensional structures within the film.

Pyridine-containing star molecules forming a hydrophobic core/hydrophilic corona unimolecular micelle in acidic solution (pH 3) were alternately deposited with oppositely charged linear sulfonated polystyrene (PSS), yielding microcapsules with LbL shells containing hydrophobic micelles. The surface morphology and internal nanopore structure of the hollow microcapsules were comparatively investigated for shells formed from star polymers with a different numbers of arms (9 versus 22) and varied shell thickness (5, 8, and 11 bilayers). The successful integration of star unimers into the LbL shells was demonstrated by probing their buildup, surface segregation behavior, and porosity. The larger arm star copolymer (22 arms) with stretched conformation showed a higher increment in shell thickness due to the effective ionic complexation whereas a compact, uniform grainy morphology was observed regardless of the number of deposition cycles and arm numbers. Small-angle neutron scattering (SANS) revealed that microcapsules with hydrophobic domains showed different fractal properties depending upon the number of bilayers with a surface fractal morphology observed for the thinnest shells and a mass fractal morphology for the completed shells formed with the larger number of bilayers. Moreover, SANS provides support for the presence of relatively large pores (about 25 nm across) for the thinnest shells as suggested from permeability experiments. The formation of robust microcapsules with nanoporous shells composed of a hydrophilic polyelectrolyte with a densely packed hydrophobic core based on star amphiphiles represents an intriguing and novel case of compartmentalized microcapsules with an ability to simultaneously store different hydrophilic, charged, and hydrophobic components within shells.

The charged triblock copolymers were synthesized by functionalizing poly[(allyl glycidyl ether)-b-(ethylene oxide)-b-(allyl glycidyl ether)] with either guanidinium or sulfonate functional groups. When aqueous solutions (ca. 5-40 wt %) of these oppositely charged polymers were mixed, the electrostatic interactions of the functionalized blocks led to the association of the oppositely charged end-blocks into phase-separated complex coacervate domains bridged by the uncharged, hydrophilic PEO midblock. The resulting structures were studied by small-angle X-ray scattering (SAXS) and dynamic mechanical spectroscopy. The organization of the coacervate domains was shown to affect substantially the viscoelastic properties of the hydrogels, with the storage modulus increasing significantly as the mixtures transformed from a disordered array of domains to an ordered BCC structure with increasing block copolymer concentration. As the polymer concentration was further increased to 30 wt %, a hexagonal structure appeared, which coincided with a 25% drop in the modulus. Further structural changes, resulting in variations in the viscoelastic response, were also induced through changes in salt concentration. The viscoelastic properties and the physical nature of the cross-links have important implications for the applicability of these gels as injectable drug delivery systems.

TI Influence of Bound Ion on the Morphology and Conductivity of Anion-Conducting Block Copolymers SO MACROMOLECULES LA English DT Article ID ALKALINE FUEL-CELLS; EXCHANGE MEMBRANES; PHASE-BEHAVIOR; LIQUIDS; TRANSPORT; MODEL AB Anion-conducting membranes are important for several applications including fuel cells and artificial photosynthesis. In this study such membranes were made by quaternizing polystyrene-block-polychloromethylstyrene (PS-b-PCMS) copolymers. PS-b-PCMS copolymers with molecular weights ranging from 4 to 60 kg/mol were synthesized by nitroxide-mediated controlled radical polymerization. Separate aliquots of the PS-b-PCMS samples were quaternized to transform the PCMS block. This resulted in block copolymers with ionizable blocks containing either trimethylammonium chloride or n-butylimidazolium chloride. We refer to ion-containing block copolymers synthesized from the same precursor as matched pairs: SAM (containing trimethylammonium chloride) and SIM (containing n-butylimidazolium chloride). The volume fraction of the ion-containing block, phi, ranges from 0.26 to 0.50 for the case of SAM and from 0.35 to 0.60 for the case of SIM. Self-assembly in these copolymers resulted in the formation of lamellar phases regardless of phi, chemical formula of the bound ion, and chain length. Chloride ion conductivity and water uptake measurements on one of the matched pairs led to similar results. Preliminary experiments wherein the chloride ions in this matched pair were replaced by hydroxide ions were performed, and the changes in conductivity due to this are reported.

TI Ionic Conduction in Nanostructured Membranes Based on Polymerized Protic Ionic Liquids SO MACROMOLECULES LA English DT Article ID BLOCK-COPOLYMER ELECTROLYTES; FUEL-CELLS; MECHANICAL-PROPERTIES; MOLECULAR-WEIGHT; METHANOL; PERFORMANCE AB Polymerized ionic-liquids (PILs) are promising materials whose ionic properties can be tuned based on their chemistry. By incorporating PILs into block copolymer (BCP) structures, it is possible to provide complementary functionality (i.e., structural stability) and transport tunability to ion-conducting materials. In this study, we describe the self-assembly and conductivity of novel poly(styrene-block-histamine methacrylamide) diblock copolymers (PS-b-PHMA) and the resulting PS-b-PIL derivatives obtained after treatment with trifluoroacetic acid (TFA). These materials self-assemble into ordered BCP structures with tunable domain sizes as demonstrated by small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM). PS-b-PHMA membranes show conductivities up to 2 x 10(-4) S/cm at room temperature, which increase by an order of magnitude in the presence of acid. In addition, both PHMA- and PIL-based membranes exhibit lower water uptake (lambda = 4-6 and 8-10, respectively) in comparison with most proton conducting membranes reported elsewhere. The low water content in these membranes translates into a stronger effect of morphology on transport behavior, resulting in a measurable increase in ion conductivity as a function of conducting channel size.

The performance of these materials depends on the protein structure and phase behavior arising from a balance between the enthalpic interactions of the components and surrounding media as well as the entropic contribution associated with polymer chain deformation. There is a great need to perform structural studies in solution that systematically investigate the polymer chain conformation upon linkage to a peptide or protein so as to evaluate how polymers affect the protein structure of the biomolecule and, consequently, its functionality. Combinations of a range of factors including low contrast, weak scattering signals in dilute solutions as well as difficulties in separating the component scattering contributions, pose significant challenges to structural characterization. Here we present a synchrotron small-angle X-ray scattering (SAXS) study of two model helix bundle forming peptide-polymer conjugates and show that with analytical modeling of the scattering intensity detailed structural information on both peptide structure and polymer conformation can be extracted. The peptide-poly(ethylene glycol) (PEG) conjugates are based on peptides that self-associate to form well-defined 3- or 4-helix bundles and the PEG chain is covalently linked either to the end or the side of the peptide (i.e. end- or side-conjugation). Using a simplified analytical geometrical body form factor model, where the peptide-polymer bundles are modeled as parallel cylinders with attached Gaussian chains, a quantitative description of the scattering behavior can be reached. On the basis of the simplified structural model, the protein tertiary structures, i.e., the alpha-helix bundle, remains largely intact and maintains its oligomeric state but exhibits slight swelling in solution with respect to the crystal structure. The PEG chain conformation appears to slightly depend on the conjugate architecture. In terms of the chain dimension represented by R-g, the end-conjugated PEG exhibit similar value as compared to free PEG for the molecular weight studied (2 kDa). For the side-conjugates our simple scattering model seems to indicate a systematically slightly lower values for R-g, i.e., a slight compression, in particular for the highest molecular weight (5 kDa). However, considering the limitations of the model and experimental uncertainties, further investigations, such as neutron scattering, is needed to illustrate detailed chain conformation. The present studies can be extended to other peptide-polymer or protein-polymer hybrid systems to extract information on both protein structure and polymer chain conformation. This work will thus provide valuable guidance to understand their structure and phase behavior using X-ray and neutron scattering.

The measurement of these processes can provide valuable information on nonlinear QCD phenomena, such as gluon saturation, and is the the only known way to gain insight into the spatial distribution of gluons in nuclei. We present predictions of differential cross-section distribution d sigma/dQ(2) and d sigma/dt for J/psi and phi meson production for diffractive processes of heavy nuclei, and demonstrate the feasibility of extracting the gluon source distribution of heavy nuclei, F(b), from coherent diffraction. We briefly introduce a new event generator based on our method that can be used for studying exclusive diffractive processes at a future electron-ion collider.

TI Ferromagnetic quantum critical point in UCo1-xFexGe SO PHYSICAL REVIEW B LA English DT Article ID SUPERCONDUCTIVITY; COEXISTENCE; DISORDER; UGE2; TEMPERATURE; TRANSITIONS; PRESSURE; SYSTEMS; LATTICE AB We have carried out a comprehensive study of the UCo1-xFexGe series across the entire range of compositions 0 <= x <= 1, and report the results of x-ray diffraction, magnetization, specific heat, and electrical resistivity measurements to uncover the T-x phase diagram. Substitution of Fe into UCoGe initially results in an increase in the Curie temperature and a rapid destruction of the superconductivity. Near x = 0.22, the ferromagnetic transition is suppressed to zero temperature at an apparent ferromagnetic itinerant electron quantum critical point, where the temperature dependence of the electrical resistivity and specific heat in this region reveal non-Fermi liquid behavior.

The calculations were benchmarked to obtain the correct semiconducting, Jahn-Teller distorted electronic ground state of bulk LiMn2O4 and, using the same parameters, the predominant low-index polar surface facets (100), (110), and (111) were calculated to study their structure and stability. Following an investigation of possible surface terminations as well as surface layer reconstructions we find that the (111) LMO surface stabilizes through a targeted site exchange of the undercoordinated surface Mn cations with fully coordinated tetrahedral subsurface Li cations, effectively creating a partial inverse spinel arrangement at the surface. This reconstruction renders the (111) facet the most stable among the investigated facets. The equilibrium (Wulff) shape of a LiMn2O4 particle was constructed and exhibits a cubo-octahedral shape with predominant (1 1 1) facets, in agreement with common experimental findings for the spinel structure.

We succeeded in probing the intrinsic interlayer response by performing infrared experiments on the crystals with a cleaved ac surface. Our experiments identify the coexistence of the suppression of the electronic spectral weight and the development of a coherent Drude-like response in the normal state. The formation of the interlayer condensate is clearly observed in the superconducting state and appears to be linked to coherent contribution to the normal-state conductivity.

TI Cooper Pairing Above the Critical Temperature in a Unitary Fermi Gas SO PHYSICAL REVIEW LETTERS LA English DT Article ID COHERENCE LENGTH SUPERCONDUCTORS; BEHAVIOR AB We present an ab initio determination of the spin response of the unitary Fermi gas. Based on finite temperature quantum Monte Carlo calculations and the Kubo linear-response formalism, we determine the temperature dependence of the spin susceptibility and the spin conductivity. We show that both quantities exhibit suppression above the critical temperature of the superfluid-to-normal phase transition due to Cooper pairing. The spin diffusion transport coefficient does not display a minimum in the vicinity of the critical temperature and drops to very low values D-s approximate to 0:8 (h) over bar /m in the superfluid phase. All these spin observables show a smooth and monotonic behavior with temperature when crossing the critical temperature T-c, until the Fermi liquid regime is attained at the temperature T-*, above which the pseudogap regime disappears.

TI beta-Delayed Neutron Spectroscopy Using Trapped Radioactive Ions SO PHYSICAL REVIEW LETTERS LA English DT Article ID R-PROCESS NUCLEOSYNTHESIS; DETECTION EFFICIENCY; MICROCHANNEL-PLATE; ENERGY-SPECTRA; GAS CATCHERS; DECAY; NUCLEI; I-137; STABILITY; EMISSION AB A novel technique for beta-delayed neutron spectroscopy has been demonstrated using trapped ions. The neutron-energy spectrum is reconstructed by measuring the time of flight of the nuclear recoil following neutron emission, thereby avoiding all the challenges associated with neutron detection, such as backgrounds from scattered neutrons and gamma rays and complicated detector-response functions. I-137(+) ions delivered from a Cf-252 source were confined in a linear Paul trap surrounded by radiation detectors, and the beta-delayed neutron-energy spectrum and branching ratio were determined by detecting the beta- and recoil ions in coincidence. Systematic effects were explored by determining the branching ratio three ways. Improvements to achieve higher detection efficiency, better energy resolution, and a lower neutronenergy threshold are proposed. DOI: 10.1103/PhysRevLett.110.092501 C1 [Yee, R. M.; Scielzo, N.

Based on known zonation patterns in protein, glucose and lipid metabolism, coupled with evidence that phosphatidylcholine may play a role in NASH pathogenesis, we hypothesized that phospholipid zonation exists in liver and that specific phospholipid abundance and distribution may be associated with histologic disease. A survey of normal hepatic protein expression profiles in the Human Protein Atlas revealed pronounced zonation of enzymes involved in lipid utilization and storage, particularly those facilitating phosphatidylcholine (PC) metabolism. Immunohistochemistry of obese normal, SS and NASH liver specimens with anti-phosphatidylethanomine N-methyltransferase (PEMT) antibodies showed a progressive decrease in the zonal distribution of this PC biosynthetic enzyme. Phospholipid quantitation by liquid chromatography mass spectrometry (LC-MS) in hepatic extracts of Class III obese patients with increasing NAFLD severity revealed that most PC species with 32, 34 and 36 carbons as well as total PC abundance was decreased with SS and NASH. Matrix assisted laser desorption ionization - imaging mass spectrometry (MALDI-IMS) imaging revealed strong zonal distributions for 32, 34 and 36 carbon PCs in controls (minimal histologic findings) and SS that was lost in NASH specimens. Specific lipid species such as PC 34: 1 and PC 36: 2 best illustrated this phenomenon. These findings suggest that phospholipid zonation may be associated with the presence of an intrahepatic proinflammatory phenotype and thus have broad implications in the etiopathogenesis of NASH.

Recently, Yamanoi et al. (2012, AJ, 144, 40) suggested the existence of a discrepancy between the SDF and SXDS catalogs. We have used the Sloan Digital Sky Survey (SDSS) Data Release 8 (DR8) catalog and compared stars in common between SDF/SXDS and SDSS. We confirmed that there exists a 0.12 mag offset in the B-band between the SDF and SXDS catalogs. Moreover, we found that significant zero-point offsets in the i-band (similar to 0.10 mag) and the z-band (similar to 0.14 mag) need to be introduced to the SDF/SXDS catalogs to make it consistent with the SDSS catalog. We report the measured zero point offsets of five filter bands of SDF/SXDS catalogs. We studied the potential cause of these offsets, but the origins are yet to be understood.

TI Rectified diode response of a multimode quantum cascade laser integrated terahertz transceiver SO OPTICS EXPRESS LA English DT Article ID SCHOTTKY-BARRIER DIODES; HETERODYNE RECEIVER; LOCKING; MIXERS AB We characterized the DC transport response of a diode embedded in a THz quantum cascade laser as the laser current was changed. The overall response is described by parallel contributions from the rectification of the laser field due to the non-linearity of the diode I-V and from thermally activated transport. Sudden jumps in the diode response when the laser changes from single mode to multi-mode operation, with no corresponding jumps in output power, suggest that the coupling between the diode and laser field depends on the spatial distribution of internal fields. The results demonstrate conclusively that the internal laser field couples directly to the integrated diode.

TI Substrate-modified scattering properties of silicon nanostructures for solar energy applications SO OPTICS EXPRESS LA English DT Article ID FANO RESONANCES; GOLD NANORODS; NANOPARTICLES; PARTICLES; DIPOLE; ANTENNAS AB Enhanced light trapping is an attractive technique for improving the efficiency of thin film silicon solar cells. In this paper, we use FDTD simulations to study the scattering properties of silicon nanostructures on a silicon substrate and their application as enhanced light trappers. We find that the scattered spectrum and angular scattering distribution strongly depend on the excitation direction, that is, from air to substrate or from substrate to air. At the dipole resonance wavelength the scattering angles tend to be very narrow compared to those of silicon nanostructures in the absence of a substrate. Based on these properties, we propose a new thin film silicon solar cell design incorporating silicon nanostructures on both the front and back surfaces for enhanced light trapping.

The results indicate this change is related to the formation of color centers in the material as well as the generation of a transient defect population during exposure to the laser pulses.

In analogy with surface plasmons supported in metals, we observe that, in a photonic crystal metamaterial, the electromagnetic surface waves arise from a negative effective permittivity. The proposed device is dimensioned in order to support surface states in a large spectral window (similar or equal to 1550-1650 nm). The result opens strategies in light control at the nanoscale, allowing on chip light manipulation in a wide frequency range and avoiding the intrinsic limits of plasmonic structures due to absorption losses in metals.

It had been proposed that impurity doping of TlBr can suppress the ionic conductivity because the impurities can getter vacancies to form neutral complexes. This paper shows that the isolated vacancies can maintain their equilibrium concentrations even at room temperature, rendering any gettering methods ineffective. The main effect of doping is to change the Fermi level and consequently the vacancy concentration. The minimal ionic conductivity is reached at the donor concentration of [D+] = 4 x 10(16) cm(-3).

TI Influence of interfacial properties on thermal transport at gold:silicon contacts SO APPLIED PHYSICS LETTERS LA English DT Article ID PHONON TRANSPORT; HEAT-TRANSPORT; CONDUCTANCE; CONDUCTIVITY; THERMOREFLECTANCE; TEMPERATURES; NANOSCALE; SOLIDS; FILMS; FLOW AB We measure the Kapitza conductances at Au:Si contacts from 100 to 296 K via time-domain thermoreflectance. Contacts are fabricated by evaporating Au films onto Si substrates. Prior to Au deposition, the Si substrates receive pretreatments in order to modify interfacial properties, i.e., bonding and structural disorder. Through the inclusion of a Ti adhesion layer and the removal of the native oxide, Kapitza conductance can be enhanced by a factor of four at 296 K. Furthermore, interfacial roughness is found to have a negligible effect, which we attribute to the already low conductances of poorly bonded Au:Si contacts. (C) 2013 American Institute of Physics.

TI Strain-driven broken twin boundary coherence in YBa2Cu3O7-delta nanocomposite thin films SO APPLIED PHYSICS LETTERS LA English DT Article ID CRITICAL CURRENTS; SUPERCONDUCTING WIRES; BICRYSTALS; DEFECTS; GROWTH AB In this letter we use high resolution scanning transmission electron microscopy to study epitaxial YBa2Cu3O7-delta (YBCO) nanocomposite thin films. We find that twin boundaries (TB) in YBCO nanocomposite thin films are disturbed by the presence of secondary phase nanoparticles as well as by intergrowths. Secondary phases promote the nucleation of TBs and, at the same time, result in bending, decreasing and changing the TB's spacing. On the other hand, the local strain ensuing from the partial dislocation associated to Y248 and Y125 intergrowths break the vertical coherence of TBs. This interaction results in a complex domain structure where twin boundary coherence is no longer satisfied and twin spacing is reduced down to a few nanometers precluding vortex channeling at low temperatures.

TI Effect of stoichiometry on the dielectric properties and soft mode behavior of strained epitaxial SrTiO3 thin films on DyScO3 substrates SO APPLIED PHYSICS LETTERS LA English DT Article ID STRUCTURAL PHASE-TRANSITIONS; STRONTIUM-TITANATE; SPECTROSCOPY; RELAXOR; FERROELECTRICITY; PEROVSKITES; BATIO3; OXIDES AB The effect of stoichiometry on the dielectric properties and soft mode behavior of strained epitaxial Sr1+xTiO3+delta films grown on DyScO3 substrates is reported. Direct comparisons between nominally stoichiometric and non-stoichiometric films have been performed through measurements of lattice parameters, temperature-dependent permittivities, second harmonic generation, and terahertz dielectric spectra. The nominally stoichiometric film shows dispersion-free low-frequency permittivity with a sharp maximum and pronounced soft mode behavior. Our results suggest that strained perfectly stoichiometric SrTiO3 films should not show relaxor behavior and that relaxor behavior emerges from defect dipoles that arise from non-stoichiometry in the highly polarizable strained SrTiO3 matrix.

In this work, cerium oxide thin films were grown onto silicon substrates under different O-2 flow rates, which were varied from 20 to 80% of the total flow rate with simultaneous changes in the Ar flow rate. In addition, different growth conditions and the influence of post-deposition rapid thermal annealing (RTA) were performed to tailor the stoichiometry of the cerium oxide films. The microstructure and mechanical properties of the films were characterized using electron probe microanalysis (EPMA), X-ray diffraction, field-emission scanning electron microscopy, X-ray photoelectron spectroscopy, and nano-indentation. EPMA results revealed that all as-deposited CeO2-x films have an O/Ce ratio about 1.75. When the post-annealing temperature (T-PA) for the films was increased from 800 to 1100 degrees C, a reduction of oxygen in the film was observed, which led to a phase transition from cubic CeO2-x (111) to hexagonal Ce2O3 (002). This phase transition is related to Ce4+ to Ce2+ cation transformation due to the formation of oxygen vacancies. The hardness and elastic modulus of the as-deposited CeO2-x films were 11.7 GPa and 241 GPa, respectively, which were reduced to about 7.5 GPa and 150 GPa, respectively, after annealing at 1100 degrees C.

TI Carbon turnover in the water-soluble protein of the adult human lens SO MOLECULAR VISION LA English DT Article ID BOMB C-14 DATA; NUCLEAR CATARACT; VERTEBRATE LENS; AGE CALIBRATION; CELL TURNOVER; GAP-JUNCTIONS; OCULAR LENS; FIBER CELLS; RADIOCARBON; CRYSTALLINS AB Purpose: Human eye lenses contain cells that persist from embryonic development. These unique, highly specialized fiber cells located at the core (nucleus) of the lens undergo pseudo-apoptosis to become devoid of cell nuclei and most organelles. Ostensibly lacking in protein transcriptional capabilities, it is currently believed that these nuclear fiber cells owe their extreme longevity to the perseverance of highly stable and densely packed crystallin proteins. Maintaining the structural and functional integrity of lenticular proteins is necessary to sustain cellular transparency and proper vision, yet the means by which the lens actually copes with a lifetime of oxidative stress, seemingly without any capacity for protein turnover and repair, is not completely understood. Although many years of research have been predicated upon the assumption that there is no protein turnover or renewal in nuclear fiber cells, we investigated whether or not different protein fractions possess protein of different ages by using the C-14 bomb pulse. Methods: Adult human lenses were concentrically dissected by gently removing the cell layers in water or shaving to the nucleus with a curved micrometer-controlled blade. The cells were lysed, and the proteins were separated into water-soluble and water-insoluble fractions. The small molecules were removed using 3 kDa spin filters. The C-14/C was measured in paired protein fractions by accelerator mass spectrometry, and an average age for the material within the sample was assigned using the C-14 bomb pulse. Results: The water-insoluble fractions possessed C-14/C ratios consistent with the age of the cells. In all cases, the water-soluble fractions contained carbon that was younger than the paired water-insoluble fraction. Conclusions: As the first direct evidence of carbon turnover in protein from adult human nuclear fiber cells, this discovery supports the emerging view of the lens nucleus as a dynamic system capable of maintaining homeostasis in part due to intricate protein transport mechanisms and possibly protein repair. This finding implies that the lens plays an active role in the aversion of age-related nuclear (ARN) cataract.

TI Structural phase transitions and electronic phenomena at 180-degree domain walls in rhombohedral BaTiO3 SO PHYSICAL REVIEW B LA English DT Article ID FERROELECTRIC THIN-FILMS; CONDUCTION; FLEXOELECTRICITY; DIAGRAMS; BIFEO3 AB The structure and electronic phenomena at the 180-degree domain wall in the rhombohedral phase of BaTiO3 are described using Landau-Ginzburg-Devonshire theory. Dependent on the wall orientation, two types of domain wall behaviors are identified. The low-energy "achiral" phase occurs in the vicinity of the {110} orientation and has odd polarization profile invariant with respect to inversion about the wall center. The "chiral" phase occurs around {211} wall orientations and corresponds to mixed parity domain walls. The temperature-induced transformation between the phases is abrupt and is accompanied with 20%-30% change of the domain wall thickness. This process gives rise to the significant changes of the electronic structure of the wall. Depending on the temperature and flexoelectric coupling strength, relative conductivity of the wall becomes at least one order of magnitude higher than in the single-domain region. The possible strategies for exploring these transitions based on direct measurements of domain wall width and conductive atomic force microscopy are discussed.

Its application to this end, however, has been hampered by degradation of performance over time, in a process called polarization. This effect has been traditionally assigned to a build-up of ions at the electrodes, which would counteract an applied electrical bias field. Here, we estimate the ionic mobility in TlBr and its possible association with the polarization effect using parameter-free quantum simulations. Our results indicate that in samples with up to moderate levels of impurities, ions cannot traverse distances large enough to generate zones of accumulation and depletion in the crystal, suggesting different causes for the polarization effect.

These devices, although early in their stage of development, are promising for large-scale grid storage applications due to the abundance and very low cost of sodium-containing precursors used to make the components. The engineering knowledge developed recently for highly successful Li ion batteries can be leveraged to ensure rapid progress in this area, although different electrode materials and electrolytes will be required for dual intercalation systems based on sodium. In particular, new anode materials need to be identified, since the graphite anode, commonly used in lithium systems, does not intercalate sodium to any appreciable extent. A wider array of choices is available for cathodes, including high performance layered transition metal oxides and polyanionic compounds. Recent developments in electrodes are encouraging, but a great deal of research is necessary, particularly in new electrolytes, and the understanding of the SEI films. The engineering modeling calculations of Na-ion battery energy density indicate that 210 Wh kg1 in gravimetric energy is possible for Na-ion batteries compared to existing Li-ion technology if a cathode capacity of 200 mAh g1 and a 500 mAh g1 anode can be discovered with an average cell potential of 3.3 V.

High capacity and energy density are readily achievable using Ni-rich Li[Ni1-xMx]O2 (x = 0.10.2, M = Ni, Co, Mn, and Al) cathodes. Unfortunately, their structural instability is associated with severe capacity fading on cycling, which hinders practical applications. Here, a method is presented for producing a continuous compositional change between Li[Ni0.8Co0.2]O2 (center) and Li[Ni0.8Co0.01Mn0.19]O2 (surface) in a spherical particle, resulting in an average composition of Li[Ni0.8Co0.06Mn0.14]O2. The chemical composition in the particle is gradually altered by decreasing the Co concentration while adding Mn content. The Ni content remains fixed. Coin cells with the solid-solution cathode deliver a specific capacity over 210 mAh g1 in the voltage range of 2.74.3 V vs. Li/Li+ with capacity retention of 85% over 100 cycles at 25 and 55 degrees C. The main exothermic temperature upon heating appears at around 250 degrees C with relatively low heat generation (810 J g1). The presence of the tetravalent Mn at the particle surface is mainly responsible for the high capacity upon cycling and excellent thermal properties.

Systematic studies, using combined well-defined in situ techniques, are crucial to obtaining in-depth understanding of the structural origin of this thermal instability in overcharged cathode materials. Here time-resolved X-ray diffraction, X-ray absorption, mass spectroscopy, and high-resolution transmission electron microscopy during heating are combined to detail the structural changes in overcharged LixNi0.8Co0.15Al0.05O2 and LixNi1/3Co1/3Mn1/3O2 cathode materials. By employing these several techniques in concert, various aspects of the structural changes are investigated in these two materials at an overcharged state; these include differences in phase-distribution after overcharge, phase nucleation and propagation during heating, the preferred atomic sites and migration paths of Ni, Co, and Mn, and their individual contributions to thermal stability, together with measuring the oxygen release that accompanies these structural changes. These results provide valuable guidance for developing new cathode materials with improved safety characteristics.

Here, a novel additive, phosphorus pentasulfide (P2S5) in organic electrolyte, is reported to boost the cycling performance of Li-S batteries. The function of the additive is two-fold: 1) P2S5 promotes the dissolution of Li2S and alleviates the loss of capacity caused by the precipitation of Li2S and 2) P2S5 passivates the surface of lithium metal and therefore eliminates the polysulfide shuttle phenomenon. A Li-S test cell demonstrates a high reversible capacity of 9001350 mAh g1 and a high coulombic efficiency of 90% for at least 40 stable cycles at 0.1 C.

Nanoarchitecture hydroxide precursor for these cathodes with two levels of particle agglomeration (12 m and 10 m) is produced using a co-precipitation method. Transmission electron microscopy and X-ray diffraction confirm that the precursor is a composite comprising transition metal hydroxides and Mn3O4. Cathode materials synthesized based on the precursor are layered (R$ \bar 3 $m)-layered (C2/m)-spinel (Fd$ \bar 3 $m) composite phase. The electrochemical performance of lithium cells utilizing this material as the cathode is determined to be excellent. Both the layered-layered-spinel composite structure and the nanoarchitecture morphology contribute to the electrochemical performance advantage of this material over other cathode materials.

TI Unexpected phase locking of magnetic fluctuations in the multi-k magnet USb SO PHYSICAL REVIEW B LA English DT Article ID TRANSPORT-PROPERTIES AB The spin waves in the multi-k antiferromagnet USb soften and become quasielastic well below the antiferromagnetic ordering temperature T-N. This occurs without a magnetic or structural transition. It has been suggested that this change is in fact due to dephasing of the different multi-k components: a switch from 3-k to 1-k behavior. In this work, we use inelastic neutron scattering with tridirectional polarization analysis to probe the quasielastic magnetic excitations and reveal that the 3-k structure does not dephase. More surprisingly, the paramagnetic correlations also maintain the same clear phase correlations well above T-N ( up to at least 1.4T(N)). DOI: 10.1103/PhysRevB.87.064421 C1 [Lim, J.

TI Effect of pressure, temperature, fluorine doping, and rare earth elements on the phonon density of states of LFeAsO studied by nuclear inelastic scattering SO PHYSICAL REVIEW B LA English DT Article ID IRON; DYNAMICS; SUPERCONDUCTIVITY; COMPRESSIBILITY; SPECTROSCOPY; SMFEASO AB We have performed systematic studies of the lattice dynamics in LFeAsO (L = La, Ce, Pr, Nd, Sm) in the parent and in the similar to 10% F-doped compounds as a function of pressure and temperature. We have found that the modifications in the partial Fe density of phonon states are mainly governed by the Fe-As bond length. The change of this bond length explains the change of the Fe density of phonon states above 25 meV. We further observe anomalies in the behavior of the phonon mode near 16 meV. In the parent phase, this mode softens anomalously upon cooling through the structural phase transition. Upon F doping, this mode hardens indicating a strong electron-phonon coupling. This suggests that the corresponding phonons play an important role in the competition between superconductivity and magnetism in these materials.

TI Evolution of superconducting correlations within magnetic-field-decoupled La2-xBaxCuO4 (x=0.095) SO PHYSICAL REVIEW B LA English DT Article ID HIGH-TEMPERATURE SUPERCONDUCTOR; T-C SUPERCONDUCTORS; II SUPERCONDUCTORS; PHASE-TRANSITIONS; 2-DIMENSIONAL SUPERCONDUCTORS; LAYERED SUPERCONDUCTOR; RESISTIVE TRANSITION; THERMAL FLUCTUATIONS; TRANSPORT-PROPERTIES; BI2SR2CACU2O8+DELTA AB We explore the evolution of superconductivity in La2-xBaxCuO4 with x = 0.095 in magnetic fields of up to 35 T applied perpendicular to the CuO2 planes. Previous work on this material has shown that perpendicular fields enhance both charge- and spin-stripe order within the planes. We present measurements of the resistivity parallel and perpendicular to the planes, as well as the Hall effect. Measurements of magnetic susceptibility for fields of up to 15 T applied both parallel and perpendicular to the planes provide complementary measures of the superconductivity. We showthat fields sufficient to destroy pair tunneling between the planes do not disrupt the superconducting correlations within the planes. In fact, we observe an onset of large-amplitude but phase-disordered superconductivity within the planes at approximately 30 K that is remarkably insensitive to field. With further cooling, we observe a phase-transition-like drop in the in-plane resistivity to an apparent state of superconductivity despite the lack of phase coherence between the layers. These observations raise interesting questions concerning the identification of the upper critical field, where pairing is destroyed, in underdoped cuprates.

TI Long-range order and spin-liquid states of polycrystalline Tb2+xTi2-xO7+y SO PHYSICAL REVIEW B LA English DT Article ID PYROCHLORE ANTIFERROMAGNET TB2TI2O7; MAGNETS AB Low-temperature states of polycrystalline samples of a frustrated pyrochlore oxide Tb2+x Ti2-x O7+y have been investigated by specific heat, magnetic susceptibility, and neutron scattering experiments. We have found that this system can be tuned by a minute change of x from a spin-liquid state (x < x(c)) to a partly ordered state with a small antiferromagnetic ordering of the order of 0.1 mu(B). Specific heat shows a sharp peak at a phase transition at T-c = 0.5 K for x = 0.005. Magnetic excitation spectra for this sample change from a quasielastic to a gapped type through T-c. The possibility of a Jahn-Teller transition is discussed.

TI Considerations for surface reconstruction stability prediction on GaAs(001) SO PHYSICAL REVIEW B LA English DT Article ID MOLECULAR-BEAM EPITAXY; GAAS; GROWTH AB We present a theoretical analysis of the finite-temperature equilibrium surface reconstruction stability of GaAs(001) from first principles, encompassing the As-rich regime relevant to low-temperature grown GaAs. Experimental evidence points to the thermodynamic stability of a (4 x 3) reconstruction in this regime, but density functional theory (DFT) calculations predict all (4 x 3) reconstructions to be metastable relative to the beta 2(2 x 4) and c(4 x 4) reconstructions. We employ statistical mechanical simulations, parameterized by DFT to study the combined effects of configurational disorder and vibrational excitations on surface phase stability. The calculated finite-temperature surface free energies of the various reconstructions indicate that, if a small constant energy shift is used to enforce stability of the lowest-energy (4 x 3), the resultant phase diagram is consistent with experiment with the c(4 x 4) overwhelming (4 x 3) at high temperatures. This behavior is due to competition between configurational entropy, which favors c(4 x 4), and vibrational entropy, which favors (4 x 3).

TI Colloidal lattice shearing and rupturing with a driven line of particles SO PHYSICAL REVIEW E LA English DT Article ID CHARGE-DENSITY WAVES; DYNAMICS; SUPERCONDUCTORS; VORTICES; INTRUDER AB We examine the dynamics of two-dimensional colloidal systems using numerical simulations of a system with a drive applied to a thin region in the middle of the sample to produce a local shear. For a monodisperse colloidal assembly, we find a well-defined decoupling transition separating a regime of elastic motion from a plastic phase where the driven particles break away or decouple from the bulk particles and produce a shear band. For a bidisperse assembly, the onset of a bulk disordering transition coincides with the broadening of the shear band. We identify several distinct dynamical regimes that are correlated with features in the velocity-force curves. As a function of bidispersity, the decoupling force shows a nonmonotonic behavior associated with features in the noise fluctuations, power spectra, and bulk velocity profiles. When pinning is added in the bulk, we find that the shear band regions can become more localized, causing a decoupling of the driven particles from the bulk particles. For a system with thermal noise and no pinning, the shear band region becomes more extended and the average velocity of the driven particles drops at the thermal disordering transition of the bulk system.

Several of these potential waste streams contain elevated levels of transition metal elements such as molybdenum (Mo). Molybdenum has limited solubility in typical silicate glasses used for nuclear waste immobilization. Under certain chemical and controlled cooling conditions, a powellite (Ba,Ca)MoO4 crystalline structure can be formed by reaction with alkaline earth elements. In this study, single phase BaMoO4 and CaMoO4 were formed from carbonate and oxide precursors demonstrating the viability of Mo incorporation into glass, crystalline or glass composite materials by a melt and crystallization process. X-ray diffraction, photoluminescence, and Raman spectroscopy indicated a long range ordered crystalline structure. In situ electron irradiation studies indicated that both CaMoO4 and BaMoO4 powellite phases exhibit radiation stability up to 1000 years at anticipated doses with a crystalline to amorphous transition observed after 1 x 10(13) Gy. Aqueous durability determined from product consistency tests (PCT) showed low normalized release rates for Ba, Ca, and Mo (<0.05 g/m(2)). (C) 2012 Elsevier B.V. All rights reserved.

TI Copper ionic liquids: Examining the role of the anion in determining physical and electrochemical properties SO INORGANICA CHIMICA ACTA LA English DT Article DE Ionic liquids; Crystal structure; Copper; Electrochemistry ID CATALYTIC REACTIONS; ELECTRODEPOSITION; COMPLEXES; SOLVENTS; CATIONS AB Five new copper(II)-based ionic liquids and three crystalline compounds have been synthesized in order to further understand the role of the anion in determining their physicochemical properties. Materials were prepared with combinations of three different anions (2-ethylhexanoate (EHN), tetrafluoroborate (BF4), and triflate (OTf)) and six-coordinate Cu(II) cations. The complexes that contain at least one BF4 anion consistently displayed both the highest specific conductivity and electrochemical reversibility. The presence of one OTf anion (in combination with one EHN or BF4) facilitates the formation of crystalline materials. Single crystal X-ray diffraction studies were completed on two of the mixed anion compounds. The results show that both ethanolamine (EA) and diethanolamine (DEA) chelate to the Cu(II) centers in a highly distorted tetragonal geometry. The properties of the ionic liquid with the overall lowest viscosity and highest conductivity and electrochemical reversibility (Cu{NH2CH2CH2OH}(6)(BF4)(2), 4) were studied as a function of temperature. The viscosity decreases with increasing temperature, but at 45 degrees C (over three hours) there is a loss of two EA ligands to form a more viscous four-coordinate complex. Cyclic voltammetry of 4 reveals a quasi-reversible Cu(II)/Cu(I) reduction wave that shifts to more positive potentials with increasing temperature. (C) 2012 Elsevier B.V. All rights reserved.

Here, H. irregulare was grown on biomass, and the most abundant protein in the culture filtrate was identified as the only family 7 glycoside hydrolase in the genome, which consists of a single catalytic domain, lacking a linker and carbohydrate-binding module. The enzyme, HirCel7A, was characterized biochemically to determine the optimal conditions for activity. HirCel7A was crystallized and the structure, refined at 1.7 angstrom resolution, confirms that HirCel7A is a cellobiohydrolase rather than an endoglucanase, with a cellulose-binding tunnel that is more closed than Phanerochaete chrysosporium Cel7D and more open than Hypocrea jecorina Cel7A, suggesting intermediate enzyme properties. Molecular simulations were conducted to ascertain differences in enzyme-ligand interactions, ligand solvation, and loop flexibility between the family 7 glycoside hydrolase cellobiohydrolases from H. irregulare, H. jecorina, and P. chrysosporium. The structural comparisons and simulations suggest significant differences in enzyme-ligand interactions at the tunnel entrance in the -7 to -4 binding sites and suggest that a tyrosine residue at the tunnel entrance of HirCel7A may serve as an additional ligand-binding site. Additionally, the loops over the active site in H. jecorina Cel7A are more closed than loops in the other two enzymes, which has implications for the degree of processivity, endo- initiation, and substrate dissociation. Overall, this study highlights molecular level features important to understanding this biologically and industrially important family of glycoside hydrolases.

TI Influence of monolayer contamination on electric-field-noise heating in ion traps SO PHYSICAL REVIEW A LA English DT Article ID AUGMENTED-WAVE METHOD; ENERGY; GOLD AB Electric field noise is a hinderance to the assembly of large-scale quantum computers based on entangled trapped ions. Apart from ubiquitous technical noise, experimental studies of trapped ion heating have revealed additional limiting contributions to this noise, originating from atomic processes on the electrode surfaces. In a recent work [Safavi-Naini, Rabl, Weck, and Sadeghpour, Phys. Rev. A 84, 023412 (2011)] we described a microscopic model for this excess electric field noise, which points away towards a more systematic understanding of surface adsorbates as progenitors of electric field jitter noise. Here, we address the impact of surface monolayer contamination on adsorbate-induced noise processes. Using exact numerical calculations for H and N atomic monolayers on a Au(111) surface, representing opposite extremes of physisorption and chemisorption, we show that an additional monolayer can significantly affect the noise power spectrum and, respectively, enhance and suppress the heating rates.

TI Evidence for an internal-field-induced spin-flop configuration in the extended kagome YBaCo4O7 SO PHYSICAL REVIEW B LA English DT Article ID RELAXATION; DYNAMICS AB The spin structure and spin dynamics in the extended kagome frustrated antiferromagnet YBaCo4O7 have been investigated using zero field and low applied field Co-59 NMR. The YBaCo4O7 lattice is made up of bipyramid Co-ion units that form alternating planes of edge-sharing spin triangles and corner-sharing kagome spin triangles in an unusual exchange topology. Our low-temperature spin configuration results, based on hyperfine field orientations, are consistent with those from neutron scattering for the triangle spins which order antiferromagnetically below 106 K. For the kagome spins at low temperatures the static hyperfine fields are found to be oriented orthogonal to those of the triangle spins in a spin-flop configuration that is in disagreement with the neutron findings. Nuclear relaxation rate measurements made as a function of temperature show that inhomogeneous dynamic spin disorder occurs in kagome planes well below the Neel point.

Near theKitaev limit, p-wave superconducting states which break the time-reversal symmetry are stabilized as reported by You et al. [Phys. Rev. B 86, 085145 (2012)] irrespective of the sign of the Kitaev interaction. By further doping, a d-wave superconducting state appears when the Kitaev interaction is antiferromagnetic, while another p-wave superconducting state appears when the Kitaev interaction is ferromagnetic. This p-wave superconducting state does not break the time-reversal symmetry as reported by Hyart et al. [Phys. Rev. B 85, 140510 (2012)], and such a superconducting state also appears when the antiferromagnetic Kitaev interaction and the ferromagnetic Heisenberg interaction compete. This work, thus, demonstrates the clear difference between the antiferromagnetic Kitaev model and the ferromagnetic Kitaev model when carriers are doped while these models are equivalent in the undoped limit, and how novel superconducting states emerge when the Kitaev interaction and the Heisenberg interaction compete.

We find that in the corresponding kinematic region the spin asymmetry calculated in the small-x approach is consistent with either the usual transverse-momentum-dependent factorization formalism or the collinear factorization formalism, respectively. We estimate the Sivers asymmetry for both polarized p + p and p + A collisions and argue that the Drell-Yan production is an interesting and unique probe for both the transverse spin physics and the small-x saturation effect.

Reichhardt, C. TI Rheology and shear band suppression in particle and chain mixtures SO PHYSICAL REVIEW E LA English DT Article ID TEMPERATURE; POLYMERS; STRESS; RATES AB Using numerical simulations we consider an amorphous particle mixture which exhibits shear localization, and find that the addition of even a small fraction of chains strongly enhances the material strength, creating pronounced overshoot features in the stress-strain curves. The strengthening occurs in the case where the chains are initially perpendicular to the shear direction, leading to a suppression of the shear band. This also leads to stiffening effects that are typical of polymeric systems. For large strain, the chains migrate to the region where a shear band forms, resulting in a stress drop. For chains larger than the linear system size we find oscillatory behavior, which does not resemble polymeric systems since the second stress peak is larger than the first. Our results are also useful for providing insights into methods of controlling and strengthening granular materials against failure.

TI A nanoscale co-precipitation approach for property enhancement of Fe-base alloys SO SCIENTIFIC REPORTS LA English DT Article ID ATOM-PROBE; MICROSTRUCTURAL EVOLUTION; COPPER PRECIPITATION; ELECTRON-MICROSCOPY; TEMPORAL EVOLUTION; FERRITIC STEEL; CU; IRRADIATION AB Precipitate size and number density are two key factors for tailoring the mechanical behavior of nanoscale precipitate-hardened alloys. However, during thermal aging, the precipitate size and number density change, leading to either poor strength or high strength but significantly reduced ductility. Here we demonstrate, by producing nanoscale co-precipitates in composition-optimized multicomponent precipitation-hardened alloys, a unique approach to improve the stability of the alloy against thermal aging and hence the mechanical properties. Our study provides compelling experimental evidence that these nanoscale co-precipitates consist of a Cu-enriched bcc core partially encased by a B2-ordered Ni( Mn, Al) phase. This co-precipitate provides a more complex obstacle for dislocation movement due to atomic ordering together with interphases, resulting in a high yield strength alloy without sacrificing alloy ductility.

Molecular dynamics (MD) simulations claim many successes in forecasting the phenomena. The transitions are also studied in the framework of thermodynamics based methods and minimalistic models. In here, the proposed approach is derived in the framework of continuum and includes spatial and temporal dynamic heterogeneities; the approach is meant to capture the material behavior at small scales. We conjecture that the liquid-like and solid-like behaviors are dissimilar enough for the two to be governed by different constitutive relations. In this way, we gain additional degree of freedom, which is found essential when predicting the transitional phenomena. As a result, we derive the LLST criteria for liquids in equilibrium, during steady flow and at transient conditions. Lastly, we forecast short-lived LLSTs in human blood during cardiac cycle.

TI Transfer matrix computation of critical polynomials for two-dimensional Potts models SO JOURNAL OF PHYSICS A-MATHEMATICAL AND THEORETICAL LA English DT Article ID PARTITION-FUNCTION ZEROS; ANTIFERROMAGNETIC TRANSITION; CRITICAL-BEHAVIOR; LATTICE; PERCOLATION; TRANSFORMATION; TEMPERATURE; PHASE AB In our previous work [1] we have shown that critical manifolds of the q-state Potts model can be studied by means of a graph polynomial P-B(q, v), henceforth referred to as the critical polynomial. This polynomial may be defined on any periodic two-dimensional lattice. It depends on a finite subgraph B, called the basis, and the manner in which B is tiled to construct the lattice. The real roots v = e(K) - 1 of P-B(q, v) either give the exact critical points for the lattice, or provide approximations that, in principle, can be made arbitrarily accurate by increasing the size of B in an appropriate way. In earlier work, P-B(q, v) was defined by a contraction-deletion identity, similar to that satisfied by the Tutte polynomial. Here, we give a probabilistic definition of P-B(q, v), which facilitates its computation, using the transfer matrix, on much larger B than was previously possible. We present results for the critical polynomial on the (4, 8(2)), kagome, and (3, 12(2)) lattices for bases of up to respectively 96, 162, and 243 edges, compared to the limit of 36 edges with contraction-deletion. We discuss in detail the role of the symmetries and the embedding of B. The critical temperatures v(c) obtained for ferromagnetic (v > 0) Potts models are at least as precise as the best available results from Monte Carlo simulations or series expansions. For instance, with q = 3 we obtain v(c)(4, 8(2)) = 3.742 489 (4), v(c)(kagome) = 1.876 459 7 (2), and v(c)(3, 12(2)) = 5.033 078 49 (4), the precision being comparable or superior to the best simulation results. More generally, we trace the critical manifolds in the real (q, v) plane and discuss the intricate structure of the phase diagram in the antiferromagnetic (v < 0) region.

TI Proteome coverage of the model plant Arabidopsis thaliana: Implications for shotgun proteomic studies SO JOURNAL OF PROTEOMICS LA English DT Article DE Arabidopsis; Database; Coverage ID MASS-SPECTROMETRY DATA; IDENTIFICATION; DATABASE; INFORMATION; PROTEINS; SEQUENCE; RESOURCE; TOOL AB The recent aggregation of matched proteomics data for the model plant Arabidopsis has enabled the assessment of a diverse array of large scale shotgun proteomics data. A collection of over nine million matched peptides was used to assess proteome coverage and experimental parameters when compared to the theoretical tryptic peptide population. The analysis indicated that the experimentally identified median peptide mass was significantly higher than the theoretical median tryptic peptide in Arabidopsis. This finding led to a critical examination of precursor scan ranges currently being employed by shotgun proteomic studies. The analysis revealed diminishing returns at the high end scan range and opportunities for greater coverage and identifications at the low mass range. Based on these findings, a recommended basic scan range of 300 to 1200 m/z would suitably capture the peptide population in shotgun proteomic analyses in Arabidopsis. (C) 2013 Elsevier B.V.

We show that for the (10, 0) carbon nanotube, doping can significantly reduce quasiparticle band gaps and exciton binding energies. Remarkably, these two effects cancel to a large extent in the optical absorption spectra, resulting in small energy shifts of the prominent optical peaks. While the nature of these peaks remains a bound exciton, their intensity can be much decreased upon doping. By solving the effective mass equation for excitons over a wide range of doping levels, we demonstrate the tunability of the exciton binding energy in the high doping regime, which is shown to follow a mild dependence on carrier density. This arises due to strong dynamical screening effects in the presence of acoustic plasmons. Published by Elsevier B.V.

For these systems, we investigate (i) an accuracy of different functionals and basis sets, (ii) a solvent effect, and (iii) the impact of the chemical functionalization on optical properties of nanotubes. In contrast to B3LYP, only long-range-corrected functionals, such as CAM-B3LYP and wB97XD, properly describe the ground and excited state properties of physisorbed molecules. We found that physisorbed cation insignificantly perturbs the optical spectra of nanotubes. In contrast, covalently bound complexes demonstrate strong redshifts and brightening of the lowest exciton that is optically dark in pristine nanotubes. However, the energy and oscillator strength of the lowest state are dictated by the position of the molecule on the nanotube. Thus, if controllable and selective chemical functionalization is realized, the PL of nanotubes could be improved. (C) 2012 Elsevier B.V. All rights reserved.

TI Bonded Radii and the Contraction of the Electron Density of the Oxygen Atom by Bonded Interactions SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID BORN REPULSIVE PARAMETERS; SILICA POLYMORPH COESITE; EFFECTIVE IONIC-RADII; PROMOLECULE RADII; MODEL STRUCTURES; EARTH MATERIALS; ALKALI HALIDES; CRITICAL-POINT; WAVE FUNCTIONS; CRYSTAL RADII AB The bonded radii for more than 700 bonded pairs of atoms, comprising more than 50 oxide crystals, extracted from experimental and theoretical electron density distributions, are averaged and compared with the ionic radii for first, second, and third row atoms. At odds with the assumption of a "fixed" ionic radius of 1.40 angstrom for the oxide anion, the bonded radius for the anion, r(b)(O), decreases systematically from 1.40 to 0.65 angstrom as the electron density distribution of the atom is progressively polarized and contracted by its bonded interactions. The radii for the more electropositive metal atoms agree with the ionic radii when the electron density distribution of the anion is largely unpolarized by its bonded interactions. However, those for the more electronegative metal atoms are progressively larger than the ionic radii as the electron density distribution of the anion is progressively polarized and contracted along the bond vectors with decreasing bond length. The progressive decrease of r(b)(O) indicates that the compilation of sets of ionic radii, based on a fixed radius for the oxide anion, is problematic and impacts the accuracy of the ionic radii for the metal atoms. The assumption of a "fixed" radius for the anion, made in the derivation of sets of radii, not only results in unrealistic negative ionic radii for the more electronegative atoms but also in ionic radii that are as much as 0.5 angstrom smaller than the bonded radii, particularly for the more electronegative M atoms. The lack of agreement between the ionic and the bonded radii for the more shared bonded interactions is ascribed to the progressive increase in the polarization and contraction of the electron density of the oxide anion by the bonded interactions with a concomitant decrease in the radius of the anion, a factor that was largely neglected in the compilation of the ionic radii for fluoride, oxide, sulfide, and nitride crystals. The close agreement of the bonded radii and procrystal bonded radii is consistent with the argument that the chemical forces that govern the electron density distributions and bonded radii are largely atomic in nature, resulting in comparable electron density distributions.

TI Density Functional Kinetic Monte Carlo Simulation of Water-Gas Shift Reaction on Cu/ZnO SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID LOW-TEMPERATURE; SURFACE-REACTIONS; CO ADSORPTION; SUPPORTED CU; CATALYSTS; COPPER; CU(111); ZNO; MODEL; OXIDE AB We describe a density functional theory based kinetic Monte Carlo study of the water-gas shift (WGS) reaction catalyzed by Cu nanoparticles supported on a ZnO surface. DFT calculations were performed to obtain the energetics of the relevant atomistic processes. Subsequently, the DFT results were employed as an intrinsic database in kinetic Monte Carlo simulations that account for the spatial distribution, fluctuations, and evolution of chemical species under steady-state conditions. Our simulations show that, in agreement with experiments, the H-2 and CO2 production rates strongly depend on the size and structure of the Cu nanoparticles, which are modeled by single-layer nano islands in the present work. The WGS activity varies linearly with the total number of edge sites of Cu nano islands. In addition, examination of different elementary processes has suggested competition between the carboxyl and the redox mechanisms, both of which contribute significantly to the WGS reactivity. Our results have also indicated that both edge sites and terrace sites are active and contribute to the observed H-2 and CO2 productivity.

The glass and crystal structure was studied with Raman spectroscopy, nuclear magnetic resonance (NMR), X-ray diffraction, and electron microscopy. As the chloride fraction increased, the medium-range order in the glass decreased up to a critical point (similar to 14 mass% of mixed chlorides), above which the glasses became phase-separated. Resulting phases were a TeO2/PbO-rich phase and a crystalline phase rich in alkali chlorides. Contrary to previous studies, the Te-125 NMR indicates that the Te site distribution did not change with increased concentrations of M+, M2+, and M3+ cations, but rather is controlled by the Te/Pb molar ratio. The Pb-207 NMR shows that two Pb species exist and their relative concentration changes monotonically with the addition of mixed chlorides, indicating that the additives to the TeO2-PbO glass are accommodated by changing the Pb species. The Na-23 and Cl-35 NMR indicate that Na and Cl are distributed in the single-phase glass up to the critical point and, at higher concentrations, partition to crystalline phases. At the 14 mass% loading, transmission electron microscopy shows that the sample contains similar to 10 nm seed nuclei that increase in size and concentration with exposure to the electron beam.

TI The Effect of Hydrogen and Fluorine Coadsorption on the Piezoelectric Properties of Graphene SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID BILAYER GRAPHENE; MONOLAYER GRAPHENE; PERFORMANCE; ACTUATORS; DEVICES; BANDGAP; SURFACE; FILMS; SIO2 AB Motivated by a search for electromechanical coupling in monolayer materials, we study graphene chemically modified by hydrogen adsorbed on one side and fluorine adsorbed on the other side. Such adsorption under experimental conditions can potentially lead to a variety of configurations of atoms on the surface. We perform an exhaustive evaluation of candidate configurations for two stoichiometries, C2HF and C4HF, and examine their electromechanical properties using density functional theory. While all configurations exhibit an e(31), piezoelectric effect, the lowest energy configuration additionally exhibits an e(11), effect. Therefore, both e(31), and e(11), piezoelectricity can potentially be engineered into nonpiezoelectric monolayer graphene, providing an avenue for monolithic integration of electronic and electromechanical devices in graphene monolayers for resonators, sensors, and nanoelectromechanical systems (NEMS).

Morphological studies using scanning electron microscopy confirm that the nanowire morphology is retained after annealing in ammonia at temperatures up to 800 degrees C. However, significant indium etching and composition inhomogeneities are observed for higher indium composition nanowires (x = 0.28, 0.42), as measured by energy-dispersive X-ray spectroscopy and Z-contrast scanning transmission electron microscopy. Structural analyses, using X-ray diffraction and high-resolution transmission electron microscopy, indicate that this is a result of the greater thermal instability of higher indium composition nanowires. The effect of these structural changes on the optical quality of InGaN nanowires is examined using steady-state and time-resolved photoluminescence measurements. Annealing in ammonia enhances the integrated photoluminescence intensity of InxGa1-xN nanowires by up to a factor of 4.11 +/- 0.03 (for x = 0.42) by increasing the rate of radiative recombination. Fitting of photoluminescence decay curves to a Kohlrausch stretched exponential indicates that this increase is directly related to a larger distribution of recombination rates from composition inhomogeneities caused by annealing. The results demonstrate the role of thermal instability on the improved optical properties of InGaN nanowires annealed in ammonia.

Luminescence depletion imaging used a Gaussian shaped excitation laser pulse overlapped with a depletion pulse, shaped into a doughnut profile, with zero intensity in the center. Luminescence from a subdiffraction volume is collected from the central portion of the excitation spot, where no depletion takes place. Up to 92% depletion of the luminescence signal was achieved. An average full width at half-maximum of 40 +/- 10 nm was measured in the lateral direction for isolated g-NQDs at an air interface using luminescence depletion imaging, whereas the average full width at half-maximum was 450 +/- 90 nm using diffraction-limited, confocal luminescence imaging. Time-gating of the luminescence depletion data was required to achieve the stated spatial resolution. No observable photobleaching of the g-NQDs was present in the measurements, which allowed imaging with a dwell time of 250 ms per pixel to obtain images with a high signal-to-noise ratio. The mechanism for luminescence depletion is likely stimulated emission, stimulated absorption, or a combination of the two. The g-NQDs fulfill a need for versatile, photostable tags for subdiffraction imaging schemes where high laser powers or long exposure times are used.

This procedure exploits the UV-induced immobilization chemistry of alkenes to gallium phosphide and silicon surfaces. The photochemical grafting provides a means for patterning molecular linkers with attachment points to catalysts. Successful grafting is characterized by grazing angle attenuated total reflection Fourier transform infrared spectroscopy (GATR-FTIR), which shows catalyst vibrational modes, as well as Xray photoelectron spectroscopy (XPS), which confirms the presence of intact Ni complex on the surface. The modular nature of this approach allows independent modification of the light absorber, bridging material, anchoring functionality, or catalyst as new materials and discoveries emerge.

These versatile building blocks have generated much scientific interest and found applications in bioimaging, tracking lighting, lasing, photovoltaics, photocatalysis, thermoelectrics, and spintronics. Despite these advances, important challenges remain, notably how to produce semiconductor nanostructures with predetermined architecture, how to produce metastable semiconductor nanostructures that are hard to isolate by conventional syntheses, and how to control the degree of surface loading or valence per nanocrystal. Molecular chemists are very familiar with these issues and can use their expertise to help solve these challenges. In this Perspective, we present our group's recent work on bottom-up molecular control of nanoscale composition and morphology, low-temperature photochemical routes to semiconductor heterostructures and metastable phases, solar-to-chemical energy conversion with semiconductor-based photocatalysts, and controlled surface modification of colloidal semiconductors that bypasses ligand exchange.

CA ALICE Collaboration TI Transverse Momentum Distribution and Nuclear Modification Factor of Charged Particles in p plus Pb Collisions at root(NN)-N-s=5.02 TeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID ROOT-S(NN)=2.76 TEV; CGC PREDICTIONS; LHC; SUPPRESSION AB The transverse momentum (pT) distribution of primary charged particles is measured in minimum bias (non-single-diffractive) p + Pb collisions at root(NN)-N-s = 5.02 TeV with the ALICE detector at the LHC. The pT spectra measured near central rapidity in the range 0.5< p(T) < 20 GeV/c exhibit a weak pseudorapidity dependence. The nuclear modification factor R-pPb is consistent with unity for p(T) above 2 GeV/c. This measurement indicates that the strong suppression of hadron production at high p(T) observed in Pb + Pb collisions at the LHC is not due to an initial-state effect. The measurement is compared to theoretical calculations. DOI: 10.1103/PhysRevLett.110.082302 C1 [Abelev, B.; Garishvili, I.; Soltz, R.] Lawrence Livermore Natl Lab, Livermore, CA 94550 USA.

CA CMS Collaboration TI Study of the Mass and Spin-Parity of the Higgs Boson Candidate via Its Decays to Z Boson Pairs SO PHYSICAL REVIEW LETTERS LA English DT Article ID BROKEN SYMMETRIES; MODEL; LHC; PARTICLES; LEPTONS; SEARCH AB A study is presented of the mass and spin-parity of the new boson recently observed at the LHC at a mass near 125 GeV. An integrated luminosity of 17: 3 fb(-1), collected by the CMS experiment in proton-proton collisions at center-of-mass energies of 7 and 8 TeV, is used. The measured mass in the ZZ channel, where both Z bosons decay to e or mu pairs, is 126: 2 +/- 0.6(stat) +/- 0. 2(syst) GeV. The angular distributions of the lepton pairs in this channel are sensitive to the spin-parity of the boson. Under the assumption of spin 0, the present data are consistent with the pure scalar hypothesis, while disfavoring the pure pseudoscalar hypothesis.

TI Dissociation Transition of a Composite Lattice of Magnetic Vortices in the Flux-Flow Regime of Two-Band Superconductors SO PHYSICAL REVIEW LETTERS LA English DT Article ID METALLIC HYDROGEN; VORTEX LATTICE; MIXED-STATE; TRANSFORMER; FILMS; LIQUID AB In multiband superconductors, each superconducting condensate supports vortices with fractional quantum flux. In the ground state, vortices in different bands are spatially bounded together to form a composite vortex, carrying one quantum flux Phi(0). Here we predict dissociation of the composite vortices lattice in the flux flow state due to the disparity of the vortex viscosity and flux of the vortex in different bands. For a small driving current, composite vortices start to deform, but the constituting vortices in different bands move with the same velocity. For a large current, composite vortices dissociate and vortices in different bands move with different velocities. The dissociation transition shows up as an increase of flux flow resistivity. In the dissociated phase, Shapiro steps are developed when an ac current is superimposed with a dc current.

TI Making use of x-ray optical effects in photoelectron-, Auger electron-, and x-ray emission spectroscopies: Total reflection, standing-wave excitation, and resonant effects SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID RESOLVED PHOTOEMISSION-SPECTROSCOPY; ALPHA-GAMMA-TRANSITION; DETAILED ANALYSIS; SCATTERING; SURFACE; MAGNETORESISTANCE; CE; REFRACTION; INTERFACE; SPECTRA AB We present a general theoretical methodology and related open-access computer program for carrying out the calculation of photoelectron, Auger electron, and x-ray emission intensities in the presence of several x-ray optical effects, including total reflection at grazing incidence, excitation with standing-waves produced by reflection from synthetic multilayers and at core-level resonance conditions, and the use of variable polarization to produce magnetic circular dichroism. Calculations illustrating all of these effects are presented, including in some cases comparisons to experimental results. Sample types include both semi-infinite flat surfaces and arbitrary multilayer configurations, with interdiffusion/roughness at their interfaces. These x-ray optical effects can significantly alter observed photoelectron, Auger, and x-ray intensities, and in fact lead to several generally useful techniques for enhancing surface and buried-layer sensitivity, including layer-resolved densities of states and depth profiles of element-specific magnetization. The computer program used in this study should thus be useful for a broad range of studies in which x-ray optical effects are involved or are to be exploited in next-generation surface and interface studies of nanoscale systems.

TI Direct Delta MBPT(2) method for ionization potentials, electron affinities, and excitation energies using fractional occupation numbers SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID COUPLED-CLUSTER METHOD; DENSITY-FUNCTIONAL-THEORY; EXCITED-STATES; CONFIGURATION-INTERACTION; TRANSITION OPERATOR; PERTURBATION-THEORY; OPEN-SHELL; MOLECULES; PROBABILITIES; ATOMS AB A direct method (D-Delta MBPT(2)) to calculate second-order ionization potentials (IPs), electron affinities (EAs), and excitation energies is developed. The Delta MBPT(2) method is defined as the correlated extension of the Delta HF method. Energy differences are obtained by integrating the energy derivative with respect to occupation numbers over the appropriate parameter range. This is made possible by writing the second-order energy as a function of the occupation numbers. Relaxation effects are fully included at the SCF level. This is in contrast to linear response theory, which makes the D-Delta MBPT(2) applicable not only to single excited but also higher excited states. We show the relationship of the D-Delta MBPT(2) method for IPs and EAs to a second-order approximation of the effective Fock-space coupled-cluster Hamiltonian and a second-order electron propagator method. We also discuss the connection between the D-Delta MBPT(2) method for excitation energies and the CIS-MP2 method. Finally, as a proof of principle, we apply our method to calculate ionization potentials and excitation energies of some small molecules. For IPs, the Delta MBPT(2) results compare well to the second-order solution of the Dyson equation. For excitation energies, the deviation from equation of motion coupled cluster singles and doubles increases when correlation becomes more important. When using the numerical integration technique, we encounter difficulties that prevented us from reaching the Delta MBPT(2) values. Most importantly, relaxation beyond the Hartree-Fock level is significant and needs to be included in future research. (C) 2013 American Institute of Physics.

The experimental conditions are such that the complexes form at temperatures above the temperature of observation. These complexes can be regarded as polymeric chains of varying length, with an Ag4S pyramid at the core of each monomeric unit. Steps may catalyze the formation of the chains and this mechanism may be reflected in the chain length distribution. (C) 2013 American Institute of Physics.

TI Benchmark oxygen-oxygen pair-distribution function of ambient water from x-ray diffraction measurements with a wide Q-range SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID RADIAL-DISTRIBUTION FUNCTIONS; LIQUID WATER; SCATTERING EXPERIMENTS; NEUTRON-DIFFRACTION; MOLECULAR-DYNAMICS; HYDROGEN; QUALITY; TEMPERATURE; SIMULATION; GLASSES AB Four recent x-ray diffraction measurements of ambient liquid water are reviewed here. Each of these measurements represents a significant development of the x-ray diffraction technique applied to the study of liquid water. Sources of uncertainty from statistical noise, Q-range, Compton scattering, and self-scattering are discussed. The oxygen-hydrogen contribution to the measured x-ray scattering pattern was subtracted using literature data to yield an experimental determination, with error bars, of the oxygen-oxygen pair-distribution function, g(OO)(r), which essentially describes the distribution of molecular centers. The extended Q-range and low statistical noise of these measurements has significantly reduced truncation effects and related errors in the g(OO)(r) functions obtained. From these measurements and error analysis, the position and height of the nearest neighbor maximum in g(OO)(r) were found to be 2.80(1) angstrom and 2.57(5) respectively. Numerical data for the coherent differential x-ray scattering cross-section I-X(Q), the oxygen-oxygen structure factor S-OO(Q), and the derived g(OO)(r) are provided as benchmarks for calibrating force-fields for water.

TI Abundant SAR11 viruses in the ocean SO NATURE LA English DT Article ID PHAGE PREDATION; MARINE; PROCHLOROCOCCUS; COMMUNITIES; POPULATION; DYNAMICS; GENOMES AB Several reports proposed that the extraordinary dominance of the SAR11 bacterial clade in ocean ecosystems could be a consequence of unusual mechanisms of resistance to bacteriophage infection, including 'cryptic escape' through reduced cell size(1) and/or K-strategist defence specialism(2). Alternatively, the evolution of high surface-to-volume ratios coupled with minimal genomes containing high-affinity transporters enables unusually efficient metabolism for oxidizing dissolved organic matter in the world's oceans that could support vast population sizes despite phage susceptibility. These ideas are important for understanding plankton ecology because they emphasize the potentially important role of top-down mechanisms in predation, thus determining the size of SAR11 populations and their concomitant role in biogeochemical cycling. Here we report the isolation of diverse SAR11 viruses belonging to two virus families in culture, for which we propose the name 'pelagiphage', after their host. Notably; the pelagiphage genomes were highly represented in marine viral metagenomes, demonstrating their importance in nature. One of the new phages, HTVC010P, represents a new podovirus subfamily more abundant than any seen previously, in all data sets tested, and may represent one of the most abundant virus subfamilies in the biosphere. This discovery disproves the theory that SAR11 cells are immune to viral predation and is consistent with the interpretation that the success of this highly abundant microbial clade is the result of successfully evolved adaptation to resource competition.

TI Energy-dependent crossover from anisotropic to isotropic magnetic dispersion in lightly doped La1.96Sr0.04CuO4 SO PHYSICAL REVIEW B LA English DT Article ID HIGH-T-C; HIGH-TEMPERATURE SUPERCONDUCTOR; COPPER-OXIDE SUPERCONDUCTORS; NEUTRON-SCATTERING; STRIPES; LA2-XSRXCUO4; EXCITATIONS; LA2CUO4; LIQUID; ORDER AB Inelastic neutron-scattering experiments have been performed on lightly doped La1.96Sr0.04CuO4, which shows diagonal incommensurate spin correlations at low temperatures. We previously reported that this crystal, with a single orthorhombic domain, exhibits the "hourglass" dispersion at low energies [Phys. Rev. Lett. 101, 197001 (2008)]. In this paper, we investigate in detail the energy evolution of the magnetic excitations up to 65 meV. It is found that the anisotropic excitations at low energies, dispersing only along the spin modulation direction, cross over to an isotropic, conical dispersion that resembles spin waves in the parent compound La2CuO4. The change from twofold to full symmetry on crossing the waist of the hourglass reproduces behavior first identified in studies of underdoped YBa2Cu3O6+x. We discuss the significance of these results. DOI: 10.1103/PhysRevB.87.054508 C1 [Matsuda, M.; Granroth, G. E.] Oak Ridge Natl Lab, Quantum Condensed Matter Div, Oak Ridge, TN 37831 USA.

CA CDF Collaboration TI Measurement of W-boson polarization in top-quark decay using the full CDF Run II data set SO PHYSICAL REVIEW D LA English DT Article ID COLLIDER DETECTOR; FERMILAB AB We measure the polarization of W bosons from top-quark (t) decays into final states with a charged lepton and jets, t (t) over bar -> W(+)bW(-)(b) over bar -> lvbq (q) over bar (1)(b) over bar, using the full Run II data set collected by the CDF II detector, corresponding to an integrated luminosity of 8.7 fb(-1). A model-independent method simultaneously determines the fraction of longitudinal (f(0)) and right-handed (f(+)) W bosons to yield f(0) = 0.726 +/- 0.066(stat) +/- 0.067(syst) and f(+) = -0.045 +/- 0.044(stat) +/- 0.058(syst) with a correlation coefficient of -0.69. Additional results are presented under various standard model assumptions. No significant discrepancies with the standard model are observed. DOI: 10.1103/PhysRevD.87.031104 C1 [Chen, Y.

CA Belle Collaboration TI Measurements of branching fractions and direct CP asymmetries for B -> K pi, B -> pi pi and B -> KK decays SO PHYSICAL REVIEW D LA English DT Article ID MONTE-CARLO; PUZZLE; SUPERSYMMETRY; VIOLATION; PHOTOS AB We report measurements of the branching fractions and direct CP asymmetries (A(CP)) for B -> K pi, pi pi and KK decays (but not pi(0) pi(0)) based on the final data sample of 772 x 10(6) B (B) over bar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We set a 90% confidence-level upper limit for K+K- at 2.0 x 10(-7); all other decays are observed with branching fractions ranging from 10(-6) to 10(-5). In the B-0/(B) over bar (0) -> K-+/-pi(-/+) mode, we confirm Belle's previously reported large A(CP) with a value of -0.069 +/- 0.014 +/- 0.007 and a significance of 4.4 sigma. For all other flavor-specific modes, we find A(CP) values consistent with zero, including A(CP)(K+pi(0)) = +0.043 +/- 0.024 +/- 0.007 with 1.8 sigma significance. The difference of CP asymmetry between B-+/- -> K-+/- pi(0) and B-0/(B) over bar (0) K-+/-pi(-/+) is found to be Delta A(K pi) equivalent to A(CP)(K+pi(0)) - A(CP)(K+pi(-)) = +0.112 +/- 0.027 +/- 0.007 with 4.0 sigma significance. We also calculate the ratios of partial widths for the B -> K pi decays. Using our results, we test the validity of the sum rule A(CP)(K+pi(-)) + A(CP)(K-0 pi(+)) Gamma(K-0 pi(+))/Gamma(K+pi(-)) - A(CP)(K+pi(0))2 Gamma(K+pi(0))/Gamma(K+pi(-)) - A(CP)(K-0 pi(0))2 Gamma(K-0 pi(0))/Gamma(K+pi(-)) =0 and obtain a sum of -0.270 +/- 0.132 +/- 0.060 with 1:9 sigma significance.

TI Gadolinium-153 as a brachytherapy isotope SO PHYSICS IN MEDICINE AND BIOLOGY LA English DT Article ID TRANSMISSION DATA; MONTE-CARLO; DOSIMETRY; TM-170; RECOMMENDATIONS; YB-169; IR-192; CO-57; SPECT AB The purpose of this work was to present the fundamental dosimetric characteristics of a hypothetical Gd-153 brachytherapy source using the AAPM TG-43U1 dose-calculation formalism. Gadolinium-153 is an intermediate-energy isotope that emits 40-100 keV photons with a half-life of 242 days. The rationale for considering Gd-153 as a brachytherapy source is for its potential of patient specific shielding and to enable reduced personnel shielding requirements relative to Ir-192, and as an isotope for interstitial rotating shield brachytherapy (I-RSBT). A hypothetical Gd-153 brachytherapy source with an active core of 0.84 mm diameter, 10 mm length and specific activity of 5.55 TBq of Gd-153 per gram of Gd was simulated with Geant4. The encapsulation material was stainless steel with a thickness of 0.08 mm. The radial dose function, anisotropy function and photon spectrum in water were calculated for the Gd-153 source. The simulated Gd-153 source had an activity of 242 GBq and a dose rate in water 1 cm off axis of 13.12 Gy h(-1), indicating that it would be suitable as a low-dose-rate or pulsed-dose-rate brachytherapy source. The beta particles emitted have low enough energies to be absorbed in the source encapsulation. Gadolinium-153 has an increasing radial dose function due to multiple scatter of low-energy photons. Scattered photon dose takes over with distance from the source and contributes to the majority of the absorbed dose. The anisotropy function of the Gd-153 source decreases at low polar angles, as a result of the long active core. The source is less anisotropic at polar angles away from the longitudinal axes. The anisotropy function increases with increasing distance. The Gd-153 source considered would be suitable as an intermediate-energy low-dose-rate or pulsed-dose-rate brachytherapy source. The source could provide a means for I-RSBT delivery and enable brachytherapy treatments with patient specific shielding and reduced personnel shielding requirements relative to Ir-192.

TI A quenched study of the Schrodinger functional with chirally rotated boundary conditions: Non-perturbative tuning SO NUCLEAR PHYSICS B LA English DT Article ID QUARK MASS RENORMALIZATION; LATTICE QCD; 2-LOOP COMPUTATION; IMPROVEMENT; FLAVORS AB The use of chirally rotated boundary conditions provides a formulation of the Schrodinger functional that is compatible with automatic O(a) improvement of Wilson fermions up to O(a) boundary contributions. The elimination of bulk O(a) effects requires the non-perturbative tuning of the critical mass and one additional boundary counterterm. We present the results of such a tuning in a quenched setup for several values of the renormalized gauge coupling, from perturbative to non-perturbative regimes. and for a range of lattice spacings. We also check that the correct boundary conditions and symmetries are restored in the continuum limit. (C) 2012 Elsevier B.V. All rights reserved. C1 [Lopez, J.

This tuning is required to eliminate bulk O(a) cutoff effects in physical correlation functions. Using our tuning results obtained in Gonzalez Lopez et al. (2013) [1] we perform scaling and universality tests analyzing the residual O(a) cutoff effects of several step-scaling functions and we compute renormalization factors at the matching scale. As an example of possible application of the chi SF we compute the renormalized strange quark mass using large volume data obtained from Wilson twisted mass fermions at maximal twist.

CA CMS Collaboration TI Measurement of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) Polarizations in pp Collisions at root s 7 TeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID HEAVY QUARKONIUM AB The polarizations of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) mesons are measured in proton-proton collisions at root s = 7 TeV, using a data sample of Upsilon(nS) -> mu(+)mu(-) decays collected by the CMS experiment, corresponding to an integrated luminosity of 4.9 fb(-1). The dimuon decay angular distributions are analyzed in three different polarization frames. The polarization parameters lambda(theta), lambda(phi), and lambda(theta phi), as well as the frame-invariant quantity (lambda) over tilde, are presented as a function of the Upsilon(nS) transverse momentum between 10 and 50 GeV, in the rapidity ranges vertical bar y vertical bar < 0: 6 and 0: 6 < vertical bar y vertical bar < 1.2. No evidence of large transverse or longitudinal polarizations is seen in the explored kinematic region. DOI: 10.1103/PhysRevLett.110.081802 C1 [Chatrchyan, S.; Khachatryan, V.; Sirunyan, A.

When hydrogen atoms are immersed randomly into the deuterated ice, a typical vibrational frequency of OH stretching mode is observed to be similar to that from the pure H2O ice. When focusing on the correlation of isolated neighboring OH stretching, a narrower and blue shifted peak is observed at the high frequency range as a result of the screening from the complex many body correlations by D2O environment. It is also specifically related to the symmetric intermolecular correlations between neighboring OH stretching modes. More enhanced high frequency range can be explained by the expansion of such two body correlations to collective many body correlations among all possible OH stretching modes. This contribution becomes important when it involves in chemical interactions via excitation of such vibrational states.

SAXS experiments on 5.2, 13.3, and 13.8 nm hollow-shell gamma-Fe3O4 NPs, and 6 nm core/14.8 nm hollow-shell Au/Fe3O4 NPs, reveal the significantly high (higher than solvent) electron density of the void inside the hollow shell. In high-pressure DAC experiments using Ne as pressure-transmitting medium, formation of nanocrystalline Ne inside hollow NPs is not detected by XRD, indicating that the oxide shell is impenetrable. Also, FTIR analysis on solutions of hollow-shell gamma-Fe3O4 NPs fragmented upon refluxing shows no evidence of organic molecules from the void inside, excluding the possibility that organic molecules get through the iron oxide shell during synthesis. High-pressure DAC experiments on Au/Fe3O4 core/hollow-shell NPs show good transmittance of the external pressure to the gold core, indicating the presence of the pressure-transmitting medium in the gap between the core and the hollow shell. Overall, our data reveal the presence of most likely small fragments of iron and/or iron oxide in the void of the hollow NPs. The iron oxide shell seems to be non-porous and impenetrable by gases and liquids.

TI Characterization of [4Fe-4S] Cluster Vibrations and Structure in Nitrogenase Fe Protein at Three Oxidation Levels via Combined NRVS, EXAFS, and DFT Analyses SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID RESONANCE RAMAN-SPECTROSCOPY; AZOTOBACTER-VINELANDII NITROGENASE; FERROUS FE4S4 CLUSTER; DENSITY-FUNCTIONAL THEORY; ABSORPTION FINE-STRUCTURE; X-RAY CRYSTALLOGRAPHY; IRON-SULFUR CLUSTERS; ELECTRON-TRANSFER; SYNTHETIC ANALOGS; CRYSTAL-STRUCTURE AB Azotobacter vinelandii nitrogenase Fe protein (A nu 2) provides a rare opportunity to investigate a [4Fe-45] cluster at three oxidation levels in the same protein environment. Here, we report the structural and vibrational changes of this cluster upon reduction using a combination of NRVS and EXAFS spectroscopies and DFT calculations. Key to this work is the synergy between these three techniques as each generates highly complementary information and their analytical methodologies are interdependent. Importantly, the spectroscopic samples contained no glassing agents. NRVS and DFT reveal a systematic 10-30 cm(-1) decrease in Fe-S stretching frequencies with each added electron. The "oxidized" [4Fe-4S](2+) state spectrum is consistent with and extends previous resonance Raman spectra. For the "reduced" [4Fe-4S](1+) state in Fe protein, and for any "all-ferrous" [4Fe-4S](0) cluster, these NRVS spectra are the first available vibrational data. NRVS simulations also allow estimation of the vibrational disorder for Fe-S and Fe-Fe distances, constraining the EXAFS analysis and allowing structural disorder to be estimated. For oxidized A nu 2, EXAFS and DFT indicate nearly equal Fe-Fe distances, while addition of one electron decreases the cluster symmetry. However, addition of the second electron to form the all-ferrous state induces significant structural change. EXAFS data recorded to k = 21 angstrom(-1) indicates a 1:1 ratio of Fe-Fe interactions at 2.56 angstrom and 2.75 angstrom, a result consistent with DFT. Broken symmetry (BS) DFT rationalizes the interplay between redox state and the Fe-S and Fe-Fe distances as predominantly spin-dependent behavior inherent to the [4Fe-4S] cluster and perturbed by the A nu 2 protein environment.

TI Sensitizing Curium Luminescence through an Antenna Protein To Investigate Biological Actinide Transport Mechanisms SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID HUMAN-SERUM TRANSFERRIN; INTRAMOLECULAR ENERGY-TRANSFER; LASER FLUORESCENCE SPECTROSCOPY; EQUILIBRIUM-CONSTANTS; CRYSTAL-STRUCTURE; IRON RELEASE; BINDING; RECEPTOR; AMERICIUM; CM(III) AB Worldwide stocks of actinides and lanthanide fission products produced through conventional nuclear spent fuel are increasing continuously, resulting in a growing risk of environmental and human exposure to these toxic radioactive metal ions. Understanding the biomolecular pathways involved in mammalian uptake, transport and storage of these f-elements is crucial to the development of new decontamination strategies and could also be beneficial to the design of new containment and separation processes. To start unraveling these pathways, our approach takes advantage of the unique spectroscopic properties of trivalent curium. We clearly show that the human iron transporter transferrin acts as an antenna that sensitizes curium luminescence through intramolecular energy transfer. This behavior has been used to describe the coordination of curium within the two binding sites of the protein and to investigate the recognition of curium-transferrin complexes by the cognate transferrin receptor. In addition to providing the first protein- curium spectroscopic characterization, these studies prove that transferrin receptor-mediated endocytosis is a viable mechanism of intracellular entry for trivalent actinides such as curium and provide a new tool utilizing the specific luminescence of curium for the determination of other biological actinide transport mechanisms.

TI Heterogeneous Catalysts Need Not Be so "Heterogeneous": Monodisperse Pt Nanocrystals by Combining Shape-Controlled Synthesis and Purification by Colloidal Recrystallization SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID CRYSTAL PLATINUM-ELECTRODES; NOBLE-METAL NANOPARTICLES; FORMIC-ACID OXIDATION; WATER-GAS SHIFT; CO OXIDATION; POLYCRYSTALLINE PLATINUM; AU-CEO2 CATALYSTS; OXYGEN REDUCTION; PT(111) SURFACE; SUPERLATTICES AB Well-defined surfaces of Pt have been extensively studied for various catalytic processes. However, industrial catalysts are mostly composed of fine particles (e.g., nanocrystals), due to the desire for a high surface to volume ratio. Therefore, it is very important to explore and understand the catalytic processes both at nanoscale and on extended surfaces. In this report, a general synthetic method is described to prepare Pt nanocrystals with various morphologies. The synthesized Pt nanocrystals are further purified by exploiting the "self-cleaning" effect which results from the "colloidal recrystallization" of Pt supercrystals. The resulting high-purity nanocrystals enable the direct comparison of the reactivity of the {111} and {100} facets for important catalytic reactions. With these high-purity Pt nanocrystals, we have made several observations: Pt octahedra show higher poisoning tolerance in the electrooxidation of formic acid than Pt cubes; the oxidation of CO on Pt nanocrystals is structure insensitive when the partial pressure ratio p(o2)/p(co) is close to or less than 0.5, while it is structure sensitive in the O-2-rich environment; Pt octahedra have a lower activation energy than Pt cubes when catalyzing the electron transfer reaction between hexacyanoferrate (III) and thiosulfate ions. Through electrocatalysis, gas-phase-catalysis of CO oxidation, and a liquid-phase-catalysis of electron transfer reaction, we demonstrate that high quality Pt nanocrystals which have {111} and {100} facets selectively expose are ideal model materials to study catalysis at nanoscale.

TI From Yellow to Black: Dramatic Changes between Cerium(IV) and Plutonium(IV) Molybdates SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID RAY-ABSORPTION-SPECTROSCOPY; X-RAY; CRYSTAL-STRUCTURES; TRANSURANIUM ELEMENTS; CHLORIDE DERIVATIVES; MAGNETIC-PROPERTIES; SINGLE-CRYSTAL; STRUCTURAL-CHARACTERIZATION; ELECTRICAL-PROPERTIES; PROPOSED SURROGATES AB Hydrothermal reactions of CeCl3 and PuCl3 with MoO3 and Cs2CO3 yield surprisingly different results. Ce3Mo6O24(H2O)(4) crystallizes as bright yellow plates (space group C2/c, a = 12.7337(7) angstrom, b = 22.1309(16) angstrom, c = 7.8392(4) angstrom, beta = 96.591(4)degrees, V = 2194.6(2) angstrom(3)), whereas CsPu3Mo6O24(H2O) crystallizes as semiconducting black-red plates (space group C2/c, a = 12.633(5) angstrom, b = 21.770(8) angstrom, c = 7.743(7) angstrom, beta = 96.218(2)degrees, V = 2117(2) angstrom(3)). The topologies of the two compounds are similar, with channel structures built from disordered Mo(VI) square pyramids and (RE)O-8 square antiprisms (RE = Ce(IV), Pu(IV)). However, the Pu(IV) compound contains Cs+ in its channels, while the channels in CsPu3Mo6O24(H2O)(4) contain water molecules. Disorder and an ambiguous oxidation state of Mo lead to the formula CsPu3Mo6O24(H2O), where one Mo site is Mo(V) and the rest are Mo(VI). X-ray absorption near-edge structure (XANES) experiments were performed to investigate the source of the black color of CsPu3Mo6O24(H2O). These experiments revealed Pu to be tetravalent, while the strong pre-edge absorption from the distorted molybdate anions leaves the oxidation state ambiguous between Mo(V) and Mo(VI).

NaMnGe2O6 crystallizes into a monoclinic C2/c structure with unit-cell parameters a = 9.859(2) angstrom, b = 8.7507(18) angstrom, c = 5.5724(11) angstrom, and beta = 105.64(3)degrees at 153 K.A cooperative Jahn-Teller distortion is formed by an ordering of the longest Mn-O bonds between two neighboring octahedra along the chain direction. This feature distinguishes NaMnGe2O6 from other pyroxene compounds without Jahn-Teller active cations and suggests that the Jahn-Teller distortion competes with the intrinsic local distortion in the pyroxene structure. No orbital order-disorder transition has been found up to 750 K. Like other alkali-metal pyroxenes with S > 1/2, NaMnGe2O6 (S = 2) was found to undergo a long-range antiferromagnetic (AF) ordering at T-N = 7 K due to intrachain and interchain exchange interactions. Due to the peculiar structural features and the corresponding magnetic coupling, the weak AF spin ordering gives way to a ferromagnetic-like state at a sufficiently high magnetic field. Specific-heat measurements demonstrated that a large portion of the magnetic entropy, >60%, has been removed above T-N as a result of strong spin correlations within the quasi-one-dimensional Mn3*-spin chains. The Reitveld refinement of neutron powder diffraction data gives a commensurate magnetic structure defined by k = [0 0 0.5] with Mn moments aligned mainly along the c-axis with a small component along both a- and b-axes.

To that end, three-dimensional (3D) data analysis of feedback-like processes may be considered. Methods: To detect infectious disease data patterns, a systems biology (SB) and evolutionary biology (EB) approach was evaluated, which utilizes leukocyte data structures designed to diminish data variability and enhance discrimination. Using data collected from one avian and two mammalian (human and bovine) species infected with viral, parasite, or bacterial agents (both sensitive and resistant to antimicrobials), four data structures were explored: (i) counts or percentages of a single leukocyte type, such as lymphocytes, neutrophils, or macrophages (the classic approach), and three levels of the SB/EB approach, which assessed (ii) 2D, (iii) 3D, and (iv) multi-dimensional (rotating 3D) host-microbial interactions. Results: In all studies, no classic data structure discriminated disease-positive (D+, or observations in which a microbe was isolated) from disease-negative (D-, or microbial-negative) groups: D+ and D-data distributions overlapped. In contrast, multi-dimensional analysis of indicators designed to possess desirable features, such as a single line of observations, displayed a continuous, circular data structure, whose abrupt inflections facilitated partitioning into subsets statistically significantly different from one another. In all studies, the 3D, SB/EB approach distinguished three (steady, positive, and negative) feedback phases, in which D-data characterized the steady state phase, and D+ data were found in the positive and negative phases. In humans, spatial patterns revealed false-negative observations and three malaria-positive data classes. In both humans and bovines, methicillin-resistant Staphylococcus aureus (MRSA) infections were discriminated from non-MRSA infections. Conclusions: More information can be extracted, from the same data, provided that data are structured, their 3D relationships are considered, and well-conserved (feedback-like) functions are estimated. Patterns emerging from such structures may distinguish well-conserved from recently developed host-microbial interactions. Applications include diagnosis, error detection, and modeling.

Most notably, as temperature decreases the plasma edge shifts to lower frequencies in Bi2Se3, whereas in Bi2Te3 and Sb2Te3 it shifts to higher frequencies. In the loss function spectra we identify asymmetric broadening of the plasmon, and assign it to the presence of charge inhomogeneities. It remains to be seen if charge inhomogeneities are characteristic of all topological insulators, and whether they are of intrinsic or extrinsic nature. C1 [Dordevic, S. V.; Wolf, M.

TI Phase stability and elastic properties of Cr-V alloys SO JOURNAL OF PHYSICS-CONDENSED MATTER LA English DT Article ID SPIN-DENSITY-WAVE; TOTAL-ENERGY CALCULATIONS; X-RAY-DIFFRACTION; THERMAL-EXPANSION; THERMODYNAMIC PROPERTIES; TEMPERATURE-DEPENDENCE; FUNCTIONAL THEORY; CRYSTAL-STRUCTURE; CHROMIUM-ALLOYS; VANADIUM ALLOYS AB V is the only element in the periodic table that forms a complete solid solution with Cr and thus is particularly important in alloying strategy to ductilize Cr. This study combines first-principles density functional theory calculations and experiments to investigate the phase stability and elastic properties of Cr-V binary alloys. The cluster expansion study reveals the formation of various ordered compounds at low temperatures that were not previously known. These compounds become unstable due to the configurational entropy of bcc solid solution as the temperature is increased. The elastic constants of ordered and disordered compounds are calculated at both T = 0 K and finite temperatures. The overall trends in elastic properties are in agreement with measurements using the resonant ultrasound spectroscopy method. The calculations predict that addition of V to Cr decreases both the bulk modulus and the shear modulus, and enhances the Poisson's ratio, in agreement with experiments. Decrease in the bulk modulus is correlated to decrease in the valence electron density and increase in the lattice constant. An enhanced Poisson's ratio for bcc Cr-V alloys (compared to pure Cr) is associated with an increased density of states at the Fermi level. Furthermore, the difference charge density in the bonding region in the (110) slip plane is highest for pure Cr and decreases gradually as V is added. The present calculation also predicts a negative Cauchy pressure for pure Cr, and it becomes positive upon alloying with V. The intrinsic ductilizing effect from V may contribute, at least partially, to the experimentally observed ductilizing phenomenon in the literature. C1 [Gao, M. C.; Dogan, O.

CA CMS Collaboration TI Search for Pair Production of Third-Generation Leptoquarks and Top Squarks in pp Collisions at root s=7 TeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID PARTICLES; FORCES; UNITY AB Results are presented from a search for the pair production of third-generation scalar and vector leptoquarks, as well as for top squarks in R-parity-violating supersymmetric models. In either scenario, the new, heavy particle decays into a tau lepton and a b quark. The search is based on a data sample of pp collisions at root s = 7 TeV, which is collected by the CMS detector at the LHC and corresponds to an integrated luminosity of 4.8 fb(-1). The number of observed events is found to be in agreement with the standard model prediction, and exclusion limits on mass parameters are obtained at the 95% confidence level. Vector leptoquarks with masses below 760 GeV are excluded and, if the branching fraction of the scalar leptoquark decay to a tau lepton and a b quark is assumed to be unity, third-generation scalar leptoquarks with masses below 525 GeV are ruled out. Top squarks with masses below 453 GeV are excluded for a typical benchmark scenario, and limits on the coupling between the top squark, tau lepton, and b quark, lambda'(333) are obtained. These results are the most stringent for these scenarios to date. DOI: 10.1103/PhysRevLett.110.081801 C1 [Chatrchyan, S.; Khachatryan, V.; Sirunyan, A.

TI Evidence for the R8 Phase of Germanium SO PHYSICAL REVIEW LETTERS LA English DT Article ID RAMAN-SCATTERING; AMORPHOUS-GERMANIUM; METASTABLE PHASES; SILICON; PRESSURE; GE; INDENTATION; TRANSITIONS; PHONONS; SI AB The formation of R8 germanium is reported. The beta-Sn phase is first induced by the indentation of amorphous germanium (a-Ge) and the resultant phases on pressure release are characterized by Raman scattering. The expected Raman line frequencies for the various phases of Ge are determined from first-principles calculations using density functional perturbation theory of the zone-center phonons in the diamond, ST12, BC8, and R8 Ge phases. In addition to the R8 phase, traces of BC8 may also be present following pressure release.

TI Electron-Mediated Ferromagnetic Behavior in CoO/ZnO Multilayers SO PHYSICAL REVIEW LETTERS LA English DT Article ID SEMICONDUCTORS AB CoO/Al-doped ZnO (AZO) multilayers exhibit ferromagnetism up to similar to 300 K. The magnetic behavior oscillates with odd vs even number of Co layers in the insulating antiferromagnetic CoO and (separately) with the thickness of the AZO layers and vanishes if AZO is replaced by intrinsic ZnO. Magnetization is due to uncompensated (111) ferromagnetic planes of insulating CoO for odd numbers of atomic planes per layer that are coupled together via RKKY exchange mediated by electron carriers in the nonmagnetic AZO layers. The period of the oscillation with AZO thickness qualitatively matches the Fermi wave vector calculated from the carrier concentration measured by ordinary Hall effect. Magnetic polarization of the AZO carriers is confirmed via an anomalous Hall effect that is proportional to the magnetization.

The generic feature of the Sudakov logarithms and all order resummation is derived. This calculation shall provide us deep insights into the understanding of factorizations in the saturation formalism. We further comment on the phenomenological implications in the LHC energy regime and extension to other hard processes in small-x calculations. DOI: 10.1103/PhysRevLett.110.082301 C1 [Mueller, A.

This merger phase produces a very distinct environment around these outbursts and recent observations suggest that, in some cases, we are detecting the signatures of the past merger in the GRB afterglow. These observations allow us, for the first time, to study the specific features of the helium-merger progenitor. In this paper, we couple population synthesis calculations to our current understanding of GRB engines and common envelope evolution to make observational predictions for the helium-merger GRB population. Many mergers do not produce GRB outbursts and we discuss the implications of these mergers with the broader population of astrophysical transients.

The reaction mechanism of OH- (H2O) + CCl4 consists of two concerted steps - formation of OH- in the favorable attack conformation via the proton transfer process, and the nucleophilic substitution process in which the newly formed OH- attacks the CCl4. The free energy activation barrier is 38.2 kcal/mol at CCSD(T)/MM level of theory for this reaction, which is about 10.3 kcal/mol higher than that of the direct nucleophilic substitution mechanism of the OH- + CCl4 reaction in aqueous solution.

Combined with the inherent scalability of the resistive switching memory (RRAM), where the switching region consists of a conductive filament as small as a single atom, NWs may provide an ideal approach to reduce the device area to a range not accessible to conventional lithography. This work reviews NW-based RRAM (NWRRAM) devices. The different approaches to NWRRAMs, including (i) switching in a single metal-oxide NW, (ii) switching in a heterostructured NW with a metal-oxide segment sandwiched between NW metallic electrodes and (iii) switching in a core-shell NW, are discussed. The latter approach is then presented in detail, covering the assembly issues, the robust switching and reliability characteristics, and the scaling outlook.

TI From quasi-two-dimensional metal with ferromagnetic bilayers to Mott insulator with G-type antiferromagnetic order in Ca-3(Ru1-xTix)(2)O-7 SO PHYSICAL REVIEW B LA English DT Article ID RUTHENATE SR3RU2O7; SUPERCONDUCTIVITY; TRANSITION; SR2RUO4; CA2-XSR(X)RUO4; SCATTERING; CA3RU2O7; PHYSICS AB We report the electronic and magnetic phase diagram of Ca-3(Ru1-xTix)(2)O-7. With Ti doping, the system evolves from a quasi-two-dimensional metal with ferromagnetic (FM) bilayers coupled antiferromagnetically along the c axis (AFM-b) for x = 0, to a weakly localized state for 0 < x < 0.05, and finally to a Mott insulator with G-type antiferromagnetic (G-AFM) order for x >= 0.05. The magnetic state switching from the AFM-b to the G-AFM occurs in the weakly localized state near x = 0.03. We show that such a magnetic transition is controlled by the charge carrier itinerancy and can be understood in light of competing interactions between FM double exchange and AFM superexchange. An incommensurate component is also observed due to competing magnetic interactions. DOI: 10.1103/PhysRevB.87.085125 C1 [Peng, Jin; Wang, Gaochao; Ortmann, J. E.; Fobes, David; Mao, Z.

With decreasing film thickness, the progressive weakening of a quasiparticle peak at the Fermi level (E-F) occurs below 10 monolayer (ML), and the further depletion of spectral weight at E-F leads to pseudogap behavior at 3-6 ML. The pseudogap finally evolves into a full gap, indicating that the thickness-dependent MIT takes place at a critical film thickness of 2-3 ML. The observed spectral behavior is in line with the transport properties of LNO ultrathin films. The thickness dependence of the spectral intensity is compared with realistic multiorbital dynamical mean-field theory. The experimental spectral function was found to depend on the film thickness more strongly than the theoretical one for thinner systems, indicating that the thickness-dependent MIT in LNO is caused by the crossover from three to two dimensions, during which the spatial correlations are progressively enhanced. The XAS results suggest that a charge disproportionate state is strongly suppressed in LNO ultrathin films plausibly as a result of epitaxial strain from the substrates. These results strongly suggest that a novel insulating state is realized in LNO films at a thin limit.

CA CLAS Collaboration TI Separated structure functions for exclusive K+Lambda and K+Sigma(0) electroproduction at 5.5 GeV measured with CLAS SO PHYSICAL REVIEW C LA English DT Article ID BARYON RESONANCES; PHOTON ENERGIES; LAMBDA; K+; PHOTOPRODUCTION; POLARIZATION; SIGMA(0); SYSTEM; PION AB We report measurements of the exclusive electroproduction of K+Lambda and K+Sigma(0) final states from an unpolarized proton target using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The separated structure functions sigma(U), sigma(LT), sigma(T) T, and sigma(LT') were extracted from the Phi-dependent differential cross sections acquired with a longitudinally polarized 5.499 GeV electron beam. The data span a broad range of momentum transfers Q(2) from 1.4 to 3.9GeV(2), invariant energy W from threshold to 2.6GeV, and nearly the full center-of-mass angular range of the kaon. The separated structure functions provide an unprecedented data sample, which, in conjunction with other meson photo-and electroproduction data, will help to constrain the higher-level analyses being performed to search for missing baryon resonances.

TI Multiple band structures in Re-169,Re-170: Search for the wobbling mode in Re-169, and residual-interaction analysis of structures in Re-170 SO PHYSICAL REVIEW C LA English DT Article ID HIGH-SPIN STRUCTURE; COINCIDENCE DATA; BETA-DECAY; EXCITATIONS; NUCLEI; CONFIGURATION; ISOTOPES; LU-165; PHONON AB Although the observation of wobbling was once thought to be possibly confined to lutetium isotopes in N approximate to 94 nuclei, the identification of this exotic collective mode in Ta-167 has raised the question of the role of the proton Fermi surface with regard to this phenomenon. To investigate this issue, an experiment was performed to populate high-spin states in the N = 94 nucleus Re-169. The heavy-ion reaction Mn-55 + Sn-118 was used in conjunction with Gammasphere to detect the emitted gamma rays. More than 130 new transitions were added to the Re-169 level scheme, including the first identification of the pi i(13/2) rotational sequence in this nucleus. This configuration is the structure on which all known wobbling sequences are based, but no wobbling band was observed, likely owing to the fact that the pi i(13/2) sequence is located at a relatively high energy in comparison with the other structures found in Re-169. Nine decay sequences are now established in this nucleus and are described within the context of the cranked shell model. In addition, significant extension of the level scheme of the odd-odd Re-170 nucleus was possible and a discussion of the residual interactions for the pi h(9/2)nu i(13/2) and pi i(13/2)nu i(13/2) configurations in this region is given as well.

TI High intensity neutrino oscillation facilities in Europe SO PHYSICAL REVIEW SPECIAL TOPICS-ACCELERATORS AND BEAMS LA English DT Article ID BETA-BEAM; EMMA AB The EUROnu project has studied three possible options for future, high intensity neutrino oscillation facilities in Europe. The first is a Super Beam, in which the neutrinos come from the decay of pions created by bombarding targets with a 4 MW proton beam from the CERN High Power Superconducting Proton Linac. The far detector for this facility is the 500 kt MEMPHYS water Cherenkov, located in the Frejus tunnel. The second facility is the Neutrino Factory, in which the neutrinos come from the decay of mu(+) and mu(-) beams in a storage ring. The far detector in this case is a 100 kt magnetized iron neutrino detector at a baseline of 2000 km. The third option is a Beta Beam, in which the neutrinos come from the decay of beta emitting isotopes, in particular He-6 and Ne-18, also stored in a ring. The far detector is also the MEMPHYS detector in the Frejus tunnel. EUROnu has undertaken conceptual designs of these facilities and studied the performance of the detectors. Based on this, it has determined the physics reach of each facility, in particular for the measurement of CP violation in the lepton sector, and estimated the cost of construction. These have demonstrated that the best facility to build is the Neutrino Factory. However, if a powerful proton driver is constructed for another purpose or if the MEMPHYS detector is built for astroparticle physics, the Super Beam also becomes very attractive.

TI Orientation of Phenylphosphonic Acid Self-Assembled Monolayers on a Transparent Conductive Oxide: A Combined NEXAFS, PM-IRRAS, and DFT Study SO LANGMUIR LA English DT Article ID INDIUM-TIN OXIDE; ABSORPTION FINE-STRUCTURE; TOTAL-ENERGY CALCULATIONS; LANGMUIR-BLODGETT-FILMS; POLYMER SOLAR-CELLS; WAVE BASIS-SET; WORK FUNCTION; STRUCTURAL-CHARACTERIZATION; PHENYLTHIOPHOSPHONIC ACID; BENZYLPHOSPHONIC ACIDS AB Self-assembled monolayers (SAMs) of dipolar phosphonic acids can tailor the interface between organic semiconductors and transparent conductive oxides. When used in optoelectronic devices such as organic light emitting diodes and solar cells, these SAMs can increase current density and photovoltaic performance. The molecular ordering and conformation adopted by the SAMs determine properties such as work function and wettability at these critical interfaces. We combine angle-dependent near-edge X-ray absorption fine structure (NEXAFS) spectroscopy and polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS) to determine the molecular orientations of a model phenylphosphonic acid on indium zinc oxide, and correlate the resulting values with density functional theory (DFT). We find that the SAMs are surprisingly well-oriented, with the phenyl ring adopting a well-defined tilt angle of 12-16 degrees from the surface normal. We find quantitative agreement between the two experimental techniques and density functional theory calculations. These results not only provide a detailed picture of the molecular structure of a technologically important class of SAMs, but also resolve a long-standing ambiguity regarding the vibrational-mode assignments for phosphonic acids on oxide surfaces, thus improving the utility of PM-IRRAS for future studies.

TI Layer-by-Layer Templated Assembly of Silica at the Nanoscale SO LANGMUIR LA English DT Article ID BIOMIMETIC SYNTHESIS; BIOSILICA; PEPTIDES; FILMS; SILICIFICATION; COATINGS; DIVERSE; PROTEIN; PART AB Bioinspired bottom-up assembly and layer-by-layer (LbL) construction of inorganic materials from lithographically defined organic templates enables the fabrication of nanostructured systems under mild temperature and pH conditions. Such processes open the door to low-impact manufacturing and facile recycling of hybrid materials for energy, biology, and information technologies. Here, templated LbL assembly of silica was achieved using a combination of electron beam lithography, chemical lift-off, and aqueous solution chemistry. Nanopatterns of lines, honeycomb-lattices, and dot arrays were defined in polymer resist using electron beam lithography. Following development, exposed areas of silicon were functionalized with a vapor deposited amine-silane monolayer. Silicic acid solutions of varying pH and salt content were reacted with the patterned organic amine-functional templates. Vapor treatment and solution reaction could be repeated, allowing LbL deposition. Conditions for the silicic acid deposition had a strong effect on thickness of each layer, and the morphology of the amorphous silica formed. "Defects" in the arrays of silica nanostructures were minor and do not affect the overall organization of the layers. The bioinspired method described here facilitates the bottom-up assembly of inorganic nanostructures defined in three dimensions and provides a path, via LbL processing, for the construction of layered hybrid materials under mild conditions.

TI Resonance Raman and temperature-dependent electronic absorption spectra of cavity and noncavity models of the hydrated electron SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE solvated electron; quantum simulation; Raman spectroscopy; optical spectroscopy ID AQUEOUS SOLVATED ELECTRON; DILUTE HOD; MOLECULAR-DYNAMICS; LIQUID H2O; WATER; SPECTROSCOPY; SIMULATION; D2O; CLUSTERS AB Most of what is known about the structure of the hydrated electron comes from mixed quantum/classical simulations, which depend on the pseudopotential that couples the quantum electron to the classical water molecules. These potentials usually are highly repulsive, producing cavity-bound hydrated electrons that break the local water H-bonding structure. However, we recently developed a more attractive potential, which produces a hydrated electron that encompasses a region of enhanced water density. Both our noncavity and the various cavity models predict similar experimental observables. In this paper, we work to distinguish between these models by studying both the temperature dependence of the optical absorption spectrum, which provides insight into the balance of the attractive and repulsive terms in the potential, and the resonance Raman spectrum, which provides a direct measure of the local H-bonding environment near the electron. We find that only our noncavity model can capture the experimental red shift of the hydrated electron's absorption spectrum with increasing temperature at constant density. Cavity models of the hydrated electron predict a solvation structure similar to that of the larger aqueous halides, leading to a Raman O-H stretching band that is blue-shifted and narrower than that of bulk water. In contrast, experiments show the hydrated electron has a broader and red-shifted O-H stretching band compared with bulk water, a feature recovered by our noncavity model. We conclude that although our noncavity model does not provide perfect quantitative agreement with experiment, the hydrated electron must have a significant degree of noncavity character.

The importance of many-body interactions that renormalize the linear bands near Dirac point in graphene has been well recognized and attracted much recent attention. However, renormalization of the helical Dirac point has not been observed in topological insulators. Here, we report the experimental observation of the renormalized quasi-particle spectrum with a skewed Dirac cone in a single Bi bilayer grown on Bi2Te3 substrate from angle-resolved photoemission spectroscopy. First-principles band calculations indicate that the quasi-particle spectra are likely associated with the hybridization between the extrinsic substrate-induced Dirac states of Bi bilayer and the intrinsic surface Dirac states of Bi2Se3 film at close energy proximity. Without such hybridization, only single-particle Dirac spectra are observed in a single Bi bilayer grown on Bi2Se3, where the extrinsic Dirac states Bi bilayer and the intrinsic Dirac states of Bi2Se3 are well separated in energy. The possible origins of many-body interactions are discussed. Our findings provide a means to manipulate topological surface states. C1 [Miao, Lin; Yao, Meng-Yu; Wang, Meixiao; Yang, Fang; Song, Y.

A cyanobacterial pathway consisting of acyl-Acyl Carrier Protein reductase and an aldehyde-deformylating oxygenase (ADO) converts acyl-Acyl Carrier Proteins into corresponding n-1 alkanes via aldehyde intermediates in an oxygen-dependent manner (K-m for O-2, 84 +/- 9 mu M). In vitro, ADO turned over only three times, but addition of more ADO to exhausted assays resulted in additional product formation. While evaluating the peroxide shunt to drive ADO catalysis, we discovered that ADO is inhibited by hydrogen peroxide (H2O2) with an apparent K-i of 16 +/- 6 mu M and that H2O2 inhibition is of mixed-type with respect to O-2. Supplementing exhausted assays with catalase (CAT) restored ADO activity, demonstrating that inhibition was reversible and dependent on H2O2, which originated from poor coupling of reductant consumption with alkane formation. Kinetic analysis showed that long-chain (C14-C18) substrates follow Michaelis-Menten kinetics, whereas short and medium chains (C8-C12) exhibit substrate inhibition. A bifunctional protein comprising an N-terminal CAT coupled to a C-terminal ADO (CAT-ADO) prevents H2O2 inhibition by converting it to the cosubstrate O-2. Indeed, alkane production by the fusion protein is observed upon addition of H2O2 to an anaerobic reaction mix. In assays, CAT-ADO turns over 225 times versus three times for the native ADO, and its expression in Escherichia coli increases catalytic turnovers per active site by fivefold relative to the expression of native ADO. We propose the term "protection via inhibitor metabolism" for fusion proteins designed to metabolize inhibitors into noninhibitory compounds.

TI Direct chemical evidence for sphingolipid domains in the plasma membranes of fibroblasts SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE SIMS; stable isotope ID ION MASS-SPECTROMETRY; GPI-ANCHORED PROTEINS; CELL-MEMBRANE; LIPID RAFTS; INFLUENZA-VIRUS; CHOLESTEROL; SURFACE; ACTIN; ORGANIZATION; MOLECULES AB Sphingolipids play important roles in plasma membrane structure and cell signaling. However, their lateral distribution in the plasma membrane is poorly understood. Here we quantitatively analyzed the sphingolipid organization on the entire dorsal surface of intact cells by mapping the distribution of N-15-enriched ions from metabolically labeled N-15-sphingolipids in the plasma membrane, using high-resolution imaging mass spectrometry. Many types of control experiments (internal, positive, negative, and fixation temperature), along with parallel experiments involving the imaging of fluorescent sphingolipids-both in living cells and during fixation of living cells-exclude potential artifacts. Micrometer-scale sphingolipid patches consisting of numerous N-15-sphingolipid microdomains with mean diameters of similar to 200 nm are always present in the plasma membrane. Depletion of 30% of the cellular cholesterol did not eliminate the sphingolipid domains, but did reduce their abundance and long-range organization in the plasma membrane. In contrast, disruption of the cytoskeleton eliminated the sphingolipid domains. These results indicate that these sphingolipid assemblages are not lipid rafts and are instead a distinctly different type of sphingolipid-enriched plasma membrane domain that depends upon cortical actin.

A compact high-pressure cryogenic storage system has promising features to the storage challenge associated with hydrogen-powered vehicles. Cryogenic pressure vessels consist of an inner vessel designed for high pressure (350 bar) insulated with reflective sheets of metalized plastic and enclosed within an outer metallic vacuum jacket. When filled with pressurized liquid hydrogen, cryogenic pressure vessels become the most compact form of hydrogen storage available. A recent prototype is the only automotive hydrogen vessel meeting both Department of Energy's 2017 weight and volume targets. When installed onboard an experimental vehicle, a cryogenic pressure vessel demonstrated the longest driving distance with a single H-2 tank (1050 km). In a subsequent experiment, the vessel demonstrated unprecedented thermal endurance: 8 days parking with no evaporative losses, extending to a month if the vehicle is driven as little as 8 km per day. Calculations indicate that cryogenic vessels offer compelling safety advantages and the lowest total ownership cost of hydrogen storage technologies. Long-term (similar to 10 years) vacuum stability (necessary for high performance thermal insulation) is the key outstanding technical challenge. Testing continues to establish technical feasibility and safety. Copyright (C) 2012, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.

TI Setting a best practice for determining the EGR rate in hydrogen internal combustion engines SO INTERNATIONAL JOURNAL OF HYDROGEN ENERGY LA English DT Article DE Internal combustion engine; Hydrogen; EGR measurement; Error analysis ID EXHAUST-GAS RECIRCULATION AB Exhaust gas recirculation (EGR) is an effective way to reduce NOx-emissions and increase the efficiency of hydrogen fueled internal combustion engines. Knowledge of the exact amount of EGR is crucial to understand the effects of EGR. As the exhaust gas flow is pulsating and chemically aggressive, the flow rate is typically not measured directly and has to be derived from other quantities. For hydrocarbon fuels, the EGR rate is generally calculated from a molar CO2 balance, but for hydrogen engines this obviously cannot be used as there are no CO2 emissions, and consequently no standard practice has been established. This work considers three methods to calculate the amount of EGR in a hydrogen engine. The first one is based upon a volume balance in the mixing section of exhaust gases and fresh air. The second and third method uses a molar balance of O-2 and H2O respectively in this mixing section. The three methods are developed and tested for their accuracy with an error analysis. Additionally, the methods are applied to an experimental dataset gathered on a single cylinder hydrogen engine. Both the theoretical analysis and the experimental results confirm the method based on an O-2 molar balance as the most accurate one. The least practical method is the one based on an H2O balance as it requires additional relative humidity sensors and is less accurate than the others.

By introducing a stream of particles in between the DART ionization source and the atmospheric pressure inlet of the mass spectrometer, the aerosol is exposed to a thermal flow of helium or nitrogen gas containing some fraction of metastable helium atoms or nitrogen molecules. In this configuration, the molecular constituents of organic particles are desorbed, ionized, and detected with reduced molecular ion fragmentation, allowing for compositional identification. Aerosol particles detected include alkanes, alkenes, acids, esters, alcohols, aldehydes, and amino acids. The ion signal produced by DART-MS scales with the aerosol surface area rather than volume, suggesting that DART-MS is a viable technique to measure the chemical composition of the particle interface. For oleic acid, particle size measurements of the aerosol stream exiting the ionization region suggest that the probing depth depends upon the desorption temperature, and the probing depth is estimated to be on the order of 5 nm for a 185 nm diameter particle at a DART heater temperature of 500 degrees C with nitrogen as the DART gas. The reaction of ozone with submicrometer oleic acid particles is measured to demonstrate the ability of this technique to identify products and quantify reaction rates in a heterogeneous reaction.

The main steps in metabolite sample preparation include quenching and metabolite extraction. Quenching with 60% (v/v) cold methanol at -40 degrees C has been most commonly used for Saccharomyces cerevisiae, and this method was recently modified as "leakage-free cold methanol quenching" using pure methanol at -40 degrees C. Boiling ethanol (75%, v/v) and cold pure methanol are the most widely used extraction solvents for S. cerevisiae. In the present study, metabolome sampling protocols, including the above methods, were evaluated by analyzing 110 identified intracellular metabolites of S. cerevisiae using gas chromatography/time-of-flight mass spectrometry. According to our results, fast filtration followed by washing with an appropriate volume of water can minimize the metabolite loss due to cell leakage as well as the contamination by extracellular metabolites, For metabolite extraction, acetonitrile/water mixture (1:1, v/v) at -20 degrees C was the most effective. These results imply that the systematic evaluation of existing methods and the development of customized methods for each microorganism are critical for metabolome sample preparation to facilitate the reliable and accurate analysis of metabolome.

TI Elastomeric Negative Acoustic Contrast Particles for Affinity Capture Assays SO ANALYTICAL CHEMISTRY LA English DT Article ID FLOW-CYTOMETRY; MASS-SPECTROMETRY; STANDING WAVES; WHOLE-BLOOD; SEPARATION; PROTEIN; CHIP; ULTRAFILTRATION; DISCOVERY; CHANNELS AB This report describes the development of elastomeric capture microparticles (EC mu Ps) and their use with acoustophoretic separation to perform microparticle assays via flow cytometry. We have developed simple methods to form EC mu Ps by cross-linking droplets of common commercially available silicone precursors in suspension followed by surface functionalization with biomolecular recognition reagents. The EC mu Ps are compressible particles that exhibit negative acoustic contrast in ultrasound when suspended in aqueous media, blood serum, or diluted blood. In this study, these particles have been functionalized with antibodies to bind prostate specific antigen and immunoglobulin (IgG). Specific separation of the EC mu Ps from blood cells is achieved by flowing them through a microfluidic acoustophoretic device that uses an ultrasonic standing wave to align the blood cells, which exhibit positive acoustic contrast, at a node in the acoustic pressure distribution while aligning the negative acoustic contrast EC mu Ps at the antinodes. Laminar flow of the separated particles to downstream collection ports allows for collection of the separated negative contrast (EC mu Ps) and positive contrast particles (cells). Separated EC mu Ps were analyzed via flow cytometry to demonstrate nanomolar detection for prostate specific antigen in aqueous buffer and picomolar detection for IgG in plasma and diluted blood samples. This approach has potential applications in the development of rapid assays that detect the presence of low concentrations of biomarkers in a number of biological sample types.

First, scattering patterns are measured at different protein and ligand concentrations. Multivariate curve resolution based on singular value decomposition and global analysis is applied to estimate the binding affinities and reference patterns (i.e., the scattering patterns of individual components). As validated by simulation, Bayesian confidence intervals provide accurate uncertainty estimates for the binding free energies and reference patterns. Experimental results from several protein-ligand systems demonstrate the feasibility of the approach, which promises to expand the role of wide-angle x-ray scattering as a quantitative biophysical tool.

Here, we conduct molecular dynamics simulations and free energy calculations to examine the initial binding of a cellulose chain into the catalytic tunnel of the reducing-end-specific Family 7 cellobiohydrolase (Cel7A) from Hypocrea jecorina. In unrestrained simulations, the cellulose diffuses into the tunnel from the 7 to the 5 positions, and the associated free energy profiles exhibit no barriers for initial processivity. The comparison of the free energy profiles for different cellulose chain orientations show a thermodynamic preference for the reducing end, suggesting that the preferential initial binding may affect the directional specificity of the enzyme by impeding nonproductive (nonreducing end) binding. Finally, the Trp-40 at the tunnel entrance is shown with free energy calculations to have a significant effect on initial chain complexation in Cel7A.

TI Prepairing and the "filling" gap in the cuprates from the tomographic density of states SO PHYSICAL REVIEW B LA English DT Article ID SCANNING-TUNNELING-MICROSCOPY; TRANSITION-TEMPERATURE; PSEUDOGAP STATE; SUPERCONDUCTORS; BI2SR2CACU2O8+DELTA; ORIGIN; SPECTROSCOPY; BREAKING AB We use the tomographic density of states (TDOS), which is a measure of the density of states for a single slice through the band structure of a solid, to study the temperature evolution of the superconducting gap in the cuprates. The TDOS provides accuracy in determining both the superconducting pair-forming strength Delta and the pair-breaking rate Gamma. In both optimally and underdoped Bi2Sr2CaCu2O8+delta, we find the near-nodal Delta smoothly evolves through the superconducting transition temperature-clear evidence for the existence of preformed pairs. Additionally, we find the long-observed "filling" of the superconducting gap in the cuprates is due to the strongly temperature-dependent Gamma. DOI: 10.1103/PhysRevB.87.060506 C1 [Reber, T.

TI Free-carrier relaxation and lattice heating in photoexcited bismuth SO PHYSICAL REVIEW B LA English DT Article ID METALS; ELECTRONS; SCATTERING; MOBILITY; GAAS; SB; BI AB We report ultrafast surface pump and interface probe experiments on photoexcited carrier transport across single crystal bismuth films on sapphire. The film thickness is sufficient to separate carrier dynamics from lattice heating and strain, allowing us to investigate the time scales of momentum relaxation, heat transfer to the lattice, and electron-hole recombination. The measured electron-hole (e - h) recombination time is 12-26 ps and ambipolar diffusivity is 18-40 cm(2)/s for carrier excitation up to similar to 10(19) cm(-3). By comparing the heating of the front and back sides of the film, we put lower limits on the rate of heat transfer to the lattice, and by observing the decay of the plasma at the back of the film, we estimate the time scale of electron-hole recombination. We interpret each of these time scales within a common framework of electron-phonon scattering and find qualitative agreement between the various relaxation times observed. We find that the carrier density is not determined by the e - h plasma temperature after a few picoseconds. The diffusion and recombination become nonlinear with initial excitation greater than or similar to 10(20) cm(-3). DOI: 10.1103/PhysRevB.87.075429 C1 [Sheu, Y.

TI Lifshitz Gravity for Lifshitz Holography SO PHYSICAL REVIEW LETTERS LA English DT Article ID RENORMALIZATION-GROUP AB We argue that Horava-Lifshitz (HL) gravity provides the minimal holographic dual for Lifshitz-type field theories with anisotropic scaling and a dynamical exponent z. First we show that Lifshitz spacetimes are vacuum solutions of HL gravity, without need for additional matter. Then we perform holographic renormalization of HL gravity, and show how it reproduces the full structure of the z = 2 anisotropic Weyl anomaly in dual field theories in 2 + 1 dimensions, while its minimal relativistic gravity counterpart yields only one of two independent central charges in the anomaly.

By using first-principles based cluster expansion, we find that the existence of phase separation in conventional GOs is due to the extremely strong attractive interactions of oxygen atoms at different graphene sides. Our Monte Carlo simulations show that this kind of phase separation is not avoidable under the current experimental growth temperature. In this Letter, the idea of oxidizing graphene on a single side is proposed to eliminate the strong double-side oxygen attractions, and our calculations show that well-ordered GOs could be obtained at low oxygen concentrations. These ordered GOs behave as quasi-one-dimensional narrow-gap semiconductors with quite small electron effective masses, which can be useful in high-speed electronics. Our concept could be widely applied to overcome the phase inhomogeneity in various chemically functionalized two-dimensional systems.

Using multiscale modeling, we show that a different class of He precipitates may form at semicoherent interfaces: nanoscale platelets. These platelets grow by wetting high-energy interface regions, remain stable under irradiation, and reduce He-induced swelling. Stable storage of He at interfaces may impart unprecedented He resistance to future structural materials. DOI: 10.1103/PhysRevLett.110.086101 C1 [Kashinath, A.; Demkowicz, M.

TI Spectroscopy of F-26 to Probe Proton-Neutron Forces Close to the Drip Line SO PHYSICAL REVIEW LETTERS LA English DT Article ID NUCLEAR; SPECTROMETER; CLOSURES; DECAY; MASS; N=20 AB A long-lived J(pi) = 4(1)(+) isomer, T-1/2 = 2.2(1) ms, has been discovered at 643.4(1) keV in the weakly bound F-26(9) nucleus. It was populated at Grand Accelerateur National d'Ions Lourds in the fragmentation of a S-36 beam. It decays by an internal transition to the J(pi) = 1(1)(+) ground state [82(14)%], by beta decay to Ne-26, or beta-delayed neutron emission to Ne-25. From the beta-decay studies of the J(pi) = 1(1)(+) and J(pi) = 4(1)(+) states, new excited states have been discovered in Ne-25,Ne-26. Gathering the measured binding energies of the J(pi) = 1(1)(+) - 4(1)(+) multiplet in F-26(9), we find that the proton-neutron pi 0d(5/2) nu 0d(3/2) effective force used in shell-model calculations should be reduced to properly account for the weak binding of F-26(9). Microscopic coupled cluster theory calculations using interactions derived from chiral effective field theory are in very good agreement with the energy of the low-lying 1(1)(+), 2(1)(+), 4(1)(+) states in F-26. Including three-body forces and coupling to the continuum effects improve the agreement between experiment and theory as compared to the use of two-body forces only.

The corresponding differential cross section is evaluated as a convolution of a twist-three quark-gluon correlation function, often referred to as Qiu-Sterman function, the usual unpolarized fragmentation function, and a hard coefficient function. By studying the collinear divergence structure, we identify the evolution kernel for the Qiu-Sterman function. The hard coefficient function, which is finite and free of any divergence, is evaluated at one-loop order.

TI Quantitative x-ray phase imaging at the nanoscale by multilayer Laue lenses SO SCIENTIFIC REPORTS LA English DT Article ID TEM SPECIMEN PREPARATION; ANODE; MICROSCOPY; CONTRAST AB For scanning x-ray microscopy, many attempts have been made to image the phase contrast based on a concept of the beam being deflected by a specimen, the so-called differential phase contrast imaging (DPC). Despite the successful demonstration in a number of representative cases at moderate spatial resolutions, these methods suffer from various limitations that preclude applications of DPC for ultra-high spatial resolution imaging, where the emerging wave field from the focusing optic tends to be significantly more complicated. In this work, we propose a highly robust and generic approach based on a Fourier-shift fitting process and demonstrate quantitative phase imaging of a solid oxide fuel cell (SOFC) anode by multilayer Laue lenses (MLLs). The high sensitivity of the phase to structural and compositional variations makes our technique extremely powerful in correlating the electrode performance with its buried nanoscale interfacial structures that may be invisible to the absorption and fluorescence contrasts.

Communities from a total of four manipulated microcosms were analyzed, supplied with C-13-methane in, respectively, ambient air, ambient air with the addition of nitrate, nitrogen atmosphere and nitrogen atmosphere with the addition of nitrate, and these were compared to the community from an unamended sediment sample. We found that the major group involved in methane oxidation in both aerobic and microaerobic conditions were members of the family Methylococcaceae, dominated by species of the genus Methylobacter, and these were stimulated by nitrate in aerobic but not microaerobic conditions. In aerobic conditions, we also noted a pronounced response to both methane and nitrate by members of the family Methylophilaceae that are non-methane-oxidizing methylotrophs, and predominantly by the members of the genus Methylotenera. The relevant abundances of the Methylococcaceae and the Methylophilaceae and their coordinated response to methane and nitrate suggest that these species may be engaged in cooperative behavior, the nature of which remains unknown.

This is an essential input for machine performance characterization and for the design of collimation systems. Beam halo measurements in the CERN Large Hadron Collider were conducted through collimator scrapings in a dedicated beam study for the first time at 4 TeV. Four scans were performed with two collimators, in the vertical plane for beam 1 and horizontally for beam 2, before and after bringing the beams into collisions. Inward and outward steps were performed. A diffusion model was used to interpret the observed loss rate evolution in response to the collimator steps. With this technique, diffusion coefficients were estimated as a function of betatron oscillation amplitude from approximately 3 to 7 standard deviations of the transverse beam distribution. A comparison of halo diffusion and core emittance growth rates is also presented.

Here, we experimentally demonstrated the resonant amplification of vortex oscillations by application of simple coherent field pulses tuned to optimal width and time intervals. In order to investigate vortex excitations on the sub-ns time scale, we employed state-of-the-art time-resolved full-field soft X-ray microscopy of 70 ps temporal and 25 nm lateral resolution. We found that, due to the resonant enhancement of the vortex gyration motion, the signal input power can be significantly reduced to similar to 1 Oe in field strength, while increasing signal gains, by increasing the number of the optimal field pulses. We identified the origin of this behavior as the forced resonant amplification of vortex gyration. This work represents an important milestone towards the potential implementation of vortex oscillations in future magnetic vortex devices.

TI Comparison of CsBr and KBr covered Cu photocathodes: Effects of laser irradiation and work function changes SO APPLIED PHYSICS LETTERS LA English DT Article AB Thin films of CsBr and KBr were deposited on Cu(100) to investigate photoemission properties of these potential photocathode materials. After prolonged laser ultraviolet irradiation photoemission, quantum efficiency increases by factors of 26 and 77 for KBr/Cu(100) and CsBr/Cu(100) photocathodes, respectively. Immediately following thin film deposition, a decrease in work function is observed, compared to bare Cu, in both cases. Quantum efficiency enhancements are attributed to the decrease in photocathode work function, and photo-induced processes that introduce defect states into the alkali halide bandgap. Our results suggest that KBr, a relatively stable alkali-halide, also has potential for photocathode applications. (C) 2013 American Institute of Physics.

By exploiting thin film epitaxy, which provides controlled biaxial stress to create lattice distortion, we demonstrate that giant magnetism can be established in Fe16N2 thin film coherently grown on MgO (001) substrate. Explored by polarized neutron reflectometry, the depth-dependent saturation magnetic induction (Bs) of epitaxial Fe16N2 thin films is visualized, which reveals a strong correlation with the in-plane lattice parameter and tensile strain developed at near substrate interface. With controlled growth process and dimension adjustment, the Bs of these films can be modulated over a broad range, from similar to 2.1 Tesla (T) (normal Bs) up to similar to 3.1 T (giant Bs).

Their ferroelectric and dielectric properties were measured as a function of temperature. With increasing temperature from room temperature to 200 degrees C, back-switching polarization increased while spontaneous polarization, remanent polarization, and coercive field decreased. The domain wall energy barrier was determined from the temperature-dependent back-switching polarization. Decreased irreversible/extrinsic and reversible/intrinsic dielectric responses were observed with increasing frequency. The ratio of irreversible to reversible contributions to dielectric nonlinearity was analyzed by the Rayleigh law. This ratio decreased with increasing frequency from 500 Hz to 500 kHz.

Here we describe a structure at the ciliary base that appears to have all the features required for compartmentalization and which we thus call the "ciliary partitioning system" (CPS). This complex consists of the terminal plate, which serves as a cytosolic "ciliary pore complex" (CPC), and a membrane region well suited to serve as a diffusion barrier. The CPC is a plate-shaped structure containing nine pores through which the microtubule doublets of the basal body pass. Each pore expands from the doublet B-tubule into an opening well suited for the passage of intraflagellar transport particles. The membrane diffusion barrier encompasses an extended region of detergent-resistant periciliary membrane (ciliary pocket) and a ring complex that connects the CPC to the membrane. Proteomics analysis shows involvement of the ciliary pocket in vesicle trafficking, suggesting that this region plays an active role in membrane transport. The CPC and the ring together form a complete partition defining the ciliary boundary.

The solid-state, amorphous iridium oxide material that is formed from the molecular precursors is significantly more active for water-oxidation catalysis than crystalline IrO2 and functions as a remarkably robust catalyst, capable of catalyzing water oxidation without deactivation or significant corrosion for at least 70 h. Elemental analysis reveals that BL contains carbon that is derived from the Cp* ligand (similar to 3% by mass after prolonged electrolysis). Because the electrodeposition of precursors 1 or 2 gives a highly active catalyst material, and electrochemical oxidation of other iridium complexes seems not to result in immediate conversion to iridium oxide materials, we investigate here the nature of the deposited material. The steps leading to the formation of BL and its structure have been investigated by a combination of spectroscopic and theoretical methods. IR spectroscopy shows that the carbon content of BL, while containing some C H bonds intact at short times, is composed primarily of components with C=O fragments at longer times. X-ray absorption and X-ray absorption fine structure show that, on average, the six ligands to iridium in. BL are likely oxygen atoms, consistent with formation of iridium oxide under the oxidizing conditions. High-energy X-ray scattering (HEXS) and pair distribution function (PDF) analysis (obtained ex situ on powder samples) show that BL is largely free of the molecular precursors and is composed of small, <7 angstrom, iridium oxide domains. Density functional theory (DFT) modeling of the X-ray data suggests a limited set of final components in BL; ketomalonate has been chosen as a model fragment because it gives a good fit to the HEXS-PDF data and is a potential decomposition product of Cp*.

All of the materials are triclinic, with space group P (1) over bar. The three-dimensional structure of these isostructural uranates consists of oxalate bridged UO10 and MO6 polyhedra. The U4+ cation is surrounded by five oxalate ligands, while the M2+ cations are bonded to two oxalate ligands and four water molecules. The magnetic susceptibility data of these mixed metal oxalates were measured as a function of temperature and result in a value of the effective magnetic moment of 3.50 mu(B) for U4+ cation in the Zn member, while the total effective moment of the Mn2+, Fe2+, and Co2+ members are 6.01, 5.46, and 5.06 mu(B), respectively. For all materials, negative Weiss constants were observed revealing that the materials exhibited local antiferromagnetic interactions. The U4+ cation exhibits a singlet ground state at low temperature. The materials were further characterized by infrared, UV-vis reflectance spectroscopy, and thermal analysis.

J. Blume-Kohout, Robin TI When quantum tomography goes wrong: drift of quantum sources and other errors SO NEW JOURNAL OF PHYSICS LA English DT Article AB The principle behind quantum tomography is that a large set of observations-many samples from a 'quorum' of distinct observables-can all be explained satisfactorily as measurements on a single underlying quantum state or process. Unfortunately, this principle may not hold. When it fails, any standard tomographic estimate should be viewed skeptically. Here we propose a simple way to test for this kind of failure using the Akaike information criterion. We point out that the application of this criterion in a quantum context, while still powerful, is not as straightforward as it is in classical physics. This is especially the case when future observables differ from those constituting the quorum. C1 [van Enk, S. J.] Univ Oregon, Dept Phys, Eugene, OR 97403 USA. [van Enk, S.

TI Surface waves and electron acceleration from high-power, kilojoule-class laser interactions with underdense plasma SO NEW JOURNAL OF PHYSICS LA English DT Article ID CHANNEL FORMATION; BEAMS; PULSE; GENERATION AB Experiments were performed on the Omega EP laser facility to study laser pulse propagation, channeling phenomena and electron acceleration from high-intensity, high-power laser interactions with underdense plasma. A CH plasma plume was used as the underdense target and the interaction of the laser pulse channeling through the plasma was imaged using proton radiography. High-energy electron spectra were measured for different experimental laser parameters. Structures observed along the channel walls are interpreted as having developed from surface waves, which are likely to serve as an injection mechanism of electrons into the cavitated channel for acceleration via direct laser acceleration mechanisms. Two-dimensional particle-in-cell simulations give good agreement with these channeling and electron acceleration phenomena. C1 [Willingale, L.; Thomas, A. G.

Data analysis was performed on the whole-pattern base. P B copolymer was stretched at three temperatures, i.e., 100 degrees C, 60 degrees C and 25 degrees C. Before stretching, the static sample contained both gamma- and alpha-phase of isotactic polypropylene (iPP) homopolymer, with the gamma-phase being the dominant crystal modification. When subjected to uniaxial stretching, gamma-phase adopted a tilted cross-beta configuration, with the c-axis forming a tilting angle with respect to the fiber axis at all temperatures. At 100 degrees C and 60 degrees C, gamma-phase was transformed to alpha-phase with parallel orientation of polymer chains. Daughter lamellae of the alpha-phase were observed at 100 degrees C but not at 60 degrees C. At room temperature, large lamellar crystals could not be formed due to strong tensile force applied to the polymer network. Low temperature stretching was featured with the formation of mesomorphic phase which was composed of tiny beta-form crystals and of about 50% of oriented amorphous phase. The c-axis of the beta-form crystal was in parallel to the fiber axis. The crystals were so small that no ordered texture was observed at the length scale of nanometers. (C) 2012 Elsevier Ltd.

The climate forcing evaluated this way, termed the adjusted forcing (AF), includes a rapid adjustment term associated with cloud changes and other tropospheric and land-surface changes. We estimate a 2010 total anthropogenic and natural AF from CMIP5 models of 1.9 +/- 0.9 W m(-2) (5-95% range). The projected AF of the Representative Concentration Pathway simulations are lower than their expected radiative forcing (RF) in 2095 but agree well with efficacy weighted forcings from integrated assessment models. The smaller AF, compared to RF, is likely due to cloud adjustment. Multimodel time series of temperature change and AF from 1850 to 2100 have large intermodel spreads throughout the period. The intermodel spread of temperature change is principally driven by forcing differences in the present day and climate feedback differences in 2095, although forcing differences are still important for model spread at 2095. We find no significant relationship between the equilibrium climate sensitivity (ECS) of a model and its 2003 AF, in contrast to that found in older models where higher ECS models generally had less forcing. Given the large present-day model spread, there is no indication of any tendency by modelling groups to adjust their aerosol forcing in order to produce observed trends. Instead, some CMIP5 models have a relatively large positive forcing and overestimate the observed temperature change.

In more recent models, there is widespread reduction of a bias associated with too many highly reflective clouds, with the best models having eliminated this bias. With increased amounts of clouds with lesser reflectivity, the compensating errors that permit models to simulate the time-mean radiation balance have been reduced. Errors in cloud amount as a function of height or climate regime on average show little or no improvement, although greater improvement can be found in individual models.

TI Modeling aerosols and their interactions with shallow cumuli during the 2007 CHAPS field study SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article ID SECONDARY ORGANIC AEROSOL; CLOUD-CONDENSATION-NUCLEI; MEXICO-CITY EMISSIONS; BASIS-SET APPROACH; MINERAL-DUST; WRF-CHEM; CONVECTIVE PARAMETERIZATION; SIZE DISTRIBUTIONS; OPTICAL-PROPERTIES; REFRACTIVE-INDEX AB The Weather Research and Forecasting model coupled with chemistry, using 2 km horizontal grid spacing, is used to simulate two important relationships between aerosols and clouds in the vicinity of Oklahoma City during the June 2007 Cumulus Humilis Aerosol Processing Study (CHAPS). First, the model reproduces the trends of higher nitrate volume fractions in cloud droplet residuals compared to interstitial nonactivated aerosols, as measured using an aerosol mass spectrometer. Comparing simulations with cloud chemistry turned on and off, we show that nitric acid vapor uptake by cloud droplets explains the higher nitrate content of cloud droplet residuals. Second, the model reasonably represents the observations of the first aerosol indirect effect where pollutants in the vicinity of Oklahoma City increase cloud droplet number concentrations and decrease the droplet effective radius. In addition, as documented using an offline optical code, simulated aerosol optical properties depend on several compensating effects including aerosol water content, size-resolved chemical composition, and refractory index of various particle chemical species. All of our four sensitivity test cases clearly show an increase in simulated absorption and a decrease in single scattering albedo within the Oklahoma City plume relative to conditions outside the plume. While previous studies have often focused on cloud-aerosol interactions in stratiform and deep convective clouds, this study highlights the ability of regional-scale models to represent some of the important aspects of cloud-aerosol interactions associated with fields of short-lived shallow cumuli.

SO EARTH AND PLANETARY SCIENCE LETTERS LA English DT Article DE melt inclusions; subduction; volatiles; mantle melting; magma chamber; eruption ID SUBDUCTION-ZONE MAGMATISM; HOSTED MELT INCLUSIONS; MID-ATLANTIC RIDGE; TRACE-ELEMENTS; H2O CONTENT; COSTA-RICA; FRACTIONAL CRYSTALLIZATION; BASALTIC ANDESITES; CONTINENTAL-CRUST; VOLATILE CONTENTS AB The last 15 yr have seen an explosion of data on the volatile contents of magmas parental to arc volcanoes. This has occurred due to the intense study of melt inclusions trapped in volcanic phenocrysts, aliquots of magma that have presumably escaped degassing during eruption. The surprising first-order result is the narrow range in H2O concentrations in the least degassed melt inclusions from each volcano. Nearly all arc volcanoes are sourced with mafic magmas that contain 2-6 wt% H2O. The average for each arc varies even less, from 3.2 (for the Cascades) to 4.5 (for the Marianas), with a global average of 3.9 +/- 0.4 wt% H2O. Significant variations occur from volcano to volcano within each arc, but the means are indistinguishable within one s.d. The narrow range and common average value for H2O are in stark contrast to the concentrations of most other subduction tracers, such as Nb or Ba, which vary by orders of magnitude. A modulating process, either in the crust or mantle, is likely responsible for the restricted range in the H2O contents of arc melt inclusions. One possibility is that melt inclusion H2O values reflect vapor saturation at the last storage depth in the crust prior to eruption. In this scenario, magmas rise from the mantle with variable H2O contents (> 4 wt%), become vapor-saturated and start degassing, and continue to degas up until the depth at which they stall. If the stalling depths are similar to 6 km, which is common for storage depths beneath volcanoes, magmas would be saturated at similar to 4 wt% H2O, and melt inclusions, most of which become closed during further ascent, would thus record <= 4 wt% H2O. Another possibility is that the mantle melting process modulates water content in the melt such that magmas rise out of the mantle with similar to 4 wt% H2O. A strong relationship between the water content of the source, H2O(o) and the degree of melting (F) maintains nearly constant water contents in the melt for a restricted range in mantle temperature. Magmas with 3-4 wt% H2O can be generated at similar to 50 degrees below the dry solidus for a wide range in F and H2O(o). The narrow range in wedge temperatures may be another manifestation of a planet with average upper mantle of 1400 degrees C potential temperature. The characteristic mean and range of H2O contents of arc magmas has implications for both the volatile fuel for explosive eruptions and the mass balance of H2O recycled through subduction zones.

TI Noble gas radionuclides in Yellowstone geothermal gas emissions: A reconnaissance SO CHEMICAL GEOLOGY LA English DT Article DE Noble gas radionuclides; Yellostone National Park; Fluid Residence Time ID NATIONAL-PARK; HELIUM-ISOTOPES; GEYSER BASIN; KRYPTON; AR-39; GEOCHEMISTRY; TRANSPORT; DYNAMICS; WATERS; FLUIDS AB A reconnaissance investigation of noble gas radionuclides (Ar-38, Kr-81, and Kr-88) in gas emissions from several geothermal features at Yellowstone National Park was performed to explore tracer applications of these nuclides in an active hydrothermal system. Prior studies of the Yellowstone system using stable noble gas isotopes show that the thermal fluids contain a mixture of atmospheric, mantle, and crustal components. Noble gas radio-nuclide measurements provide complementary chronometric information regarding subsurface residence times of thermal fluids, from decay of Kr-81 and Kr-88 as well as in situ production and release of nucleogenic Ar-38 and radiogenic Ar-40* in the reservoir rock. Argon-39 isotopic abundances in air-corrected samples exceed those of atmospheric Ar by 705 to 1217%, indicating substantial Ar contribution to thermal fluids by fluid-rock interaction. Upper limits on deep thermal fluid mean residence times, estimated from Ar-39/Ar-40* ratios, are about 100 kyr for features in the Gibbon and Norris Geyser Basin areas, and is about 30 kyr in Lower Geyser Basin, with the key assumption that the fluid acquires its crustal component of Ar in Quaternary volcanic rock of the Yellowstone caldera. Input of crustal Ar from older aquifer rocks would reduce these apparent mean residence times. Kr-81 isotopic abundances in the gas samples yield upper limits on residence time that are consistent with those obtained from Ar-39/Ar-40 ratios. (C) 2012 Elsevier B.V. All rights reserved.

TI Geologic CO2 input into groundwater and the atmosphere, Soda Springs, ID, USA SO CHEMICAL GEOLOGY LA English DT Article DE Springs; CO2 degassing; Eddy covariance; Mantle; Metamorphic decarbonation; Accumulation chamber ID MEADE THRUST ALLOCHTHON; CARBON-DIOXIDE; MAMMOTH MOUNTAIN; EDDY COVARIANCE; FLUX MEASUREMENTS; DIFFUSE EMISSION; NOBLE-GASES; SOUTHEASTERN IDAHO; REGIONAL AQUIFERS; CALIFORNIA AB A set of CO2 flux, geochemical, and hydrologic measurement techniques was used to characterize the source of and quantify gaseous and dissolved CO2 discharges from the area of Soda Springs, southeastern Idaho. An eddy covariance system was deployed for similar to one month near a bubbling spring and measured net CO2 fluxes from -74 to 1147 g m(-2) d(-1). An inversion of measured eddy covariance CO2 fluxes and corresponding modeled source weight functions mapped the surface CO2 flux distribution within and quantified CO2 emission rate (24.9 t d(-1)) from a 0.05 km(2) area surrounding the spring. Soil CO2 fluxes (<1 to 52,178 g m(-2) d(-1)) were measured within a 0.05 km(2) area of diffuse degassing using the accumulation chamber method. The estimated CO2 emission rate from this area was 49 t d(-1). A carbon mass balance approach was used to estimate dissolved CO2 discharges from contributing sources at nine springs and the Soda Springs geyser. Total dissolved inorganic carbon (as CO2) discharge for all sampled groundwater features was 57.1 t d(-1). Of this quantity, approximately 3% was derived from biogenic carbon dissolved in infiltrating groundwater, 35% was derived from carbonate mineral dissolution within the aquifer(s), and 62% was derived from deep source(s). Isotopic compositions of helium (1.74-2.37 R-a) and deeply derived carbon (delta C-13 approximate to 3 parts per thousand) suggested contribution of volatiles from mantle and carbonate sources. Assuming that the deeply derived CO2 discharge estimated for sampled groundwater features (similar to 35 t d(-1)) is representative of springs throughout the study area, the total rate of deeply derived CO2 input into the groundwater system within this area could be similar to 350 t d(-1), similar to CO2 emission rates from a number of quiescent volcanoes.

Concentrations of He-4, corrected for air-bubble entrainment, vary from 4.15 to 62.7 (x 10(-8)) cm(3) STP g(-1) H2O. He-3/He-4 ratios vary from 0.09 to 3.52 R-A (Where R-A=air He-3/He-4), consistent with up to 44% mantle helium in samples. A subset of 10 samples was analyzed for the major volatile phase (CO2) - the hypothesized carrier phase of the helium in the mantle-crust system: CO2/He-3 ratios vary from 0.614 to 142 (x10(11)), and delta C-13 (CO2) values vary from -21.5 to -11.9 parts per thousand (vs. PDB). He-3/He-4 ratios and CO2 concentrations are highest in the wells located in the Mil Potrero and Cuddy valleys adjacent to the SAFS. The elevated He-3/He-4 ratios are interpreted to be a consequence of a mantle volatile flux though the SAFS diluted by radiogenic He produced in the crust. Samples with the highest He-3/He-4 ratios also had the lowest CO2/He-3 ratios. The combined helium isotope, He-CO2 elemental relationships, and delta C-13 (CO2) values of the groundwater volatiles reveal a mixture of mantle and deep crustal (metamorphic) fluid origins. The flux of fluids into the seismogenic zone at high hydrostatic pressure may cause fault rupture, and transfer volatiles into the shallow crust. We calculate an upward fluid flow rate of 147 mm a(-1) along the SAFS, up to 37 times higher than previous estimates (Kennedy et al., 1997). However, using newly identified characteristics of the SAFS, we calculate a total flux of He-3 along the SAFS of 7.4x10(3) cm(3) STP a(-1) (033 mol He-3 a(-1)), and a CO2 flux of 1.5x10(13) cm(3)STP a(-1) (6.6x10(8) mol a(-1)), similar to 1% of previous estimates. Lower fluxes along the Big Bend section of the SAFS suggest that the flux of mantle volatiles alone is insufficient to cause the super hydrostatic pressure in the seismogenic zone; however, results identify crustal (metamorphic) fluids as a major component of the CO2 volatile budget, which may represent the additional flux necessary for fault weakening pressure in the SAFS.

Data were collected from a sample prepared from the bathophilous tubeworm Lamellibrachia satsuma. The unit cell contains one chain having one N-acetylglucosamine residue in the asymmetric unit with the hydroxymethyl group in gt conformation (a = 4.682 angstrom, b = 14.351 angstrom, c = 10.275 angstrom and gamma = 96.24 degrees in space group P2(1)). The complexed EDA molecule has a trans conformation with one amino group tightly bound to the primary alcohol hydroxyl group 06 atom of the N-acetylglucosamine residue in an arrangement similar to that found in the EDA-cellulose I complex. The other amino group has no detectible hydrogen bonding and higher thermal displacement. This common interaction between EDA and 06 would appear to be the dominant driving interaction for complex formation with both beta-chitin and cellulose. (C) 2012 Elsevier Ltd. All rights reserved.

Instead of the typical powder electrodes with poorly defined surface coatings, thin film electrodes were prepared with well-defined oxide coating thicknesses to investigate the influence of coating on surface reactivity via X-ray photoelectron spectroscopy (XPS). ZnO is found to decompose during the first charge whereas Al2O3 and ZrO2 are stable for more than 100 cycles. ZrO2, however, importantly limits the available Li storage capacity of the electrochemical reaction due to poorer kinetics. Al2O3 offers the best results in term of capacity retention. Upon cycling, the evidence of a signal at 75.4 eV in the Al2p binding energy spectrum indicates the partial fluorination of Al2O3 into, perhaps, Al2O2F2.

An analytical tool, based on an electrochemical analogy to thermal fin analysis, has been developed to support the design of such microstructures. An adapted version of this tool is presented for analyzing the performance of microstructural geometry in dye-sensitized solar cells. This electrochemical fin model is capable of describing experimentally observed performance gains associated with specific microstructural geometries. The assessment of structures based on nanorod and nanoparticle architectures is addressed, and insights into trade-offs between surface charge transfer reactions and diffusive transport in solid photoelectrode phases are discussed.

We find that the measured distributions of such electromagnetic emissions, while having some features not well understood if hypothesized to entirely arise from a thermalized Quark-Gluon Plasma, have some qualitative features that might be described after including effects from a thermalizing Glasma. The shape and centrality dependence of the transverse momentum spectra of the so-called "thermal photons" are well described. The mass and transverse momentum dependence of intermediate mass dileptons also agree with our estimates. The low transverse momenta from which the excessive dileptons (in low to intermediate mass region) arise is suggestive of emissions from a Bose condensate. We also predict the centrality dependence of dilepton production. Uncertainties in the current approach and improvements in the future are discussed. (C) 2013 Elsevier B.V. All rights reserved.

TI Influence of the alkoxide group, solvent, catalyst, and concentration on the gelation and porosity of hexylene-bridged polysilsesquioxanes SO JOURNAL OF NON-CRYSTALLINE SOLIDS LA English DT Article DE Polysilsesquioxanes; Hexylene-bridged; Porosity; Sol-gel; Gelation ID SOL-GEL MATERIALS; ORGANIC-INORGANIC MATERIALS; HYBRID; CHEMISTRY AB 1,6-Hexylene-bridged polysilsesquioxanes are hybrid organic-inorganic materials prepared by sol-gel polymerization of 1,6-bis(trialkoxysilyl)hexanes. Due to the trialkoxysilyl groups bonded to each end of the hexylene bridging group, hydrolysis and condensation easily gave network polymers in the form of gels. When the solvent evaporates from the gels, dry gels or xerogels are obtained that may be non-porous or porous depending on whether the network is compliant enough to resist collapse or not. Hexylene-bridged materials appear to lie on the boundary between polysilsesquioxanes with bridging groups that are sufficiently long and flexible to allow porosity to collapse with drying and those with bridging groups that are short and stiff enough to prevent collapse of porosity during drying. Under base-catalyzed conditions, 1,6-bis(triethoxysilyl)hexane polymerizes to yield porous xerogels while under acidic conditions, non-porous xerogels are obtained. In this study, we examine the effects of the alkoxide group on the sol-gel process and the resulting xerogels porosity and provide a more detailed examination of the relative importance of the sol-gel reaction parameters (concentration, pH, solvent). I, 6-Bis(trimethoxysilyl)hexane (1), 1,6-bis(triethoxysilyl)hexane (2), and 1, 6-bis(tri-n-propoxysilyl)hexane (3) were polymerized under acidic and basic conditions in methanol, ethanol, or n-propanol, respectively, as well as tetrahydrofuran (THE). The resulting gels were dried to provide xerogels that were characterized by SEM, solid state C-13 and Si-29 Cross Polarization Magic Angle Spinning (CP MAS) NMR spectroscopy, and nitrogen and carbon dioxide sorption porosimetry.

Thermoelectricity has usually been considered in the context of stable material phases. Here we report that the fluctuation of structures during the second-order phase transition in Cu2Se semiconductor breaks the conventional trends of thermoelectric transports in normal phases, leading to a critically phase-transition-enhanced thermoelectric figure of merit zT above unity at 400 K, a three times larger value than for the normal phases. Dynamic structural transformations introduce intensive fluctuations and extreme complexity, which enhance carrier entropy and thus the thermopower, and strongly scatter carriers and phonons as well to make their transports behave critically.

The SnO2 morphology can be tuned by using AlOOH sol and gamma-Al2O3 as additive. The hollow SnO2 microspheres with incomplete core-shell structure prepared with small amount of gamma-Al2O3 presented the best cycling performance in Li-ion battery, exhibiting a specific capacity of 374.2 mAh g(-1) up to 100 cycles. The superior performance can be mainly attributed to the formation of more and smaller SnO2 hollow microspheres and partial core-shell SnO2 microspheres resulting from the gamma-Al2O3 condensation nucleus. The unique hollow and core-shell composite structure of SnO2 is capable of reducing the volume changes during Li insertion-extraction. (C) 2012 Published by Elsevier B.V.

We have demonstrated that this visual capability has made some challenging genome analysis problems relatively easy to solve. We have applied this capability to a number of challenging problems, including (a) identification of horizontally transferred genes, (b) identification of genomic islands with special properties and (c) binning of metagenomic sequences, and achieved highly encouraging results. These application results inspired us to develop this barcode-based genome analysis server for public service, which supports the following capabilities: (a) calculation of the k-mer based barcode image for a provided DNA sequence; (b) detection of sequence fragments in a given genome with distinct barcodes from those of the majority of the genome, (c) clustering of provided DNA sequences into groups having similar barcodes; and (d) homology-based search using Blast against a genome database for any selected genomic regions deemed to have interesting barcodes. The barcode server provides a job management capability, allowing processing of a large number of analysis jobs for barcode-based comparative genome analyses.

Hu, Qing TI Effective mode selector for tunable terahertz wire lasers SO OPTICS LETTERS LA English DT Article AB We demonstrate an effective mode selector design that enables a terahertz quantum cascade wire laser to have a robust single-mode operation at frequencies much lower than the gain peak. This is achieved by selectively guiding the undesired modes into a lossy session while keeping the desired lasing mode largely unperturbed. The large mode discrimination obtained by this mode selector is necessary to further extend the tuning range to the lower half of the gain curve. Additionally, the connectors of this mode selector conveniently provide electrical bias to the wire lasers without degrading the lasing performance.

The model distinguishes and quantifies the contributions from population and thermal effects. Laser-induced lensing in ytterbium-doped fluorozirconate glass ZBLAN:Yb3+ is measured, and the thermal and optical properties obtained from analyzing the data with the proposed model agree well with published values. Photothermal techniques are used extensively for the investigation of laser and laser-cooling materials, and the model developed here enables the interpretation of convoluted laser-induced lensing signals that have contributions from different sources.

TI Infrared microcalorimetric spectroscopy using quantum cascade lasers SO OPTICS LETTERS LA English DT Article ID PHOTOTHERMAL SPECTROSCOPY; MICROCANTILEVERS; CANTILEVER; SENSORS AB We have investigated an IR microcalorimetric spectroscopy technique that can be used to detect the presence of trace amounts of target molecules. The chemical detection is accomplished by obtaining the IR photothermal spectra of molecules adsorbed on the surface of uncooled thermal micromechanical detectors. Although we use a chemical layer to absorb target molecules, IR microcalorimetric spectroscopy requires no chemical specific coatings. The chemical specificity of the presented method is a consequence of the wavelength-specific absorption of IR photons from tunable quantum cascade lasers due to vibrational spectral bands of the analyte. We have obtained IR photothermal spectra for trace concentrations of 1,3,5-Trinitroperhydro-1,3,5-triazine and a monolayer of 2-Sulfanylethan-1-ol (2-mercaptoethanol) over the wavelength region from 6 to 10 mu m. We found that both chemicals exhibit a number of photothermal absorption features that are in good agreement with their respective IR spectra.

Here, we report on the novel use of both neutron and high resolution x-ray diffraction to help elucidate the identity of the catalytic base in the acylation part of the catalytic cycle, wherein the beta-lactam ring is opened and an acyl-enzyme intermediate forms. To generate protein crystals optimized for neutron diffraction, we produced a perdeuterated form of the Toho-1 beta-lactamase R274N/R276N mutant. Protein perdeuteration, which involves replacing all of the hydrogen atoms in a protein with deuterium, gives a much stronger signal in neutron diffraction and enables the positions of individual deuterium atoms to be located. We also synthesized a perdeuterated acylation transition state analog, benzothiophene-2-boronic acid, which was also isotopically enriched with B-11, as B-10 is a known neutron absorber. Using the neutron diffraction data from the perdeuterated enzyme-inhibitor complex, we were able to determine the positions of deuterium atoms in the active site directly rather than by inference. The neutron diffraction results, along with supporting bond-length analysis from high resolution x-ray diffraction, strongly suggest that Glu-166 acts as the general base during the acylation reaction.

To effectively quantify the severity and extent of these events, tools that allow for rapid assessment at the landscape scale are required. Past studies using high spatial resolution satellite imagery have primarily focused on detecting green, red, and gray tree canopies during and shortly after tree damage or mortality has occurred. However, detecting trees in various stages of death is not always possible due to limited availability of archived satellite imagery. Here we assess the capability of high spatial resolution satellite imagery for tree mortality detection in a southwestern U.S. mixed species woodland using archived satellite images acquired prior to mortality and well after dead trees had dropped their leaves. We developed a multistep classification approach that uses: supervised masking of non-tree image elements: bi-temporal ( pre- and post-mortality) differencing of normalized difference vegetation index (NDVI) and red:green ratio (RGI): and unsupervised multivariate clustering of pixels into live and dead tree classes using a Gaussian mixture model. Classification accuracies were improved in a final step by tuning the rules of pixel classification using the posterior probabilities of class membership obtained from the Gaussian mixture model. Classifications were produced for two images acquired post-mortality with overall accuracies of 97.9% and 98.5%, respectively. Classified images were combined with land cover data to characterize the spatiotemporal characteristics of tree mortality across areas with differences in tree species composition. We found that 38% of tree crown area was lost during the drought period between 2002 and 2006. The majority of tree mortality during this period was concentrated in pinon-juniper (Pinus edulis-Juniperus monosperma) woodlands. An additional 20% of the tree canopy died or was removed between 2006 and 2011, primarily in areas experiencing wildfire and management activity. -Our results demonstrate that unsupervised clustering of bi-temporal NDVI and RGI differences can be used to detect tree mortality resulting from numerous causes and in several forest cover types.

Egan, Rob Frazier, Peter I. Wang, Zhong TI ALE: a generic assembly likelihood evaluation framework for assessing the accuracy of genome and metagenome assemblies SO BIOINFORMATICS LA English DT Article ID SEQUENCE; INSIGHTS AB Motivation: Researchers need general purpose methods for objectively evaluating the accuracy of single and metagenome assemblies and for automatically detecting any errors they may contain. Current methods do not fully meet this need because they require a reference, only consider one of the many aspects of assembly quality or lack statistical justification, and none are designed to evaluate metagenome assemblies. Results: In this article, we present an Assembly Likelihood Evaluation (ALE) framework that overcomes these limitations, systematically evaluating the accuracy of an assembly in a reference-independent manner using rigorous statistical methods. This framework is comprehensive, and integrates read quality, mate pair orientation and insert length (for paired-end reads), sequencing coverage, read alignment and k-mer frequency. ALE pinpoints synthetic errors in both single and metagenomic assemblies, including single-base errors, insertions/deletions, genome rearrangements and chimeric assemblies presented in metagenomes. At the genome level with real-world data, ALE identifies three large misassemblies from the Spirochaeta smaragdinae finished genome, which were all independently validated by Pacific Biosciences sequencing. At the single-base level with Illumina data, ALE recovers 215 of 222 (97%) single nucleotide variants in a training set from a GC-rich Rhodobacter sphaeroides genome. Using real Pacific Biosciences data, ALE identifies 12 of 12 synthetic errors in a Lambda Phage genome, surpassing even Pacific Biosciences' own variant caller, EviCons. In summary, the ALE framework provides a comprehensive, reference-independent and statistically rigorous measure of single genome and metagenome assembly accuracy, which can be used to identify misassemblies or to optimize the assembly process.

A reverse vertical Bridgman technique was used to grow the salt ingots. The investigated parameters were: (1) the advancement rate, (2) the crucible lid configuration, (3) the amount of salt mixture, (4) the initial composition of CsCl, and (5) the temperature difference between the high and low furnace zones. From each grown salt ingot, samples were taken axially and analyzed using inductively coupled plasma mass spectrometry. Results show that CsCl concentrations at the top of the ingots were low and increased to a maximum at the bottom of the salt. Salt (LiCl-KCl) recycle percentages for the experiments ranged from 50% to 75% and the CsCl composition in the waste salt was low. To increase the recycle percentage and the concentration of CsCl in the waste form, multiple crystallization stages were explored showing that they were practical under the optimal experimental conditions at 5.0 mm/h rate with a lid configuration and temperature difference of 200 degrees C for a total of five crystallization stages. Up to 88% of the LiCl-KCl salt can be recycled under these proposed conditions. (c) 2012 Elsevier Ltd. All rights reserved.

TI Low cycle fatigue and creep-fatigue behavior of Ni-based alloy 230 at 850 degrees C SO MATERIALS SCIENCE AND ENGINEERING A-STRUCTURAL MATERIALS PROPERTIES MICROSTRUCTURE AND PROCESSING LA English DT Article DE Creep-fatigue; Nickel based superalloys; EBSD; High-temperature deformation; Precipitation; Failure ID BOUNDARY-CHARACTER-DISTRIBUTION; CRACK-GROWTH BEHAVIOR; GRAIN-BOUNDARIES; HOLD-TIME; TEMPERATURE; SUPERALLOY; DISLOCATION; INCONEL-617 AB Strain-controlled low cycle fatigue (LCF) and creep-fatigue testing of Ni-based alloy 230 were carried out at 850 degrees C. The material creep-fatigue life decreased compared with its low cycle fatigue life at the same total strain range. Longer hold time at peak tensile strain further reduced the material creep-fatigue life. Based on the electron backscatter diffraction, a novel material deformation characterization method was applied, which revealed that in low cycle fatigue testing as the total strain range increased, the deformation was segregated to grain boundaries since the test temperature was higher than the material equicohesive temperature and grain boundaries became weaker regions compared with grains. Creep-fatigue tests enhanced the localized deformation, resulting in material interior intergranular cracking, and accelerated material damage. Precipitation in alloy 230 helped slip dispersion, favorable for fatigue property, but grain boundary cellular precipitates formed after material exposure to the elevated temperature had a deleterious effect on the material low cycle fatigue and creep-fatigue property.

TI Chiral magnetism and helimagnons in a pyrochlore antiferromagnet SO PHYSICAL REVIEW B LA English DT Article ID FRUSTRATED ANTIFERROMAGNETS; SPIN; YMN2 AB Recent neutron scattering measurements on the spinel CdCr2O4 revealed a rare example of helical magnetic order in geometrically frustrated pyrochlore antiferromagnet. The spin spiral characterized by an incommensurate wave vector Q = 2 pi( 0, delta, 1) with delta approximate to 0.09 is accompanied by a tetragonal distortion. Here we conduct a systematic study on the magnetic ground state resulting from the interplay between the Dzyaloshinskii-Moriya interaction and further neighbor exchange couplings, two of the most important mechanisms for stabilizing incommensurate spin orders. We compute the low-energy spin-wave spectrum based on a microscopic spin Hamiltonian and find a dispersion relation characteristic of the helimagnons. By numerically integrating the Landau-Lifshitz-Gilbert equation with realistic model parameters, an overall agreement between experiment and the numerical spectrum, lending further support to the view that a softened optical phonon triggers the magnetic transition and endows the lattice a chirality.

TI Magnetic-field-tuned quantum criticality of the heavy-fermion system YbPtBi SO PHYSICAL REVIEW B LA English DT Article ID STRONGLY CORRELATED METALS; CRITICAL-POINT; TRANSPORT-PROPERTIES; PHASE-TRANSITIONS; COMPOUND YBBIPT; ANTIFERROMAGNETISM; TEMPERATURE; RESISTIVITY; CHROMIUM; SURFACE AB In this paper, we present systematic measurements of the temperature and magnetic field dependencies of the thermodynamic and transport properties of the Yb-based heavy fermion YbPtBi for temperatures down to 0.02 K with magnetic fields up to 140 kOe to address the possible existence of a field-tuned quantum critical point. Measurements of magnetic-field- and temperature-dependent resistivity, specific heat, thermal expansion, Hall effect, and thermoelectric power indicate that the AFM order can be suppressed by an applied magnetic field of H-c similar to 4 kOe. In the H-T phase diagram of YbPtBi, three regimes of its low-temperature states emerge: (I) AFMstate, characterized by a spin density wave-like feature, which can be suppressed to T = 0 by the relatively small magnetic field of H-c similar to 4 kOe; (II) field-induced anomalous state in which the electrical resistivity follows Delta(rho)(T) proportional to T-1.5 between H-c and similar to 8 kOe; and (III) Fermi liquid (FL) state in which Delta(rho)(T) proportional to T-2 for H >= 8 kOe. Regions I and II are separated at T = 0 by what appears to be a quantum critical point. Whereas region III appears to be a FL associated with the hybridized 4f states of Yb, region II may be a manifestation of a spin liquid state. DOI: 10.1103/PhysRevB.87.075120 C1 [Mun, E.

TI Interplay of topological surface and bulk electronic states in Bi2Se3 SO PHYSICAL REVIEW B LA English DT Article ID AUGMENTED-WAVE METHOD; SINGLE DIRAC CONE; INSULATORS; BI2TE3 AB In this paper we present scanning tunneling microscopy density-of-states measurements and electronic structure calculations of the topological insulator Bi2Se3. The measurements show significant background states in addition to the expected Dirac cone. Density-functional calculations using a slab model and analysis of the partial density of states show that the background is consistent with bulklike states with small amplitudes at the surface. The topological surface states coexist with bulklike states in the valence band, appearing as a shoulder in the projected band structure. These results strongly support the picture suggested by recent scattering experiments of the quantum interference of topological and bulklike surface states.

TI Epitaxy-distorted spin-orbit Mott insulator in Sr2IrO4 thin films SO PHYSICAL REVIEW B LA English DT Article ID TRANSITION; METAL AB High-quality epitaxial thin films of J(eff) = 1/2 Mott insulator Sr2IrO4 with increasing in-plane tensile strain have been grown on top of SrTiO3(001) substrates. Increasing the in-plane tensile strain up to similar to 0.3% was observed to drop the c/a tetragonality by 1.2%. X-ray absorption spectroscopy detected a strong reduction of the linear dichroism upon increasing in-plane tensile strain towards a reduced anisotropy in the local electronic structure. While the most relaxed thin film shows a consistent dependence with previously reported single crystal bulk measurements, electrical transport reveals a charge gap reduction from 200 meV down to 50 meV for the thinnest and most epitaxy-distorted film. We argue that the reduced tetragonality plays a major role in the change of the electronic structure, which is reflected in the change of the transport properties. Our work opens the possibility for exploiting epitaxial strain as a tool for both structural and functional manipulation of spin-orbit Mott systems. DOI: 10.1103/PhysRevB.87.085121 C1 [Serrao, C.

In the two-impurity Anderson model, we show that the excitation of this composite fermion has a finite spectral weight near the Fermi energy in the regime dominated by intersite spin exchange coupling where the Kondo fixed point is prevented. From scattering off this coherent composite fermion mode, the excitation of the regular fermion f(i sigma) develops a pseudogap and its self-energy is singular. Conversely, when the regular fermion develops Kondo resonance in the Kondo resonance regime, the excitation of the composite fermion develops a pseudogap instead. We argue that the composite fermion could develop a Fermi surface but "hidden" from charge excitations in lattice generalizations.

This is explicitly demonstrated in a simple wounded nucleon model, and the general case is also discussed. It is argued that rapidity fluctuations are large compared to normal statistical fluctuations. We show how to extract different components of the fluctuating fireball shape from the measured two-particle rapidity correlation function. The experimental possibility of studying the longitudinal initial conditions in heavy-ion and proton-proton collisions is emphasized.

TI Spin response and neutrino emissivity of dense neutron matter SO PHYSICAL REVIEW C LA English DT Article ID SUPERNOVA CORES; NUCLEON; BREMSSTRAHLUNG; STARS; SCATTERING; FLUCTUATIONS AB We study the spin response of cold dense neutron matter in the limit of zero momentum transfer and show that the frequency dependence of the long-wavelength spin response is well constrained by sum rules and the asymptotic behavior of the two-particle response at high frequency. The sum rules are calculated using an auxiliary field diffusion Monte Carlo technique and the high-frequency two-particle response is calculated for several nucleon-nucleon potentials. At nuclear saturation density, the sum rules suggest that the strength of the spin response peaks at omega similar or equal to 40-60 MeV, decays rapidly for omega >= 100 MeV, and has a sizable strength below 40 MeV. This strength at relatively low energy may lead to enhanced neutrino production rates in dense neutron-rich matter at temperatures of relevance to core-collapse supernova.

The proton-gamma coincidences of Ni-53 beta-delayed proton emission were observed. Based on the analysis of the proton-gamma coincidence events, it was inferred that the previous assignment of the excitation energy for the isobaric analog state in Co-53 may be problematic. The half-lives of these nuclei were obtained, in which the uncertainty of Co-52 half-life was reduced by a factor of 3. The half-lives were evaluated and used as inputs of nucleosynthesis calculations of the rapid proton-capture process in an x-ray burst. DOI: 10.1103/PhysRevC.87.024312 C1 [Su, J.; Liu, W. P.; Shu, N.

CA BaBar Collaboration TI Search for di-muon decays of a low-mass Higgs boson in radiative decays of the Gamma(1S) SO PHYSICAL REVIEW D LA English DT Article ID LEPTONIC DECAYS; QUARKONIUM AB We search for di-muon decays of a low-mass Higgs boson (A(0)) produced in radiative Gamma(1S) decays. The Gamma(1S) sample is selected by tagging the pion pair in the Gamma(2S, 3S) -> pi(+)pi(-) Gamma(1S) transitions, using a data sample of 92.8 x 10(6) Gamma(2S) and 116.8 x 10(6) Gamma(3S) events collected by the BABAR detector. We find no evidence for A(0) production and set 90% confidence level upper limits on the product branching fraction B(Gamma(1S) -> gamma Lambda(0)) x B(Lambda(0)->mu(+)mu(-)) in the range of (0.28 - 9.7) x 10(-6) for 0.212 <= m(A0) <= 9.20 GeV/c(2). The results are combined with our previous measurements of Gamma(2S,3S) -> gamma Lambda(0), Lambda(0) -> mu(+)mu(-) to set limits on the effective coupling of the b quark to the Lambda(0).

Such a measurement is challenging due to the finite detector resolution, the absolute energy scale calibration, and the degeneracies caused by current experimental uncertainty of vertical bar Delta m(32)(2)vertical bar. The standard chi(2) method is compared with a proposed Fourier transformation method. In addition, we show that for such a measurement to succeed, one must understand the nonlinearity of the detector energy scale at the level of a few tenths of percent.

Simulations of the EBIS charge breeder performance and the related ion transport systems are reported. Propagation of the electron beam through the EBIS was verified, and the anticipated incident power density within the electron collector was identified. The full normalized acceptance of the charge breeder with a 2 A electron beam, 0: 024 pi mm mrad for nominal operating parameters, was determined by simulating ion injection into the EBIS. The optics of the ion transport lines were carefully optimized to achieve well-matched ion injection, to minimize emittance growth of the injected and extracted ion beams, and to enable adequate testing of the charge bred ions prior to installation in ATLAS.

For the first time, the method makes the accurate prediction of the local charge distribution, force and torque on finite-sized particles possible. In the present work, the method is extended to heterogeneous mixtures of elliptical particles to further investigate the effects of the orientation and anisotropy. The direct resolution of the effect of fields in heterogeneous mixtures of elliptical particles to determine local and global properties and responses has many applications in engineering, mechanics, physics, chemistry, and biology. The method can be applied to heterogeneous materials, heterogeneous functional materials, microfluidics, and devices such as electric double layer capacitors. In the present paper, the accuracy of the method is extensively investigated even for very challenging problems, for example, for elongated rod-like particles with very high aspect ratios. The accuracy and efficiency of the method suggests that it can be used for many important applications of broad interest. (c) 2012 Elsevier Inc. All rights reserved.

To simulate such problems in an Eulerian framework on a fixed Cartesian mesh, interfaces (free surfaces as well as interacting material interfaces) are tracked as levelsets; to resolve shocks and interfaces, a quad-tree adaptive mesh is employed. This paper addresses issues associated with the treatment of all interfaces as sharp entities by defining ghost fields on each side of the interface. Collisions between embedded objects are resolved using an efficient collision detection algorithm and appropriate interfacial conditions are supplied. Key issues of supplying interfacial conditions at the precise location of the sharp interface and populating the ghost cells with physically consistent values during and beyond fragmentation events are addressed. Numerous examples pertaining to impact, penetration, void collapse and fragmentation phenomena are presented along with careful benchmarking to establish the validity, accuracy and versatility of the approach.

TI A space-time smooth artificial viscosity method for nonlinear conservation laws SO JOURNAL OF COMPUTATIONAL PHYSICS LA English DT Article DE Artificial viscosity; Numerical shock-capturing; Conservation laws; Euler equations; Contact discontinuities ID ESSENTIALLY NONOSCILLATORY SCHEMES; COMPUTATIONAL FLUID-DYNAMICS; FINITE-ELEMENT FORMULATION; SHOCK-CAPTURING SCHEMES; EFFICIENT IMPLEMENTATION; EULER EQUATIONS; HYPERBOLIC SYSTEMS; COMPRESSIBLE EULER; GAS-DYNAMICS; APPROXIMATIONS AB We introduce a new methodology for adding localized, space-time smooth, artificial viscosity to nonlinear systems of conservation laws which propagate shock waves, rarefactions, and contact discontinuities, which we call the C-method. We shall focus our attention on the compressible Euler equations in one space dimension. The novel feature of our approach involves the coupling of a linear scalar reaction-diffusion equation to our system of conservation laws, whose solution C(x, t) is the coefficient to an additional (and artificial) term added to the flux, which determines the location, localization, and strength of the artificial viscosity. Near shock discontinuities, C(x, t) is large and localized, and transitions smoothly in space-time to zero away from discontinuities. Our approach is a provably convergent, spacetime-regularized variant of the original idea of Richtmeyer and Von Neumann, and is provided at the level of the PDE, thus allowing a host of numerical discretization schemes to be employed. We demonstrate the effectiveness of the C-method with three different numerical implementations and apply these to a collection of classical problems: the Sod shock-tube, the Osher-Shu shock-tube, the Woodward-Colella blast wave and the Leblanc shock-tube. First, we use a classical continuous finite-element implementation using second-order discretization in both space and time, FEM-C. Second, we use a simplified WENO scheme within our C-method framework, WENO-C. Third, we use WENO with the Lax-Friedrichs flux together with the C-equation, and call this WENO-LF-C. All three schemes yield higher-order discretization strategies, which provide sharp shock resolution with minimal overshoot and noise, and compare well with higher-order WENO schemes that employ approximate Riemann solvers, outperforming them for the difficult Leblanc shock tube experiment.

We have evaluated the effect of functionalization by measuring the sorption of CO2, CH4, and N-2 at 35 degrees C for pressures up to 10 bar. Zwitterion functionalized nanotubes were found to be highly hygroscopic. Thermal gravimetric analysis indicates that water can be desorbed at about 200 degrees C. The adsorption of gases in zwitterion functionalized nanotubes is dramatically reduced when compared with nanotubes functionalized with carboxylic acid groups. The presence of water on the zwitterion functionalized nanotube reduces the sorption even further. Molecular simulations show that three or more zwitterion groups per tube entrance are required to significantly reduce the flux of CO2 into the tubes. Simulations also show that gas phase water is rapidly sorbed into the zwitterion functionalized nanotubes, both increasing the free energy barrier to CO2 entering the tube and also lowering the equilibrium adsorption through competitive adsorption.

TI Daily treadmill exercise attenuates cocaine cue-induced reinstatement and cocaine induced locomotor response but increases cocaine-primed reinstatement SO BEHAVIOURAL BRAIN RESEARCH LA English DT Article DE Dopamine; Exercise; Cocaine; Self-administration; Relapse; Abstinence ID CONDITIONED PLACE PREFERENCE; SEEKING BEHAVIOR; BRAIN NOREPINEPHRINE; RECEPTOR-BINDING; FEMALE RATS; ADULT-RAT; DOPAMINE; DRUG; STRESS; 1-METHYL-4-PHENYL-1,2,3,6-TETRAHYDROPYRIDINE AB Exercise affects neuroplasticity and neurotransmission including dopamine (DA), which modulates drug-taking behavior. Previous research in rodents has shown that exercise may attenuate the rewarding effects of drugs of abuse. The present study examined the effects of high and low exercise on cocaine responses in male Wistar rats that had been trained to self-administer and were compared to a group of sedentary rats. High exercise rats (HE) ran daily on a treadmill for 2 h and low exercise (LE) ran daily for 1 h. After 6 weeks of this exercise regimen, rats were tested over 2 days for reinstatement (day 1: cueinduced reinstatement: day 2: cocaine-primed reinstatement). During cue-induced reinstatement, the sedentary rats showed the expected increase in active lever responses when compared to maintenance, whereas these increased responses were inhibited in the exercised rats (HE and LE). During cocaine-primed reinstatement, however, there was a significant increase in active lever presses when compared to maintenance only in the HE group. This data suggests that chronic exercise during abstinence attenuates the cue-induced reinstatement seen in the sedentary rats by 26% (LE) and 21% (HE). In contrast, only the high exercise rats exhibited sensitized cocaine-seeking behavior (active lever presses) following cocaine-primed reinstatement. Finally, while sedentary rats increased locomotor activity during cocaine-primed reinstatement over that seen with cocaine during maintenance, this was not observed in the exercised rats, suggesting that exercise may interfere with the sensitized locomotor response during cocaine reinstatement.

TI Preparation of mesoporous oxides and their support effects on Pt nanoparticle catalysts in catalytic hydrogenation of furfural SO JOURNAL OF COLLOID AND INTERFACE SCIENCE LA English DT Article DE Pt; Nanoparticle; Mesoporous; Furfural; Hydrogenation; Selectivity ID SUM-FREQUENCY GENERATION; PLATINUM NANOPARTICLES; METAL-OXIDES; VIBRATIONAL SPECTROSCOPY; STRUCTURE SENSITIVITY; SELECTIVITY; SHAPE; SIZE; SILICA; SURFACES AB Mesoporous SiO2, Al2O3, TiO2, Nb2O5, and Ta2O5 were synthesized through a soft-templating approach by a self-assembled framework of Pluronic P123 and utilized for the preparation of 3-dimensional catalysts as supports. Colloidal Pt nanoparticles with an average diameter of 1.9 nm were incorporated into the mesoporous oxides by sonication-induced capillary inclusion. The Pt nanoparticles supported on mesoporous oxides were evaluated in the hydrogenation reaction of furfural (70 tort furfural and 700 torr H-2 with a balance of He) to study the effect of catalyst supports on selectivity. In the temperature ranges of 170-240 degrees C, the major products of this reaction were furan, furfuryl alcohol, and 2-methyl furan through a main reaction pathway of either decarbonylation or carbonyl group hydrogenation. While Pt nanoparticles with the size ranges of 1.5-7.1 exhibited strong structure-dependent selectivity, various supports loaded with only 1.9 nm Pt nanoparticles produced dominantly furan as a major product. Compared to the inert silica support, TiO2 and Nb2O5 facilitated an increase in the production of furfuryl alcohol via carbonyl group hydrogenation as a result of a charge transfer interaction between the Pt and the acidic surface of the oxides. The same trend was confirmed on 2-dimensional type catalysts, in which thin films of SiO2, Al2O3, TiO2, Nb2O5, and ZrO2 were prepared as supports. When furfural hydrogenation was conducted (1 torr furfural, 100 torr H-2, and 659 torr He) over Pt nanoparticle monolayers deposited on oxide substrates, only TiO2 was shown to increase the production of furfuryl alcohol, while other oxides produced furan.

TI Comparing the results of lattice and off-lattice simulations for the melt of nonconcatenated rings SO JOURNAL OF PHYSICS A-MATHEMATICAL AND THEORETICAL LA English DT Article ID COMPUTER-SIMULATION; POLYMERS; GENOME; DYNAMICS; ORGANIZATION; PRINCIPLES; MODEL AB To study the conformational properties of unknotted and nonconcatenated ring polymers in the melt, we present a detailed qualitative and quantitative comparison of simulation data obtained by molecular dynamics simulation using an off-lattice bead-spring model and by Monte Carlo simulation using a lattice model. We observe excellent, and sometimes even unexpectedly good, agreement between the off-lattice and lattice results for many quantities measured including the gyration radii of the ring polymers, gyration radii of their subchains, contact probabilities, surface characteristics, number of contacts between subchains, and the static structure factors of the rings and their subchains. These results are, in part, put in contrast to Moore curves, and the open, linear polymer counterparts. While our analysis is extensive, our understanding of the ring melt conformations is still rather preliminary. C1 [Halverson, Jonathan D.] Brookhaven Natl Lab, Ctr Funct Nanomat, Upton, NY 11973 USA.

Because the lattice Boltzmann equation (LBE) model is based on microscopic models and mesoscopic kinetic equations, it offers many advantages for the study of multi-component or multi-phase flow problems. While the original formulation of Shan and Chen's (SC) model can incorporate some MCMP flow scenarios, the density ratio of the different components is greatly restricted to less than approximately 2.0. This obviously limits the applications of this MCMP LBE model. Hence, based on the original SC MCMP model and the improvements in the single-component multi-phase (SCMP) flow model reported by Yuan and Schaefer, we have developed a new model that can simulate a MCMP system with a high density ratio.

TI The surface structure of alpha-uranophane and its interaction with Eu(III) - An integrated computational and fluorescence spectroscopy study SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID EFFECTIVE CORE POTENTIALS; MOLECULAR-DYNAMICS SIMULATIONS; SPENT NUCLEAR-FUEL; LANTHANIDE(III) COMPLEXES; DICARBOXYLIC-ACIDS; PHASE-FORMATION; DENSITY; UO2; ION; LUMINESCENCE AB Uranophane is a rare U(VI) secondary silicate mineral that is relevant to the long-term performance of high level nuclear waste repositories. It can be formed under oxidizing conditions, potentially acting as an additional barrier to radionuclide migration through the accessible environment via mineral sorption reactions. To help understand the mechanisms involved in such sorption, a combination of theoretical calculations (classical molecular dynamics and ab initio density functional theory), and experimental work (sorption and laser induced fluorescence spectroscopy studies), have been employed to investigate the uranophane vertical bar water interface as well as the interfacial reactivity of the U(VI) silicate toward acidic conditions and radionuclide ion sorption. The combination of theoretical and experimental sorption studies help identify the molecular structure of the surface-sorbed species. Interfacial water is found to orient primarily with the hydrogen-atoms directed towards the negatively charged surface, with sorption sites belonging to three different groups: (1) those involving uranyl oxygen, (2) involving uranyl and silica hydroxyl oxygen atoms, and (3) involving hydroxyl hydrogen. Under basic conditions, deprotonation of the Si-OH groups is predicted to be responsible for uranophane dissolution, while protonation of bridging oxygens is likely responsible for acidic dissolution. Stable inner-sphere sorbed Eu(III) species are observed both experimentally and computationally. Moreover, Eu(III) is found to react with both protonated and deprotonated surface sites, indicating that radionuclides may sorb to the surface of uranophane under a broad range of pH conditions that alter the relative concentrations of protonated and deprotonated surface sites. This is in stark contrast to prior observations regarding other silicate minerals such as quartz, where sorption under basic conditions is enhanced. (C) 2012 Elsevier Ltd. All rights reserved.

TI Molybdenum reduction in a sulfidic lake: Evidence from X-ray absorption fine-structure spectroscopy and implications for the Mo paleoproxy SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID TRACE-METALS; BLACK-SEA; AZOTOBACTER-VINELANDII; EUXINIC SEDIMENTS; PROTEROZOIC OCEAN; CRYSTAL-STRUCTURE; MARINE-SEDIMENTS; ISOTOPE EVIDENCE; ORGANIC-MATTER; GEOCHEMISTRY AB Marine euxinic sediments, particularly organic-rich black shales, are important sinks for oceanic molybdenum (Mo), and the determination of Mo concentration and isotopic composition are used to constrain oxygenation state and specifically expansion of marine anoxic and sulfidic (euxinic) waters in ancient oceans. The use of Mo as a paleo-redox tracer is based on its distinct geochemical behavior in oxic and sulfidic environments. Mo removal from sulfidic waters starts with MoO42- reacting with aqueous H2S to form particle reactive thiomolybdates, MoO4-xSx2-, but the post-thiomolybdate steps and the ultimate Mo host in euxinic sediments are not well understood. We used X-ray absorption fine structure (XAFS) spectroscopy to determine the oxidation state and the molecular coordination environment of pristine, solid phase Mo in sediments from permanently euxinic Lake Cadagno, Switzerland. Samples were taken from a 9-meter piston core representing the last ten thousand years of deposition. The euxinic lake sediments provide unequivocal evidence that the post-thiomolybdate steps along the burial pathway involve Mo(VI) reduction to Mo(IV) before it is ultimately hosted in the sediments. Anoxic samples contain Mo(IV)-S compounds that, when oxidized upon air-exposure, are transformed into Mo(VI)-O, thus confirming our results. This observation is important to better understand the Mo burial pathway from oxic waters to euxinic sediments. Our results support a model where post-thiomolybdate Mo VI reduction proceeds via reactions with zero-valent sulfur, S(0) (mainly S-8, Vorlicek et al., 2004). In this model, Mo is scavenged from sulfidic waters as reactive Mo-polysulfide species, Mo(IV)O(S-4)S2- or Mo(IV)S(S-4)S2-,and not as thiomolybdate (MoOS32 or MoS42) as has been previously assumed. This result can have important implications for how paleoenvironmental redox conditions are inferred from sedimentary Mo enrichments, Mo/TOC ratios, and delta Mo-98, if the Mo accumulation rate is accelerated via the S-8-assisted pathway in settings where partial oxidation of S is possible. For example, euxinic Mo/TOC ratios are predicted not only as a function of Mo concentration in overlying seawater. Instead, the ratio will be higher in sediments deposited under highly sulfidic waters where S-8 is also abundant, such as in settings where the chemocline depth fluctuates considerably and/or oxygen intrusions occur to the overlying bottom waters. Partial oxidation of dissolved sulfide is an important step in polysulfide production. Finally, we conclude that XAFS measurements are a powerful way to study the Mo burial pathway in sediments and enhance our ability to infer past environmental conditions from the sedimentary record.

Sub-10 nm TiO2 nanostructures are fabricated by low-pressure UV-imprinting of an organic-inorganic resist material. Post-imprint thermal annealing allows optical property tuning over a wide range of values. For instance, a refractive index higher than 2.0 and an extinction coefficient close to zero can be achieved in the visible wavelength range. Furthermore, the imprint resist material permits fabrication of crack-free nanopatterned films over large areas and is compatible for fabricating printable photonic structures.

A variety of candidate binder compositions are added to LSM. The important properties of the resulting composites, including ASR, reactivity, and adhesion to LSCF and MCO-coated 441 stainless steel are used as screening parameters. The most promising CCM/binder composites are coated onto MCO-coated 441 coupons and anode-supported button cells with LSCF cathode, and tested at 800 degrees C. It is found that a LSM-644A composite displayed excellent initial performance and promising stability. Indeed, addition of binder is found to improve bonding of the CCM layer without sacrificing CCM conductivity. (C) 2012 Elsevier BM. All rights reserved.

Currently, two technologies are commercially available in NBBs, e.g., sodium-sulfur (Na-S) battery and sodium-metal halide (ZEBRA) batteries. In this study, we investigated the combination of these two chemistries with a mixed cathode. In particular, the cathode consisted of molten NaAlCl4 as a catholyte and a mixture of Ni, NaCl and Na2S as active materials. During cycling, two reversible plateaus were observed in cell voltage profiles, which matched electrochemical reactions for Na-S and Na-NiCl2 redox couples. An irreversible reaction between sulfur species and Ni was identified during initial charge at 280 degrees C, which caused a decrease in cell capacity. The final products on discharge included Na2Sn with 1 < n < 3, which differed from that of Na2S3 in traditional Na-S battery. This novel battery demonstrated a 50% increase in energy density over ZEBRA batteries. Despite of the initial drop in cell capacity, the mixed cathode demonstrated relatively stable cycling with more than 95% of cell capacity retained over 60 cycles. Optimization of the cathode may lead to further improvements in battery performance. Published by Elsevier B.V.

Among the three investigated compositions, the eutectic one is the most homogeneous at first heating temperature, containing in the largest amounts three families of "particles'' sizes. The results show that "particles'' of different sizes exist in Al-Si melts of different compositions and that their distribution change during thermal cycles above the melting point. The microstructures can be well explained by the dissolution and branching temperatures extrapolated from density measurements. During heating up to maximum temperature large "particles'' dissolve and recombine into smaller ones. For all compositions, the melt at the maximum temperature after heating is more homogeneous. There exist a temperature T-d at which "particles'' dissolve above melting and another temperature T-b at which a molten alloy can be considered as fully homogeneous, i.e. in a true equilibrium solution state. The presented results give the background for a complete understanding of the morphology and the physical properties of Al-Si alloys of different compositions and synthesized under different conditions.

TI Identification of SNPs associated with variola virus virulence SO BIODATA MINING LA English DT Article DE Smallpox; Variola virus; Single nucleotide polymorphisms; Multifactor dimensionality reduction ID VACCINIA VIRUS; SMALLPOX VIRUS; PROTEIN AB Background: Decades after the eradication of smallpox, its etiological agent, variola virus (VARV), remains a threat as a potential bioweapon. Outbreaks of smallpox around the time of the global eradication effort exhibited variable case fatality rates (CFRs), likely attributable in part to complex viral genetic determinants of smallpox virulence. We aimed to identify genome-wide single nucleotide polymorphisms associated with CFR. We evaluated unadjusted and outbreak geographic location-adjusted models of single SNPs and two- and three-way interactions between SNPs. Findings: Using the data mining approach multifactor dimensionality reduction (MDR), we identified five VARV SNPs in models significantly associated with CFR. The top performing unadjusted model and adjusted models both revealed the same two-way gene-gene interaction. We discuss the biological plausibility of the influence of the SNPs identified these and other significant models on the strain-specific virulence of VARV. Conclusions: We have identified genetic loci in the VARV genome that are statistically associated with VARV virulence as measured by CFR. While our ability to infer a causal relationship between the specific SNPs identified in our analysis and VARV virulence is limited, our results suggest that smallpox severity is in part associated with VARV strain variation and that VARV virulence may be determined by multiple genetic loci. This study represents the first application of MDR to the identification of pathogen gene-gene interactions for predicting infectious disease outbreak severity.

Structure-activity relationship (SAR) studies and X-ray cocrystal structure analysis allowed a detailed assessment of critical and tunable structural elements. To realize the therapeutic potential of these cyclodepsipeptides, we probed the cellular effects of a novel and representative family member, symplostatin 5 (1), which attenuated the downstream cellular effects of elastase in an epithelial lung airway model system, alleviating clinical hallmarks of chronic pulmonary diseases such as cell death, cell detachment, and inflammation. This compound attenuated the effects of elastase on receptor activation, proteolytic processing of the adhesion protein ICAM-1, NF-kappa B activation, and transcriptomic changes, including the expression of pro-inflammatory cytokines IL1A, IL1B, and IL8. Compound 1 exhibited activity comparable to the clinically approved elastase inhibitor sivelestat in short-term assays and demonstrated superior sustained activity in longer-term assays.

TI Molecular dynamics simulations of evaporation-induced nanoparticle assembly SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID WATER-AIR INTERFACE; COLLOIDAL CRYSTALS; NANOCRYSTAL SUPERLATTICES; NANOCLUSTERS; TRANSITION; MONOLAYERS AB While evaporating solvent is a widely used technique to assemble nano-sized objects into desired superstructures, there has been limited work on how the assembled structures are affected by the physical aspects of the process. We present large scale molecular dynamics simulations of the evaporation-induced assembly of nanoparticles suspended in a liquid that evaporates in a controlled fashion. The quality of the nanoparticle crystal formed just below the liquid/vapor interface is found to be better at relatively slower evaporation rates, as less defects and grain boundaries appear. This trend is understood as the result of the competition between the accumulation and diffusion times of nanoparticles at the liquid/vapor interface. When the former is smaller, nanoparticles are deposited so fast at the interface that they do not have sufficient time to arrange through diffusion, which leads to the prevalence of defects and grain boundaries. Our results have important implications in understanding assembly of nanoparticles and colloids in non-equilibrium liquid environments. (C) 2013 American Institute of Physics.

A complete accounting for electrostatic contributions to the heat flux was found to resolve the previously reported differing results of NEMD and EMD Green-Kubo measurements for the extended simple point-charge (SPC/E) model. Accordingly, we demonstrate the influence of long-range electrostatics on the thermal conductivity with a simple coulomb cutoff, Ewald summation, and by an extended particle-particle particle-mesh method. For each water model, the thermal conductivity is computed and decomposed in terms of frequency-dependent thermodynamic and topological contributions. The rigid, three-site SPC, SPC/E, and transferable intermolecular potential (TIP3P-Ew) water models are shown to have similar thermal conductivity values at standard conditions, whereas models that include bond stretching and angle bending have higher thermal conductivities.

The C-beta-C-gamma bond cleavage of a C-terminal decarboxylated tryptophan residue ([M - CO2](center dot+)) can generate [M - CO2 - 116](+), [M - CO2 - 117](center dot+), and [1H-indole](center dot+) (m/z 117) species as possible product ions. Competition between the formation of [M - CO2 - 116](+) and [1H-indole](center dot+) systems implies the existence of a proton-bound dimer formed between the indole ring and peptide backbone. Formation of such a proton-bound dimer is facile via a protonation of the tryptophan gamma-carbon atom as suggested by density functional theory (DFT) calculations. DFT calculations also suggested the initially formed ion 2, the decarboxylated species that is active against C-beta-C-gamma. bond cleavage, can efficiently isomerize to form a more stable pi-radical isomer (ion 9) as supported by Rice-Ramsperger-Kassel-Marcus (RRKM) modeling. The C-beta-C-gamma bond cleavage of a tryptophan residue also can occur directly from peptide radical cations containing a basic residue. CID of [WG(n)R](center dot+) (n = 1-3) radical cations consistently resulted in predominant formation of [M - 116](+) product ions. It appears that the basic arginine residue tightly sequesters the proton and allows the charge-remote C-beta-C-gamma bond cleavage to prevail over the charge-directed one. DFT calculations predicted that the barrier for the former is 6.2 kcal mol(-1) lower than that of the latter. Furthermore, the pathway involving a salt-bridge intermediate also was accessible during such a bond cleavage event.

The arrangements of nanoparticles within the films were analyzed using the technique of Voronoi tessellations. These analyses indicated that the films possessed equivalent degrees of ordering, and that the films were uniform over centimeter length scales. Precise measurements of the interparticle spacing were obtained, and the magnitudes of magnetic dipole interactions were calculated. The dipole-dipole interaction among the larger nanoparticles was 14 times larger than that of the smaller nanoparticles, indicating that magnetic coupling interactions could not have been the lone source of ordering in the system.

TI Electrophoretic Deposition of Thermites onto Micro-Engineered Electrodes Prepared by Direct-Ink Writing SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID ENERGETIC COMPOSITES; REACTION PROPAGATION; CODEPOSITION; AL/MOO3; AL/CUO AB This work combines electrophoretic deposition (EPD) with direct-ink writing (DIW) to prepare thin films of Al/CuO thermites onto patterned two- and three-dimensional silver electrodes. DIW was used to write the electrodes using a silver nanoparticle ink, and EPD was performed in a subsequent step to deposit the thermite onto the conductive electrodes. Unlike conventional lithographic techniques, DIW is a low-cost and versatile alternative to print fine-featured electrodes, and adds the benefit of printing self-supported three-dimensional structures. EPD provides a method for depositing the composite thermite only onto the conductive electrodes, and with controlled thicknesses, which provides fine spatial and mass control, respectively. EPD has previously been shown to produce well-mixed thermite composites which can pack to reasonably high densities without the need for any postprocessing. Homogeneous mixing is particularly important in reactive composities, where good mixing can enhance the reaction kinetics by decreasing the transport distance between the components. Several two- and three-dimensional designs were investigated to highlight the versatility of using DIW and EPD together. In addition to energetic applications, we anticipate that this combination of techniques will have a variety of other applications, which would benefit from the controlled placement of a thin film of one material onto a conductive architecture of a second material.

TI Morphology of Electrophoretically Deposited Films on Electrode Strips SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID LAYERS; COATINGS; BIOMATERIALS; FABRICATION; MEMBRANE; KINETICS; EPD AB Studies of the kinetics of electrophoretic deposition (EPD) processes have generally focused on electrode geometries that yield analytical solutions, such as infinite parallel planes and concentric cylinders. In this article, we construct a finite element model for EPD of material onto a planar strip electrode, which shows excellent qualitative agreement to experimental results in a similar system. Notably, we demonstrate that the presence of the edges of the electrode lead to a singularity in the electric field that significantly affects the morphology of the deposit at short times or for thin deposits.

TI Effects of Electronic and Nuclear Interactions on the Excited-State Properties and Structural Dynamics of Copper(I) Diimine Complexes SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID ABSORPTION FINE-STRUCTURE; EXTENDED X-RAY; REGULAR 2-COMPONENT HAMILTONIANS; TRANSIENT MOLECULAR-STRUCTURES; SENSITIZED SOLAR-CELLS; CHARGE-TRANSFER; PHOTOPHYSICAL PROPERTIES; COORDINATION-COMPOUNDS; BIS-PHENANTHROLINE; METAL-COMPLEXES AB The effects of structural constraints on the metal-to-ligand charge transfer (MLCT) excited state structural dynamics of cuprous bis-2,9-diphenyl-phenanthroline ([Cu(I)(dpp)(2)](+)) in both coordinating acetonitrile and noncoordinating toluene were studied using X-ray transient absorption (XTA) spectroscopy and density functional theory (DFT) calculations. The phenyl groups attached to the phenanthroline ligands not only effectively shield the Cu(I) center from solvent molecules, but also force a flattened tetrahedral coordination geometry of the Cu(I) center. Consequently, the MLCT state lifetime in [Cu(I)(dpp)(2)](+) is solvent-independent, unlike the previously studied 2,9-methyl substituted bis-phenanthroline Cu(I) complex. The MLCT state of [Cu(I)(dpp)(2)](+) still undergoes a "pseudo Jahn-Teller distortion," with the angle between the two phenanthroline ligand planes decreased further by 7 degrees The XTA results indicate that, in the MLCT excited state of [Cu(I)(dpp)(2)](+), the phenyls at the 2, 9 positions of the phenanthroline rotate, breaking the pi-pi interaction with the phenanthroline ligands without ever rotating in-plane with the phenanthroline ligands. Hence, the transferred electron density from the Cu(I) center is localized on the phenanthroline moiety with no charge density present on the phenyl rings. The insight about the effect of the structural constraints on the MLCT state properties will guide the design of Cu(I) diimine complexes with suitable excited-state properties to function as earth-abundant dye sensitizers for solar electricity generation.

These NMR diffusion results were combined with previously measured rotational diffusion coefficients (D-R) obtained from N-14 NMR relaxation measurements for the same ILs (Alam, T. M.; et al. J. Phys. Chem. A 2011, 115, 4307-4316). The D-T/D-R ratio was then used to estimate the effective hydrodynamic radius and corresponding volumes without the need to directly measure the viscosities of the ILs. The generality, validity, and performance of using this D-T/D-R ratio is discussed and compared to the effective hydrodynamic volumes obtained using classic D-T/viscosity and D-R/viscosity relationships. The temperature variation observed for the molecular volumes obtained using the D-T/D-R ratio is argued to be a signature for the breakdown or decoupling of the Stokes-Einstein and Stoke-Einstein-Debye relationships in these neat IL systems, consistent with recent molecular dynamic simulations.

As part of our effort to develop a cost-effective regeneration pathway for AlH3, we report the synthesis and characterization of N-alkylpyrrolidine center dot alane complexes (NMPy)(2)center dot AlH3, NMPy center dot AlH3, and NEPy center dot AlH3 (NMPy = N-methylpyrrolidine, NEPy = N-ethylpyrrolidine); the reversible formation of (NMPy)(2)center dot AlH3 from titanium-doped aluminum metal (denoted as Al*), H-2 gas, and NMPy; and thermal decomposition studies of these alane adducts. Depending on the stoichiometric ratios of NMPy to AlH3, both the 2:1 complex (NMPy)(2)center dot AlH3 and the 1:1 complex NMPy center dot AlH3 can be selectively synthesized by direct reactions of NMPy with AlH3, whereas NEPy gives only the 1:1 adduct NEPy center dot AlH3 regardless of the ratio of NEPy to AlH3. In addition, the reversible formation of (NMPy)(2)center dot AlH3 from titanium-doped aluminum powder (Al*) and NMPy under a H-2 pressure of 1000 psi was observed, while no alane formation was detected with NEPy. Theoretical calculations of the molecular geometries and absolute free energies are in good agreement with experimental observations, and indicate that the dramatic differences between NMPy and NEPy are caused by the steric effects imposed by the alkyl group (methyl or ethyl) on the pyrrolidine ring. Finally, we established the role of LiH in the decomposition of amine center dot alane adducts, and showed that the hydrogenation of Al* with NMPy and the decomposition of N-alkylpyrrolidine center dot alane adducts in the presence of LiH could be combined to generate donor-free LiAlH4.

The discharge products of Li-O-2 reactions were analyzed by X-ray diffraction, X-ray photoelectron spectroscopy, and nuclear magnetic resonance spectroscopy. The performance of Li-O-2 batteries was strongly affected by the salt used in the electrolyte. Lithium tetrafluoroborate (LiBF4) and lithium bis(oxalato)borate (LiBOB) decomposed and formed LiF and lithium oxalate, respectively, as well as lithium borates during discharge of Li-O-2 batteries. In the case of other salts, including lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), lithium trifluoromethanesulfonate (LiTf), lithium hexafluorophosphate (LiPF6), lithium perchlorate (LiClO4), and lithium bromide (LiBr), the discharge products mainly consisted of Li2O2 and carbonates with minor signs of decomposition of LiTFSI, LiTf, and LiPF6. LiBr and LiClO4 showed the best stability during the discharge process. For the cycling performance, LiTf and LiTFSI were the best among the studied salts. In addition to the instability of lithium salts, decomposition of tetraglyme solvent was a more significant factor contributing to the limited cycling stability. Thus, a more stable nonaqueous electrolyte including organic solvent and lithium salt still needs to be further developed to reach a fully reversible Li-O-2 battery.

The uptake of molecular water and hydroxyl species on the (001) surface of a natural magnetite sample at near-ambient conditions was quantified using O Is spectra taken in the p(H2O) range from 10(-9) to 2 Torr. At low p(H2O) (<= 10(-4)-10(-s) Torr) and room temperature, we found that water does not adsorb dissociatively on the surface, except on defect sites. In contrast, progressive dissociation into surface hydroxyl species was observed between 10(-4) and 10(-2) Torr p(H2O). The onset of hydroxylation coincides with the increasing presence of molecular water species on the surface, which demonstrates the key role played by cooperative interactions between adsorbed water molecules, leading to dissociation and surface hydroxylation. The measured O Is chemical shifts of hydroxyl and molecular water species from both isotherm and isobar data are on average similar to 1.2 eV and similar to 3.3 eV, respectively, relative to lattice oxygen. The chemical shift of the hydroxyl species on magnetite(001) agrees with previously reported values for hydroxyl species on iron oxyhydroxides such as goethite (alpha-FeOOH). DFT calculations including an on-site Coulomb repulsion parameter (generalized gradient approximation (GGA) + U approach) predict O Is surface core-level shifts (SCLS) at the clean (2(1/2)X2(1/2))R45 degrees reconstructed Fe3O4(001) surface of up to similar to-1 eV depending on the specific bonding configuration of the surface O atoms. Hydroxyl groups formed by the dissociation of isolated water molecules at 0 vacancies have an SCLS value of similar to 1.2 eV. With increasing coverage there is a transition toward partial dissociation on the (001) surface. The calculated SCLS for hydroxyl and adsorbed water are 1.2-1.9 and 2.6-3.0 eV, respectively, and compare very well with our experimental results. Final-state effects obtained within the Slater-Janak approach thus have the dominant contribution. In addition, the modest reduction of the work function (similar to 0.5 eV) predicted by DFT calculations for the mixed adsorption of dissociated and intact water molecules agrees well with work function changes measured experimentally. Finally, the similarity between isotherm and isobar data and the DFT calculations for the C-free Fe3O4(001) surface indicate that surface hydroxylation is indeed substrate induced and not catalyzed by the presence of adventitious carbonaceous species. Both theory and experiment show the importance of cooperative effects between adjacent water molecules in the dissociation reaction. C1 [Kendelewicz, T.; Brown, G.

High-pressure scanning tunneling microscopy shows that the hexagonal reconstruction on the clean Pt(100) surface is preserved under 1 Torr of C2H4, which produces an ethylidyne and di-sigma-bonded ethylene saturated surface. At 5 X 10(-6) Tort of C2H4, coadsorbed CO from the background gases lifts the reconstruction, with the excess Pt atoms from the hexagonal surface forming islands on the surface. The chemisorption of CO from background gases in the vacuum system, in the nominally pure C2H4, is revealed by ambient-pressure X-ray photoelectron spectroscopy.

TI A High-Resolution Enhancer Atlas of the Developing Telencephalon SO CELL LA English DT Article ID TRANSCRIPTION FACTOR-BINDING; RECOMBINASE ACTIVITY; BRAIN-DEVELOPMENT; RANDOM FORESTS; EXPRESSION; SCHIZOPHRENIA; DATABASE; AUTISM; CHROMOSOMES; ASSOCIATION AB The mammalian telencephalon plays critical roles in cognition, motor function, and emotion. Though many of the genes required for its development have been identified, the distant-acting regulatory sequences orchestrating their in vivo expression are mostly unknown. Here, we describe a digital atlas of in vivo enhancers active in subregions of the developing telencephalon. We identified more than 4,600 candidate embryonic forebrain enhancers and studied the in vivo activity of 329 of these sequences in transgenic mouse embryos. We generated serial sets of histological brain sections for 145 reproducible forebrain enhancers, resulting in a publicly accessible web-based data collection comprising more than 32,000 sections. We also used epigenomic analysis of human and mouse cortex tissue to directly compare the genome-wide enhancer architecture in these species. These data provide a primary resource for investigating gene regulatory mechanisms of telencephalon development and enable studies of the role of distant-acting enhancers in neurodevelopmental disorders.

The oxygen stoichiometry in the films was varied by changing the oxygen partial pressure P(O-2) during the deposition process. For SrRuO3 films with P(O-2) >= 60 mTorr, they exhibited a pseudo-orthorhombic structure with in-plane uniaxial magnetic anisotropy. On the other hand for films with P(O-2) <= 45 mTorr, the tetragonal SrRuO3 phase with a perpendicular uniaxial magnetic anisotropy was stabilized at room temperature. The big difference in the magnetic anisotropy of these two SrRuO3 phases was shown to be closely linked to their respective RuO6 octahedral rotation patterns: the RuO6 octahedra rotate differently along the two orthogonal in-plane directions in the pseudo-orthorhombic phase, whereas in the tetragonal phase only octahedral rotations around z-axis are present and the octahedral tilts along the in-plane axes are diminished. First-principles calculations show that such a suppression of the RuO6 octahedra tilting in the tetragonal phase arises from the oxygen vacancies at the octahedral apex (along z-axis). This work demonstrates that the stoichiometry plays an important role in determining the octahedral rotations and tilts in the perovskite materials, which may induce new phases with distinctively different structural symmetry and physical property.

Samples with excess oxygen exhibit spin glass behavior without long-range magnetic order, while three-dimensional ferrimagnetic order exists in a stoichiometric sample. Dissimilar experimental observations reported in several papers can be understood consistently when oxygen stoichiometry is taken into account. The stoichiometric sample orders magnetically below T-N - 243K, and a monoclinic lattice distortion sets in below T-L - 175K. This structural change is sensitive to the applied magnetic field, indicating strong spin-lattice coupling in this material. Unusual low-field thermal magnetization behavior was observed near T-L, and its origin is discussed. (C) 2013 American Institute of Physics.

The long relaxation times, two orders of magnitude longer than in paraffin-(alkane-) coated cells, motivate revisiting the question of what the mechanism is underlying wall-collision-induced relaxation and renew interest in applications of alkali-metal vapor cells to secondary frequency standards. We measure the width and frequency shift of the ground-state hyperfine m(F) = 0 -> m'(F) = 0 transition (clock resonance) in vapor cells with Rb-85 and Rb-87 atoms, with an alkene antirelaxation coating. We find that the frequency shift is slightly larger than for paraffin-coated cells and that the Zeeman linewidth scales linearly with the hyperfine frequency shift.

TI Numerical Modeling of the Sensitivity of X-Ray Driven Implosions to Low-Mode Flux Asymmetries SO PHYSICAL REVIEW LETTERS LA English DT Article ID NATIONAL IGNITION FACILITY; COMPRESSION; TARGETS; MATTER AB The sensitivity of inertial confinement fusion implosions, of the type performed on the National Ignition Facility (NIF) [1], to low-mode flux asymmetries is investigated numerically. It is shown that large-amplitude, low-order mode shapes (Legendre polynomial P-4), resulting from low-order flux asymmetries, cause spatial variations in capsule and fuel momentum that prevent the deuterium and tritium (DT) "ice" layer from being decelerated uniformly by the hot spot pressure. This reduces the transfer of implosion kinetic energy to internal energy of the central hot spot, thus reducing the neutron yield. Furthermore, synthetic gated x-ray images of the hot spot self-emission indicate that P-4 shapes may be unquantifiable for DT layered capsules. Instead the positive P-4 asymmetry "aliases" itself as an oblate P-2 in the x-ray images. Correction of this apparent P-2 distortion can further distort the implosion while creating a round x-ray image. Long wavelength asymmetries may be playing a significant role in the observed yield reduction of NIF DT implosions relative to detailed postshot two-dimensional simulations.

However, direct evidence for the development of the Kondo coherent state and for the evolution of the electronic structure in the material has not been obtained due to the compound's rather complicated electronic and thermal transport behavior. Recently, these open questions have attracted increasing attention as the emergence of a time-reversal-invariant topological surface state in the Kondo insulator has been suggested. Here, we use point-contact spectroscopy to reveal the temperature dependence of the electronic states in SmB6. We demonstrate that SmB6 is a model Kondo insulator: Below 100 K, the conductance spectra reflect the Kondo hybridization of Sm ions, but, below about 30 K, signatures of inter-ion correlation effects clearly emerge. Moreover, we find evidence that the low-temperature insulating state of this exemplary Kondo-lattice compound harbors conduction states on the surface, in support of predictions of nontrivial topology in Kondo insulators.

TI Complex crystallization dynamics in amorphous germanium observed with dynamic transmission electron microscopy SO PHYSICAL REVIEW B LA English DT Article ID EXPLOSIVE CRYSTALLIZATION; GE FILMS; IN-SITU; PHASE-TRANSFORMATIONS; LASER IRRADIATION; THIN-FILMS; SILICON; DTEM; HEAT; TEM AB Crystallization of amorphous germanium (a-Ge) by laser or electron beam heating is a remarkably complex process that involves several distinct modes of crystal growth and the development of intricate microstructural patterns on the nanosecond to ten microsecond time scales. Here we use dynamic transmission electron microscopy (DTEM) to study the fast, complex crystallization dynamics with 10 nm spatial and 15 ns temporal resolution. We have obtained time-resolved real-space images of nanosecond laser-induced crystallization in a-Ge with unprecedentedly high spatial resolution. Direct visualization of the crystallization front allows for time-resolved snapshots of the initiation and roughening of the dendrites on submicrosecond time scales. This growth is followed by a rapid transition to a ledgelike growth mechanism that produces a layered microstructure on a time scale of several microseconds. This study provides insights into the mechanisms governing this complex crystallization process and is a dramatic demonstration of the power of DTEM for studying time-dependent material processes far from equilibrium.

Chemically synthesized Ni nanoparticles were used as the catalyst for growth. The Si-containing coating (SiNx) typically created when VACNFs are grown on silicon was produced by adding Si microparticles prior to growth. The fiber arrays were transferred to PDMS by spin coating a layer on the grown substrates, curing the PDMS, and etching away the Al in KOH. The fiber arrays contain many fibers over 15 pm (long enough to protrude from the PDMS film and penetrate cell membranes) and SiNx coatings as observed by SEM, EDX, and fluorescence microscopy. The free-standing array in PDMS was loaded with pVENUS-C-1 plasmid and human brain microcapillary endothelial (HBMEC) cells and was successfully impalefected.

We replaced the iron(III)-binding motif with a lanthanide-binding peptide sequence that is known to selectively recognize trivalent lanthanide ions. The newly engineered two-component system (PmrA/PmrB) can effectively sense lanthanide ion and regulate gene expression in E. coli. This work not only provides the first known lanthanide-based sensing and response in live cells but also demonstrates that the PmrA/PmrB system is a suitable template for future synthetic biology efforts to construct bacteria that can sense and respond to other metal ions in remediation or sequestration.

TI Colocalized Delivery of Adjuvant and Antigen Using Nanolipoprotein Particles Enhances the Immune Response to Recombinant Antigens SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID MICE AB Subunit antigen-based vaccines can provide a number of important benefits over traditional vaccine candidates, such as overall safety. However, because of the inherently low immunogenicity of these antigens, methods for colocalized delivery of antigen and immunostimulatory molecules (i.e., adjuvants) are needed. Here we report a robust nanolipoprotein particle (NLP)-based vaccine delivery platform that facilitates the codelivery of both subunit antigens and adjuvants. Ni-chelating NLPs (NiNLPs) were assembled to incorporate the amphipathic adjuvants monophosphoryl lipid A and cholesterol-modified CpG oligodeoxynucleotides, which can bind His-tagged protein antigens. Colocalization of antigen and adjuvant delivery using the NiNLP platform resulted in elevated antibody production against His-tagged influenza hemagglutinin 5 and Yersinia pestis LcrV antigens. Antibody titers in mice immunized with the adjuvanted NLPs were 5-10 times higher than those observed with coadministration formulations and nonadjuvanted NiNLPs. Colocalized delivery of adjuvant and antigen provides significantly greater immune stimulation in mice than coadministered formulations.

We report an intermolecular asymmetric addition of the C-H bonds of indoles, thiophenes, pyrroles, and furans to bicycloalkenes in high yield with high enantiomeric excess. These heteroarene alkylations occur ortho to the heteroatom. This selectivity is observed even with unprotected indoles, which typically undergo alkylation at the C3 position. Initial mechanistic studies revealed that oxidative addition of a heteroarene C-H bond to a neutral species occurs within minutes at room temperature and occurs in the catalytic cycle prior to the turnover-limiting step. Products from syn addition of the C-H bond across the olefin were observed. C1 [Hartwig, John F.] Univ Calif Berkeley, Lawrence Berkeley Natl Lab, Div Chem Sci, Berkeley, CA 94720 USA.

This species was created through charge transfer from an iodide anion within a binary iodide-uracil complex using a UV pump pulse; the ensuing dynamics were followed by photodetachment with a near-IR probe pulse. The photoelectron spectra show two time-dependent features, one from probe-induced photodetachment of the transient anion state and another from very low energy electron signal attributed to autodetachment. The transient anion was observed to decay biexponentially with time constants of hundreds of femtoseconds and tens of picoseconds, depending on the excitation energy. These dynamics are interpreted in terms of autodetachment from the initially excited state and a second, longer-lived species relaxed by iodine loss. Hydrogen loss from the N1 position may also occur in parallel. C1 [Yandell, Margaret A.; King, Sarah B.; Neumark, Daniel M.] Univ Calif Berkeley, Dept Chem, Berkeley, CA 94720 USA.

The modularity of our approach facilitates the fabrication of asymmetric nanostructures with varying sizes, shapes, compositions, surface chemistry, and surface hydrophobicity.

The majority of CO molecules adsorb molecularly on the surface of the nanoparticles, but some undergo dissociative adsorption, leading to oxide species on the surface of the nanoparticles. We found that the tendency of CO to undergo dissociation depends critically on the size of the Co nanoparticles. Indeed, CO molecules dissociate much more efficiently on the larger nanoparticles (15 nm) than on the smaller particles (4 nm). We further observed a strong increase in the dissociation rate of adsorbed CO upon exposure to hydrogen, clearly demonstrating that the CO dissociation on cobalt nanoparticles is assisted by hydrogen. Our results suggest that the ability of cobalt nanoparticles to dissociate hydrogen is the main parameter determining the reactivity of cobalt nanoparticles in Fischer-Tropsch synthesis.

In general, these compounds can be prepared from U(NR)(2)I-2(THF)(x) (x = 2 and R = 'Bu, Ph; x = 3 and R = Me) upon addition of excess halide. In addition to providing stable coordination complexes with Cl-, the [U(NMe)(2)](2 +) cation also reacts with Br- to form stable [NEt4](2)[U(NMe)(2)Br-4] complexes. These materials were used as a platform to compare electronic structure and bonding in [U(NR)(2)](2+) with [UO2](2+). Specifically, Cl K-edge X-ray absorption spectroscopy (XAS) and both ground-state and time-dependent hybrid density functional theory (DFT and TDDFT) were used to probe U-Cl bonding interactions in [PPh4](2)[U((NBu)-Bu-t)(2)Cl-4] and [PPh4](2)[UO2Cl4]. The DFT and XAS results show the total amount of Cl 3p character mixed with the U 5f orbitals was roughly 7-10% per U-Cl bond for both compounds, which shows that moving from oxo to imido has little effect on orbital mixing between the U 5f and equatorial Cl 3p orbitals. The results are presented in the context of recent Cl K-edge XAS and DFT studies on other hexavalent uranium chloride systems with fewer oxo or imido ligands.

First, two molecules that differ only in the position of a pyridyl N-atom within an acceptor fragment are compared and contrasted. X-ray investigation of single crystals reveals that positioning the pyridyl N-atoms proximal to the molecules center changes the molecular shape by bending the molecule into a banana shape. Second, we demonstrate that the banana shape of the molecule can be controlled by replacing a Si atom within the dithienosilole fragment with a C or Ge atom. Here, utilization of cyclopentadithiophene or dithienogermole as the internal electron-rich unit leads to a decrease or an increase in the bending of the conjugated backbone, respectively. Such molecular shape changes alter intermolecular packing and thus affect bulk properties, leading to large differences in the optical, thermal, and crystallization properties.

TI Sensitivity of force-detected NMR spectroscopy with resonator-induced polarization SO PHYSICAL REVIEW B LA English DT Article ID MULTIPLE SPIN ECHOES; MAGNETIC-RESONANCE; DIPOLAR SOLIDS; NOISE; EUO; MICROSCOPY; LOCKING; SYSTEMS; ENHANCEMENT; RELAXATION AB In the low-temperature regime where the thermal polarization P is of order unity and spin-lattice relaxation is "frozen out," resonator-induced relaxation can be used to polarize a nuclear-spin sample for optimal detection sensitivity. We characterize the potential of resonator-induced polarization for enhancing the sensitivity of nuclear-magnetic-resonance spectroscopy. The sensitivities of two detection schemes are compared, one involving detection of a polarized sample dipole and the other involving detection of spin-noise correlations in an unpolarized sample. In the case where the dominant noise source is instrument noise associated with resonator fluctuations and with detection of the mechanical motion, a simple criterion can be used to compare the two schemes. Polarizing the sample improves sensitivity when P is larger than the signal-to-noise ratio for detection of a fully-polarized spin during a single transient. Even if the instrument noise is decreased to a level near the quantum-mechanical limit, it is larger than spin noise for unpolarized samples containing up to a few tens of nuclei. Under these conditions, spin polarization of order unity would enhance spectroscopic detection sensitivity by an order of magnitude or more. In the limiting case where signal decay is due to resonator-induced dissipation during ideal spin locking, and where resonator fluctuations are the noise source, the only parameter of the spin-resonator system that affects the sensitivity per spin is the ratio of frequency to temperature. A balance between the coupling strength, the noise power, and the signal lifetime causes the cancellation of other parameters from the sensitivity formula. Partial cancellation of parameters, associated with a balance between the same three quantities, occurs more generally when the resonator is both the dominant noise source and the dominant source of signal decay. An intrinsic sensitivity limit exists for resonant detection of coherent spin evolution, due to the fact that the detector causes signal decay by enhancing the spins' spontaneous emission. For a single-spin sample, the quantum-limited signal-to-noise ratio for resonant detection is 1/3. In contrast to the sensitivity, the time required for sample polarization between transients depends strongly on resonator parameters. We discuss resonator design and show that for a torsional resonator, the coupling is optimal when the resonator's magnetization remains aligned with the applied field during the mechanical oscillations.

TI Two-dimensional quantum diffusion of Gd adatoms in nano-size Fe corrals SO PHYSICAL REVIEW B LA English DT Article ID AG ISLANDS; SURFACE; GROWTH; CONFINEMENT; AG(111); FILMS AB Gd atom diffusion in 30-nm-diameter Fe quantum corrals is studied utilizing scanning tunneling microscopy and kinetic Monte Carlo (KMC) simulations. The Gd adatom probability distribution inside the corral forms several trajectories and is closely related to oscillations of the local density of states at the Fermi level, as revealed by spectroscopy measurements. With increasing coverage, the Gd adatoms form a ringlike structure within the vicinity of the quantum corrals. The results are explained with KMC calculations utilizing experimentally determined long-range interactions and quantum confinement. The findings demonstrate that the diffusion of Gd adatoms is significantly influenced by the quantum corrals and that novel quantum ring structures can be created via control of the coverage.

The surfaces were prepared by cleaving single-crystal samples in situ under UHV conditions. Diffraction measurements in the region around the He specular reflection angle soon after cleaving yielded specular peaks initially with broad shoulders. However, over a period of about an hour, the shoulders diminished into the background. Drift spectra measurements of the stabilized surfaces revealed that the step heights separating surface terraces were predominantly multiples of the approximately 4-angstrom unit-cell dimension rather than multiples of the approximately 2-angstrom half-unit-cell dimension expected from the cleaving of these crystals. Together, these results suggest that these surfaces are rapidly modified after cleaving by migration of ions to the surface from the near surface. Further, half-order diffraction peaks were observed in the < 100 > azimuth a short time after cleaving samples at room temperature, indicating that domains with (2 x 1) structure had formed.

Surveying the series of 3d oxides within a typical GW approach using the random-phase approximation reveals mixed results, including cases where the calculated band gap is either too small or too large, depending on the oxidation states of the TM (e. g., FeO/Fe2O3, Cu2O/CuO). The problem appears to originate mostly from a too high average d-orbital energy, whereas the splitting between occupied and unoccupied d symmetries seems to be reasonably accurate. It is shown that augmenting the GW self-energy by an attractive (negative) and occupation-independent on-site potential for the TM d orbitals with a single parameter per TM cation can reconcile the band gaps for different oxide stoichiometries and TM oxidation states. In Cu2O, which is considered here in more detail, standard GW based on wave functions from initial density or hybrid functional calculations yields an unphysical prediction with an incorrect ordering of the conduction bands, even when the magnitude of the band gap is in apparent agreement with experiment. The correct band ordering is restored either by applying the d-state potential or by iterating the wave functions to self-consistency, which both have the effect of lowering the Cu-d orbital energy. While it remains to be determined which improvements over standard GW implementations are needed to achieve an accurate ab initio description for a wide range of transition metal compounds, the application of the empirical on-site potential serves to mitigate the problems specifically related to d states in GW calculations.

The cross sections were internally standardized using a stoichiometric KCl target with well-known Cl-35(n,gamma) gamma-ray cross sections [Revay and Molnar, Radiochimica Acta 91, 361 (2003); Molnar, Revay, and Belgya, Nucl. Instrum. Meth. Phys. Res. B 213, 32 (2004)]. These data were combined with gamma-ray intensities from von Egidy et al.

Total radiative neutron cross sections were deduced from the total gamma-ray cross section feeding the ground state, sigma(0) = Sigma sigma(gamma)(GS) after correction for unobserved statistical gamma-ray feeding from levels near the neutron capture energy. The corrections were performed with Monte Carlo simulations of the potassium thermal neutron capture decay schemes using the computer code DICEBOX where the simulated populations of low-lying levels are normalized to the measured cross section depopulating those levels. Comparisons of the simulated and experimental level feeding intensities have led to proposed new spins and parities for selected levels in the potassium isotopes where direct reactions are not a significant contribution. We determined the total radiative neutron cross sections sigma(0)(K-39) = 2.28 +/- 0.04 b, sigma(0)(K-40) = 90 +/- 7 b, and sigma(0)(K-41) = 1.62 +/- 0.03 b from the prompt gamma-ray data and the gamma-ray transition probability P-gamma (1524.66) = 0.164(4) in the beta(-) decay of K-42 in a low-background counting experiment.

CA MINOS Collaboration TI Comparisons of annual modulations in MINOS with the event rate modulation in CoGeNT SO PHYSICAL REVIEW D LA English DT Article ID DARK-MATTER CANDIDATES; DAMA/LIBRA AB The CoGeNT Collaboration has recently published results from a fifteen month data set which indicate an annual modulation in the event rate similar to what is expected from weakly interacting massive particle interactions. It has been suggested that the CoGeNT modulation may actually be caused by other annually modulating phenomena, specifically the flux of atmospheric muons underground or the radon level in the laboratory. We have compared the phase of the CoGeNT data modulation to that of the concurrent atmospheric muon and radon data collected by the MINOS experiment which occupies an adjacent experimental hall in the Soudan Underground Laboratory. The results presented are obtained by performing a shape-free chi(2) data-to-data comparison and from a simultaneous fit of the MINOS and CoGeNT data to phase-shifted sinusoidal functions. Both tests indicate that the phase of the CoGeNT modulation is inconsistent with the phases of the MINOS muon and radon modulations at the 3.0 sigma level.

TI Transport properties of lithium hydride at extreme conditions from orbital-free molecular dynamics SO PHYSICAL REVIEW E LA English DT Article ID BINARY IONIC MIXTURES; INTERDIFFUSION; DIFFUSION; PLANETS; PLASMAS; ENERGY; MODELS AB We have performed a systematic study of lithium hydride (LiH), using orbital-free molecular dynamics, with a focus on mass transport properties such as diffusion and viscosity by extending our previous studies at the lower end of the warm, dense matter regime to cover a span of densities from ambient to 10-fold compressed and temperatures from 10 eV to 10 keV. We determine analytic formulas for self-and mutual-diffusion coefficients, and viscosity, which are in excellent agreement with our molecular dynamics results, and interpolate smoothly between liquid and dense plasma regimes. In addition, we find the orbital-free calculations begin to agree with the Brinzinskii-Landau formula above about 250 eV at which point the medium becomes fully ionized. A binary-ion model based on a bare Coulomb interaction within a neutralizing background with the effective charges determined from a regularization prescription shows good agreement above about 100 eV with the orbital-free results. Finally, we demonstrate the validity of a pressure-based mixing rule in determining the transport properties from the pure-species quantities.

TI Spatially resolved analysis of K alpha x-ray emission from plasmas induced by a femtosecond weakly relativistic laser pulse at various polarizations SO PHYSICAL REVIEW E LA English DT Article ID FAST-ELECTRON TRANSPORT; MAGNETIC-FIELDS; SOLID INTERACTIONS; ATOMIC MODELS; DENSE-PLASMA; INTENSITY; ABSORPTION; RADIATION; ACCELERATION; GENERATION AB Spatially resolved K-shell spectroscopy is used here to investigate the interaction of an ultrashort laser pulse (lambda = 800 nm, tau = 40 fs) with a Ti foil under intense irradiation (I lambda(2) = 2 x 10(18) W mu m(2) cm(-2)) and the following fast electron generation and transport into the target. The effect of laser pulse polarization (p, s, and circular) on the K alpha yield and line shape is probed. The radial structure of intensity and width of the lines, obtained by a discretized Abel deconvolution algorithm, suggests an annular distribution of both the hot electron propagation into the target and the target temperature. An accurate modeling of K alpha line shapes was performed, revealing temperature gradients, going from a few eV up to 15-20 eV, depending on the pulse polarization. Results are discussed in terms of mechanisms of hot electron generation and of their transport through the preplasma in front of the target.

TI Modeling the polydomain-monodomain transition of liquid crystal elastomers SO PHYSICAL REVIEW E LA English DT Article ID GAY-BERNE FLUID; NEMATIC ELASTOMERS; PHASE-BEHAVIOR; LATTICE MODEL; SIMULATION; DEFORMATION; DYNAMICS; DISORDER; MUSCLE; FIELD AB We study the mechanism of the polydomain-monodomain transition in liquid crystalline elastomers at the molecular scale. A coarse-grained model is proposed in which mesogens are described as ellipsoidal particles. Molecular dynamics simulations are used to examine the transition from a polydomain state to a monodomain state in the presence of uniaxial strain. Our model demonstrates soft elasticity, similar to that exhibited by side-chain elastomers in the literature. By analyzing the growth dynamics of nematic domains during uniaxial extension, we provide direct evidence that at a molecular level the polydomain-monodomain transition proceeds through cluster rotation and domain growth.

CA CDF Collaboration TI Observation of the Production of a W Boson in Association with a Single Charm Quark SO PHYSICAL REVIEW LETTERS LA English DT Article ID PARTON DISTRIBUTIONS; SIMULATION; LHC AB The first observation of the production of a W boson with a single charm quark (c) jet in p (p) over bar collisions at root s = 1.96 TeV is reported. The analysis uses data corresponding to 4.3 fb(-1), recorded with the CDF II detector at the Fermilab Tevatron. Charm quark candidates are selected through the identification of an electron or muon from charm-hadron semileptonic decay within a hadronic jet, and a Wc signal is observed with a significance of 5.7 standard deviations. The production cross section sigma(Wc) (p(Tc) > 20 GeV/c, vertical bar eta(c)vertical bar < 1.5) x B(W -> l nu) is measured to be 13.6(-3.1)(+3.4) pb and is in agreement with theoretical expectations. From this result the magnitude of the quark-mixing matrix element V-cs is derived, vertical bar V-cs vertical bar = 1.08 +/- 0.16 along with a lower limit of vertical bar V-cs vertical bar > 0.71 at the 95% confidence level, assuming that the Wc production through c to s quark coupling is dominant.

Crystal-field-split d-d excitations are resolved in the high-resolution RIXS spectra. In particular, the splitting due to noncubic crystal fields, derived from the splitting of j(eff) = 3/2 states, is much smaller than the typical spin-orbit energy scale in iridates, validating the applicability of jeff physics in A(2)IrO(3). We also find excitonic enhancement of the particle-hole excitation gap around 0.4 eV, indicating that the nearest-neighbor Coulomb interaction could be large. These findings suggest that both Na2IrO3 and Li2IrO3 can be described as spin-orbit Mott insulators, similar to the square lattice iridate Sr2IrO4.

The crystalline-to-amorphous phase transition pressure increases monotonically with Li concentration (from similar to 17.5 GPa for delithiated to no phase transition for fully lithiated cubic titania up to 60 GPa). The associated enhancement in structural stability is postulated to arise from a vacancy filling mechanism in which an applied pressure drives interstitial Li ions to vacancy sites in the oxide interior. The results are of significance for understanding mechanisms of structural response of metal oxide electrode materials at high pressures as well as emerging energy storage technologies utilizing such materials.

TI The non-random walk of chiral magnetic charge carriers in artificial spin ice SO SCIENTIFIC REPORTS LA English DT Article ID DOMAIN-WALLS; ENTROPY AB The flow of magnetic charge carriers (dubbed magnetic monopoles) through frustrated spin ice lattices, governed simply by Coulombic forces, represents a new direction in electromagnetism. Artificial spin ice nanoarrays realise this effect at room temperature, where the magnetic charge is carried by domain walls. Control of domain wall path is one important element of utilizing this new medium. By imaging the transit of domain walls across different connected 2D honeycomb structures we contribute an important aspect which will enable that control to be realized. Although apparently equivalent paths are presented to a domain wall as it approaches a Y-shaped vertex from a bar parallel to the field, we observe a stark non-random path distribution, which we attribute to the chirality of the magnetic charges. These observations are supported by detailed statistical modelling and micromagnetic simulations. The identification of chiral control to magnetic charge path selectivity invites analogy with spintronics. C1 [Zeissler, K.; Walton, S. K.; Cohen, L. F.; Branford, W.

We quantify three key physical and chemical principles, namely momentum-induced recoil during the decay event, defect creation due to physical displacement, and chemical evolution over time. A fourth effect, that of electronic excitation, is also discussed, but this is difficult to quantify and is strongly material dependent. The analysis is presented for the specific cases of SrTiO3 and SrH2. By comparing the recoil energy with available threshold displacement data we show that in many beta-decay situations defects such as Frenkel pairs will not be created during decay as the energy transfer is too low. This observation leads to the concept of chemical evolution over time, which we quantify using density functional theory. Using a combination of Bader analysis, phonon calculations and cohesive energy calculations, we show that beta decay leads to counter-intuitive behavior that has implications for nuclear waste storage and novel materials design.

TI Charge localization on the hexa-interstitial cluster in MgO SO JOURNAL OF PHYSICS-CONDENSED MATTER LA English DT Article ID AUGMENTED-WAVE METHOD; CERAMICS; COLLISION; RADIATION; OXIDES AB Density functional theory was used to study the effects of charge localization on the structure and mobility of the highly mobile hexa-interstitial cluster in MgO. It was found that the relative stability of the configurations changed as charge was localized, with the higher energy intermediate configuration of the neutral cluster becoming the lowest energy configuration for the doubly charged cluster. The singly charged cluster was found to have the lowest migration barrier, with a barrier of 0.18 eV. The high mobility of the singly charged hexa-interstitial cluster could have a significant effect on microstructure evolution following radiation damage, while the detailed properties will be sensitive to the level of doping in the material.

The Lactobacillales order of bacteria collates various microorganisms having a large economic impact, including both human and animal pathogens and strains used in the food industry. Nonetheless, no systematic genome-wide analysis of transcriptional regulation has been previously made for this taxonomic group. Results: A comparative genomics approach was used for reconstruction of transcriptional regulatory networks in 30 selected genomes of lactic acid bacteria. The inferred networks comprise regulons for 102 orthologous transcription factors (TFs), including 47 novel regulons for previously uncharacterized TFs. Numerous differences between regulatory networks of the Streptococcaceae and Lactobacillaceae groups were described on several levels. The two groups are characterized by substantially different sets of TFs encoded in their genomes. Content of the inferred regulons and structure of their cognate TF binding motifs differ for many orthologous TFs between the two groups. Multiple cases of non-orthologous displacements of TFs that control specific metabolic pathways were reported. Conclusions: The reconstructed regulatory networks substantially expand the existing knowledge of transcriptional regulation in lactic acid bacteria. In each of 30 studied genomes the obtained regulatory network contains on average 36 TFs and 250 target genes that are mostly involved in carbohydrate metabolism, stress response, metal homeostasis and amino acids biosynthesis. The inferred networks can be used for genetic experiments, functional annotations of genes, metabolic reconstruction and evolutionary analysis. All reconstructed regulons are captured within the Streptococcaceae and Lactobacillaceae collections in the RegPrecise database (http://regprecise.lbl.gov).

TI Microreactor Chemical Bath Deposition of Laterally Graded Cd1-xZnxS Thin Films: A Route to High-Throughput Optimization for Photovoltaic Buffer Layers SO CHEMISTRY OF MATERIALS LA English DT Article DE CdZnS; chemical bath deposition; microreactor; photovoltaic; cadmium zinc sulfide; zinc oxysulfide ID OPTICAL-PROPERTIES; SOLAR-CELLS; CDS; CADMIUM; ZNS; SPECTROSCOPY; CDXZN1-XS; ZNXCD1-XS; THIOUREA; GROWTH AB Cd1-xZnxS (CdZnS) is a promising replacement for the CdS buffer layers in copper indium gallium (dOselenide (CIGS) solar cells because the wider band gap of CdZnS offers improved optical transmittance of blue light. Chemical bath deposition (CBD) is the state-of-the-art deposition method for CdS and CdZnS. However, CBD of CdZnS is poorly understood, and relationships between bath composition and stoichiometry, microstructure, and optoelectronic properties of the deposited film are lacking. We introduce CBD using a continuous flow microreactor as a new technique to rapidly explore a wide variety of deposition conditions on a single substrate using spatially dependent characterization. X-ray diffraction and X-ray absorption spectroscopy indicate that the film is a mixture of nanocrystalline CdZnS and amorphous Zn(O,OH,S). Over the length of a single substrate, films showed increasing Zn:Cd ratio in the nanocrystalline phase, increasing amorphous content, and increasing quantum confinement, and resultant monotonic increase in band gap from 2.42 to 2.75 eV. Microreactor CBD (mu R-CBD) enables rapid identification of CdZnS compositions that are ideal candidates for thin film photovoltaics, as well as determination of the CBD conditions required to deposit them.

TI Interfaces and Composition Profiles in Metal-Sulfide Nanolayers Synthesized by Atomic Layer Deposition SO CHEMISTRY OF MATERIALS LA English DT Article DE chemical vapor deposition; metal sulfide; kesterite; nanostructure; mesoscopic; secondary ion mass spectrometry; SARISA; gentle dual beam; low-energy sputtering; high-resolution depth profile ID SENSITIZED SOLAR-CELLS; FILMS; DIFFUSION; ZNS; CU2ZNSNS4; CU AB The sharpness of interfaces in multilayer metal-sulfide thin films synthesized by atomic layer deposition (ALD) is virtually unexplored. Presented here are some first results that indicate metal-sulfide multilayer thin films deposited by ALD are in an entirely different regime than metal-oxides in terms of their composition profile. We propose a mixing number to characterize interfacial sharpness. The mixing number is the diffusion distance of mobile atomic species during layer deposition divided by the layer thickness in which the mobile species is diffusing. Ultrathin metal-sulfide multilayers with the structure ZnS/SnS2/Cu2S/Si substrate were synthesized by ALD because of the relevance of these binaries for formation of the photovoltaic alloy Cu2ZnSnS4 (CZTS). The composition profiles were measured by time-of-flight secondary-ion mass spectrometry (TOP SIMS) with high depth resolution, both as deposited and after annealing at different temperatures in argon. Diffuse interfaces between layers containing the intended elemental species were found in the as-deposited case, indicating a mixing number similar to unity at the synthesis temperature of 135 degrees C for several pairs of adjacent layers. Annealing the metal-sulfide multilayer structure at 425 degrees C for 60 min was sufficient to fully mix the layers. Composition profiles were also measured for 20 nm ZnO and 22 nm ZnS capping layers on annealed CZTS films. ZnO suppresses diffusion relative to ZnS but does not prevent it completely. This indicates that the real-time mobility of atomic species in the substrate or underlying layer, as synthesis takes place, plays a critical role in determining the composition profile of ALD multilayer films.

We exploit this approach to provide direct correlation between structural changes and the evolution of gas that occurs during the thermal decomposition of (over)charged cathode materials used in lithium-ion batteries. Results from charged LixNi0.8Co0.15Al0.05O2 cathode materials indicate that the, evolution of both O-2 and CO2 gases are strongly related to phase transitions that occur during thermal decomposition, specifically from the layered structure (space group R (3) over barm) to the disordered spinel structure (Fd (3) over barm), and finally to the rock-salt structure (Fm (3) over barm). The state of charge also significantly affects both the structural changes and the evolution of oxygen as the temperature increases: the more extensive the charge, the lower the temperature of the phase transitions and the larger the oxygen release. Ex situ X-ray absorption spectroscopy (XAS) and in situ transmission electron microscopy (TEM) are also utilized to investigate the local structural and valence state changes in Ni and Co ions, and to characterize microscopic morphology changes. The combination of these advanced tools provides a unique approach to study fundamental aspects of the dynamic physical and chemical changes that occur during thermal decomposition of charged cathode materials in a systematic way.

Here, we describe a novel approach to the synthesis of SrTiO3 nanoparticles of different shapes from a microemulsion. We show that the microemulsion structure plays a critical role in the shape of the nanoparticles, with diffusion-limited growth when normal or reverse micelles are present to nanocuboids with a kinetic-Wulff shape in a lamellar microemulsion leading to nanocuboids. As determined by a combination of in situ small-angle Xray scattering (SAXS) and wide-angle X-ray scattering (WAXS) as a function of temperature and ex situ high-angle annular dark field (HAADF) imaging, the as-prepared SrTiO3 nanocuboids grow between three layers of water (3 x 1.1 nm) and two layers of oil (2 X 2.3 nm) leading to individual crystals which are uniformly 8 nm thick with somewhat greater lengths and widths.

In particular, this pH/charge effect provides a means of synthetic control over the properties and morphologies of ionic solids formed from cationic and anionic porphyrins. In the case of titration of an axial hydroxide ligand of the metal of the porphyrin to water, the charge increases by +1 with little perturbation of the molecular structure of the constituent porphyrin anion or cation. The structure of the material is thus altered without significantly altering the electronic structure of the porphyrin tecton. These novel porphyrin-based ionic materials have potential applications as catalysts, photocatalysts, and optoelectronic and sensing materials.

Among the tested monomers, only styrene derivatives could be directly grafted onto copper-supported graphene. Therefore, copolymerization of styrene and acrylates, as well as consecutive grafting of both monomer types, was employed to realize functional polymer brushes of poly(styrene-co-acrylate) copolymers. The direct grafting of polymers on graphene results in polymer carpets that are suitable for a wide variety of applications. C1 [Seifert, Max; Koch, Amelie H.

TI Electrochemical and Solid-State Lithiation of Graphitic C3N4 SO CHEMISTRY OF MATERIALS LA English DT Article DE carbon nitride; lithiation; anode; battery ID LITHIUM-ION BATTERIES; DOPED GRAPHENE NANOSHEETS; SUR LE GRAPHITE; CARBON NITRIDE; ANODE MATERIALS; HARD CARBON; LA VAPEUR; NITROGEN; STORAGE; PERFORMANCE AB Lithiated graphitic carbon nitride (C3N4) was fabricated by electrochemical and solid-state reactions. The addition of Li to C3N4 results in a reaction between the Li and the graphite-like C3N species in C3N4. This irreversible reaction leads to the formation of Li-CH=NR and Li-N=CR2 species, which are detrimental to anode properties. Suitable nitrogen-doped carbon structures for anode applications are predicted to need high concentrations of pyridinic C-N-C terminal bonds and low concentrations of quaternary C3N species to boost electronic conductivity and reversibly cycle Li ions.

TI Improving Microbial Genome Annotations in an Integrated Database Context SO PLOS ONE LA English DT Article ID METABOLIC PATHWAYS; SYSTEM; TOOLS AB Effective comparative analysis of microbial genomes requires a consistent and complete view of biological data. Consistency regards the biological coherence of annotations, while completeness regards the extent and coverage of functional characterization for genomes. We have developed tools that allow scientists to assess and improve the consistency and completeness of microbial genome annotations in the context of the Integrated Microbial Genomes (IMG) family of systems. All publicly available microbial genomes are characterized in IMG using different functional annotation and pathway resources, thus providing a comprehensive framework for identifying and resolving annotation discrepancies. A rule based system for predicting phenotypes in IMG provides a powerful mechanism for validating functional annotations, whereby the phenotypic traits of an organism are inferred based on the presence of certain metabolic reactions and pathways and compared to experimentally observed phenotypes. The IMG family of systems are available at http://img.jgi.doe.gov/.

TI An attenuated Lassa vaccine in SIV-infected rhesus macaques does not persist or cause arenavirus disease but does elicit Lassa virus-specific immunity SO VIROLOGY JOURNAL LA English DT Article DE Lassa fever virus; Vaccine; Macaque; SIV-infected; Genomic profiling; Disease markers ID SIMIAN IMMUNODEFICIENCY VIRUS; LYMPHOCYTIC CHORIOMENINGITIS VIRUS; HEMORRHAGIC-FEVER; LIVER PATHOLOGY; GENE-EXPRESSION; MOPEIA VIRUSES; T-CELLS; RESPONSES; MONKEYS; ANTIBODY AB Background: Lassa hemorrhagic fever (LHF) is a rodent-borne viral disease that can be fatal for human beings. In this study, an attenuated Lassa vaccine candidate, ML29, was tested in SIV-infected rhesus macaques for its ability to elicit immune responses without instigating signs pathognomonic for arenavirus disease. ML29 is a reassortant between Lassa and Mopeia viruses that causes a transient infection in non-human primates and confers sterilizing protection from lethal Lassa viral challenge. However, since the LHF endemic area of West Africa also has high HIV seroprevalence, it is important to determine whether vaccination could be safe in the context of HIV infection. Results: SIV-infected and uninfected rhesus macaques were vaccinated with the ML29 virus and monitored for specific humoral and cellular immune responses, as well as for classical and non-classical signs of arenavirus disease. Classical disease signs included viremia, rash, respiratory distress, malaise, high liver enzyme levels, and virus invasion of the central nervous system. Non-classical signs, derived from profiling the blood transcriptome of virulent and non-virulent arenavirus infections, included increased expression of interferon-stimulated genes (ISG) and decreased expression of COX2, IL-1 beta, coagulation intermediates and nuclear receptors needed for stress signaling. All vaccinated monkeys showed ML29-specific antibody responses and ML29-specific cell-mediated immunity. Conclusion: SIV-infected and uninfected rhesus macaques responded similarly to ML29 vaccination, and none developed chronic arenavirus infection. Importantly, none of the macaques developed signs, classical or non-classical, of arenavirus disease.

TI MultiAlign: a multiple LC-MS analysis tool for targeted omics analysis SO BMC BIOINFORMATICS LA English DT Article DE Metabolomics; Proteomics; Mass spectrometry; Liquid chromatography; Spectral clustering; Alignment ID CHROMATOGRAPHY-MASS SPECTROMETRY; ACCURATE MASS; PEPTIDE IDENTIFICATION; SPECTRA; TANDEM; PROTEOMICS; ALGORITHM; ALIGNMENT; SYSTEM AB Background: MultiAlign is a free software tool that aligns multiple liquid chromatography-mass spectrometry datasets to one another by clustering mass and chromatographic elution features across datasets. Applicable to both label-free proteomics and metabolomics comparative analyses, the software can be operated in several modes. For example, clustered features can be matched to a reference database to identify analytes, used to generate abundance profiles, linked to tandem mass spectra based on parent precursor masses, and culled for targeted liquid chromatography-tandem mass spectrometric analysis. MultiAlign is also capable of tandem mass spectral clustering to describe proteome structure and find similarity in subsequent sample runs. Results: MultiAlign was applied to two large proteomics datasets obtained from liquid chromatography-mass spectrometry analyses of environmental samples. Peptides in the datasets for a microbial community that had a known metagenome were identified by matching mass and elution time features to those in an established reference peptide database. Results compared favorably with those obtained using existing tools such as VIPER, but with the added benefit of being able to trace clusters of peptides across conditions to existing tandem mass spectra. MultiAlign was further applied to detect clusters across experimental samples derived from a reactor biomass community for which no metagenome was available. Several clusters were culled for further analysis to explore changes in the community structure. Lastly, MultiAlign was applied to liquid chromatography-mass spectrometry-based datasets obtained from a previously published study of wild type and mitochondrial fatty acid oxidation enzyme knockdown mutants of human hepatocarcinoma to demonstrate its utility for analyzing metabolomics datasets. Conclusion: MultiAlign is an efficient software package for finding similar analytes across multiple liquid chromatography-mass spectrometry feature maps, as demonstrated here for both proteomics and metabolomics experiments. The software is particularly useful for proteomic studies where little or no genomic context is known, such as with environmental proteomics.

Deep sequencing has the potential to reveal the mutant spectrum within a viral sample at high resolution, thus enabling the close examination of viral mutational dynamics both within- and between-hosts. The challenge however, is to accurately model the errors in the sequencing data and differentiate real viral mutations, particularly those that exist at low frequencies, from sequencing errors. Results: We demonstrate that overlapping read pairs (ORP) - generated by combining short fragment sequencing libraries and longer sequencing reads - significantly reduce sequencing error rates and improve rare variant detection accuracy. Using this sequencing protocol and an error model optimized for variant detection, we are able to capture a large number of genetic mutations present within a viral population at ultra-low frequency levels (<0.05%). Conclusions: Our rare variant detection strategies have important implications beyond viral evolution and can be applied to any basic and clinical research area that requires the identification of rare mutations.

The calixarene acts as a molecular template that enforces open and closed resting-state coordination geometries surrounding the metal active sites, due to its lower-rim substituents as well as site isolation by virtue of its steric bulk. These sites are characterized and used to elucidate mechanistic details and connectivity requirements for reactions involving hydride and oxo transfer. The consequence of controlling open versus closed configurations of the grafted Lewis acid site is demonstrated by the complete lack of observed activity of the closed site for Meerwein-Ponndorf-Verley (MPV) reduction; whereas, the open variant of this catalyst has an MPV reduction activity that is virtually identical to previously reported soluble molecular Al(III)-calix[4] arene catalysts. In contrast, for olefin epoxidation using tert-butyl-hydroperoxide as oxidant, the open and closed catalysts exhibit similar activity. This observation suggests that for olefin epoxidation catalysis using Lewis acids as catalyst and organic hydroperoxide as oxidant, covalent binding of the hydroperoxide is not required, and instead dative coordination to the Lewis acid center is sufficient for catalytic oxo transfer. This latter result is supported by density functional theory calculations of the transition state for olefin epoxidation catalysis, using molecular analogs of the open and closed catalysts.

TI Morphologies of ABC Triblock Terpolymer Melts Containing Poly(Cyclohexadiene): Effects of Conformational Asymmetry SO LANGMUIR LA English DT Article ID BLOCK-COPOLYMER MELTS; LIVING ANIONIC-POLYMERIZATION; CONSISTENT-FIELD THEORY; DIBLOCK COPOLYMERS; PHASE-BEHAVIOR; NETWORK PHASES; N-BUTYLLITHIUM/N,N,N',N'-TETRAMETHYLETHYLENEDIAMINE SYSTEM; 1,3-CYCLOHEXADIENE POLYMERS; MICROPHASE SEPARATION; MULTIPHASE MORPHOLOGY AB We have synthesized linear ABC triblock terpolymers containing poly(1,3-cyclohexadiene), PCHD, as an end block and characterized their morphologies in the melt. Specifically, we have studied terpolymers containing polystyrene (PS), polybutadiene (PB), and polyisoprene (PI) as the other blocks. Systematically varying the ratio of 1,2- /1,4-microstructures of poly(1,3-cyclohexadiene), we have studied the effects of conformational asymmetry among the three blocks on the morphologies using transmission electron microscopy (TEM), small-angle X-ray scattering (SAXS), and self-consistent field theory (SCFT) performed with PolySwift++. Our work reveals that the triblock terpolymer melts containing a high percentage of 1,2-microstructures in the PCHD block are disordered at 110 degrees C for all the samples, independent of sequence and volume fraction of the blocks. In contrast, the triblock terpolymer melts containing a high percentage of 1,4-microstructure form regular morphologies known from the literature. The accuracy of the SCFT calculations depends on calculating the chi parameters that quantify the repulsive interactions between different monomers. Simulations using chi values obtained from solubility parameters and group contribution methods are unable to reproduce the morphologies as seen in the experiments. However, SCFT calculations accounting for the enhancement of the chi parameter with an increase in the conformational asymmetry lead to an excellent agreement between theory and experiments. These results highlight the importance of conformational asymmetry in tuning the chi parameter and, in turn, morphologies in block copolymers.

CA ALICE Collaboration TI Anisotropic flow of charged hadrons, pions and (anti-)protons measured at high transverse momentum in Pb-Pb collisions at root S-NN=2.76 TeV SO PHYSICS LETTERS B LA English DT Article ID RELATIVISTIC NUCLEAR COLLISIONS; ELLIPTIC FLOW; LHC; ALICE; PP AB The elliptic, v(2), triangular, v(3), and quadrangular, v(4), azimuthal anisotropic flow coefficients are measured for unidentified charged particles, pions, and (anti-)protons in Pb-Pb collisions at root S-NN = 2.76 TeV with the ALICE detector at the Large Hadron Collider. Results obtained with the event plane and four-particle cumulant methods are reported for the pseudo-rapidity range vertical bar eta vertical bar < 0.8 at different collision centralities and as a function of transverse momentum, p(T), out to p(T) = 20 GeV/c. The observed non-zero elliptic and triangular flow depends only weakly on transverse momentum for p(T) > 8 GeV/c. The small p(T) dependence of the difference between elliptic flow results obtained from the event plane and four-particle cumulant methods suggests a common origin of flow fluctuations up to p(T) = 8 GeV/c. The magnitude of the (anti-)proton elliptic and triangular flow is larger than that of pions out to at least p(T) = 8 GeV/c indicating that the particle type dependence persists out to high p(T).

The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity, and expressed as associated yield per trigger particle. Two long-range ridge-like structures, one on the near side and one on the away side, are observed when the per-trigger yield obtained in low-multiplicity events is subtracted from the one in high-multiplicity events. The excess on the near-side is qualitatively similar to that recently reported by the CMS Collaboration, while the excess on the away-side is reported for the first time. The two-ridge structure projected onto azimuthal angle is quantified with the second and third Fourier coefficients as well as by near-side and away-side yields and widths. The yields on the near side and on the away side are equal within the uncertainties for all studied event multiplicity and p(T) bins, and the widths show no significant evolution with event multiplicity or p(T). These findings suggest that the near-side ridge is accompanied by an essentially identical away-side ridge. (c) 2013 CERN. Published by Elsevier B.V. All rights reserved.

CA CMS Collaboration TI Search for supersymmetry in events with photons and low missing transverse energy in pp collisions at root s=7 TeV SO PHYSICS LETTERS B LA English DT Article DE CMS; Physics ID BREAKING; SQUARK AB Many models of new physics, including versions of supersymmetry (SUSY), predict production of events with low missing transverse energy, electroweak gauge bosons, and many energetic final-state particles. The stealth SUSY model yields this signature while conserving R-parity by means of a new hidden sector in which SUSY is approximately conserved. The results of a general search for new physics, with no requirement on missing transverse energy, in events with two photons and four or more hadronic jets are reported. The study is based on a sample of proton-proton collisions at root s = 7 TeV corresponding to 4.96 fb(-1) of integrated luminosity collected with the CMS detector in 2011. Based on good agreement between the data and the standard model expectation, the data are used to determine model-independent cross-section limits and a limit on the squark mass in the framework of stealth SUSY. With this first study of its kind, squark masses less than 1430 GeV are excluded at the 95% confidence level. (c) 2012 CERN. Published by Elsevier B.V. All rights reserved.

CA STAR Collaboration TI Single spin asymmetry AN in polarized proton-proton elastic scattering at root s=200 GeV SO PHYSICS LETTERS B LA English DT Article DE Polarization; Elastic scattering ID 1ST MEASUREMENT; IMPACT-PICTURE; PP; INTERFERENCE; POMERON; REGION; ENERGY; BEAM; A(N) AB We report a high precision measurement of the transverse single spin asymmetry A(N) at the center of mass energy root s = 200 GeV in elastic proton-proton scattering by the STAR experiment at RHIC. The A(N) was measured in the four-momentum transfer squared t range 0.003 <= vertical bar t vertical bar <= 0.035 (GeV/c)(2), the region of a significant interference between the electromagnetic and hadronic scattering amplitudes. The measured values of A(N) and its t-dependence are consistent with a vanishing hadronic spin-flip amplitude, thus providing strong constraints on the ratio of the single spin-flip to the non-flip amplitudes. Since the hadronic amplitude is dominated by the Pomeron amplitude at this root s, we conclude that this measurement addresses the question about the presence of a hadronic spin flip due to the Pomeron exchange in polarized proton-proton elastic scattering.

TI First determination of an astrophysical cross section with a bubble chamber: The N-15(alpha, gamma)F-19 re-action SO PHYSICS LETTERS B LA English DT Article ID DARK-MATTER; SEARCH AB We have devised a technique for measuring some of the most important nuclear reactions in stars which we expect to provide considerable improvement over previous experiments. Adapting ideas from dark matter search experiments with bubble chambers, we have found that a superheated liquid is sensitive to recoils produced from gamma rays photodisintegrating the nuclei of the liquid. The main advantage of the new target-detector system is a gain in yield of six orders of magnitude over conventional gas targets due to the higher mass density of liquids. Also, the detector is practically insensitive to the gamma-ray beam itself, thus allowing it to detect only the products of the nuclear reaction of interest. The first set of tests of a superheated target with a narrow bandwidth gamma-ray beam was completed and the results demonstrate the feasibility of the scheme. The new data are successfully described by an R-matrix model using published resonance parameters. With the increase in luminosity of the next generation gamma-ray beam facilities, the measurement of thermonuclear rates in the stellar Gamow window would become possible. (c) 2013 Elsevier B.V.

TI Self-Assembly and Transport Limitations in Confined Nafion Films SO MACROMOLECULES LA English DT Article ID COPOLYMER THIN-FILMS; ELECTROLYTE FUEL-CELLS; ANGLE X-RAY; WATER-UPTAKE; PROTON CONDUCTIVITY; IONOMER SOLUTIONS; CATALYST LAYERS; MEMBRANES; VAPOR; SPECTROSCOPY AB Ion-conducting polymers are important materials for a variety of electrochemical applications. Perfluorinated ionomers, such as Nafion, are the benchmark materials for proton conduction and are widely used in fuel cells and other electrochemical devices including solar-fuel generators, chlor-alkali cells, and redox flow batteries. While the behavior of Nafion in bulk membranes (10 to 100s mu m thick) has been studied extensively, understanding its properties under thin-film confinement is limited. Elucidating the behavior of thin Nafion films is particularly important for the optimization of fuel-cell catalyst layers or vapor-operated solar-fuel generators, where a thin film of ionomer is responsible for the transport of ions to and from the active electrocatalytic centers. Using a combination of transport-property measurements and structural characterization, this work demonstrates that confinement of Nafion in thin films induced thickness-dependent proton conductivity and ionic-domain structure. Confining Nafion films to thicknesses below 50 nm on a silicon substrate results in a loss of microphase separation of the hydrophilic and hydrophobic domains, which drastically increases the material's water uptake while in turn decreasing its ionic conductivity.

TI Ionic Conductivity of Low Molecular Weight Block Copolymer Electrolytes SO MACROMOLECULES LA English DT Article ID RECHARGEABLE LITHIUM BATTERIES; POLYMER ELECTROLYTES; ORDER-DISORDER; TRANSITIONS; TRANSPORT AB The ionic conductivity and glass transition temperatures of nanostructured block copolymer electrolytes composed of polystyrene-b-poly(ethylene oxide) (SEO) doped with lithium bis(trifluoromethanesulfone)imide (LiTFSI) were studied in the small molecular weight limit (between 2.7 and 13.7 kg mol(-1)). In this range, the annealed conductivity exhibits a nonmonotonic dependence on molecular weight, decreasing with increasing molecular weight in the small molecular weight limit before increasing when molecular weight exceeds about 10 kg mol(-1). We show that annealed electrolyte conductivity is affected by two competing factors: the glass transition temperature of the insulating polystyrene (PS) block and the width of the conducting poly(ethylene oxide) (PEO) channel. In the low molecular weight limit, all ions are in contact with both PS and PEO segments. The intermixing between PS and PEO segments is restricted to an interfacial zone of width, lambda. Our experiments suggest that lambda is about 5 nm. The fraction of ions affected by the interfacial zone decreases as the conducting channel width increases. We also study the effect of thermal history on the conductivity of the block copolymer electrolytes. Our data suggest that long-range order impedes ion transport.

Yu, Chiu-Tien TI Stops and is not an element of(T): The shape of things to come SO PHYSICAL REVIEW D LA English DT Article ID PROTON-PROTON COLLISIONS; SCALAR TOP-QUARK; MISSING TRANSVERSE-MOMENTUM; ROOT-S=7 TEV; QCD CORRECTIONS; PAIR PRODUCTION; ATLAS DETECTOR; FINAL-STATES; SUSY-QCD; SEARCH AB LHC experiments have placed strong bounds on the production of supersymmetric colored particles (squarks and gluinos), under the assumption that all flavors of squarks are nearly degenerate. However, the current experimental constraints on stop squarks are much weaker, due to the smaller production cross section and difficult backgrounds. While light stops are motivated by naturalness arguments, it has been suggested that such particles become nearly impossible to detect near the limit where their mass is degenerate with the sum of the masses of their decay products. We show that this is not the case, and that searches based on missing transverse energy (is not an element of(T)) have significant reach for stop masses above 175 GeV, even in the degenerate limit. We consider direct pair production of stops, decaying to invisible lightest supersymmetric particles (LSPs) and tops with either hadronic or semileptonic final states. Modest intrinsic differences in is not an element of(T) are magnified by boosted kinematics and by shape analyses of is not an element of(T) or suitably chosen observables related to is not an element of(T). For these observables we show that the distributions of the relevant backgrounds and signals are well described by simple analytic functions, in the kinematic regime where signal is enhanced. Shape analyses of is not an element of(T)-related distributions will allow the LHC experiments to place significantly improved bounds on stop squarks, even in scenarios where the stop-LSP mass difference is degenerate with the top mass. Assuming 20 fb(-1) of luminosity at root s = 8 TeV, we conservatively estimate that experiments can exclude or discover degenerate stops with masses as large as similar to 360 GeV, and 560 GeV for massless LSPs.

Edwards, Robert G. Thomas, Christopher E. TI Energy dependence of the rho resonance in pi pi elastic scattering from lattice QCD SO PHYSICAL REVIEW D LA English DT Article ID FINITE-VOLUME AB We determine the energy-dependent amplitude for elastic pi pi P-wave scattering in isospin-1 by computing part of the discrete energy spectrum of QCD in finite cubic boxes. We observe a rapidly rising phase shift that can be well described by a single rho resonance. The spectrum is obtained from hadron correlators computed using lattice QCD with light quark masses corresponding to m(pi) similar to 400 MeV. Variational analyses are performed with large bases of hadron interpolating fields including, as well as fermion bilinears that resemble q (q) over bar constructions, also operators that resemble pairs of pions with definite relative and total momentum. We compute the spectrum for a range of center-of-mass momenta and in various irreducible representations of the relevant symmetry group. Hence we determine more than 30 values of the isospin-1 P-wave scattering phase shift in the elastic region, mapping out its energy dependence in unprecedented detail.

CA Belle Collaboration TI Precise measurement of the branching fractions for B-s(0) -> D-s(()*()+) D-s(()*()-) and first measurement of the D-s*(+) D-s*(-) polarization using e(+)e(-) collisions SO PHYSICAL REVIEW D LA English DT Article ID DECAYS AB We have made a precise measurement of the absolute branching fractions of B-s(0) -> D-s(()*()+) D-s(()*()-) decays using 121.4 fb(-1) of data recorded by the Belle experiment running at the Upsilon(5S) resonance. The results are B(B-s(0) -> D-s(+) D-s(-)) = 0.58(-0.09)(+0.11) +/- 0.13)%, B(B-s(0) -> D-s*(+/-) D-s(-/+)) = (1.76(-0.22)(+0.23) +/- 0.40)%, and B(B-s(0) -> D-s*(+) D-s*(-)) = (1.98(-0.31-0.50)(+0.33+0.52))%; the sum is B(B-s(0) -> D-s(()*()+) D-s(()*()-)) = (4.32(-0.39-1.03)(+0.42+1.04))%. Assuming B-s(0) -> D-s(()*()+) D-s(()*()-) saturates decays to CP-even final states, the branching fraction constrains the ratio Delta Gamma(s)/cos phi(12), where Delta Gamma(s) is the difference in widths between the two B-s-(B) over bar (s) mass eigenstates, and phi(12) is the CP-violating phase in B-s-(B) over bar (s) mixing. We also measure for the first time the longitudinal polarization fraction of B-s(0) -> D-s*(+) D-s*(-); the result is 0.06(-0.17)(+0.18) +/- 0.03.

CA BaBbar Collaboration TI Branching fraction measurement of B+ -> omega l(+)nu decays SO PHYSICAL REVIEW D LA English DT Article ID MONTE-CARLO; HEAVY AB We present a measurement of the B+ -> omega l(+)nu branching fraction based on a sample of 467 million B (B) over bar pairs recorded by the BABAR detector at the SLAC PEP-II e(+)e(-) collider. We observe 1125 +/- 131 signal decays, corresponding to a branching fraction of B(B+ -> omega l(+)nu) = (1.21 +/- 0.14 +/- 0.08) x 10(-4), where the first error is statistical and the second is systematic. The dependence of the decay rate on q(2), the invariant mass squared of the leptons, is compared to QCD predictions of the form factors based on a quark model and light-cone sum rules.

The factor of 16 arises from a four-fold quantum enhancement through the use of an N = 4 N00N state and a four-fold classical enhancement from a quadruple pass through a prism pair. The possibility of achieving supersensitivity using this method is discussed. (C) 2013 Optical Society of America C1 [Shin, Heedeuk] Sandia Natl Labs, Albuquerque, NM 87123 USA.

We analytically prove that the condition of MPA requires the existence of two currents, which are nearly out of phase and have almost identical amplitude, akin to a magnetic dipole. Furthermore, we show that non-zero-order Bragg modes within the MPA may consume electromagnetic energy significantly. (C) 2013 Optical Society of America C1 [Zeng, Yong; Dalvit, Diego A.

PbTe1-x Sx thermoelectric materials can be synthesized as metastable solid solution alloys through rapid quenching. Subsequent post-annealing induces phase separation at the nanometer scale, producing nanostructures that increase phonon scattering and reduce lattice thermal conductivity. However, there has yet to be any study investigating in detail the local chemical structure of both the solid solution and nanostructured variants of this material system. Herein, quenched and annealed (i.e., solid solution and phase-separated) samples of PbTePbS are analyzed by in situ high-resolution synchrotron powder X-ray diffraction, solid-state 125Te nuclear magnetic resonance (NMR), and infrared (IR) spectroscopy analysis. For high concentrations of PbS in PbTe, e.g., x >16%, NMR and IR analyses reveal that rapidly quenched samples exhibit incipient phase separation that is not detected by state-of-the-art synchrotron X-ray diffraction, providing an example of a PbTe thermoelectric alloy that is in fact phase inhomogeneous. Thermally-induced PbS phase separation in PbTePbS occurs close to 200 degrees C for all compositions studied, and the solubility of the PbS phase in PbTe at elevated temperatures >500 degrees C is reported. The findings of this study suggest that there may be a large number of thermoelectric alloy systems that are phase inhomogeneous or nanostructured despite adherence to Vegard's Law of alloys, highlighting the importance of careful chemical characterization to differentiate between thermoelectric alloys and composites.

TI Influence of a Dy overlayer on the precessional dynamics of a ferromagnetic thin film SO APPLIED PHYSICS LETTERS LA English DT Article ID MAGNETIC-CIRCULAR-DICHROISM; RAY; DOPANTS AB Precessional dynamics of a Co50Fe50(0.7)/Ni90Fe10(5)/Dy(1)/Ru(3) (thicknesses in nm) thin film have been explored by low temperature time-resolved magneto-optical Kerr effect and phase-resolved x-ray ferromagnetic resonance measurements. As the temperature was decreased from 300 to 140 K, the magnetic damping was found to increase rapidly while the resonance field was strongly reduced. Static x-ray magnetic circular dichroism measurements revealed increasing ferromagnetic order of the Dy moment antiparallel to that of Co50Fe50/Ni90Fe10. Increased coupling of the Dy orbital moment to the precessing spin magnetization leads to significantly increased damping and gyromagnetic ratio of the film while leaving its magnetic anisotropy effectively unchanged.

The intrinsic contribution depended weakly on bias field and frequency, while the extrinsic contribution strongly depended on these same parameters as well as temperature. The threshold bias field required to suppress domain wall motion in PLZT thin films was similar to 20-25 MV/m, and the intrinsic permittivity measured at those fields was similar to 300-350, in agreement with literature values.

We discuss superbeams, beta beams, and neutrino factories, and for the first time compare these experiments on an equal footing with respect to systematic errors. We explicitly simulate near detectors for all experiments; we use the same implementation of systematic uncertainties for all experiments; and we fully correlate the uncertainties among detectors, oscillation channels, and beam polarizations as appropriate. As our primary performance indicator, we use the achievable precision in the measurement of the CP-violating phase delta. We find that a neutrino factory is the only instrument that can measure delta with a precision similar to that of its quark sector counterpart. All neutrino beams operating at peak energies >= 2 GeV are quite robust with respect to systematic uncertainties, whereas especially beta beams and T2HK suffer from large cross-section uncertainties in the quasielastic regime, combined with their inability to measure the appearance signal cross sections at the near detector. A noteworthy exception is the combination of a gamma = 100 beta beam with an SPL-based superbeam, in which all relevant cross sections can be measured in a self-consistent way. This provides a performance second only to that of the neutrino factory. For other superbeam experiments such as LBNO and the setups studied in the context of the LBNE reconfiguration effort, statistics turns out to be the bottleneck. In almost all cases, the near detector is not critical to control systematics, since the combined fit of appearance and disappearance data already constrains the impact of systematics to be small, provided that the three-active-flavor oscillation framework is valid.

In particular, LaVO3 grown on SrTiO3 has a direct band gap similar to 1.1 eV in the optimal range as well as an internal potential gradient, which can greatly help to separate the photo-generated electron-hole pairs. Furthermore, oxide heterostructures afford the flexibility to combine LaVO3 with other materials such as LaFeO3 in order to achieve even higher efficiencies with band-gap graded solar cells. We use density-functional theory to demonstrate these features.

TI Dipolar Order by Disorder in the Classical Heisenberg Antiferromagnet on the Kagome Lattice SO PHYSICAL REVIEW LETTERS LA English DT Article ID GROUND-STATE; SPIN-LIQUID; FRUSTRATION; MODEL AB Ever since the experiments which founded the field of highly frustrated magnetism, the kagome Heisenberg antiferromagnet has been the archetypical setting for the study of fluctuation induced exotic ordering. To this day the nature of its classical low-temperature state has remained a mystery: the nonlinear nature of the fluctuations around the exponentially numerous harmonically degenerate ground states has not permitted a controlled theory, while its complex energy landscape has precluded numerical simulations at low temperature, T. Here we present an efficient Monte Carlo algorithm which removes the latter obstacle. Our simulations detect a low-temperature regime in which correlations asymptote to a remarkably small value as T -> 0. Feeding these results into an effective model and analyzing the results in the framework of an appropriate field theory implies the presence of long-range dipolar spin order with a tripled unit cell.

This separation into "resonance" and "background" contributions of the cross section is artificial. We propose to explain this phenomenon through the impact on the cross section of the relatively large spacings and the narrow widths of Mg-24 compound levels in the corresponding excitation-energy region.

A nanohole array-based copper surface was designed to exhibit a plasmonic response at 800 nm, fabricated using the focused ion beam milling technique, optically characterized and tested as a photocathode in a high power radio frequency photoinjector. Because of the larger absorption and localization of the optical field intensity, the charge yield observed under ultrashort laser pulse illumination is increased by more than 100 times compared to a flat surface. We also present the first beam characterization results (intrinsic emittance and bunch length) from a nanostructured photocathode. DOI: 10.1103/PhysRevLett.110.074801 C1 [Li, R.

TI Plasmon-Enhanced Photocathode for High Brightness and High Repetition Rate X-Ray Sources SO PHYSICAL REVIEW LETTERS LA English DT Article ID ELECTRON; NANOSTRUCTURES; MICROSCOPY; METALS AB In this Letter, we report on the efficient generation of electrons from metals using multiphoton photoemission by use of nanostructured plasmonic surfaces to trap, localize, and enhance optical fields. The plasmonic surface increases absorption over normal metals by more than an order of magnitude, and due to the localization of fields, this results in over 6 orders of magnitude increase in effective nonlinear quantum yield. We demonstrate that the achieved quantum yield is high enough for use in rf photoinjectors operating as electron sources for MHz repetition rate x-ray free electron lasers.

TI Multiband Optical Absorption Controlled by Lattice Strain in Thin-Film LaCrO3 SO PHYSICAL REVIEW LETTERS LA English DT Article AB Experimental measurements and ab initio modeling of the optical transitions in strained G-type antiferromagnetic LaCrO3 resolve two decades of debate regarding the magnitude of the band gap and the character of the optical absorption spectrum in the visible-to-ultraviolet (up to similar to 5 eV) range in this material. Using time-dependent density functional theory and accounting for thermal disorder effects, we demonstrate that the four most prominent low-energy absorption features are due to intra-Cr t(2g)-e(g) (2.7, 3.6 eV), inter-Cr t(2g)-t(2g) (4.4 eV), and interion O 2p-Cr 3d (from similar to 5 eV) transitions and show that the excitation energies of the latter type can be strongly affected by the lattice strain.

The simple, linear, Dirac cone band structure offers a unique possibility to investigate its finer details by angle-resolved photoelectron spectroscopy (ARPES). Indeed, ARPES has been performed on graphene grown on metal substrates but electronic applications require an insulating substrate. Epitaxial graphene grown by the thermal decomposition of silicon carbide (SiC) is an ideal candidate for this due to the large scale, uniform, graphene layers produced. The experimental spectral function of epitaxial graphene on SiC has been extensively studied. However, until now the cause of an anisotropy in the spectral width of the Fermi surface has not been determined. In the current work we show, by comparison of the spectral function to a semi-empirical model, that the anisotropy is due to small scale rotational disorder (similar to +/- 0.15 degrees) of graphene domains in graphene grown on SiC(0001) samples. The complicated shape described by the line-width is accurately reproduced by the semi-empirical model only when rotational disorder is included. While spectra from rare regions of the sample containing only one or two rotational domains is also presented. In addition to the direct benefit in the understanding of graphene's electronic structure this work suggests a mechanism to explain similar variations in related ARPES data.

TI The development of a new, neutron, time correlated, interrogation method for measurement of U-235 content in LWR fuel assemblies SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Fresh fuel measurements; Neutron interrogation; Nuclear safeguards; Light water reactor fuel AB This paper presents the first application of a new technique for the measurement of the U-235 content in fresh fuel assemblies. The technique, called time correlated induced fission (TCIF), uses a Cf-252 neutron source to irradiate the fuel assembly, and the subsequent induced fission events in the fissile material are measured by multiplicity counting. The doubles and triples rates are enhanced by having the trigger events from both the Cf-252 source and the induced fission neutrons in the same time gate in the coincidence analysis. The average neutrons per fission (v) of the Cf-252 source is 3.76 and the induced fission v for U-235 is 2.44, so the combined v is similar to 5.2 with one neutron removed by the fission reaction. This high effective v significantly increases the multiplicity counting rates and reduces the statistical error. The background coincidence counts from the Cf-252 have been minimized by neutron shielding between the source and the detector. This method of active neutron interrogation has been applied to the measurement of fresh pressurized water reactor (PWR) fuel assemblies. The neutron uranium collar (UNCL) that is routinely used for U-235 verification in PWR reactor fuel assemblies is used to compare the TCIF method with the typically used AmLi neutron interrogation source. This paper presents both the experimental verification of the TCIF method for a PWR mockup assembly and the MCMPX simulations to optimize the detector geometry. Published by Elsevier B.V.

In this study, the FDIRC prototype has been instrumented with seven Hamamatsu H-8500 MaPMTs. Waveforms from 384 pixels are digitized with waveform sampling electronics based on the BLAB2 ASIC, operating at a sampling speed of similar to 2.5 GSa/s. The FDIRC prototype was tested in a large cosmic ray telescope (CRT) providing 3D muon tracks with similar to 1.5 mrad angular resolution and muon energy of E-muon > 1.6 GeV. In this study we provide a detailed analysis of the tails in the Cherenkov angle distribution as a function of various variables, compare experimental results with simulation, and identify the major contributions to the tails. We demonstrate that to see the full impact of these tails on the Cherenkov angle resolution, it is crucial to use 3D tracks, and have a full understanding of the role of reconstruction ambiguities. These issues could not be fully explored in previous FDIRC studies where the beam was perpendicular to the quartz radiator bars. This work is relevant for the final FDIRC prototype of the PID detector at SuperB, which will be tested this year in the CRT setup. Published by Elsevier B.V.

TI Characteristics of signals originating near the lithium-diffused N plus contact of high purity germanium p-type point contact detectors SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Germanium detectors; Dead layer; Transition layer ID NUCLEUS COHERENT SCATTERING; PULSE-SHAPE DISCRIMINATION; GAMMA-RAY SPECTROMETER; DARK-MATTER SEARCHES; DEAD-LAYER; SIMULATION; EFFICIENCY; TIME AB A study of signals originating near the lithium-diffused n+ contact of p-type point contact (PPC) high purity germanium detectors (HPGe) is presented. The transition region between the active germanium and the fully dead layer of the n+ contact is examined. Energy depositions in this transition region are shown to result in partial charge collection. This provides a mechanism for events with a well defined energy to contribute to the continuum of the energy spectrum at lower energies. A novel technique to quantify the contribution from this source of background is introduced. Experiments that operate germanium detectors with a very low energy threshold may benefit from the methods presented herein. Published by Elsevier B.V. C1 [Aguayo, E.; Fast, J. E.; Hoppe, E.

Part of the upgrade is the addition of a fast chopper in the LEBT (low energy beam transport) just before the RFQ. The novelty of this chopper is that it reflects rather than deflects beam. It also has low capacitance < 10 pF so that the rise and fall times of the beam pulse are dominated by cabling and the MOSFET switches. In fact, the measured rise and fall time of the chopped beam have been measured and they are better than 150 ns at 15 Hz. (C) 2012 Elsevier B.V. All rights reserved. C1 [Lackey, J. R.; Bollinger, D.

TI Monitoring system for a synthesizer at SPring-8 synchrotron radiation facility and obtained results SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Radio frequency; Synthesizer; Tidal forces; Energy correction; Atomic clock; SPring-8 ID ENERGY AB Beam orbit distortion in all dispersive sections was observed in the SPring-8 storage ring during beam commissioning. In order to confirm the stability of the radio frequency (RF) synthesizer, a monitoring system was developed. The system consists of a frequency counter referenced to a global positioning system (GPS) receiver. With this system, the output of the synthesizer, which uses an external 10 MHz-Rubidium atomic clock with the time accuracy of Delta t/t = 10(-12), is correctly monitored with 11 digits absolute accuracy, verifying that the synthesizer works well. Measurement of the circumference of the SPring-8 storage ring reveals the effect of tidal forces and seasonal temperature variations on beam orbit. To maintain the center axis of photon radiation in experimental beam lines, a beam energy correction is carried out. The frequency of the RF synthesizer is changed every 5 min with 10-digit accuracy. This corresponds to an energy accuracy of Delta E/E = 1.16 x 10(-6). The monitoring system for the synthesizer and obtained results are described. Published by Elsevier B.V.

In this paper we ask if new physics associated with Partial Compositeness could plausibly explain this result. We find that Composite Higgs models with mass scale around 10 TeV can account for it, while marginally satisfying all other flavor constraints in the quark sector. The minimal framework is however inadequate in the lepton sector due to the strong constraint from mu -> e gamma. This tension can be efficiently alleviated by realizing Partial Compositeness within Supersymmetry. The resulting models can saturate the CP asymmetry in D decays for superpartner masses close to the TeV scale and somewhat large A-terms. The supersymmetric realization of Partial Compositeness also offers a predictive and phenomenologically viable organizing principle for R-parity violation, and may result in very distinctive signatures at hadron colliders. With or without Supersymmetry, the neutron EDM is expected to be around the present experimental sensitivity. (C) 2012 Elsevier B.V. All rights reserved.

TI DISCOVERY OF TeV GAMMA-RAY EMISSION FROM CTA 1 BY VERITAS SO ASTROPHYSICAL JOURNAL LA English DT Article DE gamma-rays: stars; pulsars: individual (PSR J0007+7303); supernovae: individual (G119.5+10.2); X-rays: individual (RX J0007.0+7303) ID PULSAR-WIND NEBULAE; ATMOSPHERIC CHERENKOV TELESCOPES; SUPERNOVA REMNANT CTA-1; X-RAY; HESS J1825-137; CRAB-NEBULA; CATALOG; PULSATIONS; EVOLUTION; ASTRONOMY AB We report the discovery of TeV gamma-ray emission coincident with the shell-type radio supernova remnant (SNR) CTA 1 using the VERITAS gamma-ray observatory. The source, VER J0006+729, was detected as a 6.5 standard deviation excess over background and shows an extended morphology, approximated by a two-dimensional Gaussian of semimajor (semiminor) axis 0.degrees 30 (0.degrees 24) and a centroid 5' from the Fermi gamma-ray pulsar PSR J0007+7303 and its X-ray pulsar wind nebula (PWN). The photon spectrum is well described by a power-law dN/dE = N-0(E/3 TeV)(-Gamma), with a differential spectral index of Gamma = 2.2 +/- 0.2(stat) +/- 0.3(sys), and normalization N-0 = (9.1 +/- 1.3(stat) +/- 1.7(sys)) x 10(-14) cm(-2) s(-1) TeV-1. The integral flux, F-gamma = 4.0 x 10(-12) erg cm(-2) s(-1) above 1 TeV, corresponds to 0.2% of the pulsar spin-down power at 1.4 kpc. The energetics, colocation with the SNR, and the relatively small extent of the TeV emission strongly argue for the PWN origin of the TeV photons. We consider the origin of the TeV emission in CTA 1.

TI TESTING MODELS OF INTRINSIC BRIGHTNESS VARIATIONS IN TYPE Ia SUPERNOVAE AND THEIR IMPACT ON MEASURING COSMOLOGICAL PARAMETERS SO ASTROPHYSICAL JOURNAL LA English DT Article DE dark energy; supernovae: general ID DIGITAL SKY SURVEY; LEGACY SURVEY; LIGHT CURVES; DARK ENERGY; DISTANCE MODULI; HUBBLE DIAGRAM; HOST GALAXIES; CONSTRAINTS; SPECTRA; TELESCOPE AB For spectroscopically confirmed Type Ia supernovae we evaluate models of intrinsic brightness variations with detailed data/Monte Carlo comparisons of the dispersion in the following quantities: Hubble-diagram scatter, color difference (B - V - c) between the true B-V color and the fitted color (c) from the SALT-II light curve model, and photometric redshift residual. The data sample includes 251 ugriz light curves from the three-season Sloan Digital Sky Survey-II and 191 griz light curves from the Supernova Legacy Survey 3 year data release. We find that the simplest model of a wavelength-independent (coherent) scatter is not adequate, and that to describe the data the intrinsic-scatter model must have wavelength-dependent variations resulting in a similar to 0.02 mag scatter in B - V - c. Relatively weak constraints are obtained on the nature of intrinsic scatter because a variety of different models can reasonably describe this photometric data sample. We use Monte Carlo simulations to examine the standard approach of adding a coherent-scatter term in quadrature to the distance-modulus uncertainty in order to bring the reduced chi(2) to unity when fitting a Hubble diagram. If the light curve fits include model uncertainties with the correct wavelength dependence of the scatter, we find that this approach is valid and that the bias on the dark energy equation-of-state parameter w is much smaller (similar to 0.001) than current systematic uncertainties. However, incorrect model uncertainties can lead to a significant bias on the distance moduli, with up to similar to 0.05 mag redshift-dependent variation. This bias is roughly reduced in half after applying a Malmquist bias correction. For the recent SNLS3 cosmology results, we estimate that this effect introduces an additional systematic uncertainty on w of similar to 0.02, well below the total uncertainty. This uncertainty depends on the choice of viable scatter models and the choice of supernova (SN) samples, and thus this small w-uncertainty is not guaranteed in future cosmology results. For example, the w-uncertainty for SDSS+SNLS (dropping the nearby SNe) increases to similar to 0.04.

TI THE CONTRIBUTION OF THERMALLY-PULSING ASYMPTOTIC GIANT BRANCH AND RED SUPERGIANT STARS TO THE LUMINOSITIES OF THE MAGELLANIC CLOUDS AT 1-24 mu m SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: fundamental parameters; galaxies: stellar content; stars: AGB and post-AGB ID HIGH-REDSHIFT GALAXIES; MASS-LOSS RATES; RICH AGB-STARS; STELLAR MASS; TP-AGB; NEARBY GALAXIES; LOW METALLICITY; CENTIMETER EXCESS; FORMATION HISTORY; SPACE-TELESCOPE AB We present the near-through mid-infrared flux contribution of thermally-pulsing asymptotic giant branch (TP-AGB) and massive red supergiant (RSG) stars to the luminosities of the Large and Small Magellanic Clouds (LMC and SMC, respectively). Combined, the peak contribution from these cool evolved stars occurs at similar to 3-4 mu m, where they produce 32% of the SMC light, and 25% of the LMC flux. The TP-AGB star contribution also peaks at similar to 3-4 mu m and amounts to 21% in both galaxies. The contribution from RSG stars peaks at shorter wavelengths, 2.2 mu m, where they provide 11% of the SMC flux, and 7% for the LMC. Both TP-AGB and RSG stars are short lived, and thus potentially impose a large stochastic scatter on the near-IR derived mass-to-light (M/L) ratios of galaxies at rest-frame 1-4 mu m. To minimize their impact on stellar mass estimates, one can use the M/L ratio at shorter wavelengths (e. g., at 0.8-1 mu m). At longer wavelengths (>= 8 mu m), emission from dust in the interstellar medium dominates the flux. In the LMC, which shows strong polycyclic aromatic hydrocarbon (PAH) emission at 8 mu m, TP-AGB and RSG contribute less than 4% of the 8 mu m flux. However, 19% of the SMC 8 mu m flux is from evolved stars, nearly half of which is produced by the rarest, dustiest, carbon-rich TP-AGB stars. Thus, star formation rates of galaxies, based on an 8 mu m flux (e. g., observed-frame 24 mu m at z = 2), may be biased modestly high, especially for galaxies with little PAH emission.

TI X-RAY OBSERVATIONS OF HIGH-B RADIO PULSARS SO ASTROPHYSICAL JOURNAL LA English DT Article DE pulsars: general; pulsars: individual (PSR B1845-19, PSR J1001-5939, PSR J1734-3333); stars: neutron; X-rays: stars ID SOFT GAMMA-REPEATERS; MAGNETIZED NEUTRON-STARS; PHOTON IMAGING CAMERA; XMM-NEWTON; SWIFT J1822.3-1606; SPIN-DOWN; EMISSION; DISCOVERY; POPULATION; YOUNG AB The study of high-magnetic-field pulsars is important for examining the relationships between radio pulsars, magnetars, and X-ray-isolated neutron stars (XINSs). Here, we report on X-ray observations of three such high-magnetic-field radio pulsars. We first present the results of a deep XMM-Newton observation of PSR J1734-3333, taken to follow up on its initial detection in 2009. The pulsar's spectrum is well fit by a blackbody with a temperature of 300 +/- 60 eV, with bolometric luminosity L-bb = 2.0(-0.7)(+2.2) x 10(32) erg s(-1) approximate to 0.0036 (E) over dot for a distance of 6.1 kpc. We detect no X-ray pulsations from the source, setting a 1 sigma upper limit on the pulsed fraction of 60% in the 0.5-3 keV band. We compare PSR J1734-3333 to other rotation-powered pulsars of similar age and find that it is significantly hotter, supporting the hypothesis that the magnetic field affects the observed thermal properties of pulsars. We also report on XMM-Newton and Chandra observations of PSRs B1845-19 and J1001-5939. We do not detect either pulsar, setting 3 sigma upper limits on their blackbody temperatures of 48 and 56 eV, respectively. Despite the similarities in rotational properties, these sources are significantly cooler than all but one of the XINSs, which we attribute to the two groups having been born with different magnetic fields and hence evolving differently.

Although this flattening in slope is hinted at in a few other SNe, due to its proximity and minimal line-of-sight extinction, SN 2012aw has afforded the first opportunity to clearly observe this UV plateau. The observations of SN 2012aw revealed all Swift UV and u-band light curves initially declined rapidly, but 27 days after the explosion the light curves flattened. Some possible sources of the UV plateau are the same thermal process that causes the optical plateau, heating from radioactive decay, or a combination of both processes.

The model is formulated in the spirit of multiscale finite element methods (FE 2), that is, the macroscopic behavior of the material is obtained by a simultaneous numerical evaluation of the response of a representative volume element. The representative microscopic model considered in this work consists of a space-filling assemblage of hollow spheres. Accordingly, we refer to the present model as the packed hollow sphere (PHS) model. A RitzGalerkin method based on spherical harmonics, specialized quadrature rules, and exact boundary conditions is employed to discretize individual voids at the microscale. This discretization results in material frame indifference, and it exactly preserves all material symmetries. The effective macroscopic behavior is then obtained by recourse to Hill's averaging theorems. The deformation and stress fields of the hollow spheres are globally kinematically and statically admissible regardless of material constitution and deformation history, which leads to exact solutions over the entire representative volume under static conditions. Excellent convergence and scalability properties of the PHS model are demonstrated through convergence analyses and examples of application. We also illustrate the broad range of material behaviors that are captured by the PHS model, including elastic and plastic cavitation and the formation of a vertex in the yield stress of porous metals at low triaxiality. This vertex allows ductile damage to occur under shear-dominated conditions, thus overcoming a well-known deficiency of Gurson's model. Copyright (c) 2012 John Wiley & Sons, Ltd.

For a regularized version of the initial-boundary value problem for an associated linear system, with time-dependent boundary conditions, Galerkin approximations are used to establish the existence of a suitable class of unique solutions. Standard parabolic theory is then employed to established higher regularity for the solutions of the regularized problem. Finally, a priori estimates are derived which allow for letting the artificial viscosity, in the regularized system, approach zero so as to obtain the existence of a unique solution for the original mixed hyperbolic-parabolic problem.

TI Formation and Stability of Impurity "Snakes" in Tokamak Plasmas SO PHYSICAL REVIEW LETTERS LA English DT Article ID DENSITY PERTURBATIONS; PELLET INJECTION AB New observations of the formation and dynamics of long-lived impurity-induced helical "snake'' modes in tokamak plasmas have recently been carried out on Alcator C-Mod. The snakes form as an asymmetry in the impurity ion density that undergoes a seamless transition from a small helically displaced density to a large crescent-shaped helical structure inside q < 1, with a regularly sawtoothing core. The observations show that the conditions for the formation and persistence of a snake cannot be explained by plasma pressure alone. Instead, many features arise naturally from nonlinear interactions in a 3D MHD model that separately evolves the plasma density and temperature.

TI Effects of Preplasma Scale Length and Laser Intensity on the Divergence of Laser-Generated Hot Electrons SO PHYSICAL REVIEW LETTERS LA English DT Article ID PLASMA; FIELD; GAIN AB We report on a numerical study of the effects of preplasma scale length and laser intensity on the hot-electron (>= 1 MeV) divergence angle using full-scale 2D3V (two dimensional in space, three dimensional in velocity) simulations including a self-consistent laser-plasma interaction and photoionization using the particle-in-cell code LSP. Our simulations show that the fast-electron divergence angle increases approximately linearly with the preplasma scale length for a fixed laser intensity. On the other hand, for a fixed preplasma scale length, the laser intensity has little effect on the divergence angle in the range between 10(18) and 10(21) W/cm(2). These findings have important implications for the interpretation of experimental results. DOI: 10.1103/PhysRevLett.110.065007 C1 [Ovchinnikov, V. M.; Schumacher, D. W.; McMahon, M.; Chowdhury, E.

TI Field mapping and temperature dependence of magnetic domain memory induced by exchange couplings SO NEW JOURNAL OF PHYSICS LA English DT Article ID X-RAY; FERROMAGNETIC HYSTERESIS; SCATTERING AB Strong magnetic domain memory is achieved in [Co/Pd] IrMn exchange-biased ferromagnetic thin films when zero-field-cooled (ZFC) below their blocking temperature T-B. By mapping out the amount of memory throughout the entire magnetization cycle, from nucleation to saturation, at different temperatures below and above T-B, we discover how microscopic morphological changes in the magnetic domain patterns correlate with the macroscopic magnetic hysteresis, in the presence or absence of exchange couplings. Our unique inter-field correlation maps show that in the ZFC state, the film exhibits the highest amount of domain memory, exceeding 90%, when domain patterns are compared at the same field value, in the coercive region of the magnetization loop. However, domain patterns also cross-correlate surprisingly well when measured at different field values, on a wide field range centered about the coercive region. The shape and symmetry of the correlation maps provide further insights into the microscopic morphological changes in the domain patterns and the amount of reversibility in the reversal process, at the nanoscale.

In particular, we show that by ramping up the phase of the complex tunneling coefficient in a spatially uniform fashion, a finite quasi-steady-state current (QSSC) ensues from the exact dynamics of noninteracting fermions. The direction and magnitude of the current can be controlled by the overall phase difference but not the details of the ramp. The entanglement entropy does not increase when the QSSC lasts. Due to different spin statistics, condensed noninteracting bosons do not support a finite QSSC under the same setup. We also find that an approximate form of the QSSC survives when perturbative effects from interactions, weak harmonic background traps, and finite temperature are present, which suggests that our findings should be observable with available experimental capabilities.

We extend existing work by calculating the third and fourth moment beyond the harmonic approximation and show that NRIXS can provide a direct measurement of the anharmonic terms in lattice potentials. Projected partial phonon density of states (ppDOS) extracted from measured spectra provide vibrational mode-specific information on lattice dynamics. Furthermore, unique contributions to thermodynamic properties can be defined and calculated as the moments and other weighted integrals of ppDOS. A summary of some of these thermodynamic quantities is given. The directional dependence of NRIXS and its effects are emphasized. We derive explicit relationships between the moments of phonon excitation probability function and those of ppDOS. The comparison between the two sets of moments provides a consistency check and insights to the lattice dynamics of the system under study.

TI RPA analysis of a two-orbital model for the BiS2-based superconductors SO PHYSICAL REVIEW B LA English DT Article ID LAYERED SUPERCONDUCTOR; BI4O4S3 AB The random-phase approximation (RPA) is here applied to a two-orbital model for the BiS2-based superconductors that was recently proposed by Usui et al. [Phys. Rev. B 86, 220501(R) (2012)]. Varying the density of doped electrons per Bi site n in the range 0.46 <= n <= 1.0, the spin fluctuations promote competing A(1g) and B-2g superconducting states with similar pairing strengths, in analogy with the A(1g)-B-1g near degeneracy found also within RPA in models for pnictides. At these band fillings, two hole pockets centered at (0,0) and (p, p) display nearly parallel Fermi-surface segments close to wave vector (pi/2,p/2), whose distance increases with n. After introducing electronic interactions treated in the RPA, the interpocket nesting of these segments leads to pair scattering with a rather "local" character in k space. The similarity between the A(1g) and B-2g channels observed here should manifest in experiments on BiS2-based superconductors if the pairing is caused by spin fluctuations.

To understand their influence on phonon scattering, and thus thermal conductivity, we explored the effect of interfacial strain fields (ISFs) on interfaces with a different misfit between the two dissimilar lattices comprising the interface. We found that phonon scattering depends strongly on the frequency of the incident phonon wave; phonons with frequencies below a critical value pass transparently through the strain zone of the interfaces. Our calculations suggest that the classical acoustic mismatch model (AMM) and the diffusive mismatch model (DMM) represent the two extreme limits of phonon scattering, and that, in reality, scattering lies between these limits. For long-wavelength (low-frequency) phonons, the AMM adequately describes the thermal conductivity of the interfaces. As the frequency of the incident phonons increases, phonon scattering becomes progressively more diffuse to the point where the DMM represents the dominant mechanism for thermal conductivity. Furthermore, we noted that phonon scattering from the interfacial strain field can lower thermal conductivity effectively at high temperatures. We discuss the implications of our findings in explaining the experimental observations of thermal conductivity across precipitates and grain boundaries in thermoelectric materials.

TI Electric field modulation of the tetragonal domain orientation revealed in the magnetic ground state of quantum paraelectric EuTiO3 SO PHYSICAL REVIEW B LA English DT Article ID TITANATE; TRANSITION AB We present a study of the thermodynamic and magnetic properties of single-crystal EuTiO3. Signatures of metastability are visible in the heat capacity below the cubic-tetragonal phase transition at 283 K, supporting the evidence for a mismatch between long and short range structural order from previous x-ray diffraction studies. Employing the anisotropic magnetization as an indirect structural probe, we confirm the emergence of multiple orthogonal domains at low temperature. Torque magnetometry is capable of revealing the nature and temperature dependence of the magnetic anisotropy in spite of the domain misalignment; we hence deduce that tetragonal EuTiO3 enters an easy-axis antiferromagnetic phase at 5.6 K, with a first-order phase transition to an easy-plane ground state below 3 K. Our experimentally determined magnetic phase diagram is accurately reproduced by a three-dimensional (3D) anisotropic Heisenberg spin model. Furthermore, we demonstrate that electric field cooling acts to suppress this orientational disorder by realigning the domains due to the strong coupling between electric fields and lattice dipoles characteristic of paraelectric materials.

TI Direct determination of the strange and light quark condensates from full lattice QCD SO PHYSICAL REVIEW D LA English DT Article ID DIRAC OPERATOR; SYMMETRY-BREAKING; SUM-RULES; CORRELATORS; SPECTRUM; FERMIONS; PHYSICS; MASS AB We determine the strange quark condensate from lattice QCD for the first time and compare its value to that of the light quark and chiral condensates. The results come from a direct calculation of the expectation value of the trace of the quark propagator followed by subtraction of the appropriate perturbative contribution, derived here, to convert the non-normal-ordered m (psi) over bar psi to the (MS) over bar scheme at a fixed scale. This is then a well-defined physical "nonperturbative'' condensate that can be used in the operator product expansion of current-current correlators. The perturbative subtraction is calculated through O(alpha(s)) and estimates of higher order terms are included through fitting results at multiple lattice spacing values. The gluon field configurations used are "second generation'' ensembles from the MILC collaboration that include 2 + 1 + 1 flavors of sea quarks implemented with the highly improved staggered quark action and including u/d sea quarks down to physical masses. Our results are <(s) over bars >((MS) over bar)(2 GeV) = -(290(15) MeV)(3), <(l) over barl >((MS) over bar)(2 GeV) = -(283(2) MeV)(3), where l is a light quark with mass equal to the average of the u and d quarks. The strange to light quark condensate ratio is 1.08 (16). The light quark condensate is significantly larger than the chiral condensate in line with expectations from chiral analyses. We discuss the implications of these results for other calculations. DOI: 10.1103/PhysRevD.87.034503 C1 [McNeile, C.] Berg Univ Wuppertal, D-42119 Wuppertal, Germany.

TI Proton Donor Acidity Controls Selectivity in Nonaromatic Nitrogen Heterocycle Synthesis SO SCIENCE LA English DT Article ID C-H FUNCTIONALIZATION; ACTIVATION; CASCADE; BONDS AB Piperidines are prevalent in natural products and pharmaceutical agents and are important synthetic targets for drug discovery and development. We report on a methodology that provides highly substituted piperidine derivatives with regiochemistry selectively tunable by varying the strength of acid used in the reaction. Readily available starting materials are first converted to dihydropyridines via a cascade reaction initiated by rhodium-catalyzed carbon-hydrogen bond activation. Subsequent divergent regio- and diastereoselective protonation of the dihydropyridines under either kinetic or thermodynamic control provides two distinct iminium ion intermediates that then undergo highly diastereoselective nucleophilic additions. X-ray structural characterization of both the kinetically and thermodynamically favored iminium ions along with density functional theory calculations provide a theoretical underpinning for the high selectivities achieved for the reaction sequences.

TI Band gaps of graphene on layered ZnO substrate: A first principles study SO JOURNAL OF APPLIED PHYSICS LA English DT Article AB Using density functional theory, we show that the band gap of graphene can be induced via deposition on a layered ZnO substrate. This phenomenon can be understood based on the symmetry-breaking substrate potential, which leads to the nonequivalence of sublattices in graphene. With the decrease of interlayer spacing, the band gap of graphene was improved, while the electron effective mass (EEM) increases and the carrier mobility decreases. The finding of large Fermi velocity, which is comparable to that of an isolated graphene, retards the increase of EEM with the band gap, and thus, provides a possible way to design the graphene-based field-effect transistors.

In addition, the surface exchange coefficients were determined over the same temperature ranges. The transport properties and exchange kinetics of SSC are comparable to or better than those of other solid oxide fuel cell cathode candidates in the literature. The ionic conductivity of SSC was calculated using the Nernst-Einstein equation, and is comparable to that of leading solid oxide electrolytes at intermediate temperatures. (C) 2012 Elsevier B.V.

The radical was produced by flash pyrolysis of dimethyl disulfide (CH3SSCH3). Two channels were observed: CH3 + S-2 and CH2S + SH. Photofragment translational energy distributions indicate that CH3 + S-2 results from C-S bond fission on the ground state surface. The CH2S + SH channel can proceed through isomerization to CH2SSH on the ground state surface but also may involve production of electronically excited CH2S. (C) 2013 American Institute of Physics.

Motivated by a conceptual bridging of the DB phenomena in classical and quantum mechanical representations, we study their signatures in the dynamics of a quantum equivalent of a classical mechanical point in phase space - a coherent state. In contrast to the classical point that exhibits either delocalized or localized motion, the coherent state shows signatures of both localized and delocalized behavior. The transition from normal to local modes have different characteristics in quantum and classical perspectives. Here, we get an insight into the connection between classical and quantum perspectives by analyzing the decomposition of the coherent state into system's eigenstates, and analyzing the spacial distribution of the wave-function density within these eigenstates. We find that the delocalized and localized eigen-value components of the coherent state are separated by a mixed region, where both kinds of behavior can be observed. Further analysis leads to the following observations. Considered as a function of coupling, energy eigenstates go through avoided crossings between tunneling and non-tunneling modes. The dominance of tunneling modes in the high nonlinearity region is compromised by the appearance of new types of modes - high order tunneling modes - that are similar to the tunneling modes but have attributes of non-tunneling modes. Certain types of excitations preferentially excite higher order tunneling modes, allowing one to study their properties. Since auto-correlation functions decrease quickly in highly nonlinear systems, short-time dynamics are sufficient for modeling quantum DBs. This work provides a foundation for implementing modern semi-classical methods to model quantum DBs, bridging classical and quantum mechanical signatures of DBs, and understanding spectroscopic experiments that involve a coherent state.

This difference in the IR intensities of the HOH bend in the two systems is investigated using Molecular Dynamics (MD) simulations with the flexible, polarizable, ab initio based TTM3-F model for water, a potential that correctly reproduces the experimentally observed increase of the HOH angle in liquid water and ice from the water monomer value. We have identified two factors that are responsible for the difference in the intensity of the HOH bend in liquid water and ice: (i) the decrease of the intensity of the HOH bend in ice caused by the strong anti-correlation between the permanent dipole moment of a molecule and the induced dipole moment of neighboring hydrogen bond acceptor molecules, and (ii) the weakening of this anti-correlation by the disordered hydrogen bond network in liquid water. The presence of the anti-correlation in ice is further confirmed by ab initio electronic structure calculations of water pentamer clusters extracted from the trajectories of the MD simulations with the TTM3-F potential for ice and liquid water.

The 2D master equation was used at the P = 0 and P = infinity limits, while the ID master equation with centrifugal corrections and an empirical energy transfer parameter could be used over the entire pressure range. Rate constants were computed for 75 K <= T <= 2500 K and 0 <= [He] <= 10(23) cm(-3). For all temperatures and pressures important for combustion and for the terrestrial atmosphere, the agreement with the experimental rate constants is very good, but at very high pressures and T <= 200 K, the theoretical rate constants are significantly smaller than the experimental values. This effect is possibly due to the presence in the experiments of dimers and prereactive complexes, which were not included in the model calculations. The computed H/D kinetic isotope effects are in acceptable agreement with experimental data, which show considerable scatter. Overall, the agreement between experimental and theoretical H/D kinetic isotope effects is much better than in previous work, and an assumption of non-RRKM behavior does not appear to be needed to reproduce experimental observations.

By monitoring the evolution of shear viscosity with time, rate constants for mutarotation were estimated, and two different stages of this reaction were identified. One of the mutarotation stages is rapid and has a low activation energy, whereas the other is much slower and has a much higher activation energy. Possible conversions corresponding to these two phases are discussed. This work demonstrates that, in addition to the routine techniques such polarimetry and gas-liquid chromatography, rheological measurement can be used as an alternative method to continuously monitor the mutarotation of sugars.

TI Electron Exchange and Conduction in Nontronite from First-Principles SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID OXIDATION-REDUCTION MECHANISM; INITIO MOLECULAR-DYNAMICS; CHARGE-TRANSFER PROCESSES; GAUSSIAN-BASIS SETS; AB-INITIO; DIOCTAHEDRAL SMECTITES; GARFIELD NONTRONITE; FERRUGINOUS SMECTITE; HEMATITE SURFACES; CRYSTAL-CHEMISTRY AB Fe-bearing clay minerals serve as an important source and sink for electrons in redox reactions in various subsurface geochemical environments. We apply first-principles calculations using a small polaron hopping approach and Marcus electron transfer theory to examine electron exchange mobilities in an Fe-rich smectite, nontronite Fe2Si4O10(OH)(2). GGA+U calculations provide rates of electron hopping that agree very well with values deduced from variable-temperature Mossbauer data (Schaefer et al. Environ. Sci. Technol. 2011, 45, 540), indicating a surprisingly fast electron mobility at room temperature. Evaluation of the electron transfer (ET) rates within the Hartree-Fock cluster framework for the Fe2+/Fe3+ electron hopping in tetrahedral (TS) and octahedral sheets (OS), as well as across the sheets (TS-OS), shows that the dominant contribution to the bulk electronic conductivity should come from the ET within the OS. Deprotonation of structural OH groups mediating ET between the Fe ions in the OS is found to decrease the internal reorganization energy and to increase the electronic coupling, whereas protonation (to OH2 groups) has the opposite effect. Our calculations suggest that the major factors affecting ET rates are the nature and structure of the nearest-neighbor local environment and the degree of covalency of the bonds between Fe and ligands mediating electron hops. The generally higher reorganization energy and weaker electronic coupling found in Fe-bearing day minerals lead to electron mobilities much lower than in iron oxides.

For CO coadsorbed with a saturation coverage of chemisorbed O-2 (theta(sat)), the CO2 photon-stimulated desorption (PSD) signal is initially zero, increases to a maximum after several tens of milliseconds, and then decreases at longer times. The initial CO, PSD signal increases similar to 5 times more quickly for an oxygen coverage of 0.5 theta(sat). The initial rate of increase of the CO2 PSD signal is proportional to the flux of UV photons. The results show that two or more nonthennal reaction steps are required to photooxidize CO adsorbed on TiO2(110). The intermediate species involved in the reactions is stable for at least 100 s at 30 K Previous models had suggested that CO photooxidation required only one nonthermal reaction. The likely initial and final charge states of the system suggest that an electron-mediated reaction and a hole-mediated reaction are needed for the complete photooxidation reaction.

Here, we characterize a low-lying water elimination pathway from key hydroperoxyalkyl (QOOH) radicals derived from alcohols. The corresponding saddle-point structure involves the interaction of radical and zwitterionic electronic states. This interaction presents extreme difficulties for electronic structure characterizations, but we demonstrate that these properties of this saddle point can be well captured by M06-2X and CCSD(T) methods. Experimental evidence for the existence and relevance of this pathway is shown in recently reported data on the low-temperature oxidation of isopentanol and isobutanol. In these systems, water elimination is a major pathway, and is likely ubiquitous in low-temperature alcohol oxidation. These findings will substantially alter current alcohol oxidation mechanisms. Moreover, the methods described will be useful for the more general phenomenon of interacting radical and zwitterionic states.

TI Engineered CuInSexS2-x Quantum Dots for Sensitized Solar Cells SO JOURNAL OF PHYSICAL CHEMISTRY LETTERS LA English DT Article ID CUINS2 NANOCRYSTALS; CDSE NANOCRYSTALS; CATION-EXCHANGE; EFFICIENCY; DYE AB Colloidal CuInSexS2-x quantum dots (QDs) are an attractive less-toxic alternative to PbX and CdX (X = S, Se, and Te) QDs for solution-processed semiconductor devices. This relatively new class of QD materials is particularly suited to serving as an absorber in photovoltaics, owing to its high absorption coefficient and near-optimal and finely tunable band gap. Here, we engineer CuInSexS2-x QD sensitizers for enhanced performance of QD-sensitized TiO2 solar cells (QDSSCs). Our QD synthesis employs 1-dodecanethiol (DDT) as a low-cost solvent, which also serves as a ligand, and a sulfur precursor; addition of triakylphosphine selenide leads to incorporation of controlled amounts of selenium, reducing the band gap compared to that of pure CuInS2 QDs. This enables significantly higher photocurrent in the near-infrared (IR) region of the solar spectrum without sacrificing photovoltage. In order to passivate QD surface recombination centers, we perform a surface-cation exchange with Cd prior to sensitization, which enhances chemical stability and leads to a further increase in photocurrent. We use the synthesized QDs to demonstrate proof-of-concept QDSSCs with up to 3.5% power conversion efficiency.

Nearly every main-group element (E) that surrounds Ge on the periodic table (Al, P, Ga, As, In, Sn, and Sb) may be incorporated into Ge1-xEx NCs with remarkably high E incorporation into the product (>45% of E. added to the reaction). Importantly, surface chemistry modification via ligand exchange allowed conductive films of Ge1-xEx NCs to be prepared, which exhibit conductivities over large distances (25 mu m) relevant to optoelectronic device development of group IV NC thin films.

When photoexcited, charge is injected into the conduction band directly from their highest occupied molecular orbital (HOMO) without needing mediation by the lowest unoccupied molecular orbital (LUMO). In this study, we successfully induce the chemical participation of carbon dioxide in a charge transfer state using 3-aminosalicylic acid (3ASA). We determine the geometry of CO2 using a combination of ultraviolet-visible spectroscopy (UV-vis), surface enhanced Raman scattering (SERS), C-13 NMR, and electron paramagnetic resonance (EPR). We find CO2 binds on Ti sites in a carbonate form and discern via EPR a surface Ti-centered radical in the vicinity of CO2, suggesting successful charge transfer from the sensitizer to the neighboring site of CO2. This study opens the possibility of analyzing the structural and electronic properties of the anchoring sites for CO2 on semiconducting surfaces and proposes a set of tools and experiments to do so.

However, UV irradiation of NOx adsorbed on TiO2 also was shown to form harmful gas-phase byproducts such as HONO and N2O that may limit their depolluting potential. Ambient pressure XPS was used to study surface and gas-phase species formed during adsorption of NO2 on TiO2 and subsequent UV irradiation at lambda = 365 nm. It is shown here that NO3-, adsorbed on TiO2 as a byproduct of NO2 disproportionation, was quantitatively converted to surface NO2 and other reduced nitrogenated species under UV irradiation in the absence of moisture. When water vapor was present, a faster NO3- conversion occurred, leading to a net loss of surface-bound nitrogenated species. Strongly adsorbed NO3- in the vicinity of coadsorbed K+ cations was stable under UV light, leading to an efficient capture of nitrogenated compounds.

This experiment used one beam in a resonator and one in free space due to limitations related to device physics. These results suggest that a similar scheme with both beams resonant in the cavity would correspond to input power levels below 150 nW. DOI: 10.1103/PhysRevA.87.023808 C1 [Hendrickson, S.

TI Effect of vortex hotspots on the radio-frequency surface resistance of superconductors SO PHYSICAL REVIEW B LA English DT Article ID SCANNING ELECTRON-MICROSCOPY; THERMAL-CONDUCTIVITY; NIOBIUM FILMS; SINGLE-PHOTON; 1.5 GHZ; TRANSITION; METALS; STATE; FREQUENCY; VORTICES AB We present detailed experimental and theoretical investigations of hotspots produced by trapped vortex bundles and their effect on the radio-frequency (rf) surface resistance R-s of superconductors at low temperatures. Our measurements of R-s, combined with the temperature mapping and laser scanning of a 2.36-mm-thick Nb plate incorporated into a 3.3-GHz Nb resonator cavity cooled by the superfluid He at 2 K, revealed spatial scales and temperature distributions of hotspots and showed that they can be moved or split by thermal gradients produced by the scanning laser beam. These results, along with the observed hysteretic field dependence of R-s which can be tuned by the scanning laser beam, show that the hotspots in our Nb sample are due to trapped vortex bundles which contain similar to 10(6) vortices spread over regions similar to 0.1-1 cm. We calculated the frequency dependence of the rf power dissipated by oscillating vortex segments trapped between nanoscale pinning centers, taking into account all bending modes and the nonlocal line tension of the vortex driven by rf Meissner currents. We also calculated the temperature distributions caused by trapped vortex hotspots, and suggested a method of reconstructing the spatial distribution of vortex dissipation sources from the observed temperature maps. Vortex hotspots can dominate the residual surface resistance at low temperatures and give rise to a significant dependence of R-s on the rf field amplitude H-p, which can have important implications for the rf resonating cavities used in particle accelerators and for thin-film structures used in quantum computing and photon detectors.

TI Enhanced Localized Energetic-Ion Losses Resulting from Single-Pass Interactions with Alfven Eigenmodes SO PHYSICAL REVIEW LETTERS LA English DT Article ID TRANSPORT; TOKAMAK AB We report the first observation of prompt neutral beam-ion losses due to nonresonant scattering induced by toroidal and reversed shear Alfven eigenmodes in the DIII-D tokamak. The coherent losses are of full energy beam ions expelled from the plasma on their first poloidal orbit. The first-orbit loss mechanism causes enhanced, concentrated losses on the first wall exceeding nominal levels of prompt losses. The loss amplitude scales linearly with the mode amplitude. The data provide a novel and direct measure of the radial excursion or scatter of particles induced by individual modes and may shed light on the mechanism for the scattering of energetic particles in interstellar medium.

CA KamLAND-Zen Collaboration TI Limit on Neutrinoless beta beta Decay of Xe-136 from the First Phase of KamLAND-Zen and Comparison with the Positive Claim in Ge-76 SO PHYSICAL REVIEW LETTERS LA English DT Article AB We present results from the first phase of the KamLAND-Zen double-beta decay experiment, corresponding to an exposure of 89.5 kg yr of Xe-136. We obtain a lower limit for the neutrinoless double-beta decay half-life of T(1/2)0(v) > 1.9 x 10(25) yr at 90% C.L. The combined results from KamLAND-Zen and EXO-200 give T(1/2)0(v) > 3.4 x 10(25) yr at 90% C.L., which corresponds to a Majorana neutrino mass limit of < m(beta beta)> < (120- 250) meV based on a representative range of available matrix element calculations. Using those calculations, this result excludes the Majorana neutrino mass range expected from the neutrinoless double-beta decay detection claim in Ge-76, reported by a part of the Heidelberg-Moscow Collaboration, at more than 97.5% C.L.

TI Terahertz Conductivity of Twisted Bilayer Graphene SO PHYSICAL REVIEW LETTERS LA English DT Article ID TIME-DOMAIN SPECTROSCOPY; FILMS AB Using terahertz time-domain spectroscopy, the real part of optical conductivity [sigma(1)(omega)] of twisted bilayer graphene was obtained at different temperatures (10-300 K) in the frequency range 0.3-3 THz. On top of a Drude-like response, we see a strong peak in sigma(1)(omega) at similar to 2.7 THz. We analyze the overall Drude-like response using a disorder-dependent (unitary scattering) model, then attribute the peak at 2.7 THz to an enhanced density of states at that energy, which is caused by the presence of a van Hove singularity arising from a commensurate twisting of the two graphene layers.

TI An outburst from a massive star 40 days before a supernova explosion SO NATURE LA English DT Article ID COMMON ENVELOPE EVOLUTION; LUMINOUS SUPERNOVA; DISCOVERY; SN-2006GY; WIND AB Some observations suggest that very massive stars experience extreme mass-loss episodes shortly before they explode as supernovae(1-4), as do several models(5-7). Establishing a causal connection between these mass-loss episodes and the final explosion would provide a novel way to study pre-supernova massive-star evolution. Here we report. observations of a mass-loss event detected 40 days before the explosion of the type IIn supernova SN 2010mc (also known as PTF 10tel). Our photometric and spectroscopic data suggest that this event is a result of an energetic outburst, radiating at least 6 x 10(47) erg of energy and releasing about 10(-2) solar masses of material at typical velocities of 2,000 km s(-1). The temporal proximity of the mass-loss outburst and the supernova explosion implies a causal connection between them. Moreover, we find that the outburst luminosity and velocity are consistent with the predictions of the wave-driven pulsation model(6), and disfavour alternative suggestions(7). C1 [Ofek, E.

TI Antiferromagnetism in EuNiGe3 SO PHYSICAL REVIEW B LA English DT Article ID MAGNETIC-STRUCTURE; ND; CRYSTAL; SERIES; SM; NI; LU AB The synthesis and crystallographic and physical properties of polycrystalline EuNiGe3 are reported. EuNiGe3 crystallizes in the noncentrosymmetric body-centered tetragonal BaNiSn3-type structure (space group I4mm), in agreement with previous reports, with the Eu atoms at the corners and body center of the unit cell. The physical property data consistently demonstrate that this is a metallic system in which Eu spins S = 7/2 order antiferromagnetically at a temperature T-N = 13.6 K. Magnetic susceptibility chi data for T > T-N indicate that the Eu atoms have spin 7/2 with g = 2, that the Ni atoms are nonmagnetic, and that the dominant interactions between the Eu spins are ferromagnetic. Thus we propose that EuNiGe3 has a collinear A-type antiferromagnetic structure, with the Eu ordered moments in the ab plane aligned ferromagnetically and with the moments in adjacent planes along the c axis aligned antiferromagnetically. A fit of chi(T <= T-N) by our molecular field theory is consistent with a collinear magnetic structure. Electrical resistivity rho data from T-N to 350 K are fitted by the Bloch-Gruneisen model for electron-phonon scattering, yielding a Debye temperature of 265(2) K. Astrong decrease in. occurs below T-N due to loss of spin-disorder scattering. Heat capacity data at 25 K <= T <= 300 K are fitted by the Debye model, yielding the same Debye temperature 268(2) K as found from rho(T). The extracted magnetic heat capacity is consistent with S = 7/2 and shows that significant short-range dynamical spin correlations occur above T-N. The magnetic entropy at T-N = 13.6 K is 83% of the expected asymptotic high-T value, with the remainder recovered by 30 K. DOI: 10.1103/PhysRevB.87.064406 C1 [Goetsch, R.

In the normal state, the imaginary part of the dynamic susceptibility, chi ''(Q,omega), shows magnetic anisotropy for energies below similar to 7 meV with c-axis polarized spin excitations larger than that of the in-plane component. Upon entering into the superconducting state, previous unpolarized INS experiments have shown that spin gaps at similar to 5 and 0.75 meV open at wave vectors Q = (0.5,0.5,0) and (0.5,0.5,1), respectively, with a broad neutron spin resonance at E-r = 15 meV. Our neutron polarization analysis reveals that the large difference in spin gaps is purely due to different spin gaps in the c axis and in-plane polarized spin excitations, resulting in a resonance with different energy widths for the c-axis and in-plane spin excitations. The observation of spin anisotropy in both optimally electron- and hole-doped BaFe2As2 is due to their proximity to the AF ordered BaFe2As2 where spin anisotropy exists below T-N.

Shannon's entropy is a measure for the amount of diversity present in any ensemble. In this work, Shannon's entropy of the SCFG ensemble on an RNA sequence is derived and implemented in polynomial time for both structurally ambiguous and unambiguous grammars. Micro RNA sequences generally have low folding entropy, as previously discovered. Surprisingly, signs of significantly high folding entropy were observed in certain ncRNA families. More effective models coupled with targeted randomization tests can lead to a better insight into folding features of these families. Availability: URL . (C) 2012 Elsevier Ltd. All rights reserved.

A simple approach to control the spatial organization of NP mixtures within supramolecular frameworks based on NP size has been developed. By varying the ratio of the NP size to the periodicity of the block-copolymer-based supramolecule, a range of hybrid NP assemblies in thin films, ranging from 1D chains to 2D lattices and 3D arrays and networks of NPs, can be readily generated.

We report the detailed structure of 2H-NbSe2 below the CDW transition using a (3 + 2)-dimensional crystallographic approach on single crystal X-ray diffraction data collected at 15 K. Intensities of main reflections as well as CDW satellites of first order were measured. Quantitative information about the magnitude of the structural distortions and clustering of Nb atoms were extracted from the refined model. The Nb-Nb distances were found to distort between 3.4102(8) and 3.4928(8) angstrom in the CDW phase from the average undistorted distance of 3.4583(4) angstrom.

Historically, spectroscopic analyses of the transition metal MO4x- anions have formed the basis for new M-O bonding theories. Herein, relative changes in M-O orbital mixing in MO42- (M = Cr, Mo, W) and MO4- (M = Mn, Tc, Re) are evaluated for the first time by nonresonant inelastic X-ray scattering, X-ray absorption spectroscopy using fluorescence and transmission (via a scanning transmission X-ray microscope), and time-dependent density functional theory. The results suggest that moving from Group 6 to Group 7 or down the triads increases M-O e* (pi*) mixing; for example, it more than doubles in ReO4- relative to CrO42-. Mixing in the t(2)* orbitals (sigma* + pi*) remains relatively constant within the same Group, but increases on moving from Group 6 to Group 7. These unexpected changes in orbital energy and composition for formally isoelectronic tetraoxometalates are evaluated in terms of periodic trends in d orbital energy and radial extension.

The results were compared with dilute sulfuric acid pretreatment at the same conditions. The maximum monomeric xylose yields were observed to be 93 and 94 wt % when CuCl2 and FeCl3 were used in the pretreatment at 160 degrees C for 10 min at 0.125 M concentrations, which were higher than the sulfuric acid pretreatment yields at the same reaction conditions. However, monomeric xylose yield for corn stover pretreated with AlCl3 was observed to be 8 wt % at the same condition. This could be explained by isomerization of xylose to xylulose and subsequent dehydration into furfural. However, enzymatic digestibility yields for the three metal chloride pretreated samples at 160 degrees C were greater than 92 wt %. These yields were higher than sulfuric acid pretreated samples at the same reaction conditions. The overall formation of fermentation inhibitor products for samples pretreated with CuCl2 and FeCl3 was observed to be similar to the control samples (pretreated with sulfuric acid at the same conditions).

TI Phase-Shift Method to Estimate Solids Circulation Rate in Circulating Fluidized Beds SO INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH LA English DT Article ID FLOW-RATE AB While solids circulation rate is a critical design and control parameter in circulating fluidized bed (CFB) reactor systems, there are no available techniques to measure it directly at conditions of industrial interest. Cold flow tests have been conducted at NETL in an industrial scale CFB unit where the solids flow has been the topic of research in order to develop an independent method which could be applied to CFBs operating under the erosive and corrosive high temperatures and pressures of a coal fired boiler or gasifier. The dynamic responses of the CFB loop to modest modulated aeration flows in the return leg or standpipe were imposed to establish a periodic response in the unit without causing upset in the process performance. The resulting periodic behavior could then be analyzed with a dynamic model and the average solids circulation rate could be established. This method was applied to the CFB unit operated under a wide range of operating conditions including fast fluidization, core annular flow, dilute and dense transport, and dense suspension upflow. In addition, the system was operated in both low and high total solids inventories to explore the influence of inventory limiting cases on the estimated results. The technique was able to estimate the solids circulation rate for all transport circulating fluidized beds when operating above upper transport velocity, U-tr2. For CFB operating in the fast fluidized bed regime (i.e., U-g < U-tr2), the phase shift technique was not successful. The riser pressure drop becomes independent of the solids circulation rate and the mass flow rate out of the riser does not show modulated behavior even when the riser pressure drop does.

We find a reversible pressure-induced tetragonal-to-orthorhombic structural transition at 5.5-6 GPa and reversible amorphization at 12-14 GPa. Two alternative structures are proposed for the high-pressure orthorhombic phase and are discussed in the context of a possible Au valence transition.

We emphasize the complementarity of these two particles in their production and decay to unambiguously determine their properties. We show that the Majorana nature of N can be verified by the lepton number violating like-sign dilepton process, and by polar and azimuthal angular distributions. The chirality of the W' coupling to leptons and to quarks can be determined by a polar angle distribution in the reconstructed frame and an azimuthal angle distribution.

The model is put to the test by comparing its predictions with the recent data from the D0 and TOTEM collaborations at 1.96 and 7 TeV, respectively. We also compare model predictions for inelastic cross sections to experimental measurements by the TOTEM, CMS, ALICE, and ATLAS collaborations. It is shown that the D0 data are perfectly predicted by the model. Total, elastic, and inelastic cross-section predictions are in agreement with the measurements by the TOTEM, CMS, ALICE, and ATLAS collaborations. Differential cross-section data at 7 TeV show slight disagreement with predictions of the model in the high-t region. Discussions on the origin of the disagreement and conclusions are presented.

Surprisingly, we find that the binding energy of both hole and electron bands changes significantly with temperature in both pure and Ru substituted samples. The hole and electron pockets are well nested at low temperature in unsubstituted (BaFe2As2) samples, which likely drives the spin density wave and resulting antiferromagnetic order. Upon warming, this nesting is degraded as the hole pocket shrinks and the electron pocket expands. Our results demonstrate that the temperature dependent nesting may play an important role in driving the antiferromagnetic-paramagnetic phase transition.

The low-energy effective Hamiltonians for such Mott insulators are derived in the presence of a strong spin-orbit coupling. These models are characterized by the antiferromagnetic Heisenberg interaction and the anisotropic interaction whose form depends on the d orbital occupancy. From exact diagonalization analyses on finite clusters, the ground state phase diagrams are derived, including a Kitaev spin liquid phase in a narrow parameter regime for t(2g) systems. Slave-boson mean-field analyses indicate the possibility of novel superconducting states induced by carrier doping into the Mott-insulating parent systems, suggesting the present model systems as unique playgrounds for studying correlation-induced novel phenomena. Possible experimental realizations are also discussed. DOI: 10.1103/PhysRevLett.110.066403 C1 Oak Ridge Natl Lab, Mat Sci & Technol Div, Oak Ridge, TN 37831 USA.

TI Oscillator seeding of a high gain harmonic generation free electron laser in a radiator-first configuration SO PHYSICAL REVIEW SPECIAL TOPICS-ACCELERATORS AND BEAMS LA English DT Article ID AMPLIFIED SPONTANEOUS-EMISSION; FEL; RADIATION; MODEL AB A longitudinally and transversely coherent, high repetition rate x-ray source with widely tunable wavelength is desired for a variety of experimental applications. A free electron laser (FEL) powered by an electron beam from a superconducting linac can reach the desired peak and average x-ray power levels with transverse coherence. However, generating longitudinally coherent x-ray pulses is a significant challenge, especially at high repetition rate. This paper presents a one-dimensional theoretical and numerical investigation of a method to achieve longitudinal coherence and high repetition rate simultaneously. We propose a "radiator-first" configuration, wherein an FEL oscillator follows a high gain harmonic generation (HGHG) FEL. The oscillator generates seed power that is directed upstream to initiate the HGHG process in a following electron bunch. This configuration allows for the generation of radiation at short wavelength, which is highly sensitive to energy spread, to occur before the longer wavelength oscillator, whose performance is not seriously degraded by the beam heating in the upstream radiator. The dynamics and stability of this radiator-first scheme is explored analytically and numerically. A single-pass, 1D map is derived using a semianalytic model for FEL gain and saturation. Iteration of the map is shown to be in good agreement with simulations. A numerical example is presented for a soft x-ray FEL. DOI: 10.1103/PhysRevSTAB.16.020703 C1 [Gandhi, P.; Wurtele, J.

When BaTiO3 underwent transitions from rhombohedral to orthorhombic to and from orthorhombic to tetragonal structures with increasing temperature, only local variations to the magnetic domains were observed. At the BaTiO3 tetragonal-cubic transition however, the magnetic domain size increased by 75% with an overall decrease in stray field contrast (33% decrease) because of reorientation of the magnetization to the in-plane directions. The reorientation of magnetization during the tetragonal to cubic phase transition of BaTiO3 was induced by release of asymmetric interfacial strain between the CoFe2O4 film and the BaTiO3 substrate, as non-uniformly distributed a and c surface ferroelectric domains in the BaTiO3 tetragonal phase disappeared at the paraelectric BaTiO3 cubic phase transition. Strain analysis based on macroscopic magnetization measurements was correlated with the microscopic magnetic domain structure to help understand the coupling in two-phase multiferroicheterostructure mediated by interfacial strain.

Further, the stability constant of the 1.Cs+ complex in FS 13 saturated with water was calculated for a temperature of 25 degrees C: log beta(org) (1.Cs+) = 9.9 +/- 0.1.

X-ray crystal structures of these compounds demonstrated that the coordination-driven self-assembly of copper(II) complexes with a tridentate ligand, 4'-Ph-trpy, connected by the 3- and 4-pyridinecarboxylate bridging ligands (nicotinate and iso-nicotinate respectively), have a pentacoordinate stereochemistry, which generates a regular square pyramid geometry. It is demonstrated that these geometrically controlled compounds generate two kinds of supramolecular architectures, mainly, those modulated by the pyridinecarboxylate ligand such as 1-D chains formed via intermolecular interactions with the iso-nicotinate ligand, and a 1-D coordination polymer when the nicotinate ligand is used.

TI Multimodel Predictive System for Carbon Dioxide Solubility in Saline Formation Waters SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID AQUEOUS NACL SOLUTIONS; EQUATION-OF-STATE; CO2 SOLUBILITY; GEOLOGICAL SEQUESTRATION; CUBIC EQUATION; IMPROVED MODEL; TREE ANALYSIS; PURE WATER; 100 MPA; CLASSIFICATION AB The prediction of carbon dioxide solubility in brine at conditions relevant to carbon sequestration (i.e., high temperature, pressure, and salt concentration (T-P-X)) is crucial when this technology is applied. Eleven mathematical models for predicting CO2 solubility in brine are compared and considered for inclusion in a multimodel predictive system. Model goodness of fit is evaluated over the temperature range 304-433 K, pressure range 74-500 bar, and salt concentration range 0-7 m (NaCl equivalent), using 173 published CO2 solubility measurements, particularly selected for those conditions. The performance of each model is assessed using various statistical methods, including the Akaike Information Criterion (AIC) and the Bayesian Information Criterion (BIC). Different models emerge as best fits for different subranges of the input conditions. A classification tree is generated using machine learning methods to predict the best-performing model under different T-P-X subranges, allowing development of a multimodel predictive system (MMoPS) that selects and applies the model expected to yield the most accurate CO2 solubility prediction. Statistical analysis of the MMoPS predictions, including a stratified 5-fold cross validation, shows that MMoPS outperforms each individual model and increases the overall accuracy of CO2 solubility prediction across the range of T-P-X conditions likely to be encountered in carbon sequestration applications.

TI Using Infrastructure Optimization to Reduce Greenhouse Gas Emissions from Oil Sands Extraction and Processing SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID CO2 CAPTURE; SEQUESTRATION SITE; SYSTEM MODEL; STORAGE; CARBON; UNCERTAINTY; CANADA; SAGD AB The Alberta oil sands are a significant source of oil production and greenhouse gas emissions, and their importance will grow as the region is poised for decades of growth. We present an integrated framework that simultaneously considers economic and engineering decisions for the capture, transport, and storage of oil sands CO2 emissions. The model optimizes CO2 management infrastructure at a variety of carbon prices for the oil sands industry. Our study reveals several key findings. We find that the oil sands industry lends itself well to development of CO2 trunk lines due to geographic coincidence of sources and sinks. This reduces the relative importance of transport costs compared to nonintegrated transport systems. Also, the amount of managed oil sands CO2 emissions, and therefore the CCS infrastructure, is very sensitive to the carbon price; significant capture and storage occurs only above 110$/tonne CO2 in our simulations. Deployment of infrastructure is also sensitive to CO2 capture decisions and technology, particularly the fraction of capturable CO2 from oil sands upgrading and steam generation facilities. The framework will help stakeholders and policy makers understand how CCS infrastructure, including an extensive pipeline system, can be safely and cost-effectively deployed.

TI Chemical and Mechanical Properties of Wellbore Cement Altered by CO2-Rich Brine Using a Multianalytical Approach SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID GEOLOGIC SEQUESTRATION CONDITIONS; CALCIUM SILICATE HYDRATE; AL-27 MAS NMR; CO2; SPECTROSCOPY; MINERALS; CONCRETE; KINETICS AB Defining chemical and mechanical alteration of wellbore cement by CO2-rich brines is important for predicting the long-term integrity of wellbores in geologic CO2 environments. We reacted CO2-rich brines along a cement-caprock boundary at 60 degrees C and pCO(2) = 3 MPa using flow-through experiments. The results show that distinct reaction zones form in response to reactions with the brine over the 8-day experiment. Detailed characterization of the crystalline and amorphous phases, and the solution chemistry show that the zones can be modeled as preferential portlandite dissolution in the depleted layer, concurrent calcium silicate hydrate (CSH) alteration to an amorphous zeolite and Ca-carbonate precipitation in the carbonate layer, and carbonate dissolution in the amorphous layer. Chemical reaction altered the mechanical properties of the core lowering the average Young's moduli in the depleted, carbonate, and amorphous layers to approximately 75, 64, and 34% of the unaltered cement, respectively. The decreased elastic modulus of the altered cement reflects an increase in pore space through mineral dissolution and different moduli of the reaction products.

A widely adopted model of a coupled oscillator network is characterized by a population of heterogeneous phase oscillators, a graph describing the interaction among them, and diffusive and sinusoidal coupling. It is known that a strongly coupled and sufficiently homogeneous network synchronizes, but the exact threshold from incoherence to synchrony is unknown. Here, we present a unique, concise, and closed-form condition for synchronization of the fully nonlinear, nonequilibrium, and dynamic network. Our synchronization condition can be stated elegantly in terms of the network topology and parameters or equivalently in terms of an intuitive, linear, and static auxiliary system. Our results significantly improve upon the existing conditions advocated thus far, they are provably exact for various interesting network topologies and parameters; they are statistically correct for almost all networks; and they can be applied equally to synchronization phenomena arising in physics and biology as well as in engineered oscillator networks, such as electrical power networks. We illustrate the validity, the accuracy, and the practical applicability of our results in complex network scenarios and in smart grid applications.

To uncover its in vivo functions in the retina, we generated a knockout mouse model, designated "miR-183C(GT/GT)," using a gene-trap embryonic stem cell clone. We provide evidence that inactivation of the cluster results in early-onset and progressive synaptic defects of the photoreceptors, leading to abnormalities of scotopic and photopic electroretinograms with decreased b-wave amplitude as the primary defect and progressive retinal degeneration. In addition, inactivation of the miR-183/96/182 cluster resulted in global changes in retinal gene expression, with enrichment of genes important for synaptogenesis, synaptic transmission, photoreceptor morphogenesis, and phototransduction, suggesting that the miR-183/96/182 cluster plays important roles in postnatal functional differentiation and synaptic connectivity of photoreceptors.

In situ measurements during deposition show that the source-drain current saturates rapidly after the percolation of monolayer-high islands, indicating that the electrical properties of ,-DH6T transistors are largely determined by the first molecular monolayer. The ,-DH6T monolayer consists of crystalline islands in which the long axes of molecules are oriented approximately perpendicular to the plane of the substrate surface. In-plane lattice constants measured using synchrotron grazing-incidence diffraction are larger in monolayer-thickness films than the in-plane lattice constants of several-monolayer films and of previously reported thick-film structures. Near-edge X-ray absorption fine structure spectroscopy (NEXAFS) reveals that the larger in-plane lattice constant of single-monolayer films arises from a larger tilt of the molecular axis away from the surface normal. NEXAFS spectra at the C 1s and S 2p edges are consistent with a high degree of molecular alignment and with the local symmetry imposed by the thiophene ring. The high mobility of holes in ,-DH6T monolayers can be attributed to the reduction of hole scattering associated with the isolation of the thiophene core from the interface by terminal hexyl chains.

From an analysis of the X-ray structure of the D96G/F171C/F219L triple mutant of bR and 60 independent molecular dynamics simulations of bR photointermediates, we report that the deprotonation of D96, a key residue in proton transfer reactions, serves two roles that occur sequentially. First, D96 donates a proton to the Schiff base. Subsequently, the deprotonation of D96 serves to "unlatch" the cytoplasmic side. The latching function of D96 appears to be remarkably robust, functioning to open hydration channels in all photointermediate structures. These results suggest that the protonation state of D96 may be the critical biophysical cue controlling the opening and closing of the cytoplasmic half-channel in bR. We suspect that this protonation-switch mechanism could also be utilized in other proton pumps to minimize backflow and reinforce directionality.

TI Nuclear Resonance Vibrational Spectroscopy and Electron Paramagnetic Resonance Spectroscopy of Fe-57-Enriched [FeFe] Hydrogenase Indicate Stepwise Assembly of the H-Cluster SO BIOCHEMISTRY LA English DT Article ID ACTIVE-SITE; CLOSTRIDIUM-PASTEURIANUM; DESULFOVIBRIO-DESULFURICANS; LIGHT SENSITIVITY; ONLY HYDROGENASE; H-2 PRODUCTION; IRON; SCATTERING; DYNAMICS; PROTEIN AB The [FeFe] hydrogenase from Clostridium pasteurianum (CpI) harbors four Fe-S clusters that facilitate the transfer of an electron to the H-duster, a ligand-coordinated six-iron prosthetic group that catalyzes the redox interconversion of protons and H-2. Here, we have used Fe-57 nuclear resonance vibrational spectroscopy (NRVS) to study the iron centers in CpI, and we compare our data to that for a [4Fe-4S] ferredoxin as well as a model complex resembling the [2Fe](H) catalytic domain of the H-cluster. To enrich the hydrogenase with Fe-57 nuclei, we used cell-free methods to post-translationally mature the enzyme. Specifically, inactive CpI apoprotein with Fe-56-labeled Fe-S clusters was activated in vitro using Fe-57-enriched maturation proteins. This approach enabled us to selectively label the [2Fe](H) subcluster with Fe-57, which NRVS confirms by detecting Fe-57-CO and Fe-57-CN normal modes from the H-cluster nonprotein ligands. The NRVS and iron quantification results also suggest that the hydrogenase contains a second Fe-57-S cluster. Electron paramagnetic resonance (EPR) spectroscopy indicates that this Fe-57-enriched metal center is not the [4Fe4S](H) subcluster of the H-duster. This finding demonstrates that the CpI hydrogenase retained an Fe-56-enriched [4Fe-4S](H) cluster during in vitro maturation, providing unambiguous evidence of stepwise assembly of the H-duster. In addition, this work represents the first NRVS characterization of [FeFe] hydrogenases. C1 [Kuchenreuther, Jon M.; Wang, Hongxin; Myers, William K.; George, Simon J.; Britt, R.

TI Taste of Sugar at the Membrane: Thermodynamics and Kinetics of the Interaction of a Disaccharide with Lipid Bilayers SO BIOPHYSICAL JOURNAL LA English DT Article ID FREE-ENERGY CALCULATIONS; COMPARATIVE MOLECULAR-DYNAMICS; WATER REPLACEMENT HYPOTHESIS; PHOSPHOLIPID-BILAYER; MONTE-CARLO; MYCOBACTERIUM-TUBERCULOSIS; FORCE-FIELD; CELL-WALL; TREHALOSE; LIPOARABINOMANNAN AB Sugar recognition at the membrane is critical in various physiological processes. Many aspects of sugar-membrane interaction are still unknown. We take an integrated approach by combining conventional molecular-dynamics simulations with enhanced sampling methods and analytical models to understand the thermodynamics and kinetics of a di-mannose molecule in a phospholipid bilayer system. We observe that di-mannose has a slight preference to localize at the water-phospholipid interface. Using umbrella sampling, we show the free energy bias for this preferred location to be just -0.42 kcal/mol, which explains the coexistence of attraction and exclusion mechanisms of sugar-membrane interaction. Accurate estimation of absolute entropy change of water molecules with a two-phase model indicates that the small energy bias is the result of a favorable entropy change of water molecules. Then, we incorporate results from molecular-dynamics simulation in two different ways to an analytical diffusion-reaction model to obtain association and dissociation constants for di-mannose interaction with membrane. Finally, we verify our approach by predicting concentration dependence of di-mannose recognition at the membrane that is consistent with experiment. In conclusion, we provide a combined approach for the thermodynamics and kinetics of a weak ligand-binding system, which has broad implications across many different fields.

TI Structure and Dynamics Studies of Concentrated Micrometer-Sized Colloidal Suspensions SO LANGMUIR LA English DT Article ID X-RAY-SCATTERING; PHOTON-CORRELATION SPECTROSCOPY; POLYSTYRENE LATEX SPHERES; NEAR-FIELD SPECKLE; BROWNIAN-MOTION; SLOW DYNAMICS; SOFT MATTER; DIFFRACTION; GLYCEROL AB We present an experimental study of the structural and dynamical properties of concentrated suspensions of different sized polystyrene microspheres dispersed in glycerol for volume fraction concentrations between 10% and 20%. The static structure, probed with ultrasmall-angle X-ray scattering, shows a behavior very similar to that of hard spheres. The equilibrium dynamics is probed with ultrasmall-angle X-ray scattering-X-ray photon correlation spectroscopy, a new technique that overcomes the limits of visible light-scattering techniques imposed by multiple scattering and is suitable for studies of optically opaque materials containing micrometer-sized structures. We found that the intensity autocorrelation functions are better described by a stretched exponential function and microspheres in a concentrated suspension move collectively. We also found that the inverse of the effective diffusion coefficients displays a peak with respect to the scattering vector that resembles the peaks in the static structure factors, which indicates that a long-lived, low free-energy state exists. The relaxation time is approximately inversely related to scattering vector, a behavior consistent with models that describe the dynamics in terms of random, local structural arrangements in disordered media.

TI Formation of Palladium Nanofilms Using Electrochemical Atomic Layer Deposition (E-ALD) with Chloride Complexation SO LANGMUIR LA English DT Article ID LIMITED REDOX REPLACEMENT; AU(111) ELECTRODE SURFACE; SINGLE-CRYSTAL SURFACES; EPITAXIAL-GROWTH; GALVANIC DISPLACEMENT; INITIAL-STAGES; PD DEPOSITION; THIN-FILMS; HYDROGEN; PLATINUM AB Pd thin films were formed by electrochemical atomic layer deposition (E-ALD) using surface-limited redox replacement (SLRR) of Cu underpotential deposits (UPD) on polycrystalline Au substrates. An automated electrochemical flow deposition system was used to deposit Pd atomic layers using a sequence of steps referred to as a cycle. The initial step was Cu UPD, followed by its exchange for Pd ions at open circuit, and finishing with a blank rinse to complete the cycle. Deposits were formed with up to 75 cycles and displayed proportional deposit thicknesses. Previous reports by this group indicated excess Pd deposition at the flow cell ingress, from electron probe microanalysis (EPMA). Those results suggested that the SLRR mechanism did not involve direct transfer between a Cu-UPD, atom and a Pd2+ ion that would take its position. Instead, it was proposed that electrons are transferred through the metallic surface to reduce Pd2+ ions near the surface where their activity is highest. It was proposed that if the cell was filled completely before a significant fraction of the Cu-UPD, atoms had been oxidized then the deposit would be homogeneous. Previous work with EDTA indicated that the hypothesis had merit, but it proved to be very sensitive to the EDTA concentration. In the present study, chloride was used to complex Pd2+ ions, forming PdCl42-, to slow the exchange rate. Both complexing agents led to a decrease in the rate of replacement, producing more homogeneous films. Although the use of EDTA improved the homogeneity, it also decreased the deposit thickness by a factor of 3 compared to the thickness obtained via the use of chloride.

TI Efficient carbon ion beam generation from laser-driven volume acceleration SO NEW JOURNAL OF PHYSICS LA English DT Article ID SOLIDS AB Experimental data on laser-driven carbon C6+ ion acceleration with a peak intensity of 5 x 10(20) W cm(-2) are presented and compared for opaque target normal sheath acceleration (TNSA) and relativistically transparent laser-plasma interactions. Particle numbers, peak ion energy and conversion efficiency have been investigated for target thicknesses from 50 nm to 25 mu m using unprecedented full spectral beam profile line-out measurements made using a novel high-resolution ion wide-angle spectrometer. For thicknesses of about 200 nm, particle numbers and peak energy increase to 5 x 10(11) carbon C6+ particles between 33 and 700 MeV (60 MeV u(-1)), which is a factor of five higher in particle number than that observed for targets with micron thickness. For 200 nm thick targets, we find that the peak conversion efficiency is 6% and that up to 55% of the target under the laser focal spot is accelerated to energies above 33 MeV. This contrasts with the results for targets with micron thickness, where surface acceleration with TNSA is dominant. The experimental findings are consistent with two-dimensional particle-in-cell simulations. C1 [Jung, D.; Yin, L.; Albright, B. J.; Gautier, D.

The two charged decay channels Lambda (1405) -> Sigma(+/-) + pi(-/+) have been reconstructed for the first time in p + p collisions. The efficiency and acceptance- corrected spectral shapes show a peak position clearly below 1400MeV/c(2). We find a total production cross section of sigma(Lambda(1405)) = (1405) = 9.2 +/- 0.9 +/- 0.7(-1.0)(+3.3)mu b . The analysis of its polar angle distribution suggests that the Lambda(1405) is produced isotropically in the p - p center-of-mass system (CMS).

The approximate symmetry decouples the dark matter mass from the confinement scale of the new gauge group, leading to correct thermal relic abundances for dark matter masses far below the unitary bound, avoiding the typical conclusion of thermally produced composite dark matter. We explore the available parameter space in a minimal example model based on an SU(2) gauge group, and discuss prospects for experimental detection.

While these measurements are not yet statistically significant enough to rule out the standard model, we demonstrate that the data from both experiments can be better fit with the inclusion of electroweak gauginos with masses of Omicron(100) GeV. We show that these gauginos are consistent with other searches or measurements and can have ramifications for Higgs phenomenology.

TI Accounting for baryons in cosmological constraints from cosmic shear SO PHYSICAL REVIEW D LA English DT Article ID MATTER POWER SPECTRUM; WEAK-LENSING SURVEYS; LARGE-SCALE STRUCTURE; DARK-MATTER; HALO CONCENTRATIONS; GALAXY GROUPS; TOMOGRAPHY; PHYSICS; STATISTICS; PARAMETERS AB One of the most pernicious theoretical systematics facing upcoming gravitational lensing surveys is the uncertainty introduced by the effects of baryons on the power spectrum of the convergence field. One method that has been proposed to account for these effects is to allow several additional parameters (that characterize dark matter halos) to vary and to fit lensing data to these halo parameters concurrently with the standard set of cosmological parameters. We test this method. In particular, we use this technique to model convergence power spectrum predictions from a set of cosmological simulations. We estimate biases in dark energy equation-of-state parameters that would be incurred if one were to fit the spectra predicted by the simulations either with no model for baryons or with the proposed method. We show that neglecting baryonic effect leads to biases in dark energy parameters that are several times the statistical errors for a survey like the Dark Energy Survey. The proposed method to correct for baryonic effects renders the residual biases in dark energy equation-of-state parameters smaller than the statistical errors. These results suggest that this mitigation method may be applied to analyze convergence spectra from a survey like the Dark Energy Survey. For significantly larger surveys, such as will be carried out by the Large Synoptic Survey Telescope, the biases introduced by baryonic effects are much more significant. We show that this mitigation technique significantly reduces the biases for such larger surveys, but that a more effective mitigation strategy will need to be developed in order ensure that the residual biases in these surveys fall below the statistical errors.

TI X-Ray Scattering Measurements of Strong Ion-Ion Correlations in Shock-Compressed Aluminum SO PHYSICAL REVIEW LETTERS LA English DT Article ID PLASMAS; CRYSTALS AB The strong ion-ion correlation peak characteristic of warm dense matter (WDM) is observed for the first time using simultaneous angularly, temporally, and spectrally resolved x-ray scattering measurements in laser-driven shock-compressed aluminum. Laser-produced molybdenum x-ray line emission at an energy of 17.9 keV is employed to probe aluminum compressed to a density of rho > 8 g/cm(3). We observe a well pronounced peak in the static structure factor at a wave number of k = 4.0 angstrom(-1). The measurements of the magnitude and position of this correlation peak are precise enough to test different theoretical models for the ion structure and show that only models taking the complex interaction in WDM into account agree with the data. This also demonstrates a new highly accurate diagnostic to directly measure the state of compression of warm dense matter.

NQEs strongly influence intramolecular properties, such as bond stability, and are thus an essential part of the dissociation process. Moreover, by including DFs that account for either the self-interaction error or dispersion interactions, we find a much better description of molecular dissociation and metallization than previous studies based on classical protons and/or local or semilocal DFs. We obtain excellent agreement with experimentally measured optical properties along Hugoniot curves for precompressed states, and while we still find a first-order liquid-liquid transition at low temperatures, transition pressures are increased by more than 100 GPa.

TI Role of Quantum Effects in the Glass Transition SO PHYSICAL REVIEW LETTERS LA English DT Article ID STRONG LIQUID TRANSITION; SUPERCOOLED CONFINED WATER; FORMING LIQUIDS; DYNAMICS; FRAGILITY; SPECTROSCOPY; RELAXATION; SCATTERING; SOLIDS AB It is shown that quantum effects lead to a significant decrease of the glass transition temperature T-g with respect to the melting temperature T-m, so that the ratio T-g/T-m can be much smaller than the typical value of 2/3 in materials where T-g is near or below similar to 60 K. Furthermore, it is demonstrated that the viscosity or structural relaxation time in such low temperature glass formers should exhibit highly unusual temperature dependence, namely a decrease of the apparent activation energy upon approaching T-g (instead of traditional increase).

Here we demonstrate that a quantum critical material, with a long-range mode that transmutes electrons between light and heavy bands, exhibits a quasilinear temperature dependence for both the single-particle and the charge transport lifetimes, despite the strong momentum dependence of the interaction.

TI Observation of Temperature-Induced Crossover to an Orbital-Selective Mott Phase in A(x)Fe(2-y)Se(2) (A = K, Rb) Superconductors SO PHYSICAL REVIEW LETTERS LA English DT Article ID ELECTRONIC-STRUCTURE; IRON PNICTIDES; MAGNETIC ORDER; INSULATOR; TRANSITION; ANISOTROPY AB Using angle-resolved photoemission spectroscopy, we observe the low-temperature state of the A(x)Fe(2-y)Se(2) (A = K, Rb) superconductors to exhibit an orbital-dependent renormalization of the bands near the Fermi level-the d(xy) bands heavily renormalized compared to the d(xz)/d(yz) bands. Upon raising the temperature to above 150 K, the system evolves into a state in which the d(xy) bands have depleted spectral weight while the d(xz)/d(yz) bands remain metallic. Combined with theoretical calculations, our observations can be consistently understood as a temperature-induced crossover from a metallic state at low temperatures to an orbital-selective Mott phase at high temperatures. Moreover, the fact that the superconducting state of A(x)Fe(2-y)Se(2) is near the boundary of such an orbital-selective Mott phase constrains the system to have sufficiently strong on-site Coulomb interactions and Hund's coupling, highlighting the nontrivial role of electron correlation in this family of iron-based superconductors.

TI Roughness analysis applied to niobium thin films grown on MgO(001) surfaces for superconducting radio frequency cavity applications SO PHYSICAL REVIEW SPECIAL TOPICS-ACCELERATORS AND BEAMS LA English DT Article ID DEPOSITION; ENHANCEMENT; FIELD; ZONE AB This paper describes surface studies to address roughness issues inherent to thin film coatings deposited onto superconducting radio frequency (SRF) cavities. This is particularly relevant for multilayered thin film coatings that are being considered as a possible scheme to overcome technical issues and to surpass the fundamental limit of similar to 50 MV/m accelerating gradient achievable with bulk niobium. In 2006, a model by Gurevich [Appl. Phys. Lett. 88, 012511 (2006)] was proposed to overcome this limit that involves coating superconducting layers separated by insulating ones onto the inner walls of the cavities. Thus, we have undertaken a systematic effort to understand the dynamic evolution of the Nb surface under specific deposition thin film conditions onto an insulating surface in order to explore the feasibility of the proposed model. We examine and compare the morphology from two distinct Nb/MgO series, each with its own epitaxial registry, at very low growth rates and closely examine the dynamical scaling of the surface features during growth. Further, we apply analysis techniques such as power spectral density to the specific problem of thin film growth and roughness evolution to qualify the set of deposition conditions that lead to successful SRF coatings.

TI Biocomposites of pHEMA with HA/beta-TCP (60/40) for bone tissue engineering: Swelling, hydrolytic degradation, and in vitro behavior SO POLYMER LA English DT Article DE pHEMA; Hydrolytic degradation; N,O-dimethactyloyl hydroxylamine ID OF-THE-ART; METHACRYLATE) HYDROGELS; POLY(ACRYLIC ACID); COMBINATORIAL; BIOMATERIALS; SCAFFOLDS; COMPOSITES; RELEASE; DRUGS; MINERALIZATION AB The field of bone and cartilage tissue engineering has a pressing need for novel, biocompatible, biodegradable biocomposites comprising polymers with bioceramics or bioglasses to meet numerous requirements for these applications. We created hydrolytically degradable hydrogel/bioceramic biocomposites, comprising poly(2-hydroxyethyl methacrylate) (pHEMA) hydrogels and 50 wt% biphasic hydroxyapatite/fi-tricalcium phosphate (60/40) through in situ polymerization. The hydrolytic degradation starts with hydrolysis of the cross-linker, N,O-dimethacryloyl hydroxylamine, which was synthesized in house. Swelling and degradation were examined in details at a phosphate buffered saline solution at 37 degrees C over a 12-week period of time. To vary degradability, a co-monomer, acrylic acid (AA) or 2-hydroxypropyl methacrylamide (HPMA), was introduced, coupled with altering the concentration of the cross-linker and of the bioceramic. The co-monomer HPMA was found to be more effective than AA in enhancing degradation, though AA led to greater swelling ratios. 33% of weight loss was achieved in some of the biocomposites containing HPMA. Porous structures were developed during swelling and degradation in biocomposites with AA but not in those containing HPMA, suggesting different degradation mechanisms: bulk erosion vs. bulk degradation. Good biocompatibility, as evidenced by attachment and proliferation of mouse-derived osteoblast precursor cells from the MC3T3-E1 lineage, was observed on these biomaterials, regardless of the type of the co-monomer. The rationale and approaches employed here open up new opportunities for creating novel, complex organic-inorganic biomaterials in orthopedic tissue engineering. (C) 2012 Elsevier Ltd.

All three viruses have slightly less than nine subunits per turn of the viral helix. Our data strongly support the view that all potexviruses have approximately the same symmetry. The structures are dominated by a large domain at high radius in the virion, with a smaller domain, which includes the putative RNA-binding site, extending to low radius. (C) 2012 Elsevier Inc.

We find strong evidence for a T-shape break-up pattern at a 5 eV excess energy as previously predicted by quasiclassical simulations [A. Emmanouilidou and J. M. Rost, J. Phys. B 39, 4037 (2006); A. Emmanouilidou, P. Wang, and J. M. Rost, Phys. Rev. Lett. 100, 063002 (2008)]. This finding is in conflict with the expected Wannier break-up dynamics of three electrons moving at mutual angles of 120 degrees, which is expected to hold at energies a few eV above threshold. We use our quantum- mechanical approach to explore the physical mechanisms behind this unusual break-up configuration.

Attracting their attention is the emergence of online social networks such as Twitter, as the information dissemination mechanism provided by these networks can naturally be exploited for spreading botnet C&C information, and the enormous amount of normal communications co-existing in these networks makes it a daunting task to tease out botnet C&C messages. Against this backdrop, we explore graph-theoretic techniques that aid effective monitoring of potential botnet activities in large open online social networks. Our work is based on extensive analysis of a Twitter dataset that contains more than 40 million users and 1.4 billion following relationships, and mine patterns from the Twitter network structure that can be leveraged for improving efficiency of botnet monitoring. Our analysis reveals that the static Twitter topology contains a small-sized core subgraph, after removing which, the Twitter network breaks down into small connected components, each of which can be handily monitored for potential botnet activities. Based on this observation, we propose a method called Peri-Watchdog, which computes the core of a large online social network and derives the set of nodes that are likely to pass botnet C&C information in the periphery of online social network. We analyze the time complexity of Peri-Watchdog under its normal operations. We further apply Peri-Watchdog on the Twitter graph injected with synthetic botnet structures and investigate the effectiveness of Peri-Watchdog in detecting potential C&C information from these botnets. To verify whether patterns observed from the static Twitter graph are common to other online social networks, we analyze another online social network dataset, BrightKite, which contains evolution of social graphs formed by its users in half a year. We show not only that there exists a similarly relatively small core in the BrightKite network, but also this core remains stable over the course of BrightKite evolution. We also find that to accommodate the dynamic growth of BrightKite, the core has to be updated about every 18 days under a constrained monitoring capacity. (c) 2012 Elsevier B.V. All rights reserved.

TI Effect of lithium borate addition on the physical and electrochemical properties of the lithium ion conductor Li3.4Si0.4P0.6O4 SO SOLID STATE IONICS LA English DT Article DE Lithium batteries; Ceramic lithium ion conductors; Li4SiO4-Li3PO4 solid solutions ID SECONDARY BATTERIES; SOLID ELECTROLYTES; GLASS-CERAMICS; AIR BATTERY; ORTHOSILICATE; SYSTEM AB The physical and electrochemical properties of a 60% Li3PO4-40% Li4SiO4 (60LP) solid solution phase have been investigated with the goal of developing an ion conductive protective layer for metallic lithium in secondary battery configurations. This phase was chosen because it has the highest ionic conductivity of 4 x 10(-6) S/cm at room temperature in the Li3PO4-Li4SiO4 solid solution series. Addition of 0.5 wt.% lithium borate or a mixture of its precursors lowered the sintering temperature of 60LP by as much as 150 degrees C without compromising the ionic conductivity of the dense pellets. Both AC and DC experiments showed that a stable interface is formed between the lithium and the phosphosilicate layer, allowing reversible lithium stripping and plating. The results are consistent with the assumption that the primary mobile species in the ceramic layer are lithium ions. (c) 2012 Elsevier B.V. All rights reserved.

TI Constitutive CCND1/CDK2 Activity Substitutes for p53 Loss, or MYC or Oncogenic RAS Expression in the Transformation of Human Mammary Epithelial Cells SO PLOS ONE LA English DT Article ID HUMAN BREAST-CANCER; CYCLIN D1; CELLULAR-TRANSFORMATION; INDUCED SENESCENCE; GROWTH; AMPLIFICATION; INACTIVATION; GENES; CDK2; PHOSPHORYLATION AB Cancer develops following the accumulation of genetic and epigenetic alterations that inactivate tumor suppressor genes and activate proto-oncogenes. Dysregulated cyclin-dependent kinase (CDK) activity has oncogenic potential in breast cancer due to its ability to inactivate key tumor suppressor networks and drive aberrant proliferation. Accumulation or over-expression of cyclin D1 (CCND1) occurs in a majority of breast cancers and over-expression of CCND1 leads to accumulation of activated CCND1/CDK2 complexes in breast cancer cells. We describe here the role of constitutively active CCND1/CDK2 complexes in human mammary epithelial cell (HMEC) transformation. A genetically-defined, stepwise HMEC transformation model was generated by inhibiting p16 and p53 with shRNA, and expressing exogenous MYC and mutant RAS. By replacing components of this model, we demonstrate that constitutive CCND1/CDK2 activity effectively confers anchorage independent growth by inhibiting p53 or replacing MYC or oncogenic RAS expression. These findings are consistent with several clinical observations of luminal breast cancer sub-types that show elevated CCND1 typically occurs in specimens that retain wild-type p53, do not amplify MYC, and contain no RAS mutations. Taken together, these data suggest that targeted inhibition of constitutive CCND1/CDK2 activity may enhance the effectiveness of current treatments for luminal breast cancer.

Its structure has been determined by single crystal X-ray diffraction using cocrystals obtained from either Ni-II(octaethylporphyrin) (Ni-II(OEP)) to form Sm@C-2v(3)-C-80 center dot Ni-II(OEP).1.68-(toluene).0.32(benzene) or bis(ethylenedithio)-tetrathiafulvalene (ET) to produce Sm@C-2v(3)-C-80.ET.0.5(toluene). Thus, this study offers the first opportunity to compare a common endohedral fullerene in two different cocrystals. Both cocrystals provide consistent information on the basic structure of SmgC(2v)(3)-C-80 but show that the distribution of samarium ion sites inside the carbon cage depends upon whether Ni-II(OEP) or ET is present. The samarium ion is disordered in both structures, but the prominent sites lie slightly off the 2-fold symmetry axis of the cage. Computational studies at the B3LYP level indicate that Sm@C-2v(3)-C-80 is more stable than any of the other six isomers of Sm@C-80 that obey the isolated pentagon rule (IPR). The surface electrostatic potential of the interacting components in the cocrystals has been examined to identify factors responsible for the ordering of the fullerene cages. The regions of the NiII(OEP) or ET molecules that are closest to the fullerene display negative potential, while the corresponding regions of the endohedral fullerene show positive potential in a consistent fashion in both cocrystals.

The structures of these gamma phases were solved in the acentric space group R3m (No. 160, Z = 6), and the observed lattice parameters from powder patterns were found to be a = 13.1029(6) and 13.1345(8) angstrom and c = 8.0410(4) and 8.1103(6) angstrom for crystals I and II, respectively. According to single-crystal refinements, the vacancies were found on the outer tetrahedron (OT) and octahedron (OH) of the 26-atom cluster. Single-crystal structural refinement clearly showed that the vacancy content per unit cell increases with increasing Zn, or valence-electron concentration. Electronic structure calculations, using the tight-binding linear muffin-tin orbital method with the atomic-sphere approximation (TB-LMTO-ASA) method, indicated the presence of a well-pronounced pseudogap at the Fermi level for "Au5Zn8" as the representative composition, an outcome that is consistent with the Hume-Rothery interpretation of gamma brass.

The metal-centered radical is monomeric under all conditions and exhibits Curie paramagnetic behavior in solution. An electrochemically reversible reduction to 18-electron CpCr(CO)(2)(IMe)(-) takes place at E-1/2 = 1.89(1) V vs Cp2Fe+./0 in MeCN, and was accomplished chemically with KC8 in tetrahydrofuran (THF). The salts K+(18-crown-6)[CpCr(CO)(2)( IMe)](-).1/ 2 T H F and K+ [CpCr-(CO)(2)(IMe)](-.3/4) THF were crystallographically characterized. Monomeric ion pairs are found in the former, whereas the latter has a polymeric structure because of a network of K center dot center dot center dot O-(CO) interactions. Protonation of K+(18-crown-6)[CpCr(CO)(2)(IMe)](-1/2) THF gives the hydride CpCr(CO)(2)(IMe)H, which could not be isolated, but was characterized in solution; a pK(a) of 27.2(4) was determined in MeCN. A thermochemical analysis provides the Cr-H bond dissociation free energy (BDFE) for CpCr(CO)(2)(IMe)H in MeCN solution as 47.3(6) kcal mori. This value is exceptionally low for a transition metal hydride, and implies that the reaction 2[Cr-H] -> 2[Cr] + H-2 is exergonic (triangle G = -9.0(8) kcal mol(-1)). This analysis explains the experimental observation that generated solutions of the hydride produce CpCr(CO)(2)(IMe)(center dot) (typically on the time scale of days). By contrast, CpCr(CO)(2)(PCy3)H has a higher Cr-H BDFE (52.9(4) kcal mol(-1)), is more stable with respect to H2 loss, and is isolable. C1 [van der Eide, Edwin F.; Helm, Monte L.; Bullock, R.

TI Electron transfer in hydrogenated nanocrystalline silicon observed by time-resolved terahertz spectroscopy SO PHYSICAL REVIEW B LA English DT Article ID AMORPHOUS-SILICON; SOLAR-CELLS; FRACTION; DEFECT; SI AB We report on the ultrafast carrier dynamics in hydrogenated nanocrystalline silicon (nc-Si: H) using time-resolved terahertz spectroscopy. Photoexcitation at 407 nm primarily produces charge carriers in the a-Si phase, but they undergo a rapid electron transfer to the c-Si phase prior to complete thermalization into the band-tail states of a-Si. We studied the carrier dynamics on a range of nc-Si: H samples with varying crystalline volume fractions (X-c) and mapped out the carrier dynamics with sub-ps resolution. Our measurements are consistent with a model in which electrons are first trapped at interface states at the a-Si-c-Si boundary prior to being thermally emitted into the c-Si phase. Wavelength and temperature dependent measurements are consistent with our model. The phenomena observed here have implications toward solar cell structures that utilize an amorphous material as an absorber layer, previously thought to have a mobility value too low to attain effective charge transport in a device.

CA ATLAS Collaboration TI Measurement of the Lambda(0)(b) lifetime and mass in the ATLAS experiment SO PHYSICAL REVIEW D LA English DT Article ID DECAYS AB A measurement of the Lambda(0)(b) lifetime and mass in the decay channel Lambda(0)(b) -> J/psi (mu(+) mu(-))Lambda(0)(p pi(-)) is presented. The analysis uses a signal sample of about 2200 Lambda(0)(b) and (Lambda) over bar (0)(b) decays that are reconstructed in 4.9 fb(-1) of ATLAS pp collision data collected in 2011 at the LHC center-of-mass energy of 7 TeV. A simultaneous mass and decay time maximum likelihood fit is used to extract the Lambda(0)(b) lifetime and mass. They are measured to be tau(Lambda b) = 1.449 +/- 0.036(stat) +/- 0.017(syst) ps and m(Lambda b) = 5619.7 +/- 0.7(stat) +/- 1.1(syst) MeV. DOI: 10.1103/PhysRevD.87.032002 C1 [Alam, M.

Xiao, Bo-Wen TI Universality of multiparticle production in QCD at high energies SO PHYSICAL REVIEW D LA English DT Article ID COLOR GLASS CONDENSATE; GLUON DISTRIBUTION; PA-COLLISIONS; LARGE NUCLEI; SMALL-X; EVOLUTION; QUARK AB By studying the color structure of multiparticle production processes in p + A-type (dilute-dense) collisions, we find that higher-point functions beyond typical dipoles and quadrupoles, e.g., sex tupoles, octupoles, etc., naturally appear in the cross sections, but are explicitly suppressed in the large-N-c limit. We evaluate the sextupole in the McLerran-Venugopalan model and find that, in general, its analytical form cannot be written as combination of dipoles and quadrupoles. Within the color glass condensate framework, we present a proof that in the large-N-c limit, all multiparticle production processes in the collision of a dilute system off a dense system can, up to all orders in alpha(s), be described in terms of only dipoles and quadrupoles.

Specifically, for these stars axion energy losses from the helium- burning core would shorten and eventually eliminate the blue loop phase of the evolution. This would contradict observational data, since the blue loops are required, e.g., to account for the existence of Cepheid stars. Using the MESA stellar evolution code, modified to include the extra cooling, we conservatively find g(A gamma gamma) <= 0.8 x 10(-10) GeV-1, which compares favorably with the existing bounds.

TI Full Electric Control of Exchange Bias SO PHYSICAL REVIEW LETTERS LA English DT Article ID MAGNETIC-ANISOTROPY; ROOM-TEMPERATURE; FILMS; BILAYERS AB We report the creation of a multiferroic field effect device with a BiFeO3 (BFO) (antiferromagnetic-ferroelectric) gate dielectric and a La0.7Sr0.3MnO3 (LSMO) (ferromagnetic) conducting channel that exhibits direct, bipolar electrical control of exchange bias. We show that exchange bias is reversibly switched between two stable states with opposite exchange bias polarities upon ferroelectric poling of the BFO. No field cooling, temperature cycling, or additional applied magnetic or electric field beyond the initial BFO polarization is needed for this bipolar modulation effect. Based on these results and the current understanding of exchange bias, we propose a model to explain the control of exchange bias. In this model the coupled antiferromagnetic-ferroelectric order in BFO along with the modulation of interfacial exchange interactions due to ionic displacement of Fe3+ in BFO relative to Mn3+/4- in LSMO cause bipolar modulation.

Laser sampling of current vs time delay between 12 keV x-ray and 800 nm laser pulses reveal the similar to 50 ps x-ray pulse width convoluted with the similar to 200 ps lifetime of the conduction band carriers. For GaAs implanted with 8 MeV protons, a time profile closer to the x-ray pulse width is observed. The protons create defects over the entire depth sampled by the x-rays, trapping the x-ray excited conduction electrons and minimizing lifetime broadening of the electrical excitation.

The screening affects the apparent STM height of each flake in successive layers reflecting the density of states near the Fermi level and thus the doping level. It is revealed in this way that the strong doping of the first graphene layer on Ru(0001) is attenuated in the second one, and almost eliminated in the third and fourth layers. Similar effect is also observed in graphene flakes on Cu(111). In contrast, the strong doping effect is suppressed immediately by a water layer intercalated between the graphene and Ru.

Ni particles were oxidized at temperatures between 400 and 850 degrees C in the TXM to directly observe their morphology change while the chemical composition is monitored by x-ray absorption near edge spectroscopy.

Two types of the devices, with and without a blocking layer for the IB, are prepared. The device with a blocked IB exhibits small external quantum efficiency (EQE) in photon energy range in which electron transitions from valence band (VB) to IB take place, implying the electron accumulation in IB.

TI Exact asymptotic behavior of magnetic stripe domain arrays SO PHYSICAL REVIEW B LA English DT Article ID 2-DIMENSIONAL ELECTRON LIQUID; INTERMEDIATE STATE; I SUPERCONDUCTORS; PATTERNS; SHAPES; FIELD AB The classical problem of magnetic stripe domain behavior in films and plates with uniaxial magnetic anisotropy is addressed. Exact analytical results are derived for the stripe domain widths as a function of applied perpendicular field H, in the regime where the domain period becomes large. The stripe period diverges as (H-c - H)(-1/2), where H-c is the critical (infinite period) field, an exact result confirming a previous conjecture. The magnetization approaches saturation as (H-c - H)(1/2), a behavior that compares excellently with experimental data obtained for a 4-mu m thick ferrite garnet film. The exact analytical solution provides a new basis for precise characterization of uniaxial magnetic films and plates, illustrated by a simple way to measure the domain wall energy. The mathematical approach is applicable for similar analysis of a wide class of systems with competing interactions where a stripe domain phase is formed.

TI Using the standard solar model to constrain solar composition and nuclear reaction S factors SO PHYSICAL REVIEW D LA English DT Article ID CHEMICAL-COMPOSITION; ABUNDANCE PROBLEM; NEUTRINO FLUXES; SUN; UNCERTAINTIES AB While standard solar model (SSM) predictions depend on approximately 20 input parameters, SSM neutrino flux predictions are strongly correlated with a single model output parameter, the core temperature T-c. Consequently, one can extract physics from solar neutrino flux measurements while minimizing the consequences of SSM uncertainties, by studying flux ratios with appropriate power-law weightings tuned to cancel this T-c dependence. We reexamine an idea for constraining the primordial C + N content of the solar core from a ratio of CN-cycle O-15 to pp-chain B-8 neutrino fluxes, showing that non-nuclear SSM uncertainties in the ratio are small and effectively governed by a single parameter, the diffusion coefficient. We point out that measurements of both CN-I cycle neutrino branches-O-15 and N-13 beta-decay-could, in principle, lead to separate determinations of the core C and N abundances, due to out-of-equilibrium CN-cycle burning in the cooler outer layers of the solar core. Finally, we show that the strategy of constructing "minimum uncertainty" neutrino flux ratios can also test other properties of the SSM. In particular, we demonstrate that a weighted ratio of Be-7 and B-8 fluxes constrains a product of S-factors to the same precision currently possible with laboratory data.

Airborne measurements of aerosol hygroscopicity are particularly challenging but critically needed. This motivated the development of a new system designed to measure the dependence of the aerosol light scattering coefficient (sigma(sp)) on relative humidity (RH), known as f(RH), in real-time on an aerial platform. The new instrument has several advantages over existing systems. It consists of three integrating nephelometers and humidity conditioners for simultaneous measurement of the sigma(sp) at three different RHs. The humidity is directly controlled in exchanger cells without significant temperature disturbances and without particle dilution, heating, or loss of volatile compounds. The single-wavelength nephelometers are illuminated by LED-based light sources thereby minimizing heating of the sample stream. The flexible design of the RH conditioners, consisting of a number of specially designed exchanger cells (driers or humidifiers), enables us to measure f(RH) under hydration or dehydration conditions (always starting with the aerosol in a known state) with a simple system reconfiguration. These exchanger cells have been characterized for losses of particles using latex spheres and laboratory generated ammonium sulfate aerosols. The performance of this instrument has been assessed aboard DOE's G-1 research aircraft during test flights over California, Oregon, and Washington. C1 [Pekour, M.

Pulsations levitate material from the stellar surface and provide density enhancements and shocks, which can encourage dust formation and re-processing. The dust composition depends on the atmospheric chemistry (abundance of carbon relative to oxygen), which is altered by dredging up newly formed carbon to the surface of the star. I will briefly review the current status of models that include AGB mass loss and relate them to recent observations of AGB stars from the Surveying the Agents of Galaxy Evolution (SAGE) Spitzer surveys of the Small and Large Magellanic Clouds, including measures of the total dust input to the interstellar medium from AGB stars.

Many new biological insights can be expected from a better understanding of the processes that occur on these very fast and very small scales. In this regard, new instruments that use fast X-ray or electron pulses are expected to reveal novel mechanistic details for macromolecular protein dynamics. To ensure that any observed conformational change is physiologically relevant and not constrained by 3D crystal packing, it would be preferable for experiments to utilize small protein samples such as single particles or 2D crystals that mimic the target protein's native environment. These samples are not typically amenable to X-ray analysis, but transmission electron microscopy has imaged such sample geometries for over 40 years using both direct imaging and diffraction modes. While conventional transmission electron microscopes (TEM) have visualized biological samples with atomic resolution in an arrested or frozen state, the recent development of the dynamic TEM (DTEM) extends electron microscopy into a dynamic regime using pump-probe imaging. A new second-generation DTEM, which is currently being constructed, has the potential to observe live biological processes with unprecedented spatio-temporal resolution by using pulsed electron packets to probe the sample on micro-and nanosecond timescales. This article reviews the experimental parameters necessary for coupling DTEM with in situ liquid microscopy to enable direct imaging of protein conformational dynamics in a fully hydrated environment and visualize reactions propagating in real time.

Given load curves for energy services requirements in a building microgrid (mu center dot grid), fuel costs and other economic inputs, and a menu of available technologies, the model finds the optimum equipment fleet and operating schedule. This capability is being applied using a Software as a Service (SaaS) model. The evolution of this approach is demonstrated by description of four past and present projects: (1) a public access web site focused on solar photovoltaic generation and battery viability for large non-residential customers; (2) a building CO2 emissions reduction operations problem for a university dining hall with potential investments considered; (3) a battery and rolling operating schedule problem for a large county jail; and (4) the direct control of the solar-assisted heating ventilation and air conditioning system of a university building by providing optimised daily schedules that are automatically implemented in the building's energy management and control system. Together these examples show that optimisation of building grid design and operation can be effectively achieved using SaaS.

Knowing these mediating processes is critical to understanding the links between genes and behavior and how these factors differ between people. We identified and characterized the effects of a gene on neurochemistry and neural networks to elucidate the mechanism, at the systems level, whereby genes influence cognition. Catechol-O-methyltransferase (COMT) degrades dopamine in the prefrontal cortex (PFC) and is polymorphic with alleles differing in enzymatic activity. We found that COMT genotype determined dopamine synthesis, such that individuals with greater COMT activity synthesized more dopamine. Dopamine synthesis in the midbrain and ventral striatum affected functional connectivity in the default mode network, likely through the mesocorticolimbic pathway, in an inverted-U pattern with greater functional connectivity in medial PFC associated with intermediate levels of COMT activity and dopamine. Greater functional connectivity correlated with greater deactivation during performance of a set-shifting task that engaged the PFC. Greater deactivation was in turn associated with better performance. The integration of these results yields a model whereby COMT affects prefrontal function by a mechanism involving dopaminergic modulation of the default mode network. The model features the well-known inverted-U function between dopamine and performance and supports the hypothesis that dopamine and the default mode network shift attentional resources to influence prefrontal cognition.

To test the hypothesis that crosstalk between the liver and pancreatic islets modulates beta cell growth in response to insulin resistance, we used the liver-specific insulin receptor knockout (LIRKO) mouse, a unique model that exhibits dramatic islet hyperplasia. Using complementary in vivo parabiosis and transplantation assays, as well as in vitro islet culture approaches, we demonstrate that humoral, nonneural, non-cell-autonomous factor(s) induces beta cell proliferation in LIRKO mice. Furthermore, we report that a hepatocyte-derived factor(s) stimulates mouse and human beta cell proliferation in ex vivo assays, independent of ambient glucose and insulin levels. These data implicate the liver as a critical source of beta cell growth factor(s) in insulin-resistant states.

We built a regulatory map for 24 NRs, six chromatin state markers, and 14 breast-cancer-associated transcription factors (TFs) that are expressed in the breast cancer cell line MCF-7. The resulting network reveals a highly interconnected regulatory matrix where extensive crosstalk occurs among NRs and other breast -cancer-associated TFs. We show that large numbers of factors are coordinately bound to highly occupied target regions throughout the genome, and these regions are associated with active chromatin state and hormone-responsive gene expression. This network also provides a framework for stratifying and predicting patient outcomes, and we use it to show that the peroxisome proliferator-activated receptor delta binds to a set of genes also regulated by the retinoic acid receptors and whose expression is associated with poor prognosis in breast cancer.

TI Viral Escape from Neutralizing Antibodies in Early Subtype A HIV-1 Infection Drives an Increase in Autologous Neutralization Breadth SO PLOS PATHOGENS LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-1; MONOCLONAL-ANTIBODIES; STRUCTURAL BASIS; C INFECTION; ENVELOPE GLYCOPROTEINS; POTENT NEUTRALIZATION; RATIONAL DESIGN; BINDING-SITE; ENV CLONES; V3 DOMAIN AB Antibodies that neutralize (nAbs) genetically diverse HIV-1 strains have been recovered from a subset of HIV-1 infected subjects during chronic infection. Exact mechanisms that expand the otherwise narrow neutralization capacity observed during early infection are, however, currently undefined. Here we characterized the earliest nAb responses in a subtype A HIV-1 infected Rwandan seroconverter who later developed moderate cross-clade nAb breadth, using (i) envelope (Env) glycoproteins from the transmitted/founder virus and twenty longitudinal nAb escape variants, (ii) longitudinal autologous plasma, and (iii) autologous monoclonal antibodies (mAbs). Initially, nAbs targeted a single region of gp120, which flanked the V3 domain and involved the alpha2 helix. A single amino acid change at one of three positions in this region conferred early escape. One immunoglobulin heavy chain and two light chains recovered from autologous B cells comprised two mAbs, 19.3H-L1 and 19.3H-L3, which neutralized the founder Env along with one or three of the early escape variants carrying these mutations, respectively. Neither mAb neutralized later nAb escape or heterologous Envs. Crystal structures of the antigen-binding fragments (Fabs) revealed flat epitope contact surfaces, where minimal light chain mutation in 19.3H-L3 allowed for additional antigenic interactions. Resistance to mAb neutralization arose in later Envs through alteration of two glycans spatially adjacent to the initial escape signatures. The cross-neutralizing nAbs that ultimately developed failed to target any of the defined V3-proximal changes generated during the first year of infection in this subject. Our data demonstrate that this subject's first recognized nAb epitope elicited strain-specific mAbs, which incrementally acquired autologous breadth, and directed later B cell responses to target distinct portions of Env. This immune re-focusing could have triggered the evolution of cross-clade antibodies and suggests that exposure to a specific sequence of immune escape variants might promote broad humoral responses during HIV-1 infection.

For simulators with multivariate output, common practice is to specify a separable covariance structure for the Gaussian process. Though computationally convenient, this can be too restrictive, leading to poor performance of the emulator, particularly when the different simulator outputs represent different physical quantities. Also, treating the simulator outputs as independent can lead to inappropriate representations of joint uncertainty. We develop nonseparable covariance structures for Gaussian process emulators, based on the linear model of coregionalization and convolution methods. Using two case studies, we compare the performance of these covariance structures both with standard separable covariance structures and with emulators that assume independence between the outputs. In each case study, we find that only emulators with nonseparable covariances structures have sufficient flexibility both to give good predictions and to represent joint uncertainty about the simulator outputs appropriately.

In this article, we develop a GP-based inverse method that allows for the direct estimation of the derivative of a one-dimensional curve. In principle, a GP model may be fit to the data directly, with the derivatives obtained by means of differentiation of the correlation function. However, it is known that this approach can be inadequate due to loss of information when differentiating. We present a new method of obtaining the derivative process by viewing this procedure as an inverse problem. We use the properties of a GP to obtain a computationally efficient fit. We illustrate our method with simulated data as well as apply it to an important cosmological application. We include a discussion on model comparison techniques for assessing the quality of the fit of this alternative method. Supplementary materials for this article are available online.

TI Global Sensitivity Analysis for Mixture Experiments SO TECHNOMETRICS LA English DT Article DE Computer experiment; Gaussian process; Mixture experiment; Simplex designs; Visualization ID COMPUTER EXPERIMENTS; CALIBRATION; PREDICTION; SIMPLEX; DESIGNS; MODELS AB A mixture experiment is characterized by having two or more inputs that are specified as a percentage contribution to a total amount of material. In such situations, the input variables are correlated because they must sum to one. Consequently, additional care must be taken when fitting statistical models or visualizing the effect of one or more inputs on the response. In this article, we consider the use of a Gaussian process to model the output from a computer simulator taking a mixture input. We introduce a procedure to perform global sensitivity analysis of the code output providing main effects and revealing interactions. The resulting methodology is illustrated using a function with analytically tractable results for comparison, a chemical compositional simulator, and a physical experiment.

In particular, the Majorana neutrino mass matrix includes contributions from an A(4) triplet, 1, 1', and 1 '' flavon fields. Using these formulae, we constrain the general A(4) parameter space using the updated global fits on neutrino mixing angles and mass squared differences, including results from the Daya Bay and RENO experiments, and we find predictive relations among the mixing parameters for certain choices of the triplet vacuum expectation value. In the normal hierarchy case, sizable deviation from maximal atmospheric mixing is predicted, and such deviation is strongly correlated with the value of theta(13) in the range of similar to(8 - 10)degrees. On the other hand, such deviation is negligible and insensitive to theta(13) in the inverted mass hierarchy case. We also show expectations for the Dirac CP phase resulting from the parameter scan. Future refined measurements of neutrino mixing angles will test these predicted correlations and potentially show evidence for particular triplet vev patterns.

Here, we report the measurement of optical transition radiation (OTR) from the capillary-based LPA electron beams. Transition radiation images, produced by electrons passing through two separate foils (located at 2.3 m and 3.8 m away from the exit of the LPA) were recorded with a high resolution imaging system, respectively. Two magnetic quadrupole lenses were placed right after the capillary to focus and collimate the electron beams. Significant localized spikes appeared in the OTR images when the electron beam was focused by the magnetic quadrupole lenses, indicating the coherence of the radiation and the existence of ultrashort longitudinal structures inside the electron beam.

TI WEATHERING OF ALMANDINE GARNET: INFLUENCE OF SECONDARY MINERALS ON THE RATE-DETERMINING STEP, AND IMPLICATIONS FOR REGOLITH-SCALE Al MOBILIZATION SO CLAYS AND CLAY MINERALS LA English DT Article DE Almandine Garnet; Chemical Weathering; Coweeta Hydrologic Laboratory; Gibbsite; Goethite; Hematite; Kaolinite; Protective Surface Layers; Saprolite; Unprotective Surface Layers ID BLUE RIDGE FRONT; ROCK-FORMING MINERALS; SOIL-GEOMORPHIC RELATIONS; IRON-BEARING MINERALS; NORTH-CAROLINA; ETCH PITS; LONG-TERM; DISSOLUTION; MECHANISM; SAPROLITE AB Secondary surface layers form by replacement of almandine garnet during chemical weathering. This study tested the hypothesis that the kinetic role of almandine's weathering products, and the consequent relationships of primary-mineral surface texture and specific assemblages of secondary minerals, both vary with the solid-solution-controlled variations in Fe and Al contents of the specific almandine experiencing weathering. Surface layers are protective (PSL) when the volume of the products formed by replacement is greater than or equal to the volume of the reactants replaced. Under such circumstances, reaction kinetics at the interface between the garnet and the replacing mineral are transport controlled and either transport of solvents or other reactants to, or products from, the dissolving mineral is rate limiting. Beneath PSLs, almandine garnet surfaces are smooth, rounded, and featureless. Surface layers are unprotective (USL) when the volume of the products formed by replacement is less than the volume of the reactants replaced. Under such circumstances, reaction kinetics at the interface between the garnet and the replacing mineral are interface controlled and the detachment of ions or molecules from the mineral surface is rate limiting. Almandine garnet surfaces beneath USLs exhibit crystallographically oriented etch pits. However, contrary to expectations, etch pits occur on almandine garnet grains beneath some layers consisting of mineral assemblages consistent with PSLs. Based on the Pilling-Bedworth criterion, surface layers are more likely to be protective over a broad range of reactant-mineral compositions when they contain goethite, kaolinite, and pyrolusite. However, this combination requires specific ranges of Fe and Al content of the natural reacting almandine garnet. To form a PSL of goethite and kaolinite, an almandine garnet must have a minimum Al stoichiometric coefficient of similar to 3.75 a.p.f.u., and a minimum Fe stoichiometric coefficient of similar to 2.7 a.p.f.u. Product minerals also influence the mobility of the least-mobile major rock-forming elements. A PSL consisting of goethite, gibbsite, and kaolinite yields excess Al for export during almandine garnet weathering. As the quantity of kaolinite present in the PSL decreases, the amounts of Al available for export increases.

It was observed that water contact angles on treated substrates decreased as laser power increased. Nanometer-scale gold coating on the surfaces allowed the effect of change in morphology on wettability to be quantified independently from the effect of chemistry change. Morphology change and chemistry change were both found to have independent hydrophilic effects on the surface wettability change that increased with laser power. As laser power increased, the treated sample surface transitioned from a rough fibrous mesh to more as a porous flat film. A laser power of 4.5mW was found to divide both the surface morphology change and morphology-induced wettability change into high-power and low-power regimes. The Cassie-Baxter model successfully predicted the wettability of gold-coated surfaces using measured characteristics of surfaces from both regimes. All the laser-treated and untreated surfaces investigated in this work exhibited robust hydrophobic behavior. (C) 2013 Laser Institute of America.

This article aims to identify important charged species and their temporal variation in a spark-ignited methane/air mixture using the equilibrium constant method. The equilibrium composition of 20 neutral and seven charged species [(e), CHO+, H3O+, NO+, OH, , O] was obtained using a novel adaptation of the NewtonRaphson method for highly stiff nonlinear system of equations. A two-zone combustion model was used to study the effect of airfuel ratio (AFR) on the temporal variation of charged species concentration. Temporal variation of the current computed from the equilibrium concentration of charged species was found to compare well with experimental data for several AFRs.

Although such solar cells are expected to be more expensive there are growing needs for the efficient and light-weight solar cells in aero-space and related industries. In this paper I present the theoretical, and computational investigation of novel designs for quantum dot superlattice (QDS) based PV cells. I describe possible implementations of the intermediate-band (IB) solar cells with QDS. The IB cells are predicted to have PV efficiency exceeding the Shockley-Queisser limit of a single junction cell. The parameters of QDS structures are tuned to achieve a desired charge carrier dispersion required for the IB operation. The first-principles models are used to calculate the electrical properties and light absorption in QDS. This approach allows for determination of the dimensions of QDS for forming the mini-band which plays the role of the IB. Using the detailed balance theory it is determined that the upper-bound PV efficiency of such IB solar cells can be as high as 51%. The required QDS dimensions on the basis of InAsN/GaAsSb are technologically challenging but feasible: 2-6 nm. Using the developed simulation tools several possible designs of QDS based solar cells are proposed. C1 Lawrence Livermore Natl Lab, Ctr Micro & Nano Technol, Livermore, CA 94550 USA.

Historically, wind turbines are placed on Earth's surface, but high-altitude winds are usually steadier and faster than near-surface-winds, resulting in higher average power densities(1). Here, we use a climate model to estimate the amount of power that can be extracted from both surface and high-altitude winds, considering only geophysical limits. We find wind turbines placed on Earth's surface could extract kinetic energy at a rate of at least 400 TW, whereas high-altitude wind power could extract more than 1,800 TW. At these high rates of extraction, there are pronounced climatic consequences. However, we find that at the level of present global primary power demand (similar to 18 TW; ref. 2), uniformly distributed wind turbines are unlikely to substantially affect the Earth's climate. It is likely that wind power growth will be limited by economic or environmental factors, not global geophysical limits.

The main new result is our demonstration of how to use a behavior's or process' k-order statistics to build a stochastic process that has the same k-order stationary statistics but possesses different, deliberately designed, (k + 1)-order statistics if desired. Such a model realizes a "complexification" of the process or behavior which a defender can use to monitor whether an attacker is shaping the behavior. We also describe a source coding technique that respects the -order statistics, including entropy which is a first order statistic for example, of a process while encoding information covertly, and we show how to achieve optimizing information rates. Although the main results and examples are stated in terms of behavioral anomaly detection for covert channels, the techniques are more generally applicable to behavioral anomaly analysis. One fundamental consequence of these results is that certain types of behavioral anomaly detection techniques come down to an arms race in the sense that the advantage goes to the party that has more computing resources applied to the problem.

Sun, Jiwei Wang, Pingshan TI Coplanar Waveguides With Nanometer Thick Gold Films SO IEEE MICROWAVE AND WIRELESS COMPONENTS LETTERS LA English DT Article DE Coplanar waveguide (CPW); percolation theory; thin film; transmission lines ID CONDUCTIVITY; CLUSTERS AB Coplanar waveguides (CPWs) with 8 nm to 50 nm thick gold films are fabricated and characterized up to 40 GHz. Such film thicknesses are comparable with or thinner than electron mean-free-path (MFP) in gold. In this size effect regime, skin effect is negligible. The measured results show that the CPWs have less dispersion, but higher loss when compared with thick metal CPWs. A thin film resistivity model, which includes the effects of electron scatterings from metal surfaces, grain boundaries and surface roughness, is proposed to describe the microwave resistance of such CPWs. For an 8 nm CPW, it has much higher resistance and inductance given that 8 nm is around the percolation threshold of gold films. Furthermore, its inductance and resistance decrease with frequencies due to enhanced coupling among metallic islands. The quality factors of nanometer-CPWs are low, especially at low frequencies. Nevertheless, these CPWs have potential applications in local and regional interconnect, biomedical sensors, microwave nanofluidic channels, and disordered-electronic-system studies. Further work is needed to understand and accurately model nanometer CPWs. C1 [Wang, Shenghan; Sun, Jiwei; Wang, Pingshan] Clemson Univ, Dept Elect & Comp Engn, Clemson, SC 29634 USA.

We describe the sample selection, basic properties of the galaxies and caveats for working with the data. We calculate the real-and redshift-space two-point correlation functions of these galaxies, fit these measurements using halo occupation distribution (HOD) modelling within dark matter cosmological simulations, and estimate the errors using mock catalogues. These galaxies lie in massive haloes, with a mean halo mass of 5.2 x 10(13) h(-1) M-circle dot, a large-scale bias of similar to 2.0 and a satellite fraction of 12 +/- 2 per cent. Thus, these galaxies occupy haloes with average masses in between those of the higher redshift BOSS CMASS sample and the original SDSS I/II luminous red galaxy sample.

CA ATLAS Collaboration TI Measurement of the flavour composition of dijet events in pp collisions at root s=7 TeV with the ATLAS detector SO EUROPEAN PHYSICAL JOURNAL C LA English DT Article ID CROSS-SECTION; PARTON DISTRIBUTIONS; COLLIDER AB This paper describes a measurement of the flavour composition of dijet events produced in pp collisions at root s = 7 TeV using the ATLAS detector. The measurement uses the full 2010 data sample, corresponding to an integrated luminosity of 39 pb(-1). Six possible combinations of light, charm and bottom jets are identified in the dijet events, where the jet flavour is defined by the presence of bottom, charm or solely light flavour hadrons in the jet. Kinematic variables, based on the properties of displaced decay vertices and optimised for jet flavour identification, are used in a multidimensional template fit to measure the fractions of these dijet flavour states as functions of the leading jet transverse momentum in the range 40 GeV to 500 GeV and jet rapidity vertical bar y vertical bar < 2.1. The fit results agree with the predictions of leading-and next-to-leading-order calculations, with the exception of the dijet fraction composed of bottom and light flavour jets, which is underestimated by all models at large transverse jet momenta. The ability to identify jets containing two b-hadrons, originating from e. g. gluon splitting, is demonstrated. The difference between bottom jet production rates in leading and subleading jets is consistent with the next-to-leading-order predictions.

CA H1 Collaboration ZEUS Collaboration TI Combination and QCD analysis of charm production cross section measurements in deep-inelastic ep scattering at HERA SO EUROPEAN PHYSICAL JOURNAL C LA English DT Article ID D-ASTERISK(+/-) MESON PRODUCTION; 3-LOOP SPLITTING FUNCTIONS; HEAVY FLAVOR PRODUCTION; H1 VERTEX DETECTOR; GREATER-THAN M(2); PARTON DISTRIBUTIONS; D-ASTERISK; INCLUSIVE DISTRIBUTIONS; O(ALPHA-S) CORRECTIONS; LEADING ORDER AB Measurements of open charm production cross sections in deep-inelastic ep scattering at HERA from the H1 and ZEUS Collaborations are combined. Reduced cross sections sigma(c (c) over bar)(red) for charm production are obtained in the kinematic range of photon virtuality 2.5 <= Q(2) <= 2000 GeV2 and Bjorken scaling variable 3 . 10(-5) <= x <= 5 . 10(-2). The combination method accounts for the correlations of the systematic uncertainties among the different data sets. The combined charm data together with the combined inclusive deep-inelastic scattering cross sections from HERA are used as input for a detailed NLO QCD analysis to study the influence of different heavy flavour schemes on the parton distribution functions. The optimal values of the charm mass as a parameter in these different schemes are obtained. The implications on the NLO predictions for W-+/- and Z production cross sections at the LHC are investigated. Using the fixed flavour number scheme, the running mass of the charm quark is determined. C1 [Aggarwal, R.; Kaur, P.; Martyn, H. -U.] Rhein Westfal TH Aachen, Inst Phys 1, Aachen, Germany.

TI Explaining the Higgs decays at the LHC with an extended electroweak model SO EUROPEAN PHYSICAL JOURNAL C LA English DT Article ID DILEPTON GAUGE BOSONS; FUTURE-PROSPECTS; STANDARD MODEL; BILEPTONS; MASS; COLLISIONS; LEPTONS; BOUNDS; SCALE AB We show that the observed enhancement in the diphoton decays of the recently discovered new boson at the LHC, which we assume to be a Higgs boson, can be naturally explained by a new doublet of charged vector bosons from extended electroweak models with SU(3)(C) circle times SU(3)(L) circle times U(1)(X) symmetry. These models are also rather economical in explaining the measured signal strengths, within the current experimental errors, demanding fewer assumptions and less parameters tuning. Our results show a good agreement between the theoretical expected sensitivity to a 126-125 GeV Higgs boson, and the experimental significance observed in the diphoton channel at the 8 TeV LHC. Effects of an invisible decay channel for the Higgs boson are also taken into account, in order to anticipate a possible confirmation of deficits in the branching ratios into ZZ*, WW*, bottom quarks, and tau leptons.

This contour deformation can be used to perform the integration for multi-loop integrals numerically. The integration can be performed directly in loop momentum space without the introduction of Feynman or Schwinger parameters. The method can be applied to finite multi-loop integrals and to divergent multi-loop integrals with suitable subtraction terms. The algorithm extends techniques from the one-loop case to the multi-loop case. Examples at two and three loops are discussed explicitly.

CA CMS Collaboration TI Measurement of the sum of WW and WZ production with W plus dijet events in pp collisions at root s=7 TeV SO EUROPEAN PHYSICAL JOURNAL C LA English DT Article ID GAUGE-BOSON COUPLINGS; SEARCH; LIMITS; LEP AB A measurement of the inclusive WW+WZ diboson production cross section in proton-proton collisions is reported, based on events containing a leptonically decaying W boson and exactly two jets. The data sample, collected at root s = 7 TeV with the CMS detector at the LHC, corresponds to an integrated luminosity of 5.0 fb(-1). The measured value of the sum of the inclusive WW and WZ cross sections is sigma(pp -> WW + WZ) = 68.9 +/- 8.7 (stat.) +/- 9.7 (syst.) +/- 1.5 (lum.) pb, consistent with the standard model prediction of 65.6 +/- 2.2 pb. This is the first measurement of WW+WZ production in pp collisions using this signature. No evidence for anomalous triple gauge couplings is found and upper limits are set on their magnitudes.

It is revealed that the composition gradient sputtering method dramatically improves the high-frequency soft magnetic properties of the as-prepared films. This method gives rise to almost a linearly-increased distribution of compositions and residual stress. As a result, a very high ferromagnetic resonance frequency up to 6.7 GHz, high uniaxial magnetic anisotropic field up to 450 Oe, and low magnetic loss were obtained in as-deposited samples, which are particularly in favor of the integration between magnetic films and microwave components.

It is revealed that this multiferroic heterostructure shows very strong magnetoelectric coupling, leading to continuously tunable microwave frequency characteristics by electric field. With the increase of electric field intensity from 0 to 6 kV/cm, the magnetic anisotropy field H-K increases from 90 Oe to 182 Oe with an increment of 102%, corresponding to a ME coefficient of 15.3 Oe cm/kV; the ferromagnetic resonance frequency f(FMR) shifts from 3.38 to 4.82 GHz with an increment of Delta f(FMR) = 1440 MHz or Delta f(FMR)/f(FMR) = 43%; moreover, the damping constant a dramatically decreases from 0.035 to 0.018. These merits demonstrate that this nanocomposite multiferroic structure is promising in fabrication of tunable microwave components.

Assuming GR and taking a prior on the linear matter power spectrum at high redshift from the cosmic microwave background (CMB), anisotropic clustering of the CMASS DR9 galaxies alone constrains Omega(m) = 0.308 +/- 0.022 and 100 Omega(k) = 5.9 +/- 4.8 for w = -1, or w = -0.91 +/- 0.12 for Omega(k) = 0. When combined with the full CMB likelihood, the addition of the anisotropic clustering measurements to the spherically averaged baryon acoustic oscillation location increases the constraining power on DE by a factor of 4 in a flat cold dark matter (CDM) cosmology with constant DE equation of state w (giving w = -0.87 +/- 0.05). This impressive gain depends on our measurement of both the growth of structure and the Alcock-Paczynski effect, and is not realized when marginalizing over the amplitude of redshift-space distortions. Combining with both the CMB and Type Ia supernovae, we find Omega(m) = 0.281 +/- 0.014 and 1000 Omega(k) = -9.2 +/- 5.0 for w = -1, or w(0) = -1.13 +/- 0.12 and w(a) = 0.65 +/- 0.36 assuming Omega(k) = 0. Finally, when a Lambda CDM background expansion is assumed, the combination of our estimate of the growth rate with previous growth measurements provides tight constraints on the parameters describing possible deviations from GR giving gamma = 0.64 +/- 0.05. For one-parameter extensions of the flat Lambda CDM model, we find a similar to 2 sigma preference either for w > -1 or slower growth than in GR. However, the data are fully consistent with the concordance model, and evidence for these additional parameters is weaker than 2 sigma.

Our formulation involves a non-perturbative resummation of Lagrangian perturbation theory and indeed can be viewed as a partial resummation of the formalism of Matsubara in which we keep exponentiated all of the terms which tend to a constant at large separation. One of the key features of our method is that we naturally recover the Zel'dovich approximation as the lowest order of our expansion for the matter correlation function. We compare our results against a suite of N-body simulations and obtain good agreement for the correlation functions in real space and for the monopole correlation function in redshift space. The agreement becomes worse for higher multipole moments of the redshift-space, halo correlation function. Our formalism naturally includes non-linear bias and explains the strong bias-dependence of the multipole moments of the redshift-space correlation function seen in N-body simulations.

We assume an ideal gas behaviour following an equation of state with a fixed ratio of the specific heats, gamma = 1.42, consistent with the conditions of a moderate-temperature background disc with solar composition. No radiative heating or cooling is included in the models. We employ a nested grid hydrodynamic code implementing the 'Piecewise Parabolic Method' with as many as six fixed nested grids, providing spatial resolution on the finest grid comparable to the present-day diameters of Neptune and Uranus. We find that a strongly dynamically active flow develops such that no static envelope can form. The activity is not sensitive to plausible variations in the rotation curve of the underlying disc. It is sensitive to the thermodynamic treatment of the gas, as modelled by prescribed equations of state (either 'locally isothermal' or 'locally isentropic') and the temperature of the background disc material. The activity is also sensitive to the shape and depth of the core's gravitational potential, through its mass and gravitational softening coefficient. Each of these factors influences the magnitude and character of hydrodynamic feedback of the small-scale flow on the background, and we conclude that accurate modelling of such feedback is critical to a complete understanding of the core accretion process. The varying flow pattern gives rise to large, irregular eruptions of matter from the region around the core which return matter to the background flow: mass in the envelope at one time may not be found in the envelope at any later time. No net mass accretion into the envelope is observed over the course of the simulation and none is expected, due to our neglect of cooling. Except in cases of very rapid cooling however, as defined by locally isothermal or isentropic treatments, any cooling that does affect the envelope material will have limited consequences for the dynamics, since the flow quickly carries cooled material out of the core's environment entirely. The angular momentum of material in the envelope, relative to the core, varies both in magnitude and in sign on time-scales of days to months near the core and on time-scales a few years at distances comparable to the Hill radius. The dynamical activity contrasts with the largely static behaviour typically assumed within the framework of the core accretion model for Jovian planet formation. We show that material entering the dynamically active environment may suffer intense heating and cooling events the durations of which are as short as a few hours to a few days. Shorter durations are not observable in our work due to the limits of our resolution. Peak temperatures in these events range from T similar to 1000K to as high as T similar to 3-4000 K, with densities rho similar to 10(-9) to 10(-8) g cm(-3). These time-scales, densities and temperatures span a range consistent with those required for chondrule formation in the nebular shock model. We therefore propose that dynamical activity in the Jovian planet formation environment could be responsible for the production of chondrules and other annealed silicates in the solar nebula.

Antibiotic selection is typically based on the susceptibility of individual microbial strains to specific antibiotics in vitro. Often this approach cannot accurately predict medical outcomes because of factors both technical and biological. Recent culture-independent assessments of the airway microbial and viral communities demonstrated that the CF airway infection is considerably more complex and dynamic than previously appreciated. Understanding the ecological and evolutionary pressures that shape these communities is critically important for the optimal use of current therapies (in both the choice of therapy and timing of administration) and the development of newer strategies. The climax-attack model (CAM) presented here, grounded in basic ecological principles, postulates the existence of two major functional communities. The attack community consists of transient viral and microbial populations that induce strong innate immune responses. The resultant intense immune response creates microenvironments that facilitate the establishment of a climax community that is slower-growing and inherently resistant to antibiotic therapy. Newer methodologies, including sequence-based metagenomic analysis, can track not only the taxonomic composition but also the metabolic capabilities of these changing viral and microbial communities over time. Collecting this information for CF airways will enable the mathematical modeling of microbial community dynamics during disease progression. The resultant understanding of airway communities and their effects on lung physiology will facilitate the optimization of CF therapies.

Five independent deviatoric stress states were employed, for which the intermediate principal stress ranged from equal to minimum compression (axisymmetric compression) to maximum compression (axisymmetric extension). For each deviatoric stress state, five constant mean stress tests were conducted, covering mean stresses ranging from brittle to ductile failure. At low mean stresses, shear bands formed, and the peak stress required to induce failure decreased with increasing intermediate principal stress. Thus, failure at low mean stresses depends on the third invariant of deviatoric stress. Shear bands formed under all deviatoric stress states and over a wide range of mean stresses. The band angle (defined as the angle between the band normal and the direction of maximum compression) decreased with increasing mean stress. There was no clear trend in band angle with respect to intermediate principal stress; however, a small trend would be obscured by data scatter due to specimen variability. At higher mean stresses, no localization was observed. The upper bound mean stress at which shear localization occurred increased with increasing intermediate principal stress. Therefore, the mean stress that demarcates the brittle-ductile transition depends on the third invariant of deviatoric stress. Citation: Ingraham, M. D., K. A. Issen, and D. J.

The new velocities reveal that the clockwise rotations, relative to North America, seen in Oregon and western Washington from earlier GPS observations, continue to the east to include the Snake River Plain of Idaho and south into the Basin and Range of northern Nevada. Regional-scale rotation is attributed to gravitationally driven extension in the Basin and Range and Pacific-North America shear transferred through the Walker Lane belt aided by potentially strong pinning below the Idaho Batholith. The large rotating section comprising eastern Oregon displays very low internal deformation rates despite seismological evidence for a thin crust, warm mantle, organized mantle flow, and elevated topography. The observed disparity between mantle and surface kinematics suggests that either little stress acts between them(low basal shear) or that the crust is strong relative to the mantle. The rotation of the Oregon block impinges on Washington across the Yakima fold-thrust belt where shortening occurs in a closing-fan style. Elastic fault locking at the Cascadia subduction zone is reevaluated using the GPS velocities and recently published uplift rates. The 18 year GPS and 80 year leveling data can both be matched with a common locking model suggesting that the locking has been stable over many decades. The rate of strain accumulation is consistent with hundreds of years between great subduction events. Citation: McCaffrey, R., R. W. King, S. J. Payne, and M.

TI A new structural framework for integrating replication protein A into DNA processing machinery SO NUCLEIC ACIDS RESEARCH LA English DT Article ID SINGLE-STRANDED-DNA; SMALL-ANGLE SCATTERING; X-RAY-SCATTERING; GENERALIZED BORN MODEL; 70 KDA SUBUNIT; MOLECULAR-DYNAMICS; FUNCTIONAL-ANALYSIS; NEUTRON-SCATTERING; CONTRAST VARIATION; BINDING DOMAINS AB By coupling the protection and organization of single-stranded DNA (ssDNA) with recruitment and alignment of DNA processing factors, replication protein A (RPA) lies at the heart of dynamic multiprotein DNA processing machinery. Nevertheless, how RPA coordinates biochemical functions of its eight domains remains unknown. We examined the structural biochemistry of RPA's DNA-binding activity, combining small-angle X-ray and neutron scattering with all-atom molecular dynamics simulations to investigate the architecture of RPA's DNA-binding core. The scattering data reveal compaction promoted by DNA binding; DNA-free RPA exists in an ensemble of states with inter-domain mobility and becomes progressively more condensed and less dynamic on binding ssDNA. Our results contrast with previous models proposing RPA initially binds ssDNA in a condensed state and becomes more extended as it fully engages the substrate. Moreover, the consensus view that RPA engages ssDNA in initial, intermediate and final stages conflicts with our data revealing that RPA undergoes two (not three) transitions as it binds ssDNA with no evidence for a discrete intermediate state. These results form a framework for understanding how RPA integrates the ssDNA substrate into DNA processing machinery, provides substrate access to its binding partners and promotes the progression and selection of DNA processing pathways.

In this Letter, we report our recent progress on the study of electronic structures of ex-situ grown topological insulator thin films by angle resolved photoemission spectroscopy (ARPES). We successfully obtained the topological band structures of molecular beam epitaxial HgTe and vapor-solid grown Bi2Te3 thin films after proper surface cleaning procedures. This new development will not only enable us to study more topological insulators that cannot be measured by conventional in-situ ARPES technique (e. g. by cleaving or growing samples in-situ), but also open the door to directly characterize the electronic properties of topological insulators used in functional devices.

In the current study, processes to produce either ethanol or a representative fatty acid ethyl ester (FAEE) via the fermentation of sugars liberated from lignocellulosic materials pretreated in acid or alkaline environments are analyzed in terms of economic and environmental metrics. Simplified process models are introduced and employed to estimate fuel production, greenhouse gas emissions, net energy consumption, minimum fuel selling price, and water consumption for both processes. Monte Carlo analyses were carried out to identify key sources of uncertainty and variability, and an analysis of the impact of potential improvements to the FAEE process was performed. We find that the near-term performance of processes to produce FAEE is significantly worse than that of ethanol production processes for all metrics considered, primarily due to poor fermentation yields and higher electricity demands for aerobic fermentation. Even if these issues are addressed in the longer term, the reduced cost and energy requirements of FAEE separation processes will be at least partially offset by inherent limitations in the relevant metabolic pathways that constrain the maximum yield potential of FAEE from biomass-derived sugars.

Survey data in 2002 and 2005 indicated that 1.44 Mt of firewood is used in BC residential heating annually. If current wood-burning residential heating equipments were replaced by their pellet-equivalent counterparts, then only 667 kt of wood pellets would be needed annually and the impacts on human health, ecosystem quality, climate change, and primary energy consumption will be reduced fractionally by 95%, 26%, 17% and 34%, respectively. Savings of $749,277,000 per year in externality can also be achieved, representing a fractional reduction of 94% from the current practice. For every tonne of pellet burnt to replace firewood, $1124 in externality is avoided. In terms of capital investment for new equipment, replacing conventional fireplace, masonry heater and outdoor boiler are desirable whether bulk or bagged pellets are to be used. If bulk pellets are to be utilized then all users except the owners of any type of fireplace inserts should consider switching to wood pellets. For the equipment and pellet type combinations with negative net present value (NPV), the estimated external cost savings and the NPV calculated may be the basis for the establishment of an incentive program. Promoting pellet consumption for residential heating through introducing government subsidies and improving distribution logistics will be beneficial to both pellet producers and local consumers, as well as to the local environment.

This is consistent with single crystal diffraction results at 250 and 90 K, which show a slight modification of the crystal packing and Fe-N bond lengths. Ageing of the samples leads to more cooperative SCO behaviour, as evidenced by a concomitant increase in the width of the hysteresis loops (reaching up to 20 K) and a decrease in the residual HS fraction at low temperatures. These increases in the bistable domain of the sample, corroborated by measuring the changes in heat capacity through differential scanning calorimetry, are accompanied by a loss of crystallinity, which is attributed to solvent loss and the absorption of atmospheric water. Grinding an aged sample yields a narrower hysteresis loop at higher temperatures. Compound 1 was compared with two previously observed systems of the same family that exhibit different SCO behaviour, [Fe(H4L)(2)]-(ClO4)center dot 2H2O center dot 2(CH3)(2)CO (2) and [Fe(H4L)(2)] (ClO4)(2)center dot 2C(3)H(7)OH (3), by using Hirshfeld surface analysis to have a global view of the intermolecular interactions as enhanced by the functional groups of H4L.

TI Dinuclear Complexes with a Triple N1,N2-Triazole Bridge That Exhibit Partial Spin Crossover and Weak Antiferromagnetic Interactions SO EUROPEAN JOURNAL OF INORGANIC CHEMISTRY LA English DT Article DE Triazole; Coordination compounds; Iron; Spin crossover; Magnetic properties ID TRANSITION MOLECULAR MATERIALS; THIOCYANATE COORDINATION-COMPOUNDS; LANGMUIR-BLODGETT-FILMS; ISING-LIKE SYSTEMS; MAGNETIC-PROPERTIES; CRYSTAL-STRUCTURE; 1,2,4-TRIAZOLE COMPLEXES; MOSSBAUER-SPECTROSCOPY; COMPOUND; TRINUCLEAR AB The reaction of 4-phenylimino-1,2,4-triazole (1) with Fe-II, Co-II, Ni-II and Cu-II thiocyanate produces a series of analogous dinuclear compounds of formula [M-2(1)(5)(NCS)(4)] (2-5) as demonstrated by single-crystal X-ray diffraction studies of the Fe-II (2) and Co-II (3) analogues. The magnetic properties of [Fe-2(1)(5)(NCS)(4)]center dot xMeOH (x = 3.5-5) reveal a partial and gradual spin crossover (SCO) centred at T-SCO = 115 K. This is confirmed by its crystal structure solved at 100, 150 and 250 K, which exhibits a gradual decrease of the Fe-N bond lengths with temperature. However, the bulk hydrated form of 2 that is generated upon exposure to air of crystals is a high-spin compound that exhibits weak antiferromagnetic interaction. The exchange coupling among the Fe-II S = 2 ions within the dinuclear neutral complex was evaluated as J/k(B) = -1.33(3) K by using the Heisenberg Hamiltonian H = -2JS(1)center dot S-2. Similarly, the magnetic properties of the Ni-II (4) and Cu-II (5) analogues are dominated by moderate and weak antiferromagnetic interactions evaluated as J/k(B) = -13.9(3) and -0.30(5) K, respectively. The presence of strong spin-or-bit coupling of the individual Co-II ions impeded the evaluation of the likely antiferromagnetic interaction that leads to a singlet ground state in 3. The reported structures of 2 and 3 are new additions to a very scarce family of dinuclear complexes bearing a unique triple N1,N2-triazole bridge. Owing to its relevance in the peculiar properties of 1D triazole-based SCO materials, which are widely studied for their various potential applications, a structural analysis of this triple N1,N2-triazole bridge in reported structures of Fe-II and Co-II trinuclear and 1D compounds is provided.

TI Reflection of solar wind hydrogen from the lunar surface SO JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS LA English DT Article ID ION MASS-SPECTROMETRY; LOW-ENERGY HYDROGEN; HOT GAS; OUTER HELIOSPHERE; DUST GRAINS; PICKUP IONS; EXPLORER; REGOLITH; SYSTEM; CARBON AB The solar wind continuously flows out from the Sun and directly interacts with the surfaces of dust and airless planetary bodies throughout the solar system. A significant fraction of solar wind ions reflect from an object's surface as energetic neutral atoms (ENAs). ENA emission from the Moon was first observed during commissioning of the Interstellar Boundary Explorer (IBEX) mission on 3 December 2008. We present the analysis of 10 additional IBEX observations of the Moon while it was illuminated by the solar wind. For the viewing geometry and energy range (> 250 eV) of the IBEX-Hi ENA imager, we find that the spectral shape of the ENA emission from the Moon is well-represented by a linearly decreasing flux with increasing energy. The fraction of the incident solar wind ions reflected as ENAs, which is the ENA albedo and defined quantitatively as the ENA reflection coefficient R-N, depends on the incident solar wind speed, ranging from 0.2 for slow solar wind to 0.08 for fast solar wind. The average energy per incident solar wind ion that is reflected to space is 30 eV for slow solar wind and 45 eV for fast solar wind. Once ionized, these ENAs can become pickup ions in the solar wind with a unique spectral signature that reaches 3v(SW). These results apply beyond the solar system; the reflection process heats plasmas that have significant bulk flow relative to interstellar dust and cools plasmas having no net bulk flow relative to the dust.

We studied whether alevins that were exposed to six levels of dissolved gas ranging from 100% to 130% TDG at three development periods between hatch and emergence (hereafter, early, middle, and late stages) experienced differential mortality, growth, gas bubble disease, or seawater tolerance. Each life stage was exposed for 49 d (early stage), 28 d (middle stage), or 15 d (late stage) beginning at 13, 34, and 47 d posthatch, respectively, through emergence. Mortality for all stages was estimated to be 8% (95% confidence interval [CI] = 412%) when dissolved gas levels were less than 117% TDG. Mortality increased as dissolved gas levels rose above 117% TDG; the lethal concentration producing 50% mortality was 128.7% TDG (95% CI = 127.2130.3% TDG) in the early and middle stages. There was no evidence that gas exposure affected growth. The proportion of fish with gas bubble disease increased with increasing gas concentrations, and bubbles occurred most commonly in the nares and gastrointestinal tract. Early stage fish exhibited higher ratios of filamental to lamellar gill chloride cells than late-stage fish, and these ratios increased and decreased for early and late-stage fish, respectively, as gas levels increased; however, there were no significant differences in mortality between life stages after 96h in seawater. The study results suggest that water quality guidelines for dissolved gas (105% TDG) offer a conservative level of protection to Chum Salmon alevins incubating in gravel habitat downstream of Bonneville Dam.

TI A bivariate mixed distribution with a heavy-tailed component and its application to single-site daily rainfall simulation SO WATER RESOURCES RESEARCH LA English DT Article ID MARKOV-CHAIN MODEL; LOW-FREQUENCY VARIABILITY; STOCHASTIC GENERATION; DAILY PRECIPITATION; INTERANNUAL VARIABILITY; DEPENDENCE COEFFICIENT; NONPARAMETRIC APPROACH; PATTERNS; OVERDISPERSION; SEQUENCES AB This paper presents an improved bivariate mixed distribution, which is capable of modeling the dependence of daily rainfall from two distinct sources (e. g., rainfall from two stations, two consecutive days, or two instruments such as satellite and rain gauge). The distribution couples an existing framework for building a bivariate mixed distribution, the theory of copulae and a hybrid marginal distribution. Contributions of the improved distribution are twofold. One is the appropriate selection of the bivariate dependence structure from a wider admissible choice (10 candidate copula families). The other is the introduction of a marginal distribution capable of better representing low to moderate values as well as extremes of daily rainfall. Among several applications of the improved distribution, particularly presented here is its utility for single-site daily rainfall simulation. Rather than simulating rainfall occurrences and amounts separately, the developed generator unifies the two processes by generalizing daily rainfall as a Markov process with autocorrelation described by the improved bivariate mixed distribution. The generator is first tested on a sample station in Texas. Results reveal that the simulated and observed sequences are in good agreement with respect to essential characteristics. Then, extensive simulation experiments are carried out to compare the developed generator with three other alternative models: the conventional two-state Markov chain generator, the transition probability matrix model, and the semiparametric Markov chain model with kernel density estimation for rainfall amounts. Analyses establish that overall the developed generator is capable of reproducing characteristics of historical extreme rainfall events and is apt at extrapolating rare values beyond the upper range of available observed data. Moreover, it automatically captures the persistence of rainfall amounts on consecutive wet days in a relatively natural and easy way. Another interesting observation is that the recognized "overdispersion" problem in daily rainfall simulation ascribes more to the loss of rainfall extremes than the under-representation of first-order persistence. The developed generator appears to be a sound option for daily rainfall simulation, especially in particular hydrologic planning situations when rare rainfall events are of great importance.

TI Pore-scale evaluation of uranyl phosphate precipitation in a model groundwater system SO WATER RESOURCES RESEARCH LA English DT Article ID PARTIAL MOLAL PROPERTIES; TRANSVERSE MIXING ZONE; THERMODYNAMIC BEHAVIOR; THEORETICAL PREDICTION; ACTIVITY-COEFFICIENTS; AQUEOUS-ELECTROLYTES; URANIUM DEPOSIT; HIGH-PRESSURES; COLES HILL; HYDROXYAPATITE AB The abiotic precipitation of uranium (U(VI)) was evaluated in a microfluidic pore network (i.e., micromodel) to assess the efficacy of using a phosphate amendment to immobilize uranium in groundwater. U(VI) was mixed transverse to the direction of flow with hydrogen phosphate (HPO42-), in the presence or absence of calcium (Ca2+) or sulfate (SO42-), in order to identify precipitation rates, morphology and types of minerals formed, and effects of mineral precipitates on pore blockage. Precipitation occurred over the time scale of hours to days. Relative to when only U(VI) and HPO42- were present, precipitation rates were 2.3 times slower when SO42- was present, and 1.4 times faster when Ca2+ was present; larger crystals formed in the presence of SO42-. Raman backscattering spectroscopy and micro-X-ray diffraction results both showed that the only mineral precipitated was chernikovite, UO2HPO4 center dot 4H(2)O; energy dispersive X-ray spectroscopy results indicate that Ca and S are not incorporated into the chernikovite lattice. A pore-scale model was developed, and simulation results of saturation ratio (SR = Q/K-sp) suggest that chernikovite is the least thermodynamically favored mineral to precipitate (0 < SR < 1) compared to uranyl hydrogen phosphate and Na-autunite (13 < SR < 40), and uranyl orthophosphate and Ca-autunite (when Ca2+ is present; SR > 10(5)). Fluorescent tracer studies and laser confocal microscopy images showed that densely aggregated precipitates blocked pores and reduced permeability. The results suggest that uranium precipitation with phosphate as chernikovite is rapid on the time scale of remediation for the conditions considered and can block pores, alter fluid flow paths, and potentially limit mixing and precipitation.

TI Recognizing and modeling variable drawdown due to evapotranspiration in a semiarid riparian zone considering local differences in vegetation and distance from a river source SO WATER RESOURCES RESEARCH LA English DT Article ID HYDROGEOPHYSICAL RESEARCH SITE; SOUTHERN GREAT-PLAINS; CLEAR-SKY DAYS; WATER-TABLE; UNCONFINED AQUIFER; POPULUS-FREMONTII; FLOW; FLUCTUATIONS; GROUNDWATER; REMOTE AB Riparian zones in semiarid regions often exhibit high rates of evapotranspiration (ET) in spite of low-soil moisture content due to the presence of phreatophytic vegetation that is able to withdraw water from shallow aquifers. This work seeks to better define the relationship between ET, the saturated zone and the river boundary by comparing observed water table drawdown records to analytically modeled drawdown in fully penetrating wells of an unconfined aquifer in response to daily ET flux. ET at the Boise Hydrogeophysical Research Site (BHRS), a riparian zone in a temperate, semiarid environment, is calculated using a radiation-based method to provide ET values at four different wells with different vegetation densities. Analytically modeled drawdown response to ET forcing shows that drawdown magnitude increases with increasing distance from the river edge even as the surficial ET forcing remains constant. This behavior is also observed in well hydrographs and shows the buffering effect that flow from the river has on drawdown in fully penetrating riparian wells in highly permeable, unconfined aquifers. Relative contributions of river water to aquifer storage are calculated for ET-induced diurnal fluctuations of the water table at increasing distances from the river boundary. Failure to account for these spatial differences in drawdown related to the river source may explain some errors associated with estimating ET from well hydrographs alone.

TI Characterizing particle-scale equilibrium adsorption and kinetics of uranium(VI) desorption from U-contaminated sediments SO WATER RESOURCES RESEARCH LA English DT Article ID SURFACE COMPLEXATION MODEL; LONG-TERM SORPTION; REACTIVE TRANSPORT; SOLUTE-TRANSPORT; ORGANIC CONTAMINANTS; NATURAL SEDIMENTS; HANFORD SEDIMENTS; SUBSURFACE MEDIA; AQUIFER; MICROPORES AB Rates of U(VI) release from individual dry-sieved size fractions of a field-aggregated, field-contaminated composite sediment from the seasonally saturated lower vadose zone of the Hanford 300-Area were examined in flow-through reactors to maintain quasi-constant chemical conditions. The principal source of variability in equilibrium U(VI) adsorption properties of the various size fractions was the impact of variable chemistry on adsorption. This source of variability was represented using surface complexation models (SCMs) with different stoichiometric coefficients with respect to hydrogen ion and carbonate concentrations for the different size fractions. A reactive transport model incorporating equilibrium expressions for cation exchange and calcite dissolution, along with rate expressions for aerobic respiration and silica dissolution, described the temporal evolution of solute concentrations observed during the flow-through reactor experiments. Kinetic U(VI) desorption was well described using a multirate SCM with an assumed lognormal distribution for the mass-transfer rate coefficients. The estimated mean and standard deviation of the rate coefficients were the same for all <2 mm size fractions but differed for the 2-8 mm size fraction. Micropore volumes, assessed using t-plots to analyze N-2 desorption data, were also the same for all dry-sieved <2 mm size fractions, indicating a link between micropore volumes and mass-transfer rate properties. Pore volumes for dry-sieved size fractions exceeded values for the corresponding wet-sieved fractions. We hypothesize that repeated field wetting and drying cycles lead to the formation of aggregates and/or coatings containing (micro)pore networks which provided an additional mass-transfer resistance over that associated with individual particles. The 2-8 mm fraction exhibited a larger average and standard deviation in the distribution of mass-transfer rate coefficients, possibly caused by the abundance of microporous basaltic rock fragments.

Many diverse multiphysics applications can be reduced, en route to their computational simulation, to a common algebraic coupling paradigm. Mathematical analysis of multiphysics coupling in this form is not always practical for realistic applications, but model problems representative of applications discussed herein can provide insight. A variety of software frameworks for multiphysics applications have been constructed and refined within disciplinary communities and executed on leading-edge computer systems. We examine several of these, expose some commonalities among them, and attempt to extrapolate best practices to future systems. From our study, we summarize challenges and forecast opportunities.

Cells were non-motile with a disc-shaped morphology, 0.3-1 mu m in diameter and 0.1-0.2 mu m thick, and characteristic indentations on opposite flat sides of the cell. Growth occurred in completely synthetic, reduced medium amended with a haloorganic electron acceptor (mostly chlorinated but also some brominated compounds), hydrogen as electron donor, acetate as carbon source, and vitamins. No other growth-supporting redox couples were identified. Aqueous hydrogen consumption threshold concentrations were <1 nM. Growth ceased when vitamin B-12 was omitted from the medium. Addition of sterile cell-free supernatant of Dehalococcoides-containing enrichment cultures enhanced dechlorination and growth of strains 195 and FL2, suggesting the existence of so-far unidentified stimulants. Dechlorination occurred between pH 6.5 and 8.0 and over a temperature range of 15-35 degrees C, with an optimum growth temperature between 25 and 30 C. The major phospholipid fatty acids were 14 :0 (15.7 mol%), br15 : 0 (6.2 mol%), 16 :0 (22.7 mol%), 10-methyl 16 :0 (25.8 mol%) and 18 :0 (16.6 mol%). Unusual furan fatty acids including 9-(5-pentyl-2-furyl)-nonanoate and 8-(5-hexyl-2-furyl)-octanoate were detected in strains FL2, BAV1 and GT, but not in strains 195(T) and CBDB1. The 16S rRNA gene sequences of the six isolates shared more than 98% identity, and phylogenetic analysis revealed an affiliation with the phylum Chloroflexi and more than 10% sequence divergence from other described isolates. The genome sizes and G+C contents ranged from 1.34 to 1.47 Mbp and 47 to 48.9 mol% G+C, respectively. Based on 16S rRNA gene sequence comparisons, genome-wide average nucleotide identity and phenotypic characteristics, the organohalide-respiring isolates represent a new genus and species, for which the name Dehalococcoides mccartyi gen. nov., sp. nov. is proposed. Isolates BAV1 (=ATCC BAA-2100 =JCM 16839 =KCTC 5957), FL2 (=ATCC BAA-2098 =DSM 23585 =JCM 16840 =KCTC 5959), GT (=ATCC BAA-2099 =1CM 16841 =KCTC 5958), CBDB1, 195(T) (=ATCC BAA-2266(T) =KCTC 15142T) and VS are considered strains of Dehalococcoides mccartyi, with strain 195T as the type strain. The new class Dehalococcoidia classis nov., order Dehalococcoidales ord. nov. and family Dehalococcoidaceae fam. nov. are described to accommodate the new taxon.

In this paper, we develop architecture-aware methods to accelerate all-pairs computations on many-core graphics processors. Pairwise computations occur frequently in numerous application areas in scientific computing. While they appear easy to parallelize due to the independence of computing each pairwise interaction from all others, development of techniques to address multi-layered memory hierarchies, mapping within the restrictions imposed by the small and low-latency on-chip memories, striking the right balanced between concurrency, reuse and memory traffic etc., are crucial to obtain high-performance. We present a hierarchical decomposition scheme for CPUs based on decomposition of the output matrix and input data. We demonstrate that a careful tuning of the involved set of decomposition parameters is essential to achieve high efficiency on the CPUs. We also compare the performance of our strategies with an implementation on the STI Cell processor as well as multi-core CPU parallelizations using OpenMP and Intel Threading Building Blocks.

TI Litter chemistry changes more rapidly when decomposed at home but converges during decomposition-transformation SO SOIL BIOLOGY & BIOCHEMISTRY LA English DT Article DE Litter decomposition; Litter chemistry; Soil organic matter; Soil formation; Home-field advantage; Pyrolysis-molecular beam mass spectrometry; Lignin; Microbial products ID SOIL ORGANIC-MATTER; BEAM MASS-SPECTROMETRY; HIGH-ELEVATION FORESTS; LEAF-LITTER; PLANT LITTER; LIGNIN CONTROL; PINE FOREST; PY-MBMS; DYNAMICS; CARBON AB Recent evidence suggests that soil organic matter (SOM) is largely composed of microbial products rather than plant compounds that resist decomposition. The chemical transformation of leaf litter components during decomposition is critical in controlling SOM formation. Plant leaf litter tends to decompose faster in its native environment than when it is placed under other vegetation types. This home-field advantage (HFA) suggests that decomposer communities are specialized to most efficiently degrade the litter found in their native environment, possibly through the production of specific enzymes that degrade unique compounds within that litter. Could this affect the degree to which leaf litter chemistry is altered during decomposition? We used pyrolysis-molecular beam mass spectrometry (py-MBMS) to analyze whether the chemistry of aspen and lodgepole pine litter was altered to a greater degree when decomposed in its home environment compared to an away environment. We had previously reported a 4% HFA for pine litter decomposition rates in this reciprocal experiment, and attributed that effect to differences in decomposer communities. Our high-resolution analysis revealed that litter chemistry also changed to a greater extent in its home environment. The changes in litter chemistry were more pronounced for the more recalcitrant pine litter, suggesting that decomposer community specialization is more important for recalcitrant litter. The accumulation of microbial products and microbially-transformed plant components resulted in an overall convergence in litter chemistry as decomposition proceeded, but the imprints of both initial litter chemistry and decomposer communities remained evident. The detection of new compounds in decomposed litter and the HFA effect on litter chemistry suggest that decomposer communities affect both the rate at which individual compounds within litter are decomposed, and the chemical nature of compounds that are incorporated into SOM.

The impacts of cultivation and over-sowing with exotic grass and legumes on soil microbiology were assessed at four sites in New Zealand which differed in soil type, climate and vegetation. Primary alteration of the soil physicochemical status occurred with land use change. This was driven by addition of mineral fertiliser and alteration of pH. Genes associated with several biogeochemical cycles (GeoChip data) were impacted by land-use but not sampling location. A number of functional gene families associated with biogeochemical cycling of C. N and S were present in greater relative abundance in the undisturbed soils. Similarly, soil bacterial (PhyloChip) and fungal (TRFLP) communities were strongly influenced by land-use change, but unaffected by sampling location. Alteration of land-use increased the relative abundance of Firmicutes, Actinobacteria and OD1 phyla, but many of the less-common phyla, such as Verrucomicrobia and Dictyoglomi decreased in abundance; these phyla may be important in internal soil nutrient cycling processes. This work provides evidence that tussock grassland soils are strongly dependent on microbially-mediated nutrient cycling, and these processes are highly-sensitive to exogenous nutrient inputs and/or alteration of pH. De-coupling of processes following addition of fertilisers or removal of organic matter (grazing) may make these improved grassland systems more susceptible to nutrient leakage. This has important implications for environmental quality. (C) 2012 Elsevier Ltd. All rights reserved.

We evaluate the impact of soil attributes, microbial functional group biomass, and cropping system type on soil amino sugar profiles in three model biofuel cropping systems in southern Wisconsin, USA. Total soil carbon and clay content explained differences in soil amino sugar profiles, with glucosamine and galactosamine more strongly related to soil carbon and muramic acid associated with clay content. Amino sugars were not correlated to cropping system or to microbial functional group lipid abundance, suggesting amino sugar differences among locations were due to differences in soil legacy properties such as total carbon, clay content and culture age rather than to current biotic drivers. The disconnect between the current biotic composition and legacies of past microbial activity suggests that microbial residues should be considered as trajectories over time rather than static system properties.

We showed that the related Schimel and Weintraub RM-M equation (RM-M SW) can be derived from the Langmuir adsorption isotherm theory with S >> Eo. Both the M M and the RM-M-SW are appropriate to field soil conditions with S >> E-0 given different values of specific reaction rate (k(3)) and half-saturation constant (K-s). In contrast to M M and RM-M-SW models, the RM-M model is not applicable to field conditions because of its limited application to one substrate with a simple enzyme system. However, we demonstrate that the best formulation for the process of enzyme-mediated decomposition may vary depending on whether the process is limited by substrate or enzyme availability.

TI Remote Monitoring of Freeze-Thaw Transitions in Arctic Soils Using the Complex Resistivity Method SO VADOSE ZONE JOURNAL LA English DT Article ID FREQUENCY ELECTRICAL-PROPERTIES; INDUCED-POLARIZATION; DIELECTRIC-RELAXATION; POINT DEPRESSION; PERMAFROST THAW; UNFROZEN WATER; FROZEN SOILS; ICE; CONDUCTIVITY; SURFACE AB Our ability to monitor freeze-thaw transitions is critical to developing a predictive understanding of biogeochemical transitions and carbon dynamics in high latitude environments. In this study, we conducted laboratory column experiments to explore the potential of the complex resistivity method for monitoring the freeze thaw transitions of the arctic permafrost soils. Samples for the experiment were collected from the upper active layer of Gelisol soils at the Barrow Environmental Observatory (BEO) in Barrow, Alaska. Freeze thaw transitions were induced through exposing the soil column to controlled temperature environments at 4 and -20 degrees C. Complex resistivity and temperature measurements were collected regularly during the freeze thaw transitions using electrodes and temperature sensors installed along the column. During the experiments, over two orders of magnitude of resistivity variations were observed when the temperature was increased or decreased between -20 and 0 degrees C. Smaller resistivity variations were also observed during the isothermal thawing or freezing processes that occurred near 0 degrees C. Single frequency electrical phase response and imaginary conductivity at 1 Hz were found to be exclusively related to the unfrozen water in the soil matrix, suggesting that these geophysical attributes can be used as a proxy for the monitoring of the onset and progression of the freeze thaw transitions. Spectral electrical responses and fitted Cole Cole parameters contained additional information about the freeze thaw transition affected by the soil grain size distribution. Specifically, a shift of the observed spectral response to lower frequency was observed during the isothermal thawing process, which we interpret to be due to sequential thawing, first from fine particles and then to coarse particles within the soil matrix. Our study demonstrates the potential of the complex resistivity method for remote monitoring of freeze thaw transitions in arctic soils. Although conducted at the laboratory scale, this study provides the foundation for exploring the potential of the complex resistivity signals for monitoring spatiotemporal variations of freeze thaw transitions over field-relevant scales.

This paper reports on the combined electrochemical characterization, in situ X-ray diffraction and fluorescence research, and scanning electron microscopic studies of nucleation and growth of Cu on individual carbon fibers. Compared to the flat glassy carbon substrates and Au thin film substrates, the onset potential of Cu electrodeposition on individual carbon microfiber is more negative with lower efficiencies, indicating the difficulty of Cu nucleation on carbon fiber surface. Utilizing the capability of synchrotron X-ray microbeam diffraction and fluorescence spectroscopy techniques, real time Cu crystalline structure and composition evolvement information during the electrochemical reaction processes have been studied. In situ study reveals random Cu grain formation and anisotropic growth. Dynamic Cu growth and dissolution were found to occur simultaneously during deposition. Cu nuclei density and size can be effectively controlled, in addition to the grain morphology and stability, indicating the possibility of electrochemical manipulation of microstructure thus the properties of Cu coated carbon materials.

Dean TI A supramolecular approach to combining enzymatic and transition metal catalysis SO NATURE CHEMISTRY LA English DT Article ID DYNAMIC KINETIC RESOLUTION; SECONDARY ALCOHOLS; RACEMIZATION CATALYST; DIELS-ALDER; ENZYMES; HOST; COMPLEX; TANDEM AB The ability of supramolecular host-guest complexes to catalyse organic reactions collaboratively with an enzyme is an important goal in the research and discovery of synthetic enzyme mimics. Herein we present a variety of catalytic tandem reactions that employ esterases, lipases or alcohol dehydrogenases and gold(I) or ruthenium(II) complexes encapsulated in a Ga4L6 tetrahedral supramolecular cluster. The host-guest complexes are tolerated well by the enzymes and, in the case of the gold(I) host-guest complex, show improved reactivity relative to the free cationic guest. We propose that supramolecular encapsulation of organometallic complexes prevents their diffusion into the bulk solution, where they can bind amino-acid residues on the proteins and potentially compromise their activity. Our observations underline the advantages of the supramolecular approach and suggest that encapsulation of reactive complexes may provide a general strategy for carrying out classic organic reactions in the presence of biocatalysts.

An electron beam with a rectangular longitudinal profile is produced out of a photoinjector via stacking of the laser pulses. The beam is also run off-crest of the photoinjector rf to develop an energy chirp. After passing through a dielectric loaded waveguide, the beam's energy becomes modulated by its self-wake. In a chicane beamline following the dielectric energy-bunching section this energy modulation is converted to a density modulation-a bunch train. The density modulated beam can be sent through a power extraction section, like a dielectric loaded accelerating structure, or simply can intercept a foil target, producing THz radiation of various bandwidths and power levels.

TI Modular instrument mounting system for variable environment in operando X-ray experiments SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID ANGLE CALCULATIONS; SCATTERING; DIFFRACTOMETER; DIFFRACTION; DEPOSITION AB In the growing field of in operando and in situ X-ray experiments, there exists a large disparity in the types of environments and equipment to control them. This situation makes it challenging to conduct multiple experiments with a single mechanical interface to the diffractometer. Here, we describe the design and implementation of a modular instrument mounting system that can be installed on a standard six-circle diffractometer (e. g., 5021 Huber GmbH). This new system allows for the rapid changeover of different chambers and sample heaters and permits accurate sample positioning (x, y, z, and azimuthal rotation) without rigid coupling to the chamber body. Isolation of the sample motion from the chamber enclosure is accomplished through a combination of custom rotary seals and bellows. Control of the pressure and temperature has been demonstrated in the ranges of 10(-6)-10(3) Torr and 25 degrees C-900 degrees C, respectively. We have utilized the system with several different modular instruments. As an example, we provide in situ sputtering results, where the growth dynamics of epitaxial LaGaO3 thin films on (001) SrTiO3 substrates were investigated. (C) 2013 American Institute of Physics.

A re-entrant design is employed which allows for alignment from outside the chamber. The mirrors are coated with Pt and operate at a grazing incident angle of 0.5 degrees providing higher resolution than an equal brightness pinhole and sufficient bandwidth to image thermally shifted characteristic K-alpha emission from heated Cu tracer layers in Fast Ignition experiments. The superpolished substrates (<1 angstrom rms roughness) had a final visible wavelength roughness of 1.7 angstrom after coating, and exhibited a reflectivity corresponding to an X-ray wavelength roughness of 7 +/- 1 angstrom. A unique feature of this design is that during experiments, the unfiltered direct signal along with the one-dimensional reflections are retained on the detector in order to enable a live indication of alignment and incident angle. The broad spectral window from 4 to 9 keV enables simultaneous observation of emission from several spectral regions of interest, which has been demonstrated to be particularly useful for cone-wire targets. An experimentally measured resolution of 15 mu m has been obtained at the center of the field of view. (C) 2013 American Institute of Physics.

TI 2D divertor heat flux distribution using a 3D heat conduction solver in National Spherical Torus Experiment SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID THERMOGRAPHY AB The divertor heat flux footprint in tokamaks is often observed to be non-axisymmetric due to intrinsic error fields, applied 3D magnetic fields or during transients such as edge localized modes. Typically, only 1D radial heat flux profiles are analyzed; however, analysis of the full 2D divertor measurements provides opportunities to study the asymmetric nature of the deposited heat flux. To accomplish this an improved 3D Fourier analysis method has been successfully applied in a heat conduction solver (TACO) to determine the 2D heat flux distribution at the lower divertor surface in the National Spherical Torus Experiment (NSTX) tokamak. This advance enables study of helical heat deposition onto the divertor. In order to account for heat transmission through poorly adhered surface layers on the divertor plate, a heat transmission coefficient, defined as the surface layer thermal conductivity divided by the thickness of the layer, was introduced to the solution of heat conduction equation. This coefficient is denoted as alpha and a range of values were tested in the model to ensure a reliable heat flux calculation until a specific value of alpha led to the constant total deposited energy in the numerical solution after the end of discharge. A comparison between 1D heat flux profiles from TACO and from a 2D heat flux calculation code, THEODOR, shows good agreement. Advantages of 2D heat flux distribution over the conventional 1D heat flux profile are also discussed, and examples of 2D data analysis in the study of striated heat deposition pattern as well as the toroidal degree of asymmetry of peak heat flux and heat flux width are demonstrated.

For many applications, the most desirable electrochemical characterization requires a three-electrode cell under potentiostat control. In high throughput screening, a material library is explored by either employing an array of such cells, or rastering a single cell over the library. To attain this latter capability with unprecedented throughput, we have developed a highly integrated, compact scanning droplet cell that is optimized for rapid electrochemical and photoeletrochemical measurements. Using this cell, we screened a quaternary oxide library as (photo)electrocatalysts for the oxygen evolution (water splitting) reaction. High quality electrochemical measurements were carried out and key electrocatalytic properties were identified for each of 5456 samples with a throughput of 4 s per sample.

Quantitative measurement beyond the linear regime of the instrument is achieved by associating an instantaneous calibrated molar flow rate of gas to the detector response. This technique is based on fundamental methods, and is independently verified by comparison to the hydrogen desorption capacity of a known standard metal hydride with known stoichiometry. The TPD calibration procedure described here may be used for any pure gas, and the accuracy is demonstrated for the specific case of hydrogen. (C) 2013 American Institute of Physics.

TI Evaluation of the sensitivity limits of water vapor transmission rate measurements using electrical calcium test SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID GAS PERMEATION; BARRIER FILMS; TRANSPORT; DISPLAYS AB The development of flexible organic light emitting diode displays and flexible thin film photovoltaic devices is dependent on the use of flexible, low-cost, optically transparent and durable barriers to moisture and/or oxygen. It is estimated that this will require high barriers with water vapor transmission rates (WVTR) between 10(-4) and 10(-6) g/m(2)/day. Thus, there is a need to develop a relatively fast, low cost, and quantitative method to evaluate such low permeation rates. Prior works have demonstrated that Ca films, because they change optically and electrically upon reaction with moisture, can be used as a sensor, enabling one to calculate a WVTR between 10 and 10(-6) g/m(2)/day or better. In this work, we analyze the accuracy of an electrical Ca test method. We focus on the effects of the addition of a diffusion spacer and the effects of interactions of edge-seal material with changes to the spacer contacting surface on the overall accuracy. Furthermore, we examine a series of factors that can lead to different errors resulting in qualitative rather than quantitative Ca test behavior. We demonstrate that accurate, relatively high throughput, and reproducible measurements are possible for very low WVTR films in the 10(-6) g/m(2)/day range. (C) 2013 American Institute of Physics.

The rDAC, equipped with graphite heating arrays, allows simultaneous resistive and laser heating while the material is subjected to high pressure. The goals are both to extend the temperature range of external (resistive) heating and to produce environments with lower temperature gradients in a simultaneously resistive-and laser-heated rDAC. Three different geomaterials were used as pilot samples to calibrate and optimize conditions for combined resistive and laser heating. For example, in Run#1, FeO was loaded in a boron-mica gasket and compressed to 11 GPa then gradually resistively heated to 1007 K (1073 K at the diamond side). The laser heating was further applied to FeO to raise temperature to 2273 K. In Run#2, Fe-Ni alloy was compressed to 18 GPa and resistively heated to 1785 K (1973 K at the diamond side). The combined resistive and laser heating was successfully performed again on (Mg0.9Fe0.1) O in Run#3. In this instance, the sample was loaded in a boron-kapton gasket, compressed to 29 GPa, resistive-heated up to 1007 K (1073 K at the diamond side), and further simultaneously laser-heated to achieve a temperature in excess of 2273 K at the sample position. Diffraction patterns obtained from the experiments were deconvoluted using the Rietveld method and quantified for lattice preferred orientation of each material under extreme conditions and during phase transformation.

TI Performance of an inverted ion source SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID FILTERED VACUUM-ARC AB Whereas energetic ion beams are conventionally produced by extracting ions (say, positive ions) from a plasma that is held at high (positive) potential, with ion energy determined by the potential drop through which the ions fall in the beam formation electrode system, in the device described here the plasma and its electronics are held at ground potential and the ion beam is formed and injected energetically into a space maintained at high (negative) potential. We refer to this configuration as an "inverted ion source." This approach allows considerable savings both technologically and economically, rendering feasible some ion beam applications, in particular small-scale ion implantation, that might otherwise not be possible for many researchers and laboratories. We have developed a device of this kind utilizing a metal vapor vacuum arc plasma source, and explored its operation and beam characteristics over a range of parameter variation. The downstream beam current has been measured as a function of extraction voltage (5-35 kV), arc current (50-230 A), metal ion species (Ti, Nb, Au), and extractor grid spacing and beamlet aperture size (3, 4, and 5 mm). The downstream ion beam current as measured by a magnetically-suppressed Faraday cup was up to as high as 600 mA, and with parametric variation quite similar to that found for the more conventional metal vapor vacuum arc ion source.

TI Synchrotron radiation-based far-infrared spectroscopic ellipsometer with full Mueller-matrix capability SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID TERBIUM IRON-GARNET; GENERALIZED ELLIPSOMETRY; LAYERED SYSTEMS; OPTIMUM ANGLES; THIN-FILMS; POLARIZATION; POLARIMETER; CALIBRATION; REFLECTION; MEDIA AB We developed far-IR spectroscopic ellipsometer at the U4IR beamline of the National Synchrotron Light Source in Brookhaven National Laboratory. This ellipsometer is able to measure both, rotating analyzer and full-Mueller matrix spectra using rotating retarders, and wire-grid linear polarizers. We utilize exceptional brightness of synchrotron radiation in the broad spectral range between about 20 and 4000 cm(-1). Fourier-transform infrared (FT-IR) spectrometer is used for multi-wavelength data acquisition. The sample stage has temperature variation between 4.2 and 450 K, wide range of theta-2 theta angular rotation, chi tilt angle adjustment, and X-Y-Z translation. A LabVIEW-based software controls the motors, sample temperature, and FT-IR spectrometer and also allows to run fully automated experiments with pre-programmed measurement schedules. Data analysis is based on Berreman's 4 x 4 propagation matrix formalism to calculate the Mueller matrix parameters of anisotropic samples with magnetic permeability mu not equal 1. A nonlinear regression of the rotating analyzer ellipsometry and/or Mueller matrix (MM) spectra, which are usually acquired at variable angles of incidence and sample crystallographic orientations, allows extraction of dielectric constant and magnetic permeability tensors for bulk and thin-film samples. Applications of this ellipsometer setup for multiferroic and ferrimagnetic materials with mu not equal 1 are illustrated with experimental results and simulations for TbMnO3 and Dy3Fe5O12 single crystals. We demonstrate how magnetic and electric dipoles, such as magnons and phonons, can be distinguished from a single MM measurement without adducing any modeling arguments. The parameters of magnetoelectric components of electromagnon excitations are determined using MM spectra of TbMnO3. (C) 2013 American Institute of Physics.

This new probe has clear advantages compared with previously used Bell and Sentron Hall probes: very stable zero offset (less than the noise of 0.026 G) and compensated planar Hall effect. It can be used with proper calibration even for first and second field integral measurements. A comparison with reference measurements by long stretched coil shows that the difference in the first field integral measurement results for a 2.4-m-long Undulator A device is between 17 G cm for the best of four Hall probes used for the test and 51 G cm for the worst of them for all gap ranges from 10.5 mm to 150 mm.

With a broad coverage of the momentum transfer (Q)-energy (E) space, these instruments serve an extensive user community. In an effort to further expand the scientific capabilities of the SNS instrument suites, we propose a low background, inverse geometry Brillouin inelastic spectrometer for the SNS which will expand the Q-E coverage of the current instrument suite and facilitate the study of inelastic and quasi-elastic scatterings at low Q values. The possible location for the proposed instrument is either beamline 8 which views the decoupled water moderator, or beamline 14A, which views a cold, coupled super critical hydrogen moderator. The instrument parameters, optimizations, and performances at these two beamline locations are discussed. (C) 2013 American Institute of Physics. [http://dx.doi.org/10.1063/1.4792379] C1 [Zhao, J. K.

The presence of sub-1 nm clusters was confirmed by STEM. They exhibited a striking photocatalytic activity for both liquid and gas phase oxidation reactions, which have a significant potential for environmental applications. We believe that this experimental result is the first ever experimental demonstration of very promising properties of such small clusters for environmental photocatalysis. The NO2 conversion on these catalysts was 5 times higher as compared to that of unmodified catalysts, whereas 4 times increase in activity was observed for liquid phase oxidation of phenol. Another distinct component of this work included a novel use of modified DRIFT spectroscopy for photocatalytic testing, which allowed us to observe both surface and gas phase processes in situ.

The MPPR consists of parallel photocatalytic plates irradiated by cylindrical UV lamps orthogonal to the plates. The photocatalyst titanium dioxide (TiO2) is supported on the plates as a thin film. The photoreactor design is compact and offers a large irradiated photocatalytic surface area, a high degree of photon utilization, low pressure drop and a modular design which can facilitate scale-up. These features are desirable for the decontamination of indoor air in ventilation ducts or for water detoxification. The Monte Carlo method was applied to determine three dimensionless reactor performance parameters: the photon absorption efficiency (phi), the uniformity of the distribution of the dimensionless radiation intensity (eta) and the overall photonic efficiency (Phi). The emission of photons from the light sources was simulated by the extensive source with superficial emission (ESSE) model. Simulations were performed by varying the catalyst reflectivity albedo, the number and the diameter of lamps, and the dimensions and spacing of the photocatalytic plates. Optimal design for a basic reactor module with one lamp was accomplished for lamp-diameter-to-plate-height ratio (beta) of 0.7, while the plate-spacing-to-plate-height ratio (alpha) was correlated by [alpha(optimum) = 0.191 beta(2) - 0.5597 beta + 0.3854]. A multilamp arrangement leads to a feasible increase in the size and number of the plates and the irradiated photocatalytic surface area. The optimum design was validated by measuring the apparent quantum yield of the oxidation of toluene (7 ppmv) in a humidified air stream using immobilized TiO2 (Degussa P25). Experiments performed varying the geometrical parameter alpha correlated well with the model calculations, with maximum apparent quantum yield for alpha = 0.137. The results are directly transferable to the treatment of water by photocatalysis. (C) 2012 Elsevier B.V. All rights reserved.

Around 461 TWh of electricity and 14,872 PJ of fuel were consumed to produce this quantity of steel. We identified and analyzed 23 energy efficiency technologies and measures applicable to the processes in China's iron and steel industry. Using a bottom-up electricity CSC (Conservation Supply Curve) model, the cumulative cost-effective electricity savings potential for the Chinese iron and steel industry for 2010-2030 is estimated to be 251 TWh, and the total technical electricity saving potential is 416 TWh. The CO2 emissions reduction associated with cost-effective electricity savings is 139 Mt CO2 and the CO2 emission reduction associated with technical electricity saving potential is 237 Mt CO2. The FCSC (Fuel CSC) model for the Chinese iron and steel industry shows cumulative cost-effective fuel savings potential of 11,999 PJ, and the total technical fuel saving potential is 12,139. The CO2 emissions reduction associated with cost-effective and technical fuel savings is 1191 Mt CO2 and 1205 Mt CO2, respectively.

Despite an expanding array of approaches for detecting microbes in a given sample, rapid and robust means of assessing the differential viability of these cells, as a function of phylogenetic lineage, remain elusive. In this study, pre-PCR propidium monoazide (PMA) treatment was coupled with downstream pyrosequencing and PhyloChip DNA microarray analyses to better understand the frequency, diversity and distribution of viable bacteria in spacecraft assembly cleanrooms. Sample fractions not treated with PMA, which were indicative of the presence of both live and dead cells, yielded a great abundance of highly diverse bacterial pyrosequences. In contrast, only 1% to 10% of all of the pyrosequencing reads, arising from a few robust bacterial lineages, originated from sample fractions that had been pre-treated with PMA. The results of PhyloChip analyses of PMA-treated and -untreated sample fractions were in agreement with those of pyrosequencing. The viable bacterial population detected in cleanrooms devoid of spacecraft hardware was far more diverse than that observed in cleanrooms that housed mission-critical spacecraft hardware. The latter was dominated by hardy, robust organisms previously reported to survive in oligotrophic cleanroom environments. Presented here are the findings of the first ever comprehensive effort to assess the viability of cells in low-biomass environmental samples, and correlate differential viability with phylogenetic affiliation.

TI Iron-reducing bacteria accumulate ferric oxyhydroxide nanoparticle aggregates that may support planktonic growth SO ISME JOURNAL LA English DT Article DE iron-reducing bacteria; biomineralization; correlative microscopy; cryo-transmission electron microscopy; STXM; X-ray absorption spectroscopy ID INSOLUBLE FE(III) OXIDE; C-TYPE CYTOCHROMES; X-RAY MICROSCOPES; GEOBACTER-SULFURREDUCENS; ELECTRON-TRANSFER; REDUCTION; SHEWANELLA; GROUNDWATER; OXIDATION; MINERALS AB Iron-reducing bacteria (FeRB) play key roles in anaerobic metal and carbon cycling and carry out biogeochemical transformations that can be harnessed for environmental bioremediation. A subset of FeRB require direct contact with Fe(III)-bearing minerals for dissimilatory growth, yet these bacteria must move between mineral particles. Furthermore, they proliferate in planktonic consortia during biostimulation experiments. Thus, a key question is how such organisms can sustain growth under these conditions. Here we characterized planktonic microbial communities sampled from an aquifer in Rifle, Colorado, USA, close to the peak of iron reduction following in situ acetate amendment. Samples were cryo-plunged on site and subsequently examined using correlated two-and three-dimensional cryogenic transmission electron microscopy (cryo-TEM) and scanning transmission X-ray microscopy (STXM). The outer membranes of most cells were decorated with aggregates up to 150nm in diameter composed of similar to 3 nm wide amorphous, Fe-rich nanoparticles. Fluorescent in situ hybridization of lineage-specific probes applied to rRNA of cells subsequently imaged via cryo-TEM identified Geobacter spp., a well-studied group of FeRB. STXM results at the Fe L-2,L-3 absorption edges indicate that nanoparticle aggregates contain a variable mixture of Fe(II)-Fe( III), and are generally enriched in Fe(III). Geobacter bemidjiensis cultivated anaerobically in the laboratory on acetate and hydrous ferric oxyhydroxides also accumulated mixed-valence nanoparticle aggregates. In field-collected samples, FeRB with a wide variety of morphologies were associated with nano-aggregates, indicating that cell surface Fe(III) accumulation may be a general mechanism by which FeRB can grow while in planktonic suspension.

TI Characterization and transcription of arsenic respiration and resistance genes during in situ uranium bioremediation SO ISME JOURNAL LA English DT Article DE Geobacter; arsenic respiration; arsenic resistance; gene transcription; uranium bioremediation ID BACTERIAL DISSIMILATORY REDUCTION; METAL-REDUCING BACTERIA; CONTAMINATED AQUIFER; GEOBACTER-SULFURREDUCENS; MOLECULAR ANALYSIS; SP-NOV; DESULFOTOMACULUM AURIPIGMENTUM; QUANTIFYING EXPRESSION; BANGLADESH GROUNDWATER; SUBSURFACE SEDIMENTS AB The possibility of arsenic release and the potential role of Geobacter in arsenic biogeochemistry during in situ uranium bioremediation was investigated because increased availability of organic matter has been associated with substantial releases of arsenic in other subsurface environments. In a field experiment conducted at the Rifle, CO study site, groundwater arsenic concentrations increased when acetate was added. The number of transcripts from arrA, which codes for the a-subunit of dissimilatory As(V) reductase, and acr3, which codes for the arsenic pump protein Acr3, were determined with quantitative reverse transcription-PCR. Most of the arrA (>60%) and acr3-1 (>90%) sequences that were recovered were most similar to Geobacter species, while the majority of acr3-2 (>50%) sequences were most closely related to Rhodoferax ferrireducens. Analysis of transcript abundance demonstrated that transcription of acr3-1 by the subsurface Geobacter community was correlated with arsenic concentrations in the groundwater. In contrast, Geobacter arrA transcript numbers lagged behind the major arsenic release and remained high even after arsenic concentrations declined. This suggested that factors other than As(V) availability regulated the transcription of arrA in situ, even though the presence of As(V) increased the transcription of arrA in cultures of Geobacter lovleyl, which was capable of As(V) reduction. These results demonstrate that subsurface Geobacter species can tightly regulate their physiological response to changes in groundwater arsenic concentrations. The transcriptomic approach developed here should be useful for the study of a diversity of other environments in which Geobacter species are considered to have an important influence on arsenic biogeochemistry.

Changes in rainfall patterns have important implications for the moisture content and redox status of tropical soils, yet little is known about how these changes may affect microbial community structure. Specifically, does exposure to prior stress confer increased resistance to subsequent perturbation? Here we reduced the quantity of precipitation throughfall to tropical forest soils in the Luquillo Mountains, Puerto Rico. Treatments included newly established throughfall exclusion plots (de novo excluded), plots undergoing reduction for a second time (pre-excluded) and ambient control plots. Ten months of throughfall exclusion led to a small but statistically significant decline in soil water potential and bacterial populations clearly adapted to increased osmotic stress. Although the water potential decline was small and microbial biomass did not change, phylogenetic diversity in the de novo-excluded plots decreased by similar to 40% compared with the control plots, yet pre-excluded plots showed no significant change. On the other hand, the relative abundances of bacterial taxa in both the de novo-excluded and pre-excluded plots changed significantly with throughfall exclusion compared with control plots. Changes in bacterial community structure could be explained by changes in soil pore water chemistry and suggested changes in soil redox. Soluble iron declined in treatment plots and was correlated with decreased soluble phosphorus concentrations, which may have significant implications for microbial productivity in these P-limited systems.

ANTHRACIS; PROTEIN BSLO; SURFACE; STRAINS; BINDING; TOXIN; GENES AB Bacillus cereus G9241, the causative agent of anthrax-like disease, harbors virulence plasmids encoding anthrax toxins as well as hyaluronic acid (HA) and B. cereus exopolysaccharide (BPS) capsules. B. cereus G9241 also harbors S-layer genes, including homologs of Bacillus anthracis surface array protein (Sap), extractable antigen 1 (EA1), and the S-layer-associated proteins (BSLs). In B. anthracis, S-layer proteins and BSLs attach via their S-layer homology domains (SLH) to the secondary cell wall polysaccharide (SCWP) in a manner requiring csaB, a predicted ketalpyruvate transferase. Here we used a genetic approach to analyze B. cereus G9241 S-layer assembly and function. Variants lacking the csaB gene synthesized SCWP but failed to retain Sap, EA1, and BSLs in the bacterial envelope. The B. cereus G9241 csaB mutant assembled capsular polysaccharides but displayed an increase in chain length relative to the wild-type strain. This phenotype is likely due to its inability to deposit BslO murein hydrolase at divisional septa. During growth under capsule-inducing conditions, B. cereus G9241 assembled BSLs (BslA and BslO) and the Sap S-layer protein, but not EA1, in the envelope. Finally, csaB-mediated assembly of S-layer proteins and BSLs in B. cereus G9241 contributes to the pathogenesis of anthrax-like disease in mice.

TI Role of the CipA Scaffoldin Protein in Cellulose Solubilization, as Determined by Targeted Gene Deletion and Complementation in Clostridium thermocellum SO JOURNAL OF BACTERIOLOGY LA English DT Article ID CRYSTALLINE CELLULOSE; PEPTIDE IDENTIFICATION; COMPONENTS; ULTRASTRUCTURE; CELLULASES; EXPRESSION; BACTERIA; COMPLEX; ETHANOL; BINDING AB The CipA scaffoldin protein plays a key role in the Clostridium thermocellum cellulosome. Previous studies have revealed that mutants deficient in binding or solubilizing cellulose also exhibit reduced expression of CipA. To confirm that CipA is, in fact, necessary for rapid solubilization of crystalline cellulose, the gene was deleted from the chromosome using targeted gene deletion technologies. The CipA deletion mutant exhibited a 100-fold reduction in cellulose solubilization rate, although it was eventually able to solubilize 80% of the 5 g/liter cellulose initially present. The deletion mutant was complemented by a copy of cipA expressed from a replicating plasmid. In this strain, Avicelase activity was restored, although the rate was 2-fold lower than that in the wild type and the duration of the lag phase was increased. The cipA coding sequence is located at the beginning of a gene cluster containing several other genes thought to be responsible for the structural organization of the cellulosome, including olpB, orf2p, and olpA. Tandem mass spectrometry revealed a 10-fold reduction in the expression of olpB, which may explain the lower growth rate. This deletion experiment adds further evidence that CipA plays a key role in cellulose solubilization by C. thermocellum, and it raises interesting questions about the differential roles of the anchor scaffoldin proteins OlpB, Orf2p, and SdbA.

Further, insertion of LcrV-capped needles from a calcium-rich environment into host cells may trigger the low-calcium signal for effector translocation. Here, we used a genetic approach to test the hypothesis that the needle cap responds to the low-calcium signal by promoting injectisome assembly. Growth restriction of Yersinia pestis in the absence of calcium (low-calcium response [LCR+] phenotype) was exploited to isolate dominant negative lcrV alleles with missense mutations in its amber stop codon (lcrV(*327)). The addition of at least four amino acids or the eight-residue Strep tag to the C terminus was sufficient to generate an LCR- phenotype, with variant LcrV capping type III needles that cannot assemble the YopD injectisome component. The C-terminal Strep tag appears buried within the cap structure, blocking effector transport even in Y. pestis yscF variants that are otherwise calcium blind, a constitutive type III secretion phenotype. Thus, LcrV(*327) mutants arrest the needle cap in a state in which it cannot respond to the low-calcium signal with either injectisome assembly or the activation of type III secretion. Insertion of the Strep tag at other positions of LcrV produced variants with wild-type LCR+, LCR-, or dominant negative LCR- phenotypes, thereby allowing us to identify discrete sites within LcrV as essential for its attributes as a secretion substrate, needle cap, and injectisome assembly factor.

The fundamental purpose of our studies is to determine if differences in constituent fission product and actinide fluorides' volatilities and reaction temperatures with NF3 at which volatile fluorides form can be exploited to provide desired separations. This paper supplements our previously reported results on constituents that can form volatile fluorides or oxyfluorides with results on constituents that should not form volatile fluorides or oxyfluorides. Cumulatively, our studies showed that rates of reaction of surrogate fuel constituent, cobalt, and the higher non-fission product lanthanide oxides with NF3 are highly temperature sensitive and depend significantly on the element with the higher lanthanides proving to be the most resistant to reaction. The thermodynamic calculations showed that NF3 should completely fluorinate the tested transition metal and lanthanide oxides to their fluorides. Simultaneous thermogravimetric and differential thermal analyses showed that NF3 converts the oxides of cobalt, zirconium, yttrium, and the lanthanides to non-volatile fluorides or oxyfluorides up to 550 degrees C and most importantly can extract the volatile fluoride-forming uranium, the bulk constituent in used nuclear fuel, from the non-volatile fluoride forming gadolinium. Overall these investigations demonstrate that NF3 can fluorinate used nuclear fuel constituent oxides, cobalt (II) oxide, and higher lanthanide oxides but with an effectiveness depending on the constituent metal.

CA CDF Collaboration TI Search for the Higgs boson in the all-hadronic final state using the full CDF data set SO JOURNAL OF HIGH ENERGY PHYSICS LA English DT Article DE Hadron-Hadron Scattering ID STANDARD MODEL; P(P)OVER-BAR COLLISIONS; BROKEN SYMMETRIES; TEV; DETECTOR; EVENTS; MASS; LHC AB This paper reports the result a search for the standard model Higgs boson in events containing four reconstructed jets associated with quarks. For masses below 135 GeV/c(2), the Higgs boson decays to bottom-antibottom quark pairs are dominant and result primarily in two hadronic jets. An additional two jets can be produced in the hadronic decay of a W or Z boson produced in association with the Higgs boson, or from the incoming quarks that produced the Higgs boson through the vector-boson fusion process. The search is performed using a sample of root s = 1.96.TeV proton-antiproton collisions corresponding to an integrated luminosity of 9.45 fb(-1) recorded by the CDF II detector. The data are in agreement with the background model and 95% credibility level upper limits on Higgs boson production are set as a function of the Higgs boson mass. The median expected (observed) limit for a 125 GeV/c(2) Higgs boson is 11.0 (9.0) times the predicted standard model rate. C1 [Chen, Y. C.; Hou, S.; Mitra, A.; Teng, P. K.; Wang, S.

CA ZEUS Collaboration TI Measurement of inelastic J/psi and psi ' photoproduction at HERA SO JOURNAL OF HIGH ENERGY PHYSICS LA English DT Article DE Lepton-Nucleon Scattering; QCD ID CENTRAL TRACKING DETECTOR; ZEUS BARREL CALORIMETER; HEAVY-QUARK PRODUCTION; DESIGN; ENERGY; QCD; CONSTRUCTION; SYSTEM; K(T)-FACTORIZATION; PERFORMANCE AB The cross sections for inelastic photoproduction of J/psi, and psi' mesons have been measured in ep collisions with the ZEUS detector at HERA, using an integrated luminosity of 468 pb(-1) collected in the period 1996-2007. The psi' to J/psi cross section ratio was measured in the range 0.55 < z < 0.9 and 60 < W < 190 GeV as a function of W, z and p(T). Here W denotes the photon-proton centre-of-mass energy, z is the fraction of the incident photon energy carried by the meson and p(T) is the transverse momentum of the meson with respect to the beam axis. The J/psi cross sections were measured for 0.1 < z < 0.9, 60 < W < 240 GeV and p(T) > 1 GeV. Theoretical predictions within the non-relativistic QCD framework including NLO colour-singlet and colour-octet contributions were compared to the data, as were predictions based on the k(T)-factorisation approach.
