TI Thermally-induced structural and chemical alteration of organic-walled microfossils: an experimental approach to understanding fossil preservation in metasediments SO GEOBIOLOGY LA English DT Article ID RAMAN SPECTROSCOPY COMMUNICATION; EARTHS EARLIEST FOSSILS; CARBONACEOUS MATERIAL; METAMORPHIC ROCKS; BURGESS-SHALE; SOUTH-AFRICA; WESTERN-AUSTRALIA; SOLID BITUMENS; HIGH-PRESSURE; RUYANG GROUP AB The identification and confirmation of bona fide ArcheanPaleoproterozoic microfossils can prove to be a challenging task, further compounded by diagenetic and metamorphic histories. While structures of likely biological origin are not uncommon in Precambrian rocks, the search for early fossil life has been disproportionately focused on lesser thermally altered rocks, typically greenschist or lower-grade metamorphism. Recently, however, an increasing number of inferred micro- and macrofossils have been reported from higher-grade metasediments, prompting us to experimentally test and quantify the preservability of organic-walled microfossils over varying durations of controlled heating and under two differing redox conditions. Because of their relatively low-intensity natural thermal alteration, acritarchs from the Mesoproterozoic Ruyang Group were chosen as subjects for experimental heating at approximately 500 degrees C, with durations ranging from 1 to 250 days and in both oxic (normal present day conditions) and anoxic conditions. Upon extraction, the opacity, reflectivity, color, microchemistry, and microstructures of the heated acritarchs were characterized using optic microscopy, scanning electron microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy. The results differ for acritarchs prepared under oxic vs. anoxic conditions, with the anoxic replicates surviving experimental heating longer and retaining biological morphologies better, despite an increasing degree of carbonization with continuous heating. Conversely, the oxic replicates show aggressive degradation. In conjunction with fossils from high-grade metasediments, our data illustrate the preservational potential of organic-walled microfossils subjected to metamorphism in reducing conditions, offer insights into the search for microfossils in metasediments, and help to elucidate the influence of time on the carbonization/graphitization processes during thermal alteration.

Participants were 43 persons, most with normal cognition or mild cognitive impairment. Vascular risk was quantified using the Framingham Coronary Risk Profile (FCRP) score. Cerebral amyloid was measured by [C-11] Pittsburgh compound B (PIB) positron emission tomography (PET) and quantified with a Global PIB index, which is the average of distribution volume ratios in selected cortical regions of interest. In a bivariate model FCRP accounted for 16% of the variance in PIB index (p < 0.008) and the positive association remained significant controlling for age and sex. The effect of FCRP was independent of apolipoprotein E (APOE) genotype, which was also associated as expected with PIB. Carotid intima-media thickness was not associated with PIB index. Effects of individual FCRP component risk factors, cholesterol, and glycemic status on PIB index were all nonsignificant, suggesting an aggregate effect of risk factors. Although this is a correlational observation it may represent a causal relationship as there are multiple, plausible, amyloidogenic mechanisms of vascular risk factors. Published by Elsevier Inc.

TI ANALYSIS OF BR2 LOSS-OF-FLOW TESTS C AND F SO NUCLEAR TECHNOLOGY LA English DT Article DE loss of flow and pressure; flow reversal; natural convection AB To support the safety analysis of the conversion of the BR2 research reactor to low-enriched uranium (LEU) fuel and extend the validation basis of the RELAP code for the analysis of the conversion of research reactors from highly enriched (HEU) fuel to LEU, the simulation of BR2 tests A/400/1, C/600/3, and F/400/1 was undertaken. These tests are characterized by loss of flow initiated at different reactor power levels with or without loss of system pressure, reactor scram, flow reversal, and reactor cooling by natural circulation. This work presents the RELAP analysis of tests C/600/3 and F/400/1 and comparison of code predictions with experimental measurements for peak cladding temperatures during the transient at different axial locations in an instrumented fuel assembly. The simulations show that accurate representation of the power distribution, especially after reactor scram, between the fuel assemblies and the moderator/reflector regions is critical for the correct prediction of the peak cladding temperatures during the transient. Detailed MCNP and ORIGEN simulations were performed to compute the power distribution between the fuel assemblies and the moderator/reflector regions. With these distributions the predicted peak cladding temperatures are in good agreement with experimental measurements.

Parans TI Novel tri-modal defect structure in Nb-doped MOCVD YBa2Cu3O7: a paradigm for pinning landscape control SO SUPERCONDUCTOR SCIENCE & TECHNOLOGY LA English DT Article ID SUPERCONDUCTING PROPERTIES; COATED CONDUCTOR; FILMS AB Immobilization of vortices, or flux pinning, is both an enduring scientific issue and one of the most important problems in optimizing high temperature superconductors (HTSs) for commercial use. Here, we demonstrate a practical approach to the creation of a multi-modal flux pinning landscape in YBa2Cu3O7 (YBCO) films employing an industrially scalable metal-organic chemical vapor deposition technique. Through controlled additions of Nb, we have achieved a novel distribution of crystallographic defects that immobilize (pin) vortices in the YBCO matrix. That is, with only the addition of a single dopant element, a tri-modal, non-superconducting defect structure is induced that threads through the YBCO matrix laterally (parallel to the ab planes of YBCO), vertically (parallel to the YBCO c-axis), and isotropically in the form of random spherical defects. For optimally doped samples, the influence of these multi-modal nanocrystalline defect structures on the flux pinning properties manifests itself as a significant improvement in the critical current density (J(c)) for all magnetic field orientations. The results demonstrate the possibility of achieving an ideal flux pinning landscape (from an orientation and strength viewpoint), which permits the design of HTS wires with fully-tunable properties by processes suitable for large-scale manufacturing.

Based on these models, discharge rates in South and Central Bays were 0.3-7.4 m(3) day(-1) m(-1). Although SGD fluxes at the two regions (Central and South Bays) of SFB were of the same order of magnitude, the dissolved inorganic nitrogen (DIN) species associated with SGD were different. In the South Bay, ammonium (NH (4) (+) ) concentrations in groundwater were three-fold higher than in open bay waters, and NH (4) (+) was the primary DIN form discharged by SGD. At the Central Bay site, the primary DIN form in groundwater and associated discharge was nitrate (NO (3) (-) ). The stable isotope signatures (delta N-15(NO3) and delta O-18(NO3)) of NO (3) (-) in the South Bay groundwater and surface waters were both consistent with NO (3) (-) derived from NH (4) (+) that was isotopically enriched in N-15 by NH (4) (+) volatilization. Based on the calculated SGD fluxes and groundwater nutrient concentrations, nutrient fluxes associated with SGD can account for up to 16 % of DIN and 22 % of DIP in South and Central Bays. The form of DIN contributed to surface waters from SGD may impact the ratio of NO (3) (-) to NH (4) (+) available to phytoplankton with implications to bay productivity, phytoplankton species distribution, and nutrient uptake rates. This assessment of nutrient delivery via groundwater discharge in SFB may provide vital information for future bay ecological wellbeing and sensitivity to future environmental stressors.

TI Measurement and Analytical Modeling of the Deployment Rate of Elastic Memory Composites SO EXPERIMENTAL MECHANICS LA English DT Article DE Elastic memory composites; Shape memory effect; Microbuckling; Experimental setup; Analytical prediction model AB Polymer composites that can be folded into different angles and upon reheating come back to their original shapes are called elastic memory composites (EMC). This is particularly attractive for the development of large deployable space-based sensors which can be stowed during launch and deployed in orbit. However, the dynamics of deployment (rate and precision) is important considering the high levels of positional sensitivity of such structures. The rate of deployment of the composite depends on the viscoelastic properties of the EMC polymer and the elastic properties of the fibers. In this paper first the experimental setup for deployment data acquisition and resin viscoelastic properties is discussed and then an analytical prediction model (based on micro-mechanics) is developed. The analytical model is validated by excellent correlation with the deployment test data. C1 [Azarbayejani, M.] Univ Texas Pan Amer, Dept Civil Engn, Edinburg, TX 78541 USA. [Maji, A.

We provided a rigorous proof that the true growth yield coefficient (YG) is the ratio of the specific maintenance rate (a in Herbert) to the maintenance coefficient (m in Pirt). Other findings from this study include: (1) the Compromise model is identical to the Herbert for computing microbial growth and substrate consumption, but it expresses the dependence of maintenance on both microbial biomass and substrate; (2) the maximum specific growth rate in the Herbert (mu max,H) is higher than those in the other two models (mu max,P and mu max,C), and the difference is the physiological maintenance factor (mq = a); and (3) the overall maintenance coefficient (mT) is more sensitive to mq than to the specific growth rate (mu G) and YG. Our critical reassessment of microbial maintenance provides a new approach for quantifying some important components in soil microbial ecology models.

TI Two-dimensional radiation MHD modeling assessment of designs for argon gas puff distributions for future experiments on the refurbished Z machine SO HIGH ENERGY DENSITY PHYSICS LA English DT Article DE Argon; Gas puff; K-shell; Non-LTE ID Z-PINCH; TRANSPORT; EMISSION AB Argon Z-pinch experiments are to be performed on the refurbished Z machine (which we will refer to as ZR here in order to distinguish between pre-refurbishment Z) at Sandia National Laboratories with a new 8 cm diameter double-annulus gas puff nozzle constructed by Alameda Applied Sciences Corporation (AASC). The gas exits the nozzle from an outer and inner annulus and a central jet. The amount of gas present in each region can be varied. Here a two-dimensional radiation MHO (2DRMHD) model, MACH2-TCRE, with tabular collisional radiative equilibrium atomic kinetics is used to theoretically investigate stability and K-shell emission properties of several measured (interferometry) initial gas distributions emanating from this new nozzle. Of particular interest is to facilitate that the distributions employed in future experiments have stability and K-shell emission properties that are at least as good as the Titan nozzle generated distribution that was successfully fielded in earlier experiments on the Z machine before it underwent refurbishment. The model incorporates a self-consistent calculation for non-local thermodynamic equilibrium kinetics and ray-trace based radiation transport. This level of detail is necessary in order to model opacity effects, non-local radiation effects, and the high temperature state of K-shell emitting Z-pinch loads. Comparisons of radiation properties and stability of measured AASC gas profiles are made with that of the distribution used in the pre-refurbished Z experiments. Based on these comparisons, an optimal K-shell emission producing initial gas distribution is determined from among the AASC nozzle measured distributions and predictions are made for K-shell yields attainable from future ZR experiments.

Radiation transport theory is the framework for calculating radiation output based on atomic kinetics, and is thus critical to designing and diagnosing experiments in which radiation production is significant. Starting in the 1960s, the astrophysics community established benchmarks for computational radiation transport, based on a parameterized two-level-atom, and mostly applicable to media with very high optical depths and low collisional quenching of radiative transitions. The purpose of the work reported here is to establish a similar computational radiation transport benchmark that is more relevant to a laboratory HEDP environment. Our model consists of 8 levels of mostly K-shell Al ions, ranging from the ground state of Li-like Al to its bare nucleus. Rates connecting the levels are given by well-known, readily reproducible analytic prescriptions. The results presented consist of level populations as a function of position within the cylindrical medium, and emitted line profiles. For the plasma conditions considered, the magnitudes and spatial variations of the populations are a sensitive indicator of the accuracy of the radiation transport model, and are critical in calculating experimentally relevant quantities such as radiative powers and line ratios.

The method is based on the recently developed partially resolved transition array model. Numerical examples show that spectrum calculations using the statistical approach are in good agreement with DLA results. In particular, the statistical method conserves systematic line coincidences across transition arrays differing only in the subshell occupation of excited spectator electrons important in opacity calculations. In addition, it is computationally efficient; hence, it can accelerate spectrum calculations without introducing significant uncertainties whenever the DLA method is considered impractical.

TI Atomic physics and ionization balance of high-Z Ions: Critical ingredients for characterizing and understanding high-temperature plasmas SO HIGH ENERGY DENSITY PHYSICS LA English DT Article DE Ionization balance; Highly charged ions; Gold plasma ID CHARGE-STATE DISTRIBUTION; OPTICALLY THIN PLASMAS; CORONAL AU PLASMA; DIELECTRONIC RECOMBINATION; RATE COEFFICIENTS; TOKAMAK PLASMAS; EBIT DATA; EQUILIBRIUM; BEAM; SPECTROMETER AB A correct description of the ionization balance of high-Z ions, i.e., the fractional abundance of different charge states of a particular element, is critical for interpreting diagnostic line ratios, for describing radiation flow within and out of the plasma, and for assessing the energy balance of high-temperature plasmas. Despite the fundamental nature of this atomic physics parameter, the ionization balance as a function of plasma electron density and electron temperature is generally rather poorly known both experimentally and theoretically. This is the case irregardless of the type of plasma, i.e., low-density astrophysical and coronal plasmas, intermediate density magnetically confined fusion plasmas, or high energy density (HED) laboratory plasmas. We illustrate these points by reviewing existing measurements of the ionization balance of high-Z elements in high-temperature plasmas and discussing the difficulties associated with ionization balance calculations. We focus on the two high-Z elements tungsten (Z = 74) and gold (Z = 79), which play important roles in magnetic fusion and HED plasmas and for which we present calculations of the ionization energies for each charge state. We show that the accuracy of the treatment of dielectronic recombination is currently a limiting factor in proper modeling of the ionization balance and propose "differential" measurements that determine the amount of dielectronic recombination concurrently with the ionization balance as the next step for advancing ionization balance modeling. As an example of the differential measurement approach, we present recent experiments carried out at the Livermore electron beam ion trap, which investigated the ionization balance of gold in the presence of beam-resonant dielectronic recombination. These plasmas limit the immense complexity of dielectronic recombination resonances so that both approximate and reasonably complete detailed calculations can be compared to the measurements. This represents a path forward for constructing and selecting those approximations that produce the most reliable ionization balance models. (C) 2012 Elsevier B.V. All rights reserved.

Significant X-ray emissions in the K-shell from moderately high atomic number plasmas such as Cu generate extreme interest. However, the production of these hard photons from high Z materials comes with a price. There is substantial loss of radiative yield due to stripping through many electrons present in high Z materials to reach to the H- or He-like ionization stages. Production of hard X-rays for materials with atomic number higher than Cu such as Kr is very difficult and theoretical predictions are even more uncertain. Previous experimental efforts using Cu as a plasma pinch load are encouraging and promote further investigations of this element on the refurbished Z machine for achieving photon energies higher than 5 keV and obtaining sufficient radiative yield. We will analyze the ionization dynamics and generate Cu spectrum using the temperature and density conditions obtained from 1-D non-LTE radiation hydrodynamics simulations of Cu wire array implosions on ZR. These results will be compared with K- and L-shell experimental spectrum of shot Z 1975. Theoretical K- and L-shell spectroscopy provides validation of atomic and plasma modeling when compared to available experimental data and also provides useful diagnostics for the plasma parameters. Our self-consistently generated non-LTE collisional-radiative model employs an extensive atomic level structure and data for all dominant atomic processes that are necessary to model accurately the pinch dynamics and the spectroscopic details of the emitted radiation.

The thickness of the foils (d similar to 30 nm) is roughly one-third of the ballistic electron transport range at ambient conditions (similar to 100 nm). At lower pump fluences, the front and back sides of the foil behave similarly, indicating uniform heating by ballistic electrons. As the pump fluence is increased, the phase shift on the front side is higher than that on the back, indicating a significant reduction in the ballistic electron transport range.

TI Striatal Dopamine Influences the Default Mode Network to Affect Shifting between Object Features SO JOURNAL OF COGNITIVE NEUROSCIENCE LA English DT Article ID CARD SORTING TEST; TASK-INDUCED DEACTIVATION; HUMAN PREFRONTAL CORTEX; PARKINSONS-DISEASE; WORKING-MEMORY; BASAL GANGLIA; FUNCTIONAL CONNECTIVITY; NEUROPSYCHOLOGICAL PERFORMANCE; PHENYLALANINE DEPLETION; COGNITIVE FLEXIBILITY AB Cognitive flexibility or the ability to change behavior in response to external cues is conceptualized as two processes: one for shifting between perceptual features of objects and another for shifting between the abstract rules governing the selection of these objects. Object and rule shifts are believed to engage distinct anatomical structures and functional processes. Dopamine activity has been associated with cognitive flexibility, but patients with dopaminergic deficits are not impaired on all tasks assessing cognitive flexibility, suggesting that dopamine may have different roles in the shifting of objects and rules. The goals of this study were to identify brain regions supporting object and rule shifts and to examine the role of dopamine in modulating these two forms of cognitive flexibility. Sixteen young, healthy volunteers underwent fMRI while performing a set-shift task designed to differentiate shifting between object features from shifting between abstract task rules. Participants also underwent PET with 6-[F-18]-fluoro-L-m-tyrosine (FMT), a radiotracer measuring dopamine synthesis capacity. Shifts of abstract rules were not associated with activation in any brain region, and FMT uptake did not correlate with rule shift performance. Shifting between object features deactivated the medial PFC and the posterior cingulate and activated the lateral PFC, posterior parietal areas, and the striatum. FMT signal in the striatum correlated negatively with object shift performance and deactivation in the medial PFC, a component of the default mode network, suggesting that dopamine influences object shifts via modulation of activity in the default mode network.

It is shown that owing to the large transverse current generated by field ionization with few-cycle laser pulses, strong THz emission can be generated. The change of the carrier phase of the few-cycle laser pulses leads to the variation of the ionization currents. Correspondingly, the THz emission amplitude shows the characteristic as a periodic function of the carrier phase, which is also confirmed by one-dimensional particle-in-cell simulations. For a given carrier phase, the THz emission amplitude is not proportional to the laser amplitude. It shows at least two peaks at certain laser amplitudes. When the gas density profile is not uniform, the emission amplitude has a similar dependence on laser amplitude and carrier envelope phase, but the THz pulse duration and spectrum are quite different.

This paper uses several well-known energy system and electricity models to analyze a CES that reflects broad principles outlined in President Obama's January 2011 State of the Union Address and in the Administration's subsequent Blueprint for a Secure Energy Future.(1) In particular it examines three different design options for a CES that would each lead to approximately 80% clean electricity by 2035. These different design options provide broadly similar economic incentives for clean energy deployment and yield similar overall welfare impacts, but they exhibit different distributional outcomes. The most inclusive CES crediting approach favors producers over consumers in competitive electricity markets as well as regions with larger initial endowments of clean energy On the other hand, the most restrictive crediting approach favors consumers over producers and reduces preferences for regions with larger initial endowments of clean energy. While specific technology outcomes vary across the four models used in this study, key insights about cost-effectiveness and economic incidence are largely robust to the underlying modeling platform. These insights may be important considerations in future CES policy design efforts.

A directload control algorithm is presented. A temperature-priority-list method is used to dispatch the HVAC loads optimally to maintain customer-desired indoor temperatures and load diversity. Realistic intra-hour load balancing signals are used to evaluate the operational characteristics of the HVAC load under different outdoor temperature profiles and different indoor temperature settings. The number of HVAC units needed is also investigated. Modeling results suggest that the number of HVAC units needed to provide a +/- 1-MW load balancing service 24 hours a day varies significantly with baseline settings, high and low temperature settings, and outdoor temperatures. The results demonstrate that the intra-hour load balancing service provided by HVAC loads meets the performance requirements and can become a major source of revenue for load-serving entities where the two-way communication smart grid infrastructure enables direct load control over the HVAC loads.

TI PMU-Based Wide-Area Security Assessment: Concept, Method, and Implementation SO IEEE TRANSACTIONS ON SMART GRID LA English DT Article DE Operating transfer capability; real time security assessment; security margin; wide-area dynamic security region ID POWER-SYSTEMS; REGIONS AB This paper presents a concept, method, and implementation of utilizing phasor measurement unit (PMU) information to monitor the wide-area security of a power system. The close dependency of major transmission paths requires an approach that takes that interaction into account while establishing operational transfer capability, and evaluates grid reliability and security on a system-wide basis. Thus, the concept of wide-area security region, which considers all essential constraints, including thermal, voltage stability, transient stability, and small signal stability, is proposed. This approach expands the idea of traditional transmission system nomograms to a multidimensional case, involving multiple system limits and parameters such as transmission path constraints, zonal generation or load, etc., considered concurrently. In this paper, the security region boundary is represented using piece-wise approximation with the help of linear inequalities (so called hyperplanes) in a multidimensional space, consisting of system parameters that are critical for security analysis. The goal of this approximation is to find a minimum set of hyperplanes that describe the boundary with a given accuracy. Offline computer simulations are conducted to build the security region and the hyperplanes can be applied in real time with phasor information for on-line security assessment. Numerical simulations have been performed for the full size Western Electricity Coordinating Council (WECC) system model, which comprises 15 126 buses and 3034 generators. Simulation results demonstrated the feasibility and effectiveness of this approach, and proved that the proposed approach can significantly enhance the wide-area situation awareness for a bulk power system like WECC.

Secreted mucins, produced by goblet cells and the gastric mucosa, provide the scaffold for a micrometers-thick mucus layer that lines the epithelia of the gut and respiratory tract(3,4). In addition to mucins, mucus layers also contain antimicrobial peptides, cytokines, and immunoglobulins(5-9). The mucus layer is an important part of host innate immunity, and forms the first line of defense against invading microorganisms(8,10-12). As such, the mucus is subject to numerous interactions with microbes, both pathogens and symbionts, and secreted mucins form an important interface for these interactions. The study of such biological interactions usually involves histological methods for tissue collection and staining. The two most commonly used histological methods for tissue collection and preservation in the clinic and in research laboratories are: formalin fixation followed by paraffin embedding, and tissue freezing, followed by embedding in cryo-protectant media. Paraffin-embedded tissue samples produce sections with optimal qualities for histological visualization including clarity and well-defined morphology. However, during the paraffin embedding process a number of epitopes become altered and in order to study these epitopes, tissue sections have to be further processed with one of many epitope retrieval methods(13). Secreted mucins and lipids are extracted from the tissue during the paraffin-embedding clearing step, which requires prolong incubation with organic solvents (xylene or Citrisolv). Therefore this approach is sub-optimal for studies focusing on the nature and distribution of mucins and mucus in vivo. In contrast, freezing tissues in Optimal Cutting Temperature (OCT) embedding medium avoids dehydration and clearing of the sample, and maintains the sample hydration. This allows for better preservation of the hydrated mucus layer, and thus permits the study of the numerous roles of mucins in epithelial biology. As this method requires minimal processing of the tissue, the tissue is preserved in a more natural state. Therefore frozen tissues sections do not require any additional processing prior to staining and can be readily analyzed using immunohistochemistry methods. We demonstrate the preservation of micrometers-thick secreted mucus layer in frozen colon samples. This layer is drastically reduced when the same tissues are embedded in paraffin. We also demonstrate immunofluorescence staining of glycan epitopes presented on mucins using plant lectins. The advantage of this approach is that it does not require the use of special fixatives and allows utilizing frozen tissues that may already be preserved in the laboratory.

This was done by simultaneously analyzing small angle neutron and X-ray scattering data, with the constraint of measured lipid volumes. We report the temperature dependence of bilayer parameters obtained using the one-dimensional scattering density profile model which was derived from molecular dynamics simulations - including the area per lipid, the overall bilayer thickness, as well as other intrabilayer parameters (e.g., hydrocarbon thickness). Lipid areas are found to be larger than their phosphatidylcholine (PC) counterparts, a result likely due to repulsive electrostatic interactions taking place between the charged PG headgroups even in the presence of sodium counterions. In general, PG and PC bilayers show a similar response to changes in temperature and chain length, but differ in their response to chain unsaturation. For example, compared to PC bilayers, the inclusion of a first double bond in PG lipids results in a smaller incremental change to the area per lipid and bilayer thickness. However, the extrapolated lipid area of saturated PG lipids to infinite chain length is found to be similar to that of PCs, an indication of the glycerol-carbonyl backbone's pivotal role in influencing the lipid-water interface.

The study incorporates satellite imagery, fracture detection and shear wave anisotropy logs and 3D seismic to identify potential issues that could impact long term reservoir integrity, CO2 flow and retention. The properties of fracture networks within the reservoir and sealing strata are important to understand in carbon sequestration and enhanced recovery efforts. Fracture networks exert significant control on the ability of a reservoir to retain CO2 for long (thousand year) time frames with minimal leakage. Local structural complexity at the pilot site resulted in tracer migration patterns that differed from predictions based on regional descriptions of fracture and cleat orientations measured in areas several miles from the site. Perfluorocarbon (PFC) tracer breakthrough in the production stream of nearby producing wells, for example, occurred first in a well to the east, in a direction close to the presumed butt cleat trend rather than in a well at equal distance along what had been assumed to be the more permeable face cleat trend. The study reveals local tectonic complexity not suggested by well log derived structure maps of the area and suggests that fractures and faults disrupt the local Fruitland coal reservoir and the overlying Kirtland Shale primary seal.

TI Estimating alarm thresholds and the number of components in mixture distributions SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Mixture fitting; Nuclear safeguards; Solution monitoring AB Mixtures of probability distributions arise in many nuclear assay and forensic applications, including nuclear weapon detection, neutron multiplicity counting, and in solution monitoring (SM) for nuclear safeguards. SM data is increasingly used to enhance nuclear safeguards in aqueous reprocessing facilities having plutonium in solution form in many tanks. This paper provides background for mixture probability distributions and then focuses on mixtures arising in SM data. SM data can be analyzed by evaluating transfer-mode residuals defined as tank-to-tank transfer differences, and wait-mode residuals defined as changes during non-transfer modes. A previous paper investigated impacts on transfer-mode and wait-mode residuals of event marking errors which arise when the estimated start and/or stop,times of tank events such as transfers are somewhat different from the true start and/or stop times. Event marking errors contribute to non-Gaussian behavior and larger variation than predicted on the basis of individual tank calibration studies. This paper illustrates evidence for mixture probability distributions arising from such event marking errors and from effects such as condensation or evaporation during non-transfer modes, and pump carryover during transfer modes. A quantitative assessment of the sample size required to adequately characterize a mixture probability distribution arising in any context is included. (C) 2012 Elsevier B.V. All rights reserved.

To achieve this goal, the collaboration will build eight functionally identical antineutrino detectors. The first two detectors have been constructed, installed and commissioned in Experimental Hall 1, with steady data-taking beginning September 23, 2011. A comparison of the data collected over the subsequent three months indicates that the detectors are functionally identical, and that detector-related systematic uncertainties are smaller than requirements.

An important question is the extent to which the mixing of Columbia River water and groundwater impacts the speciation and mobility of uranium (U). In this study, we designed experiments to mimic interactions among U, oxic groundwater or Columbia River water, and 300 A sediments in the subsurface environment of Hanford 300 A. The goals were to investigate mechanisms of: 1) U immobilization in 300 A sediments under bulk oxic conditions and 2) U remobilization from U-immobilized 300 A sediments exposed to oxic Columbia River water. Initially, 300 A sediments in column reactors were fed with U(VI)containing oxic 1) synthetic groundwater (SGW), 2) organic-amended SGW (OA-SGW), and 3) de-ionized (DI) water to investigate U immobilization processes. After that, the sediments were exposed to oxic Columbia River water for U remobilization studies. The results reveal that U was immobilized by 300 A sediments predominantly through reduction (80-85%) when the column reactor was fed with oxic OA-SGW. However, U was immobilized by 300 A sediments through adsorption (100%) when the column reactors were fed with oxic SGW or DI water. The reduced U in the 300 A sediments fed with OASGW was relatively resistant to remobilization by oxic Columbia River water. Oxic Columbia River water resulted in U remobilization (similar to 7%) through desorption, and most of the U that remained in the 300 A sediments fed with OA-SGW (similar to 93%) was in the form of uraninite nanoparticles. These results reveal that: 1) the reductive immobilization of U through OA-SGW stimulation of indigenous 300 A sediment microorganisms may be viable in the relatively oxic Hanford 300 A subsurface environments and 2) with the intrusion of Columbia River water, desorption may be the primary process resulting in U remobilization from OA-SGW-stimulated 300 A sediments at the subsurface of the Hanford 300 A site.

A technique based on 454 sequencing of a library highly enriched for microsatellite repeats was used to develop loci for Nasua narica. Twenty-four polymorphic microsatellites were developed and tested as markers in the target species. All markers were genotyped on 18 different individuals from three distinct locations. We observed medium to low genetic variation across most loci (mean number of alleles per locus = 5). Levels of expected heterozygosity across all markers was fairly low (mean H-E = 0.326, range 0.05-0.49).

TI Evaluating bounds and estimators for constants of random polycrystals composed of orthotropic elastic materials SO INTERNATIONAL JOURNAL OF ENGINEERING SCIENCE LA English DT Article DE Elasticity; Polycrystals; Bounds and estimates ID HASHIN-SHTRIKMAN BOUNDS; TETRAGONAL SYMMETRIES; MODULI; CRYSTALS; MODEL AB While the well-known Voigt and Reuss (VR) bounds, and the Voigt-Reuss-Hill (VRH) elastic constant estimators for random polycrystals are all straightforwardly calculated once the elastic constants of anisotropic crystals are known, the Hashin-Shtrikman (HS) bounds and related self-consistent (SC) estimators for the same constants are, by comparison, more difficult to compute. Recent work has shown how to simplify (to some extent) these harder to compute HS bounds and SC estimators. An overview and analysis of a subsampling of these results is presented here with the main point being to show whether or not this extra work (i.e., in calculating both the HS bounds and the SC estimates) does provide added value since, in particular, the VRH estimators often do not fall within the HS bounds, while the SC estimators (for good reasons) have always been found to do so. The quantitative differences between the SC and the VRH estimators in the eight cases considered are often quite small however, being on the order of +/- 1%. These quantitative results hold true even though these polycrystal Voigt-Reuss-Hill estimators more typically (but not always) fall outside the Hashin-Shtrikman bounds, while the self-consistent estimators always fall inside (or on the boundaries of) these same bounds.

The test tube, made of copper, with outer diameter of 7.94 mm, was uniformly heated ohmically by high electric current through a transformer. The tests were conducted at mass and heat fluxes, ranging from 100 to 250 kg m(-2) s(-1) and 10-25 kW m(-2), respectively. The new experimental data from these tests for varying conditions is provided in Appendix 1 for future research. The experimental data shows that h(tp) increases with vapour quality until dryout, and decreases with saturation temperature, while heat flux has more pronounced effect on htp, suggesting the dominance of nucleate boiling. Furthermore, predictions from several empirical correlations disagree with the current CO2 experimental data in the micro-fin tube. [11] and [4] correlations predict with deviations of up to +/- 50%.

TI In-situ imaging of the nucleation and growth of epitaxial anatase TiO2(001) films on SrTiO3(001) SO SURFACE SCIENCE LA English DT Article DE Anatase; TiO2; MBE; STM; RHEED; SrTiO3 ID MOLECULAR-BEAM EPITAXY; TIO2 THIN-FILMS; SURFACE; SUBSTRATE; LAALO3; DEPOSITION; TIO2(110); MOBILITY; LAYERS; CELL AB The growth of TiO2 anatase films on Nb-doped SrTiO3(001) molecular beam epitaxy has been studied in-situ by scanning tunneling microscopy. We show that the initial growth follows the Stranski-Krastanov mode, where islands form on top of a wetting layer consisting of two monolayers (ML) of TiO2. The epitaxial islands subsequently nucleate and coalesce into large commonly oriented crystallites. The reconstruction observed by reflection high-energy electron diffraction (RHEED) is shown to result from the coexistence of individual (4 x 1) and (1 x 4) reconstructions present on different crystallite surfaces. The anatase grows in units of bilayers, resulting in a step height of 2 ML (similar to 0.5 nm). This result explains the fact that the measured period of the RHEED specular-beam intensity oscillations corresponds to the time required for deposition of 2 ML Ar ion sputtering and UHV annealing results in a transformation to coexisting (4 x 1) and (1 x 4) reconstructed terraces on individual crystallites, as commonly observed by ex-situ STM studies.

Traditional analysis and visualization techniques rely primarily on computing streamlines through numerical integration. The inherent numerical errors of such approaches are usually ignored, leading to inconsistencies that cause unreliable visualizations and can ultimately prevent in-depth analysis. We propose a new representation for vector fields on surfaces that replaces numerical integration through triangles with maps from the triangle boundaries to themselves. This representation, called edge maps, permits a concise description of flow behaviors and is equivalent to computing all possible streamlines at a user defined error threshold. Independent of this error streamlines computed using edge maps are guaranteed to be consistent up to floating point precision, enabling the stable extraction of features such as the topological skeleton. Furthermore, our representation explicitly stores spatial and temporal errors which we use to produce more informative visualizations. This work describes the construction of edge maps, the error quantification, and a refinement procedure to adhere to a user defined error bound. Finally, we introduce new visualizations using the additional information provided by edge maps to indicate the uncertainty involved in computing streamlines and topological structures.

Males that exhibited the typical appearance of late-second-instar nymphs were tested. The male behavior was monitored soon after their exposure to the tested female sex pheromone in glass Petri dish arenas. Male nymph behavior toward the pheromone source was characterized based on their aggregation on the disks in the arena. Males of all four tested mealybug species were attracted to their conspecific female pheromone. By contrast, almost no interceptions of male nymphs with disks impregnated with a heterospecific female pheromone were observed. The mode of attraction of each of male nymphs of P. ficus, among most of the tested individuals (> 80%), to the conspecific female sex pheromone, (S)-lavandulyl senecioate and or (S)-lavandulyl isovalerate, was the same as the mode of attraction latter on as adult. We suggest that by being attracted to the conspecific pheromone these males may direct themselves to a suitable pupation site near conspecific non-sibling mature females, thus preventing inbreeding. The repellency of heterospecific sex pheromone to males that are looking for a pupation site suggests that the latter try to avoid close contact with heterospecific females.

Marian, Jaime TI Techniques to accelerate convergence of stress-controlled molecular dynamics simulations of dislocation motion SO COMPUTATIONAL MATERIALS SCIENCE LA English DT Article DE Screw dislocation; Molecular dynamics; Tungsten; Mobility; Stress ID SCREW DISLOCATIONS; CORE STRUCTURE; GLIDE AB Dislocation mobility -the relation between applied stress and dislocation velocity-is an important property to model the mechanical behavior of structural materials. These mobilities reflect the interaction between the dislocation core and the host lattice and, thus, atomistic resolution is required to capture its details. Because the mobility function is multiparametric, its computation is often highly demanding in terms of computational requirements. Optimizing how tractions are applied can be greatly advantageous in accelerating convergence and reducing the overall computational cost of the simulations. In this paper we perform molecular dynamics simulations of 1/2 < 111 > screw dislocation motion in tungsten using step and linear time functions for applying external stress. We find that linear functions over time scales of the order of 10-20 ps reduce fluctuations and speed up convergence to the steady-state velocity value by up to a factor of two. (C) 2012 Elsevier B.

Compared to stainless steel (SS) positive cans, aluminum (Al)-clad SS-316 positive cans are much more resistant to oxidation at high voltages; therefore, the initial Coulombic efficiency of the batteries with Al-clad can is improved by more than 13%. Among the five separators studied in this work, the polyethylene (PE) separator exhibits the best electrochemical stability. The cells using LiCr0.05Ni0.45Mn1.5O4 as the cathode, an Al-clad positive can, and a PE separator exhibits a first-cycle Coulombic efficiency of about 90% and a capacity fading of only 0.01% per cycle.

The morphology, structure, and activity toward the oxygen reduction reaction (ORR) in alkaline media were evaluated for each electrocatalyst by transmission electron microscopy (TEM), X-ray Diffraction (XRD), and the rotating ring-disk electrode (RRDE) method. Although the Cu-N-x/C catalyst showed lower catalytic activity than Fe-N-x/C, the presence of Cu enhanced the ORR performance of bi-core CuFe-N-x/C, as compared to single-core Fe-N-x/C. To fully understand the synergistic effect between Cu and Fe on this enhancement, high resolution X-ray photoelectron spectroscopy (HR-XPS) and soft X-ray absorption spectroscopy (XAS) was employed to study the electronic structure of as-synthesized electrocatalysts. The HR-XPS analysis showed that metal-nitrogen bonding was maintained and that the oxidation states of Fe and Cu were influenced by the presence of the second metal in the bi-core catalyst. The XAS data revealed that a fraction of an electron was transferred from Fe to Cu, which may help to lower the kinetic barrier during the ORR process. Based on our experimental results and four different models, we briefly discuss ORR mechanisms on these metallic catalysts. Published by Elsevier B.V.

The stability of conventional carbonate electrolytes is strongly related to the stability and properties of the cathode materials in the de-lithiated state. This is the first time report that the conventional electrolytes based on mixtures of EC and linear carbonate (DMC, EMC and DEC) can be cycled up to 5.2 V on LiNi0.45Cr0.05Mn1.5O4 for long-term cycling, where their performances are similar. The discharge capacity increases with the charging cutoff voltage and reaches the highest discharge capacity at 5.2 V. The capacity retention is about 87% after 500 cycles at 1C rate for all three carbonate mixtures in half-cells when cycled between 3.0 V and 5.2 V. When cycled to 5.3 V. EC-DMC still shows good cycling performance but EC-EMC and EC-DEC show faster capacity fading. EC-DMC and EC-EMC have much better rate capability than EC-DEC. The first-cycle irreversible capacity loss increases with the cutoff voltage. The "inactive" conductive carbon is also partly associated with the low first-cycle Coulombic efficiency at high voltages due to electrolyte decomposition and possible PF6- anion irreversible intercalation.

TI FX-RLS-Based Feedforward Control for LIDAR-Enabled Wind Turbine Load Mitigation SO IEEE TRANSACTIONS ON CONTROL SYSTEMS TECHNOLOGY LA English DT Article DE Adaptive control; feedforward control; filtered-x recursive least squares (FX-RLS); light detection and ranging (LIDAR); wind turbine; zero-phase-error tracking control (ZPETC) AB An adaptive feedforward controller based on a filtered-x recursive least square (FX-RLS) algorithm and a non-adaptive feedforward controller based on a zero-phase-error tracking control (ZPETC) technique have been designed to augment a collective pitch proportional-integral (PI) feedback controller for wind turbine rotor speed regulation and component load reduction when the wind turbine is operating above rated wind speed. The inputs to the adaptive feedforward controller include measurements of the rotor speed error and the incoming wind speed, where wind speed would be provided by a commercial light detection and ranging (LIDAR) system. Simulation results are based on comparison with a PI feedback only controller. Simulations show that augmenting the baseline PI feedback control with ZPETC feedforward control improves the blade loads but worsens the tower loads. The FX-RLS feedforward algorithm gives better performance than both the baseline PI feedback and the ZPETC feedforward in both tower (fore-aft and side-to-side) and blade (flapwise and edgewise) bending moment mitigation. Even with realistic 1 Hz LIDAR data update rate, the FX-RLS feedforward strategy can effectively mitigate the tower and blade bending moment while providing better rotor speed tracking and only a small energy drop.

TI Hydrogen responses of ultrathin Pd films and nanowire networks with a Ti buffer layer SO JOURNAL OF MATERIALS SCIENCE LA English DT Article ID ADHESION LAYERS; GAS-DETECTION; THIN-FILMS; PALLADIUM; PERFORMANCE; CHROMIUM; ALLOYS AB We report on hydrogen responses of ultrathin films and nanowire networks of palladium on titanium buffered silicon substrates and filtration membranes, respectively. We found that in both systems signatures such as retarding responses and saturation of the resistance changes at high hydrogen concentrations associated with the transition from Pd/H solid solution to Pd hydride diminish with decreasing the thickness of the palladium layer from 7 to 2 nm. Our results not only reveal a new way to suppress the phase transition in Pd/H system but also provide an alternative approach to achieve fast and sensitive hydrogen sensors with a wide concentration detection range.

TI Compressibility anomaly in the superconducting material Nb3Al under high pressure SO PHYSICA B-CONDENSED MATTER LA English DT Article DE Binary compounds; Pressure effects; X-ray diffraction; Phase transformations ID STRUCTURAL PHASE-TRANSITION; COLLAPSE AB Nb3Al, which is widely used in high field magnets, was studied under a range of pressures up to 39.5 GPa using diamond anvil cell. The Nb3Al superconductor is structurally stable up to the highest pressure of the present investigation from previous reports. However, an anomaly of the compressibility beyond 19.2 GPa was detected in the pressure versus volume plot. The curve of volume versus pressure shows the existence of a plateau around 18.0 GPa as seen in several other highly correlated electrons systems, The observed pressure-induced isostructural phase transition was accomplished with a volume inclination without any symmetrical change (space group, Wyckoff position). The physical mechanism behind this isostructural phase transition is the interesting issue for further studies. (C) 2012 Elsevier B.V. All rights reserved. C1 [Yu, Z. H.; Li, C.

TI On the potential of ethanol fuel stratification to extend the high load limit in stratified-charge compression-ignition engines SO FUEL LA English DT Article DE HCCI; ethanol; CAI; Pressure-rise rate; Heat-release rate ID PORT INJECTION; AUTO-IGNITION; HCCI ENGINES; COMBUSTION; INHOMOGENEITIES AB A multi-zone model is applied to investigate the potential of ethanol fuel stratification to reduce the problematic high rates of pressure-rise that can occur in homogeneous-charge compression-ignition (HCCI) engines. The model is first validated against published experimental data. Novel techniques for inducing in-cylinder stratification are then identified, that involve exploiting the high latent heat of vaporisation of ethanol to induce thermal stratification. This stratification introduces a range of induction times into the cylinder, leading to a staged combustion event. The impact of water content in the fuel is also investigated. This study finds that ethanol fuel stratification has the potential to provide significant improvements relative to the nominally homogeneous operating condition. Significant reductions in pressure-rise rates are attainable, providing the potential for extending the possible operating regime to higher loads. The trade-off between reduced pressure-rise rate and increased NO emissions is discussed. Mixing the fuel with quantities of water, which has cost and overall energy efficiency advantages, is found to significantly reduce the NO production and slightly accentuate the reductions of pressure-rise rate.

The detailed mechanism for biodiesel developed by Lawrence Livermore National Laboratory (LLNL) was employed as the starting mechanism. The rate constants for the n-heptane and larger alkane subcomponents in the detailed mechanism were first updated. The detailed mechanism was then reduced with direct relation graph (DRG), isomer lumping, and DRG-aided sensitivity analysis (DRGASA), which was improved to achieve a larger extent of reduction. The reduction was performed for pressures from 1 to 100 atm and equivalence ratios from 0.5 to 2 for both extinction and ignition applications. The initial temperatures for ignition were from 700 to 1800 K, covering the compression ignition (CI) engine conditions. Extensive validations were performed against 0-D simulations with the detailed mechanism and experimental data for spatially homogeneous systems, 1-D flames and 3D-turbulent spray combustion. The skeletal mechanism was able to predict various combustion characteristics accurately such as ignition delay, flame lift-off length, and equivalence ratio at flame lift-off location under different ambient conditions. Compared with the detailed mechanism that consists of 3299 species and 10806 reactions, the skeletal mechanism features a reduction by a factor of around 30 in size while still retaining good accuracy and comprehensiveness.

The grain size of the processed bulk composite materials is controlled below 20 nm. The refinement of the nanoscale morphology leads to effective inter-phase exchange coupling that results in single-phase like magnetic properties. Energy product of 14 MGOe was obtained in the isotropic nanocomposite magnets at room temperature. At elevated temperatures, the hybrid magnets have greatly improved thermal stability compared to the Nd2Fe14B single-phase counterpart and have substantially increased magnetization and energy products compared to the single-phase SmCo5 counterpart.

TI A 200 degrees C Universal Gate Driver Integrated Circuit for Extreme Environment Applications SO IEEE TRANSACTIONS ON POWER ELECTRONICS LA English DT Article DE Gate driver; high-temperature; silicon-on-insulator (SOI); temperature sensor ID HIGH-TEMPERATURE ELECTRONICS; HYBRID ELECTRIC VEHICLES; DC-DC CONVERTER; CMOS; TRANSISTORS; SENSOR AB High-temperature power converters (dc-dc, dc-ac, etc.) have enormous potential in extreme environment applications, including automotive, aerospace, geothermal, nuclear, and well logging. For successful realization of such high-temperature power conversion modules, the associated control electronics also need to perform at high temperature. This paper presents a silicon-on-insulator (SOI) based high-temperature gate driver integrated circuit (IC) incorporating an on-chip low-power temperature sensor and demonstrating an improved peak output current drive over our previously reported work. This driver IC has been primarily designed for automotive applications, where the underhood temperature can reach 200 degrees C. This new gate driver prototype has been designed and implemented in a 0.8 mu m, 2-poly, and 3-metal bipolar CMOS-DMOS (Double-Diffused Metal-Oxide Semiconductor) on SOI process and has been successfully tested for up to 200 degrees C ambient temperature driving a SiC MOSFET and a SiC normally-ON JFET. The salient feature of the proposed universal gate driver is its ability to drive power switches over a wide range of gate turn-ON voltages such as MOSFET (0 to 20V), normally-OFF JFET (-7 to 3V), and normally-ON JFET (-20 to 0V). The measured peak output current capability of the driver is around 5A and is thus capable of driving several power switches connected in parallel. An ultralow-power on-chip temperature supervisory circuit has also been integrated into the die to safeguard the driver circuit against excessive die temperature (>= 220 degrees C). This approach utilizes increased diode leakage current at higher temperature to monitor the die temperature. The power consumption of the proposed temperature sensor circuit is below 10 mu W for operating temperature up to 200 degrees C. C1 [Huque, Mohammad A.] Elect Power Res Inst, Knoxville, TN 37932 USA.

Solution calorimetry was used to measure the following standard molar enthalpies of solution at T = 298.15 K: Delta H-sol(m)degrees = (12.10 +/- 0.12) kJ . mol(-1) for alpha-D-xylose(cr); Delta H-sol(m)degrees = -(8.1 +/- 2.7) kJ . mol(-1) for 1,4-beta-D-xylobiose(am); and Delta H-sol(m)degrees = -(24.1 +/- 6.4) kJ . mol(-1) for 1,4-beta-D-xylotriose(am). It was observed that both 1,4-beta-D-xylobiose(am) and 1,4-beta-D-xylotriose(am) were amorphous substances and that they form thick gels in water in which no solid phase is present. Consequently, it is not possible to measure m(sat) for these two substances. All substances were carefully characterized by using both HPLC and Karl Fischer analysis. NMR was used to measure the anomeric purity of the alpha-D-xylose(cr). Thermodynamic network calculations were used to calculate standard molar formation properties for the aforementioned substances.

This can be seen in nuclear reactor analysis where analysts are interested in coupled flow, heat transfer and neutronics, and in nuclear fuel performance simulation where analysts are interested in thermomechanics with contact coupled to species transport and chemistry. In energy and environmental applications, energy extraction involves geomechanics, flow through porous media and fractured formations, adding heat transport for enhanced oil recovery and geothermal applications, and adding reactive transport in the case of applications modeling the underground flow of contaminants. These more ambitious simulations usually motivate some level of parallel computing. Many of the physics coupling efforts to date utilize simple code coupling or first-order operator splitting, often referred to as loose coupling. While these approaches can produce answers, they usually leave questions of accuracy and stability unanswered. Additionally, the different physics often reside on distinct meshes and data are coupled via simple interpolation, again leaving open questions of stability and accuracy. This paper is the first part of a two part sequence on multiphysics algorithms and software. Part I examines the importance of accurate time and space integration and that the degree of coupling used for the solution should match the requirements of the simulation. It then discusses the preconditioned Jacobian-free Newton Krylov solution algorithm that is used for both multiphysics and multiscale solutions. Part II [1] presents the software framework; the Multiphysics Object Oriented Simulation Environment (MOOSE) and discusses applications based on it.

The first [1] focused on the algorithms; this part treats the multiphysics software framework and applications based on it. Tight coupling is typically designed into the analysis application at inception, as such an application is strongly tied to a composite nonlinear solver that arrives at the final solution by treating all equations simultaneously. The application must also take care to minimize both time and space error between the physics, particularly if more than one mesh representation is needed in the solution process. This paper presents an application framework that was specifically designed to support tightly coupled multiphysics analysis. The Multiphysics Object Oriented Simulation Environment (MOOSE) is based on the Jacobian-freeNewton-Krylov (JFNK) method combined with physics-based preconditioning to provide the underlying mathematical structure for applications. The report concludes with the presentation of a host of nuclear, energy, and environmental applications that demonstrate the efficacy of the approach and the utility of a well-designed multiphysics framework.

At the core of our framework is a black-box optimization algorithm which guides the process of evaluating candidate mechanisms. We apply the approach to several classes of two-player infinite games of incomplete information, producing optimal or nearly optimal mechanisms using various objective functions. By comparing our results with known optimal mechanisms, and in some cases improving on the best known mechanisms, we provide evidence that ours is a promising approach to parametrized mechanism design for infinite Bayesian games.

MS-based proteomic measurements have been used in a wide range of biological and biomedical investigations, including analysis of cellular responses and disease-specific post-translational modifications. These studies greatly enhance our understanding of the complex and dynamic nature of the proteome in biology and disease. Some MS techniques, such as those for targeted analysis, are being successfully applied for biomarker verification, whereas others, including global quantitative analysis (for example, for biomarker discovery), are more challenging and require further development. However, recent technological improvements in sample processing, instrumental platforms, data acquisition approaches and informatics capabilities continue to advance MS-based applications. Improving the detection of significant changes in proteins through these advances shows great promise for the discovery of improved biomarker candidates that can be verified pre-clinically using targeted measurements, and ultimately used in clinical studies - for example, for early disease diagnosis or as targets for drug development and therapeutic intervention. Here, we review the current state of MS-based proteomics with regard to its advantages and current limitations, and we highlight its translational applications in studies of protein biomarkers.

TI Seasonal variations in N2O emissions from central California SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article ID STILT MODEL AB We estimate nitrous oxide (N2O) emissions from Central California for the period of December 2007 through November 2009 by comparing N2O mixing ratios measured at a tall tower (Walnut Grove, WGC) with transport model predictions based on two global a priori N2O emission models (EDGAR32 and EDGAR42). Atmospheric particle trajectories and surface footprints are computed using the Weather Research and Forecasting (WRF) and Stochastic Time-Inverted Lagrangian Transport (STILT) models. Regression analyses show that the slopes of predicted on measured N2O from both emission models are low, suggesting that actual N2O emissions are significantly higher than the EDGAR inventories for all seasons. Bayesian inverse analyses of regional N2O emissions show that posterior annual N2O emissions are larger than both EDGAR inventories by factors of 2.0 +/- 0.4 (EDGAR32) and 2.1 +/- 0.4 (EDGAR42) with seasonal variation ranging from 1.6 +/- 0.3 to 2.5 +/- 0.4 for an influence region of Central California within approximately 150 km of the tower. These results suggest that if the spatial distribution of N2O emissions in California follows the EDGAR emission models, then actual emissions are 2.7 +/- 0.5 times greater than the current California emission inventory, and total N2O emissions account for 8.1 +/- 1.4% of total greenhouse gas emissions from California.

Our first-principles electronic structure analysis reveals its incompatibility with a simple Fermi-surface nesting or Mott insulator scenario, and suggests the picture of coexisting itinerant and localized electronic states. Consistently, we demonstrate that it can be unified with the metallic collinear or bicollinear antiferromagnetism of the vacancy-free parent compounds LaOFeAs, BaFe2As2, or FeTe in the spin-fermion model. These results indicate that the blocking effects of Hund's rule coupling and the resulting electron correlation are crucial to the electronic and magnetic structures of iron-based superconductors.

Our choice of parameters corresponds to a value of 160 MeV for the lightest pseudoscalar Goldstone mass and a physical value of the kaon mass. The three diagonal charge susceptibilities and the correlations among conserved charges have been extrapolated to the continuum limit in the temperature interval 150 MeV <= T <= 250 MeV. We compare our results with the hadron resonance gas (HRG) model calculations and find agreement with HRG model results only for temperatures T less than or similar to 150 MeV. We observe significant deviations in the temperature range 160 MeV less than or similar to T less than or similar to 170 MeV and qualitative differences in the behavior of the three conserved charge sectors. At T similar or equal to 160 MeV quadratic net baryon number fluctuations in QCD agree with HRG model calculations, while the net electric charge fluctuations in QCD are about 10% smaller and net strangeness fluctuations are about 20% larger. These findings are relevant to the discussion of freeze-out conditions in relativistic heavy ion collisions.

TI Translation-rotation decoupling and nonexponentiality in room temperature ionic liquids SO PHYSICAL REVIEW E LA English DT Article ID GLASS-FORMING LIQUIDS; SUPERCOOLED TRIS-NAPHTHYLBENZENE; PHYSICOCHEMICAL PROPERTIES; DIELECTRIC-RELAXATION; LIGHT-SCATTERING; SELF-DIFFUSION; SPIN-GLASSES; O-TERPHENYL; DYNAMICS; HETEROGENEITY AB Using a combination of light scattering techniques and broadband dielectric spectroscopy, we have measured the temperature dependence of structural relaxation time and self diffusion in three imidazolium-based room temperature ionic liquids: [bmim][NTf2], [bmim][PF6], and [bmim][TFA]. A detailed analysis of the results demonstrates that self diffusion decouples from structural relaxation in these systems as the temperature is decreased toward T-g. The degree to which the dynamics are decoupled, however, is shown to be surprisingly weak when compared to other supercooled liquids of similar fragility. In addition to the weak decoupling, we demonstrate that the temperature dependence of the structural relaxation time in all three liquids can be well described by a single Vogel-Fulcher-Tamann function over 13 decades in time from 10(-11) s up to 10(2) s. Furthermore, the stretching of the structural relaxation is shown to be temperature independent over the same range of time scales, i.e., time temperature superposition is valid for these ionic liquids from far above the melting point down to the glass transition temperature. We suggest that these phenomena are interconnected and all result from the same underlying mechanism-strong and directional intermolecular interactions.

TI Intestinal Tissues Induce an SNP Mutation in Pseudomonas aeruginosa That Enhances Its Virulence: Possible Role in Anastomotic Leak SO PLOS ONE LA English DT Article ID MULTIDRUG EFFLUX SYSTEM; RECTAL-CANCER; MEXT; REGULATOR; RESECTION; PAO1; DECONTAMINATION; PREVENTION; STRAINS; PLACEBO AB The most feared complication following intestinal resection is anastomotic leakage. In high risk areas (esophagus/rectum) where neoadjuvant chemoradiation is used, the incidence of anastomotic leaks remains unacceptably high (similar to 10%) even when performed by specialist surgeons in high volume centers. The aims of this study were to test the hypothesis that anastomotic leakage develops when pathogens colonizing anastomotic sites become in vivo transformed to express a tissue destroying phenotype. We developed a novel model of anastomotic leak in which rats were exposed to pre-operative radiation as in cancer surgery, underwent distal colon resection and then were intestinally inoculated with Pseudomonas aeruginosa, a common colonizer of the radiated intestine. Results demonstrated that intestinal tissues exposed to preoperative radiation developed a significant incidence of anastomotic leak (>60%; p<0.01) when colonized by P. aeruginosa compared to radiated tissues alone (0%). Phenotype analysis comparing the original inoculating strain (MPAO1-termed P1) and the strain retrieved from leaking anastomotic tissues (termed P2) demonstrated that P2 was altered in pyocyanin production and displayed enhanced collagenase activity, high swarming motility, and a destructive phenotype against cultured intestinal epithelial cells (i.e. apoptosis, barrier function, cytolysis). Comparative genotype analysis between P1 and P2 revealed a single nucleotide polymorphism (SNP) mutation in the mexT gene that led to a stop codon resulting in a non-functional truncated protein. Replacement of the mutated mexT gene in P2 with mexT from the original parental strain P1 led to reversion of P2 to the P1 phenotype. No spontaneous transformation was detected during 20 passages in TSB media. Use of a novel virulence suppressing compound PEG/Pi prevented P. aeruginosa transformation to the tissue destructive phenotype and prevented anastomotic leak in rats. This work demonstrates that in vivo transformation of microbial pathogens to a tissue destroying phenotype may have important implications in the pathogenesis of anastomotic leak.

Uniquely, the use of soft polymeric substrates enables the incorporation of advanced features beyond mechanical bendability and stretchability. In this paper, we describe several functionalities which can be achieved using engineered nanostructured materials. In particular, reversible binding, self-cleaning, antireflective and shape-reconfigurable properties are introduced for the realization of multifunctional, flexible electronic devices. Examples of flexible systems capable of spatial mapping and/or responding to external stimuli are also presented as a new class of user-interactive devices.

In this study, we examined whether serodiagnosis of Johne's disease (JD) can be conducted in a bead-based microfluidic assay system. Magnetic micro-beads were coated with antigens of the causative agent of JD, Mycobacterium avium subsp. paratuberculosis. The antigen-coated beads were incubated with serum samples of JD-positive or negative serum samples and then with a fluorescently-labeled secondary antibody (SAB). To confirm binding of serum antibodies to the antigen, the beads were subjected to flow cytometric analysis. Different conditions (dilutions of serum and SAB, types of SAB, and types of magnetic beads) were optimized for a large degree of differentiation between the JD-negative and JD-positive samples. Using the optimized conditions, we tested a well-classified set of 155 serum samples from JD-negative and JD-positive cattle by using the bead-based flow cytometric assay. Of 105 JD-positive samples, 63 samples (60%) showed higher antibody binding levels than a cut-off value determined by using antibody binding levels of JD-negative samples. In contrast, only 43-49 JD-positive samples showed higher antibody binding levels than the cut-off value when the samples were tested using commercially-available immunoassays. Microfluidic assays were performed by magnetically immobilizing a number of beads within a microchannel of a glass microchip and detecting antibody on the collected beads using laser-induced fluorescence. Antigen-coated magnetic beads treated with the bovine serum sample and fluorescently-labeled SAB were loaded into a microchannel to measure the fluorescence (reflecting level of antibody binding) on the beads in the microfluidic system. When the results of five bovine serum samples with the microfluidic system were compared to those analyzed with the flow cytometer, a high level of correlation (linear regression, r(2) = 0.994) was observed. In a further experiment, we magnetically immobilized antigen-coated beads in a microchannel, reacted the beads with serum and SAB in the channel, and detected antibody binding to the beads in the microfluidic system. A strong antibody binding in JD-positive serum was detected, whereas there was only negligible binding in negative control experiments. Our data suggest that the bead-based microfluidic system may form a basis for development of an on-site serodiagnosis of JD. (C) 2012 Elsevier B.V. All rights reserved.

TI Interception of Excited Vibrational Quantum States by O-2 in Atmospheric Association Reactions SO SCIENCE LA English DT Article ID PHASE BIMOLECULAR REACTIONS; REACTION DYNAMICS; MASTER EQUATION; CHEMICAL-DYNAMICS; CHLORINE ATOM; KINETICS; RADICALS; GASES; OH; CHEMISTRY AB Bimolecular reactions in Earth's atmosphere are generally assumed to proceed between reactants whose internal quantum states are fully thermally relaxed. Here, we highlight a dramatic role for vibrationally excited bimolecular reactants in the oxidation of acetylene. The reaction proceeds by preliminary adduct formation between the alkyne and OH radical, with subsequent O-2 addition. Using a detailed theoretical model, we show that the product-branching ratio is determined by the excited vibrational quantum-state distribution of the adduct at the moment it reacts with O-2. Experimentally, we found that under the simulated atmospheric conditions O-2 intercepts similar to 25% of the excited adducts before their vibrational quantum states have fully relaxed. Analogous interception of excited-state radicals by O-2 is likely common to a range of atmospheric reactions that proceed through peroxy complexes.

TI Biogenic Potassium Salt Particles as Seeds for Secondary Organic Aerosol in the Amazon SO SCIENCE LA English DT Article ID LIQUID PHASE-SEPARATION; ATMOSPHERE; FOREST; BASIN; RELEASE; NUCLEI; SULFUR; CLOUDS; CARBON; WET AB The fine particles serving as cloud condensation nuclei in pristine Amazonian rainforest air consist mostly of secondary organic aerosol. Their origin is enigmatic, however, because new particle formation in the atmosphere is not observed. Here, we show that the growth of organic aerosol particles can be initiated by potassium-salt-rich particles emitted by biota in the rainforest. These particles act as seeds for the condensation of low- or semi-volatile organic compounds from the atmospheric gas phase or multiphase oxidation of isoprene and terpenes. Our findings suggest that the primary emission of biogenic salt particles directly influences the number concentration of cloud condensation nuclei and affects the microphysics of cloud formation and precipitation over the rainforest.

TI Radiative Absorption Enhancements Due to the Mixing State of Atmospheric Black Carbon SO SCIENCE LA English DT Article ID CITY METROPOLITAN-AREA; LIGHT-ABSORPTION; CROSS-SECTION; AEROSOL; SOOT; MODELS; IMPACT; BROWN AB Atmospheric black carbon (BC) warms Earth's climate, and its reduction has been targeted for near-term climate change mitigation. Models that include forcing by BC assume internal mixing with non-BC aerosol components that enhance BC absorption, often by a factor of similar to 2; such model estimates have yet to be clearly validated through atmospheric observations. Here, direct in situ measurements of BC absorption enhancements (E-abs) and mixing state are reported for two California regions. The observed E-abs is small-6% on average at 532 nm-and increases weakly with photochemical aging. The E-abs is less than predicted from observationally constrained theoretical calculations, suggesting that many climate models may overestimate warming by BC. These ambient observations stand in contrast to laboratory measurements that show substantial E-abs for BC are possible.

The approach is more general and can be applied to other systems of partial differential equations. After discretization on unstructured meshes, a fully coupled multigrid preconditioned Newton-Krylov solution method is employed. The choice of aggregation scheme for generating coarser levels has a significant impact on the performance and scalability of the multigrid preconditioner. For the test cases considered, the uncoupled aggregation scheme, which aggregates/combines the immediate neighbors, followed by repartitioning and data redistribution for the coarser level matrices on a subset of the Message Passing Interface (MPI) processes, outperformed the two other approaches, including the baseline aggressive coarsening scheme. Scaling results are presented up to 147,456 cores on an IBM Blue Gene/P platform. A comparison of the scaling of a multigrid V-cycle and W-cycle is provided. Results for 65,536 cores demonstrate that a factor of 3.5 X reduction in time between the uncoupled aggregation and baseline aggressive coarsening scheme can be obtained by significantly reducing the iteration count due to the increased number of multigrid levels and the generation of better quality aggregates.

TI Epitaxial thin films of topological insulator Bi2Te3 with two-dimensional weak anti-localization effect grown by pulsed laser deposition SO THIN SOLID FILMS LA English DT Article DE Topological insulators; Pulsed laser deposition; Epitaxial thin films; Bismuth telluride; Weak anti-localization effect ID SURFACE-STATES; SB2TE3; NANORIBBONS; BI2SE3; LIMIT; SI AB We have grown high quality epitaxial topological insulator Bi2Te3 thin films on silicon (111) substrates by pulsed laser deposition. Systematic structural characterization of the films using X-ray diffraction and transmission electron microscopy has demonstrated that a low laser pulse rate is the key to achieving epitaxial films. The films show n-type metallic behavior, consistent with Te deficiency as determined by Rutherford backscattering spectrometry measurements. The A(1g) longitudinal optical phonon mode of Bi2Te3 was detected by time-resolved reflectivity measurements. A 2-dimensional (2-D) weak-antilocalization effect was also observed at low temperatures, which indicates the existence of topologically protected 2-D surface states in our thin films. This growth and characterization effort paves the way to fabricate multi-layer heterostructures of topological insulators along with ferromagnetic oxides and high temperature superconductors by the same growth technique in the search for physics arising from their interfacial couplings.

TI Spin crossover equation of state and sound velocities of (Mg0.65Fe0.35)O ferropericlase to 140 GPa SO JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH LA English DT Article ID EARTHS LOWER MANTLE; NUCLEAR RESONANT SCATTERING; POST-PEROVSKITE PHASE; MGSIO3 PEROVSKITE; HIGH-PRESSURE; IRON; TRANSITION; ELASTICITY; MAGNESIOWUSTITE; SUPERPLUMES AB We have determined the elastic and vibrational properties of periclase-structured (Mg0.65Fe0.35)O ("FP35"), a composition representative of deep mantle "pyrolite" or chondrite-pyroxenite models, from nuclear resonant inelastic x-ray scattering (NRIXS) and x-ray diffraction (XRD) measurements in diamond-anvil cells at 300 K. Combining with in situ XRD measurements, the Debye sound velocity of FP35 was determined from the low-energy region of the partial phonon density of states (DOS) obtained from NRIXS measurements in the pressure range of 70 to 140 GPa. In order to obtain an accurate description of the equation of state (EOS) for FP35, separate XRD measurements were performed up to 126 GPa at 300 K. A new spin crossover EOS was introduced and applied to the full P-V data set, resulting in a zero-pressure volume V-0 = 77.24 +/- 0.17 angstrom 3, bulk modulus K-0 = 159 +/- 8 GPa and its pressure-derivative K-0' = 4.12 +/- 0.42 for high-spin FP35 and K-0,K-LS = 72.9 +/- 1.3 angstrom(3), K-0,K-LS = 182 +/- 17 GPa with K-0,K-LS' fixed to 4 for low-spin FP35. The high-spin to low-spin transition occurs at 64 +/- 3 GPa. Using the spin crossover EOS and Debye sound velocity, we derived the shear (V-S) and compressional (V-P) velocities for FP35. Comparing our data with previous results on (Mg, Fe)O at similar pressures, we find that the addition of iron decreases both V-P and V-S, while elevating their ratio (V-P/V-S). Small amounts (<10%) of low-spin FP35 mixed with silicates could explain moderate reductions in wave speeds near the core mantle boundary (CMB), while a larger amount of FP35 near the CMB would not allow a large structure to maintain neutral buoyancy.

Magnetic field dependence of the nonlocal voltage induced by the flux flow shows that vortices form ordered vortex chains. Voltage asymmetry (rectification) with respect to the direction of vortex flow is evidence that vortex jamming strongly moderates vortex dynamics in mesoscopic geometries. The findings can be applied to superconducting devices exploiting vortex dynamics and vortex manipulation, including superconducting wires with engineered pinning centers.

We have employed nonresonant inelastic X-ray scattering (NIXS), which is a hard X-ray photon-in photon-out technique to monitor low energy core shell excitations and to obtain bulk sensitive information on the solid discharged products in Li-O-2 batteries using various electrolyte solvent/salt combinations. NIXS measurements were performed on cathodes after discharging the Li-O-2 cells using low discharge current (similar to 25 mA/g of carbon). NIXS results reveal that, even in cells containing current state-of-the-art electrolytes, the oxygen in the discharged products is bound predominantly to species other than a peroxide or lithia. This finding shows that electrolyte decomposition is a significant pathway during discharge of Li-O-2 batteries using ether and oligoether substituted silane based electrolytes.

TI Understanding Oxygen Reduction on Tantalum Oxyphosphate and Tantalum Oxide Supported Platinum by X-ray Absorption Spectroscopy SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID NEAR-EDGE STRUCTURE; FUEL-CELL; ADSORPTION SITES; METAL-CATALYSTS; IN-SITU; HYDROGEN; ELECTROCATALYSTS; PT(111); ELECTRODES; INTERFACE AB The Pt activity for the oxygen reduction reaction (ORR) is improved when Pt nanoparticles are supported on nanoscale layers of tantalum oxyphosphate (nominally, TaOPO4) on Vulcan carbon (VC) and heated at high temperature (660 C) in reducing conditions. We attempt to explain the increased activity of the Pt-TaOPO4/VC "HT" by comparison to other less-active electrocatalysts comprising Pt on tantalum oxide (Pt-Ta2O5/VC) and Pt-TaOPO4/VC heated to 200 degrees C in air. Our toolbox for this analysis contains the rotating disk electrode methodology for characterization of the ORR and high-angle annular dark-field scanning transmission electron microscopy with high-resolution energy-dispersive X-ray spectroscopy (EDS) capabilities. The adsorption of molecular species on the Pt and Ta is determined from the Delta mu XANES (X-ray absorption near-edge structure) adsorbate isolation technique of X-ray absorption spectroscopy (XAS) data for electrocatalsyts in situ, whereby H and OH adsorption products from water activation can be used to infer how an e lectrocatalyst would react for oxygen reduction. The Delta mu XANES analysis at the Pt L-2 edge suggests that interfacial hydrogen xists between the Pt and the support for Pt-Ta2O5/VC and Pt-TaOPO4/VC "HT" at potentials > 0.3 V vs RHE even after surface H is removed. More importantly, in the most active sample, Pt-TaOPO4/VC "HT", the onset potential for O(H) adsorption is highest in the Delta mu XANES. The XAS and microscopy/EDS results show that the Pt-TaOPO4/VC "HT" is Pt-Ta2O5/VC with polyphosphate groups directly associated with the Pt. From the body of results, we surmise that the nanoscale ILyer of polyphosphate on the Pt-TaOPO4/VC "HT" facilitates proton conduction to the Pt particles and hence moves the quilibrium for OH adsorption on the Pt to higher potentials.

The strong interaction of atomic oxygen with Au greatly affects the surface morphology by increasing the number of undercoordinated Au atoms and lifting the surface reconstruction. Through the combination of experimental and theoretical techniques, we have fully characterized an oxygen, modified Au(100) surface and determined the structure-reactivity relationship of O-Au species. Bulk-implanted oxygen does not affect the reactivity of Au surfaces and subsurface oxygen is found to be unstable. Oxygen stabilizes undercoordinated Au atoms on the surface and becomes highly active for oxidation reactions when adsorbed on unreconstructed Au(100) sites.

We exploit the low defect density of the high quality HOPG used here (similar to 10(9) defects cm(-2)) to eliminate the effects of step edges and defects on the graphite surface chemistry. Li causes C-Cl bond scission in CH3Cl, liberating CH3 radicals below 130 K. Ordinarily, two CH3 species would couple to form products such as C2H6, but in the presence of graphite, CH3 preferentially adsorbs on the flat basal plane of Li-treated graphite. A C-CH3 bond of 1.2 eV is formed, which is enhanced relative to CH3 binding to clean graphite (0.52 eV) due to donation of electrons from Li into the graphite and back-donation from graphite to CH3. A low yield of C-1, C-2, and C-3 hydrocarbon products above 330 K is found a long with a low yield of H-2. The low yield of these products indicates that the majority of the CH3 groups are irreversibly bound to the basal plane of graphite, and only a small fraction participate in the production of Cl-C-3 volatile products or in extensive dehydrogenation. Spin-polarized density functional theory calculations indicate that CH3 binds to the Li-treated surface with an activation energy of 0.3 eV to form a C-CH3 adsorbed surface species with sp(3) hybridization of the graphite, and the methyl carbon atoms is involved in bond formation. Bound CH3 radicals become mobile with 0.7 eV activation energy and can participate in combination reactions for the production of small yields of Cl-C-3 hydrocarbon products. We show that alkyl radical attachment to the graphite surface is kinetically preferred over hydrocarbon product desorption.

TI Electrophoretic Migration and Axial Diffusion of Individual Nanoparticles in Cylindrical Nanopores SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID SIZE-EXCLUSION CHROMATOGRAPHY; ANODIC ALUMINA; POROUS ALUMINA; CAPILLARY-ELECTROPHORESIS; SPHERICAL-PARTICLE; PROTEIN MOLECULES; MEMBRANES; SILICA; MOTION; ADSORPTION AB Membranes with straight, vertical nanopores have found widespread applications in chemical and biological sciences, including separation, detection, catalysis, and drug delivery. They can also serve as a model system to understand molecular behavior and fundamental mechanisms of separation, bridging the gap between conventional model systems such as flat surfaces and real chromatographic stationary phases such as micrometer-sized porous particles. We recently found that the axial motion of individual biomolecules inside nanopores can be significantly slower than in bulk solution. This suggests that either chromatographic adsorption was present and/or the viscosity inside the nanopores was unusually high. In this study, we measured the electrophoretic motion as well as the axial diffusion of individual nanoparticles in cylindrical alumina nanopores. We found that the electrophoretic mobilities and the diffusion coefficients of polystyrene nanoparticles were both substantially smaller compared to bulk solution independent of particle size or pore diameter. The results imply that the apparent solution viscosity in nanodomains is anomalous. C1 [Han, Rui; Wang, Gufeng; Qi, Shengda; Ma, Changbei; Yeung, Edward S.] US DOE, Ames Lab, Ames, IA 50011 USA.

Our data confirm the existence of three structural phase transitions previously identified with x-ray powder diffraction and reveal that the lower two transitions are associated with sequential collinear and canted ferrimagnetic transitions involving both cation sites. Through consideration of local crystal and spin symmetry, we further conclude that Fe2+ cations are ferro-orbitally ordered below 135 K and V3+ orbitals order at 60 K, in accordance with predictions for vanadium spinels with large trigonal distortions and strong spin-orbit coupling. Intriguingly, the direction of ordered vanadium spins at low temperature obey "ice rules" more commonly associated with the frustrated rare-earth pyrochlore systems. C1 [MacDougall, G. J.; Garlea, V.

Using an expansion of form factors into moments, we show that neutrinos from stopped pions can probe not only the second moment of the form factor (the neutron radius) but also the fourth moment. Using simple Monte Carlo techniques for argon, germanium, and xenon detectors of 3.5 tonnes, 1.5 tonnes, and 300 kg, respectively, we show that the neutron radii can be found with an uncertainty of a few percent when near a neutrino flux of 3 x 10(7) neutrinos/(cm(2) s). If the normalization of the neutrino flux is known independently, one can determine the moments accurately enough to discriminate among the predictions of various nuclear energy functionals.

CA Hadron Spectrum Collaboration TI S- and D-wave phase shifts in isospin-2 pi pi scattering from lattice QCD SO PHYSICAL REVIEW D LA English DT Article ID FINITE-VOLUME; GEV-C; SYSTEM AB The isospin-2 pi pi system provides a useful testing ground for determining elastic hadron scattering parameters from finite-volume spectra obtained using lattice QCD computations. A reliable determination of the excited state spectrum of two pions in a cubic box follows from variational analysis of correlator matrices constructed using a large basis of operators. A general operator construction is presented which respects the symmetries of a multihadron system in flight. This is applied to the case of pi pi and allows for the determination of the scattering phase shifts at a large number of kinematic points, in both S-wave and D-wave, within the elastic region. The technique is demonstrated with a calculation at a pion mass of 396 MeV, where the elastic scattering is found to be well described by a scattering length parametrization.

TI Holographic models and the QCD trace anomaly SO PHYSICAL REVIEW D LA English DT Article ID N FIELD-THEORIES; GAUGE-THEORIES; STRING THEORY; GRAVITY; PHYSICS AB Five-dimensional dilaton models are considered as possible holographic duals of the pure gauge QCD vacuum. In the framework of these models, the QCD trace anomaly equation is considered. Each quantity appearing in that equation is computed by holographic means. Two exact solutions for different dilaton potentials corresponding to perturbative and nonperturbative beta-functions are studied. It is shown that in the perturbative case, where the beta-function is the QCD one at leading order, the resulting space is not asymptotically anti-de Sitter. In the nonperturbative case, the model considered presents confinement of static quarks and leads to a nonvanishing gluon condensate, although it does not correspond to an asymptotically free theory. Calculating the Nambu-Goto action, corresponding to a small circular Wilson loop, leads to an expression for the gluon condensate. The validity of the trace anomaly equation is considered for both models. It holds for the perturbative model and it does not hold for the nonperturbative one. C1 [Goity, J.

TI Giant Ambipolar Rashba Effect in the Semiconductor BiTeI SO PHYSICAL REVIEW LETTERS LA English DT Article ID SPIN; PHASE AB We observe a giant spin-orbit splitting in the bulk and surface states of the noncentrosymmetric semiconductor BiTeI. We show that the Fermi level can be placed in the valence or in the conduction band by controlling the surface termination. In both cases, it intersects spin-polarized bands, in the corresponding surface depletion and accumulation layers. The momentum splitting of these bands is not affected by adsorbate-induced changes in the surface potential. These findings demonstrate that two properties crucial for enabling semiconductor-based spin electronics-a large, robust spin splitting and ambipolar conduction-are present in this material.

TI Complete Topology of Cells, Grains, and Bubbles in Three-Dimensional Microstructures SO PHYSICAL REVIEW LETTERS LA English DT Article ID GROWTH; ALGORITHM AB We introduce a general, efficient method to completely describe the topology of individual grains, bubbles, and cells in three-dimensional polycrystals, foams, and other multicellular microstructures. This approach is applied to a pair of three-dimensional microstructures that are often regarded as close analogues in the literature: one resulting from normal grain growth (mean curvature flow) and another resulting from a random Poisson-Voronoi tessellation of space. Grain growth strongly favors particular grain topologies, compared with the Poisson-Voronoi model. Moreover, the frequencies of highly symmetric grains are orders of magnitude higher in the grain growth microstructure than they are in the Poisson-Voronoi one. Grain topology statistics provide a strong, robust differentiator of different cellular microstructures and provide hints to the processes that drive different classes of microstructure evolution.

TI Knudsen Layer Reduction of Fusion Reactivity SO PHYSICAL REVIEW LETTERS LA English DT Article AB Knudsen layer losses of tail fuel ions can significantly reduce the fusion reactivity of multi-keV DT in capsules with small fuel rho r; sizable yield reduction can result for small inertial confinement fusion (ICF) capsules. This effect is most pronounced when the distance from a burning DT gas region to a nonreacting or cold wall is comparable to the mean free path of reacting fuel ions. A simplified asymptotic theory of Knudsen layer tail depletion is presented and a nonlocal reduced fusion reactivity model is obtained. Application of the model in simulations of ICF capsule implosion experiments gives calculated yields and ion temperatures that are in much closer agreement with observations than are the results of "nominal" or mixed simulations omitting the model.

TI Adsorbate Transport on Graphene by Electromigration SO PHYSICAL REVIEW LETTERS LA English DT Article ID FUNCTIONALIZATION AB Chemical functionalization of graphene holds promise for various applications ranging from nanoelectronics to catalysis, drug delivery, and nanoassembly. In many applications it is important to be able to transport adsorbates on graphene in real time. We propose to use electromigration to drive the adsorbate transport across the graphene sheet. To assess the efficiency of electromigration, we develop a tight-binding model of electromigration of an adsorbate on graphene and obtain simple analytical expressions for different contributions to the electromigration force. Using experimentally accessible parameters of realistic graphene-based devices as well as electronic structure theory calculations to parametrize the developed model, we argue that electromigration on graphene can be efficient. As an example, we show that the drift velocity of atomic oxygen covalently bound to graphene can reach similar to 1 cm/s. C1 [Solenov, Dmitry] USN, Res Lab, Washington, DC 20375 USA.

The beta-5 linkage comprises similar to 10% of the linkages in lignin. Density Functional Theory (DFT) was used to calculate the C-alpha-O and C-alpha-C-beta bond dissociation enthalpies (BDEs) for beta-5 models with varied substituents, which are important for understanding initial lignin decomposition. The C-alpha-O (C-alpha-C-beta) BDEs were in the range of 40-44 (57-62) kcal/mol. The products resulting from either homolysis are bi-radicals with multi-determinant character in the singlet electronic state. Multiconfiguration self-consistent field (MCSCF) theory results were used to verify that unrestricted DFT and broken-symmetry DFT were sufficient to study these reactions. (C) 2012 Elsevier B.V.

TI X-ray and optical wave mixing SO NATURE LA English DT Article ID PARAMETRIC CONVERSION; EXTREME-ULTRAVIOLET; DIFFRACTION; SCATTERING; DIAMOND; SOLIDS; FIELDS; BOND; PHOTONS; LASER AB Light-matter interactions are ubiquitous, and underpin a wide range of basic research fields and applied technologies. Although optical interactions have been intensively studied, their microscopic details are often poorly understood and have so far not been directly measurable. X-ray and optical wave mixing was proposed nearly half a century ago as an atomic-scale probe of optical interactions but has not yet been observed owing to a lack of sufficiently intense X-ray sources. Here we use an X-ray laser to demonstrate X-ray and optical sum-frequency generation. The underlying nonlinearity is a reciprocal-space probe of the optically induced charges and associated microscopic fields that arise in an illuminated material. To within the experimental errors, the measured efficiency is consistent with first-principles calculations of microscopic optical polarization in diamond. The ability to probe optical interactions on the atomic scale offers new opportunities in both basic and applied areas of science. C1 [Glover, T.

The volume fractions of transformed martensite and deformation twins at different stages of the deformation process were measured using X-ray diffraction method and TEM observations. It is found that the volume fraction of martensite monotonically increases with increasing strain but decreases with increasing strain rate. On the other hand, the volume fraction of twins increases with increasing strain for strain level less than 57%. Beyond that, the volume fraction of twins decreases with increasing strain. Careful TEM observations show that stacking faults (SFs) and twins preferentially occur before the nucleation of martensite. Meanwhile, both epsilon-martensite and alpha-martensite are observed in the deformation microstructures, indicating the co-existence of stress-induced-transformation and strain-induced-transformation. We also discussed the effects of twinning and martensite transformation on work-hardening as well as the relationship between stacking faults, twinning and martensite transformation.

TEM and electron tomographic measurements clearly demonstrated the uniform three-dimensional distribution of the ultrafine Pt NPs throughout the interior cavities of MIL-101. The resulting Pt@ MIL-101 composites represent the first highly active MOF-immobilized metal nanocatalysts for catalytic reactions in all three phases: liquid-phase ammonia borane hydrolysis, solid-phase ammonia borane thermal dehydrogenation, and gas-phase CO oxidation.

TI Furfuraldehyde Hydrogenation on Titanium Oxide-Supported Platinum Nanoparticles Studied by Sum Frequency Generation Vibrational Spectroscopy: Acid-Base Catalysis Explains the Molecular Origin of Strong Metal-Support Interactions SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID SINGLE-CRYSTAL SURFACES; CO2 HYDROGENATION; OXIDATION; CROTONALDEHYDE; SELECTIVITY; KINETICS; REMOVAL; PT(111); RHODIUM; AGENTS AB This work describes a molecular-level investigation of strong metal-support interactions (SMSI) in Pt/TiO2 catalysts using sum frequency generation (SFG) vibrational spectroscopy. This is the first time that SFG has been used to probe the highly selective oxide-metal interface during catalytic reaction, and the results demonstrate that charge transfer from TiO2 on a Pt/TiO2 catalyst controls the product distribution of furfuraldehyde hydrogenation by an acid-base mechanism. Pt nanoparticles supported on TiO2 and SiO2 are used as catalysts for furfuraldehyde hydrogenation. As synthesized, the Pt nanoparticles are encapsulated in a layer of poly(vinylpyrrolidone) (PVP). The presence of PVP prevents interaction of the Pt nanoparticles with their support, so identical turnover rates and reaction selectivity is observed regardless of the supporting oxide. However, removal of the PVP with UV light results in a 50-fold enhancement in the formation of furfuryl alcohol by Pt supported on TiO2, while no change is observed for the kinetics of Pt supported on SiO2. SFG vibrational spectroscopy reveals that a furfuryl-oxy intermediate forms on TiO2 as a result of a charge transfer interaction. This furfuryl-oxy intermediate is a highly active and selective precursor to furfuryl alcohol, and spectral analysis shows that the Pt/TiO2 interface is required primarily for H spillover. Density functional calculations predict that O-vacancies on the TiO2 surface activate the formation of the furfuryl-oxy intermediate via an electron transfer to furfuraldehyde, drawing a strong analogy between SMSI and acid-base catalysis.

CA ATLAS Collaboration TI Search for scalar top quark pair production in natural gauge mediated supersymmetry models with the ATLAS detector in pp collisions at root s=7 TeV SO PHYSICS LETTERS B LA English DT Article ID SUPERGAUGE TRANSFORMATIONS; CROSS-SECTION; BREAKING; EXTENSION; PARTICLE; CURRENTS; LEPTONS; PHYSICS; STATES; PIONS AB The results of a search for pair production of the lighter scalar partners of top quarks ((t) over bar (1)) in 2.05 fb(-1) of pp collisions at root s = 7 TeV using the ATLAS experiment at the LHC are reported. Scalar top quarks are searched for in events with two same flavour opposite-sign leptons (e, mu) with invariant mass consistent with the Z boson mass, large missing transverse momentum and jets in the final state. At least one of the jets is identified as originating from a b-quark. No excess over Standard Model expectations is found. The results are interpreted in the framework of R-parity conserving, gauge mediated Supersymmetry breaking 'natural' scenarios, where the neutralino ((chi) over bar (0)(1)) is the next-to-lightest supersymmetric particle. Scalar top quark masses up to 310 GeV are excluded for 115 GeV m(<(chi) over bar1)(0) 230 GeV at 95% confidence level, reaching an exclusion of m(<(t) over bar1) 330 GeV for m(<(chi) over bar1)(0) = 190 GeV. Scalar top quark masses below 240 GeV are excluded for all values of m((chi) over bar1)(0) > m(z). (c) 2012 CERN. Published by Elsevier B.V. All rights reserved.

CA CMS Collaboration TI Study of W boson production in PbPb and pp collisions at root s(NN)=2.76 TeV SO PHYSICS LETTERS B LA English DT Article DE CMS; Physics; Heavy-ions; W bosons ID HEAVY-ION COLLISIONS; PRODUCTION CROSS-SECTION; ATLAS DETECTOR; ROOT-S=7 TEV; LHC AB A measurement is presented of W-boson production in PbPb collisions carried out at a nucleon-nucleon (NN) centre-of-mass energy root S-NN of 2.76 TeV at the LHC using the CMS detector. In data corresponding to an integrated luminosity of 7.3 mu b(-1), the number of W -> mu v(mu) decays is extracted in the region of muon pseudorapidity vertical bar eta mu vertical bar < 2.1 and transverse momentum p(T)(mu) > 25 GeV/c. Yields of muons found per unit of pseudorapidity correspond to (159 +/- 10(stat.) +/- 12(syst.)) x 10(-8) W and (154 +/- 10(stat.) +/- 12(syst.)) x 10(-8) W- bosons per minimum-bias PbPb collision. The dependence of W production on the centrality of PbPb collisions is consistent with a scaling of the yield by the number of incoherent NN collisions. The yield of W bosons is also studied in a sample of pp interactions at root S = 2.76 TeV corresponding to an integrated luminosity of 231 nb(-1). The individual W+ and W- yields in PbPb and pp collisions are found to agree, once the neutron and proton content in Pb nuclei is taken into account. Likewise, the difference observed in the dependence of the positive and negative muon production on pseudorapidity is consistent with next-to-leading-order perturbative QCD calculations.

CA ZEUS Collaboration TI Measurement of isolated photons accompanied by jets in deep inelastic ep scattering SO PHYSICS LETTERS B LA English DT Article ID CENTRAL TRACKING DETECTOR; ZEUS BARREL CALORIMETER; E-T PHOTONS; CROSS-SECTION; P(P)OVER-BAR COLLISIONS; PROMPT PHOTONS; TRANSVERSE-MOMENTUM; HADRON-COLLISIONS; ROOT-S=1.8 TEV; MONTE-CARLO AB The production of isolated high-energy photons accompanied by jets has been measured in deep inelastic ep scattering with the ZEUS detector at HERA, using an integrated luminosity of 326 pb(-1). Measurements were made for exchanged photon virtualities Q(2), in the range 10 to 350 GeV2. The photons were measured in the transverse-energy and pseudorapidity ranges 4 < E-T(gamma) < 15 GeV and -0.7 < eta(gamma) < 0.9, and the jets were measured in the transverse-energy and pseudorapidity ranges 2.5 < E-T(jet) < 35 GeV and -15< eta(jet) < 1.8. Differential cross sections are presented as functions of these quantities. Perturbative QCD predictions give a reasonable description of the shape of the measured cross sections over most of the kinematic range but the absolute normalisation is typically in disagreement by 20-30%.

TI Search for the standard model Higgs boson produced in association with a Z boson in 7.9 fb(-1) of p(p)over-bar collisions at root s=1.96 TeV using the CDF ll detector SO PHYSICS LETTERS B LA English DT Article DE CDF; Higgs boson searches; Multivariate techniques ID ELECTROMAGNETIC CALORIMETER; UPGRADE; JET AB We present a search for the standard model Higgs boson produced in association with a Z boson, using up to 7.9 fb(-1) of integrated luminosity from p (p) over bar collisions collected with the CDF II detector. We utilize several novel techniques, including multivariate lepton selection, multivariate trigger parametrization, and a multi-stage signal discriminant consisting of specialized functions trained to distinguish individual backgrounds. By increasing acceptance and enhancing signal discrimination, these techniques have significantly improved the sensitivity of the analysis above what was expected from a larger dataset alone. We observe no significant evidence for a signal, and we set limits on the ZH production cross section. For a Higgs boson with mass 115 GeV/c(2), we expect (observe) a limit of 3.9 (4.8) times the standard model predicted value, at the 95% credibility level. (c) 2012 Elsevier B.V. All rights reserved.

Analysis of dehydrodiferulates (henceforth termed diferulates) in plant cell walls is useful in the evaluation: of the. quality of dairy; forages as animal feeds. Therefore, there has been considerable.. demand for quantities of diferulates as standards for such analyses. Described here are syntheses of diferulates from ethyl ferulate via biomimetic radical coupling reactions using the copper(II)-tetramethylethylenediamine [CuCl(OH) TMEDA] complex as oxidant or catalyst. Although CuCl(OH)-TMEDA oxidation of ethyl ferulate in acetonitrile produced mixtures composed of 8-O-4-, 8-5-, 8-8- (cyclic and noncyclic), and 5-5-coupled diferulates, a catalyzed oxidation using CuCl(OH)-TMEDA as catalyst and oxygen as an oxidant resulted in better overall yields of such diferulates. Flash chromatographic fractionation allowed isolation of 8-8-;,and diferulates. 8-5-Diferulate coeluted with 8-O-4-diferulate but was separated from it via crystallization; the 8-O-4 diferulate left in the Mother solution was isolated by rechromatography following a simple tetrabutylammonium. fluoride treatment:44,. converted 8-5-diferulate to another useful diferulate, 8-5-(noncyclic). diferulate. Therefore, six of the nine (5-5, 8-O-4, 8-5- c, 8-5-nc, 8-5-dc, 8-8-c, 8-8-nc, 8-8-THF, 4-O-5) diferulic acids that have to date been found in the alkaline hydrolysates of plant cell Walls can. be readily.

A simple and rapid (similar to 5 min) in-tube sample preparation was performed. Automated,flow injection introduced 1 mu L of the extracts directly into the mass spectrometer ion source without chromatographic separation. Sample-to-sample analysis time was 60 s. Quantitative capabilities of the flow-injection analysis were tested using the method of standard additions and SRM 3280. The quantity determined for each B vitamin in SRM 3280 was within the statistical range provided for the respective certified values. This approach was also applied to two different commercial vitamin supplement tablets and proved to be successful in the quantification of the selected B vitamins, as evidenced by an agreement with the label values and the results obtained using isotope dilution liquid chromatography/mass spectrometry.

For a one-component Bose gas, this approximation has the following properties: the Bose-Einstein condensation (BEC) phase transition is second order but the critical temperature T-c is not shifted from the noninteracting gas value T-0. The spectrum of excitations in the BEC phase resembles the Bogoliubov dispersion with the usual coupling constant replaced by the running coupling constant which depends on both temperature and momentum. We then study two-component Bose gases with both inter- and intraspecies interactions and focus on the stability of the mixture state above T-c. Our mean-field approximation predicts an instability from the mixture state to a phase-separated state when the ratio of the interspecies interaction strength to the intraspecies interaction strength (assuming equal strength for both species) exceeds a critical value. At high temperature this is a structural transition and the global translational symmetry is broken. Our work complements previous studies on the instability of the mixture phase in the presence of BEC.

The bromide tracer data were critical to improving the calibration of the flow model complicated by the highly dynamic nature of the flow field. However, most bromide concentrations were obtained from fully screened observation wells, lacking depth-specific resolution for vertical characterization. On the other hand, depth-specific temperature data were relatively simple and inexpensive to acquire. However, temperature-driven fluid density effects influenced heat plume movement. Moreover, the temperature data contained "noise" caused by heating during fluid injection and sampling events. Using the hydraulic conductivity distribution obtained from the calibration of the bromide transport model, the temperature depth profiles and arrival times of temperature peaks simulated by the heat transport model were in reasonable agreement with observations. This suggested that heat can be used as a cost-effective proxy for solute tracers for calibration of the hydraulic conductivity distribution, especially in the vertical direction. However, a heat tracer test must be carefully designed and executed to minimize fluid density effects and sources of noise in temperature data. A sensitivity analysis also revealed that heat transport was most sensitive to hydraulic conductivity and porosity, less sensitive to thermal distribution factor, and least sensitive to thermal dispersion and heat conduction. This indicated that the hydraulic conductivity remains the primary calibration parameter for heat transport.

The recovered cell wall biopolymers were characterized based on total extraction, precipitation using ethanol or acidification, xylan content, and molar mass of the recovered precipitates. The extractability of cell wall polymers was clearly shown to be a function of the biomass type with more than 50% of the cell walls of switchgrass solubilized by alkali while only up to 20% of the maple was solubilized under comparable conditions. Precipitation with ethanol resulted in high recovery yields of hemicelluloses from the original biomass for silver birch and switchgrass, and most notably, the birch precipitates contained double the hemicellulose content of the precipitates from other feedstock alkali extracts (80% versus 30-50%). The molar masses of the recovered hemicellulosic polysaccharides were characterized using size exclusion chromatography (SEC) and an assay to quantify polysaccharide reducing ends. SEC analysis showed that the biopolymers exhibited a strong tendency to self-associate during elution and that this aggregation could be eliminated through sonication. The reducing end method showed an increase in the number-average degree of polymerization toward an asymptotic maximum with increasing extraction pH, and this value was significantly increased by bleaching the precipitate to remove interference by nonpolysaccharides.

We investigate, within a tight-binding description, the effects of disorder in the on-site (diagonal disorder) term in the Hamiltonian as well as in the hopping integral (off-diagonal disorder) on the electronic dispersion and density of states by the augmented space recursion method. Extrinsic off-diagonal disorder is shown to have dramatic effects on the two-dimensional (2D) Dirac cone, including asymmetries in the band structures as well as the presence of discontinuous bands (because of resonances) in certain limits. Disorder-induced broadening, related to the scattering length (or lifetime) of Bloch electrons, is modified significantly with increasing strength of disorder. We propose that our methodology is suitable for the study of the effects of disorder in other 2D materials, such as a boron nitride monolayer.

We show that the inevitable presence of the metallic 1D CuO chain layer lying between the CuO2 bilayers in YBCO renders an electron-like Fermi surface in the doping range as wide as p = 0.05 to overdoping. With underdoping, a pseudogap opening in the CuO2 state reduces its hole-carrier contribution, and, therefore, the net electron-like quasiparticles dominate the transport properties, and a negative Hall resistance commences. We also show that the observation of in-plane anisotropy in the Nernst signal-which was taken as a definite evidence of the electronic "nematic" pseudogap phase-is naturally explained by including the "quasiuniaxial" metallic chain state. Finally, we comment on how the chain state can also lead to electron-like quantum oscillations. C1 Los Alamos Natl Lab, Div Theoret, Los Alamos, NM 87545 USA.

This model allows us to calculate the scattering matrix elements of the interface for a plane wave of light normally incident upon the interface from either direction. The resulting scattering matrix provides insight into the non-Maxwellian boundary conditions present at the interface between a homogeneous medium and a metamaterial/photonic crystal with strong spatial dispersion. We present the model mathematically. As an example, the model is used to calculate the scattering matrix of the interface between vacuum and a simple photonic crystal. Several tests of the calculated scattering matrix elements are presented. Finally, we used the results of the scattering model to postulate possible forms for the non-Maxwellian boundary conditions.

Total energies and relaxed atomic geometries are calculated within density functional theory using the local density approximation (LDA). We conclude from these results that the (110) and (100) surfaces are most stable. Their termination depends on the experimental situation: While under oxygen-rich preparation conditions the oxygen termination is preferred, reduced surfaces are more likely to occur in the oxygen-poor limit. In addition, electronic band structures and densities of states are calculated using a recently developed approximate quasiparticle approach, the LDA-1/2 method. Except for the SnO-terminated (110) surface, all other faces are found to be insulating and O- or Sn-derived surface states appear in the projected bulk fundamental gap. While the surface barrier heights vary by more than 2 eV with orientation and termination, the ionization energies tend to the smallest values for the energetically favored surfaces.

TI Systematic study of p-shell nuclei via single-nucleon knockout reactions SO PHYSICAL REVIEW C LA English DT Article ID MONTE-CARLO CALCULATIONS; EXOTIC NUCLEI AB A systematic investigation of the inclusive cross sections for single-nucleon knockout reactions from p-shell nuclei has been performed. A total of seven reactions were studied for projectiles with masses between A = 7 and 10, having a wide range of nucleon separation energies. Results were obtained for a range of incident beam energies and targets. These differences were found to have a minimal impact on the deduced cross sections. Experimental results were compared to theoretical predictions based on variational Monte Carlo (VMC) nuclear structure calculations, whose radial overlap functions and neutron and proton densities were included in the reaction description. These results are compared with the conventional model, developed for heavier nuclei, that uses shell-model and Hartree-Fock structure inputs. The VMC-based calculations agreed with the experimental data for several reactions where deeply bound nucleons are removed but does not describe some of the more weakly bound nucleon removal cases with comparable accuracy.

TI Comparative Metagenomics of Toxic Freshwater Cyanobacteria Bloom Communities on Two Continents SO PLOS ONE LA English DT Article ID 16S RIBOSOMAL-RNA; MICROCYSTIS-AERUGINOSA; LAKE TAIHU; MICROBIAL COMMUNITY; ENZYME-ACTIVITIES; CHINA; PHOSPHORUS; GROWTH; NITROGEN; BACTERIA AB Toxic cyanobacterial blooms have persisted in freshwater systems around the world for centuries and appear to be globally increasing in frequency and severity. Toxins produced by bloom-associated cyanobacteria can have drastic impacts on the ecosystem and surrounding communities, and bloom biomass can disrupt aquatic food webs and act as a driver for hypoxia. Little is currently known regarding the genomic content of the Microcystis strains that form blooms or the companion heterotrophic community associated with bloom events. To address these issues, we examined the bloom-associated microbial communities in single samples from Lake Erie (North America), Lake Tai (Taihu, China), and Grand Lakes St. Marys (OH, USA) using comparative metagenomics. Together the Cyanobacteria and Proteobacteria comprised >90% of each bloom bacterial community sample, although the dominant phylum varied between systems. Relative to the existing Microcystis aeruginosa NIES 843 genome, sequences from Lake Erie and Taihu revealed a number of metagenomic islands that were absent in the environmental samples. Moreover, despite variation in the phylogenetic assignments of bloom-associated organisms, the functional potential of bloom members remained relatively constant between systems. This pattern was particularly noticeable in the genomic contribution of nitrogen assimilation genes. In Taihu, the genetic elements associated with the assimilation and metabolism of nitrogen were predominantly associated with Proteobacteria, while these functions in the North American lakes were primarily contributed to by the Cyanobacteria. Our observations build on an emerging body of metagenomic surveys describing the functional potential of microbial communities as more highly conserved than that of their phylogenetic makeup within natural systems.

Silica and silicates are widely used in medicine and industry as well as in micro- and nano-optics and electronics. However, the fabrication of glass fibres and components requires high temperature and non-physiological conditions, in contrast to biosilica structures in animals and plants. Here, we show for the first time the use of recombinant silicatein-alpha, the most abundant subunit of sponge proteins catalyzing biosilicification reactions, to direct the formation of optical waveguides in-vitro through soft microlithography. The artificial biosilica fibres mimic the natural sponge spicules, exhibiting refractive index values suitable for confinement of light within waveguides, with optical losses in the range of 5-10 cm(-1), suitable for application in lab-on-chips systems. This method extends biosilicification to the controlled fabrication of optical components by physiological processing conditions, hardly addressed by conventional technologies.

TI The compressibility of high purity YbB2 SO JOURNAL OF PHYSICS-CONDENSED MATTER LA English DT Article ID ELASTIC-CONSTANTS; DIBORIDE; PRESSURE; DIAMOND AB The compressibility and phase stability of YbB2 are investigated under high pressure using high-resolution synchrotron x-ray diffraction in a diamond anvil cell. The bulk modules of high purity YbB2 is obtained as similar to 182 GPa using the Birch-Murnaghan equation of state. The patterns measured up to 20 GPa and the pressure dependence of normalized lattice parameters, a/a(0) and c/c(0), reveal that the compressibility of YbB2 is low and fairly isotropic, and this material can be classified as a hard material. X-ray photoemission studies demonstrate that Yb in YbB2 has a mostly trivalent valence state at room temperature. Moreover, sample preparation details provide a new insight into the high purity synthesis of YbB2 at ambient pressure and moderate temperatures. The presented structural and compressibility results are in agreement with the available theoretical and experimental data on binary rare-earth borides and can serve as a reliable reference for future studies.

TI Variational approach for nonpolar solvation analysis SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID POISSON-BOLTZMANN EQUATION; DENSITY-FUNCTIONAL THEORY; HYDRATION FREE-ENERGIES; ELECTROSTATIC ENERGIES; MOLECULAR-SURFACES; REACTION FIELD; MODEL; FORCES; SIMULATIONS; INTERFACE AB Solvation analysis is one of the most important tasks in chemical and biological modeling. Implicit solvent models are some of the most popular approaches. However, commonly used implicit solvent models rely on unphysical definitions of solvent-solute boundaries. Based on differential geometry, the present work defines the solvent-solute boundary via the variation of the nonpolar solvation free energy. The solvation free energy functional of the system is constructed based on a continuum description of the solvent and the discrete description of the solute, which are dynamically coupled by the solvent-solute boundaries via van der Waals interactions. The first variation of the energy functional gives rise to the governing Laplace-Beltrami equation. The present model predictions of the nonpolar solvation energies are in an excellent agreement with experimental data, which supports the validity of the proposed nonpolar solvation model.

TI Changes in the intermediate water mass formation rates in the global ocean for the Last Glacial Maximum, mid-Holocene and pre-industrial climates SO PALEOCEANOGRAPHY LA English DT Article ID SUB-ANTARCTIC MODE; PMIP2 COUPLED SIMULATIONS; NORTH-ATLANTIC OCEAN; PAST 25,000 YEARS; SOUTHERN-OCEAN; ATMOSPHERIC CO2; THERMOHALINE CIRCULATION; ANTHROPOGENIC CO2; THERMOCLINE WATERS; INDIAN OCEANS AB The paleoclimate version of the National Center for Atmospheric Research Community Climate System Model version 3 (NCAR-CCSM3) is used to analyze changes in the water formation rates in the Atlantic, Pacific, and Indian Oceans for the Last Glacial Maximum (LGM), mid-Holocene (MH) and pre-industrial (PI) control climate. During the MH, CCSM3 exhibits a north-south asymmetric response of intermediate water subduction changes in the Atlantic Ocean, with a reduction of 2 Sv in the North Atlantic and an increase of 2 Sv in the South Atlantic relative to PI. During the LGM, there is increased formation of intermediate water and a more stagnant deep ocean in the North Pacific. The production of North Atlantic Deep Water (NADW) is significantly weakened. The NADW is replaced in large extent by enhanced Antarctic Intermediate Water (AAIW), Glacial North Atlantic Intermediate Water (GNAIW), and also by an intensified of Antarctic Bottom Water (AABW), with the latter being a response to the enhanced salinity and ice formation around Antarctica. Most of the LGM intermediate/mode water is formed at 27.4 < sigma(theta) < 29.0 kg/m(3), while for the MH and PI most of the subduction transport occurs at 26.5 < sigma(theta) < 27.4 kg/m(3). The simulated LGM Southern Hemisphere winds are more intense by 0.2-0.4 dyne/cm(2). Consequently, increased Ekman transport drives the production of intermediate water (low salinity) at a larger rate and at higher densities when compared to the other climatic periods.

TI Targeted deletion of Sost distal enhancer increases bone formation and bone mass SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE osteocytes ID VAN-BUCHEM-DISEASE; RECEPTOR ACTIVATOR; ESCHERICHIA-COLI; CRE RECOMBINASE; TRANSGENIC MICE; LRP5 GENE; EXPRESSION; SCLEROSTIN; DENSITY; MEF2C AB The Wnt antagonist Sost has emerged as a key regulator of bone homeostasis through the modulation of Lrp4/5/6 Wnt coreceptors. In humans, lack of Sclerostin causes sclerosteosis and van Buchem (VB) disease, two generalized skeletal hyperostosis disorders that result from hyperactive Wnt signaling. Unlike sclerosteosis, VB patients lack SOST coding mutations but carry a homozygous 52 kb noncoding deletion that is essential for the transcriptional activation of SOST in bone. We recently identified a putative bone enhancer, ECR5, in the VB deletion region, and showed that the transcriptional activity of ECR5 is controlled by Mef2C transcription factor in vitro. Here we report that mice lacking ECR5 or Mef2C through Col1-Cre osteoblast/osteocyte-specific ablation result in high bone mass (HBM) due to elevated bone formation rates. We conclude that the absence of the Sost-specific long-range regulatory element ECR5 causes VB disease in rodents, and that Mef2C is the main transcription factor responsible for ECR5-dependent Sost transcriptional activation in the adult skeleton.

TI 4-O-methylation of glucuronic acid in Arabidopsis glucuronoxylan is catalyzed by a domain of unknown function family 579 protein SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE recalcitrance; biosynthesis ID CARBOHYDRATE-BINDING MODULES; SECONDARY CELL-WALL; PLANT O-METHYLTRANSFERASES; ADENOSYL-L-METHIONINE; LIGNOCELLULOSIC BIOMASS; MUTANTS REVEALS; XYLAN SYNTHESIS; BIOSYNTHESIS; HEMICELLULOSE; RECALCITRANCE AB The hemicellulose 4-O-methyl glucuronoxylan is one of the principle components present in the secondary cell walls of eudicotyledonous plants. However, the biochemical mechanisms leading to the formation of this polysaccharide and the effects of modulating its structure on the physical properties of the cell wall are poorly understood. We have identified and functionally characterized an Arabidopsis glucuronoxylan methyltransferase (GXMT) that catalyzes 4-O-methylation of the glucuronic acid substituents of this polysaccharide. AtGXMT1, which was previously classified as a domain of unknown function (DUF) 579 protein, specifically transfers the methyl group from S-adenosyl-L-methionine to O-4 of a-D-glucopyranosyluronic acid residues that are linked to O-2 of the xylan backbone. Biochemical characterization of the recombinant enzyme indicates that GXMT1 is localized in the Golgi apparatus and requires Co2+ for optimal activity in vitro. Plants lacking GXMT1 synthesize glucuronoxylan in which the degree of 4-O-methylation is reduced by 75%. This result is correlated to a change in lignin monomer composition and an increase in glucuronoxylan release during hydrothermal treatment of secondary cell walls. We propose that the DUF579 proteins constitute a previously undescribed family of cation-dependent, polysaccharide-specific O-methyl-transferases. This knowledge provides new opportunities to selectively manipulate polysaccharide O-methylation and extends the portfolio of structural targets that can be modified either alone or in combination to modulate biopolymer interactions in the plant cell wall.

Yu, Luping TI Mediating Solar Cell Performance by Controlling the Internal Dipole Change in Organic Photovoltaic Polymers SO MACROMOLECULES LA English DT Article ID SEMICONDUCTING POLYMERS; CONVERSION EFFICIENCY; MORPHOLOGY; DESIGN AB We report synthesis and characterizations of two novel series of polymers, namely the PBTZ and PBIT series. The PBTZ1 polymer was synthesized as a copolymer of 4,8-bis(2-butyloctyl)benzo[1,2-b:4,5-b']dithiophene (BDT) along with 2,5-bis(2-ethylhexyl)-3,6-bisthiazol-2-yl-2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione (TzDPP), while PBTZ2 was a copolymer of TzDPP and 2-(1-butylheptyl)-thieno[3,4-d]thiazole (TTz). The PBIT series based on dithienopyrrolobenzothiadiazole (DPBT), and BDT was also synthesized. The PBIT series of polymers showed enhanced ground and excited state dipole moments (mu(g) and mu(e)) when compared to the previously reported PBB3 polymer, while PBTZ1 showed the largest dipole change (1.52 D) from ground to excited state (Delta mu(ge)) in respective single polymer units. It was found that the power conversion efficiencies of the polymer series were strongly correlated to Delta mu(ge). The results reported demonstrate the utility of the calculated parameter Delta mu(ge) of single units of the polymers to predict the performance of donor-acceptor copolymers in photovoltaic devices. We rationalize this result based on the large degree of polarization in the excited state, which effectively lowers the Coulomb binding energy of the exciton in the excited state and leads to faster charge separation kinetics, thus facilitating the full separation of electron and hole.

The fiillerene-attached copolymers had good solubility (>30 g L-1 chlorobenzene) with high molecular weights (M-n > 20 000). The diblock copolymer films formed clear nanostructures with sizes of ca. 20 nm, driven by crystallization of the poly(3-hexylthiophene) block and aggregation of the fullerene groups, as observed in AFM phase images. The copolymer-based photovoltaic device showed a power conversion efficiency of 2.5%, with a much higher fill factor of 0.63 in comparison to the previously reported single component devices. These results indicate that rational material designs enable the construction of suitable donor-acceptor nanostructures for photovoltaic applications, without relying on the mixing of materials.

Reaction of the PGMA block with surface hydroxyl groups not only anchors the copolymer to the surface, but limits chain mobility, creating brush-like structures comprising PVDMA blocks, which contain reactive azlactone groups. The block copolymers are spin coated at various solution concentrations and annealed at elevated temperature to optimize film deposition to achieve a molecularly uniform layer. The thickness and structure of the polymer thin films are investigated by ellipsometry, infrared spectroscopy, and neutron reflectometry. The results show that deposition of PGMA-b-PVDMA provides a useful route to control film thickness while preserving azlactone groups that can be further modified with biotin-poly(ethylene glycol)amine to generate designer surfaces. The method described herein offers guidance for creating highly functional surfaces, films, or coatings through the use of dually reactive block copolymers and postpolymerization modification.

Herein, we demonstrate that 2-ureido-4[1H]-pyrimidinone (UPy) quadruple hydrogen bonding interactions can be used to prevent micrometer-scale phase separation at temperatures and processing conditions typically used to prepare bulk heterojunction OPVs. UPy-terminated polymers are synthesized by coupling hydroxyl or primary amine terminated polymers to a reactive isocyanate-UPy group in a one-step reaction. Polymer blend films are subsequently prepared by solution blending, casting onto a surface, and thermal and/or solvent annealing. Film microstructure including the presence of phase-separated domains and polymer crystallinity is analyzed by optical microscopy, atomic force microscopy (AFM), and grazing-incidence wide-angle X-ray scattering (GIWAXS). In contrast to unmodified polymer blends, blends of UPy-terminated polymers do not exhibit micrometer-scale phase separation after extended thermal annealing. AFM reveals the presence of crystalline nanofibers and, in some cases, 100-300 nm phase-separated domains in UPy-mediated polymer blends. Fluorescence measurements indicate that UPy modification increases fluorescence quenching in solutions of donor and acceptor polymers, due to hydrogen-bonding associations which reduce the average distance for energy and/or electron transfer. These results show that UPy-mediated interactions can suppress micrometer-scale phase separation in bulk heterojunction polymer blends at temperatures and processing conditions typically used to prepare bulk-heterojunction OPVs. As a result, UPy functionalization may be a powerful route for improving the performance of all-polymer OPVs.

When the temperature is increased, the polymer transitions from an extended coil conformation to a collapsed structure. We performed molecular dynamics simulations of aqueous solutions of single chain, syndiotactic PNIPAM oligomers over a wide range of temperatures and varying degrees of polymerization to elucidate the effect of oligomer length on the single chain transition temperature, T-1. We have reproduced recent measurements of the transition temperature increasing with decreasing oligomer chain length. Examination of the chain structure reveals that conformations above T-1 bend to bring hydrophobic segments together to shield them from the water. The constraints of the dihedral dynamics require elevated temperatures for shorter chains to bend sharply enough in order to undergo the transition. This result is confirmed by calculations of the solvent accessible surface area, which shows an increase in shielding of the hydrophobic groups with increasing oligomer length above T-1.

While many materials have been synthesized by ALD, the technologically important metal sulfides are underexplored, and homogeneous quaternary metal sulfides are absent from the literature. We report an ALD process to synthesize Cu2ZnSnS4 (CZTS), a potentially low cost semiconductor being explored for photovoltaic applications.. Two strategies are reported: one in which a trilayer stack of binary metal sulfides (i.e., Cu2S, SnS2 and ZnS) is deposited and mixed by thermal annealing, as well as a supercycle strategy that is similar to the conventional ALD procedure for forming nanolaminates. Both routes rely on the facile solid state diffusion of chalcogenides for mixing. For this ALD route to the CZTS system; the challenges are nucleation, ion exchange between the film and the volatile chemical precursors, and phase stability of binary SnS2. The thin films were made with no sulfurization step. The X-ray diffraction and Raman spectra were consistent with the formation of CZTS. X-ray fluorescence measurements revealed that the films contained the expected amount of sulfur based on the target oxidation states. Photoelectrochemical measurements under simulated AM1.5 illumination using Eu3+ as an electron acceptor demonstrated that the films were photoactive and had an average internal quantum efficiency (IQE) of 12%.

TI Novel Synthesis of Chalcopyrite CuxInyS2 Quantum Dots with Tunable Localized Surface Plasmon Resonances SO CHEMISTRY OF MATERIALS LA English DT Article DE quantum dots; surface plasmon; photovoltaics; low toxicity; CuInS2 ID NANOCRYSTALS; PHOTOVOLTAICS AB The burgeoning field of thin film quantum dot photovoltaics has made considerable strides toward efficient and inexpensive forms of third generation solar cells. However, these technologies have largely been based upon toxic metal-containing materials, limiting their foreseeable applications. Here we present a synthesis of nontoxic and stable CuxInyS2 quantum dots with tunable size and band gap. Interestingly, this synthesis leads to the presence of a broad band and size dependent absorption peak in the infrared (IR), attributed to localized surface plasmon resonances (LSPRs). Due to the sensitivity of their LSPR peak to quantum dot size and solvent refractive index, these quantum dots provide an attractive candidate for tunable plasmon resonance applications. And, if these LSPRs are found to be coupled with excitonic transitions, they may result in sizable increases in photovoltaic efficiency.

Here, we photocross-linked two poly(epsilon-caprolactone) triacrylates (PCLTAs) with number-average molecular weights of similar to 7000 and similar to 10000 g mol(-1) into substrates with parallel microgrooves. Cross-linked PCLTA7k was amorphous and soft, while cross-linked PCLTA10k was semicrystalline with a stiffer surface. We employed different dimensions of interests for the parallel microgrooves, that is, groove widths of 5, 15, 45, and 90 mu m and groove depths of 0.4, 1, 5, and 12 mu m. The behaviors of rat Schwann cell precursor line (SpL201) cells with the glial nature and pheochromocytoma (PC12) cells with the neuronal nature were studied on these microgrooved substrates, showing distinct preference to the substrates with different mechanical properties. We found different threshold sensitivities of the two nerve cell types to topographical features when their cytoskeleton and nuclei were altered by varying the groove depth and width. Almost all of the cells were aligned in the narrowest and deepest microgrooves or around the edge of microgrooves. Oriented SpL201 cell movement had a higher motility as compared to unaligned ones. After forskolin treatment, SpL201 cells demonstrated significantly upregulated S-100 and O4 on stiffer substrates or narrower microgrooves, suggesting more differentiation toward early Schwann cells (SCs). PC12 neurites were oriented with enhanced extension in narrower microgrooves. The present results not only improve our fundamental understanding on nerve cellsubstrate interactions, but also offer useful conduit materials and appropriate feature dimensions to foster guidance for axonal growth in peripheral nerve regeneration.

Large areas display a squarelike (root 2 x root 2) R45 degrees structure with surface-pinned antiphase domains. The domain walls exhibit C-2 symmetry, in contrast with the bulk C-2v geometric structure.

These results invalidate the conclusion of phase-transition-induced elastic softening recently reported based on nonmagnetic simulations for cubic CrN [Nature Mater. 8, 947 (2009)]. On the other hand, they provide the only experimental evidence to support the computational models involving the local magnetic moment of Cr atoms [Nature Mater. 9, 283 (2010)], indicating that atomic spin has a profound influence on the material's elastic properties.

CA BABAR Collaboration TI Precise measurement of the e(+)e(-) -> pi(+)pi(-)(gamma) cross section with the initial-state radiation method at BABAR SO PHYSICAL REVIEW D LA English DT Article ID PION FORM-FACTOR; TO-LEADING ORDER; MAGNETIC-MOMENT; CMD-2 DETECTOR; ENERGY-RANGE; SPECTRAL FUNCTIONS; TAGGED PHOTONS; KLOE DETECTOR; MONTE-CARLO; B-FACTORIES AB A precise measurement of the cross section of the process e(+)e(-) -> pi(+)pi(-) (gamma) from threshold to an energy of 3 GeV is obtained with the initial-state radiation (ISR) method using 232 fb(-1) of data collected with the BABAR detector at e(+)e(-) center-of-mass energies near 10.6 GeV. The ISR luminosity is determined from a study of the leptonic process e(+)e(-) -> mu(+)mu(-) (gamma)gamma(ISR), which is found to agree with the next-to-leading-order QED prediction to within 1.1%. The cross section for the process e(+)e(-) -> pi(+)pi(-) (gamma) is obtained with a systematic uncertainty of 0.5% in the dominant rho resonance region. The leading-order hadronic contribution to the muon magnetic anomaly calculated using the measured pi pi cross section from threshold to 1.8 GeV is (514.1 +/- 2.2(stat) +/- 3.1(sys)) x 10(-10).

TI Thermally-Activated Pentanol Delivery from Precursor Poly(p-phenylenevinylene)s for MEMS Lubrication SO MACROMOLECULAR RAPID COMMUNICATIONS LA English DT Article DE conjugated polymers; MEMS; vapor-phase lubrication ID VAPOR-PHASE LUBRICATION; POLYMERS; MOS2; POLYMERIZATION; CHEMISTRY; SURFACES; BEHAVIOR; WEAR; PPV AB The synthesis of two new polyphenylene vinylene (PPV) precursor polymers which can be thermally induced to eliminate pentanol is presented. Pentanol has recently been discovered to be a very useful lubricant in MicroElectroMechanical Systems. The utilization of the elimination reaction of precursor polymers to PPV as a small molecule delivery platform has, to the best of our knowledge, not been previously reported. The elimination reactions were examined using thermal gravimetric analysis, gas chromatography, and UVVis spectroscopy. Using PPV precursors allows for (1) a high loading of lubricant (one molecule per monomeric unit), (2) a platform that requires relatively high temperatures (>145 degrees C) to eliminate the lubricant, and (3) a non-volatile, mechanically and chemically stable by-product of the elimination reaction (PPV).

Two methods for initiation of laser-induced breakdown are used, intrinsic, involving relatively large energy deposition brought about by focusing of the laser beam to high intensities, and extrinsic, arising from more localized deposition due to the presence of pre-existing absorbing damage initiating defects. Each method leads to a very different volume of material being affected, which provides for different material thermal relaxation times to help better understand the processes involved.

Measurements at 77K yield minority carrier lifetimes of 3 mu s and 9 mu s for the InAsSb alloy and InAs/InAsSb superlattice, respectively. The un-optimized InAsSb-based materials also exhibit long lifetimes (>850 ns) at temperatures up to 250 K, indicating the potential use for these materials as mid-wave infrared photodetectors with improved performance over current type-II superlattice photodetectors at both cryogenic and near-ambient operating temperatures.

In both cases, surfactant incorporation enabled layer-by-layer growth and a smooth terminal surface by stabilizing the {111} rocksalt facet. Metal-insulator-semiconductor capacitor structures were fabricated on n-type GaN. A comparison of leakage current density for conventional and surfactant-assisted growth reveals a nearly 100x reduction in leakage current density for the surfactant-assisted samples. These data verify numerous predictions regarding the role of H-termination in regulating the habit of rocksalt crystals. (C) 2012 American Institute of Physics.

HfB2 conductive coatings grown at low temperatures using chemical vapor deposition possess high mechanical properties that are ideal for this technology. Here, we show that HfB2 coated probe-tips can potentially enhance a previously demonstrated 5 km wear endurance mechanism developed using PtIr coated probe-tips to beyond 8 km, thereby increasing the lifetime of probe-based memory devices. We foresee the extension of this coating technology to other scanning probe based systems and nanoelectromechanical devices. (C) 2012 American Institute of Physics.

We demonstrate this technique in obtaining absorption spectrum of individual cadmium selenide nanowires, and determine the nanowires absorption bandgap of 1.75 eV. This technique has high detection sensitivity. Potentially it will be able to measure absorption cross-section as small as 19 nm(2) per mu m for a focus laser spot of 1 mu m, and could be a general method to detect the absorption spectrum of individual quasi-one-dimensional nanomaterials.

However, a recent experiment showed that fission of Hg-180 following electron capture on Tl-180 is asymmetric. Purpose: We calculate potential-energy surfaces for a typical actinide nucleus and for 12 even isotopes in the range Hg-178-Hg-200, to investigate the similarities and differences of actinide compared to mercury potential surfaces and to what extent fission-fragment properties, in particular shell structure, relate to the structure of the static potential-energy surfaces. Methods: Potential-energy surfaces are calculated in the macroscopic-microscopic approach as functions of five shape coordinates for more than five million shapes. The structure of the surfaces is investigated by the use of an immersion technique. Results: We determine properties of minima, saddle points, valleys, and ridges between valleys in the five-dimensional shape-coordinate space. Along the mercury isotope chain the barrier heights and the ridge heights and their persistence with elongation vary significantly and show no obvious connection to possible fragment shell structure, in contrast to the actinide region, where there is a deep asymmetric valley extending from the saddle point to scission. Conclusions: The mechanism of asymmetric fission must be very different in the lighter proton-rich mercury isotopes compared to the actinide region and is apparently unrelated to fragment shell structure. Isotopes lighter than Hg-192 have the saddle point shielded from a deep symmetric valley by a significant ridge. The ridge vanishes for the heavier Hg isotopes, for which we would expect a qualitatively different asymmetry of the fragments.

The volume and surface coefficients share the same physical origin and their physical connection is used to extend the expansion with a curvature term. A possible generalization of the Wigner term is also suggested. This connection between coefficients is used to fit the experimental nuclear masses. The excellent fit obtained with a smaller number of parameters validates the assumed physical connections and the usefulness of the curvature term. C1 [Moretto, L. G.; Lake, P.

Koch, Volker Randrup, Jorgen TI Surface tension of quark matter in a geometrical approach SO PHYSICAL REVIEW C LA English DT Article ID STARS; MODEL; TRANSITION; NUCLEATION AB The surface tension of quark matter plays a crucial role for the possibility of quark matter nucleation during the formation of compact stellar objects, because it determines the nucleation rate and the associated critical size. However, this quantity is not well known and the theoretical estimates fall within a wide range, gamma(0) approximate to 5-300 MeV/fm(2). We show here that once the equation of state is available one may use a geometrical approach to obtain a numerical value for the surface tension that is consistent with the model approximations adopted. We illustrate this method within the two-flavor linear sigma model and the Nambu-Jona-Lasinio model with two and three flavors. Treating these models in the mean-field approximation, we find gamma(0) approximate to 7-30 MeV/fm(2). Such a relatively small surface tension would favor the formation of quark stars and may thus have significant astrophysical implications. We also investigate how the surface tension decreases towards zero as the temperature is raised from zero to its critical value.

We propose a new kinematic variable to isolate the WLWL scattering component in same-sign WW production at the LHC. Focusing on purely leptonic W decay channels, we show that it considerably improves the LHC capabilities to shed light on the electroweak symmetry breaking mechanism after collecting 100 fb(-1) of data at root s = 14 TeV. The new variable is less effective in the opposite-sign WW channel due to different background composition.

Further, the spin orientation of these photoelectrons in general can also be very different from that of the initial surface state and is controlled by the photon polarization. A rich set of predicted phenomena have recently been confirmed by spin- and angle-resolved photoemission experiments. C1 [Park, Cheol-Hwan] Univ Calif Berkeley, Dept Phys, Berkeley, CA 94720 USA.

We show, by directly calculating numerically the conductance fluctuations, that in the limit of very large system size and disorder strength, quantum transport becomes universal. However, a systematic deviation away from universality is obtained for realistic system parameters. By comparing our results to existing experimental data on 1/f noise, we suggest that many of the graphene samples studied to date are in a nonuniversal crossover regime of conductance fluctuations.

The energy position of this current wave is closely below the potential of the anodization treatment. Continued cycling or exchanging of the electrolyte causes depletion of this new feature. The O 1s and Fe 2p core-level X-ray photoelectron spectra (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectra of such conditioned hematite exhibit a chemical shift towards higher binding energies, in line with the general perception that anodization generates oxide species with dielectric properties. The valence band XPS and particularly the iron resonant valence band photoemission spectra, however, are shifted towards the opposite direction, that is, towards the Fermi energy, suggesting that hole doping on hematite has taken place during anodization. Quantitative analysis of the Fe 2p resonant valence band photoemission spectra shows that the spectra obtained at the Fe 2p absorption threshold are shifted by virtually the same energy as the anodization potential towards the Fermi energy. The tentative interpretation of this observation is that anodization forms a surface film on the hematite that is specific to the anodization potential.

These simple measurements allow us to map the density of states, providing evidence for the presence of a relatively small number of discrete electron traps at the band gap. We have taken advantage of the variety of TiO2 synthetic procedures that lead to well-defined morphologies (such as nanowires, nanocolumns, nanotubes, and nanoparticles) of anatase and rutile to investigate the nature of these electron traps. They derive from the structural disorder at the contact between neighboring crystalline nanoparticles. As expected, both their density and energetic location are highly dependent, not only on the crystalline structure (whether it is anatase or rutile), but also on the electrode morphology (i.e. the facets that meet at the grain boundaries). The trap density is also sensitive to pH changes and to the presence of some adsorbates. This variation of the number of traps with the electrolyte indicates that on one hand, an apparent electronic density of states is actually measured. On the other, it indicates that the traps are surface-related in agreement with their particular location at the perimeter of the grain boundaries. The effect of these traps on the observed electrode catalytic reactivity has also been studied. In the dark, it is found that they are directly involved in the electron transfer toward oxygen. In addition, under illumination, the trap states show a deleterious effect, favoring electron recombination.

Li et al., Nature (London) 468, 283 (2010); Y. Li et al., Nat. Phys. 8, 404 (2012)] in single-layer HgBa2CuO4+delta, which are often taken as evidence of the orbital-current origin of a pseudogap, I examine an alternative and assumption-free scenario constrained by first-principles calculations. I find that in addition to the common CuO2 band, a hybridized Hg-O state is present in the vicinity of the Fermi level and that it contributes to the low-energy ground state of this system. I calculate the spin-excitation spectrum based on the random-phase approximation in the superconducting state using a two-band model and show that a collective mode in the multiorbital channel arises at Q = 0. This mode splits in energy yet remains at Q similar to 0 as a pseudogap develops breaking both translational and time-reversal symmetries. The observations of the dynamical mode and static moment in the pseudogap state are in good accord with experimental observations. Detection of Hg-O band via optical study, or magnetic moment in the Hg-O layer will be tests of this calculation. C1 Los Alamos Natl Lab, Div Theoret, Los Alamos, NM 87545 USA.

TI High superconducting anisotropy and weak vortex pinning in Co-doped LaFeAsO SO PHYSICAL REVIEW B LA English DT Article ID HIGH-TEMPERATURE SUPERCONDUCTORS; LAYERED SUPERCONDUCTOR; CRITICAL CURRENTS; MAGNETIC-FIELDS; VORTICES; MOTION; STATE AB Here, we present an electrical transport study in single crystals of LaFe0.92Co0.08AsO (T-c similar or equal to 9.1 K) under high magnetic fields. In contrast to most of the previously reported Fe based superconductors, and despite its relatively low T-c, LaFe0.92Co0.08AsO shows a superconducting anisotropy which is comparable to those seen, for instance, in the cuprates or gamma(H) = H-c2(ab)/H-c2(c) = m(c)/m(ab) similar or equal to 9, where m(c)/m(ab) is the effective-mass anisotropy, although, in the present case and as in all Fe based superconductors, gamma -> 1 as T -> 0. Under the application of an external field, we also observe a remarkable broadening of the superconducting transition particularly for fields applied along the interplanar direction. Both observations indicate that the low dimensionality of LaFe1-xCoxAsO is likely to lead to a more complex vortex phase diagram when compared to the other Fe arsenides and consequently, to a pronounced dissipation associated with the movement of vortices in a possible vortex liquid phase. When compared to, for instance, F-doped compounds pertaining to the same family, we obtain rather small activation energies for the motion of vortices. This suggests that the disorder introduced by doping LaFeAsO with F is more effective in pinning the vortices than alloying it with Co. C1 [Li, G.; Grissonnanche, G.; Zhou, H.

TI Growth morphology and thermal stability of metal islands on graphene SO PHYSICAL REVIEW B LA English DT Article ID TOTAL-ENERGY CALCULATIONS; AUGMENTED-WAVE METHOD; BASIS-SET; GOLD AB We performed an experiment to study the thermal stability of metal on graphene. We show that Fe, Gd, Dy, and Eu on graphene exhibit island growth morphology. The 3D islands of Fe, Gd, and Dy show a small decrease in island density and an increase in the height/width aspect ratio upon thermal annealing. By contrast, coarsening of Eu islands to a close flat film is observed after annealing to 365 K. By investigating the fundamental interactions (i.e., adsorption energies and diffusion barriers) between the metal adatoms and graphene using ab initio calculations, we predict that most of the 3d and group 10 transition metals, noble metals, as well as rare earth metals on graphene should exhibit a 3D growth mode as observed in experiment. Most of the metal nanostructures on graphene should also be stable against aggregation. The 3D morphology and strong thermal stability of Fe, Co, Ni, Pt, and Gd islands on graphene can serve as good candidates for surface-supported catalysis applications.

TI Magnetic properties of the S=1/2 quasisquare lattice antiferromagnet CuF2(H2O)(2)(pyz) (pyz = pyrazine) investigated by neutron scattering SO PHYSICAL REVIEW B LA English DT Article ID 2-DIMENSIONAL HEISENBERG-ANTIFERROMAGNET; MAGNON DISPERSION; ZERO-TEMPERATURE AB We have performed elastic and inelastic neutron scattering experiments on single crystal samples of the coordination polymer compound CuF2(H2O)(2)(pyz) (pyz = pyrazine) to study the magnetic structure and excitations. The elastic neutron diffraction measurements indicate a collinear antiferromagnetic structure with moments oriented along the [0.7 0 1] real-space direction and an ordered moment of 0.60 +/- 0.03 mu(B)/Cu. This value is significantly smaller than the single-ion magnetic moment, reflecting the presence of strong quantum fluctuations. The spin wave dispersion from magnetic zone center to the zone boundary points (0.5 1.5 0) and (0.5 0 1.5) can be described by a two-dimensional Heisenberg model with a nearest-neighbor magnetic exchange constant J(2D) = 0.934 +/- 0.0025 meV. The interlayer interaction J(perp) in this compound is less than 1.5% of J(2D). The spin excitation energy at the (0.5 0.5 0.5) zone boundary point is reduced when compared to the (0.5 1 0.5) zone boundary point by similar to 10.3% +/- 1.4%. This zone boundary dispersion is consistent with quantum Monte Carlo and series expansion calculations for the S = 1/2 Heisenberg square lattice antiferromagnet, which include corrections for quantum fluctuations to linear spin wave theory.

Return-point memory loss is caused by motion of individual defects in kagome ice or of grain boundaries in square ice. In successive cycles, return-point memory is recovered rapidly in kagome ice. Memory is recovered more gradually in square ice due to the extended nature of the grain boundaries. Increasing the amount of quenched disorder increases the defect density but also enhances the return-point memory since the defects become trapped more easily.

The coated layer had a columnar microstructure with intercolumnar gaps between columnar grains. Nanosized pores could be observed around feather-like grains as well as inside the columnar grains. The main phase of all coated specimens was the tetragonal phase.

The thermal conductivity of coatings was successfully evaluated with the pulsed thermal imaging method using a combined sample of coatings and a substrate.

TI Genetic diversity within the genus Francisella as revealed by comparative analyses of the genomes of two North American isolates from environmental sources SO BMC GENOMICS LA English DT Article ID CHRONIC-GRANULOMATOUS-DISEASE; TULARENSIS SUBSPECIES TULARENSIS; FORMERLY YERSINIA-PHILOMIRAGIA; LIPOPOLYSACCHARIDE O-ANTIGEN; THIAMIN BIOSYNTHESIS; ESCHERICHIA-COLI; RIBOSOMAL-RNA; INOSITOL MONOPHOSPHATASE; BETA-GALACTOSIDASE; BACILLUS-SUBTILIS AB Background: Francisella tularensis is an intracellular pathogen that causes tularemia in humans and the public health importance of this bacterium has been well documented in recent history. Francisella philomiragia, a distant relative of F. tularensis, is thought to constitute an environmental lineage along with Francisella novicida. Nevertheless, both F. philomiragia and F. novicida have been associated with human disease, primarily in immune-compromised individuals. To understand the genetic relationships and evolutionary contexts among different lineages within the genus Francisella, the genome of Francisella spp. strain TX07-7308 was sequenced and compared to the genomes of F. philomiragia strains ATCC 25017 and 25015, F. novicida strain U112, and F. tularensis strain Schu S4. Results: The size of strain ATCC 25017 chromosome was 2,045,775 bp and contained 1,983 protein-coding genes. The size of strain TX07-7308 chromosome was 2,035,931 bp and contained 1,980 protein-coding genes. Pairwise BLAST comparisons indicated that strains TX07-7308 and ATCC 25017 contained 1,700 protein coding genes in common. NUCmer analyses revealed that the chromosomes of strains TX07-7308 and ATCC 25017 were mostly collinear except for a few gaps, translocations, and/or inversions. Using the genome sequence data and comparative analyses with other members of the genus Francisella (e. g., F. novicida strain U112 and F. tularensis strain Schu S4), several strain-specific genes were identified. Strains TX07-7308 and ATCC 25017 contained an operon with six open reading frames encoding proteins related to enzymes involved in thiamine biosynthesis that was absent in F. novicida strain U112 and F. tularensis strain Schu S4. Strain ATCC 25017 contained an operon putatively involved in lactose metabolism that was absent in strain TX07-7308, F. novicida strain U112, and F. tularensis strain Schu S4. In contrast, strain TX07-7308 contained an operon putatively involved in glucuronate metabolism that was absent in the genomes of strain ATCC 25017, F. novicida strain U112, and F. tularensis strain Schu S4. The polymorphic nature of polysaccharide biosynthesis/modification gene clusters among different Francisella strains was also evident from genome analyses. Conclusions: From genome comparisons, it appeared that genes encoding novel functions have contributed to the metabolic enrichment of the environmental lineages within the genus Francisella. The inability to acquire new genes coupled with the loss of ancestral traits and the consequent reductive evolution may be a cause for, as well as an effect of, niche selection of F. tularensis. Sequencing and comparison of the genomes of more isolates are required to obtain further insights into the ecology and evolution of different species within the genus Francisella.

Ramirez-Homs, Enrique TI Masses of a fourth generation with two Higgs doublets SO PHYSICAL REVIEW D LA English DT Article ID TREE-LEVEL UNITARITY; BOSON; MODEL; BOUNDS; SEARCH; LEP AB We use sampling techniques to find robust constraints on the masses of a possible fourth sequential fermion generation from electroweak oblique variables. We find that in the case of a light (115 GeV) Higgs from a single electroweak symmetry breaking doublet, inverted mass hierarchies are possible for both quarks and leptons, but a mass splitting more than MW in the quark sector is unlikely. We also find constraints in the case of a heavy (600 GeV) Higgs in a single doublet model. As recent data from the Large Hadron Collider hints at the existence of a resonance at 124.5 GeV and a single Higgs doublet at that mass is inconsistent with a fourth fermion generation, we examine a Type II two Higgs doublet model. In this model, there are ranges of parameter space where the Higgs sector can potentially counteract the effects of the fourth generation. Even so, we find that such scenarios produce qualitatively similar fermion mass distributions. C1 [Bellantoni, Leo] Fermilab Natl Accelerator Lab, Batavia, IL 60510 USA.

TI Next-to-leading order QCD predictions for W+1 jet and W+2 jet production with at least one b jet at the 7 TeV LHC SO PHYSICAL REVIEW D LA English DT Article AB We provide predictions for the production of a W boson in association with up to two jets including at least one b jet at next-to-leading order (NLO) in QCD at the CERN Large Hadron Collider with 7 TeV center-of-mass energy. Both exclusive and inclusive event cross section and b-jet cross sections are presented. The calculation is performed consistently in the five-flavor-number scheme where both q (q) over bar' and bq (q not equal b) initiated parton level processes are included at NLO QCD. We study the residual theoretical uncertainties of the NLO predictions due to the renormalization and factorization scale dependence, to the uncertainty from the parton distribution functions, and to the values of alpha(s) and the bottom-quark mass.

However, when the Z boson decays leptonically, all final state particles in this channel can be measured, allowing for accurate reconstructions of the Higgs mass and angular correlations. We determine the sensitivity of the Large Hadron Collider (LHC) running at center of mass energies of 8 and 14 TeV to Standard Model (SM) Higgs bosons with masses in the 120-130 GeV range. For the 8 TeV LHC, sensitivity to several times the SM cross section times branching ratio may be obtained with 20 inverse femtobarns of integrated luminosity, while for the 14 TeV LHC, the SM rate is probed with about 100 inverse femtobarns of integrated luminosity.

TI Measurement of branching fractions and rate asymmetries in the rare decays B -> K((*))l(+)l(-) SO PHYSICAL REVIEW D LA English DT Article AB In a sample of 471 x 10(6) B (B) over bar events collected with the BABAR detector at the PEP-II e(+)e(-) collider we study the rare decays B -> K((*))l(+)l(-), where l(+)l(-) is either e(+)e(-) or mu(+)mu(-). We report results on partial branching fractions and isospin asymmetries in seven bins of dilepton mass-squared. We further present CP and lepton-flavor asymmetries for dilepton masses below and above the J/psi resonance. We find no evidence for CP or lepton-flavor violation. The partial branching fractions and isospin asymmetries are consistent with the Standard Model predictions and with results from other experiments. C1 [Lees, J.

TI Implications of gauge-mediated supersymmetry breaking with vectorlike quarks and a similar to 125 GeV Higgs boson SO PHYSICAL REVIEW D LA English DT Article ID RENORMALIZATION-GROUP EQUATIONS; SOFTLY BROKEN SUPERSYMMETRY; BETA-FUNCTION; HADRON COLLIDERS; ROOT-S=7 TEV; MODEL; MSSM; MASSES; SUPERGRAVITY; FINITENESS AB We investigate the implications of models that achieve a Standard Model-like Higgs boson of mass near 125 GeV by introducing additional TeV-scale supermultiplets in the vectorlike 10 + (10) over bar representation of SU(5), within the context of gauge-mediated supersymmetry breaking. We study the resulting mass spectrum of superpartners, comparing and contrasting to the usual gauge-mediated and constrained minimal supersymmetric Standard Model scenarios, and discuss implications for LHC supersymmetry searches. This approach implies that exotic vectorlike fermions t(1,2)', b', and tau' should be within the reach of the LHC. We discuss the masses, the couplings to electroweak bosons, and the decay branching ratios of the exotic fermions, with and without various unification assumptions for the mass and mixing parameters. We comment on LHC prospects for discovery of the exotic fermion states, both for decays that are prompt and for those that are nonprompt on detector-crossing time scales.

TI Enhancement of the Curie temperature in NdBaCo2O5.5 by A-site Ca substitution SO PHYSICAL REVIEW B LA English DT Article ID SPIN-STATE TRANSITION; 112 LNBACO(2)O(5.50+/-DELTA); TRANSPORT; PRBACO2O5+DELTA; TB; GD; DY AB Layered cobaltites RBaCo2O5.5 (R = rare earth and Y) undergo a sequence of magnetic and electronic transitions between antiferromagnetic/ferrimagnetic/paramagnetic and insulating/paramagnetic metallic states with respective transition temperatures T-N (similar to 230-260 K) < T-C (similar to 250-290 K) < T-MI (similar to 360 K). We have synthesized a Nd1-xCaxBaCo2O5.5 series (0 <= x <= 0.2) of cation-[(Nd,Ca)/Ba]-ordered and oxygen vacancy-ordered materials and investigated them by neutron diffraction, magnetization, and electronic and thermal transport. We observe that upon Ca doping, T-N is decreasing to 0 for x = 0.1 and T-C is increasing and coincides with T-MI for x > 0.12, which weakly changes with Ca substitution from similar to 360 to similar to 340 K. This is the largest enhancement of T-C observed for these cobaltites. Unlike hole doping by adding oxygen, Ca doping does not disrupt the cation and oxygen vacancy orderings up to x = 0.20.

The Poincare patch is an example, but more general choices of b can be considered. We propose a geometric construction of H. We argue that H should contain the set C of causal curves with both endpoints on b. Yet H should not reach so far from the boundary that the CFT has insufficient degrees of freedom to describe it. This can be guaranteed by constructing a superset L of H from light-sheets off boundary slices and invoking the covariant entropy bound in the bulk. The simplest covariant choice is L = L+ boolean AND L-, where L+ (L-) is the union of all future-directed (past-directed) light-sheets. We prove that C = L, so the holographic domain is completely determined by our assumptions: H = C = L. In situations where local bulk operators can be constructed on b, H is closely related to the set of bulk points where this construction remains unambiguous under modifications of the CFT Hamiltonian outside of b. Our construction leads to a covariant geometric renormalization-group flow. We comment on the description of black hole interiors and cosmological regions via AdS/CFT.

TI Enhanced translational diffusion of confined water under electric field SO PHYSICAL REVIEW E LA English DT Article ID ICE NUCLEATION; DYNAMICS AB High resolution quasielastic neutron scattering measurements have been used to study the effects of applied electric field on the dynamics of water molecules confined in the pores of folded silica sheet material FSM-12 with an average pore diameter (apd) of 16 angstrom. In the absence of field, there is a significant slowing down of the water molecule diffusion as the temperature is lowered, in agreement with previous observations. The application of a moderate electric field of 2.5 kV/mm remarkably enhances the translational diffusion of water molecules. We interpret this as being due to a disruption of the hydrogen bonding by the electric field. This new observation suggests that existing theories valid at large electric field strengths may have to be corrected at moderate fields. C1 [Diallo, S.

In TIs based on the zinc-blende structure such as HgTe, the Fermi energy intersects the degenerate Gamma(8v) state so the insulating gap E-g between occupied and unoccupied bands vanishes. To achieve an insulating gap E-g > 0 critical for TI applications, one often needs to resort to structural manipulations such as structural symmetry lowering (e. g., Bi2Se3), strain, or quantum confinement. However, these methods have thus far opened an insulating gap of only <0.1 eV. Here we point out that there is an electronic rather than structural way to affect an insulating gap in a TI: if one can invert the spin-orbit levels and place Gamma(8v) below Gamma(7v) ("negative spin-orbit splitting"), one can realize band inversion (Delta(i) < 0) with a large insulating gap (E-g up to 0.5 eV). We outline design principles to create negative spin-orbit splitting: hybridization of d orbitals into p-like states. This general principle is illustrated in the "filled tetrahedral structures" (FTS) demonstrating via GW and density functional theory (DFT) calculations E-g > 0 with Delta(i) < 0, albeit in a metastable form of FTS.

Results from event-by-event simulations are compared with experimental data at both Relativistic Heavy Ion Collider and Large Hadron Collider energies. Fluctuations in the initial energy density come from not only the number of coherent soft interactions of overlapping nucleons but also incoherent semi-hard parton scatterings in each binary nucleon collision. Mini-jets from semi-hard parton scatterings are assumed to be locally thermalized through a Gaussian smearing and give rise to nonvanishing initial local flow velocities. Fluctuations in the initial flow velocities lead to harder transverse momentum spectra of final hadrons due to nonvanishing initial radial flow velocities. Initial fluctuations in rapidity distributions lead to expanding hot spots in the longitudinal direction and are shown to cause a sizable reduction of final hadron elliptic flow at large transverse momenta.

TI PTF 11kx: A Type Ia Supernova with a Symbiotic Nova Progenitor SO SCIENCE LA English DT Article ID WHITE-DWARF STAR; SN 2011FE; CIRCUMSTELLAR MATERIAL; SODIUM-ABSORPTION; COMPANION STAR; RS-OPHIUCHI; MASS; EVOLUTION; REMNANT; CHANNEL AB There is a consensus that type Ia supernovae (SNe Ia) arise from the thermonuclear explosion of white dwarf stars that accrete matter from a binary companion. However, direct observation of SN Ia progenitors is lacking, and the precise nature of the binary companion remains uncertain. A temporal series of high-resolution optical spectra of the SN Ia PTF 11kx reveals a complex circumstellar environment that provides an unprecedentedly detailed view of the progenitor system. Multiple shells of circumstellar material are detected, and the SN ejecta are seen to interact with circumstellar material starting 59 days after the explosion. These features are best described by a symbiotic nova progenitor, similar to RS Ophiuchi. C1 [Dilday, B.; Howell, D. A.; Parrent, J.

TI Exploring complexity with the Hohokam Water Management Simulation: A middle way for archaeological modeling SO ECOLOGICAL MODELLING LA English DT Article DE Archaeological simulation modeling; Complex adaptive systems; Agent-based modeling; Hohokam ID SOCIAL-SYSTEMS; GILA RIVER; SOUTHWEST; LANDSCAPE; ARIZONA AB The Hohokam Water Management Simulation is a simulation model constructed to explore the dynamics that underlie the long-term trajectory of the Hohokam, a people who lived in what is today Arizona (USA) and who built large-scale irrigation systems and operated them successfully for approximately 1000 years. The nature of the data available and the form of questions that the context prompts lead to a novel modeling approach that is described here. The core of the approach is the ability to shift the model's components along axes from highly detailed to very abstract, while pursuing a suite of related but distinct goals. The intent is to allow questions about the behavior of the entire socionatural system to be investigated to discern and explore complex system dynamics. The modeling framework and underlying theory is explicated, a (purely demonstrative) example is presented, and current work and future plans are discussed. (c) 2012 Elsevier B.V. All rights reserved.

TI Sum Frequency Generation Vibrational Spectroscopy of Colloidal Platinum Nanoparticle Catalysts: Disordering versus Removal of Organic Capping SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID PT(111) CRYSTAL-SURFACE; C-6 HYDROCARBONS; CYCLOHEXENE DEHYDROGENATION; STRUCTURE SENSITIVITY; HIGH-PRESSURES; SHAPE CONTROL; HYDROGENATION; SELECTIVITY; ADSORPTION; NANOCRYSTALS AB Recent work with nanoparticle catalysts shows that size and shape control on the nanometer scale influences reaction rate and selectivity. Sum frequency generation (SFG) vibrational spectroscopy is a powerful tool for studying heterogeneous catalysis because it enables the observation of surface intermediates during catalytic reactions. To control the size and shape of catalytic nanoparticles, an organic ligand was used as a capping agent to stabilize nanoparticles during synthesis. However, the presence of an organic capping agent presents two major challenges in SFG and catalytic reaction studies: it blocks a significant fraction of active surface sites and produces a strong signal that prevents the detection of reaction intermediates with SFG. Two methods for cleaning Pt nanoparticles capped with poly(vinylpyrrolidone) (PVP) are examined in this study:. solvent cleaning and UV cleaning. Solvent cleaning leaves more PVP intact and relies on disordering with hydrogen gas to reduce the SFG signal of PVP. In contrast, UV cleaning depends on nearly complete removal of PVP to reduce SFG signal. Both UV and solvent cleaning enable the detection of reaction intermediates by SFG. However, solvent cleaning also yields nanoparticles that are stable under reaction conditions, whereas UV cleaning results in aggregation during reaction. The results of this study indicate that solvent cleaning is more advantageous for studying the effects of nanoparticle size and shape on catalytic selectivity by SFG vibrational spectroscopy.

TI Molecular Dynamics Studies of Dislocations in CdTe Crystals from a New Bond Order Potential SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID CDZNTE RADIATION DETECTORS; MINIMUM ENERGY PATHS; ELASTIC BAND METHOD; ROOM-TEMPERATURE; SADDLE-POINTS; DEFORMATION AB Cd1-xZnxTe (CZT) crystals are the leading semiconductors for radiation detection, but their application is limited by the high cost of detector-grade materials. High crystal costs primarily result from property nonuniformity that causes low manufacturing yield. Although tremendous efforts have been made in the past to reduce Te inclusions/precipitates in CZT, this has not resulted in an anticipated improvement in material property uniformity. Moreover, it is recognized that in addition to Te particles, dislocation cells can also cause electric field perturbations and the associated property nonuniformities. Further improvement of the material, therefore, requires that dislocations in CZT crystals be understood and controlled. Here, we use a recently developed CZT bond order potential to perform representative molecular dynamics simulations to study configurations, energies, and mobilities of 29 different types of possible dislocations in CdTe (i.e., x = 1) crystals. An efficient method to derive activation free energies and activation volumes of thermally activated dislocation motion will be explored. Our focus gives insight into understanding important dislocations in the material and gives guidance toward experimental efforts for improving dislocation network structures in CZT crystals.

TI Effect of Electric Field on Water Confined in Graphite and Mica Pores SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID MOLECULAR-DYNAMICS; LIQUID WATER; DIELECTRIC-CONSTANT; PHASE-TRANSITIONS; SURFACE-TENSION; FLUIDS; VAPOR; SIMULATION; MODEL; ELECTROSTRICTION AB We examined the influence of external electric field on the vapor-liquid coexistence curve and on structural properties of TIP4P/2005 water confined in hydrophobic and hydrophilic pores using all-atom molecular dynamics simulations. While the electric field increases the critical temperature of bulk water, the effect is contrary on the confined water. We clearly observe that the critical temperature of confined water decreases with increasing field strength. The current work strongly indicates that using electric field results in a decrease in the saturated liquid phase density and increase in the saturated vapor phase density of the confined water and can be used to modulate the evaporation rate of water under confinement. The effect of an electric field on the confined fluids is more pronounced at higher temperature. We also report that the critical density Of water behaves differently in hydrophobic and hydrophilic pores. With increasing electric field, the critical density increases in hydrophobic pores; however, it is found to decrease in hydrophilic pores. We analyze the results using pair correlation :functions and orientational, tetrahedral, and hydrogen bond distributions. Our investigation indicates that the presence of an electric field enhances the coordination number N(r) of the bulk phase. In contrast, the presence of an electric field reduces N(r) Of the confined fluid. This is clearly reflected in the behavior of the critical temperature of bulk and confined water. Our structural analysis reveals that the application of an external field induces orientational order of dipole vector parallel to the field direction in bulk water, whereas its effects on dipole orientation is much less in confined systems. We also report that the hydrogen-bonding behavior in the vapor phase is responsible for the difference in critical density of water confined in hydrophobic and hydrophilic pores.

TI H-2-D-2 Exchange Kinetics in the Presence of H2S over Pd4S, Pd70Cu30, and Pd47Cu53 Surfaces SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID MULTI-TUBULAR PD; ELEVATED-TEMPERATURES; HYDROGEN PERMEATION; COMPOSITE MEMBRANE; ALLOY MEMBRANES; CU MEMBRANES; 1173 K; PALLADIUM; H-2; SEGREGATION AB H2S retards H-2 transport across Pd membranes used for H-2 separation by forming a Pd4S scale that has both low H2 dissociation activity and low H-atom permeability. As hydrogen purification membranes, alloys such as Pd70Cu30 and Pd47Cu53 are attractive alternatives to pure Pd due to their resistance to formation of bulk sulfides. Nonetheless, exposure to H2S can decrease the permeability of Pd70Cu30 and Pd47Cu53 membranes, presumably by poisoning the catalytic activity of their surfaces for H-2 dissociation. In this work, the effect of H2S on H-2 dissociation on Pd4S, Pd70Cu30, and Pd47Cu53 surfaces is investigated by rnicrokinetic analysis of H-2-D-2 exchange kinetics over Pd4S, Pd70Cu30, and Pd47Cu53 surfaces in the presence of varying concentrations of H2S at near-ambient H-2+H-2 pressure. We show that the rate of H-2-D-2 exchange over all three surfaces is significantly suppressed when H2S is added to H-2/D-2/Ar reactant mixtures and that the suppression of H-2-D-2 exchange increases with increasing H2S concentration. Microkinetic analysis of the H-2-D-2 exchange kinetics reveals that H2S decreases the rate of H-2-D-2 exchange by two distinct mechanisms: (1) increasing the intrinsic barrier to H-2 dissociation and (2) blocking H-2 dissociation sites.

TI Condensed-Phase and Oxidation Reaction Behavior of Ti/2B Foils in Varied Gaseous Environments SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID HIGH-TEMPERATURE SYNTHESIS; COMBUSTION SYNTHESIS; THIN-FILMS; TIB2; MECHANISM; SYSTEMS AB The effect of gaseous environment on self-propagating reactions in Ti/2B multilayer foils was studied. Multilayers with reactant layer periodicities from 50 to 3000 nm and a nominal stoichiometry of 1:2 Ti:B were grown using magnetron sputtering. Analysis through scanning transmission electron microscopy differential scanning calorimetry and X-ray diffraction revealed the as-deposited multilayers consisted of well-ordered layers of crystalline Ti and amorphous B with the amount of intermixed material negligibly affecting the exothermicity. Propagation rate testing was performed at varied vacuum pressures and studied by high-speed imaging. Propagation rates for foils with bilayer thicknesses 666 nm or thinner did not exhibit a pressure dependency, while foils with bilayer thicknesses 857 nm and larger did. The latter thick-bilayer foils would not propagate below a characteristic pressure. After reaction Auger electron spectroscopy revealed O penetration in the thicker bilayer designs and incomplete mixing of Ti and B, while the thinner bilayer foils were uniformly converted to single-phase, hexagonal TiB2. Increased air pressure was found to promote the propagating reaction of the thicker bilayer designs, likely due to increased heat release from oxidation that promotes intermixing and reaction between Ti and B.

In this study, the beta-relaxational dynamics of the two proteins, IPPase and lysozyme, are compared in the 10 Ps to 0.5 ns time interval using quasi-elastic neutron scattering (QENS). Both of the protein dynamics show a characteristic logarithmic-like decay in the intermediate scattering function (ISF) of the hydrogen atoms. Distinguishable dynamical behavior found between two proteins reveals local flexibility and conformational substates unique to oligomeric structures. Moreover, the temperature dependence of the mean square displacement (MSD) of the hydrogen atoms in protein molecules, which is a traditional way to determine the "softness" of the protein molecule, is measured and shows no difference for the two proteins: C1 [Chu, Xiang-qiang; Weiss, Kevin L.; Mamontov, Eugene; Coates, Leighton] Oak Ridge Natl Lab, Neutron Scattering Sci Div, Oak Ridge, TN 37831 USA.

In this work, 3-20 wt % microcrystalline cellulose (Avicel) solutions were treated with 1-ethyl-3-methylimidazohum acetate [C(2)mim][OAc]) and a mixture of [C(2)mim][OAc] with the nonsolvent dimethyl sulfoxide (DMSO) at different temperatures. The dissolution process was slowed by decreasing the temperature and increasing cellulose loading, and was further retarded by addition of DMSO, enabling in-depth examination of the intermediate stages of dissolution. Results' show that the cellulose I lattice expands and distorts prior to full dissolution in [C(2)rniin][OAc] and that upon precipitation the former:, structure leads to a less ordered intermediate structure, whereas fully dissolved cellulose leads to a mixture of cellulose II and amorphous cellulose. Enzymatic hydrolysis was more rapid for the intermediate Structure (crystallinity = 0.34) than for Cellulose II (crystallinity = 0.54).

TI Enhancement of critical current density in superconducting/magnetic multilayers with slow magnetic relaxation dynamics and large magnetic susceptibility SO PHYSICAL REVIEW B LA English DT Article ID MANGANESE ALLOYS; VORTEX LATTICE; SPIN-GLASSES; RARE-EARTH; SUPERCONDUCTOR; ERNI2B2C; CHAIN; COEXISTENCE; ANISOTROPY; COMPOUND AB We propose to use a superconductor- magnet multilayer structure to achieve high critical current density by invoking the polaronic mechanism of pinning. The magnetic layers should have large magnetic susceptibility to enhance the coupling between the vortices and magnetization in those layers. The relaxation of the magnetization should be slow. When the velocity of vortices is low, they are dressed by nonuniform magnetization and move as polarons. In this case, the viscosity of vortices, which is proportional to the magnetic relaxation time, is enhanced significantly. As the velocity increases, the polarons dissociate and the viscosity drops to the usual Bardeen-Stephen value, resulting in a jump in the I-V curve. Experimentally the jump shows up as a depinning transition and the corresponding current at the jump is the depinning current. For Nb and an appropriate magnet multilayer structure, we estimate the critical current density J(c) similar to 10(9) A/m(2) at magnetic field B approximate to 1 T.

CA CDF Collaboration TI Measurement of the WZ cross section and triple gauge couplings in p(p)over-bar collisions at root s=1.96 TeV SO PHYSICAL REVIEW D LA English DT Article ID QCD AB This article describes the current most precise measurement of the WZ production cross section as well as limits on anomalous WWZ couplings at a center-of-mass energy of 1.96 TeV in proton-antiproton collisions for the Collider Detector at Fermilab (CDF). WZ candidates are reconstructed from decays containing three charged leptons and missing energy from a neutrino, where the charged leptons are either electrons or muons. Using data collected by the CDF II detector (7.1 fb(-1) of integrated luminosity), 63 candidate events are observed with the expected background contributing 8 +/- 1 events. The measured total cross section sigma(p (p) over bar -> WZ) = 3.93(-0.53)(+0.60)(stat)(-0.46)(+0.59)(syst) pb is in good agreement with the standard model prediction of 3.50 +/- 0.21. The same sample is used to set limits on anomalous WWZ couplings.

TI Non-classical light generated by quantum-noise-driven cavity optomechanics SO NATURE LA English DT Article ID INDUCED TRANSPARENCY; RADIATION-PRESSURE; GROUND-STATE; REDUCTION AB Optomechanical systems(1), in which light drives and is affected by the motion of a massive object, will comprise a new framework for nonlinear quantum optics, with applications ranging from the storage(2-4) and transduction(5,6) of quantum information to enhanced detection sensitivity in gravitational wave detectors(7,8). However, quantum optical effects in optomechanical systems have remained obscure, because their detection requires the object's motion to be dominated by vacuum fluctuations in the optical radiation pressure; so far, direct observations have been stymied by technical and thermal noise. Here we report an implementation of cavity optomechanics(9,10) using ultracold atoms in which the collective atomic motion is dominantly driven by quantum fluctuations in radiation pressure. The back-action of this motion onto the cavity light field produces ponderomotive squeezing(11,12). We detect this quantum phenomenon by measuring sub-shot-noise optical squeezing. Furthermore, the system acts as a low-power, high-gain, nonlinear parametric amplifier for optical fluctuations, demonstrating a gain of 20 dB with a pump corresponding to an average of only seven intracavity photons. These findings may pave the way for low-power quantum optical devices, surpassing quantum limits on position and force sensing(13,14), and the control and measurement of motion in quantum gases.

TI Room-temperature ferroelectricity in supramolecular networks of charge-transfer complexes SO NATURE LA English DT Article ID IONIC PHASE-TRANSITION; TETRATHIAFULVALENE-CHLORANIL; MOLECULAR-CRYSTAL; STACK AB Materials exhibiting a spontaneous electrical polarization(1,2) that can be switched easily between antiparallel orientations are of potential value for sensors, photonics and energy-efficient memories. In this context, organic ferroelectrics(3,4) are of particular interest because they promise to be lightweight, inexpensive and easily processed into devices. A recently identified family of organic ferroelectric structures is based on intermolecular charge transfer, where donor and acceptor molecules co-crystallize in an alternating fashion known as a mixed stack(5-8): in the crystalline lattice, a collective transfer of electrons from donor to acceptor molecules results in the formation of dipoles that can be realigned by an external field as molecules switch partners in the mixed stack. Although mixed stacks have been investigated extensively, only three systems are known(9,10) to show ferroelectric switching, all below 71 kelvin. Here we describe supramolecular charge-transfer networks that undergo ferroelectric polarization switching with a ferroelectric Curie temperature above room temperature. These polar and switchable systems utilize a structural synergy between a hydrogen-bonded network and charge-transfer complexation of donor and acceptor molecules in a mixed stack. This supramolecular motif could help guide the development of other functional organic systems that can switch polarization under the influence of electric fields at ambient temperatures.

TI Specification, annotation, visualization and simulation of a large rule-based model for ERBB receptor signaling SO BMC SYSTEMS BIOLOGY LA English DT Article DE Systems biology; Epidermal growth factor (EGF) receptor (EGFR); Rule-based modeling; Temporal phosphoproteomics ID GROWTH-FACTOR RECEPTOR; SYSTEMS BIOLOGY; REACTION NETWORKS; KINETIC-MODELS; EARLY EVENTS; TRANSDUCTION; PATHWAYS; DYNAMICS; RESOURCE; PHOSPHORYLATION AB Background: Mathematical/computational models are needed to understand cell signaling networks, which are complex. Signaling proteins contain multiple functional components and multiple sites of post-translational modification. The multiplicity of components and sites of modification ensures that interactions among signaling proteins have the potential to generate myriad protein complexes and post-translational modification states. As a result, the number of chemical species that can be populated in a cell signaling network, and hence the number of equations in an ordinary differential equation model required to capture the dynamics of these species, is prohibitively large. To overcome this problem, the rule-based modeling approach has been developed for representing interactions within signaling networks efficiently and compactly through coarse-graining of the chemical kinetics of molecular interactions. Results: Here, we provide a demonstration that the rule-based modeling approach can be used to specify and simulate a large model for ERBB receptor signaling that accounts for site-specific details of protein-protein interactions. The model is considered large because it corresponds to a reaction network containing more reactions than can be practically enumerated. The model encompasses activation of ERK and Akt, and it can be simulated using a network-free simulator, such as NFsim, to generate time courses of phosphorylation for 55 individual serine, threonine, and tyrosine residues. The model is annotated and visualized in the form of an extended contact map. Conclusions: With the development of software that implements novel computational methods for calculating the dynamics of large-scale rule-based representations of cellular signaling networks, it is now possible to build and analyze models that include a significant fraction of the protein interactions that comprise a signaling network, with incorporation of the site-specific details of the interactions. Modeling at this level of detail is important for understanding cellular signaling.

TI Effect of Metal Ions on Photoluminescence, Charge Transport, Magnetic and Catalytic Properties of All-Inorganic Colloidal Nanocrystals and Nanocrystal Solids SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID DOPED SEMICONDUCTOR NANOCRYSTALS; MN/CDSE QUANTUM DOTS; HYDROGEN-GENERATION; CDSE NANOCRYSTALS; SURFACE LIGANDS; SEEDED GROWTH; EXCHANGE; CDTE; INVERSION; PROSPECTS AB Colloidal semiconductor nanocrystals (NCs) provide convenient "building blocks" for solution processed solar cells, light emitting devices, photocatalytic systems, etc The use of inorganic ligands for colloidal NCs dramatically improved inter-NC charge transport, enabling fast progress in NC-based devices. Typical inorganic ligands (e g, Sn2S64-, S2-) are represented by negatively charged ions that bind covalently to electrophilic metal surface sites. The binding of inorganic charged species to the NC surface provides electrostatic stabilization of NC colloids in polar solvents without introducing insulating barriers between NCs. In this work we show that cationic species needed for electrostatic balance of NC surface charges can also be employed for engineering almost every property of all-inorganic NCs and NC solids, including photoluminescence efficiency, electron mobility, doping, magnetic susceptibility, and electrocatalytic performance. We used a suite of experimental techniques to elucidate the impact of various metal ions on the characteristics of all inorganic NCs and developed strategies for engineering and optimizing NC-based materials C1 [Nag, Angshuman; Chung, Dae Sung; Dolzhnikov, Dmitriy S.; Talapin, Dmitri V.] Univ Chicago, Dept Chem, Chicago, IL 60637 USA.

TI Vacuum-Deposited Small-Molecule Organic Solar Cells with High Power Conversion Efficiencies by Judicious Molecular Design and Device Optimization SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID POLYMER PHOTOVOLTAIC CELLS; OPEN-CIRCUIT VOLTAGE; THIN-FILMS; SPECTROSCOPIC ELLIPSOMETRY; PHASE-SEPARATION; ACCEPTOR DYES; PERFORMANCE; INTERLAYER; DONORS; MORPHOLOGY AB Three new tailor-made molecules (DPDCTB, DPDCPB, and DTDCPB) were strategically designed and convergently synthesized as donor materials for small-molecule organic solar cells. These compounds possess a donor-acceptor-acceptor molecular architecture, in which various electron-donating moieties are connected to an electron-withdrawing dicyanovinylene moiety through another electron-accepting 2,1,3-benzothiadiazole block. The molecular structures and crystal packings of DTDCPB and the previously reported DTDCTB were characterized by single crystal X-ray crystallography. Photophysical and electrochemical properties as, well as energy levels of this series of donor molecules were thoroughly investigated, affording clear structure property relationships. By delicate manipulation of the trade-off between the photovoltage and the photocurrent via molecular structure engineering together with device optimizations, which included fine-tuning the layer thicknesses and the donor acceptor blended ratio in the bulk heterojunction layer, vacuum deposited hybrid planar mixed heterojunction devices utilizing DTDCPB as the donor and C-70 as the acceptor showed the best performance with a power conversion efficiency (PCE) of 6.6 +/- 0.2% (the highest PCE of 6.8%), along with an open circuit voltage (V-oc) of 0.93 +/- 0.02 V, a short-circuit current density (J(sc)) of 13.48 +/- 0.27 inA/cm(2), and a fill factor (FF) of 0.53 +/- 0.02, under 1 sun (100 mW/cm(2)) AM 1.5G simulated solar illumination.

Soft X-ray reveals directly the valence states of Fe 3d electrons in the vicinity of Fermi level, which is sensitive to the local lattice distortion, but more importantly offers detailed information on the evolution of electronic states at different electrochemical stages. The soft X-ray spectra of LixFePO4 nanoparticles evolve vividly with the (de)lithiation level. The spectra fingerprint the (de)lithiation process with rich information on Li distribution, valency, spin states, and crystal field. The high resolution spectra reveal a subtle but critical deviation from two-phase transformation in our electrochemically prepared samples. In addition, we performed both first principles calculations and multiplet simulations of the spectra and quantitatively determined the 3d valence states that are completely redistributed through (de)lithiation. This electronic reconfiguration was further verified by the polarization-dependent spectra collected on LiFePO4 single crystals, especially along the lithium diffusion direction. The evolution of the 3d states is overall consistent with the local lattice distortion and provides a fundamental picture of the (de)lithiation effects on electronic structure in the LixFePO4 system.

We use a chemical reaction, such as a disproportionation redox reaction, to generate dilute zerovalent metal atoms in a refluxing solution, which intercalate into the layered Bi2Se3 structure. The zerovalent nature of the intercalant allows superstoichiometric intercalation of metal atoms such as Ag, Au, Co, Cu, Fe, In, Ni, and Sn. We foresee the impact of this methodology in establishing novel fundamental physical behaviors and in possible energy applications.

Members of the Gram-positive bacterial genus Caldicellulosiruptor are anaerobic thermophiles with optimum growth temperatures between 65 degrees C and 78 degrees C and are the most thermophilic cellulolytic organisms known. In fact, they efficiently use biomass non-pretreated as their sole carbon source and in successive rounds of application digest 70% of total switchgrass substrate. The ability to genetically manipulate these organisms is a prerequisite to engineering them for use in conversion of these complex substrates to products of interest as well as identifying gene products critical for their ability to utilize non-pretreated biomass. Here, we report the first example of DNA transformation of a member of this genus, C. bescii. We show that restriction of DNA is a major barrier to transformation (in this case apparently absolute) and that methylation with an endogenous unique alpha-class N4-Cytosine methyltransferase is required for transformation of DNA isolated from E. coli. The use of modified DNA leads to the development of an efficient and reproducible method for DNA transformation and the combined frequencies of transformation and recombination allow marker replacement between non-replicating plasmids and chromosomal genes providing the basis for rapid and efficient methods of genetic manipulation.

In this system, directed assembly is guided by the periodic moire structure of the buckled graphene sheet. Behavior is analyzed utilizing both scanning tunneling microscopy and atomistic lattice-gas modeling together with kinetic Monte Carlo simulation. We elucidate the kinetics of NC nucleation and growth, specifically assessing the coverage dependence of the NC density and height distribution. In addition, we provide a detailed characterization of the development of short-range spatial order within the NC array, identifying a tendency for row formation.

However, sometimes the broken symmetries may blend with the invariant symmetries to lead to mysterious emergent phases. The heavy fermion metal URu2Si2 is one such example, where the order parameter responsible for a second- order phase transition at T-h=17.5 K has remained a long- standing mystery. Here we propose via ab- initio calculation and effective model that a novel spin- orbit density wave in the f- states is responsible for the hidden- order phase in URu2Si2. The staggered spin- orbit order spontaneously breaks rotational, and translational symmetries while time- reversal symmetry remains intact. Thus it is immune to pressure, but can be destroyed by magnetic field even at T=0 K, that means at a quantum critical point. We compute topological index of the order parameter to show that the hidden order is topologically invariant. Finally, some verifiable predictions are presented.

If an IDP could somehow be divided into smaller fragments and reconstructed later, theoretical and spectroscopic studies could probe its conformational variability in detail. Here, we used replica molecular-dynamics simulations and network theory to explore whether such a divide-and-conquer strategy is feasible for alpha-synuclein, a prototypical IDP. We characterized the conformationar variability of alpha-synuclein by conducting >100 unbiased all-atom molecular-dynamics simulations, for a total of >10 mu s of trajectories. In these simulations, alpha-synuclein formed a heterogeneous ensemble of collapsed coil states in an aqueous environment. These states were stabilized by heterogeneous contacts between sequentially distant regions. We find that alpha-synuclein contains residual secondary structures in the collapsed states, and the heterogeneity in the collapsed state makes it feasible to split alpha-synuclein into sequentially contiguous minimally interacting fragments. This study reveals previously unknown characteristics of alpha-synuclein and provides a new (to our knowledge) approach for studying other IDPs.

Process Development for Catalytic Gasification of Algae Feedstocks SO INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH LA English DT Article ID SUPERCRITICAL WATER AB Through the use of a metal catalyst, gasification of wet algae slurries can be accomplished with high levels of carbon conversion to gas at relatively low temperature (350 degrees C). In a pressurized-water environment (20 MPa), near-total conversion of the organic structure of the algae to gases has been achieved in the presence of a supported ruthenium metal catalyst. The process is essentially steam reforming, as there is no added oxidizer or reagent other than water. In addition, the gas produced is a medium-heating value gas due to the synthesis of high levels of methane, as dictated by thermodynamic equilibrium. As opposed to earlier work, biomass trace components were removed by processing steps so that they did not cause processing difficulties in the fixed catalyst bed tubular reactor system. As a result, the algae feedstocks, even those with high ash contents, were much more reliably processed without plugging the feeding systems or the fixed catalyst bed. High conversions were obtained even with high slurry concentrations. Consistent catalyst operation in these short-term tests suggested good stability and minimal poisoning effects. High methane content in the product gas was noted with significant carbon dioxide captured in the aqueous byproduct in combination with alkali constituents and the ammonia byproduct derived from proteins in the algae. High conversion of algae to gas products was found with low levels of byproduct water contamination and low to moderate loss of carbon in the mineral separation step. Further development is required to demonstrate protection of the catalyst bed from sulfur poisoning.

For two wires, the physical properties are governed by a single effective Luttinger parameter for each of the charge and spin sectors. We present numerical density-matrix-renormalization-group calculations of the conductance of a junction of two chains of interacting spinless fermions with different interaction strengths, obtained using a recently developed method [Phys. Rev. Lett. 105, 226803 (2010)]. The numerical results show very good agreement with the analytical predictions. For three spinless wires (i.e., a Y junction) we analytically determine the full phase diagram and compute all fixed-point conductances as a function of the three Luttinger parameters.

Prior studies have reported the successful fabrication of high-k, thin-film ferroelectrics with aspect ratios (diameter/thickness) < 1000; however, devices with aspect ratios > 10(4)-10(5) are necessary to meet the large-capacitive requirements in pulsed-power applications such as the inverters in hybrid electric vehicles (HEVs). It is also widely accepted that the breakdown field of thin films decreases logarithmically with an increase in the aspect ratio (area) due to the increased probability of producing a defect spot. These observations raise an important question: can we fabricate ferroelectric high-k film capacitors that have large aspect ratio and can sustain high fields? Here we report the fabrication and characterization of Pb0.92La0.08Zr0.52Ti0.48O3 thin-film capacitors with aspect ratios > 10(4) that can be operated at similar to 1MV cm(-1) and are suitable for embedded passives in HEVs. Dielectric spectroscopy showed a low-frequency anomalous relaxation behaviour in large-aspect-ratio heterostructure, which was analysed and interpreted using an equivalent circuit model. The measured anomalous relaxation behaviour was de-convoluted using the model to obtain the actual material response. High capacitances (1-5 mu F) and energy densities of (similar to 9J cm(-3)) were routinely measured in these high-aspect-ratio films.

However, our recent experiments on La0.5Ca0.5MnO3 demonstrated the limitation of these factors in explaining the radical difference between the magneto-transport properties of bulk and nanocrystalline forms. While bulk La0.5Ca0.5MnO3 exhibits insulator character (4-300 K) and an anti-ferromagnetic-ferromagnetic transition at 200 K, the nanocrystalline form stabilizes in a metallic ferromagnetic phase (4-300 K). This is counter-intuitive since large Jahn-Teller distortion, which promotes anti-ferromagnetism or insulator character, exists in the nanocrystals too (as indicated by x-ray diffraction results). In this work, we resolve this paradox by considering the role of structural disorder. Employing x-ray absorption spectroscopy, we establish that the disorder in inter-octahedral coupling is enhanced by 57% in the nanocrystals, as the octahedral units are randomly oriented with respect to each other. This orientational disorder promotes metallic ferromagnetism by destroying the stringent orbital ordering that is needed for anti-ferromagnetism and the co-operative nature of the orbital order.

Nevertheless, animals thrive around vents, some of which live near the known limits of animal thermotolerance. Paralvinella sulfincola, an extremely thermotolerant vent polychaete, and Paralvinella palmiformis, a cooler-adapted congener, are found along the Juan de Fuca Ridge in the northwestern Pacific. We conducted shipboard high-pressure thermotolerance experiments on both species to characterize the physiological adaptations underlying P. sulfincola's pronounced thermotolerance. Quantitative proteomics, expressed sequence tag (EST) libraries and glutathione assays revealed that P. sulfincola (i) exhibited an upregulation in the synthesis and recycling of glutathione with increasing temperature, (ii) downregulated nicotinamide adenine dinucleotide (NADH) and succinate dehydrogenases (key enzymes in oxidative phosphorylation) with increasing temperature, and (iii) maintained elevated levels of heat shock proteins (HSPs) across all treatments. In contrast, P. palmiformis exhibited more typical responses to increasing temperatures (e. g. increasing HSPs at higher temperatures). These data reveal differences in how a mesotolerant and extremely thermotolerant eukaryote respond to thermal stress, and suggest that P. sulfincola's capacity to mitigate oxidative stress via increased synthesis of antioxidants and decreased flux through the mitochondrial electron transport chain enable pronounced thermotolerance. Ultimately, oxidative stress may be the key factor in limiting all metazoan thermotolerance.

TI Photochemical Grafting of Organic Alkenes to Single-Crystal TiO2 Surfaces: A Mechanistic Study SO LANGMUIR LA English DT Article ID EXCITON-MEDIATED HYDROSILYLATION; NANOCRYSTALLINE ANATASE TIO2; HYDROGEN-TERMINATED SILICON; TRAPPED HOLES; WORK FUNCTION; THIN-FILMS; HETEROGENEOUS PHOTOCATALYSIS; BIOMOLECULAR INTERFACES; TIO2(110) SURFACE; DIAMOND SURFACES AB The UV-induced photochemical grafting of terminal alkenes has emerged as a versatile way to form molecular layers on semiconductor surfaces. Recent studies have shown that grafting reactions can be initiated by photoelectron emission into the reactant liquid as well as by excitation across the semiconductor band gap, but the relative importance of these two processes is expected to depend on the nature of the semiconductors, the reactant alkene and the excitation wavelength. Here we report a study of the wavelength-dependent photochemical grafting of alkenes onto single-crystal TiO2 samples. Trifluoroacetamide-protected 10-aminododec-1-ene (TFAAD), 10-N-BOC-aminodec-1-ene (t-BOC), and 1-dodecene were used as model alkenes. On rutile (110), photons with energy above the band gap but below the expected work function are not effective at inducing grafting, while photons with energy sufficient to induce electronic transitions from the TiO2 Fermi level to electronic acceptor states of the reactant molecules induce grafting. A comparison of rutile (110), rutile (001), anatase (001), and anatase (101) samples shows slightly enhanced grafting for rutile but no difference between crystal faces for a given crystal phase. Hydroxylation of the surface increases the reaction rate by lowering the work function and thereby facilitating photoelectron ejection into the adjacent alkene. These results demonstrate that photoelectron emission is the dominant mechanism responsible for grafting when using short-wavelength (similar to 254 nm) light and suggest that photoemission events beginning on mid-gap states may play a crucial role.

In this paper, a comprehensive physicochemical and textural characterization of HTC materials obtained using four different precursors, namely, xylose, glucose, sucrose, and starch, is presented. The development of porosity in the prepared HTC materials as a function of thermal treatment (under an inert atmosphere) was specifically monitored using N-2 and CO2 sorption analysis. The events taking place during the thermal treatment process were studied by a combined thermogravimetric/infrared (TGA-IR) measurement. Interestingly, these inexpensive biomass-derived carbon materials show good selectivity for CO2 adsorption over N-2 (CO2/N-2 selectivity of 20 at 273 K, 1 bar and 1:1 gas composition). Furthermore, the elemental composition, morphologies, degree of structural order, surface charge, and functional groups are also investigated.

In the first two steps of the pathway, MEP is produced from the central metabolic intermediates pyruvate and glyceraldehyde 3-phosphate via 1-deoxy-D-xylulose 5-phosphate (DXP) by the activity of the enzymes DXP synthase (DXS) and DXP reductoisomerase (DXR). Because the MEP pathway is absent from humans, it was proposed as a promising new target to develop new antibiotics. However, the lethal phenotype caused by the deletion of DXS or DXR was found to be suppressed with a relatively high efficiency by unidentified mutations. Here we report that several mutations in the unrelated genes aceE and ribB rescue growth of DXS-defective mutants because the encoded enzymes allowed the production of sufficient DXP in vivo. Together, this work unveils the diversity of mechanisms that can evolve in bacteria to circumvent a blockage of the first step of the MEP pathway.

The products were characterized by X-ray powder diffraction, scanning and transmission electron microscopy, high-resolution transmission electron microscopy, energy dispersive spectroscopy analysis, N-2 adsorption and UV-vis diffuse reflectance spectroscopy. The shell of all hollow spheres is composed of single-crystal metal sulfide nanoparticles and the shell thickness can be readily controlled by changing the deposition time. These hollow microspheres are envisioned to have broad applications in catalysis, Li-ion batteries, microreactors, biomedicines, etc. As an example, here, we demonstrate that the prepared CdS and ZnS hollow sub-micrometer spheres are excellent photocatalysts with higher photodegradation efficiency of potential polluting agents than that of commercial CdS, ZnS and TiO2 P25 under visible light and UV light illumination, respectively.

The maximum PtMo turnover frequencies were observed for Mo weight loadings of 1.4% and 1.2% when supported on Al2O3 and SiO2, respectively. Above these loadings, the exposed Pt surface area as measured by hydrogen chemisorption was reduced. The hydrogen chemisorption values and X-ray absorption spectroscopy of the reduced catalysts indicate the formation of PtMo bimetallic particles that are surface rich in Mo, yet increases in Pt-Mo coordination do not correlate with changes in turnover frequency, and most of the Mo is present in the form of Mo-oxide. The decrease in TOF from the optimum Mo loading is attributed to differences in surface coverages of intermediates that are observed in the changing reaction orders and ascribed to the interplay between the PtMo alloy metal function and the promotion of water activation by MoOx promotion of the support. The decreased Pt dispersion and CO binding energy of Pt-Mo catalysts result in CO reaction orders as high as 0.8 at 300 degrees C, and Mo addition resulted in apparent activation energies which were 20-40 kJ/mol lower than the Mo free samples. The promoted catalysts achieved higher TOF than Pt/CeO2 when calculated at or below 250 degrees C with 6.8% CO, 8.5% CO2, 21.9% H2O. 37.4% H-2, and balance Ar at 1 atm total pressure.

Tungsten based support assigned WCctabr has been synthesized by polycondensation of resorcinol and formaldehyde in the presence of CTABr surfactant. Support assigned WCwo(3) was synthesized from resorcinol/formaldehyde gel, using WO3 nanoparticles as starting material. Supporting materials have been characterized by BET (Brunauer, Emmett and Teller) technique and determined values of surface area were 80 m(2) g(-1) for WCctabr and 175 m(2) g(-1) for WCWO3. Platinum nanocatalysts (10% Pt) at tungsten based supports have been prepared by borohydride reduction method. Both synthesized supports and catalysts have been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS) techniques. Cyclic voltammetry was applied for determination of electrochemically active surface area (40 m2 g(-1) for Pt/WCWO3 and 55 m(2) g(-1) for Pt/WCctabr). Oxygen reduction reaction has been studied by cyclic voltammetry and linear sweep voltammetry at rotating disc electrode (RDE). These catalysts exhibited better catalytic activity, expressed in terms of kinetic current density per real surface area at the constant potential and better stability, in comparison with Pt/C catalyst, as well as with already reported catalytic activity values for Pt catalysts on tungsten based supports.

The linewidth data set was employed in spectral fits of N-2 RCARS spectra recorded in binary mixtures of N-2 and H-2 at calibrated temperature conditions up to 661 K using a standard nanosecond RCARS setup. In this region, the set shows a deviation of less than 2% in comparison with thermocouples. The results provide useful knowledge for the applicability of N-2 CARS thermometry on the fuel-side of H-2 diffusion flames. (C) 2012 American Institute of Physics.

TI Hydration structures of U(III) and U(IV) ions from ab initio molecular dynamics simulations SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID DENSITY-FUNCTIONAL THEORY; TOTAL-ENERGY CALCULATIONS; AQUO CHLORO COMPLEXES; AUGMENTED-WAVE METHOD; AQUEOUS-SOLUTION; 1ST PRINCIPLES; TETRAVALENT ACTINIDES; BASIS-SET; HYDROLYSIS; WATER AB We apply DFT+U-based ab initio molecular dynamics simulations to study the hydration structures of U(III) and U(IV) ions, pertinent to redox reactions associated with uranium salts in aqueous media. U(III) is predicted to be coordinated to 8 water molecules, while U(IV) has a hydration number between 7 and 8. At least one of the innershell water molecules of the hydrated U(IV) complex becomes spontaneously deprotonated. As a result, the U(IV)-O pair correlation function exhibits a satellite peak at 2.15 angstrom associated with the shorter U(IV)-(OH-) bond. This feature is not accounted for in analysis of extended x-ray absorption fine structure and x-ray adsorption near edge structure measurements, which yield higher estimates of U(IV) hydration numbers. This suggests that it may be useful to include the effect of possible hydrolysis in future interpretation of experiments, especially when the experimental pH is close to the reported hydrolysis equilibrium constant value.

The coadsorbed H2O (OH) species slightly increase the CO2 adsorption energies, primarily through formation of hydrogen bonds, and create new binding configurations that are not present on the anhydrous surface. Proton transfer reactions to CO2 with formation of bicarbonate and carbonic acid species were investigated and found to have barriers in the range 6.1-12.8 kcal/mol, with reactions involving participation of two or more water molecules or OH groups having lower barriers than reactions involving a single adsorbed water molecule or OH group. The reactions to form the most stable adsorbed formate and bicarbonate species are exothermic relative to the unreacted adsorbed CO2 and H2O (OH) species, with formation of the bicarbonate species being favored. These results are consistent with single crystal measurements which have identified formation of bicarbonate-type species following coadsorption of CO2 and water on rutile (110).

TI A generalized kinetic model for heterogeneous gas-solid reactions SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID OXIDATION; METALS AB We present a generalized kinetic model for gas-solid heterogeneous reactions taking place at the interface between two phases. The model studies the reaction kinetics by taking into account the reactions at the interface, as well as the transport process within the product layer. The standard unreacted shrinking core model relies on the assumption of quasi-static diffusion that results in a steady-state. concentration profile of gas reactant in the product layer. By relaxing this assumption and resolving the entire problem, general solutions can be obtained for reaction kinetics, including the reaction front velocity and the conversion (volume fraction of reacted solid). The unreacted shrinking core model is shown to be accurate and in agreement with the generalized model for slow reaction (or fast diffusion), low concentration of gas reactant, and small solid size. Otherwise, a generalized kinetic model should be used. (C) 2012 American Institute of Physics.

TI Analysis of a Nuclear Accident: Fission and Activation Product Releases from the Fukushima Daiichi Nuclear Facility as Remote Indicators of Source Identification, Extent of Release, and State of Damaged Spent Nuclear Fuel SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID WATER-REACTOR ACCIDENTS; JAPAN; CORE; USA AB Researchers evaluated radionuclide measurements of 11 environmental samples taken from the Fukushima Daiichi nuclear facility and reported on the Tokyo Electric Power Co. Website following the 2011 tsunami-initiated catastrophe. This effort identified Units 1 and 3 as the major source of radioactive contamination to the surface soil near the facility. Radionuclide trends identified in the soils suggested that: (1) chemical volatility driven by temperature and reduction potential within the vented reactors' primary containment vessels dictated the extent of release of radiation; (2) all coolant had likely evaporated by the time of venting; and (3) physical migration through the fuel matrix and across the cladding wall were minimally effective at containing volatile species, suggesting damage to fuel bundles was extensive. Plutonium isotopic ratios and their distance from the source indicated that the damaged reactors were the major contributor of plutonium to surface soil at the source, decreasing rapidly with distance from the facility. Two independent evaluations estimated the fraction of the total plutonium inventory released to the environment relative to cesium from venting Units 1 and 3 to be similar to 0.002-0.004%. This study suggests significant volatile radionuclides within the spent fuel at the time of venting, but not as yet observed and reported within environmental samples, as potential analytes of concern for future environmental surveys around the site. The majority of the reactor inventories of isotopes of less volatile elements like Pu, Nb, and Sr were likely contained within the damaged reactors during venting.

TI Timing the Onset of Sulfate Reduction over Multiple Subsurface Acetate Amendments by Measurement and Modeling of Sulfur Isotope Fractionation SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID URANIUM BIOREMEDIATION; GROUNDWATER; TRANSPORT; AQUIFER; OXIDATION; SEDIMENTS; BACTERIA AB Stable isotope fractionations of sulfur are reported for three consecutive years of acetate-enabled uranium bioremediation at the US Department of Energy's Rifle Integrated Field Research Challenge (IFRC) site. The data show a previously undocumented decrease in the time between acetate addition and the onset of sulfate reducing conditions over subsequent amendments, from 20 days in the 2007 experiment to 4 days in the 2009 experiment. Increased sulfide concentrations were observed at the same time as delta S-34 of sulfate enrichment in the first year, but in subsequent years elevated sulfide was detected up to 15 days after increased delta S-34 of sulfate. A biogeochemical reactive transport model is developed which explicitly incorporates the stable isotopes of sulfur to simulate fractionation during the 2007 and 2008 amendments. A model based on an initially low, uniformly distributed population of sulfate reducing bacteria that grow and become spatially variable with time reproduces measured trends in solute concentration and delta S-34, capturing the change in onset of sulfate reduction in subsequent years. Our results demonstrate a previously unrecognized hysteretic effect in the spatial distribution of biomass growth during stimulated subsurface bioremediation.

This study aims to analyze the county-level water footprint for four biofiiel pathways in the United States, including bioethanol generated from corn grain, stover, wheat straw, and biodiesel from soybean. The county-level blue water footprint of ethanol from corn grain, stover, and wheat straw shows extremely wide variances with a national average of 31, 132, and 139 L of water per liter biofuel (L-w/L-bf), and standard deviation of 133, 323, and 297 L-w/L-bf, respectively. Soybean biodiesel production results in a blue water footprint of 313 L-w/L-bf on the national average with standard deviation of 894 L-w/L-bf. All biofuels show a greater green water footprint than the blue one. This work elucidates how diverse spatial resolutions affect biofuel water footprints, which can provide detailed insights into biofuels' implications on local water sustainability.

To understand the implications of such increased production on water resources and stream quality at regional and local scales, we have applied a watershed model for the Upper Mississippi River Basin, where most of the current and future crop/residue-based biofuel production is expected. The model simulates changes in water quality (soil erosion, nitrogen and phosphorus loadings in streams) and resources (soil-water content, evapotranspiration, and runoff) under projected biofuel production versus the 2006 baseline year and a business-as-usual scenario. The basin average results suggest that the projected feedstock production could change the rate of evapotranspiration in the UMRB by approximately +2%, soil-water content by about -2%, and discharge to streams by -5% from the baseline scenario. However, unlike the impacts on regional water availability, the projected feedstock production has a mixed effect on water quality, resulting in 12% and 45% increases in annual suspended sediment and total phosphorus loadings, respectively, but a 3% decrease in total nitrogen loading. These differences in water quantity and quality are statistically significant (p < 0.05). The basin responses are further analyzed at monthly time steps and finer spatial scales to evaluate underlying physical processes, which would be essential for future optimization of environmentally sustainable biofuel productions.

This paper presents a study of doping dependent O2 evolution electrocatalysis of Pr-doped CaMnO3 via in situ environmental transmission electron microscopy (ETEM) combined with ex situ cyclic voltammetry studies. ETEM studies of heterogeneous catalysis are a challenge, since the reactions in the H2O vapor phase cannot directly be observed. It is shown that the oxidation of silane by free oxygen to solid SiO2-x can be used to monitor catalytic oxygen evolution. Electron energy loss spectroscopy (EELS) as well as the in situ X-ray absorption study of near edge structures (XANES) in H2O vapor reveals that the Mn valence is decreased in the active state. Careful TEM analysis of samples measured by ex situ cyclic voltammetry and an in situ bias-controlled ETEM study allows us to distinguish between self-formation during oxygen evolution and corrosion at the Pr1-xCaxMnO3-H2O interface. Including density functional theory (DFT) calculations, trends in O2 evolution activity and defect chemistry in the active state can be correclated to doping induced changes of the electronic band structure in A-site doped manganites.

TI Separation of Americium from Curium by Oxidation and Ion Exchange SO ANALYTICAL CHEMISTRY LA English DT Article ID EXTRACTION CHROMATOGRAPHY; DHDECMP/XAD-4 RESIN; DHDECMP-HNO3 SYSTEM; ELEMENTS; FUEL AB Nuclear energy has the potential to be a clean alternative to fossil fuels, but in order for it to play a major role in the US, many questions about the back end of the fuel cycle must be addressed. One of these questions is the difficult separation of americium from curium. Here, we report the oxidation of Am in two systems, perchloric acid and nitric acid and the affect of changing the acid has on the oxidation. K-d values were observed and a direct separation factor was calculated and was seen to be as high as 20 for four metal(IV) pillared phosphate phosphonate inorganic organic hybrid ion exchange materials. These ion exchangers are characterized by very low selectivity for cations with low charge but extremely high uptake of ions of high charge.

A range of 3-14 800 ppmv was obtained with thin films of the MOP Cu-3(benzenetricarboxylate)(2) (Cu-BTC) deposited by an automated layer-by-layer method. Devices coated by a manual technique demonstrated sensitivity from 0.28 to 14 800 ppmv, the limit of our test system. This exceeds the sensitivity of many commercially available sensors. Cu-BTC layers were covalently bonded directly to the silicon oxide surface, allowing devices to be heated beyond 100 degrees C to desorb water adsorbed in the pores without decomposition, thereby regenerating the sensors. Sensor response as a function of coating thickness was evaluated, showing that the SAW sensor response is bounded by maximum and minimum layer thicknesses. Computer simulation of H2O uptake shows a multistep adsorption isotherm defined by initial adsorption at open Cu-sites, followed by pore-filling and finally full saturation. Modeling and experimental results are consistent. Calculated uptake values suggest an efficient adsorption of H2O by Cu-BTC. These results provide the first convincing evidence that MOP functionalization of compact sensing technologies such as SAW devices and microcantilevers can compete with state-of-the art devices.

Previous studies have shown that LSOA constituents are multifunctional compounds containing at least one aldehyde or ketone groups. In this study, we used the selectivity of the Girard's reagent T (GT) toward carbonyl compounds to examine the utility of reactive nano-DESI for the analysis of complex organic mixtures. In these experiments, 1-100 mu M GT solutions were used as the working solvents for reactive nano-DESI analysis. Abundant products from the single addition of GT to LSOA constituents were observed at GT concentrations in excess of 10 mu M. We found that LSOA dimeric and trimeric compounds react with GT through a simple addition reaction resulting in formation of the carbinolamine derivative. In contrast, reactions of GT with monomeric species result in the formation of both the carbinolamine and the hydrazone derivatives. In addition, several monomers did not react with GT on the time scale of our experiment. These molecules were characterized by relatively high values of the double bond equivalent and low oxygen content. Furthermore, because addition of a charged GT tag to a neutral molecule eliminates the discrimination against the low proton affinity compounds in the ionization process, reactive nano-DESI analysis enables quantification of individual compounds in the complex mixture. For example, we were able to estimate for the first time the amounts of dimers and trimers in the LSOA mixture. Specifically, we found that the most abundant LSOA dimer was detected at the similar to 0.5 pg level and the total amount of dimers and trimers in the analyzed sample was similar to 11 pg. Our results indicate that reactive nano-DESI is a valuable approach for examining the presence of specific functional groups and for the quantification of compounds possessing these groups in complex mixtures.

TI An observationally based evaluation of cloud ice water in CMIP3 and CMIP5 GCMs and contemporary reanalyses using contemporary satellite data SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article ID GENERAL-CIRCULATION MODEL; LARGE-SCALE MODELS; PHASE ARCTIC CLOUD; FRONTAL CLOUDS; SINGLE-COLUMN; GLOBAL PRECIPITATION; TROPICAL CONVECTION; STRATIFORM CLOUDS; RETRIEVAL METHODS; RESOLVING MODELS AB We perform an observationally based evaluation of the cloud ice water content (CIWC) and path (CIWP) of present-day GCMs, notably 20th century CMIP5 simulations, and compare these results to CMIP3 and two recent reanalyses. We use three different CloudSat + CALIPSO ice water products and two methods to remove the contribution from the convective core ice mass and/or precipitating cloud hydrometeors with variable sizes and falling speeds so that a robust observational estimate can be obtained for model evaluations. The results show that for annual mean CIWP, there are factors of 2-10 in the differences between observations and models for a majority of the GCMs and for a number of regions. However, there are a number of CMIP5 models, including CNRM-CM5, MRI, CCSM4 and CanESM2, as well as the UCLA CGCM, that perform well compared to our past evaluations. Systematic biases in CIWC vertical structure occur below the mid-troposphere where the models overestimate CIWC, with this bias arising mostly from the extratropics. The tropics are marked by model differences in the level of maximum CIWC (similar to 250-550 hPa). Based on a number of metrics, the ensemble behavior of CMIP5 has improved considerably relative to CMIP3, although neither the CMIP5 ensemble mean nor any individual model performs particularly well, and there are still a number of models that exhibit very large biases despite the availability of relevant observations. The implications of these results on model representations of the Earth radiation balance are discussed, along with caveats and uncertainties associated with the observational estimates, model and observation representations of the precipitating and cloudy ice components, relevant physical processes and parameterizations.

TI Reply to "Comment on 'Precision global measurements of London penetration depth in FeTe0.58Se0.42'" SO PHYSICAL REVIEW B LA English DT Editorial Material ID SUPERCONDUCTORS AB We reply to the Comment by Klein, Rodi` ere, and Marcenat [Phys. Rev. B 86, 066501 (2012)] on our paper [Phys. Rev. B 84, 174502 (2011)]. Our work was motivated by Klein et al. [Phys. Rev. B 82, 184506 (2010)]. In their paper, Klein et al. have attributed a factor of 5 difference in the value of the London penetration depth obtained from their tunnel diode resonator (TDR) measurements and calculated from the "field of first penetration" to the surface roughness, although they have not verified it experimentally. In our paper, we have studied the effects of deliberately introduced surface roughness and found that its effects are minor and cannot be responsible for the difference of such magnitude. Instead, we suggest that the value of the field of first penetration measured with Hall arrays cannot be used to extract a true lower critical field due to several reasons outlined in our Reply. We emphasize that the accuracy of the calibration procedure of the TDR technique has been carefully verified in several prior studies and our work on FeTe0.58Se0.42 further confirms it. We show that in their Comment, Klein et al. use wrong arguments of the universal behavior of the superfluid density in the gapless limit, because it is inapplicable for the multiband superconductors. We also discuss the applicability of the clean-limit. model and the influence of the disorder on the obtained results. C1 [Prozorov, R.] Ames Lab, Ames, IA 50011 USA.

TI Probing the bulk electronic states of Bi2Se3 using nuclear magnetic resonance SO PHYSICAL REVIEW B LA English DT Article ID TUNABLE TOPOLOGICAL INSULATOR; SOLID-STATE; TRANSPORT; CRYSTALS; SURFACE; BI2TE3; NMR AB We report a nuclear magnetic resonance (NMR) study of Bi2Se3 single crystals grown by three different methods. All the crystals show nine well-resolved peaks in their Bi-209 NMR spectra of the nuclear quadrupolar splitting, albeit with an intensity anomaly. Spectra at different crystal orientations confirm that all the peaks are purely from the nuclear quadrupolar effect, with no other hidden peaks. We identify the short nuclear transverse relaxation time (T-2) effect as the main cause of the intensity anomaly. We also show that the Bi-209 signal originates exclusively from bulk, while the contribution from the topological surface states is too weak to be detected by NMR. However, the bulk electronic structure in these single crystals is not the same, as identified by the NMR frequency shift and nuclear spin-lattice relaxation rate (1/T-1). The difference is caused by the different structural defect levels. We find that the frequency shift and 1/T-1 are smaller in samples with fewer defects and a lower carrier concentration. Also, the low-temperature power law of the temperature-dependent 1/T-1 (proportional to T-alpha) changes from the Korringa behavior alpha = 1 in a highly degenerate semiconductor (where the electrons obey Fermi statistics) to alpha < 1 in a less degenerate semiconductor (where the electrons obey Boltzmann statistics).

The new calculations improve on HPQCD's earlier work with NRQCD b-quarks by replacing AsqTad with HISQ valence quarks, by including a more chiral MILC fine ensemble in the analysis, and by employing better tuned quark masses and overall scale. We find f (B) = 0.191(9) GeV, f (Bs) = 0.228(10) GeV and f (Bs)/f (B) = 1.188(18). Combining the new value for f (Bs)/f (B) with a recent very precise determination of the B-s meson decay constant based on HISQ b-quarks, f (Bs) = 0.225(4) GeV, leads to f (B) = 0.189(4) GeV.

CA ATLAS Collaboration TI Search for tb Resonances in Proton-Proton Collisions at root s=7 TeV with the ATLAS Detector SO PHYSICAL REVIEW LETTERS LA English DT Article ID PARTON DISTRIBUTIONS AB This Letter presents a search for tb resonances in 1.04 fb(-1) of LHC proton-proton collision data collected by the ATLAS detector at a center-of-mass energy of 7 TeV. Events with a lepton, missing transverse momentum, and two jets are selected and the invariant mass of the corresponding final state is reconstructed. The search exploits the shape of the tb invariant mass distribution compared to the expected standard model backgrounds. The model of a right-handed W'(R) with standard model-like couplings is chosen as the benchmark model for this search. No statistically significant excess of events is observed in the data, and upper limits on the cross section times the branching ratio of W'(R) resonances at 95% C.L. lie in the range of 6.1-1.0 pb for W'(R) masses ranging from 0.5 to 2.0 TeV. These limits are translated into a lower bound on the allowed right-handed W'(R) mass, giving mW'(R) > 1.13 TeV at 95% C.L.

Taillefer, Louis TI Universal Heat Conduction in the Iron Arsenide Superconductor KFe2As2: Evidence of a d-Wave State SO PHYSICAL REVIEW LETTERS LA English DT Article ID QUASI-PARTICLE TRANSPORT; THERMAL-CONDUCTIVITY; VORTEX STATE; YBA2CU3O6.9 AB The thermal conductivity kappa of the iron arsenide superconductor KFe2As2 was measured down to 50 mK for a heat current parallel and perpendicular to the tetragonal c axis. A residual linear term at T -> 0, kappa(0)/T is observed for both current directions, confirming the presence of nodes in the superconducting gap. Our value of kappa(0)/T in the plane is equal to that reported by Dong et al. [Phys. Rev. Lett. 104, 087005 (2010)] for a sample whose residual resistivity rho(0) was 10 times larger. This independence of kappa(0)/T on impurity scattering is the signature of universal heat transport, a property of superconducting states with symmetry-imposed line nodes. This argues against an s-wave state with accidental nodes. It favors instead a d-wave state, an assignment consistent with five additional properties: the magnitude of the critical scattering rate Gamma(c) for suppressing T-c to zero; the magnitude of kappa(0)/T, and its dependence on current direction and on magnetic field; the temperature dependence of kappa(T).

The measured pairwise spin correlations of both lattices can be reproduced by models based solely on nearest-neighbor correlations. The kagome array has qualitatively different magnetostatics but identical lattice topology to previously studied artificial spin ice systems composed of in-plane moments. The two systems show striking similarities in the development of moment pair correlations, demonstrating a universality in artificial spin ice behavior independent of specific realization in a particular material system.

TI Interpreting the widespread nonlinear force spectra of intermolecular bonds SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE single molecule mechanics; multivalency; nonequilibrium dynamics; free energy ID MOLECULE PULLING EXPERIMENTS; ENERGY LANDSCAPES; DYNAMIC STRENGTH; SPECTROSCOPY; SINGLE; ADHESION; MICROSCOPY; RUPTURE; RATES; RECOGNITION AB Single molecule force spectroscopy probes the strength, lifetime, and energetic details of intermolecular interactions in a simple experiment. A growing number of these studies have reported distinctly nonlinear trends in rupture force with loading rate that are typically explained in conventional models by invoking complex escape pathways. Recent analyses suggested that these trends should be expected even for simple barriers based on the basic assumptions of bond rupture dynamics and thus may represent the norm rather than the exception. Here we explore how these nonlinear trends reflect the two fundamental regimes of bond rupture: (i) a near-equilibrium regime, produced either by bond reforming in the case of a single bond or by asynchronized rupture of multiple individual bonds, and (ii) a kinetic regime produced by fast, non-equilibrium bond rupture. We analyze both single- and multi-bonded cases, describe the full evolution of the system as it transitions between near-and far-from-equilibrium loading regimes, and show that both interpretations produce essentially identical force spectra. Data from 10 different molecular systems show that this model provides a comprehensive description of force spectra for a diverse suite of bonds over experimentally relevant loading rates, removes the inconsistencies of previous interpretations of transition state distances, and gives ready access to both kinetic and thermodynamic information about the interaction. These results imply that single-molecule binding free energies for a vast number of bonds have already been measured.

The target has been utilized for photoproduction measurements with polarized tagged photons of both longitudinal and circular polarization. Protons in TEMPO-doped butanol were dynamically polarized to approximately 90% outside the spectrometer at 5 T and 200-300 mK. Photoproduction data were acquired with the target inside the spectrometer at a frozen-spin temperature of approximately 30 mK with the polarization maintained by a thin, superconducting coil installed inside the target cryostat. A 0.56 T solenoid was used for longitudinal target polarization and a 0.50 T dipole for transverse polarization. Spin-lattice relaxation times as high as 4000 h were observed.

TI Electronic neutron sources for compensated porosity well logging SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Neutron generator; Oil well logging; MCNP; Porosity AB The viability of replacing Americium-Beryllium (Am-Be) radiological neutron sources in compensated porosity nuclear well logging tools with D-T or D-D accelerator-driven neutron sources is explored. The analysis consisted of developing a model for a typical well-logging borehole configuration and computing the helium-3 detector response to varying formation porosities using three different neutron sources (Am-Be, D-D, and D-T). The results indicate that, when normalized to the same source intensity, the use of a D-D neutron source has greater sensitivity for measuring the formation porosity than either an Am-Be or D-T source. The results of the study provide operational requirements that enable compensated porosity well logging with a compact, low power D-D neutron generator, which the current state-of-the-art indicates is technically achievable.

TI Conventional and Stuffed Bergman-Type Phases in the Na-Au-T (T=Ga, Ge, Sn) Systems: Syntheses, Structures, Coloring of Cluster Centers, and Fermi Sphere-Brillouin Zone Interactions SO INORGANIC CHEMISTRY LA English DT Article ID ICOSAHEDRAL QUASI-CRYSTAL; INTERMETALLIC COMPOUND; BUILDING-BLOCKS; GAS-PHASE; X-RAY; APPROXIMANT; AU-20; DIFFRACTION; GALLIUM AB Bergman-type phases in the Na-Au-T (T = Ga, Ge, and Sn) systems were synthesized by solid-state means and structurally characterized by single-crystal X-ray diffraction studies. Two structurally related (1/1) Bergman phases were found in the Na-Au-Ga system: (a) a conventional Bergman-type (CB) structure, Na26AuxGa54-x, which features empty innermost icosahedra, as refined with x = 18.1 (3), Im (3) over bar, a = 14.512(2) angstrom, and Z = 2; (b) a stuffed Bergman-type (SB) structure, Na26AuyGa55-y, which contains Ga-centered innermost icosahedra, as refined with y = 36.0 (1), Im (3) over bar, a = 14.597(2) angstrom, and Z = 2. Although these two subtypes have considerable phase widths along with respective tie lines at Na approximate to 32.5 and 32.1 atom %, they do not merge into a continuous solid solution. Rather, a quasicrystalline phase close to the Au-poor CB phase and an orthorhombic derivative near the Au-rich SB phase lie between them. In contrast, only Au-rich SB phases exist in the Ge and Sn systems, in which the innermost icosahedra are centered by Au rather than Ge or Sn. These were refined for Na26Au40.93(5)Ge14.07(5) (Im (3) over bar, a = 14.581(2) angstrom, and Z = 2) and Na26Au39.83(6)Sn15.17(6) (Im (3) over bar, a = 15.009(2) angstrom, and Z = 2), respectively. Occupations of the centers of Bergman clusters are rare. Such centering and coloring correlate with the sizes of the neighboring icosahedra, the size ratios between electropositive and electronegative components, and the values of the average valence electron count per atom (e/a). Theoretical calculations revealed that all of these phases are Hume-Rothery phases, with evident pseudogaps in the density of states curves that arise from the interactions between Fermi surface and Brillouin zone boundaries corresponding to a strong diffraction intensity.

Data support the periodic progression to primarily bidentate sulfate coordination about An(IV) centers when moving heavier in the actinides. This observation is attributed to the increase in Lewis acidity of the tetravalent actinides across the series, a consequence of the filling of the 5f orbitals and the actinide contraction. Though the changes in the chemical formation energies of the An(IV) complexes between Th and Pu are small, it is these small energetic differences that are critical to understanding how to effect more efficient and effective chemical separations among isovalent metal ions.

The results show that the uranyl ion forms three strong successive mononuclear complexes with acetate. The complexes, both enthalpically and entropically stabilized, are significantly more stable in DMSO than in water. This feature can be ascribed to the weak solvation of acetate in DMSO. The thermodynamic parameters for the formation of the uranium(VI) complexes with acetate in DMSO are compared with those with ethylenediamine in the same solvent. The difference between the two ligand systems reveals that, for the complexation reactions involving charge neutralization, the reorganization of the solvent gives a very important contribution to the overall complexation energetics. The coordination mode of acetate in the uranyl complexes and the changes of the solvation sphere of UO22+ upon complexation were investigated by FT-IR spectroscopy in DMSO and in acetonitrile/DMSO mixtures. In addition, DFT calculations were performed to provide an accurate description of the complexation at the molecular level. The experimental and calculated results suggest that acetate is solely bidentate to UO22+ in the 1:1 and 1:3 complexes but mono- and bidentate in the 1:2 complexes. The DFT calculations also indicate that the medium effects must always be taken into account in order to gain accurate information on the complex formation in solution. In fact, the relative stability of the reaction products changes markedly when the DFT calculations are carried out in vacuum or in DMSO solution.

TI MULTIWAVELENGTH OBSERVATIONS OF THE AGN 1ES 0414+009 WITH VERITAS, FERMI-LAT, SWIFT-XRT, AND MDM SO ASTROPHYSICAL JOURNAL LA English DT Article DE BL Lacertae objects: individual (1ES 0414+009, ERJ0416+011); gamma rays: galaxies ID BL LACERTAE OBJECT; GAMMA-RAY ASTRONOMY; TELESCOPE; EMISSION; SEARCH; DISCOVERY; BLAZARS; SAMPLE; STARS AB We present observations of the BL Lac object 1ES 0414+009 in the >200 GeV gamma-ray band by the VERITAS array of Cherenkov telescopes. 1ES 0414+009 was observed by VERITAS between 2008 January and 2011 February, resulting in 56.2 hr of good quality pointed observations. These observations resulted in a detection of 822 events from the source corresponding to a statistical significance of 6.4 standard deviations (6.4 sigma) above the background. The source flux, showing no evidence for variability, is measured as (5.2 +/- 1.1(stat) +/- 2.6(sys)) x 10(-12) photons cm(-2) s(-1) above 200 GeV, equivalent to approximately 2% of the Crab Nebula flux above this energy. The differential photon spectrum from 230 GeV to 850 GeV is well fit by a power law with a photon index of Gamma = 3.4 +/- 0.5(stat) +/- 0.3(sys) and a flux normalization of (1.6 +/- 0.3(stat) +/- 0.8(sys)) x 10(-11) photons cm(-2) s(-1) at 300 GeV. We also present multiwavelength results taken in the optical (MDM), x-ray (Swift-XRT), and GeV (Fermi-LAT) bands and use these results to construct a broadband spectral energy distribution (SED). Modeling of this SED indicates that homogenous one-zone leptonic scenarios are not adequate to describe emission from the system, with a lepto-hadronic model providing a better fit to the data.

Multi-dimensional modeling of core-collapse supernovae has been undertaken since SN1987A, and both simulations and observations suggest/showthat Rayleigh-Taylor (RT) instabilities during the explosion is a main driver of the formation of structure in the remnants. We present a case study of structure formation in three dimensions in a 15 M-circle dot supernova for different parameters. We investigate the effect of moderate asymmetries and different resolutions of the formation and morphology of the RT unstable region, and take first steps toward determining typical physical quantities (size, composition) of arising clumps. We find that in this progenitor the major RT unstable region develops at the He/OC interface for all cases considered. The RT instabilities result in clumps that are overdense by one to two orders of magnitude with respect to the ambient gas, have size scales on the level of a few percent of the remnant diameter, and are not diffused after the first similar to 30 yr of the remnant evolution, in the absence of a surrounding medium.

The sample consists of almost 200 spectroscopically or photometrically confirmed SNe Ia at redshifts below 0.25. The sample is split into two groups depending on the morphology of the host galaxy. We fit light curves using both MLCS2k2 and SALT2, and determine color (A(V), c) and light-curve shape (Delta, x(1)) parameters for each SN Ia, as well as its residual in the Hubble diagram. We then correlate these parameters with both the physical and the normalized distances to the center of the host galaxy and look for trends in the mean values and scatters of these parameters with increasing distance. The most significant (at the 4 sigma level) finding is that the average fitted A(V) from MLCS2k2 and c from SALT2 decrease with the projected distance for SNe Ia in spiral galaxies. We also find indications that supernovae (SNe) in elliptical galaxies tend to have narrower light curves if they explode at larger distances, although this may be due to selection effects in our sample. We do not find strong correlations between the residuals of the distance moduli with respect to the Hubble flow and the galactocentric distances, which indicates a limited correlation between SN magnitudes after standardization and local host metallicity.

The computational model represents a collisionless, homogeneous, magnetized plasma on which an initial spectrum of relatively long wavelength whistler fluctuations is imposed. The simulations represent a range of initial fluctuation amplitudes and follow the temporal evolution of the system as it decays into a broadband, anisotropic, turbulent spectrum at shorter wavelengths via a forward cascade. The resulting 3D turbulence is similar in many ways to whistler turbulence from previous two-dimensional (2D) PIC simulations, although the anisotropies in 3D are stronger than in comparable 2D runs. The most important difference is that reduced magnetic fluctuation spectra from the 3D simulations show a clear break in the perpendicular wavenumber (k(perpendicular to)) spectra. Spectra at small k(perpendicular to) are relatively steep, but spectra at larger k(perpendicular to) are even steeper, similar in character to magnetic spectra at electron scales recently measured in the solar wind.

Our choice of photometric and spectroscopic properties was motivated by SN 2005E (Perets et al.). To our surprise, as in the case of SN 2005E, all four members of this group are also clearly offset from the bulk of their host galaxy. Given the well-sampled early-and late-time light curves, we derive ejecta masses in the range of 0.4-0.7 M-circle dot. Spectroscopically, we find that there may be a diversity in the photospheric phase, but the commonality is in the unusual nebular spectra. Our extensive follow-up observations rule out standard thermonuclear and standard core-collapse explosions for this class of "calcium-rich gap" transients. If the progenitor is a white dwarf, we are likely seeing a detonation of the white dwarf core and perhaps even shock-front interaction with a previously ejected nova shell. If the progenitor is a massive star, a nonstandard channel specific to a low-metallicity environment needs to be invoked (e. g., ejecta fallback leading to black hole formation). Detection (or the lack thereof) of a faint underlying host (dwarf galaxy and cluster) will provide a crucial and decisive diagnostic to choose between these alternatives.

BRIGHT UV STARS IN THE BULGE OF M31 SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: evolution; galaxies: individual (M31); galaxies: stellar content; stars: evolution; stars: horizontal-branch ID EARLY-TYPE GALAXIES; GALACTIC GLOBULAR-CLUSTERS; HORIZONTAL-BRANCH STARS; SUBDWARF-B-STARS; ELLIPTIC GALAXIES; STELLAR POPULATIONS; FAR-ULTRAVIOLET; GIANT BRANCH; SURFACE PHOTOMETRY; LINE-STRENGTHS AB As part of the Panchromatic Hubble Andromeda Treasury multi-cycle program, we observed a 12' x 6.'5 area of the bulge of M31 with theWFC3/UVIS filters F275W and F336W. From these data we have assembled a sample of similar to 4000 UV-bright, old stars, vastly larger than previously available. We use updated Padova stellar evolutionary tracks to classify these hot stars into three classes: Post-AGB stars (P-AGB), Post-Early AGB (PE-AGB) stars, and AGB-manque stars. P-AGB stars are the end result of the asymptotic giant branch (AGB) phase and are expected in a wide range of stellar populations, whereas PE-AGB and AGB-manque (together referred to as the hot post-horizontal branch; HP-HB) stars are the result of insufficient envelope masses to allow a full AGB phase, and are expected to be particularly prominent at high helium or alpha abundances when the mass loss on the red giant branch is high. Our data support previous claims that most UV-bright sources in the bulge are likely hot (extreme) horizontal branch (EHB) stars and their progeny. We construct the first radial profiles of these stellar populations and show that they are highly centrally concentrated, even more so than the integrated UV or optical light. However, we find that this UV-bright population does not dominate the total UV luminosity at any radius, as we are detecting only the progeny of the EHB stars that are the likely source of the UV excess. We calculate that only a few percent of main-sequence stars in the central bulge can have gone through the HP-HB phase and that this percentage decreases strongly with distance from the center. We also find that the surface density of hot UV-bright stars has the same radial variation as that of low-mass X-ray binaries. We discuss age, metallicity, and abundance variations as possible explanations for the observed radial variation in the UV-bright population. C1 [Rosenfield, Philip; Johnson, L.

The electrodeposited silicon films were characterized for their composition, morphology and structural characteristics using glancing angle X-ray diffraction (GAXRD), scanning electron microscopy (SEM), and Raman spectroscopy. GAXRD and Raman analyses clearly confirm the amorphous state of the deposited silicon film. The deposited films were tested for possible application as anodes for Li-ion battery. The results indicate that this binder free amorphous silicon anode exhibits a reversible capacity of similar to 1300 mAh g(-1) with a columbic efficiency of > 99.5% up to 100 cycles. Impedance measurements at the end of each charge cycle show a non-variable charge transfer resistance which contributes to the excellent cyclability over 100 cycles observed for the films. This approach of developing thin amorphous silicon films directly on copper eliminates the use of binders and conducting additives, rendering the process simple, facile and easily amenable for large scale manufacturing.

A distinct shoulder feature on the absorption edge reflecting the unoccupied oxygen 2p states is evident in the intrinsic thin films, which diminishes upon Fe doping, while a pre-edge absorption feature (reflecting the O 2p-Fe 3d acceptor state) evolves with the same. Our findings demonstrate the reduction in the intrinsic holes as a result of charge-transfer hole doping. All the thin films display room-temperature ferromagnetism, and the saturation magnetization is found to increase from ca. 0.70 -> 4.34 emu/cm(3) on 7 at. % Fe doping.

TI Electron spin resonance shift and linewidth broadening of nitrogen-vacancy centers in diamond as a function of electron irradiation dose SO APPLIED PHYSICS LETTERS LA English DT Article ID PHOTOLUMINESCENCE MICROSCOPY; RESOLUTION AB A high-nitrogen-concentration diamond sample was subjected to 200-keV electron irradiation using a transmission electron microscope. The optical and spin-resonance properties of the nitrogen-vacancy (NV) color centers were investigated as a function of the irradiation dose up to 6.4 x 10(21) e(-)/cm(2). The microwave transition frequency of the NV- center was found to shift by up to 0.6% (17.1 MHz) and the linewidth broadened with increasing electron-irradiation dose. Unexpectedly, the measured magnetic sensitivity is best at the lowest irradiation dose, even though the NV concentration increases monotonically with increasing dose. This is in large part due to a sharp reduction in optically detected spin contrast at higher doses. (C) 2012 American Institute of Physics.

Within this diagram, it is expected that the activation energy of electron traps of the same microscopic nature should decrease with the increase of nitrogen concentration. The identification of electron traps in GaNAs within the proposed diagram allows to interpret the broad emission at similar to 0.9 eV as the donor trap-valence band and the donor acceptor pair recombination involving of these traps.

Despite considerable development of nanocup fabrication processes, simultaneously achieving accurate control over the placement, orientation, and geometry of nanocups has remained a significant challenge. Here we present a technique for fabricating large, periodically ordered arrays of uniformly oriented three-dimensional gold nanocups for manipulating light at subwavelength scales. Nanoimprint lithography, soft lithography, and shadow evaporation were used to fabricate nanocups onto the tips of polydimethylsiloxane nanopillars with precise control over the shapes and optical properties of asymmetric nanocups.

TI A remotely interrogated all-optical Rb-87 magnetometer SO APPLIED PHYSICS LETTERS LA English DT Article AB Atomic magnetometry was performed at Earth's magnetic field over a free-space distance of ten meters. Two laser beams aimed at a distant alkali-vapor cell excited and detected the Rb-87 magnetic resonance, allowing the magnetic field within the cell to be interrogated remotely. Operated as a driven oscillator, the magnetometer measured the geomagnetic field with less than or similar to 3.5 pT precision in a similar to 2 s data acquisition; this precision was likely limited by ambient field fluctuations. The sensor was also operated in self-oscillating mode with a 5.3 pT root Hz noise floor. Further optimization will yield a high-bandwidth, fully remote magnetometer with sub-pT sensitivity.

With the meticulous design of the ELC resonator, we can achieve a negative index metamaterial through mode hybridization by overlapping the first electric resonance mode and the second magnetic resonance mode.

Upon increasing demand on the device applications, graphene is viewed as a prototypical system for engineering v(F). Indeed, several efforts have succeeded in modifying v(F) by varying charge carrier concentration, n. Here we present a powerful but simple new way to engineer v(F) while holding n constant. We find that when the environment embedding graphene is modified, the v(F) of graphene is (i) inversely proportional to its dielectric constant, reaching v(F) similar to 2.5 x 10(6) m/s, the highest value for graphene on any substrate studied so far and (ii) clearly distinguished from an ordinary Fermi liquid. The method demonstrated here provides a new route toward Fermi velocity engineering in a variety of two-dimensional electron systems including topological insulators.

We restrict ourselves to self-gravitating bound objects and base our results on halo mass functions derived from N-body simulations. The mass and redshift distribution of the largest objects in the universe are potentially interesting tests of Lambda CDM, probing the initial conditions, non-Gaussianity, and the behavior of gravity on large scales. We discuss A2163 and A370 as candidates for the most massive cluster in the universe, although uncertainties in their masses preclude definitive comparisons with theory. We find that the three most massive clusters in the South Pole Telescope (SPT) 178 and 2500 deg(2) catalogs match predictions. Since the mass function evolves steeply with redshift, we also investigate the most unlikely clusters in the universe. We find that SPT-CL J2106-5844 is 2 sigma and XMMU J2235.3-2557 is 3 sigma inconsistent with Lambda CDM, considering their respective redshifts and survey sizes. Our findings motivate further observations of the highest mass end of the mass function, particularly at z > 1, where a number of anomalously massive clusters have been discovered. Future surveys will explore larger volumes, and both the most massive object and the most unlikely object in the universe may be identified within the next decade.

TI Lattice dynamics reveals a local symmetry breaking in the emergent dipole phase of PbTe SO PHYSICAL REVIEW B LA English DT Article ID LEAD-TELLURIDE; ENERGY; SCATTERING AB Local symmetry breaking in complex materials is emerging as an important contributor to materials properties but is inherently difficult to study. Here we follow up an earlier structural observation of such a local symmetry broken phase in the technologically important compound PbTe with a study of the lattice dynamics using inelastic neutron scattering (INS). We show that the lattice dynamics are responsive to the local symmetry broken phase, giving key insights in the behavior of PbTe, but also revealing INS as a powerful tool for studying local structure. The new result is the observation of the unexpected appearance upon warming of a new zone center phonon branch in PbTe. In a harmonic solid the number of phonon branches is strictly determined by the contents and symmetry of the unit cell. The appearance of the new mode indicates a crossover to a dynamic lower symmetry structure with increasing temperature. No structural transition is seen crystallographically, but the appearance of the new mode in inelastic neutron scattering coincides with the observation of local Pb off-centering dipoles observed in the local structure. The observation resembles relaxor ferroelectricity, but since there are no inhomogeneous dopants in pure PbTe this anomalous behavior is an intrinsic response of the system. We call such an appearance of dipoles out of a nondipolar ground-state "emphanisis" meaning the appearance out of nothing. It cannot be explained within the framework of conventional phase transition theories such as soft-mode theory and challenges our basic understanding of the physics of materials.

TI Magnetic dead layer at the interface between a Co film and the topological insulator Bi2Se3 SO PHYSICAL REVIEW B LA English DT Article ID HGTE QUANTUM-WELLS; PHASE-TRANSITION; FE FILMS; SURFACE; COBALT AB Co films were grown on top of a topological insulator Bi2Se3(111) substrate and studied using magneto-optic Kerr effect (MOKE) and x-ray magnetic circular dichroism (XMCD). Both MOKE and XMCD results show that there exists a similar to 1.2-nm-thick magnetic dead layer of the Co film; i.e., an similar to 1.2-nm Co film at the Co/Bi2Se3(111) interface loses its ferromagnetic order. The Co ferromagnetic order can be completely resumed by inserting a 3-nm Ag layer between the Co and Bi2Se3, indicating that the magnetic dead layer is due to the Co/Bi2Se3 interfacial mixing which is supported by the Co L-edge spectroscopy results.

TI Anisotropic conductivity of uncharged domain walls in BiFeO3 SO PHYSICAL REVIEW B LA English DT Article ID THIN-FILMS; DEFORMATION; SEMICONDUCTORS; CONDUCTANCE; SCATTERING; PHYSICS AB Experimental observations suggest that nominally uncharged, as-grown domain walls in ferroelectrics can be conductive, yet comprehensive theoretical models to explain this behavior are lacking. Here, Landau-Ginzburg-Devonshire theory is used to evolve an analytical treatment of the anisotropic carrier accumulation by nominally uncharged domain walls in multiferroic BiFeO3. Strong angular dependence of the carrier accumulation by 180. domain walls originates from local band bending via angle-dependent electrostriction and flexoelectric coupling mechanisms. Theoretical results are in qualitative agreement with experimental data and provide a counterpart that is consistent with recent first-principles calculations. These studies suggest that a significantly more diverse range of domain wall structures could possess novel electronic properties than previously believed. Similarly, emergent electronic behaviors at ferroic walls are typically underpinned by multiple mechanisms, necessitating first-principles studies of corresponding coupling parameters.

TI Evolution of the spin-state transition with doping in La1-xSrxCoO3 SO PHYSICAL REVIEW B LA English DT Article AB The thermally induced spin-state transition of Co3+ ions in the cobaltite LaCoO3, found at temperatures in the range 40 to 120 K, has been the subject of extensive experimental and theoretical investigation. Much less is known about what happens to the spin-state transition in hole-doped La1-xSrxCoO3 (LSCO). The present La-139 NMR experiments show that spin-state transitions persist in nanoscale hole-poor regions of the inhomogeneous doped material. In fact, thermally induced spin-state transitions remain important for doping levels close to the metal-insulator critical concentration of x(C) = 0.17. This finding suggests that the unusual glassy behavior seen in doped LSCO for x < 0.18 results from the interplay of spin-state transitions in hole-poor regions and ferromagnetism in hole-rich regions.

Rev. B 59, 2267 (1999); Giannozzi et al., J. Phys.: Condens. Matter 21, 395502 (2009)] has the limitation that it only allows transport directions along lattice vectors perpendicular to the basal plane formed by two other lattice vectors. We generalize the algorithm to low-symmetry, nonorthogonal lattices thus allowing solution to problems in which the transport direction is not along any lattice vectors. As an application, we calculate the transmission and reflection coefficients, and determine interface resistivity of various grain boundaries in crystalline copper.

CA PHENIX Collaboration TI Nuclear-modification factor for open-heavy-flavor production at forward rapidity in Cu plus Cu collisions at root s(NN)=200 GeV SO PHYSICAL REVIEW C LA English DT Article ID QUARK-GLUON PLASMA; ION COLLISIONS; QCD MATTER; LHC AB Background: Heavy-flavor production in p + p collisions is a good test of perturbative-quantum-chromodynamics (pQCD) calculations. Modification of heavy-flavor production in heavy-ion collisions relative to binary-collision scaling from p + p results, quantified with the nuclear-modification factor (R-AA), provides information on both cold-and hot-nuclear-matter effects. Midrapidity heavy-flavor R-AA measurements at the Relativistic Heavy Ion Collider have challenged parton-energy-loss models and resulted in upper limits on the viscosity-entropy ratio that are near the quantum lower bound. Such measurements have not been made in the forward-rapidity region. Purpose: Determine transverse-momentum (p(T)) spectra and the corresponding R-AA for muons from heavy-flavor meson decay in p + p and Cu + Cu collisions at root s(NN) = 200 GeV and y = 1.65. Method: Results are obtained using the semileptonic decay of heavy-flavor mesons into negative muons. The PHENIX muon-arm spectrometers measure the p(T) spectra of inclusive muon candidates. Backgrounds, primarily due to light hadrons, are determined with a Monte Carlo calculation using a set of input hadron distributions tuned to match measured-hadron distributions in the same detector and statistically subtracted. Results: The charm-production cross section in p + p collisions at root s = 200 GeV, integrated over p(T) and in the rapidity range 1.4 < y < 1.9, is found to be d(sigma e (e) over bar)/dy = 0.139 +/- 0.029 (stat)(-0.058)(+0.051) (syst) mb. This result is consistent with a perturbative fixed-order-plus-next-to-leading-log calculation within scale uncertainties and is also consistent with expectations based on the corresponding midrapidity charm-production cross section measured by PHENIX. The R-AA for heavy-flavor muons in Cu + Cu collisions is measured in three centrality bins for 1 < p(T) < 4 GeV/c. Suppression relative to binary-collision scaling (R-AA < 1) increases with centrality. Conclusions: Within experimental and theoretical uncertainties, the measured charm yield in p + p collisions is consistent with state-of-the-art pQCD calculations. Suppression in central Cu + Cu collisions suggests the presence of significant cold-nuclear-matter effects and final-state energy loss. C1 [Deaton, M. B.; Isenhower, D.; Isenhower, L.; Omiwade, O.

CA CDF Collaboration TI Search for the standard model Higgs boson produced in association with a W-+/- boson with 7.5 fb(-1) integrated luminosity at CDF SO PHYSICAL REVIEW D LA English DT Article ID ELECTROMAGNETIC CALORIMETER; MASSLESS PARTICLES; BROKEN SYMMETRIES; ROOT-S=7 TEV; UPGRADE; DETECTOR; COLLISIONS AB We present a search for the standard model Higgs boson produced in association with a W-+/- boson. This search uses data corresponding to an integrated luminosity of 7.5 fb(-1) collected by the CDF detector at the Tevatron. We select WH -> lvb (b) over bar candidate events with two jets, large missing transverse energy, and exactly one charged lepton. We further require that at least one jet be identified to originate from a bottom quark. Discrimination between the signal and the large background is achieved through the use of a Bayesian artificial neural network. The number of tagged events and their distributions are consistent with the standard model expectations. We observe no evidence for a Higgs boson signal and set 95% C.L. upper limits on the WH production cross section times the branching ratio to decay to b (b) over bar pairs, sigma(p (p) over bar -> (WH)-H-+/-) x B(H -> b (b) over bar), relative to the rate predicted by the standard model. For the Higgs boson mass range of 100 to 150 GeV/c(2) we set observed (expected) upper limits from 1.34 (1.83) to 38.8 (23.4). For 115 GeV/c(2) the upper limit is 3.64 (2.78). The combination of the present search with an independent analysis that selects events with three jets yields more stringent limits ranging from 1.12 (1.79) to 34.4 (21.6) in the same mass range. For 115 and 125 GeV/c(2) the upper limits are 2.65 (2.60) and 4.36 (3.69), respectively.

CA D0 Collaboration TI Search for Higgs boson production in oppositely charged dilepton and missing energy events in p(p)over-bar collisions at root s=1.96 TeV SO PHYSICAL REVIEW D LA English DT Article ID STANDARD MODEL; LHC; SPECTRUM AB We present a search for the standard model Higgs boson using events with two oppositely charged leptons and large missing transverse energy as expected in H -> WW decays. The events are selected from data corresponding to 8.6 fb(-1) of integrated luminosity in p (p) over bar collisions at root s = 1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. No significant excess above the standard model background expectation in the Higgs boson mass range this search is sensitive to is observed, and upper limits on the Higgs boson production cross section are derived.

Hooper, Dan TI Implications of a 130 GeV gamma-ray line for dark matter SO PHYSICAL REVIEW D LA English DT Article ID NEUTRALINO ANNIHILATION; ATLAS DETECTOR; SEARCH AB Recent reports of a gamma-ray line feature at similar to 130 GeV in data from the Fermi Gamma-Ray Space Telescope have generated a great deal of interest in models in which dark matter particles annihilate with a sizable cross section to final states including photons. In this paper, we take a model-independent approach and discuss a number of possibilities for dark matter candidates which could potentially generate such a feature. While we identify several scenarios which could lead to such a gamma-ray line, these models are each fairly constrained. In particular, viable models require large couplings (g greater than or similar to 1-3) and additional charged particles with masses in the range of approximately similar to 130-200 GeV. Furthermore, lower energy gamma-ray constraints from the Galactic center force us to consider scenarios in which the dark matter annihilates in the early Universe through velocity-suppressed processes or to final states which yield relatively few gamma-rays (such as e(+)e(-), mu(+)mu(-), or nu(nu) over bar). An exception to these conclusions can be found in models in which the dark matter annihilates to heavy intermediate states which decay to photons to generate a linelike gamma-ray spectrum.

A two-pole ansatz for the quark spectral function is used to determine the bare quark mass and the momentum dependence of excitation spectra on large lattices of size up to 128(3) x 16. The dependence of the quark correlator on these parameters as well as the finite volume dependence of the excitation energies are analyzed in detail in order to examine the reliability of our analysis. Our results suggest the existence of quasiparticle peaks in the quark spectrum. We furthermore find evidence that the dispersion relation of the plasmino mode has a minimum at nonzero momentum even in the nonperturbative region near T-c. We also elaborate on the enhancement of the quark correlator near the chiral limit which is observed at T = 1: 5T(c) on about half of the gauge configurations. We attribute this to the presence of near zero-modes of the fermion matrix that are associated with nontrivial topology of the gauge configurations.

TI Distance Walked and Run as Improved Metrics over Time-Based Energy Estimation in Epidemiological Studies and Prevention; Evidence from Medication Use SO PLOS ONE LA English DT Article ID VIGOROUS PHYSICAL-ACTIVITY; SELF-REPORT MEASURES; CARDIOVASCULAR RISK-FACTORS; CORONARY-HEART-DISEASE; ALL-CAUSE MORTALITY; OF-SPORTS-MEDICINE; 7-YEAR FOLLOW-UP; WEIGHT-GAIN; CARDIORESPIRATORY FITNESS; WALKING DISTANCE AB Purpose: The guideline physical activity levels are prescribed in terms of time, frequency, and intensity (e.g., 30 minutes brisk walking, five days a week or its energy equivalence) and assume that different activities may be combined to meet targeted goals (exchangeability premise). Habitual runners and walkers may quantify exercise in terms of distance (km/day), and for them, the relationship between activity dose and health benefits may be better assessed in terms of distance rather than time. Analyses were therefore performed to test: 1) whether time-based or distance-based estimates of energy expenditure provide the best metric for relating running and walking to hypertensive, high cholesterol, and diabetes medication use (conditions known to be diminished by exercise), and 2) the exchangeability premise. Methods: Logistic regression analyses of medication use (dependent variable) vs. metabolic equivalent hours per day (METhr/d) of running, walking and other exercise (independent variables) using cross-sectional data from the National Runners' (17,201 male, 16,173 female) and Walkers' Health Studies (3,434 male, 12,384 female). Results: Estimated METhr/d of running and walking activity were 38% and 31% greater, respectively, when calculated from self-reported time than distance in men, and 43% and 37% greater in women, respectively. Percent reductions in the odds for hypertension and high cholesterol medication use per METhr/d run or per METhr/d walked were >= 2-fold greater when estimated from reported distance (km/wk) than from time (hr/wk). The per METhr/d odds reduction was significantly greater for the distance-than the time-based estimate for hypertension (runners: P < 10(-5) for males and P = 0.003 for females; walkers: P = 0.03 for males and P < 10(-4) for females), high cholesterol medication use in runners (P < 10(-4) for males and P = 0.02 for females) and male walkers (P = 0.01 for males and P = 0.08 for females) and for diabetes medication use in male runners (P < 10(-3)). Conclusions: Although causality between greater exercise and lower prevalence of hypertension, high cholesterol and diabetes cannot be inferred from these cross-sectional data, the results do suggest that distance-based estimates of METhr/d run or walked provide superior metrics for epidemiological analyses to their traditional time-based estimates.

First, grouping the temporal data provides a richer, more robust representation of the underlying processes that are co-regulated. The net result is a significant dimensional reduction of the genome-wide array data into a smaller set of vocabularies for bioinformatics analysis. Second, the computed set of time-course vocabularies can be interrogated for a potential causal network that can shed light on the underlying interactions. The method is coupled with an experiment for investigating responses to high doses of ionizing radiation with and without a small priming dose. From a computational perspective, inference of a causal network can rapidly become computationally intractable with the increasing number of variables. Additionally, from a bioinformatics perspective, larger networks always hinder interpretation. Therefore, our method focuses on inferring the simplest network that is computationally tractable and interpretable. The method first reduces the number of temporal variables through consensus clustering to reveal a small set of temporal templates. It then enforces simplicity in the network configuration through the sparsity constraint, which is further regularized by requiring continuity between consecutive time points. We present intermediate results for each computational step, and apply our method to a time-course transcriptome dataset for a cell line receiving a challenge dose of ionizing radiation with and without a prior priming dose. Our analyses indicate that (i) the priming dose increases the diversity of the computed templates (e.g., diversity of transcriptome signatures); thus, increasing the network complexity; (ii) as a result of the priming dose, there are a number of unique templates with delayed and oscillatory profiles; and (iii) radiation-induced stress responses are enriched through pathway and subnetwork studies.
