Observations (up to E similar to 10MeV) show clearly the behavior of the outer electron radiation belt at different timescales: months-long periods of gradual inward radial diffusive transport and weak loss being punctuated by dramatic flux changes driven by strong solar wind transient events. We present analysis of multi-MeV electron flux and phase space density (PSD) changes during March 2013 in the context of the first year of Van Allen Probes operation. This March period demonstrates the classic signatures both of inward radial diffusive energization and abrupt localized acceleration deep within the outer Van Allen zone (L similar to 4.00.5). This reveals graphically that both competing mechanisms of multi-MeV electron energization are at play in the radiation belts, often acting almost concurrently or at least in rapid succession. Key Points Clear observations to higher energy than ever before Precise detection of where and how acceleration takes place Provides new eyes on megaelectron Volt C1 [Baker, D. N.; Jaynes, A.

TI Event-specific chorus wave and electron seed population models in DREAM3D using the Van Allen Probes SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article DE DREAM3D; event-specific; Van Allen Probes ID RADIATION-BELT ELECTRONS; RELATIVISTIC ELECTRONS; GEOMAGNETIC STORMS; MAGNETIC STORMS; DIFFUSION-COEFFICIENTS; INNER MAGNETOSPHERE; ACCELERATION; DYNAMICS; FIELD AB The DREAM3D diffusion model is applied to Van Allen Probes observations of the fast dropout and strong enhancement of MeV electrons during the October 2012 double-dip storm. We show that in order to explain the very different behavior in the two dips, diffusion in all three dimensions (energy, pitch angle, and L-*) coupled with data-driven, event-specific inputs, and boundary conditions is required. Specifically, we find that outward radial diffusion to the solar wind-driven magnetopause, an event-specific chorus wave model, and a dynamic lower-energy seed population are critical for modeling the dynamics. In contrast, models that include only a subset of processes, use statistical wave amplitudes, or rely on inward radial diffusion of a seed population, perform poorly. The results illustrate the utility of the high resolution, comprehensive set of Van Allen Probes' measurements in studying the balance between source and loss in the radiation belt, a principal goal of the mission. Key Points DREAM3D uses event-specific driving conditions measured by Van Allen Probes Electron dropout is due to outward radial diffusion to compressed magnetopause Event-specific chorus and seed electrons are necessary for the enhancement C1 [Tu, Weichao; Cunningham, G.

TI Effect of EMIC waves on relativistic and ultrarelativistic electron populations: Ground- based and Van Allen Probes observations SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article DE EMIC waves; relativistic electrons; ultra-relativistic electrons; Van Allen Probes; pitch-angle diffusion; loss ID GEOMAGNETIC STORMS; BELT AB We study the effect of electromagnetic ion cyclotron (EMIC) waves on the loss and pitch angle scattering of relativistic and ultrarelativistic electrons during the recovery phase of a moderate geomagnetic storm on 11 October 2012. The EMIC wave activity was observed in situ on the Van Allen Probes and conjugately on the ground across the Canadian Array for Real-time Investigations of Magnetic Activity throughout an extended 18 h interval. However, neither enhanced precipitation of >0.7MeV electrons nor reductions in Van Allen Probe 90 degrees pitch angle ultrarelativistic electron flux were observed. Computed radiation belt electron pitch angle diffusion rates demonstrate that rapid pitch angle diffusion is confined to low pitch angles and cannot reach 90 degrees. For the first time, from both observational and modeling perspectives, we show evidence of EMIC waves triggering ultrarelativistic (similar to 2-8MeV) electron loss but which is confined to pitch angles below around 45 degrees and not affecting the core distribution. Key Points EMIC wave activity is not associated with precipitation of MeV electrons EMIC waves do not deplete the ultra-relativistic belt down to 90 degrees EMIC waves cause loss of low pitch angle electrons with energies similar to 2-8 MeV C1 [Usanova, M.

Delayed triggering may be even more common, but the mechanisms are not well understood. Catalogs of repeating earthquakes, earthquakes that recur repeatedly at the same location, provide ideal data sets to test the effects of transient dynamic perturbations on the timing of earthquake occurrence. Here we employ a catalog of 165 families containing similar to 2500 total repeating earthquakes to test whether dynamic perturbations from local, regional, and teleseismic earthquakes change recurrence intervals. The distance to the earthquake generating the perturbing waves is a proxy for the relative potential contributions of static and dynamic deformations, because static deformations decay more rapidly with distance. Clear changes followed the nearby 2004 M(w)6 Parkfield earthquake, so we study only repeaters prior to its origin time. We apply a Monte Carlo approach to compare the observed number of shortened recurrence intervals following dynamic perturbations with the distribution of this number estimated for randomized perturbation times. We examine the comparison for a series of dynamic stress peak amplitude and distance thresholds. The results suggest a weak correlation between dynamic perturbations in excess of similar to 20kPa and shortened recurrence intervals, for both nearby and remote perturbations. Key Points We found weak correlation of perturbations and shortened recurrences The weak correlation exists for perturbations > similar to 20 KPa The weak correlation exists for both nearby and remote perturbations C1 [Wu, Chunquan; Johnson, Paul] Los Alamos Natl Lab, Geophys Lab, Los Alamos, NM 87545 USA.

When the Atlantic Multidecadal Oscillation (AMO) index is added to the set of explanatory variables, the fraction of accounted for temperature variance increases to 94%. The anthropogenic effects account for about two thirds of the post-1975 global warming with one third being due to the positive phase of the AMO. In comparison, the Coupled Models Intercomparison Project Phase 5 (CMIP5) ensemble mean accounts for 87% of the observed global mean temperature variance. Some of the CMIP5 models mimic the AMO-like oscillation by a strong aerosol effect. These models simulate the twentieth century AMO-like cycle with correct timing in each individual simulation. An inverse structural analysis suggests that these models generally overestimate the greenhouse gases-induced warming, which is then compensated by an overestimate of anthropogenic aerosol cooling. Key Points The AMO is a more effective predictor than ENSO for global mean temperature AMO-related processes contribute about one third to the post-1975 global warming Radiative forcing due to volcanic aerosol is alredy encoded in the AMO C1 [Chylek, Petr; Dubey, Manvendra K.; Hengartner, Nicolas] Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

A robust spring-drying signal across multiple models is identified in the Southwest that results from a decrease in P and an increase in E in the future. In the boreal winter and summer, the prominent changes in P-E are associated with a north-south dipole pattern, while in spring, the prominent changes in P-E appear as an east-west dipole pattern. The progression of the north-south and east-west dipole patterns through the seasons manifests clearly as a seasonal clockwise migration of wet/dry patterns, which is a robust feature of water availability changes in North America consistent across regional and global climate simulations.

This study automates the search for observable predictors using data from phase 5 of the Coupled Model Intercomparison Project. The primary focus of this paper is assessing statistical significance of the resulting predictive relationships. Failure to account for dependence between models, variables, locations, and seasons is shown to yield misleading results. A new technique for testing the field significance of data-mined correlations which avoids these problems is presented. Using this new approach, all 41,741 relationships we tested were found to be explainable by chance. This leads us to conclude that data mining is best used to identify potential relationships which are then validated or discarded using physically based hypothesis testing. Key Points Correlation magnitude is not sufficient proof of predictive skill Significance testing is complicated by model nonindependence in ensembles The best predictors of climate change are related to the Southern Ocean C1 [Caldwell, Peter M.; Zelinka, Mark D.; Klein, Stephen A.; Santer, Benjamin D.] Lawrence Livermore Natl Lab, Livermore, CA 94550 USA.

TI Tracking elevated pollution layers with a newly developed hyperspectral Sun/Sky spectrometer (4STAR): Results from the TCAP 2012 and 2013 campaigns SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article DE air-pollution; Biomass-burning; sunphotometery; hyperspectral; trace-gases ID AIRBORNE SUN PHOTOMETER; COLUMNAR WATER-VAPOR; SOLAR TRANSMITTANCE MEASUREMENTS; SPECTRAL-RESOLUTION LIDAR; ABSORPTION CROSS-SECTION; AEROSOL CLASSIFICATION; AIRCRAFT MEASUREMENTS; UNITED-STATES; SOLVE-II; ACE-ASIA AB Total columnar water vapor (CWV), nitrogen dioxide (NO2), and ozone (O-3) are derived from a newly developed, hyperspectral airborne Sun-sky spectrometer (4STAR) for the first time during the two intensive phases of the Two-Column Aerosol Project (TCAP) in summer 2012 and winter 2013 aboard the DOE G-1 aircraft. We compare results with coincident measurements. We find 0.045g/cm(2) (4.2%) negative bias and 0.28g/cm(2) (26.3%) root-mean-square difference (RMSD) in water vapor layer comparison with an in situ hygrometer and an overall RMSD of 1.28g/m(3) (38%) water vapor amount in profile by profile comparisons, with differences distributed evenly around zero. RMSD for O-3 columns average to 3%, with a 1% negative bias for 4STAR compared with the Ozone Measuring Instrument along aircraft flight tracks for 14 flights during both TCAP phases. Ground-based comparisons with Pandora spectrometers at the Goddard Space Flight Center, Greenbelt, Maryland, showed excellent agreement between the instruments for both O-3 (1% RMSD and 0.1% bias) and NO2 (17.5% RMSD and -8% bias). We apply clustering analysis of the retrieved products as a case study during the TCAP summer campaign to identify variations in atmospheric composition of elevated pollution layers and demonstrate that combined total column measurements of trace gas and aerosols can be used to define different pollution layer sources, by comparing our results with trajectory analysis and in situ airborne miniSPLAT (single-particle mass spectrometer) measurements. Our analysis represents a first step in linking sparse but intense in situ measurements from suborbital campaigns with total column observations from space. C1 [Segal-Rosenheimer, M.; Russell, P.

However, one of the known side effects of stratospheric injections of sulfate aerosols under present-day conditions is a general decrease in ozone concentrations. Here we present the results from two general circulation models and two coupled chemistry-climate models within the experiments G3 and G4 of the Geoengineering Model Intercomparison Project. On average, the models simulate in G4 an increase in sulfate aerosol surface area density similar to conditions a year after the Mount Pinatubo eruption and a decrease in globally averaged ozone by 1.1-2.1 DU (Dobson unit, 1 DU = 0.001 atm cm) during the central decade of the experiment (2040-2049). Enhanced heterogeneous chemistry on sulfate aerosols leads to an ozone increase in low and middle latitudes, whereas enhanced heterogeneous reactions in polar regions and increased tropical upwelling lead to a reduction of stratospheric ozone. The increase in UV-B radiation at the surface due to ozone depletion is offset by the screening due to the aerosols in the tropics and midlatitudes, while in polar regions the UV-B radiation is increased by 5% on average, with 12% peak increases during springtime. The contribution of ozone changes to the tropopause radiative forcing during 2040-2049 is found to be less than -0.1 W m(-2). After 2050, because of decreasing ClOx concentrations, the suppression of the NOx cycle becomes more important than destruction of ozone by ClOx, causing an increase in total stratospheric ozone. Key Points Different processes affect ozone in stratospheric sulfate aerosol geoengineering Suppression of NOx cycle becomes more important than ClOx depleting cycle Polar UV-B increases by 5% annually and 12% in spring C1 [Pitari, Giovanni; De Luca, Natalia; Di Genova, Glauco; Mancini, Eva] Univ Aquila, Dept Phys & Chem Sci, I-67100 Laquila, Italy.

For illustrative purposes, we apply this approach to a Taylor homogenization model of fcc poly-crystalline materials and show that the spectral representation of crystal plasticity is ideal for parallel implementations aimed at next-generation large-scale microstructure-sensitive simulations of material deformation. We find that multi-thread parallelizations of the algorithm provide two orders of magnitude acceleration of the calculation, whereas graphics processing unit-based computing solutions allow for three orders of magnitude speedup factors over the conventional model.

TI A multiscale mass scaling approach for explicit time integration using proper orthogonal decomposition SO INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING LA English DT Article DE explicit dynamics; multiscale; POD; mass scaling ID MODEL-REDUCTION; DYNAMICS; FLOWS; POD AB One of the main computational issues with explicit dynamics simulations is the significant reduction of the critical time step as the spatial resolution of the finite element mesh increases. In this work, a selective mass scaling approach is presented that can significantly reduce the computational cost in explicit dynamic simulations, while maintaining accuracy. The proposed method is based on a multiscale decomposition approach that separates the dynamics of the system into low (coarse scales) and high frequencies (fine scales). Here, the critical time step is increased by selectively applying mass scaling on the fine scale component only. In problems where the response is dominated by the coarse (low frequency) scales, significant increases in the stable time step can be realized. In this work, we use the proper orthogonal decomposition (POD) method to build the coarse scale space. The main idea behind POD is to obtain an optimal low-dimensional orthogonal basis for representing an ensemble of high-dimensional data. In our proposed method, the POD space is generated with snapshots of the solution obtained from early times of the full-scale simulation. The example problems addressed in this work show significant improvements in computational time, without heavily compromising the accuracy of the results. Copyright (c) 2013 John Wiley & Sons, Ltd.

TI Prismatic punching defects in CdTe compounds SO JOURNAL OF CRYSTAL GROWTH LA English DT Article DE Defects; Bridgman technique; Cadmium compounds; Semiconducting II-VI materials ID CDZNTE; DETECTORS AB The origin and nature of star-shaped prismatic punching defects (PPDs) were analyzed by white-beam X-ray diffraction topography (WBXDT) and photoluminescence (PL) measurements. PPDs were observed in CdTe-based compounds that had Te-rich secondary phase defects and were annealed only under Cd overpressure. The evolutional features of the PPDs during annealing were similar to those of a diffusion process, that is, the in-diffusion of Cd vapor via Cd vacancies. PL mapping around the PPDs reveals that the stoichiometry of PPDs is the same as that of a normal matrix, and that PPDs are just structural defects with non-radiative emission induced by the exothermic reaction between Cd and Te. We find that Te-rich secondary phase defects can be removed without the generation of star-shaped PPDs, if the exothermic reaction rate can be slowed down to reduce the thermal gradient between the Te-rich region and the surrounding matrix.

With the H2 flow off, the indium concentration in the In chi Ga1-chi N QWs were x=0.183, x=0.163, and x=0.096 for growth temperatures of 730, 750 and 770 degrees C respective. Using these same QW growth conditions, the H2 flow was increased up to 3 SLM resulting in a gradual decrease in the indium concentration in the InyGa1-yN barriers. Kinetic analysis suggests that hydrogen enhances indium surface desorption through the formation of more volatile indium-hydride species, thereby decreasing the surface indium concentration available for incorporation into the InyGa1-yN barriers. For the MQW structures grown at 750 C, the photoluminescence (PL) wavelength blue-shifts from 477 to similar to 450 nm as the indium in the InyGa1-yN barriers increases as expected from the reduced influence of the piezoelectric fields. While a corresponding increase of spontaneous emission from the increasing overlap of electron states within the QW is also expected, the PL intensity of the QW instead decreases. This conflicting expectation of increased spontaneous emission and the observation of decreased PL intensity suggest either decreases in the QW-barrier height or increases in non-radiative defects offset any efficiency gains obtained when lnGaN barriers to reduce polarization fields within the QWs.

The ability of the "NiOOH" active material to deliver an approximately ideal charge and discharge facilitated a coulometric and thermodynamic analysis through which the charge/discharge mechanisms were determined from known enthalpies of formation. The (dis)charge states were confirmed with in situ Raman spectroscopy. The mechanisms were additionally evaluated with respect to pH and potential dependence, charge quantities, hysteresis, and fluoride ion partial inhibition of the charge mechanism. The results indicate that the "NiOOH" (dis)charges as a solid-state system with mechanisms consistent with known nickel and oxygen redox reactions. A defect chemistry mechanism known for the LiNiO2 system also occurs for "NiOOH" to cause both high activity and hysteresis. Similar to other cation insertion nickel oxides, the activity of the lNiOOH" mechanism is predominantly due to oxygen redox activity and does not involve the Ni4+ oxidation state. The "NiOOH" was produced from cathodic electrodeposition of Ni(OH)(2) from nickel nitrate solutions onto highly oriented pyrolytic graphite at ideal electrodeposition current efficiencies and the deposition mechanism was also characterized.

In this invited review, we apply a molecular-level understanding of chemical precursor reactivity to reliably control the morphology, composition and intimate architecture (core/shell vs. alloyed) of semiconductor nanocrystals. We also describe our work aimed at achieving highly selective, low-temperature photochemical methods for the synthesis of semiconductor-metal and semiconductor-metal oxide photocatalytic nanocomposites. In addition, we describe our work on surface modification of semiconductor nanocrystal quantum dots using new approaches and methods that bypass ligand exchange, retaining the nanocrystal's native ligands and original optical properties, as well as on spectroscopic methods of characterization useful in determining surface ligand organization and chemistry. Using recent examples from our group and collaborators, we demonstrate how these efforts have lead to faster, wider and more systematic application of semiconductor nanocrystal-based materials to biological imaging and tracking, and to photocatalysis of unconventional substrates. We believe techniques and methods borrowed from inorganic chemistry (including coordination, organometallic and solid state chemistry) have much to offer in reaching a better understanding of the synthesis, functionalization and real-life application of such exciting materials as semiconductor nanocrystals (quantum-dots, rods, tetrapods, etc).

More recently, however, the field has evolved beyond straightforward particle-size control to embrace more complex NQD heterostructures. As a result of the inclusion of internal, nanoscale compositional interfaces, heterostructured NQDs afford opportunities for enhanced, emergent and even multi-functional behavior and properties. A common structural motif for achieving such 'engineered' NQDs is to envelop the NQD core within a shell of a different composition. Herein, a summary of our recent research in the development, synthesis, characterization and application of 'core/shell' NQDs is provided. In the first part, enhancement of properties is demonstrated through our work in lead chalcogenide core/shell NQDs. In a subsequent section, emergence of novel properties resulting from specific combinations of core and shell physical and electronic structures is described in the context of non-blinking behavior and suppressed Auger recombination realized for our "giant" NQDs. Examples in this case entail both CdSe and InP cores. Application of these ultra-stable NQDs in the area of light-emission technologies is also demonstrated and discussed. Finally, multi-functionality is shown for the case of a coupled magnetic-semiconductor Co/CdSe core/shell nanocrystal system. (C) 2013 Elsevier B.V. All rights reserved.

TI Effects of dissimilatory sulfate reduction on Fe-III (hydr)oxide reduction and microbial community development SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID GREEN RUST FORMATION; NOV SP-NOV; REDUCING BACTERIA; GEN-NOV; MARINE SEDIMENT; FATTY-ACIDS; SUBSURFACE SEDIMENTS; ANAEROBIC BACTERIUM; CHEMICAL-REDUCTION; SURFACE-CHEMISTRY AB Although dissimilatory iron and sulfate reduction (DIR and DSR) profoundly affect the biogeochemical cycling of C, Fe, and S in subsurface systems, the dynamics of DIR and DSR in the presence of both Fe-III (hydr)oxides and sulfate have not been well-studied with mixed microbial populations. This study examined the response of native microbial communities in subsurface sediment from the U.S. Department of Energy's Integrated Field Research Challenge site in Rifle, CO to the availability of sulfate and specific Fe-III (hydr)oxide minerals in experimental systems containing lactate as the electron donor, with ferrihydrite, goethite, or lepidocrocite and high (10.2 mM) or low (0.2 mM) sulfate as electron acceptors. We observed rapid fermentation of lactate to acetate and propionate. Fe-III reduction was slow and limited in the presence of low-sulfate, but the extent of Fe-III reduction increased more than 10 times with high-sulfate amendments. Furthermore, the extent of Fe-III reduction was higher in ferrihydrite or lepidocrocite incubations than in goethite incubations. Propionate produced during fermentation of lactate was used as the electron donor for DSR. The concurrence of sulfate reduction and Fe-II production suggests that Fe-II production was driven primarily by reduction of Fe-III by biogenic sulfide. X-ray absorption fine-structure analysis confirmed the formation of ferrous sulfide and the presence of O-coordinated ferrous species. 16S rRNA-based microbial community analysis revealed the development of distinct communities with different Fe-III (hydr)oxides. These results highlight the highly coupled nature of C, Fe, and S biogeochemical cycles during DIR and DSR and provide new insight into the effects of electron donor utilization, sulfate concentration, and the presence of specific Fe-III (hydr)oxide phases on microbial community development.

TI Synthesis of mesostructured stishovite from FDU-12/carbon composite SO MICROPOROUS AND MESOPOROUS MATERIALS LA English DT Article DE FDU-12; Stishovite; Mesostructure; Carbon; Small-angle X-ray diffraction ID INDUCED AMORPHIZATION; SIO2 STISHOVITE; HEAT-CAPACITY; COESITE; BOUNDARY AB Nanocasting at high pressure has been recently proposed as a novel strategy for the synthesis of periodic mesoporous materials with crystalline walls. In this study we present results on the synthesis of mesostructured stishovite from mesostructured FDU-12/carbon composite precursor using the multi-anvil press. Results from quenched experiments performed at a pressure of 14 GPa indicate that a minimum temperature of 500 degrees C is needed to crystallize stishovite from the amorphous silica precursor with a preserved mesostructure. Transmission electron microscopy combined with small angle X-ray scattering measurements confirmed the mesostructure of synthetic stishovite having carbon-filled pores with a diameter of similar to 19 nm similar to the pore size of the FDU-12 precursor. Calcination of the stishovite/carbon composite at 450 degrees C in air at ambient condition leads to amorphization of the stishovite. Our results show that mesostructure materials can be synthesized at very high pressures without loss or critical modification of the mesostructure. (C) 2014 Elsevier Inc. All rights reserved.

The technique uses an innovative wavelet cospectral decomposition of fluxes into their positive and negative components. Results show that both the frequency of occurrence and the intensity of upward and downward events in the wavelet cospectra, as well as the upward and downward global wavelet cospectra, are intimately tied to the scale of motion. The average frequency of occurrence of the events in both directions was close to 50% at small scales, with the main component dominating at larger scales. The averaged normalized global intensity of the main component of scalar wavelet cospectrum has a prominent peak at 30-70s varying with the interested fluxes and the atmospheric stability, and decreases sharply for larger scales and more gradually for smaller scales. The intensity of the minor component is almost constant in the fine scales, and decreases to almost zero as the scale increases. Results from these analyses are indirectly supported by techniques such as the quadrant-hole analysis and the Fourier cospectrum. These properties suggest that the main component of wavelet cospectrum dominating at larger scales has a more important contribution to fluxes than the minor component. These results support the idea that the scalar exchange takes place mostly through the action of large-scale eddies. (C) 2013 Elsevier B.V. All rights reserved.

Strengths of 160 MPa and elongations up to 8% were measured. Post-deformation electron microscopy indicates a lack of intragranular dislocation confinement. While strength does increase with decreasing grain size, the size effect for hexagonal Mg is not as strong as that reported for face-centered cubic metals. Strength appears to be governed by a lack of dislocation pile-up as well as texture and Peierls effects. (C) 2013 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved. C1 [Sharon, J.

Both powder and single crystal X-ray diffraction data were used to refine the crystal structures. Yb2CuGe6 crystallizes in the monoclinic space group C2/m in the La2AlGe6 type structure. The lattice parameters are a = 8.0011(16) angstrom, b = 8.1962(16) angstrom, c = 10.682(2) angstrom and beta = 100.63(3). The crystal structure of Yb2CuGe6 can be described as the intergrowth of fragments Ge dimmers and zig-zag Ge chains. Yb3Cu4Ge4 crystallizes in the orthorhombic space group Immm in the Gd3Cu4Ge4 type structure. The lattice parameters are a = 4.1302(8) angstrom, b = 6.5985(13) angstrom and c = 13.691(3) angstrom. X-ray absorption near edge spectroscopy (XANES) measurements indicate that Yb in Yb2CuGe6 and Yb3Cu4Ge4 exists as intermediate and trivalent states, respectively. The structural refinement of Yb2CuGe6 is corroborated by total energy calculations within the local density approximation. (C) 2013 Elsevier B.V. All rights reserved.

TI Impact of flow rates and electrode specifications on degradations during repeated startups and shutdowns in polymer-electrolyte membrane fuel cells SO JOURNAL OF POWER SOURCES LA English DT Article DE Segmented PEM fuel cell; Corrosion of carbon support; Catalyst layer; Spatially resolved degradation; Startup and shutdown ID CARBON CORROSION; INTERNAL CURRENTS; PEMFC; HETEROGENEITIES; DURABILITY; PLATINUM; LAYER; MEA AB Separate testing protocols for fuel cell startup (SU) and shutdown (SD) are developed to distinguish between the effects of SU and SD on performance degradation. The internal currents during SU and SD operation are measured in a segmented cell to evaluate the charge exchanged between the active (H-2/Air) and passive (Air/Air) portions of the cell. Cells with different membrane-electrode assemblies (MEAs) are subjected to SU or SD sequences to evaluate the time evolution of spatially resolved decrease of performance and electrochemical active surface area (ECSA). We examine the influence of the cathode and anode Pt loading, and the type of carbon for cathode catalyst support. Both the CO2 emissions and the charges exchanged increase with the common residence time of air and hydrogen in the anode compartment. However, the evolved CO2 accounts for less than 25% of the total exchanged charge. Startups are consistently more damaging than the shutdowns, evidenced by more evolved CO2 and charge exchanged, severe ECSA decrease, and higher performance losses. (C) 2013 Elsevier B.V.

Part II of the work examined the sealing glass stability, microstructure development, interfacial reaction, and volatility issues of a 3-cell stack with LSM-based cells. After 6000 h of testing, the refractory sealing glass YSO7 showed desirable chemical compatibility with YSZ electrolyte in that no discernable interfacial reaction was identified. In addition, no glass penetration into the thin electrolyte was observed. At the aluminized AISI441 interface, the protective alumina coating appeared to be corroded by the sealing glass. Air side interactions appeared to be more severe than fuel side interactions. Metal species such as Cr, Mn, and Fe were detected in the glass, but were limited to the vicinity of the interface. No alkaline earth chromates were found at the air side. Volatility was also studied in a similar glass and weight loss in a wet reducing environment was determined. Using the steady-state volatility data, the life time weight loss of refractory sealing glass YSO77 was estimated to be less than 0.1 wt%. (C) 2013 Published by Elsevier B.V.

However, capacity degradation and voltage fading remain the major challenges for LMR cathodes prior to their practical applications. Here, we demonstrate that anion receptor, tris(pentafluorophenyl)borane ((C6F5)(3)B, TPFPB), substantially enhances the stability of electrode/electrolyte interface and thus improves the cycling stability of LMR cathode Li/Li0.2Ni0.2Mn0.6]O-2. In the presence of 0.2 M TPFPB, Li[Li0.2Ni0.2Mn0.6]O-2 shows an improved capacity retention of 76.8% after 500 cycles. It is proposed that TPFPB effectively confines the highly active oxygen species released from structural lattice through its strong coordination ability and high oxygen solubility. The electrolyte decomposition caused by the oxygen species attack is therefore largely mitigated, forming reduced amount of byproducts on the cathode surface. Additionally, other salts such as insulating LiF derived from electrolyte decomposition are also soluble in the presence of TPFPB. The collective effects of TPFPB mitigate the accumulation of parasitic reaction products and stabilize the interfacial resistances between cathode and electrolyte during extended cycling, thus significantly improving the cycling performance of Li[Li0.2Ni0.2Mn0.6]O-2.

Cas9 has been harnessed as a powerful tool for genome editing and gene regulation in many eukaryotic organisms. We report 2.6 and 2.2 angstrom resolution crystal structures of two major Cas9 enzyme subtypes, revealing the structural core shared by all Cas9 family members. The architectures of Cas9 enzymes define nucleic acid binding clefts, and single-particle electron microscopy reconstructions show that the two structural lobes harboring these clefts undergo guide RNA-induced reorientation to form a central channel where DNA substrates are bound. The observation that extensive structural rearrangements occur before target DNA duplex binding implicates guide RNA loading as a key step in Cas9 activation.

Li and W. H. Miller, J. Chem. Phys. 137, 154107 (2012)]. To properly describe vibrational quantum effects in the transport characteristics, we introduce a simple transformation rewriting the Hamiltonian in terms of occupation numbers and use a binning function to facilitate quantization. The approach provides accurate results for the nonequilibrium Holstein model for a range of bias voltages, vibrational frequencies, and temperatures. It also captures the hallmarks of vibrational quantum effects apparent in step-like structure in the current-voltage characteristics at low temperatures as well as the phenomenon of Franck-Condon blockade.

TI Observation of the slow, Debye-like relaxation in hydrogen-bonded liquids by dynamic light scattering SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID GLASS-TRANSITION; PROTON-TRANSFER; ALCOHOLS; CONDUCTIVITY; SIMULATIONS; GROTTHUSS; BEHAVIOR AB The slow, Debye-like relaxation in hydrogen-bonded liquids has largely remained a dielectric phenomenon and has thus far eluded observation by other experimental techniques. Here we report the first observation of a slow, Debye-like relaxation by both depolarized dynamic light scattering (DLS) and dielectric spectroscopy in a model hydrogen- bonded liquid, 2-ethyl-4-methylimidazole (2E4MIm). The relaxation times obtained by these two techniques are in good agreement and can be well explained by the Debye model of rotational diffusion. On the one hand, 2E4MIm is analogous to the widely studied monohydroxy alcohols in which transient chain-like supramolecular structure can be formed by hydrogen bonding. On the other hand, the hydrogen-bonded backbone of 2E4MIm is much more optically polarizable, making it possible to apply light scattering to study the dynamics of the supramolecular structure. These findings provide the missing evidence of the slow, Debye-like relaxation in DLS and open the venue for the application of dynamic light scattering to the study of supramolecular structures in hydrogen- bonded liquids.

Electron affinities of 12 468(2) cm(-1) for CH2CN and 12 402(2) cm(-1) for CD2CN are obtained, demonstrating greater precision than previous experiments. New vibrational structure is resolved for both neutral species, especially activity of the v5 hydrogen umbrella modes. The v6 out-of-plane bending mode fundamental frequency is measured for the first time in both systems and found to be 420(10) cm(-1) for CH2CN and 389(8) cm(-1) for CD2CN. Some rotational structure is resolved, allowing for accurate extraction of vibrational frequencies. Temperature-dependent SEVI spectra show marked effects ascribed to controlled population of low-lying anion vibrational levels. We directly measure the inversion splitting between the first two vibrational levels of the anion v5 umbrella mode in both species, finding a splitting of 130(20) cm(-1) for CH2CN- and 81(20) cm(-1) for CD2CN-. Franck-Condon forbidden activity is observed and attributed to mode-specific vibrational autodetachment from the CH2CN- and CD2CN- dipole bound excited states. We also refine the binding energy of the anion dipole bound states to 39 and 42 cm(-1), respectively, for CH2CN- and CD2CN-. (C) 2014 AIP Publishing LLC.

Herein, we examine the latter class of interaction in the context of CO2 binding to benzene. We begin by clarifying the geometry of the CO2-benzene complex. We then generate a benchmark binding curve using a coupled-cluster approach with single, double, and perturbative triple excitations [CCSD(T)] at the complete basis set (CBS) limit. Against this Delta CCSD(T) CBS standard, we evaluate a plethora of electronic structure approximations: Hartree-Fock, second-order Moller-Plesset perturbation theory (MP2) with the resolution-of-the-identity approximation, attenuated MP2, and a number of density functionals with and without different empirical and nonempirical van der Waals corrections. We find that finite-basis MP2 significantly overbinds the complex. On the other hand, even the simplest empirical correction to standard density functionals is sufficient to bring the binding energies to well within 1 kJ/mol of the benchmark, corresponding to an error of less than 10%; PBE-D in particular performs well. Methods that explicitly include nonlocal correlation kernels, such as VV10, vdW-DF2, and.omega B97X-V, perform with similar accuracy for this system, as do.omega B97X and M06-L.

CA Pierre Auger Collaboration TI Probing the radio emission from air showers with polarization measurements SO PHYSICAL REVIEW D LA English DT Article ID MONTE-CARLO SIMULATIONS; COSMIC-RAYS; CODALEMA; DETECTOR; PULSES; THUNDERSTORMS; RADIATION; SIGNALS; FIELD AB The emission of radio waves from air showers has been attributed to the so-called geomagnetic emission process. At frequencies around 50 MHz this process leads to coherent radiation which can be observed with rather simple setups. The direction of the electric field induced by this emission process depends only on the local magnetic field vector and on the incoming direction of the air shower. We report on measurements of the electric field vector where, in addition to this geomagnetic component, another component has been observed that cannot be described by the geomagnetic emission process. The data provide strong evidence that the other electric field component is polarized radially with respect to the shower axis, in agreement with predictions made by Askaryan who described radio emission from particle showers due to a negative charge excess in the front of the shower. Our results are compared to calculations which include the radiation mechanism induced by this charge-excess process.

One of the reasons that makes it difficult to identify the rupture origin is the coexistence of two dewetting mechanisms, namely, thermal nucleation and spinodal instability, as observed in many experimental studies. Using a coarse-grained model and large-scale molecular dynamics simulations, we are able to characterize the very early stage of dewetting in nanometer-thick liquid-metal films wetting a solid substrate. We observe the features characteristic of both spinodal instability and thermal nucleation in the spontaneously dewetting films and show that these two macroscopic mechanisms share a common origin at molecular levels.

This study investigates adding a graphite susceptor to an energetic composite consisting of aluminum (Al) and iron (III) oxide (Fe2O3) and examines microwave coupling to the sample. In a companion study, the combustion of this thermite as a function of susceptor concentration was also studied to evaluate the trade-off between enhancing microwave coupling and flame propagation speed. Results show that graphite enhances microwave coupling up to 10% by mass concentration but reduces heating at higher percentages that exceed a percolation threshold. As susceptor concentrations increased greater than one mass percent, the flame propagation speed correspondingly decreased. (C) 2014 AIP Publishing LLC. C1 [Crane, C.

Evidence taken from the experimentally measured wavelength dependence of the breakdown threshold suggests that the material excitation mechanisms mainly consist of a sequence of one-photon absorptions between short-lived vibronic defect states spanning the band gap with a quasi-continuum of states. The transition between excitation paths involving different number of photons yields information about the role of temperature in determining the width of the transition and corresponding threshold conduction band density prior to initiation of breakdown. This physical system is well adapted to study a plasma warming up at solid density leading to the so-called warm dense matter. (C) 2014 AIP Publishing LLC.

Such resonant states have the potential to greatly improve thermoelectric energy conversion efficiency by increasing the density of states variation near the Fermi level, thereby increasing the Seebeck coefficient at a given carrier concentration. Through transport measurements of the Seebeck coefficient, electrical conductivity, thermal conductivity, and Hall coefficient, we show that a practical band resonant state is not achieved by Sn doping. Compared to undoped CoSb3, the dimensionless figure of merit (ZT) in Sn-doped CoSb3 is enhanced slightly at high temperatures to a value of 0.2, mostly due to a reduction in thermal conductivity. The Fermi level is calculated not to reach the band resonant state induced by Sn impurity atoms within the range of Sn concentrations examined here. (C) 2014 AIP Publishing LLC.

Three different quantities of helium, 400 appm, 1000 appm, and 5000 appm, were pre-injected directly into TEM foils at 400 degrees C. The samples containing helium were then irradiated in-situ with 1 MeV Kr2+ at 400 degrees C to a final dose of 5.4 dpa (displacement per atom). Cavities were formed from the helium injection solely and the cavity density and size increased with increasing helium dosage. In contrast to previous heavy ion irradiations with cold pre-injected helium, heterogeneous nucleation of cavities was observed. During the ensuing heavy ion irradiation, dynamical observation showed noticeable size increase in cavities which nucleated close to the grain boundaries. A "bubble-void" transformation was observed after Kr2+ irradiation to high dose (5.4 dpa) in samples containing 1000 appm and 5000 appm helium. Cavity distribution was found to be consistent with in-reactor neutron irradiation induced cavity microstructures. This implies that the distribution of helium is greatly dependent on the injection temperature, and helium pre-injection at high temperature is preferred for simulating the migration of the transmutation produced helium.

I SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID MATERIAL INCONEL X-750; MICROSTRUCTURAL EVOLUTION; DAMAGE; ALLOYS; METALS; COPPER; TEM AB In order to understand radiation damage in the nickel based superalloy Inconel X-750 in thermal reactors, where (n, alpha) transmutation reaction also occurred in addition to fast neutron induced atomic displacement, heavy ion (1 MeV Kr2+) irradiation with pre-injected helium was performed under in-situ observations of an intermediate voltage electron microscope at Argonne National Laboratory. By comparing to our previous studies using 1 MeV Kr2+ irradiation solely, the pre-injected helium was found to be essential in cavity nucleation. Cavities started to be visible after Kr2+ irradiation to 2.7 dpa at >= 200 degrees C in samples containing 200 appm, 1000 appm, and 5000 appm helium, respectively, but not at lower temperatures. The cavity growth was observed during the continuous irradiation. Cavity formation appeared along with a reduced number density of stacking fault tetrahedra, vacancy type defects. With higher pre-injected helium amount, a higher density of smaller cavities was observed. This is considered to be the result of local trapping effect of helium which disperses vacancies. The average cavity size increases with increasing irradiation temperatures; the density reduced; and the distribution of cavities became heterogeneous at elevated temperatures. In contrast to previous characterization of in-reactor neutron irradiated Inconel X-750, no obvious cavity sink to grain boundaries and phase boundaries was found even at high doses and elevated temperatures. MC-type carbides were observed as strong sources for agglomeration of cavities due to their enhanced trapping strength of helium and vacancies. (C) 2014 AIP Publishing LLC.

TI A Kinetic Monte Carlo model for material aging: Simulations of second phase formation at Au/Bi2Te3 junction in oxygen environments SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID THERMODYNAMIC REASSESSMENT; BISMUTH TELLURIDE; AU-BI; SYSTEM; DIFFUSION AB Electronic properties of semiconductor devices are sensitive to defects such as second phase precipitates, grain sizes, and voids. These defects can evolve over time especially under oxidation environments and it is therefore important to understand the resulting aging behavior in order for the reliable applications of devices. In this paper, we propose a kinetic Monte Carlo framework capable of simultaneous simulation of the evolution of second phases, precipitates, grain sizes, and voids in complicated systems involving many species including oxygen. This kinetic Monte Carlo model calculates the energy barriers of various events based directly on the experimental data. As a first step of our model implementation, we incorporate the second phase formation module in the parallel kinetic Monte Carlo codes SPPARKS. Selected aging simulations are performed to examine the formation of second phase precipitates at the eletroplated Au/Bi2Te3 interface under oxygen and oxygen-free environments, and the results are compared with the corresponding experiments.

These diverse compounds reduce lignocellulosic biofuel yields by inhibiting cellular processes and diverting energy into cellular responses. LCH inhibitors present one of the most significant challenges to efficient biofuel production by microbes. Development of new strains that lessen the effects of LCH inhibitors is an economically favorable strategy relative to expensive detoxification methods that also can reduce sugar content in deconstructed biomass. Systems biology analyses and metabolic modeling combined with directed evolution and synthetic biology are successful strategies for biocatalyst development, and methods that leverage state-of-the-art tools are needed to overcome inhibitors more completely. This perspective considers the energetic costs of LCH inhibitors and technologies that can be used to overcome their drain on conversion efficiency. We suggest academic and commercial research groups could benefit by sharing data on LCH inhibitors and implementing "translational biofuel research."

Here we describe a recipe for the controlled production of highly regular "5-5-8" line defects in graphene by means of simultaneous electron irradiation and Joule heating by applied electric current. High-resolution transmission electron microscopy reveals individual steps of the growth process. Extending earlier theoretical work suggesting valley-discriminating capabilities of a graphene 5-5-8 line defect, we perform first-principles calculations of transport and find a strong energy dependence of valley polarization of the charge carriers across the defect. These findings inspire us to propose a compact electrostatically gated "valley valve" device, a critical component for valleytronics. C1 [Chen, J. -H.; Alem, N.; Louie, S.

TI Magnetic Reconnection in Plasma under Inertial Confinement Fusion Conditions Driven by Heat Flux Effects in Ohm's Law SO PHYSICAL REVIEW LETTERS LA English DT Article ID LASER-PRODUCED PLASMAS; FIELDS; DISSIPATION; IMPLOSIONS; TRANSPORT; EQUATION AB In the interaction of high-power laser beams with solid density plasma there are a number of mechanisms that generate strong magnetic fields. Such fields subsequently inhibit or redirect electron flows, but can themselves be advected by heat fluxes, resulting in complex interplay between thermal transport and magnetic fields. We show that for heating by multiple laser spots reconnection of magnetic field lines can occur, mediated by these heat fluxes, using a fully implicit 2D Vlasov-Fokker-Planck code. Under such conditions, the reconnection rate is dictated by heat flows rather than Alfvenic flows. We find that this mechanism is only relevant in a high beta plasma. However, the Hall parameter omega(c)tau(ei) can be large so that thermal transport is strongly modified by these magnetic fields, which can impact longer time scale temperature homogeneity and ion dynamics in the system.

This system can be considered as a prototype of a QD supercrystal. Following the computational strategies given in our recent work [I.-H. Chu et al., J. Phys. Chem. C 115, 21409 (2011)], we have investigated the effects of molecular attachment, molecular isomer (trans and cis), and QD size on the electron hopping rate using Marcus theory. Our results indicate that molecular attachment has a large impact on the system for both isomers. In the most energetically favorable attachment, the cis isomer provides significantly greater coupling between the two QDs and hence the electron hopping rate is greater compared to the trans isomer. As a result, the carrier mobility of the QD array in the low carrier density, weak external electric-field regime is several orders of magnitude higher in the cis compared to the trans configuration. This demonstration of mobility modulation using QDs and azobenzene could lead to an alternative type of switching device.

TI Numerical simulations of electrostatically driven jets from nonviscous droplets SO PHYSICAL REVIEW E LA English DT Article ID BOUNDARY INTEGRAL METHOD; ELECTRIC-FIELD; CHARGED DROPS AB The evolution of a perfectly conducting and nonviscous fluid, under the action of an electric field (uniform at infinity), is studied numerically. Level set techniques are employed to develop an Eulerian potential flow model that can follow the drop evolution past breakup, while the free surface fluid velocity and the electric field force are obtained via axisymmetric boundary integral calculations. Numerical results are presented for neutral and charged droplets and for free charged droplets. In all cases, the evolution droplet aspect ratio, progeny droplet size, Taylor cone angles, jet shapes, and self-similar scaling exponents are reported. In particular, for free charged water droplets, the bursting frequency and other jetting characteristics have been carefully analyzed. Wherever possible, these results are compared with previously reported experiments and simulations. C1 [Garzon, M.] Univ Oviedo, Dept Appl Math, Oviedo, Spain. [Gray, L.

TI Two-atom Rydberg blockade using direct 6S to nP excitation SO PHYSICAL REVIEW A LA English DT Article ID ALKALI-METAL ATOMS; CESIUM; STATE; IONS AB We explore a single-photon approach to Rydberg state excitation and Rydberg blockade. Using detailed theoretical models, we show the feasibility of direct excitation, predict the effect of background electric fields, and calculate the required interatomic distance to observe Rydberg blockade. We then measure and control the electric field environment to enable coherent control of Rydberg states. With this coherent control, we demonstrate Rydberg blockade of two atoms separated by 6.6(3) mu m. When compared with the more common two-photon excitation method, this single-photon approach is advantageous because it eliminates channels for decoherence through photon scattering and ac Stark shifts from the intermediate state while moderately increasing Doppler sensitivity.

TI Limits on the accuracy of force sensing at short separations due to patch potentials SO PHYSICAL REVIEW D LA English DT Article ID INVERSE-SQUARE LAW; CASIMIR FORCE; MU-M; CONSTRAINTS; PHYSICS AB Recent theoretical developments in gravitational physics have motivated experimental searches for violations of Newton's inverse square law of gravity at small separations. There has also been considerable theoretical and experimental progress in establishing the Casimir effect. These two classes of experiments and others in fundamental physics measure the forces between polycrystalline metals at micron-order separations, and are thus susceptible to forces due to electrostatic patch fields on their surfaces. We develop the theory for the patch force power spectra which provides the necessary tools to estimate the magnitude of random patch signals. We apply our results to two experiments intending to measure nonNewtonian gravitational signals using the isoelectronic technique where the mean effect of patches is nullified by design but random patch signals may still spoil the measurement sensitivity. Our results help gauge the sensitivity limitations of real experimental setups and the analytical formulas we derive suggest useful strategies for engineering and minimizing undesired patch effects in future experiments.

Whether coherent (ballistic) transport occurs in nature and whether it improves photosynthetic efficiency remain topics of debate. Here, we use a non-equilibrium Green's function analysis to model exciton transport after excitation from an incoherent source (as opposed to coherent laser excitation). We find that even with an incoherent source, the rate of environmental dephasing strongly affects exciton transport efficiency, suggesting that the relationship between dephasing and efficiency is not an artifact of coherent excitation. The Green's function analysis provides a clear view of both the pattern of excitonic fluxes among chromophores and the multidirectionality of energy transfer that is a feature of coherent transport. We see that even in the presence of an incoherent source, transport occurs by qualitatively different mechanisms as dephasing increases. Our approach can be generalized to complex synthetic systems and may provide a new tool for optimizing synthetic light harvesting materials.

The simulated solubilities and trend in terms of Henry's law constants agree qualitatively with the experiment. Polar gases such as H2S and nonpolar gases with a large quadrupole moment such as CO2 show the highest solubility, while nonpolar gases of small quadrupole moments (such as N-2 and H-2) are least soluble. The solute-ionic liquid interaction correlates with the observed solubility order. We also examined the temperature dependence of solubility for CO, and N-2 and found that the CO2 solvation in IL is exothermic with a negative solvation enthalpy, while the N-2 solvation is endothermic, in agreement with the experiment.

The calculated mobility is shown to be highly anisotropic, consistent with the tetragonal symmetry of the xenotime crystal structure. Due to the presence of one-dimensional channels along the c-axis, the hopping rate is significantly enhanced along this direction. Specifically, the activation energy for hopping along the a- and b-axes is computed to be 0.45 eV away from aliovalent dopant impurities, while the calculated energy barrier within the channels that run along the c-axis is 0.15 eV. The corresponding hopping rates along the c-axis channels are more than 2 orders of magnitude larger than those calculated previously for the monoclinic monazite-structured LaPO4 compound. The effects of aliovalent dopants on proton migration have also been investigated, considering the case of Ca2+ substitution for Dy3+. These calculations reveal a dopant-proton binding energy of approximately 0.4 eV and an increase in the hopping barriers near the dopant by up to 0.2 eV. These dopant effects were found to be relatively localized, with minimal changes to the energetics of the protons obtained more than approximately 5 angstrom away from the aliovalent impurity.

The structural mechanisms of pressure-induced densification and the corresponding evolution of physical properties of glassy GeSe4 alloy are studied over pressures ranging between ambient and 32.5 GPa, using X-ray scattering supplemented with 3D Monte Carlo structural modeling, Raman spectroscopy, electrical conductivity, and P-V equation of state measurements. The results demonstrate a pressure-induced, hysteretically reversible transition between low-density semiconducting and high-density metallic amorphous phases of GeSe4 near similar to 10-15 GPa. These two phases are characterized by their distinct P V equations of state and structural mechanisms of densification. Densification in the low-density phase is dominated by large inward shifting of the second neighbors with a small amount of conversion from edge-sharing to corner-sharing GeSe4 tetrahedra. On the other hand, densification in the high-density phase involves a gradual increase in the nearest-neighbor coordination numbers of Ge and Se atoms and the formation of Ge Ge bonds between adjacent polyhedral units. These structural transformations are accompanied by a pressure-induced metallization that is rerersible. C1 [Kalkan, Bora] Lawrence Berkeley Natl Lab, Adv Light Source, Berkeley, CA USA.

The battery chemistry is based on chloroaluminate ionic liquid electrolytes, which allow reversible stripping and plating of aluminum metal at the negative electrode. Characterization of electrochemically synthesized polypyrrole films revealed doping of the polymers with chloroaluminate anions. Cycling of the conducting polymer electrodes occurred via the electrochemical insertion and removal of these anions. Stable galvanostatic cycling of polypyrrole and polythiophene cells was demonstrated, with electrode capacities at near-theoretical levels (30-100 mAh g(-1)) and Coulombic efficiencies approaching 100%. The energy density of a sealed sandwich-type cell with polythiophene at the positive electrode was estimated to be 44 Wh kg(-1) relative to the total mass of active components. This energy density is competitive with state-of-the-art battery chemistries for grid-scale energy storage. C1 Sandia Natl Labs, Adv Power Sources Res & Dev, Albuquerque, NM 87185 USA.

We find the resonant Auger results to be independent of film morphology and likely dominated by localized structure rather than extended chain interactions. We show that the degree of excited state localization onto the benzothiadiazole acceptor group in each polymer is similar, suggesting that that the differences in IQE between these two polymers are not explained by the electronic structure of the LUMO.

POSS can be synthesized with a wide variety of functional ligands attached to their surfaces. Here we report the results of a comprehensive study of the crystal structure and ligand dynamics of one of the simplest POSS nanoparticles, octamethyl-POSS or Si8O12(CH3)(8), where the central Si8O12 cage is surrounded by eight methyl ligands. Neutron powder diffraction data highlight the presence of strongly temperature-dependent methyl group rotational dynamics. Vibrational spectra were measured using Raman and inelastic neutron scattering techniques, and the results of the measurements were compared with the predictions of density functional theory calculations. In particular, the inelastic neutron scattering spectra show the fundamental and first overtone transitions of the methyl torsional vibrations; these transitions are forbidden in both Raman and infrared spectroscopy for the molecule with its ideal octahedral symmetry. The energies of these transitions are used to determine the height of the torsional energy barrier. Direct measurements of the methyl group dynamics using quasielastic incoherent neutron scattering provide the hydrogen atom jump distance and the activation energy for rotation of the methyl groups. Together these results provide a detailed picture of the structure and ligand dynamics of this POSS molecule.

Furthermore they display a large variation in their critical temperatures depending on the amount of Pt in their spacer layers: (n = 3,4). To gain more insight into the role of the spacer layer the electronic structures of the iron platinum arsenides are represented in the momentum space of the underlying Fe sublattice using a first-principles unfolding method. We find that Ca-10(FeAs)(10)(Pt4As8), contrary to Ca-10(FeAs)(10)(Pt3As8), shows a net electron doping and a non-negligible interlayer coupling. Both effects could account for the difference in the critical temperatures. C1 [Berlijn, Tom] Oak Ridge Natl Lab, Ctr Nanophase Mat Sci, Oak Ridge, TN 37831 USA.

TI Photoinduced changes in the cuprate electronic structure revealed by femtosecond time- and angle-resolved photoemission SO PHYSICAL REVIEW B LA English DT Article ID COOPER PAIRS; T-C; BI2SR2CACU2O8+DELTA; ENERGY; SUPERCONDUCTOR; DISPERSION AB The dressing of quasiparticles in solids is investigated by changes in the electronic structure E(k) driven by femtosecond laser pulses. Employing time-and angle-resolved photoemission on an optimally doped cuprate above T-c, we observe two effects with different characteristic temporal evolutions and, therefore, different microscopic origins. First, a marked change in the effective mass due to the 70-meV kink in E(k) is found to occur during the experiment's 100-fs temporal resolution and is assigned to laser-driven perturbation of an electronic interaction dressing the bare band. Second, a change in k(F) is explained by effective photodoping due to particle-hole asymmetry and offers opportunities for ultrafast optoelectronic switches based on an optically driven insulator-superconductor transition.

TI Novel Characterization of Capsule X-Ray Drive at the National Ignition Facility SO PHYSICAL REVIEW LETTERS LA English DT Article ID BALANCE; PLASMA AB Indirect drive experiments at the National Ignition Facility are designed to achieve fusion by imploding a fuel capsule with x rays from a laser-driven hohlraum. Previous experiments have been unable to determine whether a deficit in measured ablator implosion velocity relative to simulations is due to inadequate models of the hohlraum or ablator physics. ViewFactor experiments allow for the first time a direct measure of the x-ray drive from the capsule point of view. The experiments show a 15%-25% deficit relative to simulations and thus explain nearly all of the disagreement with the velocity data. In addition, the data from this open geometry provide much greater constraints on a predictive model of laser-driven hohlraum performance than the nominal ignition target. C1 [MacLaren, S.

We find that depending on the details these may occur on either the transition metal or stannate sides of the interface and in the later case can be shifted away from the interface by ferroelectricity. We also present calculations for bulk KNbO3, KTaO3, CaSnO3, BaSnO3 and ZnSnO3, showing the different transport and optical properties that may be expected on the two sides of such interfaces. The results suggest that these interfaces may display a wide range of behaviors depending on conditions, and in particular the interplay with ferroelectricity suggests that electrical control of these properties may be possible.

However, non-coding DNA elements that control the expression of developmentally important genes remain poorly defined. Here we investigate the regulation of Fezf2, a transcription factor that is necessary for the generation of deep-layer cortical projection neurons. Results: Using a combination of chromatin immunoprecipitation followed by high throughput sequencing (ChIP-seq) we mapped the binding of four deep-layer-enriched transcription factors previously shown to be important for cortical development. Building upon this we characterized the activity of three regulatory regions around the Fezf2 locus at multiple stages throughout corticogenesis. We identified a promoter that was sufficient for expression in the cerebral cortex, and enhancers that drove reporter gene expression in distinct forebrain domains, including progenitor cells and cortical projection neurons. Conclusions: These results provide insight into the regulatory logic controlling Fezf2 expression and further the understanding of how multiple non-coding regulatory domains can collaborate to control gene expression in vivo.

TI Comparisons of Shewanella strains based on genome annotations, modeling, and experiments SO BMC SYSTEMS BIOLOGY LA English DT Article DE Constraint-based model; Electron acceptors; Phenotype; FBA ID ESCHERICHIA-COLI; ONEIDENSIS MR-1; SYSTEMS BIOLOGY; GENUS; PATHWAYS AB Background: Shewanella is a genus of facultatively anaerobic, Gram-negative bacteria that have highly adaptable metabolism which allows them to thrive in diverse environments. This quality makes them an attractive bacterial target for research in bioremediation and microbial fuel cell applications. Constraint-based modeling is a useful tool for helping researchers gain insights into the metabolic capabilities of these bacteria. However, Shewanella oneidensis MR-1 is the only strain with a genome-scale metabolic model constructed out of 21 sequenced Shewanella strains. Results: In this work, we updated the model for Shewanella oneidensis MR-1 and constructed metabolic models for three other strains, namely Shewanella sp. MR-4, Shewanella sp. W3-18-1, and Shewanella denitrificans OS217 which span the genus based on the number of genes lost in comparison to MR-1. We also constructed a Shewanella core model that contains the genes shared by all 21 sequenced strains and a few non-conserved genes associated with essential reactions. Model comparisons between the five constructed models were done at two levels - for wildtype strains under different growth conditions and for knockout mutants under the same growth condition. In the first level, growth/no-growth phenotypes were predicted by the models on various carbon sources and electron acceptors. Cluster analysis of these results revealed that the MR-1 model is most similar to the W3-18-1 model, followed by the MR-4 and OS217 models when considering predicted growth phenotypes. However, a cluster analysis done based on metabolic gene content revealed that the MR-4 and W3-18-1 models are the most similar, with the MR-1 and OS217 models being more distinct from these latter two strains. As a second level of comparison, we identified differences in reaction and gene content which give rise to different functional predictions of single and double gene knockout mutants using Comparison of Networks by Gene Alignment (CONGA). Here, we showed how CONGA can be used to find biomass, metabolic, and genetic differences between models. Conclusions: We developed four strain-specific models and a general core model that can be used to do various in silico studies of Shewanella metabolism. The developed models provide a platform for a systematic investigation of Shewanella metabolism to aid researchers using Shewanella in various biotechnology applications.

Nonporous materials able to incorporate molecules via internal lattice reorganization are however extremely rare since their structural integrity usually does not resist the guest exchange processes. The novel heteroleptic low-spin Fe(II) complex [Fe(bpp)(H2L)](ClO4)(2)center dot 1.5C(3)H(6)O (1; bpp = 2,6-bis(pyrazol-3-yl)pyridine, H2L 2,6-bis(5-(2-methoxyphenyl)pyrazol-3-yl)pyridine) crystallizes as a compact discrete, nonporous material hosting solvate molecules of acetone. The system is able to extrude one-third of these molecules to lead to [Fe(bpp)(H2L)](ClO4)(2)center dot C3H6O (2), switching to the high-spin state while experiencing a profound crystallographic change. Compound 2 can be reversed to the original material upon reabsorption of acetone. Single crystal X-ray diffraction experiments on the latter system (1') and on 2 show that these are reversible single-crystal-to-single-crystal (SCSC) transformations. Likewise, complex 2 can replace acetone by MeOH and H2O to form [Fe(bpp)(H(2)LA(ClO4)(2)center dot 1.25MeOH:0.5H(2)O (3) through a SCSC process that also implies a switch to the spin state. The 3 -> 1 transformation through acetone reabsorption is also demonstrated. Besides the spin switching at room temperature, this series of SCSC transformations causes macroscopic changes in color that can be followed by the naked eye. The reversible exchanges of chemicals are therefore easily sensed at the temperature at which these occur, contrary to what is the case for most of the few existing nonporous spin-based sensors, which feature a large temperature gap between the process monitored and the mechanism of detection.

Typically, ammonia or hydrogen is used as an etchant gas in the mixture to remove carbon that otherwise passivates the catalyst surface and impedes growth. Our demonstration of the use of air as the etchant gas opens up the possibility that ion etching could be sufficient to maintain the catalytic activity state during synthesis. It also demonstrates a path toward growing VACNFs in the open atmosphere. C1 [Kodumagulla, A.; Varanasi, V.; Pearce, R. C.; Wu, W. C.; Tracy, J. B.; Melechko, A.

The results indicate a nonequilibrium lithium insertion and extraction in the LiFePO4 cathode, with neither the LiFePO4 phase nor the FePO4 phase maintaining a static composition during lithium insertion/extraction. On the basis of our observations, we propose that the LiFePO4 cathode simultaneously experiences both a two-phase reaction mechanism and a dual-phase solid-solution reaction mechanism over the entire range of the flat voltage plateau, with this dual-phase solid-solution behavior being strongly dependent on charge/ discharge rates. The proposed dual-phase solid-solution mechanism may explain the remarkable rate capability of LiFePO4 in commercial cells.

The functionalization of polymeric backbone after its development brings unique selectivity towards the target biomolecules. In present work, the functionalities of choice have been introduced through the ring-opening of allyl glycidyl ether. The utility of polymer is widened through derivatizations to immobilized metal ion affinity chromatographic (IMAC) material for the phosphopeptides enrichment and Reversed Phase (C-18) for the desalting prior to MALDI-MS analysis. The polymer-IMAC in addition to Fe3+ is also immobilized with lanthanide ions like La3+, Eu3+, and Er3+. The amount of Fe3+ immobilized is determined as 0.7928 mg/g. Spherical morphology with narrow particle size dispersion is revealed by scanning electron microscopy (SEM). The surface area, pore volume and size distribution is determined by nitrogen adsorption porosimetery. The elemental composition and purity level is confirmed by energy dispersive X-ray spectroscopy (EDX) data. The derivatization to IMAC and RP is evaluated by Fourier transform infrared (FT-IR) spectroscopy. The polymer enables the efficient phosphopeptide enrichment to equal degree from casein variants, non-fat milk, egg yolk, human serum, and HeLa cell extract. The identification of phosphorylation sites can lead to the phosphorylation pathways to understand the post-translational modifications. The identification with their sequence coverage is made using Mascot and Phosphosite Plus. It is sensitive to enrich the phosphopeptides down to 2 femtomoles with very high selectivity of 1:2000 with BSA background. These attributes are linked to the higher surface area (173.1554 m(2)/g) of the designed polymer. The non-specific bindings, particularly the Fe3+ linked acidic residues are also avoided. Four characteristic phosphopeptides (fibrinopeptide A and their hydrolytic products) from fibrinogen alpha-chain are identified from the human serum after the enrichment, which have link to the hepatocellular carcinoma (HCC). The proportions of fibrinogen and their phosphorylation products enriched by poly(AGE/DVB)-IMAC open new horizons in the biomarker discovery.

We first recast the existing 8 TeV monojet search at CMS in terms of a SUSY simplified model with only light gauginos (winos and binos) or only light Higgsinos. The current searches are not sensitive to MSSM-like production cross sections, but would be sensitive to models with 2-20 times enhanced production cross section, for particle masses between 100 GeV and 250 GeV. Then we explore the sensitivity in the 14 TeV run of the LHC. Here we emphasise that in addition to the pure monojet search, soft leptons present in the samples can be used to increase the sensitivity. Exclusion of electroweakino masses up to 200 GeV is possible with 300 fb(-1) at the LHC, if the systematic error can be reduced to the 1% level. Discovery is possible with 3000 fb(-1) in some regions of parameter space. C1 [Schwaller, Pedro] CERN, Div Theory, CH-1211 Geneva 23, Switzerland.

Tests performed below 122 K have shown that the material breaks in a random fashion already in the elastic region, while above it a clearly pronounced yield point is observed. This sudden change of the mechanical behavior has been rationalized on the basis of atomistic simulations, addressing the interaction of dislocations with Cu precipitates. The latter study has revealed the presence of bcc to fcc transition induced by dislocations which is a temperature dependent process. It is suppressed with increasing temperature and enhanced with increasing a precipitate size. This transition, efficient at low temperature, leads to the transformation of Cu precipitates into non-coherent particles, which act as stronger obstacles and cause the experimentally observed premature failure. The presence of small non-coherent Cu-precipitates, expected to form according to atomistic predictions, and not observed prior to deformation, was confirmed by means of transmission electron microscopy.

TI Temperature and grain size dependent plastic instability and strain rate sensitivity of ultrafine grained austenitic Fe-14Cr-16Ni alloy SO MATERIALS SCIENCE AND ENGINEERING A-STRUCTURAL MATERIALS PROPERTIES MICROSTRUCTURE AND PROCESSING LA English DT Article DE Austenitic Fe-Cr-Ni alloy; Ultrafine grain; Temperature; Plastic instability; Strain rate sensitivity ID STAINLESS-STEELS; NANOCRYSTALLINE NI; ACTIVATION VOLUME; DEFORMATION; BEHAVIOR; STRESS; METALS; MECHANISMS; ENERGY; IRON AB In this study temperature and grain size dependent plastic instability and strain rate sensitivity (SRS) were investigated for coarse grained (CG) and ultrafine grained (UFG) austenitic Fe-14Cr-16Ni alloys. As tensile testing temperature increased from 20 to 200 degrees C, UFG alloys exhibited much more prominent decrease of uniform strain compared with CG counterparts. Transmission electron microscopy (TEM) analysis of deformed UFG alloys revealed temperature dependent evolution of microstructures. Through grain refinement, the SRS of Fe-14Cr-16Ni alloy increased and activation volume decreased, which may be related to the interactions of dislocations with grain boundaries. The SRS of UFG alloys exhibited greater temperature dependence than CG alloys. (C) 2014 Elsevier B.V. All rights reserved. C1 [Sun, C.; Ma, J.; Hartwig, K.

Each microstructure was also evaluated to determine grain size, martensite volume fraction (MVF), and retained austenite content. Nanoindentation hardnesses and quantitative microstructural measurements were correlated with tensile properties and performance in hole expansion tests to assess the importance of the individual constituent properties. Hole expansion samples were prepared with both sheared edges produced by mechanical punching, and non-deformed edges produced by electric discharge machining (EDM). Average material hardness based on nanoindentation data correlated directly to Vickers hardness measurements, verifying the capability of the nanoindentation technique to produce data consistent with traditional hardness measurements. Yield strength (YS) correlated directly to ferrite hardness indicating that, for a similar MVF and microstructural morphology, the YS is controlled by the strength of the softer matrix phase (ferrite). Hole expansion ratios (HER) on EDM samples decreased with an increase in both martensite and ferrite hardness, indicating that EDM HER values can be enhanced by softening both constituents. Punched-hole HER values decreased with increasing martensite hardness and martensite-to-ferrite hardness ratio, but were independent of ferrite hardness, indicating that softening the martensite while increasing the ferrite hardness could produce a higher HER.

TI Structural, magnetic, and superconducting properties of pulsed-laser-deposition-grown La1.85Sr0.15CuO4/La2/3Ca1/3MnO3 superlattices on (001)-oriented LaSrAlO4 substrates SO PHYSICAL REVIEW B LA English DT Article ID THIN-FILMS; THICKNESS DEPENDENCE; LA2-XSRXCUO4 FILMS; PEROVSKITES; TEMPERATURE; INTERFACE; TRANSPORT; OXIDES; BUFFER; LAYERS AB Epitaxial La1.85Sr0.15CuO4/ La2/ 3Ca1/ 3MnO3 ( LSCO/ LCMO) superlattices on ( 001)-oriented LaSrAlO4 substrates have been grown with pulsed laser deposition technique. Their structural, magnetic, and superconducting properties have been determined with in situ reflection high-energy electron diffraction, x-ray diffraction, specular neutron reflectometry, scanning transmission electron microscopy, electric transport, and magnetization measurements. We find that despite the large mismatch between the in-plane lattice parameters of LSCO (a = 0.3779 nm) and LCMO (a = 0.387 nm) these superlattices can be grown epitaxially and with a high crystalline quality. While the first LSCO layer remains clamped to the LaSrAlO4 substrate, a sizable strain relaxation occurs already in the first LCMO layer. The following LSCO and LCMO layers adopt a nearly balanced state in which the tensile and compressive strain effects yield alternating in-plane lattice parameters with an almost constant average value. No major defects are observed in the LSCO layers, while a significant number of vertical antiphase boundaries are found in the LCMOlayers. The LSCO layers remain superconducting with a relatively high superconducting onset temperature of T onset c approximate to 36 K. The macroscopic superconducting response is also evident in the magnetization data due to a weak diamagnetic signal below 10 K for H parallel to ab and a sizable paramagnetic shift for H parallel to c that can be explained in terms of a vortex-pinning-induced flux compression. The LCMO layers maintain a strongly ferromagnetic state with a Curie temperature of T Curie approximate to 190 K and a large low-temperature saturation moment of about 3.5(1) mu(B) per Mn ion. These results suggest that the LSCO/ LCMO superlattices can be used to study the interaction between the antagonistic ferromagnetic and superconducting orders and, in combination with previous studies on YBa2Cu3O7-x/ La2/ 3Ca1/ 3MnO3 superlattices, may allow one to identify the relevant mechanisms.

We find that for the underdopedmaterials with coexisting superconducting and antiferromagnetic orders, spin rotational symmetry is explicitly broken at the ordering momentum Q(1) = (pi,0). Only the longitudinal susceptibility exhibits the resonance mode, whereas a spin-wave Goldstone mode develops in the transverse component. Meanwhile, at the frustrated momentum Q2 = (0,pi), the susceptibility becomes isotropic in spin space and the magnetic resonance exists for both components. Furthermore, the resonance energies at Q(1) and Q(2) have distinct scales, which provide a natural explanation for the recently observed double resonance peaks. In addition, we show that near optimal doping the existence of strong magnetic fluctuations, which are modeled here via a Gaussian mode, can still induce the spin anisotropy in the magnetic susceptibility.

Fission coincidences were measured with a parallel-plate avalanche counter and used tomeasure the prompt fission. gamma-ray spectrum in this region to accurately characterize background. The resulting (n,gamma) cross section is generally in agreement with current evaluations. The experimental method utilizes much more detailed information than past measurements on Pu-239 and can be used to extend the measurement to higher incident neutron energies.

TI Nanoparticle Diffusion in Polymer Nanocomposites SO PHYSICAL REVIEW LETTERS LA English DT Article ID ANOMALOUS DIFFUSION; MOLECULAR-DYNAMICS; ACTIN NETWORKS; MELTS; VISCOSITY; SUBDIFFUSION; SIMULATIONS; SEMIDILUTE; NANOSCALE; BREAKDOWN AB Large-scale molecular dynamics simulations show that nanoparticle (NP) diffusivity in weakly interacting mixtures of NPs and polymer melts has two very different classes of behavior depending on their size. NP relaxation times and their diffusivities are completely described by the local, Rouse dynamics of the polymer chains for NPs smaller than the polymer entanglement mesh size. The motion of larger NPs, which are comparable to the entanglement mesh size, is significantly slowed by chain entanglements, and is not describable by the Stokes-Einstein relationship. Our results are in essentially quantitative agreement with a force-level generalized Langevin equation theory for all the NP sizes and chain lengths explored, and imply that for these lightly entangled systems, activated NP hopping is not important.

The rise of the x-ray scattering amplitude from a second x-ray pulse probes the transition from dense cryogenic molecular hydrogen to a nearly uncorrelated plasmalike structure, indicating an electron-ion equilibration time of similar to 0.9 ps. The rise time agrees with radiation hydrodynamics simulations based on a conductivity model for partially ionized plasma that is validated by two-temperature density-functional theory.

Nanopillar arrays fabricated at a higher accelerating voltage give a lower value of coercivity and ion damage does not broaden the switching field distribution (SFD). The 'edge damage' model was employed in micromagnetic simulations to investigate the reversal mechanism and SFD. The results shows that the edge damage can change the switching mode from coherent rotation to nucleation followed by rapid domain wall motion, and the broad SFD mainly comes from the intrinsic anisotropy distribution, rather than size distribution. In addition, the angle dependence of the switching field measurement shows that nanopillars with damaged edges have Stoner-Wohlfarth behaviour, which indicates that fitting the Stoner-Wohlfarth curve does not necessarily mean coherent rotation. It is the comparison between the field for domain wall motion and the nucleation field that determines the location of angle dependence curves.

While two-way reversible shape memory (RSM) is observed upon heating and cooling cycles, the one-way RSM occurs upon heating only. Shape reversibility is achieved through partial melting of a crystalline scaffold which secures memory of a temporary shape by leaving a latent template for recrystallization. This behavior is neither mechanically nor structurally constrained, thereby allowing for multiple switching between encoded shapes without applying any external force, which was demonstrated for different shapes including hairpin, coil, origami, and a robotic gripper. Fraction of reversible strain increases with cross-linking density, reaching a maximum of ca. 70%, and then decreases at higher cross-linking densities. This behavior has been shown to correlate with efficiency of securing the temporary shape.

Both BDS and SAXS detect the existence of an interfacial polymer layer on the surface of nanoparticles. The results show that whereas the calorimetric glass transition temperature varies only weakly with nanoparticle loading, the segmental mobility of the polymer interfacial layer is slower than the bulk polymer by 2 orders of magnitude. Detailed analysis of BDS and SAXS data reveal that the interfacial layer has a thickness of 4-6 nm irrespective of the nanoparticle concentration. These results demonstrate that in contrast to some recent articles on polymer nanocomposites, the interfacial polymer layer is by no means a "dead layer". However, its existence might provide some explanation for controversies surrounding the dynamics of polymer nanocomposites.

This new method is obtained by deriving a canonical model for reaction equilibrium and incorporating it into the previously reported Gibbs ensemble unit-cell SCFT for investigating macrophase separation. We use our new technique to attack the phase behavior of an incompressible melt blend of AB diblock copolymers that reversibly react at their B termini with monofunctional B homopolymers to produce longer ABB diblock copolymers. We find that reaction equilibrium favoring the product polymer stabilizes a rich variety of ordered phases with little macrophase separation. Reaction equilibrium favoring the reactants, however, leads to macrophase separation over a broad range of compositions.

High-throughput methods for measuring fundamental electrochemical properties are demonstrated through the investigation of oxygen-evolution catalysis by using 665 oxide compositions containing nickel, iron, cobalt, and cerium. The behavior of each composition is characterized in 1.0 M NaOH(aq) by using a scanning drop three-electrode cell to perform chronopotentiometry (CP) and cyclic voltammetry experiments. CP measurements at different current densities identify different composition-performance trends, owing to underlying variations in fundamental electrochemical behavior. We report systematic, coincident, composition- dependent trends in the Tafel slopes and the reversible redox potentials of the catalysts. Applying high-throughput electrochemical methods provides insight into composition-property- performance relationships and motivates new directions for the study of catalyst mechanisms by using informatics and theory.

While charge transport through ligand shells of nanoparticle films has been studied intensely in static dry and electrochemical systems, its influence on charge transfer kinetics in dispersed colloidal systems has received relatively less attention. This work reports the oxidation of amine passivated tungsten oxide nanoparticles by an organically soluble tris-(1,10-phenanthroline) iron(III) derivative. By following the rate of this oxidation optically via the production of the ferroin derivative under various reaction conditions and particle derivatizations, we are able to show that the fluxional ligand shells on dispersed, colloidal nanoparticles provide a separate and more facile pathway for charge transfer, in which the rate-limiting step for charge transfer is the ligand dissociation. Since such ligand shells are frequently required for nanoparticle stability, this observation has significant implications for colloidal nanoparticle photocatalysis.

In this framework, the minimal SUSY SU(5) grand unification model may be viable since heavy sfermions suppress the proton decay via color-triplet Higgs exchanges. At the same time, sizable flavor violation in sfermion masses is still allowed by low-energy precision experiments when the mass scale is as high as 0(100) TeV, which naturally explains the 125 GeV Higgs mass. In the presence of the sfermion flavor violation, however, the rates and branching fractions of proton decay can be drastically changed. In this paper, we study the effects of sfermion flavor structure on proton decay and discuss the experimental constraints on sfermion flavor violation. We find that proton-decay experiments may give us a valuable knowledge on sfermion flavor violation, and by combining it with the results from other low-energy precision experiments, we can extract insights to the structure of sfermion sector as well as the underlying grand unification model.

We synthesize colloidal nanocrystals of CsxWO3, a tungsten bronze in which electronic charge carriers are introduced by interstitial doping. By using varying ratios of oleylamine to oleic acid, we synthesize three distinct shapes of these nanocrystals hexagonal prisms, truncated cubes, and pseudospheres which exhibit strongly shape-dependent absorption features in the near-infrared region. We rationalize these differences by noting that lower symmetry shapes correlate with sharper plasmon resonance features and more distinct resonance peaks. The plasmon peak positions also shift systematically with size and with the dielectric constant of the surrounding media, reminiscent of typical properties of plasmonic metal nanoparticles.

TI Self-Doping and Electrical Conductivity in Spinel Oxides: Experimental Validation of Doping Rules SO CHEMISTRY OF MATERIALS LA English DT Article ID METAL-OXIDE; WATER; SPECTROSCOPY; GENERATION AB Self-doping of cations on the tetrahedral and octahedral sites in spinel oxides creates "anti-site" defects, which results in functional optical, electronic, magnetic, and other materials properties. Previously, we divded the III-II spinel family into four doping types (DTs) based on first-principle calculations in order to understand their electrical behavior. Here, we present experimental evidence on two prototype spinels for each major doping type (DT1 and DT4) that test the first principles calculations. For the DT-1 Ga2ZnO4 spinel, we show that the anti-site defects in a stoichiometric film are equal in concentration and compenstate each other, whereas, for nonstoichiometric Cr2MnO4, a representative DT-4 spinel, excess Mn on the tetrahedral sites becomes electrically inactive as the Mn species switch from (III) to (II). The agreement between experiment and theory validates the Doping Rules distilled from the theoretical framework and significantly enhances our understanding of the defect chemistry of spinel oxides.

The present effort uses numerically exact techniques in one-dimensional systems to report the observation of block states within the orbital-selective Mott phase regime, connecting two seemingly independent areas of research, and providing analogies with the physics of double-exchange models.

Kim, Young-June van den Brink, Jeroen TI Longer-range lattice anisotropy strongly competing with spin-orbit interactions in pyrochlore iridates SO PHYSICAL REVIEW B LA English DT Article ID HGTE QUANTUM-WELLS; MAGNETIC-PROPERTIES; BASIS-SETS; R2IR2O7 R; INSULATOR; ABSORPTION; OXIDES; PHASE; EU AB In the search for topological phases in correlated electron systems, materials with 5d transition-metal ions, in particular the iridium-based pyrochlores A2Ir2O7, provide fertile grounds. Several topological states have been predicted but the actual realization of such states is believed to critically depend on the strength of local potentials arising from distortions of the IrO6 cages. We test this hypothesis by measuring with resonant inelastic x-ray scattering the electronic level splittings in the A = Y, Eu systems, which we show to agree very well with ab initio quantum chemistry electronic-structure calculations for the series of materials with A = Sm, Eu, Lu, and Y. We find, however, that the primary source for quenching the spin-orbit interaction is not a distortion of the IrO6 octahedra but longer-range lattice anisotropies which inevitably break the local cubic symmetry.

Indeed, X-Ray FELs, with their 10-fold orders of magnitude increase in peak brightness, probably represent the best example of it New ambitious proposals for X-ray FELs and ERLs, as well as inverse Compton sources for X- or gamma-ray production, are now requiring operation at MHz-GHz repetition rates. In response to that, a number of groups around the world have been actively working in developing high-brightness high-duty cycle electron injectors capable of driving such machines. The high repetition rate requirement cannot be met by the existing low-repetition rate high-brightness injector schemes, and new technologies are under investigation. This paper includes a description of the requirements for such injectors, an overview of the pursued technologies and schemes, a description of the main beam dynamics issues associated with the different choices, and a number of examples of the results obtained so far by the groups active in the field.

An experiment is in preparation at the Photo Injector Test facility at DESY, Zeuthen site (PITZ), to demonstrate and characterize self-modulation of an electron beam. Key elements for this are the highly flexible photocathode laser system and the well-developed beam diagnostics. Preparations for the experiment have started at PITZ. In a first step a suitable insertion point for the plasma cell was determined with beam dynamics simulations. It was decided to use laser ionization to generate the plasma since this technique is capable of providing a homogeneous plasma channel with sufficient size (1 mm diameter, 60 mm length) and density (10(15) cm(-3)), Two different ways were found to generate the plasma, utilizing either field ionization with a 1 TW Ti:Sapphire laser or single photon ionization with a 400 nil ArF excimer laser. As opposed to previously realized designs the ionization laser is coupled from the side, orthogonally to the electron beam direction. (C) 2013 Elsevier B.V.

TI Rare-event trajectory ensemble analysis reveals metastable dynamical phases in lattice proteins SO PHYSICAL REVIEW E LA English DT Article ID GLOBULAR-PROTEINS; GLASS-TRANSITION; MODEL; THERMODYNAMICS; PATHWAYS; DEPENDENCE; SEQUENCES; EVOLUTION; BEHAVIOR; KINETICS AB We explore the dynamical large deviations of a lattice heteropolymer model of a protein by means of path sampling of trajectories. We uncover the existence of nonequilibrium dynamical phase transitions in ensembles of trajectories between active and inactive dynamical phases, whose nature depends on the properties of the interaction potential. We consider three potentials: two heterogeneous interaction potentials and a homogeneous Go potential. When preserving the full heterogeneity of interactions due to a given amino acid sequence, either in a fully interacting model or in a native contacts interacting model (heterogeneous Go model), the observed dynamic transitions occur between equilibrium highly native states and highly native but kinetically trapped states. A native activity is defined that allows us to distinguish these dynamic phases. In contrast, for the homogeneous Go model, where all native interaction energies are uniform and the amino acid sequence plays no role, the dynamical transition is a direct consequence of the static bistability between the unfolded and the native state. In the two heterogeneous interaction models the native-active and native-inactive states, despite their thermodynamic similarity, have widely varying dynamical properties, and the transition between them occurs even in lattice proteins whose sequences are designed to make them optimal folders.

A cathepsin-reactive warhead conjugated to a weakly basic amine and a clickable alkyne, for subsequent appendage of a fluorophore or biotin reporter tag, accumulated in lysosomes as observed by structured illumination microscopy (SIM) in J774 mouse macrophage cells. Analysis of in vivo labeled J774 cells by mass spectrometry showed that the probe was very selective for cathepsins B and Z, two lysosomal cysteine proteases. Analysis of starvation-induced autophagy, a catabolic pathway involving lysosomes, showed a large increase in the number of tagged proteins and an increase in cathepsin activity. The organelle-targeting of activity-based probes holds great promise for the characterization of enzyme activities in the myriad diseases linked to specific subcellular locations, particularly the lysosome.

It is also observed that the plasma fluctuation spectra at 1 AU show a plasma beta dependence. Reconciling these two sets of observations and using the Invariance Principle, Bhattacharjee et al. suggested that the plasma inside every flux tube may become unstable with respect to pressure-driven instabilities and gives rise to fluctuation spectra that depend on the local plasma beta. The present work is the first direct numerical simulation of such a flux tube. We solve the full magnetohydrodynamic equations using the DEBS code and show that if the plasma inside the flux tube is driven unstable by spatial inhomogeneities in the background plasma pressure, the observed nature of the fluctuating power spectra agrees reasonably well with observations, as well as the analytical prediction of Bhattacharjee et al.

For comparison purposes, conventional stainless steels with the same chemical composition were studied as well. Long-term oxidation tests were conducted at 800 C for up to 2000 h in atmospheric air. The mass-gain versus time curves were obtained and the microstructure and chemical elements distribution in different regions of the specimens after oxidation were then analyzed by SEM/EDS and XRD. The experimental results showed that an addition of yttrium to Fe-14C-3W-0.4Ti alloy sufficiently reduced the oxidation rate. However, ODS processing to precipitate nanoclusters is a more effective means of improving high-temperature oxidation rather than a simple yttrium addition. (C) 2014 Elsevier B.V.

The carrier scattering processes influence the relaxation oscillation parameters, as well as the frequency chirp, which are both important parameters when determining the modulation performance of the laser device and its reaction to optical perturbations. We find that the FM/AM response exhibits a strong dependence on the modulation frequency, which leads to a modified optical response of QD lasers when compared to conventional laser devices. Furthermore, the frequency response curve changes with the scattering time scales, which can allow for an optimization of the laser stability towards optical perturbations.

TI High fluence laser damage precursors and their mitigation in fused silica SO OPTICS EXPRESS LA English DT Article ID 351 NM; OPTICAL-MATERIALS; SURFACES; BULK; CONTAMINATION; RESISTANCE; BREAKDOWN; PULSES; GROWTH; SITES AB The use of any optical material is limited at high fluences by laser-induced damage to optical surfaces. In many optical materials, the damage results from a series of sources which initiate at a large range of fluences and intensities. Much progress has been made recently eliminating silica surface damage due to fracture-related precursors at relatively low fluences (i.e., less than 10 J/cm(2), when damaged by 355 nm, 5 ns pulses). At higher fluence, most materials are limited by other classes of damage precursors which exhibit a strong threshold behavior and high areal density (>10(5) cm(-2)); we refer to these collectively as high fluence precursors. Here, we show that a variety of nominally transparent materials in trace quantities can act as surface damage precursors. We show that by minimizing the presence of precipitates during chemical processing, we can reduce damage density in silica at high fluence by more than 100 times while shifting the fluence onset of observable damage by about 7 J/cm(2). A better understanding of the complex chemistry and physics of cleaning, rinsing, and drying will likely lead to even further improvements in the damage performance of silica and potentially other optical materials.

Experimental results clearly demonstrate huge splitting in the fundamental inductive-capacitive resonance when the incident terahertz polarization couples to the metamolecule system through the outer SRR. However, the strengths of split resonances are too weak to detect experimentally when the meta-molecule system is excited through the inner SRR. Such strongly coupled metamolecules can enable additional dispersion tuning and polarization control in metamaterials. (C) 2014 AIP Publishing LLC.

TI Kinetics of monolayer graphene growth by segregation on Pd(111) SO APPLIED PHYSICS LETTERS LA English DT Article ID POLYCRYSTALLINE GRAPHENE; SURFACE; SIMULATION; TRANSPORT AB Using in situ low-energy electron microscopy and density functional theory calculations, we follow the growth of monolayer graphene on Pd(111) via surface segregation of bulk-dissolved carbon. Upon lowering the substrate temperature, nucleation of graphene begins on graphene-free Pd surface and continues to occur during graphene growth. Measurements of graphene growth rates and Pd surface work functions establish that this continued nucleation is due to increasing C adatom concentration on the Pd surface with time. We attribute this anomalous phenomenon to a large barrier for attachment of C adatoms to graphene coupled with a strong binding of the non-graphitic C to the Pd surface. (C) 2014 AIP Publishing LLC.

We also show that hydrogen diffuses preferentially along the rutile [001] direction whereby surface orientations can be tailored for optimal transport. Finally, we show that hydrogen doping is energetically favored, but there is a 1.6 eV barrier for dissociation of hydrogen molecules on a (100) monoclinic surface.

Platforms using the whole adult organism to evaluate the genome-wide response to toxicants are especially attractive. Recent work demonstrates the feasibility of this approach in vertebrates using the experimentally robust zebrafish model. In the present study, we evaluated gene expression changes in whole adult male zebrafish following an acute 24 hr high dose exposure to three metals with known human health risks. Male adult zebrafish were exposed to nickel chloride, cobalt chloride or sodium dichromate concentrations corresponding to their respective 96 hr LC20, LC40 and LC60. Histopathology was performed on a subset of metal-exposed zebrafish to phenotypically anchor transcriptional changes associated with each metal. Results: Comparative analysis identified subsets of differentially expressed transcripts both overlapping and unique to each metal. Application of gene ontology (GO) and transcription factor (TF) enrichment algorithms revealed a number of key biological processes perturbed by metal poisonings and the master transcriptional regulators mediating gene expression changes. Metal poisoning differentially activated biological processes associated with ribosome biogenesis, proteosomal degradation, and p53 signaling cascades, while repressing oxygen-generating pathways associated with amino acid and lipid metabolism. Despite appreciable effects on gene regulation, nickel poisoning did not induce any morphological alterations in male zebrafish organs and tissues. Histopathological effects of cobalt remained confined to the olfactory system, while chromium targeted the gills, pharynx, and intestinal mucosa. A number of enriched transcription factors mediated the observed gene response to metal poisoning, including known targets such as p53, HIF1 alpha, and the myc oncogene, and novel regulatory factors such as XBP1, GATA6 and HNF3 beta. Conclusions: This work uses an experimentally innovative approach to capture global responses to metal poisoning and provides mechanistic insights into metal toxicity.

After grafting, these surface organometallic compounds are more stable than the precursor TaMe5. Treatment of 2a,b with water and H-2 resulted in the formation of methane in amount of 3.6 +/- 0.2 and 3.4 +/- 0.2 mol/grafted Ta, respectively. 2a,b react with H-2 (800 mbar) to form ( SiO)(2)TaH. After ( SiO)(2)TaH was heated to 500 degrees C under hydrogen or vacuum, [(=SiO)(3)Ta][ SiH] was produced, and the structure was confirmed by IR, NMR, and EXAFS. Considering the difficulty of the previous preparation method, these syntheses represent a facile and convenient way to prepare tantalum surface species ( SiO)(2)TaH and ( SiO)(3)Ta via the intermediate of the new surface organometallic precursors: ( SiO)TaMe4/( SiO)(2)TaMe3.

Measurements at ambient pressure reveal rich magnetic behavior, where ferromagnetic correlations are present in the paramagnetic state and a subsequent feature is seen at T-1 approximate to 22 K within the ordered state. Heat-capacity measurements additionally reveal moderately enhanced electronic correlations, as evidenced by the electronic coefficient of the specific heat gamma = 23 mJ/mol center dot K-2, which is large by comparison to closely related 122 analogs and the value predicted by electronic structure calculations. Upon the application of pressure, T-N is suppressed toward zero. For P >= 0.89 GPa, another phase transition appears at T-2 < T-N which is also suppressed by P. At P-c approximate to 1.4-1.5 GPa, T-N and T-2 drop abruptly to zero at a putative quantum phase transition. ForP > P-c, a broad shoulder in rho(T) appears at T*, which moves to higher T and broadens with increasing P. We discuss possible scenarios to understand the phase diagram and compare to other compounds which show similar P-driven behavior. C1 [Baumbach, R. E.; Sidorov, V. A.; Lu, Xin; Ghimire, N.

TI Structural, elastic, and thermal properties of cementite (Fe3C) calculated using a modified embedded atom method SO PHYSICAL REVIEW B LA English DT Article ID DENSITY-FUNCTIONAL THEORY; MOLECULAR-DYNAMICS; 1ST PRINCIPLES; ATOMISTIC SIMULATIONS; HIGH-PRESSURE; C SYSTEM; METALS; TEMPERATURE; TRANSITION; COMPRESSION AB Structural, elastic, and thermal properties of cementite (Fe3C) were studied using a modified embedded atom method (MEAM) potential for iron-carbon (Fe-C) alloys. Previously developed Fe and C single-element potentials were used to develop a Fe-C alloy MEAM potential, using a statistics-based optimization scheme to reproduce structural and elastic properties of cementite, the interstitial energies of C in bcc Fe, and heat of formation of Fe-C alloys in L-12 and B-1 structures. The stability of cementite was investigated by molecular dynamics simulations at high temperatures. The nine single-crystal elastic constants for cementite were obtained by computing total energies for strained cells. Polycrystalline elastic moduli for cementite were calculated from the single-crystal elastic constants of cementite. The formation energies of (001), (010), and (100) surfaces of cementite were also calculated. The melting temperature and the variation of specific heat and volume with respect to temperature were investigated by performing a two-phase (solid/liquid) molecular dynamics simulation of cementite. The predictions of the potential are in good agreement with first-principles calculations and experiments. C1 [Liyanage, Laalitha S.

TI Cross section and.gamma-ray spectra for U-238(n,gamma) measured with the DANCE detector array at the Los Alamos Neutron Science Center SO PHYSICAL REVIEW C LA English DT Article ID ODD-MASS NUCLEI; ACTINIDE NUCLEI; DIPOLE STRENGTH; U-238; EXCITATIONS; SIMULATION; FORMULA; TH-232; MODEL AB Background: Accurate knowledge of the U-238(n,gamma) cross section is important for developing theoretical nuclear reaction models and for applications. However, capture cross sections are difficult to calculate accurately and often must be measured. Purpose: We seek to confirm previous measurements and test cross-section calculations with an emphasis on the unresolved resonance region from 1 to 500 keV. Method: Cross sections were measured from 10 eV to 500 keV using the DANCE detector array at the LANSCE spallation neutron source. The measurements used a thin target, 48 mg/cm(2) of depleted uranium. Gamma cascade spectra were also measured to provide an additional constraint on calculations. The data are compared to cross-section calculations using the code CoH3 and cascade spectra calculations made using the code DICEBOX. Results: This new cross-section measurement confirms the previous data. The measured gamma-ray spectra suggest the need for additional low-lying dipole strength in the radiative strength function. New Hauser-Feshbach calculations including this strength accurately predict the capture cross section without renormalization. Conclusions: The present cross-section data confirm previous measurements. Including additional low-lying dipole strength in the radiative strength function may lead to more accurate cross-section calculations in nuclei where Gamma gamma has not been measured.

With explicit calculations of both real and virtual contributions, we verify, for the first time, the factorization theorem at twist 4 in NLO for the nuclear-enhanced transverse momentum weighted differential cross section and demonstrate the universality of the associated twist-4 quark-gluon correlation function. We also identify the QCD evolution equation for the twist-4 quark-gluon correlation function in a large nucleus, which can be solved to determine the scale dependence of the jet transport parameter in the study of jet quenching.

The physics of the system involves a crossover between weak and strong coupling regimes characterized by an energy scale T-B, and methods of conformal field theory therefore cannot be applied. The evolution of the entanglement in this crossover has led to many numerical studies, but has remained little understood, analytically or even qualitatively. We argue in this Letter that the correct universal scaling form of the entanglement entropy S (for an arbitrary interval of length L containing the impurity) is partial derivative S/partial derivative ln L = f(LTB). In the special case where the coupling to the impurity can be refermionized, we show how the universal function f(LTB) can be obtained analytically using recent results on form factors of twist fields and a defect massless-scattering formalism. Our results are carefully checked against numerical simulations. C1 [Vasseur, Romain] Univ Calif Berkeley, Dept Phys, Berkeley, CA 94720 USA.

In this work, electron density in TI thin films (Bi2Se3, Bi2Te3, and their alloys) were manipulated by controlling the density of electronically active native defects with particle irradiation. The measured electron concentration increases with irradiation dose but saturates at different levels for Bi2Se3 and Bi2Te3. The results are in quantitative agreement with the amphoteric defect model, which predicts that electronically active native defects shift the Fermi energy (EF) toward a Fermi stabilization level (EFS) located universally at similar to 4.9 eV below the vacuum level. Combined with thickness-dependent data, it is demonstrated that regardless of the bulk doping, the surface EF is always pinned at EFS, producing a band bending and 2DEG on TI film surfaces. Our work elucidates native defect physics of TIs with a model universally applicable to other semiconductors and has critical implications for potential device applications of TIs.

At the same time, extreme scales, increased levels of concurrency, and the advent of multicores are making programming of high-end parallel computing systems on which these simulations run challenging. Although partitioned global address space (PGAS) languages attempt to address the problem by providing a shared memory abstraction for parallel processes within a single program, the PGAS model does not easily support data coupling across multiple heterogeneous programs, which is necessary for coupled multiphysics simulations. This paper explores how multiphysics-coupled simulations can be supported by the PGAS programming model. Specifically, in this paper, we present the design and implementation of the XpressSpace programming system, which extends existing PGAS data sharing and data access models with a semantically specialized shared data space abstraction to enable data coupling across multiple independent PGAS executables. XpressSpace supports a global-view style programming interface that is consistent with the PGAS memory model, and provides an efficient runtime system that can dynamically capture the data decomposition of global-view data-structures such as arrays, and enable fast exchange of these distributed data-structures between coupled applications. In this paper, we also evaluate the performance and scalability of a prototype implementation of XpressSpace by using different coupling patterns extracted from real world multiphysics simulation scenarios, on the Jaguar Cray XT5 system at Oak Ridge National Laboratory.

TI Molecular and electronic structure of Tc-2(O2CCH3)(2)Cl-4 studied by multiconfigurational quantum chemical methods SO POLYHEDRON LA English DT Article DE Technetium; DFT; Metal-metal bonds; Optical spectroscopy; Electronic structure ID 2ND-ORDER PERTURBATION-THEORY; TRANSITION; CHEMISTRY; ATOMS; BOND AB The molecular and electronic structure, as well as the electronic absorption spectrum of Tc-2(O2CCH3)(2)Cl-4 were studied by multiconfigurational quantum chemical methods. The computed ground state geometry is in excellent agreement with the experimental structure determined by single crystal X-ray diffraction (SCXRD). The total bond order (i.e., 3.20) is consistent with the presence of a moderately strong quadruple Tc-Tc bond and is the largest bond order reported so far for a multiple Tc-Tc bonded complex. Effective bond order analysis indicates stronger it and 6 bonds for Tc-2(O2CCH3)(2)Cl-4 (i.e., 1.71 for it and 0.59 for 8) than for Tc2Cl82- (i.e., 1.68 for pi and 0.47 for delta). The electronic absorption spectrum was recorded in dichloromethane and shows three distinct bands in the range 10000-35000 cm(-1). Assignment of the bands, as well as their excitation energies and intensities were performed at the CASSCF/CASPT2 level of theory. The lowest energy band corresponds to the delta ->delta transition; the next higher energy bands are attributed to delta ->pi* and pi ->delta* transitions, respectively.

TI Determining optimal fallout shelter times following a nuclear detonation SO PROCEEDINGS OF THE ROYAL SOCIETY A-MATHEMATICAL PHYSICAL AND ENGINEERING SCIENCES LA English DT Article DE nuclear explosion; nuclear fallout; shelter in place; emergency response; acute radiation syndrome AB In the event of a single, low-yield nuclear detonation in a major urban area, rapidly providing adequate shelter to affected populations could save 10 000-100 000 individuals from a fatal exposure to fallout radiation. However, poorly sheltered individuals may remain at risk. Current guidance and prior studies are not consistent as to the timing and conditions under which poorly sheltered individuals should leave their shelters to evacuate or obtain better shelter. This study proposes methods to determine the optimal shelter time based on information potentially available following a nuclear detonation. For the case in which individuals move to an adequate shelter that can be reached within 15 min, individuals should stay in a poor-quality shelter for at most 30 min after the detonation. If adequate shelter is available nearby (within 5 min), then poorly sheltered individuals should immediately proceed to the better shelter. C1 Lawrence Livermore Natl Lab, Livermore, CA 94551 USA.

TI Oxicams Bind in a Novel Mode to the Cyclooxygenase Active Site via a Two-water-mediated H-bonding Network SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article DE Cyclooxygenase (COX) Pathway; Drug Action; Enzyme Structure; Protein Drug Interactions; X-ray Crystallography ID NONSTEROIDAL ANTIINFLAMMATORY DRUG; PROSTAGLANDIN H-2 SYNTHASE; STRUCTURAL BASIS; CRYSTAL-STRUCTURE; SELECTIVE-INHIBITION; ARACHIDONIC-ACID; NSAID BINDING; COX-2; OXYGENATION; REFINEMENT AB Background: The oxicams are anti-inflammatory drugs targeting the cyclooxygenase enzymes. Results: Crystal complexes of mCOX-2isoxicam, mCOX-2meloxicam, and oCOX-1meloxicam are solved. Conclusion: Oxicams bind to the cyclooxygenase active sites in a novel mode. Significance: The first structural description of cyclooxygenase-oxicam complexes reveal a new binding pocket of inhibitors to cyclooxygenases. Oxicams are widely used nonsteroidal anti-inflammatory drugs (NSAIDs), but little is known about the molecular basis of the interaction with their target enzymes, the cyclooxygenases (COX). Isoxicam is a nonselective inhibitor of COX-1 and COX-2 whereas meloxicam displays some selectivity for COX-2. Here we report crystal complexes of COX-2 with isoxicam and meloxicam at 2.0 and 2.45 angstroms, respectively, and a crystal complex of COX-1 with meloxicam at 2.4 angstroms. These structures reveal that the oxicams bind to the active site of COX-2 using a binding pose not seen with other NSAIDs through two highly coordinated water molecules. The 4-hydroxyl group on the thiazine ring partners with Ser-530 via hydrogen bonding, and the heteroatom of the carboxamide ring of the oxicam scaffold interacts with Tyr-385 and Ser-530 through a highly coordinated water molecule. The nitrogen atom of the thiazine and the oxygen atom of the carboxamide bind to Arg-120 and Tyr-355 via another highly ordered water molecule. The rotation of Leu-531 in the structure opens a novel binding pocket, which is not utilized for the binding of other NSAIDs. In addition, a detailed study of meloxicamCOX-2 interactions revealed that mutation of Val-434 to Ile significantly reduces inhibition by meloxicam due to subtle changes around Phe-518, giving rise to the preferential inhibition of COX-2 over COX-1.

While theoretical studies of Ne-31 generally agree on its halo nature, they differ significantly in their predictions of its properties and underlying cause (e.g., that Ne-31 has an inverted ordering of p-f orbitals). We have made a systematic theoretical analysis of possible Neon halo signatures - the first using a fully microscopic, relativistic mean field approach that properly treats positive energy orbitals (such as the valence neutron in Ne-31) self-consistently with bound levels, as well as the pairing effect that keeps the nucleus loosely bound with negative Fermi energy. Our model is the analytical continuation of the coupling constant (ACCC) method based on a relativistic mean field (RMF) theory with Bardeen-Cooper-Schrieffer (BCS) pairing approximation. We calculate neutron- and matter-radii, one-neutron separation energies, p- and f-orbital energies and occupation probabilities, and neutron densities for single-particle resonant orbitals in Ne27-31. We analyze these results for evidence of neutron halo formation in Ne-29,Ne-31. Our model predicts a p-orbit in halo structure for Ne-31, based on a radius increase from Ne-30 that is 7-8 times larger than the increase from Ne-29 to Ne-30, as well as a decrease in the neutron separation energy by a factor of similar to 10 compared to that of Ne27-30. In contrast to some other studies, our inclusion of resonances yields an inverted ordering of p and f orbitals for spherical and slightly deformed nuclei. Furthermore, we find no evidence of an s-orbit in halo in Ne-29 as recently claimed in the literature. (C) 2014 The Authors. Published by Elsevier B.V.

CA CMS Collaboration TI Searches for light- and heavy-flavour three-jet resonances in pp collisions at root s=8 TeV SO PHYSICS LETTERS B LA English DT Article DE CMS; Physics; Software; Computing ID HADRON COLLIDERS; CHIRAL COLOR; SQUARK AB A search for three-jet hadronic resonance production in pp collisions at a centre-of-mass energy of 8 TeV has been conducted by the CMS Collaboration at the LHC with a data sample corresponding to an integrated luminosity of 19.4 fb(-1). The search method is model independent, and events are selected that have high jet multiplicity and large values of jet transverse momenta. The signal models explored assume R-parity-violating supersymmetric gluino pair production and have final states with either only light-flavour jets or both light- and heavy-flavour jets. No significant deviation is found between the selected events and the expected standard model multijet and t (t) over bar background. For a gluino decaying into light-flavour jets, a lower limit of 650 GeV on the gluino mass is set at a 95% confidence level, and for a gluino decaying into one heavy- and two light-flavour jets, gluino masses between 200 and 835 GeV are, for the first time, likewise excluded.

Skokov, Vladimir V. TI Collisional energy loss above the critical temperature in QCD SO PHYSICS LETTERS B LA English DT Article ID QUASI-PARTICLE; GLUON PLASMA; CONFINEMENT; MODEL; LOOP AB We compute the collisional energy loss for a heavy quark above the critical temperature in Quantum ChromoDynamics (QCD). We work in the semi Quark-Gluon Plasma, which assumes that this region is dominated by the non-trivial holonomy of the thermal Wilson line. Relative to the result of leading order in perturbation theory, at a fixed value of the coupling constant we generically find that collisional energy loss is suppressed by powers of the Polyakov loop, 1 < 1. For small values of the loop, this suppression is linear when the heavy quark scatters off of light quarks, and quadratic when the heavy quark scatters off of gluons, or for Compton scattering.

CA CMS Collaboration TI Modification of jet shapes in PbPb collisions at root s(NN)=2.76 TeV SO PHYSICS LETTERS B LA English DT Article DE CMS; Heavy ion physics; Jet shapes ID QUARK-GLUON PLASMA; MOMENTUM DEPENDENCE; TRANSVERSE-MOMENTUM; COLLABORATION; PERSPECTIVE; SUPPRESSION; DETECTOR; MATTER AB The first measurement of jet shapes, defined as the fractional transverse momentum radial distribution, for inclusive jets produced in heavy-ion collisions is presented. Data samples of PbPb and pp collisions, corresponding to integrated luminosities of 150 mu b(-1) and 5.3 pb(-1) respectively, were collected at a nucleon-nucleon centre-of-mass energy of root s(NN) = 2.76 TeV with the CMS detector at the LHC. The jets are reconstructed with the anti-k(T) algorithm with a distance parameter R = 0.3, and the jet shapes are measured for charged particles with transverse momentum P-T > 1 GeV/c. The jet shapes measured in PbPb collisions in different collision centralities are compared to reference distributions based on the pp data. A centrality-dependent modification of the jet shapes is observed in the more central PbPb collisions, indicating a redistribution of the energy inside the jet cone. This measurement provides information about the parton shower mechanism in the hot and dense medium produced in heavy-ion collisions. (C) 2014 The Authors. Published by Elsevier B.V.

TI Effect of threading dislocation density and dielectric layer on temperature-dependent electrical characteristics of high-hole-mobility metal semiconductor field effect transistors fabricated from wafer-scale epitaxially grown p-type germanium on silicon substrates SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID MOLECULAR-BEAM EPITAXY; HIGH-QUALITY GE; SI; GAN; SI(100) AB We report the electrical characteristics of Schottky contacts and high-hole-mobility, enhancement-mode, p-channel metal semiconductor field effect transistors (MESFETs) fabricated on Ge epitaxially grown on Si substrates. The Ge film covers the entire underlying Si substrate at the wafer scale without mesas or limited-area growth. The device performance is characterized primarily as a function of threading dislocation density in the epitaxial Ge film (2 x 10(7), 5 x 10(7), 7 x 10(7), and 2 x 10(8) cm(-2)) and dielectric layers (SiO2, Al2O3, and HfO2) inserted between gate metal and Ge. The thin dielectric layers (similar to 1.3 nm) are used to unpin the Fermi level. The device performance improves with decreasing threading dislocation density and the use of HfO2. The hole mobility in the Ge film with 2 x 10(7) cm(-2) dislocation density, obtained from Hall measurements, is 1020 cm(2)/V-s. Capacitance-voltage measurements on Schottky contacts provide the energy-dependent interfacial trap density of 6 x 10(11) cm(-2) eV(-1), while current-voltage measurements provide an ON/OFF current ratio of 250. Based on the current-voltage characteristics of p-MESFETs, we have obtained an external transconductance of 7 mS/mm and low-field, effective hole-mobility of 307 cm(2)/V-s under 0.1 MV/cm at room temperature. The cut-off frequency of MESFETs is 10 GHz at 200K and 2GHz at 300K. These results compare well with other reported transistor performance. (C) 2014 AIP Publishing LLC.

CA Super-Kamiokande Collaboration TI First Indication of Terrestrial Matter Effects on Solar Neutrino Oscillation SO PHYSICAL REVIEW LETTERS LA English DT Article ID MODEL AB We report an indication that the elastic scattering rate of solar B-8 neutrinos with electrons in the Super-Kamiokande detector is larger when the neutrinos pass through Earth during nighttime. We determine the day-night asymmetry, defined as the difference of the average day rate and average night rate divided by the average of those two rates, to be [-3.2 +/- 1.1(stat) +/- 0.5(syst)]%, which deviates from zero by 2.7 sigma. Since the elastic scattering process is mostly sensitive to electron-flavored solar neutrinos, a nonzero day-night asymmetry implies that the flavor oscillations of solar neutrinos are affected by the presence of matter within the neutrinos' flight path. Super-Kamiokande's day-night asymmetry is consistent with neutrino oscillations for 4 x 10(-5) eV(2) <= Delta m(21)(2) <= 7 x 10(-5) eV(2) and large mixing values of theta(12), at the 68% C.L.

TI Tunable Phonon Polaritons in Atomically Thin van der Waals Crystals of Boron Nitride SO SCIENCE LA English DT Article ID NEAR-FIELD MICROSCOPY; GRAPHENE PLASMONS; HETEROSTRUCTURES; SPECTROSCOPY AB van der Waals heterostructures assembled from atomically thin crystalline layers of diverse two-dimensional solids are emerging as a new paradigm in the physics of materials. We used infrared nanoimaging to study the properties of surface phonon polaritons in a representative van der Waals crystal, hexagonal boron nitride. We launched, detected, and imaged the polaritonic waves in real space and altered their wavelength by varying the number of crystal layers in our specimens. The measured dispersion of polaritonic waves was shown to be governed by the crystal thickness according to a scaling law that persists down to a few atomic layers. Our results are likely to hold true in other polar van der Waals crystals and may lead to new functionalities. C1 [Dai, S.; Fei, Z.; Wagner, M.; McLeod, A. S.; Liu, M. K.; Fogler, M. M.; Basov, D.

This study first develops an integrated Monte Carlo method for simulating CO2 and brine leakage from carbon sequestration and subsequent geochemical interactions in shallow aquifers. Then, we estimate probability distributions of five risk proxies related to the likelihood and volume of changes in pH, total dissolved solids, and trace concentrations of lead, arsenic, and cadmium for two possible consequence thresholds. The results indicate that shallow groundwater resources may degrade locally around leakage points by reduced pH and increased total dissolved solids (TDS). The volumes of pH and TDS plumes are most sensitive to aquifer porosity, permeability, and CO2 and brine leakage rates. The estimated plume size of pH change is the largest, while that of cadmium is the smallest among the risk proxies. Plume volume distributions of arsenic and lead are similar to those of TDS. The scientific results from this study provide substantial insight for understanding risks of deep fluids leaking into shallow aquifers, determining the area of review, and designing monitoring networks at carbon sequestration sites.

TI Momentum and photon energy dependence of the circular dichroic photoemission in the bulk Rashba semiconductors BiTeX (X = I, Br, Cl) SO PHYSICAL REVIEW B LA English DT Article ID TOPOLOGICAL INSULATORS; PHASE AB Bulk Rashba systems BiTeX (X = I, Br, Cl) are emerging as important candidates for developing spintronics devices because of the coexistence of spin-split bulk and surface states, along with the ambipolar character of the surface charge carriers. The need to study the spin texture of strongly spin-orbit-coupled materials has recently promoted circular dichroic angular resolved photoelectron spectroscopy (CD-ARPES) as an indirect tool to measure the spin and the angular degrees of freedom. Here we report a detailed photon-energy-dependent study of the CD-ARPES spectra in BiTeX (X = I, Br, Cl). Our work reveals a large variation in the magnitude and sign of the dichroism. Interestingly, we find that the dichroic signal modulates differently for the three compounds and for the different spin-split states. These findings show a momentum and photon-energy dependence for the CD-ARPES signals in the bulk Rashba semiconductor BiTeX (X = I, Br, Cl). Finally, the outcome of our experiment indicates the important relation between the modulation of the dichroism and the phase differences between the wave functions involved in the photoemission process. This phase difference can be due to initial- or final-state effects. In the former case the phase difference results in possible interference effects among the photoelectrons emitted from different atomic layers and characterized by entangled spin-orbital polarized bands. In the latter case the phase difference results from the relative phases of the expansion of the final state in different outgoing partial waves.

We define a Genomic Observatory as an ecosystem and/or site subject to long-term scientific research, including (but not limited to) the sustained study of genomic biodiversity from single-celled microbes to multicellular organisms. An international group of 64 scientists first published the call for a global network of Genomic Observatories in January 2012. The vision for such a network was expanded in a subsequent paper and developed over a series of meetings in Bremen (Germany), Shenzhen (China), Moorea (French Polynesia), Oxford (UK), Pacific Grove (California, USA), Washington (DC, USA), and London (UK). While this community-building process continues, here we express our mutual intent to establish the GOs Network formally, and to describe our shared vision for its future. The views expressed here are ours alone as individual scientists, and do not necessarily represent those of the institutions with which we are affiliated.

CA Belle Collaboration TI Search for B-o -> p(Lambda)over-bar pi(-)gamma at Belle SO PHYSICAL REVIEW D LA English DT Article ID DETECTOR; DECAYS AB We search for the charmless B-o decay with final state particles p (Lambda) over bar pi(-)gamma using the full data sample that contains 772 x 10(6)B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. This decay is predicted to proceed predominantly via the b -> s gamma radiative penguin process with a high energy photon. No significant signal is found. We set an upper limit of 6.5 x 10(-7) for the branching fraction of B-o -> p (Lambda) over bar pi(-)gamma at the 90% confidence level.

In this study, the structural, electronic, and thermodynamic properties of magnesium dichloride hexahydrate, MgCl2 center dot 6H(2)O, and its dehydrated phases, MgCl2 center dot nH(2)O (n = 4, 2, 1), were computed within the framework of density functional theory. Densities of states were predicted, and phonon analysis using density functional perturbation theory was performed at equilibrium volume to derive isochoric thermal properties (i.e., Helmholtz free energy, entropy, and isochoric heat capacity). Isobaric thermal properties (i.e., Gibbs free energy, isobaric heat capacity, and latent heat) were also calculated within the quasi-harmonic approximation. Overall good agreement is observed between the computed thermodynamicproperties and the scarce experimental data available for these materials.

The cyclic clusters were prepared by sublimation of MoO3 and WO3 powders in a vacuum. To evaluate the cluster activity in dehydration, dehydrogenation, and condensation reactions, they were suspended in an ethanol matrix on an inert substrate, graphene monolayer on Pt(111). The reaction products formed upon heating were followed and quantified using temperature-programmed desorption. The experimental results were corroborated using coupled cluster CCSD(T) calculations at DFT optimized geometries that provide quantitative molecular-scale information on the reaction mechanisms. The dehydration and dehydrogenation of ethanol probe both the Lewis/Bronsted acid/base and redox properties of the metal centers. The overall conversion of the alcohol is governed by the Lewis acidity of the metal center, and product selectivities, as determined by the relative weights of dehydrogenation and dehydration, are governed by the reducibility of the metal center.

Using lactate as the electron donor and carbon source, and sulfate as the electron acceptor, wild type D. vulgaris shows motility on soft agar plates. We evaluated this phenotype with mutants resulting from insertional inactivation of genes potentially related to motility. Our study revealed that the cheA3 (DVU2072) kinase mutant was impaired in the ability to form motility halos. Insertions in two other cheA loci did not exhibit a loss in this phenotype. The cheA3 mutant was also non-motile in capillary assays. Complementation with a plasmid-borne copy of cheA3 restores wild type phenotypes. The cheA3 mutant displayed a flagellum as observed by electron microscopy, grew normally in liquid medium, and was motile in wet mounts. In the growth conditions used, the D. vulgaris A MA mutant (DVU3229) for FliA, predicted to regulate flagella-related genes including cheA3, was defective both in flagellum formation and in forming the motility halos. In contrast, a deletion of the flp gene (DVU2116) encoding a pilin-related protein was similar to wild type. We conclude that wild type D. vulgaris forms motility halos on solid media that are mediated by flagella-related mechanisms via the CheA3 kinase. The conditions under which the CheA1 (DVU1594) and CheA2 (DVU1960) kinase function remain to be explored.

TI Experimental and Modeling Studies of an Unusual Water-Filled Pore Structure with Possible Mechanistic Implications in Family 48 Cellulases SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID CLOSTRIDIUM-CELLULOLYTICUM; CRYSTAL-STRUCTURE; FORCE-FIELDS; CELLULOSE; DYNAMICS; CHARMM; THERMOCELLUM; PROTEINS; PROGRAM; COMPLEX AB Molecular dynamics simulations were used to study the possible catalytic role of an unusual conserved water-filled pore structure in the family 48 cellulase enzyme Cel48A from Thermobifida fusca. It was hypothesized that this pore serves as the pathway for the water molecules consumed in the hydrolysis catalyzed by the enzyme to reach the active site in a continuous stream to participate in the processive reactions. Theoretical mutants of this enzyme were created in which all of the residues lining the pore were made hydrophobic, which had the effect in molecular dynamics simulations of emptying the pore of water molecules and preventing any from passing through the pore on the simulation time scale. Mutants with smaller numbers of substitutions of this nature, which could be created experimentally by site-directed mutagenesis, were also identified from simulations, and these proteins were subsequently produced in Escherichia coli, expressed and purified, but were found to not fold in a manner similar to the wild type protein, preventing the determination of the importance of the water pore for activity. It is possible that the presence of a small vacuum in the pore was responsible for the instability of the mutants. In addition, alternate pathways were observed in the simulations that would allow water molecules to reach the active site of the enzyme, suggesting that the hypothesis that the pore has functional significance might be incorrect.

TI Structure and Stability of Lithium Superoxide Clusters and Relevance to Li-O-2 Batteries SO JOURNAL OF PHYSICAL CHEMISTRY LETTERS LA English DT Article ID MOLECULAR-ORBITAL METHODS; AB-INITIO CALCULATIONS; METAL-AIR BATTERIES; OXYGEN REDUCTION; DISCHARGE PRODUCT; HIGH-CAPACITY; BASIS SETS; CATALYSTS; ELECTROLYTE; CHARGE AB The discharge mechanism of a Li-O-2 battery involves lithium superoxide (LiO2) radicals. In this Letter, we have performed high-level quantum chemical calculations (G4MP2) to investigate the structure and stability of LiO2 clusters. The clusters have planar ring-shaped structures, high spins, and are thermodynamically more stable than LiO2 dimer. The computed energy barrier for disproportionation of the larger clusters is also significantly higher than the corresponding barrier in the LiO2 dimer (1.0 eV vs 0.5 eV). This means that disproportionation rate should be much slower if the reaction involves LiO2 clusters other than the dimer. As a result, the clusters may survive long enough to be incorporated into the growing discharge product. These results are discussed in terms of recent experimental studies of the electronic structure and morphology of the discharge products in Li-air batteries.

TI Direct Electronic Property Imaging of a Nanocrystal-Based Photovoltaic Device by Electron Beam-Induced Current via Scanning Electron Microscopy SO JOURNAL OF PHYSICAL CHEMISTRY LETTERS LA English DT Article ID DOT SOLAR-CELLS; POLYMER; PERFORMANCE; COMPOSITES; DYNAMICS AB Scanning electron microscopy (SEM) electron beam-induced current (EBIC) studies were performed on the cross-section of a nanocrystal-based hybrid bulk heterojunction photovoltaic device. Using these techniques, the short circuit carrier collection efficiencies are mapped with a better than 100 nm resolution. Electronically deficient and proficient regions within the photoactive layer are determined. The results show that only a fraction of the CdSe nanorod:P3HT layer (P3HT = poly-3(hexylthiophene)) at the Al cathode interface shows primary collection of charged carriers, in which the photoactivity decreases exponentially away from the interface. The recombination losses of the photoactive layer away from this interface prove that the limiting factor of the device is the inability for electrons to percolate between nanoparticles; to alleviate this problem, an interparticle network that conducts the electrons from one nanorod to the next must be established. Furthermore, the EBIC technique applied to the nanocrystalline device used in this study is the first measurement of its kind and can be applied toward other similar architectures.

TI Understanding Trends in CO2 Adsorption in Metal-Organic Frameworks with Open-Metal Sites SO JOURNAL OF PHYSICAL CHEMISTRY LETTERS LA English DT Article ID CARBON-DIOXIDE CAPTURE; COORDINATION SITES; HYDROGEN STORAGE; SUBSTITUTION; SEPARATION AB Using van der Waals-corrected density functional theory and a local chemical bond analysis, we study and explain trends in the binding between CO2 and open-metal coordination sites within a series of two metal-organic frameworks (MOFs), BTT, and MOF-74 for Ca, Mg, and nine divalent transition-metal cations. We find that Ti and V result in the largest CO2 binding energies and show that for these cations the CO2 binding energies for both structure types are twice the value expected based on pure electrostatics. We associate this behavior with the specific electronic configuration of the divalent cations and symmetry of the metal coordination site upon CO2 binding, which result in empty antibonding orbitals between CO2 and the metal cation. We demonstrate that a chemical bond analysis and electrostatic considerations can be used to predict trends of CO2 binding affinities to MOFs with transition-metal cations.

TI DNA interrogation by the CRISPR RNA-guided endonuclease Cas9 SO NATURE LA English DT Article ID IMMUNE-SYSTEM; TARGETED MUTAGENESIS; GENE-EXPRESSION; SEED SEQUENCE; SPECIFICITY; ACTIVATION; MECHANISM; TRANSCRIPTION; RECOGNITION; PROKARYOTES AB The clustered regularly interspaced short palindromic repeats (CRISPR)-associated enzyme Cas9 is an RNA-guided endonuclease that uses RNA-DNA base-pairing to target foreign DNA in bacteria. Cas9-guide RNA complexes are also effective genome engineering agents in animals and plants. Here we use single-molecule and bulk biochemical experiments to determine how Cas9-RNA interrogates DNA to find specific cleavage sites. We show that both binding and cleavage of DNA by Cas9-RNA require recognition of a short trinucleotide protospacer adjacent motif (PAM). Non-target DNA binding affinity scales with PAM density, and sequences fully complementary to the guide RNA but lacking a nearby PAM are ignored by Cas9-RNA. Competition assays provide evidence that DNA strand separation and RNA-DNA heteroduplex formation initiate at the PAM and proceed directionally towards the distal end of the target sequence. Furthermore, PAM interactions trigger Cas9 catalytic activity. These results reveal how Cas9 uses PAM recognition to quickly identify potential target sites while scanning large DNA molecules, and to regulate scission of double-stranded DNA.

TI Coherent Bragg nanodiffraction at the hard X-ray Nanoprobe beamline SO PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY A-MATHEMATICAL PHYSICAL AND ENGINEERING SCIENCES LA English DT Article DE ptychography; Bragg nanodiffraction; nanofocused X-rays; coherence; Nanoprobe beamline ID DIFFRACTION; PTYCHOGRAPHY; MICROSCOPY; RESOLUTION; CRYSTALS AB Bragg coherent diffraction with nanofocused hard X-ray beams provides unique opportunities for quantitative in situ studies of crystalline structure in nanoscale regions of complex materials and devices by a variety of diffraction-based techniques. In the case of coherent diffraction imaging, a major experimental challenge in using nanoscale coherent beams is maintaining a constant scattering volume such that coherent fringe visibility is maximized and maintained over the course of an exposure lasting several seconds. Here, we present coherent Bragg diffraction patterns measured from different nanostructured thin films at the Sector 26 Nanoprobe beamline at the Advanced Photon Source and demonstrate that with nanoscale positional control, coherent diffraction patterns can be measured with source-limited fringe visibilities more than 50% suitable for imaging by coherent Bragg ptychography techniques.

The method overcomes limitations in the level of sensitivity that can be achieved with the well-known Talbot grating interferometer, and without the stringent spectral filtering at any given incident angle imposed by the classic Bonse-Hart interferometer. The device operates in the far-field regime, where an incident beam is split by a diffraction grating into two widely separated beams, which are redirected by a second diffraction grating to merge at a third grating, where they coherently interfere. The wide separation of the interfering beams results in large phase contrast, and in some cases absolute phase images are obtained. Imaging experiments were performed using diffraction gratings of 200 nm period, at 22.5 keV and 1.5% spectral bandwidth on a bending-magnetic beamline. Novel design and fabrication process were used to achieve the small grating period. Using a slitted incident beam, we acquired absolute and differential phase images of lightly absorbing samples. An advantage of this method is that it uses only phase modulating gratings, which are easier to fabricate than absorption gratings of the same periods.

TI Ancient pathogen DNA in archaeological samples detected with a Microbial Detection Array SO SCIENTIFIC REPORTS LA English DT Article ID YERSINIA-PESTIS; GENOME; SEQUENCES; ALIGNMENT; INSIGHTS AB Ancient human remains of paleopathological interest typically contain highly degraded DNA in which pathogenic taxa are often minority components, making sequence-based metagenomic characterization costly. Microarrays may hold a potential solution to these challenges, offering a rapid, affordable, and highly informative snapshot of microbial diversity in complex samples without the lengthy analysis and/or high cost associated with high-throughput sequencing. Their versatility is well established for modern clinical specimens, but they have yet to be applied to ancient remains. Here we report bacterial profiles of archaeological and historical human remains using the Lawrence Livermore Microbial Detection Array (LLMDA). The array successfully identified previously-verified bacterial human pathogens, including Vibrio cholerae (cholera) in a 19th century intestinal specimen and Yersinia pestis ("Black Death" plague) in a medieval tooth, which represented only minute fractions (0.03% and 0.08% alignable high-throughput shotgun sequencing reads) of their respective DNA content. This demonstrates that the LLMDA can identify primary and/or co-infecting bacterial pathogens in ancient samples, thereby serving as a rapid and inexpensive paleopathological screening tool to study health across both space and time.

CA CMS Collaboration TI Study of double parton scattering using W+2-jet events in proton-proton collisions at root s=7 TeV SO JOURNAL OF HIGH ENERGY PHYSICS LA English DT Article DE Jet physics; Hadron-Hadron Scattering; QCD ID 4-JET EVENTS; HADRON-COLLISIONS; COLLIDER; LHC AB Double parton scattering is investigated in proton-proton collisions at = 7 TeV where the final state includes a W boson, which decays into a muon and a neutrino, and two jets. The data sample corresponds to an integrated luminosity of 5 fb(-1), collected with the CMS detector at the LHC. Observables sensitive to double parton scattering are investigated after being corrected for detector effects and selection efficiencies. The fraction of W + 2-jet events due to double parton scattering is measured to be 0.055 +/- 0.002 (stat.) +/- 0.014 (syst.). The effective cross section, sigma (eff), characterizing the effective transverse area of hard partonic interactions in collisions between protons is measured to be 20.7 +/- 0.8(stat.) +/- 6.6(syst.)mb.

TI Evidence for the decay B-0 -> omega omega and search for B-0 -> omega phi SO PHYSICAL REVIEW D LA English DT Article ID BABAR DETECTOR; CP-ASYMMETRIES; POLARIZATION; SUPERSYMMETRY AB We describe searches for B meson decays to the charmless vector-vector final states omega omega and omega phi with 471 x 10(6) B (B) over bar pairs produced in e(+)e(-) annihilation at root s = 10.58 GeV using the BABAR detector at the PEP-II collider at the SLAC National Accelerator Laboratory. We measure the branching fraction B(B-0 -> omega omega) = (1.2 +/- 0.3(-0.2)(+0.3)) x 10(-6), where the first uncertainty is statistical and the second is systematic, corresponding to a significance of 4.4 standard deviations. We also determine the upper limit B(B-0 -> omega phi) < 0.7 x 10(-6) at 90% confidence level. These measurements provide the first evidence for the decay B-0 -> omega omega, and an improvement of the upper limit for the decay B-0 -> omega phi. C1 [Lees, J.

CA ATLAS Collaboration TI Search for Quantum Black Hole Production in High-Invariant-Mass Lepton plus Jet Final States Using pp Collisions at root s=8 TeV and the ATLAS Detector SO PHYSICAL REVIEW LETTERS LA English DT Article ID PROTON-PROTON COLLISIONS; CARLO EVENT GENERATOR; DIMENSIONS; MILLIMETER; LHC AB This Letter presents a search for quantum black-hole production using 20.3 fb(-1) of data collected with the ATLAS detector in pp collisions at the LHC at root s = 8 TeV. The quantum black holes are assumed to decay into a final state characterized by a lepton (electron or muon) and a jet. In either channel, no event with a lepton-jet invariant mass of 3.5 TeV or more is observed, consistent with the expected background. Limits are set on the product of cross sections and branching fractions for the lepton + jet final states of quantum black holes produced in a search region for invariant masses above 1 TeV. The combined 95% confidence level upper limit on this product for quantum black holes with threshold mass above 3.5 TeV is 0.18 fb. This limit constrains the threshold quantum black-hole mass to be above 5.3 TeV in the model considered. C1 [Conventi, F.; Jackson, P.; Soni, N.; White, M.

The degradation behavior of a series of DPAHs, designed for lanthanide/actinide separation, was examined. The stability of the DPAHs, when contacted with varying nitric acid concentrations, was tested and monitored using P-31 {H-1} NMR Changes in the functional groups of the DPAHs resulted in substantial increases in the stability. However, when placed in contact with 2 M HNO3 all the DPAHs eventually showed signs of degradation. The addition of a radical scavenger, hydrazine, inhibited the degradation of the DPAHs. In the presence of a small concentration of hydrazine, five of the DPAHs remained stable for over a month in direct contact with 2 M HNO3.

SO INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH LA English DT Article ID SOLUBILIZING METAL-OXIDES; HETEROCYCLIC N-DONORS; RARE-EARTH IONS; SOLVENT-EXTRACTION; TALSPEAK PROCESS; F-ELEMENTS; TEMPERATURE; COMPLEXES; CHEMISTRY; NEODYMIUM(III) AB Group separations of lanthanides from minor actinides is required in the currently considered scenarios for closing of the nuclear fuel cycle. TALSPEAK is a well-known and historically first process suggested for such separations. The process is based on competitive complexation of trivalent f-group ions by an aminopolycarboxylate (such as the base of diethylenetriamine-N,N,N',N '',N ''-pentaacetic acid, DTPA) in an aqueous buffer and a dialkylphosphate (such as the base of bis(2-ethylhexyl)phosphoric acid, HDEHP) in an organic phase. Unfortunately, this method exhibits excessive sensitivity to pH and composition of the aqueous feed. In this study, we "reinvent" TALSPEAK, retaining the competitive ion binding but changing considerably the chemical implementation of the underlying general principles. The DTPA moiety is integrated into a functionalized ionic liquid (IL) that is immiscible with an organic phase containing dialkylphosphate ligands. Choline and betainium bistriflimides double as IL diluents and synthetic reagents. The integration of the aminopolycarboxylate moiety into these ILs is achieved in situ through the reactions of the cyclical dianhydride of DTPA with IL functional groups, either through the formation of a mixed dianhydride (for the betainium cation) or a diester (for the choline cation). The deprotonated DTPA-betainium conjugate forms 1:1 complexes with trivalent f-element cations whereas these metal ions form 1:2 complexes with the DTPA-choline conjugates. Large separation factors for Eu/Am partitioning between the two phases are observed, approaching 120-150 for DTPA-betainium and 250-270 for DTPA-choline. In the latter system, as in the traditional aqueous TALSPEAK, there is a characteristic "parabolic" dependence of the phase distribution ratios as a function of ionic radius that allows separations of the largest lanthanide ions. Group separations of all lanthanides from americium has been demonstrated, and a separation process that is based on this chemistry is suggested.

We show, for the first time, that an analogue of the iconic M-2(2,5-dioxidoterephthalate) (M2DOBDC, MOF-74) class of materials can be stoichiometrically oxidized by one electron per metal center. The reaction of Mn2DOBDC with C6H5ICI2 produces the oxidized material Cl2Mn2DOBDC, which retains crystallinity and porosity. Surprisingly, magnetic measurements, X-ray absorption, and infrared spectroscopic data indicate that the Mn ions maintain a formal oxidation state of +2, suggesting instead the oxidation of the DOBDC4- ligand to the quinone DOBDC2-. These results describe the first example of ligand redox non-innocence in a MOF and a rare instance of stoichiometric electron transfer involving the metal nodes. The methods described herein offer a synthetic toolkit that will be of general use for further explorations of the redox reactivity of MOF nodes.

TI Unravelling the Mechanism of the Asymmetric Hydrogenation of Acetophenone by [RuX2(diphosphine)(1,2-diamine)] Catalysts SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID ENANTIOSELECTIVE KETONE HYDROGENATION; LIGAND BIFUNCTIONAL ADDITION; STEREOSELECTIVE HYDROGENATION; PROTON-TRANSFER; ORGANOMETALLIC CHEMISTRY; RUTHENIUM CATALYSTS; FREE-ENERGY; BINAP/1,2-DIAMINE-RUTHENIUM(II) COMPLEXES; HOMOGENEOUS HYDROGENATION; SELECTIVE HYDROGENATION AB The mechanism of catalytic hydrogenation of acetophenone by the chiral complex trans-[RuCl2{(S)-binap}{(S,S)-dpen}] and KO-t-C4H9 in propan-2-ol is revised on the basis of OFT computations carried out in dielectric continuum and the most recent experimental observations. The results of these collective studies suggest that neither a six-membered pericyclic transition state nor any multibond concerted transition states are involved. Instead, a hydride moiety is transferred in an outer-sphere manner to afford an ion-pair, and the corresponding transition state is both enantio- and rate-determining. Heterolytic dihydrogen cleavage proceeds neither by a (two-bond) concerted, four-membered transition state, nor by a (three-bond) concerted, six-membered transition state mediated by a solvent molecule. Instead, cleavage of the H-H bond is achieved via deprotonation of the eta(2)-H-2 ligand within a cationic Ru complex by the chiral conjugate base of (R)-1-phenylethanol. Thus, protonation of the generated (R)-1-phenylethoxide anion originates from the eta(2)-H-2 ligand of the cationic Ru complex and not from NH protons of a neutral Ru trans-dihydride complex, as initially suggested within the framework of a metal-ligand bifunctional mechanism. Detailed computational analysis reveals that the 16e(-) Ru amido complex [RuH{(S)-binap}{(S,S)-HN-(CHPh)(2)NH2}] and the 18e(-) Ru alkoxo complex trans-[RuH{OCH(CH3)(R)}{(S)-binap}{(S,S)-dpen}] (R = CH3 or C6H5) are not intermediates within the catalytic cycle, but rather are off-loop species. The accelerative effect of KO-t-C4H9 is explained by the reversible formation of the potassium amidato complexes trans-[RuH2{(S)-binap}{(S,S)-N(K)H-(CHPh)(2)NH2}] or trans-[RuH2{(S)-binap}{(S,S)-N(K)H(CHPh)(2)NH(K)}]. The three-dimensional (3D) cavity observed within these molecules results in a chiral pocket stabilized via several different noncovalent interactions, including neutral and ionic hydrogen bonding, cation-pi interactions, and it pi-pi stacking interactions. Cooperatively, these interactions modify the catalyst structure, in turn lowering the relative activation barrier of hydride transfer by similar to 1-2 kcal mol(-1) and the following H-H bond cleavage by similar to 10 kcal mol(-1), respectively. A combined computational study and analysis of recent experimental data of the reaction pool results in new mechanistic insight into the catalytic cycle for hydrogenation of acetophenone by Noyori's catalyst, in the presence or absence of KO-t-C4H9.

Time-resolved IR spectroscopic measurements revealed efficient hydrogen atom transfer from xanthene, 9,10-dihydroanthracene, and 1,4-cyclohexadiene to Cp(CO)(2)Os-center dot and (eta(5)-(Pr4C5H)-Pr-i)(CO)(2)Os-center dot radicals, formed by photoinduced homolysis of the corresponding osmium dimers. The rate constants for hydrogen abstraction from these hydrocarbons are in the range 1.5 X 10(5) M-1 s(-1) to 1.7 X 10(7) M-1 s(-1) at 25 degrees C. For the first time, kinetic isotope effects for carbon-to-metal hydrogen atom transfer were determined. Large primary deuterium kinetic isotope effects of 13.4 +/- 1.0 and 16.8 +/- 1.4 were observed for the hydrogen abstraction from xanthene to form Cp(CO)(2)OsH and (eta(5)-(Pr4C5H)-Pr-i)(CO)(2)OsH, respectively, at 25 degrees C. Temperature-dependent measurements of the kinetic isotope effects over a 60 degrees C temperature range were carried out to obtain the difference in activation energies (E-D - E-H) and the pre-exponential factor ratio (A(H)/A(D)). For hydrogen atom transfer from xanthene to (eta(5)-(Pr4C5H)-Pr-i)(CO)(2)Os-center dot, the (E-D - E-H) = 3.3 +/- 0.2 kcal mol(-1) and A(H)/A(D) = 0.06 +/- 0.02 values suggest a quantum mechanical tunneling mechanism.

The spectra show well-resolved peaks and complex spectral patterns. The electron affinity of MBQ is determined from the first resolved peak to be 2.875 +/- 0.010 eV. Single-point, CASPT2/aug-cc-pVTZ//CASPT2/aug-cc-pVDZ calculations predict accurately the positions of the 0-0 bands in the NIPE spectrum for formation of the four lowest electronic states of neutral MBQ from the (2)A(2) state of MBQ(center dot-). In addition, the Franck-Condon factors that are computed from the CASPT2/aug-cc-pVDZ optimized geometries, vibrational frequencies, and normal mode vectors, successfully simulate the intensities and frequencies of the vibrational peaks in the NIPE spectrum that are associated with each of these electronic states. The successful simulation of the NIPE spectrum of MBQ(center dot-) allows the assignment of B-3(2) as the ground state of MBQ, followed by the B-1(2) and (1)A(1) electronic states, respectively 9.0 +/- 0.2 and 16.6 +/- 0.2 kcal/mol higher in energy than the triplet. These experimental energy differences are in good agreement with the calculated values of 9.7 and 15.7 kcal/mol. The relative energies of these two singlet states in MBQ confirm the previous prediction that their relative energies would be reversed from those in meta-benzoquinodimethane (MBQDM, m-CH2C6H4CH2) C1 [Chen, Bo; Hrovat, David A.; Borden, Weston Thatcher] Univ N Texas, Dept Chem, Denton, TX 76203 USA.

TI In Situ IR and X-ray High Spatial-Resolution Microspectroscopy Measurements of Multistep Organic Transformation in Flow Microreactor Catalyzed by Au Nanoclusters SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID HETEROGENEOUS CATALYSIS; METALLIC NANOPARTICLES; CHEMICAL-SYNTHESIS; RESIDENCE-TIME; SPECTROSCOPY; REACTOR; HYDROGENATION; SELECTIVITY; CHEMISTRY; OXIDATION AB Analysis of catalytic organic transformations in flow reactors and detection of short-lived intermediates are essential for optimization of these complex reactions. In this study, spectral mapping of a multistep catalytic reaction in a flow microreactor was performed with a spatial resolution of 15 mu m, employing micrometer-sized synchrotron-based IR and X-ray beams. Two nanometer sized Au nanoclusters were supported on mesoporous SiO2, packed in a flow microreactor, and activated toward the cascade reaction of pyran formation. High catalytic conversion and tunable products selectivity were achieved under continuous flow conditions. In situ synchrotron-sourced IR microspectroscopy detected the evolution of the reactant, vinyl ether, into the primary product, allenic aldehyde, which then catalytically transformed into acetal, the secondary product. By tuning the residence time of the reactants in a flow microreactor a detailed analysis of the reaction kinetics was performed. An in situ micrometer X-ray absorption spectroscopy scan along the flow reactor correlated locally enhanced catalytic conversion, as detected by IR microspectroscopy, to areas with high concentration of Au(III), the catalytically active species. These results demonstrate the fundamental understanding of the mechanism of catalytic reactions which can be achieved by the detailed mapping of organic transformations in flow reactors C1 [Gross, Elad; Shu, Xing-Zhong; Alayoglu, Selim; Toste, F.

Complexes incorporating the binucleating ligand N[o-((NHCH2PPr2)-Pr-i)C6H4](3) with either Th(IV) (4) or U(IV) (5) and a carbonyl bridged [Co(CO)(4)](-) unit were synthesized from the corresponding actinide chlorides (Th: 2; U: 3) and Na[Co(CO)(4)]. Irradiation of the resulting isocarbonyls with ultraviolet light resulted in the formation of new species containing actinide-metal bonds in good yields (Th: 6; U: 7); this photolysis method provides a new approach to a relatively unusual class of complexes. Characterization by single-crystal X-ray diffraction revealed that elimination of the bridging carbonyl and formation of the metal-metal bond is accompanied by coordination of a phosphine arm from the N4P3 ligand to the cobalt center. Additionally, actinide-cobalt bonds of 3.0771(5) angstrom and 3.0319(7) angstrom for the thorium and uranium complexes, respectively, were observed. The solution-state behavior of the thorium complexes was evaluated using H-1, H-1-H-1 COSY, (31)p, and variable-temperature NMR spectroscopy. IR, UV-vis/NIR, and variable-temperature magnetic susceptibility measurements are also reported. C1 [Ward, Ashleigh L.; Arnold, John] Univ Calif Berkeley, Dept Chem, Berkeley, CA 94720 USA.

TI Polymorphism, phase transitions, and thermal expansion of K3Lu(PO4)(2) SO JOURNAL OF ALLOYS AND COMPOUNDS LA English DT Article DE Crystal structure; Powder neutron diffraction; Phase transitions; Phosphate; Scintillator; Single-crystal X-ray diffraction ID DOUBLE-PHOSPHATE SCINTILLATORS; LUMINESCENCE PROPERTIES; VUV SCINTILLATION; EARTH; THERMOCHEMISTRY; ORTHOPHOSPHATES; LUPO4-ND AB Alkali rare-earth double phosphates have been studied for use as long-wavelength scintillators for gamma-ray detection using Si photodiodes. Single-crystal and powder X-ray diffraction (XRD) and powder neutron diffraction have been used to study the structure as a function of temperature. K3Lu(PO4)(2) crystallizes with a hexagonal unit cell at room temperature, space group P (3) over bar. The Lu ion is six-coordinated to the oxygen atoms of the phosphate groups. Two lower-temperature phases were characterized using single-crystal XRD and powder neutron diffraction. The first transition occurs at 230 K with a transformation to a monoclinic P2(1)/m space group symmetry, and the Lu retains six coordination. The second phase transition occurs at 130 K, with a large change in the cell volume, keeping the same P2(1)/m space group symmetry; however, one of the phosphate groups rotates to increase the coordination of the Lu ion to seven. This is an unusual example of an isosymmetric phase transition with a coordination change, driven by temperature. High-temperature powder neutron diffraction and high-temperature powder XRD have been used to study the thermal expansion of K3Lu(PO4)(2) and indicate a large thermal expansion anisotropy. The crystallographic axes with largest changes account for the structural collapse, which rotates the phosphate group to increase the Lu coordination. The lowest temperature form of K3Lu(PO4)(2) is the same as the room temperature form for all the lighter RE compounds of the same type, which is not surprising, given the lighter (larger) RE ions would prefer a higher coordination number.

The results show that a pressure-induced structural transition from the cubic to the rhombohedral phase occurs at 23.5 GPa. The calculated structural and magnetic properties of the rhombohedral phase suggest that an isostructural transition occurs at 22.5 GPa. The low-pressure rhombohedral phase has a fcc-like structure. We predict that under further compression, an antiferromagnetic to nonmagnetic transition occurs. This phase transition has been not observed by experiment yet. To evaluate conditions under which other new phase transitions might occur, we studied the phase stability of UN at finite temperature by taking into account the lattice vibrational and thermal electronic contributions to Gibbs energy. Based on the Gibbs energy models, the pressure-temperature phase diagram of UN was studied and the phase boundaries of the antiferromagnetic rhombohedral phase were also determined. We predict that, although metastable, the antiferromagnetic rhombohedral phase might be stabilized at low-temperature by quenching from the high-pressure phase. (C) 2013 Elsevier B. V.

In the present study, a skeletal mechanism for n-dodecane with 105 species and 420 reactions was developed for spray combustion simulations. The reduction starts from the most recent detailed mechanism for n-alkanes consisting of 2755 species and 11,173 reactions developed by the Lawrence Livermore National Laboratory. An algorithm combining direct relation graph with expert knowledge (DRGX) and sensitivity analysis was employed for the present skeletal reduction. The skeletal mechanism was first extensively validated in 0-D and 1-D combustion systems, including auto-ignition, jet stirred reactor (JSR), laminar premixed flame and counter flow diffusion flame. Then it was coupled with well-established spray models and further validated in 3-D turbulent spray combustion simulations under engine-like conditions. These simulations were compared with the recent experiments with n-dodecane as a surrogate for diesel fuels. It can be seen that combustion characteristics such as ignition delay and flame lift-off length were well captured by the skeletal mechanism, particularly under conditions with high ambient temperatures. Simulations also captured the transient flame development phenomenon fairly well. The results further show that ignition delay may not be the only factor controlling the stabilisation of the present flames since a good match in ignition delay does not necessarily result in improved flame lift-off length prediction.

DSD provides an efficient method for studying detonation front propagation in such materials without the necessity of simulating the combustion equations for the entire system. We derive a series of partial differential equations in a cylindrical coordinate system and a moving shock-attached coordinate system which describes the propagation of detonation about a single particle, where the detonation obeys a linear shock normal velocity-curvature (D-n-kappa) DSD relation. We solve these equations numerically and observe the short-term and long-term behaviour of the detonation shock wave as it passes over the particles. We discuss the shape of the perturbed shock wave and demonstrate the periodic and convergent behaviour obtained when detonation passes over a regular, periodic array of inert spherical particles.

The products of these reactions were identified as: [(OR)(2)Ti(mu-(c,c-OBzA))](2) (OR = OCHMe2 (OPri; 1 center dot 2tol); OCMe3 (OBut; 2 center dot THF); OCH2CMe3 (ONep; 3)), [[(OPri)(3)Ti(mu-OPri)Ti(OPri)(2)](2)(mu-(mu(c),mu-OBzA))(2)](2) (4), [(ONep)(3)Zr(mu-ONep)(2)Zr(ONep)(2)](2)(mu-(c,mu-OBzA)(2)) (5 center dot tol), [(py)(OBut)(3)Zr](2)(mu-(c,c-OBzA)) (6), [(OBut)(2)Hf(mu-OBut)](2)(mu-(c,eta(1)-OBzA)) (7) where 'c' = chelating or eta(2); 'mu' = bridging or eta(1),eta(1)(O,O'); and mu(c) = bridging chelating or eta(1),eta(1)(O,O'); eta(2 ): eta(1). The metal centers for each of these compounds adopt a pseudo-octahedral geometry employing the OBzA ligand in numerous binding modes. The different functional oxygens (carboxylate, hydroxyl, and carbonyl) were employed in a variety of coordination modes for 1-7. The complexity of these OBzA-modified compounds is driven by a combination of the coordination behavior of the OBzA moieties, the size of the metal cation, and the pendant chain of the OR ligand. Solution NMR indicates a complex structure exists in solution that was considered to be consistent with the solid-state structure.

One activity associated with declines in freshwater fish populations is water resource development, including dams, weirs, and hydropower facilities. Fish passing through irrigation and hydro infrastructures during downstream migration experience a rapid decrease in pressure, which can lead to injuries (barotrauma) that contribute to mortality. There is renewed initiative to expand hydropower and irrigation infrastructure to improve water security and increase low-carbon energy generation. The impact of barotrauma on fish must be understood and mitigated to ensure that development is sustainable for fisheries. This will involve taking steps to expand the knowledge of barotrauma-related injury from its current focus, mainly on seaward-migrating juvenile salmonids of the Pacific Northwest, to incorporate a greater diversity of fish species and life stages from many parts of the world. This article summarizes research that has examined barotrauma during fish passage and articulates a research framework to promote a standardized, global approach. The suggested approach provides clearly defined links to adaptive development of fish friendly technologies, aimed at mitigating the threats faced by global freshwater fisheries from the rapid expansion of water infrastructure.

These are produced as part of the Inter-Sectoral Impacts Model Intercomparison Project, with coordination from the Agricultural Model Intercomparison and Improvement Project, and driven by outputs of general circulation models run under representative concentration pathway 8.5 as part of the Fifth Coupled Model Intercomparison Project. Models project that direct climate impacts to maize, soybean, wheat, and rice involve losses of 4001,400 Pcal (8-24% of present-day total) when CO2 fertilization effects are accounted for or 1,400-2,600 Pcal (24-43%) otherwise. Freshwater limitations in some irrigated regions (western United States; China; and West, South, and Central Asia) could necessitate the reversion of 20-60 Mha of cropland from irrigated to rainfed management by end-of-century, and a further loss of 600-2,900 Pcal of food production. In other regions (northern/eastern United States, parts of South America, much of Europe, and South East Asia) surplus water supply could in principle support a net increase in irrigation, although substantial investments in irrigation infrastructure would be required.

Plausible estimates of these climate change impacts require combined use of climate, crop, and economic models. Results from previous studies vary substantially due to differences in models, scenarios, and data. This paper is part of a collective effort to systematically integrate these three types of models. We focus on the economic component of the assessment, investigating how nine global economic models of agriculture represent endogenous responses to seven standardized climate change scenarios produced by two climate and five crop models. These responses include adjustments in yields, area, consumption, and international trade. We apply biophysical shocks derived from the Intergovernmental Panel on Climate Change's representative concentration pathway with end-of-century radiative forcing of 8.5 W/m(2). The mean biophysical yield effect with no incremental CO2 fertilization is a 17% reduction globally by 2050 relative to a scenario with unchanging climate. Endogenous economic responses reduce yield loss to 11%, increase area of major crops by 11%, and reduce consumption by 3%. Agricultural production, crop-land area, trade, and prices show the greatest degree of variability in response to climate change, and consumption the lowest. The sources of these differences include model structure and specification; in particular, model assumptions about ease of land use conversion, intensification, and trade. This study identifies where models disagree on the relative responses to climate shocks and highlights research activities needed to improve the representation of agricultural adaptation responses to climate change.

However, in situ probing of grain boundary processes of ultrafine nanocrystals during plastic deformation has not been feasible, precluding the direct exploration of the nanomechanics. Here we present the in situ texturing observation of bulk-sized platinum in a nickel pressure medium of various particle sizes from 500 nm down to 3 nm. Surprisingly, the texture strength of the same-sized platinum drops rapidly with decreasing grain size of the nickel medium, indicating that more active grain rotation occurs in the smaller nickel nanocrystals. Insight into these processes provides a better understanding of the plastic deformation of nanomaterials in a few-nanometer length scale.

Here, we use a single-molecule transcription elongation assay to study the effects of both factors. We find that these transcription factors enhance overall transcription elongation by reducing the lifetime of transcriptional pauses and that TFIIF also decreases the probability of pause entry. Furthermore, we observe that both factors enhance the processivity of RNA polymerase II through the nucleosomal barrier. The effects of TFIIS and TFIIF are quantitatively described using the linear Brownian ratchet kinetic model for transcription elongation and the backtracking model for transcriptional pauses, modified to account for the effects of the transcription factors. Our findings help elucidate the molecular mechanisms by which transcription factors modulate gene expression.

TI Stochasticity, succession, and environmental perturbations in a fluidic ecosystem SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE community assembly; disturbances; metagenomics; GeoChip; remediation ID HIGHLY CONTAMINATED AQUIFER; IN-SITU BIOREMEDIATION; NULL MODEL ANALYSIS; SEA OIL PLUME; MICROBIAL COMMUNITIES; CARBON SEQUESTRATION; DIVERSITY; DISTURBANCE; ECOLOGY; URANIUM AB Unraveling the drivers of community structure and succession in response to environmental change is a central goal in ecology. Although the mechanisms shaping community structure have been intensively examined, those controlling ecological succession remain elusive. To understand the relative importance of stochastic and deterministic processes in mediating microbial community succession, a unique framework composed of four different cases was developed for fluidic and nonfluidic ecosystems. The framework was then tested for one fluidic ecosystem: a groundwater system perturbed by adding emulsified vegetable oil (EVO) for uranium immobilization. Our results revealed that groundwater microbial community diverged substantially away from the initial community after EVO amendment and eventually converged to a new community state, which was closely clustered with its initial state. However, their composition and structure were significantly different from each other. Null model analysis indicated that both deterministic and stochastic processes played important roles in controlling the assembly and succession of the groundwater microbial community, but their relative importance was time dependent. Additionally, consistent with the proposed conceptual framework but contradictory to conventional wisdom, the community succession responding to EVO amendment was primarily controlled by stochastic rather than deterministic processes. During the middle phase of the succession, the roles of stochastic processes in controlling community composition increased substantially, ranging from 81.3% to 92.0%. Finally, there are limited successional studies available to support different cases in the conceptual framework, but further well-replicated explicit time-series experiments are needed to understand the relative importance of deterministic and stochastic processes in controlling community succession.

The molecular basis of this extremophile phenotype, involving strain isolates with a 3-4 order of magnitude increase in IR resistance at 3000 Gy, is now addressed. Of 69 mutations identified in one of our most highly adapted isolates, functional experiments demonstrate that the IR resistance phenotype is almost entirely accounted for by only three of these nucleotide changes, in the DNA metabolism genes recA, dnaB, and yfjK. Four additional genetic changes make small but measurable innovations involving pre-existing DNA repair functions can play a predominant role in the acquisition of an IR resistance phenotype.

Zuberi, Saba TI Jet p(T) resummation in Higgs production at NNLL ' plus NNLO SO PHYSICAL REVIEW D LA English DT Article ID HADRON-HADRON COLLISIONS; BOSON PRODUCTION; CROSS-SECTIONS; QCD; ALGORITHM; LHC AB We present predictions for Higgs production via gluon fusion with a p(T) veto on jets and with the resummation of jet-veto logarithms at NNLL' + NNLO order. These results incorporate explicit O(alpha(2)(s)) calculations of soft and beam functions, which include the dominant dependence on the jet radius R. In particular the NNLL' order accounts for the correct boundary conditions for the (NLL)-L-3 resummation, for which the only unknown ingredients are higher-order anomalous dimensions. We use scale variations in a factorization theorem in both rapidity and virtuality space to estimate the perturbative uncertainties, accounting for both higher fixed-order corrections as well as higher-order towers of jet-p(T) logarithms. This formalism also predicts the correlations in the theory uncertainty between the exclusive 0-jet and inclusive 1-jet bins. At the values of R used experimentally, there are important corrections due to jet algorithm clustering that include logarithms of R. Although we do not sum logarithms of R, we do include an explicit contribution in our uncertainty estimate to account for higher-order jet clustering logarithms. Precision predictions for this H + 0-jet cross section and its theoretical uncertainty are an integral part of Higgs analyses that employ jet binning.

CA LUX Collaboration TI First Results from the LUX Dark Matter Experiment at the Sanford Underground Research Facility SO PHYSICAL REVIEW LETTERS LA English DT Article ID LARGE-SCALE STRUCTURE; SEARCH; XENON; CANDIDATES AB The Large Underground Xenon (LUX) experiment is a dual-phase xenon time-projection chamber operating at the Sanford Underground Research Facility (Lead, South Dakota). The LUX cryostat was filled for the first time in the underground laboratory in February 2013. We report results of the first WIMP search data set, taken during the period from April to August 2013, presenting the analysis of 85.3 live days of data with a fiducial volume of 118 kg. A profile-likelihood analysis technique shows our data to be consistent with the background-only hypothesis, allowing 90% confidence limits to be set on spin-independent WIMP-nucleon elastic scattering with a minimum upper limit on the cross section of 7.6 x 10(-46) cm(2) at a WIMP mass of 33 GeV= c(2). We find that the LUX data are in disagreement with low-mass WIMP signal interpretations of the results from several recent direct detection experiments. C1 [Chan, C.; Chapman, J.

CA CAST Collaboration TI Search for Solar Axions by the CERN Axion Solar Telescope with He-3 Buffer Gas: Closing the Hot Dark Matter Gap SO PHYSICAL REVIEW LETTERS LA English DT Article ID COHERENT CONVERSION; CAST EXPERIMENT; MAGNETIC-FIELD; CP INVARIANCE; DETECTORS; PHOTONS; MASS AB The CERN Axion Solar Telescope has finished its search for solar axions with He-3 buffer gas, covering the search range 0.64 eV less than or similar to ma less than or similar to 1.17 eV. This closes the gap to the cosmological hot dark matter limit and actually overlaps with it. From the absence of excess x rays when the magnet was pointing to the Sun we set a typical upper limit on the axion-photon coupling of g(a gamma) less than or similar to 3.3 x 10(-10) GeV-1 at 95% C.L., with the exact value depending on the pressure setting. Future direct solar axion searches will focus on increasing the sensitivity to smaller values of g(a gamma), for example by the currently discussed next generation helioscope International AXion Observatory.

TI Blurring the Boundaries: Decays of Multiparticle Isomers at the Proton Drip Line SO PHYSICAL REVIEW LETTERS LA English DT Article ID TOTAL DATA READOUT; GREAT SPECTROMETER; ATOMIC-NUCLEI; YRAST STATES; RADIOACTIVITY; SPECTROSCOPY; SEPARATOR; (CO-53)M AB A multiparticle spin-trap isomer has been discovered in the proton-unbound nucleus 158 73 Ta 85. The isomer mainly decays by (h) over bar -ray emission with a half-life of 6.1d(1) mu s. Analysis of the gamma-ray data shows that the isomer lies 2668 keV above the known 9(+) state and has a spin 10h higher and negative parity. This 19(-) isomer also has an 8644(11) keV, 1.4(2)% alpha-decay branch that populates the 9(+) state in Lu-154. No proton-decay branch from the isomer was identified, despite the isomer being unbound to proton emission by 3261(14) keV. This remarkable stability against proton emission is compared with theoretical predictions, and the implications for the extent of observable nuclides are considered. C1 [Carroll, R. J.; Page, R.

The magnetic exchange coupling is, however, very sensitive to a local mode involving transverse displacements of O and Fe, resulting in zigzag patterns of distortion. The buckling driven by rising temperatures is enhanced just as the Fe magnetic moment is reduced, implying a strong spin-lattice coupling. It is suggested that the undulations lead to orbital disorder by distorting the three possible paths to exchange interactions.

TI Inverse Modeling of Water-Rock-CO2 Batch Experiments: Potential Impacts on Groundwater Resources at Carbon Sequestration Sites SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID NATURAL ANALOG SITE; CO2 SEQUESTRATION; TRANSPORT MODELS; AQUIFERS; LEAKAGE; FIELD; BENTONITE; CHEMISTRY; PHASE AB This study developed a multicomponent geo-chemical model to interpret responses of water chemistry to introduction of CO2 into six water-rock batches with sedimentary samples collected from representative potable aquifers in the Gulf Coast area. The model simulated CO2 dissolution in groundwater, aqueous complexation, mineral reactions (dissolution/precipitation), and surface complexation on clay mineral surfaces. An inverse method was used to estimate mineral surface area, the key parameter for describing kinetic mineral reactions. Modeling results suggested that reductions in groundwater pH were more significant in the carbonate-poor aquifers than in the carbonate-rich aquifers, resulting in potential groundwater acidification. Modeled concentrations of major ions showed overall increasing trends, depending on mineralogy of the sediments, especially carbonate content. The geochemical model confirmed that mobilization of trace metals was caused likely by mineral dissolution and surface complexation on clay mineral surfaces. Although dissolved inorganic carbon and pH may be used as indicative parameters in potable aquifers, selection of geochemical parameters for CO2 leakage detection is site-specific and a stepwise procedure may be followed. A combined study of the geochemical models with the laboratory batch experiments improves our understanding of the mechanisms that dominate responses of water chemistry to CO2 leakage and also provides a frame of reference for designing monitoring strategy in potable aquifers.

Here, we functionalized CVD-grown graphene and graphene oxide with a genetically engineered elastin-like polypeptide fused to a graphene binding peptide and then showed that the resulting hybrid materials exhibit thermo-and photoresponsive behaviors. Furthermore, we demonstrate that our genetic engineering strategy allows for the facile introduction of bioactivity to reduced graphene oxide. The stimuli-responsiveness and genetic tunability of our graphene-protein nanocomposites are attractive for addressing future biomedical applications.

Here we have developed a functional gene-based microarray for profiling human microbiomes (HuMiChip) with 36,802 probes targeting 50,007 protein coding sequences for 139 key functional gene families. Computational evaluation suggested all probes included are highly specific to their target sequences. HuMiChip was used to analyze human oral and gut microbiomes, showing significantly different functional gene profiles between oral and gut microbiome. Obvious shifts of microbial functional structure and composition were observed for both patients with dental caries and periodontitis from moderate to advanced stages, suggesting a progressive change of microbial communities in response to the diseases. Consistent gene family profiles were observed by both HuMiChip and next generation sequencing technologies. Additionally, HuMiChip was able to detect gene families at as low as 0.001% relative abundance. The results indicate that the developed HuMiChip is a useful and effective tool for functional profiling of human microbiomes.

Phonon anomalies in the TA(2) acoustic branch along the Gamma-M [xi,xi,0] direction associated with a structural transformation are observed. The calculated Fermi surface of the B2 phase of AuZn reveals large portions nested with each other by a translation through a vector q = 1/3[1,1,0] associated with the soft mode. In addition, we find that the B2 phase can be stabilized by pressure in the low-temperature limit. The energetic barrier for the B2 -> R transition is 2 mRy and appears to be near a critical point.

In general, very good agreement was found between theory and experiment for both phonon energies and line widths. Our analysis reveals that the strong coupling of certain low energy modes is linked to the presence of large displacements of the light atoms, i.e., B and C, which is unusual in view of the rather low phonon energies. Specific modes exhibiting a strong coupling to the electronic quasiparticles were investigated as a function of temperature. Their energies and line widths showed marked changes on cooling from room temperature to just above the superconducting transition at T-c = 15.2 K. Calculations simulating the effects of temperature allow us to model the observed temperature dependence qualitatively.

The solvent exposure of protein surface residues changes when glycerol is introduced. The dynamic behavior of the protein, as quantified by the incoherent intermediate scattering function, shows a nonmonotonic dependence on glycerol content. The fluctuations of the protein residues with respect to each other were found to be similar in all water-containing solvents, but different from the pure glycerol case. The increase in the number of protein-glycerol hydrogen bonds in glycerol-water binary mixtures explains the slowing down of protein dynamics as the glycerol content increases. We also explored the dynamic behavior of the hydration layer. We show that the short length scale dynamics of this layer are insensitive to glycerol concentration. However, the long length scale behavior shows a significant dependence on glycerol content. We also provide insights into the behavior of bound and mobile water molecules.

Radiance, a lighting simulation program, has been used to conduct daylighting simulations for CFS. Depending on the configurations, the simulation can take hours or even days using a personal computer. This paper describes how to accelerate the matrix multiplication portion of a Radiance three-phase daylight simulation by conducting parallel computing on heterogeneous hardware of a personal computer. The algorithm was optimized and the computational part was implemented in parallel using OpenCL. The speed of the new approach was evaluated using various daylighting simulation cases on a multi-core central processing unit (CPU) and a graphics processing unit (GPU). Based on the measurements and analysis of the time usage for the Radiance daylighting simulation, further speedups can be achieved using fast input/output devices and storing the data in a binary format.

TI Measurement of charged jet suppression in Pb-Pb collisions at root s(NN)=2.76 TeV SO JOURNAL OF HIGH ENERGY PHYSICS LA English DT Article DE Jets; Heavy Ions ID LARGE TRANSVERSE-MOMENTUM; INDUCED GLUON RADIATION; PARTICLE PRODUCTION; DEPENDENCE; DETECTOR; PP AB A measurement of the transverse momentum spectra of jets in Pb-Pb collisions at root s(NN) = 2.76 TeV is reported. Jets are reconstructed from charged particles using the anti-k(T) jet algorithm with jet resolution parameters R of 0.2 and 0.3 in pseudorapidity vertical bar eta vertical bar < 0.5. The transverse momentum p(T) of charged particles is measured down to 0.15 GeV/c which gives access to the low p(T) fragments of the jet. Jets found in heavy-ion collisions are corrected event-by-event for average background density and on an inclusive basis (via unfolding) for residual background fluctuations and detector effects. A strong suppression of jet production in central events with respect to peripheral events is observed. The suppression is found to be similar to the suppression of charged hadrons, which suggests that substantial energy is radiated at angles larger than the jet resolution parameter R = 0.3 considered in the analysis. The fragmentation bias introduced by selecting jets with a high p(T) leading particle, which rejects jets with a soft fragmentation pattern, has a similar effect on the jet yield for central and peripheral events. The ratio of jet spectra with R = 0.2 and R = 0.3 is found to be similar in Pb-Pb and simulated PYTHIA pp events, indicating no strong broadening of the radial jet structure in the reconstructed jets with R < 0.3.

TI Topological Kondo effect in star junctions of Ising magnetic chains: exact solution SO NEW JOURNAL OF PHYSICS LA English DT Article DE Majorana fermions; Kondo effect; exact solution ID FIELD-THEORY; MODEL; INTEGRABILITY AB In this paper, I present a conjecture for the Bethe ansatz equations for the model describing a star junction of M quantum critical Ising chains. For M > 3 such a model exhibits the so-called topological Kondo effect (Beri and Cooper 2012 Phys. Rev. Lett. 109 156803) related to the existence of Majorana zero energy modes at the junction. These modes are of a topological nature; they non-locally encode an SO(M) 'spin' which is screened by the collective excitations of the chains. For certain values of M, the model is equivalent to the Kondo models with a known exact solution. These cases are used to check the validity of the conjecture. It is demonstrated that the model behaves differently for M even and odd; in the former case the model has a Fermi liquid and the latter case corresponds to a non-Fermi liquid infrared fixed point.

TI ATP-driven Rad50 conformations regulate DNA tethering, end resection, and ATM checkpoint signaling SO EMBO JOURNAL LA English DT Article DE DNA damage signaling; DNA repair; double-strand breaks; protein-DNA interactions ID DOUBLE-STRAND-BREAK; KINASE-ACTIVITY; MRE11/RAD50 COMPLEX; CRYSTAL-STRUCTURE; FISSION YEAST; MRN COMPLEX; REPAIR; MRE11; BINDING; RECOMBINATION AB The Mre11-Rad50 complex is highly conserved, yet the mechanisms by which Rad50 ATP-driven states regulate the sensing, processing and signaling of DNA double-strand breaks are largely unknown. Here we design structure-based mutations in Pyrococcus furiosus Rad50 to alter protein core plasticity and residues undergoing ATP-driven movements within the catalytic domains. With this strategy we identify Rad50 separation-of-function mutants that either promote or destabilize the ATP-bound state. Crystal structures, X-ray scattering, biochemical assays, and functional analyses of mutant PfRad50 complexes show that the ATP-induced closed conformation promotes DNA end binding and end tethering, while hydrolysis-induced opening is essential for DNA resection. Reducing the stability of the ATP-bound state impairs DNA repair and Tel1 (ATM) checkpoint signaling in Schizosaccharomyces pombe, double-strand break resection in Saccharomyces cerevisiae, and ATM activation by human Mre11-Rad50-Nbs1 in vitro, supporting the generality of the P.furiosus Rad50 structure-based mutational analyses. These collective results suggest that ATP-dependent Rad50 conformations switch the Mre11-Rad50 complex between DNA tethering, ATM signaling, and 5 strand resection, revealing molecular mechanisms regulating responses to DNA double-strand breaks.

TI Toward Equatorial Planarity about Uranyl: Synthesis and Structure of Tridentate Nitrogen-Donor {UO2}(2+) Complexes SO INORGANIC CHEMISTRY LA English DT Article ID TRIPLE-HELICAL COMPLEXES; X-RAY MICROSCOPY; TOTAL-ENERGY CALCULATIONS; AUGMENTED-WAVE METHOD; CRYSTAL-STRUCTURES; OF-PLANE; AROMATIC LIGANDS; ELECTRON-GAS; BASIS-SET; COORDINATION AB The reaction of UO2Cl2 center dot 3THF with the tridentate nitrogen donor ligand 2,6-bis(2-benzimidazolyl)pyridine (H2BBP) in pyridine leads to the formation of three different complexes: [(UO2)(H2BBP)Cl-2] (1), [(UO)(2)(HBBP)(Py)Cl] (2), and [(UO2)-(BBP)(Py)(2)] (3) after successive deprotonation of H2BBP with a strong base. Crystallographic determination of 1-3 reveals that increased charge through ligand deprotonation and displacement of chloride leads to equatorial planarity about uranyl as well as a more compact overall coordination geometry. Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectra of 1-3 at the U-4d edges have been recorded using a soft X-ray Scanning Transmission X-ray Microscope (STXM) and reveal the uranium 4d(5/2) and 4d(3/2) transitions at energies associated with uranium in the hexavalent oxidation state. First-principles Density Functional Theory (DFT) electronic structure calculations for the complexes have been performed to determine and validate the coordination characteristics, which correspond well to the experimental results.

Single crystals (both are in the triclinic crystal system) were oriented to give vibrational spectra perpendicular to the porphyrin plane. Additionally, two orthogonal in-plane measurements that were also either perpendicular or parallel to the projection of the FeNO plane onto the porphyrin plane yield the complete set of vibrations with iron motion. In addition to cleanly enabling the assignment of the FeNO bending and stretching modes, the measurements reveal that the two in-plane spectra from the parallel and perpendicular in-plane directions for both compounds have substantial differences. The assignment of these in-plane vibrations were aided by density functional theory predictions. The differences in the two in-plane directions result from the strongly bonded axial NO ligand. The direction of the in-plane iron motion is thus found to be largely parallel and perpendicular to the projection of the FeNO plane on the porphyrin plane. These axial ligand effects on the in-plane iron motion are related to the strength of the axial ligand-to-iron bond. C1 [Paylik, Jeffrey W.; Peng, Qian; Silvernail, Nathan J.; Scheidt, W.

The ability to monitor stoichiometry is important, since it has been shown to impact carrier recombination. Te-rich samples show transitions corresponding to acceptor-bound excitons (similar to 1.58 eV) and free-electron to acceptor transitions (similar to 1.547 eV). In addition to acceptor-bound excitons, Cd-rich samples show transitions assigned to donor-bound excitons (1.591 eV) and Te vacancies at 1.552 eV. Photoluminescence is a noninvasive way to monitor stoichiometric shifts induced by post-deposition anneals in polycrystalline CdTe thin films deposited by close-spaced sublimation.

TI Decrease of the surface resistance in superconducting niobium resonator cavities by the microwave field SO APPLIED PHYSICS LETTERS LA English DT Article ID KAPITZA RESISTANCE; SUPERFLUID AB Measurements of the quality factor, Q, of Nb superconducting microwave resonators often show that Q increases by similar or equal to 10%-30% with increasing radio-frequency (rf) field, H, up to similar to 15-20mT. Recent high temperature heat treatments can amplify this rf field-induced increase of Q up to similar or equal to 50%-100% and extend it to much higher fields similar or equal to 100mT, but the mechanisms of the enhancement of Q(H) remain unclear. Here, we suggest a method to reveal these mechanisms by measuring temperature dependencies of Q at different rf field amplitudes. We show that the increase of Q(H) does not come from a field dependent quasi-particles activation energy or residual resistance, but rather results from the smearing of the density of state by the rf field.

The films exhibited a superconducting gap of 2meV and 2.4meV, respectively, with a corresponding critical temperature of 11.5K and 13.4K, among the highest reported T-c values achieved by the ALD technique. Tunnel junctions were obtained using a mechanical contact method with a Au tip. While the native oxides of these films provided poor tunnel barriers, high quality tunnel junctions with low zero bias conductance (below similar to 10%) were obtained using an artificial tunnel barrier of Al2O3 on the film's surface grown ex situ by ALD. We find a large critical current density on the order of 4 x 10(6) A/cm(2) at T = 0.8T(c) for a 60 nm MoN film and demonstrate conformal coating capabilities of ALD onto high aspect ratio geometries. These results suggest that the ALD technique offers significant promise for thin film superconducting device applications. (C) 2014 AIP Publishing LLC.

Scanning probe microscopy (SPM) has emerged as a powerful tool both for studies of domain structures with nanoscale spatial resolution and for writing the isolated nanodomains by local application of the electric field. Quantitative analysis of the observed behavior requires understanding the role of environmental factors on imaging and switching process. Here, we study the influence of the relative humidity in the SPM chamber on tip-induced polarization switching. The observed effects are attributed to existence of a water meniscus between the tip and the sample surface in humid atmosphere. These results are important for a deeper understanding of complex investigations of ferroelectric materials and their applications and suggest the necessity for fundamental studies of electrocapillary phenomena at the tip-surface junction and their interplay with bias-induced materials responses.

TI Coherent acoustic phonon generation in GaAs1-xBix SO APPLIED PHYSICS LETTERS LA English DT Article ID GAAS; SUPERLATTICES; OSCILLATIONS; EXCITATION; BI AB We have used femtosecond laser pulses to generate coherent acoustic phonons in the dilute Bismide alloy, GaAs1-xBix. The observed oscillation periods match well with the oscillation periods calculated using the propagating strain pulse model. We attribute the generation process predominantly to electronic stress due to the absorption of the laser pulse at the surface of the GaAs1-xBix layer. Our initial estimates suggest that the incorporation of Bi in GaAs causes an enhancement of the hydrostatic deformation potential because of the resonant state in the valence band due to isolated Bi impurities.

We present a detailed study of the bias dependence of the diamond responsivity across the carbon k-edge. The carrier loss is modelled by incorporating a characteristic recombination length into the absorption model and is shown to agree well with Monte Carlo simulated carrier losses. Using the high sensitivity to the x-ray absorption depth, the responsivity is converted to a near edge x-ray absorption fine structure pattern allowing easy identification of absorption mechanisms.

It serves as a building block for a wide variety of plastics, textiles, and chemicals, and a process has been developed for its conversion into liquid transportation fuels. Currently, commercial ethylene production involves steam cracking of fossil fuels, and is the highest CO2-emitting process in the chemical industry. Therefore, there is great interest in developing technology for ethylene production from renewable resources including CO2 and biomass. Ethylene is produced naturally by plants and some microbes that live with plants. One of the metabolic pathways used by microbes is via an ethylene-forming enzyme (EFE), which uses a-ketoglutarate and arginine as substrates. EFE is a promising biotechnology target because the expression of a single gene is sufficient for ethylene production in the absence of toxic intermediates. Here we present the first comprehensive review and analysis of EFE, including its discovery, sequence diversity, reaction mechanism, predicted involvement in diverse metabolic modes, heterologous expression, and requirements for harvesting of bioethylene. A number of knowledge gaps and factors that limit ethylene productivity are identified, as well as strategies that could guide future research directions.

TI Twistl-induced dissemination preserves epithelial identity and requires E-cadherin SO JOURNAL OF CELL BIOLOGY LA English DT Article ID BREAST-CANCER; BRANCHING MORPHOGENESIS; MESENCHYMAL TRANSITION; TUMOR PROGRESSION; MAMMARY-GLAND; BHLH FACTORS; EXPRESSION; METASTASIS; CARCINOMA; CELLS AB Dissemination of epithelial cells is a critical step in metastatic spread. Molecular models of dissemination focus on loss of E-cadherin or repression of cell adhesion through an epithelial to mesenchymal transition (EMT). We sought to define the minimum molecular events necessary to induce dissemination of cells out of primary murine mammary epithelium. Deletion of E-cadherin disrupted epithelial architecture and morphogenesis but only rarely resulted in dissemination. In contrast, expression of the EMT transcription factor Twistl induced rapid dissemination of cytokeratin-positive epithelial cells. Twist) induced dramatic transcriptional changes in extracellular compartment and cell matrix adhesion genes but not in cell cell adhesion genes. Surprisingly, we observed disseminating cells with membrane-localized E-cadherin and p-catenin, and E-cadherin knockdown strongly inhibited Twist) -induced single cell dissemination. Dissemination can therefore occur with retention of epithelial cell identity. The spread of cancer cells during metastasis could similarly involve activation of an epithelial motility program without requiring a transition from epithelial to mesenchymal character.

However, the molecular mechanisms underlying these changes remain poorly understood. Here, we characterize the phenotypes induced by maternal obesity in a mouse model and examine gene expression and epigenetic changes induced by maternal diet in adult offspring. Methods: We analyzed genetically identical male mice born from dams fed a high-or low-fat diet throughout pregnancy and until day 21 postpartum. After weaning, half of the males of each group were fed a high-fat diet, the other half a low-fat diet. We first characterized the genome-wide gene expression patterns of six tissues of adult offspring - liver, pancreas, white adipose, brain, muscle and heart. We then measured DNA methylation patterns in liver at selected loci and throughout the genome. Results: Maternal diet had a significant effect on the body weight of the offspring when they were fed an obesogenic diet after weaning. Our analyses showed that maternal diet had a pervasive effect on gene expression, with a pronounced effect in liver where it affected many genes involved in inflammation, cholesterol synthesis and RXR activation. We did not detect any effect of the maternal diet on DNA methylation in the liver. Conclusions: Overall, our findings highlighted the persistent influence of maternal diet on adult tissue regulation and suggested that the transcriptional changes were unlikely to be caused by DNA methylation differences in adult liver.

SHS contains chemicals that have been implicated in causing oxidative DNA damage in the airway epithelium. Although DNA repair is considered a key defensive mechanism against various environmental attacks, such as cigarette smoking, the associations of individual repair enzymes with susceptibility to lung cancer are largely unknown. This study investigated the role of NEIL2, a DNA glycosylase excising oxidative base lesions, in human lung cells treated with sidestream smoke (SSS), the main component of SHS. To do so, we generated NEIL2 knockdown cells using siRNA-technology and exposed them to SSS-laden medium. Representative SSS chemical compounds in the medium were analyzed by mass spectrometry. An increased production of reactive oxygen species (ROS) in SSS-exposed cells was detected through the fluorescent detection and the induction of HIF-1 alpha. The long amplicon-quantitative PCR (LA-QPCR) assay detected significant dose-dependent increases of oxidative DNA damage in the HPRT gene of cultured human pulmonary fibroblasts (hPF) and BEAS-2B epithelial cells exposed to SSS for 24 h. These data suggest that SSS exposure increased oxidative stress, which could contribute to SSS-mediated toxicity. siRNA knockdown of NEIL2 in hPF and HEK 293 cells exposed to SSS for 24 h resulted in significantly more oxidative DNA damage in HPRT and POLB than in cells with control siRNA. Taken together, our data strongly suggest that decreased repair of oxidative DNA base lesions due to an impaired NEIL2 expression in non-smokers exposed to SSS would lead to accumulation of mutations in genomic DNA of lung cells over time, thus contributing to the onset of SSS-induced lung cancer.

TI Evoked and Spontaneous Transmission Favored by Distinct Sets of Synapses SO CURRENT BIOLOGY LA English DT Article ID NEUROTRANSMITTER RELEASE; ACTIVE ZONE; SYNAPTIC-TRANSMISSION; DROSOPHILA; BRUCHPILOT; PROTEIN; PHILANTHOTOXINS; MATURATION; DEPRESSION; FUSION AB Background: Spontaneous "miniature" transmitter release takes place at low rates at all synapses. Long thought of as an unavoidable leak, spontaneous release has recently been suggested to be mediated by distinct pre- and postsynaptic molecular machineries and to have a specialized role in setting up and adjusting neuronal circuits. It remains unclear how spontaneous and evoked transmission are related at individual synapses, how they are distributed spatially when an axon makes multiple contacts with a target, and whether they are commonly regulated. Results: Electrophysiological recordings in the Drosophila larval neuromuscular junction, in the presence of the use-dependent glutamate receptor (GluR) blocker philanthotoxin, indicated that spontaneous and evoked transmission employ distinct sets of GluRs. In vivo imaging of transmission using synaptically targeted GCaMP3 to detect Ca2+ influx through the GluRs revealed little spatial overlap between synapses participating in spontaneous and evoked transmission. Spontaneous and evoked transmission were oppositely correlated with presynaptic levels of the protein Brp: synapses with high Brp favored evoked transmission, whereas synapses with low Brp were more active spontaneously. High-frequency stimulation did not increase the overlap between evoked and spontaneous transmission, and instead decreased the rate of spontaneous release from synapses that were highly active in evoked transmission. Conclusions: Although individual synapses can participate in both evoked and spontaneous transmission, highly active synapses show a preference for one mode of transmission. The presynaptic protein Brp promotes evoked transmission and suppresses spontaneous release. These findings suggest the existence of presynaptic mechanisms that promote synaptic specialization to either evoked or spontaneous transmission.

The sound-velocity limited evolution of the observed lattice strains indicates a quasi-instantaneous photoinduced stress which decays on a nanosecond time scale. This stress exhibits an inhomogeneous spatial profile evidenced by the broadening of the Bragg peak. These new data require substantial modification of existing models of photogenerated stresses in BiFeO3: the relevant excited charge carriers must remain localized to be consistent with the data.

TI Solidification of GTA Aluminum Weld Metal: Part 2-Thermal Conditions and Model for Columnar-to-Equiaxed Transition SO WELDING JOURNAL LA English DT Article ID GRAIN-REFINEMENT; HOT CRACKING; PARAMETERS; MECHANISM; ALLOYS; GROWTH AB In this study, the influence of solute content and heat input on microstructure was investigated for gas tungsten arc (GTA) bead-on-plate welding of the aluminum alloys 1050A (Al 99.5) and 6082 (Al Si1MgMn). Temperature measurements in the solidifying weld pool showed that parameters such as solidification growth rate, cooling rate, local thermal gradient, and solidification time vary significantly along the solidification front (between weld centerline and weld interface). As a result, the obtained thermal data were used to explain the corresponding grain morphology from the first part of this study. On the basis of this comparison, an analytical approach was used to model the transition from columnar-to-equiaxed grain growth (CET). This model allows the prediction of critical values for both solidification growth rate and thermal gradient, at which the CET occurs.

TI Statistical Emulation of Climate Model Projections Based on Precomputed GCM Runs SO JOURNAL OF CLIMATE LA English DT Article DE Statistics; General circulation models; Model output statistics ID PERTURBED PHYSICS ENSEMBLES; COMPUTER-MODEL; SYSTEM PROPERTIES; CHANGE SCENARIOS; PREDICTABILITY; CALIBRATION; UNCERTAINTY; RESOLUTION; FRAMEWORK; OUTPUTS AB The authors describe a new approach for emulating the output of a fully coupled climate model under arbitrary forcing scenarios that is based on a small set of precomputed runs from the model. Temperature and precipitation are expressed as simple functions of the past trajectory of atmospheric CO2 concentrations, and a statistical model is fit using a limited set of training runs. The approach is demonstrated to be a useful and computationally efficient alternative to pattern scaling and captures the nonlinear evolution of spatial patterns of climate anomalies inherent in transient climates. The approach does as well as pattern scaling in all circumstances and substantially better in many; it is not computationally demanding; and, once the statistical model is fit, it produces emulated climate output effectively instantaneously. It may therefore find wide application in climate impacts assessments and other policy analyses requiring rapid climate projections.

TI Solid oxide fuel cells for power generation SO WILEY INTERDISCIPLINARY REVIEWS-ENERGY AND ENVIRONMENT LA English DT Review ID TECHNOLOGY AB Solid oxide fuel cells (SOFCs), based on an oxide ion conducting electrolyte, offer a clean, low-pollution technology to electrochemically generate electricity at high efficiencies. These fuel cells provide many advantages over traditional energy conversion systems including high efficiency, reliability, modularity, fuel adaptability, and very low levels of SOx and NOx emissions. Quiet, vibration-free operation of SOFCs also eliminates noise usually associated with conventional power generation systems. Furthermore, because of their high operation temperature (600-1000 degrees C), some hydrocarbon fuels such as natural gas can be reformed within the cell stack eliminating the need for an expensive, external reformer. In spite of these advantages, the degree and extent of their market penetration really depends on the ability to reduce the cost of SOFC-based power systems while ensuring their long-term durability. This article reviews the cell and stack materials, cell designs, and present commercial status of power systems built using SOFCs. (C) 2013 John Wiley & Sons, Ltd.

The reduction of U(VI) to U(IV) by Shewanella oneidensis strain MR-1 leads to the precipitation of the mineral uraninite, as well as a non-crystalline U(IV) product. The wild-type (WT) strain can produce extracellular polymeric substances (EPS), prompting precipitation of U some distance from the cells and precluding encrustation. Using cryo-transmission electron microscopy and scanning transmission X-ray microscopy we show that, in the biofilm-deficient mutant Delta mxdA, as well as in the WT strain to a lesser extent, we observe the formation of membrane vesicles (MVs) as an additional means to lessen encrustation. Additionally, under conditions in which the WT does not produce EPS, formation of MVs was the only observed mechanism to mitigate cell encrustation. Viability studies comparing U-free controls to cells exposed to U showed a decrease in the number of viable cells in conditions where MVs alone are detected, yet no loss of viability when cells produce both EPS and MVs. We conclude that MV formation is a microbial strategy to shed encrusted cell surfaces but is less effective at maintaining cell viability than the precipitation of U on EPS.

TI Estimates of Uncertainty in Multi-Zone Air Leakage Measurements SO INTERNATIONAL JOURNAL OF VENTILATION LA English DT Article DE air tightness; multi-zone; uncertainty; air leakage measurements AB Although standards for single-zone air leakage tests are widely used, there are no existing standards for several multi-zone cases including: 1) testing air leakage between adjacent zones or 2) testing leakage to the outside from a single unit in a multi-zone building. While a range of test procedures have been used to determine inter-zone leakage using fan-pressurization, the accuracy of the methods can vary significantly. Using field measurements and simulations, we compared the uncertainty in the leakage between two adjacent zones for different measurement and calculation methods. The most accurate method for determining leakage between two adjacent zones using a single blower door has 25% uncertainty and the most accurate two-door test has 16%. In multi-family housing buildings, air leakage from a single zone to the outside is often measured by pressurizing adjacent units to the same test pressure, i.e., a guarded test approach. We investigated how two common sources of uncertainty affect zone-to-outside leakage test results using the guarded zone test method: 1) pressure fluctuations in the different units, and 2) interconnected zones that are not pressurized during the test. While the uncertainty in leakage to outside due to pressure fluctuations and calibration error in guarded test results is relatively small (4-14%), leakage to interstitial zones may have a much more substantial impact (on the order of 30-100% of the leakage directly to the outdoors).

The method has been implemented online in a sandbox environment (i.e., a security mechanism for separating running programs) at Los Alamos National Laboratory, and is intended for eventual host-based use, provided the issue of sampling the instructions executed by a given process without disruption to the user can be satisfactorily addressed. The procedure represents an instruction trace with a Markov chain structure in which the transition matrix, P, has rows modeled as Dirichlet vectors. The malware class (malicious or benign) is modeled using a flexible spline logistic regression model with variable selection on the elements of P, which are observed with error. The utility of the method is illustrated on a sample of traces from malware and nonmalware programs, and the results are compared to other leading detection schemes (both signature and classification based).

TI Experimental determination of the speciation, partitioning, and release of perrhenate as a chemical surrogate for pertechnetate from a sodalite-bearing multiphase ceramic waste form SO APPLIED GEOCHEMISTRY LA English DT Article ID INTERFACIAL DISSOLUTION-REPRECIPITATION; HANFORD TANK WASTE; CRYSTAL-STRUCTURE; HYPERALKALINE CONDITIONS; PHASE TRANSFORMATIONS; HIGH-LEVEL; GLASS; CESIUM; NMR; CANCRINITE AB A key component to closing the nuclear fuel cycle is the storage and disposition of nuclear waste in geologic systems. Multiphase ceramic waste forms have been studied extensively as a potential host matrix for nuclear waste. Understanding the speciation, partitioning, and release behavior of radionuclides immobilized in multiphase ceramic waste forms is a critical aspect of developing the scientific and technical basis for nuclear waste management. In this study, we evaluated a sodalite-bearing multiphase ceramic waste form (i.e., fluidized-bed steam reform sodium aluminosilicate [FBSR NAS] product) as a potential host matrix for long-lived radionuclides, such as technetium (Tc-99). The FBSR NAS material consists primarily of nepheline (ideally NaAlSiO4), anion-bearing sodalites (ideally M-8[Al6Si6O24]X-2, where M refers to alkali and alkaline earth cations and X refers to monovalent anions), and nosean (ideally Na-8[AlSiO4](6)SO4). Bulk X-ray absorption fine structure analysis of the multiphase ceramic waste form, suggest rhenium (Re) is in the Re(VII) oxidation state and has partitioned to a Re-bearing sodalite phase (most likely a perrhenate sodalite Na-8[Al6Si6O24](ReO4)(2)). Rhenium was added as a chemical surrogate for 99Tc during the FBSR NAS synthesis process. The weathering behavior of the FBSR NAS material was evaluated under hydraulically unsaturated conditions with deionized water at 90 degrees C. The steady-state Al, Na, and Si concentrations suggests the weathering mechanisms are consistent with what has been observed for other aluminosilicate minerals and include a combination of ion exchange, network hydrolysis, and the formation of an enriched-silica surface layer or phase. The steady-state S and Re concentrations are within an order of magnitude of the nosean and perrhenate sodalite solubility, respectively. The order of magnitude difference between the observed and predicted concentration for Re and S may be associated with the fact that the anion-bearing sodalites contained in the multiphase ceramic matrix are present as mixed-anion sodalite phases. These results suggest the multiphase FBSR NAS material may be a viable host matrix for long-lived, highly mobilie radionuclides which is a critical aspect in the management of nuclear waste.

TI Geochemical and mineralogical investigation of uranium in multi-element contaminated, organic-rich subsurface sediment SO APPLIED GEOCHEMISTRY LA English DT Article ID RAY-ABSORPTION SPECTROSCOPY; ADSORPTION; COMPLEXATION; U(VI); GOETHITE; HEMATITE; SORPTION; SURFACE; URANYL; REDUCTION AB Subsurface regions of alluvial sediments characterized by an abundance of refractory or lignitic organic carbon compounds and reduced Fe and S bearing minerals, which are referred to as naturally reduced zones (NRZ), are present at the Integrated Field Research Challenge site in Rifle, CO (a former U mill site), and other contaminated subsurface sites. A study was conducted to demonstrate that the NRZ contains a variety of contaminants and unique minerals and potential contaminant hosts, investigate micron-scale spatial association of U with other co-contaminants, and determine solid phase-bounded U valence state and phase identity. The NRZ sediment had significant solid phase concentrations of U and other co-contaminants suggesting competing sorption reactions and complex temporal variations in dissolved contaminant concentrations in response to transient redox conditions, compared to single contaminant systems. The NRZ sediment had a remarkable assortment of potential contaminant hosts, such as Fe oxides, siderite, Fe(II) bearing clays, rare solids such as ZnS framboids and CuSe, and, potentially, chemically complex sulfides. Micron-scale inspections of the solid phase showed that U was spatially associated with other co-contaminants. High concentration, multi-contaminant, micron size (ca. 5-30 mu m) areas of mainly U(IV) (53-100%) which occurred as biogenic UO2 (82%), or biomass - bound monomeric U(IV) (18%), were discovered within the sediment matrix confirming that biotically induced reduction and subsequent sequestration of contaminant U(VI) via natural attenuation occurred in this NRZ. A combination of assorted solid phase species and an abundance of redox-sensitive constituents may slow U(IV) oxidation rates, effectively enhancing the stability of U(IV) sequestered via natural attenuation, impeding rapid U flushing, and turning NRZs into sinks and long-term, slow-release sources of U contamination to groundwater.

This 41 013-bp plasmid showed no homology to any of the previously sequenced Francisella plasmids and was 8-10 times larger in size than them. A total of 57 ORFs were identified within pFNPA10 and at least 9 of them encoded putative proteins with homology to different conjugal transfer proteins. The presence of iteron-like direct repeats and an ORF encoding a putative replication protein within pFNPA10 suggested that it replicated by the theta mode. Phylogenetic analyses indicated that pFNPA10 had no near neighbors in the databases and that it may have originated within an environmental Francisella lineage. Based on its features, pFNPA10 appears to be a novel extra-chromosomal genetic element within the genus Francisella. The suitability of pFNPA10 as a vector for transformation of species of Francisella by conjugation remains to be explored.

TI Physical constraints on geologic CO2 sequestration in low-volume basalt formations SO GEOLOGICAL SOCIETY OF AMERICA BULLETIN LA English DT Article ID SNAKE RIVER PLAIN; CARBON-DIOXIDE; MINERAL CARBONATION; LAVA FLOWS; IDAHO; FRACTURE; STORAGE; RESERVOIRS AB Deep basalt formations within large igneous provinces have been proposed as target reservoirs for carbon capture and sequestration on the basis of favorable CO2 -water-rock reaction kinetics that suggest carbonate mineralization rates on the order of 10(2)-10(3) d. Although these results are encouraging, there exists much uncertainty surrounding the influence of fracture-controlled reservoir heterogeneity on commercial-scale CO2 injections in basalt formations. This work investigates the physical response of a low-volume basalt reservoir to commercial-scale CO2 injections using a Monte Carlo numerical modeling experiment such that model variability is solely a function of spatially distributed reservoir heterogeneity. Fifty equally probable reservoirs are simulated using properties inferred from the deep eastern Snake River Plain aquifer in southeast Idaho, and CO2 injections are modeled within each reservoir for 20 yr at a constant mass rate of 21.6 kg s(-1). Results from this work suggest that (1) formation injectivity is generally favorable, although injection pressures in excess of the fracture gradient were observed in 4% of the simulations; (2) for an extensional stress regime (as exists within the eastern Snake River Plain), shear failure is theoretically possible for optimally oriented fractures if S-h <= 0.70S(v); and (3) low-volume basalt reservoirs exhibit sufficient CO2 confinement potential over a 20 yr injection program to accommodate mineral trapping rates suggested in the literature.

This significantly impacts the quality of global, low-dimensional space embedding procedures such as the popular multidimensional scaling (MDS) where one can often observe nonintuitive layouts. We were inspired by the perceptual processes evoked in the method of parallel coordinates which enables users to visually aggregate the data by the patterns the polylines exhibit across the dimension axes. We call the path of such a polyline its structure and suggest a metric that captures this structure directly in high-dimensional space. This allows us to better gauge the distances of spatially distant data constellations and so achieve data aggregations in MDS plots that are more cognizant of existing high-dimensional structure similarities. Our biscale framework distinguishes far-distances from near-distances. The coarser scale uses the structural similarity metric to separate data aggregates obtained by prior classification or clustering, while the finer scale employs the appropriate euclidean distance.

Consequently, noninvasive methods of monitoring blood vessel size, density, and oxygenation would be valuable. Simple spectroscopy employing fiber optic probes to measure backscattering can potentially determine hemoglobin parameters. However, heterogeneity of blood distribution, the dependence of the tissue-volume-sampled on scattering and absorption, and the potential compression of tissue all hinder the accurate determination of hemoglobin parameters. We address each of these issues. A simple derivation of a correction factor for the absorption coefficient, mu(a), is presented. This correction factor depends not only on the vessel size, as others have shown, but also on the density of blood vessels. Monte Carlo simulations were used to determine the dependence of an effective pathlength of light through tissue which is parameterized as a ninth-order polynomial function of mu(a). The hemoglobin bands of backscattering spectra of cervical tissue are fit using these expressions to obtain effective blood vessel size and density, tissue hemoglobin concentration, and oxygenation. Hemoglobin concentration and vessel density were found to depend on the pressure applied during in vivo acquisition of the spectra. It is also shown that determined vessel size depends on the blood hemoglobin concentration used. (C) The Authors.

By analysis of the microscale deformation of a two-component layered medium, it is shown that nonlocal interactions necessarily appear in a homogenized model of the system. Explicit expressions for the nonlocal forces are determined. The way these nonlocal forces appear in various nonlocal elasticity theories is derived. The length scales that emerge involve the constituent material properties as well as their geometrical dimensions. A peridynamic material model for the smoothed displacement field is derived. It is demonstrated by comparison with experimental data that the incorporation of nonlocality in modeling improves the prediction of the stress concentration in an open-hole tension test on a composite plate.

TI Dimerization of VirD2 Binding Protein Is Essential for Agrobacterium Induced Tumor Formation in Plants SO PLOS PATHOGENS LA English DT Article ID IV SECRETION SYSTEMS; DNA TRANSFER; TUMEFACIENS; BACTERIAL; TRANSFORMATION; SUBSTRATE; DIVERSITY; INFECTION; APPARATUS; DOMAIN AB The Type IV Secretion System (T4SS) is the only bacterial secretion system known to translocate both DNA and protein substrates. The VirB/D4 system from Agrobacterium tumefaciens is a typical T4SS. It facilitates the bacteria to translocate the VirD2-T-DNA complex to the host cell cytoplasm. In addition to protein-DNA complexes, the VirB/D4 system is also involved in the translocation of several effector proteins, including VirE2, VirE3 and VirF into the host cell cytoplasm. These effector proteins aid in the proper integration of the translocated DNA into the host genome. The VirD2-binding protein (VBP) is a key cytoplasmic protein that recruits the VirD2-T-DNA complex to the VirD4-coupling protein (VirD4 CP) of the VirB/D4 T4SS apparatus. Here, we report the crystal structure and associated functional studies of the C-terminal domain of VBP. This domain mainly consists of a-helices, and the two monomers of the asymmetric unit form a tight dimer. The structural analysis of this domain confirms the presence of a HEPN (higher eukaryotes and prokaryotes nucleotide-binding) fold. Biophysical studies show that VBP is a dimer in solution and that the HEPN domain is the dimerization domain. Based on structural and mutagenesis analyses, we show that substitution of key residues at the interface disrupts the dimerization of both the HEPN domain and full-length VBP. In addition, pull-down analyses show that only dimeric VBP can interact with VirD2 and VirD4 CP. Finally, we show that only Agrobacterium harboring dimeric full-length VBP can induce tumors in plants. This study sheds light on the structural basis of the substrate recruiting function of VBP in the T4SS pathway of A. tumefaciens and in other pathogenic bacteria employing similar systems.

A paradigm of topology/geometry -> property -> functionality is emerging that goes beyond the traditional microscopic structure -> property -> functionality relationship. The new approach delineates the active roles of topology and geometry in design, fabrication, characterization, and predictive modeling of novel materials properties and multifunctionalities. After introducing the essentials of topology and geometry, we elucidate these concepts through a gamut of nanocarbon allotropes of de novo carbons, hierarchical self-assembled soft- and biomaterials, supramolecular assemblies, and nanoporous materials. Applications of these topological materials range from sensing, energy storage/conversion, and catalysis to nanomedicine. C1 [Gupta, Sanju] Western Kentucky Univ, Bowling Green, KY 42101 USA.

Experiments were performed at Reynolds numbers of the order of Re similar to 10(4) as the interaction parameter N, representing the ratio of electromagnetic forces to inertial forces, was increased through unity. The von KarmAn vortex street in the wake of the cylinder was observed by simultaneously sampling the gradient of the induced electric potential, del phi, at 16 cross-stream locations as a proxy for the streamwise fluid velocity. An ensemble of vortex velocity profiles was measured as a function of the applied magnetic field strength. Results indicate a significant change in the circulation of vortices and the deviations from the average profile as N was increased. By sampling the fluctuations in del phi at three locations in the wake, the decay of the vortices was examined and the effective viscosity was found to decrease as N-49 +/- 0 04. Using temperature as a passive tracer, qualitative observations were made with an infrared (IR) camera that showed significant changes in the wake, including the absence of small-scale structures at high magnetic field strengths. Collectively, the results suggest that the reduction in effective viscosity was due to the suppression of the small-scale eddies by the magnetic field. The slope of the power spectrum was observed to change from a k(-1.8) power law at low N to a k(-3.5) power law for N> 1. Together, these results suggest the flow smoothly transitioned from a hydrodynamic state to a magnetohydrodynamic regime over the range of 0p, Vs, density, etc.) at arbitrary latitude/longitude/depth points.

A wide range of reported values resulted from differences in the vintage of the data used to evaluate the ethanol conversion technology and the agricultural practices of corn production, which evolved substantially during the rapid growth phase of the industry. Methodological differences in life cycle assessments also caused the reported values to vary widely. With corn dry mills growing from 30% of total installed ethanol production capacity in 1990 to 80-90% from 2006 to 2011, we document the evolution of this industry using vintage-specific data to analyze selected energy and environmental metrics, including GHG emissions, fossil energy use, direct land use, and GHG emissions reduction per hectare of land harvested for ethanol production. Our estimates indicate that production and use of corn ethanol emitted 44% fewer GHG emissions, consumed 54% less fossil energy and required 44% less land in 2010 compared to 1990 (on a life cycle basis). Our review and analysis point to strategies for reducing the carbon footprint of the corn dry mill industry by building on the progress already achieved. Using biomass (e.g. residues from corn production) for process heat or combined heat and power is one such strategy. Additional environmental benefits are projected from the adoption of integrated gasification combined cycle technology (using corn residues), which leads to energy-self-sufficient mills or net electricity producers depending on the power system configuration.

TI Profitability of Cellulosic Biomass Production in the Northern Great Lakes Region SO AGRONOMY JOURNAL LA English DT Article ID LAND-USE CHANGE; BIOFUELS; CROPS; BIOENERGY; ETHANOL; ENERGY; EMISSIONS; WILLOW; COVER AB Producing bioenergy feedstocks on non-crop land can largely avoid the food price feedbacks of energy biomass production on cropland. The U.S. northern tier grassland-to-forest ecotone offers large areas of marginal land that is not currently cropped. In this ecological transition zone, the relative profitability of grassy vs. woody sources of energy biomass is little studied. This paper reports an exploratory investment analysis of cellulosic biomass production in the northern Great Lakes region. It compares two short-rotation tree crops, willow (Salix sachalinensis F. Schmidt) and hybrid poplar (Populus nigra L. X P. maximowiczii A. Henry), and switchgrass (Panicum virgatum L.) (a native prairie grass) to conventional mixed hay. Because biomass markets are not yet well developed, this study calculates threshold prices and yields at which biomass crops become at least as profitable as mixed grass hay. At 2010-2012 prices and available production technologies, none of the cellulosic crops is competitive with the hay baseline system. The breakeven price of energy biomass ranges from $90-100 per oven-dry Mg-1 for all three energy crops. Breakeven yields are much more variable, due to the high cost of harvesting woody biomass. At 2010-2012 prices, necessary biomass yield increases range from 3.5-fold for switchgrass and willow to over 25-fold for poplar. While the ratio of input costs to revenue remains relatively constant between the northern and southern Great Lakes regions, the opportunity cost of active cropland in the southern zone is much higher, implying an economic comparative advantage for marginal land of the northern tier of the Great Lakes region.

TI Productivity and Carbon Dioxide Exchange of Leguminous Crops: Estimates from Flux Tower Measurements SO AGRONOMY JOURNAL LA English DT Article ID NET ECOSYSTEM EXCHANGE; GROSS PRIMARY PRODUCTIVITY; LIGHT-RESPONSE PARAMETERS; WATER-USE EFFICIENCY; EDDY COVARIANCE; SOYBEAN CANOPY; ENERGY-BALANCE; UNITED-STATES; CO2 FLUX; RESPIRATION AB Net CO2 exchange data of legume crops at 17 flux tower sites in North America and three sites in Europe representing 29 site-years of measurements were partitioned into gross photosynthesis and ecosystem respiration by using the nonrectangular hyperbolic light-response function method. The analyses produced net CO2 exchange data and new ecosystem-scale ecophysiological parameter estimates for legume crops determined at diurnal and weekly time steps. Dynamics and annual totals of gross photosynthesis, ecosystem respiration, and net ecosystem production were calculated by gap filling with multivariate nonlinear regression. Comparison with the data from grain crops obtained with the same method demonstrated that CO2 exchange rates and ecophysiological parameters of legumes were lower than those of maize (Zea mays L.) but higher than for wheat (Triticum aestivum L.) crops. Year-round annual legume crops demonstrated a broad range of net ecosystem production, from sinks of 760 g CO2 m(-2) yr(-1) to sources of -2100 g CO2 m(-2) yr(-1), with an average of -330 g CO2 m(-2) yr(-1), indicating overall moderate CO2-source activity related to a shorter period of photosynthetic uptake and metabolic costs of N-2 fixation. Perennial legumes (alfalfa, Medicago sativa L.) were strong sinks for atmospheric CO2, with an average net ecosystem production of 980 (range 550-1200) g CO2 m(-2) yr(-1).

The purpose of this research is to quantify relative price relationships due to a wide range of measurable hay characteristics of a specific hay auction reflecting supply and demand preferences. A time series data set was developed based on USDA Agricultural Marketing Service (AMS) reporting of the Colorado Centennial Hay Auction 2006 to 2011. All bale characteristics were gleaned from the reports including the number of tonnes offered at auction, hay type, grade, size, year, month, and the number of tonnes offered of a specific hay type, grade, size, year, and month combination. The data set was used to create a hedonic statistical price model for three hay types: alfalfa (Medicago sativa L.), mixed alfalfa/grass, and grass hay. Time trend variables, grade, size, and the number of tonnes offered all proved to significantly impact price. Th largest price increases were associated with specific grade size combinations, such as supreme quality small square bales. Th biggest price reductions were associated with larger sized bales and lower quality grades. Alfalfa prices were the highest in this auction; the largest price variability was in grass hay. Results are largely applicable to a market area which includes buyers of hay for all types of livestock. Hay producers should carefully consider quality, type of hay (e.g., alfalfa), and bale characteristics in their production decisions.

TI Contribution of deep-level defects to decreasing radiative efficiency of InGaN/GaN quantum wells with increasing emission wavelength SO APPLIED PHYSICS EXPRESS LA English DT Article ID GAN; CARBON; DISTRIBUTIONS; DIODES AB Deep-level optical spectroscopy (DLOS) and photoluminescence (PL) were used to understand the role of defects in reducing the internal quantum efficiency (IQE) of InxGa1-xN/GaN multiple quantum wells (MQWs) as the emission wavelength increased from approximately 450 to 530 nm, i.e., the "green gap". DLOS studies of light emitting diodes (LEDs) identified QW defects whose concentration increased significantly with increasing x. The effect of increased QW defect density on IQE was assessed by examining the PL of MQW samples. Green-emitting MQWs had lower IQE and required higher pump power to reach peak IQE, corroborating the important impact of enhanced non-radiative recombination at defects.

TI MONITORING AND UNDERSTANDING CHANGES IN EXTREMES SO BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY LA English DT Article ID EXTRATROPICAL CYCLONE ACTIVITY; US EAST-COAST; WAVE HEIGHTS; WIND-SPEED; CLIMATE CONTROLS; GLOBAL TRENDS; UNITED-STATES; REANALYSIS; VARIABILITY; CIRCULATION AB This scientific assessment examines changes in three climate extremesextratropical storms, winds, and waveswith an emphasis on U.S. coastal regions during the cold season. There is moderate evidence of an increase in both extratropical storm frequency and intensity during the cold season in the Northern Hemisphere since 1950, with suggestive evidence of geographic shifts resulting in slight upward trends in offshore/coastal regions. There is also suggestive evidence of an increase in extreme winds (at least annually) over parts of the ocean since the early to mid-1980s, but the evidence over the U.S. land surface is inconclusive. Finally, there is moderate evidence of an increase in extreme waves in winter along the Pacific coast since the 1950s, but along other U.S. shorelines any tendencies are of modest magnitude compared with historical variability. The data for extratropical cyclones are considered to be of relatively high quality for trend detection, whereas the data for extreme winds and waves are judged to be of intermediate quality. In terms of physical causes leading to multidecadal changes, the level of understanding for both extratropical storms and extreme winds is considered to be relatively low, while that for extreme waves is judged to be intermediate. Since the ability to measure these changes with some confidence is relatively recent, understanding is expected to improve in the future for a variety of reasons, including increased periods of record and the development of climate reanalysis projects.

TI A Review of Thermal Co-Conversion of Coal and Biomass/Waste SO ENERGIES LA English DT Review DE coal; biomass; co-gasification; synergy; thermal conversion ID FLUIDIZED-BED COMBUSTION; LOW-RANK COALS; EFFECTIVE RADICAL TRANSFER; NITROGEN-OXIDE FORMATION; VICTORIAN BROWN-COAL; SHOCK-TUBE PYROLYSIS; N2O PRECURSORS NH3; FREE-FALL REACTOR; FLASH PYROLYSIS; HEATING-RATE AB Biomass is relatively cleaner than coal and is the only renewable carbon resource that can be directly converted into fuel. Biomass can significantly contribute to the world's energy needs if harnessed sustainably. However, there are also problems associated with the thermal conversion of biomass. This paper investigates and discusses issues associated with the thermal conversion of coal and biomass as a blend. Most notable topics reviewed are slagging and fouling caused by the relatively reactive alkali and alkaline earth compounds (K2O, Na2O and CaO) found in biomass ash. The alkali and alkaline earth metals (AAEM) present and dispersed in biomass fuels induce catalytic activity during co-conversion with coal. The catalytic activity is most noticeable when blended with high rank coals. The synergy during co-conversion is still controversial although it has been theorized that biomass acts like a hydrogen donor in liquefaction. Published literature also shows that coal and biomass exhibit different mechanisms, depending on the operating conditions, for the formation of nitrogen (N) and sulfur species. Utilization aspects of fly ash from blending coal and biomass are discussed. Recommendations are made on pretreatment options to increase the energy density of biomass fuels through pelletization, torrefaction and flash pyrolysis to reduce transportation costs.

TI An Injectable Apatite Permeable Reactive Barrier for In Situ Sr-90 Immobilization SO GROUND WATER MONITORING AND REMEDIATION LA English DT Article ID ZERO-VALENT IRON; CONTAMINATED GROUNDWATER; LEAD IMMOBILIZATION; REDOX MANIPULATION; HEAVY-METALS; HYDROXYAPATITE; SORPTION; URANIUM; REMEDIATION; PHOSPHATE AB An injectable permeable reactive barrier (PRB) technology was developed to sequester Sr-90 in groundwater through the in situ formation of calcium-phosphate mineral phases, specifically apatite that incorporates Sr-90 into the chemical structure. This injectable barrier technology extends the PRB concept to sites where groundwater contaminants are too deep or where site conditions otherwise preclude the application of more traditional trench-emplaced barriers. An integrated, multiscale development and testing approach was used that included laboratory bench-scale experiments, an initial pilot-scale field test, and the emplacement and evaluation of a 300-feet-long treatability-test-scale PRB. The apatite amendment formulation uses two separate precursor solutions, one containing a Ca-citrate complex and the other a Na-phosphate solution, to form apatite precipitate in situ. Citrate is needed to keep calcium in solution long enough to achieve a more uniform and areally extensive distribution of precipitate formation. In the summer of 2008, the apatite PRB technology was applied as a 91-m-long (300 feet) PRB on the down gradient edge of a Sr-90 plume beneath the Hanford Site in Washington State. The technology was deployed to reduce Sr-90 flux discharging to the Columbia River. Performance assessment monitoring data collected to date indicate that the barrier is meeting treatment objectives (i.e., 90% reduction in Sr-90 concentration). The average reduction in Sr-90 concentrations at four downgradient compliance monitoring locations was 95% relative to the high end of the baseline range approximately 1 year after treatment, and continues to meet remedial objectives more than 4 years after treatment.

TI Estimating the Impact of Vadose Zone Sources on Groundwater to Support Performance Assessment of Soil Vapor Extraction SO GROUND WATER MONITORING AND REMEDIATION LA English DT Article ID MASS FLUX; HYDRAULIC CONDUCTIVITY; CONTAMINANT VAPORS; POROUS-MEDIA; MODEL; WATER; INTRUSION; TRANSPORT; CLOSURE; NAPL AB Soil vapor extraction (SVE) is a prevalent remediation remedy for volatile organic compound (VOC) contaminants in the vadose zone. To support selection of an appropriate condition at which SVE may be terminated for site closure or for transition to another remedy, an evaluation is needed to determine whether vadose zone VOC contamination has been diminished sufficiently to keep groundwater concentrations below threshold values. A conceptual model for this evaluation was developed for VOC fate and transport from a vadose zone source to groundwater when vapor-phase diffusive transport is the dominant transport process. A numerical analysis showed that, for these conditions, the groundwater concentration is controlled by a limited set of parameters, including site-specific dimensions, vadose zone properties, and source characteristics. On the basis of these findings, a procedure was then developed for estimating groundwater concentrations using results from the three-dimensional multiphase transport simulations for a matrix of parameter value combinations and covering a range of potential site conditions. Interpolation and scaling processes are applied to estimate groundwater concentrations at compliance (monitoring) wells for specific site conditions of interest using the data from the simulation results. The interpolation and scaling methodology using these simulation results provides a far less computationally intensive alternative to site-specific three-dimensional multiphase site modeling, while still allowing for parameter sensitivity and uncertainty analyses. With iterative application, the approach can be used to consider the effect of a diminishing vadose zone source over time on future groundwater concentrations. This novel approach and related simulation results have been incorporated into a user-friendly Microsoft (R) Excel (R)-based spreadsheet tool entitled SVEET (Soil Vapor Extraction Endstate Tool), which has been made available to the public.

The introduction, sizes, concentrations, and distribution of those pre-existing flaws at any moment of time are a direct and cumulative consequence of any glass's manufacturing, packaging, handling, and service histories. A new, nondestructive "High Resolution Flaw Classification System" is under development that rapidly identifies, measures, and maps surface-located flaws on glass. Flaws smaller than 8x8 mu m are detectable and many square centimeters per second can be scanned. The potential mechanical response of that glass, with that quantified surface-flaw state at that moment of time, can then be predicted using the classical Griffith criterion.

Part I: Operational Sampling Strategies SO JOURNAL OF ATMOSPHERIC AND OCEANIC TECHNOLOGY LA English DT Article DE Cloud retrieval; Cloud tracking; cloud motion winds; Data processing; Radars; Radar observations ID RADIATION MEASUREMENT PROGRAM; CLIMATE RESEARCH FACILITY; ATMOSPHERIC RADIATION AB The acquisition of scanning cloud radars by the Atmospheric Radiation Measurement (ARM) program and research institutions around the world generates the need for developing operational scan strategies for cloud radars. Here, the first generation of sampling strategies for the scanning ARM cloud radars (SACRs) is presented. These scan strategies are designed to address the scientific objectives of ARM; however, they introduce an initial framework for operational scanning cloud radars. While the weather community uses scan strategies that are based on a sequence of scans at constant elevations, the SACR scan strategies are based on a sequence of scans at constant azimuth. This is attributed to the cloud geometrical properties, which are vastly different from the rain and snow shafts that are the primary targets of precipitation radars; the need to cover the cone of silence; and the scanning limitations of the SACRs. A cloud surveillance scan strategy is introduced that is based on a sequence of horizon-to-horizon range-height indicator (RHI) scans that sample the hemispherical sky (HS) every 30 degrees azimuth (HSRHI). The HSRHI scan strategy is complimented with a low-elevation plan position indicator (PPI) scan. The HSRHI and PPI are repeated every 30 min to provide a static view of the cloud conditions around the SACR location. Between the HSRHI and PPI scan strategies, other scan strategies are introduced depending on the cloud conditions. In the future, information about the atmospheric cloud state will be used in a closed-loop process to optimize the selection of the SACR scan strategy.

TI Scanning ARM Cloud Radars. Part II: Data Quality Control and Processing SO JOURNAL OF ATMOSPHERIC AND OCEANIC TECHNOLOGY LA English DT Article DE Algorithms; Cloud retrieval; Cloud tracking; cloud motion winds; Data processing; Radars; Radar observations ID DOPPLER-RADAR; OBJECTIVE DETERMINATION; RETURNS; AIR AB The scanning Atmospheric Radiation Measurement (ARM) Program cloud radars (SACRs) are the primary instruments for documenting the four-dimensional structure and evolution of clouds within a 20-30-km radius of the ARM fixed and mobile sites. Here, the postprocessing of the calibrated SACR measurements is discussed. First, a feature mask algorithm that objectively determines the presence of significant radar returns is described. The feature mask algorithm is based on the statistical properties of radar receiver noise. It accounts for atmospheric emission and is applicable even for SACR profiles with few or no signal-free range gates. Using the nearest-in-time atmospheric sounding, the SACR radar reflectivities are corrected for gaseous attenuation (water vapor and oxygen) using a line-by-line absorption model. Despite having a high pulse repetition frequency, the SACR has a narrow Nyquist velocity limit and thus Doppler velocity folding is commonly observed. An unfolding algorithm that makes use of a first guess for the true Doppler velocity using horizontal wind measurements from the nearest sounding is described. The retrieval of the horizontal wind profile from the hemispherical sky range-height indicator SACR scan observations and/or nearest sounding is described. The retrieved horizontal wind profile can be used to adaptively configure SACR scan strategies that depend on wind direction. Several remaining challenges are discussed, including the removal of insect and second-trip echoes. The described algorithms significantly enhance SACR data quality and constitute an important step toward the utilization of SACR measurements for cloud research.

However, the accuracy and cost-effectiveness of an MDO process is highly dependent on designers' ability to structure the optimization problem for specific challenges, particularly when specifying how building attributes and their associated geometry are configured for an optimization process. This research fills these gaps in MDO literature by developing a computer-aided design (CAD)-centric attribution methodology for multidisciplinary optimization environments (CAMMOE). CAMMOE enables designers to improve the accuracy of their optimization processes by helping them develop and analyze alternative spaces that are of just the right size and composition to meet their design intent. The writers demonstrate the potential power and generality of CAMMOE to enable designers to formulate MDO problems that can be executed efficiently and effectively with two industry case studies.

Elliptical Fourier analysis is used to quantify the clavicle outline shape from skeletons and postero-anterior antemortem chest radiographs to rank individuals in terms of metric distance. Similar to leading fingerprint identification systems, shortlists of the top matching candidates are extracted for subsequent human visual assessment. Two independent tests of the computerized system using 17 field-recovered skeletons and 409 chest radiographs demonstrate that true-positive matches are captured within the top 5% of the sample 75% of the time. These results are outstanding given the eroded state of some field-recovered skeletons and the faintness of the 1950's photofluorographs. These methods enhance the capability to resolve several hundred cold cases for which little circumstantial information exists and current DNA and dental record technologies cannot be applied.

The 4321 sites of intense shear in fast coronal hole origin plasma are analyzed. The proton temperature, the proton specific entropy, and the proton number density at the locations of the shears are compared with the same quantities in the plasmas adjacent to the shears. A very slight but statistically significant enhancement of the proton temperature is seen at the sites of the shears, but it is accompanied by a larger enhancement of the proton number density at the sites of the shears. Consequently, there is no enhancement of the proton specific entropy at the shear sites, indicating no production of entropy; hence, no evidence for plasma heating is found at the sites of the velocity shears. Since the shearing velocities have appreciable Mach numbers, the authors suggest that there can be a slight adiabatic compression of the plasma at the shear zones.

TI On the cause and extent of outer radiation belt losses during the 30 September 2012 dropout event SO JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS LA English DT Article ID GEOMAGNETIC STORMS; RELATIVISTIC ELECTRONS; LOSS MECHANISMS; MAGNETIC STORM; ACCELERATION; EVOLUTION; WAVES; RING; FLUX AB On 30 September 2012, a flux "dropout" occurred throughout Earth's outer electron radiation belt during the main phase of a strong geomagnetic storm. Using eight spacecraft from NASA's Time History of Events and Macroscale Interactions during Substorms (THEMIS) and Van Allen Probes missions and NOAA's Geostationary Operational Environmental Satellites constellation, we examined the full extent and timescales of the dropout based on particle energy, equatorial pitch angle, radial distance, and species. We calculated phase space densities of relativistic electrons, in adiabatic invariant coordinates, which revealed that loss processes during the dropout were >90% effective throughout the majority of the outer belt and the plasmapause played a key role in limiting the spatial extent of the dropout. THEMIS and the Van Allen Probes observed telltale signatures of loss due to magnetopause shadowing and subsequent outward radial transport, including similar loss of energetic ring current ions. However, Van Allen Probes observations suggest that another loss process played a role for multi-MeV electrons at lower L shells (L* 1 MeV electrons and energetic protons, SAMPEX >1 MeV electrons, and ground observations of band-limited Pc1-2 wave activity, we show that this sudden loss was consistent with pitch angle scattering by electromagnetic ion cyclotron waves in the dusk magnetic local time sector at 3300 nT, and energetic electron injections and whistler-mode chorus waves were observed throughout the inner magnetosphere for >12 h. After this period, Bz turned northward, and injections, chorus activity, and enhancements in PSD ceased. Overall, the outer belt was depleted by this storm. From the unprecedented level of observations available, we show direct evidence of the competitive nature of different wave-particle interactions controlling relativistic electron fluxes in the outer radiation belt.

TI Energy reconstruction methods in the IceCube neutrino telescope SO JOURNAL OF INSTRUMENTATION LA English DT Article DE Cherenkov detectors; dE/dx detectors; Neutrino detectors; Performance of High Energy Physics Detectors ID SOUTH-POLE; GLACIAL ICE; PERFORMANCE; DEPENDENCE; SYSTEM; MEDIA AB Accurate measurement of neutrino energies is essential to many of the scientific goals of large-volume neutrino telescopes. The fundamental observable in such detectors is the Cherenkov light produced by the transit through a medium of charged particles created in neutrino interactions. The amount of light emitted is proportional to the deposited energy, which is approximately equal to the neutrino energy for v(e) and v(mu) charged-current interactions and can be used to set a lower bound on neutrino energies and to measure neutrino spectra statistically in other channels. Here we describe methods and performance of reconstructing charged-particle energies and topologies from the observed Cherenkov light yield, including techniques to measure the energies of uncontained muon tracks, achieving average uncertainties in electromagnetic-equivalent deposited energy of similar to 15% above 10 TeV.

TI Description and commissioning of NEXT-MM prototype: first results from operation in a Xenon-Trimethylamine gas mixture SO JOURNAL OF INSTRUMENTATION LA English DT Article DE Time projection chambers; Particle tracking detectors (Gaseous detectors); Double-beta decay detectors ID MICROMEGAS; DETECTORS; READOUT AB A technical description of NEXT-MM and its commissioning and first performance is reported. Having an active volume of similar to 35 cm drift x 28 cm diameter, it constitutes the largest Micromegas-read TPC operated in Xenon ever constructed, made by a sectorial arrangement of the 4 largest single wafers manufactured with the Microbulk technique to date. It is equipped with a suitably pixelized readout and with a sufficiently large sensitive volume (similar to 23 l) so as to contain long (similar to 20 cm) electron tracks. First results obtained at 1 bar for Xenon and Trymethylamine (Xe-(2%) TMA) mixture are presented. The TPC can accurately reconstruct extended background tracks. An encouraging full-width half-maximum of 11.6% was obtained for similar to 29 keV gammas without resorting to any data post-processing.

TI Physics of fully depleted CCDs SO JOURNAL OF INSTRUMENTATION LA English DT Article DE Photon detectors for UV, visible and IR photons (solid-state) (PIN diodes, APDs, Si-PMTs, G-APDs, CCDs, EBCCDs, EMCCDs etc); Detectors for UV, visible and IR photons ID CHARGE-COUPLED-DEVICES; HIGH-RESISTIVITY SILICON; DRIFT DETECTORS; STRIATIONS; CRYSTALS; DIFFUSION; IMAGERS; THICK AB In this work we present simple, physics-based models for two effects that have been noted in the fully depleted CCDs that are presently used in the Dark Energy Survey Camera. The first effect is the observation that the point-spread function increases slightly with the signal level. This is explained by considering the effect on charge-carrier diffusion due to the reduction in the magnitude of the channel potential as collected signal charge acts to partially neutralize the fixed charge in the depleted channel. The resulting reduced voltage drop across the carrier drift region decreases the vertical electric field and increases the carrier transit time. The second effect is the observation of low-level, concentric ring patterns seen in uniformly illuminated images. This effect is shown to be most likely due to lateral deflection of charge during the transit of the photo-generated carriers to the potential wells as a result of lateral electric fields.

A 9 x 4.5cm(2) double drift gap detector was placed in front of the electromagnetic calorimeter and four 9 x 10cm(2) detectors on the ATLAS Small Wheel, the first station of the forward muon spectrometer. The one attached to the calorimeter was exposed to interaction rates of about 70kHz/cm(2) at L = 5 x 10(33) cm(-2)s(-1) two orders of magnitude higher than the rates in the Small Wheel. We present the results from performance studies carried out using data collected with these detectors and we also compare the currents drawn by the detector installed in front of the electromagnetic calorimeter with the luminosity measurement in ATLAS.

TI The performance of the LHCf detector for hadronic showers SO JOURNAL OF INSTRUMENTATION LA English DT Article DE Calorimeters; Neutron detectors (cold, thermal, fast neutrons) ID PROTON-PROTON COLLISIONS; PHOTON ENERGY-SPECTRA AB The Large Hadron Collider forward (LHCf) experiment has been designed to use the LHC to benchmark the hadronic interaction models used in cosmic-ray physics. It measures neutral particles emitted in the very forward region of the LHC p-p or p-N collisions. In this paper, the performances of the LHCf detectors for hadronic showers was studied with MC simulations and beam tests. The detection efficiency for neutrons varies from 70% to 80% above 500 GeV. The energy resolutions are about 40% and the position resolution is 0.1 to 1.3 mm depending on the incident energy for neutrons. The energy scale determined by the MC simulations and the validity of the MC simulations were examined using 350 GeV proton beams at the CERN-SPS.

Two possible origins for these repsonse variations have been suggested: either photometric response (quantum efficiency) or effective pixel area is modified in these regions. In the latter case source position and shape distortions would be expected in these regions, with consequent impact on astrometric and weak lensing measurements. As an experimental check to distinguish between the two effects and to gauge the magnitude of distortion, we performed a measurment scanning an artificial star image across the affected region of one device.

TI Measurement of ortho-positronium properties in liquid scintillators SO JOURNAL OF INSTRUMENTATION LA English DT Article DE Particle identification methods; Scintillators, scintillation and light emission processes (solid; gas and liquid scintillators); Neutrino detectors ID BOREXINO AB Pulse shape discrimination is a well-established technique for background rejection in liquid scintillator detectors. It is particularly effective in separating heavy particles from light particles, but not in distinguishing electrons from positrons. This inefficiency can be overtaken by exploiting the formation of ortho-positronium (o-Ps), which alters the time profile of light pulses induced by positrons. We characterized the o-Ps properties in the most commonly used liquid scintillators, i.e. PC, PXE, LAB, OIL and PC + PPO. In addition, we studied the effects of scintillator doping on the o-Ps properties for dopants used in neutrino-less double beta decay experiments (Nd and Te) and in anti-neutrino and neutron detection (Gd and Li respectively). We found that the o-Ps properties are similar in all the tested scintillators, with a lifetime around 3 ns and a formation probability of about 50%. This result indicates that an o-Ps-enhanced pulse shape discrimination can be applied in liquid scintillator detectors for neutrino and anti-neutrino detection and for neutrino-less double beta decay search.

If such a process will be observed, it will be a proof of the charged-lepton-flavor-violation (cLFV), otherwise Mu2e will set an upper limit of R-mu e < 6 x 10(-17) @ 90% C.L. (which represents an improvement by 3-4 order of magnitude over the existing limit). The Mu2e detector apparatus consists of a magnetic spectrometer, devoted to the measurement of the electrons momentum, and an electromagnetic calorimeter (EMC) which provides an independent measurement of the electron energy, time and position, used for validating or rejecting candidate tracks selected by the tracking system. In this paper, we describe the baseline project of the EMC and present results in terms of performances and R&D. C1 [Pezzullo, G.; Cervelli, F.] Univ Pisa, Dept Phys, I-56100 Pisa, Italy.

Mechanical and chemical complexity, long service lives, aging materials, and designs with small margins of safety are typical for space launch vehicle components including the engine. Furthermore, these components can be exposed to various flaws and damage during the manufacturing, assembly, or ground handling phase. In regard to the engine, its performance characteristics can be significantly affected by the degradation resulting from such flaws and damages, which, in turn, might lead to failure of the entire space mission. Any manufacturing/operational damage needs to be detected at the earliest stage possible, so that the required preventive measures can be implemented, and component readiness and reliability must be checked either during manufacturing or during field inspections. This review study lists such possible flaws/damages on rocket engine components. This information could be beneficial for determining and developing the efficient techniques for reliable nondestructive evaluation and structural health monitoring.

Often the dispersion relation and material properties are unknown, uncertain, or difficult to model due to material complexity and variability in material properties, geometry, and/or environment, thereby requiring in situ estimation. Two methods are presented for estimating guided wave dispersion curves (phase and group velocity) in a multimodal, multipath environment using a phased array. Phase and group velocities are estimated in situ on an aluminum and carbon fiber plate and compared to theoretical values. Scattering from plate boundaries is localized using the estimated phase and group velocity curves through beamforming and ranging via time of flight.

The objective of this article is to determine an optimal demarcation date, which is required to properly normalize active-sensing data collected and processed using disparate methods for the purpose of damage detection performance comparison. We propose that maximizing average damage detection performance with respect to a demarcation date would provide both an estimate of the true incipient damage onset date and the proper normalization enabling comparison of detection performance among the otherwise disparate data sets. This work focuses on the use of ultrasonic guided waves to detect incipient damage prior to the surfacing of a visible, catastrophic crack. The blade was instrumented with piezoelectric transducers, which were used in a pitch-catch mode over a range of excitation frequencies. With respect to specific excitation frequencies and transmission paths, higher excitation frequencies provided consistent detection results for paths along the rotor blade's carbon fiber spar cap, but performance fell off with increasing excitation frequency for paths not along the spar cap. Lower excitation frequencies provided consistent detection performance among all sensor paths.

The continent-continent collision zone between Arabia and Eurasia has been widely studied in this context, but several different viable geodynamic models exist to explain the uplift and deformation of the Anatolian Plateau and the Caucasus Mountains. We have imaged the uppermost mantle shear wave velocity structure of the East Anatolian-Caucasus region using surface wave tomography to better understand the regional tectonic activity since the onset of the collision between the Arabian and Eurasian Plates. Furthermore, we used our tomographic models to better understand the processes, which are responsible for the formation of the 2km high plateau and the widespread volcanism in eastern Turkey, as well as reactivation of deformation and deep seismicity in the eastern Greater Caucasus. Our model of regional upper mantle shear wave velocity structure supports subduction of the northern and southern branches of Neo-Tethys lithosphere between Eurasia and Gondwana and suggests a possible underthrusting of the Kura Basin lithosphere beneath the Greater Caucasus.

Objectives To test the effects of aging on the concentration of polycyclic aromatic hydrocarbons (PAHs), nicotine and tobacco-specific nitrosamines in cigarette smoke. Methods We generated sidestream and mainstream cigarette smoke with a smoking machine, diluted it with conditioned filtered air, and passed it through a 6 m(3) flow reactor with air exchange rates that matched normal residential air exchange rates. We tested the effects of 60min aging on the concentration of 16 PAHs, nicotine, cotinine and tobacco-specific nitrosamines. We also measured sorption and deposition of nicotine, cotinine and tobacco-specific nitrosamines on materials placed within the flow reactor. Results We observed mass losses of 62% for PAHs, 72%, for nicotine, 79% for N-nitrosonornicotine and 80% for 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). Extraction of cotton cloth exposed to smoke yielded nicotine and NNK. The ratio of NNK:nicotine on the exposed cloth was 10-fold higher than that in aerosol samples. Conclusions Our data suggest that the majority of the PAHs, nicotine, cotinine and tobacco-specific nitrosamines that are released during smoking in homes and public places deposit on room surfaces. These data give an estimate of the potential for accumulation of carcinogens in thirdhand cigarette smoke. Exposure to PAHs and tobacco-specific nitrosamines, through dermal absorption and inhalation of contaminated dust, may contribute to smoking-attributable morbidity and mortality.

Using theoretical analysis combined with simulations, a set of experiments has been designed to study such interactions. Near-field mapping from the simulations shows a strong interaction of localized surface plasmon resonances (LSPR) with a photonic resonance; together they explain the scattering phenomenon observed in our experiments carried out in the far field. We observed the shift of LSPR as the plasma frequency was varied, resulting in a modification of the spectral shape. Utilizing the high aspect ratios of the ITO nanorods, the LSPR strength can be turned on and off by the polarization of the incident light. C1 [Li, Shi-Qiang; Guo, Peijun; Buchholz, D.

Such catalysts exhibit an inherent complexity, particularly due to interactions with the support and the adsorbate molecules, which can be highly sensitive to environmental conditions such as pressure and temperature. Recent reports demonstrate that finite size effects such as negative thermal expansion and large bond length disorder are directly caused by these complex interactions. To uncover the atomistic features underlying the reaction mechanisms and kinetics of metal catalysts, experimental characterization must accommodate the challenging operation conditions of catalytic processes and provide insights into system attributes. The combined application of x-ray absorption spectroscopy (XAS) and transmission electron microscopy (TEM) for this type of investigations will be examined, and the individual strengths and limitations of these methods will be discussed. Furthermore, spatial and temporal heterogeneities that describe real catalytic systems and can hinder their investigation by either averaging (such as XAS) or local (such as TEM) techniques alone will be addressed by conjoined, multiscale, ab initio density functional theory/molecular dynamics modeling of metal catalysts that can both support and guide experimental studies. When taken together, a new analysis scheme emerges, in which different forms of structure and dynamics can be fully characterized by combining information obtained experimentally by in situ XAS and electron microscopy as well as theoretically via modeling.

One chamber was coated with titanium nitride (TiN) and one with amorphous silicon (a-Si) immediately following fabrication. The last chamber was first tested without any coating and then coated with a-Si following a series of heat treatments. The outgassing rate of each chamber was measured at room temperatures between 15 and 30 degrees C following bakes at temperatures between 90 and 400 degrees C. Measurements for bare steel showed a significant reduction in the outgassing rate by nearly a factor of 20 after a 400 degrees C heat treatment (3.5 x 10(-12) Torr L s(-1) cm(-2) prior to heat treatment, reduced to 1.7 x 10(-13) Torr L s(-1) cm(-2) following heat treatment). The chambers that were coated with a-Si showed minimal change in outgassing rates with heat treatment, though an outgassing rate reduced by heat treatments prior to a-Si coating was successfully preserved throughout a series of bakes. The TiN coated chamber exhibited remarkably low outgassing rates, up to four orders of magnitude lower than the uncoated stainless steel, but the uncertainty in these rates is large due to the sensitivity limitations of the spinning rotor gauge accumulation measurement and the possibility of a small pump speed due to inhomogeneity in the TiN coating. The outgassing results are discussed in terms of diffusion-limited versus recombination-limited processes. (C) 2014 American Vacuum Society.

Two procedures were utilized for film growth of similar to 15-30 ML thick films, where both procedures involved sequential deposition+oxidation cycles. In procedure 1, the iron oxide film was fully grown via sequential deposition+oxidation cycles, and then the fully grown film was exposed to a CO flux equivalent to 8 x 10(-7) millibars, and a vibrational spectrum of adsorbed CO was obtained using infrared reflection-absorption spectroscopy. The vibrational spectra of adsorbed CO from multiple preparations using procedure 1 show changes in the film termination structure and/or chemical nature of the surface defects-some of which are correlated with another phase that forms ("phase B"), even before enough of phase B has formed to be easily detected using low energy electron diffraction (LEED). During procedure 2, CO vibrational spectra were obtained between deposition+oxidation cycles, and these spectra show that the film termination structure and/or chemical nature of the surface defects changed as a function of sequential deposition+oxidation cycles. The authors conclude that measurement of vibrational spectra of adsorbed CO on oxide thin films provides a sensitive tool to probe chemical changes of defects on the surface and can thus complement LEED techniques by probing changes not visible by LEED. Increased use of vibrational spectra of adsorbed CO on thin films would enable better comparisons between films grown with different procedures and by different groups.

TI Reactive sputtering of substoichiometric Ta2Ox for resistive memory applications SO JOURNAL OF VACUUM SCIENCE & TECHNOLOGY A LA English DT Article ID TITANIUM-DIOXIDE; FILMS; DEPOSITION; NITRIDE; DEVICE; RRAM AB A major class of resistive memory devices is based on transition metal oxides, where mobile oxygen vacancies allow these devices to exhibit multiple resistance states. Ta2O5 based devices in particular have recently demonstrated impressive endurance and forming-free results. Deposition of substoichiometric Ta2Ox (x < 5) films is a critical process in order to produce the required oxygen vacancies in these devices. This paper describes a physical vapor deposition (PVD) reactive sputtering process to deposit substoichiometric Ta2Ox films. The desired film stoichiometry is achieved by feedback control of the oxygen partial pressure in the PVD chamber. A calibration procedure based on Rutherford backscattering spectroscopy is described for locating the optimum oxygen partial pressure. (C) 2014 American Vacuum Society.

TI Revealing the Bacterial Butyrate Synthesis Pathways by Analyzing (Meta) genomic Data SO MBIO LA English DT Article ID HUMAN LARGE-INTESTINE; ANAEROBIC-BACTERIA; CLOSTRIDIUM-ACETOBUTYLICUM; COA-TRANSFERASE; GUT MICROBIOTA; GENES; FERMENTATION; DEGRADATION; COENZYME; CONSERVATION AB Butyrate-producing bacteria have recently gained attention, since they are important for a healthy colon and when altered contribute to emerging diseases, such as ulcerative colitis and type II diabetes. This guild is polyphyletic and cannot be accurately detected by 16S rRNA gene sequencing. Consequently, approaches targeting the terminal genes of the main butyrate-producing pathway have been developed. However, since additional pathways exist and alternative, newly recognized enzymes catalyzing the terminal reaction have been described, previous investigations are often incomplete. We undertook a broad analysis of butyrate-producing pathways and individual genes by screening 3,184 sequenced bacterial genomes from the Integrated Microbial Genome database. Genomes of 225 bacteria with a potential to produce butyrate were identified, including many previously unknown candidates. The majority of candidates belong to distinct families within the Firmicutes, but members of nine other phyla, especially from Actinobacteria, Bacteroidetes, Fusobacteria, Proteobacteria, Spirochaetes, and Thermotogae, were also identified as potential butyrate producers. The established gene catalogue (3,055 entries) was used to screen for butyrate synthesis pathways in 15 metagenomes derived from stool samples of healthy individuals provided by the HMP (Human Microbiome Project) consortium. A high percentage of total genomes exhibited a butyrate-producing pathway (mean, 19.1%; range, 3.2% to 39.4%), where the acetyl-coenzyme A (CoA) pathway was the most prevalent (mean, 79.7% of all pathways), followed by the lysine pathway (mean, 11.2%). Diversity analysis for the acetyl-CoA pathway showed that the same few firmicute groups associated with several Lachnospiraceae and Ruminococcaceae were dominating in most individuals, whereas the other pathways were associated primarily with Bacteroidetes. IMPORTANCE Microbiome research has revealed new, important roles of our gut microbiota for maintaining health, but an understanding of effects of specific microbial functions on the host is in its infancy, partly because in-depth functional microbial analyses are rare and publicly available databases are often incomplete/misannotated. In this study, we focused on production of butyrate, the main energy source for colonocytes, which plays a critical role in health and disease. We have provided a complete database of genes from major known butyrate-producing pathways, using in-depth genomic analysis of publicly available genomes, filling an important gap to accurately assess the butyrate-producing potential of complex microbial communities from "-omics"-derived data. Furthermore, a reference data set containing the abundance and diversity of butyrate synthesis pathways from the healthy gut microbiota was established through a metagenomics-based assessment. This study will help in understanding the role of butyrate producers in health and disease and may assist the development of treatments for functional dysbiosis.

In quantum phase-changing materials (PCMs), microscopic charge, lattice, and orbital degrees of freedom interact cooperatively to modify macroscopic electrical and optical properties. Although these interactions are well documented for bulk single crystals and thin films, little is known about the ultrafast dynamics of nanostructured PCMs when interfaced to another class of materials as in this case to active plasmonic elements. Here, we demonstrate how a mesh of gold nanoparticles, acting as a plasmonic photocathode, induces an ultrafast phase transition in nanostructured vanadium dioxide (VO2) when illuminated by a spectrally resonant femtosecond laser pulse. Hot electrons created by optical excitation of the surface-plasmon resonance in the gold nanomesh are injected ballistically across the Au/VO2 interface to induce a subpicosecond phase transformation in VO2. Density functional calculations show that a critical density of injected electrons leads to a catastrophic collapse of the 6 THz phonon mode., which has been linked in different experiments to VO2 phase transition. The demonstration of subpicosecond phase transformations that are triggered by optically induced electron injection opens the possibility of designing hybrid nanostructures with unique nonequilibrium properties as a critical step for all-optical nanophotonic devices with optimizable switching thresholds.

Isolated, reactive defects were first introduced into the graphene lattice through ion bombardment and subsequently enlarged by oxidative etching into permeable pores with diameters of 0.40 +/- 0.24 nm and densities exceeding 10(12) cm(-2), while retaining structural integrity of the graphene. Transport measurements across ion-irradiated graphene membranes subjected to in situ etching revealed that the created pores were cation-selective at short oxidation times, consistent with electrostatic repulsion from negatively charged functional groups terminating the pore edges. At longer oxidation times, the pores allowed transport of salt but prevented the transport of a larger organic molecule, indicative of steric size exclusion. The ability to tune the selectivity of graphene through controlled generation of subnanometer pores addresses a significant challenge in the development of advanced nanoporous graphene membranes for nanofiltration, desalination, gas separation, and other applications.

One of the main issues for the transportation application is the need to develop high-performance cathode materials. Here we report a novel nanostructured cathode material based on air-stable polycrystalline Li0.28Co0.29Ni0.30Mn0.20O2 thin film with lithium deficiency for high-energy density lithium-ion batteries. This film is prepared via a method combining radio frequency magnetron sputtering and annealing using a crystalline and stoichiometric LiCo1/3Ni1/3Mn1/3O2 target. This lithium-deficient Li0.28Co0.29Ni0.30Mn0.20O2 thin film has a polycrystalline nanostructure, high tap density, and higher energy and power density compared to the initial stoichiometric LiCo1/3Ni1/3Mn1/3O2. Such a material is a promising cathode candidate for high-energy lithium-ion batteries, especially thin-film batteries.

In situ electrochemical fluid cells provide the ability to rapidly and directly characterize electrode/electrolyte interfacial reactions under conditions directly relevant to the operation of practical batteries. In this paper, we have studied the breakdown of a range of inorganic/salt complexes relevant to state-of-the-art Li-ion battery systems by in situ (scanning) transmission electron microscopy ((S)TEM). In these experiments, the electron beam itself caused the localized electrochemical reaction that allowed us to observe electrolyte breakdown in real-time. The results of the in situ (S)TEM experiments matches with previous stability tests performed during battery operation and the products and mechanisms are also consistent with known mechanisms. This analysis indicates that in situ liquid stage (S)TEM observations could be used to directly test new electrolyte designs and identify a smaller library of candidate solutions deserving of more detailed characterization. A systematic study of electrolyte degradation is also a necessary first step for any future controlled in operando liquid (S)TEM experiments intent on visualizing working batteries at the nanoscale.

Here, we demonstrate how an electronic structure characteristic of the isolated monolayer can be created at the surface of a bulk MoS2 crystal. This is achieved by intercalating potassium in the interlayer van der Waals gap, expanding its size while simultaneously doping electrons into the conduction band. Our angle-resolved photoemission measurements reveal resulting electron pockets centered at the (K) over bar and (K') over bar points of the Brillouin zone, providing the first momentum-resolved measurements of how the conduction band dispersions evolve to yield an approximately direct band gap of similar to 1.8 eV in quasi-freestanding monolayer MoS2. As well as validating previous theoretical proposals, this establishes a novel methodology for manipulating electronic structure in transition-metal dichalcogenides, opening a new route for the generation of large-area quasi-freestanding monolayers for future fundamental study and use in practical applications.

In particular, efficient hole contacts are required for the fabrication of p-type transistors with MoS2, a model TMDC. Previous studies have shown that the Fermi level of elemental metals is pinned close to the conduction band of MoS2, thus resulting in large Schottky barrier heights for holes with limited hole injection from the contacts. Here, we show that substoichiometric molybdenum trioxide (MoOx, x < 3), a high work function material, acts as an efficient hole injection layer to MoS2 and WSe2. In particular, we demonstrate MoS2 p-type field-effect transistors and diodes by using MoOx contacts. We also show drastic on-current improvement for p-type WSe2 FETs with MoOx contacts over devices made with Pd contacts, which is the prototypical metal used for hole injection. The work presents an important advance in contact engineering of TMDCs and will enable future exploration of their performance limits and intrinsic transport properties.

The MnAu clusters order into the L1(0) structure, and monotonic size-dependences develop for the composition and lattice parameters, which are well reproduced by our density functional theory calculations. Simultaneously, Mn diffusion forms 5 angstrom nanoshells on larger clusters inducing significant magnetization in an otherwise antiferromagnetic system. The differing atomic mobilities yield new cluster nanostructures that can be employed generally to create novel physical properties.

However, most previously demonstrated metasurface designs suffer from low coupling efficiency and are based on metallic resonators, leading to ohmic loss. Here, we present an alternative approach to plasmonic metasurfaces by replacing the metallic resonators with high-refractive-index silicon cut-wires in combination with a silver ground plane. We experimentally demonstrate that this meta-reflectarray can be used to realize linear polarization conversion with more than 98% conversion efficiency over a 200 nm bandwidth in the short-wavelength infrared band. We also demonstrate optical vortex beam generation using a meta-reflectarray with an azimuthally varied phase profile. The vortex beam generation is shown to have high efficiency over a wavelength range from 1500 to 1600 nm. The use of dielectric resonators in place of their plasmonic counterparts could pave the way for ultraefficient metasurface-based devices at high frequencies.

Molecular junctions that conduct through their highest occupied molecular orbital show a decrease in conductance when applying a positive electrochemical potential, and those that conduct though their lowest unoccupied molecular orbital show the opposite trend. We fit the experimentally measured conductance data as a function of gate voltage with a Lorentzian function and find the fitting parameters to be in quantitative agreement with self-energy corrected density functional theory calculations of transmission probability across single-molecule junctions. This work shows that electrochemical gating can directly modulate the alignment of the conducting orbital relative to the metal Fermi energy, thereby changing the junction transport properties.

A total of 14 modes were clearly resolved and identified, including fundamental modes of A, E and E-2 symmetries and their combinational modes involving two and three phonons. Through comparison with continuous wave Raman spectra as well as calculations based on an extended tight-binding model, we were able to identify all the observed peaks and determine the frequencies of the individual and combined modes. We provide a full summary of phonon frequencies for (6,5) nanotubes that can serve as a basic reference with which to refine our understanding of nanotube phonon spectra as well as a testbed for new theoretical models.

TI Extended Solid Solutions and Coherent Transformations in Nanoscale Olivine Cathodes SO NANO LETTERS LA English DT Article DE Lithium manganese iron phosphate; Li-ion batteries; in operando; X-ray diffraction; phase transformation; rate capability ID LITHIUM IRON PHOSPHATE; ELECTROCHEMICAL SHOCK; PHASE-TRANSFORMATION; BATTERY ELECTRODES; LIFEPO4 NANOPARTICLES; DIFFRACTION; KINETICS; CHARGE; LI-X(MNYFE1-Y)PO4; DEINTERCALATION AB Nanoparticle LiFePO4, the basis for an entire class of high power Li-ion batteries, has recently been shown to exist in binary lithiated/delithiated states at intermediate states of charge. The Mn-bearing version, LiMnyFe1-yPO4, exhibits even higher rate capability as a lithium battery cathode than LiFePO4 of comparable particle size. To gain insight into the cause(s) of this desirable performance, the electrochemically driven phase transformation during battery charge and discharge of nanoscale LiMn0.4Fe0.6PO4 of three different average particle sizes, 52, 106, and 152 nm, is investigated by operando synchrotron radiation powder X-ray diffraction. In stark contrast to the binary lithiation states of pure LiFePO4 revealed in recent investigations, the formations of metastable solid solutions covering a remarkable wide compositional range, including while in two-phase coexistence, are observed. Detailed analysis correlates this behavior with small elastic misfits between phases compared to either pure LiFePO4 or LiMnPO4. On the basis of time- and state-of-charge dependence of the olivine structure parameters, we propose a coherent transformation mechanism. These findings illustrate a second, completely different phase transformation mode for pure well-ordered nanoscale olivines compared to the well-studied case of LiFePO4. C1 [Ravnsbaek, D.

TI Controlling Graphene Ultrafast Hot Carrier Response from Metal-like to Semiconductor-like by Electrostatic Gating SO NANO LETTERS LA English DT Article DE Graphene; terahertz; hot carrier; pump-probe ID HIGH-QUALITY; TERAHERTZ; SPECTROSCOPY; FILMS AB We investigate the ultrafast terahertz response of electrostatically gated graphene upon optical excitation. We observe that the photoinduced terahertz absorption increases in charge neutral graphene but decreases in highly doped graphene. We show that this transition from semiconductor-like to metal-like response is unique for zero bandgap materials such as graphene. In charge neutral graphene photoexcited hot carriers effectively increase electron and hole densities and increase the conductivity. In highly doped graphene, however, photoexcitation does not change net conducting carrier concentration. Instead, it mainly increases electron scattering rate and reduce the conductivity.

In this work, we report a sodium-ion battery based on a carbon-coated Fe3O4 anode, Na[Ni0.25Fe0.5Mn0.25]O-2 layered cathode, and NaClO4 in fluoroethylene carbonate and ethyl methanesulfonate electrolyte. This unique battery system combines an intercalation cathode and a conversion anode, resulting in high capacity, high rate capability, thermal stability, and much improved cycle life. This performance suggests that our sodium-ion system is potentially promising power sources for promoting the substantial use of low-cost energy storage systems in the near future.

On either side of the bicrystal boundary, the films show square hysteresis loops and have dielectric permittivities of 456 and 576, with loss tangents of 0.010 and 0.015, respectively. Using piezoresponse force microscopy (PFM), a decrease in the nonlinear piezoelectric response is observed in the vicinity (720-820 nm) of the grain boundary. This region represents the width over which the extrinsic contributions to the piezoelectric response (e.g., those associated with the domain density/configuration and/or the domain wall mobility) are influenced by the presence of the grain boundary. Transmission electron microscope (TEM) images collected near and far from the grain boundary indicate a strong preference for (101)/((1) over bar 01) type domain walls at the grain boundary, whereas (011)/(0 (1) over bar1) and (101)/((1) over bar 01) are observed away from this region. It is proposed that the elastic strain field at the grain boundary interacts with the ferro-electric/elastic domain structure, stabilizing (101)/((1) over bar 01) rather than (011)/(0 (1) over bar1) type domain walls, which inhibits domain wall motion under applied field and decreases non-linearity.

V-substitution in the Li sites (Wykoff position 8a) is confirmed by VK-edge X-ray absorption spectroscopy and Rietveld refinement (Li0.995V0.005Ni0.5Mn1.5O4). V-doped LiNi0.5Mn1.5O4 delivered a reversible capacity of approximately 130 and 142mAhg(-1) at ambient and elevated temperature conditions, respectively. Furthermore, the Li0.995V0.005Ni0.5Mn1.5O4 phase rendered approximately 94% and 84% of initial capacity compared to approximately 85% and 3% for the LiNi0.5Mn1.5O4 phase after 100 cycles in ambient and elevated temperature conditions, respectively. The enhancements are mainly because of the suppression of Mn dissolution and unwanted side reaction with electrolyte counterpart, and to the increase in conductivity, improving the electrochemical profiles for the V-doped phase.

Design of this non-magnetic pressure cell focuses on in situ pressure tuning and measurement by means of a helium-filled bellows actuator and fiber-coupled ruby fluorescence spectroscopy, respectively. We demonstrate the utility of this pressure cell with ac susceptibility measurements of superconducting, ferromagnetic, and antiferromagnetic phase transitions to pressures exceeding 8 GPa. This cell provides an opportunity to probe charge and magnetic order continuously and with high resolution in the three-dimensional Magnetic Field-Pressure-Temperature parameter space.

TI Single photon energy dispersive x-ray diffraction SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID CRYSTAL-STRUCTURE; HIGH-PRESSURE; SCATTERING; DETECTORS; PLASMA; TARGET; RANGE AB With the pressure range accessible to laser driven compression experiments on solid material rising rapidly, new challenges in the diagnosis of samples in harsh laser environments are emerging. When driving to TPa pressures (conditions highly relevant to planetary interiors), traditional x-ray diffraction techniques are plagued by increased sources of background and noise, as well as a potential reduction in signal. In this paper we present a new diffraction diagnostic designed to record x-ray diffraction in low signal-to-noise environments. By utilising single photon counting techniques we demonstrate the ability to record diffraction patterns on nanosecond timescales, and subsequently separate, photon-by-photon, signal from background. In doing this, we mitigate many of the issues surrounding the use of high intensity lasers to drive samples to extremes of pressure, allowing for structural information to be obtained in a regime which is currently largely unexplored.

The photon source is based on the fourth harmonic generation of a near IR beam from a Ti: sapphire laser pumped by a CWgreen laser and tunable between 5.3 eV and 7 eV. The most important part of the set-up is a compact, vacuum enclosed fourth harmonic generator based on potassium beryllium fluoroborate crystals, grown hydrothermally in the US. This source can deliver a photon flux of over 1014 photon/s. We demonstrate that this energy range is sufficient to measure the kz dispersion in an iron arsenic high temperature superconductor, which was previously only possible at synchrotron facilities.

TI Monitoring plasma treatment of thin films by surface plasmon resonance SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID MAGNETIC TUNNEL-JUNCTIONS; BARRIERS AB We report the surface plasmon resonance (SPR) measurements during plasma treatment of thin films by an indigenously designed setup. From the measurements on Al (6.3 nm)/Ag (38 nm) bi-layer at a pressure of 0.02 mbar, the SPR position was found to be shifted by similar to 20 degrees after a plasma treatment of similar to 7 h. The formation of oxide layers during plasma oxidation was confirmed by glancing angle x-ray diffraction (GXRD) measurements. Combined analysis of GXRD and SPR data confirmed that while top Al layer enables controlling plasma oxidation of Ag, the setup enables monitoring the same. The setup designed is a first of its kind for in situ SPR studies where creation of low pressure is a prerequisite. (C) 2014 AIP Publishing LLC.

In this paper we present a search for neutrinos associated with sources other than the solar core, such as gamma-ray bursts and solar flares. We present a new method for looking for temporal coincidences between neutrino events and astrophysical bursts of widely varying intensity. No correlations were found between neutrinos detected in SNO and such astrophysical sources. (C) 2013 Elsevier B.V. All rights reserved. C1 [Beltran, B.; Habib, S.; Hallin, A.

While photoautotrophic biofilms have long been used for wastewater remediation, biofuel production represents a relatively new and under-represented focus area. However, the direct measurement and characterization of fundamental parameters required for industrial control are challenging due to biofilm heterogeneity. This study evaluated oxygenic photosynthesis and respiration on two distinct microalgal biofilms cultured using a novel rotating algal biofilm reactor operated at field-and laboratory-scales. Clear differences in oxygenic photosynthesis and respiration were observed based on different culturing conditions, microalgal composition, light intensity and nitrogen availability. The cultures were also evaluated as potential biofuel synthesis strategies. Nitrogen depletion was not found to have the same effect on lipid accumulation compared to traditional planktonic microalgal studies. Physiological characterizations of these microalgal biofilms identify fundamental parameters needed to understand and control process optimization. Published by Elsevier Ltd.

TI The Role of Ru and RuO2 in the Catalytic Transfer Hydrogenation of 5-Hydroxymethylfurfural for the Production of 2,5-Dimethylfuran SO CHEMCATCHEM LA English DT Article DE bifunctional catalyst; biomass; hydrogenation; ruthenium; ruthenium oxide ID LIQUID FUEL 2,5-DIMETHYLFURAN; TOTAL-ENERGY CALCULATIONS; MEERWEIN-PONNDORF-VERLEY; WAVE BASIS-SET; EFFICIENT PRODUCTION; PHASE HYDROGENATION; BETA ZEOLITE; REDUCTION; RUTHENIUM; BIOMASS AB We have previously shown that 2,5-dimethylfuran (DMF) can be produced selectively from 5-hydroxymethylfurfural in up to 80% yield via catalytic transfer hydrogenation with 2-propanol as a hydrogen donor and Ru/C as a catalyst. Herein, we investigate the active phase of the Ru/C catalyst by using extended X-ray absorption fine structure, X-ray photoelectron spectroscopy, and high-resolution TEM analyses. The results reveal that RuO2 is the dominant phase in the fresh (active) catalyst and is reduced to metallic Ru during the reaction with the hydrogen produced insitu from 2-propanol. The deactivation of the catalyst is correlated with the reduction of the surface of RuO2. Reactivity studies of individual phases (bulk RuO2 and reduced Ru/C catalysts) indicate that RuO2 mainly catalyzes the Meerwein-Ponndorf-Verley reaction of 5-hydroxymethylfurfural that produces 2,5-bis(hydroxymethyl)furan and the etherification of 2,5-bis(hydroxymethyl)furan or other intermediates with 2-propanol and that the reduced Ru/C catalyst has moderate hydrogenolysis activity for the production of DMF (30% selectivity) and other intermediates (20%). In contrast, a physical mixture of the two phases increases the DMF selectivity up to 70%, which suggests that both metallic Ru and RuO2 are active phases for the selective production of DMF. The oxidation of the reduced Ru/C catalyst at different temperatures and the insitu hydrogen titration of the oxidized Ru/C catalysts were performed to quantify the bifunctional role of Ru and RuO2 phases. The mild oxidation treatment of the Ru/C catalyst at 403K could activate the catalyst for the selective production of DMF in up to 72% yield by generating a partially oxidized Ru catalyst.

The population had been subjected to selection for increased number of ears per plant for 30 generations, with an empirically estimated effective population size ranging from 384 to 667 individuals and an increase of more than threefold in the number of ears per plant. Allele frequencies at >1.2 million single-nucleotide polymorphism loci were estimated from pooled whole-genome resequencing data, and F-ST values across sliding windows were employed to assess divergence between the population preselection and the population postselection. Twenty-eight highly divergent regions were identified, with half of these regions providing gene-level resolution on potentially selected variants. Approximately 93% of the divergent regions do not demonstrate a significant decrease in heterozygosity, which suggests that they are not approaching fixation. Also, most regions display a pattern consistent with a soft-sweep model as opposed to a hard-sweep model, suggesting that selection mostly operated on standing genetic variation. For at least 25% of the regions, results suggest that selection operated on variants located outside of currently annotated coding regions. These results provide insights into the underlying genetic effects of long-term artificial selection and identification of putative genetic elements underlying number of ears per plant in maize.

TI An Evaluation of High-Throughput Approaches to QTL Mapping in Saccharomyces cerevisiae SO GENETICS LA English DT Article DE QTL mapping; bulk segregant analysis; individual segregant analysis; next generation sequencing; yeast; reciprocal hemizygosity scanning ID QUANTITATIVE TRAIT LOCUS; GENETIC-BASIS; CONTROLLED EXPRESSION; ETHANOL TOLERANCE; DELETION MUTANTS; BUDDING YEAST; GENOME; IDENTIFICATION; ARCHITECTURE; RESOLUTION AB Dissecting the molecular basis of quantitative traits is a significant challenge and is essential for understanding complex diseases. Even in model organisms, precisely determining causative genes and their interactions has remained elusive, due in part to difficulty in narrowing intervals to single genes and in detecting epistasis or linked quantitative trait loci. These difficulties are exacerbated by limitations in experimental design, such as low numbers of analyzed individuals or of polymorphisms between parental genomes. We address these challenges by applying three independent high-throughput approaches for QTL mapping to map the genetic variants underlying 11 phenotypes in two genetically distant Saccharomyces cerevisiae strains, namely (1) individual analysis of >700 meiotic segregants, (2) bulk segregant analysis, and (3) reciprocal hemizygosity scanning, a new genome-wide method that we developed. We reveal differences in the performance of each approach and, by combining them, identify eight polymorphic genes that affect eight different phenotypes: colony shape, flocculation, growth on two nonfermentable carbon sources, and resistance to two drugs, salt, and high temperature. Our results demonstrate the power of individual segregant analysis to dissect QTL and address the underestimated contribution of interactions between variants. We also reveal confounding factors like mutations and aneuploidy in pooled approaches, providing valuable lessons for future designs of complex trait mapping studies.

Although both the mobility and threshold voltage degradations are more severe at 77 K than at 300 K for the same stress time, the temperature effect on the mobility degradation is larger than that on the threshold voltage degradation. In addition, the degradations of transistors with three different widths are compared after the stress tests at room and cryogenic temperatures, leading to the observation of degradation dependence on the transistor width. It is observed that the width dependence is more evident at 300 K, and the temperature plays a more significant role on the degradation for larger width transistors.

Understanding the mechanisms of CO2 migration and predicting its movement in shallow aquifers is a critical part of determining those impacts. During leakage, CO2 dissolved in brines may travel upward, potentially causing the gas to be released from solution (exsolve). Exsolved gas may accumulate at soil layer transitions, or flow into the vadose zone and ultimately the atmosphere. For this study, a series of intermediate-scale laboratory experiments were conducted to observe CO2 gas evolution in heterogeneous porous media. Results indicate that: (1) heterogeneous interfaces as well as flow constrictions through discontinuities in low-permeability layers enhance the evolution of gas phase, provided the water pressure at those layers is less than the pressure at which the flowing water was saturated with CO2, (2) higher contrast between the sands in a 1-D heterogeneous system leads to faster gas evolution, and (3) the effects of water flow rate on the evolution of the gas phase are sensitive to two-dimensional water flow pattern fluctuations.

This activity is part of a general assessment of the potential for safe CO2 injection into a sandstone reservoir (the Covey Hill Formation) within an Early Paleozoic sedimentary basin. Field and subsurface data are used to estimate the sealing properties of two reservoir-bounding faults (Yamaska and Champlain faults). The spatial variations in fluid pressure, effective minimum horizontal stress, and shear strain are calculated for different injection rates, using a simplified 2D geological model of the Becancour area, located similar to 110 km southwest of Quebec City. The simulation results show that initial fault permeability affects the timing, localization, rate, and length of fault shear slip. Contrary to the conventional view, our results suggest that shear failure may start earlier for a permeable fault than for a sealing fault, depending on the site-specific geologic setting. In simulations of a permeable fault, shear slip is nucleated along a 60 m long fault segment in a thin and brittle caprock unit (Utica Shale) trapped below a thicker and more ductile caprock unit (Lorraine Group) - and then subsequently progresses up to the surface. In the case of a sealing fault, shear failure occurs later in time and is localized along a fault segment (300 m) below the caprock units. The presence of the inclined low-permeable Yamaska Fault close to the injection well causes asymmetric fluid-pressure buildup and lateral migration of the CO2 plume away from the fault, reducing the overall risk of CO2 leakage along faults. Fluid-pressure-induced tensile fracturing occurs only under extremely high injection rates and is localized below the caprock units, which remain intact, preventing upward CO2 migration.

TI Experimental calibration of a numerical model describing the alteration of cement/caprock interfaces by carbonated brine SO INTERNATIONAL JOURNAL OF GREENHOUSE GAS CONTROL LA English DT Article DE Wellbore integrity; Carbon storage; Cement alteration; Core-flood experiments; Numerical modeling ID GEOLOGIC SEQUESTRATION CONDITIONS; H WELL CEMENT; CO2-RICH BRINE; CO2; DISSOLUTION; INTEGRITY; CAPROCK; EXPOSURE; SYSTEMS; ENERGY AB Deep wells provide a possible pathway for CO2 and brine leakage from geologic storage reservoirs to shallow groundwater resources and the atmosphere. The integrity of wellbore cement in these environments is of particular concern, because it is not known if changes in cement properties resulting from reaction with CO2-rich brines will lead to enhanced leakage over the life cycle of the storage reservoir. Assessment of wellbore leakage will ultimately be answered through models that capture both the chemical and physical processes and the uncertainty of key parameters within the wellbore environment. Towards this end, we use the results for 13 core-flood experiments conducted at variable partial pressures of CO2, flow rate, durations, and cement-caprock apertures to constrain a wellbore model that couples chemical processes important to assessing the long-term integrity of wellbore cements in geologic carbon storage environments. X-ray computed microtomography collected prior-to and following the experiments was employed to spatially resolve the interface and the extent of the reaction zones, and time dependent solution chemistry was used to track the chemical alteration over the course of the experiments. In this manuscript we focus on the development of geochemical model that describes the alteration of both the cement and the caprock. In our experiments, chemical alteration of the cement significantly exceeded any dissolution of carbonate minerals within the caprock and fracture geometry played no role on the extent of reaction. The experimental data was used to calibrate a numerical model of wellbore-caprock interfaces coupling reaction-front chemistry, fluid flow and transport of dissolved species. The geochemical model adopts an idealized representation of the cement chemistry in which appropriate equilibrium conditions are enforced at a series of discrete reaction fronts. The equilibrium conditions are coupled by diffusive transport between the fronts, which also determines the rate of front propagation. Despite its simplicity, the calibrated model accurately reproduces the reaction-zone growth and effluent chemistry for the range of experimental conditions considered and allowed key parameters to be confirmed or calibrated. These include the use of portlandite, calcite, and analcime solubility as equilibrium controls at specific reaction fronts within the cement; the use of constant effective diffusivity for each alteration zone; and diffusive growth of the alteration layers.

TI Numerical modeling of the pumping tests at the Ketzin pilot site for CO2 injection: Model calibration and heterogeneity effects SO INTERNATIONAL JOURNAL OF GREENHOUSE GAS CONTROL LA English DT Article DE Model calibration; Pumping test; Heterogeneity effect; CO2 arrival; Ketzin pilot site ID STUTTGART FORMATION; POROUS-MEDIA; GERMANY; STORAGE; CO2SINK; FLOW; RESERVOIR; SIMULATION; AQUIFERS; PROJECT AB Prior to injecting CO2 at the Ketzin pilot site for carbon storage near Berlin, Germany, several pumping tests were conducted in the three wells drilled for CO2 injection and monitoring. To characterize subsurface properties and help interpret the behavior of CO2 injected in the subsequent experiments, we calibrate a groundwater flow model for numerically simulating the pumping tests. The model honors the vertical layering of the storage formation: a sandstone layer of 6-18 m thickness embedded in a thick low-permeability mudstone (about 70-80 m). Model calibration involves estimating the spatial distribution of permeability in 13 zones for the sandstone layer while keeping the permeability of the mudstone at a fixed low value (1 x 10(-15) m(2)). The calibrated model produces system responses that are in good agreement with the measured pressure drawdown data, suggesting that the essential flow processes occurring during the pumping tests are well captured. The estimated permeability distribution indicates that heterogeneity is significant and that the pilot site acts as a semi-closed hydrogeologic system with one side effectively blocked by a low-permeability region. Of the three wells analyzed (Ktzi 200, Ktzi 201, and Ktzi 202), the inversion algorithm finds permeable zones connecting Ktzi 202 with Ktzi 200/Ktzi 201, while a low-permeability zone is found between Ktzi 201 and Ktzi 200. The calibrated results are consistent with the core logging and crosshole baseline ERT data and can help explain the migration of the CO2 plume, inferred from 3-D seismic surveys and ERT data obtained during the subsequent CO2 injection experiment. A proof-of-concept model shows that the presence of a low permeability zone between Ktzi 200 and Ktzi 201 is in fact consistent with the monitored CO2 arrival times at both wells if this zone of low effective permeability contains a thin high-permeability layer allowing for fast transport. Presence of a thin layer of high-permeability sandstone within a thick low-permeability layer does not significantly affect the pressure response in a pumping test as the effective permeability is still low, but it has a much larger impact on the CO2 arrival time by providing a preferential path for the CO2 migration.

In the case of geological sequestration of CO2, reactivation of faults may result in leakage pathways for the buoyant plume and thus compromise the integrity of seal formations. In this study, we investigate the potential for an overpressured reservoir formation to cause deformation and mechanical failure in an overlying, low-permeability caprock, thereby compromising seal integrity. In particular, we show that uplift and associated extensional strain in the caprock lead to a reduction in the minimum horizontal principal stress that reinforces the ambient extensional tectonic stress. Changes in the Coulomb failure stress (Delta CFS) characterize the tendency for fault failure. We use normalized and Delta CFS-weighted frequency distributions as an integrated measure of the 3-D distribution of Delta CFS. These measures quantify the magnitude and nature of the risk of induced seismicity. Using the example of the Springerville-St. Johns CO2 reservoir as an analogue site, we explore the sensitivity of the induced seismic risk to caprock stiffness, reservoir overpressure and well configuration. Over a range of these parameters, we calculate the geomechanical response of a large reservoir over a ten-year period of injection. The magnitude of induced stresses within the caprock is approximately 1-2 MPa for typical overpressures of 5-10 MPa, even in regions where the low-permeability caprock prevents appreciable increases in pore pressure. These stresses would be sufficient to cause reactivation of an undetected, well-oriented, critically stressed structure present above or near the injection location. Importantly, we show that this occurs outside a sphere of influence delineated by sub-surface pressure increase. (C) 2014 Elsevier Ltd. All rights reserved.

To simulate energy performance of such materials, it is important to have spectral data in the solar range, 300-2500 nm, for each temperature that the material will have in the simulation. This paper describes a temperature control strategy that allows for measurement of reflectance and transmittance at a fixed temperature using a commercial spectrophotometer. A specimen frame is used to clamp heating strips to the surface at the edge of the sample that is being tested. Multiple thermocouples are used to monitor the temperature gradient over the sample as the center is cooler than the edge. Verification using an infrared (IR) camera and time-resolved transmittance measurements show that the center sample temperature is stable and how long it takes to achieve equilibrium. An interpolation method is described and verified to reduce the number of states that need to be measured. A recommended test procedure is described and used on two different materials.

In this work, we present successive and concurrent in situ TEM dual-beam self-ion irradiation of 2.8 MeV Au4+ and implantation of 10 keV He1+, utilizing a new facility at Sandia National Laboratories. These experiments, using a model material system, provide direct real-time insight into initial interactions of displacement damage and fission products that simulate damage from neutron exposure. In successive irradiation, extensive dislocation loop and stacking fault tetrahedra damage was formed and could be associated with individual ion strikes, but no evidence of cavity formation was observed. In contrast, concurrent irradiation to the same dose resulted in the onset of cavity formation at the site of a heavy-ion strike. This direct real-time observation provides insight into the complex interplay between the helium and vacancy dynamics.

When irradiated to 5 dpa, experimental observations reveal the instantaneous formation and annihilation of point defect clusters, with such processes attributed to the long range elastic interactions that occur between defects through multiple intra-cascade overlap. Corresponding differences in the defect cluster density and size distribution suggest that changes to the microstructure were dependent upon temperature and dose, affecting the growth, accumulation and mobility of irradiation-induced defect clusters under these conditions.

The measured relaxation time was significantly longer than the alpha-relaxation time reported by dynamical mechanical analysis (DMA), indicating that these two relaxation processes are fundamentally different from each other. The temperature dependence of electrical resistivity suggests that the origin of the beta-relaxation process that occurs between room temperature and T-g may be the compositional short range ordering. Anomalous volume expansion was observed in the initial stage of relaxation, which was attributed to annihilation of the p-type defects with very short relaxation time.

Typical LP formulations, even strengthened by clique inequalities, yield poor bounds for this problem. We show that a strong bound can be obtained by the use of the so-called rank inequalities, which generalize the clique inequalities. For some problems the clique inequalities imply the rank inequalities, and then a strong bound is guaranteed already by the simpler formulation. (C) 2014 Elsevier B.V. All rights reserved.

TI A streamline splitting pore-network approach for computationally inexpensive and accurate simulation of transport in porous media SO WATER RESOURCES RESEARCH LA English DT Article DE modeling; pore networks; streamline splitting method (SSM); mixed cell method (MCM); pore-scale modeling; flow and transport; micromodel experiments ID DISPERSION; DIFFUSION; TRANSIENT; SOLUTE AB Several approaches have been developed in the literature for solving flow and transport at the pore scale. Some authors use a direct modeling approach where the fundamental flow and transport equations are solved on the actual pore-space geometry. Such direct modeling, while very accurate, comes at a great computational cost. Network models are computationally more efficient because the pore-space morphology is approximated. Typically, a mixed cell method (MCM) is employed for solving the flow and transport system which assumes pore-level perfect mixing. This assumption is invalid at moderate to high Peclet regimes. In this work, a novel Eulerian perspective on modeling flow and transport at the pore scale is developed. The new streamline splitting method (SSM) allows for circumventing the pore-level perfect-mixing assumption, while maintaining the computational efficiency of pore-network models. SSM was verified with direct simulations and validated against micromodel experiments; excellent matches were obtained across a wide range of pore-structure and fluid-flow parameters. The increase in the computational cost from MCM to SSM is shown to be minimal, while the accuracy of SSM is much higher than that of MCM and comparable to direct modeling approaches. Therefore, SSM can be regarded as an appropriate balance between incorporating detailed physics and controlling computational cost. The truly predictive capability of the model allows for the study of pore-level interactions of fluid flow and transport in different porous materials. In this paper, we apply SSM and MCM to study the effects of pore-level mixing on transverse dispersion in 3-D disordered granular media. Key Points Predictive method for simulating transport in pore networks developed Method validated with experiments and shown to be computationally inexpensive Mechanisms of transverse dispersion in 3-D granular porous media studied C1 [Mehmani, Yashar; Balhoff, Matthew T.] Univ Texas Austin, Dept Petr & Geosyst Engn, Austin, TX 78712 USA.

The GFMS uses real-time satellite-based precipitation to derive flood monitoring parameters for the latitude band 50 degrees N-50 degrees S at relatively high spatial (approximate to 12 km) and temporal (3 hourly) resolution. Examples of model results for recent flood events are computed using the real-time GFMS (). To evaluate the accuracy of the new GFMS, the DRIVE model is run retrospectively for 15 years using both research-quality and real-time satellite precipitation products. Evaluation results are slightly better for the research-quality input and significantly better for longer duration events (3 day events versus 1 day events). Basins with fewer dams tend to provide lower false alarm ratios. For events longer than three days in areas with few dams, the probability of detection is approximate to 0.9 and the false alarm ratio is approximate to 0.6. In general, these statistical results are better than those of the previous system. Streamflow was evaluated at 1121 river gauges across the quasi-global domain. Validation using real-time precipitation across the tropics (30 degrees S-30 degrees N) gives positive daily Nash-Sutcliffe Coefficients for 107 out of 375 (28%) stations with a mean of 0.19 and 51% of the same gauges at monthly scale with a mean of 0.33. There were poorer results in higher latitudes, probably due to larger errors in the satellite precipitation input.

TI Adsorption and capillary condensation in porous media as a function of the chemical potential of water in carbon dioxide SO WATER RESOURCES RESEARCH LA English DT Article DE chemical potential of water; supercritical CO2; augmented Young-Laplace equation; water film; partial saturation ID WET SUPERCRITICAL CO2; X-RAY-DIFFRACTION; SALT-PRECIPITATION; LIQUID RETENTION; SEQUESTRATION; FORSTERITE; STORAGE; PORE; TRANSPORT; CAPTURE AB The chemical potential of water may play an important role in adsorption and capillary condensation of water under multiphase conditions at geologic CO2 storage sites. Injection of large volumes of anhydrous CO2 will result in changing values of the chemical potential of water in the supercritical CO2 phase. We hypothesize that the chemical potential will at first reflect the low concentration of dissolved water in the dry CO2. As formation water dissolves into and is transported by the CO2 phase, the chemical potential of water will increase. We present a pore-scale model of the CO2-water interface or menisci configuration based on the augmented Young-Laplace equation, which combines adsorption on flat surfaces and capillary condensation in wedge-shaped pores as a function of chemical potential of water. The results suggest that, at a given chemical potential for triangular and square pores, liquid water saturation will be less in the CO2-water system under potential CO2 sequestration conditions relative to the air-water vadose zone system. The difference derives from lower surface tension of the CO2-water system and thinner liquid water films, important at pore sizes <1 x 10(-6) m, relative to the air-water system. Water movement due to capillary effects will likely be minimal in reservoir rocks, but still may be important in finer grained, clayey caprocks, where very small pores may retain water and draw water back into the system via adsorption and capillary condensation, if dry-out and then rewetting were to occur. Key Points We present water adsorption and capillary condensation for the carbon dioxide-water system Less water pore saturation for carbon dioxide storage sites than vadose zone Reservoir rocks require relatively high water activities for imbibition snap-off C1 [Heath, Jason E.; Dewers, Thomas A.] Sandia Natl Labs, Dept Geomech, Albuquerque, NM 87185 USA.

TI Patterns of root decomposition in response to soil moisture best explain high soil organic carbon heterogeneity within a mesic, restored prairie SO AGRICULTURE ECOSYSTEMS & ENVIRONMENT LA English DT Article DE Root biomass; Root distributions; Root production; Soil organic matter; Tallgrass prairie; Wisconsin, USA ID US GREAT-PLAINS; TALLGRASS PRAIRIE; LITTER DECOMPOSITION; CLIMATE-CHANGE; INTERANNUAL VARIABILITY; DEPTH DISTRIBUTION; REGIONAL PATTERNS; TEMPERATE STEPPE; FOOD SECURITY; NORTH-AMERICA AB Spatially heterogeneous patterns of soil organic carbon (SOC) are related to topographically-defined soil moisture levels within Midwestern tallgrass prairies. While roots are regarded as the main contributor to SOC formation, relatively little is known about how fine root dynamics respond to landscape-level changes in soil moisture, and thus the mechanisms promoting spatial heterogeneity of SOC remain uncertain. We evaluated SOC, fine root (<= 2 mm) biomass, production, decomposition, and vertical rooting distributions among landscape positions varying in soil moisture within 25+ year old restored tallgrass prairies in Wisconsin, USA. We hypothesized that SOC, root biomass, and root production would increase, while root decomposition would decline with increasing soil moisture. Additionally, we hypothesized that relative root biomass and production distributions would become shallower as soils became wetter. We found no relationship between soil moisture and root biomass, production, or their vertical distributions, but decomposition decreased and SOC increased as expected with increasing soil moisture. However, we also observed a strong relationship between soil moisture and species assemblages, suggesting that community composition changed in response to soil moisture. Our findings indicate that SOC was highest in seasonally wet, lowland landscape positions due to greatly reduced root decomposition, not due to changes in root production or relative distributions. We suggest that species turnover may have reduced the effect of soil moisture on root biomass and production, thereby maintaining similar root production under notably disparate soil moisture conditions. Considering continued interest in monoculture biofuel plantings and their potential to sequester C in roots and soils, additional research is necessary at the landscape scale to elucidate the importance of species spatial heterogeneity on grassland belowground C dynamics.

TI OBSERVATIONS OF THE UNIDENTIFIED GAMMA-RAY SOURCE TeV J2032+4130 BY VERITAS SO ASTROPHYSICAL JOURNAL LA English DT Article DE gamma rays: general; pulsars: individual (PSR J2032+4127) ID CYGNUS REGION; SOURCE TEV-J2032+4130; FOLLOW-UP; ASTRONOMY; TELESCOPE; POPULATION; SEPARATION; DISCOVERY; EMISSION; GALAXY AB TeV J2032+4130 was the first unidentified source discovered at very high energies (VHEs; E > 100 GeV), with no obvious counterpart in any other wavelength. It is also the first extended source to be observed in VHE gamma rays. Following its discovery, intensive observational campaigns have been carried out in all wavelengths in order to understand the nature of the object, which have met with limited success. We report here on a deep observation of TeV J2032+4130 based on 48.2 hr of data taken from 2009 to 2012 by the Very Energetic Radiation Imaging Telescope Array System experiment. The source is detected at 8.7 standard deviations (sigma) and is found to be extended and asymmetric with a width of 9'.5 +/- 1'.2 along the major axis and 4'.0 +/- 0'.5 along the minor axis. The spectrum is well described by a differential power law with an index of 2.10 +/- 0.14(stat) +/- 0.21(sys) and a normalization of (9.5 +/- 1.6(stat) +/- 2.2(sys)) x 10(-13) TeV-1 cm(-2) s(-1) at 1 TeV. We interpret these results in the context of multiwavelength scenarios which particularly favor the pulsar wind nebula interpretation.

TI BONDI-HOYLE ACCRETION IN AN ISOTHERMAL MAGNETIZED PLASMA SO ASTROPHYSICAL JOURNAL LA English DT Article DE ISM: magnetic fields; magnetohydrodynamics (MHD); stars: formation ID ADAPTIVE MESH REFINEMENT; STAR-FORMATION; LYTTLETON ACCRETION; SINK PARTICLES; MASSIVE STARS; BLACK-HOLES; HYDRODYNAMICS; RESOLUTION; CLOUDS; TURBULENCE AB In regions of star formation, protostars and newborn stars will accrete mass from their natal clouds. These clouds are threaded by magnetic fields with a strength characterized by the plasma beta-the ratio of thermal and magnetic pressures. Observations show that molecular clouds have beta less than or similar to 1, so magnetic fields have the potential to play a significant role in the accretion process. We have carried out a numerical study of the effect of large-scale magnetic fields on the rate of accretion onto a uniformly moving point particle from a uniform, non-self-gravitating, isothermal gas. We consider gas moving with sonic Mach numbers of up to M approximate to 45; magnetic fields that are either parallel, perpendicular, or oriented 45 degrees to the flow; and beta as low as 0.01. Our simulations utilize adaptive mesh refinement in order to obtain high spatial resolution where it is needed; this also allows the boundaries to be far from the accreting object to avoid unphysical effects arising from boundary conditions. Additionally, we show that our results are independent of our exact prescription for accreting mass in the sink particle. We give simple expressions for the steady-state accretion rate as a function of beta and M for the parallel and perpendicular orientations. Using typical molecular cloud values of M similar to 5 and beta similar to 0.04 from the literature, our fits suggest that a 0.4 M-circle dot star accretes similar to 4 x 10(-9) M-circle dot yr(-1), almost a factor of two less than accretion rates predicted by hydrodynamic models. This disparity can grow to orders of magnitude for stronger fields and lower Mach numbers. We also discuss the applicability of these accretion rates versus accretion rates expected from gravitational collapse, and under what conditions a steady state is possible. The reduction in the accretion rate in a magnetized medium leads to an increase in the time required to form stars in competitive accretion models, making such models less efficient than predicted by Bondi-Hoyle rates. Our results should find application in numerical codes, enabling accurate sub-grid models of sink particles accreting from magnetized media.

TI PROBING THE COSMIC GAMMA-RAY BURST RATE WITH TRIGGER SIMULATIONS OF THE SWIFT BURST ALERT TELESCOPE SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: star formation; gamma-ray burst: general; stars: formation ID STAR-FORMATION HISTORY; LUMINOSITY FUNCTION; REDSHIFT DISTRIBUTION; SPECTRAL EVOLUTION; COMPLETE SAMPLE; RESOLUTION SPECTROSCOPY; PEAK ENERGY; GRB 091127; LONG; SUPERNOVA AB The gamma-ray burst (GRB) rate is essential for revealing the connection between GRBs, supernovae, and stellar evolution. Additionally, the GRB rate at high redshift provides a strong probe of star formation history in the early universe. While hundreds of GRBs are observed by Swift, it remains difficult to determine the intrinsic GRB rate due to the complex trigger algorithm of Swift. Current studies of the GRB rate usually approximate the Swift trigger algorithm by a single detection threshold. However, unlike the previously flown GRB instruments, Swift has over 500 trigger criteria based on photon count rate and an additional image threshold for localization. To investigate possible systematic biases and explore the intrinsic GRB properties, we develop a program that is capable of simulating all the rate trigger criteria and mimicking the image threshold. Our simulations show that adopting the complex trigger algorithm of Swift increases the detection rate of dim bursts. As a result, our simulations suggest that bursts need to be dimmer than previously expected to avoid overproducing the number of detections and to match with Swift observations. Moreover, our results indicate that these dim bursts are more likely to be high redshift events than low-luminosity GRBs. This would imply an even higher cosmic GRB rate at large redshifts than previous expectations based on star formation rate measurements, unless other factors, such as the luminosity evolution, are taken into account. The GRB rate from our best result gives a total number of 4568(-1429)(+825) GRBs per year that are beamed toward us in the whole universe.

The system was operated with Avicel as the carbon source and either Clostridium thermocellum ATCC 27405 or a consortium enriched from compost as inocula. Multiple cycles of growth medium addition, incubation, and medium removal were performed with each inoculum. Removal and addition of media were automatically initiated when CO2 production fell to 90% of the cycle's peak. A strong correlation was observed between CO2 production and cellulose consumption, suggesting that the online signal was a good proxy for substrate utilization. Both cultures exhibited accelerated substrate utilization and a decrease in cycle time. About the same number of cycles was required to reach maximum CO2 production for both cultures. Notably, the magnitudes of the maximum CO2 production rate and cycle times were very similar for both C. thermocellum in pure culture and an environmental consortium. (C) 2013 Elsevier Ltd.

However, the major bottleneck in the strain screening process is that currently known methods for the estimation of microalgal lipid are laborious and time-consuming. The present study successfully employed sulpho-phospho-vanillin (SPV) colorimetric method for direct quantitative measurement of lipids within liquid microalgal culture. The SPV reacts with lipids to produce a distinct pink color, and its intensity can be quantified using spectrophotometric methods by measuring absorbance at 530 nm. This method was employed for a rapid quantification of intracellular lipid contents within Chlorella sp., Monoraphidium sp., Ettlia sp. and Nannochloropsis sp., all of which were found to have lipid contents ranging in between 10% and 30%. Subsequent analysis of the biomass using gas chromatography confirmed that our protocol is highly accurate (R-2 = 0.99). (C) 2013 Elsevier Ltd. All rights reserved.

As a result of the unreasonable price level, it is impossible to exploit fully the substitution elasticity among energy resources and there is a negative impact on achieving energy conservation and energy efficiency. This paper proposes an optimized mechanism for residential energy prices in China, which maximizes the total social surplus subject to some related constraints. Three types of energy pricing mechanisms are designed based on China's low-carbon targets and the optimization of residential energy price policies through the dynamic CGE model. Compared with the energy price linkage method, the results show that the market netback value mechanism has a greater impact on the total social surplus. In order to achieve further low-carbon targets, the proportion of second and third tier residents can be expanded, while the energy prices could be deregulated to some degree. In addition, considering residential affordability, the government may take into account different electricity pricing mechanisms for different tiers of residents. Electricity pricing for the first tier, the second tier and the third tier should be based respectively on cost, the integration of energy price linkage and the market netback value mechanism.

TI Development and application of a statistical methodology to evaluate the predictive accuracy of building energy baseline models SO ENERGY LA English DT Article DE Baseline model; Prediction; Measurement and verification; Energy savings; Performance accuracy; Whole-Building energy AB This paper documents the development and application of a general statistical methodology to assess the accuracy of baseline energy models, focusing on its application to M&V (measurement and verification) of whole-building energy savings. The methodology complements the principles addressed in resources such as ASHRAE Guideline 14 and the International Performance Measurement and Verification Protocol. It requires fitting a baseline model to data from a "training period" and using the model to predict total electricity consumption during a subsequent "prediction period." We illustrate the methodology by evaluating five baseline models using data from 29 buildings. The training period and prediction period were varied, and model predictions of daily, weekly, and monthly energy consumption were compared to meter data to determine model accuracy. Several metrics were used to characterize the accuracy of the predictions, and in some cases the best-performing model as judged by one metric was not the best performer when judged by another metric.

TI Held-Suarez simulations with the Community Atmosphere Model Spectral Element (CAM-SE) dynamical core: A global axial angular momentum analysis using Eulerian and floating Lagrangian vertical coordinates SO JOURNAL OF ADVANCES IN MODELING EARTH SYSTEMS LA English DT Article DE dynamical core; hyperviscosity; Galerkin methods; vertical discretization; spectral elements; angular momentum ID GENERAL-CIRCULATION MODEL; SHALLOW-WATER EQUATIONS; CONSERVATION; SCHEME; ENERGY AB In this paper, an analysis of the global AAM conservation properties of NCAR's Community Atmosphere Model Spectral Element (CAM-SE) dynamical core under Held-Suarez forcing is presented. It is shown that the spurious sources/sinks of AAM in CAM-SE are 3 orders of magnitude smaller than the parameterized (physical) sources/sinks. The effect on AAM conservation by changing various numerical aspects of the dynamical core (e.g., different vertical coordinates, reduced formal order of accuracy, increased dissipation, and decreased divergence damping) is investigated. In particular, it is noted that changing from Eulerian (hybrid-sigma) to floating Lagrangian vertical coordinates does not alter the global AAM conservation properties of CAM-SE.

We use six variations related to the treatment of the atmospheric composition, the calculation of aerosol indirect effects, and ocean model component. Specifically, we test the difference between atmospheric models that have noninteractive composition, where radiatively important aerosols and ozone are prescribed from precomputed decadal averages, and interactive versions where atmospheric chemistry and aerosols are calculated given decadally varying emissions. The impact of the first aerosol indirect effect on clouds is either specified using a simple tuning, or parameterized using a cloud microphysics scheme. We also use two dynamic ocean components: the Russell and HYbrid Coordinate Ocean Model (HYCOM) which differ significantly in their basic formulations and grid. Results are presented for the climatological means over the satellite era (1980-2004) taken from transient simulations starting from the preindustrial (1850) driven by estimates of appropriate forcings over the 20th Century. Differences in base climate and variability related to the choice of ocean model are large, indicating an important structural uncertainty. The impact of interactive atmospheric composition on the climatology is relatively small except in regions such as the lower stratosphere, where ozone plays an important role, and the tropics, where aerosol changes affect the hydrological cycle and cloud cover. While key improvements over previous versions of the model are evident, these are not uniform across all metrics.

In a case based on observations from the Indirect and Semi-Direct Aerosol Campaign (ISDAC), it is found that ice number concentration, N-i, exerts significant influence on the cloud structure. Increasing N-i leads to a substantial reduction in liquid water path (LWP), in agreement with earlier studies. In contrast to previous intercomparison studies, all models here use the same ice particle properties (i.e., mass-size, mass-fall speed, and mass-capacitance relationships) and a common radiation parameterization. The constrained setup exposes the importance of ice particle size distributions (PSDs) in influencing cloud evolution. A clear separation in LWP and IWP predicted by models with bin and bulk microphysical treatments is documented and attributed primarily to the assumed shape of ice PSD used in bulk schemes. Compared to the bin schemes that explicitly predict the PSD, schemes assuming exponential ice PSD underestimate ice growth by vapor deposition and overestimate mass-weighted fall speed leading to an underprediction of IWP by a factor of two in the considered case. Sensitivity tests indicate LWP and IWP are much closer to the bin model simulations when a modified shape factor which is similar to that predicted by bin model simulation is used in bulk scheme. These results demonstrate the importance of representation of ice PSD in determining the partitioning of liquid and ice and the longevity of mixed-phase clouds.

The E-ALD program consisted of 15 periods of 5 cycles of CdTe and 15 cycles of PbTe, grown on a 15 cycle PbTe pre-layer formed on 200 nm of Au vapor deposited on glass. The cycle used for CdTe nano-film formation involved ramped potentials, that is, the potentials used to deposit Cd and Te were incremented negatively for each of the first 20 cycles. After 20 cycle the potentials were held constant for all the remaining cycles, and resulted in a stoichiometric and homogeneous CdTe deposit, as shown by Electron Probe Microanalysis (EPMA). Peaks corresponding to the cubic phase of CdTe were observed in the XRD pattern of the CdTe, with the (1 1 1) dominant. Optical studies of the CdTe revealed a band gap of 1.5 eV. The PbTe/CdTe superlattice was formed using the period above fifteen times. Deposition potentials, current-time traces and elemental coverages are described. The superlattice was determined to be stoichiometric, as determined by EPMA. The superlattice X-ray diffraction pattern displayed satellite peaks on the (I I 1) peak, as symmetric shoulders, indicating a period of 11 nm, rather than the anticipated 6 nm.

While backgrounds of the xenon isotopes are short-lived, they are constantly replenished from activities dominated by the fission-based production of Mo-99 used for medical procedures. At present, one of the most critical locations on earth for the monitoring of nuclear explosions is the Korean peninsula where the Democratic People's Republic of Korea (DPRK) has announced that it conducted three nuclear tests between 2006 and 2013. This paper explores the backgrounds that would be caused by the medium to large scale production of Mo-99 in the region of the Korean peninsula. (C) 2013 Elsevier Ltd. All rights reserved.

The importance of basal water in controlling sliding is well established, with increased sliding generally related to high basal water pressure, but the details of the interactions between the ice and water systems has not received much study when there is coupling between the systems. Here we use coupled subglacial hydrology and ice dynamics models within the Community Ice Sheet Model to investigate feedbacks between the ice and water systems. The dominant feedback we find is negative: sliding over bedrock bumps opens additional cavity space, which lowers water pressure and, in turn, sliding. We also find two small positive feedbacks: basal melt increases through frictional heat during sliding, which raises water pressure, and strain softening of basal ice during localized speedup causes cavities to close more quickly and maintain higher water pressures. Our coupled modeling demonstrates that a sustained input of surface water to a distributed drainage system can lead to a speedup event that decays even in the absence of channelization, due to increased capacity of the system through opening of cavities, which is enhanced through the sliding-opening feedback. We find that the negative feedback resulting from sliding-opening is robust across a wide range of parameter values. However, our modeling also argues that subglacial channelization is required to terminate speedup events over timescales that are commensurate with observations of late summer slowdown on mountain glaciers.

We show that whenever a nonlinear equation admits solutions in terms of both Jacobi elliptic functions cn(x, m) and dn(x, m) with modulus m, then it also admits solutions in terms of their sum as well as difference. We have checked this in the case of several nonlinear equations such as the nonlinear Schrodinger equation, MKdV, a mixed KdV-MKdV system, a mixed quadratic-cubic nonlinear Schrodinger equation, the Ablowitz-Ladik equation, the saturable nonlinear Schrodinger equation, lambda phi(4), the discrete MKdV as well as for several coupled field equations. Further, for a large number of nonlinear equations, we show that whenever a nonlinear equation admits a periodic solution in terms of dn(2)(x, m), it also admits solutions in terms of dn(2)(x, m) +/- root mcn(x, m)dn(x, m), even though cn(x, m)dn(x, m) is not a solution of these nonlinear equations. Finally, we also obtain superposed solutions of various forms for several coupled nonlinear equations. (C) 2014 AIP Publishing LLC. C1 [Khare, Avinash] IISER, Pune 411021, Maharashtra, India.

In layered compounds, such as La2-xSrxNiO4 and La2-xBaxCuO4, the doped charge carriers can segregate into periodically spaced charge stripes separating narrow domains of antiferromagnetic order. Although there have been theoretical proposals of dynamically fluctuating stripes, direct spectroscopic evidence of charge-stripe fluctuations has been lacking. Here we report the detection of critical lattice fluctuations, driven by charge-stripe correlations, in La2-xSrxNiO4 using inelastic neutron scattering. This scattering is detected at large momentum transfers where the magnetic form factor suppresses the spin fluctuation signal. The lattice fluctuations associated with the dynamic charge stripes are narrow in q and broad in energy. They are strongest near the charge-stripe melting temperature. Our results open the way towards the quantitative theory of dynamic stripes and for directly detecting dynamical charge stripes in other strongly correlated systems, including high-temperature superconductors such as La2-xSrxCuO4.

The prediction apparently contradicts state-of-the-art experimentally established phase diagrams overwhelmingly dominated by molecular phases. Here we present experimental evidence that the threshold pressure of similar to 120 GPa induces in molecular ammonia the process of autoionization to yet experimentally unknown ionic compound-ammonium amide. Our supplementary theoretical simulations provide valuable insight into the mechanism of autoionization showing no hydrogen bond symmetrization along the transformation path, a remarkably small energy barrier between competing phases and the impact of structural rearrangement contribution on the overall conversion rate. This discovery is bridging theory and experiment thus opening new possibilities for studying molecular interactions in hydrogen-bonded systems. Experimental knowledge on this novel ionic phase of ammonia also provides strong motivation for reconsideration of the theory of molecular ice layers formation and dynamics in giant gas planets.

TI On the damping effect of gas rarefaction on propagation of acoustic waves in a microchannel SO PHYSICS OF FLUIDS LA English DT Article ID SIMULATION MONTE-CARLO; RAREFIED-GAS; SOUND-PROPAGATION; BOLTZMANN-EQUATION; MONATOMIC GASES; REFLECTION AB We consider the response of a gas in a microchannel to instantaneous (small-amplitude) non-periodic motion of its boundaries in the normal direction. The problem is formulated for an ideal monatomic gas using the Bhatnagar, Gross, and Krook (BGK) kinetic model, and solved for the entire range of Knudsen (Kn) numbers. Analysis combines analytical (collisionless and continuum-limit) solutions with numerical (low-variance Monte Carlo and linearized BGK) calculations. Gas flow, driven by motion of the boundaries, consists of a sequence of propagating and reflected pressure waves, decaying in time towards a final equilibrium state. Gas rarefaction is shown to have a "damping effect" on equilibration process, with the time required for equilibrium shortening with increasing Kn. Oscillations in hydrodynamic quantities, characterizing gas response in the continuum limit, vanish in collisionless conditions. The effect of having two moving boundaries, compared to only one considered in previous studies of time-periodic systems, is investigated. Comparison between analytical and numerical solutions indicates that the collisionless description predicts the system behavior exceptionally well for all systems of the size of the mean free path and somewhat larger, in cases where boundary actuation acts along times shorter than the ballistic time scale. The continuum-limit solution, however, should be considered with care at early times near the location of acoustic wavefronts, where relatively sharp flow-field variations result in effective increase in the value of local Knudsen number.

In this paper, we present an experimental and computational study of droplet velocities and internal flow patterns in a rectangular pressure-driven flow for droplet diameters ranging from 0.1 to 2 times the channel height. Our study shows excellent agreement with asymptotic predictions of droplet and interfacial velocities for infinitesimally small droplets. As the droplet diameter nears the size of the channel height, the droplet velocity slows significantly, and the changing external flow field causes a qualitative change in the location of internal vortices. This behavior is relevant for future studies of mass transfer in microfluidic devices. (C) 2014 AIP Publishing LLC.

TI Holocene rockfalls in the southern Negev Desert, Israel and their relation to Dead Sea fault earthquakes SO QUATERNARY RESEARCH LA English DT Article DE Rockfalls; Cosmogenic nuclides; Exposure age dating; Dead Sea fault earthquakes ID COSMOGENIC NUCLIDE PRODUCTION; REGENERATIVE-DOSE PROTOCOL; IN-SITU; PRODUCTION-RATES; EROSION RATES; ARAVA VALLEY; EXPOSURE AGES; COSMIC-RAYS; ROCK FALLS; BE-10 AB Rockfall ages in tectonically active regions provide information regarding frequency and magnitude of earthquakes. In the hyper-arid environment of the Dead Sea fault (DSF), southern Israel, rockfalls are most probably triggered by earthquakes. We dated rockfalls along the western margin of the DSF using terrestrial cosmogenic nuclides (TCN). At each rockfall site, samples were collected from simultaneously exposed conjugate boulders and cliff surfaces. Such conjugate samples initially had identical pre-fall ("inherited") TCN concentrations. After boulder detachment, these surfaces were dosed by different production rates due to differences in post-fall shielding and geometry. However, in our study area, pre-rockfall inheritance and post-rockfall production rates of TCN cannot be evaluated. Therefore, we developed a numerical approach and demonstrated a way to overcome the above-mentioned problems. This approach can be applied in other settings where rockfalls cannot be dated by simple exposure dating. Results suggest rockfall ages between 3.6 +/- 0.8 and 4.7 +/- 0.7 ka. OSL ages of sediment accumulated behind the boulders range between 0.6 +/- 0.1 and 3.4 +/- 1.4 ka and support the TCN results. Our ages agree with dated earthquakes determined in paleoseismic studies along the entire length of the DSF and support the observation of intensive earthquake activity around 4-5 ka.

With simultaneous recordings of the three components of wave electric field E and of the three components of wave magnetic field B, the entire wavefield, polarization, and wave vector can be specified without any appeal to a priori assumptions about the wave mode and without any reliance on the validity of a dispersion relation. However, some satellites lack such a complete suite of measurements. We develop a method which assumes the theoretical dispersion relation for whistler waves then uses recordings of the three components of wave electric field E but no magnetic components to derive the wave polarization and the wave vector (up to a sign ambiguity on the latter). The method can work only because the dispersion relation, which is assumed, already contains information from the full Maxwell's equations. We illustrate the method with 12s duration simultaneous recordings, at 32kilosample/s, of three orthogonal components of wave electric field E from the C/NOFS satellite in low-Earth orbit. Our particular example in this article is shown to contain two broadband whistler features in the range of 4-15kHz, whose wave vectors differ both according to their polar angles from the geomagnetic field B-0 and according to their azimuth around the geomagnetic field B-0.

We calculate the total energy and magneto-anisotropy energy (MAE) versus (a, c) using DFT+U methods. We reproduce and explain all the above anomalies. We predict that coercivity and MAE increase due to increasing a, suggesting means to improve MnBi permanent magnets. (C) 2014 Author(s). C1 [Zarkevich, N. A.; Wang, L. -L.; Johnson, D.

Saccharomyces spp. can efficiently convert glucose to ethanol; however, xylose conversion to ethanol is a major hurdle due to lack of xylose-metabolizing pathways. In this study, a novel two-stage fermentation process was investigated to improve bioethanol productivity. In this process, xylose is converted into biomass via non-Saccharomyces microorganism and coupled to a glucose-utilizing Saccharomyces fermentation. Escherichia coli was determined to efficiently convert xylose to biomass, which was then killed to produce E. coli extract. Since earlier studies with Saccharomyces pastorianus demonstrated that xylose isomerase increased ethanol productivities on pure sugars, the addition of both E. coli extract and xylose isomerase to S. pastorianus fermentations on pure sugars and corn stover hydrolysates were investigated. It was determined that the xylose isomerase addition increased ethanol productivities on pure sugars but was not as effective alone on the corn stover hydrolysates. It was observed that the E. coli extract addition increased ethanol productivities on both corn stover hydrolysates and pure sugars. The ethanol productivities observed on the corn stover hydrolysates with the E. coli extract addition was the same as observed on pure sugars with both E. coli extract and xylose isomerase additions. These results indicate that the two-stage fermentation process has the capability to be a competitive alternative to recombinant Saccharomyces cerevisiae-based fermentations.

Despite efforts to reclaim and recycle IL from pretreated biomass, residual IL can be inhibitory to microorganisms used for downstream fermentation. As a result, pathways for IL tolerance are needed to improve the activity of fermentative organisms in the presence of IL. In this study, microbial communities from compost were cultured under high-solids and thermophilic conditions in the presence of 1-ethyl-3-methylimidazolium-based ILs to enrich for IL-tolerant microorganisms. A strain of Bacillus coagulans isolated from an IL-tolerant community was grown in liquid and solid-state culture in the presence of the ILs 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]) or 1-ethyl-3-methylimidazolium chloride ([C2mim][Cl]) to gauge IL tolerance. Viability and respiration varied with the concentration of IL applied and the type of IL used. B. coagulans maintained growth and respiration in the presence of 4 wt% IL, a concentration similar to that present on IL-pretreated biomass. In the presence of both [C2mim][OAc] and [C2mim][Cl] in liquid culture, B. coagulans grew at a rate approximately half that observed in the absence of IL. However, in solid-state culture, the bacteria were significantly more tolerant to [C2mim][Cl] compared with [C2mim][OAc]. B. coagulans tolerance to IL under industrially relevant conditions makes it a promising bacterium for understanding mechanisms of IL tolerance and discovering IL tolerance pathways for use in other microorganisms, particularly those used in bioconversion of IL-pretreated plant biomass.

TI Tropical forest carbon balance: effects of field-and satellite-based mortality regimes on the dynamics and the spatial structure of Central Amazon forest biomass SO ENVIRONMENTAL RESEARCH LETTERS LA English DT Article DE Amazon; biomass; forest; mortality; power law ID POWER-LAW DISTRIBUTIONS; DISTURBANCE AB Debate continues over the adequacy of existing field plots to sufficiently capture Amazon forest dynamics to estimate regional forest carbon balance. Tree mortality dynamics are particularly uncertain due to the difficulty of observing large, infrequent disturbances. A recent paper (Chambers et al 2013 Proc. Natl Acad. Sci. 110 3949-54) reported that Central Amazon plots missed 9-17% of tree mortality, and here we address `why' by elucidating two distinct mortality components: (1) variation in annual landscape-scale average mortality and (2) the frequency distribution of the size of clustered mortality events. Using a stochastic-empirical tree growth model we show that a power law distribution of event size (based on merged plot and satellite data) is required to generate spatial clustering of mortality that is consistent with forest gap observations. We conclude that existing plots do not sufficiently capture losses because their placement, size, and longevity assume spatially random mortality, while mortality is actually distributed among differently sized events (clusters of dead trees) that determine the spatial structure of forest canopies.

Successful phenomenology suggests that the glasma evolves rather quickly toward the thermal quark-gluon plasma (QGP) and a hydrodynamic behavior emerges at a very early time similar to(o) over cap (1) fm/c. Exactly how such "apparent thermalization" occurs and connects the initial conditions to the hydrodynamic onset, remains a significant challenge for theory as well as phenomenology. We briefly review various ideas and recent progress in understanding the approach of the glasma to the thermalized QGP, with an emphasis on the kinetic theory description for the evolution of such far-from-equilibrium and highly overpopulated, thus weakly-coupled yet strongly interacting glasma.

TI Dynamics of lysozyme and its hydration water under an electric field SO JOURNAL OF BIOLOGICAL PHYSICS LA English DT Article DE Quasi-elastic neutron scattering; Protein dynamics; Electric field; Diffusion ID NEUTRON-SCATTERING; PROTEIN; CONFORMATION; RELAXATION; CRYSTALS AB The effects of a static electric field on the dynamics of lysozyme and its hydration water are investigated by means of incoherent quasi-elastic neutron scattering (QENS). Measurements were performed on lysozyme samples, hydrated respectively with heavy water (D O-2) to capture the protein dynamics and with light water (H O-2), to probe the dynamics of the hydration shell, in the temperature range from 210 < T < 260 K. The hydration fraction in both cases was about similar to 0.38 gram of water per gram of dry protein. The field strengths investigated were respectively 0 kV/mm and 2 kV/mm ( similar to 2 x 10 (6) V/m) for the protein hydrated with D O-2 and 0 kV and 1 kV/mm for the H O-2-hydrated counterpart. While the overall internal protons dynamics of the protein appears to be unaffected by the application of an electric field up to 2 kV/mm, likely due to the stronger intra-molecular interactions, there is also no appreciable quantitative enhancement of the diffusive dynamics of the hydration water, as would be anticipated based on our recent observations in water confined in silica pores under field values of 2.5 kV/mm. This may be due to the difference in surface interactions between water and the two adsorption hosts (silica and protein), or to the existence of a critical threshold field value E (c) similar to 2-3 kV/mm for increased molecular diffusion, for which electrical breakdown is a limitation for our sample.

A sophisticated group cohomology approach has been used to classify bosonic symmetry-protected topological phases, which however does not transparently predict their properties. Here we provide a physical picture that leads to an intuitive understanding of a large class of symmetry-protected topological phases in d=1,2,3 dimensions. Such a picture allows us to construct explicit models for the symmetry-protected topological phases, write down ground state wave function and discover topological properties of symmetry defects both in the bulk and on the edge of the system. We consider symmetries that include a Z(2) subgroup, which allows us to define domain walls. While the usual disordered phase is obtained by proliferating domain walls, we show that symmetry-protected topological phases are realized when these domain walls are decorated, that is, are themselves symmetry-protected topological phases in one lower dimension. This construction works both for unitary Z(2) and anti-unitary time reversal symmetry. C1 [Chen, Xie; Lu, Yuan-Ming; Vishwanath, Ashvin] Univ Calif Berkeley, Dept Phys, Berkeley, CA 94720 USA.

TI Electric control of magnetism at the Fe/BaTiO3 interface SO NATURE COMMUNICATIONS LA English DT Article ID TUNNEL-JUNCTIONS; ROOM-TEMPERATURE; EXCHANGE BIAS; ATOMIC LAYERS; NANOSTRUCTURES; FERROELECTRICITY; MULTIFERROICS; OXIDES; IRON AB Interfacial magnetoelectric coupling is a viable path to achieve electrical writing of magnetic information in spintronic devices. For the prototypical Fe/BaTiO3 system, only tiny changes of the interfacial Fe magnetic moment upon reversal of the BaTiO3 dielectric polarization have been predicted so far. Here, by using X-ray magnetic circular dichroism in combination with high-resolution electron microscopy and first principles calculations, we report on an undisclosed physical mechanism for interfacial magnetoelectric coupling in the Fe/BaTiO3 system. At this interface, an ultrathin oxidized iron layer exists, whose magnetization can be electrically and reversibly switched on and off at room temperature by reversing the BaTiO3 polarization. The suppression/recovery of interfacial ferromagnetism results from the asymmetric effect that ionic displacements in BaTiO3 produces on the exchange coupling constants in the interfacial-oxidized Fe layer. The observed giant magnetoelectric response holds potential for optimizing interfacial magnetoelectric coupling in view of efficient, low-power spintronic devices.

TI An auto-inducible mechanism for ionic liquid resistance in microbial biofuel production SO NATURE COMMUNICATIONS LA English DT Article ID ESCHERICHIA-COLI; ENTEROBACTER-LIGNOLYTICUS; BIOMASS; PRETREATMENT; EFFLUX; GROWTH; BIOLOGY; SYSTEMS; PROTEIN; YEAST AB Ionic liquids (ILs) are emerging as superior solvents for numerous industrial applications, including the pretreatment of biomass for the microbial production of biofuels. However, some of the most effective ILs used to solubilize cellulose inhibit microbial growth, decreasing efficiency in the overall process. Here we identify an IL-resistance mechanism consisting of two adjacent genes from Enterobacter lignolyticus, a rain forest soil bacterium that is tolerant to an imidazolium-based IL. These genes retain their full functionality when transferred to an Escherichia coli biofuel host, with IL resistance established by an inner membrane transporter, regulated by an IL-inducible repressor. Expression of the transporter is dynamically adjusted in direct response to IL, enabling growth and biofuel production at levels of IL that are toxic to native strains. This natural auto-regulatory system provides the basis for engineering IL-tolerant microbes, which should accelerate progress towards effective conversion of lignocellulosic biomass to fuels and renewable chemicals.

However, carbon coating provides a strong reducing atmosphere and many factors remain unclear concerning the interface nature and underlying interaction mechanism that occurs between carbon and the active materials. Here, we present a size-dependent surface phase change occurring in lithium iron phosphate during the carbon coating process. Intriguingly, nanoscale particles exhibit an extremely high stability during the carbon coating process, whereas microscale particles display a direct visualization of surface phase changes occurring at the interface at elevated temperatures. Our findings provide a comprehensive understanding of the effect of particle size during carbon coating and the interface interaction that occurs on carbon-coated battery material-allowing for further improvement in materials synthesis and manufacturing processes for advanced battery materials.

TI Superconducting graphene sheets in CaC6 enabled by phonon-mediated interband interactions SO NATURE COMMUNICATIONS LA English DT Article ID ANGLE-RESOLVED PHOTOEMISSION; ELECTRONIC-STRUCTURE; SURFACE; GAP; GRAPHITE; LITHIUM; ENERGY; STATE; C6CA AB There is a great deal of fundamental and practical interest in the possibility of inducing superconductivity in a monolayer of graphene. But while bulk graphite can be made to superconduct when certain metal atoms are intercalated between its graphene sheets, the same has not been achieved in a single layer. Moreover, there is a considerable debate about the precise mechanism of superconductivity in intercalated graphite. Here we report angleresolved photoelectron spectroscopy measurements of the superconducting graphite intercalation compound CaC6 that distinctly resolve both its intercalant-derived interlayer band and its graphene-derived pi* band. Our results indicate the opening of a superconducting gap in the pi* band and reveal a substantial contribution to the total electron-phonon-coupling strength from the pi*-interlayer interband interaction. Combined with theoretical predictions, these results provide a complete account for the superconducting mechanism in graphite intercalation compounds and lend support to the idea of realizing superconducting graphene by creating an adatom superlattice.

TI A mixed-integer nonlinear program for the optimal design and dispatch of distributed generation systems SO OPTIMIZATION AND ENGINEERING LA English DT Article DE Global optimization; Mixed-integer nonlinear programming; Distributed generation; Combined heat and power ID OPTIMIZATION; NONCONVEX AB Maturing distributed generation (DG) technologies have promoted interest in alternative sources of energy for commercial building applications due to their potential to supply on-site heat and power at a lower cost and emissions rate compared to centralized generation. Accordingly, we present an optimization model that determines the mix, capacity, and operational schedule of DG technologies that minimize economic and environmental costs subject to the heat and power demands of a building and to the performance characteristics of the technologies. The technologies available to design the system include lead-acid batteries, photovoltaic cells, solid oxide fuel cells, heat exchangers, and a hot water storage tank. Modeling the acquisition and operation of discrete technologies requires integer restrictions, and modeling the variable electric efficiency of the fuel cells and the variable temperature of the tank water introduces nonlinear equality constraints. Thus, our optimization model is a nonconvex, mixed-integer nonlinear programming (MINLP) problem. Given the difficulties associated with solving large, nonconvex MINLPs to global optimality, we present convex underestimation and linearization techniques to bound and solve the problem. The solutions provided by our techniques are close to those provided by existing MINLP solvers for small problem instances. However, our methodology offers the possibility to solve large problem instances that exceed the capacity of existing solvers and that are critical to the real-world application of the model.

TI Opacity and gradients in aluminum wire array z-pinch implosions on the Z pulsed power facility SO PHYSICS OF PLASMAS LA English DT Article ID PLASMAS; DIAGNOSTICS; TRANSPORT; ARGON AB Aluminum wire array z pinches imploded on the Z generator are an extremely bright source of 1-2 keV radiation, with close to 400 kJ radiated at photon energies >1 keV and more than 50 kJ radiated in a single line (Al Ly-alpha). Opacity plays a critical role in the dynamics and K-shell radiation efficiency of these pinches. Where significant structure is present in the stagnated pinch this acts to reduce the effective opacity of the system as demonstrated by direct analysis of spectra. Analysis of time-integrated broadband spectra (0.8-25 keV) indicates electron temperatures ranging from a few 100eV to a few keV are present, indicative of substantial temperature gradients.

Khudik, Vladimir N. Schollmeier, Marius TI Enhancement of laser-driven electron acceleration in an ion channel SO PHYSICS OF PLASMAS LA English DT Article ID PULSES; GENERATION AB A laser beam with duration longer than the period of plasma oscillations propagating through an underdense plasma produces a steady-state positively charged channel in the electron density. We consider a test electron in the two-dimensional plane channel under the combined action of the laser field and the transverse static electric field of the channel. At ultrarelativistic laser wave amplitude (a >> 1), the electron is pushed primarily forward. As the electron gradually dephases from the wave, the field it samples and its relativistic gamma-factor strongly oscillate. The natural frequency of electron oscillations across the channel (betatron frequency) depends on gamma, which couples the betatron oscillations to the longitudinal motion induced by the wave. We show that the modulation of the natural frequency makes the oscillations unstable. The resulting amplification of the oscillations across the channel reduces the axial dephasing between the electron and the wave, leading to a considerable electron energy enhancement well above the ponderomotive energy. We find that there is a well-pronounced laser amplitude threshold a(*), above which the enhancement takes place, that scales as a(*) alpha 1/root n(0), where n(0) is the ion density. The presented mechanism of energy enhancement is robust with respect to a longitudinal variation of the density, because it relies on a threshold phenomenon rather than on a narrow linear resonance.

There is a need for an approximate and efficient method of solving the inner layer equations in all these regimes. In this paper, we introduce a method of solving the inner layer equations based on using a variational principle with Pade approximants. For all the regimes considered, the main layer equations to be solved are inhomogeneous, and Pade approximants give a convenient and efficient method of satisfying the correct asymptotic behavior at the edge of the layer. Results using this variational principle-Pade approximant method in three of these regimes is presented. These regimes are the constant-psi resistive-inertial (RI) regime, the constant-psi viscoresistive regime, and the non-constant-psi inviscid tearing regime. The last regime includes the constant-psi RI regime and the inertial regime. The results show that reasonable accuracy can be obtained very efficiently with Pade approximants having a small number of parameters. (C) 2014 AIP Publishing LLC.

TI On the nature of kinetic electrostatic electron nonlinear (KEEN) waves SO PHYSICS OF PLASMAS LA English DT Article ID ADIABATIC-INVARIANT; ACOUSTIC-WAVES; DENSITY HOLES; PLASMA-WAVES; INSTABILITY; MOTION AB An analytical theory is proposed for the kinetic electrostatic electron nonlinear (KEEN) waves originally found in simulations by Afeyan et al. [arXiv: 1210.8105]. We suggest that KEEN waves represent saturated states of the negative mass instability (NMI) reported recently by Dodin et al. [Phys. Rev. Lett. 110, 215006 (2013)]. Due to the NMI, trapped electrons form macroparticles that produce field oscillations at harmonics of the bounce frequency. At large enough amplitudes, these harmonics can phase-lock to the main wave and form stable nonlinear dissipationless structures that are nonstationary but otherwise similar to Bernstein-Greene-Kruskal modes. The theory explains why the formation of KEEN modes is sensitive to the excitation scenario and yields estimates that agree with the numerical results of Afeyan et al. A new type of KEEN wave may be possible at even larger amplitudes of the driving field than those used in simulations so far. (C) 2014 AIP Publishing LLC. C1 [Dodin, I. Y.; Fisch, N.

The parametric dependencies of the model are modified to achieve more accuracy compared to the results of the Vlasov solver both in regards to a mode amplitude's time evolution to a saturated state and its final steady state amplitude in the parameter space of the model's applicability. However, the regions of stability as predicted by LBQ model and BOT are found to significantly differ from each other. The solutions of the BOT simulations are found to have a larger region of instability than the LBQ simulations. (C) 2014 AIP Publishing LLC.

We use detailed atomic-kinetic and spectral simulations to analyze the absorption spectra of a photoionized neon plasma driven by the x-ray flux from a z-pinch. The broadband x-ray flux both photoionizes and backlights the plasma. In particular, we focus on extracting the charge state distribution of the plasma and the characteristics of the radiation field driving the plasma in order to estimate the ionisation parameter.

We present extended modeling of the x-ray emission spectrum reported by Colgan et al. [Phys. Rev.

We show that both accuracy and completeness in the modeled energy level structure are critical for reliable diagnostics, investigate how emission changes with different treatments of ionization potential depression, and discuss two approaches to handling the extensive structure required for hollow-ion models with many multiply excited configurations.

TI Debye scale turbulence within the electron diffusion layer during magnetic reconnection SO PHYSICS OF PLASMAS LA English DT Article ID 2-STREAM INSTABILITY; PLASMA SIMULATION; LABORATORY PLASMA; X-LINE; ACCELERATION; FIELD AB During collisionless, anti-parallel magnetic reconnection, the electron diffusion layer is the region of both fieldline breaking and plasma mixing. Due to the in-plane electrostatic fields associated with collisionless reconnection, the inflowing plasmas are accelerated towards the X-line and form counter-streaming beams within the unmagnetized diffusion layer. This configuration is inherently unstable to in-plane electrostatic streaming instabilities provided that there is sufficient scale separation between the Debye length lambda(D) and the electron skin depth c/omega(pe). This scale separation has hitherto not been well resolved in kinetic simulations. Using both 2D fully kinetic simulations and a simple linear model, we demonstrate that these in-plane streaming instabilities generate Debye scale turbulence within the electron diffusion layer at electron temperatures relevant to magnetic reconnection both in the magnetosphere and in laboratory experiments.

TI K-alpha and bremsstrahlung x-ray radiation backlighter sources from short pulse laser driven silver targets as a function of laser pre-pulse energy SO PHYSICS OF PLASMAS LA English DT Article ID RADIOGRAPHY; PRESSURE AB Measurements of silver K-shell and bremsstrahlung emission from thin-foil laser targets as a function of laser prepulse energy are presented. The silver targets were chosen as a potential 22 keV backlighter source for the National Ignition Facility Experiments. The targets were irradiated by the Titan laser with an intensity of 8 x 10(17) W/cm(2) with 40 ps pulse length. A secondary nanosecond timescale laser pulse with controlled, variable energy was used to emulate the laser prepulse. Results show a decrease in both K-alpha and bremsstrahlung yield with increasing artificial prepulse. Radiation hydrodynamic modeling of the prepulse interaction determined that the preplasma and intact target fraction were different in the three prepulse energies investigated. Interaction of the short pulse laser with the resulting preplasma and target was then modeled using a particle-in-cell code PSC which explained the experimental results. The relevance of this work to future Advanced Radiographic Capability laser x-ray backlighter sources is discussed. (C) 2014 AIP Publishing LLC. C1 [Jarrott, L.

Emphasis is placed on utilizing progressively more comprehensive models in order to identify the essential physics for computing the fast ion tail at energies comparable to the Gamow peak. The resulting fast ion tail distribution is subsequently used to compute the fusion reactivity as a function of collisionality and temperature. While a significant reduction of the fusion reactivity in the hot spot compared to the nominal Maxwellian case is present, this reduction is found to be partially recovered by an increase of the fusion reactivity in the neighboring cold region.

TI Collisional effects in the ion Weibel instability for two counter-propagating plasma streams SO PHYSICS OF PLASMAS LA English DT Article ID MAGNETIC-FIELDS; SHOCKS AB Experiments directed towards the study of the collisionless interaction between two counter-streaming plasma flows generated by high-power lasers are designed in such a way as to make collisions between the ions of the two flows negligibly rare. This is reached by making flow velocities v as high as possible and thereby exploiting the 1/v(4) dependence of the Rutherford cross-section. At the same time, the plasma temperature of each flow may be relatively low so that collisional mean-free paths for the intra-stream particle collisions may be much smaller than the characteristic spatial scale of the unstable modes required for the shock formation. The corresponding effects are studied in this paper for the case of the ion Weibel (filamentation) instability. Dispersion relations for the case of strong intra-stream collisions are derived. It is shown that the growth-rates become significantly smaller than those stemming from a collisionless model. The underlying physics is mostly related to the increase of the electron stabilizing term. Additional effects are an increased "stiffness" of the collisional ion gas and the ion viscous dissipation. A parameter domain where collisions are important is identified. (C) 2014 AIP Publishing LLC. C1 [Ryutov, D. D.; Fiuza, F.; Huntington, C. M.; Ross, J.

TI Radiation from mixed multi-planar wire arrays SO PHYSICS OF PLASMAS LA English DT Article ID PLASMAS; ZEBRA; UNR; SINGLE AB The study of radiation from different wire materials in wire array Z-pinch plasma is a very challenging topic because it is almost impossible to separate different plasmas at the stagnation. A new approach is suggested based on planar wire array (PWA) loads to assess this problem. Multi-planar wire arrays are implemented that consist of few planes, each with the same number of wires and masses but from different wire materials, arranged in parallel rows. In particular, the experimental results obtained with triple PWAs (TPWAs) on the UNR Zebra generator are analyzed with Wire Ablation Dynamics Model, non-local thermodynamic equilibrium kinetic model, and 2D radiation magneto-hydrodynamic to illustrate this new approach. In TPWAs, two wire planes were from mid-atomic-number wire material and another plane was from alloyed Al, placed either in the middle or at the edge of the TPWA. Spatial and temporal properties of K-shell Al and L-shell Cu radiations were analyzed and compared from these two configurations of TPWAs. Advantages of the new approach are demonstrated and future work is discussed. (C) 2014 AIP Publishing LLC. C1 [Safronova, A. S.; Kantsyrev, V. L.; Esaulov, A. A.; Weller, M. E.; Shlyaptseva, V.

TI Reduced Fokker-Planck models for fast particle distribution across a transition layer of disparate plasma temperatures SO PHYSICS OF PLASMAS LA English DT Article ID KINETIC SIMULATIONS; HEAT-TRANSPORT; IMPLOSIONS; GRADIENTS AB Across a transition layer of disparate plasma temperatures, the high energy tail of the plasma distribution can have appreciable deviations from the local Maxwellian distribution due to the Knudson layer effect. The Fokker-Planck equation for the tail particle population can be simplified in a series of practically useful limiting cases. The first is the approximation of background Maxwellian distribution for linearizing the collision operator. The second is the supra-thermal particle speed ordering of v(Ti) << v << v(Te) for the tail ions and v(Ti) << v(Te) << v for the tail electrons. Keeping both the collisional drag and energy scattering is essential for the collision operator to produce a Maxwellian tail distribution. The Fokker-Planck model for following the tail ion distribution for a given background plasma profile is explicitly worked out for systems of one spatial dimension, in both slab and spherical geometry. A third simplification is an expansion of the tail particle distribution using the spherical harmonics, which are eigenfunctions of the pitch angle scattering operator. This produces a set of coupled Fokker-Planck equations that contain energy-dependent spatial diffusion terms in two coordinates (position and energy), which originate from pitch angle scattering in the original Fokker-Planck equation. It is shown that the well-known diffusive Fokker-Planck model is a poor approximation of the two-mode truncation model, which itself has fundamental deficiency compared with the three-mode truncation model. The cause is the lack of even-symmetry representation in pitch dependence in the two-mode truncation model. (C) 2014 AIP Publishing LLC. C1 [Tang, Xian-Zhu; Guo, Zehua; McDevitt, C.

TI A hybrid model for coupling kinetic corrections of fusion reactivity to hydrodynamic implosion simulations SO PHYSICS OF PLASMAS LA English DT Article ID STEEP TEMPERATURE-GRADIENTS; HEAT-TRANSPORT; PLASMA AB Inertial confinement fusion requires an imploded target in which a central hot spot is surrounded by a cold and dense pusher. The hot spot/pusher interface can take complicated shape in three dimensions due to hydrodynamic mix. It is also a transition region where the Knudsen and inverse Knudsen layer effect can significantly modify the fusion reactivity in comparison with the commonly used value evaluated with background Maxwellians. Here, we describe a hybrid model that couples the kinetic correction of fusion reactivity to global hydrodynamic implosion simulations. The key ingredient is a non-perturbative treatment of the tail ions in the interface region where the Gamow ion Knudsen number approaches or surpasses order unity. The accuracy of the coupling scheme is controlled by the precise criteria for matching the non-perturbative kinetic model to perturbative solutions in both configuration space and velocity space.

TI Particle-in-cell simulations of laser beat-wave magnetization of dense plasmas SO PHYSICS OF PLASMAS LA English DT Article ID FIELD-REVERSED CONFIGURATIONS; INERTIAL CONFINEMENT FUSION; CURRENT DRIVE; TRANSPORT; GENERATION; EXCITATION; TARGET; FUEL AB The interaction of two lasers with a difference frequency near that of the ambient plasma frequency produces beat waves that can resonantly accelerate thermal electrons. These beat waves can be used to drive electron current and thereby embed magnetic fields into the plasma [Welch et al., Phys. Rev. Lett. 109, 225002 (2012)]. In this paper, we present two-dimensional particle-in-cell simulations of the beat-wave current-drive process over a wide range of angles between the injected lasers, laser intensities, and plasma densities. We discuss the application of this technique to the magnetization of dense plasmas, motivated in particular by the problem of forming high-beta plasma targets in a standoff manner for magneto-inertial fusion. The feasibility of a near-term experiment embedding magnetic fields using lasers with micron-scale wavelengths into a similar to 10(18) cm(-3)-density plasma is assessed. (C) 2014 AIP Publishing LLC.

TI Characterization of the fast electrons distribution produced in a high intensity laser target interaction SO PHYSICS OF PLASMAS LA English DT Article ID SOLID TARGETS; PHOTON AB Experiments on the Titan laser (similar to 150 J, 0.7 ps, 2 x 10(20) W cm(-2)) at the Lawrence Livermore National Laboratory were carried out in order to study the properties of fast electrons produced by high-intensity, short pulse laser interacting with matter under conditions relevant to Fast Ignition. Bremsstrahlung x-rays produced by these fast electrons were measured by a set of compact filter-stack based x-ray detectors placed at three angles with respect to the target. The measured bremsstrahlung signal allows a characterization of the fast electron beam spectrum, conversion efficiency of laser energy into fast electron kinetic energy and angular distribution. A Monte Carlo code Integrated Tiger Series was used to model the bremsstrahlung signal and infer a laser to fast electron conversion efficiency of 30%, an electron slope temperature of about 2.2 MeV, and a mean divergence angle of 39 degrees. Simulations were also performed with the hybrid transport code ZUMA which includes fields in the target. In this case, a conversion efficiency of laser energy to fast electron energy of 34% and a slope temperature between 1.5 MeV and 4 MeV depending on the angle between the target normal direction and the measuring spectrometer are found. The observed temperature of the bremsstrahlung spectrum, and therefore the inferred electron spectrum are found to be angle dependent. (C) 2014 AIP Publishing LLC. C1 [Westover, B.; Beg, F.

The canonical description of the gyrocenter has both theoretical and practical importance. We provide a general procedure of the gyrocenter canonicalization, which is expressed by the series of a small variable epsilon depending only on the parallel velocity u and can be expressed in a recursive manner. We prove that the truncation of the series to any given order generates a set of exact canonical coordinates for a system, whose Lagrangian approximates to that of the original gyrocenter system in the same order. If flux surfaces exist for the magnetic field, the series stops simply at the second order and an exact canonical form of the gyrocenter system is obtained. With the canonicalization schemes, the canonical symplectic simulation of gyrocenter dynamics is realized for the first time. The canonical symplectic algorithm has the advantage of good conservation properties and long-term numerical accuracy, while avoiding numerical instability. It is worth mentioning that explicitly expressing the canonical Hamiltonian in new coordinates is usually difficult and impractical. We give an iteration procedure that is easy to implement in the original coordinates associated with the coordinate transformation. This is crucial for modern large-scale simulation studies in plasma physics. The dynamics of gyrocenters in the dipole magnetic field and in the toroidal geometry are simulated using the canonical symplectic algorithm by comparison with the higher-order non symplectic Runge-Kutta scheme. The overwhelming superiorities of the symplectic method for the gyrocenter system are evidently exhibited. (C) 2014 AIP Publishing LLC.

TI The Sloan Digital Sky Survey quasar catalog: tenth data release SO ASTRONOMY & ASTROPHYSICS LA English DT Article DE catalogs; surveys; quasars: general ID OSCILLATION SPECTROSCOPIC SURVEY; BROAD ABSORPTION-LINE; EFFICIENT PHOTOMETRIC SELECTION; BARYON ACOUSTIC-OSCILLATIONS; QSO REDSHIFT SURVEY; 9TH DATA RELEASE; SDSS-III; TARGET SELECTION; LUMINOSITY FUNCTION; SYSTEM AB We present the Data Release 10 Quasar (DR10Q) catalog from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III. The catalog includes all BOSS objects that were targeted as quasar candidates during the first 2.5 years of the survey and that are confirmed as quasars via visual inspection of the spectra, have luminosities M-i[z = 2] < -20.5 (in a ACDM cosmology with H-0 = 70 km s(-1) Mpc(-1), Omega(M) = 0.3, and Omega(A) = 0.7), and either display at least one emission line with a full width at half maximum (FWHM) larger than 500 km s(-1) or, if not, have interesting/complex absorption features. The catalog also includes known quasars (mostly from SDSS-I and II) that were reobserved by BOSS. The catalog contains 166 583 quasars (74 454 are new discoveries since SDSS-DR9) detected over 6373 deg(2) with robust identification and redshift measured by a combination of principal component eigenspectra. The number of quasars with z > 2.15 (117 668) is similar to 5 times greater than the number of z > 2.15 quasars known prior to BOSS. Redshifts and FWHMs are provided for the strongest emission lines (C IV, C III, Mg II). The catalog identifies 16 461 broad absorption line quasars and gives their characteristics. For each object, the catalog presents five-band (u, g, r, i, z) CCD-based photometry with typical accuracy of 0.03 mag and information on the optical morphology and selection method. The catalog also contains X-ray, ultraviolet, near-infrared, and radio emission properties of the quasars, when available, from other large-area surveys. The calibrated digital spectra cover the wavelength region 3600-10 500 angstrom at a spectral resolution in the range 1300 < R < 2500; the spectra can be retrieved from the SDSS Catalog Archive Server. We also provide a supplemental list of an additional 2376 quasars that have been identified among the galaxy targets of the SDSS-III/BOSS.

The physical properties of the pelletised biomass studied are: (a) pellet moisture content, (b) unit, bulk and tapped density, and (c) durability. Pelletisation experiments were conducted based on central composite design. Analysis of variance (ANOVA) indicated that feedstock moisture content influenced all of the physical properties at P < 0.001. Pellet moisture content decreased with increase in preheating temperature to about 110 degrees C and decreasing the feedstock moisture content to about 28% (w.b.). Response surface models developed for quality attributes with respect to process variables has adequately described the process with coefficient of determination (R-2) values of >0.88. The other pellet quality attributes such as unit, bulk, tapped density, were maximised at feedstock moisture content of 30-33% (w.b.), die speeds of >50 Hz and preheating temperature of >90 degrees C. In case of durability a medium moisture content of 33-34% (w.b.) and preheating temperatures of >70 degrees C and higher die speeds >50 Hz resulted in high durable pellets. It can be concluded from the present study that feedstock moisture content, followed by preheating, and die rotational speed are the interacting process variables influencing pellet moisture content, unit, bulk and tapped density and durability.

In the present work, lithium conducting electrolytes based on 1-cyanomethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([CCNIm(+)][TFSI-]) and 1-cyanopropyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C(3)CNIm(+)][TFSI-]) with lithium bis(trifluoromethysulfonyl)imide (LiTFSI) were investigated. An IL gel electrolyte membrane was obtained by immersing a composite PVdF-HFP membrane in the IL electrolyte. PVdF/HFP copolymer-based gel polymer electrolytes containing Al2O3 and TiO2 fillers (raw and surface-modified with acid groups) were synthesized and studied. The highest values of ionic conductivity and lithium ion transference numbers were observed for membranes based on pristine copolymer and doped with TiO2 in 0.1 or 0.5 M LiTFSI in [C(3)CNIm(+)][TFSI-]. The ionic conductivity was equal to 3 x 10(-4) S cm(-1), and t(+) = 0.3. The addition of Al2O3 led to a threefold decrease in the electrolyte/electrode interface resistance, which stabilized at 1500 Omega. Thermal analysis confirmed the stability of the membranes up to 200 degrees C and a twofold decrease in the polymer's degree of crystallinity after the addition of inorganic fillers.

TI Characterizing the elements of Earth's radiative budget: Applying uncertainty quantification to the CESM SO JOURNAL OF COMPUTATIONAL SCIENCE LA English DT Article DE Climate modeling; Uncertainty quantification; Error estimation ID DIFFERENTIAL-EQUATIONS; POLYNOMIAL CHAOS; CLIMATE AB Understanding and characterizing sources of uncertainty in climate modeling is an important task. Because of the ever increasing sophistication and resolution of climate modeling it is increasingly important to develop uncertainty quantification methods that minimize the computational cost that occurs when these methods are added to climate modeling. This research explores the application of sparse stochastic collocation with polynomial edge detection to characterize portions of the probability space associated with the Earth's radiative budget in the Community Earth System Model (CESM). Specifically, we develop surrogate models with error estimates for a range of acceptable input parameters that predict statistical values of the Earth's radiative budget as derived from the CESM simulation. We extend these results in resolution from T31 to T42 and in parameter space increasing the degrees of freedom from two to three. Published by Elsevier B.V.

TI Gaining insights into reactive fluid-fractured rock systems using the temporal moments of a tracer breakthrough curve SO JOURNAL OF CONTAMINANT HYDROLOGY LA English DT Article DE Reactive transport; Tracer breakthrough curve; Temporal moments; Fractured rocks ID MATRIX DIFFUSION; CONTAMINANT TRANSPORT; WEATHERING RATES; FISSURED ROCKS; AQUIFER; CHRONOSEQUENCE; COEFFICIENTS; GROUNDWATER; DISSOLUTION; DISPERSION AB In this paper, we show that the tracer breakthrough curves (BTCs), when the tracer chemically interacts with the solid matrix of a fractured rock, are considerably different than when it does not. Of particular interest, is the presence of a long pseudo steady state zone in the BTCs, where the tracer concentration is more or less constant over a long period of time. However, such a zone of constant concentration is not visible when either the tracer does not interact with the solid, or does so at an extremely fast rate. We show that these characteristics of the BTCs could be correlated to the parameters of the system. We develop expressions for the mean residence time and its variance for a chemically active and inactive tracer. We show that chemical interaction between the tracer and the solid increases the mean residence time and the increase depends on the distribution coefficient. We also show that the variance of residence time for a chemically active tracer is much larger than that for an inactive tracer, and it depends on both the distribution coefficient and the rate of chemical reaction. We verify these calculations against synthetic tracer BTCs, where the temporal moments are calculated by numerically integrating the tracer evolution curves. Even though we developed the mathematical expressions assuming an idealized fracture-matrix system, we believe that the mathematical expressions developed in this paper can be useful in gaining insights into reactive transport in a real fractured rock system.

TI Force measurements of a magnetic micro actuator proposed for a microvalve array SO JOURNAL OF MICROMECHANICS AND MICROENGINEERING LA English DT Article; Proceedings Paper CT 7th International Conference on Microtechnologies in Medicine and Biology (MMB) CY APR 10-12, 2013 CL Marina Del Rey, CA DE magnetic actuation; microvalve; bead transport; magnetic force measurements ID ON-CHIP; MANIPULATION; VALVES AB Low-cost, easily-fabricated and power-efficient microvalves are necessary for many microfluidic lab-on-a-chip applications. In this study, we present a simple, low-power, scalable, CMOS-compatible magnetic actuator for microvalve applications composed of a paramagnetic bead as the ball valve over a picoliter reaction well etched into a silicon substrate. The paramagnetic bead, composed of either pure FeSi or magnetite in a SiO2 matrix, is actuated by the local magnetic field gradient generated by a microcoil in an aqueous environment, and the reaction well is situated at the microcoil center. A permanent magnet beneath the microvalve device provides an external magnetic biasing field that magnetizes the bead, enabling bidirectional actuation and reducing the current required to actuate the bead to a level below 10 mA. The vertical and radial magnetic forces exerted on the bead by the microcoil were measured for both pure FeSi and composite beads and agree well with the predictions of 2D axisymmetric finite element method models. Vertical forces were within a range of 13-80 nN, and radial forces were 11-60 nN depending on the bead type. The threshold current required to initiate bead actuation was measured as a function of bead diameter and is found to scale inversely with volume for small beads, as expected based on the magnetic force model. To provide an estimate of the stiction force acting between the bead and the passivation layer on the substrate, repeated actuation trials were used to study the bead throw distance for substrates coated with silicon dioxide, Parylene-C, and photoresist. The stiction observed was lowest for a photoresist-coated substrate, while silicon dioxide and Parylene-C coated substrates exhibited similar levels of stiction.

Solar energy feasibility entails the development of energy storage systems since solar power plants need to be working in unfavorable weather or night periods. The main heat transfer fluid (HTF) used on these plants is a salt mixture of 60% NaNO3/40% NaNO3 which must be kept above 220 degrees C to prevent freezing. This high operating temperature causes corrosion problems for steels in contact with the HTF, reducing the lifetime of the solar plants. The present research studies the potential of an alumina-forming austenitic (AFA) stainless steel (OC-4, Fe-25Ni-14Cr-3.5Al-2.5Nb wt% base) as a candidate material for solar plant heat exchangers and pipes. Corrosion behavior of OC-4, relative to 304 stainless steel and T22 steel, was studied by gravimetric analysis and electrochemical impedance spectroscopy (EIS). The AFA OC-4 exhibited better corrosion resistance in HTF at 390 degrees C than the currently used 304 austenitic stainless steel. C1 [Fernandez, A. G.; Rey, A.; Lasanta, I.; Mato, S.; Perez, F.

Using correlated ensemble-averaged high-throughput X-ray absorption spectroscopy and spatially resolved electron microscopy and spectroscopy, here we report structural reconstruction (formation of a surface reduced layer, R (3) over barm to Fm (3) over barm transition) and chemical evolution (formation of a surface reaction layer) at the surface of LiNixMnxCo1-2xO2 particles. These are primarily responsible for the prevailing capacity fading and impedance buildup under high-voltage cycling conditions, as well as the first-cycle coulombic inefficiency. It was found that the surface reconstruction exhibits a strong anisotropic characteristic, which predominantly occurs along lithium diffusion channels. Furthermore, the surface reaction layer is composed of lithium fluoride embedded in a complex organic matrix. This work sets a refined example for the study of surface reconstruction and chemical evolution in battery materials using combined diagnostic tools at complementary length scales.

TI Activation pathway of Src kinase reveals intermediate states as targets for drug design SO NATURE COMMUNICATIONS LA English DT Article ID C-SRC; STRING METHOD; CONFORMATIONAL-CHANGES; ATOMISTIC SIMULATIONS; ACTIVE CONFORMATION; MOLECULAR-DYNAMICS; CRYSTAL-STRUCTURE; PROTEIN-KINASES; HIV-1 PROTEASE; ABL KINASE AB Unregulated activation of Src kinases leads to aberrant signalling, uncontrolled growth and differentiation of cancerous cells. Reaching a complete mechanistic understanding of largescale conformational transformations underlying the activation of kinases could greatly help in the development of therapeutic drugs for the treatment of these pathologies. In principle, the nature of conformational transition could be modelled in silico via atomistic molecular dynamics simulations, although this is very challenging because of the long activation timescales. Here we employ a computational paradigm that couples transition pathway techniques and Markov state model-based massively distributed simulations for mapping the conformational landscape of c-src tyrosine kinase. The computations provide the thermodynamics and kinetics of kinase activation for the first time, and help identify key structural intermediates.

The electrochemical and photophysical properties of these "pyrylogen" sensitizers are reported in sufficient detail to allow rationale design of new photoinduced electron transfer reactions. The range of their reduction potentials (+0.37-+0.05V vs SCE) coupled with their range of singlet (48-63 kcal mol(-1)) and triplet (48-57kcalmol(-1)) energies demonstrate that they are potent oxidizing agents in both their singlet and triplet excited states, thermodynamically capable of oxidizing substrates with oxidation potentials as high as 3.1eV. The pyrylogens are synthesized in three steps from readily available starting materials in modest overall 11.4-22.3% yields. These sensitizers have the added advantages that: (1) their radical cations do not react on the CV timescale with oxygen bypassing the need to run reactions under nitrogen or argon and (2) have long wavelength absorptions between 413 and 523nm well out of the range where competitive absorbance by most substrates would cause a problem. These new sensitizers do react with water requiring special precautions to operate in a dry reaction environment. C1 [Clennan, Edward L.] Univ Wyoming, Dept Chem, Laramie, WY 82071 USA.

It is generally acknowledged that there exist quantitative differences between 2D and three-dimensional (3D) numerical simulations. However, no detailed study evaluating such differences can be found for simulations of CFB risers. This paper presents 2D and 3D numerical simulations of three different CFB risers. Axial pressure gradients from both 2D and 3D simulations are compared with the experimental data. It has been clearly demonstrated that the 2D simulation cannot satisfactorily reproduce the 3D simulation results. A further comparison of radial profiles of void fraction and solids velocity for an axi-symmetric riser configuration is reported and the quantitative differences between 2D and 3D simulations are analyzed. In conclusion, 2D simulation is only recommended for qualitative evaluation and 3D modeling is recommended for predictive simulations. (C) 2014 Elsevier B.V. All rights reserved.

It is demonstrated that the grid convergence of numerical simulations depends on the flow field variable chosen for verification. For axial pressure gradient, this study shows that no general rule for grid size is available to guarantee the grid-independent results. In addition, the inlet and outlet configuration used in the 2D simulations shows a significant impact on the grid convergence. A 3D grid study is also presented with the intent to probe the differences between 2D and 3D numerical simulations with respect to the grid convergence. For the case considered in this study, the 3D simulation demonstrates better grid convergent behavior than the 2D simulation with comparable grid sizes. (C) 2014 Elsevier B.V. All rights reserved.

Tubules are quite small, diameter approximate to 2 mu m, and this makes the near-tubule region of dentin difficult to study. Here, advanced characterization techniques are applied in a novel way to examine what organic or nanostructural signatures may indicate the end of ITD or the beginning of PTD mineralization. X-ray fluorescence intensity (Ca, P, and Zn) and X-ray diffraction patterns from carbonated apatite (cAp) were mapped around dentintubules at resolutions ten times smaller than the feature size (200nm pixels), representing a 36% increase in resolution over earlier work. In the near tubule volumes of near-pulp, root dentin, Zn intensity was higher than in ITD remote from the tubules. This increase in Zn2+, as determined by X-ray absorption near edge structure analysis, may indicate the presence of metalloenzymes or transcription factors important to ITD or PTD mineralization. The profiles of the cAp 00.2 X-ray diffraction rings were fitted with a pseudo-Voigt function, and the spatial and azimuthal distribution of these rings' integrated intensities indicated that the cAp platelets were arranged with their c-axes aligned tangential to the edge of the tubule lumen. This texture was continuous throughout the dentin indicating a lack of structural difference between in the Zn rich near-tubular region and the remote ITD. SCANNING 36:231-240, 2014.

Therefore, studies investigating the role of this climate driver on forest floor fauna arc timely. We examined the impact of precipitation alteration over 13 years on Coleoptera (specifically Family Carabidae) communities in a temperate forest by testing the effects of dry (33% precipitation interception), ambient (control), and wet (33% precipitation addition) treatments. We collected insects in pitfall traps and quantified forest-floor physical and chemical parameters. Beetle abundance and Carabidac tribe richness were significantly reduced in dry plots. Community similarity was substantially higher between wet and ambient plots compared to dry plots due to the substantial reduction of three dominant carabid tribes. Litter mass increased overall, litter nitrogen decreased, and carbon:nitrogen ratio (C:N) and total phenolics increased in the dry-plot Oi horizon. Beetle abundance and tribe richness were positively related to soil moisture, and beetle abundance was negatively related to litter mass. Microarthropod abundance was highest in the dry treatment. This study provides evidence that shifting precipitation patterns predicted with climate change could alter important ground-fauna communities in extensive ecosystems such as temperate forests.

However, since as-grown SWCNTs possess a distribution of physical and electronic structures, it is of high interest to determine which subpopulations of SWCNTs possess the highest lithiation capacity and to develop processing methods that can enhance the lithiation capacity of underperforming SWCNT species. Toward this end, SWCNT electronic type purity is controlled via density gradient ultracentrifugation, enabling a systematic study of the lithiation of SWCNTs as a function of metal versus semiconducting content. Experimentally, vacuum-filtered freestanding films of metallic SWCNTs are found to accommodate lithium with an order of magnitude higher capacity than their semiconducting counterparts, which is consistent with ab initio molecular dynamics and density functional theory calculations in the limit of isolated SWCNTs. In contrast, SWCNT film densification leads to the enhancement of the lithiation capacity of semiconducting SWCNTs to levels comparable to metallic SWCNTs, which is corroborated by theoretical calculations that show increased lithiation of semiconducting SWCNTs in the limit of small SWCNT SWCNT spacing. Overall, these results will inform ongoing efforts to utilize SWCNTs as conductive additives in nanocomposite lithium ion battery electrodes.

However, methods for synthesizing SWCNTs produce a mixture of metallic and semiconducting materials, which require additional processing to separate by electronic type. Purification and enrichment of the semiconducting fraction is readily achieved by using the centrifugation of aqueous suspensions of SWCNTs with the help of surfactants, but this leaves residual surfactant on the SWCNT surface that can impact their electronic and optical properties. Here, we present a detailed study of the sodium taurodeoxycholate (STDC) surfactant removal process during vacuum annealing, showing that it occurs through fragmentation of the surfactant, and that complete removal requires exceedingly high temperatures, which indicates strong binding to the SWCNTs. We then present an approach based on air oxidation and mild annealing to completely remove the surfactant while maintaining the SWCNT properties. Using this approach, we compare single SWCNT electronic devices with and without STDC and show that, despite the very strong surfactant binding, it does not affect device performance substantially.

However, the related structure property relationships remain largely unclear and the reported results are inconsistent. The details of the interactions of the charged carbon pore walls with electrolyte ions and solvent molecules at a subnanometer scale are still largely unknown. Here for the first time we utilize in situ small angle neutron scattering (SANS) to reveal the electroadsorption of organic electrolyte ions in carbon pores of different sizes. A 1 M solution of tetraethylammonium tetrafluoroborate (TEATFB) salt in deuterated acetonitrile (d-AN) was used in an activated carbon with the pore size distribution similar to that of the carbons used in commercial double layer capacitors. In spite of the incomplete wetting of the smallest carbon pores by the d-AN, we observed enhanced ion sorption in subnanometer pores under the applied potential. Such results suggest the visible impact of electrowetting phenomena counterbalancing the high energy of the carbon/electrolyte interface in small pores. This behavior may explain the characteristic butterfly wing shape of the cyclic voltammetry curve that demonstrates higher specific capacitance at higher applied potentials, when the smallest pores become more accessible to electrolyte. Our study outlines a general methodology for studying various organic salts solvent carbon combinations.

Following experimental result from cyclic voltammehy and ambient-pressure X-ray photoelectron spectroscopy, we postulate a near-resonant alignment of the PbS 1S(h) state and the organic HOMO, which is confirmed by atomistic calculations. Considering the large width of interparticle spacing, we observe an abnormally high field-effect hole mobility, which we attribute to the postulated resonance. In contrast to nanoparticle devices coupled through common short-chained ligands, our system maintains a large degree of macroscopic order as revealed by X-ray scattering.

We measure the differences in peak rupture force for azobenzene-modified DNA, as the incorporated azobenzenes are photoswitched reversibly between the trans and the cis form. Fitting our rupture force versus loading rate data, we obtain off rate (k(off)) at zero force values in the range of similar to 10 s(-1). We show that the change in peak rupture force and k(off) induced by destabilizing the DNA duplex depends on the position of the destabilizing azobenzene photoswitch relative to the force-loading site. When the azobenzenes are proximal to the unzipping end, the decrease in peak force and k(off) upon azobenzene photoisomerization is significantly larger than when the azobenzene is distal to the site of force loading. We interpret these results as experimental evidence supporting the picture that the destabilization of a double-stranded DNA by a photoswitch isomerization is localized to a small bubble around the photoswitch.

In view of the current interest in using eta-nucleus scattering length to infer the existence of eta-mesic nucleus, we derive general analytic expressions that relate the binding energy and half-width of an unstable bound state to the complex-valued scattering length due to the same particle-target interaction.

Specifically we consider the problem of reproducing the radiative forcing pathway for Representative Concentration Pathway, RCP4.5, which stabilizes radiative forcing at 4.5 W m(-2) (650 ppm CO2-e) under a different terrestrial policy assumption. We show that if indirect land-use change emissions are not priced, carbon prices that can replicate this pathway in the near-term may not exist. We further show that additional complexities could emerge as a consequence of the co-production of CO2 and sulfur emissions as byproducts of fossil fuel combustion. (C) 2013 Elsevier B.V.

Achieving the combination of high ionic conductivity and outstanding chemical stability in solid electrolytes is a grand challenge for the synthesis of solid electrolytes. Herein we report the design of aliovalent substitution of Li4SnS4 to achieve high conduction and excellent air stability based on the hard and soft acids and bases theory. The solid electrolyte of composition Li3.833Sn0.833As0.166S4 has a high ionic conductivity of 1.39 mS cm(-1) at 25 degrees C. Considering the high Li+ transference number, this phase conducts Li+ as well as carbonate-based liquid electrolytes. This research also addresses the compatibility of the sulfide-based solid electrolytes through chemical passivation.
