Injecting the working fluid from a large number of spatially distributed microholes rather than a few conventionally drilled wells is likely to provide access to a larger reservoir volume with enhanced overall flow distances between the injection and production wells and increased contact area between permeable fractures and the hot rock matrix. More importantly, it reduces the risk of preferential flow and early thermal breakthrough, making microhole array-based EGS a more robust design. Heat recovery factors are calculated for EGS reservoirs with a conventional well configuration and with microhole arrays. The synthetic reservoir has properties similar to those of the EGS test site at Soultz-sous-Forets. The wells and microholes are explicitly included in the numerical model. They intersect a stimulated reservoir region, which is modeled using a dual-permeability approach, as well as a wide-aperture zone, which is incorporated as a discrete feature. Local and global sensitivity analyses are used to examine the robustness of the design for a variety of reservoir and operating conditions. The simulations indicate that the flexibility offered by microhole drilling technology could provide an alternative EGS exploitation option with improved performance. (c) 2013 Elsevier Ltd.

There is currently an urgent need to develop a noninvasive diagnostic test for NOA. Altered microRNA (miRNA) profiles have been proposed as potential biomarkers for the diagnosis of disease states. A total of 200 subjects (n 100 for NOA, n 100 for fertile control) were recruited to participate in this study. Recruitment took place from May 2008 to June 2010. We employed a strategy consisting of initial screening by TaqMan Low Density Array then further validation with a TaqMan quantitative RTPCR assay. Validation of the profiling results was conducted in two independent phases. In addition, the expression of the three validated seminal plasma miRNAs (sp-miRNAs) was examined in testicular tissues of patients with NOA and of fertile controls. Methylation status and functional analyses were also performed for the identified sp-miRNAs. miR-141, miR-429 and miR-7-1-3p were significantly increased in seminal plasma of patients with NOA compared with fertile controls. As sensitive and specific biomarkers, the profiling of these three identified sp-miRNAs provides a novel noninvasive, semen-based test for NOA diagnosis. The methylation status of these sp-miRNAs was inversely associated with their expression patterns. Additionally, we found that Cbl and Tgf2 were down-regulated by miR-141, while Rb1 and Pik3r3 were down-regulated by miR-7-1-3p. miRNA expression profile was investigated in seminal plasma samples from only a small number of NOA patients. In future investigations, a larger sample size should be adopted and the functional role of the three sp-miRNAs should be further characterized in animal models. Given that sp-miRNAs show reproducible and stable expression levels, they are potentially novel noninvasive biomarkers for the diagnosis of NOA. We propose that the three sp-miRNAs described above may participate in a methylation-miRNA-gene network related to NOA development. This work provides a foundation for interpretation of miRNA changes associated with pathogenesis of NOA and extends the current understanding of human NOA pathogenesis.

For the back contact, its potential barrier decreases with Cu concentration, while its saturation current density increases. For the bulk CdTe, the hole density increases with Cu concentration. We identify a Cu-related deep level at similar to 0.55 eV whose concentration is significant when the Cu concentration is high. The device performance, which initially improves with Cu concentration then decreases, reflects the interplay between the positive influences (reducing the back-contact potential barrier while increasing the saturation current density of the back contact and hole density in CdTe bulk) and negative influences (increasing deep levels in CdTe) of Cu.

Self-healing is achieved via embedded microcapsules containing dicyclopentadiene monomer and solid particles of bis(tricyclohexylphosphine)-benzylidine ruthenium (IV) dichloride (Grubbs') catalyst. Recovery of fracture toughness is assessed through fracture testing of width tapered double cantilever beam (WTDCB) specimens. Healing efficiencies as high as 58% were achieved for 6.6 wt% DCPD microcapsules and 10 mg Grubbs' catalyst. However, virgin fracture toughness is reduced with the addition of ca. 117 mu m diameter microcapsules as a result of suppression of the damage zone as revealed by transmission optical micrographs. The uniform dispersal of microcapsules throughout a rubber toughened epoxy adhesive formulated using EPON 828, piperidine and CTBN alleviated the suppression effect and demonstrated retention of virgin fracture toughness of adhesives.

We conducted a step-rate water injection (similar to 3.5 MPa and 1200 s) to induce the local pressurization of a critically stressed fractured carbonate reservoir layer located at 250 m-depth in the Low Noise Underground Laboratory (LSBB), southern France. An observed factor-of-3 increase in the fracture permeability was associated with the injection-induced fluid pressure increase and about 100 triggered seismic events. Both normal opening (a few microns) of the fluid-injected fracture and the associated tilt ( <1 micro-radian) of the fracture near field displayed inelastic behavior highlighting an irreversible fracture shear and dilatant failure, amounting to about 1/3-1/2 of the maximum measured deformations. Using a plane-strain finite-difference coupled hydromechanical model, our calculation shows that tensile failure first occurred in the injection zone and then shear failure spread along fractures into the surrounding unsaturated rock through stress transfer from the injection zone. The most striking result of these model simulations is that the mechanical weakening of the fractures in the near field induced a 2-5 x 10(5) Pa release of the normal stress across the fluid-injected fracture that provoked fracture slip and increase in permeability. A geological exploration of the fracture zone after the experiment showed that no major failure had occurred, and we therefore relate these strength and permeability variations to the slight reactivation (similar to microns) of pre-existing fractures.

These, in turn, allow us to explore the geomagnetic response to continued and extreme driving of the magnetosphere. In this paper we shall discuss elements of the following: (i) anomalous features of the flow in the terrestrial magnetosheath during ICME/MC passage and (ii) large geomagnetic disturbances when total or partial mergers of ICMEs/MCs pass Earth. In (i) we emphasize two roles played by the upstream Alfven Mach number in solar wind-magnetosphere interactions: (i) It gives rise to wide plasma depletion layers. (ii) It enhances the magnetosheath flow speed on draped magnetic field lines. (By plasma depletion layer we mean a magnetosheath region adjacent to the magnetopause where magnetic forces dominate over hydrodynamic forces.) In (ii) we stress that the ICME mergers elicit geoeffects over and above those of the individual members. In addition, features of the non-linear behavior of the magnetosphere manifest themselves.

On global scales, simulation and statistical studies lead to mean configurations of dayside reconnection, implying specific relative alignments of the inflow magnetic fields and X-line, with implications for MMS operations designed to maximize the number of close encounters with the diffusion region. At intermediate MHD-to-ion scales, reconstruction of features created by one or two X-lines have developed to the point where data from a cluster of spacecraft can determine their temporal trends and the approximate three-dimensional X-line structure. Recent petascale particle-in-cell (PIC) simulations of reconnection encompass three spatial dimensions with excellent resolution, and make striking predictions of electron scale physics that creates complex interacting flux ropes under component reconnection. High time resolution measurements from MMS will determine the detailed electron scale kinetics embedded within the global and MHD-ion scale contexts. These developments will lead to the refinement of our three-dimensional multiscale picture of reconnection, yielding improved understanding of the global, MHD, and local physics controlling the onset or quenching, variability, and mean rate of reconnection.

TI The impact of geocoronal density on ring current development SO JOURNAL OF ATMOSPHERIC AND SOLAR-TERRESTRIAL PHYSICS LA English DT Article DE Inner magnetosphere; Ring current; Geocorona; Modeling ID ENERGETIC NEUTRAL ATOMS; CHARGE-EXCHANGE; PLASMA SHEET; CURRENT IONS; INNER MAGNETOSPHERE; MAGNETIC STORM; ELECTRIC-FIELD; HYDROGEN; DECAY; RADIATION AB Long-term ring current decay following a magnetic storm is mainly due to charge exchange collisions of ring current ions with geocoronal neutral atoms forming energetic neutral atoms (ENAs) that leave the ring current system. Therefore, the density distribution of these cold and tenuous neutral hydrogen atoms plays a key role in the ring current recovery. TWINS ENA images provide a direct measurement of these ENA losses and therefore insight into the dynamics of the ring current decay through interactions with the geocorona. To assess the influence of geocoronal neutrals on ring current decay, we compare the predicted ENA emission using five different geocoronal models and the HEIDI ring current model to simulate the July 22, 2009 storm. We show that for high energy H+ (>= 100 keV), all geocoronal models predict similar decay rates of the ring current ions. However, for low energy ions (<= 100 key), the decay rate varies significantly depending on the geocoronal density model. Comparison with TWINS ENA images shows that the location of the peak ENA enhancements is highly dependent on the distribution of geocoronal hydrogen density. The ring current topology depends greatly on the hydrogen model used, therefore knowing the H-distribution is very important in understanding how the ring current recovers following a magnetic storm.

This value is provided by the user, however, and has been repeatedly shown to be inaccurate. We studied the workload characteristic based on a large amount of historical data (over 275,000 jobs in two and a half years) from a production leadership-class computer. Based on that study, we proposed a set of walltime adjustment schemes producing more accurate estimates. To ensure the utility of these schemes on production systems, we analyzed their potential impact in scheduling and evaluated the schemes with an event-driven simulator. Our experimental results show that our method can achieve not only better overall estimation accuracy but also improved overall system performance. Specifically, the average estimation accuracy of the tested workload can be improved by up to 35%, and the system performance in terms of average waiting time and weighted average waiting time can be improved by up to 22% and 28%, respectively.

TI Kernel-assisted and topology-aware MPI collective communications on multicore/many-core platforms SO JOURNAL OF PARALLEL AND DISTRIBUTED COMPUTING LA English DT Article DE MPI; Multicore; Cluster; HPC; Collective communication; Hierarchical AB Multicore Clusters, which have become the most prominent form of High Performance Computing (HPC) systems, challenge the performance of MPI applications with non-uniform memory accesses and shared cache hierarchies. Recent advances in MPI collective communications have alleviated the performance issue exposed by deep memory hierarchies by carefully considering the mapping between the collective topology and the hardware topologies, as well as the use of single-copy kernel assisted mechanisms. However, on distributed environments, a single level approach cannot encompass the extreme variations not only in bandwidth and latency capabilities, but also in the capability to support duplex communications or operate multiple concurrent copies. This calls for a collaborative approach between multiple layers of collective algorithms, dedicated to extracting the maximum degree of parallelism from the collective algorithm by consolidating the intra- and inter-node communications. In this work, we present HierKNEM, a kernel-assisted topology-aware collective framework, and the mechanisms deployed by this framework to orchestrate the collaboration between multiple layers of collective algorithms. The resulting scheme maximizes the overlap of intra- and inter-node communications. We demonstrate experimentally, by considering three of the most used collective operations (Broadcast, Allgather and Reduction), that (1) this approach is immune to modifications of the underlying process-core binding; (2) it outperforms state-of-art MPI libraries (Open MPI, MPICH2 and MVAPICH2) demonstrating up to a 30x speedup for synthetic benchmarks, and up to a 3x acceleration for a parallel graph application (ASP); (3) it furthermore demonstrates a linear speedup with the increase of the number of cores per compute node, a paramount requirement for scalability on future many-core hardware.

In addition, there is a significant conflict between testing as part of an iterative process of finding and removing defects and testing as a means of estimating or predicting product reliability. We review the basics of these testing methods and describe how they relate to statistical methods for estimation and prediction of reliability and reliability growth. We also outline potential synergies to help reconcile statistical and engineering approaches to accelerated testing, resulting in better product quality at lower cost.

Unfortunately, nuisance alarms due to naturally occurring radioactive material (NORM) reduce detection probabilities for threat sources. This paper evaluates to what extent gamma counts for a range of energies (i.e., a gamma spectrum) deployed in primary screening can detect threat-point sources, with attention to background-suppression effects. Approach: It is assumed that most NORM sources are more spatially distributed than a point source and that most threat sources are distributed more like a point source. Therefore, we seek a high-alarm probability for vehicle profiles that exhibit a point-like shift in spectral shape. The proposed approach uses variation of the gamma spectral shape over time as a moving vehicle carrying a point source is screened. Results: The paper uses data from approximately 2000 real vehicle screenings to develop alarm thresholds and to evaluate detection probabilities of injected threat sources from both NORM and threat isotopes. It is shown that transforming the raw gamma spectra is advantageous and that using the Mahalanobis distance to detect the point-like shift in spectral shape is superior to a spectral distance used in the literature.

We compared phenotypic and genetic variation in HIV-1 env genes from subjects in acute/early infection and subjects with chronic infections in the context of subtype C heterosexual transmission. We found that the transmitted viruses all used CCR5 and required high levels of CD4 to infect target cells, suggesting selection for replication in T cells and not macrophages after transmission. In addition, the transmitted viruses were more likely to use a maraviroc-sensitive conformation of CCR5, perhaps identifying a feature of the target T cell. We confirmed an earlier observation that the transmitted viruses were, on average, modestly under-glycosylated relative to the viruses from chronically infected subjects. This difference was most pronounced in comparing the viruses in acutely infected men to those in chronically infected women. These features of the transmitted virus point to selective pressures during the transmission event. We did not observe a consistent difference either in heterologous neutralization sensitivity or in sensitivity to soluble CD4 between the two groups, suggesting similar conformations between viruses from acute and chronic infection. However, the presence or absence of glycosylation sites had differential effects on neutralization sensitivity for different antibodies. We suggest that the occasional absence of glycosylation sites encoded in the conserved regions of env, further reduced in transmitted viruses, could expose specific surface structures on the protein as antibody targets.

We followed the relaxation of a 13C tracer in fine roots in a Liquidambar styraciflua plantation at the conclusion of a free-air CO2 enrichment experiment. Goals included quantifying the relative fractions of new photosynthate vs stored C used in root growth and root respiration, as well as the turnover rate of fine-root C fixed during [CO2] fumigation. New fine-root growth was largely from recent photosynthate, while nearly one-quarter of respired C was from a storage pool. Changes in the isotopic composition of the fine-root population over two full growing seasons indicated heterogeneous C pools; <10% of root C had a residence time <3months, while a majority of root C had a residence time >2yr. Compared to a one-pool model, a two-pool model for C turnover in fine roots (with 5 and 0.37yr-1 turnover times) doubles the fine-root contribution to forest NPP (9-13%) and supports the 50% root-to-soil transfer rate often used in models.

Remarkably, the substrate promiscuity of AGMEs is quite variable. The molecular basis for such ligand promiscuity is largely unknown as there is not an obvious link between amino acid sequence or structure and the antibiotic profiles of AGMEs. To address this issue, this article presents the first kinetic and thermodynamic characterization of one of the least promiscuous AGMEs, the AG N3 acetyltransferase-IIa (AAC-IIa) and its comparison to two highly promiscuous AGMEs, the AG N3-acetyltransferase-IIIb (AAC-IIIb) and the AG phosphotransferase(3)-IIIa (APH). Despite having similar antibiotic selectivities, AAC-IIIb and APH catalyze different reactions and share no homology to one another. AAC-IIa and AAC-IIIb catalyze the same reaction and are very similar in both amino acid sequence and structure. However, they demonstrate strong differences in their substrate profiles and kinetic and thermodynamic properties. AAC-IIa and APH are also polar opposites in terms of ligand promiscuity but share no sequence or apparent structural homology. However, they both are highly dynamic and may even contain disordered segments and both adopt well-defined conformations when AGs are bound. Contrary to this AAC-IIIb maintains a well-defined structure even in apo form. Data presented herein suggest that the antibiotic promiscuity of AGMEs may be determined neither by the flexibility of the protein nor the size of the active site cavity alone but strongly modulated or controlled by the effects of the cosubstrate on the dynamic and thermodynamic properties of the enzyme.

TI Effects of nitrogen addition on soil microbial diversity and methane cycling capacity depend on drainage conditions in a pine forest soil SO SOIL BIOLOGY & BIOCHEMISTRY LA English DT Article DE Fertilization; Methane; Methanogen; Methanotroph; Microarray; Diversity; qPCR ID METHANOTROPHIC BACTERIA; ATMOSPHERIC METHANE; OXIDIZING BACTERIA; EMISSIONS; CONSUMPTION; OXIDATION; EXCHANGE; BIOGEOGRAPHY; SEDIMENTS; OXIDE AB Two forested study sites, one well and one poorly drained, were used for investigation of the effects of variation in drainage, microclimate, and addition of inorganic nitrogen (N) on the whole soil microbial community and its methane cycling capacity. Both sites were capable of consuming and releasing large quantities of methane. The composition of the soil microbial community was investigated using the 3rd generation PhyloChip, a bacterial and archaeal 16S rRNA gene microarray. The PhyloChip was also used to target the composition of methane- and some N-cycling microorganisms. Relative abundance of functional genes involved in methane production and consumption was evaluated with qPCR. Soil drainage condition determined the microbial community structure within and between sites. Greater community structure variation, richness of methanotrophs, and higher abundances of both methanotrophs and methanogens were all found in the poorly drained site, as was higher soil moisture and C content and methane release. In the poorly drained site, high N (67 kg NH4NO3 ha(-1) yr(-1)) increased methanotroph and methanogen abundance, overall taxonomic richness of Bacteria and Archaea, and richness of nitrifiers and methanotrophs. In the well drained site, high N decreased taxonomic richness. Results may indicate that high N concentrations stimulated oxidative reactions, including ammonia and methane oxidation and nitrification in the short term. The resultant increase in release of methane from the high N plots of the poorly-drained site may have been due to indirect inhibition of methane oxidation by the increase in other oxidative reactions. Alternatively, both methanogens and methanotrophs may have been stimulated by high N. Well-drained site high N decreased the taxonomic richness of the soil, but did not impact methane-cycling microbes. These findings begin to bridge the gap between microbial-scale community dynamics and ecosystem-scale ecological functions. (C) 2013 Elsevier Ltd. All rights reserved.

Owing to the ultra-short duration of each snapshot in these fluctuation scattering experiments, the particles are effectively frozen in space during the X-ray exposure. In contrast to standard small-angle scattering experiments, the resulting scattering patterns are anisotropic. The intensity fluctuations observed in the diffraction images can be used to obtain structural information embedded in the average angular correlation of the Fourier transform of the scattering species, of which standard small-angle scattering data are a subset. The additional information contained in the data of these fluctuation scattering experiments can be used to determine the structure of macromolecules in solution without imposing symmetry or spatial restraints during model reconstruction, reducing ambiguities normally observed in solution scattering studies. In this communication, a method that utilizes fluctuation X-ray scattering data to determine low-resolution solution structures is presented. The method is validated with theoretical data calculated from several representative molecules and applied to the reconstruction of nanoparticles from experimental data collected at the Linac Coherent Light Source.

We use two-photon photoemission electron microscopy (2P-PEEM) to image electron emission from a silver-capped aggregate trimer. Finite difference time domain (FDTD) simulations are performed to model the intensity distributions of the electromagnetic near fields resulting from femtosecond laser excitation of localized surface plasmon oscillations in the trimer structure. We demonstrate that the predicted FDTD near-field intensity distribution reproduces the 2P-PEEM photoemission pattern.

TI Reliability of environmental fate modeling results for POPs based on various methods of determining the air/water partition coefficient (log K-AW) SO ATMOSPHERIC ENVIRONMENT LA English DT Article DE Air-water partition coefficient; Multimedia mass modeling; QSPR; POPs ID PERSISTENT ORGANIC POLLUTANTS; MASS-BALANCE MODELS; PHYSICOCHEMICAL PROPERTIES; APPLICABILITY DOMAIN; BRITISH-COLUMBIA; TRANSPORT; PREDICTION; CANADA; BIOACCUMULATION; PARAMETERS AB Air-water partition coefficient (K-AW) is one of the key parameters determining environmental behavior of Persistent Organic Pollutants (POPs). Experimentally measured values of K-AW are still unavailable for majority of POPs, thus alternative methods of supplying data, including Quantitative Structure-Property Relationships (QSPR) modeling, are often in use. In this paper, applicability of two QSPR methods of predicting K-AW were compared with each other in the context of further application of the predicted data in environmental transport and fate studies. According to the first (indirect) method, K-AW is calculated from previously predicted values of octanol-water (K-OW) and octanol-air (K-OA) partition coefficients. In the second (direct) approach, K-AW is calculated, based on the estimated value of Henry's law constant (K-H) and then adjusted to ensure its consistency with the other two partition coefficients (K-OW and K-OA). Although the indirect method carries theoretically twice as much error as the direct method, when the predicted values of K-AW are then utilized as an input to the environmental fate model The OECD P-OV and LRTP Screening Tool, ver. 2.2, the indirect method elicits much higher and therefore much more restrictive values of overall persistence (P-OV) and transfer efficiency (TE) than its equivalent (direct method). High uncertainties related to the application of the direct method result mainly from the necessary adjustment procedure. (C) 2013 Published by Elsevier Ltd.

Using a 2-years data record, the impacts of the shutdown of the CFPP on nearby ambient concentrations of three Hg species were quantified. The arithmetic average ambient concentrations of gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM), and particulate mercury (PBM) during December 2007-November 2009 were 1.6 ng m(-3), 5.1 pg m(-3), and 8.9 pg m(-3) respectively. The median concentrations of GEM, GOM, and PBM significantly decreased by 12%, 73%, and 50% after the CFPP closed (Mann-Whitney test, p < 0.001). Positive Matrix Factorization (EPA PMF v4.1) identified six factors including O-3-rich, traffic, gas phase oxidation, wood combustion, nucleation, and CFPP. When the CFPP was closed, median concentrations of GEM, GOM, and PBM apportioned to the CFPP factor significantly decreased by 25%, 74%, and 67%, respectively, compared to those measured when the CFPP was still in operation (Mann-Whitney test, p < 0.001). Conditional probability function (CPF) analysis showed the greatest reduction in all three Hg species was associated with northwesterly winds pointing toward the CFPP. These changes were clearly attributable to the closure of the CFPP. (c) 2013 Elsevier Ltd. All rights reserved.

TI Assessment of diffraction-enhanced synchrotron imaging for cartilage degeneration of the human knee joint SO CLINICAL ANATOMY LA English DT Article DE diffraction-enhanced imaging; cartilage imaging; synovial joints; osteoarthritis ID ARTICULAR-CARTILAGE; OSTEOARTHRITIS; RADIOGRAPHY; LESIONS; BONE AB Diffraction-enhanced imaging (DEI) is a radiographic technology that harnesses the X-ray refraction and scatter rejection properties that are not available with conventional radiography. Here, we test the efficacy of planar DEI to render images from which cartilage degeneration, characteristic of osteoarthritis, can be detected. DEI was carried out on human cadaveric intact knee joints at the X-15 beamline at the National Synchrotron Light Source. The gross specimens and the DEI images were graded separately for levels of cartilage degeneration on six individual surfaces: anterior and posterior femoral and tibial on both medial and lateral sides. There was a significant correlation between the actual levels of cartilage degeneration and what was observed in their respective DEI images (P < 0.05) for all six articular surfaces. Some articular surfaces (patellar surfaces, in particular) could not be visualized because of overlap with superimposed bone. Sensitivity for the graded articular surfaces was 0.73 and specificity was 0.92 (Grade 0 being no lesion and Grades 1-6 being increasing gradations of lesions). Chondrocalcinosis was also observed in DEI images to a far greater extent compared with the conventional radiographs. DEI renders images that are significantly correlated with their actual gross morphology. Detection of lesions was better for more severe grades of degeneration than for partial focal lesions. Although some articular surfaces could not be visualized because of superimposed bone, we feel that DEI has potential for the diagnosis of cartilage lesions and chondrocalcinosis. Clin.

Sera from CD patients were used to select immunoreactive antigens from a cDNA phage-display library. Candidate genes were identified, the corresponding protein's produced and their immunoreactivity validated With sera from CD patients and controls. Thirteen CD-specific antigens were identified and further validated by protein microarray. The specificity for 6 of these antigens was confirmed by ELISA. Furthermore we showed that this antibody response was not abolished on a gluten free diet and was not shared with other autoimmune diseases. These antigens appear to be CD specific and independent of gluten induction. The utility of this panel extends beyond its diagnostic value and it may drive the attention to new targets for unbiased screens in autoimmunity research. (C) 2013 Elsevier Inc. All rights reserved.

This segmentation helps to reduce the number of cases where sampling in transfer function space should be performed, effectively reducing the rendering cost for equivalent sampling quality.

However, existing algorithms to compute the MS complex are restricted to either piecewise linear or discrete scalar fields. This paper presents a new combinatorial algorithm to compute MS complexes for two-dimensional piecewise bilinear functions defined on quadrilateral meshes. We derive a new invariant of the gradient flow within a bilinear cell and use it to develop a provably correct computation, unaffected by numerical instabilities. This includes a combinatorial algorithm to detect and classify critical points as well as a way to determine the asymptotes of cell-based saddles and their intersection with cell edges. Finally, we introduce a simple data structure to compute and store integral lines on quadrilateral meshes which by construction prevents intersections and allows to enforce constraints on the gradient flow that preserve known invariants.

We then use information from the triangulation and its dual Voronoi complex to determine for each face whether it resembles a boundary or interior face, allowing a user to choose a specific segmentation by keeping only faces where our parameter is above a threshold.

Even though a significant amount of research has been directed to defining and extracting ridges some fundamental challenges remain. For example, the most popular ridge definition (height ridge) is not invariant under monotonic transformations and its global structure is typically ignored during numerical computations. Furthermore, many existing algorithms are based on numerical heuristics and are rarely guaranteed to produce consistent results. This paper reexamines a slightly different ridge definition that is consistent with all desired invariants. Nevertheless, we show that this definition results in similar structures compared to height ridges and that both formulations are equivalent for quadratic functions. Furthermore, this definition can be cast in the form of a degenerate Jacobi set, which allows insights into the global structure of ridges. In particular, we introduce the Ridge-Valley graph as the complete description of all ridges in an image. Finally, using the connection to Jacobi sets we describe a new combinatorial algorithm to extract the Ridge-Valley graph from sampled images guaranteed to produce a valid structure.

TI Influence of oxic/anoxic fluctuations on ammonia oxidizers and nitrification potential in a wet tropical soil SO FEMS MICROBIOLOGY ECOLOGY LA English DT Article DE nitrifiers; Puerto Rico; redox oscillation; oxygen depletion; archaea; amoA AB Ammonia oxidation is a key process in the global nitrogen cycle. However, in tropical soils, little is known about ammonia-oxidizing microorganisms and how characteristically variable oxygen regimes affect their activity. We investigated the influence of brief anaerobic periods on ammonia oxidation along an elevation, moisture, and oxygen availability gradient in wet tropical soils. Soils from three forest types were incubated for up to 36weeks in lab microcosms under three regimes: (1) static aerobic; (2) static anaerobic; and (3) fluctuating (aerobic/anaerobic). Nitrification potential was measured in field-fresh soils and incubated soils. The native ammonia-oxidizing community was also characterized, based on diversity assessments (clone libraries) and quantification of the ammonia monooxygenase -subunit (amoA) gene. These relatively low pH soils appear to be dominated by ammonia-oxidizing archaea (AOA), and AOA communities in the three soil types differed significantly in their ability to oxidize ammonia. Soils from an intermediate elevation, and those incubated with fluctuating redox conditions, tended to have the highest nitrification potential following an influx of oxygen, although all soils retained the capacity to nitrify even after long anoxic periods. Together, these results suggest that wet tropical soil AOA are tolerant of extended periods of anoxia. C1 [Pett-Ridge, Jennifer] Lawrence Livermore Natl Lab, Livermore, CA 94551 USA.

Using a remotely operated vessel, we characterized the bathymetry and near-surface temperatures at sub-meter resolution. The majority of the 1.2ha, pH 2.2 lake is 10m deep and 50-52 degrees C, but temperatures reach 93 degrees C locally. We extracted DNA from water and sediments collected from warm (52 degrees C) and hot (73-83 degrees C) sites separated by 180m. Gene clone libraries and functional gene microarray (GeoChip 3.0) were used to investigate the BSL community, and uptake of radiolabeled carbon sources was used to assess the relative importance of heterotrophic vs. autotrophic production. Microbial assemblages are similar in both sites despite the strong temperature differential, supporting observations of a dynamic, convectively mixed system. Bacteria in the Actinobacteria and Aquificales phyla are abundant in the water column, and Archaea distantly related to known taxa are abundant in sediments. The functional potential appears similar across a 5-year time span, indicating a stable community with little inter-annual variation, despite the documented seasonal temperature cycle. BSL water-derived DNA contains genes for complete C, N, and S cycles, and low hybridization to probes for N and S oxidation suggests that reductive processes dominate. Many of the detected genes for these processes were from uncultivated bacteria, suggesting novel organisms are responsible for key ecosystem services. Selection imposed by low nutrients, low pH, and high temperature appear to result in low diversity and evenness of genes for key functions involved in C, N, and S cycling. Conversely, organic degradation genes appear to be functionally redundant, and the rapid assimilation of radiolabeled organic carbon into BSL cells suggests the importance of allochthonous C fueling heterotrophic production in the BSL C cycle.

This class of catalysts has relatively low turnover frequencies for oxygen reduction reaction (ORR) when compared to platinum. One way to compensate for it is to increase the catalyst site density. In this work, a model system for a high site density catalytic layer for polymer electrolyte fuel cells was synthesized and characterized. Dipyrromethane was electropolymerized on glassy carbon and glass/ITO electrodes to form a ligand matrix of up to 200 nm in thickness, to which, cobalt was introduced during the electropolymerization process. Thin polymeric sheets were observed after the electrochemical synthesis and the cobalt density in the matrix was found to be 9.84 x 10(21) cobalt atoms cm(-3). ORR activity was demonstrated with oxygen reduction occurring at E-1/2 = 0.45 V and has an onset potential of 0.62 V vs. RHE. (C) 2013 Elsevier B.V. All rights reserved.

This has become a bottleneck in designing bioenergy crops. The goal of this study was to analyze the regulation of plant cell wall precursor metabolism using metabolic flux analysis based on dynamic labeling experiments. Arabidopsis T87 cells were cultured heterotrophically with C-13 labeled sucrose. The time course of C-13 labeling patterns in cell wall precursors and related sugar phosphates was monitored using liquid chromatography tandem mass spectrometry until steady state labeling was reached. A kinetic model based on mass action reaction mechanisms was developed to simulate the carbon flow in the cell wall synthesis network. The kinetic parameters of the model were determined by fitting the model to the labeling time course data, cell wall composition, and synthesis rates. A metabolic control analysis was performed to predict metabolic regulations that may improve plant biomass composition for biofuel production. Our results describe the routes and rates of carbon flow from sucrose to cell wall precursors. We found that sucrose invertase is responsible for the entry of sucrose into metabolism and UDP-glucose-4-epimerase plays a dominant role in UDP-Gal synthesis in heterotrophic Aradidopsis cells under aerobic conditions. We also predicted reactions that exert strong regulatory influence over carbon flow to cell wall synthesis and its composition. (C) 2013 Elsevier Inc. All rights reserved.

Evidence supports its widespread presence in indoor environments. However, its genotoxic potential, a critical aspect in risk assessment, is virtually untested. An important characteristic of THS is its ability to undergo chemical transformations during aging periods, as demonstrated in a recent study showing that sorbed nicotine reacts with the indoor pollutant nitrous acid (HONO) to form tobacco-specific nitrosamines (TSNAs) such as 4-(methylnitrosamino)-4-(3-pyridyl)butanal (NNA) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). The goal of this study was to assess the genotoxicity of THS in human cell lines using two in vitro assays. THS was generated in laboratory systems that simulated short (acute)- and long (chronic)-term exposures. Analysis by liquid chromatographytandem mass spectrometry quantified TSNAs and common tobacco alkaloids in extracts of THS that had sorbed onto cellulose substrates. Exposure of human HepG2 cells to either acute or chronic THS for 24h resulted in significant increases in DNA strand breaks in the alkaline Comet assay. Cell cultures exposed to NNA alone showed significantly higher levels of DNA damage in the same assay. NNA is absent in freshly emitted secondhand smoke, but it is the main TSNA formed in THS when nicotine reacts with HONO long after smoking takes place. The long ampliconquantitative PCR assay quantified significantly higher levels of oxidative DNA damage in hypoxanthine phosphoribosyltransferase 1 (HPRT) and polymerase (POLB) genes of cultured human cells exposed to chronic THS for 24h compared with untreated cells, suggesting that THS exposure is related to increased oxidative stress and could be an important contributing factor in THS-mediated toxicity. The findings of this study demonstrate for the first time that exposure to THS is genotoxic in human cell lines.

SO NICOTINE & TOBACCO RESEARCH LA English DT Article ID ENVIRONMENTAL TOBACCO-SMOKE; BARS; RESTAURANTS; HEALTH; CAFES; PUBS AB Secondhand smoke (SHS) exposure continues to be a problem in bars and restaurants where smoking is permitted. This study measures the relative SHS exposure reduction in nonsmoking sections of establishments that allow some smoking. Measurements were conducted simultaneously in the smoking and nonsmoking sections of 14 Minnesota hospitality venues. All of the 16 two-hr visits included photometer measurements of fine particles (PM2.5) and 12 of the visits also included measurements of 4 gas-phase tracers of SHS. The median ratio of nonsmoking/smoking section PM2.5 concentrations was 0.65 with an interquartile range (IQR) of 0.490.72. Measurements conducted after implementation of a smoking ban at 13 of the venues resulted in a smoking section PM2.5 post-ban/pre-ban ratio of 0.06 (IQR 0.020.16). The median nonsmoking/smoking section ratios for gas-phase compound were 0.67 (IQR 0.350.78) for pyridine, 0.52 (IQR 0.300.70) for pyrrole, 0.43 (IQR 0.350.84) for 3-EP, and 0.27 (IQR 0.160.47) for nicotine. These results are consistent with the expectations of differential removal: the lowest ratios are for the least volatile, most strongly sorbing gases and the highest ratios for less sorbing gases and PM2.5. Designated nonsmoking sections in establishments that allow some smoking resulted in a median PM2.5 reduction of 35% compared with a 94% reduction after a smoking ban. The only adequate protection from cigarette smoke exposure is to eliminate smoking in indoor spaces.

The scattering model used here is based on the work of Bonoli and Ott (1982 Phys. Fluids 25 361). It utilizes an electromagnetic wave kinetic equation solved by a Monte Carlo technique. This scattering model has been implemented in GENRAY, a ray-tracing code which explicitly simulates wave propagation, as well as collisionless and collisional damping processes, over the entire plasma discharge, including the scrape-off layer that extends from the separatrix to the vessel wall. A numerical analysis of the LH wave trajectories and the power deposition profile with and without scattering is presented for Alcator C-Mod discharges. Comparisons between the measured hard x-ray emission on Alcator C-Mod and simulations of the data obtained from the synthetic diagnostic included in the GENRAY/CQL3D package are shown, with and without the combination of scattering and collisional damping. Implications of these results on LH current drive are discussed. C1 [Bertelli, N.; Phillips, C. K.; Valeo, E. J.; Wilson, J. R.] Princeton Plasma Phys Lab, Princeton, NJ 08543 USA.

These states, called quasi-single helicity (QSH) states, are characterized by the action of a MHD mode that impresses a quasi-helical symmetry to the system, thus allowing a high degree of magnetic chaos healing. This is in contrast with the multiple helicity (MH) states, where magnetic fluctuations create a chaotic magnetic field degrading the confinement properties of the RFP. This paper reports an extensive numerical study performed in the frame of 3D visco-resistive MHD which considers the effect of helical magnetic boundary conditions, i.e. of a finite value of the radial magnetic field at the edge (magnetic perturbation, MP). We show that the system can be driven to a selected QSH state starting from both spontaneous QSH and MH regimes. In particular, a high enough MP can force a QSH helical self-organization with a helicity different from the spontaneous one. Moreover, MH states can be turned into QSH states with a selected helicity. A threshold in the amplitude of MP is observed above which is able to influence the system. Analysis of the magnetic topology of these simulations indicates that the dominant helical mode is able to temporarily sustain conserved magnetic structures in the core of the plasma. The region occupied by conserved magnetic surfaces increases reducing secondary modes' amplitude to experimental-like values.

Our strategy was to incorporate zinc at the designed interface to promote affinity and orientation specificity. A large set of monomeric scaffold surfaces were computationally engineered with three-residue zinc coordination sites, and the ubiquitin residue H68 was docked to the open coordination site to complete a tetrahedral zinc site. This single coordination bond was intended as a hotspot and polar interaction for ubiquitin binding, and surrounding residues on the scaffold were optimized primarily as hydrophobic residues using a rotamer-based sequence design protocol in Rosetta. From thousands of independent design simulations, four sequences were selected for experimental characterization. The best performing design, called Spelter, binds tightly to zinc (Kd<10 nM) and binds ubiquitin with a Kd of 20 mu M in the presence of zinc and 68 mu M in the absence of zinc. Mutagenesis studies and nuclear magnetic resonance chemical shift perturbation experiments indicate that Spelter interacts with H68 and the target surface on ubiquitin; however, H68 does not form a hotspot as intended. Instead, mutation of H68 to alanine results in tighter binding. Although a 3/1 zinc coordination arrangement at an interface cannot be ruled out as a means to improve affinity, our study led us to conclude that 2/2 coordination arrangements or multiple-zinc designs are more likely to promote high-affinity protein interactions.

The microvalves rely on transducers that convert electrical signals into mechanical forces, and the miniaturization and integration of these transducers has proven to be challenging. Here, we report a strategy for operating pneumatic valves where microscale electrostatic actuators were used to relay commands from electronic ancillaries. Each electrostatic actuator occupied a footprint less than 0.5 mm(2), and was composed entirely of poly(dimethylsiloxane) and multi-walled carbon nanotubes. Similar to typical pneumatic microvalves, the electrostatic actuators were fabricated exclusively with soft-lithographic techniques, which permitted both components to be integrated monolithically. The actuators operated at electric potentials less than 300V, and regulated microchannels pressurized up to similar to 4 kPa, which is sufficient for many microfluidic applications.

Developed some 40 years ago, bioactive glass (BG) has recently become one of the most promising biomaterials, a consequence of discoveries that its unusual properties elicit specific biological responses inside the body. Among these important properties are the capability of BG to form strong interfaces with both hard and soft tissues, and its release of ions upon dissolution. Recent developments in nanotechnology have introduced opportunities for materials sciences to advance dental and bone therapies. For example, the applications for BG expand as it becomes possible to finely control structures and physicochemical properties of materials at the molecular level. Here, we review how the properties of these materials have been enhanced by the advent of nanotechnology, and how these developments are producing promising results in hard-tissue regeneration and development of innovative BG-based drug delivery systems.

TI Enriching pathogen transcripts from infected samples: A capture-based approach to enhanced host-pathogen RNA sequencing SO ANALYTICAL BIOCHEMISTRY LA English DT Article DE Capture; RNA-Seq; Transcript enrichment; Next-generation sequencing; Rift Valley fever virus; Francisella tularensis ID FRANCISELLA-TULARENSIS; VIRULENCE; SYSTEMS; CELLS; CHROMATOGRAPHY; EXPRESSION; MODEL; SEQ; DNA AB To fully understand the interactions of a pathogen with its host, it is necessary to analyze the RNA transcripts of both the host and pathogen throughout the course of an infection. Although this can be accomplished relatively easily on the host side, the analysis of pathogen transcripts is complicated by the overwhelming amount of host RNA isolated from an infected sample. Even with the read depth provided by second-generation sequencing, it is extremely difficult to get enough pathogen reads for an effective gene-level analysis. In this study, we describe a novel capture-based technique and device that considerably enriches for pathogen transcripts from infected samples. This versatile method can, in principle, enrich for any pathogen in any infected sample. To test the technique's efficacy, we performed time course tissue culture infections using Rift Valley fever virus and Francisella tularensis. At each time point, RNA sequencing (RNA-Seq) was performed and the results of the treated samples were compared with untreated controls. The capture of pathogen transcripts, in all cases, led to more than an order of magnitude enrichment of pathogen reads, greatly increasing the number of genes hit, the coverage of those genes, and the depth at which each transcript was sequenced.

We combined process-based and geospatial models to estimate the potential biomass productivity of miscanthus and its potential impact on soil carbon stocks in the croplands of the continental United States. The optimum (climatic potential) rainfed productivity for field-dried miscanthus biomass ranged from 1 to 23Mgbiomassha-1yr-1, with a spatial average of 13Mgha-1yr-1 and a coefficient of variation of 30%. This variation resulted primarily from the spatial heterogeneity of effective rainfall, growing degree days, temperature, and solar radiation interception. Cultivating miscanthus would result in a soil organic carbon (SOC) sequestration at the rate of 0.16-0.82MgCha-1yr-1 across the croplands due to cessation of tillage and increased biomass carbon input into the soil system. We identified about 81millionha of cropland, primarily in the eastern United States, that could sustain economically viable (>10Mgha-1yr-1) production without supplemental irrigation, of which about 14millionha would reach optimal miscanthus growth. To meet targets of the US Energy Independence and Security Act of 2007 using miscanthus as feedstock, 19millionha of cropland would be needed (spatial average 13Mgha-1yr-1) or about 16% less than is currently dedicated to US corn-based ethanol production.

TI Performance and cycling of the iron-ion/hydrogen redox flow cell with various catholyte salts SO JOURNAL OF APPLIED ELECTROCHEMISTRY LA English DT Article DE Redox flow cell; Flow battery; Iron hydrogen cell ID BATTERY; PROGRESS AB A redox flow cell utilizing the Fe2+/Fe3+ and H-2/H+ couples is investigated as an energy storage device. A conventional polymer electrolyte fuel cell anode and membrane design is employed, with a cathode chamber containing a carbon felt flooded with aqueous acidic solution of iron salt. The maximum power densities achieved for iron sulfate, iron chloride, and iron nitrate are 148, 207, and 234 mW cm(-2), respectively. It is found that the capacity of the iron nitrate solution decreases rapidly during cycling. Stable cycling is observed for more than 100 h with iron chloride and iron sulfate solutions. Both iron sulfate and iron chloride solutions display moderate discharge polarization and poor charge polarization; therefore, voltage efficiency decreases dramatically with increasing current density. A small self-discharge current occurs when catholyte is circulating through the cathode chamber. As a result, a current density above 100 mA cm(-2) is required to achieve high Coulombic efficiency (> 0.9).

To better understand the interplay of forces near this critical temperature, cryogenic scanning electron microscopy (cryoSEM) was used to track the latex particle deformation and water migration in coatings dried at temperatures just above and below the MFFT. Although the latex particles completely coalesced at both temperatures by the end of the drying process, it was discovered that particle deformation during the early drying stages was drastically different. Below the MFFT, cracks initiated just as menisci began to recede into the packing of consolidated particles, whereas above the MFFT, partial particle deformation occurred before menisci entered the coating and cracks were not observed. The spacing between cracks measured in coatings dried at varying temperatures decreased with decreasing drying temperature near the MFFT, whereas it was independent of temperature below a critical temperature. Finally, the addition of small amounts of silica aggregates was found to lessen the cracking of latex coatings near the MFFT without adversely affecting their optical clarity.

TI Whole Genome Pyrosequencing of Rare Hepatitis C Virus Genotypes Enhances Subtype Classification and Identification of Naturally Occurring Drug Resistance Variants SO JOURNAL OF INFECTIOUS DISEASES LA English DT Article DE Hepatitis C virus; pyrosequencing; subtype classification; drug resistance mutations; viral diversity ID OPEN READING FRAME; NS3 PROTEASE; POLYMERASE INHIBITORS; MAXIMUM-LIKELIHOOD; ST-PETERSBURG; IN-VITRO; HCV-RNA; RECOMBINANT; TMC435; SEQUENCES AB Background. Infection with hepatitis C virus (HCV) is a burgeoning worldwide public health problem, with 170 million infected individuals and an estimated 20 million deaths in the coming decades. While 6 main genotypes generally distinguish the global geographic diversity of HCV, a multitude of closely related subtypes within these genotypes are poorly defined and may influence clinical outcome and treatment options. Unfortunately, the paucity of genetic data from many of these subtypes makes time-consuming primer walking the limiting step for sequencing understudied subtypes. Methods. Here we combined long-range polymerase chain reaction amplification with pyrosequencing for a rapid approach to generate the complete viral coding region of 31 samples representing poorly defined HCV subtypes. Results. Phylogenetic classification based on full genome sequences validated previously identified HCV subtypes, identified a recombinant sequence, and identified a new distinct subtype of genotype 4. Unlike conventional sequencing methods, use of deep sequencing also facilitated characterization of minor drug resistance variants within these uncommon or, in some cases, previously uncharacterized HCV subtypes. Conclusions. These data aid in the classification of uncommon HCV subtypes while also providing a high-resolution view of viral diversity within infected patients, which may be relevant to the development of therapeutic regimens to minimize drug resistance.

The linear response theory of a noninteracting Fermi gas is reviewed and several consistency constraints are verified. The challenge to formulate linear response theories of BCS superfluids consistent with density and spin conservation laws comes from the presence of a broken U(1)(EM) symmetry associated with electromagnetism (EM) and we discuss two routes for circumventing this. The first route follows Nambu's integral-equation approach for the EM vertex function, but this method is not specific for BCS superfluids. We focus on the second route based on a consistent-fluctuation-of-the order-parameter (CFOP) approach where the gauge transformation and the fluctuations of the order parameter are treated on equal footing. The CFOP approach allows one to explicitly verify several important constraints: The EM vertex satisfies not only a Ward identity which guarantees charge conservation but also a Q-limit Ward identity associated with the compressibility sum rule. In contrast, the spin degrees of freedom associated with another U(1) (z) symmetry are not affected by the Cooper-pair condensation that breaks only the U(1)(EM) symmetry. As a consequence the collective modes from the fluctuations of the order parameter only couple to the density response function but decouple from the spin response function, which reflects the different fates of the two U(1) symmetries in the superfluid phase. Our formulation lays the ground work for applications to more general theories of BCS-Bose Einstein Condensation (BEC) crossover both above and below T (c) .

TI The role of three-nucleon forces and many-body processes in nuclear pairing SO JOURNAL OF PHYSICS G-NUCLEAR AND PARTICLE PHYSICS LA English DT Article ID LOW-MOMENTUM INTERACTIONS; SHELL-MODEL; PHASE AB We present microscopic valence-shell calculations of pairing gaps in the calcium isotopes, focusing on the role of three-nucleon (3N) forces and many-body processes. In most cases, we find a reduction in pairing strength when the leading chiral 3N forces are included, compared to results with low-momentum two-nucleon (NN) interactions only. This is in agreement with a recent energy density functional study. At the NN level, calculations that include particle-particle and hole-hole ladder contributions lead to smaller pairing gaps compared with experiment. When particle-hole contributions as well as the normal-ordered one- and two-body parts of 3N forces are consistently included to third order, we find reasonable agreement with experimental three-point mass differences. This highlights the important role of 3N forces and many-body processes for pairing in nuclei. Finally, we relate pairing gaps to the evolution of nuclear structure in neutron-rich calcium isotopes and study the predictions for the 2(+) excitation energies, in particular for Ca-54.

We design a middleware layer of high-speed communication based on Remote Direct Memory Access (RDMA) that serves as the common substrate to accelerate various data transfer tools, such as FTP, HTTP, file copy, sync and remote file I/O. This middleware offers better end-to-end bandwidth performance than the traditional TCP-based alternatives, while it hides the heterogeneity of the underlying high-speed architecture. This paper describes this middleware's function modules, including resource abstraction and task synchronization and scheduling, that maximize the parallelism and performance of RDMA operations. For networks without RDMA hardware acceleration, we integrate Linux kernel optimization techniques to reduce data copy and processing in the middleware. We provide a reference implementation of the popular file-transfer protocol over this RDMA-based middleware layer, called RFTP. Our experimental results show that our RFTP outperforms several TCP-based FTP tools, such as GridFTP, while it maintains very low CPU consumption on a variety of data center platforms. Furthermore, those results confirm that our RFTP tool achieves near line-speed performance in both LAN and WAN, and scales consistently from 10 Gbps Ethernet to 40 Gbps Ethernet and InfiniBand environments.

TI Oxidation behaviour of cast Ni-Cr alloys in steam at 800 degrees C SO MATERIALS SCIENCE AND TECHNOLOGY LA English DT Article DE Steam oxidation; Cast Ni base alloys; Internal oxidation ID HIGH-TEMPERATURE OXIDATION; WATER-VAPOR; INTERNAL OXIDATION; BASE ALLOYS; MATERIALS TECHNOLOGY; FORMING ALLOYS; CORROSION; SCALES; PLANTS; EVAPORATION AB To evaluate the steam oxidation resistance of cast Ni base alloy candidates for advanced steam turbine casings, laboratory experiments were conducted at 800 degrees C. Alloys ranged from weaker, solid solution strengthened alloys 230 and 625 to stronger, precipitation strengthened alloys 105, 263 and 740, which are more difficult to fabricate and join. In general, these Ni-Cr based alloys exhibit low mass gains and form thin, protective Cr rich external oxides in 17 bar steam or 1 bar air. However, Al and Ti in these alloys internally oxidise in all cases. After 5000 h exposures, the average and maximum internal oxide penetration depths were measured, and the values were ranked based on the alloy Al + Ti contents. The middle range of Al + Ti compositions investigated, such as for alloys 617, 263, 282 and 740, showed the deepest penetrations. Further characterisation of the reaction products by electron microprobe showed a complex behaviour including significant Ti incorporation into the scale formed in both steam and air, and Ti rich oxide at both the gas and metal interfaces. Based on the Al and Ti contents, the internal oxidation observed in these alloys in steam was atypical. C1 [Essuman, E.; Walker, L. R.; Maziasz, J.; Pint, B.

The first series of experiments examined Pt diffusion and Pt modified aluminised bond coatings on second generation superalloy N5 at 1150 degrees C with commercially vapour deposited yttria stabilised zirconia (YSZ) top coats. Compared to dry O-2, the average lifetimes with Pt diffusion coatings were unaffected by the addition of water vapour, while the Pt modified aluminide coating average lifetime was reduced by >50% with 10% water vapour, but less reduction was observed with higher water contents. The second series of experiments examined MCrAlY and MCrAlYHfSi bond coatings and air plasma sprayed YSZ top coatings on superalloy X4 cycled at 1100 degrees C. Compared to dry O-2, the addition of 10% water vapour decreased the lifetime of MCrAlY by 28%. Higher average lifetimes were observed with Hf in the bond coating. C1 [Pint, B. A.; Haynes, J.

Microbial communities were analyzed using bacterial and archaeal 16S rRNA gene clone libraries (Sanger sequences) and 454 pyrosequencing technology. While seasonal changes in microbial community composition were observed, the significant (P = 0.001) changes in bacterial and archaeal communities were consistent with variations in ammonium concentration. Phylogenetic analysis of 16S rRNA gene sequences revealed an increase of potential ammonium-oxidizing bacteria (AOB), Nitrosomonas, Nitrosococcus, Planctomycetes, and OD1, in samples with elevated ammonium concentration. Other bacteria, such as Nitrospira, Nitrococcus, Nitrobacter, Thiobacillus, epsilon-Proteobacteria, Firmicutes, and Acidobacteria, which play roles in nitrification and denitrification, were also detected. The AOB oxidized 56 % of the ammonium with the concomitant increase in nitrite and ultimately nitrate in the trickling filters at the beginning of the treatment system. Thermoprotei within the phylum Crenarchaeota thrived in the splitter box and especially in zero-valent iron extraction trenches, where an additional 25 % of the ammonium was removed. The potential ammonium-oxidizing Archaea (AOA) (Candidatus Nitrosocaldus) were detected towards the downstream end of the treatment system. The design of an integrated treatment system consisting of trickling filters, zero-valent iron reaction cells, settling pond, and anaerobic wetlands was efficient for the biological removal of ammonium and several other contaminants from wastewater generated at a coal burning power plant equipped with selective catalytic reducers for nitrogen oxide removal.

In the reservoir, there is a large entrance effect produced by turbulence. In the pipe, the code computed turbulent velocity profiles and Reynolds stresses similar to fully developed single phase turbulent flow. The Fanning friction factor for oil flow at a Reynolds number of about 16,000 is 0.004, compared with the single phase turbulent friction factor of 0.007. The computed low frequency oscillations are consistent with wild well behavior. (C) 2013 Elsevier B.V. All rights reserved. C1 [Gidaspow, Dimitri; Li, Fang] IIT, Chicago, IL 60616 USA.

(PSRI). The risers were operated at moderate to high particle concentrations (solid fluxes up to 400 kg/m(2)s). The NETL riser was operated in the core-annulus regime. The PSRI riser was operated in both the core-annulus and dense up-flow regimes. HDPE particles with a mean diameter of 800 pm were used in the NETL riser and FCC particles with a mean diameter of 80 pm were used in the PSRI riser. Particle velocities were measured with a high speed particle imaging velocimetry (HSPIV) system developed by the NETL. The HSPIV measurement technique has the ability to measure the velocities and trajectories of thousands of particles simultaneously in flows of high particle concentration. In this study, particle velocities are measured in a small two-dimensional field-of-view with dimensions in the range of 1-5 mm wide by 1-10 mm high, with a depth of about 1 mm. The size of the field-of-view is chosen to be similar to the size of CFD grid cells in models used by NETL and small enough that gradients of the mean particle velocity are small over the field-of-view, but large enough to achieve high data sample rates (at least ten velocity vectors per camera frame). In this study sample rates for particle velocity vectors were in the range of 0.1 to 1 million per second. This sample rate provides the high temporal resolution necessary to resolve the complete temporal domain of particle velocity. Particle velocities in each camera frame (at each point in time) are averaged to yield a pointwise instantaneous particle velocity. Using a recently developed particle velocity decomposition technique (Gopalan and Shaffer, 2011 [15]) the pointwise particle velocity time series is decomposed into a varying mean Eulerian component and a random fluctuating component. Statistics of the Eulerian velocity, namely the mean, RMS, skewness and kurtosis, and the granular temperature of the random fluctuating component are presented in this study. Results show that the vertical component of the overall mean Eulerian velocity decreases with increasing mass flux in both the core-annulus and dense up-flow regimes. The root mean square (RMS) of the Eulerian velocity in the horizontal direction is independent of the radial location in the NETL riser. In the PSRI riser, for both the core-annulus and dense upflow regime, the RMS of the horizontal Eulerian velocity decreases monotonically from the center of the riser to the wall. The radial profile of the RMS of the vertical Eulerian velocity for the PSRI riser is parabolic with a peak near r/R similar to 0.5-0.6 for the dense upflow regime. For the core-annulus regime the radial profile of the RMS of the vertical Eulerian velocity is relatively flat for both the NETL and PSRI risers, with a slight decrease near the wall in the PSRI riser. The skewness of the PDF of Eulerian velocity is near zero in the horizontal direction for the dense upflow regime in the PSRI riser, the only Eulerian velocity distribution for which the Gaussian approximation is appropriate. The skewness trends of the vertical velocity distribution are more complex and require further experimental confirmation. The kurtosis of the PDF of the Eulerian velocity is always higher in the horizontal direction than the vertical direction except at the wall of the riser. The 80 mu m FCC particles in the PSRI riser showed much higher granular temperature than the 800 mu m particles in the NETL riser. The granular temperature decreases monotonically for all conditions from the center of the riser to the wall, granular temperature is anisotropic for all conditions in both risers. The radial profile of anisotropy of granular temperature is relatively flat over most of the NETL and PSRI risers with values in the range of 0.3 to 0.6. Near the wall it decreases for the PSRI riser, while increasing for the NETL riser. (C) 2013 Published by Elsevier B.V. C1 [Gopalan, Balaji] Oak Ridge Inst Sci & Educ, Oak Ridge, TN USA.

There is a growing interest in accounting for the influence of uncertainties associated with physical systems to increase the reliability of computational simulation based engineering analysis. The U.S. Department of Energy's National Energy Technology laboratory (NETL) has recently undertaken an initiative to characterize uncertainties associated with computer simulation of reacting multiphase flows encountered in energy producing systems such as a coal gasifier. The current work presents the preliminary results in applying non-intrusive parametric uncertainty quantification and propagation techniques with NETL's open-source multiphase computational fluid dynamics software MFIX For this purpose an open-source uncertainty quantification toolkit, PSUADE developed at the Lawrence Livermore National Laboratory (LLNL) has been interfaced with MFIX software. In this study, the sources of uncertainty associated with numerical approximation and model form have been neglected, and only the model input parametric uncertainty with forward propagation has been investigated by constructing a surrogate model based on data-fitted response surface for a multiphase flow demonstration problem. Monte Carlo simulation was employed for forward propagation of the aleatory type input uncertainties. Several insights gained based on the outcome of these simulations are presented such as how inadequate characterization of uncertainties can affect the reliability of the prediction results. Also a global sensitivity study using Sobol' indices was performed to better understand the contribution of input parameters to the variability observed in response variable. (C) 2013 Elsevier B.V.

Various measurement techniques have been applied in an attempt to better understand the fundamentals of the complex gas-solid flow structures that form in fluidized beds. This information may potentially provide a better design, scale-up, and operation of these systems as well as lead to accurate performance predictions of multiphase flow systems. Electrical Capacitance Volume Tomography (ECVT) has now reached a point of development where these multiphase flow structures can be imaged accurately and reliably in three dimensions at good resolutions and sampling rates to provide significant insight into the internal gas-solid flow structures. A 10 cm ECVT sensor was used in order to investigate the bubble behavior of a 10 cm diameter bubbling fluidized bed (BFB) of 185 micron glass beads at various fluidization velocities. Three dimensional images of gas-solid flow structures as well as time average vertical and radial solid fraction profiles are presented in this paper, and average bubble diameter and bubble frequency are discussed and compared to various correlations available in the published literature.

TI Standpipe models for diagnostics and control of a circulating fluidized bed SO POWDER TECHNOLOGY LA English DT Article DE Circulating fluidized bed; Standpipe bed height; Solids circulation rate; Multi-phase gas solids flow; Standpipe pressure profile ID FLOW AB Two models for a Circulating Fluidized Bed (CFB) standpipe were formulated, implemented and validated to estimate critical CFB operational parameters. The first model continuously estimates standpipe bed height using incremental pressure measurements within the standpipe. The second model estimates variations in the void fraction along the standpipe using the Ergun equation in conjunction with the overall pressure drop across the bed, solids circulation rate and the standpipe aeration flows introduced at different locations of the pipe. The importance of different standpipe parameters obtained from these models is discussed in terms of successful operation of the overall CFB system. Finally, the applications of these models are shown in improving the solids circulation rate measurement and in calculating riser inventory. Published by Elsevier B.V. C1 [Ludlow, J.

Reddy Hays, Roy Knowlton, Ted TI High speed imaging of particle flow fields in CFB risers SO POWDER TECHNOLOGY LA English DT Article DE High speed imaging; Fluidization; Circulating fluidized beds; Particle tracking ID CIRCULATING FLUIDIZED-BEDS; GRANULAR TEMPERATURE; SOLIDS; TURBULENT; WALL AB Particle flows of high particle concentration are important in many fields, including chemical processing, pharmaceutical processing, energy conversion and powder transport. Circulating fluidized beds (CFB) are widely employed in industry because they enhance reaction rates and heat transfer through rapid mixing of particles at high particle concentrations and high particle flow rates. However, despite decades of research and industrial application, the real time behavior of particle flow fields in CFB's is still not well understood. One of the reasons is that experimental data is difficult to acquire in such harsh, opaque environments. In this study, a new high speed particle imaging velocimetry (high speed PIV) technology, developed by the USDOE National Energy Technology Laboratory (NETL), is applied to observe and measure the real time behavior of individual particle motion inside the risers of CFB's. High speed PIV data acquired in three pilot scale CFB units at two laboratories: two CFB's with 0.305 m diameter risers and one CFB with a 0.2 m diameter riser. The high speed PIV system records high speed videos of particle motion with excellent spatial and temporal clarity. The high speed videos are analyzed to measure the concentration and the two-dimensional motion (velocity and trajectory) of individual particles. Data sample rates for velocity vectors are in the range of 0.1 to 3 million vectors per second thereby providing full resolution of the temporal domain of particle velocity. To see and measure particle motion inside the CFB risers at high particle concentrations, a custom borescope was inserted into the risers. The CFB risers were operated over a wide range of industrially relevant conditions: superficial gas velocities from 6.5 to 18.3 m/s with solid fluxes from 20 to 400 kg/m(2)/s. The particles used in the CFBs included fluid cracking catalyst (FCC) with a mean diameter of 70 mu m, high density polyethylene (HDPE) with a mean diameter of 750 mu m, and glass beads with mean diameters of 170 and 650 mu m. High speed videos and high speed PIV data enabled careful study of the real time behavior of gas-particle flow fields in CFB risers. In all of the CFBs of this study, one or more "jets" of high speed gas were observed at any time in the CFB risers. The jets move around the riser and appear to wander from one location against the riser wall to another. The jets have width range of 1/10 to 1/2 of the riser diameter. When a jet moves away from an area, the void is immediately filled with large clusters of particles. The clusters have sizes up to several riser diameters and contain significant percentages of the total particle flow. Clusters reduce mixing and interaction of particles with the transport gas, and therefore may inhibit reaction rates. Shearing of the clusters by high speed jets gives rise to cluster shapes that are either undulating or in the form of long, thin vertical strands which are often called streamers. The well known core-annulus concentration profile does not exist in real time, but rather is a long time averaged phenomenon. The data and insight from this work should be valuable for design and operation of risers, and for development of computational fluid dynamic (CFD) models of riser flow fields.

One of these simplifications was the use of a simplistic mass transfer correlation for the faster reactions and omission of mass transfer effects completely on the moderate speed and slow speed reactions such as those in a fluidized bed gasifier. Another problem that has propagated is that the mass transfer correlation used in the codes is not universal and is being used far from its developed bubbling fluidized bed regime when applied to circulating fluidized bed (CFB) riser reactors. These problems are true for the major CFD codes. To alleviate this problem, a mechanistic based mass transfer coefficient algorithm has been developed based upon an earlier work by Breault et al. [1-3]. This fundamental approach uses the local hydrodynamics to predict a local, time varying mass transfer coefficient. The predicted mass transfer coefficients and the corresponding Sherwood numbers agree well with literature data and are typically about an order of magnitude lower than the correlation noted above. The incorporation of the new mass transfer model gives the expected behavior for all the gasification reactions evaluated in the paper. At the expected and typical design values for the solid flow rate in a CFB riser gasifier an ANOVA analysis has shown the predictions from the new code to be significantly different from the original code predictions. The new algorithm should be used such that the conversions are not over predicted. Additionally, its behaviors with changes in solid flow rate are consistent with the changes in the hydrodynamics.

The reactor is a fluidized bed design based on a silica-supported amine sorbent CFD models using both Eulerian-Eulerian and Eulerian-Lagrangian multi-phase modeling methods are developed to investigate the hydrodynamics and adsorption of carbon dioxide in the reactor. Models developed in both FLUENT (R) and BARRACUDA are presented to explore the strengths and weaknesses of state of the art CFD codes for modeling multi-phase carbon capture reactors. The results of the simulations show that the FLUENT (R) Eulerian-Lagrangian simulations (DDPM) are unstable for the given reactor design; while the BARRACUDA Eulerian-Lagrangian model is able to simulate the system given appropriate simplifying assumptions. FLUENT (R) Eulerian-Eulerian simulations also provide a stable solution for the carbon capture reactor given the appropriate simplifying assumptions. (C) 2013 Elsevier B.V. All rights reserved.

TI Characterizing variability and reducing uncertainty in estimates of solar land use energy intensity SO RENEWABLE & SUSTAINABLE ENERGY REVIEWS LA English DT Review DE Land occupation; Photovoltaics; Concentrating solar power; Energy intensity; Electricity; Renewable ID ELECTRICITY-GENERATION; ENVIRONMENTAL IMPACTS; GEOTHERMAL-ENERGY; TECHNOLOGIES; ETHANOL; SYSTEMS AB Estimates of the amount of land used for a defined amount of utility-scale electricity generation in the solar power industry, referred to here as solar land use energy intensity (LUEI), are important to decision makers for evaluating the environmental impact of energy technology choices. However, these estimates for solar LUEI are calculated using three difficult-to-compare metrics and vary by as much as 4 orders of magnitude (0.042-64 m(2)/MWh) across the available literature. This study reduces, characterizes, and explicates the uncertainty in these values for photovoltaic (PV) and concentrated solar power (CSP) technologies through a harmonization process. In this harmonization process, a common metric is identified and data existing in other forms are converted to the metric, where possible; standard algorithms for calculating solar LUEI are developed; gaps and deficiencies in the literature calculations are identified and remedied; and differences among the resulting estimates are characterized and analyzed. The resulting range of harmonized solar LUEI estimates is reduced to 2 orders of magnitude [5-55 (m(2)y)/MWh]. Due to variables such as technology and location, there is a significant amount of irreducible variability in general solar LUEI estimates. However, this variability does not necessarily represent uncertainty, as most of it can be explained by choices in calculation input parameters. This study finds that key solar technology- and location-dependent parameters such as insolation, packing factor, system efficiency, and capacity factor all vary widely across studies, and thus all share in the overall variability of solar LUEI. Only land use at the site of solar electricity generation facilities is considered because lifecycle land use beyond the site (for manufacturing, disposal, etc.) is not widely accounted for in the existing literature. This study provides a basis for moving forward with standardized and comparable solar land use studies and for filling gaps in lifecycle solar LUEI. (C) 2013 Elsevier Ltd. All rights reserved.

Since laboratory measurements of D are representative of a very small volume, upscaling is necessary in order to incorporate these data in large-scale numerical models of diffusive transport. In this work we address the problem of the estimating the equivalent diffusion coefficient (D (eq) ), in terms of total diffusive flux, in a three-dimensional domain characterized by a heterogeneous and anisotropic spatial distribution of D. D (eq) was estimated from the results of steady-state diffusive transport simulations through several realizations of the D field. The ensemble averages of D (eq) from fields with different degrees of heterogeneity and anisotropy were then compared with estimates from analytical upscaling expressions based on stochastic as well as power-averaging approaches. These expressions are largely based on similar expressions developed for calculating the effective hydraulic conductivity in heterogeneous and anisotropic domains. Comparisons showed that stochastic expressions provide accurate estimates of D (eq) only for fields characterized by low heterogeneity. Within the range of heterogeneity and anisotropy considered, our results showed that a power-averaging expression is very accurate in predicting D (eq) especially when the parameter p (i) is estimated through fitting of the numerical results. Nonetheless, the relationship between this parameter and the anisotropy ratio is linear.

This article presented a reduced implicit finite difference scheme that based on proper orthogonal decomposition (POD) for two-dimensional transient mass transport in heterogeneous media. The reduction of the original full model was achieved by projecting the high-dimension full model to a low-dimension space created by POD bases, and the bases are derived from the snapshots generated from the model solutions of the forward simulations. The POD bases were extracted from the ensemble of snapshots by singular value decomposition. The dimension of the Jacobian matrix was then reduced after Galerkin projection. Thus, the reduced model can accurately reproduce and predict the original model's transport process with significantly decreased computational time. This scheme is practicable with easy implementation of the partial differential equations. The POD method is illustrated and validated through synthetic cases with various heterogeneous permeability field scenarios. The accuracy and efficiency of the reduced model are determined by the optimal selection of the snapshots and POD bases.

This paper presents an analytical solution for the steady Darcy flow of an incompressible fluid through a homogeneous, isotropic porous medium filling a channel bounded by symmetric wavy walls. This packed channel may represent an idealized packed fracture, a situation which is of interest as a potential pathway for the leakage of carbon dioxide from a geological sequestration site. The channel walls change from parallel planes, to small amplitude sine waves, to large amplitude nonsinusoidal waves as certain parameters are increased. The direction of gravity is arbitrary. A plot of piezometric head against distance in the direction of mean flow changes from a straight line for parallel planes to a series of steeply sloping sections in the reaches of small aperture alternating with nearly constant sections in the large aperture bulges. Expressions are given for the stream function, specific discharge, piezometric head, and pressure.

The current NHTSA analysis is the most thorough investigation of this issue to date. LBNL's assessment of the analysis indicates that the estimated effect of mass reduction on risk is smaller than in the previous studies, and statistically non-significant for all but the lightest cars. The effects three recent trends in vehicle designs and technologies have on societal fatality risk per VMT are estimated, and whether these changes might affect the relationship between vehicle mass and fatality risk in the future. Side airbags are found to reduce fatality risk in cars, but not necessarily light trucks or CUVs/minivans, struck in the side by another light-duty vehicle; reducing the number of fatalities in cars struck in the side is predicted to reduce the estimated detrimental effect of footprint reduction, but increase the detrimental effect of mass reduction, in cars on societal fatality risk. Better alignment of light truck bumpers with those of other vehicles appears to result in a statistically significant reduction in risk imposed on car occupants; however, reducing this type of fatality will likely have little impact on the estimated effect of mass or footprint reduction on risk. Finally, shifting light truck drivers into safer, car-based vehicles, such as sedans, CUVs, and minivans, would result in larger reductions in societal fatalities than expected from even substantial reductions in the masses of light trucks. A strategy of shifting drivers from truck-based to car-based vehicles would reduce fuel use and greenhouse gas emissions, while improving societal safety. (C) 2013 Elsevier Ltd. All rights reserved.

TI Simulation of neutron radiograph images at the Neutron Radiography Reactor SO ANNALS OF NUCLEAR ENERGY LA English DT Article DE Characteristic curve; Neutron radiography; Transfer method radiography; Image simulation AB The ability to accurately simulate potential radiographic images produced by a radiographic facility can improve the facility's ability to design experiments and evaluate images. The image simulation methods detailed in this paper predict the radiographic image of an object based on the foil reaction rate data obtained by placing a model of the object in front of the image plane in a Monte Carlo beamline model. The image simulation method utilizes a characteristic curve relating foil activity to optical density for the film and foil combination in use at the Neutron Radiography Reactor. The simulation validation compared a radiograph of a polyethylene step block to a simulated radiograph of the same step block. The simulation accurately predicts the optical density in each region of a radiograph of the step block. The simulated radiograph predicts the average optical density of the actual radiograph more accurately for the thinner steps, resulting in step averaged optical density differences between the actual and simulated images of -11.6% for the thinnest step versus a difference of -34.7% for the thickest step, possibly due to the greater accuracy of the higher optical density region of the characteristic curve. Applying the scanner calibration curve to the calculated optical density values decreases the difference between the actual radiograph pixel values and the simulated pixel values for each step except the thinnest step. The step averaged differences between the corrected and actual images increase from -11.6% to -17.0% for the thinnest step and decrease from -34.7% to +7.7% for the thickest step after the calibration curve is applied.

The Al alloy in the ethanol and its solutions exhibited a capacitive loop in the measured Nyquist EIS spectra at high frequencies, which can be attributed to the ethanol's dielectric response. Addition of 10 vol.% acetic acid increased the ethanol corrosivity more significantly than the same amount of water addition. The Al-Si-Cu-Mg precipitated zones in the alloy were susceptible to corrosion attack due to the micro-galvanic effect by the Cu-containing precipitates. (C) 2013 Elsevier Ltd. All rights reserved.

TI Energy use and CO2 emissions of China's industrial sector from a global perspective SO ENERGY POLICY LA English DT Article DE Industry energy; CO2 emission; Saturation effect ID STRATEGIES; FRAMEWORK; DEMAND AB The industrial sector has accounted for more than 50% of China's final energy consumption in the past 30 years. Understanding the future emissions and emissions mitigation opportunities depends on proper characterization of the present-day industrial energy use, as well as industrial demand drivers and technological opportunities in the future. Traditionally, however, integrated assessment research has handled the industrial sector of China in a highly aggregate form. In this study, we develop a technologically detailed, service-oriented representation of 11 industrial subsectors in China, and analyze a suite of scenarios of future industrial demand growth. We find that, due to anticipated saturation of China's per-capita demands of basic industrial goods, industrial energy demand and CO2 emissions approach a plateau between 2030 and 2040, then decrease gradually. Still, without emissions mitigation policies, the industrial sector remains heavily reliant on coal, and therefore emissions-intensive. With carbon prices, we observe some degree of industrial sector electrification, deployment of CCS at large industrial point sources of CO2 emissions at low carbon prices, an increase in the share of CHP systems at industrial facilities. These technological responses amount to reductions of industrial emissions (including indirect emission from electricity) are of 24% in 2050 and 66% in 2095. (C) 2013 Elsevier Ltd.

TI Systematic variations of argon diffusion in feldspars and implications for thermochronometry SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID AR-40/AR-39 K-FELDSPAR; THERMAL-EXPANSION; PHASE-TRANSITION; ALKALI FELDSPARS; PLAGIOCLASE FELDSPARS; HIGH ALBITE; X-RAY; DISPLACIVE TRANSFORMATION; INTERMEDIATE PLAGIOCLASE; CALCIC PLAGIOCLASE AB Coupled information about the time-dependent production and temperature-dependent diffusion of radiogenic argon in feldspars can be used to constrain the thermal evolution attending a host of Earth and planetary processes. To better assess the accuracy of thermal models, an understanding of the mechanisms and pathways by which argon diffuses in feldspars is desirable. Here we present step-heating Ar diffusion experiments conducted on feldspars with diverse compositions, structural states, and microstructural characteristics. The experiments reveal systematic variations in diffusive behavior that appear closely related to these variables, with apparent closure temperatures for 0.1-1 mm grains of similar to 200-400 degrees C (assuming a 10 degrees C/Ma cooling rate). Given such variability, there is no broadly applicable set of diffusion parameters that can be utilized in feldspar thermal modeling; sample-specific data are required. Diffusion experiments conducted on oriented cleavage flakes do not reveal directionally-dependent diffusive anisotropy to within the resolution limits of our approach (approximately a factor of 2). Additional experiments aimed at constraining the physical significance of the diffusion domain are presented and indicate that unaltered feldspar crystals with or without coherent exsolution lamellae diffuse at the grain-scale, whereas feldspars containing hydrothermal alteration and/or incoherent sub-grain intergrowths do not. Arrhenius plots for argon diffusion in plagioclase and alkali feldspars appear to reflect a confluence of intrinsic diffusion kinetics and structural transitions that occur during incremental heating experiments. These structural transitions, along with sub-grain domain size variations, cause deviations from linearity (i.e., upward and downward curvature) on Arrhenius plots. An atomistic model for Arrhenius behavior is proposed that incorporates the variable lattice deformations of different feldspars in response to heating and compression. The resulting implications for accurately extrapolating laboratory-derived diffusion parameters to natural settings and over geologic time are discussed. We find that considerable inaccuracies may exist in published thermal histories obtained using multiple diffusion domain (MDD) models fit to Arrhenius plots for exsolved alkali feldspar, where the inferred Ar partial retention zones may be spuriously hot.

The assemblies of pipes that constitute the ground heat exchangers occupy volumes that are shaped as parallelepipeds, the short dimension of which is vertical. Viewed from above, the assemblies occupy rectangular areas with variable shapes. Two area sizes are considered: few large areas surrounded by many smaller areas. The area shapes are viewed systematically such that the total heat transfer rate between ground and buried assemblies is maximum. For each shape of the large assembly, the best shape of each smaller assembly is the most slender that can be installed on its available territory. This feature of the neighborhood design does not change when the volume fraction occupied by all the assemblies increases. (C) 2013 Elsevier Ltd. All rights reserved.

Within the context of non-smooth dynamics, we introduce an extension to the classical set-valued model for frictional contacts between rigid bodies, allowing contacts to experience local compliance, viscosity, and plasticization. Different types of yield surfaces can be defined for various types of contact, a versatile approach that contains the classic dry Coulomb friction as a special case. The resulting problem is a differential variational inequality that can be solved, at each integration time step, as a variational inequality over a convex set. (C) 2013 Elsevier Ltd.

Specimens were produced such that outer layers of FeCrAl ferritic alloy and Type 310 austenitic stainless steel were incorporated on the surface of zirconium metal slugs. The specimens were exposed to high-temperature 0.34 MPa steam at 1200 and 1300 degrees C. The primary degradation mechanism for the protective layer was interdiffusion with the zirconium, as opposed to high-temperature oxidation in steam. The FeCrAl layer experienced less degradation and protected the zirconium at 1300 degrees C for 8 h. Constituents of the Fe-base alloys rapidly diffused into the zirconium and resulted in the formation of various intermetallic layers at the interface and precipitates inside the bulk zirconium. The nature of this interaction for FeCrAl and 310SS has been characterized by use of microscopic techniques as well as computational thermodynamics. Finally, a reactor physics discussion on the applicability of these protective layers in light-water-reactor nuclear fuel structures is offered. Published by Elsevier B.V.

TI Effect of double ion implantation and irradiation by Ar and He ions on nano-indentation hardness of metallic alloys SO JOURNAL OF NUCLEAR MATERIALS LA English DT Article ID NANOINDENTATION AB In this study, the authors have investigated the combined effect of a double layer of implantation on four different metallic alloys, ODS steel MA957, Zircaloy-4, Ti-6Al-4V titanium alloy and stainless steel 316, by ions of two different species - He and Ar - on the hardening of the surface as measured by nanoindentation. The data was collected for a large number of indentations using the Continuous Stiffness Method or "CSM" mode, applying the indents on the implanted surface. Careful analysis of the data in the present investigations show that the relative hardening due to individual implantation layers can be used to obtain an estimate of the relative hardening effect of a combination of two separate implanted layers of two different species. This combined hardness was found to lie between the square root of the sum of the squares of individual hardening effects, (Delta H-A(2) + Delta H-B(2))(0.5) as the lower limit and the sum of the individual hardening effects, (Delta H-A + Delta H-B) as the upper limit, within errors, for all depths measured.

The alloy was prepared from copper and tin (10 mass%) powders. Pre-sintered ceramic consisting of cesium, strontium, barium and rubidium alumino-silicates was mixed with unalloyed bronze precursor powders and cold pressed to 300 x 10(3) kPa, then sintered at 600 degrees C and 800 degrees C under hydrogen. Cermets were also prepared that incorporated molybdenum, which has a limited solubility in glass, under similar conditions. The cermet thermal conductivities were seven times that of the ceramic alone. These improved thermal properties can reduce thermal gradients within the waste forms thus lowering internal temperature gradients and thermal stresses, allowing for larger waste forms and higher waste loadings. These benefits can reduce the total number of waste packages necessary to immobilize a given amount of high level waste and immobilize troublesome elements. Published by Elsevier B.V.

TI Variability in EBSD statistics for textured zirconium SO MATERIALS SCIENCE AND ENGINEERING A-STRUCTURAL MATERIALS PROPERTIES MICROSTRUCTURE AND PROCESSING LA English DT Article DE Electron backscatter diffraction (EBSD); Twinning; Zirconium ID ELECTRON BACKSCATTER DIFFRACTION; TWIN STATISTICS; MAGNESIUM AB Zirconium is an important structural material, and, as with other hexagonal close-packed (HCP) metals, the mechanical properties depend on both slip and twinning. Electron backscatter diffraction (EBSD) from two-dimensional (2D) metallographic sections has previously been used to identify and quantify deformation twinning to support development of physically based plasticity models for HCP metals. However, the stereological assumptions used to generate twin statistics from a single 2D section have not been fully validated against potential sources of measurement artifacts or biases potentially arising from the strong initial material textures and crystallographic nature of twinning. This work addresses these concerns by comparing results from three orthogonal directions in a deformed sample. Few differences are observed in the twin statistics based on viewing direction. Statistical variability of microstructures is a bigger factor in the comparison of twin statistics than viewing direction. {10 (1) over bar2} twinning does not occur homogeneously throughout the microstructure during a compression test.

TI A numerical investigation of the sCO(2) recompression cycle off-design behaviour, coupled to a sodium cooled fast reactor, for seasonal variation in the heat sink temperature SO NUCLEAR ENGINEERING AND DESIGN LA English DT Article ID DIOXIDE BRAYTON CYCLE; EFFICIENCY AB Supercritical CO2 cycles are particularly attractive for Generation IV Sodium-Cooled Fast Reactors (SFRs) as they can be simple and compact, but still offer steam-cycle equivalent efficiency while also removing potential for Na/H2O reactions. However, CO2 thermophysical properties are very sensitive close to the critical point which raises, in particular, questions about the compressor and so cycle off-design behaviour when subject to inevitable temperature increases that result from seasonal variations in the heat sink temperature. This publication reports the numerical investigation of such an issue that has been performed using the Plant Dynamics Code (ANL, USA), the cycle being optimised for the next French SFR, ASTRID (1500 MWth), as a test-case. On design, the net plant efficiency is 42.2% for a high pressure (25 MPa) turbine with an inlet temperature of 515 degrees C and considering a cycle low temperature of 35 degrees C. The off-design cycle behaviour is studied based on preliminary designs for the main components and assuming the use of a fixed heat sink flow rate. First results obtained using a common fixed shaft speed for all turbomachines, without any other active control, show no stability issues and roughly constant density (and volumetric flow rate) at the main compressor inlet for the range of heat sink temperature considered (21-40 degrees C). This occurs because the new stationary states are found without requiring a significant shift of mass to the higher pressure level, meaning the compressor inlet pressure rises in concert with temperature. A significant fall in the loop thermal power and efficiency is observed however, which analysis reveals to be caused by a fall in pressure ratio that is an inevitable result of the non-ideal nature of sCO(2). Indeed the difference in the compressors off-design performance (the recompression cycle arrangement features 2 parallel compressors) is such that more mass-flow is attracted in the bypass line, which has a negative impact on cycle efficiency. A second series of results are taken for which the main compressor speed alone is controlled (between 50 and 56 rev/s) and successfully maintains a constant thermal power across the sodium-CO2 heat exchanger. The resulting higher pressure ratio (compared to the fixed speed results) and greater flow rate through the main compressor also lead to higher cycle efficiencies that are close to the optimum achievable for a given heat sink temperature. The series of tests reveals that to achieve a constant thermal power and high efficiency with the sCO(2) cycle at elevated heat sink temperatures, a degree-of-freedom in the compressor performance is necessary.

In prismatic reactors, hexagonal graphite bricks are used as reflectors and fuel bricks. In the reactor environment, graphite bricks experience high temperature and neutron dose. This leads to dimensional changes (swelling and or shrinkage) of these bricks. Irradiation dimensional changes may affect the structural integrity of the individual bricks as well as of the overall core. The present paper presents a generic procedure for stress analysis of prismatic core graphite components using graphite reflector as an example. The procedure is demonstrated through commercially available ABAQUS finite element software using the option of user material subroutine (UMAT). This paper considers General Atomics Gas Turbine-Modular Helium Reactor (GT-MHR) as a bench mark design to perform the time integrated stress analysis of a typical reflector brick considering realistic geometry, flux distribution and realistic irradiation material properties of transversely isotropic H-451 grade graphite.

Energy spectra produced under irradiation by a range of gamma-ray and neutron sources were collected with CLYC mounted to several avalanche photodiodes, PIN photodiodes, and silicon photomultipliers. The performance for both gamma rays and neutrons was compared to that obtained by coupling CLYC to PMTs. None of the silicon devices evaluated provide comparable performance to that of a PMT with CLYC. This is attributed to the photon-detection efficiency of the silicon detectors over the wavelength range of CLYC emissions, as well as the noise characteristics of the devices. (c) 2013 Elsevier B.V.

The mode of action underlying these effects is unclear. We used global gene expression analysis to identify candidate genes and signaling pathways that mediate BPA's developmental toxicity in zebrafish. Exposure concentrations were selected and anchored to the positive control, 17 beta-estradiol (E2), based on previously determined behavioral or teratogenic phenotypes. Functional analysis of differentially expressed genes revealed distinct expression profiles at 24 h post fertilization for 0.1 mu M versus 80 mu M BPA and 0.1 mu M versus 15 mu M E2 exposure, identification of prothrombin activation as a top canonical pathway impacted by both 0.1 mu M BPA and 0.1 mu M E2 exposure, and suppressed expression of several genes involved in nervous system development and function following 0.1 mu M BPA exposure.

At each step we find several pathways that could lead to further reductions in manufacturing costs. After aggregating the performance and cost considerations for a series of known technical improvement opportunities, we project a pathway for commercial-production c-Si modules to have typical sunlight power conversion efficiencies of 19-23%, and we calculate that they might be sustainably sold at ex-factory gate prices of $0.60-$0.70 per peak Watt (DC power, current U.S. dollars). This may not be the lower bound to the cost curve for c-Si, however, because the roadmap described in this paper is constrained by the boundary conditions set by the wire sawing of wafers and their incorporation into manufacturing equipment that is currently being developed for commercial-scale production. Within these boundary conditions, we find that the benefit of reducing the wafer thickness from today's standard 180 mu m to the handling limit of 80 mu m could be around $0.05 per peak Watt (W-p), when the calculation is run at minimum sustainable polysilicon prices (which we calculate to be around $23/kg). At that minimum sustainable polysilicon price, we also calculate that the benefit of completely eliminating or completely recycling kerf loss could be up to $0.08/W-p. These downward adjustments to the long run wafer price are used within the cost projections for three advanced cell architectures beyond today's standard c-Si solar cell. Presumably, the higher efficiency cells that are profiled must be built upon a foundation of higher quality starting wafers. The prevailing conventional wisdom is that this should add cost at the ingot and wafering step either due to lower production yields when having to sell wafers that are doped with an alternative element other than the standard choice of boron, or in additional capital equipment costs associated with removing problematic boron-oxygen pairs. However, from our survey it appears that there does not necessarily need to be an assumption of a higher wafer price if cell manufacturers should wish to use n-type wafers derived from the phosphorus dopant. And as for making p-type wafers with the traditional boron dopant, the potential price premium for higher lifetimes via the magnetic Czochralski approach is calculated to be very small, and can ostensibly be offset by the higher expected cell efficiencies that would result from using the higher quality wafers. With this final consideration, the projected minimum sustainable price requirements for three advanced c-Si solar cells are incorporated into a final bill of materials for a polysilicon-to-module manufacturing facility located within the United States.

Analyzed GaAs p-i-n structures comprise five layers of either GaSb quantum dot (QD), InGaAs quantum well (QW) or GaSb/InGaAs QDW layers in the I-region. It is found that the QDW solar cells outperform the QW and QD solar cells beyond GaAs band edge. In QDW solar cells an increase in efficiency is observed over QD solar cells due to additional QW absorption. An analysis of bulk response degradation in QDW solar cell is also presented. Improved photoresponse in QDW solar cells over QW and QD solar cells proves the potential for QDW hybrid structures in achieving high efficiency intermediate band solar cells. (C) 2013 Elsevier B.V.

METHODS: We searched PubMed/MEDLINE, Embase, and Scopus for original data about racial/ethnic disparities in the diagnosis, prevalence, treatment, or clinical course of food allergy or sensitization, with a particular focus on black (African American) race. Articles were analyzed by study methodology, racial/ethnic composition, food allergy definition, outcomes, summary statistic used, and covariate adjustment. RESULTS: Twenty of 645 identified articles met inclusion criteria. The studies used multiple differing criteria to define food allergy, including self-report, sensitization assessed by serum food-specific IgE to selected foods without corroborating history, discharge codes, clinic chart review, and event-reporting databases. None used oral food challenge. In 12 studies, black persons (primarily children) had significantly increased adjusted odds of food sensitization or significantly higher proportion or odds of food allergy by self-report, discharge codes, or clinic-based chart review than white children. Major differences in study methodology and reporting precluded calculation of a pooled estimate of effect. CONCLUSION: Sparse and methodologically limited data exist about racial/ethnic disparity in food allergy in the United States. Available data lack a common definition for food allergy and use indirect measures of allergy, not food challenge. Although data suggest an increased risk of food sensitization, self-reported allergy, or clinic-based diagnosis of food allergy among black children, no definitive racial/ethnic disparity could be found among currently available studies.

These materials can also possess electronic phase separation in which regions of vastly different resistive and magnetic behavior can coexist within a single crystal alloy material. By reducing the scale of these materials to length scales at and below the inherent size of the electronic domains, novel behaviors can be exposed. Because of this and the fact that spin-charge-lattice-orbital order parameters each involve correlation lengths, spatially reducing these materials for transport measurements is a critical step in understanding the fundamental physics that drives complex behaviors. These materials also offer great potential to become the next generation of electronic devices (1-3). Thus, the fabrication of low dimensional nano-or micro-structures is extremely important to achieve new functionality. This involves multiple controllable processes from high quality thin film growth to accurate electronic property characterization. Here, we present fabrication protocols of high quality microstructures for complex oxide manganite devices. Detailed descriptions and required equipment of thin film growth, photo-lithography, and wire-bonding are presented.

For these molecules that conduct through the highest occupied molecular orbital, junctions formed with Au electrodes are more conductive than those formed with Ag electrodes, consistent with the lower work function for Ag. The measured conductance decays exponentially with molecular backbone length with a decay constant that is essentially the same for Ag and Au electrodes. However, the formation and evolution of molecular junctions upon elongation are very different for these two metals. Specifically, junctions formed with Ag electrodes sustain significantly longer elongation when compared with Au due to a difference in the initial gap opened up when the metal point-contact is broken. Using this observation and density functional theory calculations of junction structure and conductance we explain the trends observed in the single molecule junction conductance. Our work thus opens a new path to the conductance measurements of a single molecule junction in Ag electrodes.

They are integral to the operation of industrial facilities by providing the essential conversion of energy into useful work, energized fluids or heat required for production processes. Improving the efficiency of industrial energy systems does not require major investment in new processes or equipment. Barriers to systems optimization are often behavioral rather than financial, with system inefficiencies frequently attributable to lack of knowledge. Measurement of the efficiency of motor and steam systems is not done and projects capable of improving systems efficiency do not attract the attention of company managers. In developed countries, where energy efficiency is now an important component of climate policy, measures capable of driving systems level improvements, have been introduced, but, to date, their impacts have been limited. The challenge for policy makers worldwide is to bring about a lasting change in industrial management behavior that recognizes the benefits of systems optimization. The International Standards Organization 50001 Energy Management Standard will afford industrial managers with an opportunity to address systems optimization within the organizing framework of an energy management system standard, thus supporting continuous improvement in energy performance.

For this, achieving the highest possible spatial resolution is advantageous, in order to capture the intricate details of complex microstructures. Spectral methods, as an efficient alternative to the widely used finite element method (FEM), have been established during the last decade and their applicability to the case of polycrystalline materials has already been demonstrated. However, until now, the existing implementations were limited to infinitesimal strain and phenomenological crystal elasto-viscoplasticity. This work presents the extension of the existing spectral formulation for polycrystals to the case of finite strains, not limited to a particular constitutive law, by considering a general material model implementation. By interfacing the exact same material model to both, the new spectral implementation as well as a FEM-based solver, a direct comparison of both numerical strategies is possible. Carrying out this comparison, and using a phenomenological constitutive law as example, we demonstrate that the spectral method solution converges much faster with mesh/grid resolution, fulfills stress equilibrium and strain compatibility much better, and is able to solve the micromechanical problem for, e.g., a 256(3) grid in comparable times as required by a 64(3) mesh of linear finite elements.

Since these effects are related to the rearrangement of the dislocation structure induced during previous loading, here we propose a crystallographically-based dislocation hardening model for capturing such behavior. The model is implemented in the polycrystal code VPSC and is applied to simulate strain path changes in low carbon steel. The path changes consist of tension followed by shear at different angles with respect to the preload direction, and forward simple shear followed by reverse shear. The results are compared to experimental data and highlight the role that directional dislocation structures induced during preload play during the reload stage. (C) 2012 Elsevier Ltd.

The framework is an extension of the modified Newton's method with nonlinear Krylov accelerator developed by Carlson and Miller [1], Miller [2] and Scott and Fenves [3]. Our extensions include the retention of subspace information over multiple timesteps, and a special correction at the end of a timestep that allows for corrections to be accepted with verified low residual with as little as a single residual evaluation per timestep on average. In the case of a single residual evaluation per timestep, the method has zero additional computational cost compared to uncoupled or unidirectionally coupled simulations. We expect these enhancements to be generally applicable to other multiscale coupling applications where timestepping occurs. In addition we have developed a "pressure-drop" residual which allows for stable coupling of flows between a 3D incompressible CFD application and another (lower-dimensional) fluid system. We expect this residual to also be useful for coupling non-respiratory incompressible fluid applications, such as multiscale simulations involving blood flow. The lower-dimensional models that are considered in this study are sets of simple ordinary differential equations (ODEs) representing the compliant mechanics of symmetric human pulmonary airway trees. To validate the method, we compare the predictions of hybrid CFD-ODE models against an ODE-only model of pulmonary airflow in an idealized geometry. Subsequently, we couple multiple sets of ODEs describing the distal lung to an imaging-based human lung geometry. Boundary conditions in these models consist of atmospheric pressure at the mouth and intrapleural pressure applied to the multiple sets of ODEs. In both the simplified geometry and in the imaging-based geometry, the performance of the method was comparable to that of monolithic schemes, in most cases requiring only a single CFD evaluation per time step. Thus, this new accelerator allows us to begin combining pulmonary CFD models with lower-dimensional models of pulmonary mechanics with little computational overhead. Moreover, because the CFD and lower-dimensional models are totally separate, this framework affords great flexibility in terms of the type and breadth of the adopted lower-dimensional model, allowing the biomedical researcher to appropriately focus on model design.

Electropolishing below the quadrijunction revealed a 3-D microstructure characterized by a rapidly shrinking grain with a faceted boundary indicating a significant anisotropy of energy and/or mobility. This unusual occurrence is described in detail in the expectation that a reasonable model for this observation might be found. Published by Elsevier Ltd. on behalf of Acta Materialia Inc.

In this direction < c + a > slip is the preferred slip mode. We observed the operation of a < c + a > dislocation source while simultaneously measuring the mechanical response.

We show theoretical spectra which consider the relationship between rotational and translational transitions in the highly anisotropic adsorption environment, proving that different rotational excitations contain different amount of recoil broadening and motivating a new analysis method which considers both types of transitions at once. Spectra for most of the samples, including two activated carbons, are very similar to one another, supporting models of nanoporous carbons which are quite similar on the sub-nanometer scale. The exception is the low-energy side of the rotational peak, indicating important differences in the initial distribution of motion. We also find more subtle differences in the spectra which may be linked to differences in sample heterogeneity and surface rugosity. One sample does have a very different spectrum, which is not explained by standard models of this system. We also observe a significantly reduced effective mass in the spectrum of recoil transitions and evidence of coupling of rotational and translational motion resulting from periodic variations in orientation of the rotational states.

The data, generated elsewhere, measured the tensile and four-point-flexure room-temperature rupture strength of specimens cut from a single extruded graphite log. Strength variation versus specimen location, size, and orientation relative to the parent body were compared. In our study, data were progressively and extensively pooled into larger data sets to discriminate overall trends from local variations and investigate the strength distribution. Issues regarding size effect, Weibull parameter consistency, and nonlinear stress-strain response were investigated using the Ceramics Analysis and Reliability Evaluation of Structures Life Prediction Program (CARES/Life) and WeibPar codes. Overall, the Weibull distribution described the behavior of the pooled data very well. The Weibull modulus was shown to be clearly consistent between different tensile specimen sizes and orientations. However, the issue regarding the smaller-than-expected size effect remained. This exercise illustrated that a conservative approach using a two-parameter Weibull distribution is best for designing graphite components with low probability of failure for the in-core structures in the proposed Generation IV high-temperature gas-cooled nuclear reactors. This exercise also demonstrated the continuing need to better understand the mechanisms driving stochastic strength response. Published by Elsevier Ltd.

This study focused on reducing HC and CO emissions in the exhaust emissions by the bioethanol blending of diesel. A narrow angle injector with an injection angle of 70 degrees was used and compared with a conventional angle injector having a 156 degrees injection angle. The bioethanol was blended with the conventional diesel up to 30% with 5% biodiesel. Experiments revealed that, in a narrow angle injector, the premixed combustion duration increased with bioethanol contents unlike the similar value of conventional injector. The premixed combustion phasing decreased with the increase of bioethanol in both injectors. The variation in the peak combustion pressure of the narrow angle injector was smaller than that of a conventional injector. In addition, the narrow angle injector induced a higher indicated mean effective pressure (IMEP) and a shorter ignition delay compared to the conventional injector. In terms of exhaust emissions characteristics, the low and stable ISHC and ISCO emissions can be achieved through the application of narrow angle injector to the diesel-bioethanol blends combustion. By the early injection combustion strategy, ISHC and ISCO emissions are significantly reduced. (C) 2013 Elsevier Ltd. All rights reserved.

Ten-cycle CLC tests were conducted with Fe-Cu oxygen carriers in an atmospheric thermogravimetric analyzer utilizing simulated synthesis gas derived from the steam gasification of Polish Janina coal and Illinois #6 coal as fuel. The effect of temperature on reaction rates, chemical stability, and oxygen transport capacity were determined. Fractional reduction, fractional oxidation, and global rates of reactions were calculated from the thermogravimetric analysis (TGA) data. The supports greatly affected reaction performance. Data showed that reaction rates and oxygen capacities were stable during the 10-cycle TGA tests for most Fe-Cu/support oxygen carriers. Bimetallic Fe-Cu/support oxygen carriers showed higher reduction rates than Fe-support oxygen carriers. The carriers containing higher Cu content showed better stabilities and better reduction rates. An increase in temperature from 800 degrees C to 900 degrees C did not have a significant effect on either the oxygen capacity or the reduction rates with synthesis gas derived from Janina coal. Oxidation reaction was significantly faster than reduction reaction for all supported Fe-Cu oxygen carriers. Carriers with higher Cu content had lower oxidation rates. Ten-cycle TGA data indicated that these oxygen carriers had stable performances at 800-900 degrees C and might be successfully used up to 900 degrees C for coal CLC reaction in the presence of steam.

In order to reliably predict mechanical and thermodynamic properties of Mo-based alloys, the Mo-Si-B model system is studied using first-principles density functional theory methods. Specifically, five intermetallic compounds MoSi2, Mo5Si3, Mo3Si, Mo5SiB2 and MO2B are chosen, and their equilibrium lattice parameters, elastic properties, phonon spectra, and thermodynamic properties are calculated and compared, most of them for the first time. It is shown that for the calculated properties where the measured data are available, the predicted results are in very good agreement with available experiments, thus validate our computational methodologies. Our comprehensive and systematic calculations reveal many interesting and previously unknown features in the mechanical and vibrational properties of these alloys in relation to their structure and composition. It is shown that boron in the Mo-Si-B system enhances elastic and bulk properties without compromising ductility. MoSi2, which has the largest Si concentration, also has the largest elastic anisotropy compared with the other four crystals. (c) 2013 Elsevier Ltd. All rights reserved.

Previous model studies indicate that injectivity can be impaired by salt precipitation near the injection well. These results are largely determined by the relationships between permeability and salt precipitation. In this study, we develop a new relationship for permeability change owing to salt precipitation near a CO2 injection well. This relationship differs from previous relationships in that it considers the fact that the salt precipitation occurs only in pore space occupied by brine during the precipitation process, and in that it is based on well-established relative-permeability relationships for two-phase flow in porous media. Using this relationship, we can link permeability change to the effects of saturation in a CO2-brine system and the pore-size distribution of porous media. Its usefulness is demonstrated by the good agreement between predicted results and observations from a laboratory experiment. The developed methodology, in principle, can also be applied to other two-phase flow systems involving chemical-reaction-induced permeability changes. (c) 2013 Elsevier Ltd. All rights reserved.

Accurate modeling of subsurface geochemical processes related to geologic carbon sequestration requires experimentally derived data for mineral reactions. Most work in this area has focused on aqueous-dominated systems in which dissolved CO2 reacts to form crystalline carbonate minerals. Comparatively little laboratory research has been conducted on reactions occurring between minerals in the host rock and the wet supercritical fluid phase. We studied the carbonation of wollastonite [CaSiO3] exposed to variably hydrated supercritical CO2 (scCO(2)) at 50, 55 and 70 degrees C and 90, 120 and 160 bar. Reactions were followed by three novel in situ high pressure techniques, which demonstrated increased dissolved water concentrations in the scCO(2) resulted in increased wollastonite carbonation approaching similar to 50 wt.%. Overall, the X-ray diffraction and infrared and magic angle nuclear magnetic resonance spectroscopies experiments conducted in this study allow detailed examination of mechanisms impacting carbonation rates. These include the development of amorphous passivating layers, thin liquid water films, and amorphous hydrated carbonate phases. Collectively, these results emphasize the importance of understanding geochemical processes occurring in wet scCO(2) fluids. (c) 2013 Published by Elsevier B.V. C1 [Miller, Q. R.

Multiphonon relaxation of the primary emitting states in Tb3+ (D-5(3) and D-5(4)), Sm3+ ((4)G(5/2)), and Eu3+ (D-5(0)) was found to be negligible in the present host. The relaxation of Tb3+ (D-5(4)) and Eu3+ (D-5(0)) is dominated by radiative decay. For Tb3+ (D-5(3)) and Sm3+ ((4)G(5/2)) in contrast, radiative relaxation is in competition with several non-radiative cross-relaxation processes. This competition was found to be particularly pronounced for the D-5(3) excited state in Tb3+, where a 124-fold decrease of the (D-5(3)-> F-7(5))/(D-5(4)-> F-7(5)) emission intensity ratio and a similar to 10-fold shortening of the D-5(3) lifetime was observed upon increasing the Tb3+ concentration from 0.01% to 1%. The Tb3+ concentration dependence of D-5(3) also points to some degree of ion aggregation in the "as quenched" glasses. A Judd-Ofelt intensity analysis was performed for Sm3+ and used to estimate the relative magnitude of (4)G(5/2) cross-relaxation processes. Four cross-relaxation processes in particular were identified to account for 92% of the total (4)G(5/2) non-radiative decay, and a 11% quantum efficiency was estimated for the (4)G(5/2) excited state. Non-exponentiality in the D-5(0) decay of Eu3+ is evidence for several Eu3+ coordination environments in the glass host that manifest in different D-5(0) decay constants because of the hypersensitivity of the D-5(0)-> F-7(2) transition.

TI Assessment of the validity and intrusiveness of online-probe questions for situation awareness in a simulated air-traffic-management task with student air-traffic controllers SO SAFETY SCIENCE LA English DT Article DE Situation awareness measurement; Online probe technique; SPAM; Intrusiveness; Validity ID DYNAMIC-SYSTEMS; ERRORS AB Online-probe techniques for measuring situation awareness (SA) represent an alternative to offline-probe methods in which operators are queried about the situation during scenario freezes with displays blanked. Online-probe queries are administered while the task is ongoing and displays active. However, online-probes techniques have not been validated to the same extent as offline probes, and have been criticized because asking questions about the current or future situation while the task is active could change the operator's subsequent awareness of the situation. The present investigation examined the possibility of the intrusiveness of the online-probe technique to an operator's SA. Twelve student air-traffic controllers (ATCos) served as participants and managed traffic in six 30-min scenarios in which online probes were administered regularly. Off-nominal flight-plan deviations followed some probe queries. Three pre-event question types were administered prior to scheduled flight-plan deviations. These pre-event questions were either relevant to the deviating event and subsequent conflict, relevant to conflicts but not the deviating event, or unrelated to both conflicts and the deviating event. The type of pre-event question preceding a flight-plan deviation did not change the time to detect the deviating event nor the number of losses of separation (LOS) created by the deviation. Moreover, online probes were related to measures of sector safety. (C) 2012 Elsevier Ltd. All rights reserved. C1 [Bacon, L.

The calculations were made for the four final, or scattered, electron energies E' = 0.20, 0.42, 0.80, and 1.40, where E' is in units of Z(eff)(2) Ry with Z(eff) = Z - 2.5. In the present calculation, an improved "top-up" method, which employs relativistic plane waves, was used to obtain the high partial-wave contribution for each transition, in contrast to the partial-relativistic Coulomb-Bethe approximation used in previous work by Zhang and Sampson [H.L. Zhang and D.H. Sampson, At. Data Nucl. Data Tables 52 (1992) 143]. In that earlier work, collision strengths were also provided for Be-like ions, but for a more comprehensive data set consisting of all 45 Delta n = 0 transitions, six scattered energies, and the 85 ions with Z in the range 8 <= Z <= 92. The collision strengths covered in the present work should be more accurate than the corresponding data given by Zhang and Sampson [HI. Zhang and D.H. Sampson, At. Data Nucl.

It is used as reactivity unit referred to as "dollar". Usually, it is obtained by computer simulation due to the difficulty in measuring it experimentally. In 1965, Keepin proposed a method, widely used in the literature, for the calculation of the effective delayed neutron fraction beta(eff). This method requires calculation of the adjoint neutron flux as a weighting function of the phase space inner products and is easy to implement by deterministic codes. With Monte Carlo codes, the solution of the adjoint neutron transport equation is much more difficult because of the continuous-energy treatment of nuclear data. Consequently, alternative methods, which do not require the explicit calculation of the adjoint neutron flux, have been proposed. In 1997, Bretscher introduced the k-ratio method for calculating the effective delayed neutron fraction; this method is based on calculating the multiplication factor of a nuclear reactor core with and without the contribution of delayed neutrons. The multiplication factor set by the delayed neutrons (the delayed multiplication factor) is obtained as the difference between the total and the prompt multiplication factors. Using Monte Carlo calculation Bretscher evaluated the beta(eff) as the ratio between the delayed and total multiplication factors (therefore the method is often referred to as the k-ratio method). In the present work, the k-ratio method is applied by Monte Carlo (MCNPX) and deterministic (PARTISN) codes. In the latter case, the ENDF/B nuclear data library of the fuel isotopes (U-235 and U-238) has been processed by the NJOY code with and without the delayed neutron data to prepare multi-group WIMSD neutron libraries for the lattice physics code DRAGON, which. was used to generate the PARTISN macroscopic cross sections. In recent years Meulekamp and van der Marck in 2006 and Nauchi and Kameyama in 2005 proposed new methods for the effective delayed neutron fraction calculation with only one Monte Carlo computer simulation, compared with the k-ratio method which require two criticality calculations. In this paper, the Meulekamp/Marck and Nauchi/Kameyama methods are applied for the first time by the MCNPX computer code and the results obtained by all different methods are compared.

The formulation admits general potentials and meshes: uniform, exponential, or other defined by nodal distribution and derivative functions. For a given mesh type, convergence can be controlled systematically by increasing the number of grid points. Radial integrations are carried out using a combination of asymptotic forms, Runge-Kutta, and implicit Adams methods. Eigenfunctions are determined by a combination of bisection and perturbation methods for robustness and speed. An outward Poisson integration is employed to increase accuracy in the core region, allowing absolute accuracies of 10(-8) Hartree to be attained for total energies of heavy atoms such as uranium. Detailed convergence studies are presented and computational parameters are provided to achieve accuracies commonly required in practice. Comparisons to analytic and current-benchmark density-functional results for atomic number Z = 1-92 are presented, verifying and providing a refinement to current benchmarks. An efficient, modular Fortran 95 implementation, dftatom, is provided as open source, including examples, tests, and wrappers for interface to other languages; wherein particular emphasis is placed on the independence (no global variables), reusability, and generality of the individual routines.

To judge the overall performance of divergence-free mixed finite elements, we investigate linear solvers for the saddle point linear systems arising in ((P-k)(d), P-k-1(disc)) Scott-Vogelius finite element implementations of the incompressible Navier-Stokes equations. We investigate both direct and iterative solver methods. Due to discontinuous pressure elements in the case of Scott-Vogelius (SV) elements, considerably more solver strategies seem to deliver promising results than in the case of standard mixed finite elements such as Taylor-Hood elements. For direct methods, we extend recent preliminary work using sparse banded solvers on the penalty method formulation to finer meshes and discuss extensions. For iterative methods, we test augmented Lagrangian and H-LU preconditioners with GMRES, on both full and statically condensed systems. Several numerical experiments are provided that show these classes of solvers are well suited for use with SV elements and could deliver an interesting overall performance in several applications.

TI Bridging the gap between HRA research and HRA practice: A Bayesian network version of SPAR-H SO RELIABILITY ENGINEERING & SYSTEM SAFETY LA English DT Article DE Human reliability analysis (HRA); Bayesian network (BN); SPAR-H; Causality; Context uncertainty ID HUMAN RELIABILITY-ANALYSIS; BELIEF NETWORKS; VALIDATION; SYSTEMS AB The shortcomings of Human Reliability Analysis (HRA) have been a topic of discussion for over two decades. Repeated attempts to address these limitations have resulted in over 50 HRA methods, and the HRA research community continues to develop new methods. However, there remains a gap between the methods developed by HRA researchers and those actually used by HRA practitioners. Bayesian Networks (BNs) have become an increasingly popular part of the risk and reliability analysis framework over the past decade. BNs provide a framework for addressing many of the shortcomings of HRA from a researcher perspective and from a practitioner perspective. Several research groups have developed advanced HRA methods based on BNs, but none of these methods has been adopted by HRA practitioners in the U.S. nuclear power industry or at the U.S. Nuclear Regulatory Commission. In this paper we bridge the gap between HRA research and HRA practice by building a BN version of the widely used SPAR-H method. We demonstrate how the SPAR-H BN can be used by HRA practitioners, and we also demonstrate how it can be modified to incorporate data and information from research to advance HRA practice. The SPAR-H BN can be used as a starting point for translating HRA research efforts and advances in scientific understanding into real, timely benefits for HRA practitioners. (C) 2013 Elsevier Ltd.

Flexibility of these residues has been suspected to be a key player in controlling the ligand traversal in the gorge. This raises the question of whether the over-representation of aromatic residues in the gorge implies higher-than-normal flexibility of these residues. The current study suggests that it does not. Large changes in the hydrophobic cross-sectional area due to dihedral oscillations are probably the reason of their presence in the gorge.

G. Mitri, J. Appl. Phys. 109 (2011) 014916] to the generalized case of arbitrary scattering from a fluid sphere placed off-axially. The scattered pressure is expressed using a generalized partial-wave series expansion involving the beam-shape coefficients (BSCs), the scattering coefficients of the fluid sphere, and the half-conical angle of the beam. The BSCs are evaluated using the numerical discrete spherical harmonics transform (DSHT). The properties of the off-axial acoustic scattering by a fluid red blood sphere (RBS), chosen as an example to illustrate the analysis, are discussed. 3D numerical computations for the directivity patterns in the near and far-field regions reveal unexplored phenomena that may be useful in applications related to particle entrapment, manipulation or rotation of soft matter using acoustic HOBTBs. Other potential applications may include medical or nondestructive ultrasound imaging with contrast agents, or monitoring of the manufacturing processes of sample soft matter systems with HOBTBs.

TI Determination of acoustical nonlinear parameter beta of water using the finite amplitude method SO ULTRASONICS LA English DT Article DE Nonlinear acoustics; Water ID PLANE SOUND-WAVES; BIOLOGICAL MEDIA; HARMONIC-GENERATION; ELASTIC-CONSTANTS; B/A; MIXTURES AB The acoustic nonlinearity of water is investigated using a variation of the finite amplitude method with harmonic generation. The finite amplitude method provides information on the coefficient of nonlinearity, beta, through the ratio of the amplitude of the fundamental and that of the second harmonic. The pressure of both the fundamental, p(1), and that of the second harmonic, p(2), are determined experimentally at different transmitter-receiver separation distances, eliminating the need for knowledge of the sound absorption in the medium. It was found that the experimental relationship between the slope of p(2)(x)/p(1)(2)(x) and transmitter-receiver separation distance, x, follows a linear relationship only in the near-field, in good agreement with theoretical predictions. A beta of 3.5 +/- 0.1 is determined for water at room temperature, in good agreement with previous results from both the isentropic equation of state and finite amplitude method.

TI Composite organic radical-inorganic hybrid cathode for lithium-ion batteries SO JOURNAL OF POWER SOURCES LA English DT Article DE Hybrid cathode; PTMA/LiFePO4 composite; High pulse power; Organic radical; Lithium-ion battery ID RECHARGEABLE BATTERIES; BEHAVIOR; ELECTRODES; POLYMERS AB A new organic radical-inorganic hybrid cathode comprised of poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl methacrylate) (PTMA)/LiFePO4 composite system was developed and reported for the first time. The hybrid electrodes' voltammetry contains three pairs of reversible redox peaks indicating the combination of electrochemical characteristics between LiFePO4 and PTMA electrodes and shows a decrease in voltage gap between oxidation and reduction that corresponds to an improvement in the rate and reversibility of the redox couples. Results from electrochemical impedance spectroscopy show lower charge-transfer resistance of cycled hybrid cathodes suggesting an enhanced electrode/electrolyte interface formed in hybrid systems which leads to faster migration of Li ions through the interface and longer cycle life capability when compared with pure LiFePO4 or PTMA cathode system. Optimizing the hybrid cathode's ratio of PTMA/LiFePO4 yields a significant improvement in high pulse power performance (30 mAh cm(-3)) over the pure PTMA (16 mAh cm(-3)) or LiFePO4 (3.0 mAh cm(-3)) cathode. Further characterization of the hybrid electrodes using SEM showed a more compact surface morphology after high rate pulse experiments. The demonstrated properties of hybrid cathodes are promising for transportation and other high pulse power applications that require long cycle life and low cost. (C) 2013 Published by Elsevier B.V.

A total three-dimensional volume of similar to 38,500 mu m(3) was imaged, from which Ni-YSZ anode functional layer (similar to 3650 mu m(3)) and LSM-YSZ cathode functional layer (similar to 4100 mu m(3)) volumes were reconstructed. These were among the largest-volume electrode reconstructions ever reported, while at the same time exhibiting high spatial resolution of 50 nm. Comparison with electrode microstructures measured using other imaging methods demonstrates that the larger NANO-TXM-measured volumes provided significantly more accurate phase connectivity information. A microstructure-based electrochemical model prediction agreed well with the measured full-cell electrochemical data. The results suggest that low LSM connectivity and slow oxygen reduction reaction kinetics in the cathode were a major limitation to the overall cell performance. (C) 2013 Elsevier B.V.

Three different organic acids, namely citric acid, malic acid and aspartic acid, are used as leaching reagents in the presence of hydrogen peroxide. The cathode active materials before and after acid leaching are characterized by X-ray diffraction and scanning electron microscopy. Recovery of cobalt and lithium is optimized by varying the leachant and H2O2 concentrations, the solid-to-liquid ratio, and the reaction temperature and duration. Whereas leaching with citric and malic acids recovered in excess of 90% of cobalt and lithium, leaching with aspartic acid recovered significantly less of these metals. The leaching mechanism likely begins with the dissolution of the active material (LiCoO2) in the presence of H2O2 followed by chelation of Co(II) and Li with citrate, malate or aspartate. An environmental analysis of the process indicates that it may be less energy and greenhouse gas intensive to recover Co from spent LIBs than to produce virgin cobalt oxide. (C) 2013 Elsevier B.V.

Their performance can be effectively improved by modifying the positive electrode. The positive composite electrodes are modified here in two different ways: by (i) alumina coatings of up to similar to 4 nm applied via atomic layer deposition (ALD), and (ii) addition of nanoscale alumina powder. Thicknesses of the ALD coatings are estimated via X-ray photoelectron spectroscopy (XPS). Electrochemical cycling reveals that capacity retention is better, and impedance rise is smaller for cells containing ALD-coated electrodes. Cells with alumina-powder modified electrodes show also improved capacity retention, but without improvements in impedance. Improved capacity retention is primarily due to reduced Li trapping on the negative electrode. Lower impedance growth, in ALD modified cells, is attributed to improved electro-mechanical integrity and altered surface films inside the positive electrode. The alumina coating inhibits, but does not prevent, transition metal dissolution. The coating also reduces electrolyte oxidation. Significant accumulation of Al on the negative electrode indicates electrochemical crosstalk between the electrodes and chemical instability of the ALD coatings during extended cycling.

ZrB2 with 20 vol.% SiC had room temperature strength of 700 +/- 90 MPa, fracture toughness of 6.4 +/- 0.6 MPa, Vickers hardness at 9.8N load of 21.1 +/- 0.6 GPa, 1400 degrees C strength of 400 +/- 30 MPa and room temperature strength after 1 h oxidation at 1400 degrees C of 678 +/- 15 MPa with an oxide layer thickness of 45 +/- 5 mu m. HfB2 with 20 vol.% SiC showed room temperature strength of 620 +/- 50 MPa, fracture toughness of 5.0 +/- 0.4 MPa, Vickers hardness at 9.8 N load of 27.0 +/- 0.6 GPa, 1400 degrees C strength of 590 +/- 150 MPa and room temperature strength after 1 h oxidation at 1400 degrees C of 660 +/- 25 MPa with an oxide layer thickness of 12 +/- 1 mu m. 2 wt.% La2O3 addition to UHTCs slightly reduced mechanical performance while increasing tolerance to property degradation after oxidation and effectively aided internal stress relaxation during spark plasma sintering (SPS) cooling, as quantified by X-ray diffraction (XRD). Slow crack growth was suggested as the failure mechanism at high temperatures as a consequence of sharp cracks formation during oxidation. (C) 2013 Elsevier Ltd. All rights reserved.

Flow is confined by two flat plates separated by a distance of 2a or by a tube with a radius of a (Figure 1). The standard advection-diffusion equation is mapped onto the boundary (r=a and r=0, where r is the distance from the centerline shown in Figure 1). The original problem of solving c(x,r,t) is reduced to solve the solutions of c at the boundary, and the problem dimensionality is reduced from 3 to 2. Final results show that the boundary concentration ca(x,t)=c(x, r=a,t) is advected at the mean velocity with a dispersion equal to the molecular diffusion. The centerline concentration c0(x,t)=c(x,r=0,t) is also advected at the mean velocity, but with a dispersion much larger than the Taylor dispersion. The cross-sectional average concentration is in agreement with the classical Taylor dispersion by neglecting higher order contributions. This study is relevant to the upscaling of solute transport.

The effect of the lower potential pulse duration (t(1)) of the electrodeposition on the surface morphology and structure of the Pt particles was investigated by the X-ray diffraction and scanning electron microscopy. The amount of the Pt loading was determined by an inductively coupled plasma method, and the electrocatalytic activity of the prepared Pt electrocatalysts on the ITO for the methanol oxidation was characterized by cyclic voltammetry. The results showed that the A has a significant influence on the surface morphology of the Pt particles on the ITO substrate. As the t(1) decreases from 1 to 0.01 s, the deposited Pt particles on the ITO exhibit flower-, nanosheet-, prickly and smooth spherical-like morphology in turn. Furthermore, there is a remarkable effect of the surface morphology of the Pt particles on the electrocatalytic activity for the methanol oxidation. Among all these morphologies, the flower- and nanosheet-like Pt particles on the ITO have a much higher mass specific activity (MA) for the methanol oxidation, and the Pt particles with prickly surface followed while the smooth spherical Pt particles have the lowest MA. In particular, the dispersed Pt nanosheets prepared at t(1) of 0.5 s has the highest MA. The much improved MA of the dispersed Pt nanosheets is attributed not only to the large electrochemically active surface area (ECSA) achieved, but also to the high electrocatalytic activity per unit ECSA related to its special morphology.

TI FUNDAMENTAL CONSTRAINTS ON LINEAR RESPONSE THEORIES OF FERMI SUPERFLUIDS ABOVE AND BELOW T-c SO INTERNATIONAL JOURNAL OF MODERN PHYSICS B LA English DT Review DE BCS theory; linear response theory; BCS-BEC crossover; gauge invariance; superfluids; Fermi gases; pairing fluctuations ID SUPERCONDUCTIVITY; GAS; TEMPERATURE AB We present fundamental constraints required for a consistent linear response theory of fermionic superfluids and address temperatures both above and below the transition temperature Tc. We emphasize two independent constraints, one associated with gauge invariance (and the related Ward identity) and another associated with the compressibility sum rule, both of which are satisfied in strict BCS theory. However, we point out that it is the rare many body theory which satisfies both of these. Indeed, well studied quantum Hall systems and random-phase approximations to the electron gas are found to have difficulties with meeting these constraints. We summarize two distinct theoretical approaches which are, however, demonstrably compatible with gauge invariance and the compressibility sum rule. The first of these involves an extension of BCS theory to a mean field description of the BCS-Bose Einstein condensation crossover. The second is the simplest Nozieres Schmitt-Rink (NSR) treatment of pairing correlations in the normal state. As a point of comparison we focus on the compressibility kappa of each and contrast the predictions above Tc. We note here that despite the compliance with sum rules, this NSR based scheme leads to an unphysical divergence in kappa at the transition. Because of the delicacy of the various consistency requirements, the results of this paper suggest that avoiding this divergence may repair one problem while at the same time introducing others.

Evaporative self-assembly of micro particles in picoliter droplets is enabled by a droplet-printing system for small-scale particle suspension droplets. Experiments were performed to study the regime where particle interactive forces become comparable to hydrodynamic, evaporative forces of an evaporating droplet. A particle-based computational method was developed to calculate the particle-to-particle clustering time. In this study, we verify that there is a time-scale competition between particle-to-particle clustering and evaporation of the liquid medium that determines the final morphology of micro particle assemblies.

Demonstrated here is the on-line coupling of such a probe with high-performance liquid chromatography/mass spectrometry (HPLC/MS) enabling extraction, separation and detection of small molecules and proteins from surfaces in a spatially resolved (similar to 0.5 mm diameter spots) manner. METHODS A continuous-flow liquid microjunction surface sampling probe was connected to a six-port, two-position valve for extract collection and injection to an HPLC column. A QTRAP (R) 5500 hybrid triple quadrupole linear ion trap equipped with a Turbo V ion source operated in positive electrospray ionization (ESI) mode was used for all experiments. The system operation was tested with the extraction, separation and detection of propranolol and associated metabolites from drug dosed tissues, caffeine from a coffee bean, cocaine from paper currency, and proteins from dried sheep blood spots on paper. RESULTS Confirmed in the tissue were the parent drug and two different hydroxypropranolol glucuronides. The mass spectrometric response for these compounds from different locations in the liver showed an increase with increasing extraction time (5, 20 and 40 s). For on-line separation and detection/identification of extracted proteins from dried sheep blood spots, two major protein peaks dominated the chromatogram and could be correlated with the expected masses for the hemoglobin and chains. CONCLUSIONS Spatially resolved sampling, separation, and detection of small molecules and proteins from surfaces can be accomplished using a continuous-flow liquid microjunction surface sampling probe coupled on-line with HPLC/MS detection.

In ReALE, we replace the rezoning phase of classical ALE method by a rezoning where we allow the connectivity between cells of the mesh to change. This leads to a polygonal mesh that recovers the Lagrangian features in order to follow more efficiently the flow. Those reconnections allow to deal with complex geometries and high vorticity problems contrary to ALE method. For optimizing the remapping phase, we have modified the idea of swept-integration-based. The new method is called swept-intersection-based remapping method. We demonstrate that our method can be applied to several numerical examples representative of hydrodynamic experiments.Copyright (c) 2012 John Wiley & Sons, Ltd.

The mean ionization state (MIS), i.e, the mean charge Z of an average ion in such plasmas, is a valuable concept: Pseudopotentials, pair-distribution functions, equations of state, transport properties, energy-relaxation rates, opacity, radiative processes, etc., can all be formulated using the MIS of the plasma more concisely than with an all-electron description. However, the MIS does not have a unique definition and is used and defined differently in different statistical models of plasmas. Here, using the MIS formulations of several average-atom models based on density functional theory, we compare numerical results for Be, Al, and Cu plasmas for conditions inclusive of incomplete atomic ionization and partial electron degeneracy. By contrasting modern orbital-based models with orbital-free Thomas-Fermi models, we quantify the effects of shell structure, continuum resonances, the role of exchange and correlation, and the effects of different choices of the fundamental cell and boundary conditions. Finally, the role of the MIS in plasma applications is illustrated in the context of x-ray Thomson scattering in warm dense matter.

The exponential growth of data generated in biology research, from small atoms to big ecosystems, necessitates an increasingly large computational component to perform analyses. Novel DNA sequencing technologies and complementary high-throughput approaches-such as proteomics, genomics, metabolomics, and meta-genomics-drive data-intensive bioinformatics. While individual research centers or universities could once provide for these applications, this is no longer the case. Today, only specialized national centers can deliver the level of computing resources required to meet the challenges posed by rapid data growth and the resulting computational demand. Consequently, we are developing massively parallel applications to analyze the growing flood of biological data and contribute to the rapid discovery of novel knowledge. Methods: The efforts of previous National Science Foundation (NSF) projects provided for the generation of parallel modules for widely used bioinformatics applications on the Kraken supercomputer. We have profiled and optimized the code of some of the scientific community's most widely used desktop and small-cluster-based applications, including BLAST from the National Center for Biotechnology Information (NCBI), HMMER, and MUSCLE; scaled them to tens of thousands of cores on high-performance computing (HPC) architectures; made them robust and portable to next-generation architectures; and incorporated these parallel applications in science gateways with a web-based portal. Results: This paper will discuss the various developmental stages, challenges, and solutions involved in taking bioinformatics applications from the desktop to petascale with a front-end portal for very-large-scale data analysis in the life sciences. Conclusions: This research will help to bridge the gap between the rate of data generation and the speed at which scientists can study this data. The ability to rapidly analyze data at such a large scale is having a significant, direct impact on science achieved by collaborators who are currently using these tools on supercomputers.

TI Local structure of amorphous GaN1-xAsx semiconductor alloys across the composition range SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID ABSORPTION FINE-STRUCTURE; RANDOM SOLID-SOLUTIONS; SOLAR-CELL; A-SI; FILMS; BAND; SPECTROSCOPY; CRYSTALLINE; GA1-XINXAS; EXAFS AB Typically only dilute (up to similar to 10%) highly mismatched alloys can be grown due to the large differences in atomic size and electronegativity of the host and the alloying elements. We have overcome the miscibility gap of the GaN1-xAsx system using low temperature molecular beam epitaxy. In the intermediate composition range (0.10 < x < 0.75), the resulting alloys are amorphous. To gain a better understanding of the amorphous structure, the local environment of the As and Ga atoms was investigated using extended x-ray absorption fine structure (EXAFS). The EXAFS analysis shows a high concentration of dangling bonds compared to the crystalline binary endpoint compounds of the alloy system. The disorder parameter was larger for amorphous films compared to crystalline references, but comparable with other amorphous semiconductors. By examining the Ga local environment, the dangling bond density and disorder associated with As-related and N-related bonds could be decoupled. The N-related bonds had a lower dangling bond density and lower disorder. (C) 2013 AIP Publishing LLC. C1 [Levander, A. X.; Yu, K. M.; Liliental-Weber, Z.; Dubon, O.

TI Phase and texture evolution in solution deposited lead zirconate titanate thin films: Formation and role of the Pt3Pb intermetallic phase SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID CHEMICAL SOLUTION DEPOSITION; CAPACITOR APPLICATIONS; CRYSTALLIZATION; PZT; TRANSFORMATION; DIFFRACTION; PYROCHLORE; TRANSITION; SILICON; LAYERS AB Solution deposition is widely used for the fabrication of lead zirconate titanate (PZT) thin films on platinized silicon substrates. However, phase and texture evolution during the crystallization process is not well understood, particularly due to the difficulty in tracking changes in the thin films in situ during heating. In this work, we characterized phase and texture evolution in situ during heating and crystallization of PZT thin films using high-energy X-ray diffraction. Films were pyrolyzed at either 300 degrees C or 400 degrees C and heated at various rates between 0.5 degrees C/s and similar to 150 degrees C/s. For films that were pyrolyzed at 300 degrees C, the most rapid heating rates first induced strong intensities from a transient Pt3Pb phase. The Pt3Pb phase inherited the texture of the pre-existing platinum layer. Combined with other observations, the results suggest the conversion of the platinum to the intermetallic phase near the interface due to the interdiffusion of lead. In all experimental variations, the pyrochlore phase was observed to form concurrently with the disappearance of the Pt3Pb phase after which the perovskite phase ultimately crystallized. For films that were pyrolyzed at 400 degrees C, the Pt3Pb phase was not observed at any of the heating rates; instead, the pyrochlore phase was first observed, followed by the perovskite phase. Independent of the pyrolysis temperature or observation of Pt3Pb, a 111-dominant crystallographic texture formed in the perovskite phase when crystallized using fast heating rates. These results demonstrate that 111 textures in solution-derived PZT thin films are not correlated with the observation of Pt3Pb or other intermetallic or transient phases.

TI Sound velocities for hexagonally close-packed iron compressed hydrostatically to 136GPa from phonon density of states SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article DE sound velocity; NRIXS; hydrostatic; hcp-iron ID EARTHS INNER-CORE; HIGH-PRESSURE; LIGHT-ELEMENTS; BIRCHS LAW; HCP-IRON; GPA; FE; DIFFRACTION; GIGAPASCALS; ELASTICITY AB The phonon density of states of pure iron (Fe-57) was measured under hydrostatic conditions using nuclear resonant inelastic X-ray scattering (NRIXS) at pressures up to 136GPa. Extracting shear (V-s) and compressional (V-p) wave speeds from the Debye velocity and equation of state, we find the hydrostatic shear wave speed trend above previously collected NRIXS data under nonhydrostatic conditions by roughly 5%-6% in the measured pressure range. Using the Birch Murnaghan finite strain approach to fit pressure-dependent adiabatic bulk and shear moduli, we extrapolated our velocities to inner Earth core densities and found that our shear wave speeds are 3% higher than those in previous studies. Our results on pure iron provide a more accurate and precise baseline to which added complications (e.g., Ni concentration, inclusion of various light elements, and temperature effects) can be considered when comparing experimental elasticity measurements to inner core seismic data.

TI Recurrence statistics of great earthquakes SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article DE earthquake clustering; statistical seismology; earthquake hazard ID CALIFORNIA; SEQUENCE AB We investigate the sequence of great earthquakes over the past century. To examine whether the earthquake record includes temporal clustering, we identify aftershocks and remove those from the record. We focus on the recurrence time, defined as the time between two consecutive earthquakes. We study the variance in the recurrence time and the maximal recurrence time. Using these quantities, we compare the earthquake record with sequences of random events, generated by numerical simulations, while systematically varying the minimal earthquake magnitude M-min. Our analysis shows that the earthquake record is consistent with a random process for magnitude thresholds 7.0M(min)8.3, where the number of events is larger. Interestingly, the earthquake record deviates from a random process at magnitude threshold 8.4M(min)8.5, where the number of events is smaller; however, this deviation is not strong enough to conclude that great earthquakes are clustered. Overall, the findings are robust both qualitatively and quantitatively as statistics of extreme values and moment analysis yield remarkably similar results.

SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article DE diurnal variability of aerosol; remote sensing; time-averaged direct aerosol radiative forcing; Two-Column Aerosol Project (TCAP) ID VARIABILITY; ATMOSPHERE AB Strong diurnal variability of aerosol has been observed frequently for many urban/industrial regions. How this variability may alter the direct aerosol radiative forcing (DARF), however, is largely unknown. To quantify changes in the time-averaged DARF, we perform an assessment of 29days of high temporal resolution ground-based data collected during the Two-Column Aerosol Project on Cape Cod, which is downwind of metropolitan areas. We demonstrate that strong diurnal changes of aerosol loading (about 20% on average) have a negligible impact on the 24-h average DARF when daily averaged optical properties are used to find this quantity. However, when there is a sparse temporal sampling of aerosol properties, which may preclude the calculation of daily averaged optical properties, large errors (up to 100%) in the computed DARF may occur. We describe a simple way of reducing these errors, which suggests the minimal temporal sampling needed to accurately find the forcing.

Compared to initial simulations, this leads to reductions in the mass of emitted dust particles with radii <1.8 mu m by 40%-60%. Consequently, the root-mean-square error in simulated fine dust concentrations compared to springtime surface observations in the western United States is reduced by 67%-81%. The ratio of simulated fine to coarse PM mass is also improved, which is not achievable by reductions in total dust emissions. The IMP_PSD best represents the PSD of dust transported from remote sources and reduces modeled PM2.5 concentrations up to 5 mu g/m(3) over the western United States, which is important when considering sources contributing to nonattainment of air quality standards.

Despite great academic and medical interest, the structures of these oligomers have not been well characterized. Site-directed spin labeling combined with electron paramagnetic resonance spectroscopy is a powerful approach for studying structurally ill-defined systems, but its application in amyloid oligomer structure study has not been systematically explored. Here we report a comprehensive structural study on a toxic A beta 42 oligomer, called globulomer, using site-directed spin labeling complemented by other techniques. Transmission electron microscopy shows that these oligomers are globular structures with diameters of similar to 7-8 nm. Circular dichroism shows primarily beta-structures. X-ray powder diffraction suggests a highly ordered intrasheet hydrogen-bonding network and a heterogeneous intersheet packing. Residue-level mobility analysis on spin labels introduced at 14 different positions shows a structured state and a disordered state at all labeling sites. Side chain mobility analysis suggests that structural order increases from N- to C-terminal regions. Intermolecular distance measurements at 14 residue positions suggest that C-terminal residues Gly-29-Val-40 form a tightly packed core with intermolecular distances in a narrow range of 11.5-12.5 angstrom. These intermolecular distances rule out the existence of fibril-like parallel in-register beta-structures and strongly suggest an antiparallel beta-sheet arrangement in A beta 42 globulomers.

TI Elastomeric microparticles for acoustic mediated bioseparations SO JOURNAL OF NANOBIOTECHNOLOGY LA English DT Article DE Cell separation; Continuous cell sorting; Acoustofluidics; Particle synthesis; Ultrasound standing wave ID MICROFLUIDIC CHANNELS; POLY(DIMETHYLSILOXANE); SEPARATION; PARTICLES; FLOW; ACOUSTOPHORESIS; MICROCHANNELS; CELLS AB Background: Acoustophoresis has been utilized successfully in applications including cell trapping, focusing, and purification. One current limitation of acoustophoresis for cell sorting is the reliance on the inherent physical properties of cells (e.g., compressibility, density) instead of selecting cells based upon biologically relevant surface-presenting antigens. Introducing an acoustophoretic cell sorting approach that allows biochemical specificity may overcome this limitation, thus advancing the value of acoustophoresis approaches for both the basic research and clinical fields. Results: The results presented herein demonstrate the ability for negative acoustic contrast particles (NACPs) to specifically capture and transport positive acoustic contrast particles (PACPs) to the antinode of an ultrasound standing wave. Emulsification and post curing of pre-polymers, either polydimethylsiloxane (PDMS) or polyvinylmethylsiloxane (PVMS), within aqueous surfactant solution results in the formation of stable NACPs that focus onto pressure antinodes. We used either photochemical reactions with biotin-tetrafluorophenyl azide (biotin-TFPA) or end-functionalization of Pluronic F108 surfactant to biofunctionalize NACPs. These biotinylated NACPs bind specifically to streptavidin polystyrene microparticles (as cell surrogates) and transport them to the pressure antinode within an acoustofluidic chip. Conclusion: To the best of our knowledge, this is the first demonstration of using NACPs as carriers for transport of PACPs in an ultrasound standing wave. By using different silicones (i.e., PDMS, PVMS) and curing chemistries, we demonstrate versatility of silicone materials for NACPs and advance the understanding of useful approaches for preparing NACPs. This bioseparation scheme holds potential for applications requiring rapid, continuous separations such as sorting and analysis of cells and biomolecules. C1 [Johnson, Leah M.; Shields, C.

The microbial production of hydroxycinnamoyl anthranilates is an eco-friendly alternative to chemical synthesis or purification from plant sources. We recently demonstrated in yeast (Saccharomyces cerevisiae) that coexpression of 4-coumarate: CoA ligase (4CL) from Arabidopsis thaliana and hydroxycinnamoyl/benzoyl-CoA/anthranilate N-hydroxycinnamoyl/benzoyltransferase (HCBT) from Dianthus caryophyllusenabled the biological production of several cinnamoyl anthranilates upon feeding with anthranilate and various cinnamates. Using engineering strategies to overproduce anthranilate and hydroxycinnamates, we describe here an entire pathway for the microbial synthesis of two Avns from glucose in Escherichia coli. Results: We first showed that coexpression of HCBT and Nt4CL1 from tobacco in the E. coli anthranilate-accumulating strain W3110 trpD9923 allowed the production of Avn D [N-(4'-hydroxycinnamoyl)-anthranilic acid] and Avn F [N-(3',4'-dihydroxycinnamoyl)-anthranilic acid] upon feeding with p-coumarate and caffeate, respectively. Moreover, additional expression in this strain of a tyrosine ammonia-lyase from Rhodotorula glutinis (RgTAL) led to the conversion of endogenous tyrosine into p-coumarate and resulted in the production of Avn D from glucose. Second, a 135-fold improvement in Avn D titer was achieved by boosting tyrosine production using two plasmids that express the eleven genes necessary for tyrosine synthesis from erythrose 4-phosphate and phosphoenolpyruvate. Finally, expression of either the p-coumarate 3-hydroxylase Sam5 from Saccharothrix espanensis or the hydroxylase complex HpaBC from E. coli resulted in the endogenous production of caffeate and biosynthesis of Avn F. Conclusion: We established a biosynthetic pathway for the microbial production of valuable hydroxycinnamoyl anthranilates from an inexpensive carbon source. The proposed pathway will serve as a platform for further engineering toward economical and sustainable bioproduction of these pharmaceuticals and other related aromatic compounds.

The total and triple-differential cross sections for the ground state are in good agreement with available calculations. We also used the time-dependent close-coupling method to calculate fully differential nuclear-recoil cross sections of He2+ for the two-photon double ionization of He in the ground and excited states at the same photon energies. The nuclear-recoil differential cross sections of He2+ for the ground state are in good agreement with the measurements recorded with a reaction microscope at the free-electron laser facility in Hamburg (FLASH).

TI Measurement of Radiative Proton Capture on F-18 and Implications for Oxygen-Neon Novae SO PHYSICAL REVIEW LETTERS LA English DT Article ID REACTION-RATES; CLASSICAL NOVAE; ISAC AB The rate of the F-18(p, gamma)Ne-19 reaction affects the final abundance of the gamma-ray observable radioisotope F-18, produced in novae. However, no successful measurement of this reaction exists and the rate used is calculated from incomplete information on the contributing resonances. Of the two resonances thought to play a significant role, one has a radiative width estimated from the assumed analogue state in the mirror nucleus, F-19. The second does not have an analogue state assignment at all, resulting in an arbitrary radiative width being assumed. Here, we report the first successful direct measurement of the F-18(p, gamma)Ne-19 reaction. The strength of the 665 keV resonance (E-x = 7.076 MeV) is found to be over an order of magnitude weaker than currently assumed in nova models. Reaction rate calculations show that this resonance therefore plays no significant role in the destruction of F-18 at any astrophysical energy.

TI Mitigation of Alfven Activity in a Tokamak by Externally Applied Static 3D Fields SO PHYSICAL REVIEW LETTERS LA English DT Article AB The application of static magnetic field perturbations to a tokamak plasma is observed to alter the dynamics of high-frequency bursting Alfven modes that are driven unstable by energetic ions. In response to perturbations with an amplitude of delta B/B similar to 0.01 at the plasma boundary, the mode amplitude is reduced, the bursting frequency is increased, and the frequency chirp is smaller. For modes of weaker bursting character, the magnetic perturbation induces a temporary transition to a saturated continuous mode. Calculations of the perturbed distribution function indicate that the 3D perturbation affects the orbits of fast ions that resonate with the bursting modes. The experimental evidence represents an important demonstration of the possibility of controlling fast-ion instabilities through "phase-space engineering" of the fast-ion distribution function, by means of externally applied perturbation fields.

TI Mapping of unoccupied states and relevant bosonic modes via the time-dependent momentum distribution SO PHYSICAL REVIEW B LA English DT Article ID RESOLUTION COMPTON-SCATTERING; DENSITY-WAVE; ELECTRON AB The unoccupied states of complex materials are difficult to measure, yet they play a key role in determining their properties. We propose a technique that can measure the unoccupied states, called time-resolved Compton scattering, which measures the time-dependent momentum distribution (TDMD). Using a nonequilibrium Keldysh formalism, we study the TDMD for electrons coupled to a lattice in a pump-probe setup. We find a direct relation between temporal oscillations in the TDMD and the dispersion of the underlying unoccupied states, suggesting that both can be measured by time-resolved Compton scattering. We demonstrate the experimental feasibility by applying the method to a model of MgB2 with realistic material parameters. C1 [Kemper, A.

Ligand field calculations in D-4h symmetry show very good agreement with the transition metal L-2,L-3 XAS spectra. To successfully explain nominal Cr2+ L-2,L-3 XAS spectrum in CrF2, the inclusion of Cr+ and Cr3+ was needed implying the presence of a disproportionation reaction. The multiplet calculations were then modified to remove the structure of the 2p hole in the calculated M 2p -> 3d absorption spectra. These results for the 3d(n+1) states are in one to one correspondence with the leading edge structures found at the fluorine K edge. A direct comparison with the metal L-2,L-3 edges also indicates that there is evidence of the metal multiplet at the fluorine K pre-edge structures.

We find that PBE and HSE06 give similar results. Without functional groups, MXenes have magnetically ordered ground states. All the studied materials are metallic except for Ti2CO2, which we predict to be semiconducting. The calculated density of states at the Fermi level of the thicker MXenes (n >= 5) is much higher than for thin MXenes, indicating that properties such as electronic conductivity and surface chemistry will be different. In general, the carbides and nitrides behave differently with the same functional groups. C1 [Xie, Yu; Kent, P. R. C.] Oak Ridge Natl Lab, Ctr Nanophase Mat Sci, Oak Ridge, TN 37831 USA. [Kent, P. R.

We show that this source of emittance growth is correctable, even in space-charge dominated beams with significant transients induced by space-charge waves.

We determined 3 angstrom resolution x-ray crystal structures of EF-G complexed with a nonhydrolyzable guanosine 5'-triphosphate (GTP) analog and bound to the Escherichia coli ribosome in different states of ribosomal subunit rotation. The structures reveal that EF-G binding to the ribosome stabilizes switch regions in the GTPase active site, resulting in a compact EF-G conformation that favors an intermediate state of ribosomal subunit rotation. These structures suggest that EF-G controls the translocation reaction by cycles of conformational rigidity and relaxation before and after GTP hydrolysis. C1 [Pulk, Arto; Cate, Jamie H.

Several wave-cut scarps that at the time of deposition would have been horizontal are now draped over a warped surface with a maximum variation of 60 meters. We modeled dynamic topography by using mantle convection simulations that predict the amplitude and broad spatial distribution of this distortion. The results imply that dynamic topography and, to a lesser extent, glacial isostatic adjustment account for the current architecture of the coastal plain and proximal shelf. This confounds attempts to use regional stratigraphic relations as references for longer-term sea-level determinations. Inferences of Pliocene global sea-level heights or stability of Antarctic ice sheets therefore cannot be deciphered in the absence of an appropriate mantle dynamic reference frame.

TI Probing carrier lifetimes in photovoltaic materials using subsurface two-photon microscopy SO SCIENTIFIC REPORTS LA English DT Article ID TIME-RESOLVED PHOTOLUMINESCENCE; CDTE SINGLE-CRYSTALS; FLUORESCENCE MICROSCOPY; SURFACE RECOMBINATION; SOLAR-CELLS; GAAS; EFFICIENCY; RESOLUTION; GAN AB Accurately measuring the bulk minority carrier lifetime is one of the greatest challenges in evaluating photoactive materials used in photovoltaic cells. One-photon time-resolved photoluminescence decay measurements are commonly used to measure lifetimes of direct bandgap materials. However, because the incident photons have energies higher than the bandgap of the semiconductor, most carriers are generated close to the surface, where surface defects cause inaccurate lifetime measurements. Here we show that two-photon absorption permits sub-surface optical excitation, which allows us to decouple surface and bulk recombination processes even in unpassivated samples. Thus with two-photon microscopy we probe the bulk minority carrier lifetime of photovoltaic semiconductors. We demonstrate how the traditional one-photon technique can underestimate the bulk lifetime in a CdTe crystal by 10x and show that two-photon excitation more accurately measures the bulk lifetime. Finally, we generate multi-dimensional spatial maps of optoelectronic properties in the bulk of these materials using two-photon excitation.

Kim, Young-June TI Magnetic excitation spectrum of Na2IrO3 probed with resonant inelastic x-ray scattering SO PHYSICAL REVIEW B LA English DT Article AB The low energy excitations in Na2IrO3 have been investigated using resonant inelastic x-ray scattering (RIXS). A magnetic excitation branch can be resolved, whose dispersion reaches a maximum energy of about 35 meV at the Gamma point. The momentum dependence of the excitation energy is much larger along the Gamma-X direction compared to that along the Gamma-Y direction. The observed dispersion relation is consistent with a recent theoretical prediction based on the Heisenberg-Kitaev model. At high temperatures, we find large contributions from lattice vibrational modes to our RIXS spectra, suggesting that a strong electron-lattice coupling is present in Na2IrO3.

This was achieved through laser-induced melting and evaporation of CNT-deposited Si substrates using a continuous wavelength CO2 laser. The synthesis location of the CNT/Si structures was defined by the laser-irradiated spots. The thickness of the coating was controlled by tuning the laser power and synthesis time during the coating process. This laser-based synthetic technique provides a convenient approach for solid-state, controllable, gas-free, simple and cost-effective fabrication of CNT/Si core/shell structures.

Ti ions were implanted into fused silica, soda lime glass, Z-cut quartz, or (0001) alpha-sapphire by a metal vapor vacuum arc (MEVVA) ion source implanter to fluences of 0.75, 1.5 and 3 x 10(17) ions cm(-2) with a nominal accelerating voltage of 20 kV. To understand the influence of the annealing temperature, time, and substrate on the formation and phase transformation of the TiO2 nanofilms, the Ti-ion-implanted substrates were annealed in oxygen atmosphere from 500 to 1000 degrees C for 1-6 h. The formation of TiO2 nanofilms resulted from the slow out-diffusion of implanted Ti ions from the substrates which were then oxidized at the surfaces. The thickness and phase of the nanofilms can be tailored by controlling the implantation and annealing parameters. Since the TiO2 nanofilms are formed under high temperature and low growth rate, they show good crystallinity and antibacterial properties, with good film adhesion and stability, suggesting that the TiO2 nanofilms formed by this method have great potential in applications such as antibacterial and self-cleaning transparent glass.

We searched for key factors that direct HSC to lymphopoiesis. Comparing gene expression profiles for HSCs and early lymphoid progenitors revealed that Satb1, a global chromatin regulator, was markedly induced with lymphoid lineage specification. HSCs from Satb1-deficient mice were defective in lymphopoietic activity in culture and failed to reconstitute T lymphopoiesis in wild-type recipients. Furthermore, Satb1 transduction of HSCs and embryonic stem cells robustly promoted their differentiation toward lymphocytes. Whereas genes that encode Ikaros, E2A, and Notch1 were unaffected, many genes involved in lineage decisions were regulated by Satb1. Satb1 expression was reduced in aged HSCs with compromised lymphopoietic potential, but forced Satb1 expression partly restored that potential. Thus, Satb1 governs the initiating process central to the replenishing of lymphoid lineages. Such activity in lymphoid cell generation may be of clinical importance and useful to overcome immunosenescence.

TI Hydrogen vehicles: Impacts of DOE technical targets on market acceptance and societal benefits SO INTERNATIONAL JOURNAL OF HYDROGEN ENERGY LA English DT Article DE Hydrogen; Alternative fuel vehicle; Energy; Greenhouse gas; Public policy; Electric vehicle ID PLUG-IN HYBRID AB Hydrogen vehicles (H2V), including H-2 internal combustion engine, fuel cell and fuel cell plug-in hybrid, could greatly reduce petroleum consumption and greenhouse gas (GHG) emissions in the transportation sector. The U.S. Department of Energy has adopted targets for vehicle component technologies to address key technical barriers to widespread commercialization of H(2)Vs. This study estimates the market acceptance of H(2)Vs and the resulting societal benefits and subsidy in 41 scenarios that reflect a wide range of progress in meeting these technical targets. Important results include: (1) H(2)Vs could reach 20-70% market shares by 2050, depending on progress in achieving the technical targets. With a basic hydrogen infrastructure (similar to 5% hydrogen availability), the H2V market share is estimated to be 2-8%. Fuel cell and hydrogen costs are the most important factors affecting the long-term market shares of H(2)Vs. (2) Meeting all technical targets on time could result in about an 80% cut in petroleum use and a 62% (or 72% with aggressive electricity de-carbonization) reduction in GHG in 2050. (3) The required hydrogen infrastructure subsidy is estimated to range from $22 to $47 billion and the vehicle subsidy from $4 to $17 billion. (4) Long-term H2V market shares, societal benefits and hydrogen subsidies appear to be highly robust against delay in one target, if all other targets are met on time. R&D diversification could provide insurance for greater societal benefits. (5) Both H(2)Vs and plug-in electric vehicles could exceed 50% market shares by 2050, if all targets are met on time. The overlapping technology, the fuel cell plug-in hybrid electric vehicle, appears attractive both in the short and long runs, but for different reasons.

TI Simulation of high-pressure liquid hydrogen releases SO INTERNATIONAL JOURNAL OF HYDROGEN ENERGY LA English DT Article DE Liquid hydrogen jet releases; Hydrogen codes and standards; Dilution distances ID FLOW AB Sandia National Laboratories is working with stakeholders to develop scientific data for use by standards development organizations to create hydrogen codes and standards for the safe use of liquid hydrogen. Knowledge of the concentration field and flammability envelope for high-pressure hydrogen leaks is an issue of importance for the safe use of liquid hydrogen. Sandia National Laboratories is engaged in an experimental and analytical program to characterize and predict the behavior of liquid hydrogen releases. This paper presents a model for computing hydrogen dilution distances for cold hydrogen releases. Model validation is presented for leaks of room temperature and 80 K high-pressure hydrogen gas. The model accounts for a series of transitions that occurs from a stagnate location in the tank to a point in the leak jet where the concentration of hydrogen in air at the jet centerline has dropped to 4% by volume. The leaking hydrogen is assumed to be a simple compressible substance with thermodynamic equilibrium between hydrogen vapor, hydrogen liquid and air. For the multi-phase portions of the jet near the leak location the REFPROP equation of state models developed by NIST are used to account for the thermodynamics. Further downstream, the jet develops into an atmospheric gas jet where the thermodynamics are described as a mixture of ideal gases (hydrogen-air mixture). Simulations are presented for dilution distances in under-expanded high-pressure leaks from the saturated vapor and saturated liquid portions of a liquid hydrogen storage tank at 10.34 barg (150 PSIG).

TI Hydrogen fuel-cell forklift vehicle releases in enclosed spaces SO INTERNATIONAL JOURNAL OF HYDROGEN ENERGY LA English DT Article DE Hydrogen fuel-cell forklift; Simulations; Experimental validation; Hydrogen codes and standards ID DYNAMICS AB Sandia National Laboratories has worked with stakeholders and original equipment manufacturers (OEMs) to develop scientific data that can be used to create risk-informed hydrogen codes and standards for the safe operation of indoor hydrogen fuel-cell forklifts. An important issue is the possibility of an accident inside a warehouse or other enclosed space, where a release of hydrogen from the high-pressure gaseous storage tank could occur. For such scenarios, computational fluid dynamics (CFD) simulations have been used to model the release and dispersion of gaseous hydrogen from the vehicle and to study the behavior of the ignitable hydrogen cloud inside the warehouse or enclosure. The overpressure arising as a result of ignition and subsequent deflagration of the hydrogen cloud within the warehouse has been studied for different ignition delay times and ignition locations. Both ventilated and unventilated warehouses have been considered in the analysis. Experiments have been performed in a scaled warehouse test facility and compared with simulations to validate the results of the computational analysis.

TI Modeling of sudden hydrogen expansion from cryogenic pressure vessel failure SO INTERNATIONAL JOURNAL OF HYDROGEN ENERGY LA English DT Article DE Room temperature pressure vessel; Cryogenic pressure vessel; Failure; Sudden release; Expansion energy ID STORAGE; VEHICLES; RELEASE; SIMULATION AB We have modeled sudden hydrogen expansion from a cryogenic pressure vessel. This model considers real gas equations of state, single and two-phase flow, and the specific "vessel within vessel" geometry of cryogenic vessels. The model can solve sudden hydrogen expansion for initial pressures up to 1210 bar and for initial temperatures ranging from 27 to 400 K. For practical reasons, our study focuses on hydrogen release from 345 bar, with temperatures between 62 K and 300 K. The pressure vessel internal volume is 151 L. The results indicate that cryogenic pressure vessels may offer a safety advantage with respect to compressed hydrogen vessels because i) the vacuum jacket protects the pressure vessel from environmental damage, ii) hydrogen, when released, discharges first into an intermediate chamber before reaching the outside environment, and working temperature is typically much lower and thus the hydrogen has less energy. Results indicate that key expansion parameters such as pressure, rate of energy release, and thrust are all considerably lower for a cryogenic vessel within vessel geometry as compared to ambient temperature compressed gas vessels. Future work will focus on taking advantage of these favorable conditions to attempt fail-safe cryogenic vessel designs that do not harm people or property even after catastrophic failure of the inner pressure vessel.

TI The response of coastal stratocumulus clouds to agricultural irrigation in California SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article DE irrigation; Stratocumulus; land surface model; general circulation model ID LOWER-TROPOSPHERIC STABILITY; TOPPED BOUNDARY-LAYERS; SUBTROPICAL STRATOCUMULUS; STRATIFORM CLOUDS; RADIATION BUDGET; SURFACE CLIMATE; UNITED-STATES; LAND-SURFACE; WATER CYCLE; MODEL AB Stratocumulus clouds (SC) often exist over the eastern subtropical oceans during the summer and have significant impacts on the surface radiation budget. Both atmospheric subsidence and lower troposphere stability (LTS) have been found to play important roles in maintaining SC. Using global climate model simulations, we find that irrigation in California's Central Valley results in a decrease of land surface temperature, leading to a smaller land-sea heat contrast, and a corresponding reduction in sea breeze, subsidence, and LTS over the near-coastal region. The decrease in LTS directly drives a reduction in modeled SC coverage, and it would arguably do so in reality because of the well-known link between LTS and SC coverage. Consequently, simulated absorbed surface solar radiation over this region increases by 8W/m(2) (3.7%) due to the reduction in SC cover, resulting in the warming at the Earth's surface. This study has important implications for how SC can change with regard to future climate. In contrast to the general effects of climate change on the formation of SC, our results suggest that irrigation practices in the Central Valley may drive a decrease in nearby SC coverage.

TI Evaluation of aerosol-cloud interaction in the GISS ModelE using ARM observations SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article DE climate model; aerosol cloud interactions; model evaluation; remote sensing ID GLOBAL CLIMATE MODELS; GENERAL-CIRCULATION MODEL; GROUND-BASED MEASUREMENTS; EFFECTIVE RADIUS; SATELLITE DATA; WATER CLOUDS; PARAMETERIZATION; MICROPHYSICS; SIMULATIONS; VAPOR AB Observations from the US Department of Energy's Atmospheric Radiation Measurement (ARM) program are used to evaluate the ability of the NASA GISS ModelE global climate model in reproducing observed interactions between aerosols and clouds. Included in the evaluation are comparisons of basic meteorology and aerosol properties, droplet activation, effective radius parameterizations, and surfacebased evaluations of aerosolcloud interactions (ACI). Differences between the simulated and observed ACI are generally large, but these differences may result partially from vertical distribution of aerosol in the model, rather than the representation of physical processes governing the interactions between aerosols and clouds. Compared to the current observations, the ModelE often features elevated droplet concentrations for a given aerosol concentration, indicating that the activation parameterizations used may be too aggressive. Additionally, parameterizations for effective radius commonly used in models were tested using ARM observations, and there was no clear superior parameterization for the cases reviewed here. This lack of consensus is demonstrated to result in potentially large, statistically significant differences to surface radiative budgets, should one parameterization be chosen over another.

The usefulness of SCM simulations are limited, however, by the accuracy of the best estimate large-scale observations prescribed. Errors estimating the observations will result in uncertainty in modeled simulations. One method to address the modeled uncertainty is to simulate an ensemble where the ensemble members span observational uncertainty. This study first derives an ensemble of large-scale data for the Tropical Warm Pool International Cloud Experiment (TWP-ICE) based on an estimate of a possible source of error in the best estimate product. These data are then used to carry out simulations with 11 SCM and two cloud-resolving models (CRM). Best estimate simulations are also performed. All models show that moisture-related variables are close to observations and there are limited differences between the best estimate and ensemble mean values. The models, however, show different sensitivities to changes in the forcing particularly when weakly forced. The ensemble simulations highlight important differences in the surface evaporation term of the moisture budget between the SCM and CRM. Differences are also apparent between the models in the ensemble mean vertical structure of cloud variables, while for each model, cloud properties are relatively insensitive to forcing. The ensemble is further used to investigate cloud variables and precipitation and identifies differences between CRM and SCM particularly for relationships involving ice. This study highlights the additional analysis that can be performed using ensemble simulations and hence enables a more complete model investigation compared to using the more traditional single best estimate simulation only.

The collected particles were analyzed using Computer Controlled Scanning Electron Microscopy with Energy Dispersive X-ray analysis and Scanning Transmission X-ray Microscopy coupled with Near Edge X-ray Absorption Fine Structure spectroscopy to identify physico-chemical properties that differentiate cloud-nucleating particles from the total aerosol population. A wide range of individually mixed components was identified in the ambient particles and residuals including organic carbon compounds, inorganics, carbonates, and black carbon. Our results show that cloud droplet residuals differ from the ambient particles in both size and composition, suggesting that both properties may impact the cloud-nucleating ability of aerosols in mixed-phase clouds. The percentage of residual particles which contained carbonates (47%) was almost four times higher than those in ambient samples. Residual populations were also enhanced in sea salt and black carbon and reduced in organic compounds relative to the ambient particles. Further, our measurements suggest that chemical processing of aerosols may improve their cloud-nucleating ability. Comparison of results for various time periods within ISDAC suggests that the number and composition of cloud-nucleating particles over Alaska can be influenced by episodic events bringing aerosols from both the local vicinity and as far away as Siberia.

TI A simple model of global aerosol indirect effects SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article DE aerosol; cloud; interactions; indirect; climate ID CLOUD CONDENSATION NUCLEI; GENERAL-CIRCULATION MODEL; CARBON-CYCLE MODELS; CLIMATE MODEL; ORGANIC AEROSOL; MARINE STRATOCUMULUS; UNCERTAINTY ANALYSIS; MICROPHYSICS MODEL; ATMOSPHERE-OCEAN; SENSITIVITY AB Most estimates of the global mean indirect effect of anthropogenic aerosol on the Earth's energy balance are from simulations by global models of the aerosol lifecycle coupled with global models of clouds and the hydrologic cycle. Extremely simple models have been developed for integrated assessment models, but lack the flexibility to distinguish between primary and secondary sources of aerosol. Here a simple but more physically based model expresses the aerosol indirect effect (AIE) using analytic representations of cloud and aerosol distributions and processes. Although the simple model is able to produce estimates of AIEs that are comparable to those from some global aerosol models using the same global mean aerosol properties, the estimates by the simple model are sensitive to preindustrial cloud condensation nuclei concentration, preindustrial accumulation mode radius, width of the accumulation mode, size of primary particles, cloud thickness, primary and secondary anthropogenic emissions, the fraction of the secondary anthropogenic emissions that accumulates on the coarse mode, the fraction of the secondary mass that forms new particles, and the sensitivity of liquid water path to droplet number concentration. Estimates of present-day AIEs as low as -5 W m(-2) and as high as -0.3 W m(-2) are obtained for plausible sets of parameter values. Estimates are surprisingly linear in emissions. The estimates depend on parameter values in ways that are consistent with results from detailed global aerosol-climate simulation models, which adds to understanding of the dependence on AIE uncertainty on uncertainty in parameter values.

Transport of pollutants emitted in one region to another region may add to the impact of local emissions. In this work, Lagrangian particle dispersion model simulations show the amounts of tracers that are transported within and among four regions, Southern California, the San Francisco Bay Area, the Central Valley, and the rest of the state. The simulations cover May and June of 2010, the California Research at the Nexus of Air Quality and Climate Change experiment period. Tracers of automobile emissions and one type of agricultural emission are used. Tracer mixing ratios are compared to airborne and ground-based measurements. The age of tracers in each location is also presented. Vertical profiles and diurnal cycles help to clarify the transport process. As is well known, Southern California emissions are transported to the east and affect the desert areas, and Bay Area automobile emissions are an important source of pollutants in the San Joaquin Valley. A novel result is that the Southern California Bight is filled with a mixture of well-aged carbon monoxide tracer from Southern California and the Bay Area. Air over the Bight is also affected by the agricultural emissions represented by the agricultural tracer, dominantly from the Central Valley where its sources are largest. There is no indication of transport from Southern California to the Central Valley. Emissions from the Central Valley do make their way to Southern California, as shown by the agricultural tracer, but automobile emissions from the Valley are insignificant in Southern California.

TI Detailed chemical characterization of unresolved complex mixtures in atmospheric organics: Insights into emission sources, atmospheric processing, and secondary organic aerosol formation SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article DE semivolatile organic compounds; secondary organic aerosol; urban emissions; unresolved complex mixture; gas chromatography mass spectrometry ID 2-DIMENSIONAL GAS-CHROMATOGRAPHY; AIR-POLLUTION SOURCES; DUTY DIESEL TRUCKS; MASS-SPECTROMETER; VOLATILITY DISTRIBUTION; N-ALKANES; SEMIVOLATILE; HYDROCARBONS; EVOLUTION; PHOTOOXIDATION AB Recent studies suggest that semivolatile organic compounds (SVOCs) are important precursors to secondary organic aerosol (SOA) in urban atmospheres. However, knowledge of the chemical composition of SVOCs is limited by current analytical techniques, which are typically unable to resolve a large number of constitutional isomers. Using a combination of gas chromatography and soft photoionization mass spectrometry, we characterize the unresolved complex mixture (UCM) of semivolatile aliphatic hydrocarbons observed in Pasadena, California (similar to 16km NE of downtown Los Angeles), and Bakersfield, California, during the California Research at the Nexus of Air Quality and Climate Change 2010. To the authors' knowledge, this work represents the most detailed characterization of the UCM in atmospheric samples to date. Knowledge of molecular structures, including carbon number, alkyl branching, and number of rings, provides important constraints on the rate of atmospheric processing, as the relative amounts of branched and linear alkanes are shown to be a function of integrated exposure to hydroxyl radicals. Emissions of semivolatile branched alkanes from fossil fuel-related sources are up to an order of magnitude higher than those of linear alkanes, and the gas-phase OH rate constants of branched alkanes are similar to 30% higher than their linear isomers. Based on a box model considering gas/particle partitioning, emissions, and reaction rates, semivolatile branched alkanes are expected to play a more important role than linear alkanes in the photooxidation of the UCM and subsequent transformations into SOA. Detailed speciation of semivolatile compounds therefore provides essential understanding of SOA sources and formation processes in urban areas. C1 [Chan, Arthur W.

The analysis revealed the striking difference in the influence of these ions on water dynamics. While the averaged water diffusion slows down in the presence of the structure making (kosmotrope) Na+ ion, the diffusion becomes faster in the presence of the structure breaking (chaotrope) K+ ion. The latter means that, despite strong Coulombic interactions introduced by the K+ ions, their disruption of the hydrogen-bonding network is so significant that it leads to faster diffusion of the water molecules.

TI Dynamics of Hydration Water in Sugars and Peptides Solutions SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID DEPOLARIZED LIGHT-SCATTERING; AMINO-ACID SOLUTIONS; AQUEOUS-SOLUTIONS; DIELECTRIC-RELAXATION; MODEL PEPTIDES; PROTEIN; GLUCOSE; REORIENTATION; SPECTROSCOPY; SIMULATIONS AB We analyzed solute and solvent dynamics of sugars and peptides aqueous solutions using extended depolarized light scattering (EDLS) and broadband dielectric spectroscopies (BDS). Spectra measured with both techniques reveal the same mechanism of rotational diffusion of peptides molecules. In the case of sugars, this solute reorientational relaxation can be isolated by EDLS measurements, whereas its contribution to the dielectric spectra is almost negligible. In the presented analysis, we characterize the hydration water in terms of hydration number and retardation ratio xi between relaxation times of hydration and bulk water. Both techniques provide similar estimates of xi. The retardation imposed on the hydration water by sugars is similar to 3.3 +/- 1.3 and involves only water molecules hydrogen-bonded (HB) to solutes (similar to 3 water molecules per sugar OH-group). In contrast, polar peptides cause longer range perturbations beyond the first hydration shell, and xi between 2.8 and 8, increasing with the number of chemical groups engaged in FIB formation. We demonstrate that chemical heterogeneity and specific HB interactions play a crucial role in hydration dynamics around polar solutes. The obtained results help to disentangle the role of excluded volume and enthalpic contributions in dynamics of hydration water at the interface with biological molecules.

A series of Ti-based intermetallic alloy (TiAl, Ti3Al, TiNi, TiFe, TiNb, TiMn2, and TiVMn)-doped MgH2 materials were systematically investigated in this study to improve its hydrogen storage properties. The dehydrogenation and hydrogenation properties were studied by using both thermogravimetric analysis and pressure-composition-temperature (PCT) isothermal to characterize the temperature of dehydrogenation and the kinetics of both desorption and absorption of hydrogen by these doped MgH2. Results show significant improvements of both dehydrogenation and hydrogenation kinetics as a result of adding the Ti intermetallic alloys as catalysts. In particular, the TiMn2-doped Mg demonstrated extraordinary hydrogen absorption capability at room temperature and 1 bar hydrogen pressure. The PCT experiments also show that the hydrogen equilibrium pressures of MgH2 were not affected by these additives.

In this study, we investigated the nature of Ru oxides on a Ru polycrystalline film under oxidizing, reducing, and catalytic CO oxidation reaction conditions. Thus, bulk Ru oxide was easily formed on such Ru catalysts, the growth of which was dependent on reaction temperature. Once formed, such an oxide is irreversible and cannot be completely removed even under reducing conditions at elevated temperatures (200 degrees C). Our reaction studies showed substantial deactivation of the Ru film during catalytic CO oxidation, and its activity could be partially recovered after reduction pretreatment. Such continuous deactivation of a Ru film is correlated with irreversibly formed bulk Ru oxide, as shown by AP-XPS. Such in situ spectroscopic evidence of the transition of oxides to a catalytically inactive state can enable more effective design of catalysts with less deactivation.

TI A Screened Hybrid DFT Study of Actinide Oxides, Nitrides, and Carbides SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID ELECTRONIC-STRUCTURE; URANIUM NITRIDE; UO2 AB A systematic study of the structural, electronic, and magnetic properties of actinide oxides, nitrides, and carbides (AnX(1-2) with X = C, N, O) is performed using the Heyd-Scuseria-Ernzerhof (HSE) hybrid functional. Our computed results show that the screened hybrid HSE functional gives a good description of the electronic and structural properties of actinide dioxides (strongly correlated insulators) when compared with available experimental data. However, there are still some problems reproducing the electronic properties of actinide nitrides and carbides (strongly correlated metals). In addition, in order to compare with the results by HSE, the structures, electronic, and magnetic properties of these actinide compounds are also investigated in the PBE and PBE+U approximation. Interestingly, the density of states of UN obtained with PBE compares well with the experimental photoemission spectra, in contrast to the hybrid approximation. This is presumably related to the need of additional screening in the Hartree-Fock exchange term of the metallic phases.

TI Quantifying the Solubility of Boron Nitride Nanotubes and Sheets with Static Light Scattering and Refractometry SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID WALLED CARBON NANOTUBES; POLYMER COMPOSITES; ORGANIC-SOLVENTS; DISPERSION; FUNCTIONALIZATION; PARAMETERS AB The dissolution of nanoparticles, particularly those containing boron, is an important area of interest for polymer nanocomposite formation and material development. In this work, the solubility of boron nitride nanotubes (BNNT), functionalized boron nitride nanotubes (FBNNT), and boron nitride sheets (BN-ZG) is quantified in toluene and THF with static light scattering, refractometry, UV-vis spectroscopy, and physical observations. UV-vis spectroscopy provides a method to determine the concentration and solubility limits of the solutions tested. Using light scattering, the second virial coefficient, A(2), is determined and used to calculate chi, the solute-solvent interaction parameter. The Hildebrand solubility parameter, delta, is then extracted from this data using the Hildebrand-Scatchard Solution Theory. A list of potential good solvents based on the estimated delta value is provided for each nanoparticle. Single-walled carbon nanotubes (SWNTs) and prepolymers (EN4 and EN8) used to synthesize polyurethanes were also tested, because the published delta and molar attraction constants of these materials provided a self-consistent check. The dn/dc of SWNTs and boron-containing particles was measured for the first time in this work. A solvent screen for BN-ZG provides additional information that supports the obtained delta and chi. Three systems were found to have chi values below 0.5 and were thermodynamically soluble: BNNT in THF, EN8 in THF, and EN8 in toluene. C1 [Mutz, M.; Dadmun, M.

TI Production of minimally entangled typical thermal states with the Krylov-space approach SO PHYSICAL REVIEW B LA English DT Article ID QUANTUM RENORMALIZATION-GROUPS; PHASE-TRANSITIONS; HUBBARD-MODEL; SYSTEMS; ABSENCE AB The minimally entangled typical thermal states algorithm is applied to fermionic systems using the Krylov-space approach to evolve the system in imaginary time. The convergence of local observables is studied in a tight-binding system with a site-dependent potential. The temperature dependence of the superconducting correlations of the attractive Hubbard model is analyzed on chains, showing an exponential decay with distance and exponents proportional to the temperature at low temperatures, as expected. In addition, the nonlocal parity correlator is calculated at finite temperature. Other possible applications of the minimally entangled typical thermal states algorithm to fermionic systems are also discussed.

Elementary phononic devices such as thermal rectifiers, transistors, and logic gates are essentially based on two intriguing properties: heat diode effect and negative differential thermal conductance. However, little is known about these heat transfer properties across metal-dielectric interfaces, especially at nanoscale. Here we analytically resolve the microscopic mechanism of the nonequilibrium nanoscale energy transfer across metal-dielectric interfaces, where the inelastic electron-phonon scattering directly assists the energy exchange. We demonstrate the emergence of heat diode effect and negative differential thermal conductance in nanoscale interfaces and explain why these novel thermal properties are usually absent in bulk metal-dielectric interfaces. These results will generate exciting prospects for the nanoscale interfacial energy transfer, which should have important implications in designing hybrid circuits for efficient thermal control and open up potential applications in thermal energy harvesting with low-dimensional nanodevices.

CA Belle Collaboration TI Search for B -> h(()*())nu(nu)over-bar with the full Belle Upsilon(4S) data sample SO PHYSICAL REVIEW D LA English DT Article ID DETECTOR AB We report a search for the rare decays B -> h(()*())nu(nu) over bar, where h(()*()) stands for K+, K-S(0), K*(+), K*(0), pi(+), pi(0), rho(+), rho(0) and phi. The results are obtained from a 711 fb(-1) 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 e(+)e(-) collider. We search for signal candidates by fully reconstructing a hadronic decay of the accompanying B meson and requiring a single h(()*()) meson left on the signal side. No significant signal is observed and we set upper limits on the branching fractions at 90% confidence level. The measurements of B+ -> K*(+)nu(nu) over bar, B+ -> pi(+)nu(nu) over bar, B-0 -> pi(0)nu(nu) over bar and B-0 -> rho(0)nu(nu) over bar provide the world's currently most restrictive limits.

TI Homes scaling and BCS SO PHYSICAL REVIEW B LA English DT Article ID TEMPERATURE; SUPERCONDUCTORS AB It is argued on the basis of the BCS theory that the zero-T penetration depth satisfies lambda(-2)(0) alpha sigma T-c (sigma is the normal state dc conductivity) not only in the extreme dirty limit xi(0)/l >> 1, but in a broad range of scattering parameters down to xi(0)/l similar to 1 (xi(0) is the zero-T BCS coherence length and l is the mean free path). Hence, the scaling lambda(-2)(0) alpha sigma T-c, sTc, suggested as a new universal property of superconductors [Dordevic, Basov, and Homes, Sci. Rep. 3, 1713 (2013)], finds a natural explanation within the BCS theory. C1 US DOE, Ames Lab, Ames, IA 50011 USA. RP Kogan, VG (reprint author), US DOE, Ames Lab, Ames, IA 50011 USA.

TI Compensating effect of the coherent synchrotron radiation in bunch compressors SO PHYSICAL REVIEW SPECIAL TOPICS-ACCELERATORS AND BEAMS LA English DT Article ID FREE-ELECTRON LASER; EXTREME-ULTRAVIOLET; OPERATION AB Typical bunch compression for a high-gain free-electron laser (FEL) requires a large compression ratio. Frequently, this compression is distributed in multiple stages along the beam transport line. However, for a high-gain FEL driven by an energy recovery linac (ERL), compression must be accomplished in a single strong compressor located at the beam line's end; otherwise the electron beam would be affected severely by coherent synchrotron radiation (CSR) in the ERL's arcs. In such a scheme, the CSR originating from the strong compressors could greatly degrade the quality of the electron beam. In this paper, we present our design for a bunch compressor that will limit the effect of CSR on the e-beam's quality. We discuss our findings from a study of such a compressor, and detail its potential for an FEL driven by a multipass ERL developed for the electron-Relativistic Heavy Ion Collider.

TI A Multi-Omic View of Host-Pathogen-Commensal Interplay in Salmonella-Mediated Intestinal Infection SO PLOS ONE LA English DT Article ID ENTERICA SEROVAR TYPHIMURIUM; MASS-SPECTROMETRY; MICROBIAL ECOLOGY; VIRULENCE FACTORS; MUCIN DYNAMICS; IMMUNE-SYSTEM; SP NOV.; RESISTANCE; PROTEIN; CELLS AB The potential for commensal microorganisms indigenous to a host (the 'microbiome' or 'microbiota') to alter infection outcome by influencing host-pathogen interplay is largely unknown. We used a multi-omics "systems'' approach, incorporating proteomics, metabolomics, glycomics, and metagenomics, to explore the molecular interplay between the murine host, the pathogen Salmonella enterica serovar Typhimurium (S. Typhimurium), and commensal gut microorganisms during intestinal infection with S. Typhimurium. We find proteomic evidence that S. Typhimurium thrives within the infected 129/SvJ mouse gut without antibiotic pre-treatment, inducing inflammation and disrupting the intestinal microbiome (e. g., suppressing Bacteroidetes and Firmicutes while promoting growth of Salmonella and Enterococcus). Alteration of the host microbiome population structure was highly correlated with gut environmental changes, including the accumulation of metabolites normally consumed by commensal microbiota. Finally, the less characterized phase of S. Typhimurium's lifecycle was investigated, and both proteomic and glycomic evidence suggests S. Typhimurium may take advantage of increased fucose moieties to metabolize fucose while growing in the gut. The application of multiple omics measurements to Salmonella-induced intestinal inflammation provides insights into complex molecular strategies employed during pathogenesis between host, pathogen, and the microbiome.

The synthesis of our elemental Ru NWs has been accomplished utilizing a template-based method under ambient conditions. As-prepared Ru NWs are crystalline and elementally pure, maintain electrochemical properties analogous to elemental Ru, and can be generated with average diameters ranging from 44 to 280 nm. We rationally examine the morphology-dependent performance of the Ru NWs by comparison with commercial Ru nanoparticle (NP)/carbon (C) systems after decorating the surfaces of these structures With Pt. We have demonstrated that the deposition of Pt onto the Ru NWs (Pt Ru NWs) results in a unique hierarchical structure, wherein the deposited Pt exists as discrete clusters on the surface. By contrast, we find that the Pt-decorated commercial Ru NP/C (Pt similar to Ru NP/C) results in the formation of an alloy-type NP. The Pt Ru NPs (0.61 A/mg of Pt) possess nearly 2-fold higher Pt mass activity than analogous Pt similar to Ru NW electrocatalysts (0.36 A/mg of Pt). On the basis of a long-term durability test, it is apparent that both catalysts undergo significant declines in performance, potentially resulting from aggregation and ripening in the case of Pt Ru NP/C and the effects of catalyst poisoning in the Pt similar to Ru NWs. At the conclusion of the test, both catalysts maintain comparable performance, despite a slightly enhanced performance in Pt similar to Ru NP/C. In addition, the measured mass-normalized MOR activity of the Pt similar to Ru NWs (0.36 A/mg of Pt) was significantly enhanced as compared with supported elemental Pt (Pt NP/C, 0.09 A/mg of Pt) and alloy-type PtRu (PtRu NP/C, 0.24 A/mg of Pt) NPs, both serving as commercial standards.

To the best of our knowledge, this is the first report on the use of lignin for chemical-activation-free synthesis of functional mesoporous carbon. The synthesized carbons possess the pore widths within the range of 2.5-12.0 nm. In this series of mesoporous carbons, our best result demonstrates a Brunauer-Emmett-Teller (BET) surface area of 418 m(2)/g and a mesopore volume of 0.34 cm(3)/g, which is twice the micropore volume in this carbon. Because of the dominant mesoporosity, this engineered carbon demonstrates adsorption and controlled release of a representative pharmaceutical drug, captopril, in simulated gastric fluid. Large-scale utilization of these sustainable mesoporous carbons in applications involving adsorption, transport, and controlled release of functional molecules is desired for industrial processes that yield lignin as a coproduct.

TI Contribution of atom-probe tomography to a better understanding of glass alteration mechanisms: Application to a nuclear glass specimen altered 25 years in a granitic environment SO CHEMICAL GEOLOGY LA English DT Article DE Nuclear glass; Atom probe tomography; Interdiffusion; Alteration layers; Long-term rate ID BOROSILICATE GLASSES; WASTE GLASS; WATER PENETRATION; SILICATE-GLASSES; DISSOLUTION RATE; SURFACE-LAYERS; 1ST PRINCIPLES; RICH SOLUTIONS; ION-EXCHANGE; GRAAL MODEL AB We report and discuss results of atom probe tomography (APT) and energy-filtered transmission electron microscopy (EFTEM) applied to a borosilicate glass sample of nuclear interest altered for 25.75 years at 90 degrees C in a confined granitic medium in order to better understand the rate-limiting mechanisms under conditions representative of a deep geological repository for vitrified radioactive waste. The APT technique allows the 3D reconstruction of the elemental distribution at the reactive interphase with sub-nanometer precision. Profiles of the B distribution at pristine glass/hydrated glass interface obtained by different techniques are compared to show the challenge of accurate measurements of diffusion profiles at this buried interface on the nanometer length scale. Our results show that 1) Li from the glass and hydrogen from the solution exhibit anti-correlated 15 nm wide gradients located between the pristine glass and the hydrated glass layer, and 2) boron exhibits an unexpectedly sharp profile (similar to 3 nm width) located just outside of the Li/H interdiffusion layer; this sharp profile is more consistent with a dissolution front than a diffusion-controlled release of boron. The resulting apparent diffusion coefficients derived from the Li and H profiles are D-Li = 1.5 x 10(-22) M-2.s(-1) and D-H = 6.8 x 10(-23) M-2.s(-1). These values are around two orders of magnitude lower than those observed at the very beginning of the alteration process, which suggests that interdiffusion is slowed at high reaction progress by local conditions that could be related to the porous structure of the interphase. As a result, the accessibility of water to the pristine glass could be the rate-limiting step in these conditions. More generally, these findings strongly support the importance of interdiffusion coupled with hydrolysis reactions of the silicate network on the long-term dissolution rate, contrary to what has been suggested by recent interfacial dissolution-precipitation models for silicate minerals.

We report the intermolecular,, metal-catalyzed addition of phenols to unactivated alpha-olefins. Mechanistic studies of this rare catalytic reaction revealed a dynamic mixture of resting states that undergo O-H bond oxidative addition and subsequent olefin insertion to form ether products.

Their catalytic behavior in several reactions were also examined and compared to a Bronsted acid (HOAc) and a commonly employed thiourea ((3,5-(CF3)(2)C6H3NH)(2)CS). The combination of inductive stabilization and hydrogen bonds was found to afford potent acids which are effective catalysts. It also appears that hydrogen bonds can transmit the inductive effect over distance even in an aqueous environment, and this has far reaching implications.

TI Observations of the Effect of Ionization-Potential Depression in Hot Dense Plasma SO PHYSICAL REVIEW LETTERS LA English DT Article ID LASER-SHOCKED SOLIDS; TARGETS; SPECTRA; SHIFT; EDGE AB The newly commissioned Orion laser system has been used to study dense plasmas created by a combination of short pulse laser heating and compression by laser driven shocks. Thus the plasma density was systematically varied between 1 and 10 g/cc by using aluminum samples buried in plastic foils or diamond sheets. The aluminum was heated to electron temperatures between 500 and 700 eV allowing the plasma conditions to be diagnosed by K-shell emission spectroscopy. The K-shell spectra show the effect of the ionization potential depression as a function of density. The data are compared to simulated spectra which account for the change in the ionization potential by the commonly used Stewart and Pyatt prescription and an alternative due to Ecker and Kroll suggested by recent x-ray free-electron laser experiments. The experimental data are in closer agreement with simulations using the model of Stewart and Pyatt. C1 [Hoarty, D. J.; Allan, P.; James, S. F.; Brown, C. R. D.; Hobbs, L. M. R.; Hill, M.

Unlike other bcc metals, two types of interstitial loops, 1/2 < 111 > and < 100 >, are formed in bcc iron and its alloys. However, the mechanism by which < 100 > interstitial dislocation loops are formed has remained undetermined since they were first observed more than fifty years ago. We describe our atomistic simulations that have provided the first direct observation of < 100 > loop formation. The process was initially observed using our self-evolving atomistic kinetic Monte Carlo method, and subsequently confirmed using molecular dynamics simulations. Formation of < 100 > loops involves a distinctly atomistic interaction between two 1/2 < 111 > loops, and does not follow the conventional assumption of dislocation theory, which is Burgers vector conservation between the reactants and the product. The process observed is different from all previously proposed mechanisms. Thus, our observations might provide a direct link between experiments and simulations and new insights into defect formation that may provide a basis to increase the radiation resistance of these strategic materials.

TI Drude weight of the spin-1/2 XXZ chain: Density matrix renormalization group versus exact diagonalization SO PHYSICAL REVIEW B LA English DT Article ID HEISENBERG-MODEL; TRANSPORT; INTEGRABILITY; CONDUCTIVITY; TEMPERATURES; STIFFNESS; DYNAMICS; SYSTEMS AB We revisit the problem of the spin Drude weight D of the integrable spin-1/2 XXZ chain using two complementary approaches, exact diagonalization (ED) and the time-dependent density-matrix renormalization group (tDMRG). We pursue two main goals. First, we present extensive results for the temperature dependence of D. By exploiting time translation invariance within tDMRG, one can extract D for significantly lower temperatures than in previous tDMRG studies. Second, we discuss the numerical quality of the tDMRG data and elaborate on details of the finite-size scaling of the ED results, comparing calculations carried out in the canonical and grand-canonical ensembles. Furthermore, we analyze the behavior of the Drude weight as the point with SU(2)-symmetric exchange is approached and discuss the relative contribution of the Drude weight to the sum rule as a function of temperature.

TI Sub-barrier fusion enhancement with radioactive Te-134 SO PHYSICAL REVIEW C LA English DT Article ID HEAVY-ION FUSION; NUCLEON-TRANSFER; COULOMB BARRIER; COUPLINGS; ENERGIES; FISSION; NI+SN; MODEL AB The fusion cross sections of radioactive Te-134 + Ca-40 were measured at energies above and below the Coulomb barrier. The evaporation residues produced in the reaction were detected in a zero-degree ionization chamber providing high efficiency for inverse kinematics. Both coupled-channel calculations and comparison with similar Sn + Ca systems indicate an increased sub-barrier fusion probability that is correlated with the presence of positive Q-value neutron transfer channels. In comparison, the measured fusion excitation functions of Te-130 + Ni-58,Ni-64, which have positive Q-value neutron transfer channels, were accurately reproduced by coupled-channel calculations including only inelastic excitations. The results demonstrate that the coupling of transfer channels can lead to enhanced sub-barrier fusion but this is not directly correlated with positive Q-value neutron transfer channels in all cases.

A model of Nieves et al. [Phys. Rev. C 83, 045501 (2011)] is further developed by performing exact integration and avoiding several approximations. The effect of exact integration is investigated both for double-differential and total neutrino-nucleus cross sections. The impact of nuclear effects with in-medium modifications of the Delta(1232) resonance properties as well as an effective field theory nonresonant background contribution are discussed. The dependence of the fraction of Delta(1232) decays into n-particle-n-hole states on incident neutrino energy is estimated. The impact of various ingredients of the model on the ratio of muon to electron neutrino cross sections is investigated in detail.

TI Detection of surface carbon and hydrocarbons in hot spot regions of niobium superconducting rf cavities by Raman spectroscopy SO PHYSICAL REVIEW SPECIAL TOPICS-ACCELERATORS AND BEAMS LA English DT Article ID AUGMENTED-WAVE METHOD; CRYSTAL-STRUCTURE; HYDROGEN; SYSTEMS AB Raman microscopy/spectroscopy measurements are presented on high purity niobium (Nb) samples, including pieces from hot spot regions of a tested superconducting rf cavity that exhibit a high density of etch pits. Measured spectra are compared with density functional theory calculations of Raman-active, vibrational modes of possible surface Nb-O and Nb-H complexes. The Raman spectra inside particularly rough pits in all Nb samples show clear differences from surrounding areas, exhibiting enhanced intensity and sharp peaks. While some of the sharp peaks are consistent with calculated NbH and NbH2 modes, there is better overall agreement with C-H modes in chain-type hydrocarbons. Other spectra reveal two broader peaks attributed to amorphous carbon. Niobium foils annealed to >2000 degrees C in high vacuum develop identical Raman peaks when subjected to cold working. Regions with enhanced C and O have also been found by SEM/EDX spectroscopy in the hot spot samples and cold-worked foils, corroborating the Raman results. Such regions with high concentrations of impurities are expected to suppress the local superconductivity and this may explain the correlation between hot spots in superconducting rf (SRF) cavities and the observation of a high density of surface pits. The origin of localized high carbon and hydrocarbon regions is unclear at present but it is suggested that particular processing steps in SRF cavity fabrication may be responsible.

Paul TI Hexameric Octahedral Clusters of PbSe Nanocrystals Grown from Amorphous Lead(II) Carboxylate Nanoparticles SO CHEMISTRY OF MATERIALS LA English DT Article DE nanocrystal synthesis; lead selenide; oriented attachment; electron tomography ID ORIENTED ATTACHMENT; ELECTRON-MICROSCOPY AB We describe the synthesis and three-dimensional structure of a new single-crystalline "hexameric" nanocrystal composed of six near-spherical PbSe nanocrystals arranged at the vertices of an octahedron. We examine the detailed three-dimensional structure of these nanocrystals using electron tomography and demonstrate single-crystal to single-crystal cation exchange to CdSe. We reveal that the growth of these nanocrystals, which form under conditions similar to other anisotropic PbSe nanocrystals, depends on the initial presence of lead oleate particles with approximate diameters of 1.7-3.1 nm that form upon heating lead(II) acetate hydrate in the presence of oleic acid. These lead oleate particles, which are visible by transmission electron microscopy, constitute the beginning of nearly every synthesis of anisotropic PbSe nanocrystals. We show that the lead oleate particles play a definitive role in determining the morphology of the resultant PbSe nanocrystals. We note that the acetate anion, which was previously identified as the key factor in achieving anisotropic PbSe growth, greatly accelerates the formation of the lead oleate particles, and thus appears to be responsible for the subsequent PbSe morphology. However, we demonstrate that acetate is not required for lead oleate particle formation, nor indeed for anisotropic PbSe growth. The potential role of these new particles in other PbSe synthetic preparations from lead(II) oleate is of high interest for future study.

CA ALICE Collaboration TI Charge correlations using the balance function in Pb-Pb collisions at root s(NN)=2.76 TeV SO PHYSICS LETTERS B LA English DT Article DE Balance function; Charge correlations; ALICE LHC ID HEAVY-ION COLLISIONS; QUARK-GLUON PLASMA; NUCLEAR COLLISIONS; THERMAL-MODEL; PARTICLE-PRODUCTION; COALESCENCE MODEL; COLLABORATION; PERSPECTIVE; RESONANCES; PARTON AB In high-energy heavy-ion collisions, the correlations between the emitted particles can be used as a probe to gain insight into the charge creation mechanisms. In this Letter, we report the first results of such studies using the electric charge balance function in the relative pseudorapidity (Delta eta) and azimuthal angle (Delta phi) in Pb-Pb collisions at root s(NN) = 2.76 TeV with the ALICE detector at the Large Hadron Collider. The width of the balance function decreases with growing centrality (i.e. for more central collisions) in both projections. This centrality dependence is not reproduced by HIJING, while AMPT, a model which incorporates strings and parton rescattering, exhibits qualitative agreement with the measured correlations in Delta phi but fails to describe the correlations in Delta eta. A thermal blast-wave model incorporating local charge conservation and tuned to describe the p(T) spectra and v(2) measurements reported by ALICE, is used to fit the centrality dependence of the width of the balance function and to extract the average separation of balancing charges at freeze-out. The comparison of our results with measurements at lower energies reveals an ordering with root s(NN): the balance functions become narrower with increasing energy for all centralities. This is consistent with the effect of larger radial flow at the LHC energies but also with the late stage creation scenario of balancing charges. However, the relative decrease of the balance function widths in Delta eta and Delta phi, with centrality from the highest SPS to the LHC energy exhibits only small differences. This observation cannot be interpreted solely within the framework where the majority of the charge is produced at a later stage in the evolution of the heavy-ion collision. (C) 2013 CERN.

CA CMS Collaboration TI Search for heavy resonances in the W/Z-tagged dijet mass spectrum in pp collisions at 7 TeV SO PHYSICS LETTERS B LA English DT Article DE CMS; Physics; Dijet; Jet substructure; Resonances ID ROOT-S=7 TEV; Z BOSONS; PHENOMENOLOGY; PHYSICS; LEPTON AB A search has been made for massive resonances decaying into a quark and a vector boson, qW or qZ, or a pair of vector bosons, WW, WZ, or ZZ, where each vector boson decays to hadronic final states. This search is based on a data sample corresponding to an integrated luminosity of 5.0 fb(-1) of proton-proton collisions collected in the CMS experiment at the LHC in 2011 at a center-of-mass energy of 7 TeV. For sufficiently heavy resonances the decay products of each vector boson are merged into a single jet, and the event effectively has a dijet topology. The background from QCD dijet events is reduced using recently developed techniques that resolve jet substructure. A 95% CL lower limit is set on the mass of excited quark resonances decaying into qW (qZ) at 2.38 TeV (2.15 TeV) and upper limits are set on the cross section for resonances decaying to qW, qZ, WW, WZ, or ZZ final states.

With the leading term in the 2-particle-irreducible formalism the resultant effective potential exhibits a first-order phase transitions for the pure SU(3) Yang-Mills theory at the critical temperature consistent with the empirical value. We also estimate the thermodynamic quantities to confirm qualitative agreement with the lattice data near the critical temperature. We then apply our effective potential to the chiral model-study and calculate the order parameters and the thermodynamic quantities. Unlike the case in the pure Yang-Mills theory the thermodynamic quantities are sensitive to the temperature dependence of the non-perturbative propagators, while the behavior of the order parameters is less sensitive, which implies the importance of the precise determination of the temperature-dependent propagators.

TI Oxidation of nanoscale Au-In alloy particles as a possible route toward stable Au-based catalysts SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE transmission electron microscopy; temperature programmed desorption; X-ray photoelectron spectroscopy ID AMINE N-OXIDES; LOW-TEMPERATURE; CO OXIDATION; ROOM-TEMPERATURE; NANOPARTICLES; GOLD; KINETICS; ADSORPTION; OXYGEN; INTERDIFFUSION AB The oxidation of bimetallic alloy nanoparticles comprising a noble and a nonnoble metal is expected to cause the formation of a single-component surface oxide of the nonnoble metal, surrounding a core enriched with the noble metal. Studying the room temperature oxidation of Au-In nanoparticles, we show that this simple picture does not apply to an important class of bimetallic alloys, in which the oxidation proceeds via predominant oxygen diffusion. Instead of a crystalline In2O3 shell, such oxidation leads to an amorphous shell of mixed Au-In oxide that remains stable to high temperatures and whose surface layer is enriched with Au. The Au-rich mixed oxide is capable of adsorbing both CO and O-2 and converting them to CO2, which desorbs near room temperature. The oxidation of Au-In alloys to a mixed Au-In oxide shows significant promise as a viable approach toward Au-based oxidation catalysts, which do not require any complex synthesis processes and resist deactivation up to at least 300 degrees C.

TI Neutron diffraction observations of interstitial protons in dense ice SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE crystallography; high pressure; water ID HYDROGEN-BOND SYMMETRIZATION; X-RAY-DIFFRACTION; HIGH-PRESSURE; DISORDERED STRUCTURE; INFRARED-ABSORPTION; RAMAN-SPECTROSCOPY; POWDER DIFFRACTION; GPA; VII; PHASE AB The motif of distinct H2O molecules in H-bonded networks is believed to persist up to the densest molecular phase of ice. At even higher pressures, where the molecule dissociates, it is generally assumed that the proton remains localized within these same networks. We report neutron-diffraction measurements on D2O that reveal the location of the D atoms directly up to 52 GPa, a pressure regime not previously accessible to this technique. The data show the onset of a structural change at similar to 13 GPa and cannot be described by the conventional network structure of ice VII above similar to 26 GPa. Our measurements are consistent with substantial deuteron density in the octahedral, interstitial voids of the oxygen lattice. The observation of this "interstitial" ice VII form provides a framework for understanding the evolution of hydrogen bonding in ice that contrasts with the conventional picture. It may also be a precursor for the superionic phase reported at even higher pressure with important consequences for our understanding of dense matter and planetary interiors.

TI Ptr-miR397a is a negative regulator of laccase genes affecting lignin content in Populus trichocarpa SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article ID STRESS-RESPONSIVE MICRORNAS; MOLECULAR-CLONING; DOWN-REGULATION; COPPER; BIOSYNTHESIS; ARABIDOPSIS; PEROXIDASE; EXPRESSION; PLANTS; IDENTIFICATION AB Laccases, as early as 1959, were proposed to catalyze the oxidative polymerization of monolignols. Genetic evidence in support of this hypothesis has been elusive due to functional redundancy of laccase genes. An Arabidopsis double mutant demonstrated the involvement of laccases in lignin biosynthesis. We previously identified a subset of laccase genes to be targets of a microRNA (miRNA) ptr-miR397a in Populus trichocarpa. To elucidate the roles of ptr-miR397a and its targets, we characterized the laccase gene family and identified 49 laccase gene models, of which 29 were predicted to be targets of ptr-miR397a. We overexpressed Ptr-MIR397a in transgenic P. trichocarpa. In each of all nine transgenic lines tested, 17 PtrLACs were down-regulated as analyzed by RNA-seq. Transgenic lines with severe reduction in the expression of these laccase genes resulted in an similar to 40% decrease in the total laccase activity. Overexpression of Ptr-MIR397a in these transgenic lines also reduced lignin content, whereas levels of all monolignol biosynthetic gene transcripts remained unchanged. A hierarchical genetic regulatory network(GRN) built by a bottom-up graphic Gaussian model algorithm provides additional support for a role of ptr-miR397a as a negative regulator of laccases for lignin biosynthesis. Full transcriptome-based differential gene expression in the overexpressed transgenics and protein domain analyses implicate previously unidentified transcription factors and their targets in an extended hierarchical GRN including ptr-miR397a and laccases that coregulate lignin biosynthesis in wood formation. Ptr-miR397a, laccases, and other regulatory components of this network may provide additional strategies for genetic manipulation of lignin content.

TI Genome Analysis and Physiological Comparison of Alicycliphilus denitrificans Strains BC and K601(T) SO PLOS ONE LA English DT Article ID PERIPLASMIC NITRATE REDUCTASE; ANAEROBIC BENZENE DEGRADATION; CYTOCHROME-C-OXIDASE; AROMATIC-COMPOUNDS; PERCHLORATE REDUCTION; CHLORITE DISMUTASE; REDUCING BACTERIA; RNA GENES; 1ST STEP; METABOLISM AB The genomes of the Betaproteobacteria Alicycliphilus denitrificans strains BC and K601(T) have been sequenced to get insight into the physiology of the two strains. Strain BC degrades benzene with chlorate as electron acceptor. The cyclohexanol-degrading denitrifying strain K601(T) is not able to use chlorate as electron acceptor, while strain BC cannot degrade cyclohexanol. The 16S rRNA sequences of strains BC and K601(T) are identical and the fatty acid methyl ester patterns of the strains are similar. Basic Local Alignment Search Tool (BLAST) analysis of predicted open reading frames of both strains showed most hits with Acidovorax sp. JS42, a bacterium that degrades nitro-aromatics. The genomes include strain-specific plasmids (pAlide201 in strain K601(T) and pAlide01 and pAlide02 in strain BC). Key genes of chlorate reduction in strain BC were located on a 120 kb megaplasmid (pAlide01), which was absent in strain K601(T). Genes involved in cyclohexanol degradation were only found in strain K601(T). Benzene and toluene are degraded via oxygenase-mediated pathways in both strains. Genes involved in the meta-cleavage pathway of catechol are present in the genomes of both strains. Strain BC also contains all genes of the ortho-cleavage pathway. The large number of mono-and dioxygenase genes in the genomes suggests that the two strains have a broader substrate range than known thus far.

Members of the E1 and E3 enzyme families can undergo particularly large conformational changes during their catalytic cycles, involving the remodeling of domain interfaces. This enables the efficient, directed and regulated handover of ubiquitin from one carrier to the next one. We review some of these conformational transformations, as revealed by crystallographic studies.

TI Nontrivial spin texture of the coaxial Dirac cones on the surface of topological crystalline insulator SnTe SO PHYSICAL REVIEW B LA English DT Article ID TRANSITION; PHASE AB We present first-principles calculations of the nontrivial surface states and their spin textures in the topological crystalline insulator SnTe. The surface state dispersion on the [001] surface exhibits four Dirac cones centered along the intersection of the mirror plane and the surface plane. We propose a simple model of two interacting coaxial Dirac cones to describe both the surface state dispersion and the associated spin texture. The out-of-plane spin polarization is found to be zero due to the crystalline and time-reversal symmetries. The in-plane spin texture shows helicity with some distortion due to the interaction of the two coaxial Dirac cones, indicating a nontrivial mirror Chern number of -2, distinct from the value of -1 in a Z(2) topological insulator such as Bi/Sb alloys or Bi2Se3. The surface state dispersion and its spin texture would provide an experimentally accessible signature for determining the nontrivial mirror Chern number.

TI Bifurcated Structure of the Electron Diffusion Region in Three-Dimensional Magnetic Reconnection SO PHYSICAL REVIEW LETTERS LA English DT Article ID SOLAR CORONA; FIELD LINES; INSTABILITIES; MAGNETOPAUSE; SIMULATIONS; PLASMA; SHEAR AB Three-dimensional kinetic simulations of magnetic reconnection reveal that the electron diffusion region is composed of two or more current sheets in regimes with weak magnetic shear angles phi less than or similar to 80 degrees. This new morphology is explained by oblique tearing modes which produce flux ropes while simultaneously driving enhanced current at multiple resonance surfaces. This physics persists into the nonlinear regime leading to multiple electron layers embedded within a larger Alfvenic inflow and outflow. Surprisingly, the thickness of these layers and the reconnection rate both remain comparable to two-dimensional models. The parallel electric fields are supported predominantly by the electron pressure tensor and electron inertia, while turbulent dissipation remains small.

It exhibits clear duality in characteristics, being both destructive and beneficial in our daily lives and industrial processes. Despite the multitude of occurrences of this phenomenon, highly dynamic and multiphase cavitating flows have not been fundamentally well understood in guiding the effort to harness the transient and localized power generated by this process. In a microscale, multiphase flow liquid injection system, we synergistically combined experiments using time-resolved x-radiography and a novel simulation method to reveal the relationship between the injector geometry and the in-nozzle cavitation quantitatively. We demonstrate that a slight alteration of the geometry on the micrometer scale can induce distinct laminar-like or cavitating flows, validating the multiphase computational fluid dynamics simulation. Furthermore, the simulation identifies a critical geometric parameter with which the high-speed flow undergoes an intriguing transition from non-cavitating to cavitating.

We propose a mitigation approach in which the dynamical effect of the longitudinal component of CSR is suppressed by appropriately preparing the initial longitudinal current profile of the beam. In a chicane, a linear theory for the mechanism of CSR-induced emittance growth is used to demonstrate how this procedure can produce a beam whose core experiences suppressed transverse emittance growth. The dynamics of such a beam is illustrated for the Berlin-Zeuthen CSR benchmark chicane.

In these assays, the targeted tumor cell populations are first labeled with fluorescent Cell Tracker dyes and immobilized using a DNA-based adhesion technique. This allows the facile generation of live cell arrays that are arranged arbitrarily or in ordered rectilinear patterns. Following the addition of antibodies in combination with serum, PBMCs, or whole blood, cell death within the targeted population can be assessed by the addition of propidium iodide (PI) as a viability probe. The array is then analyzed with an automated microscopic imager. The extent of cytotoxicity can be quantified accurately by comparing the number of surviving target cells to the number of dead cells labeled with both Cell Tracker and PI. Excellent batch-to-batch reproducibility has been achieved using this method. In addition to allowing cytotoxicity analysis to be conducted in real time on a single cell basis, this new assay overcomes the need for hazardous radiochemicals. Fluorescently-labeled antibodies can be used to identify individual cells that bear the targeted receptors, but yet resist the CDC and ADCC mechanisms. This new approach also allows the use of whole blood in cytotoxicity assays, providing an assessment of antibody efficacy in a highly relevant biological mixture. Given the rapid development of new antibody-based therapeutic agents, this convenient assay platform is well-poised to streamline the drug discovery process significantly.

TI Electrical conduction channel along the grain boundaries of Cu(In,Ga)Se-2 thin films SO APPLIED PHYSICS LETTERS LA English DT Article ID SPREADING RESISTANCE MICROSCOPY; SOLAR-CELLS; SILICON AB We report on a direct nm-resolution resistance mapping on the Cu(In,Ga)Se-2 photovoltaic thin films, using scanning spreading resistance microcopy. We found a conductance channel along the grain boundaries (GBs) of the polycrystalline materials, which is consistent with the argument that carrier polarity of the GB and the space charge region around it is inverted. To minimize the probe/film contact resistance, so that the local spreading resistance beneath the probe is measured, the probe must be adequately indented to the film and a bias voltage larger than the onset value of the probe/film barrier should be applied.

TI Investigation of ripple-limited low-field mobility in large-scale graphene nanoribbons SO APPLIED PHYSICS LETTERS LA English DT Article ID TRANSISTORS; TRANSPORT; SIO2 AB Combining molecular dynamics and quantum transport simulations, we study the degradation of mobility in graphene nanoribbons caused by substrate-induced ripples. First, the atom coordinates of large-scale structures are relaxed such that surface properties are consistent with those of graphene on a substrate. Then, the electron current and low-field mobility of the resulting non-flat nanoribbons are calculated within the Non-equilibrium Green's Function formalism in the coherent transport limit. An accurate tight-binding basis coupling the sigma- and pi-bands of graphene is used for this purpose. It is found that the presence of ripples decreases the mobility of graphene nanoribbons on SiO2 below 3000 cm(2)/Vs, which is comparable to experimentally reported values.

The interaction region of the out-of-plane strain, epsilon(33), from a TSV feature containing copper metallization extended approximately 6 mu m from the TSV outer edge for circular and annular geometries. Measurements conducted on identical TSV structures without copper reveal that strain fields generated by the liner materials extend a similar distance and with comparable magnitude as those with copper. FEM-based simulations show the total interaction region induced by the TSV can extend farther than that of epsilon(33). (C) 2013 AIP Publishing LLC.

We reveal that the residual resistance decreases with field at B-rf <= 40mT and strongly increases in chemically treated niobium at B-rf > 80 mT. We find that BCS surface resistance is weakly dependent on field in the clean limit, whereas a strong and peculiar field dependence emerges after 120 degrees C vacuum baking.

TI Nanoclusters of MoO3-x embedded in an Al2O3 matrix engineered for customizable mesoscale resistivity and high dielectric strength SO APPLIED PHYSICS LETTERS LA English DT Article ID LAYER DEPOSITION TECHNIQUES; GROWTH AB We have synthesized a material consisting of conducting metal oxide (MoO3-x) nanoclusters embedded in a high-dielectric-strength insulator (Al2O3) matrix. The resistivity of this material can be customized by varying the concentration of the MoO3-x nanoclusters. The Al2O3 protects the MoO3-x from stoichiometry change, thus conserving the number of carriers and maintaining a high dielectric strength. This composite material is grown by atomic layer deposition, a thin film deposition technique suitable for coating 3D structures. We applied these atomic layer deposition composite films to our 3D electron-optical micro electrical mechanical systems devices and greatly improved their performance. (C) 2013 AIP Publishing LLC.

It contains vorticity terms and a four-dimensional Euclidean Berry monopole which gives an axial anomaly. By integrating out the zeroth component of the 4-momentum p, we reproduce the previous three-dimensional results derived from the Hamiltonian approach, together with the newly derived vorticity terms. The phase space continuity equation has an anomalous source term proportional to the product of electric and magnetic fields (F-sigma rho(F) over tilde (sigma rho)similar to E sigma B sigma). This provides a unified interpretation of the chiral magnetic and vortical effects, chiral anomaly, Berry curvature, and the Berry monopole in the framework of Wigner functions.

We show that gradient-driven vortices interacting with a conformal pinning array exhibit substantially stronger pinning effects over a much larger range of field than found for random or periodic pinning arrangements. The pinning enhancement is partially due to matching of the critical flux gradient with the pinning gradient, but the preservation of local ordering in the conformally transformed hexagonal lattice and the arching arrangement of the pinning also play crucial roles. Our results can be generalized to a wide class of gradient-driven interacting particle systems such as colloids on optical trap arrays.

TI Reactivity of Xenon with Ice at Planetary Conditions SO PHYSICAL REVIEW LETTERS LA English DT Article ID GIANT PLANETS; NOBLE; VOLATILES; MOLECULES AB We report results from high pressure and temperature experiments that provide evidence for the reactivity of xenon with water ice at pressures above 50 GPa and a temperature of 1500 K-conditions that are found in the interiors of Uranus and Neptune. The x-ray data are sufficient to determine a hexagonal lattice with four Xe atoms per unit cell and several possible distributions of O atoms. The measurements are supplemented with ab initio calculations, on the basis of which a crystallographic structure with a Xe4O12H12 primitive cell is proposed. The newly discovered compound is formed in the stability fields of superionic ice and eta-O-2, and has the same oxygen subnetwork as the latter. Furthermore, it has a weakly metallic character and likely undergoes sublattice melting of the H subsystem. Our findings indicate that Xe is expected to be depleted in the atmospheres of the giant planets as a result of sequestration at depth.

Santo TI Functional microbial diversity explains groundwater chemistry in a pristine aquifer SO BMC MICROBIOLOGY LA English DT Article ID ANAEROBIC METHANE OXIDATION; SULFATE REDUCTION; MULTIVARIATE ANALYSES; REDUCING BACTERIA; CRETACEOUS ROCK; BEDROCK VALLEY; SUBSURFACE; SEDIMENTS; SEQUENCE; SYSTEMS AB Background: The diverse microbial populations that inhabit pristine aquifers are known to catalyze critical in situ biogeochemical reactions, yet little is known about how the structure and diversity of this subsurface community correlates with and impacts upon groundwater chemistry. Herein we examine 8,786 bacterial and 8,166 archaeal 16S rRNA gene sequences from an array of monitoring wells in the Mahomet aquifer of east-central Illinois. Using multivariate statistical analyses we provide a comparative analysis of the relationship between groundwater chemistry and the microbial communities attached to aquifer sediment along with those suspended in groundwater. Results: Statistical analyses of 16S rRNA gene sequences showed a clear distinction between attached and suspended communities; with iron-reducing bacteria far more abundant in attached samples than suspended, while archaeal clones related to groups associated with anaerobic methane oxidation and deep subsurface gold mines (ANME-2D and SAGMEG-1, respectively) distinguished the suspended community from the attached. Within the attached bacterial community, cloned sequences most closely related to the sulfate-reducing Desulfobacter and Desulfobulbus genera represented 20% of the bacterial community in wells where the concentration of sulfate in groundwater was high (> 0.2 mM), compared to only 3% in wells with less sulfate. Sequences related to the genus Geobacter, a genus containing ferric-iron reducers, were of nearly equal abundance (15%) to the sulfate reducers under high sulfate conditions, however their relative abundance increased to 34% when sulfate concentrations were < 0.03 mM. Also, in areas where sulfate concentrations were < 0.03 mM, archaeal 16S rRNA gene sequences similar to those found in methanogens such as Methanosarcina and Methanosaeta comprised 73-80% of the community, and dissolved CH4 ranged between 220 and 1240 mu M in these groundwaters. In contrast, methanogens (and their product, CH4) were nearly absent in samples collected from groundwater samples with > 0.2 mM sulfate. In the suspended fraction of wells where the concentration of sulfate was between 0.03 and 0.2 mM, the archaeal community was dominated by sequences most closely related to the ANME-2D, a group of archaea known for anaerobically oxidizing methane. Based on available energy (Delta G(A)) estimations, results varied little for both sulfate reduction and methanogenesis throughout all wells studied, but could favor anaerobic oxidation of methane (AOM) in wells containing minimal sulfate and dihydrogen, suggesting AOM coupled with H-2-oxidizing organisms such as sulfate or iron reducers could be an important pathway occurring in the Mahomet aquifer. Conclusions: Overall, the results show several distinct factors control the composition of microbial communities in the Mahomet aquifer. Bacteria that respire insoluble substrates such as iron oxides, i.e. Geobacter, comprise a greater abundance of the attached community than the suspended regardless of groundwater chemistry. Differences in community structure driven by the concentration of sulfate point to a clear link between the availability of substrate and the abundance of certain functional groups, particularly iron reducers, sulfate reducers, methanogens, and methanotrophs. Integrating both geochemical and microbiological observations suggest that the relationships between these functional groups could be driven in part by mutualism, especially between ferric-iron and sulfate reducers.

Hughes, Richard J. TI Security of decoy-state protocols for general photon-number-splitting attacks SO PHYSICAL REVIEW A LA English DT Article ID QUANTUM KEY DISTRIBUTION AB Decoy-state protocols provide a way to defeat photon-number-splitting attacks in quantum cryptography implemented with weak coherent pulses. We point out that previous security analyses of such protocols relied on assumptions about eavesdropping attacks that considered treating each pulse equally and independently. We give an example to demonstrate that, without such assumptions, the security parameters of previous decoy-state implementations could be worse than the ones claimed. Next we consider more general photon-number-splitting attacks, which correlate different pulses, and give an estimation procedure for the number of single-photon signals with rigorous security statements. The impact of our result is that previous analyses of the number of times a decoy-state quantum cryptographic system can be reused before it makes a weak key must be revised.

TI Proximity-induced unconventional superconductivity in topological insulators SO PHYSICAL REVIEW B LA English DT Article ID SURFACE; TRANSPORT; BI2SE3; BI2TE3 AB We study and classify the proximity-induced superconducting pairing in a topological insulator (TI)-superconductor (SC) hybrid structure for SCs with different symmetries. The Dirac surface state gives a coupling between spin-singlet and spin-triplet pairing amplitudes as well as pairing that is odd in frequency for p-wave SCs. We also find that all SCs induce pairing that is odd in both frequency and orbital (band) index, with oddness in frequency and orbital index being completely interchangeable. The different induced pairing amplitudes significantly modify the density of states in the TI surface layer. C1 [Black-Schaffer, Annica M.] Uppsala Univ, Dept Phys & Astron, S-75120 Uppsala, Sweden.

TI Silicon spin chains at finite temperature: Dynamics of Si(553)-Au SO PHYSICAL REVIEW B LA English DT Article ID AUGMENTED-WAVE METHOD; AB-INITIO; ONE-DIMENSION; WIRES; RECONSTRUCTION; MODELS AB When gold is deposited on Si(553), the surface self-assembles to form a periodic array of steps with nearly perfect structural order. In scanning tunneling microscopy these steps resemble quasi-one-dimensional atomic chains. At temperatures below similar to 50 K the chains develop a tripled periodicity. We recently predicted, on the basis of density-functional theory calculations at T = 0, that this tripled periodicity arises from the complete polarization of the electron spin on every third silicon atom along the step; in the ground state these linear chains of silicon spins are antiferromagnetically ordered. Here we explore, using ab initio molecular dynamics and kinetic Monte Carlo simulations, the behavior of silicon spin chains on Si(553)-Au at finite temperature. Thermodynamic phase transitions at T > 0 in one-dimensional systems are prohibited by the Mermin-Wagner theorem. Nevertheless we find that a surprisingly sharp onset occurs upon cooling-at about 30 K for perfect surfaces and at higher temperature for surfaces with defects-to a well-ordered phase with tripled periodicity, in good agreement with experiment.

Perez, Danny TI Scalable kernel polynomial method for calculating transition rates SO PHYSICAL REVIEW B LA English DT Article ID CHEMICAL-REACTIONS; DENSITIES; MOMENTS; STATES AB We present an efficient method for calculating the prefactors of harmonic transition state theory rates. We reformulate the prefactors in terms of the density of states (DOS) of the Hessian matrices at the basin minimum and the saddle point. The DOS is then approximated using the kernel polynomial method as an expansion in terms of Chebyshev polynomials. The cost of the calculation scales linearly with the number of atoms, in contrast with the cubic scaling of the direct method. This approach hence greatly facilitates the investigations of kinetic processes in very large systems. We demonstrate the method by calculating the prefactors of the transition rates for two processes in bulk silver: vacancy hopping and Frenkel pair formation.

For temperatures above similar to 180 K, the spin and charge properties show an activated behavior suggestive of a narrow-gap semiconductor. At lower temperatures, the results indicate an insulating ground state which may or may not be charge ordered. While the frustrated spins in remaining patches of the original kagome lattice might not be directly detected here, the observation of coexisting nonmagnetic sites, free spins, and frozen moments reveals an intrinsically inhomogeneous magnetism. Numerical simulations of a 1/3-diluted kagome lattice rationalize this magnetic state in terms of a heterogeneous distribution of cluster sizes and morphologies near the site-percolation threshold.

We include all unfolded diagrams that are first and second order in the interaction and all singly folded diagrams that can be constructed from them.

TI Anomalous lattice expansion in yttria stabilized zirconia under simultaneous applied electric and thermal fields: A time-resolved in situ energy dispersive x-ray diffractometry study with an ultrahigh energy synchrotron probe SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID SINTERING CRYSTALLINE SOLIDS; GRAIN-GROWTH; NANOGRAIN ZIRCONIA; DIFFUSION; FERROELECTRICS; CONDUCTIVITY; DIMENSIONS; SIMULATION; KINETICS; STRESSES AB Nonisothermal densification in 8% yttria doped zirconia (8YSZ) particulate matter of 250 nm median particle size was studied under 215 V/cm dc electric field and 9 degrees C/min heating rate, using time-resolved in-situ high temperature energy dispersive x-ray diffractometry with a polychromatic 200 keV synchrotron probe. Densification occurred in the 876-905 degrees C range, which resulted in 97% of the theoretical density. No local melting at particle-particle contacts was observed in scanning electron micrographs, implying densification was due to solid state mass transport processes. The maximum current draw at 905 degrees C was 3 A, corresponding to instantaneous absorbed power density of 570 W/cm(3). Densification of 8YSZ was accompanied by anomalous elastic volume expansions of the unit cell by 0.45% and 2.80% at 847 degrees C and 905 degrees C, respectively. The anomalous expansion at 905 degrees C at which maximum densification was observed is characterized by three stages: (I) linear stage, (II) anomalous stage, and (III) anelastic recovery stage. The densification in stage I (184 s) and II (15 s) was completed in 199 s, while anelastic relaxation in stage III lasted 130 s. The residual strains (epsilon) at room temperature, as computed from tetragonal (112) and (211) reflections, are epsilon((112)) = 0.05% and epsilon((211)) = 0.13%, respectively. Time dependence of (211) and (112) peak widths (beta) show a decrease with both exhibiting a singularity at 905 degrees C. An anisotropy in (112) and (211) peak widths of {beta((112))/beta((211))} = (3:1) magnitude was observed. No phase transformation occurred at 905 degrees C as verified from diffraction spectra on both sides of the singularity, i.e., the unit cell symmetry remains tetragonal. We attribute the reduction in densification temperature and time to ultrafast ambipolar diffusion of species arising from the superposition of mass fluxes due to Fickian diffusion, thermodiffusion (Soret effect), and electromigration, which in turn are a consequence of a superposition of chemical, temperature, and electrical potential gradients. On the other hand, we propose defect pile-up at particle-particle contacts and subsequent tunneling as a mechanism creating the "burst-mode" discontinuous densification at the singularities observed at 847 and 905 degrees C.

Different thin film morphology, crystallinity, and stoichiometry have been observed depending on growth parameters. To understand the microscopic origin, the adatom nucleation, step advance processes, and their relationship to film growth were theoretically analyzed and a growth diagram was constructed. Three boundaries between highly and poorly crystallized growth, 2D and 3D growth, stoichiometric and non-stoichiometric growth were identified in the growth diagram. A good fit of our experimental observation with the growth diagram was found. This case study demonstrates that a more comprehensive understanding of the growth mode in PLD is possible.

TI Hot-spot contributions in shocked high explosives from mesoscale ignition models SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID INITIATION; COLLAPSE AB High explosive performance and sensitivity is strongly related to the mesoscale defect densities. Bracketing the population of mesoscale hot spots that are active in the shocked ignition of explosives is important for the development of predictive reactive flow models. By coupling a multiphysics-capable hydrodynamics code (ALE3D) with a chemical kinetics solver (CHEETAH), we can parametrically analyze different pore sizes undergoing collapse in high pressure shock conditions with evolving physical parameter fields. Implementing first-principles based decomposition kinetics, burning hot spots are monitored, and the regimes of pore sizes that contribute significantly to burnt mass faction and those that survive thermal conduction on the time scales of ignition are elucidated. Comparisons are drawn between the thermal explosion theory and the multiphysics models for the determination of nominal pore sizes that burn significantly during ignition for the explosive 1,3,5-triamino-2,4,6-trinitrobenzene.

TI Fusion of Dioxygenase and Lignin-binding Domains in a Novel Secreted Enzyme from Cellulolytic Streptomyces sp SirexAA-E SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID RHODOCOCCUS-OPACUS 1CP; X-RAY-SCATTERING; PROTOCATECHUATE 3,4-DIOXYGENASE; CRYSTAL-STRUCTURE; BREVIBACTERIUM-FUSCUM; KEY ENZYME; CELL-WALL; 1,2-DIOXYGENASE; CRYSTALLOGRAPHY; BIOSYNTHESIS AB Streptomyces sp. SirexAA-E is a highly cellulolytic bacterium isolated from an insect/microbe symbiotic community. When grown on lignin-containing biomass, it secretes SACTE_2871, an aromatic ring dioxygenase domain fused to a family 5/12 carbohydrate-binding module (CBM 5/12). Here we present structural and catalytic studies of this novel fusion enzyme, thus providing insight into its function. The dioxygenase domain has the core beta-sandwich fold typical of this enzyme family but lacks a dimerization domain observed in other intradiol dioxygenases. Consequently, the x-ray structure shows that the enzyme is monomeric and the Fe(III)-containing active site is exposed to solvent in a shallow depression on a planar surface. Purified SACTE_2871 catalyzes the O-2-dependent intradiol cleavage of catechyl compounds from lignin biosynthetic pathways, but not their methylated derivatives. Binding studies show that SACTE_2871 binds synthetic lignin polymers and chitin through the interactions of the CBM 5/12 domain, representing a new binding specificity for this fold-family. Based on its unique structural features and functional properties, we propose that SACTE_2871 contributes to the invasive nature of the insect/microbial community by destroying precursors needed by the plant for de novo lignin biosynthesis as part of its natural wounding response.

Budker, Dmitry Pines, Alexander TI Parahydrogen-induced polarization at zero magnetic field SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID PARA-HYDROGEN; SPIN SYSTEMS; NMR; RESONANCE; MAGNETOMETRY; STATES; ORDER AB We use symmetry arguments and simple model systems to describe the conversion of the singlet state of parahydrogen into an oscillating sample magnetization at zero magnetic field. During an initial period of free evolution governed by the scalar-coupling Hamiltonian H-J, the singlet state is converted into scalar spin order involving spins throughout the molecule. A short dc pulse along the z axis rotates the transverse spin components of nuclear species I and S through different angles, converting a portion of the scalar order into vector order. The development of vector order can be described analytically by means of single-transition operators, and it is found to be maximal when the transverse components of I are rotated by an angle of +/-pi/2 relative to those of S. A period of free evolution follows the pulse, during which the vector order evolves as a set of oscillating coherences. The imaginary parts of the coherences represent spin order that is not directly detectable, while the real parts can be identified with oscillations in the z component of the molecular spin dipole. The dipole oscillations are due to a periodic exchange between I-z and S-z, which have different gyromagnetic ratios. The frequency components of the resulting spectrum are imaginary, since the pulse cannot directly induce magnetization in the sample; it is only during the evolution under H-J that the vector order present at the end of the pulse evolves into detectable magnetization.

As an experiment to be performed at the Intensity Frontier, taking advantage of high-intensity proton beams, the Mu2e experimental setup will be residing in a harsh radiation environment created by secondary particle fluxes. Radiation quantities in different parts of the Mu2e apparatus, such as neutron flux, peak power density, displacements per atom (DPA), absorbed dose, dynamic heat load simulated using the MARS15 code are reviewed in this work. Radiation levels and requirements for Heat and Radiation Shield (HRS), Transport Solenoid (TS), residual dose and decay heat from the Mu2e target, beam dump design, rates in Cosmic Ray Veto (CRV) counters as well as stopping target monitor (STM) are considered. Airflow, surface and ground water activation are estimated. Recent developments in the MARS15 DPA model applied in this work are described, their consequences are discussed.

TI Field dependence of the spin state and spectroscopic modes of multiferroic BiFeO3 SO PHYSICAL REVIEW B LA English DT Article AB The spectroscopic modes of multiferroic BiFeO3 provide detailed information about the very small anisotropy and Dzyaloshinskii-Moriya (DM) interactions responsible for the long-wavelength, distorted cycloid below T-N = 640 K. A microscopic model that includes two DM interactions and easy-axis anisotropy predicts both the zero-field spectroscopic modes as well as their splitting and evolution in a magnetic field applied along a cubic axis. While only six modes are optically active in zero field, all modes at the cycloidal wave vector are activated by a magnetic field. The three magnetic domains of the cycloid are degenerate in zero field but one domain has lower energy than the other two in nonzero field. Measurements imply that the higher-energy domains are depopulated above about 6 T and have a maximum critical field of 16 T, below the critical field of 19 T for the lowest-energy domain. Despite the excellent agreement with the measured spectroscopic frequencies, some discrepancies with the measured spectroscopic intensities suggest that other weak interactions may be missing from the model.

Kaminski, Adam TI Angle-resolved photoemission spectroscopy study of BaCo2As2 SO PHYSICAL REVIEW B LA English DT Article ID 43 K; SUPERCONDUCTIVITY; LAO1-XFXFEAS; TRANSITION AB We use angle-resolved photoemission spectroscopy and full-potential linearized augmented-plane-wave (FP-LAPW) calculations to study the electronic structure of BaCo2As2. The Fermi surface (FS) maps and the corresponding band dispersion data (at 90 and 200 K) reveal a small electron pocket at the center and a large electron pocket at the corner of the Brillouin zone. Therefore the nesting between electron and hole FS pockets is absent in this compound, in contrast to the parent compounds of FeAs-based high-T-c superconductors. The electron pockets at the center of the zone are surrounded by two sets of four smaller electron pockets. The electronic structure at about 500 meV binding energy is very similar to features at the chemical potential in BaFe2As2. This indicates that complete substitution of Co for Fe causes a nearly rigid shift in the chemical potential by adding two electrons per formula unit at higher binding energies. However at lower binding energies similar to 270 meV, the electron pocket at the center of the zone is absent, unlike in the Co-substituted Fe-based materials. This demonstrates that the rigid band picture is valid only at higher binding energies and breaks down closer to the chemical potential in BaCo2As2. We also observed the presence of a flat band near the Fermi energy that may have consequences for transport and thermodynamical properties. The experimental FS topology as well as band dispersion data are in reasonable agreement with the FP-LAPW calculations. C1 Iowa State Univ, Ames Lab, US DOE, Ames, IA 50011 USA.

The only limitation is that critical fluctuations should be weak so that the mean-field theory of the second-order phase transitions is applicable. By using the Rutgers relation, the zero-temperature value of the London penetration depth lambda(0) is related to the specific heat jump Delta C and the slope of upper critical field dH(c2)/dT at the transition temperature T-c, provided the data on Delta lambda = lambda(T) - lambda(0) are available in a broad temperature domain. We then provide a way to determine lambda(0), the quantity difficult to determine within many techniques. C1 [Kim, H.; Kogan, V. G.; Cho, K.; Tanatar, M.

Advances in scanning probe microscopy now provide the tools to visualize not only the frontier orbitals of chemical reaction partners and products, but their internal covalent bond configurations as well. We used noncontact atomic force microscopy to investigate reaction-induced changes in the detailed internal bond structure of individual oligo-(phenylene-1,2-ethynylenes) on a (100) oriented silver surface as they underwent a series of cyclization processes. Our images reveal the complex surface reaction mechanisms underlying thermally induced cyclization cascades of enediynes. Calculations using ab initio density functional theory provide additional support for the proposed reaction pathways.

TI Determining Cf-252 source strength by absolute passive neutron correlation counting SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Source calibration; Multiplicity counting; Neutron correlation analysis; Californium neutrons; Absolute metrology AB Physically small, lightly encapsulated, radionuclide sources containing Cf-252 are widely used for a vast variety of industrial, medical, educational and research applications requiring a convenient source of neutrons. For many quantitative applications, such as detector efficiency calibrations, the absolute strength of the neutron emission is needed. In this work we show how, by using a neutron multiplicity counter the neutron emission rate can be obtained with high accuracy. This provides an independent and alternative way to create reference sources in-house for laboratories such as ours engaged in international safeguards metrology. The method makes use of the unique and well known properties of the Cf-252 spontaneous fission system and applies advanced neutron correlation counting methods. We lay out the foundation of the method and demonstrate it experimentally. We show that accuracy comparable to the best methods currently used by national bodies to certify neutron source strengths is possible. (c) 2013 Elsevier B.V. All rights reserved.

Two beam tests were carried out with the 180 GeV/c muon beam at CERN using glass RPCs with gas gaps of 1.15 mm and equipped with readout strips with 1.27 mm pitch. This is the first beam test of RPCs with fine-pitch readout strips that explores precision tracking and triggering capabilities. RPC signals were acquired with precision timing and charge integrating readout electronics at both ends of the strips. The time resolution was measured to be better than 600 ps and the average spatial resolution was found to be 220 mu m using charge information and 287 mu m only using signal arrival time information. The dual-ended readout allows the determination of the average and the difference of the signal arrival times. The average time was found to be independent of the incident particle position along the strip and is useful for triggering purposes. The time difference yielded a determination of the hit position with a precision of 7.5 mm along the strip. These results demonstrate the feasibility using RPCs for fast and high-resolution triggering and tracking. (c) 2013 Elsevier B.V. All rights reserved.

A variety of experimental techniques have been employed to quantify the relative contributions of these processes. In modern studies lymphocytes are typically labeled with 5-bromo-2'-deoxyuridine (BrdU), deuterium, or the fluorescent dye carboxy-fluorescein diacetate succinimidyl ester (CFSE), their division history has been studied by monitoring telomere shortening and the dilution of T cell receptor excision circles (TRECs) or the dye CFSE, and clonal expansion has been documented by recording changes in the population densities of antigen specific cells. Proper interpretation of such data in terms of the underlying rates of T cell production, division, and death has proven to be notoriously difficult and involves mathematical modeling. We review the various models that have been developed for each of these techniques, discuss which models seem most appropriate for what type of data, reveal open problems that require better models, and pinpoint how the assumptions underlying a mathematical model may influence the interpretation of data. Elaborating various successful cases where modeling has delivered new insights in T cell population dynamics, this review provides quantitative estimates of several processes involved in the maintenance of naive and memory, CD4(+) and CD8(+) T cell pools in mice and men.

TI Comparison and Analysis of Zinc and Cobalt-Based Systems as Catalytic Entities for the Hydration of Carbon Dioxide SO PLOS ONE LA English DT Article ID POLARIZABLE CONTINUUM MODEL; HYDROGEN-BOND NETWORK; ANHYDRASE-II; ACTIVE-SITE; METHANOSARCINA-THERMOPHILA; PROTON-TRANSFER; CO2 CAPTURE; X-RAY; SPECTROSCOPIC MODEL; SYNTHETIC ANALOGS AB In nature, the zinc metalloenzyme carbonic anhydrase II (CAII) efficiently catalyzes the conversion of carbon dioxide (CO2) to bicarbonate under physiological conditions. Many research efforts have been directed towards the development of small molecule mimetics that can facilitate this process and thus have a beneficial environmental impact, but these efforts have met very limited success. Herein, we undertook quantum mechanical calculations of four mimetics, 1,5,9-triazacyclododedacane, 1,4,7,10-tetraazacyclododedacane, tris(4,5-dimethyl-2-imidazolyl)phosphine, and tris(2-benzimidazolylmethyl)amine, in their complexed form either with the Zn2+ or the Co2+ ion and studied their reaction coordinate for CO2 hydration. These calculations demonstrated that the ability of the complex to maintain a tetrahedral geometry and bind bicarbonate in a unidentate manner were vital for the hydration reaction to proceed favorably. Furthermore, these calculations show that the catalytic activity of the examined zinc complexes was insensitive to coordination states for zinc, while coordination states above four were found to have an unfavorable effect on product release for the cobalt counterparts.

TI Reaction Rate and Isomer-Specific Product Branching Ratios of C2H + C4H8: 1-Butene, cis-2-Butene, trans-2-Butene, and Isobutene at 79 K SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID PHOTOIONIZATION MASS-SPECTROMETRY; NEUTRAL-NEUTRAL REACTIONS; LAVAL NOZZLE APPARATUS; SET MODEL CHEMISTRY; ETHYNYL RADICAL C2H; TITANS ATMOSPHERE; RATE COEFFICIENTS; CROSS-SECTIONS; LOW-TEMPERATURE; HAZE FORMATION AB The reactions of C2H radicals with C4H8 isomers 1-butene, cis-2-butene, trans-2-butene, and isobutene are studied by laser photolysis-vacuum ultraviolet mass spectrometry in a Laval nozzle expansion at 79 K. Bimolecular-reaction rate constants are obtained by measuring the formation rate of the reaction product species as a function of the reactant density under pseudo-first-order conditions. The rate constants are (1.9 +/- 0.5) x 10(-10), (1.7 +/- 0.5) x 10(-10), (2.1 +/- 0.7) x 10(-10), and (1.8 +/- 0.9) x 10(-10) cm(3) s(-1) for the reaction of C2H with 1-butene, cis-2-butene, trans-2-butene, and isobutene, respectively. Bimolecular rate constants for 1-butene and isobutene compare well to values measured previously at 103 K using C2H chemiluminescence. Photoionization spectra of the reaction products are measured and fitted to ionization spectra of the contributing isomers. In conjunction with absolute-ionization cross sections, these fits provide isomer-resolved product branching fractions. The reaction between C2H and 1-butene yields (65 +/- 10)% C4H4 in the form of vinylacetylene and (35 +/- 10)% C5H6 in the form of 4-penten-1-yne. The cis-2-butene and trans-2-butene reactions yield solely 3-penten-1-yne, and no discrimination is made between cis- and trans-3-penten-1-yne. Last, the isobutene reaction yields (26 +/- 15)% 3-penten-1-yne, (35 +/- 15)% 2-methyl-1-buten-3-yne, and (39 +/- 15)% 4-methyl-3-penten-1-yne. The branching fractions reported for the C2H and butene reactions indicate that these reactions preferentially proceed via CH3 or C2H3 elimination rather than H-atom elimination. Within the experimental uncertainties, no evidence is found for the formation of cyclic species. C1 [Bouwman, Jordy; Leone, Stephen R.] Univ Calif Berkeley, Dept Chem, Berkeley, CA 94720 USA.

Given the likelihood of an inhospitable prebiotic atmosphere on early Earth, it is possible that impact processes of comets or other icy bodies were a source of prebiotic chemical compounds on the primitive planet. We observe that moderate shock pressures and temperatures within a CO2-rich icy mixture (36 GPa and 2800 K) produce a number of nitrogen containing heterocycles, which dissociate to form functionalized aromatic hydrocarbons upon expansion and cooling to ambient conditions. In contrast, higher shock conditions (48-60 GPa, 3700-4800 K) resulted in the synthesis of long carbon-chain molecules, CH4, and formaldehyde. All shock compression simulations at these conditions have produced significant quantities of simple C-N bonded compounds such as HCN, HNC, and HNCO upon expansion and cooling to ambient conditions. Our results elucidate a mechanism for impact synthesis of prebiotic molecules at realistic impact conditions that is independent of external constraints such as the presence of a catalyst, illuminating UV radiation, or pre-existing conditions on a planet.

TI Exploring Solid/Aqueous Interfaces with Ultradilute Electrokinetic Analysis of Liquid Microjets SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID WATER MICROJETS; SURFACES; GENERATION; CHARGE AB We describe a novel method that exploits electrokinetic streaming current measurements for the study of ion-interface affinity. Through the use of liquid microjets and ultradilute solutions (<1 mu M), we are able to overcome inherent difficulties in electrokinetic surface measurements engendered by changing double-layer thicknesses. Varying bulk KCl concentrations produce statistically significant changes in streaming current down at picomolar concentrations. Because the attending ion concentrations are below that from water autoionization, these data are compared with those from ultradilute HCl and KOH solutions assuming that the K+ and Cl- introduce no new counterions. This permits comparison of the individual effects of K+ and Cl- on the interface, evidencing a cooperative effect between these ions at silica surfaces. Altogether, these results establish the effectiveness of this experimental approach in revealing new ion-surface phenomena and indicate its promise for the general study of aqueous interfaces.

TI Quantum Tunneling Affects Engine Performance SO JOURNAL OF PHYSICAL CHEMISTRY LETTERS LA English DT Article ID SENSITIVITY-ANALYSIS; TRANSITION-STATE; COMBUSTION; IGNITION; KINETICS; SYSTEMS; MODEL; HO2 AB We study the role of individual reaction rates on engine performance, with an emphasis on the contribution of quantum tunneling. It is demonstrated that the effect of quantum tunneling corrections for the reaction HO2 + HO2 = H2O2 +O-2 can have a noticeable impact on the performance of a high-fidelity model of a compression-ignition (e.g., diesel) engine, and that an accurate prediction of ignition delay time for the engine model requires an accurate estimation of the tunneling correction for this reaction. The three-dimensional model includes detailed descriptions of the chemistry of a surrogate for a biodiesel fuel, as well as all the features of the engine, such as the liquid fuel spray and turbulence. This study is part of a larger investigation of how the features of the dynamics and potential energy surfaces of key reactions, as well as their reaction rate uncertainties, affect engine performance, and results in these directions are also presented here.

TI Carrier Multiplication in Quantum Dots within the Framework of Two Competing Energy Relaxation Mechanisms SO JOURNAL OF PHYSICAL CHEMISTRY LETTERS LA English DT Article ID MULTIPLE EXCITON GENERATION; SEMICONDUCTOR NANOCRYSTALS; MULTIEXCITON GENERATION; SILICON NANOCRYSTALS; SOLAR-CELLS; ELECTRONIC-STRUCTURE; AUGER RECOMBINATION; PBSE NANOCRYSTALS; COLLOIDAL PBSE; SINGLE-PHOTON AB The realization of high-yield, low-threshold carrier multiplication (CM) in semiconductor quantum dots (QDs) is a promising step toward third-generation photovoltaics (PV). Recent studies of QD solar cells have shown that CM can indeed produce greater-than-unity quantum efficiencies in photon-to-charge-carrier conversion, establishing the relevance of this process to practical PV technologies. While being appreciable, the reported CM yields are still not high enough for a significant increase in the power conversion efficiency over traditional bulk materials. At present, the design of nanomaterials with improved CM is hindered by a poor understanding of the mechanism underlying this process. Here, we present a possible solution to this problem by introducing a model that treats CM as a competition between impact-ionization-like scattering and non-CM energy losses. Importantly, it allows for evaluation of expected CM yields from fairly straightforward measurements of Auger recombination (inverse of CM) and near-band-edge carrier cooling. The validation of this model via a comparative CM study of PbTe, PbSe, and PbS QDs suggests that it indeed represents a predictive capability, which might help in the development of nanomaterials with improved CM performance.

The underlying -chitin organic matrix appears to influence magnetite crystal aggregate density and the diameter and curvature of the resulting rods, both of which likely play critical roles in determining the local mechanical properties of the mature radular teeth.

TI The Impacts of Cation Stoichiometry and Substrate Surface Quality on Nucleation, Structure, Defect Formation, and Intermixing in Complex Oxide Heteroepitaxy-LaCrO3 on SrTiO3(001) SO ADVANCED FUNCTIONAL MATERIALS LA English DT Article DE oxide heteroepitaxy; nonstoichiometry; intermixing; molecular beam epitaxy ID PULSED-LASER DEPOSITION; THIN-FILMS; INTERFACES; GROWTH; DIAMOND AB The ability to design and fabricate electronic devices with reproducible properties using complex oxides is critically dependent on our ability to controllably synthesize these materials in thin-film form. Structure-property relationships are intimately tied to film and interface composition. Here the effect of cation stoichiometry on structural quality and defect formation in LaCrO3 heteroepitaxial films prepared using molecular beam epitaxy is reported. From first principles the regions of stability of various candidate defects, along with the predicted effects of these defects on structural parameters, are calculated as a function of Cr and O chemical potential. Epitaxial LaCrO3 films readily nucleate and remain coherently strained on SrTiO3(001) over a wide range of La-to-Cr atom ratios, but La-rich films are of considerably lower structural quality than stoichiometric and Cr-rich films. Cation imbalances are accompanied by anti-site defect formation. Cation mixing occurs at the interface for all La-to-Cr ratios investigated and is not quenched by deposition on SrTiO3(001) at ambient temperature. Indiffused La atoms occupy Sr sites. Intermixing is effectively quenched by using molecular beam epitaxy to deposit LaCrO3 at ambient temperature on defect free Si(001). However, analogous pulsed laser deposition on Si is accompanied by cation mixing. C1 [Qiao, L.; Zhang, K. H. L.; Chambers, S.

TI SWIFT DISCOVERY OF A NEW SOFT GAMMA REPEATER, SGR J1745-29, NEAR SAGITTARIUS A* SO ASTROPHYSICAL JOURNAL LETTERS LA English DT Article DE pulsars: general; pulsars: individual (SGR J1745-29); stars: neutron; X-rays: bursts ID X-RAY PULSARS; GALACTIC-CENTER; TELESCOPE; BURSTS; GRBS AB Starting in 2013 February, Swift has been performing short daily monitoring observations of the G2 gas cloud near Sgr A* with the X-Ray Telescope to determine whether the cloud interaction leads to an increase in the flux from the Galactic center. On 2013 April 24 Swift detected an order of magnitude rise in the X-ray flux from the region near Sgr A*. Initially thought to be a flare from Sgr A*, the detection of a short hard X-ray burst from the same region by the Burst Alert Telescope suggested that the flare was from an unresolved new Soft Gamma Repeater, SGR J1745-29. Here we present the discovery of SGR J1745-29 by Swift, including analysis of data before, during, and after the burst. We find that the spectrum in the 0.3-10 keV range is well fit by an absorbed blackbody model with kT(BB) similar or equal to 1 keV and absorption consistent with previously measured values from the quiescent emission from Sgr A*, strongly suggesting that this source is at a similar distance. Only one SGR burst has been detected so far from the new source, and the persistent light curve shows little evidence of decay in approximately two weeks of monitoring after outburst. We discuss this light curve trend and compare it with those of other well covered SGR outbursts. We suggest that SGR J1745-29 belongs to an emerging subclass of magnetars characterized by low burst rates and prolonged steady X-ray emission one to two weeks after outburst onset. C1 [Kennea, J.

TI CIRCUMSTELLAR ABSORPTION IN DOUBLE DETONATION TYPE Ia SUPERNOVAE SO ASTROPHYSICAL JOURNAL LETTERS LA English DT Article DE binaries: close; novae, cataclysmic variables; nuclear reactions, nucleosynthesis, abundances; supernovae: general; white dwarfs ID ACCRETING WHITE-DWARFS; SODIUM-ABSORPTION; CLOSE BINARIES; MASS-TRANSFER; EVOLUTION; MERGERS; NOVAE; STARS; GAS; APPROXIMATIONS AB Upon formation, degenerate He core white dwarfs are surrounded by a radiative H-rich layer primarily supported by ideal gas pressure. In this Letter, we examine the effect of this H-rich layer on mass transfer in He+C/O double white dwarf binaries that will eventually merge and possibly yield a Type Ia supernova (SN Ia) in the double detonation scenario. Because its thermal profile and equation of state differ from the underlying He core, the H-rich layer is transferred stably onto the C/O white dwarf prior to the He core's tidal disruption. We find that this material is ejected from the binary system and sweeps up the surrounding interstellar medium hundreds to thousands of years before the SN Ia. The close match between the resulting circumstellar medium profiles and values inferred from recent observations of circumstellar absorption in SNe Ia gives further credence to the resurgent double detonation scenario.

TI Formation of heavy d-electron quasiparticles in Sr3Ru2O7 SO NEW JOURNAL OF PHYSICS LA English DT Article ID RUTHENATE SR3RU2O7 AB The phase diagram of Sr3Ru2O7 shows hallmarks of strong electron correlations despite the modest Coulomb interaction in the Ru 4d shell. We use angle-resolved photoelectron spectroscopy measurements to provide microscopic insight into the formation of the strongly renormalized heavy d-electron liquid that controls the physics of Sr3Ru2O7. Our data reveal itinerant Ru 4d-states confined over large parts of the Brillouin zone to an energy range of <6 meV, nearly three orders of magnitude lower than the bare band width. We show that this energy scale agrees quantitatively with a characteristic thermodynamic energy scale associated with quantum criticality and illustrate how it arises from a combination of back-folding due to a structural distortion and the hybridization of light and strongly renormalized, heavy quasiparticle bands. The resulting heavy Fermi liquid has a marked k-dependence of the renormalization which we relate to orbital mixing along individual Fermi surface sheets. C1 [Allan, M.

We observe a significantly greater sensitivity of the initial-state geometry to details of multiparticle production in these models compared to nucleus-nucleus collisions. In particular, we find that the size of the system produced in p + A collisions is very similar to the one produced in p + p collisions and predict comparable Hanbury-Brown-Twiss radii in the absence of flow in both systems. Differences in the eccentricities computed in the models are large, while differences among the generated flow coefficients upsilon(2) and upsilon(3) are smaller. For a large number of participants in proton-lead collisions, the upsilon(2) generated in the IP-Glasma model is comparable to the value obtained in proton-proton collisions. Viscous corrections to flow are large over characteristic lifetimes in the smaller size systems. In contrast, viscous contributions are significantly diminished over the longer space-time evolution of a heavy-ion collision.

Therefore, the entangled state of the BR system is dictated by unitarity even in the infalling patch. If, by monogamy of entanglement, B is not entangled with A, the horizon is replaced by a singularity or "firewall." To illustrate the radical nature of the ideas that are needed, I briefly discuss two approaches for avoiding a firewall: the identification of A with a subsystem of R; and a combination of patch complementarity with the Horowitz-Maldacena final-state proposal.

TI Superconducting and normal-state properties of APd(2)As(2) (A = Ca, Sr, Ba) single crystals SO PHYSICAL REVIEW B LA English DT Article ID HIGH-TEMPERATURE SUPERCONDUCTIVITY; HIGH-FIELD SUPERCONDUCTORS; MAGNETIC-SUSCEPTIBILITY; PURITY DEPENDENCE; PENETRATION DEPTH; TRANSITION; PNICTIDES; METALS; HC2 AB The synthesis and crystallography, magnetic susceptibility chi, magnetization M, specific heat C-p, in-plane electrical resistivity rho, and in-plane magnetic penetration depth measurements are reported for single crystals of APd(2)As(2) (A = Ca, Sr, Ba) versus temperature T and magnetic field H. The crystals were grown using PdAs self-flux. CaPd2As2 and SrPd2As2 crystallize in a collapsed body-centered tetragonal ThCr2Si2-type structure (I4/mmm), whereas BaPd2As2 crystallizes in the primitive tetragonal CeMg2Si2-type structure (P4/mmm), in agreement with literature data. The rho(T) data exhibit metallic behavior for all three compounds. Bulk superconductivity is reported for CaPd2As2 and SrPd2As2 below T-c = 1.27 and 0.92 K, respectively, whereas only a trace of superconductivity is found in BaPd2As2. No other phase transitions were observed. The chi(T) and M(H) data reveal anisotropic diamagnetism in the normal state, with chi(c) > chi(ab) for CaPd2As2 and BaPd2As2, and chi(c) < chi(ab) for SrPd2As2. The normal and superconducting state data indicate that CaPd2As2 and SrPd2As2 are conventional type-II nodeless s-wave electron-phonon superconductors. The electronic superconducting state heat capacity data for CaPd2As2, which has an extremely sharp heat capacity jump at T-c, are analyzed using our recent elaboration of the alpha-model of the BCS theory of superconductivity, which indicates that the s-wave gap in this compound is anisotropic in momentum space.

A manifestation of this conundrum is envisaged in the highly defective superconductor of KxFe2-ySe2. How can superconductivity survive under such crude conditions that call for strong electron localization? Here, we show that the Fe sublattice is locally distorted and accommodates two kinds of Fe valence environments giving rise to a bimodal bond-distribution, with short and long Fe bonds. The bimodal bonds are present even as the system becomes superconducting in the presence of antiferromagnetism, with the weight continuously shifting from the short to the long with increasing K content. Such a hybrid state is most likely found in cuprates as well while our results point to the importance of the local atomic symmetry by which exchange interactions between local moments materialize.

TI DISCOVERY OF TeV GAMMA-RAY EMISSION TOWARD SUPERNOVA REMNANT SNR G78.2+2.1 SO ASTROPHYSICAL JOURNAL LA English DT Article DE acceleration of particles; cosmic rays; gamma rays: general; ISM: supernova remnants ID PARTICLE-ACCELERATION; FERMI; HESS; SEARCH; COUNTERPART; 2CG078+2; CATALOG; ORIGIN AB We report the discovery of an unidentified, extended source of very-high-energy gamma-ray emission, VER J2019+407, within the radio shell of the supernova remnant SNR G78.2+2.1, using 21.4 hr of data taken by the VERITAS gamma-ray observatory in 2009. These data confirm the preliminary indications of gamma-ray emission previously seen in a two-year (2007-2009) blind survey of the Cygnus region by VERITAS. VER J2019+407, which is detected at a post-trials significance of 7.5 standard deviations in the 2009 data, is localized to the northwestern rim of the remnant in a region of enhanced radio and X-ray emission. It has an intrinsic extent of 0 degrees.23 +/- 0 degrees.03(stat-0 degrees.02sys)(+0 degrees.04) and its spectrum is well-characterized by a differential power law (dN/dE = N-0 x (E/TeV)-Gamma) with a photon index of Gamma = 2.37 +/- 0.14(stat) +/- 0.20(sys) and a flux normalization of N-0 = 1.5 +/- 0.2(stat) +/- 0.4(sys) x 10(-12) photon TeV-1 cm(-2) s(-1). This yields an integral flux of 5.2 +/- 0.8(stat) +/- 1.4(sys) x 10(-12) photon cm(-2) s(-1) above 320 GeV, corresponding to 3.7% of the Crab Nebula flux. We consider the relationship of the TeV gamma-ray emission with the GeV gamma-ray emission seen from SNR G78.2+2.1 as well as that seen from a nearby cocoon of freshly accelerated cosmic rays. Multiple scenarios are considered as possible origins for the TeV gamma-ray emission, including hadronic particle acceleration at the SNR shock.

The objects, with heavy-element cores in the range 5-30 M-circle plus, are assumed to accrete gas up to final masses of 10-15 Jupiter masses (M-Jup). After the formation process, which lasts 1-5 Myr and which ends with a "cold-start," low-entropy configuration, the bodies evolve at constant mass up to an age of several Gyr. Deuterium burning via proton capture is included in the calculation, and we determined the mass, M-50, above which more than 50% of the initial deuterium is burned. This often-quoted borderline between giant planets and brown dwarfs is found to depend only slightly on parameters, such as core mass, stellar mass, formation location, solid surface density in the protoplanetary disk, disk viscosity, and dust opacity. The values for M-50 fall in the range 11.6-13.6 M-Jup, in agreement with previous determinations that do not take the formation process into account. For a given opacity law during the formation process, objects with higher core masses form more quickly. The result is higher entropy in the envelope at the completion of accretion, yielding lower values of M-50. For masses above M-50, during the deuterium-burning phase, objects expand and increase in luminosity by one to three orders of magnitude. Evolutionary tracks in the luminosity versus time diagram are compared with the observed position of the companion to Beta Pictoris.

TI HOST GALAXY PROPERTIES AND HUBBLE RESIDUALS OF TYPE Ia SUPERNOVAE FROM THE NEARBY SUPERNOVA FACTORY SO ASTROPHYSICAL JOURNAL LA English DT Article DE dark energy; supernovae: general ID DIGITAL SKY SURVEY; INITIAL MASS FUNCTION; STAR-FORMING GALAXIES; LIGHT-CURVE SHAPES; STELLAR POPULATION SYNTHESIS; HIGH-REDSHIFT SUPERNOVAE; OR-EQUAL-TO; METALLICITY RELATION; SPACE-TELESCOPE; DARK-ENERGY AB We examine the relationship between Type Ia supernova (SN Ia) Hubble residuals and the properties of their host galaxies using a sample of 115 SNe Ia from the Nearby Supernova Factory. We use host galaxy stellar masses and specific star formation rates fitted from photometry for all hosts, as well as gas-phase metallicities for a subset of 69 star-forming (non-active galactic nucleus) hosts, to show that the SN Ia Hubble residuals correlate with each of these host properties. With these data we find new evidence for a correlation between SN Ia intrinsic color and host metallicity. When we combine our data with those of other published SN Ia surveys, we find the difference between mean SN Ia brightnesses in low- and high-mass hosts is 0.077 +/- 0.014 mag. When viewed in narrow (0.2 dex) bins of host stellar mass, the data reveal apparent plateaus of Hubble residuals at high and low host masses with a rapid transition over a short mass range (9.8 <= log(M*/M-circle dot) <= 10.4). Although metallicity has been a favored interpretation for the origin of the Hubble residual trend with host mass, we illustrate how dust in star-forming galaxies and mean SN Ia progenitor age both evolve along the galaxy mass sequence, thereby presenting equally viable explanations for some or all of the observed SN Ia host bias.

Combining Galaxy Evolution Explorer (GALEX) UV data with optical and near-infrared photometry, we employ stellar population synthesis techniques to measure SN Ia host galaxy stellar masses, star formation rates (SFRs), and reddening due to dust. We reinforce the key role of GALEX UV data in deriving accurate estimates of galaxy SFRs and dust extinction. Optical spectra of SN Ia host galaxies are fitted simultaneously for their stellar continua and emission lines fluxes, from which we derive high-precision redshifts, gas-phase metallicities, and Ha-based SFRs. With these data we show that SN Ia host galaxies present tight agreement with the fiducial galaxy mass-metallicity relation from Sloan Digital Sky Survey (SDSS) for stellar masses log(M*/M-circle dot) > 8.5 where the relation is well defined. The star formation activity of SN Ia host galaxies is consistent with a sample of comparable SDSS field galaxies, though this comparison is limited by systematic uncertainties in SFR measurements. Our analysis indicates that SN Ia host galaxies are, on average, typical representatives of normal field galaxies. C1 [Childress, M.; Aldering, G.; Aragon, C.; Bailey, S.; Fakhouri, H. K.; Hsiao, E.

SATELLITE COLOR AND MORPHOLOGY TRANSFORMATIONS SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: bulges; galaxies: clusters: general; galaxies: evolution; galaxies: halos; galaxies: statistics; X-rays: galaxies: clusters ID DIGITAL SKY SURVEY; SIMILAR-TO 1; EXTRAGALACTIC LEGACY SURVEY; DARK-MATTER HALOS; WIDE-FIELD SURVEY; STAR-FORMATION; STELLAR MASS; DENSITY RELATION; COSMOS SURVEY; RED SEQUENCE AB While the star formation rates and morphologies of galaxies have long been known to correlate with their local environment, the process by which these correlations are generated is not well understood. Galaxy groups are thought to play an important role in shaping the physical properties of galaxies before entering massive clusters at low redshift, and transformations of satellite galaxies likely dominate the buildup of local environmental correlations. To illuminate the physical processes that shape galaxy evolution in dense environments, we study a sample of 116 X-ray selected galaxy groups at z = 0.2-1 with halo masses of 10(13)-10(14) M-circle dot and centroids determined with weak lensing. We analyze morphologies based on Hubble Space Telescope imaging and colors determined from 31 photometric bands for a stellar mass-limited population of 923 satellite galaxies and a comparison sample of 16,644 field galaxies. Controlling for variations in stellar mass across environments, we find significant trends in the colors and morphologies of satellite galaxies with group-centric distance and across cosmic time. Specifically at low stellar mass (log(M-star/M-circle dot) = 9.8-10.3), the fraction of disk-dominated star-forming galaxies declines from >50% among field galaxies to <20% among satellites near the centers of groups. This decline is accompanied by a rise in quenched galaxies with intermediate bulge+disk morphologies, and only a weak increase in red bulge-dominated systems. These results show that both color and morphology are influenced by a galaxy's location within a group halo. We suggest that strangulation and disk fading alone are insufficient to explain the observed morphological dependence on environment, and that galaxy mergers or close tidal encounters must play a role in building up the population of quenched galaxies with bulges seen in dense environments at low redshift.

TI SATELLITES IN MILKY-WAY-LIKE HOSTS: ENVIRONMENT DEPENDENCE AND CLOSE PAIRS SO ASTROPHYSICAL JOURNAL LA English DT Article DE dark matter; Galaxy: fundamental parameters; Galaxy: halo; Magellanic Clouds ID DARK-MATTER HALO; HORIZONTAL-BRANCH STARS; LARGE-MAGELLANIC-CLOUD; VIRGO CLUSTER; LOCAL GROUP; GALACTIC SATELLITES; MASS-DISTRIBUTION; SCALE STRUCTURE; PROPER MOTION; GALAXIES AB Previous studies showed that an estimate of the likelihood distribution of the Milky Way (MW) halo mass can be derived using the properties of the satellites similar to the Large and Small Magellanic Clouds (LMC and SMC). However, it would be straightforward to interpret such an estimate only if the properties of the Magellanic Clouds (MCs) are fairly typical and are not biased by the environment. In this study, we explore whether the environment of the MW affects the properties of the SMC and LMC such as their velocities. To test for the effect of the environment, we compare velocity distributions for MC-sized subhalos around MW hosts in a sample selected simply by mass and in the second sample of such halos selected with additional restrictions on the distance to the nearest cluster and the local galaxy density, designed to mimic the environment of the Local Group (LG). We find that satellites in halos in the LG-like environments do have somewhat larger velocities, as compared to the halos of similar mass in the sample without environmental constraints. For example, the fraction of subhalos matching the velocity of the LMC is 23% +/- 2% larger in the LG-like environments. We derive the host halo likelihood distribution for the samples in the LG-like environment and in the control sample and find that the environment does not significantly affect the derived likelihood. We use the updated properties of the SMC and LMC to derive the constraint on the MW halo mass of log (M-200/M-circle dot) = 12.06(-0.19)(+0.31) (90% confidence interval). We also explore the incidence of close pairs with relative velocities and separations similar to those of the LMC and SMC and find that such pairs are quite rare among Delta CDM halos. Only 2% of halos in the MW mass range have a relatively close pair (Delta r < 40 kpc and Delta s < 160 km s(-1)) of subhalos with circular velocities v(circ) > 50 km s(-1). Pairs with masses and separations similar to those of the LMC and SMC (Delta r(MC) = 23.4 +/- 10 kpc and Delta s(MC) = 128 +/- 32 km s(-1)) are found only in one out of approximate to 30,000 MW-sized halos. Interestingly, the halo mass likelihood distribution for host halos constrained to have MC-like close pairs of subhalos is quite different from the global likelihood from which the MW halo mass constraint discussed above was derived. Taking into account the close separation of the MCs in the Busha et al. method results in the shift of the MW halo mass estimate to smaller masses, with the peak shifting approximately by a factor of two.

Megan TI THE NUCLEAR SPECTROSCOPIC TELESCOPE ARRAY (NuSTAR) HIGH-ENERGY X-RAY MISSION SO ASTROPHYSICAL JOURNAL LA English DT Article DE space vehicles: instruments; X-rays: general ID ACTIVE GALACTIC NUCLEI; SUPERMASSIVE BLACK-HOLE; DEEP FIELD-SOUTH; SUPERNOVA REMNANT G1.9+0.3; SOFT GAMMA-REPEATERS; MS SOURCE CATALOGS; BROAD IRON LINES; XMM-NEWTON; ASCA OBSERVATIONS; NEUTRON-STAR AB The Nuclear Spectroscopic Telescope Array (NuSTAR) mission, launched on 2012 June 13, is the first focusing high-energy X-ray telescope in orbit. NuSTAR operates in the band from 3 to 79 keV, extending the sensitivity of focusing far beyond the similar to 10 keV high-energy cutoff achieved by all previous X-ray satellites. The inherently low background associated with concentrating the X-ray light enables NuSTAR to probe the hard X-ray sky with a more than 100-fold improvement in sensitivity over the collimated or coded mask instruments that have operated in this bandpass. Using its unprecedented combination of sensitivity and spatial and spectral resolution, NuSTAR will pursue five primary scientific objectives: (1) probe obscured active galactic nucleus (AGN) activity out to the peak epoch of galaxy assembly in the universe (at z less than or similar to 2) by surveying selected regions of the sky; (2) study the population of hard X-ray-emitting compact objects in the Galaxy by mapping the central regions of the Milky Way; (3) study the non-thermal radiation in young supernova remnants, both the hard X-ray continuum and the emission from the radioactive element Ti-44; (4) observe blazars contemporaneously with ground-based radio, optical, and TeV telescopes, as well as with Fermi and Swift, to constrain the structure of AGN jets; and (5) observe line and continuum emission from core-collapse supernovae in the Local Group, and from nearby Type Ia events, to constrain explosion models. During its baseline two-year mission, NuSTAR will also undertake a broad program of targeted observations. The observatory consists of two co-aligned grazing-incidence X-ray telescopes pointed at celestial targets by a three-axis stabilized spacecraft. Deployed into a 600 km, near-circular, 6 degrees inclination orbit, the observatory has now completed commissioning, and is performing consistent with pre-launch expectations. NuSTAR is now executing its primary science mission, and with an expected orbit lifetime of 10 yr, we anticipate proposing a guest investigator program, to begin in late 2014.

TI THE IMPACT OF METALLICITY ON THE RATE OF TYPE Ia SUPERNOVAE SO ASTROPHYSICAL JOURNAL LA English DT Article DE binaries: close; supernovae: general; white dwarfs ID DELAY-TIME DISTRIBUTION; ASYMPTOTIC GIANT BRANCH; STAR-FORMATION RATE; GAMMA-RAY BURSTS; WHITE-DWARF MERGERS; FINAL MASS RELATION; EARLY-TYPE GALAXIES; DIGITAL SKY SURVEY; HOST GALAXIES; HIGH-REDSHIFT AB The metallicity of a star strongly affects both its evolution and the properties of the stellar remnant that results from its demise. It is generally accepted that stars with initial masses below similar to 8 M-circle dot leave behind white dwarfs and that some sub-population of these lead to Type Ia supernovae (SNe Ia). However, it is often tacitly assumed that metallicity has no effect on the rate of SNe Ia. We propose that a consequence of the effects of metallicity is to significantly increase the SN Ia rate in lower-metallicity galaxies, in contrast to previous expectations. This is because lower-metallicity stars leave behind higher-mass white dwarfs, which should be easier to bring to explosion. We first model SN Ia rates in relation to galaxy masses and ages alone, finding that the elevation in the rate of SNe Ia in lower-mass galaxies measured by Lick Observatory SN Search is readily explained. However, we then see that models incorporating this effect of metallicity agree just as well. Using the same parameters to estimate the cosmic SN Ia rate, we again find good agreement with data up to z approximate to 2. We suggest that this degeneracy warrants more detailed examination of host galaxy metallicities. We discuss additional implications, including for hosts of high-z SNe Ia, the SN Ia delay time distribution, super-Chandrasekhar SNe, and cosmology.

Simultaneous enhancement of strength and tensile ductility is achieved. The strain rate sensitivity is found to decrease with decreasing grain sizes (similar to 150-450 nm). A new Hall-petch relationship is presented and discussed. The analyses on the internal friction peaks at around 70 degrees C suggest that twins could play the primary role for the strain hardening of the annealed nanostructured Ti, consistent with the miniscule activation volumes.

Dai, Sheng TI Structure of Au-15(SR)(13) and Its Implication for the Origin of the Nucleus in Thiolated Gold Nanoclusters SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID CLUSTERS AB Au-15(SR)(13) is the smallest stable thiolated gold nanocluster experimentally identified so far, and its elusive structure may hold the key to the origin of the nucleus in the formation of thiolated gold nanoclusters. By an extensive exploration of possible isomers by density functional theory, we arrive at a novel structure for Au-15(SR)(13) with high stability and whose optical absorption characteristics match those of the experiment. Different from the previous structures and the prevailing working hypothesis about the construction of thiolated gold nanoclusters, the Au-15(SR)(13) model features a cyclic [Au(I)-SR] pentamer interlocked with one staple trimer motif protecting the tetrahedral Au-4 nucleus, together with another trimer motif. This structure suggests that Au-15(SR)(13) is a transitional composition from an [Au(I)-SR] polymer such as Au-10(SR)(10) to larger Au-n(SR)(m) (n > m) dusters that have only the staple motifs and that the nucleation process starts from the Au-4 core.

Here, we report the time scale and efficiency of charge separation and recombination in a vapor-deposited SMOSC material that produces 5.81% power conversion efficiency. Transient absorption and time-resolved photoluminescence (trPL) studies of thin film blends comprising DTDCTB, a narrow-band gap electron donor, and either C-60 or C-70 as an electron acceptor show that charge separation occurs in similar to 100 fs, while charge recombination takes place over sub-ns and ns time scales. trPL indicates a donor electron-hole pair lifetime of similar to 33 ps in the neat film and reveals that similar to 20% of donors fail to charge separate in donor-acceptor mixed films, likely owing to some spatially extended donor-rich regions that interact poorly with acceptors. Our results suggest that morphological manipulations of this material could further improve device efficiency.

TI Fe3-xTixO4 Nanoparticles as Tunable Probes of Microbial Metal Oxidation SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID MAGNETIC CIRCULAR-DICHROISM; IRON-OXIDE NANOPARTICLES; 2P ABSORPTION-SPECTRA; X-RAY-ABSORPTION; GENOMIC PERSPECTIVE; OXIDIZING BACTERIA; ELECTRON-TRANSFER; THIN-FILMS; REDUCTION; TITANOMAGNETITE AB Present and emerging biotechnological applications for iron (oxyhydr)oxide nanomaterials depend on their interaction with microorganisms, as do their toxicity, transport, and fate in biological and environmental systems. However, mass or electron transfer along key molecular pathways at microbe-nanomaterial interfaces is extremely difficult to quantify because of system complexity. Inspired by Fe(II)-oxidizing microbes widespread in nature, we isolate and characterize one such pathway by examining the oxidation of Fe3-xTixO4 (magnetite-titanomagnetite) nanoparticles by the bacterial electron transfer enzyme MtoA, a decaheme c-type cytochrome. Oxidation by MtoA was studied as a function of the thermodynamic driving force for electron transfer by controlling the Ti(IV) doping content (x), which tunes the solid-state Fe(II)/Fe(III) ratio built into the nanoparticles. A higher Fe(II)/Fe(III) ratio appears to systematically increase the electron transfer kinetics to the cytochrome. In situ X-ray diffraction indicated that, during oxidation, the spinel ferrite lattice remains intact while structural Fe(II) is progressively depleted. Surface and atomic site specific Fe L-2,L-3-edge X-ray magnetic circular dichroism indicated that MtoA directly accesses magnetically ordered B-sublattice Fe(II) at the interface. This study provides the first quantitative insights into an isolated molecular pathway for biotransformation of iron (oxyhydr)oxide nanomaterials, and more generally, it also illustrates new techniques for probing these pathways in detail, featuring use of tailored nanoparticles, purified metalloenzyme, and synchrotron X-ray absorption spectroscopies.

While motility and atomic structures have been well-characterized for various members of the kinesin family, not much is known about ATP hydrolysis inside the active site. Here, we study ATP hydrolysis mechanisms in the kinesin-5 protein Eg5 by using combined quantum mechanics/molecular mechanics metadynamics simulations. Approximately 200 atoms at the catalytic site are treated by a dispersion-corrected density functional and, in total, 13 metadynamics simulations are performed with their cumulative time reaching similar to 0.7 ns. Using the converged runs, we compute free energy surfaces and obtain a few hydrolysis pathways. The pathway with the lowest free energy barrier involves a two-water chain and is initiated by the P-gamma-O-beta dissociation concerted with approach of the lytic water to P gamma O3-. This immediately induces a proton transfer from the lytic water to another water, which then gives a proton to the conserved Glu270. Later, the proton is transferred back from Glu270 to HPO42- via another hydrogen-bonded chain. We find that the reaction is favorable when the salt bridge between Glu270 in switch II and Arg234 in switch I is transiently broken, which facilitates the ability of Glu270 to accept a proton. When ATP is placed in the ADP-bound conformation of Eg5, the ATP-Mg moiety is surrounded by many water molecules and Thr107 blocks the water chain, which together make the hydrolysis reaction less favorable. The observed two-water chain mechanisms are rather similar to those suggested in two other motors, myosin and F-1-ATPase, raising the possibility of a common mechanism.

In addition to increasing the material complexity and functionality, SWNTs can probe the interfacial processes in the hybrid system. In this work, SWNT-TiO2 core/shell hybrid nanostructures were found to exhibit unique electrical behavior in response to UV illumination and acetone vapors. By experimental and theoretical studies of UV and acetone sensitivities of different SWNT-TiO2 hybrid systems, we established a fundamental understanding on the interfacial charge transfer between photoexcited TiO2 and SWNTs as well as the mechanism of acetone sensing. We further demonstrated a practical application of photoinduced acetone sensitivity by fabricating a microsized room temperature acetone sensor that showed fast, linear, and reversible detection of acetone vapors with concentrations in few parts per million range.

TI A Structure-Based Model of Energy Transfer Reveals the Principles of Light Harvesting in Photosystem II Supercomplexes SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID STRUCTURE-BASED SIMULATION; LINEAR OPTICAL-SPECTRA; EXCITATION-ENERGY; COMPLEX-II; CHARGE SEPARATION; CRYSTAL-STRUCTURE; REACTION CENTERS; GREEN PLANTS; SUPRAMOLECULAR ORGANIZATION; THYLAKOID MEMBRANE AB Photosystem II (PSII) initiates photosynthesis in plants through the absorption of light and subsequent conversion of excitation energy to chemical energy via charge separation. The pigment binding proteins associated with PSII assemble in the grana membrane into PSII supercomplexes and surrounding light harvesting complex II trimers. To understand the high efficiency of light harvesting in PSII requires quantitative insight into energy transfer and charge separation in PSII supercomplexes. We have constructed the first structure-based model of energy transfer in PSII supercomplexes. This model shows that the kinetics of light harvesting cannot be simplified to a single rate limiting step. Instead, substantial contributions arise from both excitation diffusion through the antenna pigments and transfer from the antenna to the reaction center (RC), where charge separation occurs. Because of the lack of a rate-limiting step, fitting kinetic models to fluorescence lifetime data cannot be used to derive mechanistic insight on light harvesting in PSII. This model will clarify the interpretation of chlorophyll fluorescence data from PSII supercomplexes, grana membranes, and leaves.

Currently, this pathway is of great interest because of the critical role that isoprenoids play in basic cellular processes, as well as the industrial value of metabolites such as isoprene. Although the regulation of several pathway genes has been described, there is a paucity of information regarding system level regulation and control of the pathway. To address these limitations, we examined Bacillus subtilis grown under multiple conditions and determined the relationship between altered isoprene production and gene expression patterns. We found that with respect to the amount of isoprene produced, terpenoid genes fall into two distinct subsets with opposing correlations. The group whose expression levels positively correlated with isoprene production included dxs, which is responsible for the commitment step in the pathway, ispD, and two genes that participate in the mevalonate pathway, yhfS and pksG. The subset of terpenoid genes that inversely correlated with isoprene production included ispH, ispF, hepS, uppS, ispE, and dxr. A genome-wide partial least squares regression model was created to identify other genes or pathways that contribute to isoprene production. These analyses showed that a subset of 213 regulated genes was sufficient to create a predictive model of isoprene production under different conditions and showed correlations at the transcriptional level. We conclude that gene expression levels alone are sufficiently informative about the metabolic state of a cell that produces increased isoprene and can be used to build a model that accurately predicts production of this secondary metabolite across many simulated environmental conditions.

Although bacteria are assumed to play a major role in kelp forest carbon cycling, knowledge of the composition and diversity of these bacterial communities is lacking. Bacterial communities on the surface of Macrocystis pyrifera and adjacent seawater were sampled at the Hopkins Marine Station in Monterey Bay, CA, and further studied using 454-tag pyrosequencing of 16S RNA genes. Our results suggest that M. pyrifera-dominated kelp forests harbor distinct microbial communities that vary temporally. The distribution of sequence tags assigned to Gammaproteobacteria, Alphaproteobacteria and Bacteriodetes differed between the surface of the kelp and the surrounding water. Several abundant Rhodobacteraceae, uncultivated Gammaproteobacteria and Bacteriodetes-associated tags displayed considerable temporal variation, often with similar trends in the seawater and the surface of the kelp. Bacterial community structure and membership correlated with the kelp surface serving as host, and varied over time. Several kelp-specific taxa were highly similar to other bacteria known to either prevent the colonization of eukaryotic larvae or exhibit antibacterial activities. Some of these kelp-specific bacterial associations might play an important role for M. pyrifera. This study provides the first assessment of the diversity and phylogenetic profile of the bacterial communities associated with M. pyrifera.

TI Electromagnetic cascade in high-energy electron, positron, and photon interactions with intense laser pulses SO PHYSICAL REVIEW A LA English DT Article ID EXTREME FIELD LIMITS; COMPTON-SCATTERING; PLASMA; LIGHT; WAVE; ACCELERATOR; REGIME; DESIGN; DIRAC; BEAMS AB The interaction of high-energy electrons, positrons, and photons with intense laser pulses is studied in head-on collision geometry. It is shown that electrons and/or positrons undergo a cascade-type process involving multiple emissions of photons. These photons can consequently convert into electron-positron pairs. As a result charged particles quickly lose their energy developing an exponentially decaying energy distribution, which suppresses the emission of high-energy photons, thus reducing the number of electron-positron pairs being generated. Therefore, this type of interaction suppresses the development of the electromagnetic avalanche-type discharge, i.e., the exponential growth of the number of electrons, positrons, and photons does not occur in the course of interaction. The suppression will occur when three-dimensional effects can be neglected in the transverse particle orbits, i.e., for sufficiently broad laser pulses with intensities that are not too extreme. The final distributions of electrons, positrons, and photons are calculated for the case of a high-energy e-beam interacting with a counterstreaming, short intense laser pulse. The energy loss of the e-beam, which requires a self-consistent quantum description, plays an important role in this process, as well as provides a clear experimental observable for the transition from the classical to quantum regime of interaction.

A mixed-action scheme is used with domain-wall valence fermions computed on the staggered MILC sea-quark configurations. The matrix element is determined by making use of the Feynman-Hellmann theorem which relates this strange matrix element to the change in the nucleon mass with respect to the strange-quark mass.

Tailored specifically for biomass application, the process described here consists of six primary unit operations: (1) a Na2CO3 bed for HCl removal, (2) two regenerable ZnO beds in parallel for bulk H2S removal, (3) a ZnO bed for H2S polishing, (4) a NiCu/SBA-16 sorbent for trace metal (e.g., AsH3) removal, (5) a steam reforming catalyst bed for tars and light hydrocarbon reformation and NH3 decomposition, and (6) a Cu-based LT-WGS catalyst bed. Simulated biomass-derived syngas containing possible inorganic contaminants (H2S, AsH3, HCl, and NH3) and hydrocarbons (methane, ethylene, benzene, and naphthalene) was used to demonstrate process effectiveness. The efficiency of the process was demonstrated for a period of 175 h, during which time no signs of deactivation were observed. However, postrun analysis revealed that small levels of sulfur slipped through the sorbent bed train to the two downstream catalytic beds. Future improvements will be made to the trace metal polishing sorbent to ensure complete inorganic contaminant removal (to low parts per billion level) prior to the catalytic steps. However, dual regenerating ZnO beds were effective for continuous removal for the vast majority of the sulfur present in the feed gas. The process was effective for complete AsH3 and HCl removal. The steam reforming catalyst completely reformed all the hydrocarbons present in the feed (methane, ethylene, benzene, and naphthalene) to additional syngas. However, postrun evaluation, under kinetically controlled conditions, indicates some deactivation of the steam reforming catalyst occurred. Spent catalyst characterization suggests this can be attributed, in part, to coke formation, likely due to the presence of benzene and/or naphthalene in the feed. Future adaptation of this technology may require dual, regenerable steam reformers. The process and materials described in this report hold promise for the warm cleanup of a variety of contaminant species within warm syngas.

TI New insights into the laser produced electron-positron pairs SO NEW JOURNAL OF PHYSICS LA English DT Article ID SOLID INTERACTIONS; PLASMA; PARTICLES; IGNITION; CREATION AB We report new results from the intense laser target interaction experiment that produces relativistic electron-positron pairs. Laser to electron energy transfer, inferred using x-ray and neutron measurements, was found to be consistent with the measured positrons. To increase the number of positrons, one needs to deliver a greater number of relativistic electrons from the laser-plasma interaction to the high Z gold target. A large preplasma was found to have a negative impact for this purpose, while the laser could produce hotter electrons in such preplasma. The peak energy shift in the positron spectrum is confirmed as the post-acceleration in the sheath potential behind the target. The results were supported by a collisional one-dimensional particle-in-cell code. This experiment was performed using the high-power LFEX laser at the Institute of Laser Engineering at Osaka University using a suite of diagnostics measuring electrons, positrons, x-rays and neutrons from the laser-target interaction at the relativistic regime.

We show that the introduction of spatially inhomogeneous interactions, e.g., generated by optically controlled collisions, induce negative differential conductance in the transport of atoms in one-dimensional optical lattices. Specifically, we simulate the dynamics of interacting fermionic atoms via a micro-canonical transport formalism within both a mean-field and a higher-order approximation, as well as with a time-dependent density-matrix renormalization group (DMRG). For weakly repulsive interactions, a quasi-steady-state atomic current develops that is similar to the situation occurring for electronic systems subject to an external voltage bias. At the mean-field level, we find that this atomic current is robust against the details of how the interaction is switched on. Further, a conducting-non-conducting transition exists when the interaction imbalance exceeds some threshold from both our approximate and time-dependent DMRG simulations. This transition is preceded by the atomic equivalent of negative differential conductivity observed in transport across solid-state structures.

CA CLAS Collaboration TI Cross sections for the gamma p -> K*(+)Lambda and gamma p -> K*(+)Sigma(0) reactions measured at CLAS SO PHYSICAL REVIEW C LA English DT Article ID SYSTEM AB The first high-statistics cross sections for the reactions gamma p -> K*(+)Lambda and gamma p -> K*(+)Sigma(0) were measured using the CLAS detector at photon energies between threshold and 3.9 GeV at the Thomas Jefferson National Accelerator Facility. Differential cross sections are presented over the full range of the center-of-mass angles, and then fitted to Legendre polynomials to extract the total cross section. Results for the K*(+)Lambda final state are compared with two different calculations in an isobar and a Regge model, respectively. Theoretical calculations significantly underestimate the K*(+)Lambda total cross sections between 2.1 and 2.6 GeV, but are in better agreement with present data at higher photon energies.

We can now peer into a metal during processing without destroying it using proton radiography. Understanding the link between processing and structure is important because structure profoundly affects the properties of engineering materials. Synchrotron x-ray radiography has enabled real-time glimpses into metal solidification. However, x-ray energies favor the examination of small volumes and low density metals. Here we use high energy proton radiography for the first time to image a large metal volume (>10,000 mm(3)) during melting and solidification. We also show complementary x-ray results from a small volume (<1 mm(3)), bridging four orders of magnitude. Real-time imaging will enable efficient process development and the control of structure evolution to make materials with intended properties; it will also permit the development of experimentally informed, predictive structure and process models.

TI Phase diagram and magnetic structures of the Co-bearing dugganites Pb(3)TeCo(3)A(2)O(14) (A = V, P) SO JOURNAL OF PHYSICS-CONDENSED MATTER LA English DT Article ID POWDER DIFFRACTION; LANGASITE FAMILY; CRYSTALS; GROWTH AB Exhibiting rich magnetic behaviour and potentially multiferroic properties, the dugganites, a Te6+ containing subgroup of the langasite series, are an attractive family of compounds for future study. It was recently shown that Pb-bearing members of the dugganite series undergo distortions away from the P321 symmetry that is characteristic of the langasites. Here, we detail the consequences these distortions have on the magnetism exhibited by Pb3TeCo3V2O14 and Pb3TeCo3P2O14, solving the magnetic structures of both compounds with respect to a new supercell. Using neutron scattering and magnetic susceptibility measurements, we show that small applied magnetic fields can seriously perturb the delicate magnetic states in both of these systems. This is further demonstrated by presenting how doping P5+ onto the nonmagnetic V5+ site completely changes the magnetic structure from either of the end series members. Finally, it is shown using inelastic neutron scattering and magnetic susceptibility measurements that Pb3TeCo3V2O14 can be characterized using a model for isosceles trimers, which do not exist in the previously reported P321 subcell.

By replacing 0.5% and 4.0% of Al with Sr, we show that the addition of Sr lowers the self-diffusion of Al and Si of the liquid and reduces the nearest-neighbor correlation between Si atoms. The simulation provides an explanation for the change in morphology of the eutectic phases observed in rapidly solidified Al-Si alloys modified with Sr. C1 [Yue, G. Q.; Wu, S.; Shen, B.; Wang, S.

TI Functional anatomy of distant-acting mammalian enhancers SO PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY B-BIOLOGICAL SCIENCES LA English DT Review DE enhancer; gene regulation; mutation; mouse genomics ID PROSTATE-CANCER RISK; VAN-BUCHEM-DISEASE; BETA-GLOBIN GENE; IN-VIVO; TARGETED DELETION; VIRUS INDUCTION; CROHNS-DISEASE; HUMAN GENOME; EXPRESSION; GATA4 AB Transcriptional enhancers are a major class of functional element embedded in the vast non-coding portion of the human genome. Acting over large genomic distances, enhancers play critical roles in the tissue and cell type-specific regulation of genes, and there is mounting evidence that they contribute to the aetiology of many human diseases. Methods for genome-wide mapping of enhancer regions are now available, but the functional architecture contained within human enhancer elements remains unclear. Here, we review recent approaches aimed at understanding the functional anatomy of individual enhancer elements, using systematic qualitative and quantitative assessments of mammalian enhancer variants in cultured cells and in vivo. These studies provide direct insight into common architectural characteristics of enhancers including the presence of multiple transcription factor-binding sites and the mixture of both transcriptionally activating and repressing domains within the same enhancer. Despite such progress in understanding the functional composition of enhancers, the inherent complexities of enhancer anatomy continue to limit our ability to predict the impact of sequence changes on in vivo enhancer function. While providing an initial glimpse into the mutability of mammalian enhancers, these observations highlight the continued need for experimental enhancer assessment as genome sequencing becomes routine in the clinic.

TI Quantifying Extrinsic Noise in Gene Expression Using the Maximum Entropy Framework SO BIOPHYSICAL JOURNAL LA English DT Article ID ESCHERICHIA-COLI; SINGLE-CELL; SACCHAROMYCES-CEREVISIAE; REGULATORY NETWORKS; PROTEIN EXPRESSION; STOCHASTICITY; FLUCTUATIONS; LEVEL AB We present a maximum entropy framework to separate intrinsic and extrinsic contributions to noisy gene expression solely from the profile of expression. We express the experimentally accessible probability distribution of the copy number of the gene product (mRNA or protein) by accounting for possible variations in extrinsic factors. The distribution of extrinsic factors is estimated using the maximum entropy principle. Our results show that extrinsic factors qualitatively and quantitatively affect the probability distribution of the gene product. We work out, in detail, the transcription of mRNA from a constitutively expressed promoter in Escherichia coli. We suggest that the variation in extrinsic factors may account for the observed wider-than-Poisson distribution of mRNA copy numbers. We successfully test our framework on a numerical simulation of a simple gene expression scheme that accounts for the variation in extrinsic factors. We also make falsifiable predictions, some of which are tested on previous experiments in E. coli whereas others need verification. Application of the presented framework to more complex situations is also discussed. C1 Brookhaven Natl Lab, Dept Biosci, Upton, NY 11973 USA.

TI Direct electrolytic dissolution of silicate minerals for air CO2 mitigation and carbon-negative H-2 production SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE air capture; carbon dioxide; electrochemistry; hydrogen; mineral weathering ID AMBIENT AIR; CAPTURE; DIOXIDE; ALKALINITY; SEAWATER; STORAGE; WORLD; CYCLE; POWER; COST AB We experimentally demonstrate the direct coupling of silicate mineral dissolution with saline water electrolysis and H-2 production to effect significant air CO2 absorption, chemical conversion, and storage in solution. In particular, we observed as much as a 10(5)-fold increase in OH-concentration (pH increase of up to 5.3 units) relative to experimental controls following the electrolysis of 0.25 M Na2SO4 solutions when the anode was encased in powdered silicate mineral, either wollastonite or an ultramafic mineral. After electrolysis, full equilibration of the alkalized solution with air led to a significant pH reduction and as much as a 45-fold increase in dissolved inorganic carbon concentration. This demonstrated significant spontaneous air CO2 capture, chemical conversion, and storage as a bicarbonate, predominantly as NaHCO3. The excess OH-initially formed in these experiments apparently resulted via neutralization of the anolyte acid, H2SO4, by reaction with the base mineral silicate at the anode, producing mineral sulfate and silica. This allowed the NaOH, normally generated at the cathode, to go unneutralized and to accumulate in the bulk electrolyte, ultimately reacting with atmospheric CO2 to form dissolved bicarbonate. Using nongrid or nonpeak renewable electricity, optimized systems at large scale might allow relatively high-capacity, energy-efficient (<300 kJ/mol of CO2 captured), and inexpensive (<$100 per tonne of CO2 mitigated) removal of excess air CO2 with production of carbon-negative H-2. Furthermore, when added to the ocean, the produced hydroxide and/or (bi) carbonate could be useful in reducing sea-to-air CO2 emissions and in neutralizing or offsetting the effects of ongoing ocean acidification.

TI Network topology for the formation of solvated electrons in binary CaO-Al2O3 composition glasses SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE amorphous network; glass topology; electron localization ID CALCIUM ALUMINATE GLASSES; DENSITY-FUNCTIONAL CALCULATIONS; MOLECULAR-DYNAMICS; HYDRATED ELECTRON; DIFFRACTION; PERSPECTIVE; NEUTRON; SYSTEMS; NMR AB Glass formation in the CaO-Al2O3 system represents an important phenomenon because it does not contain typical network-forming cations. We have produced structural models of CaO-Al2O3 glasses using combined density functional theory-reverse Monte Carlo simulations and obtained structures that reproduce experiments (X-ray and neutron diffraction, extended X-ray absorption fine structure) and result in cohesive energies close to the crystalline ground states. The O-Ca and O-Al coordination numbers are similar in the eutectic 64 mol % CaO (64CaO) glass [comparable to 12CaO center dot 7Al(2)O(3) (C12A7)], and the glass structure comprises a topologically disordered cage network with large-sized rings. This topologically disordered network is the signature of the high glass-forming ability of 64CaO glass and high viscosity in the melt. Analysis of the electronic structure reveals that the atomic charges for Al are comparable to those for Ca, and the bond strength of Al-O is stronger than that of Ca-O, indicating that oxygen is more weakly bound by cations in CaO-rich glass. The analysis shows that the lowest unoccupied molecular orbitals occurs in cavity sites, suggesting that the C12A7 electride glass [Kim SW, Shimoyama T, Hosono H (2011) Science 333(6038): 7174] synthesized from a strongly reduced high-temperature melt can host solvated electrons and bipolarons. Calculations of 64CaO glass structures with few subtracted oxygen atoms (additional electrons) confirm this observation. The comparable atomic charges and coordination of the cations promote more efficient elemental mixing, and this is the origin of the extended cage structure and hosted solvated (trapped) electrons in the C12A7 glass.

Toward this end, we used single-dimension ultra-high-pressure liquid chromatography mass spectrometry to investigate the comprehensive "intact" proteome of the Gram-negative bacterial pathogen Salmonella Typhimurium. Top-down proteomics analysis revealed 563 unique proteins including 1,665 proteoforms generated by posttranslational modifications (PTMs), representing the largest microbial top-down dataset reported to date. We confirmed many previously recognized aspects of Salmonella biology and bacterial PTMs, and our analysis also revealed several additional biological insights. Of particular interest was differential utilization of the protein S-thiolation forms S-glutathionylation and S-cysteinylation in response to infection-like conditions versus basal conditions. This finding of a S-glutathionylation-to-S-cysteinylation switch in a condition-specific manner was corroborated by bottom-up proteomics data and further by changes in corresponding biosynthetic pathways under infection-like conditions and during actual infection of host cells. This differential utilization highlights underlying metabolic mechanisms that modulate changes in cellular signaling, and represents a report of S-cysteinylation in Gram-negative bacteria. Additionally, the functional relevance of these PTMs was supported by protein structure and gene deletion analyses. The demonstrated utility of our simple proteome-wide intact protein level measurement strategy for gaining biological insight should promote broader adoption and applications of top-down proteomics approaches.

TI Structural characterization of a unique marine animal family 7 cellobiohydrolase suggests a mechanism of cellulase salt tolerance SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE gribble; carbohydrate degrading enzymes ID PHANEROCHAETE-CHRYSOSPORIUM CEL7D; TRICHODERMA-REESEI; CRYSTAL-STRUCTURES; RECALCITRANT POLYSACCHARIDES; MOLECULAR CHARACTERIZATION; CELLOBIOSE DEHYDROGENASE; MELANOCARPUS-ALBOMYCES; TALAROMYCES-EMERSONII; GLYCOSYL HYDROLASES; DEGRADATION AB Nature uses a diversity of glycoside hydrolase (GH) enzymes to convert polysaccharides to sugars. As lignocellulosic biomass deconstruction for biofuel production remains costly, natural GH diversity offers a starting point for developing industrial enzymes, and fungal GH family 7 (GH7) cellobiohydrolases, in particular, provide significant hydrolytic potential in industrial mixtures. Recently, GH7 enzymes have been found in other kingdoms of life besides fungi, including in animals and protists. Here, we describe the in vivo spatial expression distribution, properties, and structure of a unique endogenous GH7 cellulase from an animal, the marine wood borer Limnoria quadripunctata (LqCel7B). RT-quantitative PCR and Western blot studies show that LqCel7B is expressed in the hepatopancreas and secreted into the gut for wood degradation. We produced recombinant LqCel7B, with which we demonstrate that LqCel7B is a cellobiohydrolase and obtained four high-resolution crystal structures. Based on a crystallographic and computational comparison of LqCel7B to the well-characterized Hypocrea jecorina GH7 cellobiohydrolase, LqCel7B exhibits an extended substrate-binding motif at the tunnel entrance, which may aid in substrate acquisition and processivity. Interestingly, LqCel7B exhibits striking surface charges relative to fungal GH7 enzymes, which likely results from evolution in marine environments. We demonstrate that LqCel7B stability and activity remain unchanged, or increase at high salt concentration, and that the L. quadripunctata GH mixture generally contains cellulolytic enzymes with highly acidic surface charge compared with enzymes derived from terrestrial microbes. Overall, this study suggests that marine cellulases offer significant potential for utilization in high-solids industrial biomass conversion processes.

TI Effects of Fulvic Acid on Uranium(VI) Sorption Kinetics SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID NATURAL ORGANIC-MATTER; HUMIC-ACID; METAL-IONS; COLUMN EXPERIMENTS; WATER INTERFACE; QUARTZ SAND; COMPLEXATION; ADSORPTION; SUBSTANCES; MIGRATION AB This study focuses on the effects of fulvic acid (FA) on uranium(VI) sorption kinetics to a silica sand. Using a tritium-labeled FA in batch experiments made it possible to investigate sorption rates over a wide range of environmentally relevant FA concentrations (0.37-23 mg L-1 TOC). Equilibrium speciation calculations were coupled with an evaluation of U(VI) and FA sorption rates based on characteristic times. This allowed us to suggest plausible sorption mechanisms as a function of solution conditions (e.g., pH, U(VI)/FA/surface site ratios). Our results indicate that U(VI) sorption onto silica sand can be either slower or faster in the presence of FA compared to a ligand-free system. This suggests a shift in the underlying mechanisms of FA effects on U(VI) sorption, from competitive sorption to influences of U(VI)-FA complexes, in the same system. Changes in metal sorption rates depend on the relative concentrations of metals, organic ligands, and mineral surface sites. Hence, these results elucidate the sometimes conflicting information in the literature about the influence of organic matter on metal sorption rates. Furthermore, they provide guidance for the selection of appropriate sorption equilibration times for experiments that are designed to determine metal distribution coefficients (K-d values) under equilibrium conditions.

TI Contribution of Nitrated Phenols to Wood Burning Brown Carbon Light Absorption in Detling, United Kingdom during Winter Time SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID POSITIVE MATRIX FACTORIZATION; IONIZATION MASS-SPECTROMETRY; PARTICULATE MATTER; ORGANIC AEROSOLS; BLACK CARBON; MEXICO-CITY; ATMOSPHERIC CHEMISTRY; COMBUSTION; AIR; PARTICLES AB We show for she first time quantitative online measurements of five nitrated phenol (NP) compounds in ambient air (nitrophenol C6H5NO3, methylnitrophenol C7H7NO3, nitrocatechol C6H5NO4, methylnitrocatechol C7H7NO4, and dinitrophenol C6H4N2O5) measured with a micro-orifice volatilization impactor (MOVI) high-resolution chemical ionization mass spectrometer in Detling, United Kingdom during January-February, 2012. NPs absorb radiation in the near-ultraviolet (UV) range of the electromagnetic spectrum and thus are potential components of poorly characterized light-absorbing organic matter ("brown carbon") which can affect the climate and air quality. Total NP concentrations varied between less than 1 and 98 ng m(-3), with a mean value of 20 ng m(-3). We conclude that NPs measured in Detling have a significant contribution from biomass burning with an estimated emission factor of 0.2 ng (ppb CO)(-1). Particle light absorption measurements by a seven-wavelength aethalometer in the near-UV (370 nm) and literature values of molecular absorption cross sections are used to estimate the contribution of NP to wood burning brown carbon UV light absorption. We show that these five NPs are potentially important contributors to absorption at 370 nm measured by an aethalometer and account for 4 +/- 2% of UV light absorption by brown carbon. They can thus affect atmospheric radiative transfer and photochemistry and with that climate and air quality.

TI In Situ Bioremediation of Uranium with Emulsified Vegetable Oil as the Electron Donor SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID HIGHLY CONTAMINATED AQUIFER; MICROBIAL COMMUNITIES; SUBMICROMOLAR LEVELS; U(VI) BIOREDUCTION; DISSOLVED-OXYGEN; EDIBLE OIL; NITRATE; REDUCTION; SEDIMENTS; GROUNDWATER AB A field test with a one-time emulsified vegetable oil (EVO) injection was conducted to assess the capacity of EVO to sustain uranium bioreduction in a high-permeability gravel layer with groundwater concentrations of (mM) U, 0.0055; Ca, 2.98; NO3-, 0.11; HCO3-, 5.07; and SO42-, 1.23. Comparison of bromide and EVO migration and distribution indicated that a majority of the injected EVO was retained in the subsurface from the injection wells to 50 m downgradient. Nitrate, uranium, and sulfate were sequentially removed from the groundwater within 1-2 weeks, accompanied by an increase in acetate, Mn, Fe, and methane concentrations. Due to the slow release and degradation of EVO with time, reducing conditions were sustained for approximately one year, and daily U discharge to a creek, located approximately 50 m from the injection wells, decreased by 80% within 100 days. Total U discharge was reduced by 50% over the one-year period. Reduction of U(VI) to U(IV) was confirmed by synchrotron analysis of recovered aquifer solids. Oxidants (e.g., dissolved oxygen, nitrate) flowing in from upgradient appeared to reoxidize and remobilize uranium after the EVO was exhausted as evidenced by a transient increase of U concentration above ambient values. Occasional (e.g., annual) EVO injection into a permeable Ca and bicarbonate-containing aquifer can sustain uranium bioreduction/immobilization and decrease U migration/discharge.

Despite its prevalence as a contaminant, the potential for vanadium bioremediation has not been widely studied. Injection of acetate (as a carbon source) directly into an aquifer to biostimulate contaminated sediments in Colorado, United States, resulted in prolonged removal of aqueous vanadium for a period of at least two years. To further investigate this process, we simultaneously added acetate and vanadate (V5+) to columns that were packed with aquifer sediment and inserted into groundwater wells installed on the Colorado River floodplain, This allowed evaluation of the microbial response to amendments in columns that received an influx of natural groundwater. Our results demonstrate the removal of up to 99% of the added V5+(aq) and suggest microbial mediation. Most probable number measurements demonstrate up to a 50-fold increase in numbers of V5+-reducing cells in vanadium-amended columns compared to controls. 16S rRNA gene sequencing indicates decreased diversity and selection for specific taxa in columns that received vanadate compared to those that did not. Overall, our results demonstrate that acetate amendment can be an effective strategy for V removal, and that V bioremediation may be a viable technology.

Therefore, analytical techniques that can (a) generate information about both organic and mineral phases simultaneously and (b) allow the examination of predetermined high-interest regions of the sample as opposed to conventional bulk analytical techniques are valuable. Laser desorption synchrotron postionization (synchrotron-LDPI) mass spectrometry is introduced as a novel analytical tool to characterize the molecular properties of organic compounds in mineral organic samples from terrestrial systems, and it is demonstrated that, when combined with secondary ion mass spectrometry (SIMS), it can provide complementary information on mineral composition. Mass spectrometry along a decomposition gradient in density fractions verifies the consistency of our results with bulk analytical techniques. We further demonstrate that, by changing laser and photoionization energies, variations in molecular stability of organic compounds associated with mineral surfaces can be determined. The combination of synchrotron-LDPI and SIMS shows that the energetic conditions involved in desorption and ionization of organic matter may be a greater, determinant of mass spectral signatures than the inherent molecular structure of the organic compounds investigated. The latter has implications for molecular models of natural organic matter that are based on mass spectrometric information.

The electrical conductivity of individual nanowire measured by four-probe scanning tunneling microscopy shows that F4-TCNQ molecules are effectively doped into P3HT by capillary force. The resistivity is tuned in the 0.1-10 Omega cm range by changing the F4-TCNQ concentration from 10 to 0.1 wt % and is 2-4 orders of magnitude smaller than that of the corresponding P3HT/F4-TNCQ thin film composites. The AAO template-assisted synthesis approach thus appears to be effective for high chemical doping and for improving the electrical conductivity of the molecular wires.

Interfacing of nanoparticles with active materials gives rise to the structures with unique multiple functionality. Superparamagnetic iron oxide nanoparticles particles SPION are widely employed in the biology and in developing of advanced medical technologies. Polymeric micelles offer the advantage of multifunctional carriers which can serve as delivery vehicles carrying nanoparticles, hydrophobic chemotherapeutics and other functional materials and molecules. Stimuli-responsive polymers are especially attractive since their properties can be modulated in a controlled manner. Here we report on multifunctional thermo-responsive poly(N-isopropylacrylamide-co-acrylamide)-block-poly(-caprolactone) random block copolymer micelles as magnetic hyperthermia-mediated payload release and imaging agents. The combination of copolymers, nanoparticles and doxorubicin drug was tailored the way that the loaded micelles were cable to respond to magnetic heating at physiologically-relevant temperatures. A surface functionalization of the micelles with the integrin beta 4 antibody and consequent interfacing of the resulting nanobio hybrid with squamous head and neck carcinoma cells which is known to specifically over-express the A9 antigen resulted in concentration of the micelles on the surface of cells. No inherent cytotoxicity was detected for the magnetic micelles without external stimuli application. Furthermore, SPION-loaded micelles demonstrate significant MRI contrast enhancement abilities.

TI The Observation of Highly Ordered Domains in Membranes with Cholesterol SO PLOS ONE LA English DT Article ID PROTEIN-PROTEIN INTERACTIONS; PHASE DPPC BILAYERS; X-RAY-SCATTERING; LIPID-BILAYERS; MOLECULAR SIMULATION; COLLECTIVE DYNAMICS; MAXIMUM SOLUBILITY; MODEL MEMBRANES; CELL BIOLOGY; RAFTS AB Rafts, or functional domains, are transient nano- or mesoscopic structures in the exoplasmic leaflet of the plasma membrane, and are thought to be essential for many cellular processes. Using neutron diffraction and computer modelling, we present evidence for the existence of highly ordered lipid domains in the cholesterol-rich (32.5 mol%) liquid-ordered (l(o)) phase of dipalmitoylphosphatidylcholine membranes. The liquid ordered phase in one-component lipid membranes has previously been thought to be a homogeneous phase. The presence of highly ordered lipid domains embedded in a disordered lipid matrix implies non-uniform distribution of cholesterol between the two phases. The experimental results are in excellent agreement with recent computer simulations of DPPC/cholesterol complexes [Meinhardt, Vink and Schmid (2013). Proc Natl Acad Sci USA 110(12): 4476-4481], which reported the existence of nanometer size l(o) domains in a liquid disordered lipid environment.

Here, the experimental conditions necessary for mode coexistence are explored. Mode coexistence is facilitated by the local field asymmetries induced by the spatially inhomogeneous Oersted field, which leads to a physical separation of the modes, and is further promoted by spin wave localization at reduced applied field angles. Finally, both simulation and experiment reveal a low frequency signal consistent with the intermodulation of two coexistent modes.

Upon Ni doping x, the nearly simultaneous tetragonal-to-orthorhombic structural (T-s) and antiferromagnetic (T-N) phase transitions in BaFe2As2 are gradually suppressed and separated, resulting in T-s > T-N with increasing x, as was previously observed. However, the temperature separation between T-s and T-N decreases with increasing x for x >= 0.065, tending toward a quantum bicritical point near optimal superconductivity at x approximate to 0.1. The zero-temperature transition is preempted by the formation of a secondary incommensurate magnetic phase in the region 0: 088 less than or similar to x less than or similar to 0.104, resulting in a finite value of T-N approximate to T-c + 10 K above the superconducting dome around x approximate to 0.1. Our results imply an avoided quantum critical point, which is expected to strongly influence the properties of both the normal and superconducting states.

TI Third Generation Photovoltaics based on Multiple Exciton Generation in Quantum Confined Semiconductors SO ACCOUNTS OF CHEMICAL RESEARCH LA English DT Review ID DOT SOLAR-CELLS; CARRIER MULTIPLICATION YIELDS; DETAILED BALANCE LIMIT; PBSE NANOCRYSTAL FILMS; MULTIEXCITON GENERATION; SILICON NANOCRYSTALS; IMPACT IONIZATION; EFFICIENCY; SOLIDS; CONVERSION AB Improving the primary photoconversion process in a photovoltaic cell by utilizing the excess energy that is otherwise lost as heat can lead to an increase in the overall power conversion efficiency (PCE). Semiconductor nanocrystals (NCs) with at least one dimension small enough to produce quantum confinement effects provide new ways of controlling energy flow not achievable in thin film or bulk semiconductors. Researchers have developed various strategies to incorporate these novel structures into suitable solar conversion systems. Some of these methods could increase the PCE past the Shockley - Queisser (SO) limit of similar to 33%, making them viable "third generation photovoltaic' (TGPV) cell architectures. Surpassing the SQ limit for single junction solar cells presents both a scientific and a technological challenge, and the use of semiconductor NCs to enhance the primary photoconversion process offers a promising potential solution. The NCs are synthesized via solution phase chemical reactions producing stable colloidal solutions, where the reaction conditions can be modified to produce a variety of shapes, compositions, and structures. The confinement of the semiconductor NC in one dimension produces quantum films, wells, or discs. Two-dimensional confinement leads to quantum wires or rods (QRs), and quantum dots (QDs) are three-dimensionally confined NCs. The process of multiple exciton generation (MEG) converts a high-energy photon into multiple electron hole pairs. Although many studies have demonstrated that MEG is enhanced in QDs compared with bulk semiconductors, these studies have either used ultrafast spectroscopy to measure the photon-to-exciton quantum yields (QYs) or theoretical calculations. Implementing MEG in a working solar cell has been an ongoing challenge. In this Account, we discuss the status of MEG research and strategies towards implementing MEG in working solar cells. Recently we showed an external quantum efficiency for photocurrent of greater than 100% (reaching 114%) at similar to 4E(g) in a PbSe QD solar cell. The internal quantum efficiency reached 130%. These results compare favorably with ultrafast transient spectroscopic measurements. Thus, we have shown that one of the tenets of the SQ limit, that photons only produce one electron - hole pair at the electrodes of a solar cell, can be overcome. Further challenges include increasing the MEG efficiency and improving the QD device structure and operation.

TI Carrier Multiplication in Semiconductor Nanocrystals: Influence of Size, Shape, and Composition SO ACCOUNTS OF CHEMICAL RESEARCH LA English DT Review ID MULTIPLE EXCITON GENERATION; PBSE QUANTUM DOTS; SOLAR-CELLS; AUGER RECOMBINATION; EFFICIENCY; ELECTRON; RELAXATION; DEPENDENCE; NANORODS; STATES AB During carrier multiplication (CM), also known as multiexciton generation (MEG), absorption of a single photon produces multiple electron-hole pairs, or excitons. This process can appreciably increase the efficency of photoconversion, which is especially beneficial in photocatalysis and photovoltaics. This Account reviews recent progress in understanding the CM process in semiconductor nanocrystals (NCs), motivated by the challenge researchers face to quickly identify candidate nanomaterials with enhanced CM. We present a possible solution to this problem by showing that, using measured biexciton Auger lifetimes and intraband relaxation rates as surrogates for, respectively, CM time constants and non-CM energy-loss rates, we can predict relative changes in CM yields as a function of composition. Indeed, by studying PbS, PbSe, and PbTe NCs of a variety of sties we determine that the significant difference in CM yields for these compounds comes from the dissimilarities in their non-CM relaxation channels, i.e., the processes that compete with CM. This finding is likely general, as previous observations of a material-independent, "universal" volume-scaling of Auger lifetimes suggest that the timescale of the CM process itself is only weakly affected by NC composition. We further explore the role of nanostructure shape in the CM process. We observe that a moderate elongation (aspect ratio of 6-7) of PbSe NCs can cause up to an approximately two-fold increase in the multiexciton yield compared to spherical nanoparticles. The increased Auger lifetimes and improved charge transport properties generally assodated with elongated nanostructures suggest that lead chalcogenide nanorods are a promising system for testing CM concepts in practical photovoltaics. Historically, experimental considerations have been an important factor influencing CM studies. To this end, we discuss the role of NC photocharging in CM measurements. Photodiarging can distort multiexciton dynamics, leading to erroneous estimations of the CM yield. Here, we show that in addition to distorting time-resolved CM signals, photocharging also creates spectral signatures that mimic CM. This re-emphasizes the importance of a careful analysis of the potential effect of charged species in both optical and photocurrent-based measurements of this process.

This process, called singlet fission, is one possible "exciton multiplication" scheme that could be useful in a variety of photovoltaic device designs from dye-sensitized solar cells to solar cell bilayers to bulk heterojunctions. For such applications to be possible, however, singlet fission must occur with near perfect efficiency in compounds that also have other requisite properties such as strong visible light absorption and photostability. Many recent investigations of singlet fission have focused on crystalline polyacenes, which have been known for some time to undergo singlet fission. While these materials have promise, limitations in stability, cost, and performance may hinder practical application of polyacene solar cells, while their complex photophysics may limit our fundamental understanding of singlet fission in crystalline polyacenes. In this Account, we describe rationally designed singlet fission chromophores whose excited state dynamics should be fairly simple and whose coupling can be well controlled through the formation of covalent dimers, aggregates, or polycrystalline films. In principle, investigations of these chromophores should provide the dearest connection to theoretical concepts explaining how an excited state evolves from a singlet (Si) into two triplets (IT). Realizing the promise of efficient singlet fission rests with two tasks: (i) producing an ideal molecular energy level structure and (ii) inducing the correct type and strength of chromophore coupling. In this Account, we offer theoretical guidance for achieving 0) and consider more extensively recent results aimed at (ii). For (i), theoretical guidance suggests that, in addition to alternant hydrocarbons like tetracene and pentacene, biradicals (i.e., molecules with two independent radical centers) may also be used as the basis for designing chromophores with low-lying triplet states such that the energy relationship 2E(T-1) <= E(S-1) is satisfied. Although molecules that do not fulfill this condition can also exhibit singlet fission from a higher lying or vibrationally excited singlet state, fast relaxation processes will likely reduce the singlet fission yield and complicate determination of the singlet fission mechanism. For (ii), once an appropriate chromophore has been chosen, the task of coupling two or more of them together must be done carefully. We discuss three pathways by which a dimer could undergo singlet fission: (1) A direct route in which slipped cofacial stacking is favorable under certain conditions. Cofacial stacking is common in molecular crystals, and it is likely not a coincidence that recent reports of efficient singlet fission involve slipped-stacked molecules in polycrystalline thin films. (2) A mediated route in which SI interacts with (TT) through a virtual radical cation/anion state, which may be important in some situations. (3) A two-step route (i.e., through a real charge transfer intermediate) which others have suggested theoretically. We present data on 1,3-diphenylisobenzofuran (DPIBF) dimers that are consistent with this pathway. Finally, we review potential solar photoconversion efficiency gains utilizing singlet fission in several contexts.

However, this general rule breaks down in a few organic semiconductors, such as pentacene and tetracene, where one photon absorption may result in two electron hole pairs. This process, where a singlet exciton transforms to two triplet excitons, can have quantum yields as high as 200%. Singlet fission may be useful to solar cell technologies to increase the power conversion efficiency beyond the so-called Shockley-Queisser limit. Through time-resolved two-photon photo-emission (TR-2PPE) spectroscopy in crystalline pentacene and tetracene, our lab has recently provided the first spectroscopic signatures in singlet fission of a critical intermediate known as the multiexciton state (also called a correlated triplet pair). More importantly, we found that population of the multiexciton state rises at the same time as the singlet state on the ultrafast time scale upon photoexcitation. This observation does not fit with the traditional view of singlet fission involving the incoherent conversion of a singlet to a triplet pair. However, it provides an experimental foundation for a quantum coherent mechanism in which the electronic coupling creates a quantum superposition of the singlet and the multiexciton state immediately after optical excitation. In this Account, we review key experimental findings from TR-2PPE experiments and present a theoretical analysis of the quantum coherent mechanism based on electronic structural and density matrix calculations for crystalline tetracene lattices. Using multistate density functional theory, we find that the direct electronic coupling between singlet and multiexciton states is too weak to explain the experimental observation. Instead, indirect coupling via charge transfer intermediate states is two orders of magnitude stronger, and dominates the dynamics for ultrafast multiexciton formation. Density matrix calculation for the crystalline tetracene lattice satisfactorily accounts for the experimental observations. It also reveals the critical roles of the charge transfer states and the high dephasing rates in ensuring the ultrafast formation of multiexciton states. In addition, we address the origins of microscopic relaxation and dephasing rates, and adopt these rates in a quantum master equation description. We show the need to take the theoretical effort one step further in the near future by combining high-level electronic structure calculations with accurate quantum relaxation dynamics for large systems.

Scientists might exploit singlet fission to its full potential by first understanding the underlying mechanism of this quantum mechanical process. The pursuit of this fundamental mechanism has recently benefited from the development and application of new correlated wave function methods. These-methods called restricted active space spin flip-can capture the most important electron interactions in molecular materials, such as acene crystals, at low computational cost It is unrealistic to use previous wave function methods due to the excessive computational cost involved in simulating realistic molecular structures at a meaningful level of electron correlation. In this Account, we describe how we use these techniques to compute single exciton and multiple exciton excited states in tetracene and pentacene crystals in order to understand how a single exciton generated from photon absorption undergoes fission to generate two triplets. Our studies indicate that an adiabatic charge transfer intermediate is unlikely to contribute significantly to the fission process because it lies too high in energy. Instead, we propose a new mechanism that involves the direct coupling of an optically allowed single exciton to an optically dark multiexciton. This coupling is facilitated by intermolecular motion of two acene monomers that drives nonadiabatic population transfer between the two states. This transfer occurs in the limit of near degeneracies between adiabatic states where the Born-Oppenheimer approximation of fixed nuclei is no longer valid. Existing theories for singlet fission have not considered this type of coupling between states and, therefore, cannot describe this mechanism. The direct mechanism through intermolecular motion describes many experimentally observed characteristics of these materials, such as the ultrafast time scale of photobleaching and triplet generation during singlet fission in pentacene. We believe this newly discovered mechanism provides fundamental insight to guide the creation of new solar materials that exhibit high efficiencies through multiple charge generation.

Since it removes most of the approximations and complexities in the two conventional theories, the FCWDT is almost rigorous yet simple and, in principle, can be used to compute scattering of electromagnetic waves from any kinds of periodic (nonmagnetic) structures, including x-ray diffraction from crystals and soft x-ray and light diffraction from periodic multilayers, gratings, and photonic crystals.

Using the algorithm to study the quantum Ising model in 2D (both in its disordered phase and near criticality), we confirm the existence of an area law for the entanglement entropy and show that near criticality there is an additive piece scaling as c(eff) log(N)/6 with c(eff) approximate to 1. Studying the entanglement spectrum, we show that entanglement gap scaling can be used to detect the critical point of the 2D model. When short-range (area law) entanglement dominates we find (numerically and perturbatively) that this spectrum reflects the energy spectrum of a single quantum Ising chain. C1 [James, Andrew J.

TI Magnetism and structural distortions in uranium sulfide under pressure SO PHYSICAL REVIEW B LA English DT Article ID GENERALIZED GRADIENT APPROXIMATION; X-RAY; MONOCHALCOGENIDES US; TRANSPORT-PROPERTIES; CIRCULAR-DICHROISM; ACTINIDE COMPOUNDS; DELTA-PU; UTE; DIFFRACTION; EXCITATION AB Uranium sulfide belongs to a class of uranium monochalcogenides that crystallize in the rocksalt structure and exhibit ferromagnetism at low temperature. The magnetism is believed to play a role in the low-temperature rhombohedral distortion, possibly due to its large magnetic anisotropy. We have performed electrical and structural characterization along with density-functional theory calculations as functions of pressure to help understand the interplay between structure and magnetism in US. Theoretical calculations suggest that ferromagnetic order is responsible for the small distortion at ambient pressure and low temperature. Under pressure, the Curie temperature is reduced monotonically until it discontinuously disappears near a pressure-induced deformation of the crystal structure. This high-pressure distortion is identical to the one correlated with the onset of magnetic order, but with a larger change in the cell angle. Calculations imply a reduction in the electronic band energy as the driving force for the pressure-induced structure, but the loss of magnetic order associated with this distortion remains a mystery. The high-pressure electronic phase diagram may shed light on the magnetostructural free energy landscape of US. C1 [Jeffries, J. R.; Soederlind, P.; Cynn, H.; Landa, A.; Evans, W. J.; Weir, S.

TI Linewidth of the electromagnetic radiation from Josephson junctions near cavity resonances SO PHYSICAL REVIEW B LA English DT Article ID COLLECTIVE MODE; SUPERCONDUCTORS; EMISSION; ARRAYS AB The powerful terahertz emission from intrinsic Josephson junctions in high-T-c cuprate superconductors has been detected recently. The synchronization of different junctions is enhanced by excitation of the geometrical cavity resonance. A key characteristic of the radiation is its linewidth. In this work, we study the intrinsic linewidth of the radiation near the internal cavity resonance. Surprisingly, this problem was never considered before, neither for a single Josephson junction nor for a stack of the intrinsic Josephson junctions realized in cuprate superconductors. The linewidth appears due to the slow phase diffusion, which is determined by the dissipation and amplitude of the noise. We found that both these parameters are resonantly enhanced when the cavity mode is excited but enhancement of the dissipation dominates leading to the net suppression of diffusion and dramatic narrowing of the linewidth. The line shape changes from Lorentzian to Gaussian when either the Josephson frequency is shifted away from the resonance or the temperature is increased.

We explore a model LaGaO3(001)//MgAl2O4(001) heterostructure with nominally negatively charged interfaces using first-principles methods and a Poisson-Boltzmann equation. We find that charge compensation by oxygen vacancies with quadratically decaying concentration away from the interface is more favorable than electronic redistribution. These vacancies have a potential to enhance ionic conductivity along the interfaces. C1 [Rebola, Alejandro; Oeguet, Serdar] Univ Illinois, Dept Phys, Chicago, IL 60607 USA.

TI Signatures of quantum criticality in the thermopower of Ba(Fe1-xCox)(2)As-2 SO PHYSICAL REVIEW B LA English DT Article ID IRON ARSENIDE SUPERCONDUCTOR; FERMI-LIQUID BEHAVIOR; CUPRATE SUPERCONDUCTORS; CRITICAL-POINT; RESISTIVITY; TEMPERATURE; SURFACE; BAFE2(AS1-XPX)(2); INSTABILITY; TRANSITION AB We demonstrate that the thermopower (S) can be used to probe the spin fluctuations (SFs) in proximity to the quantum critical point (QCP) in Fe-based superconductors. The sensitivity of S to the entropy of charge carriers allows us to observe an increase of S/T in Ba(Fe1-x Co-x)(2)As-2 close to the spin-density-wave (SDW) QCP. This behavior is due to the coupling of low-energy conduction electrons to two-dimensional SFs, similar to heavy-fermion systems. The low-temperature enhancement of S/T in the Co substitution range 0.02 < x < 0.1 is bordered by two Lifshitz transitions, and it corresponds to the superconducting region, where a similarity between the electron and nonreconstructed hole pockets exists. The maximal S/T is observed in proximity to the commensurate-to-incommensurate SDW transition, for critical x(c) approximate to 0.05, close to the highest superconducting T-c. This analysis indicates that low-T thermopower is influenced by critical spin fluctuations which are important for the superconducting mechanism.

TI Heavily doped n-type PbSe and PbS nanocrystals using ground-state charge transfer from cobaltocene SO SCIENTIFIC REPORTS LA English DT Article ID FIELD-EFFECT TRANSISTORS; SEMICONDUCTOR NANOCRYSTALS; QUANTUM DOTS; ELECTRONIC-STRUCTURE; INFRARED-EMISSION; FILMS; INJECTION; TRANSPORT; SOLIDS; BRIGHT AB Colloidal nanocrystals (NCs) of lead chalcogenides are a promising class of tunable infrared materials for applications in devices such as photodetectors and solar cells. Such devices typically employ electronic materials in which charge carrier concentrations are manipulated through "doping;" however, persistent electronic doping of these NCs remains a challenge. Here, we demonstrate that heavily doped n-type PbSe and PbS NCs can be realized utilizing ground-state electron transfer from cobaltocene. This allows injecting up to eight electrons perNCinto the band-edge state and maintaining the doping level for at least a month at room temperature. Doping is confirmed by inter- and intra-band optical absorption, as well as by carrier dynamics. Finally, FET measurements of doped NC films and the demonstration of a p-n diode provide additional evidence that the developed doping procedure allows for persistent incorporation of electrons into the quantum-confined NC states.

TI Inelastic X-ray Scattering of a Transition-Metal Complex (FeCl4-): Vibrational Spectroscopy for All Normal Modes SO INORGANIC CHEMISTRY LA English DT Article ID DYNAMICS AB The tetraethylammonium salt of the transition-metal complex FeCl4- has been examined using inelastic X-ray scattering (IXS) with 1.5 meV resolution (12 cm(-1)) at 21.747 keV. This sample serves as a feasibility test for more elaborate transition-metal complexes. The IXS spectra were compared with previously recorded IR, Raman, and nuclear resonant vibrational spectroscopy (NRVS) spectra, revealing the same normal modes but with less strict selection rules. Calculations with a previously derived Urey-Bradley force field were used to simulate the expected Q and orientation dependence of the IXS intensities. The relative merits of IXS, compared to other photon-based vibrational spectroscopies such as NRVS, Raman, and IR, are discussed.

TI In Situ Structural Characterization of Ferric Iron Dimers in Aqueous Solutions: Identification of mu-Oxo Species SO INORGANIC CHEMISTRY LA English DT Article ID RAY-ABSORPTION-SPECTROSCOPY; 2ND HYDRATION SHELL; FINE-STRUCTURE; MOSSBAUER-SPECTROSCOPY; ELECTRONIC-STRUCTURE; MOLECULAR-STRUCTURE; MAGNETIC-PROPERTIES; METAL-COMPLEXES; WATER-EXCHANGE; IRON(III) AB The structure of ferric iron (Fe3+) dimers in aqueous solutions has long been debated. In this work, we have determined the dimer structure in situ in aqueous solutions using extended X-ray absorption fine structure (EXAFS) spectroscopy. An Fe K-edge EXAFS analysis of 0.2 M ferric nitrate solutions at pH 1.28-1.81 identified a Fe-Fe distance at similar to 3.6 angstrom, strongly indicating that the dimers take the mu-oxo form. The EXAFS analysis also indicates two short Fe-O bonds at similar to 1.80 angstrom and ten long Fe-O bonds at similar to 2.08 angstrom, consistent with the mu-oxo dimer structure. The scattering from the Fe Fe paths interferes destructively with that from paths belonging to Fe(OH2)(6)(3+) monomers that coexist with the dimers, leading to a less apparent Fe shell in the EXAFS Fourier transform. This might be a reason why the characteristic Fe Fe distance was not detected in previous EXAFS studies. The existence of mu-oxo dimers is further confirmed by Mossbauer analyses of analogous quick frozen solutions. This work also explores the electronic structure and the relative stability of the mu-oxo dimer in a comparison to the dihydroxo dimer using density function theory (DFT) calculations. The identification of such dimers in aqueous solutions has important implications for iron (bio)inorganic chemistry and geochemistry, such as understanding the formation mechanisms of Fe oxyhydroxides at molecular scale.

TI Crystal Structure and Local Structure of Mg2-xPrxNi4 (x=0.6 and 1.0) Deuteride Using in Situ Neutron Total Scattering SO INORGANIC CHEMISTRY LA English DT Article ID X-RAY-DIFFRACTION; INITIAL ACTIVATION PROCESS; TOTAL-ENERGY CALCULATIONS; AUGMENTED-WAVE METHOD; HYDROGENATION PROPERTIES; INTERMETALLIC COMPOUNDS; AB-INITIO; PSEUDO-AB(2) COMPOUNDS; POWDER DIFFRACTION; BASIS-SET AB We studied crystal structure and local structure of Mg2-xPrxNi4 (x = 0.6 and 1.0) and their deuterides using in situ neutron total scattering and first-principles calculations. The total scattering data were analyzed using Rietveld refinement and pair distribution function analysis (PDF). The crystal structure of Mg2-xPrxNi4 before deuterium absorption was C15b in space group F (4) over bar 3m. No difference between the crystal and local (PDF) structures was observed. The crystal structure of Mg1.0Pr1.0Ni4D similar to 4 was found to be orthorhombic in space group Pmn2(1), with three deuterium occupation sites: PrNi3 and two types of bipyramidal Pr2MgNi2 that have a plane of symmetry composed of MgNi2. There is no significant difference between the crystal structure and the local structure of Mg10Pr1.0Ni4D similar to 4. On the other hand, the average crystal structure of the Mg-rich Mg1.4Pr0.6Ni4D similar to 3.6 was C15b with two deuterium occupation sites: PrNi3 and MgPrNi2 suggesting that the deuterium occupation shifts away from the Pr2MgNi2 bipyramid. First-principles relaxed structures also showed the shift of the hydrogen occupation site toward the Pr atom of the bipyramid, when induced by Mg substitution for the opposing Pr, resulting in hydrogen occupation in the MgPrNi2 tetrahedral site. The PDF pattern of Mg1.4Pr0.6Ni4D similar to 3.6 cannot be refined below 7.2 angstrom in atomic distances using the C15b structure which was obtained from Rietveld refinement but can be done using an orthorhombic structure. It suggests that Mg1.4Pr0.6Ni4D similar to 3.6 was locally distorted to the orthorhombic.

TI Photoconductivity in the Chalcohalide Semiconductor, SbSeI: a New Candidate for Hard Radiation Detection SO INORGANIC CHEMISTRY LA English DT Article ID V(A)-VI(A)-VII(A) SINGLE-CRYSTALS; UP-CONVERSION LUMINESCENCE; ION-EXCHANGE PROPERTIES; GAMMA-RAY DETECTION; OPTICAL-PROPERTIES; X-RAY; PHASE-TRANSITIONS; ROOM-TEMPERATURE; ANTIMONY; GLASSES AB We investigated an antimony chalcohalide compound, SbSeI, as a potential semiconductor material for X-ray and gamma-ray detection. SbSeI has a wide band gap of 1.70 eV with a density of 5.80 g/cm(3), and it crystallizes in the orthorhombic Pnma space group with a one-dimensional chain structure comprised of infinite zigzag chains of dimers [Sb2Se4I8](n) running along the crystallographic b axis. In this study, we investigate conditions for vertical Bridgman crystal growth using combinations of the peak temperature and temperature gradients as well as translation rate set in a three-zone furnace. SbSeI samples grown at 495 degrees C peak temperature and 19 degrees C/cm temperature gradient with 2.5 mm/h translation rate produced a single phase of columnar needlelike crystals aligned along the translational direction of the growth. The ingot sample exhibited an n-type semiconductor with resistivity of similar to 10(8) Omega.cm. Photoconductivity measurements on these specimens allowed us to determine mobility-lifetime (mu tau) products for electron and hole carriers that were found to be of similar order of magnitude (similar to 10(-4) cm(2)/V). Further, the SbSeI ingot with well-aligned, one-dimensional columnar needlelike crystals shows an appreciable response of Ag K alpha X-ray.

Calorimetry measurements then demonstrated that relaxation of the thermally trapped phase was concurrent with two separate processes, not previously detected as such. Determination of the photogenerated HS structure revealed a new metastable HS state of the system, much closer structurally to the low-spin phase than the thermally trapped one. This difference is proposed as the root of the disparate kinetic behavior, which is proposed to require two processes in the case of the structurally more complex thermally trapped state. Therefore, light irradiation is shown as a mechanism to decouple effectively the structural and magnetic phase transitions that occur in I during the course of its spin crossover.

Synthesized from the reaction of Cu in a molten alkali metal/polysulfide flux, the compound crystallizes in monoclinic space group C2/m with a = 16.5363(7) angstrom, b = 5.5374(5) degrees, c = 10.3717(10) angstrom, beta = 98.535(8)degrees. The Na+ Ba-2(+2) [Cu3+S3]S-3-(2)2- crystal structure contains layers of edge sharing CuS4 tetrahedra and sheets of S-2(2-) dimers. These layers are separated by mixed Ba/Na cation layers. The conductivity of the single crystals of NaBa2Cu3S5 is similar to 450 S cm(-1) at room temperature, and increasing conductivity with decreasing temperature is observed, indicating metallic behavior despite the optical band gap of 0.45 eV. A small positive thermopower (45-55 mu V K-1 from 300 K to 500 K) and Hall effect measurements also confirm p-type conductivity with carrier concentration at 200 K of similar to 1.6 X 10(21) cm(-3) and a hole mobility of similar to 2 cm(2) V-1 s(-1). NaBa2Cu3S5 exhibits temperature-independent Pauli paramagnetism.

TI DNA-programmed mesoscopic architecture SO PHYSICAL REVIEW E LA English DT Article ID BUILDING-BLOCKS; CRYSTALLIZATION; DESIGN; NANOPARTICLES; HYBRIDIZATION; CLUSTERS; CRYSTALS; COLLOIDS AB We study the problem of the self-assembly of nanoparticles (NPs) into finite mesoscopic structures with a programmed local morphology and complex overall shape. Our proposed building blocks are NPs that are directionally functionalized with DNA. The combination of directionality and selectivity of interactions allows one to avoid unwanted metastable configurations, which have been shown to lead to slow self-assembly kinetics even in much simpler systems. With numerical simulations, we show that a variety of target mesoscopic objects can be designed and self-assembled in near perfect yield. They include cubes, pyramids, boxes, and even an Empire State Building model. We summarize our findings with a set of design strategies that leads to the successful self-assembly of a wide range of mesostructures.

Notably, InAs and WSe2 are two materials with completely different crystal structures, which heterojunction is inconceivable with traditional epitaxial growth techniques. Clear rectification from the n-InAs/p-WSe2 junction (forward/reverse current ratio >10(6)) is observed. A low reverse bias current <10(-12) A/mu m(2) and ideality factor of similar to 1.1 were achieved, suggesting near-ideal electrically active interfaces. (C) 2013 AIP Publishing LLC.

TI Large antisymmetric magnetoresistance across chemically etched GaMnAs nanoconstrictions SO APPLIED PHYSICS LETTERS LA English DT Article ID CURIE-TEMPERATURE; TRANSPORT; MN)AS; (GA AB We report the observation of a highly antisymmetric magnetoresistance in GaMnAs specimens with lateral nano-constrictions. The experiments were carried out on samples with an in-plane easy axis of magnetization, in in-plane applied magnetic field. We attribute this behavior to the formation of isolated nano-sized islands at the nano-constrictions, whose magnetization can undergo out-of-plane reorientation during switching. The change in resistance is up to 50%, which cannot be explained by the normal anisotropic magnetoresistance in GaMnAs. We propose tunneling anisotropic magnetoresistance as the most likely mechanism for this effect. (C) 2013 AIP Publishing LLC. C1 [Eid, K. F.] Miami Univ, Dept Phys, Oxford, OH 45056 USA. [Ocola, L.

The 0.5 mm-thick PMN-PT substrate contains a 10 mu m-wide, 60 nm-thick Ni/Pt electron-permeable observation region. Stress from the substrate creates magnetoelastic anisotropy of up to 4 kJ m(-3) in the nickel film resulting in reversible magnetization rotation as well as non-reversible domain wall jumps (i.e., Barkhausen jumps). The observed magnetization of the film is directly related to the local strain gradient as computed by the finite element method, providing strong evidence of the effectiveness of the strain-mediated magnetoelectric approach for device applications.

TI Magnetic properties of gadolinium substituted Bi2Te3 thin films SO APPLIED PHYSICS LETTERS LA English DT Article ID TOPOLOGICAL INSULATORS; WEAK ANTILOCALIZATION; SURFACE; NANORIBBONS AB Thin film GdBiTe3 has been proposed as a candidate material in which to observe the quantum anomalous Hall effect. As a thermal non-equilibrium deposition method, molecular beam epitaxy (MBE) has the ability to incorporate large amounts of Gd into Bi2Te3 crystal structures. High-quality rhombohedral (GdxBi1-x)(2)Te-3 films with substitutional Gd concentrations of x <= 0.4 were grown by MBE. Angle-resolved photoemission spectroscopy shows that the topological surface state remains intact up to the highest Gd concentration. Magnetoresistance measurements show weak antilocalization, indicating strong spin orbit interaction. Magnetometry reveals that the films are paramagnetic with a magnetic moment of 6.93 mu(B) per Gd3+ ion. (C) 2013 AIP Publishing LLC.

Resulting phases were single crystalline solid solutions for all compositions with significant defects present. The as-deposited clusters formed in a bcc structure for Fe content >65 at.% and in a fcc structure for Fe <65 at.%. Lattice parameters were expanded beyond rule-of-mixture estimates. The lattice expansion is explained by an analytical self-interstitial model. All clusters were ferromagnetic, although the fcc structures showed low magnetization. The low magnetizations are thought to arise from antiferromagnetic cores with uncompensated ferromagnetic surface spins. (C) 2013 AIP Publishing LLC. C1 [Mukherjee, P.; Shield, J.

Based on velocity data from multiple samples of differing thicknesses, a technique based on backward minimization is presented that allows the determination of material response along an elevated isentrope through the shock state.

TI Robust wedge demonstration to optical negative index metamaterials SO APPLIED PHYSICS LETTERS LA English DT Article ID REFRACTIVE-INDEX AB A robust wedge setup is proposed to unambiguously demonstrate negative refraction for negative index metamaterials. We applied our setup to several optical metamaterials from the literature and distinctly observed the phenomena of negative refraction. This further consolidates the reported negative-index property. It is found that there generally exists a lateral shift for the outgoing beam through the wedge. We derived a simple expression for calculating this beam shift and interestingly, it provides us a strategy to quantitatively estimate the loss of the wedge material (Im[n]). Additionally, we offered a design of metamaterials, compatible with nano-imprinting-lithography, showing negative refractive index in the visible regime (around yellow-light wavelengths). The multi-layer-system retrieval was utilized to extract the effective refractive index of the metamaterial. It was also intuitively characterized through our wedge setup to demonstrate corresponding phenomena of refraction. (C) 2013 AIP Publishing LLC.

TI Doping dependence of self-diffusion in germanium and the charge states of vacancies SO APPLIED PHYSICS LETTERS LA English DT Article ID GE; ACTIVATION AB Self-diffusion in boron-doped germanium has been studied at temperatures between 526 and 749 degrees C with secondary ion mass spectrometry. Self-diffusion under acceptor doping is retarded compared to intrinsic conditions. This demonstrates the contribution of charged vacancies in self-diffusion. Taking into account the dominance of doubly negatively charged vacancies under donor doping, the doping dependence of self-diffusion is best described with an inverse level ordering for singly and doubly negatively charged vacancies for all doping conditions. The level ordering explains the dominance of doubly charged vacancies under donor doping and their decreasing contribution with increasing acceptor doping until neutral vacancies mediate self-diffusion.

TI Optical phonons and the soft mode in 2H-NbSe2 SO PHYSICAL REVIEW B LA English DT Article ID DENSITY-WAVE TRANSITIONS; NEUTRON-SCATTERING; SUPERCONDUCTIVITY; DICHALCOGENIDES; 2H-TASE2 AB We present an investigation of the lattice dynamics of the charge density wave (CDW) compound 2H-NbSe2. We analyze the precise nature of the wave vector-dependent electron-phonon coupling (EPC) and derive the bare dispersion of the CDW soft phonon mode using inelastic x-ray scattering combined with ab initio calculations. Experimentally, phonon modes along the Gamma - M line, i.e., q=(h, 0,0), with 0 <= h <= 0.5 and the same longitudinal symmetry (Sigma(1)) as the CDW soft mode, were investigated up to 32 meV. In agreement with our calculations, we observe significant EPC in the optic modes at h <= 0.2. We analyze the EPC in the optic, as well as acoustic, mode and show that the q dependences stem from scattering processes between two bands at the Fermi surface that both have a Nb 4d character. Finally, we demonstrate that the soft mode dispersion at T=33 K (=T-CDW) can be well described on the basis of a strongly q-dependent EPC matrix element and an acousticlike bare phonon dispersion in agreement with observations near room temperature.

CA Belle Collaboration TI Study of e(+)e(-) -> pi(+)pi(-) J/psi and Observation of a Charged Charmoniumlike State at Belle SO PHYSICAL REVIEW LETTERS LA English DT Article ID CROSS-SECTION; ANNIHILATION AB The cross section for e(+)e(-) -> pi(+)pi(-) J/psi between 3.8 and 5.5 GeV is measured with a 967 fb(-1) data sample collected by the Belle detector at or near the Upsilon(nS) (n = 1, 2, . . . , 5) resonances. The Y(4260) state is observed, and its resonance parameters are determined. In addition, an excess of pi(+)pi(-) J/psi production around 4 GeV is observed. This feature can be described by a Breit-Wigner parametrization with properties that are consistent with the Y(4008) state that was previously reported by Belle. In a study of Y(4260) -> pi(+)pi(-) J/psi decays, a structure is observed in the M(pi(+/-) J/psi) mass spectrum with 5.2 sigma significance, with mass M = (3894.5 +/- 6.6 +/- 4.5) MeV/c(2) and width Gamma = (63 +/- 24 +/- 26) MeV/c(2), where the errors are statistical and systematic, respectively. This structure can be interpreted as a new charged charmoniumlike state. C1 [Schnell, G.; Van Hulse, C.] Univ Basque Country UPV EHU, Bilbao 48080, Spain.

The modes soften close to the critical field of 18.8 T along the [001] (pseudocubic) axis, where the cycloidal structure changes to the homogeneous canted antiferromagnetic state and a new strong mode with linear field dependence appears that persists at least up to 31 T. A microscopic model that includes two Dzyaloshinskii-Moriya interactions and easy-axis anisotropy describes closely both the zero-field spectroscopic modes as well as their splitting and evolution in a magnetic field. The good agreement of theory with experiment suggests that the proposed model provides the foundation for future technological applications of this multiferroic material.

TI Contrasting effects of Deadend1 (Dnd1) gain and loss of function mutations on allelic inheritance, testicular cancer, and intestinal polyposis SO BMC GENETICS LA English DT Article DE Testicular cancer; Allelic segregation; Intestinal neoplasia; DND1 ID GERM-CELL TUMORS; RNA-BINDING PROTEIN; MESSENGER-RNA; EMBRYONIC VIABILITY; GENE-EXPRESSION; SUSCEPTIBILITY; ZEBRAFISH; MICE; DMRT1; END AB Background: Certain mutations in the Deadend1 (Dnd1) gene are the most potent modifiers of testicular germ cell tumor (TGCT) susceptibility in mice and rats. In the 129 family of mice, the Dnd1(Ter) mutation significantly increases occurrence of TGCT-affected males. To test the hypothesis that he Dnd1(Ter) allele is a loss-of-function mutation; we characterized the consequences of a genetically-engineered loss-of-function mutation in mice, and compared these results with those for Dnd1(Ter). Results: We found that intercrossing Dnd1(+/KO) heterozygotes to generate a complete loss-of-function led to absence of Dnd1(KO/KO) homozygotes and significantly reduced numbers of Dnd1(+/KO) heterozygotes. Further crosses showed that Dnd1(Ter) partially rescues loss of Dnd1(KO) mice. We also found that loss of a single copy of Dnd1 in Dnd1(KO/+) heterozygotes did not affect baseline occurrence of TGCT-affected males and that Dnd1(Ter) increased TGCT risk regardless whether the alternative allele was loss-of-function (Dnd1(KO)) or wild-type (Dnd1(+)). Finally, we found that the action of Dnd1(Ter) was not limited to testicular cancer, but also significantly increased polyp number and burden in the Apc(+/Min) model of intestinal polyposis. Conclusion: These results show that Dnd1 is essential for normal allelic inheritance and that Dnd1(Ter) has a novel combination of functions that significantly increase risk for both testicular and intestinal cancer.

TI Incommensurability and spin dynamics in the low-temperature phases of Ni3V2O8 SO PHYSICAL REVIEW B LA English DT Article ID FERROELECTRICITY; MULTIFERROICS; DIFFRACTION AB Magnetic order and low-energy spin dynamics in the zero field ground state of Ni3V2O8 are revealed in elastic and inelastic neutron scattering experiments. Neutron diffraction shows that below T = 2.3 K the Ni2+ moments (spin S = 1) order in a cycloid pattern with incommensurate wave vector k(ICM) = (0,1, tau), where tau = 0.4030 +/- 0.0004, which is superimposed on a commensurate antiferromagnetic spin arrangement with k(CM) = (0,0,0). Three spin wave modes are discerned below E similar to 3 meV in inelastic measurements and qualitatively described by a model Hamiltonian that involves near neighbor exchange, local anisotropy, and a small biquadratic coupling between the spine and cross-tie sites. Results from both elastic and inelastic scattering experiments suggest that the two sublattices on spine and cross-tie sites are largely decoupled. C1 [Ehlers, G.; Podlesnyak, A. A.; Hahn, S.

When a conduction electron moves around the skyrmion, its spin is fully polarized by the spin texture and acquires a quantized phase; thus, the skyrmion yields an emergent electrodynamics that in turn determines skyrmion motion and gives rise to a finite Hall angle. As topological excitations, skyrmions behave as particles. In this paper we derive the equation of motion for skyrmions as rigid point particles from a microscopic continuum model and obtain the short-range interaction between skyrmions and the interaction between skyrmions and defects. Skyrmions also experience a Magnus force perpendicular to their velocity due to the underlying emergent electromagnetic field. We validate the equation of motion by studying the depinning transition using both the particle and the continuum models. By using the particle description, we explain the recent experimental observations of the rotation of a skyrmion lattice in the presence of a temperature gradient. We also predict quantum and thermal creep motion of skyrmions in the pinning potential.

TI Infrared phonon modes in multiferroic single-crystal FeTe2O5Br SO PHYSICAL REVIEW B LA English DT Article AB Reflection and transmission as a function of temperature (7-300 K and 5-300 K respectively) have been measured on single crystals of the multiferroic compound FeTe2O5Br utilizing light spanning from the far infrared to the visible. The complex dielectric function and other optical properties were obtained via Kramers-Kronig analysis and by fits to a Drude-Lortentz model. Analysis of the anisotropic excitation spectra via Drude-Lorentz fitting and lattice dynamical calculations have led to the observation of 43 of the 53 modes predicted along the b axis of the monoclinic cell. The phonon response parallel to the a and c axes are also presented. Assignments to groups (clusters) of phonons have been made and trends within them are discussed in light of our calculated displacement patterns. C1 [Miller, K.

TI Three-dimensional Dirac fermions in quasicrystals as seen via optical conductivity SO PHYSICAL REVIEW B LA English DT Article ID ELECTRONIC-PROPERTIES; TRANSPORT-PROPERTIES; ALLOYS; BANDS AB The optical conductivity of quasicrystals is characterized by two features not seen in ordinary metallic systems. There is an absence of the Drude peak and the interband conductivity rises linearly from a very low value up to normal metallic levels over a wide range of frequencies. The absence of a Drude peak has been attributed to a pseudogap at the Fermi surface but a detailed explanation of the linear behavior has not been found. Here we show that the linear conductivity, which seems to be universal in all Al based icosahedral quasicrystal families, as well as their periodic approximants, follows from a simple model that assumes that the entire Fermi surface is gapped except at a finite set of Dirac points. There is no evidence of a semiconducting gap in any of the materials suggesting that the Dirac spectrum is massless, protected by topology leading to a Weyl semimetal. This model gives rise to a linear conductivity with only one parameter, the Fermi velocity. This picture suggests that decagonal quasicrystals should, like graphene, have a frequency independent conductivity, without a Drude peak. This is in accord with the experimental data as well.

CA STAR Collaboration TI System-size dependence of transverse momentum correlations at root s(NN)=62.4 and 200 GeV at the BNL Relativistic Heavy Ion Collider SO PHYSICAL REVIEW C LA English DT Article ID BY-EVENT FLUCTUATIONS; PLUS PB COLLISIONS; QUARK-GLUON PLASMA; AU-AU COLLISIONS; MEAN-P(T) FLUCTUATIONS; NUCLEAR COLLISIONS; SIGNATURES; DYNAMICS; MODEL; RATIO AB We present a study of the average transverse momentum (p(t)) fluctuations and p(t) correlations for charged particles produced in Cu + Cu collisions at midrapidity for root s(NN) = 62.4 and 200 GeV. These results are compared with those published for Au + Au collisions at the same energies, to explore the system size dependence. In addition to the collision energy and system size dependence, the p(t) correlation results have been studied as functions of the collision centralities, the ranges in p(t), the pseudorapidity eta, and the azimuthal angle phi. The square root of the measured p(t) correlations when scaled by mean p(t) is found to be independent of both colliding beam energy and system size studied. Transport-based model calculations are found to have a better quantitative agreement with the measurements compared to models which incorporate only jetlike correlations.

Of particular interest is the response of the nucleus to a time-dependent external field that impacts the low-energy multipole and beta-decay strength, as well as individual nuclear excitations. Purpose: We propose a method to compute low-lying collective modes in deformed nuclei within the finite-amplitude method (FAM) based on the quasiparticle random-phase approximation (QRPA). By using the analytic property of the response function, we find the QRPA amplitudes by computing the residua of the FAM amplitudes by means of a contour integration around the QRPA poles in a complex frequency plane. Methods: We use superfluid nuclear density functional theory with Skyrme energy density functionals, the FAM-QRPA approach, and the conventional matrix formulation of the QRPA. Results: We demonstrate that the complex-energy FAM-QRPA method reproduces low-lying collective states obtained within the conventional matrix formulation of the QRPA theory. Illustrative calculations are performed for the isoscalar monopole strength in deformed Mg-24 and for low-lying K = 0 quadrupole vibrational modes of deformed Yb and Er isotopes. Conclusions: The proposed FAM-QRPA approach, in addition to providing a quick estimate of various strength functions, allows one to efficiently calculate the individual QRPA amplitudes of the low-lying collective modes in spherical and deformed nuclei throughout the entire nuclear landscape, in particular shape-vibrational and pairing-vibrational modes and beta-decay rates. It can also be employed in microscopic approaches to large-amplitude nuclear collective motion based on the adiabatic self-consistent collective coordinate method.

CA ATLAS Collaboration TI Search for resonant diboson production in the WW/WZ -> lvjj decay channels with the ATLAS detector at root s=7 TeV SO PHYSICAL REVIEW D LA English DT Article ID FINAL-STATE; COLLISIONS; BOSONS AB A search for resonant diboson production using a data sample corresponding to 4.7 fb(-1) of integrated luminosity collected by the ATLAS experiment at the Large Hadron Collider in pp collisions at root s = 7 TeV is presented. The search for a narrow resonance in the WW or WZ mass distribution is conducted in a final state with an electron or a muon, missing transverse momentum, and at least two jets. No significant excess is observed and limits are set using three benchmark models: WW resonance masses below 940 and 710 GeV are excluded at 95% confidence level for spin-2 Randall-Sundrum and bulk Randall-Sundrum gravitons, respectively; WZ resonance masses below 950 GeV are excluded at 95% confidence level for a spin-1 extended gauge model W' boson.

CA CMS Collaboration TI Search for narrow resonances using the dijet mass spectrum in pp collisions at root s=8 TeV SO PHYSICAL REVIEW D LA English DT Article ID HADRON COLLIDERS; PHENOMENOLOGY; PHYSICS AB Results are presented of a search for the production of new particles decaying to pairs of partons (quarks, antiquarks, or gluons), in the dijet mass spectrum in proton-proton collisions at root s = 8 TeV. The data sample corresponds to an integrated luminosity of 4.0 fb(-1), collected with the CMS detector at the LHC in 2012. No significant evidence for narrow resonance production is observed. Upper limits are set at the 95% confidence level on the production cross section of hypothetical new particles decaying to quark-quark, quark-gluon, or gluon-gluon final states. These limits are then translated into lower limits on the masses of new resonances in specific scenarios of physics beyond the standard model. The limits reach up to 4.8 TeV, depending on the model, and extend previous exclusions from similar searches performed at lower collision energies. For the first time mass limits are set for the Randall-Sundrum graviton model in the dijet channel. C1 [Chatrchyan, S.; Khachatryan, V.; Sirunyan, A.

The merit of the reconstructions was judged using a new method of Fourier phase correlation with a final, refined image. The porous structure was found to have a much larger average size then previously believed. (C) 2013 Elsevier B.V. All rights reserved.

We discuss why the diffusion equation on the sphere provides a particularly attractive means of smoothing two-dimensional maps of global climate data. We establish that no structure is introduced into a map as an artifact of the smoothing procedure. This allows for the comparison of models and observations at multiple scales. As a test case for these methods, we compare the ability of high- and low-resolution versions of the Community Climate System Model (CCSM) to simulate the seasonal climatologies of surface air temperature (TAS), sea level pressure (PSL), and total precipitation rate (PR). For TAS, we find that the high-resolution model is better able to capture the boreal summer (JJA) climatological pattern at fine scales, although there is no such improvement in winter (DJF). We find the performances of the high- and low-resolution models to be similarly capable of capturing the summertime sea level pressure climatology at all scales. However, the high-resolution model PSL climatology is degraded for DJF, especially at larger scales. For both JJA and DJF precipitation climatologies, we find larger precipitation errors in the high-resolution model at the finest scales; however, performance at larger scales is improved.

However, we show that variability on time scales of 2-15 years in mean annual global land surface temperature anomalies T-avg are more closely correlated with variability in sea surface temperatures in the North Atlantic. In particular, the cross-correlation of annually averaged values of T-avg with annual values of the Atlantic Multidecadal Oscillation (AMO) index is much stronger than that of T-avg with ENSO. The pattern of fluctuations in T-avg from 1950 to 2010 reflects true climate variability and is not an artifact of station sampling. A world map of temperature correlations shows that the association with AMO is broadly distributed and unidirectional. The effect of El Nino on temperature is locally stronger, but can be of either sign, leading to less impact on the global average. We identify one strong narrow spectral peak in the AMO at period 9.10.4 years and p value of 1.7% (confidence level, 98.3%). Variations in the flow of the Atlantic meridional overturning circulation may be responsible for some of the 2-15 year variability observed in global land temperatures.

Sensitivity modeling experiments are performed for two distinct cloud regimes: maritime warm stratocumulus clouds (Sc) over southeast Pacific Ocean from the VOCALS project and continental deep convective clouds in the southeast of China. The results from Bulk-OR and Bulk-2M are compared against atmospheric observations and simulations produced by a spectral bin microphysical scheme (SBM). The prescribed aerosol approach (Bulk-OR) produces unreliable aerosol and cloud properties throughout the simulation period, when compared to the results from those using Bulk-2M and SBM, although all of the model simulations are initiated by the same initial aerosol concentration on the basis of the field observations. The impacts of the parameterizations of diffusional growth and autoconversion of cloud droplets and the selection of the embryonic raindrop radius on the performance of the bulk microphysical scheme are also evaluated by comparing the results from the modified Bulk-2M with those from SBM simulations. Sensitivity experiments using four different types of autoconversion schemes reveal that the autoconversion parameterization is crucial in determining the raindrop number, mass concentration, and drizzle formation for warm stratocumulus clouds. An embryonic raindrop size of 40 mu m is determined as a more realistic setting in the autoconversion parameterization. The saturation adjustment employed in calculating condensation/evaporation in the bulk scheme is identified as the main factor responsible for the large discrepancies in predicting cloud water in the Sc case, suggesting that an explicit calculation of diffusion growth with predicted supersaturation is necessary to improve the bulk microphysics scheme. Lastly, a larger rain evaporation rate below clouds is found in the bulk scheme in comparison to the SBM simulation, which may contribute to a lower surface precipitation in the bulk scheme.

TI Bounding the role of black carbon in the climate system: A scientific assessment SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Review DE black carbon; climate forcing; aerosol ID AEROSOL LIGHT-ABSORPTION; GENERAL-CIRCULATION MODEL; BIOMASS BURNING EMISSIONS; CIRRUS CLOUD FORMATION; GREENHOUSE-GAS EMISSIONS; AIRBORNE PARTICULATE MATTER; GLOBAL WARMING POTENTIALS; INDIAN-OCEAN EXPERIMENT; FOSSIL-FUEL COMBUSTION; CHEMICAL MASS-BALANCE AB Black carbon aerosol plays a unique and important role in Earth's climate system. Black carbon is a type of carbonaceous material with a unique combination of physical properties. This assessment provides an evaluation of black-carbon climate forcing that is comprehensive in its inclusion of all known and relevant processes and that is quantitative in providing best estimates and uncertainties of the main forcing terms: direct solar absorption; influence on liquid, mixed phase, and ice clouds; and deposition on snow and ice. These effects are calculated with climate models, but when possible, they are evaluated with both microphysical measurements and field observations. Predominant sources are combustion related, namely, fossil fuels for transportation, solid fuels for industrial and residential uses, and open burning of biomass. Total global emissions of black carbon using bottom-up inventory methods are 7500 Gg yr(-1) in the year 2000 with an uncertainty range of 2000 to 29000. However, global atmospheric absorption attributable to black carbon is too low in many models and should be increased by a factor of almost 3. After this scaling, the best estimate for the industrial-era (1750 to 2005) direct radiative forcing of atmospheric black carbon is +0.71 W m(-2) with 90% uncertainty bounds of (+0.08, +1.27) W m(-2). Total direct forcing by all black carbon sources, without subtracting the preindustrial background, is estimated as +0.88 (+0.17, +1.48) W m(-2). Direct radiative forcing alone does not capture important rapid adjustment mechanisms. A framework is described and used for quantifying climate forcings, including rapid adjustments. The best estimate of industrial-era climate forcing of black carbon through all forcing mechanisms, including clouds and cryosphere forcing, is +1.1 W m(-2) with 90% uncertainty bounds of +0.17 to +2.1 W m(-2). Thus, there is a very high probability that black carbon emissions, independent of co-emitted species, have a positive forcing and warm the climate. We estimate that black carbon, with a total climate forcing of +1.1 W m(-2), is the second most important human emission in terms of its climate forcing in the present-day atmosphere; only carbon dioxide is estimated to have a greater forcing. Sources that emit black carbon also emit other short-lived species that may either cool or warm climate. Climate forcings from co-emitted species are estimated and used in the framework described herein. When the principal effects of short-lived co-emissions, including cooling agents such as sulfur dioxide, are included in net forcing, energy-related sources (fossil fuel and biofuel) have an industrial-era climate forcing of +0.22 (-0.50 to +1.08) W m(-2) during the first year after emission. For a few of these sources, such as diesel engines and possibly residential biofuels, warming is strong enough that eliminating all short-lived emissions from these sources would reduce net climate forcing (i.e., produce cooling). When open burning emissions, which emit high levels of organic matter, are included in the total, the best estimate of net industrial-era climate forcing by all short-lived species from black-carbon-rich sources becomes slightly negative (-0.06 W m(-2) with 90% uncertainty bounds of -1.45 to +1.29 W m(-2)). The uncertainties in net climate forcing from black-carbon-rich sources are substantial, largely due to lack of knowledge about cloud interactions with both black carbon and co-emitted organic carbon. In prioritizing potential black-carbon mitigation actions, non-science factors, such as technical feasibility, costs, policy design, and implementation feasibility play important roles. The major sources of black carbon are presently in different stages with regard to the feasibility for near-term mitigation. This assessment, by evaluating the large number and complexity of the associated physical and radiative processes in black-carbon climate forcing, sets a baseline from which to improve future climate forcing estimates.

The GEOS-Chem chemical transport model is used to provide prior information for the Aerosol Optical Depth (AOD) retrieval and to relate total column AOD to PM2.5. We adjust the shape of the GEOS-Chem relative vertical extinction profiles by comparison with lidar retrievals from the CALIOP satellite instrument. Surface reflectance relationships used in the OE algorithm are indexed by land type. Error quantities needed for this OE algorithm are inferred by comparison with AOD observations taken by a worldwide network of sun photometers (AERONET) and extended globally based upon aerosol speciation and cross correlation for simulated values, and upon land type for observational values. Significant agreement in PM2.5 is found over North America for 2005 (slope=0.89; r=0.82; 1-sigma error=1 mu g/m(3)+27%), with improved coverage and correlation relative to previous work for the same region and time period, although certain subregions, such as the San Joaquin Valley of California are better represented by previous estimates. Independently derived error estimates of the OE PM2.5 values at in situ locations over North America (of (2.5 mu g/m(3)+31%) and Europe of (3.5 mu g/m(3)+30%) are corroborated by comparison with in situ observations, although globally (error estimates of (3.0 mu g/m(3)+35%), may be underestimated. Global population-weighted PM2.5 at 50% relative humidity is estimated as 27.8 mu g/m(3) at 0.1 degrees x0.1 degrees resolution.

TI Cloud effects on radiative heating rate profiles over Darwin using ARM and A-train radar/lidar observations SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article DE cloud forcing; radiative heating; A-train; ARM ID ICE WATER-CONTENT; GENERAL-CIRCULATION MODEL; DATA ASSIMILATION SYSTEM; CIRRUS CLOUDS; MEASUREMENT PROGRAM; ACCURATE PARAMETERIZATION; ALGORITHM DESCRIPTION; TROPICAL TROPOPAUSE; RADAR REFLECTIVITY; LOWER STRATOSPHERE AB Observations of clouds from the ground-based U.S. Department of Energy Atmospheric Radiation Measurement (ARM) program and satellite-based A-train are used to compute cloud radiative forcing profiles over the ARM Darwin, Australia site. Cloud properties are obtained from both radar (the ARM Millimeter Cloud Radar (MMCR) and the CloudSat satellite in the A-train) and lidar (the ARM Micropulse lidar (MPL) and the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite in the A-train) observations. Cloud microphysical properties are taken from combined radar and lidar retrievals for ice clouds and radar-only or lidar-only retrievals for liquid clouds. Large, statistically significant differences of up to 1.43K/d exist between the mean ARM and A-train net cloud radiative forcing profiles. The majority of the difference in cloud radiative forcing profiles is shown to be due to a large difference in the cloud fraction above 12km. Above this altitude, the A-train cloud fraction is significantly larger because many more clouds are detected by CALIPSO than by the ground-based MPL. It is shown that the MPL is unable to observe as many high clouds as CALIPSO due to being more frequently attenuated and a poorer sensitivity. We also isolate the difference in cloud radiative forcing due to sampling and retrieval differences which are of comparable importance but are of smaller impact than cloud fraction differences. This study demonstrates that A-train observations are better suited for the calculation of cloud radiative forcing profiles at Darwin. In addition, we find that it is necessary to supplement CloudSat with CALIPSO observations to obtain accurate cloud radiative forcing profiles.

The study was organized to address issues simultaneously relevant to atmospheric pollution and climate change, including (1) emission inventory assessment, (2) atmospheric transport and dispersion, (3) atmospheric chemical processing, and (4) cloud-aerosol interactions and aerosol radiative effects. Measurements from networks of ground sites, a research ship, tall towers, balloon-borne ozonesondes, multiple aircraft, and satellites provided in situ and remotely sensed data on trace pollutant and greenhouse gas concentrations, aerosol chemical composition and microphysical properties, cloud microphysics, and meteorological parameters. This overview report provides operational information for the variety of sites, platforms, and measurements, their joint deployment strategy, and summarizes findings that have resulted from the collaborative analyses of the CalNex field study. Climate-relevant findings from CalNex include that leakage from natural gas infrastructure may account for the excess of observed methane over emission estimates in Los Angeles. Air-quality relevant findings include the following: mobile fleet VOC significantly declines, and NOx emissions continue to have an impact on ozone in the Los Angeles basin; the relative contributions of diesel and gasoline emission to secondary organic aerosol are not fully understood; and nighttime NO3 chemistry contributes significantly to secondary organic aerosol mass in the San Joaquin Valley. Findings simultaneously relevant to climate and air quality include the following: marine vessel emissions changes due to fuel sulfur and speed controls result in a net warming effect but have substantial positive impacts on local air quality.

The first set of observations utilize archived European Space Agency C-band synthetic aperture radar data from 1992 through 1999 to image the long-term and large-scale subsidence at The Geysers. The peak range velocity of approximately 50mm/year agrees with previous estimates from leveling and global positioning system observations. Data from a second set of measurements, acquired by TerraSAR-X satellites, extend from May 2011 until April 2012 and overlap the C-band data spatially but not temporally. These X-band data, analyzed using a combined permanent and distributed scatterer algorithm, provide a higher density of scatterers (1122 per square kilometer) than do the C-band data (12 per square kilometer). The TerraSAR-X observations resolve 1 to 2cm of deformation due to water injection into a Northwest Geysers enhanced geothermal system well, initiated on October 2011. The temporal variation of the deformation is compatible with estimates from coupled numerical modeling. C1 [Vasco, D.

For new particle formation to take place, these clusters need to grow sufficiently fast to escape coagulation with preexisting particles. Previous studies indicated that condensation of low-volatility organic vapor may play an important role in the initial growth of the clusters. However, due to the relatively high vapor pressure and partial molar volume of even highly oxidized organic compounds, the strong Kelvin effect may prevent typical ambient organics from condensing on these small clusters. Here we show that the adsorption of organic molecules onto the surface of clusters, not considered previously, may significantly reduce the saturation ratio required for the condensation of organics to occur and therefore may provide a physicochemical explanation for the enhanced initial growth by condensation of organics despite the strong Kelvin effect.

TI NF-kappa B Regulates Radioresistance Mediated By beta 1-Integrin in Three-Dimensional Culture of Breast Cancer Cells SO CANCER RESEARCH LA English DT Article ID IN-VIVO; IONIZING-RADIATION; INDUCED APOPTOSIS; SUPEROXIDE-DISMUTASE; EPITHELIAL-CELLS; DRUG-RESISTANCE; CARCINOMA-CELLS; INHIBITION; ACTIVATION; THERAPY AB beta 1-integrin induction enhances breast cancer cell survival after exposure to ionizing radiation (IR), but the mechanisms of this effect remain unclear. Although NF-kappa B initiates prosurvival signaling pathways post-IR, the molecular function of NF-kappa B with other key elements in radioresistance, particularly with respect to extracellular matrix-induced signaling, is not known. We discovered a typical NF-kappa B-binding site in the beta 1-integrin promoter region, indicating a possible regulatory role for NF-kappa B. Using three-dimensional laminin-rich extracellular matrix (3D lrECM) culture, we show that NF-kappa B is required for beta 1-integrin transactivation in T4-2 breast cancer cells post-IR. Inhibition of NF-kappa B reduced clonogenic survival and induced apoptosis and cytostasis in formed tumor colonies. In addition, T4-2 tumors with inhibition of NF-kappa B activity exhibit decreased growth in athymic mice, which was further reduced by IR with downregulated beta 1-integrin expression. Direct interactions between beta 1-integrin and NF-kappa B p65 were induced in nonmalignant breast epithelial cells, but not in malignant cells, indicating context-specific regulation. As beta 1-integrin also activates NF-kappa B, our findings reveal a novel forward feedback pathway that could be targeted to enhance therapy. (c) 2013 AACR.

We show that via an appropriate operator splitting scheme, Kerr nonlinearity and the self-steepening and stimulated Raman scattering terms can be combined into a single sub-step consisting of an inhomogeneous quasilinear first-order hyperbolic system for the real-valued quantities intensity and phase. First- and second-order accurate shock-capturing upwind schemes have been developed specifically for this nonlinear sub-step, which enables the accurate and oscillation-free simulation of signals under the influence of Raman scattering and extreme self-steepening with the SSFM. Benchmark computations of ultra-fast Gaussian pulses in fibers with strong nonlinearity demonstrate the superior approximation properties of the proposed approach.

The composition (in wt.%) of the packs was 2NiAl-2NH(4)Cl-xHf-(96 - x)Al2O3 with different Hf levels (x = 2, 6, 12 and 16), and the corresponding microstructure of the coatings was gamma-Ni + gamma'-Ni3Al, NiAl + Al16Hf6Ni7, Al16Hf6Ni7 and Al1.65HfNi0.35, respectively. In the post heat-treatment process, with Hf and Al diffusing towards the superalloy substrate and Ni diffusing in the opposite direction, Al16Hf6Ni7 and Al1.65HfNi0.35 were transformed into Ni3Al + Al3HfNi12 and NiAl + Al3HfNi12, respectively. The isothermal oxidation tests at 1000 degrees C in air indicated that the coating formed in the packs containing 2 wt.% Hf had the lowest weight gain, while the weight gain of the coating formed in the packs having 6 wt.% Hf was the largest. The mechanisms of Hf-rich phase formation and their effects on oxidation resistance of the coatings were discussed. (C) 2013 Elsevier B.V. All rights reserved. C1 [Cao, G. H.; Yao, P.

The Euler equations of compressible hydrodynamics in the weak form are discretized using Non-Uniform Rational B-Splines (NURBS) in space. The discretization has all the advantages of a higher-order method, with the additional benefits of exact symmetry preservation and better per-degree-of-freedom accuracy. An explicit, second-order accurate time integration procedure, which conserves total energy, is developed and employed to advance the equations in time. The performance of the method is examined on a set of standard 2D and 3D benchmark examples, where good quality of the computational results is attained. (C) 2013 Elsevier Inc. All rights reserved.

TI A domain decomposition method for pseudo-spectral electromagnetic simulations of plasmas SO JOURNAL OF COMPUTATIONAL PHYSICS LA English DT Article DE Particle-In-Cell; Spectral; Electromagnetic; Fast fourier transform; FFT; Domain decomposition; Parallel ID CHARGE CONSERVATION; ACCELERATORS; INSTABILITY; SOLVERS AB Pseudo-spectral electromagnetic solvers (i.e. representing the fields in Fourier space) have extraordinary precision. In particular, Haber et al. presented in 1973 a pseudo-spectral solver that integrates analytically the solution over a finite time step, under the usual assumption that the source is constant over that time step. Yet, pseudo-spectral solvers have not been widely used, due in part to the difficulty for efficient parallelization owing to global communications associated with global FFTs on the entire computational domains. A method for the parallelization of electromagnetic pseudo-spectral solvers is proposed and tested on single electromagnetic pulses, and on Particle-In-Cell simulations of the wakefield formation in a laser plasma accelerator. The method takes advantage of the properties of the Discrete Fourier Transform, the linearity of Maxwell's equations and the finite speed of light for limiting the communications of data within guard regions between neighboring computational domains. Although this requires a small approximation, test results show that no significant error is made on the test cases that have been presented. The proposed method opens the way to solvers combining the favorable parallel scaling of standard finite-difference methods with the accuracy advantages of pseudo-spectral methods.

The equations are applicable for a domain composed of several materials with distinct refractive indexes. In such applications, the fundamental radiation variable, the intensity I, is discontinuous across material interfaces. The diffusion equations evolve a variable n, the integral of I over all directions divided by the square of the refractive index. Attention is focused on boundary and internal interface conditions for n. For numerical solutions using finite elements, it is shown that at material interfaces, the usual diffusion coefficient 1/3 kappa of the multifrequency equation, where kappa is the opacity, is modified by a tensor diffusion term consisting of integrals of the reflectivity. Numerical results are presented. For a single material simulation, the xi equations yield the same result as diffusion equations that evolve the spectral radiation energy density. A second simulation solves a test problem that models radiation transport in a domain comprised of materials with different refractive indexes. Results qualitatively agree with those previously published. (C) 2013 Elsevier Inc. All rights reserved. C1 Lawrence Livermore Natl Lab, Livermore, CA 94550 USA.

By using functional integral methods, we derive exact evolution equations for the probability density function (PDF) of the state variables of the advection-reaction system in the presence of random transport velocity and random reaction rates with rather arbitrary distributions. These PDF equations are solved analytically for transport with deterministic flow velocity and a linear reaction rate represented mathematically by a heterogeneous and strongly-correlated random field. Our analytical solution is then used to investigate the accuracy and robustness of the recently proposed large-eddy diffusivity (LED) closure approximation [1]. We find that the solution to the LED-based PDF equation, which is exact for uncorrelated reaction rates, is accurate even in the presence of strong correlations and it provides an upper bound of predictive uncertainty.

The mixed (ZnO:GaN) thin films deposited under Ar gas ambient failed to reduce the bandgap, whereas (ZnO:GaN) thin films grown under mixed O-2 and N-2 gas ambient showed bandgap reduction. The (ZnO:GaN) films deposited under mixed O-2 and N-2 gas exhibited enhanced crystallinity, with shifting the optical absorption into the visible light regions. The bandgap reduction in mixed (ZnO:GaN) thin films is realized by varying the RF power. As a result, mixed (ZnO:GaN) films grown under mixed O-2 and N-2 showed higher photocurrents than the mixed (ZnO:GaN) thin films deposited under Ar gas ambient. Our results indicate that reduced bandgap with enhanced PEC response can be attained using the appropriate gas ambient and by varying the RF power using mixed (ZnO:GaN) films. (C) 2013 Elsevier B.V.

A reduced order modeling approach based on response surface techniques is developed for SOFC stacks. This approach creates a numerical model that can quickly compute desired performance variables of interest based on the stack's input parameter state. The developed method first carefully samples the multidimensional design space based on the input parameter ranges, automatically evaluates an existing detailed stack model at each of the sampled points, and performs regression for selected performance variables of interest to determine the response surfaces. After error analysis to ensure that sufficient accuracy is established for the response surfaces, they are then implemented in a calculator module for use by the system-level software. The benefit of this modeling approach is that it is sufficiently fast for integration with system modeling software while still providing high fidelity information about the internal distributions of key variables in the fuel cell. This paper describes the sampling, regression, sensitivity, error, and principal component analysis to identify the most appropriate methods for simulating a planar SOFC stack. (C) 2013 Elsevier B.V.

Strong oxidation-reduction reactions to produce GNS by the traditional Hummers' method are avoided. The experiments show that the glucose and tin tetrachloride can intercalate into the thin graphite flake to exfoliate graphite and form SnO2-C/GNS nanocomposite simultaneously during the hydrothermal process. The approach is quite simple and green. Meanwhile, the prepared SnO2-C/GNS nanocomposite as an anode material of lithium-ion batteries exhibits higher lithium storage capacity and better cycling performance compared to SnO2 nanoparticle and SnO2-C microsphere. It still delivers the reversible capacity of 703 mA h g(-1) after 80 cycles at a current density of 100 mA g(-1) and maintains 443 mA h g(-1) after 100 cycles at a current density of 1000 mA g(-1). The improvement in the performance of SnO2-C/GNS nanocomposite can be attributed to the fully confinement of SnO2 nanoparticles between the GNS and the carbon layer, which can effectively prevent the detachment and agglomeration of SnO2 and preserve the integrity of the nanostructure during charge/discharge cycling.

Li-insertion properties are evaluated in half-cell configuration, test cell (Li/Li(Mn1/3Ni1/3Fe1/3)O-2-PANI) comprising 0.2 mol. PANI delivered the reversible capacity of similar to 127, similar to 114 and similar to 110 mAh g(-1) at ultra-high current rate of 5, 30 and 40 C, respectively with exceptional cycleability between 2 and 4.5 V vs. Li. Such an exceptional performance is mainly due to the conducting pathways promoted by PANI network and it is revealed by impedance measurements. This result certainly provides the possibility of using such layered type Fe based cathode materials in high power Li-ion batteries to drive zero emission vehicles such as hybrid electric vehicles or electric vehicles applications in near future.

Here, we give an introduction to an atomistic first principles perspective on CCS. First, CCS is discussed in terms of variational nuclear charges in the context of conceptual density functional and molecular grand-canonical ensemble theory. Thereafter, we revisit the notion of compound pairs, related to each other via "alchemical" interpolations involving fractional nuclear charges in the electronic Hamiltonian. We address Taylor expansions in CCS, property nonlinearity, improved predictions using reference compound pairs, and the ounce-of-gold prize challenge to linearize CCS. Finally, we turn to machine learning of analytical structure property relationships in CCS. These relationships correspond to inferred, rather than derived through variational principle, solutions of the electronic Schrodinger equation. (C) 2013 Wiley Periodicals, Inc.

Here we present the first application of total internal reflection-Raman (TIR-Raman) spectroscopy, a surface-sensitive spectroscopy, to probe sulfate ion behavior at the buried hematite/solution interface. Hematite is the most thermodynamically stable iron oxide polymorph and as such is widely found in nature. Our results demonstrate the feasibility of a TIR-Raman approach to study simple, inorganic anion adsorption at buried interfaces. Moreover, our data suggest that inner-sphere sulfate adsorption proceeds in a bidentate fashion at the hematite surface. These results help clarify long-standing questions as to whether sulfate forms inner-sphere adsorption complexes at hematite surfaces in a mono- or bidentate fashion based on attenuated total reflection-infrared (ATR-IR) observations. Our results are discussed with perspective to this debate and the applicability of TIR-Raman spectroscopy to address ambiguities of ion adsorption to mineral surfaces. (C) 2013 Elsevier Inc.

Previous work on block copolymer electrolytes composed of polystyrene-b-poly(ethylene oxide) (SEO) and lithium bis(trifluoromethanesulfone) imide (LiTFSI) salt was restricted to lamellar morphologies. This study addresses both cylindrical and lamellar morphologies. The conductivity of low molecular weight samples decreases after they are annealed. In contrast, the conductivity of high molecular weight samples is generally unaffected by annealing. These results are explained in the context of connectivity and composition of the conducting phase. (c) 2013 Wiley Periodicals, Inc. J. Polym. Sci. Part B: Polym.

The extent of self-trapping of positive (P+) and negative (P) polarons is observed to be highly sensitive to molecular conformation that, in turn, controls the distribution of atomic charges within the polymers. It is shown that, to reach good agreement with recent experimental data on lattice distortion for P+ and P excitations, the polarization of the medium plays a critical role. The introduction of weak-trans defects along the MEH-PPV chain breaks the observed symmetry for P+ and P excitations. The P states exhibit more spatial localization owing to lattice relaxation than their vacuum counterparts in contrast to P+. These observations suggest higher mobilities of holes than that of electrons in MEH-PPV, in agreement with the experimental observations. The predicted binding, reorganization, and solvation energies for PPV and MEH-PPV are analyzed for this difference in the response behavior of holes and electrons for trans and cis distortions. This study allows for a better understanding of charge-transport and photophysical properties in -conjugated organic materials by analyzing their underlying structureproperty correlations.

LiNi0.5Co0.2Mn0.3O2 without electrolyte first converts from a layered structure to disordered LiM2O4-type spinel and M3O4-type spinel phase as the temperature increases, then two different types of disordered spinel phases are co-existed up to 600 degrees C and no further decomposition to MO-type rock salt phase is presented at all. The electrolyte accelerates the thermal decomposition of the charged cathode materials. The presence of the electrolyte alters the paths of the structural changes and lowers the onset temperatures of the thermal decomposition reactions. In the case of LiNi0.5Co0.2Mn0.3O2 with electrolyte, more dramatic structural changes are observed compared with LiNi0.5Co0.2Mn0.3O2 without electrolyte and MO-type rock salt phase and metallic phase are presented at the end of the heating.

Hydrogel composites containing hydroxyapatite (HA) are promising materials for orthopedic applications. In this study, injectable poly(ethylene glycol) (PEG) hydrogel precursor solutions containing HA particles and model protein bovine serum albumin (BSA) were synthesized in situ by photopolymerization. In vitro BSA release properties from the hydrogel composites containing various amounts of HA were investigated and discussed. Fourier transform infrared spectroscopy and scanning electron microscopy were employed to investigate the interaction between HA and the hydrogel network and the morphology of the hydrogel composites. It is found that PEG hydrogel composites containing HA sustained the release of BSA for at least 5 days and the presence of HA slowed down BSA release. Photopolymerized hydrogel composites containing HA may find potential use as a drug delivery matrix for orthopedic tissue engineering. (c) 2012 Wiley Periodicals, Inc. J. Appl. Polym.

TI Communication: Two-dimensional gas-phase coherent anti-Stokes Raman spectroscopy (2D-CARS): Simultaneous planar imaging and multiplex spectroscopy in a single laser shot SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID ROTATIONAL CARS; SCATTERING; TEMPERATURE; THERMOMETRY; MICROSCOPY; FLAMES; GENERATION; PROBE; N-2 AB Coherent anti-Stokes Raman spectroscopy (CARS) has been widely used as a powerful tool for chemical sensing, molecular dynamics measurements, and rovibrational spectroscopy since its development over 30 years ago, finding use in fields of study as diverse as combustion diagnostics, cell biology, plasma physics, and the standoff detection of explosives. The capability for acquiring resolved CARS spectra in multiple spatial dimensions within a single laser shot has been a long-standing goal for the study of dynamical processes, but has proven elusive because of both phase-matching and detection considerations. Here, by combining new phase matching and detection schemes with the high efficiency of femtosecond excitation of Raman coherences, we introduce a technique for single-shot two-dimensional (2D) spatial measurements of gas phase CARS spectra. We demonstrate a spectrometer enabling both 2D plane imaging and spectroscopy simultaneously, and present the instantaneous measurement of 15 000 spatially correlated rotational CARS spectra in N-2 and air over a 2D field of 40 mm(2).

That is, the phase factors, or quantum amplitudes, are retained. At a region of strong coupling, a trajectory can branch into multiple wavepackets. Directly following a hop, the two wavepackets remain in a region of nonadiabatic coupling and continue exchanging population. After these wavepackets have sufficiently separated in phase space, they should begin to evolve independently from one another, the process known as decoherence. Decoherence is not accounted for in the standard surface hopping algorithm and leads to internal inconsistency. FSSH is designed to ensure that at any time, the fraction of classical trajectories evolving on each quantum state is equal to the average quantum probability for that state. However, in many systems this internal consistency requirement is violated. Treating decoherence is an inherent problem that can be addressed by implementing some form of decoherence correction to the standard FSSH algorithm. In this study, we have implemented two forms of the instantaneous decoherence procedure where coefficients are reinitialized following hops. We also test the energy-based decoherence correction (EDC) scheme proposed by Granucci et al. and a related version where the form of the decoherence time is taken from Truhlar's Coherent Switching with Decay of Mixing method. The sensitivity of the EDC results to changes in parameters is also evaluated. The application of these computationally inexpensive ad hoc methods is demonstrated in the simulation of nonradiative relaxation in two conjugated oligomer systems, specifically poly-phenylene vinylene and poly-phenylene ethynylene. We find that methods that have been used successfully for treating small systems do not necessarily translate to large polyatomic systems and their success depends on the particular system under study.

TI Predicting the shock compression response of heterogeneous powder mixtures SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID CERAMIC POWDERS; COMPACTION; EQUATION; MODEL; STATE; DENSIFICATION; BEHAVIOR AB A model framework for predicting the dynamic shock-compression response of heterogeneous powder mixtures using readily obtained measurements from quasi-static tests is presented. Low-strain-rate compression data are first analyzed to determine the region of the bulk response over which particle rearrangement does not contribute to compaction. This region is then fit to determine the densification modulus of the mixture, sigma(D), an newly defined parameter describing the resistance of the mixture to yielding. The measured densification modulus, reflective of the diverse yielding phenomena that occur at the meso-scale, is implemented into a rate-independent formulation of the P-alpha model, which is combined with an isobaric equation of state to predict the low and high stress dynamic compression response of heterogeneous powder mixtures. The framework is applied to two metal + metal-oxide (thermite) powder mixtures, and good agreement between the model and experiment is obtained for all mixtures at stresses near and above those required to reach full density. At lower stresses, rate-dependencies of the constituents, and specifically those of the matrix constituent, determine the ability of the model to predict the measured response in the incomplete compaction regime.

Here we describe how the association of long-chain fatty acids to a partially unfolded, extracellular protein can alter the presentation to target cells and cellular effects. HAMLET ( human alpha-lactalbumin made lethal to tumor cells) is a tumoricidal complex of partially unfolded alpha-lactalbumin and oleic acid (OA). As OA lacks independent tumoricidal activity at concentrations equimolar to HAMLET, the contribution of the lipid has been debated. We show by natural abundance C-13 NMR that the lipid in HAMLET is deprotonated and by chromatography that oleate rather than oleic acid is the relevant HAMLET constituent. Compared with HAMLET, oleate ( 175 mu M) showed weak effects on ion fluxes and gene expression. Unlike HAMLET, which causes metabolic paralysis, fatty acid metabolites were less strongly altered. The functional overlap increased with higher oleate concentrations ( 500 mu M). Cellular responses to OA were weak or absent, suggesting that deprotonation favors cellular interactions of fatty acids. Fatty acids may thus exert some of their essential effects on host cells when in the deprotonated state and when presented in the context of a partially unfolded protein.

The ions were created and excited at the electron-beam ion-trap facility at the Lawrence Livermore National Laboratory and measured with a high-resolution grazing-incidence spectrometer. The spectral lines were studied in the 27-41 angstrom range and were analyzed by a comparison with synthetic spectra based on a collisional-radiative model. We determined that the emission includes not only electric-dipole-allowed transitions, but also several electric-quadrupole and magnetic-dipole transitions. Line-position uncertainties as low as 25 ppm were achieved. Thus, our measurements provide much-needed benchmarks for calculations of the atomic structure of highly charged ions with a partially filled subshell, since these ions are difficult to calculate due to electron-correlation effects.

Time delays can provide a powerful cosmographic probe through the "time-delay distance'' involving the ratio of lens, source, and lens-source distances. However, light curves of lensed images have measurement gaps, noise, systematics such as microlensing from substructure along an image line of sight, and no a priori functional model, making robust time-delay estimation challenging. Using Gaussian process techniques, we demonstrate success in accurate blind reconstruction of time delays and reduction in uncertainties for real data.

TI Behavior of the coupling parameter under isochoric heating in a high-Z plasma SO PHYSICAL REVIEW E LA English DT Article ID ONE-COMPONENT PLASMA; DENSE IONIZED MATTER; MOLECULAR-DYNAMICS; STATISTICAL-MECHANICS AB The ion-ion coupling parameter Gamma is estimated for tungsten along the rho = 40 g/cm(3) isochore corresponding to twice the normal density with temperatures ranging from 10 eV to 5 keV. Using a variety of approaches from a spherical Thomas-Fermi ion to a full three-dimensional orbital-free method, we show that along an isochore the effective ionic coupling parameter is almost constant over a wide range of temperatures ( in our case Gamma similar or equal to 20) due to the competition between rising temperatures and increased ionization. This Gamma-plateau effect depends on the chosen density and is well delineated at normal density but almost disappears at five times the normal density. This effect could be used to obtain well-defined and predictable experimental conditions. C1 [Clerouin, Jean; Robert, Gregory; Arnault, Philippe] CEA, DAM, DIF, F-91297 Arpajon, France.

Modeling airflow dynamics in health and disease is a key goal for predictive multiscale models of respiration. Past efforts to model changes in lung shape during breathing have measured shape at multiple breath-holds. However, breath-holds do not capture hysteretic differences between inspiration and expiration resulting from the additional energy required for inspiration. Alternatively, imaging dynamically - without breath-holds - allows measurement of hysteretic differences. In this study, we acquire multiple micro-CT images per breath (4DCT) in live rats, and from these images we develop, for the first time, dynamic volume maps. These maps show changes in local volume across the entire lung throughout the breathing cycle and accurately predict the global pressure-volume (PV) hysteresis. Male Sprague-Dawley rats were given either a full- or partial-lung dose of elastase or saline as a control. After three weeks, 4DCT images of the mechanically ventilated rats under anesthesia were acquired dynamically over the breathing cycle (11 time points, <= 100 ms temporal resolution, 8 cmH(2)O peak pressure). Non-rigid image registration was applied to determine the deformation gradient - a numerical description of changes to lung shape - at each time point. The registration accuracy was evaluated by landmark identification. Of 67 landmarks, one was determined misregistered by all three observers, and 11 were determined misregistered by two observers. Volume change maps were calculated on a voxel-by-voxel basis at all time points using both the Jacobian of the deformation gradient and the inhaled air fraction. The calculated lung PV hysteresis agrees with pressure-volume curves measured by the ventilator. Volume maps in diseased rats show increased compliance and ventilation heterogeneity. Future predictive multiscale models of rodent respiration may leverage such volume maps as boundary conditions.

The photoinduced orbital imbalance induces a coherent motion of the V-V dimers affecting the electronic structure. After the closing of the gap, Boltzmann scattering equilibrates the electron densities. If the electron density exceeds a critical value, a phase transition occurs to the metallic state. The model explains several key features, such as a structural bottleneck, coherent structural motion combined with phase shifts in the oscillation, the absence of ultrafast metal-to-insulator transitions, and the need for a critical fluency.

Conventional methods for advanced polarization control impose demanding requirements on material properties and attain only limited performance. We demonstrated ultrathin, broadband, and highly efficient metamaterial-based terahertz polarization converters that are capable of rotating a linear polarization state into its orthogonal one. On the basis of these results, we created metamaterial structures capable of realizing near-perfect anomalous refraction. Our work opens new opportunities for creating high-performance photonic devices and enables emergent metamaterial functionalities for applications in the technologically difficult terahertz-frequency regime.

Hydrogen atoms adsorbed onto sp-bonded carbon atoms can form both sp(2)- and sp(3)-hybridized bonds and can exist in three different geometries: in-plane, out-of-plane, and oblique-plane; this is in sharp contrast to hydrogenated graphene, which has only one hydrogenation geometry. The band gaps of hydrogenated graphyne can vary by similar to 3 eV as the geometry changes. We also find that change in the hydrogen concentration allows a large band-gap tuning of similar to 5 eV. Unlike hydrogenated graphene, in which H atoms show a tendency to cluster, H atoms tend to be dispersed in graphyne, making band-gap tuning feasible. These exotic properties in hydrogenated graphyne indicate that the band gap of hydrogenated graphyne can be tailored for new device applications. Furthermore, the composite of fully hydrogenated graphyne is C1H1.75, which has a hydrogen-to-carbon ratio greater than that of graphane (C1H1). This large hydrogen capacity (similar to 13 wt % H) suggests that graphyne also can be used as a high-capacity hydrogen storage material.

TI Electrochemically Driven Covalent Functionalization of Graphene from Fluorinated Aryl Iodonium Salts SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID HYDROGENATED AMORPHOUS-CARBON; LIGHT-EMITTING-DIODES; TRANSPARENT ELECTRODES; SYNCHROTRON-RADIATION; CORE-LEVEL; PHOTOEMISSION; FILMS; SPECTROSCOPY; SURFACE; GRAPHITE AB Chemical functionalization is required to adapt graphene's properties to many applications. However, most covalent functionalization schemes are spontaneous or defect driven and are not suitable for applications requiring directed assembly of molecules on graphene substrates. In this study, we demonstrate the electrochemically driven covalent bonding of trifluoromethylphenylene (CF3Ph) onto epitaxial graphene. Submonolayer and full monolayer chemisorption was demonstrated by varying the duration of the electrochemical driving potential. A 10x increase in the CF3Ph density was obtained by varying the duration of the graphene electrochemical potential by 4x. A maximum closed-pack density of 1 X 10(14) molecules.cm(-2) was observed. Chemical, electronic, and defect states of CF3Ph graphene were studied by photoemission spectroscopy, spatially resolved Raman spectroscopy, and water contact angle measurement. Covalent attachment rehybridized some of the delocalized graphene sp(2) orbitals to localized sp(3) states. Increased water contact angles and work functions were observed for increasing CF3Ph functionalization densities, which is consistent with increasing concentration and orientation of fluorine on the graphene surfaces. Control over the relative spontaneity (reaction rate) of covalent graphene functionalization is an important first step to the practical realization of directed molecular assembly on graphene.

MOF-5 is perhaps the archetypal MOF; in particular, many isoreticular analogues of MOF-5 have been synthesized, comprising alternative dicarboxylic acid ligands. In this contribution we introduce a new set of hypothesized MOF-5 analogues, constructed from commercially available organic molecules. We describe our automated procedure for hypothetical MOF design, comprising selection of appropriate ligands, construction of 3D structure models, and structure relaxation methods. 116 MOF-5 analogues were designed and characterized in terms of geometric properties and simulated methane uptake at conditions relevant to vehicular storage applications. A strength of the presented approach is that all of the hypothesized MOFs are designed to be synthesizable utilizing ligands purchasable online.

TI Thermal Evolution of Cation Distribution/Crystallite Size and Their Correlation with the Magnetic State of Yb-Substituted Zinc Ferrite Nanoparticles SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID MICROSTRUCTURE; BEHAVIOR AB Evolution of the structural and magnetic properties of ZnFe1.95Yb0.05O4 nanoparticles, prepared via a high-energy ball milling route and exposed to further thermal annealing/heating, was assessed in detail and correlation of these properties explored. inversion, heating of the sample to similar to 500 degrees C is found to rapidly alter the cation distribution from mixed to normal, in agreement with the known cation preferences. Under the same conditions the crystallite size only slowly grows. By further thermal treatment appreciably. An interrelationship among the lattice parameter, octahedral site occupancy, and crystallite size has been established. The observations are (a) both the site occupancy of Fe3+ at octahedral 16d spinel sites (N-16d(Fe3+)) and the cubic lattice parameter rapidly increase with an initial increase of the crystallite size, (b) the lattice parameter increases with increasing occupancy, N-16d(Fe3+), and (c) there appears to be a critical nanoparticle diameter (approximately 15 nm) above which both the site occupancy and lattice parameter values are saturated. The magnetic behavior of the annealed samples appears to be correlated to the evolution of both the cation distribution and crystallite size, as follows. As-prepared samples and those annealed at lower temperatures show superparamagnetic behavior at room temperature, presumably as a consequence of the Fe3+ distribution and strong Fe3+(8a)-O-Fe3+(16d) superexchange interactions. Samples with a nanopartide diameter greater than 12 nm and with almost normal distributions exhibit the paramagnetic state. The coercive field is found to decrease with an increase of the crystallite size. Partial Yb3+/Fe3+ substitution is found to increase the inversion parameter and saturation magnetization. Detailed knowledge of the thermal evolution of structural/microstructural parameters allows control over the cation distribution and crystallite size and hence the magnetic properties of nanoferrites.

TI Recombination of Allyl Radicals in the High Temperature Fall-Off Regime SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID SELF-REACTION; SHOCK-TUBE; EQUILIBRIUM-CONSTANT; PYROLYSIS; KINETICS; DECOMPOSITION; DISSOCIATION; ISOMERIZATION; COMBINATION; RELAXATION AB The recombination of allyl radicals (C3H5), generated from the dissociation of 1,5-hexadiene or allyl iodide dilute in krypton, has been investigated in a diaphragmless shock tube using laser schlieren densitometry, LS, (900-1700 K, 10 +/- 1, 29 +/- 3, 57 +/- 3, and 120 +/- 4 Torr). The LS density gradient profiles were simulated and excellent agreement was found between simulations and experimental profiles. Rate coefficients for C3H5I -> C3H5 + I and C3H5 + C3H5 -> C6H10 were obtained and showed strong fall-off. Second order rate coefficients for allyl radical recombination were determined as k(1a,124Torr) = (2.6 +/- 0.8) x 10(55) T-12.995 exp(-8426/T), k(1a,57Torr) = (1.7 +/- 0.5) x 10(60) T-14.49 exp(-9344/T), and k(1a,30Torr) = (7.5 + 2.3) x 10(66) T-15.935 exp(-10192/T) cm(3) mol(-1)s(-1). The contribution of a disproportionation channel in allyl radical reactions was assessed, and the best agreement was obtained with no more than 5% disproportionation. Notably, because both the forward and back reactions of C(6)H(1)0 reversible arrow C3H5 + C3H5 were measured, utilizing two different precursors, the equilibrium constant of this reaction could be found, suggesting an entropy of formation of 1,5-hexadiene, 87.3 cal mol(-1) K-1, which is significantly smaller than that group additivity predicts, but larger than other reference literature values.

Simulation of the results using derived rate expressions from a complementary diaphragmless shock tube/laser schlieren densitometry study provided excellent agreement with precursor consumption and formation of all major stable intermediates. No significant pressure dependence was observed at the present conditions. It was found that under the conditions of these experiments, reactions of allyl radicals in the cooling wave had to be accounted for to accurately simulate the experimental results, and this unusual situation is discussed. In the allyl iodide experiments, higher amounts of allene, propene, and benzene were found at lower temperatures than expected. Possible mechanisms are discussed and suggest that iodine containing species are responsible for the low temperature formation of allene, propene, and benzene.

ThX4 molecules are all confirmed as tetrahedral, while all UX4 molecules are predicted to adopt D-2d symmetry using density functional theory. Multireference coupled cluster approaches confirm the D-2d symmetry for UF4. The bonding is mostly ionic, and predicted formation energies for the halogen species show good agreement with experiment. Our calculated hydration energy of UF4 (-54.0 kcal/mol) is in very good agreement with the experimental data (-54.8 kcal/mol). We predict CCSD(T) formation energies of Delta(f)G[U(OH)(4)(g)] = -286.3 kcal/mol and Delta(f)G[U(OH)(4)(aq)] = -318.7 kcal/mol.

TI Ionic Liquids Based on Polynitrile Anions: Hydrophobicity, Low Proton Affinity, and High Radiolytic Resistance Combined SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID INDUCED REDOX REACTIONS; PYRROLIDINIUM SALTS; CONSTITUENT IONS; IMIDAZOLIUM; RADIATION; TRICYANOMETHANIDE; SOLVENTS; FRAGMENTATION; EXTRACTION; STABILITY AB Ionic liquids (IL) are being considered as replacements for molecular diluents in spent nuclear fuel reprocessing. This development is hampered by the dearth of constituent anions that combine high hydrophobicity, low metal cation and proton affinity, and radiation resistance. We demonstrate that polynitrile anions have the potential to meet these challenges. Unlike the great majority of organic anions, such polynitrile anions are resistant to oxidative fragmentation during radiolysis, yielding stable N- and C-centered radicals. Moreover, their radical dianions (generated by reduction of the anions) generally undergo protonation in preference to elimination of the cyanide. This is in contrast to fluorinated anions (another large class of anions with low proton affinity), for which radiation-induced release of fluoride is a common occurrence. The "weak spot" of the polynitrile anions appears to be their excited-state dissociation, but at least one of these anions, 1,1,2,3,3-pentacyanopropenide, is shown to resist fragmentation in room temperature radiolysis. We suggest beginning the exploration of ionic liquids based on such polynitrile anions. C1 [Shkrob, Ilya A.; Marin, Timothy W.] Argonne Natl Lab, Chem Sci & Engn Div, Argonne, IL 60439 USA.

This is similar to the scattering of photons from an atomic ensemble in a one-dimensional waveguide. The scaling of two-photon nonlinearity at single-photon resonance shows a nonmonotonic behavior with an increasing number of few identical 2LAs. The two-photon nonlinearity decays monotonically with an increasing number of atoms for incident photons detuned from single-photon resonance. Single-photon transport in two 2LAs is similar to that in a single V-type three-level atom (3LA). However, two-photon transport in these two systems shows very different line shapes. When single-photon transmission is zero in these systems, two transmitted photons are bunched together in a V-type 3LA, while their correlation is zero in two 2LAs. The difference in the two-photon line shape persists for few 2LAs and 3LAs. Therefore, the two-photon scattering of a tightly focused weak light beam can be used as a probe to detect atomic level structures of different atoms with similar transition energies.

Our results are important for understanding ODMR line shapes and for optimization of devices based on NV- centers. We determine the origins of several side features to the unperturbed NV- magnetic resonance by studying their magnetic field and microwave power dependences. Side resonances separated by around 130 MHz are due to hyperfine coupling between NV- centers and nearest-neighbor C-13 nuclear spins. Side resonances separated by approximately {40, 260, 300} MHz are found to originate from simultaneous spin flipping of NV- centers and single substitutional nitrogen atoms. All results are in agreement with the presented theoretical calculations.

TI Dimensionality-controlled Mott transition and correlation effects in single-layer and bilayer perovskite iridates SO PHYSICAL REVIEW B LA English DT Article ID SR2IRO4 AB We studied Sr2IrO4 and Sr3Ir2O7 using angle-resolved photoemission spectroscopy, making direct experimental determinations of intra- and intercell coupling parameters as well as Mott correlations and gap sizes. The results are generally consistent with LDA + U + spin-orbit coupling calculations, though the calculations missed the momentum positions of the dominant electronic states and neglected the importance of intercell coupling on the size of the Mott gap. The calculations also ignore the correlation-induced spectral peak widths, which are critical for making a connection to activation energies determined from transport experiments. The data indicate a dimensionality-controlled Mott transition in these 5d transition-metal oxides. C1 [Wang, Q.; Cao, Y.; Waugh, J. A.; Park, S. R.; Dessau, D.

TI Neutron inelastic scattering in natural Cu as a background in neutrinoless double-beta decay experiments SO PHYSICAL REVIEW C LA English DT Article ID CROSS-SECTIONS; GAMMA RAYS; CU-63; DETECTOR; NUCLEI; SEARCH; COPPER; FE-56; MASS AB Background: Experiments designed to study rare processes, such as neutrinoless double-beta decay (0 nu beta beta), are crucial tests for physics beyond the standard model. These experiments rely on reducing the intrinsic radioactive background to unprecedented levels, while adequately shielding the detectors from external sources of radioactivity. Purpose: The purpose of this work is focused on understanding the background rates from neutron interactions in Cu shielding in regions around the Q values of many candidate 0 nu beta beta decay isotopes, as well as providing data for benchmarking Monte Carlo simulations of background events. Methods: Using the broad-spectrum neutron beam at Los Alamos Neutron Science Center, we have measured gamma rays emitted from inelastic neutron scattering on Cu-nat. Results: We extracted the level cross sections from the gamma-production cross section for 46 energy levels in Cu-nat. These level cross sections were compared with the available experimental data, as well as the ENDF/B-VII evaluation for discrete levels. Conclusions: For energy levels above 2 MeV we found significant discrepancies between the suggested level cross sections for both nuclei and our data. We found reasonable agreement between our measurement and the ENDF/B-VII evaluation for the total neutron inelastic cross section in Cu-63. Our measurement of the total neutron inelastic scattering cross section in Cu-65 was 30% lower than the ENDF/B-VII evaluations, which we attribute to unobserved transitions in Cu-65. Furthermore, we found that the implementation of the ENDF/B-VII evaluation in simulations did not properly model the decay properties of the nucleus to the degree necessary for estimating backgrounds in rear-event searches. Finally, we examined the potential implications of our measurements on 0 nu beta beta measurements and found that many of the commonly studied 0 nu beta beta isotopes had Q values below the cutoff for ENDF/B-VII evaluated discrete levels in either Cu nucleus.

We observed a substantial deviation in energy of the L0(-1) (->) L-1(0) transition from the characteristic square root magnetic-field dependence of two-dimensional graphene. This deviation arises from the formation of an upper-hybrid mode between the Landau-level transition and the plasmon resonance. In the quantum regime, the hybrid mode exhibits a distinct dispersion relation, markedly different from that expected for conventional two-dimensional systems and highly doped graphene.

TI Enhancing glass-forming ability via frustration of nano-clustering in alloys with a high solvent content SO SCIENTIFIC REPORTS LA English DT Article ID BULK METALLIC GLASSES; ULTRAFINE GRAIN-STRUCTURE; SOFT-MAGNETIC-ALLOYS; HIGH B-S; AMORPHOUS PHASE; CU; ADDITIONS; CRYSTALLIZATION; KINETICS AB The glass-forming ability (GFA) of alloys with a high-solvent content such as soft magnetic Fe-based and Al-based alloys is usually limited due to strong formation of the solvent-based solid solution phase. Herein, we report that the GFA of soft magnetic Fe-based alloys (with >70 at.% Fe to ensure large saturation magnetization) could be dramatically improved by doping with only 0.3 at.% Cu which has a positive enthalpy of mixing with Fe. It was found that an appropriate Cu addition could enhance the liquid phase stability and crystallization resistance by destabilizing the alpha-Fe nano-clusters due to the necessity to redistribute the Cu atoms. However, excessive Cu doping would stimulate nucleation of the alpha-Fe nano-clusters due to the repulsive nature between the Fe and Cu atoms, thus deteriorating the GFA. Our findings provide new insights into understanding of glass formation in general. C1 [Li, H. X.; Gao, J. E.; Wu, Y.; Jiao, Z. B.; Lu, Z.

This behavior has been proposed as a self-actuating mechanism of SMPs in water/physiological media. However, control over the SMP actuation rate, a critical factor for in vivo transcatheter device delivery applications, has not been previously reported. Here, a series of polyurethane SMPs with systematically varied hydrophobicity is described that permits control of the time for their complete shape recovery in water from under 2 min to more than 24 h. This control over the SMP actuation rate can potentially provide significant improvement in their delivery under conditions, which may expose them to high-moisture environments prior to actuation.

By changing both the density of the organic functional group and the width of the aGNRs-f, a band gap tuning exhibits a fine three-family behaviour through the side effect. Meanwhile, the carriers at the conduction band minimum and the valence band maximum are located in both CH2C6H5 and aGNR regions when the density of CH2C6H5 is big, while they distribute dominantly in aGNR conversely. The fine band gap modulation effects make aGNRs-f good candidates with high quantum efficiency and a significantly wider wavelength range from 750 to 93 924 nm for lasers, light-emitting diodes and photodetectors due to the direct band gap and small carrier effective masses.

CA D0 Collaboration TI Measurement of direct CP violation parameters in B-+/- -> J/psi K-+/- and B-+/- -> J/psi pi(+/-) decays with 10.4 fb(-1) of Tevatron data SO PHYSICAL REVIEW LETTERS LA English DT Article ID DETECTOR; MODEL AB We present a measurement of the direct CP-violating charge asymmetry in B-+/- mesons decaying to J/psi K-+/- and J/psi pi(+/-) where J/psi decays to mu(+)mu(-), using the full run II data set of 10.4 fb(-1) of proton-antiproton collisions collected using the D0 detector at the Fermilab Tevatron Collider. A difference in the yield of B- and B+ mesons in these decays is found by fitting to the difference between their reconstructed invariant mass distributions resulting in asymmetries of A(J/psi K) = [0.59 +/- 0.37]%, which is the most precise measurement to date, and A(J/psi pi) = [-4.2 +/- 4.5]%. Both measurements are consistent with standard model predictions. C1 [Maciel, A. K. A.; Santos, A. S.] Ctr Brasileiro Pesquisas Fis, LAFEX, Rio De Janeiro, Brazil.

Subtle, changes in the end group functionality significantly impact the molecular electronic and optical properties of the PPVOs, resulting in broadly tunable and efficient UV absorption and photoluminescence spectra. Of particular interest is the NO2-substituted PPVO which exhibits photoluminescence color ranging from the blue to the red, thus encompassing the entire visible spectrum. Our experimental study and electronic structure calculations suggest that the formation of aggregates and strong dipole dipole solute solvent interactions are responsible for the observed strong solvatochromism. Experimental and theoretical results for the NH2-, H-, and NO2-substituted PPVOs suggest that the stabilization of ground or excited state dipoles leads to the blue or red shift of the optical spectra. The electroluminescence (EL) spectra of H-, COOH-, and NO2-PPVO have maxima at 487, 518, and 587 nm, respectively, in the OLED device. This trend in the EL spectra is in excellent agreement with the end group-dependent PL spectra of the PPVO thin-films.

TI The non-pathogenic Escherichia coli strain W secretes SslE via the virulence-associated type II secretion system beta SO BMC MICROBIOLOGY LA English DT Article DE Type II secretion; Surface display; Escherichia coli; Colonization factor ID PROTEIN-SECRETION; GENOME SEQUENCE; PATHWAY; LOCUS; K-12 AB Background: Many pathogenic E. coli strains secrete virulence factors using type II secretory systems, homologs of which are widespread in Gram-negative bacteria. Recently, the enteropathogenic Escherichia coli strain E2348/69 was shown to secrete and surface-anchor SslE, a biofilm-promoting virulence factor, via a type II secretion system. Genes encoding SslE and its associated secretion system are conserved in some non-pathogenic E. coli, including the commonly-used W (Waksman) strain. Results: We report here that E. coli W uses its type II secretion system to export a cognate SslE protein. SslE secretion is temperature-and nutrient-dependent, being robust at 37 degrees C in rich medium but strongly repressed by lower temperatures or nutrient limitation. Fusing either of two glycosyl hydrolases to the C-terminus of SslE prevented it from being secreted or surface-exposed. We screened mutations that inactivated the type II secretion system for stress-related phenotypes and found that inactivation of the secretion system conferred a modest increase in tolerance to high concentrations of urea. Additionally, we note that the genes encoding this secretion system are present at a hypervariable locus and have been independently lost or gained in different lineages of E. coli. Conclusions: The non-pathogenic E. coli W strain shares the extracellular virulence factor SslE, and its associated secretory system, with pathogenic E. coli strains. The pattern of regulation of SslE secretion we observed suggests that SslE plays a role in colonization of mammalian hosts by non-pathogenic as well as pathogenic E. coli. Our work provides a non-pathogenic model system for the study of SslE secretion, and informs future research into the function of SslE during host colonization.

TI In Situ X-ray Absorption Spectroscopy Investigation of a Bifunctional Manganese Oxide Catalyst with High Activity for Electrochemical Water Oxidation and Oxygen Reduction SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID OCTAHEDRAL MOLECULAR-SIEVES; DIOXIDE ELECTRODE; STRUCTURAL-CHARACTERIZATION; PHOTOELECTRON-SPECTROSCOPY; SUPERCAPACITOR ELECTRODE; ALKALINE ELECTROLYTE; THIN-FILMS; BIRNESSITE; DIFFRACTION; ELECTROCATALYSTS AB In situ X-ray absorption spectroscopy (XAS) is a powerful technique that can be applied to electrochemical systems, with the ability to elucidate the chemical nature of electrocatalysts under reaction conditions. In this study, we perform in situ XAS measurements on a bifunctional manganese oxide (MnOx) catalyst with high electrochemical activity for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). Using X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS), we find that exposure to an ORR-relevant potential of 0.7 V vs RHE produces a disordered (Mn3O4)-O-II,III,III phase with negligible contributions from other phases. After the potential is increased to a highly anodic value of 1.8 V vs RHE, relevant to the OER, we observe an oxidation of approximately 80% of the catalytic thin film to form a mixed Mn-III,Mn-IV oxide, while the remaining 20% of the film consists of a less oxidized phase, likely corresponding to unchanged (Mn3O4)-O-II,III,III. XAS and electrochemical characterization of two thin film catalysts with different MnOx thicknesses reveals no significant influence of thickness on the measured oxidation states, at either ORR or OER potentials, but demonstrates that the OER activity scales with film thickness. This result suggests that the films have porous structure, which does not restrict electrocatalysis to the top geometric layer of the film. As the portion of the catalyst film that is most likely to be oxidized at the high potentials necessary for the OER is that which is closest to the electrolyte interface, we hypothesize that the Mn-III,Mn-IV oxide, rather than (Mn3O4)-O-II,III,III,is the phase pertinent to the observed OER activity.

The cationic cobalt(II) alkyl complex [(PNHPCy)Co(CH2SiMe3)]BAr4F (4) (PNHPCy = bis[(2-dicyclohexylphosphino)ethyl]amine) is an active precatalyst for the hydrogenation of olefins and ketones and the acceptorless dehydrogenation of alcohols. To elucidate the possible involvement of the N-H group on the pincer ligand in the catalysis via a metal-ligand cooperative interaction, the reactivities of 4 and [(PNMePCy)Co(CH2SiMe3)]BAr4F (7) were compared. Complex 7 was found to be an active precatalyst for the hydrogenation of olefins. In contrast, no catalytic activity was observed using 7 as a precatalyst for the hydrogenation of acetophenone under mild conditions. For the acceptorless dehydrogenation of 1-phenylethanol, complex 7 displayed similar activity to complex 4, affording acetophenone in high yield. When the acceptorless dehydrogenation of 1-phenylethanol with precatalyst 4 was monitored by NMR spectroscopy, the formation of the cobalt(III) acetylphenyl hydride complex [(PNHPCy)Co-III(kappa 2-O,C-C6H4C(O)CH3)(H)]BAr4F (13) was detected. Isolated complex 13 was found to be an effective catalyst for the acceptorless dehydrogenation of alcohols, implicating 13 as a catalyst resting state during the alcohol dehydrogenation reaction. Complex 13 catalyzed the hydrogenation of styrene but showed no catalytic activity for the room temperature hydrogenation of acetophenone. These results support the involvement of metal-ligand cooperativity in the room temperature hydrogenation of ketones but not the hydrogenation of olefins or the acceptorless dehydrogenation of alcohols. Mechanisms consistent with these observations are presented for the cobalt catalyzed hydrogenation of olefins and ketones and the acceptorless dehydrogenation of alcohols.

TI Nonadiabatic Dynamics of Positive Charge during Photocatalytic Water Splitting on GaN(10-10) Surface: Charge Localization Governs Splitting Efficiency SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID DOMAIN AB-INITIO; MOLECULAR-DYNAMICS; VISIBLE-LIGHT; HYDROGEN-PRODUCTION; TITANIUM-DIOXIDE; ELECTRONIC-TRANSITIONS; COMPUTATIONAL MODEL; PROTON-TRANSFER; OXIDE SURFACES; SOLID-SOLUTION AB Photochemical water splitting is a promising avenue to sustainable, clean energy and fuel production Gallium nitride (GaN) and its solid solutions are excellent photocatalytic materials; however, the efficiency of the process is low on pure GaN, and cocatalysts are required to increase the yields. We present the first tune domain theoretical study of the initial steps of photocatalytic water splitting on a GaN surface. Our state-of-the-art simulation technique, combining nonadiabatic molecular dynamics and time dependent density functional theory, allows us to characterize the mechanisms and time scales of the evolution of the photogenerated positive charge (hole) and the subsequent proton transfer at the GaN/water interface. The calculations show that the hole loses its excess energy within 100 fs and localizes primarily on the nitrogen atoms of the GaN surface, initiating a sequence of proton-transfer events from the surface N-H group to the nearby OH groups and bulk water molecules. Water splitting requires hole localization on oxygen rather than nitrogen, necessitating nonadiabatic transitions uphill in energy on pure GaN. Such transitions happen rarely, resulting in low yields of the photocatalytic water splitting observed experimentally. We conclude that efficient cocatalysts should favor localization of the photogenerated hole on oxygen containing species at the semiconductor/water interface.

Our theoretical tools are the one-dimensional formulation of Fermi liquid entanglement familiar from discussions of the logarithmic violation of the area law and quantum Monte Carlo calculations. The main result is a formula for the oscillating term for any region geometry and a spherical Fermi surface in any dimension. Specializing to two dimensions, we compare this term to numerical calculations of Renyi entropies using the correlation function method and find excellent agreement. We also compare with quantum Monte Carlo data on interacting Fermi liquids where we also find agreement up to moderate interaction strengths.

Here, using multimodal neuroimaging and behavioral dependent variables in 73 human cocaine-addicted individuals and 47 healthy controls, we hypothesized and found that cocaine-addicted carriers of a 9R-allele exhibited higher responses to drug cues, but only among individuals who had used cocaine within 72 h of the study as verified by positive cocaine urine screens (a state characterized by intense craving). Importantly, this responsiveness to drug cues was reliably preserved across multimodal imaging and behavioral probes: psychophysiological event-related potentials, self-report, simulated cocaine choice, and fMRI. Because drug cues contribute to relapse, our results identify the DAT1R 9R-allele as a vulnerability allele for relapse especially during early abstinence (e.g., detoxification).

TI Doping dependence of the spin excitations in the Fe-based superconductors Fe1+yTe1-xSex SO PHYSICAL REVIEW B LA English DT Article AB The Fe1+yTe1-xSex series of materials is one of the prototype families of Fe-based superconductors. To provide further insight into these materials, we present systematic inelastic neutron scattering measurements of the low-energy spin excitations for x = 0.27, 0.36, 0.40, and 0.49. These measurements show an evolution of incommensurate spin excitations towards the (1/2,1/2,0) wave vector with doping. Concentrations (x = 0.40 and 0.49) which exhibit the most robust superconducting properties have spin excitations closest to (1/2,1/2,0) and also exhibit a strong spin resonance in the spin excitation spectrum below T-c. The resonance signal appears to be closer to (1/2,1/2,0) than the underlying spin excitations. We discuss the possible relationship between superconductivity and spin excitations at the (1/2,1/2,0) wave vector and the role that interstitial Fe may play. C1 [Christianson, A. D.; Lumsden, M.

TI Evolution of magnetic interactions in a pressure-induced Jahn-Teller driven magnetic dimensionality switch SO PHYSICAL REVIEW B LA English DT Article AB We present the results of high-field magnetization and muon-spin relaxation measurements on the coordination polymer CuF2(H2O)(2)(pyrazine) in pressures up to 22.5 kbar. We observe a transition from a quasi-two-dimensional to a quasi-one-dimensional antiferromagnetic phase at 9.1 kbar, driven by a rotation of the Jahn-Teller axis. Long-range antiferromagnetic ordering is seen in both regimes, as well as a phase separation in the critical pressure region. The magnetic dimensionality switching as pressure is increased is accompanied by a halving of the primary magnetic exchange energy J and a fivefold decrease in the ordering temperature T-N. J decreases gradually with pressure in the two-dimensional phase, and then increases in the one-dimensional regime. We relate both effects to the changes in the crystal structure with applied pressure. C1 [Ghannadzadeh, S.; Moeller, J. S.; Goddard, P. A.; Blundell, S.

We find that giant bowing effects for the defect formation energy can exist in semiconductor alloys. The bowing effect originates from the concentrated distribution of defects at low energy sites caused by the defect wave-function localization and the size-mismatch-induced strain effect. Because the bowing effect can drastically reduce the defect formation energy-even in dilute semiconductor alloys-it can have wide applications, such as alloy-enhanced defect solubility in semiconductors.

TI Helicity dynamics in stratified turbulence in the absence of forcing SO PHYSICAL REVIEW E LA English DT Article ID DIRECT NUMERICAL SIMULATIONS; INTERNAL GRAVITY-WAVES; MAGNETOHYDRODYNAMIC TURBULENCE; LIMITING DYNAMICS; ENERGY-SPECTRA; FROUDE-NUMBER; FLOW; SCALE; ROTATION AB A numerical study of decaying stably stratified flows is performed. Relatively high stratification (Froude number approximate to 10(-2)-10(-1)) and moderate Reynolds (Re) numbers (Re approximate to 3(-6) x 10(3)) are considered and a particular emphasis is placed on the role of helicity (velocity-vorticity correlations), which is not an invariant of the nondissipative equations. The problem is tackled by integrating the Boussinesq equations in a periodic cubical domain using different initial conditions: a nonhelical Taylor-Green (TG) flow, a fully helical Beltrami [Arnold-Beltrami-Childress (ABC)] flow, and random flows with a tunable helicity. We show that for stratified ABC flows helicity undergoes a substantially slower decay than for unstratified ABC flows. This fact is likely associated to the combined effect of stratification and large-scale coherent structures. Indeed, when the latter are missing, as in random flows, helicity is rapidly destroyed by the onset of gravitational waves. A type of large-scale dissipative "cyclostrophic" balance can be invoked to explain this behavior. No production of helicity is observed, contrary to the case of rotating and stratified flows. When helicity survives in the system, it strongly affects the temporal energy decay and the energy distribution among Fourier modes. We discover in fact that the decay rate of energy for stratified helical flows is much slower than for stratified nonhelical flows and can be considered with a phenomenological model in a way similar to what is done for unstratified rotating flows. We also show that helicity, when strong, has a measurable effect on the Fourier spectra, in particular at scales larger than the buoyancy scale, for which it displays a rather flat scaling associated with vertical shear, as observed in the planetary boundary layer.

We now report structures under low Mg2+ (2.5 mM Mg2+/5 mM Ca2+) as well as under high Ca2+ (5 mM Mg2+/45 mM Ca2+). Under low Mg2+, four Ca2+ and three Mg2+ occupy the same positions as in high-Mg2+ structures. Conversely, under low Mg2+, reexamination of the structure of Gla domain of activated Protein C (APC) complexed with soluble endothelial Protein C receptor (sEPCR) has position 4 occupied by Ca2+ and positions 1 and 7 by Mg2+. Nonetheless, in direct binding experiments, Mg2+ replaced three Ca2+ sites in the unliganded Protein C or APC. Further, the hiah-Ca2+ condition was necessary to replace Mg4 in the FVIIa/soluble TF structure. In biological studies, Mg enhanced phospholipid binding to FVIIa and APC at physiological Ca2+. Additionally, Mg2+ potentiated phospholipid-dependent activations of FIX and FX by FVIIa/TF and inactivation of activated factor V by APC. Since APC and FVIIa bind to sEPCR involving similar interactions, we conclude that under the low-Mg2+ condition, sEPCR binding to APC-Gla (or FVIIa-Gla) replaces Mg4 by Ca4 with an attendant conformational change in the Gla domain omega-loop. Moreover, since phospholipid and sEPCR bind to FVIIa or APC via the w-loop, we predict that phospholipid binding also induces the functional Ca4 conformation in this loop. Cumulatively, the data illustrate that Mg2+ and Ca2+ act in concert to promote coagulation and anticoagulation. (C) 2013 Published by Elsevier Ltd.

Within the framework of ab initio thermodynamics the structure and excess free energies are calculated as functions of temperature (T) and oxygen partial pressure (P-O2), for three competing interface terminations. Comparisons between measurements and calculations establish that the interface is oxygen terminated, and a structural phase transition is predicted in the range of experimentally accessible T and P-O2 from the calculated interfacial free energies.

TI Vaccination with Recombinant Mycobacterium tuberculosis PknD Attenuates Bacterial Dissemination to the Brain in Guinea Pigs SO PLOS ONE LA English DT Article ID HUMAN-IMMUNODEFICIENCY-VIRUS; CENTRAL-NERVOUS-SYSTEM; BCG VACCINATION; IMMUNE-RESPONSE; CHILDHOOD TUBERCULOSIS; AEROSOL CHALLENGE; PROTEIN-KINASE; MURINE MODEL; MENINGITIS; PATHOGENESIS AB Background: We have previously identified Mycobacterium tuberculosis PknD to be an important virulence factor required for the pathogenesis of central nervous system (CNS) tuberculosis (TB). Specifically, PknD mediates bacillary invasion of the blood-brain barrier, which can be neutralized by specific antisera, suggesting its potential role as a therapeutic target against TB meningitis. Methodology/Principal Findings: We utilized an aerosol challenge guinea pig model of CNS TB and compared the protective efficacy of recombinant M. tuberculosis PknD subunit protein with that of M. bovis BCG against bacillary dissemination to the brain. BCG vaccination limited the pulmonary bacillary burden after aerosol challenge with virulent M. tuberculosis in guinea pigs and also reduced bacillary dissemination to the brain (P = 0.01). PknD vaccination also offered significant protection against bacterial dissemination to the brain, which was no different from BCG (P > 0.24), even though PknD vaccinated animals had almost 100-fold higher pulmonary bacterial burdens. Higher levels of PknD-specific IgG were noted in animals immunized with PknD, but not in BCG-vaccinated or control animals. Furthermore, pre-incubation of M. tuberculosis with sera from PknD-vaccinated animals, but not with sera from BCG-vaccinated or control animals, significantly reduced bacterial invasion in a human blood-brain barrier model (P < 0.01). Conclusion: Current recommendations for administering BCG at birth are based on protection gained against severe disease, such as TB meningitis, during infancy. We demonstrate that vaccination with recombinant M. tuberculosis PknD subunit offers a novel strategy to protect against TB meningitis, which is equivalent to BCG in a guinea pig model. Moreover, since BCG lacks the PknD sensor, BCG could also be boosted to develop a more effective vaccine against TB meningitis, a devastating disease that disproportionately affects young children.

TI Effect of Nonsolvent Exposure on Morphology of Mesoporous Semicrystalline Block Copolymer Films SO MACROMOLECULES LA English DT Article ID SCATTERING; TECHNOLOGY; SEPARATORS; BATTERY AB Polystyrene-block-polyethylene-block-polystyrene (SES) copolymers were blended with homopolymer polystyrene (PS), and films of the blend were solvent cast using a doctor blade. The nonporous SES and PS films were exposed to both tetrahydrofuran (THF) and methanol (MeOH) in an alternating fashion for 1 min intervals three times, without letting the films dry between solvent immersions. At this point, either the films were removed from MeOH and dried or the films were immersed in THF and then dried. THF is a nonsolvent for crystalline polyethylene (PE) but a good solvent for both amorphous PE and PS. Methanol is a nonsolvent for semicrystalline PE, amorphous PE, and PS. Films that were dried with MeOH as the final nonsolvent were highly porous and exhibited high conductivity when swollen in a liquid electrolyte. In contrast, films that were dried with THF as the final nonsolvent were nonporous and exhibited poor conductivity when swollen in a liquid electrolyte. We study the fundamental effect of nonsolvent exposure on film properties using electron microscopy, nitrogen physisorption, and X-ray scattering techniques.

Alignment is observed over a wide range of field strengths (0.2-7 T); however, the highest field strengths studied produce the highest degree of alignment Experiments examining alignment of a disordered sample, cooled into the ordered state in the presence of a magnetic field, show that alignment mostly occurs during nucleation and growth of the block copolymer nanostructure. The slower secondary processes of defect annihilation and grain rotation progress are necessary in producing extremely highly aligned samples. At the highest field strength, due to the increased order disorder transition temperature (TOOT), selective ordering is likely observed at temperatures near the order disorder transition leading to nucleation of aligned block copolymer grains, resulting in faster and a higher degree of alignment. Additionally, at these high field strengths the alignment process appears to have a more complex defect production and removal process than at low field strengths. At low field strengths isotropic nucleation occurs, and then preferential growth of aligned block copolymer grains is primarily responsible for alignment Finally, an optimum alignment temperature is observed where the thermodynamic driving force for alignment, thermal disordering processes, and the kinetic effects governing block copolymer growth and defect removal are balanced.

The morphology is probed as a function of blend ratio (21, 28, 44, 54, and 70 wt % P3HT) and annealing using imaging techniques and soft X-ray scattering. The surface structure is detected with optical microscopy and atomic force microscopy (AFM), the inner film morphology and the near-surface structure with grazing incidence resonant soft X-ray scattering (GI-RSoXS) using different X-ray energies. Characteristic lateral structures determined with GI-RSoXS are in agreement with AFM observations and complemented with optical microscopy. The topography and the inner film morphology have the same structural length scales. Grazing incidence wide-angle X-ray scattering (GIWAXS) results confirm the crystallinity of the P3HT domains, which is increasing with annealing, and shows no indication for crystallinity in MEH-CN-PPV. In addition, GIWAXS measurements reveal a blend ratio dependent orientation of P3HT crystals. Absorption and photoluminescence measurements complement the structural investigations.

Small-amplitude oscillatory shear flow experiments were used to systematically investigate the rheological behavior of these environmentally friendly, biorenewable, aqueous dispersions as a function of angular frequency, solid content, and temperature. In addition, the morphology of the dispersions was investigated at 60 degrees C for different time intervals using transmission electron microscopy (TEM). The solid content and temperature were found to significantly affect the rheological behavior of the PUDs. The composition dependency of the complex viscosity (eta*) was found to be well described by the Krieger-Dougherty equation. Thermally induced gelation was observed for PUDs with a solid content >= 27 wt %. Although the viscoelastic behavior of the PUDs was Well described by the time temperature superposition (TTS) principle in a temperature range lower than the gel point, TTS failed to represent the behavior of the PUDs at temperatures near the critical gel point. The real time gelation behavior was also studied for different solid contents of PUDs under isothermal conditions over a wide range of angular frequencies. Furthermore, both G' and G" showed a power law relationship with the angular frequency at the gel point, with critical power law exponents similar to those predicted theoretically by percolation theory. Aggregation and interconnection of the nano-PU particles caused the formation of fractal gels at a critical temperature, as confirmed by TEM.

TI Crystal structure of the FRP and identification of the active site for modulation of OCP-mediated photoprotection in cyanobacteria SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE nonphotochemical quenching; Synechocystis ID ORANGE CAROTENOID PROTEIN; SYNECHOCYSTIS PCC 6803; BINDING; MECHANISM; RECOVERY; STATE; MODEL AB Photosynthetic reaction centers are sensitive to high light conditions, which can cause damage because of the formation of reactive oxygen species. To prevent high-light induced damage, cyanobacteria have developed photoprotective mechanisms. One involves a photoactive carotenoid protein that decreases the transfer of excess energy to the reaction centers. This protein, the orange carotenoid protein (OCP), is present in most cyanobacterial strains; it is activated by high light conditions and able to dissipate excess energy at the site of the light-harvesting antennae, the phycobilisomes. Restoration of normal antenna capacity involves the fluorescence recovery protein (FRP). The FRP acts to dissociate the OCP from the phycobilisomes by accelerating the conversion of the active red OCP to the inactive orange form. We have determined the 3D crystal structure of the FRP at 2.5 angstrom resolution. Remarkably, the FRP is found in two very different conformational and oligomeric states in the same crystal. Based on amino acid conservation analysis, activity assays of FRP mutants, FRP: OCP docking simulations, and coimmunoprecipitation experiments, we conclude that the dimer is the active form. The second form, a tetramer, may be an inactive form of FRP. In addition, we have identified a surface patch of highly conserved residues and shown that those residues are essential to FRP activity.

TI Muon spin rotation studies of niobium for superconducting rf applications SO PHYSICAL REVIEW SPECIAL TOPICS-ACCELERATORS AND BEAMS LA English DT Article ID HYDROGEN AB In this work we investigate superconducting properties of niobium samples via application of the muon spin rotation/relaxation (mu SR) technique. We employ for the first time the mu SR technique to study samples that are cut out from large and small grain 1.5 GHz radio frequency (rf) single cell niobium cavities. The rf test of these cavities was accompanied by full temperature mapping to characterize the rf losses in each of the samples. Results of the mu SR measurements show that standard cavity surface treatments like mild baking and buffered chemical polishing performed on the studied samples affect their surface pinning strength. We find an interesting correlation between high field rf losses and field dependence of the sample magnetic volume fraction measured via mu SR. The mu SR line width observed in zero-field-mu SR measurements matches the behavior of Nb samples doped with minute amounts of Ta or N impurities. A lower and an upper bound for the upper critical field H-c2 of these cutouts is found. C1 [Grassellino, A.; Beard, C.; Kolb, P.; Laxdal, R.; Lockyer, N.

It is based on using sum signals from beam position monitors sensitive to the longitudinal charge distribution in the bunch. The applicability of the method is demonstrated on the superconducting section of the Oak Ridge Spallation Neutron Source linear accelerator. The results are compared to a direct measurement of the bunch longitudinal profiles using an interceptive bunch shape monitor in the linac warm section of the same accelerator. Limitations of the method are discussed. The method is fast and simple, and can be used to obtain the initial parameters for the longitudinal matching in linear accelerators where interceptive diagnostics are not desirable.

We reveal the relationship between aqueous conditions and the amount of DNA conjugated on QDs, colloidal stability, and yield of the final QD-DNA conjugates. By carefully adjusting the environmental variables we have successfully achieved up to 20 DNA strands conjugated per QD, and demonstrated how this number can be tuned. The fabricated QD-DNA,conjugates are dispersed and optically stable in salted solutions for over a month. We have also evaluated the involved interparticle interactions to explain the solution behavior of QD-DNA conjugates. Our, results provide a basic understanding of the physiochemical processes governing a nanoparticle-biomolecule conjugation and the structural stability of the formed conjugates. Such fabricated QD-DNA conjugates, might be of great benefit for programmable assemblies of optically active nanomaterials and for emerging biosensing methods based on nanomaterials.

We have previously reported the structure of the periodic part of 1 by coupling synchrotron powder diffraction and solid-state nuclear magnetic resonance (NMR) crystallographies. With a similar strategy, that is, input of large parts of the building blocksdetermined by analysis of the Al-27-P-31 correlation pattern of the two-dimensional (2D) NMR spectrum in the structure search process, we first determine the periodic structure of 2, using the powder synchrotron diffraction data as cost function. Both 1 and 2 are layered materials, in which the inorganic layers contain five P and seven Alinequivalent atoms, with aluminum atoms that are found in three different coordination states, AlO4, AlO5, and AlO6, and the interlayer space contains the amines and water molecules. In 1, the inorganic layers are stacked on each other with a 42 element of symmetry along the c-axis, while they are stacked with a 180 degrees rotation angle in 2. By analysis of a set of high-resolution 1D and 2D NMR spectra (P-31, Al-27, H-1, N-15, C-13, Al-27-P-31, H-1-P-31, and H-1-N-14) the structure analysis of 1 and 2 is extended beyond the strict periodicity, to which diffraction is restricted, and provides localization of the hydroxyl groups and water molecules in the frameworks and an attempt to correlate the presence of these latter species to the structural features of the two samples is presented. Finally, the dehydration/rehydration processes occurring in these solids are analyzed. The methodology of the structure determination for these dehydrated forms uses the same principles, combining X-ray powder diffraction and solid-state NMR data.

Here, an approach is explored that uses crystalline Co3O4 as an oxygen evolving catalyst and a nanometer-thin dense phase silica layer as the separation barrier. For controlled charge transport across the barrier, hole conducting molecular wires are embedded in the silica. Spherical Co3O4(4 nm)-SiO2(2 nm) core-shell nanoparticles with p-oligo(phenylenevinylene) wire molecules (three aryl units, PV3) cast into the silica were developed to establish proof of concept for charge transport across the embedded wire molecules. FT-Raman, FT-infrared, and UV-Visible spectroscopy confirmed the integrity of the organic wires upon casting in silica. Transient optical absorption spectroscopy of a visible light sensitizer (ester derivatized [Ru(bpy)(3)](2+) complex) indicates efficient charge injection into Co3O4-SiO2 particles with embedded wire molecules in aqueous solution. An upper limit of a few microseconds is inferred for the residence time of the hole on the embedded PV3 molecule before transfer to Co3O4 takes place. The result was corroborated by light on/off experiments using rapid scan FT-IR monitoring. These observations indicate that hole conducting organic wire molecules cast into a dense phase, nanometer thin silica layer offer fast, controlled charge transfer through a product-s'epurating oxide barrier.

TI Defects in Hydrothermally Synthesized LiFePO4 and LiFe1-xMnxPO4 Cathode Materials SO CHEMISTRY OF MATERIALS LA English DT Article DE LiFePO4; defects; powder diffraction; total scattering ID LITHIUM IRON PHOSPHATE; X-RAY-DIFFRACTION; SUPERCRITICAL WATER; ROOM-TEMPERATURE; PREPARED LIFEPO4; SPECTROSCOPY; REACTIVITY; DIFFUSION; LIXFEPO4; OLIVINES AB The crystal structure and defect chemistry of hydrothermally synthesized LiFe1-xMnxPO4 (x = 0, 0.25, and 0.50) particles have been characterized by simultaneous neutron and X-ray Rietveld refinement as well as X-ray and neutron pair distribution function (PDF) analysis, crystallinity determination, Mossbauer spectroscopy, ion coupled plasma (ICP) studies, and scanning electron microscopy (SEM). The very detailed structural refinements show that fast hydrothermal synthesis causes partial Fe-occupancy and vacancies on the Li (M1) site, while the Fe (M2) site is always fully occupied by iron. Thus, the defect is not merely a Li/Fe antisite defect, and excessive amounts of Fe are the origin of the disorder in the structure. Neutron and X-ray total scattering with PDF analysis show that after fast hydrothermal synthesis, the crystalline, defective LixFeyPO4 coexists with amorphous Li/Fe-PO4 structures having just short-range order. Iron excess is only seen in the crystalline part of the particles, and as the crystallinity of the samples increases with longer synthesis time, the crystalline Fe/Li ratio approaches 1. The present data thus suggest that when crystalline particles initially form, Fe is included faster in the structure from the amorphous precursor than Li, causing the defects in the structure. Only when all Li have been incorporated into the crystal structure and 100% crystallinity is achieved, fully ordered, defect free samples can be obtained. The Fe occupancy on the M1 site is therefore directly linked to the crystallinity of the sample. In LiFe1-xMnxPO4 samples, the transition metal defect on the M1 site is only Fe and not Mn. Furthermore, the presence of Mn locks in the defects, and thus the Fe disorder is not suppressed with extended synthesis time. C1 [Jensen, Kirsten M.

The rechargeable capacity of the Li-ion battery is linked largely to the structural stability of the cathode materials during the charge-discharge cycles. However, the structure and cation distribution in Pristine Li1.2Ni0.2Mn0.6O2 have not yet been fully characterized. Using a combination of aberration-corrected scanning transmission electron microscopy, X-ray energy-dispersive spectroscopy (XEDS), electron energy loss spectroscopy (EELS), and complementary multislice image simulation, we have probed the crystal structure, cation/anion distribution, and electronic structure of the Li1.2Ni0.2Mn0.6O2 nanoparticle. The electronic structure and valence state of transition-metal ions show significant variations, which have been identified to be attributed to the oxygen deficiency near certain particle surfaces. Characterization of the nanoscale phase separation and cation ordering in the pristine material are critical for understanding the capacity and voltage fading of this material for battery application.

TI Disorder-controlled superconductivity at YBa2Cu3O7/SrTiO3 interfaces SO PHYSICAL REVIEW B LA English DT Article ID INSULATOR TRANSITION; OXIDE INTERFACES; MULTILAYERS; SUPERLATTICES; DEFECTS; STRAIN; SRTIO3; GROWTH; FILMS AB We examine the effect of interface disorder in suppressing superconductivity in coherently grown ultrathin YBa2Cu3O7 (YBCO) layers on SrTiO3 (STO) in YBCO/STO superlattices. The termination plane of the STO is TiO2 and the CuO chains are missing at the interface. Disorder (steps) at the STO interface cause alterations of the stacking sequence of the intracell YBCO atomic layers. Stacking faults give rise to antiphase boundaries which break the continuity of the CuO2 planes and depress superconductivity. We show that superconductivity is directly controlled by interface disorder outlining the importance of pair breaking and localization by disorder in ultrathin layers.

Kais, Sabre TI Quantum coherence and entanglement in the avian compass SO PHYSICAL REVIEW E LA English DT Article ID CHEMICAL COMPASS; MAGNETORECEPTION; BIRDS; CRYPTOCHROME; MODEL AB The radical-pair mechanism is one of two distinct mechanisms used to explain the navigation of birds in geomagnetic fields, however little research has been done to explore the role of quantum entanglement in this mechanism. In this paper we study the lifetime of radical-pair entanglement corresponding to the magnitude and direction of magnetic fields to show that the entanglement lasts long enough in birds to be used for navigation. We also find that the birds appear to not be able to orient themselves directly based on radical-pair entanglement due to a lack of orientation sensitivity of the entanglement in the geomagnetic field. To explore the entanglement mechanism further, we propose a model in which the hyperfine interactions are replaced by local magnetic fields of similar strength. The entanglement of the radical pair in this model lasts longer and displays an angular sensitivity in weak magnetic fields, both of which are not present in previous models.

TI Reduction of Edge-Localized Mode Intensity Using High-Repetition-Rate Pellet Injection in Tokamak H-Mode Plasmas SO PHYSICAL REVIEW LETTERS LA English DT Article ID DIII-D TOKAMAK; CONFINEMENT; TRANSPORT; DIVERTOR; SOL AB High repetition rate injection of deuterium pellets from the low-field side (LFS) of the DIII-D tokamak is shown to trigger high-frequency edge-localized modes (ELMs) at up to 12X the low natural ELM frequency in H-mode deuterium plasmas designed to match the ITER baseline configuration in shape, normalized beta, and input power just above the H-mode threshold. The pellet size, velocity, and injection location were chosen to limit penetration to the outer 10% of the plasma. The resulting perturbations to the plasma density and energy confinement time are thus minimal (< 10%). The triggered ELMs occur at much lower normalized pedestal pressure than the natural ELMs, suggesting that the pellet injection excites a localized high-n instability. Triggered ELMs produce up to 12X lower energy and particle fluxes to the divertor, and result in a strong decrease in plasma core impurity density. These results show for the first time that shallow, LFS pellet injection can dramatically accelerate the ELM cycle and reduce ELM energy fluxes on plasma facing components, and is a viable technique for real-time control of ELMs in ITER.

TI Temperature dependence of light absorption by water SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Water; Optical absorption; Temperature coefficient ID PURE WATER; SPECTRUM; HOD AB A model is described that relates the temperature coefficient of the optical absorption spectrum of pure water to the frequency derivative of that spectrum and two parameters that quantify the dependence of a peak's amplitude and its position on temperature. When applied to experimental temperature coefficients, it provides a better understanding of the process than the analysis currently in use. (C) 2013 Elsevier B.V. All rights reserved.

CA ATLAS Collaboration TI Search for a heavy narrow resonance decaying to e mu, e tau, or mu tau with the ATLAS detector in root s=7 TeV pp collisions at the LHC SO PHYSICS LETTERS B LA English DT Article ID NUMBER-NONCONSERVATION; GAUGE THEORIES; LEPTONS AB This Letter presents the results of a search for a heavy particle decaying into an e(+/-)mu(+/-), e(+/-)tau(+/-), or mu(+/-)tau(+/-) final state in pp collisions at root s = 7 TeV. The data were recorded with the ATLAS detector at the LHC during 2011 and correspond to an integrated luminosity of 4.6 fb(-1). No significant excess above the Standard Model expectation is observed, and exclusions at 95% confidence level are placed on the cross section times branching ratio for the production of an R-parity-violating supersymmetric tau sneutrino. For a sneutrino mass of 500 (2000) GeV, the observed limits on the production cross section times branching ratio are 3.2 (1.4) fb, 42 (17) fb, and 40 (18) fb for the e mu, e tau, and mu tau modes, respectively. These results considerably extend constraints from Tevatron experiments. (c) 2013 CERN. Published by Elsevier B.V. All rights reserved.

TI High-spin transition quadrupole moments in neutron-rich Mo and Ru nuclei: Testing gamma softness? SO PHYSICS LETTERS B LA English DT Article DE Rotational bands; Transition quadrupole moments; Triaxial nuclear shape; Cranked relativistic Hartree-Bogoliubov theory ID GROUND-STATE; GAMMASPHERE; EVOLUTION; ISOTOPES; SHAPES; BANDS AB The transition quadrupole moments, Q(t), of rotational bands in the neutron-rich, even-mass Mo102-108 and Ru108-112 nuclei were measured in the 8-16 (h) over bar spin range with the Doppler-shift attenuation method. The nuclei were populated as fission fragments from Cf-252 fission. The detector setup consisted of the Gammasphere spectrometer and the HERCULES fast-plastic array. At moderate spin, the Q(t) moments are found to be reduced with respect to the values near the ground states. Attempts to describe the observations in mean-field-based models, specifically cranked relativistic Hartree-Bogoliubov theory, illustrate the challenge theory faces and the difficulty to infer information on gamma softness and triaxiality from the data.

TI First measurement of theta(13) from delayed neutron capture on hydrogen in the Double Chooz experiment SO PHYSICS LETTERS B LA English DT Article AB The Double Chooz experiment has determined the value of the neutrino oscillation parameter theta(13) from an analysis of inverse beta decay interactions with neutron capture on hydrogen. This analysis uses a three times larger fiducial volume than the standard Double Chooz assessment, which is restricted to a region doped with gadolinium (Gd), yielding an exposure of 113.1 GW-ton-years. The data sample used in this analysis is distinct from that of the Gd analysis, and the systematic uncertainties are also largely independent, with some exceptions, such as the reactor neutrino flux prediction. A combined rate- and energy-dependent fit finds sin(2) 2 theta(13) = 0.097 +/- 0.034 (stat.) +/- 0.034 (syst.), excluding the no-oscillation hypothesis at 2.0 sigma. This result is consistent with previous measurements of sin(2) 2 theta(13). (c) 2013 Elsevier B.V. All rights reserved.

TI TOWARD A COMPLETE ACCOUNTING OF ENERGY AND MOMENTUM FROM STELLAR FEEDBACK IN GALAXY FORMATION SIMULATIONS SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: evolution; galaxies: ISM; ISM: structure; methods: numerical; stars: formation ID GIANT MOLECULAR CLOUDS; STAR-FORMING GALAXIES; COLD DARK-MATTER; KENNICUTT-SCHMIDT RELATION; ADAPTIVE MESH REFINEMENT; INITIAL MASS FUNCTION; INTERSTELLAR-MEDIUM; RADIATION-PRESSURE; COSMOLOGICAL SIMULATIONS; VELOCITY DISPERSION AB We investigate the momentum and energy budget of stellar feedback during different stages of stellar evolution, and study its impact on the interstellar medium (ISM) using simulations of local star-forming regions and galactic disks at the resolution affordable in modern cosmological zoom-in simulations. In particular, we present a novel subgrid model for the momentum injection due to radiation pressure and stellar winds from massive stars during early, pre-supernova (pre-SN) evolutionary stages of young star clusters. Early injection of momentum acts to clear out dense gas in star-forming regions, hence limiting star formation. The reduced gas density mitigates radiative losses of thermal feedback energy from subsequent SN explosions. The detailed impact of stellar feedback depends sensitively on the implementation and choice of parameters. Somewhat encouragingly, we find that implementations in which feedback is efficient lead to approximate self-regulation of the global star formation efficiency. We compare simulation results using our feedback implementation to other phenomenological feedback methods, where thermal feedback energy is allowed to dissipate over timescales longer than the formal gas cooling time. We find that simulations with maximal momentum injection suppress star formation to a similar degree as is found in simulations adopting adiabatic thermal feedback. However, different feedback schemes are found to produce significant differences in the density and thermodynamic structure of the ISM, and are hence expected to have a qualitatively different impact on galaxy evolution.

TI DETECTION OF THE COSMIC gamma-RAY HORIZON FROM MULTIWAVELENGTH OBSERVATIONS OF BLAZARS SO ASTROPHYSICAL JOURNAL LA English DT Article DE BL Lacertae objects: general; cosmology: observations; diffuse radiation; galaxies: evolution; galaxies: formation ID EXTRAGALACTIC BACKGROUND LIGHT; LARGE-AREA TELESCOPE; BL LACERTAE OBJECTS; INTERGALACTIC MAGNETIC-FIELD; SPECTRAL ENERGY-DISTRIBUTION; SED-TYPE FRACTIONS; TEV BLAZARS; NEXT-GENERATION; 3C 66A; COSMOLOGICAL PARAMETERS AB The first statistically significant detection of the cosmic gamma-ray horizon (CGRH) that is independent of any extragalactic background light (EBL) model is presented. The CGRH is a fundamental quantity in cosmology. It gives an estimate of the opacity of the universe to very high energy (VHE) gamma-ray photons due to photon-photon pair production with the EBL. The only estimations of the CGRH to date are predictions from EBL models and lower limits from gamma-ray observations of cosmological blazars and gamma-ray bursts. Here, we present homogeneous synchrotron/synchrotron self-Compton (SSC) models of the spectral energy distributions of 15 blazars based on (almost) simultaneous observations from radio up to the highest energy gamma-rays taken with the Fermi satellite. These synchrotron/SSC models predict the unattenuated VHE fluxes, which are compared with the observations by imaging atmospheric Cherenkov telescopes. This comparison provides an estimate of the optical depth of the EBL, which allows us a derivation of the CGRH through a maximum likelihood analysis that is EBL-model independent. We find that the observed CGRH is compatible with the current knowledge of the EBL. C1 [Dominguez, A.; Siana, B.] Univ Calif Riverside, Dept Phys & Astron, Riverside, CA 92521 USA. [Finke, J.

TI Low-energy electron reflectivity of graphene on copper and other substrates SO PHYSICAL REVIEW B LA English DT Article ID SURFACE-STATES; WORK-FUNCTIONS; AG FILMS; GRAPHITE; PHOTOEMISSION; LEED; TRANSMISSION; 6H-SIC(0001); W(110); BANDS AB The reflectivity of low-energy electrons from graphene on copper substrates is studied both experimentally and theoretically. Well-known oscillations in the reflectivity of electrons with energies 0-8 eV above the vacuum level are observed in the experiment. These oscillations are reproduced in theory, based on a first-principles density functional description of interlayer states forming for various thicknesses of multilayer graphene. It is demonstrated that n layers of graphene produce a regular series of n - 1 minima in the reflectance spectra, together with a possible additional minimum associated with an interlayer state forming between the graphene and the substrate. Both (111) and (001) orientations of the copper substrates are studied. Similarities in their reflectivity spectra arise from the interlayer states, whereas differences are found because of the different Cu band structures along those orientations. Results for graphene on other substrates, including Pt(111) and Ir(111), are also discussed. C1 [Srivastava, N.; Gao, Qin; Widom, M.; Feenstra, R.

Significant anisotropy coefficients nu(n) are observed for n = 1, 2, and 3, but they are very small for n > 3. These coefficients are expected to result in a ridge for correlations between two independently produced jets. The correlations between the orientation of the nth-order anisotropy induced by jet absorption (Phi(QP)(n)) and the nth-order participant plane (Phi(PP)(n)) responsible for harmonic flow are studied. Tight correlations are observed for n = 2 in mid-central collisions, but they weaken significantly for n not equal 2. The correlations are positive for n <= 3, but become negative in central collisions for n > 3. The dispersion between Phi(QP)(n) and Phi(PP)(n) is expected to break the factorization of the Fourier coefficients from two-particle correlation nu(n, n) into the single particle nu(n), and has important implications for the high-p(T) ridge phenomena.

The Standard Model (SM) fermions do not carry U(1) charges, but induced couplings to the Z' (called the dark Z) are generated through mixing with the SM neutral gauge bosons. Such a light Z' could explain some astrophysical anomalies as well as the muon g - 2 deviation, and has been the subject of great experimental interest. We consider the scenario in which the 125 GeV SM-like Higgs (H) is the heavier scalar state, and focus on the lighter neutral state (h) as well as charged Higgs. We analyze the constraints on the model from various experiments and predict novel channels to search for these Higgs scalars at the LHC. In particular, experiments looking for lepton jets are among potentially important searches. C1 [Lee, Hye-Sung; Sher, Marc] Coll William & Mary, Dept Phys, Williamsburg, VA 23187 USA.

We have studied these decays in a constituent quark model, which has been successful in describing semileptonic and nonleptonic B decays into orbitally excited charmed mesons. Our results do not confirm the hypothesis of large branching ratios for the B -> D'(()*()) semileptonic decays. In addition, we calculate the nonleptonic B -> D'pi decays which can provide an independent test of the form factors involved in the B -> D'(()*()) reactions.

The approach is based on a recently proposed Lagrangian-Green's function method that allows an efficient and accurate integration of the parallel (i.e., along the magnetic field) heat transport equation. The magnetic field lines are described by a nontwist Hamiltonian system, known to exhibit separatrix reconnection and robust shearless (dq/dr = 0) transport barriers. The changes in the magnetic field topology due to separatrix reconnection lead to bifurcations in the equilibrium temperature distribution. For perturbations of moderate amplitudes, magnetic chaos is restricted to bands flanking the shearless region. As a result, the temperature flattens in the chaotic bands and develops a very sharp radial gradient at the shearless region. For perturbations with larger amplitude, shearless Cantori (i.e., critical magnetic surfaces located at the minimum of the q profile) give rise to anomalous temperature relaxation involving widely different time scales. The first stage consists of the relatively fast flattening of the radial temperature profile in the chaotic bands with negligible flux across the shearless region that, for practical purposes, on a short time scale acts as an effective transport barrier despite the lack of magnetic flux surfaces. In the long-time scale, heat starts to flow across the shearless region, albeit at a comparatively low rate. The transport of a narrow temperature pulse centered at the reversed shear region exhibits weak self-similar scaling with non-Gaussian scaling functions indicating that transport at this scale cannot be modeled as a diffusive process with a constant diffusivity. Evidence of nonlocal effective radial transport is provided by the existence of regions with nonzero heat flux and zero temperature gradient. Parametric flux-gradient plots exhibit multivalued loops that question the applicability of the Fourier-Fick's prescription even in the presence of a finite pinch velocity.

One of the phases in this system can be mapped to Baxter's three-coloring problem, offering an easily accessible physical realization of this problem. As a function of temperature and interaction strength, we find a series of phases, including long range ordered loop or stripe states, stripes with sliding symmetries, random packed loop states, and disordered states in which the loops break apart. Our geometry could be constructed using ion trap arrays, BEC vortices in optical traps, or magnetic vortices in nanostructured superconductors.

TI Wave packet spreading and localization in electron-nuclear scattering SO PHYSICAL REVIEW E LA English DT Article ID MOLECULAR-DYNAMICS SIMULATIONS; SCHRODINGER-EQUATION; EXTREME CONDITIONS; DENSE MATTER; LARGE-SCALE; HYDROGEN; PLASMAS; FORMULATION; POTENTIALS; SYSTEM AB The wave packet molecular dynamics (WPMD) method provides a variational approximation to the solution of the time-dependent Schrodinger equation. Its application in the field of high-temperature dense plasmas has yielded diverging electron width (spreading), which results in diminishing electron-nuclear interactions. Electron spreading has previously been ascribed to a shortcoming of the WPMD method and has been counteracted by various heuristic additions to the models used. We employ more accurate methods to determine if spreading continues to be predicted by them and how WPMD can be improved. A scattering process involving a single dynamic electron interacting with a periodic array of statically screened protons is used as a model problem for comparison. We compare the numerically exact split operator Fourier transform method, the Wigner trajectory method, and the time-dependent variational principle (TDVP). Within the framework of the TDVP, we use the standard variational form of WPMD, the single Gaussian wave packet (WP), as well as a sum of Gaussian WPs, as in the split WP method. Wave packet spreading is predicted by all methods, so it is not the source of the unphysical diminishing of electron-nuclear interactions in WPMD at high temperatures. Instead, the Gaussian WP's inability to correctly reproduce breakup of the electron's probability density into localized density near the protons is responsible for the deviation from more accurate predictions. Extensions of WPMD must include a mechanism for breakup to occur in order to yield dynamics that lead to accurate electron densities.

Here the reproducible, giant light amplification in multiscale plasmonic structures is demonstrated. These structures combine strongly coupled components of different dimensions and topologies that resonate at the same optical frequency. A light amplifier is constructed using a silver mirror carrying light-enhancing surface plasmons, dielectric gratings forming distributed Bragg cavities on top of the mirror, and gold nanoparticle arrays self-assembled into the grating grooves. By tuning the resonances of the individual components to the same frequency, multiple enhancement of the light intensity in the nanometer gaps between the particles is achieved. Using a monolayer of benzenethiol molecules on this structure, an average SERS enhancement factor < EF > approximate to 108 is obtained, and the maximum enhancement in the interparticle hot-spots is approximate to 3 x 1010, in good agreement with FDTD calculations. The high enhancement factor, large density of well-ordered hot-spots, and good fidelity of the SERS signal make this design a promising platform for quantitative SERS sensing, optical detection, efficient solid state lighting, advanced photovoltaics, and other emerging photonic applications.

When a scientific application consisting of many subroutines is to be ported, the selection of key subroutines greatly impacts the productivity and overall porting strategy because these subroutines may represent a significant feature of the code in terms of functionality, code structure, or performance. They may as well serve as indicators of the difficulty and amount of effort involved in porting a code to a new platform. The proposed methodology is based on the idea that a set of similar subroutines can be ported with similar strategies and result in a similar-quality porting. By viewing subroutines as data and operator sequences, analogous to DNA sequences, we are able to use various bioinformatics techniques to conduct the similarity analysis of subroutines while mitigating NP-complete challenges of other approaches. To the best of our knowledge, we are one of the first to explore this bio-inspired view of program to target the porting planning problem. In this paper, we describe our methodology and present a tool called Klonos to facilitate the execution of the methodology, which integrates to well known bioinformatics tools. As a proof of concept, we use Klonos to conduct experiments to find strategies for porting of several scientific benchmarks and applications. We also have identified some of the advantages and limitations of the bio-inspired view of a program code and the future work. Copyright (c) 2012 John Wiley & Sons, Ltd.

TI Predicting the influence of pore characteristics on ductility of thin-walled high pressure die casting magnesium SO MATERIALS SCIENCE AND ENGINEERING A-STRUCTURAL MATERIALS PROPERTIES MICROSTRUCTURE AND PROCESSING LA English DT Article DE Mg castings; Ductility; Microstructure; Pore size; Pore volume fraction; Finite element analysis (FEA) ID TENSILE PROPERTIES; MG-ALLOY; AM50; MICROSTRUCTURE; SCALE; VARIABILITY; PLASTICITY; STRENGTH; BEHAVIOR; POROSITY AB In this paper, a two-dimensional microstructure-based finite element modeling method is adopted to investigate the effects of porosity in thin-walled high pressure die casting Mg materials on their ductility. For this purpose, the cross-sections of AM50 and AM60 casting samples are first examined using optical microscope to obtain the overall information on the pore characteristics. The experimentally quantified pore characteristics are then used to generate a series of synthetic microstructures with different pore sizes, pore volume fractions and pore size distributions. Pores are explicitly represented in the synthetic microstructures and meshed out for the subsequent finite element analysis. In the finite element analysis, an intrinsic critical strain value is used for the Mg matrix material, beyond which work-hardening is no longer permissible. With no artificial failure criterion prescribed, ductility levels are predicted for the various microstructures in the form of strain localization. Mesh size effect study is also conducted, from which a mesh size dependent critical strain curve is determined. A concept of scalability of pore size effects is then presented and examined with the use of the mesh size dependent critical strain curve. The results in this study show that, for the regions with lower pore size and lower volume fraction, the ductility generally decreases as the pore size and pore volume fraction increase whereas, for the regions with larger pore size and larger pore volume fraction, other factors such as the mean distance between the pores begin to have some substantial influence on the ductility. The results also indicate that the pore size effects may be scalable for the models with good-representative pore shape and distribution with the use of the mesh size dependent critical strain curve.

TI Discovery of diversity in xylan biosynthetic genes by transcriptional profiling of a heteroxylan containing mucilaginous tissue SO FRONTIERS IN PLANT SCIENCE LA English DT Article DE xylan; psyllium; secondary cell wall; irx; glycosyltransferase; mucilage ID SECONDARY CELL-WALL; CELLULOSE SYNTHASE COMPLEXES; ARABIDOPSIS SEED COAT; GLUCURONOXYLAN BIOSYNTHESIS; O-ACETYLATION; POLYSACCHARIDE BIOSYNTHESIS; UDP-ARABINOFURANOSE; FAMILY; PROTEINS; IDENTIFICATION AB The exact biochemical steps of xylan backbone synthesis remain elusive. In Arabidopsis, three non-redundant genes from two glycosyltransferase (GT) families, IRX9 and IRX14 from GT43 and IRX10 from GT47, are candidates for forming the xylan backbone. In other plants, evidence exists that different tissues express these three genes at widely different levels, which suggests that diversity in the makeup of the xylan synthase complex exists. Recently we have profiled the transcripts present in the developing mucilaginous tissue of psyllium (Plantago ovata Forsk). This tissue was found to have high expression levels of an IRX10 homolog, but very low levels of the two GT43 family members. This contrasts with recent wheat endosperm tissue profiling that found a relatively high abundance of the GT43 family members. We have performed an in-depth analysis of all GTs genes expressed in four developmental stages of the psyllium mucilagenous layer and in a single stage of the psyllium stem using RNA-Seq. This analysis revealed several IRX10 homologs, an expansion in GT61 (homologs of At3g18170/At3g18180), and several GTs from other GT families that are highly abundant and specifically expressed in the mucilaginous tissue. Our current hypothesis is that the four IRX10 genes present in the mucilagenous tissues have evolved to function without the GT43 genes. These four genes represent some of the most divergent IRX10 genes identified to date. Conversely, those present in the psyllium stem are very similar to those in other eudicots. This suggests these genes are under selective pressure, likely due to the synthesis of the various xylan structures present in mucilage that has a different biochemical role than that present in secondary walls. The numerous GT61 family members also show a wide sequence diversity and may be responsible for the larger number of side chain structures present in the psyllium mucilage.

TI Improved iron gettering of contaminated multicrystalline silicon by high-temperature phosphorus diffusion SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID SOLAR-CELLS; CARRIER LIFETIME; IMPURITIES; MECHANISMS; SI AB The efficacy of higher-temperature gettering processes in reducing precipitated iron concentrations is assessed by synchrotron-based micro-X-ray fluorescence. By measuring the same grain boundary before and after phosphorus diffusion in a set of wafers from adjacent ingot heights, the reduction in size of individual precipitates is measured as a function of gettering temperature in samples from the top of an ingot intentionally contaminated with iron in the melt. Compared to a baseline 820 degrees C phosphorus diffusion, 870 degrees C and 920 degrees C diffusions result in a larger reduction in iron-silicide precipitate size. Minority carrier lifetimes measured on wafers from the same ingot heights processed with the same treatments show that the greater reduction in precipitated metals is associated with a strong increase in lifetime. In a sample contaminated with both copper and iron in the melt, significant iron gettering and complete dissolution of detectable copper precipitates is observed despite the higher total metal concentration. Finally, a homogenization pre-anneal in N-2 at 920 degrees C followed by an 820 degrees C phosphorus diffusion produces precipitate size reductions and lifetimes similar to an 870 degrees C phosphorus diffusion without lowering the emitter sheet resistance.

TI Microstructure evolution during the isostructural decomposition of TiAlN-A combined in-situ small angle x-ray scattering and phase field study SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID SPINODAL DECOMPOSITION; THIN-FILMS; TI-AL; MECHANICAL-PROPERTIES; N COATINGS; TEMPERATURE; TI1-XALXN; DEPOSITION; SYSTEM; ALUMINUM AB This paper describes details of the spinodal decomposition and coarsening in metastable cubic Ti0.33Al0.67N and Ti0.50Al0.50N coatings during isothermal annealing, studied by in-situ small angle x-ray scattering, in combination with phase field simulations. We show that the isostructural decomposition occurs in two stages. During the initial stage, spinodal decomposition, of the Ti0.50Al0.50N alloy, the phase separation proceeds with a constant compositional wavelength of similar to 2.8 nm of the AlN-and TiN-rich domains. The time for spinodal decomposition depends on annealing temperature as well as alloy composition. After the spinodal decomposition, the coherent cubic AlN- and TiN-rich domains coarsen. The coarsening rate is kinetically limited by diffusion, which allowed us to estimate the diffusivity and activation energy of the metals to 1.4 x 10(-6) m(2) s(-1) and 3.14 eV at(-1), respectively.

TI Coil optimization for electromagnetic levitation using a genetic like algorithm SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID METALS; DENSITY; DESIGN; ALLOYS; SOLIDIFICATION; CALORIMETRY; TEMPERATURE; NETWORK; AU; FE AB The technique of electromagnetic levitation (EML) provides a means for thermally processing an electrically conductive specimen in a containerless manner. For the investigation of metallic liquids and related melting or freezing transformations, the elimination of substrate-induced nucleation affords access to much higher undercooling than otherwise attainable. With heating and levitation both arising from the currents induced by the coil, the performance of any EML system depends on controlling the balance between lifting forces and heating effects, as influenced by the levitation coil geometry. In this work, a genetic algorithm is developed and utilized to optimize the design of electromagnetic levitation coils. The optimization is targeted specifically to reduce the steady-state temperature of the stably levitated metallic specimen. Reductions in temperature of nominally 70K relative to that obtained with the initial design are achieved through coil optimization, and the results are compared with experiments for aluminum. Additionally, the optimization method is shown to be robust, generating a small range of converged results from a variety of initial starting conditions. While our optimization criterion was set to achieve the lowest possible sample temperature, the method is general and can be used to optimize for other criteria as well. (C) 2013 AIP Publishing LLC.

TI Role of internal gases and creep of Ag in controlling the critical current density of Ag-sheathed Bi2Sr2CaCu2Ox wires SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID SUPERCONDUCTING TAPES; BI-2212 TAPES; MELT PROCESS; SILVER; DEFORMATION; FABRICATION; TECHNOLOGY; CONDUCTORS; CARBON; LENGTH AB High engineering critical current density J(E) of > 500 A/mm(2) at 20 T and 4.2K can be regularly achieved in Ag-sheathed multifilamentary Bi(2)Sr(2)CaCu(2)Ox (Bi-2212) round wire when the sample length is several centimeters. However, J(E)(20 T) in Bi-2212 wires of several meters length, as well as longer pieces wound in coils, rarely exceeds 200 A/mm(2). Moreover, long-length wires often exhibit signs of Bi-2212 leakage after melt processing that are rarely found in short, open-end samples. We studied the length dependence of J(E) of state-of-the-art powder-in-tube (PIT) Bi-2212 wires and gases released by them during melt processing using mass spectroscopy, confirming that J(E) degradation with length is due to wire swelling produced by high internal gas pressures at elevated temperatures [A. Malagoli et al. Supercond. Sci. Technol. 24, 075016 (2011) and A. Malagoli et al. Supercond. Sci. Technol. 26, 055018 (2013)]. We further modeled the gas transport in Bi-2212 wires and examined the wire expansion at critical stages of the melt processing of as-drawn PIT wires and the wires that received a degassing treatment or a cold-densification treatment before melt processing. These investigations showed that internal gas pressure in long-length wires drives creep of the Ag sheath during the heat treatment, causing wire to expand, lowering the density of Bi-2212 filaments, and therefore degrading the wire JE; the creep rupture of silver sheath naturally leads to the leakage of Bi-2212 liquid. Our work shows that proper control of such creep is the key to preventing Bi-2212 leakage and achieving high JE in long-length Bi-2212 conductors and coils. (C) 2013 AIP Publishing LLC.

To gain insight into the experiments and assess how accurately the material's strength at pressure can be determined, finite element simulations of DAC experiments are performed. In the analyses, constitutive responses are assumed for the diamonds and the vanadium test specimen; within the constitutive models, the pressure dependence of the strength is prescribed. The quantities typically measured during experiments are extracted from the simulations and analyzed in an identical manner as the experimental data would be to obtain the pressure dependent flow strength. This computed pressure dependent strength is then compared with the prescribed input, allowing the accuracy and sensitivities of the experimental technique to be evaluated. Recommendations are made to improve the accuracy of strength determinations. (C) 2013 AIP Publishing LLC.

TI Thyroid Hormone Reverses Aging-Induced Myocardial Fatty Acid Oxidation Defects and Improves the Response to Acutely Increased Afterload SO PLOS ONE LA English DT Article ID C-13 ISOTOPOMER ANALYSIS; SUBSTRATE METABOLISM; HEART-FAILURE; RAT-HEART; CARDIAC-FUNCTION; FAILING HEART; ACETYL-COA; DYSFUNCTION; DISEASE; CARDIOMYOPATHY AB Background: Subclinical hypothyroidism occurs during aging in humans and mice and may contribute to the development of heart failure. Aging also impairs myocardial fatty acid oxidation, causing increased reliance on flux through pyruvate dehydrogenase (PDH) to maintain function. We hypothesize that the metabolic changes in aged hearts make them less tolerant to acutely increased work and that thyroid hormone supplementation reverses these defects. Methods: Studies were performed on young (Young, 4-6 months) and aged (Old, 22-24 months) C57/BL6 mice at standard (50 mmHg) and high afterload (80 mmHg). Another aged group received thyroid hormone for 3 weeks (Old-TH, high afterload only). Function was measured in isolated working hearts along with substrate fractional contributions (Fc) to the citric acid cycle (CAC) using perfusate with C-13 labeled lactate, pyruvate, glucose and unlabeled palmitate and insulin. Results: Old mice maintained cardiac function under standard workload conditions, despite a marked decrease in unlabeled (presumably palmitate) Fc and relatively similar individual carbohydrate contributions. However, old mice exhibited reduced palmitate oxidation with diastolic dysfunction exemplified by lower -dP/dT. Thyroid hormone abrogated the functional and substrate flux abnormalities in aged mice. Conclusion: The aged heart shows diminished ability to increase cardiac work due to substrate limitations, primarily impaired fatty acid oxidation. The heart accommodates slightly by increasing efficiency through oxidation of carbohydrate substrates. Thyroid hormone supplementation in aged mice significantly improves cardiac function potentially through restoration of fatty acid oxidation.

TI Reduced Incidence of Cardiac Arrhythmias in Walkers and Runners SO PLOS ONE LA English DT Article ID LONE ATRIAL-FIBRILLATION; HEART-DISEASE RISK; OF-SPORTS-MEDICINE; PHYSICAL-ACTIVITY; FOLLOW-UP; VIGOROUS EXERCISE; PUBLIC-HEALTH; OLDER-ADULTS; MEN; WALKING AB Purpose: Walking is purported to reduce the risk of atrial fibrillation by 48%, whereas jogging is purported to increase its risk by 53%, suggesting a strong anti-arrhythmic benefit of walking over running. The purpose of these analyses is to compare incident self-reported physician-diagnosed cardiac arrhythmia to baseline energy expenditure (metabolic equivalent hours per day, METhr/d) from walking, running and other exercise. Methods: Proportional hazards analysis of 14,734 walkers and 32,073 runners. Results: There were 1,060 incident cardiac arrhythmias (412 walkers, 648 runners) during 6.2 years of follow-up. The risk for incident cardiac arrhythmias declined 4.4% per baseline METhr/d walked by the walkers, or running in the runners (P = 0.0001). Specifically, the risk declined 14.2% (hazard ratio: 0.858) for 1.8 to 3.6 METhr/d, 26.5% for 3.6 to 5.4 METhr/d, and 31.7% for >= 5.4 METhr/d, relative to <1.8 METhr/d. The risk reduction per METhr/d was significantly greater for walking than running (P < 0.01), but only because walkers were at 34% greater risk than runners who fell below contemporary physical activity guideline recommendations; otherwise the walkers and runners had similar risks for cardiac arrhythmias. Cardiac arrhythmias were unrelated to walking and running intensity, and unrelated to marathon participation and performance. Conclusions: The risk for cardiac arrhythmias was similar in walkers and runners who expended comparable METhr/d during structured exercise. We found no significant risk increase for self-reported cardiac arrhythmias associated with running distance, exercise intensity, or marathon participation. Rhythm abnormalities were based on self-report, precluding definitive categorization of the nature of the rhythm disturbance. However, even if the runners' arrhythmias include sinus bradycardia due to running itself, there was no increase in arrhythmias with greater running distance.

Intracellular fluctuations originate from two sources: intrinsic noise due to the probabilistic nature of biochemical reactions and extrinsic noise due to randomized interactions of the cell with other cellular systems or its environment. Presently, there is no systematic parameterization and modeling scheme to simulate cellular response at the single cell level in the presence of extrinsic noise. Results: In this paper, we propose a novel statistical ensemble method to simulate the distribution of heterogeneous cellular responses in single cells. We capture the effects of extrinsic noise by randomizing values of the model parameters. In this context, a statistical ensemble is a large number of system replicates, each with randomly sampled model parameters from biologically feasible intervals. We apply this statistical ensemble approach to the well-studied NF-kappa B signaling system. We predict several characteristic dynamic features of NF-kappa B response distributions; one of them is the dosage-dependent distribution of the first translocation time of NF-kappa B. Conclusion: The distributions of heterogeneous cellular responses that our statistical ensemble formulation generates reveal the effect of different cellular conditions, e.g., effects due to wild type versus mutant cells or between different dosages of external stimulants. Distributions generated in the presence of extrinsic noise yield valuable insight into underlying regulatory mechanisms, which are sometimes otherwise hidden.

TI Sphingolipid Domains in the Plasma Membranes of Fibroblasts Are Not Enriched with Cholesterol SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID ION MASS-SPECTROMETRY; LIPID-MEMBRANES; INFLUENZA-VIRUS; PROTEINS; CELLS; RAFTS; ACTIN; HEMAGGLUTININ; ORGANIZATION; ADHESION AB The plasma membranes of mammalian cells are widely expected to contain domains that are enriched with cholesterol and sphingolipids. In this work, we have used high-resolution secondary ion mass spectrometry to directly map the distributions of isotope-labeled cholesterol and sphingolipids in the plasma membranes of intact fibroblast cells. Although acute cholesterol depletion reduced sphingolipid domain abundance, cholesterol was evenly distributed throughout the plasma membrane and was not enriched within the sphingolipid domains. Thus, we rule out favorable cholesterol-sphingolipid interactions as dictating plasma membrane organization in fibroblast cells. Because the sphingolipid domains are disrupted by drugs that depolymerize the cells actin cytoskeleton, cholesterol must instead affect the sphingolipid organization via an indirect mechanism that involves the cytoskeleton.

We study the changes of clustered Pd atoms under oxidizing and reducing (O-2 and CO, respectively) conditions in situ using ambient pressure XPS. The behavior of Pd in the clusters is quite different from that of Pd foil under the same conditions. For all Pd clusters, we observe only one Pd peak. The binding energy of this Pd 3d peak is similar to 1-1.4 eV higher than that of metallic Pd species and changes slightly in CO and O-2 environments. On the Pd foil however many different Pd species co-exist on the surface and change their oxidation states under different conditions. We find that the Pd atoms in direct contact with Al2O3 differ in oxidation state from the surface Pd atoms in a foil under reaction conditions. Compared to previous literature, we find that Pd 3d peak positions are greatly influenced by the different types of Al2O3 supports due to the combination of both initial and final state effects.

TI Evaluation of coarse-grained mapping schemes for polysaccharide chains in cellulose SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID MOLECULAR-DYNAMICS SIMULATIONS; NEUTRON FIBER DIFFRACTION; HYDROGEN-BONDING SYSTEM; SYNCHROTRON X-RAY; BIOMOLECULAR SYSTEMS; CRYSTAL-STRUCTURE; HIGHLY EFFICIENT; MODEL; PRETREATMENT; ALGORITHMS AB A fundamental understanding of the intermolecular forces that bind polysaccharide chains together in cellulose is crucial for designing efficient methods to overcome the recalcitrance of lignocellulosic biomass to hydrolysis. Because the characteristic time and length scales for the degradation of cellulose by enzymatic hydrolysis or chemical pretreatment span orders of magnitude, it is important to closely integrate the molecular models used at each scale so that, ultimately, one may switch seamlessly between quantum, atomistic, and coarse-grained descriptions of the system. As a step towards that goal, four multiscale coarse-grained models for polysaccharide chains in a cellulose-I alpha microfiber are considered. Using the force matching method, effective coarse-grained forces are derived from all-atom trajectories. Performance of the coarse-grained models is evaluated by comparing the intrachain radial distribution functions with those obtained using the all-atom reference data. The all-atom simulation reveals a double peak in the radial distribution function for sites within each glucose residue that arises from the distinct conformations sampled by the primary alcohol group in the glucose residues. The three-site and four-site coarse-grained models have sufficient degrees of freedom to predict this double peak while the one-site and two-site models do not. This is the first time that coarse-grained models have been shown to reproduce such subtle, yet important, molecular features in a polysaccharide chain. The relative orientations between glucose residues along the polysaccharide chain are evaluated and it is found that the four-site coarse-grained model is best at reproducing the glucose-glucose conformations observed in the all-atom simulation. The success of the four-site coarse-grained model underscores the importance of decoupling the pyranose ring from the oxygen atom in the glycosidic bond when developing all-atom to coarse-grained mapping schemes for polysaccharides.

D-2 also shows liquidlike diffusion while H-2 exhibits Chudley-Elliott jump diffusion, evidence of their different relationships with the local lattice of adsorption sites due to quantum effects on intermolecular interactions. The onset of diffusion occurs at 22-25 K for H-2 and 10-13 K for D-2. At these temperatures, H-2 and D-2 have identical thermal de Broglie wavelengths that correlate with the dominant pore size.

TI Nuclear structure of S-30 and its implications for nucleosynthesis in classical novae SO PHYSICAL REVIEW C LA English DT Article ID THERMONUCLEAR REACTION-RATES; PRESOLAR GRAINS; DECAY; RATIOS; STATES; DISTRIBUTIONS; ELEMENTS; PHYSICS; SHELL AB Background: The uncertainty in the P-29(p, gamma)S-30 reaction rate over 0.1 <= T <= 1.3 GK was previously determined to span approximately four orders of magnitude due to the uncertain location of two previously unobserved 3(+) and 2(+) resonances in the E-x = 4.7-4.8 MeV region in S-30. Therefore, the abundances of silicon isotopes synthesized in novae, which are relevant for the identification of presolar grains of putative nova origin, were uncertain by a factor of 3. Purpose: (a) To investigate the level structure of S-30 above the proton threshold [4394.9(7) keV] via charged-particle spectroscopy using the S-32(p, t) S-30 reaction and in-beam gamma-ray spectroscopy using the Si-28(He-3, n gamma)S-30 reaction to calculate the P-29(p, gamma)S-30 reaction rate. (b) To explore the impact of this rate on the abundances of silicon isotopes synthesized in novae. Methods: Differential cross sections of the S-32(p, t)S-30 reaction were measured at 34.5 MeV. Distorted-wave Born approximation calculations were performed to constrain the spin-parity assignments of the observed levels, including the two astrophysically-important levels. An energy-level scheme was deduced from gamma-gamma coincidence measurements using the Si-28(He-3, n gamma)S-30 reaction. Spin-parity assignments based on measurements of gamma-ray angular distributions and gamma-gamma directional correlation from oriented nuclei were made for most of the observed levels of S-30. Results: The resonance energies corresponding to the states with 4.5 MeV less than or similar to E-x less than or similar to 6 MeV, including the two astrophysically important states predicted previously, are measured with significantly better precision than before. The spin-parity assignments of both astrophysically important resonances are confirmed. The uncertainty in the rate of the P-29(p, gamma)S-30 reaction is substantially reduced over the temperature range of interest. Finally, the influence of this rate on the abundance ratios of silicon isotopes synthesized in novae are obtained via 1D hydrodynamic nova simulations. Conclusions: The uncertainty in the P-29(p, gamma)S-30 reaction rate is reduced to the point that it no longer affects the silicon isotopic abundance ratios significantly, and, thus, the results of our nova hydrodynamic simulation for the nucleosynthesis in the Si-Ca mass region are more reliable than before.

As organic polymers, epoxy thermo-sets and composite materials will degrade under thermo-oxidative conditions with loss of useful properties in adhesion or mechanical toughness, and this degradation may initiate at the surface. While high temperature empirical data on the depth of degradation profiles have been made available for some materials, precise data on the intrinsic oxidation sensitivity of epoxy materials do not yet exist. Two different epoxy material types were chosen: a DGEBA based resin (Epon 828) was cured with either a cycloaliphatic amine (Ancamine 2049) or a polyether amine (Jeffamine D230) for comparison. Due to generally low O-2 permeability in epoxies any oxidation will be limited to the surface; hence experiments were conducted for thin films under non-diffusion limited conditions to obtain unbiased rate data. We have succeeded to show for the first time that oxidation behavior of epoxies at moderate temperatures can be approached experimentally. This study offers an overview on the intrinsic oxidation sensitivity of two cured epoxy thermo-set materials between 25 and 140 degrees C. Excellent Arrhenius behavior was observed with activation energies in the 70-80 kJ/mol range. These epoxy materials are surprisingly reactive and show higher oxidation rates than anticipated, even at moderate temperatures. In any applications where epoxy materials are used at elevated temperatures under non-inert conditions, oxidation will result in material chemistry changes and this will affect their performance with regard to adhesion or properties in composites.

A solution NMR method of the dissolved cellulose was used to determine that this bacterial cellulose had 85% deuterium incorporation. Acetylation and H-1 and H-2 NMR of deuterated bacterial cellulose indicated near equal deuteration at all sites of the glucopyranosyl ring except C-6 which was partly deuterated. Despite the high level of deuterium incorporation no significant differences in the molecular and morphological properties were observed for the deuterated and protio bacterial cellulose samples. The highly deuterated bacterial cellulose presented here can be used as a model substrate for studying cellulose biopolymer properties via future small angle neutron scattering (SANS) studies.

Over this temperature range, magnesium was released congruently with respect to silica. The effect of variable pCO2 levels representative of engineered geothermal systems with CO2 as a heat-exchanging fluid (CO2-EGS) was explored by reacting chlorite with solutions containing a range of dissolved CO2 concentrations (0.1-0.5 M). The dissolution rate was insensitive to CO2(aq) concentration, with dissolved CO2 apparently affecting dissolution only through increased acidity. Over this range of far-from-equilibrium experimental conditions of elevated temperature, mildly acidic to moderately neutral pH, and CO2(aq) concentrations up to 0.5 M, Mg-rich chlorite dissolution can be described as a surface area-normalized rate equal to: rate = k(acid) exp [(-E-acid/R).( 1/T - 1/298K)].a(H+1)(n) where the apparent acid rate constant at 25 degrees C is k(a) =10(-9-91) mol m(-2) s(-1), the reaction order n with respect to H+(aq) is 0.49, and the activation energy for the acid mechanism is E = 25.1 kJ mol(-1) (this value is significantly lower than previous estimates). This chlorite dissolution rate equation can be used with reaction affinity terms and kinetic laws for other minerals to estimate the impact of geochemical alteration within CO2-enhanced geothermal system operations or other higher-temperature subsurface systems. Over a 100-275 degrees C temperature range, chlorite is 2-5 orders of magnitude less reactive than has been previously predicted. (C) 2013 Elsevier B.V. All rights reserved.

Molecular hydrogen is the dominant gaseous radiolysis product from these ionic liquids, and the yields with gamma-rays are 0.73 and 0.098 molecules per 100 eV of energy absorbed for [N-1114][Tf2N] and [emim][Tf2N], respectively. These low yields are consistent with the relative insensitivity of most aromatic compounds to radiation. However, the molecular hydrogen yields increase considerably on going from gamma-rays to protons to helium ions with [emim][Tf2N] while they remain essentially constant for [N-1114][Tf2N). FTIR and UV-vis spectroscopic studies show slight degradation of the ionic liquids with radiation.

The optically dark nature of their active sites usually prevents a complete mapping of the photoinduced dynamics. In this work, transient X-ray absorption spectroscopy highlights the electronic and geometric changes that affect such a center in a bimetallic model complex. Upon selective excitation of the ruthenium chromophore, the cobalt moiety is reduced through intramolecular electron transfer and undergoes a spin flip accompanied by an average bond elongation of 0.20 +/- 0.03 angstrom. The analysis is supported by simulations based on density functional theory structures (B3LYP*/TZVP) and FEFF 9.0 multiple scattering calculations. More generally, these results exemplify the large potential of the technique for tracking elusive intermediates that impart unique functionalities in photochemical devices.

There is evidence for hippocampal neurogenesis in adult humans, although whether its extent is sufficient to have functional significance has been questioned. We have assessed the generation of hippocampal cells in humans by measuring the concentration of nuclearbomb-test-derived C-14 in genomic DNA, and we present an integrated model of the cell turnover dynamics. We found that a large subpopulation of hippocampal neurons constituting one-third of the neurons is subject to exchange. In adult humans, 700 new neurons are added in each hippocampus per day, corresponding to an annual turnover of 1.75% of the neurons within the renewing fraction, with a modest decline during aging. We conclude that neurons are generated throughout adulthood and that the rates are comparable in middle-aged humans and mice, suggesting that adult hippocampal neurogenesis may contribute to human brain function.

Concurrently, understanding how chirality affects these processes has become a critical challenge for various applications in the pharmaceutical and food industries ranging from drug catalysis to novel sensing. Here, we present a unique way of transferring the chirality of simple amino acids, L- and D-alanine, to large-scale chiral networks on Cu(111). We further utilize the unique geometry of the chiral network as a scaffolding to isolate individual molecules within a 1.2 nm hexagonal pore. These hexagonal pores act as single molecule "race tracks" where excess alanine molecules trapped at the perimeter are observed to hop between six distinct locations around the perimeter. Scanning tunneling microscopy (STM) as well as density functional theory (DFT) calculations have been utilized to directly track, influence, and probe this molecular motion confined to self-assembled, chiral, hexagonal pores which also form quantum corrals.

One of the interests in this system is in connecting the highly quantum-mechanical spin-1 phase diagram with the classical S = infinity phase diagram. Several of the recent advances within DMRG make it possible to perform a detailed analysis of the whole phase diagram. We consider different types of on-site anisotropies, which allows us to establish the validity of the following statements: (1) the spin-2 model can be tuned into a phase, which is equivalent to the "topologically nontrivial" spin-1 Haldane phase, and (2) the spin-2 Haldane phase at the isotropic Heisenberg point is adiabatically connected to the "trivial" large-D phase, with a continuous change of the Hamiltonian parameters. Furthermore, we study the spin-3 XXZ chain to help explain the development of the classical phase diagram. We present details on how to use the iDMRG method to map out the phase diagram and include an extensive discussion of the numerical methods. C1 [Kjaell, Jonas A.; Zaletel, Michael P.; Mong, Roger S.

TI Parallel rf Force Driven by the Inhomogeneity of Power Absorption in Magnetized Plasma SO PHYSICAL REVIEW LETTERS LA English DT Article ID ENERGETIC ALPHA-PARTICLES; TOKAMAK PLASMAS; FLOW DRIVE; WAVES AB A nonlinear parallel force can be exerted through the inhomogeneity of rf resonant absorption in a magnetized plasma. While providing no integrated force over a plasma volume, this force can redistribute momentum parallel to the magnetic field. Because flows and currents parallel to the magnetic field encounter different resistances, this redistribution can play a large role, in addition to the role played by the direct absorption of parallel momentum. For nearly perpendicular propagating waves in a tokamak plasma, this additional force is expected to affect significantly the toroidal rf-driven current and the toroidal flow drive.

We show that with the presence of both vector and axial charge densities, the electric field can induce an axial current along its direction and thus cause chirality separation. We call it the chiral electric separation effect (CESE). On a very general basis, we argue that the strength of CESE is proportional to mu(V)mu(A) with mu(V) and mu(A) the chemical potentials for vector charge and axial charge. We then explicitly calculate this CESE conductivity coefficient in thermal QED at leading-log order. The CESE can manifest a new gapless wave mode propagating along the electric field. Potential observable effects of CESE in heavy-ion collisions are also discussed. C1 [Huang, Xu-Guang; Liao, Jinfeng] Indiana Univ, Dept Phys, Bloomington, IN 47408 USA.

Such a critical point requires a line of classical phase transitions terminating at zero temperature near optimal doping inside the superconducting 'dome'. The underdoped region of the temperature-doping phase diagram from which superconductivity emerges is referred to as the 'pseudogap'(7-13) because evidence exists for partial gapping of the conduction electrons, but so far there is no compelling thermodynamic evidence as to whether the pseudogap is a distinct phase or a continuous evolution of physical properties on cooling. Here we report that the pseudogap in YBa2Cu3O6+delta is a distinct phase, bounded by a line of phase transitions. The doping dependence of this line is such that it terminates at zero temperature inside the superconducting dome. From this we conclude that quantum criticality drives the strange metallic behaviour and therefore superconductivity in the copper oxide superconductors. C1 [Shekhter, Arkady; Ramshaw, B.

The materials produced, as measured by superconducting quantum interference device magnetometry, X-ray magnetic circular dichroism, Mossbauer spectroscopy, etc., show dramatic increases in coercivity with increasing cobalt content without a major decrease in overall saturation magnetization. Structural and magnetization analyses reveal a reduction in particle size to less than 4 nm at the highest Co content, combined with an increase in the effective anisotropy of the magnetic nanoparticles. The potential use of these biogenic nanoparticles in aqueous suspensions for magnetic hyperthermia applications is demonstrated. Further analysis of the distribution of cations within the ferrite spinel indicates that the cobalt is predominantly incorporated in octahedral coordination, achieved by the substitution of Fe2+ site with Co2+, with up to 17 per cent Co substituted into tetrahedral sites.

The final butyral group content (up to 84%) of PVB is found to be dependent strongly on the initial condensed state of PVA, the degree of polymerization of PVA, the purity and volume of ethanol, and the pH value. A maximum of butyral group content may be obtained under conditions: swollen PVA particles, (95 vol %) ethanol of 125-150 mL, and pH 1. This reverse dissolution approach has advantages such as a mild reaction condition (70 degrees C), no predissolution of PVA at high temperatures, no vacuum removal of water during reaction, and low water consumption in post-treatment of the product.

Keith Roentsch, Raoul TI Single top production in association with a Z boson at the LHC SO PHYSICAL REVIEW D LA English DT Article ID CHANGING NEUTRAL CURRENTS; QCD CORRECTIONS; COLLISIONS; COLLIDERS; INTEGRALS; SEARCH; DECAYS; MODEL; NLO AB We present results for the production of a Z boson in association with single top at next-to-leading order (NLO), including the decay of the top quark and the Z boson. This electroweak process gives rise to the trilepton signature l(+)l(-)l'(+/-) + jets + missing energy. We present results for this signature and show that the rate is competitive with the contribution of the mixed strong and electroweak production process, t (t) over barZ. As such it should be observable in the full data sample fromLHCrunning at root s = 8 TeV. The single top + Z process is a hitherto unconsidered irreducible background in searches for flavor changing neutral current decays of the top quark in t (t) over bar production. For a selection of cuts used at the LHC involving a b-tag it is the dominant background. In the Appendices we also briefly discuss the impact of NLO corrections on the related tH process.

CA BABAR Collaboration TI Search for B -> K-(*()) v(v)over-bar and invisible quarkonium decays SO PHYSICAL REVIEW D LA English DT Article AB We search for the flavor-changing neutral-current decays B -> K-(*()) v (v) over bar, and the invisible decays J/psi -> v (v) over bar and psi(2S) -> v (v) over bar via B -> K-(*())J/psi and B -> K-(*()) psi(2S), respectively, using a data sample of 471 x 10(6) B (B) over bar pairs collected by the BABAR experiment. We fully reconstruct the hadronBic decay of one of the B mesons in the Y(4S) -> B (B) over bar decay, and search for the B -> K-(*()) v (v) over bar decay in the rest of the event. We observe no significant excess of signal decays over background and report branching fraction upper limits of B(B+ -> K+ v (v) over bar) < 3.7 x 10(-5), B(B-0 -> K-0 v<(v)over bar>) < 8.1 x 10(-5), B(B+ -> K*(+) v<(v)over bar>) < 11.6 x 10(-5), B(B-0 -> K*(0) v<(v)over bar>), < 9.3 x 10(-5), and combined upper limits of B(B -> K v<(v)over bar>) < 3.2 x 10(-5) and B(B -> K* v<(v)over bar>) < 7.9 x 10(-5), all at the 90% confidence level. For the invisible quarkonium decays, we report branching fraction upper limits of B(J/psi -> v<(v)over bar>) < 3.9 x 10(-3) and B(psi(2S) -> v<(v)over bar> < 15.5 x 10(-3) at the 90% confidence level. Using the improved kinematic resolution achieved from hadronic reconstruction, we also provide partial branching fraction limits for the B -> K-(*()) v<(v)over bar> decays over the full kinematic spectrum.
