The predicted behavior indicates an isothermal linear dependence (a) between the magnitude of the average induced dipole moment mu(ind) and the average system density rho, (b) between the magnitude of the average induced dipole mu(ind) and that of the total dipole mu(tot), resulting from (c), a compensating (inverse) dependence between the permanent-to-induced dipolar angle theta and the magnitude of the average induced dipole moment mu(ind). Moreover, we interpret this behavior in terms of the evolution of the state dependent tetrahedral order parameter q(T) and the corresponding bond-order parameter Q(6), supplemented by the microstructural analysis based on the three site-site radial distribution functions of water and the distance-ranked nearest-neighbor distributions. Finally, we show that while water exhibits a dramatic microstructural transformation from an open four-coordinated hydrogen-bonded network at normal conditions to a quasi-close-packed coordination, it still preserves a significant degree of hydrogen bonding.

The heats of reaction and the chemical potential changes of these solids upon CO2 capture reactions have been calculated and used to evaluate the energy costs. Relative to CaO, a widely used system in practical applications, MgO and Mg(OH)(2) systems were found to be better candidates for CO2 sorbent applications due to their lower operating temperatures (600-700 K). In the presence of H2O, MgCO3 can be regenerated into Mg(OH)(2) at low temperatures or into MgO at high temperatures. This transition temperature depends not only on the CO2 pressure but also on the H2O pressure. Based on our calculated results and by comparing with available experimental data, we propose a general computational search methodology which can be used as a general scheme for screening a large number of solids for use as CO2 sorbents.

At 248 nm, the only dissociation products observed were from H atom loss, attributed primarily to H+o-C(6)H(4) (ortho-benzyne). The observed translational energy distribution was consistent with statistical decay on the ground state surface. At 193 nm, dissociation to H+C(6)H(4) and C(4)H(3)+C(2)H(2) was observed. The C(6)H(4) fragment can be either o-C(6)H(4) or l-C(6)H(4) resulting from decyclization of the phenyl ring. The C(4)H(3)+C(2)H(2) products dominate over the two H loss channels. Attempts to reproduce the observed branching ratio by assuming ground state dynamics were unsuccessful. However, these calculations assumed that the C(4)H(3) fragment was n-C(4)H(3), and better agreement would be expected if the lower energy i-C(4)H(3)+C(2)H(2) channel were included.

The joint inversion benefits from both better resolution and wider data coverage than when using only individual data sets. Resolution tests confirm that the joint inversion yields good resolution ranging from the Moho to a depth of 1400 km. The complementary and overlapping nature of the different data sets' resolving power has reduced disparities in resolving power that exist for individual data sets, for example between resolving power for crustal and lower-mantle structure. This increases the utility of the new tomographic model for explaining and predicting a variety of observations and dynamics. The new model derived from the joint inversion assembles a large number of mantle structures known from a wide variety of previous studies into one model and in some cases reconciles different local studies that previously seemed contradictory. Finally, the model shows that shallow low-velocity anomalies beneath the Pannonian basin and the Iranian plateau are connected to similar anomalies in the transition zone, the latter possibly related to a deep dehydration process in the subducted lithosphere of the Neo-Tethys Ocean. The model shows the Hellenic slab penetrating the lower mantle, the Calabrian slab extending flatly in the transition zone, and discontinuous slabs beneath the Apennines and the Zagros belt.

Using optical and infrared (RIYJHK) photometry, we derive a photometric redshift of 4.4 < z < 5.2; at this redshift our simultaneous multicolour observations begin at similar to 30 s after the gamma-ray burst trigger in the host frame, during the initial rising phase of the afterglow. We associate the light-curve peak at similar to 580 s in the observer frame with the formation of the forward shock, giving an estimate of the initial Lorentz factor Gamma(0) similar to 200. The red spectral energy distribution (even in regions not affected by the Lyman alpha break) provides secure evidence of a large dust column. However, the inferred extinction curve shows a prominent flat component between 2000 and 3000 A in the rest frame, inconsistent with any locally observed template but well fitted by models of dust formed by supernovae. Time-dependent fits to the extinction profile reveal no evidence of dust destruction and limit the decrease in the extinction column to delta A(3000) < 0.54 mag after t = 50 s in the rest frame. Together with studies of high-z quasars, our observations suggest a transition in dust properties in the early Universe, possibly associated with a transition between supernova-dominated and asymptotic giant branch-dominated modes of dust production.

One of the most likely sources of isotropic EM emission from compact object mergers is a supernova-like transient powered by the radioactive decay of heavy elements synthesized in ejecta from the merger. We present the first calculations of the optical transients from compact object mergers that self-consistently determine the radioactive heating by means of a nuclear reaction network; using this heating rate, we model the light curve with a one-dimensional Monte Carlo radiation transfer calculation. For an ejecta mass similar to 10-2 M(circle dot) (10-3 M(circle dot)) the resulting light-curve peaks on a time-scale similar to 1 d at a V-band luminosity nu L(nu) similar to 3 x 1041 (1041) erg s-1 [M(V) = -15(-14)]; this corresponds to an effective 'f' parameter similar to 3 x 10-6 in the Li-Paczynski toy model. We argue that these results are relatively insensitive to uncertainties in the relevant nuclear physics and to the precise early-time dynamics and ejecta composition. Since NS merger transients peak at a luminosity that is a factor of similar to 103 higher than a typical nova, we propose naming these events 'kilo-novae'. Because of the rapid evolution and low luminosity of NS merger transients, EM counterpart searches triggered by GW detections will require close collaboration between the GW and astronomical communities. NS merger transients may also be detectable following a short-duration gamma-ray burst or 'blindly' with present or upcoming optical transient surveys. Because the emission produced by NS merger ejecta is powered by the formation of rare r-process elements, current optical transient surveys can directly constrain the unknown origin of the heaviest elements in the Universe.

TI BINARY CONTAMINATION IN THE SEGUE SAMPLE: EFFECTS ON SSPP DETERMINATIONS OF STELLAR ATMOSPHERIC PARAMETERS SO ASTROPHYSICAL JOURNAL LA English DT Article DE astronomical databases: miscellaneous; binaries: general; stars: abundances; stars: luminosity function, mass function; surveys ID DIGITAL SKY SURVEY; INITIAL MASS FUNCTION; SOLAR-TYPE STARS; MILKY-WAY TOMOGRAPHY; G-DWARF; HIERARCHICAL-MODELS; LUMINOSITY FUNCTION; CHEMICAL EVOLUTION; OPEN CLUSTERS; DATA RELEASE AB We examine the effects that unresolved binaries have on the determination of various stellar atmospheric parameters for targets from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) using numerical modeling, a grid of synthetic spectra, and the SEGUE Stellar Parameter Pipeline (SSPP). The SEGUE survey, a component of the Sloan Digital Sky Survey-II (SDSS-II) project focusing on Galactic structure, provides medium resolution spectroscopy for over 200,000 stars of various spectral types over a large area on the sky. To model undetected binaries that may be in this sample, we use a variety of mass distributions for the primary and secondary stars in conjunction with empirically determined relationships for orbital parameters to determine the fraction of G-K dwarf stars, defined by SDSS color cuts as having 0.48 <= (g - r)(0) <= 0.75, that will be blended with a secondary companion. We focus on the G-K dwarf sample in SEGUE as it records the history of chemical enrichment in our galaxy. To determine the effect of the secondary on the spectroscopic parameters, specifically effective temperature, surface gravity, metallicity, and [alpha/Fe], we synthesize a grid of model spectra from 3275 to 7850 K and [Fe/H] = -0.5 to -2.5 from MARCS model atmospheres using TurboSpectrum. These temperature and metallicity ranges roughly correspond to a stellar mass range of 0.1-1.0M(circle dot). We assume that both stars in the pair have the same metallicity. We analyze both "infinite" signal-to-noise ratio (S/N) models and degraded versions of the spectra, at median S/N of 50, 25, and 10. By running individual and combined spectra (representing the binaries) through the SSPP, we determine that similar to 10% of the blended G-K dwarf pairs with S/N >= 25 will have their atmospheric parameter determinations, in particular temperature and metallicity, noticeably affected by the presence of an undetected secondary; namely, they will be shifted beyond the expected SSPP uncertainties. Shifts in [Fe/H] largely result from the shifts in temperature caused by a secondary. The additional uncertainty from binarity in targets with S/N >= 25 is similar to 80 K in temperature and similar to 0.1 dex in [Fe/H]. The effect on surface gravity and [alpha/Fe] is even smaller. As the S/N of targets decreases, the uncertainties from undetected secondaries increase. For S/N = 10, 40% of the G-K dwarf sample is shifted beyond expected uncertainties for this S/N in effective temperature and/or metallicity. To account for the additional uncertainty from binary contamination at an S/N similar to 10, the most extreme scenario, uncertainties of similar to 140 K and similar to 0.17 dex in [Fe/H] must be added in quadrature to the published uncertainties of the SSPP.

TI MEASUREMENTS OF SECONDARY COSMIC MICROWAVE BACKGROUND ANISOTROPIES WITH THE SOUTH POLE TELESCOPE SO ASTROPHYSICAL JOURNAL LA English DT Article DE cosmic background radiation; cosmological parameters; cosmology: observations; galaxies: clusters: intracluster medium; large-scale structure of universe ID ANGULAR POWER SPECTRUM; STAR-FORMING GALAXIES; EXTRAGALACTIC SOURCES; DUST EMISSION; CLUSTERS; PROBE; CMB; SUBMILLIMETER; CAMERA; TEMPERATURE AB We report cosmic microwave background (CMB) power-spectrum measurements from the first 100 deg(2) field observed by the South Pole Telescope (SPT) at 150 and 220 GHz. On angular scales where the primary CMB anisotropy is dominant, l less than or similar to 3000, the SPT power spectrum is consistent with the standard Lambda CDM cosmology. On smaller scales, we see strong evidence for a point-source contribution, consistent with a population of dusty, star-forming galaxies. After we mask bright point sources, anisotropy power on angular scales of 3000 < l < 9500 is detected with a signal-to-noise ratio greater than or similar to 50 at both frequencies. We combine the 150 and 220 GHz data to remove the majority of the point-source power and use the point-source-subtracted spectrum to detect Sunyaev-Zel'dovich (SZ) power at 2.6 sigma. At l = 3000, the SZ power in the subtracted bandpowers is 4.2 +/- 1.5 mu K-2, which is significantly lower than the power predicted by a fiducial model using WMAP5 cosmological parameters. This discrepancy may suggest that contemporary galaxy cluster models overestimate the thermal pressure of intracluster gas. Alternatively, this result can be interpreted as evidence for lower values of sigma(8). When combined with an estimate of the kinetic SZ contribution, the measured SZ amplitude shifts sigma(8) from the primary CMB anisotropy derived constraint of 0.794 +/- 0.028 down to 0.773 +/- 0.025. The uncertainty in the constraint on sigma(8) from this analysis is dominated by uncertainties in the theoretical modeling required to predict the amplitude of the SZ power spectrum for a given set of cosmological parameters.

This set of astrophysical data can be utilized with significant confidence in future astrochemical models of photon-dominated regions and also of the protoplanetary nebulae CRL 618. We recommend ionization energies of polyacetylenes from diacetylene up to heptaacetylene with an experimental accuracy of +/- 0.05 eV: 10.03 eV (diacetylene), 9.45 eV (triacetylene), 9.08 eV (tetraacetylene), 8.75 eV (pentaacetylene), 8.65 eV (hexaacetylene), and 8.50 eV (heptaacetylene). Further, ionization energies with an accuracy of +/- 0.1 eV: 8.32 eV (octaacetylene) and 8.24 eV (nonaacetylene), were computed. Implications of these energies to the redox chemistry involved in the multiply charged metal-ion mediated chemistry of hydrocarbon-rich atmospheres of planets and their moons such as Titan are also discussed.

In this paper, however, we show in detail, that, the correspondence between galaxy morphology and color is not perfect, providing insight into the physical origin of this evolution. Using the COSMOS survey, we study a significant population of red-sequence galaxies with disk-like morphologies. These passive disks typically have Sa-Sb morphological types with large bulges, but they are not confined to dense environments. They represent nearly one-half of all red-sequence galaxies and dominate at lower masses (less than or similar to 10(10) M(circle dot)) where they are increasingly disk-dominated. As a function of time, the abundance of passive disks with M(*) less than or similar to 10(11) M(circle dot) increases, but not as fast as red-sequence spheroidals in the same mass range. At higher mass, the passive disk population has declined since z similar to 1, likely because they transform into spheroidals. Based on these trends, we estimate that as much as 60% of galaxies transitioning onto the red sequence evolve through a passive disk phase. The origin of passive disks therefore has broad implications for our understanding of how star formation shuts down. Because passive disks tend to be more bulge-dominated than their star-forming counterparts, a simple fading of blue disks does not fully explain their origin. We explore the strengths and weaknesses of several more sophisticated explanations, including environmental effects, internal stabilization, and disk regrowth during gas-rich mergers. While previous work has sought to explain color and morphological transformations with a single process, these observations open the way to new insight by highlighting the fact that galaxy evolution may actually proceed through several separate stages.

SO ASTROPHYSICAL JOURNAL LA English DT Article DE ISM: clouds; ISM: kinematics and dynamics; ISM: magnetic fields; ISM: structure; plasmas; Sun: heliosphere ID INTERSTELLAR BOUNDARY EXPLORER; OUTER HELIOSPHERE; MAGNETIC-FIELD; SOLAR-CYCLE; PHYSICAL-PROPERTIES; TERMINATION SHOCK; LOCAL CLOUD; GAS; HYDROGEN; RIBBON AB The Interstellar Boundary Explorer (IBEX) spacecraft is providing the first all-sky maps of the energetic neutral atoms (ENAs) produced by charge exchange between interstellar neutral H degrees atoms and heliospheric solar wind and pickup ions in the heliosphere boundary regions. The "edge" of the interstellar cloud presently surrounding the heliosphere extends less than 0.1 pc in the upwind direction, terminating at an unknown distance, indicating that the outer boundary conditions of the heliosphere could change during the lifetime of the IBEX satellite. Using reasonable values for future outer heliosphere boundary conditions, ENA fluxes are predicted for one possible source of ENAs coming from outside of the heliopause. The ENA-production simulations use three-dimensional MHD plasma models of the heliosphere that include a kinetic description of neutrals and a Lorentzian distribution for ions. Based on this ENA-production model, it is then shown that the sensitivities of the IBEX 1.1 keV skymaps are sufficient to detect the variations in ENA fluxes that are expected to accompany the solar transition into the next upwind cloud. Approximately 20% of the IBEX 1.1 keV pixels appear capable of detecting the predicted model differences at the 3 sigma level, with these pixels concentrated in the Ribbon region. Regardless of the detailed ENA production model, the success of the modeled B . R similar to 0 directions in reproducing the Ribbon locus, together with our results, indicates that the Ribbon phenomenon traces the variations in the heliosphere distortion caused by the relative pressures of the interstellar magnetic and gaseous components.

This model is defined by maps of attenuation coefficient across the region of study in the period band 14-24 s. The model is constructed to characterize the regional variations in attenuation of seismic waves in the crust, which are related to the tectonic history of the studied territory, to calibrate the regional surface-wave magnitude scale, and to extend the teleseismic 'surface-wave magnitude - body wave magnitude' (Ms-mb) discriminant to regional distances. The construction of the model proceeds in three stages. The first stage in model construction is the measurement of Rayleigh wave spectral amplitudes. We collected and processed waveform data for 200 earthquakes occurring from 2003 to 2006 inside and around Eurasia, and used records of about 135 broadband permanent and temporary stations. This data set provided a sufficient number of spectral amplitude measurements between 14 and 24 s periods for the construction of two-dimensional tomographic maps of attenuation coefficients. At the second stage of the work, the integral of attenuation coefficients along given paths is estimated using both inter-station measurements and single-station measurements corrected for source and receiver terms. The third stage includes the refining of source parameters, recalculation of attenuation coefficient integrals after this refinement, grooming of resulting coefficients, and multistage tomographic inversion of the data. Tomographic maps for the set of periods from 14 to 24 s, which exhibit clear correlation with geology and tectonics of the territory under study, were obtained. Validation of these maps using the inter-station measurements confirms their accuracy in predicting the observations.

This energy balance between free electrons and phonons was first proposed in 1956 by Kaganov et al. but has recently been utilized as a framework for coupling molecular dynamics to a continuum description of electron transport. Using finite element domain decomposition techniques from our previous work as a basis, we develop a coupling scheme that preserves energy and has local control of temperature and energy flux via a Gaussian isokinetic thermostat. Unlike the previous work on this subject, we employ an efficient, implicit time integrator for the fast electron transport which enables larger stable time steps than the explicit schemes commonly used. A number of example simulations are given that validate the method, including Joule heating of a copper nanowire and laser excitation of a suspended carbon nanotube with its ends embedded in a conducting substrate.

In the EcoRV-cognate DNA crystallographic complex, a sharp kink of 50 has been found at the center base-pair step (TA). Here, we examine the interplay between the intrinsic propensity of the cognate sequence to kink and the induction by the enzyme by performing all-atom molecular dynamics simulations of EcoRV unbound and interacting with three DNA sequences: the cognate sequence, GATATC (TA); the non-cognate sequence, GAATTC (AT); and with the cognate sequence methylated on the first adenine GA(CH3) TATC (TA-CH(3)). In the unbound EcoRV, the cleft between the two C-terminal subdomains is found to be open. Binding to AT narrows the cleft and forms a partially bound state. However, the intrinsic bending propensity of AT is insufficient to allow tight binding. In contrast, the cognate TA sequence is easier to bend, allowing specific, high-occupancy hydrogen bonds to form in the complex. The absence of cleavage for this methylated sequence is found to arise from the loss of specific hydrogen bonds between the first adenine of the recognition sequence and Asn185. On the basis of the results, we suggest a three-step recognition mechanism. In the first step, EcoRV, in an open conformation, binds to the DNA at a random sequence and slides along it. In the second step, when the two outer base pairs, GAxxTC, are recognized, the R loops of the protein become more ordered, forming strong hydrogen-bonding interactions, resulting in a partially bound EcoRV-DNA complex. In the third step, the flexibility of the center base pair is probed, and in the case of the full cognate sequence the DNA bends, the complex strengthens and the protein and DNA interact more closely, allowing cleavage.

A theoretical electronic structure study of this unusual for alpha-oxoketenes [2 + 2] cyclization reaction both in the gas phase (DFT, MP2) and in dichloromethane solution (D FT), provides support for (a) a single-step, transition-state (involving a four-membered cyclic ring) charge-controlled, concerted mechanism and (b) a [4 + 2] cyclization reaction, not observed but studied theoretically in this study. A parallel study of an open-chain alpha,alpha'-dioxoketene dimerization explains the difference in the stability and reactivity observed experimentally between the cyclic and open-chain products.

TI Importance of full Coulomb interactions for understanding the electronic structure of delta-Pu SO PHYSICAL REVIEW B LA English DT Article ID MAGNETIC-PROPERTIES; CORRELATED SYSTEMS; PLUTONIUM; VALENCE; FIELD; SPECTRA AB Understanding the electronic structure of materials containing elements from the end of the periodic table represents a challenge due to a complex interplay of a number of physical phenomena occurring in these systems. In the plutonium metal, a fraction of the valence electrons is at the turning point between joining the conduction cloud, which occupies the whole crystal, and staying bound to a particular atom. This delicate boundary can be probed by photoemission experiments. Here we employ a very accurate computational method-the quantum Monte Carlo simulations-to describe the electronic states in the material achieving previously inaccessible resolution. We show that in order to successfully analyze the experimental photoemission spectra, it is essential to include the complete form of the electron-electron interaction into the Schrodinger equation, otherwise the spectral features near the Fermi level are not correctly reproduced.

TI Experimental and theoretical study of the magnetic and structural properties of Er0.75Tb0.25Al2 SO PHYSICAL REVIEW B LA English DT Article ID LAVES PHASE-COMPOUNDS; ELECTRONIC-STRUCTURE; ALUMINUM; ANISOTROPY; SYSTEMS; FIELD; SPIN AB The Er0.75Tb0.25Al2 alloy has been investigated by x-ray powder diffraction, magnetization, and ac magnetic-susceptibility measurements. The low-field magnetization measured as a function of temperature indicates a ferromagnetic transition at similar to 36 K and another transition with thermal hysteresis at similar to 18 K. The ac magnetic-susceptibility measurements show frequency dependence below the ferromagnetic transition temperature, T-C. Low-temperature x-ray powder-diffraction measurements suggest that although no structural transformation occurs around 18 K, a steplike anomaly in the lattice parameters does exist in the vicinity of the transition. First-principles electronic-structure calculations show anomalous density of states at the Fermi level. The results are comparable with the previously reported Er0.75Dy0.25Al2 alloy, thus supporting an earlier assumption that mixing two rare-earth ions with opposite signs of second-order Steven's factor in RAl2 alloys creates a competition between the magnetoelastic and quadrupolar interactions, giving rise to multiple magnetic ordering phenomena.

The oxygen atoms occupy hcp sites in an ordered structure with (2x1) periodicity. DFT predicts that water is weakly bound to the unmodified surface, 86 meV compared to the similar to 200 meV water-water H bond. Instead, we found that water adsorption causes a shift of half of the oxygen atoms from hcp sites to fcc sites, creating a honeycomb structure where water molecules bind strongly to the exposed Ru atoms. The energy cost of reconstructing the oxygen overlayer, around 230 meV per displaced oxygen atom, is more than compensated by the larger adsorption energy of water on the newly exposed Ru atoms. Water forms hydrogen bonds with the fcc O atoms in a (4x2) superstructure due to alternating orientations of the molecules. Heating to 185 K results in the complete desorption of the water layer, leaving behind the oxygen-honeycomb structure, which is metastable relative to the original (2x1). This stable structure is not recovered until after heating to temperatures close to 260 K.

A full diagonalization of the polarization operator is performed, allowing the extraction of all its poles. It is demonstrated that impurities induce the formation of nanoscale localized plasmonic modes. It is also shown that the chemical potential and impurity strength can be tuned to control target features of the localized modes, making graphene an intrinsic plasmonic material. These predictions can be tested by scanning tunneling microscopy experiments. C1 [Muniz, Rodrigo A.; Haas, Stephan] Univ So Calif, Dept Phys & Astron, Los Angeles, CA 90089 USA.

We provide a characterization of the dynamical properties of this material and their relation to the electronic structure within a combined experimental and theoretical approach. This relies on inelastic neutron scattering to obtain the phonon dispersion while first-principles calculations provide the link between dynamical properties and electronic structure. In contrast to Ni2MnGa, where the softening of the TA(2) phonon branch is related to Fermi-surface nesting, our results reveal that the respective anomalies are absent in Co-Ni-Ga, in the phonon dispersions as well as in the electronic structure.

CA Collaboration, D TI Measurement of the t(t)over-bar cross section using high-multiplicity jet events SO PHYSICAL REVIEW D LA English DT Article ID DETECTOR; PHYSICS AB We present a measurement of the t (t) over bar cross section using high-multiplicity jet events produced in p (p) over bar collisions at root s = 1.96 TeV. These data were recorded at the Fermilab Tevatron Collider with the D0 detector. Events with at least six jets, two of them identified as b jets, were selected from a 1 fb(-1) data set. The measured cross section, assuming a top quark mass of 175 GeV/c(2), is 6.9 +/- 2.0 pb, in agreement with theoretical expectations. C1 [Abazov, V. M.; Alexeev, G. D.; Golovanov, G.; Kharzheev, Y.

This enables double core vacancy Auger electron spectroscopy, an entirely new way to study femtosecond chemical dynamics with Auger electrons that probe the local valence structure of molecules near a specific atomic core. Using 1.1 keV photons for sequential x-ray ionization of impulsively aligned molecular nitrogen, we observed a rich single-site double core vacancy Auger electron spectrum near 413 eV, in good agreement with ab initio calculations, and we measured the corresponding Auger electron angle dependence in the molecular frame.

TI Double Core-Hole Production in N-2: Beating the Auger Clock SO PHYSICAL REVIEW LETTERS LA English DT Article ID CORRELATED MOLECULAR CALCULATIONS; GAUSSIAN-BASIS SETS; SPECTRA; PHOTOIONIZATION; PROPAGATOR; STATES; ATOMS; BORON; NEON AB We investigate the creation of double K-shell holes in N-2 molecules via sequential absorption of two photons on a time scale shorter than the core-hole lifetime by using intense x-ray pulses from the Linac Coherent Light Source free electron laser. The production and decay of these states is characterized by photoelectron spectroscopy and Auger electron spectroscopy. In molecules, two types of double core holes are expected, the first with two core holes on the same N atom, and the second with one core hole on each N atom. We report the first direct observations of the former type of core hole in a molecule, in good agreement with theory, and provide an experimental upper bound for the relative contribution of the latter type.

Both phases have very high bulk moduli of >400 GPa, similar to the most incompressible binary transition-metal (TM) carbides and nitrides found to date. However, in contrast to other incompressible TM carbides and nitrides, Re(3)N is better placed for potential technological applications, as it can be formed at relatively moderate pressures (13-16 GPa) and temperatures (1600-2400 K).

TI Band Structure of SnTe Studied by Photoemission Spectroscopy SO PHYSICAL REVIEW LETTERS LA English DT Article ID IV-VI COMPOUNDS; CRYSTAL-STRUCTURE; APPROXIMATION; TELLURIDE AB We present an angle-resolved photoemission spectroscopy study of the electronic structure of SnTe and compare the experimental results to ab initio band structure calculations as well as a simplified tight-binding model of the p bands. Our study reveals the conjectured complex Fermi surface structure near the L points showing topological changes in the bands from disconnected pockets, to open tubes, and then to cuboids as the binding energy increases, resolving lingering issues about the electronic structure. The chemical potential at the crystal surface is found to be 0.5 eV below the gap, corresponding to a carrier density of p = 1.14 X 10(21) cm(-3) or 7.2 X 10(-2) holes per unit cell. At a temperature below the cubic-rhombohedral structural transition a small shift in spectral energy of the valance band is found, in agreement with model predictions. C1 [Littlewood, P.

TI Transmission of Single HIV-1 Genomes and Dynamics of Early Immune Escape Revealed by Ultra-Deep Sequencing SO PLOS ONE LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-1; IN-VIVO; RHESUS-MONKEYS; INFECTION; EVOLUTION; RESPONSES; VARIANTS; VACCINES; MUTATIONS; PHENOTYPE AB We used ultra-deep sequencing to obtain tens of thousands of HIV-1 sequences from regions targeted by CD8+ T lymphocytes from longitudinal samples from three acutely infected subjects, and modeled viral evolution during the critical first weeks of infection. Previous studies suggested that a single virus established productive infection, but these conclusions were tempered because of limited sampling; now, we have greatly increased our confidence in this observation through modeling the observed earliest sample diversity based on vastly more extensive sampling. Conventional sequencing of HIV-1 from acute/early infection has shown different patterns of escape at different epitopes; we investigated the earliest escapes in exquisite detail. Over 3-6 weeks, ultradeep sequencing revealed that the virus explored an extraordinary array of potential escape routes in the process of evading the earliest CD8 T-lymphocyte responses - using 454 sequencing, we identified over 50 variant forms of each targeted epitope during early immune escape, while only 2-7 variants were detected in the same samples via conventional sequencing. In contrast to the diversity seen within epitopes, non-epitope regions, including the Envelope V3 region, which was sequenced as a control in each subject, displayed very low levels of variation. In early infection, in the regions sequenced, the consensus forms did not have a fitness advantage large enough to trigger reversion to consensus amino acids in the absence of immune pressure. In one subject, a genetic bottleneck was observed, with extensive diversity at the second time point narrowing to two dominant escape forms by the third time point, all within two months of infection. Traces of immune escape were observed in the earliest samples, suggesting that immune pressure is present and effective earlier than previously reported; quantifying the loss rate of the founder virus suggests a direct role for CD8 T-lymphocyte responses in viral containment after peak viremia. Dramatic shifts in the frequencies of epitope variants during the first weeks of infection revealed a complex interplay between viral fitness and immune escape.

Zinc has been shown to play a key role in differentiation of non-pluripotent cell types, but here its role in hESCs is directly examined. By mapping the distribution of metals in hESCs at high resolution by x-ray fluorescence microprobe (XFM) and by analyzing subcellular metal content, we have found evidence that loss of pluripotency is directly correlated with an increase in nuclear zinc. Zinc elevation not only redefines our understanding of the mechanisms that support pluripotency, but also may act as a biomarker and an intervention point for stem cell differentiation.

Sheffield, Stephen A. TI Mass-Spectroscopic Observations of Glycine Subjected to Strong Shock Loading SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID TRANSIENT HIGH-PRESSURE; CHEMISTRY; MOMENTS AB We have made time-of-flight mass-spectroscopic observations of 85/15 wt % water/glycine solutions and of crystalline alpha-glycine subjected to strong shock loading. The shockwaves were produced by placing the materials in contact with detonating solid explosives. In the solution observations, we have done experiments with glycine molecules composed of ordinary isotopes and with molecules labeled with (13)C, (15)N, and D atoms. The primary reason for conducting this research was to examine whether glycine molecules can survive exposure to strong shock loading, e.g., as might occur in the entry of a meteor into the earth's atmosphere. Our results show that glycine molecules can withstand the rigors of shock environments that generate pressure and temperature up to 180 kbar and 3200 K. Glycine in a 85 H(2)O/15 glycine wt % solution (i.e., one molecule of glycine to ca. 24 H(2)O molecules) exists primarily in its zwitterionic form. In both the solution and crystal experiments, we observed zwitterionic dimers, trimers, and, possibly, tetramers, after the materials were shocked. This implies that the solvating water molecules in the solution experiments must reside on the exterior of groups of solvated glycine molecules. We report quantum-chemical calculations, using density functional theory, that predict that two glycine zwitterions are bound together by ca. 15.72 kcal when immersed in an Onsager model of water. Our observations allow us to place lower-bound estimates on the lifetime of glycine zwitterions under our conditions. We have examined our data to determine whether dipeptide formation has occurred and found no evidence that it has. Compressible fluid-mechanical calculations were performed to estimate the pressures, temperatures, and the time scales present in the experiments.

TI Experimental and Theoretical Investigation of the Self-Reaction of Phenyl Radicals SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID POLYCYCLIC AROMATIC-HYDROCARBONS; TRANSITION-STATE THEORY; SHOCK-TUBE; AB-INITIO; THERMAL-DECOMPOSITION; PREDICTIVE THEORY; GASEOUS BENZYNE; LASER-SCHLIEREN; PYROLYSIS; DISSOCIATION AB A combination of experiment and theory is applied to the self-reaction kinetics of phenyl radicals. The dissociation of phenyl iodide is observed with both time-of-flight mass spectrometry, TOF-MS, and laser schlieren, LS, diagnostics coupled to a diaphragmless shock tube for temperatures ranging from 1276 to 1853 K. The LS experiments were performed at pressures of 22 +/- 2, 54 +/- 7, and 122 +/- 6 Torr, and the TOF-MS experiments were performed at pressures in the range 500-700 Torr. These observations are sensitive to both the dissociation of phenyl iodide and to the subsequent self-reaction of the phenyl radicals. The experimental observations indicate that both these reactions are more complicated than previously assumed. The phenyl iodide dissociation yields similar to 6% C6H4 + HI in addition to the major and commonly assumed C6H5 + I channel. The self-reaction of phenyl radicals does not proceed solely by recombination, but also through disproportionation to benzene + o-/m-/p-benzynes, with comparable rate coefficients for both. The various channels in the self-reaction of phenyl radicals are studied with ab initio transition state theory based master equation calculations. These calculations elucidate the complex nature of the C6H5 self-reaction and are consistent with the experimental observations. The theoretical predictions are used as a guide in the development of a model for the phenyl iodide pyrolysis that accurately reproduces the observed laser schlieren profiles over the full range of the observations.

TI Vibronic Analysis of the S-1-S-0 Transition of Phenylacetylene Using Photoelectron Imaging and Spectral Intensities Derived from Electronic Structure Calculations SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID FRANCK-CONDON; AB-INITIO; ETHYNYLBENZENE; NAPHTHALENE AB The vibrational structure of the S-1-S-0 electronic band of phenylacetylene has been recorded by 1 + 1 resonance-enhanced multiphoton ionization, accompanied by slow electron velocity map imaging photoelectron spectroscopy at each resonant vibrational band. Assignments of the S-1 vibrations (up to 2000 cm(-1) above the band origin) are based upon the relative intensities of the vibronic bands calculated by complete second-order vibronic coupling, vibration-rotation (Coriolis and Birss) coupling calculations, and the vibrational structure of the S-1 resonant photoelectron spectra. Although this is an allowed electronic transition, the relative intensities of the a(1) bands are often largely determined by vibronic coupling rather than simple Franck-Condon factors, and second-order coupling is substantial. Nonsymmetric vibrations have intensities obtained through either vibronic or Coriolis coupling, and the calculations have been instrumental in discriminating between alternate possibilities in the assignments. Strong vibronic effects are expected to be present in the spectra of most monosubstituted benzenes, and the calculations presented here show that theoretical treatments based upon electronic structure calculations will generally be useful in the analysis of their spectra.

Using a screening method, the chemical reaction steps that most strongly influence a given kinetic observable are identified. The associated rate coefficients are then improved by high-level quantum chemistry and transition-state-theory calculations, which leads to new values for the coefficients and smaller uncertainty ranges. This updating process is continued as new reactions emerge as the most important steps in the target observable. The screening process employed is a global sensitivity analysis that involves Monte Carlo sampling of the full N-dimensional uncertainty space of rate coefficients, where N is the number of reaction steps. The method is applied to the methanol combustion mechanism of Li et al. (Int. J. Chem. Kinet. 2007, 39, 109.). It was found that the CH(3)OH + HO(2) and CH(3)OH + O(2) reactions were the most important steps in setting the ignition delay time, and the rate coefficients for these reactions were updated. The ignition time is significantly changed for a broad range of high-concentration methanol/oxygen mixtures in the updated mechanism.

TI High-Temperature Measurements and a Theoretical Study of the Reaction of OH with 1,3-Butadiene SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID RADICAL-MOLECULE REACTIONS; TRANSITION-STATE MODEL; REACTION-PATH DYNAMICS; RATE CONSTANTS; INITIATED OXIDATION; GAS-PHASE; MECHANISMS; PYROLYSIS; ALKENES; ALLENE AB The reaction of hydroxyl (OH) radicals with 1,3-butadiene (C(4)H(6)) was studied behind reflected shock waves over the temperature range 1011-1406 K and at pressures near 2.2 atm. OH radicals were produced by shock-heating tert-butyl hydroperoxide, (CH(3))(3)-CO-OH, and were monitored by narrow line width ring dye laser absorption of the well-characterized R(1)(5) line of the OH A-X (0,0) band near 306.7 nm. OH time histories were modeled using a comprehensive 1,3-butadiene oxidation mechanism, and rate constants for the reaction of OH with 1,3-butadiene were extracted by matching modeled and measured OH concentration time histories. Detailed error analyses yielded an uncertainty estimate of +/- 13% at 1200 K for the rate coefficient of the target reaction. The current data extends the temperature range of the only previous high-temperature study for this reaction. The rate coefficient and the branching fractions for the H-abstraction channels of the target reaction were also calculated over the temperature range 250-2500 K using variational transition-state theory based on QCISD(T)/cc-pV infinity Z//B3LYP/6-311++G(d,p) quantum chemistry. The calculations are in good agreement with the experimental results above 1200 K.

Detailed characterization is carried out on those aggregates. The intermediate aggregates show a UV-Vis absorption peak at around 410 nm when dispersed in aqueous solution, whereas the peak is centered on 370 nm when dissolved in an organic solvent such as N-methylpyrrolidone. The electronic band gap decreases when the intermediates aggregate to form a solid, and thus, the absorption peak is red-shifted. Gel permeation chromatography (GPC) shows the aggregates contain a major low molecular weight peak with a long tail. The oligoanilines with low molecular weights consistently show a UV-Vis absorption peak at around 370 nm. Mass spectrometry confirms that the intermediate aggregates contain mainly a component with mass number 363 (M + H(+)), likely a tetramer. UV-Vis, GPC, mass spectrometry, NMR, FTIR, and XRD characterization results are presented and chemical structures for the tetramer are proposed. The major components of the intermediate aggregates are likely highly symmetric phenazine- and dihydrophenazine-containing structures. These particular organic compounds have not been identified before as intermediates. The aggregation and precipitation of the tetramers apparently stabilizes these intermediates. The aggregates are highly crystalline, as evidenced by powder X-ray diffraction. A new reaction mechanism for the formation of these intermediates is proposed.

This approach allows us to reach the time and length scales necessary to study structural and mechanical properties of the bilayer at various temperatures and cholesterol concentrations. The properties studied are the area per lipid, condensation, bilayer thickness, tail order parameters, bending modulus, and area compressibility. Our model quantitatively reproduces most of the experimental effects of cholesterol on these properties and reproduces the main features of the experimental phase and structure diagrams. We also present all-atom simulation results of the system and use these results to further validate the structure of our coarse-grained bilayer. On the basis of the changes in structural properties, we propose a temperature-composition structure diagram, which we compare with the experimental phase and structure diagrams. Attention is paid to the reliability and interpretation of the model and simulation method and of the different experimental techniques. The lateral organization of cholesterol in the bilayer is discussed. C1 [de Meyer, Frederick J-M; Misteli, Yannick; Smit, Berend] Univ Calif Berkeley, Dept Chem Engn, Berkeley, CA 94720 USA.

TI Effects of Annealing Temperature on the Charge-Collection and Light-Harvesting Properties of TiO2 Nanotube-Based Dye-Sensitized Solar Cells SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID BAND-EDGE MOVEMENT; NANOCRYSTALLINE TIO2; ELECTRON-TRANSPORT; THIN-FILMS; PHASE-STABILITY; PARTICLE-SIZE; ARRAYS; RECOMBINATION; OXIDE; TRANSFORMATION AB We report on the influence of annealing temperature (T-a) on the microstructure and dynamics of electron transport and recombination in dye-sensitized solar cells (DSSCs) incorporating oriented titanium oxide nanotube (NT) arrays. The morphology of the NT arrays was characterized by scanning and transmission electron microscopies and Raman and X-ray diffraction spectroscopies. Over the temperature range from 200 to 600 degrees C, the crystallinity, crystal phase, and structural integrity of the NT walls underwent pronounced changes whereas the overall film architecture remained intact. Increasing T-a from 200 to 400 degrees C transformed the as-deposited NT film from the amorphous phase to partially crystalline (300 degrees C) to fully crystalline anatase (400 degrees C). When the as-deposited NTs were detached from the underlying Ti substrate and then annealed, the anatase crystallites comprising the NT walls were stable to at least 600 degrees C in air. When the NTs remained attached to the substrate, thermal oxidation of the Ti metal initiated the growth and propagation of rutile crystallites in the NT walls at relatively low temperatures (ca. 500 degrees C). Once present in the NT walls, the rutile crystallites further catalyzed the anatase-to-rutile transformation, leading to partial degradation of the walls. The percent of ruffle present in the TiO2 NT walls increased from 3% to 32% for samples annealed between 500 and 600 degrees C. Charge transport and recombination properties of dye-sensitized NT films were studied by frequency-resolved modulated photocurrent/photovoltage spectroscopies. Altering the microstructure of the NTs led to significant changes in the electron transport and recombination kinetics in DSSCs. At a fixed photoelectron density, the electron diffusion coefficient and recombination current density are found to change orders of magnitude in the opposite direction over the temperature range. DSSCs containing NT films annealed at 400 degrees C exhibited the fastest transport and slowest recombination kinetics. The various structural changes were also found to affect the light-harvesting, charge-injection, and charge-collection properties of DSSCs, which, in turn, altered the photocurrent density, photovoltage, and solar energy conversion efficiency.

The dominant interfacial feature observed in the 2PPE spectra is a nondispersive unoccupied state whose width and energy (referenced to the Fermi level) decrease with increasing coverage. We assign this feature to a thiophene LUMO-derived state of mixed sulfur and carbon p-pi character. DFT calculations indicate that the experimentally observed decrease in width of this state with increasing coverage is a result of weakening of the thiophene Au(11 I) interaction. Increasing the molecular density forces the thiophene plane to tilt away from the surface, rotating the molecular orbitals away from an orientation more favorable for S-Au and pi-Au hybridization. We attribute the similar to 0.2 eV shift of the LUMO toward the Fermi level to stabilization of the transient anion due to the increasing effect of charge-induced polarization of the neighboring thiophene molecules with increasing coverage.

TI Photocatalytic Water Oxidation at the GaN (10(1)over-bar0)-Water Interface SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID MOLECULAR-ORBITAL METHODS; DENSITY-FUNCTIONAL THEORY; GAUSSIAN-BASIS SETS; 3RD-ROW ATOMS; ORGANIC-MOLECULES; FREE-ENERGY; ROW ATOMS; POTENTIALS; SOLVATION; EXTENSION AB Domen has observed that the GaN/ZnO semiconductor alloy serves, in the presence of a sacrificial electron scavenger, as a photocatalyst for solar water oxidation, producing H+ and O-2 at the aqueous/semiconductor interface. With a suitable cocatalyst, the same solar photoexcitation process also generates H-2 from H+. The active sites, mechanisms, and reaction intermediates are not known. This paper describes atomistic modeling and proposes a sequence of intermediate steps for the water oxidation process at a pure GaN/water interface. Pure GaN is known to be photocatalytically active but only in the UV region, because the semiconductor band gap is 3.4 eV, outside the visible region of the spectrum. However, it serves as an appropriate model system in the absence of more detailed information. A fiat (10 (1) over bar0) nonpolar surface is chosen to model an active site. Ab initio molecular dynamics simulations examine the fully solvated aqueous interface at ambient temperature. An appropriate cluster model, that includes a polarizable continuum in addition to explicit solvent water molecules, is cut out from snapshots of these AIMD simulations for additional DFT-based calculations of the water oxidation mechanism. The reaction intermediates follow a sequence of four proton-coupled electron transfers. Four UV photons are consumed to generate the four photoholes which drive the oxidation, producing 4H(+) + O-2 from 2H(2)O. Calculated standard free energies show that the photogenerated holes in GaN have sufficient energy to drive the overall water oxidation reaction. Implications for the operation of GaN/ZnO alloy photocatalysts, which absorb in the visible wavelength range, are presented. The calculated potentials show a remarkable parallelism to the known potentials for the sequential one-electron oxidation of water in homogeneous aqueous solution, suggesting that the proposed sequence may apply more generally than for the specific GaN (10 (1) over bar0) surface catalyst.

Frequently, electrochemically controlled redox cycling results in the dramatic alteration in polymer film properties, typically accompanied by loss of redox activity, exemplified in this case by negligible currents associated with repeated exposure to GGG. Notably, we have discovered that preconditioning of PVF films with suitable ionic liquids (ILs) such as the N-alkyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)imides allows the electroactive film to relax to a state compatible with reversible GGG(-) doping/undoping. Our studies substantiate that both the cation and the anion of the IL must be considered as both play important roles in appropriately conditioning the PVF polymer films. Indeed, ILs with structures and properties highly divergent from the target GGG(-) failed to properly condition PVF to a compatible state.

UV second harmonic generation resonant with the bromide charge-transfer-to-solvent band and a Langmuir adsorption model are used to determine the affinity of bromide for both the air/water and dodecanol/water interfaces. The Gibbs free energy of adsorption for the former is determined to be -1.4 kJ/mol with a lower 90% confidence limit of -4.1 kJ/mol. For the dodecanol/water interface the data are best fit with a Gibbs free energy of +8 kJ/mol with an estimated lower limit of -4 kJ/mol.

The NTO overlayer was found to block oxygen diffusion into AZO during the air-annealing process for the fabrication process of the DSSCs, thereby exhibiting good thermal stability in electrical conductivity of the multilayer TCO. Moreover, the NTO overlayer suppressed the formation of Zn2+-dye aggregates at the surface of the AZO. The DSSC employing this multilayer TCO showed a photon to electron conversion efficiency of 3.8% compared to 1.9% for the cell employing the AZO single layer. The optical transmittance and charge transport properties that were measured using electrochemical impedance spectroscopy demonstrate that NTO/AZO is a promising TCO for large scale DSSCs.

TI Decomposition Pathway of Ammonia Borane on the Surface of Nano-BN SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID CHEMICAL HYDROGEN STORAGE; METAL-ORGANIC FRAMEWORKS; HEXAGONAL BORON-NITRIDE; THERMAL-DECOMPOSITION; CATALYZED DEHYDROGENATION; CARBON NANOSTRUCTURES; GENERATION SYSTEM; ROOM-TEMPERATURE; ADSORPTION; RELEASE AB Ammonia borane (AB) is under significant investigation as a possible hydrogen storage material. While chemical additives have been shown to lower the temperature for hydrogen release from ammonia borane, many provide additional complications in the regeneration cycle. Mechanically alloyed hexagonal boron nitride (nano-BN) has been shown to facilitate the release of hydrogen from AB at lower temperature, with minimal induction time and less exothermicity, and inert nano-BN may be easily removed during any regeneration of the spent AB. The samples were prepared by mechanically alloying AB with nano-BN. Raman spectroscopy indicates that the AB/nano-BN samples are physical mixtures of AB and h-BN. The release of hydrogen from AB/nano-BN mixtures as well as the decomposition products was characterized by (11)B magic angle spinning (MAS) solid state NMR spectroscopy, TGA/DSC/MS with (15)N-labeled AB, and solution (11)B NMR spectroscopy. The (11)B MAS solid state NMR spectrum shows that diammoniate of diborane (DADB) is present in the mechanically alloyed mixture, which drastically shortens the induction period for hydrogen release from AB. Analysis of the TGA/DSC/MS spectra with (15)N-labeled AB shows that all the borazine (BZ) produced in the reaction comes from AB and that increasing nano-BN surface area results in increased amounts of BZ. However, under high temperature, 150 degrees C, isothermal conditions, the amount of BZ released significantly decreases. High resolution transmission electron microscopy (HRTEM), selected area diffraction (SAD), and electron energy loss spectroscopy (EELS) of the initial and final nano-BN additive provide evidence for crystallinity loss but not significant chemical changes. The higher concentration of BZ observed for low-temperature dehydrogenation of AB/nano-BN mixtures versus neat AB is attributed to a surface interaction that favors the formation of precursors which ultimately result in BZ. This pathway can be avoided through isothermal heating at temperatures lower than 150 degrees C.

TI A strong ferroelectric ferromagnet created by means of spin-lattice coupling SO NATURE LA English DT Article ID THIN-FILMS; MAGNETIC-PROPERTIES; ROOM-TEMPERATURE; ELECTRIC-FIELD; OXIDE; POLARIZATION; SYSTEMS; SRTIO3 AB Ferroelectric ferromagnets are exceedingly rare, fundamentally interesting multiferroic materials that could give rise to new technologies in which the low power and high speed of field-effect electronics are combined with the permanence and routability of voltage-controlled ferromagnetism(1,2). Furthermore, the properties of the few compounds that simultaneously exhibit these phenomena(1-5) are insignificant in comparison with those of useful ferroelectrics or ferromagnets: their spontaneous polarizations or magnetizations are smaller by a factor of 1,000 or more. The same holds for magnetic-or electric-field-induced multiferroics(6-8). Owing to the weak properties of single-phase multiferroics, composite and multilayer approaches involving strain-coupled piezoelectric and magnetostrictive components are the closest to application today(1,2). Recently, however, a new route to ferroelectric ferromagnets was proposed(9) by which magnetically ordered insulators that are neither ferroelectric nor ferromagnetic are transformed into ferroelectric ferromagnets using a single control parameter, strain. The system targeted, EuTiO(3), was predicted to exhibit strong ferromagnetism (spontaneous magnetization, similar to 7 Bohr magnetons per Eu) and strong ferroelectricity (spontaneous polarization, similar to 10 mu C cm(-2)) simultaneously under large biaxial compressive strain(9). These values are orders of magnitude higher than those of any known ferroelectric ferromagnet and rival the best materials that are solely ferroelectric or ferromagnetic. Hindered by the absence of an appropriate substrate to provide the desired compression we turned to tensile strain. Here we show both experimentally and theoretically the emergence of a multiferroic state under biaxial tension with the unexpected benefit that even lower strains are required, thereby allowing thicker high-quality crystalline films. This realization of a strong ferromagnetic ferroelectric points the way to high-temperature manifestations of this spin-lattice coupling mechanism(10). Our work demonstrates that a single experimental parameter, strain, simultaneously controls multiple order parameters and is a viable alternative tuning parameter to composition(11) for creating multiferroics.

TI Effective thermal boundary resistance from thermal decoupling of magnons and phonons in SrRuO3 thin films SO PHYSICAL REVIEW B LA English DT Article ID TRANSPORT; DYNAMICS; INTERFACES; ANISOTROPY; ELECTRON; TIME AB We use the time-resolved magneto-optical Kerr effect to measure the local temperature and heat-flow dynamics in ferromagnetic SrRuO3 thin films. After heating by a pump pulse, the film temperature decays exponentially, indicating that the heat flow out of the film is limited by the film/substrate interface. We show that this behavior is consistent with an effective boundary resistance resulting from disequilibrium between the spin and phonon temperatures in the film. C1 [Langner, M. C.; Kantner, C. L.

CA CDF Collaboration TI Search for the Production of Scalar Bottom Quarks in p(p)over-bar Collisions at root s=1.96 TeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID HADRON COLLIDERS; PHYSICS; MODEL AB We report on a search for direct scalar bottom quark (sbottom) pair production in p (p) over bar collisions at root s = 1.96 TeV, in events with large missing transverse energy and two jets of hadrons in the final state, where at least one of the jets is required to be identified as originating from a b quark. The study uses a collider detector at Fermilab Run II data sample corresponding to 2.65 fb(-1) of integrated luminosity. The data are in agreement with the standard model. In an R-parity conserving minimal supersymmetric scenario, and assuming that the sbottom decays exclusively into a bottom quark and a neutralino, 95% confidence-level upper limits on the sbottom pair production cross section of 0.1 pb are obtained. For neutralino masses below 70 GeV/c(2), sbottom masses up to 230 GeV/c(2) are excluded at 95% confidence level.

TI Effective Low-Energy Model for f-Electron Delocalization SO PHYSICAL REVIEW LETTERS LA English DT Article ID HIGH-TEMPERATURE SUPERCONDUCTORS; DENSITY-MATRIX RENORMALIZATION; ANTIFERROMAGNETISM; MATTER; CEIN3 AB We consider a periodic Anderson model (PAM) with a momentum-dependent interband hybridization that is strongly suppressed near the Fermi level. Under these conditions, we reduce the PAM to an effective low-energy Hamiltonian, H(eff), by expanding in the small parameter V(0)/t ( V(0) is the maximum interband hybridization amplitude and t is the hopping integral of the broadband). The resulting model consists of a t - J f-band coupled via the Kondo exchange to the electrons in the broadband. H(eff) allows for studying the f-electron delocalization transition. The result is a doping-induced Mott transition for the f-electron delocalization, which we demonstrate by density-matrix renormalization group calculations. C1 [Al-Hassanieh, K.

TI Suppression of Octahedral Tilts and Associated Changes in Electronic Properties at Epitaxial Oxide Heterostructure Interfaces SO PHYSICAL REVIEW LETTERS LA English DT Article ID FERROELECTRIC-FILMS; SCALE AB Epitaxial oxide interfaces with broken translational symmetry have emerged as a central paradigm behind the novel behaviors of oxide superlattices. Here, we use scanning transmission electron microscopy to demonstrate a direct, quantitative unit-cell-by-unit-cell mapping of lattice parameters and oxygen octahedral rotations across the BiFeO(3)-La(0.7)Sr(0.3)MnO(3) interface to elucidate how the change of crystal symmetry is accommodated. Combined with low-loss electron energy loss spectroscopy imaging, we demonstrate a mesoscopic antiferrodistortive phase transition near the interface in BiFeO(3) and elucidate associated changes in electronic properties in a thin layer directly adjacent to the interface.

CA BABAR Collaboration TI Measurement of D-0-(D)over-bar(0) Mixing Parameters Using D-0 -> K-S(0)pi(+) pi(-) and D-0 -> (KSK+K-)-K-0 Decays SO PHYSICAL REVIEW LETTERS LA English DT Article AB We report a direct measurement of D-0-(D) over bar (0) mixing parameters through a time-dependent amplitude analysis of the Dalitz plots of D-0 -> K-S(0)pi(+)pi(-) and, for the first time, D-0 -> (KSK+K-)-K-0 decays. The low-momentum pion pi(+)(s) in the decay D*(+) -> D-0 pi(+)(s) identifies the flavor of the neutral D meson at its production. Using 468.5 fb(-1) of e(+)e(-) colliding-beam data recorded near root s = 10.6 by the BABAR detector at the PEP-II asymmetric-energy collider at SLAC, we measure the mixing parameters x = [1.6 + 2.3(stat) +/- 1.2(syst) +/- 0.8(model)] X 10(-3), and y = [5.7 +/- 2.0(stat) +/- 1.3(syst) +/- 0.7(model)] X 10(-3). These results provide the best measurement to date of x and y. The knowledge of the value of x, in particular, is crucial for understanding the origin of mixing. C1 [Sanchez, P. del Amo; Lees, J.

Orbital occupation numbers computed by perfect pairing (PP), complete active space SCF (CASSCF), and restricted active space double spin-flip (RAS-2SF) reveal the presence of less than one unpaired electron in the planar molecules. Thus, the surprising stability of the " para tetraradical" can be rationalized by its moderate extent of radical character. Estimation of the delocalization energy, low-lying excited states, and short and long-range magnetic coupling constants all indicate a rather weak interaction to occur between two singlet PBPB units. Communication between two triplet units was found to be negligible. Comparison between para and meta isomers confirms a distinctly larger communication via the Jr framework for the former. However, this communication, which was recently proposed to be the main factor for the different behavior of meta and para isomers regarding their preferred geometries, was found to account for only one-third of their energy difference. The study shows the important contribution of steric and/or electronic effects of the bulky 'Pr and 1I3u substituents on P and B.

Our analysis further reveals that the resonance peak near 7 meV only occurs for the planar response. This challenges the common perception that the spin resonance in the pnictides is an isotropic triplet excited state of the singlet Cooper pairs, as our results imply that only the S-001= +/- 1 components of the triplet are involved.

Analyses show that it arises from radiative recombination of a broad distribution of nonequilibrium electrons and holes, generated by rapid scattering between photoexcited carriers within tens of femtoseconds after the optical excitation. Its highly unusual characteristics come from the unique electronic and structural properties of graphene. C1 [Liu, Wei-Tao; Shen, Y.

TI Doping dependence of spin dynamics in electron-doped Ba(Fe1-xCox)(2)As-2 SO PHYSICAL REVIEW B LA English DT Article ID LOW-TEMPERATURES; SUPERCONDUCTIVITY AB The spin dynamics in single crystal, electron-doped Ba(Fe1-xCox)(2)As-2 has been investigated by inelastic neutron scattering over the full range from undoped to the overdoped regime. We observe damped magnetic fluctuations in the normal state of the optimally doped compound (x= 0.06) that share a remarkable similarity with those in the paramagnetic state of the parent compound (x= 0). In the overdoped superconducting compound (x=0.14), magnetic excitations show a gaplike behavior, possibly related to a topological change in the hole Fermi surface (Lifshitz transition) while the imaginary part of the spin susceptibility chi '' prominently resembles that of the overdoped cuprates. For the heavily overdoped, nonsuperconducting compound (x=0.24) the magnetic scattering disappears, which could be attributed to the absence of a hole Fermi-surface pocket observed by photoemission.

TI Tuning low-temperature physical properties of CeNiGe3 by magnetic field SO PHYSICAL REVIEW B LA English DT Article ID SINGLE-CRYSTALS; GADOLINIUM COMPOUNDS; PHASE-TRANSITIONS; HEAT; TRANSPORT; GROWTH; POINT AB We have studied the thermal, magnetic, and electrical properties of the ternary intermetallic system CeNiGe3 by means of specific heat, magnetization, and resistivity measurements. The specific heat data, together with the anisotropic magnetic susceptibility, was analyzed on the basis of the point charge model of crystalline electric field. The J=5/2 multiplet of the Ce3+ is split by the crystalline electric field into three Kramers doublets, where the second and third doublets are separated from the first (ground state) doublet by Delta(1) similar to 100 K and Delta(2) similar to 170 K, respectively. In zero field CeNiGe3 exhibits an antiferromangeic order below T-N = 5.0 K. For H parallel to a two metamagnetic transitions are clearly evidenced between 2-4 K from the magnetization isotherm and extended down to 0.4 K from the magnetoresistance measurements. For H parallel to a, T-N shifts to lower temperature as magnetic field increases, and ultimately disappears at H-c similar to 32.5 kOe. For H > H-c, the electrical resistivity shows the quadratic temperature dependence (Delta p=AT(2)). For H >> H-c, an unconventional T-n dependence of Delta p with n > 2 emerges, the exponent n becomes larger as magnetic field increases. Although the antiferromagnetic phase transition temperature in CeNiGe3 can be continuously suppressed to zero, it provides an example of field tuning that does not match current simple models of quantum criticality.

TI New perspectives on the quark condensate SO PHYSICAL REVIEW C LA English DT Article ID CHIRAL-SYMMETRY-BREAKING; HADRON DECAY PROCESSES; QUANTUM CHROMODYNAMICS; CONFINING THEORIES; QCD; CONSTANT; PHYSICS; MODEL; MASS AB We show that the chiral-limit vacuum quark condensate is qualitatively equivalent to the pseudoscalar meson leptonic decay constant in the sense that they are both obtained as the chiral-limit value of well-defined gauge-invariant hadron-to-vacuum transition amplitudes that possess a spectral representation in terms of the current-quark mass. Thus, whereas it might sometimes be convenient to imagine otherwise, neither is essentially a constant mass-scale that fills all spacetime. This means, in particular, that the quark condensate can be understood as a property of hadrons themselves, which is expressed, for example, in their Bethe-Salpeter or light-front wave functions.

TI Half-lives and branchings for beta-delayed neutron emission for neutron-rich Co-Cu isotopes in the r-process SO PHYSICAL REVIEW C LA English DT Article ID ATOMIC MASS EVALUATION; BURST ACCRETION DISKS; SUPERNOVA EXPLOSIONS; NUCLEAR-STRUCTURE; PROCESS NUCLEOSYNTHESIS; STRENGTH FUNCTIONS; PROCESS ABUNDANCES; DECAY PROPERTIES; CROSS-SECTIONS; EXOTIC NUCLEI AB The beta decays of very neutron-rich nuclides in the Co-Zn region were studied experimentally at the National Superconducting Cyclotron Laboratory using the NSCL beta-counting station in conjunction with the neutron detector NERO. We measured the branchings for beta-delayed neutron emission (P(n) values) for (74)Co (18 +/- 15%) and (75-77)Ni (10 +/- 2.8%, 14 +/- 3.6%, and 30 +/- 24%, respectively) for the first time, and remeasured the P(n) values of (77-79)Cu, (79,81)Zn, and (82)Ga. For (77-79)Cu and for (81)Zn we obtain significantly larger P(n) values compared to previous work. While the new half-lives for the Ni isotopes from this experiment had been reported before, we present here in addition the first half-life measurements of (75)Co (30 +/- 11 ms) and (80)Cu (170(-50)(+110) ms). Our results are compared with theoretical predictions, and their impact on various types of models for the astrophysical rapid neutron-capture process (r-process) is explored. We find that with our new data, the classical r-process model is better able to reproduce the A = 78-80 abundance pattern inferred from the solar abundances. The new data also influence r-process models based on the neutrino-driven high-entropy winds in core collapse supernovae. C1 [Hosmer, P.; Schatz, H.; Clement, R. R. C.; Estrade, A.; Liddick, S.

TI Antiferromagnetically Spin Polarized Oxygen Observed in Magnetoelectric TbMn2O5 SO PHYSICAL REVIEW LETTERS LA English DT Article ID NEUTRON-DIFFRACTION; SCATTERING AB We report the direct measurement of antiferromagnetic spin polarization at the oxygen sites in the multiferroic TbMn2O5, through resonant soft x-ray magnetic scattering. This supports recent theoretical models suggesting that the oxygen spin polarization is key to the magnetoelectric coupling mechanism. The spin polarization is observed through a resonantly enhanced diffraction signal at the oxygen K edge at the commensurate antiferromagnetic wave vector. Using the FDMNES code we have accurately reproduced the experimental data. We have established that the resonance arises through the spin polarization on the oxygen sites hybridized with the square based pyramid Mn3+ ions. Furthermore we have discovered that the position of the Mn3+ ion directly influences the oxygen spin polarization. C1 [Beale, T. A. W.; Johnson, R. D.; Bland, S. R.; Hatton, P.

Distinct dynamical pathways of crystal formation can be selected by tuning the strengths of these interactions. When the nonspecific interaction is strong, liquidlike clustering can precede crystallization; when it is weak, growth can proceed via ordered nuclei. Crystal yields are in certain parameter regimes enhanced by the nonspecific interaction, even though it promotes association without local crystalline order. Our results suggest that equipping nanoscale components with weak nonspecific interactions (such as depletion attractions) can alter both their dynamical pathway of assembly and optimize the yield of the resulting material.

TI Magnetic field at geosynchronous orbit during high-speed stream-driven storms: Connections to the solar wind, the plasma sheet, and the outer electron radiation belt SO JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS LA English DT Article ID COROTATING INTERACTION REGIONS; HELIOSPHERIC CURRENT SHEET; PITCH-ANGLE DISTRIBUTIONS; CORONAL MASS EJECTIONS; VAN-ALLEN RADIATION; GEOMAGNETIC STORMS; RING CURRENT; POLAR-CAP; RELATIVISTIC ELECTRONS; DYNAMIC PRESSURE AB Superposed-epoch analysis is performed on magnetic field measurements from five GOES spacecraft in geosynchronous orbit during 63 high-speed stream-driven storms in 1995-2005. The field strength and the field stretching angle are examined as functions of time and local time, and these quantities are compared with the properties of the solar wind, the plasma sheet, and the outer electron radiation belt. Compression of the dayside magnetosphere coincides with an increased solar wind ram pressure commencing before the arrival of the corotating interaction region (CIR). Stretching of the nightside magnetosphere occurs in two phases: a strong-stretching phase early in the storm followed by a modest-stretching phase lasting for days. The strong-stretching phase coincides with the occurrence of the superdense plasma sheet, implying that ion pressure causes the strong stretching. This nightside strong-stretching perturbation corresponds to a similar to 25% contribution to Dst*. The relativistic electron flux at geosynchronous orbit has a dropout recovery temporal profile that matches the strong-stretching temporal profile; however, the number density dropout and recovery of the electron radiation belt has a profile that leads the stretching profile. A comparison of geosynchronous field strengths and magnetopause field strengths indicates that magnetopause shadowing plays a role in the radiation belt dropout. Temporal fluctuations of the geosynchronous magnetic field are examined via 1 min changes of the GOES magnetic field vectors. Fluctuation amplitudes increase at all local times at storm onset and then slowly decay during the storms. The amplitude is linearly related to the Kp, PCI, and MBI indices, except during the strong-stretching phase of the storms. C1 [Borovsky, Joseph E.] Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

These nanoparticles could provide the ability to control thin film morphology independently of optical and electronic properties. Using poly(3-hexylthiophene), we demonstrate surfactant-free synthesis and characterization of size-controlled, semicrystalline polymer nanoparticles. Our method produces discrete nanoparticles that can be deposited from solution into thin films. By controlling the molecular weight, polydispersity, and regioregularity of the polymer as well as varying its initial solution concentration, we tune both the size and crystallinity of the resulting nanoparticles. Organic field effect transistors (OFETs) using,nanoparticles made from this method produce good semiconducting devices with hole mobilities on the order of 10(-3) cm(2)/(V s). This approach to forming polymer nanoparticles is attractive for the introduction of solution-processablc, well-characterized nanoscale crystalline domains of a variety of conjugated polymers and should be useful for the fabrication and optimization of organic electronic devices.

TI Structure and physical properties of the noncentrosymmetric superconductor Mo3Al2C SO PHYSICAL REVIEW B LA English DT Article ID INVERSION SYMMETRY; SPIN; Y2C3 AB We have synthesized polycrystalline samples of the noncentrosymmetric superconductor Mo3Al2C by arc and RF melting, measured its transport, magnetic and thermodynamic properties, and computed its band structure. Experimental results indicate a bulk superconducting transition at T-c similar to 9.2 K while the density of states at the Fermi surface is found to be dominated by Mo d orbitals. Using the measured values for the lower critical field H-c1, upper critical field H-c2, and the specific heat C, we estimated the thermodynamic critical field H-c(0), coherence length xi(0), penetration depth lambda(0), and the Ginzburg-Landau parameter kappa(0). The specific-heat jump at T-c, Delta C/gamma T-c=2.14, suggests that Mo3Al2C is moderately to strongly coupled, consistent with the fast opening of the gap, as evidenced by the rapid release of entropy below T-c from our electronic specific-heat measurements. Above 2 K the electronic specific heat exhibits the power-law behavior, suggesting that synthesis of single crystals and measurements at lower temperature are needed to establish whether the gap is anisotropic. The estimated value of the upper critical field H-c2(0) is close to the calculated Pauli limit, therefore further studies are needed to determine whether the absence of an inversion center results in a significant admixture of the triplet component of the order parameter.

Oscillatory behaviors attributed to the Aharonov-Bohm effect are simultaneously observed for the emission energy and intensity of excitons subject to an increasing magnetic field. When the magnetic flux penetrates through the ringlike trajectory of an electron moving around each quantum dot, the ground state of an exciton experiences a change in its angular momentum. Our results provide the experimental evidence for the phase coherence of localized electron wave functions in group-IV Ge/Si self-assembled quantum structures.

TI Implications of simultaneous requirements for low-noise exchange gates in double quantum dots SO PHYSICAL REVIEW B LA English DT Article ID SPINS AB Achieving low-error, exchange-interaction operations in quantum dots for quantum computing imposes simultaneous requirements on the exchange energy's dependence on applied voltages. A double quantum dot qubit, approximated with a quadratic potential, is solved using a full configuration interaction method. This method is more accurate than Heitler-London and Hund-Mulliken approaches and captures new and significant qualitative behavior. We show that multiple regimes can be found in which the exchange energy's dependence on the bias voltage between the dots is compatible with current quantum error correction codes and state-of-the-art electronics. Identifying such regimes may prove valuable for the construction and operation of quantum gates that are robust to charge fluctuations, particularly in the case of dynamically corrected gates.

SO PHYSICAL REVIEW D LA English DT Article ID POWER-SPECTRUM; COSMOLOGICAL PARAMETERS; ACOUSTIC-OSCILLATIONS; REDSHIFT SURVEYS; WEAK; MATTER; MODEL; TOMOGRAPHY; COLLAPSE; BARYONS AB One of the most pressing issues in cosmology is whether general relativity (GR) plus a dark sector is the underlying physical theory or whether a modified gravity model is needed. Upcoming dark energy experiments designed to probe dark energy with multiple methods can address this question by comparing the results of the different methods in constraining dark energy parameters. Disagreement would signal the breakdown of the assumed model (GR plus dark energy). We study the power of this consistency test by projecting constraints in the w(0)-w(a) plane from the four different techniques of the Dark Energy Survey in the event that the underlying true model is modified gravity. We find that the standard technique of looking for overlap has some shortcomings, and we propose an alternative, more powerful Multidimensional Consistency Test. We introduce the methodology for projecting whether a given experiment will be able to use this test to distinguish a modified gravity model from GR.

TI Shock Compression of a Fifth Period Element: Liquid Xenon to 840 GPa SO PHYSICAL REVIEW LETTERS LA English DT Article ID AUGMENTED-WAVE METHOD; DENSITY; TRANSITION; SURFACE; GAS AB Current equation of state (EOS) models for xenon show substantial differences in the Hugoniot above 100 GPa, prompting the need for an improved understanding of xenon's behavior at extreme conditions. We performed shock compression experiments on liquid xenon to determine the Hugoniot up to 840 GPa, using these results to validate density functional theory (DFT) simulations. Despite the nearly fivefold compression, we find that the limiting Thomas-Fermi theory, exact in the high density limit, does not accurately describe the system. Combining the experimental data and DFT calculations, we developed a free-energy-based, multiphase EOS capable of describing xenon over a wide range of pressures and temperatures.

In this article, we report an approach for synthesizing an ideal class of colloidal Ag nanoparticles with highly uniform morphologies and narrow size distributions. Optical measurements and theoretical analyses for particle diameters in the d approximate to 2-20 nm range are presented. The SPR absorption band exhibits an exceptional behavior: As size decreases from d approximate to 20 nm it blue-shifts but then turns over near d approximate to 12 nm and strongly red-shifts. A multilayer Mie theory model agrees well with the observations, indicating that lowered electron conductivity in the outermost atomic layer, due to chemical interactions, is the cause of the red-shift. We corroborate this picture by experimentally demonstrating precise chemical control of the SPR peak positions via ligand exchange.

TI Targeted metagenomics and ecology of globally important uncultured eukaryotic phytoplankton SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE comparative genomics; primary production; prymnesiophytes; marine photosynthesis; haptophytes ID EQUATORIAL PACIFIC; COMMUNITY STRUCTURE; PLASTID GENOMES; SARGASSO SEA; OCEAN; PICOPHYTOPLANKTON; DIVERSITY; PIGMENT; EVOLUTION; PROCHLOROCOCCUS AB Among eukaryotes, four major phytoplankton lineages are responsible for marine photosynthesis; prymnesiophytes, alveolates, stramenopiles, and prasinophytes. Contributions by individual taxa, however, are not well known, and genomes have been analyzed from only the latter two lineages. Tiny "picoplanktonic" members of the prymnesiophyte lineage have long been inferred to be ecologically important but remain poorly characterized. Here, we examine pico-prymnesiophyte evolutionary history and ecology using cultivation-independent methods. 18S rRNA gene analysis showed pico-prymnesiophytes belonged to broadly distributed uncultivated taxa. Therefore, we used targeted metagenomics to analyze uncultured pico-prymnesiophytes sorted by flow cytometry from subtropical North Atlantic waters. The data reveal a composite nuclear-encoded gene repertoire with strong green-lineage affiliations, which contrasts with the evolutionary history indicated by the plastid genome. Measured pico-prymnesiophyte growth rates were rapid in this region, resulting in primary production contributions similar to the cyanobacterium Prochlorococcus. On average, pico-prymnesiophytes formed 25% of global picophytoplankton biomass, with differing contributions in five biogeographical provinces spanning tropical to subpolar systems. Elements likely contributing to success include high gene density and genes potentially involved in defense and nutrient uptake. Our findings have implications reaching beyond pico-prymnesiophytes, to the prasinophytes and stramenopiles. For example, prevalence of putative Ni-containing superoxide dismutases (SODs), instead of Fe-containing SODs, seems to be a common adaptation among eukaryotic phytoplankton for reducing Fe quotas in low-Fe modern oceans. Moreover, highly mosaic gene repertoires, although compositionally distinct for each major eukaryotic lineage, now seem to be an underlying facet of successful marine phytoplankton.

Like the termite hindgut and bovine rumen, key enzymes and modular structures characteristic of the "free enzyme" and "cellulosome" paradigms of cellulose solubilization remain either poorly represented or elusive to capture by shotgun sequencing methods. Instead, multigene polysaccharide utilization loci-like systems coupled with genes encoding beta-1,4-endoglucanases and beta-1,4-endoxylanases-which have not been previously encountered in metagenomic datasets-were identified, as were a diverse set of glycoside hydrolases targeting noncellulosic polysaccharides. Furthermore, both rrs gene and other phylogenetic analyses confirmed that unique clades of the Lachnospiraceae, Bacteroidales, and Gammaproteobacteria are predominant in the Tammar foregut microbiome. Nucleotide composition-based sequence binning facilitated the assemblage of more than two megabase pairs of genomic sequence for one of the novel Lachnospiraceae clades (WG-2). These analyses show that WG-2 possesses numerous glycoside hydrolases targeting noncellulosic polysaccharides. These collective data demonstrate that Australian macropods not only harbor unique bacterial lineages underpinning plant biomass conversion, but their repertoire of glycoside hydrolases is distinct from those of the microbiomes of higher termites and the bovine rumen.

In addition to the expected SPC-induced phase transition from amorphous to polycrystalline silicon, our XES data indicates a pronounced chemical interaction at the buried Si/ZnO interface. In particular, we find an SPC-enhanced formation of Si-O bonds and the accumulation of Zn in close proximity to the interface. For an assumed closed and homogeneous SiO(2) interlayer, an effective thickness of (5 +/- 2) nm after SPC could be estimated. (C) 2010 American Institute of Physics.

The superconductor metamaterial is found to show a remarkable change in the transmission spectra at the fundamental inductive-capacitive resonance as the temperature dips below the critical transition temperature. This resonance switching effect is normally absent in traditional metamaterials made up of regular metals. The temperature-dependent resonance behavior of the superconducting metamaterial would lead to development of low loss terahertz switches at cryogenic temperatures.

TI Indium induced step transformation during InGaN growth on GaN SO APPLIED PHYSICS LETTERS LA English DT Article DE gallium compounds; III-V semiconductors; indium compounds; MOCVD; semiconductor growth; semiconductor quantum wells ID LIGHT-EMITTING-DIODES; EFFICIENCY AB The surface-step evolution of InGaN quantum-wells (QWs) was studied on GaN (0001). While the GaN template is dominated by single-monolayer steps the frequency of multiple-layer steps increases significantly when InGaN/GaN single- or multiple-QWs are grown. It is proposed that the InGaN multiple-layer step structure arises to partially accommodate the in-plane film strain which is insufficient to trigger bulk InGaN relaxation. This intrinsic multiple-layer step restructuring, when coupled with the strong piezoelectric fields present in the wurtzite group III-nitrides, could explain the enhanced carrier localization in InGaN QWs.

We find direct experimental evidence that, in the initial deposition steps, the sulfur atoms on the Cu(In,Ga)Se-2 surface exist in at least two distinct chemical environments, namely CdS and a compound involving Ga and In.

Using a four-probe setup, single-layer nanoribbon (SLR) and bilayer nanoribbon (BLR) show low-frequency noise levels lower than (comparable to) the SLRs (BLRs) achieved by hydrogen-silsesquioxane based methods. Submicron channel SLR and BLR both show conductance quantization at 77 K, which suggests that quasi-one-dimensional quantum transport can be achieved. The conductance plateaus in BLR are less pronounced than those in SLR. (C) 2010 American Institute of Physics.

In the case of the key grassland species Lolium spp., numerous mapping populations have been developed and characterised for various traits. Although some genetic linkage maps of these populations have been aligned with each other using publicly available DNA markers, the number of common markers among genetic maps is still low, limiting the ability to compare candidate gene and QTL locations across germplasm. Results: A set of 204 expressed sequence tag (EST)-derived simple sequence repeat (SSR) markers has been assigned to map positions using eight different ryegrass mapping populations. Marker properties of a subset of 64 EST-SSRs were assessed in six to eight individuals of each mapping population and revealed 83% of the markers to be polymorphic in at least one population and an average number of alleles of 4.88. EST-SSR markers polymorphic in multiple populations served as anchor markers and allowed the construction of the first comprehensive consensus map for ryegrass. The integrated map was complemented with 97 SSRs from previously published linkage maps and finally contained 284 EST-derived and genomic SSR markers. The total map length was 742 centiMorgan (cM), ranging for individual chromosomes from 70 cM of linkage group (LG) 6 to 171 cM of LG 2. Conclusions: The consensus linkage map for ryegrass based on eight mapping populations and constructed using a large set of publicly available Lolium EST-SSRs mapped for the first time together with previously mapped SSR markers will allow for consolidating existing mapping and QTL information in ryegrass. Map and markers presented here will prove to be an asset in the development for both molecular breeding of ryegrass as well as comparative genetics and genomics within grass species.

TI Time-resolved pump-probe experiments at the LCLS SO OPTICS EXPRESS LA English DT Article ID TIMING-JITTER; SPECTROMETER; RESOLUTION; DYNAMICS; LASER AB The first time-resolved x-ray/optical pump-probe experiments at the SLAC Linac Coherent Light Source (LCLS) used a combination of feedback methods and post-analysis binning techniques to synchronize an ultrafast optical laser to the linac-based x-ray laser. Transient molecular nitrogen alignment revival features were resolved in time-dependent x-ray-induced fragmentation spectra. These alignment features were used to find the temporal overlap of the pump and probe pulses. The strong-field dissociation of x-ray generated quasi-bound molecular dications was used to establish the residual timing jitter. This analysis shows that the relative arrival time of the Ti:Sapphire laser and the x-ray pulses had a distribution with a standard deviation of approximately 120 fs. The largest contribution to the jitter noise spectrum was the locking of the laser oscillator to the reference RF of the accelerator, which suggests that simple technical improvements could reduce the jitter to better than 50 fs.

TI One-dimensional hard x-ray field retrieval using a moveable structure SO OPTICS EXPRESS LA English DT Article ID TRANSVERSE TRANSLATION DIVERSITY; PHASE-RETRIEVAL; MICROSCOPY AB We present a technique that allows measuring the field of an x-ray line focus using far-field intensity measurements only. One-dimensional phase retrieval with transverse translation diversity is used to recover a hard x-ray beam focused by a compound kinoform lens. The reconstruction is found to be in good agreement with independent knife-edge scan measurements taken at separated planes. The approach avoids the need for measuring the beam profile at focus and allows narrower beams to be measured than the traditional knife-edge scan.

We find that silver grows in a Stranski-Krastanov mode with a two monolayer thin wetting layer which takes on a p(7X7) reconstruction at temperatures lower than 700 K and a (root 52 X root 52)R13.9 degrees reconstruction at higher temperatures. The occurrence of the two distinct reconstructions is shown to have profound implications for the growth characteristics of films exhibiting thicknesses of one and two monolayers. The nanoscale I(V) characteristics of the films were analyzed by means of multiple-scattering calculations based on dynamical LEED theory. Furthermore, the vertical interatomic spacing at the interface between the Ag film and the Ni substrate was determined to (2.8 perpendicular to 0.1) angstrom for all film thicknesses (<13 ML) while the uppermost silver layer relaxes by about (4 +/- 1)% toward the crystal.

TI Pair correlations in the neutrinoless double-beta decay candidate Te-130 SO PHYSICAL REVIEW C LA English DT Article ID MASS; ISOTOPES AB Pair correlations in the ground state of Te-130 have been investigated using pair-transfer experiments to explore the validity of approximations in calculating the matrix element for neutrinoless double-beta decay. This nucleus is a candidate for the observation of such decay, and a good understanding of its structure is crucial for eventual calculations of the neutrino mass, should such a decay indeed be observed. For proton-pair adding, strong transitions to excited 0(+) states had been observed in the Te isotopes by Alford et al. [Nucl. Phys. A 323, 339 (1979)], indicating a breaking of the BCS approximation for protons in the ground state. We measured the neutron-pair removing (p,t) reaction on Te-130 and found no indication of a corresponding splitting of the BCS nature of the ground state for neutrons. C1 [Bloxham, T.; Freedman, S.

CA D0 Collaboration TI Evidence for an anomalous like-sign dimuon charge asymmetry SO PHYSICAL REVIEW D LA English DT Article ID MODEL CP-VIOLATION; BARYON ASYMMETRY; DETECTOR; PHYSICS AB We measure the charge asymmetry A of like-sign dimuon events in 6.1 fb(-1) of p (p) over bar collisions recorded with the D0 detector at a center-of-mass energy root s = 1.96 TeV at the Fermilab Tevatron collider. From A, we extract the like-sign dimuon charge asymmetry in semileptonic b-hadron decays: A(sl)(b) = -0.00957 +/- 0.00251 (stat) +/- 0.00146 (syst). This result differs by 3.2 standard deviations from the standard model prediction A(sl)(b)(SM) = (-2.3(0.6)(+0.5)) x 10(-4) and provides first evidence of anomalous CP violation in the mixing of neutral B mesons.

TI Evidence for an Anomalous Like-Sign Dimuon Charge Asymmetry SO PHYSICAL REVIEW LETTERS LA English DT Article ID MODEL CP-VIOLATION; BARYON ASYMMETRY AB We measure the charge asymmetry A =(N(++) -N(--))/(N(++) + N(--)) of like-sign dimuon events in 6.1 fb(-1) of p (p) over bar collisions recorded with the D0 detector at a center-of-mass energy root s = 1: 96 TeV at the Fermilab Tevatron collider. From A we extract the like-sign dimuon charge asymmetry in semileptonic b-hadron decays: A(sl)(b) = -0.009 57 +/- 0.00251(stat) +/- 0.001 46(sys). It differs by 3.2 standard deviations from the standard model prediction A(sl)(b)(SM) = (-2.3(-0.6)(+0.5)) x 10(-4), and provides first evidence of anomalous CP violation in the mixing of neutral B mesons.

Remarkably, the entanglement entropy can be expressed in a simple separable form S = S-G + S-F, with S-F the entanglement entropy of a free Majorana fermion system and SG that of a Z(2) gauge field. The Z(2) gauge field part contributes to the universal "topological entanglement entropy" of the ground state while the fermion part is responsible for the nonlocal entanglement carried by the Z(2) vortices (visons) in the non-Abelian phase. Our result also enables the calculation of the entire entanglement spectrum and the more general Renyi entropy of the Kitaev model. Based on our results we propose a new quantity to characterize topologically ordered states-the capacity of entanglement, which can distinguish the states with and without topologically protected gapless entanglement spectrum.

Zhang, Dianlin TI Strong nonlinearity and hysteresis of Hall resistance versus magnetization in nickel thin films SO PHYSICS LETTERS A LA English DT Article DE Anomalous Hall effect; Nickel thin film; Hall resistivity; Hysteresis ID BERRY-PHASE; FERROMAGNETICS; MANGANITES AB The anomalous Hall effect (AHE) in ferromagnetic materials is perhaps one of the oldest unresolved mysteries in physics. First observed in 1881, its mechanism is still a controversial topic today. The question remains whether AHE is caused by intrinsic (Berry phase and band structure) or extrinsic (defect scattering) effects or a combination of both. Here we present experimental observation in nickel thin films that seems to add to the mystery, but may in fact provide crucial clues for ultimately resolving the controversy. The key observation is that the Hall resistivity of nickel films is a strongly nonlinear function of the magnetization and displays clear hysteresis with respect to M. Specifically, at low temperatures, the anomalous Hall coefficient switches between two saturated values under the magnetic field with a narrow transition region, but with a strong hysteresis, in contrast to the slow saturation of the magnetization. The nonlinearity and the hysteresis become more apparent with decreasing temperature or film thickness. Despite the simplicity of the lattice and magnetic structure of nickel films, these results are outside our current understanding of AHE, whether using intrinsic or extrinsic mechanisms of AHE. It presents a challenge for these models, and may be used as a test of validity for both types of theories. (C) 2010 Elsevier B.V. All rights reserved.

In order to address the recent globalization of scientific research, we also focused on four key indicators of research activities: research and development (R&D) funding, total science and engineering doctoral degrees, patents, and scientific publications. We compared these indicators across three major population and economic regions: the US, the European Union (EU) and the People's Republic of China (China) over the past decade. We discovered a number of interesting trends with direct relevance for science policy. The level of US FRF has varied between 0.2% and 0.6% of the GDP during the last six decades. Since the 1960s, the US FRF contribution has fallen from twice that of industrial research funding to roughly equal. Also, in the last two decades, the portion of the US government R&D spending devoted to research has increased. Although well below the US and the EU in overall funding, the current growth rate for R&D funding in China greatly exceeds that of both. Finally, the EU currently produces more science and engineering doctoral graduates and scientific publications than the US in absolute terms, but not per capita. This study's aim is to facilitate a serious discussion of key questions by the research community and federal policy makers. In particular, our results raise two questions with respect to: a) the increasing globalization of science: "What role is the US playing now, and what role will it play in the future of international science?''; and b) the ability to produce beneficial innovations for society: "How will the US continue to foster its strengths?''

Our data show that the reaction is highly selective, rapid, reversible, and efficient. Among 20 amino acids, only cysteine is reactive toward Se-N containing reagents and the reaction occurs in seconds. With the addition of dithiothreitol, peptides derivatized by selenium reagents can be recovered. The high reaction selectivity and reversibility provide potential in both selective identification and isolation of thiols from mixtures. Also, with dependence on the selenium reagent used, derivatized peptide ions exhibit tunable dissociation behaviors (either facile cleavage or preservation of the formed Se-S bond upon collision-induced dissociation), a feature that is useful in proteomics studies. Equally importantly, the thiol derivatization yield is striking, as reflected by 100% conversion of protein beta-lactoglobulin A using ebselen within 30 s. In addition, preliminary applications such as rapid screening of thiol peptides from mixtures and identification of the number of protein free and bound thiols have been demonstrated. The unique selenium chemistry uncovered in this study would be valuable in the MS analysis of thiols and disulfide bonds of proteins/peptides.

TI Analyte Discrimination from Chemiresistor Response Kinetics SO ANALYTICAL CHEMISTRY LA English DT Article ID VOLATILE ORGANIC-COMPOUNDS; POLYMER COMPOSITES; CHEMICAL SENSORS; RESISTIVITY; SOLUBILITY; SORPTION; ARRAYS AB Chemiresistors are polymer-based sensors that transduce the sorption of a volatile organic compound into a resistance change. Like other polymer-based gas sensors that function through sorption, chemiresistors can be selective for analytes on the basis of the affinity of the analyte for the polymer. However, a single sensor cannot, in and of itself, discriminate between analytes, since a small concentration of an analyte that has a high affinity for the polymer might give the same response as a high concentration of another analyte with a low affinity. In this paper we use a field-structured chemiresistor to demonstrate that its response kinetics can be used to discriminate between analytes, even between those that have identical chemical affinities for the polymer phase of the sensor. The response kinetics is shown to be independent of the analyte concentration, and thus the magnitude of the sensor response, but is found to vary inversely with the analyte's saturation vapor pressure. Saturation vapor pressures often vary greatly from analyte to analyte, so analysis of the response kinetics offers a powerful method for obtaining analyte discrimination from a single sensor.

The superior signal brightness and high photostability of quantum dots are combined with the promising advantages of a lateral flow test strip and result in high sensitivity and selectivity and speed for protein detection. Nitrated ceruloplasmin, a significant biomarker for cardiovascular disease, lung cancer, and stress response to smoking, was used as model protein biomarker to demonstrate the good performances of this proposed quantum dot-based lateral flow test strip. Quantitative detection of nitrated ceruloplasmin was realized by recording the fluorescence intensity of quantum dots captured on the test line. Under optimal conditions, this portable fluorescence biosensor displays rapid responses for nitrated ceruloplasmin with the concentration as low as 1 ng/mL. Furthermore, the biosensor was successfully utilized for spiked human plasma sample detection in a wide dynamic range with a detection limit of 8 ng/mL (S/N = 3). The results demonstrate that the quantum dot-based lateral flow test strip is capable of rapid, sensitive, and quantitative detection of nitrated ceruloplasmin and hold a great promise for point-of-care and in field analysis of other protein biomarkers.

As a result, it would be beneficial to have a platform to produce them in a high-throughput format for drug screening. We have developed a miniaturized fluid array device for cell-free protein synthesis, and the device was exploited to produce both soluble and membrane proteins. Two membrane-associated proteins, bacteriorhodopsin and ApoA lipoprotein, were coexpressed in an expression medium in the presence of lipids. Simultaneous expression of ApoA lipoprotein enhanced the solubility of bacteriorhodopsin and would facilitate functional studies. In addition, the device was employed to produce two enzymes, luciferase and beta-lactamase, both of which were demonstrated to be compatible with enzyme inhibition assays. beta-lactamase, a drug target associated with antibiotic resistance, was further used to show the capability of the device for drug screening. beta-Lactamase was synthesized in the 96 units of the device and then assayed by a range of concentrations of four mock drug compounds without harvesting and purification. The inhibitory effects of these compounds on beta-lactamase were measured in a parallel format, and the degree in their drug effectiveness agreed well with the data in the literature. This work demonstrated the feasibility of the use of the fluid array device and cell-free protein expression for drug screening, with advantages in less reagent consumption, shorter analysis time, and higher throughput.

Most, if not all, sequenced metagenomes are complex mixtures of chromosomal and plasmid sequence fragments from multiple organisms, possibly from different kingdoms. Computational methods for prediction of genomic elements such as genes are significantly different for chromosomes and plasmids, hence raising the need for separation of chromosomal from plasmid sequences in a metagenome. We present a program for classification of a metagenome set into chromosomal and plasmid sequences, based on their distinguishing pentamer frequencies. On a large training set consisting of all the sequenced prokaryotic chromosomes and plasmids, the program achieves similar to 92% in classification accuracy. On a large set of simulated metagenomes with sequence lengths ranging from 300 bp to 100 kbp, the program has classification accuracy from 64.45% to 88.75%. On a large independent test set, the program achieves 88.29% classification accuracy.

It is well documented that the effective diffusion coefficient can vary by location in a biofilm. The current literature is dominated by effective diffusion coefficient measurements for distinct cell clusters and stratified biofilms showing this spatial variation. Regardless of whether distinct cell clusters or surface-averaging methods are used, position-dependent measurements of the effective diffusion coefficient are currently: (1) invasive to the biofilm, (2) performed under unnatural conditions, (3) lethal to cells, and/or (4) spatially restricted to only certain regions of the biofilm. Invasive measurements can lead to inaccurate results and prohibit further (time-dependent) measurements which are important for the mathematical modeling of biofilms. In this study our goals were to: (1) measure the effective diffusion coefficient for water in live biofilms, (2) monitor how the effective diffusion coefficient changes over time under growth conditions, and (3) correlate the effective diffusion coefficient with depth in the biofilm. We measured in situ two-dimensional effective diffusion coefficient maps within Shewanella oneidensis MR-1 biofilms using pulsed-field gradient nuclear magnetic resonance methods, and used them to calculate surface-averaged relative effective diffusion coefficient (D(rs)) profiles. We found that (1) D(rs) decreased from the top of the biofilm to the bottom, (2) D(rs) profiles differed for biofilms of different ages, (3) D(rs) profiles changed over time and generally decreased with time, (4) all the biofilms showed very similar D(rs) profiles near the top of the biofilm, and (5) the D(rs) profile near the bottom of the biofilm was different for each biofilm. Practically, our results demonstrate that advanced biofilm models should use a variable effective diffusivity which changes with time and location in the biofilm. Biotechnol.

On the basis of experimental information, the surface charge density of the spores is estimated at 0 03 mu C/cm(2) at 20% relative humidity and decreases with increasing humidity The Coulombic force is introduced for the spore-mica system (both charged, nonconductive surfaces), and an electrostatic image force is introduced to the spore-gold system because gold is electrically conductive The Coulombic force for spore mica is repulsive because the components are similarly charged, while the image force for the spore-gold system is attractive The magnitude of both forces decreases with increasing humidity The electrostatic forces are added to other force components, e g., van der Waals and capillary forces, to obtain the adhesion force for each system The adhesion forces measured by AFM are compared to the estimated values It is shown that the electrostatic (Coulombic and image) forces play a significant role in the adhesion force between spores and planar surfaces.

TI Effects of Plug-In Hybrid Electric Vehicles on Ozone Concentrations in Colorado SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article AB This study explores how ozone concentrations in the Denver, CO area might have been different if plug-in hybrid electric vehicles (PHEVs) had replaced light duty gasoline vehicles in summer 2006. A unit commitment and dispatch model was used to estimate the charging patterns of PHEVs and dispatch power plants to meet electricity demand Emission changes were estimated based on gasoline displacement and the emission characteristics of the power plants providing additional electricity The Comprehensive Air Quality Model with extensions (CAMx) was used to simulate the effects of these emissions changes on ozone concentrations. Natural gas units provided most of the electricity used for charging PHEVs in the scenarios considered With 100% PHEV penetration, nitrogen oxide (NOx) emissions were reduced by 27 tons per day (tpd) from a fleet of 17 million vehicles and were increased by 3 tpd from power plants; VOC emissions were reduced by 57 tpd These emission changes reduced modeled peak 8-h average ozone concentrations by approximately 2-3 ppb on most days Ozone concentration increases were modeled for small areas near central Denver Future research is needed to forecast when significant PHEV penetration may occur and to anticipate characteristics of the corresponding power plant and vehicle fleets.

Three nanoporous sorbents containing chelating diamine functionalities were evaluated for Cu(2+) adsorption from natural waters ethylenediamine functionalized self-assembled monolayers on mesoporous supports (EDA-SAMMS), ethylenediamine functionalized activated carbon (AC-CH(2)-EDA), and 1,10-phenanthroline functionalized mesoporous carbon (Phen-FMC). The pH dependence of Cu(2+) sorption, Cu(2+) sorption capacities, rates, and selectivity of the sorbents were determined and compared with those of commercial sorbents (Chelex-100 ion-exchange resin and Darco KB-B activated carbon) All three chelating diamine sorbents showed excellent Cu(2+) removal (similar to 95-99%) from river water and seawater over the pH range 6.0-8.0 EDA-SAMMS and AC-CH(2)-EDA demonstrated rapid Cu(2+) sorption kinetics (minutes) and good sorption capacities (26 and 17 mg Cu/g sorbent, respectively) in seawater, whereas Phen-FMC had excellent selectivity for Cu(2+) over other metal ions le g., Ca(2+), Fe(2+), Ni(2+), and Zn(2+)) and was able to achieve Cu below the EPA recommended levels for river and sea waters.

The solubility constant in logarithmic units at 25 degrees C for the following reaction, Mg3Cl(OH)(5) center dot 4H(2)O + 5H(+) = 3Mg(2+) + 9H(2)O(I) + Cl- is calculated as 43.21 +/- 0.33 (2 sigma) based on the specific interaction theory (SIT) model for extrapolation to infinite dilution. The Gibbs free energy and enthalpy of formation for phase 5 at 25 degrees C are derived as -3384 +/- 2 (2 sigma) kJ mol(-1) and -3896 +/- 6 (2 sigma) kJ mol(-1), respectively. MgO (bulk, pure MgO corresponding to the mineral periclase) is the only engineered barrier certified by the Environmental Protection Agency (EPA) for emplacement in the Waste Isolation Pilot Plant (WIPP) in the US, and an Mg(OH)(2)-based engineered barrier (bulk, pure Mg(OH)(2) corresponding to brucite) is to be employed in the Asse repository in Germany. Phase 5, and its similar phase, phase 3 (Mg2Cl(OH)(3)center dot 4H(2)O), could have a significant role in influencing the geochemical conditions in geological repositories for nuclear waste in salt formations where MgO or brucite is employed as engineered barriers. Based on our solubility constant for phase 5 in combination with the literature value for phase 3, we predict that the composition for the invariant point of phase 5 and phase 3 would be m(Mg) = 1.70 and pmH = 8.94 in the Mg-Cl binary system. The recent WIPP Compliance Recertification Application Performance Assessment Baseline Calculations indicate that phase 5, instead of phase 3, is indeed a stable phase when the WIPP Generic Weep Brine (GWB), a Na-Mg-Cl-dominated brine associated with the Salado Formation, equilibrates with actinide-source-term phases, brucite, magnesium carbonates, halite and anhydrite. Therefore, phase 5 is important to the WIPP, and potentially important to other repositories in salt formations. (C) 2010 Elsevier Ltd. All rights reserved.

The thin films are synthesized by the magnetron cosputtering method. We find that due to the amorphous nature, the Cu-to-W ratio in the films can be varied without the limit of the solubility (or phase separation) under appropriate conditions. As a result, the band gap and conductivity type of the films can be tuned by controlling the film composition. Unfortunately, the amorphous copper tungsten oxides are not stable in aqueous solution and are not suitable for the application of photoelectrochemical splitting of water. Nonetheless, it provides an alternative approach to search for transition metal oxides with tunable band gaps. (C) 2010 American Institute of Physics.

TI Consequences of the magnetocaloric effect on magnetometry measurements SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID POWDER-METALLURGY; TEMPERATURE; GD5SI2GE2; LA(FE; CO AB Magnetization curves recorded at high sweep-rates on magnetic materials near a phase transition temperature can be affected by temperature changes in the material due to the magnetocaloric effect. This change in the sample temperature is a result of the quasiadiabatic conditions that can occur under such conditions and we demonstrate its effects on magnetization curves of two magnetocaloric materials, La(Fe(0.945)Co(0.055))(11.9)Si(1.1) and Gd(5)Si(2)Ge(2). We show how a quantity calculated from isothermal magnetization curves, the magnetic entropy change, Delta S(M), is affected by the erroneous data. As Delta S(M) is a measure of the magnetocaloric effect, the discrepancies demonstrated here are more severe close to a peak in Delta S(M), which is precisely the quantity that is of interest and reported on in the literature from possibly erroneous magnetization data. We also demonstrate how, through simple measurements and without a direct measurement of the sample temperature, one can determine an appropriate sweep-rate of the magnetic field.

TI Structure of the (0001) basal twin boundary in Bi2Te3 SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID THERMOELECTRIC PROPERTIES; POLYCRYSTALLINE SILICON; ELECTRONIC-STRUCTURE; BISMUTH TELLURIDE; HOT EXTRUSION; PSEUDOPOTENTIALS; REFINEMENT; COMPOUND; ALLOYS; TE AB We investigate the structure of the (0001) basal twin boundary in Bi2Te3. Electron diffraction measurements show that this interface corresponds to a 180 degrees rotation of the crystal about the [0001] axis, an alignment that reverses the stacking of the basal planes. The basal planes in the perfect Bi2Te3 structure are arranged in a repeating sequence of five-layer wide Te-(1)-Bi-Te-(2)-Bi-Te-(1) packets. Thus, it is possible for the twin interface to be located at one of three distinct locations: at the Te-(2) layer, the Bi layer, or the Te-(1) layer. Using aberration-corrected high-angle annular dark field scanning transmission electron microscopy, we show that the twin boundary is terminated at the Te-(1) layer, where the stacking forms a double-layer of Te. Our observations are consistent with ab initio calculations, which predict this twin termination to have the lowest interfacial energy of the three configurations we considered. Our calculations and observations also find a small expansion in the interplanar spacing at the interface. (C) 2010 American Institute of Physics. [doi:10.1063/1.3457902] C1 [Medlin, D.

The pyroelectric coefficient strongly increases with the wire radius decrease and diverges at critical radius R corresponding to the size-driven transition into paraelectric phase. Size-driven enhancement of pyroelectric coupling leads to the giant pyroelectric current and voltage generation by the polarized ferroelectric nanoparticles in response to the temperature fluctuation. The maximum efficiency of the pyroelectric energy harvesting and bolometric detection is derived, and is shown to approach the Carnot limit for low temperatures.

TI Demonstration of a plasma mirror based on a laminar flow water film SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID PULSE DURATION; LASER-PLASMA; INTENSITY; SUPPRESSION; TARGET; JET AB A plasma mirror based on a laminar water film with low flow speed (0.5-2 cm/s) has been developed and characterized, for use as an ultrahigh intensity optical reflector. The use of flowing water as a target surface automatically results in each laser pulse seeing a new interaction surface and avoids the need for mechanical scanning of the target surface. In addition, the breakdown of water does not produce contaminating debris that can be deleterious to vacuum chamber conditions and optics, such as is the case when using conventional solid targets. The mirror exhibits 70% reflectivity, while maintaining high-quality of the reflected spot. (C) 2010 American Institute of Physics.

TI Real space mapping of polarization dynamics and hysteresis loop formation in relaxor-ferroelectric PbMg1/3Nb2/3O3-PbTiO3 solid solutions SO JOURNAL OF APPLIED PHYSICS LA English DT Article; Proceedings Paper CT 4th International Workshop and Satellite Symposium on Piezoresponse Force Microscopy and Nanoscale Phenomena in Polar Materials CY JUN 23-27, 2009 CL Aveiro, PORTUGAL ID SINGLE-CRYSTALS; FORCE MICROSCOPY; PB(MG1/3NB2/3)O-3-PBTIO3; DISORDER; DOMAINS; PHASE AB Polarization switching in ergodic relaxor and ferroelectric phases in the PbMg1/3Nb2/3O3-PbTiO3 (PMN-PT) system is studied using piezoresponse force microscopy, single point electromechanical relaxation measurements, and voltage spectroscopy mapping. The dependence of relaxation behavior on voltage pulse amplitude and time is found to follow a universal logarithmic behavior with a nearly constant slope. This behavior is indicative of the progressive population of slow relaxation states, as opposed to a linear relaxation in the presence of a broad relaxation time distribution. The role of relaxation behavior, ferroelectric nonlinearity, and the spatial inhomogeneity of the tip field on hysteresis loop behavior is analyzed in detail. The hysteresis loops for ergodic PMN-10%PT are shown to be kinetically limited, while in PMN with larger PT content, true ferroelectric hysteresis loops with low nucleation biases are observed.

TI Defects in gallium nitride nanowires: First principles calculations SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID CHEMICAL-VAPOR-DEPOSITION; GAN NANOWIRES; NATIVE DEFECTS; COMPLEXES; EPITAXY; GROWTH; ARRAYS AB Atomic configurations and formation energies of native defects in an unsaturated GaN nanowire grown along the [001] direction and with (100) lateral facets are studied using large-scale ab initio calculation. Cation and anion vacancies, antisites, and interstitials in the neutral charge state are all considered. The configurations of these defects in the core region and outermost surface region of the nanowire are different. The atomic configurations of the defects in the core region are same as those in the bulk GaN, and the formation energy is large. The defects at the surface show different atomic configurations with low formation energy. Starting from a Ga vacancy at the edge of the side plane of the nanowire, a N-N split interstitial is formed after relaxation. As a N site is replaced by a Ga atom in the suboutermost layer, the Ga atom will be expelled out of the outermost layers and leaves a vacancy at the original N site. The Ga interstitial at the outmost surface will diffuse out by interstitialcy mechanism. For all the tested cases N-N split interstitials are easily formed with low formation energy in the nanowires, indicating N(2) molecular will appear in the GaN nanowire, which agrees well with experimental findings.

TI III-nitride nanopyramid light emitting diodes grown by organometallic vapor phase epitaxy SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID GAN NANOWIRES; DIFFRACTION CONTRAST; STACKING-FAULTS; NANOROD ARRAYS; EMISSION; SEMICONDUCTORS; LUMINESCENCE; EFFICIENCY; SHIFT; FILMS AB Nanopyramid light emitting diodes (LEDs) have been synthesized by selective area organometallic vapor phase epitaxy. Self-organized porous anodic alumina is used to pattern the dielectric growth e templates via reactive ion etching, eliminating the need for lithographic processes. (In,Ga)N quantum well growth occurs primarily on the six {1 (1) over bar 01} semipolar facets of each of the nanopyramids, while coherent (In,Ga)N quantum dots with heights of up to similar to 20 nm are incorporated at the apex by controlling growth conditions. Transmission electron microscopy (TEM) indicates that the (In,Ga)N active regions of the nanopyramid heterostructures are completely dislocation-free. Temperature-dependent continuous-wave photoluminescence of nanopyramid heterostructures yields a peak emission wavelength of 617 nm and 605 nm at 300 K and 4 K respectively. The peak emission energy varies with increasing temperature with a double S-shaped profile, which is attributed to either the presence of two types of InN-rich features within the nanopyramids or a contribution from the commonly observed yellow defect luminescence close to 300 K. TEM cross-sections reveal continuous planar defects in the (In,Ga)N quantum wells and GaN cladding layers grown at 650-780 degrees C, present in 38% of the nanopyramid heterostructures. Plan-view TEM of the planar defects confirms that these defects do not terminate within the nanopyramids. During the growth of p-GaN, the structure of the nanopyramid LEDs changed from pyramidal to a partially coalesced film as the thickness requirements for an undepleted p-GaN layer result in nanopyramid impingement. Continuous-wave electroluminescence of nanopyramid LEDs reveals a 45 nm redshift in comparison to a thin-film LED, suggesting higher InN incorporation in the nanopyramid LEDs. These results strongly encourage future investigations of III-nitride nanoheteroepitaxy as an approach for creating efficient long wavelength LEDs. (C) 2010 American Institute of Physics.

TI Synthesis and Electrospun Fiber Mats of Low T-g Poly(propylene fumerate-co-propylene maleate) SO JOURNAL OF APPLIED POLYMER SCIENCE LA English DT Article DE biomaterials; copolymerization; crosslinking; fibers; polyesters ID IN-VITRO DEGRADATION; COMPOSITE SCAFFOLDS; CROSS-LINKING; FUMARATE); BONE; NETWORKS; FABRICATION AB Many publications have examined the biodegradable polymer poly(propylene fumate) (PPF) for use in tissue engineering applications. We have examined a similar crosslinkable polymer system, poly(propylene fumerate)-co-(propylene maleate) (PPFcPM), derived from maleic anhydride (MA) and 1,2-propylene diol (PD). This copolymer system uses a less expensive monomer as well as leads to varied ratios of fumerate to maleate groups, allowing tuning of the crosslinked polymer properties such as degradation rate. Two different reaction conditions were used to synthesize the copolymer from MA and PD. In the first case (Method A), toluene was used as a solvent to azeotropically (85 degrees C) remove water to drive the acid catalyzed esterification reaction. In the second case (Method B), the initial ring opening reaction was conducted, followed by addition of catalyst and removal of water to produce polymer of higher molecular weight. Both polymer systems had glass transition temperatures (T-g) below room temperature. The low T-g PPFcPM was dissolved in chloroform along with the photoinitiator phenylbis(2,4,6-trimethylbenzoy1)-phosphine oxide (BAPO) and electrospun. The polymer fibers were crosslinked soon after they formed to produce noncalendaring 3D porous scaffolds. Control experiments without the BAPO photoinitiator did not produce fiber mats.

The investigated lipid monolayers have been studied with and without the 10(-3) M solution of beta-CD in the aqueous subphase. The surface pressure-area (pi-A) isotherms and the relaxation of the monolayers (surface pressure-time curves) were monitored. Our experiments reveal that there is not impact of beta-CD on the packing properties of the DPPC monolayers, while the presence of beta-CD in subphase changes the in-plane organization of SM molecules. Monolayers composed of pure chol molecules have been rapidly affected by the presence of the beta-CD in the subphase. Our data show that beta-CD can complex and desorb one-chain phospholipid (lyso-PC) but this process is relatively slow and, as indicated by the GIXD data, beta-CD molecules are present at the air/water interface. Subtraction of cholesterol by the beta-CD from mixed binary systems containing SM/chol (70/30, 50/50 and 30/70 mol ratio) and DPPC/chol (70/30 and 50/50 mol ratio) has also been investigated. Our experiments proved that cholesterol can be removed from the mixed monolayers only when it is unbound. The beta-CD was not capable to distract the monolayers of the SM/chol, forming a stable complex of the 2:1 stoichiometry (as observed in the model lipid raft). Interestingly, at the surface pressure of 30 mN/m also at the molar proportion of 50/50 no cholesterol removal was observed. This was interpreted by relatively strong SM/chol interactions and the tight packing of the mixed monolayer. For model membranes, in which cholesterol was in large excess (SM/chol, 30/70) the beta-CD extraction of cholesterol was observed, and the membrane composition evolves towards the lipid proportion corresponding to the stable complex stoichiometry (SM/chol 2:1).

First, when measuring ORR voltammetry, adsorption processes are superimposed on the current. Second, the system resistance causes an Ohmic drop that may have a profound effect on the measured curves, especially at the higher currents close to the diffusion limiting current. More importantly, we show that it also influences the kinetic part of the potential curve in such a way that the Tafel slope may be determined incorrectly when failing to correct for Ohmic drop. Finally, because electrolyte resistance lowers with increasing temperature, failure to compensate for Ohmic drop may lead to erroneous conclusions about the temperature-dependent activity of a catalyst as well as the corresponding activation energies.

Classical rubber elasticity theories, however, do not admit such behavior. Here, we investigate a modification of the assumptions of classical elasticity theory to reconcile this discrepancy. We present an analysis of the consequences of assuming that chain forces are nonzero only for chain extension relative to the unstrained state, in contrast to the classical elasticity theory, which assumes that the chain force is directly proportional to the chain end-to-end distance (an entropic spring). Assuming an affine transformation of the network node coordinates, we derive two modulus discontinuity factors between compression and extension: D(1), based on the differing number of network chains being extended and D(2), based on the average differential chain extension. The discontinuities arise due to geometric effects, inherent in the affine transformation between compressive and extensive strains. We find that D(1), the ratio of the numbers of participating chains (compressive/extensive = 1.37), suffices to account for the experimentally observed modulus discontinuity in natural rubber of 1.34.

The effluents from 15 different gasification facilities were considered to assess the impact of fuel composition on anode susceptibility to contamination. For each syngas case, the study considers the magnitude of contaminant exposure resulting from operation of a warm gas cleanup unit at two different temperatures and operation of a nickel-based SOFC at three different temperatures. Contaminant elements arsenic (As), phosphorous (P), and antimony (Sb) are predicted to be present in warm gas cleanup effluent and will interact with the nickel (Ni) components of a SOFC anode. Phosphorous is the trace element found in the largest concentration of the three contaminants and is potentially the most detrimental. Poisoning was found to depend on the composition of the syngas as well as system operating conditions. Results for all trace elements tended to show invariance with cleanup operating temperature, but results were sensitive to syngas bulk composition. Synthesis gas with high steam content tended to resist poisoning. Published by Elsevier B.V.

A previous model is updated to include for the first time the use of experimentally measured capillary pressure-saturation relationships through the introduction of a Gaussian contact-angle distribution into the property equations. The updated model is used to simulate various limiting-case scenarios of water and gas transport in fuel-cell diffusion media. Analysis of these results demonstrate that interfacial conditions are more important than bulk transport in these layers, where the associated mass-transfer resistance is the result of higher capillary pressures at the boundaries and the steepness of the capillary pressure-saturation relationship. The model is also used to examine the impact of a microporous layer, showing that it dominates the response of the overall diffusion medium. In addition, its primary mass-transfer-related effect is suggested to be limiting the water-injection sites into the more porous gas-diffusion layer. (C) 2010 Elsevier B.V. All rights reserved.

Mechanical flaws were characterized by laser damage testing, as well as by optical, secondary electron, and photoluminescence microscopy. Localized polishing, chemical leaching, and the control of indentation morphology were used to isolate the structural features that limit optical damage. A thin defect layer on fracture surfaces, including those smaller than the wavelength of visible light, was found to be the dominant source of laser damage initiation during illumination with 355 nm, 3 ns laser pulses. Little evidence was found that either displaced or densified material or fluence intensification plays a significant role in optical damage at fluences >35 J/cm(2). Elimination of the defect layer was shown to increase the overall damage performance of fused silica optics. (C) 2010 Optical Society of America C1 [Miller, P. E.; Bude, J. D.; Suratwala, T.

The electronic structure thus obtained shows a strong hybridization of W d and 0 p orbitals giving rise to relatively broad bands which are similar to other scheelite tungstates. Structural parameters obtained from Rietveld refinement of X-ray powder diffraction pattern recorded for high quality NBW crystal were further optimized by WIEN2K. Calculations using the generalized gradient approximation (GGA) show that this material exhibits an indirect band gap of 3.2 +/- 0.1 eV.

Huge relaxation steps are observed across different loops in the low temperature magnetization isotherms. Giant relaxation present in this system indicates the existence of incubation time to get the saturated moment at a certain field. Measurement protocol sensitive magnetization behavior observed in this system may arise from the strong magnetostructural coupling and/or magnetic frustration. Electrical resistivity and magnetoresistance also reflect the magnetic state of the compound. Magnetocaloric effect is found to be large at temperatures close to the magnetic transition temperature.

To understand the evolution of HIV-1 pot and env genes in viremic patients under selective pressure of ART, we performed longitudinal analyses of plasma-derived pol and env sequences from single HIV-1 genomes. We tested the hypotheses that drug resistance in pol was unrelated to changes in coreceptor usage (tropism), and that recombination played a role in evolution of viral strains. Recombinants were identified by using Bayesian and other computational methods. High-level genotypic resistance was seen in similar to 70% of X4 and R5 strains during ART. There was no significant association between resistance and tropism. Each patient displayed at least one recombinant encompassing env and representing a change in predicted tropism. These data suggest that, in addition to mutation, recombination can play a significant role in shaping HIV-1 evolution. (C) 2010 Elsevier Inc. All rights reserved.

Molecular studies have demonstrated that L(pro) inhibits translation of host capped mRNAs and transcription of some genes involved in the innate immune response. We have used microarray technology to study the gene expression profile of bovine cells infected with wild type (WT) or leaderless FMDV. Thirty nine out of approximately 22,000 bovine genes were selectively up-regulated by 2 fold or more in leaderless versus WT virus infected cells. Most of the up-regulated genes corresponded to IFN-inducible genes, chemokines or transcription factors. Comparison of promoter sequences suggested that host factors NF-kappa B, ISGF3G and IRF1 specifically contributed to the differential expression, being NF-kappa B primarily responsible for the observed changes. Our results suggest that L(pro) plays a central role in the FMDV evasion of the innate immune response by inhibiting NF-kappa B dependent gene expression. Published by Elsevier Inc.

Here an invariant residue (Ile 309) was replaced with Leu in 7 subtype C patient-derived Envs from recent infection and 4 related neutralizing antibody escape variants that emerged later. For these 11 Envs, 1309L did not alter replication in primary CD4 T cells; however, replication in monocyte-derived macrophages was enhanced. Infection of cell lines with low CD4 or CCR5 revealed that 1309L enhanced utilization of CD4 but did not affect the ability to use CCR5. This CD4-enhanced phenotype tracked with sensitivity to sCD4, indicating increased exposure of the CD4 binding site. The results suggest that Ile 309 preserves a V3-mediated masking function that occludes the CD4 binding site. The findings point to an immune evasion strategy in subtype C Env to protect this vulnerable immune target. (C) 2010 Elsevier Inc. All rights reserved.

TI Three-dimensional resistivity tomography of Vulcan's forge, Vulcano Island, southern Italy SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article ID AEOLIAN ISLANDS; FOSSA CONE; LIPARI AB 9,525 DC resistivity measurements were taken along 9 profiles crossing the volcanic edifice of La Fossa di Vulcano (the forge of God Vulcan in ancient Roman mythology), Vulcano Island (Italy) using a total of 958 electrode locations. This unique data set has been inverted in 3D by minimizing the L-2 norm of the data misfit using a Gauss-Newton approach. The true 3D inversion was performed using parallel processing on an unstructured tetrahedral mesh containing 75,549 finite-element nodes and 398,208 elements to accurately model the topography of the volcanic edifice. The 3D tomogram shows a very conductive body (>0.1 S/m) comprised inside the Pietre Cotte crater with conductive volumes that are consistent with the position of temperature and CO2 anomalies at the ground surface. This conductive body is interpreted as the main hydrothermal body. It is overlaid by a resistive and cold cap in the bottom of the crater. The position of the conductive body is consistent with the deformation source responsible for the observed 1990-1996 deflation of the volcano associated with a decrease of hydrothermal activity.

The data are interpreted using a Monte Carlo collision code that models the detailed kinematics of electron transfer reactions. The lifetimes of K(+)center dot center dot Cl(-) ion-pair states are observed to be very long, >100 mu s, and independent of binding energy. The lifetimes of strongly bound (>30 meV) K(+)center dot center dot CN(-) ion pairs are found to be similarly long but begin to decrease markedly as the binding energy is reduced below this value. This behavior is attributed to conversion of rotational energy in the CN(-) ion into translational energy of the ion pair. No long-lived K(+)center dot center dot SF(6)- ion pairs are observed, their lifetimes decreasing with increasing binding energy. This behavior suggests that ion-pair loss is associated with mutual neutralization as a result of charge transfer. (C) 2010 American Institute of Physics.

All positive ion channels, several with the same mass/charge ratio, which could be distinguished by taking the advantage of the Cl-37 isotope, have been measured at a photon resolution of nearly 6500. At the Cl 1s ionization threshold, no significant differences are reported between the absorption and the partial-ion yields. In contrast, near the 2p ionization thresholds, we detect large variations in the fragmentation patterns following excitations to the Rydberg series when comparing the atomic fragment ions to the molecular fragment ions. We attribute the different behaviours to the more-or-less diffuse nature of Rydberg states with different angular momenta. C1 [Stolte, W. C.; Demchenko, I. N.; Lindle, D.

Shimada, Kenji TI A close look at valences in hexahedral element meshes SO INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING LA English DT Article DE hexahedra; finite elements; optimization; node valence; edge valence; topology ID OPTIMIZATION; IMPROVEMENT; QUALITY AB This paper discusses using valences in objective functions for topological modification of 3D hexahedral meshes. For topological optimization of 2D quadrilateral meshes, node valence (i.e. number of element edges attached to each node) is used to maximize the number of regular nodes (i.e. nodes with four attached edges). Difficulties in developing 3D hexahedral local topology modifications have limited the success of hexahedral topology optimization, although published literature suggests using an object function based on node valence. However, in this paper, we show that node valence is not a consistent measure of good hexahedral element topology, and objective functions based on node valence can lead to element topology, which will only admit concave element shapes. Instead, we propose that objective functions based on edge valence (i.e. number of quadrilateral faces attached to each element edge) will provide a consistent measure of element topology.

We observe the formation of oriented nanoscale Ag2Te precipitates in PbTe. These precipitates initially form as coherent spherical nanoparticles and evolve into flattened semi-coherent disks during coarsening. This change in morphology is consistent with equilibrium shape theory for coherently strained precipitates. Upon annealing at elevated temperatures these precipitates eventually revert to an equiaxed morphology. We suggest this shape change occurs once the precipitates grow beyond a critical size, making it favorable to relieve the elastic coherency strains by forming interfacial misfit dislocations. These investigations of the shape and coherency of Ag2Te precipitates in PbTe should prove useful in the design of nanostructured thermoelectric materials. (C) 2010 Elsevier B.V. All rights reserved.

TI Identification of a Coiled Coil in Werner Syndrome Protein That Facilitates Multimerization and Promotes Exonuclease Processivity SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID 4-NITROQUINOLINE 1-OXIDE SENSITIVITY; RECQ HELICASE; DNA HELICASE; HRDC DOMAIN; SUBSTRATE SPECIFICITIES; EXCISION-REPAIR; CELL-LINES; KINASE; WRN; DAMAGE AB Werner syndrome (WS) is a rare progeroid disorder characterized by genomic instability, increased cancer incidence, and early onset of a variety of aging pathologies. WS is unique among early aging syndromes in that affected individuals are developmentally normal, and phenotypic onset is in early adulthood. The protein defective in WS (WRN) is a member of the large RecQ family of helicases but is unique among this family in having an exonuclease. RecQ helicases form multimers, but the mechanism and consequence of multimerization remain incompletely defined. Here, we identify a novel heptad repeat coiled coil region between the WRN nuclease and helicase domains that facilitates multimerization of WRN. We mapped a novel and unique DNA-dependent protein kinase phosphorylation site proximal to the WRN multimerization region. However, phosphorylation at this site affected neither exonuclease activity nor multimeric state. We found that WRN nuclease is stimulated by DNA-dependent protein kinase independently of kinase activity or WRN nuclease multimeric status. In addition, WRN nuclease multimerization significantly increased nuclease processivity. We found that the novel WRN coiled coil domain is necessary for multimerization of the nuclease domain and sufficient to multimerize with full-length WRN in human cells. Importantly, correct homomultimerization is required for WRN function in vivo as overexpression of this multimerization domain caused increased sensitivity to camptothecin and 4-nitroquinoline 1-oxide similar to that in cells lacking functional WRN protein.

Two trends in the aromatic selectivity, q(aromatic), were observed, depending on whether the number of carbon atoms in the spacer chain is even or odd. Linear log k' vs phi plots were obtained for each stationary phase and the S coefficient was determined from the gradient of these plots. For the phenyl type phases, the S vs n(c) plots of the retention factors of linear polycyclic aromatic hydrocarbons vs the number of rings exhibit a distinct discontinuity that between 3 and 4 rings, which increases with increasing spacer chain length for even phases but decreases for odd phases. Accordingly, we suggest that the retention factors depend differently on the number of carbon atoms in the spacer chain depending on whether this number is even or odd and that this effect is caused by different orientations of the aromatic ring relative to the silica surface.

These ligands consist of a phenyl ring tethered to the silica support via a carbon chain of length ranging from 0 to 4 atoms. The adsorption isotherm models that fit best to the data account for solute-solute interactions that are likely caused by pi-pi interactions occurring between aromatic compounds and the phenyl group of the ligand. These interactions are the dominant factor responsible for the separation of low molecular weight aromatic compounds on these phenyl-type stationary phases. The saturation capacities depend on whether the spacer of the ligands have an even or an odd number of carbon atoms, with the even alkyl chain lengths having a greater saturation capacity than the odd alkyl chain lengths. The trends in the adsorption equilibrium constant are also significantly different for the even and the odd chain length ligands. (C) 2010 Elsevier B.V. All rights reserved. C1 [Shalliker, R.

The protons are initialized with a bi-Maxwellian velocity distribution (T-p perpendicular to > T-p parallel to, where the subscripts refer to directions relative to the background magnetic field) to drive the instability. The spectra of the resulting EMIC fluctuations are characterized in terms of the wave number corresponding to the peak energy spectral density and the spectral width, both of which agree with the prediction of linear dispersion theory using instantaneous simulation values of plasma parameters. By requiring the electrons on the edge of the loss cone to be in cyclotron resonance with the wave at peak energy spectral density, the approximate condition for fast loss of relativistic electrons in the outer radiation belt due to pitch angle scattering by EMIC waves is derived. In addition, the enhanced EMIC fluctuations in the hybrid simulations are used as input waves in test particle computations to study the pitch angle scattering of relativistic electrons. The results show that fast loss of geophysically interesting relativistic electrons (<= 2 MeV) is favored in regions of relatively high plasma densities, relatively cool proton temperatures, and relatively low magnetic fields. However, the results also suggest that the loss enhancement of geophysically interesting relativistic electrons by reduced proton temperatures can be weakened and complicated by the reduction in energy densities of the enhanced EMIC fluctuations corresponding to cooler proton temperatures.

Analysis of the surface structures by a wide range of electron microscopy techniques reveals correlations between the irradiation conditions, such as the ion energy and fluence, and changes in the surface morphology. Sputtering effects play a key role in the integrity of the surface layer with increasing ion fluence. Possible mechanisms responsible for the morphological transformation are discussed, including both irradiation-induced and mechanical effects.

TI Morphological evolution of InAs/InP quantum wires through aberration-corrected scanning transmission electron microscopy SO NANOTECHNOLOGY LA English DT Article ID NUCLEATION SITES; GROWTH; STRAIN; NANOSTRUCTURES; SHAPE AB Evolution of the size, shape and composition of self-assembled InAs/InP quantum wires through the Stranski-Krastanov transition has been determined by aberration-corrected Z-contrast imaging. High resolution compositional maps of the wires in the initial, intermediate and final formation stages are presented. (001) is the main facet at their very initial stage of formation, which is gradually reduced in favour of {114} or {118}, ending with the formation of mature quantum wires with {114} facets. Significant changes in wire dimensions are measured when varying slightly the amount of InAs deposited. These results are used as input parameters to build three-dimensional models that allow calculation of the strain energy during the quantum wire formation process. The observed morphological evolution is explained in terms of the calculated elastic energy changes at the growth front. Regions of the wetting layer close to the nanostructure perimeters have higher strain energy, causing migration of As atoms towards the quantum wire terraces, where the structure is partially relaxed; the thickness of the wetting layer is reduced in these zones and the island height increases until the (001) facet is removed.

TI Muon to electron conversion: how to find an electron in a muon haystack SO PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY A-MATHEMATICAL PHYSICAL AND ENGINEERING SCIENCES LA English DT Review DE particle physics; muon to electron conversion; accelerator physics; fixed-field alternating-gradient accelerator ID DETECTOR AB The standard model (SM) of particle physics describes how the Universe works at a fundamental level. Even though this theory has proven to be very successful over the past 50 years, we know it is incomplete. Many theories that go beyond the SM predict the occurrence of certain processes that are forbidden by the SM, such as muon to electron conversion. This paper will briefly review the history of muon to electron conversion and focus on the high-precision experiments currently being proposed, COMET (Coherent Muon to Electron Transition) and Mu2e, and a next-generation experiment, PRISM. The PRISM experiment intends to use a novel type of accelerator called a fixed field alternating-gradient (FFAG) accelerator. There has recently been renewed interest in FFAGs for the Neutrino Factory and the Muon Collider, and because they have applications in many areas outside of particle physics, such as energy production and cancer therapy. The synergies between these particle physics experiments and other applications will also be discussed.

TI Heating effects in a chain of quantum dots SO PHYSICAL REVIEW B LA English DT Article ID ELECTRON-PHONON INTERACTION; GRANULAR METALS; SUPERCONDUCTORS; CONDUCTIVITY AB We study heating effects in a chain of weakly coupled grains due to electron-hole pair creation. The main mechanism for the latter at low temperatures is due to inelastic electron cotunneling processes in the array. We develop a quantitative kinetic theory for these systems and calculate the array temperature profile as a function of grain parameters, bias voltage or current, and time and show that for nanoscale size grains the heating effects are pronounced and easily measurable in experiments. In the low- and high-voltage limits we solve the stationary heat-flux equation analytically. We demonstrate the overheating hysteresis in the large-current or voltage regimes. In addition we consider the influence of a substrate on the system which acts as a heat sink. We show that nanodot chains can be used as highly sensitive thermometers over a broad range of temperatures. C1 [Glatz, A.; Chtchelkatchev, N. M.; Vinokur, V.

The behavior of these structures under uniaxial tensile strain was investigated. The electronic origin of the soft phonon modes and the mechanical properties of niobium nitrides are discussed.

The undoped ZnO nanoparticles showed zero or negligible magnetization without any dependence on the nanoparticle size. However, chemically synthesized Zn(1-x)Fe(x)O nanoparticles showed clear ferromagnetism, varying systematically with Fe concentration. Furthermore, the magnetic properties of Zn(1-x)Fe(x)O nanoparticles showed strong dependence on the reaction media used to prepare the samples. The zeta potentials of the Zn(1-x)Fe(x)O nanoparticles prepared using different reaction media were significantly different, indicating strong differences in the surface structure.

TI Magnetically induced electric polarization in an organometallic magnet SO PHYSICAL REVIEW B LA English DT Article ID FERROELECTRICITY; MULTIFERROICS AB The coupling between magnetic order and ferroelectricity has been under intense investigation in a wide range of transition-metal oxides. The most direct coupling is obtained in so-called magnetically induced multiferroics where ferroelectricity arises directly from magnetic order that breaks spatial inversion symmetry. However, it has been difficult to find nonoxide-based materials in which these effects occur. Here we present a study of copper dimethyl sulfoxide dichloride (CDC), an organometallic quantum magnet containing S = 1/2 Cu spins, in which electric polarization arises from noncollinear magnetic order. We show that the electric polarization can be switched in a stunning hysteretic fashion. Because the magnetic order in CDC is mediated by large organic molecules, our study shows that magnetoelectric interactions can exist in this important class of materials, opening the road to designing magnetoelectrics and multiferroics using large molecules as building blocks. Further, we demonstrate that CDC undergoes a magnetoelectric quantum phase transition where both ferroelectric and magnetic order emerge simultaneously as a function of magnetic field at very low temperatures.

The particle-hole and particle-particle channels are optimized simultaneously, and the experimental data set includes both spherical and deformed nuclei. The new model-based, derivative-free optimization algorithm used in this work has been found to be significantly better than standard optimization methods in terms of reliability, speed, accuracy, and precision. The resulting parameter set UNEDF0 results in good agreement with experimental masses, radii, and deformations and seems to be free of finite-size instabilities. An estimate of the reliability of the obtained parameterization is given, based on standard statistical methods. We discuss new physics insights offered by the advanced covariance analysis.

This is useful for constraining relations between galaxies and the dark matter, such as the galaxy bias, especially in situations where sampling variance errors can be eliminated. In this paper we extend this study with the goal of finding the optimal mass-dependent halo weighting. We use N-body simulations to perform a general analysis of halo stochasticity and its dependence on halo mass. We investigate the stochasticity matrix, defined as C-ij <(delta(i) -b(i)delta(m) )(delta(j) -b(j)delta(m))>, where delta(m) is the dark matter overdensity in Fourier space, delta(i) the halo overdensity of the i-th halo mass bin, and b(i) the corresponding halo bias. In contrast to the Poisson model predictions we detect nonvanishing correlations between different mass bins. We also find the diagonal terms to be sub-Poissonian for the highest-mass halos. The diagonalization of this matrix results in one large and one low eigenvalue, with the remaining eigenvalues close to the Poisson prediction 1/(n) over bar, where (n) over bar is the mean halo number density. The eigenmode with the lowest eigenvalue contains most of the information and the corresponding eigenvector provides an optimal weighting function to minimize the stochasticity between halos and dark matter. We find this optimal weighting function to match linear mass weighting at high masses, while at the low-mass end the weights approach a constant whose value depends on the low-mass cut in the halo mass function. This weighting further suppresses the stochasticity as compared to the previously explored mass weighting. Finally, we employ the halo model to derive the stochasticity matrix and the scale-dependent bias from an analytical perspective. It is remarkably successful in reproducing our numerical results and predicts that the stochasticity between halos and the dark matter can be reduced further when going to halo masses lower than we can resolve in current simulations.

We again take seriously the several 2-3 sigma anomalies seen in B, B-s decays and interpret them in the context of this simple extension of the SM. SM4 is also of course of considerable interest for its potential relevance to dynamical electroweak symmetry breaking and to baryogenesis. Using experimental information from processes such as B -> X-s gamma, B-d and B-s mixings, indirect CP-violation from K-L -> pi pi etc. along with oblique corrections, we constrain the relevant parameter space of the SM4, and find m(t') of about 400-600 GeV with a mixing angle vertical bar V-t'b(*) V-t's vertical bar in the range of about 0:05-1:4 x 10(-2) and with an appreciable CP-odd associated phase, are favored by the current data. Given the unique role of the CP asymmetry in B-s -> psi phi due to its gold-plated nature, correlation of that with many other interesting observables, including the semileptonic asymmetry (A(SL)) are studied in SM4. We also identify several processes, such as B -> X-s nu(nu) over bar, K-L -> pi(0)nu(nu) over bar etc., that are significantly different in SM4 from the SM. Experimentally the very distinctive process Bs -> mu(+)mu(-) is also discussed; the branching ratio can be larger or smaller than in SM, (3.2 -> 4.2) x 10(-9), by a factor of O(3).

TI Design of polymer nanocomposites in solution by polymer functionalization SO PHYSICAL REVIEW E LA English DT Article ID COPOLYMER-NANOPARTICLE COMPOSITES; BLOCK-COPOLYMER; MOLECULAR-DYNAMICS; TRIBLOCK COPOLYMERS; STRONG SEGREGATION; CUBIC-CRYSTALS; AGGREGATION; SIMULATION; MIXTURES; DIBLOCK AB Polymer nanocomposites, materials combining polymers and inorganic components such as nanosized crystallites or nanoparticles have attracted significant attention in recent years. A successful strategy for designing polymer nanocomposites is polymer functionalization via attaching functional groups with specific affinity for the inorganic component. In this paper, a systematic investigation by molecular dynamics of polymer functionalization for design of composites combining nanosize crystallites with multiblock polymers in solution is presented. It is shown that functionalization is an example of active self-assembly, where the resulting polymer nanocomposite exhibits a different type of order than the original pure polymer system (without inorganic components). Optimal polymer architectures and concentrations are identified appropriate for different applications, alongside an in-depth analysis on the origin and stability of the resulting phases as well as its experimental implications.

This instrument allows characterization of structural degrees of freedom to temperatures as low as 4.4 K, and in applied magnetic fields as large as 30 T. We show that Tb2Ti2O7 manifests intriguing structural effects under the application of magnetic fields, including strongly anisotropic giant magnetostriction, a restoration of perfect pyrochlore symmetry in low magnetic fields, and ultimately a structural phase transition in high magnetic fields.

TI In-Plane Resistivity Anisotropy in an Underdoped Iron Arsenide Superconductor SO SCIENCE LA English DT Article ID STATE AB High-temperature superconductivity often emerges in the proximity of a symmetry-breaking ground state. For superconducting iron arsenides, in addition to the antiferromagnetic ground state, a small structural distortion breaks the crystal's C(4) rotational symmetry in the underdoped part of the phase diagram. We reveal that the representative iron arsenide Ba(Fe(1-x)Co(x))(2)As(2) develops a large electronic anisotropy at this transition via measurements of the in-plane resistivity of detwinned single crystals, with the resistivity along the shorter b axis rho(b) being greater than rho(a). The anisotropy reaches a maximum value of similar to 2 for compositions in the neighborhood of the beginning of the superconducting dome. For temperatures well above the structural transition, uniaxial stress induces a resistivity anisotropy, indicating a substantial nematic susceptibility.

It was found that in the n = 2 manifold the excitations could be interpreted as superpositions of atomic states, with excitations on the surface of the clusters being lower in energy than those in the bulk. For the n = 2 excited states with significant density on the interior of the cluster, mixing with the atomic n = 3 states resulted in lower excitation energies. For the n = 3 states the spatial extent of the excited-state density can be much larger than the size of the cluster, making analysis of the states more difficult and highly dependent on the intemuclear distance. Introducing disorder into the clusters results in some localization of the excited states, although highly delocalized states are always observed in these small clusters. In addition, experimental results for small clusters are interpreted in terms of these findings. C1 [Closser, Kristina D.; Head-Gordon, Martin] Univ Calif Berkeley, Dept Chem, Berkeley, CA 94720 USA.

Alan TI Precipitation-generated oscillations in open cellular cloud fields SO NATURE LA English DT Article ID COMPLEX NETWORKS; OPEN CELLS; CONVECTION; MESOSCALE; STRATOCUMULUS; ORGANIZATION; DRIZZLE; MODEL; MICROPHYSICS; PATTERNS AB Cloud fields adopt many different patterns that can have a profound effect on the amount of sunlight reflected back to space, with important implications for the Earth's climate. These cloud patterns can be observed in satellite images of the Earth and often exhibit distinct cell-like structures associated with organized convection at scales of tens of kilometres(1-3). Recent evidence has shown that atmospheric aerosol particles-through their influence on precipitation formation-help to determine whether cloud fields take on closed (more reflective) or open (less reflective) cellular patterns(4,5). The physical mechanisms controlling the formation and evolution of these cells, however, are still poorly understood(6), limiting our ability to simulate realistically the effects of clouds on global reflectance. Here we use satellite imagery and numerical models to show how precipitating clouds produce an open cellular cloud pattern that oscillates between different, weakly stable states. The oscillations are a result of precipitation causing downward motion and outflow from clouds that were previously positively buoyant. The evaporating precipitation drives air down to the Earth's surface, where it diverges and collides with the outflows of neighbouring precipitating cells. These colliding outflows form surface convergence zones and new cloud formation. In turn, the newly formed clouds produce precipitation and new colliding outflow patterns that are displaced from the previous ones. As successive cycles of this kind unfold, convergence zones alternate with divergence zones and new cloud patterns emerge to replace old ones. The result is an oscillating, self-organized system with a characteristic cell size and precipitation frequency. C1 [Feingold, Graham; Brewer, Wm.

A quantum-mechanical description of the cascading process that occurs after photoexcitation is presented. The conditions for ultrafast cascading are given, which relate the energy difference between the levels in the cascading process to the electron-phonon self energy. These limitations aid in the determination of the cascade path. For Fe(2+) spin-crossover complexes, this leads to the conclusion that the ultrafast decay primarily occurs in the manifold of antibonding metal-to-ligand charge-transfer states. We also give an interpretation why some intermediate states are bypassed. C1 [Chang, Jun; Fedro, A. J.; van Veenendaal, Michel] No Illinois Univ, Dept Phys, De Kalb, IL 60115 USA.

We find that the bulklike optical response in the noble-metal nanoparticles is determined more strongly by the electronic d character of the valence electrons than the atomic coordination or size of the nanoparticles. The importance of Coulomb and exchange-correlation interactions to model optical responses is also discussed. C1 [Idrobo, J. C.; Pantelides, S.

There are three distinct types of penguin contributions: (i) b -> sq (q) over bar -> s eta(q), (ii) b -> ss (s) over bar -> s eta s, and (iii) b -> sq (q) over bar -> q (K) over bar (h), where eta(q) = (u (u) over bar + d (d) over bar)/root 2 and eta(s) = s (s) over bar. B -> K(*)eta(') decays are dominated by type-II and type-III penguin contributions. The interference, constructive for K eta' and K*eta and destructive for K eta and K*eta', between type-II and type-III diagrams explains the pattern of Gamma(B -> K eta') >> Gamma(B -> K eta) and Gamma(B -> K*eta') << Gamma(B -> K*eta). Within QCDF, the observed large rate of the K eta' mode can be naturally explained without invoking flavor-singlet contributions or something exotic. The decay pattern for B -> K-0*(1430)eta(') decays depends on whether the scalar meson K-0*(1430) is an excited state of kappa or a lowest-lying P-wave q (q) over bar state. Hence, the experimental measurements of B -> K-0*(1430)eta(') can be used to explore the quark structure of K-0*(1430). If K-0*(1430) is a low-lying q (q) over bar bound state, we find that K-0*eta has a rate slightly larger than K-0*eta' owing to the fact that the eta - eta' mixing angle in the eta(q), eta(s) flavor basis is less than 45 degrees, in agreement with experiment. The type-III penguin diagram does not contribute to B -> K-2*eta((')) under the factorization hypothesis and the type-II diagram dominates. The ratio Gamma(B -> K-2*eta')/Gamma(B -> K-2*eta) is expected to be of order 2.5 as a consequence of (i) vertical bar f(eta')(s)vertical bar > vertical bar f(eta)(s)vertical bar and (ii) a destructive (constructive) interference between type-I and type-II penguin diagrams for K-2*eta (K-2*eta'). However, the predicted rates of B -> K-2*eta((')) in naive factorization are too small by 1 order of magnitude and this issue remains to be resolved. There are two K-(*)eta((')) modes in which direct CP asymmetries have been measured with significance around 4 sigma: A(CP)(K-eta) = -0.37 +/- 0.09 and A(CP)((K) over bar*(0)eta) = 0.19 +/- 0.05. In QCDF, power corrections from penguin annihilation which are needed to resolve CP puzzles in K- pi(+) and pi(+) pi(-) modes will flip A(CP)(K-eta) into a wrong sign. We show that soft corrections to the color-suppressed tree amplitude a(2) in conjunction with the charm content of the eta will finally lead to A(CP)(K-eta) = 0.15(-0.28)(+0.19). Likewise, this power correction is needed to improve the prediction for A(CP)((K) over bar*(0)eta). C1 [Cheng, Hai-Yang] Acad Sinica, Inst Phys, Taipei 115, Taiwan.

With careful operator construction, the combination of these techniques is used to identify the continuum spin of extracted states reliably, overcoming the reduced rotational symmetry of the cubic lattice. Excited states, states with exotic quantum numbers (0(+-), 1(-+) and 2(+-)), and states of high spin are resolved, including, for the first time in a lattice QCD calculation, spin-four states. The determinations of the spectrum of isovector mesons and kaons are performed on dynamical lattices with two volumes and with pion masses down to similar to 400 MeV, with statistical precision typically at or below 1% even for highly excited states.

The larger spheres will tend to locate next to the substrate because the overall system entropy loss per unit area is less. In the present study we determine the role of attraction between the small particles and the wall to displace the larger particles. Both fluids density-functional theory and discontinuous molecular dynamics simulations demonstrate that at a certain attractive potential, which is on the order of the thermal energy, the large particles can indeed be dislodged from the surface layer so the small particles are now the major surface component. Exploration of a range of parameters, including relative sphere size and concentration, as well as attractions between the small spheres in the bulk, shows that the phenomenon is quite robust.

CA ALICE Collaboration TI Midrapidity Antiproton-to-Proton Ratio in pp Collisons root s=0.9 and 7 TeV Measured by the ALICE Experiment SO PHYSICAL REVIEW LETTERS LA English DT Article ID TOTAL CROSS-SECTIONS; ANTINUCLEON-NUCLEON; STRING MODEL; SCATTERING; ENERGIES; COLLISIONS; PHYSICS AB The ratio of the yields of antiprotons to protons in pp collisions has been measured by the ALICE experiment at root s = 0.9 and 7 TeV during the initial running periods of the Large Hadron Collider. The measurement covers the transverse momentum interval 0.45 < p(t) < 1.05 GeV/c and rapidity vertical bar y vertical bar < 0.5. The ratio is measured to be R-vertical bar y vertical bar<0.5 = 0.957 +/- 0.006(stat) +/- 0.0014(syst) at 0.9 Tev and R-vertical bar y vertical bar<0.5 = 0.991 +/- 0.005 +/- 0.014(syst) at 7 TeV and it is independent of both rapidity and transverse momentum. The results are consistent with the conventional model of baryon-number transport and set stringent limits on any additional contributions to baryon-number transfer over very large rapidity intervals in pp collisions.

Petawatt laser produced K-alpha radiation scatters on boron targets compressed by a 10 ns-long 400 J laser pulse. In the vicinity of the Fermi momentum, the scattering spectra show dispersionless, collisionally damped plasmons, indicating a strongly coupled electron liquid. These observations agree with calculations that include the Born-Mermin approximation to account for electron-ion collisional damping and local field corrections reflecting electron-electron correlations.

The polarization-transfer coefficients are found to differ from those of the H-1((e) over right arrow, e '(p) over right arrow) reaction, contradicting a relativistic distorted-wave approximation and favoring either the inclusion of medium-modified proton form factors predicted by the quark-meson coupling model or a spin-dependent charge-exchange final-state interaction. For the first time, the polarization-transfer ratio is studied as a function of the virtuality of the proton. C1 [Paolone, M.; Malace, S.

This approximation, in which many-body induced polarization effects are included in an average way, is expected to be satisfactory for a wide range of systems, but less accurate for processes involving the transfer and partition of ions among heterogeneous environments. The limitations of these potential energy functions are perhaps most obvious in studies of ion permeation through membrane channels. In many cases, the pore is so narrow that the permeating ion must shed most of its surrounding water molecules and the large energetic loss due to dehydration must be compensated by coordination with protein atoms. Interactions of cations with protein backbone carbonyl oxygens, in particular, play a critical role in several important biological channels. As a first step toward meeting the challenge of developing an accurate explicit accounting for induced polarization effects, the present work combines experiments and computation to characterize the interactions of alkali and halide ions with N-methylacetamide chosen to represent the peptide bond. From solubility measurements, we extract the solvation free energies of KCl and NaCl in liquid N-methylacetamide. Polarizable models based on the Drude oscillator are then developed and compared with available experimental and ab initio data. The good agreement for a range of structural and thermodynamic properties in the gas and condensed phases suggests that the polarizable models provide an accurate representation of ion amide interactions in biological systems.

TI A 33-GHz Very Small Array survey of the Galactic plane from l=27 degrees to 46 degrees SO MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY LA English DT Article DE techniques: interferometric; HII regions; Galaxy: general; radio continuum: ISM ID ANOMALOUS MICROWAVE EMISSION; RADIO-CONTINUUM SURVEY; BACKGROUND POWER SPECTRUM; ELECTRIC-DIPOLE EMISSION; ANISOTROPY-PROBE; SPINNING DUST; EXCESS EMISSION; HII-REGIONS; SKY MAPS; 31 GHZ AB The Very Small Array (VSA) has been used to survey the l similar to 27 degrees to similar to 46 degrees, vertical bar b vertical bar < 4 degrees region of the Galactic plane at a resolution of 13 arcmin. This l-range covers a section through the Local, Sagittarius and the Cetus spiral arms. The survey consists of 44 pointings of the VSA, each with an rms sensitivity of similar to 90 mJy beam(-1). These data are combined in a mosaic to produce a map of the area. The majority of the sources within the map are HII regions. The main aim of the programme was to investigate the anomalous radio emission from the warm dust in individual HII regions of the survey. This programme required making a spectrum extending from GHz frequencies to the far-infrared (FIR) IRAS frequencies for each of nine strong sources selected to lie in unconfused areas. It was necessary to process each of the frequency maps with the same u, v coverage as was used for the VSA 33 GHz observations. The additional radio data were at 1.4, 2.7, 4.85, 8.35, 10.55, 14.35 and 94 GHz in addition to the 100, 60, 25 and 12 mu m IRAS bands. From each spectrum the free-free, thermal dust and anomalous dust emission were determined for each HII region. The mean ratio of 33 GHz anomalous flux density to FIR 100 mu m flux density for the nine selected HII regions was Delta S(33 GHz)/S(100 mu m) = 1.10 +/- 0.21 x 10(-4). When combined with six HII regions previously observed with the VSA and the Cosmic Background Imager, the anomalous emission from warm dust in HII regions is detected with a 33 GHz emissivity of 4.65 +/- 0.40 mu K (MJy sr(-1))(-1) (11.5 sigma). This level of anomalous emission is 0.3 to 0.5 of that detected in cool dust clouds. A radio spectrum of the HII region anomalous emission covering GHz frequencies is constructed. It has the shape expected for spinning dust composed of very small grains. The anomalous radio emission in HII regions is on average 41 +/- 10 per cent of the radio continuum at 33 GHz. Another result is that the excess (i.e. non-free-free) emission from HII regions at 94 GHz correlates strongly with the 100 mu m emission; it is also inversely correlated with the dust temperature. Both these latter results are as expected for very large grain dust emission. The anomalous emission on the other hand is expected to originate in very small spinning grains and correlates more closely with the 25 mu m emission.

TI Simulation of rare isotope release from ISOL target SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Target-vapor transport system; Rare isotope; Diffusion release; Effusive-flow; Radioactive decay ID SYSTEMS AB Releases of short-lived species from ISOL targets are simulated with computer codes. Analytic solutions to the diffusion equation are compared with those obtained from a finite-difference code for radioactive isotope diffusion release from simple geometry targets. The Monte Carlo technique as a practical means for vapor transport system design is demonstrated by simulating the effusive-flow of neutral particles through complex target-vapor transport systems. Particle release curves involving decay losses in both diffusion and effusive-flow are computed; and a numerical procedure is proposed to measure the diffusion coefficients and the characteristic effusion times of rare isotopes in target-ion source systems.

TI Effects of external magnetic fields on the operation of high-gradient accelerating structures SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Accelerator physics; High-gradient accelerating structures; RF breakdown; Muon collider ID BREAKDOWN AB Field emission in an rf cavity in the presence of external magnetic fields is examined. We show that emitted electrons from a sharp protrusion are focused by the magnetic field into small spots at another location in the cavity where they heat its surface. Scaling laws are established for the beam's induced heat in terms of macroscopic quantities such as magnetic field, accelerating gradient and spot dimensions. We find that when the magnetic field is of the order of a Tesla, the induced thermal stresses by the pulsed electron flux exceed the elastic limit and the surface becomes prone to cycling fatigue. The implication of these findings on the observed surface damage and magnetic-field-depended breakdown of an 805 MHz cavity is addressed. (C) 2010 Elsevier B.V. All rights reserved.

It combines a surface array to measure secondary particles at ground level together with a fluorescence detector to measure the development of air showers in the atmosphere above the array. The fluorescence detector comprises 24 large telescopes specialized for measuring the nitrogen fluorescence caused by charged particles of cosmic ray air showers. In this paper we describe the components of the fluorescence detector including its optical system, the design of the camera, the electronics, and the systems for relative and absolute calibration. We also discuss the operation and the monitoring of the detector. Finally, we evaluate the detector performance and precision of shower reconstructions. (C) 2010 Elsevier B.V All rights reserved.

TI Praseodymium activation detector for measuring bursts of 14 MeV neutrons SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Neutron detection; Activation detector; (141)Pr; Dense plasma focus; Sum-peak ID DENSE-PLASMA FOCUS; CALIBRATION AB A new, accurate, neutron activation detection scheme for measuring pulsed neutrons has been designed and tested. The detection system is sensitive to neutrons with energies above 10 MeV; importantly, it is insensitive to gamma radiation < 10 MeV and to lower-energy (e.g., fission and thermal) neutrons. It is based upon the use of (141)Pr, an element that has a single, naturally occurring isotope, a significant n,2n cross-section, and decays by positron emission that result in two coincident 511 keV photons. Neutron fiuences are thus inferred by relating measured reaction product decay activity to fluence. Specific sample activity is measured using the sum-peak method to count gamma-ray coincidences from the annihilation of the positron decay products. The system was tested using 14 and 2.45 MeV neutron bursts produced by NSTec Dense Plasma Focus Laboratory fusion sources. Lead, copper, beryllium, and silver activation detectors were compared. The detection method allows measurement of 14 MeV neutron yield with a total error of approximate to 18%. (C) 2010 Elsevier B.V. All rights reserved. C1 [Meehan, Tim; Hagen, E.

TI A liquid parahydrogen target for the measurement of a parity-violating gamma asymmetry in (n)over-right-arrow + p -> d plus gamma SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article DE Liquid parahydrogen; Parity-violation; gamma-asymmetry; Neutron depolarization; Bubble suppression; Hydrogen safety; Cryorefrigerator; Ortho-to-para converters ID HYDROGEN TARGET; CIRCULAR-POLARIZATION; BUBBLE CHAMBERS; ELECTRON; TRACKS; BEAM; THIN AB A 161 liquid parahydrogen target has been developed for a measurement of the parity-violating gamma-asymmetry in the capture of polarized cold neutrons on protons in the (n) over right arrow + p -> d + gamma reaction by the NPDGamma collaboration. The target system was carefully designed to meet the stringent requirements on systematic effects for the experiment and also to satisfy hydrogen safety requirements. The target was designed to preserve the neutron polarization during neutron scattering on liquid hydrogen (LH(2)), optimize the statistical sensitivity to the (n) over right arrow + p -> d + gamma reaction, minimize backgrounds coming from neutron interaction with the beam windows of the target cryostat, minimize LH(2) density fluctuations which can introduce extra noise in the gamma asymmetry signal, and control systematic effects. The target incorporates two mechanical refrigerators, two ortho-para convertors, an aluminum cryostat, an aluminum target vessel shielded with (6)Li-rich plastic, a hydrogen fill/vent line with a passive recirculation loop to establish and maintain the equilibrium ortho-para ratio, a hydrogen relief system coupled to a vent stack, a gas handling system, and an alarm and interlock system. Low Z, nonmagnetic materials were used for the target vessel and cryostat. Pressure and temperature sensors monitored the thermodynamic state of the target. Relative neutron transmission measurements were used to monitor the parahydrogen fraction of the target. The target was thoroughly tested and successfully operated during the first phase of the NPDGamma experiment conducted at the FP12 beam line at Los Alamos Neutron Science Center (LANSCE). An upgraded version of the target system will be used in the next stage of the experiment, which will be performed at the Fundamental Neutron Physics Beam (FnPB) line of the Spallation Neutron Source at Oak Ridge National Laboratory.

The genitalia can be used to distinguish the sex and to identify the insects when the external structure appears identical. For this purpose, a destructive dissecting microscopy procedure is usually employed. In this paper, phase contrast X-ray imaging (radiography and tomography) is employed to investigate the internal structure (genitalia) of two entire species of weevils that presents very similar external structures (Sitophilus oryzae and Sitophilus zeamais). The detection of features, which looks like the genital structure, shows that such non-destructive technique could be used as an alternative method for identification of insects. This method is especially useful in examining the internal features of precious species from museum collections, as already described in the recent literature. (C) 2010 Elsevier B.V.

R. Lin, Jie TI Spin zeros and the origin of Fermi-surface reconstruction in the cuprates SO PHYSICAL REVIEW B LA English DT Article ID T-C SUPERCONDUCTOR; QUANTUM OSCILLATIONS AB Two recent quantum oscillation studies find contradictory results concerning the existence of spin zeros-zeros of the oscillatory signal induced by Zeeman splitting of the Landau levels. We discuss these experiments in light of calculations of the oscillations assuming a spin-density wave state. We find that the lack of spin zeros reported in one of the experiments is consistent with either hole or electron pockets in such a state, if the staggered moment is perpendicular to the external field. An analysis for field directions near the planes might be able to differentiate between the two. On the other hand, if spin zeros exist as reported in the other experiment, then the staggered moment would have to have a substantial longitudinal component. We suggest several experiments to test whether this is indeed the case. C1 [Norman, M. R.; Lin, Jie] Argonne Natl Lab, Div Mat Sci, Argonne, IL 60439 USA.

CA STAR Collaboration TI Balance functions from Au+Au, d+Au, and p+p collisions at root s(NN)=200 GeV SO PHYSICAL REVIEW C LA English DT Article ID HEAVY-ION COLLISIONS; AU-AU COLLISIONS; TIME PROJECTION CHAMBER; BY-EVENT FLUCTUATIONS; QUARK-GLUON PLASMA; TRANSVERSE-MOMENTUM; MEAN-P(T) FLUCTUATIONS; MODEL; HADRONIZATION; SIGNATURES AB Balance functions have been measured for charged-particle pairs, identified charged-pion pairs, and identified charged-kaon pairs in Au + Au, d + Au, and p + p collisions at root s(NN) = 200 GeV at the Relativistic Heavy Ion Collider using the STAR detector. These balance functions are presented in terms of relative pseudorapidity, Delta eta, relative rapidity, Delta y, relative azimuthal angle, Delta phi, and invariant relative momentum, q(inv). For charged-particle pairs, the width of the balance function in terms of Delta eta scales smoothly with the number of participating nucleons, while HIJING and UrQMD model calculations show no dependence on centrality or system size. For charged-particle and charged-pion pairs, the balance functions widths in terms of Delta eta and Delta y are narrower in central Au + Au collisions than in peripheral collisions. The width for central collisions is consistent with thermal blast-wave models where the balancing charges are highly correlated in coordinate space at breakup. This strong correlation might be explained by either delayed hadronization or limited diffusion during the reaction. Furthermore, the narrowing trend is consistent with the lower kinetic temperatures inherent to more central collisions. In contrast, the width of the balance function for charged-kaon pairs in terms of Delta y shows little centrality dependence, which may signal a different production mechanism for kaons. The widths of the balance functions for charged pions and kaons in terms of q(inv) narrow in central collisions compared to peripheral collisions, which may be driven by the change in the kinetic temperature.

We show that this large class of models posses a conformal window describing a nontrivial flow between two fixed points of the renormalization group and reveal the presence of a resonance which we associate to the remnant of a dilaton pole. As the conformal window shrinks to zero measure, the theory undergoes a conformal phase transition separating a symmetric from a nonsymmetric phase. The recently conjectured strongly coupled branch of nonsupersymmetric, non-Abelian gauge theories with a large number of flavors is analyzed in light of these results, and a model for the strong branch is proposed. Some phenomenological implications in the context of unparticle physics are also emphasized. C1 Los Alamos Natl Lab, Theoret Div T2, Los Alamos, NM 87545 USA.

Full characterization (quantum tomography) of imperfect pulses presents a bootstrap problem: tomography requires initial states of a qubit which cannot be prepared without perfect pulses. We present a protocol for pulse error analysis, specifically tailored for a wide range of the single solid-state electron spins. Using a single electron spin of a nitrogen-vacancy center in diamond, we experimentally verify the correctness of the protocol, and demonstrate its usefulness for quantum control tasks.

We used cryo-electron microscopy to investigate the molecular basis for these critical mechanical properties. High-quality structural maps were used to build pseudoatomic models of microtubules containing 11-16 protofilaments, representing a wide range of lateral curvature. Protofilaments in all these microtubules were connected primarily via interprotofilament interactions between the M loops, and the H1'-S2 and H2-S3 loops. We postulate that the tolerance of the loop-loop interactions to lateral deformation provides the capacity for high-curvature bending without breaking. On the other hand, the local molecular architecture that surrounds these connecting loops contributes to the overall rigidity. Interprotofilament interactions in the seam region are similar to those in the normal helical regions, suggesting that the existence of the seam does not significantly affect the mechanical properties of microtubules.

The proposed apparatus incorporates currently common optical velocimetry techniques used in shock physics, with interferometric techniques developed to self-stabilize and passively balance interferometers in quantum cryptography. The result is a robust telecom-fiber-based velocimetry system insensitive to modal and frequency dispersion that should work well in the presence of decoherent scattering processes, such as from ejecta clouds and shocked surfaces.

The survey is designed to detect rare, very bright transients as well as to verify the capabilities of the ATA to form large mosaics. The combined image using data from all 12 ATATS epochs has rms noise sigma = 3.94 mJy beam(-1) and dynamic range 180, with a circular beam of 150 '' FWHM. It contains 4408 sources to a limiting sensitivity of 5 sigma = 20 mJy beam(-1). We compare the catalog generated from this 12 epoch combined image to the NRAO VLA Sky Survey (NVSS), a legacy survey at the same frequency, and find that we can measure source positions to better than similar to 20 ''. For sources above the ATATS completeness limit, the median flux density is 97% of the median value for matched NVSS sources, indicative of an accurate overall flux calibration. We examine the effects of source confusion due to the effects of differing resolution between ATATS and NVSS on our ability to compare flux densities. We detect no transients at flux densities greater than 40 mJy in comparison with NVSS and place a 2 sigma upper limit of 0.004 deg(-2) on the transient rate for such sources. These results suggest that the greater than or similar to 1 Jy transients reported by Matsumara et al. may not be true transients, but rather variable sources at their flux density threshold.

TI EXTRAGALACTIC MILLIMETER-WAVE SOURCES IN SOUTH POLE TELESCOPE SURVEY DATA: SOURCE COUNTS, CATALOG, AND STATISTICS FOR AN 87 SQUARE-DEGREE FIELD SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: high-redshift; submillimeter: galaxies; surveys ID SPECTRUM RADIO-SOURCES; STAR-FORMING GALAXIES; SCUBA SUPER-MAP; GOODS-N FIELD; SUBMILLIMETER-SELECTED GALAXIES; COMPACT STEEP-SPECTRUM; 1200-MU-M MAMBO SURVEY; ALL-SKY SURVEY; 1.1 MM SURVEY; NUMBER COUNTS AB We report the results of an 87 deg(2) point-source survey centered at R. A. 5(h)30(m), decl. -55 degrees taken with the South Pole Telescope at 1.4 and 2.0 mm wavelengths with arcminute resolution and milli-Jansky depth. Based on the ratio of flux in the two bands, we separate the detected sources into two populations, one consistent with synchrotron emission from active galactic nuclei and the other consistent with thermal emission from dust. We present source counts for each population from 11 to 640 mJy at 1.4 mm and from 4.4 to 800mJy at 2.0 mm. The 2.0 mm counts are dominated by synchrotron-dominated sources across our reported flux range; the 1.4 mm counts are dominated by synchrotron-dominated sources above similar to 15 mJy and by dust-dominated sources below that flux level. We detect 141 synchrotron-dominated sources and 47 dust-dominated sources at signal-to-noise ratio S/N > 4.5 in at least one band. All of the most significantly detected members of the synchrotron-dominated population are associated with sources in previously published radio catalogs. Some of the dust-dominated sources are associated with nearby (z << 1) galaxies whose dust emission is also detected by the Infrared Astronomy Satellite. However, most of the bright, dust-dominated sources have no counterparts in any existing catalogs. We argue that these sources represent the rarest and brightestmembers of the population commonly referred to as submillimeter galaxies (SMGs). Because these sources are selected at longer wavelengths than in typical SMG surveys, they are expected to have a higher mean redshift distribution and may provide a new window on galaxy formation in the early universe.

TI DISCOVERY OF VERY HIGH ENERGY gamma-RAY EMISSION FROM THE SNR G54.1+0.3 SO ASTROPHYSICAL JOURNAL LETTERS LA English DT Article DE gamma rays: general; ISM: supernova remnants; pulsars: individual (J1930+1852, J1928+1746) ID PULSAR WIND NEBULAE; SUPERNOVA REMNANT G54.1+0.3; CRAB-NEBULA; VERITAS; TELESCOPE; ASTRONOMY; G0.9+0.1; CATALOG; SEARCH AB We report the discovery of very high energy (VHE) gamma-ray emission from the direction of the SNR G54.1+ 0.3 using the VERITAS ground-based gamma-ray observatory. The TeV signal has an overall significance of 6.8s and appears pointlike given the resolution of the instrument. The integral flux above 1 TeV is 2.5% of the Crab Nebula flux and significant emission is measured between 250 GeV and 4 TeV, well described by a power-law energy spectrum dN/dE similar to E(-Gamma) with a photon index Gamma = 2.39 +/- 0.23(stat) +/- 0.30sys. We find no evidence of time variability among observations spanning almost two years. Based on the location, the morphology, the measured spectrum, the lack of variability, and a comparison with similar systems previously detected in the TeV band, the most likely counterpart of this new VHE gamma-ray source is the pulsar wind nebula (PWN) in the SNR G54.1+0.3. The measured X-ray to VHE gamma-ray luminosity ratio is the lowest among all the nebulae supposedly driven by young rotation-powered pulsars, which could indicate a particle-dominated PWN.

TI BLACK HOLE SPIN-ORBIT MISALIGNMENT IN GALACTIC X-RAY BINARIES SO ASTROPHYSICAL JOURNAL LETTERS LA English DT Article DE binaries: close; Galaxy: stellar content; stars: evolution; X-rays: binaries ID COMPACT OBJECT FORMATION; GRO J1655-40; ACCRETION DISCS; MASS; ALIGNMENT; KICKS; GRO-J1655-40; CONTINUUM; DISKS AB In black hole (BH) X-ray binaries (XRBs), a misalignment between the spin axis of the BH and the orbital angular momentum can occur during the supernova explosion that forms the compact object. In this Letter, we present population synthesis (PS) models of Galactic BH XRBs and study the probability density function of the misalignment angle and its dependence on our model parameters. In our modeling, we also take into account the evolution of the misalignment angle due to accretion of material onto the BH during the XRB phase. The major factor that sets the misalignment angle for XRBs is the natal kick that the BH may receive at its formation. However, large kicks tend to disrupt binaries, while small kicks allow the formation of XRBs and naturally select systems with small misalignment angles. Our calculations predict that the majority (> 67%) of Galactic field BH XRBs have rather small (less than or similar to 10 degrees) misalignment angles, while some systems may reach misalignment angles as high as similar to 90 degrees. and even higher. These results are robust among all PS models. The assumption of small misalignment angles is extensively used to observationally estimate BH spin magnitudes, and for the first time we are able to confirm this assumption using detailed PS calculations.

Density functional theoretical (DFT) calculations were carried out simultaneously for comparison. The results confirm a pressure induced phase transition from the tetragonal I4mm phase to a high pressure orthorhombic Cmc21 phase around 1.22 GPa. Further increase of pressure above 8 GPa, we observed a second structural transition from Cmc21 to a tri-clinic P1 phase which are reversible with small hysteresis. The transition pressures and the bulk modulus obtained experimentally are in good agreement with theory. (C) 2010 Elsevier B.V. All rights reserved.

The property addressed here is structural off-centering, the molecular basis for the existence of switchable dipoles in polar materials, and whether it is turned off when particles become very small. This is probed using neutron scattering in a sample of free-standing, capped nanoparticles of the canonical perovskite ferroelectric, BaTiO3, with sizes near 5 nm. The structure, analyzed in reciprocal and real space, reveals the atomic correlations of the nanoparticle oxide and the capping benzyloxy ligand groups, and allows careful comparison with the structure of bulk BaTiO3. Even at these very small sizes, Ti is locally strongly off-centered, despite presenting cubic Bragg scattering.

The effect of electronic environment of the iron sites on the sound velocities were tracked in situ using synchrotron Mossbauer spectroscopy. We found the sound velocities of (Mg.16Fe.84)O to be much lower than those in other presumed mantle phases at similar conditions, most notably at very high pressures. Conservative estimates of the effect of temperature and dilution on aggregate sound velocities show that only a small amount of iron-rich (Mg,Fe)O can greatly reduce the average sound velocity of an assemblage. We propose that iron-rich (Mg,Fe)O be a source of ultra-low velocity zones. Other properties of this phase, such as enhanced density and dynamic stability, strongly support the presence of iron-rich (Mg,Fe)O in localized patches above the core-mantle boundary.

Patients and Methods The frequency of genetic alterations at 1p36 and PER3 gene copy number status were analyzed in 180 lymph node-negative breast cancers from patients who had received treatment with chemotherapy and/or tamoxifen. The expression levels of PER3 were also analyzed using published microarray profiles from > 400 breast cancer samples. Finally, the effect of loss of Per3 on tumor susceptibility was tested using two mouse models of breast cancer. Results Deletion of PER3 is directly related to tumor recurrence in patients with estrogen receptor (ER) positive breast cancers treated with tamoxifen. Low expression of PER3 mRNA is associated with poor prognosis, particularly in a subset of tumors that are ER positive, and either luminal A or ERBB2-positive tumors. Mice deficient in Per3 showed increased susceptibility to breast cancer induced by carcinogen treatment or by overexpression of Erbb2. Conclusion Disruption of PER3 function may serve as an indicator of probability of tumor recurrence in patients with ER-positive tumors. Further investigations of this pathway may reveal links between deregulation of sleep homeostasis and breast tumorigenesis. J Clin Oncol 28: 3770-3778.

TI Robust and accurate filtered spherical harmonics expansions for radiative transfer SO JOURNAL OF COMPUTATIONAL PHYSICS LA English DT Article DE Radiative transfer; Spherical harmonics method ID MONTE-CARLO METHOD; P-N EQUATIONS; RIEMANN SOLVERS; TRANSPORT; TIME; HYDRODYNAMICS; DIFFUSION; P-1 AB We present a novel application of filters to the spherical harmonics (P(N)) expansion for radiative transfer problems in the high-energy-density regime. The filter we use is based on non-oscillatory spherical splines and a filter strength chosen to (i) preserve the equilibrium diffusion limit and (ii) vanish as the expansion order tends to infinity. Our implementation is based on modified equations that are derived by applying the filter after every time step in a simple first-order time integration scheme. The method is readily applied to existing codes that solve the P(N) equations. Numerical results demonstrate that the solution to the filtered P(N) equations are (i) more robust and less oscillatory than standard P(N) solutions and (ii) more accurate than discrete ordinates solutions of comparable order. In particular, the filtered P(7) solution demonstrates comparable accuracy to an implicit Monte Carlo solution for a benchmark hohlraum problem in 2D Cartesian geometry. (C) 2010 Elsevier Inc.

TI An extension of implicit Monte Carlo diffusion: Multigroup and the difference formulation SO JOURNAL OF COMPUTATIONAL PHYSICS LA English DT Article DE IMD; Non-grey; Multigroup; The difference formulation ID RADIATIVE-TRANSFER SIMULATIONS; TRANSPORT-EQUATION; DISCRETIZATION; TIME AB Implicit Monte Carlo (IMC) and Implicit Monte Carlo Diffusion (IMD) are approaches to the numerical solution of the equations of radiative transfer. IMD was previously derived and numerically tested on grey, or frequency-integrated problems [1]. In this research, we extend Implicit Monte Carlo Diffusion (IMD) to account for frequency dependence, and we implement the difference formulation [2] as a source manipulation variance reduction technique. We derive the relevant probability distributions and present the frequency dependent IMD algorithm, with and without the difference formulation. The IMD code with and without the difference formulation was tested using both grey and frequency dependent benchmark problems. The Su and Olson semi-analytic Marshak wave benchmark was used to demonstrate the validity of the code for grey problems [3]. The Su and Olson semi-analytic picket fence benchmark was used for the frequency dependent problems [4]. The frequency dependent IMD algorithm reproduces the results of both Su and Olson benchmark problems. Frequency group refinement studies indicate that the computational cost of refining the group structure is likely less than that of group refinement in deterministic solutions of the radiation diffusion methods. Our results show that applying the difference formulation to the IMD algorithm can result in an overall increase in the figure of merit for frequency dependent problems. However, the creation of negatively weighted particles from the difference formulation can cause significant numerical instabilities in regions of the problem with sharp spatial gradients in the solution. An adaptive implementation of the difference formulation may be necessary to focus its use in regions that are at or near thermal equilibrium. (C) 2010 Elsevier Inc. All rights reserved.

These LO states coexist with a superfluid state having a smooth pairing potential. We suggest that the LO phase could be accessible experimentally by increasing the trap aspect ratio adiabatically. We show that the local asymmetry effects contained in the ASLDA do not support a deformed superfluid core predicted by previous Bogoliubov-de Gennes treatments. C1 [Pei, J.

TI Quantum Monte Carlo calculations of dihydrogen binding energetics on Ca cations: An assessment of errors in density functionals for weakly bonded systems SO PHYSICAL REVIEW B LA English DT Article ID ELECTRONIC-STRUCTURE; APPROXIMATION AB We investigate the binding of single and quadruple hydrogen molecules on a positively charged Ca ion. By comparing with benchmark quantum Monte Carlo (QMC) calculations we demonstrate wide variability in other more approximate electronic-structure methods including common density functionals. Single determinant QMC calculations find no binding at short range by approximately 0.1 eV for the quadruple hydrogen molecule case, for a fixed hydrogen bond length of 0.77 angstrom. Density-functional calculations using common functionals such a local density approximation and B3LYP differ substantially from the QMC binding curve. We show that use of full Hartree-Fock exchange and Perdew-Burke-Ernzerhof (PBE) correlation (HFX + PBEC) obtains close agreement with the QMC results, both qualitatively and quantitatively. These results both motivate the use and development of improved functionals and indicate that caution is required applying electronic-structure methods to weakly bound systems such as hydrogen-storage materials based on metal-ion-decorated nanostructures.

TI Fermi surface of Cr1-xVx across the quantum critical point SO PHYSICAL REVIEW B LA English DT Article ID DENSITY-WAVE ANTIFERROMAGNETISM; ANTI-FERROMAGNETIC CHROMIUM; PHASE-TRANSITIONS; MAGNETIC-FIELDS; Q-VECTOR; ALLOYS; INTERFERENCE; DEPENDENCE; BEHAVIOR; METAL AB We have measured de Haas-van Alphen oscillations of Cr1-xVx, 0 <= x <= 0.05, at high fields for samples on both sides of the quantum critical point at x(c)=0.035. For all samples we observe only those oscillations associated with a single small hole band with magnetic breakdown orbits of the reconstructed Fermi surface evident for x < x(c). The absence of oscillations from Fermi surface sheets most responsible for the spin density wave (SDW) in Cr for x > x(c) is further evidence for strong fluctuation scattering of these charge carriers well into the paramagnetic regime. We find no significant mass enhancement of the carriers in the single observed band at any x. An anomalous field dependence of the de Haas-van Alphen signal for our x=0.035 crystal at particular orientations of the magnetic field is identified as due to magnetic breakdown that we speculate results from a field-induced SDW transition at high fields.

TI Elastic and magnetic effects on the infrared phonon spectra of MnF2 SO PHYSICAL REVIEW B LA English DT Article ID TEMPERATURE-DEPENDENCE; TIO2 RUTILE; DIELECTRIC-CONSTANTS; ACTIVE-MODES; AB-INITIO; PRESSURE; FLUORIDE; FEF2; ZNF2; CRYSTALS AB We measured the temperature-dependent infrared reflectivity spectra of MnF2 between 4 and 600 K. We show that the phonon spectrum undergoes a clear renormalization at T-N. The ab initio calculation we performed on this compound accurately predicts the magnitude and the direction of the changes in the phonon parameters across the antiferromagnetic transition, showing that they are mainly induced by the magnetic order. In this material, we found that the dielectric constant is mostly from phonon origin. The large change in the lattice parameters with temperature seen by x-ray diffraction as well as the A(2u) phonon softening below T-N indicate that magnetic order induced distortions in MnF2 are compatible with the ferroelectric instabilities observed in TiO2, FeF2 and other rutile-type fluorides. This study also shows the anomalous temperature evolution of the lower energy E-u mode in the paramagnetic phase, which can be compared to that of the B-1g phonon seen by Raman spectroscopy in many isostructural materials. This was interpreted as being a precursor of a phase transition from rutile to CaCl2 structure which was observed under pressure in ZnF2. C1 [Schleck, R.; Nahas, Y.; Lobo, R. P. S.

This compound shows short-range incommensurate magnetic correlation with incommensurability delta=0.21, whereas a Fe-free compound shows no magnetic correlation. Resistivity shows an up turn at low temperature in the form of ln (1/T) and shows no superconductivity. We observe reduction in resistivity by applying magnetic fields (i.e., a negative magnetoresistive effect) at temperatures below the onset of short-range magnetic correlation. Application of magnetic fields also suppresses the Fe-induced incommensurate magnetic correlation. We compare and contrast these observations with two different models: (1) stripe order and (2) dilute magnetic moments in a metallic alloy with associated Kondo behavior. The latter picture appears to be more relevant to the present results. C1 [Wakimoto, Shuichi; Kakurai, Kazuhisa] Japan Atom Energy Agcy, Quantum Beam Sci Directorate, Tokai, Ibaraki 3191195, Japan.

TI d-d excitations in bilayer manganites probed by resonant inelastic x-ray scattering SO PHYSICAL REVIEW B LA English DT Article ID PEROVSKITE-TYPE MANGANITES; CHARGE; LA1.2SR1.8MN2O7 AB We report a high-resolution resonant inelastic x-ray scattering investigation of the bilayer manganites La(2-2x)Sr(1+2x)Mn(2)O(7) with x = 0.36 and 0.5. The momentum dependence along the crystallographic (110) direction for energy losses 1 eV <= Delta E <= 15 eV has been measured in detail with the data analysis focusing on the energy-loss region 1 eV <= Delta E <= 5 eV, which includes a strong peak located at Delta E approximate to 2 eV. We observe a clear dispersion of up to 0.5 eV in the measured q range, which is direct evidence of the nonlocal character of this excitation. Further, we found that the intensity in this low-energy region strongly depends on both the reduced wave vector q = (h, h, 0), h = 0.1-0.5, and temperature, i.e., different ordered phases. Results can be explained via an intersite d-d charge-transfer excitation, proposed for pseudocubic manganites, where the hopping rate is strongly increased (decreased) by ferromagnetic (antiferromagnetic) alignment of neighboring in-plane Mn ion core spins.

TI Topological electromotive force from domain-wall dynamics in a ferromagnet SO PHYSICAL REVIEW B LA English DT Article ID ELECTRIC-CURRENT; MAGNETIZATION DYNAMICS; SPIN-TRANSFER; BERRY-PHASE; MOTION; NANOWIRES; TORQUES; FILMS AB We formulate a local gauge-invariant theory for the electromotive force induced by domain-wall dynamics in a ferromagnet. We demonstrate that this emf generation is a real-space topological pumping effect. The integral of the emf over one pumping period is a quantized topological invariant which does not depend on the details of the domain-wall configuration nor on its detailed dynamics. Based on our theory, the full instantaneous electric potential distribution can be mapped out by standard electrostatic methods. We also provide further details on our recent experiments which confirmed the emf induced by domain-wall dynamics. C1 [Yang, Shengyuan A.; Beach, Geoffrey S.

TI Pressure-dependent transition from atoms to nanoparticles in magnetron sputtering: Effect on WSi2 film roughness and stress SO PHYSICAL REVIEW B LA English DT Article ID FCC-FE FILMS; X-RAY; MOLECULAR-DYNAMICS; COMPRESSIVE STRESS; GAS CONDENSATION; METAL-CLUSTERS; THIN-FILMS; GROWTH; MULTILAYERS; DEPOSITION AB We report on the transition between two regimes from several-atom clusters to much larger nanoparticles in Ar magnetron sputter deposition of WSi2, and the effect of nanoparticles on the properties of amorphous thin films and multilayers. Sputter deposition of thin films is monitored by in situ x-ray scattering, including x-ray reflectivity and grazing incidence small-angle x-ray scattering. The results show an abrupt transition at an Ar background pressure P-c; the transition is associated with the threshold for energetic particle thermalization, which is known to scale as the product of the Ar pressure and the working distance between the magnetron source and the substrate surface. Below P-c smooth films are produced while above P-c roughness increases abruptly, consistent with a model in which particles aggregate in the deposition flux before reaching the growth surface. The results from WSi2 films are correlated with in situ measurement of stress in WSi2/Si multilayers, which exhibits a corresponding transition from compressive to tensile stress at P-c. The tensile stress is attributed to coalescence of nanoparticles and the elimination of nanovoids.

This article discusses how predictions for direct detection experiments depend on uncertainties in quenching factor measurements, the dark matter interaction with the standard model, and the halo velocity distribution.
