AB Nonlinear Zeeman (NLZ) shifts arising from magnetic-field mixing of the two hyperfine ground states in alkali-metal atoms lead to splitting of magnetic-resonance lines. This is a major source of sensitivity degradation and the so-called "heading errors" of alkali-metal-vapor atomic magnetometers operating in the geophysical field range (B approximate to 0.2-0.7 G). Here, it is shown theoretically and experimentally that NLZ shifts can be effectively canceled by light shifts caused by a laser field of appropriate intensity, polarization, and frequency, a technique that can be readily applied in practical situations.

AB In a recent Comment, Decca [Phys. Rev. A 79, 026101 (2009)] discussed the origin of the anomalies recently reported by us in Phys. Rev. A 78, 036102(R) (2008). Here we restate our view corroborated by their considerations that quantitative geometrical and electrostatic characterizations of the conducting surfaces (a topic not discussed explicitly in the literature until very recently) are critical for the assessment of precision and accuracy of the demonstration of the Casimir force and for deriving meaningful limits on the existence of Yukawian components possibly superimposed to the Newtonian gravitational interaction.

AB We discuss the formation of molecular oxygen in ultracold collisions between hydroxyl radicals and atomic oxygen. A time-independent quantum formalism based on hyperspherical coordinates is employed for the calculations. Elastic, inelastic, and reactive cross sections as well as the vibrational and rotational populations of the product O(2) molecules are reported. A J-shifting approximation is used to compute the rate coefficients. At temperatures T=10-100 mK for which the OH molecules have been cooled and trapped experimentally, the elastic and reactive rate coefficients are of comparable magnitude, while at colder temperatures, T < 1 mK, the formation of molecular oxygen becomes the dominant pathway. The validity of a classical capture model to describe cold collisions of OH and O is also discussed. While very good agreement is found between classical and quantum results at T=0.3 K, at higher temperatures, the quantum calculations predict a larger rate coefficient than the classical model, in agreement with experimental data for the O+OH reaction. The zero-temperature limiting value of the rate coefficient is predicted to be about 6x10(-12) cm(3) molecule(-1) s(-1), a value comparable to that of barrierless alkali-metal atom-dimer systems and about a factor of five larger than that of the tunneling dominated F+H(2) reaction.

AB We study the properties of ThCr2Si2 structure BaMn2As2 and BaMn2Sb2 using density functional calculations of the electronic and magnetic properties as well as experimental measurements on single crystal samples of BaMn2As2. These materials are local moment magnets with moderate band gap antiferromagnetic semiconducting ground states. The electronic structures show substantial Mn-pnictogen hybridization, which stabilizes an intermediate spin configuration for the nominally d(5) Mn. The results are discussed in the context of possible thermoelectric applications and the relationship with the corresponding iron/cobalt/nickel compounds Ba(Fe,Co,Ni)(2)As-2.

AB Using in situ synchrotron x-ray photoelectron spectroscopy, we obtained high-resolution As 3d and Se 3d spectra of Se-rich As36Se64 glassy films during illumination with band-gap light. We report direct experimental evidence of the chemical origin of the light-induced scalar permanent change in the structure and, more interestingly, an indication of the chemical origin of the light-induced polarization-dependent (vector) effects. Our data show that the As atom plays a key role in both the permanent scalar effect and the vector effect. The latter is explained by the polarization-dependent interaction of homopolar -As-As- bonds in As4Se4 clusters with the band-gap light. The chemical reaction resulting from illumination explains anisotropic properties such as permanent light-induced mass transport.

AB The electronic structure of the p-type transparent conducting oxide CuCrO2 has been studied by x-ray photoemission, x-ray absorption, and x-ray emission spectroscopies. The upper part of the valence band derives mainly from Cu 3d and Cr 3d states while the lower valence-band states are of dominant O 2p atomic character, but with pronounced mutual hybridization among Cu 3d, Cr 3d, and O 2p states. Site specific electronic excitations have been studied by resonant inelastic x-ray scattering at the Cu L and Cr L edges. Inelastic loss at the Cu L edge is dominated by on-site interband excitations similar to those found in Cu2O, while at the Cr L edge localized excitations arising from ligand field splitting of the Cr 3d levels are observed. Mg doping on the Cr sites in CuCrO2 is shown to lead to a pronounced shift in the Fermi level toward the edge of the valence band. The experimental data are compared to electronic structure calculations on CuCrO2 carried out using density-functional methods corrected for onsite Coulomb repulsion.

AB We report As-75 nuclear magnetic resonance (NMR) data in a single crystal of CaFe2As2. The Knight shift, electric field gradient, and spin-lattice relaxation rate are strongly temperature dependent in the paramagnetic state and change discontinuously at the structural transition temperature, T-S=T-N=167 K. Immediately below, the NMR spectra reveal an internal field at the As site associated with the presence of a commensurate magnetic order. These results indicate that the structural and magnetic transitions in CaFe2As2 are first order and strongly coupled, and that the electron density in the FeAs plane is highly sensitive to the out-of-plane structure.

AB Monte Carlo and molecular-dynamics simulations are employed in a study of the equilibrium structural and thermodynamic properties of crystal-melt interfaces in a model binary alloy system described by Lennard-Jones interatomic interactions with zero size mismatch, a ratio of interaction strengths equal to 0.75, and interspecies interactions given by Lorentz-Berthelot mixing rules. This alloy system features a simple lens-type solid-liquid phase diagram at zero pressure, with nearly ideal solution thermodynamics in the solid and liquid solution phases. Equilibrium density profiles are computed for (100)-oriented crystal-melt interfaces and are used to derive the magnitudes of the relative adsorption coefficients (Gamma((j))(i)) at six temperatures along the solidus/liquidus boundary. The values for Gamma((2))(1), the relative adsorption of the lower melting-point species (1) with respect to the higher melting point species (2), are found to vary monotonically with temperature, with values that are positive and in the range of a few atomic percent per interface site. By contrast, values of Gamma((1))(2) display a much more complex temperature dependence with a large peak in the magnitude of the relative adsorption more than ten times larger than those found for Gamma((2))(1). The capillary fluctuation method is used to compute the temperature dependence of the magnitudes and anisotropies of the crystal-melt interfacial free energy (gamma). At all temperatures we obtain the ordering gamma(100)>gamma(110)>gamma(111) for the high-symmetry (100), (110), and (111) interface orientations. The values of gamma monotonically decrease with decreasing temperature (i.e., increasing concentration of the lower melting-point species). Using the calculated temperature-dependent values of gamma and Gamma((2))(1) in the Gibbs adsorption theorem, we estimate that roughly 25% of the temperature dependence of gamma for the alloys can be attributed to interface adsorption, while the remaining contribution arises from the relative excess entropy S-xs((2)).

AB We describe the construction of a three-phase equation of state for elemental beryllium. The phases considered are: the ambient hcp phase, the high-temperature bcc phase, and the liquid. The free energies of the solid phases are constructed from cold, ion-thermal, and electron-thermal components derived from ab initio electronic structure-based calculations. We find that the bcc phase is unstable near ambient conditions and that even at high pressures at which the bcc phase is stable, the bcc-hcp energy barrier can be as small as a few hundred kelvins. The liquid free energy is based on a model of Chisolm and Wallace and is constrained by using the melt curve (determined by ab initio two-phase simulations) as a reference. The high-temperature plasma limit is addressed with an average-atom-in-jellium model. Comparisons to experimental results, both for the ambient hcp phase and for the phase diagram as a whole, are discussed.

AB Heat capacity and anisotropic thermal expansion were measured for Ba(Fe1-xCox)(2)As-2 (x=0,0.038,0.074) single crystals. Thermal expansion is anisotropic and, in tetragonal phase, is significantly higher along the c axis. Previously reported phase transitions, including possibly split structural and magnetic for x=0.038, are clearly seen in both measurements. Uniaxial pressure derivatives of the superconducting transition temperature inferred from the Ehrenfest relation have opposite signs for in-plane and c-axis pressures for both Ba(Fe0.962Co0.038)(2)As-2 and Ba(Fe0.926Co0.074)(2)As-2, with the opposite sign of this anisotropy.

AB Pd-cluster-functionalized carbon nanotubes (CNTs) have been shown experimentally to be effective hydrogen sensors. Semiconducting CNTs exhibit much higher sensitivity than ensemble (mixed) ones. Using the nonequilibrium Green's function method combined with the density-functional theory, we simulate and contrast the (8,0) semiconducting and the (5,5) metallic CNT model systems. We find that the electron localization effect plays a crucial role in determining electron transport. Pd clusters and hydrogen adsorption cause opposite effects on electron localization in the CNT backbone for the semiconducting CNT-based systems. Consequently Pd functionalization dramatically increases the conductance, but then it is strongly suppressed by hydrogen absorption. For the metallic CNT-based systems, there is a tiny shift of the transmission peak near the Fermi energy. These results offer a consistent explanation for the experiments.

AB Monte Carlo simulations of cation doping within the ZnO lattice were utilized to evaluate dopant distributions in nanoparticles and thin films. In structures with a high surface-to-volume ratio, dopant distributions deviate significantly from predictions based on probabilistic expressions for infinitely large bulk lattices. We present empirical expressions that accurately predict dopant bonding configurations as a function of film or particle size, shape, and dopant concentration for any substitutional dopant (cation or anion) within a tetrahedrally coordinated compound, including zinc-blende, wurtzite, and diamond structures.

AB We present QMD simulations of water in the ultra-high-pressure regime up to conditions typical for the deep interior of Jupiter and Saturn. We calculate the equation of state and the Hugoniot curve and study the structural properties via pair correlation functions and self-diffusion coefficients. In the ultradense superionic phase, we find a continuous transition in the protonic structure. With rising density, the mobile protons stay with increasing probability at the octahedral sites while leaving the ice X positions to the same degree unoccupied. Water forms a fluid dense plasma at the conditions of Jupiter's core (i.e., 20 000 K, 50 Mbar, 11 g/cm(3)), while it may be superionic in the core of Saturn. We expect a substantial amount of superionic water inside Neptune.

AB Neutron scattering is used to study magnetic-field-induced ordering in the quasi-one-dimensional quantum spin-tube compound Sul-Cu(2)Cl(4) that in zero field has a nonmagnetic spin-liquid ground state. The experiments reveal an incommensurate chiral high-field phase stabilized by a geometric frustration of the magnetic interactions. The measured critical exponents beta approximate to 0.235 and nu approximate to 0.34 at H(c)approximate to 3.7 T point to an unusual subcritical scaling regime and may reflect the chiral nature of the quantum critical point.

AB X-ray absorption fine-structure (XAFS) measurements have been used to characterize a series of Co-doped ZnO films grown on sapphire substrates by pulsed laser deposition. The emphasis is on characterization of the fate of the Co dopant: metallic particles or substitutional Co2+. It is shown that analysis of both the near edge and extended fine structure can provide a measurement of the fraction of metallic Co. Any quantitative understanding of magnetism in this system needs to take into account both types of Co. Results are reported for two types of films from two different groups that show distinctly different behaviors. Films grown with high concentrations of Co show varying amounts of metallic Co that could be identified as a close-packed form of Co. Another set of films was annealed in Zn vapor to induce magnetism. These films also showed significant metallic Co, but of a different type similar to the CoZn intermetallic. The bulk forms of both metals are magnetic and should contribute to the magnetism. However, the measured room-temperature magnetic moments for some films are inconsistent with the expected moments based on the bulk magnetic values for either Co metal or CoZn. The magnetic properties of the small metal particles are likely changed by their surroundings. Low-temperature magnetic measurements for one of the samples confirmed this with an estimated blocking temperature of 50 K.

AB We have investigated structural, magnetic, and transport properties of Fe(Sb1-xTex)(2) single crystals. Whereas metallic ground state is induced for x=0.001, canted antiferromagnetism is observed for 0.1 <= x <= 0.4 with an intermediate ferromagnetic phase for x=0.2. With higher Te doping, semiconducting behavior is restored and the variable range hopping conduction mechanism dominates at low temperatures for 0.4 <= x <= 0.6. We discuss our results within the framework of inverted metal to insulator in correlated electron insulators.

The experimental PDF spectra clearly demonstrate that PZN-5%PT and PZN-12%PT have basically same ionic pair correlations up to the pair distance r similar to 15 A at all temperatures despite their difference in low-temperature long-range crystal structures. At longer pair distances 30 < r < 50 A, however, ionic pair correlations of PZN-5%PT and PZN-12%PT gradually diverge from each other below T similar to 450 K. Based on these PDF results, we propose that a distinct ordering of polar nanoregions develops between PZN-5%PT and PZN-12%PT with decreasing temperature.

ID DEPENDENCE; EXCITONS
AB We investigated excitation spectra of the one-dimensional chain compound Sr2CuO3. The small peak at 2.3 eV in the loss function turned out to correspond to the strong charge-transfer transition at 1.8 eV in conductivity. It has the excitonic character expected in one-dimensional extended Hubbard model of the transition from the lower Hubbard band to the Zhang-Rice singlet state. The strongest peak at 2.7 eV in the loss function is attributed to the continuum excitation of the excitonic charge-transfer transition. The spectral weight sum rule is satisfied within these transitions.

ID SUPERCONDUCTIVITY
AB We have investigated the low-energy electronic structure of the heavy-fermion superconductor CeCoIn5 by angle-resolved photoemission and band-structure calculations. We measured the Fermi surface and energy distribution maps along the high-symmetry directions at h nu=100 eV and T=25 K. The compound has quasi-two-dimensional Fermi-surface sheets centered at the M-A line of the Brillouin zone. The band-structure calculations have been carried out within the local-density approximation where the 4f electrons have been treated either localized or itinerant. We discuss the comparison to the experimental data and the implications for the nature of the 4f electrons at the given temperature.

TI Real-space ion scattering maps of the Mg(0001) surface
SO PHYSICAL REVIEW B
LA English
DT Article
ID ENERGY; RELAXATION; SPECTRA; SOLIDS
AB Low-energy ion scattering (LEIS) is useful for examining the structure of ordered surfaces as well as for identifying surface atoms. However, in some cases the structural information from LEIS measurements is obscured by complex collision processes which contribute to the detected scattering intensity. In this study, we have developed a more precise approach for examining surface structure that includes comparing experimental real-space ion scattering maps with simulations from binary collision codes using reliability factors. This method is demonstrated with the model system 2 keV Ne(+)-> Mg(0001). Using an angle-resolved ion energy spectrometer, the intensity of scattered Ne(+) from the surface was recorded for a complete set of polar and azimuthal angles, which define the orientation of the surface with respect to the incident beam. These angles were then transformed to distances in real space and used to compile an ion scattering map of the Mg(0001) surface. A simulated map was also generated for the same conditions using a modified version of the binary collision code MARLOWE. The maps provide a comprehensive overview of surface scattering and allow the locations of surface atoms to be correlated directly to regions of enhanced scattering intensity. The sensitivity of the LEIS signal to interatomic spacing was simulated using MARLOWE, and methods for comparing with experiments were developed. Because LEIS can distinguish different types of atoms on the surface, the techniques described here could be extended to map compound surfaces and adsorbates.

ID HYDROGEN STORAGE; ADSORPTION; SORPTION
AB Hydrogen adsorption by the metal-organic framework (MOF) structure Zn-2(BDC)(2)(TED) is investigated using a combination of experimental and theoretical methods. By using the nonempirical van der Waals density-functional approach, it is found that the locus of deepest H-2 binding positions lies within two types of narrow channel. The energies of the most stable binding sites, as well as the number of such binding sites, are consistent with the values obtained from experimental adsorption isotherms and heat of adsorption data. Calculations of the shift of the H-H stretch frequency when adsorbed in the MOF give a value of approximately -30 cm(-1) at the strongest binding point in each of the two channels. Ambient temperature infrared-absorption spectroscopy measurements give a hydrogen peak centered at 4120 cm(-1), implying a shift consistent with the theoretical calculations.

TI First-order magnetic and structural phase transitions in Fe1+ySexTe1-x

ID SUPERCONDUCTIVITY; DIAGRAM; SYSTEMS; FE2TE3; METAL; TE
AB We use bulk magnetic susceptibility, electronic specific heat, and neutron scattering to study structural and magnetic phase transitions in Fe1+ySexTe1-x. Fe1.068Te exhibits a first-order phase transition near 67 K with a tetragonal-to-monoclinic structural transition and simultaneously develops a collinear antiferromagnetic (AF) order responsible for the entropy change across the transition. Systematic studies of the FeSe1-xTex system reveal that the AF structure and lattice distortion in these materials are different from those of FeAs-based pnictides. These results call into question the conclusions of present density-functional calculations, where FeSe1-xTex and FeAs-based pnictides are expected to have similar Fermi surfaces and therefore the same spin-density wave AF order.

AB We report theoretical investigations that unveil unique electronic excitations in graphene nanoribbons of nanoscale length. The main point is that electronic states in short nanowires are standing particle-in-a-box-like waves, amenable to excitation by electromagnetic radiation. The unusual electronic and magnetic properties of graphene nanoribbons add another feature: terahertz (THz) radiation induces edge standing spin waves with different wavelengths at the two edges and a resonant frequency that can be controlled by an external gate voltage, opening the possibility of THz-spintronic applications.

AB The fine structure of oxygen-K electron energy-loss spectra (EELS) of transition-metal oxides is known to correlate with nominal oxidation states (NOSs) that are often interpreted as charge states. Here we report calculations of O-K EELS in LaxCa1-xMnO3 that agree with measured spectra and show that the variation in the prepeak's intensity with doping is controlled by the orbital occupancy of the majority-spin Mn 3d states, while its width is controlled by crystal-field splitting. The results confirm an earlier conclusion that the NOS extracted from EELS corresponds only to orbital occupancies, while the physical charge renders all atoms electrically neutral, even in so-called ionic crystals.

AB Inelastic x-ray scattering measurements of the phonon density of states (DOS) were performed on polycrystalline samples of pure alpha-Pu and delta-Pu(0.98)Ga(0.02) at room temperature. The heat capacity of alpha-Pu is well reproduced by contributions calculated from the measured phonon DOS plus conventional thermal-expansion and electronic contributions, showing that alpha-Pu is a "well-behaved" metal in this regard. A comparison of the phonon DOS of the two phases at room temperature showed that the vibrational entropy difference between them is only a quarter of the total entropy difference expected from known thermodynamic measurements. The missing entropy is too large to be accounted for by conventional electronic entropy and evidence from the literature rules out a contribution from spin fluctuations. Possible alternative sources for the missing entropy are discussed.

AB Our ab initio calculations of CO adsorption energies on low-Miller-index [(111) and (100)], stepped (211), and kinked (532) gold surfaces show a strong dependence on local coordination with a reduction in Au atom coordination leading to higher binding energies. We find trends in adsorption energies to be similar to those reported in experiments and calculations for other metal surfaces. The (532) surface provides insights into these trends because of the availability of a large number of kink sites which naturally have the lowest coordination (6). We also find that for all surfaces an increase in CO coverage triggers a decrease in the adsorption energy. Changes in the work function upon CO adsorption, as well as the frequencies of the CO vibrational modes, are calculated, and their coverage dependence is reported.

AB Previously measured in situ x-ray diffraction is used to assess the development of internal elastic strains within grains of a sample of polycrystalline cobalt plastically deformed up to a pressure of 42.6 GPa. An elastoplastic self-consistent polycrystal model is used to simulate the macroscopic flow curves and internal strain development within the sample. Input parameters are single-crystal elastic moduli and their pressure dependence, critical resolved shear stresses, and hardening behavior of the slip and twinning mechanisms which are active in Co crystals. At 42 GPa, the differential stress in hcp-Co is 1.9 +/- 0.1 GPa. The comparison between experimental and predicted data leads us to conclude that: (a) plastic relaxation plays a primary role in controlling the evolution and ordering of the lattice strains; (b) the plastic behavior of hcp-Co deforming under high pressure is controlled by basal and prismatic slip of < a > dislocations, and either pyramidal slip of < c+a > dislocations, or compressive twinning, or both. Basal slip is by far the easiest and most active deformation mechanism. Elastoplastic self-consistent models are shown to overcome the limitations of models based on continuum elasticity theory for the interpretation of x-ray diffraction data measured on stressed samples. They should be used for the interpretation of these experiments.

AB Using soft x-ray spectromicroscopy we show that NiO(001) exhibits a crystallographic and magnetic domain structure near the surface identical to that of the bulk. Upon Co deposition a perpendicular coupling between the Ni and Co moments is observed that persists even after formation of uncompensated Ni spins at the interface through annealing. The chemical composition at the interface alters its crystallographic structure and leads to a reorientation of the Ni moments from the < 112 > to the < 110 > direction. We show that this reorientation is driven by changes in the magnetocrystalline anisotropy rather than exchange coupling mediated by residual uncompensated spins.

AB Nitrogen-doped TiO2 materials have been shown to exhibit visible-light photoactivity, but the operative mechanism(s) are not well understood. Here we use structurally and compositionally well-defined epitaxial films of TiO2-xNx anatase (001) and rutile (110) (x <=similar to 0.02) to show a qualitative difference between the visible-light activities for the two polymorphs. Holes generated by visible light at N sites in anatase (001) readily diffuse to the surface and oxidize adsorbed trimethyl acetate while the same in rutile (110) remain trapped in the bulk. In light of the low doping densities that can be achieved in phase-pure material, conventional wisdom suggests that holes should be trapped at N sites in both polymorphs. Although the detailed mechanism is not yet understood, these results suggest that the hole hopping probability is much higher along the [001] direction in N-doped anatase than along the [110] direction in N-doped rutile.

superconductors; neutron diffraction; spin fluctuations
ID NEUTRON-SCATTERING; SUPERCONDUCTIVITY
AB Inelastic neutron-scattering measurements of CaFe2As2 under applied hydrostatic pressure show that the antiferromagnetic spin fluctuations observed in the ambient pressure, paramagnetic, and tetragonal (T) phase are strongly suppressed, if not absent, in the collapsed tetragonal (cT) phase. These results are consistent with a quenched Fe moment in the cT phase and the strong decrease in resistivity observed upon crossing the boundary from the T to cT phases. The suppression or absence of static antiferromagnetic order and dynamic spin fluctuations in the nonsuperconducting cT phase supports the notion of a coupling between spin fluctuations and superconductivity in the iron arsenides.

AB We present a detailed infrared study of the insulator-to-metal transition (IMT) in vanadium dioxide (VO(2)) thin films. Conventional infrared spectroscopy was employed to investigate the IMT in the far field. Scanning near-field infrared microscopy directly revealed the percolative IMT with increasing temperature. We confirmed that the phase transition is also percolative with cooling across the IMT. We present extensive near-field infrared images of phase coexistence in the IMT regime in VO(2). We find that the coexisting insulating and metallic regions at a fixed temperature are static on the time scale of our measurements. A distinctive approach for analyzing the far-field and near-field infrared data within the Bruggeman effective medium theory was employed to extract the optical constants of the incipient metallic puddles at the onset of the IMT. We found divergent effective carrier mass in the metallic puddles that demonstrates the importance of electronic correlations to the IMT in VO(2). We employ the extended dipole model for a quantitative analysis of the observed near-field infrared amplitude contrast and compare the results with those obtained with the basic dipole model.

AB Valence-band and conduction-band edges of ultrathin oxides (SiO2, HfO2, Hf0.7Si0.3O2, and Al2O3 grown on silicon) and their shifts upon sequential metallization with ruthenium have been measured using synchrotron-radiation-excited x-ray, ultraviolet, and inverse photoemissions. From these techniques, the offsets between the valence-band and conduction-band edges of the oxides, and the ruthenium metal gate Fermi edge have been directly measured. In addition the core levels of the oxides and the ruthenium have been characterized. Upon deposition, Ru remains metallic and no chemical alteration of the underlying oxide gates, or interfacial SiO2 in the case of the high-kappa thin films, can be detected. However a clear shift of the band edges is measured for all samples due to the creation of an interface dipole at the ruthenium-oxide interface. Using the energy gap, the electron affinity of the oxides, and the ruthenium work function that have been directly measured on these samples, the experimental band offsets are compared to those predicted by the induced gap states model.

AB We show that in the severe slowing-down temperature regime the relaxation of antiferromagnetic rings and similar magnetic nanoclusters is governed by the quasicontinuum portion of their quadrupolar fluctuation spectrum and not by the lowest excitation lines. This is at the heart of the intriguing near-universal power-law temperature dependence of the electronic correlation frequency omega(c) with an exponent close to 4. The onset of this behavior is defined by an energy scale which is fixed by the lowest spin gap Delta(0). This explains why the experimental curves of omega(c) for different cluster sizes and spins nearly coincide when T is rescaled by Delta(0).

AB The density-functional spin susceptibility has been analyzed in different phases of CaFe2As2 and compared with similar data for pure d metals. The conditions for the "no local-moment" itinerant state with large frustrations are found for the "collapsed" phase. This itineracy determines the instability versus the incommensurate magnetic order for the narrow region of wave vectors. For the ambient pressure phase, the local moments on Fe atoms with much less frustrated antiferromagnetic interactions are stabilized and a magnetic short-range or long-range order is developed. The system is close to the point of magnetic instability and spin fluctuations should be included to describe properties of this system.

AB The measured thermodynamic phase diagram of the quasi-two-dimensional magnet [Cu(HF2)(pyz)(2)]BF4(pyz=pyrazine=N2C4H4) exhibits an unusual nonmonotonic dependence of the Neel temperature T-N as a function of magnetic field H. The nonmonotonic behavior of T-N(H) results from two competing effects induced by the field: while H suppresses the amplitude of the order parameter by polarizing the spins along a given direction, it also reduces the phase fluctuations by changing the order parameter space from the sphere S-2 to the circle S-1. The latter effect dominates at low fields only if the system is close enough to its lower critical dimension (d(c)=2), i.e., when fluctuations become important. Our theoretical results reproduce the measured phase diagram and demonstrate that this unusual effect is realized in [Cu(HF2)(pyz)(2)]BF4.

TI Anisotropy of the pairing gap of FeAs-based superconductors induced by
spin fluctuations

anisotropy; type II superconductors
ID SYSTEMS; ORDER
AB We determine the anisotropy of the spin-fluctuation-induced pairing gap on the Fermi surface of the FeAs-based superconductors as function of the exchange and Hund's coupling J(H). We find that for sufficiently large J(H), nearly commensurate magnetic fluctuations yield a fully gapped s(+/-)-pairing state with small anisotropy of the gap amplitude on each Fermi-surface sheet, but significant variations of the gap amplitude for different sheets of the Fermi surface. In particular, we obtain the large variation of the gap amplitude on different Fermi-surface sheets, as seen in angular resolved photoemission spectroscopy experiments. For smaller values of Hund's coupling incommensurate magnetic fluctuations yield an s(+/-)-pairing state with line nodes. Such a state is also possible once the anisotropy of the material is reduced and three-dimensional effects come into play.

AB In the present work we show that a particular family of materials, the metal carboxylates, may have entangled states up to very high temperatures. From magnetic-susceptibility measurements, we have estimated the critical temperature below which entanglement exists in the copper carboxylate {Cu-2(O2CH)(4)}{Cu(O2CH)(2)(2-methylpyridine)(2)}, and we have found this to be above room temperature (T-e similar to 630 K). Furthermore, the results show that the system remains maximally entangled until close to similar to 100 K and the Bell's inequality is violated up to nearly room temperature (similar to 290 K).

AB We study the spin transport properties of the noncentrosymmetric superconductor with time-reversal symmetry where spin-triplet (p(x)+/- ip(y))-wave and spin-singlet s-wave pair potentials can mix with each other. We show that when the amplitude of the (p(x)+/- ip(y))-wave pair potential is larger than that of s-wave one, the superconducting state belongs to the topologically nontrivial class analogous to the quantum spin Hall system, and the resulting helical edge modes as Andreev bound states are topologically protected. We find that the incident angle dependent spin polarized current flows through the interface due to the presence of the helical edge modes. With a weak magnetic field, also the angle-integrated current is strongly spin polarized.

AB Aberration corrected electron optics allows routine acquisition of high spatial resolution spectroscopic images in the scanning transmission electron microscope, which is important when trying to understand the physics of transition-metal oxides such as manganites. The physical properties of these perovskites are intimately related to the occupancies of the partially filled 3d bands, which define their oxidation state. In this work, we review procedures to obtain this electronic property in La(x)Ca(1-x)MnO(3) from atomic-column-resolved electron energy-loss spectra measured in the aberration corrected scanning transmission electron microscope. In bulk samples, several features of both the average Mn L(2,3) edge and the O K edge fine structure change linearly with Mn nominal valence. These linear correlations are extracted and used as a calibration to quantify oxidation states from atomic resolution spectroscopic images. In such images, the same fine-structure features exhibit further changes, commensurate with the underlying atomic lattice. Mn valence values calculated from those images show unexpected oscillations. The combination of experiment with density-functional theory and dynamical scattering simulations allows detailed interpretation of these maps, distinguishing dynamical scattering effects from actual changes in electronic properties related to the local atomic structure. Specifically, in LaMnO(3), the two nonequivalent O sites can be distinguished by these methods.

AB Ternary oxides formed from zinc and indium have demonstrated potential for commercial optoelectronic applications. We present state-of-the-art hybrid density functional theory calculations for Zn-poor and Zn-rich compositions of the crystalline In2O3(ZnO)(n) compounds. We reveal the origin of the redshift in optical transitions compared to the two component oxides: symmetry forbidden band-edge transitions in In2O3 are overcome on formation of the superlattices, with Zn-O contributions to the top of the valence band. Increasing n results in the localization of the conduction-band minimum on the In-O networks. This enhanced localization explains why Zn-poor compounds (lower n) exhibit optimal conductivity.

AB Ca3CoMnO6 is composed of CoMnO6 chains made up of face-sharing CoO6 trigonal prisms and MnO6 octahedra. The structural, magnetic, and ferroelectric properties of this compound were investigated on the basis of density-functional theory calculations. Ca3CoMnO6 is found to undergo a Jahn-Teller distortion associated with the CoO6 trigonal prisms containing high-spin Co2+ (d(7)) ions, which removes the C-3 rotational symmetry and hence uniaxial magnetism. However, the Jahn-Teller distortion is not strong enough to fully quench the orbital moment of the high-spin Co2+ ions thereby leading to an electronic state with substantial magnetic anisotropy. The Jahn-Teller distorted Ca3CoMnO6 in the magnetic ground state with up-up-down-down spin arrangement is predicted to have electric polarizations much greater than experimentally observed. Implications of the discrepancy between theory and experiment were discussed.

AB We present measurements of net charge fluctuations in Au+Au collisions at s(NN)=19.6, 62.4, 130, and 200 GeV, Cu+Cu collisions at s(NN)=62.4 and 200 GeV, and p+p collisions at s=200 GeV using the dynamical net charge fluctuations measure nu(+-,dyn). We observe that the dynamical fluctuations are nonzero at all energies and exhibit a modest dependence on beam energy. A weak system size dependence is also observed. We examine the collision centrality dependence of the net charge fluctuations and find that dynamical net charge fluctuations violate 1/N-ch scaling but display approximate 1/N-part scaling. We also study the azimuthal and rapidity dependence of the net charge correlation strength and observe strong dependence on the azimuthal angular range and pseudorapidity widths integrated to measure the correlation.

AB The Zn-61(30)31 nucleus has been studied via the combined data of two fusion-evaporation reaction experiments using a Ar-36 beam and a Si-28 target foil. The experimental setups involved the Ge array GAMMASPHERE and neutron and charged particle detectors placed around the target position. The resulting level scheme comprises about 120 excited states connected via some 180 gamma-ray transitions. In total, seven rotational structures were identified up to I similar to 25 or higher and compared with predictions from cranked Nilsson-Strutinsky calculations.

AB The excitation function for the Pb-208(Cr-52,n)(259)Sg reaction has been measured using the Berkeley Gas-filled Separator at the Lawrence Berkeley National Laboratory 88-Inch Cyclotron. The maximum cross section of 320(-100)(+110) pb is observed at a center-of-target laboratory-frame energy of 253.0 MeV. In total, 25 decay chains originating from (259)Sg were observed and the measured decay properties are in good agreement with previous reports. In addition, a partial excitation function for the Pb-208(Cr-52,2n)(258)Sg reaction was obtained, and an improved (258)Sg half-life of 2.6(-0.4)(+0.6) ms was calculated by combining all available experimental data.

TI Charge radii and electromagnetic moments of Li and Be isotopes from the
ab initio no-core shell model
SO PHYSICAL REVIEW C
LA English
DT Article
ID ENERGY-LEVELS; NUCLEI; SHIFT
AB Recently, charge radii and ground-state electromagnetic moments of Li and Be isotopes were measured precisely. We have performed large-scale ab initio no-core shell model calculations for these isotopes using high-precision nucleon-nucleon potentials. The isotopic trends of our computed charge radii and quadrupole and magnetic-dipole moments are in good agreement with experimental results with the exception of the Li-11 charge radius. The magnetic moments are in particular well described, whereas the absolute magnitudes of the quadrupole moments are about 10% too small. The small magnitude of the Li-6 quadrupole moment is reproduced, and with the CD-Bonn NN potential, also its correct sign.

AB We estimate the energy density and the gluon distribution associated with the classical fields describing the early-time dynamics of heavy-ion collisions. In the McLerran-Venugopalan model, we first decompose the energy density into the momentum components exactly, with the use of the Wilson line correlators. Then we evolve the energy density with the free-field equation, which is justified by the dominance of the ultraviolet modes near the collision point. We also discuss the improvement that occurs with the inclusion of nonlinear terms into the time evolution. Our numerical results at RHIC energy are fairly consistent with the empirical values.

MESON PRODUCTION
AB As a step toward performing a complete coupled-channels analysis of the world data of pi N,gamma(*)N ->pi N,eta N,pi pi N reactions, the pi N ->pi pi N reactions are investigated starting with the dynamical coupled-channels model developed in Phys. Rev. C 76, 065201 (2007). The channels included are pi N,eta N, and pi pi N which has pi Delta,rho N, and sigma N resonant components. The nonresonant amplitudes are generated from solving a set of coupled-channels equations with the meson-baryon potentials defined by effective Lagrangians. The resonant amplitudes are generated from 16 bare excited nucleon (N(*)) states that are dressed by the nonresonant interactions as constrained by the unitarity condition. The data of total cross sections and pi N and pi pi invariant mass distributions of pi(+)p ->pi(+)pi(+)n,pi(+)pi(0)p and pi(-)p ->pi(+)pi(-)n,pi(-)pi(0)p,pi(0)pi(0)n reactions from threshold to the invariant mass W=2 GeV can be described to a very large extent. We show the importance of the coupled-channels effects and the strong interference among the contributions from the pi Delta,sigma N, and rho N channels. The large interference between the resonant and nonresonant amplitudes is also demonstrated. Possible future developments are discussed.

TI Nuclear structure relevant to neutrinoless double beta decay: The
valence protons in Ge-76 and Se-76
SO PHYSICAL REVIEW C
LA English
DT Article
ID HE-3; OCCUPANCIES; SCATTERING; AS-77
AB The possibility of observing neutrinoless double beta decay offers the opportunity of determining the effective neutrino mass if the nuclear matrix element were known. Theoretical calculations are uncertain, and the occupation of valence orbits by nucleons active in the decay is likely to be important. The occupation of valence proton orbits in the ground states of Ge-76, a candidate for such decay, and Se-76, the corresponding daughter nucleus, is determined by precisely measuring cross sections for proton-removing transfer reactions. As in previous work on neutron occupation, we find that the Fermi surface for protons is much more diffuse than previously thought, and the occupancies of at least three orbits change significantly between the two 0(+) ground states.

AB An experiment aimed at the synthesis of isotopes of element 120 has been performed using the Pu-244(Fe-58,xn)(302-x)120 reaction. No decay chains consistent with fusion-evaporation reaction products were observed during an irradiation with a beam dose of 7.1x10(18) 330-MeV Fe-58 projectiles. The sensitivity of the experiment corresponds to a cross section of 0.4 pb for the detection of one decay.

AB A global optical model potential (GDP08) for (3)He projectiles has been obtained by simultaneously fitting the elastic scattering data of (3)He from targets of 40 <= A(T)<= 209 at incident energies of 30 <= E(inc)<= 217 MeV. Uncertainties and correlation coefficients between the global potential parameters were obtained by using the bootstrap statistical method. GDP08 was found to satisfactorily account for the elastic scattering of (3)H as well, which makes it a global optical potential for the A=3 nuclei. Optical model calculations using the GDP08 global potential are compared with the experimental angular distributions of differential cross sections for (3)He-nucleus and (3)H-nucleus scattering from different targets of 6 <= A(T)<= 232 at incident energies of 4 <= E(inc)<= 450 MeV. The optical potential for the doubly-magic nucleus (40)Ca, the low-energy correction to the real potential for nuclei with 58 less than or similar to A(T)less than or similar to 120 at E(inc)< 30 MeV, the comparison with double-folding model calculations and the CH89 potential, and the spin-orbit potential parameters are discussed.

AB The dynamical coupled-channels approach developed at the Excited Baryon Analysis Center is extended to include the omega N channel to study pi- and omega-meson production induced by scattering pions and photons from the proton. Six intermediate channels, including pi N, eta N, pi Delta, sigma N, rho N, and omega N, are employed to describe unpolarized and polarized data. Bare parameters in an effective hadronic Lagrangian are determined in a fit to the data for pi N ->pi N, gamma N ->pi N, pi(-)p ->omega n, and gamma p ->omega p reactions at center-of-mass energies from threshold to W < 2.0 GeV. The T matrix determined in these fits is used to calculate the photon beam asymmetry for omega-meson production and the omega N ->omega N total cross section and omega N-scattering lengths. The calculated beam asymmetry is in good agreement with the observed in the range of energies near threshold to W less than or similar to 2.0 GeV.

AB Medium-spin structure of neutron rich nuclei Sr-92, Sr-94, and Sr-96 have been studied in spontaneous fission of Cm-248. New spin and parity assignments done in this work differ significantly from those reported in other works. The 9(-) excitations, involving the nu(g(7/2)h(11/2))(9)(-) maximum aligned configuration, were proposed in the three nuclei at 4930.2 keV, 4858.6 keV, and 3523.9 keV, respectively. Shell-model calculations, with the Ni-78 core, support the proposed nature of the 9(-) excitations. The new data allow testing the single-particle energies in the region of Ni-78, and in particular, the position of the nu h(11/2) orbital, which was not uniquely determined to date.

AB The gamma-ray cascades following the Mo-95(n,gamma)Mo-96 reaction were studied with the gamma calorimeter DANCE (Detector for Advanced Neutron Capture Experiments) consisting of 160 BaF2 scintillation detectors at the Los Alamos Neutron Science Center. The gamma-ray energy spectra for different multiplicities were measured for s- and p-wave resonances below 2 keV. The shapes of these spectra were found to be in very good agreement with simulations using the DICEBOX statistical model code. The relevant model parameters used for the level density and photon strength functions were identical with those that provided the best fit of the data from a recent measurement of the thermal Mo-95(n,gamma)Mo-96 reaction with the two-step-cascade method. The reported results strongly suggest that the extreme statistical model works very well in the mass region near A=100.

AB We present a pedagogical study of the commonly employed speed-plot (SP) and time-delay (TD) methods for extracting the resonance parameters from the data of two-particle coupled-channels reactions. Within several exactly solvable models, it is found that these two methods find poles on different Riemann sheets and are not always valid. We then develop an analytic continuation method for extracting nucleon resonances within a dynamical coupled-channel formulation of pi N and gamma N reactions. The main focus of this paper is on resolving the complications from the coupling with the unstable pi Delta, rho N, and sigma N channels, which decay into pi pi N states. By using the results from the considered exactly solvable models, explicit numerical procedures are presented and verified. As a first application of the developed analytic continuation method, we present the nucleon resonances in some partial waves extracted within a recently developed coupled-channels model of pi N reactions. The results from this realistic pi N model, which includes pi N, eta N, pi Delta, rho N, and sigma N channels, also show that the simple pole parametrization of the resonant propagator using the poles extracted from SP and TD methods works poorly.

AB High-spin states populated in the decay of microsecond isomers in the transitional nuclei Sb-121 and Sb-123 have been investigated in detail in several experiments using gamma-ray and electron spectroscopy. The nuclei were formed using multinucleon transfer and fusion-fission reactions with Xe-136 beams and also using the Sn-120(Li-7,alpha 2n)Sb-121 and Sn-122(Li-7,alpha 2n)Sb-123 incomplete-fusion reactions. Isomeric half-lives ranging from several nanoseconds to a few hundred microseconds were determined by means of conventional decay curve analyses, whereas very short-lived isomers (T(1/2 similar to)1 ns) were identified using the generalized centroid-shift method. A number of new transitions were observed, including a branch through spherical states from the 19/2(+) member of the 9/2(+) deformed band in Sb-121, in competition with the main decay path through the rotational band. This is attributed to mixing between the 19/2(+) band member and a 19/2(+) spherical state. Both levels are predicted to coincide approximately in energy in Sb-121. The fact that a 25/2(+) isomer occurs for A=121 and the lighter isotopes, while a 23/2(+) isomer is observed for A=123-131 is explained through a multistate mixing calculation, taking into account the gradual shift of the 2d(5/2) and 1g(7/2) proton orbitals and the change in proton-neutron effective interactions from an attractive particle-particle type in the lower part of the shell to a repulsive particle-hole type with increasing the neutron number toward the N=82 shell closure. The observed enhancement of the B(E2;19/2(-)-> 15/2(-)) values in Sb-121 and Sb-123 over the B(E2;7(-)-> 5(-)) values in the corresponding Sn cores is discussed in terms of configuration mixing between spherical and deformed states.

AB This article presents the first measurement of the ratio of branching fractions B(Lambda(0)(b) -> Lambda(+)(c) mu(-) (nu) over bar (mu))/B(Lambda(0)(b) -> Lambda(+)(c) pi(-)). Measurements in two control samples using the same technique B((B) over bar (0) -> D+ mu(-) (nu) over bar (mu))/B((B) over bar (0) -> D+ pi(-)) and B((B) over bar (0) -> D*(2010)(+) mu(-) (nu) over bar (mu))/B((B) over bar (0) -> D*(2010)(+) pi(-)) are also reported. The analysis uses data from an integrated luminosity of approximately 172 pb(-1) of p (p) over bar collisions at root s = 1: 96 TeV, collected with the CDF II detector at the Fermilab Tevatron. The relative branching fractions are measured to be B(Lambda(0)(b) -> Lambda(+)(c) mu(-) (nu) over bar (mu))/B(Lambda(0)(b) -> Lambda(+)(c) pi(-)) = 16.6 +/- 3.0(stat) +/- 1.0(syst) (+2.6)(-3.4) (PDG) +/- 0.3(EBR), B((B) over bar (0) -> D+ mu(-) (nu) over bar (mu))/B((B) over bar (0) -> D+ pi(-)) = 9.9 +/- 1.0(stat) +/- 0.6(syst) +/- 0.4(PDG) +/- 0.5(EBR), and B((B) over bar (0)-> D*(2010)(+) mu(-) (nu) over bar (mu))/B((B) over bar (0) -> D*(2010)(+) pi(-)) = 16.5 +/- 2.3(stat) +/- 0.6(syst) +/- 0.5(PDG) +/- 0.8(EBR). The uncertainties are from statistics (stat), internal systematics (syst), world averages of measurements published by the Particle Data Group or subsidiary measurements in this analysis (PDG), and unmeasured branching fractions estimated from theory (EBR), respectively. This article also presents measurements of the branching fractions of four new Lambda(0)(b) semileptonic decays: Lambda(0)(b) -> Lambda(c)(2595)(+) mu(-) (nu) over bar (mu), Lambda(0)(b) -> Lambda(c)(2625)(+) mu(-) (nu) over bar (mu), Lambda(0)(b) -> Sigma(c)(2425)(0) pi(+) mu(-) (nu) over bar (mu) , and Lambda(0)(b) -> Sigma(c)(2455)(++) pi(-) mu(-) (nu) over bar (mu), relative to the branching fraction of the Lambda(0)(b) -> Lambda(+)(c) mu(-) (nu) over bar (mu) decay. Finally, the transverse-momentum distribution of Lambda(0)(b) baryons produced in p (p) over bar collisions is measured and found to be significantly different from that of (B) over bar (0) mesons, which results in a modification in the production crosssection ratio sigma(Lambda b0)/sigma((B) over bar0) with respect to the CDF I measurement.

ID QUARK PAIR PRODUCTION; SPIN CORRELATIONS; COLLIDERS
AB We present a measurement of the ratio of the t (t) over bar production cross section via gluon-gluon fusion to the total t (t) over bar production cross section in p (p) over bar collisions at root s = 1.96 Tev at the Tevatron. Using a data sample with an integrated luminosity of 955 pb(-1) recorded by the CDF II detector at Fermilab, we select events based on the t (t) over bar decay to lepton + jets. Using an artificial neural network technique we discriminate between t (t) over bar events produced via q (q) over bar annihilation and gg fusion, and find G(f) = sigma(gg -> t (t) over bar/sigma(p (p) over bar -> t (t) over bar) < 0.33 at the 68% confidence level. This result is combined with a previous measurement to obtain the most stringent measurement of this quantity by CDF to date, G(f) = 0.07(-0.07)(+0.15).

ID BOSON PRODUCTION; QCD
AB The very large K factor for Higgs-boson production at hadron colliders is shown to result from enhanced perturbative corrections of the form (C-A pi alpha(s))(n), which arise in the analytic continuation of the gluon form factor to timelike momentum transfer. These terms are resummed to all orders in perturbation theory using the renormalization group. After the resummation, the K factor for the production of a light Higgs boson at the LHC is reduced to a value close to 1.3.

ALGORITHM; QUARK MASSES; GAUGE-THEORY
AB We present the first results of the PACS-CS project which aims to simulate 2 + 1 flavor lattice QCD on the physical point with the nonperturbatively O(a)-improved Wilson quark action and the Iwasaki gauge action. Numerical simulations are carried out at beta = 1.9, corresponding to the lattice spacing of a = 0.0907(13) fm, on a 32(3) X 64 lattice with the use of the domain-decomposed HMC algorithm to reduce the up-down quark mass. Further algorithmic improvements make possible the simulation whose up-down quark mass is as light as the physical value. The resulting pseudoscalar meson masses range from 702 MeV down to 156 MeV, which clearly exhibit the presence of chiral logarithms. An analysis of the pseudoscalar meson sector with SU(3) chiral perturbation theory reveals that the next-to-leading order corrections are large at the physical strange quark mass. In order to estimate the physical up-down quark mass, we employ the SU(2) chiral analysis expanding the strange quark contributions analytically around the physical strange quark mass. The SU(2) low energy constants (l) over bar (3) and (l) over bar (4) are comparable with the recent estimates by other lattice QCD calculations. We determine the physical point together with the lattice spacing employing m(pi), m(K) and m(Omega) as input. The hadron spectrum extrapolated to the physical point shows an agreement with the experimental values at a few % level of statistical errors, albeit there remain possible cutoff effects. We also find that our results of f(pi), f(K) and their ratio, where renormalization is carries out perturbatively at one loop, are compatible with the experimental values. For the physical quark masses we obtain m(ud)((MS) over bar) and m(s)((MS) over bar) extracted from the axial-vector Ward-Takahashi identity with the perturbative renormalization factors. We also briefly discuss the results for the static quark potential.

AB In this paper we present a comprehensive formalism for dilepton production from the collision of two polarized spin-1/2 hadrons by identifying the general angular distribution of the cross section in combination with a complete set of structure functions. The various structure functions are computed in the parton model approximation where we mainly consider the case when the transverse momentum of the dilepton pair is much smaller than its invariant mass. In this kinematical region dilepton production can be described in terms of transverse momentum dependent parton distributions.

TI Dalitz plot analysis of D-s(+)->pi(+)pi(-)pi(+)
SO PHYSICAL REVIEW D
LA English
DT Article
ID PI(-)PI(+)PI(+) DECAY; MESONS; D-S(+); D+
AB A Dalitz plot analysis of approximately 13 000 D-s(+) decays to pi(+)pi(-)pi(+) has been performed. The analysis uses a 384 fb(-1) data sample recorded by the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage ring running at center of mass energies near 10.6 GeV. Amplitudes and phases of the intermediate resonances which contribute to this final state are measured. A high precision measurement of the ratio of branching fractions is performed: B(D-s(+)->pi(+)pi(-)pi(+))/B(D-s(+)-> K+K-pi(+))=0.199 +/- 0.004 +/- 0.009. Using a model-independent partial wave analysis, the amplitude and phase of the S wave have been measured.

ID VIOLATING ASYMMETRIES; PARTICLE PHYSICS; SEARCH
AB We present new measurements of time-dependent CP asymmetries for B-0 -> D-(*()+) D-(*()-) decays using (467 +/- 5) X 10(6) B (B) over bar pairs collected with the BABAR detector located at the PEP-II B Factory at the Stanford Linear Accelerator Center. We determine the CP-odd fraction of the B-0 -> D-(*()+) D-(*()-) decays to be R-perpendicular to = 0.158 +/- 0.028 +/- 0.006 and find CP asymmetry parameters S+ = -0.76 +/- 0.16 +/- 0.04 and C+ = +0.00 +/- 0.12 +/- 0.02 for the CP-even component of this decay and S-perpendicular to = -1.80 +/- 0.70 +/- 0.16 and C-perpendicular to = +0.41 +/- 0.49 +/- 0.08 for the CP-odd component. We measure S = -0.63 +/- 0.36 +/- 0.05 and C = -0.07 +/- 0.23 +/- 0.03 for B-0 -> D+D-, S = -0.62 +/- 0.21 +/- 0.03 and C = +0.08 +/- 0.17 +/- 0.04 for B-0 -> D*D-+(-), and S = -0.73 +/- 0.23 +/- 0.05 and C = +0.00 +/- 0.17 +/- 0.03 for B-0 -> D+D*(-). For the B-0 -> D*(+/-) D-+/- decays, we also determine the CP-violating asymmetry (A) over bar = +0.008 +/- 0.048 +/- 0.013. In each case, the first uncertainty is statistical and the second is systematic. The measured values for the asymmetries are all consistent with the standard model.

DT Article
AB We use a sample of 384 X 10(6) B (B) over bar events collected with the BABAR detector at the PEP-II e(+)e(-) collider to study angular distributions in the rare decays B -> K(*)l(+)l(-), where l(+)l(-) is either e(+)e(-) or mu(+)mu(-). For low dilepton invariant masses, m(ee) < 2.5 GeV/c(2), we measure a lepton forward-backward asymmetry A(FB) = 0.24(-0.23)(+0.18) +/- 0.05 and K* longitudinal polarization F-L = 0.35 +/- 0.16 +/- 0.04. For m(ee) > 3.2 GeV/c(2), we measure A(FB) = 0.76(-0.32)(+0.52) +/- 0.07 F-L = 0.71(-0.22)(+0.20) +/- 0.04.

AB Using a model calculation of dihadron fragmentation functions, we fit the spin asymmetry recently extracted by HERMES for the semi-inclusive pion pair production in deep-inelastic scattering on a transversely polarized proton target. By evolving the obtained dihadron fragmentation functions, we make predictions for the correlation of the angular distributions of two pion pairs produced in electron-positron annihilations at BELLE kinematics. Our study shows that the combination of two-hadron inclusive deep-inelastic scattering and electron-positron annihilation measurements can provide a valid alternative to Collins effect for the extraction of the quark transversity distribution in the nucleon.

SO PHYSICAL REVIEW D

AB We propose a model for D+->pi(+)pi(-)pi(+) decays following experimental results which indicate that the two-pion interaction in the S wave is dominated by the scalar resonances f(0)(600)/sigma and f(0)(980). The weak decay amplitude for D+-> R pi(+), where R is a resonance that subsequently decays into pi(+)pi(-), is constructed in a factorization approach. In the S wave, we implement the strong decay R ->pi(+)pi(-) by means of a scalar form factor. This provides a unitary description of the pion-pion interaction in the entire kinematically allowed mass range m(pi pi)(2) from threshold to about 3 GeV2. In order to reproduce the experimental Dalitz plot for D+->pi(+)pi(-)pi(+), we include contributions beyond the S wave. For the P wave, dominated by the rho(770)(0), we use a Breit-Wigner description. Higher waves are accounted for by using the usual isobar prescription for the f(2)(1270) and rho(1450)(0). The major achievement is a good reproduction of the experimental m(pi pi)(2) distribution, and of the partial as well as the total D+->pi(+)pi(-)pi(+) branching ratios. Our values are generally smaller than the experimental ones. We discuss this shortcoming and, as a by-product, we predict a value for the poorly known D ->sigma transition form factor at q(2)=m pi(2).

DT Article
ID HYBRID MONTE-CARLO; LATTICE QCD; CONTINUUM-LIMIT; ROPER RESONANCE;
IMPROVEMENT; MODEL
AB Highly excited states for isospin 1/2 baryons are calculated for the first time using lattice QCD with two flavors of dynamical quarks. Anisotropic lattices are used with two pion masses, m(pi) = 416(36) MeV and 578(29) MeV. The lowest four energies are reported in each of the six irreducible representations of the octahedral group at each pion mass. The lattices used have dimensions 24(3) X 64, spatial lattice spacing a(s) approximate to 0.11 fm, and temporal lattice spacing a(t) = 1/3a(s). Clear evidence is found for a 5/2 state in the pattern of negative-parity excited states.

Both exclusive and inclusive cross sections are presented. We separately consider the cross section for jets containing a single b quark and jets containing a b (b) over bar pair. There are a wide variety of processes that contribute, and it is necessary to include them all in order to have a complete description at both colliders.

AB Two-body Dirac equations (TBDE) of Dirac's relativistic constraint dynamics have been successfully applied to obtain a covariant nonperturbative description of QED and QCD bound states. Coulomb-type potentials in these applications lead naively in other approaches to singular relativistic corrections at short distances that require the introduction of either perturbative treatments or smoothing parameters. We examine the corresponding singular structures in the effective potentials of the relativistic Schrodinger equation obtained from the Pauli reduction of the TBDE. We find that the relativistic Schrodinger equation leads in fact to well-behaved wave function solutions when the full potential and couplings of the system are taken into account. The most unusual case is the coupled triplet system with S=1 and L={(J-1),(J+1)}. Without the inclusion of the tensor coupling, the effective S-state potential would become attractively singular. We show how including the tensor coupling is essential in order that the wave functions be well-behaved at short distances. For example, the S-state wave function becomes simply proportional to the D-state wave function and dips sharply to zero at the origin, unlike the usual S-state wave functions. Furthermore, this behavior is similar in both QED and QCD, independent of the asymptotic freedom behavior of the assumed QCD vector potential. Light- and heavy-quark meson states can be described well by using a simplified linear-plus-Coulomb-type QCD potential apportioned appropriately between world scalar and vector potentials. We use this potential to exhibit explicitly the origin of the large pi-rho splitting and effective chiral symmetry breaking. The TBDE formalism developed here may be used to study quarkonia in quark-gluon plasma environments.

AB We formulate the Polyakov-Nambu-Jona-Lasinio model in 0 + 1 dimensions. The thermodynamics captured by the partition function yields a bulk pressure, as well as quark susceptibilities versus temperature that are similar to the ones in 3 + 1 dimensions. Around the transition temperature the behavior in the pressure and quark susceptibilities follows from the interplay between the lowest Matsubara frequency and the Polyakov line. The reduction to the lowest Matsubara frequency yields a matrix model. In the presence of the Polyakov line the UV part of the Dirac spectrum features oscillations when close to the transition temperature.

AB The trace anomaly of quantum fields in electromagnetic or gravitational backgrounds implies the existence of massless scalar poles in physical amplitudes involving the stress-energy tensor. Considering first the axial anomaly and using QED as an example, we compute the full one-loop triangle amplitude of the fermionic stress tensor with two current vertices, < T(mu nu)J(alpha)J(beta)>, and exhibit the scalar pole in this amplitude associated with the trace anomaly, in the limit of zero electron mass m -> 0. To emphasize the infrared aspect of the anomaly, we use a dispersive approach and show that this amplitude and the existence of the massless scalar pole is determined completely by its ultraviolet finite terms, together with the requirements of Poincare invariance of the vacuum, Bose symmetry under interchange of J(alpha) and J(beta), and vector current and stress-tensor conservation. We derive a sum rule for the appropriate positive spectral function corresponding to the discontinuity of the triangle amplitude, showing that it becomes proportional to delta(k(2)) and therefore contains a massless scalar intermediate state in the conformal limit of zero electron mass. The effective action corresponding to the trace of the triangle amplitude can be expressed in local form by the introduction of two scalar auxiliary fields which satisfy massless wave equations. These massless scalar degrees of freedom couple to classical sources, contribute to gravitational scattering processes, and can have long range gravitational effects.

AB We present the first light-hadron spectroscopy on a set of N(f)=2+1 dynamical, anisotropic lattices. A convenient set of coordinates that parameterize the two-dimensional plane of light and strange-quark masses is introduced. These coordinates are used to extrapolate data obtained at the simulated values of the quark masses to the physical light and strange-quark point. A measurement of the Sommer scale on these ensembles is made, and the performance of the hybrid Monte Carlo algorithm used for generating the ensembles is estimated.

AB We study the production of Mueller-Navelet jets at hadron colliders in the Balitsky-Fadin-Kuraev-Lipatov framework. We show that a measurement of the relative azimuthal angle Delta Phi between the jets can provide a good testing ground for corrections due to next-leading logarithms (NLL). Besides the well-known azimuthal decorrelation with increasing rapidity interval Delta eta between the jets, we propose to also measure this effect as a function of R=k(2)/k(1), the ratio between the jet transverse momenta. Using renormalization-group improved NLL kernel, we obtain predictions for d sigma/d Delta eta dRd Delta Phi. We analyze NLL-scheme and renormalization-scale uncertainties, and energy-momentum conservation effects, in order to motivate a measurement at the Tevatron and the LHC.

AB We present a molecular dynamics based method for accurately computing short-range structural forces resulting from the overlap of spatially diffuse solid-liquid interfaces at wetted grain boundaries close to the melting point. The method is based on monitoring the fluctuations of the liquid layer width at different temperatures to extract the excess interfacial free energy as a function of this width. The method is illustrated for a high-energy Sigma 9 twist boundary in pure Ni. The short-range repulsion driving premelting is found to be dominant in comparison to long-range dispersion and entropic forces and consistent with previous experimental findings that nanometer-scale layer widths may be observed only very close to the melting point.

AB Results of large scale nonequilibrium molecular dynamics simulations are presented for nanoparticles in an explicit solvent. The nanoparticles are modeled as a uniform distribution of Lennard-Jones particles, while the solvent is represented by standard Lennard-Jones particles. We present results for the shear rheology of spherical nanoparticles of diameter 10 times that of the solvent for a range of nanoparticle volume fractions. By varying the strength of the interactions between nanoparticles and with the solvent, this system can be used to model colloidal gels and glasses as well as hard spherelike nanoparticles. Effect of including the solvent explictly is demonstrated by comparing the pair correlation function of nanoparticles to that in an implicit solvent. The shear rheology for dumbbell nanoparticles made of two fused spheres is similar to that of single nanoparticle.

AB Nanosecond pulsed laser heating was used to control the assembly of spatially correlated nanoparticles from lithographically patterned pseudo-one-dimensional nickel lines. The evolution of the nickel line instabilities and nanoparticle formation with a correlated size and spacing was observed after a series of laser pulses. To understand the instabilities that direct the nanoparticle assembly, we have carried out nonlinear time-dependent simulations and linear stability analysis based on a simple hydrodynamic model. We find that the simulated time scales and length scales agree well with the experimental results. Interestingly, in both experiments and simulations, the instabilities associated with the line edge, and with the surface perturbation-driven mechanism, are found to result in similar particle sizes and spacings.

AB Polymer nanocomposites offer the potential to create a new type of hybrid material with unique thermal, optical, or electrical properties. Understanding their structure, phase behavior, and dynamics is crucial for realizing such potentials. In this work we provide an experimental insight into the dynamics of such composites in terms of the temperature, wave vector, and volume fraction of nanoparticles, using multispeckle synchrotron x-ray photon correlation spectroscopy measurements on gold nanoparticles embedded in polymethylmethacrylate. Detailed analysis of the intermediate scattering functions reveals possible existence of an intrinsic length scale for dynamic heterogeneity in polymer nanocomposites similar to that seen in other soft materials like colloidal gels and glasses.

AB The nOHFBBB1M7 (n=10) compound, 10OHF, shows a reversed SmC(FI2)(*)-SmC(*) phase sequence, unique among all known antiferroelectric liquid crystals. This reversed phase sequence is stabilized when 10OHF is doped with 9OTBBB1M7(C9) or 11OTBBB1M7(C11). In contrast, doping of the homologous members (n=9, 11, or 12) eliminates the SmC(FI2)(*) phase. One 10OHF/11OHF mixture without the SmC(FI2)(*) phase was selected for further studies. By adding C9 into this particular mixture, the reversed phase sequence is revived. To our surprise, even though 11OHF destabilizes the SmC(FI2)(*) phase in binary mixtures with 10OHF, it significantly increases the SmC(FI2)(*) temperature range in the 10OHF/11OHF/C9 ternary mixtures.

AB Recent advances in laser-plasma accelerators, including the generation of GeV-scale electron bunches, enable applications such as driving a compact free-electron laser (FEL). Significant reduction in size of the FEL is facilitated by the expected ultrahigh peak beam currents (10-100 kA) generated in laser-plasma accelerators. At low electron energies such peak currents are expected to cause space-charge effects such as bunch expansion and induced energy variations along the bunch, potentially hindering the FEL process. In this paper we discuss a self-consistent approach to modeling space-charge effects for the regime of laser-plasma-accelerated ultracompact electron bunches at low or moderate energies. Analytical treatments are considered as well as point-to-point particle simulations, including the beam transport from the laser-plasma accelerator through focusing devices and the undulator. In contradiction to non-self-consistent analyses (i.e., neglecting bunch evolution), which predict a linearly growing energy chirp, we have found the energy chirp reaches a maximum and decreases thereafter. The impact of the space-charge induced chirp on FEL performance is discussed and possible solutions are presented.

DT Article
AB A superconducting energy-recovery linac (ERL) is under construction at Brookhaven National Laboratory (BNL) to serve as a test bed for an application to upgrades of the Relativistic Heavy Ion Collider (RHIC). The damping of higher-order modes in the superconducting five-cell cavity is of paramount importance and represents the topic of this paper. Achieving the damping by the exclusive use of two ferrite absorbers and the adoption of a space-saving step instead of the conventional taper are part of the exploratory study. Absorber properties which are portable to simulation programs for the ERL cavity have been obtained by measuring the absorber as a ferrite-loaded pill-box cavity. Measured and simulated results for the lowest dipole modes in the prototype copper cavity with one absorber are discussed. First room-temperature measurements of the fully assembled niobium cavity string are presented which confirm the effective damping of higher-order modes by the ferrite absorbers, and which give credibility to the simulated R over Q's in the ERL.

AB A scheme of generating a uniform ellipsoidal laser pulse for high-brightness photoinjectors is discussed. The scheme is based on the chromatic aberration of a dispersive lens. Fourier optics simulation reveals the interplay of group velocity delay and dispersion in the scheme, as well as diffractions. Particle tracking simulation shows that the beam generated by such a laser pulse approaches the performance of that by an ideal ellipsoidal laser pulse and represents a significant improvement from the traditionally proposed cylindrical beam geometry. The scheme is tested in an 800-nm, optical proof-of-principle experiment at lower peak power with excellent agreement between the measurement and simulation.

AB Knowledge of the three-dimensional structure of a charged particle beam bunch is essential for understanding its evolution and for initializing computer simulations, especially when space charge is involved. This paper presents a novel experimental method for time-sliced mapping of the transverse phase space of a space-charge dominated beam based on tomographic principles. The combination of a high precision tomographic diagnostic with fast imaging screens and a gated camera are used to produce phase-space maps of two beams: one with a parabolic current profile and another with a short perturbation atop a rectangular pulse. The correlations between longitudinal and transverse phase spaces are apparent and their impact on the dynamics is discussed.

In addition, we study finite-thickness or double-interface A/B/A configurations such as air/SF(6)/air gas-curtain experiments. We first consider conventional shock tubes that have a "fixed" boundary: A solid endwall which reflects the transmitted shock and reshocks the interface(s). Then we focus on new experiments with a "free" boundary-a membrane disrupted mechanically or by the transmitted shock, sending back a rarefaction toward the interface(s). Complex acceleration histories are achieved, relevant for inertial confinement fusion implosions. We compare our simulation results with a generalized Layzer model for two fluids with time-dependent densities and derive a new freeze-out condition whereby accelerating and compressive forces cancel each other out. Except for the recently reported failures of the Layzer model, the generalized Layzer model and hydrocode simulations for reshocks and rarefactions agree well with each other and remain to be verified experimentally.

AB The maintenance of the magnetic configuration of a reversed field pinch (RFP) is an unsolved problem. Even a toroidal loop voltage does not suffice to maintain the magnetic configuration in axisymmetry but could if the plasma had helical shaping. The theoretical tools for plasma optimization using helical shaping have advanced, so a RFP could be relatively easily designed for optimal performance with a spatially constant toroidal loop voltage. A demonstration that interesting solutions exist is given.

AB Measurements of electron energy distributions from ultraintense (>10(19) W/cm(2)) laser solid interactions using an electron spectrometer are presented. The effective hot electron temperatures (T(hot)) have been measured for laser intensities (I lambda(2)) from 10(18) to 10(21) W/cm(2) mu m(2) for the first time, and T(hot) is found to increase as (I lambda(2))(0.34 +/- 0.04). This scaling agrees well with the empirical scaling published by Beg [Phys. Plasmas 4, 447 (1997)], and was modeled by particle-in-cell simulations.

AB By fielding several compact proton spectrometers at various locations around an ignition-capsule implosion at the National Ignition Facility [G. H. Miller, E. I. Moses, and C. R. Wuest, Nucl. Fusion 44, S228 (2004)], rho R and rho R asymmetries of the ablator for a failed implosion can be obtained through absolute measurements of knock-on proton (KO-P) spectra. For ignition capsules with a Cu-doped beryllium (Be) ablator, 50:50 mixture of deuterium-tritium (DT) fuel and similar to 1% residual hydrogen (H) by atom, failed implosions can be diagnosed for neutron yields ranging from similar to 10(11) to similar to 6x10(15) and local rho Rs up to similar to 240 mg/cm(2). For capsules with an ablator of Ge-doped CH, which contains a large amounts of H, failed implosions can be diagnosed for neutron yields ranging from similar to 10(10) to similar to 6x10(15) and local rho Rs up to similar to 200 mg/cm(2). Prior to the first ignition experiments, capsules with a Cu-doped Be ablator (or Ge-doped CH ablator), more deuterium-lean fuel mixture and H-dopant levels up to 25% in the fuel will be imploded to primarily reduce the neutron yield. The HDT-filled Be-capsule implosion, which can be diagnosed for neutron yields ranging from similar to 5x10(9) to similar to 6x10(15) and local rho Rs up to similar to 240 mg/cm(2), is more suitable to diagnose using KO-Ps as the signal-to-background ratio is significantly higher than for an ignition-capsule implosion. In addition, analysis of CH-ablator data obtained from analogous OMEGA [T. R. Boehly, D. L. Brown, R. S. Craxton , Opt. Commun. 133, 495 (1997)] experiments indicate that the shape of the KO-P spectrum is affected mainly by the ablator rho R. Other effects such as ablator-density-profile variations, time evolution of the ablator rho R, fuel-ablator mix and electron temperature variations typically predicted for the ablator play minor roles.

AB An energy conserving set of the fully electromagnetic nonlinear gyrokinetic Vlasov equation and Maxwell's equations, which is applicable to both L-mode turbulence with large amplitude and H-mode turbulence in the presence of high ExB shear has been derived. The phase-space action variational Lie perturbation method ensures the preservation of the conservation laws of the underlying Vlasov-Maxwell system. Generalized ordering takes rho(i) N-DEP. The C- and A-DEP/OVA exposure groups had significant increases in eosinophils, OVA-specific IgG1, and airway hyperresponsiveness. In addition, the C-DEP/OVA exposure increased the T helper 2 (T(H)2) chemoattractant chemokine, thymus and activation-regulated chemokine and exhibited the most severe perivascular inflammation in the lung, whereas A-DEP/OVA increased interleukin (IL)-5 and IL-10. In contrast, N-DEP/OVA exposure only increased OVA-specific IgG1 post-challenge. Analysis of early signaling showed that C-DEP induced a greater number of T(H)2 cytokines compared with A-DEP and N-DEP. The results suggest that potentiation of allergic immune responses by DEP is associated with PAH content rather than the total amount of EOM.

AB Concerns about the potential adverse health effects of engineered nanoparticles stems in part from the possibility that some materials display unique chemical and physical properties at nanoscales which could exacerbate their biological activity. However, studies that have assessed the effect of particle size across a comprehensive set of biological responses have not been reported. Using a macrophage cell model, we demonstrate that the ability of unopsonized amorphous silica particles to stimulate inflammatory protein secretion and induce macrophage cytotoxicity scales closely with the total administered particle surface area across a wide range of particle diameters (7-500 nm). Whole genome microarray analysis of the early gene expression changes induced by 10- and 500-nm particles showed that the magnitude of change for the majority of genes affected correlated more tightly with particle surface area than either particle mass or number. Gene expression changes that were particle size-specific were also identified. However, the overall biological processes represented by all gene expression changes were nearly identical, irrespective of particle diameter. Direct comparison of the cell processes represented in the 10- and 500-nm particle gene sets using gene set enrichment analysis revealed that among 1009 total biological processes, none were statistically enriched in one particle size group over the other. The key mechanisms involved in silica nanoparticle-mediated gene regulation and cytotoxicity have yet to be established. However, our results suggest that on an equivalent nominal surface area basis, common biological modes of action are expected for nano- and supranano-sized silica particles.

AB We seek simple analytical solutions in a model of gas flow driven by a combination of buoyancy, viscous, and capillary forces. Traveling-wave solutions describe propagation of the top and bottom of the gas plume. The top of the plume has low gas saturation, but propagates much faster than the bottom. The theoretical maximum of the velocity of propagation of the top of the plume provides a simple conservative estimate of the time until plume evolution will dramatically slow down. A sequence of rarefaction and traveling-wave solutions characterizes the transition zones between the top and bottom stable regions. The analytical results are applied to studying carbon dioxide flow caused by leaks from deep geological formations used for CO(2) storage. The results are also applicable for modeling flow of natural gas leaking from seasonal gas storage, or for modeling of secondary hydrocarbon migration.

AB DNA fabrication of genetic cassettes at base-level precision is transforming genetic engineering from a laborious art to an information-driven discipline. Although substantial advances have been made in the development of DNA fabrication, the methods employed vary widely based on the length of the DNA. All of these methods are available commercially, but can also be performed at the molecular biology bench using typical reagents and procedures. Because the technology is not mature and is still evolving rapidly, it is helpful to gain some understanding of the different steps in this process and the associated technical challenges to successfully take advantage of DNA fabrication in a research project.

AB Infection is often referred to as a race between pathogen and immune response. This metaphor suggests that slower growing pathogens should be more easily controlled. However, a growing body of evidence shows that many chronic infections are caused by failure to control slow growing pathogens. The slow growth of pathogens seems to directly affect the kinetics of the immune response. Compared with the response to fast growing pathogens, the T-cell response to slow pathogens is delayed in its initiation, lymphocyte expansion is slow and the response often fails to clear the pathogen, leading to chronic infection. Understanding the 'rules of the race' for slow growing pathogens has important implications for vaccine design and immune control of many chronic infections.

AB Nanoscale confinement of the magnetization in a magnetic element often results in the creation of a vortex structure. The vortex equilibrium state is characterized by the curling of the in-plane magnetization (chirality) and an out-of-plane core magnetization. The polarity of the vortex core can point up or down, independent of the chirality, and, thus, magnetic elements with a vortex core are interesting as four-state logic elements. We present an easy-to-use, quantitative method for the determination of both chirality and polarity from a single Fresnel image. This method offers direct evidence of the three-dimensional structure of a magnetic vortex and has significant advantages over the more complex methods currently in use. (C) 2008 Elsevier B.V.

TI Limitations in Determining Multifractal Spectra from Pore-Solid Soil
Aggregate Images
SO VADOSE ZONE JOURNAL
LA English
DT Article
ID RAY COMPUTED-TOMOGRAPHY; FRACTAL DIMENSION
AB Multifractal methods have the potential to be useful tools for characterizing spatial distributions of soil pores from microtomographic images of undisturbed soil cores and soil aggregates. The objective of this study was to examine the limitations of multifractal analyses in binary (void and solid) soil images and to explore conditions under which multifractal spectra can be obtained. Multifractal characteristics of binary soil images are bounded within certain limiting values corresponding to nonfractal scaling. In this study, we first addressed the theoretical limitations of multifractal analysis of binary images and examined the nonfractal scaling boundaries in multifractal calculations by the method of moments. Then we developed boundary conditions for multifractal calculations by the direct method. Results revealed that fractal scaling is potentially possible only across a relatively narrow range of cell sizes restricted by the nonfractal scaling boundaries. Moreover, the range of cell sizes where fractal scaling is potentially possible varies with pore size. That is, in multifractal calculations it changes continuously with changes in the q value. For the soil aggregates examined in this study, this range varied from two to eight pixels for low q values to 128 pixels for high q values. The varying range makes calculations of true multifractal spectra for binary soil image data impossible. These results are consistent with a general theoretical notion that binary soil images are not multifractal in a strict mathematical sense. We suggest, however, that application of multifractal formalism can generate "pseudo-multifractal spectra" that might still be useful for summarizing pore distribution information and for comparing pore data among different agricultural management regimes and soil types.

AB Biodegradation of N-Nitrosodimethylamine (NDMA) has been found through laboratory incubation in unsaturated and saturated soil samples under both aerobic and anaerobic conditions. However, direct field evidence of in situ biodegradation in groundwater is very limited. This research aimed to evaluate biodegradation of NDMA in a large-scale groundwater system receiving recycled water as incidental and active recharge. NDMA concentrations in 32 monitoring and production wells with different screen intervals were monitored over a period of seven years. Groundwater monitoring was used to characterize changes in the magnitude and extent of NDMA in groundwater in response to seasonal hydrogeologic conditions and, more importantly, to significant concentration variations in effluent from water reclamation plants (associated with treatment-process changes). Extensive monitoring of NDMA concentrations and flow rates at effluent discharge locations and surface-water stations was also conducted to reasonably estimate mass loading through unlined river reaches to underlying groundwater. Monitoring results indicate that significant biodegradation of NDMA occur-red in groundwater, accounting for an estimated 90% mass reduction over the seven-year monitoring period. In addition, a discrete effluent-discharge and groundwater-extraction event was extensively monitored in a well-characterized, localized groundwater subsystem for 626 days. Analysis of the associated NDMA fate and transport in the subsystem indicated that an estimated 80% of the recharged mass was biodegraded. The observed field evidence of NDMA biodegradation is supported by groundwater transport modeling accounting for various dilution mechanisms and first-order decay for biodegradation, and by a previous laboratory study on soil samples collected from the study site [Bradley, P.M., Carr, S.A., Baird, R.B., Chapelle, F.H., 2005.

AB Ta and Ta-1% W are being considered to be used as target clad materials in the LANSCE proton beam line for the material test station (MTS). To Investigate the embrittlement of these materials due to oxygen contamination and proton irradiation, Ta and Ta-1 wt% W (as received and with similar to 400 ppm O) were exposed to a 3.5 MeV proton beam at the ion beam materials laboratory at LANL. After irradiating the samples in the proton beam, nanoindentation was performed in cross-section to investigate the hardness increase of the materials due to irradiation. The nanoindentation showed that the hardness increase due to irradiation is between 9% and 20% depending on the material. The results show good agreement with mechanical testing results on tantalum and Ta-1 wt% W after high energy proton irradiation to doses up to 23 dpa. Published by Elsevier B.V.

AB Surface passivation of device-grade CdZnTe was investigated using X-ray photoelectron spectroscopy in combination with transport property measurements after Br-MeOH (2% Br) and KOH/NR(4)F/H(2)O(2) solutions were used to etch and oxidize the surface. High-resolution photoemission measurements on the valence band electronic structure and core lines were used to evaluate the surface chemistry of the chemically treated surfaces. Metal overlayers were then deposited on these chemically treated surfaces and the I-V characteristics measured. The measurements were correlated to understand the effect of interface chemistry on the electronic structure at these interfaces with the goal of optimizing the Schottky barrier height for radiation detector devices.

AB Partial oxidation of methane into syngas was conducted over fresh and sulfided catalysts at a temperature range of 450-750 degrees C. The temperature dependence of conversion, H(2)/CO ratio, and the CO(2) concentration were measured for both fresh and sulfided catalysts. Regardless of metal type, metal loading, support type, and the methods of preparation it appears that all the fresh catalysts were very active and conversions of higher than 70% with H(2)/CO ratio of about 2 were observed at 750 degrees C. Pulse sulfidation appears to be reversible for some of the catalysts but not for all. Under pulse sulfidation conditions, the Rh(0.5%)/Al(2)O(3) and NiMg(2)O(x)-1100 degrees C (solid solution) catalysts were fully regenerated after reduction with hydrogen. Rh catalyst showed the best overall activity, less carbon deposition, both fresh and when it was exposed to pulses of H(2)S. Sulfidation under steady-state conditions, flowing H(2)S/Ar mixture over the catalysts, significantly reduce catalyst activity. The catalysts were characterized before and after reaction with H2S using temperature-programmed oxidation (TPO) and reduction (TPR), X-ray diffraction, and XPS. (C) 2008 Published by Elsevier B.V.

AB Production of hydrogen by splitting of water in the thermochemical sulfur-based cycles that employs the catalytic decomposition of sulfuric acid into SO(2) and O(2) is of considerable interest. However, all of the known catalytic systems studied to date that consist of metal particles on oxide substrates deactivate with time on stream. To develop an understanding of the factors that are responsible for catalyst activity, we investigate the fresh activity of several platinum group metals (PGM) catalysts, including Pd, Pt, Rh, Ir, and Ru supported on titania at 850 degrees C and perform an extensive theoretical study (density-functional-theory-based first-principles calculations and computer simulations) of the activity of the PGM nanoparticles of different size and shape positioned on TiO(2) (rutile and anatase) and Al(2)O(3) (gamma- and eta-alumina) surfaces. The activity and deactivation of the catalytic systems are defined by (i) the energy barrier for the detachment of O atoms from the SO(n) (n = 1, 2, 3) species, and (ii) the removal rate of the products of the sulfuric acid decomposition (atomic O, S, and the SO(n) species) from metal nanoparticles. We show that these two nanoscale features collectively result in the observed experimental behavior. The removal rate of the reaction products is always lower than the SOn decomposition rates. The relation between these two rates explains why the "softer" PGM nanoparticles (Pd and Pt) exhibit the highest initial catalytic activity. (C) 2008 Elsevier B.V. All rights reserved.

AB Batch reactor experiments were conducted to assess perthitic alkali-feldspar dissolution and secondary mineral formation in an initially acidic fluid (pH=3.1) at 200 degrees C and 300 bars. Temporal evolution of fluid chemistry was monitored by major element analysis of in situ fluid samples. Solid reaction products were retrieved from two identical experiments terminated after 5 and 78 days. Scanning electron microscopy revealed dissolution features and significant secondary mineral coverage on feldspar surfaces. Boehmite and kaolinite were identified as secondary minerals by X-ray diffraction and transmission electron microscopy. Xray photoelectron spectroscopy analysis of alkali-feldspar surfaces before and after reaction showed a trend of increasing Al/Si ratios and decreasing K/Al ratios with reaction progress, consistent with the formation of boehmite and kaolinite.
Saturation indices of feldspars and secondary minerals suggest that albite dissolution occurred throughout the experiments, while K-fieldspar exceeded saturation after 216 h of reaction. Reactions proceeded slowly and full equilibrium was not achieved, the relatively high temperature of the experiments notwithstanding. Thus, time series observations indicate continuous supersaturation with respect to boehmite and kaolinite, although the extent of this decreased with reaction progress as the driving force for albite dissolution decreased. The first experimental evidence of metastable co-existence of boehmite, kaolinite and alkali feldspar in the feldspar hydrolysis system is consistent with theoretical models of mineral dissolution/precipitation kinetics where the ratio of the secondary mineral precipitation rate constant to the rate constant of feldspar dissolution is well below unity. This has important implications for modeling the time-dependent evolution of feldspar dissolution and secondary mineral formation in natural systems. (C) 2008 Elsevier B.V. All rights reserved.

AB Background: Ecological niche modeling is a method for estimation of species distributions based on certain ecological parameters. Thus far, empirical determination of significant differences between independently generated distribution maps for a single species (maps which are created through equivalent processes, but with different ecological input parameters), has been challenging.
Results: We describe a method for comparing model outcomes, which allows a statistical evaluation of whether the strength of prediction and breadth of predicted areas is measurably different between projected distributions. To create ecological niche models for statistical comparison, we utilized GARP (Genetic Algorithm for Rule-Set Production) software to generate ecological niche models of human monkeypox in Africa. We created several models, keeping constant the case location input records for each model but varying the ecological input data. In order to assess the relative importance of each ecological parameter included in the development of the individual predicted distributions, we performed pixel-to-pixel comparisons between model outcomes and calculated the mean difference in pixel scores. We used a two sample Student's t-test, (assuming as null hypothesis that both maps were identical to each other regardless of which input parameters were used) to examine whether the mean difference in corresponding pixel scores from one map to another was greater than would be expected by chance alone. We also utilized weighted kappa statistics, frequency distributions, and percent difference to look at the disparities in pixel scores. Multiple independent statistical tests indicated precipitation as the single most important independent ecological parameter in the niche model for human monkeypox disease.
Conclusion: In addition to improving our understanding of the natural factors influencing the distribution of human monkeypox disease, such pixel-to-pixel comparison tests afford users the ability to empirically distinguish the significance of each of the diverse environmental parameters included in the modeling process. This method will be particularly useful in situations where the outcomes (maps) appear similar upon visual inspection (as are generated with other modeling programs such as MAXENT), as it allows an investigator the capacity to explore subtle differences among ecological parameters and to demonstrate the individual importance of these factors within an overall model.

AB The extracted s-wave scattering amplitude from both the polarized and unpolarized d + d -> (4)He + eta reaction at 2385.5 MeV/c allowed to determine the scattering length which fulfills the requirements for bound eta. In the p + (27)Al -> (3)He + p + pi(-) + X reaction studied at recoil free kinematics the eta meson is produced almost at rest and so it can be bound with enhanced probability. This state proceeds via N*(1535) resonance and the decay products proton and pion emitted into opposite direction are detected in concidence with (3)He produced at zero degree. Under these conditions some hints for bound state can be observed with an upper limit of the cross section of approximate to 0.5 nb.

AB Theoretical calculations predict the modi. cation of properties of vector mesons, such as a shift in their masses and/or broadening of their widths in dense nuclear matter. These effects can be related to partial restoration of chiral symmetry at high density or temperature. The light vector mesons (rho, omega, and phi) were photo-produced on (2)H, C, Ti, Fe, and Pb targets at the Thomas Jefferson National Laboratory using the CEBAF Large Acceptance Spectrometer (CLAS). The data were taken with a beam of tagged photons with energies up to 4 GeV. The properties of the rho vector meson at normal nuclear densities and zero temperature, were investigated via their rare leptonic decay to e(+)e(-). This decay channel is preferred over hadronic modes in order to eliminate final state interactions in the nuclear matter. A combinatorial background was subtracted from the invariant mass spectra using a well-established event-mixing technique. The rho meson mass spectrum was extracted after the omega and phi signals were removed in a nearly model-independent way. The rho meson mass distributions were extracted for each of the targets. Comparisons were made between the rho mass spectra from the heavy targets (A > 2) with the mass spectrum extracted from the deuterium target. With respect to the rho-meson mass, we obtain a small shift compatible with zero. Also, we measure widths consistent with standard nuclear many-body effects such as collisional broadening and Fermi motion.
In this experiment, due to the long lifetimes and momenta greater than 0.8 GeV, the omega and phi mesons have a high probability of decaying outside the nucleus in their vacuum state. However, their in-medium widths can be accessed through their absorption inside the nucleus. Preliminary results on the ratios of the nuclear transparencies of the omega and phi mesons as a function of the number of target nucleons A, have been obtained and indicate a substantial widening in the medium.

AB Energy-dependent quenching of excitons in photosystem II of plants, or qE, has been positively correlated with the transient production of carotenoid radical cation species. Zeaxanthin was shown to be the donor species in the CP29 antenna complex. We report transient absorbance analyses of CP24 and CP26 complexes that bind lutein and zeaxanthin in the L1 and L2 domains, respectively. For CP24 complexes, the transient absorbance difference profiles give a reconstructed transient absorbance spectrum with a single peak centered at similar to 980 nm, consistent with zeaxanthin radical cation formation. In contrast, CP26 gives constants for the decay components probed at 940 and 980 nm of 144 and 194 ps, a transient absorbance spectrum that has a main peak at 980 nm, and a substantial shoulder at 940 nm. This suggests the presence of two charge transfer quenching sites in CP26 involving zeaxanthin radical cation and lutein radical cation species. Wealso show that lutein radical cation formation in CP26 is dependent on binding of zeaxanthin to the L2 domain, implying that zeaxanthin acts as an allosteric effector of charge transfer quenching involving lutein in the L1 domain.

AB We report evidence that adenylate kinase (AK) from Escherichia coli can be activated by the direct binding of a magnesium ion to the enzyme, in addition to ATP-complexed Mg2+. By systematically varying the concentrations of AMP, ATP, and magnesium in kinetic experiments, we found that the apparent substrate inhibition of AK, formerly attributed to AMP, was suppressed at low magnesium concentrations and enhanced at high magnesium concentrations. This previously unreported magnesium dependence can be accounted for by a modified random bi-bi model in which Mg2+ can bind to AK directly prior to AMP binding. A new kinetic model is proposed to replace the conventional random bi-bi mechanism with substrate inhibition and is able to describe the kinetic data over a physiologically relevant range of magnesium concentrations. According to this model, the magnesium-activated AK exhibits a 23- +/- 3-fold increase in its forward reaction rate compared with the unactivated form. The findings imply that Mg2+ could be an important affecter in the energy signaling network in cells.

AB The effect of solvent viscosity mismatch on elution performance in reversed-phase HPLC was studied using moment analysis. Two conditions were tested: (1) the mobile phase viscosity was less than the injection plug viscosity, and (2) the mobile phase viscosity was greater than the injection plug viscosity. Under the first condition, retention time and elution performance decreased as the viscosity contrast between the mobile phase and injection plug increased. The effect on performance was more marked as the injection volume increased. A decrease in performance of 12% for compounds with retention factors up to 2.8 was apparent even when the viscosity contrast was only 0.165 cP. In the second set of conditions, elution performance was actually observed to increase, by as much as 25% for a 40 mu L injection, as the viscosity contrast between the mobile phase and the solute plug increased. No change in the retention factor was observed. This behaviour was attributed to the shape of an injection plug as it enters into the column, whereby a low viscosity plug permeates away from the wall when the column contains a higher viscosity mobile phase, and vice a versa for a high viscosity plug entering a low viscosity mobile phase. At no stage was either a band splitting or shoulders observed with viscosity contrasts up to 1.283 cP, as could have been expected. (C) 2008 Elsevier B.V. All rights reserved.

AB In a free electron laser (FEL), the electron bunch energy profile at the undulator entrance can have temporal structures. In this paper, we derive the FEL Green's function for the case of the electron bunch having both energy chirp and energy curvature by solving the coupled Vlasov-Maxwell equations. We give an integral representation as well as an analytic expression for the Green's function. The analytical expression is compared with direct numerical results. Evolution of the Green's function temporal duration and the frequency bandwidth are studied.

AB In addition to RNA polymerases I, II, and III, the essential RNA polymerases present in all eukaryotes, plants have two additional nuclear RNA polymerases, abbreviated as Pol IV and Pol V, that play nonredundant roles in siRNA-directed DNA methylation and gene silencing. We show that Arabidopsis Pol IV and Pol V are composed of subunits that are paralogous or identical to the 12 subunits of Pol II. Four subunits of Pol IV are distinct from their Pol II paralogs, six subunits of Pol V are distinct from their Pol II paralogs, and four subunits differ between Pol IV and Pol V. Importantly, the subunit differences occur in key positions relative to the template entry and RNA exit paths. Our findings support the hypothesis that Pol IV and Pol V are Pol II-like enzymes that evolved specialized roles in the production of noncoding transcripts for RNA silencing and genome defense.

TI Direct Bound on the Total Decay Width of the Top Quark in p(p)over-bar
Collisions at root s=1.96 TeV
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID PHYSICS
AB We present the first direct experimental bound on the total decay width of the top quark, Gamma(t), using 955 pb(-1) of the Tevatron's p (p) over bar collisions recorded by the Collider Detector at Fermilab. We identify 253 top-antitop pair candidate events. The distribution of reconstructed top quark mass from these events is fitted to templates representing different values of the top quark width. Using a confidence interval based on likelihood-ratio ordering, we extract an upper limit at 95% C.L. of Gamma(t) < 13.1 GeV for an assumed top quark mass of 175 GeV/c(2).

TI Search for Maximal Flavor Violating Scalars in Same-Charge Lepton Pairs
in p(p)over-bar Collisions at root s=1.96 TeV
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
AB Models of maximal flavor violation (MxFV) in elementary particle physics may contain at least one new scalar SU(2) doublet field phi(FV) = (eta(0),eta(+)) that couples the first and third generation quarks (q(1), q(3)) via a Lagrangian term L-FV = xi(13)phi(FV)q(1)q(3). These models have a distinctive signature of same-charge top-quark pairs and evade flavor-changing limits from meson mixing measurements. Data corresponding to 2 fb(-1) collected by the Collider Dectector at Fermilab II detector in p (p) over bar collisions at root s = 1.96 TeV are analyzed for evidence of the MxFV signature. For a neutral scalar eta(0) with m(eta 0) = 200 GeV/c(2) and coupling xi(13) = 1, similar to 11 signal events are expected over a background of 2.1 +/- 1.8 events. Three events are observed in the data, consistent with background expectations, and limits are set on the coupling xi(13) for m(eta 0) = 180-300 GeV/c(2).

ID MAGNETRON; DISCHARGES
AB When self-sputtering is driven far above the runaway threshold voltage, energetic electrons are made available to produce "excess plasma" far from the magnetron target. Ionization balance considerations show that the secondary electrons deliver the necessary energy to the "remote" zone. Thereby, such a system can be an extraordinarily prolific generator of usable metal ions. Contrary to other known sources, the ion current to a substrate can exceed the discharge current. For gasless self-sputtering of copper, the usable ion current scales exponentially with the discharge voltage.

TI Deep Subwavelength Terahertz Waveguides Using Gap Magnetic Plasmon
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID METAMATERIALS
AB We propose a novel subwavelength terahertz (THz) waveguide based on the magnetic plasmon polariton mode guided by a narrow gap in a negative permeability metamaterial. Deep subwavelength waveguiding (= 300, form a valuable laboratory in which to explore the control and manipulation of quantum states of mesoscopic size using carefully tailored sequences of short electric field pulses whose characteristic times (duration and/or rise/fall times) are less than the classical electron orbital period. Atoms react to such pulse sequences very differently than to short laser or microwave pulses providing the foundation for a number of new approaches to engineering atomic wavefunctions. The remarkable level of control that can be achieved is illustrated with reference to the generation of localized wavepackets in Bohr-like near-circular orbits, and the production of non-dispersive wavepackets under periodic driving and their transport to targeted regions of phase space. The testing of these control schemes, together with their reversibility, through the creation of electric dipole echoes in Stark wavepackets, is also described. New protocols continue to be developed that will allow even tighter control with the promise of new insights into quantum-classical correspondence, information storage in mesoscopic systems, physics in the ultra-fast ultra-intense regime and nonlinear dynamics in driven systems.

AB A basic introduction to the theory underlying x-ray processes is provided. After general remarks on the practical advantages of using x-rays for probing matter, the derivation of the minimal-coupling Hamiltonian within nonrelativistic quantum electrodynamics is outlined. Perturbation theory is reviewed and applied to describe x-ray-induced processes. In connection with x-ray absorption, inner-shell binding energies and the photon energy dependence of the x-ray absorption cross section are discussed. In the context of x-ray scattering, atomic and molecular scattering factors are introduced, the complex index of refraction is derived, and the nonrelativistic theory of Compton scattering is described. The final topic is x-ray fluorescence and Auger decay of inner-shell-excited systems.

TI Atomic lifetime measurements on forbidden transitions of Al-, Si-, P-

AB Lifetimes of 3s(2)3p(k) ground configuration levels of Al-, Si-, P- and S-like ions of Fe, Co and Ni have been measured at a heavy-ion storage ring. Some of the observed decay curves show strong evidence of cascade repopulation from specific 3d levels that feature lifetimes in the same multi-millisecond range as the levels of the ground configuration. We identify the foil-stripping process in the ion production as the cause of the cascade level population and assess the importance of specific cascades for the measurement technique.

AB We apply to transition metal monoxides the self-interaction corrected (SIC) local spin density approximation, implemented locally in the multiple scattering theory within the Korringa-Kohn-Rostoker (KKR) band structure method. The calculated electronic structure and in particular magnetic moments and energy gaps are discussed in reference to the earlier SIC results obtained within the linear muffin-tin orbital atomic sphere approximation band structure method, involving transformations between Bloch and Wannier representations, in order to solve the eigenvalue problem and calculate the SIC charge and potential. Since the KKR method can be easily extended to treat disordered alloys, by invoking the coherent potential approximation (CPA), in this paper we compare the CPA approach and supercell calculations to study the electronic structure of NiO with cation vacancies.

TI First-principles study of fission product (Xe, Cs, Sr) incorporation and

interface
SO JOURNAL OF PHYSICS-CONDENSED MATTER
LA English
DT Article
ID DEFECT ENERGETICS; DYNAMICS; ENERGY
AB In order to close the nuclear fuel cycle, advanced concepts for separating out fission products are necessary. One approach is to use a dispersion fuel form in which a fissile core is surrounded by an inert matrix that captures and immobilizes the fission products from the core. If this inert matrix can be easily separated from the fuel, via e. g. solution chemistry, the fission products can be separated from the fissile material. We examine a surrogate dispersion fuel composition, in which hafnia (HfO2) is a surrogate for the fissile core and alkaline earth metal oxides are used as the inert matrix. The questions of fission product incorporation in these oxides and possible segregation behavior at interfaces are considered. Density functional theory based calculations for fission product elements (Xe, Sr, and Cs) in these oxides are carried out. We find smaller incorporation energy in hafnia than in MgO for Cs and Sr, and Xe if variation of charge state is allowed. We also find that this trend is reversed or reduced for alkaline earth metal oxides with large cation sizes. Model interfacial calculations show a strong tendency of segregation from bulk MgO to MgO-HfO2 interfaces.

AB We report the discovery that boron nitride nanotubes (BNNTs), isosteres of CNTs with unique physical properties, are inherently noncytotoxic. Furthermore, we developed a biomemetic coating strategy to interface BNNTs with proteins and cells. Finally, we showed that BNNTs can deliver DNA oligomers to the interior of cells with no apparent toxicity. This work suggests that BNNTs may be superior to CNTs for use as biological probes and in biomaterials.

SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY
LA English

ID ELECTRON-TRANSFER; N-METHYL-4-PICOLINIUM ESTERS; LIFE
AB We report the use of photoinduced electron transfer to drive reductive cleavage of an ester to produce bilayer-forming molecules; specifically, visible photolysis in a mixture of a decanoic acid ester precursor, hydrogen donor molecules, and a ruthenium-based photocatalyst that employs a linked nucteobase (8-oxo-guanine) as an electron donor generates decanoic acid. The overall transformation of the ester precursor to yield vesicles represents the use of an external energy source to convert nonstructure forming molecules into amphiphites that spontaneously assemble into vesicles. The core of our chemical reaction system uses an 8-oxo-G-Ru photocatalyst, a derivative of [tris(2,2'bipyridine)-Ru(II)](2+).

MASS-SPECTROMETRY
AB The reactions of the methylidyne radical (CH) with ethylene, acetylene, allene, and methylacetylene are studied at room temperature using tunable vacuum ultraviolet (VUV) photoionization and time-resolved mass spectrometry. The CH radicals are prepared by 248 nm multiphoton photolysis of CHBr(3) at 298 K and react with the selected hydrocarbon in a helium gas flow. Analysis of photoionization efficiency versus VUV photon wavelength permits isomer-specific detection of the reaction products and allows estimation of the reaction product branching ratios. The reactions proceed by either CH insertion or addition followed by H atom elimination from the intermediate adduct. In the CH + C(2)H(4) reaction the CA intermediate decays by H atom loss to yield 70(+/- 8)% allene, 30(+/- 8)% methylacetylene, and less than 10% cyclopropene, in agreement with previous RRKM results. In the CH + acetylene reaction, detection of mainly the cyclic C(3)H(2) isomer is contrary to a previous RRKM calculations that predicted linear triplet propargylene to be 90% of the total H-atom coproducts. High-level CBS-APNO quantum calculations and RRKM calculations for the CH + C(2)H(2) reaction presented in this manuscript predict a higher contribution of the Cyclic C(3)H(2) (27.0%) versus triplet propargylene (63.5%) than earlier predictions. Extensive calculations on the CA and CAD system combined with experimental isotope ratios for the CD + C(2)H(2) reaction indicate that H-atom-assisted isomerization in the present experiments is responsible for the remaining discrepancy between the new RRKM calculations and the experimental results. Cyclic isomers are also found to represent 30(+/- 6)% of the detected products in the case of CH + methylacetylene, together with 33(+/- 6)% 1,2,3-butatriene and 37(+/- 6)% vinylacetylene. The CH + allene reaction gives 23(+/- 5)% 1,2,3-butatriene and 77(+/- 5)% vinylacetylene, whereas cyclic isomers are produced below the detection limit in this reaction. The reaction exit channels deduced by comparing the product distributions for the aforementioned reactions are discussed in detail.

TI The Oil-Water Interface: Mapping the Solvation Potential
SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY

DT Article
ID SOFT-LANDED IONS; SURFACE
AB An ion moving across an oil-water interface experiences strong solvation changes. We have directly measured the solvation potential from 0.4 to 4 nm for Cs(+) ions approaching the oil-water interface from the oil side ("oil" = 3-methylpentane). The interfaces were built at 30 K using molecular beam epitaxy. Ions were precisely placed within the film during its growth using a soft-landing ion beam. The ion's collective electric field was progressively increased (by adding more ions) until it balanced the individual ion's solvation potential slope. As the samples were slowly warmed, near 90 K the ions began moving, as measured by a Kelvin probe. Their motion precisely determines the local slope of the solvation potential, which was integrated to get the potential. The potential is Born-like for z > 0.4 nm away from the oil-water interface. Our method could provide important tests of theoretical estimates of ion motion at biological interfaces and in atmospheric aerosols.

AB We study the interfacial behavior between the straight-chain alkyl surfactant sodium dodecyl sulfate (SDS) and single-walled carbon nanotubes (SWNTs) as a function of added electrolytes, including NaCl. We observe an increase in photoluminescence intensity and narrowing of spectral line widths with electrolyte addition, indicating a change in SDS aggregation number that leads to a pronounced volume change in the nanotube/SDS composite structure. By tuning the interfacial dynamics through NaCl addition and temperature change, we demonstrate that this volume change can be used to yield diameter-dependent separation of metallic and semiconducting SWNTs, without the use of any additional cosurfactant, through density gradient ultracentrifugation. The diameter-dependent fractionation follows the intrinsic relation expected for the density of unfunctionalized nanotubes, indicating a simple amplification of these inherent density differences as the mechanism for salt enhanced separations. Isolation of enriched metallic and semiconducting fractions further illustrates that the surface aggregation characteristics of SDS on metallic SWNTs are different from that on the semiconducting chiralities. These experiments illustrate the governing behavior of surface phenomena and interfacial forces on the diameter-dependent fractionation of SWNTs and point to new routes for enhancing existing separations strategies.

AB Deprotonation of tyrosine in the gas phase was found to occur preferentially at the phenolic site, and the conjugate base consists of a 70:30 mixture of phenoxide and carboxylate anions at equilibrium. This result was established by developing a chemical probe for differentiating these two isomers, and the presence of both ions was confirmed by photoelectron spectroscopy. Equilibrium acidity measurements on tyrosine indicated that Delta G(acid)degrees = 332.5 +/- 1.5 kcal mol(-1) and Delta H(acid)degrees = 340.7 +/- 1.5 kcal mol(-1). Photoelectron spectra yielded adiabatic electron detachment energies of 2.70 +/- 0.05 and 3.55 +/- 0.10 eV for the phenoxide and carboxylate anions, respectively. The H/D exchange behavior of deprotonated tyrosine was examined using three different alcohols (CF(3)CH(2)OD, C(6)H(5)CH(2)OD, and CH(3)CH(2)OD), and incorporation of up to three deuterium atoms was observed. Two pathways are proposed to account for these results, and all of the experimental findings are supplemented with B3LYP/aug-cc-pVDZ and G3B3 calculations. In addition, it was found that electrospray ionization of tyrosine from a 3:1 (v/v) CH(3)OH/H(2)O solution using a commercial source produces a deprotonated [M - H](-) anion with the gas-phase equilibrium composition rather than the structure of the ion that exists in aqueous media. Electrospray ionization from acetonitrile, however, leads largely to the liquid-phase (carboxylate) structure. A control molecule, p-hydroxybenzoic acid, was found to behave in a similar manner. Thus, the electrospray conditions that are employed for the analysis of a compound can alter the isomeric composition of the resulting anion.

AB We have prepared two series of first-generation thiophene-bridge dendrimers, with either three (3G1) or four (4G1) arms attached to a phenyl core, to elucidate their structure-property relationships. Optical properties were investigated with a combination of steady-state and time-resolved spectroscopic techniques. Steady-state spectroscopic data for the 3-arm dendrimers suggests that the exciton is delocalized over the alpha-conjugated thiophene segment and the phenyl core, but that the meta-linking of the dendrons prevents their electronic communication. In contrast, conjugation through the core to dendrons in the ortho and para positions is permitted in the 4-arm dendrimers, although the data suggest that the conjugation length does not extend over the full length of the alpha-conjugated sections of two coupled dendrons. This observation is due to steric interactions between neighboring arms, which forces the arms to twist and bend out of the plane of the phenyl core, and is particularly prevalent in disrupting the conjugation through the ortho positions. As expected, our results show that an increase in the bridge length results in an increase in the conjugation length for both dendrimers, and a subsequent red-shift of the absorption and emission. In addition, an increase in the dendron length results in an increase in the photoluminescence quantum yield and lifetime, suggesting that the ground and excited-state geometries are very similar and that the electronic transition is coupled to fewer vibrational modes.

AB The temperature-dependent local structures of cuprites (M2O for M = Cu-I, Ag-I) have been probed using variable-temperature (80-500 K) high-resolution pair distribution function (PDF) analysis of X-ray scattering data measured to very high values of momentum transfer (Q(max) = 35 angstrom(-1)). These noble metal oxides exhibit negative thermal expansion (NTE) behavior; however, several unusual structural features and behaviors distinguish the cuprites from other NTE frameworks-the structure is inverted relative to conventional NTE frameworks and Cu2O (but not Ag2O) shows an unusual transition from negative to positive thermal expansion behavior at higher temperature-thus motivating the present in-depth analysis of the particular thermal expansion mechanisms operating here. By coupling the local structural information from the PDFs with known geometric identities of the tetrahedra that form the framework, distortions contributing to NTE have been identified and the contrasting high temperature behaviors of the two isostructural analogues have been accounted for. Specifically, we demonstrate that thermal population of low-energy vibrational modes involving the dynamic distortion of the OM4 tetrahedra, away from the regular tetrahedral geometry (through M-O-M' bending), can induce a contraction of the average tetrahedral edge length (M center dot center dot center dot M') and thus contribute to the NTE effect. This mechanism operates in combination with the transverse vibrational mechanism found in conventional NTE frameworks, where increasing transverse displacement of the bridging atom (O-M-O') draws corner-bridged polyhedra closer together.

AB During the intense magnetic storm of 15 December 2006, the midlatitude Super Dual Auroral Radar Network (SuperDARN) Hokkaido radar observed a dynamical character of rapid, westward flows at 50-56 magnetic latitude. The simulation that couples the inner magnetosphere and the subauroral ionosphere was performed using a realistic boundary condition of the hot ion distribution determined from four Los Alamos National Laboratory satellites at 6.6 R-E. The following results are obtained using the simulation: ( 1) In general, morphology of the azimuthal component of the simulated ionospheric plasma flow is consistent with that known as the subauroral polarization stream ( SAPS), ( 2) an increase in the hot ion density in the plasma sheet results in the temporal reduction and subsequent intensification of the rapid flow at certain subauroral latitudes with a delay of similar to 40 min, and ( 3) influence of the plasma sheet temperature on the rapid flow is not evident. The simulated line-of-sight velocity is compared with that obtained by the SuperDARN Hokkaido radar. Agreement between them is found in terms of the temporal and spatial variations of the rapid flows as well as the flow velocity. It is suggested that the dynamical character of the subauroral plasma flow is a direct manifestation of the plasma pressure distribution in the inner magnetosphere ( the ring current) especially during the magnetic storm.

AB Many bacteria can rapidly traverse surfaces from which they are extracting nutrient for growth. They generate flat, spreading colonies, called swarms because they resemble swarms of insects. We seek to understand how members of any dense swarm spread efficiently while being able to perceive and interfere minimally with the motion of others. To this end, we investigate swarms of the myxobacterium, Myxococcus xanthus. Individual M. xanthus cells are elongated; they always move in the direction of their long axis; and they are in constant motion, repeatedly touching each other. Remarkably, they regularly reverse their gliding directions. We have constructed a detailed cell- and behavior-based computational model of M. xanthus swarming that allows the organization of cells to be computed. By using the model, we are able to show that reversals of gliding direction are essential for swarming and that reversals increase the outflow of cells across the edge of the swarm. Cells at the swarm edge gain maximum exposure to nutrient and oxygen. We also find that the reversal period predicted to maximize the outflow of cells is the same (within the errors of measurement) as the period observed in experiments with normal M. xanthus cells. This coincidence suggests that the circuit regulating reversals evolved to its current sensitivity under selection for growth achieved by swarming. Finally, we observe that, with time, reversals increase the cell alignment, and generate clusters of parallel cells.

AB Although impaired inhibitory control is linked to a broad spectrum of health problems, including obesity, the brain mechanism(s) underlying voluntary control of hunger are not well understood. We assessed the brain circuits involved in voluntary inhibition of hunger during food stimulation in 23 fasted men and women using PET and 2-deoxy-2[ (18)F] fluoro-D-glucose ((18)FDG). In men, but not in women, food stimulation with inhibition significantly decreased activation in amygdala, hippocampus, insula, orbitofrontal cortex, and striatum, which are regions involved in emotional regulation, conditioning, and motivation. The suppressed activation of the orbitofrontal cortex with inhibition in men was associated with decreases in self-reports of hunger, which corroborates the involvement of this region in processing the conscious awareness of the drive to eat. This finding suggests a mechanism by which cognitive inhibition decreases the desire for food and implicates lower ability to suppress hunger in women as a contributing factor to gender differences in obesity.

For the porous low-k/Cu(Mn) system, we provide evidence that the interface is composed of MnSiO3 and MnO with near complete Mn segregation from the alloy film; however, we find that the self-forming process does not go to full completion on thermally grown SiO2 substrates.

AB Polarization switching in polycrystalline PbZr(0.52)Ti(0.48)O(3) films on Pt-coated Si substrates was studied by switching spectroscopy piezoresponse force microscopy (SSPFM). Acquisition of multiple hysteresis loops allows polarization switching parameters, including nucleation, coercive biases, and switchable response to be mapped in real space. In contrast to measurements made on the free surface, those on the metal-ferroelectric-metal capacitor structures show the evolution of correlated switching of 10(2)-10(3) grain clusters with well-defined imprint and nucleation biases. The role of substrate bending on clustering and SSPFM detection mechanisms are discussed. These studies demonstrate real-space imaging of mesoscopic polarization reversal in real-world devices.

AB The structural and electronic properties of Cu2ZnSnS4 and Cu2ZnSnSe4 are studied using first-principles calculations. We find that the low energy crystal structure obeys the octet rule and is the kesterite (KS) structure. However, the stannite or partially disordered KS structures can also exist in synthesized samples due to the small energy cost. We find that the dependence of the band structure on the (Cu,Zn) cation ordering is weak and predict that the band gap of Cu2ZnSnSe4 should be on the order of 1.0 eV and not 1.5 eV as was reported in previous absorption measurements.

AB We show in this work that GaAs capping of 2 ML of GaSb grown by molecular beam epitaxy results in the formation of very small (with heights of about 1 nm) GaAs(x)Sb(1-x) nanostructures surrounded by a GaAs rich layer. This conclusion is obtained by analyzing the morphology of the GaAs(x)Sb(1-x) nanostructures by high resolution scanning transmission electron microscopy in Z-contrast mode. This result shows that a significant fraction of the Sb atoms must segregate along the growth direction during the GaAs capping process.

DE Modeling; Uncertainty; Heterogeneity
AB Qualitative evaluation of the effects of uncertainties originating from scenario development, modeling approaches, and parameter values is an important subject in the area of safety assessment for high-level nuclear waste disposal sites. in this study, regional-scale groundwater How analyses for the Tono area, Japan were conducted using three continuous models designed to handle heterogeneous porous media. We evaluated the simulation results to quantitatively analyze uncertainties originating from modeling approaches. We found that porous media heterogeneity is the main factor which causes uncertainties. We also found that uncertainties originating from modeling approaches greatly depend on the types of hydrological structures and heterogeneity of hydraulic conductivity values in the domain assigned by modelers. Uncertainties originating from modeling approaches decrease as the amount of labor and time spent increase, and iterations between investigation and analyses increases. (C) 2008 Elsevier B.V.

TI Search for a scalar or vector particle decaying into Z gamma in

ID HADRON COLLIDERS; BOSON; COUPLINGS
AB We present a search for a narrow scalar or vector resonance decaying into Z gamma with a subsequent Z boson decay into a pair of electrons or moons. The data for this search were collected with the D circle divide detecror at the Fermilab Tevatron p (p) over bar collider at a center of mass energy root s = 1.96 TeV. Using 1.1 (1.0) fb(-1) of data, we observe 49 (50) candidate events in the electron (muon) channel, in good agreement with the standard model prediction. From the combination of both channels, we derive 95% C.L. upper limits on the cross section times branching fraction (sigma x B) into Z gamma. These limits range from 0.19 (0.20) pb for a scalar (vector) resonance mass of 600 GeV/c(2) to 2.5 (3.1) pb for a mass of 140 GeV/c(2). Published by Elsevier B.V.

AB We discuss a class of gauge mediated supersymmetry breaking models with conformal invariance above the messenger mass scale (conformal gauge mediation). The spectrum of the supersymmetric particles including the gravitino is uniquely determined by the messenger mass. When the conformal fixed point is strongly interacting, it predicts a light gravitino of mass m(3/2) < O(10) eV, which is attractive since such a light gravitino causes no problem in cosmology.

AB Density-functional theory (DFT) calculations were performed to determine the structure and stability of oxygen, carbon monoxide and sulfur adsorption on Cu(111), (100) and (110) surfaces that are in equilibrium with a water-gas shift (WGS) reactive environment of H(2), H(2)S. H(2)O and CO. An atomistic thermodynamic framework based on DFT was used for describing the phase behaviors of the adsorbates on different Cu facets. Phase diagrams of each possible adsorbate on each surface were constructed as a function of the corresponding chemical potential which showed sulfur poisoning occurs even at ppm levels of H2S in the environment at low temperatures. Under reaction conditions relevant to WGS at low temperature, CO and S adsorbed surface structures were found to be more stable then the clean catalyst surfaces. At high temperatures and high hydrogen pressures, a poisoned surface can be regenerated back to a clean surface. The shapes of a Cu nanoparticle in the WGS reaction conditions under various sulfur chemical potentials were determined using the Wulff construction. We found that the crystal shape changes significantly from one dominated by (111) and (100) facets at very low sulfur chemical potentials to a shape dominated by (110) facets at higher sulfur chemical potentials, suggesting that reactive site distributions may change under reaction conditions.

AB We report an investigation or inverse energy cascade in steady-state two-dimensional turbulence by direct numerical simulation (DNS) of the two-dimensional Navier-Stokes equation, with small-scale forcing and large-scale damping. We employed several types of damping and dissipation mechanisms in simulations up to 2048(2) resolution. For all these simulations we obtained a wavenumber range for which the mean spectral energy flux is a negative constant and the energy spectrum scales as k (5/3), consistent with the predictions of Kraichnan (Phys. Fluids, vol. 439, 1967, p. 1417). To gain further insight, we investigated the energy cascade in physical space, employing a local energy flux defined by smooth filtering. We found that the inverse energy cascade is scale local, but that the strongly local contribution vanishes identically, as argued by Kraichnan (J. Fluid Mech., vol. 47, 1971, p. 525). The mean flux across a length scale l was shown to be due mainly to interactions with modes two to eight times smaller. A major part of our investigation was devoted to identifying the physical mechanism of the two-dimensional inverse energy cascade. One popular idea is that inverse energy cascade proceeds via merger of like-sign vortices. We made a quantitative study employing a precise topological criterion of merger events. Our statistical analysis showed that vortex mergers play a negligible direct role in producing mean inverse energy flux in our simulations. Instead, we obtained with the help of other works considerable evidence in favour of a 'vortex thinning' mechanism, according to which the large-scale strains do negative work against turbulent stress as they stretch out the isolines of small-scale vorticity. In particular, we studied a multi-scale gradient (MSG) expansion developed by Eyink (J. Fluid Mech., vol. 549, 2006a, p. 159) for the turbulent stress, whose contributions to inverse cascade call all be explained by 'thinning'. The MSG expansion up to second order ill space gradients was found to predict well the magnitude, spatial structure and scale distribution of the local energy flux. The majority of mean flux was found to be due to the relative rotation of strain matrices at different length scales, a first-order effect of 'thinning'. The remainder arose from two second-order effects, differential strain rotation and vorticity gradient stretching. Our findings give strong support to vortex thinning as the fundamental mechanism of two-dimensional inverse energy cascade.

AB The multifilter rotating shadowband radiometer (MFRSR) measures direct and diffuse irradiances in the visible and near-infrared spectral range. In addition to characteristics of atmospheric aerosols, MFRSR data also allow retrieval of precipitable water vapor (PWV) column amounts, which are determined from the direct normal irradiances in the 940-nm spectral channel. The HITRAN 2004 spectral database was used in our retrievals to model the water vapor absorption. We present a detailed error analysis describing the influence of uncertainties in instrument calibration and spectral response, as well as those in available spectral databases, on the retrieval results. The results of our PWV retrievals from the Southern Great Plains (SGP) site operated by the Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Program were compared with correlative standard measurements by microwave radiometers (MWRs) and a global positioning system (GPS) water vapor sensor, as well as with retrievals from other solar radiometers (AERONET's CIMEL, AATS-6). Some of these data are routinely available at the SGP's Central Facility; however, we also used measurements from a wider array of instrumentations deployed at this site during the water vapor intensive observation period (WVIOP2000) in September-October 2000. The WVIOP data show better agreement between different solar radiometers or between different microwave radiometers (both groups showing relative biases within 4%) than between these two groups of instruments, with MWR values being consistently higher (up to 14%) than those from solar instruments (especially in the large PWV column amount range). We also demonstrate the feasibility of using MFRSR network data for creation of 2D data sets comparable with that of the MODIS satellite water vapor product.

AB This article provides an overview of recent developments regarding synthesis of Pd nanocrystals with well-controlled shapes in aqueous solutions. In a solution-phase synthesis, the final shape taken by a nanocrystal is determined by the twin structures of seeds and the growth rates of different crystallographic facets. Here, the maneuvering of these factors in an aqueous system to achieve shape control for Pd nanocrystals is discussed. L-ascorbic acid, citric acid, and poly(vinyl pyrrolidone) are tested for manipulating the reduction kinetics, with citric acid and Br(-) ions used as capping agents to selectively promote the formation of {111} and {100} facets, respectively. The distribution of single-crystal versus multiple-twinned seeds can be further manipulated by employing or blocking oxidative etching. The shapes obtained for the Pd nanocrystals Include truncated octahedron, icosahedron, octahedron, decahedron, hexagonal and triangular plates, rectangular bar, and cube. The ability to control the shape of Pd nanocrystals provides a great opportunity to systematically Investigate their catalytic, electrical, and plasmonic properties.

AB The nuclear pore complex (NPC) regulates the bidirectional movement of cell components across the nuclear envelope. In this issue, D'Angelo et al. (2009) demonstrate that the NPC loses essential protein subunits as cells age, resulting in increased nuclear permeability and potentially contributing to organismal aging.

ID PROPER ORTHOGONAL DECOMPOSITION; PHYSICAL INTERPRETATION; SYSTEMS;
MODES; REDUCTION
AB The proper orthogonal decomposition is a method that may be applied to linear and nonlinear structures for extracting important information from a measured structural response. This method is often applied for model reduction of linear and nonlinear systems and has been applied recently for time-varying system identification. Although methods have previously been developed to identify time-varying models for simple linear and nonlinear structures using the proper orthogonal decomposition of a measured structural response, the application of these methods has been limited to cases where the excitation is either an initial condition or an applied load but not a combination of the two. This paper presents a method for combining previously published proper orthogonal decomposition-based identification techniques for strictly free or strictly forced systems to identify predictive models for a system when only mixed response data are available, i.e. response data resulting from initial conditions and loads that are applied together. This method extends the applicability of the previous proper orthogonal decomposition-based identification techniques to operational data acquired outside of a controlled laboratory setting. The method is applied to response data generated by finite element models of simple linear time-invariant, time-varying, and nonlinear beams and the strengths and weaknesses of the method are discussed.

TI Search for High-Mass e(+) e(-) Resonances in p (p)over-bar Collisions at
root s=1.96 TeV

AB A search for high-mass resonances in the e(+)e(-) final state is presented based on 2: 5 fb(-1) of root s = 1.96 TeV p (p) over bar collision data from the CDF II detector at the Fermilab Tevatron. The largest excess over the standard model prediction is at an e(+)e(-) invariant mass of 240 GeV/c(2). The probability of observing such an excess arising from fluctuations in the standard model anywhere in the mass range of 150-1000 GeV/c(2) is 0.6% ( equivalent to 2.5 sigma). We exclude the standard model coupling Z' and the Randall-Sundrum graviton for k/(M) over bar (P1) = 0.1 with masses below 963 and 848 GeV/c(2) at the 95% credibility level, respectively.

TI Measurement of the Angular and Lifetime Parameters of the Decays B-d(0)
-> J/psi K*(0) and B-s(0) -> J/psi phi
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
AB We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays B-d(0) --> J/psi K*(0) and B-s(0) --> J/psi phi in the transversity basis. We also measure the mean lifetime (tau) over bar (s) of the B-s(0) mass eigenstates and the lifetime ratio (tau) over bar (s)/tau(d). The analyses are based on approximately 2.8 fb(-1) of data recorded with the D0 detector. From our measurements of the angular parameters we conclude that there is no evidence for a deviation from flavor SU( 3) symmetry for these decays and that the factorization assumption is not valid for the B-d(0) --> J/psi K*(0) decay.

TI Magnetic Structure of RuSr2GdCu2O8 Determined by Resonant X-Ray
Diffraction
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID SUPERCONDUCTIVITY; COEXISTENCE; EXCHANGE
AB X-ray diffraction with photon energies near the Ru L-2-absorption edge was used to detect resonant reflections characteristic of a G-type superstructure in RuSr2GdCu2O8 single crystals. A polarization analysis confirms that these reflections are due to magnetic order of Ru moments, and the azimuthal-angle dependence of the scattering amplitude reveals that the moments lie along a low-symmetry axis with substantial components parallel and perpendicular to the RuO2 layers. Complemented by susceptibility data and a symmetry analysis of the magnetic structure, these results reconcile many of the apparently contradictory findings reported in the literature.

TI Search for Chameleon Particles Using a Photon-Regeneration Technique
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID INVISIBLE-AXION; ENERGY
AB We report the first results from the GammeV search for chameleon particles, which may be created via photon-photon interactions within a strong magnetic field. Chameleons are hypothesized scalar fields that could explain the dark energy problem. We implement a novel technique to create and trap the reflective particles within a jar and to detect them later via their afterglow as they slowly convert back into photons. These measurements provide the first experimental constraints on the couplings of chameleons to photons.

TI Design of Narrow-Gap TiO2: A Passivated Codoping Approach for Enhanced
Photoelectrochemical Activity
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID INITIO MOLECULAR-DYNAMICS; AUGMENTED-WAVE METHOD; TITANIUM-DIOXIDE;
WATER; ANATASE; PHOTOCATALYSIS; OXIDATION; METALS
AB To improve the photoelectrochemical activity of TiO2 for hydrogen production through water splitting, the band edges of TiO2 should be tailored to match with visible light absorption and the hydrogen or oxygen production levels. By analyzing the band structure of TiO2 and the chemical potentials of the dopants, we propose that the band edges of TiO2 can be modified by passivated codopants such as (Mo+C) to shift the valence band edge up significantly, while leaving the conduction band edge almost unchanged, thus satisfying the stringent requirements. The design principle for the band-edge modification should be applicable to other wide-band-gap semiconductors.

ID ALCATOR C-MOD; TOROIDAL ROTATION; STABILIZATION; PARTICLE; WAVES; PINCH;

AB In Alcator C-Mod discharges lower hybrid waves have been shown to induce a countercurrent change in toroidal rotation of up to 60 km/s in the central region of the plasma (r/a similar to < 0.4). This modification of the toroidal rotation profile develops on a time scale comparable to the current redistribution time (similar to 100 ms) but longer than the energy and momentum confinement times (similar to 20 ms). A comparison of the co- and countercurrent injected waves indicates that current drive (as opposed to heating) is responsible for the rotation profile modifications. Furthermore, the changes in central rotation velocity induced by lower hybrid current drive (LHCD) are well correlated with changes in normalized internal inductance. The application of LHCD has been shown to generate sheared rotation profiles and a negative increment in the radial electric field profile consistent with a fast electron pinch.

TI Band Structure Asymmetry of Bilayer Graphene Revealed by Infrared
Spectroscopy
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID BERRYS PHASE
AB We report on infrared spectroscopy of bilayer graphene integrated in gated structures. We observe a significant asymmetry in the optical conductivity upon electrostatic doping of electrons and holes. We show that this finding arises from a marked asymmetry between the valence and conduction bands, which is mainly due to the inequivalence of the two sublattices within the graphene layer and the next-nearest-neighbor interlayer coupling. From the conductivity data, the energy difference of the two sublattices and the interlayer coupling energy are directly determined.

AB We measured the thermal conductivity kappa of an 80 mu m thick hydrogenated amorphous silicon film prepared by hot-wire chemical-vapor deposition with the 3 omega (80-300 K) and the time-domain thermoreflectance (300 K) methods. The kappa is higher than any of the previous temperature dependent measurements and shows a strong phonon mean free path dependence. We also applied a Kubo based theory using a tight-binding method on three 1000 atom continuous random network models. The theory gives higher kappa for more ordered models, but not high enough to explain our results, even after extrapolating to lower frequencies with a Boltzmann approach. Our results show that this material is more ordered than any amorphous silicon previously studied.

TI Chiral and Collinear Ordering in a Distorted Triangular Antiferromagnet
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID LATTICE
AB Magnetization, specific heat, and neutron diffraction measurements are used to map out the entire magnetic phase diagram of KFe(MoO(4))(2). This stacked triangular antiferromagnet is structurally similar to the famous multiferroic system RbFe(MoO(4))(2). Because of an additional small crystallographic distortion, it contains two sets of inequivalent distorted magnetic triangular lattices. As a result, the spin network breaks down into two intercalated yet almost independent magnetic subsystems. One is a collinear antiferromagnet that shows a simple spin-flop behavior in applied magnetic fields. The other is a helimagnet that instead goes through a series of exotic commensurate-incommensurate phase transformations. In the various phases one observes either true three-dimensional or unconventional quasi-two-dimensional ordering.

TI Gyrokinetic Studies on Turbulence-Driven and Neoclassical Nondiffusive
Toroidal-Momentum Transport and the Effect of Residual Fluctuations in
Strong ExB Shear
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID ION-TRANSPORT; PLASMAS
AB A significant inward flux of toroidal momentum is found in global gyrokinetic simulations of ion temperature gradient turbulence, leading to core plasma rotation spin-up. The underlying mechanism is identified to be the generation of residual stress due to the k(parallel to) symmetry breaking induced by global quasistationary zonal flow shear. Simulations also show a significant off-diagonal element associated with the ion temperature gradient in the neoclassical momentum flux, while the overall neoclassical flux is small. In addition, the residual turbulence found in the presence of strong ExB flow shear may account for neoclassical-level ion heat and anomalous momentum transport widely observed in experiments.

AB New geologic mapping, tectonic geomorphologic, (10)Be terrestrial cosmogenic nuclide, and (U-Th)/He zircon and apatite thermochronometric data provide the first numerical constraints on late Cretaceous to late Quaternary exhumation of the Inyo Mountains and vertical slip and horizontal extension rates across the eastern Inyo fault zone, California. The east-dipping eastern Inyo fault zone bounds the eastern flank of the Inyo Mountains, a prominent geomorphic feature within the western Basin and Range Province and eastern California shear zone. (U-Th)/He zircon and apatite thermochronometry yield age patterns across the range that are interpreted as indicating: (1) two episodes of moderate to rapid exhumation associated with Laramide deformation during the late Cretaceous/ early Tertiary; (2) development of a slowly eroding surface during a prolonged period from early Eocene to middle Miocene; (3) rapid cooling, exhumation, and initiation of normal slip along the eastern Inyo fault zone, accommodated by westward tilting of the Inyo Mountains block, at 15.6 Ma; and (4) rapid cooling, exhumation, and renewed normal slip along the eastern Inyo fault zone at 2.8 Ma. Fault slip continues today as indicated by fault scarps that cut late Pleistocene alluvial fan surfaces. The second episode of normal slip at 2.8 Ma also signals onset of dextral slip along the Hunter Mountain fault, yielding a Pliocene dextral slip rate of 3.3 +/- 1.0 mm/a, where a is years. Summing this dextral slip rate with estimated dextral slip rates along the Owens Valley, Death Valley, and Stateline faults yields a net geologic dextral slip rate across the eastern California shear zone of 9.3 + 2.2/-1.4 to 9.8 + 1.4/-1.0 mm/a.

AB The formation of electronic band structure by the valence-shell of Ar, Kr, and Xe clusters was studied for various cluster sizes using angle-resolved photoelectron spectroscopy. Different widths of the. ne-structure components in the cluster spectra are attributed to a splitting of the outermost p(3/2) levels due to valence-orbital overlap between neighboring atoms. Photoelectron angular distributions from the cluster differ from the atomic cases and vary substantially for different bands. The evolution of the electronic structure with increasing cluster size emulates the changes of the valence band structure in the transition from a condensed-phase monolayer to the bulk.

AB Complex thermochemistry modeling in the wake of a detonation or shock propagation requires accurate equations of state (EOS) for the resulting chemical species under high temperature and pressure. Nitrous acid (HONO or HNO(2)) has been shown to be an important post-detonation product for many energetic compounds. Given that its EOS has not been determined so far, either experimentally or theoretically, we develop a class II force field to model both conformers (i.e. cis and trans) of HONO, and compute the EOS using classical molecular dynamics simulations. We then show that this EOS can be well represented within a thermodynamics theory framework previously applied to other polar fluids. (C) 2008 Elsevier B. V. All rights reserved.

TI Analyzing the contribution of aerosols to an observed increase in direct
normal irradiance in Oregon
SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES
LA English
DT Article
ID SURFACE
AB Annual average total irradiance increases by 1-2% per decade at three monitoring stations in Oregon over the period from 1980 to 2007. Direct normal irradiance measurements increase by 5% per decade over the same time period. The measurements show no sign of a dimming before 1990. The impact of high concentrations of stratospheric aerosols following the volcanic eruptions of El Chichon and Mount Pinatubo are clearly seen in the measurements. Removing these years from the annual average all-sky time series reduces the trends in both total and direct normal irradiance. Clear-sky periods from this long direct normal time series are used in conjunction with radiative transfer calculations to test whether part of the increase could be caused by anthropogenic aerosols. All three sites show relatively low clear-sky measurements before the eruption of El Chichon in 1982, suggesting higher aerosol loads during this period. After removing the periods most strongly impacted by volcanic eruptions, two of the sites show statistically significant increases in clear-sky direct normal irradiance from 1987 to 2007. Radiative transfer calculations of the impact of volcanic aerosols and tropospheric water vapor indicate that only about 20% of that clear-sky increase between background aerosol periods before and after the eruption of Mount Pinatubo can be explained by these two factors. Thus a statistically significant clear-sky trend remains between 1987 and 2007 that is consistent with the hypothesis that at least some of the increase in surface irradiance could be caused by a reduction of anthropogenic aerosols.

AB Measurement of a stream offset and cosmogenic dating (Be-10) of the alluvial surface into which the stream incised yield a preferred late Holocene slip rate of 18.6 + 3.5/-3.3 mm a(-1) for the central part of the North Anatolian fault (NAF) at Tahtakopru, Turkey; use of variable cosmogenic production rate (VPR) models yields a slightly slower rate of similar to 16.4 + 6.4/-4.5 mm a(-1). The offset drainage (Karanlik Dere), which flows southward almost perpendicular to the east-west trace of the NAF at the site, is displaced right laterally by 55 +/- 10m, with no vertical displacement. A Be-10 age of similar to 3ka (similar to 3.5 ka VPR) from the top of a boulder on the best preserved part of the incised alluvial surface provides the most reliable maximum age for the onset of incision; 11 Be-10 ages from cobbles collected from the cultivated surface to the south yield younger ages, consistent with exhumation, erosion, and mechanical mixing during plowing. Our 18.6 + 3.5/-3.3 mm a(-1) rate is similar to other geologic slip rates measured along the NAF, all of which cluster between 15 and 20 mm a(-1) over a wide range of (10(3)-10(5)) timescales. All of these geological rates, however, are slower than the similar to 25 +/- 2 mm a(-1) short-term rate of elastic strain accumulation measured geodetically. This disparity suggests the possibility that the NAF is experiencing a strain transient in which the lower crust beneath the fault is deforming faster than its long-term rate.

AB The use of ab initio potentials in Monte Carlo simulations aimed at investigating the nucleation kinetics of water clusters is complicated by the computational expense of the potential energy determinations. Furthermore, the common desire to investigate the temperature dependence of kinetic properties leads to an urgent need to reduce the expense of performing simulations at many different temperatures. A method is detailed that allows a Markov chain (obtained via Monte Carlo) at one temperature to be scaled to other temperatures of interest without the need to perform additional large simulations. This Markov chain temperature-scaling (TeS) can be generally applied to simulations geared for numerous applications. This paper shows the quality of results which can be obtained by TeS and the possible quantities which may be extracted from scaled Markov chains. Results are obtained for a 1-D analytical potential for which the exact solutions are known. Also, this method is applied to water clusters consisting of between 2 and 5 monomers, using Dynamical Nucleation Theory to determine the evaporation rate constant for monomer loss. Although ab initio potentials are not utilized in this paper, the benefit of this method is made apparent by using the Dang-Chang polarizable classical potential for water to obtain statistical properties at various temperatures.

AB In this study, we present a thermally stable multilayered transparent conducting oxide (TCO) functionalized for dye-sensitized solar cells (DSSCs). Nb-doped TiO(2) (NTO) layers deposited on conventional Sn-doped In(2)O(3) (ITO) substrates using pulsed laser deposition (PLD) enhanced the optical-to-electrical conversion efficiency of the DSSCs by as much as 17% compared to that of bare ITO-based DSSCs. The electrical properties and J-V characteristics of the multilayered NTO/ITO films showed that the improved cell performance was due to the facilitated charge injection from TiO(2) to ITO that resulted from the formation of an ohmic contact with ITO, as well as the conserved high conductivity of ITO after the oxidizing annealing process. Moreover, the NTO/ITO-based DSSC exhibited higher efficiency than a F-doped SnO(2)(FTO)-based one, which demonstrates that optimization of multilayered NTO-based TCOs is a realistic approach for achieving highly efficient photoenergy conversion devices.

AB Nanoscale hexagonal BN additive for ammonia borane, AB, is shown to decrease the onset temperature for hydrogen release. Both the nano-BN and the AB:nano-BN samples are prepared by ball milling. The materials are characterized by X-ray powder diffraction, (11)B muclear magnetic resonance, thermogravimetric analysis, differential scanning calorimetry, and mass spectrometry, and the hydrogen release is measured by a volumetric gas burette system. Several effects of the mixtures of AB:nano-BN are shown to be beneficial in comparison with neat AB. These are the decrease of the dehydrogenation temperature, the decrease in NH(3) formation, as well as the decrease of the exothermicity of hydrogen release with increasing the nano-BN concentration.

AB Rotating disk electrode measurements of acid-treated "Pt3Co" nanoparticles showed specific oxygen reduction reaction (ORR) activity (similar to 0.7 mA/cm(pt)(2) at 0.9 V vs RHE in 0.1 M HClO4 at room temperature), twice that of Pt nanoparticles. Upon annealing at 1000 K in vacuum, the ORR activity at 0.9 V was increased to similar to 1.4 mA/cM(pt)(2) (four times that of Pt nanoparticles). High-resolution transmission electron microscopy and aberration-corrected high-angle annular dark-field in the scanning transmission electron microscope was used to reveal surface atomic structure and chemical composition variations of "Pt3Co" nanoparticles on the atomic scale. Such information was then correlated to averaged Pt-Pt distance obtained from synchrotron X-ray powder diffraction data, surface coverage of oxygenated species from cyclic voltammograms, and synchrotron X-ray absorption spectroscopy. It is proposed that ORR activity enhancement of acid-leached "Pt3Co" relative to Pt nanoparticles is attributed to the formation of a percolated structure with Pt-rich and Pt-poor regions within individual particles, while the increase in the specific ORR activity of annealed "Pt3Co" nanoparticles relative to Pt can be attributed to the presence of surface Pt segregation.

AB In eukaryotes, small non- coding RNAs regulate gene expression, helping to control cellular metabolism, growth and differentiation, to maintain genome integrity, and to combat viruses and mobile genetic elements. These pathways involve two specialized ribonucleases that control the production and function of small regulatory RNAs. The enzyme Dicer cleaves double- stranded RNA precursors, generating short interfering RNAs and microRNAs in the cytoplasm. These small RNAs are transferred to Argonaute proteins, which guide the sequence- specific silencing of messenger RNAs that contain complementary sequences by either enzymatically cleaving the mRNA or repressing its translation. The molecular structures of Dicer and the Argonaute proteins, free and bound to small RNAs, have offered exciting insights into the molecular mechanisms that are central to RNA silencing pathways.

TI High-Q surface-plasmon-polariton whispering-gallery microcavity
SO NATURE

AB Surface plasmon polaritons (SPPs) are electron density waves excited at the interfaces between metals and dielectric materials(1). Owing to their highly localized electromagnetic fields, they may be used for the transport and manipulation of photons on subwavelength scales(2-9). In particular, plasmonic resonant cavities represent an application that could exploit this field compression to create ultra-smal-lmode- volume devices. Akey figure of merit in this regard is the ratio of cavity quality factor, Q ( related to the dissipation rate of photons confined to the cavity), to cavity mode volume, V ( refs 10, 11). However, plasmonic cavity Q factors have so far been limited to values less than 100 both for visible and near- infrared wave-lengths(12) (-16). Significantly, such values are far below the theoretically achievable Q factors for plasmonic resonant structures. Here we demonstrate a high- Q SPP whispering- gallery microcavity that is made by coating the surface of a high- Q silica microresonator with a thin layer of a noble metal. Using this structure, Q factors of 1,376+/-65 can be achieved in the near infrared for surface- plasmonic whispering- gallery modes at room temperature. This nearly ideal value, which is close to the theoretical metal- loss- limited Q factor, is attributed to the suppression and minimization of radiation and scattering losses that are made possible by the geometrical structure and the fabrication method. The SPP eigenmodes, as well as the dielectric eigenmodes, are confined within the whispering- gallery microcavity and accessed evanescently using a single strand of low-loss, tapered optical waveguide(17,18). This coupling scheme provides a convenient way of selectively exciting and probing confined SPP eigenmodes. Up to 49.7 per cent of input power is coupled by phase- matching control between the microcavity SPP and the tapered fibre eigenmodes.

AB In the instantaneous normal mode method, normal mode analysis is performed at instantaneous configurations of a condensed-phase system, leading to modes with negative eigenvalues. These negative modes provide a means of characterizing local anharmonicities of the potential energy surface. Here, we apply instantaneous normal mode to analyze temperature-dependent diffusive dynamics in molecular dynamics simulations of a small protein (a scorpion toxin). Those characteristics of the negative modes are determined that correlate with the dynamical (or glass) transition behavior of the protein, as manifested as an increase in the gradient with T of the average atomic mean-square displacement at similar to 220 K. The number of negative eigenvalues shows no transition with temperature. Further, although filtering the negative modes to retain only those with eigenvectors corresponding to double-well potentials does reveal a transition in the hydration water, again, no transition in the protein is seen. However, additional filtering of the protein double-well modes, so as to retain only those that, on energy minimization, escape to different regions of configurational space, finally leads to clear protein dynamical transition behavior. Partial minimization of instantaneous configurations is also found to remove nondiffusive imaginary modes. In summary, examination of the form of negative instantaneous normal modes is shown to furnish a physical picture of local diffusive dynamics accompanying the protein glass transition.

TI Nonlocal Helix Formation Is Key to Understanding S-Adenosylmethionine-1
Riboswitch Function
SO BIOPHYSICAL JOURNAL
LA English
DT Article
ID S-ADENOSYLMETHIONINE; RNA STRUCTURE; MECHANISM; BINDING
AB Riboswitches are noncoding RNAs that regulate gene expression in response to changing concentrations of specific metabolites. Switching activity is affected by the interplay between the aptamer domain and expression platform of the riboswitch. The aptamer domain binds the metabolite, locking the riboswitch in a ligand-bound conformation. In absence of the metabolite, the expression platform forms an alternative secondary structure by sequestering the 3' end of a nonlocal helix called P1. We use all-atom structure-based simulations to characterize the folding, unfolding, and metabolite binding of the aptamer domain of the S-adenosylmethionine-1 (SAM-1) riboswitch. Our results suggest that folding of the nonlocal helix (P1) is rate-limiting in aptamer domain formation. Interestingly, SAM assists folding of the P1 helix by reducing the associated free energy barrier. Because the 3' end of the P1 helix is sequestered by an alternative helix in the absence of metabolites, this observed ligand-control of P1 formation provides a mechanistic explanation of expression platform regulation.

AB In this work, a constrained density functional theory based configuration interaction approach (CDFT-CI) is applied to calculating transition state energies of chemical reactions that involve bond forming and breaking at the same time. At a given point along the reaction path, the configuration space is spanned by two diabaticlike configurations: reactant and product. Each configuration is constructed self-consistently with spin and charge constraints to maximally retain the identities of the reactants or the products. Finally, the total energy is obtained by diagonalizing an effective Hamiltonian constructed in the basis spanned by these two configurations. By design, this prescription does not affect the energies of the reactant or product species but will affect the energy at intermediate points along the reaction coordinate, most notably by modifying the reaction barrier height. When tested with a large set of reactions that include hydrogen transfer, heavy atom transfer, and nucleophilic substitution, CDFT-CI is found to improve the prediction of barrier heights by a factor of 2-3 for some commonly used local, semilocal, and hybrid functionals. Thus, just as CDFT can be used to cure energy errors in charge localized states, CDFT-CI can recover the correct energy for charge delocalized states by approximating the true wave function as a linear combination of localized configurations (e.g., reactant and product). The well-defined procedure and the promising results of CDFT-CI suggest that it could broaden the applicability of traditional DFT methods for reaction barrier heights.

AB We discuss connections between the nonlinear dynamics of double-stranded DNA, experimental findings, and specific DNA functions. We begin by discussing how thermally induced localized openings ( bubbles) of the DNA double strand are important for interpreting dynamic force spectroscopy data. Then we demonstrate a correlation between a sequence-dependent propensity for pre-melting bubble formation and transcription initiation and other regulatory effects in viral DNA. Finally, we discuss the possibility of a connection between DNA dynamics and the ability of repair proteins to recognize ultraviolet ( UV) radiation damage sites.

AB Electron beam welding (EBW) of two important engineering alloys, Ti-6Al-4V and 21Cr-6Ni-9Mn, was studied experimentally and theoretically. The temperatures at several monitoring locations in the specimens were measured as a function of time during welding and the cross-sections of the welds were examined by optical microscopy. The theoretical research involved numerical simulation of heat transfer and fluid flow during EBW. The model output included temperature and velocity fields, fusion zone geometry and temperature versus time results. The numerically computed fusion zone geometry and the temperature versus time plots were compared with the corresponding experimentally determined values for each weld.
Both the experimental and the modelling results were compared with the corresponding results for the keyhole mode laser beam welding (LBW). Both experimental and modelling results demonstrate that the fusion zone size in Ti-6Al-4V alloy was larger than that of the 21Cr-6Ni-9Mn stainless steel during both the electron beam and laser welding. Higher boiling point and lower solid state thermal conductivity of Ti-6Al-4V contributed to higher peak temperatures in Ti-6Al-4V welds compared with 21Cr-6Ni-9Mn stainless steel welds. In the EBW of both the alloys, there were significant velocities of liquid metal along the keyhole wall driven by the Marangoni convection. In contrast, during LBW, the velocities along the keyhole wall were negligible. Convective heat transfer was important in the transport of heat in the weld pool during both the laser and the EBW. The computed keyhole wall temperatures during EBW at low pressures were lower than those during the LBW at atmospheric pressure for identical heat input.

AB The reactivity of vanadium complexes bearing the ligand dipicolinic acid (H(2)dipic) with alcohols has been explored. Dipic vanadium complexes are able to catalyze the aerobic oxidative C-C bond cleavage of pinacol. Reaction under anaerobic conditions allowed for isolation of a V(III) mu-oxo dimer, supporting the involvement of V(III) in aerobic oxidation reactions. Stoichiometric oxidation of unactivated aliphatic alcohols has also been observed, with oxidation of cyctobutanot producing cyclobutanone in 93% yield. The absence of ring-opening products in this reaction provides further support for the involvement of V(III) intermediates.

AB Single-walled carbon nanotube (SWCNT) fibers were engineered to become a scaffold for the storage of hydrogen. Carbon nanotube fibers were swollen in oleum (fuming sulfuric acid), and organic spacer groups were covalently linked between the nanotubes using diazonium functionalization chemistry to provide 3-dimensional (3-D) frameworks for the adsorption of hydrogen molecules. These 3-D nanoengineered fibers physisorb twice as much hydrogen per unit surface area as do typical macroporous carbon materials. These fiber-based systems can have high density, and combined with the outstanding thermal conductivity of carbon nanotubes, this points a way toward solving the volumetric and heat-transfer constraints that limit some other hydrogen-storage supports.

TI Impaired Acid Catalysis by Mutation of a Protein Loop Hinge Residue in a

AB Catalysis by the Yersinia protein-tyrosine phosphatase YopH is significantly impaired by the mutation of the conserved Trp354 residue to Phe. Though not a catalytic residue, this Trp is a hinge residue in a conserved flexible loop (the WPD-loop) that must close during catalysis. To learn why this seemingly conservative mutation reduces catalysis by 2 orders of magnitude, we have solved high-resolution crystal structures for the W354F YopH in the absence and in the presence of tungstate and vanadate. Oxyanion binding to the P-loop in W354F is analogous to that observed in the native enzyme. However, the WPD-loop in the presence of oxyanions assumes a half-closed conformation, in contrast to the fully closed state observed in structures of the native enzyme. This observation provides an explanation for the impaired general acid catalysis observed in kinetic experiments with Trp mutants. A 1.4 angstrom structure of the W354F mutant obtained in the presence of vanadate reveals an unusual divanadate species with a cyclic [VO](2) core, which has precedent in small molecules but has not been previously reported in a protein crystal structure.

AB Galaxy Zoo is the first study of nearby galaxies that contains reliable information about the spiral sense of rotation of galaxy arms for a sizeable number of galaxies. We measure the correlation function of spin chirality (the sense in which galaxies appear to be spinning) of face-on spiral galaxies in angular, real and projected spaces. Our results indicate a hint of positive correlation at separations less than similar to 0.5 Mpc at a statistical significance of 2 sigma-3 sigma. This is the first experimental evidence for chiral correlation of spins. Within the tidal torque theory, it indicates that the inertia tensors of nearby galaxies are correlated. This is complementary to the studies of nearby spin axis correlations that probe the correlations of the tidal field. Theoretical interpretation is made difficult by the small distances at which the correlations are detected, implying that substructure might play a significant role, and our necessary selection of face-on spiral galaxies, rather than a general volume-limited sample.

AB We report on the measurement of the radiation hardness of silicon photomultipliers (SiPMs) manufactured by Fondazione Bruno Kessler in Italy (1 and 6.2 mm(2)), Center of Perspective Technology and Apparatus in Russia (1 and 4.4 mm(2)), and Hamamatsu Corporation in Japan (1 mm(2)). The SiPMs were irradiated using a beam of 212 MeV protons at Massachusetts General Hospital, receiving fluences of up to 3 x 10(10) protons per cm(2) with the SiPMs at operating voltage. Leakage currents were read continuously during the irradiation. The delivery of the protons was paused periodically to record scope traces in response to calibrated light pulses to monitor the gains, photon detection efficiencies. and dark counts of the SiPMs. The leakage current and dark noise are found to increase with fluence. The leakage current is found to be proportional to the mean square deviation of the noise distribution, indicating the dark counts are due to increased random individual pixel activation, while SiPMs remain fully functional as photon detectors. The SiPMs are found to anneal at room temperature with a reduction in the leakage current by a factor of 2 in about 100 days. (c) 2008 Elsevier B.V. All rights reserved.

AB This manuscript profiles an unattended and fully autonomous radiation detection system sensitive to gamma-ray and neutron emissions. The Lynx design is intended for locations that require radiation detection capabilities for detection of special nuclear materials but lack supporting infrastructure. Signal-starved data is common in these environments since little or no control may be exerted over measurement conditions. The fundamental sensing elements of the Lynx system are traditional NaI(TI) and (3)He detectors. The new developments reported here center on two themes: low-power electronics and computationally simple analysis algorithms capable of discriminating gamma-ray signatures indicative of special nuclear materials from those of naturally occurring radioactive material. Incorporating tripwire-detection algorithms based on gamma-ray spectral signatures into a low-power electronics package significantly improves performance in environments where sensors encounter nuisance sources.

AB We propose a novel mechanism for the production of the Higgs boson in inclusive hadronic collisions, which utilizes the presence of heavy quarks in the proton wave function. In these inclusive reactions the Higgs boson acquires the momenta of both the heavy quark and antiquark and thus carries 80% or more of the projectile's momentum. We predict that the cross section d sigma/dx(F)(p (p) over bar --> HX) for the inclusive production of the Standard Model Higgs coming from intrinsic bottom Fock states is of order 150 fb at LHC energies, peaking in the region Of x(F) similar to 0.9. Our estimates indicate that the corresponding cross section coming from gluon-gluon fusion at x(F) = 0.9 is relatively negligible and therefore the peak from intrinsic bottom should be clearly visible for experiments with forward detection capabilities. The predicted cross section for the production of the Standard Model Higgs coming from intrinsic heavy quark Fock states in the proton is sufficiently large that detection at the Tevatron and the LHC may be possible.

AB A dramatic rise in the incidence of obesity in the U. S. has accelerated the search for interventions that may impact this epidemic. One recently recognized target for such intervention is adipose tissue, which secretes a variety of bioactive substances including prostaglandins. Prostaglandin E-2 (PGE(2)) has been shown to decrease lipolysis in adipocytes, but limited studies have explored alternative mechanisms by which PGE(2) might impact obesity, such as adipogenesis or lipogenesis. Studies conducted on Apc(Min/+) mice indicated that selective inhibition of the cyclooxygenase (COX)-2 enzyme led to significant reductions in fatty acid synthase (FAS) activity in adipose tissue suggesting lipogenic effects of PGE(2). To further investigate whether these lipid mediators directly regulate lipogenesis, we used 3T3-L1 adipocytes to determine the impact of eicosapentaenoic acid (EPA) and celecoxib on PGE(2) formation and FAS used as a lipogenic marker. Both arachidonic acid (AA) and EPA dose-dependently increased PGE secretion from adipocytes. AA was expectedly more potent and exhibiting at 150 uM dose a 5-fold increase in PGE(2) secretion over EPA. Despite higher secretion of PGE by EPA and AA compared to control, neither PUFA significantly altered FAS activity. By contrast both AA and EPA significantly decreased FAS mRNA levels. Addition of celecoxib, a selective COX-2 inhibitor, significantly decreased PGE(2) secretion (p < 0.05) versus control, and also significantly decreased FAS activity (p < 0.05). Unexpectedly, the combination of exogenous PGE(2) and celecoxib further decreased the FAS activity compared to PGE(2) alone or untreated controls. In conclusion, EPA-mediated inhibition of AA metabolism did not significantly alter FAS activity while both AA and EPA significantly decreased FAS mRNA expression. COX-2 inhibition significantly decreased PGE(2) production resulting in a decrease in FAS activity and expression that was not reversed with the addition of exogenous PGE(2), suggesting an additional mechanism that is independent of COX-2.

AB In recent work we presented the first results of global general relativistic magnetohydrodynamic (GRMHD) simulations of tilted (or misaligned) accretion disks around rotating black holes. The simulated tilted disks showed dramatic differences from comparable untilted disks, such as asymmetrical accretion onto the hole through opposing "plunging streams" and global precession of the disk powered by a torque provided by the black hole. However, those simulations used a traditional spherical-polar grid that was purposefully under-resolved along the pole, which prevented us from assessing the behavior of any jets that may have been associated with the tilted disks. To address this shortcoming we have added a block-structured "cubed-sphere" grid option to the Cosmos++ GRMHD code, which will allow us to simultaneously resolve the disk and polar regions. Here we present our implementation of this grid and the results of a small suite of validation tests intended to demonstrate that the new grid performs as expected. The most important test in this work is a comparison of identical tilted disks, one evolved using our spherical-polar grid and the other with the cubed-sphere grid. We also demonstrate an interesting dependence of the early-time evolution of our disks on their orientation with respect to the grid alignment. This dependence arises from the differing treatment of current sheets within the disks, especially whether or not they are aligned with symmetry planes of the grid.

AB On 2008 March 19, the northern sky was the stage of a spectacular optical transient that for a few seconds remained visible to the naked eye. The transient was associated with GRB 080319B, a gamma-ray burst (GRB) at a luminosity distance of about 6 Gpc (standard cosmology), making it the most luminous optical object ever recorded by humankind. We present comprehensive sky monitoring and multicolor optical follow-up observations of GRB 080319B collected by the RAPTOR telescope network covering the development of the explosion and the afterglow before, during, and after the burst. The extremely bright prompt optical emission revealed features that are normally not detectable. The optical and gamma-ray variability during the explosion are correlated, but the optical flux is much greater than can be reconciled with single-emission mechanism and a flat gamma-ray spectrum. This extreme optical behavior is best understood as synchrotron self-Compton model (SSC). After a gradual onset of the gamma-ray emission, there is an abrupt rise of the prompt optical flux, suggesting that variable self-absorption dominates the early optical light curve. Our simultaneous multicolor optical light curves following the flash show spectral evolution consistent with a rapidly decaying red component due to large-angle emission and the emergence of a blue forward-shock component from interaction with the surrounding environment. While providing little support for the reverse shock that dominates the early afterglow, these observations strengthen the case for the universal role of the SSC mechanism in generating GRBs.

AB We propose to use a simple observable, the fractional area of "hot spots" in weak gravitational lensing mass maps, which are detected with high significance, to determine background cosmological parameters. Because these high-convergence regions are directly related to the physical nonlinear structures of the universe, they derive cosmological information mainly from the nonlinear regime of density fluctuations. We show that in combination with future cosmic microwave background anisotropy measurements, this method can place constraints on cosmological parameters that are comparable to those from the redshift distribution of galaxy cluster abundances. The main advantage of the statistic proposed in this paper is that projection effects, normally the main source of uncertainty when determining the presence and the mass of a galaxy cluster, here serve as a source of information.

TI THE EFFECT OF PROGENITOR AGE AND METALLICITY ON LUMINOSITY AND Ni-56

AB Timmes et al. found that metallicity variations could theoretically account for a 25% variation in the mass of Ni-56 synthesized in Type Ia supernovae (SNe Ia), and thus account for a large fraction of the scatter in observed SN Ia luminosities. Higher-metallicity progenitors are more neutron rich, producing more stable burning products relative to radioactive Ni-56. We develop a new method for estimating bolometric luminosity and Ni-56 yield in SNe Ia and use it to test the theory with data from the Supernova Legacy Survey. We find that the average Ni-56 yield does drop in SNe Ia from high-metallicity environments, but the theory can only account for 7%-10% of the dispersion in SN Ia Ni-56 mass, and thus luminosity. This is because the effect is dominant at metallicities significantly above solar, whereas we find that SN hosts have predominantly subsolar or only moderately above-solar metallicities. We also show that allowing for changes in O/Fe with the metallicity [Fe/H] does not have a major effect on the theoretical prediction of Timmes et al., so long as one is using the O/H as the independent variable. Age may have a greater effect than metallicity-we find that the luminosity-weighted age of the host galaxy is correlated with Ni-56 yield, and thus more massive progenitors give rise to more luminous explosions. This is hard to understand if most SNe Ia explode when the primaries reach the Chandrasekhar mass. Finally, we test the findings of Gallagher et al. that the residuals of SNe Ia from the Hubble diagram are correlated with host galaxy metallicity, and we find no such correlation.

AB We use Hubble Space Telescope/Advanced Camera for Surveys images and a photometric catalog of the Cosmic Evolution Survey (COSMOS) field to analyze morphologies of the host galaxies of similar to 400 active galactic nucleus (AGN) candidates at redshifts 0.3 < z < 1.0. We compare the AGN hosts with a sample of nonactive galaxies drawn from the COSMOS field to match the magnitude and redshift distribution of the AGN hosts. We perform two-dimensional surface brightness modeling with GALFIT to yield host galaxy and nuclear point source magnitudes. X-ray-selected AGN host galaxy morphologies span a substantial range that peaks between those of early-type, bulge-dominated and late-type, disk-dominated systems. We also measure the asymmetry and concentration of the host galaxies. Unaccounted for, the nuclear point source can significantly bias results of these measured structural parameters, so we subtract the best-fit point source component to obtain images of the underlying host galaxies. Our concentration measurements reinforce the findings of our two-dimensional morphology fits, placing X-ray AGN hosts between early- and late-type inactive galaxies. AGN host asymmetry distributions are consistent with those of control galaxies. Combined with a lack of excess companion galaxies around AGN, the asymmetry distributions indicate that strong interactions are no more prevalent among AGN than normal galaxies. In light of recent work, these results suggest that the host galaxies of AGN at these X-ray luminosities may be in a transition from disk-dominated to bulge-dominated, but that this transition is not typically triggered by major mergers.

AB We present optical, X-ray, high-energy ((sic) 30 GeV) and very high energy ((sic) 100 GeV; VHE) observations of the high-frequency peaked blazar Mrk 421 taken between 2008 May 24 and June 23. A high-energy gamma-ray signal was detected by AGILE with root TS = 4.5 between June 9 and 15, with F(E > 100 MeV) = 42(-12)(+14) x 10(-8) photons cm(-2) s(-1). This flaring state is brighter than the average flux observed by EGRET by a factor of similar to 3, but still consistent with the highest EGRET flux. In hard X-rays (20-60 keV) SuperAGILE resolved a five-day flare (June 9-15) peaking at similar to 55 mCrab. SuperAGILE, RXTE/ASM and Swift/BAT data show a correlated flaring structure between soft and hard X-rays. Hints of the same flaring behavior are also detected in the simultaneous optical data provided by the GASP-WEBT. A Swift/XRT observation near the flaring maximum revealed the highest 2-10 keV flux ever observed from this source, of 2.6 x 10(-9) erg cm(-2) s(-1) (i.e. > 100 mCrab). A peak synchrotron energy of similar to 3 keV was derived, higher than typical values of similar to 0.5-1 keV. VHE observations with MAGIC and VERITAS between June 6 and 8 showed the flux peaking in a bright state, well correlated with the X-rays. This extraordinary set of simultaneous data, covering a 12-decade spectral range, allowed for a deep analysis of the spectral energy distribution as well as of correlated light curves. The gamma-ray flare can be interpreted within the framework of the synchrotron self-Compton model in terms of a rapid acceleration of leptons in the jet.

TI Transcriptomic and metabolomic profiling of Zymomonas mobilis during

AB Background: Zymomonas mobilis ZM4 (ZM4) produces near theoretical yields of ethanol with high specific productivity and recombinant strains are able to ferment both C-5 and C-6 sugars. Z. mobilis performs best under anaerobic conditions, but is an aerotolerant organism. However, the genetic and physiological basis of ZM4's response to various stresses is understood poorly.
Results: In this study, transcriptomic and metabolomic profiles for ZM4 aerobic and anaerobic fermentations were elucidated by microarray analysis and by high-performance liquid chromatography (HPLC), gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analyses. In the absence of oxygen, ZM4 consumed glucose more rapidly, had a higher growth rate, and ethanol was the major end-product. Greater amounts of other end-products such as acetate, lactate, and acetoin were detected under aerobic conditions and at 26 h there was only 1.7% of the amount of ethanol present aerobically as there was anaerobically. In the early exponential growth phase, significant differences in gene expression were not observed between aerobic and anaerobic conditions via microarray analysis. HPLC and GC analyses revealed minor differences in extracellular metabolite profiles at the corresponding early exponential phase time point.
Differences in extracellular metabolite profiles between conditions became greater as the fermentations progressed. GC-MS analysis of stationary phase intracellular metabolites indicated that ZM4 contained lower levels of amino acids such as alanine, valine and lysine, and other metabolites like lactate, ribitol, and 4-hydroxybutanoate under anaerobic conditions relative to aerobic conditions. Stationary phase microarray analysis revealed that 166 genes were significantly differentially expressed by more than two-fold. Transcripts for Entner-Doudoroff (ED) pathway genes (glk, zwf, pgl, pgk, and eno) and gene pdc, encoding a key enzyme leading to ethanol production, were at least 30-fold more abundant under anaerobic conditions in the stationary phase based on quantitative-PCR results. We also identified differentially expressed ZM4 genes predicted by The Institute for Genomic Research (TIGR) that were not predicted in the primary annotation.
Conclusion: High oxygen concentrations present during Z. mobilis fermentations negatively influence fermentation performance. The maximum specific growth rates were not dramatically different between aerobic and anaerobic conditions, yet oxygen did affect the physiology of the cells leading to the buildup of metabolic byproducts that ultimately led to greater differences in transcriptomic profiles in stationary phase.

AB The concentration of sulfuric acid by pervaporation has been studied using Naflon-112 (R) and Nafion-117 (R) membranes, which have been characterized in terms of flux, permeability, and separation factor at 100 and 120 degrees C. Feed acid concentrations investigated ranged from 40 to over 80wt%. In general, water fluxes ranged from 100 to 8000g/m(2) h, depending on feed acid concentration and separation factors as high as 10(4) were observed. Membrane stability was probed using dynamic mechanical analysis that revealed an increase in the temperature at which the alpha transition is observed, which corresponds to the glass transition (T(g)) of the hydrophilic domain, upon use, suggesting embrittlement of the polymer structure. Further studies showed that the embrittlement was due to an interaction with the acid and was not induced by the operating temperature. (C) 2008 Elsevier B.V. All rights reserved.

AB We assembled single-stranded DNA (ssDNA) conjugated nanoparticles using the phage M 13 gene 5 protein (g5p) as the molecular glue to bind two antiparallel noncomplementary ssDNA strands. The entire process was controlled tightly by the concentration of the g5p protein and the presence of double-stranded DNA. The g5p-ssDNA aggregate was disintegrated by hybridization with complementary ssDNA (C-ssDNA) that triggers the dissociation of the complex. Polyhistidine-tagged g5p was bound to nickel nitrilotriacetic acid (Ni(2+)-NTA) conjugated nanoparticles and subsequently used to coassemble the ssDNA-conjugated nanoparticles into multiparticle-type aggregates. Our approach offers great promise for designing biologically functional, controllable protein/nanoparticle composites.

AB Infrared spectroscopic ellipsometry was used for determination of molecular orientation and for lateral homogeneity studies of organic monolayers on GaAs and Au, the organic layer being either octanedithiol or hexadecanethiol (HDT). The laterally resolved measurements were performed with the infrared mapping ellipsometer at the synchrotron storage ring BESSY II. The molecular orientation within the monolayers was determined by optical model simulations of the measured ellipsometric spectra. Different tilt angles were obtained for the monolayers of HDT and octanedithiol on GaAs: 19 degrees and > 30 degrees, respectively. The tilt angle of the methylene chains for HDT on Au substrate (22 degrees) is similar to the 190 tilt which was obtained for the HDT monolayers on GaAs, thus suggesting similar molecular ordering of the thiolates on both substrates.

AB X-ray reflectivity and fluorescence near total reflection experiments were performed to examine the affinities of divalent ions (Ca2+ and Ba2+) from aqueous solution to a charged phosphatidic acid (PA) surface. A phospholipid (1,2-dimyristoyl-sn-glycero-3-phosphate, DMPA), spread as a monolayer at the air/water interface, was used to form and control the charge density at the interface. We find that, for solutions of the pure salts (i.e., CaCl2 and BaCl2), the number of bound ions per DMPA at the interface is saturated at concentrations that exceed 10(-3) M. For 1:1 Ca2+/Ba2+ mixed solutions, we find that the bound Ca2+/Ba2+ ratio at the interface is 4:1. If the only property determining charge accumulation near PA were the ionic charges, the concentration of mixed Ca2+/Ba2+ at the interface would equal that of the bulk. Our results show a clear specific affinity of PA for Ca compared to Ba. We provide some discussion on this issue as well as some implications for biological systems. Although our results indicate an excess of counterion charge with respect to the surface charge, that is, charge inversion, the analysis of both reflectivity and fluorescence do not reveal an excess of co-ions (namely, Cl- or I-).

AB Photocatalytic lithography (PCL) is an inexpensive, fast, and robust method of oxidizing surface chemical moieties to produce patterned substrates. This technique has utility in basic biological research as well as various biochip applications. We report on porphyrin-based PCL for patterning poly(propylene sulfide) block copolymer films on gold substrates on the micrometer and submicrometer scales. We confirm chemical patterning with imaging ToF-SIMS and low-voltage SEM. Biomolecular patterning on micrometer and submicrometer scales is demonstrated with proteins, protein-linked beads. and fluorescently labeled proteins.

AB Hydrogen atoms constitute about half of all atoms in proteins and play a critical role in enzyme mechanisms and macromolecular and solvent structure. Hydrogen atom positions can readily be determined by neutron diffraction, and as such, neutron diffraction is an invaluable tool for elucidating molecular mechanisms. Joint refinement of neutron and X-ray diffraction data can lead to improved models compared with the use of neutron data alone and has now been incorporated into modern, maximum-likelihood based crystallographic refinement programs like CNS. Joint refinement has been applied to neutron and X-ray diffraction data collected on crystals of diisopropyl fluorophosphatase (DFPase), a calcium-dependent phosphotriesterase capable of detoxifying organophosphorus nerve agents. Neutron omit maps reveal a number of important features pertaining to the mechanism of DFPase. Solvent molecule W33, coordinating the catalytic calcium, is a water molecule in a strained coordination environment, and not a hydroxide. The smallest Ca-O-H angle is 53 degrees, well beyond the smallest angles previously observed. Residue Asp-229, is deprotonated, supporting a mechanism involving nucleophilic attack by Asp-229, and excluding water activation by the catalytic calcium. The extended network of hydrogen bonding interactions in the central water filled tunnel of DFPase is revealed, showing that internal solvent molecules form an important, integrated part of the overall structure.

AB Devitrification of bulk metallic glass leads to a novel microstructure, with high-density nanoscale crystalline precipitates evenly distributed in a glassy matrix. Significant chemical segregation is revealed at unprecedented detail by atom-probe tomography. This level of detail is crucial for understanding the interference peaks observed in small-angle X-ray and neutron scattering experiments, an unsolved mistery for over a decade.

AB The yield behavior in a freestanding sputter-deposited Cu/Nb multilayer with 30 nm nominal individual layer thickness has been investigated with in situ synchrotron x-ray diffraction during tensile loading. A pronounced elastic-plastic transition is observed with the fraction of plastically yielded grains increasing gradually with strain. Near synchronous yielding is observed in the Cu and Nb grains. The gradual progression in yield behavior is interpreted in terms of residual stresses, and elastic and plastic anisotropy.

AB We investigated the surface potential of the ferroelectric domains of the epitaxial PbTiO3 (PTO) films using both Kelvin probe and piezoresponse force microscopy. The surface potential changes as a function of applied biases suggested that the amount and sign of surface potentials depend on the correlation between polarization and screen charges. It also suggested that the trapped negative charges exist on the as-deposited PTO surfaces. Injected charges and their resultant surface potentials are investigated by grounded tip scans. The results unveiled the origin of surface potential changes during ferroelectric switching in the epitaxial PTO films.

Real-time observations of reactions indicate that unsteady (spinlike) reaction propagation leads to the formation of highly periodic surface morphologies with length scales ranging from 1 mu m to 1 mm. The characteristics of propagating spinlike reactions and corresponding reacted foil morphologies depend on the bilayer thickness of multilayer foils.

Specifically, geometric and material losses for these plasmonic structures are characterized using angular dependent transmission, normal incidence reflection, and angular dependent diffraction experiments, in addition to a crossed-polarizer transmission experiment. The optical properties of the samples as a function of engineered material losses are studied. Using this comprehensive approach to the characterization of the plasmonic structures, we are able to identify and isolate specific loss mechanisms, as well as identify the effect of free carriers on the optical properties of the structures.

AB The potential of NADH autofluorescence as an in vivo intrinsic optical signature to monitor tissue metabolism is well recognized and supported by experimental results mainly in animal models. In this work, we propose a non-contact implementation of this method using large area excitation and employing a normalization method to account for non-metabolic signal changes. Proof of principle in vivo experiments were carried out using an autofluorescence imaging experimental system and a rat renal ischemia model. A hand-held fiber-optic probe was utilized to test the ability of the signal normalization method to address operational conditions associated with the translation of this method to a clinical setting. Preliminary pre-clinical in vivo test of the probe system was carried out using the same rat model. (C) 2009 Optical Society of America

AB Thin films of the metal organic molecule bis(4-cyano-2,2,6,6-tetramethyl-3.5-heptanedionato)copper(II) (or Cu(CNdpm)(2)), (C(24)H(36)N(2)O(4)Cu, Cu(II)), deposited on ferromagnetic Co(111) at 40 K, exhibit a finite electron spin polarization. The spin polarization magnitude and sign for Cu(CNdpm)(2) deposited on Co(111) is coverage dependent, but deviates from the mean field expectations for a simple paramagnet oil a ferromagnetic Substrate. The spin asymmetry is seen to favor select molecular orbitals, consistent with the predicted single molecule density of states. The overlayer polarization observed indicates a strong influence of the ferromagnetic Co(111) substrate and some extra-molecular magnetic coupling. (C) 2008 Elsevier B.V. All rights reserved.

TI Search for pair production of second generation scalar leptoquarks
SO PHYSICS LETTERS B
LA English
DT Article
ID DETECTOR; COLLISIONS; TEV
AB We report on a search for the pair production of second generation scalar leptoquarks (LQ) in p (p) over bar collisions at the center of mass energy root s- = 1.96 TeV using a data set corresponding to an integrated luminosity of 1.0 fb(-1) collected with the D empty set experiment at the Fermilab Tevatron Collider. Topologies arising from the LQ (LQ) over bar -> mu q nu q and LQ (LQ) over bar -> mu q mu q decay modes are investigated. No excess of data over the standard model prediction is observed and upper limits on the leptoquark pair production cross section are derived at the 95% C.L. as a function of the leptoquark mass and the branching fraction beta for the decay LQ -> mu q. These are interpreted as lower limits on the leptoquark mass as a function of beta. For beta = 1 (0.5), scalar second generation leptoquarks with masses up to 316 GeV (270 GeV) are excluded.

AB Endocrine disruptors, including environmental estrogens, have been shown to induce heritable effects through both genetic and epigenetic mechanisms in mammals. Despite this information and the wealth of knowledge regarding the significant reproductive impacts endocrine disruptors impose on fishes, no studies have reported whether the observed effects are heritable. Without this information it is difficult to establish the long-term consequences for exposed populations. To determine potential consequences of long-term effects we must consider the possibility that induced reproductive defects in fishes may be heritable. Using rainbow trout (Oncorhynchus mykiss) as a model this study aims to determine whether a specific reproductive defect observed in 17 alpha-ethynylestradiol exposed male parents, diminished progeny survival, is heritable in the unexposed surviving F1 males. Semen was collected from anesthetized males of the F1 generation upon sexual maturation at two time-points, one year old precocious males and two years old males. In vitro fertilization was used to produce an F2 generation. F2 embryos were then analyzed for survival at 19 days post-fertilization (eye pigmentation) and the different treatment groups statistically compared to the controls. Analysis indicated that F2 offspring survival from F1 males propagated from both exposed and unexposed parents survive normally and no heritable effect was observed in males from the F1 generation for this specific reproductive defect. These results provide scope for the recovery of fish populations exposed to environmental estrogens should the contaminant be removed. (c) 2008 Elsevier B.V. All rights reserved.

AB We calculate the deviatoric and isotropic source components for 17 explosions at the Nevada Test Site, as well as 12 earthquakes and 3 collapses in the surrounding region of the western United States, using a regional time domain full waveform inversion for the complete moment tensor. The events separate into specific populations according to their deviation from a pure double-couple and ratio of isotropic to deviatoric energy. The separation allows for anomalous event identification and discrimination between explosions, earthquakes, and collapses. Confidence regions of the model parameters are estimated from the data misfit by assuming normally distributed parameter values. We investigate the sensitivity of the resolved parameters of an explosion to imperfect Earth models, inaccurate event depths, and data with low signal-to-noise ratio (SNR) assuming a reasonable azimuthal distribution of stations. In the band of interest (0.02-0.10 Hz) the source-type calculated from complete moment tensor inversion is insensitive to velocity model perturbations that cause less than a half-cycle shift (<5 s) in arrival time error if shifting of the waveforms is allowed. The explosion source-type is insensitive to an incorrect depth assumption (for a true depth of 1 km), and the goodness of fit of the inversion result cannot be used to resolve the true depth of the explosion. Noise degrades the explosive character of the result, and a good fit and accurate result are obtained when the signal-to-noise ratio is greater than 5. We assess the depth and frequency dependence upon the resolved explosive moment. As the depth decreases from 1 km to 200 m, the isotropic moment is no longer accurately resolved and is in error between 50 and 200%. However, even at the most shallow depth the resultant moment tensor is dominated by the explosive component when the data have a good SNR.

AB gamma-Secretase, an integral membrane protein complex, catalyzes the intramembrane cleavage of the beta-amyloid precursor protein (APP) during the neuronal production of the amyloid beta-peptide. As such, the protease has emerged as a key target for developing agents to treat and prevent Alzheimer's disease. Existing biochemical studies conflict on the oligomeric assembly state of the protease complex, and its detailed structure is not known. Here, we report that purified active human gamma-secretase in digitonin has a total molecular mass of similar to 230 kDa when measured by scanning transmission electron microscopy. This result supports a complex that is monomeric for each of the four component proteins. We further report the three-dimensional structure of the gamma-secretase complex at 12 angstrom resolution as obtained by cryoelectron microscopy and single-particle image reconstruction. The structure reveals several domains on the extracellular side, three solvent-accessible low-density cavities, and a potential substrate-binding surface groove in the transmembrane region of the complex.

TI Search for a Higgs Boson Decaying to Two W Bosons at CDF
SO PHYSICAL REVIEW LETTERS

DT Article
ID Z-GAMMA PRODUCTION; HADRON COLLIDERS; STANDARD MODEL
AB We present a search for a Higgs boson decaying to two W bosons in p (p) over bar collisions at root s = 1.96 TeV center-of-mass energy. The data sample corresponds to an integrated luminosity of 3.0 fb(-1) collected with the CDF II detector. We find no evidence for production of a Higgs boson with mass between 110 and 200 GeV/c(2), and determine upper limits on the production cross section. For the mass of 160 GeV/c(2), where the analysis is most sensitive, the observed (expected) limit is 0.7 pb (0.9 pb) at 95% Bayesian credibility level which is 1.7 (2.2) times the standard model cross section.

AB The mixed-valent compound EuNi2P2 was studied by photoemission. Observed splittings and dispersions of the Eu 4f(6) final state close to energy crossings of the Eu 4f and Ni 3d states are explained in terms of hybridization by a momentum and energy dependence of the electron hopping matrix element. These data obtained for a system with more than one 4f electron (hole) show that dispersions and hybridization gaps related to Kondo and heavy-fermion behavior can be found in other rare-earth-metal compounds apart from Ce and Yb-based ones.

TI Density-Functional Calculations of the Structure of Near-Surface Oxygen
Vacancies and Electron Localization on CeO2(111)
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID LOW-INDEX SURFACES; CERIA; OXIDE
AB One of the most topical issues surrounding oxygen vacancies on CeO2(111) is the relative stability of surface and subsurface defects. Using density-functional theory (DFT) with the HSE06 (Heyd-Scuseria-Ernzerhof) hybrid functional as well as the DFT+U approach (where U is a Hubbard-like term describing the on-site Coulomb interactions), we find subsurface vacancies with (2x2) periodicity to be energetically more favorable by 0.45 (HSE06), 0.47 [PBE+U (Perdew-Burke-Ernzerhof functional)], and 0.22 eV [LDA+U (local density approximation)]. The excess electrons localize not on Ce ions which are the nearest neighbor to the defect as priorly suggested, but instead on those that are next-nearest neighbors. The excess-electron distribution and the preference for subsurface vacancies are explained in terms of defect-induced lattice relaxation effects.

MOLECULES; IONIZATION; ACCURACY; D-3(+)
AB A simple analytical approach is presented to describe the dissociative recombination (DR) of an electron with H-3(+) and its isotopomers. The principal assumption is that resonant capture mediated by the Jahn-Teller interaction dominates the cross section. The only input required comes from spectroscopic data on the 3pE' Rydberg state of H-3 and the nu(2) vibrational frequencies of H-3(+) and its isotopomers. The approach provides an independent prediction of the low-energy DR cross sections and rates, and is in good agreement with the latest experimental and theoretical determinations.

TI Effects of Mass Ablation on the Scaling of X-Ray Power with Current in
Wire-Array Z Pinches
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID IMPLOSION DYNAMICS; MAGNETOHYDRODYNAMIC SIMULATIONS
AB X-ray production by imploding wire-array Z pinches is studied using radiation magnetohydrodynamics simulation. It is found that the density distribution created by ablating wire material influences both x-ray power production, and how the peak power scales with applied current. For a given array there is an optimum ablation rate that maximizes the peak x-ray power, and produces the strongest scaling of peak power with peak current. This work is consistent with trends in wire-array Z pinch x-ray power scaling experiments on the Z accelerator.

AB Radiative hydrodynamics simulations of ignition experiments show that energy transfer between crossing laser beams allows tuning of the implosion symmetry. A new full-scale, three-dimensional quantitative model has been developed for crossed-beam energy transfer, allowing calculations of the propagation and coupling of multiple laser beams and their associated plasma waves in ignition hohlraums. This model has been implemented in a radiative-hydrodynamics code, demonstrating control of the implosion symmetry by a wavelength separation between cones of laser beams.

ID SUPERFLUID; SYSTEM
AB We investigate the behavior of impurity fields immersed in a larger condensate field in various dimensions. We discuss the localization of a single impurity field within a condensate and note the effects of surface energy. We derive the functional form of the attractive condensate-mediated interaction between two impurities. Generalizing the analysis to N impurity fields, we show that within various parameter regimes a crystal of impurity fields can form spontaneously in the condensate. Finally, the system of condensate and crystallized impurity structure is shown to have nonclassical rotational inertia, which is characteristic of superfluidity; i.e., the system can be seen to exhibit supersolid behavior.

SYSTEMS; FLUCTUATIONS; POLARITONS; GASES
AB Electron-hole bilayers are expected to make a transition from a pair of weakly coupled two-dimensional systems to a strongly coupled exciton system as the barrier between the layers is reduced. Coulomb drag measurements on devices with a 30 nm barrier are consistent with two weakly coupled 2D Fermi systems where the drag decreases with temperature. For a 20 nm barrier, however, we observe an increase in the drag resistance as the temperature is reduced when a current is driven in the electron layer and voltage measured in the hole layer. These results indicate the onset of strong coupling possibly due to exciton formation or phenomena related to exciton condensation.

TI Extracting Primordial Non-Gaussianity without Cosmic Variance
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID HALO BIAS; STOCHASTICITY
AB Recent work has emphasized the possibility to probe non-Gaussianity of local type by measuring the power spectrum of highly biased tracers of large scale structure on very large scales. This method is limited by the cosmic variance, by the finite number of structures on the largest scales, and by the partial degeneracy with other cosmological parameters that can mimic the same effect. We propose an alternative method based on the fact that on large scales, halos are linearly biased, but not stochastic, tracers of dark matter: by correlating a highly biased tracer of large scale structure against an unbiased tracer, one eliminates the cosmic variance error, which can lead to a significant increase in signal to noise. For an ideal survey out to z similar to 2, the error reduction can be as large as a factor of 7, which should guarantee a detection of non-Gaussianity from an all-sky survey of this type.

AB We experimentally demonstrate a chiral metamaterial exhibiting negative refractive index at terahertz frequencies. The presence of strong chirality in the terahertz metamaterial lifts the degeneracy for the two circularly polarized waves and allows for the achievement of negative refractive index without requiring simultaneously negative permittivity and negative permeability. The realization of terahertz chiral negative index metamaterials offers opportunities for investigation of their novel electromagnetic properties, such as negative refraction and negative reflection, as well as important terahertz device applications.

TI Complete Genome Sequence of the Aerobic CO-Oxidizing Thermophile
Thermomicrobium roseum
SO PLOS ONE
LA English
DT Article
AB In order to enrich the phylogenetic diversity represented in the available sequenced bacterial genomes and as part of an "Assembling the Tree of Life" project, we determined the genome sequence of Thermomicrobium roseum DSM 5159. T. roseum DSM 5159 is a red-pigmented, rod-shaped, Gram-negative extreme thermophile isolated from a hot spring that possesses both an atypical cell wall composition and an unusual cell membrane that is composed entirely of long-chain 1,2-diols. Its genome is composed of two circular DNA elements, one of 2,006,217 bp (referred to as the chromosome) and one of 919,596 bp (referred to as the megaplasmid). Strikingly, though few standard housekeeping genes are found on the megaplasmid, it does encode a complete system for chemotaxis including both chemosensory components and an entire flagellar apparatus. This is the first known example of a complete flagellar system being encoded on a plasmid and suggests a straightforward means for lateral transfer of flagellum-based motility. Phylogenomic analyses support the recent rRNA-based analyses that led to T. roseum being removed from the phylum Thermomicrobia and assigned to the phylum Chloroflexi. Because T. roseum is a deep-branching member of this phylum, analysis of its genome provides insights into the evolution of the Chloroflexi. In addition, even though this species is not photosynthetic, analysis of the genome provides some insight into the origins of photosynthesis in the Chloroflexi. Metabolic pathway reconstructions and experimental studies revealed new aspects of the biology of this species. For example, we present evidence that T. roseum oxidizes CO aerobically, making it the first thermophile known to do so. In addition, we propose that glycosylation of its carotenoids plays a crucial role in the adaptation of the cell membrane to this bacterium's thermophilic lifestyle. Analyses of published metagenomic sequences from two hot springs similar to the one from which this strain was isolated, show that close relatives of T. roseum DSM 5159 are present but have some key differences from the strain sequenced.

AB The ability to regulate how molecular chirality of enantiomeric amino acids operates in biological systems constitutes the basis of drug design for specific targeting. We report herein a nanoparticle-based strategy to regulate interparticle chiral recognition of enantiomers using enantiomeric cysteines (L and D) and gold nanoparticles as a model system. A key element of this strategy is the creation of a nanoscale environment either favoring or not favoring the preferential configuration of the pairwise zwitterionic dimerization of the enantiomeric cysteines adsorbed on gold nanoparticles as a footprint for interparticle chiral recognition. This recognition leads to interparticle assembly of the nanoparticles which is determined by the change in the nanoparticle surface plasmonic resonance. While the surface density and functionality of cysteines on gold nanoparticles are independent of chirality, the interparticle chiral recognition is evidenced by the sharp contrast between the interparticle homochiral and heterochiral assembly rates based on a first-order kinetic model. The structural properties for the homochiral and heterochiral assemblies of nanoparticles depend on the particle size, the cysteine chirality, and other interparticle binding conditions. The structural and thermodynamic differences between the homochiral and heterochiral interactions for the interparticle assemblies of nanoparticles were not only substantiated by spectroscopic characterizations of the adsorbed cysteine species but also supported by structures and enthalpies obtained from preliminary density functional theory calculations. The experimental-theoretical correlation between the interparticle reactivity and the enantiomeric ratio reveals that the chiral recognition is tunable by the nanoscale environment, which is a key feature of the nanoparticle-regulation strategy for the interparticle chiral recognition.

AB Copper and zinc oxide based catalysts prepared by coprecipitation were promoted with palladium and ZrO2, and their activity and selectivity for methanol oxidative reforming was measured and characterized by N2O decomposition, X-ray absorption spectroscopy, BET, X-ray photoelectron spectroscopy, X-ray diffraction, and temperature programmed reduction. Addition of ZrO2 increased copper dispersion and surface area, with little effect on activity, while palladium promotion significantly enhanced activity with little change of the catalytic structure. A catalyst promoted with both ZrO2 and palladium yielded hydrogen below 150 degrees C. EXAFS results under reaction conditions showed that the oxidation state of copper was influenced by palladium in the catalyst bulk. A palladium promoted catalyst contained 90% Cu degrees, while the copper in an unpromoted catalyst was 100% Cu1+ at the same temperature. Palladium preferentially forms an unstable alloy with copper instead of zinc during reduction, which persists during reaction regardless of copper oxidation state. A 100-h time on stream activity measurement showed growth in copper crystallites and change in copper oxidation state resulting in decreasing activity and selectivity. A kinetic model of the reaction pathway showed that palladium and ZrO2 promoters lower the activation energy of methanol combustion and steam reforming reactions. (C) 2008 Elsevier B.V.

AB In this article, we analyze some residual-based stabilization techniques for the transient Stokes problem when considering anisotropic time-space discretizations. We de. ne an anisotropic time-space discretization as a family of time-space partitions that does not satisfy the condition h(2) <= C delta t with C uniform with respect to h and delta t. Standard residual-based stabilization techniques are motivated by a multiscale approach, approximating the effect of the subscales onto the large scales. One of the approximations is to consider the subscales quasi-static (neglecting their time derivative). It is well known that these techniques are unstable for anisotropic time-space discretizations. We show that the use of dynamic subscales (where the subscales time derivatives are not neglected) solves the problem, and prove optimal convergence and stability results that are valid for anisotropic time-space discretizations. Also the improvements related to the use of orthogonal subscales are addressed. (C) 2008 Elsevier Inc. All rights reserved.

ID BOOLEAN NETWORKS; LOGIC REGRESSION; GRAPHICAL MODELS
AB Motivation: Combinatorial effects, in which several variables jointly influence an output or response, play an important role in biological systems. In many settings, Boolean functions provide a natural way to describe such influences. However, biochemical data using which we may wish to characterize such influences are usually subject to much variability. Furthermore, in high-throughput biological settings Boolean relationships of interest are very often sparse, in the sense of being embedded in an overall dataset of higher dimensionality. This motivates a need for statistical methods capable of making inferences regarding Boolean functions under conditions of noise and sparsity.
Results: We put forward a statistical model for sparse, noisy Boolean functions and methods for inference under the model. We focus on the case in which the form of the underlying Boolean function, as well as the number and identity of its inputs are all unknown. We present results on synthetic data and on a study of signalling proteins in cancer biology.

AB Matrix metalloproteinase-14 (MT1-MMP or MMP-14) is a membrane-associated protease implicated in a variety of tissue remodeling processes and a molecular hallmark of select metastatic cancers. The ability to detect MMP-14 in vivo would be useful in studying its role in pathologic processes and may potentially serve as a guide for the development of targeted molecular therapies. Four MMP-14 specific probes containing a positively charged cell penetrating peptide (CPP) d-arginine octamer (r(8)) linked with a MMP-14 peptide substrate and attenuating sequences with glutamate (8e, 4e) or glutamate-glycine (4eg and 4egg) repeating units were modeled using an AMBER force field method. The probe with 4egg attenuating sequence exhibited the highest CPP/attenuator interaction, predicting minimized cellular uptake until cleaved. The in vitro MMP-14-mediated cleavage studies using the human recombinant MMP-14 catalytic domain revealed an enhanced cleavage rate that directly correlated with the linearity of the embedded peptide substrate sequence. Successful cleavage and uptake of a technetium-99m labeled version of the optimal probe was demonstrated in MMP-14 transfected human breast cancer cells. Two-fold reduction of cellular uptake was found in the presence of a broad spectrum MMP inhibitor. The combination of computational chemistry, parallel synthesis and biochemical screening, therefore, shows promise as a set of tools for developing new radiolabeled probes that are sensitive to protease activity.

AB Specific inhibitors of mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) kinase (MEK) have been developed that efficiently inhibit the oncogenic RAF-MEK-ERK pathway. We used a systems-based approach to identify breast cancer subtypes particularly susceptible to MEK inhibitors and to understand molecular mechanisms conferring resistance to such compounds. Basal-type breast cancer cells were found to be particularly susceptible to growth inhibition by small-molecule MEK inhibitors. Activation of the phosphatidylinositol 3-kinase (PI3K) pathway in response to MEK inhibition through a negative MEK-epidermal growth factor receptor-PI3K feedback loop was found to limit efficacy. Interruption of this feedback mechanism by targeting MEK and PI3K produced synergistic effects, including induction of apoptosis and, in some cell lines, cell cycle arrest and protection from apoptosis induced by proapoptotic agents. These findings enhance our understanding of the interconnectivity of oncogenic signal transduction circuits and have implications for the design of future clinical trials of MEK inhibitors in breast cancer by guiding patient selection and suggesting rational combination therapies.

AB Repeating earthquakes (REs) are sequences of events that have virtually identical waveforms and are interpreted to represent fault asperities driven to failure by loading from aseismic creep on the surrounding fault surface at depth. To investigate the postseismic deformation after the 1984 M6.2 Morgan Hill earthquake, we identify RE sequences occurring on the central Calaveras fault between 1984 and 2005 using a combination of cross-correlation and spectral coherence techniques. Both the accelerated slip transients due to the earthquake as well as the return to interseismic background creep rates can be imaged from Our dataset. A comparison between the regions of the fault that ruptured coseismically and the locations of the REs show that REs preferentially Occur in areas adjacent to the coseismic rupture. Using calculated RE-derived Subsurface slip distributions at 6 months and 18 months after the mainshock, we predict surface electronic distance meter (EDM) line length changes between stations near the Morgan Hill rupture at-ea. The RE-derived slip model underpredicts a subset of the observed line-length changes. Inclusion of transient aseismic slip below the seismogenic zone is needed to better match the measured Surface deformation. (c) 2008 Elsevier B,V. All rights reserved.

AB Pleistocene uplift of the Chilean coast is recorded by the formation of wave-cut platforms resulting from marine erosion during sea-level highstands. In the Altos de Talinay area (similar to 31 degrees S). we have identified a sequence of 5 wave-cut platforms. Using in situ produced Be-10 exposure ages we show that these platforms were formed during interglacial periods at 6, 122, 232, 321 and 690 ka. These ages correspond to marine isotopic stages (MIS) or substages (MISS) 1, 5e, 7e, 9c and 17. Shoreline angle elevations used in conjunction with our chronology of wave-cut platform formation. illustrate that Surface uplift rates vary from 103 69 mm/ka between 122 and 6 ka, to 1158 +/- 416 mm/ka between 321 and 232 ka. The absence of preserved platforms related to the MIS 11, 13 and 15 highstands likely reflects slow uplift rates during these times. We Suggest that since 700 ka, the Altos de Talinay area was predominantly uplifted during 2 short periods following MIS 17 and MISS 9c. This episodic uplift of the Chilean coast in the Pleistocene may result from subduction related processes, such as pulses of tectonic accretion at the base of the forearc wedge.

AB Here we examine Fe speciation within Fe-encrusted biofilms formed during 2-month seafloor incubations of sulfide mineral assemblages at the Main Endeavor Segment of the Juan de Fuca Ridge. The biofilms were distributed heterogeneously across the surface of the incubated sulfide and composed primarily of particles with a twisted stalk morphology resembling those produced by some aerobic Fe-oxidizing microorganisms. Our objectives were to determine the form of biofilm-associated Fe, and identify the sulfide minerals associated with microbial growth. We used micro-focused synchrotron-radiation X-ray fluorescence mapping (mu XRF), X-ray absorption spectroscopy (mu EXAFS), and X-ray diffraction (mu XRD) in conjunction with focused ion beam (FIB) sectioning, and high resolution transmission electron microscopy (HRTEM). The chemical and mineralogical composition of an Fe-encrusted biofilm was queried at different spatial scales, and the spatial relationship between primary sulfide and secondary oxyhydroxide minerals was resolved. The Fe-encrusted biofilms formed preferentially at pyrrhotite-rich (Fe(1-x)S, 0 <= x <= 0.2) regions of the incubated chimney sulfide. At the nanometer spatial scale, particles within the biofilm exhibiting lattice fringing and diffraction patterns consistent with 2-line ferrihydrite were identified infrequently. At the micron spatial scale, Fe mu EXAFS spectroscopy and mu XRD measurements indicate that the dominant form of biofilm Fe is a short-range ordered Fe oxyhydroxide characterized by pervasive edge-sharing Fe-O(6) octahedral linkages. Double corner-sharing Fe-O(6) linkages, which are common to Fe oxyhydroxide mineral structures of 2-line ferrihydrite, 6-line ferrihydrite, and goethite, were not detected in the biogenic iron oxyhydroxide (BIO). The suspended development of the BIO mineral structure is consistent with Fe(III) hydrolysis and polymerization in the presence of high concentrations of Fe-complexing ligands. We hypothesize that microbiologically produced Fe-complexing ligands may play critical roles in both the delivery of Fe(II) to oxidases, and the limited Fe(III) oxyhydroxide crystallinity observed within the biofilm. Our research provides insight into the structure and formation of naturally occurring, microbiologically produced Fe oxyhydroxide minerals in the deep-sea. We describe the initiation of microbial seafloor weathering, and the morphological and mineralogical signals that result from that process. Our observations provide a starting point from which progressively older and more extensively weathered seafloor sulfide minerals may be examined, with the ultimate goal of improved interpretation of ancient microbial processes and associated biological signatures.

AB Lunar Mg-suite norite 78238 was dated using the Sm-Nd, Rb-Sr. and U-Pb isotopic systems in order to constrain the age of lunar magma ocean solidification and the beginning of Mg-suite magmatism, as well as to provide a direct comparison between the three isotopic systems. The Sm-Nd isotopic system yields a crystallization age for 78238 of 4334 37 Ma and an initial epsilon(143)(Nd) value of -0.27 +/- 0.74. The age-initial epsilon(143)(Nd) systematics of a variety of KREEP-rich samples, including 78238 and other Mg-suite rocks, KREEP basalts, and olivine cumulate NWA 773, suggest that lunar differentiation was completed by 4492 +/- 61 Ma assuming a Chondritic Uniform Reservoir bulk composition for the Moon. The Rb-Sr isotopic systematics of 78238 were disturbed by post-crystallization processes. Nevertheless, selected data points yield two Rb-Sr isochrons. One is concordant with the Sm-Nd crystallization age, 4366 +/- 53 Ma. The other is 4003 +/- 95 Ma and is concordant with an Ar-Ar age for 78236. The (207)pb-(206)Pb age of 4333 +/- 59 Ma is concordant with the Sm-Nd age. The U-Pb isotopic systematics of 78238 yield linear arrays equivalent to younger ages than the Pb-Pb system, and may reflect fractionation of U and Pb during sample handling. Despite the disturbed nature of the U-Pb systems, a time-averaged mu ((238)U/(204)Pb) value of the source can be estimated at 27 +/- 30 from the Pb-Pb isotopic systematics. Because KREEP-rich samples are likely to be derived from source regions with the highest U/Pb ratios, the relatively low mu value calculated for the 78238 source suggests the bulk Moon does not have an exceedingly high mu value.

AB Muztag Ata and Kongur Shan massifs represent a significant area of anomalously high topography at the northwestern end of the Tibetan Plateau, rising to >7500 m above sea-level (asl) from the plateau that has an average elevation of similar to 3500 m asl. These massifs provide an excellent opportunity to test geomorphic concepts, such as the glacial buzz-saw model. Using remote sensing, digital elevation modeling, field mapping and terrestrial cosmogenic nuclide (TCN) methods, the massifs were examined to determine the relative importance of tectonics and geomorphic processes in shaping the regional landscape and to provide a framework for testing geomorphic models. The gneiss domes that underlie the peaks are the result of exhumation along the Kongur detachment fault that has unroofed the massifs at a rate of between 4-6 km/Ma over the last few million years. This has resulted in rapid uplift and active seismicity, which is exemplified by the numerous fresh fault scarps throughout the region and large historic earthquakes. The geomorphic system is dominated by glaciation and the region contains extensive successions of moraines and paraglacial landforms, including fans, terraces and landslides. Glaciers have oscillated considerably throughout the latter part of the Quaternary, and three major glacier stages are recognized (Karasu [oldest], Olimde and Subaxh [youngest] glacial stage) that include at least 10 smaller glacial advance. The style of glaciation has changed over time from expanded ice caps to piedmont glaciers to valley and cirque glaciers. This possibly reflects a change in climate and/or topographic constraints as the massifs grew and became incised. The topography and glaciers in the region vary across the massifs divided by a broadly N-S trending high ridge and watershed. The western portion, situated upwind (the stoss slopes) of the mid-latitude westerlies, that bring moisture to the region, has gentle high topography and small valley glaciers. in contrast, on the eastern leeward slopes, gradients are higher and long debris-covered valley glaciers are present. The hypsometry of the region indicate two peaks in the distribution frequency of elevation (3600-4100 m and 4400-4800 m asl). These two elevation zones are consistent in space with the former equilibrium-line altitudes during the Olimde and Subaxh glacial stages and suggest that glacial erosion (most effective at the ELA) has helped control topography. This observation supports the glacial buzz-saw hypothesis, which argues that glaciers determine hypsometry by means of rapid surface erosion. Based on TCN methods, basin-wide rates of erosion range from similar to 0.1 to 1.4 km/Ma and are five to ten times lower than the unroofing rate of both massifs. The discrepancy over different time scales suggests that initial unroofing was produced by abrupt tectonic uplift and that the unroofing of the massifs has continued at a slower pace during the Late Quaternary.

AB The Central Karakoram, which includes K2 in Pakistan, is one of the most rapidly rising areas on Earth and exhibits complex topography and extreme relief Impressive valley fills and glacial landforms are present throughout the valleys. The dynamics of landscape evolution of the region are currently not well understood. Consequently, the landforms were mapped and assessed in the Skardu, Shigar, and Braldu valleys, to elucidate the spatio-temporal scale dependencies of surface processes active in the region. These valleys were examined using geomorphic field methods, remote sensing, geomorphometry, and terrestrial cosmogenic nuclides (TCNs) surface exposure dating. The glaciers in this region have oscillated considerably throughout the Late Quaternary, and four glacial stages have been recognized including at least six glacial advances. Surface processes readjusted after glacier retreat, and ubiquitous mass movements and catastrophic landsliding transported material from steep slopes to valley bottoms, while glaciofluvial meltwater and glacier outburst floods redistributed sediment down valley. Glacier geochronology and late Holocene ages of the outburst flood deposits indicate that landscape evolution has been dominated by glaciation and paraglaciation during the late Quaternary.

AB We present an expression developed for calculating an atomic-scale deformation gradient within atomistic simulations. This expression is used to analyze the deformation fields for a one-dimensional atomic chain, a biaxially stretched thin film containing a surface ledge, and a FCC metal subject to indentation loading from a nanometer-scale indenter. The analyses presented show that the metric established here is consistent with the continuum mechanical concept of deformation gradient (which is known to have a zero curl for compatible deformations) in most instances. However, our metric does yield non-zero values of curl for atoms near loaded geometric inhomogeneities, such as those that form the ledges themselves and those beneath or adjacent to the indentation contact region. Also, we present expressions for higher order gradients of the deformation field and discuss the requirements for their calculation. These expressions are necessary for linking atomistic simulation results with advanced continuum mechanics theories such as strain gradient plasticity, thereby enabling fundamental, atomic-scale information to contribute to the formulation and parameterization of such theories.

ID BIREFRINGENT WEDGE; GRADIENTS
AB To aid in evaluating spatial and spectral imaging abilities of any imaging spectroradiometer system, we developed a spectral intensity gradient standard based on the behavior of a birefringent wedge imaged between cross polarizers. By comparing calculated with observed images of the wedge, a chromatic scrambling kernel was measured to generally estimate chromatic aberrations in any spectral imaging optical system. This technique provides a quantitative method to compare spectral imaging quality of different optical systems and also provides a quick test for severe misalignments in the optical path. Applying this method to the spectroradiometric measurement of temperature and temperature gradients in the laser-heated diamond cell, the observed scrambling kernel is used to infer original hotspot information from measured behavior, to provide a quantitative evaluation of the ability to measure a temperature gradient in any spectral system, and to yield an objective determination of precision of spectroradiometric temperature measurements. The birefringent wedge method and its application described in this paper are simple and inexpensive enough to be used on any spectroradiometric system.

AB It is demonstrated that both the nucleation field and the irreversible switching field of Sm2Co7/Fe exchange spring bilayers is decreased by means of 10 keV He ion irradiation. The reduction is attributed to interfacial mixing and irradiation induced softening of the hard magnetic layer. By lowering the energy to 0.8 keV the ions do not penetrate the hard magnetic layer and, consequently, no softening is observed. However, although irradiation induced interfacial mixing is still present it is not large enough to create a graded interface layer and the nucleation field decreases. In contrast, conventional annealing under appropriate conditions leads to an increase in the nucleation field. This distinct discrepancy can be explained by detailed investigation of the layer structure by x-ray reflectivity measurements.

AB Electron scattering at interfaces between metals and dielectrics is a major concern in thermal boundary conductance studies. This aspect of energy transfer has been extensively studied and modeled on long time scales when the electrons and phonons are in equilibrium in the metal film. However, there are conflicting results concerning electron-interface scattering and energy transfer in the event of an electron-phonon nonequilibrium, specifically, how this mode of energy transfer affects the electron cooling during electron-phonon nonequilibration. Transient thermoreflectance (TTR) experiments utilizing ultrashort pulsed laser systems can resolve this electron-phonon nonequilibrium, and the thermophysical property relating rate of equilibration to electron-phonon scattering events G can be quantified. In this work, G in Au films of varying thicknesses are measured with the TTR technique. At large fluences (which result in high electron temperatures), the measured G is much larger than predicted from traditional models. This increase in G increases as the film thickness decreases and shows a substrate dependency, with larger values of G measured on more conductive substrates. The data suggest that in a highly nonequilibrium system, there could be some thermal energy lost to the underlying substrate, which can affect G.

AB Molecular dynamics simulations were utilized to test the reliability of strain values obtained from diffraction data for noncrystalline alloys. We found that in the case of a one-component system, the strain value obtained from the pair correlation functions underestimates the actual value because of a small degree of atomic relaxations, which minimize the effects of the applied deformation. In the case of multicomponent systems, the different pairs are affected by applied deformation to different extents; moreover, this implies that the strain value determined from diffraction data should depend on the type of scattering.

AB We demonstrate that x-ray absorption spectroscopy (XAS) can be used as an unconventional characterization technique to determine the proportions of different crystal phases in polymorphic samples. As an example, we show that ratios of anatase and rutile phases contained in the TiO2 samples obtained by XAS are in agreement with conventional x-ray diffraction (XRD) measurements to within a few percent. We suggest that XAS measurement is a useful and reliable technique that can be applied to study the phase composition of highly disordered or nanoparticle polymorphic materials, where traditional XRD technique might be difficult.

AB Intense pulsed D-D neutron emission with rates of >10(10) n/s during the pulse, pulse widths of approximately hundreds of nanoseconds and neutron yields of greater than 10 000 per pulse, are demonstrated in a compact pyroelectric accelerator. The accelerator consists of a small pyroelectric LiTaO(3) crystal that provides the accelerating voltage and an independent compact spark plasma ion source. The crystal voltage versus temperature is characterized and compares well with theory. Results show neutron output per pulse that scales with voltage as V(similar to 1.7). These neutron yields match a simple model of the system at low voltages but are lower than predicted at higher voltages due to charge losses not accounted for in the model. Interpretation of the data against modeling provides understanding of the accelerator and in general pyroelectric LiTaO(3) crystals operated as charge limited negative high voltage targets. The findings overall serve as the proof of principle and basis for pyroelectric neutron generators that can be pulsed, giving peak neutron rates orders of magnitude greater than previous work and notably increase the potential applications of pyroelectric based neutron generators.

AB Stimulated by the recent observation of pi-pi interactions between C(60) and corannulene subunits in a molecular tweezer arrangement (J Am Chem Soc 2007, 129, 3842), a density functional theory Study was performed to analyze the electronic structure and properties of various noncovalent corannulene complexes. The theoretical approach is first applied to corannulene complexes with a series of benchmark molecules (CH(4), NH(3), and H(2)O) using several new-generation density functionals. The performance of nine density functionals, illustrated by computing binding energies of the corannulene complexes, demonstrates that Zhao and Truhlar's MPWB1K and M05-2X functionals provide energies similar to that obtained at the SCS-MP2 level. In contrast, most of the other popular density functionals fail to describe this noncovalent interaction or yield purely repulsive interactions. Further investigations with the M05-2X functional show that the binding energy of C(60) with corannulene subunits in the relaxed molecular receptor clip geometry is -20.67 kcal/mol. The results of this calculation further support the experimental interpretation of pure pi-pi interactions between a convex fullerene and the concave surfaces of two corannulene subunits.

AB Ag presentation within the regional lymph node is crucial for the initiation of CD8(+) T cell responses following viral infection. The magnitude and quality of the CD8(+) T cell response are regulated by the interplay between the size of the APC population and duration of Ag presentation. To understand how these parameters are finely regulated during an immune response, we have investigated the dynamics of Ag presentation in influenza A virus and HSV-1 infection. In both infections, APC production was calculated to occur over the first few days of infection, after which there was slow exponential decay over a period of up to 2 wk. This production rate is most likely determined by the Ag availability and recruitment and/or maturation rate of dendritic cells. APC production was found to closely parallel lymph node cell recruitment in both infections. This was greatest in the first 6 It of infection for HSV and over the second and third day for influenza. In HSV infection, the peak production also coincides with peak viral levels. By contrast, in influenza infection, APC production ceased between the third and fourth day despite the presence of high levels of virus until 5 days after infection. These analyses demonstrate that two quite different self-limiting infections generate the APC necessary to drive T cell responses early in infection at different rates. Understanding how such contrasting kinetics of Ag presentation impacts on the growth and size of developing protective T cell populations has important implications for the design of vaccines and immunotherapies.

AB Electronic structure of disordered semiconducting conjugated polymers was studied. Atomic structure was found from a classical molecular dynamics simulation, and the charge patching method was used to calculate the electronic structure with the accuracy similar to the one of density functional theory in local density approximation. The total density of states, the local density of states at different points in the system, and the wave functions of several states around the gap were calculated in the case of poly(3-hexylthiophene) (P3HT) and polythiophene (PT) systems to gain insight into the origin of disorder in the system, the degree of carrier localization, and the role of chain interactions. The results indicated that disorder in the electronic structure of alkyl-substituted polythiophenes comes from disorder in the conformation of individual chains, while in the case of polythiophene there is ail additional contribution due to disorder in the electronic coupling between the chains. Each of the first several wave functions in the conduction and valence band of P3HT is localized over several rings of a single chain. It was shown that the localization can be caused in principle both by ring torsions and chain bending; however, the effect of ring torsions is much stronger. PT wave functions are more complicated due to larger interchain electronic coupling and are not necessarily localized on a single chain.

AB We report the results of a combined experimental and theoretical investigation of the reaction of molecular oxygen with a partially hydroxylated TiO2 (110) surface. The consecutive steps of both primary and secondary site-specific reactions have been tracked with high-resolution scanning tunneling microscopy (STM). We have directly imaged stable, adsorbed hydroperoxyl (HO2) species, which is believed to be a key intermediate in many heterogeneous photochemical processes but generally metastable and "elusive" until now. We also found terminal hydroxyl groups, which are another critical but never previously directly observed intermediates. Conclusive evidence that O-2 reacts spontaneously with a single bridging OH group as an initial reaction step is provided. The experimental results are supported by density functional theory (DFT) calculations that have determined the energies and configurations of these species. Reported observations provide a base for a consistent description of the elementary reaction steps and offer molecular-level insight into the underlying reaction mechanisms. The results are also expected to have important implications for various catalytic systems involving the interconversion of O-2 and H2O.

AB We have examined the local electronic behavior of titanocene chloride dimer molecules, [CP(2)TiCl](2) (CP = CA), on Au(111) using both scanning tunneling microscopy (STM) and density functional theory (DFT). Isolated dimeric molecules are seen to decorate gold step edges at low surface coverages and two coexisting monolayer phases are observed at higher coverages. Differential conductance STM spectroscopy shows a variety of structure in the electronic local density of states for single molecules and for the two monolayer phases. DFT calculations modeling an isolated titanocene chloride dimer do not reproduce the wide variations seen in spectral density, suggesting that a fraction of titanocene dimers break apart into metallocene monomers on the Au(111) surface and display magnetic behavior.

AB The reaction of NO2 with BaO (0.15-2 ML and >30 ML)/Al2O3(12 ML)/NiAl(110) model NOx storage materials was studied. A thick (similar to 12 ML), ordered Al2O3 film was prepared as the support oxide on a NiAl(110) substrate to minimize the effect of the intermixing between the two oxide phases (BaO and Al2O3) on the NO, chemistry of BaO. The growth of a thick alumina film, prepared by atomic oxygen deposition onto NiAl(110), follows a layer-by-layer growth mode, and the resulting film is much more stable when exposed to NO2 than the ultrathin alumina films studied before. The interaction of NO2 with the model NOx storage systems at low coverages of BaO shows behaviors fundamentally different from a thick BaO film, as nitrite species form at low exposures of NO2, followed by nitrate formation at high NO2 exposures: In contrast, on the thick BaO layer, nitrite-nitrate ion pairs form at 300 K under UHV conditions (P-NO2 similar to 1 X 10(-9) Tort). However, at elevated NO2 pressures (>= 1 x 10(-5) Tort), the thick BaO film is gradually converted into amorphous Ba(NO3)(2) at 300 K. Raising the temperature of the samples with circle minus(BaO) > 1 ML after NO2 exposure (in the absence of gas phase NO:2) leads to the phase transformation of the amorphous Ba(NO3)(2) layer into crystalline Ba(NO3)(2) particles in the temperature range of 500-600 K. No phase transformation is observed in samples with circle minus(BaO) < 1 ML.

AB Partially disulfonated hydroquinone (HQ)-based poly(arylene ether sulfone) random copolymers were synthesized and characterized for application as proton exchange membranes. The copolymer composition was varied in the degree of disulfonation. The copolymers were characterized by (1)H NMR, Differential Scanning Calorimetry (DSC), and other analytical techniques. The copolymer with a 25% degree of disulfonation showed the best balance between water uptake and proton conductivity. The copolymers showed substantially reduced methanol permeability compared with Nafion (R) and satisfactory direct methanol fuel cell performance. The methanol selectivity improved significantly in comparison to Nafion (R) 117. At a given ionic composition, the HQ-based system showed higher water uptake and proton conductivity than the biphenol-based (BPSH-xx) poly(arylene ether sulfone)s copolymers.

AB Titanium-aluminide intermetallic alloys and compounds are traditionally investigated and used as structural materials in high temperature applications. Here we show a novel field where microporous titanium-aluminide membrane with about 20 mu m thickness was prepared by a reactive synthesis of a commercial aluminum foil coated with a titanium layer. The porous membrane with the average pore size of about 1.2 mu m formed after sintering initially at 550 degrees C for 4 h and finally at 1300 degrees C for 30 min, showing a single phase of gamma-TiAl. The pore evolution during the synthesis procedure was investigated and analyzed through scanning electron microscopy. The pore formation mechanism is believed to be the Kirkendall effect according to a Ti/Al diffusion couple experiment (C) 2008 Published by Elsevier B.V.

TI Competition between the pseudogap and superconductivity in the high-T-c

AB In a classical Bardeen - Cooper - Schrieffer superconductor, pairing and coherence of electrons are established simultaneously below the critical transition temperature ( T-c), giving rise to a gap in the electronic energy spectrum. In the high- T-c copper oxide superconductors, however, a pseudogap(1-8) extends above T-c. The relationship between the pseudogap and superconductivity is one of the central issues in this field(9-17). Spectral gaps arising from pairing precursors are qualitatively similar to those caused by competing electronic states, rendering a standard approach to their analysis inconclusive(10-16). The issue can be settled, however, by studying the correlation between the weights associated with the pseudogap and superconductivity spectral features. Here we report a study of two spectral weights using angle- resolved photo-emission spectroscopy. The weight of the superconducting coherent peak increases away from the node following the trend of the superconducting gap, but starts to decrease in the antinodal region. This striking non- monotonicity reveals the presence of a competing state. We emonstrate a direct correlation, for different values of momenta and doping, between the loss in the low- energy spectral weight arising from the opening of the pseudogap and a decrease in the spectral weight associated with superconductivity. We therefore conclude that the pseudogap competes with the superconductivity by depleting the spectral weight available for pairing.

TI Genome Analysis of the Anaerobic Thermohalophilic Bacterium
Halothermothrix orenii
SO PLOS ONE
LA English
DT Article
AB Halothermothirx orenii is a strictly anaerobic thermohalophilic bacterium isolated from sediment of a Tunisian salt lake. It belongs to the order Halanaerobiales in the phylum Firmicutes. The complete sequence revealed that the genome consists of one circular chromosome of 2578146 bps encoding 2451 predicted genes. This is the first genome sequence of an organism belonging to the Haloanaerobiales. Features of both Gram positive and Gram negative bacteria were identified with the presence of both a sporulating mechanism typical of Firmicutes and a characteristic Gram negative lipopolysaccharide being the most prominent. Protein sequence analyses and metabolic reconstruction reveal a unique combination of strategies for thermophilic and halophilic adaptation. H. orenii can serve as a model organism for the study of the evolution of the Gram negative phenotype as well as the adaptation under thermohalophilic conditions and the development of biotechnological applications under conditions that require high temperatures and high salt concentrations.

AB The thermal reaction of vinyl chloride on nearly-stoichiometric alpha-Cr2O3 (10 (1) over bar2) produces gas phase acetylene, ethylene, 1,3-butadiene, and dihydrogen, and results in the deposition of chlorine adatoms. No surface carbon or combustion products (CO, CO2, H2O) are observed. Thermal desorption and spectroscopic studies indicate that the surface reaction of vinyl chloride proceeds through C-Cl bond cleavage to form Cl adatoms and surface vinyl groups which dehydrogenate to acetylene, hydrogenate to ethylene, and couple to form butadiene.
Cl adatoms affect surface reactivity in two ways: (1) by increasing the barrier to vinyl dehydrogenation from 145 to 160 kJ/mol, and (2) by blocking Cr3+ Sites which shuts down the surface chemistry. Selectivity to butadiene is dependent on Cl adatom coverage, where the increased stability of vinyl intermediates at lower Cl coverages gives rise to more butadiene coupling product. At higher Cl coverages, Cl appears to inhibit the mobility of surface vinyl and decreases the reaction probability for coupling.
Photoemission and near edge X-ray absorption fine structure (NEXAFS) spectra show that a mixed monolayer of molecular and dissociated vinyl chloride is formed at 130 K. The polarization dependence of the NEXAFS indicates that vinyl chloride pi-bonds with the molecular plane nominally parallel to the surface, while vinyl intermediates sigma-bond at Cr centers with the molecular plane nominally perpendicular to the surface, in agreement with DFT predictions of the adsorption geometries.

AB The interface and electronic structure of thin (similar to 20-74 nm) Co3O4(110) epitaxial films grown by oxygen-assisted molecular beam epitaxy on MgAl2O4(110) single crystal substrates have been investigated by means of real and reciprocal space techniques. As-grown film surfaces are found to be relatively disordered and exhibit an oblique low energy electron diffraction (LEED) pattern associated with the O-rich CoO2 bulk termination of the (110) surface. Interface and bulk film structure are found to improve significantly with post-growth annealing at 820 K in air and display sharp rectangular LEED patterns, suggesting a surface stoichiometry of the alternative Co2O2 bulk termination of the (110) surface. Non-contact atomic force microscopy demonstrates the presence of wide terraces separated by atomic steps in the annealed films that are not present in the as-grown structures; the step height of approximate to 2.7 angstrom corresponds to two atomic layers and confirms a single termination for the annealed films, consistent with the LEED results. A model of the (1 x 1) surfaces that allows for compensation of the polar surfaces is presented. (C) 2008 Elsevier B.V. All rights reserved.

AB Understanding the integrity of well-bore systems that are lined with Portland-based cements is critical to the successful storage of sequestered CO2 in gas and oil reservoirs. As a first step, we investigate reaction rates and mechanistic pathways for cement mineral growth in the absence of CO2 by coupling water chemistry with XRD and NMR spectroscopic data. We find that semi-crystalline calcium (alumino-)silicate hydrate (Al-CSH) forms as a precursor solid to the cement mineral tobermorite. Rate constants for tobermorite growth were found to be k = 0.6 (+/- 0.1) x 10(-5) s(-1) for a solution: solid of 10:1 and 1.6 (+/- 0.8) x 10(-4) s-1 for a solution: solid of 5: 1 (batch mode; T = 150 degrees C). This data indicates that reaction rates for tobermorite growth are faster when the solution volume is reduced by half, suggesting that rates are dependent on solution saturation and that the Gibbs free energy is the reaction driver. However, calculated solution saturation indexes for Al-CSH and tobermorite differ by less than one log unit, which is within the measured uncertainty. Based on this data, we consider both heterogeneous nucleation as the thermodynamic driver and internal restructuring as possible mechanistic pathways for growth. We also use NMR spectroscopy to characterize the site symmetry and bonding environment of Al and Si in a reacted tobermorite sample. We find two [4] Al coordination structures at (iso) = 59.9 ppm and 66.3 ppm with quadrupolar product parameters (P-Q) of 0.21 MHz and 0.10 MHz (+/- 0.08) from Al-27 3Q-MAS NMR and speculate on the Al occupancy of framework sites by probing the protonation environment of Al metal centers using Al-27{H-1} CP-MAS NMR.

AB Rotational relaxation functions of the end-to-end vector of short, freely jointed and freely rotating chains were determined from molecular dynamics simulations. The associated response functions were obtained from the one-sided Fourier transform of the relaxation functions. The Cole-Davidson function was used to fit the response functions with extensive use being made of Cole-Cole plots in the fitting procedure. For the systems studied, the Cole-Davidson function provided remarkably accurate fits [as compared to the transform of the Kohlrausch-Williams-Watts (KWW) function]. The only appreciable deviations from the simulation results were in the high frequency limit and were due to ballistic or free rotation effects. The accuracy of the Cole-Davidson function appears to be the result of the transition in the time domain from stretched exponential behavior at intermediate time to single exponential behavior at long time. Such a transition can be explained in terms of a distribution of relaxation times with a well-defined longest relaxation time. Since the Cole-Davidson distribution has a sharp cutoff in relaxation time (while the KWW function does not), it makes sense that the Cole-Davidson would provide a better frequency-domain description of the associated response function than the KWW function does.

AB We conduct classical molecular dynamics simulations to investigate isobaric melting of defective Cu solids with only one type of defect: intrinsic or extrinsic stacking faults. We characterize bulk melting and nucleation of melt in terms of order parameters, liquid cluster analysis, and the mean-first-passage-time method. The stacking faults induce negligible reduction in the temperature at melting, and the amount of superheating in these defective solids is the same as the perfect solids. Both homogeneous and heterogeneous nucleations of melt are observed. The existence of the stacking faults only slightly increases the nucleation rate and the probability of nucleation at heterogeneous nucleation sites. Such observations can be attributed to the low energy of the stacking faults and the extremely high heating rates in molecular dynamics simulations. These results underscore the necessity of considering the effects of rate and defect when interpreting experimental and simulation results as regards, e.g., phase boundaries.

AB Incoherent inelastic neutron scattering is used to probe the effects of dihydrogen bonding on the vibrational dynamics in the molecular crystal of ammonia borane. The thermal neutron energy loss spectra of (11)B enriched ammonia borane isotopomers ((11)BH(3)NH(3), (11)BD(3)NH(3), and (11)BH(3)ND(3)) are presented and compared to the vibrational power spectrum calculated using ab initio molecular dynamics. A harmonic vibrational analysis on NH(3)BH(3) clusters was also explored to check for consistency with experiment and the power spectrum. The measured neutron spectra and computed ab initio power spectrum compare extremely well (50-500 cm(-1)). Some assignment of modes to simple harmonic motion, e.g., NH(3) and BH(3) torsion in the molecular crystal is possible, and it is confirmed that the lowest modes are dominated by collective motion. We show that the vibrational dynamics as modeled with ab initio molecular dynamics provides a more complete description of anharmonic and collective dynamics in the low frequency region of the inelastic incoherent neutron scattering spectra when compared to the conventional harmonic approach.

AB Aging may be determined by a genetic program and/or by the accumulation rate of molecular damages. Reactive oxygen species (ROS) generated by the mitochondrial metabolism have been postulated to be the central source of molecular damages and imbalance between levels of intracellular ROS and antioxidant defenses is a characteristic of the aging brain. How aging modifies free radicals concentrations and increases the risk to develop most neurodegenerative diseases is poorly understood, however. Here we show that the Polycomb group and oncogene Bmi1 is required in neurons to suppress apoptosis and the induction of a premature aging-like program characterized by reduced antioxidant defenses. Before weaning, Bmi1(-/-) mice display a progeroid-like ocular and brain phenotype, while Bmi1(-/-) mice, although apparently normal, have reduced lifespan. Bmi1 deficiency in neurons results in increased p19(Arf)/p53 levels, abnormally high ROS concentrations, and hypersensitivity to neurotoxic agents. Most Bmi1 functions on neurons' oxidative metabolism are genetically linked to repression of p53 pro-oxidant activity, which also operates in physiological conditions. In Bmi1(-/-) neurons, p53 and corepressors accumulate at antioxidant gene promoters, correlating with a repressed chromatin state and antioxidant gene downregulation. These findings provide a molecular mechanism explaining how Bmi1 regulates free radical concentrations and reveal the biological impact of Bmi1 deficiency on neuronal survival and aging.

AB How to predict and better understand the effective properties of disordered material mixtures has been a long-standing problem in different research fields, especially in condensed matter physics. In order to address this subject and achieve a better understanding of the frequency-dependent properties of these systems, a large 2D L x L square structure of resistors and capacitors was used to calculate the immittance response of a network formed by random filling of binary conductor/insulator phases with 1000 Omega resistors and 10 nF capacitors. The effects of percolating clusters on the immittance response were studied statistically through the generation of 10 000 different random network samples at the percolation threshold. The scattering of the imaginary part of the immittance near the dc limit shows a clear separation between the responses of percolating and non-percolating samples, with the gap between their distributions dependent on both network size and applied frequency. These results could be used to monitor connectivity in composite materials. The effects of the content and structure of the percolating path on the nature of the observed dispersion were investigated, with special attention paid to the geometrical fractal concept of the backbone and its influence on the behavior of relaxation-time distributions. For three different resistor-capacitor proportions, the appropriateness of many fitting models was investigated for modeling and analyzing individual resistor-capacitor network dispersed frequency responses using complex-nonlinear-leastsquares fitting. Several remarkable new features were identified, including a useful duality relationship and the need for composite fitting models rather than either a simple power law or a single Davidson-Cole one. Good fits of data for fully percolating random networks required two dispersive fitting models in parallel or series, with a cutoff at short times of the distribution of relaxation times of one of them. In addition, such fits surprisingly led to cutoff parameters, including a primitive relaxation or crossover time, with estimated values comparable to those found for real dispersive materials.

AB The physics of interacting quantum wires has attracted a lot of attention recently. When the density of electrons in the wire is very low, the strong repulsion between electrons leads to the formation of a Wigner crystal. We review the rich spin and orbital properties of the Wigner crystal, in both the one-dimensional and the quasi-one-dimensional regimes. In the one-dimensional Wigner crystal the electron spins form an antiferromagnetic Heisenberg chain with exponentially small exchange coupling. In the presence of leads, the resulting inhomogeneity of the electron density causes a violation of spin-charge separation. As a consequence the spin degrees of freedom affect the conductance of the wire. Upon increasing the electron density, the Wigner crystal starts deviating from the strictly one-dimensional geometry, forming a zigzag structure instead. Spin interactions in this regime are dominated by ring exchanges, and the phase diagram of the resulting zigzag spin chain has a number of unpolarized phases as well as regions of complete and partial spin polarization. Finally we address the orbital properties in the vicinity of the transition from a one-dimensional to a quasi-one-dimensional state. Due to the locking between chains in the zigzag Wigner crystal, only one gapless mode exists. Manifestations of Wigner crystal physics at weak interactions are explored by studying the fate of the additional gapped low-energy mode as a function of interaction strength.

AB The strongly anisotropic thioarsenates A(3)Ta(2)AsS(11) are stabilized in a polysulfide flux. All compounds contain the same parallel (1)/-[Ta2AsS113-] polymeric anionic chains, but the size of the alkali-metals has a profound effect on the packing of the chains. The K+ or Rb+ favor noncentrosymmetric packing of the chains, whereas the larger Cs+ favors the centrosymmetric packing. The chains feature the combination of two asymmetric units [Ta2S11] and [AsS3] and exhibit strong nonlinear optical (NLO) second harmonic generation.

We use ratios of the Rayleigh and Raman scattering response and rotational diffusion timescales of individual nanoparticles to show that hollow gold nanospheres and solid silver nanoparticle dimers linked with a bifunctional ligand, both specifically designed nanostructures, exhibit significantly higher monodispersity than randomly aggregated gold and silver nanoparticles.

TI The Second Step of the Nitric Oxide Synthase Reaction: Evidence for
Ferric-Peroxo as the Active Oxidant

AB Nitric oxide synthase (NOS) is a P450 mono-oxygenase that catalyzes the oxidation Of L-arginine to citrulline and NO through the stable intermediate N(G)-hydroxy-L-arginine (NHA). The oxidation of NHA by NOS is unique. There is little direct evidence in support of the nature of the heme bound oxidant [i.e., ferric-peroxo vs Fe(IV)=O(por(center dot+))] responsible for this transformation. Previous work characterizing the H(2)O(2)-driven oxidation of NHA by NOS showed the formation of citrulline and the side product N(delta)-cyanoornithine (CN-orn). This led to the proposed involvement of a ferric-peroxo, intermediate in the oxidation of NHA to citrulline. To test this hypothesis we used this model reaction to study the effects of pH, heme substitution, active site mutagenesis, and a fluorinated substrate analogue on the product distribution. Further, the oxidation of 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) by H(2)O(2) and iNOS(heme) was used to probe the protein-catalyzed breakdown of peroxide to the Fe(IV)=O(por(center dot+)) intermediate. At pH 6.5, 7.5, and 8.5 the peroxide shunt reaction forms 26 +/- 2, 36 +/- 1, and 51 +/- 1% citrulline, respectively. The rate of peroxidase activity, however, was negatively correlated to pH, with a peroxide breakdown rate of 13.1 +/- 0.3, 8.3 +/- 0.2, and 4.2 +/- 0.1 M(-1) s(-1) at pH 6.5, 7.5, and 8.5, respectively. Mutation of active site valine 346 to an alanine shifted the product distribution to 5.2 +/- 0.5% citrulline while enhancing the peroxide cleavage rate to 14.3 +/- 0.7 M(-1) s(-1). Substitution of the heme cofactor with iron mesoporphyrin IX (Fe-MPIX) alters the product distribution from 36 +/- 1% citrulline to 22 +/- 3% citrulline. Metal substitution with Mn results in the formation of 64.7 +/- 0.8% citrulline. Conversely, the electrophilic 4,4-difluoro-N(G)-hydroxy-L-arginine substrate analogue shifted the product distribution to 68.6 +/- 0.6% 4,4-difluorocitrulline. The peroxidase data provide insight into the chemical features of NOS that control the processing of the ferricperoxo species to the Fe(IV)=O(por(center dot+)) intermediate and help interpret the product distributions observed for the peroxide shunt under various conditions. In all cases, the ability of the protein to break down peroxide is negatively correlated with the formation of citrulline by the peroxide shunt. These results support the high valent Fe(IV)=O(por(center dot+)) intermediate as the species responsible for CN-orn formation and are consistent with the involvement of the ferric-peroxo intermediate in the oxidation of NHA to citrulline.

AB The Ras-specific nucleotide exchange factor Son of sevenless (Sos) is inactive without Ras bound to a distal allosteric site. In contrast, the catalytic domain of Ras guanine nucleotide releasing factor 1 (RasGRF1) is active intrinsically. By substituting residues from RasGRF1 into Sos, we have generated mutants of Sos with basal activity, partially relieved of their dependence on allosteric activation. We have performed molecular dynamics simulations showing how Ras binding to the allosteric site leads to a bias toward the active conformation of Sos. The trajectories show that Sos fluctuates between active and inactive conformations in the absence of Ras and that the activating mutations favor conformations of Sos that are more permissive to Ras binding at the catalytic site. In contrast, unliganded RasGRF1 fluctuates primarily among active conformations. Our results support the premise that the catalytic domain of Sos has evolved an allosteric activation mechanism that extends beyond the simple process of membrane recruitment.

AB MAP2Ks are dual-specificity protein kinases functioning at the center of three-tiered MAP kinase modules. The structure of the kinase domain of the MAP2K MEK6 with phosphorylation site mimetic aspartic acid mutations (MEK6/Delta N/DD) has been solved at 2.3 angstrom resolution. The structure reveals an autoinhibited elongated ellipsoidal dimer. The enzyme adopts an inactive conformation, based upon structural queues, despite the phosphomimetic mutations. Gel filtration and small-angle X-ray scattering analysis confirm that the crystal lographically observed ellipsoidal dimer is a feature of MEK6/Delta N/DD and full-length unphosphorylated wild-type MEK6 in solution. The interface includes the phosphate binding ribbon of each subunit, part of the activation loop, and a rare "arginine stack" between symmetry-related arginine residues in the N-terminal lobe. The autoinhibited structure likely confers specificity on active MAP2Ks. The dimer may also serve the function in unphosphorylated MEK6 of preventing activation loop phosphorylation by inappropriate kinases.

AB DFsc is a single chain de novo designed four-helix bundle peptide that mimics the core protein fold and primary ligand set of various binuclear non-heme iron enzymes. DFsc and the E11D, Y51L, and Y18F single amino acid variants have been studied using a combination of near-IR circular dichroism (CD), magnetic circular dichroism (MCD), variable temperature variable field MCD (VTVH MCD), and X-ray absorption (XAS) spectroscopies. The biferrous sites are all weakly antiferromagnetically coupled with mu-1,3 carboxylate bridges and one 4-coordinate and one 5-coordinate Fe, very similar to the active site of class I ribonucleotide reductase (R2) providing open coordination positions on both irons for dioxygen to bridge, From perturbations of the MCD and VTVH MCD the iron proximal to Y51 call be assigned as the 4-coordinate center, and XAS results show that Y51 is not bound to this iron in the reduced state. The two open coordination positions on one iron in the biferrous state would become occupied by dioxygen and Y51 along the 02 reaction coordinate. Subsequent binding of Y51 functions as an internal spectral probe of the 02 reaction and as a proton source that Would promote loss of H2O2. Coordination by a ligand that functions as a proton Source could be a structural mechanism used by natural binuclear iron enzymes to drive their reactions past peroxo biferric level intermediates.

AB Silicone nanospheres containing a variety of functional groups (pyridines, phosphines, thiols, amines, etc.) have been prepared by emulsion copolymerization of methyltrimethoxysilane, MeSi(OMe)(3), and the functionalized monomer of interest, RSi(OMe)(3). This procedure provides a reproducible synthesis of spherical particles in the 12-28 nm size regime as determined by transmission electron microscopy (TEM). The presence of the functional groups is supported by a combination of spectroscopic methods including DRUV-vis, DRIFTS, and NMR spectroscopy. Comonomer dispersity within the nanospheres was probed using elemental mapping techniques, and these support a homogeneous distribution of functional groups within the particles. Palladium(0) immobilization on phosphine-substituted nanospheres also results in a random distribution of the transition metal throughout the particles. Nanospheres containing multiple acid/base functionalities were also prepared, and these demonstrate functional group cooperativity based on enhanced conversions in the base-catalyzed Henry reaction, relative to nanosphere catalysts containing only basic groups. The diversity of functional groups that may be incorporated into the spheres suggests that these materials hold considerable promise as ligand supports and catalysts.

AB A significant challenge in contaminant transport modeling is to obtain a mechanistic understanding of transport parameter scaling that accurately addresses the combined influence of physical and chemical heterogeneities at different scales. In this paper, we have developed a scaling methodology to upscale matrix sorption coefficients for fractured- rock systems by characterizing both the tortuosity field (physical heterogeneity) and retardation factor field (chemical heterogeneity) in the rock matrix. We compute the effective tortuosity with a conservative tracer (e.g., tritium), and then using a sorbing tracer (e.g., uranium), we derive the equations for upscaling the sorption coefficients in a saturated, fractured rock system. The derived upscaling equations for the sorption coefficients are verified with Monte Carlo simulations, which are based on a generalized dual-porosity model to enable highly efficient and accurate numerical simulations of diffusive concentration fronts moving between the fractures and matrix material. The scientific results from this study will provide a theoretical and practical link between controlled experimental results at scales increasing from the laboratory bench to the field scale at which risk assessment and contaminant remediation are actually conducted.

AB We use lightning sferics from the World Wide Lightning Location Network to identify storms near 362 Terrestrial Gamma-ray Flashes (TGFs). The combined spectrum of TGFs with storms within 300 km of the sub-satellite point is much harder than the spectrum of TGFs with more distant storms. When these data are compared with simulations of vertically oriented relativistic runaway breakdown, it is found that the most likely model has a source altitude of 15 km and a wide-beam geometry. We find four associations of TGFs with individual sferics geolocated to positions more than 300 km from the sub-satellite point and show that a narrow-beam source at >= 21 km altitude is unlikely to produce the number of high energy photons in these TGFs.

AB Diblock copolymers having a random-coil polymer block (polystyrene, PS) connected to a side-group liquid crystal polymer (SGLCP) self-assemble in a nematic liquid crystal (LC), 4-pentyl-4'-cyanobiphenyl, into micelles with PS-rich cores and SGLCP-rich coronas. The morphologies of block copolymers with varying PS content are characterized as a function of temperature and concentration using small-angle neutron scattering, rheometry. and transmission electron microscopy. Unlike conventional solvents, the nematic LC can undergo a first-order transition between distinct fluid phases, accessing the regimes of both strong and slight selectivity in a single polymer/solvent pair. Micelles dissolve away above a microphase separation temperature (MST) that is often equal to the solution's isotropization point. T(NI). However. increasing or decreasing the polymer's PS content can shift the MST to be above or below T(NI). respectively. and in the former case, micelles abruptly swell with solvent at T(NI). Comparable effects can be achieved by modulating the overall polymer concentration.

AB Ebola viruses (EBOVs) cause rare but highly fatal outbreaks of viral hemorrhagic fever in humans, and approved treatments for these infections are currently lacking. The Ebola VP35 protein is multifunctional, acting as a component of the viral RNA polymerase complex, a viral assembly factor, and an inhibitor of host interferon (IFN) production. Mutation of select basic residues within the C-terminal half of VP35 abrogates its dsRNA-binding activity, impairs VP35-mediated IFN antagonism, and attenuates EBOV growth in vitro and in vivo. Because VP35 contributes to viral escape from host innate immunity and is required for EBOV virulence, understanding the structural basis for VP35 dsRNA binding, which correlates with suppression of IFN activity, is of high importance. Here, we report the structure of the C-terminal VP35 IFN inhibitory domain (IID) solved to a resolution of 1.4 angstrom and show that VP35 IID forms a unique fold. In the structure, we identify 2 basic residue clusters, one of which is important for dsRNA binding. The dsRNA binding cluster is centered on Arg-312, a highly conserved residue required for IFN inhibition. Mutation of residues within this cluster significantly changes the surface electrostatic potential and diminishes dsRNA binding activity. The high-resolution structure and the identification of the conserved dsRNA binding residue cluster provide opportunities for antiviral therapeutic design. Our results suggest a structure-based model for dsRNA-mediated innate immune antagonism by Ebola VP35 and other similarly constructed viral antagonists.

AB Domain orientation in polymer electrolyte membranes is tuned by controlling its sulfonation level and the moisture content of the air. At low sulfonation levels, highly ordered hydrophobic cylinders oriented perpendicular to the film surface are obtained, when the film is in humid air. Increasing the sulfonation level results in a transition from perpendicular to parallel orientation.

AB Epithelial cells, once dissociated and placed in two-dimensional (2D) cultures, rapidly lose tissue-specific functions. We showed previously that in addition to prolactin, signaling by laminin-111 was necessary to restore functional differentiation of mammary epithelia. Here, we elucidate two additional aspects of laminin-111 action. We show that in 2D cultures, the prolactin receptor is basolaterally localized and physically segregated from its apically placed ligand. Detachment of the cells exposes the receptor to ligation by prolactin leading to signal transducers and activators of transcription protein 5 (STAT5) activation, but only transiently and not sufficiently for induction of milk protein expression. We show that laminin-111 reorganizes mammary cells into polarized acini, allowing both the exposure of the prolactin receptor and sustained activation of STAT5. The use of constitutively active STAT5 constructs showed that the latter is necessary and sufficient for chromatin reorganization and beta-casein transcription. These results underscore the crucial role of continuous laminin signaling and polarized tissue architecture in maintenance of transcription factor activation, chromatin organization, and tissue-specific gene expression.

TI Structural Model of the Rev Regulatory Protein from Equine Infectious
Anemia Virus
SO PLOS ONE
LA English
DT Article
AB Rev is an essential regulatory protein in the equine infectious anemia virus (EIAV) and other lentiviruses, including HIV-1. It binds incompletely spliced viral mRNAs and shuttles them from the nucleus to the cytoplasm, a critical prerequisite for the production of viral structural proteins and genomic RNA. Despite its important role in production of infectious virus, the development of antiviral therapies directed against Rev has been hampered by the lack of an experimentally-determined structure of the full length protein. We have used a combined computational and biochemical approach to generate and evaluate a structural model of the Rev protein. The modeled EIAV Rev (ERev) structure includes a total of 6 helices, four of which form an anti-parallel four-helix bundle. The first helix contains the leucine-rich nuclear export signal (NES). An arginine-rich RNA binding motif, RRDRW, is located in a solvent-exposed loop region. An ERLE motif required for Rev activity is predicted to be buried in the core of modeled structure where it plays an essential role in stabilization of the Rev fold. This structural model is supported by existing genetic and functional data as well as by targeted mutagenesis of residues predicted to be essential for overall structural integrity. Our predicted structure should increase understanding of structure-function relationships in Rev and may provide a basis for the design of new therapies for lentiviral diseases.

AB It is important to accurately adjust the amplitude and the phase of RF power sources for a high intensity proton linac. J-PARC (Japan proton accelerator research complex) linac is one of those high-intensity linacs. J-PARC linac has 30 SDTL (separate-type drift tube linac) tanks to accelerate the negative hydrogen ions from 50 to 181 MeV. Two neighboring SDTL tanks are driven by one klystron, where the phase and the amplitude of these two tanks are controlled in terms of the vector sum. The target-value of the vector sum control should be determined with a beam-based tuning for each klystron. During the beam commissioning, the RF tuning has been performed with a phase scan method introducing a concept of phase signature matching. In the tuning, the output beam energy from the SDTL module is monitored while scanning the RF phase. Comparing the obtained phase dependence of the output beam energy with those from a numerical model, the target-values for the low-level RF control system has been tuned within the required accuracy of V in phase and 1% in amplitude. The same tuning procedure has successfully been applied to the RF tuning of buncher and debuncher cavities. Published by Elsevier B.V.

AB In the beam pipe of high-intensity positron/proton storage rings, undesired electron clouds may be first produced by photoelectrons and the ionization of residual gases; then the clouds increase by the secondary electron emission. In this study, a strip-line clearing electrode has been developed to mitigate the electron-cloud effect in high-intensity positron/proton storage rings. The electrode is composed of a thin tungsten layer with a thickness of 0.1 mm formed on a thin alumina ceramic layer with a thickness of 0.2 mm. The narrow alumina gap between the electrode and the beam pipe decreases the beam impedance and also enhances the heat transfer from the electrode to the beam pipe. A test model has been installed in the KEK B-factory (KEKB) positron ring, along with an electron monitor with a retarding grid. The electron density in a field free region decreased by one order of magnitude was observed on the application of +/- 500 V to the electrode at a beam current of 1.6 A with 1585 bunches. The reduction in the electron density was more drastic in a vertical magnetic field of 0.77 T, that is, the electron density decreased by several orders by applying +500V to the electrode at the same beam current. This experiment is the first experiment demonstrating the principle of the clearing electrode that is used to mitigate the electron-cloud effect in a positron ring. (C) 2008 Elsevier B.V.

ID DESIGN
AB An RF deflecting structure has been designed and fabricated for a transverse-to-longitudinal emittance exchange experiment at Argonne National Laboratory (ANL) [Y.-E. Sun, et al., Design study of a transverse-to-longitudinal emittance exchange proof-of-principle experiment, in: Proceedings of PAC-2007, Albuquerque, NM, USA, 2007, pp. 3441-3443 [1]]. The structure is a 1300 MHz normal conducting RF cavity consisting of three cells operating in a dipole (TM110-like) mode. As high as 3.4 MV deflecting voltage is required for the experiment. In this paper, we present detailed RF design of the cavity, particle tracking simulations in the cavity and low power RF measurement results in comparison with numerical simulations. The cavity cell geometries (gaps in particular) are optimized to giving a zero orbit offset for particles crossing the cavity with zero-phase. (C) 2008 Elsevier B.V. All rights reserved.

AB The purpose of the MIPP experiment is to study the inclusive production of photons, pions, kaons, and nucleons in pi, K, and p interactions on various targets using beams from the Main Injector at Fermilab. The function of the calorimeters is to measure the production of forward-going neutrons and photons. The electromagnetic calorimeter consists of 10 lead plates interspersed with proportional chambers. It was followed by the hadron calorimeter with 64 steel plates interspersed with scintillator. The data presented were collected with a variety of targets and beam momenta from 5 to 120 GeV/c. The energy calibration of both calorimeters with electrons, pions, kaons, and protons is discussed. The resolution for electrons was found to be 0.27/root E, and for hadrons the resolution was 0.554/root E with a constant term of 2.6%. The performance of the calorimeters was tested on a neutron sample. (C) 2008 Elsevier B.V. All rights reserved.

AB The aim of this study is the evaluation of radiation effects in detectors based on p-type magnetic czochralski (MCz) Si that was converted to n-type by thermal donor (TD) introduction. As-processed p(+)-p-n(+) detectors were annealed at 430 degrees C resulting in p(+)-n(TD)-n(+) structures. The space charge sign and the electric field distribution E(x) in MCz Si p(+)-n(TD)-n(+) detectors irradiated by 24GeV/c protons were analyzed using the data on the current pulse response and the Double Peak (DP) electric field distribution model for heavily irradiated detectors. The approach considers an irradiated detector as a structure with three regions in which the electric field depends on the coordinate, and the induced current pulse response arises from the drift process of free carriers in the detector with variable electric field. Reconstruction of the E(x) profile from the pulse response shapes is performed employing a new method for DP electric field reconstruction. This method includes: (a) a direct extraction of charge loss due to trapping and (b) the fitting of a simulated pulse response to the "corrected" pulse by adjusting the electric field profiles in the three regions. Reconstruction of E(x) distribution showed that in the diodes irradiated by a proton fluence of (2-4) x 10(14) p/cm(2) space charge sign inversion has occurred. This is the evidence that the influence of 24 GeV/c proton radiation on MCz Si p(+)-n(TD)-n(+) detectors is similar to that on p(+)-n-n(+) detectors based on FZ or diffusion oxygenated n-type Si.

DE X-ray streak camera; Longitudinal magnification
AB X-ray streak cameras (XSC) have been known to be one of the fastest detectors for ultrafast X-ray science. A number of applications in material science, biochemistry, accelerator physics, require sub-picosecond resolution to study new phenomena. In this paper, we report on a new method which can potentially improve the temporal resolution of a streak camera down to 100 fs, This method uses a time-dependent acceleration field to lengthen the photoelectron bunch, improving the time resolution as well as reducing the time dispersion caused by initial energy spread and the effects from the space charge forces. A computer simulation of an XSC using this method shows significant improvement in the resolution. (C) 2008 Elsevier B.V. All rights reserved.

AB A long-trace profiler (LTP) optimized for Measuring the shape of large neutron supermirrors has been designed and built, This LTP can measure 1.6 m long mirrors in both vertically and horizontally deflecting geometries, which is essential to achieve best performance from bendable mirrors. The LTP suppresses the influence of angular deviations of the linear-stage carriage during translation with a pentaprism and a cylindrical lens. The stationary optical head and the carriage-mounted pentaprism are precisely aligned to rotate about the Optical axis between the two components. This feature allows measurements to be made on mirrors mounted vertically, horizontally or at any angle in between. The LTP software allows for rapid optimization of parameters for dynamically bent elliptical mirrors. Here we describe the motivation for the L:FP, the design, and a first application of the LTP to study the effect of gravity on a bent microfocusing neutron supermirror. (C) 2008 Elsevier B.V.

AB Monolithic CMOS pixel sensors offer unprecedented opportunities for fast nano-imaging through direct electron detection in transmission electron microscopy. We present the design and a full characterisation of a CMOS pixel test structure able to withstand doses in excess of 1 Mrad. Data collected with electron beams at various energies of interest in electron microscopy are compared to predictions of simulation and to 1.5 GeV electron data to disentagle the effect of multiple scattering. The point spread function measured with 300 keV electrons is (8.1 +/- 1.6) pm for 10 mu m pixel and (10.9 +/- 2.3) mu m for 20 mu m pixels, respectively, which agrees well with the values of 8.4 and 10.5 mu m predicted by our simulation.

AB A compound external cavity is designed and implemented to achieve a homogeneous spectrum distribution of broad area laser diodes in an array and to narrow the spectral linewidth of the entire array. The compound external cavity is composed of an optical coupler and a Littrow external cavity with a telescope along the fast axis. The inhomogeneous distribution of individual laser diodes spectrum generated by the "smile" effect was reduced by the telescope. The effective transverse coupling among individual laser diodes in an array was enhanced by the optical coupler, which further reduced the spectrum inhomogeneous distribution of the entire array. The spectral linewidth of a 49-emitter laser array is reduced to 0.1nm at the output power of 12.5W. (c) 2009 Optical Society of America

GIANTS
AB Type I planetary nebulae (PNe) have high He/H and N/O ratios and are thought to be descendants of stars with initial masses of similar to 3-8 M-circle dot. These characteristics indicate that the progenitor stars experienced proton-capture nucleosynthesis at the base of the convective envelope, in addition to the slow neutron capture process operating in the He-shell (the s-process). We compare the predicted abundances of elements up to Sr from models of intermediate-mass asymptotic giant branch (AGB) stars to measured abundances in Type I PNe. In particular, we compare predictions and observations for the light trans-iron elements Se and Kr, in order to constrain convective mixing and the s-process in these stars. A partial mixing zone is included in selected models to explore the effect of a C-13 pocket on the s-process yields. The solar-metallicity models produce enrichments of [(Se, Kr)/Fe] less than or similar to 0.6, consistent with Galactic Type I PNe where the observed enhancements are typically less than or similar to 0.3 dex, while lower metallicity models predict larger enrichments of C, N, Se, and Kr. O destruction occurs in the most massive models but it is not efficient enough to account for the less than or similar to 0.3 dex O depletions observed in some Type I PNe. It is not possible to reach firm conclusions regarding the neutron source operating in massive AGB stars from Se and Kr abundances in Type I PNe; abundances for more s-process elements may help to distinguish between the two neutron sources. We predict that only the most massive (M greater than or similar to 5 M-circle dot) models would evolve into Type I PNe, indicating that extra-mixing processes are active in lower-mass stars (3-4 M-circle dot), if these stars are to evolve into Type I PNe.

AB We study the formation of 53 galaxy cluster-size dark matter halos (M = 10(14.0-14.76) M(circle dot)) formed within a pair of cosmological. cold dark matter N-body simulations, and track the accretion histories of cluster subhalos with masses large enough to host similar to 0.3 L(*) galaxies. By associating subhalos with cluster galaxies, we find the majority of galaxies in clusters experience no "preprocessing" in the group environment prior to their accretion into the cluster. On average, 70% of cluster galaxies fall into the cluster potential directly from the field, with no luminous companions in their host halos at the time of accretion; less than 12% are accreted as members of groups with five or more galaxies. Moreover, we find that cluster galaxies are significantly less likely to have experienced amerger in the recent past (similar to 6Gyr) than a field halo of the same mass. These results suggest that local cluster processes such as ram pressure stripping, galaxy harassment, or strangulation play the dominant role in explaining the difference between cluster and field populations at a fixed stellar mass, and that pre-evolution or past merging in the group environment is of secondary importance for setting cluster galaxy properties for most clusters. The accretion times for z = 0 cluster members are quite extended, with similar to 20% incorporated into the cluster halo more than 7 Gyr go and similar to 20% within the last 2 Gyr. By comparing the observed morphological fractions in cluster and field populations, we estimate an approximate timescale for late-type to early-type transformation within the cluster environment to be similar to 6 Gyr.

AB We present observations of SCP 06F6, an unusual optical transient discovered during the Hubble Space Telescope Cluster Supernova Survey. The transient brightened over a period of similar to 100 days, reached a peak magnitude of similar to 21.0 in both i(775) and z(850), and then declined over a similar timescale. There is no host galaxy or progenitor star detected at the location of the transient to a 3 sigma upper limit of i(775) >= 26.4 and z(850) >= 26.1, giving a corresponding lower limit on the flux increase of a factor of similar to 120. Multiple spectra show five broad absorption bands between 4100 angstrom and 6500 angstrom, and a mostly featureless continuum longward of 6500 angstrom. The shape of the light curve is inconsistent with microlensing. The transient's spectrum, in addition to being inconsistent with all known supernova types, does not match any spectrum in the Sloan Digital Sky Survey database. We suggest that the transient may be one of a new class.

AB The high-frequency-peaked BL Lacertae object 1ES 0806+524, at redshift z = 0.138, was observed in the very high energy (VHE) gamma-ray regime by VERITAS between 2006 November and 2008 April. These data encompass the two- and three-telescope commissioning phases, as well as observations with the full four-telescope array. 1ES 0806+524 is detected with a statistical significance of 6.3 standard deviations from 245 excess events. Little or no measurable variability on monthly timescales is found. The photon spectrum for the period 2007 November to 2008 April can be characterized by a power law with photon index 3.6 +/- 1.0(stat) +/- 0.3(sys) between similar to 300 GeV and similar to 700 GeV. The integral flux above 300 GeV is ( 2.2 +/- 0.5(stat) +/- 0.4(sys)) x 10(-12)cm(-2)s(-1) which corresponds to 1.8% of the Crab Nebula flux. Non-contemporaneous multiwavelength observations are combined with the VHE data to produce a broadband spectral energy distribution that can be reasonably described using a synchrotron-self-Compton model.

AB We discuss implications of recent precision measurements for the (93)Rh proton separation energy for the production of the lightest molybdenum isotopes in proton-rich Type II supernova (SN II) ejecta. It has recently been shown that a novel neutrino-induced process makes these ejecta a promising site for the production of the light molybdenum isotopes and other " p-nuclei" with atomic mass near 100. The origin of these isotopes has long been uncertain. A distinguishing feature of nucleosynthesis in neutrino-irradiated outflows is that the relative production of (92)Mo and (94)Mo is set by a competition governed by the proton separation energy of (93)Rh. We use the detailed nuclear network calculations and the recent experimental results for this proton separation energy to place constraints on the outflow characteristics that produce the lightest molybdenum isotopes in their solar proportions. It is found that for the conditions calculated in recent two-dimensional SN simulations, and also for a large range of outflow characteristics around these conditions, the solar ratio of (92)Mo to (94)Mo cannot be achieved. This suggests that either proton-rich winds from SNe II do not exclusively produce both isotopes, or that these winds are qualitatively different than calculated in today's SN models.

AB The High Energy Stereoscopic System (HESS) survey of the Galactic plane has established the existence of a substantial number (similar to 40) of Galactic TeV gamma-ray sources, a large fraction of which remain unidentified. HESS J0632+057 is one of a small fraction of these objects, which is point-like in nature (< 2' rms), and is one of only two point-like sources that remain unidentified. Follow-up observations of this object with XMM-Newton have revealed an X-ray source coincident with the TeV source and with the massive star MWC 148, of the spectral type B0pe. This source exhibits a hard spectrum, consistent with an absorbed power law with Gamma = 1.26 +/- 0.04, and shows significant variability on hour timescales. We discuss this spatial coincidence and the implied spectral energy distribution of this object and argue that it is likely a new gamma-ray binary system with a close resemblance to the three known members of this class and, in particular, to LS I+61 303. Further, X-ray, radio, and optical observations of this system are needed to firmly establish HESS J0632+057 as a new member of this rare class of Galactic objects.

ID SPACE
AB The accurate modeling of wind turbines is an extremely challenging problem due to the tremendous complexity of the machines and the turbulent and unpredictable conditions in which they operate. Adaptive control techniques are well Suited to nonlinear applications, Such as wind turbines, which are difficult to accurately model and which have effects from poorly known operating environments. In this paper, we extended the direct model reference adaptive control (DMRAC) approach to track a reference point and to reject persistent disturbances. This approach was then used to design an adaptive collective pitch controller for a high-fidelity simulation of a variable-speed horizontal axis wind turbine. The objective of the adaptive pitch controller was to regulate generator speed in Region 3 and to reject step disturbances. The control objective was accomplished by collectively pitching the turbine blades.
The turbine simulation models the controls advanced research turbine (CART) of the National Renewable Energy Laboratory in Golden, Colorado. The CART is a utility-scale wind turbine that has a well-developed and extensively verified simulator. This novel application of adaptive control was compared in simulations with a classical proportional integrator (PI) collective pitch controller. In the simulations, the adaptive pitch controller showed improved speed regulation in Region 3 when compared with the PI pitch controller. Copyright (C) 2008 John Wiley & Sons, Ltd.

AB Condensins are key mediators of chromosome condensation across organisms. Like other condensins, the bacterial MukBEF condensin complex consists of an SMC family protein dimer containing two ATPase head domains, MukB, and two interacting subunits, MukE and MukF. We report complete structural views of the intersubunit interactions of this condensin along with ensuing studies that reveal a role for the ATPase activity of MukB. MukE and MukF together form an elongated dimeric frame, and MukF's C-terminal winged-helix domains (C-WHDs) bind MukB heads to constitute closed ring-like structures. Surprisingly, one of the two bound C-WHDs is forced to detach upon ATP-mediated engagement of MukB heads. This detachment reaction depends on the linker segment preceding the C-WHD, and mutations on the linker restrict cell growth. Thus ATP-dependent transient disruption of the MukB-MukF interaction, which creates openings in condensin ring structures, is likely to be a critical feature of the functional mechanism of condensins.

AB Segregation of nonexchange chromosomes during Drosophila melanogaster meiosis requires the proper function of NOD, a nonmotile kinesin-10. We have determined the X-ray crystal structure of the NOD catalytic domain in the ADP- and AMPPNP-bound states. These structures reveal an alternate conformation of the microtubule binding region as well as a nucleotide-sensitive relay of hydrogen bonds at the active site. Additionally, a cryo-electron microscopy reconstruction of the nucleotide-free microtubule-NOD complex shows an atypical binding orientation. Thermodynamic studies show that NOD binds tightly to microtubules in the nucleotide-free state, yet other nucleotide states, including AMPPNP, are weakened. Our pre-steady-state kinetic analysis demonstrates that NOD interaction with microtubules occurs slowly with weak activation of ADP product release. Upon rapid substrate binding, NOD detaches from the microtubule prior to the rate-limiting step of ATP hydrolysis, which is also atypical for a kinesin. We propose a model for NOD's microtubule plus-end tracking that drives chromosome movement.

TI Functionally Distinct NEAT (NEAr Transporter) Domains within the
Staphylococcus aureus IsdH/HarA Protein Extract Heme from Methemoglobin

AB The pathogen Staphylococcus aureus uses iron-regulated surface determinant (Isd) proteins to scavenge the essential nutrient iron from host hemoproteins. The IsdH protein (also known as HarA) is a receptor for hemoglobin (Hb), haptoglobin (Hp), and the Hb-Hp complex. It contains three NEAT (NEAr Transporter) domains: IsdHN1, IsdHN2, and IsdHN3. Here we show that they have different functions; IsdHN1 binds Hb and Hp, whereas IsdHN3 captures heme that is released from Hb. The staphylococcal IsdB protein also functions as an Hb receptor. Primary sequence homology to IsdH indicates that it will also employ functionally distinct NEAT domains to bind heme and Hb. We have used site-directed mutagenesis and surface plasmon resonance methods to localize the Hp and Hb binding surface on IsdHN1. High affinity binding to these structurally unrelated proteins requires residues located within a conserved aromatic motif that is positioned at the end of the beta-barrel structure. Interestingly, this site is quite malleable, as other NEAT domains use it to bind heme. We also demonstrate that the IsdC NEAT domain can capture heme directly from Hb, suggesting that there are multiple pathways for heme transfer across the cell wall.

POLARIZED REFLECTANCE; SATELLITE RETRIEVAL; MULTIPLE-SCATTERING; SIZE

AB We present a new approach to retrieve the aerosol properties over land that uses accurate polarization measurements over a broad spectral (410-2250 nm) and angular (+/- 60 degrees from nadir) ranges. The approach uses longer wavelength observations to accurately estimate the surface effects, and it is incorporated into an optimal estimation framework for retrieving the particle number density and a detailed aerosol microphysical model: effective radius, variance, and complex refractive index. A sensitivity analysis shows that the uncertainties in aerosol optical thickness (AOT) increase with AOT while the uncertainties in the microphysical model decrease. The uncertainty in the single scattering albedo (SSA) is notably less than 0.05 by the time the AOT is greater than 0.2. We find that calibration is the major source of uncertainty and that perfect angular and spectral correlation of calibration errors reduces the uncertainties in retrieved quantities. Finally, we observe that shorter wavelength (< 500 nm) observations are crucial for determining the aerosols vertical extent and imaginary refractive index from polarization measurements. The retrieval approach is tested under pristine and polluted conditions using observations made by the Research Scanning Polarimeter during the Aerosol Lidar Validation experiment and over California Southern wild fires. In both cases we find that the retrievals are within the combined uncertainties of the retrieval and the Aerosol Robotic Network Cimel products and Total Ozone Mapping Spectrometer Aerosol Index. This demonstrates the unique capability of polarization measurements to accurately retrieve AOTs under pristine conditions and provide estimation of the SSA at higher AOTs.

AB The emergence of resistance to vancomycin and related glycopeptide antibiotics is spurring efforts to develop new antimicrobial therapeutics. Hgh-resolution structural information about antibiotic-ligand recognition should prove valuable in the rational design of improved drugs. We have determined the X-ray crystal structure of the complex of vancomycin with N-acetyl-D-Ala-D-Ala, a mimic of the natural muramyl peptide target, and refined this structure at a resolution of 13 angstrom to R and R(free) values of 0.172 and 0.195, respectively. The crystal asymmetric unit contains three back-back vancomycin dinners; two of these dimers participate in ligand-mediated face-face interactions that produce an infinite chain of molecules running throughout the crystal. The third dimer packs against the side of a face-face interface in a tight "side-side" interaction that involves both polar contacts and burial of hydrophobic surface. The trimer of dimers found in the asymmetric unit is essentially identical to complexes seen in three other crystal structures of glycopeptide antibiotics complexed with peptide ligands. These four structures are derived from crystals belonging to different space groups, suggesting that the trimer of dimers may not be simply a crystal packing artifact and prompting us to ask if ligand-mediated oligomerization could be observed in solution. Using size-exclusion chromatography, dynamic light scattering, and small-angle X-ray scattering, we demonstrate that vancomycin forms discrete supramolecular complexes in the presence of tripeptide ligands. Size estimates for these complexes are consistent with assemblies containing four to six vancomycin monomers. (C) 2008 Elsevier Ltd. All rights reserved.

AB We report results from the Cryogenic Dark Matter Search at the Soudan Underground Laboratory (CDMS II) featuring the full complement of 30 detectors. A blind analysis of data taken between October 2006 and July 2007 sets an upper limit on the weakly interacting massive particle (WIMP) nucleon spin-independent cross section of 6.6 x 10(-44) cm(2) (4.6 x 10(-44) cm(2) when combined with previous CDMS II data) at the 90% confidence level for a WIMP mass of 60 GeV/c(2). This achieves the best sensitivity for dark matter WIMPs with masses above 44 GeV/c(2), and significantly restricts the parameter space for some favored supersymmetric models.

AB We report e(+)e(-) -> b (b) over bar cross section measurements by the BABAR experiment performed during an energy scan in the range of 10.54 to 11.20 GeV at the SLAC PEP-II e(+)e(-) collider. A total relative error of about 5% is reached in more than 300 center-of-mass energy steps, separated by about 5 MeV. These measurements can be used to derive precise information on the parameters of the Y(10860) and Y (11020) resonances. In particular we show that their widths may be smaller than previously measured.

TI Quantum Phase Transition in the Magnetic-Field-Induced Normal State of

AB A 60 T magnetic field suppresses the superconducting transition temperature T-c in La2-pSrpCuO4 to reveal a Hall number anomaly, which develops only at temperatures below zero-field T-c and peaks at the exact location of p that maximizes T-c. The anomaly bears a striking resemblance to observations in Bi2Sr2-xLaxCuO6+delta, suggesting a normal-state phenomenology common to the cuprates that underlies the high-temperature superconducting phase. The peak is ascribed to a Fermi surface reconstruction at a quantum phase transition near optimum doping that is coincident with the collapse of the pseudogap state.

Single-Molecule Fluorescence Spectroscopy
SO PHYSICAL REVIEW LETTERS

DT Article
ID RESONANCE FLUORESCENCE; DYNAMICS
AB We derive the moment generating function for photon emissions from a single molecule driven by laser excitation. The frequencies of the fluoresced photons are explicitly considered. Calculations are performed for the case of a two-level dye molecule, showing that measured photon statistics will display a strong and nonintuitive dependence on detector bandwidth. Moreover, it is demonstrated that the antibunching phenomenon, associated with negative values of Mandel's Q parameter, results from correlations between photons with well separated frequencies.

TI Kinetic Alfven Wave Turbulence and Transport through a Reconnection
Diffusion Region
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
AB We demonstrate from observations that kinetic Alfven waves may play an important role in facilitating magnetic reconnection. These waves radiate outwards from the diffusion region oblique to the magnetic field in a conelike pattern delimited by the X line separatrices with outward energy fluxes equivalent to that contained in the outstreaming ions. It is shown that the wave vectors reverse across the X and symmetry lines and have a large out of plane component. We estimate that these waves drive significant transport through the diffusion region.

TI Direct Observation of a Nuclear Spin Excitation in Ho2Ti2O7
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID MAGNETIC-PROPERTIES; CRYSTAL-FIELD; ICE; RELAXATION; HYPERFINE; STATE
AB A single nondispersive excitation is observed by means of neutron backscattering, at E-0=26.3 mu eV in the spin ice Ho2Ti2O7 but not in the isotopically enriched (Dy2Ti2O7)-Dy-162 analogue. The intensity of this excitation is rather small, less than or similar to 0.2% of the elastic intensity. It is clearly observed below 80 K but resolution limited only below similar to 65 K. The application of a magnetic field up to mu H-0=4.5 T, at 1.6 K, has no measurable effect on the energy or intensity. This nuclear excitation is believed to perturb the electronic, Ising spin system resulting in the persistent spin dynamics observed in spin ice compounds.

AB We study the low-temperature magnetophotoluminescence from individual CdSe nanocrystals. Nanocrystals having a small "bright" exciton fine structure splitting (Delta(XY)< 0.5 meV) exhibit a conventional left and right circularly polarized Zeeman photoluminescence doublet in applied magnetic fields. In contrast, nanocrystals with large Delta(XY) (> 1 meV) show an anomalous magnetophotoluminescence polarization, wherein the lower-energy peak becomes circularly polarized with increasing field, while the higher-energy peak remains linearly polarized. This unusual behavior arises from strong mixing between the absorbing and emitting bright exciton levels due to strong anisotropic exchange interactions.

TI Intrinsic Nucleation Mechanism and Disorder Effects in Polarization
Switching on Ferroelectric Surfaces
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
AB The temperature dependence of ferroelectric domain nucleation in epitaxial films of BiFeO(3) is studied using variable temperature ultrahigh vacuum piezoresponse force spectroscopy in the 50 to 300 K temperature range. The nucleation bias corresponding to the onset of local ferroelectric switching in the volume of an electrostatic field confined by the metal tip was found to change less than 20% across the entire temperature range. A combination of the analytical and phase-field analysis proves that the weak temperature dependence of nucleation bias is a hallmark of an intrinsic nucleation mechanism with minimal contribution of thermal fluctuations. The effect of disorder on the observed distribution of the nucleation bias between vacuum and ambient environments is compared.

TI First Measurement of the Neutron beta Asymmetry with Ultracold Neutrons
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID POLARIZED NEUTRONS; GA-GV; DECAY; TESTS; PRECISION; MODEL
AB We report the first measurement of an angular correlation parameter in neutron beta decay using polarized ultracold neutrons (UCN). We utilize UCN with energies below about 200 neV, which we guide and store for similar to 30 s in a Cu decay volume. The interaction of the neutron magnetic dipole moment with a static 7 T field external to the decay volume provides a 420 neV potential energy barrier to the spin state parallel to the field, polarizing the UCN before they pass through an adiabatic fast passage spin flipper and enter a decay volume, situated within a 1 T field in a 2 x 2 pi solenoidal spectrometer. We determine a value for the beta-asymmetry parameter A(0) = -0.1138 +/- 0.0046 +/- 0.0021.

TI Origin and Enhancement of Hole-Induced Ferromagnetism in First-Row d(0)
Semiconductors
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID COLLECTIVE ELECTRON FERROMAGNETISM; ENERGY; MODEL
AB The origin of ferromagnetism in d(0) semiconductors is studied using first-principles methods with ZnO as a prototype material. We show that the presence of spontaneous magnetization in nitrides and oxides with sufficient holes is an intrinsic property of these first-row d(0) semiconductors and can be attributed to the localized nature of the 2p states of O and N. We find that acceptor doping, especially doping at the anion site, can enhance the ferromagnetism with much smaller threshold hole concentrations. The quantum confinement effect also reduces the critical hole concentration to induce ferromagnetism in ZnO nanowires. The characteristic nonmonotonic spin couplings in these systems are explained in terms of the band coupling model.

ID HARD-SPHERE MIXTURES; STRUCTURAL CROSSOVER; X-RAY; SUPERLATTICES;
NANOTECHNOLOGY; PARTICLES
AB Monolayers of bimodal gold nanoparticles on silicon are investigated by a combination of microscopy (dry monolayers) and x-ray diffraction (dry and wet monolayers). In the presence of an excess of small particles, the nanoscale packing structure closely resembles the small-particle-rich scenario of the structural crossover transition that has been predicted and also observed with micron-scale hard-sphere colloids. Structural morphology is monitored in situ during monolayer dissolution and reassembly within the thin liquid wetting film. This approach allows investigation of size and solvent effects on nanoparticles in quasi-two-dimensional confinement.

AB We present a comparative study of ultrafast photoconversion dynamics in tetracene (Tc) and pentacene (Pc) single crystals and Pc films using optical pump-probe spectroscopy. Photoinduced absorption in Tc and Pc crystals is activated and temperature-independent, respectively, demonstrating dominant singlet-triplet exciton fission. In Pc films (as well as C(60)-doped films) this decay channel is suppressed by electron trapping. These results demonstrate the central role of crystallinity and purity in photogeneration processes and will constrain the design of future photovoltaic devices.

AB The phase diagram of DNA linker mediated nanoparticle assemblies was experimentally investigated and constructed. Using small angle x-ray scattering we studied the dependence of the internal structure of assembly on two main system parameters: DNA linker length and the number of linkers per particle. The formation of a crystalline bcc phase was observed for a limited range of linker lengths, while the number of linkers per particle controlled the onset of system crystallization. The influence of linkage defects on crystalline structure was also examined.

TI Selectively Targeting T- and B-Cell Lymphomas: A Benzothiazole
Antagonist of alpha(4)beta(1) Integrin
SO JOURNAL OF MEDICINAL CHEMISTRY
LA English
DT Article
AB Current cancer chemotherapeutic agents clinically deployed today are designed to be indiscriminately cytotoxic, however. achieving selective targeting of cancer malignancies would allow for improved diagnostic and chemotherapeutic tools. Integrin alpha(4)beta(1), a heterodimeric cell surface receptor, is believed to have a low-affinity conformation in resting normal lymphocytes and an activated high-affinity conformation in cancerous cells, specifically T- and B-cell lymphomas. This highly attractive yet poorly understood receptor has been selectively targeted with the bisaryl urea peptidomimetic antagonist 1. However. concerns regarding its preliminary pharmacokinetic (PK) profile provided an impetus to change the pharmacophore from a bisaryl urea to a 2-arylaminobenzothiazole moiety, resulting in an analogue with improved physicochemical properties, solubility, and kidney:tumor ratio while maintaining potency (6; IC50 = 53 pM). The results presented herein utilized heterocyclic and solid-phase chemistry, cell adhesion assay, and in vivo optical imaging using the cyanine dye Cy5.5 conjugate.

TI Determination of Arrhenius and Thermodynamic Parameters for the Aqueous

AB Lactic acid is a major component of the TALSPEAK process planned for use in the separation of trivalent lanthanide and actinide elements. This acid acts both as a buffer and to protect the actinide complexant from radiolytic damage. However, there is little kinetic information on the reaction of water radiolysis species with lactic acid, particularly under the anticipated process conditions of aerated aqueous solution at PH similar to 3, where oxidizing reactions are expected to dominate. Here we have determined temperature-dependent reaction rate constants for the reactions of the hydroxyl radical with lactic acid and the lactate ion. For lactic acid this rate constant is given by the following equation: In k(1) = (23.85 +/- 0.19) - (1120 +/- 54)/T, corresponding to an activation energy of 9.31 +/- 0.45 kJ mol(-1) and a room temperature reaction rate constant of (5.24 +/- 0.35) x 10(8) M(-1) s(-1) (24.0 degrees C). For the lactate ion, the temperature-dependent rate constant is given by 1n k(2) = (24.83 +/- 0.14) - (1295 +/- 42)/T, for an activation energy of 10.76 +/- 0.35 kJ mol(-1) and a room temperature value of (7.77 +/- 0.50) x 10(8) M(-1) s(-1) (22.2 degrees C). These kinetic data have been combined with autotitration measurements to determine the temperature-dependent behavior of the lactic acid pK(a) value, allowing thermodynamic parameters for the acid dissociation to be calculated as Delta H degrees = -10.75 +/- 1.77 kJ mol(-1), Delta S degrees = -103.9 +/- 6.0 J K(-1) mol(-1) and Delta G degrees = 20.24 +/- 2.52 kJ mol(-1) at low ionic strength.

ID INTERNAL-ROTATION; POTENTIAL FUNCTIONS; MOLECULES; ATOM; BARRIERS
AB Gauge-invariant NMR chemical shifts of the C and H sites in ethanol is calculated over a variety of conformational and solvation environments using density functional methods. The effects of different exchange and correlation functionals and different basis sets are systematically explored. While there is often a good correlation between atomic charges, as calculated using population analysis techniques, and calculated chemical shifts, we show that calculated populations can only be used as a rough guide to estimating the magnitude of the chemical shift. To incorporate solvent, we use configurations sampled from a classical molecular dynamics simulation of solvated ethanol. We show that the calculated NMR chemical shift at the alcohol proton converges to the experimental result provided that a sufficient number of solvent molecules are included in the GIAO calculation. The predicted shift is in much better agreement with experiment than the shift predicted from clusters with fully optimized solvation shells because of the tendency of solvents to overbond to the alcohol proton in fully optimized configurations.

AB Using quasielastic neutron scattering, we have investigated diffusion dynamics of protons in the protic ionic liquid, N,N,N',N'-tetramethylguanidinium bis(perfluoroethylsulfonyl)imide, a promising new compound for application as an electrolyte in proton-conducting fuel cells. A temperature range of 30-360 K has been studied. The melting temperature of N,N,N',N'-tetramethylguanidinium bis(perfluoroethylsulfonyl)imide is about 290 K. We have found four distinct dynamic processes. First, the methyl group rotations exhibit broadly distributed dynamics which, on the nanosecond time scale, become visible above approximately 100 K. Second, there is a localized process with a characteristic confinement radius of about 1.6 angstrom, which likely involves protons of the -NH(2) groups. These two processes take place in both solid and liquid phases, even though the methyl group rotations in the liquid phase are likely too fast to be detected in our experiment. Above the melting temperature, there are two new diffusion processes contributing to the dynamics of the liquid phase. Both of them appear to be of translational character. However, only the slower process represents unrestricted translation diffusion. The faster process is better described as spatially restricted translational diffusion with a characteristic confinement radius of about 8 angstrom. It is likely that the long-range proton transfer in N,N,N',N'-tetramethylguanidinium bis(perfluoroethylsulfonyl)imide is associated primarily with the unrestricted translational diffusion process, which is characterized by a diffusion coefficient varying from 0.4 x 10(-10) to 1.4 x 10(-10) m(2)/s in the temperature range of 320-360 K.

AB Aluminoborane compounds AlB4H11, AlB5H12, and AlB6H13 were reported by Himpsl and Bond in 1981, but they have eluded the attention of the worldwide hydrogen storage research community for more than a quarter of a century. These aluminoborane compounds have very attractive properties for hydrogen storage: high hydrogen capacity (i.e., 13.5, 12.9, and 12.4 wt % H, respectively) and attractive hydrogen desorption temperature (i.e., AlB4H11 decomposes at similar to 125 degrees C). We have synthesized AlB4H11 and studied its thermal desorption behavior using temperature-programmed desorption with mass spectrometry, gas volumetric (Sieverts) measurement, infrared (IR) spectroscopy, and solid state nuclear magnetic resonance (NMR). Rehydrogenation of hydrogen-desorbed products was performed and encouraging evidence of at least partial reversibility for hydrogenation at relatively mild conditions is observed. Our chemical analysis indicates that the formula for the compound is closer to AlB4H12 than AlB4H11.

AB In the work described here, a vapor transport method and corresponding in situ oxidation-reduction reaction are used in order to introduce GeOx into Er-doped SnO2 nanofibers for the deliberate purpose of producing a carrier-mediated excitation enhancement pathway into a conducting host. It is demonstrated that the photoluminescence intensity of Er-doped SnO2 nanofibers at 1540 nm can be enhanced via a carrier-mediated mechanism by almost two orders of magnitude after the introduction of this germanium suboxide. Furthermore, with proper fabrication conditions, Ge nanorods can be prepared on the surface of these SnO2 nanofibers.

AB Understanding the structure and properties of buried interfaces in materials and devices is a great challenge in physics, chemistry, and materials science. Here we present density functional theory (DFT) based simulations of interfaces in a diamino-dinitroethylene (DADNE, C(2)H(4)N(4)O(4)) molecular crystal. It is shown that interfaces formed in this material by shear-strain deformations affect the energies and activation barriers of DADNE decomposition and that they may be responsible for triggering explosive decomposition in the crystal. Individual molecules located at the interfaces exhibit lowered activation barriers for structural transformations and decomposition processes, which prompts them to serve as nucleation sites for the overall decomposition of the material possibly leading to a chain reaction and explosion. These results shed light on the molecular nature of the localized hot spots in energetic materials and may provide recommendations for rational design of new materials with tailored properties.

AB We report the investigation of titania (Degussa P25) supported gold catalysts prepared by magnetron sputtering. Catalysts grown on natural fumed titania were structurally unstable, resulting in the rapid coarsening of 2.4 nm gold clusters into large similar to 20 nm gold clusters in a few days at room temperature under normal atmospheric conditions. However, treating the titania support powder to a mock deposition-precipitation process, at pH 4. followed by the subsequent deposition of gold onto this treated powder produced a remarkable enhancement in acid particle stability and a 20-fold enhancement of catalytic activity. Furthermore, it was found that treating the titania under basic conditions (pH 10) resulted in a further enhancement of structural stability and a further doubling of the reaction rate to 0.28 mol of CO/mol of Au center dot s. This enhancement cannot be attributed to removing surface Cl- species front the titania, the formation of oxygen vacancies on the TiO2 surface, or an electronic effect. Instead. it appears to be associated with the formation of strongly bound hydroxyl species on the TiO2 surface. The formation of surface hydroxyls during the deposition-precipitation method is coincidental and contributes significantly to the properties of Au/TiO2 catalysts.

AB Formation and migration of hole polarons in bulk rutile and anatase TiO2 were modeled using density functional theory (DFT) combined with the Marcus/Holstein theory of electron/polaron transfer. We previously applied a similar methodology to model electron polarons and extended the approach to hole polarons. Holes were formed by removal of an O(2p) valence electron, and the quantum mechanical characterization of hole hopping (reorganization energy and electronic coupling) was carried out with the DFT+U method, a method that corrects for self-interaction errors and facilitates charge localization, combined with Hartree-Fock cluster calculations. Several elementary hole transfer processes along various directions were investigated for both rutile and anatase. Hopping along most directions in rutile and along one direction in anatase was found to be adiabatic in character, i.e., thermal processes coupled to phonons. The activation energies for these processes were found to be about twice as large as the activation energy for electron hopping in rutile [Deskins and Dupuis, Phys. Rev. B 2007, 75, 195212], in agreement with experiment that indicates electron diffusivity in TiO2 to be faster than hole diffusivity. Comparison of our calculated rutile hole mobility with experiment shows good agreement (theoretical value of 0. 16 cm(2)/V center dot s at 1300 K). Lattice distortions around hole polarons were found to be larger than around electron polarons. Our results showed also that holes are thermodynamically more stable in the rutile phase, while electrons are more stable in the anatase phase. A hole trapping site with hemibond structure (i.e., a "molecular" polaron with the hole shared between two nonbonded oxygen sites) was also identified in anatase. We also characterized the formation of hole and electron polarons at the (110) surface. The energy barriers for hole and electron hopping at the surface are larger than in the bulk, by similar to 0.07 and similar to 0.11 eV, respectively. These studies form the basis for further development of models to describe polaron transport in TiO2 structures such as surfaces, interfaces, or nonperfect crystals.

AB Fluorescence emission and excitation spectra of [Cm(H2O)(9)](3+) ions with regular and distorted tricapped trigonal prismatic coordination geometries are reported at temperatures of 293 and 20 K. The Cm3+ impurities are incorporated into the hexagonal crystal lattices of the isotypic [M(H2O)(9)](CF3SO3)(3) (M = La (1), Y (2)), and [Y(H2O)(9)](C2H5SO4)(3) (3) salts, and into the low symmetry [La(H2O)(9)]Cl-3 center dot 15-crown-5 center dot H2O (4) salt. Small but significant structural differences in the MO9 polyhedra influence the crystal-field levels of the S-8'(7/2) ground-state and the D-6'(7/2) excited-state multiplets. Thus, the total D-6'(7/2) splitting is smaller in 1-3 (376-393 cm(-1)) than in 4 (430 cm(-1)), which explains the marked blue shifts of the emission spectra of 1-3 to those of 4 and Cm3+ (aq) at 293 K. The transitions between the ground state and the two lowest crystal-field levels of the D-6'(7/2) MUltiPletS in 1-3 give rise to narrow fluorescence lines at the emitting level at 20 K, resolving the crystal-field levels of the ground state as sharp and narrowly spaced lines. The total ground-state splittings in 1 (8.0 cm(-1)), 2 (6.0 cm(-1)), and 3 (7.5 cm(-1)) are about three to four times larger than those for Cm3+ in LaCl3 (2.0 cm(-1)), but four to six times smaller than those for Cm3+ in [Y(H2O)(8)]Cl-3 center dot 15-crown-5 (35 cm(-1)). Inhomogeneous line broadening prevents resolving the ground multiplet levels in 4. Vibronic side bands associated with the S-8'(7/2)-D-6'(7/2) transition are observed in the low temperature emission and excitation spectra. The intensities of these side bands are < 1% of the parent electronic transition, the stronger ones being located below similar to 400 cm(-1) and correspond to various CmO9 skeletal modes. The luminescence lifetimes in 1-4 are between 63 and 74 mu s.

AB The growth of epitaxial SnO2 on (0 0 0 1) sapphire using pulsed laser deposition is examined. X-ray diffraction analysis shows that the films are highly a-axis oriented SnO2 with the rutile structure. Three distinct symmetry-equivalent in-plane epitaxial orientations were observed between the film and substrate. With increasing growth temperature, both the growth rate and surface roughness increase with columnar grain formation. Carrier concentration ranged from 10(17) to 10(19) cm(-3), with mobility of 0.5-3 cm(2)/V s. The resistivity of the films increases with increasing growth temperature, suggesting a lower density of oxygen vacancy-related defects formed during high temperature deposition.

AB Fabrication of high-dielectric-strength antiferroelectric (AFE) films on metallic foils is technically important for advanced power electronics. To that end, we have deposited crack-free Pb(0.92)La(0..08)Zr(0.95)Ti(0.05)O(33) (PLZT 8/95/5) films on nickel foils by chemical solution deposition. To eliminate the parasitic effect caused by the formation of a low-permittivity interfacial oxide, a conductive buffer layer of lanthanum nickel oxide (LNO) was coated by chemical solution deposition on the nickel foil before the deposition of PLZT. Use of the LNO buffer allowed high-quality film-on-foil capacitors to be processed in air. With the PLZT 8/95/5 deposited on LNO-buffered Ni foils, we observed field- and thermal-induced phase transformations of AFE to ferroelectric (FE). The AFE-to-FE phase transition field, E(AF) = 225 kV/cm, and the reverse phase transition field, E(FA) = 190 kV/cm, were measured at room temperature on a approximate to 1.15 mu m-thick PLZT 8/95/5 film grown on LNO-buffered Ni foils. The relative permittivities of the AFE and FE states were approximate to 600 and approximate to 730, respectively, with dielectric loss approximate to 0.04 at room temperature. The Curie temperature was approximate to 210 degrees C . The thermal-induced transition of AFE-to-FE phase occurred at approximate to 175 degrees C. Breakdown field strength of 1.2 MV/cm was measured at room temperature. (C) 2008 Elsevier Ltd. All rights reserved.

TI Prediction of Solids Circulation Rate of Cork Particles in an

SO INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH
LA English
DT Article
ID FLOW
AB Circulating fluidized beds (CFB) are currently used in many industrial processes for noncatalytic and catalytic because its effective control is the key to smooth operation of a CFB system. This paper presents a method for solids flow metering from pressure drop measurements in the standpipe dense phase. A model based on the Ergun equation is developed to predict the solids flow rate and voidage in the dense phase of the standpipe. The profile of the solids flow rate under unsteady state is also presented. With the use of this method, the dynamic response time at different locations along the standpipe of a pilot-scale fluidized bed operating at ambient conditions with 812 mu m cork particles is estimated successfully. Through the use of a pressure balance analysis, solids flow models for the standpipe, riser, and other sections of the flow loop are combined to give an integrated CFB model.

AB Preliminary commercial designs were carried out for a fluidized bed as a CO(2) adsorber and a moving bed as a CO(2) regenerator. Reverse engineering methodology was employed on the basis of a commercial 500 MW supercritical PC power plant whereby the boundaries required for a particular reactor design and configuration could be set. Employing the proposed moving bed for regenerator is. however, not promising because of poor heat transfer, evolution of CO(2) during regeneration, and high pressure drop when small particles are used. If regeneration kinetics is as slow as reported in tens of minutes, the bed height can be quite high and the reactor can be quite costly. In its place, a so-called assisted self-fluidization bed with embedded heat transfer Surface was proposed. Theoretically, there is no reason why the fluidized bed cannot be successfully designed and operated both as an adsorber and a regenerator under proper adsorption and regeneration kinetics. Recent publications, where fluidized beds, circulating fluidized beds, or a combination of them were employed both as an adsorber and a regenerator, were cited. Staging may not be necessary employing the fluidized bed technology because of the capability to control reaction temperature at the optimum operating temperature through embedded heat transfer Surface in the fluidized beds. Even if the staging is necessary, the implementation of staging in fluidized beds at ambient pressure and moderate temperature is relatively easy and with minimum cost penalty. Example designs are presented.

AB Exposure to 7 MPa of helium at room temperature alters the texture of Upper Freeport coal in a lump form. The differences in texture and porosity between coal powder and lumps may affect the transport and interaction of fluids and coal. In this work, the information about the coal texture and micro- and meso-porosity was obtained via the BET, BJH, and Dubinin-Astakhov analyses. We further investigated the free-fluid-phase volume (free-volume) effects due to helium interaction with the powder and the lumps. During the manometric experiment, helium penetration into the dry coal matrix resulted in slow relaxation of pressure. After exposure of coal to helium, there have been no significant changes of the macroscopic dimensions observed and the relaxation process can be attributed to microscopic 'free-volume' effects. Evolution of the sorption-desorption rates indicates that exposure to helium may change the texture and apparent (helium) density of dry coal. (C) 2008 Elsevier B.V. All rights reserved.

AB Laboratory experiments were conducted to investigate the adsorption kinetic behavior of pure and mixed gases (CO2, CH4, approximately equimolar CO2+CH4 mixtures, and He) on a coal sample obtained from the Black Warrior Basin at the Littleton Mine (Twin Pine Coal Company), Jefferson County, west-central Alabama. The sample was from the Mary Lee coal zone of the Pottsville Formation (Lower Pennsylvanian). Experiments with three size fractions (45-150 mu m, 1-2 mm, and 5-10 mm) of crushed coal were performed at 40 degrees C and 35 degrees C over a pressure range of 1.4-6.9 MPa to simulate coalbed methane reservoir conditions in the Black Warrior Basin and provide data relevant for enhanced coalbed methane recovery operations, The following key observations were made: (1) CO2 adsorption on both dry and water-saturated coal is much more rapid than CH4 adsorption; (2) watersaturation decreases the rates of CO2 and CH4 adsorption on coal surfaces, but it appears to have minimal effects on the final magnitude Of CO2 or CH4, adsorption if the coal is not previously exposed to CO2: (3) retention of adsorbed CO2 on coal surfaces is significant even with extreme pressure cycling: and (4) adsorption is significantly faster for the 45-150 mu m size fraction compared to the two coarser fractions.

AB Small angle scattering techniques (SAXS and SANS) have been used to investigate the microstructural properties of the subbituminous coals (R-max 0.42-0.45%) from the Huntly Coalfield, New Zealand. Samples were collected from the two thick (>5 m) coal seams in the coalfield and have been analysed for methane and carbon dioxide sorption capacity, petrography, pore size distribution, specific surface area and porosity.
Specific surface area (SSA) available for carbon dioxide adsorption, extrapolated to a probe size of 4 angstrom, ranged from 1.25 x 10(6) cm(-1) to 4.26 x 10(6) cm(-1) with total porosity varying from 16% to 25%. Porosity was found to be predominantly composed of microporosity, which contributed the majority of the available SSA. Although considerable variation was seen between samples, the results fit well with published rank trends.
Gas holding capacity at the reservoir pressure (approximately 4 MPa) ranged from 2.63 to 4.18 m(3)/t for methane on a dry, ash-free basis (daf) and from 22.00 to 23.72 m(3)/t daf for carbon dioxide. The resulting ratio Of CO2:CH4 ranged from 5.7 to 8.6, with an average of 6.7:1.
Holding capacities for both methane and carbon dioxide on a dry ash free basis (daf) were found to be correlated with sample microporosity. However, holding capacities for the two gases on an as analysed (aa) basis (that is including mineral matter and moisture), showed no such correlation. Carbon dioxide (aa) does show a negative correlation with both specific surface area and microporosity. As the coals have low inorganic matter content, the reversal is thought to be related to moisture which is likely concentrated in the pore size range 12.5-125 angstrom. Methane holding capacity, both daf and aa, correlates with macroporosity, thus suggesting that the holding capacity of micropores is diminished by the presence of moisture in the pores.

AB Small angle neutron scattering techniques have been applied to investigate the phase behavior of CO2 injected into coal and possible changes in the coal pore structure that may result from this injection. Three coals were selected for this study: the Seelyville coal from the Illinois Basin (R-o=0.53%), Baralaba coal from the Bowen Basin (R-o=0.67%), and Bulli 4 coal from the Sydney Basin (R-o=1.42%). The coals were selected from different depths to represent the range of the underground CO2 conditions(from subcritical to supercritical) which may be realized in the deep subsurface environment. The experiments were conducted in a high pressure cell and CO2 was injected under a range of pressure conditions, including those corresponding to in-situ hydrostatic subsurface conditions for each coal. Our experiments indicate that the porous matrix of all coals remains essentially unchanged after exposure to CO2 at pressures up to 200 bar (1 bar=10(5) Pa). Each coal responds differently to the CO2 exposure and this response appears to be different in pores of various sizes within the same, coal. For the Seelyville coal at reservoir conditions (16 degrees C, 50 bar), CO2 condenses from a gas into liquid, which leads to increased average fluid density in the pores (rho(pore)) with sizes(r) 1x10(5)>= r >= 1x10(4) angstrom (rho(pore)approximate to 0.489 g/cm(3)) as well as in small pores with size between 30 and 300 angstrom (rho(pore)approximate to 0.671 g/cm(3)). These values are by a factor of three to four higher than the density of bulk CO2 (rho(CO2)) under similar thermodynamic conditions (rho(CO2)-0.15 g/cm(3)). At the same time, in the intermediate size pores with r approximate to 1000 angstrom the average fluid density is similar to the density of bulk fluid, which indicates that adsorption does not occur in these pores. At in situ conditions for the Baralaba coal (35 degrees C, 100 bar), the average fluid density Of CO2 in all pores is lower than that of the bulk fluid (rho(pore)/rho(CO2)approximate to 0.6). Neutron scattering from the Bulli 4 coal did not show any significant variation with pressure, a phenomenon which we assign to the extremely small amount of porosity of this coal in the pore size range between 35 and 100,000 angstrom.

AB The permeability of coal samples from Pittsburgh Seam was determined using carbon dioxide as the flowing fluid. The confining pressure was varied to cover a wide range of depths. The permeability was determined as a function of exposure time of carbon dioxide while the confining stress was kept constant. The porosities of the coal samples were found to be very low and most of the samples had porosities less than 1%. The permeability of these coal samples was very low-less than 1 mu D. Since the objective of this study was to investigate the influence of CO2 exposure on coal permeability, it was necessary to increase the initial permeability of the coal samples by introducing a fracture. A longitudinal fracture was induced mechanically, and CT scans were taken to ensure that the fracture was present throughout the sample and that the sample was not damaged otherwise during the process. In this study, the permeability of coal was determined by using pressure transient methods. Two types of pressure pulses were used: A-spike and Sine-6 pressure transients. It was first established that the permeability of fractured coal samples did not change with exposure time when an inert gas (Argon) was used as the fluid medium in the experiments. However, the permeability of coal samples decreased significantly when carbon dioxide was used as the fluid medium. This reduction can be attributed to the coal swelling phenomenon. The results show that the permeability reduction in fractured coal samples can be over 90% of the original value, and the exposure time for such reductions can range from 1.5 days up to a week, typically about 2 days under laboratory conditions. The permeability decreased significantly with the increase in confining pressure. The higher confining pressure appears to close internal fractures causing a reduction in permeability.

ID CO2 SEQUESTRATION; CARBON-DIOXIDE; PERMEABILITY; BEHAVIOR; SEAMS
AB Geologic sequestration in deep unmineable coal seams and enhanced coalbed methane production is a promising choice, economically and environmentally, to reduce anthropogenic gases such as carbon dioxide in the atmosphere. Unmineable coal seams are typically known to adsorb large amounts of carbon dioxide in comparison to the sizeable amounts of sorbed methane, which raises the potential for large scale sequestration projects. During the process of sequestration. carbon dioxide is injected into the coalbed and desorbed methane is produced. The coal matrix is believed to shrink when a gas is desorbed and swell when a gas is sorbed, sometimes causing profound changes in the cleat porosity and permeability of the coal seam. These changes may have significant impact on the reservoir performance, Therefore, it is necessary to understand the combined influence of swelling and shrinkage, and geomechanical properties including elastic modulus, cleat porosity, and permeability of the reservoir.
The present paper deals with the influence of swelling and shrinkage on the reservoir performance, and the geomechanical response of the reservoir system during the process of geologic sequestration of carbon dioxide and enhanced coalbed methane production in an actual field project located in northern New Mexico. A three-dimensional swelling and shrinkage model was developed and implemented into an existing reservoir model to understand the influence of geomechanical parameters, as well as swelling and shrinkage properties, on the reservoir performance. Numerical results obtained from the modified simulator were compared to available measured values from that site and previous studies. Results show that swelling and shrinkage, and the combination of geomechanical and operational parameters, have a significant influence on the performance of the reservoir system.

DE CO(2) sequestration in coal; Economic evaluation; Enhanced coalbed
methane; Unminable coal seams
AB Unminable coalbeds are potentially large storage reservoirs for the sequestration of anthropogenic CO(2) and offer the benefit of enhanced methane production, which can offset some of the costs associated with CO(2) sequestration. The objective of this paper is to study the economic feasibility Of CO(2) sequestration in unminable coal seams in the Powder River Basin of Wyoming. Economic analyses Of CO(2) injection options are compared. Results show that injecting flue gas to recover methane from CBM fields is marginally economical; however, this method will not significantly contribute to the need to sequester large quantities Of CO(2) Separating CO(2) from flue gas and injecting it into the unminable coal zones of the Powder River Basin seam is currently uneconomical, but can effectively sequester over 86,000 tons (78,200 Mg) Of CO(2) per acre while recovering methane to offset costs. The cost to separate CO(2) from flue gas was identified as the major cost driver associated with CO(2) sequestration in unminable coal seams. Improvements in separations technology alone are unlikely to drive costs low enough for CO(2) sequestration in unminable coal seams in the Powder River Basin to become economically viable. Breakthroughs in separations technology could aid the economics, but in the Powder River Basin they cannot achieve the necessary cost reductions for breakeven economics without incentives.

AB We propose that the extraordinarily high superconducting transition temperatures in the cuprates are driven by an exact mapping of the d(x2-y2) Cooper-pair wavefunction onto the incommensurate spin fluctuations observed in neutron-scattering experiments. This is manifested in the direct correspondence between the inverse of the incommensurability factor d seen in inelastic neutron-scattering experiments and the measured superconducting coherence length xi(0). Strikingly, the relationship between xi(0) and delta is valid for both La2-xSrxCuO4 and YBa2Cu3O7-x, suggesting a common mechanism for superconductivity across the entire hole-doped cuprate family. Using data from recent quantum-oscillation experiments in the cuprates, we propose that the fluctuations responsible for superconductivity are driven by a Fermi-surface instability. On the basis of these findings, one can specify the optimal characteristics of a solid that will exhibit 'high Tc' superconductivity.

ID MAGNETIC-PROPERTIES
AB Bimetallic oxalates are molecule-based magnets with transition-metal ions M(II) and M'(III) arranged on an open honeycomb lattice. Performing a Holstein-Primakoff expansion, we obtain the spin-wave spectrum of antiferromagnetically coupled bimetallic oxalates as a function of the crystal-field angular momentum L2 and L3 on the M(II) and M'(III) sites. Our results are applied to the Fe(II) Mn(III), Ni(II) Mn(III) and V(II) V(III) bimetallic oxalates, where the spin-wave gap varies from 0 meV for quenched angular momentum to as high as 15 meV. The presence or absence of magnetic compensation appears to have no effect on the spin-wave gap.

AB Magnetic and electrical nanowires are two important materials in the development of futuristic nanoelectronics, data storage media and nanosensors. Ni and Au nanowires with a diameter of a few tens of nanometres have been fabricated using deoxyribonucleic acid (DNA) molecules as a template through nanoparticle-controlled electroless deposition (ELD). Nanowire precursors, 1-3 nm Pt(0)-DNA and 1.4 nm Au(0)-DNA, were assembled using two different methods. Chemical reduction was used to deposit Pt(0) particles on DNA which catalyzed Ni nanowire growth. Positively charged Au nanoparticles were directly assembled on phosphate groups of DNA which were stretched and anchored between micrometre-spaced electrodes. Electrical measurement has shown that Au nanowires, catalyzed by Au(0)-DNA in a subsequent ELD, are highly conductive and show linear I-V characteristics. The major factors for the resistivity of nanowires were discussed in detail. This work involves important aspects in the field of DNA-based self-assembly, such as DNA and surface interaction, DNA nanoparticle assembly and electrical property of fabricated nanowires.

ID SILICON-ON-INSULATOR
AB We present first experimental results from a new diffraction depth-sensitive imaging technique. It is based on the diffraction of a focused x-ray beam from a crystalline sample and recording the intensity pattern on a high-resolution CCD detector positioned at a focal plane. Structural non-uniformity inside the sample results in a region of enhanced intensity in the diffraction pattern. The technique was applied to study silicon-on-insulator thin layers of various thicknesses which revealed a complex strain profile within the layers. A circular Fresnel zone plate was used as a focusing optic. Incoherent diffuse scattering spreads out of the diffraction plane and results in intensity recorded outside of the focal spot providing a new approach to separately register x-rays scattered coherently and incoherently from the sample.

ID YEAST GENOME
AB Background: Biological studies involve a growing number of distinct high-throughput experiments to characterize samples of interest. There is a lack of methods to visualize these different genomic datasets in a versatile manner. In addition, genomic data analysis requires integrated visualization of experimental data along with constantly changing genomic annotation and statistical analyses.
Results: We developed GenomeGraphs, as an add-on software package for the statistical programming environment R, to facilitate integrated visualization of genomic datasets. GenomeGraphs uses the biomaRt package to perform on-line annotation queries to Ensembl and translates these to gene/transcript structures in viewports of the grid graphics package. This allows genomic annotation to be plotted together with experimental data. GenomeGraphs can also be used to plot custom annotation tracks in combination with different experimental data types together in one plot using the same genomic coordinate system.
Conclusion: GenomeGraphs is a flexible and extensible software package which can be used to visualize a multitude of genomic datasets within the statistical programming environment R.

AB We describe the successful development of a procedure for the step-by-step formation of a reactive, multilayer polymer scaffold incorporating polymers based on 2-vinyl-4,4-dimethylazlactone (VDMA) on a silicon wafer and the characterization of these materials. Also discussed is the development of a procedure for the nonsite specific attachment of a biomolecule to a modified silicon wafer, including scaffolds modified via drop-on-demand (DOD) inkjet printing. VDMA-based polymers were used because of their hydrolytic stability and ability of the pendant azlactone rings to form stable covalent bonds with primary amines without byproducts via nucleophilic addition. This reaction proceeds without a catalyst and at room temperature, yielding a stable amide linkage, which adds to the ease of construction expected when using VDMA-based polymers. DOD inkjet printing was explored as an interesting method for creating surfaces with one or more patterns of biomolecules because of the flexibility and ease of pattern design.

AB Steric effects are investigated in the reaction of aryl radicals with surfaces. The electrochemical reduction of 2-, 3-, 4-methyl, 2-methoxy, 2-ethyl, 2,6-, 2,4-, and 3,5-dimethyl, 4-tert-butyl, 3,5-bis-tert-butyl benzenediazonium, 3,5-bis(trifluoromethyl), and pentafluoro benzenediazonium tetrafluoroborates is examined in acetonitrile solutions. It leads to the formation of grafted layers only if the steric hindrance at the 2- or 2,6-position(s) is small. When the 3,5-positions are crowded with tert-butyl groups, the growth of the organic layer is limited by steric effects and a monolayer is formed. The efficiency of the grafting process is assessed by cyclic voltammetry, X-ray photoelectron spectroscopy, infrared, and ellipsometry. These experiments, together with density functional computations of bonding energies of substituted phenyl groups on a copper surface, are discussed in terms of the reactivity of aryl radicals in the electrografting reaction and in the growth of the polyaryl layer.

TI Nanosilica Formation At Lipid Membranes Induced by the Parent Sequence

MORPHOGENESIS; POLYAMINES; VESICLES; CARBON; FORM
AB Diatoms are unicellular eukaryotic algae found in fresh and marine water. Each cell is surrounded by an outer shell called a frustule that is composed of highly structured amorphous silica. Diatoms are able to transform silicic acid into these sturdy intricate structures at ambient temperatures and pressures, whereas the chemical synthesis of silica-based materials typically requires extremes of temperature and pH. Cationic polypeptides, termed silica affinity proteins (or silaffins), recently identified from dissolved frustules of specific species of diatoms, are clearly involved and have been shown to initiate the formation of silica in solution. The relationship between the local environment of catalytic sites on these peptides, which can be influenced by the amino acid sequence and the extent of aggregation, and the structure of the silica is not understood. Moreover, the activity of these peptides in promoting silicification at lipid membranes has not yet been clarified. In this work, we developed a model system to address some of these questions. We studied peptide adsorption to Langmuir monolayers and subsequent silicification using X-ray reflectivity and grazing incidence X-ray diffraction. The results demonstrate the lipid affinity of the parent sequence of a silaffin peptide and show that the membrane-bound peptide promotes the formation of an interfacial nanoscale layer of amorphous silica at the lipid-water interface.

AB Atomic force microscopy (AFM) provides a unique capability to image high-resolution architecture and structural dynamics of pathogens (e.g., viruses, bacteria, and bacterial spores) at near-molecular resolution in native conditions. Further development of atomic force microscopy to enable the correlation of pathogen protein surface structures with specific gene products is essential to understand the mechanisms of the pathogen life cycle. We applied an AFM-based immunolabeling technique for the proteomic mapping of macromolecular structures through the visualization of the binding of antibodies, conjugated with nanogold particles, to specific epitopes on Bacillus spore surfaces. This information is generated while simultaneously acquiring the Surface morphology of the pathogen. The immunospecificity of this labeling method was established through the utilization of specific polyclonal and monoclonal antibodies that target spore coat and exosporium epitopes of Bacillus atrophaeus and Bacillus anthracis spores.

AB A permanently microporous metal-organic framework compound with the formula Zn-2(NDC)(2)(diPyTz) (NDC = 2,6-naphthalenedicarboxylate, diPyTz = di-3,6-(4-pyridyl)-1,2,4,5-tetrazine) has been synthesized. The compound, which features a triply catenating, pillared-paddlewheel structure, was designed to be easily chemically reduced (diPyTz sites) by appropriate channel permeants. Reduction was achieved by using the naphthalenide anion, with the accompanying metal cation (Li+, Na+ or K+) serving to dope the compound in extraframework fashion. H, uptake at 1 atm and 77 K increases from 1.12 wt % for the neutral material to 1.45, 1.60, and 1.51 wt % for the Li+-, Na+-, and K+-doped materials, respectively. The isosteric heats of adsorption are similar for all four versions of the material despite the large uptake enhancements for the reduced versions. Nitrogen isotherms were also measured in order to provide insight into the mechanisms of uptake enhancement. The primary mechanism is believed to be dopant-facilitated displacement of catenated frameworks by sorbed H-2. More extensive cation doping decreases the H-2 loading.

AB Molecular imaging enables visualization of specific molecules in vivo and without substantial perturbation to the target molecule's environment. Glycans are appealing targets for molecular imaging but are inaccessible with conventional approaches. Classic methods for monitoring glycans rely on molecular recognition with probe-bearing lectins or antibodies, but these techniques are not well suited to in vivo imaging. In an emerging strategy, glycans are imaged by metabolic labeling with chemical reporters and subsequent ligation to fluorescent probes. This technique has enabled visualization of glycans in living cells and in live organisms such as zebrafish. Molecular imaging with chemical reporters offers a new avenue for probing changes in the glycome that accompany development and disease.

AB The cadherin family of Ca(2+)-dependent cell adhesion proteins are critical for the morphogenesis and functional organization of tissues in multicellular organisms, but the molecular interactions between cadherins that are at the core of cell-cell adhesion are a matter of considerable debate. A widely-accepted model is that cadherins adhere in 3 stages. First, the functional unit of cadherin adhesion is a cis dimer formed by the binding of the extracellular regions of 2 cadherins on the same cell surface. Second, formation of low-affinity trans interactions between cadherin cis dimers on opposing cell surfaces initiates cell-cell adhesion. Third, lateral clustering of cadherins cooperatively strengthens intercellular adhesion. Evidence of these cadherin binding states during adhesion is, however, contradictory, and evidence for cooperativity is lacking. We used single-molecule structural (fluorescence resonance energy transfer) and functional (atomic force microscopy) assays to demonstrate directly that cadherin monomers interact via their N-terminal EC1 domain to form trans adhesive complexes. We could not detect the formation of cadherin cis dimers, but found that increasing the density of cadherin monomers cooperatively increased the probability of trans adhesive binding.

AB Metal-organic frameworks containing an organic fluorophore such as stilbene dicarboxylate emit prompt visible light when they interact with ionizing radiation (e.g., high-energy protons or alpha particles). A completely new class of scintillation materials is created by this development, with the potential to rationally tailor properties for specific radiation detection applications.

ID X-RAY-DIFFRACTION; CARBON NANOTUBES
AB The detailed interactions between hydrated bromine ions and a number of graphene-like surfaces are elucidated for the first time. A common edge site that exhibits preferential binding of bromide is observed for all materials. The local structure around the hydrated bromide in this interaction region is that of the ion binding to a zigzag, convex site on the graphene sheet edge, consistent with predictions of a recent theoretical model.

AB The chemical and electronic surface structure of ZnO:Zn3N2 (ZnO:N) thin films with different N contents was investigated by soft x-ray emission spectroscopy. Upon exposure to ambient air (in contrast to storage in vacuum), the chemical and electronic surface structure of the ZnO:N films changes substantially. In particular, we find that the Zn3N2/(Zn3N2+ZnO) ratio decreases with exposure time and that this change depends on the initial N content. We suggest a degradation mechanism based on the reaction of the Zn3N2 content with atmospheric humidity.

AB Observations of dielectric breakdown in Si-rich silicon nitride indicate that it is initiated by threshold field trap ionization. The films exhibit the charge transport mechanism of Poole-Frenkel emission with a compositionally dependent ionization potential ranging from 0.58 to 1.22 eV. Similar to silicon oxynitride, the barrier lowering energy at the point of dielectric breakdown is correlated with within similar to 2kT of the ionization potential, thus revealing a dual role for bulk traps in the film: regulating charge transport and retarding hot electron generation. Additionally, a semiempirical expression is developed that accurately predicts the compositional dependence of the breakdown field.

AB Improved performance of organic light-emitting diodes (OLEDs) was achieved by implementing a carbon nanotube (CNT) layer at the cathode-organic interface, spin coated between the organic layer and the cathode. The small geometry of CNTs could enable the enhancement of the electric field around them, thus increasing electron injection efficiency from the cathode to the organic layer. In addition, as measured from the x-ray absorption and emission spectroscopy, incorporation of CNT could reduce the lowest unoccupied molecular orbital of the organic material at the cathode-organic interface, thus effectively decreasing the barrier for electron injection. Increased electron injection and luminance characteristics were demonstrated for both polymer and small molecule based OLED devices.

AB In this letter we describe the development of coda wave interferometry to determine acoustoelastically derived third order nonlinear coefficients of a highly complex material, concrete. Concrete, a structurally heterogeneous and volumetrically mechanically damaged material, is an example of a class of materials that exhibit strong multiple scattering as well as significant elastic nonlinear response. We show that intense scattering can be applied to robustly determine velocity changes at progressively increasing applied stress using coda wave interferometry, and thereby extract nonlinear coefficients.

AB As femtosecond lasers emerge as viable tools for advanced microscale materials processing, it becomes increasingly important to understand the characteristics of materials resulting from femtosecond laser microablation or micromachining. We conducted transmission electron microscopy experiments to investigate crater structures in silicon produced by repetitive high power femtosecond laser ablation. Comparable experiments of nanosecond laser ablation of silicon were also performed. We found that an amorphous silicon layer that is typically produced in nanosecond laser ablation is absent when the material is irradiated by high power femtosecond laser pulses. Instead, only a defective single crystalline layer was observed in the high power femtosecond laser-ablated silicon crater. Possible mechanisms underlying the formation of the defective single crystalline phase are discussed.

AB We fabricated quasi-one-dimensional Fe chains on a 4 degrees miscut Si (111) substrate with a Pb film as a buffer layer. The magnetic properties and morphology of Fe chains were investigated by means of scanning tunneling microscope (STM) and surface magneto-optical Kerr effect (SMOKE). STM images show that Fe chains are formed by Fe random islands along the steps of the Pb film due to step decoration. SMOKE data indicate that the Fe chains exhibit in-plane uniaxial magnetic anisotropy along the step direction. The effective in-plane uniaxial anisotropy constant at room temperature was determined by means of electron spin resonance.

AB Deformation induced grain growth has been widely reported in nanocrystalline materials. However, the grain growth mechanism remains an open question. This study applies high-pressure torsion to severely deform bulk nanocrystalline Ni-20 wt % Fe disks and uses transmission electron microscopy to characterize the grain growth process. Our results provide solid evidence suggesting that high pressure torsion induced grain growth is achieved primarily via grain rotation for grains much smaller than 100 nm. Dislocations are mainly seen at small-angle subgrain boundaries during the grain growth process but are seen everywhere in grains after the grains have grown large.

AB The portable NMR community has introduced advances that have allowed for a variety of studies. Imaging of static and moving objects has almost become standardized. The inherent static field gradients of portable systems have, however, limited such studies to imaging of slices perpendicular to the main gradient; full volume imaging in transportable, open systems has not been actively pursued. We present a true three-dimensional image of a phantom in an ex situ, electromagnet-based system. The basic concepts and designs put forth here extend in a straightforward fashion to higher fields and imaging of larger samples by ex situ methodologies. (C) 2008 Elsevier B.V. All rights reserved.

AB The molecular structure of the spontaneously assembled supramolecular cluster [M(4)L(6)](n-) has been explored with different metals (M = Ga(III), Fe(III), Ti(IV)) and different encapsulated guests (NEt(4)(+), BnNMe(3)(+), Cp(2)CO(+), CP(2)(star)Co(+)) by X-ray crystallography. While the identity of the metal ions at the vertices of the M(4)L(6) structure is found to have little effect on the assembly structure, encapsulated guests significantly distort the size and shape of the interior cavity of the assembly. Cations on the exterior of the assembly are found to interact with the assembly through either pi-pi, cation-pi, or CH-pi interactions. In some cases, the exterior guests interact with only one assembly, but cations with the ability to form multiple pi-pi interactions are able to interact with adjacent assemblies in the crystal lattice. The solvent accessible cavity of the assembly is modeled using the rolling probe method and found to range from 253-434 angstrom(3), depending on the encapsulated guest. On the basis of the volume of the guest and the volume of the cavity, the packing coefficient for each host-guest complex is found to range from 0.47-0.67.

ID FREE-ELECTRON LASER; ABLATION; RADIATION; VACUUM; NM
AB We report the first observation of single-shot soft x-ray laser induced desorption occurring below the ablation threshold in a thin layer of poly ( methyl methacrylate) - PMMA. Irradiated by the focused beam from the Free-electron LASer in Hamburg ( FLASH) at 21.7nm, the samples have been investigated by atomic-force microscope (AFM) enabling the visualization of mild surface modifications caused by the desorption. A model describing non-thermal desorption and ablation has been developed and used to analyze single-shot imprints in PMMA. An intermediate regime of materials removal has been found, confirming model predictions. We also report below-threshold multiple-shot desorption of PMMA induced by high-order harmonics (HOH) at 32nm. Short-time exposure imprints provide sufficient information about transverse beam profile in HOH's tight focus whereas long-time exposed PMMA exhibits radiation-initiated surface hardening making the beam profile measurement infeasible.

ID DOUBLE-CRYSTAL DIFFRACTOMETER; SMALL-ANGLE SCATTERING; INSTRUMENT;
PERFORMANCE; PROFILES; CURVES
AB Using the neutron time-of-flight (TOF) technique, We have examined the reason for the dramatic departure of experimental results from the Darwin and Ewald reflectivity functions in the far wings. The scattering from Si(111) single- and triple-bounce crystals set Lip at the Bragg angle 0(B) = 24.4 degrees was dispersed in time-of-flight in the wavelength range 0.3 < lambda < 3.0 angstrom. The experiment reveals admixture of the single-scattered Bragg peaks and thermal diffuse scattering (TDS) originating at lambda < 0.6 angstrom in the spectrum registered from a triple-bounce crystal. Our study explains the discrepancy between the theory and the experimental results reported in many neutron Studies and proves the validity of the Darwin and Ewald theories in the far wings.

TI Measurement of sigma(p(p)over-bar -> Z plus X)Br(Z -> tau(+)tau(-)) at
root s=1.96 TeV
SO PHYSICS LETTERS B

ID DETECTOR
AB We present a measurement of the cross section for Z boson production times the branching fraction to tau lepton pairs sigma(p (p) over bar -> Z + X)Br(Z -> tau(+)tau(-)) in p (p) over bar collisions at root s = 1.96 TeV. The measurement is performed in the channel in which one tau lepton decays into a muon and neutrinos. and the other tau lepton decays hadronically or into an electron and neutrinos. The data sample corresponds to an integrated luminosity of 1.0 fb(-1) collected with the DO detector at the Fermilab Tevatron Collider. The sample contains 1511 candidate events with an estimated 20% background from jets or muons misidentified as tau leptons. We obtain sigma . Br = 240 +/- 8 (star) +/- 12 (sys) +/- 15 (lum) pb, which is consistent with the standard model prediction. (C) 2008 Elsevier B.V. All rights reserved.

AB Rotational bands in Ru-108,Ru-110,Ru-112 have been investigated by means of gamma-gamma-gamma and gamma-gamma(theta) coincidences of prompt gamma rays emitted in the spontaneous fission of Cf-252. The positive parity bands are described by different versions of IBA, where Ru-108 is best described as a gamma-soft nucleus whereas Ru-110,Ru-112 these are more like rigid triaxial rotors. New Delta I = 1 negative parity doublet bands are found. In case of Ru-110,Ru-112, these are interpreted as soft chiral vibrations. Many of the experimental findings can be explained by microscopic calculations that combine the TAC mean-field with random phase approximation but a simple geometrical explanation is not apparent.

ID PAIR PRODUCTION; PHENIX; MESONS; DECAYS
AB PHENIX has measured the electron-positron pair mass spectrum from 0 to 8 GeV/c(2) in p + p collisions at root s = 200 GeV. The contributions from light meson decays to e(+)e(-) pairs have been determined based on measurements of hadron production cross sections by PHENIX. Within the systematic uncertainty of similar to 20% they account for all e(+)e(-) pairs in the mass region below similar to 1 GeV/c(2). The e(+)e(-) pair yield remaining after subtracting these contributions is dominated by semileptonic decays of charmed hadrons correlated through flavor conservation. Using the spectral shape predicted by PYTHIA, we estimate the charm production cross section to be 544 +/- 39(stat) +/- 142(syst) +/- 200(model) pb. which is consistent with QCD calculations and measurements of single leptons by PHENIX.

AB We consider the effects of heavy Majorana neutrinos N with sub-TeV masses and argue that the mere observation of these particles Would be a signal of physics beyond the minimal seesaw mechanism. We describe the N interactions rising ail effective Lagrangian and exhibit the complete set of effective operators of dimension <= 6 involving the N and Standard Model fields. We argue that these interactions can be relatively easy to track at high-energy colliders. For example, we find that new physics (beyond the N) at the TeV-scale can yield thousands of characteristic same-sign lepton number violating l(+) l(+) jj events (j = light jet) at the LHC if m(N) less than or similar to 600 GeV, which can also have a distinctive forward-backward asymmetry signal; even the Tevatron has good prospects for this signature if m(N) less than or similar to 300 GeV.

TI Structure and Proposed Activity of a Member of the VapBC Family of
Toxin-Antitoxin Systems VapBC-5 FROM MYCOBACTERIUM TUBERCULOSIS
SO JOURNAL OF BIOLOGICAL CHEMISTRY
LA English

AB In prokaryotes, cognate toxin-antitoxin pairs have long been known, but no three-dimensional structure has been available for any given complex from Mycobacterium tuberculosis. Here we report the crystal structure and activity of a member of the VapBC family of complexes from M. tuberculosis. The toxin VapC-5 is a compact, 150 residues, two domain alpha/beta protein. Bent around the toxin is the VapB-5 antitoxin, a 33-residue alpha-helix. Assays suggest that the toxin is an Mg-enabled endoribonuclease, inhibited by the antitoxin. The lack of DNase activity is consistent with earlier suggestions that the complex represses its own operon. Furthermore, analysis of the interactions in the binding of the antitoxin to the toxin suggest that exquisite control is required to protect the bacteria cell from toxic VapC-5.

AB We measured overloaded band profiles for a series of time compounds (phenol, caffeine, 3-phenyl 1-propanol, 2-phenylbutyric acid, amphetamine. aniline, benzylamine, p-toluidline, and procainamidium chloride) on columns packed with four different C(18)-bonded packing materials: XTerra-C(18), Gemini-C(18), Luna-C(18)(2), and Halo-C(18), using buffered methanol-water mobile phases. The (S)(W)pH of the mobile phase was increased from 2.6 to 11.3. The buffer concentration (either phosphate, acetate, or carbonate buffers) was set constant at values below the maximum concentration of the sample in the band. The influence of the surface chemistry of the packing material on the retention and the shape of the peaks was investigated. Adsorbents having a hybrid inorganic/organic structure tend to give peaks exhibiting moderate or little tailing. The retention and the shape of the band profiles can easily be interpreted at (S)(W)pHs that are well above or well below the (S)(W)pK(a) of the compound studied. In contrast, the peak shapes in the intermediary pH range (i.e., close to the compound (S)(W)pK(a)) have rarely been studied. These shapes reveal the complexity of the competitive adsorption behavior of couples of acido-basic conjugated compounds at (S)(W)pHs that are close to their (S)(W)pK(a). They also reveal the role of the buffer capacity on the resulting peak shape. With increasings (S)(W)pH, the overloaded profiles are first langmuirian (isotherm type I) at lows (S)(W)pHs, they become S-shaped (isotherm type II), then anti-langmuirian (isotherm type III), S-shaped again at intermediate (S)(W)pHs, and finally return to a langmuirian shape at high (S)(W)pHs. A new general adsorption isotherm model that takes into account the dissociation equilibrium of conjugated acidic and basic species in the bulk mobile phase accounts for these transient band shapes. An excellent agreement was achieved between experimental profiles and those calculated with a two-sites adsorption isotherm model at all (S)(W)pHs. The neutral species adsorbs strongly on a first type of sites that have a high density while the ionic species adsorb preferentially oil a second type of sites that have a very low density. The evolution of the peak shape when the (S)(W)pH changes from acidic to basic is well explained by the weak buffer capacity of the mobile phase used compared to the concentration of the eluted compounds.

AB A self-assembled supramolecular host catalyzes the hydrolysis of acetals in basic aqueous solution. The mechanism of hydrolysis is consistent with the Michaelis-Menten kinetic model. Further investigation of the rate-limiting step of the reaction revealed a negative entropy of activation (Delta S(double dagger) = -9 cal mol(-1) K(-1)) and an inverse solvent isotope effect (k(H(2)O)/k(D(2)O) = 0.62). These data suggest that the mechanism of hydrolysis that takes place inside the assembly proceeds through an A-2 mechanism. in contrast to the A-1 mechanism operating in the uncatalyzed reaction. Comparison of the rates of acetal hydrolysis in the assembly with the rate of the reaction of unencapsulated substrates reveals rate accelerations of up to 980 over the background reaction for the substrate 1,1-diethoxyethane.

DE Correlation; equilibrium; game theory; mediation
AB We study the relationship between the social cost of correlated equilibria and the social cost of Nash equilibria. In contrast to previous work focusing on the possible benefits of a benevolent mediator, we define and bound the Price of Mediation (PoM): the ratio of the cost of the worst correlated equilibrium to the cost of the worst Nash. We observe that in practice, the heuristics used for mediation are frequently non-optimal, and from an economic perspective mediators may be inept or self-interested. Recent results on computation of equilibria also motivate our work.
We consider the Price of Mediation for general games with small numbers of players and pure strategies. For games with two players each having two pure strategies we prove a tight bound of two on the PoM. For larger games (either more players, or more pure strategies per player, or both) we show that the PoM can be unbounded.
Most of our results focus on symmetric congestion games (also known as load balancing games). We show that for general convex cost functions, the PoM can grow exponentially in the number of players. We prove that PoM is one for linear costs and at most a small constant (but can be larger than one) for concave costs. For polynomial cost functions, we prove bounds on the PoM which are exponential in the degree.

DE parallel computing; optimization; discrete event simulation
AB Process Systems Engineering (PSE) is built on the application of computational tools to the solution of physical engineering problems. Over the course of its nearly five decade history, advances in PSE have relied roughly equally on advancements in desktop computing technology and developments of new tools and approaches for representing and solving problems (Westerberg, 2004). Just as desktop computing development over that period focused on increasing the net serial instruction rate, tool development in PSE has emphasized creating faster general-purpose serial algorithms. However, in recent years the increase in net serial instruction rate has slowed dramatically, with processors first reaching an effective upper limit for clock speed and now approaching apparent limits for microarchitecture efficiency. Current trends in desktop processor development suggest that future performance gains will occur primarily through exploitation of parallelism. For PSE to continue to leverage the "free" advancements from desktop computing technology in the future, the PSE toolset will need to embrace the use of parallelization. Unfortunately, "parallelization" is more than just identifying multiple things to do at once.
Parallel algorithm design has two fundamental challenges: first, to match the characteristics of the parallelizable problem workload to the capabilities of the hardware platform, and second to properly balance parallel computation with the overhead of communication and synchronization on that platform. The performance of any parallel algorithm is thus a strong function of how well the characteristics of the problem and algorithm match those of the hardware platform on which it will run. This has led to a proliferation of highly specialized parallel hardware platforms, each designed around specific problems or problem classes.
While every platform has its own unique characteristics, we can group current approaches into six basic classes: symmetric multiprocessing (SMP), networks of workstations (NOW), massively parallel processing (MPP), specialized coprocessors, multi-threaded shared memory, and hybrids that combine components of the first five classes. Perhaps the most familiar of these is the SMP architecture, which forms the bulk of current the desktop and workstation market. These systems have multiple processing units (processors and/or cores) controlled by a single operating system image and sharing a single common shared memory space. While SMP systems provide only a modest level of parallelism (typically 2-16 processing units), the existence of shared memory and full-featured processing units makes them perhaps the most straightforward development platform. A challenge of SMP platforms is the discrepancy between the speed of the processor and the memory system: both latency and overall memory bandwidth limitations can lead to processors idling waiting for data. Clusters, a generic term for coordinated groups of independent computers (nodes) connected with high-speed networks, provide the opportunity for a radically different level of parallelism, with the largest clusters having over 25,000 nodes and 100,000 processing units. The challenge with clusters is memory is distributed across independent nodes. Communication and coordination among nodes must be explicitly managed and occurs over a relatively high latency network interconnect. Efficient use of this architecture requires applications that decompose into pseudo-independent components that run with high computation to communication ratios. The level to which systems utilize commodity components distinguishes the two main types of cluster architectures, with NOW nodes running commodity network interconnects and operating systems and MPP nodes using specialized or proprietary network layers or microkernels. Specialized coprocessors, including graphics processing units (GPU) and the Cell Broadband Engine (Cell), are gaining popularity as scientific computing platforms. These platforms employ non-general purpose dependent processing units to speed fine-grained, repetitive processing. Architecturally, they are reminiscent of vector computing, combining very fast access to a small amount of local memory with processing elements implementing either a single-instruction-multiple-data (SIMD) (GPU) or a pipelined (Cell) model. As application developers must explicitly manage both parallelism on the coprocessor and the movement of data to and from the coprocessor memory space, these architectures can be some of the most challenging to program. Finally, multi-threaded shared memory (MTSM) systems represent a fundamental departure from traditional distributed memory systems like NOW and MPP. Instead of a collection of independent nodes and memory spaces, an MTSM system runs a single system image across all nodes, combining all node memory into a single coherent shared memory space. To a developer, the MTSM appears to be a single very large SMP. However, unlike a SMP that uses caches to reduce the latency of a memory access, the MTSM tolerates latency by using a large number of concurrent threads. While this architecture lends itself to problems that are not readily decomposable, effective utilization of MTSM systems requires applications to run hundreds - or thousands - of concurrent threads.
The proliferation of specialized parallel computing architectures presents several significant challenges for developers of parallel modeling and optimization applications. Foremost is the challenge of selecting the "appropriate" platform to target when developing the application. While it is clear that architectural characteristics can significantly affect the performance of an algorithm, relatively few rules or heuristics exist for selecting a platform based solely on application characteristics. A contributing challenge is that different architectures employ fundamentally different programming paradigms, libraries, and tools. Knowledge and experience on one platform does not necessarily translate to other platforms. This also complicates the process of directly comparing platform performance, as applications are rarely portable: software designed for one platform rarely compiles on another without modification, and the modifications may require a redesign of the fundamental parallelization approach. A final challenge is effectively communicating parallel results. While the relatively homogenous environment of serial desktop computing facilitated extremely terse descriptions of a test platform, often limited to processor make and clock speed, reporting results for parallel architectures must include not only processor information, but depending on the architecture, also include operating system, network interconnect, coprocessor make, model, and interconnect, and node configuration.
There are numerous examples of algorithms and applications designed explicitly to leverage specific architectural features of parallel systems. While by no means comprehensive, three current representative efforts are the development of parallel branch and bound algorithms, distributed collaborative optimization algorithms, and multithreaded parallel discrete event simulation. PICO, the Parallel Integer and Combinatorial Optimizer (Eckstein, et al., 2001), is a scalable parallel mixed-integer linear optimizer. Designed explicitly for cluster environments (both NOW and MPP), PICO leverages the synergy between the inherently decomposable branch and bound tree search and the independent nature of the nodes within a cluster by distributing the independent sub-problems for the tree search across the nodes of the cluster. In contrast, agent-based collaborative optimization (Siirola, et al., 2004, 2007) matches traditionally non-decomposable nonlinear programming algorithms to high-latency clusters (e.g. NOWs or Grids) by replicating serial search algorithms intact and unmodified across the independent nodes of the cluster. The system then enforces collaboration through sharing intermediate "solutions" to the common problem. This creates a decomposable artificial meta-algorithm with a high computation to communication ratio that can scale efficiently on large, high latency, low bandwidth cluster environments. For modeling applications, efficiently parallelizing discrete event simulations has presented a longstanding challenge, with several decades of study and literature (Perumalla, 2006). The central challenge in parallelizing discrete event simulations on traditional distributed memory clusters is efficiently synchronizing the simulation time across the processing nodes during a simulation. A promising alternative approach leverages the Cray XMT (formerly called Eldorado; Feo, et al. 2005). The XMT implements an MTSM architecture and provides a single shared memory space across all nodes, greatly simplifying the time synchronization challenge. Further, the fine-grained parallelism provided by the architecture opens new opportunities for additional parallelism beyond simple event parallelization, for example, parallelizing the event queue management.
While these three examples are a small subset of current parallel algorithm design, they demonstrate the impact that parallel architectures have had and will continue to have on future developments for modeling and optimization in PSE.

AB While large-scale nonlinear programming (NLP) has seen widespread use within the process industries, the desire to solve larger and more complex problems drives continued improvements in NLP solvers. Because of physical hardware limitations, manufacturers have shifted their focus towards multi-core and other modern parallel computing architectures, and we must focus efforts on the development of parallel computing solutions for large-scale nonlinear programming. In this paper we briefly describe some existing and emerging architectures for parallel computing and demonstrate the potential of some of these architectures for parallel solution of nonlinear programming problems. In particular, we show the scalability of an integrated design and control problem using two techniques within a multi-core architecture.

AB The recent emergence of dramatically large computational power, spanning desktops with multi-core processors and multiple graphics cards to supercomputers with 10(5) processor cores, has suddenly resulted in simulation-based solutions trailing behind in the ability to fully tap the new computational capacity. Here, we motivate the need for switching the parallel simulation research to a higher gear to exploit the new, immense levels of computational power. The potential for grand-scale real-time solutions is illustrated using preliminary results from prototypes in four example application areas: (a) state- or regional-scale vehicular mobility modeling, (b) very large-scale epidemic modeling, (c) modeling the propagation of wireless network signals in very large, cluttered terrains, and, (d) country- or world-scale social behavioral modeling. We believe the stage is perfectly poised for the parallel/distributed simulation community to envision and formulate similar grand-scale, real-time simulation-based solutions in many application areas.

AB We report the measurement of the K beta(2)/K beta(1) ratio of He-like krypton using the SuperEBIT electron beam ion trap at the Lawrence Livermore National Laboratory. The energy of these lines are about 15 keV, which is twice as high as the energy of such lines measured before. A comparison with theoretical predictions shows poor agreement, confirming the trend uncovered earlier where the measured result is considerably larger than predicted.

AB We have used microcalorimeters built by the NASA/Goddard Space Flight Center and the Lawrence Livermore National Laboratory SuperEBIT electron beam ion trap to measure X-ray emission produced by charge exchange reactions between highly charged ions colliding with neutral helium, hydrogen, and nitrogen gas. Our measurements show the spectral dependence on neutral species and also show the distinct differences between spectra produced by charge exchange reactions and those produced by direct electron-impact excitation. These results are part of an ongoing experimental investigation at the LLNL SuperEBIT facility of charge exchange spectral signatures and can be used to interpret X-ray spectra produced by a variety of laboratory and celestial sources including cometary and planetary atmospheres, the Earth's magnetosheath, the heliosphere, and tokamaks.

Titanium was introduced into the relatively low-temperature, high-density magnetically confined spheromak plasmas using a titanium gettering system. The measurements were done using a high-resolution grazing-incidence spectrometer with a 1200 lines/mm grating and a Photometrics charged-coupled device camera. Spectral lines from the transition array 3s(2)3pk - 3s(2)3p(k-1)3d in argon-like Ti(4+), chlorine-like Ti(5+), and sulfur-like Ti(6+) have been observed in the 240 - 370 angstrom interval.

AB The X-ray signatures of L-shell charge exchange in sulfur and iron were studied in the laboratory. Charge states from S11+ to S14+ and Fe18+ to Fe24+ were created in electron beam ion traps (EBITs) and were left to interact via charge exchange with neutral gases. The measurements were monitored with a high-resolution microcalorimeter spectrometer for sulfur and a moderate-resolution SiLi solid-state detector for iron. Comparison of the charge exchange (CX) spectra with those obtained under electron-impact excitation showed marked differences. In particular, we show that CX shifts the centroid energy of the dominant n = 3 --> n = 2 emission. We explain this by an enhancement of the intensity of the 3s --> 2p transitions and a shift towards lower energy of the 3d --> 2p peak.

AB High-resolution broadband, non-dispersive x-ray calorimeter spectrometers have been under development for spaceflight since 1984. As an offshoot of the significant NASA investment in this technology, we have developed a series of calorimeter instruments for laboratory use and installed them at the Electron Beam Ion Trap (EBIT) facility at the Lawrence Livermore National Laboratory. The calorimeter instruments at EBIT have significantly enhanced the capabilities of our laboratory astrophysics program including broad-band measurements of emission from charge exchange recombination and absolute cross sections for collisional excitation. The first Goddard Space Flight Center (GSFC) calorimeter instrument was installed at the EBIT facility in July of 2000 and has seen two major upgrades. The performance of the instrument has significantly improved from the initial instrument that had a resolving power of similar to 500 at 6 keV, and essentially no quantum efficiency at energies above 20 keV, to the current instrument that has a resolving power of 1350 and 95% quantum efficiency at 6 keV, and a resolving power of 1800 and 32% quantum efficiency at 60 keV.

The measurement was performed with electron beam energies between 35 keV and 85 keV. The hydrogen-like spectrum of iron and nickel was observed, and fully resolved, with the XRS/EBIT x-ray microcalorimeter spectrometer, which allowed for an absolute cross section to be measured by normalizing to the RR x-ray emission. These results are compared to theory.

AB L-shell x-ray emission of Au has been observed of the plasma that flows from reduced-size hohlraums under high-power laser irradiation. In order to provide tools for determining the temperature, charge state distribution and mean charge of such a plasma, we have measured the L-shell emission from highly charged gold ions in the SuperEBIT electron beam ion trap under bombardment by electrons at energies from 10 to 18 keV. The emission was recorded with an x-ray microcalorimeter, featuring an instrumental line width of 10 eV in the region of primary interest. Lines from ironlike Au(53+) through neonlike Au(69+) ions were identified. We find that the strong 3d(5/2) double right arrow 2p(3/2) emission features are well separated for at least the highest 13 charge states and can be used to diagnose the charge state distribution.

ID STATISTICAL ERRORS; SPECTRA; PARAMETERS; SAMPLE
AB Proper application of error analysis techniques remains uncommon in most EXAFS analyses. Consequently, many researchers in the community remain distrustful of parameter-error estimates. Here, we demonstrate the accuracy of conventional methods through r-space fits to simulated data. Error estimates are determined as a function of r by averaging many scan simulations in r-space. The statistical-chi(2) value can then be calculated. Since corresponds to the degrees of freedom in a fit, we check Stern's rule for the number of independent data points in an EXAFS spectra. Finally, we apply these simple methods to real data from a Cu foil, highlighting the overwhelming role of systematic errors in theoretical backscattering functions and pointing to the ultimate power of the EXAFS technique if such errors could be removed.

ID REDUCTION; FE(II)
AB The initial Fe(III) minerals and the secondary mineralization products of Shewanella putrefaciens CN32 grown in the presence of dissolved phosphate and a commercial Fe(III) oxide, nominally nanoparticulate lepidocrocite, were determined using XRD and XAFS. The starting material was transformed by the bacteria from a reddish brown, rust colour mineral to a dark green phase over 90 days. Acid extraction of the bioreduced solids with 0.75 M HCl recovered 83% of the total iron as Fe(II), leaving a solid, acid-resistant phase. The latter was identified as nanoparticulate hematite by EXAFS. Subsequently, the starting Fe(III) phase was determined to be a mixture of 60% lepidocrocite, 26% ferrihydrite, and 14% hematite, using linear combination EXAFS analysis. For the acid-extractable phase, XANES and EXAFS indicated a predominantly Fe(II) valence state and a spectrum consistent with a mixture of brucite-type minerals(e. g., green rust or ferrous hydroxide) and siderite. The observed transformations suggest that in this mixed-mineral system, lepidocrocite and ferrihydrite are readily reducible to green rust and siderite, whereas hematite is less amenable to bacterial reduction. This study also demonstrates the utility of XAFS spectroscopy in the quantitative characterization of dissimilatory metal transformations, particularly in complex systems such as nanoparticulate minerals in hydrated mineral-bacteria assemblages.

ID RAY-ABSORPTION SPECTROSCOPY; SAMPLE
AB The effect of stochastic noise on Extended X-ray Absorption Fine Structure (EXAFS) data measurement, analysis, and fitting is discussed. Stochastic noise reduces the ability to uniquely fit a calculated model to measured EXAFS data. Such noise can be reduced by common methods that increase the signal-to-noise ratio; however, these methods are not always practical. Therefore, predetermined, quantitative knowledge of the level of acceptable stochastic noise when fitting for a particular model system is essential in maximizing the chances of a successful EXAFS experiment and minimizing wasted beamtime. This paper outlines a method to estimate, through simulation, the acceptable level of stochastic noise in EXAFS spectra that still allows a successful test of a proposed model compound.

AB X-ray absorption spectroscopy (XAS) has been used to clarify the thickness-dependent magnetic properties in nanometric CoPt films. We get benefit from the variation of the sampling depth with the grazing angle to investigate the variations of the local order within the film. In order to properly resconstruct the 3D information the experiments were performed either in the in-plane as in the out-of-plane geometries and supported by ab initio calculations. A depth dependence in the chemical order is revealed and the magnetic behavior is interpreted within this framework.

POPULATION; DISRUPTION
AB We discuss the results of 3D simulations of tidal disruptions of white dwarfs by moderate-mass black holes as they may exist in the cores of globular clusters or dwarf galaxies. Our simulations follow self-consistently the hydrodynamic and nuclear evolution from the initial parabolic orbit over the disruption to the build-up of an accretion disk around the black hole. For strong enough encounters (pericentre distances smaller than about 1/3 of the tidal radius) the tidal compression is reversed by a shock and finally results in a thermonuclear explosion. These explosions are not restricted to progenitor masses close to the Chandrasekhar limit, we find exploding examples throughout the whole white dwarf mass range. There is, however, a restriction on the masses of the involved black holes: black holes more massive than 2 x 10(5) M-circle dot swallow a typical 0.6 M-circle dot white dwarf before their tidal forces can overwhelm the star's self-gravity. Therefore, this mechanism is characteristic for black holes of moderate masses. The material that remains bound to the black hole settles into an accretion disk and produces an Xray flare close to the Eddington limit of L-Edd similar or equal to 10(41)erg/s (M-bh/1000 M-circle dot), typically lasting for a few months. The combination of a peculiar thermonuclear supernova, together with an X-ray flare thus whistle-blows the existence of such moderate-mass black holes. The next generation of wide field space-based instruments should be able to detect such events.

AB We describe the various aspects involved in building FastTrans, a scalable, parallel microsimulator for transportation networks that can simulate and route tens of millions of vehicles on real-world road networks in a fraction of real time. Vehicular trips are generated using agent-based simulations that provide realistic, daily activity schedules for a synthetic population of millions of intelligent agents. We use parallel discrete-event simulation techniques and distributed-memory algorithms to scale these simulations to over one thousand compute nodes. We present various optimizations for speeding up simulation execution times, including (i) a set of routing algorithms such as variations of Dijkstra's shortest path algorithm and heuristic-based A* search, and (ii) a number of different partitioning schemes for load balancing, including geographic partitioning (that assigns simulation entities that are geographically close by to the same processor) and scattering (that assigns geographically close by entities to different processors). Our main findings include: (i) A* significantly outperforms other routing algorithms while computing near-optimal paths; (ii) surprisingly, scattering outperforms more sophisticated partitioning schemes by achieving near-perfect load-balancing. With optimized routing and partitioning, FastTrans is able to simulate a full 24 hour work-day in New York - involving over one million road links and approximately 25 million vehicular trips - in less than one hour of wall-clock time on a 512-node cluster.

ID PROCESSOR
AB With increasing numbers of cores, future CMPs (Chip Multi-Processors) are likely to have a tiled architecture with a portion of shared L2 cache on each the and a bank-interleaved distribution of the address space. Although such an organization is effective for avoiding access hot-spots, it can cause a significant number of non-local L2 accesses for many commonly occurring regular data access patterns. In this paper we develop a compile-time framework For data locality optimization via data layout transformation. Using a polyhedral model, the program's localizability is determined by analysis of its index set and array reference functions, followed by non-canonical data layout transformation to reduce non-local accesses for localizable computations. Simulation-based results on a 16-core 2D tiled CMP demonstrate the effectiveness of the approach. The developed program transformation technique is also useful in several other data layout transformation contexts.

AB Coupled problems occur widely in the pure and applied sciences and engineering. Two types of models are becoming more common-multiscale models, which couple physical phenomena operating on different spatiotemporal scales, and multiphysics models, which couple distinct natural phenomena. The modelling of coupled systems is an emerging discipline that is now the focus workshops and conferences. Many groups have created model coupling software, spanning a spectrum ranging from custom-made, problem-specific solutions and application domain-specific frameworks to open-source and commercial generic coupling infrastructure packages.
Constructing complex coupled models from numerous interacting models-or constituents-can be notoriously difficult. Coupled models exhibit knowledge, software, and algorithmic /computational complexity. Interdisciplinary teams are the mechanism used to master knowledge complexity. But how does one grapple with the other two types of complexity? Current practice is an ad hoc approach in which an interdisciplinary group achieves their goal by "just figuring it out" (JFIO). The problem with JFIO is it often begins with a team feeling thwarted and overwhelmed, proceeds without a clear roadmap, entails generous amounts of trial-and-error, and is prone to surprises that can cause delays. Furthermore, in software engineering terms JFIO is of low-level process maturity (e. g., not reproducible).
Coupled systems thus far built typically have relatively few (similar to 5-1 0) constituents. Any attempt to tackle more complex system modelling exercises such as coupling climate to energy and economics models or simulating a whole organism like the human body will require coupling of a significantly larger number of constituents. It is doubtful that JFIO will scale to meet such a challenge.
Ideally, one would like a "cook book" approach to building a coupled model. In response to this desideratum I propose a methodology comprising a series of exercises and associated questions whose object is to define the requirements for a software implementation of a coupled system. This approach is distilled from years of experience as one of the software architects for the coupling infrastructure for the Community Climate SystemModel (CCSM; http://ccsm.ucar.edu) and my involvement in scientific community software framework projects such as the Earth System Modeling Framework (ESMF; http://www.esmf.ucar.edu), the Common Component Architecture (CCA; http://www.cca-forum.org), and Framework Application for Core-Edge Transport Simulation (FACETS; http://facetsproject.org). This analysis technique is also drawn from my own theoretical work on coupled models in which I have devised terminology, notation, and complexity metrics.
I review previous theoretical work on coupling that is relevant to the exercises outlined in this paper. I then propose a checklist to guide a developer through the requirements-gathering and early design processes for a coupled model. This checklist comprises a series of exercises to identify properties of the envisioned coupled system and to identify and analyse its couplings, elucidating their input/output relationships, types, frequency, and estimated overhead imposed on the constituents. The checklist also covers commonly encountered software engineering issues. This is a proposed checklist: The set of exercises and questions may not fit a given problem perfectly; I encourage the reader to extend, prune, or modify them as necessary. I discuss in brief how distributed-memory parallelism (DMP) complicates this analysis. I offer the reader some advice on how the exercises need to be modified for application to DMP. I conclude that the approach is usable for situations in which coupling occurs in a single address space, but under DMP may become sufficiently laborious that automation may be required.

DE Information Theory; Statistics; Climate Data Analysis
AB Model-reality comparison can be viewed in a communications context, with the observed data the "sent message," the model output "received message," and the model the noisy channel over which the message is transmitted (Figure 1). Information theory offers a way to assess literally the "information content" of any system and offers a means for objective quantification of model-observational data fidelity. The Shannon entropy (SE) H (X) is the measure of the amount of uncertainty, variability, or "surprise" present in a system variable X, while the mutual information (MI) I(X;Y) measures the amount of shared information or redundancy between two variables X and Y. Information theory's roots lie in the analysis of communication of data across a noisy channel (Figure 1) and offer a scheme for quantifying how well a message X coming from a transmitter arrives as Y at the receiver. A more general information-theoretic measure of message degradation is the Kullback-Leibler divergence (KLD), which quantifies insufficiency of agreement in the probatility density functions associated with X and Y. The ratio of MI to SE yields the amount of information shared by two datasets versus the information content of one alone. Unfortunately, these information-theoretic techniques work best for discrete rather than continuous systems. The reason is that evaluation of the SE for continuous systems-the differential entropy-does not constitute the continuum limit of the SE. Relative quantities such as the MI and KLD are always valid in the continuum case and are the continuum limit of their discrete counterparts, but they are just that-relative. This begs the question: Is there some way one can benchmark it against some continuum surrogate for the SE? Thus, one faces a choice when using information theory for model validation and intercomparison: (1) adopt coarse-graining strategies that are physically relevant, always aware that computed SE results are specific to a given discretisation, or (2) treat the data as continuous and use the MI combined with some benchmark quantity. In this paper, I adopt strategy (1), and restrict the scope to a variable that has well-agreed-upon discretisations-total cloud cover, which by observational convention is frequently coarse-grained by oktas, tenths, or percent.
I first review basic concepts from information theory. I put forward the notion that the SE is an alternative measure of climate variability, and I evaluate it for reanalysis data and climate model output, producing global maps of the SE. I discuss how to structure sampling from two datasets to construct "messages" for use in information-theoretic model validation. I derive from the SE and MI a pair of fidelity ratios for assessing model-reality fidelity, and evaluate them for total cloud amount. I apply a modified KLD to assess model-reality agreement for local, temporally sampled total cloud and explain the relative strictness of the KLD- and MI-based validation standards. I conclude with a roadmap for analysing and validating the informatics of climate.

ID SHALLOW LAYER MODEL
AB In the last thirty years, both theoretical and experimental investigations supported the analysis of the behavior of dense gases when released in the atmosphere. A few classes of models were developed, differing for the level of detail of the cloud description. For design purposes as well as operator training, we focused on a fast-running model, capable of dealing with complex environments, e. g., chemical facilities and urban areas. Consequently, we opted for the approach based on the shallow water equations, i.e. a system of partial differential equations describing the cloud height, and the spreading velocities in the horizontal directions. The cloud density is inferred from the cloud height and the entrained volume of air. The manuscript discusses the theoretical framework that was implemented to describe the dense gas behavior by means of the shallow water equations.

ID DEUTERON BREAKUP; POTENTIALS
AB Relativistic Faddeev equations for three-body scattering are solved at arbitrary energies in terms of momentum vectors without employing a partial wave decomposition. Relativistic invariance is incorporated within the framework of Poincare invariant quantum mechanics. Based on a Malfliet-Tjon interaction, observables for elastic and breakup scattering are calculated and compared to non-relativistic ones. The convergence of the Faddeev multiple scattering series is investigated at higher energies.

MODELS
AB Measurement of the electric dipole moment (EDM) of H-2 or of He-3 may well come prior to the coveted measurement of the neutron EDM. Exact model calculations for the deuteron are feasible, and we explore here the model dependence of such deuteron EDM calculations. We investigate in a separable potential approach the relationship of the full model calculation to the plane wave approximation, correct an error in an early potential model result, and examine the tensor force aspects of the model results as well as the effect of the short range repulsion found in the realistic, contemporary potential model calculations of Liu and Timmermans. We conclude that, because one-pion exchange dominates the EDM calculation, separable potential model calculations should provide an adequate picture of the H-2 EDM until better than 10% measurements are achieved.

AB We summarize our recent work dealing with the construction of the nucleon-nucleon potential and associated electromagnetic currents up to one loop in chiral effective field theory (chi EFT). The magnetic dipole operators derived from these currents are then used in hybrid calculations of static properties and low-energy radiative capture processes in few-body nuclei. A preliminary set of results are presented for the magnetic moments of the deuteron and trinucleons and thermal neutron captures on p, d, and He-3.

ID ELECTRON-NUCLEUS SCATTERING; FORM-FACTORS; PROTON SCATTERING; PARITY
VIOLATION; BREAKING; MOMENT
AB We have measured parity violating asymmetries in elastic electron-proton and quasi-elastic electron-deuteron scattering at backward electron angle. These measurements have been done at two momentum transfers : Q(2) = 0.22 and 0.63 (GeV/c)(2). Together with our previous forward angle measurement [1], we can extract strange quark contributions to the electromagnetic form factors of the nucleon, as well as nucleon axial form factor coming from the neutral weak interaction. The results indicate a strange quark magnetic contribution close to zero at these Q(2), and a possible non zero strange quark electric contribution for the high Q(2). The first Q(2) behavior measurement of the nucleon axial form factor in elastic electron scattering shows a good agreement with radiative corrections calculated at Q(2) = 0 and with a dipole form using the axial mass determined in neutrino scattering.

AB We have used NICI AO telemetry data to evaluate the T/T conditions at Gemini South and how much T/T residuals an instrument such as GPI will be able to achieve. We have found that spatial aliasing in the NICI WFS produces spurious low frequency power that does not allow us to evaluate whether windshake has a strong contribution. We have also found that the NICI data reveal vibrations at high frequency. In the case of GPI, a similar to 2 mas rms vibration line at 279 Hz in the incoming T/T would dominate the GPI residuals. Excessive windshake and high frequency vibrations are two potential effects that could severely restrict the performance of the future ELTs unless specific controllers are implemented.

acquisition system (SpaceWire)
AB The Polarized Gamma-ray Observer, PoGOLite, is a balloon experiment with the capability of detecting 10% polarization from a 200 mCrab celestial object in the energy range 25-80 keV. During a beam test at KEK-PF in February 2008, 20 detector units were assembled, and a 50 keV X-ray beam with a polarization degree of similar to 90% was irradiated at the center unit. Signals from all 20 units were fed into flight-version electronics consisting of six circuit boards (four waveform digitizer boards, one digital I/O board and one router board) and one microprocessor (SpaceCube), which communicate using a SpaceWire interface. One digitizer board, which can associate up to 8 PDCs, outputs a trigger signal. The digital I/O board handles the trigger and returns a data acquisition request if there is no veto signal (upper or pulse-shape discriminators) from any detector unit. This data acquisition system worked well, and the modulation factor was successfully measured to be similar to 34%. These results confirmed the capabilities of both detector and data-acquisition system for a pathfinder flight planned in 2010.

AB The Electronic Systems Engineering department of the Computing Division at the Fermi National Accelerator Laboratory is developing a data acquisition system that is flexible and powerful enough to meet the demands of pixel and strip detectors for high energy physics applications, but also capable of far broader application utility. To facilitate data acquisition and processing as well as system configuration and control, a stacked system was devised with support for gigabit Ethernet networking. The individual unit within the system is known as a Compact And Programmable daTa Acquisition Node, or CAPTAN. The platform's flexibility is achieved through the ability to stack specialized boards, both vertically and horizontally, to create an integrated system that can be optimized for each user and application. The CAPTAN's main interface is via the Universal Datagram Protocol of the Internet Protocol (UDP/IP). The software solution presented in this paper is at the other end of the UDP/IP interface, and must orchestrate communications. The software must take a modular approach to its command library to give the user a unique and extensible vocabulary with which to communicate with ever advancing readout chip technologies and varying configurations of the specialized boards within a CAPTAN. The software must also handle multiple CAPTANs, each producing gigabits of data per second, thus the solution presented here provides an option to employ distributed computing for CAPTAN network topologies involving large amounts of data.

AB In GEANT4, a Physics List is a consistent set of. physics models that is able to cover all combinations of incident particle type, energy, and target material. Various Physics Lists are possible and useful, according to the specific application domains (e.g. high-energy physics, shielding, space-application, medical physics, etc.), and the best compromise between accuracy and CPU time that the user can accept. Users are allowed to write their own preferred Physics List, but several pre-defined ones are available in GEANT4 for convenience, and indeed they are used by the large majority of users. We present here the Physics Lists that are of interest for high-energy physics applications.

AB Microcalorimeters, cryogenic radiation detectors measuring the energy of photons by the increase of temperature in an absorber, can achieve energy resolutions more than an order of magnitude better than HPGe detectors. However, due to the thermal nature of the pulse generation, the active volume has to be small to maintain good resolution, and pulse decay times are in the order of milliseconds. Consequently, the detection efficiency is low and count rates are limited, especially for commonly used "optimum filter" algorithms that require isolated pulses to measure pulse heights. This is typically solved by building systems with multiple detector elements (arrays). Large arrays, however, require that as much pulse processing as possible be performed at the front end of the electronics to avoid transferring large amounts of waveform data to a host computer for processing.
Pulse processing algorithms developed by XIA LLC for use in digital spectrometers with HPGe detectors, suitably modified for the slower time scale, meet this requirement. In the work reported here, we offline-processed microcalorimeter pulse streams with modified HPGe filter algorithms to provide an initial engineering evaluation of their performance as "practical" filters, capable of achieving sufficiently good energy resolution for most applications while being a) simple enough to be implemented in the readout electronics and b) capable of processing overlapping pulses and thus of achieving higher count rates. In the course of this work, a new filter was developed that uses only a fraction of a pulse while still achieving good energy resolution for very high count rates. The success of this work suggests that future microcalorimeter read-out systems can indeed be built with electronics on which these filters are implemented in multiplexed form, taking advantage of high speed digital signal processing elements to process many channels in parallel at a large reduction in processing cost per channel.

AB In this paper we report on the synthesis and scintillation properties of the ammonium rare-earth haloelpasolites, Cs(NH4)MYX6:Ce3+ (M = Li, Na; X = F, Cl). Due to their high vapor pressure, crystal growth was not feasible. Instead, reactive-atmosphere sintering was used to obtain polycrystalline samples. The ammonium rare-earth haloelpasolite phase was confirmed by X-ray diffraction. Radioluminescence spectra exhibit a broad band peaking in the near-UV due to Ce3+ 5d -> 4f emission. Scintillation decay time spectra under pulsed X-ray excitation show a fast 1.3 ns decay component due to core-valence luminescence in addition to 30 40 ns Ce3+ luminescence. A long decay component with a lifetime of approximately 400 ns, ascribed to self-trapped exciton emission, is present as well. In contrast, the fast decay component of core-valence luminescence is absent in the alpha excited scintillation decay time profiles. Pulse height spectra under fast neutron excitation show evidence of scintillation light produced by neutron - proton scattering.
