The diffraction efficiency was measured by reflectometers in the energy region of 0.6-8.0 keV at synchrotron radiation facilities as well as with an x-ray diffractometer at 8.05 keV. The Co/SiO2 and W/C multilayer gratings showed peak diffraction efficiencies of 0.47 and 0.38 at 6.0 and 8.0 keV, respectively. To our knowledge, the peak efficiency of the W/C multilayer grating is the highest measured with hard x rays. The diffraction efficiency of the Co/SiO2 multilayer gratings was higher than that of the W/C multilayer grating in the energy range of 2.5-6.0 keV. However, it decreased significantly in the energy above the K absorption edge of Co (7.71 keV). For the Co/SiO2 multilayer grating, the measured diffraction efficiencies agreed with the calculated curves assuming arms roughness of similar to 1nm. (c) 2006 Optical Society of America.

TI Rates and properties of Type Ia supernovae as a function of mass and star formation in their host galaxies SO ASTROPHYSICAL JOURNAL LA English DT Article DE distance scale; galaxies : evolution; supernovae : general; surveys ID STELLAR POPULATION SYNTHESIS; FRANCE-HAWAII-TELESCOPE; HUBBLE DEEP FIELD; HIGH-REDSHIFT; LUMINOSITY FUNCTIONS; FORMING GALAXIES; EVOLUTIONARY SYNTHESIS; PHOTOMETRIC REDSHIFTS; FORMATION HISTORY; FAINT GALAXIES AB We show that Type Ia supernovae (SNe Ia) are formed within both very young and old stellar populations, with observed rates that depend on the stellar mass and mean star formation rates (SFRs) of their host galaxies. Models in which the SN Ia rate depends solely on host galaxy stellar mass are ruled out with > 99% confidence. Our analysis is based on 100 spectroscopically confirmed SNe Ia, plus 24 photometrically classified events, all from the Supernova Legacy Survey (SNLS) and distributed over 0.2 < z < 0.75. We estimate stellar masses and SFRs for the SN Ia host galaxies by fitting their broadband spectral energy distributions with the galaxy spectral synthesis code PEGASE.2. We show that the SN Ia rate per unit mass is proportional to the specific SFR of the parent galaxies-more vigorously star-forming galaxies host more SNe Ia per unit stellar mass, broadly equivalent to the trend of increasing SN Ia rate in later type galaxies seen in the local universe. Following earlier suggestions for a simple "two-component" model approximating the SN Ia rate, we find bivariate linear dependencies of the SN Ia rate on both the stellar masses and the mean SFRs of the host systems. We find that the SN Ia rate can be well represented as the sum of 5.3 +/- 1.1 x 10(-14) SNe yr(-1) M-circle dot(-1) and 3.9 +/- 0.7 x 10(-4) SNe yr(-1) (M(circle dot)yr(-1))(-1) of star formation. We also demonstrate a dependence of distant SN Ia light-curve shapes on star formation in the host galaxy, similar to trends observed locally. Passive galaxies, with no star formation, preferentially host faster declining/dimmer SNe Ia, while brighter events are found in systems with ongoing star formation.

We present deep Chandra observations of this jet and analyze the spectral properties of the jet emission from radio through X-rays. We find that the X-ray spectra are significantly softer than the radio spectra in all regions of the bright part of the jet, except for the first bright "knot A," ruling out a model in which the X-ray emission from the entire jet arises from beamed inverse Compton scattering of cosmic microwave background photons in a single-zone jet flow. Within two-zone jet models, we find that a synchrotron origin for the jet's X-rays requires fewer additional assumptions than an inverse Compton model, especially if velocity shear leads to efficient particle acceleration in jet flows.

TI A testable stochastic acceleration model for flares in Sagittarius A SO ASTROPHYSICAL JOURNAL LA English DT Article DE acceleration of particles; black hole physics; Galaxy : center; plasmas; radiation mechanisms : thermal; turbulence ID SUPERMASSIVE BLACK-HOLE; X-RAY FLARE; GALACTIC-CENTER; SGR-A; SUBMILLIMETER EMISSION; PARTICLE-ACCELERATION; INFRARED FLARES; ACCRETION FLOW; ASTERISK; ELECTRONS AB The near-IR and X-ray flares in Sagittarius A* are believed to be produced by relativistic electrons via synchrotron and synchrotron self-Comptonization, respectively. These electrons are likely energized by turbulent plasma waves through second-order Fermi acceleration that, in combination with the radiative cooling processes, produces a relativistic Maxwellian distribution in the steady state. This model has four principal parameters, namely the magnetic field B, the electron density n and temperature gamma(c)m(e)c(2), and the size of the flare region R. In the context of stochastic acceleration, the quantities (RnB)-B-1/2 and gamma Rn-c should remain nearly constant in time. Therefore, simultaneous spectroscopic observations in the NIR and X-ray bands can readily test the model, which, if proven to be valid, may be used to determine the evolution of the plasma properties during an eruptive event with spectroscopic observations in either band or simultaneous flux density measurements in both bands. The formulae can be applied to other isolated or confined systems, where electrons are accelerated to relativistic energies by plasma wave turbulence and produce most of the emission via synchrotron processes.

Water was released from a 3 m x 4 m infiltration plot on the floor of an alcove in the upper tunnel, and seepage was collected from the ceiling of a niche in the lower tunnel. Significant temporal and (particularly) spatial variabilities were observed in both measured infiltration and seepage rates. To analyze the test results, a three-dimensional unsaturated flow model was used. A column-based scheme was developed to capture heterogeneous hydraulic properties reflected by these spatial variabilities observed. Fracture permeability and van Genuchten a parameter [van Genuchten, M.T., 1980. A closed-form equation for predicting the hydraulic conductivity of unsaturated soils. Soil Sci. Soc. Am. J. 44, 892-898] were calibrated for each rock column in the upper and lower hydrogeologic units in the test bed. The calibrated fracture properties for the infiltration and seepage zone enabled a good match between simulated and measured (spatially varying) seepage rates. The numerical model was also able to capture the general trend of the highly transient seepage processes through a discrete fracture network. The calibrated properties and measured infiltration/seepage rates were further compared with mapped discrete fracture patterns at the top and bottom boundaries. The measured infiltration rates and calibrated fracture permeability of the upper unit were found to be partially controlled by the fracture patterns on the infiltration plot (as indicated by their positive correlations with fracture density). However, no correlation could be established between measured seepage rates and density of fractures mapped on the niche ceiling. This lack of correlation indicates the complexity of (preferential) unsaturated flow within the discrete fracture network. This also indicates that continuum-based modeling of unsaturated flow in fractured rock at mesoscale or a larger scale is not necessarily conditional explicitly on discrete fracture patterns.

TI Group analysis, direct numerical simulation and modelling of a turbulent channel flow with streamwise rotation SO JOURNAL OF FLUID MECHANICS LA English DT Article ID LOW-REYNOLDS-NUMBER; CLOSURE AB The turbulent channel flow with streamwise rotation has been investigated by means of several different analytical, numerical, and modelling approaches. Lie group analysis of the two-point correlation equations led to linear scaling laws for the streamwise mean velocity. In addition it was found that a cross-flow in the spanwise direction is induced, which may also exhibit a linear region. By further analysis of the two-point correlation equation, it is shown that all six components of the Reynolds stress tensor are non-zero. In addition certain symmetries and skew-symmetries about the centreline have been established for all flow quantities. All these findings of the analysis have been verified very well by means of direct numerical simulations (DNS). The flow has also been calculated with large-eddy simulations (LES) and second-moment closure models. The dynamic LES captured most of the theoretical and DNS findings quantitatively. Except for one stress component the second-moment closure model was able to capture most of the basic trends, but no quantitative agreement could be achieved.

TI Statistics of subgrid-scale stress states in homogeneous isotropic turbulence SO JOURNAL OF FLUID MECHANICS LA English DT Article ID LARGE-EDDY SIMULATION; NUMERICAL TURBULENCE; STRAIN-RATE; VORTICITY; ALIGNMENT; MODELS; FLOW AB Two parameters are introduced that uniquely characterize the state of a third-order symmetric tensor. We show that the proposed parameters arise from the uniform metric in the matrix space; thus the joint PDF of these parameters can be used to determine the geometrical statistics of any third-order symmetric tensor. We use this joint PDF to describe the states of the subgrid-scale stress, which is of central interest in large-eddy simulation. Direct numerical simulation of forced isotropic turbulence is used in our a priori tests. With the proposed parameterization we can also assess the most probable flow configuration at the scales of motion just above the Kolmogorov scale. We test four different subgrid-scale models in terms of how well they predict the structure, or state, of the subgrid-scale stress. It is found that models based on truncated Taylor series do not produce an adequate distribution of states, even if augmented by a turbulent viscosity term. On the other hand, models based on the scale-similarity assumption predict a distribution of states that is close to actual. C1 Los Alamos Natl Lab, Ctr Nonlinear Studies, Los Alamos, NM 87544 USA.

Trees are prime candidates for the extraction of paleoclimate archives as they can be probed sub-annually, are widely distributed and can live for over 1400 years [Chambers et al., 1998]. However, dendrochronological techniques have found limited applications in the tropics because trees often lack visible growth rings (Whitmore, 1990). Alternative methods exist (dendrometry (DaSilva et al., 2002), radio- and stable isotopes (Evans and Schrag, 2004; Poussart et al., 2004; Poussart and Schrag, 2005), but the derived records are either of short-duration, lack seasonal resolution or are prohibitively labor intensive to produce. Here, we show the first X-ray microprobe synchrotron record of calcium (Ca) from a ringless Miliusa velutina tree from Thailand and use it to estimate the tree's age and growth history. The Ca age model agrees within <= 2 years of bomb-radiocarbon age estimates and confirms that the cycles are seasonal. The amplitude of the Ca annual cycle is correlated significantly with growth and annual Ca maxima correlate with the amount of dry season rainfall. Synchrotron measurements are fast and producing sufficient numbers of replicated multi-century tropical dendrochemical climate records now seems analytically feasible.

The crystal structure, determined at 2.3 angstrom resolution, of a large fragment of Pol III (residues 1-917), reveals a unique chain fold with localized similarity in the catalytic domain to DNA polymerase beta and related nucleotidyltransferases. The structure of Pol III is strikingly different from those of members of the canonical DNA polymerase families, which include eukaryotic replicative polymerases, suggesting that the DNA replication machinery in bacteria arose independently. A structural element near the active site in Pol III that is not present in nucleotidyltransferases but which resembles an element at the active sites of some canonical DNA polymerases suggests that, at a more distant level, all DNA polymerases may share a common ancestor. The structure also suggests a model for interaction of Pol III with the sliding clamp and DNA. C1 Univ Calif Berkeley, Howard Hughes Med Inst, Dept Mol & Cell Biol, Berkeley, CA 94720 USA.

These excitations are observed in X-ray absorption and related spectroscopies. The new method depends on defining pure valence anti-bonding orbitals using, literally, a linear combination of atomic orbitals. Application to the O K-edge excited states of H2O is presented. This analysis is important since Rydberg and valence anti-bonding orbitals will behave differently when a molecule is placed in a condensed environment. (c) 2006 Elsevier B.V. All rights reserved.

Surface wave microseisms are commonly associated with oceanic storms; there are no previous comprehensive body wave observations. The temporal evolution of the surface and body waves was different, indicating a different source mechanism for the two wave types. The body-waves originated in shallow water east of New Orleans and propagated deep inside the Earth. The surface waves have source location that varies with frequency with the lowest frequency surface waves originating west of the hurricane track and the higher frequency ones to the east. The seismic observations are consistent with ocean wave hindcasts and provide clear association of microseism noise with storm activity.

In this study, we describe four x-ray crystal structures and allied functional studies for PikC, the remarkable P450 monooxygenase responsible for production of a number of related macrolide products from the Pik pathway. The results provide important new insights into the structural basis for the C10/C12 and C12/C14 hydroxylation patterns for the 12-(YC-17) and 14-membered ring (narbomycin) macrolides, respectively. This includes two different ligand-free structures in an asymmetric unit (resolution 2.1 angstrom) and two co-crystal structures with bound endogenous substrates YC-17 (resolution 2.35 angstrom) or narbomycin (resolution 1.7 angstrom). A central feature of the enzyme-substrate interaction involves anchoring of the desosamine residue in two alternative binding pockets based on a series of distinct amino acid residues that form a salt bridge and a hydrogen-bonding network with the deoxysugar C3' dimethylamino group. Functional significance of the salt bridge was corroborated by site-directed mutagenesis that revealed a key role for Glu-94 in YC-17 binding and Glu-85 for narbomycin binding. Taken together, the x-ray structure analysis, site-directed mutagenesis, and corresponding product distribution studies reveal that PikC substrate tolerance and product diversity result from a combination of alternative anchoring modes rather than an induced fit mechanism.

That is it depends on the time available for the analysis, on the quality and performance of the pump and hardware and particularly on the maximum pressure at which the pump can deliver the mobile phase to the column, and on the temperature at which the column can be operated. It also depends on the properties of the packing material selected (e.g., its particle size, its pore geometry, and its connectivity) and on the packing method used since it affects the coefficients of the HETP equation. Finally, it depends on the thermal stability of the sample and the packing material. The complexity of the sample also plays an important role in that it determines whether the analysis should be made under isocratic, isothermal conditions, in gradient elution, in temperature programming, or with a combination of both types of programming. The various phenomena that affect column properties and separation performance are discussed. Past achievements suggest that columns providing efficiencies in excess of a million plates in less than 1 day are within the grasp of current technology. The possibility of further advances are considered. (c) 2006 Elsevier B.V. All rights reserved. C1 Univ Tennessee, Dept Chem, Knoxville, TN 37996 USA.

The class IV AC fold is distinct from the previously described folds for class II and class III ACs. The dimeric AC-IV folds into an antiparallel eight-stranded barrel whose connectivity has been seen in only three previous structures: yeast RNA triphosphatase and two proteins of unknown function from Pyrococcus furiosus and Vibrio parahaemolyticus. Eight highly conserved ionic residues E10, E12, K14, R63, K76, K111, D126, and E136 lie in the barrel core and form the likely binding sites for substrate and divalent cations. A phosphate ion is observed bound to R63, K76, K111, and R113 near the center of the conserved cluster. Unlike the AC-II and AC-III active sites that utilize two-Asp motifs for cation binding, the AC-IV active site is relatively enriched in glutamate and features an ExE motif as its most conserved element. Homologs of Y. pestis AC-IV, including human thiamine triphosphatase, span the three kingdoms of life and delineate an ancient family of phosphonucleotide processing enzymes.

TI Spin precession and alternating spin polarization in spin-3/2 hole systems SO PHYSICAL REVIEW LETTERS LA English DT Article ID RELAXATION ANISOTROPY; QUANTUM-WELLS; SEMICONDUCTORS AB The spin density matrix for spin-3/2 hole systems can be decomposed into a sequence of multipoles which has important higher-order contributions beyond the ones known for electron systems [R. Winkler, Phys. Rev. B 70, 125301 ( 2004)]. We show here that the hole spin polarization and the higher-order multipoles can precess due to the spin-orbit coupling in the valence band, yet in the absence of external or effective magnetic fields. Hole spin precession is important in the context of spin relaxation and offers the possibility of new device applications. We discuss this precession in the context of recent experiments and suggest a related experimental setup in which hole spin precession gives rise to an alternating spin polarization.

The coupling of the ferromagnet to the antiferromagnet is modeled by means of an interfacial exchange field. The nonuniformity of the magnetization reversal mode perpendicular to the layers is explicitly included and results in a tilted vortex core (tilted Bloch line). The vortex core tilt results in an asymmetry of the nucleation and annihilation fields, which are calculated as a function of the dot geometry.

TI Low-energy nondipole effects in molecular nitrogen valence-shell photoionization SO PHYSICAL REVIEW LETTERS LA English DT Article ID PHOTOELECTRON ANGULAR-DISTRIBUTIONS; FIXED-IN-SPACE; DIPOLE APPROXIMATION; CROSS-SECTIONS; PHOTO-IONIZATION; DISTRIBUTION PARAMETERS; N-2 MOLECULE; ELECTRONS; INTERFERENCE; QUADRUPOLE AB Observations are reported for the first time of significant nondipole effects in the photoionization of the outer-valence orbitals of diatomic molecules. Measured nondipole angular-distribution parameters for the 3 sigma(g), 1 pi(u), and 2 sigma(u) shells of N-2 exhibit spectral variations with incident photon energies from thresholds to similar to 200 eV which are attributed via concomitant calculations to particular final-state symmetry waves arising from (E1)circle times(M1,E2) radiation-matter interactions first-order in photon momentum. Comparisons with previously reported K-edge studies in N-2 verify linear scaling with photon momentum, accounting in part for the significantly enhanced nondipole behavior observed in inner-shell ionization at correspondingly higher momentum values in this molecule.

TI Missing xy-band Fermi surface in 4d transition-metal oxide Sr2RhO4: Effect of the octahedra rotation on the electronic structure SO PHYSICAL REVIEW LETTERS LA English DT Article ID INSULATOR-TRANSITION; SR2RUO4 AB Electronic structures of the 4d transition-metal oxide compound Sr2RhO4 are investigated by angle-resolved photoemission spectroscopy and density-functional electronic structure calculations. In the measured Fermi surfaces (FS) of Sr2RhO4, the xy-band FS sheet expected from the well-established results of the FS of Sr2RuO4 is missing, the volume of which should be different only by one additional electron for Sr2RhO4. The apparent contradiction is resolved by a careful analysis of the band structure where the rotation of octahedra results in the hybridization of e(g) and t(2g) states and thus plays a key role in the determination of the electronic structure near E-F. The modification of the FS structure due to the distorted lattice is related to the charge transfer among the orbital states and suggested to be relevant to the metal-insulator transition in Ca2-xSrxRuO4.

TI Search for Theta(++) Pentaquarks in the Exclusive Reaction gamma p -> K(+)K(-)p SO PHYSICAL REVIEW LETTERS LA English DT Article ID PHOTOPRODUCTION; DETECTOR; NUCLEON; STATES; CLAS AB The reaction gamma p -> pK(+)K(-) was studied at Jefferson Lab with photon energies from 1.8 to 3.8 GeV using a tagged photon beam. The goal was to search for a Theta(++) pentaquark, a narrow, doubly charged baryon state having strangeness S=+1 and isospin I=1, in the pK(+) invariant mass spectrum. No statistically significant evidence of a Theta(++) was found. Upper limits on the total and differential cross section for the reaction gamma p -> K-Theta(++) were obtained in the mass range from 1.5 to 2.0 GeV/c(2), with an upper limit for a narrow resonance with a mass M-Theta(++)=1.54 GeV/c(2) of about 0.15 nb, 95% C.L.. This result places a stringent upper limit on the Theta(++) width Gamma(++)(Theta)< 0.1 MeV/c(2). C1 Rensselaer Polytech Inst, Troy, NY 12180 USA.

The time-dependent CP asymmetry in B-s -> phi psi, S-psi phi, will be measured with good precision in the first year of CERN Large Hadron Collider (LHC) data taking, which will further constrain the parameter space of many extensions of the SM, in particular, next-to-minimal flavor violation. The CP asymmetry in semileptonic B-s decay, As S-LS(s), is also important to constrain these frameworks, and could give further clues to our understanding the flavor sector in the LHC era. We point out a strong correlation between S-psi phi and A(SL)(s) in a very broad class of new physics models.

TI Nonvanishing energy scales at the quantum critical point of CeCoIn5 SO PHYSICAL REVIEW LETTERS LA English DT Article ID MAGNETIC INSTABILITY; FERMION SYSTEMS; HEAVY; METALS; ELECTRON; SUPERCONDUCTIVITY; TEMPERATURE; ALLOYS AB Heat and charge transport were used to probe the magnetic field-tuned quantum critical point in the heavy-fermion metal CeCoIn5. A comparison of electrical and thermal resistivities reveals three characteristic energy scales. A Fermi-liquid regime is observed below T-FL, with both transport coefficients diverging in parallel and T-FL -> 0 as H -> H-c, the critical field. The characteristic temperature of antiferromagnetic spin fluctuations, T-SF, is tuned to a minimum but finite value at H-c, which coincides with the end of the T-linear regime in the electrical resistivity. A third temperature scale, T-QP, signals the formation of quasiparticles, as fermions of charge e obeying the Wiedemann-Franz law. Unlike T-FL, it remains finite at H-c, so that the integrity of quasiparticles is preserved, even though the standard signature of Fermi-liquid theory fails.

We extract the current experimental determination of the strange electric and magnetic form factors of the proton, as well as the weak axial form factors of the proton and neutron, at Q(2)=0.1 GeV2. Within experimental uncertainties, we find that the strange form factors are consistent with zero, as are the anapole contributions to the axial form factors. Nevertheless, the correlation between the strange and anapole contributions suggest that there is only a small probability that these form factors all vanish simultaneously.

TI Probing spin-flip scattering in ballistic nanosystems SO PHYSICAL REVIEW LETTERS LA English DT Article ID TUNNEL-JUNCTIONS; ACCUMULATION; INJECTION; TRANSPORT; CHARGE; VALVE AB Because spin-flip length is longer than the electron mean-free path in a metal, past studies of spin-flip scattering are limited to the diffusive regime. We propose to use a magnetic double barrier tunnel junction to study spin-flip scattering in the nanometer sized spacer layer near the ballistic limit. We extract the voltage and temperature dependence of the spin-flip conductance G(s) in the spacer layer from magneto-resistance measurements. In addition to spin scattering information including the mean-free path (70 nm) and the spin-flip length (1.0-2.6 mu m) at 4.2 K, this technique also yields information on the density of states and quantum well resonance in the spacer layer.

The intensity of electrons ( 20 - 200 keV) were first observed to increase for perpendicular pitch angles ( pancake distribution), then evolve into isotropic distributions, then further evolve into mixed distributions - a combination of perpendicularly peaked distributions and beamlike distributions ( cigar distribution), and at the end of each of three episodes always evolved into a beamlike or field-aligned distribution. This evolution pattern seen at a relative fixed observing ( satellite) location usually developed within the locally observed dipolarization time scale. We have interpreted this pattern to indicate that electrons were coming from different regions along the magnetotail and have gotten accelerated differently. This has led us to suggest and present a model in which Fermi acceleration dominates for electrons that are accelerated from the reconnection region, while betatron acceleration dominates for electrons that are accelerated from the midtail region that is very close to the satellite location.

TI The anisotropic hard-sphere crystal-melt interfacial free energy from fluctuations SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID DENSITY-FUNCTIONAL THEORY; FLUID INTERFACE; SURFACE; NUCLEATION; SOLIDIFICATION; SIMULATION; COLLOIDS; SYSTEMS AB We have calculated the interfacial free energy for the hard-sphere system, as a function of crystal interface orientation, using a method that examines the fluctuations in the height of the interface during molecular dynamics simulations. The approach is particularly sensitive for the anisotropy of the interfacial free energy. We find an average interfacial free energy of gamma=0.56 +/- 0.02k(B)T sigma(-2). This value is lower than earlier results based upon direct calculations of the free energy [R. L. Davidchack and B. B. Laird, Phys. Rev. Lett. 85, 4751 (2000)]. However, both the average value and the anisotropy agree with the recent values obtained by extrapolation from direct calculations for a series of the inverse-power potentials [R. L.

XAFS spectra were acquired at the Ca K edge at temperatures up to 400 degrees C and pressures up to 350 bars. For the system at 400 degrees C, both Ca (4038.5 eV) and Cl (2822.4 eV) K-edge data were acquired and a global model was used to fit the two independent sets of XAFS data. Measurements were made at the bending magnet beamline (sector 20) at the Advanced Photon Source, Argonne. Above 250 degrees C, a significant number of Ca2+-Cl- direct contact ion pairs form in agreement with existing thermodynamic data for this system. For a 1 m CaCl2 solution at 400 degrees C, the mean coordination structure about Ca2+ contains 3.2 +/- 0.6 water molecules at an average Ca-O distance of 2.356 +/- 0.026 A and 1.8 +/- 0.7 Cl- at a Ca-Cl distance of 2.677 +/- 0.007 A. An evaluation of the Ca and Cl preedge and near-edge (x-ray absorption structure) spectra provided further confirmation of the change in the Ca2+ first-shell structure and symmetry. Overall these measurements provide a structural basis for understanding solvation of Ca2+ in hydrothermal systems. These results also provide important new insights into the structural aspects of Ca2+ ion pairing that are the basis of many biological processes under ambient conditions.

The doping via N-2(+) ion bombardment leads to the implantation of N atoms (similar to 5% saturation concentration) that coexist with O vacancies. Ti 2p core level spectra show the formation of Ti3+ and a second partially reduced Ti species with oxidation states between +4 and +3. The valence region of the TiO2-xNy(110) systems exhibits a broad peak for Ti3+ near the Fermi level and N-induced features above the O 2p valence band that shift the edge up by similar to 0.5 eV. The magnitude of this shift is consistent with the "redshift" observed in the ultraviolet spectrum of N-doped TiO2. The experimental and theoretical results show the existence of attractive interactions between the dopant and O vacancies. First, the presence of N embedded in the surface layer reduces the formation energy of O vacancies. Second, the existence of O vacancies stabilizes the N impurities with respect to N-2(g) formation. When oxygen vacancies and N impurities are together there is an electron transfer from the higher energy 3d band of Ti3+ to the lower energy 2p band of the N2- impurities.

TI Polarizable contributions to the surface tension of liquid water SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID MOLECULAR-DYNAMICS SIMULATIONS; EQUILIBRIUM SIMULATIONS; VAPOR INTERFACE; THERMODYNAMICS; SYSTEMS; MODEL AB Surface tension, gamma, strongly affects interfacial properties in fluids. The degree to which polarizability affects gamma in water is thus far not well established. To address this situation, we carry out molecular dynamics simulations to study the interfacial forces acting on a slab of liquid water surrounded by vacuum using the Gaussian charge polarizable (GCP) model at 298.15 K. The GCP model incorporates both a fixed dipole due to Gaussian distributed charges and a polarizable dipole. We find a well-defined bulklike region forms with a width of approximate to 31 A. The average density of the bulklike region agrees with the experimental value of 0.997 g/cm(3). However, we find that the orientation of the molecules in the bulklike region is strongly influenced by the interfaces, even at a distance five molecular diameters from the interface. Specifically, the orientations of both the permanent and induced dipoles show a preferred orientation parallel to the interface. Near the interface, the preferred orientation of the dipoles becomes more pronounced and the average magnitude of the induced dipoles decreases monotonically. To quantify the degree to which molecular orientation affects gamma, we calculate the contributions to gamma from permanent dipolar interactions, induced dipolar interactions, and dispersion forces. We find that the induced dipole interactions and the permanent dipole interactions, as well as the cross interactions, have positive contributions to gamma, and therefore contribute stability to the interface. The repulsive core interactions result in a negative contribution to gamma, which nearly cancels the positive contributions from the dipoles. The large negative core contributions to gamma are the result of small oxygen-oxygen separation between molecules. These small separations occur due to the strong attractions between hydrogen and oxygen atoms. The final predicted value for gamma (68.65 mN/m) shows a deviation of approximate to 4% of the experimental value of 71.972 mN/m. The inclusion of polarization is critical for this model to produce an accurate value. (c) 2006 American Institute of Physics. C1 Wesleyan Univ, Dept Phys, Middletown, CT 06459 USA.

Substrate Hg fluxes were measured using field chamber methods at thermal and nonthermal sites. The highest Hg fluxes ( up to 541 ng m(-2) h(-1)) were measured at thermal active areas. Fluxes from altered and unaltered nonthermal sites were < 10 ng m(-2) h(-1) and were comparable to those measured in natural low-Hg background regions for YC and DV, and at LVC they were slightly elevated. Similarly, reactive gaseous mercury concentrations were higher in thermal active areas. Using a Geographic Information System framework for scaling, estimated area-average Hg emissions from substrates were 0.9 - 3.8 ng m(-2) h(-1) at LVC, 0.8 - 2.8 ng m(-2) h(-1) at YC, and 0.4 - 0.5 ng m(-2) h(-1) at DV. At LVC, nonthermal areas were the primary substrate source of atmospheric Hg (> 98%). At YC, substrate Hg emissions were dominated ( 50 to 90%) by acidically altered thermal areas. Substrate emissions at DV were low and primarily from nonthermal areas (66% to 75%). Fumarole emissions at LVC ( 91 - 146 kg yr(-1)) and YC (0.18 - 1.6 kg yr(-1) for Mud Volcano) were estimated by applying Hg: H2O and Hg: CO2 ratios in hydrothermal gas samples to H2O and CO2 emissions. Applying total area-average emissions from substrates and thermal features at LVC, YC, and DV to similar systems across the conterminous United States, yearly atmospheric Hg emissions from active hydrothermal systems are projected to be 1.3 - 2.1 Mg.

TI Structure, vibrational spectrum, and ring puckering barrier of cyclobutane SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID HIGHER-DERIVATIVE METHODS; DOUBLE-MINIMUM VIBRATION; ROTATION INTERACTION; TRIMETHYLENE OXIDE; POTENTIAL FUNCTION; INFRARED-SPECTROSCOPY; POLYATOMIC-MOLECULES; MICROWAVE SPECTRUM; LARGE-AMPLITUDE; WAVE-FUNCTIONS AB We present the results of high level ab initio calculations for the structure, harmonic and anharmonic spectroscopic constants, and ring puckering barrier of cyclobutane (C4H8) in an effort to establish the minimum theoretical requirements needed for their accurate description. We have found that accurate estimates for the barrier between the minimum (D-2d) and transition state (D-4h) configurations require both higher levels of electron correlation [MP4, CCSD(T)] and orbital basis sets of quadruple-zeta quality or larger. By performing CCSD( T) calculations with basis sets as large as cc-pV5Z, we were able to obtain, for the first time, a value for the puckering barrier that lies within 10 cm(-1) ( or 2%) from experiment, whereas the best previously calculated values were in errors exceeding 40% of experiment. Our best estimate of 498 cm-1 for the puckering barrier is within 10 cm-1 of the experimental value proposed originally, but it lies similar to 50 cm-1 higher than the revisited value, which was obtained more recently using different assumptions regarding the coupling between the various modes. It is therefore suggested that revisiting the analysis of the experimental data might be warranted. Our best computed values (at the CCSD(T)/aug-cc-pVTZ level of theory) for the equilibrium structural parameters of C4H8 are r(C- C) = 1.554 angstrom, r(C- H-alpha) = 1.093 angstrom, r(C-H-beta) = 1.091 angstrom, phi(C- C- C) = 88.1 degrees, alpha(H-alpha-C-H-beta) = 109.15 degrees, and theta = 29.68 degrees for the puckering angle. We have found that the puckering angle theta is more sensitive to the level of electron correlation than to the size of the basis set for a given method. We furthermore present anharmonic calculations that are based on a second-order perturbative evaluation of rovibrational parameters and their effects on the vibrational spectra and average structure. We have found that the anharmonic calculations predict the experimentally measured fundamental band origins within 1% (<= 30 cm(-1)) for most vibrations. The results of the current study can serve as a guide for future calculations on the substituted four-member ring hydrocarbon compounds. To this end we present a method for estimating the puckering barrier height at higher levels of electron correlation [MP4, CCSD( T)] from the MP2 results that can be used in chemically similar compounds.

It is found that, at lower temperatures, higher loadings are more stable, whereas at higher temperatures, lower loadings are more stable. Attractive forces between the guest and host molecules lead to a stabilized minimum-energy configuration at low temperatures. At higher temperatures, greater displacements take the system away from the shallow energy minimum, and the trend reverses. The nature of the cavity structure is nearly spherical for a loading of one, leads to preferential occupation near the hydroxyl ring crowns of the cavity with a loading of two, and at higher loadings, leads to occupation of the interstitial sites ( the hydroxyl rings) between cages by a single H-2 molecule with the remaining molecules occupying the equatorial plane of the cavity. Occupation of the interstitial positions of the cavities leads to facile diffusion. C1 Pacific NW Natl Lab, Richland, WA 99352 USA. Univ Wisconsin Parkside, Kenosha, WI 53141 USA.

TI Labeled gold nanoparticles immobilized at smooth metallic substrates: Systematic investigation of surface plasmon resonance and surface-enhanced Raman scattering SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID NANOSPHERE LITHOGRAPHY; SILVER NANOPARTICLES; PERIODIC ARRAY; LOCAL-FIELDS; SPECTROSCOPY; IMMUNOASSAY; AG; EXTINCTION; MICROSCOPY; MOLECULES AB This paper experimentally and theoretically investigates the influence of an underlying metallic substrate (i. e., gold and silver) on the surface plasmon resonance (SPR) of labeled gold nanoparticles and the concomitant impact on the surface-enhanced Raman scattering (SERS) signal from the labels. These experiments employ nanoparticles of varied sizes (30-100 nm) that are coated with a bifunctional Raman scatterer composed of (1) a disulfide for chemisorption to the nanoparticle surface, (2) a succinimidyl ester for formation of a covalent linkage to an amine-terminated self-assembled monolayer on the underlying substrate, and (3) an aryl nitro group with an intrinsically strong Raman active vibrational mode. This approach allows facile systematic assessments of how variations in nanoparticle size, substrate composition, and the gap between the nanoparticle and substrate affect the SPR of the bound particles. Both UV-vis transmission and reflection absorption (incident angle of 58 degrees) spectroscopy are used to characterize the effect of each of these parameters on SPR. These results are then correlated with SERS enhancement factors (EFs) that were determined by accounting for particle surface concentrations, which were measured by atomic force microscopy, and the absolute number of labels, which were calculated on the basis of the surface area of each of the different-sized particles. All SERS spectra were collected at an incident angle of 58 degrees with respect to the surface normal. As expected, the SPR for particles in solution red-shifts with increasing particle size. More importantly, the SPR moves to even longer wavelengths as the size of immobilized particles increases and as the gap between the immobilized particle and substrate decreases. The red shift is also greater for a gold nanoparticle tethered to a gold substrate compared to a silver substrate. A theoretical model for the extinction of a particle above a flat substrate, corrected for surface scattering, radiation damping, and dynamic depolarization, is also briefly detailed. SPR results calculated with the model are consistent with the shifts observed in the SPR position for each of the manipulated experimental variables. The largest EFs are found for samples with an SPR maximum (lambda(max)) between the wavelengths for laser excitation (633 nm) and the Raman band for the symmetric nitro stretch of the particle coating (690 nm). As an example, an order of magnitude in the SERS enhancement factor is gained for a 60-nm particle immobilized 1.2 nm above a gold substrate (SPR lambda(max) = 657 nm) compared to that for a 30-nm particle (SPR lambda(max) = 596 nm).

Of several different types of fuel cells under development today, polymer electrolyte fuel cells (PEFCs) have been recognized as a potential future power source for zero-emission vehicles(4,5). However, to become commercially viable, PEFCs have to overcome the barrier of high catalyst cost caused by the exclusive use of platinum and platinum-based catalysts(6-8) in the fuel-cell electrodes. Here we demonstrate a new class of low-cost (non-precious metal)/(heteroatomic polymer) nanocomposite catalysts for the PEFC cathode, capable of combining high oxygen-reduction activity with good performance durability. Without any optimization, the cobalt-polypyrrole composite catalyst enables power densities of about 0.15 W cm(-2) in H-2-O-2 fuel cells and displays no signs of performance degradation for more than 100 hours. The results of this study show that heteroatomic polymers can be used not only to stabilize the non-precious metal in the acidic environment of the PEFC cathode but also to generate active sites for oxygen reduction reaction.

This low-lying negative parity state is consistent with a narrower shell gap for exotic nuclei with Z << N and N approximate to 20. Monte Carlo shell-model calculations with the modem SDPF-M interaction successfully describe neutron-rich nuclei in the vicinity of N = 20 where normal and intruder configurations coexist at low excitation energy. This observation demonstrates the importance of direct reactions for the study of exotic nuclei and the predictive power of these large-scale shell-model calculations. (c) 2006 Elsevier B.V.

An attempt is being made to improve the thermal properties of nanocomposites by synthesizing imidazolium salts from 2-methyl imidazole and ion exchanging the salts with clay minerals. This study focuses on the role of the chemistry of imidazolium salt(s) used in functionalizing clay and processing conditions in the formulation of epoxy nanocomposites. The nanodispersion of clay in an epoxy matrix is evaluated qualitatively by X-ray diffraction (XRD), transmission electronic microscopy (TEM), and laser scanning confocal microscopy (LSCM). We demonstrate the use of LCSM for quantitative image analysis and to study the dispersion of clay layers, tagged with a fluorescent dye in the epoxy matrix. XRD and TEM results reveal that the hand mixed nanocomposite has tactoid morphology, while ultrasonicated organoclay (without hydroxyl group) epoxy nanocomposite exhibits a mixed morphology, and an ultrasonicated organoclay (with hydroxyl group) epoxy nanocomposite had well dispersed clay distribution in the epoxy matrix. Results from the three complimentary techniques enable the characterization of the clay platelets over several length scales ranging from the micrometer to the nanometer scale. (c) 2006 Elsevier Ltd.

More than two thirds of the faults studied display diagenetic minerals virtually absent from adjacent protolith. Stable isotope analyses indicate that smectite enrichment and calcite cementation result from low-temperature meteoric fluid-fault interaction. Fault zone microstructures, rare earth element signatures, and mineralogy indicate that smectite was introduced to deformation band fault zones by a combination of translocation from the surface and in situ alteration of fault gouge. Rod-shaped calcite microcrystallites and the close association of calcite with plant roots suggest a combination of pedogenic, biologically mediated, and physicochemical precipitation. Enrichment in smectite and calcite modified major oxide and trace element contents of deformation bands with respect to protolith. Collectively, these observations indicate that these faults have served as, and may still be, zones of preferential vadose zone fluid flow and transport. These processes alter fault rock permeability; affect the transport of solutes via processes such as dissolution, precipitation, and adsorption, and they change the mechanical properties of the fault zone. Smectite and calcite enrichment results in localization of deformation, effectively halting the further development of deformation bands. Vadose zone alteration therefore is one way to produce a clay-rich fault core at early stages in a fault's history, resulting in fault zone weakening and localization of slip. Progressive burial of growth faults can subsequently bring fault cores into the seismogenic zone. C1 Univ Texas, Dept Geol Sci, Austin, TX 78712 USA.

TI Understanding the role of Ti in reversible hydrogen storage as sodium alanate: A combined experimental and density functional theoretical approach SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID ALUMINUM-HYDRIDE; AL(111); ALH3; ADSORPTION; SURFACES; 1ST-PRINCIPLES; DECOMPOSITION; SPECTROSCOPY; MOLECULES; NAALH4 AB We report the results of an experimental and theoretical study of hydrogen storage in sodium alanate (NaAlH4). Reversible hydrogen storage in this material is dependent on the presence of 2-4% Ti dopant. Our combined study shows that the role of Ti may be linked entirely to Ti-containing active catalytic sites in the metallic Al phase present in the dehydrogenated NaAlH4. The EXAFS data presented here show that dehydrogenated samples contain a highly disordered distribution of Ti-Al distances with no long-range order beyond the second coordination sphere. We have used density functional theory techniques to calculate the chemical potential of possible Ti arrangements on an Al(001) surface for Ti coverages ranging from 0.125 to 0.5 monolayer (ML) and have identified those that can chemisorb molecular hydrogen via spontaneous or only moderately activated pathways. The chemisorption process exhibits a characteristic nodal symmetry property for the low-barrier sites: the incipient doped surface-H-2 adduct's highest occupied molecular orbital (HOMO) incorporates the sigma* antibonding molecular orbital of hydrogen, allowing the transfer of charge density from the surface to dissociate the molecular hydrogen. This work also proposes a plausible mechanism for the transport of an aluminum hydride species back into the NaH lattice that is supported by Car-Parrinello molecular dynamics (CPMD) simulations of the stability and mobility of aluminum clusters (alanes) on Al(001). As an experimental validation of the proposed role of titanium and the subsequent diffusion of alanes, we demonstrate experimentally that AlH3 reacts with NaH to form NaAlH4 without any requirement of a catalyst or hydrogen overpressure.

We report on a simple and environmentally friendly route involving oxidation in air to selectively remove sp(2)-bonded carbon from ND. Thermogravimetric analysis and in situ Raman spectroscopy shows that sp(2) and sp(3) carbon species oxidize with different rates at 375-450 degrees C and reveals a narrow temperature range of 400-430 degrees C in which the oxidation of sp2-bonded carbon occurs with no or minimal loss of diamond. X-ray absorption near-edge structure spectroscopy detects an increase of up to 2 orders of magnitude in the sp(3)/sp(2) ratio after oxidation. The content of up to 96% of sp(3)-bonded carbon in the oxidized samples is comparable to that found in microcrystalline diamond and is unprecedented for ND powders. Transmission electron microscopy and Fourier transform infrared spectroscopy studies show high purity 5-nm ND particles covered by oxygen-containing surface functional groups. The surface functionalization can be controlled by subsequent treatments ( e. g., hydrogenization). In contrast to current purification techniques, the air oxidation process does not require the use of toxic or aggressive chemicals, catalysts, or inhibitors and opens avenues for numerous new applications of nanodiamond.

TI Space weather drivers in the ACE era SO SPACE WEATHER-THE INTERNATIONAL JOURNAL OF RESEARCH AND APPLICATIONS LA English DT Article ID HEAVY-IONS; STORM; SYSTEM AB We examine ACE observations of interplanetary disturbances and energetic particle activity for the period of solar maximum during solar cycle 23 and compare these measurements to the historical record as represented by the National Space Science Data Center Omnitape of near-Earth observations. Magnetospheric response parameters, Dst and Kp, are similarly compared for the two epochs. We find that ACE observed an unexpectedly large number of the strongest transient events with the strength of magnetospheric drivers exceeding the historical record for the space flight era. This is not entirely true of the magnetospheric response, which demonstrates that the magnetospheric response is an integrated effect that is more subtle than examination of single hourly averages would indicate. For these and other reasons, we argue that satellites at L1 orbit, such as ACE, provide an excellent database for the study of magnetospheric storm drivers and their associated energetic particle populations from which space weather models may be refined. We also compare and contrast energetic particle measurements. While protons are a large space weather concern, heavy ions are also a radiation hazard for hardware in particular. We argue that heavy ion radiation predictions based on the measurements of protons are not reliable and that only by measuring the actual composition of the solar energetic particle population can we hope to understand and address the threat posed by these particles to machines and to obtain a more complete view of the radiation environment.

TI 3D hexagonal (R-3m) mesostructured nanocrystalline titania thin films: Synthesis and characterization SO ADVANCED FUNCTIONAL MATERIALS LA English DT Article ID MESOPOROUS MOLECULAR-SIEVES; SENSITIZED SOLAR-CELLS; X-RAY-SCATTERING; TIO2 FILMS; STRUCTURAL-ANALYSIS; TRIBLOCK COPOLYMER; METHYLENE-BLUE; ANATASE; SILICA; SYSTEMS AB A straightforward and reproducible synthesis of crack-free large-area thin films of 3D hexagonal (R-3m) mesostructured nanocrystalline titania (meso-nc-TiO2) using a Pluronic triblock copolymer (P123)/1-butanol templating system is described. The characterization of the films is achieved using a combination of electron microscopy (high-resolution scanning electron microscopy and scanning transmission electron microscopy), grazing-incidence small-angle X-ray scattering, in situ high-temperature X-ray diffraction, and variable-angle spectroscopic ellipsometry. The mesostructure of the obtained films is found to be based upon a 3D periodic array of large elliptically shaped cages with diameters around 20 nm interconnected by windows of about 5 nm in size. The mesopores of the film calcined at 300 degrees C are very highly ordered, and the titania framework of the film has a crystallinity of 40% being composed of 5.8 nm sized anatase crystallites. The film displays high thermal stability in that the collapse of the pore architecture is incomplete even at 600 degrees C. The accessible surface area of 3D hexagonal meso-nc-TiO2 estimated by the absorption of methylene blue is nearly twice as large as that of 2D hexagonal meso-nc-TiO2 at the same annealing temperature.

Bulk nanostructured materials usually have high strength, but disappointingly low ductility. All previous attempts to enhance the ductility of nanostructured materials have sacrificed their yield strengths. This strategy is applicable to many nanostructured alloys and composites.

TI Evaluation of the effects of various culture conditions on Cr(VI) reduction by Shewanella oneidensis MR-1 in a novel high-throughput mini-bioreactor SO BIOTECHNOLOGY AND BIOENGINEERING LA English DT Article DE pH; temperature; dissolved oxygen; chromium reduction; high-throughput cultivation ID BIOPROCESS DESIGN HTBD; HEXAVALENT CHROMIUM; GROWTH; MICROBIOREACTOR; PUTREFACIENS; MEMBRANE; GENOME AB The growth and Cr(VI) reduction by Shewanella oneidensis MR-1 was examined using a mini-bioreactor system that independently monitors and controls pH dissolved oxygen (DO), and temperature for each of its 24: 10-mL reactors. Independent monitoring and control of each reactor in the cassette allows the exploration of a matrix of environmental conditions known to influence S. oneidensis chromium reduction. S. oneidensis MR-1 grew in minimal medium without amino acid or vitamin supplementation under aerobic conditions but required serine and glycine supplementation under anaerobic conditions. Growth was inhibited by DO concentrations > 80%. Lactate transformation to acetate was enhanced by low concentration of DO during the logarithmic growth phase. Between 11 and 35 degrees C, the growth rate obeyed the Arrhenius reaction rate-temperature relationship, with a maximum growth rate occurring at 35 degrees C. S. oneidensis MR-1 was able to grow over a wide range of pH (6-9). At neutral pH and temperatures ranging from 30 to 35 degrees C, S. oneidensis MR-1 reduced 100 mu M Cr(VI) to Cr(III) within 20 min in the exponential growth phase, and the growth rate was not affected by the addition of chromate; it reduced chromate even faster at temperatures between 35 and 39 degrees C. At low temperatures (< 25 degrees C), acidic (pH < 6.5), or alkaline (pH > 8.5) conditions, 100 mu M Cr(VI) strongly inhibited growth and chromate reduction. The mini-bioreactor system enabled the rapid determination of these parameters reproducibly and easily by performing very few experiments. Besides its use for examining parameters of interest to environmental remediation, the device will also allow one to quickly assess parameters for optimal production of recombinant proteins or secondary metabolites.

TI RNA: protein ratio of the unicellular organism as a characteristic of phosphorous and nitrogen stoichiometry and of the cellular requirement of ribosomes for protein synthesis SO BMC BIOLOGY LA English DT Article ID ESCHERICHIA-COLI; GROWTH-RATE; N-P; TERRESTRIAL PLANTS; BACILLUS-SUBTILIS; MODULATION FACTOR; RIBONUCLEIC-ACID; TRANSCRIPTION; STRESS; GENES AB Background: Mean phosphorous: nitrogen (P:N) ratios and relationships of P: N ratios with the growth rate of organisms indicate a surprising similarity among and within microbial species, plants, and insect herbivores. To reveal the cellular mechanisms underling this similarity, the macromolecular composition of seven microorganisms and the effect of specific growth rate (SGR) on RNA: protein ratio, the number of ribosomes, and peptide elongation rate (PER) were analyzed under different conditions of exponential growth. Results: It was found that P: N ratios calculated from RNA and protein contents in these particular organisms were in the same range as the mean ratios reported for diverse organisms and had similar positive relationships with growth rate, consistent with the growth-rate hypothesis. The efficiency of protein synthesis in microorganisms is estimated as the number of active ribosomes required for the incorporation of one amino acid into the synthesized protein. This parameter is calculated as the SGR: PER ratio. Experimental and theoretical evidence indicated that the requirement of ribosomes for protein synthesis is proportional to the RNA: protein ratio. The constant of proportionality had the same values for all organisms, and was derived mechanistically from the characteristics of the protein-synthesis machinery of the cell (the number of nucleotides per ribosome, the average masses of nucleotides and amino acids, the fraction of ribosomal RNA in the total RNA, and the fraction of active ribosomes). Impairment of the growth conditions decreased the RNA: protein ratio and increased the overall efficiency of protein synthesis in the microorganisms. Conclusion: Our results suggest that the decrease in RNA: protein and estimated P: N ratios with decrease in the growth rate of the microorganism is a consequence of an increased overall efficiency of protein synthesis in the cell resulting from activation of the general stress response and increased transcription of cellular maintenance genes at the expense of growth related genes. The strong link between P: N stoichiometry, RNA: protein ratio, ribosomal requirement for protein synthesis, and growth rate of microorganisms indicated by the study could be used to characterize the N and P economy of complex ecosystems such as soils and the oceans.

The surfaces were functionalized with 2,2'-bipyridine, 4-(dimethylamino)pyridine, and pentafluorobenzene. The C-13 and Si-29 NMR spectra of these materials showed that the structures and concentrations of these functional groups remained unaffected by the heat treatment. Furthermore, it has been demonstrated that the surfactant template, cetyltrimethylammonium bromide ( CTAB), could be effectively removed from these materials by heat treatment without disrupting the covalent bonds between the functional groups and the silica surface. The chemical accessibility and reactivity of the organic functionalities were also preserved after heating. C1 Iowa State Univ, US Dept Energy, Ames Lab, Ames, IA 50011 USA.

This initial success triggered the development of our own high surface area hypercrosslinked materials.

TI Bias-dependent electron spin lifetimes in n-GaAs and the role of donor impact ionization SO APPLIED PHYSICS LETTERS LA English DT Article ID GALLIUM-ARSENIDE; TRANSPORT AB In bulk n-GaAs epilayers doped near the metal-insulator transition, the authors study the evolution of electron spin lifetime tau(s) as a function of applied lateral electrical bias E-x. tau(s) is measured via the Hanle effect using magneto-optical Kerr rotation. At low temperatures (T < 10 K, where electrons are partially localized and tau(s)> 100 ns at zero bias), a marked collapse of tau(s) is observed when E-x exceeds the donor impact ionization threshold at similar to 10 V/cm. A steep increase in the concentration of warm delocalized electrons-subject to Dyakonov-Perel spin relaxation [Sov. Phys. Solid State 13, 3023 (1972)]-accounts for the rapid collapse of tau(s) and strongly influences electron spin transport in this regime. (c) 2006 American Institute of Physics.

TI Bulk heterojunction organic photovoltaic devices based on phenyl-cored thiophene dendrimers SO APPLIED PHYSICS LETTERS LA English DT Article ID PLASTIC SOLAR-CELLS; MOLECULAR-WEIGHT; PERFORMANCE; MORPHOLOGY; BLENDS AB Bulk heterojunction organic photovoltaic devices have been fabricated by blending phenyl-cored thiophene dendrimers with a fullerene derivative. A power conversion efficiency of 1.3% under simulated AM1.5 illumination is obtained for a four-arm dendrimer, despite its large optical band gap of 2.1 eV. The devices exhibit an increase in short-circuit current and power conversion efficiency as the length of the arm is increased. The fill factors of the devices studied are characteristically low, which is attributed to overly uniform mixing of the blend. (c) 2006 American Institute of Physics.

The PLD grown films show the typical luminescence resulting from the Ce3+ 5d-4f transition. Maximum luminescence efficiency was observed for films prepared at an oxygen partial pressure of 200 mTorr at 600 degrees C. These conditions reflect a balance between Ce4+/Ce3+ interconversion and the crystalline quality of the films. The results indicate that PLD offers a low temperature deposition technique for complex oxide phosphor materials. (c) 2006 American Institute of Physics.

Using Rutherford backscattering, scanning electron microscopy, and atomic force microscopy, they found that the depth of blisters coincided with that of maximum implantation damage. A model based on experimental results is presented showing the effect of tensile strain on the local diffusion of vacancies toward the depth of maximum damage, which promotes the nucleation and growth of platelets and ultimately blisters.

TI Resonant Raman scattering with the E+ band in a dilute GaAs1-xNx alloy (x=0.1%) SO APPLIED PHYSICS LETTERS LA English DT Article ID TRANSITIONS; STATES AB Resonant Raman scattering has been applied to a dilute GaAs1-xNx alloy with 0.1% N. The Raman lines of GaAs and GaN related modes, their combinations, and multiple order replicas of GaAs-like longitudinal-optical modes have been observed with a lower N composition than those studied previously. All these Raman features are found to be strongly enhanced with excitations in resonance with a broad photoluminescence band that is associated with the so-called E+ transition. This study provides additional insights into how the GaAs host conduction band states are perturbed and thus the electron-phonon interaction is affected by the N doping.

The direct-bonded interconnect between subcells of this two-junction cell enables monolithic interconnection without threading dislocations and planar defects that typically arise during lattice-mismatched epitaxial heterostructure growth. The bonded interface is a metal-free n(+)GaAs/n(+)InP tunnel junction. The tandem cell open-circuit voltage is approximately the sum of the subcell open-circuit voltages. The internal quantum efficiency is 0.8 for the GaAs subcell compared to 0.9 for an unbonded GaAs subcell near the band gap energy and is 0.7 for both of the InGaAs subcell and an unbonded InGaAs subcell, with bonded and unbonded subcells similar in spectral response.

The target heterometallic analogue to uranyl has now been prepared by direct laser desorption/ionization of a U/Ir alloy, and by oxidation of UIr(+) with N(2)O and C(2)H(4)O. Properties of UIr(+), UPt(+), and UAu(+) bimetallic ions have been studied. They demonstrate direct actinide-transition metal bonding, and support the concept of "autogenic isolobality".

The structures of the three compounds have been established using single-crystal X-ray diffraction: alpha-Sm3Ge5 crystallizes with its own type in the hexagonal space group P6h2c ( No. 190) with cell parameters a = 6.9238(11) A, c = 8.491(3) A, and Z = 2, whereas beta-Sm3Ge5 adopts the face-centered orthorhombic Y3Ge5 type with space group Fdd2 (No. 43) and with cell parameters a = 5.8281(6) A, b = 17.476-(2) A, c = 13.785(2) A, and Z = 8. The orthorhombic Gd3Ge5 with cell parameters a = 5.784(2) A, b = 17.355(6) A, and c = 13.785(5)A is isostructural with beta-Sm3Ge5. The structures of the title compounds can be described as AIB(2) and alpha-ThSi2 derivatives with long-range ordering of the germanium vacancies. Temperature-dependent DC magnetization (5-300 K) measurements show evidence of antiferromagnetic ordering below ca. 30 and 10 K for alpha-Sm3Ge5 and beta-Sm3Ge5, respectively. Gd3Ge5 undergoes two successive magnetic transitions below ca. 15 and 11 K. The temperature dependence of the resistivity and heat capacity of Gd3Ge5 are discussed as well.

Oxidation of U-0 by PhEEPh yields monomeric seven-coordinate U(EPh)(4)(py)(3) (E = S(1), Se(2)). The dimeric eight-coordinate complexes [U(EPh)(2)(mu(2)-EPh)(2)(CH3CN)(2)](2) (E = S(3), Se(4)) are obtained by crystallization from solutions of 1 and 2 dissolved in acetonitrile. Oxidation of U-0 by pySSpy and crystallization from thf yields nine-coordinate U(Spy)(4)(thf) (5). Incorporation of elemental selenium into the oxidation of U-0 by PhSeSePh results in the isolation of [U(py)(2)(SePh)(mu(3)- Se)(mu(2)-SePh)](4)center dot 4py (6), a tetrameric cluster in which each U(IV) ion is eight-coordinate and the U4Se4 core forms a distorted cube. The compounds were analyzed spectroscopically and the single-crystal X-ray structures of 1 and 3-6 were determined. The isolation of 1-6 represents six new examples of actinide chalcogenolates and allows insight into the nature of "hard" actinide ion-"soft" chalcogen donor interactions.

The precursor films were deposited in a migration-enhanced molecular beam epitaxial reactor on Mo-coated thin glass substrates. During the selenization, the formation of CuSe was observed, followed by its transformation to CuSe2 at higher temperature. The formation of alpha-CuInSe2 was initiated at a temperature between 250 and 300 degrees C. Additionally, the production of MoSe2 was clearly detected at temperatures above 440 degrees C. The reaction kinetics were analyzed using both the Avrami and parabolic rate models to estimate diffusion-limited activation energies of 124 (+/- 19) and 100 (+/- 14) kJ/mol, respectively.

We focus specifically on the effect of these corrections on the vacuum configuration of scalar fields in softly-broken supersymmetric theories and the role these corrections play in generating nondiagonal soft scalar masses. Both effects can only be properly studied when the divergences are regulated in a manifestly supersymmetfic manner-something which has thus far been neglected in past treatments. We show how a supersymmetric regularization can impact past conclusions about both types of phenomena and discuss what types of high-energy theories are likely to be safe from unwanted flavor-changing neutral current interactions in the context of supergravity theories derived from heterotic string compactifications.

TI Natural fracture distributions in sinuous, channel-fill sandstones of the Cedar Mountain Formation, Utah SO AAPG BULLETIN LA English DT Article AB A set of regional natural fractures, present in the sandy to conglomeratic, fluvial, channel-fill deposits' of the Cedar Mountain Formation (east-central Utah) has a consistent west-northwest strike regardless of the local axial orientations of the sinuous channels. The fracture-producing stresses were not significantly refracted by the mechanical-property contrast between the channel-fill sandstones and the encasing overbank mudstones. In addition, fracture spacing along the sinuous channel axes is relatively constant between one-half and one-third of the bed thickness for both large fractures that cut the full thickness of the channel deposits and for smaller fractures in the thinner, component beds. Fracture spacing was apparently not affected by the variations in stress amplification that commonly result from differently oriented stiff inclusions in a ductile matrix. Therefore, in the absence of other structures, fracture intensity and the orientation of fracture-related maximum horizontal permeability in sinuous elongated reservoirs will be relatively constant regardless of the orientation of the long axis of the reservoir. Whether maximum permeability trends along, oblique, or across such reservoirs, and the relative drainage efficiency of horizontal versus vertical wellbores drilled into them, will vary only with the local trend of the channel axis.

The main feature of the proposed framework is the use of several programming paradigms for the different implementation layers, with a strong emphasis on object-oriented classes and operator overloading for the top layer, and optimized FORTRAN and C code for the layers underneath. We describe an implementation of the proposed framework that is based on the ML library, the algebraic multilevel preconditioning package of Trilinos, which supports state-of-the-art parallel smoothed aggregation methods, and can be used to define general algebraic and geometric multilevel and multigrid preconditioners and solvers. The article demonstrates that we can take advantage of object-oriented programming and operator overloading to obtain intuitive, easy-to-read, and easy-to-develop codes that are at the same time efficient and scalable. Several numerical experiments obtained on serial and parallel computers show that the overhead required by the object-oriented layer is very modest, therefore allowing developers to focus on the new algorithms they are developing and testing, rather than on implementation details.

TI Algorithm 856: APPSPACK 4.0: Asynchronous parallel pattern search for derivative-free optimization SO ACM TRANSACTIONS ON MATHEMATICAL SOFTWARE LA English DT Article DE algorithms; design; documentation; parallel derivative-free optimization; pattern search ID CONVERGENCE AB APPSPACK is software for solving unconstrained and bound-constrained optimization problems. It implements an asynchronous parallel pattern search method that has been specifically designed for problems characterized by expensive function evaluations. Using APPSPACK to solve optimization problems has several advantages: No derivative information is needed; the procedure for evaluating the objective function can be executed via a separate program or script; the code can be run serially or in parallel, regardless of whether the function evaluation itself is parallel; and the software is freely available. We describe the underlying algorithm, data structures, and features of APPSPACK version 4.0, as well as how to use and customize the software. C1 Sandia Natl Labs, Livermore, CA 94551 USA.

TI On a viscoplastic model for rocks with mechanism-dependent characteristic times SO ACTA GEOTECHNICA LA English DT Article DE Plasticity; Viscoplasticity; Strain-rate sensitivity; Rock mechanics; Geomechanics; Kolsky bar; Shock loading AB This paper summarizes the results of a theoretical and experimental program at Sandia National Laboratories aimed at identifying and modeling key physical features of rocks and rock-like materials at the laboratory scale over a broad range of strain rates. The mathematical development of a constitutive model is discussed and model predictions versus experimental data are given for a suite of laboratory tests. Concurrent pore collapse and cracking at the microscale are seen as competitive micromechanisms that give rise to the well-known macroscale phenomenon of a transition from volumetric compaction to dilatation under quasistatic triaxial compression. For high-rate loading, this competition between pore collapse and microcracking also seems to account for recently identified differences in strain-rate sensitivity between uniaxial-strain "plate slap" data compared to uniaxial-stress Kolsky bar data. A description is given of how this work supports ongoing efforts to develop a predictive capability in simulating deformation and failure of natural geological materials, including those that contain structural features such as joints and other spatial heterogeneities.

Two different specimens were prepared with the purpose of separating the effects of frictional heating and severe plastic deformation on the changes of the preferred orientation in the as-received rolled plates: a plate processed with both stirring pin and tool shoulder, i.e., a regular FSP plate subjected to both severe plastic deformation and frictional heating (Case 1); and a plate processed only with the tool shoulder, i.e., subjected mainly to frictional heating (Case 2). The diffraction peak intensities provide insights into the texture variations at various locations across the centerline and through the thickness of the FSP plates. Comparison of the texture variations between Cases I and 2 clearly shows that the severe plastic deformation from the stirring pin affects the preferred orientation during the FSP, while heating alone from the tool shoulder has little effect.

TI Nucleation and growth of the alpha ' martensitic phase in Pu-Ga alloys SO ACTA MATERIALIA LA English DT Article DE phase transformations; martensitic phase transformation; nucleation of phase transformations ID DIVORCED EUTECTOID TRANSFORMATION; RADIATION-ENHANCED DIFFUSION; PLUTONIUM ALLOYS; STABILITY; KINETICS AB In a Pu-2.0 at.% Ga alloy, it is observed experimentally that the amount of the martensitic alpha' product formed upon cooling the metastable 5 phase below the martensite burst temperature (M-b) is a function of the holding temperature and holding time of a prior conditioning ("annealing") treatment. Before subjecting a sample to a cooling and heating cycle to form and revert the alpha' phase, it was first homogenized for 8 h at 375 degrees C to remove any microstructural memory of prior transformations. Subsequently, conditioning was carried out in a differential scanning calorimeter apparatus at temperatures in the range between -50 and 370 degrees C for periods of up to 70 h to determine the holding time and temperature that produced the largest volume fraction of alpha' upon subsequent cooling. Using transformation peak areas (i.e., the heats of transformation) as a measure of the amount of alpha' formed, the largest amount of alpha' was obtained following holding at 25 degrees C for at least 6 h. Additional time at 25 degrees C up to 70 h, did not increase the amount of subsequent a' formation. At 25 degrees C, the Pu-2.0 at.% Ga alloy is below the eutectoid transformation temperature in the phase diagram and the expected equilibrium phases are alpha and PU3Ga, although a complete cutectoid decomposition of 8 to these phases is expected to be extremely slow. It is proposed here that the influence of the conditioning treatment can be attributed to the activation of alpha-phase embryos in the matrix as a beginning step toward the eutectoid decomposition, and we discuss the effects of spontaneous self-irradiation accompanying the Pu radioactive decay on the activation process. Subsequently, upon cooling, certain embryos appear to be active as sites for the burst growth of martensitic alpha' particles, and their amount, distribution, and potency appear to contribute to the total amount of martensitic product formed. A modeling approach based on classic nucleation theory is presented to describe the formation of alpha-phase embryos during conditioning. The reasons why the holding times during conditioning become eventually ineffective in promoting more alpha' formation on cooling are discussed in terms of the differences in the potency of the embryos created in the 6 matrix during conditioning and in terms of growth-impeding volume strains in the matrix resulting from an increasing number of martensite particles, thus opposing further growth. It is suggested that the disparate amounts of the alpha' formation reported in the literature following various studies may be in part a consequence of the fact that conditioning times at ambient temperatures are inevitably involved in any handling of radioactive samples prior to testing.

TI Residual stress measurements in a thick, dissimilar aluminum alloy friction stir weld SO ACTA MATERIALIA LA English DT Article DE residual stresses; friction stir welding; neutron diffraction; aluminium alloys ID CONTOUR METHOD; BUTT JOINTS; MICROSTRUCTURE; FATIGUE; STRAINS; STEEL; HEAT AB Plates (25.4 mm thick) of aluminum alloys 7050-T7451 and 2024-T351 were joined in a butt joint by friction stir welding (FSW). A 54 mm long test specimen was removed from the parent plate, and cross-sectional maps of residual stresses were measured using neutron diffraction and the contour method. The stresses in the test specimen peaked at only about 32 MPa and had the conventional "M" profile with tensile stress peaks in the heat-affected zone outside the weld. The asymmetric stress distribution is discussed relative to the FSW process and the regions of highest thermal gradients. The general agreement between the two measurement techniques validated the ability of each technique to measure the low-magnitude stresses, less than 0.05% of the elastic modulus. Subtle differences between the two were attributed to spatial variations in the unstressed lattice spacing (d(0)) and also intergranular strains affecting the neutron results. The FSW stresses prior to relaxation from removal of the test specimen were estimated to have been about 43 MPa, demonstrating the ability of FSW to produce low-stress welds in even fairly thick sections. To avoid the estimated 25% stress relaxation from removing the test specimen, the specimen would have had to be quite long because the St. Venant's characteristic distance in this case was more related to the transverse dimensions of the specimen than to the plate thickness.

Laser annealing was used to induce several levels of film stress ranging from -1.7 GPa (compressive) to +2.4 GPa (tensile). Indentations into the films generated radial cracks that extended into channel cracks with increasing indentation depth. Crack length was a function of both the indentation load and the sign and magnitude of the residual film stress, with tensile stresses promoting crack extension. Indentation fracture toughness models were used to estimate the fracture toughness of the ta-C films. Results obtained using an acoustic sensor embedded into the nanoindentation tip revealed a relationship between the released acoustic energy and the total crack length. These results were used to formulate an expression for the fracture toughness of the thin films directly from the acoustic signal, with comparable results to the standard indentation-based measurement.

However, recent molecular dynamics (MID) simulations of GB migration in bicrystals have suggested that, in pure materials, GB diffusion and GB migration involve distinct mechanisms and, hence, different activation barriers. Here we report MID simulations of grain growth in an impurity-free model nanocrystalline palladium microstructure containing only high-energy GBs. By contrast with the bicrystal simulations, we observe virtually identical activation energies for grain growth and GB diffusion. We discuss several mechanisms that might be responsible for this difference between the bicrystal and polycrystal results, including accommodation of the curvature-driven GB migration by the elimination of GB area and GB excess free volume and a possible finite mobility of the triple junctions. The qualitative agreement of our observations with the general experimental findings is remarkable given the absence of any impurities in our model system. This suggests that a fundamental, intrinsic process may be responsible for the similar activation energies for GB migration and GB diffusion in polycrystals. In our model system this process seems to involve the accommodation of the curvature-driven GB migration by GB diffusion to eliminate the GB area and related GB free volume at the triple junctions.

Among the six intermetallic compounds in this system, the formation enthalpies of Al9Ir2, Al3Ir and AlIr were obtained from T = 0 K first-principles total energy calculations. The formation enthalpies of Al45Ir13, Al13Ir4 and Al2.7Ir, whose structures are either unknown or too complicated for first-principles calculations, were estimated using a greedy algorithm developed in this study. The mixing enthalpies of Al1-xIrx, face-centered cubic (fcc) alloys were calculated at x = 0.25, 0.5 and 0.75 using the special quasirandom structure approach. The vibrational formation entropy of AlIr was also calculated using the supercell method within the harmonic and quasi-harmonic approximation, respectively. We demonstrated that, with the incorporation of first-principles energetics, a physically meaningful thermodynamic description of the Al-Ir system can be obtained even with very scarce experimental data. The predicted B2 and fee two-phase equilibrium in the Al-Ir-Ni ternary system was also in reasonable agreement with experiments. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd.

Traditional hardening laws cannot accurately model these phenomena. In this paper, an anisotropic model that captures the influence of evolving texture on the plastic response of hcp metals is proposed. Initial yielding is described using a recently developed analytical yield function that accounts for both anisotropy and strength differential effects. To describe the change of the shape of the yield surface during monotonic loading, the evolution of the anisotropic coefficients involved in the expression of the yield function is considered. The evolution laws for the anisotropic coefficients are obtained based on experimental data and crystal plasticity theory, together with a macroscopic-scale interpolation technique. This approach is further applied to the description of the mechanical behavior of high-purity zirconium at room temperature. Validation of the proposed model is provided by applying it to the simulation of the three-dimensional deformation of a beam subjected to four-point bending along different directions with respect to the hard-to-deform < c >-axis predominant orientation of the material. Comparison between predicted and measured macroscopic strain fields and beam sections shows that the proposed model describes very well the difference in response between the tensile and compressive fibers and the shift of the neutral axis.

The analysis is limited to two-dimensional laminar flows. In the Section after the Introduction, a brief review of the single particle approach is provided; it is then shown that in most multiphase flow problems some generalization of these forces acting on a single particle is used. We then describe a different way of defining the lift force and the drag force, an approach used in non-Newtonian fluid mechanics. In the following Section, the essential equations of Mixture Theory are provided and the specific approach of [1] is used. In this scheme, the lift force is part of the interaction mechanisms, which are to be modeled as constitutive parameters. In the final Section, we derive an expression for the lift force, whereby it is shown that the normal component of the force acting on the body, obtained by integrating the traction vector of the mixture acting on a single isolated particle, will give us the desired expression for the lift force in multi-component flows.

The process begins by making a porous preform, open pores of which are filled with the foam material. Thereafter the preform is removed, generally by shaking or by dissolution, leaving an interconnected porous network within the foam material. We give here a general description of the process and its variants. We then give a brief overview of its fundamentals, placing particular focus on pathways it offers for microstructural tailoring and control.

Geometric properties of foams and foam cells are analyzed. A simple, accurate theory relates the total suface area of foam to the cell-size distribution. The total surface area is approximately equal to the total edge length when both quantities are scaled by average cell volume. Voronoi structures are significantly different from foams, which raises questions over their use for predicting structure-property relationships.

We developed a method to predict the permeability tensor from particle shape and packing structure. Digital geometry maps were created for the pore space in regular cubic and random packs of particles with various aspect ratios using a numerical packing algorithm. The lattice-Boltzmann method was used to simulate saturated flow through these packs, and the effect of particle shape and degree of alignment on the permeability tensor was characterized. Results show that the degree of anisotropy in permeability depends not only upon particle shape and alignment, but also on the three-dimensional structure of the pack. In random packs, more oblate particles and higher degrees of particle alignment lead to reduced permeability perpendicular to the direction of particle alignment compared to the direction parallel to particle alignment.

The apparently healthy father produced abnormally high frequencies of disomic sperm for each of the four chromosomes involved in the trisomic pregnancies (P < 0.003, by sperm fluorescence in situ hybridization (FISH)). His elevated sperm aneuploidies persisted over a 2-year period and affected all chromosomes evaluated, suggesting that he had a genome-wide defect in meiotic disjunction. He also had the highest frequencies of aneuploid sperm reported for any healthy man to date. His frequencies of aneuploid sperm were comparable to the peak frequencies of the transient responses reported in some cancer patients after receiving aneugenic chemotherapies. These findings indicate that apparently healthy men can produce abnormally high frequencies of sperm aneuploidies that suggest that this condition may contribute to recurrent trisomic pregnancies.

TI Marbled salamanders (Ambystoma opacum) choose low elevation nest sites when cover availability is controlled SO AMPHIBIA-REPTILIA LA English DT Article ID OVIPOSITION SITE; SEX DETERMINATION; EVOLUTION; CHOICE; SELECTION; SURVIVAL AB Nest site selection is an important part of adult reproductive behavior because growth and survival of young are often affected by the local environment. In terrestrially nesting marbled salamanders, nest elevation is likely important to reproductive success because it is directly related to the time of hatching. We tested the hypothesis that females choose nest sites based on elevation and its correlates by controlling the availability of nesting cover, a potentially important factor in nest site selection which often covaries with elevation. Breeding adults were confined to field enclosures in which natural nesting cover had been removed and replaced with equal proportions of artificial cover in each of three elevation zones. In four enclosures that spanned from lowest to highest areas of a wetland breeding site, females used artificial nesting cover most frequently at low elevations. These results contrast with other studies in which intermediate elevations had highest nest densities, but are consistent with a conceptual model in which opposing selective forces result in locally adapted nest site selection.

The imprinted beads were intended as a front-end spore capture/concentration stage of an integrated biological detection system. Our approach involved embedding bead surfaces with Bacillus thuringiensis kurstaki (Bt) spores (as a surrogate for Bacillus anthracis) during synthesis. Subsequent steps involved lithographic deactivation using a perfluoroether; spore removal to create imprint sites; and coating imprints with the lectin, concanavalin A, to provide general affinity. The synthesis of the intended material with the desired imprints was verified by scanning electron and confocal laser-scanning microscopy. The material was evaluated using spore-binding assays with either Bt or Bacillus subtilis (Bs) spores. The binding assays indicated strong spore-binding capability and a robust imprinting effect that accounted for 25% additional binding over non-imprinted controls. The binding assay results also indicated that further refinement of the surface deactivation procedure would enhance the performance of the imprinted substrate.

Members of the genus Dehalococcoides are apparently solely responsible for dechlorination beyond DCE, but isolates of Dehalococcoides each metabolize only a subset of PCE dechlorination intermediates and the interactions among distinct Dehalococcoides strains that result in complete dechlorination are not well understood. Here we apply quantitative PCR to 16S rRNA and reductase gene sequences to discriminate and track Dehalococcoides strains in a TCE enrichment derived from soil taken from the Alameda Naval Air Station (ANAS) using a four-gene plasmid standard. This standard increased experimental accuracy such that 16S rRNA and summed reductase gene copy numbers matched to within 10%. The ANAS culture was found to contain only a single Dehalococcoides 16S rRNA gene sequence, matching that of D. ethenogenes 195, but both the vcrA and tceA reductive dehalogenase genes. Quantities of these two genes in the enrichment summed to the quantity of the Dehalococcoides 16S rRNA gene. Further, between ANAS subcultures enriched on TCE, cDCE, or VC, the relative copy number of the two dehalogenases shifted 14-fold, indicating that the genes are present in two different Dehalococcoides strains. Comparison of cell yields in VC-, cDCE-, and TCE-enriched subcultures suggests that the tceA-containing strain is responsible for nearly all of the TCE and cDCE metabolism in ANAS, whereas the vcrA-containing strain is responsible for all of the VC metabolism.

When Dehalococcoides ethenogenes 195 was provided with trichloroethene (TCE) as the electron acceptor, the expression of the tceA gene increased by 90-fold relative to that in cells starved of chlorinated ethenes, demonstrating that tceA gene expression is indicative of the active physiological state of this strain. In a Dehalococcoides-containing enrichment culture that contains both the tceA and vcrA genes, the tceA gene was up-regulated in response to TCE and cis-1,2-dichloroethene (cDCE) exposure, while the vcrA gene was upregulated in response to TCE, cDCE, and vinyl chloride (VC). When chlorinated ethenes were depleted, the RDase-encoding gene transcripts decayed exponentially, with a half-life between 4.8 and 6.1 h, until they reached a stable background level after 2 days. We found that while gene expression correlated generally to the presence of chlorinated ethenes, there was no apparent direct relationship between RDase-encoding transcript numbers and respective rates of TCE, cDCE, and VC dechlorination activities. However, elevated tceA and vcrA expression did correlate with chlorinated-ethene reduction beyond cDCE, suggesting that elevated RDase-encoding transcript numbers could serve as a biomarker for the physiological ability of Dehalococcoides spp. to dechlorinate beyond cDCE.

TI Application of a high-density oligonucleotide microarray approach to study bacterial population dynamics during uranium reduction and reoxidation SO APPLIED AND ENVIRONMENTAL MICROBIOLOGY LA English DT Article ID 16S RIBOSOMAL-RNA; DISSIMILATORY METAL REDUCTION; CONTAMINATED AQUIFER; MICROBIAL-POPULATIONS; SUBSURFACE SEDIMENTS; COMMUNITY STRUCTURE; FRAPPIERI TCE1; PCR; BIAS; NITRATE AB Reduction of soluble uranium U(VI) to less-soluble uranium U(M is a promising approach to minimize migration from contaminated aquifers. It is generally assumed. that, under constant reducing conditions, U(M is stable and immobile; however, in a previous study, we documented reoxidation of U(IV) under continuous reducing conditions (Wan et al., Environ. Sci. Technol. 2005, 39:6162-6169). To determine if changes in microbial community composition were a factor in U(IV) reoxidation, we employed a high-density phylogenetic DNA microarray (16S microarray) containing 500,000 probes to monitor changes in bacterial populations during this remediation process. Comparison of the 16S microarray with clone libraries demonstrated successful detection and classification of most clone groups. Analysis of the most dynamic groups of 16S rRNA gene amplicons detected by the 16S microarray identified five clusters of bacterial subfamilies responding in a similar manner. This approach demonstrated that amplicons of known metal-reducing bacteria such as Geothrix fermentans (confirmed by quantitative PCR) and those within the Geobacteraceae were abundant during U(VI) reduction and did not decline during the U(IV) reoxidation phase. Significantly, it appears that the observed reoxidation of uranium under reducing conditions occurred despite elevated microbial activity and the consistent presence of metal-reducing bacteria. High-density phylogenetic microarrays constitute a powerful tool, enabling the detection and monitoring of a substantial portion of the microbial population in a routine, accurate, and reproducible manner.

Sequencing and annotation of the genome revealed a single circular chromosome (3,481,691 bp; G+C content of 50.4%) and a plasmid (40,420 bp) that contain 3,052 and 41 candidate protein-encoding genes, respectively. The genes encoding proteins necessary for the function of known modes of lithotrophy and autotrophy were identified. Contrary to betaproteobacterial nitrifier genomes, the N. oceani genome contained two complete rrn operons. In contrast, only one copy of the genes needed to synthesize functional ammonia monooxygenase and hydroxyl-amine oxidoreductase, as well as the proteins that relay the extracted electrons to a terminal electron acceptor, were identified. The N. oceani genome contained genes for 13 complete two-component systems. The genome also contained all the genes needed to reconstruct complete central pathways, the tricarboxylic acid cycle, and the Embden-Meyerhof-Parnass and pentose phosphate pathways. The N. oceani genome contains the genes required to store and utilize energy from glycogen inclusion bodies and sucrose. Polyphosphate and pyrophosphate appear to be integrated in this bacterium's energy metabolism, stress tolerance, and ability to assimilate carbon via gluconeogenesis. One set of genes for type I ribulose-1,5-bisphosphate carboxylase/oxygenase was identified, while genes necessary for methanotrophy and for carboxysome formation were not identified. The N. oceani genome contains two copies each of the genes or operons necessary to assemble functional complexes I and IV as well as ATP synthase (one H+-dependent F0F1 type, one Na+-dependent V type).

Cells challenged aerobically with an initial chromate concentration of 0.3 mM in complex growth medium were compared to untreated control cells grown in the absence of chromate. At the 24-h time point at which cells were harvested for transcriptome and proteome analyses, no residual Cr(VI) was detected in the culture supernatant, thus suggesting the complete uptake and/or reduction of this metal by cells. In contrast to the untreated control cells, Cr(VI)-exposed cells formed apparently aseptate, nonmotille filaments that tended to aggregate. Transcriptome profiling and mass spectrometry-based proteomic characterization revealed that the principal molecular response to 24-h Cr(VI) exposure was the induction of prophage-related genes and their encoded products as well as a number of functionally undefined hypothetical genes that were located within the integrated phage regions of the MR-1 genome. In addition, genes with annotated functions in DNA metabolism, cell division, biosynthesis and degradation of the murein (peptidoglycan) sacculus, membrane response, and general environmental stress protection were upregulated, while genes encoding chemotaxis, motility, and transport/binding proteins were largely repressed under conditions of 24-h chromate treatment.

TI Catalytic partial oxidation of n-tetradecane in the presence of sulfur or polynuclear aromatics: Effects of support and metal SO APPLIED CATALYSIS A-GENERAL LA English DT Article DE fuel reforming; catalytic partial oxidation; logistic fuels; carbon formation; sulfur resistance; oxygen-ion conductivity ID SYNTHESIS GAS; HYDROGEN-PRODUCTION; HIGHER HYDROCARBONS; DIESEL FUEL; HIGH YIELDS; METHANE; PLATINUM; REACTORS; SYSTEM; DECANE AB Catalytic partial oxidation (CPOX) of liquid fuels is an attractive option for producing a hydrogen-rich gas stream for fuel cell applications. However, the high-sulfur and aromatic content present in these fuels increases the propensity towards deactivation of noble metal-based catalysts used in this reaction. The relationship between catalyst supports and deactivation has been studied here for three catalysts (Rh/Ce0.56Zr0.44O2-x, Pt/ Ce0.56Zr0.44O2-x and Pt/Al2O3) in a fixed-bed catalytic reactor using various mixtures of n-tetradecane with 1-methylnaphthalene or dibenzothiophene to simulate logistic fuels. Carbon deposition during CPOX reforming was shown to be directly related to the concentration of unsaturated products formed. Unsaturates (olefins + aromatics), which are known coke precursors, were observed on both platinum catalysts during CPOX of n-tetradecane with no sulfur (particularly from Pt/Al2O3), but not on Rh/Ce0.56Zr0.44O2-x. For the Rh/Ce0.56Zr0.44O2-x, yields of hydrogen and carbon monoxide dropped to a stationary level after the introduction of sulfur-containing feed (1000 ppm sulfur) or aromatic-containing feed (5 wt%), however, the catalyst activity was restored after removing the sulfur or aromatics from the feed. For the platinum catalysts, hydrogen and carbon monoxide yields dropped continuously over time in the presence of sulfur or aromatics in feed. The superior performance of Rh/Ce0.56Zr0.44O2-x can be attributed to the higher oxygen-ion conductivity of the Ce0.56Zr0.44O2-x support as well as the higher activity of rhodium compared to platinum.

Sulfur removal was found to be greater at 150 degrees C than at lower temperatures for Cu(II)Y adsorbents containing as the secondary cation either Na+ (CuNaY) or H+ (CuHY). Capacities on the order of 60 ml gasoline/g adsorbent were obtained with both materials before the sulfur concentration in the effluent exceeded 3 ppmw. Overall, the CuHY zeolite showed somewhat better desulfurization performance. It is proposed that acid sites (W) that are present play a role in the desulfurization process, facilitating chemical reactions involving the sulfur-containing molecules. This leads to the generation of sulfur-bearing compounds having molecular weights and sizes greater than those present in the initial feed. Some of these heavier sulfur species are eluted but many do not elute. The net effect is a desulfurization pathway that is the result of entrapment of sulfur-containing molecules in addition to a desulfurization pathway involving direct interaction between the copper and sulfur atoms.

The catalysts were characterized for activity by microreactor tests and temperature-programmed reduction (TPR), and for physical properties by surface area measurements, CO chemisorption, X-ray diffraction (XRD), and extended X-ray absorption fine structure (EXAFS) analyses. The order of activity for ATR of isobutane was Rh/La-Al2O3 > Rh/Y-ZrO2 > Rh/GdCeO2 > Rh/gamma-Al2O3 > Rh/CaAl12O19, which paralleled the ranking of the catalysts based on the dispersion and reducibility of Rh, with Rh/La-Al2O3 having the highest dispersion and the lowest reduction temperature. After subjecting the catalysts to an accelerated ageing process, the activity for ATR of isobutane was similar for all catalysts except for Rh/Gd-CeO2, which experienced a significant loss in steam reforming activity. Rhodium dispersion measurements confirmed that the ageing process had caused Rh to sinter on all of the supports. A major conclusion from this study is that the primary effect of the support was on the dispersion of Rh. (C) 2006 Elsevier B.V. All rights reserved.

TI Novel aspects of the physical chemistry of CO/SiO2 Fischer-Tropsch catalyst preparations - The chemistry of cobalt silicate formation during catalyst preparation or hydrogenation SO APPLIED CATALYSIS A-GENERAL LA English DT Article DE Fischer-Tropsch; cobalt; silica; cobalt silicate ID CALCIUM HYDROXIDE; HYDROUS OXIDES; TEMPERATURE AB Co/SiO2 catalysts were prepared by both impregnation and precipitation techniques and analyzed by IR, TPR, XRD, and BET methods at intermediate stages of their preparation to define the stage and mechanism of cobalt silicate formation. To prove that reducing conditions can lead to cobalt silicate, one part of a catalyst prepared by impregnation of silica with cobalt nitrate was calcined in air at 350 degrees C, and another part in H2N2 atmosphere at the same temperature. Infrared spectra revealed the presence of Co-O-Si absorption in the sample exposed to reducing atmosphere. Cobalt silicate formation is postulated to be a reaction between migrating silicic acid and hydrated cobalt hydroxide generated in the reduction process. Precipitation of cobalt nitrate solution at 80-90 degrees C with potassium hydroxide solution in the presence of Davison 952 silica resulted in amorphous cobalt silicate formation. Precipitation with sodium carbonate solution gave no IR-detectable quantities of cobalt silicate in the presence of Davison 952 silica, but cobalt silicate was detected when Cab-O-Sil HS-5 silica was used. Precipitations of Co and Mg nitrates (similar to 2:1 Co/Mg ratio) with sodium carbonate gave essentially quantitative yield of amorphous cobalt silicates whether the precipitation occurred in the presence of Davison 952 silica, or the silica was added after the precipitation. Cobalt silicate formation during precipitation either by KOH or Na2CO3 solutions is a heretofore unrecognized facile reaction of hydrated cobalt hydroxide with silicic acid (dissolved silica). The mechanism which can explain Co(OH)(2)(H2O)(x) formation during Na2CO3 precipitations is an acid-base reaction between hydrated Co ions and carbonate ions. This reaction also yields carbonic acid, which competes with silicic acid for Co(OH)(2)(H2O)(x) in secondary reactions. (C) 2006 Elsevier B.V. All rights reserved.

TI Boundary-element simulation of hydrodynamic interaction of two smooth spheres suspended in an unbounded Couette flow SO APPLIED ENERGY LA English DT Article DE hydrodynamic interaction; boundary-element method; wide-gap Couette flow; non-linear shear field; particle migration ID LOW-REYNOLDS-NUMBER; LINEAR SHEAR FIELD; SPHERICAL-PARTICLES; SELF-DIFFUSION; MULTIPARTICLE SYSTEMS; SUSPENSIONS; MOTION; RESISTANCE; SEDIMENTATION; DISPERSION AB The hydrodynamic interaction between two particles, suspended in shear flows, is fundamental to the macroscopic characterization of suspension flows. Although the understanding of the hydrodynamic interaction between two particles suspended in a quiescent or linear shear flow is mature, studies of the interaction in a non-linear shear field are rare. The current study calculates such interactions between two neutrally-buoyant smooth spheres moving at negligible Reynolds numbers in an unbounded wide-gap Couette flow by three-dimensional boundary-element method (BEM) simulations. Both the identical sphere-pair and the disparate sphere-pair are considered. The numerical results show that there is a preferential cross-streamline migration of the center-of-gravity of the sphere-pair in the plane of shear in the unbounded wide-gap Couette flow that does not arise in simple shear-flow. This migration is always directed towards low-shear regions when the sphere having the larger translational velocity approaches the other sphere, and reverses towards high-shear regions when the faster sphere leads the other sphere in the plane of shear. There is also a cross-streamline migration of the center-of-gravity of the sphere-pair in the plane of vorticity, but this migration does not have a preferential direction. These migrations are symmetric about the point where the spheres are at the minimum separation, and are only significant when the hydrodynamic interaction of the spheres is sufficiently strong. These results show that the migration of the center-of-gravity of the sphere-pair can be attributed to the non-linearity of the shear field. The hydrodynamic interaction between the two spheres has been quantified under various conditions by the BEM simulations for both identical and disparate spheres. (c) 2005 Elsevier Ltd.

TI Electrical properties and diffusion behavior of hafnium in single crystal silicon SO APPLIED PHYSICS A-MATERIALS SCIENCE & PROCESSING LA English DT Article ID CONCERTED-EXCHANGE MECHANISM; GATE DIELECTRICS; DEFECTS; INTERSTITIALS; OXIDATION; VACANCIES; FILMS; GOLD AB Electrical properties and diffusivity of Hf in single crystal Si have been studied. Several deep level defects were found for Hf in both the upper and lower half of the silicon band gap, and their parameters were measured. Energy levels, concentrations, and capture cross sections were determined for all Hf defects. The DLTS spectra depend on the cooling rate. Analysis of electrical properties yielded a dominant deep level defect at E-C -0.27 eV, which showed field enhanced emission due to Poole-Frenkel effect, confirming its donor nature. This agreed with results obtained using CV and TSCAP. In the lower half of the bandgap, a defect level at E-V +0.24 eV was found to have a capture barrier of 0.04 eV. Diffusivity of Hf was studied using two methods for Hf incorporation in Si - ion implantation and sputtering. Analysis of broadening of the Hf profile in implanted samples, which were annealed for 168 h, allowed us to estimate the diffusivity of Hf as 1.7x10(-15) cm(2)/s at 1250 degrees C: the spreading of implanted profiles at lower temperatures was too small. Analysis of Hf depth profiles in the sputtered and annealed samples reveals that Hf appears to have a fast and slow component to its diffusivity whose migration energy was determined to be 3.5 +/- 0.3 eV and 4.1 +/- 0.3 eV respectively. The fast and slow component are ascribed to interstitial and substitutional Hf with an energy level of E-C -0.27 eV and E-V +0.43 eV respectively. The mechanism for the fast component seems to indicate a direct interstitial diffusion mechanism whereas the diffusion of the substitutional Hf seems most consistent with the concerted exchange diffusion mechanism. In addition, estimates of solubility for both, interstitial and substitutional Hf, are included. C1 Univ Calif Berkeley, Dept Mat Sci & Engn, Berkeley, CA 94720 USA.

Carbon atom fluorescence at 248 nm and the Na D-line at 589 nm are used as signatures of soot and NaCl, respectively. Soot particles are encapsulated with a NaCl layer in a well-controlled inverted flame burner. NaCl particles are injected into the methane-air co-flow flame to coat the soot particles. ArF laser irradiation of the coated particles in an air stream at 1.14 J/cm(2) produces fluorescence from Na, C, and CH. At 0.69 J/cm(2), which is slightly above the fluorescence threshold, but not enough for considerable fragmentation of the particles, Na D-line persists with little carbon and no CH observed. These results suggest that the photolytic fragmentation-fluorescence using 193 nm excitation can be effectively used for in situ, real-time chemical analysis of core-shell nanoparticles.

Compared to conventional surface-enhanced Raman scattering from nanometric gold colloid particles, HERS exhibits higher strength gain, exceptional reproducibility, simple and reliable substrate preparation, and excellent mechanical stability. By correlating the hole density with Raman scattering gain, we determined optimum HERS gain for 50 nm diameter holes at similar to 100 holes/mu m(2). Providing a Raman substrate with uniform "hot spots", we expect that HERS will make the quantitative Raman analysis of biological molecules possible.

TI High levels of dopamine D-2 receptors in unaffected members of alcoholic families - Possible protective factors SO ARCHIVES OF GENERAL PSYCHIATRY LA English DT Article ID BRAIN METABOLIC-RESPONSE; D2 RECEPTORS; BINDING CHARACTERISTICS; NUCLEUS-ACCUMBENS; D-2 RECEPTORS; IN-VIVO; DEPENDENCE; HUMANS; RATS; PET AB Context: Predisposition to alcoholism is likely an interaction between genetic and environmental factors that confer vulnerability and protection. Alcoholic subjects have low levels of dopamine D-2 receptors in striatum, and increasing D-2 receptor levels in laboratory animals reduces alcohol consumption. Objectives: To test whether high levels of D-2 receptors may be protective against alcoholism and whether this is mediated by their modulation of activity in orbitofrontal cortex and cingulate gyrus (regions involved in salience attribution, emotional reactivity, and inhibitory control). Design: Research (nonalcoholic subjects with a family history of alcoholism) and comparison (nonalcoholic subjects with a negative family history) sample. Setting: Outpatient setting. Participants: Fifteen nonalcoholic subjects who had an alcoholic father and at least 2 other first- or second-degree relatives who were alcoholics (family-positive group) and 16 nonalcoholic controls with no family history of alcoholism (family-negative group). Main Outcome Measures: Results of positron emission tomography with raclopride C 11 to assess D-2 receptors and with fludeoxyglucose F 18 to assess brain glucose metabolism (marker of brain function). Personality measures were obtained with the Multidimensional Personality Questionnaire. Results: Availability of D2 receptors was significantly higher in caudate and ventral striatum in family-positive than family-negative subjects. In family-positive but not family-negative subjects, striatal D-2 receptors were associated with metabolism in anterior cingulate (Brodmann area 24/25) and orbitofrontal (Brodmann area 11) and prefrontal (Brodmann area 9/10) cortices, and with personality scores of positive emotionality. Conclusions: The higher-than-normal D-2 receptor availability in nonalcoholic members of alcoholic families supports the hypothesis that high levels of D-2 receptors may protect against alcoholism. The significant associations between D-2 receptors and metabolism in frontal regions involved with emotional reactivity and executive control suggest that high levels of D-2 receptors could protect against alcoholism by regulating circuits involved in inhibiting behavioral responses and in controlling emotions.

TI Short-term treatment of cocaine and/or methamphetamine abuse with vigabatrin - Ocular safety pilot results SO ARCHIVES OF OPHTHALMOLOGY LA English DT Article ID VISUAL-FIELD DEFECTS; GAMMA-VINYL GABA; DRUG-WITHDRAWAL; CONSTRICTION; ADDICTION; TOXICITY; CONTINUE; HISTORY AB Objective: To evaluate the ocular safety of short-term use of vigabatrin to treat cocaine and/ or methamphetamine addiction. Methods: Individuals who were actively using cocaine and/ or methamphetamine were eligible for enrollment. Enrolled subjects were scheduled for comprehensive eye examinations at the beginning and end of the study. Visual field testing was performed at baseline and 1 week, 4 weeks, 8 weeks, and 1 month or more after discontinuing vigabatrin. Twenty-eight subjects received at least 1 dose of vigabatrin; however, only 20 subjects continued beyond the initial escalating vigabatrin dose phase to the treatment phase. Of these 20 subjects, 18 completed the study with full follow- up. Visual fields were evaluated subjectively by 2 glaucoma specialists and analyzed objectively for group and individual changes in quadrant mean sensitivity. The objective analysis was also repeated for superior field quadrants after excluding the uppermost peripheral points tominimize the eyelid effect. The main outcome measures were change of visual field, visual acuity, and ocular adverse effects. Results: Vigabatrin seemed to help treat cocaine and/ or methamphetamine addiction. Of 18 subjects, 16 had negative test results for cocaine and methamphetamine use during the last 6 weeks of the trial. No ocular adverse events were detected. The subjective evaluation did not reveal visual field constriction in any of the 18 evaluable participants. Objective group and individual analyses for quadrantmean sensitivity did not show any change from baseline in any quadrant. No changes in visual acuity were noted. Conclusions: In this short- term pilot study, vigabatrin seemed to help treat cocaine and/ or methamphetamine abuse. There was no evidence of ocular or visual field adverse effects.

TI Simulating the hallmarks of Cancer SO ARTIFICIAL LIFE LA English DT Article DE Cancer; agent simulation; cellular automata ID DIFFERENTIAL-EQUATION MODEL; TUMOR-GROWTH; MUTATIONS; CELLS; INSTABILITY; SELECTION AB Cancer can be viewed as the loss of cooperative cell behaviors that normally facilitate multicellularity; including the formation of tissues and organs. Hanahan and Weinberg describe the phenotypic differences between healthy and cancerous cells in an article titled "The Hallmarks of Cancer" (Cell, 100, 57-70, 2000). Here the authors propose six phenotypic changes at the cellular level as the essential hallmarks of cancer. They investigate the dynamics and interactions of these hallmarks in a model known as CancerSim. They describe how CancerSim implements the hallmarks in an agent-based simulation which can help test the hypotheses put forth by Hanahan and Weinberg. Experiments with CancerSim are described that study the interactions of cell phenotype alterations, and in particular, the likely sequences of precancerous mutations, known as pathways. The experiments show that sequencing is an important factor in tumorigenesis, as some mutations have preconditions-they are selectively advantageous only in combination with other mutations. CancerSim enables a modeler to Study the dynamics of a developing tumor and simulate how progression can be altered by tuning model parameters. C1 Sandia Natl Labs, Albuquerque, NM 87185 USA.

We initially identified 1197 RRab (RR0) candidate stars brighter than the ROTSE median magnitude V = 14. Periods, amplitudes, and mean V magnitudes are determined for a subset of 1188 RRab stars with well-defined light curves. Metallicities are determined for 589 stars by the Fourier parameter method and by the relationship between period, amplitude, and [Fe/H]. We comment on the difficulties of clearly classifying RRc (RR1) variables in the NSVS data set. Distances to the RRab stars are calculated using an adopted luminosity-metallicity relation with corrections for interstellar extinction. The 589 RRab stars in our final sample are used to study the properties of the RRab population within 5 kpc of the Sun. The Bailey diagram of period versus amplitude shows that the largest component of this sample belongs to Oosterhoff type I. Metal-rich ([Fe/H] > -1) RRab stars appear to be associated with the Galactic disk. Our metal-rich RRab sample may include a thin-disk, as well as a thick-disk population, although the uncertainties are too large to establish this. There is some evidence among the metal-rich RRab stars for a decline in scale height with increasing [Fe/H], as was found by Layden. The distribution of RRab stars with -1 < [Fe/H] < -1.25 indicates that within this metallicity range the RRab stars are a mixture of stars belonging to halo and disk populations.

TI Panchromatic study of GRB 060124: from precursor to afterglow SO ASTRONOMY & ASTROPHYSICS LA English DT Article DE gamma rays : bursts; X-rays : bursts; X-rays : individuals : GRB 060124 ID GAMMA-RAY BURST; OPTICAL FLASH; REVERSE SHOCK; LIGHT CURVES; BATSE OBSERVATIONS; ENGINE ACTIVITY; GRB 990123; EMISSION; SPECTRA; TELESCOPE AB We present observations of GRB 060124, the first event for which both the prompt and the afterglow emission could be observed simultaneously and in their entirety by the three Swift instruments. Indeed, Swift-BAT triggered on a precursor similar to 570 s before the main burst peak, and this allowed Swift to repoint the narrow field instruments to the burst position similar to 350 s before the main burst occurred. GRB 060124 also triggered Konus-Wind, which observed the prompt emission in a harder gamma-ray band (up to 2 MeV). Thanks to these exceptional circumstances, the temporal and spectral properties of the prompt emission can be studied in the optical, X-ray and gamma-ray ranges. While the X-ray emission (0.2-10 keV) clearly tracks the gamma-ray burst, the optical component follows a different pattern, likely indicating a different origin, possibly the onset of external shocks. The prompt GRB spectrum shows significant spectral evolution, with both the peak energy and the spectral index varying. As observed in several long GRBs, significant lags are measured between the hard-and low-energy components, showing that this behaviour extends over 3 decades in energy. The GRB peaks are also much broader at soft energies. This is related to the temporal evolution of the spectrum, and can be accounted for by assuming that the electron spectral index softened with time. The burst energy (E-iso similar to 5 x 10(53) erg) and average peak energy (E-p similar to 300 keV) make GRB 060124 consistent with the Amati relation. The X-ray afterglow is characterized by a decay which presents a break at t(b) similar to 10(5) s. C1 Osserv Astron Brera, INAF, Merate, LC, Italy. Univ Milan, I-20126 Milan, Italy.

TI Redshift and shear calibration: Impact on cosmic shear studies and survey design SO ASTROPARTICLE PHYSICS LA English DT Article DE gravitational lensing; galaxy clusters; cosmology; statistics ID HUBBLE DEEP FIELD; STIS PURE PARALLELS; POWER SPECTRUM; SPACE-TELESCOPE; TOMOGRAPHY; STATISTICS; COSMOLOGY; UNIVERSE AB The cosmological interpretation of weak lensing by large-scale structures requires knowledge of the redshift distribution of the source galaxies. Current lensing surveys are often calibrated using external redshift samples which span a significantly smaller sky area in comparison to the lensing survey, and are thus subject to sample variance. Some future lensing surveys are expected to be calibrated in the same way, in particular the fainter galaxy populations where the entire color coverage, and hence photometric redshift estimate, could be challenging to obtain. With N-body simulations, we study the impact of this sample variance on cosmic shear analysis and show that, to first approximation, it behaves like a shear calibration error I e. Using the Hubble Deep Field as a redshift calibration survey could therefore be a problem for current lensing surveys. We discuss the impact of the redshift distribution sampling error and a shear calibration error on the design of future lensing surveys, and find that a lensing survey of area 0 square degrees and limiting magnitude m(lim), has a minimum shear and redshift calibration accuracy requirements given by epsilon = epsilon(0)10(beta(mlim - 24.5)) (Theta/200)(-1/2). Above that limit, lensing surveys would not reach their full potential. Using the galaxy number counts from the Hubble Ultra-Deep Field, we find (epsilon(0), beta) = (0.015, -0.18) and (epsilon(0), beta) = (0.011, -0.23) for ground and space based surveys respectively. Lensing surveys with no or limited redshift information and/or poor shear calibration accuracy will loose their potential to analyse the cosmic shear signal in the sub-degree angular scales, and therefore complete photometric redshift coverage should be a top priority for future lensing surveys.

TI Biased cosmology: Pivots, parameters, and figures of merit SO ASTROPARTICLE PHYSICS LA English DT Article DE cosmology; dark energy; bias; figure of merit ID DARK ENERGY; PROBE AB In the quest for precision cosmology, one must ensure that the cosmology is accurate as well. We discuss figures of merit for determining from observations whether the dark energy is a cosmological constant or dynamical, with special attention to the best determined equation of state value, at the "pivot" or decorrelation redshift. We show this is not necessarily the best lever on testing consistency with the cosmological constant, and moreover is subject to bias. The standard parametrization of v(a) = w(0) + w(a)(1 - a) by contrast is quite robust, as tested by extensions to higher order parametrizations and modified gravity. Combination of complementary probes gives strong immunization against inaccurate, but precise, cosmology. Published by Elsevier B.V.

The SDSS data thus constrain the redshift of overlap of cosmic H II regions to z(OVL) = 6.1 +/- 0.15. At higher redshifts, the simulations are far from convergence on the mean Gunn-Peterson optical depth but achieve good convergence for the mean neutral hydrogen fraction. The simulations that fit the SDSS data, however, do not have nearly enough resolution to resolve the earliest episodes of star formation and are very far from converging on the precise value of the optical depth to Thomson scattering-any value between 6% and 10% is possible, depending on the convergence rate of the simulations and the fractional contribution of Population III stars. This is generally consistent with the third-year WMAP results, but much higher resolution simulations are required to come up with the sufficiently precise value for the Thomson optical depth that can be statistically compared with the WMAP data.

We compare a set of simulations using a single cosmological realization but with a wide range of WDM particle masses that have not yet been conclusively ruled out by observations. The addition of a WDM component to the initial power spectrum results in a delay in the collapse of high-density gas at the center of the most massive halo in the simulation and, as a result, an increase in the virial mass of this halo at the onset of baryon collapse. Both of these effects become more pronounced as the WDM particle mass becomes smaller. A cosmology using a gravitino WDM power spectrum assuming a particle mass of m(WDM) similar or equal to 40 keV is effectively indistinguishable from the cold dark matter case, whereas the m(WDM) similar or equal to 15 keV case delays star formation in the parent halo by similar or equal to 10(8) yr. There is remarkably little scatter between simulations in the final properties of the protostar that forms at the center of the halo. The detailed evolution of the collapsing halo core in two representative WDM cosmologies is described. At low densities (n(b) less than or similar to 10(5) cm(-3)) the evolution of the two calculations is qualitatively similar, but occurs on significantly different timescales, with the halo in the lower particle mass calculation taking much longer to evolve over the same density range and reach runaway collapse. Once the gas in the center of the halo reaches relatively high densities (n(b) greater than or similar to 10(5) cm(-3)), the overall evolution is essentially identical in the two calculations.

Emission lines are detected in more than half of the red galaxies. We focus on the relationship between two emission lines commonly used as star formation rate indicators: H alpha and [O II] gimel 3727. There is a strong bimodality in [O II]/H alpha ratio in the SDSS sample that closely corresponds to the bimodality in rest-frame color. Nearly all of the line-emitting red galaxies have line ratios typical of various types of AGNs -most commonly LINERs, a small fraction of transition objects, and, more rarely, Seyferts. Only similar to 6% of red galaxies display star-forming line ratios. A straight line in the [O II] -H alpha EW diagram separates LINER-like galaxies from other categories. Quiescent galaxies with no detectable emission lines and LINER-like galaxies combine to form a single, tight red sequence in color-magnitude-concentration space. [O II] EWs in LINER-and AGN-like galaxies can be as large as those in star-forming galaxies. Thus, unless objects with AGN/LINER-like line ratios are excluded, [O II] emission cannot be used directly as a proxy for star formation rate; this is a particular issue for red galaxies. Lack of [O II] emission is generally used to indicate a lack of star formation when poststarburst galaxies are selected at high redshift. Our results imply, however, that these samples have been cut on AGN properties, as well as star formation, and therefore may provide seriously incomplete sets of poststarburst galaxies. Furthermore, poststarburst galaxies identified in SDSS by requiring minimal H alpha EW generally exhibit weak but nonzero line emission with ratios typical of AGNs; few of them show residual star formation. This suggests that most poststarburst galaxies may harbor AGNs/LINERs. C1 Univ Calif Berkeley, Dept Astron, Berkeley, CA 94720 USA. Lawrence Berkeley Natl Lab, Berkeley, CA 94720 USA.

The spectra exhibit prominent absorption bands of H2O at 6.27 mu m, CH4 at 7.65 mu m, and NH3 at 10.5 mu m and are relatively featureless at lambda >= 15 mu m. Three spectral indices that measure the strengths of these bands are presented; H2O absorption features are present throughout the MLT sequence, while the CH4 and NH3 bands first appear at roughly the L/T transition. Although the spectra are, in general, qualitatively well matched by synthetic spectra that include the formation of spatially homogeneous silicate and iron condensate clouds, the spectra of the mid-type L dwarfs show an unexpected flattening from roughly 9 to 11 mu m. We hypothesize that this may be a result of a population of small silicate grains that are not predicted in the cloud models. The spectrum of the peculiar T6 dwarf 2MASS J0937 + 2931 is suppressed from 5.5 to 7.5 mu m relative to typical T6 dwarfs and may be a consequence of its mildly metal-poor/ high surface gravity atmosphere. Finally, we compute bolometric luminosities of a subsample of the M, L, and T dwarfs by combining the IRS spectra with previously published 0.6-4.1 mu m spectra and find good agreement with the values of Golimowski et al., who use L'-and M'-band photometry to account for the flux emitted at lambda > 2.5 mu m.

The primary aim of the project is to probe the material distribution in the extended circumstellar envelopes (CSEs) of evolved stars and recover the fossil record of their mass-loss history. Hence, we must map the whole of the CSEs plus the surrounding sky for background subtraction while avoiding the central star that is brighter than the detector saturation limit. With our unique mapping strategy, we have achieved better than 1 MJy sr(-1) sensitivity in 3 hr of integration and successfully detected a faint (< 5 MJy sr(-1)), extended (similar to 400") far-infrared nebula around the asymptotic giant branch (AGB) star R Hya. Based on the parabolic structure of the nebula, the direction of the space motion of the star with respect to the nebula shape, and the presence of extended Ha emission cospatial to the nebula, we suggest that the detected far-IR nebula is due to a bow shock at the interface of the interstellar medium and the AGB wind of this moving star. This is the first detection of the stellar-wind bow shock interaction for an AGB star and exemplifies the potential of Spitzer as a tool to examine the detailed structure of extended far-IR nebulae around bright central sources.

The conditional sampling or relaxed eddy accumulation (REA), technique represents the first opportunity to directly measure fluxes of reactive gaseous mercury (RGM) to the snow pack in the Arctic. Using a micrometeorological method REA system, with a heated sampling system specifically designed for Arctic use, the dry deposition of RGM is measured after polar sunrise, in Barrow, Alaska. Heated KCl-coated manual RGM annular denuders were used as the accumulators with an inlet allowing only fine particles to pass (Cut off diameter 2.5 mu m). At 3 in above the snow pack significant RGM fluxes were measured each spring in 2001-2004. Both depositions and emissions were observed. The emissions were attributed to chemical formation of RGM at or near the snow surface. The surface resistance, R-c, for RGM was found to be very small and set to zero as a first estimate.

The highly intense X-ray beam caused a significant decrease of the carboxyl peak intensity at 288 eV, to the benefit of a newly arising carbonate peak at 291.2eV. The same phenomenon was found in alginic acid when exposed to the same conditions. With knowledge of the molecular structure of alginic acid, we are able to propose a simple photochemical reaction scenario that describes a decay path for carboxyl in soot: the radiolysis of carboxylate into carbonate in diesel soot during irradiation.

TI Crystallographic studies of the binding of ligands to the dicarboxylate site of Complex II, and the identity of the ligand in the "oxaloacetate-inhibited" state SO BIOCHIMICA ET BIOPHYSICA ACTA-BIOENERGETICS LA English DT Article; Proceedings Paper CT Bari Conference on Mitochondria and Bioenergetics CY DEC, 2005 CL Bari, ITALY DE membrane protein; protein crystallography; X-ray structure; electron transport; redox enzyme; succinate dehydrogenase ID SUCCINATE-DEHYDROGENASE; FUMARATE REDUCTASE; WOLINELLA-SUCCINOGENES; RESPIRATORY COMPLEX; ACTIVATION; FLAVOCYTOCHROME; OXALACETATE; OXIDATION; ANGSTROM; ENZYME AB Mitochondrial Complex II (succinate:ubiquinone oxidoreductase) is purified in a partially inactivated state, which can be activated by removal of tightly bound oxaloacetate (E.B. Kearney, et al., Biochem. Biophys. Res. Commun. 49 1115-1121). We crystallized Complex II in the presence of oxaloacetate or with the endogenous inhibitor bound. The structure showed a ligand essentially identical to the "malate-like intermediate" found in Shewanella Flavocytochrome c crystallized with fumarate (P. Taylor, et al., Nat. Struct. Biol. 6 1108-1112) Crystallization of Complex II in the presence of excess fumarate also gave the malate-like intermediate or a mixture of that and fumarate at the active site. In order to more conveniently monitor the occupation state of the dicarboxylate site, we are developing a library of UV/Vis spectral effects induced by binding different ligands to the site. Treatment with fumarate results in rapid development of the fumarate difference spectrum and then a very slow conversion into a species spectrally similar to the OAA-liganded complex. Complex II is known to be capable of oxidizing malate to the enol form of oxaloacetate (YO. Belikova, et al., Biochim. Biophys. Acta 936 1-9). The observations above suggest it may also be capable of interconverting fumarate and malate. It may be useful for understanding the mechanism and regulation of the enzyme to identify the malate-like intermediate and its pathway of formation from oxaloacetate or fumarate.

TI Microfluidic electroporation of robust 10-mu m vesicles for manipulation of picoliter volumes SO BIOELECTROCHEMISTRY LA English DT Article DE electroporation; electropermeabilization; giant vesicle; giant liposome; sample management ID SINGLE-CELL; CHIP; LIPOSOMES; PERMEABILIZATION; CONTAINERS; FLOW AB We present a new way to transport and handle picoliter volumes of analytes in a microfluidic context through electrically monitored electroporation of 10-25 mu m vesicles. in this method, giant vesicles are used to isolate analytes in a microfluidic environment. Once encapsulated inside a vesicle, contents will not diffuse and become diluted when exposed to pressure-driven flow. Two vesicle compositions have been developed that are robust enough to withstand electrical and mechanical manipulation in a microfluidic context. These vesicles can be guided and trapped, with controllable transfer of material into or out of their confined environment. Through electroporation, vesicles can serve as containers that can be opened when mixing and diffusion are desired, and closed during transport and analysis. Both vesicle compositions contain lecithin, an ethoxylated phospholipid, and a polyelectrolyte. Their performance is compared using a prototype microfluidic device and a simple circuit model. It was observed that the energy density threshold required to induce breakdown was statistically equivalent between compositions, 10.2 +/- 5.0 mJ/m(2) for the first composition and 10.5 +/- 1.8 mJ/m(2) for the second. This work demonstrates the feasibility of using giant, robust vesicles with microfluidic electroporation technology to manipulate picoliter volumes on-chip. (c) 2065 Elsevier B.V.

We examined patterns of soil CO2 efflux using five different methods: auto-chambers, portable gas analyzers, eddy covariance along and two models parameterized with the observed data. The relation between soil temperature and soil moisture with soil CO2 effluxes are also investigated, both inter-annually and seasonally, using these observations/results. Soil respiration rates (R-soil) are greatest during the growing season when soil temperatures are between 15 and 25 degrees C, but some soil CO2 efflux occurs throughout the year. Measured soil respiration was sensitive to soil temperature, particularly during the spring and fall. All measurement methods produced similar annual estimates. Depending on the time of the year, the eddy covariance (flux tower) estimate for ecosystem respiration is similar to or slightly lower than estimates of annual soil CO2 efflux from the other methods. As the eddy covariance estimate includes foliar and stem respiration which the other methods do not; it was expected to be larger (perhaps 15-30%). The auto-chamber system continuously measuring soil CO2 efflux rates provides a level of temporal resolution that permits investigation of short- to longer term influences of factors on these efflux rates. The expense of building and maintaining an auto chamber system may not be necessary for those researchers interested in estimating R-soil annually, but auto-chambers do allow the capture of data from all seasons needed for model parameterization.

Cellulose produced by Gluconacetobacter hansenii was purified and sequentially incubated in solutions of calcium chloride followed by sodium phosphate dibasic. A substantial amount of apatite (50-90% of total dry weight) was homogeneously incorporated throughout the hydrogel after this treatment. X-ray diffractometry (XRD) showed that CdHAP crystallites had formed in the cellulose. XRD further demonstrated that the CdHAP was comprised of 10-50 nm anisotropic crystallites elongated in the c-axis, similar to natural bone apatite. Fourier transform infrared (FTIR) spectroscopy demonstrated that hydroxyl IR bands of the cellulose shifted to lower wave numbers indicating that a coordinate bond had possibly formed between the CdHAP and the cellulose hydroxyl groups. FTIR also suggested that the CdHAP had formed from an octacalcium phosphate precursor similar to physiological bone. Scanning electron microscopy (SEM) images confirmed that uniform similar to 1 mu m spherical CdHAP particles comprised of nanosized crystallites with a lamellar morphology had formed in the cellulose. The synthesis of the composite mimics the natural biomineralization of bone indicating that bacterial cellulose can be used as a template for biomimetic apatite formation. This composite may have potential use as an orthopedic biomaterial. (c) 2006 Elsevier Ltd. All rights reserved. C1 Univ Tennessee, Dept Mat Sci & Engn, Knoxville, TN 37996 USA.

This study suggests a framework to reduce uncertainties in biomechanical systems using limited data sets. The study also shows how sparse data and epistemic input can be exploited using fuzzy logic to represent biomechanical relations. An example application to model collagen fibre recruitment in the medial collateral ligaments during time-dependent deformation under cyclic loading (creep) is presented.

Compounds 6a-c are potent free radical scavengers as demonstrated by the EC50 values in PC12 cell survival assay in term of NO, H2O2, and (OH)-O-. scavenging activity. The Ach-induced vaso-relaxation assay further confirms the potent NO scavenging activity of compounds 6a-c. In addition, 6a-c are efficacious in a rat arterial thrombosis, and are active in ADP- or PAF-induced in vitro platelet aggregation assay, suggesting that compounds 6a-c also possess anti-thrombotic activities. Since both free radical and thrombogenesis are important risk factors in myocardial ischemic/reperfusion injuries, these dual-acting agents having both free radical scavenging and antithrombolic activities may potentially be beneficial toward their treatment.

Two experimental HRPs (surface area 1.54 m(2) and depth 0.3 m). each with a clarifier in series (surface area 0.025 m(2)), were operated in parallel with different hydraulic retention times (3-10 days) but with the same environmental conditions over a period of one year. The operating strategies adopted only yielded a significant overall difference in removal between the two HRPs for nutrients. Effluent total suspended solids and chemical oxygen demand were slightly higher at midday than at dawn, while for total nitrogen and total phosphorous the concentrations were slightly higher at dawn. All these differences were related to the diurnal changes of DO and pH.

A reduction in cellulase production cost, an improvement in cellulase performance, and an increase in sugar yields are all vital to reduce the processing costs of biorefineries. Improvements in specific cellulase activities for non-complexed cellulase mixtures can be implemented through cellulase engineering based on rational design or directed evolution for each cellulase component enzyme, as well as on the reconstitution of cellulase components. Here, we review quantitative cellulase activity assays using soluble and insoluble substrates, and focus on their advantages and limitations. Because there are no clear relationships between cellulase activities on soluble substrates and those on insoluble substrates, soluble substrates should not be used to screen or select improved cellulases for processing relevant solid substrates, such as plant cell walls. Cellulase improvement strategies based on directed evolution using screening on soluble substrates have been only moderately successful, and have primarily targeted improvement in thermal tolerance. Heterogeneity of insoluble cellulose, unclear dynamic interactions between insoluble substrate and cellulase components, and the complex competitive and/or synergic relationship among cellulase components limit rational design and/or strategies, depending on activity screening approaches. Herein, we hypothesize that continuous culture using insoluble cellulosic substrates could be a powerful selection tool for enriching beneficial cellulase mutants from the large library displayed on the cell surface.

In this study, QDs, conjugated with streptavidin, were used to produce fluorescent signals while magnetic beads (MBs) were used to isolate and concentrate the signals. The presence of target DNAs leads to the sandwich hybridization between the functionalized QDs, the target DNAs and the MBs. In fact, the QDs-MBs complex, which is bound using the target DNA, can be isolated and then concentrated. The binding of the QDs to the surface of the MBs was confirmed by confocal microscopy and Cd elemental analysis. It was found that the fluorescent intensity was proportional to concentration of the target DNA, while the presence of non-complementary DNA produced no significant fluorescent signal. in addition, the presence of low copies of target DNAs such as 0.5 pM in large volume samples up to 40 mL was successfully detected by using a magnet-assisted concentration protocol which consequently results in the enhancement of the sensitivity more than 100-fold.

TI Sequential treatment of ovariectomized mice with bFGF and risedronate restored trabecular bone microarchitecture and mineralization SO BONE LA English DT Article DE bFGF; risedronate; mineralization; bone strength; TGF-beta 1 ID FIBROBLAST-GROWTH-FACTOR; PARATHYROID-HORMONE; TGF-BETA; OSTEOPENIC RATS; POSTMENOPAUSAL OSTEOPOROSIS; INTERMITTENT TREATMENT; SYNCHROTRON-RADIATION; OSTEOBLASTIC CELLS; CANCELLOUS BONE; MASS AB Basic fibroblast growth factor (bFGF), a potent mitogen, has been found to restore trabecular bone mass and connectivity in osteopenic rats. The purpose of this study was to determine how sequential treatment of ovariectomized (OVXed) mice with bFGF followed by risedronate would restore trabecular microarchitecture and improve bone strength through alterations in bone mineralization. Six-month old female Swiss-Webster mice were OVXed or sham-operated and left untreated for 4 weeks to develop osteopenia. At week 5, a group of Sham and OVXed mice were treated with vehicle, and 3 other groups of OVXed mice were treated with bFGF (1 mg/kg daily, s.c., 5x/week) for 3 weeks. At week 8, one group of bFGF-treated mice was sacrificed and the other two bFGF-treated groups were treated with vehicle or risedronate (Ris, 5 mu g/kg, s.c., 3x/week) for an additional 6 weeks. Study endpoints included trabecular microarchitecture by microCT, histomorphometry, bone turnover, degree of bone mineralization (DBM), and whole bone strength for the lumbar vertebral body. Compared to sham-operated animals, OVXed mice had significant reductions in trabecular bone volume, connectivity density, DBM, and bone biomechanical properties (P < 0.05). Treatment with bFGF resulted in higher trabecular bone structure and bone strength compared to pre-treatment sham control (P < 0.05). Treatment of OVXed mice with bFGF for 3 weeks followed by 6 weeks Ris maintained the trabecular microarchitecture gained by bFGF treatment, and DBM and bone strength were restored to baseline control levels. Also compared to Sham-operated animals, serum TGF-beta 1 was transiently increased after OVX, increased an additional 100% after bFGF withdrawal, and decreased by 30% with risedronate. In addition, DBM was the strongest predictor for bone biomechanical properties (R-2 > 0.7, P < 0.001). Serum TGF-beta 1 correlated with bone turnover (DPD/Cr, osteocalcin) and was negatively correlated to DBM. Thus, in osteopenic mice, sequential treatment with bFGF followed by risedronate increased trabecular bone microarchitecture, DBM, and bone strength. In addition, suppression of the serum TGF-beta 1 with risedronate was associated with increased DBM. Therefore, sequential treatment with bFGF and Ris restores trabecular architecture and allows mineralization of bone to increase, which appears to be beneficial to bone strength.

Part I: Flow statistics SO BOUNDARY-LAYER METEOROLOGY LA English DT Article DE flow statistics; forest edge; large-eddy simulation; turbulence; wind-tunnel observations ID PLANETARY BOUNDARY-LAYER; REMNANT TREE SWAY; NEUTRALLY STRATIFIED FLOW; SURFACE-ROUGHNESS; AIR-FLOW; STEP CHANGE; DECIDUOUS FOREST; SUDDEN CHANGE; MODEL; WIND AB The statistics of turbulent flow across a forest edge have been examined using large-eddy simulation, and results compared with field and wind-tunnel observations. The moorland-to-forest transition is characterized by flow deceleration in the streamwise direction, upward distortion of the mean flow, formation of a high pressure zone immediately in front of the edge, suppression of the standard deviations and covariance of velocity components, and enhancement of velocity skewnesses. For the selected forest density, it is observed that the maximum distortion angle is about 8 degrees from the horizontal. Instead of approaching a downwind equilibrium state in a monotonic manner, turbulence (standard deviations and covariances of velocity components) and mean streamwise velocity undershoot in the transition zone behind the edge. Evolution of flow statistics clearly reveals the growth of an internal boundary layer, and the establishment of an equilibrium layer downwind of the edge. It is evident that lower-order moments generally adjust more quickly over the new rough surface than do higher-order moments. We also show that the streamwise velocity standard deviation at canopy height starts its recovery over the rough surface sooner than does the vertical velocity standard deviation, but completes full adjustment later than the latter. Despite the limited domain size upstream of the edge, large-eddy simulation has successfully reproduced turbulent statistics in good agreement with field and wind-tunnel measurements.

J. Craig et al., Science 304, 565 (2004)). In particular, the splitting of the zero-bias-peak discovered experimentally is clearly observed in our studies. To understand these results, a simple "circuit model" is introduced and shown to provide a good qualitative description of the experiments. The main idea is that the splitting originates in a Fano anti-resonance, which is caused by having one quantum dot side-connected in relation to the current's path. This scenario provides an explanation of Craig et al.'s results that is alternative to the RKKY proposal, which is here also addressed. C1 Oakland Univ, Dept Phys, Rochester, MI 48309 USA.

The specificities of luteinizing hormone releasing hormone (LHRH) and luteinizing hormone/chorionic gonadotropin (LH/CG)- bound SPIONs were tested in human breast cancer cells in vitro and were found to be dependent on the receptor expression of the target cells, the time of incubation and showed saturation kinetics. In incubations with MDA-MB-435S.luc cells, the highest iron accumulation was 452.6 pg Fe/cell with LHRH-SPIONs, 203.6 pg Fe/cell with beta-CG-SPIONs and 51.3 pg Fe/cell with SPIONs. Incubations at 4 degrees C resulted in 1.1 pg Fe/cell. Co-incubation with the same ligands (beta CG or LHRH) decreased the iron accumulation in each case. LHRH-SPIONs were poorly incorporated by macrophages. Tumors and metastatic cells from breast cancer xenografts were targeted in vivo in a nude mouse model. LHRH-SPION specifically accumulated in cells of human breast cancer xenografts. The amount of LHRH-SPION in the lungs was directly dependent on the number of metastatic cells and amounted to 77.8 pg Fe/metastastic cell. In contrast, unconjugated SPIONs accumulated in the liver, showed poor affinity to the tumor, and were not detectable in metastatic lesions in the lungs. LHRH-SPION accumulated in the cytosolic compartment of the target cells and formed clusters. LHRH-SPIONs did not accumulate in livers of normal mice. In conclusion, LHRH conjugated SPIONs may serve as a contrast agent for MR imaging in vivo and increase the sensitivity for the detection of metastases and disseminated cells in lymph nodes, bones and peripheral organs.

Soil C and N were measured at nine sites along an altitudinal gradient in the southern Appalachian Mountains (Tennessee and North Carolina, USA). Measurements indicated greater labile and total soil C stocks with increasing altitude. Laboratory incubations (3 days) of rewetted, air-dry soils indicated potential soil C mineralization (mu g CO2 produced center dot g(-1) soil C) declined with elevation. A principal component analysis indicated N availability increased with altitude. At each site, there was a significant relationship between C-13 and log-transformed C concentrations in the soil profile (30 cm deep). Enrichment factors (epsilon) from the Rayleigh equation were also equally useful for describing soil C-13 profiles at each site. Soil C partitioning and turnover times along the gradient were correlated with C-13-enrichment factors. Greater rates of change in C-13 through the soil profile were correlated with faster soil C turnover. Environmental factors, soil C partitioning, and the rate of vertical change in soil C-13 abundance are interrelated such that C-13 measurements are a potential indicator of C dynamics in undisturbed forest soils.

The Arnold tongues are wedge-like domains in the parameter space spanned by the forcing amplitude and frequency, within which the oscillator's frequency is locked to a fraction of the forcing frequency. Spatial patterning can modify these domains. We describe here two pattern formation mechanisms affecting frequency locking at half the forcing frequency. The mechanisms are associated with phase-front instabilities and a Turing-like instability of the rest state. Our studies combine experiments on the ruthenium catalyzed light-sensitive Belousov-Zhabotinsky reaction forced by periodic illumination, and numerical and analytical studies of two model systems, the FitzHugh-Nagumo model and the complex Ginzburg-Landau equation, with additional terms describing periodic forcing.

The equilibrium isotherm was accurately approximated by a multilayer model assuming lateral interactions between adsorbed molecules. The parameters of the kinetics of the phenol mass transfer in this column were measured by the method of moments. These data were analyzed using the available models and correlations. It was proven that the parameters of the mass transfer kinetics measured under linear conditions could be successfully used for the prediction of the concentration profiles obtained under overloaded conditions.

For instance, 1a, [Fe-3(III)(mu(3)-O)(CH2=CHCOO)(6)(H2O)(3)](+), crystallizes in the chiral space group P3(1) as a chloride salt. Crystallization of 1b, [Fe-3(mu(3)-O)-(C2H3CO2)(6)(H2O)(3)]NO3 center dot 4.5H(2)O, from aqueous solution followed by recrystallization from acetonitrile also gives rise to spontaneous resolution to yield the homochiral salt [Fe-3(mu(3)-O)(C2H3CO2)(6)(H2O)(3)]NO3 center dot CH3CN of 1c (space group P2(1)2(1)2(1)). Furthermore, the reaction of 1a with hexamolybdate in acetonitrile gives the helical coordination polymer {[(Fe-3(mu(3)-O)L-6(H2O))(MoO4)(Fe-3(mu(3)-O)L-6(H2O)(2))]center dot 2CH(3)CN center dot H2O}(infinity). 2 (L: H2C=CHCOO), which crystallizes in the space group P2(1). The nature of the ligand geometry allows the formation of atropisomers in both the discrete (1a-c) and linked {Fe-3} clusters (2), which is described along with a magnetic analysis of 1a and 2.

The structures of several species present in both Mycobacteria (TUBags1-4) and in Escherichia coli have been reported to contain a formyl-alkyl diphosphate core. Here we report the synthesis of the lead member of the series, 3-formyl-1-butyl diphosphate. This compound has low activity for gamma delta T cell stimulation, unlike its highly active isomer (E)-4-hydroxy-3-methyl-but-2-enyl diphosphate, necessitating a revision of the structure of TUBag1. Likewise, the structure of the species identified as the pentyl analog (TUBag2) is revised to 6-phosphogluconate. These results indicate that neither TUBag1 nor the m/e 275 species proposed for TUBag2 are 3-formyl-1-alkyl diphosphates, leading to the conclusion that none of the natural phosphoantigens (TUBags1-4) possess the structures reported previously.

Substrate inhibition is commonly avoided by diluting the waste before treatment, however, dilution of a waste before treatment is not always feasible. In the case of radioactive mixed wastes and chemical warfare materiel (CWM), dilution presents regulatory and safety concerns. In this study, we investigated a "drip-feed" reactor configuration as an alternative approach for the biological treatment of concentrated waste streams with minimal dilution and complete containment. In the drip-feed reactor undiluted waste is slowly fed to biomass in a reactor at a rate sufficient to maintain activity, but at a low enough rate so that bacterial degradation maintains the reactor concentration below the toxic threshold. The reactor has no effluent, but rather fills as the undiluted waste is fed to the reactor, which has the advantage of preventing the release of hazardous material into the environment during treatment. Volatile releases are prevented with the use of condensers. The drip-feed bioreactor configuration was tested under aerobic conditions, at 25 degrees C, using a 10% acetonitrile feed solution. The treatment of acetonitrile to less than 0.1 mg l(-1) was achieved with a dilution factor of only 3.4. The acetonitrile degradation reaction was pH sensitive, where the optimal pH range for the biodegradation process was approximately between 6.5 and 7.1 and the biodegradation rate declined precipitously above pH 7.2. The applicability of the drip-feed reactor configuration to the treatment of mixed wastes and CWM is discussed. (c) 2006 Elsevier Ltd. All rights reserved.

A consequence of this suppression of precipitation is increased liquid water available for large-scale stratiform clouds, through detrainment, that in turn affect their precipitation efficiency. The nature of this influence on radiation, however, is dependent on both the treatment of convective condensate and the aerosol distribution. Here, we examine these issues with two climate models-CSIRO and GISS, which treat detrained condensate differently. Aerosol-cloud interactions in warm stratiform and cumulus clouds (via cloud droplet formation and autoconversion) are treated similarly in both models. The influence of aerosol-cumulus cloud interactions on precipitation and radiation are examined via simulations with present-day and pre-industrial aerosol emissions. Sensitivity tests are also conducted to examine changes to climate due to changes in cumulus cloud droplet number (N-c); the main connection between aerosols and cumulus cloud microphysics. Results indicate that the CSIRO GCM is quite sensitive to changes in aerosol concentrations such that an increase in aerosols increases N-c, cloud cover, total liquid water path (LWP) and reduces total precipitation and net cloud radiative forcings. On the other hand, the radiative fluxes in the GISS GCM appear to have minimal changes despite an increase in aerosols and N-c. These differences between the two models-reduced total LWP in the GISS GCM for increased aerosols, opposite to that seen in CSIRO-appear to be more sensitive to the detrainment of convective condensate, rather than to changes in N (c). If aerosols suppress convective precipitation as noted in some observationally based studies (but not currently treated in most climate models), the consequence of this change in LWP suggests that: (1) the aerosol indirect effect (calculated as changes to net cloud radiative forcing from anthropogenic aerosols) may be higher than previously calculated or (2) lower than previously calculated. Observational constrains on these results are difficult to obtain and hence, until realistic cumulus-scale updrafts are implemented in models, the logic of detraining non-precipitating condensate at appropriate levels based on updrafts and its effects on radiation, will remain an uncertainty.

The paper puts particular emphasis on understanding how optimal near-term R&D expenditures might vary based on the technologies pursued in the R&D program. The exploration is conducted in the context of varying impacts from R&D on the global abatement cost function. The R&D planning problem is considered first within a theoretical framework and is then pursued in a stylized application using the DICE model. The paper provides intuition into the circumstances under which near-term technology R&D might increase or decrease under uncertainty, thereby serving as a hedge against climate uncertainty.

As a result, there appears to be a relatively rapid change in the burning-rate response over a certain range of overpressures in which the sensitivity, or slope, of the propagation speed as a function of overpressure transitions from relatively small to large values. This is often referred to as a transition from "conductive to "convective burning, corresponding to the increased role played by convective gas transport relative to thermal diffusion in determining the propagation speed of the deflagration. In the present work, we consider the analysis of a two-temperature model in which finite-rate interphase heat-transfer effects also play an important role in determining the burning-rate eigenvalue. In particular, we revisit a physically relevant scenario in which the first effects of temperature nonequilibrium are felt in the thin multiphase reaction region, with the preheat zone remaining in thermal equilibrium to a first approximation. Expanding on previous asymptotic results that are further specialized to certain limiting parameter regimes, we consider a combination of analytical and numerical approaches to obtain solutions in the chemical boundary layer, and hence the burning-rate eigenvalue, for a significantly wider range of parameters. In particular, we are able to address a greater range of resistance to interphase heat transfer and thus determine an upper limit beyond which interphase temperature differences are no longer negligible in the preheat region. The main result is that, relative to earlier single-temperature models in which temperature-nonequilibrium effects are completely neglected, the burning-rate response exhibits a much sharper transition from the conduction- to the convection-dominated regime. This results from the ability of the reactive phase to retain a greater amount of the heat of reaction, causing a rapid increase in the reaction rate as the local temperature in that phase exceeds both the corresponding single-temperature value and even the final burned temperature.

The stress distributions around the interacting inclusions are computed by using Eshelby's equivalent inclusion method (EIM) with constant, linear, or quadratic eigenstrains. A Taylor series expansion is employed to find the approximate solution of the EIM consistency equations. The effect of the location of a point around which a Taylor expansion is carried out on the accuracy of the EIM solution is also investigated. In addition to the EIM, finite element computations are performed to establish the robustness and accuracy of the analytical method. After validating the EIM approach, the effect of the distribution pattern of the inclusions on the radial interface stresses around several interacting inclusions is examined. (c) 2005 Elsevier B.V.

Such spaces remain a popular choice in the engineering practice because they offer the convenience of simple and uniform data structures and reasonable accuracy. A consistently stabilized method [20] and a least-squares formulation [18] are compared with two new stabilized methods. The first one is an extension of a recently proposed polynomial pressure projection stabilization of the Stokes equations [5,13]. The second one is a weighted average of a mixed and a Galerkin principles for the Darcy problem, and can be viewed as a consistent version of the classical penalty stabilization for the Stokes equations [8]. Our main conclusion is that polynomial pressure projection stabilization is a viable stabilization choice for low order C-0 approximations of the Darcy problem.

The time evolution is carried out by evolving the Euler equations explicitly and the neutrino transport equations implicitly. Neutrino transport is modeled by the multi-group Boltzmann transport (MGBT) and the multi-group flux limited diffusion (MGFLD) equations. An implicit time stepping scheme for the MGBT and MGFLD equations yields Jacobian systems that necessitate scaling and preconditioning. Two types of preconditioners, namely, a sparse approximate inverse (SPAI) preconditioner and a preconditioner based on the alternating direction implicit iteration (ADI-like) have been found to be effective for the MGFLD and MGBT formulations. This paper compares these two preconditioners. The ADI-like preconditioner performs well with both MGBT and MGFLD systems. For the MGBT system tested, the SPAI preconditioner did not give competitive results. However, since the MGBT system in our experiments had a high condition number before scaling and since we used a sequential platform, care must be taken in evaluating these results.

Yet, despite these successes, remarkably little research has been devoted to developing an understanding of why tabu search is so effective on this problem class. In this paper, we report results that provide significant progress in this direction. We consider Nowicki and Smutnicki's i-TSAB tabu search algorithm, which represents the current state-of-the-art for the makespan-minimization form of the classical job-shop scheduling problem. Via a series of controlled experiments, we identify those components of i-TSAB that enable it to achieve state-of-the-art performance levels. In doing so, we expose a number of misconceptions regarding the behavior and/or benefits of tabu search and other local search metaheuristics for the job-shop problem. Our results also serve to focus future research, by identifying those specific directions that are most likely to yield further improvements in performance. (c) 2005 Elsevier Ltd.

TI Methods for accessing pitting damage in carbon steel exposed to alkaline chloride waste environments SO CORROSION LA English DT Article DE carbon steel; electrochemical noise; generalized extreme value statistics; potentiodynamic polarization; potentiostatic metastable pitting; radioactive waste ID ELECTROCHEMICAL NOISE; CORROSION AB Several laboratory methods for accelerated testing have been evaluated and their abilities to access pitting damage during immersion in environments that simulate high-level radioactive waste have been compared. Specifically, we examine and compare corrosion current density, open-circuit potential (OCP), metastable pitting data, and electrochemical noise (EN) data. In our work, a novel method for evaluating EN data has been analyzed. In this method, generalized extreme value (GEV) statistics is used to evaluate the distribution of current transient events greater than 10 mu C. We show how the GEV cumulative distribution function from these EN events can be used to access relative pitting damage. Specifically, we demonstrate that the GEV distribution of EN events that exceed a 10-mu C threshold correlates well with actual surface damage. However, EN experiments do not appear to predict future damage when compared to 3-month immersion testing. Therefore, while short-term changes in EN data may be good indicators of real-time material behavior, limited EN sample time (weeks) should not be used as an indicator of long-term performance.

TI Potential soil carbon sequestration and CO2 offset by dedicated energy crops in the USA SO CRITICAL REVIEWS IN PLANT SCIENCES LA English DT Review DE bioenergy plantations; global warming; land use conversion; soil organic carbon; terrestrial C sequestration ID CONSERVATION RESERVE PROGRAM; LOCUST ROBINIA-PSEUDOACACIA; FRACTION ORGANIC-MATTER; GLOBAL CLIMATE-CHANGE; CENTRAL UNITED-STATES; WILLOW BIOMASS CROPS; LOBLOLLY-PINE; LIGHT-FRACTION; BIOENERGY CROP; LAND-USE AB Energy crops are fast-growing species whose biomass yields are dedicated to the production of more immediately usable energy forms, such as liquid fuels or electricity. Biomass-based energy sources can offset, or displace, some amount of fossil-fuel use. Energy derived from biomass provides 2 to 3% of the energy used in the U.S.A.; but, with the exception of corn-(Zea mays L.)-to-ethanol, very little energy is currently derived from dedicated energy crops. In addition to the fossil-fuel offset, energy cropping might also mitigate an accentuated greenhouse gas effect by causing a net sequestration of atmospheric C into soil organic C (SOC). Energy plantations of short-rotation woody crops (SRWC) or herbaceous crops (HC) can potentially be managed to favor SOC sequestration. This review is focused primarily on the potential to mitigate atmospheric CO2 emissions by fostering SOC sequestration in energy cropping systems deployed across the landscape in the United States. We know that land use affects the dynamics of the SOC pool, but data about spatial and temporal variability in the SOC pool under SRWC and HC are scanty due to lack of well-designed, long-term studies. The conventional methods of studying SOC fluxes involve paired-plot designs and chronosequences, but isotopic techniques may also be feasible in understanding temporal changes in SOC. The rate of accumulation of SOC depends on land-use history, soil type, vegetation type, harvesting cycle, and other management practices. The SOC pool tends to be enhanced more under deep-rooted grasses, N-fixers, and deciduous species. Carbon sequestration into recalcitrant forms in the SOC pool can be enhanced with some management practices (e.g., conservation tillage, fertilization, irrigation); but those practices can carry a fossil-C cost. Reported rates of SOC sequestration range from 0 to 1.6 Mg C ha(-1) yr(-1) under SRWC and 0 to 3 Mg C ha(-1) yr(-1) under HC. Production of 5 EJ of electricity from energy crops-a perhaps reasonable scenario for the U.S.A.-would require about 60 Mha. That amount of land is potentially available for conversion to energy plantations in the U.S.A. The land so managed could mitigate C emissions (through fossil C not emitted and SOC sequestered) by about 5.4 Mg C ha(-1) yr(-1). On 60 Mha, that would represent 324 Tg C yr(-1)-a 20% reduction from current fossil-fuel CO2 emissions. Advances in productivity of fast-growing SRWC and HC species suggest that deployment of energy cropping systems could be an effective strategy to reduce climate-altering effects of anthropogenic CO2 emissions and to meet global policy commitments.

An accelerometer array that had been upgraded after the Northridge earthquake recorded the motion with 17 channels on the dam and the dam-foundation interface. Using this data, properties of the first two modes are found from a system identification study. Modal properties are also determined from a forced vibration experiment performed in 2002 and indicate a significantly stiffer system than is estimated from the 2001 earthquake records. The 2001 earthquake, although small, must have induced temporary nonlinearity. This has implications for structural health monitoring. The source of the nonlinear behaviour is believed to be loss of stiffness in the foundation rock. A finite element model of Pacoima Dam is constructed and calibrated to match modal properties determined from the system identification study. A dynamic simulation of the 2001 earthquake response produces computed motions that agree fairly well with the recorded ones. Copyright (C) 2006 John Wiley & Sons, Ltd.

TI Generation of spatially nonuniform ground motion for nonlinear analysis of a concrete arch dam SO EARTHQUAKE ENGINEERING & STRUCTURAL DYNAMICS LA English DT Article DE Pacoima Dam; spatially nonuniform ground motion; pseudostatic response; generated abutment motion; Northridge earthquake; finite element analysis AB An accelerometer array at Pacoima Dam with three locations along the base and abutments recorded ground motion from a magnitude 4.3 earthquake on 13 January 2001. These records present an opportunity to study spatial nonuniformity for the motion in a canyon. Topographic amplification is characterized by ratios of response spectral displacement between locations, and seismic wave travel times are studied using cross-correlation functions to obtain delays. Results of the analysis of the 2001 earthquake records are used to generate ground motion for the 1994 Northridge earthquake to replace records that were not able to be fully digitized. The ground motion generated for the Northridge earthquake is used as input to a finite element model of Pacoima Dam. The response of the model is consistent with observations of Pacoima Dam after the Northridge earthquake. Comparison of the response due to nonuniform input with the response due to uniform input demonstrates the importance of accounting for spatial nonuniformity because of the significance that the pseudostatic component has for the response to nonuniform input.

The results are discussed broadly in terms of the complexity of intergrown and disordered xLi(2)MnO(3) center dot (1 - x)LiMO2 systems, particularly when cobalt is combined with manganese and nickel in the transition metal layers of the LiMO2 component. It is proposed that the addition of trivalent cobalt to the transition metal layers in the Li1+x[Mn0.333Ni0.333Co0.333](1-x)O-2 compounds at the expense of tetravalent manganese and divalent nickel reduces the amount and size of the Li2MnO3-like regions, rendering them essentially amorphous to X-ray diffraction.

Ultrasensitive native fluorescence detection of proteins with miniaturized 1-D and 2-D PAGE was achieved with laser side-entry excitation. The detection limit for R-phycoerythrin protein spots in 1-D SDS-PAGE with 532 nm excitation was as low as 15 fg, which corresponds to only 40 000 molecules. The average detection limit of six standard native proteins was 5 pg per band with 275 nm excitation. The dynamic range spanned more than three orders of magnitude. By using the same detection setup, approximately 150 protein spots from 30 ng of total Escherichia coli extraction were detected on a 0.8 cm x 1 cm gel in 2-D separation. The significant improvement in sensitivity for laser side-entry excitation comes from higher excitation power and lower background level compared with other excitation modes.

Thermodynamic analyses were done for energy utilization according to energy balance and compared with the measured data. Our experimental results indicate that the effective energy efficiency in most melting furnaces measured is around 26-29%, and the major heat loss through flue gas is between 35% and 50%. The energy availability concept is introduced to predict the maximum energy potential and minimum flue gas heat loss in this type of aluminum furnace. Pollutant formation and control of nitrogen oxides and greenhouse gas are discussed. Methods that may improve energy efficiency and reduce pollutant emissions from melting operations are also addressed. (c) 2005 Elsevier Ltd. All rights reserved.

TI Cost of power interruptions to electricity consumers in the United States (US) SO ENERGY LA English DT Article DE power interruption; power outage; bottom-up approach; power quality; electric power reliability ID END-USE; RELIABILITY AB The massive electric power blackout in the northeastern US and Canada on August 14-15, 2003 catalyzed discussions about modernizing the US electricity grid. Industry sources suggested that investments of $50-100 billion would be needed. This work seeks to better understand an important piece of information that has been missing from these discussions: what do power interruptions and fluctuations in power quality (power-quality events) cost electricity consumers? We developed a bottom-up approach for assessing the cost to US electricity consumers of power interruptions and power-quality events (referred to collectively as "reliability events"). The approach can be used to help assess the potential benefits of investments in improving the reliability of the grid. We developed a new estimate based on publicly available information, and assessed how uncertainties in these data affect this estimate using sensitivity analysis. (c) 2006 Elsevier Ltd.

This decline was based on the assumption that costs of reducing carbon emissions are lower in developing Countries than elsewhere. In this paper, we test this hypothesis by estimating the cost of reducing emissions through the use of combined cycle units in place of coal power plants in India. Using data from power plants proposed by independent power producers, we estimate the cost of carbon reduction to be $144/t C. Capital, fuel and other costs are all higher for combined cycles units in India than in the US, while they are comparable for the technologically mature coal plants in the two countries. As the combined cycle technology matures, the cost differential may narrow in the future to as low as $6/t C. A key conclusion of this study is that to the extent project-based activities, e.g., under CDM, rely on new technologies to reduce carbon emissions from similar sources, the cost of carbon reduction may be higher in developing countries, since new technology costs in a nascent market are often higher in these countries.

Combining the theoretical framework of 'learning by doing' and developments in 'learning by searching' with the fields of organizational learning and institutional economics offers a complete methodological framework to examine the underlying capital cost trajectory when developing electricity cost estimates used in energy policy planning models. Sensitivities of the learning rates for global wind and solar photovoltaic technologies to changes in the model parameters are tested. The implications of the results indicate that institutional policy instruments play an important role for these technologies to achieve cost reductions and further market adoption.

EE/RE are potentially important contributors to national productive capital accumulation, enhancement of the environment, expansion of energy services, increases in household standard of living, and improvements in health. In this study, we develop a spreadsheet model for calculating some of the national benefits and costs of different levels of investment in EE/RE. We then present the results of the model in terms of investment demand and investment scenario curves. These curves express the contribution that efficiency and renewable energy projects can make in terms of reduced energy sector operating expenses, and reduced carbon emissions. We provide demand and supply curves that show the rate of return, the cost of carbon emissions reductions vs. supply, and the evolution of the marginal carbon emissions per dollar of GDP for different investment levels and different fuel-type subsectors.

In some countries a large number of ESCOs have been successfully operating for a number of years, while in other countries only a few ESCOs have recently started to operate. This difference could be explained by several factors, such as different levels of support offered to ESCOs by national and regional energy authorities, local market structures and rules, and variation in the definitions, roles and activities of ESCOs. This paper reviews and analyses the development and the current status of ESCO industries in the EU and the New Accession Countries. Based on the review and the analysis, a long-term strategy to foster the development of ESCOs in Europe is formulated. The strategic actions recommended build on successful experience in Europe and are proposed with an eye to existing and planned legislative measures, such as the proposed Energy Service Directive and the deployment of the Kyoto flexible mechanisms.

Implementations of the scheme must deal with all possible geometric configurations, which results in a large number of cases that in turn result in practical programming issues. In this article, we address this issue with a Python script that generates C++ code using the symmetric group G(4) acting over canonical topological and geometric configurations. We then analyze the performance of the technique by characterizing (a) mesh quality, (b) execution time and parallel speedup, and (c) traits of the algorithm that could affect quality or execution time differently for different meshes and different mesh refinement strategies. This article also details the method used to debug the many subdivision templates that the algorithm relies upon. Mesh quality is on par with other similar refinement schemes, and we suggest a more elaborate technique that may substantially improve mesh quality. We show that throughput on modern hardware can exceed 600,000 output tetrahedra per second per processor, and that the method is embarrassingly parallel-assuming the application has partitioned the input properly.

TI Measures of preferred direction for environmental and ecological circular data SO ENVIRONMENTAL AND ECOLOGICAL STATISTICS LA English DT Article DE circular Hodges-Lehmann estimate; circular mean; circular median; directional data; nonparametric estimation; robustness; outliers ID ESTIMATORS AB Circular or angular variables indicating direction or cyclical time can be of great interest to scientists studying ecology, biology or environmental issues. A common problem of interest in circular data is estimating a preferred direction and its corresponding distribution. This problem is complicated by the so-called "wrap-around effect" on the circle, which exists because there is no natural minimum or maximum. The usual statistics employed for linear data are inappropriate for directional data, as they do not account for its circular nature. Three choices for summarizing the preferred direction (the sample circular mean, sample circular median and a circular analog of the Hodges-Lehmann estimator) are discussed, with examples from environmental and ecological applications. Similar to the linear data case, the relative emphases of different methods sometimes yield different measures of preferred direction in the presence of outliers or lack of symmetry in the original data.

The reactor was initially inoculated with anoxic denitrifying and strictly anaerobic biomass from two municipal wastewater treatment plants. After successful development of biomass using nitrate and ferric EDTA as the primary electron acceptors and ethanol as the primary electron donor, the system was modified to continuously load nitric oxide in the form of the nitrosyl adduct of ferrous EDTA. The process was operated in this manner for 107 days, including a steady-state period that was maintained for more than 70 days. During the period of steady-state operation, 0.194 mol of NO and 0.166 mol of ethanol were loaded per day. This corresponded with biogas formation at a consistent rate (0.669 liters per day) and composition (0.91 atm of N-2) high NO scrubbing efficiency (97.9% removal), and consistent consumption of neutralizing acid (0.330 acid equivalents per day). Results of process operation and discussion of implications for future process development are presented. C1 Univ Pittsburgh, Dept Civil & Environm Engn, Pittsburgh, PA 15260 USA.

TI Coselection for microbial resistance to metals and antibiotics in freshwater microcosms SO ENVIRONMENTAL MICROBIOLOGY LA English DT Article ID POLLUTION; BACTERIA; MERCURY; COPPER AB Bacterial resistances to diverse metals and antibiotics are often genetically linked, suggesting that exposure to toxic metals may select for strains resistant to antibiotics and vice versa. To test the hypothesis that resistances to metals and antibiotics are coselected for in environmental microbial assemblages, we investigated the frequency of diverse resistances in freshwater microcosms amended with Cd, Ni, ampicillin or tetracycline. We found that all four toxicants significantly increased the frequency of bacterioplankton resistance to multiple, chemically unrelated metals and antibiotics. An ampicillin-resistant strain of the opportunistic human pathogen Ralstonia mannitolilytica was enriched in microcosms amended with Cd. Frequencies of antibiotic resistance were elevated in microcosms with metal concentrations representative of industry and mining-impacted environments (0.01-1 mM). Metal but not antibiotic amendments decreased microbial diversity, and a weeklong exposure to high concentrations of ampicillin (0.01-10 mg l(-1)) and tetracycline (0.03-30 mg l(-1)) decreased microbial abundance only slightly, implying a large reservoir of antibiotic resistance in the studied environment. Our results provide first experimental evidence that the exposure of freshwater environments to individual metals and antibiotics selects for multiresistant microorganisms, including opportunistic human pathogens.

In addition, relative humidity, temperature, and air change rates were measured in homes, and housing characteristics were documented through a questionnaire to occupants. Half of the homes had ventilation rates below 7.5 L/s person. Nitrogen dioxide (NO2) and formaldehyde concentrations ranged from 3.3 to 29.1 mu g/m(3) (geometric mean 8.3 mu g/m(3)) and from 9.6 to 90.0 mu g/m(3) (geometric mean of 29.5 mu g/m(3)), respectively. The housing characteristics documented in the study explained approximately half of the variance of NO2 and formaldehyde. NO2 concentrations in homes were positively correlated with air change rates (indicating a significant contribution of outdoor sources to indoor levels) and were significantly elevated in homes equipped with gas stoves and, to a lesser extent, in homes with gas heating systems. Formaldehyde concentrations were negatively correlated with air change rates and were significantly elevated in homes heated by electrical systems, in those with new wooden or melamine furniture purchased in the previous 12 months, and in those where painting or varnishing had been done in the sampled room in the previous 12 months. Results did not indicate any significant contribution of indoor combustion sources, including wood-burning appliances, to indoor levels of formaldehyde. These results suggest that formaldehyde concentrations in Quebec City homes are caused primarily by off-gassing, and that increasing air change rates in homes could reduce exposure to this compound. More generally, our findings confirm the influence of housing characteristics on indoor concentrations of NO2 and formaldehyde. Crown Copyright (c) 2006 Published by Elsevier Inc.

We estimate that total Hg emissions from all anthropogenic sources increased at an average annual rate of 2.9% during the period 1995-2003, reaching 696 (+/- 307) t in 2003, with a speciation split of 395 t of Hg-0, 230 t of Hg2+, and 70 t of Hg-p. Nonferrous metals smelting and coal combustion continue to be the two leading mercury sources in China, as nonferrous metals production and coal consumption keep increasing. Nonferrous metals smelting and coal combustion together contributed similar to 80% of total Hg emissions during the past decade. Hg emissions from coal combustion increased from 202 t in 1995 to 257 t in 2003 at an average annual rate of 3.0%. Among all of the coal consumption sectors, the power sector is the leading one in Hg emissions growth, up by 5.9% annually. Hg emissions from nonferrous metals smelting increased from 230 t in 1995 to 321 t in 2003 at an average annual rate of 4.2%. Although Hg emissions related to gold smelting decreased since 1996, other nonferrous metals such as zinc, lead, and copper contributed significant Hg growth at annual rates of 8.5%, 13.0%, and 6.9%, respectively. At provincial level, the trends of Hg emissions show significant variation. The uncertainty level decreased from +/- 78% (95% confidence interval) in the estimate of total emissions in 1995, to +/- 44% in 2003. This is primarily attributed to the decreased emissions from those Hg sources with the largest uncertainty in both activity levels and emission factors, such as artisanal gold smelting, mercury mining, and battery/fluorescent lamp production.

Remediation efforts removed most of the sludge from the floodplain, but contamination persists. Clean-up activities also produced clouds of aerosolized materials that further contaminated the surrounding landscape. Whole-body concentrations of 21 elements in the Moorish wall gecko, Tarentola mauritanica, a common inhabitant of both rural and urban areas, were compared among seven locations. Locations spanned an expected contamination gradient and included a rural and an urban non-mine-affected location, two mine-affected towns, and three locations on the contaminated floodplain. Multivariate analyses of whole-body concentrations identified pollutants that increased across the expected contamination gradient, a trend particularly evident for As, Pb, and Cd. Additionally, higher contaminant concentrations occurred in prey items eaten by geckos from mine-affected areas. Comparison of element concentrations in tails and whole bodies suggests that tail clips are a viable nondestructive index of contaminant accumulation. Our results indicate that areas polluted by the mine continue to experience contamination of the terrestrial food chain. Where abundant, geckos represent useful taxa to study the bioavailability of some hazardous pollutants. C1 Univ Georgia, Savannah River Ecol Lab, Aiken, SC 29803 USA.

Until recent years, the positions of protons on the catalytic aspartates and the ligand in these complexes had not been determined with certainty due to the inadequate resolution of these analyses. There has been much interest in locating the catalytic protons at the active site of aspartic proteinases since this has major implications for detailed understanding of the mechanism of action and the design of improved transition state mimics for therapeutic applications. In this review we discuss the results of studies which have shed light on the locations of protons at the catalytic centre. The first direct determination of the proton positions stemmed from neutron diffraction data collected from crystals of the fungal aspartic proteinase endothiapepsin bound to a transition state analogue (H261). The neutron structure of the complex at a resolution of 2.1 angstrom provided evidence that Asp 215 is protonated and that Asp 32 is the negatively charged residue in the transition state complex. Atomic resolution X-ray studies of inhibitor complexes have corroborated this finding. A similar study of the native enzyme established that it, unexpectedly, has a dipeptide bound at the catalytic site which is consistent with classical reports of inhibition by short peptides and the ability of pepsins to catalyse transpeptidation reactions. Studies by NMR have confirmed the findings of low-barrier and single-well hydrogen bonds in the complexes with transition state analogues.

The neutron resolution could be achieved only with the ab initio fully deuterated protein and the subsequent crystallization in D(2)O of the complex. We used the largest good-quality crystal (1.00 x 0.67 x 0.23 mm, i.e. volume of 0.15 mm(3)) that we were able to grow so far. Both studies enable the determination of protonation states, with a clear advantage for neutrons in the case of less-ordered atoms (B > 5 angstrom(2)). Hydrogen atoms are best determined by a complementary analysis of the Fourier maps obtained from both methods. C1 ULP, INSERM, CNRS, IGBMC, F-67404 Strasbourg, France.

However, whilst it is often difficult to determine the position of hydrogen atoms using X-ray crystallography even with subatomic (< 1.0 angstrom) resolution data available, neutron crystallography provides an experimental tool to directly localize hydrogen/deuterium atoms in biological macromolecules at resolution of 1.5-2.0 angstrom. D-Xylose isomerase (D-xylose ketol-isomerase, EC 5.3.1.5) is a 43 kDa enzyme that catalyses the first reaction in the catabolism of D-xylose. Linearization and isomerization of D-xylose at the active site of D-xylose isomerase rely upon a complex hydrogen transfer. Neutron quasi-Laue data at 2.2 angstrom resolution were collected at room temperature on a partially deuterated Streptomyces rubiginosus D-xylose isomerase crystal using the LADI instrument at ILL with the objective to provide insight into the enzymatic mechanism. The neutron structure shows unambiguously that residue His 53 is doubly protonated at the active site of the enzyme. This suggests that the reaction proceeds through an acid catalyzed opening of the sugar ring, which is in accord with the mechanism suggested by Fenn et al. (Biochemistry 43(21): 6464-6474, 2004). This is the first report of direct observation of double protonation of His 53 and the first validation of the ring opening mechanism at the active site of D-xylose isomerase.

These studies are providing unique and complementary insights on hydrogen and hydration in protein crystal structures that are not available from X-ray structures alone. Parallel improvements in modern molecular biology now allow fully (per)deuterated protein samples to be produced for neutron scattering that essentially eradicate the large-and ultimately limiting-hydrogen incoherent scattering background that has hampered such studies in the past. High quality neutron data can now be collected to near atomic resolution (-2.0 angstrom) for proteins of up to -50 kDa molecular weight using crystals of volume -0.1 mm(3) on the Laue diffractometer at ILL. The ability to flash-cool and collect high resolution neutron data from protein crystals at cryogenic temperature (15 K) has opened the way for kinetic crystallography on freeze trapped systems. Current instrument developments now promise to reduce crystal volume requirements by a further order of magnitude, making neutron protein crystallography a more accessible and routine technique.

In that context structural information from neutron data is complementary to that provided through X-ray diffraction. However, there are practical obstacles to overcome in fully exploiting the potential of neutron diffraction, i.e. low flux and weak scattering. Several approaches are available to overcome these obstacles and we have investigated the simplest: increasing the diffracting volume of the crystals. Volume is a quantifiable metric that is well suited for experimental design and optimization techniques. By using response surface methods we have optimized the xylose isomerase crystal volume, enabling neutron diffraction while we determined the crystallization parameters with a minimum of experiments. Our results suggest a systematic means of enabling neutron diffraction studies for a larger number of samples that require information on hydrogen position and/or protonation state.

TI Array comparative genomic hybridization in patients with congenital diaphragmatic hernia: mapping of four CDH-critical regions and sequencing of candidate genes at 15q26.1-15q26.2 SO EUROPEAN JOURNAL OF HUMAN GENETICS LA English DT Article DE congenital diaphragmatic hernia; array comparative genomic hybridization; microdeletion; 15q26 deletion syndrome ID WOLF-HIRSCHHORN-SYNDROME; FRYNS-SYNDROME; CYTOGENETIC CHARACTERIZATION; CHROMOSOME-ANOMALIES; DELETION; DNA; MALFORMATIONS; ASSOCIATION; POPULATION; DIAGNOSIS AB Congenital diaphragmatic hernia (CDH) is a common birth defect with a high mortality and morbidity. There have been few studies that have assessed copy number changes in CDH. We present array comparative genomic hybridization data for 29 CDH patients to identify and map chromosome aberrations in this disease. Three patients with 15q26.1-15q26.2 deletions had heterogeneous breakpoints that overlapped with the critical 4Mb region previously delineated for CDH, confirming 15q26.1-15q26.2 as a critical region for CDH. The three other most compelling CDH-critical regions for genomic deletions based on these data and a literature review are located at chromosomes 8p23.1, 4p16.3-4pter, and 1q41-1q42.1. Based on these recurrent deletions at 15q26.1-15q26.2, we hypothesized that loss-of-function mutations in a gene or genes from this region could cause CDH and sequenced six candidate genes from this region in more than 100 patients with CDH. For three of these genes (CHD2, ARRDC4, and RGMA), we identified missense changes and that were not identified in normal controls; however, none of these alterations appeared unambiguously causal with CDH. These data suggest that CDH caused by chromosome deletions at 15q26.2 may arise because of a contiguous gene deletion syndrome or may have a multifactorial etiology. In addition, there is evidence for substantial genetic heterogeneity in CDH and diaphragmatic hernias can be non-penetrant in patients who have deletions involving CDH-critical regions.

Methods: Antigen-mediated monoarthritis was induced in the right knee of 12 Sprague-Dawley rats. Six rats remained untreated and six rats were treated with cortisone. All rats received ex vivo fluorescent-labeled rat leukocytes. Optical images of both knees were acquired before and at 5 min, 1 h, 4 h, and 24 h after cell injection. Images were evaluated qualitatively and quantitatively by calculating signal intensity ratios between the right arthritic (A) and contralateral normal (N) knee. A/N ratios were tested for significant differences between baseline values and values after cell injection using a paired t test as well as between the untreated and cortisone-treated group using an unpaired t test. Synovial specimens were processed and evaluated for labeled cells with fluorescence microscopy. Results: At 4 h and 24 h p.i., the A/N ratios of untreated arthritic knees showed a significant signal increase compared with baseline values (p < 0.05) and a significant difference compared with A/N ratios of cortisone-treated animals (p < 0.05). Fluorescent microscopy confirmed the presence of labeled cells in the arthritic synovium. Conclusion: Inflammation in antigen-induced arthritis can be detected with ex vivo labeled allogenic leukocytes and optical imaging.
