The model is used to simulate chemical reactions between two initially distinct sample zones, referred to as "bands," that cross each other due to differences in electromigration velocities. The reaction is described in terms of a single step, reversible mechanism involving two reactants and one product. A parametric study is first conducted of the behavior of the species profiles, and results are interpreted in terms of the Damkohler number and of the ratios of the electromigration velocities of the reactant and product. Computed results are then used to explore the possibility of extracting forward and backward reaction rates based on time resolved observation of integral moments of species concentrations. In particular, it is shown that in the case of fast reactions, robust estimates can be obtained for high forward rates, but that small reverse rates may not be accurately observed.

Density-functional theory in various forms is used throughout. In the surface-related calculations, a 38-atom Ni cluster and several low-index Ni surfaces are investigated using pseudopotentials and plane-wave expansions. The energetic ordering of the sites for C atom adsorption is found to be the same, with the Ni(100) facet favored. The bulk diffusion coefficient of C in Ni as a function of cluster size and temperature is calculated from various molecular dynamics approaches. In another group of bulk-related calculations, Gaussian orbital basis sets are used to study a cluster or "flake" containing 14 C atoms. The flake is a segment of three hexagons from an "unrolled" carbon nanotube, with an armchair termination. The binding energies of C, Ni, Co, Fe, Cu, and Au atoms to it were calculated in an effort to gain insight into the mechanism for the high catalytic activity of Ni, Co, and Fe and the lack of it in Cu and Au. The binding energies of Cu and Au are about 1 eV less than those of the three catalytic elements. Similar methods are used to study the initial stages of nanotube growth within the context of classical nucleation theory. Finally, issues relating to the establishment of a fundamental catalytic mechanism are addressed. C1 Oak Ridge Natl Lab, Condensed Matter Sci Div, Oak Ridge, TN 37831 USA.

In the tip-growth mode, the sample is divided into three main regions, each of which can be further subdivided as required. In region 1, carbon is supplied to the catalytic particle from an ambient gas of carbon-containing compounds. The chemistry and thermodynamics of the decomposition of these compounds can be included in region 1, but the capability has not yet been implemented. The carbon diffuses through the catalytic particle in region 2 under concentration and temperature gradients and with a diffusion coefficient that can depend on both concentration and temperature. Region 3 consists of the interfacial region between the catalytic particle and the growing nanotube. Results to date demonstrate the key roles played by the size and shape of the catalytic particle in conjunction with the concentration and temperature gradients at the gas/solid interface and in region 2. Results also suggest how the growth of a single wall may interfere with, but not necessarily prevent, the growth of additional walls in a multi-walled nanotube. Again, the carbon concentration profile in the catalytic particle at the different growth sites is a key factor. C1 Oak Ridge Natl Lab, Condensed Matter Sci Div, Oak Ridge, TN 37831 USA.

Alloy surfaces have been characterized in ultra high vacuum (UHV) by Auger electron spectroscopy, low energy ion scattering spectroscopy (LEISS) and low energy electron diffraction (LEED). Clean Pt3Sn surfaces produce LEED patterns consistent with the surface composition, determined by LEISS, of similar to25 at% Sn. After UHV preparation and characterization crystals were transferred into the electrochemical environment where surface electrochemistry of CO was studied in-situ by Fourier transform infrared spectroscopy. In contrast to the Pt3Sn(111) surface, changes in band morphology (splitting of the band) and vibrational properties (increase in the frequency mode) are clearly absent on the Pt3Sn(110) surface. For the Pt3Sn(hkl)-CO interaction we found that in addition to electronic effects, other factors, such as surface structure and intermolecular repulsion between adsorbed CO species are responsible for high catalytic activity of these alloys. On Pt3Sn(hkl) surfaces continuous oxidative removal of CO from Pt sites starts at as low as E<0.1 V which is an important property for CO-tolerant catalysts.

Based on these fluxes, the diffusion coefficients, and the sums of heat of transport and enthalpy of solution for the gamma, gamma + zeta and delta + zeta phases in U-Pu-Zr were obtained. Using these data, the predicted concentration redistribution profiles are consistent with the measurements. The effect of minor actinide (Am and Np) addition was also examined. Am migration generally followed that of Zr with local precipitation, while Np behaved similarly to Pu. (C) 2004 Elsevier B.V. All rights reserved. C1 Argonne Natl Lab, Argonne, IL 60439 USA.

The purpose of this work was to determine the effect of natural aging on tensile properties of the WQ U-6%Nb alloy. The materials studied were hemispherical shells after 15 and 20 years in storage. The alloy was successfully tested in the original curved configuration, using the specially designed tensile test apparatus. Finite element analysis confirmed the validity of the test method. The results of the tensile tests clearly indicated that in the WQ condition, the material is changing and after 15 and 20 years, the yield strength exceeds the original maximum allowable specification. The fracture mode transitions from highly ductile, microvoid coalescence in new material to a mixed mode of shallow dimples and inclusion-induced voids in the naturally aged material.

Adipose mass increases in part through the recruitment and differentiation of an existing pool of preadipocytes (PA) into adipocytes (AD). Most studies investigating adipogenesis used primarily murine cell lines; much less is known about the relevant processes that occur in humans. Therefore, characterization of genes associated with adipocyte development is key to understanding the pathogenesis of obesity and developing treatments for this disorder. To address this issue, we performed large-scale analyses of human adipose gene expression using microarray technology. Differential gene expression between PA and AD was analyzed in 6 female patients using human cDNA microarray slides and data analyzed using the Stanford Microarray Database. Statistical analysis for the gene expression was performed using the SAS mixed models. Compared with PA, several genes involved in lipid metabolism were overexpressed in AD, including fatty acid binding protein, adipose differentiation-related protein, lipoprotein lipase, perilipin, and adipose most abundant transcript 1. Novel genes expressed in adipocytes included E2F5 transcriptional factor and SMARC (SWI/SNF-related, matrix associated, actin-dependent regulator of chromatin). PA predominantly expressed genes encoding extracellular matrix components such as fibronectin, matrix metalloprotein, and novel proteins such as lysyl oxidase. Despite the high differential expression of some of these genes, many did not differ significantly likely due to high variability and limited statistical power. A comprehensive list of differential gene expression is presented according to cellular function. In conclusion, these studies offer an overview of the gene expression profiles in PA and AD and identify new genes with potentially important functions in adipose tissue development and obesity that merit further investigation.

The purpose of this study was to assess the overall effect of the heterozygous deletion of Atp10c on obesity-related phenotypes and metabolic abnormalities in mice fed a high-fat diet. Heterozygous mice with maternal inheritance of Atp10c were compared with heterozygous mice with paternal inheritance of Atp10c and wild-type controls. Body weight, adiposity index, and plasma insulin, leptin and triglyceride concentrations were significantly greater in the mutants inheriting the deletion maternally compared with their sex- and age-matched control male mice fed a 10% fat (% energy) diet and female mice fed a 45% fat (% energy) diet. Glucose and insulin tolerance tests were performed after mice consumed the diets for 4 and 8 wk. Mutants had altered glucose tolerance and insulin response compared with controls, suggesting insulin resistance in both sexes. Mice were killed at 12 wk and routine gross and histological evaluations of the liver, pancreas, adipose tissue, and heart were performed. Histological evaluation showed micro- and macrovesicular lipid deposition within the hepatocytes that was more severe in the mutant mice than in age-matched controls. Although sex differences were observed, our data suggest that heterozygous deletion along with an unusual pattern of maternal inheritance of the chromosomal region containing the single gene, Atp10c, causes obesity, type 2 diabetes, and nonalcoholic fatty liverdisease in these mice.

We consider the electric-type (TMmn) wave with the lowest-order indices m = 0 and n = 1. For these waves we obtain exact analytical results for electromagnetic fields inside a conical waveguide with a loss-free dielectric core and perfectly conducting metallic walls. The contributions of different field components to the energy density distributions are explicitly expressed as functions of the radial and angular coordinates. We outline a technique for the evaluation of the optical fields in the near-field zone beyond the exit aperture. This provides tools for the calculation of the amplitude reflection coefficient taking into account the influence of a plane interface between the truncated cone and free space. Particular attention is paid to the calculations of the energy density at the exit aperture and the near-field transmission coefficient of an optical probe with a glass core. We present a detailed analysis of the optical transmission of such a waveguide as a function of the wavelength for large taper angles and various values of the aperture diameter reaching similar tolambda/40. The results obtained yield the range of the cone parameters and wavelengths in which one can achieve a high spatial resolution capability and sufficiently high transmission efficiency.

The best fits yielded the intrinsic Tafel slope in the range from -118 to -130 mV/dec, supporting single electron transfer in the rate-determining step with the corresponding transfer coefficients equal to 0.50 and 0.45, respectively. In addition to site blocking, a negative electronic effect on ORR kinetics was found for both OH and bisulfate with the effect of the latter being much stronger. The deviation of the apparent Tafel slope in HClO4 from its intrinsic value can be fully accounted for by the site blocking and electronic effects of adsorbed OH ions, which vary with coverage over the mixed kinetic-diffusion controlled region. For Pt nanoparticle catalysts, the apparent Tafel slope is similar to that for Pt(111) in HClO4 and the positive potential shift is mainly due to the increase in apparent exchange current as effective surface area increases.

The first of these supplements previously reported work at this laboratory, and the second consists of studies in an entirely new energy range. These experimental results are interpreted in terms of optical-statistical and coupled-channels models, including consideration of dispersive effects. Some basic and applied physical implications of these considerations are discussed. Comparisons are made with other regional models and with evaluated nuclear-data files used in applications.

They can melt at the equilibrium melting temperature, whereas crystallization needs considerable supercooling, even in the presence of crystal nuclei, making the overall phase transition irreversible. The same molecules with a metastable, chain-folded macroconformation may have a large amount of specific reversibility, that is, a fraction of the same polymer molecule that melts irreversibly may also show decoupled, reversible melting. The overall metastable, nanophase structure of such semicrystalline polymers may thus support local equilibria. The tool for the quantitative analysis is quasi-isothermal temperature-modulated calorimetry that can separate reversible from irreversible processes. A major review of the study of crystals of more than 20 polymers has been published. On the basis of this extensive body of information, a first discussion of decoupling of parts of macromolecules is attempted and linked to previous studies of phase equilibria.

MgBxPd3, MgBxPt3, CaBxPd3, MgCxRh3, LuCxRh3, and ZrCx,Rh-3 represent new intermetallic perovskites that form at a composition that is nominally stoichiometric (x - 1). ScBxPd3, YBxPd3, and NbBxRh3 are new single-phase perovskites that form only at a substoichiometric (x < 1) nominal composition. The variable boron content of AB(x)Pd(3) (A - Mg, Ca, Sc, Y) was studied using lattice parameter data from X-ray diffraction measurements. For A = Ca and Mg, the unit cell volume increases with increasing boron content for 0.25less than or equal toxless than or equal to1.0, while boron uptake is limited to 0less than or equal toxless than or equal to0.5 for A = Sc and Y. Neutron diffraction studies indicate that CaBxPd3 is not actually stoichiometric at a nominal composition of x = 1. Rather, saturation of the boron content occurs at CaB0.76Pd3. Evidence for superconductivity was found in samples of CaBxPd3 (x greater than or equal to 1) and NbBxRh3, but bulk analysis suggests that superconductivity may be attributed to minority phases.

The neutral layers in compounds 1 and 2 are isostructural with NPO2(IO3)(2).H2O and PuO2(IO3)(2).H2O, respectively. The Np and Pu centers are found in distorted pentagonal bipyramidal [AnO(7)] environments that are formed from the ligation of NpO22+ or PuO22+ cations by iodate anions. There are two crystallographically unique pyramidal iodate anions in 1 and 2. One of these anions utilizes all three oxygen atoms to simultaneously bridge three neptunyl or plutonyl units. The second anion only bridges two actinyl units and has a terminal oxo atom. The bridging of the actinyl cations by iodate anions creates neutral (2)(infinity)[AnO(2) (IO3)(3)] (An = Np, Pu) sheets that are separated by K+ cations, Cl- anions, and water molecules.

Using special synthesis techniques, we have extended the solubility limit of Ga3+ in the cubic perovskite phase to xapproximate to0.33. Higher Ga concentrations lead to mixed phases until a single-phase ordered double-perovskite structure is obtained at x = 0.5, i.e., Sr2MnGaO6-delta. In the cubic perovskite phase the maximum oxygen content is 3 - x/2, which corresponds to 100% Mn4+. All maximally oxygenated solid solution compounds are found to order antiferromagnetically, with the transition temperature linearly decreasing as Ga content increases. Reducing the oxygen content introduces frustration into the magnetic system and a spin-glass state is observed for SrMn0.7Ga0.3O2.5 below 30 K. The brownmillerite phase at low oxygen content, Sr2MnGaO5, is found to have Icmm crystallographic symmetry. At 12 K its magnetic structure is found to order in the magnetic symmetry corresponding to a G-type antiferromagnetic structure of Mn3+ ions. At higher oxygen content, Sr2MnGaO5.5 is found to have Cmmm crystallographic symmetry with disordered oxygen vacancies. At 12 K two competing long-range magnetic structures are found for the Mn4+ sublattice having C(I)m'm'm symmetry (G-type), and C(p)m'm'm symmetry (C-type), together with a G-type short-range magnetic correlations.

One technique currently used to bring Fermi gases in the degenerate regime is sympathetic cooling through a reservoir made of an ultracold Bose gas. We discuss a proposal for trapping and cooling of two-species Fermi-Bose mixtures into optical dipole traps made from combinations of laser beams having two different wavelengths. In these bichromatic traps it is possible, by a proper choice of the relative laser powers, to selectively trap the two species in such a way that fermions experience a stronger confinement than bosons. As a consequence, a deep Fermi degeneracy can be reached having at the same time a softer degenerate regime for the Bose gas. This leads to an increase in the sympathetic cooling efficiency and allows for higher precision thermometry of the Fermi - Bose mixture.

Although perceived by many in signal processing as simply an application of matched-filter theory, a T/R receiver offers an interesting solution to the communications problem for a reverberant channel. In this paper, the performance of various realizations of the T/R receiver for an acoustic communications experiment in air is described along with its associated processing. The experiment is developed to evaluate the performance of point-to-point T/R receivers designed to extract a transmitted information sequence propagating in a highly reverberant environment. It is demonstrated that T/R receivers are capable of extracting the transmitted coded sequence from noisy microphone sensor measurements with zero-symbol error. The processing required to validate these experimental results is discussed. These results are also compared with those produced by an equivalent linear equalizer or inverse filter, which provides the optimal solution when it incorporates all of the reverberations.

The effects of bombardment from accelerated argon and oxygen ions on the properties of SBTN thin films were investigated. It was found that the argon ion bombardment could decrease the crystallization temperature owing to the increase of internal energy of the films. Also, the oxygen vacancies at the interface between the SBTN film and platinum bottom electrode or at grain boundaries in the film were passivated through the oxygen ion treatment, resulting in the improved electrical properties. By optimizing the process parameters and using bombardment of accelerated argon and oxygen ions, SBTN films with good ferroelectric and electrical properties could be obtained, at a temperature as low as 650degreesC.

These JFDs were found to be tilted, with the tilt a function of both height and boundary layer dynamics. These distributions are also skewed and more peaked than a joint Gaussian distribution. Three different methods are used to generate joint probability density functions (JPDFs) that approximate observed JFDs. Two classical methods, one based on a Gaussian fit and another based on surface-layer processes, are reviewed. A new method is devised, which treats the observed JFD as a mixing diagram. In the absence of advection, the only source regions for air in the mixing diagram are the surface and the entrainment zone. Thus, the tilt of the JFD can be explained by various mixtures from these two source regions. Methods that can be used to parameterize the mixing JPDF are presented. The primary advantage of this method is that the tilt is determined explicitly from properties of the surface, mixed layer, and entrainment zone. Similarity methods are used to parameterize all variables needed by the Gaussian model. The Bowen ratio and the total energy input are used to parameterize the tilt of the surface energy budget JPDF, while similarity methods are used to define the spread of the JPDF along the two axes. Relationships between the surface and mixed layer, and the mixed layer and free atmosphere are used to tilt the mixing diagram JPDF, while similarity methods are used to estimate the spread of the JPDF. The parameterizations are developed using a "calibration'' subset of data acquired during BLX96. A "verification'' subset of data, also acquired during BLX96, is used to show that the parameterized mixing diagram method is superior to the other two methods, because it has either a smaller error or is less sensitive to the value of the correlation between theta and r.

The electronic structure is obtained with the local spin-density approximation (LSDA), as well as with a generalization of the LSDA+U method which takes into account that in the presence of spin-orbit coupling, the occupation matrix of localized electrons becomes nondiagonal in the spin indices. The origin of the XMCD spectra in the compounds is examined. (C) 2004 American Institute of Physics. C1 Iowa State Univ, Ames Lab, Ames, IA 50011 USA. Kiev Met Phys Inst, UA-03142 Kiev, Ukraine.

The composition of the glasses in the SiO2-Na2O-K2O-MgO-CaO-P2O5 system has been tailored to match the thermal expansion of the alloys. The optimum glass composition and firing conditions (temperature and time) needed to fabricate homogeneous coatings with good adhesion to the alloy were determined. The final coating thickness ranged between 40 and 60 pro. Coatings fired under the optimum conditions do not delaminate during indentation tests of adhesion. Excellent adhesion to the alloy has been achieved through the formation of 150 mu thick interfacial layers (CrOx). The silicate glass can be successfully coated to Co-Cr alloy and formed hydroxyapatite on the glass Surface when immersed in a simulated body fluid (SBF) for 30 days.

Previous studies have indicated that subsurface property variations can often be characterized by fractional Brownian motion (fBm) or ( truncated) fractional Levy motion (fLm). Because Levy-stable distributions have many novel and often unfamiliar properties, studies on generating fLm distributions are rare in the literature. In this study, we generalize a relatively simple and computationally efficient successive random additions (SRA) algorithm, originally developed for generating Gaussian fractals, to simulate fLm distributions. We also propose an additional important step in response to continued observations that the traditional SRA algorithm often generates fractal distributions having poor scaling and correlation properties. Finally, the generalized and modified SRA algorithm is validated through numerical tests. C1 Univ Calif Berkeley, Lawrence Berkeley Lab, Div Earth Sci, Berkeley, CA 94720 USA.

This transformation can be performed by applying different elimination techniques that may lead to varying costs for computing F'. This paper introduces face elimination as the basic technique for accumulating Jacobian matrices by using a minimal number of arithmetic operations. Its Superiority over both edge and vertex elimination methods is shown. The intention is to establish the conceptual basis for the ongoing development of algorithms for optimizing the computation of Jacobian matrices.

A multicompartmental model was formulated and fitted to the data by standard nonlinear regression using the Simulation, Analysis and Modeling (SAAM 11) program. Smaller sized LDL particles (251 to 257 A) demonstrated a significantly slower fractional catabolic rate (FCR) (0.050 +/- 0.045 h(-1)) compared with particles of larger size (262 to 265 Angstrom) (0.134 +/- -0.015 h(-1), P < .03), and there was a significant correlation between FCR and the peak LDL diameter of the injected fractions (R-2 = .71, P < .034). The sum of the equilibration parameters, k(2,1) and k(1,2), for smaller LDL (0.255 h(-1) and 0.105 h(-1), respectively) was significantly smaller than that for larger LDL (0.277 h(-1) and 0.248 h(-1), respectively; P < .01), indicative of slower intravascular-extravascular exchange for smaller LDL. Therefore in this mouse model, smaller LDL particles are cleared more slowly from plasma than larger LDL and are exchanged more slowly with the extravascular space. This might be due to compositional or structural features of smaller LDL that lead to retarded clearance. (C) 2004 Elsevier Inc. All rights reserved.

The name Park Forest, for the village that is at the center of the strewnfield, has been approved by the nomenclature committee of the Meteoritical Society. Satellite data indicate that the bolide traveled from the southwest toward the northeast. The strewnfield has a southeast-northwest trend; however, this is probably due to the effects of strong westerly winds at high altitudes. Its very low Co-56 and very high Co-60 activities indicate that Park Forest had a preatmospheric mass that was at least similar to900 kg and could have been as large as similar to7 x 10(3) kg, of which only similar to30 kg have been recovered. The average compositions of olivine and low-Ca pyroxene, Fa(24.7 +/- 1.1) and FS20.8 +/- 0.7, respectively, and its bulk oxygen isotopic composition, delta(18)O = +4.68parts per thousand, delta(17)O = +3.44parts per thousand, show that Park Forest is an L chondrite. The ferromagnesian minerals are well equilibrated, chondrules are easily recognized, and maskelynite is mostly less than or equal to50 mum across. Based on these observations, we classify Park Forest as type 5. The meteorite has been strongly shocked, and based on the presence of maskelynite, mosaicism and planar deformation features in olivine, undulatory extinction in pyroxene, and glassy veins, the shock stage is S5. The meteorite is a monomict breccia, consisting of light-colored, angular to rounded clasts in a very dark host. The light and dark lithologies have essentially identical mineral and oxygen isotopic compositions. Their striking difference in appearance is due to the presence of a fine, pervasive network of sulfide veins in the dark lithology, resulting in very short optical path lengths. The dark lithology probably formed from the light lithology in an impact that formed a sulfide-rich melt and injected it into cracks. C1 Univ Chicago, Dept Geophys Sci, Chicago, IL 60637 USA.

The main objectives were to study the combined effects of changes of terrain height and changes of width in altering the flow characteristics, to investigate the coupling of the gap flow to the flow aloft, and to provide high-density measurements in the along- and cross-gap directions. Gap flows occurred during one third of the 70-day SOP, a frequency above the long term average. Gap flows took place with and without accompanying cross-barrier flow and with and without a capping inversion. A case study demonstrates the hydraulic jump-like features that occurred in gap flow on 30 October 1999 and illustrates the types of data available for further analyses.

Here we describe the use of these devices to monitor the groundwater microbial community dynamics during field bioremediation experiments at the U.S. Department of Energy Natural and Accelerated Bloremediation Research Program's Field Research Center at the Oak Ridge National Laboratory. During the 6-week deployment, microbial biofilms colonized glass wool and bead internal surfaces. Changes in viable biomass, community composition, metabolic status, and respiratory state were reflected in sampler composition, type of donor, and groundwater PH. Biofilms that formed on Bio-Sep beads had 2-13 times greater viable biomass; however, the bead communities were less metabolically active [higher cyclopropane/monoenoic phospholipid fatty acid (PLFA) ratios] and had a lower aerobic respiratory state (lower total respiratory quinone/ PLFA ratio and ubiquinone/menaquin one ratio) than the biofilms formed on glass wool. Anaerobic growth in these systems was characterized by plasmalogen phospholipids and was greater in the wells that received electron donor additions. Partial 16S rDNA sequences indicated that Geobacter and nitrate-reducing organisms were induced by the acetate, ethanol, or glucose additions. DNA and lipid biomarkers were extracted and recovered without the complications that commonly plague sediment samples due to the presence of clay or dissolved organic matter. Although microbial community composition in the groundwater or adjacent sediments may differ from those formed on down-well biofilm samplers, the metabolic activity responses of the biofilms to modifications in groundwater geochemistry record the responses of the microbial community to biostimulation while providing integrative sampling and ease of recovery for biomarker analysis.

The benefits are especially pronounced for low voltage (less than or equal to5 kV) X-ray microanalysis in the field emission scanning electron microscope (FE-SEM) where the high energy resolution of the mu-cal EDS minimizes the peak overlaps among the myriad of K, L, M and N lines in the 0-5 keV energy range. The availability of L- and M-shell X-ray lines for microanalysis somewhat offsets the absence of X-ray lines traditionally used above 5 keV energy. The benefits and challenges of the mu-cal EDS will be discussed, including P/B ratio for characteristic X-rays, collection angle, count rate capability and the impact of polycapillary X-ray optics on microanalysis.

The growth rate of the oxide was investigated and found to depend heavily on the germanium and carbon concentrations. MOS capacitors were fabricated with the resulting oxide and electrical characterization was done. The SiGeC MOS capacitors proved to have high leakage current through the gate oxide. The leakage current was found to be highly dependent on carbon concentration, and to a lesser degree, on germanium concentration, as well. Fixed oxide charge and interface state density were found to increase by a factor of ten over photo-oxidized silicon. (C) 2004 Published by Elsevier B.V.

The total dose response of Sol devices is more complex than for bulk-silicon devices due to the buried oxide. Radiation-induced trapped charge in the buried oxide can increase the leakage current of partially-depleted transistors and decrease the threshold voltage and increase the leakage current of fully-depleted transistors. We review process and design techniques that have been developed to reduce the net amount of radiation-induced positive charge trapped in the buried oxide or to mitigate the effects of trapped charge in the buried oxide, respectively. We also compare the total dose response of devices operated in single-gate (SG) and double-gate (DG) mode as a function of silicon film thickness. DG-MOSFETs are systematically less sensitive to radiation-induced trapped charge and interface trap. (C) 2004 Elsevier B.V. All rights reserved.

These can be used as an effective method for total-dose hardening buried oxides in SOI devices. In this work, we show that implanting buried oxides can also create thermally activated metastable electron traps near the top Si/SiO2 border. These metastable electron traps can produce significant bias instabilities in the back-gate transistor characteristics and lead to threshold voltage instabilities in fully-depleted devices.

The total dose radiation responses of several near and long term alternative gate dielectrics to SiO(2) are discussed. Radiation results are presented for nitrided oxides, which show no change in interface trap density with dose and oxide trapped charge densities comparable to ultra thin thermal oxides. For aluminum oxide and hafnium oxide gate dielectric stacks, the density of oxide trapped charge is shown to depend strongly on the film thickness and processing conditions. The alternative gate dielectrics discussed here are shown to have effective trapping efficiencies that are up to similar to15 to 20 times larger than thermal SiO(2) of equivalent electrical thickness. A discussion of single event effects in devices and ICs is also provided. It is shown that some alternative gate dielectrics exhibit excellent tolerance to heavy ion induced gate dielectric breakdown. However, it is not yet known how irradiation with energetic particles will affect the long term reliability of MOS devices with high-kappa gate dielectrics in a space environment.

These methods are marginally effective and are not well suited for implantation due to the inability to miniaturize the associated technologies. Consequently, no standardized techniques exist for real-time, continuous monitoring of organ perfusion following transplantation. In this paper, a brief overview of the relevant clinical techniques employed for regional tissue perfusion assessment is given with particular emphasis on post-surgical monitoring of transplanted organs. The ideal characteristics for a perfusion monitoring system are discussed and the development of a new, completely implanted local tissue monitoring system is summarized. In vivo and in vitro data are presented that establish the efficacy of this new technology, which is a photonics-based sensor system uniquely suited for continuous tissue monitoring and real-time data reporting. The suitablity of this sensor technology for miniaturization, which enables implantation for monitoring localized tissue perfusion, is discussed.

The methodologies used were 1) literature search for proteins reported to occur in plasma or serum; 2) multidimensional chromatography of proteins followed by two-dimensional electrophoresis and mass spectroscopy ( MS) identification of resolved proteins; 3) tryptic digestion and multidimensional chromatography of peptides followed by MS identification; and 4) tryptic digestion and multidimensional chromatography of peptides from low-molecular-mass plasma components followed by MS identification. Of 1,175 nonredundant gene products, 195 were included in more than one of the four input datasets. Only 46 appeared in all four. Predictions of signal sequence and transmembrane domain occurrence, as well as Genome Ontology annotation assignments, allowed characterization of the nonredundant list and comparison of the data sources. The "nonproteomic" literature ( 468 input proteins) is strongly biased toward signal sequence-containing extracellular proteins, while the three proteomics methods showed a much higher representation of cellular proteins, including nuclear, cytoplasmic, and kinesin complex proteins. Cytokines and protein hormones were almost completely absent from the proteomics data ( presumably due to low abundance), while categories like DNA-binding proteins were almost entirely absent from the literature data ( perhaps unexpected and therefore not sought). Most major categories of proteins in the human proteome are represented in plasma, with the distribution at successively deeper layers shifting from mostly extracellular to a distribution more like the whole ( primarily cellular) proteome. The resulting nonredundant list confirms the presence of a number of interesting candidate marker proteins in plasma and serum. C1 Plasma Proteome Inst, Washington, DC 20009 USA.

The results are compared with the classical theory predictions based on the solution to the Poisson-Boltzmann equation. We find that despite some of the limitations in the Poisson-Boltzmann equation, such as assumption of the Boltzmann distribution for the ions, the classical theory captures the general trend of the variations of the osmotic flow with channel width, as characterized by the mobility of the fluid in channels between similar to10 and 120 nm at moderate to low ion concentration. At moderate concentration (corresponding to relatively low surface potential), the classical theory is almost quantitative. The theory and simulation show more disagreement at low concentration, primarily caused by the high surface potential where the assumption of Boltzmann distribution becomes inaccurate. We discuss the limitations of the Poisson-Boltzmann equation as applied to the nanoscale channels. C1 Univ Tennessee, Dept Chem Engn, Knoxville, TN 37996 USA.

Model fits require only a power law with Galactic absorption in each case; additional intrinsic absorption is also needed for [HB89] 0438-436 and RX J122135.6+280613. The spectra are hard (Gamma similar to 1.7 for [HB89] 0438-436, [HB89] 2000-330 and similar to1.4 for RX J122135.6+280613), with the exception of [SP89] 1107+487, which is softer (Gamma similar to 2.0); the combined Galactic and intrinsic absorption of lower-energy X-rays in the last of the sources is much less significant than in the other three. The two intrinsically unabsorbed sources have greater optical fluxes relative to the X-ray contributions at the observed energies. While there is no need to include reflection or iron line components in the models, our derived upper limits (99 per cent confidence) on these parameters are not stringent; the absence of these features, if confirmed, may be explained in terms of the high power-law contribution and/or a potentially lower albedo as a result of the low disc temperature. However, we note that the power-law spectrum can be produced via mechanisms other than the Comptonization of accretion disc emission by a corona; given that all four of these quasars are radio sources at some level, we should also consider the possibility that the X-ray emission originates, at least partially, in a jet.

They exhibited the size-selective photoregulated mass transport of two ferrocene-based molecular probes through the membrane to the electrode surface as determined using a chronoamperometry technique. The measured oxidative current increased and decreased in response to alternating UV and visible light exposure correlating strongly with the photoisomerization state of the azobenzene ligands. This indicates that the optically switchable conformation (trans or cis) of azobenzene ligands controls the effective pore size and, correspondingly, transport behavior on the nanoscale.

It relies on high temperature decomposition of tetraethylgermane (TEG) in organic solvents. The presence of pure germanium with diamond structure is unambiguously attested by powder XRD measurements. Low-resolution TEM indicates that the particles are between similar to5 to 30 nm in size, depending on the synthesis conditions. The as-synthesized Ge powders can be stored in air for months and no oxidation occurs. The Ge powders are sparingly soluble in conventional solvents because Ge nanocrystals are likely embedded in a matrix composed mainly of C=C, C-C, and C-H bonds. The presence of residual organic byproducts impedes probing of the optical properties of the dots. Also, we discuss drawbacks and open challenges in high-temperature solution synthesis of Ge nanocrystals that could also be faced in the synthesis of Si nanocrystals. Overall, our results call for a cautious interpretation of reported optical properties of Ge and Si nanocrystals obtained by high-temperature solution methods.

These structures provide urgently needed points of reference for molecular dynamics simulations and serve as models of transient and disordered biological nanowater. We show here that applying simultaneous pressure and temperature using a hydrothermal diamond anvil cell permits the intermolecular manipulation of water wires due to changes in the geometry of the host scaffolding and the enclosed hydrogen bonded water. During this process the ordered water wires formed under pressure change their direction depending on the temperature. This provides the opportunity to study the dynamics of confined water at the nanoscale by temperature and/or pressure-jump experiments. Our studies indicate that confined water responds differently to pressure and temperature than does bulk water. C1 Brookhaven Natl Lab, Dept Phys, Upton, NY 11973 USA.

We apply a simple nonlinear dynamical model to a finite segment of the bacteriophage T7 core promoter DNA. The temperature dependence of the dynamic structure factor is investigated. A distinct feature is identified and attributed to coherent localized thermal openings (hot-spots) due to nonlinearity combined with sequence specificity. We present the variation of the position and the width of the corresponding dynamic structure factor feature with temperature. Finally, a strong deviation of the Debye-Waller factor from the usual harmonic form is evaluated. C1 Los Alamos Natl Lab, Div Theoret, Los Alamos, NM 87545 USA.

The Raman spectroscopy shows that the as-grown BxCyNz nanotubes are radially phase separated into BN shells and carbon shells. The photoluminescence decay process is characterized by two time constants that are attributed to intra- and inter-BN sheet charge recombination, respectively. A comparison of the photoluminescence of BN nanotubes to that of hexagonal BN is consistent with the existence of a spatially indirect band gap in multiwalled BN nanotubes as predicted by theory.

PREDICTION; ANIMAL-MODEL AB The laboratory rat (Rattus norvegicus) is an indispensable tool in experimental medicine and drug development, having made inestimable contributions to human health. We report here the genome sequence of the Brown Norway (BN) rat strain. The sequence represents a high-quality 'draft' covering over 90% of the genome. The BN rat sequence is the third complete mammalian genome to be deciphered, and three-way comparisons with the human and mouse genomes resolve details of mammalian evolution. This first comprehensive analysis includes genes and proteins and their relation to human disease, repeated sequences, comparative genome-wide studies of mammalian orthologous chromosomal regions and rearrangement breakpoints, reconstruction of ancestral karyotypes and the events leading to existing species, rates of variation, and lineage-specific and lineage-independent evolutionary events such as expansion of gene families, orthology relations and protein evolution.

The large clustered gene families, corresponding high G+C content, CpG islands and density of repetitive DNA indicate a chromosome rich in biological and evolutionary significance. Here we describe 55.8 million base pairs of highly accurate finished sequence representing 99.9% of the euchromatin portion of the chromosome. Manual curation of gene loci reveals 1,461 protein-coding genes and 321 pseudogenes. Among these are genes directly implicated in mendelian disorders, including familial hypercholesterolaemia and insulin-resistant diabetes. Nearly one-quarter of these genes belong to tandemly arranged families, encompassing more than 25% of the chromosome. Comparative analyses show a fascinating picture of conservation and divergence, revealing large blocks of gene orthology with rodents, scattered regions with more recent gene family expansions and deletions, and segments of coding and non-coding conservation with the distant fish species Takifugu.

It also conducts heat even more effectively than copper, and can withstand very high electric fields(1). With these physical properties, diamond is attractive for electronic applications(2), particularly when charge carriers are introduced (by chemical doping) into the system. Boron has one less electron than carbon and, because of its small atomic radius, boron is relatively easily incorporated into diamond(3); as boron acts as a charge acceptor, the resulting diamond is effectively hole-doped. Here we report the discovery of superconductivity in boron-doped diamond synthesized at high pressure (nearly 100,000 atmospheres) and temperature (2,500-2,800 K). Electrical resistivity, magnetic susceptibility, specific heat and field-dependent resistance measurements show that boron-doped diamond is a bulk, type-II superconductor below the superconducting transition temperature T(c)approximate to4 K; superconductivity survives in a magnetic field up to H-c2(0)greater than or equal to3.5 T. The discovery of superconductivity in diamond-structured carbon suggests that Si and Ge, which also form in the diamond structure, may similarly exhibit superconductivity under the appropriate conditions.

The stroke size has been measured previously using isolated myosin II molecules at low load, with rather variable results(1-4), but not at the higher loads that the motor works against during muscle contraction. Here we used a novel X-ray-interference technique(5,6) to measure the working stroke of myosin II at constant load(7) in an intact muscle cell, preserving the native structure and function of the motor. We show that the stroke is smaller and slower at higher load. The stroke size at low load is likely to be set by a structural limit(8,9); at higher loads, the motor detaches from actin before reaching this limit. The load dependence of the myosin II stroke is the primary molecular determinant of the mechanical performance and efficiency of skeletal muscle.

It is not clear how this differential response to TGF-beta is specified. Smad proteins are critical mediators of TGF-beta signalling. After stimulation by TGF-beta, Smad2 and Smad3 become phosphorylated by the activated TGF-beta receptor kinases, oligomerize with Smad4, translocate to the nucleus and regulate the expression of TGF-beta target genes(1-5). Here we report that the sensitivity to TGF-beta-induced apoptosis is regulated by crosstalk between the Akt/PKB serine/threonine kinase and Smad3 through a mechanism that is independent of Akt kinase activity. Akt interacts directly with unphosphorylated Smad3 to sequester it outside the nucleus, preventing its phosphorylation and nuclear translocation. This results in inhibition of Smad3-mediated transcription and apoptosis. Furthermore, the ratio of Smad3 to Akt correlates with the sensitivity of cells to TGF-beta-induced apoptosis. Alteration of this ratio changes the apoptotic, but not the growth-inhibitory, responses of cells to TGF-beta. These findings identify an important determinant of sensitivity to TGF-beta-induced apoptosis that involves crosstalk between the TGF-beta and phosphatidylinositol-3-OH kinase (PI(3)K) pathways.

Here we show that disruption of the gene Ppm1d encoding Wip1 phosphatase activated the p53 and p16 ( also called Ink4a) p19 ( also called ARF) pathways through p38 MAPK signaling and suppressed in vitro transformation of mouse embryo fibroblasts ( MEFs) by oncogenes. Disruption of the gene Cdkn2a ( encoding p16 and p19), but not of Trp53 ( encoding p53), reconstituted cell transformation in Ppm1d - null MEFs. In vivo, deletion of Ppm1d in mice bearing mouse mammary tumor virus ( MMTV) promoter driven oncogenes Erbb2 ( also called c - neu) or Hras1 impaired mammary carcinogenesis, whereas reduced expression of p16 and p19 by methylation-induced silencing or inactivation of p38 MAPK correlated with tumor appearance. We conclude that inactivation or depletion of the Wip1 phosphatase with resultant p38 MAPK activation suppresses tumor appearance by modulating the Cdkn2a tumor-suppressor locus.

We previously identified a locus linked to FCHL on 1q21-q23 in Finnish families with the disease(3). This region has also been linked to FCHL in families from other populations(4-6) as well as to type 2 diabetes mellitus(7-12). These clinical entities have several overlapping phenotypic features, raising the possibility that the same gene may underlie the obtained linkage results. Here, we show that the human gene encoding thioredoxin interacting protein (TXNIP) on 1q, which underlies combined hyperlipidemia in mice(13), is not associated with FCHL. We show that FCHL is linked and associated with the gene encoding upstream transcription factor 1 (USF1) in 60 extended families with FCHL, including 721 genotyped individuals (P = 0.00002), especially in males with high triglycerides (P = 0.0000009). Expression profiles in fat biopsy samples from individuals with FCHL seemed to differ depending on their carrier status for the associated USF1 haplotype. USF1 encodes a transcription factor known to regulate several genes of glucose and lipid metabolism(14-17).

We sought to replicate these observations and further identify peripheral vascular components of AD pathology. Methods: Methacholine chloride (MCh), acetylcholine chloride (ACh), and sodium nitroprusside (SNP) were applied iontophoretically to forearm skin. Laser Doppler imaging of treated areas yielded total perfusion response values. Results: Response to MCh was enhanced 78% (P = 0.003) in AD subjects under therapy with the acetylcholinesterase inhibitor (AChEI) donepezil (N = 9), relative to age- and sex-matched controls (N = 12). Significant increases in perfusion were also observed after application of ACh (68%, P = 0.03) and SNP (46%, P = 0.04). Conclusions: A previous study reported attenuated response to ACh in AD. Paradoxically, we observed a substantially enhanced response that is likely a consequence of donepezil therapy. The increased response to the endothelium-independent vasodilator SNP indicates improved general vasodilatory response, perhaps due to preservation of endogenous ACh by donepezil. Cerebral perfusion in response to functional activation may be improved in this way, suggesting a secondary therapeutic mode of donepezil. (C) 2003 Elsevier Inc. All rights reserved.

Here we assess the response of the human brain to the presentation of appetitive food stimuli during food presentation using PET and FDG. Method. Metabolic changes in response to food presentation were done in 12 healthy normal body weight subjects who were food deprived before the study. Results: Food presentation significantly increased metabolism in the whole brain (24%, P < 0.01) and these changes were largest in superior temporal, anterior insula, and orbitofrontal cortices. The increases in the right orbitofrontal cortex were the ones that correlated significantly with the increases in self-reports of hunger and desire for food. Discussion: The marked increase in brain metabolism by the presentation of food provides evidence of the high sensitivity of the human brain to food stimuli. This high sensitivity coupled with the ubiquitousness of food stimuli in the environment is likely to contribute to the epidemic of obesity. In particular, the activation of the right orbitofrontal cortex, a brain region involved with drive, may underlie the motivation to procure food, which may be subjectively experienced as "desire for food" and "hunger" when exposed to food stimuli.

Prediction is usually based on nondestructive evaluation (NDE) of cracks. NDE often reveals two neighboring cracks. If the cracks interact, the tube pressure under which the ligament between the two cracks fails could be much lower than the critical burst pressure of an individual equivalent crack. The ability to accurately predict the ligament failure pressure, called "coalescence pressure," is important. The failure criterion was established by nonlinear finite element model (FEM) analyses of coalescence of two 100% through-wall collinear cracks. The ligament failure is precipitated by local instability of the ligament under plane strain conditions. As a result of this local instability, the ligament thickness in the radial direction decreases abruptly with pressure. Good correlation of FEM analysis results with experimental data obtained at Argonne National Laboratory's Energy Technology Division demonstrated that nonlinear FEM analyses are capable of predicting the coalescence pressure accurately for 100% through-wall cracks. This failure criterion and FEA work have been extended to axial cracks of varying ligament width, crack length, and cases where cracks are offset by axial or circumferential ligaments.

Analysis of the dynamic behavior of the ADTF has been carried out in the frame of a bilateral collaboration between the Forschungszentrum Karlsruhe and the Argonne National Laboratory (ANL). In the present study five different system configurations with various types of fuel and different types of coolant have been taken into consideration. In the systems with sodium as coolant, the transient behavior under the unprotected loss-of-flow scenario shows the most serious safety concern. As long as the external source is switched on, loss-of-flow will lead to an overheating of coolant, cladding and fuel. Boiling of coolant, cladding failure and molten fuel injection take place just in several seconds after the coast-down of the pump. Safety measures have to be designed for switching off the proton beam. In the system with liquid lead-bismuth eutectic (LBE) as coolant, the buoyancy effect is much stronger. Due to its high boiling point, coolant boiling and, subsequently, flow oscillation in fuel assemblies can be avoided. By a proper design of the heat removal system, the buoyancy-driven convection would provide a sufficiently high cooling capability of the reactor core, to keep the integrity of the fuel pins.

'Flow reversal' was found near the HFS and LFS separatrix of the main plasma for the ion delB drift direction towards the divertor. 'Flow reversal' at the main SOL was reproduced numerically using the UEDGE code with the plasma drifts included although Mach numbers in measurements were greater than those obtained numerically. Particle fluxes towards the HFS and LFS divertors produced by the parallel SOL flow and E-r x B drift flow were evaluated from the measured profiles of Mach numbers, the density and the radial electric field. The drift flux in the private flux region was also evaluated, and it was found that its contribution to the HFS-enhanced asymmetry of the divertor particle flux was larger than the ion flux from the HFS SOL. The ion flux for the intense gas puff and divertor pump ('puff and pump') was investigated, and it was found that both the Mach number and density were enhanced, in particular, at the HFS. Ion flux at the HFS SOL can be enhanced so as to become larger than the drift flux in the private flux region. C1 Japan Atom Energy Res Inst, Naka, Ibaraki 3110193, Japan.

From a database analysis, it is found that the energy confinement time in NBI heated plasmas with either L- or H-modes edge is up to 2.5 times the values predicted by theITER97L scaling. A high power NBI heated H-mode discharge is discussed in detail. TRANSP calculations based on the kinetic profile measurements reproduce well the magnetically determined stored energy, but overestimate the measured neutron rate by 30%. Power balance calculations reveal that the ion thermal transport is above or near neoclassical levels, and significantly below the electron thermal transport, which constitutes the main power loss channel. Perturbative impurity injection techniques indicate the particle diffusivity is slightly above the neoclassical level in discharges with L-mode edge. High-harmonic fast-wave (HHFW) bulk electron heating is described and thermal transport is discussed. Thermal ion transport is found to be above the neoclassical level, and thermal electron transport remains the main loss mechanism. Evidence of an electron thermal internal transport barrier obtained with HHFW heating is presented. A description of H-mode discharges obtained during HHFW heating is made.

NSTX has a major radius R-0 = 0.86 m, a midplane half-width of 0.7 m, and an on-axis vacuum toroidal field B-0 less than or equal to 0.6 T and has reached a plasma current I-P 1.5 MA. Experiments have established the wall-stabilized MHD operating space of the machine. The maximum beta(t) and beta(N) have reached 35% and 6.5%, respectively, with beta(N) reaching 9.5l(i). Collapses in plasma toroidal rotation and beta(t) have been correlated with violation of the n = 1 ideal MHD beta limit, beta(N no-wall), computed by the DCON stability code using time-evolving EFIT reconstructions of experimental discharges. The resistive wall mode (RWM) was observed over a wide range of beta(N) when beta(N) no-wall was exceeded. Plasma toroidal rotation damping during the RWM was rapid and global. Damping rates were more than five times larger than caused by low toroidal mode number rotating modes alone, which displayed a slower, diffusive rotation damping away from the rational surface. The rotation damping rate and dynamics depend on the applied toroidal field and the computed minimum value of the safety factor. The computed RWM perturbed field structure from experimental plasma reconstructions has been input to the VALEN feedback analysis code for quantitative comparison of experimental and theoretical RWM growth rates and to analyse the effectiveness of various active feedback stabilization designs. The computed RWM n = 1 mode growth rate, which depends on plasma equilibrium parameters such as PN and pressure profile peaking, agrees well with experimental growth rates in different operating regimes. Increasing beta(N) in the ST initially improves mode coupling to the stabilizing wall; however, at the highest beta(N) values reached, the ideal with-wall beta limit, beta(N wall), is approached, the effectiveness of the passive stabilizing plates is reduced, and the computed RWM growth rate approaches ideal MHD growth rates. Several active mode control designs were considered and evaluated. The most effective configuration is computed to provide stabilization at beta(N) up to 94% of the ideal with-wall limit.

E-158 will measure the right-left cross-section asymmetry, A(LR)(Moller), in the elastic scattering of a 45-GeV polarized electron beam from unpolarized electrons in a liquid hydrogen target. E-158 plans to measure the expected Standard Model asymmetry of similar to10(-7) to an accuracy of better than 10(-8). To make this measurement, the photoemission-based polarized electron source requires an intense circularly polarized laser beam and the ability to quickly switch between right- and left-helicity polarization states with minimal right-left helicity-correlated asymmetries in the resulting beam parameters (intensity, position, angle, spot size, and energy), (beam)A(LR)'s. This laser beam is produced by a unique SLAG designed flashlamp-pumped Ti:Sapphire laser and is directed through a carefully designed set of polarization optics. We analyze the transport of nearly circularly polarized light through the optical system and identify several mechanisms that generate (beam)A(LR)'s. We show that the dominant effects depend linearly on particular polarization phase shifts in the optical system. We present the laser system design and a discussion of the suppression and control of (beam)A(LR)'s. We also present results on beam performance from engineering and physics runs for E-158.

Novel design features provide the potential for neutron yields as high as 10(14) n/s in a compact geometry. Such high neutron yields make the neutron generator applicable to the production of thermal or cold neutrons for neutron scattering experiments. This paper describes a scheme to simulate a neutron scattering setup and to estimate neutron flux and resolution with the particle transport code MCNP. For an estimated resolution of 1-4%, depending on the scattered angle and neutron energy, a thermal neutron flux at the sample position of 7 x 10(5) n/cm(2) s has been estimated. Such a neutron generator is particularly suitable for cold neutron scattering experiments due to relatively longer flight times. (C) 2003 Elsevier B.V. All rights reserved.

The theoretical and experimental results show good agreement, suggesting that the simulation is a reasonable indicator of what may be expected in practice. Modeling of changes in detector-design parameters enabled quantification of the effects of varying neutron target material, neutron-converter foil thickness, drift gap width, and gas pressure on neutron spatial resolution, and the probability of a neutron-absorption event resulting in a count exceeding a lower level discriminator intended to filter out gamma-ray events. The results presented give guidance for selecting optimum Micromegas design parameters for neutron-detection applications. (C) 2003 Elsevier B.V. All rights reserved.

The elements of the polarized neutron beam, including a polarized He-3 neutron spin filter and a radio frequency neutron spin rotator, are described. Using CsI(Tl) detectors and photodiode current mode readout, measurements were made of asymmetries in gamma-ray emission following neutron capture on Cl-35, Cd-113, and La-139 targets. Upper limits on the parity-allowed asymmetry s(n) (.) (k(gamma) x k(n)) were set at the level of 7 x 10(-6) for all three targets. Parity-violating asymmetries S-n (.) k(gamma) were observed in Cl-35, A(gamma) = (-29.1 +/- 6.7) x 10(-6), and La-139, A(gamma) = (-15.5 +/- 7.1) x 10(-6), values consistent with previous measurements.

Monitoring stations separate xenon from air and perform isotopic analysis of the radioxenon. In one such radioxenon measurement scheme, the isotopes of interest are identified by coincident spectroscopy of electrons and photons in a beta/gamma coincidence spectrometer (BGCS). The beta spectrometer is a plastic scintillator, manufactured as a cylindrical cell containing the separated xenon sample. This cell is surrounded by the NaI(Tl) gamma spectrometer. We report here the development of a calibration process for the BGCS suitable for use in remote sampling systems. This procedure is based upon gamma-ray Compton scattering, resulting in a true coincident signal in both detectors, generation of electrons over a wide energy range that matches the energy distribution of electrons from radioxenon decay, and a relative insensitivity to source location. In addition to gain calibration, this procedure determines the resolution of the beta detector as a function of energy. (C) 2003 Elsevier B.V. All rights reserved.

Irreversible binding was consistently higher for DEP in brain, heart, kidneys and spleen but not lung where CLG >DEP and not in thyroid where there is no DEP binding. The generally higher DEP binding is consistent with its higher enzyme affinity and larger free fraction in plasma while differences in regional distribution for CLG and DEP in brain, heart, thyroid and lungs are consistent with different relative ratios of MAO A and B in humans.

A group of consecutive genes is considered as a candidate operon if both their gene sequences and functions are conserved across several phylogenetically related genomes. In addition, various supporting data for operons are also collected through the application of public domain computer programs, and used in our prediction method. These include the prediction of conserved gene functions, promoter motifs and terminators. An apparent advantage of our approach over other operon prediction methods is that it does not require many experimental data (such as gene expression data and pathway data) as input. This feature makes it applicable to many newly sequenced genomes that do not have extensive experimental information. In order to validate our prediction, we have tested the method on Escherichia coli K12, in which operon structures have been extensively studied, through a comparative analysis against Haemophilus influenzae Rd and Salmonella typhimurium LT2. Our method successfully predicted most of the 237 known operons. After this initial validation, we then applied the method to a newly sequenced and annotated microbial genome, Synechococcus sp. WH8102, through a comparative genome analysis with two other cyanobacterial genomes, Prochlorococcus marinus sp. MED4 and P.marinus sp. MIT9313. Our results are consistent with previously reported results and statistics on operons in the literature. C1 Univ Calif Riverside, Dept Comp Sci & Engn, Riverside, CA 92521 USA.

Chro likely exerts its activity by interfering with replication and transcription. Chro forms a dimer, mediated by a divalent metal ion, which binds to G/C-rich DNA. Herein we report the first crystal structure of Chro bound to d(TTG GCCAA)(2) DNA duplex solved by multiwavelength anomalous diffraction (MAD) based on the chelated Co3+ ion. The structure of the Mg2+ complex was subsequently refined at 2.15 Angstrom resolution, which revealed two complexes of metal-coordinated dimers of Chro bound to the octamer DNA duplex in the asymmetric unit. The metal ion is octahedrally coordinated to the O1 and O9 oxygen atoms of the chromophore (CPH), and two water molecules act as the fifth and sixth ligands. The two coordinated water molecules are hydrogen bonded to O2 atoms of C5 and C13 bases. The Chro dimer binds at and significantly widens the minor groove of the GGCC sequence. The long axis of each chromophore lies along and stacks over the sugar-phosphate backbone with the two attached saccharide moieties (rings A/B and C/D/E) wrapping across the minor groove. DNA is kinked by 30degrees and 36degrees in the two complexes, respectively. Six G-specific hydrogen bonds between Chro and DNA provide the GGCC sequence specificity. Interestingly, DNA in concert with Chro appears to act as an effective template to catalyze the deamination of Co(NH3)(6)(3+), as shown by circular dichroism and crystal structure data. Our results present useful structural information for designing new anticancer drug derivatives in the future. C1 Acad Sinica, Inst Biol Chem, Taipei 115, Taiwan.

The SCOR database contains multiple examples of a newly described RNA motif, the extruded helical single strand. Internal loop base triples are classified in SCOR according to their three-dimensional context. These internal loop triples contain several examples of a frequently found motif, the minor groove AGC triple. SCOR also presents the predominant and alternate conformations of hairpin loops, as shown in the most well represented tetraloops, with consensus sequences GNRA, UNCG and ANYA. The ubiquity of the GNRA hairpin turn motif is illustrated by its presence in complex internal loops. C1 Univ Calif Berkeley, Dept Plant & Microbial Biol, Berkeley, CA 94720 USA.

Hydrogen, on the other hand, is an important impurity in III-V semiconductors. Using first-principles band structure calculations we find that N can also qualitatively alter the electronic behavior of hydrogen in III-V semiconductors. We show that in GaAsN and GaPN a H atom bonds preferentially to the more electronegative N and can act as a donor in its own right. At high Fermi energy and H concentration, the H-2* complex associated with N is stabilized. The formation of the H-2* removes the effect of N on the band gap, restoring the gap of GaAs. For GaPN, the calculated local vibrational frequencies and isotope shifts of H-2* are in good agreement with experiments. (C) 2003 Elsevier B.V. All rights reserved.

However, jaguars have historically been difficult to monitor. This paper outlines the first application of a systematic camera trapping methodology for abundance estimation of jaguars. The methodology was initially developed to estimate tiger abundance in India. We used a grid of camera traps deployed for 2 months, identified individual animals from their pelage patterns, and estimated population abundance using capture-recapture statistical models. We applied this methodology in a total of five study sites in the Mayan rainforest of Belize, the Chaco dry forest of Bolivia, and the Amazonian rainforest of Bolivia. Densities were 2.4-8.8 adult individuals per 100 km(2), based on 7-11 observed animals, 16-37 combined 'captures' and 'recaptures', 486-2,280 trap nights, and sample areas of 107-458 km(2). The sampling technique will be used to continue long-term monitoring of jaguar populations at the same sites, to compare with further sites, and to develop population models. This method is currently the only systematic population survey technique for jaguars, and has the potential to be applied to other species with individually recognizable markings.

The thermal conductivity of as-sprayed YAG/YSZ coatings was reduced due to excessive porosity and amorphous areas in the YAG layer. After long-term heat treatments, the conductivity of the multilayer was unaffected by the presence of YAG. Sintering and recrystallization of the amorphous YAG regions occurred during high-temperature heat treatments. While YAG itself possesses excellent phase stability, its presence also improved the phase stability of zirconia near the YAG/YSZ interface, inhibiting the outward diffusion of yttrium from high-yttria t-ZrO2 The YAG layer reduced the NiCoCrAlY bond-coat oxidation rate by a factor of three during isothermalfurnace tests conducted at 1200degreesC.

By adding Y as an oxide dispersion (OD), problems with NiYx formation and internal oxidation were avoided. Short-term isothermal and cyclic-oxidation performance at 1200degrees - 1500degreesC was compared to cast NiAl alloys with and without Zr. Results indicate that the Y2O3 addition was beneficial to scale adhesion and significantly modified the alpha- Al2O3 scale microstructure, similar to a Zr alloy addition. However, at 1400 and 1500degreesC, neither the Y2O3 or Zr additions changed the scale- growth rate, eliminated the formation of voids at the metal-scale interface or prevented scale spallation. These similarities in performance suggest that similar mechanisms occur when the reactive element is added as either an OD or an alloy addition. C1 MIT, HH Uhlig Corros Lab, Cambridge, MA 02139 USA.

It is shown that EELS in a transmission electron microscope may be used to circumvent the difficulty of producing single-phase or single-crystal samples owing to its high spatial resolution, and that diffraction patterns and images can be acquired, providing unambiguous phase determination when acquiring spectra. EELS results are supported by synchrotron-radiation-based X-ray absorption, multielectron atomic spectral simulations, and local density approximation calculations based on density-functional theory with the generalized gradient approximation. For Ce, it is shown that changes in {111} stacking sequences can drive substantial modi. cations in the electronic structure of close-packed phases of Ce that have similar atomic volumes, contrary to previous assumptions in literature. For Pu, it is shown that Russell - Saunders (L - S) coupling fails for the 5f states and that either a j - j or an intermediate scheme must be used for the actinides because of the considerable spin - orbit interaction in the 5f states. We present a model showing how the 5f states behave along the light actinide series. C1 Lawrence Livermore Natl Lab, Chem & Mat Sci Directorate, Livermore, CA 94550 USA.

Interactions of these defects between themselves and with existing microstructure features cause microstructure evolution and lead to changes in mechanical and physical properties of the irradiated materials. Models for prediction of radiation-induced changes should include details of reactions involving defects, and so in this paper we present the results of atomic-scale computer modelling of interactions between a cluster of self-interstitial atoms (SIAs) and a single vacancy in models of bcc, fcc and hcp metals. The vacancy is taken to lie on or within the glide prism of the cluster. This type of reaction is considered to be one of the most frequent because formation of SIA clusters, particularly glissile clusters, is commonly observed in high-energy displacement cascades in all metals. The interaction depends strongly on the dislocation nature of the cluster and therefore these interactions are different in the three crystal structures. Vacancy - SIA recombination, in particular, is inhibited by dissociation of the SIA loop on its glide prism.

Yet, if we concentrate our attention on the specific episodes marked by a crash followed by a rebound, then we observe that stock prices have a strong connection with interest rates on one hand, and with bond yield spreads on the other hand. That second relationship is particularly stable in the course of time having been observed for over 140 years. Throughout the paper we use a quasi-experimental approach. By observing how markets respond to well-defined exogenous shocks (such as the shock of 11 September 2001) we are able to determine how investors organize their "flight to safety": which safe haven they select, how long their collective panic lasts, and so on. As rebounds come to an end the correlation of stock and bond prices fades away, a clear sign that the collective behavior of investors loses some of its coherence; this observation can be used as an objective criterion for assessing the end of a market rebound. Based on the behavior of investors, we introduce a distinction between "genuine stock market rallies", as opposed to spurious rallies such as those brought about by the buyback programs implemented by large companies. The paper ends with a discussion of testable predictions. (C) 2003 Elsevier B.V. All rights reserved. C1 Brookhaven Natl Lab, Dept Phys, Upton, NY 11973 USA.

The X-ray diffraction of the sample annealed at elevated temperatures indicates that intergrowths may exist in the compound at equilibrium when 0.6 < y < 1.4. Its low-temperature equilibrium diamagnetization M-s varies linearly with y, but is insensitive to the intergrowth, indicative of quasi-2D superconductivity. The T-c-onset, especially, shifts only slightly with y. Our data from cold compressed samples, on the other hand, show that the water loss non-proportionally suppresses the diamagnetization, which is suggestive of weak links. (C) 2003 Elsevier B.V.

These materials are important as substrates for "RABiTS"-type coated conductors that incorporate high temperature superconductors for current transport. The quasi-static dc and ac hysteretic loss W was determined to support estimates of the ferromagnetic contribution to the overall ac loss in potential ac applications. The alloys were prepared by either vacuum casting or powder metallurgy methods, and the hysteretic loss tended to be lower in materials that were recrystallized at higher temperatures. Some samples were progressively deformed (0.4% bending strain) to simulate winding operations; this increased the hysteretic loss, as did sample cutting operations that create localized damage. In ac magnetization measurements, the effects of ac frequency and dc bias field on the ferromagnetic loss were determined. (C) 2003 Elsevier B.V. All rights reserved.

Scanning electron microscopy of the ISD MgO films showed columnar grain structures with a roof-tile-shaped surface.

A full width at half maximum (FWHM) of approximate to10degrees was observed in the phi-scan for MgO films. Yttria-stabilized zirconia (YSZ) and ceria (CeO2) buffer layers were epitaxially grown on ISD MgO by pulsed laser deposition (PLD) prior to YBCO deposition by PLD. The YBCO films grown on YSZ/CeO2 buffered ISD MgO substrates were biaxially aligned with the YBCO c-axis normal to the substrate surface.

In this paper we discuss efforts to achieve an understanding of the two different types of transport measurements (which we refer to as drag and tunneling experiments, respectively) that have been carried out in bilayer quantum Hall systems by the group of Jim Eisenstein at the California Institute of Technology. In a drag experiment, current is sent through one of the two-layers and the voltage drop is measured in the other layer. We will argue that the finding of these experiments that the voltage drop in the drag layer is different from that in the drive layer, is an experimental proof that these bilayers do not have quasi-long-range excitonic order. The property that at nu=1 the longitudinal drag voltage increases from near zero when spontaneous coherence is initially established, then falls back toward zero as it becomes well established, can be explained as a competition between the broken symmetry and the gap to which it gives rise. In the tunneling experiment, current is injected in one layer and removed from the other layer. The absence of quasi-long-range order likely explains the relatively small tunneling conductance per area found in the these measurements. (C) 2003 Published by Elsevier B.V.

A new sigma(-)-polarized emission peak emerged on the higher energy side of a main peak in the sigma(-) polarization around the Landau filling factor v of 1. Magnetic field dependence of the main peak energy exhibited a novel two-step like behavior around v of 0.9 and that of the peak intensity was observed to take local maximum there. With increasing the field angle, these features of the main peak disappeared. Temperature dependence of the profiles of these emission peaks was also investigated to 40 T between 1.3 and 20 K. Relative intensity of the new emission peak to the main one was found to decrease with increasing temperature. Taking into consideration that a larger Zeeman gap should be unfavorable to a spin-singlet charged exciton (X-) and degradation of quantum limit by thermal excitation could be unfavorable to a spin-triplet X-, the new peak is assigned to the spin-triplet X- and the main peak to the spin-singlet X-.

Measurements were not constrained to one energy but were carried out over a 5 keV-20 keV energy range. These measurements used powder diffraction to determine the synchrotron beam energy, to diagnose discrepancies in the nominal calibrated beam energies, and to determine beam energy bandwidths as a function of energy. More specifically, this technique is able to yield a result independent of certain energy-dependent systematics and to yield the most accurate determination of the lattice spacing of NIST SRM 660 LaB6 standard powder so far undertaken. This has direct application to beam line energy calibration, structural evaluation, edge energy calibration, and lattice spacing determinations.

We show that corrections to this approach can be minimized by taking the separation radius inside the interval determined by simple expressions. The resulting modified two-potential approach reproduces the resonance's energy and the width, both for narrow and wide resonances. We also demonstrate that, without losing its accuracy, the two-potential approach can be modified to a form resembling the R-matrix theory, yet without any uncertainties related to the choice of the matching radius.

Our numerical results show that populations of Rydberg atoms can be driven down to lower n levels with a train of half-cycle pulses. Oscillations of the Rydberg population through both n levels and l levels are observed during these interactions. The approach may have applications in providing an effective mechanism for producing near ground-state atoms from the initially high-Rydberg distributions found in recombining ultracold plasmas such as encountered in the antihydrogen trapping experiments at CERN.

Several states have polarizabilities more than two orders of magnitude larger than might be expected from the known energy levels of Ba, implying the existence of two previously unobserved odd-parity states nearby. These two states are located using Stark-induced excitation, and tentatively identified as (Xe)6s8p P-3(0,2).

The observed differences in the ionization characteristics provide a measure of the anisotropy of the momentum distribution. It is shown that HCP's applied transverse to the atomic axis provide a particularly sensitive probe of the quasi-1D nature of the state. The experimental data are in good agreement with the results of classical trajectory Monte Carlo simulations. C1 Rice Univ, Dept Phys & Astron, Houston, TX 77005 USA.

The low-temperature end of the measurements was 0.5 K for TaV2H0.18 and 3 K for TaV2D0.17 and TaV2D0.50. In many C15 compounds, including TaV2, hydrogen isotopes occupy the interstitial g sites, which form a network of linked hexagons. For all three materials, a relatively large attenuation peak was observed near room temperature for measurement frequencies in the range of 1 MHz. This peak was associated with H (D) hopping between hexagons, the rate-limiting step for long-range diffusion. Much smaller attenuation peaks were observed for both H and D in each material at low temperatures and attributed to local motion within a hexagon of g sites. These small, low-temperature loss peaks showed totally nonclassical behavior with the H (D) motion exhibiting a very large isotope effect: the relaxation rate for H was over an order of magnitude faster than that for D for similar concentrations. The relaxation rates for the local motion were satisfactorily described by a nonclassical expression with parameters for TaV2D0.50 in agreement with previous NMR measurements for this deuterium concentration. In qualitative agreement with neutron scattering results, it was necessary to assume a temperature-dependent mobile population of H (D) in order to explain the low-temperature attenuation peaks. As further evidence of the nonclassical nature of the motion, the mobile H population was not frozen out on the time scale of the ultrasonic measurements (approximate to1 MHz) down to 1 K. Previously undetected attenuation peaks were observed at an intermediate-temperature range and attributed to an order-disorder transition of the H (D) atoms. It seems likely that this transition is related to the temperature dependence of the mobile population. C1 Colorado State Univ, Dept Phys, Ft Collins, CO 80523 USA.

In particular, motivated by recent experiments on vanadium-doped chromium, we study the variation of transport coefficients with the onset of magnetism within a mean-field treatment of a model that contains nearly nested electron and hole Fermi surfaces. We show that most transport coefficients display a leading dependence that is linear in the energy gap. The coefficient of the linear term, though, can be small. In particular, we find that the Hall conductivity sigma(xy) is essentially unchanged, due to electron-hole compensation, as the system goes through the quantum critical point. This conclusion extends a similar observation we made earlier for the case of completely flat Fermi surfaces to the immediate vicinity of the quantum critical point where nesting is present but not perfect.

The deviations from the idealized Gaussian behavior expected for an isotropic-harmonic vibrator within the amorphous phase and disordered crystal are found to be remarkably close. Such proximity enables us to take advantage of the crystal symmetry to gain access to specific details of the effective interparticle potential. Once this is done the treatment is extended to include the fully amorphous material. The results depict atomic motions within the glassy matrices as significantly anisotropic and highly anharmonic and thus provide a way to understand the microscopic origin of phenomena considered as fingerprints of glassy dynamics.

The electronic resonance associated with the stretching mode of atop CO appeared at 2.51 eV with a bandwidth of 0.83 eV. The result is consistent with earlier calculations using CO-Pt cluster models indicating that the resonance is from 5d to 6sp orbital of Pt hybridized with orbital of CO. The measured transition energy suggests that the antibonding state of Pt 6sp and CO 5sigma for atop CO on Pt(111) is similar to2.2 eV above Fermi level.

The melting temperatures of these clusters were estimated to be 1300 K, 2100 K, 2000 K, and 1900 K, respectively, which are all above the melting temperature (505 K) of bulk tin. These results are consistent with recent ion mobility measurements. C1 Iowa State Univ, US Dept Energy, Ames Lab, Ames, IA 50011 USA. Iowa State Univ, Dept Phys & Astron, Ames, IA 50011 USA.

Combining Lanczos diagonalization with Chebyshev moment expansion we calculate exactly the photoemission and inverse photoemission spectra, and use these to establish the phase diagram of the model. While polaronic features emerge only at strong electron-phonon couplings, pronounced phonon signatures, such as multiquanta band states, can be found in the Mott insulating regime as well. In order to corroborate the Mott to Peierls transition scenario, we determine the spin- and charge-excitation gaps by a finite-size scaling analysis based on density-matrix renormalization-group calculations.

The surface region is a relaxed truncated bulk structure, having the same composition as the bulk. The outermost layer spacing is contracted by 10% relative to the bulk interlayer spacing, while the next layer spacing is expanded by 5%. A small degree of intralayer rumpling was observed within each layer. There is a one-to-one correspondence between protrusions observed in the STM images and a subset of atoms in the model structure, indicating that in-plane reconstruction is minimal.

Strong (over three orders of magnitude) dipolar resonant enhancements of the magnetic reflections were observed at both Gd L-II and L-III edges, indicating a relatively high magnetic polarization of the Gd 5d levels. Three-dimensional magnetic fluctuations are evidenced below T-N, while measurements taken slightly above T-N are consistent with two coexisting length scales for the magnetic correlations.

We discuss the spectra measured above and below the semiconductor-insulator transition temperature with the aid of a detailed formal analysis of the energy and polarization dependences of the structure factors and ab initio calculations of the spectra. In the low-temperature insulating phase, we find that inequivalent Mn atoms order in a CE-type pattern and that the crystallographic structure of La0.5Ca0.5MnO3 [Radaelli , Phys. Rev. B 55, 3015 (1997)] can also describe this system in detail. Instead, the alternative structure proposed for the so-called Zener-polaron model [Daoud-Aladine , Phys. Rev. Lett. 89, 097205 (2002)] is ruled out by crystallographic and spectroscopic evidence. Our analysis supports a model involving orbital ordering. However, we confirm that there is no direct evidence of charge disproportionation in the Mn K-edge resonant spectra. Therefore, we consider a CE-type model in which there are two Mn sublattices, each with partial e(g) occupancy. One sublattice consists of Mn atoms with the 3x(2)-r(2) or 3y(2)-r(2) orbitals partially occupied in an alternating pattern, the other sublattice with the x(2)-y(2) orbital partially occupied.

Short-range correlations are treated exactly using a dynamical cluster approximation quantum Monte Carlo (QMC) simulation, while longer-length-scale physics requiring larger cluster sizes is incorporated through the introduction of the fluctuation-exchange approximation. The properties of the resulting hybrid scheme are examined and the description of local-moment formation is compared to exact results in one dimension (1D). The effects of electron-electron coupling and electron doping on the shape of the Fermi surface are demonstrated in 2D. Causality is examined in both 1D and 2D. We find that the scheme is successful if QMC clusters of N(C)greater than or equal to4 are used (with sufficiently high temperatures in 1D), however, very small QMC clusters of N-C=1 lead to acausal results.

The data show that two types of screening currents occur within the high-magnetic-field, low-temperature charge-density wave (CDWx) phases of these salts in response to time-dependent magnetic fields. The first, which gives rise to the induced Hall potential, is a free current (j(free)), present at the surface of the sample. The time constant for the decay of these currents is much longer than that expected from the sample resistivity. The second component of the current appears to be magnetic (j(mag)), in that it is a microscopic, quasiorbital effect; it is evenly distributed within the bulk of the sample upon saturation. To explain these data, we propose a simple model invoking a new type of quantum fluid comprising a CDW coexisting with a two-dimensional Fermi-surface pocket which describes the two types of current. The model and data are able to account for the body of previous experimental data which had generated apparently contradictory interpretations in terms of the quantum Hall effect or superconductivity.

Three excitations, which show little dependence on momentum transfer, are observed in our measurements. The lowest-energy excitation at similar to2.1 eV is dispersionless and is attributed to a localized d-d orbital excitation. We also observe two excitations at similar to5.4 eV and similar to7.6 eV which we assign to charge-transfer excitations. These high-energy excitations are also dispersionless along the copper-oxygen chain direction. However, in each case we observe a small energy dispersion along the direction perpendicular to the copper-oxygen ribbons, suggesting a significant interchain coupling in this system. We also discuss the possible implications of ferromagnetic nearest-neighbor intrachain coupling on the charge excitation spectra. C1 Brookhaven Natl Lab, Dept Phys, Upton, NY 11973 USA.

Using intense magnetic pressure produced by the Sandia National Laboratories Z accelerator, macroscopic aluminum or titanium flyer plates, several mm in lateral dimensions and a few hundred microns in thickness, have been launched to velocities in excess of 22 km/s, producing constant pressure drive times of approximately 30 ns in plate impact, shock wave experiments. This flyer plate technique was used to perform shock wave experiments on LD(2) to examine its high-pressure equation of state. Using an impedance matching method, Hugoniot measurements of LD(2) were obtained in the pressure range of similar to22-100 GPa. Results of these experiments indicate a peak compression ratio of approximately 4.3 on the Hugoniot. In contrast, previously reported Hugoniot states inferred from laser-driven experiments indicate a peak compression ratio of approximately 5.5-6 in this same pressure range. The stiff Hugoniot response observed in the present impedance matching experiments was confirmed in simultaneous, independent measurements of the relative transit times of shock waves reverberating within the sample cell, between the front aluminum drive plate and the rear sapphire window. The relative timing was found to be sensitive to the density compression along the principal Hugoniot. Finally, mechanical reshock measurements of LD(2) using sapphire, aluminum, and alpha-quartz anvils were made. These results also indicate a stiff response, in agreement with the Hugoniot and reverberating wave measurements. Using simple model-independent arguments based on wave propagation, the principal Hugoniot, reverberating wave, and sapphire anvil reshock measurements are shown to be internally self-consistent, making a strong case for a Hugoniot response with a maximum compression ratio of similar to4.3-4.5. The trends observed in the present data are in very good agreement with several ab initio models and a recent chemical picture model for LD(2), but in disagreement with previously reported laser-driven shock results. Due to this disagreement, significant emphasis is placed on the discussion of uncertainties, and the potential systematic errors associated with each measurement.

At low temperatures, a positive spin-1/2 resonance is observed, i.e., the changes in J, the EL intensity I-EL, and the PL intensity I-PL are positive (DeltaJ/J, DeltaI(EL)/I-EL, and DeltaI(PL)/I-PL>0). DeltaJ/J and DeltaI(EL)/I-EL are insensitive to the nature of the Alq(3)/cathode interface. They weaken with increasing T and become unobservable above 60 K. DeltaI(PL)/I-PL also decreases with T, but is still observable at 250 K. Since the resonances all have the same g value, similar linewidths, and a similar dependence on T and the excitation level (J or the laser power), they are all attributed to the same mechanism. That mechanism is either the reduction of singlet exciton (SE) quenching by a reduced population of polarons in the bulk of the Alq(3) layer ("the quenching mechanism"), or the enhanced formation of SEs from singlet polaron pairs at the expense of triplet excitons (TEs) ("the delayed PL mechanism"). However, the latter mechanism implies that the yield of SEs in Alq(3)-based OLEDs is greater than 25%. Due to evidence to the contrary, and other evidence which is inconsistent with the delayed PL mechanism, we conclude that the positive spin-1/2 resonance is due to the quenching mechanism. At Tapproximate to60 K, another spin-1/2 resonance, which reduces both J and I-EL (but is unobservable in the PL), emerges and grows with increasing T. This negative EDMR and ELDMR is sensitive to the buffer layer between Alq(3) and the cathode, and is attributed to the magnetic resonance enhancement of the spin-dependent formation of negative spinless bipolarons from spin-1/2 negative polarons at the organic/cathode interface. The increased trapping of injected electrons at the interface reduces J and consequently I-EL. However, at 295 K, the ratio \DeltaI(EL)/I-EL\ in Alq(3)/AlOx/Al devices to that in Alq(3)/CsF/Al devices is significantly lower than the ratio of \DeltaJ/J\ in these devices. Hence we suspect that other mechanisms, unidentified at this point, are also contributing to the negative ELDMR. C1 Iowa State Univ, US DOE, Ames Lab, Ames, IA 50011 USA.

The high-temperature phase adopts the orthorhombic Gd5Si4-type structure, and the low-temperature phase has the monoclinic Gd5Si2Ge2-type structure. Unlike the magnetic/martensitic transition in Gd5Si2Ge2, the structural change in Er5Si4 is not coupled with a magnetic transition, and the structural sequence below room temperature is just the reverse. A vibrational mode that breaks half of the interslab silicon dimers and rotates slabs in the monoclinic structure, thus lowering the symmetry from Pnma to P112(1)/a, has been identified using Landau theory. While the monoclinic phase is electronically stabilized at low temperatures, the orthorhombic phase is entropically preferable at high temperatures.

The x-ray spectra are in good agreement with an sp(3)s(*) tight-binding model in which nitrogen is included in a supercell configuration and the disorder in the nitrogen distribution is neglected. A strong peak in the x-ray absorption spectrum is interpreted as a nitrogen resonant state in the conduction band rather than as an electron-hole exciton. The tight-binding calculation is also in good agreement with the observed nitrogen concentration dependence of the optical band gap.

The nanocrystalline material exhibited an enhancement in its DOS at low energies by a factor of 2.2. This enhancement persisted throughout the entire pressure range, although it was reduced to about 1.7 after decompression. The low-energy regions of the spectra were fitted to the function AE(n), giving values of n close to 2 for both the bulk control sample and the nanocrystalline material, indicative of nearly three-dimensional vibrational dynamics. At higher energies, the van Hove singularities observed in both samples were coincident in energy and remained so at all pressures, indicating that the forces conjugate to the normal coordinates of the nanocrystalline materials are similar to the interatomic potentials of bulk crystals.

The crystal field (CF) of Er3+ splits the 16-fold degenerate I-4(15/2) ground-state multiplet of 4f(11) electrons into eight Kramers doublets 4Gamma(6)+4Gamma(7) within the D-4h site symmetry. Therefore, one expects seven ground-state CF transitions from the lowest Gamma(6) state to the higher states. Excitation symmetries and transition characteristics between these levels can be identified systematically by a proper use of the Raman polarization selection rules. As a result, temperature-dependent and polarized Raman-scattering spectra reveal six ground-state CF transitions: 7 cm(-1) (Gamma(6)-->Gamma(7)), 48 cm(-1) (Gamma(6)-->Gamma(6)), 56 cm(-1) (Gamma(6)-->Gamma(7)), 145 cm(-1) (Gamma(6)-->Gamma(7)), 149 cm(-1) (Gamma(6)-->Gamma(6)), and 153 cm(-1) (Gamma(6)-->Gamma(7)). Using the CF transition characteristics of the obtained data, we expect that one unobserved CF level transition (Gamma(6)-->Gamma(6)) lies between 56 cm(-1) and 145 cm(-1).

They are found to systematically differ from the rigid-body values. The difference is attributed to shell effects which are well described by a rotating Woods-Saxon potential. The data and quantal calculations are interpreted by means of the semiclassical periodic orbit theory. From this new perspective, features in the moments of inertia as a function of neutron number and spin as well as their relation to the shell energies can be understood. Gross shell effects persist up to the highest angular momenta observed. C1 Univ Calif Berkeley, Lawrence Berkeley Lab, Div Nucl Sci, Berkeley, CA 94720 USA.

Chiral perturbation theory is used to classify and identify the leading-order terms. Specific forms of the related one- and two-body tree-level diagrams are derived. As a first step toward a full calculation, a few tree-level two-body diagrams are evaluated at each considered order, using a simplified set of d and alpha wave functions and a plane-wave approximation for the initial dd state. The leading-order pion-exchange term is shown to be suppressed in this model because of poor overlap of the initial and final states. The higher-order one-body and short-range (heavy-meson-exchange) amplitudes provide better matching between the initial and final states and therefore contribute significantly and coherently to the cross section. The consequences this might have for a full calculation, with realistic wave functions and a more complete set of amplitudes, are discussed. C1 Indiana Univ, Dept Phys, Bloomington, IN 47405 USA.

In addition, we find that the transition region between the fragmentation and the central plateau regions exhibits a second kind of universal behavior that is only apparent in d(2)n/deta(2). The roots dependence of the height of the central plateau (dn/deta)(eta=0) and the total charged particle multiplicity n(total) critically depend on the behavior of this universal transition curve. Analyzing available Relativistic Heavy-Ion Collider (RHIC) data, we show that (dn/deta)(eta=0) can be bounded by ln(2)s and n(total) can be bounded by ln(3)s. We also show that the deuteron-gold data from RHIC has exactly the same features as the gold-gold data indicating that these universal behaviors are a feature of the initial state parton-nucleus interactions and not a consequence of final state interactions.

sections and recoil polarizations for the reactions gamma+p-->K++Lambda and gamma+p-->K++Sigma(0) have been measured at CLAS for center-of-mass energies between 1.6 and 2.3 GeV. In the K(+)Lambda channel we confirm a resonance-like structure near W=1.9 GeV at backward kaon angles. Our data show more complex s- and u- channel behavior than previously seen, since structure is also present at forward angles, but not at central angles. The position and width change with angle, indicating that more than one resonance is playing a role. Large positive Lambda polarization at backward angles, which is also energy dependent, is consistent with sizable s- or u-channel contributions. Presently available model calculations cannot explain these aspects of the data. C1 Carnegie Mellon Univ, Pittsburgh, PA 15213 USA. Arizona State Univ, Tempe, AZ 85287 USA.

The reaction dynamics are displayed in total cross sections, Dalitz plots, invariant-mass spectra, production angular distributions, and the Lambda polarization. The pi(0)pi(0)Lambda production is dominated by the pi(0)Sigma(0)(1385) intermediate state; no trace of other light Sigma* states is observed, and the role of the f(0)(600) meson appears to be insignificant. A striking similarity is seen between K(-)p-->pi(0)pi(0)Lambda and pi(-)p-->pi(0)pi(0)n; this can be understood as a consequence of dynamical flavor symmetry.

The data were obtained using the Crystal Ball multiphoton spectrometer, which has 93% of 4pi solid angle coverage. The dynamics of the pi(-)p-->pi(0)pi(0)n reaction and the dependence on the beam energy are displayed in total cross sections, Dalitz plots, invariant-mass spectra, and production angular distributions. Special attention is paid to the evaluation of the acceptance that is needed for the precision determination of the total cross section sigma(t)(pi(-)p-->pi(0)pi(0)n). The energy dependence of sigma(t)(pi(-)p-->pi(0)pi(0)n) shows a shoulder at the Roper resonance [i.e., the N(1440)1/2(+)], and there is also a maximum near the N(1520)3/2(-). It illustrates the importance of these two resonances to the pi(0)pi(0) production process. The Dalitz plots are highly nonuniform; they indicate that the pi(0)pi(0)n final state is dominantly produced via the pi(0)Delta(0)(1232) intermediate state. The invariant-mass spectra differ much from the phase-space distributions. The production angular distributions are also different from the isotropic distribution, and their structure depends on the beam energy. For beam momenta above 550 MeV/c, the density distribution in the Dalitz plots strongly depends on the angle of the outgoing dipion system (or equivalently on the neutron angle). The role of the f(0)(600) meson (also known as the sigma) in pi(0)pi(0)n production remains controversial. C1 Univ Calif Los Angeles, Los Angeles, CA 90095 USA.

These ratios have a large impact on the astrophysical reaction rates of O-15(alpha,gamma)Ne-19, F-18(p,gamma)Ne-19, and F-18(p,alpha)O-15, which are of interest in understanding energy generation in x-ray bursts and in interpreting anticipated gamma-ray observations of novae. We detected decay protons and alpha particles using a silicon detector array in coincidence with tritons measured in the focal plane detector of our Enge split-pole spectrograph. The silicon array consists of five strip detectors of the type used in the Louvain-Edinburgh Detector Array, subtending angles from 130degrees to 165degrees with approximate to14% lab efficiency. The correlation angular distributions give additional confidence in some prior spin-parity assignments that were based on gamma branchings. We measure Gamma(p)/Gamma=0.387+/-0.016 for the 665 keV proton resonance, which agrees well with the direct measurement of Bardayan C1 Yale Univ, AW Wright Nucl Struct Lab, New Haven, CT 06520 USA.

In addition to flavor-inclusive Z(0) decays, measurements are made for Z(0) decays into light (u, d, s), c, and b primary flavors, selected using the upgraded vertex detector. Large differences between the flavors are observed that are qualitatively consistent with expectations based upon previously measured production and decay properties of heavy hadrons. These results are used to test the predictions of QCD in the modified leading logarithm approximation, with the ansatz of local parton-hadron duality, and the predictions of three models of the hadronization process. The light-flavor results provide improved tests of these predictions; the heavy-flavor results provide complementary model tests. In addition we have compared hadron and antihadron production in light quark (as opposed to antiquark) jets. Differences are observed at high momentum for all three charged hadron species, providing direct probes of leading particle effects, and stringent constraints on models.

S=1.8 TEV; QUARK PRODUCTION; CROSS-SECTION; BOTTOM-QUARK; COLLISIONS; J/PSI; COLLIDER; FERMILAB; DETECTOR; DECAYS AB We present a detailed examination of the heavy flavor properties of jets produced at the Fermilab Tevatron collider. The data set, collected with the Collider Detector at Fermilab, consists of events with two or more jets with transverse energy E(T)greater than or equal to15 GeV and pseudorapidity \eta\less than or equal to1.5. The heavy flavor content of the data set is enriched by requiring that at least one of the jets (lepton-jet) contains a lepton with a transverse momentum larger than 8 GeV/c. Jets containing hadrons with heavy flavor are selected via the identification of secondary vertices. The parton-level cross sections predicted by the HERWIG Monte Carlo generator program are tuned within theoretical and experimental uncertainties to reproduce the secondary-vertex rates in the data. The tuned simulation provides new information on the origin of the discrepancy between the b (b) over bar cross section measurements at the Tevatron and the next-to-leading order QCD prediction. We also compare the rate of away-jets (jets recoiling against the lepton-jet) containing a soft lepton (p(T)greater than or equal to2 GeV/c) in the data to that in the tuned simulation. We find that this rate is larger than what is expected for the conventional production and semileptonic decay of pairs of hadrons with heavy flavor. C1 Univ Florida, Gainesville, FL 32611 USA.

In particular a resonant enhancement of leptogenesis via heavy quasi-Dirac right-handed neutrino pairs can occur without a special flavor form or "texture" of the mass matrices being assumed. Some of the requirements for neutrino mixing and leptogenesis are effectively decoupled. C1 No Illinois Univ, Dept Phys, De Kalb, IL 60115 USA. Fermilab Natl Accelerator Lab, Batavia, IL 60510 USA.

Our approach uses sector decomposition of the exclusive final-state phase space to enable extraction of all singularities of the real emission matrix elements before integration over any kinematic variable. The exact kinematics of the real emission process are preserved in all regions of phase space. Traditional approaches to extracting singularities from real emission matrix elements, such as phase space slicing and dipole subtraction, require both the determination of counterterms for double real emission amplitudes in singular kinematic limits and the integration of these contributions analytically to cancel the resulting singularities against virtual corrections. Our method addresses both of these issues. The implementation of constraints on the final-state phase space, including various jet algorithms, is simple using our approach. We illustrate our method using e(+)e(-)--> jets at O(alpha(S)(2)) as an example. C1 Stanford Univ, Stanford Linear Accelerator Ctr, Stanford, CA 94309 USA.

We demonstrate that the residual chiral symmetry breaking, which is present for a finite number of lattice sites in the fifth dimension (L-s), can be substantially suppressed using improved gauge actions. In particular the Symanzik action, the Iwasaki action, and a renormalization group improved gauge action, called the doubly blocked Wilson (DBW2) action, are studied and compared to the Wilson action. All improved gauge actions studied show a reduction in the additive residual quark mass m(res). Remarkably, in the DBW2 case m(res) is roughly two orders of magnitude smaller than the Wilson gauge action at a(-1)=2 GeV and L-s=16. Significant reduction in m(res) is also realized at stronger gauge coupling corresponding to a(-1)=1.3 GeV. As our numerical investigation indicates, this reduction is achieved by reducing the number of topological lattice dislocations present in the gauge field configurations. We also present detailed results for the quenched light hadron spectrum and the pion decay constant using the DBW2 gauge action. C1 Brookhaven Natl Lab, RIKEN BNL Res Ctr, Upton, NY 11973 USA.

K-c0(+/-) SO PHYSICAL REVIEW D LA English DT Article ID CHARMONIUM; DECAYS; STATE AB We present a measurement of the branching fraction of the decay B+/--->chi(c0)K(+/-) from a sample of 89x10(6) B (B) over bar pairs collected by the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. The chi(c0) meson is reconstructed through its two-body decays to pi(+)pi(-) and K+K-. We measure B(B+/- --> chi(c0)K(+/-)) x B(chi(c0) --> pi(+)pi(-)) = [1.32(-0.27)(+0.28)(stat) +/- 0.26(syst)] x 10(-6) and B(B+/- --> chi(c0)K(+/-)) x B(chi(c0) --> K+K-) = [1.49(-0.34)(+0.36)(stat) +/- 0.22(syst)] x 10(-6). Using the known values for the chi(c0) decays branching fractions, we combine these results to obtain B(B+/--->chi(c0)K(+/-))=(2.7+/-0.7)x10(-4).

the B+/B-0 production ratio from the Upsilon(4S) meson using B+-> J/psi K+ and B-0 -> J/psi K-S(0) decays SO PHYSICAL REVIEW D LA English DT Article ID B-MESONS AB We report a measurement of the production ratio of charged and neutral B mesons from Y(4S) decays based on the ratio of efficiency-corrected yields for the charmonium modes J/psiK(+) and J/psiK(s)(0) with 81.9 fb(-1) of data collected with the BABAR detector on the Y(4S) resonance at 10.580 GeV. We find a value of 1.006+/-0.036(stat)+/-0.031(syst) for the ratio R+/0=Gamma(Y(4S)-->B+B-)/Gamma(Y(4S)-->B-0(B) over bar (0)).

In this model gluons and quark momenta live in 1+1 dimensions only, but the quark spin and all other particles (leptons and the photon) live in the full 1+3 dimensions. The bound states of quarks and antiquarks are identical to those originally described by 't Hooft (except that there are new transversely polarized states previously excluded), so the model is exactly soluable. However, significant differences arise when the model is applied to electromagnetic interactions. After reviewing the strongly interacting sector of the theory, we discuss deep inelastic scattering (DIS) in this model, and show that the new states with transverse polarization give the Callan-Gross relation and remove the pathological features of the original (1+1)-dimensional description. We conclude that RQCD gives a satisfactory description of the phenomenology and provides a deep understanding of both duality and DIS.

We demonstrate that the small induced effects of chiral symmetry breaking inherent in this formulation can be described by a residual mass (m(res)) whose size decreases as the separation between the domain walls (L-s) is increased. However, at stronger couplings much larger values of L-s are required to achieve a given physical value of m(res). For beta=6.0 and L-s=16, we find m(res)/m(s)=0.033(3), while for beta=5.7, and L-s=48, m(res)/m(s)=0.074(5), where m(s) is the strange quark mass. These values are significantly smaller than those obtained from a more naive determination in our earlier studies. Important effects of topological near zero modes which should afflict an accurate quenched calculation are easily visible in both the chiral condensate and the pion propagator. These effects can be controlled by working at an appropriately large volume. A non-linear behavior of m(pi)(2) in the limit of small quark mass suggests the presence of additional infrared subtlety in the quenched approximation. Good scaling is seen both in masses and in f(pi) over our entire range, with inverse lattice spacing varying between 1 and 2 GeV. C1 Brookhaven Natl Lab, RIKEN BNL Res Ctr, Upton, NY 11973 USA.

The normal to the light front is specified by a general null vector omega(mu). The LFWFs with definite total angular momentum are eigenstates of a kinematic angular momentum operator and satisfy all Lorentz symmetries. They are analytic functions of the invariant mass squared of the constituents M-0(2)=(Sigmak(mu))(2) and the light-cone momentum fractions x(i)=k(i).omega/p.omega multiplied by invariants constructed from the spin matrices, polarization vectors, and omega(mu). These properties are illustrated using known nonperturbative eigensolutions of the Wick-Cutkosky model. We analyze the LFWFs introduced by Chung and Coester to describe static and low momentum properties of the nucleons. They correspond to the spin locking of a quark with the spin of its parent nucleon, together with a positive-energy projection constraint. These extra constraints lead to an anomalous dependence of form factors on Q rather than Q(2). In contrast, the dependence of LFWFs on M-0(2) implies that hadron form factors are analytic functions of Q(2) in agreement with dispersion theory and perturbative QCD. We show that a model incorporating the leading-twist perturbative QCD prediction is consistent with recent data for the ratio of proton Pauli and Dirac form factors.

Results are given for both the standard model and the minimal supersymmetric standard model. The exclusive b (b) over barh production rate is small in the standard model, but it can be greatly enhanced in the minimal supersymmetric standard model for large tan beta, making b (b) over barh an important discovery mode. We find that the next-to-leading order QCD results are much less sensitive to the renormalization and factorization scales than the lowest order results, but have a significant dependence on the choice of the renormalization scheme for the bottom quark Yukawa coupling.

We show that the standard model prediction for these ratios defined with the same cut on the dilepton mass for electron and muon modes, R-H=1+O(m(mu)(2)/m(b)(2)), has a much smaller theoretical uncertainty (less than or similar to1%) than the one for the individual branching fractions. The present experimental limit R(K)less than or equal to1.2 puts constraints on scalar and pseudoscalar couplings, which are similar to the ones from current data on B(B-s-->mu(+)mu(-)). We find that new physics corrections to R-K* and R-X s can reach 13% and 10%, respectively. C1 Univ Munich, Sekt Phys, D-80333 Munich, Germany. Tech Univ Munich, Dept Phys, D-85748 Garching, Germany.

Possible t-channel diagrams with K* exchange are considered in both reactions as well as K exchange in NN reactions. The cross section for np-->Lambda(0)Theta(+), which has not been considered in previous calculations, is found to be about a factor of 5 larger than that for np-->Sigma(0)Theta(+) due to the large coupling of the KNLambda interaction. The cross sections are obtained by setting g(KNTheta)=1 and varying the ratio of g(K*NTheta)/g(KNTheta) so that future experimental data can be used to estimate these couplings. We also find that the isospin relations hold for these reactions. C1 Yonsei Univ, Inst Phys & Appl Phys, Seoul 120749, South Korea.

The numerical model includes the initial optical field ionization of the plasma by an intense 100 fs laser pulse, taking into account above threshold ionization heating, particle collisions, and spatial effects. Gain is then calculated during the process of recombination as the plasma expands and cools. We show that by taking into account the non-Maxwellian nature of the electron distribution function in the plasma and its spatial distribution, high gain in the 2-->1 transition of Li III is feasible under certain initial conditions, even though initial estimates based on the energy absorption during the ionization predict very low gain. We characterize the behavior of the gain under different pumping parameters and initial plasma conditions. C1 Princeton Univ, Princeton, NJ 08540 USA.

In analogy with the violent relaxation process in self-gravitating systems and in the Euler equation of two-dimensional turbulence, the initial relaxation of the laser can be described by the statistical mechanics of an associated Vlasov equation. The laser field intensity and the electron bunching parameter reach a quasistationary value which is well fitted by a Vlasov stationary state if the number of electrons N is sufficiently large. Finite N effects (granularity) finally drive the system to Boltzmann-Gibbs statistical equilibrium, but this occurs on times that are unphysical (i.e., excessively long undulators). All theoretical predictions are successfully tested by means of finite- N numerical experiments. C1 Ecole Normale Super Lyon, CNRS, UMR 5672, Phys Lab, F-69364 Lyon 07, France.

Statistical fluctuations, that become significant as the number of particles diminishes, are responsible for this behavior. This phenomenon underlies a broad range of interacting particle systems including in particular multispecies annihilation processes. C1 Los Alamos Natl Lab, Div Theoret, Los Alamos, NM 87545 USA.

Due to the disorder, solitons emit radiation, i.e., the energy of the solitons is partly transferred into the delocalized modes. The radiation serves as a mediator of the intersoliton interaction leading to fluctuations of the soliton separations. We establish statistics of the fluctuations which is found to be sensitive to the phase mismatches and mutual polarizations of the solitons, and independent of the soliton separation.

We find a remarkably rich variety of dynamical locking phenomena as we vary the angle of the applied drive with respect to the orientation of the colloidal lattice. When the driven colloid locks to certain lattice symmetry directions, its motion is not necessarily aligned with the drive. Applying a transverse force to the driven particle can result in either increased or decreased drag in the driving direction, depending on the angle of the drive. The dynamical locking produces anomalies in both the longitudinal and the transverse velocity vs driving force curves, including steps and regimes of negative differential resistance. As the interaction of the driven particle with the surrounding lattice increases, significant distortion or dislocations in the surrounding media occur, and as a result the directional locking is enhanced. We compare these results to those obtained for driving particles over fixed substrates, and show that a far richer variety of behaviors occurs when the underlying lattice is allowed to distort. We discuss how this system can be used for particle species segregation when the onset of different locking angles occurs at different drives for varied particle charges. We also show that the most pronounced locking phases should be observable at temperatures up to the melting transition of the colloidal lattice.

The measurements were performed at 13- and 19-MA currents and 1-, 2-, 3-, and 4-mm gaps. The wire material, number of wires, wire-array diameter, wire-array length, wire-array-electrode design, normalized-pinch-current time history, implosion time, and diagnostic package were held constant for the experiments. To keep the implosion time constant, the mass of the array was increased as I-2 (i.e., the diameter of each wire was increased as I), where I is the peak pinch current. At 19 MA, the mass of the 300-wire 20-mm-diam 10-mm-length array was 5.9 mg. For the configuration studied, we find that to eliminate the effects of gap closure on the radiated energy, the width of the gap must be increased approximately as I. For shots unaffected by gap closure, we find that the peak radiated x-ray power P(r)proportional toI(1.24+/-0.18), the total radiated x-ray energy E(r)proportional toI(1.73+/-0.18), the x-ray-power rise time tau(r)proportional toI(0.39+/-0.34), and the x-ray-power pulse width tau(w)proportional toI(0.45+/-0.17). Calculations performed with a time-dependent model of an optically thick pinch at stagnation demonstrate that the internal energy and radiative opacity of the pinch are not responsible for the observed subquadratic power scaling. Heuristic wire-ablation arguments suggest that quadratic power scaling will be achieved if the implosion time tau(i) is scaled as I-1/3. The measured 1sigma shot-to-shot fluctuations in P-r, E-r, tau(r), tau(w), and tau(i) are approximately 12%, 9%, 26%, 9%, and 2%, respectively, assuming that the fluctuations are independent of I. These variations are for one-half of the pinch. If the half observed radiates in a manner that is statistically independent of the other half, the variations are a factor of 2(1/2) less for the entire pinch. We calculate the effect that shot-to-shot fluctuations of a single pinch would have on the shot-success probability of the double-pinch inertial-confinement-fusion driver proposed by Hammer [Phys. Plasmas 6, 2129 (1999)]. We find that on a given shot, the probability that two independent pinches would radiate the same peak power to within a factor of 1+/-alpha (where 0less than or equal toalpha<1) is equal to erf(alpha/2sigma), where sigma is the 1sigma fractional variation of the peak power radiated by a single pinch. Assuming alpha must be less than or equal to7% to achieve adequate odd-Legendre-mode radiation symmetry for thermonuclear-fusion experiments, sigma must be <3% for the shot-success probability to be greater than or equal to90%. The observed (12/2(1/2))%=8.5% fluctuation in P-r would provide adequate symmetry on 44% of the shots. We propose that three-dimensional radiative-magnetohydrodynamic simulations be performed to quantify the sensitivity of the x-ray emission to various initial conditions, and to determine whether an imploding z pinch is a spatiotemporal chaotic system.

Robust identification of malfunctioning BPMs plays an important role in any orbit or turn-by-turn analysis. Singular value decomposition and Fourier transform methods, which have evolved as powerful numerical techniques in signal processing, will aid in such identification from BPM data. This is the first attempt at RHIC to use a large set of data to statistically enhance the capability of these two techniques and determine BPM performance.

A Wien filter in the 100 keV beam line of the injector was used to vary the electron spin orientation exiting the injector. High statistical precision measurements of the scattering asymmetry as a function of the spin orientation were made with each polarimeter. Since each polarimeter receives beam with the same magnitude of polarization, these asymmetry measurements permit a high statistical precision comparison of the relative analyzing powers of the five polarimeters. This is the first time a precise comparison of the analyzing powers of Compton, Moller, and Mott scattering polarimeters has been made. Statistically significant disagreements among the values of the beam polarization calculated from the asymmetry measurements made with each polarimeter reveal either errors in the values of the analyzing power or failure to correctly include all systematic effects. The measurements reported here represent a first step toward understanding the systematic effects of these electron polarimeters. Such studies are necessary to realize high absolute accuracy (ca. 1%) electron polarization measurements, as required for some parity violation measurements planned at Jefferson Laboratory. Finally, a comparison of the value of the spin orientation exiting the injector that provides maximum longitudinal polarization in each experimental hall leads to an independent and very precise ( better than 10(-4)) absolute measurement of the final electron beam energy.

Long-range beam-beam interactions have been significant sources of beam loss and lifetime limitations of antiprotons. The dynamics due to the long-range beam-beam interactions depends on several beam parameters such as tunes, coupling, chromaticities, beam separations, intensities, and emittances. We have developed analytical tools to calculate, for example, amplitude dependent tune shifts and chromaticities, beam-beam induced coupling, and resonance driving terms. We report on these calculations and estimates of dynamic aperture and diffusion coefficients with long-term tracking. These theoretical results are compared with observations and used to predict performance at design values of beam parameters. C1 Fermilab Natl Accelerator Lab, Batavia, IL 60510 USA.

The set-up consists of 44 cubic crystals of natural TeO2, 5 cm on the side and 18 crystals of 3 x 3 x 6 cm(3). Four of these latter crystals are made with isotopically enriched materials: two in Te-128 and two others in Te-130. With a sensitive mass of similar to40 kg, our array is by far the most massive running cryogenic detector to search for rare events. The array is operated at a temperature of similar to10 mK in a dilution refrigerator under a heavy shield in the Gran Sasso Underground Laboratory at a depth of about 3500 m.w.e. The counting rate in the region of neutrinoless double beta decay is similar to0.2 counts keV(-1) kg(-1) y(-1), among the lowest in this type of experiment. No evidence for neutrinoless double beta decay is found with the present statistics obtained in about three months with a live time of 72%. The corresponding lower limit for the lifetime of this process is of 5.5 x 10(23) years at 90% C.L. The corresponding limit for the effective neutrino mass ranges between 0.37 to 1.9 eV depending on the theoretically calculated nuclear matrix elements used. This constraint is the most restrictive one except those obtained with Ge diodes, and is comparable to them. (C) 2004 Elsevier B.V. All rights reserved.

These may be formally regarded as either large eddy simulation or Reynolds-averaged Navier-Stokes models of turbulence. All of the turbulence closure models in the class under investigation preserve the existence of elliptic instability, although they shift its angle of critical stability as a function of the rotation rate Omega of the coordinate system, the wave number beta of the Kelvin wave, and the model parameter alpha, the turbulence correlation length. Elliptic instability allows a comparison among the properties of these models. It is emphasized that the physical mechanism for this instability is not wave-wave interaction, but rather wave, mean-flow interaction as governed by the choice of a model's nonlinearity.(C) 2004 American Institute of Physics.

Computed species distributions in a planar cross section of the jet are compared to planar laser-induced fluorescence images produced by the experiment. Given the qualitative nature of the published experimental images, the agreement with spatial flow features is quite good. We find that differential diffusion of species is an important feature of this experiment, leading to a significant decoupling of the helium and the biacetyl tracer.

The resulting Euler-Lagrange equations are solved analytically and numerically. The self-consistent solutions of whole Euler-Lagrange equations as well as both helicity and energy balance equations are obtained numerically for the given parameters and boundary conditions. It is found that for low and general aspect ratio tokamaks, there exist different typical minimum dissipation states, corresponding respectively to different typical current profiles observed in experiments. It is also found that there exist different types of relaxed states in the different regions of the, parameter space for a selected device. Each current profile mode is achieved by adjusting controllable parameters such as plasma resistivity, boundary toroidal magnetic field or boundary electric field. The results show that there exists a key parameter E-0/etaB(0) in determining the final relaxed states. The typical minimum dissipation state may evolve to other forms of states abruptly by increasing E-0/etaB(0) to be above a critical value. Three forms of current profile are presented for the low aspect ratio National Spherical Torus Experiment (NSTX) [M. Ono et al., Nucl. Fusion 40, 557 (2000)]. The first form peaks in the edge of the high field side similar to the typical experimental form. The second peaks in the central region on the equatorial plane. The third may have a hole or reverse in the central region. Both the second and third states could be obtained by increasing E-0/etaB(0) to be above the critical value.

Plasmas 9, 2221 (2002)] are presented. In this work, the effect of roughness imposed only on the surfaces of the inner shell is studied. Realistic perturbations are adopted from a measured spectrum of a glass capsule (as a surrogate for the high-Z inner shell). It is found that perturbing the inner surface of the inner shell shows minimal degradation in capsule performance. On the other hand, when roughness is imposed on the outer surface of the inner shell, the growth of large Legendre mode number perturbations (l>200) leads to shell breakup. Further analysis reveals a new pathway for the Rayleigh-Taylor (RT) instability. L-shell radiation (>8 keV) from the high-Z hohlraum wall ablates the outer surface of the high-Z inner shell, promoting large outward expansion which is reversed by the converging outer shell. The classic conditions for RT instability are met: low density material pushing onto the higher density inner shell. It is shown that this effect can be controlled by tamping the outward expansion of the inner shell with a variety of materials. Simulations with separate CH and Ti tampers demonstrate that the redesigned capsule can withstand perturbations with high mode number content without exhibiting shell breakup. Furthermore, the outstanding question of determining the cutoff mode number (l(c)) is addressed by performing simulations with successively larger maximum l, reaching values beyond 1000, and calculating the mix width of the pusher/tamper interface for the CH-tamped case. These numerical studies suggest that the mix width approaches a constant value close to 40% of the shell width at peak compression. While not a proof that l(c) has been found, this result suggests that a mix-relevant mode number may be within reach of current simulation capabilities. (C) 2004 American Institute of Physics.

These data, from the OMEGA [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)] laser system, show that the measured RT growth of mass perturbations was reduced when a picket pulse was used. The picket pulse and subsequent relaxation period, before the drive pulse, cause the foil to expand and rarefy, resulting in higher ablation velocities during the drive pulse and greater ablative stabilization. This effect was examined both computationally and experimentally for different picket-pulse intensities. (C) 2004 American Institute of Physics.

An experiment is planned to study the inverse-pinch configuration using the Zebra Z pinch [B. S. Bauer et al., AIP Conference Proceedings Vol. 409 (American Institute of Physics, Melville, 1997), p. 153] of the Nevada Terawatt Facility at the University of Nevada, Reno (UNR). The dynamics of the discharge formation have been analyzed using analytic models and numerical methods. Strong heating occurs by thermalization of directed energy when an outward moving current sheet (the inverse pinch effect) collides with the outer wall of the experimental chamber. Two-dimensional magnetohydrodynamic simulations show Rayleigh-Taylor and Richtmyer-Meshkov like modes of instability, as expected because of the shock acceleration during plasma formation phase. The instabilities are not disruptive, but give rise to a mild level of turbulence. The conclusion from this work is that an interesting experiment relevant to wall confinement for MTF could be done using existing equipment at UNR. (C) 2004 American Institute of Physics.

A. Paisner, J. D. Boyes, S. A. Kumpan, W. H. Lowdermilk, and M. S. Sorem, Laser Focus World 30, 75 (1994)] is examined. Sensitivity to target fabrication defects in spherical harmonics modes L less than or equal to 12 is quantified in terms of a mode dependent tolerance to surface perturbations. Simulations of NIF capsule implosions with single mode perturbations on a single surface allow the determination of modal growth factors. Simulations with large initial perturbations were also done to determine how large a final perturbation could be tolerated.

Ceres and Vesta are two complementary terrestrial protoplanets (one apparently "wet" and the other "dry"), whose accretion was probably terminated by the formation of Jupiter. They provide a bridge in our understanding between the rocky bodies of the inner solar system and the icy bodies of the outer solar system. Ceres appears to be undifferentiated while Vesta has experienced significant heating and likely differentiation. Both formed very early in the history of the solar system and while suffering many impacts have remained intact, thereby retaining a record of events and processes from the time of planet formation. Detailed study of the geophysics and geochemistry of these two bodies provides critical benchmarks for early solar system conditions and processes that shaped its subsequent evolution. Dawn provides the missing context for both primitive and evolved meteoritic data, thus playing a central role in understanding terrestrial planet formation and the evolution of the asteroid belt. Dawn is to be launched in May 2006 arriving at Vesta in 2010 and Ceres in 2014, stopping at each to make I I months of orbital measurements. The spacecraft uses solar electric propulsion, both in cruise and in orbit, to make most efficient use of its xenon propellant. The spacecraft carries a framing camera, visible and infrared mapping spectrometer, gamma ray/neutron spectrometer, magnetometer, and radio science. (C) 2003 Elsevier Ltd. All rights reserved.

Field-grown, nitrogen-fixing soybean with indeterminate flowering might therefore be expected to escape these limitations. Soybean was grown from emergence to grain maturity in ambient air (372 mumol mol(-1)[CO2]) and in air enriched with CO2 (552 mumol mol(-1)[CO2]) using Free-Air CO2 Enrichment (FACE) technology. The diurnal courses of leaf CO2 uptake (A) and stomatal conductance (g(s)) for upper canopy leaves were followed throughout development from the appearance of the first true leaf to the completion of seed filling. Across the growing season the daily integrals of leaf photosynthetic CO2 uptake (A') increased by 24.6% in elevated [CO2] and the average mid-day g(s) decreased by 21.9%. The increase in A' was about half the 44.5% theoretical maximum increase calculated from Rubisco kinetics. There was no evidence that the stimulation of A was affected by time of day, as expected if elevated [CO2] led to a large accumulation of leaf carbohydrates towards the end of the photoperiod. In general, the proportion of assimilated carbon that accumulated in the leaf as non-structural carbohydrate over the photoperiod was small (< 10%) and independent of [CO2] treatment. By contrast to A', daily integrals of PSII electron transport measured by modulated chlorophyll fluorescence were not significantly increased by elevated [CO2]. This indicates that A at elevated [CO2] in these field conditions was predominantly ribulose-1,5-bisphosphate (RubP) limited rather than Rubisco limited. There was no evidence of any loss of stimulation toward the end of the growing season; the largest stimulation of A' occurred during late seed filling. The stimulation of photosynthesis was, however, transiently lost for a brief period just before seed fill. At this point, daytime accumulation of foliar carbohydrates was maximal, and the hexose:sucrose ratio in plants grown at elevated [CO2] was significantly larger than that in plants grown at current [CO2]. The results show that even for a crop lacking the constraints that have been considered to limit the responses of C-3 plants to rising [CO2] in the long term, the actual increase in A over the growing season is considerably less than the increase predicted from theory.

The Arabidopsis genome encodes two homologues of Toc34, designated atToc33 and atToc34. In this report, we describe the identification and characterization of two atToc34 knockout mutants, plastid protein import 3-1 (ppi3-1) and ppi3-2. Aerial tissues of the ppi3 mutants appeared similar to the wild type throughout development, and contained structurally normal chloroplasts that were able to efficiently import the Rubisco small subunit precursor (prSS) in vitro. The absence of an obvious ppi3 phenotype in green tissues presumably reflects the ability of atToc33 to substitute for atToc34 in the mutant, and the relatively high level of expression of the atTOC33 gene in these tissues. In the roots, where atTOC33 is expressed at a much lower level, significant growth defects were observed in both mutants: ppi3 roots were approximately 20-30% shorter than wild-type roots. Attempts to identify a double homozygote lacking atToc34 and atToc33 (by crossing the ppi3 mutants with ppi1, an atToc33 knockout mutant) were unsuccessful, indicating that the function provided by atToc33/atToc34 is essential during early development. Plants that were homozygous for ppi1 and heterozygous for ppi3 displayed a chlorotic phenotype much more severe than that of the ppi1 single mutant. Furthermore, the siliques of these plants contained approximately 25% aborted seeds, indicating that the double homozygous mutation is embryo lethal. The data demonstrate that atToc33/atToc34 performs a central and essential role during plastid protein import, and indicate that the atToc34 isoform is relatively more important for plastid biogenesis in roots.

The advantage of synthetic imaging is that the image can be produced without the need for a large lens of high optical quality, and each frequency that is launched can be independently imaged. A particularly simple arrangement, consisting of a single receiver located at the midpoint of a microwave beam propagating along the plasma midplane is shown to suffice for imaging purposes. However, as the ratio of the parallel to poloidal correlation length decreases, a poloidal array of receivers needs to be used to synthesize the image with high accuracy. Simulations using DIII-D relevant parameters show the similarity of synthetic and optical imaging in present day experiments. C1 Princeton Plasma Phys Lab, Princeton, NJ 08543 USA.

Understanding and predicting the resulting stresses are crucial for robust design and safe operation of such devices. In this paper, closed-form expressions for the induced stresses in cylindrical rods subjected to rapid partial energy deposition have been directly derived; they are then used to estimate the highest stress of long cylindrical absorbers and to test the accuracy of thermal shock simulation using finite element analysis (FEA) codes. Characteristics of such stresses were discussed in detail. It was found that ANSYS may produce accurate details in thermal shock simulation if element size and time step used in the simulation model meet the criteria proposed by Zheng and co-workers in another paper.

Smaller particles typically lead to faster reactions and we have synthesized nano-scale WO3 using wet chemistry. Ammonium paratungstate was dissolved in acid. Tungstic acid was precipitated by addition to distilled water and the resulting powder was dried. Analysis by Xray diffraction, Raman spectroscopy and electron microscopy revealed hydrated WO3, having approximately 100 nm x 7 nm platelet morphology. Thermal treatment in air at 200degreesC or 400degreesC removed water, forming cubic or monoclinic WO3, respectively. Tungsten forms other stable oxides and we accessed WO2 by reducing WO3 in dilute H-2 at 650degreesC. Reaction performance of these WOx-materials, mixed with nano-Al at various stoichiometries, is reported. Open-tray burn velocity reached 250 m/s. Pressure cell experiments found a maximum pressure of 1.45 MPa and maximum pressurization rate of 500 GPa/s. These maximum pressures and rates occurred very near a stoichiometric mixture of the Al and WO3. C1 Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

Spectral features due to Al and AlO species were observed on top of an apparent thermal background. The intensity of the AlO emission was observed to change with the ratio Al/MoO(3), with larger AlO intensities associated with faster wave propagation speeds. Absolute irradiance output from the compressed powder samples was found to exceed that from a tungsten filament at the same apparent temperature. C1 Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

To fix this, the Gurney analysis is used, but this results in low values for full-wall standard, ideal explosives relative to CHEETAH analyses. A new constant metal-density model is suggested, which takes account of the thinning metal wall as the cylinder expands. With this model, the inner radius of the metal cylinder moves faster than the measured outer radius. Additional small corrections occur in all cylinders because of energy trapped in the copper walls. Also, the half-wall cylinders have a small correction because the relative volumes of the gas products are smaller at a given outside wall displacement. The Fabry-Perot and streak camera measurements are compared. The Fabry method is shown to equate to the constant density model.

One of the popular tools used for the database search is SEQUEST Peptide identification is carried out by selecting SEQUEST hits above a specified threshold, the value of which is typically chosen empirically in an attempt to separate true identifications from false ones. These SEQUEST scores are not normalized with respect to the composition, length and other parameters of the peptides. Furthermore, there is no rigorous reliability estimate assigned to the protein identifications derived from these scores. Hence, the interpretation of SEQUEST hits generally requires human involvement, making it difficult to scale up the identification process for genome-scale applications. To overcome these limitations, we have developed a method, which combines a neural network and a statistical model, for normalizing SEQUEST scores, and also for providing a reliability estimate for each SEQUEST hit. This method improves the sensitivity and specificity of peptide identification compared to the standard filtering procedure used in the SEQUEST package, and provides a basis for estimating the reliability of protein identifications.

The average diameter of a large sample of monodisperse fluid drops was determined by measuring their terminal velocity in air, or if charged, their motion under the influence of an electric field, as well as by measurement of the magnitude of their Brownian motion. The diameter of individual drops was determined optically, by direct observation using an imaging system based on a charge-coupled-device camera. The technique used to analyze the image data is based on a best-fit technique taking the point spread function of the lens into account, and yields results accurate to 1% (based on a single image) without the need for any calibration. By combining this technique with terminal velocity measurements, the density of the fluid can be determined to similar accuracy. (C) 2004 American Institute of Physics.

Temperature measurements using spectroscopy of the shocked D-2 self-emission can help discriminate between different deuterium equation of state models. Time-resolved spectra are recorded using four diagnostic systems, each composed of a fiber optic probe that transmits light from the shocked D-2 to a remote streaked spectrometer. Calibration of the entire system in the streaked mode is performed using a xenon arc lamp. The absolute xenon arc lamp spectrum is determined by comparison with National Institute of Standards and Technology (NIST) standards. Data analysis is performed by measuring the wavelength-dependent efficiency for each system and applying this to determine the shocked D-2 self-emission spectrum. Temperature is deduced from either the wavelength dependence of the spectral radiance, ignoring the absolute intensity, or from both the wavelength dependence and the absolute intensity. The shocked D-2 temperature uncertainties obtained with the methods described here are well below the differences between D-2 equation of state (EOS) models and these measurements should therefore provide new insight into D-2 EOS physics.

Parameters of the plasma and ion beam were measured as a function of magnetic field. The extracted ion current shows a nonmonotonic behavior as function of magnetic field strength but the magnetic field distribution had only little influence on the current-voltage characteristics and on all other derived plasma and beam parameters. Analysis of our experimental conditions indicates that the observed nonmonotonic behavior is associated with a change in the ratio of electron Larmor radius to cathode sheath thickness.

The instrument involves the coupling of a high resolution laboratory x-ray powder diffractometer, a helium flow cryostat, and a split-coil superconducting magnet allowing for in situ structural studies in a magnetic field between 0 to 35 kOe, and a temperature between 2.2 to 315 K. The data collected from a copper sample, which is used as a standard, at temperatures down to 4.3 K and in fields up to 10 kOe are presented. The ability to image massive magnetic field induced structural transformations is demonstrated utilizing powder diffraction data of Gd5Ge4 collected under both isothermal and isofield conditions at various temperatures below 15 K and magnetic fields up to 35 kOe.

Bimaterial microcantilevers deform as their temperature changes due to the absorption of infrared photons. Infrared imaging using uncooled cantilever arrays has already been achieved by a number of groups. In this paper, we examined the performance of microcantilevers as uncooled infrared detectors with optical readout. As in the case of other kinds of uncooled thermal infrared detectors, temperature fluctuation noise and background fluctuation noise are fundamental limits to the performance of microcantilever thermal detectors. Since microcantilevers are mechanical devices, thermo-mechanical noise will also influence their performance. We fabricated a SiNx microcantilever thermal detector with an Al layer in the bimaterial region. For the microcantilever geometry and materials used, the background fluctuation noise equivalent temperature difference, NETDBF, calculated for f/1 optics and a 30 Hz frame rate was found to be 1.26 mK. The NETDTF, limited by temperature fluctuation noise, was calculated to be 7.4 mK while the thermo-mechanical NETDTM was calculated to be 5.3 mK. The sum of all fundamental noise sources, including the intrinsic noise of the "optical lever" readout, results in a total NETD of 9.2 mK. Absence of the readout noise would improve this parameter by only 2%. (C) 2004 American Institute of Physics. C1 Oak Ridge Natl Lab, Oak Ridge, TN 37831 USA. Univ Tennessee, Knoxville, TN 37996 USA.

Fulfillment of the requirements for limiting dose to the public, which includes containment of the radioactive waste emplaced in the proposed repository and subsequent slow release of radionuclides from the Engineered Barrier System (EBS) into the geosphere, will rely on a robust waste container design, among other EBS components. Part of the evaluation process involves sensitivity studies aimed at elucidating which model parameters contribute most to the waste package and overlying drip shield degradation characteristics. The model parameters identified for this study include (1) general corrosion rate parameters and (2) stress corrosion cracking (SCC) parameters. Temperature dependence and parameter uncertainty are evaluated for the general corrosion rate model parameters while for the SCC model parameters, uncertainty treatment of stress intensity factor, crack initiation threshold, and manufacturing flaw orientations are evaluated. Based on these evaluations new uncertainty distributions are generated and recommended for future analyses. Also, early waste package failures due to improper heat treatment were added to the waste package degradation model. The results of these investigations indicate that the waste package failure profiles are governed by the manufacturing flaw orientation model parameters.

The technique can image and measure brazing filler metal flow velocities, positions, contact angles, and fillet shape. The system captures the two-dimensional fluid flow kinetics common in most capillary driven processes. It consists of a fully integrated, digital, closed loop heating station and a high speed digital camera. The apparatus provides an accessible approach for gathering dynamic braze wetting and flow data that are normally difficult to obtain in a furnace environment. Braze flow displacement curves are generated from the processed camera images. The flow data are being used to calibrate and validate a braze flow model that will predict the effects of dissolution, diffusion, compositional changes, and solidification on capillary fill and fillet geometry.

Images of the trailing edge of a weld pool (solid liquid interface) were collected during the welding process. Weld ripple formation was observed and the associated solid liquid interface velocity was measured. A distinct sequence of events was observed each time a ripple formed. This sequence of events involved apparent changes in the solid liquid interface velocity, dendrite morphology, and dendrite growth direction. The microstructures of a group of rippled welds were examined and a number of features associated with the rippling phenomenon were identified. These features included changes in the pattern of the interdendritic constituents and changes in the solute distribution across the ripple feature. This information coupled with the video images was used to explain more fully the weld rippling phenomenon and the origins of microstructural changes associated with it. It is shown that solute redistribution occurs in the weld on a length scale associated with the ripple features. C1 Sandia Natl Labs, Albuquerque, NM 87123 USA.

To explain the basic physical phenomena at the basis of this experiment, we have developed a non-equilibrium Green's function model for the electron transport problem inside the device structure. Following a semi-empirical approach, we have developed a formulation to express the drag rate inclusive of radiation power absorption and Coulomb drag effects, starting from an existing approach for coupled wells in the absence of radiation. A single calibration factor is evaluated for one experimental condition and left unchanged for all other situations examined. The simulation results follow closely the measured data in the range of frequencies and temperatures covered by the experiments. C1 Univ Illinois, Beckman Inst, Urbana, IL 61801 USA.

Comparison of the measured THz resonant photoresponse to the calculated THz absorption spectrum establishes that the resonances are determined by standing plasma waves in the DQW channel under metallic portions of the grating gate. It is found theoretically that the DQW asymmetry mixes the acoustic and optical plasmons resulting in a rather intense ac electric field between the QWs.

Measuring the conductance of one wire, as the width of the other is varied, we observe a resonant peak in its conductance that is correlated with the point at which the swept wire pinches off. We discuss this behaviour in terms of recent theoretical predictions concerning local spin-moment formation in quantum wires.

Its reliable production has opened the possibility for use in both basic and clinical investigations and also in pairing it with other more biologically specific positron emission tomography tracers to provide an important functional perspective to the measurement. In this article, we highlight examples in which (18)FDG is paired with another carbon-11- or fluorine-18-labeled radiotracer in the same subject to correlate neurotransmitter-specific effects with regional metabolic effects using the human brain as a model.

Unfortunately, the extent to which biologists can take advantage of these modeling techniques is limited by the computational complexity of gene regulatory network simulation algorithms. This study presents a new platform-independent, grid-based distributed computing environment that accelerates biological model simulation and, ultimately, development. Applying this environment to gene regulatory network simulation shows a significant reduction in execution time versus running simulation jobs locally. To analyze this improvement, a performance model of the distributed computing environment is built. Although this grid-based system was specifically developed for biological simulation, the techniques discussed are applicable to a variety of simulation performance problems.

The aim of the CEP was to provide University campuses with site-specific assessments of their earthquake strong motion exposure, to complement estimates they obtain from consultants according to the state-of-the-practice (SOP), i.e. Building Codes (UBC 97, IBC 2000), and Probabilistic Seismic Hazard Analysis (PSHA). The Building Codes are highly simplified tools, while the more sophisticated PSHA is still somewhat generic in its approach because it usually draws from many earthquakes not necessarily related to the faults threatening the site under study. Between 1996 and 2001, the site-specific studies focused on three campuses: Riverside, San Diego, and Santa Barbara. Each campus selected 1-3 sites to demonstrate the methods and procedures used by the CEP: Rivera Library and Parking Lots (PL) 13 and 16 at UCR, Thornton Hospital, the Cancer Center, and PL 601 at UCSD, and Engineering I building at UCSB. The project provided an estimate of strong ground motions at each selected site, for selected earthquake scenarios. These estimates were obtained by using an integrated geological, seismological, geophysical, and geotechnical approach, that brings together the capabilities of campus and laboratory personnel. Most of the site-specific results are also applicable to risk evaluation of other sites on the respective campuses. The CEP studies have provided a critical assessment of whether existing campus seismic design bases are appropriate. Generally speaking, the current assumptions are not acknowledging the severity of the majority of expected motions. Eventually, both the results from the SOP and from the CEP should be analyzed, to arrive at decisions concerning the design-basis for buildings on UC campuses. Published by Elsevier Ltd.

Furthermore, the owner of the system model often has no design authority or interest in some components other than their effects on the remaining system. Frequency dependent stiffness and damping for these components can also significantly add to the modeling difficulty. This article describes a process for combining test-based and finite element-based models in NASTRAN that circumvents many of these limitations. Advantages of including test-based models within a complex system model include: (1) It is generally faster and more accurate to develop a test-based model than a finite element-based model; (2) Computer run times and computer resources are reduced; and (3) Minimizing errors, which are frequently present in complex system models, is possible. In this combined analysis approach, test-based models are determined using admittance modeling. A test-based model for the component's dynamics is derived at the locations where it interfaces with the system finite element model. This model is then converted into a NASTRAN readable format and analytically coupled to the finite element model, enabling prediction of the combined system response. Several examples are presented to demonstrate the efficacy of this approach. C1 Sandia Natl Labs, Albuquerque, NM 87185 USA.

S. Department of Energy's Richland Operations Office has initiated efforts to adapt and implement the features, events, and processes (FEP) methodology used in scenario development for nuclear waste disposal programs to the environmental management and remediation problems facing the Hanford site. These efforts have shown that modification of the FEPs methodology to incorporate the use of process relationship diagrams (PRD) is effective in facilitating the development of conceptual models and selection of potentially relevant factors (i.e., FEPs) to be incorporated into a specific environmental assessment. In adopting this methodology for Hanford, a master PRD was created to provide a structure to identify these factors and to illustrate the relationships among them. The organizational framework of the master PRD was developed to match the organization of current Hanford site-wide environmental assessment activities and to facilitate screening of the FEPs relevant to the specific assessments needed for the site.

Rapid mounting and dismounting of the samples increases the efficiency of the crystal screening and data collection processes, where many crystals can be tested for the quality of diffraction. The sample-mounting subsystem has random access to 112 samples, stored under liquid nitrogen. Results of extensive tests regarding the performance and reliability of the system are presented. To further increase throughput, we have also developed a sample transport/storage system based on "puck-shaped" cassettes, which can hold sixteen samples each. Seven cassettes fit into a standard dry shipping Dewar. The capabilities of a robotic crystal mounting and alignment system with instrumentation control software and a relational database allows for automated screening and data collection to be developed.

The crystal structure of Pta from the methane-producing archaeon Methanosarcina thermophila, representing the first crystal structure of any Pta, was determined by multiwavelength anomalous diffraction at 2.7 Angstrom resolution. In solution and in the crystal, the enzyme forms a homodimer. Each monomer consists of two alpha/beta domains with a cleft along the domain boundary, which presumably contains the substrate binding sites. Comparison of the four monomers present in the asymmetric unit indicates substantial variations in the relative orientation of the two domains and the structure of the putative active site cleft. A search for structural homologs revealed the NADP(+)-dependent isocitrate and isopropylmalate dehydrogenases as the only homologs with a similar two-domain architecture.

The performance of MgB2 films at microwave frequencies has so far been rather poor compared to that of Nb alloys and this may result from intrinsic behaviour related to the double-gap structure or extrinsic properties due to non-optimized thin films. Here we give a detailed report on the microwave magnetic field dependent surface impedance of an MgB2 thin film, using a parallel plate resonator, as a function of temperature. We discuss whether the framework used to analyse nonlinear behaviour for other superconductors, both low and high T-c, but single-gap, has any validity for MgB2 and whether the films are limited by intrinsic or extrinsic behaviour. The key result is the observation of junction-type switching effects at high microwave power.

This offers a mathematically sound basis for reducing complex kinetics. Computational investigation of such slow manifolds in inhomogeneous reaction systems undergoing diffusion in addition to chemical reaction is the subject of this paper. We perform simulations of a one-dimensional diffusion-reaction system from random non-premixed initial conditions to study the accessed composition space for a variety of diffusion to reaction time scale ratios. A detailed hydrogen-oxygen chemical kinetic set (6 species, 14 reactions) is used. Our results show that, to first order, the effect of random advection and diffusion is merely to increase the accessed state-space dimensionality over that of the WSR by the number of relevant mixture fractions. Circumstances under which the above simplification is not accurate are also identified. C1 Texas A&M Univ, Dept Aerosp Engn, College Stn, TX 77843 USA.

To allow the use of IR laser diodes, an IR absorber has to be added to the polymer. As a measure of the energy released during ablation of such polymers, the shockwave velocity in air is measured with shadowgraphy. The measured shockwave velocities of a cross-linked glyzidyl azide polymer (GAP) incorporating carbon particles (as broad range absorber), reveal that the shockwave velocity decreases with the increasing irradiation wavelength (193-1064 nm) for a given fluence. In addition, the shadowgraph images reveal that for irradiation with shorter wavelengths, the amount of solid fragments decreases and more gaseous products are released. Comparing the shockwave propagation of GAP and a triazene polymer reveals that both polymers exhibit similar shockwave velocities at UV irradiation wavelength, whereas with 1064 nm irradiation, the shockwaves generated using GAP propagate faster. These results are probably due to the change of the absorption site, the mechanism of ablation, and the different decomposition enthalpies. (C) 2003 Elsevier B.V. All rights reserved.

The model uses the common multiphase flow extension of Darcy's equation, and does not include gravity and capillarity effects. Under these conditions, the mathematical problem reduces to a 2 x 2 system of conservation laws whose essential features are: ( 1) the system is strictly hyperbolic; ( 2) both characteristic fields are nongenuinely nonlinear, with single, connected inflection loci. These properties, which are natural extensions of the two-phase flow model, ensure that the solution is physically sensible. We present the complete analytical solution to the Riemann problem ( constant initial and injected states) in detail, and describe the characteristic waves that may arise, concluding that only nine combinations of rarefactions, shocks and rarefaction-shocks are possible. We demonstrate that assuming the saturation paths of the solution are straight lines may result in inaccurate predictions for some realistic systems. Efficient algorithms for computing the exact solution are also given, making the analytical developments presented here readily applicable to interpretation of lab displacement experiments, and implementation of streamline simulators.

In LST technology, a pulsating laser beam is used to create thousands of arranged microdimples on a surface by a material ablation process. These dimples generate hydrodynamic pressure between oil-lubricated parallel sliding surfaces. The impact of LST on lubricating-regime transitions was investigated in this study. Tribological experiments were carried out on pin-on-disk test apparatus at sliding speeds that ranged front 0.15 to 0.75 m/s and nominal contact pressures that ranged front 0.16 to 1.6 MPa. Two types of oil with different viscosities (54.8 cSt and 124.7 cSt at 40degreesC) were evaluated its lubricants. Electrical resistance between flat-pin and laser-textured disks was used to determine the operating lubrication regime. The test results showed that laser texturing expanded the range of speed-load parameters for hydrodynamic lubrication. LST also reduced the measured friction coefficients of contacts that operated tinder the hydrodynamic regime. The beneficial,effects of laser surface texturing tire more pronounced tit higher speeds and loads and with higher viscosity oil. C1 Argonne Natl Lab, Div Energy Technol, Argonne, IL 60439 USA.

This paper presents a simple single frequency ultrasonic measurement technique that demonstrates the ability of ultrasonic sensors to measure slurry concentration. Sensor calibration data show that in this attenuation regime ultrasonic signal attenuation is proportional to the applied frequency and to the slurry volume fraction. Real-time measurements of ultrasonic signal attenuation were used to track the process of slurry mixing using single sensors and sensor arrays. Results from two experiments show the use of real-time measurements of ultrasonic signal attenuation to track the process of slurry mixing in situ and to track the ability to maintain a well-mixed steady state condition. Comparison of concentration means of the ultrasonic measurements with concentration means obtained from discrete extractive measurements show that the distributions overlap and cannot be statistically distinguished. The real-time ultrasonic sensor can be used as a primary measurement method or to reduce reliance upon extractive methods to measure slurry density and solids concentration.

The mechanical-resonance frequencies of a piezoelectric solid depend on all of the elastic and piezoelectric coefficients, and their accurate measurement allows one to determine the elastic and piezoelectric coefficients simultaneously. Resonance-peak-width measurements yield the internal-friction tensor. Successful determination requires correct vibration-mode identification for the observed resonance frequencies. This is achieved unambiguously by measuring deformation distributions on the vibrating-specimen surface with laser-Doppler interferometry and comparing them with calculated displacement distributions. The methodology is applied to lithium niobate (LiNbO3) and langasite (La3Ga5SiO14) crystals. (C) 2004 Elsevier B.V. All rights reserved.

The grating surface is in contact with the liquid or slurry. The ultrasonic beam, traveling in the solid, strikes the back of the grating and produces a transmitted m = 1 beam in the liquid. The angle of this beam in the liquid increases with decreasing frequency and the critical frequency F-CR occurs when the angle is 90degrees. At frequencies below F-CR, this m = 1 wave does not exist and its energy is shared with other types of waves. The signal of the reflected m = 0 wave is observed and an increase is observed at F-CR. This information yields the velocity of sound in the liquid and particle size. (C) 2004 Elsevier B.V. All rights reserved. C1 Pacific NW Natl Lab, Richland, WA 99352 USA.

The sensor transducers are mounted directly upon the stainless steel wall and the pipeline wall becomes part of the measurement system. Multiple reflections within the stainless steel wall are used to determine the acoustic impedance of the liquid, where the acoustic impedance is defined as the product of the density and the speed of sound. The probe becomes self-calibrating because variations in the pulser voltage do not affect the measurements. This feature leads to the stability of the measurements and the instrument requires much less time and effort to calibrate. Further, the calibration remains constant in time, because it does not depend upon the pulser voltage remaining at a given value. By basing the measurement upon multiple reflections, the sensitivity of the measurement is significantly increased. For slurries with wt% solids concentration of 1%, or less, high sensitivity is gained by analyzing attenuation measurements obtained from multiple paths through the slurry. For slurries with higher concentrations of solids, sufficient sensitivity is obtained by analyzing data from a simple transmission. Data are presented that show probe performance for each of these cases: very dilute and highly concentrated kaolin clay slurries. (C) 2004 Published by Elsevier B.V.

However, MP-NAT is limited in its ability to detect preseroconversion samples with very low viral RNA loads. Materials and Methods To determine whether a red blood cell unit, from an MP-NAT-negative donation, transmitted HIV when transfused to a patient, we compared the viral sequences from the blood donor and recipient. The implicated donation was also tested by commercially available NAT assays at a range of dilution factors to determine whether the infectious unit could have been detected using individual-donation NAT (ID-NAT). Results Phylogenetic linkage of HIV sequences in the blood donor and recipient confirmed the transmission of HIV by blood transfusion, the first such case identified since introduction of MP-NAT screening in 1999. Viral RNA was reliably detected by ID-NAT, but only inconsistently detected by MP-NAT. Conclusions Even following the introduction of MP-NAT, a preseroconversion donation with a viral load of less than or equal to 150 copies of RNA/ml went undetected and resulted in an HIV transmission.

Adsorption experiments conducted with Hanford formation sediment and groundwater spiked with dissolved I-125 (as an analog tracer for I-129) indicated that iodide adsorption was very low (0.2 mL/g) at pH 7.5 and could be represented by a linear isotherm up to a total concentration of 100 mg/L dissolved iodide. The results of desorption experiments revealed that up to 60% of adsorbed iodide was readily desorbed after 14 days by iodide-free groundwater. Because iodide adsorption was considered to be partially reversible, even though small amount of initial iodide is retarded by adsorption at mineral-water interfaces, the weak adsorption affinity results in release of iodide when iodide-free pore waters and uncontaminated groundwaters contact the contaminated sediments in the vadose zone and aquifer systems.

The erodent particles, 390 mum angular Al2O3, impacted at 30, 60, or 90degrees at a velocity of 50, 70, or 100 m/s. Steady-state erosion rates (ER) were obtained and the material-loss mechanisms were studied by scanning electron microscopy (SEM). The geopolymer responded to normal impact as a classically brittle material. Elastic-plastic indentation events led to formation of brittle lateral cracks that resulted in loss of materials erosion rate was proportional to erodent velocity to the 2.3 power. Impact at 60degrees produced similar results, with the erosion rates being in general slightly lower. Impact at 30degrees led to anomalously high erosion rates that were approximately independent of velocity. This response was attributed to presence of microcracks in the matrix and chipping of aggregates through propagation of radial cracks. (C) 2003 Elsevier B.V. All rights reserved.

These studies were applied to Xcel Energy (in Minnesota) and PacifiCorp and the Bonneville Power Administration (both in the northwestern United States). Although the approaches vary, three utility time frames appear to be most at issue: regulation, load following and unit commitment. This article describes and compares the analytic frameworks from recent analysis and discusses the implications and cost estimates of wind integration. The findings of these studies indicate that relatively large-scale wind generation will have an impact on power system operation and costs, but these impacts and costs are relatively low at penetration rates that are expected over the next several years.

The purpose of this paper is to review techniques that can be used to study the mesoscopic crystallographic structure of grain boundary networks and to summarize current findings. Recent studies have shown that grain surfaces within dense polycrystals favor the same low energy planes that are found on equilibrium crystal shapes and growth forms of crystals in contact with another phase. In the materials for which comprehensive data exists, the distribution of grain boundaries is inversely correlated to the sum of the energies of the surfaces of the grains on either side of the boundary.

Small additions of Ti decrease the contact angle of Sn-3 wt.% Ag alloys on alumina from 150degrees to 25degrees. However, a wide variability in contact angles and spreading rates is observed. The variability is related to the kinetics of Ti dissolution in the alloy and the formation of triple-line ridges. Enhanced spreading is not accompanied by the formation of a continuous reaction layer at the metal/ceramic interface. Furthermore, no reaction product could be detected after tests performed at temperatures below 800 degreesC. The average mechanical strength of metal-ceramic bonds fabricated under parallel conditions ranged between 40-110 MPa. In all cases, fracture of the joints occurred at the metal-ceramic interface. The formation of a discontinuous reaction product decreases the strength of the bonds fabricated at higher temperatures.

The detector can count x-rays at rates of 10(7) photons s(-1), giving good estimates of the RXMS at superlattice Bragg peaks in a reasonably short time when count losses due to the time structure of the synchrotron x-rays are corrected for. RXMS superlattice Bragg peaks as small as 1 x 10(-4) in flipping ratio have been measured from a Co/Cu multilayer at the K absorption edge of Cu. The data are fitted by an oscillatory model magnetization profile in the Cu layers derived from a Ruderman-Kittel-Kasuya-Yosida theory of exchange coupling adapted to a planar geometry.

For three different polyene series, the intense, visible d-->pi* metal-to-ligand charge-transfer bands unexpectedly blue-shift as the number of E-ethylene units (n) increases from 1 to 3, and the static first hyperpolarizabilities beta(0) determined via hyper-Rayleigh scattering and Stark spectroscopy maximize at n = 2, in marked contrast to other known D-A polyenes in which beta(0) increases steadily with n. Time-dependent density-functional theory and finite field calculations verify these empirical trends, which arise from the orbital structures of the complexes. This study illustrates that transition metal-based nonlinear optical chromophores can show very different behavior when compared with their more thoroughly studied purely organic counterparts.

Also, the correct 1/R asymptotic behavior of CT states with respect to a distance coordinate R between the separated charges of the CT state is not reproduced by TDDFT employing these xc-functionals. Here, we demonstrate by analysis of the TDDFT equations that the first failure is due to the self-interaction error in the orbital energies from the ground-state DFT calculation, while the latter is a similar self-interaction error in TDDFT arising through the electron transfer in the CT state. Possible correction schemes, such as inclusion of exact Hartree-Fock or exact Kohn-Sham exchange, as well as aspects of the exact xc-functional are discussed in this context. Furthermore, a practical approach is proposed which combines the benefits of TDDFT and configuration interaction singles (CIS) and which does not suffer from electron-transfer self-interaction. The latter approach is applied to a (1,4)-phenylene-linked zincbacteriochlorin-bacteriochlorin complex and to a bacteriochlorophyll-spheroidene complex, in which CT states may play important roles in energy and electron-transfer processes. The errors of TDDFT alone for the CT states are demonstrated, and reasonable estimates for the true excitation energies of these states are given.

Analytical performance of these sampling strategies was compared by using 213 nm laser ablation ICP-MS. A geological rock (Tuff) was quantitatively analyzed based on NIST series 610-616 glass standard reference materials. Laser ablation data were compared to ICP-MS analysis of the dissolved samples. The scan strategy (50 mum/s) produced a flat, steady temporal ICP-MS response whereas the single spot strategy produced a signal that decayed with time (after 60 s). Single-spot sampling provided better accuracy and precision than the scan strategy when the first 15 s of the sampling time was eliminated from the data analysis. In addition, the single spot strategy showed less matrix dependence among the four NIST glasses. (C) 2004 Elsevier B.V. All rights reserved. C1 Lawrence Berkeley Natl Lab, Berkeley, CA 94720 USA.

This laboratory has recently reported the construction and characterization of a linear time-of-flight mass spectrometer (ToF-MS) utilizing a radio frequency glow discharge ionization source. Data acquisition and analysis was performed using a digital oscilloscope and Microsoft Excel, respectively. Presently, no software package is available that is specifically designed for time-of-flight mass spectral analysis that is not instrument dependent. While spreadsheet applications such as Excel offer tremendous utility, they can be cumbersome when repeatedly performing tasks which are too complex or too user intensive for macros to be viable. To address this situation and make data analysis a faster, simpler task, our laboratory has developed a Microsoft Windows-based software program coded in Microsoft Visual Basic. This program enables the user to rapidly perform routine data analysis tasks such as mass calibration, plotting and smoothing on x-y data sets, In addition to a suite of tools for data analysis, a number of calculators are built into the software to simplify routine calculations pertaining to linear ToF-MS. These include mass resolution, ion kinetic energy and single peak identification calculators. A detailed description of the software and its associated functions is presented followed by a characterization of its performance in the analysis of several representative ToF-MS spectra obtained from different GD-ToF-MS systems.

The relaxation kinetics were initiated using a laser-induced temperature jump and probed using time-resolved infrared spectroscopy. The kinetics monitored within the amide I' absorbance of the polypeptide backbone exhibit two distinct kinetics phases with nanosecond and microsecond relaxation times. The fast kinetics relaxation time is close to the diffusion limits placed on protein folding reactions. The fast kinetics phase is dominated by the relaxation of the solvated helix (nu = 1632 cm(-1)), which reports on the fast relaxation of the individual helices. The slow kinetics phase follows the cooperative relaxation of the native helical bundle core that is monitored by both solvated (nu = 1632 cm(-1)) and buried helical IR bands (nu = 1652 cm(-1)). The folding rates of the slow kinetics phase calculated over an extended temperature range indicate that the core formation of this protein follows a pathway that is energetically downhill. The unfolding rates are much more strongly temperature-dependent indicating an activated process with a large energy barrier. These results provide significant insight into the primary process of protein folding and suggest that fast formation of helices can drive the folding of helical proteins.

The dependence of the limiting current, i(lim), on the rotation rate of the RDE was found to display classical Levich behavior up to potentials well within the range in which Au forms a surface oxide in the neat (sulfite-free) supporting electrolyte. However, simultaneous in situ NNI-UVRS measurements performed at lambda = 500 nm during sulfite oxidation failed to show any evidence for the presence of oxide on the Au surface within that entire potential range. Polarization of the Au RDE at more positive potentials led to a sudden drop in i(lim), ca. an order of magnitude, which correlated with an abrupt decrease in the intensity of the reflected light, consistent with formation of (one or more forms of) Au oxide on the surface. On the basis of these and other observations a model has been proposed in which sulfite reacts chemically with adsorbed oxygen on the surface (oxygen atom transfer) in the region that precedes partial inhibition. As the potential is increased, adsorbed oxygen undergoes Au-O place exchange forming two-dimensional nuclei on the surface, which undergo rapid (autocatalytic) growth, covering an area large enough to block significantly sulfite oxidation.

The observations were made at downstream distances of around 25 and 15 lunar radii (R-L), respectively. Both encounters occurred prior to the spacecraft entering the lunar shadow; one event took place within the magnetosheath. A characteristic feature of the lunar wake is the presence of two counterstreaming ion beams drawn in from either flank. We find that both ion components exhibit an extreme temperature anisotropy, often with T(perpendicular to)similar to10T(parallel to). The anisotropy is greatest in the central wake region. It appears that the anisotropy arises through the conservation of adiabatic invariants as solar wind plasma expands to fill in the cavity behind the Moon. Despite their large anisotropy, the proton distributions appear stable to the cyclotron instability. Correlated field and flow directional changes show that the wake geometry is dependent upon the prevailing magnetic field orientation. C1 MIT, Ctr Space Res, Cambridge, MA 02139 USA.

Cu(II) binding to ethylene diamine core poly(amidoamine) dendrimers in aqueous solutions SO LANGMUIR LA English DT Article ID X-RAY-ABSORPTION; POLY(PROPYLENE IMINE) DENDRIMERS; STARBURST DENDRIMERS; METAL NANOPARTICLES; MASS-SPECTROMETRY; COPPER(II) IONS; ENCAPSULATED PD; COMPLEXES; EPR; NANOCLUSTERS AB This paper describes an investigation of the uptake of Cu(II) by poly(amidoamine) (PAMAM) dendrimers with an ethylenediamine (EDA) core in aqueous solutions. We use bench scale measurements of proton and metal ion binding to assess the effects of W metal ion-dendrimer loading, (ii) dendrimer generation/ terminal group chemistry, and (iii) solution pH on the extent of binding of Cu(II) in aqueous solutions of EDA core PAMAM dendrimers with primary amine, succinamic acid, glycidol, and acetamide terminal groups. We employ extended X-ray absorption fine structure (EXAFS) spectroscopy to probe the structures of Cu(II) complexes with Gx-NH2 EDA core PAMAM dendrimers in aqueous solutions at pH 7.0. The overall results of the proton and metal ion binding measurements suggest that the uptake of Cu(II) by EDA core PAMAM dendrimers involves both the dendrimer tertiary amine and terminal groups. However, the extents of protonation of these groups control the ability of the dendrimers to bind Cu(II). Analysis of the EXAFS spectra suggests that Cu(II) forms octahedral complexes involving the tertiary amine groups of Gx-NH2 EDA core PAMAM dendrimers at pH 7.0. The central Cu(II) metal ion of each of these complexes appears to be coordinated to 2-4 dendrimer tertiary amine groups located in the equatorial plane and 2 axial water molecules. Finally, we combine the results of our experiments with literature data to formulate and evaluate a phenomenological model of CUM) uptake by Gx-NH2 PAMAM dendrimers in aqueous solutions. At low metal ion-dendrimer loadings, the model provides a good fit of the measured extent of binding of Cu(II) in aqueous solutions of G4-NH2 and G5-NH2 PAMAM dendrimers at pH 7.0.

This allowed us to quantify the adsorption parameters and to estimate the sticking coefficient. The sticking coefficient initially increases with TNT exposure time and then levels off around 0.3. Atomic force microscopy images of silicon surfaces exposed to TNT revealed "island" formation of the adsorbate on the silicon surface. At low exposure times, mainly the number density of islands increased with exposure time; at longer exposure times, the size (in particular, height) of the islands grew, corresponding to the higher sticking coefficients. These observations can be qualitatively explained via the difference between TNT-surface and TNT-TNT interactions mediated by water molecules. C1 Oak Ridge Natl Lab, Oak Ridge, TN 37831 USA.

In this work, near-edge X-ray absorption fine structure measurements verify that well-ordered monolayers can be formed using acetic acid in the solvent. Disordered monolayers with unbound molecules present in the film result using only ethanol. A stark reorientation occurs upon deprotonation of the end group by rinsing in a KOH solution. This reorientation of the end group is reversible with tilted-over, hydrogen-bound carboxyl groups while the carboxylate ion end groups are upright. C(1s) photoemission shows that SAMs formed and rinsed with acetic acid in ethanol have protonated end groups, while SAMs formed without acetic acid have a large fraction of carboxylate-terminated molecules.

A polycation [PEI = poly(ethylenimine)] was deposited from a dilute solution, while a polyanion (PAZO = poly[1- [4-(3-carboxy-4-hydroxyphenylazo) benzenesulfonamido]-1,2-ethanediyl, sodium salt]) was deposited from a mixture containing a fixed concentration of polyanion and various concentrations of the anionic surfactant sodium dodecyl sulfate (SDS). Coadsorption of SDS and PAZO onto PEI layers was observed using both deposition methods and attributed to strong PEI-SDS interactions and entropic factors. Increasing the concentration of SDS resulted in films containing progressively less adsorbed PAZO. No further reduction in the amount of adsorbed PAZO was observed above the SDS critical micelle concentration. We attribute the film growth behavior to a fast adsorption of SDS onto PEI, followed by a slower adsorption of PAZO onto the remaining unoccupied binding sites. We observe that SDS interpenetrates throughout the PAZO and PEI layers, increasing the surface hydrophobicity of both. We observed similar behavior for both ionically self-assembled and spin-assembled systems. C1 New Coll Florida, Div Nat Sci, Sarasota, FL 34243 USA.

In this system, adsorption is due to the interaction between chelated divalent copper or nickel ions and the histidine moieties at the outer surface of the protein. The binding interaction of histidine with the Ni-IDA complex is known to be much weaker than that with Cu-IDA. Adsorption was examined under conditions of constant surface area with an initial pressure of 40 mN/m. After similar to12 h little further change in reflectivity was detected, although the surface pressure continued to slowly increase. For chelated Cu2+ ions, the adsorbed layer structure in the final state was examined for bulk myoglobin concentrations of 0.10 and 10 muM. For the case of 10 muM, the final layer thickness was similar to43 Angstrom. This corresponds well to the two thicker dimensions of myoglobin in the native state (44 Angstrom x 44 Angstrom x 25 Angstrom) and so is consistent with an end-on orientation for this disk-shaped protein at high packing density. However, the final average volume fraction of amino acid segments in the layer was 0.55, which is substantially greater than the value of 0.44 calculated for a completed monolayer from the crystal structure. This suggests an alternative interpretation based on denaturation. GIXD was used to follow the effect of protein binding on the crystalline packing of the lipids and to check for crystallinity within the layer of adsorbed myoglobin. Despite the strong adsorption of myoglobin, very little change was observed in the structure of the DSIDA film. There was no direct evidence in the XR or GIXD for peptide insertion into the lipid tail region. Also, no evidence for in-plane crystallinity within the adsorbed layer of myoglobin was observed. For 0.1 muM bulk myoglobin concentration, the average segment volume fraction was only 0.13 and the layer thickness was less than or equal to25 Angstrom. Adsorption of myoglobin to DSIDA-loaded with Ni2+ was examined at bulk concentrations of 10 and 50 muM. At 10 muM myoglobin, the adsorbed amount was comparable to that obtained for adsorption to Cu2+- loaded DSIDA monolayers at 0.1 muM. But interestingly, the adsorbed layer thickness was 38 Angstrom, substantially greater than that obtained at low coverage with Cu-IDA. This indicates that either there are different preferred orientations for isolated myoglobin molecules adsorbed to Cu-IDA and Ni-IDA monolayer films or else myoglobin denatures to a different extent in the two cases. Either interpretation can be explained by the very different binding energies for individual interactions in the two cases. At 50 muM myoglobin, the thickness and segement volume fraction in the adsorbed layer for Ni-IDA were comparable to the values obtained with Cu-IDA at 10 muM myoglobin.

The calculations for the bulk agree with the densities, bond distances, bond angles, and lattice enthalpies reported in the literature. The calculated energies also correlate with measured dissolution rates: the lattice energies show a log-linear relationship to the macroscopic dissolution rates at circumneutral pH. Moreover, the energies of ion pairs translated along surface steps are calculated and found to predict experimentally observed microscopic step retreat velocities. Finally, pit formation excess energies decrease with increasing pit size, which is consistent with the nonlinear dissolution kinetics hypothesized for the initial stages of pit formation.

After 19 passages, a variant virus, CCcon. 19, had increased sensitivity to both sCD4 and NAb b12 that binds to a CD4-binding site (CD4BS)-associated epitope, but decreased sensitivity to anti-CD4 antibodies. CCcon. 19 retains the R5 phenotype, its resistance to other NAbs was unaltered, its sensitivity to various entry inhibitors was unchanged, and its ability to replicate in macrophages was modestly increased. We define CCcon. 19 as a primary T-cell adapted (PTCA) variant. Genetic sequence analysis combined with mutagenesis studies on clonal, chimeric viruses derived from CC1/85 and the PTCA variant showed that the most important changes were in the V1/V2 loop structure, one of them involving the loss of an N-linked glycosylation site. Monomeric gp120 proteins expressed from CC1/85 and the PTCA variant did not differ in their affinities for sCD4, suggesting that the structural consequences of the sequence changes were manifested at the level of the native, trimeric Env complex. Overall, the adaptation process probably involves selection for variants with higher CD4 affinity and hence greater fusion efficiency, but this also involves the loss of some resistance to neutralization by agents directed at or near to the CD4BS. The loss of neutralization resistance is of no relevance under in vitro conditions, but NAbs would presumably be a counter-selection pressure against such adaptive changes in vivo, at least when the humoral immune response is intact.

In dilute Si1-xGex islands we observe an extended shape evolution involving a new "barn" shape formed by introduction of steep {111} facets not observed at higher mismatch strain. This extended shape evolution implies a delayed onset of plastic deformation as a result of an altered competition between strain relaxation via coherent islands and the introduction of dislocations in this regime.

Within experimental error, the deformation behavior is found to be independent of the deuterium content and different for (001) and (100) surfaces. Multiple discontinuities (so-called "pop-in" events) in force-displacement curves are observed during indentation, loading, but not during unloading. Slip is identified as the major mode of plastic deformation in DKDP, and pop-in events are attributed to the initiation of slip. (C) 2004 American Institute of Physics.

The experimental data obtained at different frequencies of the ac field (8 and 16 GHz) from differently processed films (as deposited and oxygen annealed) strongly suggest the occurrence of a crossover in the dominant loss mechanism. The crossover is driven by the do bias field: at weak fields the loss is governed by an extrinsic mechanism(s) whereas, at higher fields, the contribution of an intrinsic mechanism (dc field-induced quasi-Debye loss) becomes predominant.

It would then be possible to obtain two electron-hole pairs from, one. In bulk materials, this process is inherently inefficient due to the constraint of simultaneous energy and momentum conservation. We calculated the rate of these processes, and of selected competing ones, in CdSe colloidal dots, using our semi-empirical nonlocal pseudopotential approach. We find much higher carrier multiplication rates than in conventional bulk materials for electron excess energies just above the energy gap E-g. We also find that in a neutral dot, the only effective competing mechanism is Auger cooling, whose decay rates can be comparable to those calculated for the carrier multiplication process.

A two-layered porous cathode design has been developed that includes a thinner layer with smaller grain diameters at the cathode/electrolyte interface followed by a relatively thicker outer layer with larger grains at the electrode/oxidant interface. Results are presented for the determination of spatially dependent current generation distributions, assessment of the importance of concentration polarization, and sensitivity to measurable microstructural variables. Estimates of the electrode performance in air at 700 degreesC indicate that performance approaching 3.1 A/cm(2) at 0.078 V is theoretically possible. The limitations of the model are described, along with efforts needed to verify and refine the predictions. The feasibility of fabricating the electrode configuration is also discussed.
