A 5-km-long source line and a 3-km-long receiver line were located on top of Yucca Mountain ridge and inside the Exploratory Study Facility (ESF) tunnel, respectively. Numerical modeling showed that the first arrival P waves are mainly propagated in the repository horizon at depth. Therefore two-dimensional travel time inversions were performed after the actual source locations on the ridge were projected onto the layer of interest at depth. Static corrections were applied to absorb the scatter in the new source locations and to correct for variations in source and receiver coupling and travel time shifts. Zero-offset amplitude variations of the first arrivals across the receiver line inside the tunnel showed strong correlation with the fracture density determined by measurements along the tunnel wall. Wave guidance by subhorizontal fractures is suggested as a possible source for this phenomenon. Tomographic inversion of the travel time data revealed a low-velocity zone in the south central area of the repository horizon. Conversion of the velocity tomography results to fracture-density tomograms showed good correlation with fracture intensity mapped along tunnel walls. The fractured zone extends over a large area in the southern region of the potential repository, in particular, southwest of the intensely fractured zone encountered in the ESF tunnel. The rock in the northern section of the repository appears more competent compared to the highly fractured areas in the south.

The three-dimensional geometry of 12 bedding-parallel stylolites in several limestones was measured using laser and mechanical profilometers, and statistical characteristics of the surfaces were calculated. All the stylolites analyzed turn out to have self-affine fractal roughness with a well-characterized crossover length scale separating two self-affine regimes. Strikingly, this characteristic length scale falls within a very narrow range for all the stylolites studied, regardless of the microstructure sizes. To explain the data, we propose a continuous phenomenological model that accounts for the development of the measured roughness from an initially flat surface. The model postulates that the complex interface morphology is the result of competition between the long-range elastic redistribution of local stress fluctuations, which roughen the surface, and surface tension forces along the interface, which smooth it. The model accounts for the geometrical variability of stylolite surfaces and predicts the dependence of the crossover length scale on the mechanical properties of the rock.

Events from a range of back azimuths minimize the effects of multipathing. The resulting velocity model reveals a transition in lithospheric thickness from 200 km in the Great Plains to 45 - 55 km beneath the Rio Grande Rift, thickening beneath the Colorado Plateau to 120 - 150 km. The upper mantle low-velocity signature of the rift is roughly twice the width of its surface morphology. An asthenospheric low-velocity channel underlies the region west of the Great Plains and extends to 300 km depth. This channel is likely the result of warm mantle infill behind the sinking Farallon plate. Buoyant forces within this channel are sufficient to support much of the high elevation of the rift and plateau. No evidence for a deep mantle source is found beneath the rift, implying that present rifting is not driven by deep mantle upwelling. Velocities from 55 to 90 km beneath the rift axis are 10% slower than beneath the Great Plains, consistent with small amounts of partial melt. Low velocities extend to 200 - 300 km depth on either side of the rift but not directly beneath it, forming an inverted-U shape. This feature may reflect mantle that has cooled through vertical advection in a subadiabatic environment. Upwelling may be reinforced by small-scale convection caused by variations in lithospheric thickness and shallow mantle temperatures. C1 New Mexico State Univ, Dept Phys, Las Cruces, NM 88003 USA.

We describe the first kinetic study of the purified and reconstituted ZitB by stopped-flow measurements of transmembrane fluxes of metal ions using a metal-sensitive fluorescent indicator encapsulated in proteoliposomes. Metal ion filling experiments showed that the initial rate of Zn2+ influx was a linear function of the molar ratio of ZitB to lipid and was related to the concentration of Zn2+ or Cd2+ by a hyperbola with a Michaelis-Menten constant (K-m) of 104.9 +/- 5.4 muM and 90.1 +/- 3.7 muM, respectively. Depletion of proton stalled Cd2+ transport down its diffusion gradient, whereas tetraethylammonium ion substitution for K+ did not affect Cd2+ transport, indicating that Cd2+ transport is coupled to H+ rather than to K+. H+ transport was inferred by the H+ dependence of Cd2+ transport, showing a hyperbolic relationship with a K-m of 19.9 nM for H+. Applying H+ diffusion gradients across the membrane caused Cd2+ fluxes both into and out of proteoliposomes against the imposed H+ gradients. Likewise, applying outwardly oriented membrane electrical potential resulted in Cd2+ efflux, demonstrating the electrogenic effect of ZitB transport. Taken together, these results indicate that ZitB is an antiporter catalyzing the obligatory exchange of Zn2+ or Cd2+ for H+. The exchange stoichiometry of metal ion for proton is likely to be 1: 1.

emission in p(p)over-bar collisions at root s=1.8 TeV using the missing energy signature SO PHYSICAL REVIEW LETTERS LA English DT Article ID PHYSICS EVENT GENERATION; ALPHA-S CALCULATION; QUANTUM-THEORY; DIMENSIONS; ORDER; HIERARCHIES AB We report on a search for direct Kaluza-Klein graviton production in a data sample of 84 pb(-1) of p (p) over bar collisions at roots=1.8 TeV, recorded by the Collider Detector at Fermilab. We investigate the final state of large missing transverse energy and one or two high energy jets. We compare the data with the predictions from a (3+1+n)-dimensional Kaluza-Klein scenario in which gravity becomes strong at the TeV scale. At 95% confidence level (C.L.) for n=2, 4, and 6 we exclude an effective Planck scale below 1.0, 0.77, and 0.71 TeV, respectively. C1 Univ Florida, Gainesville, FL 32611 USA.

TI Search for lepton-flavor violation in the decay tau(-)-> l(-)l(+)l- SO PHYSICAL REVIEW LETTERS LA English DT Article ID TAU-DECAYS; LIMIT; MASS AB A search for the lepton-flavor-violating decay of the tau into three charged leptons has been performed using 91.5 fb(-1) of data collected at an e(+)e(-)center-of-mass energy around 10.58 GeV with the BABAR detector at the SLAC storage ring PEP-II. In all six decay modes considered, the numbers of events found in data are compatible with the background expectations. Upper limits on the branching fractions are set in the range (1-3)x10(-7) at 90% confidence level. C1 Lab Annecy Le Vieux Phys Particules, F-74941 Annecy Le Vieux, France.

These islands appear with current profile modification leading to magnetic fluctuation reduction in the Madison symmetric torus RFP. Magnetic island widths decrease to an unprecedented level, reducing the overlap of adjacent islands and allowing distinct islands to appear. The structures are observed in multichord measurements of soft-x-ray emissivity. The soft-x-ray data is validated with Poincare reconstructions of the magnetic field structure in the core.

Femtosecond coincidence imaging of CF3I photodynamics illustrates how competing multiphoton dissociation pathways can be distinguished, which would be impossible using photoelectron or ion imaging alone. Ion-electron energy correlations and photoelectron angular distributions reveal competing processes for the channel producing (e(-)+CF3++I). The molecular-frame photoelectron angular distributions of the two major pathways are strikingly different. C1 Free Univ Amsterdam, Ctr Laser, NL-1081 HV Amsterdam, Netherlands.

Here we show, for eight heterosexual transmission pairs, that recipient viruses were monophyletic, encoding compact, glycan-restricted envelope glycoproteins. These viruses were also uniquely sensitive to neutralization by antibody from the transmitting partner. Thus, the exposure of neutralizing epitopes, which are lost in chronic infection because of immune escape, appears to be favored in the newly infected host. This reveals characteristics of the envelope glycoprotein that influence HIV-1 transmission and may have implications for vaccine design. C1 Univ Alabama, Dept Microbiol, Birmingham, AL 35294 USA.

The expression can be used to predict the critical radius from the cloud liquid water content and the droplet number concentration, eliminating the need to prescribe the critical radius as an empirical constant in numerical models. Data from stratiform clouds are analyzed, indicating that on average continental clouds have larger critical radii than maritime clouds. This work further suggests that anthropogenic aerosols affect the autoconversion process by increasing the critical radius and decreasing the characteristic radius, which in turn inhibits the initiation of embryonic raindrops, and by decreasing the autoconversion rate after the initiation process. The potential impact of this work on the evaluation of the second indirect aerosol effect is discussed. C1 Brookhaven Natl Lab, Div Atmospher Sci, Upton, NY 11973 USA.

PhIP was found to comprise similar to70% of US mean dietary intake of total HAs, with pan-frying and chicken being the single cooking method and meat type contributing the greatest to total estimated HA exposures. This analysis demonstrated significantly higher concentrations in grilled/barbecued meats than in other cooked meats. African-American males were estimated to consume nearly twofold and similar to35 to 40% more PhIP (and total HAs) than white males at ages < 16 and >30 years, respectively. (C) 2004 Elsevier B.V.

Our method uses LC/MS/MS to detect four metabolites and four deuterated internal standard peaks in a single chromatographic run. N-2-OH-PhIP-N-2-glucuronide was the most abundant urinary metabolite excreted by the 12 individuals who participated in our study. N-2-PhIP glucuronide was the second most abundant metabolite for 8 of the 12 volunteers. The stability of PhIP metabolism over time was studied in three of the volunteers who repeated the assay eight times over a 2.5 year-period. PhIP metabolite excretion varied in each subject over time, although the rate of excretion was more constant. Our results suggest that quantifying PhIP metabolites should make future studies of individual susceptibility and dietary interventions possible. (C) 2003 Elsevier B.V. All rights reserved.

The same ionic NOx species (NO+, NO+ -NO2, NO3-, formed by the disproportionation of NO2, were observed to form on both materials under dry conditions at room temperature. The thermal stabilities of these species, however, were vastly different on the two materials. Room-temperature evacuation was sufficient to decompose the NO+NO2 adduct in Na-Y, while this species was stable up to 350K over Ba-Y The adsorbed NO+ was also much more stable over Ba-Y than on Na-Y. Water significantly affected the adsorbed NO, species on both materials. In the presence of water, the IR signatures of adsorbed NO+ were eliminated from both catalysts; however, it did not affect the IR feature of the NO+NO2 species on Ba-Y. In the TPD spectra, the NO2 desorption peak shifted from 350 K to 520 K on Na-Y preexposed to water. In Ba-Y, the high-temperature NO2 desorption feature of similar to470 K shifted to similar to620 K as a result of adsorption on the water-containing sample, while the low-temperature peak remained unchanged.

It was found that SWNTs are naturally protein-affinitive in an aqueous ferritin solution, resulting in significant ferritin-SWNT conjugation and the solubilization of the nanotubes. The conjugation is further enhanced and stabilized in the presence of a coupling agent for amidation to promote the formation of covalent linkages. The natural protein-affinity of SWNTs may be alleviated or even eliminated by the functionalization of the nanotubes with hydrophilic polymers or better with oligomeric poly(ethylene glycol) moieties.

We take advantage of the discrete size distribution to correlate the peaks in a histogram of nanocrystal heights with the distinct abundance peaks in a mass spectrum. The correlation establishes a mapping from STM height to core mass or mean core diameter. This is vitally important for the interpretation of size-dependent "single-molecule" tunneling spectra from nanocrystal compounds. C1 Georgia Inst Technol, Sch Chem, Atlanta, GA 30332 USA.

Measurements were taken at cryogenic and room temperatures, in the dark as well as in the light-induced charge-separated state P+Q(A)Q(B)(-). Evidence for protein matrix expansion near the Fe2+ site because of lowering the temperature from 290 to 15 K was observed as elongation of Fe2+ to neighboring atom distances. Upon formation of the charge-separated state P(+)Q(A)Q(B)(-), the distances between the Fe2+ and neighboring atoms were reduced slightly. Replacing the native Fe2+ with either Mn2+ or Zn2+ resulted in distinct differences in local structural responses to both temperature and charge separation, suggesting that the conformation changes caused by these factors may follow different paths in the potential energy landscape of the protein. The XAFS measurements of Fe2+ site structure revealed a more symmetrically oriented imidazole ligands arrangement around Fe than those in current crystal structures. These measurements for high-precision Fe site local structure indicate that XAFS is a useful technique for probing structural changes in the metal site environment because of temperature change, metal replacement, and light-induced charge separation in the reaction center proteins.

We report here the results of an extensive experimental survey and characterization of over 20 species of transition-metal compounds for their activity in the Hill reaction at the lipid-water interface of Photosystem II (PSII) membrane fragments. Four new PSII Hill reagents were identified: PtCl4, [PtCl6](2-), [OsCl6](2-), and [RuCl6](2-). Each can be photosynthetically reduced by PSII. The negative charge of the metal compound species is apparently essential for their interaction with the reducing site of PSII When PtCl4 is dissolved in water, it combines with water molecules to form H-2[PtCl4(OH)(2)], which can dissociate to the negatively charged species [PtCl4(OH)(2)](2-) at neutral pH. These findings could have significant implications for photosynthesis, nanoscale science, and nanofabrication in the field of biometallocatalysis.

This paper explores microstructure development, coating characterization and properties of HVOF sprayed alumina coatings and compares these with those produced using the conventional air plasma spray process. We report on the characterization of these coatings using small-angle neutron scattering (SANS) and X-ray computed microtomography (XMT) to explain the behavior observed for the two coating systems. Microstructure information on porosity, void orientation distribution, void mean opening dimensions and internal surface areas have been obtained using SANS. XMT (X-ray synchrotron microtomography) has been used to nondestructively image the microstructural features in 3D at a 2.7-mum spatial resolution over a 2-3 turn field of view. 3D medial axis analysis has been used for the quantitative analysis of the coarse void space in order to obtain information on the porosity, specific surface area, pore connectivity and size distribution of the larger voids in the coatings. The results reveal different pore morphologies for the two spray processes. While only globular pores are imaged in the plasma sprayed coatings due to the spatial resolution limit, highly layered porosity is imaged in the HVOF coating. When the quantitative SANS and XMT information are combined, the different thermal and mechanical properties of the two different coating types can be explained in terms of their distinctly different void microstructures.

In particular, colossal magnetoresistance(7) in these materials - the dramatic reduction of resistivity in a magnetic field - is closely related to the observed texture owing to nanometre- and micrometre-scale inhomogeneities(1) (-6,8). Despite accumulated data from various high-resolution probes, a theoretical understanding for the existence of such inhomogeneities has been lacking. Mechanisms invoked so far, usually based on electronic mechanisms and chemical disorder(9-11), have been inadequate to describe the multiscale, multiphase coexistence within a unified picture. Moreover, lattice distortions and long-range strains(12,13) are known to be important in the manganites(14). Here we show that the texturing can be due to the intrinsic complexity of a system with strong coupling between the electronic and elastic degrees of freedom. This leads to local energetically favourable configurations and provides a natural mechanism for the self-organized inhomogeneities over both nanometre and micrometre scales. The framework provides a physical understanding of various experimental results and a basis for engineering nanoscale patterns of metallic and insulating phases.

The gamma-decay of the isomer exposes the rotational band based on the 160-day 23/2(-) isomer, Lu-177m, with band properties which support its proposed configuration. A 90-ns isomer at 1325 keV is associated with the predicted 3-quasiparticle K-pi = 25/2(+) state while a 5-quasiparticle 33/2(+), 902-ns isomer with highly-hindered decays is identified at 2771 keV. Both exhibit rotational bands whose properties are used to support the assigned configurations. The possibility that the K-pi = 39/2- isomer found in this work should be identified with a beta-decaying isomer, proposed recently to populate the 51-min 37/2(-) isomer in Hf-177, is discussed in terms of the implied log f t values, configuration changes, and hindrances for K-forbidden gamma-decays.

Effects of mixing height on aerosol properties SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article DE aerosol; vertical profile; boundary layer ID CENTRAL NEW-MEXICO; BOUNDARY-LAYER; VERTICAL-DISTRIBUTION; AIRBORNE MEASUREMENTS; OPTICAL-PROPERTIES; SIZE DISTRIBUTION; INVERSION; TEMPERATURE; ENERGY; GAS AB The goal of this study was to determine under what meteorological conditions, if any, measurements of aerosol properties made at the Earth's surface are representative of aerosol properties measured within the column of air above the surface. Specifically, this study uses instrumentation from the Atmospheric Radiation Measurement (ARM) Program's Southern Great Plains (SGP) site to determine how the observed mixing height (MH) and the degree of mixing affects the vertical variation of aerosol extensive and intensive properties. The MH was estimated by applying the Heffter [1980] technique with a critical lapse rate of 0.001 K m(-1) to the available radiosonde data. This estimate was then used to determine whether each vertical aerosol profile flight leg from 59 flights was within or above the atmospheric boundary layer (ABL). Although the aerosol extensive properties, such as light absorption by particles sigma(ap), light scattering by particles sigma(sp), and total extinction by particles sigma(ext) measured within the ABL were highly correlated with the surface measurements (R-2=0.74, 0.88, and 0.88, respectively), the airborne measurements of sigma(ap) were systematically lower (slope=0.77). By contrast, the sigma(sp) and sigma(ext) regression line slopes were 0.99 and 1.00. The aerosol extensive properties measured above the ABL were poorly correlated with surface values and were almost an order of magnitude lower than the simultaneous measurements made within the ABL. Aerosol intensive properties such as the single-scattering albedo pi(o), the hemispheric backscatter fraction b, and the Angstrom exponent (a) over circle exhibited a similar behavior (R-2=0.74, 0.61, and 0.55, respectively) but had regression line slopes within the ABL of 0.88, 0.75, and 0.62, respectively. There were no statistically significant correlations between the intensive aerosol properties measured above the ABL and those measured at the surface. Limiting the analysis to well-mixed days with near-neutral static stability did not significantly improve the results. Thus the hypothesis that the best agreement between surface measurements and those within the ABL will occur when the atmosphere is well mixed was not supported by this data set.

Neutron spin echo (NSE) proves that above T similar or equal to 15 K the spin dynamics are governed by a thermally activated single-ion process. At lower temperatures (T < 15 K) this cannot account for the spin dynamics found in ac-susceptibility measurements. It is inferred that a second, slower process, with a different thermal signature dominates. We suggest that this is a quantum-mechanical tunnelling process between different spin states separated by a large energy barrier. C1 Oak Ridge Natl Lab, SNS Project, Oak Ridge, TN 37830 USA.

Here we present data on the magnetic nature, especially the spin dynamics of Tb(2)Ti(2)O(7), Gd(2)Ti(2)O(7) and Y(2)Mo(2)O(7). In these systems the ground states are found to be very different. Y(2)Mo(2)O(7) freezes completely into a spin glass-like state, Tb(2)Ti(2)O(7) is a cooperative paramagnetic and remains dynamic down to 15 mK and Gd(2)Ti(2)O(7) enters a unique partially ordered state at similar to1 K.

Oxygen intake is accompanied by a small increase of the unit cell, and a complex superstructure attributed to oxygen ordering appears. Average structure refinements show the presence of additional oxygen close to the centres of Cu triangles, and an average copper valence of +2. The two compounds appear to be isostructural. Magnetic measurements show a non-linear thermal increase of the inverse magnetic susceptibility up to some maximum, soon followed by a minimum around 280 K.

They are Os(II)dinitrogen (e.g., trans-, cis-, or fac-[Os-II-N-2]), Os(II)-nitrosyl [Os-II-NO](+) (e.g., trans- or cis-[Os-II-NO](+)), Os(IV)-hydroxyhydrazido (e.g., cis-[Os-IV-N(H)N(Me)(OH)](+)), and Os(IV)-methoxyhydrazido (e.g., trans-/ cis-[Os-IV-N(H)N(H)(OMe)](+), and trans-/ cis-[Os-IV-N(H)N(Me)(OMe)](+)) adducts. The products depend in a subtle way on the electron content of the starting nitrido complexes, the nature of the hydroxylamines, the nature of the methoxylamines, and the reaction conditions. Their appearance can be rationalized by invoking the formation of a series of related Os(IV) adducts which are stable or decompose to give the final products by two different pathways. The first involves internal 2-electron transfer and extrusion of H2O, MeOH, or WOW to give [Os-II-N-2]. The second which gives [Os-II-NO](+) appears to involve seven-coordinate Os(IV) intermediates based on the results of an N-15-labeling study.

The isolation and structural characterization of trans-and cis-isomers of complexes 4 and 5 (4a and 4b, 5a and 5b, respectively) are also reported. Studies of the thermal decompositions of the complexes (by thermogravimetric analysis and solution H-1 NMR spectroscopy) were performed. Xerogels with approximate compositions of 2MoO(1.5)(.)2P(2)O(5) and 2MoO(1.5)(.)2P(2)O(5)(.)2SiO(2) were derived from 4a and 5a or 5b, respectively, via solution thermolyses (toluene). The as-synthesized (and dried) xerogels contain one equiv of HNMe2 per molybdenum center (by combustion analysis, IR spectroscopy, and thermogravimetric analysis), and these materials have high surface areas (up to 270 m(2) g(-1)). Upon calcination at 300 degreesC, the coordinated amines are lost and the surface areas are significantly reduced (to 40 m(2) g(-1) and <5 m(2) g(-1) for the materials derived from 4 and 5a or 5b, respectively). Solid-state P-31 MAS NMR spectroscopy suggests that the as-synthesized xerogels retain structural features of the starting molecular precursors, as indicated by the presence of resonances that correspond to both bridging and terminal -O2P((OBu)-Bu-t)(2) ligands. Upon calcination at 300 degreesC, the resonances for bridging -O2P((OBu)-Bu-t)(2) groups are replaced by those for PO43- . The material derived from 4 exhibits low activity and poor selectivity for the oxidative dehydrogenation (ODH) of propane to propylene. Cothermolyses of 4 and Bi[OSi((OBu)-Bu-t)(3)](3) resulted in formation of Bi/Mo/P/Si/O materials with improved performance for the ODH of propane.

Our results show that without making compressibility approximations the ballooning modes are unstable for the entire plasma sheet where the equatorial beta(eq)greater than or equal to1, and the most unstable modes are located in the strong cross-tail current sheet region in the near-Earth plasma sheet, which maps to the initial brightening location of the breakup arc in the ionosphere. However, the MHD beta(eq) threshold is too low in comparison with observations by AMPTE/CCE, which show that prior to substorm onset a low frequency instability is excited only when beta(eq)>50. The difficulty can be mitigated by including kinetic effects, which greatly increase the stabilizing effects of field line tension and can enhance the beta(eq) threshold to limit the unstable region to the cross-tail current sheet region.

The highest ambient temperature conductivity of 3.5 x 10(-7) S cm(-1) was obtained for a polyacrylate ether-based single ion conductor containing eight EO units in the side chain and five EO units in the cross-linking side chain, to which the anion was fixed with a salt concentration of EO/Li = 20. For polyacrylate ether-based single ion conductors, an increase of chain length in both side chains and cross-linking anion chains favors an increase of ionic conductivity. The addition of 50 wt % EC/DMC (1/1, wt/wt) increased the ionic conductivity by more than 2 orders of magnitude due to both the increase in ionic mobility from the liquid phase and the increase in the concentration of free ions from the high dielectric constant of the solvent. The preliminary Li/Li cycling profiles of dry polyacrylate- and polymethacrylate ether-based single ion conductors are encouraging as almost no concentration polarization or relaxation was observed. The observed increase in cell potential with cycling is apparently due to an increase in the interfacial impedance associated with the SEI layer, and the cell failure is accompanied by the decomposition of the ester bond of the polyacrylate backbone.

Molybdenum content was varied from 1 to 4 wt%, and the highest mobility achieved was 83 cm(2) V-1 s(-1) at a carrier concentration of 3.0x10(20) cm(-3) without any postdeposition treatment for one of the films made from the target with 2 wt% Mo. Temperature-dependent Hall analysis indicated that this high mobility is limited by phonon scattering, whereas the method of four coefficients analysis showed that the conduction band is parabolic.

Using this technique, preferential transport channels across a p(+)-ZnTe/p-CdTe back contact of a p-CdTe/n-CdS solar cell are imaged with 20 nm spatial resolution. Transport across this contact is highly nonuniform. Large areas of high resistance coexist with nanoscale low-resistance regions that are strongly correlated with grain boundaries in the CdTe absorber. These results suggest an important role of grain boundaries as near-contact conducting channels. (C) 2004 American Institute of Physics. C1 Colorado Sch Mines, Dept Phys, Golden, CO 80401 USA.

We identify three angular regimes in which pinning is dominated by different types of correlated and uncorrelated defects. Those regimes are present in all cases, but their extension and characteristics are sample dependent, reflecting differences in texture and defect density. The more defective nature of the films on IBAD turns into an advantage as it results in higher J(c), demonstrating that the performance of the films on single crystals is not an upper limit for the IBAD coated conductors.

It takes advantage of differences in the vibrational frequencies of adatom-substrate bonds at terraces and steps. With a properly tuned infrared laser, one can selectively excite only the adatom-substrate bonds at steps and enhance the mobility of these adatoms, consequently promoting step-flow growth and reducing film roughness. The feasibility of this method is shown theoretically with respect to the prototype system of chemical vapor deposition growth of silicon. (C) 2004 American Institute of Physics.

The need for new capabilities to visualize and compare cross-species alignment data is intensified by the growing number of genomic sequence datasets being generated for an ever-increasing number of organisms. To be efficient these visualization algorithms must support the ability to accommodate consistently a wide range of evolutionary distances in a comparison framework based upon phylogenetic relationships. Results: We have developed Phylo-VISTA, an interactive tool for analyzing multiple alignments by visualizing a similarity measure for multiple DNA sequences. The complexity of visual presentation is effectively organized using a framework based upon interspecies phylogenetic relationships. The phylogenetic organization supports rapid, user-guided interspecies comparison. To aid in navigation through large sequence datasets, Phylo-VISTA leverages concepts from VISTA that provide a user with the ability to select and view data at varying resolutions. The combination of multiresolution data visualization and analysis, combined with the phylogenetic framework for interspecies comparison, produces a highly flexible and powerful tool for visual data analysis of multiple sequence alignments.

This salt, which crystallizes in the monoclinic space group P2(1)/c with a = 17.2324(6) Angstrom, b = 13.2740(5) Angstrom, c = 10.9467(4) Angstrom, beta = 96.974(2)degrees, and V = 2485.5(2) Angstrom(3), forms a layered structure. One layer contains dimerized BEDT-TTF electron donor molecules and isolated [Ni(tdas)(2)](-) monoanions, while the second layer contains chains of [Ni(tdas)(2)](-) monoanions. Conductivity measurements show that (BEDT-TTF)[Ni(tdas)(2)] has a semiconductor-to-semiconductor transition near 200 K, while magnetic measurements indicate that it is an S = 1/2 paramagnet with weak antiferromagnetic coupling. Reflectance spectra reveal bands in the near-infrared region (6.6 x 10(3) and 10.6 x 10(3) cm(-1)) which are typical of (BEDT-TTF)(2)(2+) dimers. From these data, we can conclude that the unpaired electron lies on the [Ni(tdas)(2)](-) anions. Tight-binding band structure calculations were used to analyze the electronic structure of this salt.

It is shown that the double groups can be represented in terms of wreath products and powerful matrix cycle type generators that are used to construct their character tables. It is shown that these tables are of use when spin-orbit coupling is included in the Hamiltonian even for molecules containing lighter atoms. Applications to nonrigid molecules such as Tl2H4/Tl2H4+ are considered. It is shown that the tunneling splittings and the nuclear spin statistical weights can be obtained for such species using the character tables thus constructed. The spinor double groups of several other molecules such as hexamethyl dilead and heavy weakly bound clusters such as (PoH2)(4) are also considered. (C) 2004 American Institute of Physics.

The new formulation employs a separation of radial and angular terms with a simple index structure that leads to computational efficiency and ease of physical interpretation. For the case of the Coulomb interaction, we compare the present formulation with two conventional multipole expansions: the Cartesian tensor and the irreducible spherical tensor expansions. The new formalism leads to efficient numerical algorithms that are useful for general applications beyond intermolecular potentials. In addition to the electrostatic Coulomb interaction, we illustrate the formalism with applications to special function theory and a bipolar expansion involved in potential theory.

Both density functional and quantum Monte Carlo calculations indicate that the electronic energy gap of the liquid vanishes at about ninefold compression and 3000 K. At these conditions the computed conductivity values are characteristic of a poor metal. These findings are consistent with those of recent shock wave experiments but the computed conductivity is larger than the measured value. From our ab initio results we conclude that the transition is driven by molecular dissociation rather than disorder and that both temperature and pressure play a key role in determining structural changes in the fluid.

For the growth of these TPV-structurcs the new version of liquid-phase electroepitaxy has been employed. First type of structure consists of the n-InAs (111)B substrate and compositionally graded p-InAsP layer with the increasing concentration of phosphorus from impurity levels up to 6%, along the growth direction. The second type of structure consists of p-InAsPSb layer directly grown on a n-InAs (100) substrate. These structures have a uniform thickness, a mirror-like surface and a very flat interface. The dislocation density on the surface layer was no more than N-D = 10(5) cm(-2). The I-V and C-V characteristics of n-InAs/p-InAsP and n-InAs/p-InAsPSb TPV structures have been investigated. The spectral response of these diode structures has been measured. The results of these studies show that the second type of TPV structures has better performance than the first type.

X-ray diffraction (XRD) revealed that the as-sputtered films are of mainly (112)oriented CuInS2 incorporating a minor Culn, phase. XRD rocking curve of CuInS2 (112) showed a full width at half maximum of 0.1degrees, indicating an epitaxial-like growth of (112)-CuInS2 films on (0001)-sapphire. Six peaks dominantly show up in the XRD phi-20 map, between which there are additional regular modulations present, suggesting a multi-domain structure of the thick double-layered films. Furthermore, the morphology and internal microstructure of the quasi-epitaxially sputtered CuInS2 films were characterized by scanning electron microscopy and transmission electron microscopy, respectively.

A stabilized record efficiency of 9.47% has independently been confirmed by NREL for an amorphous silicon single-junction p-i-n cell (similar to 1 cm(2)) deposited on LP-CVD ZnO coated glass. Micromorph tandem cells with an initial efficiency of 12.3% show after light-soaking a stable performance of 10.8%. The monolithic series connection by laser-scribing for module fabrication has been developed at IMT as well, for both amorphous single-junction and micromorph tandem cells in combination with the LP-CVD ZnO technique. Mini-modules (areas between 22 and 24 cm(2)) with an aperture efficiency of 8.7% in the case of amorphous single-junction p-i-n cells (independently confirmed by NREL), and of 9.8% in the case of micromorph tandem cells, have been obtained.

The lowest energy structure is one in which B-N bonding is present as boron and nitrogen occupy each of the 12 pentagons of the fullerene cage. The cluster is polar with a net dipole moment of 0.55 D, which indicates an enhanced tendency toward reactivity with other media. The excitation spectrum shows that the lowest transition of 1.75 eV is dipole-allowed. The optical gap Of C-48(BN)(6) is redshifted by 1.17 eV relative to that Of C-60, suggesting possible use as single-molecule fluorescent probes for various applications. (C) 2004 Elsevier B.V.

This has involved measurement of the Hugoniot in terms of stress, shock velocity and particle velocity, and measurements of the lateral stress, which have been used to determine the shear strength, and its variation with shock stress. Analysis of the relationship between shock velocity and particle velocity shows a simple linear response, in common with many other materials. Shear strength has also been shown to increase with shock stress, with a break in slope at ca 1.0 GPa. Below this stress, the material appears to behave in a simple elastic manner, which suggests a Hugoniot elastic limit of 1 GPa. Shear strength has also been observed to increase significantly behind the shock front both above and below 1 GPa. This behaviour has been observed in other polymeric materials, where it was suggested that these materials were responding by a viscoplastic mechanism.

Complex structure, highly permeable C matrices are described for coating with optimum thicknesses of any type of refractory target material (metal, carbide or oxide). Prescriptions are given for the design and fabrication of custom-engineered targets with diffusion lengths compatible with the release of isotopes of interest within their lifetimes. Computationally derived thermal analysis information is presented for selected low-density, fibrous, highly permeable targets, subjected to direct irradiation with I GeV, 100-400 kW proton beams. From these studies, internal thermal radiation is reconfirmed as an important heat transfer (cooling) mechanism within low-density, fibrous and composite targets. By utilization of the radiation cooling effect and beam manipulation techniques, in combination with placement of additional heat shielding on the exit end of targets, beam power depositional densities can be controlled and temperatures homogenized to acceptable levels within fast diffusion release, fast effusive-flow ISOL targets subjected to irradiation with 400 kW proton beams, as required at next-generation radioactive ion beam facilities, (C) 2004 Elsevier B.V.

A simple, fast, inexpensive and close to universal method, based on suspension of finely divided target material in a binder to form a paint, has been developed that can be vacuum infiltrated to uniformly coat the surfaces of highly permeable fibrous target matrices with compound target materials and thus, form fast diffusion-release, mechanically and thermally stable production targets for ISOL-based radioactive ion beam research applications. In this report, the paint infiltration technique is described and the universal character of the technique illustrated by preparing several nitride, carbide, oxide and sulfide targets for potential use at the Holifield Radioactive Ion Beam Facility or at future high energy ISOL-based research facilities such as the Rare Isotope Accelerator facility, now under proposal for construction in the USA.

These radioactive ion beams are then accelerated to energies of a few MeV per nucleon and delivered to experimental stations for use in nuclear physics and nuclear astrophysics experiments. At the heart of this facility is the RIB production target, where the radioactive nuclei are produced using beams of light ions (p, d, He-3, alpha) to induce nuclear reactions in the target nuclei. Several target materials have been developed and used successfully, including Al2O3, HfO2, SiC, CeS, liquid Ge, liquid Ni, and a low-density matrix of uranium carbide. The details of these targets and some of the target developments that led to the delivery of high-quality radioactive ion beams are discussed in this paper. (C) 2003 Elsevier B.V.

High level electronic structure calculations are used to characterize the,potential energy surfaces, and these results are not adjusted to obtain good agreement with experiment in the subsequent kinetic analysis. An approximate two-dimensional master equation is used to determine phenomenological rate coefficients, k(T,p). The effects of angular momentum conservation, tunneling, and the use of variational transition-state theory (as opposed to conventional transition-state theory) to compute microcanonical rate coefficients are investigated in detail. For both reactions, the low-pressure limit is approached very slowly, because reaction just above threshold must occur strictly by tunneling. Assuming a single-exponential-down model for P(E,E'), we deduce from experiment values of , the average energy transferred in a deactivating collision, as a function of temperature for both C2H3 and C2H5 in baths of He, Ar, and N-2. Our results support the idea that (DeltaE(d)) increases roughly linearly with temperature, at least for weak colliders. The agreement between theory and experiment is remarkably good for both reactions. Values of k(T,p) for the two reactions are given in the Troe format for use in modeling.

Both genetic changes provided, within a uniform genetic background, a test of the "source-sink" hypothesis that down-regulation of photosynthesis in elevated carbon dioxide is a result of inability to form sufficient "sinks" for the additional photosynthate. Plants were grown under ambient and elevated [CO2] (550 mumol mol(-1)) in the field, using free air gas concentration enrichment (FACE). Mutation of the determinate cultivar, Elf, to an indeterminate form did not result in increased responsiveness to elevated [CO2]. This may reflect a large sink capacity in the selection of determinate cultivars. In elevated [CO2] only the determinate isoline of the indeterminate cultivar (Williams-dtl) and the non-nodulating genotype showed down-regulation of photosynthesis. This resulted from decreases in apparent in vivo Rubisco activity (V-c.max) and maximum rate of electron transport Increase in total non-structural carbohydrate (TNC) content, which is often correlated with down-regulation of photosynthesis, in Williams-dtl was 80% greater in elevated [CO2] than in ambient [CO2] controls, compared to 40% in the indeterminate line. The results from mutations of the Williams line are consistent with the hypothesis that genetic capacity for the utilization of photosynthate is critical to the ability of plants to sustain increased photosynthesis when grown at elevated [CO2] (C) 2003 Elsevier B.V.

The films were deposited by using magnetron sputtering and characterized by both x-ray and ELTV reflectometry. We find that the new Si/SiC multilayer offers the greatest spectral selectivity at the longer wavelengths, as well as the greatest thermal stability. We also describe the optimization of multilayers designed for the Solar-B EIS instrument. Finally, we compare experimental reflectance data with calculations and conclude that currently available optical constants cannot be used to adequately model the performance of many of these multilayers.

The standard picture is that shocks generated by the jet propagate through an inhomogeneous medium and trigger the collapse of overdense clouds, which then become active star-forming regions. In this contribution, we report on recent hydrodynamic simulations of radiative shock-cloud interactions using two different cooling models: an equilibrium cooling-curve model assuming solar metallicities and a nonequilibrium chemistry model appropriate for primordial gas clouds. We consider a range of initial cloud densities and shock speeds in order to quantify the role of cooling in the evolution. Our results indicate that for moderate cloud densities (greater than or similar to1 cm(-3)) and shock Mach numbers (less than or similar to20), cooling processes can be highly efficient and result in more than 50% of the initial cloud mass cooling to below 100 K. We also use our results to estimate the final H-2 mass fraction for the simulations that use the nonequilibrium chemistry package. This is an important measurement, since H-2 is the dominant coolant for a primordial gas cloud. We find peak H-2 mass fractions of greater than or similar to10(-2) and total H-2 mass fractions of greater than or similar to10(-5) for the cloud gas, consistent with cosmological simulations of first star formation. Finally, we compare our results with the observations of jet-induced star formation in "Minkowski's Object," a small irregular starburst system associated with a radio jet in the nearby cluster of galaxies Abell 194. We conclude that its morphology, star formation rate (similar to0.3 M-circle dot yr(-1)) and stellar mass (similar to1.2 x 10(7) M-circle dot) can be explained by the interaction of a similar to9 x 10(4) km s(-1) jet with an ensemble of moderately dense (similar to10 cm(-3)), warm (10(4) K) intergalactic clouds in the vicinity of its associated radio galaxy at the center of the galaxy cluster.

These "clumpy'' flows are relevant to a wide variety of astrophysical environments, including the evolution of molecular clouds, outflows from young stars, planetary nebulae, and active galactic nuclei. The experiment consists of a strong shock (driven by a pulsed-power machine or a high-intensity laser) impinging on a region of randomly placed plastic rods. We discuss the goals of the specific design and how they are met by specific choices of target components. An adaptive mesh refinement hydrodynamic code is used to analyze the design and establish a predictive baseline for the experiments. The simulations confirm the effectiveness of the design in terms of articulating the differences between shocks propagating through smooth and clumpy environments. In particular, we find significant differences between the shock propagation speeds in a clumpy medium and those in a smooth one with the same average density. The simulation results are of general interest for foams in both inertial confinement fusion and laboratory astrophysics studies. Our results highlight the danger of using average properties of inhomogeneous astrophysical environments when comparing timescales for critical processes, such as shock crossing and gravitational collapse.

The large effective area and similar to 100 GeV energy threshold of Milagro allow it to detect VHE gamma-ray burst (GRB) emission with much higher sensitivity than previous instruments and a fluence sensitivity at VHE energies comparable to that of dedicated GRB satellites at keV - MeV energies. Even in the absence of a positive detection, VHE observations can place important constraints on GRB progenitor and emission models. We present limits on the VHE flux of 40 s-3 hr duration transients near Earth as well as sensitivity distributions that have been corrected for gamma-ray absorption by extragalactic background light and cosmological effects. The sensitivity distributions suggest that the typical intrinsic VHE fluence of GRBs is similar to or weaker than the keV - MeV emission, and we demonstrate how these sensitivity distributions may be used to place observational constraints on the absolute VHE luminosity of GRBs for any GRB emission and progenitor model.

Here we show that nearly 1 year after the explosion the supernova has become fainter overall, but the Ha emission has brightened and broadened dramatically compared to earlier observations. We have obtained spectropolarimetry data that show that the hydrogen-rich matter is highly aspherically distributed. These observations suggest that the supernova exploded inside a dense, clumpy, disklike circumstellar environment. C1 Univ Calif Berkeley, Lawrence Berkeley Lab, Berkeley, CA 94712 USA.

Here we consider the simulation of such structures with a Modified form of Invasion Percolation (MIP). Results show that slender pathways form in fracture networks for a wide range of expected conditions, can be maintained when subsequent matrix imbibition is imposed, and may arise even in the context of primarily matrix flow due to the action of fractures as barriers to inter-matrix block transport.

Selected experimental highlights from the early RHIC program are presented. Measurements of the total multiplicity in heavy-ion collisions show a surprising similarity to measurements in e(+)e(-) collisions after nuclear geometry is taken into account. RHIC has sufficient center-of-mass energy to use large transverse momentum particles and jets as a probe of the nuclear medium. Signatures of "jet quenching" due to radiative gluon energy loss of fast partons in a dense medium are observed for the first time at RHIC. In order to account for this energy loss, initial energy densities of 30-100 times normal nuclear matter density are required. C1 Univ Calif Berkeley, Lawrence Berkeley Lab, Berkeley, CA 94720 USA.

We use a two-dimensional generalization of Darcy's law that accounts for shear thinning of a non-Newtonian fluid. In the limit of weak shear thinning, the pressure is found from a ladder of two linear,elliptic boundary value problems, each to be solved in the whole fluid domain. A moving body fitted grid is used to resolve the flow near the interface, while most of the fluid domain is covered with a fixed Cartesian grid. Our use of body-conforming grids reduces grid anisotropy effects and allows the accurate modeling of boundary conditions. (C) 2003 Elsevier Inc. All rights reserved.

The self-adjoint semi-implicit operator and variational approach to spatial discretization are synergistic and enable simulation in the extremely stiff conditions found in high temperature plasmas without sacrificing the geometric flexibility needed for modeling laboratory experiments. Growth rates for resistive tearing modes with experimentally relevant Lundquist number are computed accurately with time-steps that are large with respect to the global Alfven time and moderate spatial resolution when the finite elements have basis functions of polynomial degree (p) two or larger. An error diffusion method controls the generation of magnetic divergence error. Convergence studies show that this approach is effective for continuous basis functions with p greater than or equal to 2, where the number of test functions for the divergence control terms is less than the number of degrees of freedom in the expansion for vector fields. Anisotropic thermal conduction at realistic ratios of parallel to perpindicular conductivity (chi(\\)/chi(perpendicular to)) is computed accurately with p greater than or equal to 3 without mesh alignment. A simulation of tearing -mode evolution for a shaped toroidal tokamak equilibrium demonstrates the effectiveness of the algorithm in nonlinear conditions, and its results are used to verify the accuracy of the numerical anisotropic thermal conduction in 3D magnetic topologies.

RNR catalyzes the rate-limiting step of de novo dNTP synthesis. Sml1 is a downstream effector of the Mec1/Rad53 cell cycle checkpoint pathway. The phosphorylation by Dun1 kinase during S phase or in response to DNA damage leads to diminished levels of Sml1. Removal of Sml1 increases the population of active RNR, which raises cellular dNTP levels. In this study using mass spectrometry and site-directed mutagenesis, we have identified the region of Sml1 phosphorylation to be between residues 52 and 64 containing the sequence GSSAS-ASASSLEM. This is the first identification of a phosphorylation sequence of a Dun1 biological substrate. This sequence is quite different from the consensus Dun1 phosphorylation sequence reported previously from peptide library studies. The specific phosphoserines were identified to be Ser(56), Ser(58), and Ser(60) by chemical modification of these residues to S-ethylcysteines followed by collision activated dissociation. To investigate further Sml1 phosphorylation, we constructed the single mutants S56A, S58A, S60A, and the triple mutant S56A/S58A/S60A and compared their degrees of phosphorylation with that of wild type Sml1. We observed a 90% decrease in the relative phosphorylation of S60A compared with that of wild type, a 25% decrease in S58A, and little or no decrease in the S56A mutant. There was no observed phosphate incorporation in the triple mutant, suggesting that Ser(56), Ser(58), and Ser(60) in Sml1 are the sites of phosphorylation. Further mutagenesis studies reveal that Dun1 kinase requires an acidic residue at the +3 position, and there is cooperativity between the phosphorylation sites. These results show that Dun1 has a unique phosphorylation motif. C1 Oak Ridge Natl Lab, Div Chem Sci, Organ & Biol Mass Spectrometry Grp, Oak Ridge, TN 37831 USA.

The models were derived from travel times of compressional and shear seismic phases recorded by the La Ristra passive seismic array deployed from July 1999 to May 2001. Large variations in seismic velocity (up to 8% in S and 5% in P) are seen across the transect in the upper 200 km of the mantle. Seismically slow mantle underlies the Rio Grande rift and Jemez lineament and relatively slow mantle is seen beneath the Navajo volcanic field within the Colorado Plateau. The relative variations of P and S velocity imply that high temperatures are the primary cause of the slow mantle although a small amount of partial melting or hydration cannot be ruled out. Sharp boundaries in mantle seismic velocity are coincident with boundaries of Proterozoic structural trends implying that ancient lithospheric structure exerts a control on the tectonic and magmatic activity in the region. Weaker seismic variations are imaged below 200 km depth with three southeastward dipping structures in our images. Two of the structures have fast seismic anomalies, beneath the central Colorado Plateau and the Great Plains respectively, and the third has anomalously slow seismic wave speed. We interpret the western deep seismic anomaly to be foundering Farallon slab and the slow anomaly just to the east as upwelling mantle possibly associated with volatile release from the sinking Farallon slab. Beneath the Great Plains, there is also downwelling in the upper mantle. The combination of upwelling in the west and downwelling in the east are likely part of an upper mantle convection cell that may include entrained lithosphere from beneath the rift.

Relativistic Heary Ion Collider (RHIC). Chemical and kinetic equilibrium model fits to our data reveal strong radial flow and long duration from chemical to kinetic freeze-out in central Au+Au collisions. The chemical freeze-out temperature appears to be independent of initial conditions at RHIC energies. C1 Univ Birmingham, Birmingham, W Midlands, England. Argonne Natl Lab, Argonne, IL 60439 USA.

Collaboration TI Search for the radiative decays B ->rho gamma and B-0 ->omega gamma SO PHYSICAL REVIEW LETTERS LA English DT Article ID TO-LEADING ORDER; B-MESONS; SUPERSYMMETRY; GAMMA; QCD AB A search of the exclusive radiative decays B-->rho(770)gamma and B-0-->omega(782)gamma is performed on a sample of about 84x10(6) B (B) over bar events collected by the BABAR detector at the SLAC PEP-II asymmetric-energy e(+)e(-) storage ring. No significant signal is seen in any of the channels. We set upper limits on the branching fractions B of B(B-0-->rho(0)gamma)<1.2x10(-6), B(B+-->rho(+)gamma)<2.1x10(-6), and B(B-0-->omegagamma)<1.0x10(-6) at 90% confidence level (C.L.). Using the assumption that Gamma(B-->rhogamma)=Gamma(B+-->rho(+)gamma)=2xGamma(B-0-->rho(0)gamma), we find the combined limit B(B-->rhogamma)<1.9x10(-6), corresponding to B(B-->rhogamma)/B(B-->K(*)gamma)<0.047 at 90% C.L.

The rings originate from the spatial separation of p and n carriers, and occur at the interface of the p and n domains, where excitons are generated. We explore the states of excitons in the ring over a range of temperatures down to 380 mK and report a transition of the ring into a periodic array of aggregates, a new low-temperature ordered exciton state.

The predominance of low frequency modes in the noise profile allows for decoherence scenarios where relatively slow control rates suffice for a drastic improvement. However, the actual figure of merit is very sensitive to the details of the dynamics, with decoupling performance which may deteriorate for non-Gaussian noise and/or high frequency working points.

Down to the lowest temperatures, both compounds remain cubic and reveal strong magnetic frustration. Specifically the Fe compound is characterized by a Curie-Weiss (CW) temperature Theta(CW)=-45 K and does not show any indications of order down to 50 mK. In addition, the Jahn-Teller ion Fe2+ is orbitally frustrated. Hence, FeSc2S4 belongs to the rare class of spin-orbital liquids. MnSc2S4 is a spin liquid for temperatures T>T(N)approximate to2 K.

We report on theoretical and experimental studies of a related phenomenon concerning light emitted from photonic crystal waveguides that are less than a wavelength wide. We find that the termination of the photonic crystal end facets and an appropriate choice of the wavelength are instrumental in achieving very low numerical apertures. Our results hold promise for the combination of photonic crystal waveguides with conventional optical systems such as fibers, waveguides, and freely propagating light beams.

Despite the large 7% mismatch, the second layer of Ag from the Ru exhibits a hexagonal structure with Ag bulk spacing, providing a close match to bulk Ag. The first layer of Ag (next to Ru) is reconstructed in a highly symmetrical and regular structure containing monolayer long threading dislocations. We argue that this structure may generally occur to relieve strain in a certain class of heterophase interfaces. C1 Sandia Natl Labs, Livermore, CA 94550 USA.

At 400 eV, vacancies and mono- and di-interstitials form, but often annihilate within milliseconds. At 2 and 5 keV, larger clusters can form and persist. While vacancies are immobile, interstitials aggregate into clusters (I-n) with surprising properties; e.g., an I-4 is immobile, but an impinging I-2 can create a metastable I-6 that diffuses on the nanosecond time scale but is stable for years.

It has enhanced stability and low power consumption because it works as a switching regulator. The rectangular power pulses supplied to the filament produce small rectangular voltage pulses which are observed by a separate pair of wires connected to the filament ends. These pulses are amplified and converted to the saw-like signal by a low-pass filter. The saw-like signal is connected to the inverting input of the Schmitt trigger, whereas the noninverting input is connected to a reference voltage supplied either from a potentiometer or generated by a computer. The regulator is used in our laboratory for precision potassium analysis by the isotope dilution method. The obtained reproducibility of potassium determination in terms of relative standard uncertainty is 0.5%. (C) 2004 Elsevier Ltd. All rights reserved.

The extent of promotional effect on catalysis due to indium doping depends both on the speciation of hydrocarbon used as a reducing agent in addition to reaction temperature. In/gamma-alumina catalysts were tested with eight hydrocarbons (propane, propene, methanol, ethanol, 1-propanol, 2-propanol, acetaldehyde, isooctane) at a C-1:N ratio of 12 to investigate the effect of hydrocarbon structure and chemistry on activity for plasma-enhanced catalysis. The functionality, the location of the functional group, as well as the molecular size all proved to have an impact on the ability of the hydrocarbon to participate in NOx reduction chemistry. Plasma assist provided benefits at moderate temperature, but NOx reduction was dominated by thermal activity (no plasma required) at high temperature. The effect of aging on catalyst performance was also examined, and the most negative impact on thermal activity was observed at moderate temperatures. Plasma assist resulted in recovery of nearly all activity for most of the oxygenated hydrocarbons examined. At high temperature, aging had negligible impact on catalyst performance with the exception of catalytic reduction with methanol. (C) 2003 Elsevier B.V. All rights reserved.

The calculated results show that a new, tetrahedrally coordinated fluoride anion hydration structure F-(H2O)(4) cluster is lower in Gibbs free energy than the previously considered most stable structure of F-(H2O)(4). The first ab initio prediction of potential stable hydration structures for F-(H2O)(n) clusters (n = 8, 12, and 16) are given. The energetic results show that the tetrahedrally coordinated fluoride anion hydration structure becomes more stable as compared to the other hydration structures with a pyramidal coordination, i.e., a surface ion cluster state, as the cluster size increases from n = 8 to n = 12 to n = 16. This suggests that, with increasing n, the fluoride anion will be internally solvated in large enough F-(H2O)(n) clusters. These results provide insight into the transition from the hydration structure found in small gas-phase hydrated-anion clusters to the hydration structure observed in aqueous solution. The calculated results show that, for a given n, the bulk solvent effects can qualitatively change the relative thermodynamic stability of different possible isomers of F-(H2O)(n) clusters and the most stable structure in solution is not necessarily the most stable structure in the gas phase. When n = 16, a pyramidally coordinated fluoride anion hydration structure is the most stable structure in the gas phase, whereas a tetrahedrally coordinated fluoride anion hydration structure has the lowest free energy in solution. The absolute hydration free energy of fluoride anion in aqueous solution, DeltaG(hyd)(298)(F-), is predicted to be -104.3 +/- 0.7 kcal/mol by using a reliable computational protocol of first-principles solvation-included electronic structure calculations. The predicted DeltaG(hyd)(298)(F-) value of -104.3 0.7 kcal/mol, together with our previously calculated AGhyd 298 (HI) value of -262.4 kcal/mol determined by using the same computational protocol, gives DeltaG(hyd)(298)(H+) + DeltaG(hyd)(298)(H+) = -366.7 +/- 0.7 kcal/mol in excellent agreement with the value of -366.5 kcal/mol derived from the available experimental data.

The calculations use supercells that contain up to 326 atoms. The crystal structures calculated for the (H2O)(6)/host and the (H2O)(8)/host systems are in qualitative agreement with those obtained from X-ray diffraction studies. The calculations confirm the presence of (H2O)(8) clusters with C-i symmetry in the (H2O)(8)/host crystal and verify the existence of one-dimensional chains of fused water hexamers within channels of the (H2O)(6)/host crystal. The major differences observed between the calculated and experimental structures are attributed to the limitations of the Perdew-Wang functional for describing long-range dispersion interactions.

Deprotonation occurs at or below 300 K to form trimethyl acetate, (CH3)(3)CCOO-, and hydroxide, OH-. (CH3)(3)CCOO- is bound to exposed Ti4+ cations, and OH- involves a bridging oxygen atom of the substrate. On the basis of temperature-programmed desorption and isothermal reaction mass spectrometry, the desorbing products include (CH3)(3)CCOOH, isobutene (i-C4H8), carbon monoxide, and water accompanied by smaller amounts of other products including methyl isopropenyl ketone (CH2=C(CH3)C(=O)CH3) isobutane (i-C4H10), and di-tert-butyl ketone, (CH3)(3)CC(=O)C(CH3)(3). Much of the (CH3)(3)CCOO- is relatively stable and decomposes to release mainly carbon monoxide and isobutene above 550 K with a maximum rate at 660 K. Thermal desorption to 750 K leaves a carbon-free surface that is indistinguishable from the initially clean surface. During dosing at 550 K, a steady-state reaction condition is realized with about half the adsorption sites being occupied at any instant.

It has been found that the eta(1)-HCO species attached to a Ru atom by a single Ru-C bond is unstable, and that it will convert to more strongly bound eta(1)- and eta(3)-HCO surface species. These more highly coordinated species decompose readily to produce H(a) and CO(a) via low activation energy reactions, indicating that the observation of HCO(a) species in any bonding mode at temperatures above 90 K is unlikely. Additionally, we found that abstraction of H from HCO(a) upon atomic H bombardment is another low-barrier reaction mechanism leading to the formation of adsorbed CO and desorption of an H-2 molecule. Using a stepped Ru(109) surface, containing atomic steps periodically located every 22 A along the Ru(001) surface, we have bombarded chemisorbed CO with atomic H at T < 170 K in an attempt to produce and spectroscopically observe adsorbed HCO species by infrared reflection absorption spectroscopy. These experiments have been unsuccessful, and instead we have observed the surface crowding of CO(a) by H(a) species, and the displacement of CO(a) at high H(a) coverages. Both the experimental and theoretical results support the conclusion that the formyl species can be easily dissociated on the Ru surface. These studies throw into question previous measurements indicating that the interaction of atomic hydrogen with CO is effective in producing stable adsorbed formyl species on Ru.

A series of molecules including CH4, CH3Cl, CH2O2, CHCl3, and CCl4 are used as probes to test the chemical reactivity of the FeO(111) surface. The temperature-programmed desorption spectra show no evidence of dissociative adsorption or chemical reaction between the substrate and the adsorbates. The desorption kinetics studies reveal that all the molecules are physisorbed and have desorption kinetics with an order between 0 and 1. Kinetic analysis is conducted, assuming both zero- and first-order desorption, and shows that an uncertainty in the desorption order introduces an error in determination of the terrace site desorption energies (theta = 0.5 ML) of only similar to2%. The desorption energies for the series of molecules increase with the number of chlorine atoms in the molecule. The increase of desorption energies is not linear with the molecular polarizability, and the deviations from linearity are attributed to the permanent dipole in some of the molecules. We conclude that the oxygen-terminated Feo(111) surface is in general unreactive toward both C-H and C-Cl bonds in methane and its chlorinated derivatives.

LETTERS B LA English DT Article ID HADRONIC Z(0) DECAYS; ZEUS BARREL CALORIMETER; TRACKING DETECTOR; REAR CALORIMETER; P-INTERACTIONS; BREIT FRAME; LOW Q(2); HERA; INTERFEROMETRY; MULTIPLICITY AB Bose-Einstein correlations in one and two dimensions have been studied in deep inelastic ep scattering events measured with the ZEUS detector at HERA using an integrated luminosity of 121 pb(-1). The correlations are independent of the virtuality of the exchanged photon, Q(2), in the range 0.1 < Q(2) < 8000 GeV2. There is no significant difference between the correlations in the current and target regions of the Breit frame for Q(2) > 100 GeV2. The two-dimensional shape of the particle-production source was investigated, and a significant difference between the transverse and the longitudinal dimensions of the source is observed. This difference also shows no Q(2) dependence. The results demonstrate that Bose-Einstein interference, and hence the size of the particle-production source, is insensitive to the hard subprocess.

We demonstrate that this is not true, by exhibiting a simple counterexample. We employ the formalism of homeotic fermions, in a simple model where CPT conjugate fermions have different masses. This model can be supersymmetrized to a hypermultiplet of fields which form a representation of the conventional N = 2 SUSY algebra. Nevertheless, CPT conjugate states in this hypermultiplet have different masses. These surprising results do not violate either the CPT theorem or the Haag-Lopuszanski-Sohnius theorem.

The charge is coupled to the lattice distortions and therefore temperature induced fluctuations and coherent base-pair openings ("bubbles") directly affect the charge's motion. The influence of the charge-lattice coupling constant on polaronic behavior, as well as the effect of different initial charge configuration are described. We also briefly present preliminary results from numerical simulations suggesting the existence of a temperature window with long time coherent polaronic transport. This transport mechanism may be either polaronic hopping or polaron drifting depending on the value of the coupling constant. (C) 2003 Elsevier B.V. All rights reserved.

The current paper is intended to report the velocity results derived from this experiment to seismically constrain the area around the resurgent dome. We report the results of velocity logs, V-p/V-s ratios, and VpVs products for the depth interval from 880-1980 m. The Bishop tuff can be divided into three zones (top-to-bottom) of intermediate velocities (V-p approximate to 4.0 km/s, V-s approximate to 2.3 km/s), followed by higher velocities (V-p = 4.7 km/s, V-s = 2.9 km/s) in the lower-central part, and a decrease back to the lower values at the bottom of the sequence. The analysis of VpVs data suggested a decrease in porosity in the lower-central section of the tuff as a possible explanation, which was supported by direct density measurements from a nearby location.

Visible-UV spectroscopy demonstrated that Ctr1c bound four Cu(I) ions, structurally identified as a Cu-4(1)(mu-S-CYS)(6) Cluster by Xray absorption spectroscopy. This was the only metalated form detected by electrospray ionization mass spectrometry. An average dissociation constant K-D = (K1K2K3K4)(1/4) = 10(-19) for binding of Cu(I) to Ctr1c was estimated via competition with the ligand bathocuproine disulfonate bcs (beta(2) = 10(19.8)). Equivalent experiments for the yeast chaperone Atx1 and an N-terminal domain of the yeast Golgi pump Ccc2, which both bind a single Cu(I) ion, provided similar K-D values. The estimates of KD were supported by independent estimates of the equilibrium constants Kex for exchange of Cu(I) between pairs of these three proteins. It is apparent that, in vitro, the three proteins buffer "free" Cu(I) concentrations in a narrow range around 10(-9) M. The results provide quantitative support for the proposals that, in yeast, (a) "free" copper concentrations are very low in the cytosol and (b) the Cu(I) trafficking gradient is shallow along the putative Ctrlc - Atx1 - Ccc2n metabolic pathway. In addition, both Ctr1c and its copper-responsive transcription factor Mac1 contain similar clusters which may be important in signaling copper status in yeast.

While earlier proposals considered N2S2 to be aromatic, recent electronic structure calculations claimed that N2S2 is a singlet diradical. Our careful reexamination does not support this assertion. N2S2 is closed shell and aromatic since it satisfies all three generally accepted criteria for aromaticity: energetic (stability), structural (planarity with equal bond lengths), and magnetic (negative nucleus-independent chemical shift due to the T electrons). These characteristics as well as the electronic structure of N2S2 are compared with those for an isoelectronic pi system, Li2C4H4, motivated by theoretical and recent experimental investigations that confirmed its aromaticity. However, N2S2 and Li2C4H4 are both essentially 2pi-electron aromatic systems with a formal N-S (C-C) bond order of 1.25 even though they both have 6pi electrons. This is because four of the six pi electrons occupy the nonbonding pi HOMOs and only two electrons participate effectively in the aromatic stabilization. However, wave function analysis shows relatively large LUMO occupation numbers; this antiboncling effect can be said to reduce the aromatic character by approximately 7% and 4% for N2S2 and Li2C4H4, respectively.

These data are used to further evaluate the applicability of these nuclides for direct radiometric dating of polar ice. In order to minimize artifacts during sample processing we developed an improved method utilizing ethylenediaminetetraacetic acid (EDTA) to stabilize uranium-series nuclides dissolved in polar ice during ice melting and filtration. Our measurements revealed low uranium-series daughter abundances and large uranium-series (U-234/U-238, Th-230/U-234, Ra-226/Th-230, Pa-231/U-235) disequilibria in the filtered <0.05-mum fraction of these ice samples. Both the long-lived uranium-series disequilibria and Be-10/Cl-36 ratios are most likely recently inherited from precipitation. The short-lived daughter Ra-226 is the exception and is enhanced in the <0.05-mum fraction, presumably due to recoil effects from dust bands present in the ice. Based on a simplified recoil model, ice ages of approximately 30 ka are obtained from our data. Absence of measurable U-238-U-234-Th-230-Ra-226 disequilibria in the volcanic dust bands also suggests that ice ages are greater than 10 ka, consistent with recoil-based ages. Our relatively young ice ages can be compared with previously published relatively old terrestrial ages of meteorites from this area and suggests that meteorites at Allan Hills have experienced a multi-stage history of ice accumulation and/or ice flow. Our results also suggest that large uranium-series disequilibria can be inherited from precipitation, which may provide a method for dating clear ice samples. (C) 2004 Elsevier B.V.

Measurements indicate a decrease in the activated aerosol fraction (F-N) for particle diameters d(P) > 100 nm with cloud temperature from F-N similar to 0.54 in summer liquid-phase clouds to F-N similar to 0.08 in winter mixed-phase clouds. The latter may be attributed to the Bergeron-Findeisen mechanism whereby ice crystals grow at the expense of liquid water drops, releasing formerly activated aerosols back into the interstitial phase. This provides a means to distinguish the indirect effects of aerosols on drops and ice crystals. C1 Univ Copenhagen, Dept Chem, Chem Lab 5, DK-2100 Copenhagen O, Denmark.

Here, we describe a rapid method to measure structural similarity based on the profiles of representative local features of C. distance matrices of compared protein structures. We first extract a finite number of representative local feature (LF) patterns from the distance matrices of all protein fold families by medoid analysis. Then, each C. distance matrix of a protein structure is encoded by labeling all its submatrices by the index of the nearest representative LF patterns. Finally, the structure is represented by the frequency distribution of these indices, which we call the LF frequency (LFF) profile of the protein. The LFF profile allows one to calculate structural similarity scores among a large number of protein structures quickly, and also to construct and update the "map" of the protein structure universe easily. The LFF profile method efficiently maps complex protein structures into a common Euclidean space without prior assignment of secondary structure information or structural alignment.

Live and dead Escherichia coli were concentrated and selectively released by applying stepped DC voltages across a microchannel containing an array of insulating posts etched in glass. The only electrodes present were two platinum wires placed in the inlet and outlet reservoirs, producing mean electric fields of up to 200 V/mm across the insulators. The cells were labeled with Syto 9 and propidium iodide and imaged through a fluorescent microscope. Cell trapping and release were controlled by modifying the relative responses of electrokinesis and DEP by adjusting the magnitude of the applied voltage. Dead cells were observed to have significantly lower dielectrophoretic mobility than live cells, whereas the electrokinetic mobilities of five and dead cells were indistinguishable. The locations of the bands of differentially, trapped cells were consistent with predictions. In addition, cells were selectively trapped and concentrated against backgrounds of 1- and 0.2-mum carboxylate-modified polystyrene particles. This first application of iDEP for simultaneous live/dead bacteria separation and concentration illustrates its potential as a front-end method for bacterial analysis.

In spite of very different morphology and crystallinity, the optical properties and chemical composition of the two types of microstructures are very similar. The structures formed with femtosecond (fs) pulses are covered with a disordered nanocrystalline surface layer less than 1 mum thick, while those formed with nanosecond (ns) pulses have very little disorder. Both ns-laser-formed and fs-laser-formed structures absorb near-infrared (1.1-2.5 mum) radiation strongly and have roughly 0.5% sulfur impurities. (C) 2004 American Institute of Physics.

In this regime, the strain profile displays several local maxima above the embedded island. The regions with local strain maxima serve as nucleation centers for growth of surface islands under appropriate growth conditions, resulting in locally well-organized surface islands above the embedded island. Our theoretical results are in excellent agreement with recent experiments for Ge islands embedded in Si. (C) 2004 American Institute of Physics.

The RD spectra for the crystals arise not only from the surface anisotropy but also from the bulk anisotropy due to the monoclinic structure of the bulk crystal.

Using atomistic empirical pseudopotential simulations, we find that the band alignment between random and ordered domains changes from type I to type II at xsimilar or equal to0.4. This leads to an increase by two to three orders of magnitude in the radiative lifetime of the electron-hole recombination. This can explain the experimentally observed mobility-lifetime product behaviors with changing Al concentration. The type I to type II transition results from a competition between the ordering-induced band folding effect and hole confinement on Ga-rich monolayers within the ordered structure.

Samples are fabricated by a liquid phase deposition, and their thermal conductivities are measured by a differential 3omega method. Nanoporous Bi thin films exhibit an order-of-magnitude reduction in thermal conductivity compared to that of solid films, most likely the result of a reduction in phonon mean free path. When porous Bi films are exposed to a hydrogen plasma, thermal conductivity measurements reveal no variation with extent of porosity, while electrical conductivity is much more sensitive to porosity, suggesting the possibility of independent control of these two intrinsic properties.

The material quality of InN improved significantly for the layer thickness larger than 150 nm. The highest extracted value of the room temperature electron mobility was close to 850 cm(2)/V s for samples with electron carrier concentration of similar to4x10(18) cm(-3). The measured dependence of the electron mobility on electron concentration is interpreted using the model accounting for ionized impurity scattering, polar optical scattering, and compensation. The MEMOCVD-grown material exhibited stronger photoluminescence (PL) compared to InN deposited using conventional metalorganic chemical vapor deposition. Room temperature PL spectra were similar to InN grown using molecular beam epitaxy (MBE) with peak emission at 0.8 eV. The obtained results demonstrate the potential of the MEMOCVD technique for deposition of high quality InN epitaxial layers at reduced temperatures comparable to those used in MBE growth.

The present work is an experimental study of 36degreesYX cut LiTaO3 based Love-wave devices for detection of pathogenic spores in aqueous conditions. Given that the detection limit (D-I) of Love-wave-based sensors is a strong function of the overlying waveguide, two waveguide materials have been investigated, which are polyimide and polystyrene. To determine the mass sensitivity of Love-wave sensor, bovine serum albumin (BSA) protein was injected into the Love-wave test cell while recording the magnitude and phase shift across each sensor. Polyimide had the lowest mass detection limit with an estimated value of 1.0-2.0 ng/cm(2), as compared to polystyrene where D-I = 2.0 ng/cm(2). Suitable chemistries were used to orient antibodies on the Love-wave sensor using protein G. The thickness of each biofilm was measured using ellipsometry from which the surface concentrations were calculated. The monoclonal antibody BD8 with a high degree of selectivity for anthrax spores was used to capture the non-pathogenic simulant B. thuringiensis B8 spores. Bacillus subtilis spores were used as a negative control to determine whether significant non-specific binding would occur. Spore aliquots were prepared using an optical counting method, which permitted removal of background particles for consistent sample preparation. This work demonstrates that Love-wave biosensors are promising for low-level detection for whole-cell biological pathogens. (C) 2003 Elsevier B.V. All rights reserved.

These properties are essential for the identification and classification of microorganisms and cells. The complexity of microorganisms in terms of their chemical composition and internal structure make the interpretation of their spectral signature a difficult task. In this paper, a model is proposed for the quantitative interpretation of spectral patterns resulting from transmission measurements of prokaryotic microorganism suspensions. It is also demonstrated that different organisms give rise to spectral differences that may be used for their identification and classification. The proposed interpretation model is based on light scattering theory, spectral deconvolution techniques, and on the approximation of the frequency dependent optical properties of the basic constituents of living organisms. The quantitative deconvolution in terms of the interpretation model yields critical information necessary for the detection and identification of microorganisms, such as size, dry mass, dipicolinic acid concentration, nucleotide concentration, and an average representation of the internal scattering elements of the organisms. E. coli, P. agglomerans, B. subtilis spores, and vegetative cells and spores of Bacillus globigii are used as case studies. It is concluded that spectroscopy techniques coupled with effective interpretation models are applicable to a wide range of cell types found in diverse environments. (C) 2003 Elsevier B.V.

Na-ISA crystallizes in the monoclinic space group P2(1) (#4) with cell parameters a = 9.2267(11)Angstrom, b = 5.0765(6) Angstrom, c = 9.7435(l 1) Angstrom, beta = 103.304(2)degrees, V = 444.13(9) Angstrom(3), Z = 2. The structure was refined by full-matrix least-squares on F-2 yielding final R-values (all data) R1 = 0.0361 and R(w)2 = 0.0935. The structure of Na-ISA consists Of (C6H11O6)(-) anions arranged in layers parallel to the be plane. An extended network of O-H...O hydrogen bonds links the (ISA)(-) anions and the crystal water molecules. Each sodium atom is coordinated by four oxygen atoms belonging to four different (ISA)(-) anions and by one water molecule. The resulting NaO5 polyhedra are linked by sharing common corners in zig-zag chains running parallel to the b-axis. Published by Elsevier Ltd. C1 Sandia Natl Labs, Albuquerque, NM 87185 USA.

The method used throughout this paper is based on the highly efficient Head-Gordon and Pople (HGP) approach of evaluation of electron repulsion integrals (ERI). Thus only straightforward modifications of existing codes that employ HGP or HGP-PRISM scheme are necessary to implement our approach. (C) 2003 Elsevier B.V All rights reserved.

This approach is based on a reduced space Successive Quadratic Programming (rSQP) algorithm, and it allows the reuse of existing PDE-based modeling codes. This approach leads to an efficient simultaneous strategy, where the NLP and the PDE model are solved at the same time. A number of refinements were made to the NLP algorithm to enhance its performance and reliability for large, nonlinear models. This study considers PDE-based optimization problems to demonstrate the effectiveness of this approach. In particular, we apply this approach to MPSalsa, a finite element PDE Solver developed at Sandia National Laboratories, and consider a chemical vapor deposition (CVD) reactor model as the optimization application. Here, our goal is optimize the operating conditions to produce a thin film of gallium nitride with a spatially uniform thickness. To minimize nonuniformity of the film, a novel NLP formulation is described and evaluated based on constraint aggregation. In addition to the design optimization strategy, we incorporate a stability analysis of the optimal design to assure that it is a stable steady state. (C) 2003 Elsevier Ltd. All rights reserved.

They are identical to antitaxial or 'crack-seal' quartz veinlets in terrestrial rocks, and are extraterrestrial and ancient because they pre-date a 4.40 Ga metamorphism. The quartz was likely deposited from liquid water solutions (as are terrestrial veins); other potential solvents or transport mechanisms are inadequate or unlikely. Because there is no indication of internal (magmatic) water in the eucrite meteorites and thus in Vesta, the water from which the veinlet was deposited probably came from outside Vesta. By analogy with water ice deposits on the Moon and Mercury, Vesta and similar asteroids may have had (or now have) polar ice deposits, possibly derived from comet impacts. (C) 2004 Elsevier B.V.

Unannealed trilayers show no oxidation of the bottom magnetic layer for barriers thicker than 1.1 nm. However, upon annealing, we find that the metallic XPS peak of the top layers decrease dramatically, while that of the bottom and barrier layers increases. STM images of the Co top layer on the Al-oxide barrier show that the Co does not agglomerate upon annealing up to 500 degreesC, which suggests interdiffusion is the most likely explanation for the XPS data.

We use a combination of Rutherford backscattering/channeling spectrometry and cross-sectional transmission electron microscopy. Results show that an increase in Al content not only strongly enhances dynamic annealing processes but can also change the main features of the amorphization behavior. In particular, the damage buildup behavior at 300 K is essentially similar for all the AlGaN films studied. Ion-beam-produced disorder at 300 K accumulates preferentially in the crystal bulk region up to a certain saturation level (similar to50%-60% relative disorder). Bombardment at 300 K above a critical fluence results in a rapid increase in damage from the saturation level up to complete disordering, with a buried amorphous layer nucleating in the crystal bulk. However, at 77 K, the saturation effect of lattice disorder in the bulk occurs only for xgreater than or similar to0.1. Based on the analysis of these results for AlGaN and previously reported data for InGaN, we discuss physical mechanisms of the susceptibility of group-III nitrides to ion-beam-induced disordering and to the crystalline-to-amorphous phase transition.

C-60, C59N+, and C48N12: Theory and experiment SO JOURNAL OF CHEMICAL PHYSICS LA English DT Review ID DENSITY-FUNCTIONAL THEORY; FREQUENCY-DEPENDENT POLARIZABILITIES; ELECTRONIC EXCITATIONS; SILICON NANOCRYSTALS; SI NANOCRYSTALS; RESPONSE THEORY; SOLID C-60; HYDROAZAFULLERENE C59HN; AZAFULLERENE C48N12; QUANTUM CONFINEMENT AB Low-energy excitations and optical absorption spectrum of C-60 are computed by using time-dependent (TD) Hartree-Fock, TD-density functional theory (TD-DFT), TD DFT-based tight-binding (TD-DFT-TB), and a semiempirical Zerner intermediate neglect of diatomic differential overlap method. A detailed comparison of experiment and theory for the excitation energies, optical gap, and absorption spectrum of C-60 is presented. It is found that electron correlations and correlation of excitations play important roles in accurately assigning the spectral features of C-60, and that the TD-DFT method with nonhybrid functionals or a local spin density approximation leads to more accurate excitation energies than with hybrid functionals. The level of agreement between theory and experiment for C-60 justifies similar calculations of the excitations and optical absorption spectrum of a monomeric azafullerene cation C59N+, to serve as a spectroscopy reference for the characterization of carborane anion salts. Although it is an isoelectronic analogue to C-60, C59N+ exhibits distinguishing spectral features different from C-60: (1) the first singlet is dipole-allowed and the optical gap is redshifted by 1.44 eV; (2) several weaker absorption maxima occur in the visible region; (3) the transient triplet-triplet absorption at 1.60 eV (775 nm) is much broader and the decay of the triplet state is much faster. The calculated spectra of C59N+ characterize and explain well the measured ultraviolet-visible (UV-vis) and transient absorption spectra of the carborane anion salt [C59N][Ag(CB11H6Cl6)(2)] [Kim et al., J. Am. Chem. Soc. 125, 4024 (2003)]. For the most stable isomer of C48N12, we predict that the first singlet is dipole-allowed, the optical gap is redshifted by 1.22 eV relative to that of C-60, and optical absorption maxima occur at 585, 528, 443, 363, 340, 314, and 303 nm. We point out that the characterization of the UV-vis and transient absorption spectra of C48N12 isomers is helpful in distinguishing the isomer structures required for applications in molecular electronics. For C59N+ and C48N12 as well as C-60, TD-DFT-TB yields reasonable agreement with TD-DFT calculations at a highly reduced cost. Our study suggests that C-60, C59N+, and C48N12, which differ in their optical gaps, have potential applications in polymer science, biology, and medicine as single-molecule fluorescent probes, in photovoltaics as the n-type emitter and/or p-type base of a p-n junction solar cell, and in nanoelectronics as fluorescence-based sensors and switches.

Throughout our calculations, water molecules were maintained at a fixed intramolecular geometry corresponding to the average structure obtained in fully unconstrained simulations. This allows us to use larger time steps than those adopted in ordinary CP simulations of water, and thus to access longer time scales. In the absence of chemical reactions or dissociation effects, these calculations open the way to ab initio simulations of aqueous solutions that require time scales substantially longer than presently feasible (e.g., simulations of hydrophobic solvation). Our results show that structural properties and diffusion coefficients obtained with a rigid model are in better agreement with experiment than those determined with fully flexible simulations. Possible reasons responsible for this improved agreement are discussed. (C) 2004 American Institute of Physics. C1 Graz Univ Technol, Dept Theoret Phys, A-8010 Graz, Austria.

We use local density approximation density functional theory (LDA-DFF) calculations to compute the adsorption energies and vibrational frequencies for CO2 adsorbed on SWNT bundles. The LDA-DFT calculations give a. range of shifts for the asymmetric stretching mode from about -6 to -20 cm(-1) for internally bound CO2, and a range from - 4 to - 16 cm(-1) for externally bound CO2 at low densities. The magnitude of the shift is larger for CO2 adsorbed parallel to the SWNT surface; various perpendicular configurations yield much smaller theoretical shifts. The asymmetric stretching mode for CO2 adsorbed in groove sites and interstitial sites exhibits calculated shifts of -22.2 and -23.8 cm(-1), respectively. The calculations show that vibrational mode softening is due to, three effects: (1) dynamic image charges in the nanotube; (2) the confining effect of the adsorption potential; (3) dynamic dipole coupling with other adsorbate molecules. Infrared measurements indicate that two families of CO2 adsorption sites are present. One family, exhibiting a shift of about - 20 cm(-1) is assigned to internally bound CO2 molecules in a parallel configuration. This type of CO2 is readily displaced by Xe, a test for densely populated adsorbed species, which are expected to be present on the highest adsorption energy sites in the interior of the nanotubes. The second family exhibits a shift of about -7 cm(-1) and the site location and configuration for these species is ambiguous, based on comparison with the theoretical shifts. The population of the internally bound CO2 may be enhanced by established etching procedures that open the entry ports for adsorption, namely, ozone oxidation followed by annealing in vacuum at 873 K. Xenon displacement experiments indicate that internally bound CO2 is preferentially displaced relative to the -7 cm(-1) shifted species. The -7 cm(-1) shifted species is assigned to M adsorbed on the external surface based on results from etching and Xe displacement experiments. (C) 2004 American Institute of Physics.

Here we take the well-known Mo carbides and Ti carbides as an example. Different kinds of structures including the bulk surfaces [Mo2C(001), MoC(001), and TiC(001)] and metcars [Mo8C12 and Ti8C12] are taken into consideration. Systematic studies show that by raising the C coordination number of the metal atoms in the carbides, in general the stability of the carbides increases (metcars are an exception since they include both high-coordinated and low-coordinated metal atoms.); at the same time, the chemical activities of the carbides decrease due to a downshift of the metal d-band center (ligand effect). Considering the better catalysts those that combine high stability and moderate chemical activity, our results suggest that the catalytic potential of Mo carbide systems should decrease in the following sequence: Mo8C12>Mo2C(001) or MoC(001) >pure Mo(110). In spite of having the largest C/Mo ratio, the metcar appears as the most attractive system. Our studies also indicate that the "magic" behavior of metcars is not unique for Mo carbides. Similar behavior is also observed for Ti carbides. This implies that nanoparticles like metcar species could exhibit better performances than the corresponding bulk metal carbides as catalysts.

Doping concentrations of 6 x 10(16)cm(-3) or less (greater than or equal to 0. 3 Omega-cm resistivity) can be achieved in meter-long crystals without exceeding the solubility limit for N. Shorter crystals can be doped more heavily. The time required to transition from undoped (5000 Omega-cm) growth to a 0.2 Omega-cm uniform doping level is about 3 min. This corresponds to less than 1 cm of growth at 0.3cm min(-1). Doping uniformity is within 9% or better axially and 2% radially.

The measured residual stresses, in turn, can be used to monitor evolution of damage in the coatings. Effective use of this technology for real-time damage monitoring requires the identification of trends in measured stresses that can be used as indicators of damage evolution. The present work focuses on studying the evolution of residual stresses in TBC systems during long-term exposure to turbine operating conditions. The coatings are electron beam physical vapor deposited (EBPVD) and atmospheric plasma sprayed (APS) zirconia. The stress evolution in both EBPVD and APS coatings is analytically modeled by an approach that takes into consideration contributions due to both thermal mismatch and oxide growth. Microstructural changes in the TBC system are correlated with measured stress trends through comparison with the modeled stresses. The stress measurements and modeling provide insight into failure modes and mechanisms, and to identify critical features in the measured stress data that can be used as indicators of failure in TBCs.

Emphasis is placed on the difference between quantum and classical dynamics, and correction techniques, which can be used to emulate quantum effects in a classical system, are investigated. We present molecular dynamics simulation results for liquid water using the 'Thole-type' all atom polarizable water model, which has previously been shown to give reasonable results for both ice Ih and small water clusters. We employ expressions for the density of states power spectrum in the liquid in either atomic or rigid-body coordinates that are appropriate for rigid molecule simulations. It is demonstrated that the atomic power spectra can be written as a linear combination of the center of mass and rotational power spectra via the use of the 'coupling matrix' of linear coefficients. This approach allows us to introduce the concept of 'fractional degrees of freedom' (DOF) for nuclei in rigid molecule simulation. Within this framework, it is illustrated that in a rigid water molecule the oxygen and hydrogen atoms have 2.82 and 1.59 DOF, respectively (for the TIP4P geometry). Within our suggested approach, we finally demonstrate that Debye-Waller factors can be obtained from the coupling matrix and show that quantum corrections to the structure can be accounted for by raising the temperature of the system in a classical simulation by approximately 50degrees, a result consistent with previous suggestions.

The ideal quasicrystals-forming composition Ti40Zr40Ni20 has been identified, which lies at the crossing point of the two specific lines, termed as e/a-constant and e/a-variant lines. Bulk quasicrystalline Ti/Zr-based alloys are obtained in region of (TixZr100-y)(100-y)Ni-y (43.75 less than or equal to x less than or equal to 81.25, y = 17, 20 in at.%) by copper mold casting. It was confirmed that Ti40Zr40Ni20 is the optimal QC-forming composition, where a nearly pure bulk quasicrystal rod, 6 mm in diameter, can be formed. With a small deviation from this ideal composition, the Ti(Zr) solid solution phases and/or C14-type Laves phase, though as minority phases, are found coexisting with the majority icosahedral phase. At the same time, the explanation of the e/a-variant line is explored. (C) 2004 Elsevier B.V. All rights reserved.

The melt-spun ribbons transform from an amorphous structure to a meta-stable quasicrystalline phase. This amorphous-to-quasicrystalline transition is not observed in amorphous powders obtained by mechanical milling. Since the mechanical milling process does not involve direct liquid phase formation of an amorphous structure, it is inferred that in the absence of the short-range order obtained directly from the liquid, meta-stable quasicrystalline phase formation is not energetically favored in these Zr-based metallic glasses.

The changing tiling pattern with elapsed time in the HRTEM image has been analyzed, and the spatial and temporal variations of the phason field have been deduced. In the temporal variation, abrupt and discrete changes have been observed in addition to smooth and continuous ones. The degrees of the spatial and temporal correlations of the phason fluctuation have been evaluated, both of which decrease continuously with increasing distance and time, respectively.

The response of a micro-thermal probe in contact with aperiodic and periodic surfaces in air reveals the anisotropic heat flow of the decagonal structure. Heat dissipation with the probe on the aperiodic surface is higher than when the probe is on the periodic surface. While the SThM technique is generally considered to be constrained to the surface region below the nominally 2-5 mum probe tip radius, the heat flow data obtained are clearly comprised of contributions from both the lateral surface around the probe tip and a volume normal to the surface in contact. Heat flow in the decagonal Al74Ni10Co16 quasicrystal can be modeled by an elliptical distribution of thermal diffusion. Parameters for the model used in this study were obtained by making bulk thermal diflusivity measurements using the laser flash method on specimens along the 2- and 10-fold directions. The model was applied to a surface oriented 45degrees to the major axes and verified from bulk measurements obtained from a sample cut along this orientation. (C) 2004 Elsevier B.V.

For decagonal quasicrystals, it has been proposed, however, that one can link the aperiodic and periodic directions using what are termed net planes [Acta Crystallogr. A 57 (2001) 333]. These net planes are thought to play a critical role in the stability and growth of decagonal quasicrystals. To explore their potential role during growth and to shed light on their structural stability, we have studied single-grain surfaces of decagonal Al-Ni-Co by low energy electron diffraction and scanning tunneling microscopy. Our results suggest that these planes do indeed have special stability. Published by Elsevier B.V. C1 Iowa State Univ Sci & Technol, Ames Lab, Dept Chem, Ames, IA 50011 USA.

We show that a very complicated inhomogeneous surface morphology may develop on the 5-fold surface prepared by ion sputtering and annealing cycles in UHV. Sputtering and sublimation both contribute to material removal on the surface. The sublimation takes place at the annealing temperature at sites of surface defects induced by mechanical polishing and sputtering in UHV. The surface is characterized by nano-sized clusters of about 40 nm in size which form terraces. Results give further evidence for the cluster-based structure of the i-AlPdMn QC.

In the regression analysis, the radiation-induced increase in yield stress, Deltasigma(YS), was expressed in the form of a power law: Deltasigma(YS) = h(dpa)(n), where h and n are the regression coefficients and dpa is displacements per atom. The log log plots of A,Deltasigma(YS) vs. dpa data showed two distinctive regimes: a low-dose regime where a rapid hardening occurs and a high-dose regime where the log-log plot shows a considerably reduced slope. Mean values for n obtained from the 19 metals were about 0.5 for the low-dose regime and about 0.12 for the high-dose regime. Some ductile metals like Fe, Cu and Zr displayed lower It and n values. Doses to reach the regime of reduced irradiation hardening.. D-S.. were in the range 0.003-0.07 dpa. Comparisons between radiation effect parameters led to a conclusion that the transition from the low-dose to the high-dose regime in irradiation hardening occurs either when the tensile specimen undergoes prompt plastic instability at yield or when saturation of defect cluster density occurs.

Materials chosen were the S-65C ITER candidate material produced by Brush Wellman, Kawecki Berylco Industries PO beryllium, and a high-purity zone refined beryllium. Minisheet tensile and thermal diffusivity specimens were irradiated in the temperature range of similar to100-300 degreesC with a fast (E > 0. 1 MeV) neutron fluence of 0.05-1.0 x 10(25) n/m(2) in the high flux isotope reactor (HFIR) at the Oak Ridge National Laboratory and the high flux beam reactor (HFBR) at the Brookhaven National Laboratory. As expected from earlier work on beryllium, both materials underwent significant tensile embrittlement with corresponding reduction in ductility and increased strength. Both thermal diffusivity and volumetric expansion were measured and found to have negligible changes in this temperature and fluence range. Of significance from this work is that while both materials rapidly embrittle at these ITER relevant irradiation conditions, some ductility (1-2%) remains, which contrasts with a body of earlier work including recent work on the Brush-Wellman S-65C material irradiated to slightly higher neutron fluence.

For temperatures below that where significant thermal annealing of defects occurs, an expression is derived for the fission density at which irradiation-induced recrystallization is initiated that is a thermal and weakly dependent oil fission rate. The initiation of recrystallization is to be distinguished from the subsequent progression and eventual consumption of the original fuel grain. The formulation takes into account the observed microstructural evolution of the fuel, the role of precipitate pinning and fission gas bubbles, and the triggering event for recrystallization. The calculated dislocation density, fission gas bubble-size distribution, and fission density at which recrystallization first appears are compared to measured quantities. (C) 2004 Elsevier B.V.

Therefore it is important and necessary to develop corrosion models to predict corrosion behaviours at the design stage of practical LBE coolant systems and to properly interpret and apply experimental results from test loops. In the present study, we extended a kinetic corrosion model for a simple LBE loop to a model for a loop with multiple modules to include effects of geometry variations. The model is applied to an ideal loop with contractions and expansions and a test loop named 'DELTA' set up in the Los Alamos National Laboratory. Analyses show the combined effects of the axial geometry variations and the axial temperature profile on the corrosion/precipitation distribution in the entire loop. The present study illustrates systematically different dependence of corrosion behaviours on the hydraulic factors in an open pipe flow, a simple loop flow and a multi-modular loop flow.

Since current treatment of trypanosome infections is difficult and often ineffective in controlling the chronic phases of these diseases, more effective anti-trypanosomal drugs are urgently needed. One class of polyamines containing hydrophobic side chains shows promise. However, conformational information regarding their interaction with the target enzyme trypanothione reductase has yet to be obtained. As prelude to such studies, we have made preliminary studies of novel spermine and spermidine analogs bearing one or two N-substituted 2-naphthylmethyl groups dissolved in aqueous solution. Our studies suggest the pH-dependent formation of fluorescent aggregates involving either the encounter of two excited-state naphthyl groups ("excimer") or formation of an excited-state complex ("exciplex") formed as a consequence of amine-to-naphthyl electron transfer. These spectral changes may be used to explore the mechanism by which N-(2-naphthylmethyl) polyamine analogs exert their toxic effects toward the design of improved candidates for anti-trypanosomal chemotherapy.

The results from the different tests are compared and statistically analyzed to determine the precision of each method and to estimate the significance of the differences among the four techniques. It was found that dynamic methods (RUS and IE) have superior precision and repeatability when compared to NI and 4PB for all four tested materials. It was also found that the differences between results of RUS and IE are not statistically significant, and that NI can be equally successfully used for determining Young's modulus of well-prepared, microstructurally homogenous and relatively hard materials. 4PB was found to have the lowest precision and repeatability among the four test methods.

The reaction of 1(BF4) with 1 equiv of aqueous KOH (0.01 M) affords the following mixture of mono-, di-, and tetranuclear compounds: [Cp"Ir( eta(4)-SC(Me)CHCHC(0)Me)] (3), (Cp*Ir)[Cp*Ir(eta(4)-SC-(Me)CHCHC(O)Me)](3)(BF4)(2) (4(BF4)), [(Cp*Ir)(2)(mu(2),eta(4)-SC(Me)CHCC(O)Me)](BF4) (5(BF4)), and [Cp*Ir(mu(2),eta(3)-SC(Me)CHCH2C(O)Me)](2)(BF4)(2) (6(BF4)). The H-1 and C-13 NMR data are consistent with the single-crystal X-ray diffraction structures of the cationic complexes 4(BF4), 5(OTf), and 6(BF4). These products are formed by a complex series of reactions that begin with the displacement of the 2,5-dimethylthiophene (2,5-Me2T) ligand from 1 and reaction of the resulting "[Cp*Ir](2+)" fragment with 3. In the synthesis of 8(BF4), the new complex [(Cp*Rh)(2)(mu(2), eta(4)=SC(Me)CHCC(O)Me)](BF4) (9(BF4)), analogous to 5(BF4), is produced. Studies of the reactions of [Cp*Rh(eta(5)-2,5-Me2T)](BF4)(2) (8(BF4)) with OH- and MeO- show a type of reactivity quite different from that observed for 1(BF4) and I(OTf). The solvolysis of 8(BF4) in acetone affords the mononuclear complex [Cp*Rh(OCMe2)(2)(OH)](BF4) (10(BF4)), whose crystal structure is described. Detailed NMR studies establish the pathways by which [Cp*Ir(eta(5)-2,5-Me2T)](2+) (1) and [Cp*Rh(eta(5)-2,5-Me2T)](2+) (8) react with H2O/OH- and MeOH/MeO- to give the variety of observed products.

However, at quadratic order, this asymptotic expansion produces an entire family of shallow water wave equations that are asymptotically equivalent to each other, under a group of nonlinear, non-local, normal-form transformations introduced by Kodama in combination with the application of the Helmholtz-operator. These Kodama-Helmholtz (KH) transformations are used to present connections between shallow water waves, the integrable fifth-order KdV equation, and a generalization of the Camassa-Holm (CH) equation that contains an additional integrable case. The dispersion relation of the full water wave problem and any equation in this family agree to fifth order. The travelling wave solutions of the CH equation are shown to agree to fifth order with the exact solution. (C) 2003 Elsevier B.V. All rights reserved. C1 Univ Sydney, Sydney, NSW 2006, Australia.

This has resulted in impressive moraines, paraglacial debris flow fans and terraces along the upper stretches of the Bhagirathi Valley. Cosmogenic radionuclide (CRN) dating of glacial and paraglacial landforms shows that fans, terraces and associated moraines formed approximately synchronously as the landscape readjusted to changing environmental conditions. This synchronicity suggests that fan and terrace formation is intimately related to glaciation, and that fluctuations in glacial and associated environments during times of climatic instability cause rapid sediment transfer and resedimentation of glacial landforms. The CRN dates show that all existing glacial and paraglacial landforms in the upper Bhagirathi Valley formed during the late Pleistocene and Holocene. This demonstrates that, in this high mountain environment, paraglacial and glacial landforms are eroded and resedimented within about 20,000 years. Furthermore, this testifies to the dynamic nature of glacial environments in monsoon-influenced high mountain regions. (C) 2004 Published by Elsevier B.V.

The K-shell vacancy states produced by photoionization of atomic carbon are identical to those produced by 1s --> 2p photoexcitation of a C+ ion: 1s2S(2) 2p(2) D-2, P-2, and S-2 autoionizing states occur in both cases. These vacancy states stabilize by emission of an electron to produce C2+ ions. Measurements are reported for the lifetime of the 1s2s(2) 2p(2) D-2, P-2 and S-2 autoionizing states of C+: 6.3 +/- 0.9 fs, 11.2 +/- 1.1 fs and 5.9 +/- 1.3 fs respectively. Knowledge of such lifetimes is important for comparative studies of the lifetimes of K-shell vacancies in carbon-containing molecules, benchmarking theory, and interpreting satellite x-ray spectra from astrophysical sources such as x-ray binaries. Absolute cross sections were measured for both ground-state and metastable-state ions providing a stringent test of state-of-the-art theoretical calculations.

This data set consists of delta(18)O results for 327 samples from surface outcrops, drill cores, and mine workings in a 3.5 km x 1.7 km x 1.0 km block in the hanging wall of the Comstock fault encompassing the region where the most important ore bodies were discovered. The delta(18)O contours deep in the hanging wall are not simply parallel to the Comstock fault or to the boundary of the Davidson granodiorite stock as would be expected for a hydrothermal convection system dominated by unicellular flow. Instead, the subsurface delta(18)O values exhibit a high degree of symmetry about a vertical plane directed radially toward the stock, with isotopic contours being predominantly perpendicular to the Comstock fault and the eastern contact of the Davidson granodiorite. A vertical cross section along the Comstock Lode shows a low delta(18)O core with two symmetrical zones of higher delta(18)O values to either side where the contours are steeply inclined, which we infer reflects downwelling of fluids shifted by water-rock exchange or steam loss. This 3-D visualization of delta(18)O values provides the first evidence that longitudinal convective rolls can be significant in geologic environments, in this case within a zone of high temperature gradients and permeability near the Comstock fault and the Davidson granodiorite stock.

Kr-81 ages range from similar to2 x 10(5) to similar to1 x 10(6) yr, correlate with Cl-36/Cl ratios, and are consistent with lateral flow of groundwater from a recharge area near the Uweinat Uplift in SW Egypt. Low delta(2)H values of the Kr-81-dated groundwater reveal a recurrent Atlantic moisture source during Pleistocene pluvial periods. These results indicate that the Kr-81 method for dating old groundwater is robust and such measurements can now be applied to a wide range of hydrologic problems.

Successful deposition and evaluation of a dodecanethiol MPN phase within a 1.3 m long, 100 mum x 100 mum square capillary is reported. The thickness of the MPN phase was evaluated using SEM analysis. An average thickness of 15 nm along the capillary walls was determined. While the film depth along the walls was very uniform. the corner depths were greater with the largest observed depth being 430 nm. Overall, an efficient chromatographic system was obtained with a minimum reduced plate height, h(min), of 1.2 for octane (k = 0.22). Characterization of the MPN column was completed using four compound classes (alkanes, alcohols, ketones, and aromatics) that were used to form a seven-component mixture with a 2-s separation. A mixture consisting of a nerve agent simulant in a sample containing analytes that may commonly interfere with detection was also separated in only 2 s, much faster than a similar separation previously reported using a muGC system requiring 50 s. A comparison of the MPN stationary phase to phases employed in previously reported muGC systems is also made. Application of the square capillary MPN column for a high-speed separation as the second column of a comprehensive 2-D gas chromatography system (GC x GC) was also explored. (C) 2004 Elsevier B.V.

The analysis was based on a search for gamma rays from the deexcitation of the residual nucleus that would result from the disappearance of either a proton or neutron from O-16. A limit of tau(inv)>2x10(29) yr is obtained at 90% confidence for either neutron- or proton-decay modes. This is about an order of magnitude more stringent than previous constraints on invisible proton-decay modes and 400 times more stringent than similar neutron modes.

This matrix model can be constructed from QCD by mapping it to an equivalent matrix model which has the same symmetries as QCD with chemical potential. Its microscopic spectral correlations are conjectured to be identical to those of the QCD Dirac operator. We investigate this conjecture by comparing large ensembles of Dirac eigenvalues in quenched SU(3) lattice QCD at a nonzero chemical potential to the analytical predictions of the matrix model. Excellent agreement is found in the two regimes of weak and strong non-Hermiticity, for several different lattice volumes.

A pure quantum state is entangled relative to such a subspace if its expectations are a proper mixture of those of other states. Many information-theoretic aspects of entanglement can be extended to this observable-based setting, suggesting new ways of measuring and classifying multipartite entanglement. By going beyond the distinguishable-subsystem framework, generalized entanglement also provides novel tools for probing quantum correlations in interacting many-body systems.

The symmetry breaking pattern and the mass spectrum resemble that in the standard model (SM). To leading order in the warp factor the rho parameter and the coupling of the Z (S parameter) are as in the SM, while corrections are expected at the level of a percent. From the anti-de Sitter (AdS) conformal field theory point of view the model presented here can be viewed as the AdS dual of a (walking) technicolorlike theory, in the sense that it is the presence of the IR brane itself that breaks electroweak symmetry, and not a localized Higgs on the IR brane (which should be interpreted as a composite Higgs model). This model predicts the lightest W, Z, and gamma resonances to be at around 1.2 TeV, and no fundamental (or composite) Higgs particles.

This quantity provides a determination of the neutral weak axial vector form factor of the nucleon, which can potentially receive large electroweak corrections. The measured asymmetry A=-3.51+/-0.57 (stat)+/-0.58 (syst) ppm is consistent with theoretical predictions. We also report on updated results of the previous experiment at Q(2)=0.091 (GeV/c)(2), which are also consistent with theoretical predictions.

The estimated vibrational entropy change per atom in the gamma-->alpha phase transition, DeltaS(vib)(gamma-alpha)approximate to(0.75+/-0.15)k(B), is about half of the total entropy change. The bulk modulus follows a power-law pressure dependence that is well described using the framework of electron-phonon coupling. These results clearly demonstrate the importance of lattice vibrations, in addition to the spin and charge degrees of freedom, for a complete description of the gamma-->alpha phase transition in elemental Ce.

Our major finding is that paramagnetic fluctuations prevail as T-->0 for all values of p, and that they are sensitive to dilution, indicating a cooperative spin motion. However, the percolation threshold p(c) is not a critical point for the fluctuations. We also find that the low temperature spectral density has a 1/f behavior, and that dilution slows down the spin fluctuations. C1 Technion Israel Inst Technol, Dept Phys, IL-32000 Haifa, Israel.

In the first version each site has exactly one random link of strength p, while in the second one each site on average has p links of unit strength. We construct a perturbative description for the width of the stationary-state surface (a measure of synchronization), in the weak- and sparse-coupling limits, respectively, and verify the results by performing exact numerical diagonalization. The width remains finite in the limit of infinite system size for both cases, but exhibits anomalous scaling with p in the latter for dless than or equal to2.

When the density of electrons in the wire is very low, they arrange in a finite-length Wigner crystal. In this regime the electron spins form an antiferromagnetic Heisenberg chain with an exponentially small coupling J. An electric current in the wire perturbs the spin chain and gives rise to a temperature-dependent contribution of the spin subsystem to the resistance.

Pohl et al., Nature (London) 397, 238 (1999)]. Time-resolved scanning tunneling microscopy reveals that this nanometer-scale restructuring occurs by a cooperative mechanism involving the sequential formation of triangular regions with fcc and hcp stacking. Using a 2D Frenkel-Kontorova model, we can simulate the creation of these triangular building blocks via basic dislocation motions and reactions. C1 Sandia Natl Labs, Livermore, CA 94550 USA.

As a consequence of pair correlations in the superconducting state, the spin displays a rich and unusual dynamics. To properly describe the time evolution of the spin we find the generalized Wess-Zumino-Witten-Novikov term in the effective action for the spin on the Keldysh contour. The superconducting correlations lead to an effective spin action which is nonlocal in time leading to unconventional precessions. Our predictions might be directly tested for macroscopic spin clusters. C1 Los Alamos Natl Lab, Div Theoret, Los Alamos, NM 87545 USA.

Inclusion of such novel adatom ascending processes in kinetic Monte Carlo simulations of Al(110) homoepitaxy as a prototypical model system can lead to the existence of an intriguing faceting instability, whose dynamical evolution and kinetic nature are explored in comparison with experimental observations.

In silicate glasses, the network formers are based on SiO4 tetrahedra interconnected through oxygen atoms at the corners. Conventional wisdom implies that alkaline and alkaline-earth orthosilicate materials cannot be vitrified, because they do not contain sufficient network-forming SiO2 to establish the needed interconnectivity. We studied a bulk magnesium orthosilicate glass obtained by containerless melting and cooling. We found that the role of network former was largely taken on by corner and edge sharing of highly distorted, ionic Mg-O species that adopt 4-, 5-, and 6-coordination with oxygen. The results suggest that similar glassy phases may be found in the containerless environment of interstellar space. C1 Argonne Natl Lab, Argonne, IL 60439 USA.

The mechanisms of synthesis are poorly understood but are of great interest for engineering novel materials. We use spectromicroscopy to show that microbially generated submicrometer-diameter iron oxyhydroxide (FeOOH). laments contain polysaccharides, providing an explanation for the formation of akaganeite pseudo-single crystals with aspect ratios of similar to1000:1. We infer that the cells extrude the polysaccharide strands to localize FeOOH precipitation in proximity to the cell membrane to harness the proton gradient for energy generation. Characterization of organic compounds with high spatial resolution, correlated with mineralogical information, should improve our understanding of biomineralization mechanisms.

Morphology changes of the monolayer caused by the laser pump pulse are monitored by transmission electron microscopy. At low pump power, the monolayer maintains its structural integrity. Hot electrons induced by the pump pulse decay through electron-phonon (e-ph) coupling inside the nanocrystals with a decay constant that is similar to the value for bulk films. At high pump power, irreversible particle aggregation and sintering occur in the nanocrystal monolayer, which cause damping and peak shifting of the transient bleach signal.

They have been proposed as remnants of coronal plumes. If true, they should reflect the observation that plumes are rooted in unipolar magnetic flux concentrations in the photosphere and are heated as oppositely directed flux is advected into and reconnects with the flux concentration. A minimum variance analysis (MVA) of magnetic discontinuities in PBSs showed there is a larger proportion of tangential discontinuities than in the surrounding high-speed wind, supporting the hypothesis that plasmoids or extended current sheets are formed during reconnection at the base of plumes. To further evaluate the character of magnetic field discontinuities in PBSs, differential streaming between alpha particles and protons is analyzed here for the same sample of PBSs used in the MVA. Alpha particles in high-speed wind generally have a higher radial flow speed than protons. However, if the magnetic field is folded back on itself, as in a large-amplitude Alfven wave, alpha particles will locally have a radial flow speed less than protons. This characteristic is used here to distinguish between folded back magnetic fields (which would contain rotational discontinuities) and tangential discontinuities using Ulysses high-latitude, high-speed solar wind data. The analysis indicates that almost all reversals in the radial magnetic field in PBSs are folded back field lines. This is found to also be true outside PBSs, supporting existing results for typical high-speed, high-latitude wind. There remains a small number of cases that appear not to be folds in the magnetic field and which may be flux tubes with both ends rooted in the Sun. The distinct difference in MVA results inside and outside PBSs remains unexplained. C1 NASA, George C Marshall Space Flight Ctr, Huntsville, AL 35812 USA.

The data show that the primary photodissociation channel is cleavage of the O-Cl bond to produce Cl atoms and CH3O radicals, a result consistent with the direct dissociation mechanism found by other computational and experimental studies of alkyl hypohalites. Photofragment translational spectroscopy with a crossed laser-molecular beam apparatus, coupled with tunable VUV photoionization detection, identified the momentum-matched products at m/e = 35 (Cl+ from Cl atoms) and m/e = 29 (the CHO+ daughter ion of CH3O). Products were formed with a narrow range of recoil kinetic energies, peaking at 48 kcal/mol in the center-of-mass reference frame, with a full-width half-maximum of 4 +/- 2 kcal/mol. This kinetic energy distribution shows that the CH3O products are formed with a very narrow range of internal energies, and a simple model shows that to conserve angular momentum this internal energy, near 20 kcal/mol, is partitioned primarily to rotational energy. Thus CH3OCl could serve as a photolytic precursor of CH3O radicals with high and well-defined rotational and translational energies. C1 Univ Chicago, James Franck Inst, Chicago, IL 60637 USA.

The C2H radical is prepared by 193-nm photolysis of acetylene, and the C2H concentration is monitored using CH(A (2)Delta) chemiluminescence from the C2H + O-2 reaction. The rate constants at low and high temperatures are k(1) = (1.3 +/- 0.3) x 10(-10) and (1.0 +/- 0.2) x 10(-10) for isobutane, k(2) = (2.1 +/- 0.4) x 10(-10) and (2.2 +/- 0.4) x 10(-10) for 1-butene, k(3) = (1.4 +/- 0.3) x 10(-10) and (1.2 +/- 0.2) x 10(-10) for isobutylene, and k(4) = (2.9 +/- 0.6) x 10(-10) and (3.3 +/- 0.6) x 10(-10)) for 1,3-butadiene at T = 104 and 296 K, respectively (in units of cm(3) molecule(-1) s(-1)). Comparison with existing data shows a trend of a decrease in activation energy with increasing size of the hydrocarbon chain. For these reactions of hydrocarbons containing four carbon atoms, the activation energy is zero within experimental uncertainty, and the rate constants do not depend on temperature in the 104-296 K temperature range. The rate constants for C2H reactions with methyl cyanide, ethyl cyanide, and propyl cyanide are measured at three temperatures, 104, 165, and 298 K. Measured rate constants are fit to an Arrhenius expression and are k(5) = (1-8 +/- 0.35) x 10(-11) exp(-766 +/- 38/T), k(6) = (1.5 +/- 0.3) x 10(-11) exp(-145 +/- 10/T, and k(7) = (2.1 +/- 0.4) x 10(-11) exp(-51 +/- 4/T) (in units of cm(3) molecule(-1) s(-1), T is in Kelvin). At T = 296 K, k(3), k(5), k(6), and k(7) are measured as a function of total pressure and show no pressure dependence in the 0.6-8 Torr (0.08-1.07 kPa) pressure range. Results from this work are compared with the results of previous investigations of C2H reactions at low temperature and are discussed in relation to the atmospheres of Saturn and Titan.

Difficulties encountered along the way include uncertain mode identifications and a lack of stable pulsation mode properties. Here we report on Feige 48, an sdBV star for which follow- up observations have been obtained spanning more than four years. These observations show some stable pulsation modes. We resolve the temporal spectrum into five stable pulsation periods in the range 340- 380 s with amplitudes less than 1 per cent, and two additional periods that appear in one data set each. The three largest amplitude periodicities are nearly equally spaced, and we explore the consequences of identifying them as a rotationally split l = 1 triplet by consulting a representative stellar model. The general stability of the pulsation amplitudes and phases allows us to use the pulsation phases to constrain the time- scale of evolution for this sdBV star. Additionally, we are able to place interesting limits on any stellar or planetary companion to Feige 48. C1 SW Missouri State Univ, Dept Phys Astron & Mat Sci, Springfield, MO 65804 USA.

We show that the observed cluster magnetic field could reduce the SZ power spectrum by 20 per cent at l similar to 4000, where the SZ power spectrum will be precisely measured by the Sunyaev-Zel'dovich array (SZA) and the Atacama Cosmology Telescope (ACT). At smaller scale, this effect is larger and could reach a factor of several. Such an effect must be considered for an unbiased interpretation of the SZ data. Although the magnetic effect on the SZ power spectrum is very similar to that of radiative cooling, it is measurable by multiband cosmic microwave background polarization measurement.

The proper-motion measurements are based on 138-555 I-band images taken during four observing seasons: 1997-2000. The catalogue stars are in the magnitude range 11 < I < 18 mag. In particular, the catalogue includes red clump giants and red giants in the GB, and main-sequence stars in the Galactic disc. The proper motions up to mu = 500 mas yr(-1) were measured with a mean accuracy of 0.8- 3.5 mas yr(-1), depending on the brightness of a star. This catalogue may be useful for studying the kinematics of stars in the GB and the Galactic disc. C1 Princeton Univ Observ, Princeton, NJ 08544 USA. Univ Warsaw Observ, PL-00478 Warsaw, Poland.

The project Cryogenic Underground Observatory for Rare Events (CUORE), proposed as a natural extension of MI-DBD, will be a tightly packed array of 1000 TeO2 bolometers, each being a cube 5 cm on a side with a mass of 790 g. The array will consists of 25 vertical towers, arranged in a square of 5 towers by 5 towers, each containing 10 layers of 4 crystals. A single CUORE tower has been constructed as a smaller scale experiment called CUORICINO. The technical feasibility of CUORE is now being tested in CUORICINO, running since few weeks. The CUORICINO experiment consists of 44 TeO2 detectors 5 x 5 x 5 cm(3) and 18 TeO2 detectors 3 x 3 x 6 cm(3) for a total mass of approximately 41 kg. An analysis of the detector performances is presented together with the new limit obtained on neutrinoless double beta decay of Te-130. (C) 2003 Elsevier B.V. All rights reserved.

We find that the energy resolution does not always degrade with increasing energy. The best energy resolution of 5.7 +/- 0.9 eV at 6.4 keV is obtained, which is possibly even better than the baseline width of 6.5 +/- 0.2 eV. Assuming that the noise level is determined by the noise spectrum NS(f; R similar to R + dR(E)) considering the resistance change of dR(E), instead of NS(f; R) at the operating point, these results may be explained by the fact that the noise decreases at the higher TES resistance. The pulse variation appears to have a minimum at a certain resistance of R + dR(E) similar or equal to 48 mOmega, and the best energy resolution for each line is obtained at such an operating point, respectively. The pulse variation could be enhanced when the fluctuation of the TES sensitivity a is large at R + dR(E). (C) 2003 Elsevier B.V. All rights reserved.

We find that the sensitivity alpha equivalent to R/T dR/dT of the TES varies significantly along the superconducting-to-normal transition that the bias point traverses during a pulse. Furthermore, alpha is reduced significantly during a pulse compared to its equilibrium value calculated from the DC characteristics. This leads to an overestimate of the expected energy resolution when basing the prediction on the equilibrium sensitivity. (C) 2003 Elsevier B.V. All rights reserved.

The TES instrument will operate in the similar to 500-1500 eV EUV/soft X-ray bandpass, obtaining similar to 3 eV energy-resolved spectra at similar to 6.25 arcsec image resolution with a count rate of similar to 1000 photons/sec/pixel. Over a typical observation period of similar to 360 sec, we will raster scan over a 0.6 x 0.6 arcmin field of view to obtain a 6 x 6 pixel image containing true EUV/soft X-ray spectroheliograms of a solar active region. Using these observations, we can directly determine composition, electron density and thermal differential emission measure of large active region loops in order to constrain models of beating mechanisms and accurately measure the thermal morphology of these structures. In the current analysis, we present an initial instrument concept and discuss some of the mission science goals. (C) 2003 Elsevier B.V. All rights reserved. C1 Stanford Univ, Stanford, CA 94305 USA.

Microstrip filters are used to define the frequency band of the optical response, which is centered at 217 GHz with 40% bandwidth. The microstrip is terminated into a load resistor on a silicon nitride suspension, adjacent to a TES which is used to measure the dissipated power.

However, readout of these arrays remains a major instrumental challenge. We address this challenge using frequency-domain multiplexing of signals from an array of superconducting transition-edge sensors (TES). Each TES sensor is connected in series with an LC tuned circuit and biased with an alternating current at a selected frequency, ranging from 380 kHz to 1 MHz. The signal from each sensor amplitude-modulates its respective bias current. The LC filter reduces the bandwidth of the Johnson noise from the remaining sensors. The signals are combined at a current summing node and measured with a single superconducting quantum interference device (SQUID) array (100 elements). We have developed a custom SQUID controller with a measured slew rate of 10(7) Phi(0)/s at 1 MHz. We designed and fabricated photolithographed LC filters. With these filters we have demonstrated multiplexing with two TES sensors and are preparing to scale up to 32 sensors. (C) 2003 Elsevier B.V. All rights reserved.

The CABBAGE eliminates the AC carrier significantly, thus enables us to study the AC responses of the TES with high sensitivity. We tested two kinds of TES devices operating at 110 and 440 mK, respectively. With the 110 mK device biased with 25 kHz, an energy resolution of 28 eV is obtained for Mn Kalpha line. On the other hand, we multiplexed the signals from two 440 mK device biased with 50 and 20 kHz, respectively, and obtained 167 and 271 eV energy resolutions. Even at the balance point of the bridge, AC signal did not disappear and odd-order harmonics were observed. They are considered to arise from the current dependence of the TES resistance, which is characterized by beta equivalent to log R/d log I. Numerical solution for the CABBAGE response can reproduce the experimental results well if beta equivalent to 0.24 +/- 0.02. Since the harmonics may cause severe problem in the SQUID operation even after attenuated by a bandpass filter, especially at high bias frequency operation such as several hundred kHz, it is important to make beta small.

Two areas where they have found initial application are X-ray absorption spectroscopy (XAS) and time-of-flight mass spectrometry (TOF-MS). In synchrotron-based fluorescence-detected XAS cryogenic detectors are used to examine the role of metals in biological systems by measuring their oxidation states and ligand symmetries. In TOF-MS cryogenic detectors increase the sensitivity for biomolecule detection and identification for masses above similar to50kDa, and thus enable TOF-MS on large protein complexes or even entire viruses. More recently, cryogenic detectors have been proposed as optical sensors for fluorescence signals from biomarkers. We discuss the potential for cryogenic detectors in biological research, as well as the challenges the technology faces. (C) 2003 Elsevier B.V. All rights reserved.

transverse momentum at HERA SO PHYSICS LETTERS B LA English DT Article ID DEEP-INELASTIC SCATTERING; LUND MONTE-CARLO; CENTRAL TRACKING DETECTOR; HIGH-ENERGY LEPTON; CROSS-SECTIONS; EP COLLISIONS; PARTON DISTRIBUTIONS; HADRON-COLLISIONS; JET FRAGMENTATION; BOSON PRODUCTION AB A search for events containing isolated tau leptons and large missing transverse momentum, not originating from the tau decay, has been performed with the ZEUS detector at the electron-proton collider HERA, using 130 pb(-1) of integrated luminosity. A search was made for isolated tracks coming from hadronic tau decays. Observables based on the internal jet structure were exploited to discriminate between tau decays and quark- or gluon-induced jets. Three tau candidates were found, while 0.40(-0.13)(+0.12) were expected from Standard Model processes, such as charged current deep inelastic scattering and single W+/- -boson production. To search for heavy-particle decays, a more restrictive selection was applied to isolate tau leptons produced together with a hadronic final state with high transverse momentum. Two candidate events survive, while 0.20 +/- 0.05 events are expected from Standard Model processes. (C) 2004 Published by Elsevier B.V. C1 Argonne Natl Lab, Argonne, IL 60439 USA.

The result uses a revised analysis of data from the SAMPLE experiment which was carried out at the MIT-Bates Laboratory. The data are combined with a calculation of the proton's axial form factor-G(A)(e) to determine the strange form factor G(M)(s) (Q(2) = 0.1) = 0.37 +/- 0.20 +/- 0.26 +/- 0.07. The extrapolation of G(M)(s) to its Q(2) = 0 limit and comparison with calculations is also discussed. (C) 2004 Published by Elsevier B.V. C1 Univ Illinois, Dept Phys, Urbana, IL 61801 USA.

Following the same procedure as in the previous analyses for scalar and pseudo-scalar mesons, we derive the bound-state equations of a q (q) over bar system in the vector channel. We include the lowest order effects of the vector interaction. The resulting transverse and longitudinal components of the bound-state equation look different from each other. But eventually after imposing an appropriate cutoff, one finds these two are identical, giving the same mass and the same (spin-independent) light-cone wavefunction. Mass of the vector meson decreases as one increases the strength of the vector interaction. (C) 2004 Published by Elsevier B.V. C1 Hokkaido Univ, Meme Media Lab, Sapporo, Hokkaido 0608628, Japan.

We show that taking properly into account the flavor structure of relevant SU(3) representations for arbitrary number of colors enhances the nonleading term by an additional factor of N-C, making the cancellation consistent with the N-C counting. Moreover, we show that, for the same reason, Theta(+) width is suppressed by a group-theoretical factor O(1/N-C) with respect to Delta and discuss the N-C dependence of the phase space factors for these two decays.

Using the most sensitive ground-based detection of GRBs, the sample extends to GRBs much fainter than those detected by the onboard trigger, but because of the temporal resolution of the data, the sample is limited to GRBs of duration of at least 2 s. For each detected event, Bayesian probabilities are calculated for the event to belong to each of seven classes of differing physical origins. The sample of GRB candidates is defined by the requirement that the Bayesian probability for belonging to the GRB class is higher than 0.5. The intensity distribution of the GRB sample is corrected using a Monte Carlo simulation of the postflight detection efficiency. The sky distribution of the dimmest BATSE bursts is consistent with isotropy. The dimmest bursts are softer than the brightest triggered bursts.

The spin evolution of this pulsar is found to experience extreme episodic discontinuities in its spin-down rate during the 2.6 yr campaign. The rate of occurrence of these timing glitches is 2.3 per year, comparable to the highest seen for any pulsar. The mean glitch amplitude produced a fractional change in the frequency of Deltanu/nu = 0.36 x 10(-6) and in the frequency derivative of Delta(nu) over dot/(nu) over dot = 3 x 10(-4). Despite this prodigious timing activity, we are able to derive a phase-connected timing solution between glitch events with an average spin-down rate of - 1.9743 x 10(-10) Hz s(-1). The integrated effect of the glitches in. (nu) over dot was so large that the apparent characteristic age of the pulsar (-nu/2(nu) over dot) decreased significantly during the campaign. We discuss the implications of a large glitch activity and high braking index on the spin evolution of young pulsars.

This phenomenon, called "spontaneous scalarization," causes the ( Einstein frame) scalar field inside a neutron star to rapidly become inhomogeneous once the star's mass increases above some critical value. For a star whose mass is below the threshold, the field is instead nearly uniform ( a state that minimizes the star's energy) and the configuration is similar to the general relativity one. Here we show that the spontaneous scalarization phenomenon is linked to another strong-field effect: a spontaneous violation of the weak energy condition.

In both cases, the physical properties were calculated using existing published force fields not specifically tuned to the problem at hand. No assessment of the accuracy of our predictions was made until the experimental values for each problem set were announced at the end of the competition. Liquid densities were computed for the Part 2 problem set using the Towhee Monte Carlo molecular simulation program and the Amber96, Charmm22, Compass, and OPLS-aa force fields. No single force field was able to provide parameters for all the molecules in the problem set, but the Amber96 force field had the best results of the four tested and a reasonable coverage of the problem set. Viscosities were computed for the Part 3 problem set using the LAMMPS molecular dynamics code. The Towhee program was used to generate equilibrium starting configurations. Only one force field, OPLS-aa, was used. The predicted viscosities showed average deviation of about 35% from the experimental values.

There are no data, however, that document resistance of such soils to acidic deposition exposure on a timescale longer than 30-40 years. In this paper, we report on directly testing the long-term buffering capacity of nineteenth century forest soils developed on calcareous silt loam. In a chemical analysis comparing archived soils with modern soils collected from the same locations similar to100 years later, we found varying degrees of forest-soil acidification in the taiga and forest steppe regions. Land-use history, increases in precipitation, and acidic deposition were contributing factors in acidification. The acidification of forest soil was documented through decreases in soil pH and changes in concentrations of exchangeable calcium and aluminum, which corresponded with changes in communities of soil microfauna. Although acidification was found at all three analyzed locations, the trends in soil chemistry were most pronounced where the highest loading of acidic deposition had taken place.

Metallography, X-ray diffraction, tensile test, and recrystallization studies indicate that the Co-17 at.% Mn alloy has a two-phase (FCC/HCP) structure with an ultimate tensile strength of 670 MPa and 40% elongation. The recrystallization temperature is approximately 620degreesC. The plane strain fracture toughness (K-1C) for AlMgB14 was estimated using the Palmquist method, both with and without the Co-Mn binder phase alloy. Results show that the fracture toughness of the monolithic boride without binder ranges from 3 to 4 MPa rootm, which is increased to 7-9 MPa rootm upon addition of the binder. The high ductility and tensile strength of the Co-Mn solid solution alloy, combined with its excellent wettability on boron-based compounds is expected to make this binder composition compatible with other boride ceramics.

The Te-O, Zn-O and Nb-O coordination numbers are determined by Gaussian fitting of the first-neighbour peaks in the neutron and x-ray data simultaneously. The transition of TeO4 to TeO3 units with increasing fraction of a second component is indicated by decreasing total TeO coordination numbers. This transition appears different for glasses with ZnO or Nb2O5 additions. Details of the Te-O peaks suggest there are two species of Te-O bonds with lengths of similar to0.19 and similar to0.21 nm. The change of their fractions shows excellent agreement with the existence of TeO4 trigonal bipyramids and TeO3 trigonal pyramids. All oxygen atoms from ZnO and Nb2O5 are used for rupture of Te-O-Te bridges, which is accompanied with a change of nearly all participating TeO4 to TeO3 groups. The tendency for a TeO4 --> TeO3 change decreases for glasses of higher second component content which is accompanied by the occurrence of TeO4 groups with non-bridging oxygens. The Nb tellurite glasses show transition to network-forming behaviour with the formation of Nb-O-Nb bridges. The fractions of TeO3 units of ternary Zn/Nb tellurite glasses agree with an additivity behaviour of the modifying effects of ZnO and Nb2O5 additions.

SO JOURNAL OF PHYSICS-CONDENSED MATTER LA English DT Review ID MAGNETIC DOTS; FE-GRATINGS; ARRAYS; LIGHT AB The experimental and theoretical aspects of obtaining the magnetic information carried by laser beams diffracted from an array of nanosized magnetic objects are reviewed. Experimentally it will be shown that the magneto-optic Kerr effect (MOKE) hysteresis loops recorded for diffracted beams can be quite different from those recorded for the reflected beam. We will show that the diffracted MOKE (D-MOKE) loops are proportional to the magnetic form factor or, equivalently, to the Fourier component of the magnetization corresponding to the reciprocal lattice vector of the diffracted beam. In conjunction with micromagnetic simulations, the D-MOKE provides a powerful and non-destructive technique for investigating the magnetization reversal process in submicron-sized magnetic particles. The advantages and disadvantages of the D-MOKE technique will be compared to those of other techniques that yield related information (e.g. magnetic force microscopy, Lorentz electron microscopy and micromagnetic simulations).

Minimally invasive analysis of single live MCF-7 cells for caspase-9 activity is demonstrated using the optical sensor which employs a modification of an immunochemical assay format for the immobilization of nonfluorescent enzyme substrate, Leucine-GlutamicAcid-Histidine-AsparticAcid-7-amino-4-methylcoumarin (LEHD-AMC). LEHD-AMC covalently attached on the nanoprobe tip of an optical sensor is cleaved during apoptosis by caspase-9 generating free AMC. An evanescent field is used to excite cleaved AMC and the resulting fluorescence signal is detected. By quantitatively monitoring the changes in fluorescence signals, caspase-9 activity within a single living MCF-7 cell was detected. By comparing of the fluorescence signals from apoptotic cells induced by photodynamic treatment and nonapoptotic cells, we successfully detected caspase-9 activity, which indicates the onset of apoptosis in the cells.

A uniform crust is studied because many exact analytical relations hold between the various response fields in this case. The initial stress field that is created immediately following the earthquake subsequently relaxes through time as the fluid pressure equilibrates by fluid flow. Maps of the electric field generated due to the fluid flow (electrokinetic coupling) are presented. Using conservative estimates of the various parameters involved, electric fields significantly larger than the diurnal (magnetotelluric) fields are generated. Quantitative results for how various components of the stress tensor change due to the fluid equilibration are also presented. The Coulomb stress can easily change by 100% (and more) in the months following an earthquake due to the fluid-pressure equilibration. C1 Univ Rennes 1, Equipe Geophys, F-35042 Rennes, France.

Quiescent isothermal crystallization, at relatively low crystallization temperatures, of low molecular weight nylon-6 samples, although poorly defined, predominantly developed the alpha crystalline form. Linear heating of these samples gave place to a single melting endotherm. An increase in crystallization temperature developed a better-defined a form with the single melting behavior continuing up to temperatures where a small endotherm appeared immediately after the crystallization temperature. A sequential increase of crystallization temperature (paralleled by increased definition of the alpha crystalline form) rendered triple melting behavior. This latter phenomenon was followed by the return of double melting at the expense of the third melting endotherm. after isothermal crystallization at higher temperatures. High molecular weight samples predominantly developed the gamma form at low isothermal crystallization temperatures, the melting behavior giving rise to the formation of a new melting endotherm with melting point slightly lower than the high endotherm previously observed with the low molecular weight sample. In addition, there was also the formation of a lower amount of a third melting endotherm. On the basis of these results, an explanation is given for each melting endotherm. It was also determined that, on heating, nylon-6 can recrystallize from the less stable gamma form to the more stable a form within a process parallel to melting. From a comparison of the crystallization results for different molecular weights, under the stable a crystal habit, it was determined that the basic concepts of the steplike crystallization and melting mechanism can also be applied to the complex melting behavior of the polymorphic nylon-6.

The expression is simple and contains one additional, temperature-independent constant that is a measure of the ensemble-averaged deviations of the scattering lengths of the two blocks from their mean values. The kind of nonuniformity considered here is a natural consequence of many of the popular synthetic routes used to obtain deuterium labeled block copolymers. Small-angle neutron-scattering experiments were conducted on a block copolymer obtained by saturating the double bonds of an anionically synthesized polydiene precursor with deuterium. The scattering data from our block copolymer in the disordered state are qualitatively inconsistent with all of the previously published theories on block copolymer thermodynamics. The data are, however, in quantitative agreement with the proposed expression. This enables a quantitative estimate of the nonuniformity of the deuterium labels in the sample.

The PRISM integral equations for the solution were solved self-consistently for the polyethylene intramolecular chain structure and intermolecular polymer and solvent correlations at various mole fractions. We found that explicitly considering the solvent molecules leads to considerably more short-range structure in the radial distribution function of the polymer, relative to the polymer without solvent at the same concentration. The long-range intermolecular correlations between polymer sites in the correlation hole regime decreased inversely with the polymer concentration as expected. The solvent/solvent radial distribution function, however, showed unexpected changes in shape and intensity as the polymer concentration increased. By using the direct correlation functions from PRISM theory, along with the random phase approximation, we estimated the spinodal temperatures as a function of polymer concentration. PRISM theory, which includes compressibility and nonrandom mixing effects, predicted a significantly higher critical temperature than was obtained from the corresponding incompressible Flory-Huggins theory. The PRISM spinodal curves were in reasonable agreement with experimental dissolution temperatures for octacosane in benzene. C1 Sandia Natl Labs, Albuquerque, NM 87185 USA.

Mechanical fatigue tests were conducted under R = -1 conditions on specimens machined at different locations in the casting at total strain amplitudes ranging from 0.02% to 0.5%. Fracture surfaces of specimens that failed in the high cycle fatigue regime with lives spanning two orders of magnitude were examined using a scanning electron microscope. The difference in lives for the Mg specimens was primarily attributed to a drastic difference in nucleation site sizes, which ranged from several hundred put's to several mm's. A secondary effect may include the influence of average secondary dendrite arm spacing and average grain size. At low crack tip driving forces (K-max < 3.5 MPa rootm) intact particles and boundaries act as barriers to fatigue crack propagation, and consequently the cracks tended to avoid the interdendritic regions and progress through the cells, leaving a fine striated pattern in this single-phase region. At high driving forces (K-max > 3.5 MPa rootm) fractured particles and boundary decohesion created weak paths for fatigue crack propagation, and consequently the cracks followed the interdendritic regions, leaving serrated markings as the crack progressed through this heterogeneous region. The ramifications of the results on future modeling efforts are discussed in detail. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

We compare doping in organic and inorganic semiconductors and show that the superlinear increase in conductivity with doping density should be a universal characteristic of excitonic semiconductors. The binding energy of the dopant electron to its conjugate cation in highly ordered perylene diimide films controls the free carrier density. The binding energy decreases with increasing dopant concentration because the neutral dopants increase the polarizability of the film. (C) 2004 American Institute of Physics.

The addition of ferrocene, an effective precursor for in situ Fe formation, was found to enhance carbon nanotube growth rates and extend growth to 3.25 mm thick carbon nanotube films. Ferrocene was introduced into the gas stream by thermal evaporation concurrently with acetylene using a specially constructed source. The key factor facilitating the growth of thick carbon nanotube films was the independent and precise control of the ferrocene amount in the feedstock. The carbon nanotube films were characterized by scanning and transmission electron microscopy, and Raman spectroscopy. The temperature dependence of the carbon nanotube growth with ferrocene exhibits a steep drop at high substrate temperatures and a loss of vertical alignment at 900 degreesC. The negative temperature coefficient of the growth rate suggests that the reaction mechanism of vertically aligned carbon nanotube growth is governed by a heterogeneous intermediate step.

PCCFM is applied to determine single-channel conformational dynamics by probing single-pair fluorescence resonant energy transfer, fluorescence self-quenching, and anisotropy of the dye-labeled gramicidin ion channel incorporated in an artificial lipid bilayer. Hidden conformational changes were observed, which strongly suggests that multiple intermediate conformation states are involved in gramicidin ion channel dynamics.

The cantilever was twisted laterally without any normal load by inducing the Lorentz force. An electrical current was applied to the cantilever in a magnetic field, and the torsional resonance frequency of the cantilever was obtained. Based on the observation that the torsional resonance frequency is the same as the second resonance peak of the thermally vibrating cantilever, the ratio of deflection spring constant to torsional spring constant is easily obtained from a simple relationship. For the cantilever used here, the torsional spring constant is 11.24 N/m, 28 times greater than the deflection spring constant. (C) 2004 American Institute of Physics.

Recent species-wide data for protein-protein interactions and transcriptional regulations allow us to assess the effect of gene duplication on robustness and plasticity of these molecular networks. Results: We demonstrate that the transcriptional regulation of duplicated genes in baker's yeast Saccharomyces cerevisiae diverges fast so that on average they lose 3% of common transcription factors for every 1% divergence of their amino acid sequences. The set of protein-protein interaction partners of their protein products changes at a slower rate exhibiting a broad plateau for amino acid sequence similarity above 70%. The stability of functional roles of duplicated genes at such relatively low sequence similarity is further corroborated by their ability to substitute for each other in single gene knockout experiments in yeast and RNAi experiments in a nematode worm Caenorhabditis elegans. We also quantified the divergence rate of physical interaction neighborhoods of paralogous proteins in a bacterium Helicobacter pylori and a fly Drosophila melanogaster. However, in the absence of system-wide data on transcription factors' binding in these organisms we could not compare this rate to that of transcriptional regulation of duplicated genes. Conclusions: For all molecular networks studied in this work we found that even the most distantly related paralogous proteins with amino acid sequence identities around 20% on average have more similar positions within a network than a randomly selected pair of proteins. For yeast we also found that the upstream regulation of genes evolves more rapidly than downstream functions of their protein products. This is in accordance with a view which puts regulatory changes as one of the main driving forces of the evolution. In this context a very important open question is to what extent our results obtained for homologous genes within a single species (paralogs) carries over to homologous proteins in different species (orthologs).

An adsorbed-[Ru(vbpy)(2)(dcb)](PF6)(2)/poly-[Ru(vbpy)(3)](PF6)(2) surface composite displays excellent stability toward dissolution in water, but the added overlayer film greatly decreases incident photon-to-current conversion efficiencies (IPCE) in propylene carbonate with I-3(-)/I- as the carrier couple. An ads[Ru(vbpy)(2)(dcb)](PF6)(2)/poly-[Zn(vbpy)(3)](PF6)(2) composite displays no loss in IPCE compared to ads-[Ru(vbpy)(2)(dcb)](PF6)(2) but is susceptible to film breakdown in the presence of water by solvolysis and loss of the cross-linking Zn2+ ions.
