AB We describe a revolutionary new approach to high spectral resolution soft x-ray optics. Conventionally in the soft x-ray energy range, high spectral resolution is obtained by use of a relatively low line density grating operated in 1(st) order with small slits. This severely limits throughput. This limitation can be removed by use of a grating either in very high order, or with very high line density, if one can maintain high diffraction efficiency. We have developed a new technology for achieving both of these goals which should allow high throughput spectroscopy, at resolving powers of up to 10(6) at 1 keV. Such optics should provide a revolutionary advance for high resolution lifetime free spectroscopy, such as RIXS, and for pulse compression of chirped beams. We report recent developmental fabrication and characterization of a prototype grating optimized for 14.2 nm EUV light. The prototype grating with a 200 nm period of the blazed grating substrate coated with 20 Mo/Si bilayers with a period of 7.1 nm demonstrates good dispersion in the third order (effective groove density of 15,000 lines per mm) with a diffraction efficiency of more than 33%.

DE Mini beam; Mini Collimator; Goniostat; Active beam stop
AB Recently, several important structures have been solved using micro-crystallographic techniques that previously could not have been solved with conventional crystallography. At GM/CA-CAT we continue to develop micro-crystallographic capabilities for difficult problems such as small crystals of large macromolecular complexes or membrane proteins grown in the lipidic cubic phase. This paper will describe three major upgrades to our arsenal of tools, "mini-beam" collimators, active beamstop, and an improved goniostat. Our "mini-beam" collimators have evolved to a new triple-collimator fabricated from molybdenum as a uni-body. This has significantly improved the robustness, ease of initial alignment, and reduction of background. More recently, two prototypes of a quad-collimator have been developed and fabricated to provide a selection of mini-beams of 5, 10, 20 mu m and a 300 mu m scatter-guard on a single body. The smaller beams and samples have increased the demand on the tolerances of our goniostat. To meet these challenges we have designed and implemented a goniostat with a 1-micron peak-to-peak sphere of confusion. This is a significant improvement over the previous 6 micron sphere of confusion of the commercially available air-bearing and XY stages. Finally, an "active beamstop" has been constructed. This will provide non-invasive, real time feedback at the sample during data collection.

AB Among the possibilities for a next-generation hard x-ray source is a so-called "ultimate storage ring." This refers to a large, high-energy storage ring with very low emittance and high current. Such a ring has the potential to deliver significantly higher spectral brightness and transverse coherence than present third-generation rings. At the same time, it promises the stability and reliability that users have come to expect in a light source. In this paper, we present a design for a 7-GeV, 40-sector storage ring with a circumference of 3.1 km and an emittance of 15 pm in both planes.

AB Acidaminococcus fermentans (Rogosa 1969) is the type species of the genus Acidaminococcus, and is of phylogenetic interest because of its isolated placement in a genomically little characterized region of the Firmicutes. A. fermentans is known for its habitation of the gastrointestinal tract and its ability to oxidize trans-aconitate. Its anaerobic fermentation of glutamate has been intensively studied and will now be complemented by the genomic basis. The strain described in this report is a nonsporulating, nonmotile, Gram-negative coccus, originally isolated from a pig alimentary tract. Here we describe the features of this organism, together with the complete genome sequence, and annotation. This is the first complete genome sequence of a member of the family Acidaminococcaceae, and the 2,329,769 bp long genome with its 2,101 protein-coding and 81 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Cellulomonas flavigena (Kellerman and McBeth 1912) Bergey et al. 1923 is the type species of the genus Cellulomonas of the actinobacterial family Cellulomonadaceae. Members of the genus Cellulomonas are of special interest for their ability to degrade cellulose and hemicellulose, particularly with regard to the use of biomass as an alternative energy source. Here we describe the features of this organism, together with the complete genome sequence, and annotation. This is the first complete genome sequence of a member of the genus Cellulomonas, and next to the human pathogen Tropheryma whipplei the second complete genome sequence within the family Cellulomonadaceae. The 4,123,179 bp long single replicon genome with its 3,735 protein-coding and 53 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Meiothermus ruber (Loginova et al. 1984) Nobre et al. 1996 is the type species of the genus Meiothermus. This thermophilic genus is of special interest, as its members share relatively low degrees of 16S rRNA gene sequence similarity and constitute a separate evolutionary lineage from members of the genus Thermus, from which they can generally be distinguished by their slightly lower temperature optima. The temperature related split is in accordance with the chemotaxonomic feature of the polar lipids. M. ruber is a representative of the low-temperature group. This is the first completed genome sequence of the genus Meiothermus and only the third genome sequence to be published from a member of the family Thermaceae. The 3,097,457 bp long genome with its 3,052 protein-coding and 53 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Meiothermus silvanus (Tenreiro et al. 1995) Nobre et al. 1996 belongs to a thermophilic genus whose members share relatively low degrees of 16S rRNA gene sequence similarity. Meiothermus constitutes an evolutionary lineage separate from members of the genus Thermus, from which they can generally be distinguished by their slightly lower temperature optima. M. silvanus is of special interest as it causes colored biofilms in the paper making industry and may thus be of economic importance as a biofouler. This is the second completed genome sequence of a member of the genus Meiothermus and only the third genome sequence to be published from a member of the family Thermaceae. The 3,721,669 bp long genome with its 3,667 protein-coding and 55 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Planctomyces limnophilus Hirsch and Muller 1986 belongs to the order Planctomycetales, which differs from other bacterial taxa by several distinctive features such as internal cell compartmentalization, multiplication by forming buds directly from the spherical, ovoid or pear-shaped mother cell and a cell wall which is stabilized by a proteinaceous layer rather than a peptidoglycan layer. Besides Pirellula staleyi, this is the second completed genome sequence of the family Planctomycetaceae. P. limnophilus is of interest because it differs from Pirellula by the presence of a stalk and its structure of fibril bundles, its cell shape and size, the formation of multicellular rosettes, low salt tolerance and red pigmented colonies. The 5,460,085 bp long genome with its 4,304 protein-coding and 66 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Olsenella uli (Olsen et al. 1991) Dewhirst et al. 2001 is the type species of the genus Olsenella, which belongs to the actinobacterial family Coriobacteriaceae. The species is of interest because it is frequently isolated from dental plaque in periodontitis patients and can cause primary endodontic infection. The species is a Gram-positive, non-motile and non-sporulating bacterium. The strain described in this study was isolated from human gingival crevices. This is the first completed sequence of the genus Olsenella and the fifth sequence from a member of the family Coriobacteriaceae. The 2,051,896 bp long genome with its 1,795 protein-coding and 55 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Dethiosulfovibrio peptidovorans Magot et al. 1997 is the type species of the genus Dethiosulfovibrio of the family Synergistaceae in the recently created phylum Synergistetes. The strictly anaerobic, vibriod, thiosulfate-reducing bacterium utilizes peptides and amino acids, but neither sugars nor fatty acids. It was isolated from an offshore oil well where it was been reported to be involved in pitting corrosion of mild steel. Initially, this bacterium was described as a distant relative of the genus Thermoanaerobacter, but was not assigned to a genus, it was subsequently placed into the novel phylum Synergistetes. A large number of repeats in the genome sequence prevented an economically justifiable closure of the last gaps. This is only the third published genome from a member of the phylum Synergistetes. The 2,576,359 bp long genome consists of three contigs with 2,458 protein-coding and 59 RNA genes and is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Arcanobacterium haemolyticum (ex MacLean et al. 1946) Collins et al. 1983 is the type species of the genus Arcanobacterium, which belongs to the family Actinomycetaceae. The strain is of interest because it is an obligate parasite of the pharynx of humans and farm animal; occasionally, it causes pharyngeal or skin lesions. It is a Gram-positive, nonmotile and non-sporulating bacterium. The strain described in this study was isolated from infections amongst American soldiers of certain islands of the North and West Pacific. This is the first completed sequence of a member of the genus Arcanobacterium and the ninth type strain genome from the family Actinomycetaceae.

AB 'Thermobaculum terrenum' Botero et al. 2004 is the sole species within the proposed genus 'Thermobaculum'. Strain YNP1(T) is the only cultivated member of an acid tolerant, extremely thermophilic species belonging to a phylogenetically isolated environmental clone group within the phylum Chloroflexi. At present, the name 'Thermobaculum terrenum' is not yet validly published as it contravenes Rule 30 (3a) of the Bacteriological Code. The bacterium was isolated from a slightly acidic extreme thermal soil in Yellowstone National Park, Wyoming (USA). Depending on its final taxonomic allocation, this is likely to be the third completed genome sequence of a member of the class Thermomicrobia and the seventh type strain genome from the phylum Chloroflexi. The 3,101,581 bp long genome with its 2,872 protein-coding and 58 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB The hydrothermal vent clam Calyptogena magnifica (Bivalvia: Mollusca) is a member of the Vesicomyidae. Species within this family form symbioses with chemosynthetic Gammaproteobacteria. They exist in environments such as hydrothermal vents and cold seeps and have a rudimentary gut and feeding groove, indicating a large dependence on their endosymbionts for nutrition. The C. magnifica symbiont, Candidatus Ruthia magnifica, was the first intracellular sulfur-oxidizing endosymbiont to have its genome sequenced (Newton et al. 2007). Here we expand upon the original report and provide additional details complying with the emerging MIGS/MIMS standards. The complete genome exposed the genetic blueprint of the metabolic capabilities of the symbiont. Genes which were predicted to encode the proteins required for all the metabolic pathways typical of free-living chemoautotrophs were detected in the symbiont genome. These include major pathways including carbon fixation, sulfur oxidation, nitrogen assimilation, as well as amino acid and cofactor/vitamin biosynthesis. This genome sequence is invaluable in the study of these enigmatic associations and provides insights into the origin and evolution of autotrophic endosymbiosis.

AB Both metagenomic data and metatranscriptomic data were collected from surface water (0-2m) of the L4 sampling station (50.2518 N, 4.2089 W), which is part of the Western Channel Observatory long-term coastal-marine monitoring station. We previously generated from this area a six-year time series of 16S rRNA V6 data, which demonstrated robust seasonal structure for the bacterial community, with diversity correlated with day length. Here we describe the features of these metagenomes and metatranscriptomes. We generated 8 metagenomes (4.5 million sequences, 1.9 Gbp, average read-length 350 bp) and 7 metatranscriptomes (392,632 putative mRNA-derived sequences, 159 Mbp, average read-length 272 bp) for eight time-points sampled in 2008. These time points represent three seasons (winter, spring, and summer) and include both day and night samples. These data demonstrate the major differences between genetic potential and actuality, whereby genomes follow general seasonal trends yet with surprisingly little change in the functional potential over time; transcripts tended to be far more structured by changes occurring between day and night.

AB Sulfurimonas autotrophica Inagaki et al. 2003 is the type species of the genus Sulfurimonas. This genus is of interest because of its significant contribution to the global sulfur cycle as it oxidizes sulfur compounds to sulfate and by its apparent habitation of deep-sea hydrothermal and marine sulfidic environments as potential ecological niche. Here we describe the features of this organism, together with the complete genome sequence and annotation. This is the second complete genome sequence of the genus Sulfurimonas and the 15(th) genome in the family Helicobacteraceae. The 2,153,198 bp long genome with its 2,165 protein-coding and 55 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Methanoplanus petrolearius Ollivier et al. 1998 is the type strain of the genus Methanoplanus. The strain was originally isolated from an offshore oil field from the Gulf of Guinea. Members of the genus Methanoplanus are of interest because they play an important role in the carbon cycle and also because of their significant contribution to the global warming by methane emission in the atmosphere. Like other archaea of the family Methanomicrobiales, the members of the genus Methanoplanus are able to use CO2 and H-2 as a source of carbon and energy; acetate is required for growth and probably also serves as carbon source. Here we describe the features of this organism, together with the complete genome sequence and annotation. This is the first complete genome sequence of a member of the family Methanomicrobiaceae and the sixth complete genome sequence from the order Methanomicrobiales. The 2,843,290 bp long genome with its 2,824 protein-coding and 57 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Syntrophothermus lipocalidus Sekiguchi et al. 2000 is the type species of the genus Syntrophothermus. The species is of interest because of its strictly anaerobic lifestyle, its participation in the primary step of the degradation of organic maters, and for releasing products which serve as substrates for other microorganisms. It also contributes significantly to maintain a regular pH in its environment by removing the fatty acids through beta-oxidation. The strain is able to metabolize isobutyrate and butyrate, which are the substrate and the product of degradation of the substrate, respectively. This is the first complete genome sequence of a member of the genus Syntrophothermus and the second in the family Syntrophomonadaceae. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 2,405,559 bp long genome with its 2,385 protein-coding and 55 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Desulfarculus baarsii (Widdel 1981) Kuever et al. 2006 is the type and only species of the genus Desulfarculus, which represents the family Desulfarculaceae and the order Desulfarculales. This species is a mesophilic sulfate-reducing bacterium with the capability to oxidize acetate and fatty acids of up to 18 carbon atoms completely to CO2. The acetyl-CoA/CODH (Wood-Ljungdahl) pathway is used by this species for the complete oxidation of carbon sources and autotrophic growth on formate. The type strain 2st14(T) was isolated from a ditch sediment collected near the University of Konstanz, Germany. This is the first completed genome sequence of a member of the order Desulfarculales. The 3,655,731 bp long single replicon genome with its 3,303 protein-coding and 52 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Intrasporangium calvum Kalakoutskii et al. 1967 is the type species of the genus Intrasporangium, which belongs to the actinobacterial family Intrasporangiaceae. The species is a Gram-positive bacterium that forms a branching mycelium, which tends to break into irregular fragments. The mycelium of this strain may bear intercalary vesicles but does not contain spores. The strain described in this study is an airborne organism that was isolated from a school dining room in 1967. One particularly interesting feature of I. calvum is that the type of its menaquinone is different from all other representatives of the family Intrasporangiaceae. This is the first completed genome sequence from a member of the genus Intrasporangium and also the first sequence from the family Intrasporangiaceae. The 4,024,382 bp long genome with its 3,653 protein-coding and 57 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

The species is of interest because its members are able to ferment quite a number of sugars and organic acids. I. polytropus has a broad versatility in using various fermentation pathways. Also, its members do not degrade poly-beta-hydroxybutyrate but only the monomeric 3-hydroxybutyrate. This is the first completed genome sequence of a member of the genus Ilyobacter and the second sequence from the family Fusobacteriaceae.

AB Methanothermus fervidus Stetter 1982 is the type strain of the genus Methanothermus. This hyperthermophilic genus is of a thought to be endemic in Icelandic hot springs. M. fervidus was not only the first characterized organism with a maximal growth temperature ( 97 degrees C) close to the boiling point of water, but also the first archaeon in which a detailed functional analysis of its histone protein was reported and the first one in which the function of 2,3-cyclodiphosphoglycerate in thermoadaptation was characterized. Strain V24S(T) is of interest because of its very low substrate ranges, it grows only on H-2 + CO2. This is the first completed genome sequence of the family Methanothermaceae. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 1,243,342 bp long genome with its 1,311 protein-coding and 50 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Nocardiopsis dassonvillei (Brocq-Rousseau 1904) Meyer 1976 is the type species of the genus Nocardiopsis, which in turn is the type genus of the family Nocardiopsaceae. This species is of interest because of its ecological versatility. Members of N. dassonvillei have been isolated from a large variety of natural habitats such as soil and marine sediments, from different plant and animal materials as well as from human patients. Moreover, representatives of the genus Nocardiopsis participate actively in biopolymer degradation. This is the first complete genome sequence in the family Nocardiopsaceae. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 6,543,312 bp long genome consist of a 5.77 Mbp chromosome and a 0.78 Mbp plasmid and with its 5,570 protein-coding and 77 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Thermaerobacter marianensis Takai et al. 1999 is the type species of the genus Thermaerobacter, which belongs to the Clostridiales family Incertae Sedis XVII. The species is of special interest because T. marianensis is an aerobic, thermophilic marine bacterium, originally isolated from the deepest part in the western Pacific Ocean (Mariana Trench) at the depth of 10, 897 m. Interestingly, the taxonomic status of the genus has not been clarified until now. The genus Thermaerobacter may represent a very deep group within the Firmicutes or potentially a novel phylum. The 2,844,696 bp long genome with its 2,375 protein-coding and 60 RNA genes consists of one circular chromosome and is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Alicyclobacillus acidocaldarius (Darland and Brock 1971) is the type species of the larger of the two genera in the bacillal family 'Alicyclobacillaceae'. A. acidocaldarius is a free-living and non-pathogenic organism, but may also be associated with food and fruit spoilage. Due to its acidophilic nature, several enzymes from this species have since long been subjected to detailed molecular and biochemical studies. Here we describe the features of this organism, together with the complete genome sequence and annotation. This is the first completed genome sequence of the family 'Alicyclobacillaceae'. The 3,205,686 bp long genome (chromosome and three plasmids) with its 3,153 protein-coding and 82 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Desulfohalobium retbaense (Ollivier et al. 1991) is the type species of the polyphyletic genus Desulfohalobium, which comprises, at the time of writing, two species and represents the family Desulfohalobiaceae within the Deltaproteobacteria. D. retbaense is a moderately halophilic sulfate-reducing bacterium, which can utilize H-2 and a limited range of organic substrates, which are incompletely oxidized to acetate and CO2, for growth. The type strain HR100T was isolated from sediments of the hypersaline Retba Lake in Senegal. Here we describe the features of this organism, together with the complete genome sequence and annotation. This is the first completed genome sequence of a member of the family Desulfohalobiaceae.

AB Sphaerobacter thermophilus Demharter et al. 1989 is the sole and type species of the genus Sphaerobacter, which is the type genus of the family Sphaerobacteraceae, the order Sphaerobacterales and the subclass Sphaerobacteridae. Phylogenetically, it belongs to the genomically little studied class of the Thermomicrobia in the bacterial phylum Chloroflexi. Here, the genome of strain S 6022(T) is described which is an obligate aerobe that was originally isolated from an aerated laboratory-scale fermentor that was pulse fed with municipal sewage sludge. We describe the features of this organism, together with the complete genome and annotation. This is the first complete genome sequence of the thermomicrobial subclass Sphaerobacteridae, and the second sequence from the chloroflexal class Thermomicrobia. The 3,993,764 bp genome with its 3,525 protein-coding and 57 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Veillonella parvula (Veillon and Zuber 1898) Prevot 1933 is the type species of the genus Veillonella in the family Veillonellaceae within the order Clostridiales. The species V. parvula is of interest because it is frequently isolated from dental plaque in the human oral cavity and can cause opportunistic infections. The species is strictly anaerobic and grows as small cocci which usually occur in pairs. Veillonellae are characterized by their unusual metabolism which is centered on the activity of the enzyme methylmalonyl-CoA decarboxylase. Strain Te3(T), the type strain of the species, was isolated from the human intestinal tract. Here we describe the features of this organism, together with the complete genome sequence, and annotation. This is the first complete genome sequence of a member of the large clostridial family Veillonellaceae, and the 2,132,142 bp long single replicon genome with its 1,859 protein-coding and 61 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Rhizobium leguminosarum bv trifolii is the effective nitrogen fixing microsymbiont of a diverse range of annual and perennial Trifolium (clover) species. Strain WSM2304 is an aerobic, motile, non-spore forming, Gram-negative rod, isolated from Trifolium polymorphum in Uruguay in 1998. This microsymbiont predominated in the perennial grasslands of Glencoe Research Station, in Uruguay, to competitively nodulate its host, and fix atmospheric nitrogen. Here we describe the basic features of WSM2304, together with the complete genome sequence, and annotation. This is the first completed genome sequence for a nitrogen fixing microsymbiont of a clover species from the American center of origin. We reveal that its genome size is 6,872,702 bp encoding 6,643 protein-coding genes and 62 RNA only encoding genes. This multipartite genome was found to contain 5 distinct replicons; a chromosome of size 4,537,948 bp and four circular plasmids of size 1,266,105 bp, 501,946 bp, 308,747 bp and 257,956 bp.

AB Ensifer (Sinorhizobium) medicae is an effective nitrogen fixing microsymbiont of a diverse range of annual Medicago (medic) species. Strain WSM419 is an aerobic, motile, non-spore forming, Gram-negative rod isolated from a M. murex root nodule collected in Sardinia, Italy in 1981. WSM419 was manufactured commercially in Australia as an inoculant for annual medics during 1985 to 1993 due to its nitrogen fixation, saprophytic competence and acid tolerance properties. Here we describe the basic features of this organism, together with the complete genome sequence, and annotation. This is the first report of a complete genome sequence for a microsymbiont of the group of annual medic species adapted to acid soils. We reveal that its genome size is 6,817,576 bp encoding 6,518 protein-coding genes and 81 RNA only encoding genes. The genome contains a chromosome of size 3,781,904 bp and 3 plasmids of size 1,570,951 bp, 1,245,408 bp and 219,313 bp. The smallest plasmid is a feature unique to this medic microsymbiont.

AB Haliangium ochraceum Fudou et al. 2002 is the type species of the genus Haliangium in the myxococcal family 'Haliangiaceae'. Members of the genus Haliangium are the first halophilic myxobacterial taxa described. The cells of the species follow a multicellular lifestyle in highly organized biofilms, called swarms, they decompose bacterial and yeast cells as most myxobacteria do. The fruiting bodies contain particularly small coccoid myxospores. H. ochraceum encodes the first actin homologue identified in a bacterial genome. Here we describe the features of this organism, together with the complete genome sequence, and annotation. This is the first complete genome sequence of a member of the myxococcal suborder Nannocystineae, and the 9,446,314 bp long single replicon genome with its 6,898 protein-coding and 53 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Haloterrigena turkmenica (Zvyagintseva and Tarasov 1987) Ventosa et al. 1999, comb. nov. is the type species of the genus Haloterrigena in the euryarchaeal family Halobacteriaceae. It is of phylogenetic interest because of the yet unclear position of the genera Haloterrigena and Natrinema within the Halobacteriaceae, which created some taxonomic problems historically. H. turkmenica, was isolated from sulfate saline soil in Turkmenistan, is a relatively fast growing, chemoorganotrophic, carotenoid-containing, extreme halophile, requiring at least 2 M NaCl for growth. Here we describe the features of this organism, together with the complete genome sequence, and annotation. This is the first complete genome sequence of the genus Haloterrigena, but the eighth genome sequence from a member of the family Halobacteriaceae. The 5,440,782 bp genome (including six plasmids) with its 5,287 protein-coding and 63 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB The genus Kribbella consists of 15 species, with Kribbella flavida (Park et al. 1999) as the type species. The name Kribbella was formed from the acronym of the Korea Research Institute of Bioscience and Biotechnology, KRIBB. Strains of the various Kribbella species were originally isolated from soil, potato, alum slate mine, patinas of catacombs or from horse racecourses. Here we describe the features of K. flavida together with the complete genome sequence and annotation. In addition to the 5.3 Mbp genome of Nocardioides sp. JS614, this is only the second completed genome sequence of the family Nocardioidaceae. The 7,579,488 bp long genome with its 7,086 protein-coding and 60 RNA genes and is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Thermocrinis albus Eder and Huber 2002 is one of three species in the genus Thermocrinis in the family Aquificaceae. Members of this family have become of significant interest because of their involvement in global biogeochemical cycles in high-temperature ecosystems. This interest had already spurred several genome sequencing projects for members of the family. We here report the first completed genome sequence a member of the genus Thermocrinis and the first type strain genome from a member of the family Aquificaceae. The 1,500,577 bp long genome with its 1,603 protein-coding and 47 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Segniliparus rotundus Butler 2005 is the type species of the genus Segniliparus, which is currently the only genus in the corynebacterial family Segniliparaceae. This family is of large interest because of a novel late-emerging genus-specific mycolate pattern. The type strain has been isolated from human sputum and is probably an opportunistic pathogen. Here we describe the features of this organism, together with the complete genome sequence and annotation. This is the first completed genome sequence of the family Segniliparaceae. The 3,157,527 bp long genome with its 3,081 protein-coding and 52 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB The genus Conexibacter (Monciardini et al. 2003) represents the type genus of the family Conexibacteraceae (Stackebrandt 2005, emend. Zhi et al. 2009) with Conexibacter woesei as the type species of the genus. C. woesei is a representative of a deep evolutionary line of descent within the class Actinobacteria. Strain ID131577(T) was originally isolated from temperate forest soil in Gerenzano (Italy). Cells are small, short rods that are motile by peritrichous flagella. They may form aggregates after a longer period of growth and, then as a typical characteristic, an undulate structure is formed by self-aggregation of flagella with entangled bacterial cells. Here we describe the features of the organism, together with the complete sequence and annotation. The 6,359,369 bp long genome of C. woesei contains 5,950 protein-coding and 48 RNA genes and is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Sebaldella termitidis (Sebald 1962) Collins and Shah 1986, is the only species in the genus Sebaldella within the fusobacterial family 'Leptotrichiaceae'. The sole and type strain of the species was first isolated about 50 years ago from intestinal content of Mediterranean termites. The species is of interest for its very isolated phylogenetic position within the phylum Fusobacteria in the tree of life, with no other species sharing more than 90% 16S rRNA sequence similarity. The 4,486,650 bp long genome with its 4,210 protein-coding and 54 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Brachyspira murdochii Stanton et al. 1992 is a non-pathogenic host-associated spirochete of the family Brachyspiraceae. Initially isolated from the intestinal content of a healthy swine, the 'group B spirochaetes' were first described under as Serpulina murdochii. Members of the family Brachyspiraceae are of great phylogenetic interest because of the extremely isolated location of this family within the phylum 'Spirochaetes'. Here we describe the features of this organism, together with the complete genome sequence and annotation. This is the first completed genome sequence of a type strain of a member of the family Brachyspiraceae and only the second genome sequence from a member of the genus Brachyspira. The 3,241,804 bp long genome with its 2,893 protein-coding and 40 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Denitrovibrio acetiphilus Myhr and Torsvik 2000 is the type species of the genus Denitrovibrio in the bacterial family Deferribacteraceae. It is of phylogenetic interest because there are only six genera described in the family Deferribacteraceae. D. acetiphilus was isolated as a representative of a population reducing nitrate to ammonia in a laboratory column simulating the conditions in off-shore oil recovery fields. When nitrate was added to this column undesirable hydrogen sulfide production was stopped because the sulfate reducing populations were superseded by these nitrate reducing bacteria. Here we describe the features of this marine, mesophilic, obligately anaerobic organism respiring by nitrate reduction, together with the complete genome sequence, and annotation. This is the second complete genome sequence of the order Deferribacterales and the class Deferribacteres, which is the sole class in the phylum Deferribacteres. The 3,222,077 bp genome with its 3,034 protein-coding and 51 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Arcobacter nitrofigilis (McClung et al. 1983) Vandamme et al. 1991 is the type species of the genus Arcobacter in the family Campylobacteraceae within the Epsilonproteobacteria. The species was first described in 1983 as Campylobacter nitrofigilis [1] after its detection as a free-living, nitrogen-fixing Campylobacter species associated with Spartina alterniflora Loisel roots [2]. It is of phylogenetic interest because of its lifestyle as a symbiotic organism in a marine environment in contrast to many other Arcobacter species which are associated with warm-blooded animals and tend to be pathogenic. Here we describe the features of this organism, together with the complete genome sequence, and annotation. This is the first complete genome sequence of a type stain of the genus Arcobacter.

AB Thermobispora bispora (Henssen 1957) Wang et al. 1996 is the type species of the genus Thermobispora. This genus is of great interest because it is strictly thermophilic and because it has been shown for several of its members that the genome contains substantially distinct (6.4% sequence difference) and transcriptionally active 16S rRNA genes. Here we describe the features of this organism, together with the complete genome sequence and annotation.

AB Archaeoglobus profundus (Burggraf et al. 1990) is a hyperthermophilic archaeon in the euryarchaeal class Archaeoglobi, which is currently represented by the single family Archaeoglobaceae, containing six validly named species and two strains ascribed to the genus 'Geoglobus' which is taxonomically challenged as the corresponding type species has no validly published name. All members were isolated from marine hydrothermal habitats and are obligate anaerobes. Here we describe the features of the organism, together with the complete genome sequence and annotation. This is the second completed genome sequence of a member of the class Archaeoglobi. The 1,563,423 bp genome with its 1,858 protein-coding and 52 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

AB Rhizobium leguminosarum bv trifolii is a soil-inhabiting bacterium that has the capacity to be an effective nitrogen fixing microsymbiont of a diverse range of annual Trifolium (clover) species. Strain WSM1325 is an aerobic, motile, non-spore forming, Gram-negative rod isolated from root nodules collected in 1993 from the Greek Island of Serifos. WSM1325 is produced commercially in Australia as an inoculant for a broad range of annual clovers of Mediterranean origin due to its superior attributes of saprophytic competence, nitrogen fixation and acid-tolerance. Here we describe the basic features of this organism, together with the complete genome sequence, and annotation. This is the first completed genome sequence for a microsymbiont of annual clovers. We reveal that its genome size is 7,418,122 bp encoding 7,232 protein-coding genes and 61 RNA-only encoding genes. This multipartite genome contains 6 distinct replicons; a chromosome of size 4,767,043 bp and 5 plasmids of size 828,924 bp, 660,973 bp, 516,088 bp, 350,312 bp and 294,782 bp.

DT Article

ID NORMALIZATION METHODS; MICROARRAY DATA; QUALITY-CONTROL; VALIDATION
AB Nuisance factors in a protein-array study add obfuscating variation to spot intensity measurements, diminishing the accuracy and precision of protein concentration predictions. The effects of nuisance factors may be reduced by design of experiments, and by estimating and then subtracting nuisance effects. Estimated nuisance effects also inform about the quality of the study and suggest refinements for future studies.
We demonstrate a method to reduce nuisance effects by incorporating a non-interfering internal calibration in the study design and its complemental analysis of variance. We illustrate this method by applying a chip-level internal calibration in a biomarker discovery study.
The variability of sample intensity estimates was reduced 16% to 92% with a median of 58%; confidence interval widths were reduced 8% to 70% with a median of 35%. Calibration diagnostics revealed processing nuisance trends potentially related to spot print order and chip location on a slide.
The accuracy and precision of a protein-array study may be increased by incorporating a non-interfering internal calibration. Internal calibration modeling diagnostics improve confidence in study results and suggest process steps that may need refinement. Though developed for our protein-array studies, this internal calibration method is applicable to other targeted array-based studies.

TI Sequential Design of Computer Experiments for Constrained Optimization
SO STATISTICAL MODELLING AND REGRESSION STRUCTURES: FESTSCHRIFT IN HONOUR
OF LUDWIG FAHRMEIR
LA English
DT Article; Book Chapter
ID PREDICTION
AB This paper proposes a sequential method of designing computer or physical experiments when the goal is to optimize one integrated signal function subject to constraints on the integral of a second response function. Such problems occur, for example, in industrial problems where the computed responses depend on two types of inputs: manufacturing variables and noise variables. In industrial settings, manufacturing variables are determined by the product designer; noise variables represent field conditions which are modeled by specifying a probability distribution for these variables. The update scheme of the proposed method selects the control portion of the next input site to maximize a posterior expected "improvement" and the environmental portion of this next input is selected to minimize the mean square prediction error of the objective function at the new control site. The method allows for dependence between the objective and constraint functions. The efficacy of the algorithm relative to the single-stage design and relative to a design assuming independent responses is illustrated. Implementation issues for the deterministic and measurement error cases are discussed as are some generalizations of the method.

AB Marginal (contingency) tables are the method of choice for government agencies releasing statistical summaries of categorical data. In this paper, we derive lower bounds on how much distortion (noise) is necessary in these tables to ensure the privacy of sensitive data. We extend a line of recent work on impossibility results for private data analysis [9, 12, 13, 15] to a natural and important class of functionalities.
Consider a database consisting of n rows (one per individual), each row comprising d binary attributes. For any subset of T attributes of size vertical bar T vertical bar = k, the marginal table for T has 2(k) entries; each entry counts how many times in the database a particular setting of these attributes occurs. We provide lower bounds for releasing all ((d)(k)) k-attribute marginal tables under several different notions of privacy.
(1) We give efficient polynomial time attacks which allow an adversary to reconstruct sensitive information given insufficiently :perturbed marginal table releases. In particular, for a constant k, we obtain a tight bound of (Omega) over tilde (min{root n, root d(k-1)})(1) on the average distortion per entry for any mechanism that releases all k-attribute marginals while providing "attribute" :privacy (a weak notion implied by most privacy definitions).
(2) Our reconstruction attacks require a new lower bound on the least singular value of a random matrix with correlated rows. Let M-(k) be a matrix with ((d)(k)) rows formed by taking all possible k-way entry-wise products of an underlying set of d random vectors from {0, 1}(n). For constant k, we show that the least singular value of M-(k) is (Omega) over tilde(root d(k)) with high probability (the same asymptotic bound as for independent rows).
(3) We obtain stronger lower bounds for marginal tables satisfying differential privacy. We give a lower bound of (Omega) over tilde (min{root n, root d(k)}), which is tight for n = (Omega) over tilde (d(k)). We extend our analysis to obtain stronger results for mechanisms that add instance-independent noise and weaker results when k is super-constant.

AB We review recent progress in our understanding of the role of strange quarks in the structure of the nucleon. For the contribution to its mass the result is remarkably small, an order of magnitude smaller than commonly assumed. This has profound consequences for the searches for dark matter which are currently underway. There has also been remarkable progress in the understanding of hypernuclei. In particular, there is a very natural explanation at the quark level of why Lambda-hypernuclei are bound whereas Sigma-hypernuclei are not. The consequences for dense matter, for example in neutron stars, are not yet fully understood but we know they are significant.

DE Cascade resonances; hyperon photoproduction; cascade pentaquarks
AB We present the results of photoproduction cross sections of the ground state cascade Xi(-) and the first excited state Xi*(-) (1530) measured with the CLAS detector. The photoproduction of the cascade resonances has been investigated in the reactions gamma p -> K+K+(X) and gamma p -> K+K+pi(-)(X). The differential and total cross sections of the E were determined for photon beam energies from 2.75 to 4.75 GeV and are consistent with a production mechanism of Y* -> K+ Xi(-) through a t-channel process. The cross-section of the Xi*(-) (1530) has been determined for photon beam energies from 3.35 to 4.75 GeV. The reaction gamma p -> K+K+pi(-)(Xi(0)) has also been investigated in the search for excited cascade resonances decaying to pi(-)Xi(0). No significant signal of excited cascade states other than the well-known Xi*(-) (1530) is observed. We also present the latest results of a search for the (Phi)(--) (1862) exotic pentaquark state in a photoproduction experiment on a deuterium target. A high-statistics sample of pi(-)Xi(-) events have been collected and analyzed. A preliminary invariant mass spectrum of the pi(-)Xi(-) system is presented, which is used to set upper limits on the photoproduction of the Phi(--) pentaquark state.

DE Lattice QCD calculations; hyperon-nucleon interactions
ID SCATTERING
AB We study p Xi(0) and p Lambda forces by using quenched lattice QCD. The Bethe-Salpeter amplitude is calculated for the lowest scattering state of the systems. The numerical calculation is twofold: (i) For the p Xi(0), the potentials and scattering lengths are obtained by using 32(3) x 32 lattice with beta = 5.7, the lattice spacing of a = 0.1416(9) fm, and two kinds of ud quark mass corresponding to m(pi) similar or equal to 0.37 GeV and 0.51 GeV. The present results indicate that the p Xi(0) interactions are both attractive at S-1(0) and S-3(1) channels, and the interaction in the S-3(1) is more attractive than in the S-1(0). These attractive forces become stronger as the u, d quark mass decreases. (ii) For the p Lambda, the potentials are calculated by using the 32(3) x 48 lattice, and two kinds of ud quark mass corresponding to m pi similar or equal to 0.47 GeV and 0.51 GeV. The present preliminary result shows that the p Lambda interactions are both attractive at S-1(0) and S-3(1) channels.

ID ELECTROMAGNETIC PRODUCTION; JEFFERSON-LAB; STRANGENESS
AB The characteristics of the Jefferson LAB electron beam, together with those of the experimental equipments, offer a unique opportunity to study hypernuclear spectroscopy via electromagnetic induced reactions. Experiment 94-107 started a systematic study on 1p-shell targets, C-12, Be-9 and O-16. We present the results from C-12, O-16 and very preliminary results from Be-9. For C-12 for the first time measurable strength in the core-excited part of the spectrum between the ground state and the p(Lambda) state was shown in B-12(Lambda) for the first time. A high-quality N-16(Lambda) spectrum was produced for the first time with sub-MeV Energy resolution. A very precise B-Lambda value for N-16(Lambda), calibrated against the elementary (e,e'K+) reaction on hydrogen, has also been obtained. Final data on Be-9 will be available soon. The missing energy resolution is the best ever obtained in hypernuclear production experiments.

AB Geologists create volcanic hazard maps using scientific data to portray potential future geological events; the end users are principally public safety officials. Typical maps use a few simple polygons to outline areas of potential inundation or cover by a few categories of flows based on past frequency and size. Uncertainties in data regarding flow characteristics complicate the construction of accurate hazard maps. Generally, there are inadequate exposures of good sections, poorly known extents of units, and imprecise volumes for deposits. Crisis conditions limit the time available for field and laboratory work. Computer models can simulate possible scenarios, but the volumes, styles of emplacement, and source starting locations are poorly known in many cases. The large uncertainty in initial conditions is seldom taken into account in the construction of hazard maps, and these uncertainties are rarely passed on to the end users of the maps. TITAN2D is a computational model for volcanic block-and-ash flows and rock avalanches of various types and scales, and it forms the core of the TITAN toolkit for volcanic hazard analysis, which can integrate high-performance computing, database management, and visualization to a very sophisticated level. TITAN provides a solution to mapping problems by providing a probabilistic calculation of inundation depth that takes into account many of the critical uncertainties.

AB This paper is a report of an initial investigation into tracking and monitoring the integrity of bolted joints using piezoelectric active-sensors. The target application of this study is a fitting lug assembly of unmanned aerial vehicles (UAVs), where a composite wing is mounted to UAV fuselage. The SHM methods deployed in this study are impedance-based SHM techniques, time-series analysis, and high-frequency response functions measured by piezoelectric active-sensors. Different types of simulated damage are introduced into the structure, and the capability of each technique is examined and compared. Additional considerations encountered in this initial investigation are made to guide further thorough research required for the successful field deployment of this technology.

AB This paper presents a variety of structural health monitoring (SHM) techniques, based on the use of piezoelectric active-sensors, used to determine the structural integrity of wind turbine blades, Specifically, Lamp wave propagations, frequency response functions, and time series based methods are utilized to estimate the condition of wind turbine blades. For experiments, a 1m section of a 9m CX100 blade is used. Overall, these three methods yielded a sufficient damage detection capability to warrant further investigation into field deployment. A full-scale fatigue test of a CX-100 wind turbine blade is also conducted. This paper summarizes considerations needed to design such SHM systems, experimental procedures and results, and practical implementation issues that can be used as guidelines for future investigations.

AB The basic purpose of the paper is simple; having proposed a set of axioms or 'basic truths' regarding Structural Health Monitoring (SHM) in a previous paper, the authors would like to extend the set by the proposal for a new axiom. This axiom relates to an observation that the presence of damage in a structure or system usually results in increased complexity of measured responses or features. It is argued that this observation could lead to principled means of selecting effective features for SHM.

AB Systematic effects of Zr additions on the structural and flux pinning properties of YBa(2)Cu(3)O(7-delta) (YBCO) films deposited by metal-organic chemical vapor deposition (MOCVD) have been investigated. Detailed characterization, conducted by coordinated transport, x-ray diffraction, scanning and transmission electron microscopy analyses, and imaging Raman microscopy have revealed trends in the resulting property/performance correlations of these films with respect to varying mole percentages (mol%) of added Zr. For compositions <= 7.5 mol%, Zr additions lead to improved in-field critical current density, as well as extra correlated pinning along the c-axis direction of the YBCO films via the formation of columnar, self-assembled stacks of BaZrO(3) nanodots.

AB Metal-organic chemical vapor deposited YBa2Cu3O6+delta (YBCO) films (about 0.9 mu m thick) containing varying amounts of added zirconium were examined by Raman microscopy and synchrotron x-ray absorption spectroscopy. The self-field and in-field (1 T, B parallel to c) J(c) performance of the YBCO films at 77 K (reported by the group at Oak Ridge National Laboratory that fabricated the samples) exhibited an increase on going from 0 mol% (m/o) Zr-added to 2.5 m/o Zr-added but then decreased sharply with increasing Zr content. Raman measurements on these films showed that the added Zr had little effect on YBCO cation disorder up to about 7.5 m/o Zr-added. Cation disorder increased while Ba-Cu-O content remained relatively constant for Zr additions >= 7.5 m/o. In the region of sharpest descent of J(c) with increasing Zr content (2.5-7.5 m/o Zr-added) neither the cation disorder nor the Ba-Cu-O content showed a systematic variation with J(c). Zirconium K edge x-ray absorption near-edge spectroscopy revealed that virtually all of the added Zr in each sample was present as a BaZrO3-like phase (BZO). The J(c) performance of the Zr-added films showed a high correlation with the variations in the next-nearest-neighbor Zr-M (M = Zr, Y) scattering path amplitude from the extended x-ray absorption fine structure (EXAFS) and the critical temperature over the full range of Zr additions and with cation disorder at the higher Zr- added levels (>7.5 m/o). There was no obvious correlation with the amount of residual barium cuprate or CuO. Approximate ranges for the BZO particle dimensions estimated from the EXAFS data indicated that the mean particle size gets larger with increasing Zr addition.

AB We demonstrate coated conductors fabricated by reactive co-evaporation of YBa(2)Cu(3)O(y) (YBCO) by cyclic deposition and reaction (RCE-CDR) on ion-beam-assisted-deposition-(IBAD-) textured templates simplified by the elimination of the epitaxial buffer layer. Hastelloy substrates, both polished and unpolished, were used as a starting material for the IBAD templates. Y(2)O(3) bed layers were then deposited followed by IBAD- textured MgO and a thin homoepitaxial MgO layer. The MgO-terminated templates were used for direct deposition of YBCO by RCE-CDR. Critical current densities obtained for the undoped YBCO material are comparable to the best values measured previously with the use of LaMnO(3) or SrTiO(3) epitaxial buffer layers and state-of-the-art coated conductor results. The structural characterization data indicate a well oriented YBCO film with a robust template. Electrical measurements also indicate no weak links and a typical magnetic field behavior of undoped YBCO, characterized by a low density of naturally occurring strong pinning centers and correlations along the ab direction.

AB The influence of Zr doping in (Gd, Y)-Ba-Cu-O ((Gd, Y)BCO) tapes made by metal-organic chemical vapor deposition has been studied with a specific objective of uniform and reproducible enhancement in in-field critical current (I(c)) over long lengths. 50 m long tapes with 7.5 and 10 at.% Zr doping in 1 mu m thick (Gd, Y) BCO films have been found to exhibit a sharply enhanced peak in I(c) in the orientation of field parallel to the c-axis and retain 28% of their self-field I(c) value at 77 K and 1 T. BaZrO(3) (BZO) nanocolumn density in the cross-sectional microstructure was found to increase with increasing Zr addition. The end segments of the 50 m long tapes were found to display nearly identical angular dependence of critical current at 77 K and 1 T, indicative of the uniformity in in-field performance over this length. A 610 m long tape was fabricated with 10% Zr doping and a 130 m segment showed a 3.2% uniformity in critical current measured every meter in the orientation of B parallel to c-axis. A retention factor of 36% of the zero-field I(c) value measured at 0.52 T over the 130 m is consistent with that obtained in short samples.

AB The purpose of this study is to enhance properties of the second-generation wires by increasing the density of Y1Ba2Cu3O7 (YBCO) nucleation centers on the surface of the ceria buffer. To identify the nature of the nucleation centers, we compare nucleation kinetics and performance of YBCO layers deposited by the metal-organic process on a standard RABiTS tape to YBCO on ceria buffers with well-controlled structure and surface morphology. The structure of the YBCO layer at the early stage of nucleation and growth is determined by high-flux synchrotron x-ray diffraction. It is shown that the best buffers exhibit high YBCO nucleation rates and produce YBCO nuclei with the least cation disorder. The high YBCO nucleation rate is associated with a high density of threading dislocation outcrops. A strategy for buffer optimization is identified.

AB We have used an ion beam sputtered Y2O3-Al2O3 (YALO) composite to simplify the architecture of high temperature superconducting (HTS) coated conductors (CCs) based on a IBAD MgO template. By implementing YALO, we have reduced the total non-superconducting layers between the polycrystalline metal substrate and the superconducting film from five ( the standard architecture) to four. Well textured (Y, Gd)Ba2Cu3O7-x ((Y, Gd)BCO) films have been successfully grown by MOCVD on this simplified template. The microstructural characterization revealed that all layers are continuous and uniform with sharp and clean interfaces. Additionally, the YALO maintained its amorphous nature after the deposition of the superconductive layer, which is a plus in terms of its efficiency as a diffusion barrier. The achievement of a self-field critical current of 230 A cm(-1) at 75.5 K is another proof of the effectiveness of YALO as a diffusion barrier and nucleation seed for the MgO. The transport properties under an applied magnetic field of MOCVD grown (Y, Gd) BCO on LMO buffered MgO/YALO/Ni-alloy are comparable with those of (Y, Gd) BCO on a standard architecture, thus demonstrating good compatibility between the simplified template with the MOCVD grown (Y, Gd)BCO. The use of a single composite YALO layer instead of individual layers of Y2O3 and Al2O3 for the large scale fabrication of HTS CCs based on IBAD MgO provides advantages such as potentially reduced cost due to the reduced number of fabrication steps.

AB Applications of coated conductors based on high-T-c superconductors often require detailed knowledge of their critical current density J(c) as a function of magnetic field orientation as well as field strength and temperature. This work demonstrates experimental methods for obtaining the angularly dependent J(c) using contact-free magnetic measurements, and qualifies those methods using several well defined conditions. The studies complement traditional transport techniques and are readily extended to conditions of field and temperature where the current density is very large and transport methods become difficult. Results on representative materials are presented.

ID SELF-ASSEMBLED NANODOTS; YBA2CU3O7-DELTA FILMS; PERFORMANCE
AB Phase separated, epitaxial, nanostructured film comprised of BaTiO3 (BTO) and CoFe2O4 (CFO) composite has been developed as a potential multifunctional cap buffer layer for improved flux-pinning in YBa2Cu3O7-delta (YBCO) films. All films were deposited by pulsed laser deposition on SrTiO3 (STO) (100) single crystal substrates. The CFO fraction and growth temperature were identified as key factors for determining the areal number density and mean diameter of the CFO nanocolumns. Compared to the reference sample grown on a pure BTO cap layer, the YBCO films grown on BTO + CFO cap layers show a remarkable improvement in isotropic flux-pinning and, consequently, J(c) over the entire field and angle ranges. Transmission electron microscopy analysis confirmed the presence of a very defective YBCO layer containing a high density of randomly distributed defects at the interface area, induced by nanostructural modulation on the surface of the BTO + CFO composite cap layer.

AB In friction stir welding (FSW), the semi-circular shaped FSW pin tool feed marks that are left behind varied in depth and shape which are detrimental not only in fatigue performance but also in further processing such as superplastic forming (SPF). Experimental investigation was conducted to determine the effects of changes to the FSW process parameters on the surface roughness of the weld of fine grain 2 mm thick titanium alloy, Ti- 6Al-4V. In addition to optimizing the surface texture of the welds, the superplastic performance of the weld nugget was made to be equal to the superplasticity of the parent metal by altering the spindle speed and feed rate used during FSW to identify the quality in terms of cold weld or hot weld. FSW process conditions of spindle speed of 500 RPM and a feed rate of 150 mm/min was found to produce a uniform deformation in both weld and parent metal when the joint was superplastc formed.

AB When certain macrocyclic anion receptors are added to a chloroform solution of the nitrate form of a lipophilic quaternary ammonium salt (methyltri-C8,10-ammonium nitrate, Aliquat 336N), the extraction of sulphate from an aqueous sodium nitrate solution via exchange with the organic-phase nitrate is significantly enhanced. Eight macrocycles were surveyed, including two derivatives of a tetraamide macrocycle, five derivatives of calix[4]pyrrole and -decafluorocalix[5]pyrrole. Under the hypothesis that the enhancement originates from sulphate binding by the anion receptors in the chloroform phase, it was possible to obtain reasonable fits to the sulphate distribution survey data based on the formation of 1:1 and 2:1 receptor:sulphate complexes in the chloroform phase. Apparent 1:1 sulphate-binding constants obtained from the model in this system fell in the range [image omitted]. Comparison of the results for the various anion receptors included in this study reveals that sulphate binding is sensitive to the nature of the substituents on the parent macrocycle scaffolds in a way that does not follow straightforwardly from simple chemical expectations, such as electron-withdrawing effects on hydrogen-bond donor strength.

DT Article; Book Chapter
AB Recent U.S. national mandates are shilling the country's homeland security policy from one of asset-level critical infrastructure protection (CIP) to all-hazards critical infrastructure resilience, creating the need for a unifying framework for assessing the resilience of critical infrastructure systems and the economies that rely on them. Resilience has been defined and applied in many disciplines; consequently, many disparate approaches exist. We propose a general framework for assessing the resilience of infrastructure and economic systems. The framework consists of three primary components: (I) a definition of resilience that is specific to infrastructure systems; (2) a quantitative model for measuring the resilience of systems to disruptive events through the evaluation of both impacts to system performance and the cost of recovery; and (3) a qualitative method for assessing the system properties that inherently determine system resilience, providing insight and direction for potential improvements in these systems.

AB Lignocellulosic biomass, a major feedstock for renewable biofuels and chemicals, is processed by various thermochemical and/or biochemical means. This multi-step processing often involves reactive transformations limited by heat and mass transport. These limitations are dictated by restrictions including (1) plant anatomy, (2) complex ultra-structure and chemical composition of plant cell walls., (3) process engineering requirements or, (4) a combination of these factors. The plant macro- and micro-structural features impose limitations on chemical and enzyme accessibility to carbohydrate containing polymers (cellulose and hemicellulose) which can limit conversion rates and extents. Multiphase systems containing insoluble substrates, soluble catalysts and, in some cases, gaseous steam can pose additional heat and mass transfer restrictions leading to non-uniform reactions. In this chapter, some of these transport challenges relevant to biochemical conversion are discussed in order to underscore the importance of a fundamental understanding of these processes for development of robust and cost-effective routes to fuels and products from lignocellulosic biomass.

AB The model legume species Medicago truncatula is a potentially useful tool for gene discovery in white clover using translational genomics strategies. A prerequisite to the practical implementation of this approach is a good understanding of the extent of conservation of gene order between the species. Previous studies have demonstrated conservation at the macrosyntenic level, but no published information exists on the extent of conserved microsynteny between these species. In a previously published study, we reported the construction of a BAC library of white clover, the end sequencing of approximately 700 clover BACs, and the comparison of these BAC-end sequences to the M. truncatula genome. We found that 14 paired BAC-ends were shown to have the equivalent pairs of M. truncatula sequence on the same M. truncatula BAC clone or contig sequence within a span of 25-200 Kb, suggesting they represent orthologous regions in the two species. In this follow-up analysis, we have chosen five of these BACs, sequenced them to approximately six-fold coverage, and compared the resulting assembled contigs to their putatively equivalent regions of M. truncatula. Highly conserved gene content and almost complete conservation of gene order and orientation for all five sequences were found, suggesting that translational genomics approaches for gene discovery using Medicago could be successful.

AB The Relativistic Heavy Ion Collider (RHIC) at the Brookhaven National Laboratory in the USA is a variable energy proton-proton and ion-ion collider that is the first accelerator capable of colliding heavy ions. RHIC was designed to do experiments that provide important information about the Standard Model of particle physics, Quantum Chromodynamics (QCD). QCD predicts that in the early part of the Universe just after the Big Bang the world consisted of a Quark Gluon Plasma, a weakly interacting collection of quarks and gluons. At RHIC we can recreate the conditions of the early Universe by colliding heavy ions at 200 GeV. This paper will give a general overview of the physics motivation for studying the QGP, how our experiments are designed to study the QGP, what we have learned over the last 9 years, and what the future holds.

AB An inner product is defined on the space of permutation matrices and the space of matrices dual to the permutation matrices is given. The relationship of permutation matrices to the expansion of matrices of fixed line-sum is discussed. This inner product carries over to the space of linear Young operators, as does the notion of the dual space. Motivation from physics for considering such algebraic structures is also given; in particular, the real, orthogonal, irreducible representations of the symmetric group originating from the matrix Schur functions are given.

AB Although the interactions of soft x-rays and hard x-rays with polymers are fundamentally the same and are characterized by absorption and phase shifts, the relative and absolute strength of these interactions as a function of photon energy has profound practical implications. We delineate the basic physics of x-ray interactions with polymers as expressed in the optical constants of polymeric materials and exemplify the resulting advantages of soft x-rays over hard x-rays for real space and reciprocal space characterization methods in the context of a number of recent and ongoing applications. A perspective on future capabilities and applications will be provided.

AB The use of Resonant Soft X-rays Scattering (RSOXS) for the investigation of block copolymer micelles within a thin homopolymer film is demonstrated in this work. Thin films of polystyrene-block-polyisoprene, PS-b-PI, copolymer within a high molecular weight polystyrene, PS, matrix were coated onto Si3N4 substrates. The formation of copolymer micelles with a polyisoprene core and a polystyrene corona was verified by the RSOXS measurements. The thin film samples are difficult to study with hard x-rays or neutrons, and well-suited to the RSOXS approach having stronger cross-sections. The core radius of the PS-b-PI micelles was estimated from the experimental data and was found to be in good agreement with measurements in the bulk and with that theoretically predicted. Increasing copolymer concentration resulted in an increase in the number density of micelles in the films; however, no ordering of the confined micelles was observed, even at high copolymer concentrations, possibly because of the segregation of significant fraction of the PS-b-PI copolymer chains to the air/polymer and polymer/substrate interfaces. In order to overcome this problem polystyrene-block-poly(methyl methacrylate), PS-b-PMMA, was utilized. A PS-b-PMMA/PS film of high copolymer concentration was spin-coated on a pre-treated Si3N4 substrate and RSOXS revealed the formation of dense micelle assemblies within the PS matrix.

AB Most advanced applications of polymers rely on heterogeneous structures or specific interfacial properties to yield desired performance and functionalities. Rational design and application require that these structures be characterized. Recently, it has been demonstrated that soft x-ray scattering is a unique complementary technique to conventional hard x-ray and neutron scattering and an excellent tool for polymer structure determination with improved chemical sensitivity. Efforts to enhance the capabilities and efficiency of soft x-ray scattering through the use of a CCD detector will be delineated and first results presented. Development of a dedicated setup at beamline 11.0.1.2 of the Advanced Light Source will be described. This set-up has an elliptically polarized undulator as a source, which offers complete polarization control and hence unique capabilities.

AB Learning is a task that generalizes many of the analyses that are applied to collections of data, and in particular, collections of sensitive individual information. Hence, it is natural to ask what can be learned while preserving individual privacy. [Kasiviswanathan, Lee, Nissim, Raskhodnikova, and Smith; FOCS 2008] initiated such a discussion. They formalized the notion of private learning, as a combination of PAC learning and differential privacy, and investigated what concept classes can be learned privately. Somewhat surprisingly, they showed that, ignoring time complexity, every PAC learning task could be performed privately with polynomially many samples, and in many natural cases this could even be done in polynomial time.
While these results seem to equate non-private and private learning, there is still a significant gap: the sample complexity of (non-private) PAC learning is crisply characterized in terms of the VC-dimension of the concept class, whereas this relationship is lost in the constructions of private learners, which exhibit, generally, a higher sample complexity.
Looking into this gap, we examine several private learning tasks and give tight bounds on their sample complexity. In particular, we show strong separations between sample complexities of proper and improper private learners (such separation does not exist for non-private learners), and between sample complexities of efficient and inefficient proper private learners. Our results show that VC-dimension is not the right measure for characterizing the sample complexity of proper private learning.
We also examine the task of private data release (as initiated by [Blum, Ligett, and Roth; STOC 2008]), and give new lower bounds on the sample complexity. Our results show that the logarithmic dependence on size of the instance space is essential for private data release.

AB The emergence of a self-organized reversed-field pinch (RFP) helical regime, first shown by 3D MHD numerical simulations, has been highlighted in the RFX-mod experiment at high current operation (IP above 1 MA). In fact, a quasi-stationary helical configuration spontaneously appears, characterized by strong internal electron transport barriers. In such regime electron temperature and density become, to a very good approximation, functions of the helical flux coordinate related to the dominant helical magnetic component. In addition, this regime is diagnosed to be associated with the topological transition to a single-helical-axis (SHAx) state, achieved after the expulsion of the separatrix of the dominant mode's magnetic island. The SHAx state is theoretically predicted to be resilient to the magnetic chaos induced by secondary modes. In this paper, we present initial results of the volume-preserving field line tracing code nemato [Finn J M and Chacon L 2005 Phys. Plasmas 12 054503] applied to study the magnetic topology resulting from 3D MHD simulations of the RFP. First, a successful 2D verification test of the code is shown, then, initial application to a systematic study of chaos healing in the helical RFP is discussed. The separatrix disappearance is confirmed to play an essential role for chaos healing. The triggering effect of a reversed magnetic shear for the formation of ordered surfaces within magnetic chaos is also diagnosed.

AB Phase change materials (PCMs) are used in building envelopes in many forms. The PCMs may be encased in discrete pouches or containers, or they may be distributed within another medium, such as in a board or within a loose-fill insulation product. In addition, most PCM products are blends containing fire retardants and chemical stabilizers. A combined experimental-analytical protocol involving these complex systems has been developed to determine the actual amount of phase-change energy available to provide useful thermal storage since currently used small scale testing of individual materials is shown to be inadequate.
This paper presents this new methodology for performing dynamic heat flow analysis of complex PCM-enhanced building materials. The experimental analytical protocol uses a conventional heat-flow apparatus and three-dimensional (3-D), finite-difference modeling. Based upon results from this methodology, a simplified one-dimensional (1-D) model that can be easily used in whole-building simulations was developed. This paper describes this methodology as applied to an insulation assembly containing a complex array of PCM pouches.

AB Residential and commercial roofs and walls are currently designed and tested using steady-state criteria. The resulting R-values, based on the apparent thermal conductivity, are used by building standards as an important measure of energy performance. Building envelope components, however, are subject to dynamic environmental conditions. This mismatch between the steady-state principles used in design and code requirements and their dynamic operation results in relatively low thermal efficiencies. Although several research centers have developed experimental methods for transient analysis of building envelopes, there are no standardized testing procedures available for screening materials and systems for which performance depends on dynamic response. For example, a full-scale dynamic evaluation of phase change materials (PCMs) is needed to assess their energy saving benefits.
A nationally accepted small-scale (one to two foot size specimens) testing procedure is not available for the analysis of dynamic thermal characteristics of conventional thermal mass systems or PCM-enhanced materials. At the same time, data on these characteristics are necessary for whole-building simulations, energy analysis, and energy code work. The transient characteristics of PCM-enhanced products depend on the PCM content and quality. The only readily available method of thermal evaluation uses the differential scanning calorimeter. Unfortunately, this method requires small, relatively uniform test specimens. This requirement is unrealistic in the case of PCM-enhanced building envelope products such as PCM-cellulose, PCM-glass fiber, or PCM-gypsum blends. Small specimens are not representative of PCM-based blends, since these materials are not homogeneous.
A procedure for making dynamic heat-flow measurements using existing instrumentation has been developed to analyze the benefits of thermal storage. This small-scale testing method is useful for thermal analysis and as a potential quality control method for producers of PCM-enhanced building materials. The research may provide the basis for consensus standard development. This paper uses as an example a dynamic testing process for PCM-enhanced cellulose insulation.

ID CARBON-STEELS; MICROSTRUCTURE; IRON
AB The exceptional high hardness of lath martensite in quenched Fe-C steels is explained by the Engel-Brewer valence electron theory for crystal structures. The theory predicts the transformation sequence FCC-HCP-BCC with FCC iron as Fe-3v, HCP iron as Fe-2v, BCC iron as Fe-Iv and carbon as C-4v. Electronic compatibility requires transformation from FCC to HCP to form two separate components. Carbon-rich clusters of C-4v with 8 Fe-3v atoms are distributed uniformly in a carbon-free matrix of HCP Fe-2v atoms. The carbon-iron clusters are viewed as particle-like, calculated as 0.63 nm in size, and is responsible for the high strength of martensite. The carbon-free region experiences shear deformation during FCC to HCP transformation leading to work hardened fine grains Subsequent transformation to BCC iron maintains the same size carbon cluster with additional shearing deformation during HCP to BCC formation in the carbon-free region Tempering studies of quenched martensite are shown to support the carbon-iron cluster model.

DE two-scale; finite element; heterogeneous
AB In engineering applications, simulations involving heterogeneous materials where it is necessary to capture the local response coming from the heterogeneities is very difficult. The use of homogenization techniques can reduce the size of the problem but will miss the local effects. Homogenization can also be difficult if the constituents obey different constitutive laws. Additional complications arise if inelastic deformation occurs. In such cases a two-scale approach is preferred and this work addresses these issues in the context of a two-scale Finite Element Method (FEM). Examples of using two-scale FEM approaches are presented.

AB We explored the effect of K and K-Na substitution for Pb atoms in the lattice of PbTe, in an effort to test a hypothesis for the development of a resonant state that may enhance the thermoelectric power. At 300K the data can adequately be explained by a combination of a single and two-band model for the valence band of PbTe depending on hole density that varies in the range 1-15 x 10(19) cm(-3). A change in scattering mechanism was observed in the temperature dependence of the electrical conductivity, s, for samples concurrently doped with K and Na which results in significantly enhanced s at elevated temperatures and hence power factors. Thermal conductivity data provide evidence of a strong interaction between the light-and the heavy-hole valence bands at least up to 500K. Figure of merits as high as 1.3 at 700K were measured as a result of the enhanced power factors.

AB PbTe-based materials are promising for efficient heat energy to electricity conversion. We present studies of the thermoelectric properties of the PbTe-SrTe system. X-ray diffraction patterns reveal that all the samples crystallize in the rock salt structure without noticeable secondary phase. Na2Te doping of the PbTe-SrTe materials resulting in a positive sign Hall coefficient indicating p-type conduction. Lattice thermal conductivity is significantly decreased with the insertion of SrTe in PbTe lattice. The ZT similar to 1.3 of these materials is derived from their very low thermal conductivities and reasonably high power factor at 800 K.

AB We report on the thermoelectric properties of the filled skutterudite Ce0.9Fe3CoSb12 prepared via non-equilibrium synthesis method. Melt-spun ribbons were directly converting into single phase polycrystalline pellets under pressure. For comparison, pellets with the same composition were also prepared using the conventional solid-state reaction followed by long term annealing. It was found that the non-equilibrium synthesized samples have higher power factors and lower thermal conductivity, leading to substantially higher figure of merit.

AB The synthesis and properties characterization of several PbS1-xTex x =0-0.16 samples are presented. Notably it is shown how a local minimum occurs in the thermal diffusivity for the PbS1-x Te-x samples at x similar to 0.03. The thermoelectric properties of doped PbS1-x Te-x with x = 0.03 are reported and the properties are compared to the pure PbS and PbTe end members. The electronic contribution to the total thermal conductivity is analyzed for PbS1-x Te-x x = 0.03 and it is shown how the lattice thermal conductivity is significantly lowered compared to single crystalline PbS.

ID SYSTEM
AB A series of LaCo1-xRhxO3 (x=0-1) samples and La1-ySryCo1-xRhxO3 (y=0.05, 0.15 and x =0.1-0.3) samples were prepared to study the effect of Rh substituion for Co in the four component system and Sr substitution for La in the five component system on the crystal structure and thermoelectric performance of the LaCoO3. At Rh substitution for Co of x=0.2 greater, the crystal structure shifts from rhombohederal (LaCoO3) to orthorhombic (LaRhO3). Thermoelectric evaluation revealed that Rh doped samples (0.3 < x < 1) show large positive seebeck coefficients indicating a P-type conduction in the temperature range of the tests (273 to 775K). Rh substitution for Co decreases thermal conductivity, increases Seebeck coefficient and consequently increases the theroelectric figure of merit ZT. Sr substitution for La increases thermal and electrical conductivity and consquenently negligiblely decreases the seebeck coefficient. A thermoelectric figure-of-merit (ZT) around 0.075 has been achieved for LaCo0.5Rh0.5O3 at 775 K, and is expected to be above 0.1 at 1000 K. Sr substitution improved the TE properties throughout the lower temperature range with a ZT=0.045 observed for La0.95Sr0.05Co0.9Rh0.1O3 at 425 K and ZT =0.05 for La0.85Sr0.15Co0.5Rh0.5O3 at 775 K. These findings provide new insight into thermoelectric perovskite oxides containing rhodium and strontium.

AB We have prepared a variety of filled skutterudites through non-equilibrium synthesis by converting melt-spun ribbons into single phase polycrystalline bulk under pressure. In general, better thermoelectric properties are found in these samples. In this work, we performed microstructure characterization of non-equilibrium synthesized p-type filled skutterudite CeFe4Sb12 by X-ray diffraction, scanning electron microscopy and transmission electron microscopy in order to understand the structural origin of the improved thermoelectric properties. It is found that the non-equilibrium synthesized samples have smaller grain size and cleaner grain boundaries when compared to the samples prepared by the conventional solid-state reaction plus long term annealing. While smaller grain size can help reduce the lattice thermal conductivity, cleaner grain boundaries ensure higher carrier mobility and subsequently, higher electrical conductivity at the application temperatures.

AB The Rochester Institute of Technology (RIT) collected visible, SWIR, MWIR and LWIR imagery of the Midland (Michigan) Cogeneration Ventures Plant from aircraft during the winter of 2008 - 2009. RIT also made ground-based measurements of lake water and ice temperatures, ice thickness and atmospheric variables. The Savannah River National Laboratory (SRNL) used the data collected by RIT and a 3-D hydrodynamic code to simulate the Midland cooling lake. The hydrodynamic code was able to reproduce the time distribution of ice coverage on the lake during the entire winter. The simulations and data show that the amount of ice coverage is almost linearly proportional to the rate at which heat is injected into the lake (Q). Very rapid melting of ice occurs when strong winds accelerate the movement of warm water underneath the ice. A snow layer on top of the ice acts as an insulator and decreases the rate of heat loss from the water below the ice to the atmosphere above. The simulated ice cover on the lake was not highly sensitive to the thickness of the snow layer. The simplicity of the relationship between ice cover and Q and the weak responses of ice cover to snow depth over the ice are probably attributable to the negative feedback loop that exists between ice cover and heat loss to the atmosphere.

The reduction potential from the cyclic voltammogram studies indicates that the first deposited layer is Cu from the Cu-In-Se and Cu-In-Ga-Se solution mixture. The subsequent deposition of the In and Ga layer is more favorable on the first-deposited Cu layer.

AB Several wet-processing steps are used in fabricating high-efficiency CdTe/CdS solar cells. These steps can hinder in-line processing; thus, developing an all-dry processing option is attractive for a manufacturing-friendly process. In this study, we systematically modified the baseline process used in our laboratory to replace CdS deposited by chemical-bath deposition (CBD) with sputter-deposited CdS and Cu-doped graphite paste back-contact with Cu-doped ZnTe deposited by radio-frequency sputtering. In addition to CdTe deposited by close-spaced sublimation, we also used conventionally evaporated CdTe. The results show that replacing only CBD CdS with oxygenated CdS deposited by sputtering produces devices with performance comparable to baseline devices if the front bilayer SnO2 is replaced by a Cd2SnO4/ZnSnO alloy. Replacing the graphite paste back-contact with sputter-deposited Cu-doped ZnTe resulted in device performance comparable to baseline devices. Incorporating both dry processing steps gave performance comparable to the devices with sputtered CdS with a SnO2 front contact. We used capacitance-voltage and minority-carrier lifetime measurements to analyze the factors affecting device performance and we present the results here.

AB Chemical bath deposition (CBD) is a commonly used method of depositing cadmium sulfide (CdS) films for photovoltaic application. The method is based on decomposition of a sulfur source in an alkaline solution of a cadmium source on the surface of the Cu(In,Ga)Se-2 (CIGS) substrate. On the lab scale the CdS film is deposited by submerging a 1 '' square CIGS substrate in a heated beaker containing the chemical bath. This batch processing method is the one used for record-performing devices. There is an ongoing effort at the National Renewable Energy Laboratory to scale-up the CBD process to deposit CdS films on 6 '' square substrate. Efforts are focused at designing both batch and flow reactors for depositing uniform, device quality CdS films on larger substrates. Batch reactor designs involve reproducing the deposition process in the beaker on a bigger scale with minimal chemical waste, while flow reactors are designed for continuous processing, such as encountered in roll-to-roll manufacturing lines.

AB Tin oxide (SnO(2)) is a durable, inexpensive transparent conducting oxide (TCO) material used for thin-film photovoltaic devices. However, the optical properties of conducting SnO(2):F are generally not as good as in other conducting TCO materials such as ITO and ZnO:Al. Our previous analyses indicate that for thin-film solar cells, improving the optical properties of SnO(2)-coated glass could enhance photon collection and gain up to 10% additional photocurrent. Previously, we showed that some commercial SnO(2) samples could have much higher optical absorption than others [2]. In this work, we continue our study on causes that could contribute to the high optical absorption of SnO(2) films. The SnO(2):F samples are fabricated by low-pressure metal-organic chemical vapor deposition or atmospheric-pressure chemical vapor deposition with tin precursors that includes different amounts of chlorine. Optical, electrical, and compositional analyses were performed. In addition to the free-carrier-introduced optical absorption, the non-active dopant also impacts the optical absorption. Among the SnO2 films fabricated with different precursors, the optical properties show a relationship based on the level of chlorine in the precursors and films. With a low-optical-absorption SnO(2) layer, the solar cell could have better photon collection and a higher short-circuit current density.

AB We have shown that variation in the real part of the dielectric permittivity of typical transparent conducting oxide (TCO) films can have a profound effect on the optical properties of the material. This has been demonstrated by adding small amounts of Zr to an ITO ceramic sputtering target and analyzing the resulting ITO and ITO:Zr (ITZO) films. Comparative electrical and optical analyses of the films show that, although the carrier concentration and mobility do not change appreciably by adding 1 wt.% ZrO(2) to the ITO sputtering target, the plasma wavelength increases significantly for the ITZO film. We believe that the underlying physics of these results can be exploited in designing future TCO films for photovoltaic (PV) applications especially those that embody industrial advantages but remain limited by low mobility.

The latter method proved to be the most reliable, with a success rate of over 90%.
We investigated cross sections of CdTe/CdS samples with scanning Kelvin probe microscopy (SKPM) using two different methods: applying the alternate bias with a frequency equal to 18.5 kHz, or equal to the frequency of the second cantilever resonance peak. The results showed that using the second resonance frequency produced a smoother signal, allowing the calculation of the electric field inside the device using just the raw SKPM data.
We were able to measure the distribution of the electrical potential inside working devices. Then, by taking the first derivative of the potential, we calculated the electric field and determined the location of the p-n junction.

AB Two types of commercial electrically conductive adhesive (CA) tapes, one isotropic and the other anisotropic, were investigated for their potential application as interleafing connects for flexible thin-film photovoltaic modules. The performance stability of their vacuum-laminated sample constructs between two 50-mu m stainless steel (SS) foils and between the SS foil and bilayer ZnO/Mo-coated SS foil was evaluated upon damp-heat and dry-heat exposure. Preliminary results indicated that the isotropic CA tape was more stable than the anisotropic tape.

AB Polycrystalline Cd(1-x)Mg(x)Te (CMT) thin films are a potential absorber material for two-junction thin-film tandem solar cell applications because the desired top cell bandgap range of 1.6 to 1.8 eV is readily obtained using CMT with only small resultant changes in the lattice constant from that of CdTe. Tandem devices require the top cell to have a transparent back contact to transmit the sub-bandgap spectrum to the bottom cell. Sputtered Cu-doped ZnTe (ZnTe:Cu) thin films, which offer potential as a transparent back contact interface layer, have been used successfully in CdTe devices. We apply ZnTe:Cu back contacts to CMT devices to continue development toward a transparent top cell. We describe the effects of depositing ZnTe:Cu at different temperatures and with different Cu contents on the net acceptor concentration, minority carrier lifetime, and device performance. We present here the highest reported CMT device efficiency of 9.6% at a bandgap of 1.57 eV.

AB We report on recent advances in the development of a luminescence spectroscopy based on scanning tunneling microscopy (STM) and its application to fundamental aspects of Cu(In,Ga)Se(2) (CIGS) thin films. Relevant to our discussion is the specifics of the surface electronics. The CIGS shows pronounced stoichiometric deviations at the surface and, consequently, distinct surface electronics that has been shown to be critical in achieving high efficiency. Cathodoluminescence (CL), a luminescence spectrum imaging mode in scanning electron microscopy (SEM), provides a direct correlation between the Microstructure of the CIGS and its electronic properties. As such, cathodoluminescence can resolve the emission spectrum between grain boundaries and grain interiors or be used to investigate the influence of local orientation and stoichiometry on the electronic properties of the CIGS at the microscale. Cathodoluminescence is not a surface microscopy, however, and resolving the electronic structure of the CIGS surface remains elusive to all luminescence microscopies. With this motivation, we have developed a luminescence microscopy based on STM, in which tunneling electrons are responsible for the excitation of luminescence (scanning tunneling luminescence or STL). The hot-tunneling-electron excitation is confined to the surface and, consequently, the tunneling luminescence spectrum reveals the electronic states near the surface. The STM is integrated inside the SEM and, therefore, both CL and STL can be measured over the same location and compared. Using this setup, the transition from the grain interior to the surface can be investigated. We have improved the collection of our optics to a level in which tunneling luminescence spectrum imaging can be performed. Here we present a detailed account on our investigation of the surface electronics in CIGS deposited in the regime of selenium deficiency as defined by < Se >/(< Cu >> + < In > + < Ga >) = 1.

AB Although the first epitaxial films of YBCO with high T-c were grown nearly 20 years ago, the understanding and control of the nanostructures responsible for the dissipation-free electrical current transport in high temperature superconductors (HTS) is quite recent. In the last 6-7 years, major advances have occurred in the fundamental investigation of low angle grain boundaries, flux-pinning phenomena, growth mode, and atomic-level defect structures of FITS epitaxial films. As a consequence, it has been possible to map and even engineer to some extent the performance of HTS coatings in large regions of the operating H, T J phase space. With such progress, the future of high temperature superconducting wires looks increasingly promising despite the tremendous challenges offered by these brittle and anisotropic materials. Nevertheless, further performance improvements are necessary for the superconducting technology to become cost-competitive against copper wires and ultimately succeed in revolutionizing the transmission of electricity. This can be achieved by further diminishing the gap between theoretical and experimental values of the critical current density J(c), and/or increasing the thickness of the superconductive layer as much as possible without degrading performance. In addition, further progress in controlling extrinsic and/or intrinsic nano-sized defects within the films is necessary to significantly reduce the anisotropic response of HTS and obtain a nearly constant dependence of the critical current on the magnetic field orientation, which is considered important for power applications. This chapter is a review of the challenges still present in the area of superconducting film processing for HTS wires and the approaches currently employed to address them.

AB Metal oxides are fundamentally important as heterogeneous catalysts either as stand-alone catalysts or in combination with other oxides and/or metals. In this chapter, we focus on how the use of thin film metal oxides, in lieu of bulk oxides, can potentially enhance catalytic activity. We illustrate this concept with two examples. In the first example, we discuss a molybdenum trioxide monolayered structure that can be grown on the gold (111) surface. In contrast to the bulk molybdenum trioxide that is composed of bilayers, this oxide monolayer is semimetallic and has distinct chemical properties. In the second example, we propose that ultrathin oxide layers can enable the coupling of structural distortions and charge transfer beyond that allowed in the bulk, and that ultrathin oxide supports can play a dynamic, active, role in promoting catalysis in supported metal catalysts.

AB NREL CIGS devices with up to 20% efficiency are prepared using a three-stage process for the CIGS layer with the last step of an intrinsic ZnO and conductive ZnO:Al bilayer. This work outlines the efficiency and performance parameters for these CIGs devices when this bilayer is replaced with indium zinc oxide (a-InZnO), an amorphous metal oxide. It is well known that metal oxides can serve a variety of important functions in thin film photovoltaics such as transparent electrical contacts (TCO's), antireflection coatings and chemical barriers. In the case of a-InZnO, we have reported on the determination of the relative roles of metals and oxygen stoichiometries on the opto-electronic properties of a-InZnO thin films as well as the stability of those films in damp heat. Since InZO has a tunable conductivity based on the amount of oxygen introduced during deposition, it can be used as both the intrinsic and TCO layers. We were able to establish preliminary metrics for an all InZnO bilayer whose performance was comparable to a common CIGs device.

AB We study the electromagnetic (EM) response of anisotropic eutectic metamaterials, consisting in cylindrical polaritonic LiF rods embedded in a KCl host. The specular reflectance of the samples was measured at far infrared (3-12 THz). The sample reflection was simulated by modeling the eutectic structure and solving numerically Maxwell equations for the EM fields. The reflectance was also calculated from simple effective response functions models. A good agreement was obtained between experimental and calculated spectra. From the effective response functions calculations, we obtained a range of frequencies in which the system behaves as a homogeneous effective anisotropic media, with a hyperbolic dispersion relation, opening possibilities for negative refraction and focusing applications.

AB Fluorescence fluctuation analysis of dilute biomolecules can provide a powerful method for fast and accurate determination of diffusion dynamics, local concentrations, and aggregation states in complex environments. However, spectral overlap among multiple exogenous and endogenous fluorescent species, photobleaching, and background inhomogeneities can compromise quantitative accuracy and constrain useful biological implementation of this analytical strategy in real systems. In order to better understand these limitations and expand the utility of fluctuation correlation methods, spatiotemporal fluorescence correlation analysis was performed on spectrally resolved line scanned images of modeled and real data from mixed fluorescent nanospheres in a synthetic gel matrix. It was found that collecting images at a pixel sampling regime optimal for spectral imaging provides a method for calibration and subsequent temporal correlation analysis which is insensitive to spectral mixing, spatial inhomogeneity, and photobleaching. In these analyses, preprocessing with multivariate curve resolution (MCR) provided the local concentrations of each spectral component in the images, thus facilitating correlation analysis of each component individually. This approach allowed quantitative removal of background signals and showed dramatically improved quantitative results compared to a hypothetical system employing idealized filters and multi-parameter fitting routines.

AB The Laser Inertial Fusion-based (LIFE) engine is an advanced energy concept under development at Lawrence Livermore National Laboratory (LLNL). LIFE engine could be used to drive a subcritical fission blanket with fertile or fissile fuel. Current LIFE engine designs envisages fuel in pebble bed form with TRISO (tristructural isotropic) particles embedded in a graphite matrix, and pebbles flowing in molten salt Flibe (2LiF+BeF(2)) coolant at T-700C. Weapons-grade plutonium (WGPu) fuel is an attractive option for LIFE engine involving the achievement of high fractional burnups in a short lifetime frame. However, WGPu LIFE engine operating conditions of high neutron fast fluence, high radiation damage, and high Helium and Hydrogen production pose severe challenges for typical TRISO particles. The thermo-mechanical fuel performance code HUPPCO (High burn-Up fuel Pebble Performance COde) currently under development accounts for spatial and time dependence of the material elastic properties, temperature, and irradiation swelling and creep mechanisms. In this work, some aspects of the thermo-mechanical response of TRISO particles used for incineration of weapons grade fuel in LIFE engine are analyzed. Preliminary results show the importance of developing reliable high-fidelity models of the performance of these new fuel designs and the need of new experimental data relevant to WGPu LIFE conditions.

AB IPM is a profiling and workload characterization tool for MPI applications. IPM achieves its goal of minimizing the monitoring overhead by recording performance data in a fixed-size hashtable resident in memory and by carefully optimizing time-critical operations. At the same time, IPM offers very detailed and user centric perfoituance metrics. IPM's performance data is delivered as an XML file that can subsequently be used to generate a detailed profiling report in HTML format, avoiding the need for custom GUI applications. Pairwise communication volume and communication topology between processes, communication time breakdown across ranks, MPI operation timings, and MPI message sizes (buffer lengths) are some of IPM's most widely used metrics. IPM is free and distributed under the LGPL license.

AB The Message-Passing Interface (MPI) is large and complex. Therefore, programming MPI is error prone. Several MPI runtime correctness tools address classes of usage errors, such as deadlocks or non-portable constructs. To our knowledge none of these tools scales to more than about 100 processes. However, some of the current HPC systems use more than 100,000 cores and future systems are expected to use far more. Since errors often depend on the task count used, we need correctness tools that scale to the full system size. We present a novel framework for scalable MPI correctness tools to address this need. Our fine-grained, module-based approach supports rapid prototyping and allows correctness tools built upon it to adapt to different architectures and use cases. The design uses (PMPI)-M-n to instantiate a tool from a set of individual modules. We present an overview of our design, along with first performance results for a proof of concept implementation.

AB Modern high performance computer systems continue to increase in size and complexity. Tools to measure application performance in these increasingly complex environments must also increase the richness of their measurements to provide insights into the increasingly intricate ways in which software and hardware interact. PAPI (the Performance API) has provided consistent platform and operating system independent access to CPU hardware performance counters for nearly a decade. Recent trends toward massively parallel multi-core systems with often heterogeneous architectures present new challenges for the measurement of hardware performance information, which is now available not only on the CPU core itself, but scattered across the chip and system. We discuss the evolution of PAPI into Component PAPI, or PAPI-C, in which multiple sources of performance data can be measured simultaneously via a common software interface. Several examples of components and component data measurements are discussed. We explore the challenges to hardware performance measurement in existing multi -core architectures. We conclude with an exploration of future directions for the PAPI interface.

AB We have calculated r-process nucleosynthesis based on acoustic wave driven supernova simulation. The environment includes extremely high entropy cases which has not been studied in previous studies. Plenty of actinide and third peak elements are formed in an averaged abundance, while elements around the first and second peaks are overproduced. We also studied the effect of direct capture in r-process. The direct capture furthers r-process and make freeze out earlier. It will change the final abundance drastically. We recalculated r-process nucleosynthesis of the simulation considering the direct capture reaction. While we could not see a significant difference in averaged abundances, significant differences appeared in several individual yields.

AB S-3 (Super Separator Spectrometer) is a device designed for experiments with the very high intensity stable beams of LINAG, the superconducting linear accelerator of GANIL, which will be built in the framework of SPIRAL2. These beams, which will provide ions with A/Q = 3 in SPIRAL2 phase one, can reach intensities up to 1mA for light ions, A<50. These unprecedented intensities open new opportunities in several physics domains, e.g. super-heavy and very-heavy nuclei, spectroscopy at and beyond the drip line, isomers and ground state properties, multi-nucleon transfer and deep-inelastic reactions. An international collaboration has been formed to propose physics experiments and develop technical solutions for this new instrument.

AB LHCf measures the energy and transverse momentum of neutral particles produced in the forward region of the LHC interaction point. In high energy cosmic ray measurements, the results strongly depend on the hadron interaction model which is used in the air shower simulation. LHCf will take data at root s= 0.9, 2.4, 7, 10 and 14 TeV collisions at LHC and provide crucial calibration points for the hadron interaction models.

AB The incipient lethal temperature (ILT) and critical thermal maximum (CTM) methods are used to set temperature limits for fish. However, the standard application of these methods does not always match the temperature regimes that fish experience in the wild. We used alternative methods to determine the thermal tolerance thresholds of juvenile fall-run Chinook salmon Oncorhynchus tshawytscha exposed to the temperature regimes that are common in the entrapment pools that form along the shoreline of the Snake River when flows are altered to meet electric power demand. A modified CTM test with a steady temperature rise (1.5 degrees C/h) showed that one-half the fish died when temperatures reached 27.4-27.9 degrees C and that survival at 25 degrees C was highly variable; the average time to the first death was 9.1 h, varying from 1.7 to 22.5 h. Over 30 d, 99.8% of the fish in the constant temperature regimes (14-22 degrees C) survived. In the fluctuating temperature regimes (which varied from 10-14 degrees C to 22-27.5 degrees C), overall survival was 97.3%; however, only 83.0% and 88.9% survived in the groups that reached daily maximums of 27 degrees C and 27.5 degrees C, respectively. Growth over 30 d in the constant thermal regimes was nearly twice as high as that in the fluctuating regimes, even when daily average temperatures were similar. The maximum growth was 1.9%/d in terms of fork length [FL] and 11.2%/d in terms of weight (WT) at a constant 20 degrees C. The lowest growth occurred in the two groups exposed to daily temperatures of 27 degrees C or more, namely, 0.7-0.8% (FL) and 2.7-3.4% (WT). The results of this study suggest that thermal tolerance tests that expose juvenile fall Chinook salmon to thermal regimes that match the field conditions in entrapment pools along the shoreline of the Snake River provide higher temperature criteria than the standard ILT and CTM methods.

TI EFFECT OF ENDOSPERM HARDNESS ON AN ETHANOL PROCESS USING A GRANULAR

AB Granular starch hydrolyzing enzymes (GSHE) can hydrolyze starch at low temperature (32 degrees C). The dry grind process using GSHE (GSH process) has fewer unit operations and no changes in process conditions (pH 4.0 and 32 degrees C) compared to the conventional process because it dispenses with the cooking and liquefaction step. In this study, the effects of endosperm hardness, protease, urea, and GSHE levels on GSH process were evaluated. Ground corn, soft endosperm, and hard endosperm were processed using two GSHE levels (0.1 and 0.4 mL per 100 g ground material) and four treatments of protease and urea addition. Soft and hard endosperm materials were obtained by grinding and sifting flaking grits from a dry milling pilot plant; classifications were confirmed using scanning electron microscopy. During 72 h of simultaneous granular starch hydrolysis and fermentation (GSHF), ethanol and glucose profiles were determined using HPLC. Soft endosperm resulted in higher final ethanol concentrations compared to ground corn or hard endosperm. Addition of urea increased final ethanol concentrations for soft and hard endosperm. Protease addition increased ethanol concentrations and fermentation rates for soft endosperm, hard endosperm, and ground corn. The effect of protease addition on ethanol concentrations and fermentation rates was most predominant for soft endosperm, less for hard endosperm, and least for ground corn. Samples (soft endosperm, hard endosperm, or corn) with protease resulted in higher (1.0% to 10.5% v/v) ethanol concentration compared to samples with urea. The GSH process with protease requires little or no urea addition. For fermentation of soft endosperm, GSHE dose can be reduced. Due to nutrients (lipids, minerals, and soluble proteins) present in corn that enhance yeast growth, ground corn fermented faster at the beginning than hard and soft endosperm.

ID EQUATIONS
AB We extend moment analysis, a technique developed for investigating the accuracy of discrete-ordinates spatial discretization schemes, to time-dependent radiation transport and apply it to several angular approximation methods. Specifically, we examine the diffusion approximation, the P(1/3) approximation, and three time-dependent generalizations of the simplified P(N) approximation: the SP(2), SP(3), and SSP(3) approximations. We show that all of the these methods preserve the correct flux-weighted average of x but not the correct flux-weighted average of (x - x(a))(2), where x is the spatial variable and x(a) is an arbitrary point. We also demonstrate that, for general cross sections and large elapsed time, the error in the flux-weighted average of (x - x(a))(2) is smallest in magnitude for the SP(2) and SP(3) approximations. In addition, we present a simple improvement to the SP(2) approximation that allows this method to produce the correct flux-weighted average of (x - x(a))(2). We present numerical results that test this analysis. From these results, we find that the angular approximation methods with the most accurate solutions also have the most accurate values for the flux-weighted average of (x - x(a))(2). In particular, the SP(2) and SP(3) approximations are two of the most accurate methods at large elapsed times, while the improved SP(2) approximation is one of the most accurate methods at all times. We also observe, however, that an accurate value for the flux-weighted average of (x - x(a))(2) is not always accompanied by an accurate solution. Consequently, we conclude that an accurate flux-weighted average of (x - x(a))(2) is a necessary rather than sufficient condition for an overall accurate angular approximation method.

TI Effect of Wide-Based Single Tires on Fuel Efficiency of Class 8
Combination Trucks
SO TRANSPORTATION RESEARCH RECORD
LA English
DT Article
AB In 2007 and 2008, the Oak Ridge National Laboratory, in collaboration with several industry partners, collected real-world performance and situational data for long-haul operations of Class 8 trucks from a fleet engaged in normal freight operations. Such data and information are useful to support Class 8 modeling of combination truck performance and technology evaluation efforts for energy efficiency and to provide a means of accounting for real-world driving performance within combination truck research and analyses. Some general statistics, including distribution of idling times during long-haul trucking operations, are presented. However, the main focus is on the analysis of some of the extensive real-world information collected in this project, specifically on the assessment of the effect that different types of tires [i.e., dual tires versus new generation wide-based single tires (NGWBSTs)] have on the fuel efficiency of Class 8 trucks. The tire effect is also evaluated as a function of the vehicle load level. In all cases analyzed, the statistical tests strongly suggest that fuel efficiencies achieved when all NGWBSTs or combinations of duals and NGWBSTs are used are higher than in the case of a truck equipped with all dual tires. The results show that the fuel efficiency improvement increases as the number of NGWBSTs on the truck increases, with observed improvements of around 6% when either the tractor or the trailer was equipped with NGWBSTs and more than 9% when both were mounted with these types of tires.

AB Calcium silicate hydrate (C-S-H) is the main hydration product of portland cement. Studying the structural and chemical decomposition of C-S-H after carbonation is critical for determining the durability and serviceability of concrete. Recent studies showed that the mechanical properties are likely to be enhanced when mineral admixtures and polymers are introduced. So far, no molecular-level studies have been conducted on carbonated C-S-H material to clarify these effects. In this research, scanning transmission X-ray microscopy (STXM) is used to study C-S-H modified with two organic polymers (hexadecyltrimethylammonium and polyethylene glycol 200) and exposed to different reaction times with CO(2). STXM uses light in the soft X-ray region where a number of atomic resonances are present. By tuning the X-ray energies to a certain absorption edge, elemental and chemical identification was performed. The energy of the X-rays was tuned to the C K-edge, Ca L(2,3)-edge, and Si K-edge. Detailed images were also recorded with a lateral resolution of 30 nm. Structural, elemental, and chemical heterogeneities were spatially identified. Significant differences were found in carbon spectra in the atmospheric and 48-h continuous CO(2)-carbonated C-S-H samples, suggesting that carbon-containing precipitates formed within a C-S-H matrix differ depending on the extent of carbonation. Si K-edge spectra suggest increased polymerization of silicates depending on the duration of CO(2) exposure. This study found that the degree of silicate polymerization and the coordination environment for carbon-containing mineral phases vary with the CO(2) exposure level.

AB The impact of an intermodal facility on location and transportation decisions for biofuel production plants is analyzed. Location decisions affect the management of the inbound and outbound logistics of a plant. This supply chain design and management problem is modeled as a mixed integer program. Input data for this model are location of intermodal facilities and available transportation modes, cost and cargo capacity for each transportation mode, geographical distribution of biomass feedstock and production yields, and biomass processing and inventory costs. Outputs from this model are the number, location, and capacity of biofuel production plants. For each plant, the transportation mode used, timing of shipments, shipment size, inventory size, and production schedule that minimize the delivery cost of biofuel are determined. The model proposed in this research can be used as a decision-making tool for investors in the biofuels industry since it estimates the real cost of the business. The state of Mississippi is considered as the testing grounds for the model.

AB Self-assembled GaN and InN nanowires (NWs) were synthesized by radio frequency Plasma-Assisted Molecular Beam Epitaxy (PAMBE) without external catalyst. NWs of micrometers length and diameter in the range of 20-200 nm are fabricated using this method under N-rich conditions. Driving mechanisms of the NW nucleation and the growth are discussed. The NWs have been investigated using scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), atomic force microscopy (AFM), and photoluminescence (PL). Electric and photoelectric measurements on single wire devices have been performed as well. We establish that the dark, Ultraviolet (UV) photo-current and band-edge absorption tails in GaN NWs are strongly dependent on wire diameter. A model of surface Fermi level pinning and Franz-Keldysh effect in carrier depletion region at wire surface were used to explain the observed behaviors. InN NWs show infrared (IR) photoluminescence strongly dependent on the growth parameters. High electron concentration of 10(18) - 10(19) cm(-3) was evaluated from line shape analysis of PL spectra. The Fermi level pinning at the surface corresponds to a surface accumulation layer. To modify the surface of InN NWs, core-shell InN/GaN NWs were grown. In this paper we focus on the influence of surface effects on the growth and properties of GaN and InN nanowires.

AB Current forest Free Air CO2 Enrichment (FACE) experiments are reaching completion. Therefore, it is time to define the scientific goals and priorities of future experimental facilities. In this opinion article, we discuss the following three overarching issues (i) What are the most urgent scientific questions and how can they be addressed? (ii) What forest ecosystems should be investigated? (iii) Which other climate change factors should be coupled with elevated CO2 concentrations in future experiments to better predict the effects of climate change? Plantations and natural forests can have conflicting purposes for high productivity and environmental protection. However, in both cases the assessment of carbon balance and how this will be affected by elevated CO2 concentrations and the interacting climate change factors is the most pressing priority for future experiments.

DE Rolling contact fatigue; Silicon nitride; Surface strength
AB Silicon nitride (Si(3)N(4)) has been used in various rolling contact applications in turbomachinery. automotive and power industry. It is favoured to replace conventional steel due to its low density, low friction, corrosion resistance and good performance under extreme condition. However, a major limitation of its wider application is its high material and machining cost, especially the cost associated with the finishing process. In the present study, a low cost sintered and reaction bonded silicon nitride (SRBSN) is used to study the surface machining effects on its rolling contact performance. Attempt has been made to link the surface strengths of Si(3)N(4) derived from half-rod and C-sphere flexure strength specimens to the rolling contact lifetimes of Si(3)N(4) rod and ball specimens. The rolling contact fatigue tests are carried out on ball-on-rod and modified four ball machines. Three types of surfaces with coarse, fine and conventional finishing conditions are examined. Flexure strength tests on half-rod and C-sphere show an increasing surface strength from specimens with coarse, fine to conventionally machined conditions. During rolling contact fatigue test of as-machined specimens, there are no failures observed on both ball-on-rod and four ball tests after 100 million stress cycles. However, there is a trend of decreasing wear volumes measured on the contact path of rods and balls with coarse, fine and conventional conditions. In four ball test, spall failures are observed on pre-crack specimens. There is a trend of increasing rolling contact fatigue lifetime from pre-cracked specimens with coarse, fine to conventional machining conditions. (c) 2009 Elsevier Ltd. All rights reserved.

AB The states of Rondonia and Mato Grosso in Brazil together make up the world's largest agricultural frontier. Between 2001 and 2004, deforestation, to provide land for highly mechanized agriculture in this area, reached unprecedented rates. The environmental consequences of this include increased greenhouse gas (GHG) emissions from above and below ground sources. In this area where agriculture is a relatively new activity, land use and management practices change rapidly as farmers react to market pressures but also use trial and error to increase productivity/reduce losses. Farmers routinely make use of the latest technologies making agricultural expansion very different from historical examples. The fact that systems are in a state of flux has implications for sustainability and the ability of scientists to produce local and national GHG inventories and project future GHG emissions and carbon stock changes. Such projections are necessary to assess the full environmental impacts of such large scale native vegetation loss and to inform policy makers accordingly.
A pilot study of farmer interviews around the town of Sinop, Mato Grosso, found that land management methods have varied over time, with a recent trend emerging to move from monoculture systems to integrated crop/livestock systems. The interviews also revealed that management practices employed by the small (<500 ha) farms differed markedly from those employed by medium (>500 ha) and large (>10,000 ha) farms. Wider studies carried out in the neighbouring state of Rondonia have shown soil C stocks and GHG emissions to be highly dependent on agricultural management. We discuss the implications of rapidly changing management practices in the agricultural frontier region of Mato Grosso and Rondonia on past regional estimates of C stocks and GHG fluxes and future projections. The future outlook is discussed in the context of possibility of REDD being included in a successor to the Kyoto Protocol.

ID MAGNETOHYDRODYNAMIC TURBULENCE; FLUCTUATIONS; VELOCITY
AB A theory of incompressible MHD turbulence with nonvanishing cross-helicity is derived based on two new observations from the Wind spacecraft. The first is the observation that the normalized cross-helicity sigma(c), is approximately scale-invariant throughout the inertial range. The second is the observation that the probabilities p and q for velocity and magnetic field fluctuations to be positively or negatively aligned are also approximately scale-invariant. The theory extends the theory of Boldyrev (2006) to turbulence with nonvanishing cross-helicity assuming that the cascades of the two Elsasser energies are both in a state of critical balance.

AB Wavelet analysis is a tool that can simultaneously analyze spacecraft data in both time and frequency. This enables the magnetic energy spectrum (trace spectrum) to be measured for different angles between the local mean magnetic field B(0) and the direction of the mean flow within a single data set. Examples obtained around solar minimum using Ulysses data at high latitudes and Stereo data for high-speed streams in the ecliptic plane show that the spectral exponent in the inertial range varies nearly monotonically from approximately 1.6 when B(0) is perpendicular to the flow to 2.0 when B(0) is parallel to the flow, roughly consistent with anisotropic theories of incompressible MHD turbulence. This and other new information about the 3D wavector spectrum of solar wind fluctuations in the inertial range and the dissipation range are briefly discussed.

AB Observed properties of the strahl using high resolution 3D electron velocity distribution data obtained from the Cluster/PEACE experiment are used to investigate its linear stability. An automated method to isolate the strata is used to allow its moments to be computed independent of the solar wind core+halo. Results show that the strahl can have a high temperature anisotropy (T-perpendicular to/T-parallel to greater than or similar to 2). This anisotropy is shown to be an important free energy source for the excitation of high frequency whistler waves. The analysis suggests that the resultant whistler waves are strong enough to regulate the electron velocity distributions in the solar wind through pitch-angle scattering.

DE Heliospheric Current Sheet; Solar wind/magnetosphere interactions
ID WIND; MAGNETOPAUSE; SURFACE; SHAPE
AB The heliospheric current sheet (HCS) is a permanent solar wind feature, with well predicted Earth passages, but it can be structured and its main orientation can be highly distorted. We report new observations from 2 spacecraft in the solar wind (supported by observations from 3 spacecraft in the nightside magnetosheath), showing an evolution across the Sun-Earth line of large field reversals adjacent to the HCS. Contrary to a previously reported multi-spacecraft event, this case shows that the field inversion structure cannot be assumed to be well preserved and close to planar on the scale of the magnetospheric cross-section. However, both cases indicate the presence of field reversals in an away sector that is connected to the southern solar magnetic hemisphere but lies unexpectedly above a toward sector. Following the interpretation of the reversals as transient outflowing loops, associated initial flow deviations can be envisaged to account for the HCS deformations.

AB Suprathermal electron heat flux dropouts (HFD) serve as a sensitive test of the magnetic topology of the inner heliosphere. Since the heat flux electron strahl always flows away from the Sun, a heat flux dropout should indicate either that the magnetic field line is completely disconnected from the Sun or that the heat flux strahl is scattered into other pitch angles. We present observations of two suprathermal electron heat flux dropout events observed by the Advanced Composition Explorer (ACE) spacecraft which occur simultaneously with impulsive energetic ion events. Since suprathermal electrons encompass the same velocity range as ions with energies of a few MeV/nucleon, the similarities and differences between them as observed at 1 AU probes the sources and transport of these two species. We compare the two events to show the difference between the signatures of a simple disconnection and a more complicated reconnection scenario. Comparing suprathermal electron modulations with energetic ion modulations is a powerful technique for determining the magnetic topology between particle injection at the Sun and observation at 1 AU.

AB Spectrum imaging (SI) methods are displacing traditional spot analyses as the predominant paradigm for spectroscopic analysis with electron beam instrumentation. The multivariate nature of SI provides clear advantages for qualitative analysis of multiphase specimens relative to traditional gray-scale images acquired with non-spectroscopic signals, where different phases with similar average atomic number may exhibit the same intensity. However, with the improvement in qualitative analysis with the SI paradigm has come a decline in the quantitative analysis of the phases thus identified, since the spectra from individual pixels typically have insufficient counting statistics for proper quantification. The present paper outlines a methodology for quantitative analysis within the spectral imaging paradigm, which is illustrated through X-ray energy-dispersive spectroscopy (EDS) of a multiphase (Pb,La)(Zr,Ti)O(3) ceramic in scanning transmission electron microscopy (STEM). Statistical analysis of STEM-EDS Sl is shown to identify the number of distinct phases in the analyzed specimen and to provide better segmentation than the STEM high-angle annular dark-field (HAADF) signal. Representative spectra for the identified phases are extracted from the segmented images with and without exclusion of pixels that exhibit spectral contributions from multiple phases, and subsequently quantified using Cliff-Lorimer sensitivity factors. The phase compositions extracted with the method while excluding pixels from multiple phases are found to be in good agreement with those extracted from user-selected regions of interest, while providing improved confidence intervals. Without exclusion of multiphase pixels, the extracted composition is found to be in poor statistical agreement with the other results because of systematic errors arising from the cross-phase spectral contamination. The proposed method allows quantification to be performed in the presence of discontinuous phase distributions and overlapping phases, challenges that are typical of many nanoscale analyses performed by STEM-EDS.

AB Atomic-resolution transmission electron microscopy has largely benefited from the implementation of aberration correctors in the imaging part of the microscope. Though the dominant geometrical axial aberrations can in principle be corrected or suitably adjusted, the impact of higher-order aberrations, which are mainly due to the implementation of non-round electron optical elements, on the imaging process remains unclear. Based on a semi-empirical criterion, we analyze the impact of residual aperture aberrations on the quality of exit-plane waves that are retrieved from through-focal series recorded using an aberration-corrected and monochromated instrument which was operated at 300 kV and enabled for an information transfer of similar to 0.05 nm. We show that the impact of some of the higher-order aberrations in retrieved exit-plane waves can be balanced by a suitable adjustment of symmetry equivalent lower-order aberrations. We find that proper compensation and correction of 1st and 2nd order aberrations is critical, and that the required accuracy is difficult to achieve. This results in an apparent insensitivity towards residual higher-order aberrations. We also investigate the influence of the detector characteristics on the image contrast. We find that correction for the modulation transfer function results in a contrast gain of up to 40%. (C) 2009 Elsevier B.V. All rights reserved.

AB We introduce a model of cavitation based on the multiphase Lattice Boltzmann method (LBM) that allows for coupling between the hydrodynamics of a collapsing cavity and supported solute chemical species. We demonstrate that this model can also be coupled to deterministic or stochastic chemical reactions. In a two-species model of chemical reactions (with a major and a minor species). the major difference observed between the deterministic and stochastic reactions takes the form of random fluctuations in concentration of the minor species. We demonstrate that advection associated with the hydrodynamics of a collapsing cavity leads to highly inhomogeneous concentration of solutes. In turn these inhomogeneities in concentration may lead to significant increase in concentration-dependent reaction rates and can result in a local enhancement in the production of minor species.

AB Significant advances have recently been made to develop optically interrogated microsensor based chemical sensors with specific application to hydrogen vapor sensing and leak detection in the hydrogen economy. We have developed functionalized polymer-film and palladium/silver alloy coated microcantilever arrays with nanomechanical sensing for this application. The uniqueness of this approach is in the use of independent component analysis (ICA) and the classification techniques of neural networks to analyze the signals produced by an array of microcantilever sensors. This analysis identifies and quantifies the amount of hydrogen and other trace gases physisorbed on the arrays. Selectivity is achieved by using arrays of functionalized sensors with a moderate distribution of specificity among the sensing elements. The device consists of an array of beam-shaped transducers with molecular recognition phases (MRPs) applied to one surface of the transducers. Bending moments on the individual transducers can be detected by illuminating them with a laser or an LED and then reading the reflected light with an optical position sensitive detector (PSD) such as a CCD. Judicious selection of MRPs for the array provides multiple isolated interaction surfaces for sensing the environment. When a particular chemical agent binds to a transducer, the effective surface stresses of its modified and uncoated sides change unequally and the transducer begins to bend. The extent of bending depends upon the specific interactions between the microcantilever's MRP and the analyte. Thus, the readout of a multi-MRP array is a complex multidimensional signal that can be analyzed to deconvolve a multicomponent gas mixture. The use of this sensing and analysis technique in unattended networked arrays of sensors for various monitoring and surveillance applications is discussed.

AB We have developed algorithms to automatically learn a detection map of a deployed sensor field for a virtual presence and extended defense (VPED) system without apriori knowledge of the local terrain. The VPED system is an unattended network of sensor pods, with each pod containing acoustic and seismic sensors. Each pod has the ability to detect and classify moving targets at a limited range. By using a network of pods we can form a virtual perimeter with each pod responsible for a certain section of the perimeter. The site's geography and soil conditions can affect the detection performance of the pods. Thus, a network in the field may not have the same performance as a network designed in the lab. To solve this problem we automatically estimate a network's detection performance as it is being installed at a site by a mobile deployment unit (MDU). The MDU will wear a GPS unit, so the system not only knows when it can detect the MDU, but also the MDU's location. In this paper, we demonstrate how to handle anisotropic sensor-configurations, geography, and soil conditions.

AB Damage to DNA, in the form of cyclobutane pyrimidine dimers (CPD), may occur in soybean (Glycine max (L.) Men) plants when they are exposed to increasing levels of ultraviolet-B (UV-B) radiation. Flavonoids and other phenolics accumulate in the epidermal layer of leaves and may provide protection for sensitive tissues including DNA molecules. We evaluated the steady state levels of accumulated damage and the protection afforded by flavonoids in two soybean isolines: Clark producing high levels of flavonoids, and Clark-magenta producing extremely low flavonoid levels. Both cultivars were grown in the field under ambient and supplemental UV-B radiation. Leaf tissue was harvested in a diurnal sequence, and the samples were analyzed. Two methods of analysis were used in order to develop a common reference point between the two. In one method, DNA was isolated and treated with UV endonuclease, and the DNA fragments were separated using unidirectional pulsed field electrophoresis and quantified through electronic imaging. In the alternate method, a western blotting procedure, immobilized DNA was reacted with monoclonal antibodies specific to CPD DNA damage. Results were similar in both techniques and show lesion frequency to be low in both isolines. However significant differences were found between cultivars, UV treatments, time of day collected, and levels of PAR. The average level of dimers per megabase for the isoline Clark was similar to 4 (with or without supplemental UV), and for Clark-magenta, similar to 4 for samples with no supplemental UV and similar to 6 for those exposed to supplemental UV radiation. Diurnally, dimer levels were frequently higher in the Clark-magenta isoline, especially when exposed to supplemental UV-B. Both isolines appear to be either well-protected from DNA damage, or repair is efficient enough to minimize biologically significant accumulation of DNA damage. This suggests that protection mechanisms, other than flavonoids alone, contribute to maintenance of DNA integrity in soybean.

AB Animal models carrying mutations in the hairless (Hr) gene provide a rich resource for study of hair follicle biology. A spontaneous mouse mutant with a phenotype strikingly similar to rhino mutants of Hr arose spontaneously in the mouse facility at Oak Ridge National Laboratory. Sequence analysis of Hr in these mutants uncovered a nonsense mutation in exon 12, designated as Hr(rh-R) (rhino, Oak Ridge). The mutation led to significant reduction in Hr mRNA levels, predicted to be due to nonsense-mediated decay. Histological analysis indicated dilated hair follicle infundibula at 14 days of age that rapidly became filled with cornified material. Microarray analyses revealed that expression levels of many genes involved in keratinocyte differentiation, epidermal regeneration, and wound healing were significantly upregulated before morphological detection of the phenotype, suggesting their role in onset of the Hr(rh-R) phenotype. Identification of this new Hr allele and the underlying molecular alterations allows further understanding of the role of Hr in hair follicle biology.

AB Recent results from Jefferson Lab (JLab) on the extraction of single- and double-polarization observables in both the 1 pi- and 2 pi-channel show their high sensitivity to resonant production amplitudes and therefore their importance for the extraction of resonance parameters. The CEBAF Large Acceptance Spectrometer (CLAS) has access to the baryon resonance (N*) form factors at high Q(2), which is advantageous for the study of the dynamical properties of nucleon resonances. In anticipation of the 12 GeV energy upgrade to JLab, our group plans to extract the electromagnetic transition form factors (electrocouplings) for many well-established excited nucleon states in the unexplored domain of Q(2) > 5 GeV2. The expected data on resonance electrocouplings will allow us to systematically explore how in the strong interaction regime of QCD bare quarks are dressed with gluons and how quark cores of the various N* states emerge from QCD.

AB The search for an electric dipole moment of the neutron tests physics beyond the Standard Model such as new sources of CP-violation and Supersymmetry. The nEDM experiment aims to improve the sensitivity on the current limit of the electric dipole moment of the neutron to <10(-27) e.cm. The experiment will use a flux of Ultra Cold Neutrons (UCNs) produced and stored in a bath of superfluid He-II. A change in precession frequency is expected for a non-zero EDM when an electric field is applied parallel and antiparallel to a magnetic field across the neutron storage cell. A dominant parameter in terms of reducing the statistical uncertainty of this measurement is the strength of the applied electric field. An experiment to measure if superfluid He-II can sustain up to 50 kV/cm for a volume and electrode spacings comparable to the nEDM experiment has been constructed at Los Alamos National Laboratory. It consists in a large-area parallel plate capacitor immersed in a 200 liter central volume inside a suitable cryostat that in turn is connected to a dilution refrigerator unit. A description of test runs and the status of the experiment is presented.

AB Neutron induced fission cross sections of several isotopes have been measured at the CERN n_TOF spallation neutron facility. Between them some measurements involve isotopes ((233)u, (241)-Am, Am-243, (245)cm) relevant for applications to nuclear technologies. The n_TOF facility delivers neutrons with high instantaneous flux and in a wide energy range, from thermal up to 250 MeV. The experimental apparatus consists of an ionization chamber that discriminates fission fragments and a particles coming from natural radioactivity of the samples. All the measurements were performed referring to the standard cross section of U-235.

DE Dense correspondences; Pose estimation; Scene reconstruction; Bundle
adjustment; Resolution pyramid; Error analysis
AB A novel method to detect and correct inaccuracies in a set of unconstrained dense correspondences between two images is presented. Starting with a robust, general-purpose dense correspondence algorithm, an initial pose estimate and dense 3D scene reconstruction are obtained and bundle-adjusted. Reprojection errors are then computed for each correspondence pair, which is used as a metric to distinguish high and low-error correspondences. An affine neighborhood-based coarse-to-fine iterative search algorithm is then applied only on the high-error correspondences to correct their positions. Such an error detection and correction mechanism is novel for unconstrained dense correspondences, for example not obtained through epipolar geometry-based guided matching. Results indicate that correspondences in regions With issues such as occlusions, repetitive patterns and moving objects can be identified and corrected, such that a more accurate set of dense correspondences results from the feedback-based process, as proven by more accurate pose and structure estimates.

AB Ship detection from satellite imagery is something that has great utility in various communities. Knowing where ships are and their types provides useful intelligence information. However, detecting and recognizing ships is a difficult problem. Existing techniques suffer from too many false-alarms. We describe approaches we have taken in trying to build ship detection algorithms that have reduced false alarms. Our approach uses a version of the grayscale morphological Hit-or-Miss transform. While this is well known and used in its standard form, we use a version in which we use a rank-order selection for the dilation and erosion parts of the transform, instead of the standard maximum and minimum operators. This provides some slack in the fitting that the algorithm employs and provides a method for tuning the algorithm's performance for particular detection problems. We describe our algorithms, show the effect of the rank-order parameter on the algorithm's performance and illustrate the use of this approach for real ship detection problems with panchromatic satellite imagery.

AB Recent developments in sequencing technology have created a flood of new data on human genetic variation, and this data has yielded new insights into human population structure. Here we review what both early and more recent studies have taught us about human population structure and history. Early studies showed that most human genetic variation occurs within populations rather than between them, and that genetically related populations often cluster geographically. Recent Studies based on much larger data sets have recapitulated these observations, but have also demonstrated that high-density genotyping allows individuals to be reliably assigned to their population of origin. In fact, for admixed individuals, even the ancestry Of Particular genomic regions can often be reliably inferred. Recent studies have also offered detailed information about the composition of specific populations from around the world, revealing how history has shaped their genetic makeup. We also briefly review quantitative models of human genetic history, including the role natural selection has played in shaping human genetic variation.

AB Computer simulations of (110) rutile surface interacting with aqueous solution were carried out as part of a multidisciplinary team effort to characterize metal-oxide interfaces. The purpose of these simulations is twofold (i) provide results which can be linked with experimental observations and help in interpreting them, (ii) advance the methodology of computer simulations and extend their possibilities in determining new properties. So far, we were able to provide information from simulation on the structure and space-dependent diffusivity of water and ions at the interface, strength of hydrogen bonds at the interface, space dependent viscosity of water and the temperature effect on these properties. In this work we have identified the temperature and surface charge (related to pH of solution) effect on the adsorption of Rb+ and Na+ ions. While the temperature effect on Rb+ adsorption is weak, increasing temperature leads to shift of Na+ ions closer to the surface.

ID FLUID; CO2
AB A novel concept for enhanced geothermal systems (EGS) was proposed recently that would use supercritical CO2 (sc-CO2) instead of water as heat transmission fluid. Modeling studies have indicated that sc-CO2 has very favorable properties (low viscosity and large expansivity) for heat extraction and transmission to the land surface. The present paper considers the CO2-rich geothermal system at Mt. Amiata in Tuscany (Central Italy) as a potential analogue for studying geochemical changes in the peripheral and outer zones of an EGS operated with sc-CO2 (CO2-EGS). Field observations of mineral alteration and fluid chemistry are used to constrain reactive chemical transport simulations, and to obtain insights into rock-fluid interactions in a CO2-EGS system.

AB Geochemical results from Multi-laboratory Frio Brine Pilot I-II (Texas) proved powerful in: 1-Tracking the flow of CO2 into the Frio sandstones; 2-showing that some CO2 was detected in the overlying B sandstone that is separated by 15 m of shale; and 3-showing mobilization of metals, organics, and major changes in chemical and isotopic compositions of brine, including calculated pH lowering (6.3-3.0) and increases in alkalinity. Geochemical modeling, chemical data and Fe isotopes indicate rapid dissolution of minerals, especially calcite and Fe-oxyhydroxides, and that portions of metal increases were caused by corrosion of well pipe. Similar isotopic and chemical changes were also observed in samples obtained from shallow (1.5 m) potable groundwater following CO2 injection in the ZERT site, Montana. Results from both the deep and shallow tests show highly sensitive chemical and isotopic tracers that can monitor injection performance and provide early detection of CO2 and brine leakages at CO2 injection sites.

AB CO2 sequestration in deep subsurface reservoirs must ensure the protection of overlying potable groundwater aquifers. Questions exist whether potable water could become contaminated by leakage and upward migration of CO2, possibly containing co-injected H2S and/or organic compounds mobilized at depth by supercritical CO2. Some recent investigations on these various issues are summarized. The potential increase in the concentrations of trace metals in groundwater due to the release of CO2 is discussed. Simulations of benzene mobilization by supercritical CO2 and the effect of co-injected H2S are also reported. CO2 dissolution into groundwater leads to a pH decrease and an increase in dissolved carbonate content, which can trigger the dissolution/precipitation of minerals and sorption/exchange reactions, possibly mobilizing trace elements. Modeling results show that the leakage of co-injected H2S into groundwater could exacerbate potential impacts and benzene potentially present at depth could be dissolved by supercritical CO2 and mobilized to shallower groundwater.

DE REST; Resource-Oriented; Process-Intensive; Business Process
AB REpresentational State Transfer (REST) is the architecture style behind the World Wide Web (WWW), allowing for many desirable quality attributes such as adaptability and interoperability. However, as many process-intensive Web information systems do not make use of REST, they often do not achieve these qualities. This paper addresses this issue by proposing RESTful Business Processes (RESTfulBP), an architectural style that adapts REST principles to Web-based business processes. RESTfulBP views processes and activities as transferrable resources by representing them as process fragments associated with a set of standard operations. Distributed process fragments interoperate by adhering to these operations and exchanging process information. The process information contains basic workflow patterns that are used for dynamic process coordination at runtime. We validate our approach through an industry case study.

ID DESIGN
AB Wind turbine structures need to be designed with careful consideration of the fatigue strength and loading on critical load-bearing components. Each material in the various components of a wind turbine will potentially use different damage models to map the cyclic fatigue loadings into progressive deterioration of the material. In most cases, linear damage models using a Miner's Rule type approach are prevalent in design. The loadings of a particular turbine can be described as a function of the inflow conditions, which are considered to be weakly stationary for short periods, typically 10 minutes. These characteristic response statistics of the turbine are aggregated into a long-term distribution of loads using the theory of random variables and probability distribution functions. The long-term distribution is applied to the damage model to produce an estimate of fatigue lifetime. The design criteria require that the estimated stresses be amplified by safety factors to account for unfavourable deviations of action and material properties, as well as modeling uncertainties.

AB Top-off operations is a quasi-continuous injection mode that increases the flux and brightness of a synchrotron source and improves thermal stability of optical components by maintaining a constant current in the storage ring. Although the increased and constant flux is advantageous for FTIR measurements, the frequent injections (about one every 30 seconds in the ALS case) introduce artifacts into the spectrum by creating spikes in the interferogram data. These spikes are caused by brief beam motion during the injection event. Here, we describe our efforts to minimize the effects of top-off generated interferogram spikes on several FTIR spectrometers. They include using a fast feedback mirror system to correct for beam motion and a gating signal to inhibit interferogram collection during a top-off injection.

AB Standard commercial infrared microscopes operating in reflection mode use a mirror to direct the reflected light from the sample to the detector. This mirror blocks about half of the incident light, however, and thus degrades the spatial resolution by reducing the numerical aperture of the objective. Here, we replace the mirror with a 50% beamsplitter to allow full illumination of the objective and retain a way to direct the reflected light to the detector. The improved spatial resolution is demonstrated using a microscope coupled to a synchrotron source.

AB Extensive neuroscience research on the hippocampus has identified its crucial role in memory formation and recall. Specifically, associative binding of the components comprising an episodic memory has been identified as one of the functions performed by the hippocampus. Based upon neuroanatomical function we have devised a computational cortical-hippocampal architecture using variants of adaptive resonance theory (ART) artificial neural networks. This computational model is capable of processing multi-modal sensory inputs and capturing qualitative memory phenomena such as auto-association and recall. Model performance is assessed both qualitatively and quantitatively. From a quantitative standpoint, we have applied the mathematics of information theory to quantify the similarity between recalled images yielded by the model and the unaltered original inputs. Thus in this paper we present a neurologically plausible computational architecture as well as a quantitative assessment of model performance.

AB For the Domestic Nuclear Detection Office's Rail Test Center (DNDO's RTC), port operation knowledge with flexible collection tools and technique are essential in both technology testing design and implementation intended for live operational settings. Increased contextual data, flexibility in procedures, and rapid availability and targeted communication of information are keys to addressing the challenges of optimization, validation, analysis, and decision-making in data collection within a live operational setting for technology evaluation. These collection and communication concepts need to be integrated into technology testing strategies, designs, data collection methods, validation, and analysis processes. A modified data collection technique is proposed for providing information within the operational context to improve communication and understanding through a two-phased live operation test method.

AB In this study, we apply the methods of engineering risk analysis to understand the structure of a nuclear proliferation network in order to defeat it. These methods are typically applied to engineering systems in order to assess the weaknesses in a system and determine the most cost-effective way to improve that system; instead, this analysis turns risk analysis on its head, as we seek to understand the uncertainties, dependencies, and redundancies that exist in the system in order to induce failure (or degradation).
In order to accomplish this goal, our team modeled the A.Q. Khan network as a supply chain in order to determine its weak points and possible ways to defeat the network. We then attempted to generalize our findings in order to apply them to future networks. Our report is based completely on our analysis of open source information.

AB Understanding the principal physical and chemical factors that govern or limit cell performance is critical for underpinning the development of next-generation sensitized solar cells. Recent studies of dye-sensitized solar cells (DSSCs) covering nanoporous (pore diameter <100 nm) one-dimensional TiO2 nanostructured arrays and molecular voltage enhancers are discussed. Films constructed of oriented one-dimensional nanostructures, such as nanotube arrays, which are aligned perpendicularly to the charge-collecting substrate, could potentially improve the charge-collection efficiency by promoting faster transport and/or slower recombination. The extent to which transport or recombination could be affected by an oriented architecture is expected to depend on the influence of other mechanistic factors, such as the density and location of defects, crystallinity, and film uniformity. Orientational disorder within the nanotube array could also influence the transport and recombination kinetics. Such architectural disorder in titanium dioxide films is shown to have a strong influence on the transport, recombination, and light-harvesting properties of DSSCs. The mechanism by which molecular adsorbents alter the photovoltage of DSSCs is dependent on the properties of the adsorbent. In principle, an adsorbent could affect the photovoltage by either altering the recombination rate of photoelectrons in TiO2 with oxidized redox species in the electrolyte or inducing band-edge movement. The net effect of altering the band positions and recombination kinetics can either improve or diminish cell performance. The mechanisms by which several molecular adsorbents increase the photovoltage of DSSCs are discussed.

AB The Large Area Picosecond Photodetectors described in this contribution incorporate a photocathode and a borosilicate glass capillary Micro-Channel Plate (MCP) pair functionalised by atomic layer deposition (ALD) of separate resistive and secondary emission materials. Initial testing with matched pairs of small glass capillary test disks has demonstrated gains of the order of 10(5)-10(6). Compared to other fast imaging devices, these photodetectors are expected to provide timing resolutions in the 10-100 ps range, and two-dimension position in the sub-millimeter range. If daisy chained, large detectors read at both ends with fast digitising integrated electronics providing zero-suppressed calibrated data should be produced at relatively low cost in large quantities.

AB We present a multi-wavelength study on a z similar to 0.9, CI 1257+4738. The cluster CI 1257+4738 was found by comparing a ROSAT image with red ground based images, taken to determine if the red galaxies were young dusty ones or old early type galaxies. This adds another cluster to the handful of clusters with z larger than about 0.9. Each one provides new insights as to the relationship between the evolution of galaxies and the ICM. We acquired Chandra, XMM-Newton, Spitzer IRAC plus MIPS 24 data to study this relationship between galaxies and the ICM. The Chandra plus Spitzer and ground-based data gave us the unique opportunity to find candidate galaxies and AGNs that could be at redshifts from 3 up to as high as 10.

AB Motivated by the need for megapixel high definition trace element imaging to capture intricate detail in natural material, together with faster acquisition and improved counting statistics in elemental imaging, a large energy-dispersive detector array called Maia has been developed by CSIRO and BNL for SXRF imaging on the XFM beamline at the Australian Synchrotron. A 96 detector prototype demonstrated the capacity of the system for real-time deconvolution of complex spectral data using an embedded implementation of the Dynamic Analysis method and acquiring highly detailed images up to 77M pixels spanning large areas of complex mineral sample sections.

AB The new generation of neutron scattering instruments being built are higher resolution and produce one or more orders of magnitude larger data than the previous generation of instruments. For instance, we have grown out of being able to perform some important tasks with our laptops. The data sizes are too big and the computational time would be too long. These large datasets can be problematic as facility users now begin to struggle with many of the same issues faced by more established computing communities. These issues include data access, management, and movement, data format standards, distributed computing, and collaboration with others. The Neutron Science Portal has been designed, and implemented to provide users with an easy-to-use interface for managing and processing data, while also keeping an eye on meeting modern computer security requirements that are currently being imposed on institutions. Users can browse or search for data which they are allowed to see, run data reduction and analysis applications, perform sample activation calculations and perform McStas simulations. Collaboration is facilitated by providing users a read/writeable common area, shared across all experiment team members. The portal currently has over 370 registered users; almost 7TB of experiment and user data, approximately 1,000,000 files cataloged, and had almost 10,000 unique visits last year. Future directions for enhancing portal robustness include examining how to mirror data and portal services, better facilitation of collaborations via virtual organizations, enhancing disconnected service via "thick client" applications, and better inter-facility connectivity to support cross-cutting research.

AB We discuss the construction of a new SAXS/WAXS beamline at the Advanced Light Source at Lawrence Berkeley Laboratory. The beamline is equipped with a multilayer monochromator in order to obtain a high X-ray flux. The detrimental effects that the increased bandwidth transmitted by this monochromator could have on the data quality of the SAXS and WAXS patterns is shown to be negligible for the experimental program intended to be operated on this beamline.

AB Considerable progress has been achieved recently in the experimental investigation of quadrupole-collective isovector excitations in the valence shell, the so called mixed-symmetry states (MSSs), in the mass A approximate to 130 region. This is due to a new experimental technique for study MSSs which is based on the observation of low-multiplicity gamma-ray events from inverse kinematics Coulomb excitation with the large 4 pi spectrometer, such as Gammasphere. The obtained experimental information for the MSSs of stable N = 80 isotones indicates that for low-collective vibrational nuclei the underlying single-particle structure can be the most important factor for preserving or fragmenting the MSSs through the mechanism of shell stabilization. The evolution of the MSSs from Xe-134 to Ce-138 is also used to determine the local strength of the proton-neutron interaction derived for first time from states with symmetric and antisymmetric nature.

AB Neutron transfer (d,p) reactions have been measured with rare isotope beams of (132)sn, (130)sn and Te-134 accelerated to approximate to 4.5 MeV/u interacting with CD2 targets. Reaction protons were detected in an early implementation of the ORRUBA array of position-sensitive silicon strip detectors. Neutron excitations in the 2f(7/2), 3p(3/2), 3p(1/2) and 2f(5/2) orbitals were populated.

AB The polar intermetallic phases A(2)AuBi (A = Na (I), K (II)), and K2AuSb (III) were obtained by direct reaction of the elements at elevated temperatures in niobium ampoules. The three isotypic compounds extend the prominent A(2)MP(n) (M = transition metal; P-n = group 15) structure family. Single-crystal X-ray diffraction experiments show that these phases (I / II / III) crystallize in the orthorlionibic space group Cnicin (No. 63), with a = 9.447(2) / 10.632(2) / 10.450(2) angstrom; b = 7.700(2) 7.918(2) / 7.857(2) angstrom; c = 5.849(1) / 6.597(1) / 6.501 (1) angstrom; V = 425.4(2) / 555.4(2) / 533.8(2) angstrom(3), respectively, and Z = 4 The simple structures, which contain zigzag chains of linear two-bonded gold atoms and acute angles (64 to 76 degrees) at two-bonded antimony or bismuth, can readily be rationalized with the Zintl-Klemm concept.

A phase transition to a high-pressure polymorph II of lead carbonate was observed at a pressure of approximately p(c) = 8.7 GPa. Thereby, the symmetry is reduced from orthorhombic Pmcn to monoclinic P12(1)/c1.

Inhomogeneities were measured quantitatively and attributed to limitations of the manufacturing process. 3-dimensional image reconstructions were performed by using our Error-Reduction and Hybrid-Input-Output iterative algorithms. These revealed images of the focussed X-ray beam passing through the active layer of the wafer.

AB Time-dependent density functional theory is one of the most widely used methods for the calculation of excited states of large molecules. However, it exhibits substantial problems with charge-transfer excited states when conventional exchange-correlation functionals are employed. Here, we introduce an additive long-range potential that can, in principle, be directly employed with any existing local, GGA or hybrid-functional, without re-fitting of the original functionals. The additive potential shifts the excitation energies to higher values and corrects for the wrong asymptotic behavior of their potential energy surfaces with respect to charge-separating coordinates. First examples of its successful application are shown.

AB Background: Interventional medical devices based on thermally responsive shape memory polymer (SMP) are under development to treat stroke victims. The goals of these catheter-delivered devices include re-establishing blood flow in occluded arteries and preventing aneurysm rupture. Because these devices alter the hemodynamics and dissipate thermal energy during the therapeutic procedure, a first step in the device development process is to investigate fluid velocity and temperature changes following device deployment.
Methods: A laser-heated SMP foam device was deployed in a simplified in vitro vascular model. Magnetic resonance imaging (MRI) techniques were used to assess the fluid dynamics and thermal changes associated with device deployment.
Results: Spatial maps of the steady-state fluid velocity and temperature change inside and outside the laser-heated SMP foam device were acquired.
Conclusions: Though non-physiological conditions were used in this initial study, the utility of MRI in the development of a thermally-activated SMP foam device has been demonstrated.

AB There is a debate as to the identity of the fluctuations which constitute the relatively high-frequency plasma turbulence observed in the solar wind. One school holds that these modes are kinetic Alfven waves, whereas another opinion is that they are whistler modes. Here linear kinetic theory for electromagnetic fluctuations in homogeneous, collisionless, magnetized plasmas is used to compute two dimensionless transport ratios, the electron compressibility C(e) and the magnetic compressibility C(parallel to) for these two modes. The former is a measure of the amplitude of density fluctuations, and the latter indicates the relative energy in magnetic fluctuations in the component parallel to the background magnetic field B(o). For beta(e) << 1, [C(parallel to)](Alfven) << [C(parallel to)](whistler), and the latter quantity is of order 0.5 at whistler propagation strongly oblique to B(o). Such values of C(parallel to) are sometimes measured at relatively high frequencies and beta(e) << 1 in the solar wind; thus, it is concluded that such observations correspond to whistler mode turbulence. But other solar wind observations indicate that kinetic Alfven fluctuations also contribute to relatively high-frequency solar wind turbulence.

AB Mass-analyzed threshold ionization (MATI) spectroscopy using synchrotron radiation (Advanced Light Source, Lawrence Berkeley National Laboratory) has been performed for Ar, N(2), O(2), N(2)O, H(2)O, C(2)H(2) and C(6)H(6). MATI allows for a better determination of ionization energies compared to those derived from photoionization efficiency curves traditionally used in synchrotron photoionization mass spectrometry. The separation of the long-lived Rydberg state from the directly formed prompt ion, essential for a meaningful MATI spectrum, has been accomplished by employing an arrangement of ion optics coupled to unique electric field pulsing schemes. For Ar, a number of resolved bands below the ionization energy are observed, and these are ascribed to high-n,l Rydberg states prepared in the MATI scheme. The first vibrational state resolved MATI spectra of N(2) and O(2) are reported, and spectral characteristics are discussed in comparison with previously reported threshold photoelectron spectroscopic studies. Although MATI pet-formed with synchrotron radiation is intrinsically less sensitive compared to laser-based sources, this work demonstrates that MATI spectroscopy performed with widely tunable vacuum ultraviolet (VUV) radiation is a complementary technique for studying the ionization spectroscopy of polyatomic molecules.

AB The high-resolution photoelectron spectrum of KrO- was obtained using slow electron velocity-map imaging (SEVI). The SEVI spectrum reveals numerous vibronic transitions between multiple electronic states of KrO- and KrO, both of which are open-shell species. Detailed assignments are made by comparison with theoretical simulations based on high level ab initio calculations and an atoms-in-molecule model that accounts for spin-orbit coupling in the anion and neutral. Several KrO- and KrO vibrational frequencies and excited-state term energies are accurately determined from the analysis of the experimental spectra and are found to be in good agreement with the calculated values.

AB We report the first measured differential cross sections for rotationally inelastic collisions between ND3 and Ne, obtained using velocity-mapped ion imaging. In these experiments, ND3 molecules initially in the J = 0, K = 0 and J = 1, K = 1 quantum states collide with Ne atoms at a center-of-mass collision energy of 65 meV, leading to rotational excitation of ND3. Differential cross sections are then determined from images of the rotationally excited scattered molecules using an iterative extraction method. These measurements complement and compare well with previous measurements of differential cross sections for the ammonia-rare gas system (Meyer, H. J. Chem. Phys. 1994, 101, 6697.; Meyer, H. J. Phys. Chem. 1995, 99, 1101.) and are also relevant to the production of cold ND3 molecules by crossed-beam scattering (Kay, J. J.; van de Meerakker, S. Y. T.; Strecker, K. E.; Chandler, D. W.

AB This article introduces the concept of intrinsic entropy, S, of a molecular collision. Defined in rigorously quantum mechanical terms as the von Neumann entropy of the intrinsic density matrices of reagents and products, the intrinsic entropy is a dimensionless number in the 0 <= S <= 1 range. Its limits are associated with situations where the collision cross section is due to a single combination of reagent and product polarizations (S = 0) or where there is absolutely no selectivity with respect to the molecular polarizations (S = 1). The usefulness of the intrinsic entropy as a quantifier of the sensitivity of a molecular collision to molecular polarizations is demonstrated with examples for the benchmark H + D-2 reaction.

AB Conformational flexibility of proteins has been linked to their designated functions. Slow conformational fluctuations occurring at the microsecond to millisecond time scale, in particular, have recently attracted considerable interest in connection to the mechanism of enzyme catalysis. Computational methods are providing valuable insights into the connection between protein structure, flexibility, and function. In this report, we present Studies oil identification and characterization of microsecond flexibility of ubiquitin, based on quasi-harmonic analysis (QHA) and normal-mode analysis (NMA). The results indicate that the slowest 10 QHA modes, Computed from the 0.5 us molecular dynamics ensemble, contribute over 78% of all motions. The identified slow movements show over 75% similarity with the conformational fluctuations observed in nuclear magnetic resonance ensemble and also agree with displacements in the set of X-ray structures. The slowest modes show high flexibility in the beta 1-beta 2, alpha 1-beta 3, and beta 3-beta 4 loop regions, with functional implications in the mechanism of binding other proteins. NMA Of ubiquitin structures was not able to reproduce the long time scale fluctuations, as they were found to strongly depend on the reference structures. Further, conformational fluctuations Coupled to the cis/trans isomerization reaction catalyzed by the enzyme cyclophilin A (CypA), occurring at the microsecond to millisecond time scale, have also been identified and characterized oil the basis of QHA of conformations sampled along the reaction pathway. The results indicate that QHA covers the same conformational landscape as the experimentally observed CypA flexibility. Overall, the identified slow conformational fluctuations ill ubiquitin and CypA indicate that the intrinsic flexibility of these proteins is closely linked to their designated functions.

AB The effect of manganese addition to the Co-MCM-41 catalyst on the synthesis of single wall carbon nanotubes (SWNT) by CO disproportionation was characterized. The ratio between the two metals in the MCM-41 framework was varied, and its effect on the resultant SWNT distribution was studied and compared with the results obtained for the monometallic Co-MCM-41 catalyst. Methods including temperature-programmed reduction, X-ray absorption fine structure, thermogravimetric analysis, TEM imaging, and Raman and fluorescence spectroscopy were employed to characterize the behavior of the catalysts under the SWNT synthesis conditions and the diameter and Structure distribution of the resultant nanotubes. We found that addition of Mn to the Co-MCM-41 catalyst promotes the growth of SWNT, leading to synthesis of high yield, small diameter SWNT. Manganese does not act in the nucleation of SWNT but acts as an anchoring site for cobalt particles formed during the synthesis process as shown by X-ray absorption.

AB To reduce fuel cell cost, durable and inexpensive electrode catalysts need to be developed to replace precious metal materials, particularly for the electrocatalytic oxygen reduction at cathodes. In this study, we explored the structure and the energetics of Fe-xN (x = 2,4) incorporated into carbon nanotubes and graphene using density functional theory to show that these structures are more stable than iron atoms on nanotubes and that pyridinic structures of Fe-4N are more favorable than pyrrolic structures. EXAFS spectra simulated from the optimized structures show good agreement with results of measurements obtained oil arrays of aligned nanotubes doped with iron and nitrogen, which have demonstrated activity toward oxygen-reduction reactions.

AB A density functional theory Study of the decomposition of methanol on subnanometer palladium Clusters (primarily Pd-4) is presented. Methanol dehydrogenation through C-H bond breaking to form hydroxymethyl (CH2OH) as the initial step, followed by steps involving formation of hydroxymethylene (CHOH), formyl (CHO), and carbon monoxide (CO), is found to be the most favorable reaction pathway. A competing dehydrogenation pathway with O-H bond breaking as the first step, followed by formation of methoxy (CH3O) and formaldehyde (CH2O), is slightly less favorable. In contrast, pathways involving C-O bond cleavage are much less energetically favorable, and no feasible pathways involving C-O bond formation to yield dimethyl ether (CH3OCH3) are found. Comparisons of the results are made with methanol decomposition products adsorbed on more extended Pd Surfaces; all reaction intermediates are found to bind slightly more strongly to the clusters than to the surfaces.

ID CONJUGATED MOLECULES; ELECTRONIC-STRUCTURE; NANOTUBES; MACROCYCLES;
EXCITATIONS; STATES; BELTS
AB The electronic structure and size-scaling of optoelectronic properties in cycloparaphenylene carbon nanorings are investigated using time-dependent density functional theory (TDDFT). The TDDFT calculations on these molecular nanostructures indicate that the lowest excitation energy surprisingly becomes larger as the carbon nanoring size is increased, in contradiction with typical quantum confinement effects. In order to understand their unusual electronic properties, I performed an extensive investigation of excitonic effects by analyzing electron-hole transition density matrices and exciton binding energies as a function of size in these nanoring systems. The transition density matrices allow a global view of electronic coherence during an electronic excitation, and the exciton binding energies give a quantitative measure of electron-hole interaction energies in the nanorings. Based oil overall trends in exciton binding energies and their spatial delocalization, I find that excitonic effects play a vital role in understanding the unique photoinduced dynamics in these carbon nanoring systems.

AB Synchrotron-based in Situ time-resolved X-ray diffraction and X-ray absorption spectroscopy were used to study pure ceria and Pd-loaded ceria nanotubes and nanorods (1D-ceria) as catalysts for the water-gas shift (WGS) reaction. While bulk ceria is very poor as WGS catalysts, pure I D-ceria displayed catalytic activity at a temperature as low as 300 degrees C. The reduction of the pure ID-ceria in pure hydrogen started at 150 degrees C, which is a much lower temperature than those previously reported for the reduction of 3D ceria nanoparticles. This low reduction temperature reflects the novel morphology of the oxide systems and may be responsible for the low-temperature WGS catalytic activity seen for the 1D-ceria. Pd-loaded 1D ceria displayed significant WGS activity starting at 200 degrees C. During pretreatment in H(2), the ceria lattice parameter increased significantly around 60 degrees C, which indicates that Pd-oxygen interactions may facilitate the reduction of Pd-loaded 1D-ceria. Pd and ceria both participate in the formation of the active sites for the catalytic reactions. The low-temperature hydrogen pretreatment results in higher WGS activity for Pd-loaded 1D-ceria.

ID GLOBAL ANALYSIS; LEPTON CHARGE; OSCILLATIONS; DETECTOR
AB This Letter reports on a search for nu(mu)->nu(e) transitions by the MINOS experiment based on a 3.14x10(20) protons-on-target exposure in the Fermilab NuMI beam. We observe 35 events in the Far Detector with a background of 27 +/- 5(stat)+/- 2(syst) events predicted by the measurements in the Near Detector. If interpreted in terms of nu(mu)->nu(e) oscillations, this 1.5 sigma excess of events is consistent with sin(2)(2 theta(13)) comparable to the CHOOZ limit when |Delta m(2)|=2.43x10(-3) eV(2) and sin(2)(2 theta(23))=1.0 are assumed.

DT Article
ID QUARK-GLUON PLASMA; FLUCTUATIONS; COLLABORATION; PERSPECTIVE; COLLISIONS
AB The third moments of conserved charges, the baryon and electric charge numbers, and energy, as well as their mixed moments, carry more information on the state around the QCD phase boundary than previously proposed fluctuation observables and higher order moments. In particular, their signs give plenty of information on the location of the state created in relativistic heavy ion collisions in the temperature and baryon chemical potential plane. We demonstrate this with an effective model.

DT Article
AB A dilaton could be the dominant messenger between standard model fields and dark matter. The measured dark matter relic abundance relates the dark matter mass and spin to the conformal breaking scale. The dark matter-nucleon spin-independent cross section is predicted in terms of the dilaton mass. We compute the current constraints on the dilaton from LEP and Tevatron experiments, and the gamma-ray signal from dark matter annihilation to dilatons that could be observed by Fermi Large Area Telescope.

TI Highly Excited and Exotic Meson Spectrum from Dynamical Lattice QCD
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
AB Using a new quark-field construction algorithm and a large variational basis of operators, we extract a highly excited isovector meson spectrum on dynamical anisotropic lattices. We show how carefully constructed operators can be used to reliably identify the continuum spin of extracted states, overcoming the reduced cubic symmetry of the lattice. Using this method we extract, with confidence, excited states, states with exotic quantum numbers (0(+-), 1(-+), and 2(+-)), and states of high spin, including, for the first time in lattice QCD, spin-four states.

AB We show by means of ab initio calculations that the organic molecular crystal TTF-CA is multiferroic: it has an instability to develop spontaneously both ferroelectric and magnetic ordering. Ferroelectricity is driven by a Peierls transition of the TTF-CA in its ionic state. Subsequent antiferromagnetic ordering strongly enhances the opposing electronic contribution to the polarization. It is so large that it switches the direction of the total ferroelectric moment. Within an extended Hubbard model, we capture the essence of the electronic interactions in TTF-CA, confirm the presence of a multiferroic groundstate, and clarify how this state develops microscopically.

TI Ferro-Orbital Order and Strong Magnetic Anisotropy in the Parent
Compounds of Iron-Pnictide Superconductors
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
AB The puzzling nature of magnetic and lattice phase transitions of iron pnictides is investigated via a first-principles Wannier function analysis of representative parent compound LaOFeAs. A rare ferro-orbital ordering is found to give rise to the recently observed highly anisotropic magnetic coupling, and drive both phase transitions-without resorting to widely employed frustration or nesting picture. The revealed necessity of the additional orbital physics leads to a correlated electronic structure fundamentally distinct from that of the cuprates. In particular, the strong coupling to the magnons advocates active roles of light orbitons in spin dynamics and electron pairing in iron pnictides.

AB Methane gas hydrates, crystalline inclusion compounds formed from methane and water, are found in marine continental margin and permafrost sediments worldwide. This article reviews the current understanding of phenomena involved in gas hydrate formation and the physical properties of hydrate-bearing sediments. Formation phenomena include pore-scale habit, solubility, spatial variability, and host sediment aggregate properties. Physical properties include thermal properties, permeability, electrical conductivity and permittivity, small-strain elastic P and S wave velocities, shear strength, and volume changes resulting from hydrate dissociation. The magnitudes and interdependencies of these properties are critically important for predicting and quantifying macroscale responses of hydrate-bearing sediments to changes in mechanical, thermal, or chemical boundary conditions. These predictions are vital for mitigating borehole, local, and regional slope stability hazards; optimizing recovery techniques for extracting methane from hydrate-bearing sediments or sequestering carbon dioxide in gas hydrate; and evaluating the role of gas hydrate in the global carbon cycle.

AB Background: RNA viruses are responsible for a variety of illnesses among people, including but not limited to the common cold, the flu, HIV, and ebola. Developing new drugs and new strategies for treating diseases caused by these viruses can be an expensive and time-consuming process. Mathematical modeling may be used to elucidate host-pathogen interactions and highlight potential targets for drug development, as well providing the basis for optimizing patient treatment strategies. The purpose of this work was to determine whether a genome-scale modeling approach could be used to understand how metabolism is impacted by the host-pathogen interaction during a viral infection. Escherichia coli/MS2 was used as the host-pathogen model system as MS2 is easy to work with, harmless to humans, but shares many features with eukaryotic viruses. In addition, the genome-scale metabolic model of E. coli is the most comprehensive model at this time.
Results: Employing a metabolic modeling strategy known as "flux balance analysis" coupled with experimental studies, we were able to predict how viral infection would alter bacterial metabolism. Based on our simulations, we predicted that cell growth and biosynthesis of the cell wall would be halted. Furthermore, we predicted a substantial increase in metabolic activity of the pentose phosphate pathway as a means to enhance viral biosynthesis, while a break down in the citric acid cycle was predicted. Also, no changes were predicted in the glycolytic pathway.
Conclusions: Through our approach, we have developed a technique of modeling virus-infected host metabolism and have investigated the metabolic effects of viral infection. These studies may provide insight into how to design better drugs. They also illustrate the potential of extending such metabolic analysis to higher order organisms, including humans.

SO GEOPHYSICAL RESEARCH LETTERS

DT Article
ID DUAL-WAVELENGTH RADAR; MICROWAVE RADIOMETER; STRATUS CLOUD
AB The retrieval of cloud water content using dualfrequency radar attenuation is very sensitive to error in radar reflectivity. Either a long radar dwell time or an average over many range gates is needed to reduce random noise in radar data and thus to obtain accurate retrievals but at the cost of poorer temporal and spatial resolution. In this letter we have shown that, by using advanced mathematical inversion techniques like total variation regularization, vertically resolved liquid water content can be retrieved at an accuracy of about 0.15 gm(-3) at 40 m resolution. This is demonstrated using the co-located Ka-band and W-band cloud radars operated by the Atmospheric Radiation Measurement program. The liquid water path calculated from the radars agrees closely with that from a microwave radiometer, with a mean difference of 70 gm(-2). Comparison with lidar observations reveals that the dual-frequency retrieval also reasonably captures the cloud base height of drizzling clouds-something that is very difficult to determine from radar reflectivity alone.

AB Nitrogen cycle dynamics have the capacity to attenuate the magnitude of global terrestrial carbon sinks and sources driven by CO2 fertilization and changes in climate. In this study, two versions of the terrestrial carbon and nitrogen cycle components of the Integrated Science Assessment Model (ISAM) are used to evaluate how variation in nitrogen availability influences terrestrial carbon sinks and sources in response to changes over the 20th century in global environmental factors including atmospheric CO2 concentration, nitrogen inputs, temperature, precipitation and land use. The two versions of ISAM vary in their treatment of nitrogen availability: ISAM-NC has a terrestrial carbon cycle model coupled to a fully dynamic nitrogen cycle while ISAM-C has an identical carbon cycle model but nitrogen availability is always in sufficient supply. Overall, the two versions of the model estimate approximately the same amount of global mean carbon uptake over the 20th century. However, comparisons of results of ISAM-NC relative to ISAM-C reveal that nitrogen dynamics: (1) reduced the 1990s carbon sink associated with increasing atmospheric CO2 by 0.53 PgC yr(-1) (1 Pg = 10(15) g), (2) reduced the 1990s carbon source associated with changes in temperature and precipitation of 0.34 PgC yr(-1) in the 1990s, (3) an enhanced sink associated with nitrogen inputs by 0.26 PgC yr(-1), and (4) enhanced the 1990s carbon source associated with changes in land use by 0.08 PgC yr(-1) in the 1990s. These effects of nitrogen limitation influenced the spatial distribution of the estimated exchange of CO2 with greater sink activity in high latitudes associated with climate effects and a smaller sink of CO2 in the southeastern United States caused by N limitation associated with both CO2 fertilization and forest regrowth. These results indicate that the dynamics of nitrogen availability are important to consider in assessing the spatial distribution and temporal dynamics of terrestrial carbon sources and sinks.

AB A comprehensive model of terrestrial N dynamics has been developed and coupled with the geographically explicit terrestrial C cycle component of the Integrated Science Assessment Model (ISAM). The coupled C-N cycle model represents all the major processes in the N cycle and all major interactions between C and N that affect plant productivity and soil and litter decomposition. Observations from the LIDET data set were compiled for calibration and evaluation of the decomposition submodel within ISAM. For aboveground decomposition, the calibration is accomplished by optimizing parameters related to four processes: the partitioning of leaf litter between metabolic and structural material, the effect of lignin on decomposition, the climate control on decomposition and N mineralization and immobilization. For belowground decomposition, the calibrated processes include the partitioning of root litter between decomposable and resistant material as a function of litter quality, N mineralization and immobilization. The calibrated model successfully captured both the C and N dynamics during decomposition for all major biomes and a wide range of climate conditions. Model results show that net N immobilization and mineralization during litter decomposition are dominantly controlled by initial N concentration of litter and the mass remaining during decomposition. The highest and lowest soil organic N storage are in tundra (1.24 Kg N m(-2)) and desert soil (0.06 Kg N m(-2)). The vegetation N storage is highest in tropical forests (0.5 Kg N m(-2)), and lowest in tundra and desert (<0.03 Kg N m(-2)). N uptake by vegetation is highest in warm and moist regions, and lowest in cold and dry regions. Higher rates of N leaching are found in tropical regions and subtropical regions where soil moisture is higher. The global patterns of vegetation and soil N, N uptake and N leaching estimated with ISAM are consistent with measurements and previous modeling studies. This gives us confidence that ISAM framework can predict plant N availability and subsequent plant productivity at regional and global scales and furthermore how they can be affected by factors that alter the rate of decomposition, such as increasing atmospheric [CO(2)], climate changes, litter quality, soil microbial activity and/or increased N.

AB Hydride anion (H-) reacts quickly in aqueous solution to form molecular hydrogen (H-2) and hydroxide ion (OH-), but (H-)(H2O) clusters have many PES local minima in which the hydride is solvated by two or more water molecules making dihydrogen bonds. Using ab initio methods applied to (H-)(H2O), clusters for n <= 6 and for n = 20, we explored these clusters' reaction pathways and transition states. At the B3LYP/6-311++G** level of theory, all of the small (2 <= n <= 6) clusters are unstable or barely stable at 0 K: all activation barriers for reaction to form H-2 are under 0.5 kcal/mol, all but one are under 0.2 kcal/mol, and most are negative. In some instances the lowest-barrier reaction pathway is multi-step, requiring H-bond rearrangements first, and those rearrangements are consistent with improving the "presolvation" of the emerging (OH-) in accordance with a "solvation hierarchy." The arrangements explored for n = 20 consist of (H-) encapsulated by a dodecahedral cage with coordination of 3, 4, 5, or 6 at the hydride anion. The lowest-energy (H-)(H2O)(20) cluster found has 4 H-bonds to the anion. Of several reaction pathways explored, the lowest barrier height is 3,68 kcal/mol at 0 K, suggesting that a low-temperature stable solvated hydride can exist. For the (H-)(H2O)(20) Clusters at their transition states to H-2 formation, the H--H distances are at or below the van der Waals cutoff for covalent H-H bonding (92 pm). In all, 21 transition states to (H-2)(OH-)(H2O)(n-1) and eight H-bond rearranging transition states are presented. During a 25 ps AND simulation of H- in a box of 32 H2O's at 300 K, reaction to form H-2 did not occur, the hydride ion spent 95% of the time being 4-coordinated, and two first-shell exchanges were observed. This and other calculations suggest the mean survival time of (H-) in bulk water at 300 K is likely between 20 and 100 ps. (C) 2009 Elsevier B.V. All rights reserved.

ID RAY STANDING WAVES; SURFACE
AB For the case of one-third of a monolayer of tungsten grown by atomic layer deposition on a hematite alpha-Fe2O3(0001) surface, we report direct atomic-scale observations of the structural and chemical changes that occur as this model interfacial system evolves from the as-deposited state to the oxidized state, then to the reduced state, and finally back to the oxidized state. In situ X-ray standing-wave atomic images relative to the hematite lattice show dramatic (but redox-reversible) changes to the W cation locations with respect to the occupied and unoccupied Fe surface sites. These structural changes are concurrent with X-ray photoelectron spectroscopy chemical shift changes, where W is observed to go from the 6+ to 5+ oxidation state. These novel observations of redox-induced cation dynamics in an oxide-supported catalyst are explained by models that account for W incorporation at the interface in Fe sites with various coordination schemes. Our proposed structure models are supported by our X-ray absorption fine structure measurements.

AB Understanding the acid-base behavior of silica surfaces is critical for many nanoscience and bionano interface applications. Silanol groups (SiOH) on silica surfaces exhibit two acidity constants-one as acidic as vinegar-but their structural basis remains controversial. The atomic details of the more acidic silanol site govern not just the overall surface charge density at near neutral solution pH but also how ions and biomolecules interact with and bind to silica immersed in water. Using ab initio molecular dynamics simulations and multiple representative crystalline silica surfaces, we determine the deprotonation free energies of silanol groups with different structural motifs. We show that previously proposed motifs related to chemical connectivity or intersilanol hydrogen bonds do not yield high acidity. Instead, a plausible candiate for pK(a) = 4.5 silanol groups may be found in locally strained or defected regions with sparse silanol coverage. In the process, irreversible ring-opening reactions of strained silica trimer rings in contact with liquid water are observed.

AB Sea urchin teeth are remarkable and complex calcite structures, continuously growing at the forming end and self-sharpening at the mature grinding tip. The calcite (CaCO(3)) crystals of tooth components, plates, fibers, and a high-Mg polycrystalline matrix, have highly co-oriented crystallographic axes. This ability to co-orient calcite in a mineralized structure is shared by all echinoderms. However, the physicochemical mechanism by which calcite crystals become co-oriented in echinoderms remains enigmatic. Here, we show differences in calcite c-axis orientations in the tooth of the purple sea urchin (Strongylocentrotus purpuratus), using high-resolution X-ray photoelectron emission spectromicroscopy (X-PEEM) and microbeam X-ray diffraction (mu XRD). All plates share one crystal orientation, propagated through pillar bridges, while fibers and polycrystalline matrix share another orientation. Furthermore, in the forming end of the tooth, we observe that CaCO(3) is present as amorphous calcium carbonate (ACC). We demonstrate that co-orientation of the nanoparticles in the polycrystalline matrix occurs via solid-state secondary nucleation, propagating out from the previously formed fibers and plates, into the amorphous precursor nanoparticles. Because amorphous precursors were observed in diverse biominerals, solid-state secondary nucleation is likely to be a general mechanism for the co-orientation of biomineral components in organisms from different phyla.

TI Metal- and Hydrogen-Bonding Competition during Water Adsorption on

AB The initial stages of water adsorption on the Pd(111) and Ru(0001) surfaces have been investigated experimentally by scanning tunneling microscopy in the temperature range between 40 and 130 K, and theoretically with density functional theory (DFT) total energy calculations and scanning tunneling microscopy (STM) image simulations. Below 125 K, water dissociation does not occur at any appreciable rate, and only molecular films are formed. Film growth starts by the formation of flat hexamer clusters where the molecules bind to the metal substrate through the O-lone pair while making H-bonds with neighboring molecules. As coverage increases, larger networks of linked hexagons are formed with a honeycomb structure, which requires a fraction of the water molecules to have their molecular plane perpendicular to the metal surface with reduced water-metal interaction. Energy minimization favors the growth of networks with limited width. As additional water molecules adsorb on the surface, they attach to the periphery of existing islands, where they interact only weakly with the metal substrate. These molecules hop along the periphery of the clusters at intermediate temperatures. At higher temperatures, they bind to the metal to continue the honeycomb growth. The water-Ru interaction is significantly stronger than the water-Pd interaction, which is consistent with the greater degree of hydrogen-bonded network formation and reduced water-metal bonding observed on Pd relative to Ru.

AB A number of species of Gram-negative bacteria can use insoluble minerals of Fe(III) and Mn(IV) as extracellular respiratory electron acceptors. In some species of Shewanella, deca-heme electron transfer proteins lie at the extracellular face of the outer membrane (OM), where they can interact with insoluble substrates. To reduce extracellular substrates, these redox proteins must be charged by the inner membrane/periplasmic electron transfer system. Here, we present a spectro-potentiometric characterization of a trans-OM icosa-heme complex, MtrCAB, and demonstrate its capacity to move electrons across a lipid bilayer after incorporation into proteoliposomes. We also show that a stable MtrAB subcomplex can assemble in the absence of MtrC; an MtrBC subcomplex is not assembled in the absence of MtrA; and MtrA is only associated to the membrane in cells when MtrB is present. We propose a model for the modular organization of the MtrCAB complex in which MtrC is an extracellular element that mediates electron transfer to extracellular substrates and MtrB is a trans-OM spanning beta-barrel protein that serves as a sheath, within which MtrA and MtrC exchange electrons. We have identified the MtrAB module in a range of bacterial phyla, suggesting that it is widely used in electron exchange with the extracellular environment.

AB Suppression of nucleation around a gold electrode during pentacene growth on a SiO(2) channel is found by photoemission electron microscopy. Mass flow is driven by the difference between the molecular orientations on SiO(2) and gold. The poor connectivity at the channel/electrode boundary causes degradation in the performance of a field-effect transistor, which is found to be improved by self-assembled monolayer treatment on the electrode (see figure; thickness in monolayers (ML)).

AB We demonstrate an organic photodiode with near infrared optical response out to about 1100 nm with a gain of similar to 10 at 1000 nm under 5 V reverse bias. The diodes employ a soluble naphthalocyanine with a peak absorption coefficient of similar to 10(5) cm(-1) at 1000 nm. In contrast to most organic photodiodes, no exciton dissociating material is used. At zero bias, the diodes are inefficient with an external quantum efficiency of similar to 10(-2). In reverse bias, large gain occurs and is linear with bias voltage above 4 V. The observed gain is consistent with a photoconductive gain mechanism.

AB We report the local measurements of the magnetic penetration depth lambda in a superconducting Nb film using magnetic force microscopy (MFM). We developed a method for quantitative extraction of the penetration depth from single-parameter simultaneous fits to the lateral and height profiles of the MFM signal, and demonstrate that the obtained value is in excellent agreement with that obtained from the bulk magnetization measurements.

AB We have determined the electronic and atomic structure of N doped TiO2 using a combination of hard x-ray photoelectron spectroscopy and first-principles density functional theory calculations. Our results reveal that N doping of TiO2 leads to the formation of oxygen vacancies and the combination of both N impurity and oxygen vacancies accounts for the observed visible light catalytic behavior of N doped TiO2.

AB Ge-based devices, currently being pursued as replacement of their Si counterparts, typically contain a germanium oxide layer next to the substrate. Here we show using first-principles calculations that, in contrast to Si technology, hydrogenation and fluorination are not effective ways of passivating Ge-GeO2 interfacial P-b centers with a Ge dangling bond (DB). Moreover, we identify DB geometries that differ from the P-b structures and we find that the Ge-GeO2 boundary has a higher atomic-scale roughness than the Si-SiO2 interface. These key differences in interface morphology and defect properties are consistent with experimental data.

AB Carrier generation and recombination processes of ZnTeO thin films are studied by time-resolved photoluminescence, where carrier lifetimes at oxygen states and the conduction band are inferred to be >1 mu s and < 100 ps, respectively. The radiative recombination coefficient for optical transitions from oxygen states to the valence band is extracted to be 1.2x10(-10) cm(3) sec(-1) based on the excitation dependence of decay time constants. Rate equation analysis further suggests an increase in electron lifetime at the conduction band as oxygen states occupation is critical in achieving high conversion efficiency for solar cells based on multiphoton processes in these materials.

Different symplectic integrators up to the sixth order have been adapted and optimized in the framework of ab initio self-consistent-field theory. It is shown how the accuracy can be significantly improved compared to a conventional Verlet integration at the same level of computational cost, in particular, for the case of very high accuracy requirements.

AB Coulomb interactions are present in a wide variety of all-atom force fields. Spherical truncations of these interactions permit fast simulations but are problematic due to their incorrect thermodynamics. Herein we demonstrate that simple analytical corrections for the thermodynamics of uniform truncated systems are possible. In particular, results for the simple point charge/extended (SPC/E) water model treated with spherically truncated Coulomb interactions suggested by local molecular field theory [J. M. Rodgers and J. D. Weeks, Proc. Natl. Acad. Sci. U.S.A. 105, 19136 (2008)] are presented. We extend the results developed by Chandler [J. Chem. Phys. 65, 2925 (1976)] so that we may treat the thermodynamics of mixtures of flexible charged and uncharged molecules simulated with spherical truncations. We show that the energy and pressure of spherically truncated bulk SPC/E water are easily corrected using exact second-moment-like conditions on long-ranged structure. Furthermore, applying the pressure correction as an external pressure removes the density errors observed by other research groups in NPT simulations of spherically truncated bulk species.

AB The adaptive kinetic Monte Carlo method was used to calculate the decomposition dynamics of a methanol molecule on Cu(100) at room temperature over a time scale of minutes. Mechanisms of reaction were found using minimum mode following saddle point searches based on forces and energies from density functional theory. Rates of reaction were calculated with harmonic transition state theory. The dynamics followed a pathway from CH3OH, CH3O, CH2O, HCO, and finally to CO. Our calculations confirm that methanol decomposition starts with breaking the O-H bond followed by breaking C-H bonds in the dehydrogenated intermediates until CO is produced. The bridge site on the Cu(100) surface is the active site for scissoring chemical bonds. Reaction intermediates are mobile on the surface which allows them to find this active reaction site. This study illustrates how the adaptive kinetic Monte Carlo method can model the dynamics of surface chemistry from first principles.

AB Here we report a novel twin polarization angle (TPA) approach in the quantitative chirality detection with the surface sum-frequency generation vibrational spectroscopy (SFG-VS). Generally, the achiral contribution dominates the surface SFG-VS signal, and the pure chiral signal is usually two or three orders of magnitude smaller. Therefore, it has been difficult to make quantitative detection and analysis of the chiral contributions to the surface SFG-VS signal. In the TPA method, by varying together the polarization angles of the incoming visible light and the sum frequency signal at fixed s or p polarization of the incoming infrared beam, the polarization dependent SFG signal can give not only direct signature of the chiral contribution in the total SFG-VS signal, but also the accurate measurement of the chiral and achiral components in the surface SFG signal. The general description of the TPA method is presented and the experiment test of the TPA approach is also presented for the SFG-VS from the S- and R-limonene chiral liquid surfaces. The most accurate degree of chiral excess values thus obtained for the 2878 cm(-1) spectral peak of the S- and R-limonene liquid surfaces are (23.7 +/- 0.4)% and (-25.4 +/- 1.3)%, respectively.

AB We have previously reported that organophosphorus hydrolase (OPH) can be spontaneously entrapped in functionalized mesoporous silica (FMS) with HOOC- as the functional groups and the entrapped OPH in HOOC-FMS showed enhanced enzyme specific activity. This work is to study the mechanisms that why OPH entrapped in FMS displayed the enhanced activity in views of OPH-FMS interactions using spectroscopic methods. The circular dichroism (CD) spectra show that, comparing to the secondary structure of OPH free in solution, OPH in HOOC-FMS displayed increased alpha-helix/beta-strand transition of OPH with increased OPH loading density. The fluorescence emission spectra of Trp residues were used to assess the tertiary structural changes of the enzyme. There was a 42% increase in fluorescence. This is in agreement with the fact that the fluorescence intensity of OPH was increased accompanying with the increased OPH activity when decreasing urea concentrations in solution. The steady-state anisotropy was increased after OPH entrapping in HOOC-FMS comparing to the free OPH in solution, indicating that protein mobility was reduced upon entrapment. The solvent accessibility of Trp residues of OPH was probed by using acrylamide as a collisional quencher. Trp residues of OPH-FMS had less solvent exposure comparing with free OPH in solution due to its electrostatical binding to HOOC-FMS thereby displaying the increased fluorescence intensity. These results suggest the interactions of OPH with HOOC-FMS resulted in the protein immobilization and a favorable conformational change for OPH in the crowded confinement space and accordingly the enhanced activity.

AB We report the solubility of carbon dioxide in four physical solvents and compare our data to predicted phase behavior using the conductor-like screening model for real solvents (COSMO-RS) formalism. The solubility data are presented in pressure-composition (Px) diagrams as well as Henry's law coefficients on a wt% basis at 298.15 K. The oligomers presented in this study are poly ethylene glycol di-methyl ether (PEGDME), perfluoro polyether (PFPE), poly di-methyl siloxane (PDMS), and poly propylene glycol di-methyl ether (PPGDME), which is a new solvent designed for this application by our group. These oligomers had 2-5 repeat units. We assess these four oligomers for capturing CO2 from high-pressure streams. The COSMO-RS formalism is able to qualitatively and to some extent quantitatively describe solubilities Of CO2 in each of the oligomers. (C) 2009 Elsevier B.V. All rights reserved.

AB Many bacteria express phosphoenolpyruvate-dependent phosphotransferase systems (PTS). The mannitol-specific PTS catalyze the uptake and phosphorylation of D-mannitol. The uptake system comprises several genes encoded in the single operon. The expression of the mannitol operon is regulated by a proposed transcriptional factor, mannitol operon repressor (MtlR) that was first studied in Escherichia coli. Here we report the first crystal structures of MtlR from Vibrio parahemeolyticus (Vp-MtlR) and its homolog YggD protein from Shigella flexneri (Sf-YggD). MtlR and YggD belong to the same protein family (Pfam05068). Although Vp-MtlR and Sf-YggD share low sequence identity (22%), their overall structures are very similar, representing a novel all alpha-helical fold, and indicate similar function. However, their lack of any known DNA-binding structural motifs and their unfavorable electrostatic properties imply that MtlR/YggD are unlikely to bind a specific DNA operator directly as proposed earlier. This structural observation is further corroborated by in vitro DNA-binding studies of E. coli MtlR (Ec-MtlR), which detected no interaction of Ec-MtlR with the well characterized mannitol operator/promoter region. Therefore, MtlR/YggD belongs to a new class of transcription factors in bacteria that may regulate gene expression indirectly as a part of a larger transcriptional complex.

AB The topic of density-driven convection in porous media has been the focus of many recent studies due to its relevance as a long-term trapping mechanism during geological sequestration of carbon dioxide. Most of these studies have addressed the problem in homogeneous and anisotropic permeability fields using linear-stability analysis, and relatively little attention has been paid to the analysis for heterogeneous systems. Previous investigators have reduced the governing equations to an initial-value problem and have analysed it either with a quasi-steady-state approximation model or using numerical integration with arbitrary initial perturbations. Recently, Rapaka et al. (J. Fluid Mech., vol. 609, 2008, pp. 285-303) used the idea of non-modal stability analysis to compute the maximum amplification of perturbations in this system, optimized over the entire space of initial perturbations. This technique is a mathematically rigorous extension of the traditional normal-mode analysis to non-normal and time-dependent problems. In this work, we extend this analysis to the important cases of anisotropic and layered porous media with a permeability variation in the vertical direction. The governing equations are linearized and reduced to a set of coupled ordinary differential equations of the initial-value type using the Galerkin technique. Non-modal stability analysis is used to compute the maximum growth of perturbations along with the optimal wavenumber leading to this growth. We show that unlike the solution of the initial-value problem, results obtained using non-modal analysis are insensitive to the choice of bottom boundary condition. For the anisotropic problem, the dependence of critical time and wavenumber on the anisotropy ratio was found to be in good agreement with theoretical scalings proposed by Ennis-King et al. (Phys. Fluids, vol. 17, 2005, paper no. 084107). For heterogeneous systems, we show that uncertainty in the permeability field at low wavenumbers can influence the growth of perturbations. We use a Monte Carlo approach to compute the mean and standard deviation of the critical time for a sample permeability field. The results from theory are also compared with finite-volume simulations of the governing equations using fully heterogeneous porous media with strong layering. We show that the results from non-modal stability analysis match extremely well with those obtained from the simulations as long as the assumption of strong layering remains valid.

AB A pack cementation process was developed to coat commercial 9% Cr ferritic-martensitic steel T91 at temperatures below its normal tempering temperature to avoid any potential detrimental effect on the mechanical properties of the coated alloy. In order to prevent the formation of Fe(2)Al(5) coatings, the Al activity in the pack cementation process was reduced by substituting the pure Al masteralloy with binary Cr-Al masterailloys containing either 15 or 25 wt.% Al. When the Cr-25Al masteralloy was used, a duplex coating was formed at 700 degrees C, consisting of a thin Fe(2)Al(5) outer layer and an inner layer of FeAl. With the Cr-15Al masteralloy, an FeAl coating of similar to 12 mu m thick was achieved at 700 degrees C. The pack aluminicle coatings fabricated at 700 degrees C are being evaluated in air + 10 vol.% H(2)O at 650 degrees C and 700 degrees C to determine their long-term oxidation performance.

AB Research on the behavior of high-purity, low-density (85%) air plasma sprayed (APS) thermal barrier coatings (TBC) with NiCoCrAlY bond coats deposited by argon-shrouded plasma spraying is described. The microstructure of the APS topcoats is one variable in this study intended to maximize the coating thicknesses that can be applied without spallation and to minimize the thermal conduction through the YSZ layer. The specimens were evaluated using cyclic oxidation tests and important properties of the TBCs, such as resistance to sintering and phase transformation, were determined.
The high purity resulted in top coats which are highly resistant to sintering and transformation from the metastable tetragonal phase to the equilibrium mixture of monoclinic and cubic phases. The porous topcoat microstructure also resulted in significant durability during thermal cycling. The actual failure mechanisms of the APS coatings were found to depend on topcoat thickness, CTE of the superalloy substrate and the nature of the thermal exposure. (C) 2009 Elsevier B.V.

AB This study compared the oxidation behaviors of gamma-gamma ' NiPtAl coatings and traditional beta-phase NiPtAl bond coatings. Both types of NiPtAl coatings were fabricated on two different single-crystal Ni-base superalloys using the same source of electroplated Pt. Characterization of the coating composition and alumina scale morphology after cyclic oxidation in dry oxygen at 1150 degrees C indicated that the addition of Ti in one superalloy had affected the scale microstructure and had degraded scale adhesion on the gamma-gamma' coating. In general, the alumina scale formed was thicker on the gamma-gamma'-coated substrates, and those coatings contained a larger number of pores, thought likely to be primarily due to a Kirkendall-type effect.

AB Suzaku X-ray observations of a young supernova remnant, Cassiopeia A, were carried out. K-shell transition lines from highly ionized ions of various elements were detected, including Chromium (Cr-K alpha at 5.61 keV). The X-ray continuum spectra were modeled in the 3.4-40keV band, summed over the entire remnant, and were fitted with a simplest combination of the thermal bremsstrahlung and the non-thermal cut-off power-law models. The spectral fits with this assumption indicate that the continuum emission is likely to be dominated by non-thermal emission with a cut-off energy at > 1 keV. The thermal-to-non thermal fraction of the continuum flux in the 4-10 keV band is best estimated as similar to 0.1. Non-thermal-dominated continuum images in the 4-14 keV band were made. The peak of the non-thermal X-rays appears at the western part. The peak position of the TeV gamma-rays measured with HEGRA and MAGIC is also shifted at the western part with the I-sigma confidence. Since the location of the X-ray continuum emission was known to be presumably identified with the reverse shock region, the possible keV-TeV correlations give a hint that the accelerated multi-TeV hadrons in Cassiopeia A are dominated by heavy elements in the reverse shock region.

AB We conducted a study to estimate the maximum tolerated dose (MTD) of I-131-anti-CD45 antibody (Ab; BC8) that can be combined with a standard reduced-intensity conditioning regimen before allogeneic hematopoietic cell transplantation. Fifty-eight patients older than 50 years with advanced acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS) were treated with I-131-BC8 Ab and fludarabine plus 2 Gy total body irradiation. Eighty-six percent of patients had AML or MDS with greater than 5% marrow blasts at the time of transplantation. Treatment produced a complete remission in all patients, and all had 100% donor-derived CD3(+) and CD33(+) cells in the blood by day 28 after the transplantation. The MTD of I-131-BC8 Ab delivered to liver was estimated to be 24 Gy. Seven patients (12%) died of nonrelapse causes by day 100. The estimated probability of recurrent malignancy at 1 year is 40%, and the 1-year survival estimate is 41%. These results show that CD45-targeted radiotherapy can be safely combined with a reduced-intensity conditioning regimen to yield encouraging overall survival for older, high-risk patients with AML or MDS. This study was registered at www.clinicaltrials.govas # NCT00008177. (Blood. 2009; 114: 5444-5453)

AB The near-unity efficiency of energy transfer in photosynthesis makes photosynthetic light-harvesting complexes a promising avenue for developing new renewable energy technologies. Knowledge of the energy landscape of these complexes is essential in understanding their function, but its experimental determination has proven elusive. Here, the observation of quantum coherence using two-dimensional electronic spectroscopy is employed to directly measure the 14 lowest electronic energy levels in light-harvesting complex II (LHCII), the most abundant antenna complex in plants containing approximately 50% of the world's chlorophyll, We observe that the electronically excited states are relatively evenly distributed, highlighting an important design principle of photosynthetic complexes that explains the observed ultrafast intracomplex energy transfer in LHCII.

AB The structure of spinach light-harvesting complex II (LHC II), stabilized in a solution of the detergent n-octyl-beta-D-glucoside (BOG), was investigated by small-angle neutron scattering (SANS). Physicochemical characterization of the isolated complex indicated that it was pure (>95%) and also in its native trimeric state. SANS with contrast variation was used to investigate the properties of the protein-detergent complex at three different H(2)O/D(2)O contrast match points, enabling the scattering properties of the protein and detergent to be investigated independently. The topological shape of LHC 11, determined using ab initio shape restoration methods from the SANS data at the contrast match point of BOG, was consistent with the X-ray crystallographic structure of LHC 11 (Liu et al. Nature 2004 428, 287-292). The interactions of the protein and detergent were investigated at the contrast match point for the protein and also in 100% D(2)O. The data suggested that BOG micelle structure was altered by its interaction with LHC 11, but large aggregate structures were not Formed. Indirect Fourier transform analysis of the LHC II/BOG scattering curves showed that the increase in the maximum dimension of the protein-detergent complex was consistent with the presence of a monolayer of detergent Surrounding the protein. A model of the LHC II/BOG complex was generated to interpret the measurements made in 100% D(2)O. This model adequately reproduced the overall size of the LHC II/BOG complex, but demonstrated that the detergent does not have a highly regular shape that surrounds the hydrophobic periphery of LHC II. In addition to demonstrating that natively Structured LHC 11 can be produced for functional characterization and for use in artificial solar energy applications, the analysis and modeling approaches described here can be used for characterizing detergent-associated alpha-helical transmembrane proteins.

ID MICROBIAL DIVERSITY; PROTEIN FAMILIES; DATABASE GOLD; PROJECTS; SEQUENCE
AB Sequencing of bacterial and archaeal genomes has revolutionized our understanding of the many roles played by microorganisms(1). There are now nearly 1,000 completed bacterial and archaeal genomes available(2), most of which were chosen for sequencing on the basis of their physiology. As a result, the perspective provided by the currently available genomes is limited by a highly biased phylogenetic distribution(3-5). To explore the value added by choosing microbial genomes for sequencing on the basis of their evolutionary relationships, we have sequenced and analysed the genomes of 56 culturable species of Bacteria and Archaea selected to maximize phylogenetic coverage. Analysis of these genomes demonstrated pronounced benefits ( compared to an equivalent set of genomes randomly selected from the existing database) in diverse areas including the reconstruction of phylogenetic history, the discovery of new protein families and biological properties, and the prediction of functions for known genes from other organisms. Our results strongly support the need for systematic 'phylogenomic' efforts to compile a phylogeny-driven 'Genomic Encyclopedia of Bacteria and Archaea' in order to derive maximum knowledge from existing microbial genome data as well as from genome sequences to come.

AB Protein design provides a rigorous test of our knowledge about proteins and allows the creation of novel enzymes for biotechnological applications. Whereas progress has been made in designing proteins that mimic native proteins structurally(1-3), it is more difficult to design functional proteins(4-8). In comparison to recent successes in designing non-metalloproteins(4,6,7,9,10), it is even more challenging to rationally design metalloproteins that reproduce both the structure and function of native metalloenzymes(5,8,11-20). This is because protein metal-binding sites are much more varied than non-metal-containing sites, in terms of different metal ion oxidation states, preferred geometry and metal ion ligand donor sets. Because of their variability, it has been difficult to predict metal-binding site properties in silico, as many of the parameters, such as force fields, are ill-defined. Therefore, the successful design of a structural and functional metalloprotein would greatly advance the field of protein design and our understanding of enzymes. Here we report a successful, rational design of a structural and functional model of a metalloprotein, nitric oxide reductase (NOR), by introducing three histidines and one glutamate, predicted as ligands in the active site of NOR, into the distal pocket of myoglobin. A crystal structure of the designed protein confirms that the minimized computer model contains a haem/non-haem Fe(B) centre that is remarkably similar to that in the crystal structure. This designed protein also exhibits NO reduction activity, and so models both the structure and function of NOR, offering insight that the active site glutamate is required for both iron binding and activity. These results show that structural and functional metalloproteins can be rationally designed in silico.

AB Genome sequences are annotated by computational prediction of coding sequences, followed by similarity searches such as BLAST, which provide a layer of possible functional information. While the existence of processes such as alternative splicing complicates matters for eukaryote genomes, the view of bacterial genomes as a linear series of closely spaced genes leads to the assumption that computational annotations that predict such arrangements completely describe the coding capacity of bacterial genomes. We undertook a proteomic study to identify proteins expressed by Pseudomonas fluorescens Pf0-1 from genes that were not predicted during the genome annotation. Mapping peptides to the Pf0-1 genome sequence identified sixteen non-annotated protein-coding regions, of which nine were antisense to predicted genes, six were intergenic, and one read in the same direction as an annotated gene but in a different frame. The expression of all but one of the newly discovered genes was verified by RT-PCR. Few clues as to the function of the new genes were gleaned from informatic analyses, but potential orthologs in other Pseudomonas genomes were identified for eight of the new genes. The 16 newly identified genes improve the quality of the Pf0-1 genome annotation, and the detection of antisense protein-coding genes indicates the under-appreciated complexity of bacterial genome organization.

AB Five CHB(11)X(6)Y(5)(-) carborane anions from the series X = Br, Cl, I and Y = H, Cl, CH(3) were generated by electrospray ionization, and their reactivity with a series of Bronsted acids and electron transfer reagents were examined in the gas phase. The undecachlorocarborane acid, H(CHB(11)Cl(11)), was found to be far more acidic than the former record holder, (1-C(4)F(9)SO(2))(2)NH (i.e., Delta H degrees(acid) = 241 +/- 29 vs 291.1 +/- 2.2 kcal mol(-1)) and bridges the gas-phase acidity and basicity scales for the first time. Its conjugate base, CHB(11)Cl(11)(-), was found by photoelectron spectroscopy to have a remarkably large electron binding energy (6.35 +/- 0.02 eV) but the value for the (1-C(4)F(9)SO(2))(2)N(-) anion is even larger (6.5 +/- 0.1 eV). Consequently, it is the weak H-(CHB(11)Cl(11)) BDE (70.0 kcal mol(-1), G3(MP2)) compared to the strong BDE of (1-C(4)F(9)SO(2))(2)N-H (127.4 +/- 3.2 kcal mol(-1)) that accounts for the greater acidity of carborane acids.

AB Neutron reflectometry was used to examine the interactions of polymer electrolyte fuel cell (PEFC) materials that comprise the triple-phase interface. Smooth, idealized layers of Nafion on glassy carbon (GC) and Pt surfaces were used to experimentally model the PEFC electrode interfaces. Different multilayer structures of Nafion were found in contact with the Pt or GC surfaces. These structures showed separate hydrophobic and hydrophilic domains formed within the Nafion layer when equilibrated with saturated D(2)O vapor. A hydrophobic Nafion region was formed adjacent to a Pt film. However, when Nafion was in contact with a PtO surface, the Nafion at the Pt interface became hydrophilic. The adsorbed oxide layer caused a long-range restructuring of the perfluorosulfonic acid polymer chains that comprise Nafion. The thicknesses of the hydrophobic and hydrophilic domains changed to the same magnitude when the oxide layer was present compared to a thin hydrophobic domain in contact with Pt. A three-layer Nafion structure was formed when Nafion was in direct contact with GC. The findings in this research are direct experimental evidence that both the interfacial and long-range structural properties of Nafion are affected by the material with which it is in contact. Evidence of physical changes of aged Nafion films was obtained, and the results showed a permanent increase in the thickness of the Nafion film and a decrease in the scattering length density (SLID), which are attributed to irreversible swelling of the Nafion film. The aging also resulted in a decrease in the SLID of the GC substrate, which is likely due to either an increase in surface oxidation of the carbon or loss of carbon mass at the GC surface.

AB The folding of a 15-residue beta-hairpin peptide (Peptide 1) is characterized using multiple unbiased, atomistic molecular dynamics (MD) simulations. Fifteen independent MD trajectories, each 2.5 mu s-long for a total of 37.5 mu s, are performed of the peptide in explicit solvent, at room temperature, and without the use of enhanced sampling techniques. The computed folding time of 1-1.5 mu s obtained from the simulations is in good agreement with experiment [Xu, Y.; et al. J. Am. Chem. Soc. 2003, 125, 15388-15394]. A common folding mechanism is observed, in which the turn is always found to be the major determinant in initiating the folding process, followed by cooperative formation of the interstrand hydrogen bonds and the side-chain packing. Furthermore, direct transition to the folded state from fully unstructured conformations does not take place. Instead, the peptide is always observed to form partially structured conformations involving a non-native (ESYI) turn from which the native (NPDG) turn forms, triggering the folding to the beta-hairpin.

AB Predicting whether a molecule can traverse chemical labyrinths of channels, tunnels, and buried cavities usually requires performing computationally intensive molecular dynamics simulations. Often one wants to screen molecules to identify ones that can pass through a given chemical labyrinth or screen chemical labyrinths to identify those that allow a given molecule to pass. Because it is impractical to test each molecule/ labyrinth pair using computationally expensive methods, faster, approximate methods are used to prune possibilities, "triaging" the ability of a proposed molecule to pass through the given chemical labyrinth. Most pruning methods estimate chemical accessibility solely on geometry, treating atoms or groups of atoms as hard spheres with appropriate radii. Here, we explore geometric configurations for a moving "molecular worm," which replaces spherical probes and is assembled from solid blocks connected by flexible links. The key is to extend the fast marching method, which is an ordered upwind one-pass Dijkstra-like method to compute optimal paths by efficiently solving an associated Eikonal equation for the cost function. First, we build a suitable cost function associated with each possible configuration, and second, we construct an algorithm that works in ensuing high-dimensional configuration space: at least seven dimensions are required to account for translational, rotational, and internal degrees of freedom. We demonstrate the algorithm to study shortest paths, compute accessible volume, and derive information on topology of the accessible part of a chemical labyrinth. As a model example, we consider an alkane molecule in a porous material, which is relevant to designing catalysts for oil processing.

AB With the realization that many calcified skeletons form by processes involving a precursor phase of amorphous calcium carbonate (ACC), a new paradigm for mineralization is emerging. There is evidence the Mg content in biogenic ACC is regulated by carboxylated (acidic) proteins and other macromolecules, but the physical basis for such a process is unknown. We test the hypothesis that ACC compositions express a systematic relationship to the chemistry of carboxyl-rich biomolecules. A series of inorganic control experiments were conducted to establish the dependence of Mg/Ca ratios in ACC on solution composition. We then determined the influence of a suite of simple carboxylated organic acids on Mg content. Molecules with a strong affinity for binding Ca compared with Mg promote the formation of Mg-enriched ACC that is compositionally equivalent to high-magnesium calcites and dolomite. Measurements show Mg/Ca ratios are controlled by a predictable dependence upon the binding properties of the organic molecules. The trend appears rooted in the conformation and electrostatic potential topology of each molecule, but dynamic factors also may be involved. The dependence suggests a physical basis for reports that specific sequences of calcifying proteins are critical to modulating mineralization. Insights from this study may provide a plausible explanation for why some biogenic carbonates and carbonaceous cements often contain higher Mg signatures than those that are possible by classical crystal growth processes. The findings reiterate the controls of microenvironment on mineralization and suggest an origin of compositional offsets, or vital effects, long recognized by the paleoclimate community.

AB Nitric oxide (NO) regulates a number of essential physiological processes by activating soluble guanylate cyclase (sGC) to produce the second messenger cGMP. The mechanism of NO sensing was previously thought to result exclusively from NO binding to the sGC heme; however, recent studies indicate that heme-bound NO only partially activates sGC and additional NO is involved in the mechanism of maximal NO activation. Furthermore, thiol oxidation of sGC cysteines results in the loss of enzyme activity. Herein the role of cysteines in NO-stimulated sGC activity investigated. We find that the thiol modifying reagent methyl methanethiosulfonate specifically inhibits NO activation of sGC by blocking a non-heme site, which defines a role for sGC cysteine(s) in mediating NO binding. The nature of the NO/cysteine interaction was probed by examining the effects of redox active reagents on NO-stimulated activity. These results show that NO binding to, and dissociation from, the critical cysteine(s) does not involve a change in the thiol redox state. Evidence is provided for non-heme NO in the physiological activation of sGC in context of a primary cell culture of human umbilical vein endothelial cells. These findings have relevance to diseases involving the NO/cGMP signaling pathway.

AB The kinase domain of human epidermal growth factor receptor (HER) 3/ErbB3, a member of the EGF receptor (EGFR) family, lacks several residues that are critical for catalysis. Because catalytic activity in EGFR family members is switched on by an allosteric interaction between kinase domains in an asymmetric kinase domain dimer, HER3 might be specialized to serve as an activator of other EGFR family members. We have determined the crystal structure of the HER3 kinase domain and show that it appears to be locked into an inactive conformation that resembles that of EGFR and HER4. Although the crystal structure shows that the HER3 kinase domain binds ATP, we confirm that it is catalytically inactive but can serve as an activator of the EGFR kinase domain. The HER3 kinase domain forms a dimer in the crystal, mediated by hydrophobic contacts between the N-terminal lobes of the kinase domains. This N-lobe dimer closely resembles a dimer formed by inactive HER4 kinase domains in crystal structures determined previously, and molecular dynamics simulations suggest that the HER3 and HER4 N-lobe dimers are stable. The kinase domains of HER3 and HER4 form similar chains in their respective crystal lattices, in which N-lobe dimers are linked together by reciprocal exchange of C-terminal tails. The conservation of this tiling pattern in HER3 and HER4, which is the closest evolutionary homolog of HER3, might represent a general mechanism by which this branch of the HER receptors restricts ligand-independent formation of active heterodimers with other members of the EGFR family.

RESONANCE
AB The traditional site-directed spin labeling (SDSL) method, which utilizes cysteine residues and sulfhydryl-reactive nitroxide reagents, can be challenging for proteins that contain functionally important native cysteine residues or disulfide bonds. To make SDSL amenable to any protein, we introduce an orthogonal labeling strategy, i.e., one that does not rely on any of the functional groups found in the common 20 amino acids. In this method, the genetically encoded unnatural amino acid p-acetyl-L-phenylalanine (p-AcPhe) is reacted with a hydroxylamine reagent to generate a nitroxide side chain (K1). The utility of this scheme was demonstrated with seven mutants of T4 lysozyme, each containing a single p-AcPhe at a solvent-exposed helix site; the mutants were expressed in amounts qualitatively similar to the wild-type protein. In general, the EPR spectra of the resulting K1 mutants reflect higher nitroxide mobilities than the spectra of analogous mutants containing the more constrained disulfide-linked side chain (R1) commonly used in SDSL. Despite this increased flexibility, site dependence of the EPR spectra suggests that K1 will be a useful sensor of local structure and of conformational changes in solution. Distance measurements between pairs of K1 residues using double electron electron resonance (DEER) spectroscopy indicate that K1 will also be useful for distance mapping.

AB Iron deprivation activates the expression of components of the siderophore-mediated iron acquisition systems in Bacillus subtilis, including not only the synthesis and uptake of its siderophore bacillibactin but also expression of multiple ABC transporters for iron scavenging using xenosiderophores. The yclNOPQ operon is shown to encode the complete transporter for petrobactin (PB), a photoreactive 3,4-catecholate siderophore produced by many members of the B. cereus group, including B. anthracis. Isogenic disruption mutants in the yclNOPQ transporter, including permease YclN, ATPase YclP, and a substrate-binding protein YclQ, are unable to use either PB or the photoproduct of FePB (FePB(nu)) for iron delivery and growth, in contrast to the wild-type B. subtilis. Complementation of the mutations with the copies of the respective genes restores this capability. The YclQ receptor binds selectively iron-free and ferric PB, the PB precursor, 3,4-dihydroxybenzoic acid (3,4-DHB), and FePB(nu) with high affinity; the ferric complexes are seen in ESI-MS, implying strong electrostatic interaction between the protein-binding pocket and siderophore. The first structure of a Gram-positive siderophore receptor is presented. The 1.75-angstrom crystal structure of YclQ reveals a bilobal periplasmic binding protein (PBP) fold consisting of two alpha/beta/gamma sandwich domains connected by a long alpha-helix with the binding pocket containing conserved positively charged and aromatic residues and large enough to accommodate FePB. Orthologs of the B. subtilis PB-transporter YclNOPQ in PB-producing Bacilli are likely contributors to the pathogenicity of these species and provide a potential target for antibacterial strategies.

AB We demonstrate the use of laser processing to affect the nucleation of crystallites in thermally annealed hydrogenated amorphous silicon (a-Si:H) thin films. The influence of film H content and subcrystallization threshold laser fluence are investigated by x-ray diffraction measurements during in situ thermal annealing at 600 degrees C. All laser-treated films show a reduced incubation time for crystallization compared to as-grown films, with the largest differences exhibited for samples with higher film H and higher laser fluences. These results are consistent with multivacancy annihilation by laser processing, based upon a recently developed model for a nucleation center in a-Si: H. (C) 2009 American Institute of Physics.

AB To explore the capture dynamics of photoexcited carriers in semiconductor quantum posts, optical pump terahertz (THz) probe and time-resolved photoluminescence spectroscopy were performed. The results of the THz experiment show that after ultrafast excitation, electrons relax within a few picoseconds into the quantum posts, which act as efficient traps. The saturation of the quantum post states, probed by photoluminescence, was reached at approximately ten times the quantum post density in the samples. The results imply that quantum posts are highly attractive nanostructures for future device applications. (C) 2009 American Institute of Physics. [doi:10.1063/1.3275666]

AB We report a joint experimental and theoretical investigation of exciton diffusion in phenyl-cored thiophene dendrimers. Experimental exciton diffusion lengths of the dendrimers vary between 8 and 17 nm, increasing with the size of the dendrimer. A theoretical methodology is developed to estimate exciton diffusion lengths for conjugated small molecules in a simulated amorphous film. The theoretical approach exploits Fermi's Golden Rule to estimate the energy transfer rates for a large ensemble of bimolecular complexes in random relative orientations. Utilization of Poisson's equation in the evaluation of the Coulomb integral leads to very efficient calculation of excitonic couplings between the donor and the acceptor chromophores. Electronic coupling calculations with delocalized transition densities revealed efficient coupling pathways in the bulk of the material, but do not result in strong couplings between the chromophores which are calculated for more localized transition densities. The molecular structures of dendrimers seem to be playing a significant role in the magnitude of electronic coupling between chromophores. Simulated diffusion lengths correlate well with the experimental data. The chemical structure of the chromophore, the shape of the transition densities and the exciton lifetime are found to be the most important factors in determining the size of the exciton diffusion length in amorphous films of conjugated materials.

AB Structural characterization of a mononuclear uranyl complex with a tetradentate, thiophene-linked bis(3-hydroxy-N-methylpyridin-2-one) ligand reveals the most planar coordination geometry yet observed with this ligand class. The introduction of ethylsulfanyl groups onto the thiophene linker disrupts this planar, conjugated ligand arrangement, resulting in the formation of dimeric (UO(2))(2)L(2) species in which each ligand spans two uranyl centers. Relative energy calculations reveal that this tendency toward dimer formation is the result of steric interference between ethylsulfanyl substitutents and linking amides.

The structure comprises MS4 (M = Cu or Ag) tetrahedra and NpS6 octahedra that edge share to form (2)(infinity)[MNpS3-] layers. These layers are separated by the alkali-metal cations. The Np-S bond lengths vary from 2.681(2) to 2.754(1) angstrom. When compared to the corresponding isostructural Th and U compounds these bond distances obey the expected actinide contraction. As the structure contains no S-S bonds, formal oxidation states of +1/+1/+4/-2 may 4 be assigned to A/M/Np/S, respectively. From these results a value of 2.57 for the bond-valence parameter r(0) for Np4+-S2- has been derived and applied to the estimation of the formal oxidation states of Np in the binary NpxSy compounds whose structures are known.

The addition of I(2) and AgX to 1 leads to the formation of uranium(VI) dihalide complexes with the general formula U(N(t)Bu)(2)(I)(X)((t)Bu(2)bpy) (X = I (3), Cl (4), Br (5)). Complexes 1 and 2 can also reduce PhEEPh to generate uranium(VI) complexes with the general formula U(N(t)Bu)(2)(X)(EPh)((t)Bu(2)bpy) (X = I, E = S (6), Se (8), Te (10); X = SPh, E = S (7), Se (12)). These unsymmetrical complexes appear to be in equilibrium with the uranium(VI) complexes U(N(t)Bu)(2)(X)(2)((t)Bu(2)bpy) and U((t)'Bu)(2)(EPh)(2)((t)Bu(2)bpy) (E = Se (9), Te (11)) and suggest that both U-I and U-E bonds possess a labile nature in bis(imido) uranium(VI) complexes. Complex 1 also reacts as a two-electron reductant toward chalcogen atom transfer reagents such as 4-methylmorpholine N-oxide, S(8), and Se to produce dimeric bis(imido) uranium(VI) complexes with the general formula [U(N(t)Bu)(2)(I)((t)Bu(2)bpy)](2)(mu-E) (E = O (13), S (14), Se (15)) and [U(N(t)Bu)(2)(I)((t)Bu(2)bpy)](2)(mu-eta(2):eta(2-)E(4)) (E = S (16), Se (17)). Density functional theory studies performed on a model complex of 13 indicate the presence of multiple bonding in the bridging U-O bond.

AB Portable NMR systems generally suffer from poor field homogeneity and are therefore used more commonly for imaging and relaxation measurements rather than for spectroscopy. In recent years, various approaches have been proposed to increase the sample volume that is usable for spectroscopy. These include approaches based on manual shimming and those based on clever combinations of modulated radio frequency and gradient fields. However, this volume remains small and, therefore, of limited utility. We present improved pulses designed to correct for inhomogeneous dispersion across wide ranges of frequency offsets without eliminating chemical shift or spatial encoding. This method, based on the adiabatic double passage, combines the relatively larger corrections available from spatially matched rf gradients [C. Meriles , J. Magn. Reson. 164, 177 (2003)]. with the adjustable corrections available from time-modulated static field gradients [D. Topgaard , Proc. Natl. Acad. Sci. U.S.A. 101, 17576 (2004)]. We explain the origins of these corrections with a theoretical model that simplifies and expedites the design of the pulse waveforms. We also present a generalized method for evaluating and comparing pulses designed for inhomogeneity correction. Experiments validate this method and support simulations that offer new possibilities for significantly enhanced performance in portable environments.

AB The radial distribution function (RDF) of liquid water has been determined by x-ray scattering. Using a free-standing water jet and a diffracted beam analyzer to separate the Compton from the elastic scattering experimentally, several significant sources of error have been eliminated in the experiment. These have enabled the collection of quality data out to 19.7 A degrees(-1). Data were collected both at 278 K and at 296 K. Our RDF presents fine structure, particularly, a distinct peak at 3.4 A degrees and a peak split at 4.5 A degrees. These features cannot be interpreted by a simple tetrahedral configuration suggested by continuum models. The uncertainties due to the truncation effects and the choice of scattering factors are found to have little influence on the RDF at intermolecular distances.

AB We report a joint experimental and theoretical study of CO chemisorption on the golden cages. We find that the Au(17)- cage is highly robust and retains its cage structure in Au(17)(CO)(-). On the other hand, the Au(16)- cage is transformed to a structure similar to Au(17)- upon the adsorption of CO. Au(18)- is known to consist of two nearly degenerate structures, i.e., a cage and a pyramidal isomer, which coexist in the cluster beam. However, upon CO chemisorption only the cage isomer is observed while the pyramidal isomer no longer exists due to its less favorable interaction with CO, compared to the cage isomer. We find that inclusion of the spin-orbit effects is critical in yielding simulated spectra in quantitative agreement with the experimental data and providing unequivocal structural information and molecular insights into the chemical interactions between CO and the golden cages.

AB The recently introduced energy expansion based on the use of generating functional (GF) [K. Kowalski and P. D. Fan, J. Chem. Phys. 130, 084112 (2009)] provides a way of constructing size-consistent noniterative coupled cluster (CC) corrections in terms of moments of the CC equations. To take advantage of this expansion in a strongly interacting regime, the regularization of the cluster amplitudes is required in order to counteract the effect of excessive growth of the norm of the CC wave function. Although proven to be efficient, the previously discussed form of the regularization does not lead to rigorously size-consistent corrections. In this paper we address the issue of size-consistent regularization of the GF expansion by redefining the equations for the cluster amplitudes. The performance and basic features of proposed methodology are illustrated on several gas-phase benchmark systems. Moreover, the regularized GF approaches are combined with quantum mechanical molecular mechanics module and applied to describe the S(N)2 reaction of CHCl3 and OH- in aqueous solution.

AB In order to produce specific complex structures from a large set of similar biochemical building blocks, many biochemical systems require high sensitivity to small molecular differences. The first and most common model used to explain this high specificity is kinetic proofreading, which has been extended to a variety of systems from detection of DNA mismatch to cell signaling processes. While the specification properties of kinetic proofreading models are well known and were studied in various contexts, very little is known about their temporal behavior. In this work, we study the dynamical properties of discrete stochastic two-branch kinetic proofreading schemes. Using the Laplace transform of the corresponding chemical master equation, we obtain an analytical solution for the completion time distribution. In particular we provide expressions for the specificity as well as the mean and variance of the process completion times. We also show that, for a wide range of parameters, a process distinguishing between two different products can be reduced to a much simpler three-point process. Our results allow for the systematic study of the interplay between specificity and completion times, as well as testing the validity of the kinetic proofreading model in biological systems.

AB We present the first femtosecond soft x-ray spectroscopy in liquids, enabling the observation of changes in hydrogen bond structures in water via core-hole excitation. The oxygen K-edge of vibrationally excited water is probed with femtosecond soft x-ray pulses, exploiting the relation between different water structures and distinct x-ray spectral features. After excitation of the intramolecular OH stretching vibration, characteristic x-ray absorption changes monitor the conversion of strongly hydrogen-bonded water structures to more disordered structures with weaker hydrogen-bonding described by a single subpicosecond time constant. The latter describes the thermalization time of vibrational excitations and defines the characteristic maximum rate with which nonequilibrium populations of more strongly hydrogen-bonded water structures convert to less-bonded ones. On short time scales, the relaxation of vibrational excitations leads to a transient high-pressure state and a transient absorption spectrum different from that of statically heated water.

AB The electron-hole (e-h) exchange interaction leads to the splitting of the exciton into a pair of bright and a pair of dark states. This bright-dark-or singlet-triplet-exciton splitting was historically calculated as the sum of a longrange (LR) and a short-range (SR) component. Using a numerical atomistic approach, we are able to calculate the exchange integrals as a function of the e-h range of interaction S, revealing the 'internal' structure of the integrals. We apply this procedure to thickness-fluctuation GaAs/AlGaAs quantum dots (QDs), self-assembled InAs/GaAs QDs and colloidal InAs QDs. We find a heterogeneous situation, where the SR component contributes similar to 10, similar to 20-30 and similar to 20-50% to the total e-h exchange splitting, which is in the range of 10, 100 and 10 000 mu eV, for the three types of QDs, respectively. The balance between SR and LR is found to depend critically on the size, shape and type of structure. For all types of QDs we find, surprisingly, a range of interaction, close to the physical dimension of the structures, contributing to a reduction of the integral's magnitude. These results highlight the complexity of the exchange interaction, warning against simplified models, and establish the basic features of the nature and origin of dark-bright excitonic splitting in QDs.

AB Experimental studies of light emission phenomena in superconducting RF cavities, which we categorize under the general heading of cavity lights, are described. The cavity lights data, which were obtained using a small CCD video camera, were collected in a series of nine experimental runs ranging from similar to 1/2 to similar to 2 h in duration. The video data were recorded on a standard VHS tape. As the runs progressed, additional instrumentation was added. For the last three runs a LabVIEW-controlled data acquisition system was included. These runs furnish evidence for several, possibly related, light emission phenomena. The most intriguing of these is what appear to be small luminous objects <= 1.5 mm in size, freely moving about in the vacuum space, generally without wall contact, as verified by reflections of the tracks in the cavity walls. In addition, on a number of occasions, these objects were observed to bounce off of the cavity walls. The wall-bounce aspect of most of these events was clearly confirmed by pre-bounce and post-bounce reflections concurrent with the tracks. In one of the later runs a mode of, behavior was observed that was qualitatively different from anything observed in the earlier runs. Perhaps the most perplexing aspect of this new mode was the observation of as many as seven luminous objects arrayed in what might be described as a macromolecular formation, coherently moving about in the interior of the cavity for extended periods of time, evidently without any wall contact. It is suggested that these mobile luminous objects are without explanation within the realm of established physics. Some remarks about more exotic theoretical possibilities are made, and future plans are discussed. (C) 2009 Elsevier B.V. All rights reserved.

AB An algorithm, based on the chi(2) test, employed for particle identification by RICH detectors, is described. This algorithm is independent and complementary to the traditional algorithm based on the comparison between the average of the measured Cherenkov angles and the expected Cherenkov angles of the photons generated in the RICH by the particle to be identified. On the other hand it is much simpler and faster than a full likelihood analysis of the full event pattern. The particle rejection ratios achievable with the combined use of this algorithm and the algorithm based on the comparison between the average and the expected Cherenkov angles are very high. The algorithm also allows one to identify noise easily. The application of the algorithm is shown for the Hall A RICH detector in the E94-107 experiment at JLab. In this experiment an enormous background made up of pions and protons is 30 000 times bigger than the signal and had to be identified and rejected in order to extract the kaons from the electroproduction of hypernuclei.

AB The crystal growth and scintillation properties of Ba(2)Csl(5):Eu2+ are reported. Crystals were produced by the vertical Bridgman technique in a sealed quartz ampoule. Ba(2)Csl(5):Eu2+ presents excellent scintillation properties. An estimated light yield of 97,000 +/- 5,000 photons per MeV (ph/MeV) of absorbed gamma-ray energy was measured. An energy resolution (FWHM over peak position) of 3.8 +/- 0.3% was observed for the 662 keV full absorption peak. Pulsed X-ray luminescence measurements show a relatively complex time response with four exponential decay components of 48,383, 1500 and 9900 ns with a contribution to the total light output of 1%, 26%, 68% and 25%, respectively. Under X-ray and UV excitation, the emission corresponds to a broadband centered at 2.85 eV. First principles calculations show strong localization of the excited state on the Eu site. Ba(2)Csl(5):Eu2+ has a density of about 5 g/cm(3). These first reported scintillation properties make Ba(2)Csl(5):Eu2+ a very high-performance scintillator. Published by Elsevier B.V.

ID THERMAL-NEUTRONS
AB Various neutron detectors are being developed for the next generation user facilities, which incorporate new as well as existing approaches for the detection of thermal neutrons. Improvements in neutron detector efficiency, detector size and position resolution have occurred over the last three decades and further advances are expected in the next ten years. Since gas detectors are expected to continue in a key role for future thermal neutron experiments, it is advantageous to review some of the criteria for the choice of proton/triton stopping gases for gas-based detectors. Monte Carlo simulations, using the group of programs "Stopping and Range of Ions in Matter", have been run to determine key performance characteristics for neutron detectors which utilize the reaction (3)He(n,p)t. This paper will focus on investigating the use of three common hydrocarbons and CF(4) as stopping gases for thermal neutron detectors. A discussion of these gases will include their behavior in terms of proton and triton range, ion distribution and straggle. (C) 2009 Elsevier B.V. All rights reserved.

AB We have demonstrated broad bandwidth large area (229 mm x 114 mm) multilayer dielectric diffraction gratings for the efficient compression of high energy 800 nm laser pulses at high average power. The gratings are etched in the top layers of an aperiodic (Nb0.5Ta0.5)(2)O-5-SiO2 multilayer coating deposited by ion beam sputtering. The mean efficiency of the grating across the area is better than 97% at the center wavelength and remains above 96% at wavelengths between 820 nm and 780 nm. The gratings were used to compress 5.5 J pulses from a Ti:sapphire laser with an efficiency above 80 percent. (C) 2009 Optical Society of America

AB Extracting endmembers from remotely-sensed images of vegetated areas can present difficulties. In this research, we applied a recently-developed endmember-extraction algorithm based on Support Vector Machines to the problem of semi-autonomous estimation of vegetation endmembers from a hyperspectral image. This algorithm, referred to as Support Vector Machine-Based Endmember Extraction (SVM-BEE), accurately and rapidly yields a computed representation of hyperspectral data that can accommodate multiple distributions. The number of distributions is identified without prior knowledge, based upon this representation. Prior work established that SVM-BEE is robustly noise-tolerant and can semi-automatically estimate endmembers; synthetic data and a geologic scene were previously analyzed. Here we compared the efficacies of SVM-BEE, N-FINDR, and SMACC algorithms in extracting endmembers from a real, predominantly-agricultural scene. SVM-BEE estimated vegetation and other endmembers for all classes in the image, which N-FINDR and SMACC failed to do. SVM-BEE was consistent in the endmembers that it estimated across replicate trials. Spectral angle mapper (SAM) classifications based on SVM-BEE-estimated endmembers were significantly more accurate compared with those based on N-FINDR- and (in general) SMACC-endmembers. Linear spectral unmixing accrued overall accuracies similar to those of SAM. (C) 2009 Optical Society of America

AB The objective of this work is to establish an optical imaging technique that would enable monitoring of the integration of mesenchymal stem cells (MSC) in arthritic joints. Our approach is based on first developing a labeling technique of MSC with the fluorescent dye DiD followed by tracking the cell migration kinetics from the spatial distribution of the DiD fluorescence in optical images (OI). The experimental approach involves first the in vitro OI of MSC labeled with DiD accompanied by fluorescence microscopy measurements to establish localization of the signal within the cells. Thereafter, DiD-labeled MSC were injected into polyarthritic, athymic rats and the signal localization within the experimental animals was monitored over several days. The experimental results indicate that DiD integrated into the cell membrane. DiD-labeled MSC localization in the arthritic ankle joints was observed with OI indicating that this method can be applied to monitor MSC in arthritic joints. (C) 2009 Optical Society of America

AB In our Galaxy there are 64 Be X-ray binaries known to date. Out of these, 42 host a neutron star (NS), and for the remainder the nature of the companion is unknown. None, so far, are known to host a black hole (BH). There seems to be no apparent mechanism that would prevent formation or detection of Be stars with BHs. This disparity is referred to as a missing Be-BH X-ray binary problem. We point out that current evolutionary scenarios that lead to the formation of Be X-ray binaries predict that the ratio of binaries with NSs to the ones with BHs is rather high, F-NStoBH similar to 10-50, with the more likely formation models providing the values at the high end. The ratio is a natural outcome of (1) the stellar initialmass function that produces more NSs than BHs and (2) common envelope evolution (i.e., a major mechanism involved in the formation of interacting binaries) that naturally selects progenitors of Be X-ray binaries with NSs (binaries with comparable mass components have more likely survival probabilities) over ones with BHs (which are much more likely to be common envelope mergers). A comparison of this ratio (i.e., F-NStoBH similar to 30) with the number of confirmed Be-NS X-ray binaries (42) indicates that the expected number of Be-BH X-ray binaries is of the order of only similar to 0-2. This is entirely consistent with the observed Galactic sample.

AB We present Hubble Space Telescope optical coronagraphic polarization imaging observations of the dusty debris disk HD 61005. The scattered light intensity image and polarization structure reveal a highly inclined disk with a clear asymmetric, swept back component, suggestive of significant interaction with the ambient interstellar medium (ISM). The combination of our new data with the published 1.1 mu m discovery image shows that the grains are blue scattering with no strong color gradient as a function of radius, implying predominantly submicron- sized grains. We investigate possible explanations that could account for the observed swept back, asymmetric morphology. Previous work has suggested that HD 61005 may be interacting with a cold, unusually dense interstellar cloud. However, limits on the intervening interstellar gas column density from an optical spectrum of HD 61005 in the Na I D lines render this possibility unlikely. Instead, HD 61005 may be embedded in a more typical warm, low-density cloud that introduces secular perturbations to dust grain orbits. This mechanism can significantly distort the ensemble disk structure within a typical cloud crossing time. For a counterintuitive relative flow direction-parallel to the disk midplane-we find that the structures generated by these distortions can very roughly approximate the HD 61005 morphology. Future observational studies constraining the direction of the relative ISM flow will thus provide an important constraint for future modeling. Independent of the interpretation for HD 61005, we expect that interstellar gas drag likely plays a role in producing asymmetries observed in other debris disk systems, such as HD 15115 and delta Velorum.

AB We have used the zCOSMOS-bright 10k sample to identify 3244 Spitzer/MIPS 24 mu m-selected galaxies with 0.06 mJy < S-24 mu m less than or similar to 0.50 mJy and I-AB < 22.5, over 1.5 deg(2) of the COSMOS field, and studied different spectral properties, depending on redshift. At 0.2 < z < 0.3, we found that different reddening laws of common use in the literature explain the dust extinction properties of similar to 80% of our infrared (IR) sources, within the error bars. For up to 16% of objects, instead, the H alpha lambda 6563/H beta lambda 4861 ratios are too high for their IR/UV attenuations, which is probably a consequence of inhomogeneous dust distributions. In only a few of our galaxies at 0.2 < z < 0.3, the IR emission could be mainly produced by dust heated by old rather than young stars. Besides, the line ratios of similar to 22% of our galaxies suggest that they might be star-formation/nuclear-activity composite systems. At 0.5 < z < 0.7, we estimated galaxy metallicities for 301 galaxies: at least 12% of them are securely below the upper-branch mass-metallicity trend, which is consistent with the local relation. Finally, we performed a combined analysis of the H-delta equivalent width versus D-n (4000) diagram for 1722 faint and bright 24 mu m galaxies at 0.6 < z < 1.0, spanning two decades in mid-IR luminosity. We found that, while secondary bursts of star formation are necessary to explain the position of the most luminous IR galaxies in that diagram, quiescent, exponentially declining star formation histories can well reproduce the spectral properties of similar to 40% of the less luminous sources. Our results suggest a transition in the possible modes of star formation at total IR luminosities L-TIR approximate to (3 +/- 2) x 10(11) L-circle dot.

AB We present a new analysis of stellar mass functions in the COSMOS field to fainter limits than has been previously probed at z <= 1. The increase in dynamic range reveals features in the shape of the stellar mass function that deviate from a single Schechter function. Neither the total nor the red (passive) or blue (star-forming) galaxy stellar mass functions can be well fitted with a single Schechter function once the mass completeness limit of the sample probes below similar to 3 x 10(9) M(circle dot). We observe a dip or plateau at masses similar to 10(10) M(circle dot), just below the traditional M*, and an upturn toward a steep faint-end slope of alpha similar to -1.7 at lower mass at all redshifts <= 1. This bimodal nature of the mass function is not solely a result of the blue/red dichotomy. Indeed, the blue mass function is by itself bimodal at z similar to 1. This suggests a new dichotomy in galaxy formation that predates the appearance of the red sequence. We propose two interpretations for this bimodal distribution. If the gas fraction increases toward lower mass, galaxies with M(baryon) similar to 10(10) M(circle dot) would shift to lower stellar masses, creating the observed dip. This would indicate a change in star formation efficiency, perhaps linked to supernovae feedback becoming much more efficient below similar to 10(10) M(circle dot). Therefore, we investigate whether the dip is present in the baryonic (stars+gas) mass function. Alternatively, the dip could be created by an enhancement of the galaxy assembly rate at similar to 10(11) M(circle dot), a phenomenon that naturally arises if the baryon fraction peaks at M(halo) similar to 10(12) M(circle dot). In this scenario, galaxies occupying the bump around M(*) would be identified with central galaxies and the second fainter component of the mass function having a steep faint-end slope with satellite galaxies. The low-mass end of the blue and total mass functions exhibit a steeper slope than has been detected in previous work that may increasingly approach the halo mass function value of -2. While the dip feature is apparent in the total mass function at all redshifts, it appears to shift from the blue to the red population, likely as a result of transforming high-mass blue galaxies into red ones. At the same time, we detect a drastic upturn in the number of low-mass red galaxies. Their increase with time seems to reflect a decrease in the number of blue systems and so we tentatively associate them with satellite dwarf (spheroidal) galaxies that have undergone quenching due to environmental processes.

AB This paper presents a numerical study over a wide parameter space of the likelihood of dynamical bar-mode instability in differentially rotating magnetized neutron stars. The innovative aspect of this study is the incorporation of magnetic fields in such a context, which have thus far been neglected in the purely hydrodynamical simulations available in the literature. The investigation uses the Cosmos++ code which allows us to perform three-dimensional simulations on a cylindrical grid at high resolution. A sample of Newtonian magnetohydrodynamical simulations starting from a set of models previously analyzed by other authors without magnetic fields has been performed, providing estimates of the effects of magnetic fields on the dynamical bar-mode deformation of rotating neutron stars. Overall, our results suggest that the effect of magnetic fields is not likely to be very significant in realistic configurations. Only in the most extreme cases are the magnetic fields able to suppress growth of the bar mode.

AB We develop a fully implicit scheme for the Navier-Stokes equations, in conservative form, for low to intermediate Mach number flows. Simulations in this range of flow regime produce stiff wave systems in which slow dynamical (advective) modes coexist with fast acoustic modes. Viscous and thermal diffusion effects in refined boundary layers can also produce stiffness. Implicit schemes allow one to step over the fast wave phenomena (or unresolved viscous time scales), while resolving advective time scales. In this study we employ the Jacobian-free Newton-Krylov (JFNK) method and develop a new physics-based preconditioner. To aid in overcoming numerical stiffness caused by the disparity between acoustic and advective modes, the governing equations are transformed into the primitive-variable form in a preconditioning step. The physics-based preconditioning incorporates traditional semi-implicit and physics-based splitting approaches without a loss of consistency between the original and preconditioned systems. The resulting algorithm is capable of solving low-speed natural circulation problems (M similar to 10(-4)) with significant heat flux as well as intermediate speed (M similar to 1) flows efficiently by following dynamical (advective) time scales of the problem.

AB The spin and valence states of iron in (Mg0.8Fe0.2) SiO3 perovskite were measured between 0 and 65 GPa using synchrotron Mossbauer spectroscopy. Samples were synthesized in situ in the laser-heated diamond cell under reducing conditions. The dominant spin state of iron in perovskite is high spin at pressures below 50 GPa. Above 50 GPa, the spectra shows severe changes which can be explained by appearance of two distinct iron sites with similar site weightings. One site has Mossbauer parameters consistent with high spin Fe2+, while the other has the parameters previously interpreted as intermediate spin. The latter intermediate-spin assignment is not unique, as similar Mossbauer parameters have been reported for high spin Fe2+ in almandine at ambient pressure. However, our data do not rule out the existence of low-spin iron, which may exist with a smaller fraction and explain the observation of lower spin moments in the X-ray emission spectroscopy of perovskite at high pressure. From these considerations, our preferred interpretation is that iron in perovskite is mixed or high spin to at least 2000 km depths in the mantle, consistent with computational results. Our study also reveals that reducing conditions do not inhibit the formation of Fe3+ in perovskite at deep-mantle pressures. Citation: Grocholski, B., S.-H. Shim, W. Sturhahn, J. Zhao, Y.

ID HEAVY-ION COLLISIONS; NUCLEAR COLLISIONS; HOT QCD
AB Parity-odd domains, corresponding to nontrivial topological solutions of the QCD vacuum, might be created during relativistic heavy-ion collisions. These domains are predicted to lead to charge separation of quarks along the system's orbital momentum axis. We investigate a three-particle azimuthal correlator which is a P even observable, but directly sensitive to the charge separation effect. We report measurements of charged hadrons near center-of-mass rapidity with this observable in Au+Au and Cu+Cu collisions at s(NN)=200 GeV using the STAR detector. A signal consistent with several expectations from the theory is detected. We discuss possible contributions from other effects that are not related to parity violation.

TI Search for Invisible Decays of the Upsilon(1S)
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
AB We search for invisible decays of the Upsilon(1S) meson using a sample of 91.4x10(6) Upsilon(3S) mesons collected at the BABAR/PEP-II B factory. We select events containing the decay Upsilon(3S)->pi(+)pi(-)Upsilon(1S) and search for evidence of an undetectable Upsilon(1S) decay recoiling against the dipion system. We set an upper limit on the branching fraction B(Upsilon(1S)-> invisible)< 3.0x10(-4) at the 90% confidence level.

TI Interstitial-Mediated Diffusion in Germanium under Proton Irradiation
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID IMPLANTATION; VACANCY; BORON; GE
AB We report experiments on the impact of 2.5 MeV proton irradiation on self-diffusion and dopant diffusion in germanium (Ge). Self-diffusion under irradiation reveals an unusual depth independent broadening of the Ge isotope multilayer structure. This behavior and the observed enhanced diffusion of B and retarded diffusion of P demonstrates that an interstitial-mediated diffusion process dominates in Ge under irradiation. This fundamental finding opens up unique ways to suppress vacancy-mediated diffusion in Ge and to solve the donor deactivation problem that hinders the fabrication of Ge-based nanoelectronic devices.

TI Real-Time Observation of Reactive Spreading of Gold on Silicon
SO PHYSICAL REVIEW LETTERS

DT Article
ID SURFACE-DIFFUSION; SI NANOWIRES; SI(111); TRANSITION; MIGRATION;
DYNAMICS; W(110); AU
AB The spreading of a bilayer gold film propagating outward from gold clusters, which are pinned to clean Si(111), is imaged in real time by low-energy electron microscopy. By monitoring the evolution of the boundary of the gold film at fixed temperature, a linear dependence of the spreading radius on time is found. The measured spreading velocities in the temperature range of 800 < T < 930 K varied from below 100 pm/s to 50 nm/s. We show that the spreading rate is limited by the reaction to form Au silicide, and the spreading velocity is likely regulated by the reconstruction of the gold silicide that occurs at the interface.

TI Two-Electron Time-Delay Interference in Atomic Double Ionization by
Attosecond Pulses
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID AUGER; PHOTOELECTRON
AB A two-color two-photon atomic double ionization experiment using subfemtosecond uv pulses can be designed such that the sequential two-color process dominates and one electron is ejected by each pulse. Nonetheless, ab initio calculations show that, for sufficiently short pulses, a prominent interference pattern in the joint energy distribution of the sequentially ejected electrons can be observed that is due to their indistinguishability and the exchange symmetry of the wave function.

TI Spin-Order Driven Fermi Surface Reconstruction Revealed by Quantum
Oscillations in an Underdoped High T-c Superconductor
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID STATE; PHYSICS
AB We use quantum oscillation measurements to distinguish between spin and orbital components of the lowest energy quasiparticle excitations in YBa2Cu3O6.54, each of which couple differently to a magnetic field. Our measurements reveal the phase of the observed quantum oscillations to remain uninverted over a wide angular range, indicating that the twofold spin degeneracy of the Landau levels is virtually unaltered by the magnetic field. The inferred suppression of the spin degrees of freedom indicates a spin-density wave is responsible for creation of the small Fermi surface pockets in underdoped YBa2Cu3O6+x-further suggesting that excitations of this phase are important contributors to the unconventional superconducting pairing mechanism.

AB We present the first fully kinetic, collisional, and electromagnetic simulations of the complete time evolution of a deuterium gas puff z pinch. Recent experiments with 15-MA current pinches have suggested that the dominant neutron-production mechanism is thermonuclear. We observe distinct differences between the kinetic and magnetohydrodynamic simulations in the pinch evolution with the kinetic simulations producing both thermonuclear and beam-target neutrons. The kinetic approach demonstrated in this Letter represents a viable alternative for performing future plasma physics calculations.

TI The structure of pyogenecin immunity protein, a novel bacteriocin-like
immunity protein from Streptococcus pyogenes
SO BMC STRUCTURAL BIOLOGY

CRYSTAL-STRUCTURE; GENETIC-CHARACTERIZATION; ANTIMICROBIAL SPECTRUM;
LIPID MICELLES; CIRCULARIN-A; CURVACIN-A; 2 PEPTIDES
AB Background: Many Gram-positive lactic acid bacteria (LAB) produce anti-bacterial peptides and small proteins called bacteriocins, which enable them to compete against other bacteria in the environment. These peptides fall structurally into three different classes, I, II, III, with class IIa being pediocin-like single entities and class IIb being two-peptide bacteriocins. Self-protective cognate immunity proteins are usually co-transcribed with these toxins. Several examples of cognates for IIa have already been solved structurally. Streptococcus pyogenes, closely related to LAB, is one of the most common human pathogens, so knowledge of how it competes against other LAB species is likely to prove invaluable.
Results: We have solved the crystal structure of the gene-product of locus Spy_ 2152 from S. pyogenes, (PDB:2fu2), and found it to comprise an anti-parallel four-helix bundle that is structurally similar to other bacteriocin immunity proteins. Sequence analyses indicate this protein to be a possible immunity protein protective against class IIa or IIb bacteriocins. However, given that S. pyogenes appears to lack any IIa pediocin-like proteins but does possess class IIb bacteriocins, we suggest this protein confers immunity to IIb-like peptides.
Conclusions: Combined structural, genomic and proteomic analyses have allowed the identification and in silico characterization of a new putative immunity protein from S. pyogenes, possibly the first structure of an immunity protein protective against potential class IIb two-peptide bacteriocins. We have named the two pairs of putative bacteriocins found in S. pyogenes pyogenecin 1, 2, 3 and 4.

AB Details of the first-shell water structure about Ag(+) are reported from a corefinement of the K- and L(2)-edge multiple scattering signal in the X-ray absorption fine Structure (XAFS) spectra Detailed fits of the Ag K-edge data that include the contributions from multiple scattering processes in the hydrated ion structure cannot distinguish between models containing tetrahedral symmetry versus those containing collinear O-Ag-O bonds. However, we show that the multiple scattering oscillations at the L(2)-edges have distinctly different phase and amplitude functions than at the K-edge. These phase and amplitude functions depend not only oil the symmetry of the multiple scattering paths but also Oil the nature of the final state electronic wave function probed by the dipole-allowed transition. Hence the multiple scattering portions of K- and L(2)-edge spectra provide independent measurements of the local symmetry-not it redundant measurement as is commonly believed Oil the basis of the enhanced information content obtained by the Simultaneous assessment of both the K- and L(2)-edges, we report that the hydrated Ag(+) structure contains five or six water molecules ill the first shell with it significant number of nearly collinear and 90 degrees O-Ag-O bond angles. Finally, the K- and L(2)-edge spectra ire used to benchmark the hydration structure that is generated from both DFT-based and classical molecular dynamics simulations. Simulated first-shell structures are compared to the experimental structures.

AB We report reversible thermochromism of a conjugated polymer, poly {2,5-bis[3-(N,N-diethylamino)-1-oxapropyl]-1,4-phenylenevinylene} (DAO-PPV), in diluted solutions Of toluene and 1,2-dichlorobenzene. By means of temperature- and solvent-dependent steady-state spectroscopy, picosecond time-resolved photoluminescence spectroscopy, and dynamic light scattering, we provide new insights into the role of polymer aggregates in defining the thermochromic behavior of PPVs. We find DAO-PPV to exhibit a low temperature state with vibronically Structured red visible absorption and emission spectra. Structurally, this low temperature state is a densely packed and disordered polymer aggregate, which contains a fraction of well-ordered, packed polymer chains. These ordered regions serve its low energy trap sites for the more disordered regions in the aggregate, thus regulating the final emission of the aggregate and imposing a vibronically resolved emission spectrum, which is usually associated with emission from one or a few chromophores. The high temperature state of DAO-PPV is a loose aggregate, with structureless absorption and emission spectra in the green visible range, Structurally, the loose aggregate is a well-solvated aggregate retaining the physical dimension of the dense aggregate but for which interchain interactions are diminished with the increase of temperature. As a result, the spectroscopic behavior of the loose aggregate is very similar if not identical to that of the single polymer chain. Increased Solubility untangles polymer aggregates into single, dispersed, polymer chains, as we demonstrate here for DAO-PPV in 1,2-dichlorobenzene and at high temperature.

AB New approach for synthesis of Co2+ doped TiO2 nanoparticles showing room temperature ferromagnetic behavior, through shape transformation of hydrothermally treated scrolled titania nanotubes in the presence of Co2+ ions is described. The XRD and ICP measurements demonstrated successful incorporation of 0.46 at % Co2+ ions in preserved anatase crystal structure of TiO2 nanoparticles, without presence of Co-oxide Clustering, metallic Co, or Various Co-Ti oxide species. HRTEM measurements revealed that majority of the nanoparticles have polygonal shapes with average dimension of similar to 6-10 nm. Obtained Value of 3.06 eV for band gap energy of Co2+ doped TiO2 nanoparticles explained altered optical properties of TiO2 matrix and indicates narrowing of the electronic properties in respect to the undoped anatase TiO2 nanomaterials. The Co2+ doped TiO2 nanocrystals enabled synthesis of optically transparent film that shows room temperature ferromagnetic ordering with a saturation magnetic moment of 0 25 mu B per Co atom The proposed explanation for room temperature ferromagnetic behavior is based oil the presence of critical amount of oxygen vacancies that mediate interaction between Co2+ spins trapped in the lattice Structure of titania nanoparticles with undercoordinated surface defect sites.

AB The desulfation of presulfated Pt-BaO/CeO2) lean NOx trap catalyst was investigated by H-2 TPRX (temperature programmed reaction), in situ TR-XRD (time-resolved X-ray diffraction), and in situ S K-edge XANES (Xray absorption near edge spectroscopy) techniques Compared with Pt-BaO/Al2O3 materials, I reductive treatment in H-2 for the CeO2-supported sample up to 1073 K removes, at most, only a very small amount of sulfur species. However, the results Of in Situ TR-XRD measurements demonstrate that the quantity of a BaS phase formed oil Pt-BaO/CeO2 IS Much smaller than that on Pt-BaO/Al2O3, implying that the formation of BaS crystallites. which Occurs during the reduction from Sulfate (SO42-) to sulfide (S2-), is significantly Suppressed in the CeO2-supported catalyst. As the desulfation temperature increases under reducing Conditions (m H-2), in Situ S XANES spectra show that. compared with alumina-supported samples, the reduction temperature for Sulfates (S6+) decreases by about 150 K. Concomitantly, the formation Of Sulfur species with lower oxidation states (SI-S') is enhanced The absolute intensities of S XANES spectra before and after desulfation are very similar, implying that the amount of sulfur-contaming species removed during the reductive treatment is negligible, in agreement with the results of H-2 TPRX These results Suggest that H2S produced by the reduction of BaSO4 is readily readsorbed oil the ceria support to form ceria-sulfur complexes (e.g., Ce2O2S) The high affinity of ceria for H2S, combined with the ease of reducibility of the ceria support material gives rise to Various oxidation states of sulfur after high-temperature H-2 treatments. Thus, the results of this study clearly show that the ceria Support strongly affects the overall desulfaction mechanism. The intrinsic role of the ceria support during desulfation and its effect oil the overall NOx storage processes are discussed oil the basis of the characterization results obtained here.

AB We report inelastic and elastic neutron scattering, magnetic susceptibility, and heat capacity measurements for polycrystalline sodium ruthenate (Na3RuO4). Previous work suggests that this material consists of isolated tetramers of S = 3/2 Ru5+ ions in a so-called lozenge configuration. Comparisons of magnetic susceptibility and inelastic and elastic neutron scattering results with analytic calculations for several cluster models show that although there may be significant spin-spin correlations within the lozenge cluster, a simple isolated lozenge model is not appropriate for Na3RuO4.

AB The composition and microstructure of five thermoelectric materials, PbTe, SnTe, Pb0.65Sn0.35Te and NaPb18-xSnxBiTe20 (x = 5, 9), were investigated by advanced transmission electron microcopy. We confirm that the pure PbTe, SnTe, and Pb0.65Sn0.35Te have a uniform crystalline structure and homogeneous compositions without any nanoscale inclusions. On the other hand, the nominal NaPb9Sn9BiTe20 phase contains extensive inhomogeneities and nanostructures with size distribution of 3-7 nm. We find that the chemical architecture of the NaPb13Sn5BiTe20 member of the series to be more complex; besides nanoscale precipitates, self-organized lamellar structures are present which were identified as PbTe and SnTe by composition analysis and transmission electron microscopy image simulations. Density functional theory calculations suggest that the arrangement of the lamellar structures conforms to the lowest total energy configuration. Geometric-phase analyses revealed large distributed elastic strain around the nanoscale inclusions and lamellar structures. We propose that interface-induced elastic perturbations in the matrix play a decisive role in affecting the phonon-propagation pathways. The interfaces further enhance phonon scattering which, in turn, reduces the lattice thermal conductivity in these systems that directly results directly in improvement in the thermoelectric figure of merit.

AB We present the first scanning tunneling microscopy (STM) study of the rotational dynamics of organic species on any oxide surface. Specifically, variable-temperature STM and dispersion-corrected density functional theory (DFT-D) are used to study the alkyl chain conformational disorder and dynamics of 1-, 2-, 3- and 4-octoxy on rutile TiO2(110). Initially, the geminate pairs of the octoxy and bridging hydroxyl species are created via octanol dissociation on bridging-oxygen (O-b) vacancy defects. The STM images provide time-averaged snapshots of octoxy species rotating among multiple energetically nearly degenerate configurations accessible at a given temperature. In the calculations we find that the underlying corrugated potential energy surface is a result of the interplay between attractive van der Waals dispersion forces, leading to weak attractive C center dot center dot center dot Ti and repulsive C center dot center dot center dot O-b interactions which lead to large barriers of 50-70 kJ mol(-1) for the rotation of the octoxy alkyl chains across the O-b rows. In the presence of the geminate hydroxyl groups we find that the relative populations of the various conformations as well as the rotational barriers are perturbed by the presence of geminate hydroxyl due to additional C center dot center dot center dot hydroxyl repulsions.

AB A new method for producing long, small-diameter, single- and few-walled, boron nitride nanotubes (BNNTs) in macroscopic quantities is reported. The pressurized vapor/condenser (PVC) method produces, without catalysts, highly crystalline, very long, small-diameter, BNNTs. Palm-sized, cotton-like masses of BNNT raw material were grown by this technique and spun directly into centimeters-long yarn. Nanotube lengths were observed to be 100 times that of those grown by the most closely related method. Self-assembly and growth models for these long BNNTs are discussed.

AB identifying and characterizing protein interactions are fundamental steps toward understanding and modeling biological networks. Methods that detect protein interactions in intact cells rather than buffered solutions are likely more relevant to natural systems since molecular crowding events in the cytosol can influence the diffusion and reactivity of individual proteins. One in vivo, imaging-based method relies on the colocalization of two proteins of interest fused to DivIVA, a cell division protein from Bacillus subtilis, and green fluorescent protein (GFP). We have modified this imaging-based assay to facilitate rapid cloning by constructing new vectors encoding N- and C-terminal DivIVA or GFP molecular tag fusions based on site-specific recombination technology. The sensitivity of the assay was defined using a well-characterized protein interaction system involving the eukaryotic nuclear import receptor subunit, Importin alpha (Imp alpha), and variant nuclear localization signals (NLS) representing a range of binding affinities. These data demonstrate that the modified colocalization assay is sensitive enough to detect protein interactions with K(d) values that span over tour orders of magnitude (1 nM to 15 mu M). Lastly, this assay was used to confirm numerous protein interactions identified from mass spectrometry-based analyses of affinity isolates as part of an interactome mapping project in Rhodopseudomonas palustris.

AB An exoelectrogenic, biofilm-forming microbial consortium was enriched in an acetate-fed microbial fuel cell (MFC) using a flow-through anode coupled to an air-cathode. An MFC design with low electrode spacing, high specific electrode surface area with minimal dead volume and control of external resistance was used. In addition, continuous feeding of carbon source was employed and the MFC was operated at intermittent high flows to enable removal of non-biofilm-forming organisms over a period of 6 months. The consortium enriched using the modified design and operating conditions resulted in a power density of 345 W m(-3) of net anode volume (3650 mW m(-2)), when coupled to a ferricyanide cathode. The enriched consortium included beta, del, gamma-Proteobacteria, Bacteroidetes and Firmicutes. Members of the order Rhodocyclaceae and Burkholderiaceae (Azospira sp. (49%), Acidovorax sp. (11%) and Comamonas sp. (7%)), dominated the microbial consortium. Denaturing gradient gel electrophoresis (DGGE) analysis based on primers selective for archaea indicated presence of very few methanogens. Limiting the delivery of the carbon source via continuous feeding corresponding to the maximum cathodic oxidation rates permitted in the flow-through, air-cathode MFC resulted in coulombic efficiencies reaching 88 +/- 5.7%.

AB Direct electrochemistry of a glucose oxidase (GOD)-graphene-chitosan nanocomposite was studied. The immobilized enzyme retains its bioactivity, exhibits a surface confined, reversible two-proton and two-electron transfer reaction, and has good stability, activity and a fast heterogeneous electron transfer rate with the rate constant (k(s)) of 2.83 s(-1). A much higher enzyme loading (1.12 x 10(-9) mol/cm(2)) is obtained as compared to the bare glass carbon surface. This GOD-graphene-chitosan nanocomposite film can be used for sensitive detection of glucose. The biosensor exhibits a wider linearity range from 0.08 mM to 12 mM glucose with a detection limit of 0.02 mM and much higher sensitivity (37.93 mu A mM(-1) cm(-2)) as compared with other nanostructured supports. The excellent performance of the biosensor is attributed to large surface-to-volume ratio and high conductivity of graphene, and good biocompatibility of chitosan, which enhances the enzyme absorption and promotes direct electron transfer between redox enzymes and the surface of electrodes.

AB Biomolecular motors, such as kinesin, have been used to shuttle a range of biological and synthetic cargo in microfluidic architectures. A critical gap in this technology is the ability to controllably link macromolecular cargo on microtubule (MT) shuttles without forming extraneous byproducts that may potentially limit their application. Here we present a generalized approach for functionalizing MTs with antibodies in which covalent bonds are formed between the carbohydrate in F(c) region of polyclonal antibodies and the positively charged amino acids on the MT surface using the crosslinker succinimidyl 4-hydrazidoterephthalate hydrochloride (SHTH). Antibody-functionalized MTs (Ab-MTs) produced through this approach maintained motility characteristics and antigenic selectivity, and did not produce undesirable byproducts common to other approaches. We also demonstrate and characterize the application of these Ab-MTs for capturing and transporting bacterial and viral antigens. While this approach cannot be applied to monoclonal antibodies, which lack a carbohydrate moiety, it may be used for selectively functionalizing MT shuttles with a variety of carbohydrate-containing cargoes.

AB A study of U(VI) adsorption by aquifer sediment samples from a former uranium mill tailings site at Rifle, Colorado, was conducted under oxic conditions as a function of pH, U(VI), Ca, and dissolved carbonate concentration. Batch adsorption experiments were performed using <2 mm size sediment fractions, a sand-sized fraction, and artificial groundwater solutions prepared to simulate the field groundwater composition. To encompass the geochemical conditions of the alluvial aquifer at the site, the experimental conditions ranged from 6.8 x 10(-8) to 10(-5) M in [U(VI)](tot), 7.2 to 8.0 in pH, 3.0 x 10(-3) to 6.0 x 10(-3) M in [Ca2+], and 0.05 to 2.6% in partial pressure of carbon dioxide. Surface area normalized U(VI) adsorption K-d values for the sand and <2 mm sediment fraction were similar, suggesting a similar reactive surface coating on both fractions. A two-site two-reaction, nonelectrostatic generalized composite surface complexation model was developed and successfully simulated the U(VI) adsorption data. The model successfully predicted U(VI) adsorption observed from a multilevel sampling well installed at the site. A comparison of the model with the one developed previously for a uranium mill tailings site at Naturita, Colorado, indicated that possible calcite nonequilibrium of dissolved calcium concentration should be evaluated. The modeling results also illustrate the importance of the range of data used in deriving the best fit model parameters.

Fate in Phytoremediation
SO ENVIRONMENTAL SCIENCE & TECHNOLOGY

AB Phytoremediation of volatile organic contaminants often proves not ideal because plants and their rhizosphere microbes only partially degrade these compounds. Consequently, plants undergo evapotranspiration that contaminates the ambient air and, thus, undermines the merits of phytoremediation. Under laboratory conditions, endophytic bacteria equipped with the appropriate degradation pathways can improve in planta degradation of volatile organic contaminants. However, several obstacles must be overcome before engineered endophytes will be successful in field-scale phytoremediation projects. Here we report the first in situ inoculation of poplar trees, growing on a TCE-contaminated site, with the TCE-degrading strain Pseudomonas putida W619-TCE. In situ bioaugmentation with strain W619-TCE reduced TCE evapotranspiration by 90% under field conditions. This encouraging result was achieved after the establishment and enrichment of P. putida W619-TCE as a poplar root endophyte and by further horizontal gene transfer of TCE metabolic activity to members of the poplars endogenous endophytic population. Since P. putida W619-TCE was engineered via horizontal gene transfer, its deliberate release is not restricted under European genetically modified organisms (GMO) regulations.

AB In this paper we report the results of a study using small angle and ultra-small angle neutron scattering techniques (SANS and USANS) to examine the evolution of carbonates during contact metamorphism. Data were obtained from samples collected along two transects in the metamorphosed Hueco limestone at the Marble Canyon, Texas, contact aureole. These samples were collected from the igneous contact out to similar to 1700 m. Scattering curves obtained from these samples show mass fractal behavior at low scattering vectors, and surface fractal behavior at high scattering vectors. Significant changes are observed in the surface and mass fractal dimensions as well as the correlation lengths (pore and grain sizes), surface area to volume ratio and surface Gibbs Free energy as a function of distance, including regions of the aureole outside the range of classic metamorphic petrology. A change from mass-fractal to non-fractal behavior is observed at larger scales near the outer boundary of the aureole that implies significant reorganization of pore distributions early in the metamorphic history. Surface fractal results suggest significant smoothing of grain boundaries, coupled with changes in pore sizes. A section of the scattering Curve with a slope less than -4 appears Lit low-Q in metamorphosed samples, which is not present in unmetamorphosed samples. A strong spike in the surface area to volume ratio is observed in rocks near the mapped metamorphic limit, which is associated with reaction of small amounts of organic material to graphite. It may also represent an increase in pore Volume or permeability, suggesting that a high permeability zone forms at the boundary of the aureole and moves outwards as metamorphism progresses. Neutron scattering data also correlate well with transmission electron microscopic (TEM) observations, which show formation of micro- and nanopores and microfractures during metamorphism. The scattering data are, however, quantifiable for a bulk rock in a manner that is difficult to achieve using high-resolution imaging (e.g. TEM). Thus, neutron scattering techniques provide a new approach to the analysis and study of metamorphism. (C) 2009 Elsevier Ltd. All rights reserved.

AB Liquid phase diffusion experiments were carried out to determine whether diffusive isotopic fractionation of a major chemical element (Ca) varies with chemical composition in high-temperature molten silicates. The objective was to determine how differences in silicate liquid structure, such as the ratio of bridging to non-bridging oxygen atoms, as well as bulk transport properties such as viscosity, relate to isotope discrimination during diffusion. This information, in turn, may relate to the lifetimes and sizes of multi-atom structures in the liquid. Diffusion couples consisting of juxtaposed natural mafic and felsic liquids were held at T = 1450 degrees C and P = 1.0 GPa for durations of 12-24 h in a standard piston-cylinder assembly. Experiments were done using different mafic endmember compositions (two tholeiitic basalts and a ugandite) and a single rhyolite composition. Major-element diffusion profiles and Ca isotope profiles were measured on the recovered quenched glasses. The starting materials were isotopically indistinguishable, but (44)Ca/(40)Ca variations of ca. 5 parts per thousand arose due to a mass dependence of the Ca diffusion coefficients. Results indicate that the mass dependence of Ca diffusion coefficients varies with the magnitude and direction of aluminum gradients and the viscosity of the liquid. Some Ca fractionations result mainly from Al gradients.
A simplified multicomponent diffusion model was used to model the experimental results. The model allows for diffusion of Ca in response to gradients in the concentrations of both CaO as well as Al(2)O(3), and the model results are consistent with the inferred existence of at least two distinct species of Ca. The magnitude of isotopic discrimination during diffusion also appears to be stronger on the rhyolite versus the basalt/ugandite side of diffusion couples. The results can largely be accounted for by an adaptation of the model of Dingwell (1990), whereby in high silica liquids, Ca diffuses largely by site hopping through a quasi-stationary aluminosilicate matrix, producing strong isotopic effects because the Ca diffusion is not strongly correlated with the movement of the framework atoms. In low-silica liquids, Ca diffusion is correlated with the movement of the other components and there is less mass discrimination. Combining our Ca results with Ca, Mg, and Li data from previous studies, we show that this model can explain most of the cation- and composition-dependence of diffusive isotopic fractionations observed thus far. A key parameter controlling isotopic discrimination is the ratio of the elemental (Ca, Mg, Li) diffusivity to the Eyring (or Si) diffusivity. However, all experiments done so far also exhibit isotopic features that are not yet fully explained; some of these may relate to small temperature gradients in the capsules, or to more complex coupling effects that are not captured in simplified diffusion models.

AB We present the elemental and isotopic composition of noble gases in the bulk solar wind collected by the NASA Genesis sample return mission. He, Ne, and Ar were analyzed in diamond-like carbon on a silicon substrate (DOS) and Kr-84,Kr-86 and Xe-129,Xe-132 in silicon targets by UV laser ablation noble gas mass spectrometry. Solar wind noble gases are quantitatively retained in DOS and with exception of He also in Si as shown by a stepwise heating experiment on a flown DOS target and analyses on other bulk solar wind collector materials. Solar wind data presented here are absolutely calibrated and the error of the standard gas composition is included in stated uncertainties. The isotopic composition of the light noble gases in the bulk solar wind is as follows: He-3/He-4: (4.64 +/- 0.09) x 10(-4), Ne-20/Ne-22: 13.78 +/- 0.03, Ne-21/Ne-22: 0.0329 +/- 0.0001, Ar-36/Ar-38 5.47 +/- 0.01. The elemental composition is: He-4/Ne-20: 656 +/- 5, and Ne-20/Ar-36 42.1 +/- 0.3. Genesis provided the first Kr and Xe data on the contemporary bulk solar wind. The preliminary isotope and elemental composition is: Kr-86/Kr-84: 0.302 +/- 0.003, Xe-129/Xe-132: 1.05 +/- 0.02, Ar-36/Kr-14 2390 +/- 150, and Kr-84/Xe-132 9.5 +/- 1.0. The He-3/He-4 and the He-4/Ne-20 ratios in the Genesis DOS target are the highest solar wind values measured in exposed natural and artificial targets. The isotopic composition of the other noble gases and the Kr/Xe ratio obtained in this work agree with data from lunar samples containing"young" (similar to 100 Ma) solar wind, indicating that solar wind composition has not changed within at least the last 100 Ma. Genesis could provide in many cases more precise data on solar wind composition than any previous experiment. Because of the controlled exposure conditions, Genesis data are also less prone to unrecognized systematic errors than, e.g., lunar sample analyses. The solar wind is the most authentic sample of the solar composition of noble gases, however, the derivation of solar noble gas abundances and isotopic composition using solar wind data requires a better understanding of fractionation processes acting upon solar wind formation.

TI Large-scale simulation of methane hydrate dissociation along the West
Spitsbergen Margin
SO GEOPHYSICAL RESEARCH LETTERS
LA English
DT Article
ID GAS-PRODUCTION; OCEAN
AB Vast quantities of methane are trapped in oceanic hydrate deposits, and there is concern that a rise in the ocean temperature will induce dissociation of these hydrate accumulations, potentially releasing large amounts of methane into the atmosphere. The recent discovery of active methane gas venting along the landward limit of the gas hydrate stability zone (GHSZ) on the shallow continental slope west of Spitsbergen could be an indication of this process, if the source of the methane can be confidently attributed to dissociating hydrates. In the first large-scale simulation study of its kind, we simulate shallow hydrate dissociation in conditions representative of the West Spitsbergen margin to test the hypothesis that the observed gas release originated from hydrates. The simulation results are consistent with this hypothesis, and are in remarkable agreement with the recently published observations. They show that shallow, low-saturation hydrate deposits, when subjected to temperature increases at the seafloor, can release significant quantities of methane, and that the releases will be localized near the landward limit of the top of the GHSZ. These results indicate the possibility that hydrate dissociation and methane release may be both a consequence and a cause of climate change. Citation: Reagan, M. T., and G. J.

AB Depth profiles of local volume expansions are precisely measured in 6H-SiC after irradiation at 150 K with 2 MeV Pt ions and following annealing at 770 K using transmission electron microscopy equipped with electron energy loss spectroscopy. It is found that the depth profile of local volume expansion from the as-implanted sample matches well with the depth profile of irradiation-induced local disorder measured by Rutherford backscattering spectrometry. Further, the local volume expansion increases linearly with local dose up to similar to 10%. By systematically comparing the depth profiles of local volume expansion and local relative disorder, it is revealed that the atomic volume of amorphous SiC continues to increase until it saturates at similar to 14% due to the increased chemical short-range disorder. This is believed to be one of the reasons for significant scatter in values of volume expansion previously reported for the irradiation-induced amorphous state of SiC.

AB As microsystems grow in their complexity, the number of material layers increases even as the thickness of these layers decreases. As a consequence, energetic transport through material intersections, the so-called thermal boundary conductance (TBC), becomes a greater contributor to the total thermal response of the system as a whole. Consequently, methods are sought that allow for insight into the mechanisms determining the efficiency of this transport, while simultaneously providing predictions with minimal computational investiture. In response, the current study extends the often employed diffuse mismatch model (DMM) to account for disorder that is frequently present in the materials making up the interface as well as the boundary itself. By applying assumptions regarding the scattering rates and mean free paths of phonons within a disordered solid, the resulting modifications of the spectral density of states induce changes in both the number and ratio of forward scattered phonons incident on a surface, and hence predictions of the TBC. Combining these assumptions with an accounting of the distance over which disorder persists, the newly implemented disorder DMM (delta-DMM) is shown to be more capable of predicting the TBC over a range of temperatures and material systems. Additionally, the model demonstrates that TBC is dependent on not only on the material properties but also on the morphology of these materials and the nature of their union.

AB A fluorescence-based digital image correlation (DIC) technique is used to characterize the in-plane strain development of blanket sol-gel derived lead zirconate titanate thin films deposited on platinized silicon substrates. The in-plane strain is also measured within film line features patterned via a mediated octadecyltrichlorosilane (ODS) monolayer. The results indicate that the selective film failure induced by the mediated ODS layer succeeds in slightly reducing the in-plane strain transverse to the line feature direction (similar to 25% lower), while remaining nearly the same as the blanket film case in the direction parallel to the line direction. Additional in-plane stress estimates from wafer curvature measurements for the two film configurations (blanket and ODS patterned) were consistent with the DIC measured strain results.

AB Photoemission experiments were performed on Si/MoSi2 multilayers using soft x-ray standing waves for excitation. The combination of photoemission spectroscopy and standing-wave excitation results in a depth profile of the sample that is also sensitive to chemical states. The experimental data were analyzed using an approximate analytical, rather than a full numerical, method in order to more quickly yield results, as well as to calibrate and better understand the method. The important parameters in the resulting equations are discussed in detail. Thus, we quickly obtain access to the key parameters modulating the photoelectron intensity excited by x-ray standing waves. We demonstrate the analytical approach on a simple experimental test data set.

AB The effects of oxidation time and annealing conditions on sputter-deposited magnetic tunnel junctions with a TiOx barrier have been investigated. High resolution electron microscopy showed that longer oxidation times led to a significant increase in barrier layer width and to the formation of large volumes of oxides of Co and Fe. Annealing promoted extensive diffusion of Mn to the barrier region and the oxidation of Mn to MnOx concurrent with the reduction in oxides of Co and Fe. Annealing also increased the peak oxygen content of the barrier region and resulted in a distinct asymmetry in the barrier oxide structure.

AB We investigate spall damage of single crystal Cu under supported (square) and decaying (Taylor wave) shock wave loading with molecular dynamics simulations. Varying the target-to-flyer plate thickness ratio R (with target thickness fixed) as well as the impact velocity induces square and Taylor waves with different pulse shapes, durations and strengths, which are well correlated with prespall damage, spall strength, and spall damage. Taylor wave loading results in higher spall strength than the supported shock loading at the same impact velocities, and the spall strength can be similar for both loadings with the same peak free surface velocities, while Taylor wave loading induces less spall damage than square wave loading. Void nucleation is preceded by plasticity and solid-state disordering. Multiple spall events appear to be independent of each other at the early stage of spallation. In applying the acoustic method for deducing the spall strength from the free surface velocity histories, one should consider the proper sound speed and R. The method works better for large R (Taylor waves) than for small R (square waves). However, this method may significantly underestimate strain rate for both types of loading.

AB Experiments have been carried out to investigate the alpha to omega phase transition in polycrystalline zirconium (Zr) metal. Samples with three levels of impurities were shock loaded using both gas-driven and powder-driven guns and ramp loaded using magnetic drive to investigate the effects of impurities on the properties of this solid-solid phase transition. Samples were backed by either sapphire or LiF windows and data were obtained using a VISAR to record the particle velocity at the sample/window interface. The results of these experiments showed significant differences in both the transition stress and kinetics for samples with different impurity levels demonstrating that impurities play an important role in the transformation mechanism in zirconium.

AB The nature of the lower crust across the southern African shield has been investigated by jointly inverting receiver functions and Rayleigh wave group velocities for 89 broadband seismic stations located in Botswana, South Africa and Zimbabwe. For large parts of both Archaean and Proterozoic terrains, the velocity models obtained from the inversions show shear wave velocities >= 4.0 km/s below similar to 20-30 km depth, indicating a predominantly mafic lower crust. However, for much of the Kimberley terrain and adjacent parts of the Kheis Province and Witwatersrand terrain in South Africa, as well as for the western part of the Tokwe terrain in Zimbabwe, shear wave velocities of <= 3.9 km/s are found below similar to 20-30 km depth, indicating an ntermediate-to-felsic lower crust. The areas of intermediate-to-felsic lower crust in South Africa coincide with regions where Ventersdorp rocks have been preserved, suggesting that the more evolved composition of the lower crust may have resulted from crustal reworking and extension during the Ventersdorp tectonomagmatic event at c. 2.7 Ga.

AB Surface forces play a paramount role in most aspects of Nanoimprint Lithography In particular, subjecting nanoimprinted patterns to moderate heating allows surface tension to smooth out undesirable roughness and defects in the patterns, but this "thermal reflow" treatment can induce structural decay or even collapse of the patterns by capillary instability if this process is not carefully controlled. Adhesion between the mold and polymer film can also cause the imprinted structure to tear or fracture. Fluorinated surfactants (FS) are attractive for reducing mold adhesion, yet the effects of these additives on nanostructure stability during thermal reflow are not well understood. Here we present thermal stability studies of linespace grating patterns created by Thermal Embossing Nanoimprint, Lithography (TENIL) on model polystyrene (PS) films with FS additives. As expected by energy considerations, FS segregates to the air interface, where it seems to facilitate mold release. This also reduces the surface energy and thus reduces the driving force for pattern "slumping" (height decay) However, the beneficial effects of the surfactant are counterbalanced by the fact that the FS decreases the effective film viscosity, which accelerates nanopattern leveling. The net effect is that the pattern height decay is strongly a function of FS concentration. This enhanced film fluidity in the presence of FS also makes the pattern more susceptible to an undulatory capillary instability under thermal reflow conditions. Surface phase segregation of FS and PS is also observed in conjunction with both slumping and lateral capillary instabilities, which may be useful for producing chemically patterned surfaces.

AB We apply neutron reflectivity to probe the internal structure of spin-assisted layer-by-layer (SA-LbL) Films composed of electrostatically assembled polyelectrolytes. We find that the level of stratification and the degree of layer intermixing call be controlled by varying the type and concentration of salt during SA-LbL assembly. We observe well-defined layer structure in SA-LbL films when deposited from salt-free solutions. These films feature 2-nm-thick bilayers, which are similar to 3-fold thicker than those in conventional LbL films assembled under similar conditions. The addition of a 10 mM phosphate buffer promotes progressive layer interdiffusion with increasing distance from the substrate. However, adding 0.1 M NaCl to the phosphate buffer solution restores the layer Stratification. We also find that SA-LbL films obtained from buffer solutions are more stratified as compared to the highly intermixed layers seen in conventional LbL films from buffer. Our results yield new insights into the mechanism of SA-LbL-assembly and the final microstructure in comparison with traditional LbL assemblies.

AB Most seafloor sediments are dated with radiocarbon, and the sediment is assumed to be zero-age (modern) when the signal of atmospheric testing of nuclear weapons is present (Fraction modern (Fm) > 1). Using a simple mass balance, we show that even with Fm > 1, half of the planktonic foraminifera at the seafloor can be centuries old, because of bioturbation. This calculation, and data from four core sites in the western North Atlantic indicate that, first, during some part of the Little Ice Age (LIA) there may have been more Antarctic Bottom Water than today in the deep western North Atlantic. Alternatively, bioturbation may have introduced much older benthic foraminifera into surface sediments. Second, paleo-based warming of Sargasso Sea surface waters since the LIA must lag the actual warming because of bioturbation of older and colder foraminifera.

AB The displacement of germanium (Ge) atoms induced by arsenic (As) ion implantation at room temperature was investigated using Ge isotope superlattices grown by molecular beam epitaxy. The depth profiles of (74)Ge isotopes in the (70)Ge/(nat)Ge isotope superlattices before and after ion implantation were obtained by secondary ion mass spectrometry. By representing the experimental data using a conventional integral model, Ge atomic displacement as a function of depth was obtained, from which we determined that 0.75 nm is the critical displacement necessary to make the structure appear amorphous under examination by cross-sectional transmission electron microscopy. However, we found that the amorphous Ge layers were recrystallized due to a local elevation of temperature caused by the implantation, which indicates that the samples should be cooled down during implantation to avoid the regrowth of amorphous Ge layers for this analysis.

A positive Seebeck coefficient is observed for Mg doped InN confirming p-type conductivity, though high doping and structural defect density can lead to n-type films. Transport measurements of undoped films are analyzed employing Rode's iterative Boltzmann equation method.

AB A novel system has been developed for the imaging of carrier transport within semiconductor nanostructures by operating a near field scanning optical microscopy (NSOM) within a scanning electron microscope. Luminescence associated with carrier recombination is collected with high spatial resolution to monitor the motion and recombination of charge generated by use of an electron beam as an independent point source. Light is collected in the near field from a scanning fiber using tuning fork feedback in an open architecture combined AFM/NSOM system allowing independent motion of sample and tip. From a single image, it is possible to obtain a direct measure of minority carrier diffusion length. This technique has been used in the near-field collection mode to image the diffusion of holes in n-type GaN-AlGaN core-shell nanowires, grown via Ni-catalyzed MOCVD. Measurements were made on tapered nanowires ranging in diameter from 500 to 800 nm, with lengths up to similar to 30 mu m. The average 1-dimensional carrier diffusion length was measured to be 1.2 +/- 0.2 mu m in the low injection limit. In addition, it is possible to map the luminescence that is waveguided to the end of the structure, imaging waveguide modes. Published by Elsevier B.V.

AB Electron paramagnetic resonance (EPR) and dynamic nuclear polarization (DNP) experiments with Li-doped FZ silicon wafers are reported. The Li related EPR spectrum of tetrahedral symmetry was detected clearly without external stress even at low temperatures (T < 5 K) implying that the Li electron spin-lattice relaxation time is much shorter than that of other shallow donors, e.g. phosphorus. The solid-effect was found to be responsible for the DNP and the polarization was enhanced by a factor of 87 at 3.2 K to reach 0.17%. (C) 2009 Elsevier B.V. All rights reserved.

AB In order to optimize the performance of molecular organic electronic devices it is important to study the intermolecular density of states and charge transport mechanisms in the environment of crystalline organic material. Using this approach in Field Effect Transistors (FETs) we show that material purification improves carrier mobility and decreases density of the deep localized electronic state. We also report a general exponential energy dependence of the density of localized states in a vicinity of the mobility edge (Fermi energies up to 7 times higher than the thermal energy (kT)) in a variety of the extensively purified molecular organic crystal FETs. This observation and the low activation energy of the order of kT suggest that molecular structural misplacements of the sizes that are comparable with thermal molecular modes rather than impurity deep traps play a role in formation of these shallow states. We find that the charge carrier mobility in the FET nanochannels, mu(eff), is parameterized by two factors, the free-carrier mobility, mu(0), and the ratio of the free carrier density to the total carrier density induced by gate bias. Crystalline FETs fabricated from rubrene, pentacene, and tetracene have a high free-carrier mobility, mu(0 similar to)50 cm(2)/Vs, at 300 K with lower device mu(eff) dominated by localized shallow gap states. This relationship suggests that further improvements in electronic performance could be possible with enhanced device quality. (C) 2009 Published by Elsevier B.V.

AB Single-and multiple-nanopore membranes are both highly interesting for biosensing and separation processes, as well as their ability to mimic biological membranes. The density of pores, their shape, and their surface chemistry are the key factors that determine membrane transport and separation capabilities. Here, we report silicon nitride (SiN) membranes with fully controlled porosity, pore geometry, and pore surface chemistry. An ultrathin freestanding SiN platform is described with conical or double-conical nanopores of diameters as small as several nanometers, prepared by the track-etching technique. This technique allows the membrane porosity to be tuned from one to billions of pores per square centimeter. We demonstrate the separation capabilities of these membranes by discrimination of dye and protein molecules based on their charge and size. This separation process is based on an electrostatic mechanism and operates in physiological electrolyte conditions. As we have also shown, the separation capabilities can be tuned by chemically modifying the pore walls. Compared with typical membranes with cylindrical pores, the conical and double-conical pores reported here allow for higher fluxes, a critical advantage in separation applications. In addition, the conical pore shape results in a shorter effective length, which gives advantages for single biomolecule detection applications such as nanopore-based DNA analysis.

AB Metallic nanoscale structures are capable of supporting surface plasmon polaritons (SPPs), propagating collective electron oscillations with tight spatial confinement at the metal surface. SPPs represent one of the most promising structures to beat the diffraction limit imposed by conventional dielectric optics. Ag nanowires have drawn increasing research attention due to 2D sub-100 nm mode confinement and lower losses as compared with fabricated metal structures. However, rational and versatile integration of Ag nanowires with other active and passive optical components, as well as Ag nanowire based optical routing networks, has yet to be achieved. Here, we demonstrate that SPPs can be excited simply by contacting a silver nanowire with a SnO(2) nanoribbon that serves both as an unpolarized light source and a dielectric waveguide. The efficient coupling makes it possible to measure the propagation-distance-dependent waveguide spectra and frequency-dependent propagation length on a single Ag nanowire. Furthermore, we have demonstrated prototypical photonic-plasmonic routing devices, which are essential for incorporating low-loss Ag nanowire waveguides as practical components into high-capacity photonic circuits.

AB Transmission of influenza viruses into the human population requires surmounting barriers to cross-species infection. Changes in the influenza polymerase overcome one such barrier. Viruses isolated from birds generally contain polymerases with the avian-signature glutamic acid at amino acid 627 in the PB2 subunit. These polymerases display restricted activity in human cells. An adaptive change in this residue from glutamic acid to the human-signature lysine confers high levels of polymerase activity in human cells. This mutation permits escape from a species-specific restriction factor that targets polymerases from avian viruses. A 2009 swine-origin H1N1 influenza A virus recently established a pandemic infection in humans, even though the virus encodes a PB2 with the restrictive glutamic acid at amino acid 627. We show here that the 2009 H1N1 virus has acquired second-site suppressor mutations in its PB2 polymerase subunit that convey enhanced polymerase activity in human cells. Introduction of this polymorphism into the PB2 subunit of a primary avian isolate also increased polymerase activity and viral replication in human and porcine cells. An alternate adaptive strategy has also been identified, whereby introduction of a human PA subunit into an avian polymerase overcomes restriction in human cells. These data reveal a strategy used by the 2009 H1N1 influenza A virus and identify other pathways by which avian and swine-origin viruses may evolve to enhance replication, and potentially pathogenesis, in humans.

AB We have measured W and Pt 4f(7/2) core-level photoemission spectra from interfaces formed by ultrathin Pt layers on W(1 1 0), completing our core-level measurements of W(1 1 0)-based bimetallic interfaces involving the group-10 metals Ni, Pd, and Pt. With increasing Pt coverage the sequence of W spectra can be described using three interfacial core-level peaks with binding-energy (BE) shifts (compared to the bulk) of -0.220 +/- 0.015, -0.060 +/- 0.015, and +0.110 +/- 0.010 eV. We assign these features to 1D, 2D pseudomorphic (ps), and 2D closed-packed (cp) Pt phases, respectively. For similar to 1 ps ML the Pt 4f(7/2) BE is 71.40 +/- 0.02 eV, a shift of +0.46 +/- 0.09 eV with respect to the BE of bulk Pt metal. The W 4f(7/2) core-level shifts induced by all three adsorbates are semiquantitatively described by the Born-Haber-cycle based partial-shift model of Nilsson et al. [39]. As with Ni/W(1 1 0), the difference in W 4f(7/2) binding energies between ps and cp Pt phases has a large structural contribution. The Pt 4f lineshape is consistent with a small density of states at the Fermi level, reflective of the Pt monolayer having noble-metal-like electronic structure. (C) 2009 Elsevier B.V.

The wetting behavior of the resulting films can be reversibly switched from hydrophobic to hydrophilic, through alternation of UV illumination and dark storage. The kinetics of this wetting transition are studied by monitoring the time evolution of the corresponding contact angles. Finally. the influence of the film properties over the observed wetting response is discussed. (C) 2009 Elsevier B.V. All rights reserved.

AB We observe kinetic features-velocity loops-at the alpha to epsilon phase transformation of iron, similar with the ones reported when water is frozen into its ice VII phase under comparable experimental conditions. By using a phase nucleation and growth kinetic model with pressure dependent phase interface velocity we find that the thermodynamic path followed by the sample is strongly dependent on the drive conditions and sample characteristics. The velocity loops become broader and shallower at slower compressions, while on faster time-scales, e.g., for laser drivers, the loops form at higher velocities and may eventually disappear.

AB In present work, the effects of hydrogen charging on Ln-based (Ln=La,Ce) bulk-metallic glasses (BMG) are studied. The (La(0.5)Ce(0.5))(65)Al(10)Co(25) were charged with hydrogen by an electrochemical method in an alkali solution. The hydrogen concentration in the sample after a 36 h charge can reach as high as 1286 w-ppm. With the presence of hydrogen atoms, the hardness of specimen increased by 80% compared to the as-cast samples. The structural evolution of the amorphous matrix due to the hydrogen-uptake process was investigated by the high-energy x-ray scattering technique. The sample surface was crystallized after hydrogen charging. X-ray diffraction measurements revealed broad crystalline peaks superimposed on an amorphous-scattering pattern. The crystalline phase grew from the surface to at least one hundred microns deep into the amorphous matrix. The atomic arrangements of both amorphous and crystalline phases were characterized by the atomic pair-distribution function.

AB Heteroepitaxial thin films of Mn-doped Ga2Se3 are grown by molecular beam epitaxy on Si(001):As. Mn-doped films are laminar for the first 1-2 nm, after which oriented islands with flat tops are observed by scanning tunneling microscopy. In contrast with the bulk phase diagram, which predicts MnGa2Se4 precipitates, the precipitates are identified by bond length measurements from extended x-ray absorption fine structure as rocksalt MnSe. This difference is attributed to superior lattice matching of MnSe to the substrate, and an epitaxial relationship between the MnSe and Si substrate is inferred.

AB We develop supercapacitor (SC) devices with large per-area capacitances by utilizing three-dimensional (3D) porous substrates. Carbon nanofibers (CNFs) functioning as active SC electrodes are grown on 3D nickel foam. The 3D porous substrates facilitate a mass loading of active electrodes and per-area capacitance as large as 60 mg/cm(2) and 1.2 F/cm(2), respectively. We optimize SC performance by developing an annealing-free CNF growth process that minimizes undesirable nickel carbide formation. Superior per-area capacitances described here suggest that 3D porous substrates are useful in various energy storage devices in which per-area performance is critical.

AB We have utilized the limited penetration depth of x-rays to study the near-surface properties of vertically aligned ZnO nanowires. For an energy of 600 eV the penetration depth varies between 3 and 132 nm as the incidence angle changes from 2 degrees to 33 degrees. Thus, by obtaining optical luminescence spectra as a function of incidence angle, it is possible to probe the near-surface region with nanometer-scale resolution. We will present angle dependent optical luminescence data from oriented ZnO nanowires. By fitting the results to a simple model, we extract a depth for the surface defect regions of similar to 14 nm.

AB We report the crystallization study of CoFeB/MgO/CoFeB magnetic tunnel junctions using in-situ, time-resolved synchrotron-based x-ray diffraction and transmission electron microscopy. It was found that the crystallization of amorphous CoFeB electrodes occurs on a time scale of seconds during the postgrowth high temperature annealing. The crystallization can be well fit by the Johnson-Mehl-Avrami model and the effective activation energy of the process was determined to be 150 kJ/mol. The solid-state epitaxy mode of CoFeB was found to involve separate crystallization at different locations followed by subsequent merging of small grains, instead of layer-by-layer growth of CoFeB film along the MgO template.

AB Optically detected magnetic resonance measurements are carried out to study formation of Ga interstitial-related defects in Ga(In)NAs alloys. The defects, which are among dominant nonradiative recombination centers that control carrier lifetime in Ga(In)NAs, are unambiguously proven to be common grown-in defects in these alloys independent of the employed growth methods. The defects formation is suggested to become thermodynamically favorable because of the presence of nitrogen, possibly due to local strain compensation.

AB Background: Polyamines regulate important cellular functions and polyamine dysregulation frequently occurs in cancer. The objective of this study was to use a systems approach to study the relative effects of PG-11047, a polyamine analogue, across breast cancer cells derived from different patients and to identify genetic markers associated with differential cytotoxicity.
Methods: A panel of 48 breast cell lines that mirror many transcriptional and genomic features present in primary human breast tumours were used to study the antiproliferative activity of PG-11047. Sensitive cell lines were further examined for cell cycle distribution and apoptotic response. Cell line responses, quantified by the GI(50) (dose required for 50% relative growth inhibition) were correlated with the omic profiles of the cell lines to identify markers that predict response and cellular functions associated with drug sensitivity.
Results: The concentrations of PG-11047 needed to inhibit growth of members of the panel of breast cell lines varied over a wide range, with basal-like cell lines being inhibited at lower concentrations than the luminal cell lines. Sensitive cell lines showed a significant decrease in S phase fraction at doses that produced little apoptosis. Correlation of the GI(50) values with the omic profiles of the cell lines identified genomic, transcriptional and proteomic variables associated with response.
Conclusions: A 13-gene transcriptional marker set was developed as a predictor of response to PG-11047 that warrants clinical evaluation. Analyses of the pathways, networks and genes associated with response to PG-11047 suggest that response may be influenced by interferon signalling and differential inhibition of aspects of motility and epithelial to mesenchymal transition.

TI Detecting coordinated regulation of multi-protein complexes using logic
analysis of gene expression

LA English
DT Article

CONTROL; RIBOSOME BIOGENESIS; YEAST; NETWORK; ORGANIZATION; CELL;
TRANSCRIPTION; COREGULATION
AB Background: Many of the functional units in cells are multi-protein complexes such as RNA polymerase, the ribosome, and the proteasome. For such units to work together, one might expect a high level of regulation to enable co-appearance or repression of sets of complexes at the required time. However, this type of coordinated regulation between whole complexes is difficult to detect by existing methods for analyzing mRNA co-expression. We propose a new methodology that is able to detect such higher order relationships.
Results: We detect coordinated regulation of multiple protein complexes using logic analysis of gene expression data. Specifically, we identify gene triplets composed of genes whose expression profiles are found to be related by various types of logic functions. In order to focus on complexes, we associate the members of a gene triplet with the distinct protein complexes to which they belong. In this way, we identify complexes related by specific kinds of regulatory relationships. For example, we may find that the transcription of complex C is increased only if the transcription of both complex A AND complex B is repressed. We identify hundreds of examples of coordinated regulation among complexes under various stress conditions. Many of these examples involve the ribosome. Some of our examples have been previously identified in the literature, while others are novel. One notable example is the relationship between the transcription of the ribosome, RNA polymerase and mannosyltransferase II, which is involved in N-linked glycan processing in the Golgi.
Conclusions: The analysis proposed here focuses on relationships among triplets of genes that are not evident when genes are examined in a pairwise fashion as in typical clustering methods. By grouping gene triplets, we are able to decipher coordinated regulation among sets of three complexes. Moreover, using all triplets that involve coordinated regulation with the ribosome, we derive a large network involving this essential cellular complex. In this network we find that all multi-protein complexes that belong to the same functional class are regulated in the same direction as a group (either induced or repressed).

AB Recently a number of nonnatural prenyl groups containing alkynes and azides have been developed as handles to perform click chemistry on proteins and peptides ending in the sequence "CAAX", where C is a cysteine that becomes alkylated, A is an aliphatic amino acid and X is any amino acid. When such molecules are modified, a tag containing a prenyl analogue and the "CAAX box" sequence remains. Here we report the synthesis of an alkyne-containing substrate comprised of only nine nonhydrogen atoms. This substrate was synthesized in six steps from 3-methylbut-2-en-1-ol and has been enzymatically incorporated into both proteins and peptides by using protein farnesyltransferase. After prenylation the final three amino acids required for enzymatic recognition can be removed by using carboxypeptidase Y, leaving a single residue (the cysteine from the "CAAX box") and the prenyl analogue as the only modifications. We also demonstrate that this small tag minimizes the impact of the modification on the solubility of the targeted protein. Hence, this new approach should be useful for applications in which the presence of a large tag hinders the modified protein's solubility, reactivity, or utility.

AB Quantum chemistry-based dipole polarizable and nonpolarizable force fields have been developed for 1,3,5-triamino-2,4,6-trinitrobenzene (TATB). Molecular dynamics simulations of TATB crystals were performed for hydrostatic pressures up to 10 GPa at 300 K and for temperatures between 200 and 400 K at atmospheric pressure. The predicted heat of sublimation and room-temperature volumetric hydrostatic compression curve were found to be in good agreement with available experimental data. The hydrostatic compression curves for individual unit cell parameters were found to be in reasonable agreement with those data. The pressure- and temperature-dependent second-order isothermal elastic tensor was determined for temperatures between 200 and 400 K at normal pressure and for pressures up to 10 GPa on the 300 K isotherm. Simulations indicate considerable anisotropy in the mechanical response, with modest softening and significant stiffening of the crystal with increased temperature and pressure, respectively. For most properties the polarizable potential was found to yield better agreement with available experimental properties.

AB High pressure Raman spectroscopy of NH3BH3-H-2 mixtures up to 60 GPa reveals unusual pressure-induced complexation and intermolecular interactions. Stretching modes of H-2 in the complex arise at 6.7 and 10 GPa, increasing in frequency with pressure of up to 60 GPa with different pressure coefficients, and at similar to 40 GPa, the lower frequency mode approaches vibron frequency of bulk H-2. Pressure-induced transformations in pure NH3BH3 studied up to 60 GPa reveal a disorder-order transition at 1 GPa (phase II) and further transitions at 5 (phase III) and 10 GPa (phase IV). The spectra of both pure NH3BH3 and the NH3BH3-H-2 complex provide evidence for strengthened of the N-H delta+center dot H delta--B dihydrogen bonding linkages up to 50 GPa, beyond which they weaken. The dihydrogen bonding breaks down due to interactions with H-2 between 15 and 20 GPa in the NH3BH3-H-2 complex. The behavior of the nu(NH3) modes in the NH3BH3-H-2 complex indicates a dominant role of the NH3 functional group in the observed interactions.

AB A study of the structural relaxation of nitromethane subsequent to shock loading normal to the (100) crystal plane performed using molecular dynamics and a nonreactive potential was reported recently [J. Chem. Phys. 131, 064503 (2009)]. Starting from initial temperatures of T(0)=50 and 200 K, shocks were simulated using impact velocities U(p) ranging from 0.5 to 3.0 km s(-1); clear evidence of melting was obtained for shocks initiated with impacts of 2.0 km s(-1) and higher. Here, we report the results of analyses of those simulation data using a method based on the Eckart frame normal-mode analysis that allows partitioning of the kinetic energy among the molecular degrees of freedom. A description of the energy transfer is obtained in terms of average translational and rotational kinetic energies in addition to the rates of individual vibrational mode heating. Generally, at early times postshock a large superheating of the translational and rotational degrees of freedom (corresponding to phonon modes of the crystal) is observed. The lowest frequency vibrations (gateway modes) are rapidly excited and also exhibit superheating. Excitation of the remaining vibrational modes occurs more slowly. A rapid, early excitation of the symmetric C-H stretch mode was observed for the shock conditions T(0)=50 K and U(p)=2.0 km s(-1) due to a combination of favorable alignment of molecular orientation with the shock direction and frequency matching between the vibration and shock velocity.

AB We report the results of numerical simulations of random, three-dimensional, periodic, tetrafunctional networks in response to a volume-preserving tensile strain. For the intranode force, we use a polynomial fit to a purely enthalpic ab initio force extension curve for extended polyisoprene. The simulation includes a relaxation procedure to minimize the node forces and enforces chain rupture when the extension of a network chain reaches the ab initio rupture strain. For the reasonable assumption that the distribution of network chain lengths is Gaussian, we find that the calculated snap-back velocity, temperature increase due to chain ruptures and predicted tensile stress versus strain curve are consistent with experimental data in the moderate to high extension regime. Our results show that a perfect tetrafunctional polyisoprene network is extremely robust, capable of supporting tensile stresses at least a factor of 10 greater than what is observed experimentally.

AB New infrared absorbing species are identified in the pulse radiolysis of supercritical Kr at high pressures. The species are believed to be excimers. Their formation and decay rates have been time resolved using the Laser Electron Accelerator Facility. An initial species, formed in less than 1 ns, absorbs at several wavelengths between 790 and 1300 nm; The decay of this species is initially fast, followed by a slower component; the decay rate increases with pressure. As this initial species decays a second excimer is formed absorbing at 830, 890, and 990 nm. The growth and decay rates of this excimer are also pressure dependent. A third excimer, absorbing between 1000 and 1200 nm grows at a rate similar to that of the decay of the second species. The decay rate of the third species is also pressure dependent; the lifetime increases from 9.4 ns at 109 bar to 49 ns at 15 bar. A kinetic mechanism is proposed that satisfactorily reproduces the experimental results. The first species is identified as a higher energy gerade triplet state excimer and the second as the singlet gerade state.

AB Initial value representations (IVRs) of semiclassical (SC) theory provide a general approach for adding quantum mechanical effects to classical molecular dynamics simulations of large molecular systems. Of the various versions of SC-IVR methodology for evaluating time correlation functions, the Fourier transform forward-backward (FB) approach is the simplest one that is able to describe true quantum coherence effects, so it is of considerable importance to find efficient and systematic ways for implementing it. It is shown in this paper that a Gaussian approximation for the "structure function"-the dependence of the correlation function on the (typically) momentum jump parameter-provides an efficient and accurate way for doing so. The approach is illustrated by an application to the time-dependent radial distribution function of I-2 (after photoexcitation) in a cluster of (up to 16) argon atoms.

AB Absolute cross sections for the K-shell photoionization of ground-state Li-like carbon [C3+(1s(2)2s(2)S)] ions were measured by employing the ion-photon merged-beams technique at the Advanced Light Source. The energy ranges 299.8-300.15 eV, 303.29-303.58 eV and 335.61-337.57 eV of the [1s(2s2p)P-3]P-2, [1s(2s2p)P-1]P-2 and [(1s2s)S-3 3p]P-2 resonances, respectively, were investigated using resolving powers of up to 6000. The autoionization linewidth of the [1s(2s2p)P-1]P-2 resonance was measured to be 27 +/- 5meV and compares favourably with a theoretical result of 26 meV obtained from the intermediate coupling R-matrix method. The present photoionization cross section results are compared with the outcome from photorecombination measurements by employing the principle of detailed balance.

TI Nanoscale Imaging of Whole Cells Using a Liquid Enclosure and a Scanning
Transmission Electron Microscope
SO PLOS ONE

DT Article
ID TOMOGRAPHY; INTERFACE; GROWTH; STEM
AB Nanoscale imaging techniques are needed to investigate cellular function at the level of individual proteins and to study the interaction of nanomaterials with biological systems. We imaged whole fixed cells in liquid state with a scanning transmission electron microscope (STEM) using a micrometer-sized liquid enclosure with electron transparent windows providing a wet specimen environment. Wet-STEM images were obtained of fixed E. coli bacteria labeled with gold nanoparticles attached to surface membrane proteins. Mammalian cells (COS7) were incubated with gold-tagged epidermal growth factor and fixed. STEM imaging of these cells resulted in a resolution of 3 nm for the gold nanoparticles. The wet-STEM method has several advantages over conventional imaging techniques. Most important is the capability to image whole fixed cells in a wet environment with nanometer resolution, which can be used, e. g., to map individual protein distributions in/on whole cells. The sample preparation is compatible with that used for fluorescent microscopy on fixed cells for experiments involving nanoparticles. Thirdly, the system is rather simple and involves only minimal new equipment in an electron microscopy (EM) laboratory.

AB Although the biochemical correlates of freeze tolerance in insects are becoming well-known, the process of ice formation in vivo is subject to speculation. We used synchrotron x-rays to directly visualise real-time ice formation at 3.3 Hz in intact insects. We observed freezing in diapausing 3(rd) instar larvae of Chymomyza amoena (Diptera: Drosophilidae), which survive freezing if it occurs above -14 degrees C, and non-diapausing 3(rd) instar larvae of C. amoena and Drosophila melanogaster (Diptera: Drosophilidae), neither of which survive freezing. Freezing was readily observed in all larvae, and on one occasion the gut was seen to freeze separately from the haemocoel. There were no apparent qualitative differences in ice formation between freeze tolerant and non-freeze tolerant larvae. The time to complete freezing was positively related to temperature of nucleation (supercooling point, SCP), and SCP declined with decreasing body size, although this relationship was less strong in diapausing C. amoena. Nucleation generally occurred at a contact point with the thermocouple or chamber wall in non-diapausing larvae, but at random in diapausing larvae, suggesting that the latter have some control over ice nucleation. There were no apparent differences between freeze tolerant and non-freeze tolerant larvae in tracheal displacement or distension of the body during freezing, although there was markedly more distension in D. melanogaster than in C. amoena regardless of diapause state. We conclude that although control of ice nucleation appears to be important in freeze tolerant individuals, the physical ice formation process itself does not differ among larvae that can and cannot survive freezing. This suggests that a focus on cellular and biochemical mechanisms is appropriate and may reveal the primary adaptations allowing freeze tolerance in insects.

AB Nitrogen-containing carbon nanotube cups are crosslinked with glutaraldehyde to form capsule-shaped nanostructures. Introduction of commercially available gold nanoparticles prior to the cross-linkage process results in their encapsulation within the interior cavity of the linked structures (see image). A similar encapsulation of ZnS:Tb nanoparticles shows the general applicability of the system. Such a facile protocol alludes to drug-delivery and energy-storage applications.

ID VELOCITY; GLASS; SIO2
AB Although refraction of light at grain boundaries can significantly alter Brillouin spectra-hence inferred acoustic velocities-of powder samples, we demonstrate that the effects of (multiple) elastic scattering can be eliminated through 1) use of refractive index-matching oils or 2) application of high pressures (>= 1 GPa). In this manner, we determine the acoustic-wave velocities of soda-lime glass powder to pressures of 13 GPa, finding good agreement with previous measurements on bulk samples. Our results provide a baseline for reliable acoustic-wave velocity measurements at high pressures via Brillouin spectroscopy on polycrystalline samples. Citation: Gleason, A. E., B. Chen, and R.

AB Antecedents of Escherichia coli B have been traced through publications, inferences, and personal communication to a strain from the Institut Pasteur in Paris used by d'Herelle in his studies of bacteriophages as early as 1918 (a strain not in the current collection). This strain appears to have passed from d'Herelle to Bordet in 1920, and from Bordet to at least three other laboratories by 1925. The strain that Gratia received from Bordet was apparently passed to Bronfenbrenner by 1924 and from him to Luria around 1941. Delbruck and Luria published the first paper calling this strain B in 1942. Its choice as the common host for phages T1-T7 by the phage group that developed around Delbruck, Luria, and Hershey in the 1940s led to widespread use of B along with E. coli K-12, chosen about the same time for biochemical and genetic studies by Tatum and Lederberg. Not an currently available strains related to B are descended from the B of Delbrilck and Luria; at least three strains with somewhat different characteristics were derived independently by Hershey directly from the Bronfenbrenner strain, and a strain that appears to have passed from Bordet to Wollman is in the current Collection of the Institut Pasteur. The succession of manipulations and strains that led from the B of Delbruck and Luria to REL606 and BL21 (DE3) is given, established in part through evidence from their recently determined complete genome sequences.

AB Escherichia coli K-12 and B have been the subjects of classical experiments from which much of our understanding of molecular genetics has emerged. We present here complete genome sequences of two E. coli B strains, REL606, used in a long-term evolution experiment, and BL21(DE3), widely used to express recombinant proteins. The two genomes differ in length by 72,304 bp and have 426 single base pair differences, a seemingly large difference for laboratory strains having a common ancestor within the last 67 years. Transpositions by IS1 and IS150 have occurred in both lineages. Integration of the DE3 prophage in BL21(DE3) apparently displaced a defective prophage in the lambda attachment site of B. As might have been anticipated from the many genetic and biochemical experiments comparing B and K-12 over the years, the B genomes are similar in size and organization to the genome of E. coli K-12 MG1655 and have similar to 99% sequence identity over similar to 92% of their genomes. E. coli B and K-12 differ considerably in distribution of IS elements and in location and composition of larger mobile elements. An unexpected difference is the absence of a large cluster of flagella genes in B, due to a 41 kbp IS1-mediated deletion. Gene clusters that specify the LPS core, 0 antigen, and restriction enzymes differ substantially, presumably because of horizontal transfer. Comparative analysis of 32 independently isolated E. coli and Shigella genomes, both commensals and pathogenic strains, identifies a minimal set of genes in common plus many strain-specific genes that constitute a large E. coli pan-genome.

AB Each difference between the genome sequences of Escherichia coli B strains REL606 and BL21(DE3) can be interpreted in light of known laboratory manipulations plus a gene conversion between ribosomal RNA operons. Two treatments with 1-methyl-3-nitro-1-nitrosoguanidine in the REL606 lineage produced at least 93 single-base-pair mutations (similar to 90% GC-to-AT transitons) and 3 single-base-pair GC deletions. Two UV treatments in the BL21(DE3) lineage produced only 4 single-base-pair mutations but 16 large deletions. P1 transductions from K-12 into the two B lineages produced 317 single-base-pair differences and 9 insertions or deletions, reflecting differences between B DNA in BL21(DE3) and integrated restriction fragments of K-12 DNA inherited by REL606. Two sites showed selective enrichment of spontaneous mutations. No unselected spontaneous single-base-pair mutations were evident. The genome sequences revealed that a progenitor of REL606 had been misidentified, explaining initially perplexing differences. Limited sequencing of other B strains defined characteristic properties of B and allowed assembly of the inferred genome of the ancestral B of Delbruck and Luria. Comparison of the B and K-12 genomes shows that more than half of the 3793 proteins of their basic genomes are predicted to be identical, although similar to 310 appear to be functional in either B or K-12 but not in both. The ancestral basic genome appears to have had similar to 4039 coding sequences occupying similar to 4.0 Mbp. Repeated horizontal transfer from diverged Escherichia coli genomes and homologous recombination may explain the observed variable distribution of single-base-pair differences. Fifteen sites are occupied by phage-related elements, but only six by comparable elements at the same site. More than 50 sites are occupied by IS elements in both B and K, 16 in common, and likely founding IS elements are identified. A signature of widespread cryptic phage P4-type mobile elements was identified. Complex deletions (dense clusters of small deletions and substitutions) apparently removed nonessential genes from similar to 30 sites in the basic genomes. (C) 2009 Elsevier Ltd.

AB The development of radiation hydrodynamical methods that are able to follow gas dynamics and radiative transfer (RT) self-consistently is key to the solution of many problems in numerical astrophysics. Such fluid flows are highly complex, rarely allowing even for approximate analytical solutions against which numerical codes can be tested. An alternative validation procedure is to compare different methods against each other on common problems, in order to assess the robustness of the results and establish a range of validity for the methods. Previously, we presented such a comparison for a set of pure RT tests (i.e. for fixed, non-evolving density fields). This is the second paper of the Cosmological Radiative Transfer Comparison Project, in which we compare nine independent RT codes directly coupled to gas dynamics on three relatively simple astrophysical hydrodynamics problems: (i) the expansion of an H ii region in a uniform medium, (ii) an ionization front in a 1/r2 density profile with a flat core and (iii) the photoevaporation of a uniform dense clump. Results show a broad agreement between the different methods and no big failures, indicating that the participating codes have reached a certain level of maturity and reliability. However, many details still do differ, and virtually every code has showed some shortcomings and has disagreed, in one respect or another, with the majority of the results. This underscores the fact that no method is universal and all require careful testing of the particular features which are most relevant to the specific problem at hand.

AB We develop a theory of far from the equilibrium transport in arrays of tunnel junctions. We find that if the rate of the electron-electron interactions exceeds the rate of the electron-phonon energy exchange, the energy relaxation ensuring the charge transfer may occur sequentially. In particular, cotunneling transport in arrays of junctions is dominated by the relaxation via the intermediate bosonic environment, the electron-hole excitations, rather than by the electron-phonon mechanism. The current-voltage characteristics are highly sensitive to the spectrum of the environmental modes and to the applied bias, which sets the lower bound for the effective temperature. We demonstrate that the energy gap in the electron-hole spectrum which opens below some critical temperature T(*) due to long-range Coulomb interactions gives rise to the suppression of the tunneling current.

ID PLASMA INTERACTIONS; SOLID TARGETS
AB We present experimental studies on ion acceleration from ultrathin diamondlike carbon foils irradiated by ultrahigh contrast laser pulses of energy 0.7 J focused to peak intensities of 5x10(19) W/cm(2). A reduction in electron heating is observed when the laser polarization is changed from linear to circular, leading to a pronounced peak in the fully ionized carbon spectrum at the optimum foil thickness of 5.3 nm. Two-dimensional particle-in-cell simulations reveal that those C(6+) ions are for the first time dominantly accelerated in a phase-stable way by the laser radiation pressure.

AB We present the first ultrafast temporally, spectrally, and angularly resolved x-ray scattering measurements from shock-compressed matter. The experimental spectra yield the absolute elastic and inelastic scattering intensities from the measured density of free electrons. Laser-compressed lithium-hydride samples are well characterized by inelastic Compton and plasmon scattering of a K-alpha x-ray probe providing independent measurements of temperature and density. The data show excellent agreement with the total intensity and structure when using the two-species form factor and accounting for the screening of ion-ion interactions.

AB The permeation of rare-gas atoms through deeply supercooled metastable liquid methanol films is used to probe the diffusivity. The technique allows for measurement of supercooled liquid mobility at temperatures near the glass transition. The temperature dependence of the diffusivity is well described by a Vogel-Fulcher-Tamman equation. These new measurements and the temperature dependent kinetic parameters obtained from their analysis provide clear evidence that methanol is a fragile liquid near the glass transition.

AB We report a single rectifying conically shaped nanopore system with ion current fluctuations whose 1/f noise characteristics observed at low frequencies are voltage dependent. Switching the voltage polarity allows one to switch between a system that produces equilibrium and nonequilibrium 1/f ion current fluctuations. The nonequilibrium fluctuations in the high-conductance state of the device are characterized by exponential dependence of the normalized power spectrum on voltage. The asymmetric 1/f noise is found characteristic for rectifying polymer nanopores and absent in pores with Ohmic current-voltage curves.

AB The effects of fluctuating initial conditions are studied in the context of relativistic heavy ion collisions where a rapidly evolving system is formed. Two-particle correlation analysis is applied to events generated with the NEXSPHERIO hydrodynamic code, starting with fluctuating nonsmooth initial conditions (IC). The results show that the nonsmoothness in the IC survives the hydroevolution and can be seen as topological features of the angular correlation function of the particles emerging from the evolving system. A long range correlation is observed in the longitudinal direction and in the azimuthal direction a double peak structure is observed in the opposite direction to the trigger particle. This analysis provides clear evidence that these are signatures of the combined effect of tubular structures present in the IC and the proceeding collective dynamics of the hot and dense medium.

TI Diffractive Imaging Using Partially Coherent X Rays
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID PHASE RETRIEVAL; MICROSCOPY
AB The measured spatial coherence characteristics of the illumination used in a diffractive imaging experiment are incorporated in an algorithm that reconstructs the complex transmission function of an object from experimental x-ray diffraction data using 1.4 keV x rays. Conventional coherent diffractive imaging, which assumes full spatial coherence, is a limiting case of our approach. Even in cases in which the deviation from full spatial coherence is small, we demonstrate a significant improvement in the quality of wave field reconstructions. Our formulation is applicable to x-ray and electron diffraction imaging techniques provided that the spatial coherence properties of the illumination are known or can be measured.

TI Suppression of Proximity Effect and the Enhancement of p-Wave
Superconductivity in the Sr2RuO4-Ru System
SO PHYSICAL REVIEW LETTERS

DT Article
ID UNCONVENTIONAL SUPERCONDUCTORS; PHENOMENOLOGICAL THEORY; INTERFACES;
TRANSITION; JUNCTIONS; PHASE
AB We report unexpected phenomena observed on the Sr2RuO4-Ru eutectic phase featuring Ru islands embedded in a bulk crystal of the chiral p-wave superconductor Sr2RuO4. It was found that the Sr2RuO4/Ru interface is atomically sharp, terminated uniformly by a Sr/O layer. Surprisingly, the proximity-induced p-wave superconducting energy gap predicted by theory was not detected inside Ru islands. Our results suggest that the previously observed enhancement of superconductivity in this eutectic phase occurs away from rather than near the Sr2RuO4/Ru interface, where dislocations and phonon hardening were found.

MANIPULATION; STATES; DOT
AB Two-level systems are at the core of numerous real-world technologies such as magnetic resonance imaging and atomic clocks. Coherent control of the state is achieved with an oscillating field that drives dynamics at a rate determined by its amplitude. As the strength of the field is increased, a different regime emerges where linear scaling of the manipulation rate breaks down and complex dynamics are expected. By calibrating the spin rotation with an adiabatic passage, we have measured the room-temperature "strong-driving" dynamics of a single nitrogen vacancy center in diamond. With an adiabatic passage to calibrate the spin rotation, we observed dynamics on sub-nanosecond time scales. Contrary to conventional thinking, this breakdown of the rotating wave approximation provides opportunities for time-optimal quantum control of a single spin.

AB Organic aerosol (OA) particles affect climate forcing and human health, but their sources and evolution remain poorly characterized. We present a unifying model framework describing the atmospheric evolution of OA that is constrained by high-time-resolution measurements of its composition, volatility, and oxidation state. OA and OA precursor gases evolve by becoming increasingly oxidized, less volatile, and more hygroscopic, leading to the formation of oxygenated organic aerosol (OOA), with concentrations comparable to those of sulfate aerosol throughout the Northern Hemisphere. Our model framework captures the dynamic aging behavior observed in both the atmosphere and laboratory: It can serve as a basis for improving parameterizations in regional and global models.

AB Astronomers have proposed a number of mechanisms to produce supernova explosions. Although many of these mechanisms are now not considered primary engines behind supernovae (SNe), they do produce transients that will be observed by upcoming ground-based surveys and NASA satellites. Here, we present the first radiation-hydrodynamics calculations of the spectra and light curves from three of these "failed" SNe: SNe with considerable fallback, accretion-induced collapse of white dwarfs, and energetic helium flashes (also known as type Ia SNe).

AB The Fermi Gamma-ray Space Telescope has opened a new high-energy window in the study of gamma-ray bursts (GRBs). Here we present a thorough analysis of GRB 080825C, which triggered the Fermi Gamma-ray Burst Monitor (GBM), and was the first firm detection of a GRB by the Fermi Large Area Telescope (LAT). We discuss the LAT event selections, background estimation, significance calculations, and localization for Fermi GRBs in general and GRB 080825C in particular. We show the results of temporal and time-resolved spectral analysis of the GBM and LAT data. We also present some theoretical interpretation of GRB 080825C observations as well as some common features observed in other LAT GRBs.

AB We report results from an intensive multiwavelength campaign on the intermediate-frequency-peaked BL Lacertae object W Com (z = 0.102) during a strong outburst of very high energy gamma-ray emission in 2008 June. The very high energy gamma-ray signal was detected by VERITAS on 2008 June 7-8 with a flux F(>200 GeV) = (5.7 +/- 0.6) x 10(-11) cm(-2) s(-1), about three times brighter than during the discovery of gamma-ray emission from W Com by VERITAS in 2008 March. The initial detection of this flare by VERITAS at energies above 200 GeV was followed by observations in high-energy gamma rays (AGILE; E-gamma >= 100 MeV), X-rays (Swift and XMM-Newton), and at UV, and ground-based optical and radio monitoring through the GASP-WEBT consortium and other observatories. Here we describe the multiwavelength data and derive the spectral energy distribution of the source from contemporaneous data taken throughout the flare.

AB We report the discovery of four very bright, strongly lensed galaxies found via systematic searches for arcs in Sloan Digital Sky Survey Data Release 5 and 6. These were followed up with spectroscopy and imaging data from the Astrophysical Research Consortium 3.5 m telescope at Apache Point Observatory and found to have redshift z > 2.0. With isophotal magnitudes r = 19.2-20.4 and 3 '' diameter magnitudes r = 20.0-20.6, these systems are some of the brightest and highest surface brightness lensed galaxies known in this redshift range. In addition to the magnitudes and redshifts, we present estimates of the Einstein radii, which range from 5 ''.0 to 12 ''.7, and use those to derive the enclosed masses of the lensing galaxies.

AB We determine photometric metal abundance estimates for individual main-sequence stars in the Virgo Overdensity (VOD), which covers almost 1000 deg(2) on the sky, based on a calibration of the metallicity sensitivity of stellar isochrones in the gri filter passbands using field stars with well-determined spectroscopic metal abundances. Despite the low precision of the method for individual stars, we derive [Fe/H] = -2.0 +/- 0.1 (internal) +/- 0.5 (systematic) for the metal abundance of the VOD from photometric measurements of 0.7 million stars in the northern Galactic hemisphere with heliocentric distances from similar to 10 kpc to similar to 20 kpc. The metallicity of the VOD is indistinguishable, within Delta[Fe/H] <= 0.2, from that of field halo stars covering the same distance range. This initial application suggests that the Sloan Digital Sky Survey gri passbands can be used to probe the properties of main-sequence stars beyond similar to 10 kpc, complementing studies of nearby stars from more metallicity-sensitive color indices that involve the u passband.

AB We report the discovery of a multiply lensed Ly alpha emitter at z = 3.90 behind the massive cluster WARPS J1415.1+3612 at z = 1.026. Images taken by the Hubble Space Telescope using the Advanced Camera for Surveys reveal a complex lensing system that produces a prominent, highly magnified arc and a triplet of smaller arcs grouped tightly around a spectroscopically confirmed cluster member. Spectroscopic observations using the Faint Object Camera and Spectrograph on Subaru confirm strong Lya emission in the source galaxy and provide the redshifts for more than 21 cluster members with a velocity dispersion of 807 +/- 185 km s(-1). Assuming a singular isothermal sphere profile, the mass within the Einstein ring (7.13 +/- 0.'' 38) corresponds to a central velocity dispersion of 686(-19)(+15) km s(-1) for the cluster, consistent with the value estimated from cluster member redshifts. Our mass profile estimate from combining strong lensing and dynamical analyses is in good agreement with both X-ray and weak lensing results.

AB Combining results from several techniques of attosecond spectroscopy, we show that ionization gating of high-harmonic emission on the leading edge of the driving pulse produces isolated attosecond pulses with a contrast ratio (the energy in the main pulse normalized to the energy in adjacent satellite pulses) c = 3.3 +/- 0: 2. Half-cycle cutoff analysis confirms that harmonic generation proceeds in the ionization-gated regime. The attosecond pulse contrast is measured using the technique of carrier-envelope phase (CEP)-scanning, recently developed by our group, in which photoelectrons generated from Ne atoms by the harmonic pulse are streaked as a function of CEP. Streaking of photoelectrons as a function of attosecond time delay also confirms the isolated nature of the harmonic pulse, which is measured to have a duration of 430 +/- 15 as, limited by the bandwidth of the reflective X-ray optics employed. The combined measurements imply that the experimental advantages of the ionization gating technique-tunable X-ray emission, relaxed sensitivity to the CEP and scalability to longer driver pulses-are also conferred on isolated attosecond pulse production.

AB We describe the implementation of a short-range parallel molecular dynamics (MD) code, SPaSM, on the heterogeneous general-purpose Roadrunner supercomputer. Each Roadrunner 'TriBlade' compute node consists of two AMD Opteron dual-core microprocessors and four IBM PowerXCell 8i enhanced Cell microprocessors (each consisting of one PPU and eight SPU cores), so that there are four MPI ranks per node, each with one Opteron and one Cell. We will briefly describe the Roadrunner architecture and some of the initial hybrid programming approaches that have been taken, focusing on the SPaSM application as a case study. An initial 'evolutionary' port, in which the existing legacy code runs with minor modifications on the Opterons and the Cells are only used to compute interatomic forces, achieves roughly a 2x speedup over the unaccelerated code. On the other hand, our 'revolutionary' implementation adopts a Cell-centric view, with data structures optimized for, and living on, the Cells. The Opterons are mainly used to direct inter-rank communication and perform I/O-heavy periodic analysis, visualization, and checkpointing tasks. The performance measured for our initial implementation of a standard Lennard-Jones pair potential benchmark reached a peak of 369 Tflop/s double-precision floating-point performance on the full Roadrunner system (27.7% of peak), nearly 10 x faster than the unaccelerated (Opteron-only) version.

AB We report initial experience with gas dynamics simulation on the Los Alamos Roadrunner machine. In this initial work, we have restricted our attention to flows in which the flow Mach number is less than 2. This permits us to use a simplified version of the PPM gas dynamics algorithm that has been described in detail by Woodward (2006). We follow a multifluid volume fraction using the PPB moment-conserving advection scheme, enforcing both pressure and temperature equilibrium between two monatomic ideal gases within each grid cell. The resulting gas dynamics code has been extensively restructured for efficient multicore processing and implemented for scalable parallel execution on the Roadrunner system. The code restructuring and parallel implementation are described and performance results are discussed. For a modest grid size, sustained performance of 3.89 Gflop s(-1) CPU-core(-1) is delivered by this code on 36 Cell processors in 9 triblade nodes of a single rack of Roadrunner hardware.

AB The call for ever-increasing model resolutions and physical processes in climate and weather models demands a continual increase in computing power. The IBM Cell processor's order-of-magnitude peak performance increase over conventional processors makes it very attractive to fulfill this requirement However, the Cell's characteristics, 256kB local memory per SPE and the new low-level communication mechanism, make it very challenging to port an application. As a trial, we selected the solar radiation component of the NASA GEOS-5 climate model, which: (1) is representative of column-physics components (half of the total computational time), (2) has an extremely high computational intensity: the ratio of computational load to main memory transfers, and (3) exhibits embarrassingly parallel column computations. In this paper, we converted the baseline code (single-precision Fortran) to C and ported it to an IBM BladeCenter QS20. For performance, we manually SIMDize four independent columns and include several unrolling optimizations. Our results show that when compared with the baseline implementation running on one core of Intel's Xeon Woodcrest, Dempsey, and Itanium2, the Cell is approximately 8.8x, 11.6x, and 12.8x faster, respectively. Our preliminary analysis shows that the Cell can also accelerate the dynamics component (similar to 25% total computational time). We believe these dramatic performance improvements make the Cell processor very competitive as an accelerator. Copyright (C) 2009 John Wiley & Sons, Ltd.

AB The kinetics for the selective hydrogenation of acetylene-ethylene mixtures over model Pd(1 1 1) and bimetallic Pd-Ag alloy surfaces were examined using first principles-based kinetic Monte Carlo (KMC) simulations to elucidate the effects of alloying and reaction conditions. The elementary steps that control the selective and unselective pathways, including hydrogenation, dehydrogenation, and C-C bond breaking, were analyzed using first-principle density functional theory (DFT) calculations. The results were used to construct an intrinsic kinetic database that was used in a variable time step kinetic Monte Carlo simulation to follow the kinetics and the molecular transformations in the selective hydrogenation of acetylene-ethylene feeds over Pd and Pd-Ag surfaces. Through-surface and through-space lateral interactions between coadsorbates were estimated using DFT-parameterized bond order conservation and van der Waal interaction models, respectively. The simulations show that the rate of acetylene hydrogenation as well as ethylene selectivity increases with temperature over both the Pd(1 1 1) and the Pd-Ag/Pd(1 1 1) alloy surfaces. The selective hydrogenation of acetylene to ethylene proceeds via the formation of a surface vinyl intermediate. The unselective formation of ethane is the result of the over-hydrogenation of ethylene as well as over-hydrogenation of vinyl to form ethylidene. Ethylidene further hydrogenates to form ethane and dehydrogenates to form ethylidyne. While ethylidyne is not reactive, it can block adsorption sites and thus limit the availability of hydrogen on the surface which enhances the selectivity. Alloying Ag into the Pd surface decreases the overall rate but increases the ethylene selectivity significantly by promoting the selective hydrogenation of vinyl to ethylene and concomitantly suppressing the unselective path involving the hydrogenation of vinyl to ethylidene and the dehydrogenation of ethylidene to ethylidyne. This is consistent with experimental results which suggest that only the predominant hydrogenation path which involves the sequential addition of hydrogen to form vinyl and ethylene exists over the Pd-Ag alloys. Ag enhances the desorption of ethylene and hydrogen from the surface thus limiting their ability to undergo subsequent reactions. The simulated apparent activation barriers were calculated to be 32-44 kJ/mol on Pd(1 1 1) and 26-31 kJ/mol on Pd-Ag/Pd(1 1 1), respectively. The reaction was found to be essentially first order in hydrogen and -0.4 and -0.21 order in acetylene over Pd(1 1 1) and Pd-Ag/Pd(1 1 1) surfaces, respectively. The results reveal that increases in the hydrogen partial pressure increase the activity but decrease ethylene selectivity over both Pd and Pd-Ag/Pd(1 1 1) surfaces. (c) 2009 Elsevier Inc.

AB Direct numerical simulation (DNS) of the near field of a three-dimensional spatially developing turbulent lifted hydrogen jet flame in heated coflow is performed with a detailed mechanism to determine the stabilization mechanism and the flame structure. The DNS was performed at a jet Reynolds number of 11000 with over 940 million grid points. The results show that auto-ignition in a fuel-lean mixture at the flame base is the main Source of stabilization of the lifted Jet flame. A chemical flux analysis shows the occurrence of near-isothermal chemical chain branching preceding thermal runaway upstream of the stabilization point, indicative of hydrogen auto-ignition in the second limit. The Damkohler number and key intemediate-species behaviour near the leading edge of the lifted flame also verify that auto-ignition occurs at the flame base. At the lifted-flame base, it is found that heat release occurs predominantly through ignition in which the gradients of reactants are opposed. Downstream of the flame base, both rich-premixed and non-premixed flames develop and coexist with auto-ignition. In addition to auto-ignition, Lagrangian tracking of the flame base reveals the passage of large-scale flow Structures and their correlation with the fluctuations of the flame base. In particular, the relative position of the flame base and the coherent flow structure induces a cyclic motion of the flame base in the transverse and axial directions about a mean lift-off height. This is confirmed by Lagrangian tracking of key scalars, heat release rate and velocity at the stabilization point.

AB Molecular dynamics simulations were performed with a potential shell model to investigate the diffusion of lithium ions and electron polarons in rutile and anatase. Simulations of an isolated lithium ion in rutile predict fast diffusion in the c channels with an activation energy of 0.05 eV, which corresponds to a jump rate of 4 x 10(11) s(-1) and a diffusion coefficient of 9 x 10(-5) cm(2).s(-1) at room temperature. In anatase, the activation energies for intra- and interoctahedron lithium hopping are 0.02 and 0.39 eV, respectively, and the lithium diffusion coefficient is 4-5 orders of magnitude slower than in rutile. When in the presence of an electron polaron, lithium hopping is predicted to be affected up to four hops away. The effects are more pronounced in rutile; whereby the first energy minimum along the c direction is absent due to the strong lithium-electron electrostatic interactions along the open c channels. Combining the lithium and electron polaron hopping rates, a Coupled diffusion mechanism emerges whereby the electron polarons hop rapidly back and forth around the lithium ions. This process can lead to the occurrence of an instantaneous driving force for lithium hopping. The lithium ion-electron polaron binding energies are found to be large, with a stronger binding in rutile than in as 0.45 and 0.28 eV, respectively, Suggesting that, at low lithium mole fractions, lithium ions and electron polarons will form strongly correlated pairs.

TI A connection between star formation activity and cosmic rays in the
starburst galaxy M82
SO NATURE

DT Article
ID RADIO; EMISSION; CLUSTERS; MODEL
AB Although Galactic cosmic rays (protons and nuclei) are widely believed to be mainly accelerated by the winds and supernovae of massive stars, definitive evidence of this origin remains elusive nearly a century after their discovery(1). The active regions of star-burst galaxies have exceptionally high rates of star formation, and their large size-more than 50 times the diameter of similar Galactic regions-uniquely enables reliable calorimetric measurements of their potentially high cosmic-ray density(2). The cosmic rays produced in the formation, life and death of massive stars in these regions are expected to produce diffuse gamma-ray emission through interactions with interstellar gas and radiation. M82, the prototype small starburst galaxy, is predicted(3,4) to be the brightest starburst galaxy in terms of gamma-ray emission. Here we report the detection of >700-GeV gamma-rays from M82. From these data we determine a cosmic-ray density of 250 eV cm(-3) in the starburst core, which is about 500 times the average Galactic density. This links cosmic-ray acceleration to star formation activity, and suggests that supernovae and massive-star winds are the dominant accelerators.

AB Surface-functionalized polymeric nanoparticles were prepared by: a) self-assembly of poly(4-vinyl-benzocyclobutene-b-butadiene) diblock copolymer (PVBCB-b-PB) to form spherical micelles (diameter: 15-48 nm) in decane, a selective solvent for PB, b) crosslinking of the PVBCB core through thermal dimerization at 200-240 degrees C, and c) cleavage of the PB corona via ozonolysis and addition of dimethyl sulfide to afford aldehyde-functionalized nanoparticles (diameter: similar to 16-20 nm), along with agglomerated nanoparticles ranging from similar to 30 to similar to 100 nm in diameter. The characterization of the diblock copolymer precursors, the intermediate micelles and the final surface-functionalized crosslinked nanoparticles was carried out by a combination of size exclusion chromatography, static and dynamic light scattering, viscometry, thermogravimetric analysis, (1)H NMR and FTIR spectroscopy and transmission electron rnicroscopy.

AB The hysteresis behaviour of multigraft (MG) copolymers, with a polyisoprene backbone and polystyrene (PS) side chains, was investigated by applying a modified softening model proposed by Elias-Zuniga, which uses an approach of Ogden and Roxburgh. The model was combined with the non-affine tube model of rubber elasticity of Kaliske and Heinrich. Four parameters are obtained: chemical and physical cross-link moduli (G(c), G(e)) the number of statistical segments between two successive entanglements (n(e)/T(e)) and a softening parameter (b). The model was proven to be valid by a comparison with other methods evaluating hysteresis behaviour The characterization of the multigraft copolymers revealed a branch point and molecular architecture dependence of the softening parameter. b was low for tetrafunctional MG copolymers with cylindrical microdomains, and it was further reduced for a spherical morphology and for more complex Molecular architectures. The magnitude of b also depends on the PS arm molecular weight for hexa- and tetrafunctional multigraft copolymers. (C) 2009 Elsevier Ltd. All rights reserved.

AB This paper describes a simple, vapor-phase route for the synthesis of metastable alpha-phase copper (sic)thalocyanine (CuPc) single-crystal nanowires through control of the growth temperature. The influence of the growth temperature on the crystal structures, morphology, and size of the CuPc nanostructures is explored using X-ray diffraction (XRD), optical absorption, and transmission electron microscopy (TEM). alpha-CuPc nanowires are successfully incorporated as active semiconductors in field-effect transistors (FETs). Single nanowire devices exhibit carrier mobilities and current on/off ratios as high as 0.4 cm(2) V-1 s(-1) and >10(4), respectively.

AB Hyperbranched aminosilica (HAS) adsorbents are prepared via ring-opening polymerization of aziridine in the presence of mesoporous silica SBA-15 support. The aminopolymers are covalently bound to the silica support and capture CO2 reversibly in a temperature swing process. Here, a range of HAS materials are prepared with different organic loading. The effects of organic loading on the structural properties and CO2 adsorption properties of the resultant hybrid materials are examined. The residual porosity in the HAS adsorbents after organic loading, as well as the molecular weights and degrees of branching for the separated aminopolymers, are determined to draw a relationship between adsorbent structure and performance. Humid adsorption working capacities and apparent adsorption kinetics are determined from experiments in a packed-bed flow system monitored by mass spectrometry. Dry adsorption isotherms are presented for one HAS adsorbent with a high amine loading at 35 and 75 degrees C. These combined results establish the relationships between adsorbent synthesis, structure, and CO2 adsorption properties of the family of HAS materials.

AB The compounds Sc3N@(C-80-I-h(7))(CF3)(14) and Sc3N@(C-80-I-h(7))(CF3)(16) (2) were prepared by heating Sc3N@C-80-I-h(7) and Ag(CF3CO2) to 350 degrees C in a sealed tube. The structures of 1 and 2 were determined by single-crystal X-ray diffraction. They are the first X-ray structures of any endohedral metallofullerene with more than four cage C(sp(3)) atoms. The structures exhibit several unprecedented features for metallic nitride fullerenes, including multiple cage sp(3) triple-hexagon junctions (four on 1 and eight on 2), no cage disorder and little (2) or no (1) endohedral atom disorder, high-precision (C-C esd's are 0.005 angstrom for 1 and 0.002 angstrom for 2), an isolated aromatic C(sp(2))(6) hexagon on 2, and two negatively charged isolated aromatic C(Sp(2))(5)(-) pentagons on 2 that are bonded to one of the Sc atoms. DFT calculations are in excellent agreement with the two Sc3N conformations observed for 2 (Delta E(calc) = 0.36 kJ mol(-1); Delta E(exp) = 0.26(2) kJ mol(-1)).

AB We synthesized, at room temperature, noble multi-metallic (Pt-Pd-Rh, and Pt-Pd-Au-Rh) ultrathin nanowires using a one-step phase-transfer approach. These multi-metallic nanowires then were characterized by x-ray diffraction, transmission electron microscopy, and scanning transmission electron microscopy. The diameters of the nanowires range from 2 to 2.7 nm, and their lengths from tens to hundreds of nanometers. The multi-metallic nanowires were determined to be face-centered cubic structures. The compositions of the nanowires are quite uniform from wire to wire. Our results verify that the phase-transfer is a robust method for synthesizing various multi-metallic nanowires, which are expected to have potential applications in catalysis, magnetic storage, and bio-sensors.

AB We report on the energetic and structural stability of configuration-tunable, bi-directional linear bearings based on cap-less, partial segments engineered within individual multi-walled carbon nanotubes (MWNTs). Using computational models, we show that an externally applied excitation force can be used to select an operating bearing configuration with a desired stiffness and operating frequency. Our models also demonstrate the possibility of simultaneous, independent operation of multiple bearings within a single NT segment, paving the way towards ultra-high device densities with molecular-scale footprints.

AB Siderite (FeCO3) forms a complete solid solution with magnesite (MgCO3), the most likely candidate for a mantle carbonate. Our experiments with natural siderite reveal spin pairing of d-orbital electrons of Fe2+ at 43 GPa, as evidenced by a sharp volume collapse of about 10%. The initially colorless crystals assume an intense green color after the transition, which progressively turns to red above 60 GPa. We present clear evidence for the instability of an intermediate spin state in siderite at ambient temperature. At the transition pressure, domains of high and low spin siderite coexist. The unit cell volume difference between magnesite and siderite is significantly decreased by the spin transition, enhancing the solubility between the two calcite-type minerals. A siderite component in magnesite at lower mantle pressure would significantly increase its density and slightly increase the carbonate bulk modulus. Citation: Lavina, B., P. Dera, R. T. Downs, V.

TI Reanalysis of relativistic radiation belt electron phase space density

AB Using empirical external magnetic field models (T89, T96, T01s, and T04s) and simultaneous observations from four satellites (CRRES, Akebono, and two GEO satellites) during a 7-day period from 1 to 7 August 1991, we performed a combined reanalysis of radiation belt electron phase space density (PSD). While precise L* locations of the satellites are sensitive to the adopted magnetic field model, comparisons between the reconstructed radial profiles of electron PSD, obtained using Kalman filtering, indicate that the combined reanalyses are relatively insensitive to the choice of the magnetic field model during geomagnetically quiet or moderate activity times or for the long-term reanalysis studies. The reanalysis results using the four external magnetic field models show similarities in the locations of peaks in radial profiles of PSD and the radial extent of the dropouts. The largest difference between assimilated PSD using different Tsyganenko models occurs mostly during geomagnetically active periods when the Dst index is low or at higher L* shells near the boundary. Presented results also suggest that the errors of assimilated PSD based on multiple satellite measurements can become smaller than errors of PSD reconstructed from individual satellites.

AB While polymers hold significant potential as low cost, mechanically flexible, lightweight large area pholovoltaics and light emitting devices (OLEDs), their performance relies crucially on understanding and controlling the morphology oil the nanometer scale. The ca. 10 nm length scale of exciton diffusion sets the patterning length scale necessary to affect charge separation and overall efficiency in photovoltaics. Moreover, the imbalance of electron and hole mobilities in most organic materials necessitates the use of multiple components in many device architectures. These requirements for 10 nm length scale patterning in large area, solution processed devices Suggest that block copolymer strategies previously employed for more classical, insulating polymer systems may be very useful in organic electronics. This Perspective seeks to describe both the synthesis and self-assembly of block copolymers for organic optoelectronics. Device characterization of these inherently complex active layers remains a significant challenge and is also discussed.

X-ray crystal structure determinations for the free ligand 5 and for one complex, [La(5)(6)] (NO3)(3)center dot 7H(2)O, have been completed and the latter reveals an unexpected bidentate chelation mode for 5 that involves the amide carbonyl oxygen atom and the 2-hydroxy oxygen atom of each ligand. The six bidentate ligands generate an icosohedral inner coordination sphere. The N-oxide oxygen atom of each ligand also hydrogen bonds with a 2-hydroxyl hydrogen atom in a neighboring ligand molecule in the same molecular unit. (C) 2009 Elsevier Ltd. All rights reserved.

AB The delivery of signals from the activated T cell antigen receptor (TCR) inside the cell relies on the protein tyrosine kinase ZAP-70 (zeta-associated protein of 70 kDa). A recent crystal structure of inactive full-length ZAP-70 suggests that a central interface formed by the docking of the two SH2 domains of ZAP-70 onto the kinase domain is crucial for suppressing catalytic activity. Here we validate the significance of this autoinhibitory interface for the regulation of ZAP-70 catalytic activity and the T cell response. For this purpose, we perform in vitro catalytic activity assays and binding experiments using ZAP-70 proteins purified from insect cells to examine activation of ZAP-70. Furthermore, we use cell lines stably expressing wild-type or mutant ZAP-70 to monitor proximal events in T cell signaling, including TCR-induced phosphorylation of ZAP-70 substrates, activation of the MAP kinase pathway, and intracellular Ca(2+) levels. Taken together, our results directly correlate the stability of the autoinhibitory interface with the activation of these key events in the T cell response.

AB The proton transfer reaction between the substrate nitroethane and Asp-402 catalyzed by nitroalkane oxidase and the uncatalyzed process in water have been investigated using a path-integral free-energy perturbation method. Although the dominating effect in rate acceleration by the enzyme is the lowering of the quasiclassical free energy barrier, nuclear quantum effects also contribute to catalysis in nitroalkane oxidase. In particular, the overall nuclear quantum effects have greater contributions to lowering the classical barrier in the enzyme, and there is a larger difference in quantum effects between proton and deuteron transfer for the enzymatic reaction than that in water. Both experiment and computation show that primary KIEs are enhanced in the enzyme, and the computed Swain-Schaad exponent for the enzymatic reaction is exacerbated relative to that in the absence of the enzyme. In addition, the computed tunneling transmission coefficient is approximately three times greater for the enzyme reaction than the uncatalyzed reaction, and the origin of the difference may be attributed to a narrowing effect in the effective potentials for tunneling in the enzyme than that in aqueous solution.

Organic light-emitting diodes (OLEDs) with 5% Pt(ptp)(2):HM-A1 attain peak power efficiency of 61.2 lm/W, versus 40.8 lm/W for analogous devices employing the standard turquoise-blue phosphor bis[4,6-difluorophenyl)-pyridinato-N,C-2'](picolinato)iridium(III) (FIrpic). Devices with x% Pt (ptp)(2): HM-A1 exhibit blue emission maxima (lambda(max) similar to 480 nm) with monotonic increase in excimer/monomer intensity ratio at higher doping levels within 1%-10%, causing color shift toward green and less charge balance. This work represents a significant step toward optimizing future white OLEDs from the same phosphor via combination of low-doped and higher-doped or neat films.

AB A protrusion electrode structure is proposed to dramatically lower the operation voltage of the emerging blue-phase liquid crystal displays (BP-LCDs). Simulation results indicate that the generated horizontal electric field is not only strong but also penetrates deeply into the bulk LC layer. As a result, a low voltage (similar to 10 V(rms)) and reasonably high transmittance (similar to 70%) BP-LCD can be achieved. This approach enables the BP-LCDs to be addressed by amorphous silicon thin-film transistors (TFTs). Widespread application of TFT BP-LCDs is foreseeable.

AB Composite specimens possessing polyhedral segregated network microstructures require a very small amount of nanosize filler, <1 vol %, to reach percolation because percolation occurs by accumulation of the fillers along the edges of the deformed polymer matrix particles. In this paper, electrostatic force microscopy (EFM) and conductive atomic force microscopy (C-AFM) were used to confirm the location of the nanosize fillers and the corresponding percolating paths in polymethyl methacrylate/carbon black composites. The EFM and C-AFM images revealed that the polyhedral polymer particles were coated with filler, primarily on the edges as predicted by the geometric models provided.

AB A single-shot, nondestructive, electro-optical, electron bunch length monitor is experimentally verified by encoding the Coulomb field of the bunch profile on the spatial intensity distribution of an unchirped femtosecond laser pulse in an orthogonal geometry, hence a temporal-to-spatial transformation. This electron bunch measurement scheme can simultaneously measure large timing jitter (approximately in picoseconds) with a wide measurement time span covering picosecond to subpicosecond ranges.

TI Direct-current effects on magnetization reversal properties of
submicron-size Permalloy patterns for radio-frequency devices
SO APPLIED PHYSICS LETTERS
LA English
DT Article
ID ARRAYS; FILMS
AB Ferromagnetic resonance (FMR) spectroscopy is used to measure direct-current (dc) effects on the magnetization reversal properties of submicron-sized lateral patterned magnetic material. The observed FMR frequency-field relationship shows that for both 240 and 550 nm wide Permalloy (Py) nanowires the coercivity is reduced by similar to 33% when a 50 mA dc passes through the transmission line where the nanowires are incorporated. The temperature dependence of the coercivity has a root T relationship which suggests the coherent rotation mode tendency in such 100 nm thick Py nanowires. (C) 2009 American Institute of Physics.

AB Laser flash photolysis is applied to study the recombination reaction of lophyl radicals in ionic liquids in comparison with dimethylsulfoxide as an example of a traditional organic solvent. The latter exhibits a similar micropolarity as the ionic liquids. The ionic liquids investigated are 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (1), 1-hexyl-3-methylimidazolium hexafluorophosphate (2), and 1-butyl-3-methylimidazolium tetafluoroborate (3). The recombination of the photolytic generated lophyl radicals occur significantly faster in the ionic liquids than expected from their macroscopic viscosities and is a specific effect of these ionic liquids. On the other hand, this reaction can be compared with the macroscopic viscosity in the case of dimethylsulfoxide. Activation parameters obtained for lophyl radical recombination suggest different, anion-dependent mechanistic effects. Quantum chemical calculations based on density functional theory provide a deeper insight of the molecular properties of the lophyl radical and its precursor. Thus, excitation energies, spin densities, molar volumes, and partial charges are calculated. Calculations show a spread of spin density over the three carbon atoms of the imidazolyl moiety, while only low spin density is calculated for the nitrogens.

The Eu3+ coordination chemistry, solution thermodynamic stability, and photophysical properties of the spermine-based hydroxypyridonate octadentate chelator 3,4,3-LI(1,2-HOPO) are reported. The complex [Eu-III(3,4,3-LI(1,2-HOPO))](-) luminesces with a long lifetime (805 mu s) and a quantum yield of 7.0% in aqueous solution, at pH 7.4. These remarkable optical properties were exploited to determine the high (and proton-independent) stability of the complex (log beta(110) = 20.2(2)) and to define the influence of the ligand scaffold on the stability and photophysical properties.

Remarkably, the dense but electron-poorer blocks of Au tetrahedra coexist with more open and saturated Au-Sn layers, which are fragments of a zinc blende type structure that maximize tetrahedral heteroatomic bonding outside of the network of gold tetrahedra. LMTO band structure calculations reveal metallic properties and a pseudogap at 256 valence electrons per formula unit, only three electrons fewer than in the title compound and at a point at which strong Au-Sn bonding is optimized. Additionally, the tight coordination of the Au framework atoms by K plays an important bonding role: each Au tetrahedra has 10 K neighbors and each K atom has 8-12 Au contacts. The appreciably different role of the p element Sn in this structure from that in the triel members in K3Au5In and Rb2Au3TI appears to arise from its higher electron count which leads to better p-bonding (valence electron concentrations = 1.32 versus 1.22).

AB The static dipole polarizabilities of water clusters (2 <= N <= 12) are determined at the coupled-cluster level of theory (CCSD). For the dipole polarizability of the water monomer it was determined that the role of the basis set is more important than that of electron correlation and that the basis set augmentation converges with two sets of diffuse functions. The CCSD results are used to benchmark a variety of density functionals while the performance of several families of basis sets (Dunning, Pople, and Sadlej) in producing accurate values for the polarizabilities was also examined. The Sadlej family of basis sets was found to produce accurate results when compared to the ones obtained with the much larger Dunning basis sets. It was furthermore determined that the PBE0 density functional with the aug-cc-pVDZ basis set produces overall remarkably accurate polarizabilities at a moderate computational cost.

ID SELF-DIRECTED GROWTH; SILICON; CHEMISTRY; DYNAMICS
AB We revisit the molecular line growth mechanism of styrene on the hydrogenated Si (001) 2 X 1 surface. In particular, we investigate the energetics of the radical chain reaction mechanism by means of diffusion quantum Monte Carlo (QMC) and density functional theory (DFT) calculations. For the exchange correlation (XC) functional we use the nonempirical generalized-gradient approximation (GGA) and meta-GGA. We find that the QMC result also predicts the intra-dimer-row growth of the molecular line over the inter-dimer-row growth, supporting the conclusion based on DFT results. However, the absolute magnitudes of the adsorption/reaction energies and the heights of the energy barriers differ considerably between the QMC and DFT with the GGA/meta-GGA XC functionals.

AB In the factorized picture of semi-inclusive deep inelastic scattering the naive time reversal-odd parton distributions exist by virtue of the gauge link which is intrinsic to their definition. The link structure describes initial/final-state interactions of the active parton due to soft gluon exchanges with the target remnant. Though these interactions are non-perturbative, calculations of final-state interaction have been performed in a perturbative one-gluon approximation. We include higher-order contributions by applying non-perturbative eikonal methods to calculate the Boer-Mulders function of the pion. Using this framework we explore under what conditions the Boer Mulders function can be described in terms of factorization of final state interactions and a spatial distortion.

AB The present knowledge about nontrivial relations between generalized parton distributions for a spin-1/2 hadron on the one hand and transverse momentum dependent distributions on the other is reviewed. While various relations can be found in the framework of simple spectator models, so far no model-independent nontrivial relations have been established. In fact, by relating the two types of parton distributions to the fully unintegrated, off-diagonal quark-quark correlator for a spin-1/2 hadron, we argue that none of the nontrivial relations can be promoted to a model-independent status.

AB After a brief introduction to Deep Inelastic Scattering in the Bjorken limit and in the Regge Limit we discuss the operator product expansion in terms of non local string operator and in terms of Wilson lines. We will show how the high-energy behavior of amplitudes in gauge theories can be reformulated in terms of the evolution of Wilson-line operators. In the leading order this evolution is governed by the non-linear Balitsky-Kovchegov (BK) equation. In order to see if this equation is relevant for existing or future deep inelastic scattering (DIS) accelerators (like Electron Ion Collider (EIC) or Large Hadron electron Collider (LHeC)) one needs to know the next-to-leading order (NLO) corrections. In addition, the NLO corrections define the scale of the running-coupling constant in the BK equation and therefore determine the magnitude of the leading-order cross sections. In Quantum Chromodynamics (QCD), the next-to-leading order BK equation has both conformal and non-conformal parts. The NLO kernel for the composite operators resolves in a sum of the conformal part and the running-coupling part. The QCD and N = 4 SYM kernel of the BK equation is presented.

Weakly confined Zenneck waves on a metal-dielectric interface at terahertz frequencies can be transformed to a strongly confined yet low-loss subwavelength mode through coupling with a photonic mode of a nearby high-index dielectric strip. We analyze confinement, attenuation, and dispersion properties of this mode. The proposed design is suitable for planar integration and allows easy fabrication on chip scale. The superior waveguiding properties at terahertz frequencies could enable the hybrid terahertz waveguides as building blocks for terahertz integrated circuits. (C) 2009 Optical Society of America

TI phi(FLIM)-F-2: a technique for alias-free frequency domain fluorescence
lifetime imaging

AB A new approach to alias-free wide-field fluorescence lifetime imaging in the frequency domain is demonstrated using a supercontinuum source for fluorescence excitation and a phase-modulated image intensifier for detection. This technique is referred to as phi-squared fluorescence lifetime imaging (phi(FLIM)-F-2). The phase modulation and square-wave gating of the image intensifier eliminate aliasing by the effective suppression of higher harmonics. The ability to use picosecond excitation pulses without aliasing expands the range of excitation sources available for frequency-domain fluorescence lifetime imaging (fd-FLIM) and improves the modulation depth of conventional homodyne fd-FLIM measurements, which use sinusoidal intensity modulation of the excitation source. The phi(FLIM)-F-2 results are analyzed using AB-plots, which facilitate the identification of mono-exponential and multi-exponential fluorescence decays and provide measurements of the fluorophore fractions in two component mixtures. The rapid acquisition speed of the technique enables lifetime measurements in dynamic systems, such as temporally evolving samples and samples that are sensitive to photo-bleaching. Rapid phi(FLIM)-F-2 measurements are demonstrated by imaging the dynamic mixing of two different dye solutions at 5.5 Hz. The tunability of supercontinuum radiation enables excitation wavelength resolved FLIM measurements, which facilitates analysis of samples containing multiple fluorophores with different absorption spectra.

TI Direct observation of the transfer of orbital angular momentum to metal
particles from a focused circularly polarized Gaussian beam
SO OPTICS EXPRESS
LA English
DT Article
ID FIELD
AB It is well known that a circularly polarized Gaussian beam carries spin angular momentum, but not orbital angular momentum. This paper demonstrates that focusing a beam carrying spin angular momentum can induce an orbital angular momentum which we used to drive the orbital motion of a micron-sized metal particle that is trapped off the beam axis. The direction of the orbital motion is controlled by the handedness of the circular polarization. The orbiting dynamics of the trapped particle, which acted as an optical micro-detector, were quantitatively measured and found to be in excellent agreement with the theoretical predictions.

Almost-invariant tori
ID MAGNETIC-FIELD; MAPS
AB Two candidates for "almost-invariant" toroidal surfaces passing through magnetic islands, namely quadratic-flux-minimizing (QFMin) surfaces and ghost surfaces, use families of periodic pseudo-orbits (i.e. paths for which the action is not exactly extremal). QFMin pseudo-orbits. which are coordinate-dependent, are field lines obtained from a modified magnetic field, and ghost-surface pseudo-orbits are obtained by displacing closed field lines in the direction of steepest descent of magnetic action, closed integral A.dl. A generalized Hamiltonian definition of ghost surfaces is given and specialized to the usual Lagrangian definition. A modified Hamilton's Principle is introduced that allows the use of Lagrangian integration for calculation of the QFMin pseudo-orbits. Numerical calculations show QFMin and Lagrangian ghost surfaces give very similar results for a chaotic magnetic field perturbed from an integrable case, and this is explained using a perturbative construction of an auxiliary poloidal angle for which QFMin and Lagrangian ghost surfaces are the same up to second order. While presented in the context of 3-dimensional magnetic field line systems, the concepts are applicable to defining almost-invariant tori in other 1 1/2 degree-of-freedom nonintegrable Lagrangian/Hamiltonian systems.

AB We present a search for charged Higgs bosons in top quark decays. We analyze the e + jets, mu + jets, ee, e mu, mu mu, tau e and tau mu final states from top quark pair production events, using data from about 1 fb (1) of integrated luminosity recorded by the DO experiment at the Fermilab Tevatron Collider. We consider different scenarios of possible charged Higgs boson decays, one where the charged Higgs boson decays purely hadronically into a charm and a strange quark, another where it decays into a tau lepton and a tau neutrino and a third one where both decays appear. We extract limits on the branching ratio B(t -> H(+)b) for all these models. We use two methods, one where the t (t) over bar production cross section is fixed, and one where the cross section is fitted simultaneously with B(t -> H(+)b). Based on the extracted limits, we exclude regions in the charged Higgs boson mass and tan beta parameter space for different scenarios of the minimal supersymmetric standard model.

TI The impacts of pretreatment on the fermentability of pretreated
lignocellulosic biomass: a comparative evaluation between ammonia fiber
expansion and dilute acid pretreatment

AB Background: Pretreatment chemistry is of central importance due to its impacts on cellulosic biomass processing and biofuels conversion. Ammonia fiber expansion (AFEX) and dilute acid are two promising pretreatments using alkaline and acidic pH that have distinctive differences in pretreatment chemistries.
Results: Comparative evaluation on these two pretreatments reveal that (i) AFEX-pretreated corn stover is significantly more fermentable with respect to cell growth and sugar consumption, (ii) both pretreatments can achieve more than 80% of total sugar yield in the enzymatic hydrolysis of washed pretreated solids, and (iii) while AFEX completely preserves plant carbohydrates, dilute acid pretreatment at 5% solids loading degrades 13% of xylose to byproducts.
Conclusion: The selection of pretreatment will determine the biomass-processing configuration, requirements for hydrolysate conditioning (if any) and fermentation strategy. Through dilute acid pretreatment, the need for hemicellulase in biomass processing is negligible. AFEX-centered cellulosic technology can alleviate fermentation costs through reducing inoculum size and practically eliminating nutrient costs during bioconversion. However, AFEX requires supplemental xylanases as well as cellulase activity. As for long-term sustainability, AFEX has greater potential to diversify products from a cellulosic biorefinery due to lower levels of inhibitor generation and lignin loss.

Their structures have been established from single-crystal and powder X-ray crystallography: orthorhombic space group Cmcm (No. 63) with cell parameters a = 4.1057(6) angstrom, b = 35.992(5) angstrom, c = 4.2534(6) angstrom for Nd-2[SnxGe1-x](5): a = 4.0707(8) angstrom, b = 35.550(7) angstrom, c = 4.2095(8) angstrom for Sm-2[SnxGe1-x](5); a = 4.2248(11) angstrom, b = 30.451(8) angstrom, c = 4.0013(11) angstrom for Gd[SnxGe1-x](2), and a = 4.1936(13) angstrom, b = 30.230(9) angstrom, c = 3.9793(12) angstrom for Tb[SnxGe1-x](2), respectively. The structures of the two families can be described as being stacking variants of the ZrSi2 and DyGe3 types, respectively. They represent another example of site preferences between two group 14 elements, where the lighter Ge atoms preferentially form zig-zag chains while the square sheets (or double square sheets) are made up of Sn atoms, respectively. Magnetic susceptibility measurements show that all of the compounds order antiferromagnetically at low temperatures and their respective ordering temperatures are further corroborated by specific heat measurements.

AB Reported are the synthesis, crystal structure determination and magnetic properties of new polymorphic forms of the rare-earth metal germanides Tb3Ge5 and Dy3Ge5. Both compounds are isostructural and crystallize with the hexagonal space group P (6) over bar 2c (No. 190, Z = 2) with unit-cell parameters a = 6.861(2) angstrom; c = 8.339(6) angstrom for Tb3Ge5 and a = 6.8387(10) angstrom; c = 8.293(2) angstrom for Dy3Ge5, respectively. The structures are derivatives of the ubiquitous AlB2 type and can be regarded as its 6-fold superstructure (a' = a x 3(1/2) and c' = c x 2), arising from the long range ordering of Ge vacancies. They are therefore best described as flat Ge-layers, stacked in a hexagonal close-packed manner along the crystallographic c-axis, which are separated by layers of rare-earth metal atoms. Magnetic susceptibility measurements reveal that both Tb3Ge5 and Dy3Ge5 exhibit anti ferro magnetic order at temperatures below 23 K and 9 K, respectively. (C) 2008 Elsevier B.V. All rights reserved.

AB The spontaneous generation of voltage (SGV) in single crystalline Tb5Si2.2Ge1.8 and Gd has been studied. Temperature-induced SGVs were observed along the three principal crystallographic axes of Tb5Si2.2Ge1.8, but not in Gd. Field-induced SGVs were observed with magnetic fields less than 40 kOe applied along the a-axis of TB5Si2.2Ge1.8, and the c-axis of Gd. The absence of the temperature-induced SGV in Gd indicates the key role first-order phase transformations play in the appearance of the effect when temperature varies. The anisotropy of the magnetic field-induced SGV in Tb5Si2.2Ge1.8 and the existence of the field-induced SGV in Gd, highlight the importance of the magnetocaloric effect in bringing about the SGV.

AB Measurements of the upper critical field H-c2 Of the Pu-based heavy-fermion superconductor PuRhGa5 have been made using a torque magnetometer at temperatures down to 0.6 K and magnetic fields up to 17T along the principal axes of the tetragonal structure. A linear temperature dependence of H-c2 down to T-c/10 for H parallel to c and to T-c/2 for H parallel to ab is observed. While the data appear to be inconsistent with both purely Pauli limiting or orbital effects governing the upper critical field, the linear T-dependence of H-c2 is well described by a two-band model of superconductivity involving coupled bands of heavy and light electrons. A close similarity between PuRhGa5 and the pressure-induced antiferromagnetic isostructural superconductor CeRhIn5 is also found. Published by Elsevier B.V.

AB To ensure safe storage, plutonium-bearing oxides are stabilized at 950 degrees C for at least two hours in an oxidizing atmosphere. Stabilization conditions are expected to decompose organic impurities, convert metals to oxides, and result in moisture content below 0.5 wt%. During stabilization, the specific surface area is reduced, which minimizes readsorption of water onto the oxide surface. Plutonium oxides stabilized according to these criteria were sampled and analyzed to determine moisture content and surface area. In addition, samples were leached in water to identify water-soluble chloride impurity content. Results of these analyses for seven samples showed that the stabilization process produced low moisture materials (<0.2 wt%) with low surface area (<= 1 m(2)/g). For relatively pure materials, the amount of water per unit surface area corresponded to 1.7-3.4 molecular layers of water. For materials with chloride content >360 ppm, the calculated amount of water per unit surface area increased with chloride content, indicating hydration of hygroscopic salts present in the impure PuO(2)-containing materials. The low moisture, low surface area materials in this study did not generate detectable hydrogen during storage of four or more years. (C) 2009 Elsevier B.V. All rights reserved.

AB DNA polymerase delta (Pol delta) is a multisubunit polymerase that plays an indispensable role in replication from yeast to humans. Pol delta from Saccharomyces cerevisiae is composed of three subunits: Pol3, Pol31, and Pol32. Despite the elucidation of the structures and models of the individual subunits (or portions, thereof), the nature of their assembly remains unclear. We present here a small-angle X-ray scattering analysis of a yeast Pol delta complex (Pol delta(T)) composed of Pol3, Pol31, and Pol32N (amino acids 1-103 of Pol32). From the small angle X-ray scattering global parameters and reconstructed envelopes, we show that Pol delta(T) adopts an elongated conformation with a radius of gyration (R(g)) of similar to 52 angstrom and a maximal dimension of similar to 190 angstrom. We also propose an orientation for the accessory Pol31-Pol32N subunits relative to the Pol3 catalytic core that best agrees with the experimental scattering profile. The analysis also points to significant conformational variability that may allow Pol delta to better coordinate its action with other proteins at the replication fork. (C) 2009 Elsevier Ltd.

Increasing heteroatom substitution of the acene framework induces shorter intermolecular pi-pi stacking distances (shorter than for graphite) probably due to lower van der Waals radius of nitrogen atoms. Hydrogen bonding is also a determining Factor in the ease of compounds containing reduced pyrazine rings. Combined electrochemical, electronic absorption, and computational investigations indicate the Substantial electron deficiency of the compounds composed of fused pyrazine rings. The pyrazinacenes are expected to be good candidates as materials for organic thin film transistors.

AB We present a direct measurement of the width of the W boson using the shape of the transverse mass distribution of W -> e nu candidate events. Data from approximately 1 fb(-1) of integrated luminosity recorded at s=1.96 TeV by the D0 detector at the Fermilab Tevatron pp collider are analyzed. We use the same methods and data sample that were used for our recently published W boson mass measurement, except for the modeling of the recoil, which is done with a new method based on a recoil library. Our result, 2.028 +/- 0.072 GeV, is in agreement with the predictions of the standard model.

AB Momentum imaging experiments on dissociative electron attachment (DEA) to a water molecule are combined with ab initio theoretical calculations of the angular dependence of the quantum mechanical amplitude for electron attachment to provide a detailed picture of the molecular dynamics of dissociation attachment via the two lowest energy Feshbach resonances. The combination of momentum imaging experiments and theory can reveal dissociation dynamics for which the axial recoil approximation breaks down and thus provides a powerful reaction microscope for DEA to polyatomics.

AB A precise measurement of the cross section of the process e(+)e(-)->pi(+)pi(-)(gamma) from threshold to an energy of 3 GeV is obtained with the initial state radiation (ISR) method using 232 fb(-1) of data collected with the BABAR detector at e(+)e(-) center-of-mass energies near 10.6 GeV. The ISR luminosity is determined from a study of the leptonic process e(+)e(-)->mu(+)mu(-)gamma(gamma). The leading-order hadronic contribution to the muon magnetic anomaly calculated using the pi pi cross section measured from threshold to 1.8 GeV is (514.1 +/- 2.2(stat)+/- 3.1(syst))x10(-10).

AB We have found that bent-core liquid crystalline materials show exceptionally large intrinsic flow birefringence in their isotropic liquid phase. This effect is more than 100 times larger than typical values measured for low molecular weight liquid crystals. The specific flow birefringence (i.e., normalized by the flow viscosity) is an order of magnitude larger than in both side-chain polymeric as well as low molecular weight liquid crystals. We propose that this large enhancement for bent-core compounds may be attributed to nanoscale smecticlike clusters that persist above the nematic-isotropic transition temperature, and shear align under shear flow; however, this mechanism has not yet been definitively confirmed.

TI Stability in bcc Transition Metals: Madelung and Band-Energy Effects due
to Alloying
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID CRYSTAL-STRUCTURE; HIGH-PRESSURES; VANADIUM; NB
AB The phase stability of group VB (V, Nb, and Ta) transition metals is explored by first-principles electronic-structure calculations. Alloying with a small amount of a neighboring metal can either stabilize or destabilize the body-centered-cubic phase relative to low-symmetry rhombohedral phases. We show that band-structure effects determine phase stability when a particular group VB metal is alloyed with its nearest neighbors within the same d-transition series. In this case, the neighbor with less (to the left) and more (to the right) d electrons destabilize and stabilize bcc, respectively. When alloying with neighbors of higher d-transition series, electrostatic Madelung energy dominates and stabilizes the body-centered-cubic phase. This surprising prediction invalidates current understanding of simple d-electron bonding that dictates high-symmetry cubic and hexagonal phases.

TI Field-Induced Coupled Superconductivity and Spin Density Wave Order in
the Heavy Fermion Compound CeCoIn5
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
AB The high-field superconducting state in CeCoIn5 has been studied by transverse field muon spin rotation measurements with an applied field parallel to the crystallographic c axis close to the upper critical field mu H-0(c2)=4.97 T. At magnetic fields mu H-0 >= 4.8 T the muon Knight shift is enhanced and the superconducting transition changes from second order towards first order as predicted for Pauli-limited superconductors. The field and temperature dependence of the transverse muon spin relaxation rate sigma reveal paramagnetic spin fluctuations in the field regime from 2 T 1-C(6)H(12)) = (8.76 x 10(17)) exp((-91.94 kcal/mol)/RT) s(-1) (T = 1300-2000 K) and k(infinity)(1-C(6)H(12) -> (center dot)C(3)H(7) + (center dot)C(3)H(5)) = (1.46 x 10(16)) exp((-69.12 kcal/mol)/RT) s(-1) (T = 1200-1700 K). This high-pressure rate for cyclohexane is entirely consistent with the notion that the isomerization involves initial C-C fission to a diradical. These extrapolated high-pressure rates are in good agreement with much of the literature.

AB In recent years, theoretical as well as experimental studies have presented a novel view of the aqueous interface, wherein hard and/or multiply charged ions are excluded from the interface but large polarizable anions show interfacial enhancement relative to the bulk. The observed trend in the propensity of anions to adsorb at the air/water interface appears to follow an inverse order of the Hofmeister series for anions. This study focuses on experimental and theoretical examination of the partitioning behavior of perchlorate (ClO4-) and chloride (Cl-) ions at the air/water interface. We have used ambient pressure X-ray photoelectron spectroscopy to directly probe the interfacial concentrations of ClO4- and Cl- ions in sodium perchlorate and sodium chloride solutions, respectively. In the case Of ClO4- ion, experimental observations are compared with molecular dynamics simulations utilizing both first principles based interaction potentials as well as polarizable classical force fields. Both the experimental and the theoretical results show enhancement Of ClO4- ion at the interface, compared with the absence of such enhancement in the case of the Cl- ion. Our observations are in agreement with the expected trend in the interfacial propensity of anions based on the Hofmeister series.

DT Article
ID CRYSTAL-STRUCTURE; PERFORMANCE; POLYMORPHS; LI2FESIO4; BATTERIES; LI3PO4
AB The candidate cathode material Li2MnSiO4 for lithium-ion cells was synthesized by an all-acetate precursor sol/gel method under a reducing atmosphere at 600, 700, and 800 degrees C. The material prepared at 700 degrees C was a pure phase and had the structural order of Li3PO4 orthorhombic (S.G. Pmn2(1)) phase. The temperature dependence of the molar magnetic Susceptibility of Li2MnSiO4 was found to be consistent with an antiferromagnetic material with a Neel temperature of 12 K. The calculated effective moment confirmed that the observed magnetic behavior involves Mn2+ ions in a high spin configuration in tetrahedral sites. Scanning electron microscopy of Li2MnSiO4 showed large aggregates (10 to 50 mu m) composed of nanosized particles (100-200 nm). The as-prepared material was almost electrochemically inactive despite the presence of 15 wt % carbon additive. The material was treated by carbon coating using cellulose carbon source precursor and particle size reduction using high-energy ball milling. In coin-cell tests, the carbon-coated and ball-milled materials yielded charge capacities of 190 and 172 mAh/g, respectively, under a current density of 10 mA/g. At present, the cationic mixing between Li+ and Mn2+ ions in their mutual crystallographic sites is the main impediment to the achievement of the full theoretical capacity of Li2MnSiO4 (333 mAh/g).

TI Supernova 2007bi as a pair-instability explosion
SO NATURE
LA English
DT Article
ID CORE-COLLAPSE SUPERNOVAE; SPECTRA; STARS
AB Stars with initialmasses such that 10M(circle dot) <= M(initial) <= 100M(circle dot), where M(circle dot) is the solar mass, fuse progressively heavier elements in their centres, until the core is inert iron. The core then gravitationally collapses to a neutron star or a black hole, leading to an explosion-an iron-core-collapse supernova(1,2). By contrast, extremely massive stars with M(initial) >= 140M(circle dot) (if such exist) develop oxygen cores with masses, M(core), that exceed 50M(circle dot), where high temperatures are reached at relatively low densities. Conversion of energetic, pressure-supporting photons into electron-positron pairs occurs before oxygen ignition and leads to a violent contraction which triggers a nuclear explosion(3-5) that unbinds the star in a pair-instability supernova. Transitional objects with 100M(circle dot) < M(initial) < 140M(circle dot) may end up as iron-core-collapse supernovae following violent mass ejections, perhaps as a result of brief episodes of pair instability, and may already have been identified(6-8). Here we report observations of supernova SN 2007bi, a luminous, slowly evolving object located within a dwarf galaxy. We estimate the exploding core mass to be M(core) approximate to 100M(circle dot), in which case theory unambiguously predicts a pair-instability supernova. We show that >3M(circle dot) of radioactive (56)Ni was synthesized during the explosion and that our observations are well fitted by models of pair-instability supernovae(9,10). This indicates that nearby dwarf galaxies probably host extremely massive stars, above the apparent Galactic stellar mass limit(11), which perhaps result from processes similar to those that created the first stars in the Universe.

TI Thermal ion flow in Saturn's inner magnetosphere measured by the Cassini
plasma spectrometer: A signature of the Enceladus torus?
SO GEOPHYSICAL RESEARCH LETTERS

AB For the middle and outer magnetosphere of Saturn (>5.5 R-S), Cassini plasma spectrometer ion counting data provides thermal ion moments by assuming Maxwellian phase space density distributions for each ion species. However, in the inner magnetosphere (<5.5 R-S) within Saturn's extended neutral cloud and proposed Enceladus torus, there is fresh ion production via charge exchange, yielding a complex ion velocity distribution. In this study, ion flow velocities in the inner region are obtained using the assumption that the ion phase space distributions are gyrotropic. Significantly sub-corotating ion flow velocities (similar to 75% of corotation) are found in the vicinity of the Enceladus orbit and the radial extent of the sub-corotation is about 1.0 R-S, in reasonable agreement with the simulated radial dimension of the Enceladus torus.

EFFICIENCY; STORAGE; CYCLES
AB Calcium oxide based materials are attractive regenerable absorbents for separating CO2 from hot gas streams because of their high reactivity, high CO2 capacity, and low material cost. Their high carbonation temperature makes it possible to recover and use high quality heat released during CO2 capture, which increases overall process efficiency. However, the performance of all reported CaO-based absorbents deteriorates as the number of carbonation-decarbonation cycles increases. This is caused by absorbent sintering during the highly exothermic carbonation process. We have found that sintering can be effectively mitigated by properly mixing with a modest amount of MgO. A class of CaO-based absorbents with improved durability and CO2 reactivity were prepared by physical mixing of Ca(CH3COO)(2) with small MgO particles followed by high temperature calcination. With 26 wt % MgO content, a CaO-MgO mixture prepared by this method gives as high as 53 wt % CO2 capacity after 50 carbonation-decarbonation cycles at 758 degrees C. Without MgO addition, the CO2 capacity of pure CaO obtained from the same source decreases from 66 wt % for the first cycle to 26 wt % for the 50th cycle under the same test conditions.

AB A pilot-scale study was conducted to examine the effect of the steam-to-biomass ratio, the gasification temperature, and the thermal cracker temperature for Vermont wood, wheat straw, switchgrass, and corn stover on the formation and speciation of tars. This study is divided into two parts; the first paper detailed the processing conditions and gives quantitative information on low-molecular-weight species. This paper, which is the second part of this study, uses multivariate curve resolution techniques to correlate process variables with the mass spectra gathered during the study to (1) identify the global chemistry of the system and (2) to identify differences or similarities of the product gas streams for each feedstock. Three main groups of products were identified statistically: (1) primary and secondary pyrolysis products (e.g., guaiacol, furfural), (2) cracking products (e.g., phenol, cresol), and (3) polynuclear aromatic hydrocarbons (PAHs). Our findings support known global reaction mechanisms that delineate the formation of the more-refractory PAHs, whereby oxygenated pyrolysis products are cracked into smaller fragments that contain less oxygen. These crack further into small hydrocarbons and radicals that undergo molecular weight growth to produce PAHs. The results from this statistical analysis indicate that, at high temperatures, where PAHs dominate, there is little variation observed between the feedstocks.

AB Despite being one of the oldest known magnetic materials, and the classic mixed valence compound, thought to be charge ordered, the structure of magnetite below the Verwey transition is complex and the presence and role of charge order is still being debated. Here, we present resonant x-ray diffraction data at the iron K-edge on forbidden (0, 0, 2n+1)(C) and superlattice (0, 0, 2n+1/2)(C) reflections. Full linear polarization analysis of the incident and scattered light was conducted in order to explore the origins of the reflections. Through simulation of the resonant spectra we have confirmed that a degree of charge ordering takes place, while the anisotropic tensor of susceptibility scattering is responsible for the superlattice reflections below the Verwey transition. We also report the surprising result of the conversion of a significant proportion of the scattered light from linear to nonlinear polarization.

AB Neutron scattering measurements have been performed on polycrystalline Tb2Sn2O7 at temperatures above and below that of the phase transition, T-N = 0.87 K, to investigate further the spin dynamics in the magnetically ordered state. In particular, new neutron spin echo results are presented showing a dependence on Q in the dynamics. We show evidence of the coexistence of static ferromagnetism and dynamically fluctuating spins down to 30 mK and we make a comparison of this partially ordered system to the spin liquid Tb2Ti2O7.

AB Fullerenes such as C(60) show promise as functional components in several emerging technologies. For biomedical applications, C,, has been used in gene- and drug-delivery vectors, as imaging agents, and as photosensitizers in cancer therapy. A major drawback of C(60) for bioapplications is its insolubility in water. To overcome this limitation, we covalently attachedC(60) derivatives to Cowpea mosaic virus and bacteriophage QB virus-like particles, which are examples of naturally occurring viral nanoparticle (VNP) structures that have been shown to be promising candidates for biomedicine. Two different labeling strategies were employed, giving rise to water-sotuble, stable VNP-C(60) and VNP-PEG-C(60) conjugates. Samples were characterized using a combination of transmission electron microscopy, scanning transmission electron microscopy (STEM), get electrophoresis, size-exclusion chromatography, dynamic light scattering, and Western blotting. "Click" chemistry bioconjugation using a poly(ethylene glycol) (PEG)-modified propargyl-O-PEG-C(60) derivative gave rise to high loadings of fullerene on the VNP surface, as indicated by the imaging of individual C. units using STEM. The cellular uptake of dye-labeled VNP-PEG-C(60) complexes in a human cancer cell Line was found by confocal microscopy to be robust, showing that cell internalization was not inhibited by the attached C(60) units. These results open the door for the development of novel therapeutic devices with potential applications in photoactivated tumor therapy.

AB Single-walled carbon nanotubes (SWNTs) have been investigated for a variety of applications including composite materials, electronics, and drug delivery. However, these applications may be compromised depending on the negative effects of SWNTs to living systems. While reports of toxicity induced by SWNTs vary, means to alleviate or quell these effects are in small abundance. We have reported recently the degradation of carboxylated SWNTs through enzymatic catalysis with horseradish peroxidase (HRP). In this full Article, we investigated the degradation of both carboxylated and pristine SWNTs with HRP and compared these results with chemical degradation by hemin and FeCl(3). The interaction between pristine and carboxylated SWNTs with HRP was further studied by computer modeling, and the products of the enzymatic degradation were identified. By examining these factors with both pristine and carboxylated SWNTs through a variety of techniques including atomic force microscopy (AFM), transmission electron microscopy (TEM), Raman spectroscopy, ultraviolet-visible-near-infrared (UV-vis-NIR) spectroscopy, gas chromatography-mass spectrometry (GC-MS), high-performance liquid chromatography (HPLC), and liquid chromatography-mass spectrometry (LC-MS), degradation pathways were elucidated. It was observed that pristine SWNTs demonstrate no degradation with HRP incubation but display significant degradation when incubated with either hemin or FeCl(3). Such data signify a heterolytic cleavage of H(2)O(2) with HRP as pristine nanotubes do not degrade, whereas Fenton catalysis results in the homolytic cleavage of H(2)O(2) producing free radicals that oxidize pristine SWNTs. Product analysis shows complete degradation produces CO(2) gas. Conversely, incomplete degradation results in the formation of different oxidized aromatic hydrocarbons.

AB We examined the effects of the thickness of the Pt shell, lattice mismatch, and particle size on specific and mass activities from the changes in effective surface area and activity for oxygen reduction induced by stepwise Pt-monolayer depositions on Pd and Pd3Co nanoparticles. The core-shell structure was characterized at the atomic level using Z-contrast scanning transmission electron microscopy coupled with element-sensitive electron energy loss spectroscopy. The enhancements in specific activity are largely attributed to the compressive strain effect based on the density functional theory calculations using a nanoparticle model, revealing the effect of nanosize-induced surface contraction on facet-dependent oxygen binding energy. The results suggest that moderately compressed (111) facets are most conducive to oxygen reduction reaction on small nanoparticles and indicate the importance of concerted structure and component optimization for enhancing core-shell nanocatalysts' activity and durability.

AB In this work we investigate the effects of yarn diameter and gauge length on the statistical strength of yarns spun from carbon nanotubes (CNTs). Tensile tests are conducted on a large sample set of nanostructured CNT yarns. The data show that strength varies substantially and both strength and statistical dispersion in strength decreases as yarn diameter increases. To explain these phenomena and forecast their effects on larger-scale structures, a hierarchical set of Monte Carlo simulation models is developed: the lower-scale model aims to predict the relationship between yarn nanostructure and tensile strength and the higher-scale model aims to relate the strength of CNT yarns to the strength of composites reinforced with unidirectionally aligned CNT yarns. Predictions indicate that, for both structures, the mean and statistical variation in strength will decrease as the surface twist angle, number of CNTs in cross section and gauge length of the yarn increases. The predicted reductions in variability due to yarn nanostructure will be important for determining ways to minimize the detrimental effects of increasing length scale on strength.

Metal/TiO2/metal devices were electroformed with both bias polarities and then physically opened to study the resulting material changes within the device. Soft x-ray absorption techniques allowed isolated study of the different materials present in the device with 100 nm spatial resolution. The resulting morphology and structural changes reveal a picture of localized polarity-independent heating occurring within these devices initiated by and subsequently accelerating polarity-dependent electrochemical reduction/oxidation processes.

AB Bacterial cellulose (BC) is a highly-versatile nanostructured biomaterial with diverse applications including paper products, and in electronic, acoustic, and biomedical devices. This work describes the properties of a novel composite material consisting of calcium-deficient hydroxyapatite (CdHAP) that is biomimetically deposited in a BC hydrogel by sequential incubation in calcium chloride followed by sodium phosphate. The ability of native BC and BC-CdHAP composite to act as a scaffold for growth of osteoblasts, the cells responsible for bone formation in the body, was tested. Results show the cells grow well on both materials, but adhere more strongly to BC-CdHAP compared to the native material. This composite material holds great promise as a biomaterial for bone substitution and regeneration.

AB T he conversion of solar energy to fuels in both natural and artificial photosynthesis requires components for both light-harvesting and catalysis. The light-harvesting component generates the electrochemical potentials required to drive fuel-generating reactions that would otherwise be thermodynamically uphill. This Account focuses on work from our laboratories on developing molecular electrocatalysts for CO2 reduction and for hydrogen production.
A true analog of natural photosynthesis will require the ability to capture CO2 from the atmosphere and reduce it to a useful fuel. Work in our laboratories has focused on both aspects of this problem. Organic compounds such as quinones and inorganic metal complexes can serve as redox-active CO2 carriers for concentrating CO2. We have developed catalysts for CO2 reduction to form CO based on a [Pd(triphosphine)(solvent)](2+) platform. Catalytic activity requires the presence of a weakly coordinating solvent molecule that can dissociate during the catalytic cycle and provide a vacant coordination site for binding water and assisting C-O bond cleavage. Structures of [NiFe] CO dehydrogenase enzymes and the results of studies on complexes containing two [Pd(triphosphine)(solvent)](2+) units suggest that participation of a second metal in CO2 binding may also be required for achieving very active catalysts.
We also describe molecular electrocatalysts for H-2 production and oxidation based on [Ni(diphosphine)(2)](2+) complexes. Similar to palladium CO2 reduction catalysts, these species require the optimization of both first and second coordination spheres. In this case, we use structural features of the first coordination sphere to optimize the hydride acceptor ability of nickel needed to achieve heterolytic cleavage of H-2. We use the second coordination sphere to incorporate pendant bases that assist in a number of important functions including H-2 binding, H-2 cleavage, and the transfer of protons between nickel and solution. These pendant bases, or proton relays, are likely to be important in the design of catalysts for a wide range of fuel production and fuel utilization reactions involving multiple electron and proton transfer steps.
The generation of fuels from abundant substrates such as CO2 and water remains a daunting research challenge, requiring significant advances in new inexpensive materials for light harvesting and the development of fast, stable, and efficient electrocatalysts. Although we describe progress in the development of redox-active carriers capable of concentrating CO2 and molecular electrocatalysts for CO2 reduction, hydrogen production, and hydrogen oxidation, much more remains to be done.

AB The scientific community now agrees that the rise in atmospheric CO(2), the most abundant green house gas, comes from anthropogenic sources such as the burning of fossil fuels. This atmospheric rise in CO(2) results in global climate change. Therefore methods for photochernically transforming CO(2) into a source of fuel could offer an attractive way to decrease atmospheric concentrations. One way to accomplish this conversion is through the light-driven reduction of carbon dioxide to methane (CH(4(g))) or methanol (CH(3)OH((1))) with electrons and protons derived from water. Existing infrastructure already supports the delivery of natural gas and liquid fuels, which makes these possible CO(2) reduction products particularly appealing.
This Account focuses on molecular approaches to photochemical CO(2) reduction in homogeneous solution. The reduction Of CO(2) by one electron to form CO(2)(center dot-) is highly unfavorable, having a formal reduction potential of -2.14 V vs SCE. Rapid reduction requires an overpotential of up to 0.6 V, due at least in part to the kinetic restrictions imposed by the structural difference between linear CO(2) and bent CO(2)(center dot-). An alternative and more favorable pathway is to reduce CO(2) though proton-assisted multiple-electron transfer. The development of catalysts, redox mediators, or both that efficiently drive these reactions remains an important and active area of research.
We divide these reactions into two class types. In Type I photocatalysis, a molecular light absorber and a transition metal catalyst work in concert. We also consider a-special case of Type I photocatalysis, where a saturated hydrocarbon links the catalyst and the light absorber in a supramolecular compound. In Type 11 photocatalysis, the light absorber and the catalyst are the same molecule. In these reactions, transition-metal coordination compounds often serve as catalysts because they can absorb a significant portion of the solar spectrum and can promote activation of small molecules. This Account discusses four classes of transition-metal catalysts: (A) metal tetraaza-macrocyclic compounds; (B) supramolecular complexes; (C) metalloporphyrins and related metallomacrocycles; (D) Re(CO)(3)(bpy)X-based compounds where bpy = 2,2'-bipyridine. Carbon monoxide and formate are the primary CO(2) reduction products, and we also propose bicarbonate/carbonate production. For comprehensiveness, we briefly discuss hydrogen formation, a common side reaction that occurs concurrently with CO(2) reduction, though the details of that process are beyond the scope of this Account. It is our hope that drawing attention both to current mechanistic hypotheses and to the areas that are poorly understood will stimulate research that could one day provide an efficient solution to this global problem.

AB One consistent limitation for high-resolution imaging of small nanoparticles is the high background signal from the amorphous carbon support film. With interest growing for smaller and smaller nanostructures, state of the art electron microscopes are becoming necessary for rudimentary tasks, such as nanoparticle sizing. As a monolayer of carbon, free-standing graphene represents the ultimate support film for nanoparticle imaging. In this work, conventional high-resolution transmission electron microscopy (HRTEM) and aberration-corrected scanning transmission electron microscopy (STEM) were used cc assess the benefits and feasibility of few-layer graphene support films. Suspensions of few-layer graphene to produce the support films were prepared by simple sonication of exfoliated graphite. The greatest benefit was observed for conventional HRTEM, where lattice resolved imaging of sub 2 nm CdSe nanocrystals was achieved. The few-layer graphene films were also used as a support him For C(s)-corrected STEM and electron energy loss spectroscopy of CuInSe(2) nanocrystals.

AB The nematode Caenorhabditis elegans is an excellent model organism for studies of glycan dynamics, a goal that requires tools for imaging glycans in vivo. Here we applied the bioorthogonal chemical reporter technique for the molecular imaging of mucin-type O-glycans in live C elegans. We treated worms with azido-sugar variants of N-acetylglucosamine (GlcNAc), N-acetylgalactosamine (GalNAc), and N-acetylmannosamine (ManNAc), resulting in the metabolic labeling of their cell-surface glycans with azides. Subsequently, the worms were reacted via copper-free click reaction with fluorophore-conjugated difluorinated cyclo-octyne (DIFO) reagents. We identified prominent localization of mucins in the pharynx of all four larval stages, in the adult hermaphrodite pharynx, vulva and anus, and in the tail of the adult male. Using a multicolor, time-resolved imaging strategy, we found that the distribution and dynamics of the glycans varied anatomically and with respect to developmental stage.

AB The development of new and better substrates is a major focus of research aimed at improving the analytical capabilities of surface-enhanced Raman spectroscopy (SERS). Perhaps the most common type of SERS substrate, one consistently exhibiting large enhancements, is simple colloidal gold or silver nanoparticles in the 10-150 nm size range. The colloidal systems that are used most for ultrasensitive detection are generally aggregated clusters that possess "hot spot(s)" within some of the aggregates. A significant limitation of these synthetic substrates is that the "hot' aggregates are extremely difficult to create consistently or predict. Electron beam lithography (EBL) along with combinatorial spectral mapping can be used to overcome this limitation. Our previous work, and that of other researchers, invokes the special capabilities of EBL to design and fabricate periodic, highly ordered nanoparticle arrays for SERS. Building on this work, EBL, in conjunction with ancillary fabrication steps, can be used to create complex patterns that mimic random aggregates. These aggregates, unlike those created by colloidal deposition methods, can be uniquely reproduced within the resolution limits of EBL. In the work reported herein, we use a unique approach to create substrates containing a large number of randomly generated cells with different morphologies that are arrayed on silicon wafers. Instead of isolated metal nanoparticles, these structures resemble the aggregates of colloid. By spectral mapping, we investigate the SERS activity of the combinatorial arrays of cells using probe analytes. Two general categories of shapes are randomly designed in different sizes and densities Into several hundred different 5 mu m square cells. Following fabrication, it is shown that a SERS performance contrast of more than a factor of 44 is achieved among these cells and that the best performing cells can be cloned into uniformly high performing macropatterns of lithographically defined nanoaggregates (LDNAs). In this manner, extended LDNA surfaces with uniform 5 x 10(8) enhancement factors are created. Furthermore, the LDNAs can be further dissected and studied in an effort to increase the SERS enhancement per unit geometric substrate area.

AB Herein, we report on near-infrared (NIR) fluorescent nanoparticles generated from an emergent class of materials we refer to as a Group of Uniform Materials Based on Organic Salts (GUMBOS). GUMBOS are largely frozen ionic liquids, although the concept is more general and is also easily applied to solid ionic materials with melting points in excess of 100 degrees C. Nanoparticles based on GUMBOS (nanoGUMBOS) derived from a NIR fluorophore are prepared using a reprecipitation method and evaluated for in vivo fluorescence imaging. Due to their uniformity, single-step preparation, and composite nature, nanoGUMBOS help to resolve issues with dye leakage problems innate to alternate cellular stains and unlock a myriad of applications for these materials, highlighting exciting possibilities for multifunctional nanoGUMBOS.

AB One-dimensional crystals of 25% C-13-enriched C-60 encapsulated inside highly magnetically purified SWNTs were investigated by following the temperature dependence of the C-13 NMR line shapes and the relaxation rates from 300 K down to 5 K. High-resolution MAS techniques reveal that 32% of the encapsulated molecules, so-called the C-60(alpha), are blocked at room temperature and 68%, labeled C-60(beta), are shown to reversly undergo molecular reorlentational dynamics. Contrary to previous NMR studies, spin - lattice relaxation time reveals a phase transition at 100 K associated with the changes in the nature of the C-60(beta) dynamics. Above the transition, the C-60(beta) exhibits continuous rotational diffusion; below the transition, C-60(beta) executes uniaxial hindered rotations most likely along the nanotubes axis and freeze out below 25 K. The associated activation energies of these two dynamical regimes are measured to be 6 times lower than in fcc-C-60, suggesting a quiet smooth orientational dependence of the interaction between C-60(beta) molecules and the inner surface of the nanotubes.
