Observation of hot luminescence and slow intersubband relaxation in GaN/AlGaN multi-quantum-well structures (2007)

In this work we discuss the optical properties of GaN/AlxGa1−xN (x=0.11, 0.25) multiple‐quantum‐well structures grown by plasma‐assisted molecular‐beam epitaxy. Photoluminescence lines related to the fundamental and excited electronic levels are identified, in good agreement with simulations of the electronic structure. Temperature dependent studies reveal an anomalous behavior of the photoluminescence intensity, which is the quenching of the e1‐hh1 line, while the e2‐hh1 and e3‐hh1 lines become dominant at room temperature in samples with 11% and 25% Al in the barriers, respectively. This behavior is explained by carrier filling of e2 and e3 and by the influence of the internal electric field on the oscillator strength of the different transitions. Long intersubband relaxation times (>40 ps) have been measured as a consequence of the quenching of the longitudinal optical (LO)‐phonon emission when the intersubband transition energy is below the LO‐phonon energy.
PROTINFO: secondary and tertiary protein structure prediction (2003)

Information about the secondary and tertiary structure of a protein sequence can greatly assist biologists in the generation and testing of hypotheses, as well as design of experiments. The PROTINFO server enables users to submit a protein sequence and request a prediction of the three-dimensional (tertiary) structure based on comparative modeling, fold generation and de novo methods developed by the authors. In addition, users can submit NMR chemical shift data and request protein secondary structure assignment that is based on using neural networks to combine the chemical shifts with secondary structure predictions. The server is available at http://protinfo.compbio.washington.edu.

X-Ray photoelectron spectroscopy characteristics of a novel organic semiconductor BTQBT and its derivatives (1995)

X-Ray photoelectron spectra of bis[1,2,5]thiadiazole-p-quinobis(1,3-dithiole)(BTQBT) reveal that the sulfur and carbon atoms in the molecules show four- and two-peak profiles, respectively, and are in mixed-valence states. Substitution of the sulfur atoms linked to nitrogen atoms by selenium atoms removes the mixed valency of sulfur. In systems with asymmetrical molecular skeletons, such as TMBTQBT, TMTBTQBT and DBBTQBT, sulfur and carbon atoms are also in mixed-valence states. TMBTQBT shows the largest energy difference between the C 1s and S 2p peaks, indicating the largest charge distribution. Each of the S 2p and C 1s peaks is accompanied by shake-up satellites located to higher energy at ca. 2.7 eV from the corresponding photoelectron main peak.

An Evaluation of Techniques for Clustering Search Results (2005)

. The ability to effectively organize retrieval results becomes more important as the focus of Information Retrieval (IR) shifts towards interactive search processes. Automatic classification techniques are capable of providing the necessary information organization by arranging the retrieved data into groups of documents with common subjects. In this paper, we compare classification methods from IR and Machine Learning (ML) for clustering search results. Issues such as document representation, classification algorithms, and cluster representation are discussed. We introduce several evaluation techniques and use them in preliminary experiments. These experiments indicate that the proposed techniques have promise, but it is clear that user experiments are required to carry out more thorough evaluation.

Investigation into the Effects of Operating Conditions and Design Parameters on the Creep Life of High Pressure Turbine Blades in a Stationary Gas Turbine Engine (2011)

A physics–based model is used to investigate the relationship between operating conditions\nand design parameters on the creep life of a stationary gas turbine high pressure\nturbine (HPT) blade. A performance model is used to size the blade and to determine its\nstresses. The eﬀects of radial temperature distortion, turbine inlet temperature, ambient\ntemperature and compressor degradation on creep life are then examined. The results\nshow variations in creep life and failure location along the span of the blade enabling\nbetter informed design and maintenance decisions.

Degradation of the polysaccharide component of gonococcal lipopolysaccharide by gonococcal and meningococcal sonic extracts (1978)

An extract made from the supernatant of Neisseria gonorrhoeae Gc2 strain 1291 degraded the Gc2 polysaccharide antigen. Chemical analysis of this polysaccharide indicated it contains glucose, galactose, glucosamine, galactosamine, glucosamine-6-phosphate, heptose, 2-keto-3-deoxyotonate, and ethanolamine and is the polysaccharide component of gonococcal lipopolysaccharide. Degradation of the polysaccharide by sonic extracts resulted either in complete loss of antigenicity and immunogenicity or in partial degradation to subunits that could inhibit the Gc2-specific hemagglutination inhibition. The factors responsible for degradation were destroyed by heating at 100 degrees C for 5 min or by Pronase digestion, but were unaffected by ribonuclease, deoxyribonuclease, Mg2+, Ca2+, or ethylenediaminetetraacetic acid. The process was pH dependent, with optimal activity occurring at pH 7. Sonic extract supernatants from group B and C meningococcal strains contained degrading properties, whereas similar extracts produced from Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, and Streptococcus pneumoniae type II failed to degrade the Gc2 polysaccharide.
Influence of temperature on the calcium sensitivity of the myofilaments of skinned ventricular muscle from the rabbit. (1989)

The steady-state myofilament Ca sensitivity was determined in skinned cardiac trabeculae from the rabbit right ventricle (diameter, 0.13-0.34 mm) at 36, 29, 22, 15, 8, and 1 degree C. Muscles were stimulated to 0.5 Hz and stretched to a length at which maximum twitch tension was generated. The preparation was then skinned with 1% vol/vol Triton X-100 in a relaxing medium (10 mM EGTA, pCa 9.0). Each preparation was exposed to a series of Ca-containing solutions (pCa 6.3-4.0) at two of the six temperatures studied (temperature was regulated to +/- 0.1 degree C). The pCa values (mean +/- SD, n = 6) corresponding to half maximal tension at 36, 29, 22, 15, 8, and 1 degree C were 5.47 +/- 0.07, 5.49 +/- 0.07, 5.34 +/- 0.05, 5.26 +/- 0.09, 4.93 +/- 0.06, and 4.73 +/- 0.04, respectively. Mean (+/- SD) maximum tension (Cmax) developed by the preparation as a percentage of that at 22 degrees C was 118 +/- 10, 108 +/- 5, 74 +/- 6, 57 +/- 7, and 29 +/- 5% at 36, 29, 15, 8, and 1 degree C, respectively. As cooling led to a shift of Ca sensitivity towards higher [Ca2+] and a reduction of Cmax, the Ca sensitivity curves over this range of temperatures do not cross over as has been described for canine Purkinje fibers (Fabiato 1985). Since tension is decreased by cooling at all levels of [Ca2+] it is unlikely that changes in myofilament Ca sensitivity play a role in the large hypothermic inotropy seen in rabbit ventricular muscle. The increase in sensitivity of the myofilaments to Ca on warming from 1 to 29 degrees C might be related to the increase in force seen on rewarming from a rapid cooling contracture in intact rabbit ventricular muscle.
Precursory seismicity changes associated with the 1999 August 17 Izmit (Turkey) earthquake (2002)

We investigated precursory seismicity in and around the epicentral zone of the Mw= 7.4 1999 August 17 Izmit (Turkey) earthquake, by applying a statistical method—the RTL (Region–Time–Length) algorithm—to earthquake catalogues derived from that for the period 1981–1999 of Kandilli Observatory and Earthquake Research Institute (KOERI). The derived catalogues are complete for events MD≥ 3 in most of western Turkey. After declustering aftershocks, we investigated the seismicity patterns preceding the Izmit event at local (Izmit tectonic zone) and national (Turkey) scales. The RTL parameter indicates that a period of seismic quiescence started at the end of 1995 and reached a minimum in December 1996. An activation phase lasting about three months followed. The main shock in Izmit and vicinity did not occur when the seismicity returned to its background level, but occurred with a delay of nearly 2.5 yr. We present a new parameter to quantify the spatial distribution of seismic quiescence. The results from both catalogues indicate that a significant quiescence anomaly appeared in 1996 around the epicenter of the Izmit earthquake. The primary characteristics of the seismicity patterns prior to the Izmit earthquake are similar to those obtained for large events in Russia and Japan. The variations of seismicity patterns revealed by the RTL algorithm may offer better understanding of the physical nature of seismo-tectonics and provide useful information for seismic hazard estimation. The varying characteristics of the Izmit and other events may reflect the difference between seismo-tectonics in Turkey and in other regions such as Russia and Japan.
A NONLINEAR DYNAMICS PERSPECTIVE OF WOLFRAM'S NEW KIND OF SCIENCE PART VI: FROM TIME-REVERSIBLE ATTRACTORS TO THE ARROW OF TIME (2006)

This paper proves, via an analytical approach, that 170 (out of 256) Boolean CA rules in a one-dimensional cellular automata (CA) are time-reversible in a generalized sense. The dynamics on each attractor of a time-reversible rule N is exactly mirrored, in both space and time, by its bilateral twin ruleN † . In particular, all 69 period-1 rules, 17 (out of 25) period-2 rules, and 84 (out of 112) Bernoulli rules are time-reversible. The remaining 86 CA rules are time-irreversible in the sense that N and N † mirror their dynamics only in space, but not in time. In this case, each attractor of N defines a unique arrow of time. A simple "time-reversal test" is given for testing whether an attractor of a CA rule is time-reversible or time-irreversible. For a time-reversible attractor of a CA rule N the past can be uniquely recovered from the future of N † , and vice versa. This remarkable property provides 170 concrete examples of CA time machines where time travel can be routinely achieved by merely hopping from one attractor to its bilateral twin attractor, and vice versa. Moreover, the time-reversal property of some local rules can be programmed to mimic the matter–antimatter "annihilation" or "pair-production" phenomenon from high-energy physics, as well as to mimic the "contraction" or "expansion" scenarios associated with the Big Bang from cosmology. Unlike the conventional laws of physics, which are based on a unique universe, most CA rules have multiple universes (i.e. attractors), each blessed with its own laws. Moreover, some CA rules are endowed with both time-reversible attractors and time-irreversible attractors. Using an analytical approach, the time-τ return map of each Bernoulli στ-shift attractor of all 112 Bernoulli rules are shown to obey an ultra-compact formula in closed form, namely,. [Formula: see text] or its inverse map. These maps completely characterize the time-asymptotic (steady state) behavior of the nonlinear dynamics on the attractors. In-depth analysis of all but 18 global equivalence classes of CA rules have been derived, along with their basins of attraction, which characterize their transient regimes. Above all, this paper provides a rigorous nonlinear dynamics foundation for a paradigm shift from an empirical-based approach à la Wolfram to an attractor-based analytical theory of cellular automata.
One carbon metabolism in anaerobic bacteria: Regulation of carbon and electron flow during organic acid production (1993)

The project deals with understanding the fundamental biochemical mechanisms that physiologically control and regulate carbon and electron flow in anaerobic chemosynthetic bacteria that couple metabolism of single carbon compounds and hydrogen to the production of organic acids (formic, acetic, butyric, and succinic) or methane. The authors compare the regulation of carbon dioxide and hydrogen metabolism by fermentation, enzyme, and electron carrier analysis using Butyribacterium methylotrophicum, Anaeroblospirillum succiniciproducens, Methanosarcina barkeri, and a newly isolated tri-culture composed of a syntrophic butyrate degrader strain IB, Methanosarcina mazei and Methanobacterium formicicum as model systems. To understand the regulation of hydrogen metabolism during butyrate production or acetate degradation, hydrogenase activity in B. methylotrophicum or M. barkeri is measured in relation to growth substrate and pH; hydrogenase is purified and characterized to investigate number of hydrogenases; their localization and functions; and, their sequences are determined. To understand the mechanism for catabolic CO{sub 2} fixation to succinate the PEP carboxykinase enzyme and gene of A. succiniciproducens are purified and characterized. Genetically engineered strains of Escherichia coli containing the phosphoenolpyruvate (PEP) carboxykinase gene are examined for their ability to produce succinate in high yield. To understand the mechanism of fatty acid degradation by syntrophic acetogens during mixed culture methanogenesis formate and hydrogen production are characterized by radio tracer studies. It is intended that these studies provide strategies to improve anaerobic fermentations used for the production of organic acids or methane and, new basic understanding on catabolic CO{sub 2} fixation mechanisms and on the function of hydrogenase in anaerobic bacteria.
Probabilistic motion planning for redundant robots along given end-effector paths (2003)

We consider the problem of planning collision-free motions for a redundant robot whose end-effector must travel along a given path. Although collision avoidance is one of the main reasons for introducing kinematic redundancy in manipulators, the planning methods so far proposed for this particular problem are neither efficient nor complete. In this paper, we introduce some algorithms that may be considered as an extension of probabilistic planning techniques to the problem at hand. All the algorithms are based on the same simple mechanism for generating random samples of the configuration space that are compatible with the end-effector path constraint. Experimental results illustrate the performance of the planners.
Mechanical Properties of Al-Cr Base Alloys Containing Icosahedral Phase Produced by Extrusion of Atomized Powder. (1997)

Bulk Al96-xCr3Ce1Cox(x=1, 1.5, 2) and Al95-x Cr3Ce1CoxTM1(TM=Zr, Mn, Fe) materials with a dimension of about φ8 mm×300 mm were produced by extrusion of gas atomized powders at 523, 573, 623, 673 and 723 K. The gas atomized powder has a spherical shape with an average diameter of about 15μm, which consists of icosahedral, Al, Al9Co2 and Al13Cr2 phases. The bulk Al94.5Cr3Ce1Co1.5 material extruded at 573 K consists of icosahedral, Al, Al9Co2 and Al13Cr2 phases. The Yong's modulus, Vickers hardness (Hv), ultimate tensile strength and plastic elongation in the bulk form are 83 GPa, 170, 570 MPa and 8.4 % for Al94.5Cr3Ce1Co15 and 89 GPa, 210, 670 MPa and 4.4 % for Al93.5Cr3Ce1Co1.5Mn1, respectively. The Hv at the testing temperature of 573 K for the Al94.5Cr3Ce1Co1.5 and Al92.5Cr3Ce1Co1.5Zr2 bulk materials are 55 and 75, respectively, which are more than twice as large as that for the 7075-T6 alloy.
The effect of intertrabecular fluid on femoral head mechanics. (1991)

The effect of intraosseous fluid on the mechanical characteristics of bone is unclear. To determine the potential effects of alteration in the fluid boundary conditions of the femoral head, a decompression procedure was performed. The stiffness of femoral heads from normal adult mongrel dogs was measured after the heads were subjected to a physiologic mechanical load. When the fluid boundary conditions were altered by drilling the femoral neck, femoral head stiffness was reduced by more than 30% (p = 0.045). Refilling of the femoral specimen with saline restored the stiffness to the baseline value. These observations demonstrate that in vitro changes of fluid boundary conditions can alter the mechanical integrity of the femoral head. Alteration in osseous fluid boundary conditions in vivo could affect joint integrity and be of pathogenetic significance in joint disease.

Custom-designed plaque radiotherapy is a potential treatment for selected patients with circumpapillary choroidal melanoma. We found satisfactory local tumor control, and globe retention was achieved in 75% of eyes with more than 5 months' follow-up.
Chromosomal Localization and Tissue Expression (1987)

The GPIIb-IIIa complex functions as a receptor for cytoadhesive proteins on the platelet surface. Both GPIIb and GPIIIa are synthesized by a human erythroleukemia (HEL) cell line. We isolated several cDNA clones by screening a HEL cell cDNA library with an oligonucleotide derived from amino acid sequence ofGPIIb. Nucleotide and amino acid sequences were determined from 703 bp of one of these clones. Amino acid sequence of purified platelet GPIIb peptides confirmed the identity ofthe clone. ThecDNA encodes the carboxyl terminus of the large (a) subunit of GPIIb and all of the smaller (f6) subunit of GPIIb. By hybridizing the cDNA directly to chromosomes separated by dual laser chromosome sorting, the gene for GPIIb was mapped to chromosome 17. Northern blot analysis showed a 3.4-kb GPIIb mRNA in HEL cells. We also compared the amino acid sequences determined from eight additional platelet GPIIb peptides with the derived amino acids from a published HEL cell GPIIb cDNA, and the platelet and HEL cell proteins appear to be the same. Despite previous reports that vascular endothelial cells and monocytes contain GPIIb, no GPIIbmRNA was observed in either type of cell. Thus, GPIIb appears to be specific for the platelet-megakaryocyte membrane and is distinct from the a subunits of the adhesion receptors in other normal tissues.
Improving perception of binocular stereo motion on 3D display devices (2014)

This paper investigates the presentation of moving stereo images on different display devices. We address three important issues. First, we propose temporal compensation for the Pulfrich effect when using anaglyph glasses. Second, we describe, how content-adaptive capture protocols can reduce false motion-in-depth sensation for time-multiplexing based displays. Third, we conclude with a recommendation how to improve rendering of synthetic stereo animations.
Limited Stress Response in <i>Streptococcus pneumoniae</i> (1999)

In Streptococcus pneumoniae, heat shock induces the synthesis of 65-, 73-, and 84-kDa proteins, and ethanol shock induces a 104-kDa protein. In this study, the 65-, 84-, and 104-kDa proteins were identified as members of the GroEL, ClpL and alcohol dehydrogenase families, respectively, and the general properties of the stress response of S. pneumoniae to several other stresses were characterized. However, several stresses which are known to induce stress responses in Escherichia coli and Bacillus subtilis failed to induce any high molecular weight heat-shock proteins (HSPs) such as GroEL and DnaK homologues. A minor temperature shift from 30 to 37 C triggered induction of the homologues of DnaK and GroEL of E. coli. These features may provide a foundation for evaluating the role of heat-shock proteins relative to the physiology and pathogenesis of pneumococcus.
