Similarity scoring for recognizing repeated out-of-vocabulary words (2010)

We develop a similarity measure to detect repeatedly occurring Out-of-Vocabulary words (OOV), since these carry important information. Sub-word sequences in the recognition output from a hybrid word/sub-word recognizer are taken as detected OOVs and are aligned to each other with the help of an alignment error model. This model is able to deal with partial OOV detections and tries to reveal more complex word relations such as compound words. We apply the model to a selection of conversational phone calls to retrieve other examples of the same OOV, and to obtain a higher-level description of it such as being a derivation of a known word.
A chemists view: Metal oxides with adaptive structures for thermoelectric applications (2016)

Thermoelectric devices can help to tackle future challenges in the energy sector through the conversion of waste heat directly into usable electric energy. For a wide applicability low‐cost materials with reasonable thermoelectric performances and cost‐efficient preparation techniques are required. In this context metal oxides are an interesting class of materials because of their inherent high‐temperature stability and relative high sustainability. Their thermoelectric performance, however, needs to be improved for wide application. Compounds with adaptive structures are a very interesting class of materials. A slight reduction of early transition metal oxides generates electrons as charge carriers and crystallographic shear planes as structure motif. The crystallographic shear planes lead to a reduction of intrinsic thermal conductivity. At the same time, the electronic transport properties can be tuned by the degree of reduction. So far only a few transition metal oxides with adaptive structures have been investigated with respect to their thermoelectric properties, leaving much room for improvement. This review gives an overview of thermoelectric oxides, highlights the structural aspects of the crystallographic shear planes and the resulting thermoelectric properties.

Polycyclic <i>N</i>‐heterocyclic compounds. <b>51</b>. Synthesis of novel 12‐substituted 11,13,15‐triazasteroidal compounds and their inhibitory activity on platelet aggregation (1996)

Abstract Synthesis of 11‐substituted 1,2,4,5‐tetrahydrobenzo[ h ]imidazo[1,2‐ c ]quinazolines corresponding to 12‐substituted 11,13,15‐triazasteroid is described. Evaluation on inhibitory activity against collagen‐induced platelet aggregation of these compounds and their precursors was also investigated.
A Proton Pump ATPase with Testis-specific E1-Subunit Isoform Required for Acrosome Acidification (2002)

The vacuolar-type H(+)-ATPases (V-ATPases) are a family of multimeric proton pumps involved in a wide variety of physiological processes. We have identified two novel mouse genes, Atp6e1 and Atp6e2, encoding testis-specific (E1) and ubiquitous (E2) V-ATPase subunit E isoforms, respectively. The E1 transcript appears about 3 weeks after birth, corresponding to the start of meiosis, and is expressed specifically in round spermatids in seminiferous tubules. Immunohistochemistry with isoform-specific antibodies revealed that the V-ATPase with E1 and a2 isoforms is located specifically in developing acrosomes of spermatids and acrosomes in mature sperm. In contrast, the E2 isoform was expressed in all tissues examined and present in the perinuclear compartments of spermatocytes. The E1 isoform exhibits 70% identity with the E2, and both isoforms functionally complemented a null mutation of the yeast counterpart VMA4, indicating that they are bona fide V-ATPase subunits. The chimeric enzymes showed slightly lower K(m)(ATP) than yeast V-ATPase. Consistent with the temperature-sensitive growth of Deltavma4-expressing E1 isoform, vacuolar membrane vesicles exhibited temperature-sensitive coupling between ATP hydrolysis and proton transport. These results suggest that E1 isoform is essential for energy coupling involved in acidification of acrosome.

Dielectric functions and critical points of BexZn1−xTe alloys measured by spectroscopic ellipsometry (2002)

Using a rotating analyzer spectroscopic ellipsometer, we have investigated the complex dielectric function of a series of ternary BexZn1−xTe thin films in the energy range between 0.7 and 6.5 eV for alloy concentrations between x=0.0 and x=0.52. After determining the alloy concentrations using x-ray diffraction and photoluminescence techniques, a standard inversion technique was used to obtain the optical constants from the measured ellipsometric spectra. Analyzing the second derivative of both the real and the imaginary parts of the dielectric constant, we have deduced the critical point parameters corresponding to the electronic transitions in the Brillouin zone. We find that the energy of the critical points with respect to Be concentration does not show any bowing effects unlike many other II–VI semiconductor ternary alloys.

Tribological Characteristics of Single-phase AlMgB14 and Nanocomposite AlMgB14-TiB2 Superhard Coatings (2008)

This study investigated the friction and wear characteristics of AlMgB14 and AlMgB14-TiB2 superhard coatings, produced by pulse laser deposition (PLD) and physical vapor deposition (PVD), respectively. Tests were conducted under unidirectional and reciprocating sliding against AISI 52100 bearing steel in both dry and oil-lubricated conditions. The AlMgB14 coating exhibited an encouraging but short-lived low friction stage (u = 0.2) in dry sliding. The AlMgB14-TiB2 coating reduced the wear rates by one order of magnitude for itself and three orders of magnitude for the counterface compared with the uncoated M2 tool steel in dry sliding. This nanocomposite coating also demonstrated significant extension (>2.5X) of the low friction (non-scuffing) stage in a lubricant starvation sliding.
Numerical Investigation of Heat Transfer Effects in Microchannels Under H2 Boundary Condition (2010)

Study of fluid flow characteristics at microscale level is gaining importance with shrinking device sizes. Better understanding of fluid flow and heat transfer in microchannels will have important implications in biomedical industry, MEMS, electronic chip cooling, heat exchangers, and microfluidic devices. Also, due to short lengths employed in microchannels, entrance header effects can be significant and needs to be investigated. In this work, three dimensional model of microchannels, with aspect ratios (α = a/b) ranging from 0.1 to 10, are numerically simulated using CFD software, FLUENT. Heat transfer effects in the entrance region of microchannel are presented by plotting average Nusselt number as a function of non-dimensional thermal entrance length x*. The numerical simulations with both circumferential and axial uniform heat flux (H2) boundary conditions were performed for four wall, three wall and two wall cases. Large numerical data sets, generated in this work for rectangular cross sectional microchannels for three walls and two walls H2 boundary condition, can provide better understanding and insight into the transport processes in the microchannel.
Cryo-electron microscopy structure and potential enzymatic function of human six-transmembrane epithelial antigen of the prostate 1 (STEAP1) (2020)

Six-transmembrane epithelial antigen of the prostate 1 (STEAP1) is an integral membrane protein that is highly up-regulated on the cell surface of several human cancers, making it a promising therapeutic target to manage these diseases. It shares sequence homology with three enzymes (STEAP2-STEAP4) that catalyze the NADPH-dependent reduction of iron(III). However, STEAP1 lacks an intracellular NADPH-binding domain and does not exhibit cellular ferric reductase activity. Thus, both the molecular function of STEAP1 and its role in cancer progression remain elusive. Here, we present a ∼3.0-Å cryo-EM structure of trimeric human STEAP1 bound to three antigen-binding fragments (Fabs) of the clinically used antibody mAb120.545. The structure revealed that STEAP1 adopts a reductase-like conformation and interacts with the Fabs through its extracellular helices. Enzymatic assays in human cells revealed that STEAP1 promotes iron(III) reduction when fused to the intracellular NADPH-binding domain of its family member STEAP4, suggesting that STEAP1 functions as a ferric reductase in STEAP heterotrimers. Our work provides a foundation for deciphering the molecular mechanisms of STEAP1 and may be useful in the design of new therapeutic strategies to target STEAP1 in cancer.
Automatic built-in self-test insertion for high level circuit descriptions (2002)

Traditionally, BIST is inserted into a circuit after the logic has been designed. This paper presents a tool that inserts BIST into high-level circuit descriptions prior to logic synthesis. We also present a novel BIST strategy called time multiplexed BIST (TMB). TMB is a method of testing sequential circuits that dispenses with one of the disadvantages of scan based methods. Scan-based testing requires serial shifting that causes increased test application time. TMB provides a compromise between fully serial and fully parallel load of all memory elements of the design. Test time is decreased compared to scan-based methods because instead of having the test patterns fed in one bit per clock cycle, TMB loads several memory elements with pseudo-random patterns during each clock cycle. Both BIST with serial scan and fully parallel load of all memory elements are special cases of TMB.

Gigabit-per-second cryogenic optical link using optimized low-temperature AlGaAs-GaAs vertical-cavity surface-emitting lasers (1996)

We describe the design of GaAs-AlGaAs vertical-cavity surface-emitting lasers (VCSELs) that are optimized for operation at very low temperatures and the experimental demonstration of a free-space optical interconnect for cryogenic electronic systems using a VCSEL. We demonstrate high-speed modulation of the optical link at a data rate of up to 2 Gb/s at 77 K, with a very low bit-error rate of <10/sup -13/, and thermally stable operation is achieved over a wide range of cryogenic temperatures without laser bias current compensation. Cryogenic VCSELs with excellent lasing characteristics have been achieved over the entire temperature range from 150 K to 6 K, including high output power (22 mW), high power-conversion efficiency (32%), high slope efficiency (/spl sim/100%), low threshold voltage (1.75 V) and current (1.7 mA), as well as a high-modulation bandwidth (12 GHz) for a 16 /spl mu/m diameter device at 80 K.
Exploiting processor workload heterogeneity for reducing energy consumption in chip multiprocessors (2004)

Advances in semiconductor technology are enabling designs with several hundred million transistors. Since building sophisticated single processor based systems is a complex process from design, verification, and software development perspectives, the use of chip multiprocessing is inevitable in future microprocessors. In fact, the abundance of explicit loop-level parallelism in many embedded applications helps us identify chip multiprocessing as one of the most promising directions in designing systems for embedded applications. Another architectural trend that we observe in embedded systems, namely, multi-voltage processors, is driven by the need of reducing energy consumption during program execution. Practical implementations such as Transmeta's Crusoe and Intel's XScale tune processor voltage/frequency depending on current execution load. Considering these two trends, chip multiprocessing and voltage/frequency scaling, this paper presents an optimization strategy for an architecture that makes use of both chip parallelism and voltage scaling. In our proposal, the compiler takes advantage of heterogeneity in parallel execution between the loads of different processors and assigns different voltages/frequencies to different processors if doing so reduces energy consumption without increasing overall execution cycles significantly. Our experiments with a set of applications show that this optimization can bring large energy benefits without much performance loss.
An Analysis of Location of Needle Entry Point and Palpated PSIS in S1 Nerve Root Block (2010)

Fatty Acid Distribution in Triglycerides of Yeasts Grown on Glucose or n-Alkanes (1972)

SUMMARY Lipid contents of yeasts grown on glucose were: Candida lipolytica, 5·4%; C. tropicalis, 9·4%; C. utilis, 2·7%; Candida 107, 41%; Hansenula anomala, 12·5%; Rhodotorula glutinis, 2·7%; and R. graminis, 9·1%. In each yeast about 80% of the lipid consisted of triglycerides. When the triglycerides from five of the yeasts were analysed in detail, an unsaturated acid was invariably found at the 2-position. With Candida 107 and R. graminis about 50% of the total triglyceride fatty acids were saturated, resulting in over 50% of the triglycerides being of the 1,3-disaturated-2-monounsaturated type. When Candida 107 and C. tropicalis were grown on individual n-alkanes, from C12 to C16, the fatty-acid composition varied according to the chain length of the substrate, although with n-tridecane neither yeast produced tridecanoic acid in the triglycerideand with n-dodecane only C. tropicalis contained an appreciable amount of dodecanoic acid in the triglyceride (32% of the fatty acids). With both yeasts on each alkane substrate, the lipid contents were not only lower than when grown on glucose but contained a smaller proportion of triglyceride. Saturated acids were now located at the 2-position of the triglycerides: Candida 107 grown on n-tetradecane produced 46% of its triglycerides with a saturated acid at the 2-position. The main advantage to be gained by growing yeasts on n-alkanes is, as far as lipid formation is concerned, the biosynthesis of specific fatty acids rather than the production of plant-like triglycerides.
Phosphatidylcholine metabolism in neonatal mouse calvaria (1987)

Phosphatidylcholine metabolism was examined in neonatal mouse calvaria in vitro. Incorporation of choline into phosphatidylcholine was slow in this tissue. At 2 h after a pulse of [methyl-3H]choline only 30% of the tissue radioactivity was in the organic phase. Chromatography of the aqueous phase of the tissue extract revealed that more than half of the radioactivity was present as choline at this time. There was no accumulation of phosphocholine, which would have been expected if the cytidylyltransferase were the rate-limiting step in the CDP-choline pathway in the tissue. Choline kinase activity in calvarial cytosol was lower than choline kinase activity in liver cytosol of the same animals. No evidence for significant phosphatidylcholine synthesis through the methylation pathway was found in the calvarial tissue. Although rates of choline-phosphatidylcholine base exchange were higher in bone microsomes than in microsomes from liver, the rate of phosphatidylcholine production through this pathway appeared to be too slow to account for the phosphatidylcholine produced by the calvaria. Phosphatidylcholine synthesis in the calvaria was unaffected by 2 h of treatment with 10 nM-parathyroid hormone, 0.1 nM-0.1 microM-1 alpha,25-dihydroxycholecalciferol, 5 microM-prostaglandin E1 or 2.5 nM-salmon calcitonin, or by 17 h of treatment with 10 nM-parathyroid hormone or 0.1 nM-1 alpha,25-dihydroxycholecalciferol.
Graph cut with ordering constraints on labels and its applications (2008)

In the last decade, graph-cut optimization has been popular for a variety of pixel labeling problems. Typically graph-cut methods are used to incorporate a smoothness prior on a labeling. Recently several methods incorporated ordering constraints on labels for the application of object segmentation. An example of an ordering constraint is prohibiting a pixel with a ldquocar wheelrdquo label to be above a pixel with a ldquocar roofrdquo label. We observe that the commonly used graph-cut based alpha-expansion is more likely to get stuck in a local minimum when ordering constraints are used. For certain models with ordering constraints, we develop new graph-cut moves which we call order-preserving moves. Order-preserving moves act on all labels, unlike alpha-expansion. Although the global minimum is still not guaranteed, optimization with order-preserving moves performs significantly better than alpha-expansion. We evaluate order-preserving moves for the geometric class scene labeling (introduced by Hoiem et al.) where the goal is to assign each pixel a label such as ldquoskyrdquo, ldquogrounrdquo, etc., so ordering constraints arise naturally. In addition, we use order-preserving moves for certain simple shape priors in graphcut segmentation, which is a novel contribution in itself.
Analysis of the MSC(Multi-Spectral Camera) Operational Parameters (2002)

The MSC is a payload on the KOMPSAT-2 satellite to perform the earth remote sensing. The instrument images the earth using a push-broom motion with a swath width of 15 km and a GSD(Ground Sample Distance) of 1 m over the entire FOV(Field Of View) at altitude 685 km. The instrument is designed to haute an on-orbit operation duty cycle of 20% over the mission lifetime of 3 years with the functions of programmable gain/offset and on-board image data compression/storage. The MSC instrument has one channel for panchromatic imaging and four channel for multi-spectral imaging covering the spectral range from 450nm to 900nm using TDI(Time Belayed Integration) CCD(Charge Coupled Device) FPA(Focal Plane Assembly). The MSC hardware consists of three subsystem, EOS(Electro Optic camera Subsystem), PMU(Payload Management Unit) and PDTS(Payload Data Transmission Subsystem) and each subsystems are currently under development and will be integrated and verified through functional and space environment tests. Final verified MSC will be delivered to spacecraft bus for AIT(Assembly, Integration and Test) and then COMSAT-2 satellite will be launched after verification process through IST(Integrated Satellite Test). In this paper, the introduction of MSC, the configuration of MSC electronics including electrical interlace and design of CEU(Camera Electronic Unit) in EOS are described. MSC Operation parameters induced from the operation concept are discussed and analyzed to find the influence of system for on-orbit operation in future.
Quantum Antidot Formation and Correlation to Optical Shift of Gold Nanoparticles Embedded in MgO (2002)

Quantum antidots are subnanometer scale vacancy clusters, the localized electronic structure of which can significantly alter the properties of a nanomaterial. We use positron spectroscopy to study vacancy clusters generated during the formation of gold nanoparticles via ion implantation in an MgO matrix. We observed that quantum antidots are associated with the nanoparticle surfaces after annealing in an O2 atmosphere, but not after annealing in a H2 atmosphere. In the former case, the presence of quantum antidots bound to the gold nanoparticles correlates with the redshift of the gold surface plasmon resonance, thus allowing an explanation for the redshift based on the transfer of electrons away from the metal particles.
New Operational Matrices for Solving Fractional Differential Equations on the Half-Line (2015)

In this paper, the fractional-order generalized Laguerre operational matrices (FGLOM) of fractional derivatives and fractional integration are derived. These operational matrices are used together with spectral tau method for solving linear fractional differential equations (FDEs) of order ν (0 < ν < 1) on the half line. An upper bound of the absolute errors is obtained for the approximate and exact solutions. Fractional-order generalized Laguerre pseudo-spectral approximation is investigated for solving nonlinear initial value problem of fractional order ν. The extension of the fractional-order generalized Laguerre pseudo-spectral method is given to solve systems of FDEs. We present the advantages of using the spectral schemes based on fractional-order generalized Laguerre functions and compare them with other methods. Several numerical examples are implemented for FDEs and systems of FDEs including linear and nonlinear terms. We demonstrate the high accuracy and the efficiency of the proposed techniques.
