Neural network development for noise reduction in robust speech recognition (2003)

Speech recognition systems with small and medium vocabulary are used as natural human interfaces in a variety of applications. To make such a system more robust, the development of a neural network based noise reduction module is described. Using standard feedforward networks, several topologies have been tested to learn about the properties of neural noise reduction. For the development of a sufficiently robust nonadaptive system, information about the characteristics of the noise and speech components of the input signal including context information was taken into account. The focus is on the stepwise experiment-oriented improvement of a basic linear neural noise reduction network. The isolated word recognition system and the database used for the experiments are described. Results from different noise reduction networks are given. To test their robustness, simulations with varying input signal characteristics were made and are discussed. >
Lateral photoeffect in large area one-dimensional thin-film position-sensitive detectors based in <i>a</i>-Si:H <i>P</i>-<i>I</i>-<i>N</i> devices (1995)

The aim of this work is to provide the basis for the interpretation, under steady state conditions, of the lateral photoeffect in p-i-n a-Si:H one-dimensional thin-film position-sensitive detectors (1D TFPSD) and the determination of its linear spatial detection limits, function of the device, and light spot source characteristics. This leads to the development of a model, based on the application of the Poisson, continuity, and current density equations in the p-i-n junction, where two thin resistive layers, as equipotentials, are considered on both sides of the doped layers. The experimental data recorded in 1D TFPSD devices with different performances are compared with the predicted curves and the obtained correlations discussed.
Epitaxial Y-Ba-Cu-O films on Si with intermediate layer by rf magnetron sputtering (1988)

Epitaxial films of Y-Ba-Cu-O were obtained on a Si substrate, using an epitaxial intermediate layer consisting of BaTiO3(or SrTiO3)/MgAl2O4. MgAl2O4 was epitaxially grown on the Si(100) substrate by chemical vapor deposition. Then, SrTiO3 or BaTiO3 was also epitaxially grown on the MgAl2O4 layer by means of rf magnetron sputtering. Epitaxial Y-Ba-Cu-O films were prepared on BaTiO3(SrTiO3)/MgAl2O4/Si substrates by rf magnetron sputtering. Preparation of an Y-Ba-Cu-O film directly on MgAl2O4/Si was also studied, but only a randomly oriented polycrystalline film has been obtained so far. Resistive superconducting transitions with zero resistance at 65 K on SrTiO3/MgAl2O4/Si and at 70 K on BaTiO3/MgAl2O4/Si were observed.
Destruction of enteric bacteria and viruses during two-phase digestion (1989)

The pathogenic microorganism destruction obtained during two-phase anaerobic digestion was compared to that for a conventional single-stage digester using municipal wastewater treatment sludge. Operation was draw-and-fill. Total digester residence times of 10 days and 20 days were evaluated
A chronological database as backbone for clinical practice and research data management (2003)

To be widely accepted by physicians, computerized support systems for medical decision-making must be seamlessly integrated into the clinical workflow. These systems must present accurate information in a useable format to the right person at the right time. To build the large, clean, and reusable clinical databases needed for predictive modeling and for the coming wave of translational laboratory research, researchers and clinicians need more efficient medical database designs. We. developed a database organized chronologically as date-variable-value entries. By collecting complete disease and treatment history for patients, the database could serve both clinical and research needs. A prostate cancer database was prototyped in Microsoft Access and subsequently upsized to a SQL Server and ColdFusion web application; the system, an open source application, is now in use at Memorial Sloan-Kettering Cancer Center and at several outside institutions. The system has reduced the difficulty of data entry, eased error checking, and improved the flexibility, efficiency, and reproducibility of creating research datasets from raw data. For clinicians, the system improves efficiency chiefly by displaying a single screen intuitive summary of patient data and by reducing the need for dictation. Currently, we are working to expand the system to other forms of cancer, and to implement a physician. Tablet PC interface.
A highly sensitive microRNA biosensor based on ruthenium oxide nanoparticle-initiated polymerization of aniline (2010)

Well-defined voltammetric current peaks of polyaniline were observed at biosensors hybridized with ruthenium oxide nanoparticle-tagged microRNAs and incubated in a mixture of aniline/H(2)O(2), which can be used for direct microRNA expression profiling with excellent sensitivity.
Fusion of stereo and Lidar data for dense depth map computation (2017)

Creating a map is a necessity in a lot of robotic applications, and depth maps are a way to estimate the position of other objects or obstacles. In this paper, an algorithm to compute depth maps is proposed. It operates by fusing information from two types of sensor: a stereo camera, and a LIDAR scanner. The strategy is to estimate reliably the disparities of a sparse set of points, then a bilateral filter is used to interpolate the missing disparities. Finally, the interpolation is refined. Our method is tested on the KITTI dataset and is compared against several other methods which fuse those modalities, or are extended to perform this fusion. Those tests show that our method is competitive with other fusion methods.
A comparative study of dye prism ring lasers (1974)

The performance characteristics of several types of flashlamp- and N <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> -laser-pumped dye prism ring lasers have been investigated. A tuning range covering the whole visible spectrum was observed with bandwidths from 0.5 nm to 0.03 pm. Diffraction-limited output with power level up to 150 kW in multimode operation at high input energies and 2 kW in single-mode operation of the flashlamp-pumped version was obtained in the spectral range of rhodamine 6G.
Diamond films grown by hot filament chemical vapor deposition from a solid carbon source (1997)

Continuous diamond films have been grown on mirror-polished silicon, polycrystalline copper, SiC and high oriented pyrolytic graphite substrates using hot filament assisted chemical vapor deposition. Instead of using conventional gaseous carbon source, a graphite plate was used as the carbon source with hydrogen as the only feeding gas. No substrate pretreatment such as diamond powder scratching or negative biasing was needed. When carbon-13 was used as the carbon source, only diamond-12 was detected on carbon-13 indicating that deposition rather than direct conversion of carbon to diamond occurred. High nucleation density and conversion efficiency were obtained for the present growing process. Diamond films grown by this method were found to be particularly pure in diamond content.
Kosten sind nicht gleich Kosten! Über den Zusammenhang zwischen Gebührenautomatismus, Kostenexplosion und Akzeptanz (2009)

Das öffentlich-rechtliche Rundfunksystem steht derzeit (noch) ganz gut da. Die Kern-Zielgruppe des öffentlich-rechtlichen Fernsehens - Zuschauer im Durchschnittsalter "50 + x" - ist stabil. Das wird sich ändern. Trotz der demografischen Vergreisung werden jüngere Entscheider-Generationen nachwachsen: aktive Internetnutzer. TV spielt für sie keine Rolle mehr. Im Internet sind dem System aber die Hände gebunden. Ob die Jüngeren ständig steigende Rundfunkgebühren zu zahlen bereit sind, ist ebenfalls nicht sicher - die Akzeptanz ist gering. Die "Öffentlich-Rechtlichen" geben sich auch wenig transparent. Das hat seinen Grund: Über eigenes Missmanagement spricht man nicht gern, z.B. über die Pensionlasten - das Vollkaskosystem der (festen) Mitarbeiter. Tabuzonen, über die man nicht reden, schreiben, senden darf - Kritik ist nicht erwünscht, Diskussionskultur und Konfliktmanagement fehl am Platz.
Signatures: A language extension for improving type abstraction and subtype polymorphism in C++ (1995)

Abstract C++ uses inheritance as a substitute for subtype polymorphism. We give examples where this makes the type system too inflexible. We then describe a conservative language extension that allows a programmer to define an abstract type hierarchy independent of any implementation hierarchies, to retroactively abstract over an implementation, and to decouple subtyping from inheritance. This extension gives the user more of the flexibility of dynamic typing while retaining the efficiency and security of static typing. With default implementations and views flexible mechanisms are provided for implementing an abstract type by different concrete class types. We first show how the language extension can be implemented in a preprocessor to a C++ compiler, and then detail and analyse the efficiency of an implementation we directly incorporated in the GNU C++ compiler.
항정자항체가 체외수정 및 배아의 자궁내이식에 미치는 영향에 관한 연구 (1987)

난관의 원인으로 불임증이 확인된 25명을 대상으로 ELISA를 사용하여 항정자항체를 측정한 후 FSH/HMG로 과배란을 유도하였다. 과배란 유도 후 혈중 E2농도와 난포직경을 측정하고, 복강경으로 난자를 흡인한 후 체외수정 및 배아의 자궁내이식을 시행하여 항정자항체의 존재유무가 난소난포의 성장, 난할율 및 임신에 미치는 영향을 조사하여 다음과 같은 결론을 얻었다. 1. 인간난자의 체외수정 프로그램에 참여한 25명의 환자 중 항정자항체의 빈도는 28.0%(7명) 이었다. 2. 우성난포난소의 직경, 혈중 E2치, 난포의 분포, 흡인할 난포의 수 및 체취된 난자의 수, 난자의 성숙도 등은 항정자항체가 양성인 군과 음성인군 간에 차이가 없었다. 3. 항정자항체가 양성인 7명에서 30개의 배란직전의 성숙된 난자를 얻어 19개가 수정 후 44시간에 난할이 되어 63.3%의 난할율을 나타냈다. 항정자항체가 음성인 18명에서 60개의 배란직전의 성숙된 난자를 얻어 34개가 난할이 되어 난할율은 56.7%로서 양군간에 유의한 차이가 없었다. 4. 항정자항체가 양성인 7명중 1명에서 임신이 되어 임신 성공률은 14.3%이었고, 항정자항체음성인 18명 중 4명에서 임신이 되어 임신 성공률은 22.2%이었다. 이상의 결과는 혈중 항정자항체가 체외수정 후 난할율에 영향을 주지 않으며, 그 항체의 존재하에서도 임신성공이 가능하다는 것을 시사하고 있다.
Rat PPARs: Quantitative Analysis in Adult Rat Tissues and Regulation in Fasting and Refeeding (2001)

PPARs are members of the nuclear hormone receptor superfamily and are primarily involved in lipid metabolism. The expression patterns of all 3 PPAR isotypes in 22 adult rat organs were analyzed by a quantitative ribonuclease protection assay. The data obtained allowed comparison of the expression of each isotype to the others and provided new insight into the less studied PPAR beta (NR1C2) expression and function. This isotype shows a ubiquitous expression pattern and is the most abundant of the three PPARs in all analyzed tissues except adipose tissue. Its expression is especially high in the digestive tract, in addition to kidney, heart, diaphragm, and esophagus. After an overnight fast, PPAR beta mRNA levels are dramatically down-regulated in liver and kidney by up to 80% and are rapidly restored to control levels upon refeeding. This tight nutritional regulation is independent of the circulating glucocorticoid levels and the presence of PPAR alpha, whose activity is markedly up-regulated in the liver and small intestine during fasting. Finally, PPAR gamma 2 mRNA levels are decreased by 50% during fasting in both white and brown adipose tissue. In conclusion, fasting can strongly influence PPAR expression, but in only a few selected tissues.

Digital radiography image denoising using a generative adversarial network (2018)

Statistical noise may degrade the x-ray image quality of digital radiography (DR) system. This corruption can be alleviated by extending exposure time of detectors and increasing the intensity of radiation. However, in some instances, such as the security check and medical imaging examination, the system demands rapid and low-dose detection. In this study, we propose and test a generative adversarial network (GAN) based x-ray image denoising method. Images used in this study were acquired from a digital radiography (DR) imaging system. Promising results have been obtained in our experiments with x-ray images for the security check application. The Experiment results demonstrated that the proposed new image denoising method was able to effectively remove the statistical noise from x-ray images, while kept sharp edge and clear structure. Thus, comparing with the traditional convolutional neural network (CNN) based method, the proposed new method generates more plausible-looking images, which contains more details.
Preparation of poly(phenylene vinylene) from cycloalkylene sulfonium salt monomers and polymers (1988)

Abstract Two new types of p ‐xylene bis‐sulfonium chloride monomers were prepared from cycloalkylene sulfides. The polymerization characteristics of these monomers to form poly( p ‐xylene sulfonium chlorides), and the thermal elimination reactions of their polymers to poly( p ‐phenylene vinylene), were compared with those of two monomers prepared from dialkyl sulfides. The cycloalkylene sulfonium chloride monomer polymerized to higher yields and to higher molecular weight polymers, which showed more efficient elimination reactions.
Polymer track membranes as a trap support for reagent in fiber optic sensors (1996)

The article presents a new idea of the application of polymer track membranes (PTM) for immobilization of a reagent in fiber optic chemical sensors. PTM was made of a poly(ethylene terephthalate) foil (10 μm in thickness, pores of 0.2 μm in diameter). The usefulness of membranes additionally covered by poly(vinyl chloride) was tested in a fiber optic redox titrator. The titrator utilized N,N′-diphenylbenzidine as a reagent which changes its absorbance in dependence on the redox potential. The measuring system is based on a lightemitting diode and a silicon photodiode connected to a bifurcated fiber optic bundle. The gain is in price and availability of the membrane. © 1996 John Wiley & Sons, Inc.

Preparation and Adsorptive Properties of Membrane-Type Adsorbents for Lithium Recovery from Seawater (2002)

A membrane-type adsorbent of spinel-type manganese oxide was prepared by a solvent exchange method using poly(vinyl chloride) (PVC) as a binder. PVC was dissolved in N,N-dimethylformamide (DMF) solution, after which spinel-type lithium manganese oxide was mixed with the DMF solution. The suspension was spread into a thin film and immersed in water to solidify the PVC. The membrane was treated with an HCl solution to extract lithium, resulting in a membrane-type adsorbent. The preparation conditions were studied by changing the initial PVC concentration versus DMF and lithium manganese oxide content. The membrane thickness, manganese oxide content, and tensile and abrasion strengths were measured for each membrane. A new type of adsorption cell was designed for obtaining a parallel seawater flow along the membrane-type adsorbents. The lithium adsorption experiment was carried out using natural seawater at a linear velocity of 1.25 cm/min. Placing the membrane between spacers was found to be effective in raising the lithium adsorption rate. The adsorption rate depended on the preparation conditions. The membrane prepared from an initial PVC concentration of 8%, and a PVC additive content of 20% is optimum for the adsorption of lithium in seawater. The adsorbed lithium could be easily eluted by treating with an HCl solution.
Electrochemistry of Manganese Dioxide in Lithium Nonaqueous Cell: I . X‐Ray Diffractional Study on the Reduction of Electrolytic Manganese Dioxide (1989)

X‐ray diffractional (XRD) studies were carried out for the electrochemical reduction of heat‐treated electrolytic (250° and 400°C for 7 days). A series of XRD examinations indicated that the reaction proceeded without the destruction of the core structure of electrolytic manganese dioxide (EMD). The structural changes during the electrochemical reductions of both EMDs were described, assuming a tetragonal sublattice. Both heat‐treated electrolytic (HEMDs) behaved similarly in the tetragonal sublattice parameter vs. the reduction degree plots. During the first half of the reduction, HEMD phase having a tetragonal sublattice (, ) was converted into a new phase having an expanded tetragonal sublattice (, ), i.e., in a two‐phase reaction. In the 30–90% reduction, the a‐axis increased continuously as a function of reduction degree, i.e., in a homogeneous phase reaction. The possible crystal structure of the deep discharge product is discussed, assuming a tetragonal unit cell (,) having the structure by analogy with , and an orthorhombic unit cell, i.e., ,, . From these, assuming an orthorhombic unit cell having , , and , all diffraction lines from the reduction products of HEMD were indexed.
Preparation of transparent pea protein gels: a comparison of isolation procedures (1990)

Summary Two commercially viable procedures for the preparation of protein fractions from pea flour are described and discussed. These fractions form thermally induced transparent gels at acid pH and are composed of the globulins, vicilin and legumin, identified by electrophoresis and differential scanning calorimetry. The gels have clarities that allow their use as vegetarian substitutes for gelatin and additionally show thermal stabilities suitable for applications in hot products. The influence of other food ingredients (salt, sugar and vegetable oil) on gel clarity is also investigated.

Calibration of In-Phase/Quadrature Amplitude and Phase Response Imbalance for Coherent Receiver (2017)

Gene Expression Analysis of Host Innate Immune Responses during Lethal H5N1 Infection in Ferrets (2008)

How viral and host factors contribute to the severe pathogenicity of the H5N1 subtype of avian influenza virus infection in humans is poorly understood. We identified three clusters of differentially expressed innate immune response genes in lungs from H5N1 (A/Vietnam/1203/04) influenza virus-infected ferrets by oligonucleotide microarray analysis. Interferon response genes were more strongly expressed in H5N1-infected ferret lungs than in lungs from ferrets infected with the less pathogenic H3N2 subtype. In particular, robust CXCL10 gene expression in H5N1-infected ferrets led us to test the pathogenic role of signaling via CXCL10's cognate receptor, CXCR3, during H5N1 influenza virus infection. Treatment of H5N1-infected ferrets with the drug AMG487, a CXCR3 antagonist, resulted in a reduction of symptom severity and delayed mortality compared to vehicle treatment. We contend that unregulated host interferon responses are at least partially responsible for the severity of H5N1 infection and provide evidence that attenuating the CXCR3 signaling pathway improves the clinical course of H5N1 infection in ferrets.
Fabrication and evaluation of a 500 W cladding-light stripper (2013)

Fiber lasers have reached kW levels of output power. To achieve this level it is necessary to use reliable high-power components that sustain these power levels. Double-clad fibers (DCFs) are often used in high-power fiber lasers. Cladding-light strippers (CLSs) are used to remove unwanted light from the inner cladding of the DCF. This unwanted light consists of residual pump light or signal light that leaked into the cladding, thus requiring that the CLS removes both high-NA (>0.4) and low-NA (<0.1) light. Often high-index polymers are used to remove the unwanted light from DCFs<sup>1,2,3</sup>. Because the CLS has to be able to withstand several 100W and most polymers are not capable of exceeding temperatures more than 200°C, we investigated a CLS without polymers, based on an etching process. We present results from a CLS that was tested up to 500W of stripped power. We determined the angle dependency of the stripping efficiency by launching both high- and low-NA light into the fiber and evaluating the NA attenuation. Furthermore, we measured the dependency of the stripping efficiency on the length of the etched area and the etching time. With optimized parameters an attenuation of more than 20 dB when launching high-NA light and 6 dB with low-NA light was achieved. The CLS did not show any degradation in terms of attenuation or thermal behavior in a six-hour stability test.
Approximating digital 3D shapes by rational Gaussian surfaces (2003)

A method for approximating spherical topology digital shapes by rational Gaussian (RaG) surfaces is presented. Points in a shape are parametrized by approximating the shape with a triangular mesh, determining parameter coordinates at mesh vertices, and finding parameter coordinates at shape points from interpolation of parameter coordinates at mesh vertices. Knowing the locations and parameter coordinates of the shape points, the control points of a RaG surface are determined to approximate the shape with a required accuracy. The process starts from a small set of control points and gradually increases the control points until the error between the surface and the digital shape reduces to a required tolerance. Both triangulation and surface approximation proceed from coarse to fine. Therefore, the method is particularly suitable for multiresolution creation and transmission of digital shapes over the Internet. Application of the proposed method in editing of 3D shapes is demonstrated.
