Optomechanical considerations for stable lasers (1991)

An analysis is presented that indicates the preferred optical arrangement for a stable laser oscillator is to use a hemispherical resonator. Qualitative observations suggest that laser frequency variation is independent of excitation position on the laser box structure. An excitation position that efficiently couples to the end plates on which mirrors are mounted produces substantially higher laser frequency variations.
Compositional shift in AlxGa1−xN beneath annealed metal contacts (2004)

Interfacial reactions between Ni, Pd, or Au contacts and AlxGa1−xN with compositions x=0.15 and 0.47 were studied in this investigation. X-ray photoelectron spectroscopy and scanning transmission electron microscopy coupled with energy dispersive spectroscopy showed that reaction between these metals and AlxGa1−xN results in a pronounced shift in the AlxGa1−xN beneath the contact to an Al-enriched composition. This Al enrichment results from the preferential outdiffusion of Ga into the metal films, and this reaction is consistent with thermodynamic driving forces in these systems. Possible consequences of the observed compositional shift on the electrical properties of contacts to AlxGa1−xN are also discussed.
High-resolution fibre-optic sensor for angular displacement measurements (2010)

The design of a fibre-optic sensor able to measure high-precision angular displacements is presented. The sensor has a small size which allows easy integration in miniature mechanical systems. Two configurations are designed: lens-free configuration and GRIN micro-lens configuration for which the micro-lens is fixed on the tip of the probe. The experimental results obtained by the angular displacement sensor based on the lens-free configuration are compared with the simulation results based on the modelling of the system and a good agreement is found. Then, a long-range measurement technique is described. In the 'lens-free and long-range configuration', the limit of resolution is measured (2 × 10−3°) or calculated (4.8 × 10−4°) over a range of [−23.4°, +23.4°]. In the 'GRIN lens and long-range configuration', the best limit of resolution is decreased to 2.2 × 10−4° but over a smaller range of [–14.5°, +14.5°]. Finally, the sensor in its 'lens-free configuration' design is integrated into a miniature electromagnetic actuator to determine its stroke by a comparison of the output signal obtained between this unknown-stroke actuator and a rotating stage for which the stroke was precisely known.
VC and ACIS/HOOPS based semi-physical virtual prototype design and motion simulation of 2D scanning mirror (2013)

Image-spectrum integrated instrument is an infrared scanning system which integrates optics, mechanics, electrics and information processing. Not only can it achieve scene imaging, but also it can detect, track and identify targets of interests in the scene through acquiring their spectra. After having a brief introduction to image-spectrum integrated instrument and analyzing how 2D scanning mirror works, this paper built 3D model of 2D scanning mirror and simulated its motion using two PCs basing on VC++ and ACIS/HOOPS. Two PCs communicate with each other through serial ports. One PC serves as host computer, on which controlling software runs, is responsible for loading image sequence, image processing, target detecting, and generating and sending motion commands to scanning mirror. The other serves as slave computer, on which scanning mirror motion simulation software runs, is responsible for receiving motion commands to control scanning mirror to finish corresponding movements. This method proposed in this paper adopted semi-physical virtual prototype technology and used real scene image sequence to control virtual 2D scanning mirror and simulates motion of real 2D scanning mirror. It has no need for real scanning mirror and is of important practical significance for debugging controlling software of 2D scanning mirror.
Optimization for Black-box Objective Functions (2003)

In many practical engineering design problems, the form of objective functions is not given explicitly in terms of design variables. Given the value of design variables, under this circumstance, the value of objective functions is obtained by real/computational experiments such as structural analysis, fluidmechanic analysis, thermodynamic analysis, and so on. Usually, these experiments are considerably expensive. In order to make the number of these experiments as few as possible, optimization is performed in parallel with predicting the form of objective functions. Response Surface Methods (RSM) are well known along this approach. This paper presents a brief review machine learning approaches to RSM such as Radial Basis Function Networks (RBFN) and Support Vector Machines (SVM). One of the most important tasks in this approach is to find effective sample data moderately in order to make the number of experiments as small as possible. Several methods are compared along with numerical examples.
Absorption effects in intermediate energy elastic electron scattering from xenon (2006)

We present experimental and theoretical differential cross sections for elastic electron scattering from xenon. Two independent measurements were carried out at (1) Chungnam National University for incident electron energies of 10, 20, 30, 50 and 100 eV and scattering angles from 10° up to 180° and (2) the Institute of Physics in Belgrade for incident electron energies of 20, 30 and 50 eV and scattering angles from 10° up to 150°. While these latter measurements do not cover the full angular range up to 180°, they still extend somewhat higher in scattering angle than previous measurements. It would appear that the theoretical treatment of intermediate energy elastic scattering from xenon is sensitive to the inclusion of absorption effects, particularly at backward scattering angles. This observation plus the previous results for the case of krypton indicates that the role of absorption is generally quite important for the rare gases.
Hydra: software for tailored processing of H/D exchange data from MS or tandem MS analyses (2009)

The customizable workflows and user-friendly interfaces of Hydra removes a significant bottleneck in processing and visualizing H/DX-MS data and helps the researcher spend more time executing new experiments and interpreting results. This increased efficiency will encourage the analysis of larger protein systems. The ability to accommodate the tandem MS dimension supports alternative data collection and analysis strategies, as well as higher resolution localization of deuteration where permitted by the fragmentation mechanism.
HYDRODYNAMIC COEFFICIENTS OF RECTANGULAR BARGES IN SHALLOW WATER (1979)

Forced oscillation tests in vertical and horizontal direction have been carried out with a 2 m model of a rectangular offshore pontoon and a cutter dredge pontoon in shallow water. Scale ratio 1:32.5. The water depths were 4.5, 1.75 and 1.2 times the draught of the model. the frequency ranged from 0.2 Hz up to 2.0Hz. All experimental results are presented in figures to show the influence of water depth, amplitude and frequency on added mass and damping. Order from NSFI as No. 19507.
A Class of Logistic Regression Models for Multivariate Binary Time Series (1989)

Abstract A logistic model for multivariate binary time series is proposed. First, we establish the equivalence between a log-linear model for the marginal distribution of a multivariate binary random vector and logistic models for the conditional distributions of each component given the others. The logistic formulation is used to describe a Markov chain for each series, which implies a Markov model for the vector of time series. A pseudolikelihood estimation procedure is presented. The methods are illustrated with data on psychosomatic and psychological diagnoses for families in a health-maintenance plan.
Natural Convection in the Horizontal Fluid Layer driven by Internal Heat Generation : 1. Stability Analysis (2002)

The natural convection induced by internal heating was studied. In order to clarify convective patterns in this phenomenon, we analyzed stability of fluid layers for various profiles of heat generation, H(z). As the result, the influence of the shape of the heat distribution upon the convective pattern was clarified.
Radioactive lysine in protein metabolism studies. Synthesis and utilization of plasma proteins (1950)

We have long been interested in protein metabolism, blood protein production and exchange, body protein needs as sustained by plasma protein or hemoglobin given parenterally and the labile exchange between reserve protein stores and circulating plasma proteins.This adds up to a dynamic equilibrium in body protein production, storage and utilization or exchange (9,21,22).The availability of synthetic DL-lysine-^ -C^ with C^ in unequivocally knovm position (13) has enabled us to study not only the incorporation of this essential amino acid in the various body proteins, but also to follow the time course of the isotopically labeled blood proteins.In addition, the apparent rate of disappearance of the labeled plasma proteins injected into normal recipient animals has been studied in an atten^t to define the comparative behavior of the plasma albumin and globulin fractions.It will be seen that in these experiments the globulin fraction is turned over more rapidly than the albumin fraction on a greim for gram basis.EIPERIMENTAL METHODS A description of dogs used in these experiments and their dietary histories, including the amounts of DL-lysine-^-C fed, is included in individual experimental histories below.Whenever the term specific activity Ih is used, it refers to the per cent administered C per gram carbon of the material under consideration.The DL-lysine-(-Cr^ was synthesized under the direction of Dr. R. W. Helmkamp and his collaborators in the Department of Organic Chemistry, The University of Rochester, according to their published method (13).The method of synthesis and the homogeneity of the labeled lysine on paper partition chromatography and subsequent autoradiography make the presence of significant amino acid or radioactive impurities very unlikely.AECO-490 1 ABCU-A90 For the quantitative collection of expired carbon dioxide, the dogs were placed in a sealed metal chamber of about 8 cu.ft. in volume.Fresh air was drawn from the outside through a flow meter at a rate of 130-140 cu.ft. per hour into the chamber by a continuously operated suction
Atypical lymphocytic lobular panniculitis: a clonal subcutaneous T‐cell dyscrasia (2008)

ALLP represents a form of cutaneous lymphoid dyscrasia given the relatively self-limited nature of the eruption, albeit in the context of clinical recurrence.
Measuring meat texture and understanding its structural basis (1991)

The flesh of animals, and especially the muscle tissue, is a highly nutritious food. There are many carnivores and omnivores that have evolved to hunt or scavenge and eat the flesh from other animals; however in this chapter I shall concentrate on the human consumption of meat in a modern context, and particularly on our understanding of its textural qualities. It is a reasonable assumption that, in prehistoric times, obtaining a sufficient supply was the overriding priority. When there was enough to eat, the wholesomeness of the meat (i.e. freedom from disease, parasites and bacteriological spoilage) was most probably the first aspect of choice. The practice of cooking of meat may have conceivably come about as a way of reducing the risk of eating infected or rotting meat. In some areas of the world today, being able to obtain or afford meat is still a problem for many people. In Western society the supply and the wholesomeness of the supply of meat is largely taken for granted (although recent worries about Salmonella, Listeria and bovine spongiform encephalopathy show that wholesomeness is still an overriding concern) and the eating quality of meat – its taste, juiciness and texture – becomes a great consideration.
Metabolism of cinnamic, <i>p</i>-coumaric, and ferulic acids by <i>Streptomyces setonii</i> (1983)

Streptomyces setonii strain 75Vi2 was grown at 45 degrees C in liquid media containing yeast extract and trans-cinnamic acid, p-coumaric acid, ferulic acid, or vanillin. Gas chromatography, thin-layer chromatography, and mass spectrometry showed that cinnamic acid was catabolized via benzaldehyde, benzoic acid, and catechol; p-coumaric acid was catabolized via p-hydroxybenzaldehyde, p-hydroxybenzoic acid, and protocatechuic acid; ferulic acid was catabolized via vanillin, vanillic acid, and protocatechuic acid. When vanillin was used as the initial growth substrate, it was catabolized via vanillic acid, guaiacol, and catechol. The inducible ring-cleavage dioxygenases catechol 1,2-dioxygenase and protocatechuate 3,4-dioxygenase were detected with an oxygen electrode in cell-free extracts of cultures grown in media with aromatic growth substrates and yeast extract.

Renal amyloidosis in related English foxhounds (1996)

Renal amyloidosis was diagnosed in six related English foxhounds from two separate hunting kennels. There was no apparent age or sex predilection. All the dogs had clinical and laboratory findings compatible with renal disease. The onset of clinical signs was acute in all cases with death or euthanasia in five of the six affected dogs occurring within one week of presentation. The remaining dog was treated with diuresis which produced a temporary improvement. Histological examination of renal tissue from affected dogs identified the presence of both glomerular and interstitial amyloid, which was confirmed by immunohistochemical staining to be of the reactive type (amyloid A). There were occasional sclerosed glomeruli or glomeruli with thickened Bowman's capsules, in addition to interstitial and periglomerular infiltration with a predominance of plasma cells and lymphocytes and secondary changes including tubular eosinophilic casts. Renal papillary necrosis was identified in three dogs. One hound had concurrent multicentric lymphoma. Pedigree analysis of the affected dogs revealed that four individuals shared a common great grandsire and that the same dog was the grandsire of a further case. Pedigree analysis of five additional dogs from one of the kennels, all of which had clinical signs of acute renal failure but from which renal tissue was not available, revealed a close relationship to those foxhounds with confirmed renal amyloidosis.
Innovative IPV From Attenuated Sabin Poliovirus Or Newly Designed Alternative Seed Strains (2012)

This article gives an overview of the patent literature related to innovative inactivated polio vaccine (i-IPV) based on using Sabin poliovirus strains and newly developed alternative recombinant poliovirus strains. This innovative approach for IPV manufacturing is considered to attribute to the requirement for affordable IPV in the post-polio-eradication era, which is on the horizon. Although IPV is a well-established vaccine, the number of patent applications in this field was seen to have significantly increased in the past decade. Currently, regular IPV appears to be too expensive for universal use. Future affordability may be achieved by using alternative cell lines, alternative virus seed strains, improved and optimized processes, dose sparing, or the use of adjuvants. A relatively short-term option to achieve cost-price reduction is to work on regular IPV, using wild-type poliovirus strains, or on Sabin-IPV, based on using attenuated poliovirus strains. This price reduction can be achieved by introducing efficiency in processing. There are also multiple opportunities to work on dose sparing, for example, by using adjuvants or fractional doses. Renewed interest in this field was clearly reflected in the number and diversity of patent applications. In a later stage, several innovative approaches may become even more attractive, for example the use of recombinant virus strains or even a totally synthetic vaccine. Currently, such work is mainly carried out by research institutes and universities and therefore clinical data are not available.
Soluble CD23 potentiates interleukin‐1‐induced secretion of interleukin‐6 and interleukin‐1 receptor antagonist by human monocytes (1994)

The low-affinity receptor for IgE (CD23) is cleaved into biologically active soluble fragments (sCD23), some of which have been reported to exhibit pleiotropic activities. However, it is not known whether the sCD23 fragments contribute to the induction and/or regulation of pro-inflammatory cytokine production. In this study, this possibility was tested using interleukin (IL)-1-stimulated human whole blood as an ex vivo model of cytokine cascade production. We show that human recombinant 25-kDa sCD23 significantly enhanced the production of IL-6 in whole blood stimulated by IL-1, but had only little or no effect in the absence of IL-1. The potentiating effect of sCD23 was concentration dependent within the range of plasma levels occurring during various inflammatory processes in man. These results prompted us to study whether sCD23 and IL-1 together also enhance the production of regulating factors exhibiting anti-cytokine activities. Our data indicate that sCD23 augments the release of IL-1 receptor antagonist induced by IL-1. Finally, examining the effect of sCD23 on human peripheral monocytes stimulated by IL-1, we confirmed the capacity of sCD23 to potentiate cytokine production. We suggest that sCD23 can modulate monocyte functions, thereby contributing to the amplification and regulation of immune and inflammatory processes.
Simultaneous determination of the compositions and thicknesses of a multilayer film using spectroreflectometry (1998)

In the growth of III–V epitaxial layers, spectroreflectometry is a fast, convenient method for measuring layer thickness. The experimentally measured optical thickness is the product of the composition-dependent refractive index and the layer thickness. In the past, the thickness of a ternary layer was uniquely determined by fixing the composition using photoluminescence or x-ray measurements. In this article, we show that the decoupling can be accomplished by measuring and fitting the spectroreflectance in a wavelength range where there is significant variation of the refractive index, for example, near the semiconductor band gap. The technique is demonstrated by the simultaneous measurement of the compositions and thicknesses of multilayered AlGaAs/GaAs films incorporating up to three different AlGaAs compositions.
Study of an axial-type fan design technique using an optimization method (2009)

A robust axial-type fan design technique is developed by using an optimization method based on the gradient method. A three-dimensional fan blade was initially designed by stacking several two-dimensional (2D) blade profiles along the spanwise direction. These 2D blade profiles were designed using the free-vortex method and profile parameters such as the incidence, deviation, camber, and so on. The initial fan blade adopts 13 design variables to improve the target value of the fan efficiency or the total pressure. These design variables are used to control the rotor and stator profile for obtaining a better target value. In this study, fan efficiency is chosen as a target objective variable to be maximized, and the total and static pressure on the design point are applied as constraints. These procedures are applied to the design of an axial-type fan that must operate at a mass flowrate of 8.37 kg/s with a minimum total pressure rise of 670 Pa. The optimized fan not only increases the efficiency by 2.9 per cent but also satisfies the required total and static pressure conditions compared with the initially designed fan performance. The optimized fan performance agrees with the experimental results; therefore, this fan design technique can be applied to improve the efficiency and the operating pressure of axial-type fans.
Die Splenoportografie in der Diagnostik der Splenomegalie (1958)

Auf Grund der Weltliteratur und eigener Erfahrungen werden splenoportografische Bilder der Splenomegalien beschrieben und die Splenomegalien in 4 Gruppen eingeteilt: Splenomegalie bei Systemerkrankung, bei extrahepatischer portaler Verschließung, bei Lebererkrankungen und Splenomegalie bei Tumoren und Traumen der Milz. Unter anderem ist auch das Bild eines unechten Verschlusses beschrieben und erklärt. Im Zusammenhang mit der Tatsache des häufigen Vorkommens einer leichten und palpatorisch nicht nachweisbaren Milzvergrößerung bei extrahepatischem portalem Verschluß, wurde auf einige Faktoren, die an dem Entstehen der Splenomegalie bei diesem Verschluß teilhaben, hingewiesen. Zum Abschluß ist die Möglichkeit und Bedeutung der Splenoportografie in dieser Indikation ausgewertet und die Notwendigkeit der Eingliederung der Skiaskopie und Skiagraphie unter Routine-Untersuchungsmethoden der Milz und die Notwendigkeit des Einreihens der Splenoportografie unter die Hauptmethoden in der Diagnostik der Splenomegalien betont.
