Dynamic Control of a Manipulator with Passive Joints in an Operational (1991)

In this paper, a method to control the tip position of a manipulator with passive joints, which have no actuators, in an operational coordinate space is presented. The equations of motion are described in terms of operational coordinates. The coordinates are separated into controlled coordinates and compensating coordinates. The accelerations of the controlled coordinates can be arbitrarily adjusted by using dynamic coupling of the manipulator. The effectiveness of the method is verified by experiments using a two-degree-of-freedom manipulator with a passive joint. The experiments show that the controlled coordinates of the position of the manipulator can be controlled precisely by use of the proposed method.
Flow Simulations on Cartesian Grids Involving Complex Moving Geometries (1999)

We describe a method to solve the compressible time-dependent Euler equations using Cartesian grids for domains involving fixed or moving geometries. We describe the concept of a mirror flow extrapolation of a given solution over a reflecting wall which may be curved or moving at a fixed or varying speed. We use this mirror flow to develop a Cartesian grid method to treat the cells along a reflecting boundary avoiding the “small-cell” problem. Numerical Results are presented.

The mass function of the stellar component of galaxies in the Sloan Digital Sky Survey (2004)

Using the MOPED algorithm, we determine non-parametrically the stellar mass function of 96 545 galaxies from the Sloan Digital Sky Survey Data Release One. By using the reconstructed spectrum due to starlight, we can eliminate contamination from either emission lines or active galactic nuclei components. Our results give excellent agreement with previous works, but extend their range by more than two decades in mass to 10 7.5 M s /h -2 M 10 12 . We present both a standard Schechter fit and a fit modified to include an extra, high-mass contribution, possibly from cluster central dominant galaxies. The Schechter fit parameters are = (7.8 0.1) 10 -3 h 3 Mpc -3 , M = (7.64 0.09) 10 10 h -2 M and = -1.159 0.008. Our sample also yields an estimate for the contribution from baryons in stars to the critical density of b * h = (2.39 0.08) 10 -3 , in good agreement with other indicators. Error bars are statistical and a Salpeter initial mass function is assumed throughout. We find no evolution of the mass function in the redshift range 0.05 < z < 0.34, indicating that almost all stars were already formed at z 0.34 with little or no star formation activity since then and that the evolution seen in the luminosity function must be largely due to stellar fading.
Identification of proteins associated with ligand‐activated estrogen receptor α in human breast cancer cell nuclei by tandem affinity purification and nano LC‐MS/MS (2010)

Estrogen receptor α (ER-α) is a key mediator of estrogen actions in breast cancer (BC) cells. Understanding the effects of ligand-activated ER-α in target cells requires identification of the molecular partners acting in concert with this nuclear receptor to transduce the hormonal signal. We applied tandem affinity purification (TAP), glycerol gradient centrifugation and MS analysis to isolate and identify proteins interacting with ligand-activated ER-α in MCF-7 cell nuclei. This led to the identification of 264 ER-associated proteins, whose functions highlight the hinge role of ER-α in the coordination of multiple hormone-regulated nuclear processes in BC cells.
Vaccination to treat persistent viral infection (2008)

Therapeutic vaccination is a potentially powerful strategy to establish immune control and eradicate persistent viral infections. Yet, despite numerous different approaches and for reasons that are unclear, vaccines administered during an established persistent viral infection fail to substantially elicit immunity or to control viral replication. Our hypothesis to explain this failure is that although vaccines are designed to stimulate T cells, they do not alleviate the immunosuppressive environment. As a result, vaccine‐activated T cells rapidly succumb to the same constraints that previously limited T cell responses during persistent infection. Using the lymphocytic choriomeningitis virus (LCMV) model of infection we found that the immunosuppressive environment (and not the vaccinating agent, level of virus replication or an inherent inability of exhausted T cells to respond to stimulation) is indeed responsible for the failure of therapeutic vaccines. Antibody blockade of the key suppressive factor interleukin‐10 rendered otherwise ineffective therapeutic vaccines highly efficient at restoring T cell immunity leading to immune‐mediated control of an established persistent viral infection. Thus, our findings help solve one of the great enigmas in infectious disease and vaccine design by demonstrating why therapeutic administration of a vaccine agent is unsuccessful whereas prophylactic administration of the same vaccine to pathogen naïve individuals (in which no immunosuppressive environment exists) is highly effective.
Evaluation of magnesium, calcium and aluminum metabolism in rats and monkeys maintained on calcium-deficient diets. (1991)

The epidemiology of amyotrophic lateral sclerosis (ALS) in the Western Pacific indicates that low concentrations of calcium (Ca) and magnesium (Mg) and high levels of aluminum (Al) in soil and water in these foci are etiologically important. To determine the biochemical derangements and metal deposition induced by chronic dietary deficiencies of Ca, we maintained experimental animals on several regimens. Male Wistar rats, weighing 100g, were fed either a standard diet, low Ca diet, low Ca-Mg diet, or low Ca-Mg diet with high Al for 90 days. Ca, Mg and Al content was determined in central nervous system (CNS) tissues and bone using inductively coupled plasma emission spectrometry (ICP). In separate studies, five male Japanese macaques (Macaca fuscata), weighing 3.5 to 5 kg, were fed alternately with diets, normal in Ca, low in Ca, low in Mg, low in Ca-Mg, or low in Ca-Mg with added Al for four-week periods. Serum Ca, Mg, Al, parathyroid hormone (PTH), bone Gla-protein (BGP) and alkaline phosphatase (ALP) were measured after feeding each dietary regimen. Ca and Mg levels in lumbar vertebrae and femur were significantly reduced and bone Al levels were significantly increased in rats fed diets deficient in Ca alone or diets low in Ca-Mg with or without added Al. Al content in bones was also higher in rats fed the Ca deficient diets. In monkeys fed the low Ca-Mg diet with added Al, reduced levels of serum Ca and Mg, serum PTH, BGP, and ALP were apparent. Our data support the conjecture that deranged bone mineralization induced by chronic dietary deficiency of Ca accelerates mobilization of Ca and Mg from bone and deposition in brain.
Optical System Design for Biosensors Based on CCD Detection (2009)

The use of Charge Coupled Device (CCD) detectors as an integral part of a biosensing system has become widespread in recent years due to several advantages of this type of detection, such as the ability to image multiple zones on the sensor, the flexibility of defining the sensing configuration and the low-noise performance of the detectors. The specification of the CCD as well as the selection of the other components in this system--including the source and the filters--is driven by the particular transduction mechanism, but all parts must be matched. Particular attention must be paid to reducing the various noise components of the CCD to obtain the lowest detection level, and it is shown that cooling the CCD is often a wise choice.
Cloning of a Cryptococcus neoformans gene, GPA1, encoding a G-protein alpha-subunit homolog (1994)

We have isolated a gene, GPA1, from Cryptococcus neoformans by the PCR technique. DNA sequencing of the GPA1 clone suggested that it encodes a protein homologous to the G-protein alpha-subunit family. Comparison of the deduced amino acid sequence of the GPA1-encoded protein revealed that it is about 45% identical to several mammalian Gi alpha subunits and 48% identical to the G alpha protein Gpa2 from Saccharomyces cerevisiae. G alpha proteins are known to be involved in mating of other yeasts, such as S. cerevisiae and Schizosaccharomyces pombe. Southern analysis demonstrated that GPA1 is present in a single copy within the Cryptococcus genome. Isolation of the cDNA for GPA1 confirmed that the gene contains six introns within the coding region. The GPA1 transcript was identified by Northern (RNA) analysis as a 1.6-kb RNA present in exponentially growing cells of both the alpha and a mating types. Moreover, the abundance of this transcript increased in cells shifted to starvation medium. Coincubation of alpha and a cells on starvation medium is required for mating of cryptococcal cells. Thus, our results are consistent with the involvement of C. neoformans GPA1 in mating.
Darwin Calibrator—Improving Project Productivity and Model Quality for Large Water Systems (2004)

This article discusses how optimization modeling provides engineers with a flexible and intelligent tool to achieve their water supply goals in the most cost‐effective manner. The article discusses a case study of using Haestad Methods' Darwin optimization technology to calibrate a water distribution model for the city of Guayaquil, Ecuador. The city hired Envirosoft and its local affiliated company Aquatec S.A. to develop an effective action plan for various tasks that included: an expansion program to manage installation of the required water and sewer connections; the design of new water and sewer networks; 30‐year master plans for the water, wastewater, and drainage systems; and, an action plan for the reduction of unaccounted‐for water. Envirosoft adopted WaterGEMS and Darwin software for hydraulic network simulation and optimization modeling. The goal of the project was to build an accurate hydraulic model of the water distribution network.
Context-independent phoneme recognition using a K-Nearest Neighbour classification approach (2009)

In this paper we investigate a non-parametric classification of English phonemes in speaker-independent continuous speech. We employ the ldquovotingrdquo k-nearest neighbour (k-NN) classifier, a powerful technique in pattern recognition problems, along with a new representation of phonemes for the speech recognition task. We also exploit the idea behind ldquoapproximaterdquo k-NN that results in a very fast way of computing the k approximate closest neighbours of each data point. Comparing the recognition performance of the proposed method with the HMM-based recognizer of HTK toolkit reveals that the k-NN-based recognizer outperforms its counterpart. In addition, incorporating the ldquoapproximaterdquo nearest neighbour search instead of the ldquoexactrdquo one results in completing the training step much faster than the HMM-based system, and the testing step with a comparable computational time. We also reduced the amount of the training data by applying a pattern recognition technique, called ldquothinningrdquo algorithm. The outcome was a considerable reduction in the k-NN search space and hence the execution time, and also a slight increase in the recognition performance.

MP49-07 THE RISK OF POSTOPERATIVE VENOUS THROMBOEMBOLISM ACCORDING TO THE CIRCULATING TUMOR CELL STATUS IN PATIENTS WITH UROTHELIAL CARCINOMA OF THE BLADDER TREATED WITH RADICAL CYSTECTOMY (2016)

groups according to CRP kinetics of the baseline nadir model. Patients whose pretreatment CRP levels were <5 mg/l; patients whose pretreatment CRP levels were >5 mg/l and normalized (<5 mg/l) at least one time during treatment; and patients whose pretreatment CRP levels were >5 mg/l and never normalized were assigned to the non-elevated, normalized and non-normalized CRP group, respectively. The prognostic impact of CRP kinetics was determined.
Cardiac contractility, central haemodynamics and blood pressure regulation during semistarvation (1991)

Eight obese patients were studied before and after 2 weeks of treatment by a very-low-calorie diet (VLCD). Cardiac output and central blood volume (pulmonary blood volume and left atrial volume) were determined by indicator dilution (125I-albumin) and radionuclide angiocardiography (first pass and equilibrium technique by [99Tcm]red blood cells). Cardiac output decreased concomitantly with the reduction in oxygen uptake as the calculated systemic arteriovenous difference of oxygen was unaltered. There were no significant decreases in left ventricular contractility indices, i.e. the ejection fraction, the peak ejection rate and changes in end-systolic volume. Also the diastolic function evaluated by the peak filling rate remained normal. Furthermore, no sign of backward failure could be demonstrated since the central blood volume was not significantly increased. Both systolic and diastolic blood pressure (BP) declined. The fall in BP was caused by the reduction in cardiac output as the total peripheral resistance was unchanged. Finally, the decline in total blood volume was not significant. These findings together with a reduction in heart rate indicated that a reduced sympathetic tone via increased capacitance of the venous bed was the main operator of a reduced venous return. Thus, the haemodynamic alterations in obese patients during short-term semistarvation may be caused by the fall in oxygen uptake and produced mainly by changes in the sympathetic tone.
100 Gb/s Optical DP-QPSK Using Two Surface Mount Dual Channel Modulator Drivers (2012)

A dual channel broadband surface mount optical modulator driver has been developed for use in 100Gb/s fiber optic transponders. Each channel is capable of delivering 4 to 8Vpp to each port of the optical modulator at data rates spanning through 43Gb/s with adjustable crossing point and eye quality control. This surface mount package solution enables a more compact system design and use of simple low cost surface mount assembly processes, eliminating the need for expensive connectorized driver and MUX module solutions and eliminating the need for expensive SMPM RF cable interconnects, which are key requirements for next generation 100Gb/s transponders.
An Experimental Study of the Forced Response of Pre- and Post-Critical Plates (1995)

Abstract Experimental results are presented which characterize the dynamic response of homogeneous, fully clamped, rectangular plates to narrow band acoustic excitation and uniform thermal loads. Using time series, pseudo-phase projections, power spectra and auto-correlation functions, small amplitude vibrations are considered about both the pre- and post-critical states. These techniques are then employed to investigate the snap-through response. The results for snap-through suggest that the motion is temporally complex and a Lyapunov exponent calculation confirms that the motion is chaotic. Finally, a snap-through boundary is mapped in the (ω, SPL) parameter space separating the regions of snap-through and no snap-through.
Serum angiotensin-converting enzyme levels in patients with recent-onset insulin-dependent diabetes after one year of low-dose cyclosporin therapy. IMDIAB Study Group. (1995)

Cyclosporin A (CyA) is today used for the treatment of autoimmune diseases and in the past was given also to patients with recent-onset insulin-dependent diabetes mellitus (IDDM). Hypertension is a major hazard in patients receiving CyA. In this study we have evaluated the effect of CyA administered to IDDM patients on blood pressure and serum angiotensin-converting enzyme (SACE), an endopeptidase that is an integral part of the renin-angiotensin and bradykinin systems. Sera from patients affected by recent-onset IDDM who were treated with CyA at the dose of 5 mg/kg body weight in addition to insulin therapy were included in the study (n = 13). Sera from 9 IDDM patients with the same clinical characteristics and followed up for 12 months represented the control group (insulin therapy only). SACE levels were measured at diagnosis and after 12 months. The results showed that SACE levels were elevated in IDDM patients at diagnosis and remained significantly high at 12 months in CyA-treated patients as compared to control patients (P < 0.006). Systolic and diastolic blood pressure were increased at 12 months in CyA-treated patients (p < 0.005 and p < 0.05, respectively). CyA therapy administered even at low doses to IDDM patients may increase SACE levels and also blood pressure. These findings should be considered when CyA is used for therapy of autoimmune diseases.
A fast leading eigenvector approximation for segmentation and grouping (2003)

We present a fast non-iterative method for approximating the leading eigenvector so as to render graph-spectral based grouping algorithms more efficient. The approximation is based on a linear perturbation analysis and applies to matrices that are non-sparse, non-negative and symmetric. For an N/spl times/N matrix, the approximation can be implemented with complexity as low as O(4N/sup 2/). We provide a performance analysis and demonstrate the usefulness of our method on image segmentation problems.
Photoluminescence studies of HgCdTe epilayers (2010)

Abstract Photoluminescence spectra on Hg 1‐x Cd x Te (x∼0.3) layers grown by molecular beam epitaxy on CdZnTe substrates were studied. The investigations were carried out on non intentionally doped, In doped and As doped samples and the effect of different annealing procedures were investigated. Excitation‐power dependent and temperature dependent comparative studies were performed. The transition mechanisms are discussed. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
