The Pharmacotherapy of Obsessive-Compulsive Disorder (1993)

Potent inhibitors of 5-hydroxytryptamine (5-HT) reuptake have clearly been established as the first-line pharmacotherapy for treatment of obsessive-compulsive disorder (OCD). Although a variety of tricyclic antidepressants and monoamine oxidase inhibitors have similar efficacy in the treatment of depression and panic disorder, potent blockade of 5-HT transport appears to be a prerequisite for effective treatment of OCD. Adding agents that enhance 5-HT neurotransmission to ongoing treatment in patients whose OCD is refractory to 5-HT reuptake inhibitors has not yielded impressive results. However, the addition of low-dose dopamine (DA) antagonists to the regimens of treatment-resistant patients appears to be a potentially useful strategy for the specific subgroup of OCD patients with a comorbid chronic tic disorder such as Tourette's syndrome. Because of the toxicity associated with neuroleptics, a time-limited trial of those agents, with reassessment at regular intervals, is indicated. Pharmacologic studies suggest that both the 5-HT and DA systems may be critical to the treatment and possibly the pathophysiology of OCD.
Scattering of multi-Gaussian Schell-model beams on a random medium (2013)

Using the angular spectrum representation of plane waves, we investigate the scattering of multi-Gaussian Schell-model (MGSM) beams from a random medium within the accuracy of the first-order Born approximation. The far-zone properties, including the normalized spectral density and the spectral degree of coherence, are discussed. It is shown that the normalized spectral density and the spectral degree of coherence are influenced by the boundary of the beam profile (i.e., M), the transverse beam width, the correlation width of the source, and the properties of the scatterer.
A new low voltage precision CMOS current reference with no external components (2003)

A novel current reference with low temperature and supply sensitivity and without any external component has been developed in a 0.25 /spl mu/m mixed-mode process. The circuit is based on a bandgap reference (BGR) voltage and a CMOS circuit similar to a beta multiplier. An NMOS transistor in triode region has been used in place of a resistor in conventional beta multiplier to achieve a current which has a negative temperature coefficient and only oxide thickness dependent. The BGR voltage has a positive temperature coefficient to cancel the negative temperature coefficient of the beta multiplier. The simulation results using Bsim3v3 model show max-to-min fluctuation of less than 1% over a temperature range of -20/spl deg/C to +100/spl deg/C and a supply voltage range of 1.4 V to 3 V with /spl plusmn/30% tolerance for all of the used on- chip resistors. The maximum current variation is slightly less than the oxide thickness variation in the process corners.
Roles of P-Selectin in Inflammation, Neointimal Formation, and Vascular Remodeling in Balloon-Injured Rat Carotid Arteries (2000)

These results suggest that inhibition of P-selectin-mediated leukocyte recruitment prevents the development of neointimal formation, adventitial inflammation, and vascular shrinking and promotes pseudoendothelialization by luminal smooth muscle cells. This treatment thus beneficially affects vascular remodeling after balloon injury in rats.

Effect of pretreatment with the calcium antagonist nimodipine on local cerebral blood flow and histopathology after middle cerebral artery occlusion (1985)

We used the [14C]iodoantipyrine autoradiography technique to study the effect of pretreatment with the calcium antagonist nimodipine on local cerebral blood flow (lCBF) in rats that underwent middle cerebral artery (MCA) occlusion. In untreated control animals there were profound localized reductions in 1CBF 30 minutes after MCA occlusion. These were most pronounced in neocortical areas and in the caudate nucleus ipsilateral to the MCA occlusion. In animals pretreated with nimodipine (1 microgram X kg-1 X min-1 for 30 minutes before and 30 minutes after MCA occlusion), the ipsilateral decrease in 1CBF in cortical regions was significantly less than that in control animals. The drug did not appear to alter 1CBF in the ipsilateral caudate nucleus. Neuropathological quantification of the ischemic damage present 3 hours after occlusion showed that nimodipine pretreatment reduced the volume and extent of cellular damage in the periphery but not in the core of the lesion.
Transcatheter tricuspid valve intervention: state of the art (2017)

The assessment and management of tricuspid valve (TV) disease have evolved substantially in recent years. Increased understanding of the long-term adverse consequences of severe tricuspid regurgitation (TR), along with continued advances in surgical and percutaneous techniques, has led to a renewed interest in the "forgotten valve". The aim of this review is to explore the clinical and technical challenges related to transcatheter tricuspid valve treatment and to report the preliminary clinical experiences.
Comparison and evaluation of acceleration based step length estimators for handheld devices (2010)

A comparison between different step length estimation algorithms for pedestrian dead reckoning is presented. This work covers theoretic evaluation of the estimators' performance and presents a comparison based on measurement data. Measurement data were taken from a group of five adults walking at three different velocities. For reference, the sensors were placed according to the recommendation given for each algorithm. In respect to everyday usability the performance of the estimators is furthermore evaluated for arbitrary placement of the sensors, as it is the case when using a mobile measurement platform like a smartphone.
Photon counting pseudorandom noise code laser altimeters (2007)

We have characterized the performance of photon counting pseudorandom noise (PN) code laser ranging system at both 1064 and 1570 nm. The PN code modulation is a binary signal which is widely used in telecommunications and RF ranging applications. When used in lidar PN code modulation allows the transmitter to operate with a peak power, equal to only twice the average power which is compatible with the optical fiber communication technology. Our photon counting receiver approach accumulates the received photon stream into a histogram, then cross correlates the histogram with the original PN code sequence. The time of flight is given by the location of the peak in the correlation function. For multiple targets within the laser beam footprint, each target produce a peak in the correlation function at the delay corresponding to the target range. Our approach for altimetry also uses receiver range bin much shorter than the PN code bit period. This permits the correlation to be calculated with higher time resolution than the PN code bit period and substantially improves the time and range resolution. Our laboratory measurements with a breadboard receiver shows a greater than 90% probability of detection in a 0.5 msec integration time with 50 fW average received optical power at 1064 nm when using an InGaAsP hybrid photomultiplier tube detector. We have also achieved a less than 5cm rms ranging precision, when using a 250 psec range bin and at about 100 KHz detected signal photon rate.
<title>Aircraft engine blade cooling holes detection and classification from infrared images</title> (1999)

In order to inspect sets of cooling holes being properly drilled on an aircraft engine blade, a robotic controlled IR imaging system was designed. The system physically having a robot held the drilled blade at different viewing positions in front of an IR camera where a sequence of images were obtained for analysis and evaluation where a hot-air cool- air heating and cooling cycle was being administered at the base of the blade. An initial teach model was needed to enable the robot to remember the different viewing position of the blade in front of the camera so as to establish a position and orientation reference and sequence of cooling hole inspection. Two data processing algorithms had been achieved in this paper: 1) A position adjustment during the regular operation after the tach-mode so as to made sure that he cooling holes to be inspected matched the reference established by the teaching phase; 2) An image processing method to extract four meaningful features and to drive a pattern recognition system for the determination of cooling hole operating. Blade classification was based on the number of bad cooling holes as being good if all but one hole is determined to be good, unless the bad hole is positioned in one of four critical locations, in which case the blade was classified as bad. A hole is classified as being bad if the hole is blocked in some manner, or if the hole's diameter does not fall within a specified range. Two types of data which were considered to be significant in characterizing the hole were the temperature intensity of the hole as it was heated and cooled, and the change in the intensity as a function of time during the same period. Image data features for the holes were extracted from the images and applied to several classifiers to determine an optimal classification method. Different data sets and/or combinations of features for both training and testing sets were formed and tested. Over 90 percent performances were achieved under different evaluation methods.

A Spatial Spectral Scanning Technique for the Fabry–Perot Spectrometer (1965)

A technique is described whereby wavelength scanning of a Fabry–Perot spectrometer is accomplished by varying the angle at which light is transmitted through the etalon. It is in essence a simple photoelectric adaptation of the old photographic method but it has a number of important advantages. These are pointed out, and descriptions are given of four instruments in which the technique has been applied. One of these instruments is hypothetical, one is under construction, and two have been built and tested. They are all designed primarily for auroral and airglow observations, but the method should find use in studies where the source is either of low brightness or of short-lived duration. Because one can employ a solid etalon, the technique may also be useful in rocket and satellite instrumentation.
Random Genetic Simulation of the Internal Geometry of Deltaic Sand Bodies (1994)

Summary A new stochastic approach for modeling the internal geometry of deltaic sand bodies is presented that incorporates both genetic (or process-based) and geometric aspects. The genetic aspect takes geologic concepts into account, whereas the geometric aspect reduces the number of parameters for use in applications. Sand-body models resulting from this method honor the well data. This approach is applied to model the internal architecture of an Eocene deltaic sand-body outcropping near Roda, Spain. The simulations using a few wells are compared with the geologic reference model obtained using all the outcrop and log data. The sensitivity of the simulation results is also checked with respect to the fluctuation of the input parameters.
Catalytic One-Pot Production of Small Organics from Polysaccharides (2011)

The catalytic techniques that degrade polysaccharides such as cellulose and elaborate the resulting monomers into organic feedstocks in situ make up an old area of research that has been reignited of late. One-pot conversions of polysaccharides into small organic molecules under acidic, basic, oxidative, reductive and hydrothermal conditions have been reported, and a remarkable breadth of compounds have been produced. 5-Hydroxymethylfurfural (HMF), levulinic acid and polyols such as sorbitol have been obtained in particularly high yields, whereas serious selectivity struggles remain in reactions that produce organic acids such as lactic or glycolic acid. This review covers one-pot, catalytic transformations of polysaccharides into small organic molecules and focuses on mechanism, selectivity and optimization.
A comparison of preemptive and non-preemptive load distributing (2003)

The authors consider whether the addition of a migration facility to a distributed scheduler already capable of placement can significantly improve performance. They examine performance over a broad range of workload characteristics and file system structures. They find that while placement alone is capable of large improvement in performance, the addition of migration can achieve considerable additional improvement.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Free/total serum prostate‐specific antigen ratio: how helpful is it in detecting prostate cancer? (1998)

The f/t PSA ratio had no advantage over total PSA in improving specificity at a given sensitivity for detecting prostate cancer. Therefore, it cannot be recommended as a means of decreasing unnecessary biopsies in patients with a raised PSA level and/or an abnormal digital rectal examination. This applied particularly to the group of patients with a total PSA of 4-10 ng/mL.
Stochastic resonance: An approach for enhanced medical image processing (2007)

This paper presents a novel application of the stochastic resonance effect in medical image processing. Aiming to improve system performance, two noise modified image processing schemes are proposed. Performances of several medical image processing systems are shown to improve when suitable stochastic resonance noise is added.
Semantic Similarity in Biomedical Ontologies (2009)

In recent years, ontologies have become a mainstream topic in biomedical research. When biological entities are described using a common schema, such as an ontology, they can be compared by means of their annotations. This type of comparison is called semantic similarity, since it assesses the degree of relatedness between two entities by the similarity in meaning of their annotations. The application of semantic similarity to biomedical ontologies is recent; nevertheless, several studies have been published in the last few years describing and evaluating diverse approaches. Semantic similarity has become a valuable tool for validating the results drawn from biomedical studies such as gene clustering, gene expression data analysis, prediction and validation of molecular interactions, and disease gene prioritization. We review semantic similarity measures applied to biomedical ontologies and propose their classification according to the strategies they employ: node-based versus edge-based and pairwise versus groupwise. We also present comparative assessment studies and discuss the implications of their results. We survey the existing implementations of semantic similarity measures, and we describe examples of applications to biomedical research. This will clarify how biomedical researchers can benefit from semantic similarity measures and help them choose the approach most suitable for their studies.Biomedical ontologies are evolving toward increased coverage, formality, and integration, and their use for annotation is increasingly becoming a focus of both effort by biomedical experts and application of automated annotation procedures to create corpora of higher quality and completeness than are currently available. Given that semantic similarity measures are directly dependent on these evolutions, we can expect to see them gaining more relevance and even becoming as essential as sequence similarity is today in biomedical research.
Nonlinear light transfer in tunnel-coupled optical waveguides (1985)

It was confirmed experimentally for the first time that the distribution of high-intensity radiation between fiber-optic waveguides depends on the intensity of the radiation coupled into a waveguide. The nonlinear coefficient of the waveguides and the coefficient of the tunnel coupling between them were determined.
Effects of channel width and parasitic bipolar action on p-type poly-Si resistor characteristics (1991)

The effects of channel width on I-V characteristics of thin-film p-type poly-Si resistors are discussed, in particular for the case in which the resistor current is mainly due to field-enhanced generation of carriers at the drain end (as can be common at high drain electric field). A significant decrease in current per unit width (microamperes per micrometer) is observed as the channel width is reduced from 3 to 0.6 mu m. This decrease in current per unit width is due to the influence of fixed positive charge along the channel edges, which decreases the beta value associated with parasitic bipolar action in this regime of device operation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Development of a Species of Coprinus (1941)

SUMMARY(1) This paper describes the developmental morphology of a species of Coprinus close to, if not identical with C. cubensis. The organism was isolated from Costa Rican soil and is particularly adaptable for physiological study.(2) At the time of its isolation from natural conditions this organism will fruit in flask cultures on potato-dextrose agar in nine days under the proper environmental conditions.(3) Stages in the development of the fruit body are similar to those of other investigated species of the genus.(4) Examination of the buttons that would have produced typical sporophores reveals an annular prelamellar cavity and the lamellae of such buttons originate in the manner described by Atkinson for other Coprini.(5) Some of the buttons that never mature in agar cultures apparently do not form an annular prelamellar cavity and lamellae are not differentiated in the same manner as in the normal button. The writer believes that these are abnormalities which have resulted from the conditions that failed to bring about the production of normal sporophores.(6) The developmental study of this species indicates its close relationship to Coprinus tomentosus.

Measurement techniques to verify compliance with international telecommunication standards are also described.
Human amniotic mesenchymal stem cells to promote/suppress cancer: two sides of the same coin (2021)

Cancer is a leading cause of death in both developed and developing countries, and because of population growth and aging, it is a growing medical burden worldwide. With robust development in medicine, the use of stem cells has opened new treatment modalities in cancer therapy. In adult stem cells, mesenchymal stem cells (MSCs) are showing rising promise in cancer treatment due to their unique properties. Among different sources of MSCs, human amniotic fluid/membrane is an attractive and suitable reservoir. There are conflicting opinions about the role of human amniotic membrane/fluid mesenchymal stem cells (hAMSCS/hAFMSCs) in cancer, as some studies demonstrating the anticancer effects of these cells and others suggesting their progressive effects on cancer. This review focuses on recent findings about the role of hAMSCs/hAFMSCs in cancer treatment and summarizes the suppressing as well as promoting effects of these cells on cancer progression and underling mechanisms.
Schwebende Tröpfchen: Levitation in Ultraschallfeldern (2001)

Der gegebene Überblick über die Grundlagen und Anwendungen stehender Ultraschallfelder zur Positionierung fester, flüssiger und gasförmiger Proben in der Gasphase mag die Bedeutung dieser Technik veranschaulicht haben. Ausgehend von dem Phänomen der Positionierung von flüssigen und festen Proben bis hin zu den zum Teil noch offenen Fragen der Erforschung der Kaltgasfallen sowie der akustischen Agglomeration in stehenden Ultraschallfeldern eröffnet die Ultraschalllevitation ein weites und faszinierendes Forschungs- und Anwendungsgebiet.
