Control using power lines - a European view (1997)

Power line carrier systems, which have found applications in the USA as control data and information data networks, have also become very popular in Europe as an alternative control network for use in building, home and industrial automation applications. Several communication techniques have been developed in Europe which differ from the ones in the USA, mainly because of differing power line regulations. The article describes power line regulations, signalling techniques and problems with mains communication in Europe, and reviews commercially available power line transceivers and chip sets.

What distinguishes successful from unsuccessful tobacco smoking cessation? Data from a study of young adults (TEMPO) (2015)

Work and family circumstances, co-occurring substance use and psychological difficulties may influence smoking cessation in young adults. These characteristics should be considered by individual and collective interventions aiming to help young smokers quit successfully.
Ion-source and low-energy beam-transport issues for H/sup -/ accelerators (2003)

H/sup -/ ions are being used in high-energy accelerators and spallation neutron-sources because of the efficiency with which they can be converted into protons at high energy, a mechanism utilized in schemes that provide injection into a ring by means of charge. This paper discusses new trends and recent developments in the field of H/sup -/ plasma generators, extraction systems, and low-energy beam-transport (LEBT) systems, with emphasis on low-emittance systems delivering beams in the 50-mA range.
Solid state delay unit for a cardiac arrhythmia monitor (1979)

A cheap alternative to tape loop delays has been described which is easy to construct. Although the system described here is for an arrhythmia monitoring system, it can be simply adapted to any device requiring a signal delay. Using 1024 shift registers, a delay of 2 1/2 seconds with a 3 dB signal bandwidth well in excess of 100 Hz is obtained; in theory, this delay and bandwidth combination should be obtained using 512 bit shift registers which would considerably reduce the cost. Full details including a circuit diagram are available on request.

Apoptosis-inducing effect of cinobufacini, Bufo bufo gargarizans Cantor skin extract, on human hepatoma cell line BEL-7402. (2008)

Cinobufacini, a water-soluble preparation of Chinese medicine, is extracted from the skin of Bufo bufo gargarizans Cantor. The present study sought to investigate the effects of Cinobufacini on apoptosis of the hepatocellular carcinoma cell line BEL-7402. Cell viability was measured by methyl thiazolyl tetrazolium assay. Cell morphology was observed by Hoechst 33258 staining. Western blotting analysis was used to detect Bax and Bcl-2 expression. Results indicated that Cinobufacini inhibited the proliferation of BEL-7402 cells in a dose and time-dependent manner. Marked morphological changes indicative of apoptosis were observed after treatment with different concentrations of Cinobufacini. Western blot analysis showed that Bcl-2 expression was down-regulated while Bax expression was upregulated. Thus, Cinobufacini may have a significant apoptosis-inducing effect on BEL-7402 cells, and this could prove useful for further anti-cancer research.
Temporal Trajectory Aware Video Quality Measure (2009)

The measurement of video quality for lossy and low-bitrate network transmissions is a challenging topic. Especially, the temporal artifacts which are introduced by video transmission systems and their effects on the viewer's satisfaction have to be addressed. This paper focuses on a framework that adds a temporal distortion awareness to typical video quality measurement algorithms. A motion estimation is used to track image areas over time. Based on the motion vectors and the motion prediction error, the appearance of new image areas and the display time of objects is evaluated. Additionally, degradations which stick to moving objects can be judged more exactly. An implementation of this framework for multimedia sequences, e.g., QCIF, CIF, or VGA resolution, is presented in detail. It shows that the processing steps and the signal representations that are generated by the algorithm follow the reasoning of a human observer in a subjective experiment. The improvements that can be achieved with the newly proposed algorithm are demonstrated using the results of the Multimedia Phase I database of the Video Quality Experts Group.
Single Port Laparoscopic Cholecystectomy With the TriPort System: A Case Report (2008)

Single port access surgery may be the next generation of minimally invasive surgery. This study reports a recent experience with the TriPort system (trademark pending, Advanced Surgical Concepts, Wicklow, Ireland) to perform a laparoscopic cholecystectomy via a single peri-umbilical incision. To the authors' knowledge, this is one of the first cases of single port laparoscopic cholecystectomy ever performed with this device in the United States. Randomized studies to compare single port laparoscopic cholecystectomy with traditional laparoscopic cholecystectomy, with specific regard to postoperative pain scores, would be helpful in determining how much additional benefit, if any, there is to the patient.

The Verification of Breakage Possibility and Vibration Properties of Glass Insulators by the High-speed Railway Service (2009)

This paper has studied breakage possibility of glass insulators by resonance and accelerated deterioration through the comparison of the natural vibration and on site vibration. The natural frequencies of the strut tube glass insulator was measured within a range of less than 1kHz. In the on site vibration, the largest frequency that was imposed on strut tube glass insulators was 80Hz with 1.13g of vertical vibration in the viaduct section, the largest vertical vibration (0.38g) was detected at 103Hz in the open route section. When site vibration and natural vibration of strut tube glass insulators were compared in terms of characteristics, the resonance frequency was not the same. In both the viaduct and open route sections, it seems that the impact by vertical vibration in strut tube glass insulators is large. It's very unlikely that glass insulators were damaged by fatigue accumulation of vibration since the possibility of damage by resonance was very low in consideration of the characteristics of natural vibration and site vibration of glass insulators. In addition, no damage was detected in the accelerated deterioration test.
Studying Early Lethality of 45,XO (Turner's Syndrome) Embryos Using Human Embryonic Stem Cells (2009)

Turner's syndrome (caused by monosomy of chromosome X) is one of the most common chromosomal abnormalities in females. Although 3% of all pregnancies start with XO embryos, 99% of these pregnancies terminate spontaneously during the first trimester. The common genetic explanation for the early lethality of monosomy X embryos, as well as the phenotype of surviving individuals is haploinsufficiency of pseudoautosomal genes on the X chromosome. Another possible mechanism is null expression of imprinted genes on the X chromosome due to the loss of the expressed allele. In contrast to humans, XO mice are viable, and fertile. Thus, neither cells from patients nor mouse models can be used in order to study the cause of early lethality in XO embryos. Human embryonic stem cells (HESCs) can differentiate in culture into cells from the three embryonic germ layers as well as into extraembryonic cells. These cells have been shown to have great value in modeling human developmental genetic disorders. In order to study the reasons for the early lethality of 45,XO embryos we have isolated HESCs that have spontaneously lost one of their sex chromosomes. To examine the possibility that imprinted genes on the X chromosome play a role in the phenotype of XO embryos, we have identified genes that were no longer expressed in the mutant cells. None of these genes showed a monoallelic expression in XX cells, implying that imprinting is not playing a major role in the phenotype of XO embryos. To suggest an explanation for the embryonic lethality caused by monosomy X, we have differentiated the XO HESCs in vitro an in vivo. DNA microarray analysis of the differentiated cells enabled us to compare the expression of tissue specific genes in XO and XX cells. The tissue that showed the most significant differences between the clones was the placenta. Many placental genes are expressed at much higher levels in XX cells in compare to XO cells. Thus, we suggest that abnormal placental differentiation as a result of haploinsufficiency of X-linked pseudoautosomal genes causes the early lethality in XO human embryos.
General solution of a monopole loaded by a dielectric hemisphere for efficient computation (2000)

A simple result for the general solution of a monopole loaded by a dielectric hemisphere is presented. The result can be calculated without the need for any numerical integration and, thus, it is computationally very efficient. In addition, the result is very easy to implement and should be useful to the design engineer.

Double-blind multicentre study of the activity of S-adenosylmethionine in hip and knee osteoarthritis. (1985)

A randomized double-blind multicentre clinical trial was carried out to verify the effectiveness and tolerance of S-adenosylmethionine (SAMe) versus ibuprofen in 150 patients with hip and/or knee osteoarthritis. Both drugs were given orally 400 mg thrice daily for 30 days. SAMe exhibited a slightly more marked activity than the reference drug in the management of the various painful manifestations of the joint disease. Minor side-effects developed in five patients of SAMe group, and in 16 patients of ibuprofen group. No drop-outs occurred. No changes were observed in the routine laboratory tests.
Bioconversion of acid-hydrolyzed poplar hemicellulose to acetic acid byClostridium thermoaceticum (1991)

Clostridium thermoaceticum was used to ferment carbohydrate released from pretreated oat splet xylan and hemicellulose isolated from hybrid poplar. Hydrolysis with dilute sulfuric acid (2.5% (v/v) for oat spelt xylan and 4.0% (v/v) for poplar hemicellulose) at 100°C for 60 min was found to release the highest concentration of fermentable substrate.C. thermoaceticum, when grown in non-pH controlled batch culture at 55°C under a headspace of 100% CO2, typically produced 14gl−1 acetic acid during a 48 h fermentation in medium containing 2% xylose. In fed-batch fermentations this organism was able to produce 42gl−1 acetic acid after 116h when the concentration of xylose was maintained at approximately 2% and the pH was controlled at 7.0.
High-radix division and square-root with speculation (1994)

The speed of high-radix digit-recurrence dividers and square-root units is mainly determined by the complexity of the result-digit selection. We present a scheme in which a simpler function speculates the result digit, and, when this speculation is incorrect, a rollback or a partial advance is performed. This results in operations with a shorter cycle time and a variable number of cycles. The scheme can be used in separate division and square-root units, or in a combined one. Several designs were realized and compared in terms of execution time and area. The fastest unit considered is a radix-512 divider with a partial advance of six bits.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Extracting the Expected Path of Monetary Policy from Futures Rates (2002)

Federal funds and eurodollar futures contracts are among the most useful instruments for deriving expectations of the future path of monetary policy. However, reading policy expectations from those instruments is complicated by the presence of risk premia. This paper demonstrates how to extract the expected policy path under the assumption that risk premia are constant over time, and under a simple model that allows risk premia to vary. In the latter case, the risk premia are identified under the assumption that policy expectations level out after a long enough horizon. The results provide evidence that the risk premia on these futures contracts vary over time. The impact of this variation is fairly limited for futures contracts with short horizons, but it increases as the horizon of the contracts lengthens.

A Monoclonal Antibody Specific for Reovirus Outer-Capsid Protein ς3 Inhibits ς1-Mediated Hemagglutination by Steric Hindrance (2001)

Reovirus virions are nonenveloped icosahedral particles consisting of two concentric protein shells, termed outer capsid and core. Outer-capsid protein sigma1 is the viral attachment protein and binds carbohydrate molecules on the surface of host cells. Monoclonal antibody (MAb) 4F2, which is specific for outer-capsid protein sigma3, blocks the binding of sigma1 protein to sialic acid and inhibits reovirus-induced hemagglutination (HA). To determine whether MAb 4F2 inhibits HA by altering sigma1-sigma3 interactions or by steric hindrance, we analyzed the effect of 4F2 immunoglobulin G (IgG) and Fab fragments (Fabs) on HA induced by reovirus strain type 3 Dearing (T3D). The concentration of 4F2 IgG sufficient to inhibit T3D-induced HA was 12.5 microg per ml, whereas that of Fabs was >200 microg per ml. Dynamic light scattering analysis showed that at the concentration of IgG sufficient to inhibit HA, virion-antibody complexes were monodispersed and not aggregated. The affinity of 4F2 Fabs for T3D virions was only threefold less than that of intact IgG, which suggests that differences in HA inhibition titer exhibited by 4F2 IgG and Fabs are not attributable to differences in the affinity of these molecules for T3D virions. We used cryoelectron microscopy and three-dimensional image analysis to visualize T3D virions alone and in complex with either IgG or Fabs of MAb 4F2. IgG and Fabs bind the same site at the distal portion of sigma3, and binding of IgG and Fabs induces identical conformational changes in outer-capsid proteins sigma3 and mu1. These results suggest that MAb 4F2 inhibits reovirus binding to sialic acid by steric hindrance and provide insight into the conformational flexibility of reovirus outer-capsid proteins.
Antitumor Effect of Anthocyanin Fractions Extracted from Red Soybeans and Red Beans in vitro and in vivo (1997)

Many bioflavonoids extracted from petals of higher plants and from fruit rinds, as well as purified flavonoids, have been reported to have antitumor effects in vitro and in vivo. Bioflavonoids extracted from red soybeans are mostly cyanin conjugated with glucose and rhamnose, whereas bioflavonoids of red beans are cyanin conjugated with rhamnose as revealed by thin-layer chromatogram. Flavonoids extracted from red soybeans were effective in inhibiting the growth of HCT-15 cells in vitro. On the other hand, flavonoids from red beans were not effective, although their hydrolyzed sugar-free forms were growth inhibitory. Sugar-bonded bioflavonoids extracted from both red soybeans and red beans were effective in prolonging the survival of Balb/C mice bearing syngeneic tumor-Meth/A cells, when they were dissolved in drinking water and given at a dose of approximately 500 micrograms/mouse/day.
CD34+Thy-1+Lin-Stem Cells from Mobilized Peripheral Blood (1996)

Over the last ten years there has been increasing use of mobilized peripheral blood (MPB) progenitor cells as grafts for autologous transplantation. Among the cells comprising these MPB autografts is a subpopulation of CD34+Thy-1+Lineage (Lin)- cells, which is enriched for hematopoietic stem cell (HSC) activity. The percentage of CD34+ cells which express Thy-1 is higher in some samples of MPB than in bone marrow (BM). Using myeloid and erythroid cell depletion prior to high speed cell sorting, it is possible to purify sufficient numbers of CD34+Thy-1+Lin-HSCs from a MPB leukapheresis sample for use as an autograft. CD34+Thy-1+Lin-cells will potentially provide a tumor-depleted autograft for cancer patients. This HSC population is also being studied as a potential target for gene transfer for the treatment of patients with HIV, cancer and a variety of genetic disorders.

Technetium-99m HM-PAO stereoisomers as potential agents for imaging regional cerebral blood flow: human volunteer studies. (1986)

A total of nine normal volunteer subjects were studied with three forms of [99mTc] hexamethylpropyleneamineoxime (HM-PAO), a potential cerebral blood flow imaging agent. One, the d,l isomer, showed 4.1% uptake in the brain which remained constant over 8 hr. There was good differentiation between uptake in gray and white matter on tomographic slices. We propose that this agent may allow regional cerebral blood flow imaging to be performed on a routine basis.
Habitat use of lake trout (<i>Salvelinus namaycush</i>) following species introduction (2012)

Abstract – Although introductions of prey species have the potential to significantly alter habitat use by top predatory fish, this aspect has rarely been directly quantified. Introduction of yellow perch ( Perca flavescens ), a littoral–pelagic prey species, to a small boreal lake previously dominated by littoral cyprinids provided a unique opportunity to examine how a change in forage base influenced habitat use by the sole top predator, lake trout ( Salvelinus namaycush ). We monitored lake trout pelagic and spatial distribution using acoustic telemetry before (2001) and after (2008) the introduction of perch to determine whether habitat use reflected a deeper, offshore prey community. After accounting for differences in water temperature and dissolved oxygen concentrations between years and the inclusion of a control lake, our data suggest that lake trout habitat use changed after the introduction of yellow perch. Lake trout, on average, were 1.4 m deeper ( P < 0.01), reduced their use of littoral habitat by 55% ( P = 0.03) and experienced a 71% decrease in home range size ( P < 0.01), consistent with a greater offshore habitat overlap between predator and prey after the introduction of yellow perch. This study illustrates how introduced prey species may have a significant influence on habitat use by top predatory fish, while also showing the importance of using direct measurements to quantify behavioural changes.
Staffing a Call Center with Uncertain Arrival Rate and Absenteeism (2006)

This paper proposes simple methods for staffing a single‐class call center with uncertain arrival rate and uncertain staffing due to employee absenteeism. The arrival rate and the proportion of servers present are treated as random variables. The basic model is a multi‐server queue with customer abandonment, allowing non‐exponential service‐time and time‐to‐abandon distributions. The goal is to maximize the expected net return, given throughput benefit and server, customer‐abandonment and customer‐waiting costs, but attention is also given to the standard deviation of the return. The approach is to approximate the performance and the net return, conditional on the random model‐parameter vector, and then uncondition to get the desired results. Two recently‐developed approximations are used for the conditional performance measures: first, a deterministic fluid approximation and, second, a numerical algorithm based on a purely Markovian birth‐and‐death model, having state‐dependent death rates.
