Performance of growing lambs fed grass silage with raw or extruded soybean or canola seeds (1997)

Thirty-two Outaouais male lambs were assigned to a completely randomized design with a 2 × 2 factorial arrangement of treatments to determine the effect of extrusion of full fat seeds on performance and carcass quality. Raw (NE) and extruded (EX) isonitrogenous and isoenergetic mixtures of barley and either full fat soybean (SB) or canola seed (CA) were fed at a daily rate of 424 and 400 g, respectively. Lambs were fed silage ad libitum from 20 to 43 kg. Intakes of silage DM and total DE were similar among treatments. The ADG and concentration of total polyunsaturated fatty acids (FA) in muscle were higher for lambs fed EX than NE seeds and the effect was greater for SB than CA mixture; this tended (P = 0.06) to result in an interaction between seed and extrusion for polyunsaturated FA in muscle. Similar trends were observed for feed efficiency. This could reflect the response to heat treatment as extrusion significantly reduced N degradability of SB mixture but had no effect on that of CA mixture. Digestibilities of DM, N, and energy were higher (P < 0.10) for lambs fed SB than for lambs fed CA mixture and extrusion had no effect. Data suggest that extrusion of seeds can be used to improve performance of lambs fed a high forage diet and modify FA composition of the carcass. Key words: Sheep, canola, soybean, carcass, extrusion
Context awareness for group interaction support (2004)

In this paper, we present an implemented system for supporting group interaction in mobile distributed computing environments. First, an introduction to context computing and a motivation for using contextual information to facilitate group interaction is given. We then present the architecture of our system, which consists of two parts: a subsystem for location sensing that acquires information about the location of users as well as spatial proximities between them, and one for the actual context-aware application, which provides services for group interaction.
Genital papillomavirus infection and cervical dysplasia—opportunistic complications of hiv infection (1992)

Certain human genital papillomaviruses (HPV) are strongly associated with cervical dysplasia and cancer. Evidence is accumulating that HPV infection and ano-genital cancers are more common in patients with the acquired immunodeficiency syndrome. The objective of our study was to evaluate the extent to which HPV infection and associated cervical disease constitute opportunistic complications of human immunodeficiency virus (HIV) infection in a population of sexually promiscuous, HIV-infected women in Kinshasa, Zaire. In 1989 we obtained Pap smears and cervicovaginal lavage specimens for HPV DNA testing from 47 HIV-seropositive and 48 HIV-seronegative prostitutes who were part of a cohort under observation since 1988. Thirty-eight percent of the HIV-seropositive and 8% of the seronegative women (odds ratio = 6.8; p = 0.001) had HPV DNA detected by either ViraType, a dot-blot assay which detects specific genital HPV types, or low-stringency Southern blot, which detects all HPV types. Eighty-two women (86%) had an interpretable Pap smear; 11 of 41 (27%) HIV-seropositive women and one of 41 (3%) seronegative women had cervical intra-epithelial neoplasia (CIN) (odds ratio = 14.7; p = 0.002). HIV seropositivity, HPV infection and CIN were highly associated. Eight (73%) of 11 seropositive women with CIN had HPV detected. Both HPV infection and cervical cancer may emerge as opportunistic complications of HIV infection in populations in which HIV, HPV and cervical cancer are common.
Denoising without access to clean data using a partitioned autoencoder (2015)

Training a denoising autoencoder neural network requires access to truly clean data, a requirement which is often impractical. To remedy this, we introduce a method to train an autoencoder using only noisy data, having examples with and without the signal class of interest. The autoencoder learns a partitioned representation of signal and noise, learning to reconstruct each separately. We illustrate the method by denoising birdsong audio (available abundantly in uncontrolled noisy datasets) using a convolutional autoencoder.
THE EFFECTS OF STRESSFUL LIFE EVENTS ON DEPRESSION (1997)

This chapter reviews recent research on the relationship between stressful life experiences and depression. A distinction is made between aggregate studies of overall stress effects and focused studies of particular events and difficulties. A distinction is also made between effects of life stress on first onset of depression and on the subsequent course of depression. Although the available evidence suggests that acute stressful life events can lead to the recurrence of episodes of major depression, a series of methodological problems compromise our ability to make clear causal inferences about the effects of life events on first onset of major depression or about the effects of chronic stress on either onset or recurrence of depression. The main problems of this sort are discussed, and recommendations made for ways of addressing these problems in future studies.

Ca<sup>2+</sup>‐dependent generation of mitochondrial reactive oxygen species serves as a signal for poly(ADP‐ribose) polymerase‐1 activation during glutamate excitotoxicity (2007)

Mitochondrial Ca(2+) uptake and poly(ADP-ribose) polymerase-1 (PARP-1) activation are both required for glutamate-induced excitotoxic neuronal death. Since activation of the glutamate receptors can induce increased levels of reactive oxygen species (ROS), we investigated the relationship of mitochondrial Ca(2+) uptake and ROS generation, and the possibility that ROS increase is a required signal for PARP-1 activation in cultured striatal neurons. Based on the spatial profile of NMDA-induced ROS generation, we found that only mitochondria showed a significant ROS increase within 30 min after NMDA receptor activation. This ROS increase was inhibited by the mitochondrial complex inhibitors rotenone and oligomycin, but not by the cytosolic phospholipase A(2) or xanthine oxidase inhibitors. Mitochondrial ROS generation was also inhibited by both removal of Ca(2+) from extracellular medium and blockage of mitochondrial Ca(2+) uptake by either a mitochondrial uncoupler or a Ca(2+) uniporter inhibitor. Furthermore, both DNA damage and PARP-1 activation induced by NMDA treatment was inhibited by blocking mitochondrial Ca(2+) uptake or by antioxidants. Our results demonstrate that ROS production during the early stage of acute excitotoxicity derives primarily from mitochondria and is Ca(2+)-dependent. More importantly, the increase of mitochondrial ROS serves as a signal for PARP-1 activation, suggesting that concomitant mitochondrial Ca(2+) uptake and PARP-1 activation constitute a unified mechanism for excitotoxic neuronal death.
A Contamination-Free Ultrahigh Precision Formation Flying Method for Micro-, Nano-, and Pico-Satellites with Nanometer Accuracy (2006)

Formation flying of clusters of micro‐, nano‐ and pico‐satellites has been recognized to be more affordable, robust and versatile than building a large monolithic satellite in implementing next generation space missions requiring large apertures or large sample collection areas and sophisticated earth imaging/monitoring. We propose a propellant free, thus contamination free, method that enables ultrahigh precision satellite formation flying with intersatellite distance accuracy of nm (10−9 m) at maximum estimated distances in the order of tens of km. The method is based on ultrahigh precision CW intracavity photon thrusters and tethers. The pushing‐out force of the intracavity photon thruster and the pulling‐in force of the tether tension between satellites form the basic force structure to stabilize crystalline‐like structures of satellites and/or spacecrafts with a relative distance accuracy better than nm. The thrust of the photons can be amplified by up to tens of thousand times by bouncing them between two mirrors located separately on pairing satellites. For example, a 10 W photon thruster, suitable for micro‐satellite applications, is theoretically capable of providing thrusts up to mN, and its weight and power consumption are estimated to be several kgs and tens of W, respectively. The dual usage of photon thruster as a precision laser source for the interferometric ranging system further simplifies the system architecture and minimizes the weight and power consumption. The present method does not require propellant, thus provides significant propulsion system mass savings, and is free from propellant exhaust contamination, ideal for missions that require large apertures composed of highly sensitive sensors. The system can be readily scaled down for the nano‐ and pico‐satellite applications.
TCF and Groucho-Related Genes Influence Pituitary Growth and Development (2003)

Mutations in the prophet of PIT1 gene (PROP1) are the most common cause of multiple pituitary hormone deficiency in humans; however, the mechanism of PROP1 action is not well understood. We report that Prop1 is essential for dorsally restricted expression of a Groucho-related gene, transducin-like enhancer of split 3 (Tle3), which encodes a transcriptional corepressor. Deficiency of a related gene, amino terminal enhancer of split (Aes), causes pituitary anomalies and growth insufficiency. TLE3 and AES have been shown to interact with TCF/LEF (transcripiton factors of the T cell-specific and lymphoid enhancer specific group) family members in cell culture systems. In the absence of TCF4 (Tcf7L2), Prop1 levels are elevated, pituitary hyperplasia ensues and palate closure is abnormal. Thus, we demonstrate that Tcf4 and Aes influence pituitary growth and development, and place Tcf4 and Tle3 in the genetic hierarchy with Prop1.
A high voltage, high current light-activated thyristor with a new light sensitive structure (1981)

To improve performance of a light-activated thyristor, its light sensitivity and dv/dt-capability were optimized by developing a novel structure of light sensistive area composed of a grooved light-incident region, n-emitter stripes and a new n-emitter shunt area. This shunt area is a by-pass of the dv/dt-induced displacement current. The relation between light-sensitivity and dv/dt-capability was studied on the basis of a quasi one-dimensional model. Applying this model for designing the structure of the light sensitive area, we developed a 4kV, 1200A light-activated thyristor composed of a tablet of 64mm diameter. This thyristor has a short turn-on delay time of 3 μsec at an incident light power of 5 mW and a high dv/dt-capability of 2000 V/μsec at a junction temperature of 125°C.
EFFECT OF RATE OF SEEDING UPON COMPARISON OF VARIETIES OF OATS (1932)

Three varieties of oats: Abundance, Banner and Daubeney, were sown at various rates in 1924-25-26 at four places differing widely in soil and climate, viz., Charlottetown, P.E.I., Macdonald College, Que., Scott, Sask., and Edmonton, Alberta. Daubeney has smaller seed and tillers more freely than the other two varieties.The method of field experimentation adopted is considered in the light of the principles of "randomisation" and "local control" developed at Rothamsted by R. A. Fisher. The plots sown at each rate were adequately replicated but their systematic arrangement precluded a valid estimate of the errors in yield comparisons. In particular, the arrangement of the plots sown at different rates was shown to coincide to some extent with variations in soil fertility.In general the differences in yield between plots of the same variety sown at different rates were small. Daubeney showed the greatest variations; the expected stabilizing effect of its tendency to tiller did not appear.The combined results of the three years indicate that the optimum rate of seeding may not be the same for different varieties at the same station, and certainly is not the same for the same variety at different stations. Near the optimum the effect of variations in seed rate upon yield were slight and, at three out of the four stations, all three varieties might be sown at a specified uniform rate without significantly increasing the ordinary experimental error.Large fluctuations were found in the percentage stand of plants recorded, due in part to unavoidable errors in counting, but still indicating significant differences between the stations. At three stations the optimum stand of Daubeney may have been higher than that of the other two varieties, though at only one station is the difference significant.
Air-powered sensor (2003)

This paper describes an application for powering wireless sensors. We use air motion to drive a miniature wind turbine. The intent is to use the device indoors, in air ducts used for heating, ventilating, and air-conditioning. We used commercially available off the shelf components for the airflow turbine. A low-speed, three-phase, brushless DC servomotor was used for the generator. A three-phase bridge constructed from six diodes was used to convert the AC current from the motor to DC current required by lowpower sensors. We used a four-inch fan blade for the turbine blade. We conducted a set of tests on the airflow turbine using resistive loads to demonstrate its energy conversion potential. We also showed that it could power a wireless sensor continually.
Writing performance of narrow trackwidth single pole perpendicular heads (2000)

The writing performance of narrow trackwidth single pole heads was studied on double layer perpendicular media. The main pole of the head was made of high moment Fe–Si–N laminated with Si–N. The narrow poles were made by trimming the wide main pole with an FIB milling system. Saturation recording was achieved by a 0.3 μm trackwidth head for media composed of a Co/Pd or Co–Cr–Nb–Pt recording layer and a Ni–Fe–Nb soft magnetic backlayer. With this head, clear recorded patterns were obtained. It was found that the number of reversed magnetic domains decreased remarkably as the trackwidth was reduced. The MFM images of 0.14 μm trackwidth recording at 400 kFRPI reveals a potential for recording densities exceeding 50 Gbit/in.2
Operating system support for mobile agents (2002)

The TACOMA project is concerned with implementing operating system support for agents, processes that migrate through a network. Two TACOMA prototypes have been completed; this paper outlines our experiences in building and using them. A mechanism for exchanging electronic cash was explored, as well as agent-based schemes for scheduling and fault-tolerance.
Metabolic flux profiling of <i>Escherichia coli</i> mutants in central carbon metabolism using GC‐MS (2003)

We describe here a novel methodology for rapid diagnosis of metabolic changes, which is based on probabilistic equations that relate GC-MS-derived mass distributions in proteinogenic amino acids to in vivo enzyme activities. This metabolic flux ratio analysis by GC-MS provides a comprehensive perspective on central metabolism by quantifying 14 ratios of fluxes through converging pathways and reactions from [1-13C] and [U-13C]glucose experiments. Reliability and accuracy of this method were experimentally verified by successfully capturing expected flux responses of Escherichia coli to environmental modifications and seven knockout mutations in all major pathways of central metabolism. Furthermore, several mutants exhibited additional, unexpected flux responses that provide new insights into the behavior of the metabolic network in its entirety. Most prominently, the low in vivo activity of the Entner-Doudoroff pathway in wild-type E. coli increased up to a contribution of 30% to glucose catabolism in mutants of glycolysis and TCA cycle. Moreover, glucose 6-phosphate dehydrogenase mutants catabolized glucose not exclusively via glycolysis, suggesting a yet unidentified bypass of this reaction. Although strongly affected by environmental conditions, a stable balance between anaplerotic and TCA cycle flux was maintained by all mutants in the upper part of metabolism. Overall, our results provide quantitative insight into flux changes that bring about the resilience of metabolic networks to disruption.
A Non‐Surgical Rat Model of Foreign Body‐Associated Urinary Tract Infection with <i>Pseudomonas aeruginosa</i> (2001)

This study established a rat model of foreign body-associated urinary tract infection. A spiral polyethylene tube (PT) was placed transurethrally into the bladder without surgical manipulation, followed by transurethral inoculation with Pseudomonas aeruginosa. The persistence of P. aeruginosa in the kidneys and bladder was significantly enhanced by placement of the PT, whereas the bacteria were eliminated rapidly from the urinary tract in the animals without the PT. Scanning electron microscopy revealed a thick biofilm on the surface of the PT from the early stage of infection. Histopathologically, acute pyelonephritis was followed by chronic renal inflammation as well as continuous and sporadic polymorphonuclear leukocyte accumulation and hemorrhage in the pelvis and adjacent tissues, suggesting continuous ascending introduction of the bacteria from the biofilm adhering to the PT. We believe our model simulates the pathophysiology of foreign body-associated urinary tract infection characterized by biofilm formation on the surface of a foreign body.

Improvement of angle and voltage stability by control of batteries using wide-area measurement system in power systems (2012)

In this paper, a real-time control scheme of BESSs (battery energy storage systems) on EHV (extra-high voltage) network is studied to improve angle and voltage stability in the power system. The proposed control scheme assumes to adopt wide-area measurement system equipped with PMUs (phasor measurement units). By monitoring internal voltage and rotor speed of generators in real-time, active and reactive power injection by the BESSs are controlled to suppress an increase of an energy function and rotor speed of the critical generator in the emergency state. Numerical simulations are conducted on a multi-machine power system with multiple BESSs. The effectiveness of the proposed method on the transient stability and the short-term voltage stability is verified under fault conditions such as a grounding fault and a generator contingency. The results show the improvement of the transient stability and the short-term voltage stability by controlling the BESSs.
Differential Laser Heterodyne Micrometrology (1985)

Heterodyne techniques have proved to be a very sensitive tool for measuring minute dynamic phase changes imposed on an optical beam. In this paper, we review the application of this powerful tool to the area of micrometrology. By using a differential geometry that measures the phase difference of reflected or transmitted light from two adjacent points on a sample, it is possible to achieve a sensitivity of 0.35 A (or 0.75 X1 0-3 rad). Results of the surface studies on several samples are presented that clearly show the ability of the technique to image monomolecular layers and other minute surface perturbations.
Business Firm Performance Types And The Strategic Implications (2011)

This study reports the findings of five different performance types that exist among business firms. These types were: Growing firms, turnabout firms, stagnant firms, turnaround firms, and declining firms. Using multiple discriminant analysis, the strategic differences among the five types were revealed. These strategic differences were captured in three dimensions, namely, asset-acquisition, finance, and differentiation. The key results indicate that growing firms tended to emphasize differentiation; turnabout firms ranked low on almost all dimensions; stagnant firms were high on both asset-acquisition and differentiation; turnaround firms tended to focus on financial strategies, and declining firms placed little emphasis on differentiation. The promising use of multiple discriminant analysis as a tool for taxonomic research in strategic management was highlighted.
MicroRNAs in inflammatory bowel disease (2011)

MicroRNAs (miRNAs) are small, noncoding RNAs that regulate gene and protein expression. miRNAs are critical to a normal immune response and have altered expression in multiple immune-mediated disorders. This emerging role of miRNAs in the pathogenesis of multiple disease states has led to investigations into miRNA expression profiles in inflammatory bowel disease (IBD). The discovery of miRNAs in IBD is likely to contribute to our understanding of IBD pathogenesis and lead to clinical advances in IBD. This review focuses on miRNA expression in inflammation, autoimmune disorders, and inflammation-associated cancer, as well as their function in the biology and management of IBD.
