A Subset of Men With Age-Related Decline in Testosterone Have Gonadotroph Autoantibodies (2016)

A subset of older men with age-related low T levels have specific antibodies against the gonadotrophs. Whether these antibodies are pathogenic and contributory to the age-related decline in T remains to be established.
Self-cleavage of hepatitis delta virus genomic strand RNA is enhanced under partially denaturing conditions (1990)

Self-cleavage of a polyribonucleotide containing an autocleaving sequence from the genomic strand of hepatitis delta virus was enhanced by conditions that destabilized RNA structure. Self-cleavage of the transcripts used in this study required Mg2+ (or another divalent cation), and in the absence of denaturants, maximum cleavage was observed at very low Mg2+ concentrations (0.05-0.1 mM). However, at 37 degrees C and in the presence of 2-10 mM Mg2+ the rate of cleavage was increased as much as 50-fold with the addition of urea to 5 M or formamide to 10 M. Cleavage was prevented by higher concentrations of the same reagents (9.5 M urea or 22.5 M formamide), presumably because a structure required for self-cleavage is disrupted by strongly denaturing conditions. In contrast to a previous report [Wu, H.-N., & Lai, M. M. C. (1989) Science 243, 652-654], we find that chelating Mg2+ with EDTA terminates the cleavage reaction without promoting measurable amounts of ligation of the cleavage products. The ability of denaturants to promote rapid self-cleavage in vitro raises the possibility that an unidentified factor could have a similar effect in vivo.
An 8-kb/s conjugate structure CELP (CS-CELP) speech coder (1996)

This paper describes a high-quality 8-kb/s speech coder called conjugate structure code-excited linear prediction (CS-CELP) with a 10-ms frame length. To provide a short delay and high quality under both error-free and channel error conditions, it uses three new schemes: line spectrum pair (LSP) quantization using interframe prediction, preselection in the codebook search, and gain vector quantization (VQ) with backward prediction. The LSP parameters are quantized by using multistage VQ with moving-average (MA) prediction. This scheme can operate efficiently with various frequency responses of speech. The preselection of the codebook reduces the computational complexity and improves the robustness to channel errors. The gain VQ with backward prediction can provide a high quality and robustness without transmission of input speech power information. A conjugate structure for both random codebook and gain codebook is introduced to improve the ability to handle random bit errors and to reduce codebook storage memory requirements. Subjective testing indicates that the quality of this coder is equivalent to that of 32-kb/s adaptive differential pulse code modulation (ADPCM) under error-free conditions. Testing has further demonstrated that the coder is robust against random bit errors.
Cryogenic performance of a high-speed GaInAs/InP p-i-n photodiode (1997)

The cryogenic performance of a high-speed GaInAs/InP p-i-n photodiode, with graded bandgap layers at the heterostructure interfaces, was investigated for the first time. DC measurements show that the dark current of the diode decreases sharply as the temperature decreases from 300 to 200 K. A factor of 1000 in dark current reduction was found for this photodiode, when it was cooled from room temperature to about 150 K. Similar modulation bandwidths were found for this device for temperatures between 9 and 300 K, with a bandwidth greater than 20 GHz. No degradation was found in performance at cryogenic temperature compared to room temperature. This enables direct integration of high-speed photodiodes with superconductive and other cryogenic electronics.
Optimization of the Loney's solenoid through quasi-analytical strategies: a benchmark problem reconsidered (1997)

A benchmark for inverse problems in magnetostatics, characterized by four geometrical design variables, is revisited; its solution is tackled by means of a quasi-analytical optimization methodology. A set of initial designs, generated in a random way, is considered; the study of the functional dependence of the optimization results on the starting configurations is investigated.
Pathological findings of angiographically occult vascular malformation. (2002)

Forty cases with angiographically occult vascular malformations (AOVMs), in which the diagnosis was confirmed pathologically, are analysed. Pathology of the AOVMs were classified into 22 AVMs (20 thrombosed, two cryptic), 16 cavernous malformations and two capillary telangiectasias. The location of AOVMs were in the cerebral hemisphere (32), cerebellum (3), thalamus (2), lateral ventricle (1), brain stem (1) and optic nerve (1). Common characteristic histopathological features between thrombosed AVMs and cavernous malformations were that the malformations had subclinically bled in the past and apparently had proceeded to undergo various degree of thrombosis, fibrosis and calcification. However, in addition to these findings, the thrombosed AVMs showed a contribution of arterial components, hypertrophied vascular wall and intervening gliotic tissue. On the other hand, the cavernous malformations showed closely packed abnormal vessels with surrounding collagen band. All cryptic AVMs presented with haemorrhagic episodes and small nidus within clot were proven in histological specimens. Common histopathological findings between thrombosed AVMs and cavernous malformations are discussed.
Angiotensin-(1-7) Decreases Cell Growth and Angiogenesis of Human Nasopharyngeal Carcinoma Xenografts (2015)

Angiotensin-(1-7) [Ang-(1-7)] is an endogenous, heptapeptide hormone acting through the Mas receptor (MasR), with antiproliferative and antiangiogenic properties. Recent studies have shown that Ang-(1-7) has an antiproliferative action on lung adenocarcinoma cells and prostate cancer cells. In this study, we report that MasR levels were significantly upregulated in nasopharyngeal carcinoma (NPC) specimens and NPC cell lines. Viral vector-mediated expression of Ang-(1-7) dramatically suppressed NPC cell proliferation and migration in vitro. These effects were completely blocked by the specific Ang-(1-7) receptor antagonist A-779, suggesting that they are mediated by the Ang-(1-7) receptor Mas. In this study, Ang-(1-7) not only caused a significant reduction in the growth of human nasopharyngeal xenografts, but also markedly decreased vessel density, suggesting that the heptapeptide inhibits angiogenesis to reduce tumor size. Mechanistic investigations revealed that Ang-(1-7) inhibited the expression of the proangiogenic factors VEGF and PlGF. Taken together, the data suggest that upregulation of MasR could be used as a diagnostic marker of NPC and Ang-(1-7) may be a novel therapeutic agent for nasopharyngeal cancer therapy because it exerts significant antiangiogenic activity.

Transition from thermal diffusion to heat accumulation in high repetition rate femtosecond laser writing of buried optical waveguides (2008)

A variable (0.2 to 5 MHz) repetition rate femtosecond laser was applied to delineate the role of thermal diffusion and heat accumulation effects in forming low-loss optical waveguides in borosilicate glass across a broad range of laser exposure conditions. For the first time, a smooth transition from diffusion-only transport at 200 kHz repetition rate to strong heat accumulation effects at 0.5 to 2 MHz was observed and shown to drive significant variations in waveguide morphology, with rapidly increasing waveguide diameter that accurately followed a simple thermal diffusion model over all exposure variables tested. Amongst these strong thermal trends, a common exposure window of 200 mW average power and approximately 15-mm/s scan speed was discovered across the range of 200 kHz to 2 MHz repetition rates for minimizing insertion loss despite a 10-fold drop in laser pulse energy. Waveguide morphology and thermal modeling indicate that strong thermal diffusion effects at 200 kHz give way to a weak heat accumulation effect at approximately 1 microJ pulse energy for generating low loss waveguides, while stronger heat accumulation effects above 1-MHz repetition rate offered overall superior guiding. A comprehensive characterization of waveguide properties is presented for laser writing in the thermal diffusion and heat accumulation regimes. The waveguides are shown to be thermally stable up to 800 degrees C and can be written in a convenient 520 microm depth range with low spherical aberration.
NVH and Modal Analysis of Thermal-Acoustical Protective Shields (2004)

<div class="htmlview paragraph">The exhaust manifold heat shield is made of different material layers and is bolted to the engine exhaust manifold. The exhaust manifold heat shield has been identified as a potential major noise contributor among the engine components during normal operation, which is to protect nearby components from damage due to high heat. To reduce the noise radiated from the exhaust system, a thermal acoustic protective shield (TAPS) has been developed to act as a partial acoustic enclosure. This paper will discuss the importance of controlling NVH and what can be done design-wise to improve the TAPS characteristics.</div> <div class="htmlview paragraph">The paper discusses the impact of damping and vibration, how they are modeled. Further the present study analyzes the radiated sound pressure level (SPL) of a thermal acoustic protective shield by using the finite element analysis (FEA). The analyses are performed using the fully coupled structural-acoustic method and the sequentially coupled structural-acoustic method. A damping material has been incorporated into the core of the multi-layer shield allowing it to dissipate the mechanical energy coming from the exhaust manifold. Results show that the radiated sound level of a shield with a damping layer is noticeably lower than that of an undamped shield.</div>
New Inverting Modified CUK Converter Configurations with Switched Inductor (MCCSI) for High-Voltage/Low-Current Renewable Applications (2018)

Inverting Modified CUK Converter with Switched Inductor (MCCSI) configurations are articulated in the paper for high-voltage and low-current renewable energy applications. Based on the Switched Inductor (SI) position in MCC converter, four new modified CUK converter configurations are proposed as MCCSI-XLL, MCCSI-LYL, MCCSI-LLZ and MCCSI-XYZ. The mathematical analysis and comparison is shown in terms of the voltage conversion ratio, number of active and reactive components. The mode of operation of MCCSI-XLL configuration is discussed to understand the working concept of MCCSI configurations. The striking features of the proposed configurations are discussed in details. Operation of the proposed converter is verified by simulation in MatLab R2016a.
Absence of P-selectin delays fatty streak formation in mice. (1997)

P-selectin is expressed on activated endothelium and platelets where it can bind monocytes, neutrophils, stimulated T cells, and platelets. Because recruitment of these cells is critical for atherosclerotic lesion development, we examined whether P-selectin might play a role in atherosclerosis. We intercrossed P-selectin-deficient mice with mice lacking the low density lipoprotein receptor (LDLR) because these mice readily develop atherosclerotic lesions on diets rich in saturated fat and cholesterol. The atherogenic diet stimulated leukocyte rolling in the mesenteric venules of LDLR-deficient mice, and the increase in adhesiveness of the vessels was P-selectin-dependent. Most likely due to the reduced leukocyte interaction with the vessel wall, P-selectin-deficient mice on diet for 8-20 wk formed significantly smaller fatty streaks in the cusp region of the aortae than did P-selectin-positive mice. This difference was more prominent in males. At 37 wk on diet, the lesions in the LDLR-deficient animals progressed to the fibrous plaque stage and were distributed throughout the entire aorta; their size or distribution was no longer dependent on P-selectin. Our results show that P-selectin-mediated adhesion is an important factor in the development of early atherosclerotic lesions, and that adhesion molecules such as P-selectin are involved in the complex process of atherosclerosis.

Communicative gestures in coreference identification in multiparty meetings (2009)

During multiparty meetings, participants can use non-verbal modalities such as hand gestures to make reference to the shared environment. Therefore, one hypothesis is that incorporating hand gestures can improve coreference identification, a task that automatically identifies what participants refer to with their linguistic expressions. To evaluate this hypothesis, this paper examines the role of hand gestures in coreference identification, in particular, focusing on two questions: (1) what signals can distinguish communicative gestures that can potentially help coreference identification from non-communicative gestures; and (2) in what ways can communicative gestures help coreference identification. Based on the AMI data, our empirical results have shown that the length of gesture production is highly indicative of whether a gesture is communicative and potentially helpful in language understanding. Our experiments on the automated identification of coreferring expressions indicate that while the incorporation of simple gesture features does not improve overall performance, it does show potential on expressions referring to participants, an important and unique component of the meeting domain. A further analysis suggests that communicative gestures provide both redundant and complementary information, but further domain modeling and world knowledge incorporation is required to take full advantage of information that is complementary.

<title>Targeted and all-sky search for nanosecond optical pulses at Harvard-Smithsonian</title> (2001)

We have built a system to detect nanosecond pulsed optical signals from a target list of some 10,000 sun-like stars, and have made some 20,000 observations during its two years of operation. A beamsplitter feeds a pair of hybrid avalanche photodetectors at the focal plane of the 1.5m Cassegrain at the Harvard/Smithsonian Oak Ridge Observatory (Agassiz Station), with a coincidence triggering measurement of pulse width and intensity at sub-nanosecond resolution. A flexible web-enabled database, combined with mercifully low background coincidence rates (approximately 1 event per night), makes it easy to sort through far-flung data in search of repeated events from any candidate star. An identical system will soon begin observations, synchronized with ours, at the 0.9m Cassegrain at Princeton University. These will permit unambiguous identification of even a solitary pulse. We are planning an all-sky search for optical pulses, using a dedicated 1.8m f/2.4 spherical glass light bucket and an array of pixelated photomultipliers deployed in a pair of matched focal planes. The sky pixels, 1.5 arcmin square, tessellate a 1.6 by 0.2 degree patch of sky in transit mode, covering the Northern sky in approximately 150 clear nights. Fast custom IC electronics will monitor corresponding pixels for coincident optical pulses of nanosecond timescale, triggering storage of a digitized waveform of the light flash.
Virtual Test and Training Range A Logical Range Partnership for the Future, (1998)

Abstract : This is a review of the above article which was published in the ITEA Journal, the Journal of the International Test and Evaluation Association, December 1997/January 1998 issue. In this article the author addresses a very wide ranging, highly technical, and complex subject in an overview of six pages. Considering the limitations on the length of articles in the ITEA Journal, he provided an excellent summary. However, the subject appears to be too complex for such a short work to provide more than a general understanding of what the Logical Range is and what it will attempt to accomplish.
