Effectiveness of prosthetic mandibular advancement for obstructive sleep apnea:Analysis by sleep position (1998)

Fifteen patients with obstructive sleep apnea were treated using prosthetic mandibular advancement (PMA). Each patient was evaluated in the supine and lateral decubitus positions with and without PMA. After PMA treatment, the mean intraesophageal pressure (Peso) in the supine position improved from -42.6 to -27.3 cmH2O and the mean apnea + hypopnea index (AHI) decreased from 48.8/h to 23.7/h. The mean Peso in the lateral decubitus position improved from -27.9 to -18.6 cmH2O and the mean AHI decreased from 9.6/h to 6.6/h. With PMA, respiratory, disturbance during sleep further improved by changing the body position from the supine to lateral decubitus position.
Collisions of Small Cloud Droplets: Gas Kinetic Effects (1972)

Gas kinetic effects in the region between two small approaching cloud droplets were investigated by means of slip flow theory. The resulting correction to the force coefficients derived for creeping flow eliminates the “collision barrier” noted in previous work and thus the need for assuming an abitrary collision criterion. It was found that inclusion of the gas kinetic correction leads to collision efficiencies for droplets <20 μ in radius that are somewhat larger than those previously calculated. The effect is unimportant for droplets >30 μ in radius.

TFT Amplifiers for Amorphous Silicon PIXEL Particle Detectors (1989)

We have investigated the application of thin film electronics technology to making a signal amplifier and readout circuit for amorphous silicon PIXEL particle detectors which can detect minimum ionizing particles.Characteristics of currently available TFTs are reviewed and preliminary designs of a-Si:H and poly-Si amplifiers for a 300 Jllll x 300 Jllll PIXEL array are proposed.Based on measurement of small signal parameters and noise spectrum of individual a-Si:H and poly-Si TFTs, the overall gain, time-response and signal-tonoise ratio are calculated.
Mechanisms of Vδ1 γδ T Cell Activation by Microbial Components (2004)

There are two major subsets of gammadelta T cell in humans. Vgamma2Vdelta2 T cells predominate in the circulation and significantly expand in vivo during a variety of infectious diseases. Ags identified for the Vdelta2 T cells are nonpeptide phosphate, amine, and aminobisphosphonate compounds. In contrast, Vdelta1-encoded TCRs account for the vast majority of gammadelta T cells in tissues such as intestine and spleen. Some of these T cells recognize CD1c and MHC class I-related chain (MICA/B) molecules [correction]. These T cells are cytotoxic and use both perforin- and Fas-mediated cytotoxicity. A fundamental question is how these gammadelta T cells are activated during microbial exposure to carry out effector functions. In this study, we provide evidence for a mechanism by which Vdelta1 gammadelta T cells are activated by inflammatory cytokines in the context of the Vdelta1 TCR. Dendritic cells are necessary as accessory cells for microbial Ag-mediated Vdelta1 gammadelta T cell activation. Cytokine (IL-12), adhesion (LFA3/CD2, LFA1/ICAM1) and costimulatory (MHC class I-related chain (MICA/B) molecules/NK-activating receptor G2D) molecules play a significant role along with Vdelta1 TCR in this activation.
Facile Multistep Synthesis of Isotruxene and Isotruxenone (2009)

Three multistep approaches toward facile syntheses of isotruxene (1) and isotruxenone (3) are reported. The ortho-para conjugated backbone in the precursor 4 was constructed by either Co-catalyzed [2 + 2 + 2] cyclotrimerization or the [4 + 2] Diels-Alder reactions. The regioselectivity of the triple intramolecular Friedel-Crafts acylation of 4 plays the key role in determining the overall yield. Compared to the previous one-step method, the current approaches are more efficient in terms of product yield (27-36% vs 4-18%) and purification (i.e., free of column chromatography).
The Effects of Oil Spills on Phytoplankton in an Arctic Lake and Ponds (1978)

The effect of oil spilled on Alaskan freshwater phytoplankton populations was studied in waters affected by natural oil seeps, by controlled crude oil spills in tundra thaw ponds and in a morainal lake, by subpond manipulations and bioassay experiments. The studies were carried out over a period of seven years. Regardless of dose the effects of oil were predictable in the small ponds. The zooplankton populations were virtually eliminated, and after an initial depression of primary productivity the photosynthetic rates returned to approximately prespill levels with a small increase in algal biomass. A markedly altered algal composition was an invariable effect of the response, with the elimination of a dominant flagellated form, Rhodomonas spp., in the case of the ponds. From the results of subpond manipulation experiments, evidence supports the hypothesis that elimination of grazers is the principal cause of altered species composition and increased biomass in these ponds. In our lake system there was a severe reduction in primary production during the season of the experimental spill. During the second year only the spring boom was suppressed by the added oil. Bioassay experiments supported the hypothesis that in such lakes, direct inhibition of algal photosynthesis may be important, although zooplankton were greatly reduced.
Effective Quantization Approaches for Recurrent Neural Networks (2018)

Deep learning, Recurrent Neural Networks (RNN) in particular have shown superior accuracy in a large variety of tasks including machine translation, language understanding, and movie frames generation. However, these deep learning approaches are very expensive in terms of computation. In most cases, Graphic Processing Units (GPUs) are in used for large scale implementations. Meanwhile, energy efficient RNN approaches are proposed for deploying solutions on special purpose hardware including Field Programming Gate Arrays (FPGAs) and mobile platforms. In this paper, we propose an effective quantization approach for Recurrent Neural Networks (RNN) techniques including Long Short-Term Memory (LSTM), Gated Recurrent Units (GRU), and Convolutional Long Short Term Memory (ConvLSTM). We have implemented different quantization methods including Binary Connect {-1, 1}, Ternary Connect {-1, 0, 1}, and Quaternary Connect {-1, -0.5, 0.5, 1}. These proposed approaches are evaluated on different datasets for sentiment analysis on IMDB and video frame predictions on the moving MNIST dataset. The experimental results are compared against the full precision versions of the LSTM, GRU, and ConvLSTM. They show promising results for both sentiment analysis and video frame prediction.
Dynamic Diels–Alder Reactions of 9,10‐Dimethylanthracene: Reversible Adduct Formation, Dynamic Exchange Processes and Thermal Fluorescence Modulation (2009)

Abstract Studies of the Diels–Alder reactions between 9,10‐dimethylanthracene and cyano‐functionalized dienophiles led to the identification and characterization of new dynamic systems under ambient conditions. Among these dienophiles were tricyanoethynylethylene derivatives, which gave access to reversible thermal switching of fluorescent properties through binding to and release of the dimethylanthracene partner.

Show A Tell: Using Speech Input for Image Interpretation and Annotation* (1997)

This research concerns the exploitation of linguistic context in vision. Linguistic context is qualitative in nature and is obtained dynamically. We view this as a new paradigm which is a golden mean between data driven object detection and site-model based vision. Our solution not only proposes new techniques for using qualitative contextual information, but also efficiently exploits existing image interpretation technology. The design and implementation of a system, ShoweATell, a multimedia system for semi-automated image annotation is discussed. This system, which combines advances in speech recognition, natural language processing and image understanding, is designed to facilitate the work of image analysts (IA). Adaptation of the current prototype to the task of change profiling and change detection is discussed.
High quantum efficiency dual wavelength resonant-cavity photodetector (1995)

A new dual-wavelength, resonant-cavity photodiode is described. It has previously been shown that the resonant-cavity structure can achieve high quantum efficiencies in a relatively narrow spectral region with thin absorbing regions. In this letter, a dual wavelength mirror is incorporated into the cavity to achieve operation in two wavelength regions. Peak external quantum efficiencies greater than 50% were demonstrated at 730 and 910 nm.
Macrophage Biology and Pathobiology in the Evolution of Immune Responses: A Functional Analysis (2001)

A number of general principles of macrophage biology and pathobiology are formulated to define the contribution of macrophages to the kinetics and sequencing of innate and adaptive immune responses more precisely. The application of these principles to modelling immune responses and to macrophage-based treatments of immune disorders is discussed. The concept of innate peripheral tolerance is developed. It is suggested that macrophage activation could be a primary determinant of nearly every aspect of immune responsiveness, both normal and abnormal, as might be predicted from the innate immune response to 'danger' being evolutionarily more primitive than the adaptive.
Panorama based point cloud reduction and registration (2013)

To reconstruct environments 3D point clouds acquired by laser scanners are registered. This is an important but also time consuming part of any mapping system for mobile robots. The time needed for mapping is drastically reduced when the size of the input data is reduced. This paper examines different ways of reducing the size of point clouds without losing vital information for the matching process. We present novel point cloud reduction methods on the basis of panorama images. It is shown that the reduced point clouds are ideally suited for feature based registration on panorama images. We evaluate the presented reduction methods based on their effect on the performance of the registration algorithm.
IFN-γ-deficient mice develop experimental autoimmune uveitis in the context of a deviant effector response (1997)

Experimental autoimmune uveitis (EAU) is a T cell-mediated disease that targets the neural retina and serves as a model of human uveitis. Uveitogenic effector T cells have a Th1-like phenotype (high IFN-gamma, low IL-4), and genetic susceptibility to EAU is associated with an elevated Th1 response. Here we investigate whether the ability to produce IFN-gamma is necessary for the development of EAU by immunizing IFN-gamma-deficient (GKO) mice with the uveitogenic protein interphotoreceptor retinoid binding protein (IRBP) and characterize the associated immunologic responses. GKO mice developed EAU comparable in severity and incidence to that of their wild-type littermates. However, the cytokine profile in their uveitic eyes as well as the cytokines produced by primed lymph node cells in response to IRBP showed a distinct profile: undiminished TNF-alpha and elevated IL-5, IL-6, IL-10, and lymphotoxin (but not IL-4) responses. The inflammatory infiltrate in GKO eyes contained an excess of granulocytes and IL-5- and IL-6-producing cells, but uveitic GKO mice did not up-regulate inducible nitric oxide synthase. GKOs had enhanced lymphocyte proliferation and delayed-type hypersensitivity responses to IRBP. Histology of the delayed-type hypersensitivity lesion in GKO had superimposed elements of an allergic-like response. Anti-IRBP Ab isotypes of GKO mice showed a reduction of IgG2a, but no enhancement of IgG1. Comparison of responses in +/+ and +/- wild-type mice revealed some limited evidence of a gene-dose effect. We conclude that IFN-gamma is not required for priming of pathogenic T cells or for effecting the retinal damage and photoreceptor loss typical of EAU. However, what appears to be a grossly similar disease is caused in the GKO by a deviant type of effector response.

High temperature (1200 C) ceramic-to-metal seal development (1972)

Two phases have been completed, of a program whose ultimate objective is the development of an alkali metal resistant, thermal shock resistant, leak-tight, and neutron radiation resistant ceramic-to-metal seal capable of operation at 1200 C for three to five years. The first phase involved the screening of platinum-base, vanadium-base and vanadium-niobium base brazes for the joining of Cb-1Zr or T-111 alloys to high purity alumina. The second phase involved studies of the performance of sealed capsule samples during 5000-hour aging tests at 800, 1000, and 1200 C in high vacuum. Sealed capsules which were made using pure vanadium braze, and were brazed at 1850 C for one minute, survived 64 thermal cycles to 1200 C at the heating/cooling rate of 100 C/minute. Vanadium braze samples survived 5000-hour aging tests at 800, 1000, and 1200 C. One thermally cycled sample survived a subsequent 5000-hour aging period at 1000 C, but another, at 1200 C, did not survive. It was concluded that a pure vanadium braze used to bond high purity alumina to Cb-1Zr alloy is the best of the systems studied, but that additional studies must be performed to establish its service temperature limitations for the desired three to five years' service.
Piezoelectric Roads: Energy Harvesting Method Using PiezoelectricTechnology (2016)

This article aims to assess the functionality of piezoelectricity in roads to utilise energy executed from the moving vehicles. The energy is converted into electrical energy using piezoelectric technology to replace fossil fuel in streetlight applications. The vitality of this technology arises as fossil fuels is being over consumed which makes it challenging to provide sufficient power in the next era as an effect of growing population. Being dependent on renewable energy to account for a greater global consumption level is essential to overcome the risks associated with fossil fuels. Piezoelectric road is a new energy evolution to provide a sustainable solution in terms of environment, economy, and social needs.
Evaluation of an enzyme-linked immunosorbent assay for the detection of antibody to Trichomonas vaginalis in sera and vaginal secretions. (1982)

Using a whole-cell antigen antibody to Trichomonas vaginalis was measured by an enzyme-linked immunosorbent assay (ELISA). IgG antibody was found in sera from only three of 99 children under 12 years of age. In contrast, serum IgG or IgM antibody or both were detected in 80.4% of women who had vaginal trichomoniasis and in 13.7% of uninfected women. Although antibody was found in cervical and vaginal secretions, the correlation between current infection and the presence of antibody was poorer than found between circulating antibody and infection. IgG or IgA antibody or both was detected in the secretions of 73.2% and 41% of infected and uninfected women respectively. This may be accounted for, at least partly, by previous infections since antibody, circulating or local, was found most often in women who had a history of trichomoniasis. There was no indication that some other vaginal micro-organism stimulated antibody directed against T vaginalis.
Bipolar Heteroleptic Green Iridium Dendrimers Containing Oligocarbazole and Oxadiazole Dendrons for Bright and Efficient Nondoped Electrophosphorescent Devices (2011)

Bipolar heteroleptic green light-emitting iridium (Ir) dendrimers G(OXD) and G(DOXD) have been designed and synthesized under mild conditions in high yields, in which the first C^N and second O^O ligands are functionalized with oligocarbazole- and oxadiazole-based dendrons, respectively. To avoid affecting the optical properties of the emissive iridium core, all the functional moieties are attached to the ligands through a flexible spacer. Compared with the unipolar dendrimer G(acac), dendrimers G(OXD) and G(DOXD) exhibit the close emission maxima of 511-512 nm and photoluminescence quantum yield of 0.39-0.40 in a solution of toluene. Moreover, on going from G(acac) to G(OXD) and G(DOXD), we have found that the introduction of oxadiazole fragments decreases the lowest unoccupied molecular orbital (LUMO) energy levels to facilitate the electron injection and electron transporting, while their highest occupied molecular orbital (HOMO) energy levels remain unchanged. This means that, we can individually tune the HOMO and LUMO energy levels based on the heteroleptic structure to ensure the relative independence between the hole and electron in the emitting layer (EML), which is a favorable feature for bipolar optoelectronic materials. As a result, a bilayer nondoped electrophosphorescent device with G(DOXD) as the EML gives a maximum luminous efficiency of 25.5 cd A(-1) (η(ext): 7.4%) and a brightness of 33,880 cd m(-2). In comparison to G(acac) (17.2 cd A(-1), 17,680 cd m(-2)), both the efficiency and brightness are improved by about 1.5 and 2 times, respectively. These state-of-the-art performances indicate the potential of these bipolar heteroleptic iridium dendrimers as solution-processible emitting materials for nondoped device applications.

Nucleus Pulposus Replacement (2005)

Although some of the newly designed prosthesis have shown some promising results in preclinical studies, rigorous short- and long-term clinical evaluations will be critical in evaluating their true efficacy.
Surgical rubber gloves impervious to methylmethacrylate monomer (1984)

Conventional surgical rubber gloves are permeable to the methylmethacrylate monomer (MMM) of acrylic bone cement. An in vitro technique was used which proved butyl rubber gloves, 0.48 mm thick, to be impervious to MMM. to avoid sensitization, butyl rubber gloves may be recommended to persons who are in contact with MMM. Such gloves should be worn by persons with known contact sensitization to MMM.
Characterization of gap junction genes expressed in F9 embryonic carcinoma cells: molecular cloning of mouse connexin31 and -45 cDNAs. (1992)

In an attempt to characterize connexin genes expressed early in mouse development we screened a cDNA library from mouse F9 embryonic carcinoma cells with mouse connexin37 cDNA and mouse connexin31.1 genomic DNA under low stringency of hybridization. We detected 5 different connexin cDNAs coding for mouse connexins31, -31.1, -32, -43, and -45 (reviewed in Willecke et al., Eur. J. Cell Biol. 56, 1-7 (1991)). Here we describe characterization of mouse connexin31 cDNA coding for a protein of 270 amino acids (Mr 30,905) that shows 8 amino acid exchanges compared to its rat analog recently deduced from its genomic sequence. Mouse connexin45 cDNA codes for a protein of 396 amino acids (Mr 45,671) that exhibits 84% amino acid identity compared to its chick analog described. Cx31 and Cx45 are coded for by single genes in the mouse genome. After Northern blot hybridization, we detected two Cx31 transcripts of 1.9 and 2.3 kb in total mouse RNA from skin, keratinocyte-derived cell lines, and in testis. Cx45 cDNA hybridized to a 2.2 kb mRNA in lung, brain, skin, heart, and intestine. This transcript showed maximal expression in adult lung and in embryonic tissues tested (brain, skin, kidney) where it was at least 40-fold more abundant than in the corresponding adult tissues.
Image Gradient Detection with Hough Transform (2008)

In this paper, we propose gradient detection system of the vertical straight line using the Hough Transform after extracting from the color images. The input color images can be used to a method for detecting a gradient from only the luminance component of animage. In edge detection, traditional method of the mask of vertical edge detection can detect with the one direction of the image change but proposed method can detect bi-direction. Since the Hough Transform is required much time for processing, our method can be improved processing time through experimentally calculating valid pixel.
Bridging the Semantic Gaps of GPU Acceleration for Scale-out CNN-based Big Data Processing (2016)

Convolutional Neural Networks (CNNs) have substantially advanced the state-of-the-art accuracies of object recognition, which is the core function of a myriad of modern multimedia processing techniques such as image/video processing, speech recognition, and natural language processing. GPU-based accelerators gained increasing attention because a large amount of highly parallel neurons in CNN naturally matches the GPU computation pattern. In this work, we perform comprehensive experiments to investigate the performance bottlenecks and overheads of current GPU acceleration platform for scale-out CNN-based big data processing.
A Probabilistic Causal Model for Diagnostic Problem Solving Part I: Integrating Symbolic Causal Inference with Numeric Probabilistic Inference (1987)

The issue of how to effectively integrate and use symbolic causal knowledge with numeric estimates of probabilities in abductive diagnostic expert systems is examined. In particular, a formal probabilistic causal model that integrates Bayesian classification with a domain-independent artificial intelligence model of diagnostic problem solving (parsimonious covering theory) is developed. Through a careful analysis, it is shown that the causal relationships in a general diagnostic domain can be used to remove the barriers to applying Bayesian classification effectively (large number of probabilities required as part of the knowledge base, certain unrealistic independence assumptions, the explosion of diagnostic hypotheses that occurs when multiple disorders can occur simultaneously, etc.). Further, this analysis provides insight into which notions of "parsimony" may be relevant in a given application area. In a companion paper, Part Two, a computationally efficient diagnostic strategy based on the probabilistic causal model discussed in this paper is developed.
A Physical Map of Arabidopsis thaliana Chromosome 3 Represented by Two Contigs of CIC YAC, P1, TAC and BAC Clones (1998)

We have constructed a physical map of Arabidopsis thaliana chromosome 3 by ordering the clones from CIC YAC, P1, TAC and BAC libraries using the sequences of a variety of genetic and EST markers and terminal sequences of clones. The markers used were 112 DNA markers, 145 YAC end sequences, and 156 end sequences of P1, TAC and BAC clones. The entire genome of chromosome 3, except for the centromeric and telomeric regions, was covered by two large contigs, 13.6 Mb and 9.2 Mb long. This physical map will facilitate map-based cloning experiments as well as genome sequencing of chromosome 3. The map and end sequence information are available on the KAOS (Kazusa Arabidopsis data Opening Site) web site at http://www.kazusa.or.jp/arabi/.
