Improved Part-based Human Detection Using Depth Information (2011)

In this paper, we propose a part-based human detection method in which the faces and upper parts of human bodies are first detected separately and then merged. In a crowded scene, it is very difficult to merge the detected faces and upper body parts accurately. We solve the problem by using the depth information obtained from the images. We use a TOF (Time of Flight) camera to capture amplitude and depth images. The detector detects the faces and upper body parts from the amplitude images and merges the parts by using a modified Mean Shift clustering algorithm with depth information. Experimental results show that the proposed method shows good performance in the case of crowded scenes. The proposed method is also better than the human detection method in which depth images are used.
High reliability of nanometer-range N/sub 2/O-nitrided oxides due to suppressing hole injection (2002)

Hole transport and trapping in N/sub 2/O-nitrided oxides have been studied. It is shown that N/sub 2/O-nitridation of oxides suppresses hole injection into the oxides. The suppression of hole injection is a mechanism leading to the enhancement of reliability of the nitrided oxides under channel hot-hole and F-N stresses.
High pressure phase equilibria of interest for production and transport of natural gas and oil (1995)

Knowledge of the phase behavior of reservoir fluids is very important for production and transport of natural gas and oil. In this presentation three examples are given which illustrate this thesis. The first example deals with the prediction of the condensation behavior of lean natural gas. A new characterization procedure for the heavy-end fractions of natural gas will be presented. In the second example an explanation is given for the phenomenon of retrograde condensation of a second, heavy liquid phase in the presence of a another liquid phase and a vapor phase, which is observed in some gas condensates. This explanation is based on an experimental study on ternary model systems. The third and last example is concerned with the phase behavior of hyperbaric reservoir fluids. Also in this case the experimental study of model systems gives an insight in the systematics of vapor-liquid equilibria and solid-fluid equilibria (wax formation) with changing reservoir composition.

The reaction between cyanide ion and nitrones; a novel imidazole synthesis (1980)

By contrast with the CN-diphenylnitrones, cold aqueous ethanolic potassium cyanide converts N-methyl-C-phenylnitrone into 1-methyl-4,5-diphenylimidazole. The scope of this reaction has been investigated, and shown to proceed via intermediate cyano-imines, some of which have been synthesised by alternative routes.
Ultrahigh energy cosmic rays as heavy nuclei from cluster accretion shocks (2007)

Large-scale accretion shocks around massive clusters of galaxies, generically expected in the cold dark matter scenario of cosmological structure formation, are shown to be plausible sources of the observed ultrahigh energy cosmic rays (UHECRs) by accelerating a mixture of heavy nuclei including the iron group elements. Current observations can be explained if the source composition at injection for the heavier nuclei is somewhat enhanced from simple expectations for the accreting gas. The proposed picture should be clearly testable by current and upcoming facilities in the near future through characteristic features in the UHECR spectrum, composition and anisotropy, in particular the rapid increase of the average mass composition with energy from $10^{19}$ to $10^{20}$ eV.
Heat Treatment of Amorphous and Polycrystalline Silicon Thin Films with H<sub>2</sub>O Vapor (1998)

Changes in electrical and optical properties induced by heat treatment with H 2 O vapor at 350 °C are reported for laser-induced amorphous silicon, low pressure chemical vapor amorphous silicon (LPCVD a-Si) and laser crystallized polycrystalline silicon films. The dark conductivity was reduced and the photoconductivity was increased by the heat treatment for these films. The optical absorption in the photon energy range lower than 1.5 eV was reduced for the a-Si films. The optical band gap was slightly increased from 1.48 eV to 1.51 eV for the LPCVD a-Si. The increase in hydrogen concentration was less than 2×10 20 cm -3 after the treatment. These results show that the heat treatment with H 2 O vapor reduces the defect density in the silicon films with a small amount of hydrogen incorporation.
Evaluation of wafer bonded CMUTs with rectangular membranes featuring high fill factor (2008)

Increasing fill factor is one design approach used to increase average output displacement, output pressure, and sensitivity of capacitive micromachined ultrasonic transducers (CMUTs). For rectangular cells, the cell-to-cell spacing and the aspect ratio determine the fill factor. In this paper, we explore the effects of these parameters on performance, in particular the nonuniformity of collapse voltage between neighboring cells and presence of higher order modes in air or immersed operation. We used a white light interferometer to measure nonuniformity in deflection between neighboring cells. We found that reducing the cell-to-cell spacing could cause bending of the center support post, which amplifies nonuniformities in collapse voltage to 18.4% between neighboring cells. Using a 2-D finite element model (FEM), we found that for our designs, increasing the support post width to 1.67 times the membrane thickness alleviated the post bending problem. Using impedance and interferometer measurements to observe the effects of aspect ratio on higher order modes, we found that the (1,3) modal frequency approached the (1,1) modal frequency as the aspect ratio of the rectangles increased. In air operation, under continuous wave (CW) excitation at the center frequency, the rectangular cells behaved in the (1,1) mode. In immersion, because of dispersive guided modes, these cells operated in a higher order mode when excited with a CW signal at the center frequency. This contributed to a loss of output pressure; for this reason our rectangular design was unsuitable for CW operation in immersion.
[Morphometric analysis of the glomeruli and juxtaglomerular apparatus of rat kidneys during the course of experimental hypokinesia]. (1980)

In the hypokinetic study a certain correlation between variations in the means of the volume of cortical and juxtamedullary glomerules and the function of the juxtaglomerular apparatus has been established. It is hypothesized that at early hypokinesia renal vascular changes are nonspecific. The phenomenon of renal excretion of fluids and electrolytes is explained in terms of a simultaneous increase in the reninangiotensin activity and 11-hydroxycorticosteroid content in plasma.

Visibility related to backscatter at 106 μm (1985)

A relationship was developed between visibility and backscatter at 1.06-μm wavelength. These results were developed from information derived from eighty-eight height profiles of particle size distributions taken in clouds, fog, and haze. This relationship broke down into two regions, a linear region and a nonlinear region. The linear region, the lower visibility, extends from 750 to 200–300 m. The form of this equation is V = 3.912/[1.2(1/km) + 18B]. This agrees with the theory. The second portion was a curve covering the range from 750 m to 4 km. The form of the curve is V = 3.912/[ln(A + CB2)]. These curves fit the data rather well.
RESIDUAL EFFECTS OF METAL FORMING: THEIR EFFECT ON CRASH RESULTS (2001)

The thickness changes and work hardening arising during the forming process are generally ignored in crash analysis. This paper quantifies the effect of the forming process on crash response of a typical car of stamped steel construction using an analytical study. Forming results for fourteen panels of a medium-sized car were calculated using a one-step stamping analysis code. These were imported into the crash model, and crash results compared with and without the forming effects. The time taken to generate the forming data by a variety of methods is quantified, and the trade-off between the time taken and accuracy is examined. An efficient method of importing the forming data into the crash model is presented.
Alpha-Toxin of<i>Clostridium perfringens</i>Is Not an Essential Virulence Factor in Necrotic Enteritis in Chickens (2006)

The Clostridium perfringens alpha-toxin has previously been implicated as the major virulence factor in necrotic enteritis in chickens, although definitive proof has not been reported. In this study an alpha-toxin mutant was constructed in a virulent chicken isolate and shown to retain full virulence in a chicken disease model. These results demonstrated that alpha-toxin is not an essential virulence factor in the pathogenesis of necrotic enteritis in chickens.

DARPP-32, a dopamine- and adenosine 3':5'-monophosphate-regulated phosphoprotein enriched in dopamine-innervated brain regions. I. Regional and cellular distribution in the rat brain (1984)

The present study documents the existence in mammalian brain of a phosphoprotein which may play a biological role in dopaminoceptive neurons. This protein has been designated DARPP-32 (dopamine- and adenosine 3':5'-monophosphate-regulated phosphoprotein-32,000). The regional distribution of DARPP-32 in the rat brain follows the general pattern of dopaminergic innervation. DARPP-32 is present in dopaminoceptive rather than dopaminergic neurons. Moreover, it appears to be concentrated in a subpopulation of dopaminoceptive cells, namely those containing D-1 receptors (dopamine receptors coupled to adenylate cyclase activation), where it is localized in cell bodies, dendrites, axons, and nerve terminals. DARPP-32 is phosphorylated in intact cells from the caudatoputamen by dopamine and by 8-bromo-cyclic adenosine 3':5'-monophosphate and in cell-free preparations by cyclic adenosine 3':5'-monophosphate-dependent protein kinase. In two accompanying papers, we report the purification and biochemical characterization of DARPP-32 (Hemmings, H.C., Jr., A.C. Nairn, D.W. Aswad, and P. Greengard (1984) J. Neurosci. 4: 99-110) and the immunocytochemical localization of this phosphoprotein (Ouimet, C.C., P. Miller, H.C. Hemmings, Jr., S.I. Walaas, and P. Greengard (1984) J. Neurosci. 4: 111-124).
A conceptual density‐based approach for the disambiguation of toponyms (2008)

Abstract Nowadays, a huge quantity of information is stored in digital format. A great portion of this information is constituted by textual and unstructured documents, where geographical references are usually given by means of place names. A common problem with textual information retrieval is represented by polysemous words, that is, words can have more than one sense. This problem is present also in the geographical domain: place names may refer to different locations in the world. In this paper we investigate the use of our word sense disambiguation technique in the geographical domain, with the aim of resolving ambiguous place names. Our technique is based on WordNet conceptual density. Due to the lack of a reference corpus tagged with WordNet senses, we carried out the experiments over a set of 1,210 place names extracted from the SemCor corpus that we named GeoSemCor and made publicly available. We compared our method with the most‐frequent baseline and the enhanced‐Lesk method, which previously has not been tested in large contexts. The results show that a better precision can be achieved by using a small context (phrase level), whereas a greater coverage can be obtained by using large contexts (document level). The proposed method should be tested with other corpora, due to the fact that our experiments evidenced the excessive bias towards the most‐frequent sense of the GeoSemCor.

PENNSYLVANIA : TRANSPORTATION FOR THE COMMON GOOD (2001)

This article presents a survey of signature transit operations in Pennsylvania, starting with a history of growth of transit in the state. A key development was linking passage of the state lottery in 1973 to funding transportation for the elderly in a program called Shared-Ride. It subsidizes fixed-route and demand-responsive transit systems for users older than 65. Another large effort is the Medical Assistance Transportation Program, which pays local transit agencies to carry people to health care appointments. Statewide support for transit comes from $260 million in general funds for urban systems and $2.6 million in rural ones, plus $70 million in gas tax revenues for investments statewide. Among the highlighted systems are two large agencies that contract out the actual operation of vehicles; a rural provider; regional agencies, including one that consolidated two separate operators and overnight repainted the two fleets and reconfigured routes to make them into one, more visible operation; and a paratransit service.
Peptidylarginine Deiminase Inhibitor Suppresses Neutrophil Extracellular Trap Formation and MPO-ANCA Production (2016)

Myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA)-associated vasculitis is a systemic small-vessel vasculitis, wherein, MPO-ANCA plays a critical role in the pathogenesis. Neutrophil extracellular traps (NETs) released from activated neutrophils are composed of extracellular web-like DNA and antimicrobial proteins, including MPO. Diverse stimuli, such as phorbol myristate acetate (PMA) and ligands of toll-like receptors (TLR), induce NETs. Although TLR-mediated NET formation can occur with preservation of living neutrophilic functions (called vital NETosis), PMA-stimulated neutrophils undergo cell death with NET formation (called suicidal NETosis). In the process of suicidal NETosis, histones are citrullinated by peptidylarginine deiminase 4 (PAD4). Since this step is necessary for decondensation of DNA, PAD4 plays a pivotal role in suicidal NETosis. Although NETs are essential for elimination of microorganisms, excessive formation of NETs has been suggested to be implicated in MPO-ANCA production. This study aimed to determine if pan-PAD inhibitors could suppress MPO-ANCA production in vivo. At first, NETs were induced in peripheral blood neutrophils derived from healthy donors (1 × 10(6)/ml) by stimulation with 20 nM PMA with or without 20 μM propylthiouracil (PTU), an anti-thyroid drug. We then determined that the in vitro NET formation was inhibited completely by 200 μM Cl-amidine, a pan-PAD inhibitor. Next, we established mouse models with MPO-ANCA production. BALB/c mice were given intraperitoneal (i.p.) injection of PMA (50 ng at days 0 and 7) and oral PTU (2.5 mg/day) for 2 weeks. These mice were divided into two groups; the first group was given daily i.p. injection of PBS (200 μl/day) (n = 13) and the other group with daily i.p. injection of Cl-amidine (0.3 mg/200 μl PBS/day) (n = 7). Two weeks later, citrullination as an indicator of NET formation in the peritoneum and serum MPO-ANCA titer was compared between the two groups. Results demonstrated that citrullination in the peritoneum was significantly reduced in the Cl-amidine-treated mice compared with the vehicle-injected control mice (38% reduction). Additionally, the serum MPO-ANCA titer of the Cl-amidine-treated mice (32.3 ± 31.0 ng/ml) was significantly lower than that in the vehicle-injected mice (132.1 ± 41.6 ng/ml). The collective findings indicate that excessive formation of NETs may be implicated in MPO-ANCA production in vivo.
Facile Modulation of Antibody Fucosylation with Small Molecule Fucostatin Inhibitors and Cocrystal Structure with GDP-Mannose 4,6-Dehydratase (2016)

The efficacy of therapeutic antibodies that induce antibody-dependent cellular cytotoxicity can be improved by reduced fucosylation. Consequently, fucosylation is a critical product attribute of monoclonal antibodies produced as protein therapeutics. Small molecule fucosylation inhibitors have also shown promise as potential therapeutics in animal models of tumors, arthritis, and sickle cell disease. Potent small molecule metabolic inhibitors of cellular protein fucosylation, 6,6,6-trifluorofucose per-O-acetate and 6,6,6-trifluorofucose (fucostatin I), were identified that reduces the fucosylation of recombinantly expressed antibodies in cell culture in a concentration-dependent fashion enabling the controlled modulation of protein fucosylation levels. 6,6,6-Trifluorofucose binds at an allosteric site of GDP-mannose 4,6-dehydratase (GMD) as revealed for the first time by the X-ray cocrystal structure of a bound allosteric GMD inhibitor. 6,6,6-Trifluorofucose was found to be incorporated in place of fucose at low levels (<1%) in the glycans of recombinantly expressed antibodies. A fucose-1-phosphonate analog, fucostatin II, was designed that inhibits fucosylation with no incorporation into antibody glycans, allowing the production of afucosylated antibodies in which the incorporation of non-native sugar is completely absent-a key advantage in the production of therapeutic antibodies, especially biosimilar antibodies. Inhibitor structure-activity relationships, identification of cellular and inhibitor metabolites in inhibitor-treated cells, fucose competition studies, and the production of recombinant antibodies with varying levels of fucosylation are described.
Laser amplifier control in 280 Mbit/s optical transmission system (1989)

The performance of a laser amplifier, with active stabilisation of the output power in a 280 Mbit/s repeatered optical fibre system, is reported. The stabilisation technique automatically adjusts the laser amplifier gain to compensate for changes in external environmental and optical effects.
Effects of Agricultural Limestone on Water Chemistry, Phytoplankton Productivity, and Fish Production in Soft Water Ponds (1975)

Five ponds treated with agricultural limestone and five control ponds were stocked with Tilapia aurea and fertilized every 2 weeks with ammonium nitrate and triple superphosphate. Initially, total hardness and total alkalinity of the waters in the 10 ponds averaged 7.8 and 13.7 mg/liter, respectively. Liming caused a fourfold increase in total hardness and total alkalinity. Limed ponds had higher rates of phytoplankton productivity and yielded a 25% greater weight of fish than control ponds.
Opposite roles of D1 and D5 dopamine receptors in locomotion revealed by selective antisense oligonucleotides (1998)

Contralateral rotations induced by the D1-like agonist SKF 38393 in unilaterally 6-hydroxydopamine-lesioned rats were completely prevented by the administration of the D1-like antagonist SCH 23390. A similar result was obtained after intracerebroventricular administration of an antisense oligodeoxynucleotide for the D1 receptor (D1R-as). Contrariwise, administration of a D5R-as potentiated the effects of SKF 38393, showing a 60% increase in the rotational scores. Both effects were reversible upon cessation of D1R-as or D5R-as treatment and were also specific since rotational scores in rats treated with vehicle or with a randomly designed oligodeoxynucleotide were not modified. These results suggest that whereas D1 receptors play a facilitatory role in locomotion, D5 receptors exert an inhibitory effect.
