The distribution of HLA on human lymphoid, bone marrow and peripheral blood cells (1979)

The cellular distribution and the differential expression of HLA on cell suspensions and tissue sections has been investigated using the monoclonal antibody W6-32, which reacts with the high molecular weight chain of the major histocompatibility antigen. Lymphocytes and platelets, as assessed by autoradiographic and immunoperoxidase labeling, were the most densely labeled cells. Myeloid precursors showed more labeling than mature neutrophils. Electron microscopic immunoperoxidase labeling showed a continuous distribution of HLA antigen on lymphoid and myeloid cell membranes. Erythroid precursors (including reticulocytes), although very weakly labeled, were clearly positive, in comparison with mature erythrocytes. In the thymus, HLA-negative, thymocyte antigen-positive cells (85%) can be distinguished from HLA-positive, thymocyte antigen-negative cells (15%). By using immunofluorescence techniques on tissue sections, the former cells were shown to be cortical thymocytes and the latter medullary cells.
Laser diode module for single-mode fiber based on new confocal combination lens method (1986)

A practical laser diode module is demonstrated for single-mode fiber applications. The module was developed through the use of a new combination lens method. The second lens in the confocal two-lens method is divided into two lenses. One is attached to the single-mode fiber front endface, thus forming a virtual fiber. Since both virtual fiber and lens misalignment tolerances are large in this coupling method, soldering is easily applicable. The laser diode module could be fabricated as easily as that for a multimode fiber. High coupling efficiency, excellent reproducibility, and high reliability were confirmed in trial-fabricated modules. Moreover, output power fluctuation due to reflected lightwaves was found to be very small.
Look-ahead traffic distribution in wormhole-routed networks (2002)

A new approach, look-ahead traffic distribution, is proposed in this paper to improve the performance of adaptive routing algorithms in wormhole routed networks. In most adaptive routing algorithms, a packet changes its forwarding direction only if its requesting channel is not available, i.e., the routing decision is based only on the traffic information (buffer availability) in adjacent nodes. The performance of these adaptive routing algorithms usually is far from optimal due to such a crude routing decision-making process without taking into consideration traffic information in non-adjacent nodes which a packet potentially is to be forwarded to at a later time. By adding minimal hardware to the router, the proposed approach allows neighboring routers to exchange integrated traffic information and each router to re-integrate information gathered before further propagation. It is intended to use a small amount of such integrated information to give each router a sketch of semi-global traffic information and degree of congestion in an extended local area. Such information is then used for a more intelligent routing decision-making process in each router. Experimental results show that the communication latency and the saturation point have been significantly improved by applying such an add-on feature to existing adaptive algorithms.
A New Trust Model Based on Social Characteristic and Reputation Mechanism for the Semantic Web (2008)

A serious problem on the WWW is finding reliable information. Not everything found on the Web is true and the semantic Web does not change that in any way. The problem will be even more crucial for the semantic Web, where agents will be integrating and using information from multiple sources. Statements published on the semantic Web have to be seen as claims rather than as facts, and there should be a way to decide which among many possibly inconsistent sources is most reliable. In this work, we propose a trust model for the semantic Web. The proposed model is inspired by the use trust in human society. Trust is a type of social knowledge and encodes evaluations about which agents can be taken as reliable sources of information or services. Our proposed model allows agents to decide which among different sources of information to trust and thus act rationally on the semantic Web.
Promotion Effect of Hydrogen on Vapor Phase Carbonylation of Methanol over Nickel on Active Carbon Catalyst (1987)

Abstract In the vapor phase carbonylation of methanol by carbon monoxide on a nickel on active carbon catalyst, co-existence of hydrogen greatly enhanced the rate of acetic acid production but with a slight increase in methane formation.
A vehicle detection approach based on multi-features fusion in the fisheye images (2011)

In a visual driver-assistance system, vehicle detection is one of the major tasks. This paper presents a vehicle detection method based on multi-features fusion in the images acquired by a fisheye camera. The vehicle detection algorithm can be divided into three main steps: fisheye image calibration, generation of candidates with respect to a vehicle and verification of the candidates. In the fist step, a fisheye image calibration algorithm based on cylinder model is proposed for reproducing virtual scene. The second step determines vehicle candidates using features such as the shadow, symmetry and vertical edge. A precise symmetry axis location approach is introduced by combining edge symmetry axis, grey-level symmetry axis and S-channel symmetry axis in HSV color space. Furthermore, a nighttime vehicle detection algorithm is designed by detecting the headlights. And the last step determines whether the candidate is a vehicle or not by using wavelet decomposition for feature extraction and the Support Vector Machines (SVMS) for classification. Experimental results in different conditions, including sunny, rainy, and nighttime demonstrates that most vehicles can be detected and recognized with a high accuracy and a frame rate of approximately 16 frames per second on a standard PC.
Ring oscillators response to irradiation and application to dosimetry (2009)

The response of ring oscillators to ionizing irradiation is investigated, regarding their possible use as dosimeters. Different structures were designed, fabricated and tested. Results show that dose resolution can be improved by one order of magnitude compared to conventional MOS dosimeters built in the same process.
Assembly of Nanoparticles at Liquid Interfaces: Crowding and Ordering (2014)

Experiments with the self-assembly of nanoparticles at liquid interfaces suggest that cooperative and slow dynamical processes due to particle crowding at the interface govern the adsorption and properties of the final assembly. Here we report a numerical approach to studying nonequilibrium adsorption, which elucidates these experimental observations. The analysis of particle rearrangements shows that local ordering processes are directly related to adsorption events at high interface coverage. Interestingly, this feature and the mechanism coupling local ordering to adsorption do not seem to change qualitatively upon increasing particle size polydispersity, although the latter changes the interface microstructure and its final properties. Our results indicate how adsorption kinetics can be used for the fabrication of 2D nanocomposites with controlled microstructure.
3D Multi-Cell Simulation of Tumor Growth and Angiogenesis (2009)

We present a 3D multi-cell simulation of a generic simplification of vascular tumor growth which can be easily extended and adapted to describe more specific vascular tumor types and host tissues. Initially, tumor cells proliferate as they take up the oxygen which the pre-existing vasculature supplies. The tumor grows exponentially. When the oxygen level drops below a threshold, the tumor cells become hypoxic and start secreting pro-angiogenic factors. At this stage, the tumor reaches a maximum diameter characteristic of an avascular tumor spheroid. The endothelial cells in the pre-existing vasculature respond to the pro-angiogenic factors both by chemotaxing towards higher concentrations of pro-angiogenic factors and by forming new blood vessels via angiogenesis. The tumor-induced vasculature increases the growth rate of the resulting vascularized solid tumor compared to an avascular tumor, allowing the tumor to grow beyond the spheroid in these linear-growth phases. First, in the linear-spherical phase of growth, the tumor remains spherical while its volume increases. Second, in the linear-cylindrical phase of growth the tumor elongates into a cylinder. Finally, in the linear-sheet phase of growth, tumor growth accelerates as the tumor changes from cylindrical to paddle-shaped. Substantial periods during which the tumor grows slowly or not at all separate the exponential from the linear-spherical and the linear-spherical from the linear-cylindrical growth phases. In contrast to other simulations in which avascular tumors remain spherical, our simulated avascular tumors form cylinders following the blood vessels, leading to a different distribution of hypoxic cells within the tumor. Our simulations cover time periods which are long enough to produce a range of biologically reasonable complex morphologies, allowing us to study how tumor-induced angiogenesis affects the growth rate, size and morphology of simulated tumors.
Biosynthesis of casein kinase II in lymphoid cell lines (1994)

We have analyzed the biosynthesis of casein kinase II. In exponentially growing tissue culture cells, the beta subunit was synthesized in excess of the catalytic subunit (alpha). A substantial fraction of newly synthesized beta was degraded within the first hour. The remaining fraction of beta was incorporated into holoenzyme. In contrast, little degradation of newly synthesized alpha subunit was observed and most was quickly and efficiently incorporated into holoenzyme. The assembly of beta with alpha was paralleled by an increase in apparent molecular mass of beta due to phosphorylation. The subcellular distribution of newly synthesized [35S]Met-labelled casein kinase II and of enzyme labelled and chased in the presence of excess unlabelled methionine was very similar and compatible with a nuclear localization. The degradation of the excess beta subunit occurred through a non-lysosomal proteolytic system with a very low ATP requirement.
Prostatic ischemia induces ventral prostatic hyperplasia in the SHR; possible mechanism of development of BPH (2014)

In the light of increasing evidence that benign prostatic hyperplasia is associated with cardiovascular disease, we have investigated the relationship between prostatic blood flow and prostatic hyperplasia in the spontaneously-hypertensive-rat (SHR). Twelve-week-old male SHRs were treated with nicorandil for six weeks. Wistar-Kyoto rats were used as controls. Six weeks after nicorandil treatment, blood pressure and the prostatic blood flow were estimated, and tissue levels of malondialdehyde, HIF-1α, TGF-β1, bFGF, dihydrotestosterone, and α-SMA were measured. SHRs showed significant increases in blood pressure, tissue levels of malondialdehyde, HIF-1α, TGF-β1, bFGF, α-SMA and a significant decrease in the prostatic blood flow. Although treatment with nicorandil failed to alter the blood-pressure and α-SMA, it significantly ameliorated the increased levels of malondialdehyde, HIF-1α, TGF-β1, and bFGF. There were no significant differences in tissue levels of dihydrotestosterone among any groups. These data indicate that development of prostatic hyperplasia may be associated with prostatic hypoxia, which nicorandil prevents via its effect to increase the blood flow.
SERUM PROTEINS, AMYLOID AND ALZHEIMER'S DISEASE* (1970)

A bstract Serum protein analysis in 60 patients with histologically confirmed Alzheimer's disease (Group A) and in 60 others with clinical dementia and radiographic evidence of diffuse cerebral atrophy compatible with Alzheimer's disease (Group B) revealed a decrease in albumin and an increase in alpha‐1 antitrypsin, alpha‐2 macroglobulin and haptoglobin fractions. These abnormalities occurred in 66 per cent of these two groups, but in only 13 per cent of a third group of patients with dementia of the non‐Alzheimer type. In addition, the highest values for alpha‐2 macroglobulin were found in Groups A and B. The possible relationships of these findings to amyloidosis of the central nervous system is discussed. The significance of these data may lie in their value as an aid in making the diagnosis of Alzheimer's disease in vivo, in the absence of a brain biopsy. Further study is needed to confirm these observations.

P3-S7.16 <i>Lactobacillus crispatus</i>colonisation reduces risk of Bacterial Vaginosis (BV) acquisition (2011)

Background Longitudinal studies have found that vaginal colonisation by hydrogen peroxide-producing strains of lactobacilli is associated with a reduced risk of BV acquisition. Several Lactobacillus spp. including L crispatus , L jensenii , and L gasseri can produce hydrogen peroxide, but no longitudinal studies to date have assessed whether all hydrogen peroxide producing species are equally protective. The objective of this study was to determine which species of Lactobacillus were associated with a reduced risk of BV acquisition. Methods In this secondary analysis of women enrolled in a vaccine trial, 112 women aged 18–40 who had Gram stain Nugent scores <6 at study entry were followed bimonthly for up to 18 months for acquisition of BV. Vaginal and rectal swabs were collected at each visit for culture identification of lactobacilli. Species identification was performed by repetitive sequence PCR, and if necessary, 16S rRNA gene RFLP or sequencing. Cox proportional hazards models were used to assess the association between Lactobacillus colonisation at the prior visit and BV acquisition. Results There were 40 BV acquisitions detected during 486 follow-up visits over 65.3 woman-years for an incidence of 61 per 100 woman-years. As shown in Abstract P3-S7.16 table 1, women colonised by L crispatus were 53% less likely to acquire BV at a subsequent visit (p=0.023). Abstract P3-S7.16 Table 1 Association between Lactobacillus colonisation in the vagina and acquisition of bacterial vaginosis (BV) Lactobacillus spp. # BV acquisitions per woman-years Rate Per 100 woman-years Unadjusted HR (95% CI) p Value L crispatus Present 14/35.5 39 0.47 (0.24 to 0.90) 0.023 Absent 26/29.8 87 L jensenii Present 18/22.6 80 1.42 (0.76 to 2.66) 0.270 Absent 22/42.7 52 L gasseri Present 11/16.1 68 1.08 (0.54 to 2.17) 0.820 Absent 29/49.3 59 L iners Present 13/20.2 64 1.13 (0.60 to 2.13) 0.695 Absent 27/45.1 60 Conclusions L crispatus was the only species protective against BV acquisition. Since neither L jensenii nor L gasseri reduced the risk of BV despite their capacity to produce hydrogen peroxide, other characteristics of L crispatus may be more critical then peroxide production in protecting from BV acquisition.

Cholesterol-Lowering Effects of Rice Bran and Rice Bran Oil Fractions in Hypercholesterolemic Hamsters (1992)

Cereal Chem. 69(5):485-489 The effects of temperature of extraction and fractionation of rice bran significantly lower plasma and liver cholesterol and triglycerides were oil were evaluated alone or in combination with defatted rice bran (DFB) observed in those fed an FFB diet than in those fed a CC diet. A diet to determine the effects on their cholesterol-lowering potential in hyper- consisting of DFB in combination with degummed-dewaxed rice bran cholesterolemic hamsters. Diets containing full-fat rice bran (FFB), DFB oil resulted in significantly lower liver cholesterol levels than did the CC plus rice bran oil (extracted at 4 or 540C), and 540C-extracted rice bran diet, whereas DFB alone, rice bran oil extracted at either temperature, oil fractions (gum, wax, and degummed-dewaxed oil) at levels found or DFB plus gum or wax fractions were not significantly different from in FFB were fed to 23-day-old hamsters. All diets contained 10% total the respective corn oil controls. Only FFB lowered both plasma and dietary fiber, 9% fat, and 3% nitrogen. After 21 days, liver weights and liver cholesterol in hamsters. The data suggest that some of the cholesterolplasma and liver cholesterol and plasma triglycerides were significantly lowering properties of FFB are present when DFB is recombined with higher in animals fed a diet of 0.3% cholesterol with cellulose (CC) than degummed-dewaxed rice bran oil, but some active components appear in animals fed a cholesterol-free cellulose diet. In cholesterol-fed hamsters, to be either lost or are deactivated in the fractionation process.
Householder response to the earned income tax credit: path of sustenance or road to asset building (2005)

This study seeks to gain a more complete picture about how the Earned Income Tax Credit program influences consumer expenditure and saving decisions. Based on survey data collected from over 18,000 taxpayers participating at the Volunteer Income Tax Assistance sites administered by the Community Food Resource Center, a nonprofit organization in New York City, we find that a fairly large proportion of lower-income taxpayers expect to use the majority of their refund for the purpose of paying debt and other more immediate expenses. Even so, almost 11 percent of these taxpayers reported that they would save a majority of their refund. ; The results from the empirical investigation determine that unbanked taxpayers are significantly more likely to open a low-cost savings account and that opening an account is positively related to the size of the refund. Evidence is also offered to show that nonprofit organizations can and do play an important role in helping to move lower income consumers into the financial mainstream and potentially facilitating asset-building behavior. This study helps inform policy by contributing to the growing body of literature about programs that encourage participation in the financial mainstream.
Multi-field nanoindentation apparatus for measuring local mechanical properties of materials in external magnetic and electric fields (2013)

Nano∕micro-scale mechanical properties of multiferroic materials can be controlled by the external magnetic or electric field due to the coupling interaction. For the first time, a modularized multi-field nanoindentation apparatus for carrying out testing on materials in external magnetostatic∕electrostatic field is constructed. Technical issues, such as the application of magnetic∕electric field and the processes to diminish the interference between external fields and the other parts of the apparatus, are addressed. Tests on calibration specimen indicate the feasibility of the apparatus. The load-displacement curves of ferromagnetic, ferroelectric, and magnetoelectric materials in the presence∕absence of external fields reveal the small-scale magnetomechanical and electromechanical coupling, showing as the ΔE and ΔHin effects, i.e., the magnetic∕electric field induced changes in the apparent elastic modulus and indentation hardness.
Dead time optimization method for power converter (2013)

Abstract. This paper introduces a method for dead time optimization in variable speed motor drive systems. The aim of this method is to reduce the conduction time of the freewheeling diode to a minimum without generation of cross conduction. This results in lower losses, improved EMC, and less overshooting of the phase voltage. The principle of the method is to detect beginning cross currents without adding additional components in the half bridge like resistors or inductances. Only the wave shape of the phase voltage needs to be monitored during switching. This is illustrated by an application of the method to a real power converter.

Enriching western coals by thermal drying and oil treatment (1976)

Lignite and subbituminous fuels in the western states have a much sought-after attribute--a low sulfur content that eases power station compliance with air-quality standards. Offsetting this advantage are high moisture and low Btu values. Commonwealth Edison Co., at its Pekin, Ill. steam-electric station, has taken steps to upgrade western coals. Removal of part of the water and further processing with an oil spray enriches the coal. The feasibility of enriching high-moisture, low-sulfur western coals depends upon the realization of several potential benefits: (1) lower transportation costs, both capital and expense; (2) delivering a coal with improved burning qualities; (3) reduction of operating and maintenance costs of boilers, and (4) an increase in boiler capability.
Van der Waals Complexes between Unsaturated Hydrocarbons and Boron Trifluoride:  An Infrared and <i>ab Initio</i> Study of Ethene·BF<sub>3</sub> and Propene·BF<sub>3</sub> (1997)

The mid-infrared (4000−400 cm-1) spectra of ethene/BF3 and propene/BF3 mixtures, dissolved in liquid argon (93−125K) and in liquid nitrogen (80−118K) are discussed. In all spectra, the formation of a 1:1 van der Waals complex, in which the electron deficient BF3 molecule binds to the CC double bond, was observed. Using spectra recorded at different temperatures, the complexation enthalpy ΔHo for ethene·BF3 was determined to be −10.0 ± 0.2 kJ mol-1 in liquid argon and −5.4 ± 0.3 kJ mol-1 in liquid nitrogen, while for propene·BF3 the ΔHo are −11.8 ± 0.2 and −6.9 ± 0.3 kJ mol-1, respectively. For both complexes a converged structure and the harmonic vibrational frequencies were calculated using ab initio calculations at the MP2/6-31+G* level.
