Suppression of delayed-type hypersensitivity to histocompatibility antigens by ultraviolet radiation. (1987)

Delayed-type hypersensitivity (DTH) reactions to allogeneic histocompatibility antigens in mice could be systemically suppressed by a single exposure to UV-B irradiation. The extent of suppression reached its maximum 4 days after irradiation, gradually waned thereafter, and disappeared at Day 21. Re-exposure of these mice to UV-B after waning reinduced the state of suppression. The suppression could be transferred to naive mice by means of splenic T lymphocytes. The suppressor T (Ts) cells suppressed the proliferative activity in the lymph nodes draining the site of immunization, but not the activity of already activated DTH-reactive T cells. Phenotypical analysis of these Ts cells revealed that two subpopulations of T cells are involved: one with the Lyt-1+, 2- phenotype, the other with the Lyt-1-, 2+ phenotype.
Comparison of microwave and thermal cure of epoxy–anhydride resins: Mechanical properties and dynamic characteristics (2005)

Abstract The objective of this work was to compare the mechanical properties of epoxy resins cured by thermal heating and microwave heating. Epoxy–anhydride (100:80) resins were cured in a domestic microwave oven and in a thermal oven. The hardening agents included methyl tetrahydrophthalic anhydride and methyl hexahydrophthalic anhydride. Three types of accelerators were employed. Thermal curing was performed at 150°C for 20 and 14 min for resins containing 1 and 4% accelerator, respectively. Microwave curing was carried out at a low power (207 or 276 W) for 10, 14, and 20 min. All cured resins were investigated with respect to their tensile properties, notched Izod impact resistance, and flexural properties (three‐point bending) according to ASTM standards. The tan δ and activation energy values were investigated with dynamic mechanical thermal analysis, and the extent of conversion was determined with differential scanning calorimetry. The differences in the mechanical properties of the thermally cured and microwave‐cured samples depended on the resin formulation and properties. Equivalent or better mechanical properties were obtained by microwave curing, in comparison with those obtained by thermal curing. Microwave curing also provided a shorter cure time and an equivalent degree of conversion. The glass‐transition temperatures (tan δ) of the thermally and microwave‐cured resins were comparable, and their activation energies were in the range of 327–521 kJ/mol. © 2005 Wiley Periodicals, Inc.

Cover and front matter (2000)

This is one part of the first comprehensive study of the development of Greek sculpture and painting with the aim of enriching the usual stylistic-sociological approaches through a serious, disciplined consideration of the basic Greek scientific orientation to the world.This world view, known as the Four Elements Theory, came to specific formulation at the same time as the perfected contrapposto of Polykleitos and a concern with the four root colors in painting (Polygnotos).All these factors are found to be intimately intertwined, for, at this stage of human culture, the spheres of science and art were not so drastically differentiated as in our era.The world of the four elements involved the concepts of polarity and complementarism at every level.One of the most important results of this approach, taken first mainly on the basis of an analysis of sculpture, is a deeper understanding of the conventional articulation of Greek art (and culture) into large characteristic periods.However, in order to understand the finer subdivisions of these periods, it was necessary to supplement the concern with the four elements as a dynamic system of macrocosmicmicrocosmic relationships with a study of the Greek conception of the mind, on the basis both of hints in ancient literature, mythology and art and of certain aspects of modern psychology.The result of this is a different kind of understanding than hitherto suggested for the motivating forces behind our conventional sub-periods.Other laborers in this field have been Bruno Snell and J. J. Pollitt.Essentially this book presents a new way of seeing Greek art through thought structures based on the work of the Greek natural philosophers themselves.Among these, Empedokles is at last accorded the commanding position he deserves to occupy for his contribution.
Relativistic astrophysics and cosmology (1998)

The Editorial Board of Classical and Quantum Gravity met recently to discuss the state of the journal and the subjects covered. They noted the vigour and vitality of the journal and how it is attracting a growing number of high quality submissions in theoretical and experimental gravity as well as numerical relativity. However, the Board thought that the number of articles in relativistic astrophysics and cosmology is not as as large as they would wish.
Bifunctional compounds based on transition metal mononitrosyl complexes combining photochromism and electric conductivity or photochromism and magnetism (2008)

This review summarizes mainly our findings concerning the synthesis, structure, and properties of molecular bifunctional compounds based on transition metal mononitrosyl complexes combining photochromism and electric conductivity or photochromism and magnetism. Organic π-donors capable of forming electroconducting radical cation salts or anionic magnetic metal complexes, including molecular nanomagnets, were used as the second functional block in the synthesis of bifunctional compounds.
A highly efficient, cell-free translation/translocation system prepared from<i>Xenopus</i>eggs (1991)

We describe the use of a Xenopus laevis egg extract for the in vitro translation and post translational modification of membrane and secretory proteins. This extract is capable of the translation and segregation into membranes of microgram per millilitre levels of protein from added mRNAs. Signal sequences of segregated proteins are efficiently cleaved and appropriate N-linked glycosylation patterns are produced. The extract also supports the quantitative assembly of murine immunoglobulin heavy and light chains into tetramers, and two events which take place beyond the endoplasmic reticulum, mannose 6 phosphorylation of murine cathepsin D and O-linked glycosylation of coronavirus E1 protein, also occur, but at reduced efficiency. The stability of the membranes allows protease protection studies and quantitative centrifugal fractionation of segregated and unsegregated proteins to be performed. Conditions for the use of stored extract have also been determined.
A Study on the Design of Cooling Channels of Injection Mould to Manufacture a Flat Part with a Partly Thick Volume (2012)

The shrinkage and the warpage of the moulded part are influenced by the design of the product and injection mould. In a flat part with a partly thick volume, the warpage of the flat part is created from the difference of the shrinkage between thin and thick regions. The warpage of the flat part with a partly thick volume can be reduced by a proper design of the cooling system in the injection mould. The goal of this paper is to design properly cooling channels of injection mould to manufacture a flat part with a partly thick volume. The conformal cooling channel is adopted to improve cooling characteristics of a region with the thick volume. The linear cooling channels are assigned to the other region. The proper design of the conformal cooling channels is obtained from three-dimensional injection molding analysis for various design alternatives. The moulding characteristics of the designed mould with both conformal and linear cooling channels are compared to those of the mould with linear cooling channels from viewpoints of temperature, shrinkage and warpage of the moulded part using numerical analysis. Injection mould with both conformal and linear cooling channels for the flat part with a partially thick volume is fabricated. In addition, injection moulding experiments are performed using the fabricated mould. From the results of the injection moulding experiments, it has been shown that the designed mould can successfully fabricate the flat part with a partially thick volume.
Thematic video thumbnail selection (2009)

Existing techniques to automatically create image thumbnail(s) for videos are mostly based on low-level feature analysis of the video frames, such as color and motion information. However, these approaches do not contain semantic models of the underlying theme of the video, and as a result, the selected frames may not be semantically representative. To address this problem, we propose a theme-based keyframe selection algorithm that explicitly models the visual characteristics of the underlying video theme. This thematic model is constructed by finding the common features of relevant visual samples, which are obtained by querying a visual database with keywords associated with the video. Our initial testing on a set of videos shows promising results of our video thumbnail image selection method.
Seismic Stratigraphy and Subsidence Analysis in the Barrow-Dampier Subbasin, Northwest Australia (1997)

The objective of this study is to analyze the basin-fill history of the Barrow-Dampier Subbasin (Northwest Shelf, Australia) as a spectacular and complex example of the stratigraphic record of continental breakup. From the Permian until the Holocene, the Barrow-Dampier Subbasin underwent development from a continental sedimentary basin located on the Gondwana continent to a rift graben. When extensional movement ceased, the subbasin developed as a passive continental margin. This study, based on marine seismic data (about 600 km) and logs of 20 wells, includes a seismic stratigraphic analysis tied to wells in the vicinity, chronostratigraphic charts, and the calculation of subsidence curves. The basin fill is characterized by a hierarchically organized architecture. The largest scale are four tectonic-stratigraphic units: prerift (Upper Permian to Pliensbachian), rift (until Callovian), postrift (until the Upper Cretaceous), and convergence (Neogene). The tectonostratigraphic units were built by 13 sequences of the time scale of second-order sequences. Several of the sequences coincide with discrete subsidence episodes on geohistory plots. For most sequences and sequence boundaries, either a eustatic or a tectonically enhanced origin could be established. A series of seismic facies maps for these sequences visualize the sedimentary basin evolution. Several of the second-order sequences can be subdivided into systems tracts or higher order sequences.
Smoke production and smoke reduction in endoscopic surgery: preliminary report. (1993)

This paper deals with the hazard of smoke production to patients undergoing endoscopic surgery. A study investigating methaemoglobin levels in a patient group operated on using smoke generating devices as compared to a control group yielded a significantly positive correlation between smoke production and methaemoglobin concentration. The mechanisms controlling methaemoglobin levels in the body and the specific toxic effect of elevated levels are dealt with. It is concluded that smoke production in endoscopic surgery is a factor of concern and should be minimized.
Improved neutron-gamma discrimination for a 6Li-glass neutron detector using digital signal analysis methods (2016)

A (6)Li-glass scintillator (GS20) based neutron Anger camera was developed for time-of-flight single-crystal diffraction instruments at Spallation Neutron Source. Traditional Pulse-Height Analysis (PHA) for Neutron-Gamma Discrimination (NGD) resulted in the neutron-gamma efficiency ratio (defined as NGD ratio) on the order of 10(4). The NGD ratios of Anger cameras need to be improved for broader applications including neutron reflectometers. For this purpose, six digital signal analysis methods of individual waveforms acquired from photomultiplier tubes were proposed using (i) charge integration, (ii) pulse-amplitude histograms, (iii) power spectrum analysis combined with the maximum pulse-amplitude, (iv) two event parameters (a1, b0) obtained from a Wiener filter, (v) an effective amplitude (m) obtained from an adaptive least-mean-square filter, and (vi) a cross-correlation coefficient between individual and reference waveforms. The NGD ratios are about 70 times those from the traditional PHA method. Our results indicate the NGD capabilities of neutron Anger cameras based on GS20 scintillators can be significantly improved with digital signal analysis methods.

Las Consideraciones sobre la funcionalidad de las glorietas recogen los textos legales vigentes en Espana de aplicacion al caso, con los objetivos de la red estatal de carreteras y los condicionantes establecidos por el legislador sobre la accesibilidad a nuevas carreteras, redes arteriales de poblaciones o grupos de poblaciones, y la explotacion de las carreteras estatales en suelo urbano, junto con las principales definiciones de una glorieta y su reglamentacion basica de circulacion en Espana. Entre los textos internacionales recogidos destacan las condiciones impuestas por el Acuerdo Europeo sobre las Grandes Carreteras de Trafico Internacional (AGR) de las Naciones Unidas y los criterios suplementarios que se barajan en la actualidad en la Union Europea como futuras caracteristicas de la red de carreteras transeuropeas (TERN). Se establece una jerarquia segun su funcion, entre las diferentes carreteras que constituyen un sistema vial; las caracteristicas funcionales propias de las glorietas, como tipo peculiar de solucion a nivel (interseccion) de un nudo de carreteras; y sus ventajas e inconvenientes, adecuacion o no y, en definitiva, idoneidad segun los diferentes casos. Como conclusion resulta que la glorieta es mas adecuada que otros tipos de interseccion por su seguridad de circulacion, capacidad, flexibilidad y coste de funcionamiento y comprension por parte de los usuarios. Puede ser una buena solucion para distribuir el trafico antes de una entrada o despues de una salida de una carretera de alta velocidad.
The Minimum Weight One-Dimensional Straight Cooling Fin (1974)

The Minimum Principle is used to obtain the minimum weight one-dimensional cooling fin without the length-of-arc assumption. This approach enlarges the class of optimum fin designs available for consideration. The heat-transfer coefficient and the, thermal conductivity can be temperature dependent. It is shown that the tip dimension vanishes for typical profiles. The results are specialized to make a comparison with results obtained with the length-of-arc assumption. With initial conditions obtained from the approximate method for kθ0/q0 = 10, the fin is 15 percent shorter than the classical parabolic profile and contains about 1.6 percent less material. The shorter fin length in this example and the flexibility in specifying the heat flux per unit fin base area for any fin are practical design considerations. The optimum fin is described by a nonlinear two-point boundary-value problem whose solution is obtained numerically. Computational guides are provided.
Hemorrhagic gastroesophageal ulceration by pulmonary infection in extrahepatic cholestatic pigs. (1994)

We developed a biliary and pulmonary microbiologic study in 22 Large-White pigs that underwent bile-duct ligation in order to demonstrate that sepsis has a biliary and pulmonary origin which may be involved in the gatroesophageal pathology. All the pigs died at 18.2 +/- 8.9 days of the post-operative period. The cause of death was hemorrhagic ulceration of the gastroesophageal region in 36.3% (n = 8) of the animals that also presented multiple bilateral miliary lung abscesses. High infestation rates with intestinal germs were found in the bile and lung. In conclusion, the experimental model of extrahepatic cholestasis in the Large-White pig could be useful for the study of etiopathogenic mechanisms by which the pulmonary infection produces a hemorrhagic gastroesophageal ulceration considered as stress ulcer.
Pebl:web page classification without negative examples (2004)

Web page classification is one of the essential techniques for Web mining because classifying Web pages of an interesting class is often the first step of mining the Web. However, constructing a classifier for an interesting class requires laborious preprocessing such as collecting positive and negative training examples. For instance, in order to construct a "homepage" classifier, one needs to collect a sample of homepages (positive examples) and a sample of nonhomepages (negative examples). In particular, collecting negative training examples requires arduous work and caution to avoid bias. The paper presents a framework, called positive example based learning (PEBL), for Web page classification which eliminates the need for manually collecting negative training examples in preprocessing. The PEBL framework applies an algorithm, called mapping-convergence (M-C), to achieve high classification accuracy (with positive and unlabeled data) as high as that of a traditional SVM (with positive and negative data). M-C runs in two stages: the mapping stage and convergence stage. In the mapping stage, the algorithm uses a weak classifier that draws an initial approximation of "strong" negative data. Based on the initial approximation, the convergence stage iteratively runs an internal classifier (e.g., SVM) which maximizes margins to progressively improve the approximation of negative data. Thus, the class boundary eventually converges to the true boundary of the positive class in the feature space. We present the M-C algorithm with supporting theoretical and experimental justifications. Our experiments show that, given the same set of positive examples; the M-C algorithm outperforms one-class SVMs, and it is almost as accurate as the traditional SVMs.
Repression by SSN6-TUP1 is directed by MIG1, a repressor/activator protein. (1995)

The SSN6-TUP1 protein complex represses transcription of diversely regulated genes in the yeast Saccharomyces cerevisiae. Here we present evidence that MIG1, a zinc-finger protein in the EGR1/Zif268 family, recruits SSN6-TUP1 to glucose-repressed promoters. DNA-bound LexA-MIG1 represses transcription of a target gene in glucose-grown cells, and repression requires SSN6 and TUP1. We also show that MIG1 and SSN6 fusion proteins interact in the two-hybrid system. Unexpectedly, we found that LexA-MIG1 activates transcription strongly in an ssn6 mutant and weakly in a tup1 mutant. Finally, LexA-MIG1 does not repress transcription in glucose-deprived cells, and MIG1 is differentially phosphorylated in response to glucose availability. We suggest a role for phosphorylation in regulating repression.
The combination of intravenous bevacizumab and metronomic oral cyclophosphamide is an effective regimen for platinum-resistant recurrent ovarian cancer (2013)

Bevacizumab and cyclophosphamide is an effective, well-tolerated chemotherapy regimen in heavily pretreated patients with recurrent ovarian carcinoma. This combination significantly improved PFS and OS in responders. Response rates were similar and favorable to the rates reported for similar patients receiving other commonly used second-line chemotherapeutic agents.
Improvement of SOS Device Performance by Solid-Phase Epitaxy (1982)

Crystalline quality in the whole region of silicon film on sapphire substrate has been improved by doubly applying solid-phase epitaxial regrowth combined with amorphization of both the silicon surface and the silicon-sapphire interface regions of SOS. Observations, by Rutherford backscattering and chemical delineation, indicate that planar defect density in the film becomes less than 1/100 of that in an as-grown film. Effective mobilities of n- and p-channel FETs in the improved film are 520 and 225 cm 2 /V·s, which are 1.3 times and 1.1 times larger than those in the as-grown film, respectively. A significantly reduced drain leakage current of 1.8×10 12 A/50 µm for n-channel FET is obtained, whose value is about 1/100 of those in as-grown samples. The higher mobility and lower leakage current thus obtained, should be attributed to the drastic improvement of crystalline quality in the whole region of SOS by the double solid-phase epitaxy.

Interface studies of tungsten nitride and titanium nitride composite metal gate electrodes with thin dielectric layers (1998)

Interface formation between reactively sputtered tungsten nitride (WNx) or titanium nitride (TiNx) metallic films and thermally grown silicon dioxide (SiO2) layers is studied by interrupted growth with on-line Auger electron spectroscopy. For both composite metals, growth proceeds directly without a metal precursor layer. The chemical stability of these WNx/SiO2 and TiNx/SiO2 interfaces is investigated by rapid thermal annealing up to 850 °C. The WNx/SiO2 interface is stable up to 650 °C while TiNx/SiO2 is stable below 850 °C. Metal–oxide–semiconductor capacitors have been fabricated with WNx and TiNx gates and 7.5 nm thick thermal oxide gate dielectrics with interface trap densities, Dit&lt;2×1011 cm−2 eV−1. Capacitance–voltage and current–voltage measurements indicate the Fermi level for TiNx lies near midgap in Si, while for WNx it lies closer to the valence band.
BACI debugger: a GUI debugger for the BACI system (2002)

Due to the increasing importance of concurrent programming and distributed computing systems, possessing a good understanding of concurrency and its impact on process synchronization is essential. Since concurrency introduces design and execution issues not found in sequential programming, to learn about concurrency issues, it is important that students gain hands on experience actually doing concurrent programming. The best way to get this experience is by using a system developed specifically for teaching concurrent programming. The Ben-Ari Concurrent Interpreter (BACI) is such a system. Unfortunately, when errors are encountered in BACI programs, they are cumbersome to debug. The purpose of this paper is to introduce and describe a Java-based graphical user interface debugger for the BACI language.
