A theoretical study of the response of hole mobility and thermal velocity, both relevant for short channel devices, to [110] uniaxial stress in Si up to 4 GPa of both tension and compression has been conducted. The strained-Si bandstructure was calculated using the kmiddotp method. Effective masses, thermal velocities, and scattering rates were calculated from the bandstructure as a function of stress. Mobilities were then calculated via full band Monte Carlo simulations. Calculated mobilities match experimental and theoretical data from prior work addressing lower degrees of stress. Large increases in both carrier thermal velocities and mobilities were found. In the high-stress regime between 1 and 2 GPa, mobilities exhibit a strong superlinear dependence, and compressive stress becomes more favorable for increasing both mobilities and thermal velocities in pMOS. Improvements in both thermal velocity and mobility finally only begin to rolloff toward apparent saturation as we push the stress toward 4 GPa in these simulations 相似文献

Pre-mixing oxygen with the fuel of diffusion flames markedly increases the level of soot formation, the effect being most pronounced with unsaturated and aromatic hydrocarbons and least with saturated ones. With ethylene, almost five times as much soot is obtained when 10% of the stoichiometric oxygen requirements of the flame is added to the fuel. Larger amounts completely suppress soot emission. The experimental evidence suggests that the role of the oxygen at low concentrations is to promote polymerization of the fuel to high-molecular-weight soot precursors, rather than a thermal effect. After 10 to 15% of the stoichiometric oxygen requirements have been pre-mixed with the fuel, carbon emission is abruptly eliminated over a narrow range of oxygen concentrations. This must be brought about by an oxidation of the fuel or of the potential carbon-forming intermediate which predominates at the higher oxygen concentrations. Dilution of the oxygen with inert gases such as nitrogen, argon and helium reduces its effectiveness to promote the formation of carbon, and appears to be a concentration effect, a conclusion in full agreement with the well known observation that higher pressures lead to increased soot formation. Other free-radical generators such as nitropropane and amyl nitrite also promote soot formation. 相似文献

We describe a new parallel algorithm for computing the generalized singular value decomposition of two n × n matrices, one of which is nonsingular. Our procedure requires O(n) time and one triangular array of O(n2) processors. 相似文献

The BEACOPP (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, and prednisone) regimen, a rearranged and accelerated version of the standard COPP/adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy, has been shown to be effective and safe in a previous pilot study for advanced stage Hodgkin's disease (HD). The present study aimed to determine a maximum practicable dose of three drugs, ie, etoposide, adriamycin, and cyclophosphamide, for which acute toxicities were acceptable and to assess the feasibility of the escalated scheme. Sixty untreated patients with advanced stage HD were enrolled in this study. Radiotherapy was given in 44 patients (73%) after chemotherapy to initial bulk lesions and residual disease. Granulocyte-colony stimulating factor (G-CSF) was given from day 8 to prevent prolonged neutrocytopenia and severe infections. The intended doses of adriamycin, etoposide, and cyclophosphamide in the BEACOPP schedule could be substantially escalated: adriamycin from 25 to 35, cyclophosphamide from 650 to 1,200, and etoposide from 100 to 200 mg/m2. The major toxicities were leukocytopenia and thrombocytopenia with considerable heterogeneity between individual patients. Of 60 patients, 56 (93%) achieved a complete remission (CR). At a median observation of 32 months, the rates of survival and freedom from treatment failure (FFTF) were estimated to be 91% (95% confidence interval 83% to 99%) and 90% (82% to 98%). These results show that a moderate dose escalation of adriamycin, cyclophosphamide, and etoposide of the baseline BEACOPP regimen is feasible. The escalated BEACOPP regimen shows very encouraging results in advanced stage HD and is now being compared in a randomized phase III study with BEACOPP at baseline dose level. 相似文献

This paper considers some software and technical issues involved in the production of high quality three dimensional business graphics. It considers whether to use the vector or raster mode, the location or generation of source materials such as type fonts and geographic maps, existing 3-D plotting programs, and some technical issues in the calculation of 3-D plots. Finally it gives some examples of 3-D color plots illustrating different color techniques. 相似文献

The excretion and plasma concentrations of radioactivity and chromatographic patterns of radioactive components in plasma and excreta have been compared in rats, dogs and man after oral doses of the hypolipidemic agent isopropyl-[4'-(p-chlorobenzoyl)-2-phenoxy-2-methyl]-propionate (LF 178; procetofene; Lipanthyl?). 2. In rats, 48.1% of a single dose of 25 mg/kg was excreted in the urine, and 48.6% in the faeces. In dogs, 23.1% of a single dose at the same level was excreted in the urine, and 71.8% in the faeces, but 88.1% of a dose of 300 mg to man was excreted in the urine, and only 5.1% in the faeces. Peak levels of radioactivity in the plasma of all three species studied were similar (20--30 mug/ml) after doses at these levels and concentrations declined thereafter with half-lives of 7--24 h in rats and dogs, and 7 h in man. The half-life of radioactivity concentrations in rat plasma was not altered by repeated daily doses for 7 days. 3. Whole-body autoradiography of rats showed that radioactivity was largely associated with the liver, kidneys and gut, which are the organs of biotransformation and excretion, although relatively high levels were present in lungs and blood, and small amounts of radioactivity had a widespread distribution into some peripheral tissues during 2--7 h after dosing. 4. The available chromatographic evidence indicated that the most important biotransformation pathway appeared to be ester hydrolysis to LF 178 acid and formation of water soluble conjugates of this acid. This pathway appeared similar to that of the related drug clofibrate (ethyl p-chlorophenoxyisobutyrate). 相似文献
