Observations were made on an isolated hind leg preparation of dogs, perfused with blood and various homogeneous perfusates. A wide range of intravascular pressures were used while a constant arteriovenous pressure gradient was maintained. It was found that parallel increases in arterial and venous pressures result in a reduction in resistance to blood flow. A similar change in resistance is obs...

OBJECTIVES To compare genotypic and phenotypic HIV-1 drug resistance assays. METHODS Protease inhibitor (PI) susceptibility was phenotypically analysed in HIV-1 isolates and recombinant viruses expressing proteases from viral isolates. Two genotypic interpretation methods were carried out in parallel. RESULTS Entirely concordant resistance levels were shown in 5/10 (50%) highly active anti-...

Seventy-two men with gonococcal urethritis were given a single 300-mg dose of minocycline. The failure rate was 13% and the trial was terminated at an early stage. Failure was correlated with increased resistance of Neisseria gonorrhoeae to minocycline. The activity of penicillin, spectinomycin, erythromycin, tetracycline, sulphamethoxazole, cefuroxime, cefotaxime, rosamicin, thiamphenicol, and...

Resistive memories store information in a crossbar arrangement of two-terminal devices that can be programmed to patterns high or low resistance. While extremely compact, this technology suffers from the "sneak-path" problem: certain cannot recovered, as multiple resistances parallel make resistance indistinguishable In paper, multi-layer device is considered, and number bits it derived exactly...

Alternating current measurements of the effective capacity and resistance of Valonia cells were undertaken to determine whether a static or polarization capacity was responsible for the large slow time curves of counter E.M.F. produced by the flow of direct current. (For this purpose it was necessary that the cells be in the regular state.) With external contacts at the ends of ceils, a large f...

ParLeda is a software library that provides the basic primitives needed for parallel implementation of computational geometry applications. It can also be used in implementing a parallel application that uses geometric data structures. The parallel model that we use is based on a new heterogeneous parallel model named HBSP, which is based on BSP and is introduced here. ParLeda uses two main lib...
