background: patients with bleeding disorders are frequently infected with hepatitis c virus (hcv). there are few reports on the effect of standard interferon in these patients and no published report on pegylated interferon. the aim of this study was to compare pegylated interferon alpha-2a and standard interferon alpha with ribavirin in patients with bleeding disorders and chronic hcv infectio...

This article discusses algorithms for scheduling task graphs G V E to LogP machines These algorithms depend on the granularity of G i e on the ratio of computation v and communication times in the LogP cost model and on the structure of G We de ne a class of coarse grained task graphs that can be scheduled with a performance guarantee of Topt G where Topt G is the time required for the optimal ...

We parallelize the ‘Go with the winners’ algorithm of Aldous and Vazirani [1] and analyze the resulting parallel algorithm in the LogP-model [4]. The main issues in the analysis are load imbalances and communication delays. The result of the analysis is a practical algorithm which, under reasonable assumptions, achieves linear speedup. Finally, we analyze our algorithm for a concrete applicatio...

Organic cation transporters play a critical role in the elimination of therapeutic compounds in the liver and the kidney. We used computational quantitative structure activity approaches to predict molecular features that influence interaction with the human ortholog of the organic cation transporter (hOCT1). [(3)H]tetraethylammonium uptake in HeLa cells stably expressing hOCT1 was inhibited to...

This work describes an apparatus which can be used to vary communication performance parameters for MPI applications, and provides a tool to analyze the impact of communication performance on parallel applications. Our tool is based on Myrinet (along with GM). We use an extension of the LogP model to allow greater flexibility in determining the parameter(s) to which parallel applications may be...

the present research has been carried out to study the structure of indexing language databases of irandoc. three databases have been selected as a sample: iranian dissertation abstracts. directory of scientific meetings held in iran. current research in iranian universities and research centers. some descriptors have been selected as a sample for study. to analyze the descriptors checklist was...

In this work the structural requirements of both urea and thiourea derivatives were evaluated for optimal antibacterial activity on Staphylococcus aureus, Klebsiella pneumoniae and Escherichia coli, using several organic compounds (VI-X) as chemical tools. In order to delineate the structural chemical requirements of studied compounds, the descriptors Log P, π MR and MV were calculated. The res...

We present a systematic performance assessment of the hardware and software that provides the interface between applications and emerging high-speed networks. Using LogP as a conceptual framework and Active Messages as the communication layer, we devise a set of communication microbenchmarks. These generate a graphical signature from which we extract the LogP performance parameters of latency, ...
