In H.264 video compression standard, B frame bi-directional predictions and its DIRECT mode coding are included to enhance video compression efficiency. However, such tools require a complex mode decision process and result in a long computation time. Therefore, fast algorithms are crucial in implementing H.264. In this paper, to save B frame encoding time, a fast DIRECT mode prediction algorit...

plasma membrane h+-atpase is a major integral membrane protein with a role in various physiological processes including abiotic stress response. to study the effect of nacl on the expression pattern of a gene encoding the plasma membrane h+-atpase, an experiment was carried out in a completely random design with three replications. a pair of specific primers was designed based on the sequence o...

Background:Isolates of Staphylococcus aureus express a myriad of adhesive surface proteins that play important role in colonization of the bacteria on nasal and skin surfaces, beginning the process of pathogenesis. The aim of this study was to screen several of the Microbial Surface Components Recognizing Adhesive Matrix Molecules (MSCRAMMs) genes among the isolate of S. a...
