CONTEXT Despite widespread use of serum prostate-specific antigen (PSA) testing to detect prostate cancer, the relative effectiveness of different PSA screening strategies is unknown. OBJECTIVE To compare prostate cancer mortality, PSA testing rates, and biopsy rates using various PSA screening strategies, including the standard strategy of annually testing men aged 50 through 75 years. DES...

Due to increase in web-based applications, the need for enhanced information retrieval system that accommodate user’s needs become crucial. Most of commercial information retrieval system are based on standard Boolean model and at less scale vector models. Although the deficiencies of these models are now part of text-book knowledge, the development of new models still have to overcome the feas...

Decision makers need confidence that the models and simulations they use are fit to support their decision making process, such that their decisions are useful to their specific project or program. It is entirely possible and even quite likely, that individual models and simulations or those expressly for federate use are already available somewhere in the world. Users of these models, simulati...

introduction: multi-drug resistant (mdr) p. aeruginosa is constantly increasing and causing severe issues in combatting widely spread health problems. the aim of this study was to assess colistin susceptibility in mdr p. aeruginosa isolates obtained from different infection sites. methods: ninety clinical isolates of p. aeruginosa were collected from different hospitals of the tabriz university...

The role of charm in testing the Standard Model description of quark mixing and CP violation through measurements of lifetimes, decay constants and semileptonic form factors is reviewed. Together with Lattice QCD, charm has the potential this decade to maximize the sensitivity of the entire flavor physics program to new physics. and pave the way for understanding physics beyond the Standard Mod...
