Salmonella Typhimurium was isolated from two adult cows and a veterinary pathologist who performed a necropsy examination on one of the cows. The isolates had indistinguishable phenotypic and genotypic characteristics. A splash exposure was the suspected means of transmission of the human infection. Veterinary practices and other at-risk occupations should establish site-specific infection cont...

Noninteractive zero-knowledge proofs and noninteractive witness-indistinguishable proofs have played a significant role in the theory of cryptography. However, lack of efficiency has prevented them from being used in practice. One of the roots of this inefficiency is that noninteractive zero-knowledge proofs have been constructed for general NP-complete languages such as Circuit Satisfiability,...

A long and intense debate in philosophy is concerned with the question whether there can be haecceistic differences between possible worlds, that is, nonqualitative only arise from different de re representations. According to haecceitism, it give rise a situation if positions of two qualitatively identical particles are exchanged, while according anti-haecceitism, this not case. It has been su...
