chemokine and chemokine receptors show several variations which may affect resistance to infectious disease. a 32 base pair deletion in the open reading frame of the human ccr5 gene (ccr5?32) results in producing a truncated antigen which fails to be presented on the surface of target cells. ccr5?32 variant is not a functional co receptor for hiv-1 entrance and delay the onset of acquired immun...

Steganography embeds a secret message in a seemingly innocuous cover-object. This paper presents a framework for steganography with executables as cover-objects built on top of an existing binary rewriter. Executables differ significantly from previously explored coverobjects, we thus first identify the cover-specific redundancies that can be used to embed a secret message. Techniques are then ...

The sensitivity of monolayers of Ilford L-4 nuclear emulsion to beta(-)-particles is approximately 0.20 grain per particle emitted for H(3), and 0.025 grain per particle for p(32). The sensitivity for thick layers is 1.3 grains per tritium beta(-)-particle emitted within the emulsion. In electron microscopic autoradiographs the maximum resolution is approximately 0.1 micron for H(3) and 0.3 mic...
