Existing file access predictors keep track of previous file access patterns and rely on a single heuristic to predict which of the previous successors to the file being currently accessed is the most likely to be accessed next. We present here a novel composite predictor that applies multiple heuristics to this selection problem. As a result, it can make use of specialized heuristics that can m...

Tetrodotoxin-resistant (TTX-R) Na(+) channels are 1,000-fold less sensitive to TTX than TTX-sensitive (TTX-S) Na(+) channels. On the other hand, TTX-R channels are much more susceptible to external Cd(2+) block than TTX-S channels. A cysteine (or serine) residue situated just next to the aspartate residue of the presumable selectivity filter "DEKA" ring of the TTX-R channel has been identified ...

Types of files (text, executables, Jpeg images, etc.) can be identified through file extension, magic number, or other header information in the file. However, they are easy to be tampered or corrupted so cannot be trusted as secure ways to identify file types.In the presence of adversaries, analyzing the file content may be a more reliable way to identify file types, but existing approaches of...
