The pathogen Vibrio cholerae uses cations as a primary currency of virulence
and environmental persistence, using gradients of those cations to move, acquire
nutrients, and control virulence gene expression. An understanding of the overlapping
roles of bioenergetics and chemotaxis in the virulence and environmental survival of
V. cholerae issues from...
"‘Biometrics is at the forefront in our agenda for homeland security,’ declared Asa Hutchinson, the Department of Homeland Security's undersecretary for border and transportation security, at the 2004 Biometric Consortium Conference” .
Flashy retinal scanning and voice activated computers were once considered technologies for science fiction movies and novels. Nowadays,...
There is a software gap in parallel processing. The short lifespan and small installation base of parallel architectures have made it economically infeasible to develop platform-specific parallel programming environments that deliver performance and programmability. One obvious solution is to build architecture-independent programming environments. But the architecture independence usually comes at...
Programming parallel machines has been a difficult and unrewarding task. The short lifespan
of parallel machines and their incompatibility have made it difficult to utilize them. Our goal
here is to create an environment for parallel computing which allows users to take advantage
of parallel computers without writing parallel programs....
Existing parallel file systems are proving inadequate in two important arenas:
programmability and performance. Both of these inadequacies can largely be traced
to the fact that nearly all parallel file systems evolved from Unix and rely on a Unix-oriented,
single-stream, block-at-a-time approach to file I/O. This one-size-fits-all
approach to parallel...
The Permian rocks near Quinn River Crossing, Humboldt County,
Nevada, crop out as a north-trending block-faulted ridge and consist
of more than 2600 feet of middle Permian fossiliferous limestone.
About 1000 feet of unfossiliferous cherty shales, sandstones, and
conglomerates are associated with the limestone and are assumed also
