Members of the spalt (sal) gene family encode zinc-finger proteins that are putative tumor suppressors and regulate anteroposterior (AP) patterning, cellular identity, and, possibly, cell cycle progression. The mechanism through which sal genes carry out these functions is unclear. The Caenorhabditis elegans sal gene sem-4 controls the fate of several different cell types, including neurons, mu...

Distributed shared memoy (DSM) systems have attracted considembie research efforts recently, since they combine the advantages of two different computer classes: shared memory multiprocessors and distn’buted systems. The most important one is the use of shared memory programming pamdigm on physically distributed memon.es. In the first part of this paper, one possible classiJication taxonomy, wh...

Reconfigurable optical interconnects can revive large-scale shared-memory processing.

Advances in microscopy and fluorescent reporters have allowed us to detect the onset of gene expression on a cell-by-cell basis in a systemic fashion. This information, however, is often encoded in large repositories of images, and developing ways to extract this spatiotemporal expression data is a difficult problem that often uses complex domain-specific methods for each individual data set. W...
