Who'll sweep the Gene Sweepstake?

The dual of sweep

As an in nite union operation sweep of a moving object through space is a powerful and natural addition to the Boolean set operations that incorporates motion related information for the purposes of shaping collision detection and simulation of moving objects Use of sweep has been hindered by limited computational support and by the fact that it is a material growing operation whereas many appl...

Implicit Sweep

Mark DURING Sweep rather than Mark THEN Sweep

Garbage Collection frees the programmer from the burden of explicitly deallocating unused data. This facility induces a considerable overhead but also causes some delays that may aaect real-time applications. Guaranteed throughput (with at most short and predictable delays) is needed in many applications such as plane or plant control and requires at least a worst case analysis to identify the ...

Hard Selective Sweep and Ectopic Gene Conversion in a Gene Cluster Affording Environmental Adaptation

Among the rare colonizers of heavy-metal rich toxic soils, Arabidopsis halleri is a compelling model extremophile, physiologically distinct from its sister species A. lyrata, and A. thaliana. Naturally selected metal hypertolerance and extraordinarily high leaf metal accumulation in A. halleri both require Heavy Metal ATPase4 (HMA4) encoding a PIB-type ATPase that pumps Zn(2+) and Cd(2+) out of...

The power of the feed-forward sweep

Vision is fast and efficient. A novel natural scene can be categorized (e.g. does it contain an animal, a vehicle?) by human observers in less than 150 ms, and with minimal attentional resources. This ability still holds under strong backward masking conditions. In fact, with a stimulus onset asynchrony of about 30 ms (the time between the scene and mask onset), the first 30 ms of selective beh...
