Snails are widely assumed to be slow animals. Yet the literature on sluggish speed is surprisingly limited, and only few have actually bothered to measure and record it formally. Further, reported gastropod speeds vary widely with species and circumstance, ranging from 0.000023 to 0.0028 meters per second ([1] and [2], respectively). With that in mind, it is not surprising that the use of snail...

This paper shows that self-timed meshes can achieve linear speed-up. The per-processor performance of a mesh is the average number of operations per processor per unit time. For synchronous processors, it has been shown that the per-processor performance of a mesh goes to zero as the size of the mesh goes to injnity. This paper shows that for self-timed meshes, the per-processor performance can...

Recent studies have revealed a distinct class of bacterial effectors defined by the presence of EPIYA or EPIYA-related motif. These bacterial EPIYA effectors are delivered into host cells via type III or IV secretion, where they undergo tyrosine phosphorylation at the EPIYA motif and thereby manipulate host signalling by promiscuously interacting with multiple SH2 domain-containing proteins. Up...
