Evc is essential for Indian Hedgehog (Hh) signalling in the cartilage growth plate. The gene encoding Evc2 is in close proximity in divergent orientation to Evc and mutations in both human genes lead to the chondrodysplasia Ellis-van Creveld syndrome. Bioinformatic analysis reveals that the Evc and Evc2 genes arose through a duplication event early in(More)
Hardware designers are constantly working to improve circuit performance in an attempt to outdo their competitors and satisfy consumers. Throughput is the average number of instructions that can be processed by a microprocessor in a given time. Pipelining is an optimization technique used ubiquitously for improving circuit throughput. We describe an(More)
