Asynchronous circuits are increasingly proposed as an efficient circuit-level solution for Process Variability. Asynchronous circuits are self timed, which gives them the opportunity to be immune against all variability sources including process-variability. Moreover, asynchronous circuits gain interesting properties due to variability in terms of performance and power-consumption distribution....

background: the tan spot disease of wheat caused by pyrenophera tritici-repentis has become a major disease in most wheat growing areas worldwide. objectives: here we used issr and rapd markers to study the genetic diversity of 34 p. tritici-repentis isolates collected from north of iran.materials and methods: the leaves having the typical symptoms of tan spot disease were collected and after f...
