Self testing and fault secure XOR/XNOR circuit using FinFETs

Abstract: In the field of industrial application self checking designs have been playing a vital role as they appear to be providing high fault coverage with less risk. A Fin FET based self checking XOR/XNOR circuit is introduced that provide fault secure and self-testing applications. The design since proposed is simulated using Cadence spectre FinFET 20nm technology at various supply voltages associating from +0.3V to +0.6V. The simulation results indicate that the design proposed has code disjoint, fault secure and self-testing features and display less delay and power consumption. This design has a full voltage swing at the outputs hence it has the good driving capability. The proposed design produces perfect outputs for valid inputs and invalid outputs for invalid inputs.

Molecular phylogeny and evolution of Pulmonata (Mollusca: Gastropoda) on the basis of mitochondrial (16S, COI) and nuclear markers (18S, 28S): an overview

Abstract: The phylogenetic relationships among the major groups of Pulmonata were studied by the information derived from a concatenated dataset consisting of mitochondrial (16S and COI) and nuclear (18S and 28S) markers. Heterobranchia are recovered as monophyletic. Euthyneura as paraphyletic due to the emergence of taxa from Opisthobranchia and lower Heterobranchia. The major groups of Pulmonata, namely Stylommatophora, Veronicellidae, Onchidiidae, Otinoidea, Siphonarioidea and Hygrophila are recovered as monophyletic. Monophyly of Basommatophora was not confirmed due to the variable position of Siphonarioidea and Amphiboloidea. Evolutionary divergence times for different taxa were also estimated using a relaxed molecular clock method in Bayesian evolutionary analysis by sampling trees (BEAST). The common ancestor of Heterobranchia and Caenogastropoda was originated in the Silurian period and the common ancestors of Euthyneura and Pulmonata were originated in the Carboniferous and lower Triassic periods, respectively.
