it has been well - established that common atrial flutter is due to intraatrial macroreentry and its reentry circuit locates in the right atrium. this reentry circuit has been characterized to involve an area of slow conduction identifiable electrophysiologically at the low posteroseptal right atrium and anatomical narrow isthmus snrrounded by the inferior vena capa, coronary sinus astium and t...

Circuit-level implementation of a novel neuron has been discussed in this article. A low-power Activation Function (AF) circuit is introduced in this paper, which is then combined with a highly linear synapse circuit to form the neuron architecture. Designed in Carbon Nanotube Field-Effect Transistor (CNTFET) technology, the proposed structure consumes low power, which makes it suitable for the...

Various synthesis methods have been proposed in the literature for reversible and quantum logic circuits. However, there are few algorithms to optimize an existing circuit with multiple constraints simultaneously. In this paper, some heuristics in genetic algorithms (GA) to optimize a given circuit in terms of quantum cost, number of gates, location of garbage outputs, and delay, are proposed. ...

Abstract— In this paper, input impedance of a vertical rod under lightning stroke is first computed by applying the method of moments (MoM) on the Maxwell’s equations. The circuit model is then achieved through applying modified vector fitting (MVF) on the computed input impedance. After then the equivalent circuit is again extracted for a few values of soil conductivity and rod radius. Finally...

Nucleic acid circuits are finding increasing real-life applications in diagnostics and synthetic biology. Although DNA has been the main operator in most nucleic acid circuits, transcriptionally produced RNA circuits could provide powerful alternatives for reagent production and their use in cells. Towards these goals, we have implemented a particular nucleic acid circuit, catalytic hairpin ass...

The ability of pathogens to cope with disparate environmental stresses is a crucial feature for bacterial survival and for the establishment of a successful infection and colonization of the host; in this respect, chaperones and heat shock proteins (HSPs) play a fundamental role in host-pathogen interactions. In Helicobacter pylori, the expression of the major HSPs is tightly regulated through ...
