It is generally believed that after memory consolidation, memory-encoding synaptic circuits are persistently modified and become less plastic. This, however, may hinder the remaining capacity of information storage in a given neural circuit. Here we consider the hypothesis that memory-encoding synaptic circuits still retain reversible plasticity even after memory consolidation. To test this, we...

Quantum and reversible logic circuits have more advantages than the common circuits, like low power consumption. These circuits are good choice to design future computers. One of the important issues in reversible logic is parity preservation. If parity of inputs and outputs are equal in reversible gate, this gate will be parity preserve. Reversible circuits made by these gates are parity prese...

Reversible logic has come to the forefront of theoretical and applied research today. Although many researchers are investigating techniques to synthesize reversible combinational logic, there is little work in the area of sequential reversible logic. Latches and flip-flops are the most significant memory elements for the forthcoming sequential memory elements. In this paper, we proposed two ne...

we introduce the notion ofstrongly $alpha$-reversible rings which is a strong version of$alpha$-reversible rings, and investigate its properties. we firstgive an example to show that strongly reversible rings need not bestrongly $alpha$-reversible. we next argue about the strong$alpha$-reversibility of some kinds of extensions. a number ofproperties of this version are established. it is shown ...

Reversible logic circuits have found emerging attention in nanotechnology, quantum computing and low power CMOS designs. In this paper we present a modular synthesis method to realize a reversible Binary Coded Decimal (BCD) adder/subtractor circuit. We use genetic algorithms and don’t care concept to design and optimize all parts of a BCD adder circuit in terms of number of garbage inputs/outpu...

Modern digital circuit designing is now focussing on the reversible circuits. It aims towards the designing of low power loss circuits in the area of nanotechnology, quantum computing, optical computing, signal processing etc. This paper presents an optimized two-bit binary comparator based on reversible logic using Feynman, Toffoli, TR, URG and BJN gates. Optimization of the comparator circuit...

in this paper, we introduce a class of rings which is a generalization of reversible rings. let r be a ring with identity. a ring r is called central reversible if for any a,b ∈ r, ab=0 implies ba belongs to the center of r. since every reversible ring is central reversible, we study sufficient conditions for central reversible rings to be reversible. we prove that some results of reversible ri...
