Nowadays, reversible logic is one of the most important issue which has emerged as a promising technology having its applications in low power CMOS, quantum computing, nanotechnology and optical computing. Reversible logic circuits give less power dissipation as well as distinct output that is assigned for each distinct input. The classical set of gates such as the NAND, AND, NOR, OR, XOR and X...

The newly appeared idea of Logical Stochastic Resonance (LSR) is verified in synthetic gene networks induced by non-Gaussian noise. We realize the switching between two kinds of logic gates under optimal moderate noise intensity by varying two different tunable parameters in a single gene network. Furthermore, in order to obtain more logic operations, thus providing additional information proce...

An abelian processor is an automaton whose output is independent of the order of its inputs. Bond and Levine have proved that a network of abelian processors performs the same computation regardless of processing order (subject only to a halting condition). We prove that any finite abelian processor can be emulated by a network of certain very simple abelian processors, which we call gates. The...

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...

Biochemical logic circuits that precisely control gene activity in cells are useful for creating novel living organisms with well-defined purposes and behaviors. An important element in designing and implementing these circuits is matching logic gates such that the couplings produce the correct behavior. In this paper, we report in-vivo experimental results that examine and optimize the steady ...

Simple cellular logic circuits have been built by engineering the DNA of host cells. Similar to systems found in nature, these circuits use repressor protein concentrations as logic signals; a gate’s input repressors interact with the cell’s DNA to influence the production of the gate’s output repressors. A limitation in building these circuits is the number of unique repressor proteins availab...

This paper investigates a novel design of penternary logic gates usingcarbon nanotube field effect transistors (CNTFETs). CNTFET is a suitable candidate forreplacing MOSFET with some useful properties, such as the capability of having thedesired threshold voltage by regulating the diameter of the nanotubes. Multiple-valuedlogic (MVL) such as ternary, quaternary, and penternary is a promising al...

We report herein a set of deoxyribozyme-based logic gates capable of generating any Boolean function. We construct basic NOT and AND gates, followed by the more complex XOR gate. These gates were constructed through a modular design that combines molecular beacon stem-loops with hammerhead-type deoxyribozymes. Importantly, as the gates have oligonucleotides as both inputs and output, they open ...

A conceptually new logic gate based on DNA has been devised. Methoxybenzodeazaadenine ((MD)A), an artificial nucleobase which we recently developed for efficient hole transport through DNA, formed stable base pairs with T and C. However, a reasonable hole-transport efficiency was observed in the reaction for the duplex containing an (MD)A/T base pair, whereas the hole transport was strongly sup...
