A G-quadruplex-hemin complex assembled at an electrode surface may exhibit "smart" behaviors under benign conditions, which can be further used in fabricating a set of logic gates. Desirably, these logic gates can be integrated into a logic network with the advantages of integrity, unification and reversibility.

in this paper a novel all-optical logic nand, nor and xor gate based on nonlinear directional coupler theory is demonstrated. we use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. in other words, while a beam with 4 w/μm in power considered as logical one, the output is nand gate and if a beam w...

Logical gates studied in quantum computation suggest a natural logical abstraction that gives rise to a new form of unsharp quantum logic. We study the logical connectives corresponding to the following gates: the Toffoli gate, the NOT and the √ NOT (which admit of natural physical models). This leads to a semantic characterization of a logic that we call computational quantum logic (CQL).

Logic gates made of DNA have received significant attention as biocompatible building blocks for molecular circuits. The majority of DNA logic gates, however, are controlled by the minimum number of inputs: one, two or three. Here we report a strategy to design a multi-input logic gate by splitting a DNA construct.

We designed and constructed versatile modular genetic logic gates in bacterial cells. These function as digital logic 1-input Buffer gate, 2-input and 3-input AND gates with one inverted input and integrate multiple chemical input signals in customised logic manners. Such rapidly engineered devices serve to achieve increased sensing signal selectivity.

Abstruct Behavior of basic and complex logic gates using complementary pass-transistor logic (CPL) under various single-stuck faults are investigated. The result shows that all stuck-on faults in the basic CPL gates can be detected by current monitoring, but no logic monitoring is possible. Similarly all bridging faults between gate and source of basic CPL gates can be detected only by current ...

Phased Logic (PL) is a synthesis and mapping methodology that translates a standard synchronous gate-level netlist to a non-clocked netlist of special gates called phased logic gates [1][2][3]. In this paper the implementation of PL gates and the switched capacitance of phased logic systems is discussed. An analysis of the dynamic power consumption of a phased logic system reveals a major defic...

Multiple and configurable fluorescence logic gates were fabricated via self-assembly of layered double hydroxides and various chromophores. These logic gates were operated by observation of different emissions with the same excitation wavelength, which achieve YES, NOT, AND, INH and INHIBIT logic operations, respectively.
