Chemical computing based on Turing patterns in two coupled cells with equal transport coefficients

摘要: We study instabilities leading to inhomogeneous stationary states (discrete Turing patterns) using a simple model of glycolytic oscillatory reaction in two mass-coupled stirred open reactors with equal coupling coefficients the activator and inhibitor explore their ability serve as logical devices. The system represents simplest coupled cell system. It is found possess coexisting stable homogeneous oscillations pair complementary asymmetric patterns. examine transitions from regime patterns, or one pattern another, elicited by targeted perturbations specific for each type transition. further develop our earlier proposition patterns chemical computing functions available Digital memory storage, sensor, signal conducting module logic gates NAND, AND, OR, NOR, NOT are found. main advantage two-cell that it can basic unit construction lattice representing universal processor, whereas larger linear circular arrays more suitable tailor-made operations.
