A genetic network model's stability and bifurcation was analyzed by using Euler method in this paper. Then the bifurcation theory is used to analyze the existence of bifurcation, the direction of the bifurcation and stability of a genetic network model. Numerical simulations illustrate the paper's analysis and results.
Surface dependence of the nonlinear voltage transfer characteristic in the GaAs-based three-branch nanowire junction (TBJ) is investigated both theoretically and experimentally. A simple model considering the surface-potential-dependent carrier density in the channel reveals a clear relationship between the surface potential and the curvature of the bell-shaped transfer curve. Based on this model,...
