This month's cover image is from the featured paper, Numerical solutions of reaction-diffusion equations: Application to neural and cardiac models by Yanyan Claire Ji and Flavio H. Fento. The paper describes the implementation of the explicit Euler, Crank-Nicolson, and implicit alternating direction methods for solving partial differential equations and apply these methods to obtain numerical solutions of three excitable-media models used to study neurons and cardiomyocyte dynamics. The authors discuss the implementation, accuracy, speed, and stability of these numerical methods
