Simplified calculation of diffusivity for a lattice-based random walk with a single obstacle
Motion of cells in living tissues is hindered by obstacles, which may be stationary or may also move. We present a simplified method to calculate the exact Fickian diffusivity for a tracer particle in a random walk with one obstacle. Keywords: Random walk, Obstacles, Diffusivity, Mean squared displa...
