indivisible or a mitogen-activated protein kinase (MAPK) cascade pathway. We have
a cellular communication process from X to Y as illustrated in Figure 18.3a and
signal molecules travel from X toward Y . A simple way to simulate this stochastic
diffusion process is to use the Monte Carlo method. If the neighborhood of the
signal molecules is defined by a two-dimensional lattice (e.g., Moore neighborhood
in cellular automata), the correlation of the concentration values whose measures are
spatially distributed provides an indication on the spreading process of molecular
signaling, which exhibits a kind of receive-and-forward ...
