Figure 6.

Typical patterns emerging from random initial conditions in stochastic simulations for different values of parameters κ and ${\gamma }_1$. Other parameters are as follows: ${\gamma }_2=1,n_0=10,\delta =0.01,{\delta }_A=0.02,{\gamma }_A=0.004,P_n=0.1,D_A=12.5$. The system size is 256 × 256. Because the number of cells must be integers in stochastic simulations, we use unscaled parameters here. To see this figure in color, go online.
