Patch formation driven by stochastic effects of interaction between viruses and defective interfering particles

An illustration of the domain division and interface of the j-th reaction.
Here we show an example with two reactants. The domain is modeled by PDE and the domain
is modeled by compartment-based SSA. The amount of each species in a compartment in
is
. If any reactant amount is below the threshold Θ, then that compartment is part of
. Individuals can move between the boundary compartment of
and the pseudo-compartment in
. In the two-dimensional case, diffusion takes four directions: up, down, left and right.
