Here, we consider either a square lattice representing a sheet (d = 2) embedded in three-dimensional space, or a cubic lattice (d = 3).
MCRS is implemented as a stochastic cellular automaton (SCA) model on a square lattice representing the mineral surface to which the replicators are anchored.
The methane self-diffusion coefficient in the presence of coadsorbed benzene and ethylene was reduced in a manner qualitatively consistent with concepts from percolation theory applied to a diamond lattice (representing the connectivity of the NaY supercages).
For simplicity, we assume that individuals are located at nodes of a square lattice representing their geographical distribution.
In addition, we introduce another set of static, predefined regions, also based on a hexagonal lattice, representing regions of high coreactivity as described above (assumption 10— Fig. 3 e,f ).
The simulations were performed using a two-dimensional lattice representing a section of the thymic lobule (cortex and medulla) derived from actual C57BL/6 mouse thymus histological cross section as seen in Figure 8.
A valve in one lattice, representing a given gene cluster, may have a different default (wild type) setting than the same valve in a different lattice (representing a different gene cluster).
If the outer loop were unrolled, then Algorithm 1 partitioning the array space would yield the 128 lattices partitioning M, as displayed in Fig. 8, instead of the linearly bounded lattice representing the partition M from Fig. 6.
Actually, there is no need to perform any modification of the behavioral specification: the smaller lattices can be obtained by "slicing" the lattice representing M for the different values of the first iterator.
Each of the 300×300 grid-points of the square lattice represent a site for a single bacterium; all the sites are always occupied, i.e., bacteria may replace each other, but may not leave empty sites.
