Fig. 4From: Critical behavior of spatial networks as a model of paracrine signaling in tumorigenesisGeometry of the dynamic model in a 2-D metric space. The two distinct populations of nodes are distributed homogeneously about the two loci A and B in a circle of radius D. These are separated by a distance δs, and for a given node in set A its distance s is a function of its coordinate (ri,θi) relative to the locus of ABack to article page
