Fig. 5From: Critical behavior of spatial networks as a model of paracrine signaling in tumorigenesisProbability Distribution Function (PDF) plotted on a logarithmic scale. The network was generated using Eq. (2) for a network arrested at t=2500, and valency parameter m=2 The power law exponent is measured as γ=2.539, and is linear on a least squares fit with correlation coefficient ρ=0.951Back to article page
