Fig. 2. Simulated ERES-like clusters keep their distance. (a) The steady state of the simulation obtained for physiological parameters (see Materials and Methods) yields a pattern of spots that is reminiscent of the ERES pattern in mammalian cells. (b) The statistics of normalized next-neighbor distances between visible clusters, p(s), obtained from the simulations (histogram), show marked deviations from the naïve prediction of clusters distributed randomly and independently (Eqn 1; dashed line). A good description of the data is given by an analytical expression derived within random matrix theory (Eqn 2, unbroken line). The pattern has quasi-crystalline characteristics.
