From: Landscape reveals critical network structures for sharpening gene expression boundaries
Two dimensional simulations for the boundary sharpening effects over time at different gene expression noise level d for the self-activation model. Blue: X is expressed, red: Y is expressed. a for d = 0, b for d = 0.01, c for d = 0.02. d-f Landscape at different morphogen level (M = 0.4 for d, M = 0.6 for e, and M = 1.2 for f) for the self-activation model. g Switching time and barrier heights change with morphogen level M. h Barrier heights versus the switching time. i Average switching time versus noise level at different k. Parameter k represents the strength of self-activation. j Diagram for the self-activation model
