Figure 3. Volume-exclusion effects between F-actins lead to collective motions of F-actins.
Actin concentration (CA) is varied with reference strength of repulsive forces (κr,A / κ*r,A = 1). (a) Time evolution of network morphology with CA = 60 μM. Thin bundles emerge first, and then thick bundles and ring-like structures are formed later. (b) Final network morphology with different CA. (c) A correlation between network morphology at the end of simulations (100 s) and that at each time point. For example, a correlation value at 50 s represents a correlation between network morphology at 50 s and that at 100 s. Higher correlation values at later times in cases with large CA indicate that network morphology does not change significantly near the end. (d) A correlation between velocities of pairs of endpoints on F-actins located at a distance r, which is averaged for last 50 s.
