FIGURE 8.

Thermal versus active unbinding of motors at the filament end in centered systems. Profiles of the bound motor density ρ_b as a function of the radial coordinate r for motors moving (a) inwards and (b) outwards in asterlike filament arrays. At the end of the filaments, motors detach with the same probability as at any other filament site (solid lines) or by a forward step, i.e., with rate α (dashed lines). The inset in b shows the region close to the filament ends where the profiles for the two cases differ. The parameters are as in Fig. 7.
