Figure 3.
Simulation results for Vtar = 12.5, Γ = 0, and αm = 0.1. (a) Top left panel: myosin profile for χ = 80 and Dϕ = 20. Top right panel: myosin profile for χ = 200 and Dϕ = 20. Bottom right panel: myosin profile for χ = 200 and Dϕ = 5. Scale bar, 1. (b) Different trajectories of the droplet center depending on χ for Dϕ = 20. Trajectories have been aligned artificially to ease visualization. (The direction of motion is chosen randomly, although there is some tendency for cell velocity to lock to the lattice directions or diagonals at long time, which is expected for a finite difference simulation on a square lattice.) (c) The velocity of the droplet is shown as a function of contractility χ for Dϕ = 20. The black solid line with circles corresponds to the droplet center of mass, and the black dashed line with crosses to the myosin center of mass. The red curves with squares correspond to αm = 1.
