Simulations of two and three cells rotating on circular substrates. (a) Autocorrelation function of cell velocity. (b) Robustness of cell rotation is influenced by the polarization fluctuation σ. (c and d) Phase diagrams of cell rotation for two and three cell systems, respectively. (e) The rotation frequency ω versus the persistent memory decay rate, β. There is an insensitive region (pink) in which the rotation does not depend on the variance of σ. (f) Dependence of ω on the strength of persistent force α. For large β the relationship is linear, and the slope is explained by Eq. 9. To see this figure in color, go online.
