Dependence of collective cell movement on the chirality in the absence of tension fluctuation. (A) Dependence of average quantities on the angle θ₀ in Equation (6): v (red), n_T1 (green), s (blue), and c (purple). To calculate the K_p-dependence of the angular velocity, the time window from t = 60 to 100 was used for this average. Vertical bars indicate standard deviation in the time course. (B–D) Dependency of spatiotemporal correlation functions of fluctuations in locally averaged cell angular velocity $C_{vv}(\Delta \theta ,\Delta t)=\langle \delta v(\theta ,t)\delta v(\theta +\Delta \theta ,t+\Delta t)\rangle /{\sigma }_v^2$ for K_p = 7.5 in the absence of oscillation of chiral line tension; (B) for ${\theta }_0={22.5}^{°}$, (C) for ${\theta }_0={45}^{°}$, and (D) for ${\theta }_0={67.5}^{°}$.
