Fig 5. Shape and velocity of traveling waves in one dimension.

A) Actin and active nucleator concentrations c (green) and n_a (orange) for v_a = 0.8 and ω_d = 0.35. Dots are from a numerical solution, solid lines are obtained from the variational ansatz Eq (23) and the solution Eq (39). B, C) Wave speed as a function of the actin polymerization velocity v_a (B) and the nucleator inactivation parameter ω_d (C). All other parameters as in Table 1.
