Maximum rate of change of the fold-mean-concentration as a function of the corresponding rate of LIS collapse for five cases from Fig. 4, B and C. Individual squares represent the maximum rate of concentration change for a given rate of collapse. For example, in the case of t_collapse = 10 s, the LIS collapses by 85% linearly over 10 s, and thus the rate of collapse is constant and equal to 0.085 s⁻¹. For this 10-second collapse, the maximum rate of change of concentration was obtained by finding the largest slope of the C_mean(t)/C_mean(t = 0) curve (see 10-s curve in Fig. 4 C).
