Fig. 5.

(A) Average cell response speed vs. shock severity: |μ_f − μ_i|. (B) Δ vs. shock severity |μ_f − μ_i|. (C) Δ vs. σ₂ for the initial ensemble before the step change. (D) σ₂ vs. variance of the cell cycle duration 〈δτ²〉 derived from the autocorrelation function before the step change. (E) Δ vs. variance (bars denote standard deviation). As the variance of the initial CCDD before the environment change increases, Δ decreases, and thus the response efficiency improves. Theory results are displayed as red lines or stars.
