Fig. 1.

The growth stretch rate λ̇_g as defined in (1). Illustrative plots are shown for different values of a_g and b_g. (a) Shows the effect of varying the parameter a_g while b_g = 30 Days. (b) Shows the effect of varying the parameter b_g while a_g = 0.01 Day⁻¹. The parameter a_g represents the growth rate at t = 0, while b_g determines the shape of the growth rate function in (1).
