Fig. 8:

PDE model simulations with a spatially-uniform time-varying monomer source S₁₀ = m₀λ exp(−λt) for (a) m₀ = 2, (b) m₀ = 4, and (c) m₀ = 8. Each curve corresponds to a specific λ value as indicated in the legend, and the points along each curve are for the different k_b values with the large dot indicating k_b = 1/8 and the k_b values increasing from that point to k_b = 32 at the other end of the curve.
