Figure 3. Effect of model parameters on distribution of hemorrhage volumes.

Panel A depicts combinations of expansion coefficient α and coagulation time constant τ (β = 500). Z-scale is # macrobleed/# microbleeds (log 10 ratio). Panel B shows sample histograms for bimodal conditions with three different levels of decay constants (top: τ = 13; middle: τ = 11, bottom: τ = 9, all with α = 0.01). Red marks in panel B indicate median size of macrobleeds at those parameters (log value 4.71 for τ = 9, 5.62 for τ = 11, and 6.02 for τ = 13, corresponding to the values for macrobleed volume shown in Table 1).
