Figure 4.

Single treatment. The effect of single treatment (shaded region at the bottom) on the x-y competing pair of Figure 2(a) with different initial dose D_Y = D₀ = 1.5 vs. 1.85, over an 80-day time span. The upper plots show (as above) the rescaled x,y densities (x-solid, y-dashed), the lower plots the corresponding immune effectors (J,K – solid/dashed, I – thin line).
