Dependence of the zero-rate energy function ${\displaystyle \hat{z}\left(t\right)}$ effect on the functional tumor-associated vasculature B and immune recruitment rate r. Dependence of the effect of ${\displaystyle \hat{z}\left(t\right)}$ on the model parameters r and B in the unstable regime of ${\displaystyle L}$ denoted by U. The label (S)stands for the regime where the spiral point is stable and tumor control is reached.
