Figure 2.
Steady-state solution and settling time. (A) and (B) show the steady-state solutions for the concentration of fAβ and sAβ, respectively. The critical Aβ production rate Rc is shown in the diagram. (C) shows the corresponding settling time, as defined in the inset. It increases abruptly as the production rate gets closer to the critical rate Rc. The inset diagram shows the normalized concentrations in time for the case R = 1.5 × 10−3μM ⋅ day−1 = 1.15 Rc. The estimated physiological production rate is shown by a red-highlighted vertical band in each diagram. To see this figure in color, go online.
