The period of the limit cycle as a function of vitamin supplementation levels. As the vitamin supplementation level increases beyond 伪 c = 2.63 脳 1013 molecules/渭L per day, changes in the dynamics of the limit cycles can be observed. Insets (a) and (b) show the limit cycle at 伪 = 2.8 脳 1013 and 伪 = 4.45 脳 1013, respectively. In the insets, the uninfected and infected cell concentrations are respectively represented by the solid and dashed lines.
