Suppose that cells divide with rate l, die with rate d, become quiescent with rate α, and “wake up” from quiescence with rate β. We will refer to parameters α and β as quiescence parameters. Note that the “amount of quiescence” in the colony correlates positively with α and negatively with β. Let us denote by i the number of cycling cells and by j the number of quiescent cells. The system’s sta...
