Synchronization levels with different forcing periods.

is the fraction of time points (between 300 min and 700 min) at which more than 95% or less than 5% of the cells are budded during 700 min simulations. The simulation statistics (mean standard deviation) of are computed from 15 independent realizations per forcing period. In each realization, a budding index trajectory is generated from a single pedigree of cells. Each pedigree starts from a single cell and the number of cells within the pedigree increases exponentially due to cell division. Values that are in parentheses are from the pedigrees that are initiated by single mother cells, whereas the remaining values are from the pedigrees that start with daughter cells. Results are consistent with these different initial condition choices.
