Near-periodic oscillations. A: A near-periodic time series simulated from a set of ODEs describing Ca2+ oscillations in animal cells [38]. In the y-axes, n stands for the number of interspike intervals (ISI) in the ISI plot, P for probability in the BSA plot and S for spectral power in the FFT plot. The ISI plot show several intervals present (D), but both FFT (B) and BSA (C) identify a frequency around ω = 1.2 rad/s.
