Detrended fluctuation as a function of the window size or scale (s) for the entire time period (upper left) of the WT (black), Vdiff (blue) and PAdiff (green). The filled circles and continuous lines correspond to the actual data, whereas the empty circles and dashed lines correspond to the same, but randomly re-arranged (shuffled), data. The same analysis but for each phase of the cycle applied to the PAdiff (upper right), Vdiff (lower left) and WT (lower right). The αs value during each phase of the cycle is marked with the corresponding color. Open circles and dashed lines correspond to the DFA applied to a random vector created for comparison purposes.
