Multiscality in the dynamics of coupled chaotic systems

We investigate the scaling features of complex motions in systems of two coupled chaotic oscillators by means of the wavelet-transform modulus maxima method and the detrended fluctuation analysis. We show that the transition from asynchronous to synchronous dynamics typically reduces the degree of multiscality in the characteristic temporal scales. Correlation properties caused by adjustment of the involved time scales are discussed, and experimental results for coupled functional units of the kidney are analyzed.
