摘要：

A unified approach to synchronization of noisy and chaotic systems is described. The approach can be used to address the inverse problem of identification of the presence of weak interaction between natural systems from bivariate data. The analysis allows researchers to learn from observations in various fields how weakly coupled complex systems interact. A previously unknown nonlinear feature of cardiorespiratory interaction, the well-expressed cardiorespiratory synchronization in humans, is discussed. Subjects with epochs of synchronization between the cardiac and respiratory rhythms have no remarkable respiratory-modulated heart rate fluctuations, whereas subjects with higher RSA exhibit no distinct epochs of cardiorespiratory synchronization.
