Memory-flow structures in Lorenz chaos

Memory-flow structures of a coupled three-element model, here a Lorenz chaos, have been investigated. Although in the models of coupled two-element systems, a bidirectional connectivity of information transference is held and the memory flows of one channel exhibit a nearly out-of-phase relation, it is found that in this Lorenz chaos one additional unidirectional connectivity can also occur and the nearly out-of-phase relation in the coupled two-element models will be replaced by an antiphaselike relation in Lorenz chaos.
