This paper investigates the dependence of synchronization transitions of bursting oscillations on the information transmission delay over scale-free neuronal networks with attractive and repulsive coupling. It is shown that for both types of coupling, the delay always plays a subtle role in either promoting or impairing synchronization. In particular, depending on the inherent oscillation perio...

The possibility of a resonant excitation of a free oscillation mode with an observed period of 4.2311 d in the star 51 Pegasi by the tidal action of a low-mass companion is investigated. A free oscillation mode with the observed period is shown to correspond to a g+-mode of a high radial order. For the determination of the tidal displacement in a component of a close binary system of stars near...

A simple memristive chaotic jerk system with one variable to represent the internal state is found. The proposed equilibria-free yields hidden oscillation in a narrow parameter space. circuit constructed that models system, and it shows agreement predicted oscillation. new appears be of algebraically simplest systems.
