Summary: This work proposes a Lorenz-Sine coupling chaotic system and a novel image encryption scheme. The smooth chaotic attractors with a unique appearance are obtained by adding a nonlinear controller containing a sinusoidal function to the Lorenz system. Based on the proposed chaotic system, a pseudorandom sequence generator is designed to generate keys with high randomness. Furthermore, an image encryption scheme using spiral-rotation and random permutation is presented, which is more capable against differential attacks and more robust against noise attacks and cropping attacks.

Summary: The article investigates single and array of mechanical arms driven by Josephson junction (JJ) circuits and their applications in mimicking the locomotion of myriapods. The stability analysis of a single mechanical arm driven by a JJ circuit reveals two equilibrium points and a switch of their stability for specific values of the stimulation current. Numerical simulations confirm the proposed electromechanical system's ability to mimic the motion of myriapods and overcome the difficulties of coupling many JJ circuits or other neuron circuit models. The progressive excitation of the array of mechanical arms in the electromechanical system, as demonstrated by numerical simulations, resembles the straightforward motion of myriapods.

Summary: The network connectivities are crucial for exhibiting diverse collective dynamics in complex systems. Hindmarsh-Rose neurons connected by electromagnetic interactions are used to demonstrate different dynamical states and transitions. Specifically, the dynamical behaviors of the system are explored under regular, small-world, and random network connectivities. The results show that increasing coupling intensity leads to a transition from desynchronization to traveling wave state for all considered network interactions. Furthermore, the investigation is extended to a three-layer multiplex network where synchronization is achieved in all layers with increasing coupling intensity, eventually reaching a rest state at high coupling strength.
