Summary: In this paper, a new 5D memristive exponential hyperchaotic system is proposed and its fundamental dynamics characteristics are analyzed. The system exhibits a rich set of dynamic behaviors when appropriate parameter sets are chosen. The system is implemented using the Field Programmable Gate Array (FPGA) and the experimental results are consistent with the numerical simulation results on MATLAB. An image encryption application based on the system is presented, and the security analysis demonstrates the feasibility and effectiveness of the image encryption algorithm.

Summary: This paper investigates the robust exponential synchronization of inertial memristive neural networks (IMNNs) with time-varying delays and parameter disturbance through event-triggered control (ETC) scheme. The delayed IMNNs are transformed into first-order MNNs with parameter disturbance by constructing proper variable substitutions. Then, a state feedback controller is designed for response IMNNs with parameter disturbance, and ETC methods are provided to decrease the update times of controller.

Summary: This paper introduces a nonvolatile locally active memristor with three stable equilibrium states for three-bit-per-cell memory device functionality. A neural network model composed of three Hopfield neurons is presented, showing that the distribution of system equilibrium points depends on the coupling weight of the memristor synapse. The bifurcation diagram reveals the coexistence phenomenon of multiple stable modes, with complex bursting oscillation emerging in the neural network when there is a step difference between the system's natural frequency and the external excitation frequency.

Summary: By introducing trigonometric functions, a new 2D hyperchaotic map with conditional symmetric attractors is constructed, revealing both symmetric and asymmetric hyperchaotic attractors, as well as attractor growth under specific circumstances. The polarity balance of the discrete map is restored by applying sinusoidal functions and inverting the constant term. These properties are unique to this chaotic map and hardware implementation based on STM32 confirms the theoretical analysis and numerical simulation.
