Since the Lorenz chaotic system was discovered in 1963, the construction of chaotic
systems with complex dynamics has been a research hotspot in the field of chaos. Recently …

With the development of economic globalization, demands for digital business data sharing
among different subsidiary companies are constantly emerging. How to achieve secure …

Abstract Rectified Linear Unit (ReLU) is an extremely simple activation function with two-
segment linearity and is usually used in convolutional neural network. To simplify the analog …

This work focuses on the dynamics of a small network of three ring-coupled unidirectional
Rayleigh-Duffing oscillators. The equations governing the Rayleigh-Duffing oscillator …

This work deals with the regular and chaotic dynamics of a system made up of two Hopfield-
type neurons with two different activation functions: the hyperbolic tangent function and the …

This paper investigates the dynamics of a Hopfield inertial bi-neuron with double memristive
synaptic weights. The dynamical behavior of the system is investigated with both numerical …

This work studies the dynamics of a three dimensional Hopfield neural network focusing on
the impact of bias terms. In the presence of bias terms, the models displays an odd symmetry …

Recently, the reveal of novel hidden attractor and multistability in a chaotic system got much
attention due to increasing use of complex chaotic systems in engineering problems. In this …

In this paper, the influence of non-monotonic nonlinearity within the dynamics of the Thomas
model is studied. The system presents various six-scroll chaos over a wide range of …

In this work, we consider the geomagnetic field inversion model proposed by Gissinger et
al.[Europhys. Lett. 90 (4), 49001 (2010)], where a quadratic term is added for symmetry …
