A Selective Image Encryption Scheme Based on 2D DWT, Henon Map and 4D Qi Hyper-Chaos

open access: yesIEEE Access, 2019
In recent years hyperchaos has found applications in several fields such as medicine and engineering. It has been applied in image-based applications which require reliable, fast, and robust security systems to store or/and transfer images.

Classical-quantum localization in one dimensional systems: The kicked rotor

open access: yesAIP Advances, 2022
This work explores the origin of dynamical localization in one-dimensional systems using the kicked rotor as an example. In particular, we propose the fractal dimension of the phase space as a robust indicator to characterize the onset of classical chaos.

Chaos dynamics of charged particles near Gibbons-Maeda-Garfinkle-Horowitz-Strominger black holes

open access: yesNuclear Physics B
The Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) dilatonic black hole, a key solution in low-energy string theory, exhibits previously unexplored chaotic dynamics for charged test particles under electromagnetic influence.

Robust chaos in $\mathbb{R}^n$

open access: yes
We treat $n$-dimensional piecewise-linear continuous maps with two pieces, each of which has exactly one unstable direction, and identify an explicit set of sufficient conditions for the existence of a chaotic attractor. The conditions correspond to an open set within the space of all such maps, allow all $n \ge 2$, and allow all possible values for ...

Chaos-Modulated Spiking Neural Networks for Seizure Detection: A Dynamical Systems Approach to Clinical EEG

open access: yesIEEE Access
Automated seizure detection from EEG remains challenging due to signal complexity and the need for patient-independent generalization. While deep learning offers high accuracy, it lacks interpretability regarding neural dynamics. Spiking Neural Networks (

Robust synchronization of a class of coupled delayed networks with multiple stochastic disturbances: The continuous-time case [PDF]

open access: yes, 2011
In this paper, the robust synchronization problem is investigated for a new class of continuous-time complex networks that involve parameter uncertainties, time-varying delays, constant and delayed couplings, as well as multiple stochastic disturbances.
