In the application and promotion of UAV in the future, remote sensing image information is
transmitted frequently, and its security issues will not be ignored. Aiming at the privacy …

Mathematical epidemiology has a long history of origin and development. In particular,
mathematical modeling and analysis of infectious diseases has become a fundamental and …

This paper proposes a dynamic RNA-encoded color image encryption scheme based on a
chain feedback structure. Firstly, the color pure image is decomposed into red, green, and …

Most of the existing spatial domain image encryption techniques suffer from the difficulty of
resisting cryptographic attacks. For this reason, this paper proposes a frequency-domain …

In this study, we present an immuno-epidemic model to understand mitigation options during
an epidemic break. The model incorporates comorbidity and multiple-vaccine doses through …

This article proposes a secure communication enhancement scheme based on face
detection and chaotic partition permutation. The scheme uses edge detection technology to …

Interaction between prey and predator in the presence of an infectious pathogen is the main
focus of this article. A non-local transmission, that encompasses the possibility of acquiring …

In this paper, we investigate the spatiotemporal dynamics driven by the memory delay and
nonlocal interaction for the memory-based diffusion equation, where the nonlocal interaction …

We consider a SIR-like reaction-diffusion epidemic model which embeds opinion-driven
human behavioural changes. We assume that the contagion rate is theoretically saturated …

Improving epidemic models to better reflect reality has long been a prominent concern for
governments and researchers. This paper presents a novel Susceptible–Infected …
