We consider the Ricker model with delay and constant or periodic stocking. We found that the high stocking density tends to neutralize the delay effect on stability. Conditions are established on the parameters to ensure the global stability of the e

This extensive survey is an invited contribution to the Encyclopedia of Mathematical Physics, 2nd edition. It covers both classical and more modern aspects of configuration spaces of points on a "ground space" $M$. Most results pertain to $M$ a manif

Deterministic policies are often preferred over stochastic ones when implemented on physical systems. They can prevent erratic and harmful behaviors while being easier to implement and interpret. However, in practice, exploration is largely performed

We consider $k$-dimensional discrete-time systems of the form $x_{n+1}=F(x_n,\ldots,x_{n-k+1})$ in which the map $F$ is continuous and monotonic in each one of its arguments. We define a partial order on $\mathbb{R}^{2k}_+$, compatible with the monot

Lipreading involves using visual data to recognize spoken words by analyzing the movements of the lips and surrounding area. It is a hot research topic with many potential applications, such as human-machine interaction and enhancing audio speech rec

Hydatidosis, caused by the larval stage of Echinococcus granulosus, is a zoonotic disease typically affecting the liver and lungs. Cerebral localizations are rare, especially in the brainstem. We present a case of a 9-year-old boy with a brainstem hy

Abstract Background Activation of innate immunity is a first line of host defense during acute critical illness (ACI) that aims to contain injury and avoid tissue damages. Aberrant activation of innate immunity may also participate in the occurrence

Abstract This review explores the hidden hazards associated with the reuse of treated wastewater and sewage sludge in agriculture while proposing mitigation strategies. It examines the origins and pathways of microplastics (MPs) in wastewater treatme

In this paper we extend results on reconstruction of probabilistic supports of random i.i.d variables to supports of dependent stationary $\mathbb R^d$-valued random variables. All supports are assumed to be compact of positive reach in Euclidean spa
