Uniform persistence in a prey–predator model with a diseased predator [PDF]
Journal of Mathematical Biology, 2019 Following the well-extablished mathematical approach to persistence and its recent developments we give a rigorous theoretical explanation to the numerical results obtained for a certain prey-predator model with functional response of Holling type II equipped with an infectious disease in the predator population.

Relaxed Persistent Flow/Jump Conditions for Uniform Global Asymptotic Stability [PDF]
IEEE Transactions on Automatic Control, 2014 For hybrid systems, sufficient conditions are derived for the uniform global asymptotic stability of a given closed set. These conditions are written in terms of a Lyapunov function candidate and assume a semiglobal practical persistent flow (resp. persistent jump) property of the solutions to the hybrid system.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

ANAPT: Additive Noise Analysis for Persistence Thresholding
, 2022 We introduce a novel method for Additive Noise Analysis for Persistence Thresholding (ANAPT) which separates significant features in the sublevel set persistence diagram of a time series based on a statistics analysis of the persistence of a noise ...

Uniform persistence and chain recurrence
Journal of Mathematical Analysis and Applications, 1989 The concept of persistence originates in mathematical ecology and tries to grasp the important property of a community whether it will stay on in the future or not. Definitions can be found in \textit{G. Butler}, \textit{H. Freedman}, \textit{P. Waltman}, Proc. Am. Math. Soc. 96, 425-430 (1986; Zbl 0603.34043)] and in \textit{G.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Perturbation of a Globally Stable Steady State and Uniform Persistence [PDF]
Journal of Dynamics and Differential Equations, 2008 The aim of this paper is to describe the global stability of a parametrized family of uniformly persistent semi-flows, with continuous or discrete time, for which there exist an upper-semicontinuous family of global attractors. Applications to some models of age-structured population dynamics are provided.

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Threshold dynamics of a delayed predator–prey model with impulse via the basic reproduction number
Advances in Difference Equations, 2018 In this paper, we study a delayed predator–prey model with impulse and, in particular, the existence of the predator-free periodic solution. We employ the approach and techniques coming from epidemiology and calculate the basic reproduction number for ...

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in
