Kin recognition in plants-an ecological perspective: an overview of plant kin recognition under different resources, consequences and future challenges

Journal of Plant Interactions
Kin recognition in plants is a debated topic, with mixed evidence on whether plants can distinguish kin from non-kin and adjust their behavior accordingly.

Stability and bifurcation analysis of an HIV-1 infection model with a general incidence and CTL immune response

Journal of Biological Dynamics, 2021
In this paper, with eclipse stage in consideration, we propose an HIV-1 infection model with a general incidence rate and CTL immune response. We first study the existence and local stability of equilibria, which is characterized by the basic infection ...

Stability of HIV-1 Dynamics Models with Viral and Cellular Infections in the Presence of Macrophages

Axioms, 2023
In this research work, we suggest two mathematical models that take into account (i) two categories of target cells, CD4+T cells and macrophages, and (ii) two modes of infection transmissions, the direct virus-to-cell (VTC) method and cell-to-cell (CTC ...

Global stability of the positive equilibrium for a non-cooperative model of nuclear reactors

Electronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper, we investigate the non-cooperative reaction-diffusion model of nuclear reactors subject to the homogeneous Neumann boundary condition. By establishing appropriate Lyapunov functions, we prove the global stability of the unique positive ...

Global stability of nonlinear feedback systemswith positive descriptor linear parts [PDF]

Bulletin of the Polish Academy of Sciences: Technical Sciences, 2019
The global (absolute) stability of nonlinear systems with negative feedbacks and positive descriptor linear parts is addressed. Transfer matrices of positive descriptor linear systems are analyzed.

Modeling Typhoid Fever Dynamics: Stability Analysis and Periodic Solutions in Epidemic Model with Partial Susceptibility

Mathematics, 2023
Mathematical models play a crucial role in predicting disease dynamics and estimating key quantities. Non-autonomous models offer the advantage of capturing temporal variations and changes in the system.

CHOICES FOR GLOBAL SOCIAL STABILITY [PDF]

IFAC Proceedings Volumes, 2008
Abstract Scientists and societal leaders increasingly agree that human activity is irretrievably changing the environment in which human life and other life forms co-exist. Action to reduce human impact on the environment is an imperative prerequisite to achieving social stability.

Rational Use of Herbal Products in Pediatric Patients Treated With Anticancer Drugs in the European Union

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The use of herbal medical preparation (HMP) is rising among pediatric oncology patients, often to manage treatment‐related symptoms. Their effectiveness remains uncertain, and the risk of herb–drug interactions is underestimated.

Global Behavior of a Multi–Group Seir Epidemic Model with Spatial Diffusion in a Heterogeneous Environment

International Journal of Applied Mathematics and Computer Science, 2022
In this paper, we propose a multi-group SEIR epidemic model with spatial diffusion, where the model parameters are spatially heterogeneous. The positivity and ultimate boundedness of the solution, as well as the existence of a global attractor of the ...
