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

open access: yesAxioms, 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 ...

Globalization, Stability and the Financial Markets

open access: yesSSRN Electronic Journal, 2009
The turbulence in East Asia, the contagious effects on financial markets of other emerging economies and even on the major world stock markets, and the renewed instability in exchange rates are, I think, warnings of trouble in a world in which capital is free to flow as never before around the world in amounts and at a speed without precedent.

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

open access: yesJournal 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.

Delayed population models with Allee effects and exploitation

open access: yesMathematical Biosciences and Engineering, 2014
Allee effects make populations more vulnerable to extinction, especially under severe harvesting or predation. Using a delay-differential equation modeling the evolution of a single-species population subject to constant effort harvesting, we show that

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

open access: yesMathematics, 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.

Global Stabilization Via Local Stabilizing Actions [PDF]

open access: yesIEEE Transactions on Automatic Control, 2006
Stabilization of a linear, time-invariant system via stabilization of its main diagonal subsystems is the underlying problem in all diagonal dominance techniques for decentralized control. In these techniques as well as all Nyquist-based techniques, sufficient conditions are obtained under the assumption that the collection of the unstable poles of all

Impact of delay on HIV-1 dynamics of fighting a virus withanother virus

open access: yesMathematical Biosciences and Engineering, 2014
In this paper, we propose a mathematical model for HIV-1 infectionwith intracellular delay. The model examines a viral-therapy for controllinginfections through recombining HIV-1 virus with a genetically modifiedvirus.

Global Properties of HIV-1 Dynamics Models with CTL Immune Impairment and Latent Cell-to-Cell Spread

open access: yesMathematics, 2023
This paper presents and analyzes two mathematical models for the human immunodeficiency virus type-1 (HIV-1) infection with Cytotoxic T Lymphocyte cell (CTL) immune impairment.

Global Stability in Large Economies

open access: yesEconomic Theory Bulletin, 2023
Abstract A result is obtained showing how global stability of equilibrium, under the standard tâtonnement dynamic, arises in large economies having a continuous, diffuse distribution of consumers, as well as many goods.

Smoothness dependent stability in corrosion detection

open access: yes, 2014
We consider the stability issue for the determination of a linear corrosion in a conductor by a single electrostatic measurement. We established a global log-log type stability when the corroded boundary is simply Lipschitz. We also improve such a result
