Model for hepatitis C virus transmissions
Mathematical Biosciences and Engineering, 2013 Hepatitis C virus (HCV) is a leading cause of chronic liver disease. Thispaper presents a deterministic model for HCV infection transmission and usesthe model to assess the potential impact of antiviral therapy.

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 ...

Delayed population models with Allee effects and exploitation
Mathematical 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

Global stability in job systems
Journal of Mathematical Analysis and Applications, 1988 A simple job system with n grades is introduced here and it is described by a system \(\dot x_ i=x_ i\sum^{n}_{j=1}a_{ij}x_ j\), \(i=1,2,...,n\). The per capita growth rate coefficients \(a_{ij}\) are such that \(a_{ii}0\), \(i\neq j\). Under these conditions a complete picture of the phase portrait of the system is presented as follows: Let \(A=(a_{ij}

Smoothness dependent stability in corrosion detection
, 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

Lagrange stability of semilinear differential-algebraic equations and application to nonlinear electrical circuits [PDF]
, 2018 We study a semilinear differential-algebraic equation (DAE) with the focus on the Lagrange stability (instability). The conditions for the existence and uniqueness of global solutions (a solution exists on an infinite interval) of the Cauchy problem, as ...

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

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