Truss geometry and topology optimization with global stability constraints
Structural And Multidisciplinary Optimization, 2020 In this paper, we introduce geometry optimization into an existing topology optimization workflow for truss structures with global stability constraints, assuming a linear buckling analysis.

Stability of Global Monopoles Revisited [PDF]
Physical Review Letters, 2000 We analyze the stability of global O(3) monopoles in the infinite cutoff (or scalar mass) limit. We obtain the perturbation equations and prove that the spherically symmetric solution is classically stable (or neutrally stable) to axially symmetric, square integrable, or power-law decay perturbations.

Susceptible-Infected-Treatment model with disease infection in prey population recovered by treatment [PDF]
Computational Ecology and Software, 2022 This paper describes a mathematical model with Susceptible-Infected-Treatment under disease infection in prey population. The controls methods are one is separating control that is to separate the prey from infected prey by means of self quarantine and ...

Global dynamics of IAV/SARS-CoV-2 coinfection model with eclipse phase and antibody immunity
Mathematical Biosciences and Engineering, 2023 Coronavirus disease 2019 (COVID-19) and influenza are two respiratory infectious diseases of high importance widely studied around the world. COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), while influenza is ...

Dynamic analysis of a cytokine-enhanced viral infection model with infection age
Mathematical Biosciences and Engineering, 2023 Recent studies reveal that pyroptosis is associated with the release of inflammatory cytokines which can attract more target cells to be infected. In this paper, a novel age-structured virus infection model incorporating cytokine-enhanced infection is ...

An SEIR model with infectious latent and a periodic vaccination strategy
Mathematical Modelling and Analysis, 2021 An SEIR epidemic model with a nonconstant vaccination strategy is studied. This SEIR model has two disease transmission rates β1 and β2 which imitate the fact that, for some infectious diseases, a latent person can pass the disease into a susceptible one.

Analysis of General Humoral Immunity HIV Dynamics Model with HAART and Distributed Delays
Mathematics, 2019 This paper deals with the study of an HIV dynamics model with two target cells, macrophages and CD4 + T cells and three categories of infected cells, short-lived, long-lived and latent in order to get better insights into HIV infection within the

A novel criterion for global incremental stability of dynamical systems [PDF]
, 2022 In this paper, we establish the sufficient conditions guaranteeing global uniform exponential stability, or at least global asymptotic stability, of all solutions for nonlinear dynamical systems, also known as global incremental stability (GIS) of the systems.

Global stability of an age-structured epidemic model with general Lyapunov functional
Mathematical Biosciences and Engineering, 2019 In this paper, we focus on the study of the dynamics of a certain age structured epidemic model. Our aim is to investigate the proposed model, which is based on the classical SIR epidemic model, with a general class of nonlinear incidence rate with some ...
