global Dynamics of a Delayed HIV-1 Infection Model with Cell-to-cell Transmission, Humoral Immunity and Immune Impairment

引用

Acta Mathematicae Applicatae Sinica 2024年

作者： Rui xu An-li xue Chen-wei SONg Complex Systems Research Center Shanxi University School of Mathematical Sciences Shanxi University

In this paper, an HIV-1 infection model with intracellular delay, humoral immunity and immune impairment is investigated, in which both virus-to-cell infection and cell-to-cell transmission are *** basic reproduction ratio is calculated and the existence of feasible equilibria is established. By analyzing the distributions of roots of the corresponding characteristic equations, the local asymptotic stability of each of feasible equilibria is established. With the help of appropriate Lyapunov functionals and LaSalle’s invariance principle, it is proved that if the basic reproduction ratio is less than unity, the infection-free equilibrium is globally asymptotically stable, and the virus is eventually eliminated; if the basic reproduction ratio is greater than unity, the chronic-infection equilibrium is globally asymptotically stable. Finally, numerical simulations are carried out to illustrate the effects of some parameters on HIV-1 infection dynamics.

Properties of Ti-Based Hydrogen Storage Alloy

引用

Journal of Power and Energy Engineering 2024年第3期12卷 99-114页

作者： Rui xu Tao Cheng Chaoyu Li xue yang Junfeng Rong Sinopec Research Institute of Petroleum Processing Co. Ltd. Beijing China

An efficient and safe hydrogen storage method is one of the important links for the large-scale development of hydrogen in the future. Because of its low price and simple design, Ti-based hydrogen storage alloys are considered to be suitable for practical applications. In this paper, we review the latest research on Ti-based hydrogen storage alloys. Firstly, the machine learning and density functional theory are introduced to provide theoretical guidance for the optimization of Ti-based hydrogen storage alloys. Then, in order to improve the hydrogen storage performance, we briefly introduce the research of AB type and AB2 type Ti-based alloys, focusing on doping elements and adaptive after treatment. Finally, suggestions for the future research and development of Ti-based hydrogen storage alloys are proposed. .
