Generalized Newton's Method based on Graphical Derivatives [PDF]

, 2010
This paper concerns developing a numerical method of the Newton type to solve systems of nonlinear equations described by nonsmooth continuous functions. We propose and justify a new generalized Newton algorithm based on graphical derivatives, which have

Stability of generalized models for HIV-1 dynamics with impaired CTL immunity and three pathways of infection

Frontiers in Applied Mathematics and Statistics
Highly active antiretroviral therapy (HAART) stands out as the most effective treatment for human immunodeficiency virus type-1 (HIV-1). While total eradication is still difficult, HAART can dramatically lower the virus's plasma viral level below the ...

Stability analysis of a diffusive HTLV-2 and HIV-1 co-infection model

Alexandria Engineering Journal
Co-infections between human immunodeficiency virus type 1 (HIV-1) and human T-lymphotropic virus type 2 (HTLV-2) are more common, particularly among injection drug users and individuals engaging in sexual activity.

Optimal control efforts to reduce the transmission of HPV in a fractional-order mathematical model

Boundary Value Problems
Human papillomavirus (HPV) is a sexually transmitted virus that causes cervical cancer in women and leads to death. In this research paper, we prepare a fractional mathematical model that contains a system of four fractional differential equations (FDEs)

Global Dynamics of a Dual-Target HIV Model with Time Delays and Treatment Implications

Mathematics
We present a comprehensive mathematical analysis of a within-host dual-target HIV dynamics model, which explicitly incorporates the virus’s interactions with its two primary cellular targets: CD4+ T cells and macrophages.
