Constraining 2D Hydrogeological Inversion With 3D Lithological Data

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract In hydrogeology, piezometric data are the key constraints for model calibration. Their limits for three‐dimensional (3D) parameterization have often been pointed out, with water heads commonly regarded as having too little sensitivity to vertical heterogeneity.

Quantifying Water Content of a Landfill With ERT Data by Bayesian Evidential Learning

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Accurate estimation of water storage in municipal solid waste landfills is critical for assessing leachate‐generation risk yet remains challenging due to pronounced heterogeneity. Here we apply Bayesian Evidential Learning (BEL) to directly relate Electrical Resistivity Tomography (ERT) data to total water storage (TWS), bypassing explicit ...

Addressing Various Strategies for Combating the Leaf-Roll Virus in Potato Plants

International Journal of Mathematics and Mathematical Sciences
In this research, we introduced a mathematical simulation that describes the transmission dynamics of the potato leaf-roll virus (PLRV) and involves some control measures to eliminate the propagation of the PLRV disease.

Dynamical Analysis of an HIV Infection Model Including Quiescent Cells and Immune Response

Mathematical Methods in the Applied Sciences, Volume 48, Issue 15, Page 14301-14315, October 2025.
ABSTRACT This research gives a thorough examination of a human immunodeficiency virus (HIV) infection model that includes quiescent cells and immune response dynamics in the host. The model, represented by a system of ordinary differential equations, captures the complex interaction between the host's immune response and viral infection.

A Mathematical Model for the Within-Host Dynamics of Malaria Parasite with Adaptive Immune Responses

International Journal of Mathematics and Mathematical Sciences
Mathematical analysis of epidemics is crucial for long-term disease prediction and helps to guide decision-makers in terms of public health policy. In this study, we develop a within-host mathematical model of the malaria parasite dynamics with the ...

A diffusion-based HIV model with inflammatory cytokines and adaptive immune impairment

Frontiers in Applied Mathematics and Statistics
HIV continues to pose a critical threat to global public health, contributing to a high number of deaths worldwide. The virus predominantly attacks CD4+T lymphocytes, which are essential for coordinating immune responses.

Stability and bifurcation analysis of a nested multi-scale model for COVID-19 viral infection

Computational and Mathematical Biophysics
In this study, a nested multi-scale mathematical model is proposed and studied for COVID-19 viral infection. The well-posedness of the multi-scale model is discussed, followed by the stability analysis of the equilibrium points. The proposed model admits

Co-dynamics of hepatitis B and C viruses under the influence of CTL immunity

Alexandria Engineering Journal
Understanding the cytotoxic T lymphocyte (CTL) immune response against hepatitis B virus (HBV) and hepatitis C virus (HCV) infections is crucial, as these infections can lead to liver cirrhosis and cancer. Mathematical models provide valuable support for

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 ...
