From pandemic to a new normal: Strategies to optimise governmental interventions in Indonesia based on an SVEIQHR-type mathematical model

Infectious Disease Modelling, 2022
There are five different forms of intervention presently realised by the Indonesian government in an effort to end the COVID-19 pandemic: vaccinations, social restrictions, tracings, testings, and treatments.

Modeling the Transmission and Control Dynamics of HIV/AIDS–Cryptococcal Meningitis Co‐Infection

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This study presents a mathematical model for the transmission and control dynamics of HIV/AIDS and cryptococcal meningitis (CM) co‐infection. Using a compartmental framework, a system of differential equations is formulated to represent the susceptible, exposed, pre‐AIDS, AIDS, and co‐infected populations.

Semianalytical Solutions of a Caputo–Fabrizio Fractional Epidemic Model via the q‐Kushare Homotopy Transform Method

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this study, an enhanced semianalytical framework is developed for solving nonlinear fractional differential equations involving the Caputo–Fabrizio fractional operator. The proposed Caputo–Fabrizio q‐Kushare homotopy analysis transform method (CFq‐KHATM) combines the Caputo–Fabrizio derivative, Kushare transform, and q‐homotopy analysis within a ...

Understanding biofilm--phage interactions in cystic fibrosis patients using mathematical frameworks

Computational and Mathematical Biophysics
When planktonic bacteria adhere together to a surface, they begin to form biofilms, communities of bacteria. Biofilm formation in a host can be extremely problematic if left untreated, especially since antibiotics can be ineffective in treating the ...

An Efficient Numerical Study of Measles Transmission Dynamics With Time Delay

Journal of Mathematics, Volume 2026, Issue 1, 2026.
Measles is a highly contagious viral disease that remains a public‐health concern in populations with suboptimal vaccination coverage. In this study, a delayed SEIR‐type epidemic model is formulated to investigate measles transmission dynamics, where the latent period is incorporated through a discrete time delay.

On Linear Growth in COVID-19 Cases

Computational and Mathematical Biophysics, 2020
We present an elementary model of COVID-19 propagation that makes explicit the connection between testing strategies and rates of transmission and the linear growth in new cases observed in many parts of the world.

Fractional Adomian J‐Transform Method for Time‐Fractional Diffusion‐Wave Equations: Theory and Applications

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this research, we introduce the fractional Adomian J‐transform method FAJM, which functions as a robust hybrid analytical‐numerical framework. Diverging from traditional transform techniques, the FAJM leverages the specific scaling attributes of the J‐transform to streamline the inversion of nonlocal fractional operators.
