Application of Variable Step‐Size Hybrid Methods for Solving Third‐Order Lane‐Emden Equations

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This manuscript introduces a pair of variable step‐size hybrid methods (PVSHM) to efficiently solve third‐order initial value problems of Lane‐Emden‐type equations (LETE). These equations are extensively used across various disciplines, including chemical engineering, fluid mechanics, physics, and astrophysics, to model a wide range of real ...

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

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
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.

Scenario‐free robust optimization algorithm for IMRT and IMPT treatment planning

open access: yesMedical Physics, EarlyView.
Abstract Background Robust treatment planning algorithms for intensity modulated proton therapy (IMPT) and intensity modulated radiation therapy (IMRT) allow for uncertainty reduction in the delivered dose distributions through explicit inclusion of error scenarios.

Latent space reconstruction for missing data problems in CT

open access: yesMedical Physics, EarlyView.
Abstract Background The reconstruction of a computed tomography (CT) image can be compromised by artifacts, which, in many cases, reduce the diagnostic value of the image. These artifacts often result from missing or corrupt regions in the projection data, for example, by truncation, metal, or limited angle acquisitions.
