A Spring–Dashpot System for Modelling Lung Tumour Motion in Radiotherapy

open access: yesComputational and Mathematical Methods in Medicine, Volume 11, Issue 1, Page 13-26, 2010., 2010
A 3D system of springs and dashpots is presented to model the motion of a lung tumour during respiration. The main guiding factor in configuring the system is the spatial relationship between abdominal and lung tumour motion. A coupled, non‐dimensional triple of ordinary differential equations models the tumour motion when driven by a 3D breathing ...

Stenosis effects on Jeffrey fluid flow in two-layer microcirculatory models: a physicochemical and hemorheological analysis

open access: yesComputational and Mathematical Biophysics
Blood is a multifaceted colloidal suspension of plasma as an aqueous electrolyte-protein fluid and cellular components, mainly red blood cells, the rheology of which is influenced by mutually reinforcing hydrodynamic and chemical interactions, such as ...

Hemodynamic properties of blood flow in an angled overlying stenosed blood vessel via force field and gold nanoparticle suspension

open access: yesScientific African
A review of the literature on nanoparticles indicates that the use of nanofluids in hematological treatments is growing. This effort presents a theoretical investigation of the non-linear behavior of blood flow mixed with suspensions of gold ...

A novel approach for feline sporotrichosis pathogen detection based on loop‐mediated isothermal amplification

open access: yesVeterinary Dermatology, Volume 36, Issue 4, Page 474-484, August 2025.
Background – Sporotrichosis is a chronic, mycotic infection caused by fungi of the genus Sporothrix. Zoonotic sporotrichosis occurs mainly through S. brasiliensis transmission, resulting from the organism's traumatic introduction via scratches or bites, or contact with exudate from contaminated cats.

A muscle crossbridge theory with internal crossbridge dynamics

open access: yesComputational and Mathematical Biophysics
We develop a crossbridge model in which an attached crossbridge behaves like a linear spring with a variable rest length. We assume in particular that the rest length has a linear force–velocity relation, and that the force and rest length are both zero ...

Augmenting heart disease prediction with explainable AI: A study of classification models

open access: yesComputational and Mathematical Biophysics
Although heart disease stands as a prominent contributor to worldwide deaths, not all individuals affected by it ultimately fall prey to its effects. Timely diagnosis and effective treatment can offer those with heart conditions a high-quality life in ...

On building machine learning models for medical dataset with correlated features

open access: yesComputational and Mathematical Biophysics
This work builds machine learning models for the dataset generated using a numerical model developed on an idealized human artery. The model has been constructed accounting for varying blood characteristics as it flows through arteries with variable ...
