A Fluid–Structure Interaction Analysis to Investigate the Influence of Magnetic Fields on Plaque Growth in Stenotic Bifurcated Arteries

Dynamics
A finite element method is employed to examine the impact of a magnetic field on the development of plaque in an artery with stenotic bifurcation. Consistent with existing literature, blood flow is characterized as a Newtonian fluid that is stable ...

Bayesian Modelling of Skull Conductivity Uncertainties in EEG Source Imaging

, 2017
Knowing the correct skull conductivity is crucial for the accuracy of EEG source imaging, but unfortunately, its true value, which is inter- and intra-individually varying, is difficult to determine.

Review on solving the forward problem in EEG source analysis [PDF]

, 2007
Background: The aim of electroencephalogram ( EEG) source localization is to find the brain areas responsible for EEG waves of interest. It consists of solving forward and inverse problems.

Exposure to extremely low frequency (50 Hz) electromagnetic field changes the survival rate and morphometric characteristics of neurosecretory neurons of the earthworm Eisenia foetida (Oligochaeta) under illumination stress [PDF]

, 2013
An in vivo model was set up to establish the behavioral stress response (rate of survival) and morphometric characteristics of A1 protocerebral neurosecretory neurons (cell size) of Eisenia foetida (Oligochaeta) as a result of the synergetic effect of

Magnetic noise around metallic microstructures

, 2007
We compute the local spectrum of the magnetic field near a metallic microstructure at finite temperature. Our main focus is on deviations from a plane-layered geometry for which we review the main properties.

MHD analysis of couple stress nanofluid through a tapered non-uniform channel with porous media and slip-convective boundary effects

International Journal of Thermofluids
The current research addresses the peristaltic transport mechanism that propels fluid through a conduit through rhythmic contraction and relaxation of the conduit walls, a phenomenon evident in numerous biological systems, including the gastrointestinal ...

Investigation of Heart Valve Dynamics: A Fluid-Structure Interaction Approach

Fluids
This study presents a numerical investigation into the heart valve through a fluid–structure interaction (FSI) framework using a two-dimensional, steady-state, Newtonian flow assumption. While simplified, this approach captures core biomechanical effects
