Modelling structural determinants of ventilation heterogeneity: A perturbative approach.

Autor: Carl A Whitfield, Alex Horsley, Oliver E Jensen

Publikováno v: PLoS ONE, Vol 13, Iss 11, p e0208049 (2018)

We have developed a computational model of gas mixing and ventilation in the human lung represented as a bifurcating network. We have simulated multiple-breath washout (MBW), a clinical test for measuring ventilation heterogeneity (VH) in patients wi

During pregnancy, oxygen diffuses from maternal to fetal blood through villous trees in the placenta. In this paper, we simulate blood flow and oxygen transfer in feto-placental capillaries by converting three-dimensional representations of villous a

Although superhydrophobic surfaces (SHSs) show promise for drag reduction applications, their performance can be compromised by traces of surfactant, which generate Marangoni stresses that increase drag. This question is addressed for soluble surfact

The dynamics of blood flow in the smallest vessels and passages of the human body, where the cellular character of blood becomes prominent, plays a dominant role in the transport and exchange of solutes. Recent studies have revealed that the micro-ha

Couple stresses and discrete potentials in the vertex model of cellular monolayers

Autor: Oliver E, Jensen, Christopher K, Revell

Publikováno v: Biomechanics and modeling in mechanobiology.

The vertex model is widely used to simulate the mechanical properties of confluent epithelia and other multicellular tissues. This inherently discrete framework allows a Cauchy stress to be attributed to each cell, and its symmetric component has bee
