2009 journal article
Analysis of Viscoelastic Wall Properties in Ovine Arteries
IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING, 56(2), 210–219.
author keywords: Arterial wall properties; data analysis; mathematical modeling; mechanics; parameter estimation; viscoelasticity
MeSH headings : Algorithms; Animals; Arteries / physiology; Biomechanical Phenomena / physiology; Blood Pressure; Elasticity; Equipment Design; Male; Models, Cardiovascular; Nonlinear Dynamics; Sensitivity and Specificity; Sheep; Signal Processing, Computer-Assisted; Viscosity
TL;DR:
Results reveal that elastic properties in both models vary across locations (smaller arteries are stiffer than larger arteries), and show that for all locations, the inclusion of viscoelastic behavior is important to capture pressure-area dynamics.

A smoothing technique for discrete delta functions with application to immersed boundary method in moving boundary simulations
JOURNAL OF COMPUTATIONAL PHYSICS, 228(20), 7821–7836.
author keywords: Immersed boundary method; Moving boundary; Non-physical force oscillations; Smoothed discrete delta function
TL;DR:
It has been shown that the smoothed discrete delta functions constructed in this paper have one-order higher derivative than the regular ones, which can effectively suppress the non-physical oscillations in the volume forces and improve the accuracy of the immersed boundary method with direct forcing in moving boundary simulations.
