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.

Long-Time Performance of Unsplit PMLs with Explicit Second Order Schemes
Journal of Scientific Computing, 41(1), 1–12.
author keywords: Perfectly matched layer (PML); Long-time growth; Wave propagation; Maxwell's equations; Numerical solution; Second order approximation; Yee scheme; Leap-frog scheme; Lax-Wendroff scheme; Central difference/Runge-Kutta scheme; Yee/Runge-Kutta scheme
TL;DR:
Analysis of the temporal behavior of unsplit PMLs for some commonly used second order explicit finite-difference schemes that approximate the Maxwell’s equations finds that the type of the layer and the choice of the scheme play a major role in how rapidly this growth may manifest itself and whether or not it manifests itself at all.
