The volume change and the strain energy stored in an isotropic elastic matrix by a disperse substitution of spherical inclusions are determined by a non-linear analysis which accounts for the second-order elastic e€ects. When reduced to linear theory, the results are compared with those of Eshelby. Ó 1999 Published by Elsevier Science Ltd. All rights reserved.

A method is described for embedding a deformable, elastic, membrane within a lattice Boltzmann fluid. The membrane is represented by a set of massless points which advect with the fluid and which impose forces on the fluid which are derived from a free energy functional with a value which is dependent upon the geometric properties of the membrane. The method is validated in two dimensions with ...

Flexoelectric liquid crystalline membranes immersed in asymmetric viscoelastic media is a material system model with physiological applications such as outer hair cells (OHCs), where membrane oscillations generate bulk flow. Motivated by this process, here we extend our previous work characterizing the force transmission output of addition to fluid flow, since solid–fluid interactions are an es...

The current study focuses on the modeling and analysis of acoustic scattering from an elastic membrane disc located in a cylindrical waveguide that may involve structural discontinuities. physical problem is governed by Helmholtz’s equation involves higher order boundary conditions at interfaces. Mode-Matching (MM) method conjunction with Galerkin formulation developed to solve governing value ...

OBJECTIVES This study sought to assess the rate and predictors of 1-year restenosis after drug-eluting stent implantation for femoropopliteal (FP) lesions in patients with peripheral arterial disease. BACKGROUND Zilver PTX, a paclitaxel-eluting stent for FP lesions, provides superior outcomes to angioplasty and bare-metal stents in clinical trials. However, its real-world outcomes and the ass...

Although the auger-like 'swimming' motility of the African trypanosome was described upon its discovery over one hundred years ago, the precise biomechan-ical and biophysical properties of trypanosome flagellar motion has not been elucidated. In this study, we describe five different modes of flagellar beat/wave patterns in African trypanosomes by microscopically examining the flagellar movemen...
