Mingge Deng et al.
Fabrication of functionalized surfaces using polymer brushes is a relatively simple process and parallels the presence of glycocalyx filaments coating the luminal surface of our vasculature. In this paper, we perform atomistic-like simulati...
Modelling single- and tandem-bubble dynamics between two parallel plates for biomedical applications [0.03%]

Carefully timed tandem microbubbles have been shown to produce directional and targeted membrane poration of individual cells in microfluidic systems, which could be of use in ultrasound-mediated drug and gene delivery. This study aims at c...
Motion of red blood cells near microvessel walls: effects of a porous wall layer [0.03%]
红血球在微血管附近的运动：多孔壁层的影响

Daniel S Hariprasad
A two-dimensional model is used to simulate the motion and deformation of a single mammalian red blood cell (RBC) flowing close to the wall of a microvessel, taking into account the effects of a porous endothelial surface layer (ESL) lining...
Electromigration dispersion in a capillary in the presence of electro-osmotic flow [0.03%]

The differential migration of ions in an applied electric field is the basis for separation of chemical species by capillary electrophoresis. Axial diffusion of the concentration peak limits the separation efficiency. Electromigration dispe...

Disease states characterized by airway fluid occlusion and pulmonary surfactant insufficiency, such as respiratory distress syndrome, have a high mortality rate. Understanding the mechanics of airway reopening, particularly involving surfac...
The influence of surfactant on the propagation of a semi-infinite bubble through a liquid-filled compliant channel [0.03%]

We investigate the influence of a soluble surfactant on the steady-state motion of a finger of air through a compliant channel. This study provides a basic model from which to understand the fluid-structure interactions and physicochemical ...

The effects of vascular rarefaction (the loss of small arteries) on the circulation of blood are studied using a multiscale mathematical model that can predict blood flow and pressure in the systemic and pulmonary arteries. We augmented a m...
PRODUCTION OF SOUND BY UNSTEADY THROTTLING OF FLOW INTO A RESONANT CAVITY, WITH APPLICATION TO VOICED SPEECH [0.03%]
声流经波动节流进入共振腔体时的发声现象及其在 voiced speech 中的应用
M S Howe,R S McGowan
M S Howe
An analysis is made of the sound generated by the time-dependent throttling of a nominally steady stream of air through a small orifice into a flow-through resonant cavity. This is exemplified by the production of voiced speech, where air f...
Effect of a soluble surfactant on a finite sized bubble motion in a blood vessel [0.03%]
表面活性剂对血管中有限大小气泡运动的影响研究

T N Swaminathan et al.
We present detailed results for the motion of a finite sized gas bubble in a blood vessel. The bubble (dispersed phase) size is taken to be such as to nearly occlude the vessel. The bulk medium is treated as a shear thinning Casson fluid an...

A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh col...
