Modeling a tethered polymer in Poiseuille flow

The Journal of Chemical Physics, 2005
We investigate the behavior of a tethered polymer in Poiseuille flow using a multiscale algorithm. The polymer, treated using molecular dynamics, is coupled to a solvent modeled by the stochastic rotation algorithm, a particle-based Navier–Stokes integrator.

Peptide Terminated Polymer Brush Nanomaterials for Label‐Free Separation of Cancer Cells Based on Relative Adhesion

Small, EarlyView.
Horan et al. demonstrate that RGD peptide‐functionalized poly(ethylene glycol) brush films synthesized in polydimethylsiloxane microfluidic channels by surface‐initiated atom transfer radical polymerization enable label‐free separation of melanoma and ovarian cancer cells based on differential integrin expression.

Slip flow in an annular sector duct using radial eigenfunctions

Theoretical and Applied Mechanics Letters, 2014
The fully developed slip flow in an annular sector duct is solved by expansions of eigenfunctions in the radial direction and boundary collocation on the straight sides. The method is efficient and accurate. The flow field for slip flow differs much from

A prospective randomised comparison of two different stenting sutures when using the Baerveldt 101–350 aqueous shunt – Lab transition to clinical process

Acta Ophthalmologica, EarlyView.
Abstract Purpose The Baerveldt glaucoma drainage implant (BGI 101–350) is one of the most effective treatment options for managing refractory glaucoma. To mitigate early hypotony in non‐valved implants, intraluminal occluding sutures (IOSs) are commonly used.

Levitating spherical particle in a slightly tapered tube at low Reynolds numbers: Application to the low-flow rate rotameters [PDF]

, 2012
In this study, a theoretical framework is developed to predict the equilibrium conditions of a non-neutrally buoyant sphere placed in a vertical conical tube as encountered in liquid rotameters.

Comparison of Resistive Index and Volume Flow in Ultrasound of Arteriovenous Fistula for Dialysis Access

Hemodialysis International, EarlyView.
ABSTRACT Introduction Despite extensive investigation, the optimal method of assessing arteriovenous fistula (AV fistula) function remains elusive. Ultrasound is an important tool in the assessment of AV fistula, with a wide range of protocols and flow criteria used across the literature. However, the operator dependency of ultrasound has the potential

Knots in Polymer Molecules Under Poiseuille Flow

Foundations
Knots are ubiquitous in polymers and biological macromolecules such as DNA and proteins, yet their behavior and functionality are still not sufficiently explored.

Kerguelen Plume Drives the Eocene Directional Change in Australian Plate Motion [PDF]

Lithosphere
Australia undergoes a directional plate motion change from westward to northward motion in the early Cenozoic that is associated with Australia/Antarctica separation.
