Cell adhesion plays a central role in multicellular organisms helping to maintain their integrity and homeostasis.This complex process involves many different types of adhesion proteins, and synergeti...
Phenomenological model for ordered onions under shear flow
Phenomenological model ordered onions under shear flow
2010/11/23
We here propose a phenomenological model for the multi-lamellar vesicles (onions) formation
induced by shear flow. In a nonionic surfactant (C12E4) system, onion phases under a fixed shear flow show ...
Stochastic Structural Stability Theory applied to roll/streak formation in boundary layer shear flow
Stochastic Structural Stability Theory boundary layer shear flow
2010/11/16
Stochastic Structural Stability Theory (SSST) provides an autonomous, deterministic, nonlinear dynamical system for evolving the statistical mean state of a turbulent system. In this work SSST is appl...
Nonlinear saturation of Rayleigh-Taylor instability and generation of shear flow in equatorial spread-F plasma
Nonlinear saturation Rayleigh-Taylor instability shear flow equatorial spread-F plasma
2009/11/12
An analysis of low order mode coupling equations is used to describe the nonlinear behaviour of the Rayleigh-Taylor (RT) instability in the equatorial ionosphere. The nonlinear evolution of RT instabi...
Higher-order Korteweg-de Vries models for internal solitary waves in a stratified shear flow with a free surface
Higher-order Korteweg-de Vries models internal solitary waves stratified shear flow
2009/11/12
A higher-order extension of the familiar Korteweg-de Vries equation is derived for internal solitary waves in a density- and current-stratified shear flow with a free surface. All coefficients of this...

Stochastic resonance nonlinear model shear flow stochastic inertia-gravity wave parameterization
2009/11/11
We report on a numerical study of the impact of short, fast inertia-gravity waves on the large-scale, slowly-evolving flow with which they co-exist. A nonlinear quasi-geostrophic numerical model of a ...

The classical one-dimensional advection-diffusion equation (ADE) gives an inadequate description of tracer cloud evolution in the River Severn, U.K. A solute transport model incorporating the effects ...
Equatorial Kelvin and Inertio-Gravity Waves in Zonal Shear Flow
Equatorial Kelvin Inertio-Gravity Waves Zonal Shear Flow
2009/2/13
The interaction of geostrophic zonal mean currents in an equatorial ocean with free, neutrally stable, internal Kelvin and inertio-gravity waves is investigated using a two-layer, reduced-gravity mode...

Mean Shear Flow Equatorial Basin Modes
2009/2/8
We test the sensitivity of energy trapping by equatorial basin modes to the presence of mean currents in a series of numerical experiments. At low frequency, trapping persists in the form of modified ...
