Shear-induced particle migration and margination in a cellular suspension
We simulate the cross-flow migration of rigid particles such as platelets in a red blood cell (RBC) suspension using the Stokes flow boundary integral equation method. Two types of flow environments
The dynamics of a vesicle in simple shear flow
We have performed direct numerical simulation (DNS) of a lipid vesicle under Stokes flow conditions in simple shear flow. The lipid membrane is modelled as a two-dimensional incompressible fluid with
Lattice-dynamical calculation of phonon scattering at ideal Si–Ge interfaces
Detailed phonon scattering at an ideal Si–Ge interface is studied with a linear lattice dynamics model. Frequency dependent transmission coefficients indicate the significance of acoustic-optical
We study numerically the thermal conductivity in several different one-dimensional chains. We show that the phonon-lattice interaction is the main ingredient of the Fourier heat law. Our argument
Shear-induced platelet margination in a microchannel.
The lateral migration of platelets in a microchannel is studied numerically where the hydrodynamic interactions between red cells, platelets, and vessel walls are resolved by the Stokes flow boundary integral equations and the lateral migration is shown to be diffusional.
The dynamics of a vesicle in a wall-bound shear flow
The simulation of the dynamics of a lipid vesicle in a wall-bound shear flow is simulated by a Stokes-flow boundary integral equation method and shows that the presence of the wall delays the transition from the tank-treading motion to trembling and tumbling.
Coarse-grained theory to predict the concentration distribution of red blood cells in wall-bounded Couette flow at zero Reynolds number
We develop a coarse-grained theory to predict the concentration distribution of a suspension of vesicles or red blood cells in a wall-bound Couette flow. This model balances the wall-induced

In this Letter, I propose that a properly rescaled spatiotemporal correlation function of the energy density fluctuations may be applied to characterize the equilibrium diffusion processes in lattice
