Molecular diffusion at the surface of living cells is believed to be predominantly driven by thermal kicks. However, there is growing evidence that certain cell surface molecules are driven by the fluctuating dynamics of cortical cytoskeleton. Using fluorescence correlation spectroscopy, we measure the diffusion coefficient of a variety of cell surface molecules over a temperature range of 24-3...

Diffusion-driven water uptake in a substrate (imbibition) is a subject of great interest in the field of food technology. This is a particular challenge for rice grains that are preprocessed to accelerate the water uptake, i.e., to reduce the cooking time. Rice preprocessing disrupts the mesostructural order of starch and induces a microporous structure in the grains. The mesoand microstructura...

A magnon and a phonon are the quanta of spin wave lattice wave, respectively, they can hybridize into polaron when their frequencies wavenumbers match close enough values at exceptional point. Guided by an analytically calculated dispersion, dynamical phase-field simulations performed to investigate effects formation on attenuation bulk acoustic in magnetic insulator film. It is shown that stro...

In this paper, we present a unified approach for hidden markov model based multilingual speech recognition. The proposed approach could be used across acoustically similar as well as diverse languages. We use an automatic phone mapping algorithm to map phones across languages and reduce the effective number of phones in the multililingual acoustic model. We experimentally verify the effectivene...

In this paper, a finite element based simulation approach for predicting the effect of microstructure on the stresses resulting from electromigration-induced diffusion is described. The electromigration and stress-driven diffusion equation is solved coupled to the mechanical equilibrium and elastic constitutive equation, where a diffusional inelastic strain is introduced. Here, the focus is on ...

An effective white-noise Langevin equation is derived that describes long-time phase dynamics of a limit-cycle oscillator driven by weak stationary colored noise. Effective drift and diffusion coefficients are given in terms of the phase sensitivity of the oscillator and the correlation function of the noise, and are explicitly calculated for oscillators with sinusoidal phase sensitivity functi...

We compare application of two partial differential equation methods in image enhancement. The first method is based on the curvature-driven min/max flow and originates from the level set methods. The second method is an anisotropy diffusion flow. The curvature-driven method seems to enhance better the significant edges in the image, whereas the anisotropic diffusion seems to work better with sm...
