Supersymmetry theory of diffusion is elaborated to study analytically a non-equilibrium binary mixture with relaxation of diffusion flux. Within such a scheme, Bose components represent order parameter and amplitude of fluctuations of the diffusion flux, while the mutually conjugated combination of Fermi-components gives the mixture concentration. For above variables, the system of equations is...

The present study evaluates MBCM and GMM solutions for both ASV and ASI problems involving text-independent telephone speech from the King speech database. The MBCM's accuracy is enhanced by selectively removing those classi ers within the model which perform worst (pruning). An unpruned MBCM outperforms a GMM for ASV and speakers taken from within the same dialectic region (San Diego, CA). Onc...

The effect of an aminosilane on the lubricant properties of a C(18) double-chained cationic surfactant has been investigated in the context of glass fiber forming process. The surfactant adsorption was studied on silica by Fourier transform infrared (FT-IR) spectroscopy in the attenuated total reflexion (ATR) mode as a function of the aminosilane concentration in an organic water based formulat...

The dragging velocity of a model solid lubricant confined between sliding periodic substrates exhibits a phase transition between two regimes, respectively, with quantized and with continuous lubricant center-of-mass velocity. The transition, occurring for increasing external driving force F ext acting on the lubricant, displays a large hysteresis, and has the features of depinning transitions ...

The implementation of solid colloidal particles suspended in a binary fluid mixture via the lattice Boltzmann method is described. To represent colloids in a binary mixture, boundary conditions for mass and momentum at the solid-fluid interface are extended to include a conserved compositional order parameter. The parallelisation of the fluid-particle problem is addressed, and its scaling inves...

In this work, we incorporated a quartic bond potential into a coarse-grained bead-spring model to study lubricant adsorption on a solid surface as well as depletion instability. The surface tension density and the number density profiles were examined to verify the solid-liquid and liquid-vapor interfaces during heat treatment. It was found that both the liquid-vapor interfacial thickness and t...

We present a new approach for signal separation from an undetermined instantaneous mixture of two BPSK (Binary Phase Shift Keying) signals in AWGN (Additive White Gaussian Noise) channel. The method uses frequency diversity of the mixture (frequency shift between carriers) and the fact that signals of interest are binary variables. We compare separation results of our method to a theoretical BE...

Within the idealized scheme of a 1-dimensional Frenkel-Kontorova-like model, a special ”quantized” sliding state was found for a solid lubricant confined between two periodic layers [1]. This state, characterized by a nontrivial geometrically fixed ratio of the mean lubricant drift velocity 〈vcm〉 and the externally imposed translational velocity vext, was understood as due to the kinks (or soli...

The phase diagram of a polydisperse mixture of uniaxial rodlike and platelike hard parallelepipeds is determined for aspect ratios kappa=5 and 15. All particles have equal volume, and polydispersity is introduced in a highly symmetric way. The corresponding binary mixture is known to have a biaxial phase for kappa=15, but to be unstable against demixing into two uniaxial nematics for kappa=5. T...

BACKGROUND This paper explores the exposure and impact of a Scottish mass media campaign: Make Your Position Clear. It ran from October 2009 to July 2010, targeted gay men and other men who have sex with men (MSM), and had two key aims: to promote regular sexual health and HIV testing every 6 months, and to promote the use of appropriate condoms and water-based lubricant with each episode of an...
