We show how open strings cease to propagate when unstable D-branes decay. The information on the propagation is encoded in BSFT two-point functions for arbitrary profiles of open string excitations. We evaluate them in tachyon condensation backgrounds corresponding to (i) static spatial tachyon kink (= lower dimensional BPS D-brane) and (ii) homogeneous rolling tachyon. For (i) the propagation ...

We have performed an experimental study on the evolution of sand ripples formed under the action of an oscillatory flow. An annular sand-water cell was used in order to investigate a wide range of parameters. The sand ripples follow an irreversible condensation mechanism from small to large wavelength until a final state is reached. The wavelength and the shape of these stable sand patterns are...

This talk concerns a preconditioning method of AMLI type [3] for the solution of linear partial differential equations systems. An earlier idea of this study was proposed in [2] for scalar case. In this work we want to make some further extension of the study done in [1], in particular we propose to give a robust preconditioning iterative schemes using domain decomposition methods. Based on a s...

In this talk we introduce a new certification framework for the port-reduced static condensation reduced basis element (PR-SCRBE) method [1, 3], which has been developed for the simulation of large component based applications such as bridges or acoustic waveguides. In an offline computational stage we construct a library of interoperable parametrized reference components; in the subsequent onl...

We present the first experimental realization of Bose–Einstein condensation in a purely magnetic double-well potential. This has been achieved by combining a static Ioffe–Pritchard trap with a time orbiting potential. The double trap can be rapidly switched to a single-harmonic trap of identical oscillation frequencies, thus accelerating the two condensates towards each other. Furthermore, we s...

We consider the mean field kinetic equations describing the relaxation dynamics of a lattice model of a fluid confined in a porous material. The dynamical theory embodied in these equations can be viewed as a mean field approximation to a Kawasaki dynamics Monte Carlo simulation of the system, as a theory of diffusion, or as a dynamical density functional theory. The solutions of the kinetic eq...

The thermodynamic properties of a shell bosons with the inner surface locating at Planck length away from horizon Schwarzschild black holes by using statistical mechanics are studied. covariant partition function is obtained, which Bose-Einstein condensation found non-zero temperature in curved spacetimes. As special case bosons, we analyze entropy photon gas near hole, shows an area dependence...

Carrier particle spray freeze-drying is a new technology with high added value for thermosensitive powder freeze-drying. The includes the following steps: atomization, coating, freezing, and drying. Due to action of carrier particles, condensation frozen droplets in conventional process overcome. However, there are many influencing factors involved freezing coating. mechanism complex droplet co...

We introduce two generalized condensation principles: Local Club Condensation and Stationary Condensation. We show that while Strong Condensation (a generalized Condensation principle introduced by Hugh Woodin in [19]) is inconsistent with an ω1-Erdős cardinal, Stationary Condensation and Local Club Condensation (which should be thought of as weakenings of Strong Condensation) are both consiste...
