We study the embedding of spacetime filling D7–branes in β–deformed backgrounds which, according to the AdS/CFT dictionary, corresponds to flavoring β–deformed N = 4 super Yang–Mills. We consider supersymmetric and more general non–supersymmetric three parameter deformations. The equations of motion for quadratic fluctuations of a probe D7–brane wrapped on a deformed three–sphere exhibit a non–...

In this paper we study the simulation of marginally stable systems using the methods of Quantized State Systems of first order (QSS) and second order (QSS2). We show that the simulation global error can be bounded by a magnitude which grows linearly with the time. Consequently, the direct use of QSS and QSS2 in these systems yields unstable simulation results. Therefore, we propose a modificati...

We derive local integral and supestimates for the curvature of stably marginally outer trapped surfaces in a sliced space-time. The estimates bound the shear of a marginally outer trapped surface in terms of the intrinsic and extrinsic curvature of a slice containing the surface. These estimates are well adapted to situations of physical interest, such as dynamical horizons.

We have performed direct numerical simulation of fully developed turbulent flow in a straight duct with square cross-section. The main objective of the present study is to determine the minimal requirements for maintaining turbulence in duct flows [1]. A detailed analysis of this limit regime allows to elucidate the dominant mechanisms governing the marginally turbulent state, where the self-su...

Some effects are statistically significant. Other effects do not reach the threshold of statistical significance and are sometimes described as “marginally significant” or as “approaching significance.” Although the concept of marginal significance is widely deployed in academic psychology, there has been very little systematic examination of psychologists’ attitudes toward these effects. Here,...

A second virial theory of the isotropic-to-nematic phase transition in solutions of slightly flexible micelles is presented. It is shown that even a infinitesimal flexibility of the micelles can suppress the divergences one would obtain when modeling the micelles as infinitely

Land degradation is recognized as one of the major threats to the buffer zones of protected areas (PAs) in Vietnam. In particular, the expansion of land degradation into the PAs is exerting pressure on biodiversity conservation efforts. This degradation is partially the result of mismanagement: the utilization of the land is often unmatched with the inherent suitability of the land. Identificat...
