We present results from a comprehensive number of relativistic, time-dependent, axisymmetric simulations of the runaway instability of non-constant angular momentum thick discs around black holes. This second paper in the series extends earlier results where only constant angular momentum discs were considered. All relevant aspects of the theory of stationary thick discs around rotating black h...

We have observed 22 young stars from the Lindroos sample (Lindroos 1986) at 850 μm with SCUBA on the JCMT to search for evidence of dust discs. Stars in this sample are the less massive companions of B-type primaries and have well defined ages that are 10 − 170 Myr; i.e., they are about to, or have recently arrived on the main sequence. Dust was detected around three of these stars (HD74067, HD...

A new clustering algorithm called k-discs is introduced. This algorithm, though similar to k-means, addresses the de ciencies of k-means as well as its variant k-subspaces. The k-discs algorithm is applied to the recovery of manifolds from noisy samplings. A kernelization of k-discs is exhibited, and the advantages of this modi cation are demonstrated on synthetic data. For this project, the ke...

A hallmark of early IVD degeneration is a decrease in proteoglycan content. Progression will eventually lead to matrix degradation, a decrease in weight bearing capacity and loss of disc height. In the final stages of IVD degradation, fissures appear in the annular ring allowing extrusion of the NP. It is crucial to understand the interplay between mechanobiology, disc composition and metabolis...

Purpose: The aim of this study was to investigate the influence of nicotine and cotinine, two major components of tobacco, on fungal biofilm formation on two acrylic resins. Additionally, the nystatin susceptibility of the planktonic and biofilm fungal cells was compared. Materials and Method: Ivocap and Lucitone 199 polished and roughened acrylic resin discs were fabricated and randomly assign...

This is a study of square-tiled translation surfaces in the stratum H(2) and their SL(2, R)-orbits or Teichmüller discs, which are arithmetic. We prove that for prime n > 3 translation surfaces tiled by n squares fall into two Teichmüller discs, only one of them with elliptic points, and that the genus of these discs has a cubic growth rate in n.

Impaired nutrition of the intervertebral disc has been hypothesized to be one of the causes of disc degeneration. However, no causal relationship between decreased endplate perfusion and limited nutrient transport has been demonstrated to support this pathogenic mechanism. To determine the importance of endplate perfusion on solute diffusion into the nucleus pulposus and to show causality of en...
