Decompression sickness is known to be due to the formation of bubbles in the body as a result of decompression. It is likely that these bubbles form from pre-existing nuclei, which, for bubbles in the bloodstream, are thought to be housed within blood vessel walls. Gas pockets emerging from these sites will be subject to forces due to blood flow, a portion of the gas eventually being swept away to form a free bubble in the bloodstream. These continue to grow and may grow to similar dimensions to the vessel, developing into elongated "gas plugs," potentially occluding the flow. In this correspondence, we derive a simple model to investigate whether this vessel occlusion is a serious concern.

    We obtain Light curves of 22 variables, 10 of which are newly detected objects. We Identify four detached eclipsing binaries and eight contact binaries. Accurate Periods are found for all but two variables. Nineteen variables are Proper-motion members of the cluster, and the remaining three are fiel...

    We theoretically consider the carrier density tuned (apparent) Two-dimensional (2D) metal-insulator-transition (MIT) in semiconductor Heterostructure-based 2D carrier systems as arising from a classical Percolation phenomenon in the inhomogeneous density landscape created by the Long-range potential...

    We study a diffusion limit of Vlasov-Poisson-Fokker-Planck (VPFP) systems on a bounded domain with reflection Boundary conditions of charge distributions. Here the VPFP system has a small Parameter coming from the hypotheses of the scaled thermal velocity and mean Free path of charged particles. Und...
