This study numerically investigates the vortex-induced vibration (VIV) of an elastically mounted rigid cylinder by using Reynolds-averaged Navier-Stokes (RANS) equations with computational fluid dynamic (CFD) tools. CFD analysis is performed for a fixed-cylinder case with Reynolds number (Re) = 104 and for a cylinder that is free to oscillate in the transverse direction and possesses a low mass...

Dr J C Adams (1871-1951), at the time of the award of his MD degree, 15 July 191 1. It was in 191 1 that Adams submitted his MD thesis to the Queen's University of Belfast. Regrettably, the original has now disappeared, but Baron was able to read it in 1969 and now tells us that Adams had carefully studied 20 patients with proven duodenal ulcer. Fourteen of these, including many with pyloric st...

We give a short and streamlined proof of the following statement recently proven by author M. Zeinalian: cobar construction dg coassociative coalgebra normalized singular chains on path-connected pointed space is naturally quasi-isomorphic as associative algebra to based loop space. This extends classical theorem F. Adams originally for simply connected spaces. Our relating functor left adjoint...

We give the first tight integrality gap for Vertex Cover in the Sherali-Adams SDP system. More precisely, we show that for every > 0, the standard SDP for Vertex Cover that is strengthened with the level-6 Sherali-Adams system has integrality gap 2− . To the best of our knowledge this is the first nontrivial tight integrality gap for the Sherali-Adams SDP hierarchy for a combinatorial problem w...

ADAMs (a disintegrin and metalloprotease) are membrane-bound enzymes, capable of shedding a multitude of proteins from the surface of the cell. They are therefore considered crucial modulators of physiological and pathophysiological processes. The structure and function of ADAMs is related to those of a family of snake venom metalloproteases which also possess a potential adhesion domain as wel...
