BACKGROUND This study investigated early and midterm outcomes after valve-sparing aortic root replacement (VSSR procedure with De Paulis Valsalva graft) for acute aortic dissection or ascending aortic aneurysm in a single Chinese hospital center. METHODS Between September 2005 to July 2013, 38 patients (84.2% male; mean age, 45.5 ± 12.4) underwent VSSR procedure with De Paulis valsalva graft ...

Conventional discrete approximations of a manifold do not preserve its nontrivial topological features. In this article we describe an approximation scheme due to Sorkin which reproduces physically important aspects of manifold topology with striking delity. The approximating topological spaces in this scheme are partially ordered sets (posets). Now, in ordinary quantum physics on a manifold M ...

We show that recent data from HERA on the proton structure function F2 at small x and large Q 2 provide a direct confirmation of the double asymptotic scaling prediction of perturbative QCD. A linear rise of lnF2 with the scaling variable σ is observed throughout the kinematic region probed at HERA, and the measured slope is in excellent agreement with the QCD prediction. This provides a direct...
