The asymptotic formulas for the 4-simplex amplitude of the EPRL and FK Euclidean spin foam models and the Lorentzian EPRL model are given. We give a geometrical phase choice for the boundary state. Copyright © 2012 by World Scientific Publishing Co. Pte. Ltd. Source

Since October 2012 we use the Edwards ThruPort IntraClude Intra-Aortic Occlusion Device instead of direct aortic clamping for minimally invasive mitral valve reconstruction. The device allows a gentle occlusion of the aorta with no further manipulation. Beside a low pressure on the aortic wall it has the advantage that no additional needle vent is required for cardioplegia. This allows time saving as well as the avoidance of bleeding complications. It further minimizes the preparation of the operative situs and thus also reduces markedly the pericardial incision. Source
