The method to merge matrix elements for multi particle production and parton showers in e+e− annihilations and hadronic collisions and its implementation into the new event generator SHERPA is described in detail. Examples highlighting different aspects of it are thoroughly discussed, some results for various cases are presented. In addition, a way to extend this method to general electroweak i...

INTRODUCTION Currently, the gold standard for donor organ preservation in clinical organ transplantation consists of 3 plastic bags and an ice box. The first plastic bag includes the organ itself immersed in preservation solution (e.g. Celsior). This bag is put in a second bag filled with saline, and then these two are put in a third bag filled with saline which is then put in the ice box.  The...

Abstract. We present the D0 measurement of correlations in the azimuthal angle between the two largest transverse momentum jets produced in pp̄ collisions at a center-of-mass energy √ s = 1.96 TeV in the central rapidity region [1]. The results are based on an inclusive dijet event sample corresponding to an integrated luminosity of 150 pb−1. Data is in good agreement with next-to-leading order ...

PurposeTraditionally, after procurement, donor hearts are cooled with ice during transport to the transplant center. However, this can lead uneven cooling and result in tissue injury, which may affect subsequent allograft function. The utilization of a hypothermic preservation system (SherpaPak, Paragonix) results controlled uniform cooling. This approach enable longer-distance procurements bet...
