Extraction of the bare form factors for the semi-leptonic decays
No full textThe computation of the form factors for the Bs→Kℓν decay is presented. The b quark is treated by means of Heavy Quark Effective Theory, currently in the static approximation. In these proceedings we discuss the extraction of the bare matrix elements from lattice data through a combined fit to two- and three-point correlation functions, as well as by considering suitable ratios. The different methods agree concerning the extracted form factors and approximately 2% accuracy is reached. The non-perturbative renormalization and matching to QCD is described in accompanying proceedings [PoS(LATTICE2016) 292]
High-Speed Torus Interconnect Using FPGAs
No full textIn this chapter we describe the architecture of a torus interconnect and its implementation on FPGAs, which so far has been used in two different HPC systems. The network design is optimized for applications which benefit from a tightly coupled network and allows to exchange relatively small messages between nearest neighbours at a high rate. Examples for such applications are lattice quantum chromodynamics (LQCD) simulations and fluid dynamics applications using the Lattice Boltzmann method (LBM). We describe the details of the implementation of our torus network architecture for two massively parallel machines, QCD Parallel Computing on Cell (QPACE) and AuroraScience, and present details on the FPGA resource usage. Furthermore, we discuss optimizations which were necessary to fit the design. Finally, we provide an outlook on possible implementation changes when using more recent generations of FPGAs
From Academic to Judge
No full textAbstract
This chapter focuses on the many accomplishments of Judge Bruno Simma. Simma has a global reputation as an academic, the author of fifteen books (several of which had multiple editions) and more than sixty scholarly articles and of many important reports. His celebrity lies not just in his publications, exceptional though they are, it lies in his remarkable drive and vigour and his very special relations with students. His students at Munich and at Michigan have benefited, since 1973 and 1997 respectively, from this dynamism, coupled with a total lack of pomposity. Simma has a voracious appetite for knowledge. He devours, in many languages, books and articles from various sources on a wide variety of subjects. This is for him not a duty, but a pleasure. He is vastly knowledgeable over the generality of international law. He is also one of the great leaders in the field of human rights.</jats:p
Delivery room management of infants with very low birth weight in 3 European countries-the video Apgar study
No full textObjective To assess delivery room management of infants born preterm at 4 Level III perinatal centers in 3 European countries.Study design This was a prospective, multicenter observational study. Management at birth was video-recorded and evaluated (Interact version 9.6.1; Mangold-International, Arnstorf, Germany). Data were analyzed and compared within and between centers.Results The infants (n = 138) differed significantly with respect to the median (25%, 75%) birth weight (grams) (Center A: 1200 [700, 1550]; Center B: 990 [719, 1240]; Center C: 1174 [835, 1435]; Center D: 1323 [971, 1515] [B vs A, C, D: P < .05]), gestational week (Center A: 28.4 [26.3, 30.0]; Center B: 27.9 [26.7, 29.6]; Center C: 29.3 [26.4, 31.0]; Center D: 30.3 [28.0, 31.9]), Apgar scores, rates of cesarean delivery, and time spent in the delivery room. Management differed significantly for frequency and drying time, rates of electrocardiographic monitoring, suctioning or stimulation, and for fundamental interventions such as time for achieving a reliable peripheral oxygen saturation signal (seconds) (Center A: 97.6 +/- 79.3; Center B: 65.1 +/- 116.2; Center C: 97.1 +/- 67.0; Center D: 114.4 +/- 140.5; B vs A, C, D: P < .001) and time for intubation (seconds) (Center A: 48.7 +/- 4.2; Center B: 49.0 +/- 30.7; Center C: 69.1 +/- 37.9; Center D: 65.1 +/- 23.8; B vs D, P < .025). Mean procedural times did not meet guideline recommendations. The sequence of interventions was similar at all centers.Conclusions The Video Apgar Study showed great variability in and between 4 neonatal centers in Europe. The study also showed it is difficult to adhere to published guidelines for recommended times for important, basic measures such as peripheral oxygen saturation measurements and intubation.Developmen
