OBJECTIVE Standard extracorporeal circulation (ECC) remains the staple procedure for cardiac surgeons. Despite modern membrane oxygenators and arterial filters micro bubbles are regularly detected in the arterial line. We investigated whether initial deairing of the venous drainage during connection can reduce the quantity and size of micro bubbles on the(More)
BACKGROUND The classic increase in P wave size, known as 'P-atriale', is a widely accepted criterion for determination of proper positioning of central venous catheter tips. Recent transoesophageal echocardiography (TOE) studies did not confirm intra-atrial position despite advancing the central venous catheter further than indicated by ECG guidance. We(More)
A random geometric graph Gn is obtained as follows. We takeX1, X2, . . . , Xn ∈ R at random (i.i.d. according to some probability distribution ν on R). For i 6= j we joinXi andXj by an edge if ‖Xi−Xj ‖< r(n). We study the properties of the chromatic number χn and clique number ωn of this graph as n becomes large, where we assume that r(n) → 0. We allow any(More)
At the core of the Robertson-Seymour theory of graph minors lies a powerful structure theorem which captures, for any fixed graph H, the common structural features of all the graphs not containing H as a minor. Robertson and Seymour prove several versions of this theorem, each stressing some particular aspects needed at a corresponding stage of the proof of(More)

Ein Badegewässer soll durchsichtig, geruchlos und sauber, das heißt nicht sichtbar verschmutzt sein und biologisch der oligosaproben oder beta-mesosaproben Stufe des Saprobiensystems nach Kolkwitz & Marsson entsprechen. Anhand einer hygienischen Beurteilung der örtlichen Verhältnisse und mit Hilfe des Colinachweises muß abgeklärt werden, ob nicht eine(More)
A measurement of the top quark mass is reported in events containing a single top quark produced via the electroweak t channel. The analysis is performed using data from proton-proton collisions collected with the CMS detector at the LHC at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 fb−1. Top quark candidates are(More)
Normalized double-differential cross sections for top quark pair (tt) production are measured in pp collisions at a centre-of-mass energy of 8 TeV with the CMS experiment at the LHC. The analyzed data correspond to an integrated luminosity of 19.7 fb−1. The measurement is performed in the dilepton e±μ∓ final state. The tt cross section is determined as a(More)
The recent paper ‘Linear Connectivity Forces Large Complete Bipartite Minors’ by Böhme et al. relies on a structure theorem for graphs with no H-minor. The sketch provided of how to deduce this theorem from the work of Robertson and Seymour appears to be incomplete. To fill this gap, we modify the main proof of that paper to work with a mere restatement of(More)
