Background: Resistant Enterobacteriaceae have become a worldwide epidemic during the last decade and are a great threat to health care worldwide. International travel is a major risk factor for becoming colonized with extended-spectrum beta-lactamase (ESBL)-producing bacteria. Data on the persistence of colonization with ESBL-producing bacteria in the faecal flora are limited.Methods: A prospectiv
PURPOSE: A straight thoracic stent graft often complies poorly with the curvature of the aortic arch. We have previously reported an in vitro model of a modified stent graft that can be bent in situ after deployment to improve conformance to the aortic arch. We now report the first clinical experience with this technique in three consecutive patients. METHODS: Between September 2007 and August 200
We consider a real valued function of a vector valued, differentiable, stationary Gaussian process and study an asymptotic expansion of the rate of level crossings as a parameter tends to infinity. We give explicit forms for the first and second terms in this expansion.
Om det lyckas att göra en av de idag viktigaste politiska frågorna, arbetslösheten, till ett individproblem, har makthavarna - de ekonomiska och politiska - också lyckats lyfta bort frågan om det kapitalistiska samhällets legitimitet från dagordningen.
The severity of urinary tract infection (UTI) reflects the quality and magnitude of the host response. While strong local and systemic innate immune activation occurs in patients with acute pyelonephritis, the response to asymptomatic bacteriuria (ABU) is low. The immune response repertoire in ABU has not been characterized, due to the inherent problem to distinguish bacterial differences from hos
OBJECTIVES: Under physiological conditions the blood flow velocity waveform in the umbilical vein (UV) has an even non-pulsating pattern. Pulsations in the UV have been described in human fetuses exposed to chronic hypoxia and heart failure. Current techniques for fetal surveillance during labor and delivery involve a risk of both over- and underestimation of fetal hypoxia. We aimed to examine whe
Le présent travail veut s’inscrire dans une tradition de linguistique appliquée dont l’ambition consiste à allier théorie et empirisme. Lorsque l’on tâche de combiner deux domaines, on pourrait espérer qu’ils s’avèrent mutuellement enrichis ; Dans le meilleur des cas, la théorie permettrait non seulement l’élaboration d’hypothèses et de questions pertinentes sur les données mises en place par la d
The aim of this article is to propose a method for creating a more coherent concept of norms – and to deliver a tentative and open suggestion on how to define norms in a way that might fit into the context of Sociology of Law (further on shortened, SoL). The idea is that the norm concept can be chiselled out through ontological analysis, and that this analysis can be conducted in a way that allow
For MIMO systems, we introduce two novel architectures that significantly reduce the required number of expensive RF chains and still perform as well as a conventional full complexity solution for many cases of interest. We combine RF pre-processing - based solely on channel statistics and not instantaneous channel state - with selection and corresponding baseband signal processing. For a system w
