— In this paper we describe a novel approach to autonomous dirt road following. The algorithm is able to recognize highly curved roads in cluttered color images quite often appearing in offroad scenarios. To cope with large curvatures we apply gaze control and model the road using two different clothoid segments. A Particle Filter incorporating edge and(More)
BACKGROUND The evaluation of patients with abdominal discomfort is challenging and patient selection for endoscopy based on symptoms is not reliable. We evaluated the diagnostic value of fecal calprotectin in patients with abdominal discomfort. METHODS In an observational study, 575 consecutive patients with abdominal discomfort referred for endoscopy to(More)
BACKGROUND European Panel on the Appropriateness of Gastrointestinal Endoscopy (EPAGE) criteria have been developed to increase diagnostic yield, but their predictive value is limited. We investigated the incremental diagnostic value of faecal calprotectin to EPAGE criteria. METHODS In a post-hoc analysis of a prospective study, EPAGE criteria were(More)
We present new experimental evidence on heterogeneity in the formation of inflation expectations and relate the variation to economic literacy and demographics. The experimental design allows us to investigate two channels through which expectations-formation may vary across individuals: (1) the choice of information and (2) the use of given information.(More)
BACKGROUND Fresh-frozen plasma (FFP) may contain antibodies to hepatitis B surface antigen (HBsAg, anti-HBs). These anti-HBs may lead to a misinterpretation of the actual hepatitis B immune status. Furthermore, they may not only confer protection against hepatitis B virus (HBV), but may also favor the selection of HBsAg mutants. CASE REPORT We report a(More)
