A set of n weighted points in general position in R d defines a unique regular triangulation. This paper proves that if the points are added one by one, then flipping in a topological order will succeed in constructing this triangulation. If, in addition, the points are added in a random sequence and the history of the flips is used for locating the next(More)
We propose a new multiframe algorithm to enhance the spatial resolution of frames in video sequences. Our technique specifically accounts for the possibility that motion estimation will be inaccurate and compensates for these inaccuracies. Experiments show that our multiframe enhancement algorithm yields perceptibly sharper enhanced images with significant(More)
AIMS/HYPOTHESIS An accurate molecular diagnosis of diabetes subtype confers clinical benefits; however, many individuals with monogenic diabetes remain undiagnosed. Biomarkers could help to prioritise patients for genetic investigation. We recently demonstrated that high-sensitivity C-reactive protein (hsCRP) levels are lower in UK patients with hepatocyte(More)
BACKGROUND AND AIMS Infections are a common and serious complication among patients with cirrhosis. We assessed the epidemiology, risk factors, and clinical consequences of bacterial infections in cirrhotic patients. METHODS In this multicenter prospective study, all patients with cirrhosis of liver with different infections were analyzed. Infections were(More)
The aim of this study was to report the analysis of a single-center experience with single-balloon enteroscopy (SBE). A retrospective analysis of patients with small-bowel disorder who underwent SBE procedure from February 2011 to February 2013 was carried out. A total of 40 patients underwent 48 SBE procedures. Antegrade and retrograde approaches were used(More)
INTRODUCTION Constipation may be primary or secondary. Pathophysiologic subtypes of primary constipation are dyssynergic defecation (DD), slow (STC), and normal transit constipation (NTC). Clinical subtypes are functional constipation (FC) and constipation predominant IBS (C-IBS). AIMS The objectives of this paper are to study the clinical profile,(More)
