Presuppositions are very important in our understanding of how background and context determine the interpretation of a sentence. However, if we study some of the things that have been claimed to be presuppositions, we find that it is a very miscellaneous collection of things. Here are some examples: (1) Harry saw the man kiss her presupposes that Harry and the man denote uniquely existing, for...

We introduce a fractional version of the illumination problem of Gohberg, Markus, Boltyanski and Hadwiger, according to which every convex body in R is illuminated by at most 2 directions. We say that a weighted set of points on Sd−1 illuminates a convex body K if for each boundary point of K, the total weight of those directions that illuminate K at that point is at least one. We define the fr...

Given r > 1, we search for the convex body of minimal volume in E3 that contains a unit ball, and whose extreme points are of distance at least r from the centre of the unit ball. It is known that the extremal body is the regular octahedron and icosahedron for suitable values of r. In this paper we prove that if r is close to one then the typical faces of the extremal body are asymptotically re...

AIM  The aim of this study was to systematically review the literature on the influence of enhanced recovery after surgery (ERAS) protocols and health related quality of life (HQoL) and patient satisfaction. METHOD A systematic review of the literature from January 1990 to February 2009 was undertaken. Studies were included if they compared HQoL and/or patient satisfaction after ERAS and conv...

BACKGROUND AND PURPOSE Robotic-assisted walking training after stroke aims to enhance the odd of regaining independent gait. Recent studies have suggested that this approach is more effective than conventional therapy alone only in severely affected patients. We determined whether these results persist at long-term follow-up. METHODS Forty-eight nonambulant participants after subacute stroke ...

Ninety seven patients with stroke who had participated in a randomised trial of conventional physical therapy nu an enhanced therapy for arm function were followed up at one year. Despite the emphasis of the enhanced therapy approach on continued use of the arm in everyday life, the advantage seen for some patients with enhanced therapy at six months after stroke had diminished to a non-signifi...

conclusions in this study, snpcr was specific and more sensitive than the chromogenic medium chromagar™ candida for the detection of candida spp. insofar as it failed to identify only a few isolates. materials and methods we used snpcr with universal and species-specific primers to detect candida species in the culture of clinical isolates. by using universal primers, we carried out the amplifi...

purpose: to compare visual outcomes and changes in high-order aberrations (hoas) following conventional versus customized photorefractive keratectomy (prk). methods: in this clinical trial, 58 eyes of 29 patients underwent myopic prk using the technolas 217z excimer machine. after comprehensive evaluation for refractive surgery, one eye of each participant randomly received conventional ablatio...

introduction: the purpose of this in vitro study was to compare the accuracy of the new electronic apex locator raypex5 with radiography for working length determination of straight and curved root canals. materials and methods: twenty straight and single canals of maxillary central teeth and twenty curved mesiobuccal canals of mandibular molar teeth were used. access cavities were prepared and...
