We consider a special class of art gallery problems inspired by wireless localization. Given a polygonal region P, place and orient guards each of which broadcasts a unique key within a fixed angular range. In contrast to the classical art gallery setting, broadcasts are not blocked by the boundary of P. At any point in the plane one must be able to tell whether or not one is located inside P o...

Dear Editor Isodicentric chromosome 15 [idic(15) or inv dup(15)] syndrome is a rare condition with distinctive clinical features, including developmental delay, hypotonia, epilepsy, and autism or autisticlike behavior [1]. These features can obscure a definitive diagnosis, which can only be obtained by chromosomal analysis. In a review of the types and incidence of marker chromosomes at a unive...

One strategy that has received less attention is the use of seasonings. This study's objective was to determine the impact of seasoning on vegetable selection, liking, and intent to purchase. We conducted a 3-week study in a public café on a university campus...

The purpose of this paper is to report three families in which there were children with pulmonary valvular stenosis, who were mentally dull and also had cafe-au-lait spots inherited as an autosomal dominant, as in von Recklinghausen's disease (VRD)....

Security and probability are both artefacts that we hope to bring increasingly within the reach of refinement-based Formal Methods; although we have worked on them separately, in the past, the goal has always been to bring them together. In this report we describe our ongoing work in that direction: we relate it to a well known problem in security, Chaum’s Dining Cryptographers, where the vario...

A 6-year-old boy diagnosed as anisometropic amblyopia, with only café-au-lait spots and a family history of neurofibromatosis, presented with decrease in vision in the both eyes. Dilated fundus examination showed epiretinal membrane in both eyes over the macula. He underwent successful surgical management of the epiretinal membrane.

La langue noire villeuse est une condition bénigne. C'est une modification de la couleur de l'aspect de la langue qui devient noire, sale, avec des papilles filiformes allongées.

Globally, only 500 cases have so far been reported, with only five cases reported in the Indian subcontinent. Rarely, Alagille syndro...
