The theorem has generalizations to higher dimensions, and even has many variants in two dimensions. For example, one version states that among all polygons with k sides and a fixed perimeter, those that are perfectly symmetric (i.e., regular) have the greatest area. These area and volume optimization theorems are especially appealing because they offer physical insights into nature. They tell u...

Since its recent introduction into Europe, the yellow-legged hornet, Vespa velutina, has become a major predator of the domestic honeybee, Apis mellifera, but little is known about its hunting behavior. We studied V. velutina hunting behavior by a capture-mark-recapture procedure in an experimental apiary. A total of 360 hornets were captured and tagged, and we determined: (i) the number of hor...

BACKGROUND: Controlled trials have demonstrated the efficacy of antihistamines in the treatment of chronic idiopathic urticaria. Second-generation antihistamines are recommended as first-line therapy for chronic idiopathic urticaria. The purpose of this study was to determine the effect of desloratadine, a newer, nonsedating, second-generation antihistamine, on symptoms of chronic idiopathic ur...
