We prove that among all triangles of given diameter, the equilateral triangle minimizes the sum of the first n eigenvalues of the Neumann Laplacian, when n 3 . The result fails for n = 2 , because the second eigenvalue is known to be minimal for the degenerate acute isosceles triangle (rather than for the equilateral) while the first eigenvalue is 0 for every triangle. We show the third eigenva...

Whether visual working memory (WM) consists of a common storage resource or of multiple subsystems has been a controversial issue. Logie (1995) suggested that it can be divided into visual (for color, shape, objects, etc.) and spatial WM (for location). However, a recent study reported evidence against this hypothesis. Using a dual task paradigm, Wood (2011) showed interference between shape an...

odontogenic tumors are derived from epithelial, ectomesenchymal and/or mesenchymal elements that are or have been a part of the tooth-forming apparatus. of all the odontogenic tumors, calcifying epithelial odontogenic tumor accounts for 1% of the cases. approximately 200 cases have been reported to date. there is no sex predilection, with a 2:1 predilection for the mandible, mostly in the premo...

infections of the cerebrospinal shunts and other neurosurgical structures are not uncommon in the clinical practice. these infections are mostly clinical emergencies carrying negative prognostic impacts on the patients as well as spending healthcare resources. the low pathogenicity nature of some implicated pathogens results in minimal physical signs that may complicate the diagnosis and mislea...

This study aims to determine how the right of compensation for death is transferable heirs. It agreed that harming a human body should warrant compensation. Even if it does not result in financial losses, considered an attack on body. Nevertheless, prevailing trend positive law still hesitates consider harm itself, requires On contrary, we find Islamic jurisprudence considers matter its natural...
