BACKGROUND The headache phenotype and neurological symptoms of the German composer Richard Wagner (1813-1883), whose music dramas count towards the most frequently performed operas across the world, are previously undocumented. METHODS Richard Wagner's own descriptions of his headache symptoms in his original writings and letters are investigated, as well as the complete diary records of his ...

During the preparation of the Vascular Flora of the Marquesas Islands three new species of Coprosma (Rubiaceae, tribe Anthospermeae) have come to light and are described herein: Coprosma fatuhivaensis W. L. Wagner & Lorence, Coprosma meyeri W. L. Wagner & Lorence, and Coprosma temetiuensis W. L. Wagner & Lorence. Descriptions, illustrations, conservation status, and specimen citations are provi...

After a brief discussion of the Bogoliubov inequality and possible generalizations thereof, we present a complete review of results concerning the Mermin-Wagner theorem for various many-body systems, geometries and order parameters. We extend the method to cover magnetic phase transitions in the Periodic Anderson Model as well as certain superconducting pairing mechanisms for Hubbard films. The...

A study of coding to reduce the frequency of errors in communication systems which transmit data at a constant rate has been started. A new single-error-correcting code (the Wagner code) is described and analyzed. Its performance in a constant-data-rate system is evaluated and compared with Hamming's single-errorcorrecting code. The Wagner code is superior for many communication applications. I...

OBJECTIVE To assess the use of Wagner cementless self-locking stems for massive bone loss in hip arthroplasty. METHODS 22 patients with severe proximal femoral bone loss either due to prosthetic loosening or comminuted fracture were treated by Wagner cementless self-locking revision stems between November 1993 and June 1995. RESULTS Radiographic evidence of early bony incorporation was foun...

How well can one compress a dataset of points from a high-dimensional space while preserving pairwise distances? Indyk and Wagner have recently obtained almost optimal bounds for this problem, but their construction (based on hierarchical clustering) is not practical. In this talk, I will show a new practical, quadtree-based compression scheme, whose provable performance essentially matches tha...

Discussions and remarks about Jews and Judaism can be found throughout Nietzsche’s writings, from the juvenilia and early letters until the very end of his sane existence. But his association with antiSemitism during his lifetime culminates in the latter part of the 1880s, when Theodor Fritsch, the editor of the AntiSemitic Correspondence, contacted him. Known widely in the twentieth century fo...
