Formulation of the problem. Quantum computers (see, e.g., 5]) have a potential of speeding up computations in many important problems. For example: By using Grover's algorithm 3, 4], for any given error probability e 0 , we can search for an item in an n-item (un-sorted) database in (p n) steps (where checking that a given element is the desired one is counted as a single step). By contrast, th...

involvement; neither survived a year and both required thoracotomy to establish the diagnosis. In summary, the study by Cordier and colleagues includes all presentations of pulmonary amyloidosis and provides sufficient clinical detail for a practicing physician to classify properly and thereby permit optimal management of patients presenting with this uncommon manifestation of a disease whose p...

Initial discussions centered on diagnostic improvements for middle ear disease, auditory neuropathy spectrum disorder, tinnitus and presbycusis. Central to these discussions was the widely held view that the standard audiogram and its interpretation is ...
