The language of radiology is rich with descriptions of imaging findings, often metaphorical, which have found common usage in the day-to-day practice of genitourinary radiology. These “classic signs” give us confidence in our diagnosis. Some of the signs have become so familiar to us that they are referred to as an “Aunt Minnie.” When the sign is invoked, or an Aunt Minnie is recognized, it oft...

The Software Engineering Volume is part of the IEEE-CS/ACM Computing Curriculum effort that began in the Fall of 1998 when individuals from the IEEE Computer Society and the ACM formed a Steering Committee and began work on the Computer Science Volume. This Steering Committee came to the conclusion that the area of computing had gone beyond the boundaries of computer science and that one volume...

How to efficiently map the nodes and links in a given virtual network (VN) to those in the substrate network (SN) so that the residual substrate network (RSN) can host as many VN requests as possible is a major challenge in virtual network embedding. Most research has developed heuristic algorithms with interactive or two-stage methods. These methods, however, could cause the RSN fragmented int...

The present study deals with the ecological impacts of the introduction of two alien species of piscivorous fish in several lakes of the Middle Rio Doce lake district in Minas Gerais, Brazil. It was demonstrated that these effects were not restricted only to the fish community. The introduction of the predatory red piranha Pygocentrus nattereri and the tucunaré Cichla cf. ocellaris caused not o...
