The large design space of modern computer architectures calls for performance modelling tools to facilitate the evaluation of different alternatives. In this paper, we give an overview of the Mermaid multicomputer simulation environment. This environment allows the evaluation of a wide range of architectural design tradeoffs while delivering reasonable simulation performance. To achieve this, s...

The cloaca/urogenital sinus and its adjacent region differentiate into the urogenital/reproductive organs. Caudal regression syndrome (CRS; including mermaid syndrome), a type of severe cloacal malformation displays hindlimb fusion and urogenital organ defects, thus suggesting that such defects are caused by several morphogenetic alterations during early development. The attenuation of bone mor...

Such imaginative descriptions will have been influenced by mythical beliefs in sirens and mermaids. The Greek sirens were singing bird-women who lured sailors to their death, as described by Homer (I945 :c. Iooo B.C.) in the Odyssey and interpreted in terms of classical religious mythology by Robert Graves (I955). TIhe mermaid or water-nymph type of siren of nautical tradition originates in the...

Sirenomelia or "mermaid syndrome" is a rare congenital syndrome characterized by the anomalous development of the caudal region of the body. We present a case of sirenomelia diagnosed in the first trimester using two-dimensional and three-dimensional ultrasonographic examination. A nulliparous woman aged thirty years was referred to our perinatology unit for evaluation because of oligohydramnio...
