Models of visual cortex suggest that response selectivity can arise from recurrent networks operating at high gain. However, such networks have a number of problematic features: (i) they operate perilously close to a point of instability, (ii) small changes in synaptic strength can dramatically modify the degree of amplification, and (iii) they respond slowly to rapidly changing stimuli. Divisi...

Rosacea is a very common skin disorder in the clinical practice that primarily affects the convex areas of the face. Extrafacial rosacea lesions have occasionally been described, but extensive involvement is exceptional. In the absence of its typical clinical or histological features, the diagnosis of extrafacial rosacea may be problematic. We describe an unusual case of rosacea with very exube...

This paper identiies how object models, statecharts and interaction diagrams can be given a semantics in the Object Calculus of Fiadeiro and Maibaum. A compositional interpretation of object model and statechart diagrams is developed, with separate theories constructed for object instances, class managers and associations which are then combined using categorical constructions to yield a formal...

In this CME podcast, listen to experts discuss the case of Mr K, a healthy 28-year-old man who has never needed medical care previously. He has recently lost his job and developed a major depressive episode that has complicated features. The experts review his objective screening and monitoring instrument results as well as possible steps to take that will help alleviate Mr K's problematic symp...

This paper presents the first results on parsing the Penn Parsed Corpus of Modern British English (PPCMBE), a millionword historical treebank with an annotation style similar to that of the Penn Treebank (PTB). We describe key features of the PPCMBE annotation style that differ from the PTB, and present some experiments with tree transformations to better compare the results to the PTB. First s...
