– Exposure Core (Core A) Current understanding of air pollution effects on human health has been limited by the inability of available analytical methods to assess exposure to ambient multi-pollutant mixtures, which encompass both physico-chemical and spatio-temporal complexity. To address this problem, the Exposure Core will develop and employ new methodologies to assess short-and long-term ex...

Cystic pneumatosis intestinalis is a rare benign entity, characterized by intramural cysts located mainly in the intestinal wall. The etiology has not yet been elucidated, but generally it is associated with a systemic disease (1-4). Colonic pneumatosis represents about 30% of gastrointestinal cases (1). We present the case of a young girl with anorexia who underwent surgical treatment for cyst...

ARTMAP-FD extends fuzzy A R T M A P t o perform famaliarity discrimination. That is , the network learns to abstain from meaningless guesses on patterns not belonging to a class represented in the training set. ARTMAP-FD can also be applied in conjunction with sequential evidence accumulation. Its performance is illustrated here on simulated radar range profile data .
