The role of mesenteric angiography and embolization for massive gastroduodenal bleeding is unclear. We reviewed the records of patients who underwent angiography for acute, nonmalignant, and nonvariceal gastric or duodenal hemorrhage that was documented but not controlled by endoscopy. Fifty patients were identified over a 7-year period ending in March(More)
Pancreatic cystic neoplasms are uncommon, but it is important to differentiate them from pseudocysts and ductal adenocarcinoma. A retrospective review was performed to determine distinguishing characteristics and optimal treatment. In 51 patients operated on between 1981 and 1994 at a referral center, the following cystic neoplasms were found: 20 serous(More)
We present a framework for agent identity with a focus on structured cases and numerical levels of evidence and their handling. Our framework focuses on id-situations, where a person is judged to be the agent in some scenario, particularly a crime scene. An id-situation has a constellation of associated situations (providing what we call an id-case) to(More)
We are interested in how evidence in a case fits together to support a judgment about the identity of an agent. We present a computational framework that extends to the cyber world although our current work focuses on physical evidence from a crime scene. We take Barwise's situation theory as a foundation. Situations support items of information and, by(More)
This paper presents a computational framework for identity and is particularly focused on identifying the culprit in a crime-scene investigation. A case is conceptualized as a constellation of situations in the sense of Barwise’s situation theory. Data on a case is stored as RDF triples in a triple store. Several relevant OWL ontologies have been developed(More)
