STUDY DESIGN Prospective cohort study. OBJECTIVE To identify factors that predict poor patient-reported outcomes in patients with traumatic vertebral body fracture(s) of the thoracic and/or lumbar spine without neurological deficit. SUMMARY OF BACKGROUND DATA There is a paucity of information on factors that predict poor patient-reported outcomes in(More)
Software frameworks which support integration and scaling of text analysis algorithms make it possible to build complex, high performance information systems for information extraction, information retrieval, and question answering; IBM's Watson is a prominent example. As the complexity and scaling of information systems become ever greater, it is much more(More)
Expert finding, aiming to answer the question: “Who are experts on topic X?”, is becoming one of the biggest challenges for information management. Much work has been conducted for expert finding. Methods based on language model, topic model, and random walk have been proposed. However, little work has studied why people want to find experts. In this work,(More)
In this paper, we present a topic level expertise search framework for heterogeneous networks. Different from the traditional Web search engines that perform retrieval and ranking at document level (or at object level), we investigate the problem of expertise search at topic level over heterogeneous networks. In particular, we study this problem in an(More)
With the Web content having been changed from homogeneity to heterogeneity, the recommendation becomes a more challenging issue. In this paper, we have investigated the recommendation problem on a general heterogeneous Web social network. We categorize the recommendation needs on it into two main scenarios: recommendation when a person is doing a search and(More)
BACKGROUND Fatty acid oxidation disorders may cause sudden and unexpected infant death and are associated with the histological hallmark of hepatic steatosis. The goal of the present study was to assess the value of post-mortem molecular analysis for medium-chain acyl-coenzyme A dehydrogenase (MCAD) and mitochondrial trifunctional protein (MTP) defects in(More)
