Learning similarity functions between image pairs with deep neural networks yields highly correlated activations of embeddings. In this work, we show how to improve the robustness of such embeddings by exploiting the independence within ensembles. To this end, we divide the last embedding layer of a deep network into an embedding ensemble and formulate training this ensemble as an online gradie...

Hospital Physician June 2007 51 Lumbar puncture is a common procedure performed for diagnostic, anesthetic, and obstetric purposes; however, up to one third of patients may experience headache after the procedure.1,2 In 1898, Bier was the first to report on post–lumbar puncture headache (PLPH) after he and his associates underwent lumbar puncture themselves and experienced headaches first-hand....

We generalize the concept of combinatorial nested set complexes to posets and exhibit the topological relationship between the arising nested set complexes and the order complex of the underlying poset. In particular, a sufficient condition is given so that this relationship is actually a subdivision. We use the results to generalize the proof method of Čukić and Delucchi, so far restricted to ...

OBJECTIVE To assess the safety and efficacy of various forms of analgesia and sedation for fracture reduction in pediatric patients in the emergency department, as observed in randomized controlled trials in pediatric populations. DATA SOURCES Cochrane Controlled Trials Register, CINAHL (Cumulative Index to Nursing & Allied Health Literature), and MEDLINE. The search terms "fractures," "manip...
