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

Over 100 years ago August Bier performed the first recorded spinal anaesthetic; and complications from the use of regional anaesthesia have been described over this same period of time. Bier also being the first to describe a ‘spinal’ or ‘post dural-puncture headache’ [1]. In Great Britain a number of high profile legal cases in the 1950s concerning major complications of neuraxial techniques l...

Bier spots (BS) were first described in 1898 by Bier and detailed research by Lewis in 1927 [1,2]. There is no certain information about prevalence [2]. It is usually seen in people 20 to 40 years old young adults and is more common in women than man. Pediatric cases were reported [2]. BS are also called physiologic anemic macules, angiospastic macules, exaggerated physiologic speckled mottling...
