RATIONALE Macrophage mannose receptor (MRC) is one of the few molecules known to be involved in lymphocyte trafficking via the lymphatic vessels. In endothelial cells of efferent lymphatics, it binds L-selectin on lymphocytes. In afferent lymphatics, MRC mediates trafficking of both normal and malignant L-selectin-negative cells to the draining lymph nodes. OBJECTIVE This work was designed to...

Abstract Question answering(Q&A) system is important for accelerating the landing of artificial intelligence. This paper makes an improvement on Q&A which uses method retrieval-machine reading comprehension (MRC). In retrieval phase, we use BM25 to recall some documents and split these into paragraphs, then reorder paragraphs according correlation with question, so as reduce number reca...

CE-MRC has been in use for the past 15 years and was reported to be a useful method in the evaluation of CSF disorders and hydrocephalus. The use of CE-MRC in conjunction with other MR imaging techniques has been shown to be effective in selected cases for the evaluation of several disorders of cerebrospinal system. CE-MRC has certain advantages over other cisternographic studies with fewer sid...

Financial named entity recognition (FinNER) is a challenging task in the field of financial text information extraction, which aims to extract large amount knowledge from unstructured texts. It widely accepted use sequence tagging framework implement FinNER tasks. However, such models cannot fully take advantage semantic Instead, we formulate as machine reading comprehension (MRC) problem and p...

BACKGROUND Manual assessment of muscle strength is often graded using the ordinal Medical Research Council (MRC) scale. The scale has a number of inherent weaknesses, including poorly defined limits between grades '4' and '5' and very large differences in the span of muscle strength encompassed by each of the six grades. It is not necessarily obvious how to convert a manual muscle test finding ...
