Given the ongoing pandemic of Covid-19 which has had a devastating impact on society and economy, explosive growth biomedical literature, there been growing need to find suitable medical treatments therapeutics in short period time. Developing new can be expensive time consuming process. It practical re-purpose existing approved drugs put them clinical trial. Hence we propose CovidBERT, relatio...

Continuous counter-current extraction of rhenium from roasting dust leach liquor was carried out using a mixer-settler extractor. Tributylphosphate was used as the extractant diluted in kerosene. The effects of the flow rates and extraction stages number were investigated. The extraction efficiency was affected by the flow rates of the aqueous and organic phases, and its mechanism was qualitati...

Up to now, relation extraction systems have made extensive use of features generated by linguistic analysis modules. Errors in these features lead to errors of relation detection and classification. In this work, we depart from these traditional approaches with complicated feature engineering by introducing a convolutional neural network for relation extraction that automatically learns feature...
