The change of regional hydrodynamic field caused by coal mining process affects the multi-field process of the formation and evolution of mine water quality, which may lead to the pollution of the water environment in the coal mining area.Research on the driving mechanism of the hydrodynamic field and the method of quantitative calculation of key p

Rice mapping products were derived from Sentinel-1A and Landsat-8 OLI multi-temporal imagery over Northern Italy at the early stages of the 2015 growing season.A rule-based algorithm was applied to synthetic statistical metrics (TSDs-Temporal Spectra Descriptors) computed from temporal Mens Tank Tops datasets of optical spectral indices and SAR bac

Vast amounts of clinical and biomedical research data are produced daily.These data can help enable data driven healthcare through novel biomedical discoveries, improved diagnostics processes, epidemiology, and education.However, finding, and gaining access to these data and relevant metadata that are necessary to achieve these goals remains a chal
