Deep Learning Network‐Tailored Microenvironment Matching of 4D Bioprinting Bioactive Scaffolds for Bone Regeneration

Advanced Science, EarlyView.
A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.

Pollutant emission from fires at open-pit coal mines

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Existing coal mining technologies are associated with significant pollution of the natural environment, especially atmospheric air. On top of this, in the event of an emergency related to the spontaneous combustion of coal, this negative impact significantly increases.
