[ Research & Teaching Excellence | HKUST Researchers Develop New Model for Accurate Landslide Prediction with Applications in Sustainable Agriculture, Energy, Healthcare, and Beyond ] Navigating the unpredictable terrain of nature's changes, HKUST researchers pioneer a paradigm shift in accurate landslide prediction with the PUA-DEM model. From safeguarding agriculture to enhancing healthcare, their innovation transcends boundaries, illuminating the path towards a safer, more sustainable future. Under the visionary leadership of Prof. ZHAO Jidong, this groundbreaking model deciphers the intricate dance of granular behavior, reshaping our understanding of particle dynamics in various environments. With applications spanning from early landslide detection systems to revolutionizing pharmaceutical manufacturing, the implications are profound and far-reaching. Published in the esteemed Proceedings of the National Academy of Sciences (PNAS), this research heralds a new era of predictive precision, poised to mitigate the human impact of nature's formidable forces.
