On June 24, 2020, the research team led by Prof. Jianzhong Xi from Peking University published an article named ‘Patient-Derived Tumor-Like Cell Clusters for Drug Testing in Cancer Therapy’ in Science Translational Medicine.
The group applied perovskite quantum dots with strong absorption, strong fluorescence, high charge mobility and high dielectric constant to organic solar cells (OSCs), which reduced energy loss and improved efficiency.
This award-winning paper gives a pioneer work in modeling and solving the physician recommendation problem with heterogeneous illness conditions of patients by using optimization theory, machine learning technology and statistical inference method.
They found that the transition from size-dependent to size independent yield strength of crystalline metallic materials is controlled by the competition between the stresses required for dislocation source activation and dislocation motion.
