Persistent luminescence (PersL) materials exhibit thermal‐favored optical behavior, enabling their unique applications in security night vision signage, in vivo bioimaging, and optical anti‐counterfeiting. Therefore, developing efficient and color‐tunable PersL materials is significantly crucial in promoting advanced practical use. In this study, hexagonal Zr4+‐doped CsCdCl3 perovskite is synthesized...
Quantitative susceptibility mapping (QSM) provides a valuable MRI contrast mechanism that has demonstrated broad clinical applications. However, the image reconstruction of QSM is challenging due to its ill‐posed dipole inversion process. In this study, a new deep learning method for QSM reconstruction, namely xQSM, was designed by introducing noise regularization and modified octave convolutional...
Hyporheic exchange is one of the important physical processes that affect the flow condition of surface water–groundwater interaction zone, the restoration of water environment and the maintenance of ecological balance. The influence mechanism of clay lens on hyporheic exchange has not been well revealed by now. A two-dimensional sand tank was constructed to study the influence of low permeable clay...
