AlGaN based deep ultraviolet light-emitting diodes (DUV LEDs) have wide applications in many fields, such as air and water purification, disinfection, and biochemical inspection. However, the wall ...

Full waveform inversion (FWI) is inherently an ill-posed inverse problem. Gradient preconditioning in FWI is crucial for improving the convergence and stability of the inversion process, as it helps ...
