An MRI biomarker for Parkinsonism has long been sought, but almost all attempts at conventional field strengths have proved unsatisfactory, since patients and controls are not separated. The exception is Spin-Lattice Distribution MRI (SLD-MRI), a tec

UVC LEDs exhibit high junction temperature (T J ) and voltage sensitivity, which influences their radiant power and lifetimes. This study of 275nm, 3-PAD UVC LEDs can be useful to estimate T J and emphasize the need for optimal thermal management.
