Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking

open access: yesLaser &Photonics Reviews, EarlyView.
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Distinction and mutual Influences between Parkinson's Disease‐related and unrelated Chronic Pain

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Chronic pain (i.e. > 3 months) is a common nonmotor symptom in patients with Parkinson's disease (PD), but the attribution to PD is critical for further treatment. Objectives We explored the PD Pain Classification System (PD‐PCS) criteria for the diagnosis of PD‐related pain and mutual influences between PD‐related and PD‐unrelated ...
