3D Surface Profiling via Direct End‐to‐End Regression With a Photonic Geometric Sensor

Laser &Photonics Reviews, EarlyView.
Measurements of microscale surface patterns are essential for quality control across semiconductor and biomedical industries, yet the development of miniaturized, intelligent systems remains constrained by the complexity and bulkiness of conventional benchtop metrology.

Reconfigurable Circularly Polarized Terahertz Emission from vdW Ferroelectric NbOI2

Laser &Photonics Reviews, EarlyView.
A controllable chiral terahertz pulse can be generated using a simple dual‐flake vdW ferroelectric NbOI2 emitter in which the polar axes of the two NbOI2 flakes are orthogonal. Both the chirality and the ellipticity can be manipulated by varying the separation distance and the orientations of their polar axes.

Beta‐Band and Aperiodic Activity Across New and Chronic Subthalamic Nucleus Deep Brain Stimulation in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Neurophysiological biomarkers in Parkinson's disease (PD) are increasingly used for deep brain stimulation (DBS). Their long‐term utility is not clear, especially when transitioning to sensing‐guided DBS years post‐surgery. Objectives Beta‐band power, bursting activity, and periodic and aperiodic components of local field potentials
