Glymphatic Dysfunction Reflects Post‐Concussion Symptoms: Changes Within 1 Month and After 3 Months
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Mild traumatic brain injury (mTBI) may alter glymphatic function; however, its progression and variability remain obscure. This study examined glymphatic function following mTBI within 1 month and after 3 months post‐injury to determine whether variations in glymphatic function are associated with post‐traumatic symptom severity ...

Power-efficient radio-over-fiber aided spatial modulation
2023 IEEE Photonics Conference (IPC), 2023 Spatial modulation (SM) is a multiple-input multiple-output technique, that is capable of providing energy efficiency and spectral-efficiency trade-off. Here, we propose an optically-controlled SM by invoking the radio over fiber based processing, for demonstrating enhanced power-efficiency and flexibility, on the expense of insignificant performance ...

Tunable Single-Longitudinal-Mode High-Power Fiber Laser
International Journal of Optics, 2012 We report a novel CW tunable high-power single-longitudinal-mode fiber laser with a linewidth of ∼9 MHz. A tunable fiber Bragg grating provided wavelength selection over a 10 nm range. An all-fiber Fabry-Perot filter was used to increase the longitudinal

Efficient single frequency fibre lasers using novel photosensitive Er/Yb optical fibres
, 1997 Boron- and germanium-doped highly photosensitive cladding is used in a novel design to achieve photosensitive Er/Yb-doped fibers, permitting short, strong gratings (length ~1cm, reflectivity >99%) to be written without hydrogenation.
