Development of a Shock and Detonation Velocity Measurement System Using Chirped Fiber Bragg Gratings
Sensors, 2020 Dynamic measurements of shock and detonation velocities are performed using long chirped fiber Bragg gratings (CFBGs). Such thin probes, with a diameter of typically 125 µm or even 80 µm can be directly inserted into high-explosive (HE) samples

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity
Advanced Science, EarlyView.This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

Absorption measurement of layers or materials: How to calibrate?
Results in Physics, 2019 The knowledge of the absorption in the optical materials is important because it can generate problematic phenomena (distortion, depolarization, damage…) when high-power lasers are used.
