Study on the Influence of Coil Placement on Pulsed Eddy Current Testing

Journal of Physics: Conference Series, 2023
Abstract The pipeline system of plant is installed with an insulation layer on the outer wall of the pipeline. Currently, the primary methods of detecting pipeline system is ultrasound and uradiographic testing, which require the removal of the outside layer before testing.

Directional Deep Brain Stimulation for Parkinson's Disease: Results of an International Crossover Study With Randomized, Double‐Blind Primary Endpoint

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objective Published reports on directional deep brain stimulation (DBS) have been limited to small, single‐center investigations. Therapeutic window (TW) is used to describe the range of stimulation amplitudes achieving symptom relief without side effects.

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Image-Based Feature Extraction Technique for Inclined Crack Quantification Using Pulsed Eddy Current

Chinese Journal of Mechanical Engineering, 2019
Existing eddy current non-destructive testing (NDT) techniques generally do not consider the inclination angle of inclined cracks, which potentially harms a larger region of a tested structure.
