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 ...

Iron Losses Prediction with PWM Supply Using Low and High Frequency Measurements: Analysis and Results Comparison [PDF]

, 2008
In this paper, two different methods for iron loss prediction are analyzed. The first method is based on the classical separation of loss contributions (hysteresis, eddy-current, and excess losses).

Research on Transient Electromagnetic Field and Eddy Current Losses Reduction in End of Large-Capacity Synchronous Condenser During UHVDC System Faults

IEEE Access
During the fault process of the ultra-high voltage direct current (UHVDC) system, the winding of the large-capacity synchronous condenser (SC) generates strong impulse current, leading to excessive eddy current losses and easily causing local overheating

Conducting Plate’s Eddy-Current Losses

Elektronika ir Elektrotechnika, 2004
It is assumed that all electromagnetic processes vary in a harmonic way in the laminated corner of the transformer’s magneticsystem.It is proved that due to technological air-gaps existing in the laminated corners of power transformers’ magnetic systems,additional eddy-currents originate which are distributed unevenly because of the skin-effect ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
