Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Dystonia Scales for Children: Challenges and Obstacles in DBS Practice

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Dystonia in pediatric patients often coexists with other movement disorders and neurodevelopmental issues. Current rating scales for evaluating pediatric deep brain stimulation (DBS) candidates are not universally applicable and often require a non‐validated combination of the existing scales.

Coaxial Dipole Array With Switching Transmit Sensitivities for Ultrahigh Field MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate dipole antennas with electronically switchable transmit field patterns to improve flip angle homogeneity in ultra‐high field MRI. Methods Reconfigurable dipole elements that could produce two distinct electronically switchable B1+$$ {B}_1^{+} $$ field profiles were conceptualized and constructed. Eight such elements were

Characterization of Fuel Rods Supported by Dimple‐Less Spacer Grids and Subjected to Nonlinear Vibrations

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...
