Determination of the Power Transmission Line Ageing Failure Probability due to the Impact of Forest Fire

open access: yes, 2018
With increased occurrences of forest fire, the short-term reliability of power transmission lines need to be re-evaluated considering the impact of forest fire on the aging of transmission lines.

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

open access: yesAnnals 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 ...

T1 Over Squared Proton Density Ratio to Characterize Multiple Sclerosis Lesions

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Differentiating remyelinated from demyelinated lesions in MS remains challenging without histological confirmation. This study introduces the T1‐to‐PD2 ratio (TPR) imaging approach and evaluates its ability to characterize MS lesions alongside other quantitative MRI (qMRI) metrics. Methods Thirty individuals with MS (mean age: 47.5 ±

Phase-mode transformation matrix application for transmission line and electromagnetic transient analyses

open access: yes, 2011
Frequency-dependent transmission line models can be developed in phase domain or in mode domain. Associated to these transmission line models, time domain or frequency domain can be used for electromagnetic transient analysis solutions.

Dielectric-filled 1 to 18 ghz coaxial slotted line [PDF]

open access: yes, 1986
The slotted line has, for a number of years, been one of the most useful and necessary tools in RF and microwave measurements. It was therefore felt appropriate to attempt to design an improved version, capable of broad band operation (1 to 18 GHz) with ...

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Transmission Lines

open access: yes, 2022
AbstractIn EMC, it is essential to understand the concept of transmission lines and when to apply it. Because once a signal interconnection line exceeds a critical length lcritical [m], impedance matching ( $$ \underline {Z}_{source}$$ Z

Narrow strip above ground plane transmission line formulation in the FDTD algorithm [PDF]

open access: yes, 2004
A number of thin wire formalisms for use in the FDTD method have been published over the years. One such formalism was published by Holland and Simpson (IEEE Trans., EMC-23, no. 2, pp. 88-97, 1981). Later, Ledfelt (Ph.D.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
