MOGAD Is the Most Common Cause of Isolated Optic Neuritis in Children

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives The study aimed to characterize the clinical features, etiologies, and outcomes of isolated, first‐time pediatric ON in the post‐MOG‐IgG era. Methods This was a single‐center retrospective cohort study at Texas Children's Hospital of patients diagnosed with first‐time ON between 2018–2024, with follow‐up data collected through 2025.

Potential use of optimal polarisations in sensing the canting angle distribution of raindrops

open access: yesElectronics Letters, 1990
The optimal polarisation of rain backscatter is investigated to determine the Gaussian canting angle distribution of the raindrops. It is found that the COPOL MAX is sensitive to the canting angle distribution. The mean and variance of the canting angle distribution can be obtained from the average COPOL MAX and its spread.

Computational Fluid Dynamics Study on the Influence of Variable Cant Angle Winglets on Total Drag Reduction

open access: yes
The development of winglets has been motivated by the need to reduce lift-induced drag in aircraft. One of the main limitations, since they are fixed devices, is related to their inability in adapting to variable flight conditions. To address this issue,

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 ±

Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,
