Shared Genetic Effects and Antagonistic Pleiotropy Between Multiple Sclerosis and Common Cancers

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Epidemiologic studies have reported inconsistent altered cancer risk in individuals with multiple sclerosis (MS). Factors such as immune dysregulation, comorbidities, and disease‐modifying therapies may contribute to this variability.

Investigation of Impedance‐Based Protection Mechanisms for Dry‐Type Iron Core Reactors Under Core Saturation Conditions

open access: yesIET Electric Power Applications
This paper discusses the potential core saturation issue in dry‐type iron core reactors caused by power system harmonics and proposes a protection strategy based on variations in third harmonic impedance characteristics. First, an equivalent model of the

Harmonic current suppression method of virtual DC motor based on fuzzy sliding mode

open access: yesOpen Physics, 2023
In the operation of power grid, the low frequency subharmonics in power lines are easy to cause harmonic current problems. A harmonic current suppression method is constructed based on fuzzy sliding mode and virtual DC motor (VDC).

Topological aspects of nonlinear excitonic processes in noncentrosymmetric crystals

open access: yes, 2016
We study excitonic processes second order in the electric fields in noncentrosymmetric crystals. We derive formulas for shift current and second harmonic generation produced by exciton creation, by using the Floquet formalism combined with the Keldysh ...

Unraveling the Molecular Mechanisms of Glioma Recurrence: A Study Integrating Single‐Cell and Spatial Transcriptomics

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.
