Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cognitive impairment, fatigue, and depression are common in multiple sclerosis (MS), potentially due to disruption of regional functional connectivity caused by white matter (WM) lesions. We explored whether WM lesions functionally connected to specific brain regions contribute to these MS‐related manifestations.

On the Weak Characteristic Function Method for a Degenerate Parabolic Equation
Journal of Function Spaces, 2019 For a nonlinear degenerate parabolic equation, how to impose a suitable boundary value condition to ensure the well-posedness of weak solutions is a very important problem.

Gaussian estimates for degenerate diffusion [PDF]
Proceedings of the American Mathematical Society, 2012 The author shows Gaussian estimates for the kernel of the semigroup generated by the operator \(m \Delta\) on the weighted Lebesgue space \(L^p(\Omega, m^{-1}(x) \, dx)\) for \(p \in [1,\infty)\) and bounded measurable functions \(m: \Omega \to (0,\infty)\) on arbitrary open sets \(\Omega \subset \mathbb{R}^N\). In the main result it is shown that if \(

SNUPN‐Related Muscular Dystrophy: Novel Phenotypic, Pathological and Functional Protein Insights
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective SNUPN‐related muscular dystrophy or LGMDR29 is a new entity that covers from a congenital or childhood onset pure muscular dystrophy to more complex phenotypes combining neurodevelopmental features, cataracts, or spinocerebellar ataxia. So far, 12 different variants have been described.

Entire solutions for a reaction–diffusion equation with doubly degenerate nonlinearity
Advances in Difference Equations, 2018 This paper is concerned with the existence of entire solutions for a reaction–diffusion equation with doubly degenerate nonlinearity. Here the entire solutions are the classical solutions that exist for all (x,t)∈R2 $(x,t)\in \mathbb{R}^{2}$.

Accelerated Progression of Gait Impairment in Parkinson's Disease and REM Sleep Without Atonia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective People with Parkinson's disease (PD) and rapid eye movement (REM) sleep without atonia (RSWA) often have more severe gait disturbances compared to PD without RSWA. The association between the presence and expression of RSWA and the rate of progression of gait impairment in PD is unknown.

Generalized Einstein relation for nonparabolic multiple energy-band degenerate semiconductors
AIP Advances, 2019 A generalized Einstein relation for electron gases of degenerate semiconductors with a system of typically two nonparabolic conduction band structures is derived and formulated in near-equilibrium condition based on using the semiclassical drift ...

Diffusion Tractography Biomarker for Epilepsy Severity in Children With Drug‐Resistant Epilepsy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To develop a novel deep‐learning model of clinical DWI tractography that can accurately predict the general assessment of epilepsy severity (GASE) in pediatric drug‐resistant epilepsy (DRE) and test if it can screen diverse neurocognitive impairments identified through neuropsychological assessments.
