Understanding Further the Phenotypic Spectrum of Central Nervous System Inflammatory Demyelinating Disorders Using Unsupervised Clustering

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Central nervous system (CNS) inflammatory demyelinating syndromes, including multiple sclerosis (MS), aquaporin‐4 antibody–positive neuromyelitis optica spectrum disorder (AQP4 + NMOSD), and myelin oligodendrocyte glycoprotein (MOG) antibody–associated disease (MOGAD), occasionally overlap.

Doctoral thesis "Affine geometry of space curves and homogeneous surfaces" [PDF]

open access: yes, 2012
We investigate the centroaffine space curves with constant centroaffine curvatures in R3. We classify them and give their explicit expressions. Moreover, we find out each centroaffine space curve with constant centroaffine curvatures can be written as ...

Association Between Motor Pathway Damage and Motor Deficit in Upper and Lower Limb in People With MS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Corticospinal tract damage is common in people with MS, but the degree of clinical symptoms varies. We hypothesize that corticospinal tract lesions are more extensive and severe in people with MS with motor impairments in both upper and lower limbs.

HOMOGENEOUS SPACE FIBRATIONS OVER SURFACES

open access: yes, 2017
By studying the theory of rational curves, we introduce a notion of rational simple connectedness for projective homogeneous spaces. As an application, we prove that over a function field of an algebraic surface over an algebraically closed field, a ...

Sex‐Stratified Association of Regional Dopamine Transporter Binding With Disease Progression in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To clarify the clinical relevance of dopamine transporter single‐photon emission computed tomography (DAT‐SPECT) abnormalities in amyotrophic lateral sclerosis (ALS), with a prespecified focus on sex‐stratified associations with disease progression and short‐term prognosis.

Characterization of a homogeneous Orlicz space

open access: yesElectronic Journal of Differential Equations, 2017
In this article we define and characterize the homogeneous Orlicz space $\mathscr{D}^{1,\Phi}_{\rm o}(\mathbb{R}^{N})$ where $\Phi:\mathbb{R}\to [0,+\infty)$ is the N-function generated by an odd, increasing and not-necessarily differentiable ...

Immersing homogeneous spaces in euclidean space

open access: yesPublicacions Matemàtiques, 1982
In Trans. Am. Math. Soc. 213, 305-314 (1975; Zbl 0312.55020), \textit{K. Y. Lam} proves, among other things, an immersion result for the real flag manifold \(G_{{\mathbb{R}}}(n_ 1,...,n_ s)=O(n_ 1+...+n_ s)/O(n_ 1)x...xO(n_ s)\) where O(n) is the real orthogonal group. His result is a special case of the following more general observation.
