Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

Relationship Between Neurologic Symptoms and Signs and FMR1 Genotype in Premutation Carriers

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Fragile X‐associated Tremor/Ataxia Syndrome (FXTAS) is the most severe late‐onset condition caused by a premutation in the FMR1 gene, characterized by expanded CGG triplet repeats of 55–200. Clinical presentations of FXTAS, including gait ataxia, kinetic tremor, cognitive decline, and rare Parkinsonism, are linked to ...

Partitions of the polytope of Doubly Substochastic Matrices

, 2018
In this paper, we provide three different ways to partition the polytope of doubly substochastic matrices into subpolytopes via the prescribed row and column sums, the sum of all elements and the sub-defect respectively.

Predictive Ability of Plasma p‐tau217 for β‐Amyloid Status: A Prospective Multicenter Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Plasma tau phosphorylated at threonine 217 (p‐tau217) measured with fully automated platforms has shown high accuracy for Alzheimer's disease (AD) diagnosis, but real‐world multicenter data remain limited. We aimed to validate the diagnostic performance of p‐tau217 for identifying AD pathology in a real‐world multicenter cohort ...

Extreme and exposed points of L(^n l^2_∞ ) and L_s (^n l^2_∞)

Extracta Mathematicae, 2020
For every n ≥ 2 this paper is devoted to the description of the sets of extreme and exposed points of the closed unit balls of L(n l2∞ ) and Ls(n l2∞ ), where  L(n l2∞ ) is the space of n-linear forms on R2 with the supremum norm, and Ls(n l2∞ ) is the ...

Strongly Extreme Points and Middle Point Locally Uniformly Convex in Orlicz Spaces Equipped with s-Norm

Journal of Function Spaces, 2019
As is well known, the extreme points and strongly extreme points play important roles in Banach spaces. In this paper, the criterion for strongly extreme points in Orlicz spaces equipped with s-norm is given.

Remarkable Recovery After Delayed High‐Dose Methylprednisolone in a Rare Case of Penetrating Spinal Cord Injury

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Traumatic spinal cord injury (TSCI) caused by sharp‐force penetration is exceptionally rare, and the use of high‐dose methylprednisolone (MP) remains highly controversial, especially beyond the conventional 8‐h treatment window. This case report describes a 30‐year‐old male with acute incomplete TSCI following a knife stab wound to the right ...

Extreme contractions on finite-dimensional polygonal Banach spaces

, 2019
We explore extreme contractions between finite-dimensional polygonal Banach spaces, from the point of view of attainment of norm of a linear operator. We prove that if $ X $ is an $ n- $dimensional polygonal Banach space and $ Y $ is any Banach space and

EXTREME POINTS AND STRICT CONVEXITY

Demonstratio Mathematica, 1994
The authors recall the definitions of a 2-normal linear space and an extreme point on its ``unit cylinder'' (an analogue of the unit ball in a n.l.s.), then prove several characterizations of extreme points and show that a 2-normal space is ``strictly convex'' (according to an analogous definition of strict convexity) if and only if every point on the ...

Extreme points, strongly extreme points and exposed points in Orlicz--Lorentz spaces

In this paper, we investigate the extremal structure of the unit ball in the most general classes of Orlicz--Lorentz spaces. the characterizations of extreme points, strongly extreme points, and exposed points are given for Orlicz--Lorentz function spaces $Λ_{φ,ω}$ generated by an arbitrary Orlicz function $φ$ and a non--increasing weight function $ω$,
