Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective The Gold Coast criteria permit diagnosis of amyotrophic lateral sclerosis (ALS) even without upper motor neuron (UMN) signs. However, whether ALS patients with UMN signs (ALSwUMN) and those without (ALSwoUMN) share similar characteristics and prognoses remains unclear.

A 73‐Year‐Old Man With Several Years of Difficulty Climbing Stairs and Frequent Tripping
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT A 73‐year‐old man presented with progressive weakness and atrophy predominantly affecting the distal finger flexors and quadriceps muscles. Electrophysiological studies demonstrated mixed myogenic and neurogenic features. Muscle MRI showed inflammatory changes, and muscle biopsy revealed granulomatous myositis with histologic features ...

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

Epilepsy‐Associated Variants of a Single SCN1A Codon Exhibit Divergent Functional Properties
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Pathogenic variants in SCN1A, which encodes the voltage‐gated sodium channel NaV1.1, are associated with multiple epilepsy syndromes exhibiting a range of clinical severity. SCN1A variants are reported in different syndromes, including Dravet syndrome, which is associated with loss‐of‐function, whereas neonatal/infantile‐onset ...

Extreme points of vector functions [PDF]
Proceedings of the American Mathematical Society, 1953 Several previous investigations have appeared in the literature which discuss the nature of the set T in n-dimensional space spanned by the vectors (fsdyl, , fsdgn) where S ranges over all measurable sets. It was first shown by Liapounov that if yui, . .* * pn are atomless measures, then the set T is convex and closed.

Sex Representation in US Stroke Clinical Trials: A Decade of Trends and Challenges
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Stroke remains a major cause of disability and mortality in the US, with significant sex‐based disparities, and females remain underrepresented in stroke clinical trials. We aimed to examine sex representation in US‐based stroke clinical trials, identify trial characteristics associated with higher female enrollment (≥ 50%), and ...

Statistics of Extreme Spacings in Determinantal Random Point Processes
, 2005 We study translation-invariant determinantal random point fields on the real line. We prove, under quite general conditions, that the smallest nearest spacings between the particles in a large interval have Poisson statistics as the length of the ...

On the extreme points of quantum channels [PDF]
, 2014 Let L(m,n) denote the convex set of completely positive trace preserving operators from C^{m x m} to C^{n x n}$, i.e quantum channels. We give a necessary condition for L in L(m,n) to be an extreme point.

Metric Spaces of Extreme Points
Theory and Applications of Categories, 2020 The well-known Arens-Eells embedding theorem asserts that a metric space can be isometrically embedded as a set of linearly independent vectors in a Banach space. This paper provides an improvement for compact metric spaces by showing the following result: Given a compact metric space \((X,d)\) of diameter at most \(2\), there exists a separable real ...

Cracking the Code: Genotype–Phenotype Correlation Models in Sarcoglycanopathies
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Sarcoglycanopathies are among the most severe limb‐girdle muscular dystrophies (LGMD), though milder presentations have been described. These diseases are primarily caused by missense variants, but the limited predictability of their effect on protein maturation, complex formation, and transport has hindered reliable genotype ...
