Elementary abelian subgroups: from algebraic groups to finite groups [PDF]

open access: yes
We describe a new approach for classifying conjugacy classes of elementary abelian subgroups in simple algebraic groups over an algebraically closed field, and understanding the normaliser and centraliser structure of these.

On representations of elementary subgroups of Chevalley groups over algebras [PDF]

open access: yesProceedings of the American Mathematical Society, 1995
It is shown that every nontrivial linear or projective representation of the elementary subgroup of a Chevalley group over an algebra containing an infinite field must have degree greater than or equal to the square root of the dimension of the corresponding Chevalley-Demazure group scheme adding 1 and the equality emerges only if ...

On maximal subgroups of free idempotent generated semigroups [PDF]

open access: yes, 2011
We prove the following results: (1) Every group is a maximal subgroup of some free idempotent generated semigroup. (2) Every finitely presented group is a maximal subgroup of some free idempotent generated semigroup arising from a finite semigroup.

Stage‐Dependent β‐Synuclein Links MRI and Cognitive Decline in Alzheimer's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Synaptic degeneration drives cognitive decline in Alzheimer's disease (AD), but synaptic biomarkers are scarce. Brain‐enriched β‐synuclein emerged as a synaptic damage marker. We investigated its diagnostic, prognostic, and structural correlates across the AD continuum.

On the closure of an elementary abelian 2-subgroup of a finite group [PDF]

open access: yesHokkaido Mathematical Journal, 2002
Let \(k\) be a field of two elements, let \(H\) be a finite group, let \(S\in\text{Syl}_2(H)\), let \(V\) be a \(kH\)-module (with \(| V|\) finite) and let \(t\) be an integer. Set \[ \begin{multlined}\mu_t(S)=\{ U\leq V\mid U\text{ is }S\text{-invariant and }U=\langle u\in U\mid\dim_k([u,A])\leq t\\ \text{for any elementary Abelian subgroup }A\text ...

CSF Cytokine Network Organization Predicts Progression Independent of Relapse and MRI Activity in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Progression independent of relapse activity is a major determinant of long‐term disability in multiple sclerosis, but its immunopathologic basis remains incompletely understood. We investigated whether relapse‐independent progression in radiologically stable relapsing–remitting multiple sclerosis is associated with distinct ...

Girls show better quality motivation to learn languages than boys: latent profiles and their gender differences

open access: yesHeliyon, 2020
Students' gender can have subtle long-term effects on students' motivation, engagement, and ultimate achievement in learning a new language. Given the current focus on motivation in primary and secondary schools in many Asian countries, understanding ...

Reserves, Injury Severity, and Outcomes in Traumatic Brain Injury: A CENTER‐TBI Observational Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Reserve refers to the brain's ability to maintain function after an injury and strongly relates to traumatic brain injury (TBI) outcomes. This study examined (1) whether associations between pre‐injury reserve proxies and outcomes differed across injury severity categories, and (2) whether the impact of injury severity varied across ...

The Comprehensive Live Cell‐Based Cytotoxicity Assay for Monitoring Disease Activity and Guiding Rescue Therapy in Acute Attacks of NMOSD

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuromyelitis optica spectrum disorder (NMOSD) is a devastating neurological disease that lacks serological biomarkers that can accurately reflect disease activity. We established a live cell‐based assay (LCBA) using serum with endogenous complement to quantify the overall cytotoxicity, offering a novel functional tool for monitoring
