Assessing the Frequency, Duration, and Spatial Extent of Summertime Extreme Dew Point Conditions in the Southeastern USA, 1973–2022

open access: yesAtmosphere
The population of the southeastern USA is exposed to frequent extreme summertime high heat and humidity and is thus vulnerable to the resulting human thermal stress.

Application of the matrix exponential kernel [PDF]

open access: yes, 1972
A point matrix kernel for radiation transport, developed by the transmission matrix method, has been used to develop buildup factors and energy spectra through slab layers of different materials for a point isotropic source.

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

open access: yesAnnals 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.

A sequential sampling strategy for extreme event statistics in nonlinear dynamical systems

open access: yes, 2018
We develop a method for the evaluation of extreme event statistics associated with nonlinear dynamical systems, using a small number of samples. From an initial dataset of design points, we formulate a sequential strategy that provides the 'next-best ...

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

open access: yesAnnals 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 ...

EXTREME POINTS AND STRICT CONVEXITY

open access: yesDemonstratio 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 ...

Analytical procedure for estimating reliability of randomly excited structures [PDF]

open access: yes, 1971
Analysis considers statistical variation of material strength and interactions between catastrophic and failure fatigue modes. Procedure employs concepts of fracture mechanics and extreme point processes associated with stationary narrow-band random ...

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

open access: yesAnnals 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 points, strongly extreme points and exposed points in Orlicz--Lorentz spaces

open access: yes
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 $ω$,
