An Extreme Point of Orlicz Spaces Equipped with Φ-Amemiya Norm

open access: yesJournal of Harbin University of Science and Technology, 2021
In Orlicz space,the formula of computation of a new norm that we call Φ-Amemiya norm is given. In this paper,we disscuss the conditions of norm attainability of the Orlicz space equipped with Φ-Amemiya norm, and the criterion of an extreme point is ...

The Maximum Principle for Variable-Order Fractional Diffusion Equations and the Estimates of Higher Variable-Order Fractional Derivatives

open access: yesFrontiers in Physics, 2020
In this paper, the maximum principle of variable-order fractional diffusion equations and the estimates of fractional derivatives with higher variable order are investigated.

An application of the Choquet theorem to the study of randomly-superinvariant measures [PDF]

open access: yesOpuscula Mathematica, 2012
Given a real valued random variable \(\Theta\) we consider Borel measures \(\mu\) on \(\mathcal{B}(\mathbb{R})\), which satisfy the inequality \(\mu(B) \geq E\mu(B-\Theta)\) (\(B \in \mathcal{B}(\mathbb{R})\)) (or the integral inequality \(\mu(B) \geq ...

Evaluating carbon-electrode dielectrophoresis under the ASSURED criteria

open access: yesFrontiers in Medical Technology, 2022
Extreme point-of-care refers to medical testing in unfavorable conditions characterized by a lack of primary resources or infrastructure. As witnessed in the recent past, considerable interest in developing devices and technologies exists for extreme ...

Strongly extreme points and approximation properties [PDF]

open access: yes, 2017
We show that if $x$ is a strongly extreme point of a bounded closed convex subset of a Banach space and the identity has a geometrically and topologically good enough local approximation at $x$, then $x$ is already a denting point. It turns out that such

Questions About Extreme Points

open access: yesIntegral Equations and Operator Theory, 2023
AbstractWe discuss the geometry of the unit ball—specifically, the structure of its extreme points (if any)—in subspaces of$$L^1$$L1and$$L^\infty $$L∞on the circle that are formed by functions with prescribed spectral gaps. A similar issue is considered for kernels of Toeplitz operators in$$H^\infty $$H∞.

𝐶*-extreme points [PDF]

open access: yesTransactions of the American Mathematical Society, 1981
Let A \mathcal {A} be a C ∗ {C^ \ast } -algebra and let S \mathcal {S} be a subset of A \mathcal {A} . S \mathcal {S} is C ∗ {C^ \ast

Extreme purifying selection against point mutations in the human genome

open access: yesNature Communications, 2022
Previous work has investigated selection in the coding genome, but it is not as well characterized in the non-coding genome. By analyzing rare variants in 70k genome sequences from gnomAD, the authors detect very strong purifying selection ...

Possible impact of urbanization on extreme precipitation–temperature relationship in East Asian megacities

open access: yesWeather and Climate Extremes, 2021
This study investigates the possible impact of urbanization on the summertime extreme precipitation–temperature (P–T) relationship in East Asia. The local climate in three megacity regions—Guangdong in China, Seoul/Gyeonggi in Korea, and Tokyo in Japan ...

On C$^*$-extreme points [PDF]

open access: yesProceedings of the American Mathematical Society, 2000
Summary: Each weak\(^*\) compact \(C^*\)-convex set in a hyperfinite factor (in particular in \(B({\mathcal H})\)) is the weak\(^*\) closure of the \(C^*\)-convex hull of its \(C^*\)-extreme points.
