A Neutrosophic Monte Carlo Framework for Modeling Indeterminate Participation and Cultural Impact in Tourism Service Quality of Ethnic Sports Events [PDF]

Neutrosophic Sets and Systems
Ethnic sports tourism involves complex cultural, social, and economic interactions, where uncertainty arises not only from randomness but also from incomplete and contradictory information. Classical probability models cannot fully capture these features.

Pentagonal 2D Altermagnets: Material Screening and Altermagnetic Tunneling Junction Device Application

Advanced Functional Materials, EarlyView.
From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

Joint Discrete Approximation by Shifts of Hurwitz Zeta-Function: The Case of Short Intervals

Mathematics
Since 1975, it has been known that the Hurwitz zeta-function has a unique property to approximate by its shifts all analytic functions defined in the strip D={s=σ+it:1 ...

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

Advanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Equivalents of the Riemann hypothesis involving the Gram points

Mathematical Modelling and Analysis
The Riemann hypothesis (RH) on zeros of the zeta-function $\zeta(s)$, $s=\sigma +it$, states that all zeros of $\zeta(s)$ in the strip $0< \sigma < 1$ lie on the line  $\sigma =1/2$. Several equivalents of RH are known.

Laplace's Method Revisited: Weak Convergence of Probability Measures

The Annals of Probability, 1980
Let $Q$ be a fixed probability on the Borel $\sigma$-field in $R^n$ and $H$ be an energy function continuous in $R^n$. A set $N$ is related to $H$ by $N = \{x \mid\inf_yH(y) = H(x)\}$. Laplace's method, which is interpreted as weak convergence of probabilities, is used to introduce a probability $P$ on $N$.

Ultrahigh‐Yield, Multifunctional, and High‐Performance Organic Memory for Seamless In‐Sensor Computing Operation

Advanced Functional Materials, EarlyView.
Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...

On Joint Approximation of Analytic Functions by Beurling Zeta-Functions

Mathematics
For j=1,…,r, let Pj be a system of generalized prime numbers, NPj the corresponding system of generalized integers, and ζPj(s), s=σ+it, the Beurling zeta-function. In the paper, we consider simultaneous approximation of a collection of analytic functions

WEAK CONVERGENCE OF PROBABILITY MEASURES ALONG PROJECTIVE SYSTEMS

Demonstratio Mathematica, 1993
The author generalizes the notion of weak convergence of probability measures to the case when each measure \(\mu_ \alpha\) of a net \(\{\mu_ \alpha\}\) of probability measures is defined on the Borel \(\sigma\)- algebra of a metrizable topological space \(\Omega_ \alpha\) and the system \(\{\Omega_ \alpha\}\) forms a projective system of topological ...

Convergence of compound probability measures on topological spaces [PDF]

Colloquium Mathematicum, 1994
Let \(X\) and \(Y\) be topological spaces. We present a sufficient condition imposed on transition probabilities that assures the weak convergence or the relative compactness of compound probability measures \(\mu \circ \lambda\) defined by \(\mu \circ \lambda (D) = \int_X \lambda (x,D_x) \mu(dx)\) for a measure \(\mu\) on \(X\) and a transition ...
