The application of cosine similarity measures with Laplacian energy to q-rung orthopair fuzzy graphs in decision-making problems

Mohamed Atheeque A., Sharief Basha S., Nune Pratyusha, C. Raghavendra Reddy et al. • AIP Advances (2024)

Q-rung orthopair fuzzy sets (q-ROFS), which are better than the intuitionistic and Pythagorean fuzzy sets, are a significant tool for expressing ambiguous information. Their key feature is that their ability to represent a larger space of u...

Weak and strong forms of irresolute maps

Miguel Caldas Cueva • International Journal of Mathematics and Mathematical Sciences (2000)

We consider new weak and stronger forms of irresolute and semi-closure via the concept sg-closed sets which we call ap-irresolute maps, ap-semi-closed maps and contra-irresolute and use it to obtain a characterization of semi-T1/2 spaces....

Naturalism in Mathematics

Penelope Maddy (2000)

Abstract It is well known that certain natural statements of set theory, like Cantor's continuum hypothesis (CH), cannot be proved or disproved on the basis of the standard axioms (Zermelo–Fraenkel with Choice or ZFC). Some philosophers tak...

A game-theoretic sequential three-way decision using probabilistic rough sets and multiple levels of granularity

T. V. Soumya, M. K. Sabu • Discover Computing (2025)

Abstract The sequential three-way decision accepts additional information at each level and makes more accurate definite decisions with less uncertainty. This process can also be extended to two-way classification with the finer-grained inf...

On NeutroNilpotentGroups

Elahe Mohammadzadeh, Akbar Rezaei • Neutrosophic Sets and Systems (2020)

In this paper, we introduce the notion of commutator of two elements in a specific NeutroGroup. Then we define the notion of a NeutroNilpotentGroup and we study some of their properties. Moreover, we show that the intersection of two Neutro...

The Principles of Mathematics.

E. N., Bertrand Russell • The Journal of Philosophy (1938)

Published in 1903, this book was the first comprehensive treatise on the logical foundations of mathematics written in English. It sets forth, as far as possible without mathematical and logical symbolism, the grounds in favour of the view ...

Neurotoxicity of PM<sub>2.5</sub>-Bound Multi-Pollutant Mixtures in Parkinson’s Disease: Exploring the <i>INPP5D</i>/SHIP1-PI3K-AKT Axis via an Integrative Multi-Omics Study

Lufei Chen, Chaoxian Dai, Zhenfang Wu, Yuhan Lin et al. • Journal of Xenobiotics (2026)

Accumulating epidemiological evidence links ambient PM2.5 exposure to elevated Parkinson’s disease (PD) risk, yet the neurotoxicity triggered by PM2.5 multi-pollutant mixtures under real co-exposure scenarios remains insufficiently elucidat...

Computable phenotype for real-world, data-driven retrospective identification of relapse in ANCA-associated vasculitis

Vladimir Tesar, Conor Judge, John Kelleher, Zdenka Hrušková et al. • RMD Open (2024)

Objective ANCA-associated vasculitis (AAV) is a relapsing-remitting disease, resulting in incremental tissue injury. The gold-standard relapse definition (Birmingham Vasculitis Activity Score, BVAS&gt;0) is often missing or inaccurate in re...
