A New Type of Neutrosophic Set in Pythagorean Fuzzy Environment and Applications to Multi-criteria Decision Making [PDF]
, 2023 In this paper, we introduce the concepts of Pythagorean fuzzy valued neutrosophic set (PFVNS) and Pythagorean fuzzy valued neutrosophic (PFVNV) constructed by considering Pythagorean fuzzy values (PFVs) instead of numbers for the degrees of the truth ...

The Use of the Legendre Transform in Chemical Thermodynamics: A Powerful Tool
Israel Journal of Chemistry, Volume 66, Issue 2, March 2026.Starting from Gibbs’ formulation of internal energy, all thermodynamic potentials can be obtained via the Legendre transform, along with a mnemonic rule for their calculation and an analysis of the extensivity of internal energy, culminating in Euler's theorem, the Gibbs–Duhem equation, and the definition of chemical potential.

Local equivalence and refinements of Rasmussen's s‐invariant
Journal of Topology, Volume 19, Issue 1, March 2026.Abstract Inspired by the notions of local equivalence in monopole and Heegaard Floer homology, we introduce a version of local equivalence that combines odd Khovanov homology with equivariant even Khovanov homology into an algebraic package called a local even–odd (LEO) triple.

CoRoFR: Community Detection of Feature Graph Improves Feature Selection Using Robust Fuzzy Rough Set
Advanced Intelligent Systems, Volume 7, Issue 12, December 2025.In machine learning, features often function as communities in many tasks, especially in medicine. However, existing feature selection methods struggle to mine feature collaborations, which can boost predictive performance. Moreover, they are noise‐sensitive, leading to suboptimal feature selection and accuracy degradation.

Nonsymmetric Askey–Wilson Shift Operators
Studies in Applied Mathematics, Volume 155, Issue 3, September 2025.ABSTRACT We classify the shift operators for the symmetric Askey–Wilson polynomials and construct shift operators for the nonsymmetric Askey–Wilson polynomials using two decompositions of nonsymmetric Askey–Wilson polynomials in terms of symmetric ones. These shift operators are difference–reflection operators, and we discuss the conditions under which

Nonlinear Control of Inertial Response for HVDC‐Connected Offshore Wind Farms
IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.This article proposes a nonlinear control strategy specifically designed to enable robust inertial support under the grid frequency events. A detailed nonlinear model is developed for the entire system, including the wind turbine, DFIG converters, HVDC transmission system, and grid interface.

The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.This study explores the stabilization of chaotic systems by comparing sliding mode control and input state linearization applied to the Lorenz system. Both methods achieve system stability, but sliding mode control offers enhanced robustness and reduced chattering, making it more effective for controlling chaos under uncertainties.

Video denoising by fuzzy motion and detail adaptive averaging [PDF]
, 2008 A new fuzzy-rule-based algorithm for the denoising of video sequences corrupted with additive Gaussian noise is presented. The proposed method constitutes a fuzzy-logic-based improvement of a recent detail and motion adaptive multiple class averaging ...

Equivariant algebraic concordance of strongly invertible knots
Journal of Topology, Volume 17, Issue 4, December 2024.Abstract By considering a particular type of invariant Seifert surfaces we define a homomorphism Φ$\Phi$ from the (topological) equivariant concordance group of directed strongly invertible knots C∼$\widetilde{\mathcal {C}}$ to a new equivariant algebraic concordance group G∼Z$\widetilde{\mathcal {G}}^\mathbb {Z}$.

Rank‐expanding satellites, Whitehead doubles, and Heegaard Floer homology
Journal of Topology, Volume 17, Issue 4, December 2024.Abstract We show that a large class of satellite operators are rank‐expanding; that is, they map some rank‐one subgroup of the concordance group onto an infinite linearly independent set. Our work constitutes the first systematic study of this property in the literature and partially affirms a conjecture of the second author and Pinzón‐Caicedo.
