Involutive Nonassociative Lambek Calculus: Sequent Systems and Complexity [PDF]

open access: yes, 2017
In [5] we study Nonassociative Lambek Calculus (NL) augmented with De Morgan negation, satisfying the double negation and contraposition laws. This logic, introduced by de Grooté and Lamarche [10], is called Classical Non-Associative Lambek Calculus (CNL)

Local equivalence and refinements of Rasmussen's s‐invariant

open access: yesJournal 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.

On the incompatibility between two AIFS [PDF]

open access: yes, 2008
The purpose of this paper is to commence studying the incompatibility in the Atanassov's intuitionistic fuzzy sets framework. In order to do this, firstly we deal with the concept of T -incompatible sets, where T is an intuitionistic t- norm, relating it

CoRoFR: Community Detection of Feature Graph Improves Feature Selection Using Robust Fuzzy Rough Set

open access: yesAdvanced 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.

Resource modalities in game semantics [PDF]

open access: yes, 2007
The description of resources in game semantics has never achieved the simplicity and precision of linear logic, because of a misleading conception: the belief that linear logic is more primitive than game semantics. We advocate instead the contrary: that

Nonsymmetric Askey–Wilson Shift Operators

open access: yesStudies 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

Monadic Fragments of Intuitionistic Control Logic [PDF]

open access: yes, 2016
We investigate monadic fragments of Intuitionistic Control Logic (ICL), which is obtained from Intuitionistic Propositional Logic (IPL) by extending language of IPL by a constant distinct from intuitionistic constants.

Nonlinear Control of Inertial Response for HVDC‐Connected Offshore Wind Farms

open access: yesIET 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 Real K-Theory of Compact Lie Groups [PDF]

open access: yes, 2014
Let $G$ be a compact, connected, and simply-connected Lie group, equipped with a Lie group involution $\sigma_G$ and viewed as a $G$-space with the conjugation action. In this paper, we present a description of the ring structure of the (equivariant) $KR$

Stabilization of Chaotic Systems using Hardware‐in‐the‐Loop Validation for Sliding Mode Control and Input State Linearization

open access: yesThe 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.
