Blockchain‐Based AI Intelligent Systems in Healthcare: A Decentralized Federated Learning Framework With Zero Trust

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Artificial intelligence (AI), blockchain (BC), and federated learning (FL) offer significant potential for strengthening data privacy, security, and decentralized decision‐making in healthcare. However, healthcare AI systems remain vulnerable to adversarial threats, including data poisoning, Byzantine behavior, Sybil attacks, and unauthorized access ...

Technoeconomic Analysis of Energy Storage Technologies Applicable to Solar Off‐Grid Systems: A Review

Journal of Engineering, Volume 2026, Issue 1, 2026.
This study addresses a critical gap in the literature: a lack of comprehensive and consolidated reviews on existing energy storage technologies and their suitability for various applications. This study investigated the major classes and types of energy storage systems, examining their characteristics, functional principles, and practical applications.

Discrete Choquet Integral Based on Quasi‐Overlap Functions on Intuitionistic Fuzzy Sets and Its Application in Multi‐Class Ensemble Learning

Journal of Mathematics, Volume 2026, Issue 1, 2026.
As a extension of fuzzy sets, intuitionistic fuzzy sets play an essential part in processing uncertain information. Quasi‐Overlap functions have emerged in recent years as a tool for information aggregation. The combination of intuitionistic fuzzy sets with quasi‐overlap functions offers new methodologies for addressing uncertain information.

Convergence in ψ‐Density: Fundamental Properties and Approximation Theorems for Positive Linear Operators

Journal of Mathematics, Volume 2026, Issue 1, 2026.
We define a new convergence concept called convergence in ψ‐density. Let D be the class of strictly increasing, differentiable, and unbounded functions ψ : (0, ∞)⟶(0, ∞). We say that a sequence x = {xk} is convergent in ψ‐density to L if the limit limi⟶∞1/∑k=1iψ′k∑k≤i,k∈Bψ′k=0, where B≔B(ϵ)≔{k ≤ i : |xk − L| ≥ ϵ} for every ϵ > 0. If the function ψ∈D is

Anticomonotonicity for preference axioms: The natural counterpart to comonotonicity

Theoretical Economics, Volume 20, Issue 3, Page 831-855, July 2025.
Comonotonicity (same variation) of random variables minimizes hedging possibilities and has been widely used, e.g., in Gilboa and Schmeidler's ambiguity models. This paper investigates anticomonotonicity (opposite variation (AC)), the natural counterpart to comonotonicity. It minimizes leveraging rather than hedging possibilities.

Using the Choquet integral for the determination of the anxiety degree

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
One considers a group S of subjects and one uses the measured values of EEG waves and the levels of anxiety given by the psychologists for the members of S in order to construct a monotone measure µ.

Bi‐Level Graph‐Based Optimisation for Distribution Network Reconfiguration and Optimal Placement of TCLBS and DC Switches

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
In this research, we focus on optimizing the reconfiguration of the network with the aim of load shedding and maintaining critical load points during peak load periods. Our main problem is to find an optimal pattern for switch placement in the network, which simultaneously preserves important load points, reduces network losses, minimizes voltage ...

Put–Call Parities, absence of arbitrage opportunities, and nonlinear pricing rules

Mathematical Finance, Volume 34, Issue 4, Page 1242-1262, October 2024.
Abstract When prices of assets traded in a financial market are determined by nonlinear pricing rules, different parities between call and put options have been considered. We show that, under monotonicity, parities between call and put options and discount certificates characterize ambiguity‐sensitive (Choquet and/or Šipoš) pricing rules, that is ...

A systematic review of multidimensional relevance estimation in information retrieval

WIREs Data Mining and Knowledge Discovery, Volume 14, Issue 5, September/October 2024.
Aim of the systematic review and main findings. Abstract In information retrieval, relevance is perceived as a multidimensional and dynamic concept influenced by user, task, and domain factors. Relying on this perspective, researchers have introduced multidimensional relevance models addressing diverse search tasks across numerous knowledge domains ...

Displacement sensing based on microscopic vision with high resolution and large measuring range

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 18, Page 2840-2858, 15 September 2024.
Abstract Microimage strain sensing (MISS) is a novel piston‐type sensor based on microscopic vision. In this study, optical disc slice is used as information carriers to improve MISS. There are multiple pits on the surface of an optical disc. By using machine vision algorithms, the pits can be converted into digital information, making them scales for ...
