Image Analysis and StereologyThe acquisition and transmission of magnetic resonance images are susceptible to noise, particularly impulse noise. Although the method based on the ℓ0-norm and overlapping group sparse total variation (ℓ0-OGSTV) is effective for impulse noise image ...

Improving Minimax Group Fairness in Sequential Recommendation
Training sequential recommenders such as SASRec with uniform sample weights achieves good overall performance but can fall short on specific user groups. One such example is popularity bias, where mainstream users receive better recommendations than niche content viewers.

On the group rings of abelian minimax groups, II: The singular case
Journal of Algebra, 2006 The author studies some properties of the prime ideals in the group ring \(kG\), where \(k\) is a finite field and \(G\) is an Abelian minimax group. Recall that an Abelian group \(G\) is minimax if \(G\) contains a finitely generated subgroup \(H\) such that \(G/H\) satisfies the minimal condition.

Engineering Reports, Volume 8, Issue 8, August 2026.This graphical abstract presents a lightweight and automated BiLSTM‐based Multi‐Cycle GAN framework for retinal blood vessel and optic disc segmentation in fundus images. Initially, fundus images undergo preprocessing, including green channel extraction, denoising, resizing, and dataset splitting.

Graph‐Based Generative Adversarial Network for Adaptive IoT Intrusion Detection
Engineering Reports, Volume 8, Issue 8, August 2026.The study introduces a hybrid graph‐based generative adversarial network (G‐GAN) that integrates adversarial learning with graph attention mechanisms to enhance intrusion detection in IoT environments. G‐GAN significantly improves accuracy and adaptability by reducing false alarms and detecting emerging threats in dynamic, heterogeneous IoT networks ...

Journal of Multi-Criteria Decision Analysis, Volume 33, Issue 2, August 2026.ABSTRACT The Flexible and Interactive Tradeoff Elicitation (FITradeoff) method is a Multi‐Attribute Decision‐Making (MADM) approach designed to capture the preferences of a Decision Maker (DM) while minimising cognitive effort. To reduce the frequency of interactions and optimise the preference elicitation process, this paper introduces an innovative ...

Existence result for the CR-Yamabe equation
Bruno Pini Mathematical Analysis Seminar, 2013 In this note we will prove that the CR-Yamabe equation has infinitely many changing-sign solutions. The problem is variational but the associated functional does not satisfy the Palais-Smale compactness condition; by mean of a suitable group action we ...

Existence and multiplicity of nontrivial solutions for double resonance semilinear elliptic problems
Electronic Journal of Differential Equations, 2002 We consider resonance problems at an arbitrary eigenvalue of the Laplacien. We prove the existence of nontrivial solutions for some semilinear elliptic Dirichlet boundary values problems. We also obtain two nontrivial solutions by using Morse theory.
