Total Ring of fractions of skew PBW extensions [PDF]

open access: yes, 2014
We study the Gelfand Kirillov conjecture for some algebras and rings, we use similar tools for studying the ring of fractions of skew PBW extensions, establishing isomorphisms between algebras and rings.

Return of Research Results to Participants in Longitudinal Cohort Studies in Health Research: Findings From 24 Cohorts of the Amsterdam Cohort Hub

open access: yesHealth Expectations, Volume 29, Issue 5, October 2026.
ABSTRACT Background Returning research results to participants is increasingly recognised as part of participant‐centred health research. How this is implemented in longitudinal cohort studies is not yet well characterised. This study aims to provide a descriptive overview of current result return practices across diverse cohort studies in the ...

Oxygels: Tunable Phosphorescent Hydrogels for Cherenkov‐Excited Luminescence Imaging (CELI) of Oxygen

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 34, 11 September 2026.
Biocompatible hydrogels with covalently embedded near‐infrared phosphorescent probes enable local tissue pO2 quantification by means of Cherenkov‐excited luminescence imaging (CELI), where optical excitation occurs within tissues upon irradiation with high‐energy electron beams.

Understanding Mead Production Using Comprehensive Two‐Dimensional Gas Chromatography, Fermentation Kinetics, and Chemometric Analysis

open access: yesSEPARATION SCIENCE PLUS, Volume 9, Issue 9, September 2026.
Mead products brewed from five yeast strains at three honey concentrations were analyzed using comprehensive two‐dimensional gas chromatography. Across sample groups, 98 compounds were detected from 18 classes. The relationship between production variables and the final VOC profile of mead can contribute to consumer understanding of contents and health

Universal property of skew $PBW$ extensions

open access: yes, 2014
In this paper we prove the universal property of skew $PBW$ extensions generalizing this way the well known universal property of skew polynomial rings. For this, we will show first a result about the existence of this class of non-commutative rings.

Equivariant spaces of matrices of constant corank one

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract We classify all irreducible G$G$‐equivariant subspaces of Hom(V1,V2)$\operatorname{Hom}(V_1,V_2)$ of constant corank one, where G$G$ is a reductive group over an algebraically closed field of characteristic zero and Vi$V_i$ are irreducible representations.
