Non-abelian extensions and Wells exact sequences of Hom-pre-Lie algebras

Mathematics Open
In this paper, we investigate non-abelian extensions of Hom-pre-Lie algebras and extensibility of pairs of automorphisms about non-abelian extensions.

Conceptualizing algorithmic inequality and future agenda. An annual review of information science and technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract The issue of inequality caused by algorithms, termed ‘algorithmic inequality’, has recently attracted scholarly attention in many disciplines due to its profound implications for society. While the body of literature on algorithmic inequality has grown, there remains a lack of comprehensive understanding of its nature, drivers, and impact ...

The epistemic ceiling: Veteran practitioners' perspectives on primary qualification entry standards for teaching secondary mathematics in Scotland

British Educational Research Journal, EarlyView.
Abstract This paper presents an exploratory analysis of contemporary curricular and professional qualification policies in the Scottish education system, focusing on minimum qualification thresholds for mathematics teaching. The study examines how veteran secondary mathematics practitioners perceive the structural and pedagogical implications of using ...

Structural Dynamics of the European Circular Economy Through a Consumption–Circularity–Efficiency Framework

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition toward a circular economy requires analytical approaches capable of capturing the interdependence between resource consumption, material circularity, and economic efficiency rather than assessing these processes through isolated indicators. This study develops and empirically evaluates the Consumption–Circularity–Efficiency (CCE)

Diagnostic Agreement and Threshold Correspondence Between Resting Full‐Cycle Ratio and Nicorandil‐Based Fractional Flow Reserve in Intermediate Coronary Stenosis: A Prospective Single‐Center Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background RFR has shown good aggregate agreement with FFR, including in prior Asian cohorts using intracoronary nicorandil. Where RFR‐FFR disagreement is concentrated relative to the FFR 0.80 decision boundary, and how the two binary thresholds correspond, remain incompletely characterized. Methods In a prospective single‐center registry, 300

Massive bigravity as a presymplectic BV-AKSZ sigma-model

Journal of High Energy Physics
We propose a presymplectic BV-AKSZ sigma model encoding the ghost-free massive bigravity theory action as well as its Batalin-Vilkovisky extension in terms of the finite-dimensional graded geometry of the target space.

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Algebraic approach to Rump’s results on relations between braces and pre-lie algebras [PDF]

Journal of Algebra and Its Applications, 2020
In 2014, Wolfgang Rump showed that there exists a correspondence between left nilpotent right [Formula: see text]-braces and pre-Lie algebras. This correspondence, established using a geometric approach related to flat affine manifolds and affine torsors, works locally. In this paper, we explain Rump’s correspondence using only algebraic formulae.
