Hybrid Oxygen Enrichment and Preheating Strategy for Performance Recovery in Ultra‐Lean Micro–Trapped Vortex Combustors

Energy Science &Engineering, EarlyView.
Ultra‐lean H2 micro‐combustor performance is boosted through regulated O2 enrichment and inlet preheating. A 16‐case Taguchi study (ϕ = 0.3) shows: controlled enrichment and heating increase radiative output and efficiency, but excessive O2/temperature causes flashback.

Biological aspects and population dynamics of the European pilchard Sardina pilchardus (Walbaum, 1792) in the southeastern Mediterranean waters

Journal of Fish Biology, EarlyView.
Abstract The European pilchard, Sardina pilchardus, is a key small pelagic fish sustaining Mediterranean ecosystems and fisheries. This study represents the first comprehensive biological and population dynamics assessment of the European pilchard by applying the length‐based spawning potential ratio (LB‐SPR) approach to S.

Stability by Krasnoselskii's theorem in totally nonlinear neutral differential equations [PDF]

Opuscula Mathematica, 2013
In this paper we use fixed point methods to prove asymptotic stability results of the zero solution of a class of totally nonlinear neutral differential equations with functional delay. The study concerns \[x'(t)=a(t)x^3(t)+c(t)x'(t-r(t))+b(t)x^3(t-r(t))

Intentionality and Attentionality Dynamics in an Institutional Change Process

Journal of Management Studies, EarlyView.
Abstract In this article, we explore how actors' intentionality emerges, develops, and co‐evolves with institutional change. Although intentions are essential in shaping institutional change agents' motivations and actions, our understanding of their dynamics is limited and biased by the assumption that intentions are usually identifiable prior to ...

First‐Principles Structure–Activity Relationship Insights Into Phenolic Scaffolds: QSAR Modeling and Drug‐Likeness Screening

Advanced Theory and Simulations, Volume 9, Issue 2, February 2026.
Integrated machine learning framework for phenolic derivatives: classification (toxicity) and regression (logP) models identify top drug‐like compounds. Random Forest outperformed for toxicity, while Linear Regression best predicted logP. A weighted scoring approach prioritized five safe, lipophilicity‐optimized candidates, supporting rational ...
