A Gaussian Obstruction to Uniform Mesh Bounds for Differential Operators

We classify the nonzero finite-order differential operators with real polynomial coefficients that preserve hyperbolicity and retain a positive uniform fraction of additive zero mesh on the whole Laguerre-Polya class: they are exactly the nonzero scalar multiples of the identity....

Financial Technology, Digital Transformation and Higher Education Outcomes: Evidence from Saudi Arabia in Comparative Perspective (2019–2023)

Using comparative data for Saudi Arabia, Singapore, Australia, the United Kingdom, and the United States over 2019–2023, this study examines conditional associations between Financial Technology (FinTech), digital infrastructure, and higher-education outcomes. The empirical unit...

Structural Evolution and Chemical Incorporation Pathways in Wadsley-Roth Oxides

Abstract We investigate solid-state reaction pathways to high-temperature phase formation in the entropy-stabilized Wadsley-Roth Ti(NbxTa1–x)2O7 phases. We analyze and discuss thermodynamic and kinetic factors governing these processes in TiNb2O7, TiTa2O7, and Ti(NbTa)2O7. Diffra...

From non-profit to capped-profit: governance, trust and purpose in organisational transition

Purpose This study aims to examine how a mission-driven organisation navigates ethical commitments, stakeholder trust and governance challenges during a transition from non-profit to capped-profit status. This study addresses how such transitions reshape organisational purpose, l...

Beyond the Image: Advanced Ultrasound from Visualization to Quantitative and Precision Diagnosis

Ultrasound has always excelled at showing us what is there [...]

Environmental Pollution in Food Production and Pathways for Mitigation through Sustainable and Circular Approaches

Abstract Global food production is under increasing pressure to meet global food security demands while simultaneously reducing environmental burdens. This review critically evaluates air emissions, greenhouse gas (GHG) contributions, water pollution, and solid waste generation a...

The Care Protocol: Asymmetric Love, Structural Integrity, and the Refusal of the Padded Lie (Document 143 - Version 2.1: Half-Bridges, Shoot-Through, and the Physics of Grace)

Document 143 (Version 2.1 Expanded Edition) in the Monograph Series on Causal Inertia, Epistemic Governance, and Realization Grammar: THE CARE PROTOCOL: ASYMMETRIC LOVE, STRUCTURAL INTEGRITY, AND THE REFUSAL OF THE PADDED LIE(OMSORGSPROTOKOLLEN: DEN ASYMMETRISKE KJÆRLIGHETEN, STR...

Scripting WebArena: A Language-Model-Free Agent at 77.7%

LK-47.web is a WebArena agent with no language model and no learned weights. A grammar maps each task intent to one of the benchmark's 190 template identifiers and its slot values, and a hand-written plan of site skills carries the task out through the original, unmodified harnes...

Birch-Type-Reduced Carbazole Anions Enable Redox-Adaptive Super-Reducing Photocatalysis

Abstract Photocatalytic activation of inert chemical bonds is constrained by the redox potential of the catalyst. Here, we report a redox-adaptive photocatalytic strategy in which an electron-rich carbazole photocatalyst, CBZ6, functions as a molecular redox transformer through t...

The Influence of Rheological Properties on the Adhesiveness of Food Waste and Its Implications for Mechanical Separation

Abstract The viscoelastic and adhesive properties of food waste materials are critical factors influencing the efficiency of mechanical separation processes in waste management. This study investigated the moisture-dependent rheological behavior─specifically storage modulus in bo...

Toxicity Evaluation of Microplastics Exposure in Water Contaminated with Pyrene and Methyl Chlorpyrifos Using Daphnia magna

Abstract In freshwater environments, microplastics (MPs) have emerged as important organic contaminants vectors. This study investigates the individual and combined toxicity of microparticles of polystyrene (PS) and polylactic acid (PLA) with two contaminants of major concern in...

Sharp KL Convex Aggregation under Arbitrary Misspecification

We determine the optimal high-probability excess Kullback–Leibler risk for proper convex aggregation under arbitrary misspecification. The excess is measured relative to the best convex mixture of a dictionary of M densities. For n ≥ 1, M ≥ 2, and failure probability 0 < δ ≤ 1/2,...

Use of Ultralow Dosages of Graphene to Enhance the Microstructural and Mechanical Properties of 3D-Printed Cementitious Mortars

Abstract Three-dimensional (3D) concrete printing offers an economical and sustainable option for rapid, formwork-free construction of geometrically unique structures. However, 3D-printed concrete elements often suffer from print-induced anisotropy and reduced mechanical performa...

New Evidence of MnO x -Mediated Pb Sequestration by Estuarine Biofilms in a Sediment–Water Microcosm

Abstract Intertidal biofilms experience recurring Pb exposure due to pollutant accumulation and sediment remobilization, and yet the sources supplying Pb to biofilms and mechanisms governing its uptake remain ambiguous. Using biofilms from Sundarbans as a globally relevant model,...

Plasmonic Ag@ZIF-8 Monolith for Enhanced Visible-Light Photocatalytic Degradation of Methylene Blue

Abstract Water contamination by organic dyes remains a major environmental challenge due to their toxicity, persistence, and resistance to conventional treatment methods. In this study, a plasmonic silver-modified metal–organic framework monolith was successfully synthesized via...

Geopolitical conflict, global uncertainty and equity market resilience in the MENA region: evidence from a quantile machine-learning framework

Purpose This study aims to examines how global uncertainty and domestic geopolitical conflict affect equity market resilience in six Middle East and North Africa (MENA) economies across stress, normal and expansion regimes. Design/methodology/approach Using monthly MSCI country-i...

The Window Is Not the Subject: Language Models, Context, and the Limits of a Consciousness Claim

Language models, context windows, and consciousness are now spoken of as if they formed a single object: a system that attends over a long window and is, in virtue of that attention, aware. This article states the connection the preceding notes and the empirical literature actual...

Lean tools and Industry 4.0 technologies: a multidimensional analysis of firm performance

Purpose This study aims to examine how Lean/Lean Six Sigma (LSS) tools and Industry 4.0 (I4.0) technologies relate to firm performance across multiple dimensions and time horizons. Prior research has focused predominantly on productivity; the authors extend this view to profitabi...

From Gene-Based Breeding to Haplotype-Based Breeding for Rice (Oryza sativa) Improvement in the Genomics Era

Rice (Oryza sativa L.) improvement increasingly uses genome-scale variation, but breeding decisions remain trait-oriented and depend on genetic architecture, recipient background, target environment, and selection resources. This review assesses when phased haplotype information...
