Econometric and machine learning spatially varying models for the mass appraisal of residential properties

The differences in predictive performance between econometric and machine learning (ML) spatially varying models for the mass appraisal of residential properties are largely unknown. Therefore, this article aims to identify the most accurate and precise model to serve as an autom...

Evaluation of mechanical properties and corrosion resistance of various coating systems used on tool steel in the mould industry

Abstract This paper presents a comprehensive assessment of the surface and functional properties of selected tool steels (1.2343, 1.2083, 1.2378 and Toolox 44) coated with BALINIT LUMENA, BALINIT CROVEGA, BALINIT CROMA PLUS and BALITHERM PRIMEFORM protective coatings. The researc...

Kombucha-Derived Bacterial Cellulose for Active and Biodegradable Food Packaging: Production, Modification, Performance, and Current Challenges

Kombucha fermentation generates two fractions of potential relevance to food-packaging applications: a fermented liquid containing organic acids, polyphenols and other metabolites, and a cellulose-rich pellicle formed by cellulose-producing acetic acid bacteria. However, the ferm...

Optimization of platelet concentrate inventory management using a simple standardized decision‐support model: A retrospective study from a Regional Blood Center

Abstract Background and Objectives Platelet concentrates (PCs) are difficult to manage because of their short shelf‐life and variable clinical demand. The aim of this study was to evaluate the impact of a modified platelet inventory management strategy at a Regional Blood Donatio...

Enhancing Engine Efficiency: The Impact of Different Brand Oils and Friction Modifiers on Fuel Consumption

Reducing fuel consumption to lower CO₂ emissions remains a crucial goal for the automotive industry. One effective approach to achieving this objective is reducing friction-related energy losses within the engine through the use of low-viscosity engine oils and friction-modifying...

AI-Authorship Accusations Against Human Discussants: A Pragma-Dialectical Account of Procedural Derailment

Abstract This paper offers a pragma-dialectical reconstruction of AI-authorship accusations directed at human discussants: the charge that a contribution is machine-generated or not attributable to a responsible participant. Such an accusation is best understood not as a factual...

AI-driven organizational change: a competency-based framework for classifying AI integration trajectories

Purpose This article proposes a competency-based framework for diagnosing organizational change trajectories driven by artificial intelligence (AI) integration. It extends a four-stage typology of AI-enabled organizational models by showing that each stage can be identified throu...

Influence of Triple-Layer Furcellaran-Based Films Enriched with Walnut Oil Emulsion and Walnut Green Husk Extract on Storage Quality of Cod Liver Oil

Triple-layer films based on furcellaran were designed. To give them antioxidant and UV barrier properties, an ethanol extract from walnut green husks (WGHE) was added to the third layer. In order to provide them with active and water vapor barrier properties, an emulsion based on...

Tracking the baryon number with nuclear collisions

Baryon quantum number is found to be conserved since baryogenesis in the early Universe. Conventionally, each fractionally charged valence quark is understood to carry one-third of a baryon number. An alternative hypothesis posits that baryon number is instead carried by a baryon...

Engineering Furcellaran/Xanthan Gum/Beeswax Composite Films Containing Spirulina via High-Shear Homogenisation: Structural and Physicochemical Properties

The growing demand for sustainable and functional packaging has driven the development of biopolymer-based films prepared from food-grade components with potential suitability for edible packaging applications. This study focused on the development and characterisation of furcell...

Energy Supply Shocks and Inflation in Central and Eastern Europe: Evidence from Bayesian SVARs and Local Projections

Energy price shocks have been the main drivers of inflation in Europe during the last decade. This paper examines cross-country differences in the transmission and magnitude of energy supply shocks in the Visegrád Group countries (Poland, Czechia, Hungary, and Slovakia) over the...
