Evaluation Bias in Cross-Context Generalization of EEG-Based Affective Computing: A Simulation Study

Cross-context accuracy in electroencephalography (EEG)-based emotion recognition is usually reported without the model-selection rule, chance-level test, or reliability reference needed to interpret it. We quantify the consequences in simulations with known ground truth and on re...

The α-Mooney–Rivlin model of hyperelasticity

Abstract We introduce the α-Mooney–Rivlin model, a three-parameter generalization of the classical Mooney–Rivlin law based on a new pair of α-dependent invariants for incompressible hyperelasticity. The model preserves the transparent two-term structure of the classical formulati...

On pseudo-arcs from normal rational curve and additive MDS codes

Abstract Let normal upper P normal upper G left parenthesis k minus 1 comma q right parenthesis P G ( k − 1 , q ) $\mathrm{PG}(k-1,q)$ be the left parenthesis k minus 1 right parenthesis ( k − 1 ) $(k-1)$ -dimensional projective space over the finite field double struck upper F S...

Hardware‐Native Gaussian Sampling With Probabilistic Ising Machines for Modern Communication Paradigms

ABSTRACT Modern communication systems increasingly shift computation to edge devices, where post quantum signing, generative AI and semantic communication must operate under strict energy, latency and memory constraints. A central bottleneck in these workloads is Gaussian samplin...

Spatial Stiffness Programming in Single‐Filament Material Extrusion Through Data‐Driven Thermal Foaming

ABSTRACT Material‐extrusion printing of variable‐stiffness structures typically relies on multi‐material architectures, which often suffer from poor interfacial bonding, increased fabrication time, material waste, and complex tool‐change operations. Here, we develop a data‐driven...

Development of Sustainable Mortars and Concrete with Marine Sediment, Sea Sand and Seawater: A Review on Cement Hydration, Mechanical Strength, and Durability

Concrete production consumes vast quantities of natural aggregate and potable water, while coastal dredging produces hundreds of millions of cubic meters of underutilized marine sediments and sea sand annually. This study aims to provide a review on recycling dredged marine sedim...

A systematic experimental investigation on the aerodynamic contribution to mooring tension response in floating offshore wind turbines

Quantifying the aerodynamic effects on mooring line tension is essential to distinguish wind-induced impacts from wave-driven dynamics and to improve the understanding of mooring system behaviour under coupled environmental loading conditions. The present work provides the first...

Towards an Integrated Threefold Maturity Model for Manufacturing SMEs: A Systematic Literature Review of Lean, Digital, and Sustainability Maturity Models

In light of the ongoing twin digital and green transitions, small and medium-sized manufacturing enterprises’ (SMEs’) performance and development should be reassessed using more holistic approaches, which include the use of (i) productivity (lean), (ii) digitalisation, and (iii)...

Is cross reality crossing the industry?

Abstract Cross Reality (CR) enables seamless transitions and collaboration between environments characterized by different degrees of virtuality, potentially offering new opportunities for the integrated use of Augmented Reality (AR) and Virtual Reality (VR) in industrial setting...

Extended reality visual language for professional contexts: a study on visual dissonance

Abstract Extended Reality (XR) is increasingly deployed in professional workflows, where adoption research has focused on hardware ergonomics and cybersickness. As these barriers are addressed, an open question concerns how such interfaces should be visually designed. Professiona...

Multi-source structural identification of undocumented historic bridges via 360°photogrammetry, operational modal analysis, and model updating

This paper presents a robust, ultra-low-cost, and fully non-invasive framework for the structural identification of undocumented and hard-to-reach historic bridges under severe data-scarcity conditions. The proposed methodology combines: (i) tethered spherical (360°) photogrammet...

A hybrid framework combining large language models and Shapley-based methods for explainable cyberbullying detection

Cyberbullying remains a pervasive threat across social media platforms, highlighting the need for reliable detection systems and transparent decision-making processes. This work presents a comprehensive framework for cyberbullying detection that integrates two complementary eXpla...

A Methodological Reference Framework for Identifying and Valuing Intangible Benefits in Cost–Benefit Analysis of Public Health Interventions

Cost–benefit analysis (CBA) is a primary tool for appraising public investments, yet its reliability weakens when interventions generate benefits that are intangible and difficult to monetize. The challenge is acute in public health, where outcomes such as reduced mortality and m...

Finite Element Analysis of Ultra-Short, Extra-Short, and Conventional Dental Implants in Fibula Free Flap Mandibular Reconstruction

Dental rehabilitation of fibula free flap mandibular reconstructions can be limited by the reduced vertical bone height available for implant placement. This study evaluated the biomechanical influence of ultra-short, extra-short, and conventional implants in a reconstructed fibu...

Tuning knowledge graph embeddings in clustering with LISE1

Knowledge Graph Embeddings are increasingly used in biomedical informatics to support similarity assessment, clustering, and knowledge discovery. Despite strong performance in link prediction, recent studies show that numerical proximity in embedding spaces does not always reflec...

A Critical Review of Thermo-Mechanical Behaviour of Reinforced 4D-Printed Shape-Memory Polymers

Abstract Additive manufacturing (AM) combined with smart materials has enabled 4D printing of structures capable of programmable, stimulus-driven shape transformation. Among these, particle-reinforced shape-memory polymers (SMPs) have emerged as a key platform for achieving enhan...

Dengue virus serotype classification from complete genomes using a Transformer with chunk-based sequence modeling and explainability analysis

Artificial intelligence is increasingly used for genomic surveillance of infectious diseases, but predictive models must be evaluated under realistic generalization settings and interpreted cautiously. We present XAI-DENFormer, an explainability-oriented framework for dengue viru...

Music Recommendation with Large Language Models: Challenges, Opportunities, and Evaluation

Music Recommender Systems (MRSs) have long relied on an information retrieval framing, where progress is measured mainly through accuracy on retrieval-oriented subtasks. While effective, this reductionist paradigm struggles to address the deeper question of what makes a good reco...

Fostering Circularity in the Stone Industry: Multi-Criteria Analysis of Existing Sustainable Indicators for Decision-Making Support

The stone industry generates substantial waste along the quarrying, cutting and finishing chain, with only about 22% of the extracted material processed into final products, while roughly 64% is lost as slurry and 8% as solid waste. Compared to other industries such as wood and s...

Biomimetic Rod-and-Plate Modeling for Bone Tissue Engineering

Abstract Bone tissues can be regarded as natural smart materials, capable of adapting to specific loading conditions through active remodeling processes, leading to micro-scale architectures characterized by optimized arrangements of rods and plates. The main goal of the proposed...
