High-temperature bond performance of carbon and stainless steel reinforcement in concrete: A material-level experimental study with functional, economic and environmental approaches

The structural integrity of reinforced concrete structures is highly conditioned under extreme conditions depending on the adherence between steel and concrete. This research studies the behaviour at high temperatures (200 °C and 400 °C) and different cooling techniques, rapid (i...

A dual stream architecture integrating pathology foundation models for automated tumor region segmentation in Ki-67 assessment

The quantification of the Ki-67 proliferation index is a cornerstone in breast cancer prognosis and treatment planning. While deep learning has shown promise, traditional convolutional neural networks (CNNs) lack global context, and standard vision transformers struggle with loca...

Application of the W-shaped process for a Reinforcement Learning use case on drone navigation

The interest in Machine Learning (ML) has spread to safety systems due to its ability to solve tasks that cannot be explicitly programmed, including pattern recognition, object detection, and autonomous control. To ensure the safe integration of ML in avionics, the European Union...

Long‐Term Propagation Measurements in Madrid in a Q‐Band Satellite‐to‐Earth Link

ABSTRACT The Q/V band (40/50 GHz) is gaining interest as satellite operators will need larger bandwidth to be able to provide their services, which are experiencing an increasingly high demand. An accurate characterization of the satellite‐to‐Earth propagation channel is of param...

A general and robust 3D finite element dynamics framework for railway vehicle–bridge interaction with nonlinear wheel–rail contact modeling

Abstract A key challenge in 3D finite element models of coupled railway vehicle–bridge dynamics is the rigorous definition of kinematic constraints and the development of an efficient, robust solution. This paper presents a novel approach that can be implemented in general finite...

Spatial Multi-Feed Beam Steering Reflectarray Payload for Smallsats with Adapted Field of View

This work presents a spatial multi-feed beam steering reflectarray concept intended for compact small satellite payloads with adapted field of view (FoV) coverage. Unlike conventional reflectarray beam steering approaches based on tunable unit cells or mechanical reconfiguration,...

Balancing Hydrogen Bonding and Crystallinity in Enzymatically Functionalized Lignin–Poly(vinyl alcohol) Composite Films

Poly(vinyl alcohol) (PVA) is a promising biodegradable polymer; however, its reliance on petroleum and incompatibility with raw lignin additives hinder sustainable PVA composite development. In this study, mechanically robust PVA/functionalized acid-soluble lignin (fLGAS) composi...

EXPERIENCE MADRID—Sensory Cartography as a Tool for Exploring the Intangible Urban Landscape: A Pedagogical Experiment

Urban heritage documentation has traditionally privileged visual and material attributes, while transient and sensory dimensions of everyday urban experience remain more difficult to record through conventional architectural methods. This study examines sensory cartography as an...

A multi-level framework for capacity adjustment and flexible decision-making under data constraints in production planning and control

Abstract Capacity adjustment (CA) remains a persistent challenge in production planning and control (PPC), especially in workload-controlled environments where firms must regulate effective capacity through labor, machine, material, and inventory interventions. Analytical approac...

Coding protocol: provenance of quantified binding provisions in Trondheim statutory planning instruments

Deposited coding protocol for a single-case study of the provenance of quantified binding provisions in Trondheim, Norway. The protocol fixes, before any provision was coded: the unit of analysis; a three-kinds qualification separating binding-substantive from binding-procedural...

A Fuzzy Logic Model for Sustainable Water and Energy Resource Management in Mediterranean Greenhouses

Water scarcity, rising energy costs, and limited technology adoption challenge Mediterranean greenhouse horticulture. Although irrigation automation and digital decision-support tools have been widely studied, adoption barriers and integrated water–energy decision support are oft...

Multiuser immersive cultural experiences enabled by 5G, AI and free-viewpoint video

Extended Reality (XR) enhances cultural experiences by immersing users in virtual environments where virtual assets and 3D reconstructions provide a stronger connection to real-world scenarios. In this work, we present a platform for collaborative immersive cultural experiences,...

Volume Electron Microscopy of Cortical Organoids: Methods for Region Identification, Connectome Reconstruction, and Organelle Segmentation

Abstract Volume electron microscopy (vEM) has become a powerful tool for 3D ultrastructural analysis of neural circuits, yet its application to human brain organoids remains limited, particularly for connectomic studies. Here, we established a comprehensive and scalable workflow...

Unveiling the interactions between design optimization, modeling strategies, and spatial analysis in genomic selection

Abstract Key message Partially-replicated designs are more efficient than fully-replicated ones. They can be further enhanced through optimization and present positive synergy with fully-efficient models and 2D P-splines. Abstract In plant breeding, traditional field trials rely...

Probabilistic and Deterministic Seismic Hazard Assessments of the area comprised between west Gulf of Cádiz and east Alboran Sea

Abstract. The increased deployment of subsea infrastructures and the exploration of marine resources have heightened the need to assess seismic hazard on the seabed, especially in tectonically active offshore regions. The area between the Gulf of Cádiz and the Alboran Sea, which...

Local drivers and global suppliers of GHG emissions from the city of Madrid, 2010–2023

Despite its relevance for global mitigation, quantifying scope-3 emissions at the city level remains challenging. This study presents a consumption-based carbon footprint of Madrid over 2010–2023, integrating municipal data, regional supply and use tables, the FIGARO multiregiona...

Towards resilient forest establishment in Europe: functional traits, genetic diversity and multifunctional design

Abstract Forest restoration and afforestation across Europe are accelerating, yet the decision-making processes governing forest establishment remain unevenly examined, especially from a biodiversity perspective. Considering this and the global environmental changes of climate sh...
