Analytical Evaluation of Simulated Kidney-Disease Profiles: Comparison of a Portable Near-Infrared Spectrophotometer with a Benchtop FT-NIR

Chronic kidney disease (CKD) is commonly assessed using blood biomarkers such as creatinine, urea and albumin. This study compared a portable six-channel near-infrared (NIR) analyzer (miniNIR; 1300–2100 nm) with a benchtop Fourier-transform near-infrared (FT-NIR) instrument for t...

Two-Stage Combustion of Ammonia/Hydrogen Blends: An Experimental Approach to Low-Carbon Fuel Utilisation

This study presents an experimental investigation of a laboratory-scale two-stage RQL-based combustor burning NH3/H2 fuel blends at a thermal input of 8.0–8.5 kW and atmospheric pressure using fuels containing 70–100% ammonia by volume in the first stage and 80–100% in two-stage...

Federated EGA in the European and Global Human Data Ecosystem

This Federated EGA in the European and Global Human Data Ecosystem white paper sets out our vision for the future role of Federated EGA (FEGA) in supporting secure, responsible and FAIR reuse of controlled-access human data. It describes how FEGA has developed into an operational...

Critical minerals and investment frameworks: Formalizing the bankability framework

Private investment in critical mineral projects is arguably not scaling at the pace required to meet projected demand, despite adequate reserves and abundant long-duration capital. The binding constraint is bankability. A recent policy framework matches mineral market structure,...

Regional-Scale Multi-Hazard Assessment of Earthquake-Induced Road Network Disruption

Recent earthquakes have shown that earthquake-induced landslides and liquefaction can severely disrupt transportation systems and generate significant direct and indirect losses. Still, these secondary hazards are rarely incorporated into regional road-network disruption assessme...

From formation to identity: understanding the dynamics of entrepreneurial teams in incubation programs

Purpose This study aims to examine how entrepreneurial team formation and the development of entrepreneurial team identity unfold within incubated startups. It investigates whether incubation programs serve merely as external support or actively shape internal processes such as a...

Runtime Firmware Update for 32-Bit Microcontrollers with Instruction Cache Under Concurrent Task Execution

Smart sensor devices increasingly require remote firmware updates to deploy new functionality, security patches and algorithmic improvements without interrupting services. Runtime firmware updates remain a significant challenge in embedded sensing systems, particularly in real-ti...

Two-phase closed thermosyphon system with microstructured boiling surfaces: Steady-state and transient regimes analysis

This work presents the experimental evaluation of a Two-Phase Closed Thermosyphon (TPCT, 32 mm inner diameter and 125 mm total length) using HFE-7100 dielectric fluid, equipped with novel laser-fabricated microstructured evaporator surfaces and a see-through adiabatic section for...

Design and Early Industrial Deployment of a Digital Continuous Improvement System for Manufacturing

Manufacturing companies often register process deviations in operational systems while managing continuous improvement (CI) actions through separate spreadsheets, templates and meeting records. This fragmentation weakens traceability between detection, prioritisation, execution a...

Geospatial assessment of agrivoltaic feasibility in the Iberian Peninsula

This work investigates the feasibility of deploying agrivoltaic (AgriPV) systems in the Iberian Peninsula through an integrated geospatial assessment framework. The proposed methodology combines geospatial screening, agroclimatic and spatial datasets, crop suitability assessment,...
