Characterization of a Resistively Multiplexed SiPM Readout for Position-Sensitive Scintillating Fibre Radiation Detectors

Active stoppers based on scintillating fibres provide fast signal formation, fine segmentation and compact geometry. On the other hand, their implementation requires a readout that can handle many silicon photomultiplier channels and a wide range of light intensities. We present...

Bulk mesophases modeling of ferroelectric nematic liquid crystals

Abstract Ferroelectric nematic liquid crystals (FNLCs) are emerging materials that combine orientational order with spontaneous macroscopic polarization. They exhibit distinctive properties, such as polar domain formation, field-tunable textures, and strong electro-elastic coupli...

Strontium isotopic signatures and source apportionment in urban soils of Salgótarján: unraveling the impact of industrial emissions

Abstract Urban soil contamination is primarily associated with human activities, especially industrial by-products, which have introduced high concentrations of heavy metal(loid)s from diverse sources over centuries of city development. This study investigated the distribution of...

GPT-like transformer model for silicon tracking detector simulation

Abstract Simulating physics processes and detector responses is essential in high energy physics and represents significant computing costs. Generative machine learning has been demonstrated to be potentially powerful in accelerating simulations, outperforming traditional fast si...

Suppressing Deep Ion Trapping in TiO2 Electrochromics via Interfacial Engineering of WO3–Al2O3/VOx Heterostructures

Single-component metal oxide electrochromic films suffer poor charge utilization and deep-site ion trapping, giving non-uniform charge injection. Targeting heterostructure engineering rather than new material discovery, bare TiO2, TiO2/WO3, TiO2/WO3-Al2O3 and TiO2/WO3-Al2O3/VOx f...

Co-design of a wheelchair-mounted robotic arm for functional autonomy: a Cybathlon case study in user-driven assistive robotics

Abstract Background Wheelchair-mounted robotic arms may support functional autonomy for individuals with upper-limb disabilities, but their long-term usability remains limited by the difficulty of matching high-dimensional robotic control to heterogeneous motor capabilities, dail...

Evaluating fine-tuned, embedding-based, and zero-shot models for aspect-based sentiment analysis in South Slavic news

In the contemporary digital media landscape, the ability to automatically distill public opinion from a vast and continuous stream of information is highly important. Aspect-Based Sentiment Analysis (ABSA) offers this granular capability. In this work, we address a specific, indu...

From Climate Risk Assessment to Adaptation Priorities: A System-Wide Framework for Climate-Resilient National Energy Planning

National energy planning increasingly needs to account for climate risks, yet adaptation priorities in National Energy and Climate Plans (NECPs) often remain too generic to guide infrastructure, regulatory, and investment decisions. This paper develops a policy-facing framework f...

CuFe Bimetallic Electrocatalyst for Low-Voltage Formaldehyde-Assisted Dual Hydrogen Production

Abstract An effective strategy to lower the operating voltage and system cost of water electrolysis for green hydrogen production is to couple the hydrogen evolution reaction with a kinetically facile oxidation reaction instead of the oxygen evolution reaction. Formaldehyde oxida...

In situ ALD growth of ZnO thin films incorporating Cu nanoparticles for Solar-driven photocatalysis

This study investigates ZnO thin films incorporating copper nanoparticles (Cu NPs) as efficient photocatalysts for solar-driven wastewater treatment. The ZnO@Cu composite films were fabricated by in-situ integration of Cu NPs into the ZnO during atomic layer deposition (ALD) grow...
