Comparing GenAI Summaries Versus Chatbots for Supporting Reflection in Healthcare Simulation

Reflection is critical for learning. In healthcare, simulations help learners practice clinical and teamwork skills, while reflection supports improving practice. Learning analytics (LA) dashboards can support reflection by visualizing activity data, but their effectiveness is li...

Operando and Postmortem Study of Iridium-Decorated Titanium-Based Catalysts in PEM Water Electrolysis

Abstract Understanding the dynamic degradation of oxygen-evolution electrocatalysts under realistic operating conditions is essential for advancing the performance and efficiency of proton exchange membrane (PEM) water electrolyzers. By combining operando Small-Angle and Wide-Ang...

Multimodal imaging reveals no evidence for magnetite-based magnetoreceptors in the mole-rat eye

Magnetoreception is widespread across animals, but its sensory mechanism remains unresolved. One leading hypothesis proposes that single-domain magnetite is coupled to mechanosensitive ion channels. In subterranean Ansell's mole-rats, such receptors have been proposed to reside i...

Promoting digital object sharing practices through data stewards

This poster is/was presented at Fellowship of the Data – International RDM Community Meeting 2026 Sharing of digital objects in research remains essential for scientific reproducibility and integrity[i]. Making research data available is increasingly recommended by funders and in...

Detection of load orientation effects in Lithium-ion batteries via electrochemical impedance spectroscopy

This study investigates the influence of load orientation effects on the impedance response of commercial lithium-ion prismatic cells. Electrochemical impedance spectroscopy (EIS) was performed during stepwise deformation using a cylindrical impactor oriented along the cell's X-d...

Open or Frontier? A Cost- and Energy-Aware Benchmark of Large Language Models for Software Vulnerability Detection

Large language models (LLMs) are increasingly applied to software vulnerability detection, but evaluations report accuracy while ignoring inference cost and energy and under-represent open-weight models relative to proprietary systems. We benchmark eight LLMs, three frontier, and...

Inducing Room Temperature Ferromagnetism in Phyllosilicates via Iron Implantation

Abstract The modulation of intrinsic two-dimensional (2D) ferromagnetism has attracted significant attention due to its potential applications in spintronics and magnetic field sensing. However, the limited availability of intrinsically magnetic 2D materials has driven the explor...

Atomistic framework for glassy polymer viscoelasticity across twenty frequency decades

Glassy polymers are central to engineering applications, yet their viscoelastic response over broad frequency and temperature ranges remains difficult to characterize. We extend non-affine deformation theory by incorporating a time-dependent memory kernel within the generalized L...

Automated Spin‐Assisted Layer‐by‐Layer Epitaxy Produces Highly Oriented Mixed‐Linker MOF Thin Films

ABSTRACT Control over crystallographic orientation in metal‐organic framework (MOF) thin films is crucial for exploiting their anisotropic properties in sensing, catalysis, and separation. Achieving reproducible, highly oriented films remains challenging, especially for mixed‐lin...

On non-negative operators in Krein spaces and their perturbations

Abstract One of the most important contributions of Heinz Langer in the area of operator theory in Krein spaces is the introduction of the notion of definitizable operators and the construction of the corresponding spectral function. In this note we obtain a new characterization...

Integrated co-simulation of PEM fuel cell systems for automotive applications: modeling, coupling, and system behavior

Abstract Detailed stack models and dynamic balance-of-plant (BoP) models each capture important aspects of proton exchange membrane (PEM) fuel cell systems but are limited when applied independently. While detailed stack models are computationally demanding for system-level inves...

Development of an Automated Inflection Point Detection Algorithm for Deformation Rate Analysis

Abstract Accurate estimation of in situ stresses is essential for safe design of underground civil and mining engineering structures. Traditional in situ stress measurement methods often require extensive time, resources, and access to test location. Moreover, with these methods,...

Bottom-Up Realization of a Type-II Organic/Transition-Metal Dichalcogenides Heterointerface: Pentacene on Monolayer WS2

Abstract Stacked van der Waals heterostructures based on transition-metal dichalcogenides (TMDs) exhibit a rich variety of exotic interfacial phenomena. Substituting one component with an organic semiconductor (OSC) enables the design of hybrid heterostructures with tunable funct...

GHG reduction potential of biomass gasification pathways: An Austrian life cycle emission analysis

Dual fluidized-bed gasification of biomass is one way to defossilize the Austrian energy system. Although this technology is yet to be implemented on an industrial scale, it shows potential in terms of e.g. feedstock flexibility and product range. The present study assesses the s...

Persona-prompted LLM agents achieve modest but genuine prediction of human social media reactions

Abstract Social media platforms mediate how billions form opinions and engage with public discourse. As autonomous AI agents increasingly participate in these spaces, understanding their behavioral fidelity becomes critical for platform governance and democratic resilience. Previ...

Rate-dependent mechanical–electrical–thermal abuse response of fresh and aged tabless 4695 cylindrical cells under radial indentation

Electrochemical aging can alter the mechanical abuse response of large-format cylindrical cells, but its effect under dynamic loading remains insufficiently resolved. This study compares fresh and aged tabless 4695 cells at 100 % State of Charge (SoC) under dynamic radial indenta...

Quantum-well metasurface for free-space-accessible enhanced nonlinear polarization

Abstract Nonlinear frequency conversion underpins important technologies such as telecommunications and quantum computation; however, weak nonlinearities and architectures that resist miniaturization currently limit devices’ efficiency and widespread adoption. Here we combine a b...

Qualitative changes in binocular rivalry experience with age

Abstract Binocular rivalry is a visual phenomenon that occurs when two dissimilar stimuli are presented to each eye. The perception alternates between dominance periods when one of the stimuli is perceived with brief transition periods in between, providing a unique window into t...

Equivalent Structural Stiffness for Settlement Analyses: A Practical Workflow Accounting for Cracking and Creep

Reliable settlement predictions require a consistent representation of both soil behavior and evolving structural stiffness. While advanced soil models are available in geotechnical analyses, reinforced concrete structures are commonly represented by linear elastic elements, negl...
