Current and Future Directions for Responsible Quantum Technologies: A ResQT Community Perspective

Abstract Quantum technologies (QT) are advancing rapidly, promising advancements across a wide spectrum of applications but also raising significant ethical, societal, and geopolitical impacts, including dual-use capabilities, varying levels of access, and impending quantum divid...

Joint Exploration of Neural Networks and Systolic Hardware for Improved AI Accelerator Performance

Abstract When executing common Neural Networks (NNs) on custom AI accelerators, the high performance suggested by advertised Giga or Tera Operations per Second (GOPS/TOPS) is typically not achieved, as low hardware utilization often leads to an effective performance in the single...

Food Security Versus Environmental Health: The Nitrogen Dilemma

ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the inf...

Self‐Assembled Hybrid Cell‐Enzyme Materials for Gas‐Powered Biocatalysis

ABSTRACT The integration of biological energy conversion into functional materials represents a key challenge in the development of advanced catalytic systems. Here, we introduce self‐assembled cell‐enzyme hybrid materials that integrate cellular metabolism with programmable enzy...

Automated Monitoring and Active Control of Jet-Breakup Ceramic-Pebble Fabrication

Abstract To meet the stringent dimensional tolerances required for lithium-enriched ceramic granules, the Karlsruhe Institute of Technology (KIT) has devised the KALOS (KArlsruhe Lithium OrthoSilicate) technique, in which a steady molten jet is deliberately destabilised by an adj...

On the Role of Al on the Microstructure Formation in Ti-rich Refractory Compositionally Complex Alloys

We gratefully acknowledge financial support by the Deutsche Forschungsgemeinschaft (DFG) with in the project 524725651 (KA 4631/6-1, HE 1872/45-1, and GO 2283/8-1). We acknowledge the chemical analysis by HCGE at the Institute for Applied Materials (IAM-AWP) by Dr. Bergfeldt, Kar...

Compound patterns and environmental drivers of typhoon disaster chains in southeast coastal China: a multiscale framework

Typhoons frequently trigger interacting hazards, including river flooding, urban waterlogging, landslides, and storm surge, but disaster records compiled at the event or administrative-unit level limit systematic analysis of their spatial co-occurrence and environmental different...

Quantitative measurement of aperture settings for generic camera calibration

Abstract We investigated the effect of camera aperture settings on the accuracy of generic camera calibration, extending previous work with a larger measurement range and slightly modified methods. Four hardware configurations were built: (I) a monitor-based intrinsic calibration...

Spatiotemporal Dynamics and Multi-Scale Diagnosis of Urban Resilience to Typhoon Disaster Chains in Fujian, China

Abstract Coastal cities in southeastern China face increasing threats from typhoon-induced compound disasters (for example, torrential rainfall, urban waterlogging, and storm surges) that can cascade into interconnected disaster chains under climate change and rapid urbanization....

Operationalized Self-Research with AI: A Conceptual Position Paper on Person-Specific Empirical Research in Elite Sport

Population-based evidence is indispensable in sport psychology but does not, by itself, establish how performance-relevant processes are organized within a specific elite athlete. This conceptual position paper develops Operationalized Self-Research with AI as a person-specific e...

Residual distribution predictive systems

Conformal predictive systems are sets of predictive distributions with theoretical out-of-sample calibration guarantees. The calibration guarantees are typically that the set contains a forecast distribution whose prediction intervals exhibit the correct marginal coverage at all...

Decoupling multistep schemes for elliptic–parabolic problems

We study the construction and convergence of decoupling multistep schemes of higher order using the backward differentiation formulae for an elliptic–parabolic problem, which includes multiple-network poroelasticity as a special case. These schemes were first introduced in [Altma...

Airborne measurements for investigating offshore wind farm wakes and modifications of sea state – benefits and limitations

Abstract. In the framework of the two large wind energy research projects WIPAFF and X-Wakes, crewed airborne measurements have been performed in and around wind farm clusters of the German Bight to investigate offshore wind farm wakes and associated sea-state modifications. Thes...

EditQL: A query language for evolving models

Abstract Context: Technically sophisticated systems are the result of the joint work of several domain experts. However, the more people collaborate, the more important it becomes to make the model evolution and its single edit operations accessible and comprehensible for involve...

Multimodal morphological characterization of the femoro-tibial joint of the black vine weevil ( Otiorhynchus sulcatus )

Abstract As open systems, arthropod joints and mechanical articulations face common challenges such as contamination and loss of lubricant. Recent studies suggest that insects manage these objectives of such open joints using a combination of cuticular microstructures and lubrica...

Mechanical Programming of PEGDA‐ β ‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

ABSTRACT Polyrotaxane‐based hydrogels with mechanically interlocked structures offer unique opportunities for designing biomaterials with tunable mechanical properties in tissue engineering. However, the polyrotaxane structure based on poly(ethylene glycol) (PEG) and β ‐cyclodext...

CO‐Adsorption on MgO Revisited: Polarization‐Resolved Identification of Step Edges as the Dominant Defects on MgO(100) and MgO(110)

ABSTRACT Magnesium oxide is a paradigmatic ionic oxide, yet its experimentally observed chemical activity remains difficult to reconcile with its wide band gap and non‐reducible character. Here, we combine polarization‐dependent infrared reflection–absorption spectroscopy with hy...

When LLMs Pass Tests but Fail the Process: Lessons from Governing a Multi-Agent Software Development Project

Software teams increasingly use large language models (LLMs) to plan, implement, and verify changes, but a passing test suite does not establish that the team built what was intended. This experience report describes an independent Ruby on Rails benchmark project in which a human...

Analysis of Thermohydraulic Spalling in Blended Cement Concrete

Abstract Recently, the construction industry has increasingly focused on the development of more sustainable transport infrastructure, such as tunnels, driven by the growing use of clinker-reduced cements. One major challenge in this context is fire exposure, which can lead to se...
