Data Sovereignty, Stewardship, and Generative AI in Oral History: A Discussion Paper from the International Digital Oral History Lab

This working paper is issued by the International Digital Oral History Lab (https://idohl.org/) as part of its ongoing work on the responsible use of generative AI in oral history. It brings together evidence from oral history practice, AI governance, technical infrastructure, co...

Coordination-Controlled Stability of Pd Single-Atom Catalysts under Electrochemical Conditions

Abstract Single-atom catalysts (SACs) maximize atom utilization and site-specificity for diverse chemical and electrochemical transformations. While activity and selectivity have been optimized through advanced synthetic methods, the electrochemical stability of SACs remains insu...

Optical properties and shape-dependent retrievals of the imaginary part of the refractive index of freshly emitted Saharan dust

Abstract. Mineral dust is a major contributor to atmospheric aerosols and plays a complex role in Earth’s radiation budget. However, large uncertainties remain in quantifying its direct radiative effects (DRE), primarily due to poorly constrained absorption properties. Most estim...

The Xenoreactome: Where Foreign Chemistry Becomes Biological Organization

Abstract Biological systems can perform chemistry beyond their evolved reaction networks, but a reaction that is chemically possible does not necessarily occur in an intact system. I define the xenoreactome as the state- and reference-dependent network through which foreign chemi...

Atlas of geochemical, petrophysical and mechanical rock properties of the crystalline basement in Germany – first release

Abstract. A comprehensive and statistically robust understanding of rock characteristics is essential for reservoir characterization of the deep subsurface to accurately plan exploration campaigns, parameterize predictive 3D geological models, interpret geophysical data, and exec...

EXTENSION AND LIFTING OF G -BUNDLES FOR STACKS

Abstract We study extension properties for morphisms of stacks of bundles for group algebraic spaces. Applications are a short proof of the classification of bundles on the projective line for affine smooth group schemes whose identity component is reductive and the existence of...

Bounds on Treewidth via Excluding Disjoint Unions of Cycles

One of the fundamental results in graph minor theory is that for every planar graph $H$, there is a minimum integer $f(H)$ such that graphs with no minor isomorphic to~$H$ have treewidth at most $f(H)$. The best bound known for an arbitrary planar $H$ is ${O(|V(H)|^9\operatorname...

Land use intensification results in abrupt transitions between extensively and intensively managed grasslands

Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed. Further, these thres...

Assessment of adhesion and durability of laminated safety glass made from end-of-life float glass

Abstract As part of urban mining initiatives aimed at reducing waste, CO 2 emissions and the extraction of raw materials, the demand for sustainable resource recovery and repurposing of construction materials is growing. With many European buildings due to be renovated to meet cu...

Becoming the bull : Structural insights and engineering strategies for ultralong CDR ‐ H3 paratopes from cattle

Cattle produce a subset of antibodies (Abs) with unique architecture. These immunoglobulins feature an ultralong CDR-H3 (uCDR-H3) composed of up to about 70 amino acids that protrudes from the scaffold and folds into a distinct stalk-and-knob structure. The knob is a disulfide-ri...

Manufacturing Methodology for Single- and Multilayer Square Scintillating Fiber-Based Ribbons for Direct Coupling to Linear Photosensor Arrays

High-Energy and Nuclear Physics research facilities around the world demand cutting-edge instruments dedicated to exploring the signatures of particles knocked out by collisions at ultra-relativistic energies. Each instrument is a class of its own, but shares underlying technolog...

PRDTs: Composable Design and Verification of Consensus Protocols using Replicated Data Types

Consensus protocols are fundamental in distributed systems as they enable services with strong consistency properties. However, designing protocols optimized for specific use-cases under certain system assumptions is typically an error-prone process requiring expert knowledge. Fu...

Activity Recognition from Smart Insole Sensor Data Using a Circular Dilated CNN

Abstract Smart insoles equipped with pressure sensors, accelerometers, and gyroscopes offer a non-intrusive way of monitoring human gait and posture. We present an activity classification system based on a circular dilated convolutional neural network (CDCNN) that processes multi...

Return Temperature Prediction in District Heating Networks Using Primary Side Measurement Data

District heating networks are essential for decarbonizing the heating sector, yet their efficient operation is often hindered by high return temperatures, which indicate reduced efficiency or substation faults. Modeling return temperature is therefore critical but challenging due...

Weyl-Transition-Driven Giant Reversible Orbital Hall Conductivity

Abstract The orbital Hall conductivity (OHC) is central to orbitronics, yet its microscopic control remains largely unexplored. Here we identify a general mechanism in which tilted Weyl crossings formed by orbitally distinct bands generate a strongly asymmetric orbital Berry curv...

digitaldesignunit/csc: CSC 0.5.1.0

Pre-work for the 0.6 data model: runtime, releases and deployment, client identification, privacy, and a local test environment. No data-model change. From this release on, backend, web frontend and Grasshopper interface share one version and are released together as tag v , buil...

Beta diversity of Arctiinae moths (Lepidoptera: Erebidae) along a recovering tropical forest gradient

Amid widespread biodiversity loss and alarming rates of tropical deforestation, the potential of secondary forest succession in restoring β-diversity is still widely unexplored. To investigate β-diversity along naturally recovering forests, we collected the functionally diverse g...

On a trust metric for stochastic multi-objective model-based damage localisation

Model-based structural health monitoring (SHM) is commonly applied to identify the position and extent of potential damage. This is achieved by updating damage parameters to match measured dynamic responses, such as modal properties. Local reductions in stiffness in the updated m...

Inkjet Printing of MXene Gas Sensors for Agricultural Monitoring

Abstract Inkjet printing enables scalable fabrication of nanomaterial-based devices, but stable droplet formation and reproducible deposition remain challenging for emerging nanosheet inks. In this work, we develop a model-guided inkjet printing framework that monitors and optimi...

Precise Nanoscale Mapping of Electric Fields Across Random Grain Boundaries in Polycrystalline Oxides Using Precession‐Assisted 4D‐STEM

ABSTRACT Space charge layers (SCLs) at grain boundaries play a crucial role in modulating electric fields and thereby influence functional properties of materials. However, experimental analysis of these localized electric fields and the corresponding charge distribution remains...
