The model fitting of Gaia DR3 Classical Cepheid light and radial velocity curves
Classical Cepheids are key astrophysical laboratories for studying stellar structure and evolution, and for calibrating the cosmic distance scale. Despite major progress, uncertainties remain regarding their masses, luminosities, distances, and the role of processes like core overshooting, rotation, and mass loss. The high-precision data from ESA Gaia's third data release offer an opportunity to address these issues. This study aims to estimate the structural parameters and distances of a sampl…

Wieviel Metafiktion/Noveau Roman/Postmoderne steckt in deinen Büchern?
Musste ich erstmal nachschlagen und finde die Antwort gar nicht so eindeutig 🤔.
Die Märchen enthalten Metafiktion-Elemente, weil ich ihnen jeweils den Kommentar einer Märchensammlerin nachstelle, die das Gelesene literaturhistorisch einordnet. Das erlaubt mir auch Freihei…

Actively induced supercoiling can slow down plasmid solutions by trapping the threading entanglements
Harnessing the topology of ring polymers as a design motif in functional nanomaterials is becoming a promising direction in the field of soft matter. For example, the ring topology of DNA plasmids prevents the relaxation of excess twist introduced to the polymer, instead resulting in helical supercoiled structures. In equilibrium semi-dilute solutions, tightly supercoiled rings relax faster than their torsionally relaxed counterparts, since the looser conformations of the latter allow for rings…

Ultra-High-Temperature Vacuum Prober for Electrical and Thermal Measurements
We develop an ultra-high-temperature vacuum probe station (UHT-VPS) featuring a sample holder heated by thermal radiation from a silicon carbide heater. This contactless configuration electrically isolates the sample from the high-power heating source through a vacuum gap, ensuring reliable measurements under extreme conditions. The capability of this UHT-VPS to measure electrical signals from 30 nV upward on bulk sapphire is demonstrated using the 3w/2w method. Measurements are continuously op…

Multilingual Political Views of Large Language Models: Identification and Steering
Large language models (LLMs) are increasingly used in everyday tools and applications, raising concerns about their potential influence on political views. While prior research has shown that LLMs often exhibit measurable political biases--frequently skewing toward liberal or progressive positions--key gaps remain. Most existing studies evaluate only a narrow set of models and languages, leaving open questions about the generalizability of political biases across architectures, scales, and mult…

Pressure and doping effects on the electronic structure and magnetism of the single-layer nickelate La$_2$NiO$_4$
La$_2$NiO$_4$ is a prototypical member of the Ruddlesden-Popper nickelate series that offers a valuable reference point for elucidating the key ingredients behind the intriguing properties of these systems. However, the structural and electronic properties of La$_2$NiO$_4$ under pressure and doping remain surprisingly underexplored. Here, we investigate these properties using density-functional-theory calculations. We find that its tetragonal $I4/mmm$ structure can be stabilized, not only under…

Efficient Neuro-Symbolic Learning of Constraints and Objective
In the ongoing quest for hybridizing discrete reasoning with neural nets, there is an increasing interest in neural architectures that can learn how to solve discrete reasoning or optimization problems from natural inputs, a task that Large Language Models seem to struggle with. Objectives: We introduce a differentiable neuro-symbolic architecture and a loss function dedicated to learning how to solve NP-hard reasoning problems. Methods: Our new probabilistic loss allows for learning both t…
