Generative KI für TA
Many scientists use generative AI in their scientific work. People working in technology assessment (TA) are no exception. TA's approach to generative AI is twofold: on the one hand, generative AI is used for TA work, and on the other hand, generative AI is the subject of TA research. After briefly outlining the phenomenon of generative AI and formulating requirements for its use in TA, the following article discusses in detail the structural causes of the problems associated with it. Although …

Non-local random deposition models for earthquakes and energy propagation
We investigate a new class of non-local random deposition models, initially introduced by physicists to study the field of mechanical constraints (stress) applied along a line or on a given area located in a seismic zone. The non-local features are twofold. First, the falling objects have random and heavy-tailed dimensions. Second, the locations where the objects are falling are at least for some of the models that we consider, depending on the shape of the surface before deposition. We conside…

GENMANIP: LLM-driven Simulation for Generalizable Instruction-Following Manipulation
Robotic manipulation in real-world settings remains challenging, especially regarding robust generalization. Existing simulation platforms lack sufficient support for exploring how policies adapt to varied instructions and scenarios. Thus, they lag behind the growing interest in instruction-following foundation models like LLMs, whose adaptability is crucial yet remains underexplored in fair comparisons. To bridge this gap, we introduce GenManip, a realistic tabletop simulation platform tailore…

Higher-order Stirling cycle and subset triangles: Total positivity, continued fractions and real-rootedness
Given a lower-triangular matrix of real numbers, one can ask the following four total-positivity questions: total positivity of the triangle itself; total positivity of its row-reversal; Toeplitz-total positivity of its row sequences (equivalent to negative-real-rootedness of the row-generating polynomials); and coefficientwise Hankel-total positivity of the sequence of row-generating polynomials. In this paper, we introduce two infinite families of lower-triangular matrices generalising the St…

Forgotten treasures in the HST/FOC UV imaging polarimetric archives of active galactic nuclei -- IV. 5 Orphaned AGNs
The Faint Object Camera (FOC) onboard the Hubble Space Telescope (HST) acquired high-resolution, spatially resolved polarimetric images of nearby Active Galactic Nuclei (AGNs) in the near ultraviolet (near-UV) band. Among the 25 individual targets in the polarized archives, 8 had no published analysis until the beginning of this series of papers. We tackle the last 5 targets in the following. In this paper, we finalize the publication of near-UV imaging polarimetry of AGNs in the HST/FOC archiv…

ODYSSEY: Open-World Quadrupeds Exploration and Manipulation for Long-Horizon Tasks
Language-guided long-horizon mobile manipulation has long been a grand challenge in embodied semantic reasoning, generalizable manipulation, and adaptive locomotion. Three fundamental limitations hinder progress: First, although large language models have improved spatial reasoning and task planning through semantic priors, existing implementations remain confined to tabletop scenarios, failing to address the constrained perception and limited actuation ranges of mobile platforms. Second, curre…
