Tight Paths and Tight Pairs in Weighted Directed Graphs
We state the graph-theoretic computational problem of finding tight paths in a directed, edge-weighted graph, as well as its simplification of finding tight pairs. These problems are motivated by the need of algorithms that find so-called basic antecedents in closure spaces, in one specific approach to data analysis. We discuss and compare several algorithms to approach these problems.

Black hole photon ring beyond General Relativity: an integrable parametrization
In recent years, the shape of the photon ring in black holes images has been argued to provide a sharp test of the Kerr hypothesis for future black hole imaging missions. In this work, we confront this proposal to beyond Kerr geometries and investigate the degeneracy in the estimations of the black hole parameters using the circlipse shape proposed by Gralla and Lupsasca. To that end, we consider a model-independent parametrization of the deviations to the Kerr black hole geometry, dubbed Kerr …

The Freedom Flotilla „Madleen” is projected to arrive in just a few hours at a coast in Gaza. If anything happens to @… or the other activists, the international community will never forgive the current Israeli government for it.

Freiheit für Greta Thunberg, Yasemin Acar und alle Aktivist*innen der Freedom Flotilla - Online-Petition
Humanitäre Hilfe ist kein Verbrechen! Am 1. Juni 2025 wurde das zivile Hilfsschiff Madleen der Freedom Flotilla Coalition auf dem Weg nach Gaza in internationalen Gewässern gewaltsam von der israelischen Armee gestoppt, geentert und seine Besatzung verschleppt. An Bord befanden sich ausschließlich unbewaffnete Freiwillige und dringend für den Gazastreifen benötigte humanitäre Hilfsgüter wie Babynahrung, Medizin und Prothesen für verletzte Kinder. Unter den Festgehaltenen ist neben Greta…

Educators' Perceptions of Large Language Models as Tutors: Comparing Human and AI Tutors in a Blind Text-only Setting
The rapid development of Large Language Models (LLMs) opens up the possibility of using them as personal tutors. This has led to the development of several intelligent tutoring systems and learning assistants that use LLMs as back-ends with various degrees of engineering. In this study, we seek to compare human tutors with LLM tutors in terms of engagement, empathy, scaffolding, and conciseness. We ask human tutors to annotate and compare the performance of an LLM tutor with that of a human tut…

"There's one way to end this war. You say to Vladimir Putin:
If you don't stop this war, and we agree to the ceasefire terms I dictate, we are bringing Ukraine into NATO within 30 days. Which part of that sentence don't you understand? Do you want to mess with me? Test me.
That's how you end this war."

Less is More: some Computational Principles based on Parcimony, and Limitations of Natural Intelligence
Natural intelligence (NI) consistently achieves more with less. Infants learn language, develop abstract concepts, and acquire sensorimotor skills from sparse data, all within tight neural and energy limits. In contrast, today's AI relies on virtually unlimited computational power, energy, and data to reach high performance. This paper argues that constraints in NI are paradoxically catalysts for efficiency, adaptability, and creativity. We first show how limited neural bandwidth promotes conci…

Low-Resource Domain Adaptation for Speech LLMs via Text-Only Fine-Tuning
Recent advances in automatic speech recognition (ASR) have combined speech encoders with large language models (LLMs) through projection, forming Speech LLMs with strong performance. However, adapting them to new domains remains challenging, especially in low-resource settings where paired speech-text data is scarce. We propose a text-only fine-tuning strategy for Speech LLMs using unpaired target-domain text without requiring additional audio. To preserve speech-text alignment, we introduce a …

Reviewriter: AI-Generated Instructions For Peer Review Writing
Large Language Models (LLMs) offer novel opportunities for educational applications that have the potential to transform traditional learning for students. Despite AI-enhanced applications having the potential to provide personalized learning experiences, more studies are needed on the design of generative AI systems and evidence for using them in real educational settings. In this paper, we design, implement and evaluate \texttt{Reviewriter}, a novel tool to provide students with AI-generated …
