Fine-grained Timing Analysis of Digital Integrated Circuits in Answer Set Programming
In the design of integrated circuits, one critical metric is the maximum delay introduced by combinational modules within the circuit. This delay is crucial because it represents the time required to perform a computation: in an Arithmetic-Logic Unit it represents the maximum time taken by the circuit to perform an arithmetic operation. When such a circuit is part of a larger, synchronous system, like a CPU, the maximum delay directly impacts the maximum clock frequency of the entire system. Ty…

Citizen science illuminates the nature of city lights: #LightPollution

Yesterday Trump told us that his plan was to remove 21m people from the United States,
or 6% of our current population and at least 5% of our total current workforce.
“All of them have to go home.”
A few points about this insane post:
Best estimates are that the total undocumented population in the US is between 12m and 15m.
The figure that Trump and his regime keeps using
- 21m came in under Biden
- is made up and false.
Here’s the latest Pe…

Russland spricht von Angriffen auf militärische Ziele
Nach Darstellung des russischen Verteidigungsministeriums wurden bei den jüngsten Angriffen auf die Ukraine militärische Ziele attackiert. Die Angriffe hätten auf "Unternehmen des ukrainischen militärisch-industriellen Komplexes" in Lwiw, Charkiw und Lutsk abgezielt sowie auf einen Militärflugplatz. Das Ziel der Angriffe sei erreicht worden.

Diagnosing Failures in Large Language Models' Answers: Integrating Error Attribution into Evaluation Framework
With the widespread application of Large Language Models (LLMs) in various tasks, the mainstream LLM platforms generate massive user-model interactions daily. In order to efficiently analyze the performance of models and diagnose failures in their answers, it is essential to develop an automated framework to systematically categorize and attribute errors. However, existing evaluation models lack error attribution capability. In this work, we establish a comprehensive Misattribution Framework wi…

RAG has revolutionised AI by merging search and generation. Agentic behaviour takes this search to the next level by enabling LLMs to make decisions and call tools. At this year's Berlin Buzzwords, Bilge Yücel will discuss how agentic behaviour enhances pipelines, what it means for a system to act as an 'agent', and core concepts such as routing, tool calling and reasoning, along with a live demo.

On the Birkhoff conjecture for Kepler billiards
We investigate the integrability of Kepler billiards-mechanical billiard systems in which a particle moves under the influence of a Keplerian potential and reflects elastically at the boundary of a strictly convex planar domain. Our main result establishes that, except possibly for one location of the gravitational center, analytic integrability at high energies occurs only when the domain is an ellipse and the center is placed at one of its foci. This provides a partial affirmative answer to a…
