Union-Intersection Union-Find for Decoding Depolarizing Errors in Topological Codes
In this paper, we introduce the Union-Intersection Union-Find (UIUF) algorithm for decoding depolarizing errors in topological codes, combining the strengths of iterative and standard Union-Find (UF) decoding. While iterative UF improves performance at moderate error rates, it lacks an error correction guarantee. To address this, we develop UIUF, which maintains the enhanced performance of iterative UF while ensuring error correction up to half the code distance. Through simulations under code …

Humans, Machine Learning, and Language Models in Union: A Cognitive Study on Table Unionability
Data discovery and table unionability in particular became key tasks in modern Data Science. However, the human perspective for these tasks is still under-explored. Thus, this research investigates the human behavior in determining table unionability within data discovery. We have designed an experimental survey and conducted a comprehensive analysis, in which we assess human decision-making for table unionability. We use the observations from the analysis to develop a machine learning framewor…

Arithmetic Circuits with Division
We study the computational complexity of the membership problem for arithmetic circuits over natural numbers with division. We consider different subsets of the operations {intersection,union,complement,+,x,/}, where / is the element-wise integer division (without remainder and without rounding). Results for the subsets without division have been studied before, in particular by McKenzie and Wagner and Yang. The division is expressive because it makes it possible to describe the set of factors …

Cross-Channel Unlabeled Sensing over a Union of Signal Subspaces
Cross-channel unlabeled sensing addresses the problem of recovering a multi-channel signal from measurements that were shuffled across channels. This work expands the cross-channel unlabeled sensing framework to signals that lie in a union of subspaces. The extension allows for handling more complex signal structures and broadens the framework to tasks like compressed sensing. These mismatches between samples and channels often arise in applications such as whole-brain calcium imaging of freely…

Homotopy types of Hom complexes of graph homomorphisms whose codomains are cycles
For simple graphs $G$ and $H$, the Hom complex $\mathrm{Hom}(G,H)$ is a polyhedral complex whose vertices are the graph homomorphisms $G\to H$ and whose edges connect the pairs of homomorphisms which differ in a single vertex of $G$. Hom complexes play an important role in an algebro-topological approach to the graph coloring problem. It is known that $\mathrm{Hom}(G,H)$ is homotopy equivalent to a disjoint union of points and circles when both $G$ and $H$ are cycles. We generalize this known r…

The overflow in the Katona Theorem
Let $n>2r>0$ be integers. We consider families $\mathcal{F}$ of subsets of an $n$-element set, in which the union of any two members has size at most $2r$. One of our results states that for $n\geq 6r$ the number of members of size exceeding $r$ in $\mathcal{F}$ is at most $\binom{n-2}{r-1}$. Another result shows that for $n>3.5r$ the number of sets of size at least $r$ is at most $\binom{n}{r}$. Both bounds are best possible and the latter sharpens the classical Katona Theorem. Similar results…

qa_user: User interactions on Q&A websites (2016)
Networks of interactions among users from four online Q&A sites: Stack Overflow, Math Overflow, Super User, and Ask Ubuntu. A directed edge (i,j) indicates a user i responded to user j's post. Edges are timestamped. For each Q&A site, four differently defined networks are provided, based on the definition of an edge: (i) a user answered a question, (ii) a user commented on a question, (iii) a user commented on an answer…

With dozens of new studios and rapidly evolving tech, generative AI video is more embedded in Hollywood movies and TV than we may realize.

Die Union fordert Krankenhäuser effizienter zu machen. Ich hätte da eine ungewöhnliche Idee: könnten sich Krankenhäuser darauf konzentrieren, eine möglichst effektive Gesundheits­versorgung sicher zu stellen,¹ statt Gewinne machen zu müssen,² könnte das ganz entgegen der neoliberalen Lehre effizienter sein.

Forscher mahnen Verteidigungsstrategie für Europa an
Vier deutsche Friedensforschungsinstitute plädieren angesichts der veränderten Sicherheitslage für mehr eigenständige Verteidigung in Europa. "Die Europäische Union muss Strategien entwickeln, um ihre Verteidigung auf lange Sicht unabhängig von den USA sicherzustellen", forderten die Wissenschaftler zur Vorstellung ihres Friedensgutachtens 2025 in Berlin.

ich bin unter meinem „Klarnamen“¹ öffentlich dagegen, daß die Union andere² verpflichten will, unter ihrem „Klarnamen“¹ zu agieren. Anonyme wie pseudonyme Kommunikation – nicht nur in privaten Chatgruppen sondern auch gegenüber einer nicht klar gestimmten „Öffentlichkeit“ – ist wichtig. Ein Namenszwang schützt überhaupt nicht gegen die ganze Scheiße, die im Netz passiert.
