Heute bin ich mir sozusagen selber aufs Dach gestiegen: der letzte Sturm hatte einen Dachziegel ausgehebelt, der Ziegel ist dann einen halben Meter das Dach runter gerutscht und auf den anderen Ziegeln liegen geblieben. Jetzt ist der Dachziegel wieder an Ort und Stelle. Never take broken for an answer. #diy

freshmen: Zeggelink's freshmen (1999)
Snapshots of friendships among freshmen majoring in Sociology at the University of Groningen, collected five times over the 1998-1999 year. The direction of an edge indicates that student i is friends with student j, and the edge weight gives their friendship level from 1 (best friend) to 5 (troubled relation). Metadata include gender, age, program type, and smoking behavior.
This network has 34 nodes and 1156 edges.

Mit der Hafenfähre kommt Ihr in Hamburg an der Seemannsmission Altona vorbei.
Das ist ein Hotel für Seeleute (auch andere Gäste können dort buchen).
Sie werden dort beim Besatzungswechsel untergebracht oder auch mal, wenn sie krank sind für längere Zeit.
Das Team weiß, was für Seeleute wichtig ist.
Übrigens: die Hafenfähre ist im HVV oder Deutschlandticket dabei

TUC-PPO: Team Utility-Constrained Proximal Policy Optimization for Spatial Public Goods Games
We introduce Team Utility-Constrained Proximal Policy Optimization (TUC-PPO), a new deep reinforcement learning framework. It extends Proximal Policy Optimization (PPO) by integrating team welfare objectives specifically for spatial public goods games. Unlike conventional approaches where cooperation emerges indirectly from individual rewards, TUC-PPO instead optimizes a bi-level objective integrating policy gradients and team utility constraints. Consequently, all policy updates explicitly inc…

Magnetic control of metafluids for fluid-like applications of metamaterials
Metamaterials are structures composed of repeating unit-cells which enable macro-scale properties not found in nature. Since metamaterials are typically solid structures with predetermined interconnections, it is challenging to leverage their unique properties for many critical applications that require fluid-like behavior, such as heat engines or cooling cycles. Recent research suggested overcoming this limitation by creating a mechanical metafluid', which is a lubricated suspension of multist…
