stackoverflow: Stack Overflow favorites (2011)
A bipartite network of users and the posts they have favorited, from the online Q&A site Stack Overflow. An edge (i,j) connects a user i to a post j if that user "favorited" that post (a kind of a rating). Edges are timestamped.
This network has 641876 nodes and 1301942 edges.

Klöckner läßt aber auch nichts aus. Für sie gibt es in der Politik unterschiedliche Meinungen, aber keine Lügen. Diese Aussage ist politisch heftig brisant und gefährlich.
Gerichte unterscheiden klar zwischen Tatsachen­behauptung und Meinungs­äußerung, und das ist juristisch relevant. So kann ich mit einer Meinungsäußerung zwar durchaus Ärger wegen Beleidigung (§ 185 StGB) bekommen, für üble Nachrede (§ 186 StGB) oder Verleumdung (§ 187 StGB) muß es schon eine falsche Tatsachenbehauptu…

Ich wäre schwer für einen Reservierungsboykott. Das ist reine Geldmacherei. Und btw: so viele reservierte Plätze, wie um mich rum frei bleiben, da könnte man meinen, da werde stark geflunkert. #bahn

Flexible constraint satisfiability and a problem in semigroup theory
We examine some flexible notions of constraint satisfaction, observing some relationships between model theoretic notions of universal Horn class membership and robust satisfiability. We show the \texttt{NP}-completeness of $2$-robust monotone 1-in-3 3SAT in order to give very small examples of finite algebras with \texttt{NP}-hard variety membership problem. In particular we give a $3$-element algebra with this property, and solve a widely stated problem by showing that the $6$-element Brandt …

Generating Satisfiable Benchmark Instances for Stable Roommates Problems with Optimization
While the existence of a stable matching for the stable roommates problem possibly with incomplete preference lists (SRI) can be decided in polynomial time, SRI problems with some fairness criteria are intractable. Egalitarian SRI that tries to maximize the total satisfaction of agents if a stable matching exists, is such a hard variant of SRI. For experimental evaluations of methods to solve these hard variants of SRI, several well-known algorithms have been used to randomly generate benchmark…

Infinite graphs satisfying the Bakry-Emery curvature condition CD(0, n): The modified heat equation and applications to geometric analysis
Let G = (V, p, $μ$) be a (finite or infinite) weighted graph with bounded geometry. Assuming that G satisfies the classical curvaturedimension condition of Bakry-Emery CD(K, n) with K $\ge$ 0 (for the usual Laplacian), we prove that the doubling volume property holds. One of the key points is to establish the existence and uniqueness of solutions of a modified non linear heat equation which replaces the standard one usually used in the case of Riemannian manifolds. Li-Yau and Harnack estimates…

Affectionate displays boost relationship satisfaction across cultures despite varying social norms
Displays of affection, such as hugging, kissing and holding hands, can be good for your health. They can reduce stress, boost mood and improve quality of life. Being affectionate in both public and private is also linked to happier relationships. But how much do differences in how willing partners are to show affection influence relationship satisfaction?
