MRI method maps blood flows in reverse for deeper insight into brain physiology
The venous system maintains the health of our brains by removing deoxygenated blood and other waste products, but its complexity and variability have made scientific study difficult. Now, a UC Berkeley-led team of researchers has developed an innovative MRI technique that may expand our understanding of this critical system.

Volle Fahrt voraus im Rückwärtsgang! [Full speed ahead in reverse gear!] What this TV report opens with seems to be a new motto for the German automotive industry. This week, a German manufacturer set a new world record for reversing in an electric truck. The German automotive industry as a whole is also attempting to reverse in electric mode: it has presented a 10-point plan to postpone, water down, weaken, undermine, regret, delay, reduce, replace, backtrack on and ridicule European CO2 re…

Please, tell me again how anarchism is chaos.
If this whole sorry episode of human history shows us one thing, it’s not that “we don’t need leaders” but that the very concept of “leaders” is incompatible with the future of our species. Advanced civilisation cannot survive under these primitive hierarchies that concentrate inordinate amounts of power in the hands of a relative handful of individuals. Look at the sorry state of these danger clowns.
Either we find ways to devolve po…

Understanding and Meeting Practitioner Needs When Measuring Representational Harms Caused by LLM-Based Systems
The NLP research community has made publicly available numerous instruments for measuring representational harms caused by large language model (LLM)-based systems. These instruments have taken the form of datasets, metrics, tools, and more. In this paper, we examine the extent to which such instruments meet the needs of practitioners tasked with evaluating LLM-based systems. Via semi-structured interviews with 12 such practitioners, we find that practitioners are often unable to use publicly a…

On the domination of surface-group representations in $\mathrm{PU}(2,1)$
This article explores surface-group representations into the complex hyperbolic group $\mathrm{PU}(2,1)$ and presents domination results for a special class of representations called $T$-bent representations. Let $S_{g,k}$ be a punctured surface of negative Euler characteristic. We prove that for a $T$-bent representation $ρ: π_1(S_{g,k}) \rightarrow \mathrm{PU}(2,1)$, there exists a discrete and faithful representation $ρ_0: π_1(S_{g,k}) \rightarrow \mathrm{PO}(2,1)$ that dominates $ρ$ in…

wikiconflict: Wikipedia edit wars (2009)
A network representing editorial interactions among editors of the English Wikipedia. Nodes are editors, and an edge denotes an edit conflict between the two editors. Edge are timestamped and signed. A positive sign indicates the users have agreement on the edit, and the negative sign indicates a disagreement (a reversion) on the edit.
This network has 118100 nodes and 2917785 edges.
