Discrete scalar curvature as a weighted sum of Ollivier-Ricci curvatures
We study the relationship between discrete analogues of Ricci and scalar curvature that are defined for point clouds and graphs. In the discrete setting, Ricci curvature is replaced by Ollivier-Ricci curvature. Scalar curvature can be computed as the trace of Ricci curvature for a Riemannian manifold; this motivates a new definition of a scalar version of Ollivier-Ricci curvature. We show that our definition converges to scalar curvature for nearest neighbor graphs obtained by sampling from a m…

är det inte intressant att så ofta när man gräver i kommentarsfältherrar som postar simpla talepunkter från högern hittar man antisemitiska konspirationsteorier

Correlative Analysis of Iron-Driven Structural, Optical, and Magnetic Properties in Natural Biotite Crystals
Biotite crystals are phyllosilicate trioctahedral micas with the general chemical formula K(Mg,Fe)3AlSi3O10(OH)2 that form a solid-solution series with iron-poor phlogopite and iron-rich annite endmembers. With a wide band gap energy and a layered structure with free surface charges, biotite nanosheets can be readily obtained by cleavage methods and used as dielectrics in nanodevice fabrication for the next generation of electronics and energy harvesting. Here, a comprehensive study of biotite …

EKHN: Oliver Albrecht, Propst für Rhein-Main, erfüllt sich einen lang gehegten Wunsch: Er will in seinen letzten Berufsjahren als Gemeindepfarrer arbeiten. Albrecht wird ab März 2026 Pfarrer in den Gemeinden Delkenheim und Wallau im Südosten des Dekanats Wiesbaden. „Vielleicht keine alltägliche Entscheidung, für mich aber ein ganz natürlicher Weg: Mein Herz schlug schon immer für die Gemeinde vor Ort“, sagt Albrecht. Er stellt sich bei der Herbstsynode Ende November nicht mehr zur Wiederwahl…

Post Traumatic Disorder
Adam O’Neal says he’s bringing “intellectual diversity” to The Washington Post’s opinion pages—but the moves he’s making behind the scenes tell a different story.

Hallucination reduction with CASAL: Contrastive Activation Steering For Amortized Learning
Large Language Models (LLMs) exhibit impressive capabilities but often hallucinate, confidently providing incorrect answers instead of admitting ignorance. Prior work has shown that models encode linear representations of their own knowledge and that activation steering can reduce hallucinations. These approaches, however, require real-time monitoring and intervention during inference. We introduce Contrastive Activation Steering for Amortized Learning (CASAL), an efficient algorithm that conne…
