Collective communication in a transparent world: Phase transitions in a many-body Potts model and social-quantum duality
We consider the Schelling-like social competition reflected in "dynamics of opinions" among groups of agents ("communities") in a highly transparent world. Specifically, we investigate a $q$-state Potts spin system with competing two- and three-body interactions on a complete graph. Agents interact through pairwise repulsion (opposing opinions) between different communities and three-body attraction (shared opinions) within the same community. In the thermodynamic limit, we identify variants of…

We all perform tasks in our day-to-day work that are considered 'non-promotable' – these are crucial for project success, but they won't get you promoted. This is commonly known as 'glue work', a term coined by Tanya Reilly. At Berlin Buzzwords 2025, Fatima Taj shared her personal experience of narrowly avoiding the trap of being permanently stuck with glue work and explained how to handle similar situations.

Es ist still geworden um das Geschehen in der Manege. Geschuldet ist dies vermutlich aufgrund der Übermüdung aller Akrobat:innen. Viele haben ihr Repertoire an Kunststücken auch schon ausgeschöpft und die Manege verlassen. Die Älteren sind wie gewohnt widerstandsfähiger und schöpfen aus ihrer Erfahrung. Hier wird es wohl noch etwas dauern. #dem25 ^mr

Channel 4 Says It Doesn’t Use NDAs, But Documents Reveal Company Is Curbing Free Speech Of Aggrieved Ex-Employees
Channel 4 described itself as the "defender of free speech," but documents reveal it is restricting what former staffers can say about the company.

A nonstandard finite difference scheme for an SEIQR epidemiological PDE mode
This paper introduces a nonstandard finite difference (NSFD) approach to a reaction-diffusion SEIQR epidemiological model, which captures the spatiotemporal dynamics of infectious disease transmission. Formulated as a system of semilinear parabolic partial differential equations (PDEs), the model extends classical compartmental models by incorporating spatial diffusion to account for population movement and spatial heterogeneity. The proposed NSFD discretization is designed to preserve the cont…

Production, Quality Assurance and Quality Control of the SiPM Tiles for the DarkSide-20k Time Projection Chamber
The DarkSide-20k dark matter direct detection experiment will employ a 21 m^2 silicon photomultiplier (SiPM) array, instrumenting a dual-phase 50 tonnes liquid argon Time Projection Chamber (TPC). SiPMs are arranged into modular photosensors called Tiles, each integrating 24 SiPMs onto a printed circuit board (PCB) that provides signal amplification, power distribution, and a single-ended output for simplified readout. 16 Tiles are further grouped into Photo-Detector Units (PDUs).
