From Birdwatch to Community Notes, from Twitter to X: four years of community-based content moderation
Community Notes (formerly known as Birdwatch) is the first large-scale crowdsourced content moderation initiative that was launched by X (formerly known as Twitter) in January 2021. As the Community Notes model gains momentum across other social media platforms, there is a growing need to assess its underlying dynamics and effectiveness. This Resource paper provides (a) a systematic review of the literature on Community Notes, and (b) a major curated dataset and accompanying source code to supp…

Just listened to an interesting online talk (#Balloon Facility (https://www.tifr.res.in/bf/) - here are the slides about astronomical observations they do; see also https://arxiv.org/abs/2112.04877 for a 2021 review paper about this work and the mentioned papers https://www.aanda.org/articles/aa/full_html/2013/08/aa21614-13/aa21614-13.html ("Large-scale mapping of the massive star-forming region RCW38 in the [CII] and PAH emission") and https://www.aanda.org/articles/aa/full_html/2021/07/aa35739-19/aa35739-19.html ("[CII] emission properties of the massive star-forming region RCW 36 in a filamentary molecular cloud").

The moduli spaces of left-invariant statistical structures on Lie groups
In the context of information geometry, the concept known as left-invariant statistical structure on Lie groups is defined by Furuhata--Inoguchi--Kobayashi [Inf. Geom. (2021)]. In this paper, we introduce the notion of the moduli space of left-invariant statistical structures on a Lie group. We study the moduli spaces for three particular Lie groups, each of which has a moduli space of left-invariant Riemannian metrics that is a singleton. As applications, we classify left-invariant conjugate s…

Majorization via positivity of Jack and Macdonald polynomial differences
Majorization inequalities have a long history, going back to Maclaurin and Newton. They were recently studied for several families of symmetric functions, including by Cuttler--Greene--Skandera (2011), Sra (2016), Khare--Tao (2021), McSwiggen--Novak (2022), and Chen--Sahi (2024+) among others. Here we extend the inequalities by these authors to Jack and Macdonald polynomials, and obtain conjectural characterizations of majorization and of weak majorization of the underlying partitions. We prove…

Banking alliance aimed at limiting fossil fuel investments collapses
A coalition formed to align the international banking sector’s investments with global climate goals has disbanded nearly four years after it was launched. Set up in 2021, the Net-Zero Banking Alliance (NZBA) was a U.N.-sponsored initiative to shift bank financing away from fossil fuels — the biggest source of climate changing greenhouse gases — and […]

Multi-spacecraft Measurements of the Evolving Geometry of the Solar Alfvén Surface Over Half a Solar Cycle
The geometry of a star's Alfvén surface determines stellar angular momentum loss, separates a causally distinct 'corona' and stellar wind, and potentially affects exoplanetary habitability. The solar Alfvén surface is the only such structure that is directly measurable and since 2021, has been routinely measured in situ by NASA's Parker Solar Probe (Parker). We use these unique measurements in concert with Solar Orbiter and L1 in situ data spanning the first half of the Solar Cycle 25 in time…
