Complexity reduction of physical models: an equation-free approach by means of scaling
The description of complex physical phenomena often involves sophisticated models that rely on a large number of parameters, with many dimensions and scales. One practical way to simplify that kind of models is to discard some of the parameters, or terms of underlying equations, thus giving rise to reduced models. Here, we propose a general approach to obtaining such reduced models. The method is independent of the model in use, i.e., equation-free, depends only on the interplay between the sca…

Experten zweifeln Sicherheit von Musks neuem XChat an - t3n – digital pioneers
Mit XChat verspricht Elon Musk verschlüsselte Kommunikation auf seinem sozialen Netzwerk X. Doch Expert:innen äußern ernsthafte Bedenken an der Sicherheit der neuen Nachrichtenfunktion. Elon Musk hat mit XChat eine neue Version der Nachrichtenfunktion der Social-Media-Plattform X angekündigt. Über das neue Feature soll auch das Versenden von Dateien möglich sein. Wie The Register berichtet, zeigen sich […]

Another look at qualitative properties of eigenvalues using effective Hamiltonians
The goal of this paper is to review several qualitative properties of well-known eigenvalue problems using a different perspective based on the theory of effective Hamiltonians, working exclusively on the Hopf-Cole transform of the equation. We revisit some monotonicity results as well as the derivation of several scaling limits by means of the Donsker-Varadhan formula, and we point out several differences between the case of quadratic Hamiltonians and non-quadratic ones.

MERIT: Multilingual Semantic Retrieval with Interleaved Multi-Condition Query
Semantic retrieval is crucial for modern applications yet remains underexplored in current research. Existing datasets are limited to single languages, single images, or singular retrieval conditions, often failing to fully exploit the expressive capacity of visual information as evidenced by maintained performance when images are replaced with captions. However, practical retrieval scenarios frequently involve interleaved multi-condition queries with multiple images. Hence, this paper introduc…

Graph neural network model for the era of large atomistic models
Foundation models, or large atomistic models (LAMs), aim to universally represent the ground-state potential energy surface (PES) of atomistic systems as defined by density functional theory (DFT). The scaling law is pivotal in the development of large models, suggesting that their generalizability in downstream tasks consistently improves with increased model size, expanded training datasets, and larger computational budgets. In this study, we present DPA3, a multi-layer graph neural network f…

“La Friche”, coécrit avec Marc Mahé Petska
J’ai toujours rêvé d’écrire quatre mains (sans superpouvoir ni mutation), et la rencontre avec Marc, d’abord ses poèmes sur Twitter, puis tout particulièrement de Cyberpunk is dead, baby ne pouvait que réactiver cette envie. La nouvelle La Friche en est issue – après une longue gestation (six ans, autant dire que ça remonte Š une autre vie), mais un travail moins long qu’un peu trop ambitieux au départ et surtout intermittent,…

A Be star-black hole binary with a wide orbit from LAMOST time-domain survey
Binary systems consisting of an early type star and a black hole (BH) are crucial for understanding various astrophysical phenomena, particularly the origins of detected gravitational wave sources. Be binary systems are expected to represent a key evolutionary stage in hosting BHs. However, while hundreds of Be X-ray binaries are known, the only confirmed BH candidate in a Be binary remains highly controversial. We report the discovery of ALS 8814, a Be star-BH binary with a moderately eccentri…

Rotationally symmetric Ricci Flow on $\mathbb{R}^{n 1}$

Rotationally symmetric Ricci Flow on $\mathbb{R}^{n+1}$
We establish a short-time existence theory for complete Ricci flows under scaling-invariant curvature bounds, starting from rotationally symmetric metrics on $\mathbb{R}^{n+1}$ that are noncollapsed at infinity, without assuming bounded curvature. As a consequence, we construct a complete Ricci flow solution coming out of a rotationally symmetric metric, which has a cone-like singularity at the origin and no minimal hypersphere centered at the origin, using an approximation method.

Trump's sanctions on ICC prosecutor have halted tribunal's work
Nearly three months ago, U.S. President Donald Trump slapped sanctions on the International Criminal Court's chief prosecutor, Karim Khan. He has lost access to his email and his bank accounts have been frozen. American staffers at The Hague-based court also have been told that if they travel to the U.S. they risk arrest. In addition, some nongovernmental organizations have stopped working with the ICC. Rights groups say these problems will prevent victims of war crimes from getting justice.
