Mathematical models reveal a 'hidden order' in dryland vegetation worldwide
If you've ever traveled through drylands, you may have noticed striking vegetation patterns—stripes, spots, or rings—scattered across otherwise barren landscapes. From "tiger bush" in West Africa to the enigmatic "fairy circles" of Namibia, these patterns have long inspired wonder and scientific curiosity.

Putnam-like dataset summary: LLMs as mathematical competition contestants
In this paper we summarize the results of the Putnam-like benchmark published by Google DeepMind. This dataset consists of 96 original problems in the spirit of the Putnam Competition and 576 solutions of LLMs. We analyse the performance of models on this set of problems to verify their ability to solve problems from mathematical contests.

Roadmap to planar electron-ion point Paul trap
We present a technical guide to developing a quantum-mechanical system with co-trapped laser-cooled ions and electrons, aiming to utilize this mixed-species system in quantum computing and sensing. We outline a method to control the system's quantum state and provide a blueprint for a forward-compatible design for containing it. The proposed technical solution features a planar configuration with a large trapping volume located at a considerable height above the electrode plane. We detail a man…

GSM8K-V: Can Vision Language Models Solve Grade School Math Word Problems in Visual Contexts
Vision language models (VLMs) achieve unified modeling of images and text, enabling them to accomplish complex real-world tasks through perception, planning, and reasoning. Among these tasks, reasoning is particularly representative, with mathematical reasoning serving as a prominent example. It highlights the high-level capability of VLMs to comprehend mathematical information in images and to perform sophisticated reasoning. Recently, numerous visual mathematical reasoning benchmarks have bee…

Comment des partenaires de Pierre-Edouard Stérin mettent le milliardaire à distance : « Il est devenu radioactif »
Les engagements politiques à l’extrême droite de l’entrepreneur et de son numéro deux, François Durvye, conseiller du Rassemblement national, commencent à ternir l’image du groupe, en proie à des difficultés financières.

Gorenstein-Projective Modules over the Ring of Dual Integers
The ring of dual integers is the bounded polynomial ring $\mathbb Z[ε]=\mathbb Z[T]/(T^2)$ with integer coefficients. We describe the (finitely generated) Gorenstein-projective $\mathbb Z[ε]$-modules as the torsionless $\mathbb Z[ε]$-modules, or equivalently, as the perfect differential structures of abelian groups. Moreover, the stable category of G-proj$\mathbb Z[ε]$ modulo projectives is shown to be equivalent to the orbit category $\mathcal D^b(\mathbb Z)/[1]$ of the derived category of…
