Scale-invariant dynamics in a purely deterministic Game of Life model
Scale invariance is a key feature that characterizes criticality in complex dynamical systems, which often organize into structures exhibiting no typical size and/or lifespan. While random external inputs or tunable stochastic interactions are typically required for showcasing such criticality, the question of whether scale-invariant dynamics can emerge from purely deterministic interactions remains unclear. In this work, we discover highly affirmative signatures of critical dynamics in equal-s…

"Here is the thing: the video describes, at an excruciatingly slow pace (at least by the standards of our generation’s TikTok-formatted brains), with the terms and phraseology of 1968, and during no less than one and a half hours, the very computer you are using to read this article. Yes, the one on your lap or on your desk."

As in any human group, there are certain pilgrimages, certain rites of passage that all software developers apparently must go through. They are various and equally anecdotical: to compile and boot their own Linux kernel; to read "The Art of Computer Programming" in its entirety (and then send their CV to Bill Gates); to give a presentation in a conference; and finally, to sit through the whole duration of "The Mother of All Demos", the recording of the unavoidable presentation made by Douglas …

ART-DECO: Arbitrary Text Guidance for 3D Detailizer Construction
We introduce a 3D detailizer, a neural model which can instantaneously (in <1s) transform a coarse 3D shape proxy into a high-quality asset with detailed geometry and texture as guided by an input text prompt. Our model is trained using the text prompt, which defines the shape class and characterizes the appearance and fine-grained style of the generated details. The coarse 3D proxy, which can be easily varied and adjusted (e.g., via user editing), provides structure control over the final shap…

Last week I watched a new apprentice take 15 minutes to type a simple email – using the eagle-search system, eyes glued to the keyboard.
Over 12 years of #school education behind them, able to analyze Shakespeare and solve math problems, but typing as if they're seeing a computer for the first time!
HOW is it possible that in 2025 we are still producing graduates who can…

Decomposing a factorial into large factors
Let $t(N)$ denote the largest number such that $N!$ can be expressed as the product of $N$ integers greater than or equal to $t(N)$. The bound $t(N)/N = 1/e-o(1)$ was apparently established in unpublished work of Erdős, Selfridge, and Straus; but the proof is lost. Here we obtain the more precise asymptotic $$ \frac{t(N)}{N} = \frac{1}{e} - \frac{c_0}{\log N} + O\left( \frac{1}{\log^{1+c} N} \right)$$ for an explicit constant $c_0 = 0.30441901\dots$ and some absolute constant $c>0$, answering …

A limit on the mass of the Taurid Resonant Swarm at sub-100 meter sizes
We report on a pencil-beam survey of the Taurid Swarm, a possible concentration of bodies in the Taurid meteoroid stream associated with the 7:2 mean-motion resonance with Jupiter. Canada-France-Hawaii Telescope MegaCam observations reaching apparent magnitudes of 24.5 in the gri filter were taken over three nights. Rates of motion on the sky allowed for the quick elimination of main-belt objects from the over 1000 moving sources seen. Eight candidates with on-sky rates of motion consistent wit…

A bit baffled by my colleagues' and students' helplessness regarding "new" digital tools - considering that my grandpa, who is turning 97 in a week and is almost blind, is reading a lot of online news and tutorials ("TV is boring"), still sends e-cards for all our birthdays, recalculates all his care bills with a huge Excel table, and apparently has a LinkedIn account (he hasn't worked since 1990) 🤷‍♀️

Multiple Object Tracking in Video SAR: A Benchmark and Tracking Baseline
In the context of multi-object tracking using video synthetic aperture radar (Video SAR), Doppler shifts induced by target motion result in artifacts that are easily mistaken for shadows caused by static occlusions. Moreover, appearance changes of the target caused by Doppler mismatch may lead to association failures and disrupt trajectory continuity. A major limitation in this field is the lack of public benchmark datasets for standardized algorithm evaluation. To address the above challenges,…

11 can be reduced to 10
Laffey and Smigoc proved that for every 2x2 doubly nonnegative integer matrix A, icpr(A) is less than or equal to 11. We prove that 11 can be replaced by 10, and show that for many small matrices, even by 9.15
