Towards Sharp Minimax Risk Bounds for Operator Learning

arXiv:2512.17805v1 Announce Type: cross
Abstract: We develop a minimax theory for operator learning, where the goal is to estimate an unknown operator between separable Hilbert spaces from finitely many noisy input-output samples. For uniformly bounded Lipschitz operators, we prove information-theo…

Four special Poncelet triangle families about the incircle

arXiv:2512.17440v1 Announce Type: cross
Abstract: We describe four special families of ellipse-inscribed Poncelet triangles about the incircle which maintain certain triangle centers stationary and which also display interesting conservations.

Comparing the Fairness of Recursively Balanced Picking Sequences

arXiv:2512.17604v1 Announce Type: new
Abstract: Picking sequences are well-established methods for allocating indivisible goods. Among the various picking sequences, recursively balanced picking sequences -- whereby each agent picks one good in every round -- are notable for guaranteeing allocation…

ALMA observations reveal multiscale fragmentation in massive star formation

Researchers from Yunnan University, the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences, and the National Astronomical Observatory of Japan have unveiled new insights into the fragmentation mechanisms of high-mass star-forming regions.

Non-Perturbative Trivializing Flows for Lattice Gauge Theories

arXiv:2410.13161v2 Announce Type: replace-cross
Abstract: Continuous normalizing flows are known to be highly expressive and flexible, which allows for easier incorporation of large symmetries and makes them a powerful computational tool for lattice field theories. Building on previous work, we pre…

Study: More eyes on the skies will help planes reduce climate-warming contrails

Images from geostationary satellites alone aren’t enough to help planes avoid contrail-prone regions, MIT researchers report.

DeContext as Defense: Safe Image Editing in Diffusion Transformers

arXiv:2512.16625v2 Announce Type: replace
Abstract: In-context diffusion models allow users to modify images with remarkable ease and realism. However, the same power raises serious privacy concerns: personal images can be easily manipulated for identity impersonation, misinformation, or other mali…

Sedna: Sharding transactions in multiple concurrent proposer blockchains

arXiv:2512.17045v1 Announce Type: new
Abstract: Modern blockchains increasingly adopt multi-proposer (MCP) consensus to remove single-leader bottlenecks and improve censorship resistance. However, MCP alone does not resolve how users should disseminate transactions to proposers. Today, users either…

Set-theoretic solution for the tuning problem

arXiv:2506.13969v2 Announce Type: replace
Abstract: In this paper I want to suggest a new solution to the problem of musical tuning. On one hand, I see it as a generalization of Just Intonation (JI) to inharmonic timbers, on another, as a unification of spectral interference and harmonicity contrib…

Resource-efficient medical image classification for edge devices

arXiv:2512.17515v1 Announce Type: cross
Abstract: Medical image classification is a critical task in healthcare, enabling accurate and timely diagnosis. However, deploying deep learning models on resource-constrained edge devices presents significant challenges due to computational and memory limit…

Rex: Proposed Safe Rust Kernel Extensions For The Linux Kernel, In Place Of eBPF

University researchers presented Rex at this month's Linux Plumbers Conference 2025 in Tokyo. Rex is designed for "safe and usable" Rust-based kernel extensions that could serve in place of eBPF programs for extending the Linux kernel functionality...

Stardust study resets how life's atoms spread through space

Starlight and stardust are not enough to drive the powerful winds of giant stars, transporting the building blocks of life through our galaxy. That's the conclusion of a new study from Chalmers University of Technology, Sweden, of red giant star R Doradus. The result overturns a long-held idea about…

A First Look at the Self-Admitted Technical Debt in Test Code: Taxonomy and Detection

arXiv:2510.22409v2 Announce Type: replace
Abstract: Self-admitted technical debt (SATD) refers to comments in which developers explicitly acknowledge code issues, workarounds, or suboptimal solutions. SATD is known to significantly increase software maintenance effort. While extensive research has …

Relative Error Fair Clustering in the Weak-Strong Oracle Model

arXiv:2506.12287v2 Announce Type: replace
Abstract: We study fair clustering problems in a setting where distance information is obtained from two sources: a strong oracle providing exact distances, but at a high cost, and a weak oracle providing potentially inaccurate distance estimates at a low c…

Study shows the 2008 recession caused people to identify with a lower class

Class identity, which is how individuals view their economic and social positions in relation to others, has wide-ranging effects on people's well-being, thoughts, and behavior. Previous studies have shown that people who identify with a higher class have better physical and emotional health, tend t…

How spatial scale shapes plant invasions

Scientists reveal that the scale of analysis determines whether invasive plants succeed by resembling or differing from native species, resolving decades of conflicting ecological evidence.

Some mammals can hit pause on a pregnancy—understanding how that happens could help us treat cancer

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the uterine wall—pausing pregnancy until she senses that her fat reserves are aligned with the season. This strategy, known as embryonic diapause, is practiced by hundreds of mammals,…

SDUM: A Scalable Deep Unrolled Model for Universal MRI Reconstruction

arXiv:2512.17137v1 Announce Type: new
Abstract: Clinical MRI encompasses diverse imaging protocols--spanning anatomical targets (cardiac, brain, knee), contrasts (T1, T2, mapping), sampling patterns (Cartesian, radial, spiral, kt-space), and acceleration factors--yet current deep learning reconstru…
