Negative divisors can detect line-bundle instability on surfaces
A mathematical preprint gives exact detection rules for stable and semistable line bundles, while stopping short of classifying every destabilizer.
Quantum Model Links Yang-Lee Criticality to Damping Transition
Preprint: A formal construction maps selected open-system observables to Yang-Lee dynamics without post-selection, but it remains untested on quantum hardware.
Neutrino AI model maps hidden signals and ranks events by error
Preprint: The one-million-event PolarBERT analysis identified detector signals and tested an uncertainty head for ranking likely angular error, with calibration limits.
Quantum gravity proposal targets a massive ghost for confinement
Preprint: A formal construction makes ghost confinement conditional on bound states that the study does not show can form.
Constructive Framework Recasts Esakia Duality
Preprint: A formal point-free construction links Esakia frames with Heyting algebras and restricts Townsend’s localic Priestley duality without excluded middle or non-constructive choice.
AI system posts higher scores in varied geospatial tests
Preprint reports gains in Ebola nowcasting, Nigerian food-security downscaling and US health and disaster-risk benchmarks.
AI Finds Civil Plan Pages, But Rules Remain Hard
Preprint: PlanSightRAG performed strongly on visual retrieval and controlled compliance tests, while real-plan rule extraction remained unreliable.
Math Study Sets Sharp Smoothness Limit on Even-Dimensional Spheres
An arXiv preprint dated 26 August 2026 builds strictly positive definite examples that reach the guaranteed order, then fail at the next derivative.
AI method posts higher accuracy while learning new visual tasks
An arXiv preprint reports 62.5% average accuracy for a visual-dependence approach trained sequentially on answer-unlabeled image-question pairs across six multimodal tasks.
New AI dataset pairs fitness video with muscle signals and errors
Preprint: A 7,512-sample project combines exercise video, physiological signals and expert error labels, but the supplied text omits detailed performance figures.
TRAPPIST-1 Shows Solar-Like Chemistry, With a Carbon Twist
Preprint analysis finds near-solar elemental abundances and an elevated carbon isotope ratio in the star.
New framework turns torsion-balance noise into gravity-test limits
Preprint: A methods paper shows how calibrated spectra can bound known torque signals and extra stationary stochastic noise.
Model links Hall-viscosity gradient to unequal electronic vortices
Preprint modeling associates a spatial Hall-viscosity change with a stronger vortex in one chamber and a weaker or suppressed vortex in the other.
Dust maps suggest some hydrogen clouds lie beyond the Local Bubble
Preprint: A four-sightline analysis links some absorbing structures to the Local Bubble’s wall and places another more than 100 parsecs beyond it, with important uncertainties.
New six-million-pair dataset targets reference-based video editing
This preprint reports strong benchmark scores and 50% lower training computation, but the evidence comes largely from AI judges and small human studies.
Graphene Preprint Models Two Distinct Magnetic Domain-Wall Textures
The theoretical work examines whether spin and valley can unlock inside rhombohedral graphene walls and predicts a possible superconducting-junction voltage.
Free square contains infinitely many non-unitarily equivalent free extreme points
Preprint: A proof-based study extends the level-2 result to every bounded convex polygon with at least four sides.
Robot Policy Scores Higher on Unseen Tasks Using Video Prompts
Preprint: Zero-WAM averaged 46.95% success on seven unseen simulation tasks and posted higher rates than LingBot-VA in three real-world task families.
AI GUI prototype reports higher component counts in 19-person study
Preprint: Separate tests report stronger GUI ranking than BM25 and high self-rated usability for RaWi.
