Paper-Writing Trajectories Linked to Better AI Writing Scores
A preprint reports higher automated writing scores for models trained on generated multi-turn versions of scientific papers.
AI models agree on shape's feel, but not consistently
The Preprint reports that six vision-language models ranked grey 3D objects more similarly on affective word pairs than on unrelated pairs, while agreement varied by category and wording.
Adversarial rewrites expose a weak link in graph-based QA
Preprint: Answer-preserving rewrites often left the answer in the retrieved graph while the system still failed to reach it.
Quantum channels show lower output entropy when paired
Preprint: Finite-dimensional channels approach an infinite model and eventually show strict two-copy nonadditivity, although the reported construction is not practically executable.
Preprint gives new local formulas for a conjecture on Siegel forms
A preprint covers two valuation-one Fourier-Jacobi cases for Sp4 and links them to a global identity that remains unproved.
Circuit responses offer a route to exact quantum models
A preprint describes a way to turn impedance and admittance data into Hamiltonians and reduced models for superconducting circuits.
Mathematical analysis rules out a class of real-frequency modes in Kerr
Preprint: A Fourier-based proof finds only the zero solution under the study's stated conditions.
Preprint ties plane-curve poles to Bernstein-Sato zeros
A mathematical study reports the plane-curve inclusion and matching motivic and topological pole data, while higher-dimensional examples expose clear limits.
New statistical method reduces bias when models are slightly wrong
Preprint: The paper combines bias correction and empirical-Bayes shrinkage, then tests both in simulations and a schooling application.
Three canonical-basis partitions coincide in a math preprint
The theorem-driven work also identifies an open-Richardson subset with a Demazure intersection and gives a type-A weight criterion.
Mathematical preprint links an infinite matrix to two KP systems
A formal construction connects positive and negative flows, Grassmannian coordinates and special Cauchy-matrix solutions.
EVEREST leads benchmark for mapping social features in cities
Preprint: EVEREST recorded the top overall scores on SocioSeg, but the evidence remains limited to that benchmark and internal tests.
Math preprint proves even-count rule for spin-curve boundaries
Preprint: The work links Ramond boundary points to finite measures and recursive volumes, while leaving a key geometric identification open.
AI method posts higher scores when correcting flawed reasoning
A preprint describes DCGC, a masked-diffusion system that selectively uses information from an earlier draft across maths, code and knowledge tests.
Lattice transport models point to an inverse-square scaling pattern
Preprint maps activity, density and scaling in exclusion processes from one to three dimensions.
AI audit method flags hidden shortcuts in medical image models
Preprint tests ICON on synthetic data, skin images and brain imaging models, finding lower simulation error and clearer signals about artifacts and correlations.
Quarter-flux lattice model yields exact quantum geometry
An arXiv preprint reports a single-particle calculation that finds four paired bands and a lowest band close to, but short of, an ideal geometric limit.
A Recommender Lets Natural-Language Requests Shift Rankings
Preprint: CRAMER reports stronger offline ranking results across four processed datasets with much lower added inference overhead than REARANK.
Study finds RSV common across English care for young children
Among 2,000 children under 3 with respiratory symptoms, RSV positivity was linked to more hospital care and higher healthcare costs.
