New construction disproves a broad bound in group theory
A preprint constructs countable torsion-free groups that violate the bound, while leaving the finitely generated case unresolved.
QCD framework links jet energy loss to color decoherence
Preprint: An arXiv study models how vacuum radiation and a quark–gluon plasma can be treated in one evolving picture.
Privacy noise helps protect data but can block recovery, study finds
Preprint: A mathematical analysis identifies a lower-noise regime for recovering a bounded hidden distribution and a square-root-scale regime where uniform consistency is impossible.
Sentence-level context tops a multimodal AI benchmark
An arXiv preprint reports its highest tested scores when visual elements are paired with reference-sentence context and document-level global context.
Strong Guide Fields Point to a Different Route for Particle Acceleration
Preprint simulations link approximately log-normal particle energies to charge-starved current sheets in relativistic plasma turbulence.
New Geometry Test Identifies When Tropical Multidegrees Are Positive
Preprint: A conditional projection test identifies positive multidegrees, while augmented Bergman fans also have Lorentzian volume polynomials.
Nonnegative Concave Functions Preserve Lee-Type Schatten Constants
This preprint reports an exact transfer for finite complex matrix families across 1 ≤ p ≤ ∞; the linear constants remain unknown specifically for 1 < p < 2.
New Muon variant uses fewer tokens in Transformer tests
An arXiv Preprint reports lower final validation loss and 13.3%–24.0% token-efficiency gains for SAMuon over tuned Muon in Transformer tests.
Human readers and language models track language trouble differently
Preprint: Conceptual disruptions showed a sharper, shorter pattern, while referential disruptions were more distributed across later reading and model prediction.
One Mathematical Framework Brings Several Plasticity Rules Together
Preprint: A single scalar functional supplies stresses, internal-variable forces, resistance and plastic-flow conditions in a theoretical framework.
AI model posts lower 50-second errors in airport forecasts
A version 2 arXiv preprint reports lower 50-second displacement errors for safety-critical and randomly selected agents on the Amelia-10 benchmark.
Preprint maps how genome length relates to species splitting
A mathematical model predicts distinct critical-length regimes, while finite simulations support the trends without testing them in organisms.
New preprint classifies every crepant partial resolution of the nilpotent cone
Preprint: A proof-based study connects the nilpotent cone's resolution models to Hamiltonian reduction and geometric invariant theory, and extends the construction to deformations.
AI Upscaling Method Reports a Better Image-Quality Trade-Off
An arXiv preprint reports gains on several 4× super-resolution measures, while its evidence remains limited to benchmark comparisons.
A Live WiFi Overlay Maps Signal Paths in Augmented Reality
A preprint describes an ESPARGOS system that turns phase-coherent WiFi measurements into camera-aligned views of arrival angle, relative delay and polarization.
AI heart-rate model leads synthetic tests, but loses edge when ECG fails
An arXiv preprint finds attention fusion had the lowest descriptive overall error, but no pairwise winner survived statistical correction.
AI decoding method reports near-full accuracy with much less compute
A preprint reports about 90% of full-context accuracy on isolated text tests, with 1.3–1.7× throughput at 0.2–0.3× compute.
Voice-memory system scores higher while using fewer tokens in tests
An arXiv preprint reports stronger factual, persona and audio-memory scores, with lower token use at one tested retrieval setting.
Preprint confirms two exact Gaussian coding conjectures
The version-one arXiv paper proves the conjectured formula and rate region, while exact synthesis has higher rates than total-variation synthesis for positive correlation.
