Preprint reports faster simulations of graphene heat transport
A synthetic iterative scheme converged faster than conventional source iteration in deterministic tests, while matching the same discrete results.
Simple color forecast beat trained models on unseen copper
Preprint: A two-recording test found that a parameter-free color extrapolator beat trained forecasters on an unseen copper specimen.
Review Links Lead Perovskite Transport to a Soft, Shifting Lattice
Preprint review says one soft-polar framework may connect unusual transport, screening and lattice motion, but defects and polar order remain unresolved.
Robot Study Finds Gesture Commands Hold Up Better in Unseen Tests
Preprint: One pretrained robot model had higher success with language-plus-gesture and gesture-only commands than with language alone in several unseen tests.
Blue Field Ultra-Diffuse Galaxies Resemble Dwarfs in Star Formation
Preprint: Spectroscopy confirmed nine of 17 blue field candidates as ultra-diffuse galaxies, while dust and aperture corrections affected classification and estimated star formation.
Preprint: Photon emission varies more by exit charge than target material
A laboratory coincidence experiment tracked photons from helium ions transmitted through carbon, silicon and silicon carbide.
Preprint reports higher LLM scores with NVFP4 scale refinement
Tests across text-only Qwen3 and LLaMA configurations reported higher suite averages while inference cost stayed unchanged.
Microfluidic test untangles surfactant adsorption and transport
Preprint: C10 E8 showed an adsorption-sensitive pattern, while SDS was better described when short-lived transport beneath the interface was included.
Preprint offers conditional test for large-exponent Fermat solutions
A conditional analysis excludes relevant solutions at sufficiently large prime exponents in selected number fields and identifies an imaginary quadratic family with relative density 5/6.
Adaptive forecast weighting leads three datasets, but not all
Preprint: An arXiv manuscript dated 28 Aug 2026 reports the best aggregate losses in three online datasets, but mixed rankings across M4 regimes.
New finite-field polynomial family comes with exact counts
Preprint: The new family has a group whose non-identity elements have no fixed points, an explicit companion polynomial and exact formulas for related families.
New Bounds Clarify How Harmonic Maps Behave in the Unit Disk
A theoretical preprint reports Hardy and weighted-Bergman guarantees for broad, quasi-subordinate and odd mapping classes.
High-order wave model stays stable through 50 periods in most tests
An arXiv preprint reports a high-order method for nonlinear water waves, including one much faster comparison and a highly nonlinear wall case that broke down.
A model predicts a time crystal with a self-formed oscillating boundary
A theoretical preprint reports a vacuum-like region and a chaotic bulk separated by a sharp front that oscillates regularly.
AI agents score higher with verifier-guided training, preprint reports
A preprint reports higher scores on two benchmarks using a method designed to trace useful earlier actions without rewarding an incorrect final decision.
Audio AI Study Finds Different Embeddings Suit Different Tasks
Preprint: A computational study found that a transformation embedding performed best in retrieval and style transfer, while a processed-audio embedding was stronger at probing processing details.
Robot video models can look right while getting the scene wrong
Preprint: A 3D benchmark ranks Cosmos highest on composite scores but exposes gaps in spatial state, motion accuracy and task execution.
Prototype chip circulator reaches more than 40 dB isolation
Preprint: Simulations and microwave measurements report tuned cancellation of two leakage paths, with circulation reversal within 0.6 nanoseconds.
New theorem links wave energy to boundary data on general domains
Preprint: A proof for singular wave equations on general domains bounds initial energy from a Neumann trace, but does not establish boundary controllability.
