Mathematical study finds balls minimize a key PDE constant
An arXiv version-1 preprint reports a universal lower bound and sharper results for smooth domains, ellipsoids and annuli.
Model predicts fluffy PET clusters and many smaller particles
A preprint models what may remain after enzymatic plastic degradation, including release times for bottle and textile PET.
Exoplanet Spectrograph Meets Key Stability Test, Early Results Show
Preprint: RISTRETTO’s seven-spaxel instrument covered 617 to 860 nanometres and produced first spectra on sky, but calibration and alignment work remains.
Preprint rules out nontrivial outgoing scalar-wave modes in Kerr-de Sitter
A mathematical proof covers the full subextremal range, while extremal cases and negative-imaginary-frequency modes remain outside its scope.
New four-manifold construction sharpens a key mathematical bound
Preprint presents an infinite family of spin symplectic spaces and a conditional route to the value 8.
Prior scores tied to shifts in AI judges' ratings, tests find
A preprint reports lower numerical scores and altered classifications under anchored metadata, while two tested prompts showed mixed or no clear protection.
Quantum-switch model finds a precision edge over Gaussian probes
Preprint: A single-mode model found that odd-parity protocols could outperform fixed-order Gaussian probes in selected settings.
Model reveals intricate topological phases in six-atom lattice
Preprint: Numerical and analytic calculations map Chern-number changes as two hopping phases vary in a generalized two-dimensional model.
AI Models Agree on Some Shape Impressions, but Not All
Preprint audit finds vision-language models align more on geometric and affective shape rankings than on unrelated descriptions.
Preprint tests a hybrid way to flag risky mini-program screens
A prototype pairs visual checks with network analysis, but the paper reports no quantitative validation of its URL-risk classifier.
Quantum model separates process randomness from memory effects
Preprint proposes a way to distinguish irreducible quantum randomness from randomness that temporal memory can explain.
Tests find AI document paths can expose hidden Office content
Preprint: Tests across Word, Excel and PowerPoint found different evidence reaching models through different document-ingestion paths.
New flow model has lower long-horizon errors across four benchmarks
Preprint: CoKo-UNO records the lowest rollout error in four flow tests, but its accuracy drops sharply when moved from a 32×32 grid to finer resolutions.
AI summarization method is far faster at choosing training examples
Preprint reports much faster example selection than two baselines, while quality results vary by dataset and model.
Satellite model sorts maize stress into four readable stages
Preprint: A study reports promising results in Iowa and Nebraska, but field decisions and yield benefits still need testing.
Calculations point to cooperative neutron pairs in helium-8
This preprint reports energy and wave-function signals consistent with a two-pair quartet in modeled helium-8, while limiting the conclusion to the Daejeon16 interaction and basis used.
Math Preprint Finds Worst-Case Sampling Can Scale Quadratically
A new arXiv preprint bounds how many weighted point evaluations are needed to control distortion in m-dimensional function spaces.
Nearest-neighbour method stands out in high-dimensional clustering tests
Preprint: The approach beat maximum likelihood at larger tested dimensions, but outlier results varied by scenario.
Preprint: Cœuré–Loeb fibration found inside a Stein space
A proof-based construction places the non-Stein example inside a larger Stein space, while leaving the broader open-immersion problem unresolved.
