Preprint finds no detectable sideways motion in thin-film domains
Imaging and an idealized model suggest that a Zn–Mg–O film switches mainly through new vertical domains, not detectable sideways travel of an existing wall.
Vapor-deposited decalin glasses show unusual stability
Preprint: Laboratory tests found selected decalin glasses were more stable than liquid-cooled versions under specific conditions.
Two mobility measures in a polymer glass diverged before yield
Preprint: In one lightly crosslinked PMMA film, probe and mechanical mobility measures agreed after yield but diverged sharply as yield approached.
LLMs often answer table questions without enough evidence
Preprint: A benchmark of eight LLMs found silent unsupported answers dominated reliability failures, while robustness varied across table changes.
Pressure study proposes three types of metal-insulator transition
Preprint: Calculations link ionic, covalent and metavalent transitions to different changes in structure, bonding and lattice behavior.
Preprint Reports Stronger Literary Style Matching Across Four Books
A five-axis method maps writing into shared stylistic dimensions and steers model activations toward a target book, with evidence limited to computational tests.
Exciton binding energy rose before palladium-doped films turned metallic
Preprint: In epitaxial PdxCu1-xCrO2 films, the fitted exciton binding energy rose before a continuous metallic network appeared.
Molecular Antenna Transfers Energy Fastest at Moderate Temperatures
Preprint measurements and simulations found a temperature turnover in an APC complex, while optical-dephasing times decreased steadily and the model required a changing low-frequency bath.
Gaucher disease models suggest red cells may struggle in tight spaces
Preprint simulations link modeled red-cell stiffness and shape changes to slower passage through narrow spaces and higher viscosity.
German AI model spots prostate cancer better than it grades it
Preprint: A model trained on archived biopsy slides performed strongly at identifying malignancy in Munich, but its detailed grading scores were lower across three outside cohorts.
Microscopy finds hidden depth changes inside polar superlattice
An arXiv preprint reports that whole-thickness images can mask shifting atomic and polarization patterns in a PbTiO3/SrTiO3 stack.
Tendon boundary sharpened after reloading, but mineral imprint remained
Preprint research in male mice found a sharper mineralization boundary at a new position after reloading, while altered nanoscale architecture remained.
A pooled-data effect may explain human travel’s power law
Preprint: In Chilean mobile-phone data, lognormal classifications rose within users as the pooled displacement exponent steepened during full lockdown.
Computational screen finds 12 new metallic altermagnets
Preprint: Six candidates show calculated spin and Hall responses, but experiments are still needed to test whether the materials can be made.
New method shows lower bias scores in four vision-language models
Preprint reports marked declines in measured race and gender bias while MMStar accuracy stayed within 0.6 percentage points of baseline.
Small Expanding Flow Disturbances Stay Stable in New Preprint
A new preprint presents a theorem for small expanding-flow perturbations, with global existence and a finite-time zero-viscosity limit.
Covariance method matches GLMM influence checks, weaker N-mixture agreement
A preprint tests PosCoSeA, which estimates leave-one-out changes and bootstrap uncertainty without repeated model refitting.
AI unlearning study finds update patterns matter more than size
Preprint results from a pooled checkpoint analysis link forget–retain alignment more closely to recovery after relearning attacks, but the evidence is benchmark-limited.
AI texture tool scores best on three of four reported measures
Preprint: GLOSS fills missing 3D texture areas from local references, while its authors report limited cross-shape generalization.
