Preprint reports collapse suppression in a singular quantum model
The theoretical study reports different outcomes for cubic and quintic self-repulsion, along with localized states in steep outward-pushing potentials. No experiment is included.
Preprint: Staged AI training scores higher than direct fine-tuning in most tests
The IAR method showed stronger document-question and general-benchmark scores in seven of eight main settings, but every checkpoint came from a single training run.
Preprint: Fast networks were only part of the picture in Earth-observation tests
An on-premises system built around a 100 GbE fabric moved data at high aggregate speeds, while measured throughput varied with endpoint hardware and remote network paths.
Preprint links Floer theory with free-loop spaces
A mathematical paper presents MU-module and framed sphere-spectrum equivalences for cotangent bundles, while finding that sphere-level base-change does not generally recover the MU result.
Preprint: Surgical AI model performs better when it forecasts future scenes in chunks
In robot-assisted prostatectomy videos, chunked forecasts also kept predicted instrument paths closer to the benchmark, although long-range errors remained.
Preprint finds sleep-signal maps differ by sex and age
A model of 105 clinical HSAT recordings found recurring links alongside subgroup differences, but the observational results are not a clinical rule.
Preprint reports a fast test for differences across thousands of variables
The logistic-regression approach performed strongly in selected simulations and found evidence of unequal mean vectors in two gene-expression datasets, while its formal guarantees depend on strict assumptions.
Preprint tests whether a tiny dark-matter component could boost early structure
The model predicts more high-redshift halos and lower fitted star-formation efficiency, but combined cosmological data do not significantly favor it over ΛCDM.
Preprint finds AI self-training gains can be measurement artifacts
An audit found apparent changes in an unchanged model, while external distillation reached more low-base problems than the tested self-training methods.
Preprint: Frame choice can make strong dissipation look weak in a warm-inflation model
A theoretical study reports quantum-dominated fluctuations even when the defining frame is strongly dissipative and the model’s temperature exceeds the Hubble scale.
Preprint finds radiative-correction methods diverge most in SIDIS spin calculations
Two theoretical approaches give cross-section differences of about 2% to 7% at selected settings, while some radiation-related spin comparisons are far larger.
Preprint proposes a guard against unsupported physical precision in sparse models
The method keeps competing dictionary explanations in play and reports only the finest physical conclusion they jointly support.
Preprint links electron-drift oscillations to instability in laboratory reconnection
Laser-driven plasma measurements and models point to lower-hybrid drift instability, while key details remain unresolved.
Preprint tests a single-stick control system for tilt-wing eVTOLs
Simulations and early simulator feedback point to stable flight across phases, but the evidence does not yet show lower workload or real-aircraft performance.
Preprint sketches two-point route to recovering wave phase
A mathematical method uses a spherical reference wave to estimate a radiation solution’s far-field pattern from total-field intensities, while leaving finite-distance performance untested.
Preprint proposes a new way to build wave packets in quantum billiards
The formal method continues eigenfunctions beyond the boundary, but its numerical accuracy and long-term localization remain untested.
Preprint finds a 5.4% mismatch between two BAO catalogues
A radial cross-check found that the main SDSS transverse compilations did not agree, while one showed far more scatter than its quoted errors suggested.
Preprint shows restricted quantum-query algorithms can be simulated classically
Theoretical results cover parallel queries, fixed-round adaptivity and selected two-stage designs, while leaving fully adaptive algorithms unresolved.
Preprint proposes fixed power-factor settings for uncertain power injections
A mathematical model finds a closed-form cancellation setting that reaches the best possible worst-case voltage result when specific feasibility conditions hold.
