Preprint finds fluid-dependent sonic points around a deformed black hole
Calculations compare idealized fluids around a deformed black hole, while the paper reports different values in its prose and table for some cases.
Medical AI method links uncertainty to features in each prediction
Preprint: egRUE scored strongly on four medical datasets, while a five-expert study linked explanations to better-calibrated trust, not patient outcomes.
AI Models Struggle to Rebuild How Chinese Internet Words Are Made
Preprint: A benchmark of 4,759 Chinese neologisms finds a sharp gap between explaining a word and reproducing the form behind it.
Polymer models track faster creep and a shifting load-carrying structure
An arXiv Preprint reports that self-consistent and finite-element models reproduced the experimental trend in amorphous PEI near its glass transition.
Quantum circuit estimates particle scattering and interference
A preprint reports a classical simulation of a quantum circuit that estimated Drell-Yan cross sections and interference, while exposing gaps in angular coverage and a heavy sampling burden.
MPC method bounds disturbance reserve before full solve
A preprint describes an online certificate that trades tightness for computation in two constrained linear-system benchmarks.
Linear AI model points to critical behavior at a learning threshold
An arXiv preprint reports that average error stays finite while fluctuations in learned parameters become singular in a stylized in-context learning model.
Preprint sees starspot shifts in extreme contact binaries
A study of 11 eclipsing systems reports light-curve reversals, mixed orbital-period changes and models that miss the shortest-period targets.
New bounds map a threshold in composite hypothesis testing
Preprint: A mathematical framework gives finite-sample bounds and identifies when Type II error falls toward zero or converges to one as the Type I decay rate lies below or above a threshold.
AI model scores higher at finding camouflaged copper-tube defects
Preprint: CF-YOLO scored higher than YOLOv11n on three CTDD measures, while results were mixed on the external NEU-DET benchmark.
Trace BSA linked to disappearing satellite drops in liquid threads
Preprint: A laboratory study reports a centered neck and no satellite drops at 0.1 g/L BSA, with surface measurements and modeling pointing to a distinct late-stage thinning regime.
RISC-V FFT Tests Show juFFTe Gains, While Zen 5 Leads
Preprint: Tests found juFFTe ahead on several RISC-V configurations, but AMD Zen 5 led across the full transform-size range.
Particle-learning method reports better mixing in model tests
A preprint says its partially collapsed sampler matched a higher-cost full marginal method in simulations and mixed better than JAGS in one Norway Alpha-outbreak analysis.
Wireless AI System Cuts Image Data by Generating Missing Tokens
Preprint: The adaptive method reports strong semantic image scores at very low bitrates, but its receiver decodes far more slowly than SwinJSCC.
Graph structures reveal exact values for the diagonal F-threshold
Preprint: The study gives exact formulas for cycles, bipartite graphs and other families, while bounding the value for arbitrary graphs.
Non-Centred Volatility Models Score Better on Forecast Distributions
Preprint finds non-centred volatility scores 6% to 15% higher on density forecasts, while point-forecast differences stay below 1%.
Atmospheric-Neutrino Simulation Predicts Thousands of Single-Signal Events
Preprint: A Monte Carlo study estimates how atmospheric neutrinos could produce prompt-only events in a large liquid-scintillator detector, and where model uncertainty is greatest.
Preprint reports H-band interferometer signal at 188 pW per nanometre
A laboratory proof of concept reached a signal-to-noise ratio above 2 in 0.4 milliseconds, but it tested only one H-band spectral channel.
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.
