Preprint model reaches 90.1% on human-pose video anomaly test
STEP reports its strongest result on UBnormal, while its pose-only design remains vulnerable to missing tracks and anomalies involving objects or interactions.
Preprint reports compact 3D reconstruction from sparse views under known lighting
A point-based renderer recorded the lowest reported surface-mismatch score in a five-object synthetic benchmark, using 267 optimized surfels on average.
Preprint shows multiplicity one for two root-of-unity maps
An arithmetic proof links repeated complex-map behavior to resultants, congruences and p-adic estimates, while leaving several patterns as conjectures.
Preprint reports tunable mid-infrared emission from black phosphorus
Optically pumped flakes on patterned silicon-dioxide gratings produced narrow spectral lines at room temperature, while a temperature test reported a lower threshold at 110 K.
Preprint reports a compact vision system for matching points and lines
UPAL combines both tasks in one network and reports lower latency and memory use than separate components, though the comparisons depend on specific test setups.
Preprint maps millions of academic affiliations into institutional hierarchies
OpenSubAffil links raw OpenAlex affiliation strings to sub-institutional entities, with stronger results for name matching than for deeper parent-child links.
Preprint reports lower long-range errors for a physics-guided AI model
In simulated multi-object scenes, PhyODE reported stronger trajectory forecasts on several held-out tests, while physical-property estimates worsened under distribution shifts.
Shunt failure linked to sharply higher mortality after newborn heart surgery
A retrospective study of 129 babies with critical congenital heart disease found 21.7% neonatal mortality after modified Blalock-Taussig shunt surgery and identified several perioperative factors associated with mortality.
Preprint: Free-electron laser produces tunable attosecond soft-X-ray pulse pairs
An LCLS-II experiment adjusted pulse spacing in 250-attosecond steps and found spectral evidence of controllable relative phase, while the numerical phase-stability estimate came from simulations.
Preprint reports smaller memory footprints for test collision-avoidance systems
A neural network paired with a corrective lookup table matched the reference policy at every point on two finite grids, but the study did not test full operational specifications or continuous states.
Preprint tests 3D shape reconstruction from a few sound-wave directions
In computer tests of two modeled obstacles, reconstruction quality changed with the number of backscattering directions, while a sea-star test was described as satisfactory with added noise up to 30%.
Preprint derives law for the largest gap in a random eigenvalue cloud
A theorem-based analysis gives an explicit asymptotic description of the most isolated eigenvalue in the bulk of the complex Ginibre ensemble.
Preprint: AI model uses a reference image to find the right moment in video
The system scored higher than selected baselines on new tests, though the evidence is limited to benchmark performance.
Preprint: At best, AI-generated tests caught 30% of dependency breaks
In a filtered Java/Maven benchmark, GPT-4o with Class context detected 27 of 89 breaking updates, while compilation failures averaged 79.7% across configurations.
Preprint reports wide memory window in organic transistors with tiny platinum particles
Laboratory devices showed memory-like hysteresis, step-like current transport, optical writing and electrical erasing; simulations also tested their potential for neuromorphic computing.
Preprint proposes an audit trail for AI research communities
The Symposium framework records agent activity and scientific reasoning in an immutable history, but its examples are synthetic and it has not been shown to make AI-assisted science more reliable.
Preprint reports better weak-target sonar tracking in simulations
A raw-measurement method showed higher track confirmation and lower localization scores than CFAR-based trackers in simulated multipath channels, but was not tested in the field.
Preprint finds rising-systole paths for selected geometric surfaces
Explicit deformations connect square-tiled, hexagon and octagon constructions to maximal surfaces, but the result does not cover every translation surface.
Preprint finds early warning signals for Solana memecoin rug pulls
Models using five minutes of trading data performed better within the same platform than when moved between Raydium and PumpFun, but the authors say the results are not ready for real-world deployment.
