Milky Way Survey Finds SiO Ratios Fall as Density-Time Rises
Preprint: A Nobeyama 45 m survey of 258 Central Molecular Zone clouds found all six SiO-to-line ratios were lower at higher values of a combined density-time measure.

Preprint maps quantum symmetric-pair characters into simpler parts
Preprint: The proof-based classification covers generalized Satake diagrams of finite and affine type under stated algebraic assumptions.
Preprint catalogs 350 possible ultraluminous X-ray sources
The first eROSITA search found 90 higher-likelihood candidates and 260 lower-likelihood ones, but uneven coverage, contamination from active galactic nuclei and source confusion limit the result.
Pressure Study Finds Nearly Isotropic Critical Scattering in CeNiC2
Preprint findings show nearly linear resistivity along all three crystal axes near a narrow superconducting dome.
A new method separates Galactic dust from the cosmic infrared background
Preprint: Wavelet analysis recovered dust across three high-latitude Planck patches.
A memory check is linked to higher long-document AI scores
Preprint: A Qwen3-VL-4B agent using AWM-GRPO posted the highest listed scores while its terminal memory was tested for answerability.
Invariant Lie-group flows approach solitons along subsequences
Preprint: An analysis of invariant flows on Lie groups finds subsequential soliton limits, local stability near standard Bismut-flat metrics, and instability in a non-standard example.
Audio model tracks theory-based rankings of musical dissonance
This preprint reports a computer-based representation that closely matched interval rankings but showed weaker, uneven results for some chords and modes.
New framework ranks AI systems across 18 workplace activities
This preprint ranks Gemini 3.1 Pro highest under neutral settings, but its scores compare capability profiles rather than predict task success.
Selected Iron Calculations Report One to Ten Resolvable Exchange Terms
Preprint: Tests of random-spin supercells and spin-spiral directions found different limits for exchange-parameter fitting in bcc iron.
Compact open video planner beats two frontier teachers (Preprint)
The study reports a closed-loop score of 0.924 after verifier replay and offline preference training, with comparisons against three teacher branches.
Study finds lower errors in predictions of unmeasured nuclear radii
Preprint analysis reports lower errors for two global charge-radius models, with prediction-interval coverage near stated levels in a later-measurement test.
Query router reports faster document retrieval with higher quality
Preprint: A query-only router selects among retrieval pipelines and reports a higher top-five relevance score with much lower average latency.
AI model posts faster, higher scores on 3D MRI questions
Preprint reports benchmark results for SeVeR, a system that selects visual information from multi-sequence breast MRI.
Geometry-based model improves hard-sphere predictions in confinement
Preprint: A parameter-free mapping was tested against simulations of unmixing, cavity pressure and nanoscale force profiles.
Factory tests find two distinct signal patterns at 318 GHz
Preprint: Measurements at 11 line-of-sight receiver locations found that strong-reflection and random clusters followed different delay, power and angular patterns.
E-commerce search model reports modest GMV change in test
Preprint: In a 41-day A/B comparison, DCEO showed a 0.36% relative GMV change; the evidence comes from one search system.
Particle-model scan finds strong transitions in LISA simulations
Preprint modeling finds simulated three-year LISA signal-to-noise ratios up to 88, while benchmark thermal choices sharply change the forecast.
Model maps how chemical fuel reshapes a Brownian heat engine
Preprint: An exact mathematical model links chemical fuel, heat and mechanical load, but its predictions have not been tested in a physical motor.
AutoVerifier tops four benchmarks for answer verification
Preprint: The system reached 93.05 macro accuracy; its method turns recurring errors into replay-tested code modules.
