A fast, narrow jet emerges from compact source SMA3
An arXiv preprint reports a bipolar SiO jet in SMA3, with speeds near 80 km/s and signs of disk-wind structure.
Scientific Text Reconstructs Much of Reactome's Global Shape
Preprint: Embeddings from Reactome titles and descriptions matched the database's broad topology, while individual biological links remain unverified.
Control method finds feasible shared targets for mixed robot teams
Preprint: A distributed controller jointly plans inputs and a common feasible equilibrium, but its guarantees depend on exact optimization and stated assumptions.
Language-Model Agent Societies Match Early Human Averages, Then Diverge
An arXiv preprint finds that some open-weight models match early human anchors, while later behavior and incentive responses often diverge.
Fiber-optic Bell test reports a strong violation of local realism
Preprint: A laboratory experiment cleared the CHSH benchmark by more than 265 standard deviations, while the detection loophole remained open.
Particle-collision data resist a single explanation for the “horn”
Preprint: A model comparison finds different frameworks fit intermediate and heavy collision systems, while small systems remain unexplained.
Video AI Cuts Video-Localization Time 79-Fold in Benchmark Tests
A 2026 arXiv Preprint reports faster decoding and higher benchmark scores, but the tests used a single 4B backbone and left disjoint events and multiple matching targets unexplored.
OFDM waveform linked to better OOK detection, but leakage remains
Preprint simulations reported lower CP mismatch for most tested sequences, while interference with existing OFDM data varied with channel conditions and signal shape.
One OCR model reports fewer errors across 13 Indic scripts
Preprint: UniLipi combines synthetic manuscript lines with real handwritten data, but its accuracy varied sharply between scripts and transfer tests.
More privacy may improve long-term data use, model suggests
Preprint analysis models whether adding privacy noise can preserve a participant pool when leakage is linked to departures.
URIUM Course Uses a Small Language to Teach Compiler Design
Preprint: A proposed 12-session syllabus follows URIUM from grammar and semantic analysis to assembly output across several processor and system targets.
Droplet speed shifts toward pancake-like scaling as slope rises
Preprint: Water droplets moving through oil changed their size-speed scaling before their overall shapes reached the flat, pancake-like limit.
Image generators lose count as crowds grow, preprint finds
A 640,000-prompt benchmark links counting failures most strongly to requested count, while warning that dense-scene scores are less stable.
Preprint finds exact shortest code embeddings over finite rings
The algebraic study gives separate rules for self-orthogonal codes and a single formula for LCD embeddings.
Exact p-values can still disagree under asymmetric models
Preprint: Four exact two-sided methods can produce different p-values, decisions and model-based power when the null distribution is asymmetric.
PLACID coronagraph targets first science after internal tests
Preprint: Internal alignment and preliminary acceptance testing are complete, but on-sky commissioning still depends on TROIA's operation.
New AI decoder guarantees valid syntax, but task scores still vary
An arXiv preprint tests SWYB on JSON, SQL and drone-planning logic across three instruction-tuned language models.
Preprint: Theory predicts large nonlinear magnetization in 2D materials
Calculations suggest orbital magnetization can outweigh spin responses in several two-dimensional materials, but the prediction has not been experimentally tested.
Language model gains on early forecasts of process steps and time
Preprint: D-TAIA matched or improved on LLM and RNN baselines across four public event logs, with the clearest edge on short prefixes.
