Preprint Reports Core Connectivity and Shortest Paths in SDN Test
A virtual model of Unsoed's three-router core reports interconnected switches, attached hosts and shortest-path forwarding, while physical and link-failure tests remain ahead.
Mandarin speech test reports gains, but wordplay stays difficult
Preprint: An inference-only evaluation reported lower error in some homophone and HumourPhone comparisons, while full homophones remained difficult.
J-PARC Beamline Reports 98% Pure High-Momentum Muons
Preprint: A 12-setting J-PARC test measured beam intensity, spread and purity across three upstream momenta and four downstream scaling factors.
GPU Solver Finds Lower-Cost UAV Routes in Farm Simulations
Preprint reports lower flight-time costs and sub-second runtimes in simulated agricultural grids, but no field or flight tests.
Adaptive AI bias checks show smaller accuracy losses in tests
Preprint: Adaptive timing retained more answer accuracy in some tests, but a white-box signal often changed answers that were already correct.
APT accelerator reports faster 4K AI image generation
Preprint: APT pairs attention-guided pruning with mixed precision and reports major gains at high resolution, while its hardware evaluation uses simulation and modeled energy.
MOTIF recommender reports gains, especially on cold-start items
Preprint results from three sparse datasets report modest overall gains and larger gains for items whose training interactions were masked.
Simulated UAV routing proposal delivers more packets on time
This preprint reports about 96% cumulative packet arrival by the deadline for MAPPO-DM in modeled UAV networks, ahead of three multipath baselines, with evidence limited to simulation.
Screen-reader users covered more documents with linked pages
Preprint: In a 16-person comparison, direct document browsing reached more distinct documents, while the AI interface showed more connected exploration.
MTAR Reports Faster Training and Lower FID Than LlamaGen
Preprint: ImageNet tests report up to 0.95 lower FID and 39% faster training for MTAR than LlamaGen, with no change to inference.
Source checks identify 76 confirmed blends among 225 candidates
A preprint dated 27 August 2026 reports a 33.8% false-positive fraction among the candidates examined, with corrected source identifications and periods.
AI Physics Benchmark Finds Accuracy Falls at University Level
Preprint: OmniPhys tests multimodal models on Chinese physics questions, reasoning tasks and diagram generation.
Many cryo-EM runs outperform one-shot reconstruction on mixtures
Preprint: An ensemble of reconstruction jobs reached 97.4% accuracy on a 45-class synthetic test and separated four major ribosomal states from junk.
New framework links p-adic homotopy to algebraic geometry
Preprint: A theorem-driven study sets algebraic tests for when p-complete spaces and étale homotopy types can come from finite CW complexes.
Wireless method detects blocked RIS panels in moving-user tests
This preprint reports active-RIS identification probability above 95% and higher weighted sum rates under tested blockages and mobility.
A Math Preprint Shows a Proposed Boundary Eigenvalue Bound Can Fail
A constructed family of hemisphere metrics slips below the proposed threshold, while separate conformal and rotational analyses find obstacles to boundary-area counterexamples.
Agent-routing method posts higher task success with fewer request messages
Preprint simulations found that SPFR retained 97.63% of a global comparator's Utility while using 81.24 times fewer request-triggered messages.

Preprint: Researchers catalogue construction activities and test selected robot skills on a laboratory arm and hand.
Math preprint links stable-pair series to framed-sheaf formulas
This arXiv version-1 preprint reports proved local Hirzebruch identities, while its projective-plane results remain conditional on two conjectures.
