Drone controller reaches target in simulated clutter
Preprint: In simulation, a viability-kernel MPC system guided a fully actuated hexarotor around static obstacles, with reported iteration times below its 20-millisecond sampling period.
RF-DETR transfers better than tested CNNs to close-range weld images
An arXiv preprint reports stronger close-range transfer for RF-DETR than tested CNNs, while three-seed CNN scores were lower on shop-floor imagery.
Preprint derives Gaussian bounds for Hilbert-space U-statistics
The mathematical framework also gives bootstrap rates and a minimax separation rate for dense Kendall’s tau alternatives.
Porous Ice Shows Different Water-Loss Signals by Wavelength
Preprint: Infrared tests found the same restructuring pattern across three ice vibrations, while water-desorption signals varied sharply by wavelength.
Sparse sampling linked to slower functional linear regression rates
Preprint: A pooling-ridge estimator is paired with matching bounds and tested in simulations and two datasets.
AI pipeline retrieves relevant evidence for nearly every zebrafish query
An arXiv preprint tests a system that follows zebrafish genes to corresponding human orthologs and ranks functional and literature evidence.
Data-only AI clustering beats mean prediction in synthetic tests
Preprint: In synthetic tests, the method came closer to one of several valid outputs than random labels, but it remained behind a benchmark using true modality identities.
GPU Kernel Study Reports Up to Twofold Gains in Matrix Solves
Preprint testing on three accelerators reports peak speedups of 2.05× over cuBLAS and 2.06× over rocBLAS.
Preprint model tracks tape temperature during dynamic process changes
The simulation reported a 4.02°C RMSE against measurements, but its parameters were tuned on the same trajectory used for testing.
Preprint method shows sharper phantom images while learning sound-speed corrections
Testing found sharper phantom images and visible vessel structure at 12.5% detector retention, while validation remained limited to simulated and physical phantoms.
AI Agent Design Separates Audit Trails From Raw Data Sharing
Preprint: An arXiv paper outlines field-level controls for limiting identifying details, while tests and a reported failure expose important trust gaps.
FedQoS stays close to centralized prediction in simulation
Preprint: In a physics-based campus simulation, FedQoS remained close to centralized prediction in two non-IID conditions, while access-selection results differed between mild and severe tests.
Offline AI shows gains in simulated multi-drone fleet tests
Preprint: An arXiv version-1 study dated 26 Aug 2026 reports higher return, communication and sensing measures, plus lower collision-risk counts in modeled multi-UAV tests.
Neural Network Builds Compact Formulas for Quantum Energy Levels
Preprint: In spin-chain tests, the model made compact formulas but did not beat a known quadratic basis on accuracy.
AI dataset method tops three fine-grained image benchmarks
Preprint: DeCO had the highest reported accuracy at low image budgets, but the results lack formal uncertainty tests and no public code was reported at submission time.
Underwater image scores can rise as 3D surfaces deteriorate
An arXiv preprint comparing five systems found image scores diverged from geometry measures in murky water and on an operational survey.
Preprint: Qubit readout reaches 97 ns in an operational test
A single-transmon test paired a 58-nanosecond measurement with 0.17(1)% assignment error and mean leakage of 2.7(2) × 10^-5 per measurement.
ATLAS finds tZq top-quark production in line with the Standard Model
Preprint: ATLAS reports its most precise tZq study yet, with cross-section measurements, spin information and limits on nine dimension-six coefficients.
Open-source tool tests Vietnamese text for signs of AI writing
A preprint describes a Vietnamese detector that accepts scanned and long documents, while its authors say human review remains essential.
