EV virtual power plant model shows lower error in coupled tests
Preprint: A data-driven inverse-optimization method performed much better when operating constraints on individual resources were coupled.
Industrial linear model remains solvable at 2,000-plant scale
A Preprint reports that LSTN resolved 2,000 plants in minutes, while STN-60 min failed to converge within 2 hours at 20 plants.
Frequency-based tests expose weak points in grid-forming controls
This preprint proposes a dynamic-droop screen that separates grid-forming and grid-following models, while finding oscillations in some grid-forming configurations.
Chest X-ray AI Shows Better Transfer, but Exact Retrieval Falters
Preprint findings show higher NIH-to-CheXpert AUCs with BYOL initialization, alongside low exact-pair retrieval on OpenI.
Analysis finds two 16N spectra do not fit one shared weak-current model
Preprint: The spectra share a strong continuum, but a single common weak-current amplitude does not describe them together.
Preprint Assigns Unknotting Number 3 to Named 11-, 12- and 13-Crossing Knots
Other listed cases are narrowed to three or four, or get a conditional same-sign requirement if two changes suffice.
Dynamic-key encrypted controller stays stable in a computer test
Preprint: A mathematical analysis and one numerical example report stability and no overflow with changing quantization gains, while leaving physical-world performance untested.
Control designs aim to hide a network mode from compromised nodes
This arXiv preprint describes partial-measurement methods and illustrates them in one modeled 11-node network.
New travel model changes simulated outcomes through linked attributes
Preprint: Tested on Seoul and London travel data, the model kept predictive performance near standard benchmarks but altered simulated mode-share responses.
AI Model Combines CT Scans and Records to Classify ILD
A preprint study reports a small, non-significant edge over imaging-only REN, while average routing weights for CT and EHR data remain nearly even.
A three-dimensional lattice Hardy constant matches 1/4
Preprint: A proof on the three-dimensional lattice finds the same sharp coefficient as the continuous Hardy inequality and an explicit positive remainder.
AI study reports lower sycophancy after label-free training
Preprint: A reward built from a model’s own sampled answers was associated with lower sycophancy; the training signal used no ground-truth labels or preference annotations.
Two NbTiN films show more uniform vortices at 7 mTorr
Preprint: In a two-film comparison, the 7 mTorr film showed stronger magnetic and current responses and more uniform, locally ordered vortices.
Fixed OBABO tuning cannot ensure uniform ballistic cold-start total-variation mixing
Preprint: Analysis finds no uniform ballistic cold-start total-variation guarantee for OBABO parameters fixed from curvature bounds and dimension across smooth strongly convex targets.
New framework maps which Maxwell modes actuators can reach
Preprint: The study separates local fields from global circulation and flux, then tests which modes its actuators can reach.
Theory predicts electric test for altermagnetic order
Preprint says a resonance threshold could separate altermagnets from higher-symmetry antiferromagnets, but the signal remains untested.
Preprint prototype rejects Treasury-token minting after assets are encumbered
The Solidity framework matched a simple reserve check in a valid scenario but rejected issuance when encumbered assets were excluded.
Computer search identifies 344 rare-earth magnet candidates
Preprint: A computational workflow produced 344 candidates, with five on the calculated stability hull, while experimental stability was not assessed.
Study points to two superconducting channels in SrSn3 films
An arXiv preprint reports different energy gaps, critical fields and vortex-core spectra linked to surface and bulk channels.
