Corrugated h-BN Layer Linked to Faster Electron Relaxation
Preprint measurements at two metal interfaces found shorter-lived image-potential-state signals on the more strongly corrugated layer, while the substrates differed in other ways too.
Preprint maps a new route to counting complex boundary patterns
Theoretical work derives exact generating-function identities for plane hypermaps with mixed boundaries, while leaving broader cases open.
An Explicit Quandle Construction Challenges a Symmetry Conjecture
Preprint: A mathematical paper builds a connected example with multiple good involutions and shows when these structures split into component-level choices.
Fair scheduling gets harder as planning days increase
Preprint: Formal results show different fairness measures become computationally difficult at different horizons.
Conventional video models lose motion information across appearance changes
A preprint comparing people, macaque brain signals and AI architectures finds that strong scores on ordinary videos can hide weak motion representations.
Pulsed Readout Linked to Lower Correlated Noise in Potassium Sensor
Preprint: A laboratory test reported lower probe disturbance and nearly two orders of magnitude of coherent technical-noise suppression.
Quiet Antarctic STEVE event linked to satellite signal changes
Preprint: An analysis of one 2019 event reports GNSS signal fluctuations, but leaves their cause and navigation impact unresolved.
TB cough AI performance drops on some outside datasets
Preprint: A three-dataset evaluation found weaker external performance for TB cough models, while a clinical-variable baseline transferred more consistently.
Zebrafish Study Links Spinal Sensing to Synchronized Swimming
An arXiv preprint links feedback from zebrafish body bending with swimming coordination, using live-fish experiments, simulations and a robot.
Benchmark replay finds when LLM judging beats majority voting
Preprint replay of stored benchmark pools found judge-guided selection was higher when correct candidates were rare or intermediate, but lower when they were common.
AI CT Model Offers a Way to Audit CT-Based Health Predictions
Preprint: A retrospective modeling study reported higher held-out scores than comparison models and similar average performance after clinician-defined restrictions were applied.
Sampling accounts for part of medical-imaging fairness gaps
An arXiv preprint dated 26 August 2026 tests how much race and age differences could arise under exact fairness before an intervention is chosen.
Privacy budgets may help firms learn while limiting third-party inference
Preprint: A theoretical framework links differential privacy to exploration, exploitation and firm-wide budget allocation, but its evidence is simulation-based.
New method maps resonance shifts in open acoustic resonators
Preprint testing a Green-function method finds close agreement with analytical and finite-element calculations in a two-dimensional cylindrical model.
Greedy string algorithm hits a factor of two at length six
A new arXiv preprint also gives the exact worst-case ratio for three-character strings, while leaving several cases open.
Preprint reports secret keys from a deployed fibre-free-space link
A Padova testbed combined a 620-m atmospheric segment with deployed fibre; reported rates were 0.42 Mbit/s for coherent states and 0.93 Mbit/s for squeezed states under different channel conditions.
DECOWAM reports 58.2% task success on one quadruped–arm platform
Preprint reports lower frame and action errors than Original FastWAM at 50k steps, while X-VLA had the lowest reported action errors on the same 23-episode slice.
Simulations find symmetry rule for switching waveguide light modes
An arXiv preprint models vertical mode switching and horizontal routing, but its higher-confinement design shows leakage into a third mode when writing errors break symmetry.
AI-refined driving system performs best in CARLA simulation
Preprint: V3 followed three rounds of offline large language model feedback and ranked best among four versions on reported lane tracking and curve progress in CARLA.
