Study models how cities could split AEDs between sites and cars
Preprint compares fixed-capacity stationary, mobile and hybrid AED deployments using emergency incidents, AED inventories and vehicle trips in New York City and Toronto.
Semantic Overlay Shows Sharp Drop in Prompt-Injection Success
Preprint: Tests of a learned overlay reported lower attack success on frozen Qwen and Llama models while returned passages remained highly similar.
Study finds each extra ReLU layer can create an exponential width gap
A preprint uses recursive constructions to show a depth advantage for every adjacent fixed-depth pair, while leaving the relevant regularity regime unresolved.
Quantum framework separates wave-particle structure from its physical scale
Preprint: A mathematical construction links position and momentum through Fourier duality and uses the canonical commutation relation to set the physical scale.
Robot Tests Report Higher Success With Visual Tracks
Preprint: The system reported higher task success than listed baselines in simulation and physical manipulation, alongside stronger future-video prediction scores.
Preprint turns multi-view images into editable 3D objects
ExMesh++ builds a mesh first, then estimates surface materials and lighting on fixed UV maps for later editing and relighting.
Gravity Preprint Finds Two Basic Directions for Splitting a Connection
A formal study recovers Palatini dynamics when a scale condition is met, but leaves the wider non-integrable sector without a clear physical meaning.
Model Finds Thermal Fluctuations Help a Two-Control Scallop Move
Preprint: A mathematical model finds that a hinged swimmer can show directed motion when its angle and stiffness are cycled together.
Deeper lookahead sharpens decisions in hidden-state bandits
Preprint: A lookahead approach cut approximation error in tests and restored the exact arm ranking at depth two, but the evidence is computational and limited.
Exact FullCP Regions Can Be Nonconvex, Study Finds
A preprint finds frequent but shallow nonconvexity in two-dimensional tests and develops certified radial bounds under stated assumptions.
PRQ-KMeans Reports Higher Search and Recommendation Scores
Preprint: The method outperformed RQ-KMeans in an industrial search test and across four public recommendation benchmarks.
Preprint ties Artin–Schreier stability to Frobenius conditions
An arXiv note reports a conditional theorem: strong local stability follows after an Artin–Schreier base-change when every Frobenius iterate meets the stated condition.
Robot sensor network turns readings into machine-readable data
Preprint: In one robot-based test, a model-based system produced semantically enriched measurements, with most generation within 500 microseconds.
B-decay analysis updates Vcb estimate as tensions remain
Preprint: A global fit of published theory calculations and Belle and Belle II data updates Vcb, but experimental averages for related ratios remain above the theory.
Samarium-Doped Nanopowders Show Huge Dielectric Response
Preprint findings report extreme dielectric-permittivity peaks and point to diffuse phase behavior and interface effects, while key uncertainties remain.
A cavity model reports stronger detector response at low acceleration
Preprint: A multimode-cavity proposal models a tunable atom detector that filters high-momentum modes and responds more strongly at low linear acceleration.
Kuramoto study finds selected finite states approach mean-field limits
This preprint reports that, in a tightly specified model, finite unstable manifolds approach the Ott-Antonsen description at order 1/N.
Quantum model finds a common limit for locating brief changes
Preprint: A mathematical analysis says a square-root measurement can match the best collective strategy for pinpointing one temporary change as sequences grow.
Preprint shows how to round secretary-problem cutoffs exactly
A second-order correction narrows the choice to two neighboring integers in several single-threshold models, while an error band leaves some cases unresolved.
