Preprint reports lattice effects alter predictions for a pulsar-timing signal
In a single-field scalar Gauss–Bonnet inflation model, the lattice prediction rose above the perturbative result when primordial curvature fluctuations reached about 10^-2.
Preprint gives an explicit recipe for a class of local Langlands parameters
The theoretical paper matches twisted gamma-factor formulas on the automorphic and Galois sides, with its stated result restricted to essentially tame middle supercuspidal representations.
Preprint finds legal AI often misses crucial information before answering
A benchmark of 10 language models found no system that reliably identified gaps in incomplete legal questions while answering complete ones directly.
Preprint models how moving boundaries alter polymer-translocation odds
An exact Brownian-walker analysis predicts nonlinear splitting probabilities and diffusion-dependent long-time tails; a numerical fractional-Brownian extension changes the exponents.
Preprint finds machine-learning waveforms can bias black-hole estimates
A two-stage model matched its target waveform components closely, but recovery tests exposed systematic shifts when signals came from a different waveform family.
Preprint reports smaller additive errors for private data streams
A theoretical analysis finds gains across several continual-release tasks, but relative error does not ease the hardest adaptive MinSelect case.
Preprint outlines mathematical universal control for qubit–rotor systems
The framework combines qubits with U(1) rotors and applies its constructions to gauge-covariant hopping, direct-angle phase estimation and rotor Fourier circuits.
Preprint reports higher AI segmentation scores across four medical-image benchmarks
PROMISE-CNN scored above U-Net and PROMISE-Txformer generally above UNETR; cardiac agreement was better in one analysis, but clinical performance was not tested prospectively.
Preprint Outlines South Pole Telescope’s Planned CMB Upgrade
The SPT-3G+ receiver targets a six-year survey with deeper maps, faster mapping, stronger lensing reconstruction and more cluster detections.
Preprint says a fully automated economy could grow without human consumers
A formal model links human welfare to ownership of machine production and treats its 30% to 100% growth range as an illustration, not a forecast.
Preprint reports state-dependent quantum revivals in a Rydberg-chain model
A constrained four-body model produces persistent oscillations from one starting pattern, while the proposed atomic implementation remains untested.
Preprint details South Pole receiver designed for nearly 10 times faster mapping
The proposed SPT-3G+ instrument would pack 14 detector arrays into a cryogenic system whose performance remains an engineering prediction.
Preprint develops a framework for tracing sensitivity in infinite-dimensional optimization
The mathematical analysis derives conditional upper estimates for directional subdifferentials of value functions, while showing where stronger geometric conclusions remain out of reach.
Preprint: Tool-Using Multimodal AI Scores Higher on New Rules in Maze Tests
In synthetic grid-maze evaluations, a controller coordinating perception, execution and rule verification recorded higher scores than direct supervised fine-tuning on unseen rules.
Preprint Sets Explicit Bounds for 3-Wise Intersecting Set Families
A deterministic proof using Fourier analysis and entropy limits the size of regular, increasing families of subsets while pointing to room for sharper estimates.
Preprint reports widespread, uneven connectivity differences in autism data
A Bayesian whole-connectome analysis found more extensive negative than positive associations, while leaving causation and biological mechanism unresolved.
Preprint finds no clear link between star formation and galaxy metal content
In selected MaNGA data, stellar mass was more strongly associated with resolved metallicity than local star-formation measures, while calibration assumptions remained an important caveat.
Preprint: Hybrid AI reports 96.9% accuracy authenticating satellite radar signals
The system used a classically simulated quantum circuit and 10% of the corpus, while results varied sharply between satellites and two spoofing scenarios lacked detailed event counts.
Preprint finds the largest intersecting permutation families must be stars
For k≤n^0.25, families without a shared centre are asymptotically no larger than two-thirds of the biggest star; a sharper bound appears when k≤(ln n)^d.
