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.
Preprint links legal-school filtering to better Arabic Islamic-law search
In a 503-question benchmark, filtering by school was associated with the largest reported gains on school-specific questions; generated-answer quality was not tested.
Preprint finds a boundary mass as diffusion vanishes in moving models
A one-dimensional mathematical analysis derives a dynamic boundary law and suggests competing stable states, while leaving broader cases unresolved.
Preprint maps when layered spheres are predicted to resonate
Idealized acoustic calculations link resonance regions to shell thickness and impedance contrasts, while identifying a high-impedance region that remains non-resonant.
Preprint finds quantum ‘jamming’ is either trivial or permits hidden signaling
A mathematical analysis says the proposed extension either reduces to ordinary quantum behavior or conflicts with no-superluminal signaling.
Preprint: A Wider Quantum Circuit Can Shorten Spin-Simulation Runs
A computer study found that redundant qubit registers reduced modeled circuit depth and improved noisy spectral signals in some cases, but the circuits were not run on hardware.
Preprint reports sub-sample timing accuracy in simulated high-mobility OTFS link
The proposed pipeline also stayed within less than 2 dB of a perfect-CSI reference, but the study tested a modeled single-user system rather than physical hardware.
Preprint explains when random particle systems follow fluid laws
The mathematical notes link large-scale density averages to deterministic equations, while showing that fluctuation scales depend on the model and dimension.
Preprint reports lower prediction errors from a two-stage neural-network method
The approach learns a shared pattern from pooled data before modeling each group’s differences, with favorable results in simulations and two real-data tests.
Preprint: AI model learns to vary reasoning effort across maths problems
A three-mode router used fewer tokens while staying near its base model’s MATH-500 accuracy, but the evidence comes from one model and a limited set of benchmarks.
Preprint narrows where sphere-valued maps can become singular
A mathematical analysis gives sharp dimension limits and shows that some stable tangent maps must be constant.
Preprint reports faster classification-tree training with a smaller split search
DICS recorded large reported speedups on synthetic and benchmark tests, while accuracy remained comparable in some comparisons and fell in others; regression was not evaluated.
Preprint outlines exact quaternionic quantum operations, but no unique octonionic continuation
A formal study represents quaternionic states, channels and error correction in constrained complex spaces while comparing octonionic frameworks that preserve different operational structures.
