Multilevel SGD is 18 times faster in one PDE test
Preprint: MLSGD reached comparable accuracy 18 times faster than batched SGD in one reported comparison, while larger runs showed diminishing parallel efficiency.
Machine Learning Helps Find Rare Hot Subdwarfs and White Dwarfs
This preprint reviews machine-learning tools for finding and studying hot subdwarfs and white dwarfs, while stressing that follow-up remains essential.
Quantum model predicts sharply fewer bit flips in a new qubit design
This Preprint on arXiv models a 0–n Fock qubit with exponentially suppressed bit-flip errors as its level number rises.
Study finds a roughly 70-year pattern in Earth's rotation
Preprint analysis finds the signal consistent with a core-related contribution but says the model does not indicate an imminent negative leap second.
Lesion-guided AI posts high accuracy in ovarian ultrasound study
Preprint: A comparison of two public datasets found strong held-out results with less detailed lesion marking than contour-based methods.
GPU Backend Records 11% Speedup in Random-Material Test
Preprint: A larger numerical benchmark showed an 11% GPU speedup, while CPU configurations with more resources were associated with lower gradient-estimator error.
Exact robust-MDP method scales better on two benchmarks
Preprint: The proposed method matched a stochastic-game baseline's values on all tested cases, but the baseline was faster on Frozen Lake.
Game theory study maps when improvement dynamics reach equilibrium
Preprint links weak acyclicity to weak potentials and identifies conditions for finite games to converge through selected moves.
Simulations link black-hole winds to stalled orbits and spin misalignment
Preprint: An idealized simulation suite reported lower accretion, stalled orbital expansion and slower spin alignment in runs with feedback winds.
AI model reports stronger Alzheimer’s MRI results with sparse, unpaired data
Preprint: A two-stage system used tabular scores, PET and separate handwriting data during training, then made predictions from MRI alone.
Simulation study reports less fit bias after mass-resolution weighting
A preprint reports improved truth agreement and smaller fit deviations in two fully simulated decay tests.
Dual-class switches tied to early valuation gains and patent citations
Preprint analysis of US public firms finds valuation gains after recapitalization, while patent-citation estimates grow over time and unification shows the reverse pattern.
AI personality labels varied with prompts and model compression
Preprint: ENFJ was the leading MBTI label across tested open-source models, while reported types varied with prompts, precision and decoding settings.
AI models often get the science right but miss the rules
An arXiv preprint benchmark of 2,527 scientific questions finds that correctness and instruction following often diverge.
Misaligned nanowire shells steer plasmonic hot spots
Preprint: An arXiv study finds that nonconcentric shells give access to otherwise dark resonances and move near-field hot spots toward thinner regions.
New theorem maps curvature, flow and topology in hyperbolic space
Preprint: Under a stated curvature condition, closed hypersurfaces in hyperbolic space admit a terminating flow with surgery and a restricted topological classification.
A guide to elliptic-curve ranks leaves key puzzle open
Preprint offers a concise introduction to two ways of defining rank for elliptic curves, while stressing that the central conjecture is still unproved.
REBELS-25 shows warm and cold gas sharing large-scale rotation
Preprint: ALMA and JWST observations of REBELS-25 find shared rotation across warm and cold gas, while 55% to 98% of star formation is obscured in four regions.
Preprint tests method for separating exposure effects from time trends
Simulations found the design stayed unbiased under one pattern of time-induced confounding, but the authors caution that it is not a general solution.
