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.
Jet model reports saturation-like scaling in heavy-ion jets
This preprint reports sizeable differences in illustrative RAA estimates between LHC-like and RHIC-like scenarios.
New construction disproves a broad bound in group theory
A preprint constructs countable torsion-free groups that violate the bound, while leaving the finitely generated case unresolved.
QCD framework links jet energy loss to color decoherence
Preprint: An arXiv study models how vacuum radiation and a quark–gluon plasma can be treated in one evolving picture.
Privacy noise helps protect data but can block recovery, study finds
Preprint: A mathematical analysis identifies a lower-noise regime for recovering a bounded hidden distribution and a square-root-scale regime where uniform consistency is impossible.
Sentence-level context tops a multimodal AI benchmark
An arXiv preprint reports its highest tested scores when visual elements are paired with reference-sentence context and document-level global context.
Strong Guide Fields Point to a Different Route for Particle Acceleration
Preprint simulations link approximately log-normal particle energies to charge-starved current sheets in relativistic plasma turbulence.
