New SDE scheme keeps computed values nonnegative at any step
Preprint: The analysis reports nonnegativity for any time-step and first-order strong convergence for sufficiently small steps under stated assumptions.
Simulated satellite uplink method needs fewer than half the pilots
A preprint reports lower channel-estimation error, lower bit-error rate and higher achievable sum rate for an estimator tested in modeled non-terrestrial network uplinks.
Trust-aware planning linked to lower simulated robot-routing backlog
Preprint simulations found the fused monitor had the lowest routing cost and fewest active adversaries, while results depended on planning horizon and cooperative capacity.
A CT model with diffusion pretraining shows sharper organ maps
Preprint: An arXiv study reports higher overlap scores and more precise boundaries on abdominal CT scans, including when fewer expert labels were used.
Preprint: Quantum workflow resolves glueball-like states in a gauge model
A structured calculation on a finite periodic lattice tracks the lightest state's changing spatial profile and tests a compressed route to excitations.
Preprint proposes a seven-dimensional model for cubic-surface moduli
The paper claims a global isomorphism for the relative moduli space and reports 72 isolated points over the smooth stratum.
Preprint tests spatial AI for satellite temperature and humidity profiles
The study reports lower error variability than a pixel-by-pixel baseline, with the largest reported spatial-context difference associated with retrievals below cloud tops.
Muon scans estimate charge and damage in silicon carbide
Preprint: A laboratory study reports a simulation-based muon calibration for effective free-electron concentrations, alongside depth-dependent depletion and damage signals in n-type 4H-SiC.
Tests find lower jailbreak success with a runtime safety layer
Preprint: An arXiv study reports lower judged harmful-output rates in controlled tests, alongside more false refusals and a measurable serving cost.
Localised model usually leads renewable-energy forecast tests
A study of three sensor datasets found SPALT usually had the lowest errors, but STAEformer led on MAE and RMSE for one wind-power-plant dataset.
Mathematicians map when a critical equation has a solution
An arXiv preprint reports existence for positive λ and nonexistence for λ ≤ 0 under tightly specified assumptions.
A new AI model locates unseen actions from skeleton data
Preprint reports mixed benchmark results after training with video-level labels; the method scores individual actions without instance-level pretraining labels.
Simulation points to a 48-step horizon for solar microgrid control
An arXiv Preprint reports that a 48-step horizon had the highest simulated solar self-consumption, alongside the heaviest battery use.
Higher-order Higgs effects could tighten self-coupling bounds
A new preprint reports that loop-level corrections can materially change how experimental limits are translated into Higgs self-coupling constraints.
Model predicts one-way edge light in a topologically trivial crystal
Preprint simulations report one-way edge states inside the bulk continuum in a topologically trivial honeycomb design.
AI safety preprint reports low attack rates for ReDiR defense
An arXiv preprint reports low attack success for ReDiR in controlled tests of tool-using AI agents.
New model preserves linear physical rules in field forecasts
Preprint: Row-CMO keeps required linear relationships intact and posts the lowest reported errors in two simulator tests with limited training data.
Difficulty-aware augmentation posts higher scores on two datasets
Preprint: A 2026 arXiv study reports stronger scores across three model types, but the method took longer to run and was tested on two datasets.
Cloud simulation reports lower power and higher simulated profit
Preprint: In two benchmark traces, OP-PMF+ reported lower power use and higher simulated profit than OP-PMF−.
