A shallow recurrent decoder reconstructed simulated three-dimensional liquid-metal flow fields from sparse, noisy temperature measurements, producing estimates in less than a second after training. Errors were generally low, but some high-field cases produced larger pressure and velocity errors, and the test was limited to a simplified computational model.

A preprint examines whether AI agents can reach practical agreement before exhausting their computational budget. An illustrative five-agent simulation and live deployments using three named models put adaptive communication between ring-only and complete-only strategies, while a tight-budget run failed and one live run showed disagreement rising.

A modeling study proposes a global, six-zone climate classification for photovoltaic modules by combining simulated annual energy yield with simulated module lifetime. It finds different top-ranked climate inputs for the two outcomes, while small changes to feature-importance scores can alter the cluster structure.

Across 46 mostly rural communities in 28 countries, wealthier sharing units generally had more support ties and connections to relatively wealthier units. Communities with greater wealth inequality also showed more separation between wealth groups in their networks, but the cross-sectional evidence cannot establish cause and effect.

A new traffic-forecasting model reported the lowest errors in tests with complete data and remained first when 80% of entries were randomly masked. It also ran faster than the compared methods, though the evidence comes from two datasets and incomplete-input comparisons covered only methods that could process missing data.
