Living systems, ecosystems, climate and observation.
Delayed regional totals can support a precise-looking estimate without tightly constraining the hidden state. A six-region synthetic SIR benchmark compares ensemble intervals with validated set bounds, including the cost of bounds that become almost useless.
A system that recovers slowly and an environment that persists can leave the same statistical signature. An exactly sampled stochastic experiment shows what passive monitoring can identify, and which extra observations change the question.
A frozen six-patch EnKF benchmark shows that an explicit aggregate-and-delay observation operator improves synthetic state and peak forecasts, yet undercovers the latent state and therefore earns only a PARTIAL conclusion.
A matched-work experiment asks whether uniform, residual, or goal-oriented finite-element meshes best preserve a growing-domain modal-transition time. In this first smoke test, uniform wins.
A bounded finite-state calculation and seeded direct simulation agree on one synthetic low-copy genetic-toggle event—but that Phase-1 agreement is a starting point, not a rare-event victory.
A controlled audit of when blur, pixel size, segmentation error, and finite windows make Arctic melt-pond images appear to cross a connectivity threshold that the latent surface did not.
