A laboratory study linked BSA-related surface viscoelasticity with the disappearance of satellite drops during liquid-thread breakup. The no-drop boundary shifted with aging time, while high-BSA threads followed an approximately linear late-stage thinning pattern.

The preprint reports stable long-time propagation in most tested cases and favorable benchmark comparisons, alongside 908 runs that exploded in a 1,620-run stabilization sweep and a breakdown in the most nonlinear wall test.

A preprint develops a hidden-symmetry calculation for anomalous scaling in a nonlinear stochastic shell model and finds numerical support in the weak-noise regime, while larger noise exposes the limits of the leading approximation.

A preprint compares flow matching and diffusion with direct deterministic predictors across cavity and cylinder rarefied-flow benchmarks. The generative pipelines interpolated well, but MLP baselines had lower cylinder field-error scores, while physics adapters reduced selected diagnostics without improving aggregate field accuracy.
