Abstract

fetched live from OpenAlex

The shape of flexible fibers in a suspension varies depending on the hydrodynamic interaction of each fiber with the flow and with the neighboring fibers. By examining the total fiber forces from direct numerical simulations, this study proposes a reduced-order stochastic model that predicts the three-dimensional shape of fibers settling inertially in a suspension of different concentrations. While at low concentrations gravity is the main contributor to the planar deformation of the fibers, at higher concentrations, the interaction of fibers with each other creates large out of plane deformations.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
