Abstract

fetched live from OpenAlex

Conservative dilational properties of an interface are determined by measuring its deformations in response to static applied forces. A micropipette‐based technique is used to mechanically deform emulsified bitumen droplets. The applied force, required to achieve a given deformation, is quantified through the deflection of a sensitive cantilever. In describing the stress‐strain response, at relatively small deformations, a model is developed that captures the relevant material properties of the interface: These are the equilibrium tension and the dilational elasticity. These material properties of bitumen droplet surfaces, emulsified in an industrially relevant aqueous environment, are examined. It is demonstrated that the dilational elasticity of bitumen droplet surfaces depends on droplet age, while the tension is relatively invariant.

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.
