Abstract
This paper describes geometric coupling of the dynamics of break-up of liquid threads in parallel flow-focusing devices (FFD), which are integrated into a multiple quadruple-microfluidic droplet generator (QDG). We show weak parametric coupling between parallel FFDs with an identical design, which leads to the slight broadening of the distribution of sizes of droplets. Using parallel FFDs with distinct geometries we simultaneously generated several populations of droplets with different volumes, yet, each of these populations was characterized by a narrow size distribution. Simulation of the generation of droplets in the quadruple-microfluidic droplet generator based on hydraulic resistances to the flow of a single-phase fluid was in good agreement with the experimental results.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
