Abstract
The effect of asymmetry in the electrode geometry and interelectrode spacing on the performance of ion-drag-type electrohydrodynamic micropumps was studied. The micropumps consisted of chromium/gold planar electrodes on a glass substrate that was integrated within a polydimethylsiloxane microchannel that was 100 mum in height. The pumps were tested using HFE-7100 as the working fluid for the maximum-pressure generation under a no-flow condition and the maximum flow rate under a no-back-pressure condition. The micropumps with an asymmetric-electrode design, where the emitter and collector electrode widths were different, generated a significantly higher pressure head and flow rate than the corresponding micropumps with symmetric-electrode designs for the same applied voltage. The power consumption of the pumps with asymmetric electrodes was significantly lower than that with symmetric electrodes.

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
