Abstract
The development of effective microscale thermal management solutions is important to further advance microscale electronics because of increasing heat flux densities in these devices. There is an increasing trend towards liquid based cooling solutions because of their much higher heat removal capacities compared to air cooling methods. Electrohydrodynamic (EHD) micropumps are ideally suited for these applications due to their small form factor, low power consumption and ability to work with dielectric heat transfer fluids. In addition, EHD micropumps have no moving parts and are amenable to conventional microfabrication techniques. Current EHD micropump designs, however, generate very low flowrates and pressure head to be practically useful. Here, we demonstrate for the first time, that an asymmetry in the electrode geometry (both 2D and 3D) will result in significantly higher pressure generation with lower power consumption than conventional symmetric electrode designs.

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
