Abstract
In nanosecond pulsed electroporation of biological cells nanosecond duration pulses with high frequency spectral content are applied to the cell. We show that accurate modeling of the electroporation process on these time scales requires considering the effect of the dielectric dispersion on the electric potential across the membrane. We describe the dielectric relaxation of the membrane as dispersion in the timedomain and incorporate it with the nonlinear asymptotic model of electroporation. Our nonlinear dispersive model of a biological cell is solved using a finite element method enabling arbitrary cell structures and internal organelles to be modeled. Simulation results demonstrate two essential differences between dispersive and non-dispersive membrane models: the process of electroporation occurs faster when membrane dispersion is considered, and the required electric field to electroporate the cell is significantly reduced for the dispersive model.

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
