Abstract
In this paper, the full nonlinear equations of motion of an immersed glass micropipette driven longitudinally by a piezoelectric actuator are derived, based on Kane's method. The Morison equation is adopted to model the hydrodynamic forces in which the drag force is approximated with a viscous damping force. The model presented shows that the longitudinal vibration of a micropipette results in excitation of its out-of-plane, lateral eigenmodes. The nonlinear dynamic model is in good agreement with experimental observations in the literature. Furthermore, an immersed glass micropipette with imbedded mercury is also considered. Simulation results show that the lateral deflection of a micropipette tip increases by adding mercury. This result, however, is inconsistent with the experimental results. The discrepancy is possibly attributed to the assumption of zero relative motion between the mercury contained in the glass micropipette and the glass micropipette. Consequently, it is suggested that a more general nonlinear dynamic model should include the dynamic coupling effects of mercury due to its motion within the micropipette, as it vibrates longitudinally.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
