Abstract
This paper presents an active mechanical perforation method developed for embryo biopsy in the preimplantation genetic diagnosis (PGD) procedure. This mechanical approach utilizes a tungsten micro-needle with a sub-micrometer tip to perform embryo perforation. The micro-needle is driven longitudinally with sinusoidal or square wave signals at frequencies close to the micro-needle bending resonances in order to excite its lateral vibration modes due to nonlinear modal coupling. It has been demonstrated that, in particular, the lateral cutting method, is effective and suitable for embryo perforation as well as microinjection and micro-dissection. A micro-needle driven with a square wave signal at frequency (~850Hz) close to the micro-needle first bending resonance frequency has been shown to generate an accurate cutting dimensions with minimum damage to the mouse embryo zona pellucida. A success rate of 88 % was achieved based on eight perforation tasks.

How this classification was reachedexpand
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.
