Abstract
Addresses the problem of determining whether a transistor circuit possesses multiple dc operating points. We investigate how the sign change of the determinant corresponding to the Jacobian matrix associated with circuit equations can be used to indicate the number of dc operating points in a transistor circuit. We give circuit examples that illustrate that these criteria may not be reliable, and show that resistor values that determine the number of a circuit's dc operating points, may or may not affect the value of the calculated determinant. Even if the mere existence of a feedback structure depends on whether a particular resistor is open- or short-circuited, the resistor value may not affect the value of the determinant. Hence, the determinant criteria is not always indicative of the number of a circuit's dc operating points.

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
