Abstract
A technique of interaction of computer programs for symbolic analysis of complex electronic circuits with amplifying elements is proposed. FASTMEAN simulation program, used in the universities of telecommunications in Russia, has a symbolic analysis module and is capable of generating analytical expressions for Laplace images of a circuit determinant, currents and voltages in complex electronic circuits. However, the obtained expressions have a nested (folded) structure, which makes it difficult to analyze the influence of elements on the properties of a circuit with amplifiers and feedbacks, in particular on its stability. It is proposed to transfer the obtained expressions to Maplе program for their structural transformation and mathematical processing. . Amplifiers with local, common and crossed feedbacks are considered. The analysis of such circuits in Maple shows that an expression for the circuit determinant in the form of the products of the loop gain functions is a sign of the presence of several feedback loops in the circuit.

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
