Abstract
A photothermal technique for ultra-high resolution measurements of thermal diffusivity of liquid mixtures was developed. Frequency scan experiments using the thermal-wave resonator cavity (TWRC) method [1] were performed. A theoretical model describing the one-dimensional temperature field within the cavity was developed. Comparison between the theoretical and experimental data for signal amplitude and phase in water shows excellent agreement. To achieve the ultra-high sensitivity of the measurements for liquid mixtures at low concentrations we modified the thermal-wave resonator cavity method coupling it with a signal common-mode rejection demodulation (CMRD) scheme [2]. This non-conventional technique has shown sensitivity of the photothermal signal to methanol in water at the level of 0.25% by volume.

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
