Abstract
This paper presents a novel approach to in-line chemical gas flow monitoring, employing a high-Q RF resonator coated with a polymeric sensing material. The polymeric sensing materials employed are OV-275 and P25DMA doped with 20% NiO. These materials are known to be responsive against various VCOs, and are individually coated on the post of a combline cavity resonator to help functionalize the sensor against specific analytes. The input of the resonator was deliberately designed to achieve the minimal loading to maximize the loaded Q of the resonator, thereby improving its sensitivity near its f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> . The OV-275 sensor demonstrates sensitivity of 2.332 mdB/ppm and 0.348 mdB/ppm to acetone and benzene exposure, respectively. Similarly, the P25DMA sensor has a sensitivity of 0.199 mdB/ppm and 0.764 mdB/ppm to acetone and benzene, respectively.

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
