Ultrasonic characteristics for gel formation in the California mastitis test
Bibliographic record
Abstract
Mastitis is one of the most serious and costly diseases affecting dairy cow production. Measurement of the somatic cell count (SCC) in raw milk is widely accepted as the most useful indirect indicator of mastitis and milk quality. Fast analysis devices, or systems would be highly desirable as they would allow an on-line response to the changes in media components. However, most on-line systems currently used have a low accuracy. The rheology of the gel formed in the CMT was investigated by using both capillary and rotational viscometry and found that the gel is non-Newtonian, but the initial phase of viscosity increase was not due to shear dependence, but rather due to the gelation reaction. Results also demonstrate that attenuation increases with mixing duration, probably due to the friction of ultrasound propagated in gelation obviously affected by the gel viscosity, which may tend some ultrasonic energy to be adsorbed and tuned into heat.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
