An experimental study of middle-ear vibration in rats /
Bibliographic record
Abstract
Animal models are valuable tools in auditory research. Rats are potentially very useful for this purpose. They are low in cost, they are genetically similar to humans, and the middle-ear structures are easily approachable. The goal of the present study is to better characterize the mechanics of the rat middle ear by measuring frequency responses at multiple points on the tympanic membrane for the first time, and with better frequency resolution than in previous studies. A laser Doppler vibrometer was used to measure the vibrations. Measurements were done on seven rats. Tympanic membrane vibrations at seven different points, in the frequency range of 1 000 to 10 000 Hz, are presented. We provide a measure of the noise floor and investigate the linearity of the rat tympanic membrane. The repeatability of the rat's middle-ear response and inter-animal variability at the umbo are presented. The vibration modes of the tympanic membrane and manubrium are also investigated.

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.
