Abstract

fetched live from OpenAlex

The purpose of this study was to examine patterns of energy of reflectance (ER) in preoperative and post-operative conditions in otosclerotic ears. It was also within the scope of this paper to investigate whether the changes in ER pattern post-operatively correlate to the improvement in hearing as measured by pure-tone audiometry. ER was measured in 15 surgically confirmed otosclerotic ears (mean age: 44 years) before and after the stapes surgery. The most prominent change in ER pattern following the surgery in majority of the subjects was a sharp and deep drop in ER value between 700-1000 Hz. There was also a secondary wider and smaller increase in ER value following the surgery between 2000-4000 Hz. Moreover, in most cases the drop in ER values following the surgery at low frequencies (<or=1000 Hz) approximated the mean ER values in the normal group. Comparison of ER patterns with hearing improvement as measured by air conduction averaged across low (250-1000 Hz) and high (2000-6000 Hz) frequency bands before and after the surgery did not reveal any significant correlation. However, there was a general positive correlation trend for ER changes in low frequency band and AC changes, especially for high frequency bands. Changes in ER pattern may potentially be useful as an objective tool for monitoring the impact of the stapes reconstructive surgery and evaluating different surgical protocol.

Teacher imitation

Not 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.
