Abstract

fetched live from OpenAlex

The effects of meso-scale wind speed fluctuations associated with IGWs on the statistical characteristics of the parameters of the acoustic pulses in stable ABL were studied. An acoustic pulse sounding method based on the existence existence of an acoustic wave guide near ground surface was used to measure meso-scale wind speed and temperature fluctuations. It was observed that the acoustic pulses of stable form were generated due to detonation ofthe air-propane mixture with the repetition period of 30 seconds. It was also observed that the sum of phase differences was close to zero within a frequency interval and this fact indicated a wave like character of the observed low-frequency fluctuations.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
