Abstract

fetched live from OpenAlex

The system structure and the lidar principle of a mobile differential absorption lidar(DIAL) system designed by ourselves were described.The operation wavelengths of a tunable laser for SO_2 measurement were 286.3 nm and 286.9 nm and the measurement range is approximately from 500 m to 3 km.The field tests in Beijing and Hefei were performed with the lidar system.Examples of measurements of sulfur dioxide in Hefei and Beijing are given and results agree with the measurement results of ground monitor instrument.The error scope is analyzed and the total measurement error is 7 10~(-9) with range resolution of 300 m.

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.

Not 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.
