Abstract

fetched live from OpenAlex

The process of re-distribution of black soil in sloping field for about 100 year was studied utilising fly ash and 137Cs trace technique; then the loss amount of soil organic carbon (SOC) was corrected. The upslope site always suffered erosion, while the distribution depth of 137Cs and fly ash reached 30cm and 60cm at foot-slope depositional site and 70cm and 80cm at toe-slope site respectively, explaining that considerable amount of organic carbon was sequestered under the current plowed layer in the depositional area. The depth of fly ash distribution at foot-slope was consistent with the surface of original buried layer, indicating that the study area had been cultivated before the use of steam locomotive. After consideration of solid redistribution accumulating SOC in the depositional area, SOC in the depositional sites became a local sink of atmosphere CO2. The loss amount SOC in the whole study area was lower than the calculation result with traditional method.

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.
