Abstract

fetched live from OpenAlex

Abstract Evapotranspiration (ET) is the transfer of water vapor from the soil root zone to the atmosphere via the process of photosynthesis. Water vapor can also move directly from the ground surface to the atmosphere. The rate of ET depends on several climatic, soil water, and crop factors, including rainfall, relative humidity, wind speed, air temperature, solar radiation, cloud cover, soil moisture, and stage of crop growth. The plant transpires at the potential rate if soil water is not limiting, which depends on the soil water content. Water is held in the soil root zone in three distinct phases: hygroscopic water, capillary water, and gravitational water. Because of the high tension of the hydroscopic water, it is not available to plants. Both capillary water and gravitational water are available for crop uptake in the ET process.

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.

Full frame distilled prediction

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.
