Abstract

fetched live from OpenAlex

Rumex vesicarius (Ruby dock; subgenus Acetosa, section Vesicarii, family Polygonaceae) shows fascinating ways of controlling and staggering seed germination throughout the year. Seeds within the large inflated fruiting valves (fruits) display variations in their ability to germinate, which are related to the time of the year and depend on the presence of light. Perianth-imposed dormancy appears to undergo one distinct seasonal cycle under laboratory conditions. Our results suggest that germination is best during the autumn and winter months but poor during the rest of the year. In the natural environment (fruits either remain on the soil surface or are buried) dormancy release may be occurring several times during the year under appropriate light, temperature and moisture conditions. Preliminary experiments indicate that the fruiting valves produce chemical substances that inhibit seed germination, and their break down appears to be affected by light.

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.
