Abstract

fetched live from OpenAlex

The original version of this Article contained errors in Figure 3, where the colors representing “Flight” and “Ground” were swapped. “Flight” was erroneously identified as the green columns, and “Ground” was erroneously identified as the blue columns. The original Fig. 3 appears below. Fig. 3 Viability and programmed cell death (PCD) of Chlamydomonas in flight vs. ground. Aliquots of flown and ground control Chlamydomonas were stained with Annexin V, to identify PCD, and propidium iodide, to identify dead cells, and analyzed by flow cytometry. Values shown are the % positively staining cells and are the mean ± SEM of six replicates. The p values for significance were evaluated by unpaired two-tailed t-test. Full size image

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.
