Effect of hyperbaric pressure and temperature on respiration rates and quality attributes of <scp>B</scp>oston lettuce
Bibliographic record
Abstract
Summary A study was conducted to determine whether hyperbaric treatment has an effect on the shelf life of lettuce during short‐term storage. Lettuce was treated with different pressure and temperature conditions (100–850 kPa at 20 °C and 100 kPa at 4 °C). A preliminary experiment was performed with different treatment periods, that is, 3, 5 and 7 days. Hyperbaric treatment of lettuces at 20 °C caused noticeable changes in sensory quality, but the product was still marketable after 3 days. On the other hand, the cold‐stored lettuce showed little degradation even after 7 days of treatment, at which time all the lettuce treated at 20 °C was unmarketable. At 5 days of treatment, the respiration rate of hyperbaric‐treated lettuces at 625 and 850 kPa remained fairly stable, while that of the lower‐pressure‐treated lettuce began to increase, indicating the initiation of decay. The 850‐kPa hyperbaric treatment showed better quality results than the 100 kPa, 20 °C treatment. Overall, hyperbaric treatment has the potential of being used as an alternative technique for short‐term storage of lettuce without refrigeration.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
