Abstract

fetched live from OpenAlex

Digested energy, metabolizable energy, digestibility and assimilation rate were quantified at different photoperiods in Niviventer confucianus using the food balance method. Three photoperiods were applied: a short photoperiod (8L∶16D), normal photoperiod(12L∶12D) and a long photoperiod(16L∶8D). The results show that digestibility and assimilation rate were highest in the short photoperiod with values of 83 97%±1 16% and 80 46%±1 34%, and lowest in the normal photoperiod with values of 81 74%±1 76% and 78 45%±1 41%. Moreover, the energy intake, digestibility and assimilated energy of N. confucianus decreased with the amount of daylight. The statistical significance of the results obtained by a one-factor analysis of variance were all less than 0 01 or 0 05 except for digested energy. This indicates that photoperiod is an important environmental factor to affect the energy metabolism of Niviventer confucianus .

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
