Abstract

fetched live from OpenAlex

Mice lacking cryptochromes (mCry1/mCry2-/-) were kept in a 16h light, 8h dark, light-dark (16:8 LD) cycle and were given additional pulses of light of different brightness, starting 2h after dark onset and lasting for 1h. The suppression of wheel running during these light pulses (i.e., masking) was compared to that of wild types. No evidence of any decrement in the masking response to light was detected. As well as studying masking, minor bouts of activity occurring in the main light portion of a light-dark cycle were quantified. One possible explanation of such predark activity is that some damped endogenous process is spared in mCry1/mCry2 double-knockout mice.

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.
