Back Cover: Sex Hormones Function as Sex Attractant Pheromones in House Mice and Brown Rats (ChemBioChem 14/2017)
Bibliographic record
Abstract
The back cover picture shows a female house mouse sensing sex attractant pheromone components [optical isomers of 3,4-dehydro-exo-brevicomin (DEB), (S)-2-(sec-butyl)-4,5-dihydrothiazole (DHT), testosterone] emanating from the urine marking of a male house mouse. Testosterone was well known to control the expression of sexual characteristics and bodily functions of mammals. Here we show that it also elicits attraction behavior in female mice. When we added synthetic testosterone to trap boxes that had already been baited with synthetic DEB and DHT; it increased the capture of adult female mice 15-fold. We predict that testosterone will function as a sex attractant pheromone in diverse taxa. Photo: S.T. More information can be found in the communication by G. Gries et al. on page 1391 in Issue 14, 2017 (DOI: 10.1002/cbic.201700224).

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
