A Man for All Seasons: Celebrating the Scientific Career of Yves Clermont
Bibliographic record
Abstract
Over the span of more than 50 years, Yves Clermont (Fig. 1) made a series of transformative contributions that laid the foundation for all modern studies on spermatogenesis. He discovered that there is a pattern of organization of germ cells in seminiferous tubules, and he identified the stages of progression of germ cells from spermatogonia to spermatozoa as well as the kinetics of spermatogenesis in many species, including humans. His precise descriptions of most germ cell organelles and their transformation during spermatogenesis remain the standard works of reference. In the course of his studies, he helped establish the field of stem cell biology by examining how spermatogonial stem cells can both renew themselves and produce very large numbers of spermatozoa. His research accomplishments are matched only by his extraordinary communication skills, having been awarded every teaching award at his institution, McGill University. ... In 1950, a young Yves Clermont joined the team of Charles P. Leblond, who became his thesis supervisor. Clermont accepted the difficult challenge of making sense of the cell associations found in the seminiferous epithelium of three different species. He successfully responded to the gauntlet laid down by Leblond and in the next three years managed to complete his Ph.D. thesis [1]. These studies constituted the foundation of the modern understanding of spermatogenesis and of the spatial and temporal organization of the seminiferous epithelium. Since that time, Clermont and his trainees have continually made insightful contributions regarding complementary aspects of the structure and functions of the seminiferous epithelium; spermatogonial renewal in rodents, primates, and humans; structure and functions of germ and Sertoli cell organelles and cytoskeleton; and hormonal control of spermatogenesis.

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.
