Abstract

fetched live from OpenAlex

> Le plan d'organisation du corps des vertébrés est métamérique dans le sens antéro-postérieur.Les structures périodiques dans l'espace, dont les somites, précurseurs des vertèbres elles-mêmes, se forment dans la continuité de la gastrulation lors de l'élongation de l'axe antéro-postérieur.La régularité et la flexibilité de ce processus ont amené Cooke et Zeeman en 1976 à postuler l'existence d'une horloge de segmentation moléculaire, rythmant la formation des somites au cours du développement, et d'un front d'interaction se déplaçant vers le pôle postérieur [1].Le rôle de ce front dynamique serait d'interagir avec l'oscillation de segmentation temporelle afin de former les motifs périodiques spatiaux.Il a fallu attendre 1997 pour que cette hypothèse théorique soit confirmée en partie, avec la mise en évidence, dans le mésoderme présomitique, d'oscillations de la concentration du produit du gène c-hairy chez le poulet [2].De nombreux travaux ont depuis confirmé l'existence d'oscillations d'expressions génétiques lors de ce processus, et ce dans au moins trois voies de signalisation (Notch, FGF, Wnt) ; des développements technologiques très récents permettent de les visualiser en temps réel [3-5] (➜).Cependant, la dynamique des oscillations elles-mêmes, ainsi que celle de l'hypothétique front de différenciation restent mal comprises.

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.
