Using coherent small angle xray scattering to measure velocity fields and random motion
Bibliographic record
Abstract
La dynamique de polymères réticulés de stress, telles que celle qui compose le caoutchouc, n'est pas encore bien comprise. Une combinaison de techniques homodynes et hétérodynes de rayons x coherentes est utilisé pour mesurer les fluctuations du système, une fois étiré. La combinaison des deux techniques permet la mesure des régimes d'écoulement, ainsi que le caractère aléatoire du système. Après l'analyse des données, les résultats montrent que les mesures ont réussi à capturer cet information. La vitesse d'écoulement a été découverte de contenir une nature en fonction du temps semblable à celle de la courbe contrainte-déformation. Après la vitesse d'écoulement a été extraite, la nature aléatoire du système a été analysé. Cette motion a été découverte au hasard de ne pas être dominé par la diffusion classique, mais de certains processus aléatoires plus lents.

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.
