Abstract

fetched live from OpenAlex

Mass measurements of $^{68}\mathrm{Ge}$, $^{68}\mathrm{As}$, and $^{68}\mathrm{Se}$ have been obtained with the Canadian Penning Trap mass spectrometer. The results determine the mass excess of $^{68}\mathrm{Se}$ as $\ensuremath{-}54\text{ }232(19)\text{ }\text{ }\mathrm{keV}$, the first measurement with a precision and reliability sufficient to address the light-curve and energy output of x-ray bursts as well as the abundances of the elements synthesized. Under typical conditions used for modeling x-ray bursts, $^{68}\mathrm{Se}$ is found to cause a significant delay in the rp process nucleosynthesis.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
