Abstract

fetched live from OpenAlex

Abstract The SNOLAB laboratory is 2 kilometers undeground in Sudbury, Ontario, Canada. The depth of this location results in a reduction of cosmic-radiation induced muons to the negligible level of one muon per square meter per day. The laboratory maintains cleanliness standards to control the radioactivity from dust falling out of the air, from human activity, and from research equipment brought into the lab. The resulting low-radiation environment enables a variety of research, and SNOLAB is focused on rare-event searches such as dark matter searches and nuclear decay studies. In order to enable and advance these research topics, SNOLAB is conducting research and development into cleanliness, low-level assay, radioactive gasses and cryogenics. SNOLAB collaborates, and competes, with other underground laboratories on these research and development topics, as well as operational topics, to support the global research community.

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.
