Abstract

fetched live from OpenAlex

Glaciers provide an impressive application of fluid mechanics and materials, and thermal physics. The basic microphysical properties of ice determine the shape of a glacier or ice cap. The order of magnitude of the maximum ice thickness is predicted using Weisskopf’s heuristic argument for the maximum height of a mountain, which involves only the specific latent heat of fusion and the acceleration of gravity. The local thickness of a glacier depends on the assumed ice rheology. The equations describing the steady state longitudinal glacier profile differ greatly for perfectly plastic ice and for ice following Glen’s law. Analytical solutions of these equations are derived: they fit well the data for ice caps but less so for alpine glaciers. Volume-area scaling, a major tool of glaciology, is discussed in relation with glacier profiles.

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.
