Abstract

fetched live from OpenAlex

Classification of snow samples based on the thick-section method presents difficulty in recognizing the types of snow having similar structure. Using a double-microtoming technique together with thermal etching, textural details of vertical and horizontal thin sections of different snow samples are obtained. It has allowed us to examine the texture of different types of snow, which was not possible using the thick-section technique. This technique is capable of bringing out the grain or sub-grain boundaries and clearly shows the type of bonds between crystals (geometric or crystalline) using polarized light for relatively large-angle boundaries and thermal etching for small-angle boundaries. This way, one can characterize the texture of various snow types. The texture of snow that has not been studied so far is added information that can further classify a snow sample in addition to the common classes of snow. PACS No.: 92.40Rm

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.
