Abstract

fetched live from OpenAlex

Most electron microscopy studies of Mycobacterium tuberculosis ultrastructure were performed in the 1950s and 1960s and lack high resolution by modern standards. This study was performed to re-evaluate the fine structure of M. tuberculosis using modern scanning electron microscopy. Bacteria were grown in rich medium with a constant supply of oxygen for several weeks. Results show that surface bleb-like structures accumulate as cultures age. The most unusual feature of aging M. tuberculosis cultures is that they develop extracellular fibrils, which could play roles of adhering cells to surfaces and to one another.

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.
