Abstract

fetched live from OpenAlex

This article is a commentary on the recently published manuscript by Drey et al. (2014). The age-related loss of motor units (MU) is an immutable process and understanding the possible role of physical activity in maintaining functional MUs is an important topic. Dysfunctional remodelling of a MU is associated with denervation of the muscle and ultimate death of the spinal motoneurone. Conversely, in cross-sectional studies, high levels of physical activity in humans report a maintenance in the number of functional MUs in older master runners. However, it seems that only those MUs directly associated with the elevated long-term physical activity appear to benefit from any exercise-induced neuroprotective effect.

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.
