Abstract

fetched live from OpenAlex

Hibernation is a fascinating survival adaptation that allows animals to transition into a torpid state to survive the winter by coordinating a strong suppression of metabolic rate, conservation of fuel/energy, and reduction of body temperature.This strategy permits thirteen-lined ground squirrels (Ictidomys tridecemlineatus) and other hibernating mammals to endure the harsh winter season when there is little access to food.Many energy-expensive cellular processes are suppressed, including gene transcription and protein synthesis/turnover, but are reactivated rapidly when animals arouse back to euthermia.Both torpor and arousal can have damaging consequences; for example, during arousal, reactive oxygen species flood the cell causing oxidative damage to numerous cellular components.Therefore, hibernation requires many pro-survival mechanisms to mitigate multiple types of damage: e.g. from oxidative damage, DNA damage, and pathogen attack, among others.The research reported in this thesis on damage control processes in hibernators shows that antioxidant enzymes such as PRDXs are upregulated in key tissues but in an isoform-specific and time-specific manner over the torpor-arousal

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.
