Abstract

fetched live from OpenAlex

Despite being poikilothermic organisms, ticks are known to inhabit northern regions with temperatures that annually drop below freezing during the winter months. Former research has been conducted on a variety of tick species to assess the limits of their cold tolerance and the mechanisms they use to live in such challenging temperature conditions. A proposed mechanism that aids the tick in cold tolerance is by synthesizing antifreeze proteins (AFPs) in the tick’s fluids; AFPs work by binding to formed ice crystals and preventing further growth.  Previously, an antifreeze glycoprotein was identified in Ixodes scapularis, and its presence increased cold tolerance in the tick species. This study aims to assess the survival limits of both Dermacentor variabilis and Dermacentor andersoni in challenging cold temperatures, and to monitor changes in AFP gene expression over time when ticks are exposed to cold temperature conditions.   Faculty Mentor: Kevin Friesen Department: Biological Science (Honours)

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
