Abstract

fetched live from OpenAlex

Explosions account for the majority of wounds sustained by soldiers on the battlefield.Due to difficult human factors and ergonomics, areas often left unarmoured are the extremities.Injuries to these areas accounted for approximately half of the total injuries sustained by coalition forces in Iraq and Afghanistan.Buried charges I owe many thanks to those who have supported me throughout my research.Thank you to my supervisor, Professor Oren Petel, for first allowing me to take your graduate course during my undergrad and for introducing me to this field.His guidance and support in the last three years has made me more knowledgeable, a better researcher and has brought me closer to being an excellent engineer.I am grateful for the opportunity to learn from him and to have overcome the many challenges presented along the way -it has truly been a wonderful experience.Throughout my time at Carleton University, I have had the pleasure of meeting a number of amazing people.I would like

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.
