Abstract

fetched live from OpenAlex

Abstract Platelets are blood cells that initiate the hemostatic plug that causes blood clot formation. Patients receiving intense chemotherapy or suffering massive bleeding complications require platelet transfusions for the prevention of a potentially fatal hemorrhage. A stable, readily available inventory of platelets is required for the safe and effective delivery of health care. Since platelets must be kept warm to remain viable, they are subject to bacterial contamination, and thus have a shelf life of between five and seven days. Since platelets have a very limited shelf life and are expensive to collect and produce, outdates are an important practical concern for hospitals and blood system operators. Thus, the platelet inventory problem revolves around identifying policies for ordering and holding platelets such that unit availability is maximized, while ensuring that outdates are minimized. In this paper we define the platelet inventory problem, survey the existing literature, and provide a discussion of solution approaches.

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.
