Abstract

fetched live from OpenAlex

A shared variable is an abstraction of persistent interprocess communication. Processors execute operations, often concurrently, on shared variables to exchange information among themselves. The behavior of operation executions is required to be “consistent” for effective interprocess communication. Consequently, a consistency specification of a shared variable describes some guarantees on the behavior of the operation executions. A Read/Write shared variable has two operations: a Write stores a specified value in the variable and a Read returns a value from the variable. For Read/Write variables, a consistency specification describes what values Reads may return. Using an intuitive notion of illegality of Reads, we propose a framework that facilitates specifying a large variety of Read/Write variables.

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.
