Abstract

fetched live from OpenAlex

Single-point imaging techniques are capable of performing 1H and 31P imaging of short T 2 * tissues with a good signal-to-noise ratio (SNR) and free of geometric distortions, making possible MRI of objects with very large susceptibility differences. Centric sampling strategies implemented in the SPRITE (single point ramped imaging with T 1-enhancement) family of sequences lead to significantly reduced acquisition times and facilitate the combination of the imaging sequences with various magnetization preparation schemes. Single-point imaging techniques are slower than frequency-encoding-based methods; however, they can allow the imaging of species with ultrashort T 2 * with good spatial accuracy and well-described signal intensity, thus enabling quantitative analysis.

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.
