Abstract

fetched live from OpenAlex

Traditionally, line scan OCT (LS-OCT) systems use a cylindrical lens to generate a line-shaped beam with Gaussian intensity illumination along the line, which leads to spatially-dependent signal-to-noise ratio (SNR) distribution of the OCT system along the B-scan direction. A novel, Powell lens-based LS-OCT (PL-LS-OCT) system was designed for uniform intensity illumination along the B-scan direction. The PL-LS-OCT can generate images with ~ 2 μm × 1.7 μm (lateral × axial) resolution in free space at image acquisition rate of and 4,500 fps. Images of biological tissues were acquired with the PL-LS-OCT system.

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.
