Abstract

fetched live from OpenAlex

Pressure changes caused by an ultrasound pattern inside tissue will modify its density and hence its refractive index. We present an integrated computational imaging approach to minimize multiple-scattered reflected light from tissue. It is based on optimum modulation of the refractive index of tissue using an ultrasound pattern. We examine issues related the design of such pattern using COMSOL Multiphysics. An optimum ultrasound pattern could be used to design and implement an integrated- computational optical coherence tomography (IC-OCT) system with extended depth of imaging.

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.
