Abstract

fetched live from OpenAlex

Polychromatic digital holographic microscopy (P-DHM) has proven its capacity to provide quasi-coherent noise-free quantitative-phase images, allowing a high-quality visualization of cell structure. In this work we propose a fully automated hologram reconstruction methodology, including a fast-numerical approach for the correction of the defocusing resulting from both the axial chromatic aberrations as well as the fluctuations of the optomechanical elements. This methodology able to reconstruct a large number of holograms paves the way to develop a time-resolved P-DHM capable of non-invasively visualizing both the fine cell structure and dynamics.

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.
