Abstract

fetched live from OpenAlex

Advances in stem cell technology allow the reprogramming of patient-derived cells, obtained from urine samples or skin biopsies, into induced pluripotent stem cells (iPSCs), which can then be differentiated into any cell type. With this goal in mind, we will present how experimental developments, mostly in the field of microfluidics, can be used to extract several relevant spatiotemporal biophysical properties from the quantitative phase signal provided by digital holographic microscopy, thus moving towards the realization of a truly effective optofluidic platform for non-invasive characterization of cell structure and dynamics. Such label-free characterization is highly conducive to the identification of disease-specific cell phenotypes when comparing iPSC-derived cells from control and diseased patients.

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.
