Abstract

fetched live from OpenAlex

Biological tissues are a combination of cellular and acellular components.The extracellular matrix (ECM), or the acellular component of tissues, is often overlooked.Tracking changes in the ECM grants insight into how aging, diseases and treatments might affect tissue structures and cellular responses.Using gray-level texture analysis, we analyzed the architecture of fibrillar collagen, a major component of the ECM.Several gray-level textural features were extracted from second harmonic generation (SHG) images and used to characterize collagen network arrangements.This work provides a basis for a classification model aimed to track changes in the cellular microenvironment.This information is vital if we wish to continue exploration of how diseases develop in different tissues, and develop novel and effective treatments for different types of chronic diseases.

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.
