Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

fundA Canadian funder is recorded on the work.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Mesenchymal stem cells (MSC) may differentiate into adipocytes, osteoblasts or chondrocytes, the latter leading to hypertrophic chondrocytes responsible for endochondral ossification. The presence of the transcription factor cbfa1 is a prerequisite for osteoblast development, but is also of major importance in chondrocyte transition to the hypertrophic state. For cartilage tissue engineering, we need to prevent hypertrophic phenotype of MSC differentiated to chondrocytes. For this, we transfected mesenchymal stem cells transiently with anti-cbfa1 siRNA and investigated its effect on bone morphogenic protein (BMP)-2-induced osteogenesis in monolayer culture, or chondrogenesis in cultured micropellets.

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.
