Abstract

fetched live from OpenAlex

The inner nuclear membrane (INM) can receive lipids by lateral diffusion from the outer nuclear membrane and endoplasmic reticulum (ER) at nuclear pores contacts. However, the INM and nucleoplasm also harbour phospholipid and triacylglycerol (TAG) biosynthetic enzymes, and assemble nuclear lipid droplets (nLDs) and lipid-associated PML structures (LAPS) from excess fatty acids. The CDP-choline pathway for synthesis of phosphatidylcholine, a major component of membranes and the surface monolayer of lipid droplets, terminates in the ER and Golgi apparatus but is regulated in the nucleus by the rate-limiting enzyme CTP:phosphocholine cytidylyltransferase α (CCTα).

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.
