Abstract

fetched live from OpenAlex

The blind cave-dwelling fish Phreatichthys andruzzii shows rapid eye development, and at a temperature of 29.5°C, maximal eye differentiation is reached 36 h after egg laying. Very rapid eye degeneration then occurs, and a rudimentary and very degenerated ocular cyst is all that remains 1 month later. This may explain why this species has so often been erroneously considered anophthalmic. Ocular degeneration starts with a decrease in the rate of mitosis in the neuroblastic cells of the retinal Anlage. Degeneration by means of lytic processes is clearly observed beginning 32 h after egg laying. Disappearance of the lens, transformation of the cornea into skin, and cryptic degeneration of the eyes are phenotypic variations of the fundamental mechanisms of eye development in vertebrates. These can be considered evolutionary adaptations by the ancestral fishes to the aphotic cave environment.

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.
