Retinal photoreceptor fine structure in the mallard duck (Anas platyrhinchos)
Bibliographic record
Abstract
The retinal photoreceptors of the mallard \nduck (Anas platyrhynchos) consist of rods, single cones \nand double (unequal) cones present in a ratio of about \n1:2:1. The rods have relatively large cylindrical outer \nsegments which in the light-adapted state reach to the \nretinal epithelial (RPE) cell bodies and are surrounded \nby the pigment-laden apical processes of these RPE cells. \nThe inner segment displays an apically located ellipsoid \nof mitochondria and plentiful polysomes, some rough \nER and Golgi zones. The rod nucleus is located within \nthe outer nuclear layer and the synaptic pedicle displays \nboth invaginated (ribbon) and superficial (conventional) \nsynaptic sites. Single cones display a thin tapering outer \nsegment, a large often heterogeneous oil droplet in the \napical region of the inner segment, an ellipsoid of \nmitochondria and a prorninent paraboloid of glycogen. \nDouble cones consist of a larger chief member which \nshows a thin tapering outer segment, a large heterogeneous \noil droplet and a prominent paraboloid. The small \naccessory cone shows a thin outer segrnent, a small \ngranular oil droplet and a paraboloid. As in the single \ncone, polysomes, RER and Golgi zones are also present \nwithin the inner segment. Near the outer limiting \nmembrane the two members of the double cone show a \nmembrane specialization on their contiguous surfaces. \nBoth single and double cones display severa1 invaginated \n(ribbon) synapses as well as numerous superficial \nsynaptic sites

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
