Abstract

fetched live from OpenAlex

Sea urchin skeletons (tests) exhibit pentamerous symmetry, a pattern that emerges from the beautiful and intricate arrangements among the plates of which they are composed. Plate patterns and test shapes have proven difficult to explain and describe solely on the basis of any one process. Using theoretical morphology, the discipline that involves using mathematical modelling and computer simulation to describe growth and form, we introduce a new computational model that utilises the manner with which soap bubbles interact in close-packing formation to emulate plate addition, shift, gapping and growth. The computational model is governed by close-packing configuration (Descartes circle theorem) and soap bubble interactions (Plateau's Laws). Through this analogy, our computational model can be used to describe the evolutionary morphological changes observed in sea urchin skeletons.

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.
