Abstract

fetched live from OpenAlex

When nutrients enter the intestine from the stomach, the movements of the intestine caused by contractions of the intestinal musculature (“intestinal motility”) have to fulfill the function of mixing the content with digestive enzymes and optimizing absorption by exposing all content to the lining of the gut. Intestinal motility is performed by smooth muscle cells and orchestrated by intestinal pacemaker cells and by a nervous system that is unique to the intestine. Movements to promote mixing are called “segmentation”, and movements that propel content along are called “peristalsis”. Peristalsis and segmentation in the human intestine are rhythmic and are governed by pacemaker cells called “interstitial cells of Cajal” or “ICC”. With peristalsis, a network of pace­maker cells generates a wave of electrical activity that propagates into the musculature and deter­mines the rhythm and propagation of contraction, similar to the pacemaker system of the heart. A recent discovery published in Nature Communications revealed that the segmentation motor pat­tern is initiated by certain nutrients that activate a second network of pacemaker cells. This second pacemaker activity is an electrical rhythmic signal that interacts with the first pacemaker activity, modifying it in such a way that the musculature responds with a completely different motility pat­tern; it changes the nature of the contractions from peristalsis to non-propulsive segmentation.

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.
