Abstract
BACKGROUND: Infantile hemangiomas (IHs) are benign vascular neoplasms with rapid capillary proliferation shortly after birth and slow involution with diminishing capillary proliferative activity, fibrosis, and fatty replacement over 7-10 years. METHODS: Hemangiomas and contralateral control sites in 88 subjects were measured using a suction device, 6-mm probe and 200 mbar negative pressure. Mechanical properties were assessed vs. controls and effects of body site, depth, clinical stage, histology diagnosis, and time. RESULTS: Biological elasticity, overall elasticity, net elasticity, total recovery, and elastic recovery were lower for IH vs. controls (P < 0.001). IH total deformation, elastic deformation, viscoelastic creep, and residual deformation were higher than controls (P < 0.001). Involuting IHs had lower viscoelasticity than proliferating and stable lesions (P < 0.001) and lower viscoelastic creep than stable IHs (P = 0.04). IH viscoelasticity was higher at 2.3 than 12.9, 23.7, and 61.0 months and at 4.9 and 8.1 than 61.0 months. IH elastic recovery varied by body site with larger differences vs. control for abdomen and leg. Elastic recovery differences from control were smaller at younger vs. older ages. CONCLUSIONS: Measurement of biomechanical properties may be useful to characterize IH progression and treatment response in clinical settings.

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 it
