Circumferential Variation of Mechanical Properties of Ascending Aorta (AA): A Comparative Study of Healthy and Dilated AA
Bibliographic record
Abstract
The biomechanics within the ascending aorta (AA) characterizes the pressure and flow for the entire vascular system. In the aortic wall, it is the structured medial layer that is responsible for the mechanical properties of the AA. The mechanical properties are determined to a large extent by the composition of elastin, collagen and smooth muscle cells (SMCs). Changes in AA biomechanics that arise with age and/or disease can lead to cardiovascular complications and death. Most studies that have investigated the biomechanics of these diseases have assumed homogeneous and isotropic aortic wall properties. Very little work has been done in vitro to determine the local mechanical properties of human vascular tissue. In order to better understand the biomechanics of the human AA, the local properties of pathologic AA tissue from both tricuspid and bicuspid aortic valve patients have been studied and compared with the properties of healthy aortas.

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.
