Abstract
Atherosclerosis is hardening and narrowing of arteries due to deposition of fatty materials (plaque) at the inner walls and it is known that haemodynamic plays a major role in the development of such disease. Present work considers non-Newtonian behaviour and pulsatile nature of blood flow in the three-dimensional numerical computations using Ansys Fluent 14.0. Majority of blockages in arteries have been generally reported to be asymmetric and it is observed that it has different flow dynamics than symmetric constrictions. Accordingly, effect of severity (40% and 60%) and asymmetry in constriction on possible plaque formation and flow dynamics has been predicted using oscillatory shear index (OSI). The flow field characteristics and OSI variation reveal that an existing occlusion may evolve into multiple occlusions through complex flow behaviour.

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
