Abstract
Stroke is considered the second leading cause of death globally.The primary risk factor for stroke-related diseases is high blood pressure, which occurs as a result of insufficient blood transport to the brain due to blockages or ruptures in the blood vessels.This study presents the explicit finite-difference method through discretization of the solution domain of the 1-D Navier-Stokes equations capable of predicting pressure and flow profiles by characterizing key parameters of pressure variations inherent in the human cranial arteries.Interestingly, the results obtained shows that, the part of the wave with higher pressure travels faster to the periphery than the part with lower pressure.The increase in diastolic and a null decrease in systolic pressure as seen in our simulations is as a result of a slower heart rate, since the heart is taking longer time to complete a beat.Our findings shows that a decrease in the radius of the cranial artery from (0.29 -0.275) will result in the increase in pressure within the range (115 -145).

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
