Abstract

fetched live from OpenAlex

This paper describes the results of a simulation of blood flow and myocardium motion in an average canine left ventricle (LV) with fluid-structure interaction. The computed LV cavity pressure was in fair agreement with previous measurements over most of the cardiac cycle; however, during rapid filling, the calculated pressure was lower than the measured one, which led to non-physiological backflow. Trends of LV cavity volume changes were nearly physiological for three of the four phases of the cardiac cycle but the ejection fraction was lower than physiological. This method predicts appreciable pressure variations in the LV cavity, in contrast to solid-only simulations which assume uniform cavity pressure. The dependence of the results on various model parameters is briefly discussed along with suggestions for future work.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
