BLOOD FLOW IN THE CIRCLE OF WILLIS: MODELING AND CALIBRATION

MULTISCALE MODELING & SIMULATION, 7(2), 888–909.

By: K. Devault n, P. Gremaud*, V. Novak*, M. Olufsen*, G. Vernieres & P. Zhao

author keywords: blood flow; viscoelastic arteries; fluid-structure interaction; Kalman filtering
TL;DR: A numerical model based on one-dimensional balance laws and ad hoc zero-dimensional boundary conditions is tested against experimental data and demonstrates the viability of the proposed approach on the circle of Willis, a vital subnetwork of the cerebral vasculature. (via Semantic Scholar)

Modeling heart rate regulation - Part I: Sit-to-stand versus head-up tilt

CARDIOVASCULAR ENGINEERING, 8(2), 73–87.

By: M. Olufsen n, A. Alston n, H. Tran n , J. Ottesen & V. Novak*

author keywords: mathematical modeling; heart rate regulation; sensitivity analysis
MeSH headings : Aged; Baroreflex / physiology; Blood Pressure / physiology; Computer Simulation; Feedback, Physiological / physiology; Female; Head / physiology; Heart Rate / physiology; Humans; Male; Models, Cardiovascular; Posture / physiology; Tilt-Table Test / methods
TL;DR: During head-up tilt, the baseline firing-rate is larger than during sit-to-stand and that the combined effect of vestibular and central command stimulation of muscle sympathetic nerve activity is less pronounced than during sitting to standing. (via Semantic Scholar)
