A novel roller pump for physiological flow [PDF]
AbstractHaving physiological correct flow waveforms is a key feature for experimental studies of blood flow, especially in the process of developing and testing a new medical device such as stent, mechanical heart valve, or any implantable medical device that involves circulation of blood through the device.

Physiologic blood flow is turbulent [PDF]
AbstractContemporary paradigm of peripheral and intracranial vascular hemodynamics considers physiologic blood flow to be laminar. Transition to turbulence is considered as a driving factor for numerous diseases such as atherosclerosis, stenosis and aneurysm.

Physiological non-Newtonian blood flow through single stenosed artery [PDF]
A numerical simulation to investigate the Non-Newtonian modeling effects on physiological flows in a three dimensional idealized artery with a single stenosis of 85% severity is given. The wall vessel is considered to be rigid.

Physiologic Data-Driven Iterative Learning Control for Left Ventricular Assist Devices
Continuous flow ventricular assist devices (cfVADs) constitute a viable and increasingly used therapy for end-stage heart failure patients. However, they are still operating at a fixed-speed mode that precludes physiological cfVAD response and it is ...

We examined the relation between psychological flow and cardiovascular markers of challenge. According to flow theory and the biopsychosocial model of challenge and threat (BPS-CT) optimal motivational states (flow, challenge) arise during activities where task demands meet personal resources. Participants (N = 154) played Tetris in either an underload,
