摘要:
The functioning of mammalian bodies requires many repetitive processes involving fluids, like coughing, blinking, walking and running. The most representative of these processes is the heartbeat, which makes blood flow in the arterial system at the
frequency imposed by the heart. In this talk, we address the question of what determines the specific rates at which mammalian hearts beat. We introduce the concept of dynamic permeability, which contains information about the fluid and the confinement. It tells us how the fluid responds to each of the frequencies involved in the pressure gradient. For networks, this concept can be generalized to a dynamic response whose maxima give the frequencies at which the fluid flows with the least possible resistance. We compare our model predictions with the heart rates of 100 mammals ranging from ferrets to African elephants and conclude that our model offers a plausible physical explanation of mammalian heart rates.
报告人简介:
Eugenia Corvera Poiré is a full professor at the Faculty of Chemistry, Universidad Nacional Autónoma de México (UNAM). She earned her Bachelor's in Physics from Universidad Autónoma Metropolitana (Mexico City) and later completed her Master's and PhD in Physics at McGill University in Montreal, Canada. She conducted postdoctoral research in complex fluids at the University of Pittsburgh and École Normale Supérieure in Paris.
Eugenia holds the highest rank at both UNAM and Mexico's National Research System. In 2021, she received UNAM’s most prestigious award, granted to less than 5% of faculty.
Her research focuses on the dynamics of pulsatile flows, with applications in medicine and microfluidics. She has developed notable models of arterial blood flow and pulsatile flows at microfluidic interfaces, aiming to understand fluid control through externally applied frequencies. Her work has potential applications in increasing flow through membranes, reducing tumor blood supply, and controlling cell stress in organ-on-a-chip devices.
She has established research collaborations with the University of Barcelona, King's College London, and St. Thomas Hospital, using experimental and clinical data to validate her models. Her research has been funded by institutions including the Generalitat de Catalunya, the Spanish Ministry of Education, Conahcyt, DGAPA, and the European Commission. She was also awarded the Marie Curie distinction and has held visiting positions at King’s College London, the University of Sheffield, and the Institute of Complex Systems at the University of Barcelona.
