Investigating Gastroesophageal Motility: Mechanical Work done during Esophageal Contractility and Fully Resolved Multiphysics Modeling of Gastric Peristalsis

Description:

Normal gastroesophageal motilty is important to live a comfortable and healthy life. Motility disorders result in impaired transport of ingested food which can lead to extreme discomfort and severe damage to the walls of the esophagus. Significant work has been done to study gastroesophageal motility using advanced diagnostic tools such...

Computational investigation of the neuromechanical problem for swimming

Description:

In fish, caudally propagating waves of neural activity produce muscle bending moments. These moments, coupled with forces due to the body's elastic properties and forces due to fluid-body interactions, determine the deformation kinematics for swimming. Fully resolved simulations of neurally-activated swimming can be used to decode activation patterns underlying observed...
