Pressure -- area loop based phenotypic classification and mechanics of esophagogastric junction physiology
Guy Elisha, Sourav Halder, Shashank Acharya +5
The esophagogastric junction (EGJ) is located at the distal end of the esophagus and acts as a valve allowing swallowed materials to enter the stomach and preventing acid reflux. I…
Peristaltic regimes in esophageal transport
Guy Elisha, Shashank Acharya, Sourav Halder +5
A FLIP device gives cross-sectional area along the length of the esophagus and one pressure measurement, both as a function of time. Deducing mechanical properties of the esophagus…
Esophageal virtual disease landscape using mechanics-informed machine learning
Sourav Halder, Jun Yamasaki, Shashank Acharya +6
The pathogenesis of esophageal disorders is related to the esophageal wall mechanics. Therefore, to understand the underlying fundamental mechanisms behind various esophageal disor…
A Fully Resolved Multiphysics Model of Gastric Peristalsis and Bolus Emptying in the Upper Gastrointestinal Tract
Shashank Acharya, Sourav Halder, Wenjun Kou +3
Over the past few decades, in silico modeling of organ systems has significantly furthered our understanding of their physiology and biomechanical function. In this work, we presen…
Mechanics Informed Fluoroscopy of Esophageal Transport
Sourav Halder, Shashank Acharya, Wenjun Kou +3
Fluoroscopy is a radiographic procedure for evaluating esophageal disorders such as achalasia, dysphasia and gastroesophageal reflux disease (GERD). It performs dynamic imaging of…
Pumping Patterns and Work Done during Peristalsis in Finite-length Elastic Tubes
Shashank Acharya, Wenjun Kou, Sourav Halder +4
Balloon dilation catheters are often used to quantify the physiological state of peristaltic activity in tubular organs and comment on their ability to propel fluid which is import…
