A Backwards-Tracking Lagrangian-Eulerian Method for Viscoelastic Two-Fluid Flows

Applied Sciences, 2021
A new Lagrangian–Eulerian method for the simulation of viscoelastic free surface flow is proposed. The approach is developed from a method in which the constitutive equation for viscoelastic stress is solved at Lagrangian nodes, which are convected by ...

No difference in extra-axial cerebrospinal fluid volumes across neurodevelopmental and psychiatric conditions in later childhood and adolescence

Journal of Neurodevelopmental Disorders, 2023
Background While autism spectrum disorder has been associated with various organizational and developmental aberrations in the brain, an increase in extra-axial cerebrospinal fluid volume has recently garnered attention. A series of studies indicate that

Assessing volume status and fluid responsiveness in the emergency department [PDF]

Clinical and Experimental Emergency Medicine, 2014
Resuscitation with intravenous fluid can restore intravascular volume and improve stroke volume. However, in unstable patients, approximately 50% of fluid boluses fail to improve cardiac output as intended.

A Machine Learning Approach to Volume Tracking in Multiphase Flow Simulations

Fluids
This work presents a machine learning (ML) approach to volume-tracking for computational simulations of multiphase flow. It is an alternative to a commonly used procedure in the volume-of-fluid (VOF) method for volume tracking, in which the phase ...
