Linearization of the Navier-Stokes equations [PDF]

E3S Web of Conferences, 2020
This paper studies mathematical models of the heat transfer process of a viscous incompressible fluid. Optimal control methods are used to solve the problem of optimal modeling.

Prediction of fluid responsiveness in mechanically ventilated cardiac surgical patients: the performance of seven different functional hemodynamic parameters

BMC Anesthesiology, 2018
Background Functional hemodynamic parameters such as stroke volume and pulse pressure variation (SVV and PPV) have been shown to be reliable predictors of fluid responsiveness in mechanically ventilated patients.

Dynamic and volumetric variables reliably predict fluid responsiveness in a porcine model with pleural effusion [PDF]

, 2013
Background: The ability of stroke volume variation (SVV), pulse pressure variation (PPV) and global end-diastolic volume (GEDV) for prediction of fluid responsiveness in presence of pleural effusion is unknown.

Fluid intelligence and brain functional organization in aging yoga and meditation practitioners

Frontiers in Aging Neuroscience, 2014
Numerous studies have documented the normal age-related decline of neural structure, function, and cognitive performance. Preliminary evidence suggests that meditation may reduce decline in specific cognitive domains and in brain structure.

Numerical Resolution of Fluid Dynamic Problems Using a Saddle Point Variational Formulation

Chemical Engineering Transactions, 2019
Variational methods are useful for finding numerical solutions of differential equations, which are the corresponding Euler-Lagrange equations to the stationary condition of the functional. Usually the functional is a maximum or a minimum with respect to

Capturing functional relations in fluid–structure interaction via machine learning

Royal Society Open Science, 2022
While fluid–structure interaction (FSI) problems are ubiquitous in various applications from cell biology to aerodynamics, they involve huge computational overhead. In this paper, we adopt a machine learning (ML)-based strategy to bypass the detailed FSI

ADSORPTION OF ASSOCIATING FLUIDS AT ACTIVE SURFACES: A DENSITY FUNCTIONAL THEORY

Condensed Matter Physics, 2003
We present a density functional theory (DFT) to describe adsorption in systems where molecules of associating fluids can bond (or associate) with discrete, localized functional groups attached to the surfaces, in addition to other fluid molecules.

Fluid-particle dynamics of nasal drug delivery in a realistic human airway lung model

, 2022
Nasal drug delivery provides a rapid onset of therapeutic effects due to the nasal route's large surface area, high blood flow, and ease of accessibility.

Fluid Balance Variations During the Early Phase of Large Hemispheric Stroke Are Associated With Patients' Functional Outcome

Frontiers in Neurology, 2019
Background: From the variety of factors underlying the ischemia-associated edema formation in large hemispheric stroke (LHS), an increased brain water content during the early phase seems to have a pivotal role for long-lasting tissue damage.

Murine amniotic fluid stem cells contribute mesenchymal but not epithelial components to reconstituted mammary ducts [PDF]

, 2010
Introduction: Amniotic fluid harbors cells indicative of all three germ layers, and pluripotent fetal amniotic fluid stem cells (AFSs) are considered potentially valuable for applications in cellular therapy and tissue engineering.
