A rigorous formulation of the cosmological Newtonian limit without averaging
, 2010 We prove the existence of a large class of one-parameter families of cosmological solutions to the Einstein-Euler equations that have a Newtonian limit.

Bioinspired Smart Nanogels for Rapid Blue Laser‐Activated Hemostasis in Gastrointestinal Bleeding
Advanced Materials, EarlyView.Waxberry‐inspired branched‐silica nanogel can swiftly stop bleeding upon blue laser endoscopy for gastrointestinal hemostasis in the esophagus, stomach, and duodenum of mini‐pigs. Abstract Gastrointestinal bleeding (GIB) is a critical condition that requires rapid and effective intervention.

A note on acoustic black holes in neo-Newtonian theory
, 2013 Newtonian fluid dynamics allows the construction of acoustic metrics from which black hole configurations can be studied. However, relativistic pressure effects are neglected within Newtonian theory.

Carreau fluid model for blood flow through a tapered artery with a stenosis
Ain Shams Engineering Journal, 2014 In present article, we have studied the blood flow through tapered artery with stenosis. The non-Newtonian nature of blood in small arteries is analyzed mathematically by considering the blood as Carreau fluid.

On a degenerate parabolic equation with Newtonian fluid∼non-Newtonian fluid mixed type
Journal of Inequalities and Applications, 2021 We study the existence of weak solutions to a Newtonian fluid∼non-Newtonian fluid mixed-type equation u t = div ( b ( x , t ) | ∇ A ( u ) | p ( x ) − 2 ∇ A ( u ) + α ( x , t ) ∇ A ( u ) ) + f ( u , x , t ) .

The Hydrodynamics of Non-Newtonian Fluids. II [PDF]
Mathematical Proceedings of the Cambridge Philosophical Society, 1948 In this paper, the general hydrodynamic theory of visco-inelastic, incompressible, non-Newtonian fluids, developed in a previous paper (l), is applied to the problem of the flow of such a fluid through a tube of circular cross-section. It is found that the absolute values of the normal stress components are no longer uniform over a cross-section of the

Advanced Materials, EarlyView.Closed‐loop and sustainable 4D printing of sulfur‐rich polymer composites is demonstrated for the first time using loosely crosslinked poly(phenylene polysulfide) networks (PSNs) and their magnetic composites (MPSNs). 3D‐printed PSNs and MPSNs exhibit shape‐morphing capabilities and can be directly reprinted into new form factors and magneto‐responsive

Mechanoresponsive Hydrogels Emerging from Dynamic and Non‐Covalent Interactions
Advanced Materials, EarlyView.Mechanoresponsive behaviors in hydrogels often arise from dynamic or non‐covalent interactions between polymer chains. This review highlights self‐healing, shear‐thinning, shear‐thickening, and strain‐stiffening hydrogels formed through dynamic crosslinking motifs, discussing their underlying mechanisms and emergent applications across biomedical and ...

Numerical study of shear thickening fluid with discrete particles embedded in a base fluid
International Journal of Multiphysics, 2016 The Shear Thickening Fluid (STF) is a dilatant material, which displays non-Newtonian characteristics in its unique ability to transit from a low viscosity fluid to a high viscosity fluid.
