Thermophysical Analysis of Water Based (Cu–Al2O3) Hybrid Nanofluid in an Asymmetric Channel with Dilating/Squeezing Walls Considering Different Shapes of Nanoparticles

open access: yesApplied Sciences, 2018
An innovative concept of water-based Cu–Al2O3 hybrid nanofluid has been employed to investigate the behavior of flow and heat transfer inside a rectangular channel whose permeable walls experiences dilation or contraction in height. The transformed

Numerical simulation and dynamic mode decomposition analysis of the flow past wings with spanwise waviness

open access: yesEngineering Applications of Computational Fluid Mechanics, 2022
This paper presents an investigation on the compressible flow past spanwise wavy wings with an incoming flow of [Formula: see text] and [Formula: see text]. The scale adaptive simulation is employed here to solve the Favre-averaged equations. Three wings,

Soft-Pion Theorems for Large Scale Structure

open access: yes, 2014
Consistency relations -- which relate an N-point function to a squeezed (N+1)-point function -- are useful in large scale structure (LSS) because of their non-perturbative nature: they hold even if the N-point function is deep in the nonlinear regime ...

Nonstandard Approach to Gravity for the Dark Sector of the Universe

open access: yesEntropy, 2013
We summarize the present state of research on the darkon fluid as a model for the dark sector of the Universe. Nonrelativistic massless particles are introduced as a realization of the Galilei group in an enlarged phase space.

Patient‐Derived 3D Bioprinted Cardiac Organoid Constructs Reveal Key Pathological Features of Duchenne Muscular Dystrophy

open access: yesAdvanced Healthcare Materials, EarlyView.
Patient‐derived cardiac organoids reveal key features of Duchenne muscular dystrophy cardiomyopathy, including apoptosis, oxidative stress, calcium handling defects, and mechanical remodeling. By integrating organoids into alginate–gelatin bioprinted constructs, disease phenotypes are organized into scalable 3D cardiac tissues displaying extracellular ...

Accretion of matter by a charged dilaton black hole

open access: yesEuropean Physical Journal C: Particles and Fields
Considering accretion onto a charged dilaton black hole, the fundamental equations governing accretion, general analytic expressions for critical points, critical velocity, critical speed of sound, and ultimately the mass accretion rate are obtained.
