Void Galaxy Distribution: A Challenge for $Λ$CDM [PDF]
, 2021 We extract void catalogs from the Sloan Digital Sky Survey Data Release 16 (SDSS DR16) survey and also from the Millennium simulation. We focus our comparison on distribution of galaxies brighter than $M_r < -18$ inside voids and study the mean separation of void galaxies, distance from the void center, and the radial density profile. We find that mean

Phase field modelling voids nucleation and growth in binary systems
Condensed Matter Physics, 2018 We present a comprehensive study of voids formation, nucleation and growth in a prototype model of binary alloys subjected to irradiation by using a combined approach based on phase field and rate theories.

A Performance-Enhanced Liquid Metal-Based Microheater with Parallel Ventilating Side-Channels
Micromachines, 2020 Gallium-based liquid metal can be used as a material for microheaters because it can be easily filled into microchannels and electrified to generate Joule heat, but the liquid metal-based microheater will suffer breakage induced by voids forming within ...

On Temporal Behaviour of Solutions in Thermoelasticity of Porous Micropolar Bodies
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 We consider a porous thermoelastic body, including voidage time derivative among the independent constitutive variables. For the initial boundary value problem of such materials, we analyze the temporal behaviour of the solutions.

Voids in the Cosmic Web as a probe of dark energy
Condensed Matter Physics, 2017 The formation of large voids in the Cosmic Web from the initial adiabatic cosmological perturbations of space-time metric, density and velocity of matter is investigated in cosmological model with the dynamical dark energy accelerating expansion of the ...

Advanced Manufacturing: Polymer & Composites Science, 2021 In the present work, cross-ply and multidirectional laminates were produced by autoclave moulding. Changes in the process parameters led to different microstructural features in terms of fibre volume fraction, global void content, and void size.

The feasibility of converting ex-coal mining void into aquaculture in North Kalimantan
Journal of Degraded and Mining Lands Management, 2023 Ex-coal mining void has changed landscape shape, physical-chemical, and soil biological properties. As a form of post-mining management, the company must restore damaged land and increase its benefits for the surrounding community, one of which is as a ...

Eigen Value Approach in Micropolar Elastic Medium with Voids
International Journal of Applied Mechanics and Engineering, 2013 The eigen value approach, following the Laplace and Hankel transformation has been employed to find a general solution of the field equations in a micropolar elastic medium with voids for an axisymmetric problem.
