Cosmological Constant Effects on the Properties of Mass Twin Compact Stars [PDF]

EPJ Web of Conferences, 2019
We present a systematic investigation of the cosmological constant effects in compact stars interiors in the framework of Einstein’s gravity. Consideration of a cosmological constant Λ in compact stars is motivated by the mechanism of acceleration of the

Ultrahigh concentration exfoliation and aqueous dispersion of few-layer graphene by excluded volume effect

Nature Communications
Colloidal properties of nanoparticles are intricately linked to their morphology. Traditionally, achieving high-concentration dispersions of two-dimensional (2D) nanosheets has proven challenging as they tend to agglomerate or re-stack under increased ...

Equation of state of neutron star matter and its warm extension with an interacting hadron resonance gas

Physics Letters B, 2022
We propose an interpolating equation of state that satisfies phenomenologically established boundary conditions in two extreme regimes at high temperature and low baryon density and at low temperature and high baryon density.

Numerical study of the phase behavior of rod-like colloidal particles with attractive tips

AIP Advances, 2021
Suspensions of anisometric particles are known to self-assemble into various liquid crystal (LC) phases, namely, the nematic, smectic (A or B or both), and in some cases, columnar phases, due to the effects of excluded volume.

Using synthetic bacterial enhancers to reveal a looping-based mechanism for quenching-like repression

Nature Communications, 2016
Some repressors down-regulate gene expression when they bind to a site up to 100 base pairs away from the nearest activator. Here, the authors show that this quenching-like repression can be achieved by the excluded volume effect when a DNA-bound protein

An analysis of Methylenetetrahydrofolate reductase and Glutathione S-transferase omega-1 genes as modifiers of the cerebral response to ischemia

BMC Neurology, 2009
Background Cerebral ischemia involves a series of reactions which ultimately influence the final volume of a brain infarction. We hypothesize that polymorphisms in genes encoding proteins involved in these reactions could act as modifiers of the cerebral

Entropic tension in crowded membranes. [PDF]

PLoS Computational Biology, 2012
Unlike their model membrane counterparts, biological membranes are richly decorated with a heterogeneous assembly of membrane proteins. These proteins are so tightly packed that their excluded area interactions can alter the free energy landscape ...

Strange Quark Stars: The Role of Excluded Volume Effects

Universe
We study cold strange quark stars employing an enhanced version of the quark-mass density-dependent model, which incorporates excluded volume effects to address non-perturbative QCD repulsive interactions.

Transverse magnetic field on Jeffery–Hamel problem with Cu–water nanofluid between two non parallel plane walls by using collocation method

Case Studies in Thermal Engineering, 2014
An analysis has been performed to study the problem of magneto-hydrodynamic (MHD) Jeffery–Hamel flow with nanoparticles. The governing equations for this problem are reduced to an ordinary form and is solved using collocation method (CM) and numerically ...

Preoperative evaluation of liver volume in living donor liver transplantation

İstanbul Kuzey Klinikleri, 2018
INTRODUCTION[|]The aim of the present study was to retrospectively evaluate the difference between the preoperative estimated volume and the actual intraoperative graft volume determined in donor right hepatectomies and to evaluate the possible effect of
