With the first multi-messenger observation of a binary neutron star merger (GW170817) new constraints became available for masses and radii stars. We introduce class hybrid EoS that fulfils all these predicts region in mass-radius diagram could be populated only by stars with quark matter cores. A confirmation this conjecture would provided when NICER radius measurement high-mass pulsar PSR J07...

BACKGROUND In 2010, the World Health Organization (WHO) released revised guidelines for prevention of mother-to-child human immunodeficiency virus (HIV) transmission (PMTCT). We projected clinical impacts, costs, and cost-effectiveness of WHO-recommended PMTCT strategies in Zimbabwe. METHODS We used Zimbabwean data in a validated computer model to simulate a cohort of pregnant, HIV-infected w...

We derive the thin film approximation including roughness-induced correctors. This corresponds to the description of a confined Stokes flow whose thickness is of order ε (designed to be small) ; but we also take into account the roughness patterns of the boundary that are described at order ε, leading to a perturbation of the classical Reynolds approximation. The asymptotic expansion leading to...

We calculate crustal properties of neutron stars, namely, mass ( $$M_\mathrm{crust}$$ ), radius $$R_\mathrm{crust}$$ ) and fraction moment inertia $$\Delta I/I$$ from parametrizations hadronic relativistic mean-field (RMF) model consistent with symmetric asymmetric nuclear matter constraints, as well some stellar boundaries. verify which one are also in agreement restrictions I/I \geqslant 1.4\...

In recent years our understanding of the dense matter equation state (EOS) neutron stars has significantly improved by analyzing multimessenger data from radio/X-ray pulsars, gravitational wave events, and nuclear physics constraints. Here we study additional impact on EOS jointly estimated mass radius PSR J0740+6620, presented in Riley et al. a combined set X-ray telescopes NICER XMM-Newton. W...

Aflatoxin M1 is a threatening risk to the safety of milk and can be potent health hazard. Being it known for its zoonotic traits as well, has binding affinity casein in relatively stable during cold storage. The purpose study estimate prevalence AFM1 bulk tank representative samples commercial household dairy establishments across four tehsils Jammu associated factors. A total 620 (6620 individ...

The recent NICER measurement of the radius neutron star PSR J0740+6620, and inferred small variation radii from 1.4$M_\odot$ to 2.1$M_\odot$, reveal key features equation state matter. pressure rises rapidly in regime baryon density $n \sim$ 2-4 times nuclear saturation density, $n_0$ -- region where we expect hadronic matter be undergoing transformation into quark is greater than predicted by ...

We perform a Bayesian analysis of neutrons star moment inertia by utilizing the available gravitational-wave data from LIGO/Virgo (GW170817 and GW190425) mass-radius measurements Neutron Star Interior Composition Explorer (PSR J0030+0415 PSR J0740+6620), incorporating possible phase transition in pulsar inner core. find that A double binary J0737-3039 is $\sim1.30\times10^{45}\,{\rm g\,cm^2}$, ...

In this work we consider strange stars formed by quark matter in the color-flavor-locked (CFL) phase of color superconductivity. The CFL is described a Nambu-Jona-Lasinio model with four-fermion vector and diquark interaction channels. effect superconducting medium on gluons are incorporated into including gluon self-energy thermodynamic potential. We construct parametrizations varying coupling...
