The surface brightness fluctuation (SBF) technique is one of the distance measurement methods that has been applied on low galaxy NGC 1052-DF2 yielding a about 20 Mpc implying it to be dark matter deficient galaxy. We assume number giant stars above given luminosity threshold represent SBF magnitude. magnitude depends distance, but this degenerate with star formation history (SFH). Using stella...

The selectivity of electrochemical sensors to ascorbic acid (AA), dopamine (DA), and uric (UA) remains an open challenge in the field biosensing. In this study, selective mechanisms for detecting AA, DA, UA molecules on graphene oxide substrates were illustrated through charge population analysis from density functional theory (DFT) calculation results. Our substrate models contained 1:10 oxyge...

How diffuse dwarf galaxies that are deficient in dark matter—such as NGC1052-DF2 and NGC1052-DF4—formed remains a mystery. Along with their luminous member globular clusters (GCs), the so-called matter (DMDGs) have challenged observers theorists alike. Here we report suite of galaxy collision simulations using adaptive mesh refinement code Enzo 1.25 pc resolution, which demonstrates high-veloci...

OBJECTIVE To evaluate the efficacy of NESTROFT (Naked Eye Single Tube Red Cell Osmotic Fragility Test) as a screening tool for detection of beta thalassemia trait. DESIGN Prospective study. SETTING Field camps in various parts of Gujarat and Maharashtra States. METHODS A total of 2525 subjects were screened. NESTROFT, complete hemogram including red cell indices and calculation of Mentzer...

Vacancies in graphene present sites of altered chemical reactivity and open possibilities to tune graphene properties by defect engineering. The understanding of chemical reactivity of such defects is essential for successful implementation of carbon materials in advanced technologies. We report the results of a systematic DFT study of atomic adsorption on graphene with a single vacancy for the...

Measurements of the proton structure function F2 for 0:11 < Q 2 < 20000 GeV 2 and 1:2 10 5 < x < 0:65 from ZEUS 1994-1997 measurements are presented. From ZEUS 1994 and 1995 F2 data the slopes dF2=d lnQ 2 at xed x and d ln F2=d ln(1=x) for x < 0:01 at xed Q 2 are derived. For the latter E665 data are also used. The transition region in Q2 is explored using the simplest non-perturbative models a...

Feline infectious peritonitis (FIP) is an invariably fatal disease of cats caused by systemic infection with a feline coronavirus (FCoV) termed feline infectious peritonitis virus (FIPV). The lethal pathology associated with FIP (granulomatous inflammation and T-cell lymphopenia) is thought to be mediated by aberrant modulation of the immune system due to infection of cells such as monocytes an...

We use spectral energy distribution (SED) fitting to place constraints on the stellar population properties of 29 quiescent ultra-diffuse galaxies (UDGs) across different environments. fully Bayesian routine PROSPECTOR coupled with archival data in optical, near, and mid-infrared from Spitzer WISE under assumption an exponentially declining star formation history. recover mass, age, metallicity...
