We have attempted to review on microscopic calculation of transport coefficients like shear and bulk viscosities in the framework of hadron resonance gas (HRG) model, where a special attention is explored on the effect of ...
General relativity may be an effective theory with higher curvature correction terms in the action. Inclusion of these terms leads to exciting new possibilities, e.g., gravitational and electromagnetic perturbations following ...
The importance of neutral wave dynamics in the understanding of the upper atmospheric processes is well?known. Conventionally, optical methods are used to derive information on the neutral wave dynamics by obtaining gravity ...

Vector-vortex beams, having both phase and polarization singularities, are of great interest for a variety of applications. Generally, such beams are produced through systematic control of phase and polarization of the ...

We report on direct generation of optical vortices from a continuous-wave (cw), Gaussian beam pumped doubly resonating optical parametric oscillator (DRO). Using a 30-mm long MgO doped periodically poled lithium tantalate ...

The asteroid 2014 JO25, considered to be potentially hazardous by the Minor Planet Center, was spectroscopically followed during its close-Earth encounter on 2017 April 19 and 20. The spectra of the asteroid were taken ...
We study the rare decay B?K?2(1430)(?K?)?+?? in the Standard Model and beyond. Working in the transversity basis, we exploit the relations between the heavy-to-light form factors in the limit of heavy quark (mb??) and large ...
This is the first study to characterize the variation and emission of C2-C5 non-methane volatile organic compounds (NMVOCs) in a semi-urban site of western India based on measurements during February�December 2015. ...
We have derived the differential equation governing the evolution of the photon sphere for dynamical black hole spacetimes with or without spherical symmetry. Numerical solution of the same depicting evolution of the photon ...
We study the implications of the Dark-LMA (DLMA) solution to the solar neutrino problem for neutrinoless double beta decay (0???). We show that, while the predictions for the effective mass governing 0??? remain unchanged ...

In this paper, our prime objective is to connect the curvature of our observable De Sitter Universe with the spectroscopic study of entanglement of two atoms in an open quantum system (OQS). The OQS considered in our work ...
The Experiment to Detect the Global Epoch of reionization Signature (EDGES) collaboration has reported an excess absorption dip in the 21 cm signal during cosmic dawn era. The stronger than expected 21 absorption signal ...
One unanswered question about the binary neutron star coalescence GW170817 is the nature of its post-merger remnant. A previous search for post-merger gravitational waves targeted high-frequency signals from a possible ...
Advanced LIGO's second observing run (O2), conducted from 2016 November 30 to 2017 August 25, combined with Advanced Virgo's first observations in 2017 August, witnessed the birth of gravitational-wave multimessenger ...
Black holes have often provided profound insights into the nature of gravity and the structure of space�time. The study of the mathematical properties of black objects is a major research theme of contemporary theoretical ...
The one-loop self-energy of the neutral�?�meson is obtained for the effective�???�and�?NN�interaction at finite temperature and density in the presence of a constant background magnetic field of arbitrary strength. In our ...
We explore the challenging but phenomenologically interesting hierarchical mass spectrum of Inert Doublet Model where relatively light dark matter along with much heavier scalar states can fully satisfy the constraints on ...

Most of the real world complex networks such as the Internet, World Wide Web and collaboration networks are huge; and to infer their structure and dynamics one requires handling large connectivity (adjacency) matrices. ...
