Extragalactic black hole X-ray binaries LMC X-1 and X-3 are the persistent sources, usually found in soft spectral state. We present results from timing study of these sources using MAXI, NICER, NuSTAR AstroSat observations carried out during 2014-2020. Study long-term MAXI lightcurve shows that fractional variability flux 2-10keV is moderate ($\sim$20%) LMCX-1 high ($\sim$50%) LMCX-3. The ener...

The observations of high redshifts quasars at $z\gtrsim 6$ have revealed that supermassive black holes (SMBHs) mass $\sim 10^9\,\mathrm{M_{\odot}}$ were already in place within the first $\sim$ Gyr after Big Bang. Supermassive stars (SMSs) with masses $10^{3-5}\,\mathrm{M_{\odot}}$ are potential seeds for these observed SMBHs. A possible formation channel SMSs is interplay gas accretion and run...

Abstract We study the relation between obscuration and supermassive black hole (SMBH) accretion using a large sample of hard X-ray selected active galactic nuclei (AGNs). find strong decrease in fraction obscured sources above Eddington limit for dusty gas ( <m...

We present and analyze a parallel method for the solution of partial diierential equation models of the nervous system. These models mathematically are one-dimensional nonlinear parabolic equations deened on branching domains. Implicit methods for these equations leads to numerical solution of diagonally dominant almost tridiagonal linear systems at each time step. We rst review some exact meth...

We present the results of a 10 ks XMM-Newton observation of NGC 3998, a " type-I " LINER galaxy (i.e., with significant broad Hα emission). Our goal is to test the extent to which radiatively-inefficient accretion flow (RIAF) models and/or scaled-down AGN models are consistent with the observed properties of NGC 3998. A power-law fit to the XMM-Newton spectra results in a power-law slope of Γ =...

In the present work, forming limit diagrams and strain distribution profile diagrams for extra deep drawing steel at room and elevated temperatures have been determined experimentally by conducting stretch forming experiments by using designed and fabricated warm stretchforming tooling setup. With the help of forming Limit Diagrams (FLDs) and strain, distribution profile diagrams the formabilit...

Energy consumption is an important parameter in the context of the wireless sensor networks (WSNs). Several factors can cause energy over consumption such as mobility, node position (relay or gateway), retransmissions... In this paper, we described a new Energy-Degree Distance(EDD) Clustering Algorithm for the WSNs. A node with higher residual energy, higher degree and closer to the base statio...

In this study we compare the cycle-time and on-time-delivery performance of the Critical Ratio (CR), the Earliest Due Date (EDD), and the Operation Due Date (ODD) dispatching rules in semiconductor wafer manufacturing. In addition, we comment on the robustness of the rules to low target flow factor values. It turns out that EDD has almost no positive effect on on-time delivery compared to First...

The PANDA detector at the future Facility for Antiproton and Ion Research (FAIR) is currently being constructed in Darmstadt, Germany. It contains a fixed proton target an antiproton beam with momentum range between 1.5 GeV/c to 15 GeV/c. Two Cherenkov detectors are used identify charged hadrons. Disc DIRC (EDD) covers polar angles 5° 22° endcap region. In order test performance of EDD prototyp...

Introduction: Pulmonary involvement secondary to Systemic Sclerosis (SSc) is the major cause of morbidity and mortality in SSc patients. We designed this study to determine the correlation of important lung function parameters with lung High Resolution CT (HRCT) scan findings. Materials and Methods: Thirty–two consecutive diffuse SSc patients with pulmonary fibrosis were enrolled in this cross...
