Simultaneous multi-frequency observation of the unknown redshift blazar PG 1553+113 in March-April 2008 [PDF]
, 2010 The blazar PG 1553+113 is a well known TeV gamma-ray emitter. In this paper, we determine its spectral energy distribution using simultaneous multi-frequency data in order to study its emission processes.

A New Family of Extended Lindley Models: Properties, Estimation and Applications
Mathematics, 2020 There are many proposed life models in the literature, based on Lindley distribution. In this paper, a unified approach is used to derive a general form for these life models.

Bimatrix variate Kummer-gamma distribution
Results in Applied Mathematics, 2021 In this article, we propose a bimatrix variate Kummer-gamma distribution. Several properties of this distribution including moment generating function, marginal and conditional distributions, moments are also derived.

An accurate test for homogeneity of odds ratios based on Cochran's Q-statistic [PDF]
, 2015 Background: A frequently used statistic for testing homogeneity in a meta-analysis of K independent studies is Cochran's Q. For a standard test of homogeneity the Q statistic is referred to a chi-square distribution with K - 1 degrees of freedom. For the

Harrod–Domar Growth Model with Memory and Distributed Lag
Axioms, 2019 In this paper, we propose a macroeconomic growth model, in which we take into account memory with power-law fading and gamma distributed lag. This model is a generalization of the standard Harrod–Domar growth model.

Process Monitoring Using Truncated Gamma Distribution
Stats, 2023 The time-between-events idea is commonly used for monitoring high-quality processes. This study aims to monitor the increase and/or decrease in the process mean rapidly using a one-sided exponentially weighted moving average (EWMA) chart for the ...

Are There MeV Gamma-Ray Bursts? [PDF]
, 1995 It is often stated that gamma-ray bursts (GRBs) have typical energies of several hundred keV. Is this a real feature of GRBs or is it due to an observational bias?

, 2007 Let A be a compact set in the right-half plane and $\Gamma(A)$ the set in $\mathbb{R}^{3}$ obtained by rotating A about the vertical axis. We investigate the support of the limit distribution of minimal energy point charges on $\Gamma(A)$ that interact ...

QCD calculation of J/psi+gamma mass distributions
, 1993 We compute the J/psi+gamma invariant-mass distributions from the QCD subprocess g + g --> J/psi+gamma. At large masses, this subprocess is the dominant mechanism for J/psi+gamma production, and data could provide a good test of QCD. The mass distribution
