Using the QCD operator product expansion, we derive the real part of the transverse and longitudinal vector-vector correlation function with the quantum numbers of the ρ and ω mesons to leading order in density and three momentum (q2) for ω2 → −∞. The operator product expansion provides, through the Borel transformed energy dispersion relation, a model independent constraint for the momentum de...

$f(Q,T)$ gravity is a novel extension of the symmetric teleparallel where Lagrangian $L$ represented through an arbitrary function nonmetricity $Q$ and trace energy-momentum tensor $T$ \cite{fqt}. In this work, we have constrained widely used model form $f(Q,T) = Q^{n+1} + m T$ from primordial abundances light elements to understand its viability in Cosmology. We report that can elegantly expla...

In multimedia networks, certain applications (e.g., voice and video sessions) can tolerate some delay violations and packet losses. For these applications, in [2] we proposed a novel, more flexible traffic characterization approach-Lp-sense constraint functions-as a generalization of deterministic constraint function. Intuitively, feeding more packets than provided resources will degrade the Qu...

Conformance checking confronts process models with real process executions to detect and measure deviations between modelled and observed behaviour. The core technique for conformance checking is the computation of an alignment. Current approaches for alignment computation rely on a shortest-path technique over the product of the state-space of a model and the observed trace, thus suffering fro...

background: asthma is a multifactorial disease and its severity varies with the inflammatory grade. there are conflicting reports about the roles of trace elements in asthma. this study examined the effects of zinc (zn), copper (cu), and selenium (se) concentrations in sera of patients with allergic asthma attending ghaem hospital, mashhad, iran. methods: forty-nine patients, aged 10 to 50 year...

background: the method of proton induced x-ray emission (pixe) has been widely used as a sensitive technique to trace elemental analysis in both biological and medical fields. the sensitivity of this powerful method is in the order of ppm .the aim of this work is to analyze structural composition of 4 heavy trace elements with z greater than 24 (mn, fe, cu, zn) in two kinds of gallstones and to...
