Present study examines turbulent structures of a rough bed open-channel flow in the context of deterministic approach. Instantaneous velocity field is measured in different hydraulic conditions using two dimensional Particle Image Velocimetry (PIV) in vertical plane and Stereoscopic PIV in horizontal plane. Different techniques and quantities such as swirl strength, two-point and cross-correlat...

In this paper we study the chiral symmetry breaking in the hard wall AdS/QCD model. We solve the equations of motion up to the second order at large momentum and obtain the first few terms in the expansion of the ”left-right” correlator, which is the measure of symmetry breaking. In the strong coupling calculation we get the result as the series in square root of t’Hooft constant.

Exact two point correlation functions of sine-Liouville theory are presented for primary fields with U(1) charge neutral, which may either preserve or break winding number. Our result is checked with perturbative calculation and is also consistent with previous one which can be obtained by restricting the action parameters.

A two-point orientation auto-correlation function (TP-OACF) was developed in order to quantify the spatial distribution of targeted texture components. An example of a TP-OACF was demonstrated using an idealized orientation map. Characteristics of the spatial distribution of major texture components in 6022-T4 Al sheets deformed in plane-strain tension were also quantified using a TP-OACF. The ...

Interplanetary turbulence, the best studied case of low frequency plasma turbulence, is the only directly quantified instance of astrophysical turbulence. Here, magnetic field correlation analysis, using for the first time only proper two-point, single time measurements, provides a key step in unraveling the space-time structure of interplanetary turbulence. Simultaneous magnetic field data fro...

Nine of the most important estimators known for the two-point correlation function are compared using a predetermined, rigorous criterion. The indicators were extracted from over 500 subsamples of the Virgo Hubble volume simulation cluster catalog. The "real" correlation function was determined from the full survey in a 3000 h(-1) Mpc periodic cube. The estimators were ranked by the cumulative ...

A collaborative experimental effort in the western Utah salt flats [7] has enabled us to map coherence in turbulent boundary layers at very high Reynolds numbers [Reτ ≈ O(106)]. It is found that the large-scale coherence recently noted in the logarithmic region of laboratory-scale boundary layers [4] is also present in the very high Reynolds number atmospheric surface layer [5]. Two-point corre...

This paper presents a detailed theoretical study of the two-point correlation function ξ for both dark matter halos and the matter density field in five cosmological models with varying matter density Ωm and neutrino fraction Ων . The objectives of this systematic study are to evaluate the nonlinear gravitational effects on ξ, to contrast the behavior of ξ for halos vs. matter, and to quantify ...

The consistent description of unstable particles, renormalons, or other Schwinger–Dysontype of solutions within the framework of perturbative gauge field theories necessitates the definition and resummation of off-shell Green’s functions, which must respect several crucial physical requirements. A formalism is presented for resummation of off-shell twopoint correlation functions, which is mainl...
