The singlet pseudoscalar sector of light mesons is investigated in the soft-wall model, a bottom-up approach to AdS/QCD correspondence. ${\ensuremath{\eta}}^{\ensuremath{'}}$ mass results from mixing among fields dual axial current, current and $G\stackrel{\texttildelow{}}{G}$ operator. topological susceptibility computed for any quark mass, Witten-Veneziano relation obtained large ${N}_{c}$ li...

The mixing characteristics of industrial flotation columns were investigated using computational fluid dynamics (CFD). Particular emphasis was placed on the clarification relationship between liquid and solids parameters such as mean residence time axial dispersion coefficients. effects particle size bubble in column also studied. An Eulerian-Eulerian method applied to simulate multiphase flow,...

a r t i c l e i n f o Continuous powder mixing has attracted a lot of interest within the pharmaceutical industry. Much work has been done recently that targets the characterization of continuous powder mixing. In this paper, a quantitative scaling up strategy is introduced that allows the transition from lab to industrial scale. The proposed methodology is based on the variance spectrum analys...

We discuss the effect of η–η mixing and of axial current anomalies on various decay processes. We describe the 2γ decays of η and η, the radiative decays of low-lying vector mesons as well as the decays η → 3π, J/ψ → ηγ and J/ψ → ηγ in one unified framework, in which they are related to the electromagnetic and strong axial current anomalies, respectively. We also discuss briefly the enhancement...

Axial and lateral pressure loss in a 5 × rod–bundle with split-type mixing vane spacer grid was experimentally measured using differential transmitters at different sub-channel Reynolds numbers (Re) orienting angles. The geometrical parameters of the 5–rod bundle are as follows: they have same diameter (D = 9.5 mm) pitch ( p 12.6 those real fuel rods typical pressurized water reactor (PWR), hyd...

Abstract: Discrete mathematical model was developed for analysis and design of the continuous grinding mill-classifier systems. In the model, the mixing of the material to be ground by the axial dispersion model, the breakage kinetics by the first order breakage law, and the classifier by a usual classification function are described. This model is the basic of computer simulation. Computer pro...

The domain wall fermion formulation exhibits full chiral symmetry for finite lattice spacing except for the effects of mixing between the domain walls. Close to the continuum limit these symmetry breaking effects should be described by a single residual mass. We determine this mass from the conservation law obeyed by the conserved axial current in quenched simulations with β = 5.7 and 6.0 and d...

Abstract This paper have shown an expert system design by using optimization methods for the Focused ion beam FIB optical system, by mixing the dynamic programming procedure and artificial intelligence technique to build an intelligent agent. CADION ANALYZER has been designed as an interpretation expert system, written in Java expert system shell (JESS) and Visual Basic.Net for optimizing and a...

The vector and axial vector current mixing phenomena at low temperature pion gas by Dey, Eletsky and Ioffe, leads to the low temperature correction of the photon-vector meson coupling (gρ) at order ǫ = T 2/6f2 π and the ρ meson mass at order ǫ2. We show how this low temperature theorems involving the photon and vector mesons are satisfied in the chiral models based on hidden gauge symmetry and ...

Two-photon absorption (2PA) and excited state absorption (ESA) properties of axial-bonding type hybrid porphyrin arrays are investigated in the picosecond regime under single-photon resonant excitation condition. A crossover from reverse saturable absorption (RSA) to saturable absorption (SA) and back to RSA is observed with the increase of excitation intensity. In the corresponding intensity r...
