A Provincial Perspective of Nonlinear Okun’s Law for Emerging Markets: The Case of South Africa
Studia Universitatis Vasile Goldis Arad, Seria Stiinte Economice, 2020 A provincial analysis of Okun’s law in South Africa is provided in this article from 1996 to 2016. Empirically, we rely on the nonlinear autoregressive distributive lag (N-ARDL) model whilst the Corbae-Ouliaris filter is used to extract the ‘gap ...

Thirring sine-Gordon relationship by canonical methods [PDF]
Eur.Phys.J. C32 (2003) 443-452, 2002 Using the canonical method developed for anomalous theories, we present the independent rederivation of the quantum relationship between the massive Thirring and the sine-Gordon models. The same method offers the possibility to obtain the Mandelstam soliton operators as a solution of Poisson brackets "equation" for the fermionic fields.

Chinese Journal of Chemistry, EarlyView.An efficient silylative kinetic resolution of acyclic secondary benzylic alcohols was achieved using chlorosilanes and new axially chiral guanidine catalysts bearing a methoxy group. Comprehensive Summary New chiral guanidine catalysts having axial chirality containing a methoxy group were synthesized. Subsequently, their catalytic ability was examined

Studia Universitatis Vasile Goldis Arad, Seria Stiinte Economice, 2020 After 1990, the problem of finding econometric models to assess the influence of economic development on the environment becomes a global goal, a central element of regional, national and Community policies.

On the Multi Trace Superpotential and Corresponding Matrix Model [PDF]
Eur.Phys.J.C32:575-582,2004, 2003 We study N=1 supersymmetric U(N) gauge theory coupled to an adjoint scalar superfiled with a cubic superpotential containing a multi trace term. We show that the field theory results can be reproduced from a matrix model which its potential is given in terms of a linearized potential obtained from the gauge theory superpotential by adding some ...

Journal of Lipid Research, 2013 In rat germ cells and spermatozoa, sphingomyelin (SM) contains molecular species with nonhydroxy (n) and 2-hydroxy (h) very-long-chain polyunsaturated fatty acids (V), the most abundant being SMs with (n- and h-) 28:4n-6, 30:5n-6, and 32:5n-6 as acyl ...

Area Preserving Transformations in Non-commutative Space and NCCS Theory [PDF]
Eur.Phys.J. C32 (2003) 135-140, 2003 We propose an heuristic rule for the area transformation on the non-commutative plane. The non-commutative area preserving transformations are quantum deformation of the classical symplectic diffeomorphisms. Area preservation condition is formulated as a field equation in the non-commutative Chern-Simons gauge theory.

Reactions of 1,4‐diborinine derivatives with CO2
ChemPhysChem, Accepted Article.The reaction of CO2 with seven molecules featuring a 1,4‐diborinine central ring has been studied by means of Density Functional Theory calculations. The selected systems present five‐ and six‐membered aza rings surrounding the 1,4‐diborinine with neutral, anion and dianion charges. In all cases, the reaction is exothermic and exergonic.
