Unemployment hysteresis of Middle East and North African (MENA) countries is investigated under a battery unit root testing frameworks in the extant literature, including recently proposed Panel SUR Dickey-Fuller-like test with Fourier Exponential Smooth Transition Regression (ESTR) nonlinearities. The function allows for smooth nonlinear breaks, while ESTR nonlinearity instantaneous breaks. tw...

Arsenic is atherogenic, carcinogenic, and genotoxic. Because atherosclerotic plaque has been considered a benign smooth muscle cell tumor, we have studied the effects of arsenite on DNA integrity of human vascular smooth muscle cells. By using single-cell alkaline electrophoresis, apparent DNA strand breaks were detected in a 4-hour treatment with arsenite at a concentration above 1 micromol/L....

In this study, we investigate the validity of purchasing power parity (PPP) proposition for 34 European and selected global countries. For purpose, propose a new unit root test cross-sectionally dependent heterogeneous panels that allows gradual structural breaks symmetric nonlinear adjustment toward equilibrium level. The alternative hypothesis stationary is obtained by due to exponential smoo...

This study explores the methods to de-trend smooth structural break processes while conducting unit root tests. The two most commonly applied approaches for modelling breaks namely transition and Fourier functions are considered. We perform a sequence of power comparisons among alternative tests that accommodate or sharp breaks. experiments demonstrate utilizing function lead unexpected results...

Structural Breaks in the Real Exchange Rate Adjustment Mechanism Laurence Copeland and Saeed Heravi We show that the behaviour of the real exchange rates of the UK, Germany, France and Japan has been characterised by structural breaks which changed the adjustment mechanism. In the context of a Time-Varying Smooth Transition AutoRegressive of the kind introduced by Lundbergh et al (2003), we sho...

The rigidity theory for circle homeomorphisms with breaks has been studied intensively in the last 20 years. It was proved [15, 21, 17, 19] that under mild conditions of Diophantine type on rotation number any two $C^{2+\alpha}$ smooth a break point are $C^1$ smoothly conjugate to each other, provided they have same and size break. In this paper we prove conjugacy may not be $C^{2-\nu}$ even if...

Asian countries have experienced many financial catastrophes and pandemics in the past couple of decades. Therefore, evaluating effect structural breaks on economies has taken substantive attention empirical literature. Thus, this study aims to investigate Financial Development (FD) Economic Growth (EG) middle-income Asia. The considered global crisis 2008 as a key break. sample consisted 24 wh...

We consider both analytically and numerically the effect of inhomogeneity of Josephson properties of grain boundaries in YBCO thin films on unquantized (splinter) vortices. It is shown that in general a smooth inhomogeneity breaks the complementarity condition /1 þ /2 1⁄4 /0 relating magnetic fluxes /1 and /2 carried by adjacent splinter vortices. 2003 Elsevier B.V.
