The objective of this paper is to examine the effect trade and financial openness, through technology transfer channel, on total factor productivity (TFP) in a panel developing countries between 1988 2014. According growing body literature subject, there strong link openness eco-nomic growth, but are technological externalities key element for countries? To answer question, we resorted dynamic ...

Ab stract: Ef fec tive ness must be de ter mined for each new tech nol ogy be cause it may have ad van tages and dis ad van tages over what is cur rently of fered. We re viewed the lit er a ture to syn the size in for ma tion on whether telepsychiatry is ef fec tive. Based on the lit er a ture, we sug gest that the ef fec tive ness of telepsychiatry be eval u ated on ac cess to care, qual ity o...

In this paper, the parameter-switching technique was applied to control chaos in Chen oscillator and as a decryption mechanism secure transmission system, transmit RGB grayscale images. past few decades, considerable efforts have been put into study of stabilization chaotic dynamical systems. Most well-known methods, such Ott, Grebogi, Yorke (OGY), Pyragas, open-loop force an unstable periodic ...

Holographic projection is the new wave of technology that will change how we view things in future; it have tremendous effects on all fields life including education and science. Generally, A Hologram a 3D record positive interference laser light waves. Technology three-dimensional hologram (3DH) involves spatial displays which detaches display from user integrate into real environment. This re...

Xinjiang is a vast area of moun tains and desert bas ins that formed the main route for con tact be tween early China and the West. The south ern Talimu Ba sin is well known for the re mark able or ganic pres er va tion there of buri als and aban doned set tle ments. Lesser known is the north ern Zhunge’er Ba sin that lay across the route out to the Eur asian steppes. From at least as early as ...

We investigated the expression and clinical value of the soluble major histocompatibility complex class I-related chain A (sMICA) molecule in the serum of patients with renal tumors. Sixty patients diagnosed with renal tumors were enrolled in the experimental group, whereas 20 healthy volunteers served as the control group. The sMICA levels were measured via enzyme-linked immunosorbent assay, a...

The dynamics behavior of a discrete-time three-species food chain model is investigated. By using bifurcation theory, it shown that the equilibrium point system loses its stability, and undergoes Neimark–Sacker bifurcation, which leads to chaos as parameter changes. chaotic motion controlled on stable periodic period-1 orbit implementation hybrid control strategy. factor affecting time also stu...

In this paper, we extend the OGY chaos-control method to be one based on the invariant manifold theory and the sliding mode control concept. This extended-control method not only can deal with higher order chaotic systems in the same spirit of the OGY method, but also can remove the reliance of the control on eigenvalues and eigenvectors of the system Jacobians, resulting in an even simpler but...

Over the past decade, the problem of chaos controlling in plasmas attracted significant attention due to the importance of this topic for many processes in plasma physics [1-3]. In addition to the general interest of this subject the studies were motivated by the possibility of reduction of the anomalous transport, associated with plasma turbulent phenomena. It is well known that almost all sys...
