INNOVATION AND INSTITUTIONAL QUALITY ON ECONOMIC GROWTH IN ASIA

When looking at the different effects of institutional quality on economic development, namely control of corruption, there are two different hypotheses that explain such effects. One is the “grease the wheel” hypothesis, which predicts that corruption is beneficial for growth, and the other one is the “sand the wheel” hypothesis, which says the opposite. Corruption is normally blamed for the slow economic growths in some countries, but some Asian countries’ exponential growths have proven the “grease the wheel” hypothesis otherwise. The “Asian experience”1 phenomenon occurs when corruption does not seem to hamper business activities in some Asian countries. This research will focus on finding how institutional quality variables, such as corruption control and government effectiveness, can correlate with innovation variables to contribute to economic growth. Using data and examples from Asian countries, this study finds a positive correlation between corruption and economic growth in some developed countries, such as China and South Korea

Rateless codes-based secure communication employing transmit antenna selection and harvest-to-jam under joint effect of interference and hardware impairments

In this paper, we propose a rateless codes-based communication protocol to provide security for wireless systems. In the proposed protocol, a source uses the transmit antenna selection (TAS) technique to transmit Fountain-encoded packets to a destination in presence of an eavesdropper. Moreover, a cooperative jammer node harvests energy from radio frequency (RF) signals of the source and the interference sources to generate jamming noises on the eavesdropper. The data transmission terminates as soon as the destination can receive a sufficient number of the encoded packets for decoding the original data of the source. To obtain secure communication, the destination must receive sufficient encoded packets before the eavesdropper. The combination of the TAS and harvest-to-jam techniques obtains the security and efficient energy via reducing the number of the data transmission, increasing the quality of the data channel, decreasing the quality of the eavesdropping channel, and supporting the energy for the jammer. The main contribution of this paper is to derive exact closed-form expressions of outage probability (OP), probability of successful and secure communication (SS), intercept probability (IP) and average number of time slots used by the source over Rayleigh fading channel under the joint impact of co-channel interference and hardware impairments. Then, Monte Carlo simulations are presented to verify the theoretical results.Web of Science217art. no. 70

Generalized self-energy embedding theory

Ab initio quantum chemistry calculations for systems with large active spaces are notoriously difficult and cannot be successfully tackled by standard methods. In this letter, we generalize a Green's function QM/QM embedding method called self-energy embedding theory (SEET) that has the potential to be successfully employed to treat large active spaces. In generalized SEET, active orbitals are grouped into intersecting groups of few orbitals allowing us to perform multiple parallel calculations yielding results comparable to the full active space treatment. We examine generalized SEET on a series of examples and discuss a hierarchy of systematically improvable approximations
