Scientific collaboration and the resulting outputs have been always of interest to the scientific community. Specifically, drawing and understanding the elements of scientific collaboration network and identifying its determinants are important step in prescribing and implementing policies in various fields and disciplines of science. Focusing on the Iran context, this study examines the scientific collaborations of faculty members in selected Iranian universities (Sharif University of Technology, University of Tehran, Iran University of Science and Technology, Amirkabir University of Technology, Isfahan University of Technology, and Ferdowsi University of Mashhad). We have drawn the... 

Many researchers believe that the production of knowledge is a cumulative process based on past learning, and on the other hand, deepening in a specialized knowledge causes fundamental changes in that field. so to justify the existing relationships, the concept of knowledge spillover is taken into consideration. Knowledge spillover means that technologies can benefit from knowledge originating in other technologies. Our goal in this research is to identify the mechanisms and type of knowledge that can affect the flow between different industries and countries. With the increasing need of the countries of the world for energy and the environmental hazards of fossil energies, an important... 

Considering the role of artificial intelligence and the opening of the window of opportunity to use this technology and the possibility of catching-up it, in this research, the factors affecting the technological catching-up of artificial intelligence in countries have been studied. By using the components of the technology regime, the impact of each component on the technological convergence of artificial intelligence in leading and latecomer countries has been investigated, and the indicators of technological appropriability, Cumulativeness of technological innovation, originality, Technological cycle, Concentration and Diversity to understand the changes in the share of patents of... 

Artificial intelligence is a field that has made another revolution in the Fourth Industrial Revolution and has become one of the most widely used emerging technologies in the present era. Further investigation of the trends in this field shows that it has shown increasing growth in recent years. Also, in the future, this trend will continue and fundamental changes will occur in societies. For this reason, countries must definitely pay the necessary and sufficient attention to this field in their growth and development path. To achieve this growth path, it is intended to evaluate the status of leading countries in the field of artificial intelligence using two key variables in technological...
