1. IntroductionThe artificial intelligence (AI) industry has emerged as a strategic sector and a central driver of the Fourth Industrial Revolution, sparking extensive scholarly discourse. As defined by the Organization for Economic Co-operation and Development (OECD), an AI system is a machine-based system that can make predictions, recommendations, or decisions that influence real or virtual environments for a given set of human-defined objectives [1].

The commercialization of intellectual property has become a fundamental avenue for universities to improve regional competitiveness. However, large-scale empirical studies on patent transfers, reflecting technology and knowledge sharing, remain limited. This study used social network analysis to investigate university technology flows in China based on patent assignments from technological, organizational, and regional perspectives. The results firstly revealed clear stage characteristics in the number of university patent assignments with the improvement of the Chinese version of the Bayh-Dole Act. Secondly, popular technologies in university technology flows mainly concentrated on measurement, testing, digital transmission, and other areas in which enterprises lack international competitive advantage. Thirdly, central actors comprised prestigious universities focusing on science, engineering, and comprehensive disciplines, along with intellectual property-focused enterprises. Finally, university technology flows gradually delocalized, and varied regional patterns exist owing to a spatial mismatch between university knowledge supply and regional demand. These findings have several practical and policy implications for government and university management in terms of promoting emerging technologies and clarifying universities’ functions in regional and national innovation systems. This study contributes to the economic geography literature on regional innovation.

AbstractUnderstanding the motion of charged particles in the electromagnetic field in the inner magnetosphere is essential for space science and space weather. Charge accumulation can occur due to the dipole magnetic and convective electric fields in this region. However, until the recent Magnetospheric Multiscale (MMS) mission, there were few means to detect charge distribution in situ.

1 Introduction SYM-H index is a geomagnetic index introduced to describe the strength of geomagnetic storms (Mayaud, 1980). It is determined by the 1-min average of the horizontal component of the geomagnetic disturbance measured by several ground stations located near the equatorial regions with low latitude, which is similar to Dst index with 1 hr resolution (Wanliss & Showalter, 2006).
