China has adopted a nine-year compulsory schooling system, which means all children are required to attend school for at least nine years. Students have to complete both the primary school program and the junior middle-school program. Higher education is only for those students who have passed examinations of all levels. Student must pass the entrance examination for senior middle schools or middle-level technical schools. After two, three or four years, they have to go through national college entrance examination for admission to universities.
Existing communications and computer architecture are increasingly being limited by the pedestrian speed of electrons moving through wires, and the future of high-speed communication and computing is in optics, experts say. The Holy Grail of results would be "wireless interconnecting," which operates at speeds 100 to 1,000 times faster than current technology. The new discovery, made by researchers at Oregon State University, the University of Iowa and Philipps University in Germany, has identified a way in which nanoscale devices based on gallium arsenide can respond to strong terahertz pulses for an extremely short period, controlling the electrical signal in a semiconductor. The research builds on previous findings for which OSU holds an issued patent.
