Tsinghua SEM-MIT joint team publishes in top scientific journal PNAS

It publishes cutting-edge and top research results with outstanding scientific contributions and exerts extensive scientific influence in various disciplines. It is extremely difficult to publish in on account of its high standards. PNAS articles cover 36 sub-disciplines, such as medicine, chemistry, biology, physics, computer science and social science. Five of its disciplines are directly related to the field of humanities and social sciences: demography, economic science, political science, psychology and cognitive science and social science. It is more difficult to publish research on humanities and social sciences than science and engineering in PNAS.
