This paper exploits a quasi-natural experiment – the U.S. granting of Permanent Normal Trade Relations (PNTR) to China after China's accession to the World Trade Organization – to examine whether trade liberalization affects the incidence of child labor in China. PNTR permanently set U.S....

Driven by unprecedented economic development, China has experienced a rapid urbanization for more than four decades. Such a record speed and scale of China’s urbanization has posed significant challenges to urban sustainability, which are especially critical for ecological fragile cities in...

Even in the harsh environment of tailings area, there are still some naturally growing plants. Exploring its survival mechanism has potential environmental benefits for vegetation restoration in mining area. In this study, the metal(loid) fractions in two alkaline iron tailing areas and the...

Dielectric barrier discharge (DBD) synergistic catalysis technology combines the high reaction activity of a plasma and the high reaction selectivity of a catalyst and has attracted increased attention in recent years. In this work, the conversion of carbonyl sulfide (COS) by DBD combined with a...

The health of rotating machines is critical to the stable operation and safety of nuclear power plants. However, research on machine learning-based rotating machine fault diagnosis is still in its infancy in the nuclear industry. The signal noise generated in the plant may negatively affect the...

Fiber-shaped stretchable strain and temperature sensors are highly desirable for wearable electronics due to their excellent flexibility, comfort, air permeability, and easy to be weaved into fabric. However, developing fiber-shaped strain sensors with the merits of low detection limit, wide...
