This paper analyzes the correlation between catastrophe (cat) bonds and four other asset classes before and during the COVID-19 pandemic. Using a DCC-GARCH model and a dummy variable regression, our study suggests that cat bonds can be used as a strong safe haven for stocks before the pandemic...

Multifunctional electrocatalysts are desirable for overall water splitting in the energy conversion and storage fields. In this work, N, S-co-doped carbon nanotubes (CNT-NS) were obtained using a superior cost-effective method. The low-cost multi-walled CNTs were activated under a standard air...

Semi-encapsulated microfiber Mach-Zehnder interferometer is designed and developed for temperature, salinity and pressure (TSP) sensing in seawater. Based on the theoretical analysis, sensing experiment is performed with typical sensitivities of -2312 pm/℃, 631 pm/‰, and 3775 pm/MPa,...

This paper examines how decentralization of administrative and fiscal authority affects the development of small cities by exploiting a unique reform of county-to-city upgrading (chexiansheshi) in China. Based on a comprehensive county-level dataset and difference-in-difference approach, I...
