In social and economic analysis of longitudinal data, the socio-economic variables that are statistically significant in pooled data regressions sometimes become insignificant after individual fixed effects are controlled for. This phenomenon has been observed in the analysis of the relationship...

Researchers consistently argue that organizations need to generate creative ideas to ensure long-term success and survival. One possible solution for increasing creativity is to inject “fresh blood” into the organization by hiring new employees. However, past work suggests there may be a...

Shale inhibition, low-temperature performance, the ability to prevent calcium and magnesium-ion pollution, and hydrate inhibition of polyethylene glycol drilling fluid were each tested with conventional drilling-fluid test equipment and an experimental gas-hydrate integrated simulation system...

A method is proposed that uses renewable solar energy to supply energy for the exploitation of marine gas hydrates using thermal stimulation. The system includes solar cells, which are installed on the platform and a distributor with electric heaters. The solar module is connected with electric...

China's rapid urbanization and industrialization made it the world's largest refined copper producer and consumer. Insufficient copper ore reserves necessitated significant imports. Using material flow and scenario analysis, this study examined historical copper supply and assessed future...

Electrochromic devices that reversibly switch between yellow and green have great potential in adaptive camouflage. However, such device with excellent performances for practical applications is scarce. Herein, we fabricated a new dual conjugated polymer electrochromic device based on two...

The implementation of the thermal mass of envelope and intelligent controls to the building is a key solution to improve energy flexibility. This study researched the energy flexibility of PCM-based multi-layer wall (PCMMW) from systematic nature of building design and operation control. A new...
