The current understanding of urban green space (UGS) recreational service is limited due to the lack of being examined under the logic that underlies the ecosystem service paradigm, leading to limitation sin the application of ecosystem based management in urban land use planning. This paper...

The locomotive scheduling problem (or the locomotive assignment problem) is to assign a consist (a set of locomotives) to each train in a pre-planned train schedule so as to provide them sufficient power to pull them from their origins to their destinations. Locomotive scheduling problems are...

This paper studies the effect of interlock directors’ performance feedback on the acquisition performance of focal firms from the perspective of principal-agent. The results indicate that in the acquisition network connected by interlock directors, the more successful the performance feedback...

CO2 methanation is a promising route for converting CO2 into a marketable natural gas. The major challenge of this process is to enhance CO2 methanation catalytic activity at low temperature. This work showcases a supported-catalysts phase engineering strategy to overcome the challenge. We...

To effectively restore the groundwater environment of the Shiping Mine (SPM) area, which is contaminated by acid mine drainage (AMD), a hydrogeochemical conceptual model was constructed based on groundwater chemistry and environmental stable isotopes. The contribution rate of various pollution...
