With the presence of both switching cost and network externality, this paper builds a two-stage model for competition between two platforms. In stage one, an incumbent platform controls the market as a monopolist and sets a price to acquire a user base. In stage two, a new platform enters the...

Recent policy discussions have debated whether governments should treat state-owned and private enterprises equally or adopt different policies towards each type of enterprise. Such questions are pertinent for difficult economic climates in which government subsidy towards struggling state-owned...

The equal-height-difference passive heat removal system (EHDPHRS) utilizes ocean as ultimate heat sink and the reverse flow of seawater may leading to condensation-induced water hammer (CIWH). In this study, the integration of volume of fluid model and condensation model based on surface renewal...

The complex seawater matrix has significantly influenced the determination of estuarine dissolved Hg(II), hindering its monitoring and risk assessment. In this work, the SiO2-SH-DGT assembled by the SiO2-SH crygel as the novel binding phase was developed to tackle this problem. The uniform...

The equal-height-difference passive heat removal system (EHDPHRS) via natural circulation driving and utilizes ocean as infinite heat sink for heat dissipation, showing broad application prospect in ocean nuclear power field; but the heat removal pipe normally encounters the reverse flow of the...
