Mobile service providers often motivate sales agents to attract more potential customers by sharing part of service revenue with agents. Motivated by the practice in the mobile service industry, we build a theoretical model considering a mobile service chain with a service provider selling...

During coal self-heating, the dehydration process and oxygen consumption by coal with different moisture content were analyzed. The oxidation process of aliphatic hydrocarbons, peroxyl radical, and nitrogen-, and sulfur-containing structures with/without water were evaluated by quantum chemical...

In the present study, a novel type of titanium matrix composite with a quasi-network structure was successfully fabricated by hot-press sintering Ti6Al4V powder and Ti2AlC precursor at 1200 ℃ and 25 MPa. To explore the effect of Ti2AlC content on the microstructure and properties of...

The high cost and low carrier separation efficiency of g-C3N4/Ag2O photocatalysts affect its application in the degradation of organic pollutants. In this study, the CA-β-CD/g-C3N4/Ag2O 2D/0D heterojunction photocatalysts were successfully prepared to enhance the visible light response and...

We thoroughly investigate the spillover effect of individuals' cadre status on socioeconomic outcomes of their biological family members over time using data from the Chinese Adult Twins Survey. A wide spectrum of family ties is analyzed within families. The estimates indicate that cadres'...

We investigate the effectiveness of yield curve control (YCC) vis-à-vis other unconventional monetary policies (UMP) in a panel difference-in-differences framework of 26 economies that employed UMP between 1995 and mid-2021 for countries that made YCC related announcements. Shadow rates are...

This paper proposes a branch-and-bound algorithm (B&B) for the proactive scheduling problem, which incorporates a degree of anticipation for variability in practical projects. First, the resource-constrained proactive scheduling model is formulated. Second, solving its resource-unconstrained...
