When a platform is an optional intermediary, should it require price coherence, i.e., that sellers charge the same price to the platform’s users as they charge their direct customers? If the platform does this, how will it affect consumers’ and overall welfare? In a model leveraging insight...

In the present work, the impact of purge time on the performance of TFTs was systematically investigated because both ZnO channel layers and Al 2 O 3 insulators were deposited using deionized water (H 2 O) as oxidant at low temperature. Compared with the Al 2 O 3 thin films (short purge time),...

Although personal information privacy concerns have been around for years, the introduction of E‐commerce and its associated technologies presents privacy concerns anew. The Fortune 500 represents traditional leadership in the use of technologies and business practices. This preliminary study...

To minimize traffic congestion, understanding how traffic dynamics depend on network structure is necessary. Many real-world complex systems can be described as multilayer structures. In this paper, we introduce the idea of layers to establish a traffic model of two-layer complex networks. By...

Nanometer magnetic solid base catalysts were prepared by loading CaO on Fe3O4 with Na2CO3 and NaOH as precipitator, respectively. The optimum conditions for preparation of this catalyst were investigated. The influence of the proportion of Ca2+ to Fe3O4 on the catalytic performance has been...

In order to improve fuel quality of biomass, a novel biomass crushing system was presented. In this paper there were different biomasses, namely pine chips, corn stalk and cotton stalk, chosen for size reduction study. The production process was described and physical characteristics (particle...

Dehydrated Xilinhaote lignite (XL) and Huolinguole lignite (HL) were depolymerized in supercritical methanol at 310°C and the resulting soluble reaction mixtures were analyzed with GC/MS. The results show that the GC/MS-detectable species can be classified into hydroxybenzenes (HBs), esters,...

Although the World Wide Web has opened the door for businesses and consumers across the globe, many issues and challenges remain in order to take full advantage of this unprecedented opportunity. More specifically, businesses engaged in electronic commerce can take advantage of current...
