Abstract—Graph-based ranking models have been widely applied in information retrieval area. In this paper, we focus on a well known graph-based model - the Ranking on Data Manifold model, or Manifold Ranking (MR). Particularly, it has been successfully applied to content-based image retrieval, because of its outstanding ability to discover underlying geometrical structure of the given image d…
a b s t r a c t Activated carbons with high volumetric capacitance are prepared from apricot shell by optimizing the carbonization temperature prior to NaOH activation to balance the porosity and density. The carbonization temperature has a marked effect on both the pore structure and the electrochemical performances of the activated carbons. As the carbonization temperature increases, the …
Abstract. Nitrogen-doped porous carbons are very simply prepared by direct pyrolysis of a nitrogen-containing organic salt, the tetrasodium salt of ethylenediamine tetraacetic acid for example, at 600–900 ◦C in an inert atmosphere without activation. The porosity and surface chemistry of the carbon depend strongly on the pyrolysis temperature. The surface area and pore volume increase w…
Abstract. Poly(vinylidene fluoride)-derived ultramicroporous carbon with a specific surface area of 1012 m2 g-1 and a very narrow pore-size distribution peaked at 0.55 nm is investigated as electrode material for supercapacitors. The unique microstructure features enable the carbon to present not only a high gravimetric capacitance (264 F g-1) but also a high electrode density (0.826 g cm…
How do trade and foreign direct investment (FDI) policies impact the decisions of firms in technology adoption (process vs. product innovations) and sourcing (internal vs. external and foreign vs. domestic)? We use a sample of Chinese firms to address this question. China’s trade and FDI policies lead to different forms of internationalization: ordinary exports, processing exports, majority F…
Abstract. Acid mine drainage (AMD) is often accompanied with elevated concentrations of arsenic, in the forms of arsenite, As(III), and/or arsenate, As(V), due to the high affinity of arsenic for sulfide mineral ores. This review summarizes the major geochemical processes controlling the release, speciation, fate, and distribution of inorganic arsenic in mine drainage and natural systems. A…
Abstract We have conducted a case study of Foxconn’s suicide crisis when 12 Foxconn employees committed suicide during the first 5 months of 2010. In this case study, we have examined Foxconn’s crisis communication strategies during the critical period and explored the failure in crisis communication in terms of the stakeholder approach. Our findings show that Foxconn adopted a mixed respo…
