Breast cancer resistance protein (BCRP) is one of the key multi-drug resistance proteins, which significantly influences the therapeutic effects of many drugs, particularly anti-cancer drugs. Thus, distinguishing between substrates and non-substrates of BCRP is important not only for clinical use but also for drug discovery and development. In this study, a(More)
—During natural disasters, such as earthquakes, a part of the Internet access infrastructure can be damaged, leaving many users disconnected. At the same time, many people need to communicate to find their relatives and receive official notifications about the current situation. This paper presents an evaluation of different techniques for extending network(More)
Sulfur is a promising cathode material with a high theoretical capacity of 1672 mAh g(-1), however, the practical energy density of Li-S battery is far away from such promising due to its low active material utilization and low sulfur loading. Moreover, the challenges of the low electrical conductivity of sulfur and the high solubility of polysulfide(More)
