The purpose of this study is to evaluate the steaming-induced chemical transformation of red ginseng manufactured from fresh ginseng by means of simultaneous quantitative and qualitative analyses with a combinative high-performance liquid chromatography-electrospray tandem mass spectrometry (HPLC-ESI-MS/MS(n)) technique. Thirty-six ginsenosides were(More)
Shuanglong formula (SLF), a Chinese medicine composed of panax ginseng and salvia miltiorrhiza exhibited significant effect in the treatment of myocardial infarction (MI) in clinical. Because of the complex nature and lack of stringent quality control, it's difficult to explain the action mechanism of SLF. In this study, we present a "system to system"(More)
We consider the problem of efficiently using smartphone users to augment the stationary infrastructure sensors for better situation awareness in smart cities. We envision a dynamic sensing platform that intelligently assigns sensing tasks to volunteered smartphone users, in order to answer queries by performing sensing tasks at specific locations that may(More)
Software-Defined Networking (SDN) is an emerging network architecture that enables network programmability. Recent research activities on SDN make it important to develop an emulator that accurately emulates OpenFlow-enabled SDN networks. However, existing emulators and simulators focus on either data plane performance or software switches. This motivates(More)
