One of the main goals of intelligent transportation systems (ITS) is economical profit in the form of fuel consumption reduction, efficient use of existing infrastructure, pollution reduction and so on. Certainly, the economical goal is not the only one. Increasing mobility, safety and passenger comfort are other very strong motivations for implementation(More)
Hepatocellular carcinoma (HCC) is a global public health problem which causes approximately 500,000 deaths annually. Considering that the limited therapeutic options for HCC, novel therapeutic targets and drugs are urgently needed. In this study, we discovered that 1,3,5-trihydroxy-13,13-dimethyl-2H-pyran [7,6-b] xanthone (TDP), isolated from the(More)
In recent years, we have witnessed a gold rush of location based services enabled by location awareness and persistent Internet connections of modern smartphones. However, the poor performance of indoor localization remains an obstacle to providing these services effectively inside buildings. Obtaining a comprehensive database of points of interest and high(More)
Measuring traffic flow plays an important role in intelligent transportation systems. In recent years, the technology of sensor network has been brought into the field due to their reliability and non-intrusiveness. In this paper, we propose a framework to reduce the installation and maintenance cost of traffic measuring sensor networks. The key to the(More)
In recent years, wireless sensor networks have been used in applications of data gathering and target localization across large geographical areas. In this paper, we study the issues involved in applying wireless sensor networks to search and rescue of lost hikers in trails and focus on the optimal placement of sensors and access points such that the cost(More)
