Non-native plants spread to recipient areas via natural or human-mediated modes of dispersal, and, if the non-native species are invasive, introduction potentially causes impacts on native and local ecosystems as well economic losses. Therefore, we studied diversity distributional patterns plant in tropical island province Hainan, China its relationships with environmental socioeconomic factors...
By serving two or more passenger requests in each ride ride-sourcing markets, ride-pooling service is now becoming an important component of shared smart mobility. It generally expected to improve vehicle utilization rate, and therefore alleviate traffic congestion reduce carbon dioxide emissions. A few recent theoretical studies are conducted, mainly focusing on the equilibrium analysis market...

The main objective of this special issue is to present readers with the significantly extended and improved versions of several high-quality articles presented at the Third International Conference on Natural Computation (ICNC’07). ICNC’07 was held jointly with The Fourth International Conference on Fuzzy Systems and Knowledge Discovery (FSKD’07) from August 24 to 27, 2007 in Haikou, Hainan, Ch...
This study explored the antioxidant potential and anti-fatigue effects of polyphenols extracted from Areca Catechu L. husk (AHP). Radicals scavenging activities and reducing power were determined to evaluate the antioxidant potentials in vitro and a weight loaded forced swimming test (WFST) was used to estimate the anti-fatigue effect. The main components of AHP were analyzed by HPCE at last. T...
Background, aim, and scope Atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) is one of the most widely used herbicides for broadleaf weed and certain annual grass controls and is popular because of its effectiveness and low cost. Losses of atrazine from agricultural lands into adjacent surface water and underlying groundwater have raised public concerns. Several computer models h...
Geographic information systems (GISS) were introduced into China (Mainland) in the 1970s. This paper provides an overview of the advances in GISs in Mainland China (not including Taiwan, Hong Kong, and Macau) during the past more than 20 years. It covers the developments of operational application systems, national geospatial databases, and technical systems. It also reviews the advances in res...
Wireless mesh network (WMN) is a key technology for supporting a variety of application scenarios. Recently, it evolves toward a multi-radio multi-channel (MR-MC) WMN architecture, which can improve network performance by equipping each node with multiple radio interfaces and by using multiple non-overlapping channels. This evolution poses new challenges on network design. Specifically, topolog...
