Pollution in P2P file sharing occurs when a large number of decoy files are injected into the P2P system. Since peers “serve” each other in the P2P file sharing system, it is obvious that pollution dynamics are closely related to user behavior. Therefore, we first conduct a human subject study to investigate user behavior. We identify the factors that are key to model user behavior, e.g., coope...
Freeways were originally conceived to provide virtually unlimited mobility to road users. However, the continuous increase in car ownership and demand has led to a steady increase (in space and time) of recurrent and nonrecurrent freeway congestion, particularly within and around metropolitan areas. Freeway congestion causes excessive delays, increases fuel consumption and environmental polluti...

The microbial faecal pollution of rivers has wide-ranging impacts on a variety of human activities that rely on appropriate river water quality. Thus, detailed knowledge of the extent and origin of microbial faecal pollution is crucial for watershed management activities to maintain safe water use. In this study, the microbial faecal pollution levels were monitored by standard faecal indicator ...
Multivariate statistical methods including cluster analysis (CA), discriminant analysis (DA) and component analysis/factor analysis (PCA/FA), were applied to explore the surface water quality datasets including 14 parameters at 28 sites of the Eastern Poyang Lake Basin, Jiangxi Province of China, from January 2012 to April 2015, characterize spatiotemporal variation in pollution and identify po...
BACKGROUND Poverty is a major determinant of population health, but little is known about its role in modifying air pollution effects. OBJECTIVES We set out to examine whether people residing in socially deprived communities are at higher mortality risk from ambient air pollution. METHODS This study included 209 tertiary planning units (TPUs), the smallest units for town planning in the Spe...
BACKGROUND Exposure to particulate matter air pollution (PM) has been associated with cardiovascular diseases. OBJECTIVES In this study we evaluated whether annual exposure to ambient air pollution is associated with systemic inflammation, which is hypothesized to be an intermediate step to cardiovascular disease. METHODS Six cohorts of adults from Central and Northern Europe were used in t...
Objectives Environmental pollution is a significant global issue. Both objective (scientifically measured) environmental pollution and perceived levels of pollution are important predictors of self-reported health. The purpose of this study was to compare the associations between perceived environmental pollution and health in China, Japan, and South Korea. Methods Data were obtained from the...

Urban canals play a major socio-economic role in many tropical countries and, particularly, Thailand. One of the overlooked functions that they perform is a significant attenuation of waste-related pathogens posing considerable health risk, as well as pollution attenuation in general. The study dealt with a comparison of three canals receiving: (i) municipal, (ii) mainly industrial and (iii) ma...
