Pay as How Well You Do: A Quality Based Incentive Mechanism for Crowdsensing
We incorporate the consideration of data quality into the design of incentive mechanism for crowdsensing, and propose to pay the participants as how well they do, to motivate the rational participants to perform data sensing efficiently. Expand

The attributable risk of chronic obstructive pulmonary disease due to ambient fine particulate pollution among older adults.
BACKGROUND The linkage between ambient fine particle pollution (PM2.5) and chronic obstructive pulmonary disease (COPD) and the attributable risk remained largely unknown. This study determined the… Expand
The impact of multimorbidity on adult physical and mental health in low- and middle-income countries: what does the study on global ageing and adult health (SAGE) reveal?
BackgroundChronic diseases contribute a large share of disease burden in low- and middle-income countries (LMICs). Chronic diseases have a tendency to occur simultaneously and where there are two or… Expand
