Information Security in Big Data: Privacy and Data Mining
TL;DR: This paper identifies four different types of users involved in data mining applications, namely, data provider, data collector, data miner, and decision maker, and examines various approaches that can help to protect sensitive information.
Journal ArticleDOI
Permissioned Blockchain and Edge Computing Empowered Privacy-Preserving Smart Grid Networks
TL;DR: This paper proposes a model permissioned blockchain edge model for smart grid network (PBEM-SGN) to address the two significant issues in smart grid, privacy protections, and energy security, by means of combining blockchain and edge computing techniques.
Journal ArticleDOI
Climate variation drives dengue dynamics
Lei Xu,Lei Xu,Leif Christian Stige,Kung-Sik Chan,Jie Zhou,Jun Yang,Shaowei Sang,Ming Wang,Zhicong Yang,Ziqiang Yan,Tong Jiang,Liang Lu,Yujuan Yue,Xiaobo Liu,Hualiang Lin,Jianguo Xu,Qiyong Liu,Qiyong Liu,Qiyong Liu,Nils Christian Stenseth +19 more
TL;DR: It is demonstrated that climate conditions, through the effects of rainfall and temperature on mosquito abundance and dengue transmission rate, play key roles in explaining the temporal dynamics of d Dengue incidence in the human population.
Journal ArticleDOI
Modification of the effects of air pollutants on mortality by temperature: A systematic review and meta-analysis
Jing Li,Alistair Woodward,Xiang-Yu Hou,Tong Zhu,Jinliang Zhang,Helen Brown,Jun Yang,Rennie Qin,Jinghong Gao,Shaohua Gu,Lei Xu,Xiaobo Liu,Qiyong Liu,Qiyong Liu +13 more
TL;DR: Interactions between high temperature and PM10 and O3 in the effects on non-accidental and cardiovascular mortality were observed: low temperature modified the effects of air pollutants but not in a consistent fashion: the effect of PM10 oncardiovascular mortality was diminished but the association between O3 and non- Accidental mortality was strengthened.

Climate-driven variation in mosquito density predicts the spatiotemporal dynamics of dengue
Ruiyun Li,Lei Xu,Lei Xu,Ottar N. Bjørnstad,Keke Liu,Keke Liu,Tie Song,Aifang Chen,Bing Xu,Qiyong Liu,Qiyong Liu,Nils Christian Stenseth,Nils Christian Stenseth +12 more
TL;DR: It is demonstrated that local weather conditions, through their impact on the variation of mosquito abundance, are a driver of dengue dynamics in China and illustrate that spatiotemporal dynamics of d Dengue are predictable from the local vector dynamics, which in turn can be predicted by climate conditions.
