Journal ArticleDOI
Comparative studies of metamodelling techniques under multiple modelling criteria
TL;DR: This paper systematically compare four popular metamodelling techniques – polynomial regression, multivariate adaptive regression splines, radial basis functions, and kriging – based on multiple performance criteria using fourteen test problems representing different classes of problems.
Journal ArticleDOI
Sequential Optimization and Reliability Assessment Method for Efficient Probabilistic Design
Xiaoping Du,Wei Chen +1 more
TL;DR: The sequential optimization and reliability assessment (SORA) as mentioned in this paper method employs a single-loop strategy, where a serial of cycles of optimization and assessment is employed, and the reliability assessment is decoupled from each other.
Journal ArticleDOI
Porous graphitic carbon nitride synthesized via direct polymerization of urea for efficient sunlight-driven photocatalytic hydrogen production
TL;DR: Low cost and environmentally benign urea was used to synthesize the metal-free photocatalyst graphitic carbon nitride (g-C₃N₄), and a porous structure with increased BET surface area and pore volume shows a much higher hydrogen production rate under simulated sunlight irradiation.
Journal ArticleDOI
Hydroxychloroquine in patients with mainly mild to moderate coronavirus disease 2019: open label, randomised controlled trial.
Wei Tang,Zhujun Cao,Mingfeng Han,Zhengyan Wang,Junwen Chen,Wenjin Sun,Yaojie Wu,Wei Xiao,Shengyong Liu,Erzhen Chen,Wei Chen,Xiongbiao Wang,Jiuyong Yang,Jun Lin,Qingxia Zhao,Youqin Yan,Zhibin Xie,Dan Li,Yaofeng Yang,Leshan Liu,Jieming Qu,Guang Ning,Guochao Shi,Qing Xie +23 more
TL;DR: Administration of hydroxychloroquine did not result in a significantly higher probability of negative conversion than standard of care alone in patients admitted to hospital with mainly persistent mild to moderate covid-19, and adverse events were higher in hydroxy chloroquine recipients than in non-recipients.
Journal ArticleDOI
Nitrogen-doped carbon quantum dots: facile synthesis and application as a "turn-off" fluorescent probe for detection of Hg2+ ions.
Ruizhong Zhang,Wei Chen +1 more
TL;DR: The selectivity experiments reveal that the fluorescent sensor is specific for Hg(2+) even with interference by high concentrations of other metal ions, and can be successfully applied to the determination of Hg (2+) in tap water and real lake water samples.
