The application of prefabricated bridge structures is great significance to building industrialization, which can realize the green construction and maintenance process low energy consumption emission as well normal operation transportation in time, effectively development requirements. However, substructure a conventional usually needs cast bearing platform between pier column, may not give fu...

BACKGROUND Type-specific high-risk HPV (hrHPV) infection is related to cervical carcinogenesis. The prevalence of hrHPV infection varies geographically, which might reflect the epidemiological characteristics of cervical cancer among different populations. To establish a foundation for HPV-based screening and vaccination programs in China, we investigated the most recent HPV prevalence and geno...

BACKGROUND Season of birth (SoB) has been linked with various health outcomes. This study aimed to examine the associations between month of birth (MoB) and adult measures of leg length (LL), body mass index (BMI), and waist circumference (WC). METHODS We analysed survey data from 10 geographically diverse areas of China obtained through the China Kadoorie Biobank. Analysis included 487 529 a...

Wetland cities were proposed by the International Convention Organization for protection of urban wetlands. Few studies have performed land cover classifications internationally recognized wetland or explored what contribution classification results can make to establishment additional date. Based on Sentinel-1 and 2 data, this study used a 10-fold random forest method classify first six in Chi...

BACKGROUND The one-step method was routine practices in China, scientific evidence to support this intervention is scarce. The purpose of this study was to observe the natural process of head-to-body delivery interval by waiting for at least one contraction (two-step) after head delivered in normal birth. METHODS From March 1 to March 30 in 2015 at Haikou Maternal and Child Hospital in China,...

Purpose: To investigate the clinical efficacy of anti-programmed cell death-1 (PD-1) immunotherapy in combination with chemotherapy patients suffering from locally advanced non-small lung cancer (NSCLC).
 Methods: A total 110 NSCLC admitted The Second Affiliated Hospital Hainan Medical University, Haikou, China were randomly divided into two groups using envelope method. control group was ...

• A mathematical modelling approach is proposed to predict the matching probability and expected ride/shared distance of each ridepooling order. The model explains complex mechanism that determines OD pair. generates fairly good predictions under diverse conditions demand intensities. popularity smartphones advent GPS positioning wireless communication technologies in recent decade have facilit...

Temperature inversions inhibit the transfer of momentum, heat and moisture in atmosphere have led to severe air pollution China. This study investigated spatiotemporal variation temperature China using sounding data for past four decades. Surface-based inversion, elevated both one dataset were analysed. Statistical analyses inversion parameters included frequency, strength depth. The annual fre...

Air pollution over coastal port areas has become a major concern of today's world. As one the largest shipping countries, China issued series emission control policies to regulate air in these areas. This study investigated effectiveness by exploring spatiotemporal variations NO2 and SO2 five clusters i.e., Bohai Rim Area (BRA), Yangtze River Delta (YRD), Pearl (PRD), Southeast Coast (SEC) Sout...
