1Ultrahigh performance concrete–properties, applications and perspectives显示文摘Over the last twenty years,remarkable advances have taken place in the research and application of ultra-high performance concrete(UHPC),which exhibits outstanding mechanical properties and excellent durability.It has shown great potential for the next generation infrastructure construction from the sustainability point of view.This paper will give an overview on UHPC,with particular focus on the properties,applications and perspectives.After several decades of development,several types of commercial UHPC materials are available in the market,and the properties of UHPC have been characterized by numerous experimental and field tests.Generally speaking,the performance(e.g.mechanical properties and durability)of UHPC is much better than normal concrete(NC)and high performance concrete(HPC).Therefore,the uses of UHPC are growing all over the world,in both fields of new construction and retrofitting.Nevertheless,it is still a special material and technology,which is not worldwide accepted.So some application prospects of UHPC are briefly introduced in the paper,and the efforts,which have to be made to turn UHPC into a widespread‘regular’technology,are discussed.This paper aims to help designers,engineers,architects and infrastructure owners to know the capacities of UHPC and thus to increase the applications of this material.GU Chun Ping YE Guang SUN Wei 2015Science China(Technological Sciences)2015,58,4:28
2Isolation and characterization of dengue virus serotype 2 from the large dengue outbreak in Guangdong, China in 2014显示文摘Dengue has been well recognized as a global public health threat,but only sporadic epidemics and imported cases were reported in recent decades in China.Since July 2014,an unexpected large dengue outbreak has occurred in Guangdong province,China,resulting in more than 40000 patients including six deaths.To clarify and characterize the causative agent of this outbreak,the acute phase serum from a patient diagnosed with severe dengue was subjected to virus isolation and high-throughput sequencing(HTS).Traditional real-time RT-PCR and HTS with Ion Torrent PGM detected the presence of dengue virus serotype 2(DENV-2).A clinical DENV-2 isolate GZ05/2014 was obtained by culturing the patient serum in mosquito C6/36 cells.The complete genome of GZ05/2014 was determined and deposited in Gen Bank under the access number KP012546.Phylogenetic analysis based on the complete envelope gene showed that the newly DENV-2 isolate belonged to Cosmopolitan genotype and clustered closely with other Guangdong strains isolated in the past decade.No amino acid mutations that are obviously known to increase virulence or replication were identified throughout the genome of GZ05/2014.The high homology of Guangdong DENV-2 strains indicated the possibility of establishment of local DENV-2 circulation in Guangdong,China.These results help clarify the origin of this epidemic and predict the future status of dengue in China.ZHAO Hui ZHAO Ling Zhai JIANG Tao LI Xiao Feng FAN Hang HONG Wen Xin ZHANG Yu ZHU Qin YE Qing TONG Yi Gang CAO Wu Chun ZHANG Fu Chun QIN Cheng Feng 2014Science China(Life Sciences)2014,57,12:21

4A New Soil Infiltration Technology for Decentralized Sewage Treatment:Two-Stage Anaerobic Tank and Soil Trench System显示文摘The low removal effciency of total nitrogen(TN) is one of the main disadvantages of traditional single stage subsurface infiltration system,which combines an anaerobic tank and a soil filter field.In this study,a full-scale,two-stage anaerobic tank and soil trench system was designed and operated to evaluate the feasibility and performances in treating sewage from a school campus for over a one-year monitoring period.The raw sewage was prepared and fed into the first anaerobic tank and second tank by 60% and 40%,respectively.This novel process could decrease chemical oxygen demand with the dichromate method by 89%-96%,suspended solids by 91%-97%,and total phosphorus by 91%-97%.The denitrification was satisfactory in the second stage soil trench,so the removals of TN as well as ammonia nitrogen(NH+4-N) reached 68%-75% and 96%-99%,respectively.It appeared that the removal effciency of TN in this two-stage anaerobic tank and soil trench system was more effective than that in the single stage soil infiltration system.The effuent met the discharge standard for the sewage treatment plant(GB18918-2002) of China.YE Chun HU Zhan-Bo KONG Hai-Nan WANG Xin-Ze HE Sheng-Bing 2008Pedosphere2008,18,3:14

6Abnormal Audit Fees and Audit Opinion–Further Evidence from China's Capital Market显示文摘The existing literature on audit opinion shopping provides inconsistent evidence on whether such shopping has any association with abnormal audit fees. In this paper, we hypothesize that firms engage in audit opinion shopping and pay an abnormal audit fee only when their degree of accounting quality is low. To examine the issue, we group firms on the basis of their change in return on assets(ROA), and show that abnormal audit fees improve audit opinions only among firms that engage local auditors and have a low degree of ROA, but report a large increase in ROA, especially when the ROA change is the result of abnormal accruals. We find no association between abnormal audit fees and audit opinion improvement for other firms.Zanchun Xie Chun Cai Jianming Ye 2010China Journal of Accounting Research2010,,Z1:9
7Indirect mineral carbonation of blast furnace slag with(NH4)2SO4 as a recyclable extractant显示文摘Large quantities of CO_2 and blast furnace slag are discharged in the iron and steel industry. Mineral carbonation of blast furnace slag can offer substantial CO_2 emission reduction and comprehensive utilisation of the solid waste. In this study, a recyclable extractant,(NH_4)_2SO_4, was used to extract calcium and magnesium from blast furnace slag(main phases of gehlenite and akermanite) by using low-temperature roasting to fix CO_2 through aqueous carbonation. The process parameters and efficiency of the roasting extraction, mineralisation, and Al recovery were investigated in detail. The results showed that the extractions of Ca, Mg, and Al can reach almost 100% at an(NH4)_2SO_4-to-slag mass ratio of 3:1 and at 370°C in 1 h. Adjusting the p H value of the leaching solution of the roasted slag to 5.5 with the NH_3 released during the roasting resulted in 99% Al precipitation, while co-precipitation of Mg was lower than 2%. The Mg-rich leachate after the depletion of Al and the leaching residue(main phases of CaSO_4 and SiO_2) were carbonated using(NH_4)_2CO_3 and NH_4HCO_3 solutions, respectively, under mild conditions. Approximately 99% of Ca and 89% of Mg in the blast furnace slag were converted into CaCO_3 and(NH_4)_2 Mg(CO_3)_2·4 H_2O,respectively. The latter can be selectively decomposed to magnesium carbonate at 100-200 °C to recover the NH_3 for reuse. In the present route, the total CO_2 sequestration capacity per tonne of blast furnace slag reached up to 316 kg, and 313 kg of Al-rich precipitate, 1000 kg of carbonated product containing CaCO_3 and SiO_2, and 304 kg of carbonated product containing calcium carbonate and magnesium carbonate were recovered simultaneously. These products can be used, respectively, as raw materials for the production of electrolytic aluminium, cement, and light magnesium carbonate to replace natural resources.Jinpeng Hu Weizao Liu Lin Wang Qiang Liu Fang Chen Hairong Yue Bin Liang Li Lü Ye Wang Guoquan Zhang Chun Li 2017Journal of Energy Chemistry2017,26,5:9

9Long-term joint effect of nutrients and temperature increase on algal growth in Lake Taihu,China显示文摘To study how global warming and eutrophication affect water ecosystems,a multiplicative growth Monod model,modified by incorporating the Arrhenius equation,was applied to Lake Taihu to quantitatively study the relationships between algal biomass and both nutrients and temperature using long-term data.To qualitatively assess which factor was a limitation of the improved model,temperature variables were calculated using annual mean air temperature (AT),water temperature (WT),and their average temperature (ST),while substrate variables were calculated using annual mean total nitrogen (TN),total phosphorus (TP),and their weighted aggregate (R),respectively.The nine fitted curves showed that TN and AT were two important factors influencing algal growth;AT limited growth as algal photosynthesis is mainly carried out near the water surface;N leakage of phytoplankton and internal phosphorus load from sediment explains why TN was the best predictor of peak biomass using the Monod model.The fitted results suggest that annual mean algal biomass increased by 0.145 times when annual mean AT increased by 1.0°C.Results also showed that the more eutrophic the lake,the greater the effect AT had on algal growth.Subsequently,the long-term joint effect of annual temperature increase and eutrophication to water ecosystems can be quantitatively assessed and predicted.Chun Ye Zhemin Shen Tao Zhang Maohong Fan Yangming Lei Jianda Zhang 2011Journal of Environmental Sciences2011,23,2:9
10Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 2020Biomedical and Environmental Sciences2020,33,12:8

12Research on carbon and oxygen isotopes in phosphorus-bearing rock series of the Late Neoproteroic-Early Cambrian Taozichong Formation in Qingzhen City, Guizhou Province, Southwest China显示文摘In the study of the phosphate-bearing stratum at the bottom of the Cambrian system, the authors found that there occurred carbon isotope negative anomalies in the Taozichong section phosphate-bearing stratum in Qingzhen, Guizhou Province; they can be correspondingly compared with other synsedimentary carbon isotope negative anomalies both at home and abroad. The results showed that there occurred three negative anomalies of carbon isotopes in the Neoproterozoic-Early Cambrian Taozichong Formation, indicating that the temporal palaeo-oceanographical environment changed significantly, in which there happened two times of intensive carbon isotope variation, corresponding to creature extinction. Meanwhile, it is believed that the carbon isotope negative anomalies in phosphorites were caused by the ascending water mass of ocean current with the negative carbon isotopic composition of deep-ocean hydrothermal deposits.MAO Tie YANG Ruidong MAO Jiaren YE Chun LIU Kun GAO Junbo 2014Chinese Journal Of Geochemistry2014,33,4:6
13An Anomalous Behavior Detection Model in Cloud Computing显示文摘This paper proposes an anomalous behavior detection model based on cloud computing. Virtual Machines(VMs) are one of the key components of cloud Infrastructure as a Service(Iaa S). The security of such VMs is critical to Iaa S security. Many studies have been done on cloud computing security issues, but research into VM security issues, especially regarding VM network traffic anomalous behavior detection, remains inadequate.More and more studies show that communication among internal nodes exhibits complex patterns. Communication among VMs in cloud computing is invisible. Researchers find such issues challenging, and few solutions have been proposed—leaving cloud computing vulnerable to network attacks. This paper proposes a model that uses Software-Defined Networks(SDN) to implement traffic redirection. Our model can capture inter-VM traffic, detect known and unknown anomalous network behaviors, adopt hybrid techniques to analyze VM network behaviors, and control network systems. The experimental results indicate that the effectiveness of our approach is greater than 90%, and prove the feasibility of the model.Xiaoming Ye Xingshu Chen Haizhou Wang Xuemei Zeng Guolin Shao Xueyuan Yin Chun Xu 2016Tsinghua Science and Technology2016,21,3:5
14Mesoporous silica rods with cone shaped pores modulate inflammation and deliver BMP-2 for bone regeneration显示文摘Biomaterials with suitable osteoimmunomodulation properties and ability to deliver osteoinductive biomolecules,such as bone morphogenetic proteins,are desired for bone regeneration.Herein,we report the development of mesoporous silica rods with large cone-shaped pores(MSR-CP)to load and deliver large protein drugs.It is noted that those cone-shaped pores on the surface modulated the immune response and reduced the pro-inflammatory reaction of stimulated macrophage.Furthermore,bone morphogenetic proteins 2(BMP-2)loaded MSR-CP facilitated osteogenic differentiation and promoted osteogenesis of bone marrow stromal cells.In vivo tests confirmed BMP-2 loaded MSR-CP improved the bone regeneration performance.This study provides a potential strategy for the design of drug delivery systems for bone regeneration.Chun Xu Lan Xiao Yuxue Cao Yan He Chang Lei Yin Xiao Wujin Sun Samad Ahadian Xueting Zhou Ali Khademhosseini Qingsong Ye 2020Nano Research2020,13,9:5
15Verticality Detection Algorithm Based on Local Image Sharpness Criterion显示文摘In the high precision image measurement system,the verticality error between the axis of the shooting system and the measured object can bring error of the measurement result.The high demand of the system’s vertical degree is raised by measure system due to the demands of high precision and disposable full field imaging in the micro-parts imaging measurement.The existing method of optical axis verticality detection cannot meet the demand all.In order to achieve the high-precision adjustment of the system optical axis,the algorithm of detecting verticality based on regional image definition is proposed.First,the objected standard image is divided into fixed area.Then,the object plane is moved from the downside to the upside of the focus plane,meanwhile,recording the definition function values of each standard image region at each step,and fitting out the clearest positions of the regions.Finally,according to the inter-regional relations between the locations and the height difference of the each regional clearest position,the small angle between the optical axis and the measured surface can be calculated.The experiment is based on the given image of lithography template with the scale of 10 μm as move unit,and the results show that this method effective reduced the small angle between the system optical axis and the measured body in high-precision image measuring system,the evaluation accuracy is less than 0.1°,meeting the requirements in high-precision measurement.The proposed method of detecting verticality based on regional image definition can evaluate the verticality error between the axis of the shooting system and the measured object accurately,effectively and conveniently.ZHANG Jin WANG Zhong YE Shenghua YANG Chun LI Lin 2012Chinese Journal of Mechanical Engineering2012,25,1:5
