6Research on Flexural Behavior of Coral Aggregate Reinforced Concrete Beams显示文摘Through the flexural behavior test of coral aggregate reinforced concrete beams(CARCB) and ordinary Portland reinforced concrete beams(OPRCB), and based on the parameters of concrete types, concrete strength grades and reinforcement ratios, the crack development, failure mode, midspan deflection and flexural capacity were studied, the relationships of bending moment-midspan deflection, load-longitudinal tensile reinforcement strain, load-maximum crack width were established, and a calculation model for the flexural capacity of CARCB was suggested. The results showed that with the increase in the reinforcement ratio and concrete strength grade, the crack bending moment(Mcr)and ultimate bending moment(Mu) of CARCB gradually increased. The characteristics of CARCB and OPRCB are basically the same. Furthermore, through increasing the concrete strength grade and reinforcement ratio, Mcr/Mu could be increased to delay the cracking of CARCB. As the load increased, crack width(w) would also increase. At the beginning of the loading, w increased slowly. And then it increased rapidly when the load reached to the ultimate load, which then led to beam failure. Meanwhile, with a comprehensive consideration of the effects of steel corrosion on the loss of steel section and the decrease of steel yield strength, a more reasonable calculation model for the flexural capacity of CARCB was proposed.MA Hai-yan DA Bo YU Hong-fa WU Zhang-yu 2018China Ocean Engineering2018,32,5:8

10Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets.Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo 2021World Journal of Clinical Oncology2021,12,10:5
11A refutation of reported Levallois technology from Guanyindong Cave in south China显示文摘As one of the most complex forms of lithic technology known for the Paleolithic,research on the Levallois stoneknapping method is critically relevant to our understanding of the cognitive abilities and depth of planning capabilities of archaic hominins;as well as the diffusion of knowledge and social learning in Pleistocene societies.For decades,Levallois technology was thought to be absent from East Asia for much of the Pleistocene,appearing only quite late(ca.50-40 ka BP)[1,2].In a recent paper,H u et al.claim that Levallois technology was present at the Guanyindong(GYD)site in Qianxi County,Guizhou,Province,South China by at least 170 ka BP[3].This report claims that the GYD site is an exceptional case,preserving evidence of Levallois technology earlier than 50 ka BP.Feng Li Yinghua Li Xing Gao Steven L.Kuhn Eric Boёda John W.Olsen 2019National Science Review2019,6,6:4
12Anti-cyclic citrullinated peptide antibody predicts the development of rheumatoid arthritis in patients with undifferentiated arthritis显示文摘Background:Clinical outcomes of undifferentiated arthritis(UA)are diverse,and only 40%of patients with UA develop rheumatoid arthritis(RA)after 3 years.Discovering predictive markers at disease onset for further intervention is critical.Therefore,our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.Methods:We performed a prospective,multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals.Clinical and serological parameters were obtained at recruitment.Follow-up was undertaken in all patients every 12 weeks for 2 years.Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.Results:A total of 234 patients were recruited in this study,and 17(7.3%)patients failed to follow up during the study.Among the 217 patients who completed the study,83(38.2%)patients went into remission.UA patients who developed RA had a higher rheumatoid factor(RF)-positivity(42.9%vs.16.8%,χ^2=8.228,P=0.008),anti-cyclic citrullinated peptide(CCP)antibodypositivity(66.7%vs.10.7%,χ^2=43.897,P<0.001),and double-positivity rate of RF and anti-CCP antibody(38.1%vs.4.1%,χ^2=32.131,P<0.001)than those who did not.Anti-CCP antibody but not RF was an independent predictor for RA development(hazard ratio 18.017,95%confidence interval:5.803–55.938;P<0.001).Conclusion:As an independent predictor of RA,anti-CCP antibody should be tested at disease onset in all patients with UA.Chun Li Yan Zhang Hui Song Jie Gao Dong-Bao Zhao Qi Zhu Dong-Yi He Li Wang Xiang-Pei Li Xu-Dong Liu Wei-Guo Xiao Xin-Yu Wu Hua-Xiang Wu Wei Tu Shao-Xian Hu Xin Wang Zhi-Jun Li Zhi-Min Lu Zhan-Yun Da Bo Liang Xiao-Min Liu Jin-Wei Zhao Ling Li Feng Han Wu-Fang Qi Wei Wei Xu Ma Zhen-Bin Li Gui-Min Zheng Feng-Xiao Zhang Yi Li You-Lian Wang Guang-Hui Ling Jin-Wei Chen Xiao-Qiang Hou Jing Zhang Qing-Ping Chen Chang-Lian Liu Yan Zhang Jia-Shun Zeng Qing-Hua Zou Yong-Fei Fang Yin Su Zhan-Guo Li 2019Chinese Medical Journal2019,,24:4

14Hepatic encephalopathy complicated with hyponatremia and acid-base disturbance and its prognosis显示文摘Objective:To improve the diagnosis and therapeutic effect of occurrence and development of hyponatremia and disorder of acid-base balance among patients with hepatic encephalopathy(HE) by elucidating the regularity and mechanism,as well as its influence on prognosis.Methods:327 HE patients admitted to our hospital from January 1990 to June 2010 were enrolled.Meanwhile 316 patients hospitalized in the medical department of the same hospital were chosen as the control group.Patients in both groups were given the same methods to measure arterial blood gas parameters(pH value,PaCO2,[HCO3-],TCO2,BE and SaO2),blood biochemistry([Na+],[K+],[Cl-]),liver function,kidney function and blood glucose,serum sodium,and thereupon tocalculate the anion gap(AG) and the potential [HCO3-],and acid-base balance disorder.Results:Among the 327 HE patients,hyponatremia was found in 188 cases(57.4%),of whom 132 patients died(70.2%).While among the 316 patients in control group,68 presented with hyponatremia(21.5%),and 19 died(27.9%).The incidence and mortality were significantly different between the two groups(P<0.001).All the 327 patients presented with different degrees of acid-base balance disorder and 178 died(54.4%),in whom 164(50.2%) belonged to simple acid-base balance disorder and 74(45.1%) died,136(41.6%) were dual acid-base balance disorder and 80(58.8%) died,27(8.2%) were triple acid-base disturbance and 24(88.9%) died.Whereas in the control group only 83 patients(26.2%) were recognized as simple and dual acid-base balance disorder,and 18(21.7%) died.There was higher incidence of acid-base balance disorder and mortality rate in HE group than control one(P<0.001).Conclusion:Hyponatremia is valuable to judge HE patients' prognosis.The key parameters in the judgment and evaluation on acid-base balance disorder among HE patients are the change of pH values and serum electrolyte values.When pH value ≤ 7.30 or > 7.55,it generally suggests a poor prognosis.Ren Chengshan Wang Lei Zhao Xiaoyan Yang Shiming Zhang Yanqi Wang Xiwen Bo Jianying Zhang Pengbin Guo Hong Ling Xianlong Li Yihui Da Siping Xie Xia Ren Wei Li Chunhua Qian Guisheng 2012Journal of Medical Colleges of PLA(China)2012,27,3:3
15High-throughput screening and machine learning for the efficient growth of high-quality single-wall carbon nanotubes显示文摘It has been a great challenge to optimize the growth conditions toward structure-controlled growth of single-wall carbon nanotubes(SWCNTs).Here,a high-throughput method combined with machine learning is reported that efficiently screens the growth conditions for the synthesis of high-quality SWCNTs.Patterned cobalt(Co)nanoparticles were deposited on a numerically marked silicon wafer as catalysts,and parameters of temperature,reduction time and carbon precursor were optimized.The crystallinity of the SWCNTs was characterized by Raman spectroscopy where the featured G/D peak intensity(IG/ID)was extracted automatically and mapped to the growth parameters to build a database.1,280 data were collected to train machine learning models.Random forest regression(RFR)showed high precision in predicting the growth conditions for high-quality SWCNTs,as validated by further chemical vapor deposition(CVD)growth.This method shows great potential in structure-controlled growth of SWCNTs.Zhong-Hai Ji Lili Zhang Dai-Ming Tang Chien-Ming Chen Torbjörn EMNordling Zheng-De Zhang Cui-Lan Ren Bo Da Xin Li Shu-Yu Guo Chang Liu Hui-Ming Cheng 2021Nano Research2021,14,12:3
16A New Anti-Collision Algorithm for Multi-Target Real Time Recognitionin RFID System显示文摘The problem of how to distinguish and recognize more than one target when they are entering the working area of the Radio Frequency Identification( RFID ) system should be considered in design of the system. To avoid signal interference with each other among all targets, an anti collision algorithm as well as the condition of working stability is proposed. The computer simulation shows that the new algorithm will be of advantages in the process of system design.SHEN Yu chao, WANG Hai bo, SHEN Shu qun, XU Da xiong (School of Electronic Engineering,Beijing University of Posts and Telecommunications,Beijing 100876,P.R.China) 2000The Journal of China Universities of Posts and Telecommunications2000,7,3:3
17Effect of Carbonation and Drying-Wetting Cycles on Chloride Diffusion Behavior of Coral Aggregate Seawater Concrete显示文摘Based on seawater immersion,drying-wetting cycles,carbonation and drying-wetting cycles for coral aggregate sea-water concrete(CASC)with different strength grades,the effect of carbonation and drying-wetting cycles on chloride diffusion be-havior of CASC is studied.The results show that the free surface chloride concentration(Cs),free chloride diffusion coefficient(Df)and time-dependent index(m)of CASC in the drying-wetting cycles is obviously higher than that in seawater immersion.The Df and m of CASC of carbonation and drying-wetting cycles is higher than that in the drying-wetting cycles.Carbonation increases the Df and m of CASC,which is against CASC to resist chloride corrosion.The corrosion possibility of CASC structures in different ex-posed areas is as follows:splash zone(carbonation and drying-wetting cycles)>tidal zone(drying-wetting cycles)>underwater zone(seawater immersion).Besides,the chloride diffusion rate of C65-CASC is 17.8%-63.4%higher than that of C65-ordinary aggre-gate concrete(OAC)in seawater immersion(underwater zone).Therefore,anti-corrosion measures should be adopted to improve the service life of CASC structure in the oceanic environment.DA Bo LI Yipeng YU Hongfa MA Haiyan CHEN Haoyu DOU Xuemei WU Zhangyu 2022Journal of Ocean University of China2022,21,1:2
