8Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves显示文摘Metamaterials based on effective media can be used to produce a number of unusual physical properties(for example,negative refraction and invisibility cloaking)because they can be tailored with effective medium parameters that do not occur in nature.Recently,the use of coding metamaterials has been suggested for the control of electromagnetic waves through the design of coding sequences using digital elements‘0’and‘1,'which possess opposite phase responses.Here we propose the concept of an anisotropic coding metamaterial in which the coding behaviors in different directions are dependent on the polarization status of the electromagnetic waves.We experimentally demonstrate an ultrathin and flexible polarization-controlled anisotropic coding metasurface that functions in the terahertz regime using specially designed coding elements.By encoding the elements with elaborately designed coding sequences(both 1-bit and 2-bit sequences),the x-and y-polarized waves can be anomalously reflected or independently diffused in three dimensions.The simulated far-field scattering patterns and near-field distributions are presented to illustrate the dual-functional performance of the encoded metasurface,and the results are consistent with the measured results.We further demonstrate the ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions,thus providing powerful control of differently polarized electromagnetic waves.The proposed method enables versatile beam behaviors under orthogonal polarizations using a single metasurface and has the potential for use in the development of interesting terahertz devices.Shuo Liu Tie Jun Cui Quan Xu Di Bao Liangliang Du Xiang Wan Wen Xuan Tang Chunmei Ouyang Xiao Yang Zhou Hao Yuan Hui Feng Ma Wei Xiang Jiang Jiaguang Han Weili Zhang Qiang Cheng 2016Light(Science & Applications)2016,5,1:36
9Preliminary results pertaining to coseismic displacement and preseismic strain accumulation of the Lushan M_S7.0 earthquake,as reflected by GPS surveying显示文摘This paper presents the coseismic displacement and preseismic deformation fields of the Lushan MS7.0 earthquake that occurred on April 20,2013.The results are based on GPS observations along the Longmenshan fault and within its vicinity.The coseismic displacement and preseismic GPS results indicate that in the strain release of this earthquake,the thrust rupture is dominant and the laevorotation movement is secondary.Furthermore,we infer that any possible the rupture does not reach the earth’s surface,and the seismogenic fault is most likely one fault to the east of the Guanxian-Anxian fault.Some detailed results are obtainable.(1)The southern segment of the Longmenshan fault is locked preceding the Lushan earthquake.After the Wenchuan earthquake,the strain accumulation rate in the southeast direction accelerates in the epicenter of the Lushan earthquake,and the angle between the principal compressional strain and the seismogenic fault indicates that a sinistral deformation background in the direction of the seismogenic fault precedes the Lushan earthquake.Therefore,it is evident that the Wenchuan MS8.0 earthquake accelerated the pregnancy of the Lushan earthquake.(2)The coseismic displacements reflected by GPS data are mainly located in a region that is 230 km(NW direction)×100 km(SW direction),and coseismic displacements larger than 10 mm lie predominantly in a100-km region(NW direction).(3)On a large scale,the coseismic displacement shows thrust characteristics,but the associated values are remarkably small in the near field(within 70 km)of the earthquake fault.Meanwhile,the thrust movement in this70-km region does not correspond with the attenuation characteristics of the strain release,indicating that the rupture of this earthquake does not reach the earth’s surface.(4)The laevorotation movements are remarkable in the 50-km region,which is located in the hanging wall that is close to the earthquake fault,and the corresponding values in this case correlate with the attenuation characteristics of the strain release.WU YanQiang JIANG ZaiSen WANG Min CHE Shi LIAO Hua LI Qiang LI Peng YANG YongLin XIANG HePing SHAO ZhiGang WANG WuXing WEI WenXin LIU XiaoXia 2013Chinese Science Bulletin2013,58,28:33
10Magnetic resonance diffusion tensor imaging following major ozonated autohemotherapy for treatment of acute cerebral infarction显示文摘Major ozonated autohemotherapy has been shown to promote recovery of upper limb motor function in patients with acute cerebral infarction,but whether major ozonated autohemotherapy affects remote injury remains poorly understood.Here,we assumed that major ozonated autohemotherapy contributes to recovery of clinical function,possibly by reducing remote injury after acute cerebral infarction.Sixty acute cerebral infarction patients aged 30–80 years were equally and randomly allocated to ozone treatment and control groups.Patients in the ozone treatment group received medical treatment and major ozonated autohemotherapy(47 mg/L,100 m L ozone) for 10 ± 2 days.Patients in the control group received medical treatment only.National Institutes of Health Stroke Scale score,modified Rankin scale score,and reduced degree of fractional anisotropy values of brain magnetic resonance diffusion tensor imaging were remarkably decreased,brain function improved,clinical efficiency significantly increased,and no obvious adverse reactions detected in the ozone treatment group compared with the control group.These findings suggest that major ozonated autohemotherapy promotes recovery of neurological function in acute cerebral infarction patients by reducing remote injury,and additionally,exhibits high safety.Xiao-na Wu Tao Zhang Jun Wang Xiao-yan Liu Zhen-sheng Li Wei Xiang Wei-qing Du Hong-jun Yang Tie-gen Xiong Wen-ting Deng Kai-run Peng Su-yue Pan 2016Neural Regeneration Research2016,11,7:32
11Simultaneous Fe(Ⅲ) reduction and ammonia oxidation process in Anammox sludge显示文摘In recent years, there have been a number of reports on the phenomenon in which ferric iron(Fe(Ⅲ)) is reduced to ferrous iron [Fe(Ⅱ)] in anaerobic environments, accompanied by simultaneous oxidation of ammonia to NO2-, NO3-, or N2.However, studies on the relevant reaction characteristics and mechanisms are rare. Recently, in research on the effect of Fe(Ⅲ) on the activity of Anammox sludge, excess ammonia oxidization has also been found.Hence, in the present study, Fe(Ⅲ) was used to serve as the electron acceptor instead of NO2-,and the feasibility and characteristics of Anammox coupled to Fe(Ⅲ) reduction(termed Feammox) were investigated. After 160 days of cultivation, the conversion rate of ammonia in the reactor was above 80%, accompanied by the production of a large amount of NO3-and a small amount of NO2-. The total nitrogen removal rate was up to 71.8%. Furthermore,quantities of Fe(Ⅱ) were detected in the sludge fluorescence in situ hybridization(FISH) and denaturated gradient gel electrophoresis(DGGE) analyses further revealed that in the sludge, some Anammox bacteria were retained, and some microbes were enriched during the acclimatization process. We thus deduced that in Anammox sludge, Fe(Ⅲ) reduction takes place together with ammonia oxidation to NO2-and NO3-along with the Anammox process.Xiang Li Yong Huang Heng-wei Liu Chuan Wu Wei Bi Yi Yuan Xin Liu 2018Journal of Environmental Sciences2018,30,2:30

13Predictive value of the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score in the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure显示文摘Background:As a large,prospective,multicenter study-based prognostic score for hepatitis B virus-related acute-on-chronic liver failure(HBV-ACLF),the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score(COSSH-ACLFs),has been approved by some foreign scholars;however,its predictive value needs to be verified.This study investigated the predictive value of COSSH-ACLFs for short-term prognosis in Chinese patients with HBV-ACLF.Methods:This retrospective cohort study included 751 patients with HBV-ACLF admitted to the Fifth Medical Center of Chinese PLA General Hospital between January 2011 and December 2014.Spearman method was used to assess the correlation of COSSHACLFs with classical scores.Different COX multivariate regression models were used to confirm the relationship between COSSHACLFs and short-term prognosis in patients with HBV-ACLF,and stratified analysis was used to further verify the stability of this relationship.We compared the predictive powers of COSSH-ACLFs and other classical scores using area under the receiver operating characteristic curve(AUROC)and Z-test.Results:A total of 975 patients with HBV-ACLF were screened,and 751 were analyzed(623 male and 128 female).COSSH-ACLFs was the highest in patients with end-stage ACLF,followed by those with middle-and early-stage ACLF(H=211.8,P<0.001).In the fully adjusted model,COX multivariate regression analysis revealed that COSSH-ACLFs(as a continuous variable)was independently and positively correlated with mortality risk in patients with HBV-ACLF at 28 days(hazard ratio[HR]:1.37[1.22,1.53],P<0.001)and 90 days(HR:1.43[1.29,1.58],P<0.001).The same trend could be observed in the crude model and minimally adjusted model.The AUROCs of COSSH-ACLFs for 28-day and 90-day prognoses in patients with HBV-ACLF were 0.807 and 0.792,respectively,indicating a stronger predictive accuracy than those of classic models.Conclusions:COSSH-ACLFs,with a superior predictive accuracy compared with other classical scores,can strongly predict shortterm prognosis in Chinese patients with HBV-ACLF.Jing-Jing Tong Wei Zhao Xiu-Ying Mu Xiang Xu Hai-Bin Su Xiao-Yan Liu Jing Chen Xing-Ran Zhai Yu Wang Jin-Hua Hu 2019Chinese Medical Journal2019,,13:27
14High entropy defective fluorite structured rare-earth niobates and tantalates for thermal barrier applications显示文摘Rare-earth tantalates and niobates(REjTaO7 and REjNbO7)have been considered as promising candidate thermal barrier coating(TBC)materials in next generation gas-turbine engines due to their ultra-low thermal conductivity and better thermal stability than yttria-stabilized zirconia(YSZ).However,the low Vickers hardness and toughness are the main shortcomings of RE;TaO-and REjNbOr that limit their applications as TBC materials.To increase the hardness,high entropy(Yu3Ybu3Er/3)sTaOr,(Y13YbnErns)NbO,and(Sm1/6Eu1/6Y 1/6Yb1/6Lu1/6Er1/6)3(Nb1/2Ta1/2)O7 are designed and synthesized in this study.These high entropy ceramics exhibit high Vickers hardness(10.912.0 GPa),close thermal expansion coefficients to that of single-principal-component RE3TaO,and RE;NbO,(7.9×10^-6-10.8×10-6 C-1 at room temperature),good phase stability,and good chemical compatibility with thermally grown Al2O3,which make them promising for applications as candidate TBC materials.Zifan ZHAO Heng CHEN Huimin XIANG Fu-Zhi DAI Xiaohui WANG Wei XU Kuang SUN Zhjjian PENG Yanchun ZHOU 2020Journal of Advanced Ceramics2020,9,3:27
15Economic burden of irritable bowel syndrome in China显示文摘AIM To estimate annual direct and indirect costs for patients diagnosed with irritable bowel syndrome(IBS) and subtypes.METHODS Patients completed a standardized questionnaire concerning usage of healthcare resources, travel costs, meals, and productivity loss of patients when seeking treatment for IBS. Total annual costs per patient were calculated as the sum of direct(including medical and nonmedical) and indirect costs. Total annual costs per patient among various IBS subtypes were compared. Analysis of variance and bootstrapped independent sample t-tests were performed to determine differences between groups after controlling for IBS subtypes.RESULTS A total of 105 IBS patients(64.80% female), mean age of 57.12 years ± 10.31 years), mean disease duration of 4.31 years ± 5.40 years, were included. Total annual costs per patient were estimated as CNy18262.84(USD2933.08). Inpatient and outpatient healthcare use were major cost drivers, accounting for 46.41%and 23.36% of total annual costs, respectively. Productivity loss accounted for 25.32% of total annual costs. The proportions of direct and indirect costs were similarto published studies in other countries. Nationally, the total costs of managing IBS would amount to CNy123.83 billion(USD1.99 billion). Among the IBS subtypes, total annual costs per patient of IBS-M was highest at CNy18891.18(USD3034). Furthermore, there was significant difference in productivity loss among IBS subtypes(P = 0.031).CONCLUSION IBS imposes a huge economic burden on patients and healthcare systems, which could account for 3.3% of the total healthcare budget for the entire Chinese nation. More than two-thirds of total annual costs of IBS consist of inpatient and outpatient healthcare use. Among the subtypes, IBS-M patients appear to have the greatest economic burden but require further confirmation.Fang Zhang Wei Xiang Chun-yan Li Shu-Chuen Li 2016World Journal of Gastroenterology2016,22,47:28

18ECCM scheme against interrupted sampling repeater jammer based on time-frequency analysis显示文摘The interrupted sampling repeater jamming(ISRJ) is an effective deception jamming method for coherent radar, especially for the wideband linear frequency modulation(LFM) radar. An electronic counter-countermeasure(ECCM) scheme is proposed to remove the ISRJ-based false targets from the pulse compression result of the de-chirping radar. Through the time-frequency(TF) analysis of the radar echo signal, it can be found that the TF characteristics of the ISRJ signal are discontinuous in the pulse duration because the ISRJ jammer needs short durations to receive the radar signal. Based on the discontinuous characteristics a particular band-pass filter can be generated by two alternative approaches to retain the true target signal and suppress the ISRJ signal. The simulation results prove the validity of the proposed ECCM scheme for the ISRJ.Shixian Gong Xizhang Wei Xiang Li 2014Journal of Systems Engineering and Electronics2014,25,6:24
19Simultaneous oxidation of NO,SO_2 and Hg^0 from flue gas by pulsed corona discharge显示文摘A process capable of simultaneously oxidizing NO,SO2,and Hg0 was proposed,using a high-voltage and short-duration positive pulsed corona discharge.By focusing on NO,SO2,and Hg0 oxidation effciencies,the influences of pulse peak voltage,pulse frequency,initial concentration,electrode number,residence time and water vapor addition were investigated.The results indicate that NO,SO2 and Hg0 oxidation effciencies depend primarily on the radicals(OH,HO2,O) and the active species(O3,H2O2,etc.) produced by the pulsed corona discharge.The NO,SO2 and Hg0 oxidation effciencies could be improved as pulse peak voltage,pulse frequency,electrode number and residence time increased,but they were reduced with increasing initial concentrations.By adding water vapor,the SO2 oxidation effciency was improved remarkably,while the NO oxidation effciency decreased slightly.In our experiments,the simultaneous NO,SO2,and Hg0 oxidation effciencies reached to 40%,98%,and 55% with the initial concentrations 479 mg/m3,1040 mg/m3,and 15.0 μg/m3,respectively.XU Fei,LUO Zhongyang,CAO Wei,WANG Peng,WEI Bo,GAO Xiang,FANG Mengxiang,CEN Kefa State key Laboratory of Clean Energy Utilization,Zhejiang University,Hangzhou 310027,China. 2009Journal of Environmental Sciences2009,21,3:22
