1Anisotropic 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
2Seasonal variation in surface ozone and its regional characteristics at global atmosphere watch stations in China显示文摘We investigated the seasonal and spatial ozone variations in China by using three-year surface ozone observation data from the six Chinese Global Atmosphere Watch(GAW)stations and tropospheric column ozone data from satellite retrieval over the period2010–2012. It is shown that the seasonal ozone variations at these GAW stations are rather different, particularly between the western and eastern locations. Compared with western China, eastern China has lower background ozone levels. However, the Asian summer monsoon(ASM) can transport photochemical pollutants from the southern to the northern areas in eastern China, leading to a northward gradual enhancement of background ozone levels at the eastern GAW stations. Over China, the tropospheric column ozone densities peak during spring and summer in the areas that are directly and/or indirectly affected by the ASM, and the peak time lags from the south to the north in eastern China. We also investigated the regional representativeness of seasonal variations of ozone at the six Chinese GAW stations using the yearly maximum tropospheric column month as indicator.The results show that the seasonal variation characteristics of ozone revealed by the Chinese GAW stations are typical, with each station having a considerable large surrounding area with the ozone maximum occurring at the same month. Ozone variations at the GAW stations are influenced by many complex factors and their regional representativeness needs to be investigated further in a broader sense.Ningwei Liu Weili Lin Jianzhong Ma Wanyun Xu Xiaobin Xu 2019Journal of Environmental Sciences2019,31,3:23
3Neuroprotective effect of ethyl acetate extract from gastrodia elata against transient focal cerebral ischemia in rats induced by middle cerebral artery occlusion显示文摘OBJECTIVE: To investigate the protective effect of neuroprotection against transient focal cerebral ischemia of the extract from Tianma(Rhizoma Gastrodiae) and the possible mechanisms underlying the action.METHODS: Cerebral ischemia-reperfusion injury was induced through middle cerebral artery occlusion(MCAO). Adult male Sprague-Dawley rats were randomly divided into four groups: sham-operated,ischemia-reperfusion model, 102.6 mg/kg extract treated and 11.4 mg/kg extract treated groups. The extract was prepared from gastrodia elata with ethyl acetate. The effect of the extract tested on rat neurological de fi cits and Cerebral index, cerebral infarct volume, brain injury, terminal dexynucleotidyl transferase-mediated d UTP nick end labeling(TUNEL) and B-cell lymphoma-2(Bcl-2) positive cells.RESULTS: The extract was able to reduce neurological scores, cerebral index and cerebral infarction rate. The brain injury was also relieved by the extract. The results of immunofluorescence staining analysis indicated that the extract increased the expression of Bcl-2 and reduced TUNEL-positive cells significantly in the extract treated groups.CONCLUSION: These results suggested that the extract relieved ischemic injury induced by transient focal cerebral ischemia in rats, and this neuroprotective effect might be partially due to the attenuated apoptosis pathway.Duan Xiaohua Wang Weili Liu Xiaoqing Yan Hanwen Dai Rong Lin Qing 2015Journal of Traditional Chinese Medicine2015,35,6:18
4Sulfur-based autotrophic denitrification from the micro-polluted water显示文摘Eutrophication caused by high concentrations of nutrients is a huge problem for many natural lakes and reservoirs. Removing the nitrogen contamination from the low C/N water body has become an urgent need. Autotrophic denitrification with the sulfur compound as electron donor was investigated in the biofilter reactors. Through the lab-scale experiment,it was found that different sulfur compounds and different carriers caused very different treatment performances. Thiosulfate was selected to be the best electron donor and ceramsite was chosen as the suitable carrier due to the good denitrification efficiency, low cost and the good resistibility against the high hydraulic loads. Later the optimum running parameters of the process were determined. Then the pilot-scale experiment was carried out with the real micro-polluted water from the West Lake, China. The results indicated that the autotrophic denitrification with thiosulfate as electron donor was feasible and applicable for the micro-polluted lake water.Weili Zhou Xu Liu Xiaojing Dong Zheng Wang Ying Yuan Hui Wang Shengbing He 2016Journal of Environmental Sciences2016,28,6:18
5Beclin 1 cleavage by caspase-3 inactivates autophagy and promotes apoptosis显示文摘Autophagy and apoptosis are both highly regulated biological processes that play essential roles in tissue homeostasis,development and diseases.Autophagy is also described as a mechanism of death pathways,however,the precise mechanism of how autophagy links to cell death remains to be fully understood.Beclin 1 is a dual regulator for both autophagy and apoptosis.In this study we found that Beclin 1 was a substrate of caspase-3 with two cleavage sites at positions 124 and 149,respectively.Furthermore,the autophagosome formation occurred,followed by the appearance of morphological hallmarks of apoptosis after staurosporine treatment.The cleavage products of Beclin 1 reduced autophagy and promoted apoptosis in HeLa cells and the cells in which Beclin 1 was stably knocked down by specific shRNA.In addition,the cleavage of Beclin 1 resulted in abrogating the interaction between Bcl-2 with Beclin 1,which could be blocked by z-VAD-fmk.Thus,our results suggest that the cleavage of Beclin 1 by caspase-3 may contribute to inactivate autophagy leading towards augmented apoptosis.Yushan Zhu Lixia Zhao Lei Liu Ping Gao Weili Tian Xiaohui Wang Haijing Jin Haidong Xu Quan Chen 2010Protein & Cell2010,1,5:17
6MiR-30a Positively Regulates the Inflammatory Response of Microglia in Experimental Autoimmune Encephalomyelitis显示文摘Multiple sclerosis(MS) is a classical inflammatory demyelinating disease of the central nervous system(CNS). Microglia are the main resident immune cells in the CNS and are closely associated with the pathogenesis of MS.In the present study, we found that mi R-30 a was highly expressed in jellyfish-like microglia in chronic active lesions of MS patients, as well as in the microglia of mice with experimental autoimmune encephalomyelitis(EAE) at the chronic phase. In vitro, the conditioned supernatant of mouse microglia overexpressing miR-30 a promoted the apoptosis of oligodendrocyte precursor cells(OPCs), and inhibited OPC differentiation. In vivo, overexpressing miR-30 a in transplanted microglia exacerbated the progression of EAE.Overexpression and knock-down experiments in primary cultured mouse microglia showed that mi R-30 a increased the expression of IL-1 b and i NOS, which are pro-inflammatory, while inhibiting the expression of Ym-1 and CD206.Mechanistically, mi R-30 a inhibited the expression of Ppargc1 b, which is the co-activator of peroxisome proliferator-activated receptor gamma, resulting in pro-inflammatory effects. Our work shows that mi R-30 a is an important regulator of the inflammatory response in microglia, and may be a promising therapeutic target for inflammatory diseases like MS in the CNS.Xue Fang Dingya Sun Zhihong Wang Zhongwang Yu Weili Liu Yingyan Pu Dan Wang Aijun Huang Mingdong Liu Zhenghua Xiang Cheng He Li Cao 2017Neuroscience Bulletin2017,33,6:16
7Characteristics and recent trends of sulfur dioxide at urban,rural,and background sites in North China:Effectiveness of control measures显示文摘SO 2 measurements made in recent years at sites in Beijing and its surrounding areas are performed to study the variations and trends of surface SO 2 at different types of sites in Northern China.The overall average concentrations of SO 2 are (16.8±13.1) ppb,(14.8±9.4) ppb,and (7.5±4.0) ppb at China Meteorological Administration (CMA,Beijing urban area),Gucheng (GCH,relatively polluted rural area,110 km to the southwest of Beijing urban area),and Shangdianzi (SDZ,clean background area,100 km to the northeast of Beijing urban area),respectively.The SO 2 levels in winter (heating season) are 4-6 folds higher than those in summer.There are highly significant correlations among the daily means of SO 2 at different sites,indicating regional characteristics of SO 2 pollution.Diurnal patterns of surface SO 2 at all sites have a common feature with a daytime peak,which is probably caused by the downward mixing and/or the advection transport of SO 2 -richer air over the North China Plain.The concentrations of SO 2 at CMA and GCH show highly significant downward trends (-4.4 ppb/yr for CMA and -2.4 ppb/yr for GCH),while a less significant trend (-0.3 ppb/yr) is identified in the data from SDZ,reflecting the character of SDZ as a regional atmospheric background site in North China.The SO 2 concentrations of all three sites show a significant decrease from period before to after the control measures for the 2008 Olympic Games,suggesting that the SO 2 pollution control has long-term effectiveness and benefits.In the post-Olympics period,the mean concentrations of SO 2 at CMA,GCH,and SDZ are (14.3±11.0) ppb,(12.1±7.7) ppb,and (7.5±4.0) ppb,respectively,with reductions of 26%,36%,and 13%,respectively,compared to the levels before.Detailed analysis shows that the differences of temperature,relative humidity,wind speed,and wind direction were not the dominant factors for the significant differences of SO 2 between the pre-Olympics and post-Olympics periods.By extracting the data being more representative of local or regional characteristics,a reduction of up to 40% for SO 2 in polluted areas and a reduction of 20% for regional SO 2 are obtained for the effect of control measures implemented for the Olympic Games.Weili Lin Xiaobin XU Zhiqiang Ma Huarong Zhao Xiwen Liu Ying Wang 2012Journal of Environmental Sciences2012,24,1:15
8Metamodel-based Global Optimization Using Fuzzy Clustering for Design Space Reduction显示文摘High fidelity analysis are utilized in modern engineering design optimization problems which involve expensive black-box models.For computation-intensive engineering design problems,efficient global optimization methods must be developed to relieve the computational burden.A new metamodel-based global optimization method using fuzzy clustering for design space reduction(MGO-FCR) is presented.The uniformly distributed initial sample points are generated by Latin hypercube design to construct the radial basis function metamodel,whose accuracy is improved with increasing number of sample points gradually.Fuzzy c-mean method and Gath-Geva clustering method are applied to divide the design space into several small interesting cluster spaces for low and high dimensional problems respectively.Modeling efficiency and accuracy are directly related to the design space,so unconcerned spaces are eliminated by the proposed reduction principle and two pseudo reduction algorithms.The reduction principle is developed to determine whether the current design space should be reduced and which space is eliminated.The first pseudo reduction algorithm improves the speed of clustering,while the second pseudo reduction algorithm ensures the design space to be reduced.Through several numerical benchmark functions,comparative studies with adaptive response surface method,approximated unimodal region elimination method and mode-pursuing sampling are carried out.The optimization results reveal that this method captures the real global optimum for all the numerical benchmark functions.And the number of function evaluations show that the efficiency of this method is favorable especially for high dimensional problems.Based on this global design optimization method,a design optimization of a lifting surface in high speed flow is carried out and this method saves about 10 h compared with genetic algorithms.This method possesses favorable performance on efficiency,robustness and capability of global convergence and gives a new optimization strategy for engineering design optimization problems involving expensive black box models.LI Yulin LIU Li LONG Teng DONG Weili 2013Chinese Journal of Mechanical Engineering2013,26,5:13
9CRISPR/Cas9-mediated PINK1 deletion leads to neurodegeneration in rhesus monkeys显示文摘Dear Editor,PINK1 mutations cause autosomal recessive and early-onset Parkinson’s disease(PD)with selective neurodegeneration.Unfortunately,current PINK1 knockout(KO)mouse1,2 and pig models3,4 are unable to recapitulate the selective and overt neurodegeneration seen in PD patients.Furthermore,endogenous Pink1 in the mouse brain is expressed at very low levels and can only be detected via immunoprecipitation,5 meaning that PINK1’s function in the mammalian brain needs to be assessed using larger animals that are closer to humans.We previously used CRISPR/Cas9 to target the monkey gene in one-cell stage embryos.6 Using the same approach,we designed two gRNAs to target exon 2(T1)and exon 4(T2),which encode a kinase domain in the PINK1 gene of rhesus monkeys(Fig.1a).CRISPR/Cas9 and PINK1 gRNAs were injected into one-cell stage rhesus monkey embryos.A T7E1 assay and sequencing of PCR products from the injected embryos showed high efficiency(61.5%)in targeting PINK1(Fig.1b and Supplementary information,Fig.S1).Transfer of 87 embryos to 28 surrogate rhesus monkeys resulted in 11 pregnancies(39.2%)(Fig.1b).Eleven fetuses developed to term and were born naturally.Of these live monkeys,eight carried PINK1 mutations(M),and three were wild type(WT).However,three mutant monkeys(M1,M3 and M4)were newborn triplets that struggled to survive and died 3-4 days after birth.One WT newborn monkey also died after a difficult labor.Another mutant monkey(M2)died 7 days after birth without noticeable warning signs or symptoms.The other three mutant monkeys(M6,M7 and M8)have lived for three years;M5,however,reduced its food intake and showed weakness at the age of 1.5 years,and died 30 days after anesthesia for MRI examination.Weili Yang Yunbo Liu Zhuchi Tu Chong Xiao Sen Yan Xishan Ma Xiangyu Guo Xiusheng Chen Peng Yin Zhengyi Yang Su Yang Tianzi Jiang Shihua Li Chuan Qin Xiao-Jiang Li 2019Cell Research2019,29,4:12
10Outcomes in refractory diffuse large B-cell lymphoma:results fromamulticenter real-world study in China显示文摘Background:Diffuse large B-cell lymphoma(DLBCL)patients refractory to rituximab-based immunochemotherapy have a dismal prognosis.However,the definition of refractory DLBCL remains inconsistent and no large cohort study data is available from Asian countries.To validate the definition and outcomes of refractory DLBCL in China,we conducted a multicenter,retrospective cohort study.Methods:The REtrospective AnaLysis of Treatment REspoNse of refractory DLBCL(REAL-TREND)study was performed using real-world data from 8 centers in China.DLBCL patients with curative intent were included in the REAL-TREND dataset.Overall survival(OS)was estimated using the Kaplan-Meier method and compared by the log-rank test.Due to heterogeneity in response rates among different centers,the response rates of refractory patients were pooled using random-effect models.Multivariate survival analysis was performed using the Cox regression model.Results:A total of 2778 DLBCL patients diagnosed between January,2010 and December,2015 were enrolled to this study.After validating previous definitions,the SCHOLAR-1 study was most suitable to define refractory DLBCL.The estimated 5-year cumulative incidence of refractory patients was 20%(95% confidence Interval[CI]=18%-22%).After the determination of refractory disease,overall response rate and complete remission rate were 30%(95%CI=22%-38%)and 9%(95%CI=4%-15%),respectively.Patients with either no response to immunochemotherapy or relapse within 12 months after stem-cell transplantation had inferior survival with a median OS of 5.9 months(95%CI=5.5-7.1 months)and 2-year OS rate of 16%(95%CI=12%-20%).International prognostic index score 4-5(hazard ratio[HR]=2.22;95%CI=1.47-3.35),central nervous systemrelapse(HR=1.43;95%CI=1.04-1.97),and best response status(HR=2.68;95%CI=1.42-5.03 for partial remission.HR=5.97,95%CI=3.21-11.11 for stable disease/progressive disease)were independent unfavorable prognostic factors.Conclusions:This is the first large-scale Asian cohort study focusing on outcomes of refractory DLBCL.The definition of the SCHOLAR-1 study identifies patients with homogenously inferior survival,thus is appropriate to select refractory DLBCL.Due to poor clinical outcomes in the rituximab era,patients with refractory DLBCL may be potential candidates for novel treatment modalities.Shuo Wang Li Wang Jianda Hu Wenbin Qian Xi Zhang Yu Hu Qi Zhu Bobin Chen Depei Wu Chung-Chou H.Chang Pengpeng Xu Xiaoyun Zheng Juying Wei Yao Liu Guohui Cui Yong Tang Yan Ma Haiwen Huang Hongmei Yi Weili Zhao 2021Cancer Communications2021,41,3:10
11Generation of ready to use (RTU) products over China based on Landsat series data显示文摘Earth observation community has entered into the era of big data.Family of Landsat sensors have collected massive medium resolution satellite images,which are valuable for long-term land surface monitoring.In order to significantly reduce the magnitude of data processing for remote sensing data users,Landsat-based Ready to Use(RTU)products have been produced.Main RTU products,including orthorectified products,land surface reflectance,land surface temperature,large-area mosaic image,and standard image map products,are described.The resulting Landsat RTU products are hosted on the RSGS earth observation data sharing web site for free download(http://gffzz959b1a8e74bf485dhp9ubv0xqqp0o60uk.ffgz.tsg.suse.edu.cn/rtu/).These new products will provide consistent,standardized,multi-decadal image data for robust land cover change detection and monitoring across the Earth sciences.In the coming years,CASEarth DataBank system will be constructed,which is an intelligent data service platform for providing not only the RTU products from multi-source satellite data,but also big earth data analysis methods.Guojin He Zhaoming Zhang Weili Jiao Tengfei Long Yan Peng Guizhou Wang Ranyu Yin Wei Wang Xiaomei Zhang Huichan Liu Bo Cheng Bo Xiang 2018Big Earth Data2018,2,1:8

13Degradation of 4-nitrophenol by electrocatalysis and advanced oxidation processes using Co3O4@C anode coupled with simultaneous CO2 reduction via SnO2/CC cathode显示文摘Herein,we prepa red novel three-dimensional(3D)gear-s haped Co3O4@C(Co3O4 modified by amorphous carbon)and sheet-like SnO2/CC(SnO2 grow on the carbon cloth)as anode and cathode to achieve efficient removal of 4-nitrophenol(4-NP)in the presence of peroxymonosulfate(PMS)and simultaneous electrocatalytic reduction of CO2,respectively.In this process,4-NP was mineralized into CO2 by the Co3O4@C,and the generated CO2 was reduced into HCOOH by the sheet-like SnO2/CC cathode.Compared with the pure Co0.5(Co3O4 was prepared using 0.5 g urea)with PMS(30 mg,0.5 g/L),the degradation efficiency of 4-NP(60 mL,10 mg/L)increased from 74.5%-85.1%in 60 min using the Co0.5 modified by amorphous carbon(Co0.5@C).Furthermore,when the voltage of 1.0 V was added in the anodic system of Co0.5@C with PMS(30 mg,0.5 g/L),the degradation efficiency of 4-NP increased from 85.1%-99.1%when Pt was used as cathode.In the experiments of 4-NP degradation coupled with simultaneous electrocatalytic CO2 reduction,the degradation efficiency of 4-NP was 99.0%in the anodic system of Co0.5@C with addition of PMS(30 mg,0.5 g/L),while the Faraday efficiency(FE)of HCOOH was 24.1%at voltage of-1.3 V using the SnO2/CC as cathode.The results showed that the anode of Co3O4 modified by amorphous carbon can markedly improve the degradation efficiency of 4-NP,while the cathode of SnO2/CC can greatly improve the FE and selectivity of CO2 reduction to HCOOH and the stability of cathode.Finally,the promotion mechanism was proposed to explain the degradation of organic pollutants and reduction of CO2 into HCOOH in the process of electrocatalysis coupled with advanced oxidation processes(AOPs)and simultaneous CO2 reduction.Meng Zhu Longshuai Zhang Shanshan Liu Dengke Wang Yuancheng Qin Ying Chen Weili Dai Yuehua Wang Qiuju Xing Jianping Zou 2020Chinese Chemical Letters2020,31,7:7
14Dynamic analysis of granite rockburst based on the PIV technique显示文摘This paper describes the deep rockburst simulation system to reproduce the granite instantaneous rockburst process.Based on the PIV(Particle Image Velocimetry)technique,quantitative analysis of a rockburst,the images of tracer particle,displacement and strain fields can be obtained,and the debris trajectory described.According to the observation of on-site tests,the dynamic rockburst is actually a gas–solid high speed flow process,which is caused by the interaction of rock fragments and surrounding air.With the help of analysis on high speed video and PIV images,the granite rockburst failure process is composed of six stages of platey fragment spalling and debris ejection.Meanwhile,the elastic energy for these six stages has been calculated to study the energy variation.The results indicate that the rockburst process can be summarized as:an initiating stage,intensive developing stage and gradual decay stage.This research will be helpful for our further understanding of the rockburst mechanism.Wang Hongjian Liu Da'an Gong Weili Li Liyun 2015International Journal of Mining Science and Technology2015,25,2:6

19Mechanically reprogrammable Pancharatnam-Berry metasurface for microwaves显示文摘Metasurfaces have enabled the realization of several optical functionalities over an ultrathin platform,fostering the exciting field of flat optics.Traditional metasurfaces are achieved by arranging a layout of static meta-atoms to imprint a desired operation on the impinging wavefront,but their functionality cannot be altered.Reconfigurability and programmability of metasurfaces are the next important step to broaden their impact,adding customized on-demand functionality in which each meta-atom can be individually reprogrammed.We demonstrate a mechanical metasurface platform with controllable rotation at the meta-atom level,which can implement continuous Pancharatnam–Berry phase control of circularly polarized microwaves.As the proof-of-concept experiments,we demonstrate metalensing,focused vortex beam generation,and holographic imaging in the same metasurface template,exhibiting versatility and superior performance.Such dynamic control of electromagnetic waves using a single,low-cost metasurface paves an avenue towards practical applications,driving the field of reprogrammable intelligent metasurfaces for a variety of applications.Quan Xu Xiaoqiang Su Xueqian Zhang Lijuan Dong Lifeng Liu Yunlong Shi Qiu Wang Ming Kang Andrea Alù Shuang Zhang Jiaguang Han Weili Zhang 2022Advanced Photonics2022,4,1:5
20Shikimic Acid Promotes Oligodendrocyte Precursor Cell Differentiation and Accelerates Remyelination in Mice显示文摘The obstacle to successful remyelination in demyelinating diseases, such as multiple sclerosis, mainly lies in the inability of oligodendrocyte precursor cells(OPCs) to differentiate, since OPCs and oligodendrocytelineage cells that are unable to fully differentiate are found in the areas of demyelination. Thus, promoting the differentiation of OPCs is vital for the treatment of demyelinating diseases. Shikimic acid(SA) is mainly derived from star anise, and is reported to have antiinfluenza, anti-oxidation, and anti-tumor effects. In the present study, we found that SA significantly promoted the differentiation of cultured rat OPCs without affecting their proliferation and apoptosis. In mice, SA exerted therapeutic effects on experimental autoimmune encephalomyelitis(EAE), such as alleviating clinical EAE scores, inhibiting inflammation, and reducing demyelination in the CNS. SA also promoted the differentiation of OPCs as well as their remyelination after lysolecithin-induced demyelination.Furthermore, we showed that the promotion effect of SA on OPC differentiation was associated with the up-regulation of phosphorylated m TOR. Taken together, our resultsdemonstrated that SA could act as a potential drug candidate for the treatment of demyelinating diseases.Fengfeng Lu Dou Yin Yingyan Pu Weili Liu Zhenghao Li Qi Shao Cheng He Li Cao 2019Neuroscience Bulletin2019,35,3:4
