2Flower-, wire-, and sheet-like MnO_2-deposited diatomites:Highly efficient absorbents for the removal of Cr(Ⅵ)显示文摘Flower-, wire-, and sheet-like MnO2-deposited diatomites have been prepared using a hydrothermal method with Mn(Ac)2, KMnO4and/or MnSO4 as Mn source and diatomite as support. Physical properties of the materials were characterized by means of numerous analytical techniques, and their behaviors in the adsorption of chromium(VI) were evaluated.It is shown that the MnO2-deposited diatomite samples with different morphologies possessed high surface areas and abundant surface hydroxyl groups(especially the wire-like MnO2/diatomite sample). The wire-like MnO2/diatomite sample showed the best performance in the removal of Cr(VI), giving the maximum Cr(VI) adsorption capacity of 101 mg/g.Yucheng Du Liping Wang Jinshu Wang Guangwei Zheng Junshu Wu Hongxing Dai 2015Journal of Environmental Sciences2015,27,3:17

4Algorithm for Smooth S-curve Feedrate Profiling Generation显示文摘The algorithms for feedrate profile generation,such as linear and S-curve profiles,have been widely used in machinery controllers,and these algorithms can greatly improve the smoothness of motion.However,most of the algorithms lead to the discontinuous acceleration/deceleration and jerk,or high jerk levels,which is very harmful to machine tool or robot in most occasions. This paper presents a smooth S-curve feedrate profiling generation algorithm that produces continuous feedrate,acceleration,and jerk profiles.Smooth jerk is obtained by imposing limits on the first and second time derivatives of acceleration,resulting in trapezoidal jerk profiles along the tool path.The discretization of smooth S-curve feedrate is realized with a novel approach that improves the efficiency without calculating the deceleration point in each sampled time.To ensure that the interpolation time is a multiple of the value of sampled time,the feedrate,acceleration,jerk,and jerk derivative are recalculated.Meantime,to improve the efficiency,the interpolation steps of all regions are computed before interpolation.According to the distance of trajectory,the smooth S-curve acceleration and decelerations are divided into three blocks:normal block,short block type-Ⅰ,and short block type-Ⅱ.Finally feedrate discretization of short block type-Ⅰand type-Ⅱis obtained with considering the efficiency.The proposed generation algorithm is tested in machining a part on a five axis milling machine,which is controlled with the CNC system for newly developed high-speed machine tools.The test result shows that the smooth S-curve approach has the smoother feedrate,acceleration,deceleration,and jerk profiles than S-curve.The proposed algorithm ensures the automated machinery motion smoothness,and improves the quality and efficiency of the automated machinery motion planning.CHEN Youdong WEI Hongxing SUN Kai LIU Miao WANG Tianmiao 2011Chinese Journal of Mechanical Engineering2011,24,2:13
5GSA:Genome Sequence Archive显示文摘With the rapid development of sequencing technologies towards higher throughput and lower cost, sequence data are generated at an unprecedentedly explosive rate. To provide an efficient and easy-to-use platform for managing huge sequence data, here we present Genome Sequence Archive(GSA; http://gffzzdbc7b6aaae734bddho6wk5wvqqv6566xu.ffgz.tsg.suse.edu.cn/gsa or http://gffzz4eaf941a184140e3ho6wk5wvqqv6566xu.ffgz.tsg.suse.edu.cn), a data repository for archiving raw sequence data.

6Toward an improved data stewardship and service for environmental and ecological science data in West China显示文摘Sharing of scientific data can help scientific research to flourish and facilitate more widespread use of scientific data for the benefit of society.The Environmental and Ecological Science Data Center for West China(WestDC),sponsored by the National Natural Science Foundation of China(NSFC),aims to collect,manage,integrate,and disseminate environmental and ecological data from western China.It also aims to provide a long-term data service for multidisciplinary research within NSFC’s‘‘Environment and Ecology of West China Research Plan’’(NSFC West Plan).An integrated platform has been developed by the WestDC,and this has the function of data sharing,acting as a knowledge repository.Major data sets developed by the WestDC include basic geographic data,the regionalization of global data set for China,scientific data for cold and arid regions in China,scientific data for the cryosphere in countries that neighbor China,data relating to the inland river basins in northwestern China,and data submitted by the NSFC West Plan projects.In compliance with the‘‘full and open’’data sharing policy,most data in the WestDC can be accessed online.Highlights include detailed data documentation,the integration of data with bibliographic knowledge,data publishing,and data reference.Xin Li Zhuotong Nan Guodong Cheng Yongjian Ding Lizong Wu Liangxu Wang Jian Wang Youhua Ran Hongxing Li Xiaoduo Pan Zhongming Zhu 2011International Journal of Digital Earth2011,4,4:11
7Fissure evolution and evaluation of pressure-relief gas drainage in the exploitation of super-remote protected seams显示文摘Based on nonlinearity contact theory and the geological structure of the Xieqiao Coal Mine in the newly developed Huainan coal field,rock movements,mining fissures and deformation of overlying strata were simulated by using the interface unit of FLAC3D to evaluate the pressure-relief gas drainage in the exploitation of super-remote protected seams.The simulation indicates that the height of the water flowing fractured zone is 54 m in the overlying strata above the protective layer.The maximum relative swelling deformation of the C13 coal seam is 0.232%,while the mining height is 3.0 m and the distance from the B8 roof to the C13 floor is 129 m,which provides good agreement with a similar experiment and in situ results.The feasibility of exploitation of a super-remote protective coal seam and the performance of the pressure-relief gas drainage in a super-remote protected layer are evaluated by comparisons with practice projects.It demonstrates that the relieved gas in the super-remote protected layers could be better drained and it is feasible to exploit the B8 coal seam before the C13 super-remote protected coal seam.The method is applicable for the study of rock movements,mining fissures and deformation of the overburden,using the interface unit to analyze the contact problems in coal mines.LIU, Hongyong CHENG, Yuanping ZHOU, Hongxing WANG, Feng CHEN, Haidong 2010Mining Science and Technology2010,20,2:10
8Development of Hydro-Informatic Modelling System and its application显示文摘The understanding of hydrological cycle is the core of hydrology and the scientific base of water resources management. Meanwhile, simulation of hydrological cycle has long been regarded as an important tool for the assessment, utilization and protection of water resources. In this paper, a new tool named Hydro-Informatic Modelling System (HIMS) has been developed and introduced with case studies in the Yellow River Basin in China and 331 catchments in Australia. The case studies showed that HIMS can be employed as an integrated platform for hydrological simulation in different regions. HIMS is a modular based framework of hydrological model designed for different utilization such as flood forecasting, water resources planning and evaluating hydrological impacts of climate change and human activities. The unique of HIMS is its flexibility in providing alternative modules in the simulation of hydrological cycle, which successfully overcome the difficulties in the availability of input data, the uncertainty of parameters, and the difference of rainfall-runoff processes. The modular based structure of HIMS makes it possible for developing new hydrological models by the users.LIU ChangMing WANG ZhongGen ZHENG HongXing ZHANG Lu WU XianFeng 2008Science China(Technological Sciences)2008,51,4:9
9Maximal capacity nonorthogonal pulse shape modulation显示文摘To improve spectral utilization of communication system, a novel nonorthogonal pulse shape modulation(NPSM) based on prolate spheroidal wave function(PSWF) is proposed. The modulation employs nonorthogonal PSWF pulses to transmit information and it shows a higher capacity than traditional orthogonal modulations. The NPSM capacity under the constraint of finite input alphabet, which is determined by parameters of PSWF pulse, is derived. An optimization model for maximal capacity of NPSM is constructed and an exhaustive self-adapting gradient search algorithm for the model is proposed. A practical NPSM scheme with the maximal capacity is obtained by this search algorithm and it is proved to be superior to orthogonal signaling in the capacity. Our theoretical analysis is validated by numerical simulations and practical tests, and the results show that NPSM outperforms orthogonal modulations in the capacity and has a lower Peak-to-Average Power Ratio.Chen Zhaonan Wang Hongxing Liu Xiguo Zhong Peilin 2015Chinese Journal of Aeronautics2015,28,6:8
10Task-related functional magnetic resonance imaging-based neuronavigation for the treatment of depression by individualized repetitive transcranial magnetic stimulation of the visual cortex显示文摘To determine whether repetitive transcranial magnetic stimulation(rTMS)of the visual cortex(VC)provides effective and welltolerated treatment and whether magnetic resonance imaging(MRI)measures functional change of the VC as a biomarker of therapeutic effect in major depressive disorder(MDD),we performed a sham-controlled,double-blind,randomized,three-arm VC rTMS treatment study in 74 MDD patients.Neuronavigated rTMS(10 Hz,90%of resting motor threshold,1,600 pulses over20 min twice per day)was performed over the VC for five days.Clinical outcome was measured by Hamilton Depression Rating Scale(HAMD-24)at days 0,1,3,5 and after terminating rTMS,with follow-up at four weeks.MRI was measured at days 0 and5.The individualized group exhibited the greatest change in HAMD-24 scores after VC rTMS for 5 days(F=5.53,P=0.005),which were maintained during follow-up period(F=4.22,P=0.016).All patients reported good tolerance.Changes in VC taskrelated functional MRI correlated with symptomatic reduction in the individualized group.Treatment reduced the initially abnormal increase in resting state functional connectivity from the VC to the pre/subgenual anterior cingulate cortex at day 5,especially in the individualized group.We demonstrated therapeutic potential and good tolerance of VC rTMS in MDD patients,indicated by biomarkers of f MRI measurement.Zhijun Zhang Hongxing Zhang Chun-Ming Xie Meng Zhang Yachen Shi Ruize Song Xiang Lu Haisan Zhang Kun Li Bi Wang Yongfeng Yang Xianrui Li Jianli Zhu Yang Zhao Ti-Fei Yuan Georg Northoff 2021Science China(Life Sciences)2021,64,1:8
11MicroRNA-324-3p Plays A Protective Role Against Coxsackievirus B3-Induced Viral Myocarditis显示文摘Viral myocarditis(VM) is an inflammatory disease of the myocardium associated with heart failure, which is caused by common viral infections. A majority of the infections are initiated by coxsackievirus B3(CVB3). Micro RNAs(mi RNAs)have a major role in various biological processes, including gene expression, cell growth, proliferation, and apoptosis, as well as viral infection and antiviral immune responses. Although, mi RNAs have been found to regulate viral infections,their role in CVB3 infection remains poorly understood. In the previous study, mi RNA microarray results showed that mi R-324-3 p expression levels were significantly increased when cells and mice were infected with CVB3. It was also found that miR-324-3p downregulated TRIM27 and decreased CVB3 replication in vitro and in vivo. In vitro, analysis of downstream signaling of TRIM27 revealed that, miR-324-3p inhibited CVB3 infection, and reduced cytopathic effect and viral plaque formation by reducing the expression of TRIM27. In vivo, miR-324-3p decreased the expression of TRIM27,reduced cardiac viral replication and load, thereby strongly attenuating cardiac injury and inflammation. Taken together,this study suggests that miR-324-3p targets TRIM27 to inhibit CVB3 replication and viral load, thereby reducing the cardiac injury associated with VM.Tingjun Liu Jing Tong Chen Shao Junyan Qu Hua Wang Yi Shi Yajing Lin Yun Liu Shihe Shao Hongxing Shen 2021Virologica Sinica2021,36,6:8
12Graphene-enabled electrically controlled terahertz meta-lens显示文摘Metasurfaces have become a new photonic structure for providing potential applications to develop integrated devices with small thickness, because they can introduce an abrupt phase change by arrays of scatterers. To be applied more widely, active metasurface devices are highly desired. Here, a tunable terahertz meta-lens whose focal length is able to be electrically tuned by ~4.45λ is demonstrated experimentally. The lens consists of a metallic metasurface and a monolayer graphene. Due to the dependence of the abrupt phase change of the metasurface on the graphene chemical potential, which can be modulated using an applied gate voltage, the focal length is changed from 10.46 to 12.24 mm when the gate voltage increases from 0 to 2.0 V. Experimental results are in good agreement with the theoretical hypothesis. This type of electrically controlled meta-lens could widen the application of terahertz technology.WEIGUANG LIU BIN HU ZONGDUO HUANG HONGYU GUAN HETING LI XINKE WANG YAN ZHANG HONGXING YIN XIAOLU XIONG JUAN LIU YONGTIAN WANG 2018Photonics Research2018,6,7:8
13Soil temperature and moisture sensitivities of soil CO_2 efflux before and after tillage in a wheat field of Loess Plateau,China显示文摘As a conventional farming practice,tillage has lasted for thousands of years in Loess Plateau,China.Although recent studies show that tillage is a prominent culprit to soil carbon loss in croplands,few studies have investigated the influences of tillage on the responses of soil CO2 efflux(SCE) to soil temperature and moisture.Using a multi-channel automated CO2 efflux chamber system,we measured SCE in situ continuously before and after the conventional tillage in a rain fed wheat field of Loess Plateau,China.The changes in soil temperature and moisture sensitivities of SCE,denoted by the Q10 value and linear regression slope respectively,were compared in the same range of soil temperature and moisture before and after the tillage.The results showed that,after the tillage,SCE increased by 1.2-2.2 times;the soil temperature sensitivity increased by 36.1%-37.5%;and the soil moisture sensitivity increased by 140%-166%.Thus,the tillage-induced increase in SCE might partially be attributed to the increases in temperature and moisture sensitivity of SCE.Hongxing Zhang Xiaoke Wang Zongwei Feng Junzhu Pang Fei Lu Zhiyun Ouyang Hua Zheng Wenzhao Liu Dafeng Hui 2011Journal of Environmental Sciences2011,23,1:7
14Evaluation of three tracers for labeling distal cerebrospinal fluidcontacting neurons显示文摘It has been reported that distal cerebrospinal fluidcontacting neurons(dCSF-CNs)can be detected by immunohistochemical assay using cholera toxin subunit B-conjugated horseradish peroxidase(CBHRP).In the present study,another two methods with CB alone or CB-conjugated FITC(CB-FITC)were used,and the results from the three methods were compared.Adult Sprague-Dawley rats were randomly divided into three groups with CB-HRP,CB or CB-FITC.Tracers were diluted to 30%in artificial cerebrospinal fluid and injected separately(in a volume of 3μL)into the lateral ventricle.Animals from the CB-HRP and CB groups were perfused 48 h after surgery while animals from the CB-FITC group were perfused 1,3,6,12,24 or 48 h after surgery.The brain was sectioned(40μm)for immunofluorescence and five sections with positive neurons were selected from each rat for neuron counting.Three clusters of positive neurons in a'Y-like'distribution were detected ventral to the cerebral aqueduct of rats from the three groups.No significant difference was observed among the quantitative data.In the CB-FITC group,stable staining was detected even at 6 h after injection.Taken together,lateral ventricle injection of CB/CB-FITC is a useful method for labeling dCSFCNs in rats.The CB-FITC method makes dCSF-CNs labeling much simpler and more convenient.Fang Zhou Jiayou Wang Hongxing Zhang He Liu Guangping Zhao Cuihua Zu Xiaoxing Lu Licai Zhang 2013Neuroscience Bulletin2013,29,5:7
15Remotely excited Raman optical activity using chiral plasmon propagation in Ag nanowires显示文摘We experimentally investigated remotely excited Raman optical activity(ROA)using propagating surface plasmons in chiral Ag nanowires.Using chiral fmoc-glycyl-glycine-OH(FGGO)molecules,we first studied the local surface plasmon-enhanced ROA.We found that the Raman intensity can be excited by left-and right-circularly polarized lights and that the circular intensity difference(CID)can be significantly enhanced.Second,by selecting vibrational modes with large Raman and ROA intensities that are not influenced by chemical enhancements,we studied remotely excited ROA imaging and the CID of FGGO molecules by propagating a plasmonic waveguide using Ag chiral nanostructures.When laser light was radiated on one of the Ag terminals,the measured CID of the FGG at the other terminal showed little change compared to the local excited CID.Meanwhile,when the laser light was radiated on the Ag nanowires(not on the terminals)and was coupled to the nearby nanoantenna,the CID of the ROA could be manipulated by altering the coupling angle between the Ag nanowires.To directly demonstrate the propagation of ROA along the nanowire and its remote detection,we also measured the remotely excited ROA spectra.Our experimental method has the potential to remotely determine the chirality of molecular structures and the absolute configuration or conformation of a chiral live cell.Mengtao Sun Zhenglong Zhang Peijie Wang Qiang Li Fengcai Ma Hongxing Xu 2013Light(Science & Applications)2013,2,1:7

17Marginal linearization method in modeling on fuzzy control systems显示文摘Marginal linearization method in modeling on fuzzy control systems is proposed, which is to deal with the nonlinear model with variable coefficients. The method can turn a nonlinear model with variable coefficients into a linear model with variable coefficients in the way that the membership functions of the fuzzy sets in fuzzy partitions of the universes are changed from triangle waves into rectangle waves. However, the linearization models are incomplete in their forms because of their lacking some items. For solving this problem, joint approximation by using linear models is introduced. The simulation results show that marginal linearization models are of higher approximation precision than their original nonlinear models.LI Hongxing , WANG Jiayin and MIAO Zhihong(Department of Mathematics, Beijing Normal University, Beijing 100875, China) 2003Progress in Natural Science:Materials International2003,13,7:6
18Investigating changes in lake systems in the south-central Tibetan Plateau with multi-source remote sensing显示文摘在西藏的高原的湖被认为应答者敏感到全球温暖。在象表面区域和水水平那样的湖系统的物理特征的变化在理解地区性的回答到在最近的十年的全球温暖是很有用的。在这研究,多来源遥感数据被用来在过去的十年在西藏的高原的南方中央的部分检索表面区域和五个内陆湖的水水平时间系列。在水水平和湖的表面区域的变化被调查。结果证明水三铺平湖(美洲狮 Yumco,芋头公司, Zhari Namco ) 增加与扩展表面区域,当水另外的二个湖铺平时(Paiku 公司, Mapam Yumco ) 掉落,与缩小区域。湖的水层次作为与 1976-1999 相比在 2000-2012 经历了显著变化。空间地,在西藏的高原的南部的穗定位的湖在水水平变化显示出一致性,它与在中央西藏的高原的湖不同。WU Yanhong ZHANG Xin ZHENG Hongxing LI Junsheng WANG Zhiying 2017Journal of Geographical Sciences2017,27,3:5
19Analysis of the Impact of the Space Guide Vane Wrap Angle on the Performance of a Submersible Well Pump显示文摘In order to study the influence of the wrap angle relating to the space guide vane of a submersible well pump(250QJ125)on the flow field and pump performance,seven possible configurations have been considered(obtained by changing the blade wrap angle while keeping unchanged all the other parameters).Such configurations have been numerically simulated in the framework of a computational model based on the Reynolds time-averaged N-S equations,the RNG k-εturbulence approach and the SIMPLE algorithm.The impact exerted by different wrap angles of the guide vane on the performance of the pump,the internal losses of the guide vane and the flow field distribution in the bladeless area at the guide vane outlet has been assessed via cross-comparison of all these cases.The results show that the wrap angle has a significant influence:the wrap angle with the highest head is different from that with the highest efficiency,and changes in this angle have a more significant effect on the head than efficiency.A moderate raise of the wrap angle can improve the properties of the flow,reduce turbulence losses and enhance the energy conversion rate inside the guide vane.Different wrap angles can also lead to different fluid circulation modes in the bladeless area from guide vane outlet to impeller inlet,while they have a weak influence on the absolute value of the velocity of the fluid entering the impeller.Xiaorui Cheng Hongxing Chen Xiaoquan Wang 2019Fluid Dynamics & Materials Processing2019,15,3:5
20CsPbBr_3 perovskite quantum dots: saturable absorption properties and passively Q-switched visible lasers显示文摘This work presents the saturable absorption(SA) properties of CsPbBr_3 perovskite quantum dots(QDs). The perovskite QDs show excellent SA performance with a nonlinear absorption coefficient of-35 × 10^(-2) cm∕GW and a figure of merit of 3.7 × 10^(-14) esu cm. Further, their use as saturable absorbers in a passively Q-switched visible solid-state laser for the generation of soliton pulses is demonstrated. These results demonstrate thepotential for the perovskite QDs to act as saturable absorbers.JINGZHOU LI HONGXING DONG BIN XU SAIFENG ZHANG ZHIPING CAI JUN WANG LONG ZHANG 2017Photonics Research2017,5,5:5
