| 1 | Geospatial Service Web:towards integrated cyberinfrastructure for GIScience显示文摘A geospatial cyberinfrastructure is needed to support advanced GIScience research and education activities.However,the heterogeneous and distributed nature of geospatial resources creates enormous obstacles for building a unified and interoperable geospatial cyberinfrastructure.In this paper,we propose the Geospatial Service Web(GSW)to underpin the development of a future geospatial cyberinfrastructure.The GSW excels over the traditional spatial data infrastructure by providing a highly intelligent geospatial middleware to integrate various geospatial resources through the Internet based on interoperable Web service technologies.The development of the GSW focuses on the establishment of a platform where data,information,and knowledge can be shared and exchanged in an interoperable manner.Theoretically,we describe the conceptual framework and research challenges for GSW,and then introduce our recent research toward building a GSW.A research agenda for building a GSW is also presented in the paper. | GONG Jianya WU Huayi ZHANG Tong GUI Zhipeng LI Zhenlong YOU Lan SHEN Shengyu ZHENG Jie GENG Jing QI Kunlun YANG Wenjing LI Zhenqiang YU Jingmin | 2012 | Geo-Spatial Information Science2012，15，2： | 5 |
| 2 | Regulating electrolytic Fe_(0.5)CoNiCuZn_(x) high entropy alloy electrodes for oxygen evolution reactions in alkaline solution显示文摘The properties of high entropy alloys(HEAs)depend on their phase structures and compositions.However,it is difficult to control the composition of the HEAs that contain highly volatile metals by the conventional arc melting method.In this paper,homogeneous powdery face centered cubic(FCC)phase Fe_(0.5)CoNiCuZn_(x) HEAs were prepared by the electrolysis of metal oxides in molten Na_(2)CO_(3)-K_(2)CO_(3) using a stable Ni11Fe10Cu inert oxygen-evolution anode.The use of oxide precursors and relatively low synthetic temperature are beneficial to efficiently preparing HEAs that contain highly volatile elements such as Zn.Moreover,the microstructures and compositions of the electrolytic HEAs can be easily tailored by adjusting the components of oxide precursors,then further regulating its properties.Thus,the electrocatalytic activity of Fe_(0.5)Co NiCuZn_(x) HEAs towards oxygen evolution reactions(OER)was investigated in 1 M KOH.The results show that Zn promotes the OER activity of Fe_(0.5)CoNiCuZn_(x) HEAs,i.e.,the HEA(Zn_(0.8))shows the best OER activity exhibiting a low overpotential of 340 m V at 10 m A/cm^(2) and excellent stability of 24 h.Hence,molten salt electrolysis not only provides a green approach to prepare Fe_(0.5)CoNiCuZn_(x) HEAs but also offers an effective way to regulate the structure of the alloys and thereby optimizes the electrocatalytic activities for water electrolysis. | Jian Huang Peilin Wang Peng Li Huayi Yin Dihua Wang | 2021 | Journal of Materials Science & Technology2021，，34： | 4 |
| 3 | Serum semaphorin 4C as a diagnostic biomarker in breast cancer:A multicenter retrospective study显示文摘Background:To date,there is no approved blood-based biomarker for breast cancer detection.Herein,we aimed to assess semaphorin 4C(SEMA4C),a pivotal protein involved in breast cancer progression,as a serum diagnostic biomarker.Methods:We included 6,213 consecutive inpatients from Tongji Hospital,Qilu Hospital,and Hubei Cancer Hospital.Training cohort and two validation cohorts were introduced for diagnostic exploration and validation.A pan-cancer cohort was used to independently explore the diagnostic potential of SEMA4C among solid tumors.Breast cancer patients who underwent mass excision prior to modified radical mastectomy were also analyzed.We hypothesized that increased pretreatment serum SEMA4C levels,measured using optimized in-house enzymelinked immunosorbent assay kits,could detect breast cancer.The endpoints were diagnostic performance,including area under the receiver operating characteristic curve(AUC),sensitivity,and specificity.Post-surgery pathological diagnosis was the reference standard and breast cancer staging followed the TNM classification.There was no restriction on disease stage for eligibilities.Results:We included 2667 inpatients with breast lesions,2378 patients with other solid tumors,and 1168 healthy participants.Specifically,118 patients with breast cancer were diagnosed with stage 0(5.71%),620 with stage I(30.00%),966 with stage II(46.73%),217 with stage III(10.50%),and 8 with stage IV(0.39%).Patients with breast cancer had significantly higher serum SEMA4C levels than benign breast tumor patients and normal controls(P<0.001).Elevated serum SEMA4C levels had AUC of 0.920(95%confidence interval[CI]:0.900–0.941)and 0.932(95%CI:0.911–0.953)for breast cancer detection in the two validation cohorts.The AUCs for detecting early-stage breast cancer(n=366)and ductal carcinoma in situ(n=85)were 0.931(95%CI:0.916–0.946)and 0.879(95%CI:0.832–0.925),respectively.Serum SEMA4C levels significantly decreased after surgery,and the reduction was more striking after modified radical mastectomy,compared with mass excision(P<0.001).The positive rate of enhanced serum SEMA4C levels was 84.77%for breast cancer and below 20.75%for the other 14 solid tumors.Conclusions:Serum SEMA4C demonstrated promising potential as a candidate biomarker for breast cancer diagnosis.However,validation in prospective settings and by other study groups is warranted. | Ya Wang Long Qiao Jie Yang Xiong Li Yaqi Duan Jiahao Liu Shaoqi Chen Huayi Li Dan Liu Tian Fang Jingjing Ma Xiaoting Li Fei Ye Junxiang Wan Juncheng Wei Qin Xu Ensong Guo Ping Jin Mingfu Wu Lin Zhang Yun Xia Yaqun Wu Jun Shao Yaojun Feng Qing Zhang Zongyuan Yang Gang Chen Qinghua Zhang Xingrui Li Shixuan Wang Junbo Hu Xiaoyun Wang Mona P.Tan Kazuaki Takabe Beihua Kong Qifeng Yang Ding Ma Qinglei Gao | 2021 | Cancer Communications2021，41，12： | 3 |
| 4 | A polypropylene melt-blown strategy for the facile and efficient membrane separation of oil-water mixtures显示文摘Porous materials with selective wettability and permeability have significant importance in oil-water separation,but complex fabrication processes are typically required to obtain the desired structures with suitable surface chemistry.In this work,an industrial melt-blown strategy that utilized commercially available polypropylene(PP)was used for the large-scale fabrication of superhydrophobic/superoleophilic membranes with staggered fabric structures.These membranes could readily separate different oils including pump oil and crude oil from various aqueous solutions such as strongly acidic,alkaline,and saline media.In addition,the separation efficiencies of these membranes exceeded 99%,and they could remain functional even after exposure to corrosive media.We anticipate that this work will further the design of membranes and enhance their applicability in oil-water separation,and provide researchers and engineers with a more effective tool for performing challenging separations and mitigating pollution. | Zhenqiang Zhang Danfeng Yu Xiubin Xu Huayi Li Taoyan Mao Cheng Zheng Jianjia Huang Hui Yang Zihan Niu Xu Wu | 2021 | Chinese Journal of Chemical Engineering2021，34，1： | 3 |
| 5 | Microfluidic-enabled ambient-temperature synthesis of ultrasmall bimetallic nanoparticles显示文摘The production of bimetallic nanoparticles with ultrasmall sizes is the constant pursuit in chemistry and materials science because of their promising applications in catalysis,electronics and sensing.Here we report ambient-temperature preparation of bimetallic NPs with tunable size and composition using microfluidic-controlled co-reduction of two metal precursors on silicon surface.Instead of free diffusion of metal ions in bulk system,microfluidic flow could well control the local ions concentration,thus leading to homogenous and controllable reduction rate among different nucleation sites.By controlling precursor concentration,flow rate and reaction time,we rationally design a series of bimetallic NPs including Ag-Cu,Ag-Pd,Cu-Pt,Cu-Pd and Pt-Pd NPs with ultrasmall sizes(~3.0 nm),tight size distributions(relative standard deviation(RSD)<21%),clean surface,and homogenous elemental compositions among particles(standard deviation(SD)of weight ratios<3.5%).This approach provides a facile,green and scalable method toward the synthesis of diverse bimetallic NPs with excellent activity. | Huayi Shi Bin Song Runzhi Chen Qiang Zhang Guyue Hu Jing Li Jinhua Wang Xinyu Meng Houyu Wang Yao He | 2022 | Nano Research2022，15，1： | 2 |
| 6 | Conversion of Carbonyl Compounds to Olefins via Enolate Intermediate显示文摘Summary of main observation and conclusion A general and efficient protocol to synthesize substituted olefins from carbonyl compounds via nickel catalyzed C-O activation of enolates was developed.Besides ketones,aldehydes were also suitable substrates for the presented catalytic system to produce di-or tri-substituted olefins.It is worth noting that this approach exhibited good tolerance to highly reactive tertiary alcohols,which could not survive in other reported routes for converting carbonyl compounds to olefins.This method also showed good regio-and stereo-selectivity for olefin products.Preliminary mechanistic studies indicated that the reaction was accomplished through nickel catalyzed C-O activation of enolates,thus offering helpful contribution to current enol chemistry. | Zhi-Chao Cao Pei-Lin Xu Qin-Yu Luo Xiao-Lei Li Da-Gang Yu Huayi Fang Zhang-Jie Shi | 2019 | Chinese Journal of Chemistry2019，37，8： | 2 |

| 8 | A stable oxygen evolution splitting electrocatalysts high entropy alloy FeCoNiMnMo in simulated seawater显示文摘Stabilizing anode for oxygen evolution(OER)in chlorine-containing electrolytes is a significant challenge.Adding corrosion inhibitors in electrolytes can alleviate this problem,but the type and dosage of cor-rosion inhibitors need a lot of exploration,and side reactions may occur to reduce current efficiency.Herein,we prepared a FeCoNiMnMo High entropy alloy(HEA)electrode for OER in simulated seawa-ter without corrosion inhibitors.It exhibits great electrocatalytic activity(overpotential(η)=237 mV at 10 mA cm^(-2))and excellent stability(200 h at 100 mA cm^(-2)).Experiments and Density Functional The-ory(DFT)calculation show that the protective layer containing K_(2)MoO_(4)is the crucial factor for chlorine resistance of FeCoNiMnMo electrode.The tightly adsorbed state of Cl-and K_(2)MoO_(4)ensures that other oxides are not corroded.And the externally added K_(2)MoO_(4)cannot protect the electrode.In addition,the high-entropy effect of HEA reduces the dissolution of the alloy.This work provides an efficient way to prepare a noble-free HEA catalyst that can stabilize oxygen evolution in corrosive electrolytes. | Peng Li Yuanpeng Yao Wengen Ouyang Ze Liu Huayi Yin Dihua Wang | 2023 | Journal of Materials Science & Technology2023，，7： | 2 |
| 9 | The influence of the metal net charge of non-metallocene early transition metal catalyst on the ethylene polymerization activity显示文摘The net charges on central metals of a serial non-metallocene early transition metal catalysts (FI catalyst) with similar steric hindrance were caculated with MM-QEq (molecular mechmism-charge equilibration) method and associated with ethylene polymerization activities of these FI catalyts. It was found that the activity increased with the net charge on metal if ignoring the influence of the steric hindrance. In other words, introduction of strong and/or more electron-withdrawing groups onto the ligand of FI catalyst would enhance the activity of the catalyst. This conculsion gave a direction to designing new FI catalyst with higher activity. | WU ChunHong LI HuaYi FENG YuQi HU YouLiang | 2008 | Chinese Science Bulletin2008，53，20： | 1 |
| 10 | Distributed cache replacement method for geospatial data using spatiotemporal localitybased sequence显示文摘Specific features of tile access patterns can be applied in a cache replacement strategy to a limited distributed high-speed cache for the cloud-based networked geographic information services(NGISs),aiming to adapt to changes in the access distribution of hotspots.By taking advantage of the spatiotemporal locality,the sequential features in tile access patterns,and the cache reading performance in the burst mode,this article proposes a tile sequence replacement method,which involves structuring a Least Recently Used(LRU)stack into three portions for the different functions in cache replacement and deriving an expression for the temporal locality and popularity of the relevant tile to facilitate the replacement process.Based on the spatial characteristics of both the tiles and the cache burst mode with regard to reading data,the proposed method generates multiple tile sequences to reflect spatiotemporal locality in tile access patterns.Then,we measure the caching value by a technique based on a weighted-based method.This technique draws on the recent access popularity and low caching costs of tile sequences,with the aim of balancing the temporal and spatial localities in tile access.It ranks tile sequences in a replacement queue to adapt to the changes in accessed hotspots while reducing the replacement frequency.Experimental results show that the proposed method effectively improves the hit rate and utilization rate for a limited distributed cache while achieving satisfactory response performance and high throughput for users in an NGIS.Therefore,it can be adapted to handle numerous data access requests in NGISs in a cloud-based environment. | Rui LI Jiapei FAN Xinxing WANG Zhen ZHOU Huayi WU | 2015 | Geo-Spatial Information Science2015，18，4： | 1 |

| 17 | Modeling and simulation of dynamic carbonate deposition in a loess-paleosol sequence显示文摘A compartment model of dynamic deposition processes has been developed and testedin the Potou loess section of China. There are four components in the model : carbonate input ofeolian dust, carbonate output of erosion, carbonate chemical equilibrium and soil water balance. Aclimate stochastic model software (CLIMAK) generates the daily weather data. The processes ofeolian dust deposition, erosion, and pedogenesis simulate the complex process of carbonatedeposition in a loess-paleosol sequence. We consider both climatic change and soil-forming factors.The results indicate that since the Late Pleistocene in Potou section, the mean carbonate fluxesfrom precipitation, eolian dust and erosion are 0.14g/cm^2/kg, 1.45g/cm^2/ka and 0.23g/cm^2/karespectively. Of this, 91.2% of the carbonate input is from eolian dust. | LI Xuyong LI Baoguo LU Huayi DUAN Jiannan SHI Yuanchun Commission for Integrated Survey of Natural Resources, CAS, Beijing 100101, China Department of Soil and Water, China Agricultural University, Beijing 100094.

| 20 | Conceptual rotational mode design for optical conical scanning imaging small satellites显示文摘This paper focuses upon the novel optical conical scanning imaging working mode design for small satellites.This kind of satellite employs only one inclined optical camera achieving wide-swath imaging via a rotational motion about the nadir axis either by the camera or by the satellite.Three working modes are designed,i.e.,high-speed rotational mode,low-speed rotational mode,and variable-speed rotational mode.For the high-speed and low-speed working modes,the camera rotates at a constant speed and the corresponding angular velocity is derived under the consideration of guaranteed coverage and minimized overlap.To improve the system performance,an enhanced working mode taking advantages of both the high-speed rotational mode and lowspeed rotational mode is proposed.Working in this variable-speed rotational mode,the camera rotates slowly to get high-quality pictures when it works,while it rotates rapidly to reduce the energy consumption and save the storage during which period the camera is turned off to minimize the overlap.All these working modes are illustrated in detail,and numerical simulation tests are conducted to validate their effectiveness. | WANG Feng XI RuiChen YUE ChengFei LI HuaYi CAO XiBin | 2020 | Science China(Technological Sciences)2020，63，8： | 1 |
