| 1 | Linkage between permafrost distribution and river runoff changes across the Arctic and the Tibetan Plateau显示文摘River runoff in the Arctic and the Tibetan Plateau(TP) change significantly in recent decades. However, the mechanisms of the physical processes of permafrost river runoff change remain uncertain across large scale. This study investigated the mainstreams and tributaries of main Arctic and TP rivers dominated by permafrost and assessed the linkage between hydrological regime change and permafrost. The results show that the effects of permafrost on river runoff are highly dependent on the permafrost coverage of a watershed. For the past decades, the majority of the Arctic and TP basins showed increased discharge, while all of the studied basins showed increased baseflow, with faster increasing speed than total discharge.Both total discharge and baseflow annual change rate(ΔQ and ΔBF) increased with permafrost coverage, indicating the increments of streamflow are enhanced with high permafrost coverage. Meanwhile, the annual change of precipitation showed weak connection with total discharge and baseflow change. The high permafrost coverage basins showed high annual maximum/minimum discharge ratio(Qmax/Qmin), while the Qmax/Qminchanged slightly in low permafrost cover basins. Our results highlight the importance of permafrost coverage on streamflow regime change for permafrost basins across the northern hemisphere. Due to these linkage between permafrost extent and runoff regime change and the increasing changes of permafrost, more attention should be paid to the change of hydrological processes in permafrost-underlain basins. | Chunlin SONG Genxu WANG Tianxu MAO Junchen DAI Daqing YANG | 2020 | Science China Earth Sciences2020，63，2： | 10 |

| 3 | Large-scale blow spinning of heat-resistant nanofibrous air filters显示文摘Particulate matter(PM)pollution has become a serious problem worldwide and various kinds of nanofibrous filters aiming to solve the problem have been developed.It is urgent to remove PM from high-temperature pollution sources,such as industrial emissions,coal furnaces,and automobile exhaust gases.However,filtration at pollution sources remains challenging because most existing air filters are not resistant to high temperature.Herein,heat-resistant polyimide(PI)nanofibrous air filters are fabricated via a simple and scalable solution blow-spinning method.These air filters show excellent thermal stability at high temperature up to 420℃.They exhibit a filtration efficiency as high as 99.73%at ambient temperature and over 97%at 300℃.In addition,a field test shows that the filters remove>97%of PM from the car exhaust fumes.Hence,the blow-spun PI nanofibrous membranes combined with the facile preparation strategy have great potential in high temperature air filtration fields and other similar applications such as water purification and protein separation. | Ziwei Li Jianan Song Yuanzheng Long Chao Jia Zhenglian Liu Lei Li Cheng Yang Junchen Liu Sen Lin Haiyang Wang Yibo Liu Minghao Fang Hui Wu | 2020 | Nano Research2020，13，3： | 6 |
| 4 | Low-Carbon and Nanosheathed ZnCo_(2)O_(4) Spheroids with Porous Architecture for Boosted Lithium Storage Properties显示文摘Multielectronic reaction electrode materials for high energy density lithium-ion batteries(LIBs)are severely hindered by their inherent sluggish kinetics and large volume variations,leading to rapid capacity fade.Here,a simple method is developed to construct low-carbon and nanosheathed ZnCo_(2)O_(4) porous spheroids(ZCO@C-5).In this micro/nanostructure,an ultrathin amorphous carbon layer(∼2 nm in thickness)is distributed all over the primary nanosized ZCO particles(∼20 nm in diameter),which fnally self-assembles into porous core(ZCO)-shell(carbon)micron spheroids.Te nanoencapsulation and macro/mesoporous architecture can not only provide facile electrolyte penetration and rapid ion/electron transfer but also better alleviate volumetric expansion efect to avoid pulverization of ZCO@C-5 spheroids during repeat charge/discharge processes.As expected,the three-dimensional porous ZCO@C-5 composites exhibit high reversible capacity of 1240 mAh g^(−1) cycle at 500 mA g^(−1),as well as excellent long-term cycling stability and rate capability.Te low-carbon and nanoencapsulation strategy in this study is simple and efective,exhibiting great potential for high-performance LIBs. | Yudi Mo Junchen Liu Shuanjin Wang Min Xiao Shan Ren Dongmei Han Yuezhong Meng | 2019 | Research2019，，1： | 3 |
| 5 | Drop casting based superhydrophobic and electrically conductive coating for high performance strain sensing显示文摘Conductive polymer composites(CPCs)strain sensors exhibit promising applications in flexible electronics,people’s health monitoring,etc.It remains a big challenge to develop a simple and cost-effective method to prepare CPCs with high conductivity,corrosion resistance,strong interfacial adhesion and high sensitivity.Here,we propose a facile“drop-casting and fluorination”strategy to fabricate superhydrophobic and highly electrically conductive coating by Ag precursor adsorption onto a commercially available elastic tape,subsequent chemical reduction and final fluorination.The Ag nanoparticles could not only construct the electrically conductive network but also greatly enhance the surface roughness.The contact angle and electrical conductivity of the coating can reach as high as 156°and 126 S/cm,respectively.When used for strain sensing,the superhydrophobic and conductive coating shows a high gauger factor(up to 7631 with the strain from 44%to 50%)and outstanding recyclability.The strain sensor could monitor different body joint motions with the stable and reliable sensing signals even after long time treatment in a corrosive solution. | Ling Wang Lisheng Wu Yuqing Wang Junchen Luo Huaiguo Xue Jiefeng Gao | 2022 | Nano Materials Science2022，4，2： | 2 |

| 8 | Picea species from humid continental and temperate marine climates perform better in monsoonal areas of middle latitudes of China显示文摘Picea spp.are a prominent component of the boreal,montane,and sub-alpine forests in the Northern Hemisphere,and have substantial economic importance due to their high quality fibre.However,performance and wood properties of the genus have not been systematically evaluated in China.This study aimed to examine genetic variations in growth traits,phenology,and wood properties of 17 Picea species,(three from North America,two from Europe,and 12 from China),in response to specific climate factors using a randomized complete block design in a monsoonal,middle latitude area of China.Results show that all growth traits and wood properties significantly varied among species(P <0.00).Of the 17 species examined,P.abies and P.pungens were the tallest with heights of 2.5 and 1.9 m at 9 years old,respectively,90% and 50% greater than the average heights.Branch length,number,and angles of both P.abies and P.pungens were greater than those of the other species.Heights of P.glauca and P.omorika were20-33% greater than the average.Fast-growing species had high quantities of first lateral branches and large top whorl branch lengths.The taller species exhibited greater tracheid lengths and average tracheid lengths to radial central diameter ratios(TL/R_D2),but smaller cell wall thicknesses to tracheid radial lumen diameter ratios(WT/R_D1),which is favorable for pulp production.Correlation analysis revealed that height and ring width had significant positive correlations with latitude but strongly negative correlations with longitude.Height was positively correlated with average annual rainfalls,but negative correlations with average yearly sunshine.Due to the increased average annual sunshine at the China test site relative to the seed source,species such as P.abies,P.pungens,P.glauca,and P.omorika from wet,humid areas performed better than native species.Considering similar temperatures,precipitation may be the main factor affecting growth,which is beneficial for predicting the extent of spruce expansion.These results should encourage further testing and provide reference information for future exotic species studies in this part of China. | Fangqun Ouyang Jianwei Ma Junchen Wang Lisheng Kong Hanguo Zhang Mulualem Tigabu Junhui Wang | 2021 | Journal of Forestry Research2021，32，4： | 1 |
| 9 | Analytical and Experimental Study of Free Vibration of Beams Carrying Multiple Masses and Springs显示文摘The structures in engineering can be simplified into elastic beams with concentrated masses and elastic spring supports. Studying the law of vibration of the beams can be a help in guiding its design and avoiding resonance. Based on the Laplace transform method, the mode shape functions and the frequency equations of the beams in the typical boundary conditions are derived. A cantilever beam with a lumped mass and a spring is selected to obtain its natural frequencies and mode shape functions. An experiment was conducted in order to get the modal parameters of the beam based on the NExT-ERA method. By comparing the analytical and experimental results, the effects of the locations of the mass and spring on the modal parameter are discussed. The variation of the natural frequencies was obtained with the changing stiffness coefficient and mass coefficient, respectively. The findings provide a reference for the vibration analysis methods and the lumped parameters layout design of elastic beams used in engineering. | Zhuang Wang Ming Hong Junchen Xu Hongyu Cui | 2014 | Journal of Marine Science and Application2014，13，1： | 1 |
| 10 | Kinematic mechanism and path planning of the Essboard显示文摘In this paper, we study the kinematic mechanism and path planning for a two-caster nonholonomic vehicle (the Essboard) which is a recent variant of skateboard. Different from the most studied Snakeboard, the Essboard consists of a torsion bar and two platforms, each of which contains a pedal and a caster. We first investigate the relationship between the tilt angles of the pedals and the wheel directions of the casters. This relationship reveals how to control the wheel directions by adjusting the tilt angles. Next, the rotational radius of the Essboard is derived for a given pair of tilt angles of both pedals. The rotational radius of the Essboard is much different than that of the Snakeboard. Then we develop a path-planning algorithm for the Essboard to move from a start position to the goal, using a series of consecutively connected arcs, which are tangent to each other at the connected points. It is shown from a kinematic point of view that the path planning of the Essboard can be solved by a series of pairs of pedals' tilt angles. Three experiments are conducted to confirm the correctness of the main results. The results in this paper are a foundation for further study of the Essboard. | SU BaiQuan WANG TianMiao WANG JunChen KUANG ShaoLong | 2013 | Science China(Technological Sciences)2013，56，6： | 1 |
| 11 | Ten-Hour Stable Noninvasive Brain-Computer Interface Realized by Semidry Hydrogel-Based Electrodes显示文摘Noninvasive brain computer interface(BCI)has been extensively studied from many aspects in the past decade.In order to broaden the practical applications of BCI technique,it is essential to develop electrodes for electroencephalogram(EEG)collection with advanced characteristics such as high conductivity,long term efectiveness,and biocompatibility.In this study,we devcloped a silver-nanowire/PVA hydrogc/mclamine sponge(AgPHMS)semidry EEG electrode for long lasting monitoring of EEG signal.Benefiting from the water storage capacity of PVA hydrogel,the clectrolyte solution can be continuously released to the scalpelctrode interface during used.The electrolyte solution can infiltrate the stratum corneum and reduce the scalp-electrode impedance to 10k0-15k0.The flexible structure enabls the electrode with mechanical stability,increases the wearing comfort,and reduces the scalp-electrode gap to reduce contact impedance.As a result,a long-term BCI application based on measurements of motion-onset visual evoked potentials(mVEPs)shows that the 3-hour BCI accuracy of the new electrode(77%to 100%)is approximately the same as that of conventional eletrodes supported by a conductive gel during the first hour.Furthermore,the BCI system based on the new electrode can retain low contact impedance for 10 hours on scalp,which greatly improved the ability of BCI technique. | Junchen Liu Sen Lin Wenzheng Li Yanzhen Zhao Dingkun Liu Zhaofeng He Dong Wang Ming Lei Bo Hong Hui Wu | 2022 | Research2022，，2： | 1 |
| 12 | On high-performance rotational energy harvesting with a novel cam-like dielectric elastomer generator显示文摘Rotational energy is a type of common energy source that can be harvested for supplying low-powered electronic devices.This paper proposes and investigates a novel cam-like dielectric elastomer generator(CDEG)for high-performance rotational energy harvesting.A mushroom-head clamp is designed to form a type of advanced conical dielectric elastomer membranes(DEMs).Moreover,a type of multi-protrusion cam mechanism is designed in the CDEG to effectively convert any external rotational excitation into a linear reciprocating motion,which can be further converted into electricity through the DEMs.First,the operating principle of the system under external rotational excitation is analyzed theoretically by deducing the deformation condition of the DEMs and the electrical output of the system.Second,the prototype is fabricated,and the rotational-to-linear motion conversion rule of its cam-like mechanism and the DEM capacitance calculation approach are validated.The experimental results show that adequate charging time and discharging time of the DEMs,which can be realized through the proposed cam-like mechanisms,are beneficial to the energy harvesting(EH)performance of the system.Third,with the validated theoretical model,numerical simulations are conducted to further study the system dynamics and the influences of important system parameters on the EH performance to provide a guideline for system improvement.Finally,the genetic algorithm is adopted to obtain the optimal system parameters and the corresponding electrical output of the proposed CDEG,demonstrating its superior output power at ultralow rotational frequencies compared with other typical rotational energy harvesters in the literature. | FANG ShiTong WANG ShuaiBo ZHANG GuoQing WANG Chen XU JunChen WANG ZhouZhou FENG AiJie QIAO ZiJian YURCHENKO Daniil LAI ZhiHui | 2023 | Science China(Technological Sciences)2023，66，5： | 0 |
| 13 | A large-area AgNW-modified textile with high-performance electromagnetic interference shielding显示文摘Manufacturing a flexible,light,large-area,and high-efficiency electromagnetic shielding materials in a straightforward and cost-effective manner presently remains a significant challenge.In this work,we propose a conductive network design and verify its electromagnetic interference(EMI)shielding effectiveness(SE)by simulation.Using the structure and parameters obtained by simulation,we prepare a flexible EMI shielding material using silver nanowires(AgNWs)/polyvinyl butyral(PVB)ethanol solution and textile substructure via a facile immersing method.In the frequency range of 5-18 GHz,the AgNWs/PVB textile with 1.4 mm thickness achieves an EMI SE of 59 dB,which exceeds the requirements for commercial applications.Due to the low density of 56 mg/cm^(3),specific shielding effectiveness(SSE)of this material reaches 1053 dB m^(3)/g.It is found that the AgNWs/PVB textile is more resistant to washing with water and oxidation than AgNWs textile without a PVB protector.As a result,the conductivity of AgNWs/PVB textile exhibits no change after washing with water and varies slightly after being kept in hot air.We find that a signal monitor is unable to detect a signal emitted by a mobile phone from a jacket lined with AgNWs/PVB textile.AgNWs/PVB textile with these properties can be mass-produced as high-efficiency EMI shielding material for commercial applications. | Junchen Liu Sen Lin Kai Huang Chao Jia Qingmin Wang Ziwei Li Jianan Song Zhenglian Liu Haiyang Wang Ming Lei Hui Wu | 2020 | npj Flexible Electronics2020，4，1： | 0 |
| 14 | Relationship of Microchannels and Plaque Erosion in Patients with ST-Segment Elevation Myocardial Infarction: An Optical Coherence Tomography Study显示文摘Objective:Microchannels are associated with the progression of atherosclerotic vulnerable plaques.However,in patients with culprit optical coherence tomography(OCT)-defined plaque erosion,the knowledge of microchannels and culprit lesion vulnerability is limited.The aim of this study was to investigate culprit lesion characteristics in patients with ST-segment elevated myocardial infarction(STEMI)caused by plaque erosion with and without microchannels using OCT.Methods:In all,348 STEMI patients with plaque erosion who underwent OCT of the culprit lesion at the 2nd Affiliated Hospital of Harbin Medical University(Harbin,China)from August 2014 to December 2017 were included and divided into the microchannel group(n=116,33.3%)and no-microchannel group(n=232,66.7%).The clinical characteristics and OCT-derived plaque features were compared between both groups.Results:Among the 348 STEMI patients with plaque erosion,culprit lesions with microchannels had higher incidence of lipid plaque(59.5%vs.45.3%,P=0.012);calcification(41.4%vs.24.6%,P=0.002);spotty calcification(30.2%vs.18.1%,P=0.014);macrophages accumulation(72.4%vs.45.7%,P<0.001);and cholesterol crystals(32.8%vs.14.2%,P<0.001)than those without microchannels.In addition,minimal lumen area was smaller((1.9±0.9)mm2 vs.(2.8±2.3)mm2,P<0.001)and lumen area stenosis was greater((71.3%±13.4%)vs.(65.3%±19.3%),P=0.001)in the microchannel group than in the no-microchannel group.Conclusion:In patients with STEMI caused by plaque erosion,one-third manifested typical microchannel characteristics,and those with microchannels were associated with more severe luminal stenosis and more vulnerable plaque features than those without microchannels. | Senqing Jiang Junchen Guo Yanwei Yin Chao Fang Jifei Wang Yidan Wang Fangmeng Lei Sibo Sun Xueying Pei Ruyi Jia Shaotao Zhang Lulu Li Yini Wang Lei Xing Huai Yu Huimin Liu Maoen Xu Xuefeng Ren Lijia Ma Guo Wei Jingbo Hou Jiannan Dai Bo Yu | 2022 | Cardiology Discovery2022，2，2： | 0 |
| 15 | Computational prediction and functional analysis of arsenic-binding proteins in human cells显示文摘Background:Arsenic has a broad anti-cancer ability against hematologic malignancies and solid tumors.To systematically understand the biological functions of arsenic,we need to identify arsenic-binding proteins in human cells.However,due to lack of effective theoretical tools and experimental methods,only a few arsenic-binding proteins have been identified.Methods:Based on the crystal structure of ArsM,we generated a single mutation free energy profile for arsenic binding using free energy perturbation methods.Multiple validations provide an indication that our computational model has the ability to predict arsenic-binding proteins with desirable accuracy.We subsequently apply this computational model to scan the entire human genome to identify all the potential arsenic-binding proteins.Results:The computationally predicted arsenic-binding proteins show a wide range of biological functions,especially in the signaling transduction pathways.In the signaling transduction pathways,arsenic directly binds to the key factors(e.g.,Notch receptors,Notch ligands,Wnt family proteins,TGF-beta,and their interacting proteins)and results in significant inhibitions on their enzymatic activities,further having a crucial impact on the related signaling pathways.Conclusions:Arsenic has a significant impact on signaling transduction in cells.Arsenic binding to proteins can lead to dysfunctions of the target proteins,having crucial impacts on both signaling pathway and gene transcription.We hope that the computationally predicted arsenic-binding proteins and the functional analysis can provide a novel insight into the biological functions of arsenic,revealing a mechanism for the broad anti-cancer of arsenic. | Shichao Pang Junchen Yang Yilei Zhao Yixue Li Jingfang Wang | 2019 | Quantitative Biology2019，7，3： | 0 |
| 16 | Themis suppresses the effector function of CD8^(+)T cells in acute viral infection显示文摘CD8^(+)T cells play a central role in antiviral immune responses.Upon infection,naive CD8^(+)T cells differentiate into effector cells to eliminate virus-infected cells,and some of these effector cells further differentiate into memory cells to provide long-term protection after infection is resolved.Although extensively investigated,the underlying mechanisms of CD+T-cell differentiation remain incompletely understood.Themis is a T-cell-specific protein that plays critical roles in T-cell development.Recent studies using Themis T-cell conditional knockout mice also demonstrated that Themis is required to promote mature CD8^(+)T-cell homeostasis,cytokine responsiveness,and antibacterial responses.In this study,we used LCMV Armstrong infection as a probe to explore the role of Themis in viral infection.We found that preexisting CD8^(+)T-cell homeostasis defects and cytokine hyporesponsiveness do not impair viral clearance in Themis T-cell conditional knockout mice.Further analyses showed that in the primary immune response,Themis deficiency promoted the differentiation of CD8^(+)effector cells and increased their TNF and IFNy production.Moreover,Themis deficiency impaired memory precursor cell(MPEC)differentiation but promoted short-lived effector cell(SLEC)differentiation.Themis deficiency also enhanced effector cytokine production in memory CD8^(+)T cells while impairing central memory CD8^(+)T-cell formation.Mechanistically,we found that Themis mediates PD-1 expression and its signaling in effector CD8^(+)T cells,which explains the elevated cytokine production in these cells when Themis is disrupted. | Jian Tang Xian Jia Jian Li Junchen Dong Jiayu Wang Wanyun Li Yuzhen Zhu Yanyan Hu Bowen Hou Chunjie Lin Yu Cong Tong Ren Changsheng Yan Hongying Yang Qian Lai Haiping Zheng Yuzhou Bao Namrata Gautam Hong-Rui Wang Bing Xu Xiao Lei Chen Qing Li Nicholas R.J.Gascoigne Guo Fu | 2023 | Cellular & Molecular Immunology2023，20，5： | 0 |
| 17 | A new member of Sphenopsida,Neolobatannularia gen. nov. from Late Triassic of western Liaoning,China显示文摘A new genus Neolobatannularia Sun et Li gen. nov. with the type species Neolobatannularia liaoningensis Sun et Li sp. nov. from the Upper Triassic Yangcaogou Formation of Beipiao, Liaoning, China, is described in this paper. The new taxon is attributed to Equisetales of Sphenopsida based on its branch with internodes, node and leaves borne in whorls on nodes. It is a new member of the Mesozoic Sphenopsida. Although the new taxon shares some morphological characters with the genus Lobatannularia Kawasaki, a genus widely distributed in the Permian Cathaysia flora in East Asia, and the genus Lobatannulariopsis Yang from the Late Triassic of southwestern China, its unique branching pattern is markedly distinguished from the two known genera. Some Triassic known species of Lobatannularia may belong to the present new genus Neolobatannularia. | WANG Junyou LI Tao LIU Zhiping GUO Bin KANG Ai NA Yuling LI Yunfeng WANG Hongshan BO Junchen SUN Chunlin | 2019 | Global Geology2019，22，1： | 0 |
| 18 | Risk factors of major intraoperative blood loss at primary debulking surgery for ovarian cancer显示文摘Objective:The goal of this study was to find the risk factors for major intraoperative blood loss(MBL)of pr imary debulking surgery(PDS)for ovarian cancer.Methods:Patients wi th ovarian cancer who underwent PDS in our hospital,from 2010 to 2017,were enrolled.The association between risk factors and MBL was modeled with the use of logisde regr ession.Receiver operating characteristic(ROC)curve analysis was used to determine the predictive value of the logi stic regression model.Results:A total of 346 padients met the inclusion criteria.There were 150 patients with MBL.Tumor stage 3/4(P<0.001),American Society of Aneshesiologists(ASA)score 23(P=0.044),ascites volume≥500 ml(P=0.002),radical or ultra radical surgery(P=0.002),and diabetes(P=0.035)were independent risk factors for MBL in patients with ovarian cancer.The logistic regression combined model of these five factors is more reliable in the prediction of MBL with an area under the ROC curve of 0.729 than the tumor stage(ROC curve=0.645)and surgical complexity(ROC curve=0.568).Conclusion:In padients with ovarian cancer,five risk factors for major intraoperative bleeding were identified.Planned surgical procedures and preoperative risk factors can be used to predict perioperative blood requir ements. | Sha Dou Junchen Chen Yuanfen Wang Chongyuan Zhu Heng Cui Yi Li | 2022 | Gynecology and Obstetrics Clinical Medicine2022，2，1： | 0 |

| 20 | Yellow-Fluorescence Carbon Dots Employed for pH Sensing and Detection of Tigecycline显示文摘Long-wavelength fluorescence carbon dots (CDs) show great importance in multiple fields,especially for the biochemical sensing.Here,we proposed one type of CDs doped with nitrogen and sulfur through the hydrothermal method,which exhibited obvious yellow-fluorescence in aqueous solution.Importantly,the fluorescence intensity of CDs decreased with pH decreasing in the acidic range,thus a linear relationship between pH and fluorescence intensity was established,exhibiting the potential of pH sensing.Additionally,introducing tigecycline into CDs resulted in their decreased fluorescence,thus,we further established a strategy of detecting tigecycline with the concentration range of 200 μM to 7 nM.Meanwhile,we elucidated the static quenching as the major mechanism for CDs responding tigecycline,which was induced by the formed new complex between CDs and tigecycline.Furthermore,the practicality of the method was verified by examining the recovery of tigecycline in the actual lake-water samples. | Jingwen Zhao Junchen Wang Linggao Zeng Sen Zhou Xiaoming Yang | 2023 | Chinese Journal of Chemistry2023，41，24： | 0 |
