| 1 | Influence of Humidity and Air Pressure on the Ion Mobility Based on Drift Tube Method显示文摘The measurement of ion mobility is important for calculating the corona loss of the transmission lines,and for establishing corona loss and ion current models that take humidity and air pressure into consideration.This paper describes a needle-ring corona discharge experiment setup based on a prior study,which simulates different humidity and air pressure conditions;it is observed that the execution of the ion gate is improved in this experiment from off-on-off to off-on to achieve higher ion current amplitude.Additionally,positive and negative ion mobility under different humidity and air pressure is obtained,with the positive ion mobility measurements in the range of 1.1126 to 1.9167 cm2/V·s,and the negative ion mobility measurements in the range of 1.3574 to 2.5643 cm2/V·s.The experimental results indicate that ion mobility decreases nonlinearly with increase in humidity,but trends towards saturation in the 30%–70%relative humidity range.Finally,a parameter correction method for calibrating the relationship among the ion mobility,humidity,and air pressure is proposed. | Yunpeng Liu Shilong Huang Lei Zhu | 2015 | CSEE Journal of Power and Energy Systems2015，1，3： | 8 |

| 4 | A Heterogeneous Information Fusion Deep Reinforcement Learning for Intelligent Frequency Selection of HF Communication显示文摘The high-frequency(HF) communication is one of essential communication methods for military and emergency application. However, the selection of communication frequency channel is always a difficult problem as the crowded spectrum, the time-varying channels, and the malicious intelligent jamming. The existing frequency hopping, automatic link establishment and some new anti-jamming technologies can not completely solve the above problems. In this article, we adopt deep reinforcement learning to solve this intractable challenge. First, the combination of the spectrum state and the channel gain state is defined as the complex environmental state, and the Markov characteristic of defined state is analyzed and proved. Then, considering that the spectrum state and channel gain state are heterogeneous information, a new deep Q network(DQN) framework is designed, which contains multiple sub-networks to process different kinds of information. Finally, aiming to improve the learning speed and efficiency, the optimization targets of corresponding sub-networks are reasonably designed, and a heterogeneous information fusion deep reinforcement learning(HIF-DRL) algorithm is designed for the specific frequency selection. Simulation results show that the proposed algorithm performs well in channel prediction, jamming avoidance and frequency channel selection. | Xin Liu Yuhua Xu Yunpeng Cheng Yangyang Li Lei Zhao Xiaobo Zhang | 2018 | China Communications2018，15，9： | 6 |
| 5 | SARS-CoV-2 infection aggravates chronic comorbidities of cardiovascular diseases and diabetes in mice显示文摘Background:Cardiovascular diseases(CVDs)and diabetes mellitus(DM)are top two chronic comorbidities that increase the severity and mortality of COVID-19.However,how SARS-CoV-2 alters the progression of chronic diseases remain unclear.Methods:We used adenovirus to deliver h-ACE2 to lung to enable SARS-CoV-2 infection in mice.SARS-CoV-2’s impacts on pathogenesis of chronic diseases were studied through histopathological,virologic and molecular biology analysis.Results:Pre-existing CVDs resulted in viral invasion,ROS elevation and activation of apoptosis pathways contribute myocardial injury during SARS-CoV-2 infection.Viral infection increased fasting blood glucose and reduced insulin response in DM model.Bone mineral density decreased shortly after infection,which associated with impaired PI3K/AKT/mTOR signaling.Conclusion:We established mouse models mimicked the complex pathological symptoms of COVID-19 patients with chronic diseases.Pre-existing diseases could impair the inflammatory responses to SARS-CoV-2 infection,which further aggravated the pre-existing diseases.This work provided valuable information to better understand the interplay between the primary diseases and SARS-CoV-2 infection. | Yuanwu Ma Dan Lu Linlin Bao Yajin Qu Jiangning Liu Xiaolong Qi Lei Yu Xu Zhang Feifei Qi Qi Lv Yunpeng Liu Xudong Shi Caixian Sun Jing Li Jie Wang Yunlin Han Kai Gao Wei Dong Ning Liu Shan Gao Jing Xue Qiang Wei Sidan Pan Hong Gao Lianfeng Zhang Chuan Qin | 2021 | Animal Models and Experimental Medicine2021，4，1： | 3 |
| 6 | Relationships Between Parenting Style, Self-Perception and Shyness Among Chinese Early Adolescents显示文摘The current study investigated the parenting style, self-perception, and shyness level of 1,338 junior high school students, so as to explore relationships between these variables. Results indicated that (1) The levels of the unassuming shyness, shyness when facing negative evaluation are higher than other dimensions of shyness; (2) The acceptance/involvement and strictness/supervision are negatively related with shyness; the acceptance/participation and strictness/supervision are positively correlated with self-perception; self-perception was negatively related with shyness; and (3) Parents' acceptance/participation can indirectly affect shyness through the self-perception; parents' strictness/supervision can affect shyness directly and indirectly through the self-perception. | Chen YingMin, Wu YunPeng Zhang YuanJin Wang Peng Han Lei Gao FengQiang | 2014 | Psychology Research2014，4，11： | 3 |
| 7 | Key CO_(2)capture technology of pure oxygen exhaust gas combustion for syngas-fueled high-temperature fuel cells显示文摘Integrated gasification fuel cells(IGFCs)integrating high-temperature solid oxide fuel cell technology with CO_(2)capture processes represents highly-efficient power systems with negligible CO_(2)emissions.Flame burning with pure oxygen is an ideal method for fuel cell exhaust gas treatment,and this report describes experimental and numerical studies regarding an oxy-combustor for treating the exhaust gas of a 10 kW IGFC system anode.The applied simulation method was verified based on experiments,and the key performance indices of the combustor were studied under various conditions.It was determined that 315 K was the ideal condensation temperature to obtain flame stability.Under these pure oxygen flame burning conditions,CO was almost completely converted,and the dry mole fraction of CO_(2)after burning was C 0.958 when there was up to 5%excess O_(2).Overall,5%excess O_(2)was recommended to maximize CO_(2)capture and promote other environmental considerations.Additionally,the optimal tangential fuel jet angle to control the liner temperature was approximately 25°.The total fuel utilization had to be high enough to maintain the oxygen flame temperature of the anode exhaust gas below 1800 K to ensure that the system was environmentally friendly.The results presented herein have great value for designing IGFCs coupled with CO_(2)capture systems. | Hanlin Wang Qilong Lei Pingping Li Changlei Liu Yunpeng Xue Xuewei Zhang Chufu Li Zhibin Yang | 2021 | International Journal of Coal Science & Technology2021，8，3： | 3 |
| 8 | Review on strategies of space-based optical space situational awareness显示文摘Space-based optical(SBO)space surveillance has attracted widespread interest in the last two decades due to its considerable value in space situation awareness(SSA).SBO observation strategy,which is related to the performance of space surveillance,is the top-level design in SSA missions reviewed.The recognized real programs about SBO SAA proposed by the institutions in the U.S.,Canada,Europe,etc.,are summarized firstly,from which an insight of the development trend of SBO SAA can be obtained.According to the aim of the SBO SSA,the missions can be divided into general surveillance and space object tracking.Thus,there are two major categories for SBO SSA strategies.Existing general surveillance strategies for observing low earth orbit(LEO)objects and beyond-LEO objects are summarized and compared in terms of coverage rate,revisit time,visibility period,and image processing.Then,the SBO space object tracking strategies,which has experienced from tracking an object with a single satellite to tracking an object with multiple satellites cooperatively,are also summarized.Finally,this paper looks into the development trend in the future and points out several problems that challenges the SBO SSA. | HU Yunpeng LI Kebo LIANG Yan’gang CHEN Lei | 2021 | Journal of Systems Engineering and Electronics2021，32，5： | 3 |
| 9 | Trimetallic oxyhydroxides as active sites for large-current-density alkaline oxygen evolution and overall water splitting显示文摘Earth-abundant electrocatalysts for large-current-density water splitting under alkaline condition are desirable.Oxygen evolution reaction,which is a bottleneck of the overall water splitting,faces the problems of complicated reconstruction and deficiency in rational design of active sites.Herein,we report a series of transition metal chalcogenides for alkaline OER.Among them,FeCoNi(S)displayed a low overpotential of 293 m V to deliver a current density of 500 m A cm^(-2),which is in the top level of non-precious metal based OER electrocatalysts.A combination of(ex)in situ characterizations and DFT calculation shows that Ni(Fe,Co)trimetallic oxyhydroxides were the active sites for highly-efficient OER.Furthermore,for FeCoNi(S),when used as a bifunctional catalyst for water splitting,it only required a cell voltage of 1.84 V to deliver~500 m A cm^(-2) with extraordinary long-term stability over 2000 h.This work provides the comprehension of high-efficiency,robust catalysts for OER and overall water splitting at large current densities in alkaline media. | Lei Chen Yunpeng Wang Xin Zhao Yuchao Wang Qian Li Qichen Wang Yougen Tang Yongpeng Lei | 2022 | Journal of Materials Science & Technology2022，，15： | 3 |
| 10 | Radiation-hardened property of single-walled carbon nanotube film-based field-effect transistors under low-energy proton irradiation显示文摘Strong C-C bonds,nanoscale cross-section and low atomic number make single-walled carbon nanotubes(SWCNTs)a potential candidate material for integrated circuits(ICs)applied in outer space.However,very little work combines the simulation calculations with the electrical measurements of SWCNT field-effect transistors(FETs),which limits further understanding on the mechanisms of radiation effects.Here,SWCNT film-based FETs were fabricated to explore the total ionizing dose(TID)and displacement damage effect on the electrical performance under low-energy proton irradiation with different fluences up to 1×1015 p/cm2.Large negative shift of the threshold voltage and obvious decrease of the on-state current verified the TID effect caused in the oxide layer.The stability of the subthreshold swing and the off-state current reveals that the displacement damage caused in the CNT layer is not serious,which proves that the CNT film is radiation-hardened.Specially,according to the simulation,we found the displacement damage caused by protons is different in the source/drain contact area and channel area,leading to varying degrees of change for the contact resistance and sheet resistance.Having analyzed the simulation results and electrical measurements,we explained the low-energy proton irradiation mechanism of the CNT FETs,which is essential for the construction of radiation-hardened CNT film-based ICs for aircrafts. | Xiaorui Zhang Huiping Zhu Song’ang Peng Guodong Xiong Chaoyi Zhu Xinnan Huang Shurui Cao Junjun Zhang Yunpeng Yan Yao Yao Dayong Zhang Jingyuan Shi Lei Wang Bo Li Zhi Jin | 2021 | Journal of Semiconductors2021，42，11： | 2 |
| 11 | Prognostic significance of periostin in colorectal cancer显示文摘Accumulating evidence suggests that periostin is frequently upregulated in tissue injury, inflammation,fibrosis and tumor progression. Periostin expression in cancer cells can promote metastatic potential of colorectal cancer(CRC)via activating PI3 K/Akt signaling pathway. Moreover, periostin is observed mainly in tumor stroma and cytoplasm of cancer cells, which may facilitate aggressiveness of CRC. In this review, we summarize information regarding periostin to emphasize its role as a prognostic marker of CRC. | Xingming Deng Sheng Ao Jianing Hou Zhuofei Li Yunpeng Lei Guoqing Lyu | 2019 | Chinese Journal of Cancer Research2019，31，3： | 2 |
| 12 | SARS-CoV-2 impairs the disassembly of stress granules and promotes ALS-associated amyloid aggregation显示文摘The nucleocapsid(N)protein of SARS-CoV-2 has been reported to have a high ability of liquid-liquid phase separation,which enables its incorporation into stress granules(SGs)of host cells.However,whether SG invasion by N protein occurs in the scenario of SARS-CoV-2 infection is unknow,neither do we know its con-sequence.Here,we used SARS-CoV-2 to infect mam-malian cells and observed the incorporation of N protein into SGs,which resulted in markedly impaired self-dis-assembly but stimulated cell cellular clearance of SGs.NMR experiments further showed that N protein binds to the SG-related amyloid proteins via non-specific tran-sient interactions,which not only expedites the phase transition of these proteins to aberrant amyloid aggre-gation in vitro,but also promotes the aggregation of FUS with ALS-associated P525L mutation in cells.In addition,we found that ACE2 is not necessary for the infection of SARS-CoV-2 to mammalian cells.Our work indicates that SARS-CoV-2 infection can impair the dis-assembly of host SGs and promote the aggregation of SG-related amyloid proteins,which may lead to an increased risk of neurodegeneration. | Yichen Li Shuaiyao Lu Jinge Gu Wencheng Xia Shengnan Zhang Shenqing Zhang Yan Wang Chong Zhang Yunpeng Sun Jian Lei Cong Liu Zhaoming Su Juntao Yang Xiaozhong Peng Dan Li | 2022 | Protein & Cell2022，13，8： | 1 |

| 14 | Enriched endoplasmic reticulum-mitochondria interactions result in mitochondrial dysfunction and apoptosis in oocytes from obese mice显示文摘Background: Maternal obesity alters oocytes and subsequent fetal metabolism. An increasing number of studies have shown that the endoplasmic reticulums(ER) or mitochondria have important effects on oocyte quality, but there has been no study of the effect of mitochondria-associated ER membranes(MAMs) on oocyte quality. The present study was designed to assess whether the level of MAM and MAM-related proteins were different in oocytes from obese and control mice.Results: First, oocytes from mice with high-fat-diet(HFD)-induced obesity had higher levels(either greater numbers or a higher proportion for the same numbers) of MAM than oocytes from control mice. The abundance of MAM-related proteins in oocytes from obese mice was significantly greater at both the messenger RNA and protein levels, including inositol 1,4,5-trisphosphate receptor, type 1(IP3R1), inositol 1,4,5-trisphosphate receptor,type 2(IP3 R2) and phosphofurin acidic cluster sorting protein 2(PACS-2). Further, there was an increase in mitochondrial Ca^(2+)([Ca^(2+)]_m) which was associated with increased apoptosis and compromised cytoplasmic maturation in oocytes from obese mice. Down-regulation of MAM-related protein IP3R1 in oocytes from obese mice decreased [Ca^(2+)]_mand apoptosis and improved cytoplasmic maturation but did not reduce the overal MAM level. However, down-regulating MAM-related protein PACS-2 in oocytes from obese mice did reduce the level of MAM and [Ca^(2+)]_m, which decreased the rate of apoptosis and improved cytoplasmic maturation of oocytes from obese mice.Conclusions: It is possible that enriched MAM could increase [Ca^(2+)]_m, and this increase has been found to be associated with increased apoptosis and compromised cytoplasmic maturation in oocytes from obese mice. This finding suggests a novel therapeutic target for obesity-induced oocyte defects. | Lihong Zhao Tengfei Lu Lei Gao Xiangwei Fu Shien Zhu Yunpeng Hou | 2018 | Journal of Animal Science and Biotechnology2018，9，1： | 1 |
| 15 | 北半球高山和极地虎耳草属物种丰富度的地理格局:温度和生境异质性的作用显示文摘现代气候、生境异质性和长期气候变化对森林生态系统中分布的木本植物的物种丰富度格局的影响在以往研究中受到广泛关注,但对高寒-极地生态系统中的草本植物物种丰富度格局及其影响因素的研究仍较少。本研究旨在检验以往研究中基于物种丰富度和环境因子关系提出的假说是否能够解释高寒-极地地区典型草本植物-虎耳草属(Saxifraga)的物种丰富度格局。本研究利用全球437种虎耳草属物种分布数据,探讨了全部物种、广域和狭域物种丰富度格局的影响因素。采用广义线性模型和空间自回归模型,评估了现代气候、生境异质性和历史气候对虎耳草属物种丰富度格局的影响。采用偏回归分析了不同变量对物种丰富度的独立解释率和共同解释率,并检验了4种广泛使用的物种丰富度与环境关系模型对物种丰富度格局的解释能力。研究结果表明,温度与虎耳草属所有物种和广域物种的物种丰富度格局呈显著负相关关系,是影响物种丰富度格局最重要的环境因子,这可能反映了虎耳草属对其祖先温带生态位的保守性。生境异质性和末次冰期以来的气候变化是虎耳草属狭域物种丰富度空间变异的最佳预测因子。总体而言,包含5个预测变量的组合模型可以解释大约40%–50%的虎耳草属物种丰富度的空间变异。此外,进化和生物地理过程在虎耳草属物种丰富度格局形成方面可能发挥了重要作用,这有待进一步研究。 | Lian Liu Xiaoting Xu Lei Zhang Yaoqi Li Nawal Shrestha Danilo M.Neves Qinggang Wang Hong Chang Xiangyan Su Yunpeng Liu Jianyong Wu Dimitar Dimitrov Zhiheng Wang Jianquan Liu | 2022 | Journal of Plant Ecology2022，15，2： | 1 |

| 17 | Small-angle X-ray scattering study on the orientation of suspended sodium titanate nanofiber induced by applied electric field显示文摘Introduction Nanofiber orientation in suspensions determines the performance of nanoparticle suspensions which have potential applications in intelligent control.Material and method Na2Ti3O7 nanofibers were prepared with a hydrothermal method.The orientation degree of Na2Ti3O7 nanofibers in silicone oil has been studied by in situ small-angle X-ray scattering technique.Thünemann–Ruland method was used to extract the distribution widths of Na2Ti3O7 nanofibers in the suspensions.Conclution An empirical formula has been proposed to describe the dependence of nanofiber orientation degree on the external electric-field strength(E)and the nanofiber concentration(C).The results demonstrate that the response of nanofiber orientation to the electric field can be divided into exponential and linear stages before and after the inflection point of electric-field strength(Ec0.09 kV/mm).Low concentration of suspension is more sensitive to the external electric field.The increase in nanofiber concentration will decrease the response sensitivity of nanofiber orientation degree to the change of E.The critical concentration of Na2Ti3O7 nanofibers in the suspension is about 5 wt%.This study is expected to give new clue for the structurally responsive mechanism of anisotropic nanoparticles in suspensions to electric-field strength and particle concentration. | Jiayi Wang Xiaoyi Zhao Yunpeng Liu Lixiong Qian Lei Yao Xueqing Xing Guang Mo Quan Cai Zhongjun Chen Zhonghua Wu | 2019 | Radiation Detection Technology and Methods2019，3，3： | 1 |
| 18 | Metamorphism and geochronology of garnet amphibolite from the Beishan Orogen,southern Central Asian Orogenic Belt:Constraints from P-T path and zircon U-Pb dating显示文摘Numerous lenses of garnet amphibolite occur in the garnet-bearing biotite-plagioclase gneiss belt in the Baishan area of the Beishan Orogen,which connects the Tianshan Orogen to the west and the Mongolia-Xing’anling Orogen to the east.The study of metamorphism in Beishan area is of great significance to explain the tectonic evolution of Beishan orogen.According to the microstructures,mineral relationships,and geothermobarometry,we identified four stages of mineral assemblages from the garnet amphibolite sample:(1) a pre-peak stage,which is recorded by the cores of garnet together with core-inclusions of plagioclase(Pl1);(2) a peak stage,which is recorded by the mantles of garnet together with mantle-inclusions of plagioclase(Pl2)+amphibole(Amp1)+Ilmenite(Ilm1)+biotite(Bt1),developed at temperature-pressure(P-T) conditions of 818.9-836.5℃ and7.3-9.2 kbar;(3) a retrograde stage,which is recorded by garnet rims + plagioclase(Pl3)+amphibole(Amp2)+orthopyroxene(Opx1)+biotite(Bt2)+Ilmenite(Ilm2),developed at P-T conditions of 796.1-836.9℃ and5.6-7.5 kbar;(4) a symplectitic stage,which is recorded by plagioclase(Pl4)+orthopyroxene(Opx2)+amphibole(Amp3)+biotite(Bt3) symplectites,developed at P-T conditions of 732 ±59.6℃ and 6.1 ±0.6 kbar.Moreover,the U-Pb dating of the Beishan garnet amphibolite indicates an age of 301.9 ±4.7 Ma for the protolith and 281.4±8.5 Ma for the peak metamorphic age.Therefore,the mineral assemblage,P-T conditions,and zircon U-Pb ages of the Beishan garnet amphibolite define a near-isothermal decompression of a clockwise P-T-t(Pressure-Temperature-time) path,indicating the presence of over thickened continental crust in the Huaniushan arc until the Early Permian,then the southern Beishan area underwent a process of thinning of the continental crust. | Wenbin Kang Wei Li Lei Kang Yunpeng Dong Dazhi Jiang Jiwei Liang Haoqiang Dong | 2020 | Geoscience Frontiers2020，11，4： | 0 |
| 19 | A novel SAXS/XRD/XAFS combined technique for in-situ timeresolved simultaneous measurements显示文摘Synchrotron radiation based combined technique can provide multiple structural information simultaneously,which is an important development direction of structural detection.In this study,a novel small-angle X-ray scattering/X-ray diffraction/X-ray absorption fine structure(SAXS/XRD/XAFS)combined setup was constructed,where an area detector,a curved detector,and a point detector are,respectively,used for the measurements of SAXS,XRD,and XAFS signals.A detailed description about the combined setup was given.A minitype diamond detector coupled to a SAXS beamstop was used to record the transmitted X-ray intensity,making the scattering(SAXS and XRD)signal measurement compatible with the absorption(XAFS)signal measurement,avoiding mechanical switching.The two-way sampling strategy was used to acquire XAFS signals,shortening the non-counting time.The two-way and one-way sampling strategies were discussed.High-frequency sampling scheme was used to collect experimental signals,improving the measurement efficiency and signal-to-noise ratio.A detailed description and discussion about the high-frequency scheme were also given in this paper.Except the rotation of monochromator,there is no mechanical movement in measurements,time resolution may reach the level of seconds.Using this SAXS/XRD/XAFS combined setup,SAXS,XRD,and XAFS signals can be acquired simultaneously.With some in-situ sample environment system,the newlydeveloped combined technique can be used to track the structure evolution in complex fluids.During the formation processes of(BiO)2CO3 and ZnAPO-34 particles,the changes of in-situ experimental data with reaction time demonstrate that SAXS/XRD/XAFS combined technique is feasible to track the dynamic process. | Zhonghua Wu Yunpeng Liu Xueqing Xing Lei Yao Zhongjun Chen Guang Mo Lirong Zheng Quan Cai Hao Wang Jiajun Zhong Yuecheng Lai Lixiong Qian | 2023 | Nano Research2023，16，1： | 0 |
| 20 | Design and high-strength origin of novel (CoFeNi)_(80)Ti_(5)V_(15) medium entropy alloy with “fcc + L1_(2) ”structure显示文摘1.Introduction The multi-component high entropy alloys(HEAs)or medium entropy alloys(MEAs)attract reseachers’extensive attention,in particular,the single-face center cubic(fcc)HEAs or MEAs due to their some advantages,such as excellent ductility[1,2],good corrosion resistance[3]and high radiation tolerance[4].However,their strength is commonly insufficient for engineering applica-tions.Recently,many investigations are ongoing to improve their strength by traditional strengthening mechanisms,like fine-grained strengthening[5,6],solid strengthening[6-8],strain strengthening[9],polyphase strengthening[10-12],and precipitation strength-ening[13-15].Among these strengthening mechanisms,the co-herent L1_(2)-type nanoparticles precipitation strengthening has been proven to be a very effective way to improve their strength[13-15]. | Lei Wang Xinyuan Wu Yuan Wu Gang Liu Zhenhua Han Yunpeng Zhang Yanning Su Shengfeng Kang Jun Shen Guojun Zhang | 2023 | Journal of Materials Science & Technology2023，，18： | 0 |
