| 1 | Divergent Projection Patterns Revealed by Reconstruction of Individual Neurons in Orbitofrontal Cortex显示文摘The orbitofrontal cortex(OFC)is involved in diverse brain functions via its extensive projections to multiple target regions.There is a growing understanding of the overall outputs of the OFC at the population level,but reports of the projection patterns of individual OFC neurons across different cortical layers remain rare.Here,by combining neuronal sparse and bright labeling with a whole-brain florescence imaging system(fMOST),we obtained an uninterrupted three-dimensional whole-brain dataset and achieved the full morphological reconstruction of 25 OFC pyramidal neurons.We compared the wholebrain projection targets of these individual OFC neurons in different cortical layers as well as in the same cortical layer.We found cortical layer-dependent projections characterized by divergent patterns for information delivery.Our study not only provides a structural basis for understanding the principles of laminar organizations in the OFC,but also provides clues for future functional and behavioral studies on OFC pyramidal neurons. | Junjun Wang Pei Sun Xiaohua Lv Sen Jin Anan Li Jianxia Kuang Ning Li Yadong Gang Rui Guo Shaoqun Zeng Fuqiang Xu Yu-Hui Zhang | 2021 | Neuroscience Bulletin2021，37，4： | 5 |
| 2 | Influence of the quickness and duration of De Qi on the analgesic effect of acupuncture in primary dysmenorrhea patients with a cold and dampness stagnation pattern显示文摘OBJECTIVE: To investigate the influence of the quickness and duration of De Qi(or Qi arrival) on the analgesic effect of acupuncture in primary dysmenorrhea patients with a cold and dampness stagnation pattern.METHODS: Sixty-eight patients were randomly assigned to the De Qi group(deep needling with thick needles and manipulation, n = 17) or the non-De Qi group(shallow needling with thin needles and no manipulation, n = 51). Both groups underwent needling at Sanyinjiao(SP 6) for 30 min.The visual analogue scale was used to measure the degree of menstrual pain, and the Acupuncture De Qi Clinical Assessment Scale was used to assess De Qi. Only data from patients who experienced actual De Qi were included in the analysis.RESULTS: Thirty-nine patients experienced actual De Qi. Patients who experienced actual De Qi in the De Qi group(n = 14) felt De Qi more rapidly(P =0.028) and for a longer duration(P = 0.04) than patients who experienced actual De Qi in the non-De Qi group(n = 25). Both groups showed a reduction in the visual analogue scale score for pain after treatment. The analgesic effect did not significantly differ between the two groups. The occurrence time of De Qi showed a significant negative correlation with pain reduction at 20 and 30 min after needle removal(P < 0.05). There was no correlation between the duration of De Qi and the therapeutic effect.CONCLUSION: In primary dysmenorrhea patients with a cold and dampness stagnation pattern,quicker onset of De Qi when needling Sanyinjiao(SP 6) achieves a better analgesic outcome. However, a longer duration of De Qi does not affect the degree of analgesia. Compared with minimal acupuncture, active acupuncture stimulation achieves a more rapid onset and longer duration of De Qi. | Hu Nijuan Ma Liangxiao Wang Pei Wu Guiwen Zhao Minyi Hu Shangqing Sun Junjun Wang Yafeng Zhang Zhuang Zhu Jiang | 2019 | Journal of Traditional Chinese Medicine2019，39，2： | 4 |
| 3 | China's battery electric vehicles lead the world:achievements in technology system architecture and technological breakthroughs显示文摘Developing new energy vehicles has been a worldwide consensus,and developing new energy vehicles characterized by pure electric drive has been China's national strategy.After more than 20 years of high-quality development of China's electric vehicles(EVs),a technological R&D layout of“Three Verticals and Three Horizontals”has been created,and technological advantages have been accumulated.As a result,China's new energy vehicle market has ranked first in the world since 2015.To systematically solve the key problems of battery electric vehicles(BEVs)such as“driving range anxiety,long battery charging time,and driving safety hazards”,China took the lead in putting forward a“system engineering-based technology system architecture for BEVs”and clarifying its connotation.This paper analyzes the research status and progress of the three core components of this architecture,namely,“BEV platform,charging/swapping station,and real-time operation monitoring platform”,and their key technological points.The three major demonstration projects of the 2008 Beijing Olympic Games,the 2022 Beijing Winter Olympics,and the intelligent and connected autonomous battery electric bus project are discussed to specify the applications of BEVs in China.The key research directions for upgrading BEV technologies remain to be further improving the vehicle-level all-climate environmental adaptability and all-day safety of BEVs,systematically solving the charging problem of BEVs and improving their application convenience,and safeguarding safety with early warning and implementing active/passive safety protection for the whole life cycle of power batteries on the basis of BEVs'operation big data.BEVs have acquired new technological features such as intelligent and networked technology empowerment,extensive integration of control-by-wire systems,a platform of chassis hardware,and modularization of functional software. | Hongwen He Fengchun Sun Zhenpo Wang Cheng Lin Chengning Zhang Rui Xiong Junjun Deng Xiaoqing Zhu Peng Xie Shuo Zhang Zhongbao Wei Wanke Cao Li Zhai | 2022 | Green Energy and Intelligent Transportation2022，1，1： | 2 |
| 4 | A three-dimensional two-level gradient smoothing meshfree method for rainfall induced landslide simulations显示文摘A three-dimensional two-level gradient smoothing meshfree method is presented for rainfall induced landslide simulations. The two-level gradient smoothing for meshfree shape function is elaborated in the threedimensional Lagrangian setting with detailed implementation procedure. It is shown that due to the successive gradient smoothing operation without the requirement of derivative computation in the present formulation, the two-level smoothed gradient of meshfree shape function is capable of achieving a given influence domain more efficiently than the standard gradient of meshfree shape function. Subsequently, the two-level smoothed gradient of meshfree shape function is employed to discretize the weak form of coupled rainfall seepage and soil motion equations in a nodal integration format, as provides an efficient three-dimensional regularized meshfree formulation for large deformation rainfall induced landslide simulations. The exponential damage and pressure dependent plasticity relationships are utilized to describe the failure evolution in landslides. The plastic response of soil is characterized by the true effective stress measure, which is updated according to the rotationally neutralized objective integration algorithm. The effectiveness of the present threedimensional two?level gradient smoothing meshfree method is demonstrated through numerical examples. | Dongdong WANG Jiarui WANG Junchao WU Junjun DENG Ming SUN | 2019 | Frontiers of Structural and Civil Engineering2019，13，2： | 2 |

| 6 | The First High-quality Reference Genome of Sika Deer Provides Insights into High-tannin Adaptation显示文摘Sika deer are known to prefer oak leaves,which are rich in tannins and toxic to most mammals;however,the genetic mechanisms underlying their unique ability to adapt to living in the jungle are still unclear.In identifying the mechanism responsible for the tolerance of a highly toxic diet,we have made a major advancement by explaining the genome of sika deer.We generated the first high-quality,chromosome-level genome assembly of sika deer and measured the correlation between tannin intake and RNA expression in 15 tissues through 180 experiments.Comparative genome analyses showed that the UGT and CYP gene families are functionally involved in the adaptation of sika deer to high-tannin food,especially the expansion of the UGT family 2 subfamily B of UGT genes.The first chromosome-level assembly and genetic characterization of the tolerance to a highly toxic diet suggest that the sika deer genome may serve as an essential resource for understanding evolutionary events and tannin adaptation.Our study provides a paradigm of comparative expressive genomics that can be applied to the study of unique biological features in non-model animals. | Xiumei Xing Cheng Ai Tianjiao Wang Yang Li Huitao Liu Pengfei Hu Guiwu Wang Huamiao Liu Hongliang Wang Ranran Zhang Junjun Zheng Xiaobo Wang Lei Wang Yuxiao Chang Qian Qian Jinghua Yu Lixin Tang Shigang Wu Xiujuan Shao Alun Li Peng Cui Wei Zhan Sheng Zhao Zhichao Wu Xiqun Shao Yimeng Dong Min Rong Yihong Tan Xuezhe Cui Shuzhuo Chang Xingchao Song Tongao Yang Limin Sun Yan Ju Pei Zhao Huanhuan Fan Ying Liu Xinhui Wang Wanyun Yang Min Yang Tao Wei Shanshan Song Jiaping Xu Zhigang Yue Qiqi Liang Chunyi Li Jue Ruan Fuhe Yang | 2023 | Genomics, Proteomics & Bioinformatics2023，21，1： | 1 |

| 8 | ACACB is a novel metabolism-related biomarker in the prediction of response to cetuximab therapy in metastatic colorectal cancer显示文摘Cetuximab is one of the most valuable targeted therapy monoclonal antibodies in the treatment of metastatic colorectal cancer(CRC).However,the mechanisms affecting cetuximab resistance in CRC treatment remain unclear.Metabolism,especially fatty acid metabolism,has been reported to play an important role in tumor treatment.The correlation between cetuximab resistance and metabolism and whether it can be a new biomarker to evaluate the sensitivity of cetuximab in CRC treatment still need to be further explored.In this study,we perform a comprehensive analysis to confirm the relationship between fatty acid metabolism and cetuximab resistance,and the differentially expressed genes(DEGs)related to cetuximab drug resistance in CRC are screened by bioinformatics technology.We find that acetyl-CoA carboxylase beta(ACACB),ADH1C,CES1,MGLL,FMO5,and GPT are the hub DEGs,and ACACB is the most important biomarker among them.In addition,we systematically analyze the role of ACACB in the tumorigenesis of CRC,including tissue expression,CRC cell growth,cetuximab sensitivity,and potential downstream pathways,by using bioinformatics techniques,in vitro experiments and clinical cohort validation.Our results confirm that cetuximab resistance is correlated with metabolism.ACACB can lead to decreased sensitivity to cetuximab in CRC,and its mechanism may be related to EGFR phosphorylation,which could affect the activation of the mTOR/Akt signaling pathway and regulation of CDT1-,cyclin D1-,and p21-related cell cycle modulation. | Hi-Ju Hong Yanfei Shao Sen Zhang Guang Yang Hongtao Jia Xiao Yang Ling Huang Shuchun Li Batuer Aikemu Luyang Zhang Junjun Ma Lu Zang Jing Sun Minhua Zheng | 2022 | Acta Biochimica et Biophysica Sinica2022，54，11： | 1 |

The theory of PMA is introduced firstly, and then the iterative renewed manner is improved to resolve the unbalance problem under amplitude and phase control. In order to validate the algorithm correct and effective, an actual engineering application example is investigated. The beam synthesis results of 1.0~4.5 times broadening under the phase only control and the amplitude and phase control using improved PMA are given. The results show that the beam directivity, the beam broadening, and the side-lobe level requirements were met. It is demonstrated that the improved PMA was effective and feasible for SAR application. | Jiao Junjun Sun Huifeng | 2014 | Journal of Electronics(China)2014，31，5： | 0 |

| 11 | Physiological and molecular bases of the boron deficiency response in tomatoes显示文摘Boron is an essential microelement for plant growth.Tomato is one of the most cultivated fruits and vegetables in the world,and boron deficiency severely inhibits its yield and quality.However,the mechanism of tomato in response to boron deficiency remains largely unclear.Here,we investigated the physiological and molecular bases of the boron deficiency response in hydroponically grown tomato seedlings.Boron deficiency repressed the expression of genes associated with nitrogen metabolism,while it induced the expression of genes related to the pentose phosphate pathway,thereby altering carbon flow to provide energy for plants to cope with stress.Boron deficiency increased the accumulation of copper,manganese and iron,thereby maintaining chlorophyll content and photosynthetic efficiency at the early stage of stress.In addition,boron deficiency downregulated the expression of genes involved in cell wall organization and reduced the contents of pectin and cellulose in roots,ultimately retarding root growth.Furthermore,boron deficiency markedly altered phytohormone levels and signaling pathways in roots.The contents of jasmonic acid,jasmonoy1-L-isoleucine,trans-zeatin riboside,abscisic acid,salicylic acid,and SA glucoside were decreased;in contrast,the contents of isopentenyladenine riboside and ethylene precursor 1-aminocyclopropane-1-carboxylic acid were increased in the roots of boron-deficient tomato plants.These results collectively indicate that tomato roots reprogram carbon/nitrogen metabolism,alter cell wall components and modulate phytohormone pathways to survive boron deficiency.This study provides a theoretical basis for further elucidating the adaptive mechanism of tomato in response to boron deficiency. | Junjun Li Huihui Fan Qianqian Song Lili Jing Hao Yu Ruishan Li Ping Zhang Fei Liu Weimin Li Liangliang Sun Jin Xu | 2023 | Horticulture Research2023，10，12： | 0 |
| 12 | Dual Nanofillers-Reinforced Noncovalently Cross-Linked Polymeric Composites with Unprecedented Mechanical Strength显示文摘Noncovalentlycross-linkedpolymermaterials through healing,recycling,and reprocessing can reduce materials consumption and alleviate environmental pollution.However,it remains a huge challenge to fabricate super-strong noncovalently cross-linked polymer materials with mechanical strength comparable to high-performance engineering polymers.Herein,healable and reprocessable noncovalently cross-linked polymer compositeswith an unprecedented mechanical strength are fabricated by complexation of polyacrylic acid(PAA),polyvinylpyrrolidone(PVPON),and carbonized polymer dots(CPDs)(denoted as PAA-PVPON-CPDs).The incorporation of 15 wt%CPDs generates PAA-PVPON-CPDs compositeswith a tensile strength of∼158 MPa and Young’s modulus of∼8.2GPa.Servingas nanofillers,theCPDs can establish strong interactions with polymers in PAA-PVPON composites.The CPDs and the in situ-formed PAAPVPON nanoparticles work in concert to significantly strengthen the PAA-PVPON-CPDs composites to an unprecedented strength.The PAA-PVPON-CPDs composites exhibit excellent impact resistance and damage tolerance because of the high mechanical strength of the composites and the energy dissipation mechanism of the CPDs and PAA-PVPON nanoparticles.Moreover,the fractured PAA-PVPON-CPDs composites can be healed to restore their original mechanical strength. | Ni An Youliang Zhu Xiaohan Wang Yixuan Li Junjun Liu Xu Fang Zhongyuan Lu Bai Yang Junqi Sun | 2023 | CCS Chemistry2023，5，10： | 0 |
| 13 | Genotypic variance in 13C-photosynthate partitioning and within-plant boll distribution in cotton显示文摘Background:Photosynthate partitioning and within-plant boll distribution play an important role in yield formation of cotton;however,if and how they interact to mediate yield remains unclear.The objective of this study was to investigate the genotypic variance in photosynthate partitioning and within-plant boll distribution,with a focus on their interactions with regard to yield and yield components.A field experiment was conducted in the Yellow River region in China in 2017 and 2018 using a randomized complete block design with three replicates.Photosynthate partitioning of three commercial cultivars(DP 99 B,Lumianyan 21 and Jimian 169),varying in yield potential,to different organs(including bolls)at early flowering,peak flowering,and peak boll-setting stages,as well as withinplant boll distribution at harvest,and their effects on yield formation were examined.Results:Lint yield of Jimian 169 was the highest,followed by Lumianyan 21 and DP 99 B.Similar differences were observed in the number of inner bolls and boll weight among the three cultivars.J169 partitioned significantly more photosynthate to the fruit and fiber than Lumianyan 21 and DP 99 B and allocated over 80%of assimilates to the inner bolls.Additionally,Lumianyan 21 allocated a higher proportion of photosynthate to bolls and fiber,with12.5%–17.6%more assimilates observed in the inner bolls,than DP 99 B.Conclusions:Genotypic variance in lint yield can be attributed to differences in the number of inner bolls and boll weight,which are affected by photosynthate partitioning.Therefore,the partitioning of photosynthate to fiber and inner bolls can be used as an important reference for cotton breeding and cultivation. | NIE Junjun QIN Dulin MAO Lili LIU Yanhui DONG Hezhong SONG Xianliang SUN Xuezhen | 2020 | Journal of Cotton Research2020，3，2： | 0 |
| 14 | Plasma transport simulation under different conditions and optimization analysis of dual-stage grid ion thruster显示文摘In order to study the extraction and acceleration mechanism of the dual-stage grid,a three-dimensional model based on the Particle-In-Cell/Monte Carlo Collision(PIC/MCC)method is performed.Dual-stage grid ion thruster is a new type of electrostatic ion thruster,which can break through the limitations of traditional gridded ion thrusters,and greatly improve the specific impulse.The high performance also makes the grid sensitive to operating parameters.In this paper,the influence of grid parameters on xenon ion thruster’s performance in a wide range is systematically simulated,and the optimal operating condition is given.Both the over-focusing of the plume,and the transparency of the screen grid are improved,and the grid corrosion is reduced through simulation optimization.The specific impulse under the given working conditions is 9877.24 s and the thrust is 7.28 mN.Based on the simulation optimization,the limitation of the dual-stage grid is discussed.The grid performs well under high voltage conditions(>3000 V)but not well under low voltage conditions(<2000 V).Finally,since argon is cheaper and more advantageous in future engineering applications,the plasma distribution and grid extraction ability under xenon and argon are analyzed and compared to study the flexibility of the dual-stage grid ion thruster.The simulation results show that a set of optimal parameters is only applicable to the corresponding propellant,which needs to be optimized for different propellant types. | Yajie HAN Guangqing XIA Bin SUN Chang LU Junjun ZHANG Vladimir A.SAETCHNIKOV | 2023 | Chinese Journal of Aeronautics2023，36，7： | 0 |

| 16 | Path guided motion synthesis for Drosophila larvae显示文摘The deformability and high degree of freedom of mollusks bring challenges in mathematical modeling and synthesis of motions.Traditional analytical and statistical models are limited by either rigid skeleton assumptions or model capacity,and have difficulty in generating realistic and multi-pattern mollusk motions.In this work,we present a large-scale dynamic pose dataset of Drosophila larvae and propose a motion synthesis model named Path2Pose to generate a pose sequence given the initial poses and the subsequent guiding path.The Path2Pose model is further used to synthesize long pose sequences of various motion patterns through a recursive generation method.Evaluation analysis results demonstrate that our novel model synthesizes highly realistic mollusk motions and achieves state-of-the-art performance.Our work proves high performance of deep neural networks for mollusk motion synthesis and the feasibility of long pose sequence synthesis based on the customized body shape and guiding path. | Junjun CHEN Yijun WANG Yixuan SUN Yifei YU Zi’ao LIU Zhefeng GONG Nenggan ZHENG | 2023 | Frontiers of Information Technology & Electronic Engineering2023，24，10： | 0 |
| 17 | An Efficient Webpage Classification Algorithm Based on LSH显示文摘With the explosive growth of Internet information, it is more and more important to fetch real-time and related information. And it puts forward higher requirement on the speed of webpage classification which is one of common methods to retrieve and manage information. To get a more efficient classifier, this paper proposes a webpage classification method based on locality sensitive hash function. In which, three innovative modules including building feature dictionary, mapping feature vectors to fingerprints using Localitysensitive hashing, and extending webpage features are contained. The compare results show that the proposed algorithm has better performance in lower time than the naive bayes one. | Junjun Liu Haichun Sun Zhijun Ding | 2015 | 国际计算机前沿大会会议论文集2015，，1： | 0 |
| 18 | Arabidopsis RNA polymerase Ⅱ C-terminal domain phosphatase-like 1 targets mitogen-activated protein kinase cascades to suppress plant immunity显示文摘Mitogen-activated protein kinase(MAPK) cascades play pivotal roles in plant defense against phytopathogens downstream of immune receptor complexes. The amplitude and duration of MAPK activation must be strictly controlled, but the underlying mechanism remains unclear. Here, we identified Arabidopsis CPL1(C-terminal domain phosphatase-like 1)as a negative regulator of microbe-associated molecular pattern(MAMP)-triggered immunity via a forward-genetic screen. Disruption of CPL1 significantly enhanced plant resistance to Pseudomonas pathogens induced by the bacterial peptide fg22. Furthermore, fg22-induced MPK3/MPK4/MPK6 phosphorylation was dramatically elevated in cpl1 mutants but severely impaired in CPL1 overexpression lines, suggesting that CPL1 might interfere with fg22-induced MAPK activation. Indeed, CPL1 directly interacted with MPK3 and MPK6, as well as the upstream MKK4 and MKK5. A firefy luciferase-based complementation assay indicated that the interaction between MKK4/MKK5 and MPK3/MPK6 was significantly reduced in the presence of CPL1. These results suggest that CPL1 plays a novel regulatory role in suppressing MAMP-induced MAPK cascade activation and MAMP-triggered immunity to bacterial pathogens. | Junjun Wei Wei Sun Xinhang Zheng Shanshan Qiu Shuangyu Jiao Kevin Babilonia Hisashi Koiwa Ping He Libo Shan Wenxian Sun Fuhao Cui | 2023 | Journal of Integrative Plant Biology2023，65，10： | 0 |
| 19 | Fluoride removal from secondary effluent of the graphite industry using electrodialysis:Optimization with response surface methodology显示文摘Response surface methodology was utilized to model and optimize the operational variables for defluoridation using an electrodialysis process as the treatment of secondary effluent of the graphite industry. Experiments were conducted using a Box-Behnken surface statistical design in order to evaluate the effects and the interaction of the influential variables including the operational voltage, initial fluoride concentration and flow rate. The regression models for defluoridation and energy consumption responses were statistically validated using analysis of variance (ANOVA);high coefficient of determination values (R^2 = 0.9772 and R^2 = 0.9814;respectively) were obtained. The quadratic model exhibited high reproducibility and a good fit of the experimental data. The optimum values of the initial fluoride concentration, voltage and flow rate were found to be 13.9 mg/L, 13.4 V, 102.5 L/h, respectively. A fluoride removal efficiency of 99.69% was observed under optimum conditions for the treatment of the secondary effluent of the graphite industry. | Xiaomeng Wang Ning Li Jianye Li Junjun Feng Zhun Ma Yuting Xu Yongchao Sun Dongmei Xu Jian Wang Xueli Gao Jun Gao | 2019 | Frontiers of Environmental Science & Engineering2019，13，4： | 0 |
| 20 | Enhancing Green Ammonia Electrosynthesis Through Tuning Sn Vacancies in Sn‑Based MXene/ MAX Hybrids显示文摘Renewable energy driven N_(2) electroreduction with air as nitrogen source holds great promise for realizing scalable green ammonia production.However,relevant out-lab research is still in its infancy.Herein,a novel Sn-based MXene/MAX hybrid with abundant Sn vacancies,Sn@Ti_(2)CTX/Ti_(2)SnC–V,was synthesized by controlled etching Sn@Ti_(2)SnC MAX phase and demonstrated as an efficient electrocatalyst for electrocatalytic N2 reduction.Due to the synergistic effect of MXene/MAX heterostructure,the existence of Sn vacancies and the highly dispersed Sn active sites,the obtained Sn@Ti2CTX/Ti_(2)SnC–V exhibits an optimal NH_(3) yield of 28.4μg h^(−1) mg_(cat)^(−1) with an excellent FE of 15.57% at−0.4 V versus reversible hydrogen electrode in 0.1 M Na_(2)SO_(4),as well as an ultra-long durability.Noticeably,this catalyst represents a satisfactory NH3 yield rate of 10.53μg h^(−1) mg^(−1) in the home-made simulation device,where commercial electrochemical photovoltaic cell was employed as power source,air and ultrapure water as feed stock.The as-proposed strategy represents great potential toward ammonia production in terms of financial cost according to the systematic technical economic analysis.This work is of significance for large-scale green ammonia production. | Xinyu Dai Zhen‑Yi Du Ying Sun Ping Chen Xiaoguang Duan Junjun Zhang Hui Li Yang Fu Baohua Jia Lei Zhang Wenhui Fang Jieshan Qiu Tianyi Ma | 2024 | Nano-Micro Letters2024，16，5： | 0 |
