| 1 | Inverted polymer solar cells with a solution-processed zinc oxide thin film as an electron collection layer显示文摘A solution-processed zinc oxide (ZnO) thin film as an electron collection layer for polymer solar cells (PSCs) with an inverted device structure was investigated. Power conversion efficiencies (PCEs) of PSCs made with a blend of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61-butyric acid methyl ester (PCBM) are 3.50% and 1.21% for PSCs with and without the ZnO thin film, respectively. Light intensity dependence of the photocurrent and the capacitance-voltage measurement demonstrate that the increased PCEs are due to the restriction of the strong bimolecular recombination in the interface when a thin ZnO layer is inserted between the polymer active layer and the ITO electrode. These results demonstrate that the ZnO thin film plays an important role in the performance of PSCs with an inverted device structure. | YANG TingBin QIN DongHuan LAN LinFeng HUANG WenBo GONG Xiong PENG JunBiao CAO Yong | 2012 | Science China Chemistry2012，55，5： | 10 |
| 2 | Biomaterial-based strategies for maxillofacial tumour therapy and bone defect regeneration显示文摘Issues caused by maxillofacial tumours involve not only dealing with tumours but also repairing jaw bone defects.In traditional tumour therapy,the systemic toxicity of chemotherapeutic drugs,invasive surgical resection,intractable tumour recurrence,and metastasis are major threats to the patients’lives in the clinic.Fortunately,biomaterial-based intervention can improve the efficiency of tumour treatment and decrease the possibility of recurrence and metastasis,suggesting new promising antitumour therapies.In addition,maxillofacial bone tissue defects caused by tumours and their treatment can negatively affect the physiological and psychological health of patients,and investment in treatment can result in a multitude of burdens to society.Biomaterials are promising options because they have good biocompatibility and bioactive properties for stimulation of bone regeneration.More interestingly,an integrated material regimen that combines tumour therapy with bone repair is a promising treatment option.Herein,we summarized traditional and biomaterial-mediated maxillofacial tumour treatments and analysed biomaterials for bone defect repair.Furthermore,we proposed a promising and superior design of dual-functional biomaterials for simultaneous tumour therapy and bone regeneration to provide a new strategy for managing maxillofacial tumours and improve the quality of life of patients in the future. | Bowen Tan Quan Tang Yongjin Zhong Yali Wei Linfeng He Yanting Wu Jiabao Wu Jinfeng Liao | 2021 | International Journal of Oral Science2021，13，1： | 9 |
| 3 | Design,modeling and experiments of broadband tristable galloping piezoelectric energy harvester显示文摘Galloping based piezoelectric energy harvester is a kind of micro-environmental energy harvesting device based on flowinduced vibrations.A novel tristable galloping-based piezoelectric energy harvester is constructed by introducing a nonlinear magnetic force on the traditional galloping-based piezoelectric energy harvester.Based on Euler-Bernoulli beam theory and Kirchhoff’s law,the corresponding aero-electromechanical model is proposed and validated by a series of wind tunnel experiments.The parametric study is performed to analyse the response of the tristable galloping-based piezoelectric energy harvester.Numerical results show that comparing with the galloping-based piezoelectric energy harvester,the mechanism of the tristable galloping-based piezoelectric energy harvester is more complex.With the increase of a wind speed,the vibration of the bluff body passes through three branches:intra-well oscillations,chaotic oscillations,and inter-well oscillations.The threshold wind speed of the presented harvester for efficiently harvesting energy is 1.0 m/s,which is decreased by 33% compared with the galloping-based piezoelectric energy harvester.The maximum output power of the presented harvester is 0.73 mW at 7.0 m/s wind speed,which is increased by 35.3%.Compared with the traditional galloping-based piezoelectric energy harvester,the presented tristable galloping-based piezoelectric energy harvester has a better energy harvesting performance from flow-induced vibrations. | Junlei Wang Linfeng Geng Shengxi Zhou Zhien Zhang Zhihui Lai Daniil Yurchenko | 2020 | Acta Mechanica Sinica2020，36，3： | 9 |
| 4 | Radiofrequency ablation combined with transcatheter arterial chemoembolization therapy versus surgical resection for Barcelona-Clinic Liver Cancer(BCLC) A hepatocellular carcinoma: a meta-analysis显示文摘Purpose: The objective of our study was to compare the effectiveness of the combination of transcatheter arterial chemoembolization(TACE) and radiofrequency ablation(RFA) with that of surgical resection(SR) in Barcelona-Clinic Liver Cancer(BCLC) A hepatocellular carcinoma. Materials and Methods: PubMed, Medline, Embase, and Cochrane Library were searched for comparisons of the two therapies from January 2006 to December 2017. Overall survival rate(OS), recurrence-free survival rate(RFS), complications, and the average length of hospital stay were compared and analyzed. Review Manager v. 5.2 from the Cochrane Collaboration was used for statistical analyses. Results: Seven case-control studies and one randomized controlled trial were identified, of which 717 were treated with a combination of TACE and RFA and 785 were treated with SR. Meta-analysis data revealed that TACE plus RFA had significantly better effectiveness on 1.0-y OS(OR = 0.50, p =.009). The major complications(ORcomplications = 1.88, p =.02) after the combined therapy were significantly lower than those after SR. There were three studies that reported the average length of hospital stay. The hospital stay for the SR group vs the combined therapy group was 19.8 ± 8.4 d vs 7.4 ± 2.2 d, respectively(p <.0001); 18.7 ± 4.9 d vs 11.5 ± 6.9 d, respectively(p <.0001); and 16.6 ± 6.7 d vs 8.5 ± 4.1 d, respectively(p <.0001). There was no significant difference in 3.0-or 5.0-y OS and 1.0-, 3.0-, or 5.0-y RFS. Conclusion: The combination of TACE and RFA has advantages in improving 1.0-y OS, reducing complications, and shortening the length of hospital stay over that of SR in the treatment of patients with BCLC A HCC. | Weidong Wang Sinan Hou Zelong Zhong JiaYan Ni Xiongying Jiang Dong Chen Yaoting Chen Jianghong Luo Hongliang Sun Linfeng Xu | 2018 | Journal of Interventional Medicine2018，1，1： | 9 |
| 5 | SwinFusion: Cross-domain Long-range Learning for General Image Fusion via Swin Transformer显示文摘This study proposes a novel general image fusion framework based on cross-domain long-range learning and Swin Transformer,termed as SwinFusion.On the one hand,an attention-guided cross-domain module is devised to achieve sufficient integration of complementary information and global interaction.More specifically,the proposed method involves an intra-domain fusion unit based on self-attention and an interdomain fusion unit based on cross-attention,which mine and integrate long dependencies within the same domain and across domains.Through long-range dependency modeling,the network is able to fully implement domain-specific information extraction and cross-domain complementary information integration as well as maintaining the appropriate apparent intensity from a global perspective.In particular,we introduce the shifted windows mechanism into the self-attention and cross-attention,which allows our model to receive images with arbitrary sizes.On the other hand,the multi-scene image fusion problems are generalized to a unified framework with structure maintenance,detail preservation,and proper intensity control.Moreover,an elaborate loss function,consisting of SSIM loss,texture loss,and intensity loss,drives the network to preserve abundant texture details and structural information,as well as presenting optimal apparent intensity.Extensive experiments on both multi-modal image fusion and digital photography image fusion demonstrate the superiority of our SwinFusion compared to the state-of-theart unified image fusion algorithms and task-specific alternatives.Implementation code and pre-trained weights can be accessed at http://gffzz188fe103f8f1460aswwfkxpkvw9n060nk.ffgz.tsg.suse.edu.cn/Linfeng-Tang/SwinFusion. | Jiayi Ma Linfeng Tang Fan Fan Jun Huang Xiaoguang Mei Yong Ma | 2022 | IEEE/CAA Journal of Automatica Sinica2022，9，7： | 8 |
| 6 | Differentiation potential of bone marrow mesenchymal stem cells in duck显示文摘The bone marrow mesenchymal stem cells(MSCs) are multipotent stem cells which can differentiate into mesenchymal cells in vitro.In this study,MSCs in duck were isolated from bone marrow by density gradient centrifuge separation,purified and expanded in the me-dium.The primary MSCs were expanded for 11 passages.The different-passage MSCs were induced to differentiate into osteoblasts and neuron-like cells.Karyotype analysis indicated that MSCs kept diploid condition and the hereditary feature was stable.The different-passage MSCs expressed CD44,ICAM-1 and SSEA-4,but not CD34,CD45 and SSEA-1 when detected by immunofluorescence staining.There was no significant difference among the positive rates of passages 2,6 and 8(P > 0.05),but a significant difference existed among those of passages 2,6,8 and 11(P < 0.05).After the osteogenic inducement was added,the induced different-passage MSCs expressed high-level alkaline phosphatase(ALP),and are positive for tetracycline staining,Alizarin Red staining and Von Kossa staining.After the neural inducement was added,about 70% cells exhibited typical neuron-like phenotype,the induced different-passage MSCs expressed Nestin,neuron-specific enolase(NSE) and glial fibrillary acidic protein(GFAP) when detected by immunofluorescence staining.There was no significant difference among the positive rates of passages 3,4 and 6(P>0.05),but a significant difference existed among those of passages 3,4,6 and 8(P<0.05).These results suggest that MSCs in duck were capable of differentiating into osteoblasts and neuron-like cells in vitro. | Linfeng Li Xiujuan Bai Xuelian Gong Hongkun Liu Lina Chen Weijun Guan Yuehui Ma | 2009 | Journal of Genetics and Genomics2009，36，3： | 8 |
| 7 | Simulation model of self-organizing pedestrian movement considering following behavior显示文摘在本文中一种新的力学模型被引入到社会力模型中,用来仿真相向行人流中的跟随行为。这种跟随行为指的是行人通过接近同向行人以避免与反向行人冲突的行为。新的力学模型类似于一种引力模型,在建模过程中考虑了行人的视野范围、自身的运动状态、被跟随行人的运动状态等因素。我们利用新的力学模型对相向行人流进行了仿真,研究了跟随行为对渠化现象、行人间冲突以及双向通道通行效率的影响。仿真结果表明:跟随行为能促进渠化现象形成,并能起到缓解相向行人流拥堵的作用;跟随行为具有降低相向行人流冲突次数的作用,这种作用在入口流量较低时并不明显,但随着行人流量的升高而增强。跟随行为能够提高双向通道的通行效率,并且跟随行为的强度参数越大通道的通行效率越高。 | Zhilu YUAN Hongfei JIA Mingjun LIAO Linfeng ZHANG Yixiong FENG Guangdong TIAN | 2017 | Frontiers of Information Technology & Electronic Engineering2017，18，8： | 7 |

| 10 | Insights into triterpene synthesis and unsaturated fatty-acid accumulation provided by chromosomallevel genome analysis of Akebia trifoliata subsp . australis显示文摘Akebia trifoliata subsp.australis is a well-known medicinal and potential woody oil plant in China.The limited genetic information available for A.trifoliata subsp.australis has hindered its exploitation.Here,a high-quality chromosomelevel genome sequence of A.trifoliata subsp.australis is reported.The de novo genome assembly of 682.14 Mb was generated with a scaffold N50 of 43.11 Mb.The genome includes 25,598 protein-coding genes,and 71.18%(485.55 Mb)of the assembled sequences were identi fi ed as repetitive sequences.An ongoing massive burst of long terminal repeat(LTR)insertions,which occurred~1.0 million years ago,has contributed a large proportion of LTRs in the genome of A.trifoliata subsp.australis.Phylogenetic analysis shows that A.trifoliata subsp.australis is closely related to Aquilegia coerulea and forms a clade with Papaver somniferum and Nelumbo nucifera,which supports the well-established hypothesis of a close relationship between basal eudicot species.The expansion of UDP-glucoronosyl and UDP-glucosyl transferase gene families and fi-amyrin synthase-like genes and the exclusive contraction of terpene synthase gene families may be responsible for the abundant oleanane-type triterpenoids in A.trifoliata subsp.australis.Furthermore,the acyl-ACP desaturase gene family,including 12 stearoyl-acyl-carrier protein desaturase(SAD)genes,has expanded exclusively.A combined transcriptome and fatty-acid analysis of seeds at fi ve developmental stages revealed that homologs of SADs,acyl-lipid desaturase omega fatty acid desaturases(FADs),and oleosins were highly expressed,consistent with the rapid increase in the content of fatty acids,especially unsaturated fatty acids.The genomic sequences of A.trifoliata subsp.australis will be a valuable resource for comparative genomic analyses and molecular breeding. | Hui Huang Juan Liang Qi Tan Linfeng Ou Xiaolin Li Caihong Zhong Huilin Huang Ian Max Moller Xianjin Wu Songquan Song | 2021 | Horticulture Research2021，8，1： | 5 |

| 12 | Flexoelectric materials and their related applications: A focused review显示文摘Flexoelectricity refers to the mechanical-electro coupling between strain gradient and electric polarization, and conversely, the electro-mechanical coupling between electric field gradient and mechanical stress. This unique effect shows a promising size effect which is usually large as the material dimension is shrunk down. Moreover, it could break the limitation of centrosymmetry, and has been found in numerous kinds of materials which cover insulators, liquid crystals, biological materials, and semiconductors. In this review, we will give a brief report about the recent discoveries in flexoelectricity, focusing on the flexoelectric materials and their applications. The theoretical developments in this field are also addressed. In the end, the perspective of flexoelectricity and some open questions which still remain unsolved are commented upon. | Longlong SHU Renhong LIANG Zhenggang RAO Linfeng FEI Shanming KE Yu WANG | 2019 | Journal of Advanced Ceramics2019，8，2： | 4 |
| 13 | Very-High Color Rendering Index Hybrid White Organic Light-Emitting Diodes with Double Emitting Nanolayers显示文摘A very-high color rendering index white organic light-emitting diode(WOLED) based on a simple structure was successfully fabricated. The optimized device exhibits a maximum total efficiency of 13.1 and 5.4 lm/W at 1,000 cd/m2. A peak color rendering index of 90 and a relatively stable color during a wide range of luminance were obtained. In addition, it was demonstrated that the 4,40,400-tri(9-carbazoyl) triphenylamine host influenced strongly the performance of this WOLED.These results may be beneficial to the design of both material and device architecture for high-performance WOLED. | Baiquan Liu Miao Xu Lei Wang Hong Tao Yueju Su Dongyu Gao Linfeng Lan Jianhua Zou Junbiao Peng | 2014 | Nano-Micro Letters2014，6，4： | 4 |
| 14 | Oxidative depolymerization of lignin improved by enzymolysis pretreatment with laccase显示文摘A new lignin depolymerization approach for improving the yield of aromatic monomers(YAM) by enzymolysis pretreatment was investigated, in which lignin was pretreated with laccase followed by oxidative depolymerization. It was found that lignin depolymeirzation was enhanced significantly by enzymolysis. The oxidative depolymerization contributed to 21.37% of YAM after the enzymolysis pretreatment,whereas the conventional oxidative depolymerization only gave 14.10% of YAM. The addition of ethanol in enzymatic pretreatment process improved the efficiency of enzymolysis, which effectively improved the solubility of pretreated lignin and depolymerization degree(DD) of lignin. The enzymolysis pretreatment increased the content of syringyl(S) style aromatic monomers, which hindered the recondensation among polymerized products. As lignin has low solubility in acidic aqueous solution, ethanol was added into enzymolysis system to improve the efficiency. However, the enzymolysis of lignin should be carried out for a limited period of time to prevent the inactivation of laccase. | Yuan Zhu Xinping Ouyang Ying Zhao Linfeng Jiang Haijun Guo Xueqing Qiu | 2018 | Journal of Energy Chemistry2018，27，3： | 4 |
| 15 | Vertical variations and associated ecological function of bacterial communities from Sphagnum to underlying sediments in Dajiuhu Peatland显示文摘To investigate vertical changes of bacterial communities from living plants to the associated sediments and bacterial biogeochemical roles in peatland ecosystem,samples of different part of individual Sphagnum palustre and the different layers of the underlying sediments were collected from Dajiuhu Peatland in central China.All samples were subject to 16S rRNA gene clone libraries and quantitative PCR analysis.Even though bacteria vary in abundance at the same order of magnitude in all samples,they show great profile difference in composition from the top part of S.palustre to the low layer of the sediments.Cyanobacteria and alpha-Proteobacteria dominate at the top part whereas Acidobacteria at the middle part of S.palustre.Alpha-Proteobacteria and Acidobacteria are the dominant phyla at the bottom part of S.palustre and in the surface peat sediment.In contrast,bacterial communities in the subsurface sediments are dominated by Acidobacteria.These profile distributions of different bacterial communities are closely related to their ecological functions in the peatland ecosystem.Specifically,most Cyanobacteria were observed at the top green part of S.palustre,a horizon where the active photosynthesis of the moss occurs,which infers their endosymbiosis.In contrast,Acidobacteria,dominant in the subsurface sediments,are able to decompose the specific compounds on the cell wall of Sphagnum moss and thus might play an important role in the formation of the peatland,including the acidic condition.Methane oxidizing process might have been underestimated in Sphagnum peatland due to the identification of Methylocystaceae in all parts of the moss investigated here.The vertical difference in bacterial composition and bacterial ecological functions presented here sheds light on the understanding of biogeochemical processes,in particular the CH4 flux,in peat ecosystems. | XIANG Xing WANG HongMei GONG LinFeng LIU Qiao | 2014 | Science China Earth Sciences2014，57，5： | 4 |
| 16 | Trajectory prediction of ballistic missiles using Gaussian process error model显示文摘Ballistic Missile Trajectory Prediction(BMTP)is critical to air defense systems.Most Trajectory Prediction(TP)methods focus on the coast and reentry phases,in which the Ballistic Missile(BM)trajectories are modeled as ellipses or the state components are propagated by the dynamic integral equations on time scales.In contrast,the boost-phase TP is more challenging because there are many unknown forces acting on the BM in this phase.To tackle this difficult problem,a novel BMTP method by using Gaussian Processes(GPs)is proposed in this paper.In particular,the GP is employed to train the prediction error model of the boost-phase trajectory database,in which the error refers to the difference between the true BM state at the prediction moment and the integral extrapolation of the BM state.And the final BMTP is a combination of the dynamic equation based numerical integration and the GP-based prediction error.Since the trained GP aims to capture the relationship between the numerical integration and the unknown error,the modified BM state prediction is closer to the true one compared with the original TP.Furthermore,the GP is able to output the uncertainty information of the TP,which is of great significance for determining the warning range centered on the predicted BM state.Simulation results show that the proposed method effectively improves the BMTP accuracy during the boost phase and provides reliable uncertainty estimation boundaries. | Ruiping JI Yan LIANG Linfeng XU Zhenwei WEI | 2022 | Chinese Journal of Aeronautics2022，35，1： | 3 |
| 17 | The clock system for LHAASO WCDA based on reduced White Rabbit显示文摘Due to the large scale of Water Cherenkov Detector Array in Large High Altitude Air Shower Observatory, the frontend digitization is imperative.Thus a clock distribution system is desired,which broadcasts the synchronous clock signals with low jitter to the frontend electronics distributed in the field of 90 000 m^2.The White Rabbit protocol provides an option,which has been approved to achieve sub-ns accuracy and ps jitter in the synchronization of around 1 000 nodes in the order of 10 km.But the hierarchy of the original is too complex for Large High Altitude Air Shower Observatory application.Thus we proposed a reduced scheme based on the White Rabbit protocol.The validation circuit shows that the clock skew due to the fiber length difference can be adjusted to less than 25 ps and the clock jitter is less than 62 ps. | LI Cheng LIU Shubin SHANG Linfeng CAO Ping AN Qi | 2012 | Nuclear Science and Techniques2012，23，4： | 3 |
| 18 | Combining WV-2 images and tree physiological factors to detect damage stages of Populus gansuensis by Asian longhorned beetle (Anoplophora glabripennis) at the tree level显示文摘Background:Anoplophora glabripennis(Motschulsky),commonly known as Asian longhorned beetle(ALB),is a wood-boring insect that can cause lethal infestation to multiple borer leaf trees.In Gansu Province,northwest China,ALB has caused a large number of deaths of a local tree species Populus gansuensis.The damaged area belongs to Gobi desert where every single tree is artificially planted and is extremely difficult to cultivate.Therefore,the monitoring of the ALB infestation at the individual tree level in the landscape is necessary.Moreover,the determination of an abnormal phenotype that can be obtained directly from remote-sensing images to predict the damage degree can greatly reduce the cost of field investigation and management.Methods:Multispectral WorldView-2(WV-2)images and 5 tree physiological factors were collected as experimental materials.One-way ANOVA of the tree’s physiological factors helped in determining the phenotype to predict damage degrees.The original bands of WV-2 and derived vegetation indices were used as reference data to construct the dataset of a prediction model.Variance inflation factor and stepwise regression analyses were used to eliminate collinearity and redundancy.Finally,three machine learning algorithms,i.e.,Random Forest(RF),Support Vector Machine(SVM),Classification And Regression Tree(CART),were applied and compared to find the best classifier for predicting the damage stage of individual P.gansuensis.Results:The confusion matrix of RF achieved the highest overall classification accuracy(86.2%)and the highest Kappa index value(0.804),indicating the potential of using WV-2 imaging to accurately detect damage stages of individual trees.In addition,the canopy color was found to be positively correlated with P.gansuensis’damage stages.Conclusions:A novel method was developed by combining WV-2 and tree physiological index for semi-automatic classification of three damage stages of P.gansuensis infested with ALB.The canopy color was determined as an abnormal phenotype that could be directly assessed using remote-sensing images at the tree level to predict the damage degree.These tools are highly applicable for driving quick and effective measures to reduce damage to pure poplar forests in Gansu Province,China. | Quan Zhou Xudong Zhang Linfeng Yu Lili Ren Youqing Luo | 2021 | Forest Ecosystems2021，8，3： | 3 |

| 20 | FeCo alloy catalysts promoting polysulfide conversion for advanced lithium-sulfur batteries显示文摘Lithium sulfur batteries(LSBs)draw extensive interest because of the ultra-high capacity and low material cost.However,the sluggish lithium polysulfides(LIPSs)conversion processes are detrimental to cycle stability and rate capability,inhibiting the commercial application of LSBs.Here we present the well-designed Fe Co alloy catalysts anchored on porous carbon(FeCo-C)as sulfur host to improve the electrochemical performance by accelerating the conversion reactions.The FeCo alloy demonstrates high catalytic effect and strong adsorption capability of LIPSs,in which potential polarization can be greatly decreased and'shuttle effects'can be largely avoided.As a result,the obtained S/Fe Co-C composites show an initial specific capacity of 791.9 m Ah g^-1 at a large current density of 2 C and maintain 502.5 mAh g^-1 even after 500 cycles.Moreover,720 m Ah g^-1(corresponding to 70%retention)can be achieved after 100 cycles at 0.2 C with a high sulfur content of 80 wt%,enabling high sulfur utilization.This work not only provides a new insight to investigate the conversion kinetics of Li PSs,but also opens up a new avenue for advanced lithium sulfur batteries. | Hongyi Li Linfeng Fei Rong Zhang Shenglan Yu Yongyi Zhang Longlong Shu Yong Li Yu Wang | 2020 | Journal of Energy Chemistry2020，29，10： | 3 |
