| 1 | Blown sand motion within the sand-control system in the southern section of the Taklimakan Desert Highway显示文摘Although scientists have performed many studies in the Taklimakan Desert, few of them have reported the blown sand motion along the southern edge of the Taklimakan Desert Highway, which differs significantly from the northern region in terms of aeolian sand geomorphology and formation environment. Based on the field observation data of airflow and aeolian sand transport, continuous monitoring data of erosional and depositional processes between 14 April 2009 and 9 April 2011 and data of surface sand grains from the classical section along the southern edge of the Taklimakan Desert Highway, this paper reported the blown sand motion within the sand-control system of the highway. The main results are as follows: 1) The existing sand-control system is highly effective in preventing and controlling desertification. Wind velocities within the sand-control system were approximately 33%–100% of those for the same height above the mobile sand surface. Aeolian sand fluxes were approximately 0–31.21% of those of the mobile sand surface. Sand grains inside the system, with a mean diameter of 2.89 φ, were finer than those(2.15 φ) outside the system. In addition, wind velocities basically followed a logarithmic law, but the airflow along the classical section was mainly determined by topography and vegetation. 2) There were obvious erosional and depositional phenomena above the surface within the sand-control system, and these phenomena have very consistent patterns for all observation points in the two observed years. The total thicknesses of erosion and deposition ranged from 0.30 to 14.60 cm, with a mean value of 3.67 cm. In contrast, the deposition thicknesses were 1.90–22.10 cm, with a mean value of 7.59 cm, and the erosion thicknesses were 3.51–15.10 cm, with a mean value of 8.75 cm. The results will aid our understanding of blown sand within the sand-control system and provide a strong foundation for optimizing the sand-control system. | CHENG Hong HE Jiajia XU Xingri ZOU Xueyong WU Yongqiu LIU Chenchen DONG Yifan PAN Meihui WANG Yanzai ZHANG Hongyan | 2015 | Journal of Arid Land2015，7，5： | 8 |
| 2 | Vertically Aligned Silicon Carbide Nanowires/Boron Nitride Cellulose Aerogel Networks Enhanced Thermal Conductivity and Electromagnetic Absorbing of Epoxy Composites显示文摘With the innovation of microelectronics technology, the heat dissipation problem inside the device will face a severe test. In this work, cellulose aerogel(CA) with highly enhanced thermal conductivity(TC) in vertical planes was successfully obtained by constructing a vertically aligned silicon carbide nanowires(SiC NWs)/boron nitride(BN) network via the ice template-assisted strategy. The unique network structure of SiC NWs connected to BN ensures that the TC of the composite in the vertical direction reaches 2.21 W m^(-1) K^(-1) at a low hybrid filler loading of 16.69 wt%, which was increased by 890% compared to pure epoxy(EP). In addition, relying on unique porous network structure of CA, EP-based composite also showed higher TC than other comparative samples in the horizontal direction. Meanwhile, the composite exhibits good electrically insulating with a volume electrical resistivity about 2.35 × 10^(11) Ω cm and displays excellent electromagnetic wave absorption performance with a minimum reflection loss of-21.5 dB and a wide effective absorption bandwidth(<-10 dB) from 8.8 to 11.6 GHz. Therefore, this work provides a new strategy for manufacturing polymer-based composites with excellent multifunctional performances in microelectronic packaging applications. | Duo Pan Gui Yang Hala MAbo-Dief Jingwen Dong Fengmei Su Chuntai Liu Yifan Li Ben Bin Xu Vignesh Murugadoss Nithesh Naik Salah MEl-Bahy Zeinhom MEl-Bahy Minan Huang Zhanhu Guo | 2022 | Nano-Micro Letters2022，14，7： | 7 |
| 3 | Transformers in computational visual media:A survey显示文摘Transformers,the dominant architecture for natural language processing,have also recently attracted much attention from computational visual media researchers due to their capacity for long-range representation and high performance.Transformers are sequence-to-sequence models,which use a selfattention mechanism rather than the RNN sequential structure.Thus,such models can be trained in parallel and can represent global information.This study comprehensively surveys recent visual transformer works.We categorize them according to task scenario:backbone design,high-level vision,low-level vision and generation,and multimodal learning.Their key ideas are also analyzed.Differing from previous surveys,we mainly focus on visual transformer methods in low-level vision and generation.The latest works on backbone design are also reviewed in detail.For ease of understanding,we precisely describe the main contributions of the latest works in the form of tables.As well as giving quantitative comparisons,we also present image results for low-level vision and generation tasks.Computational costs and source code links for various important works are also given in this survey to assist further development. | Yifan Xu Huapeng Wei Minxuan Lin Yingying Deng Kekai Sheng Mengdan Zhang Fan Tang Weiming Dong Feiyue Huang Changsheng Xu | 2022 | Computational Visual Media2022，8，1： | 6 |
| 4 | The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus. | Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang | 2016 | Science China(Life Sciences)2016，59，9： | 5 |
| 5 | A survey on ensemble learning显示文摘Despite significant successes achieved in knowledge discovery,traditional machine learning methods may fail to obtain satisfactory performances when dealing with complex data,such as imbalanced,high-dimensional,noisy data,etc.The reason behind is that it is difficult for these methods to capture multiple characteristics and underlying structure of data.In this context,it becomes an important topic in the data mining field that how to effectively construct an efficient knowledge discovery and mining model.Ensemble learning,as one research hot spot,aims to integrate data fusion,data modeling,and data mining into a unified framework.Specifically,ensemble learning firstly extracts a set of features with a variety of transformations.Based on these learned features,multiple learning algorithms are utilized to produce weak predictive results.Finally,ensemble learning fuses the informative knowledge from the above results obtained to achieve knowledge discovery and better predictive performance via voting schemes in an adaptive way.In this paper,we review the research progress of the mainstream approaches of ensemble learning and classify them based on different characteristics.In addition,we present challenges and possible research directions for each mainstream approach of ensemble learning,and we also give an extra introduction for the combination of ensemble learning with other machine learning hot spots such as deep learning,reinforcement learning,etc. | Xibin DONG Zhiwen YU Wenming CAO Yifan SHI Qianli MA | 2020 | Frontiers of Computer Science2020，14，2： | 4 |
| 6 | The Promotion Effect of Low-Molecular Hydroxyl Compounds on the Nano-Photoelectrocatalytic Degradation of Fulvic Acid and Mechanism显示文摘A significant promotion effect of low-molecular hydroxyl compounds(LMHCs) was found in the nano-photoelectrocatalytic(NPEC) degradation of fulvic acid(FA),which is a typical kind of humic acid existing widely in natural water bodies,and its influence mechanism was proposed.A TiO_2 nanotube arrays(TNAs) material is served as the photoanode.Methanol,ethanediol,and glycerol were chosen as the representative of LMHCs in this study.The adsorption performance of organics on the surface of TNAs was investigated by using the instantaneous photocurrent value.The adsorption constants of FA,methanol,ethanediol,and glycerol were 43.44,19.32,7.00,and 1.30,respectively,which indicates that FA has the strongest adsorption property.The degradation performance of these organics and their mixture were observed in a thin-layer reactor.It shows that FA could hardly achieve exhausted mineralization alone,while LMHCs could be easily oxidized completely in the same condition.The degradation degree of FA,which is added LMHCs,improves significantly and the best promotion effect is achieved by glycerol.The promotion effect of LMHCs in the degradation of FA could be contributed to the formation of a tremendous amount of hydroxyl radicals in the NPEC process.The hydroxyl radicals could facilitate the complete degradation of both FA and its intermediate products.Among the chosen LMHCs,glycerol molecule which has three hydroxyls could generate the most hydroxyl radicals and contribute the best effective promotion.This work provides a new way to promote the NPEC degradation of FA and a direction to remove humus from polluted water. | Yifan Dong Jinhua Li Xuejin Li Baoxue Zhou | 2016 | Nano-Micro Letters2016，8，4： | 4 |
| 7 | H_∞ output tracking control for flight control systems with time-varying delay显示文摘For flight control systems with time-varying delay,an H∞output tracking controller is proposed.The controller is designed for the discrete-time state-space model of general aircraft to reduce the effects of uncertainties of the mathematical model,external disturbances,and bounded time-varying delay.It is assumed that the feedback-control loop is closed by the communication network,and the network-based control architecture induces time-delays in the feedback information.Suppose that the time delay has both an upper bound and a lower bound.By using the Lyapunov-Krasovskii function and the linear matrix inequality(LMI),the delay-dependent stability criterion is derived for the time-delay system.Based on the criterion,a state-feedback H∞output tracking controller for systems with norm-bounded uncertainties and time-varying delay is presented.The control scheme is applied to the high incidence research model(HIRM),which shows the effectiveness of the proposed approach. | Zhang Yingxin Wang Qing Dong Chaoyang Jiang Yifan | 2013 | Chinese Journal of Aeronautics2013，26，5： | 4 |
| 8 | The Inhibition Effect of Tert-Butyl Alcohol on the TiO_2 Nano Assays Photoelectrocatalytic Degradation of Different Organics and Its Mechanism显示文摘The inhibition effect of tert-butyl alcohol(TBA), identified as the·OH radical inhibitor, on the TiO_2 nano assays(TNA) photoelectrocatalytic oxidation of different organics such as glucose and phthalate was reported. The adsorption performance of these organics on the TNA photoelectrode was investigated by using the instantaneous photocurrent value, and the degradation property was examined by using the exhausted reaction. The results showed that glucose exhibited the poor adsorption and easy degradation performance, phthalate showed the strong adsorption and harddegradation, but TBA showed the weak adsorption and was the most difficult to be degraded. The degradation of both glucose and phthalate could be inhibited evidently by TBA. But the effect on glucose was more obvious. The different inhibition effects of TBA on different organics could be attributed to the differences in the adsorption and the degradation property. For instance, phthalate of the strong adsorption property could avoid from the capture of·OH radicals by TBA in TNA photoelectrocatalytic process. | Xuejin Li Jinhua Li Jing Bai Yifan Dong Linsen Li Baoxue Zhou | 2016 | Nano-Micro Letters2016，8，3： | 4 |
| 9 | Identification of Axial Vibration Excitation Source in Vehicle Engine Crankshafts Using an Auto-regressive and Moving Average Model显示文摘Violent axial vibration of a vehicle engine crankshaft might lead to multiple defects to the engine.Much research on mechanism and control measures has been done on engines,such as using the dynamic stiffness matrix method,rayleigh differential method,and system matrix method.But the source of axial vibration has not been identified clearly because there are many excitation factors for the axial vibration of a crankshaft,such as coupled torsional-axial vibration and coupled bending-axial vibration,etc.In order to improve the calculation reliability and identify the excitation source of axial vibration of in vehicle engine crankshafts,this paper presents a method to identify the axial vibration excitation source of crankshafts for high speed diesel engines based on an auto-regressive and moving average(ARMA) model.Through determining initial moving average variables and measuring axial /bending/torsional vibrations of a crankshaft at the free-end of a 4-cylinder diesel engine,autoregressive spectrum analysis is applied to the measured vibration signal.The results show that the axial vibration of the crankshaft is mainly excited by coupled bending vibration at high speed.But at low speed,the axial vibration in some frequencies is excited primarily by torsional excitation.Through investigation of axial vibration source of engine crankshafts,calculation accuracy of vibration can be improved significantly. | LIANG Xingyu WANG Yuesen SHU Gequn WEI Haiqiao DONG Lihui MEI Yifan | 2011 | Chinese Journal of Mechanical Engineering2011，24，6： | 3 |
| 10 | Reactions of Rare-Earth Metal Based Lewis Pairs with Azides显示文摘The reactivity of homoleptic rare-earth metal aryloxide based Lewis pairs toward organic azide substrates has been investigated herein.Treatment of RE(OAr)3(RE=La,Sm,X and Sc,Ar=2,6-'Bu2-C6H3),PEt3 and Me3SiN3 in 2:1:1 molar ratio resulted in formation of separated ion pair complexes[Me3Si-PEt3]^+[(ArO)3RE-N=N=N-RE(OAr)3]^-under mild conditions.Replacement of phosphine with the nitrogen-containing Lewis base l,4-diazabicyclo[2.2.2]octane(DABCO)produced analogous rare-earth azide complexes with[Me3Si-DABCO]+counterions.In contrast,reaction of the La(OAr)3/PEt3 Lewis pair with 1-adamantyl azide(AdN3)afforded the typical frustrated Lewis pair-type 1,1-addition product.A tetrahydrofuran ring-opening reaction was also observed for the resulting rare-earth azide complex with the[Me3Si-PEt3]+cation,with cleavage of the C—0 bond by Si/P cooperation. | Yifan Dong Kejian Chang Xin Xu | 2020 | Chinese Journal of Chemistry2020，38，6： | 3 |
| 11 | Metabolic reprogram associated with epithelial-mesenchymal transition in tumor progression and metastasis显示文摘Epithelial-mesenchymal Transition(EMT)is a de-differentiation program that imparts tumor cells with the phenotypic and cellular plasticity required for drug resistance,metastasis,and recurrence.This dynamic and reversible events is governed by a network of EMT-transcription factors(EMT-TFs)through epigenetic regulation.Many chromatin modifying-enzymes utilize metabolic intermediates as cofactors or substrates;this suggests that EMT is subjected to the metabolic regulation.Conversely,EMT rewires metabolic program to accommodate cellular changes during EMT.Here we summarize the latest findings regarding the epigenetic regulation of EMT,and discuss the mutual interactions among metabolism,epigenetic regulation,and EMT.Finally,we provide perspectives of how this interplay contributes to cellular plasticity,which may result in the clinical manifestation of tumor heterogeneity. | Yifan Wang Chenfang Dong Binhua P.Zhou | 2020 | Genes & Diseases2020，7，2： | 3 |

| 13 | High performance organic transistors and phototransistors based on diketopyrrolopyrrole-quaterthiophene copolymer thin films fabricated via low-concentration solution processing显示文摘Conjugated polymers have received considerable attentions over the past years due to their large-area potential applications via low-cost solution processing.Improving crystallinity of conjugated polymer molecules in solution-processed thin films is crucial for their efficient charge transport and thus high performance optoelectronic devices.Herein,with diketopyrrolopyrrole-quaterthiophene(PDQT)copolymer as an example,it is found that by simply reducing the solution concentration for spincoating meanwhile with the assistance of post-annealing,significantly enhanced film crystallinity with formation of typical single crystalline domains is obtained,which benefits from the enough space for better molecular assembly especially at the semiconductor/dielectric interface.High performance polymer transistors and phototransistors were finally constructed based on the optimal lowconcentration(2 mg/mL)spin-coated PDQT films(12 nm),which giving a high charge carrier mobility of 2.28 cm^2V^(-1)s^(-1)and a photoresponse on/off ratio of 2.1×10~7at V_G=0 V under white light irradiation of6 mW/cm^2.The results suggest that the bright future of PDQT crystalline films for large-area flexible integrated optoelectronic devices and the application of effective low-concentration processing approach in solution-processed organic electronics with reduced material waste. | Pengcheng Gu Mengxiao Hu Shang Ding Guangyao Zhao Yifan Yao Feng Liu Xiaotao Zhang Huanli Dong Xiangke Wang Wenping Hu | 2018 | Chinese Chemical Letters2018，29，11： | 2 |
| 14 | MobSafe:Cloud Computing Based Forensic Analysis for Massive Mobile Applications Using Data Mining显示文摘With the explosive increase in mobile apps, more and more threats migrate from traditional PC client to mobile device. Compared with traditional Win+Intel alliance in PC, Android+ARM alliance dominates in Mobile Internet, the apps replace the PC client software as the major target of malicious usage. In this paper, to improve the security status of current mobile apps, we propose a methodology to evaluate mobile apps based on cloud computing platform and data mining. We also present a prototype system named MobSafe to identify the mobile app's virulence or benignancy. Compared with traditional method, such as permission pattern based method, MobSafe combines the dynamic and static analysis methods to comprehensively evaluate an Android app. In the implementation, we adopt Android Security Evaluation Framework (ASEF) and Static Android Analysis Framework (SAAF), the two representative dynamic and static analysis methods, to evaluate the Android apps and estimate the total time needed to evaluate all the apps stored in one mobile app market. Based on the real trace from a commercial mobile app market called AppChina, we can collect the statistics of the number of active Android apps, the average number apps installed in one Android device, and the expanding ratio of mobile apps. As mobile app market serves as the main line of defence against mobile malwares, our evaluation results show that it is practical to use cloud computing platform and data mining to verify all stored apps routinely to filter out malware apps from mobile app markets. As the future work, MobSafe can extensively use machine learning to conduct automotive forensic analysis of mobile apps based on the generated multifaceted data in this stage. | Jianlin Xu Yifan Yu Zhen Chen Bin Cao Wenyu Dong Yu Guo Junwei Cao | 2013 | Tsinghua Science and Technology2013，18，4： | 2 |
| 15 | C-dots assisted synthesis of gold nanoparticles as labels to catalyze copper deposition for ultrasensitive electrochemical sensing of proteins显示文摘We report an ultrasensitive protocol for electrochemical sensing using the hydroxyl-rich C-dots assisted synthesis of gold nanoparticles(C-dots@AuNP) as labels with copper depositon reaction. The C-dots catalyzing copper deposition reaction was implemented for the first time. We constructed a sandwich-type immunosensor on the chitosan modified glassy carbon electrode(GCE) by glutaraldehyde(GA) crosslinking, with C-dots@AuNP as biolabels. Copper was deposited on the catalytic surfaces of second antibody-conjugated C-dots@AuNP nanoparticles through CuSO_4-ascorbic acid reduction, because both C-dots and AuNPs could strongly catalyze the CuSO_4 and ascorbic acid to form Cu particles, which amplified the detection signal. Then the corresponding antigen was quantified based on simultaneous chemical-dissolution/cathodic-preconcentration of copper for insitu analysis using anodic stripping square wave voltammetry(ASSWV) directly on the modified electrode. Under optimized conditions, these electrodes were employed for sandwich-type immunoanaly sis, pushing the lower limits of detection(LODs)down to the fg mL^(-1) level for human immunoglobulin G(IgG) and cardiac troponin I(cTnI), a cardiac biomarker. These novel sensors have good stability and acceptable accuracy and reproducibility, suggesting potential applications in clinical diagnostics. | Xiaoli Qin Yifan Dong Minghan Wang Zhiwei Zhu Meixian Li Xiangjian Chen Di Yang Yuanhua Shao | 2018 | Science China Chemistry2018，61，4： | 2 |
| 16 | Internal connections between dietary intake and gut microbiota homeostasis in disease progression of ulcerative colitis:a review显示文摘Ulcerative colitis(UC)is a chronic systematic inflammation disorder with increasing incidence,unknown pathogenesis,limited drug treatment,and abundant medical expenses.Dietary intake,as a daily indispensable environment factor,is closely related to UC pathogenesis and prevention.The underlying interactions between dietary intake and UC progression are implicated with the modulation of gut microbiome as well as microbial metabolites,suggesting the complex and systematic characteristics of UC.However,the triangular relationships with dietary intake,gut microbiota homeostasis,and UC have not been well summarized so far.Here we review the recent studies of dietary intake on the regulation of gut microbiome homeostasis as well as modulation of UC progression.These findings suggest that varieties in dietary patterns result in the production of diverse microbial fermentation metabolites,which contribute to gut microbiome homeostasis through multiple manipulations including immune modulation,inftammation restriction as well as epithelial barrier maintenance,thus finally determine the fate of UC progression and give implications for functional food development for prevention and treatment of UC patients. | Wen Zeng Dong He Yifan Xing Junyu Liu Nan Su Chong Zhang Yi Wang Xinhui Xing | 2021 | Food Science and Human Wellness2021，10，2： | 2 |
| 17 | Perovskite solar cell towards lower toxicity: a theoretical study of physical lead reduction strategy显示文摘The huge performance enhancements of the organometal halide perovskite solar cells(OHPSCs) have appealed enormous attention within recent ten years. Although the rapid growth of the device power conversion efficiency(PCE) has attained over 25%, the contamination of health-hazardous components still holds back its sustainable applications. To reduce the lead usage, many groups have tried chemical lead reduction solutions: substituting the lead by other group 14 metal elements to realize the low-lead OHPSCs. Unfortunately, neither the PCE nor the stability, low-lead OHPSCs all lag far behind the state-ofthe-art conventional lead-based OHPSCs. In this work, we present a physical lead reduction(PLR) concept by reducing the perovskite film thickness to restrict the perovskite hazard risk with minor scarification in device performances. Through the simulation of transfer matrix model, we theoretically demonstrated that by introducing the optical space layer, the device PCE could maintain 96% of the original maximum value while attenuating the perovskite film thickness to one-third. This means that the usage of lead can be reduced by $70% with PLR concept, which could have broad appeal as a new lead reduction strategy towards high performance OHPSCs. | Yifan Zheng Rui Su Zhaojian Xu Deying Luo Hua Dong Bo Jiao Zhaoxin Wu Qihuang Gong Rui Zhu | 2019 | Science Bulletin2019，64，17： | 2 |
