| 1 | Convolutional neural networks for time series classification显示文摘Time series classification is an important task in time series data mining, and has attracted great interests and tremendous efforts during last decades. However, it remains a challenging problem due to the nature of time series data: high dimensionality,large in data size and updating continuously. The deep learning techniques are explored to improve the performance of traditional feature-based approaches. Specifically, a novel convolutional neural network(CNN) framework is proposed for time series classification. Different from other feature-based classification approaches,CNN can discover and extract the suitable internal structure to generate deep features of the input time series automatically by using convolution and pooling operations. Two groups of experiments are conducted on simulated data sets and eight groups of experiments are conducted on real-world data sets from different application domains. The final experimental results show that the proposed method outperforms state-of-the-art methods for time series classification in terms of the classification accuracy and noise tolerance. | Bendong Zhao Huanzhang Lu Shangfeng Chen Junliang Liu Dongya Wu | 2017 | Journal of Systems Engineering and Electronics2017，28，1： | 33 |
| 2 | Cenozoic Evolution of Sediments and Climate Change and Response to Tectonic Uplift of the Northeastern Tibetan Plateau显示文摘Through a comprehensive study of magnetostratigraphy and sedimentology of several basins in the northeastern Tibetan Plateau, we reveal that the study area mainly experienced six tectonic uplift stages at approximately 52 Ma, 34–30 Ma, 24–20 Ma, 16–12 Ma, 8–6 Ma, and 3.6–2.6 Ma. Comprehensive analyses of pollen assemblages from the Qaidam, Linxia, Xining, and West Jiuquan Basins show that the northeastern Tibetan Plateau has undergone six major changes in vegetation types and climate: 50–40 Ma for the warm-humid forest vegetation, 40–23 Ma for the warm-arid and temperate-arid forest steppe vegetation, 23–18.6 Ma for the warm-humid and temperatehumid forest vegetation, 18.6–8.5 Ma for the warm-humid and cool-humid forest steppe vegetation, 8.6–5 Ma for the temperate sub-humid savanna steppe vegetation, and 5–1.8 Ma for the cold-arid steppe vegetation. Comprehensive comparisons of tectonic uplift events inferred from sedimentary records, climatic changes inferred from pollen, and global climate changes show that in the northeastern Tibetan Plateau the climate in the Paleogene at low altitude was mainly controlled by the global climate change, while that in the Neogene interval with high altitude landscapes of mountains and basins is more controlled by altitude and morphology. | LIANG Xia JI Junliang LU Jingfang KE Xue AI Keke XU Yadong SONG Bowen | 2014 | Acta Geologica Sinica(English Edition)2014，88，3： | 5 |
| 3 | Layer-by-layer slot-die coated high-efficiency organic solar cells processed using twin boiling point solvents under ambient condition显示文摘Layer-by-layer (LbL) strategy has been developed to form bulk heterojunction (BHJ) structure for processing efficient organic solar cells (OSCs). Herein, LbL slot-die coating with twin boiling point solvents (TBPS) strategy was developed to fabricate highly efficient OSCs, which matches with large-scale, high throughput roll-to-roll (R2R) industrialized mass process. The TBPS strategy could produce high-quality thin film without any additive, leading to the optimized vertical phase separation with interpenetrating nanostructures, as well as the enhanced charge transport and extraction. Thus, the power conversion efficiency up to 14.42% was achieved for [(2,6-(4,8-bis(5-(2-ethylhexyl-3-fluoro)thiophen-2-yl)-benzo [1,2-b:4,5-b′]dithiophene))-alt-(5,5-(1′,3′-di-2-thienyl-5′,7′-bis(2-ethylhexyl)benzo[1′,2′-c:4′,5′-c′]dithiophene-4,8-dione)]:2,2′-((2Z,2′Z)-((12,13-bis(2-ethylhexyl)-3,9-diundecyl-12,13-dihydro-[1,2,5]thiadiazolo[3,4-e]thieno[2″,3″:4″,5″]thieno[2′,3′:4,5]pyrrolo[3,2-g]thieno[2′,3′:4,5]thieno[3,2-b]indole-2,10-diyl)bis(methanylylidene)) bis(5,6-difluoro-3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile (PM6:Y6) OSCs fabricated via sequentially LbL slot-die coating using the TBPS strategy under ambient condition. The research provides a potential route for industrialized production of high-efficiency and large-area OSC devices. | Yu Yang Erming Feng Hengyue Li Zichao Shen Wanrong Liu Jingbo Guo Qun Luo Jidong Zhang Guanghao Lu Changqi Ma Junliang Yang | 2021 | Nano Research2021，14，11： | 1 |
| 4 | Bioactive glass promotes the barrier functional behaviors of keratinocytes and improves the Re-epithelialization in wound healing in diabetic rats显示文摘Upon skin injury,re-epithelialization must be triggered promptly to restore the integrity and barrier function of the epidermis.However,this process is often delayed or interrupted in chronic wounds like diabetic foot ulcers.Considering that BG particles can activate multiple genes in various cells,herein,we hypothesized that bioactive glass(BG)might be able to modulate the barrier functional behaviors of keratinocytes.By measuring the transepithelial electrical resistance(TEER)and the paracellular tracer flux,we found the 58S-BG extracts substantially enhanced the barrier function of keratinocyte monolayers.The BG extracts might exert such effects by promoting the keratinocyte differentiation and the formation of tight junctions,as evidenced by the increased expression of critical differentiation markers(K10 and involucrin)and TJ protein claudin-1,as well as the altered subcellular location of four major TJ proteins(claudin-1,occludin,JAM-A,and ZO-1).Besides,the cell scratch assay showed that BG extracts induced the collective migration of keratinocytes,though they did not accelerate the migration rate compared to the control.The in vivo study using a diabetic rat wound model demonstrated that the BG extracts accelerated the process of re-epithelialization,stimulated keratinocyte differentiation,and promoted the formation of tight junctions in the newly regenerated epidermis.Our findings revealed the crucial effects of BGs on keratinocytes and highlighted its potential application for chronic wound healing by restoring the barrier function of the wounded skin effectively. | Fengling Tang Junliang Li Weihan Xie Yunfei Mo Lu Ouyang Fujian Zhao Xiaoling Fu Xiaofeng Chen | 2021 | Bioactive Materials2021，6，10： | 1 |
| 5 | Micro-motion dynamics analysis of ballistic targets based on infrared detection显示文摘The dynamic characteristics related to micro-motions,such as mechanical vibration or rotation, play an essential role in classifying and recognizing ballistic targets in the midcourse, and recent researches explore ways of extracting the micro-motion features from radar signals of ballistic targets. In this paper, we focus on how to investigate the micro-motion dynamic characteristics of the ballistic targets from the signals based on infrared(IR) detection, which is mainly achieved by analyzing the periodic fluctuation characteristics of the target IR irradiance intensity signatures.Simulation experiments demonstrate that the periodic characteristics of IR signatures can be used to distinguish different micromotion types and estimate related parameters. Consequently, this is possible to determine the micro-motion dynamics of ballistic targets based on IR detection. | Junliang Liu Yanfang Li Shangfeng Chen Huanzhang Lu Bendong Zhao | 2017 | Journal of Systems Engineering and Electronics2017，28，3： | 1 |

| 9 | Forecasting Multi-Step Ahead Monthly Reference Evapotranspiration Using Hybrid Extreme Gradient Boosting with Grey Wolf Optimization Algorithm显示文摘It is important for regional water resources management to know the agricultural water consumption information several months in advance.Forecasting reference evapotranspiration(ET_(0))in the next few months is important for irrigation and reservoir management.Studies on forecasting of multiple-month ahead ET_(0) using machine learning models have not been reported yet.Besides,machine learning models such as the XGBoost model has multiple parameters that need to be tuned,and traditional methods can get stuck in a regional optimal solution and fail to obtain a global optimal solution.This study investigated the performance of the hybrid extreme gradient boosting(XGBoost)model coupled with the Grey Wolf Optimizer(GWO)algorithm for forecasting multi-step ahead ET_(0)(1-3 months ahead),compared with three conventional machine learning models,i.e.,standalone XGBoost,multi-layer perceptron(MLP)and M5 model tree(M5)models in the subtropical zone of China.The results showed that theGWO-XGB model generally performed better than the other three machine learning models in forecasting 1-3 months ahead ET_(0),followed by the XGB,M5 and MLP models with very small differences among the three models.The GWO-XGB model performed best in autumn,while the MLP model performed slightly better than the other three models in summer.It is thus suggested to apply the MLP model for ET_(0) forecasting in summer but use the GWO-XGB model in other seasons. | Xianghui Lu Junliang Fan Lifeng Wu Jianhua Dong | 2020 | Computer Modeling in Engineering & Sciences2020，，11： | 1 |

| 15 | 4-11 Determination of Target Thickness and Luminosity from Beam Energy Losses at HIRFL-CSRe Internal Target显示文摘The experiments with an internal target at a storage ring have many advantages. However, it is difficult to determine the absolute cross section of a reaction where luminosity cannot be simply established through macroscopic measurements. Here we present an experimental determination of the effective target thickness from the beam energy losses at the internal target in HIRFL-CSRe. The measurements here are expected to provide the accurate target thickness and luminosity for the absolute cross-section study on future internal target experiments, and also provide some reference values for the study of beam loss mechanism of the heavy ion at HIRFL-CSRe. | Shao Caojie Yu DeYang Lu Rongchun Xue Yingli Wang Wei Yang Bian Zhang Mingwu Liu Junliang Song Zhangyong Cai Xiaohong | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |

| 17 | Impact of surface-reflected seismic waves on the seismic isolation performance of circular tunnel isolation layers显示文摘Seismic isolation is an effective strategy to mitigate the risk of seismic damage in tunnels.However,the impact of surface-reflected seismic waves on the effectiveness of tunnel isolation layers remains under explored.In this study,we employ the wave function expansion method to provide analytical solutions for the dynamic responses of linings in an elastic half-space and an infinite elastic space.By comparing the results of the two models,we investigate the seismic isolation effect of tunnel isolation layers induced by reflected seismic waves.Our findings reveal significant differences in the dynamic responses of the lining in the elastic half-space and the infinitely elastic space.Specifically,the dynamic stress concentration factor(DSCF)of the lining in the elastic half-space exhibits periodic fluctuations,influenced by the incident wave frequency and tunnel depth,while the DSCF in the infinitely elastic space remain stable.Overall,the seismic isolation application of the tunnel isolation layer is found to be less affected by surface-reflected seismic waves.Our results provide valuable insights for the design and assessment of the seismic isolation effect of tunnel isolation layers. | LU Jiahui LUO Junjie HUANG Xiangyun HONG Junliang HE YanXin ZHOU Fulin | 2024 | Journal of Mountain Science2024，21，3： | 0 |
| 18 | 4-18 Single and Double Electron Capture by Fast Xe54+ from Kr and Xe显示文摘When an energetic highly charged ion (HCI) collides with an atom, the target electrons may be captured by theprojectile ion, either radiatively or non-radiatively. During a radiative electron capture (REC), a target electronis transferred to the projectile accompanying with a photon emission, which carries away the excess energy andmomentum. During a non-radiative electron capture (NRC), the energy and momentum conservations are ensuredby the target nucleus[1]. If the captured electrons are populated in excited states, photons maybe emitted duringthe following stabilization processes, and therefore the X-ray spectrum can provide information about the initialpopulation. However, if a solid target is employed, the single-collision condition cannot be ensured when consideringthe capture processes, as well as strong background will be produced[2]. With the development of heavy ioncooling storage rings, the experimental luminance is enhanced by the strong ion beams when a gaseous target isprerequisite[3]. | Yu Deyang Shao Caojie Lu Rongchun Wang Wei Liu Junliang Xue Yingli Song Zhangyong Zhang Mingwu Yang Bian Ruan Fangfang Cai Xiaohong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 19 | 4-19 Double K-shell Ionization of Kr Induced by Swift Xe54+ Ions显示文摘Double K-shell ionization of atoms by collisions with charged ions is one of typical two-electron processes andattracts considerable attention both in term of basic theory and experiment. Radiative de-excitation of the doubleK-shell vacancy states of atoms leads to the emission of so called K X-ray hyper-satellites (Kh,Kh . . . )[1], whichgives us the insight into the decay modes of multiply ionized ions as well as the ionization processes during ion-atomcollisions. Contrary to the long-winded and difficult experiments with heavy target due to the low detection efficiencyof K X-ray hyper-satellites with crystal spectrometers[2??4], the bulk of knowledge concerning double K-shellionization in ion-atom collisions has been obtained for light target. | Shao Caojie Yu Deyang Wang Wei Xue Yingli Zhang Mingwu Yang Bian Song Zhangyong Lu Rongchun Liu Junliang Cai Xiaohong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 20 | 4-22 A Charge Sensitive Spectroscopy Ampli er for Position Sensitive Micro-channel Plate Detectors显示文摘Position sensitive Micro-Channel Plate (MCP) detectors are widely used for detection of particles like electronsand ions[1]. A previous work shows that integrating the electronics into an MCP detector is an optimal noisereduction method[2]. In this paper, we present a compact, low noise charge sensitive spectroscopy ampli er whichcould be integrated into MCP detectors for charge divide readout schemes.A logic diagram of the spectroscopy amplier is shown in Fig. 1. It is composed of a charge sensitive preamplier(PA), a pulse shaper (PS) and a liner amplier (LA). The PS is implemented with a four stage Bessel low passactive lter in a Sallen-Key topology[3]. | Wang Wei Yu Deyang Liu Junliang Lu Rongchun Cai Xiaohong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
