| 1 | Fusion tracking in color and infrared images using joint sparse representation显示文摘Currently sparse signal reconstruction gains considerable interest and is applied in many fields. In this paper, a similarity induced by joint sparse representation is designed to construct the likelihood function of particle filter tracker so that the color visual spectrum and thermal spectrum images can be fused for object tracking. The proposed fusion scheme performs joint sparse representation calculation on both modalities and the resultant tracking results are fused using min operation on the sparse representation coefficients. In addition, a co-learning approach is proposed to update the reference templates of both modality and enhance the tracking robustness. The proposed fusion scheme outperforms state-of-the-art approaches, and its effectiveness is verified using OTCBVS database. | LIU HuaPing SUN FuChun | 2012 | Science China(Information Sciences)2012，55，3： | 24 |
| 2 | Impending HRT wave precursors to the Wenchuan M_s8.0 earthquake and methods of earthquake impending prediction by using HRT wave显示文摘We deployed four geo-electric monitoring stations in Sichuan and Yunnan provinces from 2004, using the new generation of equipment (PS-100) and technologies to capture the HRT wave earthquake precursor. Before the Wenchuan Ms8.0 earthquake, we recorded the HRT wave precursor at the only operating station in Hongge (HG, Δ=465 km) and found that significant impending signal had been recorded at the station in the early morning ( 0―5 am) of 12th of May, 2008. The precursor for this earthquake is consistent with precursors recorded for other strong earthquakes. The measured physical properties (geo-resistivity and telluric-current) show tidal wave period oscillations from several days to several months before the earthquakes and the amplitude of such HT oscillation increases significantly towards the occurrence of an earthquake. These HT and RT waves from the epicenter have a causal relationship with the earthquakes that happened several days later. The arrival time of two RT waves is proportional to the distance from the station to the epicenter. The estimated natural decay of the amplitude is correlated with the natural period (T0) of the earthquake fault, which is proportional to the fault length. From this relationship, we can predict the earthquake magnitude. For magnitude 6―9 earthquakes, the natural period is about 1―6 hours. Such oscillation comes from the epicenter area and they can propagate several thousand kilometers in the Earth's crust. Before a strong earthquake in the shallow crust, the conductive pore fluid will experience major changes before the fault rapture. Such fluid change will emit an oscillation in the pore fluid pressure. This is the mechanism for the HRT wave generation. Since the China Earthquake Administration funded the HRT wave short-term earth-quake prediction project in 2003, the first record of HRT precursor wave has been recorded from the 2004-12-26 Sumatra Mw9.0 earthquake with the largest epicentre distance Δ=2900 km. Thereafter, we have captured HRT waves from more than twenty strong earthquakes, which are well-matched and show repeatability, consistency and regularity. All our observation with the HRT waves demonstrate that HRT wave precursors to earthquakes indeed exist. Strong earthquakes can be predicted and short-term and impending earthquake prediction is achievable in the very near future. From all the observations, including the ones at HG station from Wenchuan Ms8.0 earthquake, we conclude that using HRT wave to predict earthquakes is feasible. | QIAN FuYe ZHAO BiRu QIAN Wei ZHAO Jian HE ShiGen ZHANG HongKui LI ShiYu LI ShaoKun YAN GuLiang WANG ChengMin SUN ZhenKai ZHANG DongNing LU Jun ZHANG Ping YANG GuoJun SUN JiaLin GUO ChunSheng TANG YuXiong XU JianMing XIA KunTao JU Hang YIN BangHong LI Ming YANG DongSheng QI WeiLuo HE TaiMing GUAN HuaPing ZHAO YuLin | 2009 | Science China Earth Sciences2009，52，10： | 8 |
| 3 | Microstructure Evolution and Tensile Properties of Ti_3Al/Ni-based Superalloy Welded Joint显示文摘In the present work,the dissimilar joining of a Ti_3AI-based alloy to a Ni-based superalloy was attempted by gas tungsten arc(GTA) welding technology.Sound joints were successfully achieved by using a Cu—Ni alloy as filler material.According to X-ray energy dispersive spectroscopy and X-ray diffraction analysis results three transitional layers at the weld/Ti_3AI interface were verified as follows:Ti_2AINb phase dissolved with Cu and Ni;AI(Cu,Ni)_2Ti,(Cu,Ni)_2Ti and(Nb,Ti) solid solution;Cu-rich phase and a complex multi-element phase.The In718/weld interface is characterized by solid solutions of Ni,Cu,Cr,Fe and Nb.The average tensile strength of the as-welded joints at room temperature is 1 63 MPa,and after a post—weld heat treatment it is increased slightly to 177 MPa.The fracture occurred at the surfacial layer of the joined Ti_3AI base alloy,indicating that the Ti_2AINb layer dissolved with Cu and Ni is the weak link of the Ti_3AI/ln71 8 joint. | Bingqing Chen Huaping Xiong Bingbing Sun Siyi Tang Shaoqing Guo Xuejun Zhang | 2014 | Journal of Materials Science & Technology2014，30，7： | 7 |
| 4 | Clinicopathological analysis of metaplastic meningioma: report of 15 cases in Huashan Hospital显示文摘Objective: Metaplastic meningioma is a rare subtype of benign meningiomas, classified as WHO grade I with well prognosis. Here we presented our experiences on 15 cases of metaplastic meningioma, to investigate the clinicopathological features, therapies and prognosis of these cases. Methods: 15 patients underwent surgical treatment for intracranial metaplastic meningioma between 2001 and 2010 at Neurosurgery Department of Huashan Hospital, Shanghai, China. The clinical data, radiological manifestation, treatment strategy, pathological findings and prognosis of all patients were analyzed retrospectively. Results: Among the 15 cases (10 males and 5 females), the age ranged from 22 to 74 years old (the mean age was 50.67-year old). The clinical manifestations include headache, dizziness, seizure attack, vision decrease, and weakness of bilateral lower limbs. All the patients received surgical treatment, combined with radiotherapy in some cases. In the follow-up period, recurrence occurred in 2 cases, of which 1 patient died of other system complications. Conclusions: Metaplastic meningiomas are characterized by focal or widespread mesenchymal differentiation with formation of bone, cartilage, fat, and xanthomatous tissue elements. Surgical removal is the optimal therapy, and the overall prognosis is well. But recurrence may occur in some cases, thus radiotherapy is necessary for such kind of patients. | Hailiang Tang Huaping Sun Hong Chen Ye Gong Ying Mao Qing Xie Liqian Xie Mingzhe Zheng Daijun Wang Hongda Zhu Xiaoming Che Ping Zhong Kang Zheng Shiqi Li Weimin Bao Jianhong Zhu Xuanchun Wang Xiaoyuan Feng Xiancheng Chen Liangfu Zhou | 2013 | Chinese Journal of Cancer Research2013，25，1： | 6 |
| 5 | Skill Learning for Human-Robot Interaction Using Wearable Device显示文摘With the accelerated aging of the global population and escalating labor costs, more service robots are needed to help people perform complex tasks. As such, human-robot interaction is a particularly important research topic. To effectively transfer human behavior skills to a robot, in this study, we conveyed skill-learning functions via our proposed wearable device. The robotic teleoperation system utilizes interactive demonstration via the wearable device by directly controlling the speed of the motors. We present a rotation-invariant dynamicalmovement-primitive method for learning interaction skills. We also conducted robotic teleoperation demonstrations and designed imitation learning experiments. The experimental human-robot interaction results confirm the effectiveness of the proposed method. | Bin Fang Xiang Wei Fuchun Sun Haiming Huang Yuanlong Yu Huaping Liu | 2019 | Tsinghua Science and Technology2019，24，6： | 3 |
| 6 | Linear dynamic system method for tactile object classification显示文摘Lots of tactile sequences can be obtained by using a dexterous hand for grasping different objects.The ability of robotic environmental perception and dexterous manipulation will be significantly improved after these tactile sequences are correctly classified.Therefore,tactile sequences are separated into series of subgroups,and a method based on linear dynamical system(LDS)is used to extract features.Since these LDSs lie in nonEuclidean space,the Martin distance,which is a measurement different from Euclidean distance,is applied to calculate the distance between two LDSs,and the K-Medoid algorithm is used for clustering.The codebook is obtained after clustering and is used to represent time sequences to get a Bag-of-System(Bo S).Then the Bo S and labels are sent to Extreme Learning Machine(ELM)to train a classifier.Finally,three databases,KTH-7,KTH-10 and TSH-8 are used to evaluate our algorithm. | MA Rui LIU HuaPing SUN FuChun YANG QingFen GAO Meng | 2014 | Science China(Information Sciences)2014，57，12： | 3 |
| 7 | Intraoperative ultrasound assistance in resection of intracranial meningiomas显示文摘Objective: Intracranial meningiomas, especially those located at anterior and middle skull base, are difficult to be completely resected due to their complicated anatomy structures and adjacent vessels. It's essential to locate the tumor and its vessels precisely during operation to reduce the risk of neurological deficits. The purpose of this study was to evaluate intraoperative ultrasonography in displaying intracranial meningioma and its surrounding arteries, and evaluate its potential to improve surgical precision and minimize surgical trauma. Methods: Between December 2011 and January 2013, 20 patients with anterior and middle skull base meningioma underwent surgery with the assistance of intraoperative ultrasonography in the Neurosurgery Department of Shanghai Huashan Hospital. There were 7 male and 13 female patients, aged from 31 to 66 years old. Their sonographic features were analyzed and the advantages of intraoperative ultrasonography were discussed. Results: The border of the meningioma and its adjacent vessels could be exhibited on intraoperative ultrasonography. The sonographic visualization allowed the neurosurgeon to choose an appropriate approach before the operation. In addition, intraoperative ultrasonography could inform neurosurgeons about the location of the tumor, its relation to the surrounding arteries during the operation, thus these essential arteries could be protected carefully. Conclusions: Intraoperative ultrasonography is a useful intraoperative technique. When appropriately applied to assist surgical procedures for intracranial meningioma, it could offer very important intraoperative information (such as the tumor supplying vessels) that helps to improve surgical resection and therefore might reduce the postoperative morbidity. | Hailiang Tang Huaping Sun Liqian Xie Qisheng Tang Ye Gong Ying Mao Qing Xie Mingzhe Zheng Daijun Wang Hongda Zhu Jianhong Zhu Xiaoyuan Feng Zhenwei Yao Xiancheng Chen Liangfu Zhou | 2013 | Chinese Journal of Cancer Research2013，25，3： | 3 |
| 8 | Fintech,regtech,and financial development:evidence from China显示文摘This study investigates the influence of fintech on developments in China’s financial sector across 290 cities and 31 provinces between 2011 and 2018.Using a two-stage least squares instrumental variable regression approach and correcting for cross-sectional dependency,simultaneity,and endogeneity of regressors,the results establish a positive link between fintech and financial development.Our findings show that fintech supports financial sector development by enhancing access(loans),depth(deposits),and savings within China’s financial institutions.We also show that the emergence of fintech in the area of financial regulation(regulatory technology:regtech)can significantly improve financial development outcomes.Therefore,it is imperative for regulators to pursue policies that balance growth in the fintech sector while mitigating the associated risks.In addition,we use the difference-in-differences approach to show that policy measures such as interest rates liberalization also positively impacted finan-cial development during the analysis period.In our conclusion,we suggest a policy framework for balanced fintech sector growth in developing countries. | Tadiwanashe Muganyi Linnan Yan Yingkai Yin Huaping Sun Xiangbin Gong Farhad Taghizadeh-Hesary | 2022 | Financial Innovation2022，8，1： | 3 |
| 9 | Microstructures and mechanical properties of Ti_3Al/Ni-based superalloy joints arc welded with Ti–Nb and Ti–Ni–Nb filler alloys显示文摘Dissimilar joining of Ti3Al-based alloy to Ni-based superalloy has been carried out using gas tungsten arc(GTA) welding technology with Ti–Nb and Ti–Ni–Nb filler alloys.The joint welded with the Ti–Nb filler alloy contained much less interfacial brittle phases than the one using the Ti–Ni–Nb filler alloy.The average room-temperature tensile strength of the joint welded with Ti–Nb was 202 MPa and the strength value of the one welded with Ti–Ni–Nb was 128 MPa.For both fillers,the weak links of the dissimilar joints were the weld/In718 interfaces.The presence of TiNi,TiNi3 and Ni3Nb intermetallic compounds in the joint welded with Ti–Ni–Nb induced microcracks at the weld/In718 interface and deteriorated the mechanical properties of the joint.And the adoption of the Ti–Nb filler alloy decreased the formation tendency of interfacial brittle phases to some extent and thus enhanced the tensile strength of the joint. | Bingqing Chen Huaping Xiong Bingbing Sun Siyi Tang Borui Du Neng Li | 2014 | Progress in Natural Science:Materials International2014，24，4： | 3 |
| 10 | Highly-rough surface carbon nanofibers film as an effective interlayer for lithium–sulfur batteries显示文摘Lithium–sulfur(Li–S)battery with a new configuration is demonstrated by inserting a flexible nitrogen-doping carbon nanofiber(N-CNFs)interlayer between the sulfur cathode and the separator.The N-CNFs film with high surface roughness and surface area is fabricated by electrospinning and a subsequent calcination process.The N-CNFs film interlayer not only effectively traps the shuttling migration of polysulfides but also gives the whole battery reliable electronic conductivity,which can effectively enhance the electrochemical performance of Li–S batteries.Finally,Li–S batteries with long cycling stability of 785 mAh/g after 200 cycles and good rate capability of 573 mAh/g at 5 C are achieved. | Hongfan Zhu Mo Sha Huaping Zhao Yuting Nie Xuhui Sun Yong Lei | 2020 | Journal of Semiconductors2020，41，9： | 3 |

| 17 | Fabric Recognition Using Zero-Shot Learning显示文摘In this work, we use a deep learning method to tackle the Zero-Shot Learning(ZSL) problem in tactile material recognition by incorporating the advanced semantic information into a training model. Our main technical contribution is our proposal of an end-to-end deep learning framework for solving the tactile ZSL problem. In this framework, we use a Convolutional Neural Network(CNN) to extract the spatial features and Long Short-Term Memory(LSTM) to extract the temporal features in dynamic tactile sequences, and develop a loss function suitable for the ZSL setting. We present the results of experimental evaluations on publicly available datasets, which show the effectiveness of the proposed method. | Feng Wang Huaping Liu Fuchun Sun Haihong Pan | 2019 | Tsinghua Science and Technology2019，24，6： | 1 |
| 18 | Electroencephalogram evidence for mirror neuron activity during the observation of drawn hand motion显示文摘The present study used electroencephalography to examine mu rhythm suppression (a putative index of human mirror neuron system activation) at frontal sites (F3, Fz and F4), central sites (C3, Cz and C4), parietal sites (P3, Pz and P4) and occipital sites (O1 and O2), while subjects observed real hand motion (real hand motion condition) and illustrative depictions of hand motion (drawn hand motion condition). Experimental data revealed that mu rhythm suppression was exhibited in the mirror neuron system when subjects observed both real and drawn hand motion. Moreover, the mu rhythm recorded at the F3, Fz, F4, and Pz poles was significantly suppressed while observing both stimulus types, but no obvious mu suppression occurred at the O1, O2 and O3 poles. These results suggest that the observation of drawings of human hand actions can activate the human mirror neuron system. This evidence supports the hypothesis that the mirror neuron system may be involved in intransitively abstract action understanding. | Huaping Zhu Yaoru Sun Wenya Duan | 2011 | Neural Regeneration Research2011，6，18： | 1 |
| 19 | Involvement of mitogen-activated protein kinase pathways in N-methyl-D-aspartate-induced excitotoxicity显示文摘Previous studies have shown that mitogen-activated protein kinase(MAPK) signaling pathways are involved in N-methyl-D-aspartate(NMDA)-mediated excitotoxicity.However,a systematic observation or analysis of the role of these various MAPK pathways in excitotoxicity processes does not exist.The present study further evaluated the role and contribution of three MAPK pathways extracellular signal-regulated kinase,c-Jun N-terminal kinase,and p38 MAPK in an NMDA-mediated excitotoxicity model using MAPK-specific inhibitor.Results demonstrated that c-Jun N-terminal kinase inhibitor SP600125 and/or p38 MAPK inhibitor SB203580 inhibited NMDA-induced reduction in cell viability,as well as reduced NMDA-induced lactate dehydrogenase leakage and reactive oxygen species production.However,PD98059,an inhibitor of extracellular signal-regulated kinase,did not influence this model.Results demonstrated an involvement of c-Jun N-terminal kinase and p38 MAPK,but not extracellular signal-regulated kinase,in NMDA-mediated excitotoxicity in cortical neurons. | Xiaorong Yang Ping Sun Huaping Qin Rui Wang Ye Wang Ruihong Shi Xin Zhao Ce Zhang | 2011 | Neural Regeneration Research2011，6，4： | 1 |
