| 1 | Occurrence of Neoproterozoic low-grade metagranite in the western Beihuaiyang zone,the Dabie orogen显示文摘Based on detailed field investigations and petrographic observations,we discovered Neoproterozoic-emplaced granite from the metavolcanics of the Dingyuan Formation in the western Beihuaiyang zone,the Dabie orogen. This study reports the results of zircon U-Pb dating and preliminary petrographic observations on two metagranite samples. The studied rocks experienced epidote-amphibolite facies metamorphism and strong structural deformation. Their U-Pb ages are 726 ± 6 and 758 ± 12 Ma,respectively,similar to those for the Luzhenguan complex in the eastern segment of the Beihuaiyang zone. In combination with previously determined 635 ± 5 Ma low-grade metagabbro,this study suggests the occurrence of at least two types of Neoproterozoic intrusive rocks in the Beihuaiyang zone,the northern margin of the South China Block (SCB):726-758 Ma metagranite and 635 Ma metagabbro. These rocks occur within the metamorphosed Ordovician volcanic zone (originally named the Dingyuan Formation) and are in tectonic contact to each other,but they formed in different tectonic settings. The protolith ages for the Neoproterozoic low-grade metaigneous rocks are in good agreement not only with ages for two episodes of mid-and late-Neoproterozoic mafic and felsic magmatism in the Suizhou and Zaoyang area,Hubei Province,but also agree with protolith ages of ultrahigh-pressure metaigneous rocks in the Dabie-Sulu orogenic belt. In view of their tectonic relationships to country rocks,it appears that these Neoproterozoic low-grade rocks are exotic and they may have been detached and scraped from subducting SCB crust in the early Triassic during the initial continental subduction,and thrusted over Paleozoic metamorphosed rocks in the southern margin of the North China Block during continental collision. | LIU YiCan LIU LiXiang GU XiaoFeng LI ShuGuang SONG Biao | 2010 | Chinese Science Bulletin2010，55，30： | 10 |
| 2 | Using repeated precise gps campaigns for research of present-day crustal movement and strain in the Qinghai-Tibetan Plateau显示文摘The problem of crustal movement in the Qing-hai-Tibetan Plateau is a hotstopic of the present-day international geodetic world. GPS observations in 1993, 1995 and 1997 are used to survey the three-dimensional displacement of GPS monitoring station in the Qinghai-Tibetan Plateau, and to calculate and analyze the present-day crustal movement and strain in the Qinghai-Tibetan Plateau. The result of repeated campaign shows that the crustal movement in the Qinghai-Tibetan Plateau is still compressing in the north and south directions, extending in the west and east directions, and uplifting in the vertical direction. The relative convergence velocity of the Himalayan block is approximately (19.5±1.7)mm/a, the strain velocity is about (5.5±6.0) mm/a, and the uplifting velocity is some (7.6±5.2) mm/a. The compression velocity of the Tibet block relative to Golmud in the north and south directions is (9.3±4.6) mm/a, the strain velocity of the middle part in the west and east directions is (15.6±6.3) mm/a, | LIU Jingnan XU Caijun SONG Chenghua SHI Chuang JIANG Weiping DONG Lixiang | 2001 | Chinese Science Bulletin2001，46，8： | 8 |

| 4 | Discovery of Late Carboniferous strata and their tectonic significance in the southern margin of the North China Block(Huoqiu and Gushi areas)显示文摘Late Carboniferous fossils(such as Boultonia? sp., Tabulata, and spiriferoid specimens with smooth shells), bioclastic material(such as crinoid stems and sponge fragments), and Late Ordovician microfossils of the conodont Belodina have been discovered in the lower part of the strata typically referred to as the Neoproterozoic on the boundary of the provinces of Anhui and Henan in the southern margin of the North China Block. These findings prove that the strata contain macrofossils belonging to the Late Carboniferous, which belonged to a carbonate debris flow deposit that was formed under a carbonate slope environment. The conodont fossils might belong to a detrital deposit. Thus, it is possible to reset the stratigraphic sequences and tectonic attributes belonging to the North Huaiyang tectonic belt and limit the Shouxian fault to the boundary between the Dabie Orogen and North China Block. | Shuangying Li Zaifei Ji Song Wang Cheng Cheng Lixiang Guo Dongdong Yang Hao Niu | 2014 | Chinese Science Bulletin2014，59，7： | 3 |
| 5 | URMG: Enhanced CBMG-Based Method for Automatically Testing Web Applications in the Cloud显示文摘To satisfy the rapid growth of cloud technologies, a large number of web applications have been developed and deployed, and these applications are being run in clouds. Due to the scalability provided by clouds, a single web application may be concurrently visited by several millions or billions of users. Thus, the testing and performance evaluations of these applications are increasingly important. User model based evaluations can significantly reduce the manual work required, and can enable us to determine the performance of applications under real runtime environments. Hence, it has become one of the most popular evaluation methods in both industry and academia. Significant efforts have focused on building different kinds of models using mining web access logs, such as Markov models and Customer Behavior Model Graph(CBMG). This paper proposes a new kind of model, named the User Representation Model Graph(URMG), which is built based on CBMG. It uses an algorithm to refine CBMG and optimizes the evaluations execution process. Based on this model, an automatic testing and evaluation system for web applications is designed, implemented, and deployed in our test cloud, which is able to execute all of the analysis and testing operations using only web access logs. In our system, the error rate caused by random access to applications in the execution phase is also reduced, and the results show that the error rate of the evaluation that depends on URMG is 50% less than that which depends on CBMG. | Xiaolin Xu Hai Jin Song Wu Lixiang Tang Yihong Wang | 2014 | Tsinghua Science and Technology2014，19，1： | 2 |
| 6 | The Msi1-mTOR pathway drives the pathogenesis of mammary and extramammary Paget’s disease显示文摘Mammary and extramammary Paget’s Diseases(PD)are a malignant skin cancer characterized by the appearance of Paget cells.Although easily diagnosed,its pathogenesis remains unknown.Here,single-cell RNA-sequencing identified distinct cellular states,novel biomarkers,and signaling pathways—including mTOR,associated with extramammary PD.Interestingly,we identified MSI1 ectopic overexpression in basal epithelial cells of human PD skin,and show that Msi1 overexpression in the epidermal basal layer of mice phenocopies human PD at histopathological,single-cell and molecular levels.Using this mouse model,we identified novel biomarkers of Paget-like cells that translated to human Paget cells.Furthermore,single-cell trajectory,RNA velocity and lineage-tracing analyses revealed a putative keratinocyte-to-Paget-like cell conversion,supporting the in situ transformation theory of disease pathogenesis.Mechanistically,the Msi1-mTOR pathway drives keratinocyte-Paget-like cell conversion,and suppression of mTOR signaling with Rapamycin significantly rescued the Paget-like phenotype in Msi1-overexpressing transgenic mice.Topical Rapamycin treatment improved extramammary PD-associated symptoms in humans,suggesting mTOR inhibition as a novel therapeutic treatment in PD. | Yongli Song Christian F.Guerrero-Juarez Zhongjian Chen Yichen Tang Xianghui Ma Cong Lv Xueyun Bi Min Deng Lina Bu Yuhua Tian Ruiqi Liu Ran Zhao Jiuzhi Xu Xiaole Sheng Sujuan Du Yeqiang Liu Yunlu Zhu Shi-jun Shan Hong-duo Chen Yiqiang Zhao Guangbiao Zhou Jianwei Shuai Fazheng Ren Lixiang Xue Zhaoxia Ying Xing Dai Christopher J.Lengner Bogi Andersen Maksim V.Plikus Qing Nie Zhengquan Yu-Show | 2020 | Cell Research2020，30，10： | 2 |

| 12 | Frequency upconversion detection of rotational Doppler effect显示文摘We demonstrated an efficient scheme of measuring the angular velocity of a rotating object with the detection light working at the infrared regime.Our method benefits from the combination of second-harmonic generation(SHG)and rotational Doppler effect,i.e.,frequency upconversion detection of rotational Doppler effect.In our experiment,we use one infrared light as the fundamental wave(FW)to probe the rotating objects while preparing the other FW to carry the desired superpositions of orbital angular momentum.Then these two FWs are mixed collinearly in a potassium titanyl phosphate crystal via typeⅡphase matching,which produces the visible secondharmonic light wave.The experimental results show that both the angular velocity and geometric symmetry of rotating objects can be identified from the detected frequency-shift signals at the photon-count level.Our scheme will find potential applications in infrared monitoring. | HAOXU GUO XIAODONG QIU SONG QIU LING HONG FEI LIN YUAN REN LIXIANG CHEN | 2022 | Photonics Research2022，10，1： | 1 |

| 16 | Development of robust perovskite single crystal radiation detectors with high spectral resolution through synergetic trap deactivation and self-healing显示文摘Organic-inorganic halide perovskite single crystals(SCs)are promising materials for detecting ionizing radiation owing to their outstanding photoelectric conversion capability and inexpensive solution processability.However,the accuracy and stability of the detectors have been limited due to the charge traps and defects in SCs,especially when operated under high-precision photon-counting mode for energy spectrum acquisition.Here,we proposed a trap freezing deactivation route,which obviously suppressed dark current and noise by up to 97%and 92%,respectively.Furthermore,the bulk ion migration effect was essential for the ability to instantly self-heal defects induced by radiation damage at temperatures down to30C.Consequently,the detector exhibits a record high energy resolution of 7.5%at 59.5 keV for 241Amγ-ray source,which is the best solution-processed semiconductor radiation detectors at the same energy range.In addition,the detector maintains over 90%of its initial performance after 9 months of storage when tested in the air.Our results will represent a revision of the paradigm that high-spectral-resolution and robust radiation detectors can only be realized with high temperature grown inorganic semiconductor single crystals. | Lixiang Wang Yilong Song Liqi Li Liting Tao Minxing Yan Weihui Bi Xueying Yang Yuan Sun Qingfeng Dong Deren Yang Yanjun Fang | 2023 | InfoMat2023，5，9： | 0 |
| 17 | Study on Ability of Ground Cover Plant of Taiyuan to Adsorb PM(2.5)显示文摘Four ground cover plant species of Taiyuan( Iris,Hemerocallis,Sedum,Hosta) were selected to study their capacities in adsorbing PM_(2.5). Meanwhile,the concentration of PM_(2.5) in Taiyuan between April 2017 and August 2017 was recorded,and the characteristics of PM_(2.5) pollution in summer and autumn in Taiyuan were studied. The results showed that for the 4 plants,the ability to adsorb PM_(2.5) was in the order from great to small of Hosta,Iris,Hemerocallis,Sedum,in which H. plantaginea had the best effect to adsorb PM_(2.5). The fresh weight and dry weight per gram of H. plantaginea were 4. 4 times and 2 times higher than those of S. spectabile,while the mass quality of dust adsorption was 2.8 times higher. The sorting result was the same as the ability to adsorb PM_(2.5) of unit leaf area. The result of the coefficient of purification showed that the purification coefficients of 3 vegetation structure were positive,and the combination of trees and shrubs in university campus had strong PM_(2.5) adsorption capacity. By comparing the seasonal variation of PM_(2.5) concentration in Taiyuan city,it found that the PM_(2.5) concentration was particularly high in late spring and early summer of Taiyuan,when most of the ground cover plants were not fully grown. Therefore,ground cover plants played an important role in the construction of landscape and the regulation of ecological environment in Taiyuan. | Baochun FU Guojie QIN Ping CHANG Song WANG Min WU Lixiang ZUO Wei BO | 2018 | Agricultural Biotechnology2018，7，2： | 0 |
| 18 | Detector-grade perovskite single-crystal wafers via stress-free gel-confined solution growth targeting high-resolution ionizing radiation显示文摘Solution-processed organic‒inorganic halide perovskite(OIHP)single crystals(SCs)have demonstrated great potential in ionizing radiation detection due to their outstanding charge transport properties and low-cost preparation.However,the energy resolution(ER)and stability of OIHP detectors still lag far behind those of melt-grown inorganic perovskite and commercial CdZnTe counterparts due to the absence of detector-grade high-quality OIHP SCs.Here,we reveal that the crystallinity and uniformity of OIHP SCs are drastically improved by relieving interfacial stress with a facial gel-confined solution growth strategy,thus enabling the direct preparation of large-area detector-grade SC wafers up to 4 cm with drastically suppressed electronic and ionic defects.The resultant radiation detectors show both a small dark current below 1 nA and excellent baseline stability of 4.0×10^(-8) nA cm^(-1) s^(-1) V^(-1),which are rarely realized in OIHP detectors.Consequently,a record high ER of 4.9% at 59.5 keV is achieved under a standard 241Am gamma-ray source with an ultralow operating bias of 5 V,representing the best gamma-ray spectroscopy performance among all solution-processed semiconductor radiation detectors ever reported. | Yilong Song Lixiang Wang Yongqiang Shi Weihui Bi Jianwu Chen Mingwei Hao Anran Wang Xueying Yang Yuan Sun Fan Yu Liansheng Li Yanjun Fang Deren Yang Qingfeng Dong | 2023 | Light(Science & Applications)2023，12，5： | 0 |
| 19 | An automatically progressed computer-controlled simulated digestion system to predict digestible and metabolizable energy of unconventional plant protein meals for growing pigs显示文摘The objective of this experimentwas to develop a new computer-controlled simulated digestion system to predict the digestible energy(DE)and metabolizable energy(ME)of unconventional plant protein meals for growing pigs.Nine meals tested included 1 source of rapeseed meal,4 sources of cottonseed meal,2 sources of sunflower meal,and 2 sources of peanut meal.Twenty growing pigs(Duroc[LandraceLarge White])with an initial body weight(BW)of 41.7±2.6 kg were allotted to a replicated 103 incomplete Latin square design to determine the DE and ME of 1 basal diet and 9 experimental diets formulated with 9 unconventional plant protein meals.The DE andMEvalues of unconventional plant protein meals were calculated by the difference method.The in vitro digestible energy(IVDE)of 1 basal diet,9 experimental diets,and 9 unconventional plant protein meals were determined with 5 replicates of each sample in a complete randomized arrangement.The IVDE/DE or IVDE/ME ranged from 0.96 to 0.98 or 1.00 to 1.01,and the correlation coefficient between IVDE and DE or MEwas 0.97 or 0.98 in 10 experimental diets.Accordingly,the IVDE/DE or IVDE/ME ranged from 0.86 to 1.05 or 0.96 to 1.20,and the correlation coefficient between IVDE and DE orME was 0.92 or 0.91 in 9 unconventional plant protein meals.The coefficient of variation(CV)of IVDE was less than that of DE and ME in the experimental diets(0.43%,0.80%,and 0.97%for CV of IVDE,DE and ME,respectively)and unconventional plant protein meals(0.92%,4.84%,and 6.33%for CV of IVDE,DE and ME,respectively).The regression equations to predict DE from IVDE in 10 experimental diets and 9 unconventional plant protein meals were DE=0.8851IVDE t539(R^(2)=0.9411,residual standard deviation[RSD]=23 kcal/kg DM,P<0.01)and DE=0.9880IVDE t 166(R^(2)=0.8428,RSD=182 kcal/kg DM,P<0.01),respectively.Therewas no statistical difference in the slopes(P=0.82)or intercepts(P=1.00)of these 2 equations.Thus,10 diets and 9 unconventional plant protein meals were pooled to establish the regression equation of DE on IVDE as:DE=0.9813IVDE t187(R^(2)=0.9120,RSD=118 kcal/kg DM,P<0.01).The regression equations to predictME from IVDE in 10 experimental diets and 9 unconventional plant protein meals were ME=0.9559IVDE t146(R^(2)=0.9697,RSD=18 kcal/kg DM,P<0.01)and ME=0.9388IVDEt3(R^(2)=0.8282,RSD=182 kcal/kg DM,P<0.01),respectively.Therewas no statistical difference in slopes(P=0.97)but significant difference between the intercepts(P=0.02)of these 2 equations.Our results indicate IVDE has similar response to the DE but different response to the ME in 10 experimental diets and 9 unconventional plant protein meals.Therefore,IVDE is moresuitable to predict DE than ME of diets and unconventional plant protein meals for growing pigs. | Zhongyuan Du Yuming Wang Mingqiang Song Shuli Zeng Lixiang Gao Jiangtao Zhao Feng Zhao | 2022 | Animal Nutrition2022，，3： | 0 |
