| 1 | New Zircon U-Pb Age of the Super-Large Lijiagou Spodumene Deposit in Songpan Garze Fold Belt, Eastern Tibet: Implications for Early Jurassic Rare-Metal Polymetallic Event显示文摘The Songpan-Garze Fold Belt (SGFB), located in theeastern part of the Tibet Plateau and west of the SichuanBasin, is an important pegmatite province in China. Somefamous pegmatite type deposits occur in the SGFB,including the Xuebaoding, Jiajika, Keeryin rare metaldeposits and Danba muscovite deposit (Li Jiankang et al.,2015). | FEI Guangchun TIAN Jingjing YANG Jiyi GAO Jianguo TANG Wenchun LI Jian GU Chenghui | 2018 | Acta Geologica Sinica(English Edition)2018，92，3： | 5 |
| 2 | Lithium-bearing Pegmatite Exploration in Western Altun,Xinjiang,using Remote-Sensing Technology显示文摘Western Altun in Xinjiang is an important area,where lithium(Li)-bearing pegmatites have been found in recent years.However,the complex terrain and harsh environment of western Altun exacerbates in prospecting for Li-bearing pegmatites.Therefore,remote-sensing techniques can be an effective means for prospecting Li-bearing pegmatites.In this study,the fault information and lithologyical information in the region were obtained using the median-resolution remotesensing image Landsat-8,the radar image Sentinel-1 and hyperspectral data GF-5.Using Landsat-8 data,the hydroxyl alteration information closely related to pegmatite in the region was extracted by principal component analysis,pseudoanomaly processing and other methods.The high spatial resolution remote-sensing data WorldView-2 and WorldView-3 short-wave infrared images were used and analyzed by principal component analysis(PCA),the band ratio method and multi-class machine learning(ML),combined with conventional thresholds specified the algorithms used to automatically extract Li-bearing pegmatite information.Finally,the Li-bearing pegmatite exploration area was determined,based on a comprehensive analysis of the faults,hydroxyl alteration lithology and Li-bearing pegmatite information.Field investigations have verified that the distribution of pegmatites in the central part of the study area is consistent with that of Li-bearing pegmatites extracted in this study.This study provides a new technique for prospecting Li-bearing pegmatites,which shows that remote-sensing technology possesses great potential for identifying lithium-bearing pegmatites,especially in areas that are not readily accessible. | JIANG Qi DAI Jingjing WANG Denghong WANG Chenghui TIAN Shufang | 2023 | Acta Geologica Sinica(English Edition)2023，97，2： | 2 |

| 4 | Fiber laser for on-demand mode generation in 1550 nm band显示文摘Transverse mode characteristics of a laser are related to a variety of interesting applications. An on-demand mode solid laser in the 1064 nm band was proposed previously. In this paper, we provide a fiber laser for on-demand modes in the 1550 nm band to prescribe the pure and high-quality emission of a higher-order transverse laser mode, based on a simple construction with one spatial light modulator(SLM) and a single-mode erbium-doped fiber(SM-EDF). The SLM is designated to generate the desired higher-order mode and separate the higher-order mode and the fundamental mode. The fundamental mode oscillates in the fiber ring laser, and therefore the SM-EDF can be pumped with a single-mode 980 nm laser, no matter what higher-order mode is prescribed.In this proof-of-principle experiment, high-quality higher-order modes are observed from LP01 to LP105.Stable emission and real-time switching between modes can be easily realized by altering the phase on the SLM. In addition, the propagation of the LP_(01), LP_(11), LP_(21), and LP_(02) modes from the fiber laser is also demonstrated in a four-mode few-mode fiber. | CHENGHUI TIAN SONG YU SHANYONG CAI MINGYING LAN WANYI GU | 2017 | Photonics Research2017，5，3： | 1 |
| 5 | Equilibrium electron beam parameters of the High Energy Photon Source显示文摘Purpose The physics design of the High Energy Photon Source(HEPS)was finished after many times of iteration.Hereby,the typical equilibrium electron beam parameters corresponding to the proposed two baseline operation modes in the baseline design of HEPS are presented.Methods To compute the equilibrium parameters of the electron beam,the lattice parameters,RF parameters,and the parameters of the insertion devices(IDs)were determined first.Furthermore,it is more precise to use the full-current electron beam parameters in the estimations of the performance of the synchrotron light.Therefore,not only the single-particle dynamics but also the current-dependent collective effects need to be considered in the computations of the full-current,equilibrium parameters of the electron beam.Both analytic computations and multi-particle tracking simulations were carried out.Results The full-current,equilibrium parameters of the electron beams in the HEPS storage ring are presented in this paper.Moreover,the main beam parameters in the injector(the booster and the LINAC),corresponding to the two baseline operation modes of the storage ring,are also presented.Conclusion The typical electron beam parameters corresponding to the two baseline operation modes are given in detail in this paper. | Haisheng Xu Cai Meng Yuemei Peng Saike Tian Na Wang Xiaohao Cui Chongchong Du Zhe Duan Yuanyuan Guo Ping He Xiyang Huang Daheng Ji Hongfei Ji Yi Jiao Jingyi Li Nan Li Xiaoyu Li Xiaohan Lu Pengfei Liang Weimin Pan Huamin Qu Bin Wang Jiuqing Wang Yuanyuan Wei Jinyu Wan Gang Xu Fang Yan Chenghui Yu Sen Yue Xiang Zhang Yaliang Zhao | 2023 | Radiation Detection Technology and Methods2023，7，2： | 0 |
| 6 | State feedback stabilization for high-order stochastic nonlinear systems with zero dynamics显示文摘In this paper, for a class of high-order stochastic nonlinear systems with zero dynamics which are neither necessarily feedback linearizable nor af?ne in the control input, the problem of state feedback stabilization is investigated for the ?rst time. Under some weaker assumptions, a smooth state feedback controller is designed, which ensures that the closed-loop system has an almost surely unique solution on [0, ∞), the equilibrium at the origin of the closed-loop system is globally asymptotically stable in probability, and all the states can be regulated to the origin almost surely. A simulation example demonstrates the control scheme. | Jie TIAN Xuejun XIE Chenghui ZHANG | 2008 | 控制理论与应用(英文版)2008，6，1： | 0 |
| 7 | A novel function of CREG in metabolic disorders显示文摘Metabolic disorders are public health problems that require prevention and new efficient drugs for treatment.Cellular repressor of E1A-stimulated genes(CREG)is ubiquitously expressed in mature tissues and cells in mammals and plays a critical role in keeping cells or tissues in a mature,homeostatic state.Recently,CREG turns to be an important mediator in the development of metabolic disorders.Here in this review,we briefly discuss the structure and molecular regulation of CREG along with the therapeutic strategy to combat the metabolic disorders. | Yang Li Xiaoxiang Tian Quanyu Zhang Chenghui Yan Yaling Han | 2021 | Medical Review2021，1，1： | 0 |
| 8 | Highly specific quantification of mRNA mutation in single cells based on RNase H cleavage-assisted reverse transcription(RT)-PCR显示文摘Accurate quantitation of site-specific mRNA mutation in single cells or in peripheral blood is of great significance for both biological and biomedical studies.How to eliminate the false-positive interference from the abundant normal mRNA is still a big challenge.Herein,we have proposed an LNA(locked nucleic acid)-assisted high-specificity strategy which can selectively guide the RNase H to cleave only the wildtype mRNA(wtRNA)while the mutant mRNA(mutRNA)will remain intact.The intact mutRNA can be amplified and detected by real-time reverse transcription(RT)-PCR but the disconnected wtRNA will be not replicated at all.Based on the highly selective depletion of wtRNA,this elegant design effectively avoids the false-positive interference from the high background of normal mRNA and thus can guarantee the accurate and reliable detection of rare mutRNA in real biomedical samples.Besides for the excellent specificity,ultrahigh sensitivity is also achieved for this proposed assay,which allows the quantification of mutRNA at single molecule and single cell level.Due to its easy design,high sensitivity and specificity,the established LNA probe-assisted RT-PCR strategy provides a powerful tool for studying the function of mutRNA at the single cell level and for the mutRNA-associated liquid biopsy. | Dandan Yang Yuanyuan Sun Fu Chang Hui Tian Chenghui Liu Zhengping Li | 2020 | Chinese Chemical Letters2020，31，5： | 0 |
