| 1 | Recent temperature increase recorded in an ice core in the source region of Yangtze River显示文摘Interests on climate change in the source region of Yangtze River have been raised since it is a region with the greatest warming over the Tibetan Plateau (TP). A 70-year history of precipitation δ^(18)O has been recovered using an ice core record retrieved in a plat portion of the firn area in the Guoqu Glacier (33°34′37.8″N, 91°10′35.3″E, 5720 m a.s.l.), Mt. Geladaindong (the source region of Yangtze River), in November, 2005. By using a significant positive relationship between ice core δ^(18)O record and summer air temperature (July to September) from the nearby meteorological stations, a history of summer air temperature has been reconstructed for the last 70 years. Summer temperature was relatively low in 1940s and high in 1950s to the middle of 1960s. The lowest temperature occurred in the middle of 1970s. Temperature was low in 1980s and dramatically increased since 1990s, keeping the trend to the begin-ning of the 21st century. The warming rate recorded in the ice core with 0.5℃/10 a since 1970s is much higher that that in the central TP and the Northern Hemisphere (NH), and it becomes 1.1℃/10 a since 1990s which is also higher than these from the central TP and the NH, reflecting an accelerated warm-ing and a more sensitive response to global warming in the high elevation region. | KANG ShiChang ZHANG YongJun QIN DaHe REN JiaWen ZHANG QiangGong Bjorn GRIGHOLM Paul A.

| 2 | Three-dimensional chiral microstructures fabricated by structured optical vortices in isotropic material显示文摘Optical vortices,a type of structured beam with helical phase wavefronts and‘doughnut’-shaped intensity distributions,have been used to fabricate chiral structures in metals and spiral patterns in anisotropic polarization-dependent azobenzene polymers.However,in isotropic polymers,the fabricated microstructures are typically confined to non-chiral cylindrical geometry due to the two-dimensional‘doughnut’-shaped intensity profile of the optical vortices.Here we develop a powerful strategy to realize chiral microstructures in isotropic material by coaxial interference of a vortex beam and a plane wave,which produces threedimensional(3D)spiral optical fields.These coaxial interference beams are generated by designing contrivable holograms consisting of an azimuthal phase and an equiphase loaded on a liquid-crystal spatial light modulator.In isotropic polymers,3D chiral microstructures are achieved under illumination using coaxial interference femtosecond laser beams with their chirality controlled by the topological charge.Our further investigation reveals that the spiral lobes and chirality are caused by interfering patterns and helical phase wavefronts,respectively.This technique is simple,stable and easy to perform,and it offers broad applications in optical tweezers,optical communications and fast metamaterial fabrication. | Jincheng Ni Chaowei Wang Chenchu Zhang Yanlei Hu Liang Yang Zhaoxin Lao Bing Xu Jiawen Li Dong Wu Jiaru Chu | 2017 | Light(Science & Applications)2017，6，1： | 28 |
| 3 | First mass measurement of short-lived nuclides at HIRFL-CSR显示文摘Recent commissioning of the HIRFL-CSR has demonstrated its ability to perform direct mass measurement for short-lived nuclides. Projectile fragments produced by the 78Kr ions at 481.88 MeV/u were separated with the new radioactive beam line in Lanzhou (RIBLL2), and injected into and stored in the experimental storage ring (CSRe). By operating the CSRe as an isochronous mass spectrometry, a typical mass resolution around 2.0×10?5 has been achieved. The masses for 63Ge, 65As and 67Se were measured for the first time. The measured masses are compared with theoretical predictions and the location of the proton drip-line for As isotopes is discussed. The implication of the 65As mass in the astrophysical rapid proton capture process has also been addressed. | XU HuShan TU XiaoLin YUAN YouJin XIA JiaWen ZANG YongDong WANG Meng MAO RuiShi HU ZhengGuo MEI Bo SHUAI Peng ZHU ZhiChao TANG ShuWen GENG Peng LIU Yong ZHAO TieCheng ZHANG XueYing YANG JianCheng MAO LiJun ZHANG YuHu ZHOU XiaoHong HUANG WenXue XIAO GuoQing ZHAO HongWei ZHAN WenLong | 2009 | Chinese Science Bulletin2009，54，24： | 11 |

| 6 | HRRP target recognition based on kernel joint discriminant analysis显示文摘With the improvement of radar resolution,the dimension of the high resolution range profile(HRRP)has increased.In order to solve the small sample problem caused by the increase of HRRP dimension,an algorithm based on kernel joint discriminant analysis(KJDA)is proposed.Compared with the traditional feature extraction methods,KJDA possesses stronger discriminative ability in the kernel feature space.K-nearest neighbor(KNN)and kernel support vector machine(KSVM)are applied as feature classifiers to verify the classification effect.Experimental results on the measured aircraft datasets show that KJDA can reduce the dimensionality,and improve target recognition performance. | LIU Wenbo YUAN Jiawen ZHANG Gong SHEN Qian | 2019 | Journal of Systems Engineering and Electronics2019，30，4： | 7 |
| 7 | BAALC-AS1/G3BP2/c-Myc feedback loop promotes cell proliferation in esophageal squamous cell carcinoma显示文摘Background:Long non-codingRNAs(lncRNAs)have been found to be involved in the development of many cancers.In this study,we aimed to identify the molecular mechanisms of lncRNA BAALC antisense RNA 1(BAALC-AS1)in regulating the malignancy of esophageal squamous cell carcinoma(ESCC).Methods:The expression of BAALC-AS1 in cancer patients was analyzed using a tissue microarray.The protein and RNA levels of BAALC-AS1 were determined by Western blotting analysis and quantitative reverse transcription-PCR(RT-qPCR),respectively.The cell proliferation was determined by cell viability assays,bromodeoxyuridine incorporation,and flow cytometry.The relationships among BAALC-AS1,RasGAPSH3 domain-binding protein 2(G3BP2),and c-Myc were determined using RNA immunoprecipitation,RNA pull-down assays,and luciferase assays.Results:The expression of BAALC-AS1 was highly up-regulated and associated with malignant phenotypes in ESCC tissues and cell lines.In vivo and in vitro assays showed that BAALC-AS1 promoted ESCC cell proliferation,migration,and invasion.BAALC-AS1 directly interacted with G3BP2,and thereby inhibited the degradation of c-Myc RNA 3’-UTR by G3BP2,thus leading to the accumulation of c-Myc expression.Additionally,c-Myc acted as a transcription factor that can induce the expression of BAALC-AS1 by directly binding to its promoter region.Conclusions:BAALC-AS1/G3BP2/c-Myc feedback loop plays a critical role in the development of ESCC,which might provide a novel therapeutic target and facilitate the development of new therapeutic strategies for the treatment of ESCC. | Hongyue Zhang Yan Wang Weimin Zhang Qingnan Wu Jiawen Fan Qimin Zhan | 2021 | Cancer Communications2021，41，3： | 7 |
| 8 | Simultaneous quantification of ginsenoside Rg1 and its metabolites by HPLC–MS/MS:Rg1 excretion in rat bile, urine and feces显示文摘Ginsenoside Rg1(Rg1), the major effective component of ginseng, has been shown to have multiple bioactivities, but low oral bioavailability. The aim of this study was to develop a simple, sensitive and rapid high performance liquid chromatography–tandem mass spectrometry(LC–MS/MS) method, which could be used to validate and quantify the concentrations of Rg1 and its metabolites in Sprague-Dawley rat bile,urine, and feces after oral administration(25 mg/kg). Calibration curves offered satisfactory linearity(r40.995)within the determined ranges. Both intra-day and inter-day variances were less than 15%, and the accuracy was within 80–120%. The excretion recoveries of Rg1, ginsenoside Rh1(Rh1), and protopanaxatriol(Ppt) in bile,urine, and feces combined were all greater than 70%. The fecal excretion recoveries of Rg1, Rh1, and Ppt were40.11%, 22.19%, and 22.88%, respectively, whereas 6.88% of Rg1 and 0.09% of Rh1 were excreted in bile.Urinary excretion accounted for only 0.04% of Rg1. In conclusion, the observed excretion profiles for Rg1 and its metabolites after oral administration are helpful for understanding the poor oral bioavailability of Rg1 and will aid further investigations of Rg1 as a pharmacologically active component. | Chiyu He Ru Feng Yupeng Sun Shifeng Chu Ji Chen Chao Ma Jie Fu Zhenxiong Zhao Min Huang Jiawen Shou Xiaoyang Li Yuzhu Wang Jinfeng Hu Yan Wang Juntian Zhang | 2016 | Acta Pharmaceutica Sinica B2016，6，6： | 6 |
| 9 | Evaluation of the New Dynamic Global Vegetation Model in CAS-ESM显示文摘In the past several decades, dynamic global vegetation models(DGVMs) have been the most widely used and appropriate tool at the global scale to investigate vegetation-climate interactions. At the Institute of Atmospheric Physics, a new version of DGVM(IAP-DGVM) has been developed and coupled to the Common Land Model(CoLM) within the framework of the Chinese Academy of Sciences' Earth System Model(CAS-ESM). This work reports the performance of IAP-DGVM through comparisons with that of the default DGVM of CoLM(CoLM-DGVM) and observations. With respect to CoLMDGVM, IAP-DGVM simulated fewer tropical trees, more 'needleleaf evergreen boreal tree' and 'broadleaf deciduous boreal shrub', and a better representation of grasses. These contributed to a more realistic vegetation distribution in IAP-DGVM,including spatial patterns, total areas, and compositions. Moreover, IAP-DGVM also produced more accurate carbon fluxes than CoLM-DGVM when compared with observational estimates. Gross primary productivity and net primary production in IAP-DGVM were in better agreement with observations than those of CoLM-DGVM, and the tropical pattern of fire carbon emissions in IAP-DGVM was much more consistent with the observation than that in CoLM-DGVM. The leaf area index simulated by IAP-DGVM was closer to the observation than that of CoLM-DGVM; however, both simulated values about twice as large as in the observation. This evaluation provides valuable information for the application of CAS-ESM, as well as for other model communities in terms of a comparative benchmark. | Jiawen ZHU Xiaodong ZENG Minghua ZHANG Yongjiu DAI Duoying JI Fang LI Qian ZHANG He ZHANG Xiang SONG | 2018 | Advances in Atmospheric Sciences2018，35，6： | 6 |
| 10 | Energy-Efficient Mapping for 3D NoC Using Logistic Function Based Adaptive Genetic Algorithms显示文摘The problem of mapping application tasks is one of key issues in 3D Network on chip(3D NoC) design. A novel Logistic function based adaptive genetic algorithm(LFAGA) is proposed for energy-aware mapping of homogeneous 3D NoC. We formulate the mapping problem and show the Standard genetic algorithm(SGA). The LFAGA is presented in detail with the goal of obtaining higher convergence speed while preventing the premature convergence. Experimental results indicate that the proposed LFAGA is more efficient than previously proposed Chaos-genetic mapping algorithm(CGMAP). In the experiments, a randomly generated task graph of size 27 is mapped to a 3D NoC of size 3×3×3, the convergence speed of LFAGA is 2.55 times faster than CGMAP in the best condition. When the task size increases to 64 and the 3D NoC size extends to 4×4×4, LFAGA is 2.31 times faster compared to CGMAP. For the No C sizes in the range from 3×3×2 to 4×4×4, solutions obtained by the LFAGA are consistently better than the CGMAP. For example, in the experiment of size 4×4×4, the improvement of final result reaches 30.0% in term of energy consumption. For a real application of size 3×4×2, 18.6% of energy saving can be achieved and the convergence speed is 1.58 times faster than that of the CGMAP. | WANG Jiawen LI Li WANG Zhongfeng ZHANG Rong ZHANG Yuang | 2014 | Chinese Journal of Electronics2014，23，2： | 5 |
| 11 | Quasi-phase-matching-division multiplexing holography in a three-dimensional nonlinear photonic crystal显示文摘Nonlinear holography has recently emerged as a novel tool to reconstruct the encoded information at a new wavelength,which has important applications in optical display and optical encryption.However,this scheme still struggles with low conversion efficiency and ineffective multiplexing.In this work,we demonstrate a quasi-phasematching(QPM)-division multiplexing holography in a three-dimensional(3D)nonlinear photonic crystal(NPC).3D NPC works as a nonlinear hologram,in which multiple images are distributed into different Ewald spheres in reciprocal space.The reciprocal vectors locating in a given Ewald sphere are capable of fulfilling the complete QPM conditions for the high-efficiency reconstruction of the target image at the second-harmonic(SH)wave.One can easily switch the reconstructed SH images by changing the QPM condition.The multiplexing capacity is scalable with the period number of 3D NPC.Our work provides a promising strategy to achieve highly efficient nonlinear multiplexing holography for high-security and high-density storage of optical information. | Pengcheng Chen Chaowei Wang Dunzhao Wei Yanlei Hu Xiaoyi Xu Jiawen Li Dong Wu Jianan Ma Shengyun Ji Leran Zhang Liqun Xu Tianxin Wang Chuan Xu Jiaru Chu Shining Zhu Min Xiao Yong Zhang | 2021 | Light(Science & Applications)2021，10，8： | 5 |
| 12 | Mapping and analysis of a spatiotemporal H3K27ac and gene expression spectrum in pigs显示文摘The limited knowledge of genomic noncoding and regulatory regions has restricted our ability to decipher the genetic mechanisms underlying complex traits in pigs. In this study, we characterized the spatiotemporal landscape of putative enhancers and promoters and their target genes by combining H3K27ac-targeted Ch IP-Seq and RNA-Seq in fetal(prenatal days 74–75) and adult(postnatal days 132–150) tissues(brain, liver, heart, muscle and small intestine) sampled from Asian aboriginal Bama Xiang and European highly selected Large White pigs of both sexes. We identified 101,290 H3K27ac peaks, marking 18,521promoters and 82,769 enhancers, including peaks that were active across all tissues and developmental stages(which could indicate safe harbor locus for exogenous gene insertion) and tissue-and developmental stage-specific peaks(which regulate gene pathways matching tissue-and developmental stage-specific physiological functions). We found that H3K27ac and DNA methylation in the promoter region of the XIST gene may be involved in X chromosome inactivation and demonstrated the utility of the present resource for revealing the regulatory patterns of known causal genes and prioritizing candidate causal variants for complex traits in pigs. In addition, we identified an average of 1,124 super-enhancers per sample and found that they were more likely to show tissue-specific activity than ordinary peaks. We have developed a web browser to improve the accessibility of the results(http://segtp.jxau.edu.cn/pencode/?genome=sus Scr11). | Yaling Zhu Zhimin Zhou Tao Huang Zhen Zhang Wanbo Li Ziqi Ling Tao Jiang Jiawen Yang Siyu Yang Yanyuan Xiao Carole Charlier Michel Georges Bin Yang Lusheng Huang | 2022 | Science China(Life Sciences)2022，65，8： | 5 |
| 13 | Epigallocatechin-3-gallate inhibits angiotensin Il-induced cardiomyocyte hypertrophy via regulating Hippo signaling pathway in H9c2 rat cardiomyocytes显示文摘AngiotensinⅡ(All) has been well known to induce cardiomyocyte hypertrophy. Epigallocatechin-3-gallate (EGCG) is the main active comp on ent of green tea and it has bee n show n to exhibit strong cardioprotective potential, although the underlying molecular mechanisms remain unclear. In this study, we investigated the role and mechanism of EGCG in preventing All-induced cardiomyocyte hypertrophy using rat H9c2 cardiomyocytes cells. Reactive oxygen species assay, cell size, and mRNA expression of cardiac hypertrophy markers ANP and BNP were assessed in response to All treatment. In addition, expression of proteins involved in Hippo signaling pathway were determined by western blot analysis. We found that All treatment resulted in significant upregulation of ANP and BNP expression levels and increase in H9c2 cell size, which were markedly attenuated by EGCG treatment. Furthermore, our results suggested that EGCG inhibited Allinduced cardiac hypertrophy via regulating the Hippo signaling pathway. Therefore, EGCG may be an effective agent for preventing cardiac hypertrophy. | Yuan Ma Yongjia Hu Jiawen Wu Junru Wen Sen Li Lijuan Zhang Jie Zhang Yanfei Jue Li | 2019 | Acta Biochimica et Biophysica Sinica2019，51，4： | 4 |
| 14 | Growth and metal uptake of energy sugarcane (Saccharum spp.) in different metal mine tailings with soil amendments显示文摘A pot experiment was conducted to investigate the feasibility of growing energy sugarcane(Saccharum spp.) in three different metal mine tailings(Cu, Sn and Pb/Zn tailings) amended with uncontaminated soil at different mixing ratios. The results indicated that sugarcane was highly tolerant to tailing environments. Amendments of 20% soil to Sn tailings and 30% soil to Cu tailings could increase the biomass of cane-stem for use as the raw material for bioethanol production. Heavy metals were mostly retained in roots, which indicated that sugarcane was useful for the stabilization of the tailings. Bagasse and juice, as the most valuable parts to produce bioethanol, only accounted for 0.6%– 3% and 0.6%–7% of the total metal content. Our study supported the potential use of sugarcane for tailing phytostabilization and bioenergy production. | Xin Zhang Yongguan Zhu Yuebin Zhang Yunxia Liu Shaochun Liu Jiawen Guo Rudan Li Songlin Wu Baodong Chen | 2014 | Journal of Environmental Sciences2014，26，5： | 4 |
| 15 | Efficient full-path optical calculation of scalar and vector diffraction using the Bluestein method显示文摘Efficient calculation of the light diffraction in free space is of great significance for tracing electromagnetic field propagation and predicting the performance of optical systems such as microscopy,photolithography,and manipulation.However,existing calculation methods suffer from low computational efficiency and poor flexibility.Here,we present a fast and flexible calculation method for computing scalar and vector diffraction in the corresponding optical regimes using the Bluestein method.The computation time can be substantially reduced to the sub-second level,which is 105 faster than that achieved by the direct integration approach(~hours level)and 102 faster than that achieved by the fast Fourier transform method(~minutes level).The high efficiency facilitates the ultrafast evaluation of light propagation in diverse optical systems.Furthermore,the region of interest and the sampling numbers can be arbitrarily chosen,endowing the proposed method with superior flexibility.Based on these results,full-path calculation of a complex optical system is readily demonstrated and verified by experimental results,laying a foundation for real-time light field analysis for realistic optical implementation such as imaging,laser processing,and optical manipulation. | Yanlei Hu Zhongyu Wang Xuewen Wang Shengyun Ji Chenchu Zhang Jiawen Li Wulin Zhu Dong Wu Jiaru Chu | 2020 | Light(Science & Applications)2020，9，1： | 4 |
| 16 | Ultralight Magnetic and Dielectric Aerogels Achieved by Metal-Organic Framework Initiated Gelation of Graphene Oxide for Enhanced Microwave Absorption显示文摘The development of a convenient methodology for synthesizing the hierarchically porous aerogels comprising metal–organic frameworks(MOFs)and graphene oxide(GO)building blocks that exhibit an ultralow density and uniformly distributed MOFs on GO sheets is important for various applications.Herein,we report a facile route for synthesizing MOF/reduced GO(rGO)aerogels based on the gelation of GO,which is directly initiated using MOF crystals.Free metal ions exposed on the surface of MIL-88A nanorods act as linkers that bind GO nanosheets to a three-dimensional porous network via metal–oxygen covalent or electrostatic interactions.The MOF/rGOderived magnetic and dielectric aerogels Fe_(3)O_(4)@C/rGO and Ni-doped Fe_(3)O_(4)@C/rGO show notable microwave absorption(MA)performance,simultaneously achieving strong absorption and broad bandwidth at low thickness of 2.5(-58.1 dB and 6.48 GHz)and 2.8 mm(-46.2 dB and 7.92 GHz)with ultralow filling contents of 0.7 and 0.6 wt%,respectively.The microwave attenuation ability of the prepared aerogels is further confirmed via a radar cross-sectional simulation,which is attributed to the synergistic effects of their hierarchically porous structures and heterointerface engineering.This work provides an effective pathway for fabricating hierarchically porous MOF/rGO hybrid aerogels and offers magnetic and dielectric aerogels for ultralight MA. | Xiaogu Huang Jiawen Wei Yunke Zhang BinBin Qian Qi Jia Jun Liu Xiaojia Zhao Gaofeng Shao | 2022 | Nano-Micro Letters2022，14，7： | 4 |
| 17 | Classification of Imagined Speech EEG Signals with DWT and SVM显示文摘With the development of human-computer interaction technology,brain-computer interface(BCI)has been widely used in medical,entertainment,military,and other fields.Imagined speech is the latest paradigm of BCI and represents the mental process of imagining a word without making a sound or making clear facial movements.Imagined speech allows patients with physical disabilities to communicate with the outside world and use smart devices through imagination.Imagined speech can meet the needs of more complex manipulative tasks considering its more intuitive features.This study proposes a classification method of imagined speech Electroencephalogram(EEG)signals with discrete wavelet transform(DWT)and support vector machine(SVM).An open dataset that consists of 15 subjects imagining speaking six different words,namely,up,down,left,right,backward,and forward,is used.The objective is to improve the classification accuracy of imagined speech BCI system.The features of EEG signals are first extracted by DWT,and the imagined words are clas-sified by SVM with the above features.Experimental results show that the proposed method achieves an average accuracy of 61.69%,which is better than those of existing methods for classifying imagined speech tasks. | ZHANG Lingwei ZHOU Zhengdong XU Yunfei JI Wentao WANG Jiawen SONG Zefeng | 2022 | Instrumentation2022，9，2： | 4 |

| 20 | Intermolecular and Surface Interactions in Engineering Processes显示文摘Interactions involving chemical reagents,solid particles,gas bubbles,liquid droplets,and solid surfaces in complex fluids play a vital role in many engineering processes,such as froth flotation,emulsion and foam formation,adsorption,and fouling and anti-fouling phenomena.These interactions at the molecular,nano-,and micro scale significantly influence and determine the macroscopic performance and efficiency of related engineering processes.Understanding the intermolecular and surface interactions in engineering processes is of both fundamental and practical importance,which not only improves production technologies,but also provides valuable insights into the development of new materials.In this review,the typical intermolecular and surface interactions involved in various engineering processes,including Derjaguin–Landau–Verwey–Overbeek(DLVO)interactions(i.e.,van der Waals and electrical doublelayer interactions)and non-DLVO interactions,such as steric and hydrophobic interactions,are first introduced.Nanomechanical techniques such as atomic force microscopy and surface forces apparatus for quantifying the interaction forces of molecules and surfaces in complex fluids are briefly introduced.Our recent progress on characterizing the intermolecular and surface interactions in several engineering systems are reviewed,including mineral flotation,petroleum engineering,wastewater treatment,and energy storage materials.The correlation of these fundamental interaction mechanisms with practical applications in resolving engineering challenges and the perspectives of the research field have also been discussed. | Jiawen Zhang Hongbo Zeng | 2021 | Engineering2021，7，1： | 3 |
