| 1 | THEORY OF DIELECTRIC ELASTOMERS显示文摘In response to a stimulus,a soft material deforms,and the deformation provides a function.We call such a material a soft active material (SAM).This review focuses on one class of soft active materials: dielectric elastomers.When a membrane of a dielectric elastomer is subject to a voltage through its thickness,the membrane reduces thickness and expands area,possibly straining over 100%.The dielectric elastomers are being developed as transducers for broad applications,including soft robots,adaptive optics,Braille displays,and electric generators.This paper reviews the theory of dielectric elastomers,developed within continuum mechanics and thermodynamics,and motivated by molecular pictures and empirical observations.The the-ory couples large deformation and electric potential,and describes nonlinear and nonequilibrium behavior,such as electromechanical instability and viscoelasticity.The theory enables the finite element method to simulate transducers of realistic configurations,predicts the efficiency of elec-tromechanical energy conversion,and suggests alternative routes to achieve giant voltage-induced deformation.It is hoped that the theory will aid in the creation of materials and devices. | Zhigang Suo (School of Engineering and Applied Sciences,Kavli Institute for Nanobio Science and Technology,Harvard University,Cambridge,MA 02138,USA) | 2010 | Acta Mechanica Solida Sinica2010，23，6： | 37 |
| 2 | Differential expression of serum miR-126,miR-141 and miR-21 as novel biomarkers for early detection of liver metastasis in colorectal cancer显示文摘Objective:MicroRNAs(miRNAs) have potential as diagnostic biomarkers in cancer.Evaluation of the association between miRNA expression patterns and early detection of liver metastasis in colorectal cancer(CRC) has not been reported.Methods:We investigated the expression of metastasis-associated miRs-31,335,206,141,126,200b,200c,21,Let7a,Let7b and Let7c in localized,liver-metastatic and other organ-metastatic CRC(OM-CRC).Expressions of target miRNAs in serum were evaluated in 116 consecutive localized CRC(L-CRC),72 synchronous liver-metastatic CRC(SLM-CRC) and 36 other OM-CRC by quantitative real-time PCR.Results:Seven of 11 tested miRNAs could be detected from serum.Four miRNAs,miR-126,Let-7a,miR-141 and miR-21 were identified as metastasis-associated miRNAs.Compared with L-CRC,significant upregulated expression was observed for miR-141 and miR-21 in SLM-CRC and OM-CRC,down-regulated expression was observed for miR-126 in SLM-CRC and OM-CRC,and up-regulated expression of Let-7a in OM-CRC.The receiver operating characteristic(ROC) curve showed serum miR-126 had a cut-off [log 10 relative quantity(log 10 RQ)=–0.2005] with 77.78% sensitivity and 68.97% specificity with an area under curve(AUC) of 0.7564,miR-141 had a cut-off(log 10 RQ=–0.2285) with 86.11% sensitivity and 76.11% specificity with an AUC of 0.8279,and miR-21 had a cut-off(log 10 RQ=–0.1310) with 73.61% sensitivity and 66.38% specificity with an AUC of 0.7479.Conclusions:We identified liver metastasis-associated miRNAs,suggesting serum miR-126,miR-141 and miR-21 may be novel biomarkers for clinical diagnosis of early stage liver-metastatic CRC. | Jie Yin Zhigang Bai Jianning Song Yun Yang Jin Wang Wei Han Jun Zhang Hua Meng Xuemei Ma Yao Yang Tingting Wang Weirong Li Zhongtao Zhang | 2014 | Chinese Journal of Cancer Research2014，26，1： | 22 |

| 5 | Effect of Reclamation Time and Land Use on Soil Properties in Changjiang River Estuary,China显示文摘The objective of this study is to analyze soil physical and chemical properties,soil comprehensive functions and impact factors after different years of reclamation.Based on the survey data taken from 216 soil sampling points in the Fengxian Reclamation Area of the Changjiang (Yangtze) River Estuary,China in April 2009 and remotely sensed TM data in 2006,while by virtue of multivariate analysis of variance (MANOVA),geo-statistical analysis (GA),prin-cipal component analysis (PCA) and canonical correspondence analysis (CCA),it was concluded that:1) With the in-crease in reclamation time,soil moisture,soil salinity,soil electric conductivity and soil particle size tended to decline,yet soil organic matter tended to increase.Soil available phosphorous tended to increase in the early reclamation period,yet it tended to decline after about 49 years of reclamation.Soil nitrate nitrogen,soil ammonia nitrogen and pH changed slightly in different reclamation years.Soil physical and chemical properties reached a steady state after about 30 years of reclamation.2) According to the results of PCA analysis,the weighted value (0.97 in total) that represents soil nutrient factors (soil nitrate nitrogen,soil organic matter,soil available phosphorous,soil ammonia nitrogen,pH and soil particle size) were higher than the weighted value (0.48 in total) of soil limiting factors (soil salinity,soil elec-tric conductivity and soil moisture).The higher the F value is,the better the soil quality is.3) Different land use types play different roles in the soil function maturity process,with farmlands providing the best contribution.4) Soil physi-cal and chemical properties in the reclamation area were mainly influenced by reclamation time,and then by land use types.The correlation (0.1905) of the composite index of soil function (F) with reclamation time was greater than that with land use types (-0.1161). | SUN Yongguang LI Xiuzhen ülo MANDER HE Yanlong JIA Yue MA Zhigang GUO Wenyong XIN Zaijun | 2011 | Chinese Geographical Science2011，21，4： | 17 |
| 6 | Control of nonmetallic inclusions of non-oriented silicon steel sheets by the rare earth treatment显示文摘Based on the industrial production of non-oriented silicon steel,the rare earth(RE) treatment during the Ruhrstahl Heraeus(RH) refining process was studied.The morphology and the size distribution were observed for the steel specimens treated with different RE treatment conditions.Furthermore,the formation and change of the nonmetallic inclusion characteristics of finished steel sheets after the RE treatment were discussed.The results have shown that in the present work,the suitable RE metal additions are 0.6-0.9 kg/t steel.After the suitable RE treatment,the formation of AlN and MnS inclusions were restrained,and the aggregation,flotation and removal of nonmetallic inclusions were efficiently promoted and the cleanliness of liquid steel was significantly increased.Meanwhile,the total oxygen concentration reached the minimum value and the desulfurization efficiency was optimal,and the type of main inclusions was approximately spherical or elliptical spherical RE radicle inclusions whose size was relatively large. | ZHANG Feng MA Changsong WANG BO ZHANG Peili MA Zhigang ZHANG Yi | 2011 | Baosteel Technical Research2011，5，2： | 12 |
| 7 | Cybersecurity Named Entity Recognition Using Bidirectional Long Short-Term Memory with Conditional Random Fields显示文摘Network texts have become important carriers of cybersecurity information on the Internet.These texts include the latest security events such as vulnerability exploitations,attack discoveries,advanced persistent threats,and so on.Extracting cybersecurity entities from these unstructured texts is a critical and fundamental task in many cybersecurity applications.However,most Named Entity Recognition(NER)models are suitable only for general fields,and there has been little research focusing on cybersecurity entity extraction in the security domain.To this end,in this paper,we propose a novel cybersecurity entity identification model based on Bidirectional Long Short-Term Memory with Conditional Random Fields(Bi-LSTM with CRF)to extract security-related concepts and entities from unstructured text.This model,which we have named XBi LSTM-CRF,consists of a word-embedding layer,a bidirectional LSTM layer,and a CRF layer,and concatenates X input with bidirectional LSTM output.Via extensive experiments on an open-source dataset containing an office security bulletin,security blogs,and the Common Vulnerabilities and Exposures list,we demonstrate that XBi LSTM-CRF achieves better cybersecurity entity extraction than state-of-the-art models. | Pingchuan Ma Bo Jiang Zhigang Lu Ning Li Zhengwei Jiang | 2021 | Tsinghua Science and Technology2021，26，3： | 9 |

| 9 | The plate contact geometry investigation based on earthquake source parameters at the Burma arc subduction zone显示文摘Accurately characterizing the three-dimensional geometric contacts between the crust of the Chinese mainland and adjacent regions is important for understanding the dynamics of this part of Asia from the viewpoint of global plate systems.In this paper,a method is introduced to investigate the geometric contacts between the Eurasian and Indian plates at the Burma arc subduction zone using earthquake source parameters based on the Slab1.0 model of Hayes et al.(2009,2010).The distribution of earthquake focus depths positioned in 166 sections along the Burma Arc subduction zone boundary has been investigated. Linear plane fitting and curved surface fitting has been performed on each section.Three-dimensional geometric contacts and the extent of subduction are defined quantitatively.Finally,the focal depth distribution is outlined for six typical sections along the Burma arc subduction zone,combining focal mechanisms with background knowledge of geologic structure.Possible dynamic interaction patterns are presented and discussed.This paper provides an elementary method for studying the geometric contact of the Chinese mainland crust with adjacent plates and serves as a global reference for dynamic interactions between plates and related geodynamic investigations. | ZHANG LangPing SHAO ZhiGang MA HongSheng WANG XingZhou LI ZhiHai | 2013 | Science China Earth Sciences2013，56，5： | 8 |
| 10 | FHY3 and FAR1 Integrate Light Signals with the miR156-SPL Module-Mediated Aging Pathway to Regulate Arabidopsis Flowering显示文摘In response to competition for light from their neighbors,shade-intolerant plants flower precociously to ensure reproductive success and survival.However,the molecular mechanisms underlying this key developmental switch are not well understood.Here,we show that a pair of Arabidopsis transcription factors essential for phytochrome A signaling,FAR-RED ELONGATED HYPOCOTYL3(FHY3)and FAR-RED IMPAIRED RESPONSE1(FAR1),regulate flowering time by integrating environmental light signals with the miR156-SPL module-mediated aging pathway.We found that FHY3 and FAR1 directly interact with three flowering-promoting SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE(SPL)transcription factors,SPL3,SPL4,and SPL5,and inhibit their binding to the promoters of several key flowering regulatory genes,including FRUITFUL(FUL),LEAFY(LFY),APETALA1(AP1),and MIR172C,thus downregulating their transcript levels and delaying flowering.Under simulated shade conditions,levels of SPL3/4/5 proteins increase,whereas levels of FHY3 and FAR1 proteins decline,thus releasing SPL3/4/5 from FHY3/FAR1 inhibition to allow activation of FUL,LFY,AP1,and MIR172C and,consequently,early flowering.Taken together,these results unravel a novel mechanism whereby plants regulate flowering time by integrating environmental cues(such as light conditions)and an internal developmental program(the miR156-SPL module-mediated aging pathway). | Yurong Xie Qin Zhou Yongping Zhao Quanquan Li Yang Liu Mengdi Ma Baobao Wang Rongxin Shen Zhigang Zheng Haiyang Wang | 2020 | Molecular Plant2020，13，3： | 8 |
| 11 | Effects of calcium treatment on non-metallic inclusions and magnetic properties of non-oriented silicon steel sheets显示文摘Based on the industrial production of non-oriented silicon steel,calcium treatment by CaSi wire feeding during the RH refining process was studied.The thermodynamics of CaS inclusion formation was analyzed,and the morphology and the size distribution were observed.Furthermore,the change in inclusion characteristics after calcium treatment and the effect of calcium treatment on magnetic properties were discussed.The results show that the formation of MnS and AlN inclusions were restrained,and the aggregating,floating and removing of microinclusions after calcium treatment were effectively promoted.The cleanliness of liquid steel was obviously increased.The main type of inclusions was single phase of CaO,with some complex inclusions composed of CaO,SiO2 and MgO.No CaS inclusion was observed after an appropriate calcium treatment.The size of all inclusions was distributed in the range of 2-20 μm,and the number was about 1.8×105 /mm3.In addition,as an increasing amount of calcium was added,the core loss gradually decreased to a stable level,and the magnetic induction decreased quickly after a slow increase.The optimal calcium treatment mode depends on the chemical composition of steel. | ZHANG Feng MIAO Lede ZONG Zhenyu WANG Bo ZHANG Yi MA Zhigang | 2013 | Baosteel Technical Research2013，7，1： | 7 |
| 12 | Histological, hormonal and transcriptomic reveal the changes upon gibberellin-induced parthenocarpy in pear fruit显示文摘Phytohormones play crucial roles in fruit set regulation and development.Here,gibberellins(GA4+7),but not GA3,induced pear parthenocarpy.To systematically investigate the changes upon GA4+7 induced pear parthenocarpy,dynamic changes in histology,hormone and transcript levels were observed and identified in unpollinated,pollinated and GA4+7-treated ovaries.Mesocarp cells continued developing in both GA4+7-treated and pollinated ovaries.In unpollinated ovaries,mesocarp cells stopped developing 14 days after anthesis.During fruit set process,GA4+7,but not GA1+3,increased after pollination.Abscisic acid(ABA)accumulation was significantly repressed by GA4+7 or pollination,but under unpollinated conditions,ABA was produced in large quantities.Moreover,indole-3-acetic acid biosynthesis was not induced by GA4+7 or pollination treatments.Details of this GA–auxin–ABA cross-linked gene network were determined by a comparative transcriptome analysis.The indole-3-acetic acid transport-related genes,mainly auxin efflux carrier component genes,were induced in both GA4+7-treated and pollinated ovaries.ABA biosynthetic genes of the 9-cis-epoxycarotenoid dioxygenase family were repressed by GA4+7 and pollination.Moreover,directly related genes in the downstream parthenocarpy network involved in cell division and expansion(upregulated),and MADS-box family genes(downregulated),were also identified.Thus,a model of GA-induced hormonal balance and its effects on parthenocarpy were established. | Lulu Liu Zhigang Wang Jianlong Liu Fengxia Liu Rui Zhai Chunqin Zhu Huibin Wang Fengwang Ma Lingfei Xu | 2018 | Horticulture Research2018，5，1： | 7 |
| 13 | Component characteristics of organic matter in hydrothermal barnacle shells from Southwest Indian Ridge显示文摘In 2008–2009,hydrothermal barnacle and sediment samples were collected from the Southwest Indian Ridge during a survey of the China Ocean Mineral Resources R&D Association(COMRA).Samples were analyzed by gas chromatography-mass spectrometer(GC-MS),revealing the main organic constituents of hydrothermal barnacle and sediment to be fatty acids and alkylbenzenes.N-alkanes which possessed obvious even carbon advantage were also detected in hydrothermal sediment.The high concentrations of aromatic compounds might be the result of macromolecular thermal alteration.Microorganism in the submarine hydrothermal ecosystem,especially those related to sulfur metabolism,might be the source of the high concentrations of fatty acids detected in these samples.In high temperature and high pressure hydrothermal environments,n-alkanes which possessed obvious even carbon advantage might originate from thermal alteration of carboxylic acids and other lipid compounds. | HUANG Xin ZENG Zhigang CHEN Shuai YIN Xuebo WANG Xiaoyuan ZHAO Huijing YANG Baoju RONG Kunbo MA Yao | 2013 | Acta Oceanologica Sinica2013，32，12： | 6 |
| 14 | Geochemical and Sr-Nd-Pb isotopic compositions of volcanic rocks from the Iheya Ridge,the middle Okinawa Trough:implications for petrogenesis and a mantle source显示文摘As an active back-arc basin, the Okinawa Trough is located in the southeastern region of the East China Sea shelf and is strongly influenced by the subduction of the Philippine Sea Plate. Major element, trace element and Sr-NdPb isotopic composition data are presented for volcanic rocks from the Iheya Ridge(IR), the middle Okinawa Trough. The IR rocks record large variations in major elements and range from basalts to rhyolites. Similar trace element distribution characteristics together with small variations in ^(87)Sr/^(86)Sr(0.703 862–0.704 884), ^(144)Nd/^(143)Nd(0.512 763–0.512 880) and Pb isotopic ratios, demonstrate that the IR rocks are derived from a similar magma source. The fractional crystallization of olivine, clinopyroxene, plagioclase, and amphibole, as well as accessory minerals, can reasonably explain the compositional variations of these IR rocks. The simulations suggest that approximately 60% and 75% fractionation of an evolved basaltic magma can produce trace element compositions similar to those of the intermediate rocks and acid rocks, respectively. The analysis of their Sr-Nd-Pb isotopic content ratios suggest that the source of the rocks from the IR is close to the depleted mantle(DM) but extends to the enriched mantle(EMII), indicating that the mantle source of these rocks is a mixture between the DM and EMII end members. The simulations show that the source of the IR volcanic rocks can be best interpreted as the result of the mixing of approximately 0.8%–2.0% subduction sediment components and 98.0%–99.2% mantlederived melts. | LI Xiaohui ZENG Zhigang CHEN Shuai MA Yao YANG Huixin ZHANG Yuxiang CHEN Zuxing | 2018 | Acta Oceanologica Sinica2018，37，1： | 6 |
| 15 | From Green Super Rice to green agriculture:Reaping the promise of functional genomics research显示文摘Producing sufficient food with finite resources to feed the growing global population while having a smaller impact on the environment has always been a great challenge.Here,we review the concept and practices of Green Super Rice(GSR)that have led to a paradigm shift in goals for crop genetic improvement and models of food production for promoting sustainable agriculture.The momentous achievements and global deliveries of GSR have been fueled by the integration of abundant genetic resources,functional gene discoveries,and innovative breeding techniques with precise gene and whole-genome selection and efficient agronomic management to promote resource-saving,environmentally friendly crop production systems.We also provide perspectives on new horizons in genomic breeding technologies geared toward delivering green and nutritious crop varieties to further enhance the development of green agricul-ture and better nourish the world population. | Sibin Yu Jauhar Ali Shaochuan Zhou Guangjun Ren Huaan Xie Jianlong Xu Xinqiao Yu Fasong Zhou Shaobing Peng Liangyong Ma Dingyang Yuan Zefu Li Dazhou Chen Ruifeng Zheng Zhigang Zhao Chengcai Chu Aiqing You Yu Wei Susong Zhu Qiongyao Gu Guangcun He Shigui Li Guifu Liu Changhua Liu Chaopu Zhang Jinghua Xiao Lijun Luo Zhikang Li Qifa Zhang | 2022 | Molecular Plant2022，15，1： | 6 |
| 16 | Intrinsic control of axon regeneration显示文摘Spinal cord injury disrupts the connections between the brain and spinal cord, often resulting in the loss of sensory and motor function below the lesion site. The most important reason for such permanent functional deficits is the failure of injured axons to regenerate after injury. In principle, the functional recovery could be achieved by two forms of axonal regrowth: the regeneration of lesioned axons which will reconnect with their original targets and the sprouting of spared axons that form new circuits and compensate for the lost function. Our recent studies reveal the activity of the mammalian target of rapamycin (mTOR) pathway, a major regulator of new protein synthesis, as a critical determinant of axon regrowth in the adult retinal ganglion neurons[1]. In this review, I summarize current understanding of the cellular and molecular mechanisms that control the intrinsic regenerative ability of mature neurons. | Zhigang He F.M.

| 17 | PbGA2ox8 induces vascular-related anthocyanin accumulation and contributes to red stripe formation on pear fruit显示文摘Fruit with stripes,which are generally longitudinal,can occur naturally,but the bioprocesses underlying this phenomenon are unclear.Previously,we observed an atypical anthocyanin distribution that caused red-striped fruit on the spontaneous pear bud sport“Red Zaosu”(Pyrus bretschneideri Rehd.).In this study,comparative transcriptome analysis of the sport and wild-type“Zaosu”revealed that this atypical anthocyanin accumulation was tightly correlated with abnormal overexpression of the gene-encoding gibberellin(GA)2-beta-dioxygenase 8,PbGA2ox8.Consistently,decreased methylation was also observed in the promoter region of PbGA2ox8 from“Red Zaosu”compared with“Zaosu”.Moreover,the GA levels in“Red Zaosu”seedlings were lower than those in“Zaosu”seedlings,and the application of exogenous GA4 reduced abnormal anthocyanin accumulation in“Red Zaosu”.Transient overexpression of PbGA2ox8 reduced the GA4 level and caused anthocyanin accumulation in pear fruit skin.Moreover,the presence of red stripes indicated anthocyanin accumulation in the hypanthial epidermal layer near vascular branches(VBs)in“Red Zaosu”.Transient overexpression of PbGA2ox8 resulting from vacuum infiltration induced anthocyanin accumulation preferentially in calcium-enriched areas near the vascular bundles in pear leaves.We propose a fruit-striping mechanism,in which the abnormal overexpression of PbGA2ox8 in“Red Zaosu”induces the formation of a longitudinal array of anthocyanin stripes near vascular bundles in fruit. | Rui Zhai Zhigang Wang Chengquan Yang Kui Lin-Wang Richard Espley Jianlong Liu Xieyu Li Zhongying Wu Pengmin Li Qingmei Guan Fengwang Ma Lingfei Xu | 2019 | Horticulture Research2019，6，1： | 5 |

| 19 | Adipocyte-derived SFRP5 inhibits breast cancer cells migration and invasion through Wnt and epithelial-mesenchymal transition signaling pathways显示文摘Objective:Obesity is closely associated with metastasis in breast cancer patients.Secreted frizzled-related protein 5(SFRP5),one of the novel adipokines with anti-inflammatory properties,is associated with obesity.This study aims to study the role of SFRP5 in the crosstalk between obesity and breast cancer metastasis and identify the underlying mechanism.Methods:3T3-L1 pre-adipocytes were differentiated to mature adipocytes and a hypertrophic adipocyte model was induced with palmitic acid(PA).Cell motility was measured in MDA-MB-231 and MCF-7 breast cancer cells co-cultured with adipocytes conditioned medium(CM)with or without SFRP5 protein.Wnt and epithelialmesenchymal transition(EMT)signal pathways were investigated by western blot.Circulating SFRP5 level in 218 breast cancer patients and the association with clinicopathologic characteristics of breast cancer were further determined.Online databases ENCORI and PREDICT Plus were used to exam the link between SFRP5 and prognosis.Results:Reduced SFRP5 level was detected in the hypertrophic adipocyte model.Recombinant SFRP5 protein inhibited MDA-MB-231 and MCF-7 cells invasion and migration induced by PA-treated adipocyte CM,and SFRP5 inhibition by specific antibody reversed the effect of SFRP5.Furthermore,SFRP5 significantly inhibited Wnt and downstream EMT in breast cancer cells.Low circulating SFRP5 level correlated with body mass index(BMI),lymph node(LN)metastasis,TNM stage and high Ki67 expression in breast cancer patients.Increased SFRP5 level was associated with favorable predicted survival.Kaplan-Meier curves showed high SFRP5 level in tumor tissue was associated with better outcome of breast cancer patients.Conclusions:Our findings demonstrated SFRP5 is a vital adipokine that mediates the crosslink between obesity and the metastatic potential of breast cancer.Promotion of SFRP5 expression in the adipose microenvironment may represent a novel approach for preventing breast cancer metastasis. | Wenzhong Zhou Chunmiao Ye Liang Li Liyuan Liu Fei Wang Lixiang Yu Fei Zhou Yujuan Xiang Yongjiu Wang Gengshen Yin Zhongbing Ma Qinye Fu Qiang Zhang Dezong Gao Shuya Huang Zhigang Yu | 2020 | Chinese Journal of Cancer Research2020，32，3： | 5 |
| 20 | Clinical applications of free medial tibial flap with posterior tibial artery for head and neck reconstruction after tumor resection显示文摘Tumor resection causes damage in the head and neck which creates problems in swallowing, chewing, articulation,and vision, all of which seriously affect patients' quality of life. In this work, we evaluated the application of a free medial tibial flap in reconstruction of head and neck defects after tumor resection. We discussed the anatomy,surgical technique, and the advantages and disadvantages of the flap. We found several benefits for the flap, such as,it is especially effective for the defects that require thin-layer epithelium to cover or the separated soft tissue defect;a two-team approach can be used because the donor site is far away from the head and neck; and the flap is easy to integrate because of the subcutaneous fat layer of the free medial tibial flap is thin and the flap is soft. Thus, the medial tibial flap could replace the forearm flap for certain applications. | Qi Zhong Jugao Fang Zhigang Huang Xiaohong Chen Lizhen Hou Yang Zhang Pingdong Li Hongzhi Ma Hongbo Xu | 2017 | Chinese Journal of Cancer Research2017，29，3： | 5 |
