| 1 | SHRIMP U-Pb dating for a K-bentonite bed in the Tieling Formation,North China显示文摘A SHRIMP U-Pb zircon age of 1437±21 Ma was obtained for a recently discovered K-bentonite bed in the Tieling Formation,situated northeast of Beijing at the boundary between Liaoning and Hebei provinces,on the northern margin of the North China Craton(NCC).The SHRIMP U-Pb age places Tieling Formation near the end of the Calymmian Period of the early Mesoproterozoic Era.In addition,a SHRIMP U-Pb zircon date of 1372±18 Ma was acquired for K-bentonite beds in the overlying,dark-shale-dominated Xiamaling Formation from the same location northeast of Beijing.This date assigns a similar Mid-Mesoproterozoic(Ectasian Period) age for the Xiamaling Formation,as have previously determined dates from other sections northwest of Beijing.These dates indicate that the Tieling and Xiamaling formations,as well as the related succession in the eastern part of the Yanshan Mountains,represented by the well-known Meso-to Neoproterozoic standard section in Jixian,can be correlated well with sections northwest of Beijing in the western part of the Yanshan Mountains.In other words,the boundary between the Calymmian and Ectasian periods in the northern parts of the NCC is marked by the unconformity between the Tieling and Xiamaling formations in the northern NCC.This boundary was previously ascribed to the 'Qinyu Orogeny' and thought to be of Grenville age.In this regard,the conventional 'Qinyu Orogeny' should now be regarded as a short-lived regional uplift during Early Mesoproterozoic time,rather than a result from the Grenvillian assembly of the NCC to the Rodinia Supercontinent(~1.0 Ga). | SU WenBo LI HuaiKun HUFF W D ETTENSOHN F R ZHANG ShiHong ZHOU HongYing WAN YuSheng | 2010 | Chinese Science Bulletin2010，55，29： | 30 |
| 2 | Estimation of ammonia nitrogen load from nonpoint sources in the Xitiao River catchment, China显示文摘Ammonia nitrogen (NH4+-N) is one of the three main forms of total nitrogen (TN). Most studies have estimated the load of TN from nonpoint sources instead of one specific form. The relationship between land use and concentrations of NH4+-N in runoff was analyzed using the hydraulic analysis functions of a Geographic Information Systems (GIS), and the annual loads of NH4+-N in the Xitiao River catchment were estimated according to model results. The results suggested that the calculated annual loads of NH4+-N agreed well with the observed ones, which was a good example demonstrating that it was possible to estimate the pollutant loads from nonpoint sources without enough monitoring data. Results also showed that the concentrations of NH4+-N in river waters of forest and arable land in the study area were 0.16 and 0.39 mg/L, respectively. The total nonpoint source load of NH4+-N from 1995 to 2001 (except 1998 and 2000) varied between 2,098 and 7,992 tons/year in the Xitiao River catchment. | Tao LIANG Zhongyi CHONG | 2008 | Journal of Environmental Sciences2008，20，10： | 13 |

| 4 | Natural Variations at TIG1 Encoding a TCP Tran scription Factor Contribute to Plant Architecture Domestication in Rice显示文摘The modification of plant architecture is a crucial target in rice domestication and modern genetic improvement.Although several genes regulating rice plant architecture have been characterized,the molecular mechanisms underlying rice plant architecture domestication remain largely unclear.Here we show that the inclined tiller growth in wild rice is controlled by a single dominant gene,TILLER INCLINED GROWTH 1 (T/Gf),which is located on chromosome 8 and encodes a TCP transcriptional activator.TIG1 is primarily expressed in the adaxial side of the tiller base,promotes cell elongation,and enlarges the tiller angle in wild rice.Variations in the TIG1 promoter of indica cultivars {tig1 allele) resulted in decreased expression of TIG1 in the adaxial side of tiller base and reduced cell length and tiller angle,leading to the transition from inclined tiller growth in wild rice to erect tiller growth during rice domestication.TIG1 positively regulates the expression of EXP A3,EXPB5,and SAUR39 to promote cell elongation and increase the tiller angle.Selective sweep analysis revealed that the tig1 allele was selected in indica cultivars by human beings.The cloning and characterization of TIG1 supports a new scenario of plant architecture evolution in rice. | Weifeng Zhang Lubin Tan Hongying Sun Xinhui Zhao Fengxia Liu Hongwei Cai Yongcai Fu Xianyou Sun Ping Gu Zuofeng Zhu Chuanqing Sun | 2019 | Molecular Plant2019，12，8： | 13 |

| 6 | Graft-accelerated virus-induced gene silencing facilitates functional genomics in rose flowers显示文摘Rose has emerged as a model ornamental plant for studies of flower development, senescence, and morphology, as well as the metabolism of floral fragrances and colors.Virus-induced gene silencing(VIGS) has long been used in functional genomics studies of rose by vacuum infiltration of cuttings or seedlings with an Agrobacterium suspension carrying TRV-derived vectors. However, VIGS in rose flowers remains a challenge because of its low efficiency and long time to establish silencing. Here we present a novel and rapid VIGS method that can be used to analyze gene function in rose,called ‘graft-accelerated VIGS', where axil ary sprouts are cut from the rose plant and vacuum infiltrated with Agrobacterium. The inoculated scions are then grafted back onto the plants to flower and silencing phenotypes can be observed within 5 weeks, post-infiltration. Using this new method, we successfully silenced expression of the RhDFR_1, RhA G, and RhNUDX_1 in rose flowers, and affected their color, petal number, as well as fragrance, respectively. This grafting method will facilitate high-throughput functional analysis of genes in rose flowers. Importantly, it may also be applied to other woody species that are not currently amenable to VIGS by conventional leaf or plantlet/seedling infiltration methods. | Huijun Yan Shaochuan Shi Nan Ma Xiaoqian Cao Hao Zhang Xianqin qiu Qigang Wang Hongying Jian Ningning Zhou Zhao Zhang Kaixue Tang | 2018 | Journal of Integrative Plant Biology2018，60，1： | 11 |
| 7 | Single-shot BOTDA based on an optical chirp chain probe wave for distributed ultrafast measurement显示文摘Brillouin optical time-domain analysis(BOTDA)requires frequency mapping of the Brillouin spectrum to obtain environmental information(e.g.,temperature or strain)over the length of the sensing fiber,with the finite frequencysweeping time-limiting applications to only static or slowly varying strain or temperature environments.To solve this problem,we propose the use of an optical chirp chain probe wave to remove the requirement of frequency sweeping for the Brillouin spectrum,which enables distributed ultrafast strain measurement with a single pump pulse.The optical chirp chain is generated using a frequency-agile technique via a fast-frequency-changing microwave,which covers a larger frequency range around the Stokes frequency relative to the pump wave,so that a distributed Brillouin gain spectrum along the fiber is realized.Dynamic strain measurements for periodic mechanical vibration,mechanical shock,and a switch event are demonstrated at sampling rates of 25 kHz,2.5 MHz and 6.25 MHz,respectively.To the best of our knowledge,this is the first demonstration of distributed Brillouin strain sensing with a wide-dynamic range at a sampling rate of up to the MHz level. | Dengwang Zhou Yongkang Dong Benzhang Wang Chao Pang Dexin Ba Hongying Zhang Zhiwei Lu Hui Li Xiaoyi Bao | 2018 | Light(Science & Applications)2018，7，1： | 11 |

| 9 | Advances in rheology and flow assurance studies of waxy crude显示文摘Flow assurance is one of the core issues in safe and economical operation of waxy crude pipelines.Its essence lies in flow and heat transfer of the crude.In the past 10 years,the authors' team has achieved a lot of innovative results in aspects of waxy crude rheology,flow assurance assessment,and pipelining technologies on the basis of decades of studies.The rheological characteristics of waxy crude are much better understood,and a method for quantitatively simulating the effect of flow shear was developed based on some theoretical breakthroughs.Studies of the mechanism of waxy crude rheology have been deepened to the quantitative level.After successful development of efficient numericalalgorithms,accurate simulations have been achieved for various complex flow and heat transfer situations in waxy crude pipelining,and a reliability-based approach to flow assurance assessment has been set up.New pipelining technologies have been developed such as batching pour-point depressant-(PPD-) treated multiple-waxy-crudes,intermittent transport of waxy crudes through long-distance pipelines,and batching hot and cold crudes.By their application,a series of problems hindering safe,efficient and flexible operation of waxy crude pipelines were tackled,demonstrating that transportation technologies for waxy crude have advanced to a new and high level. | Zhang Jinjun Yu Bo Li Hongying Huang Qiyu | 2013 | Petroleum Science2013，10，4： | 10 |
| 10 | Distribution and Provenance of Detrital Minerals in Southern Coast of Shandong Peninsula显示文摘Detrital minerals of 137 offshore and 22 river sediment samples collected from Qingdao coastal areas have been analyzed. Four mineral assemblage provinces can be classified by Q-mode cluster analysis. Factor analysis identifies two major factors that account for the total variability in most common minerals: 1) based on the relationship of quartz, hornblende, actinolite, micas, and authigenic pyrite, 41.55% of the variability is related to sediment sources; 2) based on the relationship of epidote, garnet, sphere, and ilmenite, 23.21% can be related to strong hydrodynamic conditions that control transport and sedimentation. By comparing mineral compositions of river waters in the study area, the following four mineral provenances can be identified. The Qingdao-Laoshan nearshore area has a quartz-feldspar-epidote-hornblende-limenite-limonite-sphene assemblage, which is largely attributed to relict sediment and coastal erosion. The Jimo-Haiyang nearshore area has a quartz-feldspar-hornblende-epidote-limonite-mica-actinolite assemblage, derived largely from the Wulong River and Rushan River, and is also affected by the Huanghe River, while the Qianliyan Island area in the deeper offshore area separated by a mud belt has a similar assemblage. The Haiyang-Rushan nearshore area has a quartz-feldspar-hornblende-epidote-micas-limonite assemblage, indicating multiple sources from the Rushan River, the Wulong River, the Huanghe River, and coastal erosion. The central area, located in an eddy center, has a mica-authigenic pyrite-hornblende-quartz-feldspar assemblage, indicating multiple sources dominated by Huanghe River distal sediments. | LIU Jinqing YIN Ping ZHANG Yong SONG Hongying BI Shipu CAO Zhimin LIU Shanshan | 2017 | Journal of Ocean University of China2017，16，5： | 9 |
| 11 | Inheritance of Perpetual Blooming in Rosa chinensis ‘Old Blush'显示文摘Perpetual blooming is one of the most important biological and economical traits in modern rose, while the genetic basis underlining the control of this trait is poorly investigated. With an aim in dissecting the genetic determinism of perpetual blooming, we developed six rose populations(OB, W, F1, F2, BC1 OB and BC1W) derived from a WOB population [interspecific diploid hybridization between Rosa chinensis ‘Old Blush'(OB) and R. wichuriana ‘Basye's Thornless'(W)]. Perpetual blooming is absent both in a F1 population with 296 individuals and a BC1 W population(W as the backcross parent) with 150 individuals. However, the perpetual blooming trait showed a typical 3︰1 segregation in a backcross population BC1 OB with OB as the backcross parent. In this population with 300 individuals, 83 plants had the perpetual blooming phenotype while the other 217 featured non-perpetual blooming, indicating that the perpetual blooming trait is very likely controlled by two recessive genes in R. chinensis(rpb1 and rpb2). These genetic data suggest that the inheritance of rose perpetual blooming may be controlled by a complex mechanism. | LI Shubin ZHOU Ningning ZHOU Qing YAN Huijun JIAN Hongying WANG Qigang CHEN Min QIU Xianqin ZHANG Hao WANG Shufang LI Shufa TANG Kaixue | 2015 | Horticultural Plant Journal2015，1，2： | 9 |
| 12 | Foxtail millet:nutritional and eating quality,and prospects for genetic improvement显示文摘Foxtail millet is a minor yet important crop in some areas of the world,particularly northern China.It has strong adaptability to abiotic stresses,especially drought,and poor soil.It also has high nutritional value.Foxtail millet is rich in essential amino acids,fatty acids and minerals,and is considered to be one of the most digestible and non-allergenic grains available and has significant importance for human health.Given foxtail millet’s ability to adapt to abiotic stresses associated with climate change,it is more important than ever to develop breeding strategies that facilitate the increasing demand for high quality grain that better satisfies consumers.Here we review research on foxtail millet quality evaluation,appearance,cooking and eating quality at the phenotypic level.We review analysis of the main nutrients in foxtail millet,their relationships and the biochemical and genetic factors affecting their accumulation.In addition,we review past progress in breeding this regionally important crop,outline current status of breeding of foxtail millet,and make suggestions to improve grain quality. | Lu HE Bin ZHANG Xingchun WANG Hongying LI Yuanhuai HAN | 2015 | Frontiers of Agricultural Science and Engineering2015，2，2： | 8 |
| 13 | Comparison of activated carbon and iron/cerium modified activated carbon to remove methylene blue from wastewater显示文摘The methylene blue(MB)removal abilities of raw activated carbon and iron/cerium modified raw activated carbon(Fe–Ce-AC)by adsorption were researched and compared.The characteristics of Fe–Ce-AC were examined by N_2adsorption,zeta potential measurement,FTIR,Raman,XRD,XPS,SEM and EDS.After modification,the following phenomena occurred:The BET surface area,average pore diameter and total pore volume decreased;the degree of graphitization also decreased.Moreover,the presence of Fe_3O_4led to Fe–Ce-AC having magnetic properties,which makes it easy to separate from dye wastewater in an external magnetic field and subsequently recycle.In addition,the equilibrium isotherms and kinetics of MB adsorption on raw activated carbon and Fe–Ce-AC were systematically examined.The equilibrium adsorption data indicated that the adsorption behavior followed the Langmuir isotherm,and the pseudo-second-order model matched the kinetic data well.Compared with raw activated carbon,the maximum monolayer adsorption capacity of Fe–Ce-AC increased by27.31%.According to the experimental results,Fe–Ce-AC can be used as an effective adsorbent for the removal of MB from dye wastewater. | Song Cheng Libo Zhang Aiyuan Ma Hongying Xia Jinhui Peng Chunyang Li Jianhua Shu | 2018 | Journal of Environmental Sciences2018，30，3： | 8 |
| 14 | Shaking table experimental study of recycled concrete frame-shear wall structures显示文摘In this study, four 1/5 scaled shaking table tests were conducted to investigate the seismic performance of recycled concrete frame-shear wall structures with different recycled aggregates replacement rates and concealed bracing detail. The four tested structures included one normal concrete model, one recycled coarse aggregate concrete model, and two recycled coarse and fi ne aggregate concrete models with or without concealed bracings inside the shear walls. The dynamic characteristics, dynamic response and failure mode of each model were compared and analyzed. Finite element models were also developed and nonlinear time-history response analysis was conducted. The test and analysis results show that the seismic performance of the recycled coarse aggregate concrete frame-shear wall structure is slightly worse than the normal concrete structure. The seismic resistance capacity of the recycled concrete frame-shear wall structure can be greatly improved by setting up concealed bracings inside the walls. With appropriate design, the recycled coarse aggregate concrete frame-shear wall structure and recycled concrete structure with concealed bracings inside the walls can be applied in buildings. | Zhang Jianwei Cao Wanlin Meng Shaobin Yu Cheng Dong Hongying | 2014 | Earthquake Engineering and Engineering Vibration2014，13，2： | 8 |
| 15 | Synthesis and applications of mesoporous Cu-Zn-Al_2O_3 catalyst for dehydrogenation of 2-butanol显示文摘A series of mesoporous Cu-Zn-Al2O3 materials have been synthesized at ambient temperature and their structure was characterized by XRD, N2 physical adsorption and TPR techniques. Their catalytic applications for the dehydrogenation of 2-butanol to methyl ethyl ketone (MEK) were evaluated in a fixed-bed flow reactor at atmospheric pressure. It is demonstrated from the XRD patterns that both the as-synthesized samples and calcined samples have the typical XRD patterns of meso-structured materials and the results of N2O chemical adsorption showed that Cu was embedded in the framework of the mesoporous materials and homogeneously dispersed in the mesoporous Cu-Zn-Al2O3 materials. The catalytic activity of 2-butanol dehydrogenation was varied in the order of CZA(10) | Deren Fang Wanzhong Ren Zhongmin Liu Xiufeng Xu Lei Xu Hongying Lǔ Weiping Liao Huimin Zhang | 2009 | Journal of Natural Gas Chemistry2009，18，2： | 7 |
| 16 | Change of BMD after Weaning or Resumption of Menstruation in Chinese Women with Different FokI VDR-genotypes:A Randomized,Placebo-controlled,Calcium Supplementation Trial显示文摘Objective To investigate the effect of calcium supplementation on bone mineral density (BMD) in Chinese women with different FokI vitamin D receptor (VDR) genotypes (FF,Ff,and ff) after weaning or resumption of menstruation during lactation.Methods A total of 40 subjects with the same FokI VDR genotype were randomly divided into two groups:one received calcium tablet (600 mg once daily as CaCO 3) and the other placebo tablet once daily for 1 year.At baseline,BMD was measured by dual‐energy X‐ray absorptiometry at lumbar spine (L2‐L4) and at left hip whereas serum PICP,serum OC,and urinary CTX,serum 25(OH)VitD 3,and serum estradiol were measured at weaning and 1 year thereafter.Results After the intervention,BMD at lumbar spine and at left hip increased significantly in all these women with a trend among different FokI VDR genotypes such as FF > Ff > ff (P<0.05,<0.01,and <0.001,respectively).BMD at lumbar spine in women with FF VDR genotype increased much more rapidly than in those with ff VDR genotype (P<0.05).Compared with the control group women with the FF genotype regained more BMD after calcium supplementation (P<0.05).Conclusion Daily calcium 600 mg supplementation has beneficial effect on the bone health of women with FF VDR genotype. | YU Bo WU HongYing LI Fang GONG Jie ZHOU DunJin ZHANG ZhiFeng YANG XiaoGuang HUANG ZhenWu | 2011 | Biomedical and Environmental Sciences2011，24，3： | 6 |
| 17 | Characteristic Temperatures of Waxy Crude Oils显示文摘Gel point or pour point is widely used to evaluate the low temperature flowability of crude oil. However, it is not adequate to describe the gelling properties of waxy crude oils under flow conditions with gel point or pour point, since the rheological behavior of crude oils is dependent on shear history. Waxy crude oils tend to gel at a low temperature. Based on gelation theory, the characteristic temperature of waxy crude oil was determined by analyzing viscosity-temperature data. Two mathematical models were developed for calculating characteristic temperatures of virgin crude oils and pour point depressants (PPD) beneficiated crude oils, respectively. By using these two models, the characteristic temperatures of crude oils that have experienced shearing and thermal histories can be predicted. The model for predicting the characteristic temperature of virgin crude oils has an average relative deviation of 4.5%, and all predicted values have a deviation within 2 ℃. Tested by 42 sets of data, the prediction model for crude oil treated with PPD has a high accuracy, with an average relative deviation of 4.2%, and 95.2 percent of predicted values have a deviation within 2 ℃. These two models provide useful ways for predicting the flowability of crude oils in pipelines when only wax content, wax appearance point and gel point are available. | Zhu Yingru Zhang Jinjun Li Hongying Chen Jun | 2007 | Petroleum Science2007，4，3： | 6 |
| 18 | Identification of odorous compounds in reclaimed water using FPA combined with sensory GC-MS显示文摘Odorous compounds in the influent of a reclaimed water treatment plant (RWTP),consisting of coagulation,sedimentation,continuous micro-filtration (CMF),and chlorination in succession,in a north China city,were identified by combining flavor profile analysis (FPA) with sensory gas chromatograph-mass spectrometry (GC-MS).The sewery/swampy/septic odor with an odor intensity of 6.4 was found to be the major odor group in the RWTP influent,and the existence of well-known odorant including dimethyl disulfide,dimethyl trisulfide,indole and skatole were confirmed using GC-MS.The result of a spiking test showed that the intensity (3.6) of the sewery/swampy/septic odor caused by these four chemicals contributed to over 50% of the odor intensity of the influent.The FPA intensity for sewery/swampy/septic odor in the RWTP effluent was 3.8,showing that the treatment process was not efficient for the removal of odorants,particularly indole and skatole. | Zhiming Yan Yu Zhang Jianwei Yu Hongying Yuan Min Yang | 2011 | Journal of Environmental Sciences2011，23，10： | 6 |
| 19 | Genome-wide CRISPR screen identifies synthetic lethality between DOCK1 inhibition and metformin in liver cancer显示文摘Metformin is currently a strong candidate anti-tumor agent in multiple cancers.However,its anti-tumor effectiveness varies among different cancers or sub-populations,potentially due to tumor heterogeneity.It thus remains unclear which hepatocellular carcinoma(HCC)patient subpopulation(s)can benefit from met-formin treatment.Here,through a genome-wide CRISPR-Cas9-based knockout screen,we find that DOCK1 levels determine the anti-tumor effects of met-formin and that DOCK1 is a synthetic lethal target of metformin in HCC.Mechanistically,metformin promotes DOCK1 phosphorylation,which activates RAC1 to facilitate cell survival,leading to metformin resistance.The DOCK1-selective inhibitor,TBOPP,potentiates anti-tumor activity by metformin in vitro in liver cancer cell lines and patient-derived HCC organoids,and in vivo in xenografted liver cancer cells and immunocompetent mouse liver cancer models.Notably,metformin improves overall survival of HCC patients with low DOCK1 levels but not among patients with high DOCK1 expression.This study shows that metformin effective-ness depends on DOCK1 levels and that combining metformin with DOCK1 inhibition may provide a promising personalized therapeutic strategy for met-formin-resistant HCC patients. | Junru Feng Hui Lu Wenhao Ma Wenjing Tian Zhuan Lu Hongying Yang Yongping Cai Pengfei Cai Yuchen Sun Zilong Zhou Jiaqian Feng Jiazhong Deng Ying Shu Kun Qu Weidong Jia Ping Gao Huafeng Zhang | 2022 | Protein & Cell2022，13，11： | 5 |
| 20 | Rational development of a human antibody cocktail that deploys multiple functions to confer Pan-SARS-CoVs protection显示文摘Structural principles underlying the composition and synergistic mechanisms of protective monoclonal antibody cocktails are poorly defined.Here,we exploited antibody cooperativity to develop a therapeutic antibody cocktail against SARS-CoV-2.On the basis of our previously identified humanized cross-neutralizing antibody H014,we systematically an a lyzed a fully human n aive antibody library and rationally identified a potent neutralizing antibody partner,P17,which confers effective protection in animal model.Cryo-EM studies dissected the nature of the P17 epitope,which is SARS-CoV-2 specific and distinctly different from that of HOI4.High-resolution structure of the SARS-CoV-2 spike in complex with HOM and P17,together with functional investigations revealed that in a two-antibody cocktail,synergistic neutralization was achieved by S1 shielding and conformational locking,thereby blocking receptor attachment and viral membrane fusion,conferring high potency as well as robustness against viral mutation escape.Furthermore,cluster analysis identified a hypothetical 3rd antibody partner for further reinforcing the cocktail as pan-SARS-CoVs therapeutics. | Hangping Yao Yao Sun Yong-Qiang Deng Nan Wang Yongcong Tan Na-Na Zhang Xiao-Feng Li Chao Kong Yan-Peng Xuc Qi Chen Tian-Shu Cao Hui Zhao Xintian Yan Lei Cao Zhe Lv Dandan Zhu Rui Feng Nanping Wu Wenhai Zhang Yuhao Hu Keda Chen Rong-Rong Zhang Qingyu Lv Shihui Sun Yunhua Zhou Run Yan Guan Yang Xinglu Chanjuan Liu Xiangyun Lu Linfang Cheng Hongying Qiu Xing-Yao Huang Tianhao Weng Danrong Shi Weidong Jiang Junbin Shao Lei Wang Jie Zhang Tao Jiang Guojun Lang Cheng-Feng Qinc Lanjuan Li Xiangxi Wang | 2021 | Cell Research2021，31，1： | 5 |
