| 2 | Characteristics of strike-slip inversion structures of the Karatau fault and their petroleum geological significances in the South Turgay Basin,Kazakhstan显示文摘The Karatau fault is one of the important strike-slip faults in central Asia,and the South Turgay Basin is located towards its northern end.Detailed seismic interpretation indicated that the strikeslip tectonism of the Karatau fault weakened gradually from west to east in the South Turgay Basin.Typical flower structures developed on the section,and strike-slip faults showed an echelon pattern on planar view.The Karatau strike-slip fault affected the South Turgay Basin in two periods:(1) The South Turgay strike-slip pull-apart rift basin formed as a result of regional extensive stress in the Early-Middle Jurassic,characterized by the juxtaposition of horsts and grabens.The formation of horsts provided favorable reservoir spaces for later hydrocarbon accumulation,and different filling stages of grabens controlled different reservoir-forming factors in grabens.(2) Two stages of tectonic inversion occurred in the Late Jurassic and Late Cretaceous and played a crucial role in the final shape of the structure in the South Turgay Basin.The oil and gas migrated to form reservoirs and mainly concentrated in the horsts,graben slopes and in both sides of the strike-slip fault zone.In the case of the degree of accumulation of petroleum,the factor explaining why horsts are better than grabens is the strike-slip pull-apart of the South Turgay Basin,and the structure inversion of the South Turgay Basin explains why the west graben is better than the east one.Overall,the Karatau strike-slip fault played a very important role in the formation of the South Turgay Basin and its hydrocarbon accumulations. | Yin Wei Fan Zifei Zheng Junzhang Yin Jiquan Zhang Mingjun Sheng Xiaofeng Guo Jianjun Li Qiyan Lin yaping | 2012 | Petroleum Science2012，9，4： | 11 |
| 3 | Rapid growth and sterility of growth hormone gene transgenic triploid carp显示文摘Triploid carp(100%)with 150(3n=150)chromosomes were obtained by crossing the females of improved tetraploid hybrids(♀, 4n=200)of red crucian carp(♀)×common carp(♂)with the males of diploid yellow river carp(♂,2n=100).The crosses yielded transgenic triploid carp(positive triploid fish,44.2%of the progeny)and non-transgenic triploid carp(negative triploid fish). Histological examination of the gonads of 24-month-old positive triploid fish suggested they were sterile and the fish were not able to produce mature gametes during the breeding season.Morphologically,both the positive and negative triploid fish were similar.They had a spindle-shaped,laterally compressed,steel grey body with two pairs of barbells.Most of the quantifiable traits of the triploid carp were intermediate between those of the two parents.The positive and negative triploid fish were raised in the same pond for 2 years.The mean body weight of the positive triploid fish was 2.3 times higher than the negative triploid fish.The weight of the largest positive triploid fish was 2.91 times higher than that of the largest negative triploid fish.Thus,we produced fast-growing transgenic triploid carp that have a reduced ecological risk because of their inability to mate and produce progeny. | YU Fan XIAO Jun LIANG XiangYang LIU ShaoJun ZHOU GongJian LUO KaiKun LIU Yun HU Wei WANG YaPing ZHU ZuoYan | 2011 | Chinese Science Bulletin2011，56，16： | 11 |

| 5 | A Rapid and Automatic Optimal Design Method for Six-Stage Axial-Flow Industry Compressor显示文摘Existing aerodynamic design systems for multi-stage axial-flow compressor suffer from several limitations,such as experience dependent models and time costly simulations.Few attempts,however,have been devoted to the rapid and automatic optimization of aerodynamic performance at the preliminary design phase,which plays a crucial role in the final aerodynamic performance.In this work,a rapid and automatic aerodynamic optimal design method is developed for the multi-stage axial-flow compressor based on one-dimensional meanline design method,radial-equilibrium equation and genetic algorithm.The one-dimensional performance prediction model includes some popular empirical correlations to calculate the flow loss,incidence angle,deviation angle and flow blockage.The radial-equilibrium equation is solved to obtain the spanwise distribution of aerodynamic and thermodynamic parameters at the inlet and outlet of each blade row.The genetic algorithm is used for an automatic search of the global optimal compressor configuration aiming at maximizing the design efficiency.The developed method is illustrated with the aerodynamic optimal design of a 6-stage axial-flow industry compressor and verified by computational fluid dynamics simulations.The results show that the developed method is capable of improving effectively the design efficiency and predicting accurately the aerodynamic performance of the 6-stage axial-flow industry compressor in a few minutes.This work is of scientific significance to improve the axial-flow compressor design system and of engineering importance to release the designers from the heavy experience dependence especially at the preliminary design phase. | LEI Fan JU Yaping ZHANG Chuhua | 2021 | Journal of Thermal Science2021，30，5： | 3 |
| 6 | Genotypic variation in spatiotemporal distribution of canopy light interception in relation to yield formation in cotton显示文摘Background: Within-canopy interception of photosynthetically active radiation(PAR) impacts yield and other agronomic traits in cotton(Gossypium hirsutum L.). Field experiments were conducted to investigate the influence of 6 cotton varieties(they belong to 3 different plant types) on yield, yield distribution, light interception(LI), LI distribution and the relationship between yield formation and LI in Anyang, Henan, in 2014 and 2015.Result: The results showed that cotton cultivars with long branches(loose-type) intercepted more LI than did cultivars with short branches(compact-type), due to increased LI in the middle and upper canopy. Although loose-type varieties had greater LI, they did not yield significantly higher than compact-type varieties, due to decreased harvest index. Therefore, improving the harvest index by adjusting the source-to-sink relationship may further increase cotton yield for loose-type cotton. In addition, there was a positive relationship between reproductive organ biomass accumulation and canopy-accumulated LI, indicating that enhancing LI is important for yield improvement for each cultivar. Furthermore, yield distribution within the canopy was significantly linearly related to vertical LI distribution.Conclusion: Therefore, optimizing canopy structure of different plant type and subsequently optimizing LI distribution within the cotton canopy can effectively enhance the yield. | XING Fangfang HAN Yingchun FENG Lu ZHI Xiaoyu WANG Guoping YANG Beifang FAN Zhengyi LEI Yaping DU Wenli WANG Zhanbiao XIONG Shiwu LI Xiaofei Ll Yabing | 2018 | Journal of Cotton Research2018，1，3： | 3 |
| 7 | Laser-induced Janus graphene/poly(p-phenylene benzobisoxazole)fabrics with intrinsic flame retardancy as flexible sensors and breathable electrodes for fire-fighting field显示文摘Conventional firefighting clothing and fire masks can protect firemen’s safety to a certain extent,whereas cannot perceive environmental hazards and monitor their physical status in real time.Herein,we fabricated two kinds of Janus graphene/poly(pphenylene benzobisoxazole)(PBO)fabrics by laser direct writing approach and evaluated their performance as intelligent firefighting clothes and fire masks.The results showed that the Janus graphene/PBO fabrics were virtually non-combustible and achieved the highest thermal protection time of 18.91 s ever reported in flame,which is due to the intrinsic flame-retardant nature of PBO fibers.The graphene/PBO woven fabrics-based sensor showed good repeatability and stability in human motion monitoring and NO_(2)gas detection.Furthermore,the piezoelectric fire mask was assembled with graphene/PBO nonwoven fabric as electrode layer and polyvinylidene fluoride(PVDF)electrostatic direct writing film as piezoelectric layer.The filtration efficiency of the fire mask reaches 95%for PM_(2.5)and 100%for PM_(3.0),indicating its effective filtration capability for smoke particles in fires.The respiratory resistance of the piezoelectric fire mask(46.8 Pa)was lower than that of commercial masks(49 Pa),showing that it has good wearing comfort.Besides,the piezoelectric fire mask can be sensitive to the speed and intensity of human breathing,which is essential for indirectly reflecting the health of the human body.Consequently,this work provides a facile approach to fabricate next-generation intrinsic flame-retardant smart textiles for smart firefighting. | Yu Luo Yaping Miao Huimin Wang Kai Dong Lin Hou Yanyan Xu Weichun Chen Yao Zhang Yingying Zhang Wei Fan | 2023 | Nano Research2023，16，5： | 2 |
| 8 | Salivary protease spectrum biomarkers of oral cancer显示文摘Proteases are important molecules that are involved in many physiological and pathological processes of the human body,such as growth,apoptosis and metastasis cancer cells.They are potential targets in cancer diagnosis and biotherapy.In this study,we analyzed the salivary protease spectrum of patients with oral squamous cell carcinoma (OSCC),oral benign masses and chronic periodontitis,as well as that of health,using human protease array kits,enzyme-linked immunosorbent assay,western blot and immunofluorescence.The salivary protease spectrum was found to be associated with oral diseases.For example,the saliva of patients with OSCC contained increased numbers of proteases than those of other oral diseases and health.The levels of matrix metalloproteinase (MMP)-1,MMP-2,MMP-10,MMP-12,A disintegrin and metalloprotease (ADAM)9,A disintegrin and metalloprotease with thrombospondin type 13 motifs (ADAMST13),cathepsin V and kallikrein 5 in the saliva of patients with OSCC were significantly increased compared with those of other groups.Taking MMP-1,cathepsin V,kallikrein 5 and ADAM9 as biomarkers of OSCC,cutoff values were199,11.34,9.29 and 202.55 pg·mL?1,respectively.From the area under the curve,sensitivity and specificity,the combination of cathepsin V/kallikrein5/ADAM9 was an optimal biomarker for diagnosing OSCC.Thus,analysis of the salivary protease spectrum may be an innovative and cost-efficient approach to evaluating the health status of the oral cavity.Specifically,increases in cathepsin V,kallikrein 5 and ADAM9 may be useful biomarkers in the screening and diagnosis of OSCC. | Yun Feng Qian Li Jiao Chen Ping Yi Xin Xu Yaping Fan Bomiao Cui Yu Yu Xiaoying Li Yue Du Qianming Chen Lingling Zhang Jingjing Jiang Xuedong Zhou Ping Zhang | 2019 | International Journal of Oral Science2019，11，2： | 2 |
| 9 | Three-dimensional silk fibroin scaffolds enhance the bone formation and angiogenic differentiation of human amniotic mesenchymal stem cells:a biocompatibility analysis显示文摘Silk fibroin(SF)is a fibrous protein with unique mechanical properties,adjustable biodegradation,and the potential to drive differentiation of mesenchymal stem cells(MSCs)along the osteogenic lineage,making SF a promising scaffold material for bone tissue engineering.In this study,hAMSCs were isolated by enzyme digestion and identified by multiple-lineage differentiation.SF scaffold was fabricated by freeze-drying,and the adhesion and proliferation abilities of hAMSCs on scaffolds were determined.Osteoblast differentiation and angiogenesis of hAMSCs on scaffolds were further evaluated,and histological staining of calvarial defects was performed to examine the cocultured scaffolds.We found that hAMSCs expressed the basic surface markers of MSCs.Collagen type I(COLI)expression was observed on scaffolds cocultured with hAMSCs.The scaffolds potentiated the proliferation of hAMSCs and increased the expression of COL-I in hAMSCs.The scaffolds also enhanced the alkaline phosphatase activity and bone mineralization,and upregulated the expressions of osteogeniorelated factors in vitro.The scaffolds also enhanced the an gioge nic differe ntiati on of hAMSCs.The cocultured scaffolds in creased bone formati on in treating critical calvarial defects in mice.This study first demonstrated that the application of 3D SF scaffolds co-cultured with hAMSCs greatly enhaneed osteogenic differentiation and angiogenesis of hAMSCs in vitro and in vivo.Thus,3D SF scaffolds cocultured with hAMSCs may be a better alter native for bone tissue engin eering. | Yuwan Li Ziming Liu Yaping Tang Qinghong Fan Wei Feng Changqi Luo Guangming Dai Zhen Ge Jun Zhang Gang Zou Yi Liu Ning Hu Wei Huang | 2020 | Acta Biochimica et Biophysica Sinica2020，52，6： | 2 |

| 11 | Assessing the effects of oyster/kelp weight ratio on water column properties: an experimental IMTA study at Sanggou Bay, China显示文摘Integrated Multi-Trophic Aquaculture(IMTA)is an effective method for sustainable aquaculture as species from different trophic levels could reduce negative effects from fed species in the environment.A proper proportion of different trophic species in an IMTA system could improve the aquaculture production and environmental sustainability.At present,research on the proper proportions for farming species is scarce.We investigated the effects of IMTA modes of oyster(Crassostrea gigas)and kelp(Saccharina japonica)in different weight ratios on water quality and carbonate system in a closed enclosure experiment for three days in the Sanggou Bay in Shandong Province,China,in December 2017.Nine collocation modes in oyster:kelp weight ratio were tested showing as 24:3,24:2,24:1,16:3,16:2,16:1,8:3,8:2,and 8:1.The water parameters were determined at 17:00 on Day 1(D1),and 6:00 and 17:00 on Days 2(D2)and 3(D3).As two-way ANOVA showed,all increased parameters(dissolved oxygen(DO),pH,chl a,the carbonate system and pCO2)were significantly related to oyster-kelp modes,and interaction between modes and time were also significant(P<0.05).On the 3th day,the 8:3 mode was the highest in DO,pH,chl a,CO32-(P<0.05),and dissolved inorganic carbon(DIC),HCO3-,CO2,and pCO2 were the lowest(P<0.05).According to previous references and the results of this study,the appropriate oyster:kelp proportion at the beginning of winter is from 8:2 to 8:3.The results of this study may help government to optimize the aquaculture structure of Sanggou Bay. | FANG Jinghui FANG Jianguang CHEN Qionglin MAO Yuze JIANG Zengjie DU Meirong GAO Yaping LIN Fan | 2020 | Journal of Oceanology and Limnology2020，38，6： | 2 |
| 12 | Genomic and transcriptomic analysis unveils population evolution and development of pesticide resistance in fall armyworm Spodoptera frugiperda显示文摘The fall armyworm(FAW),Spodoptera frugiperda,is a destructive pest native to America and has recently become an invasive insect pest in China.Because of its rapid spread and great risks in China,understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies.Here,we assembled a chromosome-level genome of a male FAW(SFynMstLFR)and compared re-sequencing results of the populations from America,Africa,and China.Strain identification of 163 individuals collected from America,Africa and China showed that both C and R strains were found in the American pop-ulations,while only C strain was found in the Chinese and African populations.Moreover,population geno-mics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations.Taken toge-ther,FAWs invaded into China were most likely origi-nated from Africa.Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW,of which 283 genes are specific to FAW.Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles,and several detoxification genes such as AOX,UGT and GST spe-cially responded to the pesticides.These findings will be useful in developing effective strategies for manage-ment of FAW in China and other invaded areas. | Furong Gui Tianming Lan Yue Zhao Wei Guo Yang Dong Dongming Fang Huan Liu Haimeng Li Hongli Wang Ruoshi Hao Xiaofang Cheng Yahong Li Pengcheng Yang Sunil Kumar Sahu Yaping Chen Le Cheng Shuqi He Ping Liu Guangyi Fan Haorong Lu Guohai Hu Wei Dong Bin Chen Yuan Jiang Yongwei Zhang Hanhong Xu Fei Lin Bernard Slippers Alisa Postma Matthew Jackson Birhan Addisie Abate Kassahun Tesfaye Aschalew Lemma Demie Meseret Destaw Bayeleygne Dawit Tesfaye Degefu Feng Chen Paul K.Kuria Zachary M.Kinyua Tong-Xian Liu Huanming Yang Fangneng Huang Xin Liu Jun Sheng Le Kang | 2022 | Protein & Cell2022，13，7： | 2 |
| 13 | OsSRK1,an Atypical S-Receptor-Like Kinase Positively Regulates Leaf Width and Salt Tolerance in Rice显示文摘Receptor-like kinases(RLKs)are important for plant growth,development and defense responses.The S-receptor protein kinases(SRKs),which represent an RLK subfamily,control the selfincompatibility among Brassica species.However,little information is available regarding SRK functions in rice.We identified a gene OsSRK1 encoding an atypical SRK.The transcript of OsSRK1 was induced by abscisic acid(ABA),salt and polyethylene glycol.OsSRK1 localized to the plasma membrane and cytoplasm.Leaf width was increased in OsSRK1-overexpression(OsSRK1-OX)transgenic rice plants,likely because of an increase in cell number per leaf.Furthermore,the expression levels of OsCYCA3-1 and OsCYCD2-1,which encode positive regulators of cell division,were up-regulated in leaf primordium of OsSRK1-OX rice plants relative to those in wild type.Meanwhile,the expression level of OsKRP1,which encodes cell cycle inhibitor,was down-regulated in the OsSRK1-OX plants.Therefore,it is deduced that OsSRK1 regulates leaf width by promoting cell division in the leaf primordium.Additionally,OsSRK1-OX plants exhibited enhanced ABA sensitivity and salt tolerance compared with wild type.These results suggest that OsSRK1 plays important roles in leaf development and salt responses in rice. | ZHOU Jinjun JU Peina ZHANG Fang ZHENG Chongke BAI Bo LI Yaping WANG Haifeng CHEN Fan XIE Xianzhi | 2020 | Rice science2020，27，2： | 2 |
| 14 | Optimal Frequency Regulation Based on Characterizing the Air Conditioning Cluster by Online Deep Learning显示文摘The air conditioning cluster(ACC)is a potential candidate to provide frequency regulation reserves.However,the effective assessment of the ACC willing reserve capacity is often an obstacle for existing demand response(DR)programs,influenced by incentive prices,temperatures,etc.In this paper,the complex relationship between the ACC willing reserve capacity and its key influence factors is defined as a demand response characteristic(DRC).To learn about DRC along with real-time frequency regulation,an online deep learning-based DRC(ODLDRC)modeling methodology is designed to continuously retrain the deep neural network-based model.The ODL-DRC model trained by incoming new data does not require massive historical training data,which makes it more time-efficient.Then,the coordinate operation between ODL-DRC modeling and optimal frequency regulation(OFR)is presented.A robust decentralized sliding mode controller(DSMC)is designed to manage the ACC response power in primary frequency regulation against any ACC response uncertainty.An ODL-DRC model-based OFR scheme is formulated by taking the learning error into consideration.Thereby,the ODL-DRC model can be applied to minimize the total operational cost while maintaining frequency stability,without waiting for a well-trained model.The simulation cases validate the superiority of the OFR based on characterizing the ACC by online learning,which can capture the real DRC and simultaneously optimize the regulation performance with strong robustness against any ACC response uncertainty and learning error. | Yeyan Xu Liangzhong Yao Siyang Liao Yaping Li Jian Xu Fan Cheng | 2022 | CSEE Journal of Power and Energy Systems2022，8，5： | 2 |

| 20 | Longitudinal residual circulation in the South Passage of Yangtze Estuary:Combined influences from runoff,tide and bathymetry显示文摘Classical estuary circulation theory states that in the longitudinal direction of an estuary there exists a single circulation with landward,near-bottom,and seaward,near-surface flows;however,the situation becomes complicated with the presence of a river mouth bar.Here we conducted tidal-cycle observations in the South Passage of the Yangtze Estuary during both the wet and dry seasons of 2018(July and December,respectively).The simultaneous current velocity,temperature,and salinity profile data were obtained from anchored boats and base tripods at three stations along the channel in the mouth bar area.The results reveal two distinct longitudinal residual circulation patterns:a classic circulation which is formed on the seaward slope of the mouth bar during the wet season,and a double circulation system which is composed of two circulation cells over the landward and seaward slopes of the mouth bar during the dry season.The Simpson number(Si),mixing parameter(M),and salinity data were used to quantify the mixing intensity,which shows that horizontal baroclinic pressure gradient is the dominant factor in the formation of the longitudinal residual circulation.Furthermore,the double circulation pattern during the dry season is related to the mouth bar bathymetry,which affects saltwater intrusion.The double circulations can significantly influence the spatial and temporal evolution of the stagnation point in the estuarine channel,which in turn modifies the distribution patterns of suspended sediment concentration in the maximum turbidity zone.Evidently,the changes in the mouth bar sandbar bathymetry in response to human activities and river basin hydrographic conditions indirectly affect the occurrence and scale of the double circulations. | Lifen ZHANG Zuosheng YANG Fan ZHANG Zhanhai LI Yaping WANG Shu GAO | 2021 | Science China Earth Sciences2021，64，12： | 1 |
