2Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype.Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu 2021Cell Research2021,31,3:9
3Rice caryopsis development Ⅱ: Dynamic changes in the endosperm显示文摘The rice endosperm plays crucial roles in nourishing the embryo during embryogenesis and seed germination.Although previous studies have provided the general information about rice endosperm, a systematic investigation throughout the entire endosperm developmental process is still lacking. In this study, we examined in detail rice endosperm development on a daily basis throughout the 30-day period of post-fertilization development. We observed that coenocytic nuclear division occurred in the first 2 days after pollination(DAP), cellularization occurred between 3 and 5 DAP, differentiation of the aleurone and starchy endosperm occurred between 6 and 9 DAP, and accumulation of storage products occurred concurrently with the aleurone/starchy endosperm differentiation from 6 DAP onwards and was accomplished by 21 DAP. Changes in cytoplasmic membrane permeability, possibly caused by programmed cell death, were observed in the central region of the starchy endosperm at 8 DAP, and expanded to the whole starchy endosperm at 21 DAP when the aleurone is the only living component in the endosperm. Further, we observed that a distinct multi-layered dorsal aleurone formed near the dorsal vascular bundle, while the single- or occasionally two-cell layered aleurone was located in the lateral and ventral positions of endosperm. Our results provide in detail the dynamic changes in mitotic divisions, cellularization, cell differentiation, storage product accumulation, and programmed cell death that occur during rice endosperm development.Xiaoba Wu Jinxin Liu Dongqi Li Chun-Ming Liu 2016Journal of Integrative Plant Biology2016,58,9:9
4Cooperative localization method for multi-robot based on PF-EKF显示文摘A method of cooperative localization for multi-robot in an unknown environment is described.They share information and perform localization by using relative ob-servations and necessary communication.At initial time,robots do not know their positions.Once the robot that can obtain the absolute position information has its position,other robots use particle filter to fuse relative observations and maintain a set of samples respectively representing their positions.When the particles are close to a Gaussian distribution after a number of steps,we switch to an EKF to track the pose of the robots.Simulation results and real experiment show that PF-EKF method combines the robustness of PF and the efficiency of EKF.Robots can share the absolute position information and effectively localize themselves in an unknown environment.WANG Ling WAN JianWei LIU YunHui SHAO JinXin 2008Science in China(Series F)2008,51,8:7
5A probabilistic risk assessment framework considering lane-changing behavior interaction显示文摘Understanding the dynamic characteristics of surrounding vehicles and estimating the potential risk of mixed traffic can help reliable autonomous driving.However,the existing risk assessment methods are challenging to detect dangerous situations in advance and tackle the uncertainty of mixed traffic.In this paper,we propose a probabilistic driving risk assessment framework based on intention identification and risk assessment of surrounding vehicles.Firstly,we set up an intention identification model(IIM)via long short-term memory(LSTM)networks to identify the intention possibility of the surrounding vehicles.Then a risk assessment model(RAM)based on the driving safety field is employed to output the potential risk.Specifically,driving safety field can reflect the coupling relationship of drivers,vehicles,and roads by analyzing their interaction.Finally,an integrated risk evaluation model combining both IIM and RAM is developed to form a dynamic potential risk map considering multi-vehicle interaction.For example,in a typical but challenging lane-changing scenario,an intelligent vehicle can assess its driving status by calculating a risk map in real time that represents the risk generated by the estimated intentions of surrounding vehicles.Furthermore,simulations and naturalistic driving experiments are conducted in the extracted lane-changing scenarios,and the results verify the effectiveness of the proposed model considering lane-changing behavior interaction.Heye HUANG Jianqiang WANG Cong FEI Xunjia ZHENG Yibin YANG Jinxin LIU Xiangbin WU Qing XU 2020Science China(Information Sciences)2020,63,9:6
6Experimental study on influencing factors of acid-fracturing effect for carbonate reservoirs显示文摘Acid fracturing treatment is the key technique for stimulation and stable production in carbonate reservoirs.In order to improve the carbonate reservoirs acid fracturing effect,in this paper,with a large number of experiments as the main research methods,study on influencing factors of acidfracturing effect for carbonate reservoirs from increase the effective distance of living acid,increase acid corrosion eched fracture conductivity,reduce the acid fluid loss,etc.The effective distances of live acid calculated with reacted acid limitations measured in different acid systems are quite different from those calculated according to previous standard.Fracture conductivity is one of the key parameters that affects acid fracturing effects,but it's difficult to be predicted accurately due to the strong randomness of acid-rock reaction as well as various influence factors.Analyses of the impacts on fracture conductivity resulted from the rock embedment intensity,closure stress,acid dosage,rock-acid contact time,acid fluid loss,acid pumping rate through self-developed small-core fracture capacity test instrument.Fluid loss during acid fracture can be well controlled by thickened liquid as well as solid particles,but formation damage occurs inevitably.Foamed acid is a specific fluid with high viscosity,low fluid loss,small friction resistance,good retarding property,strong fracture making ability,easy flowback and low damage,which is an ideal acid system for low pressure and low permeability carbonate reservoirs.In this paper,the theoretical study on percolation mechanism and fluid-loss control mechanism of foam(acid)in porous medium are presented with the help of visual microscopic model fluid drive unit.Nianyin Li Jinxin Dai Pingli Liu Zhifeng Luo Liqiang Zhao 2015Petroleum2015,1,2:5
7Rice caryopsis development Ⅰ: Dynamic changes in different cell layers显示文摘Rice caryopsis as one of the most important food sources for humans has a complex structure that is composed of maternal tissues including the pericarp and testa and filial tissues including the endosperm and embryo. Although rice caryopsis studies have been conducted previously, a systematic characterization throughout the entire developmental process is still lacking. In this study, detailed morphological examinations of caryopses were made during the entire 30-day developmental process. We observed some rapid changes in cell differentiation events and cataloged how cellular degeneration processes occurred in maternal tissues. The differentiations of tube cells and cross cells were achieved by 9 days after pollination(DAP). In the testa, the outer integument was degenerated by 3 DAP, while the outer layer of the inner integument degenerated by 7 DAP. In the nucellus, all tissues with the exception of the nucellar projection and the nucellar epidermis degenerated in the first 5 DAP. By 21 DAP, all maternal tissues, including vascular bundles, the nucellar projection and the nucellar epidermal cells were degenerated. In summary, this study provides a complete atlas of the dynamic changes in cell differentiation and degeneration for individual maternal cell layers of rice caryopsis.Xiaoba Wu Jinxin Liu Dongqi Li Chun-Ming Liu 2016Journal of Integrative Plant Biology2016,58,9:4
8Feasibility study on application of volume acid fracturing technology to tight gas carbonate reservoir development显示文摘How to effectively develop tight-gas carbonate reservoir and achieve high recovery is always a problem for the oil and gas industry.To solve this problem,domestic petroleum engineers use the combination of the successful experiences of North American shale gas pools development by stimulated reservoir volume(SRV)fracturing with the research achievements of Chinese tight gas development by acid fracturing to propose volume acid fracturing technology for fractured tightgas carbonate reservoir,which has achieved a good stimulation effect in the pilot tests.To determine what reservoir conditions are suitable to carry out volume acid fracturing,this paper firstly introduces volume acid fracturing technology by giving the stimulation mechanism and technical ideas,and initially analyzes the feasibility by the comparison of reservoir characteristics of shale gas with tight-gas carbonate.Then,this paper analyzes the validity and limitation of the volume acid fracturing technology via the analyses of control conditions for volume acid fracturing in reservoir fracturing performance,natural fracture,horizontal principal stress difference,orientation of insitu stress and natural fracture,and gives the solution for the limitation.The study results show that the volume acid fracturing process can be used to greatly improve the flow environment of tight-gas carbonate reservoir and increase production;the incremental or stimulation response is closely related with reservoir fracturing performance,the degree of development of natural fracture,the small intersection angle between hydraulic fracture and natural fracture,the large horizontal principal stress difference is easy to form a narrow fracture zone,and it is disadvantageous to create fracture network,but the degradable fiber diversion technology may largely weaken the disadvantage.The practices indicate that the application of volume acid fracturing process to the tight-gas carbonate reservoir development is feasible in the Ordovician Majiagou Formation of lower Paleozoic,which is of great significance and practical value for domestic tight-gas carbonate reservoir development and studies in the future.Nianyin Li Jinxin Dai Chao Liu Pingli Liu Yanming Zhang Zhifeng Luo Liqiang Zhao 2015Petroleum2015,1,3:4
9Enormous enhancement in electrical performance of few-layered MoTe2 due to Schottky barrier reduction induced by ultraviolet ozone treatment显示文摘Doping can improve the band alignment at the metal-semiconductor interface to modify the corresponding Schottky barrier,which is crucial for the realization of high-performance logic components.Here,we systematically investigated a convenient and effective method,ultraviolet ozone treatment,for p-type doping of MoTe2 field-effect transistors to enormously enhance the corresponding electrical performance.The resulted hole concentration and mobility are near 100 times enhanced to be〜1.0×10^13 cm^-2 and 101.4 cm^2/(V·s),respectively,and the conductivity is improved by 5 orders of magnitude.These values are comparable to the highest ones ever obtained via annealing doping or non-lithographic fabrication methods at room temperature.Compared with the pristine one,the photoresponsivity(522 mA/W)is enhanced approximately 100 times.Such excellent performances can be attributed to the sharply reduced Schottky barrier because of the surface charge transfer from MoTe2 to MoOx(x<3),as proved by photoemission spectroscopy.Additionally,the p-doped devices exhibit excellent stability in ambient air.Our findings show significant potential in future nanoelectronic and optoelectronic applications.Xiaoming Zheng Xueao Zhang Yuehua Wei Jinxin Liu Hang Yang Xiangzhe Zhang Shitan Wang Haipeng Xie Chuyun Deng Yongli Gao Han Huang 2020Nano Research2020,13,4:3
10Comprehensively-modified polymer electrolyte membranes with multifunctional PMIA for highly-stable all-solid-state lithium-ion batteries显示文摘Polyethylene oxide(PEO)-based electrolytes have obvious merits such as strong ability to dissolve salts(e.g.,LiTFSI)and high flexibility,but their applications in solid-state batteries is hindered by the low ion conductance and poor mechanical and thermal properties.Herein,poly(m-phenylene isophthalamide)(PMIA)is employed as a multifunctional additive to improve the overall properties of the PEO-based electrolytes.The hydrogen-bond interactions between PMIA and PEO/TFSI-can effectively prevent the PEO crystallization and meanwhile facilitate the LiTFSI dissociation,and thus greatly improve the ionic conductivity(two times that of the pristine electrolyte at room temperature).With the incorporation of the high-strength PMIA with tough amide-benzene backbones,the PMIA/PEO-LiTFSI composite polymer electrolyte(CPE)membranes also show much higher mechanical strength(2.96 MPa),thermostability(4190℃)and interfacial stability against Li dendrites(468 h at 0.10 mA cm-2)than the pristine electrolyte(0.32 MPa,364℃and short circuit after 246 h).Furthermore,the CPE-based LiFePO4/Li cells exhibit superior cycling stability(137 mAh g^-1 with 93%retention after 100 cycles at 0.5 C)and rate performance(123 mAh g^-1 at 1.0 C).This work provides a novel and effective CPE structure design strategy to achieve comprehensively-upgraded electrolytes for promising solid-state battery applications.Lehao Liu Jinshan Mo Jingru Li Jinxin Liu Hejin Yan Jing Lyu Bing Jiang Lihua Chu Meicheng Li 2020Journal of Energy Chemistry2020,29,9:3
11Characteristics of SARS-CoV-2 Delta variant-infected individuals with intermittently positive retest viral RNA after discharge显示文摘SARS-CoV-2-infected patients will be discharged when viral ribonucleic acid(RNA)is consecutively negative at least twice over a 24-h interval.However,we have demonstrated that positive retest viral RNA,a particular clinical phenomenon initially observed in discharged SARS-CoV-2-infected patients in early 2020[1,2],is the occasional reoccurrence of Polymerase Chain Reaction(PCR)-detectable viral RNA but not reinfection[3].Lu Li Jingyan Tang Zhiwei Xie Qingxin Gan Guofang Tang Zhongwei Hu Huimin Zeng Jingrong Shi Jiaojiao Li Yan Li Changwen Ke Min Kang Dan Liang Huan Lu Yuwei Tong Xilong Deng Jinxin Liu Hongzhou Lu Fuxiang Wang Fengyu Hu Feng Li Nanshan Zhong Xiaoping Tang 2022National Science Review2022,9,10:3
12Planning for a Healthy City: The Influence of Built Environment on Elderly's Body Mass Index显示文摘The influence of the built environment on human health has attracted increasing attention. Given that the elderly have been an integral part in China, the built environment not only influences their health, but also influences the life and work of their children, thus resulting in social problems. Based on questionnaire obtained data on the elderly people in Chongqing, an ordinal multi-categorical regression model is established to analyze the influence of built environment on the leisure and physical activities(especially walking) that the elderly participated in, and the influence on their Body Mass Index(BMI). The results show that, in addition to age and preference for high-calorie diet, whether there is convenient access to leisure and fitness places from where they live, and the corresponding distance in-between are significantly related to the BMI of the elderly. Particularly, the best distance range is less than 1,000 m, within which leisure and fitness places have significant impact on the BMI of the elderly and the influence shows distance decay. In the last section of this paper, according to the conclusion, proposals are put forward for the optimization of the built environment.Chen Chun Chen Yong Yu Li Zhou Wei Liu Jinxin 2018China City Planning Review2018,27,1:2
13Research on Urban Carbon Emission Inventory and Its Application in Planning显示文摘This paper systematically reviewed related studies on urban carbon emission inventory, and especially analyzed current studies on the urban greenhouse gas inventory in China. Through comparative studies of four cases, it systematically discusses the application of urban carbon emission inventory in low carbon urban planning as a response to climate change, it thus concluded that city planners in China have duty-bound obligations and responsibilities to apply low carbon ideas into urban and regional planning, and the in-depth study on greenhouse gas emission inventory is undoubtedly of great significance and scientific value to mitigate climate change.Gu Chaolin Liu Jinxin(译) Liang Sisi(校) 2017China City Planning Review2017,26,2:2

15Space-confined growth of metal halide perovskite crystal films显示文摘Metal halide perovskites,as a new generation of optoelectronic materials,have attracted a great deal of interest due to their remarkable intrinsic properties.Due to the excellent optoelectronic properties,the perovskite crystals are widely used in lasers,photodetectors,X-ray detectors and solar cells.Considering the device performance and fabrication requirements,proper thickness of the crystal is required to avoid carrier loss and simultaneously ensure sufficient light absorption,which can realize the full potential of its excellent carrier transport property.Thus,the fabrication of perovskite crystal in a thin film with an adjustable thickness is highly desirable.The space-confined method has been demonstrated to be an effective way of preparing perovskite with controlled thickness.In this method,the thickness of perovskite can be regulated flexibly in a geometric confined space.Moreover,the size,quality and architecture of perovskite crystal films are also major concerns for practical photoelectric devices,which can also be optimized by the space-confined method owing to its good adaptability towards various modified strategies.In a word,the space-confined method is not only a simple and conventional way to adjust the thickness of perovskite crystal films,but also provides a platform to optimize their size,quality and architecture through applying appropriate strategies to the confined space.Herein,we review the space-confined growth of perovskite crystal films.Particularly,various modified strategies based on the space-confined method applied to the optimization of thickness,size,quality and architecture are highlighted.Then the stability investigating and component regulating of perovskite crystal films would be also mentioned.Furthermore,the correlation between the perovskite thickness and the device performance is discussed.Finally,several key challenges and proposed solutions of perovskite thin films based on the space-confined method are discussed.Linyi Li Jinxin Liu Mengqi Zeng Lei Fu 2021Nano Research2021,14,6:2
16Spatial Distribution Characteristics and Influencing Factors of Taobao Villages in Guangzhou显示文摘Through a case study on 24 Taobao villages in Guangzhou,this paper analyzes the relationship between the spatial distribution characteristics and influencing factors of Taobao villages using the online data mining methodology,and compares e-commerce-based industry clusters with traditional industry clusters.The result shows that Taobao villages in Guangzhou are mainly distributed in peripheral areas of the central city,with low population and employment density; villages running the same kind of business present the trend of concentration.And the formation of Taobao villages is highly relevant to the distribution of factories,wholesale markets,express services,and low-rent housing,as well as the learning and demonstration effect among subjects.It further proves that,under the influence of e-commerce,the importance of economies of scale and economies of scope brought by geographic proximity has been weakened,while the importance of interaction and communication effect among subjects have been obviously strengthened.Hu Yao Liu Li Liu Jinxin 2017China City Planning Review2017,26,4:2
17Reflections and Practical Explorations of Rights in Street Design显示文摘Street is the public resource of the city. While the street design is seemingly a technical means for physical space, essentially it is the redistribution of urban space rights. This paper argues that street design should focus on the 'street right,' which can be divided into the right to pass and the right to stay, and it may as well be divided into permanent right and process right. Permanent right mainly includes property right and use right, and process right includes participation right and decision-making right. At present, there are many problems confronted by streets in China, such as uncoordinated division of property right between public and private parties, unfair spatial distribution neglecting the use right of slow traffic, less participation and no decision-making right for citizens during street design process, etc. Based on recent design practices in Shanghai, Xiamen, Shangyu, and several other cities, this paper explores strategies in terms of the coordination and integration of property right and space, fair distribution of street use right, and the public empowerment in street design.Ge Yan Liu Jinxin(译) Liang Sisi(校) 2019China City Planning Review2019,28,3:2
18HY5-HDA9 orchestrates the transcription of HsfA2 to modulate salt stress response in Arabidopsis显示文摘Integration of light signaling and diverse abiotic stress responses contribute to plant survival in a changing environment.Some reports have indicated that light signals contribute a plant’s ability to deal with heat,cold,and stress.However,the molecular link between light signaling and the saltresponse pathways remains unclear.We demonstrate here that increasing light intensity elevates the salt stress tolerance of plants.Depletion of HY5,a key component of light signaling,causes Arabidopsis thaliana to become salinity sensitive.Interestingly,the small heat shock protein(sHsp)family genes are upregulated in hy5-215 mutant plants,and HsfA 2 is commonly involved in the regulation of these sH sps.We found that HY5directly binds to the G-box motifs in the HsfA2promoter,with the cooperation of HISTONE DEACETYLASE 9(HDA9),to repress its expression.Furthermore,the accumulation of HDA9 and the interaction between HY5 and HDA9 are significantly enhanced by salt stress.On the contrary,high temperature triggers HY5 and HDA9 degradation,which leads to dissociation of HY5-HDA9from the HsfA2 promoter,thereby reducing salt tolerance.Under salt and heat stress conditions,fine tuning of protein accumulation and an interaction between HY5 and HDA9 regulate HsfA2 expression.This implies that HY5,HDA9,and HsfA2play important roles in the integration of light signaling with salt stress and heat shock response.Jiaheng Yang Xiao Qu Tao Li Yixiang Gao Haonan Du Lanjie Zheng Manchun Ji Paifeng Zhang Yan Zhang Jinxin Hu Liangyu Liu Zefu Lu Zijian Yang Huiyong Zhang Jianping Yang Yongqing Jiao Xu Zheng 2023Journal of Integrative Plant Biology2023,65,1:1
19Multi-Plan Integration: A Pilot Study of Mianzhu, Sichuan Province显示文摘The current planning system in China lacks coordination, which is a crucial issue to be explored to fully implement the multi-plan integration. Mianzhu is an example that is officially named as one of the pilot cities for multi-plan integration on the county level. The paper firstly analyzes the problems associated with multi-plan integration in Mianzhu, including the indeterminate hierarchy of the planning system, the disunity of technical standards, problems regarding spatial order, coordination and division of powers and functions, and the intensive utilization of spatial resources, the lack of a coordination mechanism, and low participation of experts and the public. Secondly, by learning from Germany's spatial planning, and also practical experiences of pilot cities for multi-plan integration in China, this paper creatively brings in the connotation of multi-plan integration on the county level, and further proposes a power division based on three-level planning system and three kinds of space, the reinforcement of a spatial order, intensive spatial utilization, and a planning coordination mechanism, hoping to provide reference to other cities.Fu Fei Li Yanjin Zhang Yingzi Yang Yi Liu Jinxin 2018China City Planning Review2018,27,2:1
20From Directive to Legislation, from Separation to Integration: Rural Planning Evolution Since the Founding of New China显示文摘Since the founding of new China in 1949, rural development in China has experienced three periods, which have been first the collective economy, second the household contract responsibility system, and third the chronological coordination of the urban and rural. Meanwhile, there are three types of statutory planning that guide rural construction and management in China, i.e., land use planning, land consolidation planning, and village and town planning. This paper summarizes their different characteristics in the three periods respectively. Firstly, the period of the collective economy from 1949 to 1978 is the embryonic stage of rural planning, during which land use planning was just introduced from abroad, while land consolidation planning and village and town planning had not yet been formed. In this period, rural planning had a strong planned economy feature. The following period of the household contract responsibility system from 1978 to 2003 is the growth stage of rural planning, during which all three types of planning developed their independent preparation, regulation, and management systems. In the period of urban and rural coordination from 2003 to the present, there has been a trend towards urban and rural integration and joint development among three types of planning. Based on the rural development history in China since 1949, this paper concludes that the three types of statutory planning have transformed in adapting to China's national conditions toward a more standardized, legislated, and integrated mode.Zhang Yuanyuan Huang Jingnan Wang Guo’en Liu Jinxin(译) Liang Sisi(校) 2019China City Planning Review2019,28,1:1
