1LICOM Model Datasets for the CMIP6 Ocean Model Intercomparison Project显示文摘The datasets of two Ocean Model Intercomparison Project(OMIP)simulation experiments from the LASG/IAP Climate Ocean Model,version 3(LICOM3),forced by two different sets of atmospheric surface data,are described in this paper.The experiment forced by CORE-II(Co-ordinated Ocean–Ice Reference Experiments,Phase II)data(1948–2009)is called OMIP1,and that forced by JRA55-do(surface dataset for driving ocean–sea-ice models based on Japanese 55-year atmospheric reanalysis)data(1958–2018)is called OMIP2.First,the improvement of LICOM from CMIP5 to CMIP6 and the configurations of the two experiments are described.Second,the basic performances of the two experiments are validated using the climatological-mean and interannual time scales from observation.We find that the mean states,interannual variabilities,and long-term linear trends can be reproduced well by the two experiments.The differences between the two datasets are also discussed.Finally,the usage of these data is described.These datasets are helpful toward understanding the origin system bias of the fully coupled model.Pengfei LIN Zhipeng YU Hailong LIU Yongqiang YU Yiwen LI Jirong JIANG Wei XUE Kangjun CHEN Qian YANG Bowen ZHAO Jilin WEI Mengrong DING Zhikuo SUN Yaqi WANG Yao MENG Weipeng ZHENG Jinfeng MA 2020Advances in Atmospheric Sciences2020,37,3:9
2KIF2C:a novel link between Wnt/β-catenin and mTORCI signaling in the pathogenesis of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)is the most common primary liver malignancy and is the fourth-leading cause of cancer-related deaths worldwide.HCC is refractory to many standard cancer treatments and the prognosis is often poor,highlighting a pressing need to identify biomarkers of aggressiveness and potential targets for future treatments.Kinesin family member 2C(KIF2C)is reported to be highly expressed in several human tumors.Nevertheless,the molecular mechanisms underlying the role of KIF2C in tumor development and progression have not been investigated.In this study,we found that KIF2C expression was significantly upregulated in HCC,and that KIF2C up-regulation was associated with a poor prognosis.Utilizing both gain and loss of function assays,we showed that KIF2C promoted HCC cell proliferation,migration,invasion,and metastasis both in vitro and in vivo.Mechanistically,we identified TBC1D7 as a binding partner of KIF2C,and this interaction disrupts the formation of the TSC complex,resulting in the enhancement of mammalian target of rapamycin complexl(mTORCI)signal transduction.Additionally,we found that KIF2C is a direct target of the Wnt/β-catenin pathway,and acts as a key factor in mediating the crosstalk between Wnt/β-catenin and mTORCI signaling.Thus,the results of our study establish a link between Wnt/β-catenin and mTORCI signaling,which highlights the potential of KIF2C as a therapeutic target for the treatment of HCC.Shi Wei Miaomiao Dai Chi Zhang Kai Teng Fengwei Wang Hongbo Li Weipeng Sun Zihao Feng Tiebang Kang Xinyuan Guan Ruihua Xu Muyan Cai Dan Xie 2021Protein & Cell2021,12,10:8
3The FGOALS climate system model as a modeling tool for supporting climate sciences:An overview显示文摘Climate system models are useful tools for understanding the interactions among the components of the climate system and predicting/projecting future climate change. The development of climate models has been a central focus of the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics, Chinese Academy of Sciences(LASG/IAP) since the establishment of the laboratory in 1985. In China, many pioneering component models and fully coupled models of the climate system have been developed by LASG/IAP. The fully coupled climate system developed in the recent decade is named FGOALS(Flexible Global Ocean-Atmosphere-Land System Model). In this paper, an application-oriented review of the LASG/IAP FGOALS model is presented. The improved model performances are demonstrated in the context of cloud-radiation processes, Asian monsoon, ENSO phenomena, Atlantic Meridional Overturning Circulation(AMOC) and sea ice. The FGOALS model has contributed to both CMIP5(Coupled Model Intercomparison Project-phase 5) and IPCC(Intergovernmental Panel on Climate Change) AR5(the Fifth Assessment Report). The release of FGOALS data has supported the publication of nearly 500 papers around the world. The results of FGOALS are cited ~106 times in the IPCC WG1(Working Group 1) AR5. In addition to the traditional long-term simulations and projections, near-term decadal climate prediction is a new set of CMIP experiment, progress of LAGS/IAP in the development of nearterm decadal prediction system is reviewed. The FGOALS model has supported many Chinese national-level research projects and contributed to the national climate change assessment report. The crucial role of FGOALS as a modeling tool for supporting climate sciences is highlighted by demonstrating the model's performances in the simulation of the evolution of Earth's climate from the past to the future.TianJun Zhou Bin Wang YongQiang Yu YiMin Liu WeiPeng Zheng LiJuan Li Bo Wu PengFei Lin Zhun Guo WenMin Man Qing Bao AnMin Duan HaiLong Liu XiaoLong Chen Bian He JianDong Li LiWei Zou XiaoCong Wang LiXia Zhang Yong Sun WenXia Zhang 2018Earth and Planetary Physics2018,2,4:6
4Effects of soil nutrients and climate factors on belowground biomass in an alpine meadow in the source region of the Yangtze-Yellow rivers, Tibetan Plateau of China显示文摘Improving our knowledge of the effects of environmental factors(e.g.soil conditions,precipitation and temperature) on belowground biomass in an alpine grassland is essential for understanding the consequences of carbon storage in this biome.The object of this study is to investigate the relative importance of soil nutrients and climate factors on belowground biomass in an alpine meadow in the source region of the Yangtze and Yellow rivers,Tibetan Plateau.Soil organic carbon(SOC),total nitrogen(TN) and total phosphorous(TP) contents and belowground biomass were measured at 22 sampling sites across an alpine meadow on the Tibetan Plateau.We analyzed the data by using the redundancy analysis to determine the main environmental factors affecting the belowground biomass and the contribution of each factor.The results showed that SOC,TN and TP were the main factors that influenced belowground biomass,and the contribution of SOC,TN and TP on biomass was in the range of 47.87%–72.06% at soil depths of 0–30 cm.Moreover,the combined contribution of annual mean temperature(AMT) and mean annual precipitation(MAP) on belowground biomass ranged from 0.92% to 4.10%.A potential mechanism for the differences in belowground biomass was caused by the variations in soil nitrogen and phosphorous,which were coupled with SOC.A significant correlation was observed between MAP and soil nutrients(SOC,TN and TP) at the soil depth of 0–10 cm(P<0.05).We concluded that precipitation is an important driving force in regulating ecosystem functioning as reflected in variations of soil nutrients(SOC,TN and TP) and dynamics of belowground biomass in alpine grassland ecosystems.WANG Haiming SUN Jian LI Weipeng WU Jianbo CHEN Youjun LIU Wenhui 2016Journal of Arid Land2016,8,6:5
5Engineering of dendritic dopant-free hole transport molecules:enabling ultrahigh fill factor in perovskite solar cells with optimized dendron construction显示文摘Developing dopant-free hole-transporting materials(HTMs)for high-performance perovskite solar cells(PVSCs)has been a very active research topic in recent years since HTMs play a critical role in optimizing interfacial charge carrier kinetics and in turn determining device performance.Here,a novel dendritic engineering strategy is first utilized to design HTMs with a D-A type molecular framework,and diphenylamine and/or carbazole is selected as the building block for constructing dendrons.All HTMs show good thermal stability and excellent film morphology,and the key optoelectronic properties could be fine-tuned by varying the dendron structure.Among them,MPA-Cz-BTI and MCz-Cz-BTI exhibit an improved interfacial contact with the perovskite active layer,and non-radiative recombination loss and charge transport loss can be effectively suppressed.Consequently,high power conversion efficiencies(PCEs)of 20.8%and 21.35%are achieved for MPA-Cz-BTI and MCz-Cz-BTI based devices,respectively,accompanied by excellent long-term storage stability.More encouragingly,ultrahigh fill factors of 85.2%and 83.5%are recorded for both devices,which are among the highest values reported to date.This work demonstrates the great potential of dendritic materials as a new type of dopant-free HTMs for high-performance PVSCs with excellent FF.Wei Chen Yang Wang Bin Liu Yajun Gao Ziang Wu Yongqiang Shi Yumin Tang Kun Yang Yujie Zhang Weipeng Sun Xiyuan Feng Frédéric Laquai Han Young Woo Aleksandra B.Djurisic Xugang Guo Zhubing He 2021Science China Chemistry2021,64,1:2
6Clay nanosheet-mediated delivery of recombinant plasmids expressing artificial miRNAs via leaf spray to prevent infection by plant DNA viruses显示文摘Whitefly-transmitted begomoviruses are economically important plant pathogens that cause severe problems in many crop plants,such as tomato,papaya,cotton,and tobacco.Tomato yellow leaf curl virus(TYLCV)is a typical monopartite begomovirus that has been extensively studied,but methods that can efficiently control begomoviruses are still scarce.In this study,we combined artificial microRNA(amiRNA)-mediated silencing technology and clay nanosheetmediated delivery by spraying and developed a method for efficiently preventing TYLCV infection in tomato plants.We designed three amiRNAs that target different regions of TYLCV to silence virus-produced transcripts.Three plant expression vectors expressing pre-amiRNAs were constructed,and recombinant plasmid DNAs(pDNAs)were loaded onto nontoxic and degradable layered double hydroxide(LDH)clay nanosheets.LDH nanosheets containing multiple pDNAs were sprayed onto plant leaves.We found that the designed amiRNAs were significantly accumulated in leaves 7 days after spraying,while the pDNAs were sustainably detected for 35 days after the spray,suggesting that the LDH nanosheets released pDNAs in a sustained manner,protected pDNAs from degradation and efficiently delivered pDNAs into plant cells.Importantly,when the LDH nanosheets coated with pDNAs were sprayed onto plants infected by TYLCV,both the disease severity and TYLCV viral concentration in sprayed plants were significantly decreased during the 35 days,while the levels of H_(2)O_(2) were significantly increased in those plants.Taken together,these results indicate that LDH nanosheets loaded with pDNAs expressing amiRNAs can be a sustainable and promising tool for begomovirus control.Qili Liu Yanpeng Li Kedong Xu Dongxiao Li Haiyan Hu Feng Zhou Puwen Song Yongang Yu Qichao Wei Qian Liu Weipeng Wang Ruifang Bu Haili Sun Xiaohui Wang Jianjun Hao Honglian Li Chengwei Li 2020Horticulture Research2020,7,1:1

13淋巴细胞密度及分布与直肠癌新辅助治疗反应的关系显示文摘背景:研究认为,淋巴细胞密度与直肠癌预后相关;但新辅助治疗前淋巴细胞分布模式对预后的影响尚不清楚。本研究旨在评估淋巴细胞的分布及密度与直肠癌新辅助治疗反应的关系。方法:对前瞻性队列中接受新辅助治疗的134例直肠癌患者进行回顾性分析。对新辅助治疗前活检标本进行免疫组化染色(CD4和CD8)。评估瘤内腺体周围淋巴细胞(IPL)和肿瘤浸润淋巴细胞(TIL)的密度。采用logistic回归模型(包括临床病理特征、分子特征及治疗方案)评估不同淋巴细胞的密度与肿瘤退缩分级(TRG)的关系。结果:CD8^(+)TIL密度高的患者接受新辅助治疗后获得了更佳的TRG(OR=0.23,95%CI:0.07-0.76,P<0.001)。而CD8^(+)IPL(P=0.033)、CD4^(+)IPL(P=0.156)和CD4^(+)TIL(P=0.170)则与TRG无明显相关性。敏感性分析未发现CD8^(+)TIL与新辅助放疗(P_(相互作用)=0.831)或化疗(P_(交互作用)=0.879)对TRG的影响存在交互作用。结论:本研究结果显示,CD8^(+)TIL而不是CD8^(+)IPL,可独立影响直肠癌新辅助治疗反应,这种影响不受放疗或化疗方案的干扰。Sicong Lai Xiaoying Lou Xinjuan Fan Weipeng Sun Yanhong Deng Jianping Wang Yan Huang Ruoxu Dou 2020Gastroenterology Report2020,8,6:1
14Bionic Thermosensation Inspired Temperature Gradient Sensor Based on Covalent Organic Framework Nanofluidic Membrane with Ultrahigh Sensitivity显示文摘The ability to precisely monitor temperature at a high resolution is an important task,particularly in terms of safety.Inspired by natural thermosensitive transient receptor potential cation channels,we developed a temperature sensor based on thermaldriven ionic charge separation.To mimic the function of nature,an ionic covalent organic frameworkbased nanofluidic membrane was fabricated.By engineering the membrane to separate two electrolyte solutions,the temperature difference across the membrane can synchronously induce a potential.The high charge density and narrow channel size render extraordinary permselectivity to the membrane,thus offering a thermosensation selectivity of up to 1.25 mV K^(−1),superior to that of any known natural system.Additionally,the generated potential is linearly related to the introduced temperature gradient,thus allowing for precise detection.With these attributes,an alarm device with high thermosensation sensitivity was constructed,demonstrating great promise for environmental temperature monitoring.Weipeng Xian Pengcheng Zhang Changjia Zhu Xiuhui Zuo Shengqian Ma Qi Sun 2021CCS Chemistry2021,3,11:1
15An epidermal electrode based triboelectric walking energy harvester for wearable wireless sensing applications显示文摘Harvesting bio-kinetic energy using a triboelectric nanogenerator(TENG) is one of the promising routes to solve the sustainable energy supply problem for wearable electronics. However, additional materials, complex fabricating processes or specific mechanical structures are needed for existing TENGs to harvest bio-kinetic energy. Besides, they need to be tightly attached to the human body, which may result in detachment and malfunction under tense human motion. Herein, an intrinsic epidermal electrode-based TENG(E-TENG) is proposed to harvest human walking energy. The wearing shoes and ground are used as tribo-materials, and the human epidermis is used as the back electrode of the E-TENG. Compared with the traditional TENGs,the E-TENG does not need any additional tribo-materials and complex mechanical structures. Under optimal conditions, the voltage output of E-TENG can reach 914 V. E-TENG has been used as a self-powered warning sensor and pedometer sensor for demonstration. Furthermore, E-TENG based self-powered wireless sensor system has been developed using a newly designed micro energy electronic switch(MEES). Ambient ultraviolet intensity, temperature and humidity information can be monitored and then transmitted to mobile phone every 3.5 min, demonstrating great potential for widespread wearable applications.CHANG ShiYuan LIU FuHai CHEN JinKai XIA LianBin ZHOU Hao JIANG JingYang DONG Kang ZHANG ChenHao WU Yun CHEN Jin XUAN Weipeng SUN LingLing JIN Hao DONG ShuRong LUO JiKui 2024Science China(Technological Sciences)2024,67,3:0
16Closed Solution for Initial Post-Buckling Behavior Analysis of a Composite Beam with Shear Deformation Effect显示文摘This paper is focused on the post-buckling behavior of the fixed laminated composite beams with effects of axial compression force and the shear deformation.The analytical solutions are established for the original control equations(that is not simplified)by applying the Maclaurin series expansion,Chebyshev polynomials,the harmonic balance method and the Newton’s method.The validity of the present method is verified via comparing the analytical approximate solutions with the numerical ones which are obtained by the shooting method.The present third analytical approximate solutions can give excellent agreement with the numerical solutions for a wide range of the deformation amplitudes.What’s more,the effect of shear deformation on the post-bucking configuration of the sandwich beam is also proposed.It can be found that the shear angle has a great influence on the post-buckling load of composite beams.Therefore,the model simplifying the shear formation term as small quantity is not accurate for the case of sandwich beam with soft core.Yongping Yu Lihui Chen Shaopeng Zheng Baihui Zeng Weipeng Sun 2020Computer Modeling in Engineering & Sciences2020,,4:0
17Facile preparation of^(177)Lu-microspheres for hepatocellular carcinoma radioisotope therapy显示文摘As one of the most common cancers in the world,hepatocellular carcinoma(HCC)has become a major threat to human health.Radioembolization is a first-line option for the treatment of HCC,especially when other conventional treatments fail or there exist some relative contraindications.Herein,we developed a facile and efficient method for preparing ^(177)Lu-microspheres potentially useful for precise radioembolization therapy of HCC.The radiolabeling efficiency of ^(177)Lu-microspheres was as high as 96.8%±0.5%,and the radiolabeling process did not alter the morphology of the mother microspheres.The SPECT/CT studies enabled by the unique emissions of ^(177)Lu suggested that almost no ^(177)Lu ion loaded by the microspheres was released over more than 32 d in vivo,which led to remarkable inhibition effect on the growth of HepG2 tumors subcutaneously transplanted in mice.The current approach may thus offer promising ^(177)Lu-microspheres for clinical radioembolization of HCC.Manran Wu Kexin Shi Ruizhe Huang Chunyi Liu Lingling Yin Weipeng Yong Jing Sun Guanglin Wang Zhiyuan Zhong Mingyuan Gao 2022Chinese Chemical Letters2022,33,7:0

19Analytical and experimental study of a valveless piezoelectric micropump with high flowrate and pressure load显示文摘Miniaturized gas pumps based on electromagnetic effect have been intensively studied and widely applied in industries.However,the electromagnetic effect-based gas pumps normally have large sizes,high levels of noises and high power consumption,thus they are not suitable for wearable/portable applications.Herein,we propose a high-flowrate and high-pressure load valveless piezoelectric micropump with dimensions of 16 mm*16 mm*5 mm.The working frequency,vibration mode and displacement of the piezoelectric actuator,the velocity of gas flow,and the volume flowrate of the micropump are analyzed using the finite element analysis method.The maximum vibration amplitude of the piezoelectric actuator reaches~29.4μm.The output gas flowrate of the pump is approximately 135 mL/min,and the maximum output pressure exceeds 40 kPa.Then,a prototype of the piezoelectric micropump is fabricated.Results show that performance of the micropump is highly consistent with the numerical analysis with a high flowrate and pressure load,demonstrated its great potential for wearable/portable applications,especially for blood pressure monitoring.Jiafeng Ni Weipeng Xuan Yilin Li Jinkai Chen Wenjun Li Zhen Cao Shurong Dong Hao Jin Lingling Sun Jikui Luo 2023Microsystems & Nanoengineering2023,9,3:0
