| 1 | Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears. | Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG | 2021 | Science China(Information Sciences)2021，64，1： | 122 |
| 2 | A new criterion of coal burst proneness based on the residual elastic energy index显示文摘To evaluate the coal burst proneness more precisely,a new energy criterion namely the residual elastic energy index was proposed.This study begins by performing the single-cyclic loading-unloading uniaxial compression tests with five pre-peak unloading stress levels to explore the energy storage characteristics of coal.Five types of coals from different mines were tested,and the instantaneous destruction process of the coal specimens under compression loading was recorded using a high speed camera.The results showed a linear relationship between the elastic strain energy density and input energy density,which confirms the linear energy storage law of coal.Based on this linear energy storage law,the peak elastic strain energy density of each coal specimen was obtained precisely.Subsequently,a new energy criterion of coal burst proneness was established,which was called the residual elastic energy index(defined as the difference between the peak elastic strain energy density and post peak failure energy density).Considering the destruction process and actual failure characteristics of coal specimens,the accuracy of evaluating coal burst proneness based on the residual elastic energy index was examined.The results indicated that the residual elastic energy index enables reliable and precise evaluations of the coal burst proneness. | Fengqiang Gong Yunliang Wang Zhiguo Wang Junfeng Pan Song Luo | 2021 | International Journal of Mining Science and Technology2021，31，4： | 16 |
| 3 | Xuebijing injection alleviates liver injury by inhibiting secretory function of Kupffer cells in heat stroke rats显示文摘OBJECTIVE:To evaluate the effects of Xuebijing(XBJ) injection in heat stroke(HS) rats and to investigate the mechanisms underlying these effects.METHODS:Sixty anesthetized rats were randomized into three groups and intravenously injected twice daily for 3 days with 4 mL XBJ(XBJ group) or phosphate buffered saline(HS and Sham groups) per kg body weight.HS was initiated in the HS and XBJ groups by placing rats in a simulated climate chamber(ambient temperature 40 ℃,humidity 60%).Rectal temperature,aterial pressure,and heart rate were monitored and recorded.Time to HS onset and survival were determined,and serum concentrations of tumor necrosis factor(TNF)-α,inRESULTS:Time to HS onset and survival were significantly longer in the XBJ than in the HS group.Moreover,the concentrations of TNF-α,IL-1β,IL-6,ALT and AST were lower and liver injury was milder in the XBJ than in the HS group.Heat-stress induced structural changes in KCs and hepatic cells were more severe in the HS than in the XBJ group and the concentrations of TNF-α,IL-β and IL-6 secreted by KCs were lower in the XBJ than in the HS group.CONCLUSION:XBJ can alleviate HS-induced systemic inflammatory response syndrome and liver injury in rats,and improve outcomes.These protective effects may be due to the ability of XBJ to inhibit cytokine secretion by KCs. | Yi Chen Huasheng Tong Xingqin Zhang Liqun Tang Zhiguo Pan Zhifeng Liu Pengkai Duan Lei Su | 2013 | Journal of Traditional Chinese Medicine2013，33，2： | 14 |
| 4 | The maternally expressed polycomb group gene OsEMF2a is essential for endosperm cellularization and imprinting in rice显示文摘Cellularization is a key event in endosperm development.Polycomb group(PcG)genes,such as Fertilization-Independent Seed 2(FIS2),are vital for the syncytium-to-cellularization transition in Arabidopsis plants.In this study,we found that OsEMF2a,a rice homolog of the Arabidopsis PcG gene Embryonic Flower2(EMF2),plays a role similar to that of FIS2 in regard to seed development,although there is limited sequence similarity between the genes.Delayed cellularization was observed in osemf2a,associated with an unusual activation of type I MADS-box genes.The cell cycle was persistently activated in osemf2a caryopses,which was likely caused by cytokinin overproduction.However,the overaccumulation of auxin was not found to be associated with the delayed cellularization.As OsEMF2a is a maternally expressed gene in the endosperm,a paternally inherited functional allele was unable to recover the maternal defects of OsEMF2a.Many imprinted rice genes were deregulated in the defective hybrid seeds of osemf2a(♀)/9311(♂)(m9).The paternal expression bias of some paternally expressed genes was disrupted in m9 due to either the activation of maternal alleles or the repression of paternal alleles.These findings suggest that OsEMF2a-PRC2-mediated H3K27me3 is necessary for endosperm cellularization and genomic imprinting in rice. | Xiaojun Cheng Meiyao Pan Zhiguo E Yong Zhou Baixiao Niu Chen Chen | 2021 | Plant Communications2021，2，1： | 5 |
| 5 | Bevacizumab biosimilar LY01008 compared with bevacizumab(Avastin)as first-line treatment for Chinese patients with unresectable,metastatic,or recurrent non-squamous non-small-cell lung cancer:A multicenter,randomized,double-blinded,phase Ⅲ trial显示文摘Background:Previous studies have demonstrated the preclinical pharmacological and toxicological consistency,and clinical pharmacokinetic equivalence of bevacizumab biosimilar LY01008 with reference bevacizumab(Avastin).This randomized controlled trial aimed to compare the efficacy and safety of LY01008 with Avastin in first-line treatment of Chinese patients with advanced or recurrent non-squamous non-small cell lung cancer(NSCLC).Methods:StageⅢB-ⅣNSCLC patients with evaluable lesions,good physical status,and adequate organ functions from 67 centers across China were randomized in a ratio of 1:1 to receive LY01008 or Avastin 15 mg/kg intravenously in combination with paclitaxel/carboplatin(combined treatment)for 4-6 cycles,followed by maintenance monotherapy with LY01008 until disease progression,intolerable toxicity,or death.The primary endpoint was objective response rate(ORR)in accordance with Response Evaluation Criteria in Solid Tumors(RECIST)version 1.1 confirmed by independent radiological review committees(IRRC).Secondary endpoints included disease control rate(DCR),duration of response(DoR),progression-free survival(PFS),overall survival(OS),and safety.This study was registered in Clinical Trials.gov(NCT03533127).Results:Between December 15^(th),2017,and May 15^(th),2019,a total of 649 patients were randomized to the LY01008(n=324)or Avastin(n=325)group.As of September 25th,2019 for primary endpoint analysis,589 patients received ORR evaluation,with a median number of combined treatment cycles of 5(range 1-6)andmedian duration of treatment of 3.0(range 0.0-5.1)months.ORRof responseevaluable patients in the LY01008 and Avastin groups were 48.5% and 53.0%,respectively.The stratified ORR ratio was 0.91(90%CI 0.80-1.04,within the prespecified equivalence margin of 0.75-1.33).Up to May 15^(th),2020,with a median follow-up of 13.6(range 0.8-28.4)months,no notable differences in DCR,median DoR,median PFS,median OS,and 1-year OS rate were observed between the LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,or recurrent non-squamous NSCLC patients in the first-line setting. | Yuankai Shi Kaijian Lei Yuming Jia Bingqiang Ni Zhiyong He Minghong Bi Xicheng Wang Jianhua Shi Ming Zhou Qian Sun Guolei Wang Dongji Chen Yongqian Shu Lianke Liu Zhongliang Guo Yong Liu Junquan Yang Ke Wang Ke Xiao LinWu Tienan Yi Debin Sun Mafei Kang Tianjiang Ma Yimin Mao Jinsheng Shi Tiegang Tang Yan Wang Puyuan Xing Dongqing Lv Wangjun Liao Zhiguo Luo Bin Wang Xiaohong Wu Xiaoli Zhu Shuhua Han Qisen Guo Rongyu Liu Zhiwei Lu Jianyong Zhang Jian Fang Changlu Hu Yinghua Ji Guolong Liu Hong Lu Dedong Wu Junhong Zhang Shuyang Zhu Zheng Liu Wensheng Qiu Feng Ye Yan Yu Yanqiu Zhao Qinhong Zheng Jun Chen Zhanyu Pan Yiping Zhang Wenjuan Lian Bo Jiang Bo Qiu Guojun Zhang Hua Zhang Yanju Chen Yuan Chen Hongbing Duan Manxiang Li Shengming Liu Lijun Ma Hongming Pan Xia Yuan Xueli Yuan Yulong Zheng Emei Gao Li Zhao Shumin Wang Can Wu | 2021 | Cancer Communications2021，41，9： | 5 |

| 13 | Soil fauna diversity at different stages of reed restoration in a lakeshore wetland at Lake Taihu,China显示文摘Introduction:Wetland soil fauna support material cycling and restoration processes in wetland ecosystems.In our study,we observed variations in wetland soil fauna on the shores of Lake Taihu,China.We examined the relationships between fauna and major environmental factors,and looked at the short-and long-term changes in reed wetlands under restoration and in the natural reed lakeshore.Outcomes:We identified 93 groups of soil fauna in different wetlands and found significant differences in the lakeshore wetlands’soil fauna assemblages,depending on the length of the restoration period.By analyzing the soil fauna community evenness,dominance,number of taxa,and diversity,we found minimal seasonal variation in the soil fauna community diversity and abundance.The abundance of soil fauna in the sites under restoration decreased with depth below the soil surface.The reed restoration was obvious in the succession of the soil fauna groups in the long-term site.Although the restoration had an overall positive long-term effect on the soil fauna communities,there were no obvious short-term changes in the number of individuals.Conclusion:The study explored various potential measures to restore soil fauna in the Lake Taihu wetland and developed a theoretical basis for restoring the lakeshore wetland ecosystem. | Wei Li Zhiguo Dou Lijuan Cui Xinsheng Zhao Manyin Zhang Yan Zhang Changjun Gao Zheng Yang Yinru Lei Xu Pan | 2020 | Ecosystem Health and Sustainability2020，6，1： | 1 |
| 14 | Fluid Mobility Evaluation of Tight Sandstones in Chang 7 Member of Yanchang Formation, Ordos Basin显示文摘Fluid mobility has been important topic for unconventional reservoir evaluation.The tight sandstones in Chang 7 Member of the Ordos Basin has been selected to investigate the fluid mobility based on the application of core flooding-NMR combined method and core centrifugation-NMR combined method,and the porous structure is studied using optical microscope,field emission scanning electron microscope(FE-SEM),CT and mercury injection.Our results include:(i)Feldsparrock fragments dissolution pores,calcite dissolution pores,clay mineral dissolution pores,intergranular dissolution expansion pores,inter-granular pores,intra-kaolinite pores,and intra-illite/smectite mixed layer pores are developed in Chang 7 tight sandstones;3D CT pore structure shows that the pore connectivity is positively related to physical properties,and the overall storage space is connected by the throat with diameter between 0.2 and 0.3μm.The percentage of storage space connected by throats with diameter less than 100 nm can reach more than 35%.(ii)Movable fluid saturation of Chang 7 tight sandstones is between 10%and 70%,and movable oil saturation is between 10%and 50%.Movable fluid saturation may cause misunderstanding when used to evaluate fluid mobility,so it is recommended to use movable fluid porosity in the evaluation of fluid mobility.The porosity ranging from 5%to 8%is the inflection point of the fluidity and pore structure.For samples with porosity less than 8%,the movable fluid porosity is generally less than 5%.Moreover,the movable fluid is mainly concentrated in the storage space with a throat diameter of 0.1 to 1μm.For samples with porosity greater than 8%,the porosity of the movable fluid is more than 5%,and the movable fluid is mainly concentrated in the storage space with a throat diameter of 0.2 to 2μm.(iii)The movable fluid saturation measured by core flooding-NMR combined method is generally higher than that measured by core centrifugation-NMR combined method.The former can evaluate the mobility of the oil-water two-phase fluid in samples,while the latter can better reflect the pore structure and directly evaluate the movable fluid in the pore system controlled by different throat diameters.All these results will provide valuable reference for fluid mobility evaluation in tight reservoirs. | Songtao Wu Shixiang Li Xuanjun Yuan Zhi Yang Aifen Li Jingwei Cui Songqi Pan Zhiguo Mao Ling Su You Zhou | 2021 | Journal of Earth Science2021，32，4： | 1 |
| 15 | Preventing inhomogeneous elemental distribution and phase segregation in mixed Pb-Sn inorganic perovskites via incorporating PbS quantum dots显示文摘Inhomogeneous Pb/Sn elemental distribution and the resulted phase segregation in mixed Pb-Sn halide perovskites would result in energy disorder(band structure and phase distribution disorder),which greatly limits their photovoltaic performance.Here,Pb S quantum dot has been synthesized and demonstrated as seeds for modulation crystallization dynamics of the mixed Pb-Sn inorganic perovskites,allowing an enhanced film quality and significantly suppressing phase segregation.With this additive power conversion efficiency of 8%and 6%is obtained under irradiation of full sunlight in planar and mesoporous structured solar cells in combination with CsPb_(0.5) Sn_(0.5)I_(2)Br inorganic perovskite,respectively.Our finding reveals exploring the actual Pb/Sn atoms location in perovskite structure and its influence on developing efficient and stable low-bandgap perovskite solar cells. | Tao Zhang Huaxia Ban Qiang Sun Han Pan Haixuan Yu Zhiguo Zhang Xiaoli Zhang Yan Shen Mingkui Wang | 2022 | Journal of Energy Chemistry2022，31，2： | 1 |

| 19 | CuO nanoflowers/copper fiber felt integrated porous electrode for lithium-ion batteries显示文摘The structure of current collectors has significant effects on the performance of a lithium-ion battery(LIB).In this study,we use copper fiber felts made by multi-tooth cutting and high-temperature solid-phase sintering as the current collector for LIBs.An integrated porous electrode based on CuO nanoflowers/copper fiber felt is developed for the anode.Results suggest that the reversible capacity and cycle stability of this new anode are significantly improved,compared with the pristine bare-surface copper plate under the same condition of rate cycles.The new anode structure based on the copper-fiber felt with a porosity of 60%exhibits a higher performance with an initial specific capacity of 609.5 mAh g^(-1)and retains 486.1 mAh g^(-1)after 200 cycles at a current density of 0.5 C.The improved electrochemical performance of this electrode is attributed to its large surface area of CuO nanoflowers and porous structure of the copper fiber felt,due to enhanced contact between the active material of CuO nanoflowers and electrolyte.This pore-rich structure makes the electrolyte easy to permeate into the electrode,shortens the diffusion path of Li^(+),reduces the internal resistance and alleviates the volume expansion of the active material during the insertion and desertion processes of Li^(+). | YUAN Wei YE YinTong YANG Yang ZHANG XiaoQing PAN BaoYou PENG ZiMing WU MuLun QIU ZhiQiang WANG Chun YUAN YuHang YAN ZhiGuo TANG Yong | 2020 | Science China(Technological Sciences)2020，63，11： | 1 |
