| 1 | Toward Wisdom-Evolutionary and Primitive-Concise 6G:A New Paradigm of Semantic Communication Networks显示文摘The sixth generation(6G)mobile networks will reshape the world by offering instant,efficient,and intelligent hyper-connectivity,as envisioned by the previously proposed Ubiquitous-X 6G networks.Such hyper-massive and global connectivity will introduce tremendous challenges into the operation and management of 6G networks,calling for revolutionary theories and technological innovations.To this end,we propose a new route to boost network capabilities toward a wisdom-evolutionary and primitive-concise network(WePCN)vision for the Ubiquitous-X 6G network.In particular,we aim to concretize the evolution path toward the WePCN by first conceiving a new semantic representation framework,namely semantic base,and then establishing an intelligent and efficient semantic communication(IE-SC)network architecture.In the IE-SC architecture,a semantic intelligence plane is employed to interconnect the semantic-empowered physical-bearing layer,network protocol layer,and application-intent layer via semantic information flows.The proposed architecture integrates artificial intelligence and network technologies to enable intelligent interactions among various communication objects in 6G.It features a lower bandwidth requirement,less redundancy,and more accurate intent identification.We also present a brief review of recent advances in semantic communications and highlight potential use cases,complemented by a range of open challenges for 6G. | Ping Zhang Wenjun Xu Hui Gao Kai Niu Xiaodong Xu Xiaoqi Qin Caixia Yuan Zhijin Qin Haitao Zhao Jibo Wei Fangwei Zhang | 2022 | Engineering2022,8,1: | 28 |
| 2 | Malus-metasurface-assisted polarization multiplexing显示文摘Polarization optics plays a pivotal role in diffractive,refractive,and emerging flat optics,and has been widely employed in contemporary optical industries and daily life.Advanced polarization manipulation leads to robust control of the polarization direction of light.Nevertheless,polarization control has been studied largely independent of the phase or intensity of light.Here,we propose and experimentally validate a Malus-metasurface-assisted paradigm to enable simultaneous and independent control of the intensity and phase properties of light simply by polarization modulation.The orientation degeneracy of the classical Malus’s law implies a new degree of freedom and enables us to establish a one-to-many mapping strategy for designing anisotropic plasmonic nanostructures to engineer the Pancharatnam–Berry phase profile,while keeping the continuous intensity modulation unchanged.The proposed Malus metadevice can thus generate a near-field greyscale pattern,and project an independent far-field holographic image using an ultrathin and single-sized metasurface.This concept opens up distinct dimensions for conventional polarization optics,which allows one to merge the functionality of phase manipulation into an amplitudemanipulation-assisted optical component to form a multifunctional nano-optical device without increasing the complexity of the nanostructures.It can empower advanced applications in information multiplexing and encryption,anti-counterfeiting,dual-channel display for virtual/augmented reality,and many other related fields. | Liangui Deng Juan Deng Zhiqiang Guan Jin Tao Yang Chen Yan Yang Daxiao Zhang Jibo Tang Zhongyang Li Zile Li Shaohua Yu Guoxing Zheng Hongxing Xu Cheng-Wei Qiu Shuang Zhang | 2020 | Light(Science & Applications)2020,9,1: | 7 |
| 3 | Uniform corrosion behavior of FeCrAl alloys in borated and lithiated high temperature water显示文摘The uniform corrosion behavior of model FeCrAl alloys as well as commercial Zircaloy-4 as reference material were investigated in 360℃borated and lithiated water.The results reveal that FeCrAl alloys exhibited better corrosion resistance than Zircaloy-4.It is found that the oxide films formed on the FeCrAl alloys are composed of outer Fe_(3)O_(4)layer,inner layer consisting of compact spinel layer and porous spinel layer,and transition layer containing Al-Cr-rich oxides and matrix enriched with Fe°.The spinel oxides in the inner layer are FeFe_(2-x-y-z)Cr_(x)Al_(y)MozO_(4).The corrosion mechanism of FeCrAl alloys in high temperature water is discussed. | Fangqiang Ning Xiang Wang Ying Yang Jibo Tan Ziyu Zhang Dan Jia Xinqiang Wu En-Hou Han | 2021 | Journal of Materials Science & Technology2021,,11: | 6 |
| 4 | Overexpression of Rice Sphingosine-1-Phoshpate Lyase Gene OsSPL1 in Transgenic Tobacco Reduces Salt and Oxidative Stress Tolerance显示文摘Sphingolipids, including sphingosine-1-phosphate (S1P), have been shown to function as signaling mediators to regulate diverse aspects of plant growth, development, and stress response. In this study, we performed functional analysis of a rice (Oryza sativa) S1P lyase gene OsSPL1 in transgenic tobacco plants and explored its possible involvement in abiotic stress response. Overexpression of OsSPL1 in transgenic tobacco resulted in enhanced sensitivity to exogenous abscisic acid (ABA), and decreased tolerance to salt and oxidative stress, when compared with the wild type. Furthermore, the expression levels of some selected stress-related genes in OsSPL1-overexpressing plants were reduced after application of salt or oxidative stress, indicating that the altered responsiveness of stress-related genes may be responsible for the reduced tolerance in OsSPL1-overexpressing tobacco plants under salt and oxidative stress. Our results suggest that rice OsSPL1 plays an important role in abiotic stress responses. | Huijuan Zhang Jing Zhai Jibo Mo Dayong Li Fengming Song | 2012 | Journal of Integrative Plant Biology2012,54,9: | 5 |
| 5 | Groundwater evapotranspiration under psammophilous vegetation covers in the Mu Us Sandy Land, northern China显示文摘Groundwater is a significant component of the hydrological cycle in arid and semi-arid areas. Its evapotranspiration is an important part of the water budget because many plants are groundwater-dependent. To restore the degraded ecosystems, the need is pressing to further our understanding of the groundwater evapotranspiration(ET_g) in arid and semi-arid areas. This study employed the White method to estimate ET_g at four sites in the Mu Us Sandy Land in northern China, and the four sites are covered by Salix psammophila(SP site), Artemisia ordosica(AO site), Poplar alba(PA site), and Carex enervis(CE site), respectively. The depth of groundwater table and the duration of drainage were taken into account in calculating the specific yield(S_y) to improve the accuracy of the ET_g estimats. Our results showed that from late May to early November 2013 the ET_g were 361.87(SP site), 372.53(AO site), 597.86(PA site) and 700.76 mm(CE site), respectively. The estimated ET_g rate was also species-dependent and the descending order of the ET_g rate for the four vegetation was: C. enervis, P. alba, A. ordosica, and S. psammophila. In addition, the depth of groundwater table has an obvious effect on the ET_g rate and the effect varied with the vegetation types. Furthermore, the evapotranspiration for the vegetation solely relying on the water supply from unsaturated layers above the groundwater table was much less than that for the vegetation heavily relying on the water supply from shallow aquifers. | CHENG Donghui DUAN Jibo QIAN Kang QI Lijun Yang Hongbin CHEN Xunhong | 2017 | Journal of Arid Land2017,9,1: | 4 |
| 6 | Distributed geospatial information processing: sharing distributed geospatial resources to support Digital Earth显示文摘This paper introduces a new concept,distributed geospatial information processing(DGIP),which refers to the process of geospatial information residing on computers geographically dispersed and connected through computer networks,and the contribution of DGIP to Digital Earth(DE).The DGIP plays a critical role in integrating the widely distributed geospatial resources to support the DE envisioned to utilise a wide variety of information.This paper addresses this role from three different aspects:1)sharing Earth data,information,and services through geospatial interoperability supported by standardisation of contents and interfaces;2)sharing computing and software resources through a GeoCyberinfrastructure supported by DGIP middleware;and 3)sharing knowledge within and across domains through ontology and semantic searches.Observing the long-term process for the research and development of an operational DE,we discuss and expect some practical contributions of the DGIP to the DE. | Chaowei Yang Wenwen Li Jibo Xie Bin Zhou | 2008 | International Journal of Digital Earth2008,1,3: | 4 |
| 7 | A Joint Feedback Bit and Power Allocation Strategy for Multi-cell Systems over Composite Fading Channels显示文摘This paper addresses the joint Feedback bit allocation(FBA) and Power allocation(PA)problem for a limited feedback coordinated multi-cell transmission system over composite fading channels. The Rayleigh/Lognormal fading channel is considered, and the effects of path loss and the macro-level correlation are also taken into account. A modified performance measure, referred to as the virtual sum rate is adopted to facilitate the analysis. The closed forms of the lower bound on virtual sum rate are derived over uncorrelated and correlated shadowed fading channels. Based on the lower bound, we then formulate an optimization problem of maximizing the virtual sum rate under constraints on the total number of feedback bits per MS and the total transmit power per BS. Considering the tight coupling between the FBA and the PA, we solve the optimization problem by solving an alternating sequence of FBA and PA subproblems using a coordinated ascent searching method. Numerical results show that the proposed strategy can converge in a few iterations and generally yield better performance than the conventional FBA schemes under composite fading channels. | MA Yue WANG Xin WANG Haihong GE Songhu WEI Jibo | 2016 | Chinese Journal of Electronics2016,25,3: | 3 |
| 8 | Network for hypersonic UCAV swarms显示文摘Unmanned combat aerial vehicles(UCAVs)that swarm with both autonomous decision-making and cooperative attacking have been regarded as revolutionary elements of modern warfare.In such a swarm,inter-group connectivity must be ensured in a network to maintain a collective consensus.In recent years,academia and industry have made many efforts to achieve common tactical data link systems and commercial drone networks.However,the existing results have difficulty meeting the needs of cooperative autonomous UCAV swarms with both hypersonic mobility and time sensitivity in severe confrontation scenarios.In this article,we conduct an in-depth investigation of the network used for the hypersonic UCAV swarms,which can be considered as a special form of mobile wireless network.Furthermore,faced with specific functional demands,we summarize the main challenges of designing this dedicated network.In addition,a comprehensive survey of potential solutions for the network design is presented.Lastly,we discuss the possible capabilities of the network given the current forefront of technology,as well as remaining challenges and open issues. | Shixun LUO Zhongshan ZHANG Shuai WANG Shuo ZHANG Jibo DAI Xiangyuan BU Jianping AN | 2020 | Science China(Information Sciences)2020,63,4: | 3 |
| 9 | Model-based approach for available bandwidth prediction in multi-hop wireless networks显示文摘We present a complete and practical analytical model for the IEEE 802.11-based multi-hop wireless networks.The features of our model are that it first takes into account the realistic problems both from the physical and MAC (Media Access Control) layers in multi-hop wireless networks,including packet collisions,neighboring interference,hidden node problems,capture effects,non-ideal channels,non-saturated situations and multi-rate sending scenarios,which makes the analytical results more accurate.Second,it relates the network parameters to the bandwidth requirements of flows and thus is capable of directly analyzing bandwidth-sensitive applications.Third,it provides a 'what-if' analysis,enabling us to predict the performance of the network after a new flow enters.Based on this model,we then present and validate iterative algorithms for end-to-end available bandwidth predictions.With the property of fast convergence and easy realization,these algorithms can give predictive estimates on the change of parameters that will affect the available bandwidth and thus enable us to obtain more accurate available bandwidth information. | ZHAO HaiTao WANG Shah WEI JiBo SONG An LI Ying | 2011 | Science China(Information Sciences)2011,54,9: | 3 |
| 10 | Bismuth-doped glass microsphere lasers显示文摘In this work, a hybrid structure consisting of a multicomponent germanate glass microsphere containing bismuth as a gain medium is proposed and presented. The bismuth-doped germanate glass microspheres were fabricated from a glass fiber tip with no precipitation of the bismuth metal. Coupling with a fiber taper, the bismuth-doped microsphere single-mode laser was observed to lase at around 1305.8 nm using 808 nm excitation. The low threshold of absorbed pump power at 215 μW makes this microlaser appealing for various applications, including tunable lasers for a range of purposes in telecommunication, biomedical, and optical information processing. | ZAIJIN FANG SíLE NIC CHORMAIC SHANYU WANG XIN WANG JIBO YU YUXUAN JIANG JIANRONG QIU PENGFEI WANG | 2017 | Photonics Research2017,5,6: | 2 |
| 11 | Effects of thiosulfate and dissolved oxygen on crevice corrosion of Alloy 690 in high-temperature chloride solution显示文摘The crevice corrosion behavior of Alloy 690 was investigated in high-temperature chloride solution containing different concentrations of thiosulfate(S_(2)O_(3)^(2-)) and dissolved oxygen(DO). The S2O32- inhibited corrosion of Alloy 690 through consuming oxygen in aerated chloride solution. In deaerated chloride solution,the S_(2)O_(3)^(2-) was reduced to S° and S^(2-) and subsequently incorporated into the oxide films, which promoted the pitting corrosion at locations of both TiN inclusions and matrix inside the crevice during the crevice corrosion as well as influenced the composition and thickness of the oxide films. The effect mechanisms of S_(2)O_(3)^(2-) and DO on crevice corrosion in high-temperature chloride solution are discussed. | Fangqiang Ning Jibo Tan Ziyu Zhang Xinqiang Wu Xiang Wang En-Hou Han Wei ke | 2021 | Journal of Materials Science & Technology2021,,7: | 2 |
| 12 | Lactobacillus rhamnosus GG ameliorates DON-induced intestinal damage depending on the enrichment of beneficial bacteria in weaned piglets显示文摘Background: Deoxynivalenol(DON) is one of the most common environmental pollutants that induces intestinal inflammation and microbiota dysbiosis. Lactobacillus rhamnosus GG(LGG) is a probiotic that not only has anti-inflammatory effects, but also shows protective effect on the intestinal barrier. However, it is still unknown whether LGG exerts beneficial effects against DON-induced intestinal damage in piglets. In this work, a total of 36 weaned piglets were randomized to one of four treatment groups for 21 d. The treatment groups were CON(basal diet);LGG(basal diet supplemented with 1.77 × 10^(11)CFU/kg LGG);DON(DON-contaminated diet) and LGG + DON(DON-contaminated diet supplemented with 1.77 × 10^(11)CFU/kg LGG).Result: Supplementation of LGG can enhance growth performance of piglets exposed to DON by improving intestinal barrier function. LGG has a mitigating effect on intestinal inflammation induced by DON exposure, largely through repression of the TLR4/NF-κB signaling pathway. Furthermore, supplementation of LGG increased the relative abundances of beneficial bacteria(e.g., Collinsella, Lactobacillus, Ruminococcus_torques_group and Anaerofustis), and decreased the relative abundances of harmful bacteria(e.g., Parabacteroides and Ruminiclostridium_6), and also promoted the production of SCFAs.Conclusions: LGG ameliorates DON-induced intestinal damage, which may provide theoretical support for the application of LGG to alleviate the adverse effects induced by DON exposure. | Yongsong Bai Kaidi Ma Jibo Li Zhongshuai Ren Jing Zhang Anshan Shan | 2022 | Journal of Animal Science and Biotechnology2022,13,6: | 2 |

| 14 | Utilize cloud computing to support dust storm forecasting显示文摘The simulations and potential forecasting of dust storms are of significant interest to public health and environment sciences.Dust storms have interannual variabilities and are typical disruptive events.The computing platform for a dust storm forecasting operational system should support a disruptive fashion by scaling up to enable high-resolution forecasting and massive public access when dust storms come and scaling down when no dust storm events occur to save energy and costs.With the capability of providing a large,elastic,and virtualized pool of computational resources,cloud computing becomes a new and advantageous computing paradigm to resolve scientific problems traditionally requiring a large-scale and high-performance cluster.This paper examines the viability for cloud computing to support dust storm forecasting.Through a holistic study by systematically comparing cloud computing using Amazon EC2 to traditional high performance computing(HPC)cluster,we find that cloud computing is emerging as a credible solution for(1)supporting dust storm forecasting in spinning off a large group of computing resources in a few minutes to satisfy the disruptive computing requirements of dust storm forecasting,(2)performing high-resolution dust storm forecasting when required,(3)supporting concurrent computing requirements,(4)supporting real dust storm event forecasting for a large geographic domain by using recent dust storm event in Phoniex,05 July 2011 as example,and(5)reducing cost by maintaining low computing support when there is no dust storm events while invoking a large amount of computing resource to perform high-resolution forecasting and responding to large amount of concurrent public accesses. | Qunying Huang Chaowei Yang Karl Benedict Songqing Chen Abdelmounaam Rezgui Jibo Xie | 2013 | International Journal of Digital Earth2013,6,4: | 2 |

| 16 | Towards Wide-Open, Adaptable DCF Implementation for Dynamic Networks显示文摘This work proposes a Field Programmable Gate Array (FPGA)-oriented architecture for the IEEE 802. 11 Distributed Coordination Function (DCF) transceiver. We describe the functional blocks carrying out the Carrier Sense Multiple Accesses with Collision Avoidance (CSMA/CA), develop the interfaces to the application layer and the physical layer, and implement it on FPGA devices by utilizing Very-high-speed-integrated-circuit Hardware Description Language (VHDL). The novelty of our proposal is twofold. Firstly, all MAC parameters (i.e., Max/Min Contention Window, Data Unit Length, Fragmentation Threshold, Retry Limit, etc.) can be directly accessed and programmed from the application layer interface, which is necessary to achieve better network performance in dynamic environments. Secondly, the character based on FPGA makes the proposal more flexible and risk-reduced for the development of DCF-based wireless networks, such as MANETs and software-defined-radio-based cognitive ad hoc networks. | Wang Shan Abdelhakim Hafid Zhao Haitao Huang Shengchun Xieng Chunlin Wei Jibo | 2012 | China Communications2012,9,7: | 2 |
