| 1 | The impact of biofuel plantation on biodiversity: a review显示文摘Because plants convert solar energy into chemical energy stored in organisms, biomass production as an energy source can help to reduce the world's reliance on fossil energy and mitigate global warming. Biofuel production is a fast-growing industry that represents a new type of large-scale human disturbance on ecosystems. Thus, the benefits of biofuel production bring environmental risks that include its potential impact on biodiversity, which is still an open question. In this review, we start first with a brief overview of the evolution of biofuel concept; second, we review the state of biofuel production across the continents,with a major emphasis on the main species used and their major feedstock. For which, we found significant differences for land use and environmental cultural management of biofuel plantation between tropical and temperate regions.Third, we summarize the impacts of biofuel plantation on biodiversity at multiple scales, based on the case studied with respect to the corresponding issues. At the genetic level,introgression and contamination by aggressive genotypes are a primary risk. At the species level, habitat pollution, degradation, and disturbance caused by intensive managementof biofuel plantation significantly raise the risk of habitat fragmentation, native extinction, and bio-invasion. At the ecosystem level, the large-scale homogeneous landscape of biofuel plantation results in simplified community and food web that severely damage ecosystem services, including ecosystem diversity. Finally, we compare the current and potential benefits and risks of biofuel plantations for the practical application of a biofuel industry of China. We emphasize the land use constraint from food security and biodiversity conservation, and the need for scientific research and systematic monitoring as a critical support for the sustainable development of biofuel production in China. | Ye Liu Yue Xu Fengchun Zhang Jinqi Yun Zehao Shen | 2014 | Chinese Science Bulletin2014，59，34： | 2 |
| 2 | Adaptive neural network based boundary control of a flexible marine riser system with output constraints显示文摘In this study,we develop an adaptive neural network based boundary control method for a flexible marine riser system with unknown nonlinear disturbances and output constraints to suppress vibrations.We begin with describing the dynamic behavior of the riser system using a distributed parameter system with partial differential equations.To compensate for the effect of nonlinear disturbances,we construct a neural network based boundary controller using a radial basis neural network to reduce vibrations.Under the proposed boundary controller,the state of the riser is guaranteed to be uniformly bounded based on the Lyapunov method.The proposed methodology provides a way to integrate neural networks into boundary control for other flexible robotic manipulator systems.Finally,numerical simulations are given to demonstrate the effectiveness of the proposed control method. | Chuyang YU Xuyang LOU Yifei MA Qian YE Jinqi ZHANG | 2022 | Frontiers of Information Technology & Electronic Engineering2022，23，8： | 1 |
| 3 | An intravascular needle coated by ZnO nanoflowers for in vivo elimination of circulating tumor cells显示文摘Circulating tumor cells(CTCs)are recognized as the main source of tumor recurrence and metastasis.Eliminating the CTCs in peripheral blood provides a new strategy to reduce the probability of recurrence or metastasis.Here,we proposed a concept to eliminate CTCs by inserting a needle in the superficial blood vessel.Using the property of ZnO and the structure of nanoflowers,we designed a medical needle coated with ZnO nanoflowers(ZNFs),which killed about 90%of captured CTCs in vitro and prevented the injecting CTCs from spreading to lung tissue in BABL/c mouse model.Results in vitro and in vivo demonstrated that the CTCs not only were captured and killed,but also detached from the needle surface after dead,enabling the ZNFs needle continually eliminate CTCs.Furthermore,a theoretical model was presented to explain the penetration mechanism of cells by nanostructures,which indicated that nanoflowers structure can puncture CTCs more easily than vertical nanowire structure.The concept of inserting an intravascular needle provides a potential strategy to lower the concentration of CTCs in blood and reduce the probability of tumor recurrence or metastasis. | Jinqi Li Xinlei Li Yangfeng Zhang Kun Jin Ye Yuan Ruiqi Ming Yuhua Yang Tongsheng Chen | 2023 | Nano Research2023，16，1： | 0 |
