| 2 | Broadband cross-circular polarization carpet cloaking based on a phase change material metasurface in the mid-infrared region显示文摘In view of the fact that most invisibility devices focus on linear polarization cloaking and that the characteristics of mid-infrared cloaking are rarely studied,we propose a cross-circularly polarized invisibility carpet cloaking device in the mid-infrared band.Based on the Pancharatnam–Berry phase principle,the unit cells with the cross-circular polarization gradient phase were carefully designed and constructed into a metasurface.In order to achieve tunable cross-circular polarization carpet cloaks,a phase change material is introduced into the design of the unit structure.When the phase change material is in amorphous and crystalline states,the proposed metasurface unit cells can achieve highefficiency cross-polarization conversion,and reflection intensity can be tuned.According to the phase compensation principle of carpet cloaking,we construct a metasurface cloaking device with a phase gradient using the designed unit structure.From the near-and far-field distributions,the cross-circular polarization cloaking property is confirmed in the broadband wavelength range of 9.3–11.4μm.The proposed cloaking device can effectively resist detection of cross-circular polarization. | Bo Fang Dantian Feng Peng Chen Lijiang Shi Jinhui Cai Jianmin Li Chenxia Li Zhi Hong Xufeng Jing | 2022 | Frontiers of physics2022，17，5： | 1 |
| 3 | Effects of Different Fumigant Preservatives on Antioxidant Capacity of‘Kyoho’Grapes显示文摘With‘Kyoho’grapes as the experimental material,the effects of different concentrations of chlorine dioxide(5,10 and 15 mg/L)and ozone(30,60and 90 mg/m^(3))fumigation on the contents of total phenols,proanthocyanidins and malondialdehyde(MDA)and the activity of polyphenol oxidase(PPO),peroxidase(POD),catalase(CAT)and superoxide dismutase(SOD)in the grapes during low temperature storage were compared and analyzed,hoping to provide reference for the storage and preservation of‘Kyoho’grapes after harvest.The results showed that compared with the control,certain concentrations of fumigant preservatives inhibited the degradation of total phenols and proanthocyanidins in‘Kyoho’grapes to varying degrees,maintained better cell membrane integrity,and inhibited the increase of MDA content and PPO activity,and in the later stage,more stable POD and higher activity of CAT and SOD were maintained.Comprehensive analysis showed that among the six fumigation treatments,10 mg/L ClO_(2)and 60 mg/m^(3)O_(3)could delay the aging process of grapes and maintain better antioxidant capacity and storage quality. | Shuze LIU Huiqin DAI Nan WANG Cheng WANG Zhe SUN Feng ZHANG Chenxia LIU Yongjin QIAO Airong SHEN | 2022 | Agricultural Biotechnology2022，11，3： | 0 |
| 4 | The simple two-step polydimethylsiloxane transferring process for high aspect ratio microstructures显示文摘High aspect ratio units are necessary parts of complex microstructures in microfluidic devices. Some methods that are available to achieve a high aspect ratio require expensive materials or complex chemical processes; for other methods it is difficult to reach simple high aspect ratio structures, which need supporting structures. The paper presents a simple and cheap two-step Polydimethylsioxane(PDMS) transferring process to get high aspect ratio single pillars, which only requires covering the PDMS mold with a Brij@52 surface solution after getting a relative PDMS mold based on an SU8 mold. The experimental results demonstrate the method efficiency and effectiveness. | Shaoxi Wang Dan Feng Chenxia Hu P.Rezai | 2018 | Journal of Semiconductors2018，39，8： | 0 |
| 5 | Precipitation is the dominant driver for bird species richness,phylogenetic and functional structure in university campuses in northern China显示文摘Background:Although urbanization is threatening biodiversity worldwide,the increasing green urban spaces could harbor relatively high biodiversity.Therefore,how to maintain the biodiversity in urban ecosystem is crucial for sustainable urban planning and management,especially in arid and semiarid regions with relatively fragile environment and low biodiversity.Here,for the first time we linked species richness,phylogenetic and functional structure of bird assemblages in university campuses in northern China with plant species richness,glacial-interglacial climate change,contemporary climate,and anthropogenic factors to compare their relative roles in shaping urban bird diversity.Methods:Bird surveys were conducted in 20 university campuses across Inner Mongolia,China.Ordinary least squares models and simultaneous autoregressive models were used to assess the relationships between bird species richness,phylogenetic and functional structure with environmental factors.Structural equation models were used to capture the direct and indirect effects of these factors on the three components of bird diversity.Results:Single-variable simultaneous autoregressive models showed that mean annual precipitation was consistently a significant driver for bird species richness,phylogenetic and functional structure.Meanwhile,mean annual temperature and plant species richness were also significant predictors for bird species richness.Conclusions:This study suggests that campuses with warmer and wetter climate as well as more woody plant species could harbor more bird species.In addition,wetter campuses tended to sustain over-dispersed phylogenetic and functional structure.Our findings emphasize the dominant effect of precipitation on bird diversity distribution in this arid and semiarid region,even in the urban ecosystem. | Chenxia Liang Jun Liu Bin Pan Na Wang Jie Yang Guisheng Yang Gang Feng | 2020 | Avian Research2020，11，3： | 0 |
| 6 | 青藏高原东缘汶川地震断层陡坎类型与级联破裂模型(英文)显示文摘The post-earthquake field investigations reveal that the MW7.9 Wenchuan earthquake of 12th May 2008 ruptured three NE-striking imbricate reverse faults and another NW-trending reverse fault, along the middle Longmenshan fold-and-thrust belt at the eastern margin of the Tibetan plateau. The fault-scarp features can be categorized into eight groups: simple thrust scarp, hanging-wall collapse scarp, simple pressure ridge, dextral pressure ridge, fault-related fold scarp, back-thrust pressure ridge, local normal fault scarp and crocodile-mouth-like scarp. The local normal scarp is first discovered in the reverse-faulting earthquakes as ever reported in the world. Field observation indicates that the Wenchuan earthquake surface rupture is dominated by reverse faulting with a minus right-lateral component, but the relative ratio varies from site to site. Also, the surface ruptures can be divided, for the first order, into two segments, the Yingxiu and Beichuan segments, corresponding to MW7.8 and MW7.57 events, respectively. The two segments further can be divided, for the second order, into four sub-segments in total, which are equivalent to four sub-events of MW7.46, MW7.69, MW6.99 and MW7.52, respectively. The fault segmentation, for different orders, shows a cascade-rupturing pattern and can explain why the quake time of the Wenchuan earthquake was so long as up to 100 second. Aftershock focal mechanisms are also used to constrain the fault geometry for the sub-segments, indicating that the seismogenic faults are listric at depth and in general, the fault plane becomes steeper northward, which enables the fault to accommodate larger strike-slip motion. This earthquake also confirms that the crustal shortening across the Longmenshan fold-and-thrust belt should be responsible for the growth of high topographic relief along the eastern margin of the Tibetan Plateau. | Guihua Yu 徐锡伟 Yann Klinger Guilin Diao Guihua Chen Xiangdong Feng Chenxia Li , Ailan Zhu Renmao Yuan Tingting Guo Xinze Sun Xibin Tan Yanfeng An | 2010 | 国际地震动态2010，，6： | 0 |
