| 2 | A new discovery of macroscopic fossils from the Ediacaran Doushantuo Formation in the Yangtze Gorges area显示文摘Two new horizons with macroscopic fossils are reported in the Doushantuo Formation, Ediacaran System, from the Yangtze Gorges area. The fossils were discovered in the lower and middle black shales of the Doushantuo Formation in the new section at Sandouping Town, Zigui County, Hubei Province. The new macroscopic assemblages in- clude Chuaria and Tawuia, and occur below the well- known ”Miaohe Biota”. These fossils indicate that after the Nantuo ice age, macroscopic multicellular organisms gradually increased in abundance and diversity. Simple, discoidal carbonaceous compres- sions such as chuarids are present in the initial macrofossil assemblage of the Doushantuo Stage. This assemblage was eventually replaceded by the more diverse Miaohe macrofossils, including unam- biguously branching forms, in the uppermost Dou- shantuo Formation. The new discovery of carbona- ceous compression macrofossils from the Doushan- tuo Formation in the Yangtze Gorges area provides new evidence for the correlation of late Neoprotero- zoic successions in southern China. | TANG Feng YIN Chongyu Bengtson Stefan LIU Yongqing WANG Ziqiang LIU Pengju GAO Linzhi | 2006 | Chinese Science Bulletin2006,51,12: | 23 |

| 4 | Trust Access Authentication in Vehicular Network Based on Blockchain显示文摘Data sharing and privacy securing present extensive opportunities and challenges in vehicular network.This paper introducestrust access authentication scheme’as a mechanism to achieve real-time monitoring and promote collaborative sharing for vehicles.Blockchain,which can provide secure authentication and protected privacy,is a crucial technology.However,traditional cloud computing performs poorly in supplying low-latency and fast-response services for moving vehicles.In this situation,edge computing enabled Blockchain network appeals to be a promising method,where moving vehicles can access storage or computing resource and get authenticated from Blockchain edge nodes directly.In this paper,a hierarchical architecture is proposed consist of vehicular network layer,Blockchain edge layer and Blockchain network layer.Through a authentication mechanism adopting digital signature algorithm,it achieves trusted authentication and ensures valid verification.Moreover,a caching scheme based on many-to-many matching is proposed to minimize average delivery delay of vehicles.Simulation results prove that the proposed caching scheme has a better performance than existing schemes based on central-ized model or edge caching strategy in terms of hit ratio and average delay. | Shaoyong Guo Xing Hu Ziqiang Zhou Xinyan Wang Feng Qi Lifang Gao | 2019 | China Communications2019,16,6: | 10 |
| 5 | A new free-hand pedicle screw placement technique with reference to the supraspinal ligament显示文摘We sought to compare the safety and accuracy of a new free-hand pedicle screw placement technique to that of the conventional technique.One hundred fifty-three consecutive adult patients with simple fracture in the thoracic or/and lumbar spine were alternately assigned to either the new free-hand or the conventional group.In the new free-hand technique group,preoperative computerized tomography(CT) images were used to calculate the targeted medial-lateral angle of each pedicle trajectory and the pedicle screw was inserted perpendicular to the corresponding supraspinal ligament.In the conventional technique group,the medial-lateral and cranial-caudal angle of each pedicle trajectory was determined by intraoperatively under fluoroscopic guidance.The accuracy rate of pedicle screw placement,the time of intraoperative fluoroscopy,the operating time and the amount of blood loss during operation were respectively compared.All screws were analyzed by using intraoperative radiographs,intraoperative triggered electromyography(EMG) monitoring data,postoperative CT data and clinical outcomes.The accuracy rate of pedicle screw placement in the new free-hand technique group and the conventional technique group was 96.3% and 94.2%(P < 0.05),respectively.The intraoperative fluoroscopy time of the new technique group was less than that of the conventional technique group(5.37 seconds vs.8.79 seconds,P < 0.05).However,there was no statistical difference in the operating time and the amount of blood loss during operation(P > 0.05).Pedicle screw placement with the free-hand technique which keeps the screw perpendicular to the supraspinal ligament is an accurate,reliable and safe technique to treat simple fracture in the thoracic or lumbar spine. | Juming Li Hong Zhao Hao Xie Lipeng Yu Jifu Wei Min Zong Feng Chen Ziqiang Zhu Ning Zhang Xiaojian Cao | 2014 | The Journal of Biomedical Research2014,28,1: | 7 |

| 9 | A high-Tc dc-SQUID-based single-channel MCG and its performance显示文摘A single-channel high-Tc dc-SQUID magnetometer and gradiometer have been developed to record the magnetic field component perpendicular to the human chest generated by heart-beat. Magnetocardiogram (MCG) measurements have been carried out inside a magnetically shielded room. By sequentially adjusting a non-magnetic patient table with 5 cm pitch in X and Y directions, the field signals on a rectangle grid 5×5 over the chest area were registered in real time trace point by point with a typical dwell time over 30 cardiocycles each. Utilizing standard electrocardiogram (ECG) recordings as timing reference measured simultaneously with the MCG signals, the MCG data were then averaged and combined to form magnetic field patterns every 10 ms or so. Both the current dipole, which is parallel to MCG measuring plane and produces the vertical magnetic field, and its depth were determined as a function of time in a standard way. We have compared the MCG of healthy hearts with that of a heart with right bundle | WANG Huiwu DING Hongsheng ZHANG Lihua HUANG Xuguang CHEN Weichang WANG Ziqiang FENG Ji LIU Yiping ZHAO Shiping REN Yufeng YU Hongwei XU Fengzhi WANG Xiaoyin CHEN Genghua YANG Qiansheng | 2002 | Chinese Science Bulletin2002,47,22: | 2 |

| 18 | Real-time programmable metasurface for terahertz multifunctional wave front engineering显示文摘Terahertz(THz)technologies have become a focus of research in recent years due to their prominent role in envisioned future communication and sensing systems.One of the key challenges facing the field is the need for tools to enable agile engineering of THz wave fronts.Here,we describe a reconfigurable metasurface based on GaN technology with an array-of-subarrays architecture.This subwavelength-spaced array,under the control of a 1-bit digital coding sequence,can switch between an enormous range of possible configurations,providing facile access to nearly arbitrary wave front control for signals near 0.34 THz.We demonstrate wide-angle beam scanning with 1°of angular precision over 70 GHz of bandwidth,as well as the generation of multi-beam and diffuse wave fronts,with a switching speed up to 100 MHz.This device,offering the ability to rapidly reconfigure a propagating wave front for beam-forming or diffusively scattered wide-angle coverage of a scene,will open new realms of possibilities in sensing,imaging,and networking. | Feng Lan Luyang Wang Hongxin Zeng Shixiong Liang Tianyang Song Wenxin Liu Pinaki Mazumder Ziqiang Yang Yaxin Zhang Daniel M.Mittleman | 2023 | Light(Science & Applications)2023,12,9: | 1 |

| 20 | Dynamic bifunctional THz metasurface via dual-mode decoupling显示文摘Metasurfaces have powerful light field manipulation capabilities and have been researched and developed extensively in various fields.With an increasing demand for diverse functionalities,terahertz(THz)metasurfaces are also expanding their domain.In particular,integrating different functionalities into a single device is a compelling domain in metasurfaces.In this work,we demonstrate a functionally decoupled THz metasurface that can incorporate any two functions into one metasurface and switch dynamically through external excitation.This proposed metasurface is formed by the combination of split-ring resonators and phase change material vanadium dioxide(VO_(2)).It operates in the single-ring resonant mode and double-ring resonant mode with varying VO_(2)in insulating and metallic states,respectively.More importantly,the phase modulation is independent in two operating modes,and both cover a 360°cross-polarized phase with efficient polarization conversion.This characteristic makes it obtain arbitrary independent phase information on the metasurface with different modes to switch dual functions dynamically.Here,we experimentally demonstrate the functions of a tunable focal length and large-angle focus deflection of a THz off-axis parabolic mirror to verify the dual-function switching characteristics of the functionally decoupled metasurface.The functionally decoupled metasurface developed in this work broadens the way for the research and application of multifunctional modulation devices in the THz band. | XUAN CONG HONGXIN ZENG SHIQI WANG QIWU SHI SHIXIONG LIANG JIANDONG SUN SEN GONG FENG LAN ZIQIANG YANG YAXIN ZHANG | 2022 | Photonics Research2022,10,9: | 1 |
