| 1 | Rapid seismic analysis methodology for in-service wind turbine towers显示文摘The wind energy industry has been growing rapidly during the past decades.Along with this growth,engineering problems have gradually emerged in the wind power industry,including those related to the structural reliability of turbine towers.This study proposes a rapid seismic analysis methodology for existing wind turbine tower structures.The method is demonstrated and validated using a case study on a 1.5 MW tubular steel wind turbine tower.Three finite element(FE)models are developed first.Field tests are conducted to obtain the turbine tower's vibrational characteristics.The tests include(1) remotely measuring the tower vibration frequencies using a long range laser Doppler Vibrometer and(2) monitoring the tower structural vibration by mounting accelerometers along the height of the tubular structure.In-situ measurements are used to validate and update the FE models of the wind turbine tower.With the updated FE model that represents the practical structural conditions,seismic analyses are performed to study the structural failure,which is defined by the steel yielding of the tubular tower.This research is anticipated to benefit the management of the increasing number of wind energy converters by providing an understanding of the seismic assessment of existing tubular steel wind turbine towers. | Dai Kaoshan Huang Yichao Gong Changqing Huang Zhenhua Ren Xiaosong | 2015 | Earthquake Engineering and Engineering Vibration2015，14，3： | 20 |
| 2 | Seismic analysis of a LNG storage tank isolated by a multiple friction pendulum system显示文摘The seismic response of an isolated vertical, cylindrical, extra-large liquefi ed natural gas (LNG) tank by a multiple friction pendulum system (MFPS) is analyzed. Most of the extra-large LNG tanks have a fundamental frequency which involves a range of resonance of most earthquake ground motions. It is an effective way to decrease the response of an isolation system used for extra-large LNG storage tanks under a strong earthquake. However, it is diff icult to implement in practice with common isolation bearings due to issues such as low temperature, soft site and other severe environment factors. The extra-large LNG tank isolated by a MFPS is presented in this study to address these problems. A MFPS is appropriate for large displacements induced by earthquakes with long predominant periods. A simplifi ed fi nite element model by Malhotra and Dunkerley is used to determine the usefulness of the isolation system. Data reported and statistically sorted include pile shear, wave height, impulsive acceleration, convective acceleration and outer tank acceleration. The results show that the isolation system has excellent adaptability for different liquid levels and is very effective in controlling the seismic response of extra-large LNG tanks. | Zhang Ruifu Weng Dagen Ren Xiaosong | 2011 | Earthquake Engineering and Engineering Vibration2011，10，2： | 17 |
| 3 | Photonic engineering of superbroadband near-infrared emission in nanoglass composites containing hybrid metal and dielectric nanocrystals显示文摘Photonic media containing hybrid noble metal-dielectric nanocrystals(NCs)represent a wonderland of nanophotonics,with a myriad of uncharted optical functions yet to be explored.Capitalizing on the unique phase separation and spontaneous formation of Au-metal NCs in a gallosilicate glass,we fabricated Ni^2+-doped transparent nanoglass composites(GCs)containing Au-metal/γ-Ga2O3-dielectric NCs.Compared with GCs free of Au-metal NCs,the super broadband near-infrared emission of Ni^2+with a full width at half-maximum over280 nm is enhanced twice in the Au-metal/γ-Ga2O3 dual-phase GCs.A comparison is given as to the spontaneous emission(SPE)properties of Ni^2+in the dual-phase GCs when pumped resonantly and off-resonantly with the localized surface plasmon resonance band of the Au-metal NCs.The important role of the Au-metal NCs in the SPE enhancement is revealed by theoretical simulation based on the finite-element method.Combining the photonic engineering effect of hybrid Au-metal/γ-Ga2O3 NCs and the sensitization effect of Yb^3+on Ni^2+,a record-high enhancement factor of over 10 of the Ni^2+NIR emission is achieved,and optical gain is demonstrated in the GCs at the fiber communication wavelength. | ZHIGANG GAO HAIBO ZHU BOCHAO SUN YINGKE JI XIAOSONG LU HAO TIAN JING REN SHU GUO JIANZHONG ZHANG JUN YANG XIANGENG MENG KATSUHISA TANAKA | 2020 | Photonics Research2020，8，5： | 2 |

| 5 | Systematic evaluation of IgG responses to SARS-CoV-2 spike protein-derived peptides for monitoring COVID-19 patients显示文摘Serological tests play an essential role in monitoring and combating the COVID-19 pandemic.Recombinant spike protein(S protein),especially the S1 protein,is one of the major reagents used for serological tests.However,the high cost of S protein production and possible cross-reactivity with other human coronaviruses pose unavoidable challenges.By taking advantage of a peptide microarray with full spike protein coverage,we analyzed 2,434 sera from 858 COVID-19 patients,63 asymptomatic patients and 610 controls collected from multiple clinical centers.Based on the results,we identified several S protein-derived 12-mer peptides that have high diagnostic performance.In particular,for monitoring the IgG response,one peptide(aa 1148-1159 or S2-78)exhibited a sensitivity(95.5%,95%CI 93.7-96.9%)and specificity(96.7%,95%CI 94.8-98.0%)comparable to those of the S1 protein for the detection of both symptomatic and asymptomatic COVID-19 cases.Furthermore,the diagnostic performance of the S2-78(aa 1148-1159)IgG was successfully validated by ELISA in an independent sample cohort.A panel of four peptides,S1-93(aa 553-564),S1-97(aa 577-588),S1-101(aa 601-612)and S1-105(aa 625-636),that likely will avoid potential cross-reactivity with sera from patients infected by other coronaviruses was constructed.The peptides identified in this study may be applied independently or in combination with the S1 protein for accurate,affordable,and accessible COVID-19 diagnosis. | Yang Li Dan-yun La Qing Lei Zhao-wei Xu Feng Wang Hongyan Hou Lingyun Chen Jiaoxiang Wu Yan Ren Ming-liang Ma Bo Zhang Hong Chen Caizheng Yu Jun-biao Xue Yun-xiao Zheng Xue-ning Wang He-wei Jiang Hai-nan Zhang Huan Qi Shu-juan Guo Yandi Zhang Xiaosong Lin Zongjie Yao Pengfei Pang Dawei Shi Wei Wang Xiao Yang Jie Zhou Huiming Sheng Ziyong Sun Hong Shan Xionglin Fan Sheng-ce Tao | 2021 | Cellular & Molecular Immunology2021，18，3： | 0 |
| 6 | Photonic-reconfigurable entanglement distribution network based on silicon quantum photonics显示文摘The entanglement distribution network connects remote users by sharing entanglement resources,which is essential for realizing quantum internet.We propose a photonic-reconfigurable entanglement distribution network(PR-EDN)based on a silicon quantum photonic chip.The entanglement resources are generated by a quantum light source array based on spontaneous four-wave mixing in silicon waveguides and distributed to different users through time-reversed Hong–Ou–Mandel interference by on-chip Mach–Zehnder interferometers with thermo-optic phase shifters(TOPSs).A chip sample is designed and fabricated,supporting a PR-EDN with3 subnets and 24 users.The network topology of the PR-EDN could be reconfigured in three network states by controlling the quantum interference through the TOPSs,which is demonstrated experimentally.Furthermore,a reconfigurable entanglement-based quantum key distribution network is realized as an application of the PR-EDN.The reconfigurable network topology makes the PR-EDN suitable for future quantum networks requiring complicated network control and management.Moreover,it is also shown that silicon quantum photonic chips have great potential for large-scale PR-EDN,thanks to their capacities for generating and manipulating plenty of entanglement resources. | DONGNING LIU JINGYUAN LIU XIAOSONG REN XUE FENG FANG LIU KAIYU CUI YIDONG HUANG WEI ZHANG | 2023 | Photonics Research2023，11，7： | 0 |
