| 1 | Disaster prevention design criteria for the estuarine cities:New Orleans and Shanghai The lesson from Hurricane Katrina显示文摘The accurate prediction of the typhoon (hurricane) induced extreme sea environments is very important for the coastal structure design in areas influenced by typhoon (hurricane). In 2005 Hurricane Katrina brought a severe catastrophe in New Orleans by combined effects of hurricane induced extreme sea environments and upper flood of the Mississippi River. Like the New Orleans City, Shanghai is located at the estuarine area of the Changjiang River and the combined effect of typhoon induced extreme sea environments, flood peak runoff from the Changjiang River coupled with the spring tide is the dominate factor for disaster prevention design criteria. The Poisson-nested logistic trivariate compound extreme value distribution (PNLTCEVD) is a new type of joint probability model which is proposed by compounding a discrete distribution (typhoon occurring frequency) into a continuous multivariate joint distribution (typhoon induced extreme events). The new model gives more reasonable predicted results for New Orleans and Shanghai disaster prevention design criteria. | LIU Defu SHI Hongda PANG Liang | 2006 | Acta Oceanologica Sinica2006，25，4： | 16 |
| 2 | Infrared transition properties of vanadium dioxide thin films across semiconductor-metal transition显示文摘Vanadium dioxide thin films were fabricated through annealing vanadium oxide thin films deposited by dual ion beam sputtering. X-ray diffraction (XRD), atom force microscopy (AFM), and Fourier transform infrared spectrum (FTIR) were employed to measure the crystalline structure, surface morphology, and infrared optical transmittance. The phase transition properties were characterized by transmittance. The results show that the annealed vanadium oxide thin film is composed of monoclinic VO2, with preferred orientation of (011). The maximum of transmittance change is beyond 65% as the temperature increases from 20 to 80 C. The reversible changes in optical transmittance against temperature were observed. The change rate of transmittance at short wavelength is higher than that at long wavelength at the same temperature across semiconductor-metal phase transition. This phenomenon was discussed using diffraction effect. | LIANG Jiran HU Ming KAN Qiang LIANG Xiuqin WANG Xiaodong LI Guike CHEN Hongda | 2011 | Rare Metals2011，30，3： | 4 |
| 3 | Sex disparity of lung cancer risk in non-smokers:a multicenter population-based prospective study based on China National Lung Cancer Screening Program显示文摘Background: Non-smokers account for a large proportion of lung cancer patients, especially in Asia, but the attention paid to them is limited compared with smokers. In non-smokers, males display a risk for lung cancer incidence distinct from the females-even after excluding the influence of smoking;but the knowledge regarding the factors causing the difference is sparse. Based on a large multicenter prospective cancer screening cohort in China, we aimed to elucidate the interpretable sex differences caused by known factors and provide clues for primary and secondary prevention.Methods: Risk factors including demographic characteristics, lifestyle factors, family history of cancer, and baseline comorbidity were obtained from 796,283 Chinese non-smoking participants by the baseline risk assessment completed in 2013 to 2018. Cox regression analysis was performed to assess the sex difference in the risk of lung cancer, and the hazard ratios (HRs) that were adjusted for different known factors were calculated and compared to determine the proportion of excess risk and to explain the existing risk factors.Results: With a median follow-up of 4.80 years, 3351 subjects who were diagnosed with lung cancer were selected in the analysis. The lung cancer risk of males was significantly higher than that of females;the HRs in all male non-smokers were 1.29 (95% confidence interval [CI]: 1.20-1.38) after adjusting for the age and 1.38 (95% CI: 1.28-1.50) after adjusting for all factors, which suggested that known factors could not explain the sex difference in the risk of lung cancer in non-smokers. Known factors were 7% (|1.29-1.38|/1.29) more harmful in women than in men. For adenocarcinoma, women showed excess risk higher than men, contrary to squamous cell carcinoma;after adjusting for all factors, 47% ([1.30-1.16]/[1.30-1]) and 4% ([7.02-6.75]/[7.02-1])) of the excess risk was explainable in adenocarcinoma and squamous cell carcinoma. The main causes of gender differences in lung cancer risk were lifestyle factors, baseline comorbidity, and family history.Conclusions: Significant gender differences in the risk of lung cancer were discovered in China non-smokers. Existing risk factors did not explain the excess lung cancer risk of all non-smoking men, and the internal causes for the excess risk still need to be explored;most known risk factors were more harmful to non-smoking women;further exploring the causes of the sex difference would help to improve the prevention and screening programs and protect the non-smoking males from lung cancers. | Zheng Wu Fengwei Tan Zhuoyu Yang Fei Wang Wei Cao Chao Qin Xuesi Dong Yadi Zheng Zilin Luo Liang Zhao Yiwen Yu Yongjie Xu Jiansong Ren Jufang Shi Hongda Chen Jiang Li Wei Tang Sipeng Shen Ning Wu Wanqing Chen Ni Li Jie He | 2022 | Chinese Medical Journal2022，，11： | 3 |
| 4 | Three-dimensional electrical resistivity structure beneath the Cuonadong dome in the Northern Himalayas revealed by magnetotelluric data and its implication显示文摘The North Himalayan gneiss domes(NHGD),as one of the extensional structures widely distributed across the southern Tibetan Plateau,are an important window for studying post-collisional diastrophism and magmation as well as polymetallic mineralization.However,the deep mechanism for the formation of NHGD remains controversial.The magnetotelluric(MT)method was adopted to study the deep structure of the Cuonadong dome in the Northern Himalayas.The characteristics of the dome were explored by using the MT sounding curves and phase tensors.Three-dimensional(3D)MT inversion was performed to determine the electrical resistivity structure beneath the Cuonadong dome.The preferred 3D electrical resistivity model shows that an obvious low-resistivity anomaly develops beneath the Cuonadong dome which is overlaid by a high-resistivity body and surrounded by an apparent subcircular zone of low-resistivity anomalies.The integrated conductivity(longitudinal conductance)from depths of 1-20 km indicates that the average longitudinal conductance at the core of the Cuonadong dome is about 10,000 S.The high-conductivity anomaly at the core is found to be analogous to that of lava,mainly resulting from the crustal partial melting,and the estimated melt content is 11.0-17.3%.The high conductance surrounding the dome reaches 20,000 S on average,which is mainly attributed to saline fluids.MT results in this study support that the Cuonadong dome experienced magmatic diapirism.Taken together with previous geological and geochemical studies,we suggest that under the east-west(E-W)extensional tectonic setting in southern Tibet,deep crustal partial melting constantly accumulated beneath the dome,and therefore the magmatic diapirism resulted in the formation of the Cuonadong dome.In addition,the MT results also indicate that the development of the Cuonadong dome provides abundant mineralizing fluids and the space for migration of metallogenic fluids for(rare-metal)polymetallic mineralization. | Shuai XUE Zhanwu LU Wenhui LI Hongda LIANG Guangwen WANG Haiyan WANG Hongqiang LI Xin LI | 2022 | Science China Earth Sciences2022，65，8： | 1 |
| 5 | Experimental Study on the Hydrodynamic Performance of a Heaving Buoy Assembled on a Net Cage Platform显示文摘To take advantage of the abundance of both fishery and wave energy resources in offshore sea areas,a novel floating platform with a heaving buoy-based wave energy converter(WEC)assembled with a set of net cages is presented in this work.The floating WEC system provides a power supply,while the net cages are used for aquaculture.It is designed to have an independent and self-operation breeding function.An experimental study is carried out to investigate the hydrodynamic performance of the device in a wave tank considering the factors of net cages,draft depth,and power take-off,and results show that these variables have significant effects on wave energy capture.Incident waves with short periods cause intense interactions that allow the device to undergo large relative motion.The draft depth could be determined according to wave period rather than wave height.This study also explores the response amplitude operator of the device and determines its resonance scope.The experimental results could provide reliable information for future studies on phase differences and the design of two-body WECs. | SHI Hongda DONG Xiaochen FENG Liang HAN Zhi | 2019 | Journal of Ocean University of China2019，18，5： | 1 |
| 6 | Fluorescence life-time imaging microscopy(FLIM)monitors tumor cell death triggered by photothermal therapy with MoS_(2) nanosheets显示文摘Recently,photothermal therapy(PTT)has been proved to have great potential in tumor therapy.In the last several years,MoS_(2),as one novel member of nanomaterials,has been applied into PTT due to its excellent photothermal conversion efficacy.In this work,we applied fuorescence lifetime imaging microscopy(FLIM)techniques into monitoring the PPT-triggered cell death under MoS_(2) nanosheet treatment.Two types of MoS_(2) nanosheets(single layer nanosheets and few layer nanosheets)were obtained,both of which exhibited presentable photothermal conversion fficacy,leading to high cell death rates of 4T1 cells(mouse breast cancer cells)under PTT.Next,live cell images of 4T1 cells were obtained via directly labeling the mitochondria with Rodamine123,which were then continuously observed with FLIM technique.FLIM data showed that the fuorescence lifetimes of mitochondria targeting dye in cells treated with each type of MoS_(2) nanosheets significantly increased during PTT treatment.By contrast,the fuorescence lifetime of the same dye in control cells(without nanomaterials)remained constant after laser irradiation.These findings suggest that FLIM can be of great value in monitoring cell death process during PTT of cancer cells,which could provide dynamic data of the cellular microenvironment at single cell level in multiple biomedical applications. | Hongda Liang Zheng Peng Xiao Peng Yufeng Yuan Teng Ma Yiwan Song Jun Song Junle Qu | 2019 | Journal of Innovative Optical Health Sciences2019，，5： | 0 |
| 7 | Highly sensitive vector magnetic fiber sensor based on hyperbolic metamaterials显示文摘Hyperbolic metamaterials(HMMs) are novel artificial materials that excite the surface plasmon resonance(SPR) because of their unique hyperbolic dispersion properties. Herein, to the best of our knowledge, we propose the first HMM-based fiber SPR(HMM-SPR) sensor for vector magnetic detection. By selecting the composite materials and structural parameters of the HMM dispersion management, HMM-SPR sensors can achieve a high refractive index sensitivity of 14.43 μm/RIU. Vector magnetic field detection was performed with the HMM-SPR sensor encapsulated with a magnetic fluid. Compared with other ferrofluidbased magnetic field fiber sensors, the proposed sensor shows pronounced advantages in intensity and direction sensitivity of 1.307 nm/Oe and 7.116 nm/°, respectively. The sensor design approach presented in this paper provides an excellent demonstration of HMM-SPR sensors in various applications. | Shiqi Hu Junhao Liang Jiayao Chen Hongda Cheng Qianyu Lin Weicheng Shi Jinming Yuan Gui-Shi Liu Lei Chen Zhe Chen Norhana Arsad Yaofei Chen Yunhan Luo | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，11： | 0 |
