| 1 | A quantitative approach to monitoring new sand cay migration in Nansha Islands显示文摘Sand cay is a special kind of islet formed by coral detritus and bioclast, which is common in Nansha Islands of China. Some sand cays play an important role in ocean strategy and economy, but surprisingly we know little about them, especially those recently formed sand cays. In this research, we monitor migration of a new sand cay in Nanxun Jiao(Gaven Reef) using a series of Quick Bird and World View-2 satellite images between June 2006 and August 2013. We conduct a regression between migration distance and wind observational data to examine the migration patterns of the new sand cay. The migration distance is calculated based on the sand cay locations extracted based on Normalized Difference Water Index(NDWI). The wind observational data downloaded from NOAA are reformed into four wind direction vectors. Based on the results of regression, we concluded that the migration of the new sand cay on Nanxun Jiao was significantly associated with the east, west and north wind.East wind was the main influence factor of the migration; its impact strength was almost twice as the west and north wind. The south wind has little effect on the migration of the sand cay, which is partly blocked by the artificial structure in the south. | ZHU Haitian JIANG Xingwei MENG Xuelian FENG Qian CUI Songxue LIANG Chao | 2016 | Acta Oceanologica Sinica2016，35，3： | 9 |
| 2 | The study on an Antarctic sea ice identification algorithm of the HY-2A microwave scatterometer data显示文摘An Antarctic sea ice identification algorithm on the HY-2A scatterometer(HSCAT) employs backscattering coefficient(σ0) and active polarization ratio(APR) for a preliminary sea ice identification.Then standard deviation(STD) filtering and space filtering are carried out.Finally,it is used to identify sea ice.A process uses a σ0,STD threshold and an APR as sea ice indicators.The sea ice identification results are verified using the sea ice distribution data of the ASMR2 released by the National Snow and Ice Data Center as a reference.The results show very good consistence of sea ice development trends,seasonal changes,area distribution,and sea ice edge distribution of the sea ice identification results obtained by this algorithm relative to the ASMR2 sea ice results.The accuracy of a sea ice coverage is 90.8% versus the ASMR2 sea ice results.This indicates that this algorithm is reliable. | ZOU Juhong ZENG Tao GUO Maohua CUI Songxue | 2016 | Acta Oceanologica Sinica2016，35，9： | 4 |
| 3 | Phyto-availability and speciation change of heavy metals in soils amended with lignin as micro-fertilizer显示文摘Lignin is a primary byproduct from the black liquor treatment in paper making industries, its application as micro-fertilizer in agricultural land might provide a promising alternative to sewage discharge. However, application of such a micro-fertilizer might affect the soil properties and result in soil pollution. In this study, the effects of lignin application on phytoavailability and speciation change of heavy metals in soils were investigated. Greenhouse experiments showed that lignin application improved the growth of winter wheat (Triticum aestivum L.) in all three soils investigated. The increase of the biomass for wheat shoot was 59.7%, 39.8% and 12.3% for Beijing soil, Jiangxi soil and Dongbei soil, respectively. In contrast, lignin amendment decreased the concentrations of heavy metals in wheat shoots from 2.2% to 61.0%. Sequential extraction procedure of a three-step BCR was used to investigate the fraction distribution. The extractable fractions were specified as fraction B1: water soluble, exchangeable and carbonate bound or weakly specifically adsorbed; B2: Fe-Mn oxide bound; B3: organic matter and sulfide bound. The results showed that lignin application led to the redistribution of heavy metals in each fraction. Generally, heavy metals decreased in B1 and B2 fractions and increased in B3 fraction. Upon the results short-term application of lignin in agricultural land not only improves the growth of wheat but also reduces the phyto-abailability of heavy metal in wheat. | WANG Songxue, ZHANG Shuzhen, SHAN Xiaoquan & MU Huanzhen Stale Key Laboratory of Environmental Chemistry and Ecotoxicology, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing 100085, China Science Academy of State Administration of Grain, Beijing 100037, China | 2005 | Science China(Life Sciences)2005，48，z1： | 3 |

| 7 | A high wind geophysical model fuction for Quik SCAT wind retrievals and application to Typhoon IOKE显示文摘The geophysical model function(GMF) describes the relationship between a backscattering and a sea surface wind, and enables a wind vector retrieval from backscattering measurements. It is clear that the GMF plays an important role in an ocean wind vector retrieval. The performance of the existing Ku-band model function QSCAT-1 is considered to be effective at low and moderate wind speed ranges. However, in the conditions of higher wind speeds, the existing algorithms diverge alarmingly. owing to the lack of in situ data required for developing the GMF for the high wind conditions, the QSCAT-1 appears to overestimate the s0, which results in underestimating the wind speeds. Several match-up Quik SCAT and special sensor microwave/imager(SSM/I)wind speed measurements of the typhoons occurring in the west Pacific Ocean are analyzed. The results show that the SSM/I wind exhibits better agreement with the 'best track' analysis wind speed than the Quik SCAT wind retrieved using QSCAT-1. On the basis of this evaluation, a correction of the QSCAT-1 model function for wind speed above 16 m/s is proposed, which uses the collocated SSM/I and Quik SCAT measurements as a training set,and a neural network approach as a multiple nonlinear regression technologytechnology.In order to validate the revised GMF for high winds, the modified GMF was applied to the Quik SCAT observations of Hurricane IOKE.The wind estimated by the Quik SCAT for Typhoon IOKE in 2006 was improved with the maximum wind speed reaching 55 m/s. An error analysis was performed using the wind fields from the Holland model as the surface truth. The results show an improved agreement with the Holland model wind when compared with the wind estimated using the QSCAT-1. However, large bias still existed, indicating that the effects of rain must be considered for further improvement. | ZOU Juhong ZENG Tao CUI Songxue | 2015 | Acta Oceanologica Sinica2015，34，7： | 1 |

| 9 | Effect of Particle Shape on Dust Shortwave Direct Radiative Forcing Calculations Based on MODIS Observations for a Case Study显示文摘Assuming spheroidal and spherical particle shapes for mineral dust aerosols,the effect of particle shape on dust aerosol optical depth retrievals,and subsequently on instantaneous shortwave direct radiative forcing(SWDRF) at the top of the atmosphere(TOA),is assessed based on Moderate Resolution Imaging Spectroradiometer(MODIS) data for a case study.Specifically,a simplified aerosol retrieval algorithm based on the principle of the Deep Blue aerosol retrieval method is employed to retrieve dust aerosol optical depths,and the Fu–Liou radiative transfer model is used to derive the instantaneous SWDRF of dust at the TOA for cloud-free conditions.Without considering the effect of particle shape on dust aerosol optical depth retrievals,the effect of particle shape on the scattering properties of dust aerosols(e.g.,extinction efficiency,single scattering albedo and asymmetry factor) is negligible,which can lead to a relative difference of at most 5% for the SWDRF at the TOA.However,the effect of particle shape on the SWDRF cannot be neglected provided that the effect of particle shape on dust aerosol optical depth retrievals is also taken into account for SWDRF calculations.The corresponding results in an instantaneous case study show that the relative differences of the SWDRF at the TOA between spheroids and spheres depend critically on the scattering angles at which dust aerosol optical depths are retrieved,and can be up to 40% for low dust-loading conditions. | FENG Qian CUI Songxue ZHAO Wei | 2015 | Advances in Atmospheric Sciences2015，32，9： | 0 |

| 11 | Guidance and evaluation system for smooth operation of heavy-haul trains显示文摘The operation rules and methods for heavy-haul trains were studied and summarized according to the characteristics of the Daqin Railway,such as a large traffic volume,a high density and high-speed and difficult-to-operate heavy-haul trains.Combined with traction calculation and operation experience,these can be quantificationally decomposed into an evaluation standard for the smooth modularized operation of heavy-haul trains that can be recognized by computers.A train operation guidance system was designed to collect locomotive drivers’operation data,display the actual operation and standard curves in real time and give voice prompts and violation-operation alarms for safety-critical operation.In addition,software for operation analysis and evaluation was developed according to the quantified smooth operation standard.The smooth operation of heavy-haul trains was evaluated and statistically analysed through a comparative analysis of the actual operation records.Moreover,a train impact force detection device capable of monitoring the three-dimensional impact force of heavy-haul trains in real time was developed.Meanwhile,the evaluation standard for smooth operation was verified and optimized by real-time monitoring of the impact force of heavy-haul trains.Finally,on the basis of the above studies,a complete closed-loop management scheme for the smooth operation of heavy-haul trains was constructed,and the objectives of optimizing train operation strategy,standardizing drivers’operations and ensuring the smooth operation of trains were realized through application. | Zhi Zhang Xiang Wei Tao Zhang Songxu Wang | 2020 | Transportation Safety and Environment2020，2，3： | 0 |
| 12 | Naringenin inhibits lipid accumulation by activating the AMPK pathway in vivo and in vitro显示文摘The aim of this study was to explore the lipid-lowering effect of naringenin and the underlying mechanism in high-fat-diet-fed SD rats and 3T3-L1 cells.In this study,SD rats were divided into the normal chow diet group(NCD),high fat diet group(HFD),three treatment groups feeding high-fat diet with naringenin(100,200,400 mg/kg)for 12 weeks.Results indicated that naringenin treatment decreased total cholesterol(TC),triglyceride(TG)and the non-high-density lipoprotein cholesterol(non-HDL-C)levels in serum.Naringenin also alleviated hepatic steatosis and reduced the adipocyte size in the epididymis in high-fat-diet-induced SD rats.In addition,naringenin(25−75μg/mL)decrease TG and TC levels in 3T3 mature adipocytes.The molecular mechanism of naringenin in the treatment of obesity were predicted by using network pharmacology.Real-time PCR analysis results showed that naringenin regulated the expression of lipid metabolism genes.Meanwhile,naringenin increased the AMPK(AMP-activated protein kinase)activity and the expression of AMPK phosphorylated protein in 3T3 mature adipocytes.And the inhibitory effect of naringenin on lipid accumulation in 3T3 adipocytes was abolished by Compound C.Molecular docking results indicated that naringenin could bind to AMPK protein.These results indicated naringenin reduced lipid accumulation through AMPK pathway. | Xiaoyu Cai Songxue Wang Huali Wang Suwen Liu Guishan Liu Huibin Chen Ji Kang Hao Wang | 2023 | Food Science and Human Wellness2023，12，4： | 0 |

| 15 | Millimeter-Wave Bat for Mapping and Quantifying Micromotions in Full Field of View显示文摘Echolocating bats possess remarkable capability of multitarget spatial localization and micromotion sensing in a full field of view(FFOV)even in cluttered environments.Artificial technologies with such capability are highly desirable for various fields.However,current techniques such as visual sensing and laser scanning suffer from numerous fundamental problems.Here,we develop a bioinspired concept of millimeter-wave(mmWave)full-field micromotion sensing,creating a unique mmWave Bat(“mmWBat”),which can map and quantify tiny motions spanning macroscopic toμm length scales of full-field targets simultaneously and accurately.In mmWBat,we show that the micromotions can be measured via the interferometric phase evolution tracking from range-angle joint dimension,integrating with full-field localization and tricky clutter elimination.With our approach,we demonstrate the capacity to solve challenges in three disparate applications:multiperson vital sign monitoring,full-field mechanical vibration measurement,and multiple sound source localization and reconstruction(radiofrequency microphone).Our work could potentially revolutionize full-field micromotion monitoring in a wide spectrum of applications,while may inspiring novel biomimetic wireless sensing systems. | Yuyong Xiong Songxu Li Changzhan Gu Guang Meng Zhike Peng | 2023 | Research2023，，3： | 0 |

| 17 | A network data-based survey and analysis of attention towards breast reconstruction after breast cancer surgery in Chinese and American populations显示文摘Background:Breast reconstruction is an effective technique to rebuild the appearance of the breasts in patients after mastectomy and improves the prognosis.The current study aimed to compare and analyze willingness for breast reconstruction after breast cancer between populations in China and the United States,from the perspective of social concern,using big data analysis.We also aimed to explore factors affecting surgical selection and to identify methods that can improve social cognition and acceptance of breast reconstruction.Methods:Using Baidu and Google,two representative Internet search engines in China and the United States as research tools,and using big data search volume as the benchmark,we compared and analyzed breast reconstruction willingness and attention characteristics between Chinese and American people,based on search heat,geographical distribution,age and sex,keyword distribution,ethnic group,and social development degree.Results:In both the long-term and short-term,Chinese people paid more attention towards searching about breast cancer,but less attention to breast reconstruction after breast cancer surgery.However,in both the short-term and long-term,people from the United States paid more attention towards breast cancer and breast reconstruction with the help of the Internet,showing a synchronous change relationship.There was a large regional difference in the search volume for breast cancer among the Chinese population,while no significant regional differences were noted in the search volume for breast cancer in the United States.However,a large regional difference was observed in the search volume for breast reconstruction between the two countries;people in the coastal and economically developed areas paid more attention to it.Most people who paid attention to breast reconstruction in China were women aged 20–39 years,while the attention among men was low.Search keywords were also limited to breast cancer-related information.However,between Asians and European Americans,Americans paid more attention to breast cancer and were affected by regional development,religious beliefs,and health facilities.Conclusion:Attention towards breast reconstruction after breast cancer was lower in the Chinese population than in the American population,and this difference was closely related to the level of regional development.There is insufficient information on breast reconstruction after breast cancer in recent Internet media.In addition to strengthening communication in clinics,media education is important to improve the cognitive level and social awareness of patients and their families,which is conducive to breast reconstruction. | Songxue Guo Xueqing Hu Zheren Shao Hui Wang Quan Fang Nan Li | 2021 | Chinese Journal Of Plastic and Reconstructive Surgery2021，3，3： | 0 |
