1Coastal seafloor observatory at Xiaoqushan in the East China Sea显示文摘The seafloor observation system is becoming an important infrastructure for marine research because it is transforming oceanic research from temporal investigation to long term observation.The East China Sea coastal seafloor observatory,located between 30°31′44″N,122°15′12″E and 30°31′34″N,122°14′40″E,is constructed near the Xiaoqushan Island outside the Hangzhou Bay on the inner continental shelf of the East China Sea.The observatory is connected by a submarine optical fiber composite power cable that is more than one kilometer long and consists of a special junction box that transmits power and communication signals to different instruments.The special junction box has a variety of waterproof plugs and connects to three different instruments installed in a trawl preventer.The submarine optical fiber composite power cable is landed on the platform by The East China Sea Branch,State Oceanic Administration and the power is continuously supplied by the solar panels and solar battery on the top of the platform.The real time data are directly sent through the cable to the platform and are transmitted by CDMA wireless to the receiver at the State Key Laboratory of Marine Geology of Tongji University.Measurements at the observatory have been taken since April 20,2009 after installation and the results have been interpreted.The characteristics of the near bottom boundary are constrained by a sediment suspension model using portion of the observed data.In particular,discussion is provided on the sea surface height anomaly at Xiaoqushan Island influenced by the tsunami driven by the 2010 Earthquake in Chile.The successful establishment of the coastal seafloor observatory is the first step toward future development of seafloor observation systems in China.It not only accumulates experiences in technology and engineering,but also paves the way for performing important oceanic research using the long term continuous observation platform.XU HuiPing ZHANG YanWei XU ChangWei LI JianRu LIU Ding QIN RuFu LUO ShenQian FAN DaiDu 2011Chinese Science Bulletin2011,56,26:10
2Sedimentation processes and sedimentary characteristics of tidal bores along the north bank of the Qiantang Estuary显示文摘A tidal bore is a unique Earth surface process, characterized by its highly destructive energy, predictable periodicities and magni-tudes, and the production of characteristic sedimentary features. Tidal bores and associated rapid flood flows are highly turbulent flows of the upper-flow regime with a velocity over several meters per second. Reynolds (Re) and Froude (Fr) numbers, respectively, are larger than 104 and 1.0, making them significantly different from regular tidal flows but analogous to turbidity currents. Until now, understanding of tidal-bore depositional processes and products has been limited because of the difficulty and hazards involved with gauging tidal bores directly. The Qiantang bore is known as the largest breaking bore in the world. Field surveys were carried out in May 2010, along the north bank of the Qiantang Estuary to observe the occurrence of peak bores, including regular observations of current, water level and turbidity at the main channel. Several short cores were sampled on the intertidal flats to study the characteristic sedimentary features of tidal bores. Hydrodynamic and sedimentological studies show that the processes of sediment resuspension, transport and deposition are controlled primarily by the tidal bores, and the subsequent abruptly accelerated and decelerated flood flows, which only account for one tenth of each semidiurnal tidal cycle in the estuary. Tidal-bore deposits are generally poorly sorted because of rapid sedimentation after highly mixed suspension by intense turbulence. This behavior is characteristic of the absence of tractive-current depositional components in a C-M diagram. It also goes along with well-developed massive bedding, graded bedding, basal erosion structures, convolute bedding and dewatering structures. Together, these sedimentary features can constitute fingerprinting of turbidites, widely distributed in the deep-water environment. However, a tidal bore is triggered by intensely deformed tidal waves propagating into a shallow-water environment, which returns to regular tidal flows rapidly after the passage of the bore head. The tidal-bore deposits are usually bounded by the intertidal-flat deposits with typical tidal beddings at the top and on both flanks. The difference between tidal-bore deposits (TBD) and tidal sandy/muddy deposits (TSD/TMD) is evident not only in sedimentary structures, but also in the grain-size composition. They can be clearly distinguished in grain-size bivariate plots, typically the plot of mean grain size vs. standard deviation (or sorting). Some trend variations generally exist in mean grain size with TBD>TSD>TMD, sorting with TMD>TBD>TSD (larger value indicating poorer sorting), and both skewness and kurtosis with TSD>TBD>TMD. These findings will undoubtedly shed new light on our understanding of tidal-bore sedimentology, ancient tidal-bore sedimentary facies and environments, and related oil-and-gas field prospecting.FAN DaiDux CAI GuoFu SHANG Shuai WU YiJing ZHANG YanWei GAO Lei 2012Chinese Science Bulletin2012,57,13:8
3Optically stimulated luminescence dosimeter based on CaS:Eu,Sm显示文摘Alkaline earth sulfides (MgS,CaS and BaS) crystal doped with rare-earth ions is an optically stimulated luminescence dosimeter with very high sensitivity,short time constant of the optically stimulated luminescence (OSL) separated perfectly from the stimulation.In this paper,an OSL dosimeter is described.It has linear dose response from 0.01 to 1000 Gy.The equipment,relatively simple and small in size is promising for applications in space exploration and for high dose irradiation and dangerous irradiation conditions.LIU Yanping CHEN Zhaoyang BA Weizhen FAN Yanwei GUO Qi YU Xuefeng CHANG Aiming LU Wu DU Yanzhao 2008Nuclear Science and Techniques2008,19,2:4
4Records of the tsunami induced by the 2010 Chilean earthquake from Xiaoqushan seafloor observatory in the East China Sea显示文摘Sea-level variation can be induced by periodic tides, stochastic wind, air pressure, and swell. Larger sea-level variation has the potential to cause coastal disasters. In this paper, real-time continuous data obtained by the Xiaoqushan seafloor observatory in the East China Sea were analyzed employing frequency power spectral and tidal harmonic methods to extract the major components and periodicities of sea-level change. The sea-level anomaly (sla) was calculated by subtracting the tidal components from the observed sea level data. In the study period, the correlation between sla and the local north-south wind speed was high with a correlation coefficient of 0.65 at the 95% confidence level. The local wind-induced sea-level anomaly (sla wind ) was therefore computed through linear fitting. Although sla wind is one of the main components of sla, the residual sea-level anomaly (sla residual ) obtained by subtracting sla wind from sla is not zero, suggesting that there are other factors besides wind. Detailed analysis of the sea-level data at the time of the 8.8-magnitude Chilean earthquake on February 27, 2010 showed a peak sla residual value of 0.48 m at around 15:00 on February 28, which was highly coincident with the tsunami arrival time forecast by the Pacific Tsunami Warning Center. The peak sla residual event is therefore linked with the tsunami induced by the 2010 Chilean earthquake. This is the first time that a tsunami has been detected using real-time continuous data recorded by a seafloor observatory in the sea off China. Such observations are expected to improve tsunami forecast models and promote the development of a tsunami warning system and a seafloor observatory network in the East China Sea.ZHANG YanWei FAN DaiDu XU HuiPing 2011Chinese Science Bulletin2011,56,27:4
5A CaS:Ce,Sm-based dosimeter for online dosimetry measurement显示文摘A film dosimeter based on optically stimulated luminescence (OSL) material of CaS:Ce,Sm was developed for online irradiation dosimetry measurement.The stimulation is provided by a laser with a wavelength of 980 nm,and the OSL luminescenceis collected by a photodiode.Using 60Co γ-rays,we investigated the dosimetry characteristic of the dosimeter at different dose rates and total doses.The real-time detection results showed that the OSL signals versus total ionizing dose exhibited a good linearity in a dose range of 0.1-185 Gy.SUN Yurun CHEN Zhaoyang FAN Yanwei YAN Shiyou HE Chengfa 2011Nuclear Science and Techniques2011,22,2:3
6Optically stimulated luminescence of Dy^3+-doped NaCaPO4 glass-ceramics显示文摘Dy^3+-doped glass-ceramics containing NaCaPO4 crystals were successfully fabricated by heat treatment at base glass,and the luminescence properties were investigated for potential applications in radiation measurements.The photo luminescence(PL)excitation and emission spectra exhibit transitions related to Dy^3+ions corresponding to the strongest excitation and emission wavelengths at 351 and 575 nm,respectively.The CW-OSL properties as a function of dopant concentration,pre-heating temperature,pre-heating time and signal fading were investigated.The most appropriate Dy^3+ion concentration was found to be 0.25 mol%.The TL glow curves have a broad peak feature peaking at 195±5℃.The fading of the OSL signal would keep stable in five days with the intensity value of about 76.11%.The samples also exhibit good signal reusability and a broad linear dose response range(0.02-1000 Gy).Jie Xu Zhaoyang Chen Minqiang Gai Yanwei Fan Chengfa He 2020Journal of Rare Earths2020,38,9:3
7HBeAg-negative Patients with Chronic Hepatitis B Virus Infection and Normal Alanine Aminotransferase:Wait or Treat?显示文摘Alanine aminotransferase(ALT)is a common clinical indicator of liver inflammation.The current Chinese guidelines for the management of chronic hepatitis B(CHB)recommend antiviral treatment for patients with detectable hepatitis B virus(HBV)DNA and persistent ALT levels(ALTs)exceeding the upper limit of normal.However,it has been recently reported that patients with chronic HBV infection,especially HBeAg-negative patients with persistently normal ALTs,may have liver biopsy findings of significant inflammation and fibrosis.For HBeAg-negative patients with chronic HBV infection and normal ALTs,many controversial questions have been asked.To treat or not?When to initiate the treatment?Which drug is appropriate?In this review,we summarize the available data on the management of HBeAg-negative patients with chronic HBV infection and normal ALTs with the aim of improving the current clinical management.Qiuju Sheng Ning Wang Chong Zhang Yaoxin Fan Yanwei Li Chao Han Ziyi Wang Shuqi Wei Xiaoguang Dou Yang Ding 2022Journal of Clinical and Translational Hepatology2022,10,5:1

11Superconductivity and pseudogap features of an isolated FeAs layer in KCa_(2)Fe_(4)As_(4)F_(2) unraveled by STM/STS显示文摘To reveal the intrinsic properties of the basic superconducting units,i.e.,the single layered FeSe/FeAs in iron-based superconductors or CuO_(2) planes in cuprate superconductors,is a necessary prerequisite for understanding the mechanism of high-Tc superconductivity.Up to now,an isolated FeAs layer has rarely been studied due to the difficulty in materials synthesis.Here,we report a scanning tunneling microscopy/spectroscopy(STM/STS)study on the iron-based superconductor KCa_(2)Fe_(4)As_(4)F_(2).In situ cleavage produced a single FeAs layer covered by a reconstructed K surface,which is isolated from the bulk by the underlying CaF layer and shows multi-band superconductivity with a much lower T_(c) than its bulk counterpart.In the exposed As-terminated regions with coverage of scattered K atoms,a pseudogap was observed,leading to an inhomogeneous superconductivity without long-range phase coherence in real space,which is remarkably similar to the high-T_(c) cuprate superconductors.These results provide a new perspective to understanding the origin of superconductivity in iron-based superconductors.Shuai Shao Fan Zhang Zongyuan Zhang Teng Wang Yanwei Wu Yubing Tu Jie Hou Xingyuan Hou Ning Hao Gang Mu Lei Shan 2023Science China(Physics,Mechanics & Astronomy)2023,66,8:1

14Synthesis and optical properties of novel Gd^(3+)-doped BaZn_(2)(PO_(4))_(2)glass-ceramics for radiation detection applications显示文摘45 P_(2)O_(5)-15 BaO-25 ZnO-15 B2O_(3)glasses doped with different concentrations(0 mol%,0.1 mol%,0.25 mol%,0.5 mol%,and 0.75 mol%)of Gd^(3+)were prepared by a melt-quenching method and treated to fabricate glass-ceramics containing BaZn_(2)(PO_(4))_(2)crystals by controllable crystallization.The structural,optical,and dosimetric properties were investigated.FTIR spectra indicate that the glasses are composed of[PO_(4)],[BO_(3)],and[BO_(4)]basic structural units.The XRD pattern analysis indicates that the samples contain BaZn_(2)(PO_(4))_(2)crystals.In the photoluminesce nce(PL)spectra,two emission bands are observed at 307 and 313 nm due to the^(6)P_(5/2)→^(8)S_(7/2)and^(6)P_(7/2)→^(8)S_(7/2)transitions of Gd^(3+),respectively.The OSL dosimetric properties of glass-ceramics were studied further under beta radiation of90Sr.The optimal Gd^(3+)doping concentration of 0.5 mol%was determined.The fading of the OSL signal shows that the CW-OSL signal of Gd^(3+)-doped BaZn_(2)(PO_(4))_(2)glass-ceramics decays by about 58.95%within120 h,and the intensity remains stable thereafter.The thermoluminescence(TL)curve has three peaks at 164,240,and 344℃.Minimum detectable dose(MDD)of the 0.5 mol%Gd^(3+)-doped BaZn_(2)(PO_(4))_(2)glass-ceramics was calculated as 0.675 mGy.The samples also exhibit good signal reusability and a broad linear dose-response range(0.3-500 Gy).Results show the excellent dosimetric properties of Gd^(3+)-doped BaZn_(2)(PO_(4))_(2)glass-ceramics and their potential application in radiation dosimetry.Wanli Li Zhaoyang Chen Jie Xu Pengjun Zhao Yanwei Fan Chengfa He 2022Journal of Rare Earths2022,40,12:0
15The complete and fully-phased diploid genome of a male Han Chinese显示文摘Since the release of the complete human genome,the priority of human genomic study has now been shifting towards closing gaps in ethnic diversity.Here,we present a fully phased and well-annotated diploid human genome from a Han Chinese male individual(CN1),in which the assemblies of both haploids achieve the telomere-to-telomere(T2T)level.Comparison of this diploid genome with the CHM13 haploid T2T genome revealed significant variations in the centromere.Outside the centromere,we discovered 11,413 structural variations,including numerous novel ones.We also detected thousands of CN1 alleles that have accumulated high substitution rates and a few that have been under positive selection in the East Asian population.Further,we found that CN1 outperforms CHM13 as a reference genome in mapping and variant calling for the East Asian population owing to the distinct structural variants of the two references.Comparison of SNP calling for a large cohort of 8869 Chinese genomes using CN1 and CHM13 as reference respectively showed that the reference bias profoundly impacts rare SNP calling,with nearly 2 million rare SNPs miss-called with different reference genomes.Finally,applying the CN1 as a reference,we discovered 5.80 Mb and 4.21 Mb putative introgression sequences from Neanderthal and Denisovan,respectively,including many East Asian specific ones undetected using CHM13 as the reference.Our analyses reveal the advances of using CN1 as a reference for population genomic studies and paleo-genomic studies.This complete genome will serve as an alternative reference for future genomic studies on the East Asian population.Chentao Yang Yang Zhou Yanni Song Dongya Wu Yan Zeng Lei Nie Panhong Liu Shilong Zhang Guangji Chen Jinjin Xu Hongling Zhou Long Zhou Xiaobo Qian Chenlu Liu Shangjin Tan Chengran Zhou Wei Dai Mengyang Xu Yanwei Qi Xiaobo Wang Lidong Guo Guangyi Fan Aijun Wang Yuan Deng Yong Zhang Jiazheng Jin Yunqiu He Chunxue Guo Guoji Guo Qing Zhou Xun Xu Huanming Yang Jian Wang Shuhua Xu Yafei Mao Xin Jin Jue Ruan Guojie Zhang 2023Cell Research2023,33,10:0

17CACA guidelines for holistic integrative management of glioma显示文摘Glioma of the brain is a kind of tumor originating from neuroglial cells.It is the most common primary intracranial tumor,accounting for~30%of all central nervous system tumors and 80% of malignant brain tumors.Glioma is characterized by high disability and recurrence rates.The disease seriously threatens the life of patients,afects their quality of life,and brings a heavy economic and psychological burden to patients,families,and society.With the progression of molecular genetic testing technology and the completion of various clinical trials,the classifcation scheme for glioma is increasingly well established.Diagnosis and treatment regimens,including traditional and new regimens,are becoming increasingly specialized and standardized.The purpose is to develop a clinical diagnosis and treatment guideline for glioma in the Chinese population suitable for Chinese doctors and the general population based on domestic and international glioma research progress.Thus,domestic practitioners in the feld can obtain current information and provide better service to patients with glioma,promoting the development of domestic clinical medicine and basic research on glioma.Daiming Fan Tao Jiang Wenbin Ma Chuanlu Jiang Yongping You Ying Mao Xiaoguang Qiu Chunsheng Kang Gang Li Qing Mao Xuejun Yang Zhiyong Qin Zhixiong Liu Weimin Wang Xinting Wei Wenbin Li Yunhui Liu Rutong Yu Xinguang Yu Dezhi Kang Yonggao Mou Lei Wang Wei Zhang Zhaoshi Bao Ruichao Chai Baoshi Chen Xing Fan Shengyu Fang Guanzhang Li Lianwang Li Shouwei Li Xing Liu Yanwei Liu Xia Shan Liang Wang Yinyan Wang Yu Wang Zheng Wang Zhiliang Wang Chenxing Wu Wei Yan Pei Yang Gan You Chuanbao Zhang Zhong Zhang Zheng Zhao 2022Holistic Integrative Oncology2022,1,1:0
18Strong Anisotropic Order Parameters at All-Nitride Ferromagnet/Superconductor Interfaces显示文摘Proximity effects between superconductors and ferromagnets(SC/FM)hold paramount importance in comprehending the spin competition transpiring at their interfaces.This competition arises from the interplay between Cooper pairs and ferromagnetic exchange interactions.The proximity effects between transition metal nitrides(TMNs)are scarcely investigated due to the formidable challenges of fabricating high-quality SC/FM interfaces.We fabricated heterostructures comprising SC titanium nitride(TiN)and FM iron nitride(Fe_(3)N)with precise chemical compositions and atomically well-defined interfaces.The magnetoresistance of Fe_(3)N/TiN heterostructures shows a distinct magnetic anisotropy and strongly depends on the external perturbations.Moreover,the superconducting transition temperatureT_(C) and critical field of TiN experience notable suppression when proximity to Fe_(3)N.We observe the intriguing competition of interfacial spin orientations near��T_(C)(∼1.25 K).These findings not only add a new materials system for investigating the interplay between superconductor and ferromagnets,but also potentially provide a building block for future research endeavors and applications in the realms of superconducting spintronic devices.Qiao Jin Meng Yang Guozhu Song Nan Zhao Shengru Chen Haitao Hong Ting Cui Dongke Rong Qianying Wang Yiyan Fan Chen Ge Can Wang Jiachang Bi Yanwei Cao Liusuo Wu Shanmin Wang Kui-Juan Jin Zhi-Gang Cheng Er-Jia Guo 2024Chinese Physics Letters2024,41,2:0
19A robust indium-organic framework with open tubular channels for efficient separation of acetylene显示文摘Considering the tremendous applications and purification requirement of acetylene(C_(2)H_(2)),seeking appropriate adsorbents with high capacity and selectivity is a vital task and remains an enduring challenge.Herein,we designed and synthesized a robust three-dimensional(3D)indium-organic framework([(Me)_(2)NH_(2)][In(L6)_(0.5)(IPA)_(0.5)]·DMA·2H_(2)O(In-L6-IPA,DMA=dimethylammonium,IPA=isopropyl alcohol))featuring two types of one-dimensional(1D)tubular channels.The activated In-L6-IPA displayed high loading for C_(2)H_(2)(104.4 cm^(3)·g^(-1),the second highest value among all reported indium-based metal-organic frameworks(MOFs))and simultaneously selective adsorption for C_(2)H_(2) over CO_(2),C_(2)H_(6),and ethylene(C_(2)H_(4))at 298 K under 100 kPa.Molecular modelling revealed that the porous wall of In-L6-IPA provides more and stronger multiple interactions for C_(2)H_(2) than CO_(2),C_(2)H_(6),and C_(2)H_(4) containing C–H···π,C–H···O,and O···πinteractions.Breakthrough experiments validated the actual separation ability for various ratios of binary C_(2)H_(2)/C_(2)H_(4) and C_(2)H_(2)/CO_(2) mixtures as well as equimolar ternary C_(2)H_(2)/C_(2)H_(4)/CO_(2) and C_(2)H_(2)/C_(2)H_(4)/C_(2)H_(6) mixtures with excellent reusability.Yong-Zhi Li Gang-Ding Wang Fan Xu Qing Yin Danyang Zhao Jiqiu Qi Yanwei Sui Lei Hou Yao-Yu Wang 2024Nano Research2024,17,4:0
