1Impacts of Four Types of ENSO Events on Tropical Cyclones Making Landfall over China's Mainland Based on Three Best-track Datasets显示文摘Impacts of El Nin o Modoki(ENM), La Nin a Modoki(LNM), canonical El Nin o(CEN) and canonical La Nin a(CLN) on tropical cyclones(TCs) that made landfall over China's Mainland during 1951–2011 are analysed using best-track data from China, the USA and Japan. Relative to cold phase years(LNM and CLN), landfalling TCs in warm years(ENM and CEN) have a farther east genesis location, as well as longer track lengths and durations, both in total and before landfall. ENM demonstrates the highest landfall frequency, most northerly mean landfall position, and shortest after-landfall sustainability(track length and duration), which indicate a more frequent and extensive coverage of China's Mainland by TCs, but with shorter after-landfall influence. CEN has low landfall frequency and the most southerly mean landfall location. LNM has the most westerly genesis location, being significantly farther west than the 1951–2011 average and leading to short mean track lengths and durations both in total or before landfall, all of which are significantly shorter than the 1951–2011 average. Variations in the low-level wind anomaly, vertical wind shear, mid-level relative humidity, steering flow, the monsoon trough and the western Pacific subtropical high(WPSH) can to some extent account for the features of frequency, location, track length and duration of landfalling TCs. Since ENSO Modoki is expected to become more frequent in the near future, the results for ENSO Modoki presented in this paper are of particular significance.ZHANG Han GUAN Yuping 2014Advances in Atmospheric Sciences2014,31,1:6
2Investigating different bio-responses of the upper ocean to Typhoon Haitang using Argo and satellite data显示文摘The responses of the upper ocean to Typhoon Haitang in July 2005 are investigated using Argo float and multiplatform satellite data.The results show decreasing sea surface temperature(SST),a deepening of the mixed layer depth(MLD),and enhanced Chlorophyll-a(Chl-a)concentration.Two extreme cool regions are identified.While the magnitude of SST cooling in the two regions is similar,the biological response(Chla enhancement)differs.To facilitate comparisons,the region to the northeast of Taiwan is defined as region A and the region east of Taiwan as region B.Ekman pumping and the intrusion of the Kuroshio play an important role in the enhancement of Chl-a in region A.Cold eddies provide the material source for the formation of the cold center in region B,where mixing is dominant.Because of the relatively high translation speed(5 m/s)in region B,Ekman pumping has little influence on the cooling and Chl-a enhancement processes.Moreover,the MLD is shallower than the nutricline,which means that mixing does not result in a marked increase in nutrients in the euphotic layer(where the nutrient concentration is uniformly depleted).Sea temperatures,in contrast,gradually decrease with depth below the bottom of the mixed layer.In contrast to region A,region B showed no significant enhancement of Chl-a but strong SST cooling.Haixia Shan Yuping Guan Jianping Huang 2014Chinese Science Bulletin2014,59,8:6
3Three-dimensional properties of mesoscale cyclonic warm-core and anticyclonic cold-core eddies in the South China Sea显示文摘In general,a mesoscale cyclonic(anticyclonic)eddy has a colder(warmer)core,and it is considered as a cold(warm)eddy.However,recently research found that there are a number of'abnormal'mesoscale cyclonic(anticyclonic)eddies associated with warm(cold)cores in the South China Sea(SCS).These'abnormal'eddies pose a challenge to previous works on eddy detection,characteristic analysis,eddy-induced heat and salt transports,and even on mesoscale eddy dynamics.Based on a 9-year(2000–2008)numerical modelling data,the cyclonic warm-core eddies(CWEs)and anticyclonic cold-core eddies(ACEs)in the SCS are analyzed.This study found that the highest incidence area of the'abnormal'eddies is the northwest of Luzon Strait.In terms of the eddy snapshot counting method,8620 CWEs and 9879 ACEs are detected,accounting for 14.6%and 15.8%of the total eddy number,respectively.The size of the'abnormal'eddies is usually smaller than that of the'normal'eddies,with the radius only around 50 km.In the generation time aspect,they usually appear within the 0.1–0.3 interval in the normalized eddy lifespan.The survival time of CWEs(ACEs)occupies 16.3%(17.1%)of the total eddy lifespan.Based on two case studies,the intrusion of Kuroshio warm water is considered as a key mechanism for the generation of these'abnormal'eddies near the northeastern SCS.Wenjin Sun Yu Liu Gengxin Chen Wei Tan Xiayan Lin Yuping Guan Changming Dong 2021Acta Oceanologica Sinica2021,40,10:3
4Interbasin exchanges and their roles in global ocean circulation:A study based on 1 400 years' spin up of MOM4p1显示文摘A global prognostic model based on MOM4p1,which is a primitive equation nonBoussinesq numerical model,has been integrated with 1 400 years from the state of rest based on the realistic topography to study the long-term pattern of combined wind-driven and thermodynamically-driven general circulation.The model is driven by monthly climatological mean forces and includes 192×189 horizontal grids and31 pressure-based vertical levels.The main objective is to investigate the mass and heat transports at interbasin passages and their compensations and roles in the global ocean circulation under equilibrium state of long-term spin up.The kinetic energy analysis divides the spin up process into three stages:the quasi-stable state of wind driven current,the growing phase of thermodynamical circulation and the equilibrium state of thermohaline circulation.It is essential to spin up over a thousand years in order to reach the thermohaline equilibrium state from a state of rest.The Arctic Throughflow from the Bering Strait to the Greenland Sea and the Indonesian Throughflow(ITF)are captured and examined with their compensations and existing data.Analysis reveals that the slope structures of sea surface height are the dynamical driving mechanism of the Pacific-Arctic-Atlantic throughflow and ITF.The analysis denotes,in spite of O(1.4×106m3/s)of the southward volume transport in the northern Atlantic,that there is still O(1 PW)of heat transported northward since the northward currents in the upper layer carry much higher temperature water than the southward flowing northern Atlantic deep water(NADW).Meridional volume and heat transports are focused on the contributions to NADW renewals and Atlantic meridional overturning circulation(AMOC).Quantitative descriptions of the interbasin exchanges are explained by meridional compensations and supported by previous observations and numerical modeling results.Analysis indicates that the volume and heat exchanges on the interbasin passages proposed in this article manifest their hub roles in the Great Ocean Conveyor System.ZHU Yaohua WEI Zexun FANG Guohong WANG Yonggang GUAN Yuping 2014Acta Oceanologica Sinica2014,33,1:2
5Application of fluorescence in situ hybridization in the detection of bladder transitional-cell carcinoma: A multi-center clinical study based on Chinese population显示文摘Objective:To evaluate the diagnostic value of fluorescence in situ hybridization(FISH)in bladder cancer.Methods:We enrolled healthy volunteers and patients who were clinically suspected to have bladder cancer and conducted FISH tests and cytology examinations from August 2007 to December 2008.Receiver operating characteristic(ROC)curve analysis was performed and the area under curve(AUC)values were calculated for both the FISH and urine cytology tests.Results:A cohort of 988 healthy volunteers was enrolled to establish a reference range for the normal population.A total of 4807 patients with hematuria were prospectively,randomly enrolled for the simultaneous analysis of urine cytology,FISH testing,and a final diagnosis as determined by the pathologic findings of a biopsy or a surgically-excised specimen.Overall,the sensitivity of FISH in detecting transitional-cell carcinoma was 82.7%,while that of cytology was 33.4%(p<0.001).The sensitivity values of FISH for non-muscle invasive and muscle invasive bladder transitional-cell carcinoma were 81.7%and 89.6%,respectively(p=0.004).The sensitivity values of FISH for low and high grade bladder cancer were 82.6%and 90.1%,respectively(p=0.002).Conclusion:FISH is significantly more sensitive than voided urine cytology for detecting bladder cancer in patients evaluated for gross hematuria at all cancer grades and stages.Higher sensitivity using FISH was obtained in high grade and muscle invasive tumors.Liqun Zhou Kaiwei Yang Xuesong Li Yi Ding Dawei Mu Hanzhong Li Yong Yan Jinyi Li Dongwen Wang Wei Li Yulong Cong Jiangping Gao Kewei Ma Yajun Xiao Sheng Zhang Hongyi Jiang Weilie Hu Qiang Wei Xunbo Jin Zhichen Guan Qingyong Liu Danfeng Xu Xin Gao Yongguang Jiang Weimin Gan Guang Sun Qing Wang Yanhui Liu Jianquan Hou Liping Xie Xishuang Song Fengshuo Jin Jiafu Feng Ming Cai Zhaozhao Liang Jie Zhang Dingwei Ye Lin Qi Lulin Ma Jianzhong Shou Yuping Dai Jianyong Shao Ye Tian Shizhe Hong Tao Xu Chuize Kong Zefeng Kang Yuexin Liu Xun Qu Benkang Shi Shaobin Zheng Yi Lin Shujie Xia Dong Wei Jianbo Wu Weiling Fu Zhiping Wang Jianbo Liang 2019Asian Journal of Urology2019,6,1:2

14In-situ constructing Cu_(1)Bi_(1)bimetallic catalyst to promote the electroreduction of CO_(2)to formate by synergistic electronic and geometric effects显示文摘Electrochemical CO_(2)reduction to formate is a potential approach to achieving global carbon neutrality.Here,Cu1Bi1bimetallic catalyst was prepared by a co-precipitation method.It has a ginger like composite structure(CuO/CuBi_(2)O_(4))and exhibited a high formate faradaic efficiency of 98.07%at–0.98 V and a large current density of–56.12 mA.cm^(-2)at–1.28 V,which is twice as high as Bi2O3catalyst.Especially,high selectivity(FE^(–)_(HCOO)>85%)is maintained over a wide potential window of 500 mV.In-situ Raman measurements and structure characterization revealed that the reduced Cu1Bi1bimetallic catalyst possesses abundant Cu-Bi interfaces and residual Bi-O structures.The abundant Cu-Bi interface structures on the catalyst surface can provide abundant active sites for CO_(2)RR,while the Bi-O structures may stabilize the CO_(2)^(*–)intermediate.The synergistic effect of abundant Cu-Bi interfaces and Bi-O species promotes the efficient synthesis of formate by following the OCHO^(*)pathway.Houan Ren Xiaoyu Wang Xiaomei Zhou Teng Wang Yuping Liu Cai Wang Qingxin Guan Wei Li 2023Journal of Energy Chemistry2023,,4:1
15E2F is required for STAT3-mediated upregulation of cyclin B1 and Cdc2 expressions and contributes to G2–M phase transition显示文摘Activation of transcription factor STAT3 is involved in cell proliferation,differentiation,and cell survival.Constitutive activation of STAT3 pathway has been associated with the oncogenesis of various types of cancers.It has been reported that STAT3 plays a key role in the G1 to S phase cell cycle transition induced by the cytokine receptor subunit gp130,through the upregulation of cyclins D1,D2,D3,A,and Cdc25A and the concomitant downregulation of p21 and p27.However,its role in mediating G2–M phase transition has not been studied.The cyclin B1/Cdc2 complex is widely accepted as the trigger of mitosis in all organisms and is believed to be necessary for progression through S phase and keep active during the G2–M transition and progression.In the present study,we found that activation of STAT3 stimulates cyclin B1 and Cdc2 expressions.Deletion and site-directed mutations on cyclin B1 and Cdc2 promoters indicated that E2F element mediates the upregulation of these two promoters in a STAT3-dependent manner.The findings reported here demonstrated that STAT3 participates in modulating G2–M phase checkpoint by regulating gene expressions of cyclin B1 and Cdc2 via E2F.Jingjie Sun Yuping Du Qiaoling Song Jing Nan Peizhu Guan Jihui Guo Xiao Wang Jinbo Yang Chenyang Zhao 2019Acta Biochimica et Biophysica Sinica2019,51,3:1
16Feature of thermohaline circulation in two-layer conceptual model based on energy constraint显示文摘The assertion that the thermohaline circulation(THC)is driven and sustained by mechanical energy has been increasingly accepted.The simplest conceptual model describing the THC is the Stommel two-box model.Given the vertical stratification in the real ocean,layered models were designed and used.In this research,using a two-layer conceptual model based on energy constraint,we studied basic features of thermal-mode and saline-mode circulations.We focused on the effects of freshwater flux and mixing energy on the intensity and multiple equilibrium states of the THC.The results show that more important than affecting the THC intensity,both the decrease of freshwater flux and increase of mixing energy can lead to an'abrupt transition'in the THC from a stable saline to a stable thermal mode,which further develops the THC energy theory.SHEN Yang GUAN YuPing 2015Science China Earth Sciences2015,58,8:1

20Iterative Phase Noise Suppression for Full-Duplex Communication Systems显示文摘Oscillator phase noise is one of the bottlenecks that limits the self-interference(SI)cancellation capability of full-duplex systems.In this paper,we propose a method for the suppression of common phase error(CPE)and intercarrier interference(ICI)induced by the phase noise in full-duplex orthogonal frequency division multiplexing(OFDM)systems.First,we regard the effect of CPE as a portion of the SI channel and perform estimation,reconstruction and elimination in the time domain.Then,the ICI signal is estimated and suppressed in the frequency domain.Additionally,by analysing the performance of proposed algorithm,we further develop an iterative mechanism to reduce the parameter estimation error and improve SI cancellation capability.Simulation results show that the proposed method has a significant SI cancellation capability improvement over the traditional SI cancellation schemes.Pengxin Guan Yiru Wang Hongkang Yu Yuping Zhao 2023China Communications2023,20,2:0
