1Control of Bird Feeding Behavior by Tannin1 through Modulating the Biosynthesis of Polyphenols and Fatty Acid-Derived Volatiles in Sorghum显示文摘Bird predation during seed maturation causes great loss to agricultural production.In this study,through GWAS analysis of a large-scale sorghum germplasm diversity panel,we identified that Tannin1,which encodes a WD40 protein functioning in the WD40/MYB/bHLH complex,controls bird feeding behavior in sorghum.Metabolic profiling analysis showed that a group of sorghum accessions preferred by birds contain mutated tan1-a/b alleles and accumulate significantly lower levels of anthocyanins and condensed tannin compounds.In contrast,a variety of aromatic and fatty acid-derived volatiles accumulate at significantly higher levels in these bird-preference accessions.We subsequently conducted both sparrow feeding and sparrow volatile attractant assays,which confirmed,respectively,the antifeedant and attractant functions of these differentially accumulated metabolites.In addition,the connection between the biosynthesis pathway of anthocyanin and proanthocyanidin and the pathway of fatty acid–derived volatile biosynthesis was demonstrated by discovering that Tannin1 complex modulates fatty acid biosynthesis by regulating the expression of SbGL2 in sorghum,thus affecting the accumulation of fatty acid-derived volatiles.Taken together,our study identified Tannin1 as the gene underlying the major locus controlling bird feeding behavior in sorghum,illustrating an example of the identification of an ecologically impactful molecular mechanism from field observation and providing significant insights into the chemistry of bird–plant ecological interactions.Peng Xie Jiayang Shi Sanyuan Tang Chengxuan Chen Aimal Khan Fengxia Zhang Ying Xiong Chao Li Wei He Guodong Wang Fumin Lei Yaorong Wu Qi Xie 2019Molecular Plant2019,12,10:8
2Long-distance ranging with high precision using a soliton microcomb显示文摘Laser-based light detection and ranging(lidar)plays a significant role in both scientific and industrial areas.However,it is difficult for existing lidars to achieve high speed,high precision,and long distance simultaneously.Here,we demonstrate a high-performance lidar based on a chip-scaled soliton microcomb(SMC)that can realize all three specialties simultaneously.Aided by the excellent properties of ultrahigh repetition rate and the smooth envelope of the SMC,traditional optical frequency comb(OFC)-based dispersive interferometry is heavily improved and the measuring dead zone induced by the mismatch between the repetition rate of the OFC and resolution of the optical spectrum analyzer is totally eliminated.Combined with an auxiliary dual-frequency phase-modulated laser range finder,the none-dead-zone measurable range ambiguity is extended up to 1500 m.The proposed SMC lidar is experimentally implemented in both indoor and outdoor environment.In the outdoor baseline field,real-time,high-speed(up to 35 k Hz)measurement of a long distance of^1179 m is achieved with a minimum Allan deviation of 5.6μm at an average time of 0.2 ms(27 nm at an average time of 1.8 s after high-pass filtering).The present SMC lidar approaches a compact,fast,high-precision,and none-dead zone long-distance ranging system,aimed at emerging applications of frontier basic scientific research and advances in industrial manufacturing.JINDONG WANG ZHIZHOU LU WEIQIANG WANG FUMIN ZHANG JIAWEI CHEN YANG WANG JIHUI ZHENG SAI T.CHU WEI ZHAO BRENT E.LITTLE XINGHUA QU WENFU ZHANG 2020Photonics Research2020,8,12:8
3Common-anode LED on a Si substrate for beyond 15 Gbit/s underwater visible light communication显示文摘Visible light communication based on light-emitting diodes(LEDs) has become a promising candidate by providing high data rates, low latency, and secure communication for underwater environments. In this paper,a self-designed common-anode GaN-based five-primary-color LED(RGBYC LED) on a Si substrate is proposed and fabricated. The design of a common anode is used to mitigate the saturation effect for a low-frequency component. Additionally, compared with commercially available LEDs that suffer from nonlinearity distortion,applying the designed LED can provide much better and broader linearity according to the measurement results.Therefore, the modulation depth and system performance can be further improved to implement a high-speed underwater visible light communication(UVLC) system. There is no nonlinearity compensation algorithm applied due to the good linearity of the proposed LED;thus, the offline digital signal processing is simplified. We experimentally demonstrate 14.81 Gbit/s 64 quadrature amplitude modulation(QAM)-discrete multitone(DMT)and 15.17 Gbit/s bit-loading-DMT transmissions through a 1.2-m-long underwater channel based on the proposed RGBYC LED with an intrasymbol frequency-domain averaging channel estimation and zero-forcing equalization.As far as we know, this is the highest data rate for an LED-based UVLC system.YINGJUN ZHOU XIN ZHU FANGCHEN HU JIANYANG SHI FUMIN WANG PENG ZOU JUNLIN LIU FENGYI JIANG NAN CHI 2019Photonics Research2019,7,9:7
4Fe–Mn/MCM-41: Preparation,Characterization,and Catalytic Activity for Methyl Orange in the Process of Heterogeneous Fenton Reaction显示文摘Active Fe-and Mn-loaded MCM-41(Fe–Mn/MCM-41),which was synthesized via a hydrothermal reaction followed by impregnation,is used in the heterogeneous Fenton reaction to degrade methyl orange(MO) in aqueous solution. The synthesized samples were characterized by X-ray diffraction,scanning electron microscopy,transmission electron microscopy,N_2 adsorption–desorption isotherm analysis,Fourier transform infrared spectroscopy,and X-ray photoelectron spectroscopy. Compared with Fe/MCM-41 and Mn/MCM-41,Fe–Mn/MCM-41 showed higher activity for MO degradation and mineralization. Effects of various operating parameters,such as pH,Mn content,and H_2O_2 dosage,on the degradation process were subsequently investigated. Results of experiments on the effect of radical scavengers revealed that the degradation of MO could be attributed to oxidation by HO_·. The synergy of Fe and Mn species in the Fenton oxidation process was also explained.Xubin Zhang Jianxin Dong Zhencheng Hao Wangfeng Cai Fumin Wang 2018Transactions of Tianjin University2018,24,4:6
5Ultrasonication-assisted and gram-scale synthesis of Co-LDH nanosheet aggregates for oxygen evolution reaction显示文摘Electrochemical water splitting(EWS)is a highly clean and efficient method for high-purity hydrogen production.Unfortunately,EWS suffers from the sluggish and complex oxygen evolution reaction(OER)kinetics at anode.At present,the efficient,stable,and low-cost non-precious metal based OER electrocatalyst is still a great and long-term challenge for the future industrial application of EWS technology.Herein,we develop a simple and fast approach for gram-scale synthesis of flower-like cobalt-based layered double hydroxides nanosheet aggregates by ultrasonic synthesis,which show outstanding electrocatalytic performance for the oxygen evolution reaction in alkaline media,such as preeminent stability,small overpotential of 300 mV at 10 mA·cm^−2 and small Tafel slope of 110 mV·dec^−1.Tian-Jiao Wang Xiaoyang Liu Ying Li Fumin Li Ziwei Deng Yu Chen 2020Nano Research2020,13,1:5
6Patterns of magpie nest utilization by a nesting raptor community in a secondary forest显示文摘For a total of 9 years,we examined the patterns of a nesting raptor community that utilized European Magpie(Pica pica) nests in the Zuojia Natural Reserve,northeast China.Eight raptor species and two other bird species were recorded nesting in magpie nests.The reuse rate of abandoned magpie nests was 51.6%,and the number of reused nests was positively correlated with their availability.Raptors utilized 83.3% of the reused abandoned magpie nests.Nests followed for more than 1 year were reused by raptors an average of 1.13 times.Inter-specific nest usurpation was common,with 17.3% of new magpie nests being usurped by raptors,and four cases of usurpation occurred among different raptor species.At the community level,8 of 11 raptor species took over magpie nests to breed in the study area,and 91.9% of their nests came from magpie nests.European Magpies represent the core species in the nest web of the local raptor community that utilizes magpie nests.At the forest stand level,closer proximity to forest edges and greater distances from occupied raptor nests were the best predictors of nest reuse.At the nest-site level,arbor density and canopy coverage were the best predictors of nest reuse.Tong Zhou Haitao Wang Yu Liu Fumin Lei Wei Gao 2009Progress in Natural Science:Materials International2009,19,10:5
7Catalytic performances of heteropoly compounds supported on dealuminated ultra-stable Y zeolite for liquid-phase esterification显示文摘A series of catalysts of 12-Phosphotungstic acid (PW) and its cesium salts immobilizedon dealuminated ultra-stable Y zeolite (DUSY) were prepared. Their specific surface area and acidstrength were characterized, and their catalytic activity, selectivity and stability were evaluated in theliquid-phase esterification of acetic acid with n-butanol. It was found that the catalytic activity could beimproved remarkably by introducing PW onto dealuminated USY (from 49.5% to 86.4%). Howeverthis obvious promotion effect of PW could not be observed on USY supported PW catalyst, whichshowed rather low conversion of less than 25.0%. The supported cesium salt of PW on DUSY catalysgave a very high conversion of n-butanol of 94.6% and the 100% selectivity for n-butyl acetate. Thecatalytic stability test revealed that after 5 reaction cycles, the catalytic activity over PW/DUSY drastically dropped to 47.6%, by contrast, the PW cesium salt/DUSY still showed a high conversion o81.6%. The leaching test for catalysts in water showed that the decrease of activity was closely associated with the solubility of the active heteropoly components on supports into the polar solvent, whichindicates that the catalytic deactivation was mainly due to the lose of the heteropoly species in thereaction medium. The high catalytic stability of the supported cesium salts of PW is suggested to bederived from the water-tolerance of cesium salts of PW in the polar reaction system.ZHANG Fumin WANG Jun YUAN Chaoshu REN Xiaoqian 2006Science China Chemistry2006,49,2:4
8Establishment of an Objective Standard for the Definition of Binary Tropical Cyclones in the Western North Pacific显示文摘To develop an objective standard for defining binary tropical cyclones(BTCs)in the western North Pacific(WNP),two best-track datasets,from the China Meteorological Administration and the Joint Typhoon Warning Center,were adopted for statistical analyses on two important characteristics of BTCs-two TCs approaching each other,and counterclockwise spinning.Based on the high consistency between the two datasets,we established an objective standard,which includes a main standard for defining BTCs and a secondary standard for identifying typical/atypical BTCs.The main standard includes two requirements:two coexisting TCs are a pair of BTCs if(i)the separation distance is≤1800 km,and(ii)this separation maintains for at least 12 h.Meanwhile,the secondary standard defines a typical BTC as one for which there is at least one observation when the two TCs approach each other and spin counterclockwise simultaneously.Under the standard,the ratio of typical BTCs increases as the BTC duration increases or the minimum distance between the two TCs decreases.Then,using the JTWC dataset,it was found that there are 505 pairs of BTCs during the period 1951−2014,including 328 typical BTCs and 177 atypical BTCs,accounting for 65.0%and 35.0%of the total,respectively.In addition,a study of two extreme phenomena-the maximum approaching speed and the maximum counterclockwise angular velocity in typical BTCs-shows that the configuration of the circulation conditions and the distribution of the BTCs favor the formation of these extreme phenomena.Fumin REN Yanjun XIE Biwen YIN Mingyang WANG Guoping LI 2020Advances in Atmospheric Sciences2020,37,11:3
9Incomplete lineage sorting and introgression in the diversification of Chinese spot-billed ducks and mallards显示文摘Incomplete lineage sorting and introgression are 2 major and nonexclusive causes of specieslevel non-monophyly.Distinguishing between these 2 processes is notoriously difficult because they can generate similar genetic signatures.Previous studies have suggested that 2 closely related duck species,the Chinese spot-billed duck Anas zonorhyncha and the mallard A.platyrhynchosvjere polyphyletically intermixed.Here,we utilized a wide geographical sampling,multilocus data and a coalescent-based model to revisit this system.Our study confirms the finding that Chinese spot-billed ducks and Mallards are not monophyletic.There was no apparent interspecific differentiation across loci except those at the mitochondrial DNA(mtDNA)control region and the Z chromosome(CHD1Z).Based on an isolation-with-migration model and the geographical distribution of lineages,we suggest that both introgression and incomplete lineage sorting might contribute to the observed non-monophyly of the 2 closely related duck species.The mtDNA introgression was asymmetric,with high gene flow from Chinese spot-billed ducks to Mallards and negligible gene flow in the opposite direction.Given that the 2 duck species are phenotypically distinctive but weakly genetically differentiated,future work based on genomescale data is necessary to uncover genomic regions that are involved in divergence,and this work may provide further insights into the evolutionary histories of the 2 species and other waterfowls.Wenjuan WANG Yafang WANG Fumin Lei Yang LIU Haitao WANG Jiakuan Chen 2019Current Zoology2019,65,5:2

11Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows显示文摘Known as the‘third polar region’,the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there.Previous studies of birds,animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence.The adaptive processes during the initial phase of highland adaptation remain poorly understood.We studied a human commensal,the Eurasian Tree Sparrow,which has followed human agriculture to the Qinghai-Tibet Plateau.Despite strong phenotypic differentiation at multiple levels,in particular in muscle-related phenotypes,highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years.In a one-month acclimation experiment investigating phenotypic plasticity,we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes.Through population genetic analyses,we identified a signature of polygenic adaptation,whereby shifts in allele frequencies are spread across multiple loci,many of which are associated with muscle-related processes.Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution,shedding light on early stages of adaptive evolution to a novel environment.Yanhua Qu Chunhai Chen Ying Xiong Huishang She Yong E Zhang Yalin Cheng Shane DuBay Dongming Li Per G P Ericson Yan Hao Hongyuan Wang Hongfeng Zhao Gang Song Hailin Zhang Ting Yang Chi Zhang Liping Liang Tianyu Wu Jinyang Zhao Qiang Gao Weiwei Zhai Fumin Lei 2020National Science Review2020,7,1:2
12A Cognitive Memory-Augmented Network for Visual Anomaly Detection显示文摘With the rapid development of automated visual analysis,visual analysis systems have become a popular research topic in the field of computer vision and automated analysis.Visual analysis systems can assist humans to detect anomalous events(e.g.,fighting,walking alone on the grass,etc).In general,the existing methods for visual anomaly detection are usually based on an autoencoder architecture,i.e.,reconstructing the current frame or predicting the future frame.Then,the reconstruction error is adopted as the evaluation metric to identify whether an input is abnormal or not.The flaws of the existing methods are that abnormal samples can also be reconstructed well.In this paper,inspired by the human memory ability,we propose a novel deep neural network(DNN)based model termed cognitive memory-augmented network(CMAN)for the visual anomaly detection problem.The proposed CMAN model assumes that the visual analysis system imitates humans to remember normal samples and then distinguishes abnormal events from the collected videos.Specifically,in the proposed CMAN model,we introduce a memory module that is able to simulate the memory capacity of humans and a density estimation network that can learn the data distribution.The reconstruction errors and the novelty scores are used to distinguish abnormal events from videos.In addition,we develop a two-step scheme to train the proposed model so that the proposed memory module and the density estimation network can cooperate to improve performance.Comprehensive experiments evaluated on various popular benchmarks show the superiority and effectiveness of the proposed CMAN model for visual anomaly detection comparing with the state-of-the-arts methods.The implementation code of our CMAN method can be accessed at http://gffzz188fe103f8f1460asnunuxc0vb5qf669n.ffgz.tsg.suse.edu.cn/CMANcode/CMAN_pytorch.Tian Wang Xing Xu Fumin Shen Yang Yang 2021IEEE/CAA Journal of Automatica Sinica2021,8,7:2
13Study on sulphide capacity of CaO-SiO_2-Al_2O_3-MgO-Fe_tO slags显示文摘The sulphide capacity of CaO-SiO2-Al2O3-MgO-FetO slags was studied at 1773 K using gas-slag equilibrium techniques. Utilizing a Pt crucible, the slag was equilibrated with a mixture of gases, namely, CO, CO2, SO2 and N2 to provide the partial pressure of oxygen and sulphur. It was shown that at fixed FetO and Al2O3 contents and a fixed {(%CaO)+(%MgO)}/(%SiO2) ratio, the sulphide capacity decreases with increasing MgO content. At a constant (%CaO)/(%SiO2) ratio and constant MgO and Al2O3 contents, increas- ing the FetO content of the slags also results in an increase of the sulphide capacity. The rising basicity of (%CaO)/(%SiO2) from 1.0 to 1.4 at fixed MgO, FetO and Al2O3 contents significantly increases the sulphide capacity.Chengli Wang Qing Lu Shuhui Zhang Fumin Li 2006Journal of University of Science and Technology Beijing2006,13,3:2

15CFD simulation study of the effect of baffles on the fluidized bed for hydrogenation of silicon tetrachloride显示文摘In this study,the effect of channel baffles and louver baffles on the flow pattern in the large-scale industrial fluidized beds was studied by computational fluid dynamics(CFD)methods.Then,the effect of flow pattern on the chemical reaction performance was studied for the first time.Simulation results showed that the gas velocity distributed more uniformly,solid particles dispersed more homogeneously and aggregation scarcely occurred in the fluidized bed with louver baffles than that with channel baffles.The residence time distribution indicated that louver baffles remarkably suppressed gas back-mixing in comparison with channel baffles.The reasonable agreements of pressure distribution and reaction results between the simulation in the bed with channel baffles and the data on a large-scale industrial apparatus demonstrated the accuracy of the CFD model.The predicted conversion of SiCl_(4) in the bed with louver baffles(27.44%)was higher than that with channel baffles(22.69%),indicating that louver baffles markedly improved the performance of the fluidized bed.This study could provide useful information for future structural improvements of baffles in large-scale fluidized beds.Ning Liu Xingping Liu Fumin Wang Feng Xin Mingshuai Sun Yi Zhai Xubin Zhang 2022Chinese Journal of Chemical Engineering2022,35,5:2
16Positioning taxonomic research for the future显示文摘Why do taxonomists matter? The work of taxonomists is often understated if not completely misunderstood. Without taxonomists, organisms cannot be accurately identified, neither can these organisms be given universally accepted names, and reliably positioned in the phylogenetic tree of life. Thanks to the work of taxonomists over the last 269 years since Carl Linnaeus established the binomial system, we can now measure the health and wealth of our biodiversity in a refined, science-based inventory prescribed by stringent nomenclatural rules.Deyuan Hong Wenying Zhuang Min Zhu Keping Ma Xiaoquan Wang Dawei Huang Yalin Zhang Guodong Ren Wenjun Bu Wanzhi Cai Dong Ren Ding Yang Aiping Liang Fengyan Bai Runzhi Zhang Fumin Lei Shuqiang Li Hongzhi Kong Lei Cai Yucheng Dai Chaodong Zhu Qisen Yang Jun Chen Zhongli Sha Jianping Jiang Jing Che Donghui Wu Jiatang Li Qiang Wang Xinli Wei Ming Bai Xingyue Liu Xuexin Chen Gexia Qiao 2022Zoological Systematics2022,47,3:2

20ASurvey on Treatment of Hyperlipidemia inPatients with Coronary Artery Disease显示文摘A retrospective analysis was made on the lipid level and management of those patients who experienced coronary angiography for suspected coronary artery disease and those who suffered from acute myocardial infarction admitted to our department from 1994 to 1997. It revealed: ①Incidence of elevated serum lipids (especially total cholesterol) was higher in patients with CHD than those without CHD; ② No significant difference of serum lipids in patients with single or multi vessel disease was seen except higher serum lipids in patients with multi vessel disease; ③Management for elevated lipid in our cases was not active, even neglected in our clinic practice. Attention should be paid on these problems.Yang Zhijian(杨志健)\ Yang Bing(杨 兵) Zhu Tiebing(朱铁兵) Huang Jun(黄 峻) Wang Haiyan(王海燕) Cao Kejiang(曹克将)\ Zhang Fumin(张馥敏) Ma Wenzhu Department of Cardiology, the First Affiliated Hospital of Nanjing Medical University, Nanjing 210029, P.
