| 5 | Target maneuver trajectory prediction based on RBF neural network optimized by hybrid algorithm显示文摘Target maneuver trajectory prediction plays an important role in air combat situation awareness and threat assessment.To solve the problem of low prediction accuracy of the traditional prediction method and model,a target maneuver trajectory prediction model based on phase space reconstruction-radial basis function(PSR-RBF)neural network is established by combining the characteristics of trajectory with time continuity.In order to further improve the prediction performance of the model,the rival penalized competitive learning(RPCL)algorithm is introduced to determine the structure of RBF,the Levenberg-Marquardt(LM)and the hybrid algorithm of the improved particle swarm optimization(IPSO)algorithm and the k-means are introduced to optimize the parameter of RBF,and a PSR-RBF neural network is constructed.An independent method of 3D coordinates of the target maneuver trajectory is proposed,and the target manuver trajectory sample data is constructed by using the training data selected in the air combat maneuver instrument(ACMI),and the maneuver trajectory prediction model based on the PSR-RBF neural network is established.In order to verify the precision and real-time performance of the trajectory prediction model,the simulation experiment of target maneuver trajectory is performed.The results show that the prediction performance of the independent method is better,and the accuracy of the PSR-RBF prediction model proposed is better.The prediction confirms the effectiveness and applicability of the proposed method and model. | XI Zhifei XU An KOU Yingxin LI Zhanwu YANG Aiwu | 2021 | Journal of Systems Engineering and Electronics2021，32，2： | 8 |
| 6 | Nest-site selection and breeding ecology of Streaked Wren-Babbler(Napothera brevicaudata)in a tropical limestone forest of southern China显示文摘Background: The breeding information of most birds in Asian tropical areas,especially in limestone forests,is still poorly known.The Streaked Wren-Babbler(Napothera brevicaudata) is an uncommon tropical limestone bird with a small range.We studied its nest-site selection and breeding ecology,in order to understand the adaptations of birds to the conditions of tropical limestone forest in southern China.Methods: We used methods of systematical searching and parent-following to locate the nests of the Streaked Wren-Babbler.We measured characteristics of nest sites and rock cavities.Data loggers and video cameras were used to monitor the breeding behavior.Results: All the observed nests of the Streaked Wren-Babbler were placed in natural shallow cavities or deep holes in large boulders or limestone cliffs.The great majority(96.6%) of Streaked Wren-Babbler nests had three eggs with an average fresh weight of 3.46-± 0.43 g(n = 36,range 2.52-4.20 g).Most(80.4%) females laid their first eggs between March and April(n = 46).The average incubation and nestling period of the Streaked Wren-Babbler was 10.2 range 9-11 days),respectively.Most(87.9%) nests h± 0.4 days(n = 5,range 1011 days) and 10.5 ± 0.8 days(n = 6,ad at least one nestling fledge between 2011 and 2013(n = 33).Conclusions: Our study suggests that several features of the breeding ecology of the Streaked Wren-Babbler,including building nests in rocky cavities,commencing breeding earlier than most species,and reducing foraging times during the incubation period,are well-adapted to the unique habitat of tropical limestone forest. | Aiwu Jiang Demeng Jiang Fang Zhou Eben Goodale | 2017 | Avian Research2017，8，4： | 7 |
| 7 | Chromatin-remodeling factor OsINO80 is involved in regulation of gibberellin biosynthesis and is crucial for rice plant growth and development显示文摘The phytohormone gibberellin(GA) plays essential roles in plant growth and development. Here,we report that OsINO80, a conserved ATP-dependent chromatin-remodeling factor in rice(Oryza sativa), functions in both GA biosynthesis and diverse biological processes. OsINO80-knockdown mutants, derived from either T-DNA insertion or RNA interference, display typical GA-deficient phenotypes, including dwarfism, reduced cell length, late flowering, retarded seed germination and impaired reproductive development. Consistently, transcriptome analyses reveal that OsINO80 knockdown results in downregulation by more than two-fold of over 1,000 genes, including the GA biosynthesis genes CPS_1 and GA_3ox_2, and the dwarf phenotype of OsINO80-knockdown mutants can be rescued by the application of exogenous GA3. Chromatin immunoprecipitation(Ch IP) experiments show that OsINO80 directly binds to the chromatin of CPS1 and GA_3ox_2 loci. Biochemical assays establish that OsINO80 specially interacts with histone variant H_2A.Z and the H_2A.Z enrichments at CPS_1 and GA_3ox_2 are decreased in OsINO80-knockdown mutants. Thus, our study identified a rice chromatin-remodeling factor,OsINO80, and demonstrated that OsINO80 is involved in regulation of the GA biosynthesis pathway and plays critical functions for many aspects of rice plant growth and development. | Chao Li Yuhao Liu Wen-Hui Shen Yu Yu Aiwu Dong | 2018 | Journal of Integrative Plant Biology2018，60，2： | 7 |
| 8 | Transcription factors AS1 and AS2 interact with LHP1 to repress KNOX genes in Arabidopsis显示文摘Polycomb group proteins are important repressors of numerous genes in higher eukaryotes. However, the mechanism by which Polycomb group proteins are recruited to specific genes is poorly understood. In Arabidopsis, LIKE HETEROCHROMATIN PROTEIN 1(LHP1), also known as TERMINAL FLOWER 2, was originally proposed as a subunit of polycomb repressive complex 1(PRC1) that could bind the tri-methylated lysine 27 of histone H3(H3K27me3) established by the PRC2. In this work, we show that LHP1 mainly functions with PRC2 to establish H3K27me3, but not with PRC1 to catalyze monoubiquitination at lysine 119 of histone H2 A. Our results show that complexes of the transcription factors ASYMMETRIC LEAVES 1(AS1) and AS2 could help to establish the H3K27me3 modification at the chromatin regions of Class-I KNOTTED1-like homeobox(KNOX) genes BREVIPEDICELLUS andKNAT2 via direct interactions with LHP1. Additionally, our transcriptome analysis indicated that there are probably more common target genes of AS1 and LHP1 besides Class-I KNOX genes during leaf development in Arabidopsis. | Zhongfei Li Bin Li Jian Liu Zhihao Guo Yuhao Liu Yan Li Wen-Hui Shen Ying Huang Hai Huang Yijing Zhang Aiwu Dong | 2016 | Journal of Integrative Plant Biology2016，58，12： | 6 |
| 9 | Predicted no-effect concentrations for mercury species and ecological risk assessment for mercury pollution in aquatic environment显示文摘Mercury(Hg) exists in different chemical forms presenting varied toxic potentials. It is necessary to explore an ecological risk assessment method for different mercury species in aquatic environment. The predicted no-effect concentrations(PNECs) for Hg(Ⅱ) and methyl mercury(Me Hg) in the aqueous phase, calculated using the species sensitivity distribution method and the assessment factor method, were 0.39 and 6.5 × 10-3μg/L, respectively. The partition theory of Hg between sediment and aqueous phases was considered, along with PNECs for the aqueous phase to conduct an ecological risk assessment for Hg in the sediment phase. Two case studies, one in China and one in the Western Black Sea, were conducted using these PNECs. The toxicity of mercury is heavily dependent on their forms,and their potential ecological risk should be respectively evaluated on the basis of mercury species. | Meng Du Dongbin Wei Zhuowei Tan Aiwu Lin Yuguo Du | 2015 | Journal of Environmental Sciences2015，27，2： | 6 |
| 10 | Rapid iterative incremental model of the intermittent chaos of deep hole developing in coal-gas outburst显示文摘In view of the occurrence of the coal and gas, outburst coal body separates in series of layer form, and tosses in a series of coal shell, and the morphological characteristics of the holes that formed in the coal layers are very similar to some iterative morphological characteristics of the system state under highly nonlinear condition in chaos theory. Two kinds of morphology as well as their starting and end states are comparatively studied in this paper. The research results indicate that the outburst coal and rock system is in a chaotic state of lower nested hierarchy before outburst, and the process that lots of holes form owing to continuous outburst of a series of coal shells in a short time is in a rhythmical fast iterative stage of intermittent chaos state. And the state of the coal-gas system is in a stable equilibrium state after outburst. The behaviors of outburst occurrence, development and termination, based on the universal properties of various nonlinear mappings in describing complex problems, can be described by iterative operation in mathematics which uses the Logistic function f (x,μ)=μx(1-x) and the composite function F(3, x) = f(3)(x, μ) as kernel function. The primary equation of relative hole depth x and outburst parameter l in kernel function are given in this paper. The given results can deepen and enrich the understanding of physical essence of outburst. | Pan Yue Li Aiwu | 2013 | International Journal of Mining Science and Technology2013，23，2： | 5 |
| 11 | An update on histone lysine methylation in plants显示文摘Histone methylation plays crucial roles in epigenetic regulation. The SET domain proteins are now recognized as generally having methyltransferase activity targeted to specific lysine residues of histones. The enzymes and their specific histone lysine methylation have enormous impacts on the regulation of chromatin structure and function. In this review, we discuss recent advances made on histone lysine methylations and their diverse functions in plant growth and development. | Yu Yu Zhongyuan Bu Wen-Hui Shen Aiwu Dong | 2009 | Progress in Natural Science:Materials International2009，19，4： | 5 |
| 12 | The potential risk assessment for different arsenic species in the aquatic environment显示文摘The different toxicity characteristics of arsenic species result in discrepant ecological risk.The predicted no-effect concentrations(PNECs) 43.65, 250.18, and 2.00 × 103μg/L were calculated for As(III), As(V), and dimethylarsinic acid in aqueous phase, respectively. With these PNECs, the ecological risk from arsenic species in Pearl River Delta in China and Kwabrafo stream in Ghana was evaluated. It was found that the risk from As(III) and As(V)in the samples from Pearl River Delta was low, while much high in Kwabrafo stream. This study implies that ecological risk of arsenic should be evaluated basing on its species. | Meng Du Dongbin Wei Zhuowei Tan Aiwu Lin Yuguo Du | 2015 | Journal of Environmental Sciences2015，27，1： | 4 |
| 13 | Effect of Shengmai Yin on the DNA methylation status of nasopharyngeal carcinoma cell and its radioresistant strains显示文摘Shengmai Yin(SMY)is a Chinese herbal decoction that effectively alleviates the side effects of radiotherapy in various cancers and helps achieve radiotherapy’s clinical efficacy.In this study,we explored the interaction mechanism among SMY,DNA methylation,and nasopharyngeal carcinoma(NPC).We identified differences in DNA methylation levels in NPC CNE-2 cells and its radioresistant cells(CNE-2R)using the methylated DNA immunoprecipitation array and found that CNE-2R cells showed genomewide changes in methylation status towards a state of hypomethylation.SMY may restore its original DNA methylation status,and thus,enhance radiosensitivity.Furthermore,we confirmed that the differential gene Tenascin-C(TNC)was overexpressed in CNE-2R cells and that SMY downregulated TNC expression.This downregulation of TNC inhibited NPC cell radiation resistance,migration,and invasion.Furthermore,we found that TNC was hypomethylated in CNE-2R cells and partially restored to a hypermethylated state after SMY intervention.DNA methyltransferases 3 a may be the key protein in DNA methylation of TNC. | Shiya Liu Zhiyuan Wang Daoqi Zhu Jiabin Yang Dandan Lou Ruijiao Gao Zetai Wang Aiwu Li Ying Lv Qin Fan | 2021 | Journal of Pharmaceutical Analysis2021，11，6： | 4 |
| 14 | The influence of ^(18)F-fluorodeoxyglucose positron emission tomography/computed tomography on the N-and M-staging and subsequent clinical management of intrahepatic cholangiocarcinoma显示文摘Background:Intrahepatic cholangiocarcinoma(ICC)is a highly metastatic cancer.^(18)F-fluorodeoxyglucose positron emission tomography/computed tomography(^(18)F-FDG PET/CT)enables sensitive tumor and metastasis detection.Our aim is to evaluate the influence of pre-treatment PET/CT on the N-and M-staging and subsequent clinical management in ICC patients.Methods:Between August 2010 and August 2018,660 consecutive ICC patients,without prior anti-tumor treatments nor other malignancies,were enrolled.The diagnostic performance of PET/CT on the N-and M-staging was compared with conventional imaging,and the preoperative staging accuracy and treatment re-allocation by PET/CT were retrospectively calculated.Survival difference was compared between patients receiving PET/CT or not after propensity score matching.Results:Patients were divided into group A(n=291)and group B(n=369)according to whether PET/CT was performed.Among 291 patients with both PET/CT and conventional imaging for staging in group A,PET/CT showed significantly higher sensitivity(83.0%vs.70.5%,P=0.001),specificity(88.3%vs.74.9%,P<0.001)and accuracy(86.3%vs.73.2%,P<0.001)than conventional imaging in diagnosing regional lymph node metastasis,as well as higher sensitivity(87.8%vs.67.6%,P<0.001)and accuracy(93.5%vs.89.3%,P=0.023)in diagnosing distant metastasis.Overall,PET/CT improved the accuracy of preoperative staging from 60.1%to 71.8%(P<0.001),and modified clinical treatment strategy in 5.8%(17/291)of ICC patients,with unique roles in different tumor-node-metastasis(TNM)stages.High tumor-to-non-tumor ratio(TNR)predicted poor overall survival[hazard ratio(HR)=2.17;95%confidence interval(CI):1.49-3.15;P<0.001].Furthermore,patients performing PET/CT had longer overall survival compared with those without PET/CT(HR=0.74;95%CI:0.58-0.93;P=0.011)after propensity score matching.Conclusions:PET/CT was valuable for diagnosing regional lymph node metastasis and distant metastasis in ICC patients,and facilitated accurate tumor staging and optimal treatment allocation. | Youpei Lin Huanhuan Chong Guohe Song Chenhao Zhang Liangqing Dong Ling Aye Fei Liang Shuaixi Yang Mengsu Zeng Guangyu Ding Shu Zhang Jieyi Shi Aiwu Ke Xiaoying Wang Jian Zhou Jia Fan Qiang Gao | 2022 | Hepatobiliary Surgery and Nutrition2022，11，5： | 3 |
| 15 | A 3D-printed modular magnetic digital microfluidic architecture for on-demand bioanalysis显示文摘Magnetic digital microfluidics(MDM)manipulates fluids in the form of droplets on an open substrate,and incorporates surface energy traps(SETs)to facilitate the droplet manipulation.Conventional MDM devices are fabricated monolithically,which makes it difficult to modify the device configuration without completely overhauling the original design.In this paper,we present a modular MDM architecture that enables rapid on-demand configuration and re-configuration of MDM platforms for customized bioanalyses.Each modular component contains a SET and a Lego-like antistud that fits onto a base board with Lego-like studs.We illustrate the versatility of the modular MDM architecture in biomarker sensing,pathogen identification,antibiotic resistance determination,and biochemical quantification by demonstrating immunoassays,phenotypical assays and enzymatic assays on various modular MDM platforms configured on demand to accomplish the fluidic operations required by assorted bioanalytical assays.The modular MDM architecture promises great potential for point-of-care diagnostics by offering on-demand customization of testing platforms for various categories of diagnostic assays.It also provides a new avenue for microfluidic assay development with its high configurability which would significantly reduce the time and cost of the development cycle. | Pojchanun Kanitthamniyom Aiwu Zhou Shilun Feng Aiqun Liu Shawn Vasoo Yi Zhang | 2020 | Microsystems & Nanoengineering2020，6，1： | 3 |
| 16 | Brood sex ratio in the Yellow-bellied Prinia(Prinia flaviventris)显示文摘Background:The adjustment of sex ratios in birds can occur at the egg and nestling stages. Previous studies showed that the sex ratio was affected by environmental factors and parental condition; it may result in seasonal and ecosystem differences.Methods:In this study, the brood sex ratio of the Yellow-bellied Prinia(Prinia flaviventris) in the Nonggang area, Guangxi, southwestern China, was investigated during the breeding season from May to June in 2013 using PCR amplification from whole-genome DNA extracted from blood samples. A total of 31 nests of Yellow-bellied Prinia, including 132 brood fledglings and 31 pairs, were sampled.Results:The results showed that the brood sex ratio of the Yellow-bellied Prinia was 1:1, and sex ratios of different nests were evenly distributed within the study area. No significant relationship was found between parental quality and nest characteristics with the brood sex ratio.Conclusions:The present study indicated that no brood sex ratio bias in the Yellow-bellied Prinia highlighted the complexity of sex ratio adjustment in birds. In spite of our negative results, the lack of an association between brood sex ratio and parental quality and environmental factors in the Yellow-bellied Prinia provides valuable information on the adjustment of sex ratios in birds. | Zhifeng Ding Fang Ji Qiuli Huang Longwu Wang Aiwu Jiang Chunlan Zhang Yongjun Feng Yuan Tian Huijian Hu Wei Liang | 2017 | Avian Research2017，8，2： | 2 |
| 17 | 3D dahlia-like NiAl-LDH/CdS heterosystem coordinating with 2D/2D interface for efficient and selective conversion of CO_(2)显示文摘Developing photocatalyst with high activity,superior stability and prominent selectivity for CO_(2)conversion is of great importance for the target of carbon neutralization.Herein,3 D dahlia-like NiAl-LDH/CdS heterosystem is developed through in-situ decoration of exfoliated CdS nanosheets on the scaffold of NiAl-LDH and the on-spot self-assembly.The formation of a hierarchical architecture collaborating with well-defined 2 D/2 D interfacial interaction is constructed by optimizing the ratio of CdS integrated in the formation of the heterojunction.The light-harvesting capacity of NiAl-LDH/CdS is improved by this unique scaffold,and the charge transfer between NiAl-LDH and CdS is effectively facilitated by virtue of the unique 2 D/2 D interface.As a result,the 3 D hierarchical NiAl-LDH/CdS heterosystem presents 12.45μmol g^(-1)h^(-1)of CO production(3.3 and 1.6 folds of pristine NiAl-LDH and CdS) with 96% selectivity and superior stability.This 3 D hierarchical design collaborating with 2 D/2 D interfacial interaction provides a new avenue to develop ideal catalysts for artificial photosynthesis. | Xiaoyue Zhang Yong Yang Lijun Xiong Tianyu Wang Zheng Tang Panjie Li Nan Yin Aiwu Sun Jinyou Shen | 2022 | Chinese Chemical Letters2022，33，4： | 2 |

| 19 | Investigation of the oil-seawater mixed flow under an electromagnetic field显示文摘The electromagnetic separation method is a new approach to treat ship-based marine oily wastewater,in which oil droplets are dispersed in seawater(oil-seawater mixed flow).In order to clarify the separation process and determine the separation characteristics,the flow field and volume fraction of the oil droplets of the oil-seawater mixed flow under an applied electromagnetic field with different operating conditions were investigated by 2D numerical simulations with the Eulerian model.The results show that:(1)the downward Lorentz force causes seawater to flow downwards and the oil droplets to move upwards due to the electromagnetic separation force in the effective section of the separation channel;(2)the volume fraction of the oil droplets at the top of the outlet section increases with the current density,magnetic field,and the diameter of the oil droplet and decreases with the inlet velocity of the oily seawater.The results provide useful guidance for the design of electromagnetic separation devices of the oil-seawater mixed flow. | Aiwu Peng Lingzhi Zhao Xiaoqiang Chen Qingfan Zhang Ciwen Sha Jianping Zhao Ran Li Zhaolian Wang | 2019 | Acta Oceanologica Sinica2019，38，7： | 2 |
