| 1 | The first metagenome of activated sludge from full-scale anaerobic/anoxic/oxic(A2O) nitrogen and phosphorus removal reactor using Illumina sequencing显示文摘The anaerobic/anoxic/oxic(A2O) process is globally one of the widely used biological sewage treatment processes. This is the first report of a metagenomic analysis using Illumina sequencing of full-scale A2O sludge from a municipal sewage treatment plant.With more than 530,000 clean reads from different taxa and metabolic categories, the metagenome results allow us to gain insight into the functioning of the biological community of the A2O sludge. There are 51 phyla and nearly 900 genera identified from the A2O activated sludge ecosystem. Proteobacteria, Bacteroidetes, Nitrospirae and Chloroflexi are predominant phyla in the activated sludge, suggesting that these organisms play key roles in the biodegradation processes in the A2O sewage treatment system.Nitrospira, Thauera, Dechloromonas and Ignavibacterium, which have abilities to metabolize nitrogen and aromatic compounds, are most prevalent genera. The percent of nitrogen and phosphorus metabolism in the A2O sludge is 2.72% and 1.48%, respectively. In the current A2O sludge, the proportion of Candidatus Accumulibacter is 1.37%, which is several times more than that reported in a recent study of A2O sludge. Among the four processes of nitrogen metabolism, denitrification related genes had the highest number of sequences(76.74%), followed by ammonification(15.77%), nitrogen fixation(3.88%) and nitrification(3.61%). In phylum Planctomycetes, four genera(Planctomyces, Pirellula, Gemmata and Singulisphaera) are included in the top 30 abundant genera, suggesting the key role of ANAMMOX in nitrogen metabolism in the A2O sludge. | Mei Tian Fangqing Zhao Xin Shen Kahou Chu Jinfeng Wang Shuai Chen Yan Guo Hanhu Liu | 2015 | Journal of Environmental Sciences2015，27，9： | 20 |
| 2 | Effect of Cynodon dactylon community on the conservation and reinforcement of riparian shallow soil in the Three Gorges Reservoir area显示文摘Introduction:Riparian vegetation plays a crucial role in soil conservation and riverbank reinforcement.The Three Gorges hydrologic project has significantly changed the pattern of water-level fluctuation and riparian environment,which significantly influenced plant community development and its effect on soil conservation and riverbank protection.Cynodon dactylon,a perennial grass with developed root system and creeping stems,has become a dominant riparian species in the Three Gorges area after the completion of the dam.We aimed to characterize how the soil-root system under the C.dactylon community responded to environmental changes and effects of the soil-root system on shallow soil conservation and riverbank reinforcement through field investigation and laboratory test.Methods:We conducted a field survey and experimental research.Quadrates of a natural C.dactylon community were set up on a riverbank along an altitude gradient.Plants were sampled randomly for the measurements of spatial structure and tensile strength of roots.Soil erosion resistance,soil scour resistance,and shear strength of sampled soil-root systems and control soil were tested in the laboratory.Results:Roots of the C.dactylon community significantly increased soil erosion resistance,soil scour resistance,and shear strength,enhancing the stability of shallow soil and riverbank.Due to water-level fluctuation,C.dactylon at lower altitudes was subjected to less time exposed to air.As a result,the soil-root systems at lower altitudes were characterized by reduced biomass with reduced capacity for soil reinforcement as measured through erosion resistance,soil scour resistance,and shear strength.The correlation analysis indicated that root biomass had a significant positive linear correlation with the enhancement of erosion resistance and scour resistance,and shear strength,respectively.Conclusions:Roots of the C.dactylon community effectively enhanced the stability of riparian shallow soil and riverbank.The fluctuation in water level caused the difference of root growth as the exposed time of plants decreases with the decrease of altitude.The difference of root structure resulted in the variation of the soil-root system in soil conservation and reinforcement. | Fangqing Chen Jinxia Zhang Miao Zhang Jianzhu Wang | 2015 | Ecological Processes2015，4，1： | 10 |

| 6 | Angle estimation for bistatic MIMO radar with unknown mutual coupling based on three-way compressive sensing显示文摘The problem of angle estimation for bistatic multipleinput multiple-output radar in the present of unknown mutual coupling(MC) is investigated, and a three-way compressive sensing(TWCS) estimation algorithm is developed. To exploit the inherent multi-dimensional structure of received data, a trilinear tensor model is firstly formulated. Then the de-coupling operation is followed. Thereafter, the high-order singular value decomposition is applied to compress the high dimensional tensor to a much smaller one. The estimation of the compressed direction matrices are linked to the compressed trilinear model, and finally two overcomplete dictionaries are constructed for angle estimation. Also,Cramer-Rao bounds for angle and MC estimation are derived. The proposed TWCS algorithm is effective from the perspective of estimation accuracy as well as the computational complexity, and it can achieve automatically paired angle estimation. Simulation results show that the proposed method has much better estimation accuracy than the existing algorithms in the low signal-to-noise ratio scenario, and its estimation performance is very close to the parallel factor analysis(PARAFAC) algorithm at the high SNR regions. | Xinhai Wang Gong Zhang Fangqing Wen De Ben Wenbo Liu | 2017 | Journal of Systems Engineering and Electronics2017，28，2： | 4 |
| 7 | Effects of exotic species Larix kaempferi on diversity and activity of soil microorganisms in Dalaoling National Forest Park显示文摘Introduction:Soil microbial community plays a crucial role in the ecological processes of soil ecosystem.Forest species introduction often changes profoundly soil ecological processes in the forest.Larix kaempferi(Lam.)was introduced to China from Japan as a timber tree species in the 1960s.The activity and functional diversity of soil microorganisms in the L.kaempferi forest in Dalaoling National Forest Park in Hubei Province,China,was studied to evaluate the effects of this exotic species on the local soil ecosystems.Methods:Quadrates were set up randomly in the L.kaempferi forests cultivated in 1990 and 1996 and the surrounding Pinus armandii forest cultivated in 1990.Soil samples were collected using a soil corer at five locations along the diagonals in each quadrat.The activity and functional diversity of soil microorganisms were tested using the BIOLOG technique in laboratory.Results:The diversity,activity,and carbon utilization pattern of soil microorganism community and soil physicochemical properties were all impacted by the introduced species.The average well color development(AWCD)and Shannon’s richness index(H)of the soil microorganism community in the L.kaempferi forest decreased with the increase in forest age and were significantly lower than those in the surrounding native P.armandii forest.The carbon source utilization pattern of soil microorganism community in a 23-year-old L.kaempferi forest differed significantly from a 17-year-old L.kaempferi forest and the P.armandii forest.The introduced species also resulted in the changes of soil physicochemical properties.The organic material content,total nitrogen,available nitrogen,and total phosphorus in the soil of L.kaempferi forest were significantly lower than those in the soil of P.armandii forest.Conclusions:Introduction and long-time cultivation of L.kaempferi significantly altered the soil microbial functional diversity and activity and the soil physicochemical properties.The alteration increased with the increase of forest age. | Fangqing Chen Nina Song Guohua Chen Jianzhu Wang | 2015 | Ecological Processes2015，4，1： | 4 |

| 9 | Microbiota-gut-brain axis in autism spectrum disorder显示文摘Extensive studies, largely during the past decade, identify the dynamic and bidirectional interaction between the bacteria resident in the intestines and their host brain along the 'microbiota-gut-brain axis'. This interaction modulates the development and function of the central nervous system and is implicated in neurological disorders. As a neurodevelopmental disorder, autism spectrum disorder (ASD) is considered a historically defect in the brain. With accumulating evidence showing how the microorganisms modulate neural activities, more and more research is focusing on the role of the gut microbiota in mitigating ASD symptoms and the underlying mechanisms. In this review, we describe the intricate and crucial pathways via which the gut microbiota communicates with the brain, the microbiota-gut-brain axis, and summarize the specific pathways that mediate the crosstalk of the gut microbiota to the brain in ASD. | You Yu Fangqing Zhao | 2021 | Journal of Genetics and Genomics2021，48，9： | 4 |

| 11 | Estimation of multipath parameters in wireless communications using multi-way compressive sensing显示文摘This paper addresses the problem of joint angle and delay estimation(JADE) in a multipath communication scenario. A low-complexity multi-way compressive sensing(MCS) estimation algorithm is proposed. The received data are firstly stacked up to a trilinear tensor model. To reduce the computational complexity,three random compression matrices are individually used to reduce each tensor to a much smaller one. JADE then is linked to a low-dimensional trilinear model. Our algorithm has an estimation performance very close to that of the parallel factor analysis(PARAFAC) algorithm and automatic pairing of the two parameter sets. Compared with other methods, such as multiple signal classification(MUSIC), the estimation of signal parameters via rotational invariance techniques(ESPRIT), the MCS algorithm requires neither eigenvalue decomposition of the received signal covariance matrix nor spectral peak searching. It also does not require the channel fading information, which means the proposed algorithm is blind and robust, therefore it has a higher working efficiency.Simulation results indicate the proposed algorithm have a bright future in wireless communications. | Fangqing Wen Gong Zhang De Ben | 2015 | Journal of Systems Science & Complexity2015，28，5： | 3 |

| 13 | Gene analysis of an antiviral protein SP-2 from Chinese wild silkworm, Bombyx mandarina Moore and its bioactivity assay显示文摘The cDNA encoding an antiviral protein SP-2 against BmNPV was cloned from the midgut of Chinese wild silkworm, Bombyx mandarina Moore (GenBank access AY945210) based on the available informa- tion of the domesticated silkworm. Its cDNA was 855 bp encoding 284 amino acids with predicted mo- lecular weight of 29.6 kDa. Its full length in genomics was 1376 bp, including 5 exons and 4 introns. The expression analysis indicated that it was only expressed in midgut, and its expression level was higher during feeding stage of larval instars while very lower during the moltism and mature stages. The de- duced amino acid sequence of this protein showed eight-amino-acid variation compared with the counterpart of domesticated silkworm. Its antiviral activity was assayed through in vitro test. The re- sults indicated that it showed strong bioactivity against BmNPV, and its activity was 1.6 fold higher that the counterpart of domesticated silkworm. | YAO HuiPeng, HE FangQing, GUO AiQin, CAO CuiPing, LU XingMeng & WU XiaoFeng College of Animal Science, Zhejiang University, Hangzhou 310029, China | 2008 | Science China(Life Sciences)2008，51，10： | 2 |
| 14 | Variation of the Vaginal Microbiome During and After Pregnancy in Chinese Women显示文摘A comprehensive profiling of the vaginal microbial communities and their variability enables an accurate description of the microbiome in women.However,there is a lack of studies available on Chinese women.In the present study,the composition of the vaginal microbiota during pregnancy and the 6-week postpartum period of 454 Chinese women was characterized by sequencing the V3-V4 region of the 16S ribosomal RNA(rRNA)gene.The vaginal microbiome showed variations during pregnancy and the postpartum period based on the abortion history,hypertensive disorders,delivery mode,and maternal age.Co-variation of 22 bacterial taxa,including the Lactobacillus genus and two of its species,may account for the common characteristics of the vaginal microbiome under scenarios of different medical histories and pregnancy outcomes.In contrast,discriminant bacterial species were significantly different between women who had preterm birth(PTB)with and without premature rupture of membranes(PROM),and the community state type(CST)IV-A without any predominant Lactobacillus species in the microbiota was more prevalent during pregnancy in the PROM-PTB cases,suggesting that specific bacterial species could be considered to distinguish between different types of PTB.By providing data on Chinese women,this study will enrich the knowledge of the human microbiome and contribute to a better understanding of the association between the vaginal microbiome and reproductive health. | Xiaoai Zhang Qingzhi Zhai Jinfeng Wang Xiuling Ma Bo Xing Hang Fan Zhiying Gao Fangqing Zhao Wei Liu | 2022 | Genomics, Proteomics & Bioinformatics2022，20，2： | 2 |
| 15 | High-order extended coprime array design for direction of arrival estimation显示文摘Nonuniform linear arrays,such as coprime array and nested array,have received great attentions because of the increased degrees of freedom(DOFs)and weakened mutual coupling.In this paper,inspired by the existing coprime array,we propose a high-order extended coprime array(HoECA)for improved direction of arrival(DOA)estimation.We first derive the closed-form expressions for the range of consecutive lags.Then,by changing the inter-element spacing of a uniform linear array(ULA),three cases are proposed and discussed.It is indicated that the HoECA can obtain the largest number of consecutive lags when the spacing takes the maximum value.Finally,by comparing it with the other sparse arrays,the optimized HoECA enjoys a larger number of consecutive lags with mitigating mutual coupling.Simulation results are shown to evaluate the superiority of HoECA over the others in terms of DOF,mutual coupling leakage and estimation accuracy. | SHI Junpeng WEN Fangqing LIU Yongxiang LIU Tianpeng LIU Zhen | 2021 | Journal of Systems Engineering and Electronics2021，32，4： | 2 |

H^+ transport activity was indicated as the stable value of fluorescence quenching per mg membrane proteins. The H^+ transport activities dependent on ATP of the mutant and wild type were 1099 and 558 respectively and their activities dependent on PPi were 358 and 228 separately. | Fangqing Guo Zhangcheng Tang | 1999 | Chinese Science Bulletin1999，44，13： | 2 |
| 17 | A Delay-Aware Congestion Control Protocol for Wireless Sensor Networks显示文摘In wireless sensor networks,congestion leads to buffer overflowing,and increases delay.The traditional solutions use rate adjustment to mitigate congestion,thus increasing the delay.A Delay-aware congestion control protocol(DACC)was presented to mitigate congestion and decrease delay.In order to improve the accuracy of the existing congestion detection model which is based on the buffer occupancy of a single node,DACC presents a new model considering both the real-time buffer occupancy and the average transmission time of packets.DACC uses the untapped bits in the IEEE 802.11 Distributed coordination function(DCF)frames header to carry congestion information.During the congestion alleviation period,DACC presents a channel occupancy mechanism which is based on the real-time buffer occupancy for the purpose of decreasing delay and preventing packet loss.Simulation results indicate that in terms of delay,packet delivery ratio,collision and buffer load,DACC has comparative advantages than those of 802.11 DCF,Priority-based congestion control protocol(PCCP)and Decoupling congestion control and fairness(DCCF). | PEI Tingrui LEI Fangqing LI Zhetao ZHU Gengming PENG Xin Youngjune CHOI Hiroo SEKIYA | 2017 | Chinese Journal of Electronics2017，26，3： | 2 |
