1Chromosome-Level Reference Genome and Population Genomic Analysis Provide Insights into the Evolution and Improvement of Domesticated Mulberry (Morns alba)显示文摘Mulberry(Morns spp.)is the sole plant consumed by the domesticated silkworm.However,the genome of domesticated mulberry has not yet been sequenced,and the ploidy level of this species remains unclear.Here,we report a high-quality,chromosome-level domesticated mulberry(Morus alba)genome.Analysis of genomic data and karyotype analyses confirmed that M.alba is a diploid with 28 chromosomes(2/7=2x=28).Population genomic analysis based on resequencing of 134 mulberry accessions classified domesticated mulberry into three geographical groups,namely,Taihu Basin of southeastern China(Hu mulberry),northern and southwestern China,and Japan.Hu mulberry had the lowest nucleotide diversity among these accessions and demonstrated obvious signatures of selection associated with environmental adaptation.Further phylogenetic analysis supports a previous proposal that multiple domesticated mulberry accessions previously classified as different species actually belong to one species.This study expands our understanding of genome evolution of the genus Morus and population structure of domesticated mulberry,which would facilitate mulberry breeding and improvement.Feng Jiao Rongsong Luo Xuelei Dai Hui Liu Gang Yu Shuhua Han Xin Lu Chao Su Qi Chen Qinxia Song Caiting Meng Fanghong Li Hongmei Sun Rui Zhang Tian Hui Yonghua Qian Aichun Zhao Yu Jiang 2020Molecular Plant2020,13,7:10
2Corrosion mechanism of micro-arc oxidation treated biocompatible AZ31 magnesium alloy in simulated body fluid显示文摘The rapid degradation of magnesium(Mg) based alloys has prevented their further use in orthopedic trauma fixation and vascular intervention,and therefore it is essential to investigate the corrosion mechanism for improving the corrosion resistance of these alloys. In this work, the effect of applied voltage on the surface morphology and the corrosion behavior of micro-arc oxidation(MAO) with different voltages were carried out to obtain biocompatible ceramic coatings on AZ31 Mg alloy. The effects of applied voltage on the surface morphology and the corrosion behavior of MAO samples in the simulated body fluid(SBF) were studied systematically. Scanning electron microscope(SEM) and X-ray diffractometer(XRD)were employed to characterize the morphologies and phase compositions of coating before and after corrosion. The results showed that corrosion resistance of the MAO coating obtained at 250 V was better than the others in SBF. The dense layer of MAO coating and the corrosion precipitation were the key factors for corrosion behavior. The corrosion of precipitation Mg(OH)2and the calcium phosphate(Ca–P) minerals on the surface of MAO coatings could enhance their corrosion resistance effectively. In addition, the mechanism of MAO coated Mg alloys was proposed.Ying Li Fang Lu Honglong Li Wenjun Zhu Haobo Pan Guoxin Tan Yonghua Lao Chengyun Ning Guoxin Ni 2014Progress in Natural Science:Materials International2014,24,5:7
3Fuzzy Torque Control of the Bionic Flexible Manipulator Actuated by Pneumatic Muscle Actuators显示文摘A bionic flexible manipulator driven by pneumatic muscle actuator(PMA)can better reflect the flexibility of the mechanism.Current research on PMA mainly focuses on the modeling and control strategy of the pneumatic manipulator system.Compared with traditional electro-hydraulic actuators,the structure of PMA is simple but possesses strong nonlinearity and flexibility,which leads to the difficulty in improving the control accuracy.In this paper,the configuration design of a bionic flexible manipulator is performed by human physiological map,the kinematic model of the mechanism is established,and the dynamics is analyzed by Lagrange method.A fuzzy torque control algorithm is designed based on the computed torque method,where the fuzzy control theory is applied.The hardware experimental system is established.Through the co-simulation contrast test on MATLAB and ADAMS,it is found that the fuzzy torque control algorithm has better tracking performance and higher tracking accuracy than the computed torque method,and is applied to the entity control test.The experimental results show that the fuzzy torque algorithm can better control the trajectory tracking movement of the bionic flexible manipulator.This research proposes a fuzzy torque control algorithm which can compensate the error more effectively,and possesses the preferred trajectory tracking performance.Kai Liu Yining Chen Jiaqi Xu Yang Wu Yonghua Lu Dongbiao Zhao 2019Chinese Journal of Mechanical Engineering2019,32,5:4
4Effect of Shenqi Yangxin decoction on high mobility group box 1and inflammatory signal pathway in a rat model of dilated cardiomyopathy显示文摘OBJECTIVE: To investigate the effects of Shenqi Yangxin decoction(SQYXD) on heart function in a rat model of dilated cardiomyopathy(DCM) and its potential mechanisms.METHODS: Sprague-Dawley rats were randomly divided into normal(10 rats) and DCM(150 rats)groups. DCM was induced by an intraperitoneal injection of adriamycin. Then, DCM baseline group was randomly selected sixteen DCM rats. The remaining DCM rats were randomly divided into DCM control, perindopril, metoprolol, and SQYXD groups. Cardiac function and histological analysis plus biochemical measurement of serum levels of brain natriuretic peptide(BNP), and inflammatory factors were measured. The mRNA and protein expression levels of high-mobility group box 1(HMGB1), Toll-like receptor 4(TLR-4), receptor for advanced glycation end products(RAGE), and nuclear factor-κB(NF-κB) were determined. Myocardial metabolism imaging was performed on the normal, SQYXD and DCM control groups to evaluate the effectiveness of treatments.RESULTS: Rats in the DCM control group exhibited dilated left ventricular diameter, impaired cardiac function, disorganized sarcomere, impaired glucose metabolism, increased heart weight index,and increased levels of BNP, which were improved by treatment with SQYXD. In addition, hearts from rats in the DCM baseline group exhibited significantly higher levels of HMGB1, TLR-4, RAGE, NF-κB,tumor necrosis factor-α, interleukin-1, interleukin-6, interleukin-10, compared with the normal group. Interestingly, the mRNA level of HMGB1 in the DCM baseline group was positively correlated with that of TLR-4, RAGE, NF-κB, BNP, and LVEDD,but negatively correlated with LVEF. SQYXD inhibited the upregulation of HMGB1 expression and its downstream inflammatory factors.CONCLUSION: Shenqi Yangxin decoction effectively reduced the dilated left ventricular diameter and improved heart function in dilated cardiomyopathy. The mechanisms underlying the action on DCM involve regulating the gene and protein expression of HMGB1 and its inflammatory signal pathways in the DCM rat model.Shen Lijuan Lu Shu Zhou Yonghua Xing Qingmin Zhou Chungang Li Lan 2018Journal of Traditional Chinese Medicine2018,38,6:4
5Characteristics of Surface Solar Radiation under Different Air Pollution Conditions over Nanjing, China: Observation and Simulation显示文摘Surface solar radiation (SSR) can affect climate, the hydrological cycle, plant photosynthesis, and solar power. The values of solar radiation at the surface reflect the influence of human activity on radiative climate and environmental effects, so it is a key parameter in the evaluation of climate change and air pollution due to anthropogenic disturbances. This study presents the characteristics of the SSR variation in Nanjing, China, from March 2016 to June 2017, using a combined set of pyranometer and pyrheliometer observations. The SSR seasonal variation and statistical properties are investigated and characterized under different air pollution levels and visibilities. We discuss seasonal variations in visibility, air quality index (AQI), particulate matter (PM10 and PM2.5), and their correlations with SSR. The scattering of solar radiation by particulate matter varies significantly with particle size. Compared with the particulate matter with aerodynamic diameter between 2.5 μm and 10 μm (PM2.5-10), we found that the PM2.5 dominates the variation of scattered radiation due to the differences of single-scattering albedo and phase function. Because of the correlation between PM2.5 and SSR, it is an effective and direct method to estimate PM2.5 by the value of SSR, or vice versa to obtain the SSR by the value of PM2.5. Under clear-sky conditions (clearness index ≥0.5), the visibility is negatively correlated with the diffuse fraction, AQI, PM10, and PM2.5, and their correlation coefficients are ?0.50,?0.60,?0.76, and ?0.92, respectively. The results indicate the linkage between scattered radiation and air quality through the value of visibility.Hao LUO Yong HAN Chunsong LU Jun YANG Yonghua WU 2019Advances in Atmospheric Sciences2019,36,10:4

7Multi-view based neural network for semantic segmentation on 3D scenes显示文摘Dear editor,For semantic segmentation tasks,convolutional neural net work(CNN)based methods have been prevalent for both 2D image semantic segmentation and 3D semantic segmentation.Though traditional methods often use local features to segment a target(For example,in[1]both 2D local features and 3D local features are used to boost recognition ability),CNN based methods[2,3]exhibit much better performance than traditional methods[4].In all the CNN based methods on images,fully convolutional networks(FCNs)[2]are firstly proposed for end-to-end training.Basically,all the following methods are the variants of FCNs.For 3D input,some studies leverage 3D convolution to predict dense 3D semantic voxel maps[5].However,3D convolution has the limitation of low resolution as the GPU memory constraint.Additionally,RGB information is not well considered though it is very important.As semantic segmentation on images has been very good,we can project the semantic segmentation results of images to 3D mesh based on the geometrie relationship.In this study,we mainly exploit the multi-view based neural network for semantic segmentation on 3D scenes.Yonghua LU Mingmin ZHEN Tian FANG 2019Science China(Information Sciences)2019,62,12:3
8A robust three-stage approach to large-scale urban scene recognition显示文摘To obtain the ultimate high-level description of urban scenes, we propose a three-stage approach to recognizing the 3D reconstructed scene with efficient representations. First, we develop a joint semantic labeling method to obtain a semantic labeling of the triangular mesh-based representation by exploiting both image features and geometric features. The labeling is formulated over a conditional random field(CRF) that incorporates local spacial smoothness and multi-view consistency. Then, based on the labeled reconstructed meshes, we refine the man-made object segmentation in the recomposed global orthographic map with a graph partition algorithm, and propagate the coherent segmentation to the entire 3D meshes. Finally, we propose to generate a compact, abstracted geometric representation for each man-made object which is more visually appealing than the original cluttered models. This abstraction algorithm also leverages CRF formation to partition building footprints into minimal sets of structural linear features which are then used to construct profiles for large-scale scenes. The proposed recognition approach is able to robustly handle reconstructions with poor geometry and connectivity, thanks to the higher order CRF formulations which impose the ubiquitous regularity priors in urban scenes. Each stage performs an individual and uncoupling task. The intensive experiments have demonstrated the superior performance of our approach in robustness, accuracy and applicability.Jinglu WANG Yonghua LU Jingbo LIU Long QUAN 2017Science China(Information Sciences)2017,60,10:2

10Phosphorylation of a wheat aquaporin at two sites enhances both plant growth and defense显示文摘Eukaryotic aquaporins share the characteristic of functional multiplicity in transporting distinct substrates and regulating various processes,but the underlying molecular basis for this is largely unknown.Here,we report that the wheat(Triticum aestivum)aquaporin TaPIP2;10 undergoes phosphorylation to promote photosynthesis and productivity and to confer innate immunity against pathogens and a generalist aphid pest.In response to elevated atmospheric CO_(2)concentrations,TaPIP2;10 is phosphorylated at the serine residue S280 and thereafter transports CO_(2)into wheat cells,resulting in enhanced photosynthesis and increased grain yield.In response to apoplastic H_(2)O_(2) induced by pathogen or insect attacks,TaPIP2;10 is phosphorylated at S121 and this phosphorylated form transports H_(2)O_(2) into the cytoplasm,where H_(2)O_(2)intensifies host defenses,restricting further attacks.Wheat resistance and grain yield could be simultaneously increased by TaPIP2;10 overexpression or by expressing a TaPIP2;10 phosphomimic with aspartic acid substitutions at S121 and S280,thereby improving both crop productivity and immunity.Kai Lu Xiaochen Chen Xiaohui Yao Yuyan An Xuan Wang Lina Qin Xiaoxu Li Zuodong Wang Shuo Liu Zhimao Sun Liyuan Zhang Lei Chen Baoyan Li Baoyou Liu Weiyang Wang Xinhua Ding Yonghua Yang Meixiang Zhang Shenshen Zou Hansong Dong 2022Molecular Plant2022,15,11:2
11Identification of Critical Hidden Failure Line Based on State-failure-network显示文摘The hidden failures generally exist in power systems and could give rise to cascading failures.Identification of hidden failures is challenging due to very low occurrence probabilities.This paper proposes a state-failure-network(SF-network)method to overcome the difficulty.The SF-network is formed by searching the failures and states guided by risk estimation indices,in which only the failures and states contributing to the blackout risks are searched and duplicated searches are avoided.Therefore,sufficient hidden failures can be obtained with acceptable computations.Based on the state and failure value calculations in the SF-network,the hidden failure critical component indices can be obtained to quantify the criticalities of the lines.The proposed SF-network method is superior to common sampling based methods in risk estimation accuracy.Besides,the state and failure value calculations in the SF-network used to re-estimate the risks after deployment of measures against hidden failures need shorter time in comparison with other risk re-estimation methods.The IEEE 14-bus and 118-bus systems are used to validate the method.Linzhi Li Lu Liu Hao Wu Yonghua Song Dunwen Song Yi Liu 2022Journal of Modern Power Systems and Clean Energy2022,10,1:2
12An Alternative-Service Recommending Algorithm Based on Semantic Similarity显示文摘With the development of the Internet of Things(Io T), people's lives have become increasingly convenient. It is desirable for smart home(SH) systems to integrate and leverage the enormous information available from IoT. Information can be analyzed to learn user intentions and automatically provide the appropriate services. However, existing service recommendation models typically do not consider the services that are unavailable in a user's living environment. In order to address this problem, we propose a series of semantic models for SH devices. These semantic models can be used to infer user intentions. Based on the models, we proposed a service recommendation probability model and an alternative-service recommending algorithm. The algorithm is devoted to providing appropriate alternative services when the desired service is unavailable. The algorithm has been implemented and achieves accuracy higher than traditional Hidden Markov Model(HMM). The maximum accuracy achieved is 68.3%.Kun Guo Yonghua Li Yueming Lu 2017China Communications2017,14,8:2
