| 1 | Bioaccumulation, subcellular distribution and chemical forms of yttrium in rice seedling显示文摘Yttrium(Y) accumulation in soil is a serious environment problem in China. To understand the mechanisms involved in Y tolerance and detoxification in rice seedling, the bioaccumulation, subcellular distribution, and chemical forms of Y was investigated in the present study. The results show that the content of Y both in roots and shoots increases with the increasing concentration of Y, and a large amount of Y is stored in roots. Subcellular distribution of Y in rice indicates that the majority of Y is bound to cell wall. Meanwhile, various chemical forms of Y is absorbed by rice. The greatest amount of Y is extracted by 2% hydrate acetic acid(HAc) and 0.6 mol/L HCl(particularly 2% HAc), which indicates that most of Y is combined with un-dissolved phosphate and oxalate(particularly phosphate). Cluster analysis, based on Y abundance levels, reveals the relationship between Y distribution patterns and chemical forms. Our results imply that Y forming of precipitates with phosphate(and/or oxalate) and depositing in the cell wall may be a key strategy for Y detoxicity and tolerance in rice. | Shengnan Zheng Caiyun Zhang Kailun Shi Jinxiao Wang Guanjun Sun Qiaochu Hu Fengyun Zhao Xue Wang | 2018 | Journal of Rare Earths2018，36，3： | 4 |
| 2 | Genetic architecture and key genes controlling the diversity of oil composition in rice grains显示文摘Rice grain oil is a valuable nutrient source.However,the genetic basis of oil biosynthesis in rice grains remains unclear.In this study,we performed a genome-wide association study on oil composition and oil concentration in a diverse panel of 533 cultivated rice accessions.High variation for 11 oil-related traits was observed,and the oil composition of rice grains showed differentiation among the subpopulations.We identified 46 loci that are significantly associated with grain oil concentration or composition,16 of which were detected in three recombinant inbred line populations.Twenty-six candidate genes encoding enzymes involved in oil metabolism were identified from these 46 loci,four of which(PAL6,LIN6,MYR2,and ARA6)were found to contribute to natural variation in oil composition and to show differentiation among the subpopulations.Interestingly,population genetic analyses revealed that specific haplotypes of PAL6 and LIN6 have been selected in japonica rice.Based on these results,we propose a possible oil biosynthetic pathway in rice grains.Collectively,our results provide new insights into the genetic basis of oil biosynthesis in rice grains and can facilitate marker-based breeding of rice varieties with enhanced oil and grain quality. | Hao Zhou Duo Xia Pingbo Li Yiting Ao Xiaodong Xu Shanshan Wan Yanhua Li Bian Wu Huan Shi Kaiyue Wang Guanjun Gao Qinglu Zhang Gongwei Wang Jinghua Xiao Xianghua Li Sibin Yu Xingming Lian Yuqing He | 2021 | Molecular Plant2021，14，3： | 4 |

| 13 | Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Pseudomyxoma Peritonei of Appendiceal Origin-801 Cases from a Single Institution in China显示文摘Aim:As more and more centers has published their treatment results of pseudomyxoma peritonei(PMP)with cytoreductive surgery(CRS)and hyperthermic intraperitoneal chemotherapy(HIPEC),the data from China is missing.Myxoma Department of Aerospace Hospital is the biggest center treating PMP in China.The purpose of this study is to report the early and long-term outcomes for PMP from this single center.Methods:801 appendix-derived PMP out of 1008 consecutive patients treated in Myxoma Department of Aerospace Hospital between 2008 and 2019 were retrospectively analyzed.Results:Complete cytoreductive surgery(CCRS)was achieved in 240(30%)patients with median PCI of 14(1~39),and the rest had maximal tumor debulking(MTD),HIPEC was implemented in 96.3%of CCRS and 78.6%of MTD.The major morbidity(grade III/IV)was 11.4%and the 30-day operative mortality is 0.7%.The 5-and 10-year OS of CCRS was 76.9%and 64.1%,which is significantly higher than MTD(5-,10-year OS as 36.1%,27.1%;p<0.001).On the univariate analysis,all prognostic factors(gender,PSS,interval time,prior chemotherapy,prior HIPEC,Peritoneal Cancer Index(PCI),completeness of cytoreduction(CC),HIPEC,pathology,present of serous ascites)were found to be associated with overall survival except for age.On multivariate analysis,only PCI>20,MTD,high pathologic grade and without HIPEC were independent factors predicting poorer prognosis.Conclusions:CCRS+HIPEC can benefit PMP well with controllable risks.MTD+HIPEC may benefit PMP as well when CCRS cannot be achieved after fully asscessment by an experienced peritoneal maglignacy center,but the surgery should be performed as limited as possible. | Ao Xia Xichao Zhai Lubiao An Bing Wang Guanjun Shi Ying Cai Yiyan Lu Shaojun Pang Feng Chen Hongbin Xu Ruiqing Ma | 2020 | Journal of Oncology Research2020，2，2： | 0 |
| 14 | Tensor-Based Source Localization Method with EVS Array显示文摘In many wireless scenarios,e.g.,wireless communications,radars,remote sensing,direc-tion-of-arrival(DOA)is of great significance.In this paper,by making use of electromagnetic vec-tor sensors(EVS)array,we settle the issue of two-dimensional(2D)DOA,and propose a covari-ance tensor-based estimator.First of all,a fourth-order covariance tensor is used to formulate the array covariance measurement.Then an enhanced signal subspace is obtained by utilizing the high-er-order singular value decomposition(HOSVD).Afterwards,by exploiting the rotation invariant property of the uniform array,we can acquire the elevation angles.Subsequently,we can take ad-vantage of vector cross-product technique to estimate the azimuth angles.Finally,the polarization parameters estimation can be easily completed via least squares,which may make contributions to identifying polarization state of the weak signal.Our tensor covariance algorithm can be adapted to spatially colored noise scenes,suggesting that it is more flexible than the most advanced algorithms.Numerical experiments can prove the superiority and effectiveness of the proposed approach. | Guanjun Huang Yongquan Li Zijing Zhang Junpeng Shi Fangqing Wen | 2021 | Journal of Beijing Institute of Technology2021，30，4： | 0 |
| 15 | Nondestructive identification of softness via bioinspired multisensory electronic skins integrated on a robotic hand显示文摘Tactile sensing is essentially required for dexterous manipulation in robotic applications.Mimicking human perception of softness identification in a non-invasive fashion,thus achieving satisfactory interaction with fragile objects remains a grand challenge.Here,a scatheless measuring methodology based on the multisensory electronic skins to quantify the elastic coefficient of soft materials is reported.This recognition approach lies in the preliminary classification of softness by piezoelectric signals with a modified machine learning algorithm,contributing to an appropriate contact force assignment for subsequent quantitative measurements via strain sensing feedback.The integration of multifunctional sensing system allows the manipulator to hold capabilities of selfsensing and adaptive grasping motility in response to objects with the various softness(i.e.,kPa-MPa).As a proof-of-concept demonstration,the biomimetic manipulator cooperates with the robotic arm to realize the intelligent sorting of oranges varying in freshness,paving the way for the development of microsurgery robots,human-machine interfacing,and advanced prosthetics. | Ye Qiu Shenshen Sun Xueer Wang Kuanqiang Shi Zhiqiang Wang Xiaolong Ma Wenan Zhang Guanjun Bao Ye Tian Zheng Zhang Hao Ding Hao Chai Aiping Liu Huaping Wu | 2022 | npj Flexible Electronics2022，6，1： | 0 |
| 16 | Recognition System for Diagnosing Pneumonia and Bronchitis Using Children’s Breathing Sounds Based on Transfer Learning显示文摘Respiratory infections in children increase the risk of fatal lung disease,making effective identification and analysis of breath sounds essential.However,most studies have focused on adults ignoring pediatric patients whose lungs are more vulnerable due to an imperfect immune system,and the scarcity of medical data has limited the development of deep learning methods toward reliability and high classification accuracy.In this work,we collected three types of breath sounds from children with normal(120 recordings),bronchitis(120 recordings),and pneumonia(120 recordings)at the posterior chest position using an off-the-shelf 3M electronic stethoscope.Three features were extracted from the wavelet denoised signal:spectrogram,mel-frequency cepstral coefficients(MFCCs),and Delta MFCCs.The recog-nition model is based on transfer learning techniques and combines fine-tuned MobileNetV2 and modified ResNet50 to classify breath sounds,along with software for displaying analysis results.Extensive experiments on a real dataset demonstrate the effectiveness and superior performance of the proposed model,with average accuracy,precision,recall,specificity and F1 scores of 97.96%,97.83%,97.89%,98.89%and 0.98,respectively,achieving superior performance with a small dataset.The proposed detection system,with a high-performance model and software,can help parents perform lung screening at home and also has the potential for a vast screening of children for lung disease. | Jianying Shi Shengchao Chen Benguo Yu Yi Ren Guanjun Wang Chenyang Xue | 2023 | Intelligent Automation & Soft Computing2023，37，9： | 0 |
| 17 | Enhanced figure of merit for famatinite Cu_(3)SbSe_(4)via band structure tuning and hierarchical architecture显示文摘The p-type Te-free Cu_(3)SbSe_(4)with famatinite structure is a potential candidate for thermoelectric materials due to the low cost and eco-friendly constituent elements.However,its strong bipolar effect and high lattice thermal conductivity(klat)are the main challenges for its performance enhancement.Herein,we report a new strategy to enhance its figure of merit zT~0.86 at 673 K for Cu_(3)Sb_(0.95)Fe_(0.05)Se_(2.8)S_(1.2)via band structure tuning and hierarchical architecture.Firstly,S substituted Se atoms in lattice can widen the band gap to alleviate the bipolar effect.Secondly,Fe doping in Sb site significantly increases the density of states,thus increasing the carrier effective mass,and obtaining a remarkably high Seebeck coefficient of~560 mV/K at 300 K.Moreover,the induced hierarchical architecture defects resulting in a minimum klat of~0.48 W·m^(-1)·K^(-1)at 673 K.Consequently,the improved Seebeck coefficient combined with low thermal conductivity leads to an enhanced zT. | Lijun Zhao Haolin Ye Xinmeng Wu Jian Yang Lihua Yu Zhongqi Shi Shahid Hussain Guanjun Qiao Junhua Xu Bangzhi Ge Li Wang Chongjian Zhou | 2023 | Journal of Materiomics2023，9，6： | 0 |
