| 1 | Wavelet denoising via sparse representation显示文摘Wavelet threshold denoising is a powerful method for suppressing noise in signals and images. However, this method often uses a coordinate-wise processing scheme, which ignores the structural properties in the wavelet coefficients. We propose a new wavelet denoising method using sparse representation which is a powerful mathematical tool recently developed. Instead of thresholding wavelet coefficients individually, we minimize the number of non-zero coefficients under certain conditions. The denoised signal is reconstructed by solving an optimization problem. It is shown that the solution to the optimization problem can be obtained uniquely and the estimates of the denoised wavelet coefficients are unbiased, i.e., the statistical means of the estimates are equal to the noise-free wavelet coefficients. It is also shown that at least a local optimal solution to the denoising problem can be found. Our experiments on test data indicate that this new denoising method is effective and efficient for a wide variety of signals including those with low signal-to-noise ratios. | ZHAO RuiZhen LIU XiaoYu Ching-Chung LI Robert J.

| 3 | Derivation of Putative Porcine Embryonic Germ Cells and Analysis of Their Multi-Lineage Differentiation Potential显示文摘Embryonic germ(EG)cells are cultured pluripotent stem cells derived from the primordial germ cells(PGCs)that migrate from the dorsal mesentery of the hindgut to the developing genital ridge.In this study,the morphology of the porcine genital ridge was assessed in embryos harvested on days 22-30 of pregnancy.PGCs from embryos at these stages were cultured to obtain porcine EG cell lines,and EG-like cells were derived from PGCs from embryos harvested on days 24-28 of pregnancy.The EG-like cells expressed Oct4,Sox2,Nanog,SSEA-3,SSEA-4 and alkaline phosphatase(AP).These cells were able to form embryoid bodies(EBs)in suspension culture and differentiate into cells representative of the three germ layers as verified by a-fetoprotein(AFP),a-smooth muscle actin(a-SMA),and Nestin expression.Spontaneous differentiation from the porcine EG-like cells of delayed passage in vitro showed that they could differentiate into epithelial-like cells,mesenchymal-like cells and neuron-like cells.In vitro directed differentiation generated osteocytes,adipocytes and a variety of neural lineage cells,as demonstrated by alizarin red staining,oil red O staining,and immunofluorescence for neuronal classⅢb-tubulin(Tuj1),glial fibrillary protein(GFAP)and galactosylceramidase(GALC),respectively.These results indicate that porcine EG-like cells have the potential for multi-lineage differentiation and are useful for basic porcine stem cell research. | Yimei Cong Jing Ma Ruizhen Sun Jianyu Wang Binghua Xue Jiaqiang Wang Bingteng Xie Juan Wang Kui Hu Zhonghua Liu | 2013 | Journal of Genetics and Genomics2013，40，9： | 4 |
| 4 | Detection of Thermophysical Properties for High Strength Concrete after Exposure to High Temperature显示文摘Using the detection principle of infrared thermal imaging technique and the detection principle of DRH thermal conductivity tester laboratory,we investigated the infrared thermal image inspection,coefficient of thermal conductivity,apparent density,and compressive strength test on C80 high-strength concrete(HSC) in the presence and absence of polypropylene fibers under completely heated conditions.Only slight damages were detected below 400 ℃,whereas more and more severe deterioration events were expected when the temperature was above 500 ℃.The results show that the elevated temperature through infrared images generally exhibits an upward trend with increasing temperature,while the coefficient of thermal conductivity and apparent density decrease gradually.Additionally,the addition of polypropylene fibers with appropriate length,diameter,and quantity contributes to the improvement of the high-temperature resistance of HSC. | 杜红秀 WU Jia LIU Gaili WU Huiping YAN Ruizhen | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，1： | 3 |
| 5 | CT Image-based Analysis on the Defect of Polypropylene Fiber Reinforced High-Strength Concrete at High Temperatures显示文摘With the application of X-ray computed tomography(CT) technology of C80 high-strength concrete with polypropylene fiber at elevated temperatures, the microscopic damage evolution process observation and image building could be obtained, based on the statistics theory and numerical analysis of the combination of concrete internal defects extension and evolution regularity of microscopic structure. The expermental results show that the defect rate has changed at different temperatures and can determine the concrete degradation threshold temperatures. Also, data analysis can help to establish the evolution equation between the defect rate and the effect of temperature damage, and identify that the addition of polypropylene fibers in the high strength concrete at high temperature can improve cracking resistance. | 杜红秀 JIANG Yu LIU Gaili YAN Ruizhen | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，4： | 2 |
| 6 | A composite of Ni-Fe-Zn layered double hydroxides/biochar for atrazine removal from aqueous solution显示文摘This study assembled corn stalk-derived biochar(BC)with layered double hydroxide(LDH)through a rapid coprecipitation of biochar and metal(Ni/Fe/Zn)hydroxide precipitates.A BC and LDH composite(BC-LDH)and modified BC-LDH material after heating(BC-LDH-P)were prepared successfully for atrazine adsorptive removal.The physicochemical properties of the synthesized samples were analyzed by X-ray diffraction(XRD),scanning electron microscopy(SEM),Fourier transform infrared(FT-IR),and X-ray photoelectron spectroscopy(XPS).Batch experiments were conducted to study the sorption of atrazine onto BC,BC-LDH,and BC-LDH-P from the aqueous solution.The adsorption of atrazine onto BC-LDH and BC-LDH-P were performed following with the pseudo-second-order kinetic model,and the sorption isotherms agreed well with the Freundlich fitting model.The adsorption amounts of the three materials are arranged in descending order is as follows:BC-LDH-P>BC-LDH>BC(143.15>123.10>95.93 mg g−1,respectively).Due to the high crystallinity of the LDH material and the high binding degree with biochar,Ni/Fe/Zn-LDH biochar composites offer a potential alternative to a carbon-based adsorbent for atrazine removal from aqueous solution. | Yifan Wang Jiaming Kang Simeng Jiang Hui Li Zheyi Ren Qinbo Xu Qun Jiang Wenzhu Liu Ruizhen Li Ying Zhang | 2020 | Biochar2020，2，4： | 2 |

| 11 | Fine Mapping of QTLs for Stigma Exsertion Rate from Oryza glaberrima by Chromosome Segment Substitution显示文摘Stigma exsertion is an important trait for outcrossing ability in rice.Stigma exsertion rate(SER)of male sterile lines(MSLs)is a key factor affecting F1-seed production in hybrid rice.In this study,seven QTLs for SER were detected on five chromosomes using a set of single-segment substitution lines(SSSLs)derived from O.glaberrima.Three of the QTLs were mapped in the estimated intervals of 92.5–333.0 kb.qSER-5 was located in a substitution segment of 92.5 kb.qS ER-1 b and qS ER-8 b were respectively limited to 333.0 kb and 107.5 kb by secondary substitution mapping.qSER-1 b and qSER-3 had bigger additive effects of 11.5%and 11.9%,respectively,while the other five QTLs had smaller additive effects from 5.7%to 8.6%.Open reading frames were identified in the regions of qS ER-5 and qSER-8 b in O.sativa and O.glaberrima genomes.Fine mapping of the QTLs laid a foundation for the cloning of genes,and QTLs for SER will be used to develop MSLs with strong ability of outcrossing. | TAN Quanya ZHU Haitao LIU Hui NI Yuerong WU Shengze LUAN Xin LIU Junwei YANG Weifeng YANG Zifeng ZENG Ruizhen LIU Guifu WANG Shaokui ZHANG Guiquan | 2022 | Rice science2022，29，1： | 1 |

| 14 | Wheat male-sterile 2 reduces ROS levels to inhibit anther development by deactivating ROS modulator 1显示文摘Ms2 is an important dominant male-sterile gene in wheat,but the biochemical function of Ms2 and the mechanism by which it causes male sterility remain elusive.Here,we report the molecular basis underlying Ms2-induced male sterility in wheat.We found that activated Ms2 specifically reduces the reactive oxygen species(ROS)signals in anthers and thereby induces termination of wheat anther development at an early stage.Furthermore,our results indicate that Ms2 is localized in mitochondria,where it physically interacts with a wheat homolog of ROS modulator 1(TaRomo1).Romo1 positively regulates the ROS levels in humans but has never been studied in plants.We found that single amino acid substitutions in the Ms2 protein that rescue the ms2 male-sterile phenotype abolish the interaction between Ms2 and TaRomo1.Significantly,Ms2 promotes the transition of TaRomo1 proteins from active monomers to inactive oligomers.Taken together,our findings unravel the molecular basis of Ms2-induced male sterility and reveal a regulatory mechanism in which ROS act as essential signals guiding the anther development program in wheat. | Jie Liu Chuan Xia Huixue Dong Pan Liu Ruizhen Yang Lichao Zhang Xu Liu Jizeng Jia Xiuying Kong Jiaqiang Sun | 2022 | Molecular Plant2022，15，9： | 1 |
