2Color image detail enhancement based on quaternion guided filter显示文摘Color image enhancement is an active research field in image processing. Currently, many image enhancement methods are capable of enhancing the details of the color image. However, these methods only process the red, green and blue(RGB) color channels separately, which leads to color distortion easily. In order to overcome this problem, the paper presents an approach to integrate the quaternion theory into the traditional guided filter to obtain a quaternion guided filter(QGF). This method makes full use of the color information of an image to realize the holistic processing of RGB color channels. So as to preserve color information while enhancing details, this paper proposes a color image detail enhancement algorithm based on the QGF. Experimental results show that the proposed algorithm is effective in the applications of the color image detail enhancement, and enables image's edges to be more prominent and texture clearer while avoiding color distortion. Compared with the existing image enhancement methods, the proposed method achieves better enhancement performance in terms of the visual quality and the objective evaluating indicators.Wu Kun Li Guiju Han Guangliang Yang Hang Liu Peixun 2017The Journal of China Universities of Posts and Telecommunications2017,24,4:3
3Fabrication and near-infrared optical responses of 2D periodical Au/ITO nanocomposite arrays显示文摘Two-dimensional(2D) periodical Au and indium tin oxide(ITO) nanocomposite arrays have been fabricated based on a self-assembled nanosphere lithography technique. A button-shaped Au nanoparticle was formed on each hollow hemisphere-shaped ITO shell. Importantly, the underlying formation mechanism during the thermal treatment has been thoroughly explored by comparing structures resulting from different deposition conditions in detail. Compared to the Au nanoparticle arrays without ITO shells, the Au/ITO nanocomposite arrays showed a stronger localized surface plasmon resonance effect and higher absorption in the near-infrared(NIR) region, benefiting from the free-electron interaction enhancement between Au and ITO. The nonlinear optical properties were investigated using a modified femtosecond intensity-scan system, and the results demonstrated Au/ITO nanocomposite arrays with a remarkable two-photon absorption saturation effect for femtosecond pulses at 1030 nm. The versatile NIR optical responses indicate the great potential of the elaborately prepared 2D periodical Au/ITO nanocomposite arrays in many applications such as solar cells, photocatalysis,and novel nano optoelectronic devices.ZHENGYUAN BAI GUIJU TAO YUANXIN LI JIN HE KANGPENG WANG GAOZHONG WANG XIONGWEI JIANG JUN WANG WERNER BLAU LONG ZHANG 2017Photonics Research2017,5,4:2
4Distribution and spectral characteristics of chromophoric dissolved organic matter in a coastal bay in northern China显示文摘The absorption spectra of chromophoric dissolved organic matter(CDOM),along with general physical,chemical and biological variables,were determined in the Bohai Bay,China,in the springs of 2011 and 2012. The absorption coefficient of CDOM at 350 nm(a350) in surface water ranged from 1.00 to 1.83 m-1(mean: 1.35 m-1) in May 2011 and from 0.78 to 1.92 m-1(mean:1.19 m-1) in April 2012. Little surface-bottom difference was observed due to strong vertical mixing. The a350 was weakly anti-correlated to salinity but positively correlated to chlorophyll a(Chl-a) concentration. A shoulder over 260–290 nm,suggestive of biogenic molecules,superimposed the overall pattern of exponentially decreasing CDOM absorption with wavelength. The wavelength distribution of the absorption spectral slope manifested a pronounced peak at ca. 300 nm characteristic of algal-derived CDOM. All a250/a365 ratios exceeded 6,corresponding to CDOM molecular weights(Mw) of less than 1 kDa. Spectroscopically,CDOM in the Bohai Bay differed substantively from that in the Haihe River,the bay's dominant source of land runoff; photobleaching of the riverine CDOM enlarged the difference.Results point to marine biological production being the principal source of CDOM in the Bohai Bay during the sampling seasons. Relatively low runoff,fast dilution,and selective photodegradation are postulated to be among the overarching elements responsible for the lack of terrigenous CDOM signature in the bay water.Guiju Li Jing Liu Yulan Ma Ruihua Zhao Suzheng Hu Yijie Li Hao Wei Huixiang Xie 2014Journal of Environmental Sciences2014,26,8:2

6Comparative proteomic analysis of cold responsive proteins in two wheat cultivars with different tolerance to spring radiation frost显示文摘Spring radiation frost(SRF)is a severe environmental stress which impairs wheat yield and productivity worldwide.To better understand the mechanism of wheat(Triticum aestivum)responding to SRF,a comparative proteomic analysis was performed to analyze the changes of the key proteins in two wheat cultivars Jimai22 and Luyuan301 with high and low tolerance to SRF respectively.A total of 43 differentially expressed proteins(DEPs)which mainly involved in carbohydrate metabolism,amino acid metabolism,resistance proteins and antioxidant enzymes,photosynthesis and cellular respiration proteins,cell-wall related proteins,protein translation/processing/degradation and signal transduction were isolated and identified by two-dimensional electrophoresis and MALDI-TOF-TOF MS.The results revealed that of the 21 DEPs in Jimai22 responding to the SRF,13 DEPs were upregulated and 8 DEPs were downregulated,and that of the 22 DEPs in Luyuan301,9 DEPs were upregulated and 13 DEPs were downregulated.These DEPs might be responsible for the stronger cold resistance of Jimai22 compared to Luyuan301.The expression pattern and function analysis of these DEPs were very significant to understanding the mechanism of the SRF responses in wheat.Shujuan ZHANG Guoqi SONG Yulian LI Jie GAO Jiao WANG Guiju CHEN Haosheng LI Genying LI Zhendong ZHAO 2014Frontiers of Agricultural Science and Engineering2014,1,1:1

8The association between folic acid supplementation,maternal folate during pregnancy and intelligence development in infants:a prospective cohort study显示文摘Objective The study aimed to explore the association between folic acid supplementation,maternal nutritional levels during pregnancy and intelligence development of infants.Method This was a prospective cohort study,mothers and their offspring in Jurong Maternal and Child Health Hospital were followed up through pregnancy up to 1 year.The basic information of pregnant women was obtained through questionnaire survey,including pregnancy lifestyle,marital status,vitamin and mineral supplements during pregnancy.Blood samples of pregnant women were collected on admission,serum folate,vitamin B12 and homocysteine concentrations were determined.Maternal postpartum colostrum was collected and the concentrations of folate and vitamin B12 in colostrum were determined.Pregnant women(n=478)and their corresponding infants were followed up and the Developmental Screen Test scores were recorded at 1,3,6,8 and 12 months of age.Results Compared with the normal group,infants in the low serum folate group had a score of 0.12 points lower in the intellectual energy zone(95%CI:-0.23–-0.01,P=0.04),and infants with the high homocysteine level scored 1.30 points lower than the lower-level group(95%CI:-2.52–-0.08,P=0.04).In the colostrum low-vitamin B12 level group,infants scored 0.10 points lower(95%CI:-1.84–-0.02,P=0.02)in the social adaptation zone compared to the normal group.Conclusion In conclusion,folic acid supplementation in the pre-pregnancy supplementation group and the post-pregnancy supplementation group may be not associated with infant mental development.In addition,maternal folate and homocysteine may be related to the intellectual development of infants.The level of vitamin B_(12)in colostrum may be associated with infants’social adaptive capacity.This result may be caused by individual differences in folate and homocysteine metabolism in pregnant women.Shaokang Wang Jie Wei Di Wang Li Hua Da Pan Lingmeng Fu Jin Yang Guiju Sun 2021Food Science and Human Wellness2021,10,2:0
9Insight into the boosted activity of TiO2–CoP composites for hydrogen evolution reaction:Accelerated mass transfer,optimized interfacial water,and promoted intrinsic activity显示文摘The use of abundant elements in the earth as electrocatalytic hydrogen production catalysts is of great significance for hydrogen energy cycling.Herein,we report amorphous TiO_(2)-decorated CoP/NF(TiO_(2)–CoP/NF)as an excellent electrocatalyst for alkaline hydrogen evolution reaction(HER).The welldispersed amorphous TiO_(2)on nanoneedle-like CoP arrays preserves the crystal structure of CoP and changes its electronic structure by interfacial charge transfer.Compared to CoP/NF catalyst,the Ti O_(2)–CoP/NF composite catalyst exhibits high HER activity with an overpotential of 61 mV at 10 mA cm^(-2)and high stability.Importantly,it almost maintains the Volmer step as a rate-determining step(RDS)and the Tafel slope at a wide cathodic potential range showing the fast kinetics under large polarization regions.Theoretical simulations reveal that the combination of TiO_(2)and CoP selectively accelerates the hydrated K+diffusion,regulates the interfacial water orientation to adapt to the subsequent smooth water dissociation,and optimizes*H adsorption/H_(2)desorption.The strengthened coupling of HER multi-scale-processes on transition metal compound composites catalysts is the underlying mechanism for improving HER activity.Mingming Deng Hongmei Yang Lishan Peng Ling Zhang Lianqiao Tan Guiju He Minhua Shao Li Li Zidong Wei 2022Journal of Energy Chemistry2022,31,11:0
