Ant colony algorithm (ACA) is a new heuristic algorithm which has been proven a successful technique and applied to a number of combinatorial optimization problems. An Granular ACA algorithm based on scout characteristic is proposed for solving the stagnation behavior and premature convergence problem of the basic ACA algorithm on TSP. Proposesing a Granular computing adaptive ant pheromones mechanism base on researching on ant colony algorithm model, pheromones update and pheromones selection had been improved. Make up the traditional ant colony algorithm for the calculation of distribution network planning that is slow and easy to fall into local optimal solution. And improved the convergence of the optimal solution. The validity of the GACA has been verified using a testing function. In addition, a satisfactory optimum solution for a Power Distribution Network Planning that has 73 users has been obtained.

Zhu Shi Wei,Zhang Xiao Guo,Lv Jia Dong,Wang Qing 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.1

Aiming at solving problem of points’ redundancy caused by full automatically detecting points and the problem of large workload caused by picking all points manually, I advanced a new method of picking points which is based on Human-Computer Interaction in our 3D reconstruction platform after automatically detecting points. We first detected and matched points automatically and got the homograph matrix between two images, then projected points which were picked by hand on the one image to the other image, at last we would search the interesting feature points in the neighborhood of corresponding points in the two images. Experiments have shown that this method decreases the redundancy brought by large number of points and successfully finds the important feature points, so it lays a good foundation for 3D reconstruction.

Zhu, Lei,Tang, Jia-Yao,Fan, Jia-Yi,Sun, Chen,Meng, Ze-Da,Oh, Won-Chun Materials Research Society of Korea 2021 한국재료학회지 Vol.31 No.11

Herein, a series of g-C₃N₄ modified Bi₂MoO₆ nanocomposites using Bi₂MoO₆ and melamine as original materials are fabricated via sintering process. For presynthesis of Bi₂MoO₆ an ultrasonic-assisted hydrothermal technique is researched. The structure and composition of the nanocomposites are characterized by Raman spectroscopy, X-ray diffraction (XRD), and high-resolution field emission scanning electron microscopy (SEM). The improved photoelectrochemical properties are studied by photocurrent density, EIS, and amperometric i-t curve analysis. It is found that the structure of Bi₂MoO₆ nanoparticles remains intact, with good dispersion status. The as-prepared g-C₃N₄/Bi₂MoO₆ nanocomposites (BMC 5-9) are selected and investigated by SEM analysis, which inhibits special morphology consisting of Bi₂MoO₆ nanoparticles and some g-C₃N₄ nanosheets. The introduction of small sized g-C₃N₄ nanosheets in sample BMC 9 is effective to improve the charge separation and transfer efficiency, resulting in enhancing of the photoelectric behavior of Bi₂MoO₆. The improved photoelectronic behavior of g-C₃N₄/Bi₂MoO₆ may be attributed to enhanced charge separation efficiency, photocurrent stability, and fast electron transport pathways for some energy applications.

The Liangshan pig is a traditional Chinese small-sized breed; it has a relatively long feeding period and low meat production ability but superior meat quality. This study utilized three non-linear growth models (Von Bertalanffy, Gompertz, and logistic) to fit the growth curve of Liangshan pigs from an unselected, random-bred pig population and estimate the pigs most suitable slaughter weight. The growth development data at 20 time points of 275 Liangshan pigs (from birth to 250 d) were collected. To analyze the relative gene expression related to development, seven slaughter weight phases (50, 58, 66, 74, 82, 90, and 98 kg) (20 pigs per phase) were examined. We found that the Liangshan pig growth curve fit the typical S-curve well and that their growth turning point was 193.4 days at a weight of 62.5 kg, according to the best fit Von Bertalanffy model based on the goodness of fit criteria. Furthermore, we estimated that the most suitable slaughter weight was 62.5 to 74.9 kg based on the growth curve and the relative expression levels of growth-related genes.

Zhu Si-jia,Wang Rui-ting,Yu Ze-yu,Zheng Ruo-Xiang,Liang Chang-Hao,Zheng You-you,Fang Min,Han Mei,Liu Jian-ping 한국한의학연구원 2022 Integrative Medicine Research Vol.11 No.2

Background: Myasthenia Gravis (MG) is a disorder of neuromuscular transmission bringing mild ocular weakness to severe generalized muscle weakness and disability. The conventional treatments have longterm side effects, and Chinese herbal medicines (CHM) have shown possible effect and safety for MG patients, but the existing evidence was not robust enough and the results were out of date. Methods: Searching for randomized controlled trials (RCTs) was conducted in 7 databases and clinical trial registries until July 2021. The Risk of Bias (ROB) 2 tool was used to assess the study quality and GRADE was used to assess the quality of whole evidence. Meta-analyses were conducted and the results were presented as risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI). Results: Nineteen RCTs (1283 participants) testing 13 kinds of CHM with adequate randomization were included and six RCTs investigating Compound Huangqi were included in the meta-analyses. In addition to conventional treatment, nine CHMs reduced symptom scores of MG. Compound Huangqi plus conventional treatment (pyridostigmine bromide or prednisone or both) reduced the symptom scores compared with conventional treatment (MD=-3.56, 95%CI -4.86 to -2.26). Less adverse events happened in the CHM groups (3/247 in the CHM groups, 52/245 in the control groups, RR=0.13, 95%CI 0.06 to 0.30, 9RCTs, a total of 492 participants). The effect on quality of life was inconsistent. Conclusion: Nine CHMs could probably bring benefit for MG symptom improvement. Moderate to low certainty of evidence supported Compound Huangqi added-on conventional treatment probably bring extra benefit of improving MG symptoms. Adding CHMs could be safer than giving only conventional treatment. Study registration: The protocol was registered in PROSPERO (CRD42016032718).

Analysis of the roles of interphase, waviness and agglomeration of CNT in the electrical conductivity and tensile modulus of polymer/CNT nanocomposites by theoretical approaches

Zhu, Jia-Ming,Zare, Yasser,Rhee, Kyong Yop Elsevier 2018 Colloids and surfaces. A, Physicochemical and engi Vol.539 No.-

<P><B>Abstract</B></P> <P>This study focuses on the roles of interphase between polymer matrix and CNT, waviness and agglomeration of CNT on the electrical conductivity and tensile modulus of polymer/CNT nanocomposites (PCNT). Several simple equations for percolation threshold, effective volume fraction of CNT and the fraction of networked CNT above percolation threshold are expressed assuming the roles of the mentioned parameters. After that, two proper models are applied to express the conductivity and modulus of PCNT by the influences of interphase, waviness and agglomeration. Both conductivity and modulus show similar correlations with these parameters. It is shown that interphase thickness (t), electrical conduction of CNT (σ<SUB>N</SUB>) and modulus of CNT network (E<SUB>N</SUB>) largely affect the electrical conductivity and tensile modulus of PCNT. The best relative conductivity (ratio of PCNT conductivity to polymer conduction) as 14*10<SUP>17</SUP> is achieved by the highest levels of t=20nm and σ<SUB>N</SUB> =2.5*10<SUP>5</SUP> S/m, while t <6nm produces the relative conductivity of 0.3*10<SUP>17</SUP>. Furthermore, the tensile modulus of PCNT improves by 2100% at t=20nm and E<SUB>N</SUB> =1900GPa, whereas about 110% improvement of modulus is shown by t <6nm at different “E<SUB>N</SUB>”.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Conductivity and mechanical performances of polymer CNT nanocomposites are studied. </LI> <LI> The roles of interphase, waviness and agglomeration of CNT are determined. </LI> <LI> Both conductivity and modulus show similar correlations with these parameters. </LI> <LI> Interphase thickness, conduction and modulus of CNT mainly affect the properties of PCNT. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Microwave Assisted Synthesis of Graphene-Bi2MoO6 Nanocomposite as Sono-Photocatalyst

Jia-Yao Tang,Lei Zhu,Jia-Yi Fan,Chen-Sun,Won-Chun Oh 한국재료학회 2022 한국재료학회지 Vol.32 No.1

In this investigation, Bi2MoO6 deposited graphene nanocomposite (BMG) was synthesized using a simple microwave assisted hydrothermal synthesis method. The synthesized BMG nanocomposite was characterized by X-ray diffraction, transmission electron microscopy, scanning electron microscopy with energy dispersive X-ray analysis, and photocurrent analysis. The study revealed that the catalysts prepared have high crystalline nature, enhanced light responsive property, high catalytic activity, and good stability. XRD results of BMG composite exhibit a koechlinite phase of Bi2MoO6. The surface property is shown by SEM and TEM, which confirmed a homogenous composition in the bulk particles of Bi2MoO6 and nanosheets of graphene. The catalytic behavior was investigated by the decomposition of Rhodamine B as a standard dye. The results exhibit excellent yields of product derivatives at mild conditions under ultrasonic/visible light-medium. Approximately 1.6-times-enhanced sono-photocatalytic activity was observed by introduction of Bi2MoO6 on graphene nanosheet compared with control sample P25 during 50 min test.

Upregulation of coleoptericin transcription in Tenebrio molitor parasitized by Scleroderma guani

Jia-Ying Zhu,Guo-Xing Wub,Zhong Zhang 한국응용곤충학회 2014 Journal of Asia-Pacific Entomology Vol.17 No.3

Three antibacterial peptide genes, coleoptericins A, B and C, were identified from the yellow meal worm beetle, Tenebriomolitor. Their cDNA sequences encoded 13.01, 13.13 and 14.16 kDa peptides, respectively. Their deduced amino acid sequences showed 16–34% identity with other coleopteran coleoptericins, containing over 20% glycine. These genes were essentially expressed in fat body and hemocytes, and at late-instar larval and pupal stages. Their transcriptswere upregulated by bacterial challenge and Scleroderma guani parasitization. It suggests that triggered coleoptericin transcription is applied to prevent host potential infection during parasitization.

The F-box Protein KIB1 Mediates Brassinosteroid-Induced Inactivation and Degradation of GSK3-like Kinases in <i>Arabidopsis</i>

Zhu, Jia-Ying,Li, Yuyao,Cao, Dong-Mei,Yang, Hongjuan,Oh, Eunkyoo,Bi, Yang,Zhu, Shengwei,Wang, Zhi-Yong Elsevier 2017 Molecular cell Vol.66 No.5

<P><B>Summary</B></P> <P>The glycogen synthase kinase-3 (GSK3) family kinases are central cellular regulators highly conserved in all eukaryotes. In <I>Arabidopsis</I>, the GSK3-like kinase BIN2 phosphorylates a range of proteins to control broad developmental processes, and BIN2 is degraded through unknown mechanism upon receptor kinase-mediated brassinosteroid (BR) signaling. Here we identify KIB1 as an F-box E3 ubiquitin ligase that promotes the degradation of BIN2 while blocking its substrate access. Loss-of-function mutations of KIB1 and its homologs abolished BR-induced BIN2 degradation and caused severe BR-insensitive phenotypes. KIB1 directly interacted with BIN2 in a BR-dependent manner and promoted BIN2 ubiquitination in vitro. Expression of an F-box-truncated KIB1 caused BIN2 accumulation but dephosphorylation of its substrate BZR1 and activation of BR responses because KIB1 blocked BIN2 binding to BZR1. Our study demonstrates that KIB1 plays an essential role in BR signaling by inhibiting BIN2 through dual mechanisms of blocking substrate access and promoting degradation.</P> <P><B>Highlights</B></P> <P> <UL> <LI> KIB1 is an essential positive regulator in brassinosteroid signaling </LI> <LI> KIB1 mediates BR-induced ubiquitination and degradation of GSK3 kinase BIN2 </LI> <LI> KIB1 binding to BIN2 prevents BIN2-substrate interaction and promotes BIN2 degradation </LI> </UL> </P> <P><B>Graphical Abstract</B></P> <P>[DISPLAY OMISSION]</P>
