    Improvement of the Economic Management System Based on the Publicity of Railway Transportation Products

    Bai Yan*

    Intelligent Automation & Soft Computing, Vol.26, No.3, pp. 539-547, 2020, DOI:10.32604/iasc.2020.013931

    Abstract The traditional view is that due to the natural monopoly and external publicity of the railway transportation, the economic regulation should have been implemented. However, due to the inaccurate grasp of the technical and economic characteristics of various components in the system and the current social and economic situation in China, the economic regulation has been implemented for a long time. Based on a detailed analysis of the characteristics of the railway transportation infrastructure and the market characteristics of the road transportation products, combined with China's actual national conditions, the economic regulation schemes for each market segment have been proposed… More >

    Optimal Tuning for Load Frequency Control Using Ant Lion Algorithm in Multi‐Area Interconnected Power System

    Nour EL Yakine Koubaa, Mohamed Menaaa, Kambiz Tehranib, Mohamed Boudoura

    Intelligent Automation & Soft Computing, Vol.25, No.2, pp. 279-294, 2019, DOI:10.31209/2018.100000007

    Abstract This paper presents the use of a novel nature inspired meta-heuristic algorithm namely Ant Lion Optimizer (ALO), which is inspired from the ant lions hunting mechanism to enhance the frequency regulation and optimize the load frequency control (LFC) loop parameters. The frequency regulation issue was formulated as an optimal load frequency control problem (OLFC). The proposed ALO algorithm was applied to reach the best combination of the PID controller parameters in each control area to achieve both frequency and tie-line power flow exchange deviations minimization. The control strategy has been tested firstly with the standard two-area power system, followed by… More >

    Regulation of mouse embryo development by autocrine throphic factors

    M.T. TERUEL1,2, R.C. CATALANO2, J.A. CABODEVILA2, S.S. CALLEJAS2

    BIOCELL, Vol.29, No.2, pp. 183-186, 2005, DOI:10.32604/biocell.2005.29.183

    Abstract Embryo development depends on maternal and embryonic factors. When occurs in vitro, embryos secrete factors that stimulate their development. The purpose of this study was to investigate the possible effects of embryos at morula stage on mouse embryo development in vitro. To obtain conditioned media (CM), morulas were cultured in groups of 5 (CM5) or 10 (CM10) in microdrops of Ham-F10 culture medium during 24 h and later they were removed. Subsequently, 365 morulas were cultured in CM5 and CM10 or in Ham-F10 media (as control group). No differences in blastocyst formation could be found between embryos cultured for 24h… More >

    Abscisic acid biosynthesis and catabolism and their regulation roles in fruit ripening

    Yang FW, XQ Feng

    Phyton-International Journal of Experimental Botany, Vol.84, No.2, pp. 444-453, 2015, DOI:10.32604/phyton.2015.84.444

    Abstract Abscisic acid (ABA) plays a series of significant physiology roles in higher plants including but not limited to promote bud and seed dormancy, accelerate foliage fall, induce stomatal closure, inhibit growth and enhance resistance. Recently, it has been revealed that ABA also has an important regulator role in the growth, development and ripening of fruit. In higher plants ABA is produced from an indirect pathway from the cleavage products of carotenoids. The accumulation of endogenous ABA levels in plants is a dynamic balance controlled by the processes of biosynthesis and catabolism, through the regulation of key ABA biosynthetic gene and… More >

    ABSTRACT

    The Dependence of Diffusio-Phoretic Mobility and Aggregation Properties of Proteins on Intermolecular Interaction in Confined System

    Jiachen Wei1,2,*

    Molecular & Cellular Biomechanics, Vol.16, Suppl.2, pp. 103-104, 2019, DOI:10.32604/mcb.2019.07721

    Abstract Phoretic flow can be generated by different types of gradient (e.g. temperature, concentration, or charge gradient) [1-3]. Within micro-to-nano confined system, the diffusio-phoretic property for proteins differs dramatically from that obtained in bulk condition, due to concentration fluctuation that emerges at microscopic level induced by specific and nonspecific interactions between protein and co-solute [4-5]. The phoretic mobility of protein individuals and complex in solute gradients can be theoretically described by continuum model [1-2] that neglects microscopic heterogeneity and determined experimentally by microfluidics [6], but the underlying mechanism of diffusio-phoretic motion for confined protein still remains unclear.

    UPFC Based Real-Time Optimization of Power Systems for Dynamic Voltage Regulation

    Serhat Berat Efe1,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.116, No.3, pp. 391-406, 2018, DOI:10.31614/cmes.2018.01784

    Abstract Flexible alternating current transmission system (FACTS) components are used to utilize the electrical transmission lines at their optimum capacity. The best way to achieve this optimization is to manage the active and reactive power flows. A unified power flow controller (UPFC) is one of the most significant devices developed for the effective control of power flows. Although conventional UPFC structures can be used to achieve this process, the expansion of power systems has led to the necessity of developing various UPFC devices. This paper focuses on an advanced real time control approach of UPFC for dynamic voltage regulation. The developed… More >

    The Mechanochemical Basis of Cell and Tissue Regulation

    D.E. Ingber1

    Molecular & Cellular Biomechanics, Vol.1, No.1, pp. 53-68, 2004, DOI:10.3970/mcb.2004.001.053

    Abstract This article is a summary of a lecture presented at a symposium on "Mechanics and Chemistry of Biosystems'' in honor of Professor Y.C. Fung that convened at the University of California, Irvine in February 2004. The article reviews work from our laboratory that focuses on the mechanism by which mechanical and chemical signals interplay to control how individual cells decide whether to grow, differentiate, move, or die, and thereby promote pattern formation during tissue morphogenesis. Pursuit of this challenge has required development and application of new microtechnologies, theoretical formulations, computational models and bioinformatics tools. These approaches have been used to… More >

    Down-regulation of Halr1 during induced differentiation of embryonal carcinoma P19 cells

    Zahra HOSSEININIA1, Sara SOLTANIAN2, Naser MAHDAVI-SHAHRI3, Hesam DEHGHANI1,4

    BIOCELL, Vol.43, No.3, pp. 145-154, 2019, DOI:10.32604/biocell.2019.06468

    Abstract Maintenance of pluripotency depends to diverse regulatory factors. Studies in embryonic stem cells (ESCs) have indicated that large intergenic non-coding RNAs (lincRNAs) are involved in the regulatory network of pluripotency. However, the presence and function of pluripotency-associated lincRNAs in cancer cells with pluripotency features are unknown. In this study, we used embryonal carcinoma (EC) P19 cell lines to investigate the expression level of Halr1 in pluripotency and retinoic acid (RA)-induced differentiated states. Down-regulation of pluripotency associated factors such as OCT4, NANOG, SSEA1 and alkaline phosphatase at transcript and protein levels were used to confirm the differentiated status of P19 cells.… More >

    mRNA-specific translational regulation in yeast

    Bengü ERGÜDEN

    BIOCELL, Vol.43, No.3, pp. 103-118, 2019, DOI:10.32604/biocell.2019.06517

    Abstract The expression of a gene is governed at various levels, from transcriptional to translational level. The translational control is widely used to regulate gene expression, especially when a rapid, local, and selective control over protein synthesis is required. The present review describes instructive examples of translational regulation in yeast, together with regulatory elements within mRNAs. The review also outlines the important contributions of mRNAbinding proteins that act in harmony with several translational elements to generate appropriate translational signals and responses.
