COMMON STATIONARY POINTS OF MULTI-VALUED F-CONTRACTIONS WITH δ-DISTANCE
Liu1 Zeqing,Liu Ying,Kang Shin Min 경남대학교 수학교육과 2019 Nonlinear Functional Analysis and Applications Vol.24 No.1
Three common stationary point theorems for some multi-valued F-contractions with δ-distance in bounded complete metric spaces are proved. The results obtained in this paper are extended or are different from several results in the literature. Three nontrivial examples are given.
Study on the Thermal Decomposition of Waste Polystyrene in Motor Oil Using Microwave Energy
Liu, Xiao Yun,Kang, Tae Won 公州大學校 工學硏究院 生産技術硏究所 2003 論文集 Vol.11 No.-
A novel microwave-induced pyrolysis of waste polystyrene in motor oil was performed in quartz tube reactor. Different pyrolysis conditions were investigated, such as time range from 30 minutes to 1 hour and effective microwave power range from 180 to 250 watt. The distillate components were analyzed with GC-MS, and styrene, 1-methyl styrene, toluene, ethyl benzene were the four main products. Among these distillate products, styrene took over 70 percentages. Temperature of pyrolysis suing microwave was much lower than that of conventional thermal pyrolysis method.

In this paper, we introduce and study a class of general strongly nonlinear quasivariational inequalities in Hilbert spaces. We prove the existence and uniqueness of solution and convergence of the perturbed the three-step iterative sequences with errors for this kind of general strongly nonlinear quasivariational inquality problems involving relaxed Lipschitz, relaxed monotone, and strongly monotone mappings. Our results extend, improve, and unify many known results due to Liu-Ume-Kang, Kim-Kyung, Zeng and others.

<P>A total of 60 weaned pigs with initial body weight (BW) of 8.51 ± 0.42 kg (28 d of age) were randomly divided into 2 groups of 30 each consisted of 6 pens with 2 gilts and 3 borrows and supplemented (treatment) 5.3×108 cfu/kg Lactobacillus plantarum GB805 in addition to basal diet offered during d 0 to 14 and d 15 to 42 (control). During the total trial period or different phases of trial, pigs fed L. plantarum diet had a higher (P less than 0.05) ADG, ADFI and feed efficiency. At the end of experiment, dietary L. plantarum supplementation improved (P less than 0.05) the apparent total tract digestibility of dry matter, nitrogen and the fecal Lactobacillus populations (P less than 0.05) while the fecal E.coli populations were decreased (P less than 0.05). In conclusion, dietary supplementation of L. plantarum GB805 had positive influence on growth rate, nutrient digestibility and gut microbial balance and its supplementation recommended to weaning pigs.</P>

sy-2 (Seychelles-2) is a temperature sensitive natural mutant of Capsicum chinense and native to Seychelles Island in Africa. Previously we showed that sy-2 leaves were irregularly shaped and defective in chlorophyll development at temperatures below 24℃. A segregation test revealed that the sy-2 gene is controlled by a single recessive gene. To identify the sy-2 gene, we performed a map-based cloning approach using a total 600 individual F2 plants derived from crossing sy-2 and the wild type C. chinense ‘No.3341’. Fine-mapping of the locus allowed us to position sy-2 to an approximately 170-kb region flanked by markers IN2-1-1 and SNP-3-7 on chromosome 1. Among the approximately 36 hypothetical genes in this region several candidate genes including: HSP90-like ATPase family proteins, lipid-transfer proteins, calmodulin-domain protein kinases, and zinc finger proteins (ZFPs) were identified. RT-PCR and sequencing of the hypothetical genes are under way to identify sy-2.

Aiming at the problem of harmonic energy aggregation under the traditional space vector pulse width modulation (SVPWM) technique, a periodic pulse width modulation technique with a variable switching frequency band is proposed in the present study. PWM harmonic dispersion and suppression are achieved by periodizing the carrier frequency of two typical function signals. Then, the analytical model of periodic spread spectrum PWM technology is built to realize the dynamic adjustment of the random switching band. Based on the modulation theory, we analyze the inner mechanism of spread-spectrum modulation from the frequency domain perspective, revealing the relationship between bandwidth and PWM harmonic suppression eff ect. The harmonic suppression eff ects under diff erent kinds of modulation functions and diff erent spreading widths are compared by simulation and experiment, and the simulation and experimental results verify the eff ectiveness of the technique. It provides a reference for studying harmonic suppression of power converters by period spread spectrum PWM technology.
A miR-155–Peli1–c-Rel pathway controls the generation and function of T follicular helper cells
Liu, Wen-Hsien,Kang, Seung Goo,Huang, Zhe,Wu, Cheng-Jang,Jin, Hyun Yong,Maine, Christian J.,Liu, Yi,Shepherd, Jovan,Sabouri-Ghomi, Mohsen,Gonzalez-Martin, Alicia,Xu, Shunbin,Hoffmann, Alexander,Zheng, The Rockefeller University Press 2016 The Journal of experimental medicine Vol.213 No.9
<P>MicroRNA (miRNA) deficiency impairs the generation of T follicular helper (Tfh) cells, but the contribution of individual miRNAs to this phenotype remains poorly understood. In this study, we performed deep sequencing analysis of miRNAs expressed in Tfh cells and identified a five-miRNA signature. Analyses of mutant mice deficient of these miRNAs revealed that miR-22 and miR-183/96/182 are dispensable, but miR-155 is essential for the generation and function of Tfh cells. miR-155 deficiency led to decreased proliferation specifically at the late stage of Tfh cell differentiation and reduced CD40 ligand (CD40L) expression on antigen-specific CD4<SUP>+</SUP> T cells. Mechanistically, miR-155 repressed the expression of Peli1, a ubiquitin ligase that promotes the degradation of the NF-κB family transcription factor c-Rel, which controls cellular proliferation and CD40L expression. Therefore, our study identifies a novel miR-155–Peli1–c-Rel pathway that specifically regulates Tfh cell generation and function.</P>
