A New Solution for Stochastic Optimal Power Flow

Jinxia Gong,Da Xie,Chuanwen Jiang,Yanchi Zhang 대한전기학회 2014 Journal of Electrical Engineering & Technology Vol.9 No.1

A stochastic optimal power flow (S-OPF) model considering uncertainties of load and wind power is developed based on chance constrained programming (CCP). The difficulties in solving the model are the nonlinearity and probabilistic constraints. In this paper, a limit relaxation approach and an iterative learning control (ILC) method are implemented to solve the S-OPF model indirectly. The limit relaxation approach narrows the solution space by introducing regulatory factors, according to the relationship between the constraint equations and the optimization variables. The regulatory factors are designed by ILC method to ensure the optimality of final solution under a predefined confidence level. The optimization algorithm for S-OPF is completed based on the combination of limit relaxation and ILC and tested on the IEEE 14-bus system.

Effect of Ammonium in Medium on Ansamitocin P-3 Production by Actinosynnema pretiosum

Jinxia Lin,Linquan Bai,Zixin Deng,Jian-Jiang Zhong 한국생물공학회 2010 Biotechnology and Bioprocess Engineering Vol.15 No.1

Ansamitocin P-3 (AP-3) is an antitumor agent produced by Actinosynnema pretiosum with a market demand for large and cheap supply, but its productivity is yet low. This work investigated the effects of ammonium in medium on the productivity, enzyme activities, and gene transcription for AP-3 biosynthesis. As observed, AP-3 production was depressed by medium ammonium, although the dry cell weight and the consumption of total sugar and isobutanol were not influenced obviously. From the onset of AP-3 accumulation, isobutyrate accumulation showed a different behavior in medium with or without ammonium. Isobutanol dehydrogenase activity was enhanced during production phase in medium with ammonium, but valine dehydrogenase activity was not substantially changed. qRT-PCR analysis revealed that transcriptional levels of structure genes asm14, asm24, asm43, and asm19 were down-regulated by medium ammonium. The transcription of regulatory gene asm2, asm29, and asm31 were slightly up-regulated while that of asm39 was down-regulated by ammonium. The results indicated that inhibition of AP-3 production by ammonium might be related to the AP-3 ester side chain supply and the repression of gene transcription responsible for 3-amino-5-hydroxybenzoic acid and methoxymalonyl-ACP biosynthesis. The information is useful for future AP-3 productivity enhancement.

Defense Strategy of Network Security based on Dynamic Classification

( Jinxia Wei ),( Ru Zhang ),( Jianyi Liu ),( Xinxin Niu ),( Yixian Yang ) 한국인터넷정보학회 2015 KSII Transactions on Internet and Information Syst Vol.9 No.12

In this paper, due to the network security defense is mainly static defense, a dynamic classification network security defense strategy model is proposed by analyzing the security situation of complex computer network. According to the network security impact parameters, eight security elements and classification standard are obtained. At the same time, the dynamic classification algorithm based on fuzzy theory is also presented. The experimental analysis results show that the proposed model and algorithm are feasible and effective. The model is a good way to solve a safety problem that the static defense cannot cope with tactics and lack of dynamic change.

Interleukin-22 Attenuates Acute Pancreatitis-Associated Intestinal Mucosa Injury in Mice via STAT3 Activation

( Jinxia Bai ),( Jinyun Bai ),( Meng Yang ) 대한소화기기능성질환·운동학회 2021 Gut and Liver Vol.15 No.5

Background/Aims: Interleukin-22 (IL-22) is an important cytokine maintaining homeostasis at barrier surfaces. In this study, the role of IL-22 in acute pancreatitis-associated intestinal injury was further explored. Methods: Severe acute pancreatitis (SAP) was induced by administration of L-arginine in Balb/c mice at different time gradients. Histopathological examinations were made in both the pancreas and small intestine. Furthermore, recombinant murine IL-22 (rIL-22) was administrated to L-arginine-induced SAP mice by intraperitoneal injection. The mRNA levels of IL-22R1, Reg-IIIβ, Reg-IIIγ, Bcl-2, and Bcl-xL were detected in the small intestine by real-time polymerase chain reaction, and protein levels of total and phosphorylated STAT3 were assessed via Western blot. Results: Compared with normal control group, 72 hours of L-arginine exposure induced the most characteristic histopathological changes of SAP, evidenced by pathological changes and serum amylase levels. Meanwhile, significant pancreatitis-associated intestinal mucosa injury was also observed. The gene expression levels of antimicrobial proteins Reg-IIIβ, Reg-IIIγ and anti-apoptosis proteins Bcl-2, Bcl-xL were downregulated in small intestine. Furthermore, Larginine- induced SAP was attenuated by rIL-22 treatment. Importantly, pancreatitis-associated intestinal mucosa injury was also ameliorated, reflected by improved pathological changes and significant increase in gene expression levels of Reg-IIIβ, Reg-IIIγ, Bcl-2 and Bcl-xL. Consistently, serum amylase levels and mortality were decreased in mice treated with rIL-22. Mechanistically, the upregulated expressions of these protective genes were achieved by activating STAT3. Conclusions: Exogenous rIL-22 attenuates L-arginine-induced acute pancreatitis and intestinal mucosa injury in mice, via activating STAT3 signaling pathway and enhancing the expression of antimicrobial peptides and antiapoptotic genes.

Study on Inheritance of Potato virus X Resistance in Capsicum annuum

Shi, Jinxia,Choi, Do-Il,Kim, Byung-Dong,Kang, Byoung-Cheorl The Korean Society of Plant Pathology 2008 Plant Pathology Journal Vol.24 No.4

Potato virus X (PVX) resistance in potato is one of the best-characterized resistance models, however little is known in pepper. To evaluate the resistance to PVX in Capsicum annuum, a total of eleven pepper accessions were used for resistance screening against two PVX strains, USA and UK3. None of them were resistant against strain UK3, whereas four resistant genotypes were found against strain USA, three of which were further characterized. Two unlinked dominant genes were identified for both genotypes Bukang and Perennial; resistance in the genotype CV3 seemed to be conferred by two complementary dominant genes. These results demonstrated that the resistance to PVX in C. annuum is different from that in potato. This is the first report on genetic analysis of PVX resistance in C. annuum.
