Study on aerodynamic coefficients and responses of the integrated catwalk of Halogaland Bridge

Wan, Jia-wei,Wang, Qi,Liao, Hai-li,Li, Ming-shui Techno-Press 2017 Wind and Structures, An International Journal (WAS Vol.25 No.3

Wind tunnel tests and numerical aerodynamic analyses were conducted for an integrated catwalk structure under strong winds. From the wind tunnel tests, it is found that the aerodynamic coefficients were different from those of the typical type. The drag coefficient was larger than typical and was sensitive to number of vertical meshes installed rather than the solidity ratio. Comparing with typical catwalk, the integrated one showed larger deformation under strong wind, and the large torsional deformation are mainly caused by drag force. It did not show aerodynamic divergence even the torsional deformation reaching $20^{\circ}$. The reason could be that the stiffness is smaller and thus the catwalk is able to deform to the shape compactable with higher loading. Considering safety for construction, storm rope system is introduced to the catwalk to reduce the deformation to acceptable level.

1990년대부터 이란 영화는 여러 국제영화제를 통해 소개되면서 세계 영화계의 주목을 받고 있다. 엄격한 규율을 따르는 이슬람 국가인 이란은 영화의 심의제도에 있어서도 엄격한 규제가 있지만 그러한 환경 아래에서 제작된 이란의 영화들은 오히려 탁월한 미학적 완성도를 보여주고 있다. 이란 영화는 이탈리아 네오리얼리즘의 영향과 이란 본토의 정치사회적 특징이 결합된 뉴웨이브 운동을 통해 이란만의 리얼리즘 영화를 정착해나갔고 뉴웨이브를 이끌었던 작가들의 작품에는 모두 당시 이란 영화만의 리얼리즘과 시적(詩的)인 특징이 서로 결합되어 있다는 공통적인 특징을 보여준다. 이란의 신예감독 아쉬가르 파라디는 그의 영화의 주제 면에서나 표현 형식면에서 모두 이탈리아 네오리얼리즘과 이란의 시적 리얼리즘의 어법을 계승하여 리얼리즘적 전통 안에 머무르면서도 동시에 내러티브와 연출양식에 있어 새로운 극적 요소들을 차용하여 그만의 독자적인 리얼리즘적 스타일을 만들어내고 있다. 본 연구는 아쉬가르 파라디 감독의 영화 <어바웃 엘리>를 분석대상으로 삼아 본 영화의 내러티브 분석과 연출적 특성을 정리해내며 아쉬가르 파라디 영화의 리얼리즘적 특성, 즉 리얼리즘의 계승과 전복을 드러내고자 한다. Since the 1990s, Iranian films have entered the international film stage in a unique way and have become the focus of international film industry. As an Islamic country which is strictly abides by the rules and regulations, Iran has a strict film censorship within the harsh domestic political environment. However, Iranian film makers overcame the obstacles of domestic censorship, and made films in various styles that have profound significance, which in result brought Iranian films into the international arena. At the same time, under the influence of the two new wave movements and Italian neo-realism, Iranian films have gradually formed an Iranian style of realism by combining the characteristics of Iranian localization. Looking at the leaders of the new wave, most of their works reflect the commonality of Iranian cinema that combines realism and poetry. As a new-generation of Iranian director, Asghar Farhadi has inherited some of the characteristics of Italian neo-realism and Iranian poetic realism, both in terms of film theme and performance. Meanwhile, there are dramatic elements in his works that reflect his own style. This study analyzed the film “About Elly” which directed by Asghar Farhadi, through the combination of the inheritance and subversion of realism in his films, to study realism appeared in his works.

( Xin Qi Jia ) , ( Wan Fu Xi ) 한국윤리학회 2014 倫理硏究 Vol.95 No.1

Social philosophy is the study of people`s conception of basic social objectives. It can be divided into two categories based on two different basic objectives: harmony and strength. Harmony-oriented social philosophy and strength-oriented social philosophy are dominant in traditional society and modern society respectively. From the perspective of social philosophy, we can understand better the differences between traditional ethics and modern ethics.

SMAD4 Suppresses AURKA-Induced Metastatic Phenotypes via Degradation of AURKA in a TGFβ-Independent Manner

Jia, Lina,Lee, Hun Seok,Wu, Chun Fu,Kundu, Juthika,Park, Sang Gyu,Kim, Ryong Nam,Wang, Li-Hui,Erkin, Ö,zgü,r Cem,Choi, Jong-Sun,Chae, Seoung Wan,Yang, Ho Bin,Choi, Yoon-La,Shin, Young Kee American Association for Cancer Research 2014 Molecular Cancer Research Vol.12 No.12

<P>SMAD4 has been suggested to inhibit the activity of the WNT/β-catenin signaling pathway in cancer. However, the mechanism by which SMAD4 antagonizes WNT/β-catenin signaling in cancer remains largely unknown. Aurora A kinase (AURKA), which is frequently overexpressed in cancer, increases the transcriptional activity of β-catenin/T-cell factor (TCF) complex by stabilizing β-catenin through the inhibition of GSK-3β. Here, SMAD4 modulated AURKA in a TGFβ-independent manner. Overexpression of SMAD4 significantly suppressed AURKA function, including colony formation, migration, and invasion of cell lines. In addition, SMAD4 bound to AURKA induced degradation of AURKA by the proteasome. A luciferase activity assay revealed that the transcriptional activity of the β-catenin/TCF complex was elevated by AURKA, but decreased by SMAD4 overexpression. Moreover, target gene analysis showed that SMAD4 abrogated the AURKA-mediated increase of β-catenin target genes. However, this inhibitory effect of SMAD4 was abolished by overexpression of AURKA or silencing of AURKA in SMAD4-overexpressed cells. Meanwhile, the SMAD4-mediated repression of AURKA and β-catenin was independent of TGFβ signaling because blockage of TGFβR1 or restoration of TGFβ signaling did not prevent suppression of AURKA and β-catenin signaling by SMAD4. These results indicate that the tumor-suppressive function of SMAD4 is mediated by downregulation of β-catenin transcriptional activity via AURKA degradation in a TGFβ-independent manner.</P><P><B>Implications:</B> SMAD4 interacts with AURKA and antagonizes its tumor-promoting potential, thus demonstrating a novel mechanism of tumor suppression. <I>Mol Cancer Res; 12(12); 1779–95. ©2014 AACR</I>.</P>

Weighted sparsity-based denoising for extracting incipient fault in rolling bearing

Wan Zhang,Minping Jia,Xiaoan Yan,Lin Zhu 대한기계학회 2017 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.31 No.10

Given that the incipient fault is too weak for extraction, a novel approach that is based on sparse optimization is proposed for incipient fault diagnosis. The proposed optimization method consists of three steps: First, autocorrelation analysis is utilized to filter broadband random noise. Then, the weighted sparsity-based denoising method is proposed to extract periodic impulses. The prior knowledge that periodic impulses are sparse is used to constitute a penalty term; thus a novel weighted sparse optimization model is established. The majorization-minimization method is used to solve the optimization model. The high-pass filter in quadratic fidelity term is constructed by a Butterworth filter based on banded matrices, thus effectively improving computational efficiency. Lastly, the interval of periodic impulses, which corresponds to the fault frequency of rolling bearing, is obtained. Moreover, simulation and experimental results show that the proposed approach can successfully extract fault features from the signals of low signal to noise ratio.

Gloeostereum incarnatum has edible and medicinal value and was first cultivated and domesticated in China. We sequenced the G. incarnatum monokaryotic strain GiC-126 on an Illumina HiSeq X Ten system and obtained a 34.52-Mb genome assembly sequence that encoded 16,895 predicted genes. We combined the GiC-126 genome with the published genome of G. incarnatum strain CCMJ2665 to construct a genetic linkage map (GiC-126 genome) that had 10 linkage groups (LGs), and the 15 assembly sequences of CCMJ2665 were integrated into 8 LGs. We identified 1912 simple sequence repeat (SSR) loci and detected 700 genes containing 768 SSRs in the genome; 65 and 100 of them were annotated with gene ontology (GO) terms and KEGG pathways, respectively. Carbohydrate-active enzymes (CAZymes) were identified in 20 fungal genomes and annotated; among them, 144 CAZymes were annotated in the GiC-126 genome. The A mating-type locus (MAT-A) of G. incarnatum was located on scaffold885 at 38.9 cM of LG1 and was flanked by two homeodomain (HD1) genes, mip and beta-fg. Fourteen segregation distortion markers were detected in the genetic linkage map, all of which were skewed toward the parent GiC-126. They formed three segregation distortion regions (SDR1-SDR3), and 22 predictive genes were found in scaffold1920 where three segregation distortion markers were located in SDR1. In this study, we corrected and updated the genomic information of G. incarnatum. Our results will provide a theoretical basis for fine gene mapping, functional gene cloning, and genetic breeding the follow-up of G. incarnatum.

Background: In intensive care units, mechanical ventilation is an important therapy to help patients with dysp- nea. However, long-term ventilator dependence would consume huge medical resources and increase the risk of morbidity and mortality. The aim of the study was to examine the efficacy of the acupuncture combined with western medical care on ventilator parameters in ventilator-dependent patients. Methods: In this clinical trial, 80 ventilator-dependent patients aged 20 to 80 years old were randomly assigned to acupuncture group and control group in the respiratory care center (RCC) of Changhua Christian Hospital. Besides regular medical care and therapy, participants in the acupuncture group received acupuncture therapy at the same 17 acu-points for 20 minutes once a day, a total of 12 sessions. The ventilator parameters were recorded to evaluate the respiratory efficiency for all participants. The primary outcome was rapid shallow breathing index (RSBI), and secondary outcomes were respiratory rate (RR), tidal volume (TV) and ventilation per minute (MV). Results: Though there was no significant difference in the parameter between the acupuncture group and the control group, we found the trend of decreasing RSBI in the acupuncture group. In subgroup analyses, the mean of RSBI significantly decreased 16.02 (with the SD in 60.84) in acupuncture group, while it increased 17.84 (with the SD in 39.38) in control group (p = 0.036) after 12 sessions. Conclusion: Acupuncture treatment can improve breathing ability of patients with respirator dependence in respiratory care center.

A putative plastidial adenine nucleotide transporter, BRITTLE1-3, plays an essential role in regulating chloroplast development in rice (Oryza sativa L.)

Jia Lyu,Yihua Wang,Linglong Liu,Chunming Wang,Yulong Ren,Cheng Peng,Feng Liu,Yunlong Wang,Mei Niu,Di Wang,Ming Zheng,Kunneng Zhou,Shaolu Zhao,Fuqing Wu,Haiyang Wang,Jianmin Wan 한국식물학회 2017 Journal of Plant Biology Vol.60 No.5

Differentiation from proplastids into chloroplasts isa light- and energy-dependent process. How this process isregulated is still poorly understood at the molecular level. We herein report a new putative plastidial adenine nucleotidetransporter, BRITTLE1-3 (referred to as OsBT1-3), encoded bythe rice (Oryza sativa) White Stripe Leaf 2 (WSL2) gene. Loss of OsBT1-3 function results in defective chloroplastbiogenesis, severely reduced photosynthetic efficiency, andfinally a white stripe leaf phenotype in the first four leaves. The expression levels of genes related to chlorophyllbiosynthesis and photosynthesis are drastically reduced,accompanied with over accumulation of reactive oxygenspecies (ROS) in the wsl2 mutant. OsBT1-3 is targeted tothe chloroplasts and it expresses in almost all tissues inplants, especially in young leaves. OsBT1-3 consists of 419amino acids and exhibits features of all mitochondrialcarrier proteins, including a typical transmembrane-spanningdomain and a highly conserved sequence motif designatedas the ‘mitochondrial energy transfer signatures’. Phylogeneticanalysis shows that OsBT1-3 is a putative plastidialadenine nucleotide transporter and is most closely relatedto ZmBT1-2. Together, these observations suggest that thenew putative adenine nucleotide transporter, OsBT1-3,plays an essential role in regulating chloroplast biogenesisand maintenance of ROS homeostasis during rice seedlingde-etiolation.
