An agile bicycle-like robot for complex steel structure inspection
No full textThis paper presents a simple but compact design of a bicycle-like robot for inspecting complex-shaped ferromagnetic structures. The design concept for versatile locomotion relies on two independently steered magnetic wheels formed in a bicycle-like configuration, allowing the robot to possess multi-directional mobility. The key feature of a reciprocating mechanism enables the robot to change its shape when passing obstacles. A dynamic joint of the robot configuration makes it naturally adapt to uneven and complex surfaces of steel structures. We demonstrate the usability and practical deployment of the robot for steel thickness measurement using an ultrasonic sensor
デングウイルス非構造タンパク質NS4Bの一残基変異はヒト細胞においてインターフェロンの応答を抑制しウイルス増殖および適合性を増強する
No full textDengue virus (DENV) replication between mosquito and human hosts is hypothesized to be associated with viral determinants that interact in a differential manner between hosts. However, the understanding of inter-host viral determinants that drive DENV replication and growth between hosts is limited. Through the use of clinical isolates, we identified an amino acid variation of Ala, Met and Val at position 116 of DENV-1 NS4B. While the proportion of virus with the NS4B-116V variant remained constantly high in serial passages in a mosquito cell line, populations of the NS4B-116M and NS4B-116A variants became dominant after serial passages in mammalian cell lines. Using recombinant DENV-1 viruses, the Val to Ala or Met alteration at position NS4B-116 (rDENV-1-NS4B-116A and rDENV-1-NS4B-116M) resulted in enhanced virus growth in human cells in comparison to the clone with Val at NS4B-116 (rDENV-1-NS4B-116V). However, the reverse phenomenon was observed in a mosquito cell line. Additionally, in a human cell line, differential levels of IFN-α/β and IFN-stimulated gene expressions (IFIT3, IFI44L, OAS1) suggested that the enhanced viral growth was dependent on the ability of the NS4B protein to hamper host IFN response during the early phase of infection. Overall, we identified a novel and critical viral determinant at the pTMD3 of NS4B region that displayed differential effects on DENV replication and fitness in human and mosquito cell lines. Taken together, the results suggest the importance of the NS4B protein in virus replication and adaptation between hosts.長崎大学学位論文 学位記番号:博(医歯薬)甲第1098号 学位授与年月日:平成30年9月20日Author: Thuy Thu Bui, Meng Ling Moi, Takeshi Nabeshima, Taichiro Takemura, Trang Thu Nguyen, Linh Ngoc Nguyen, Hang Thi Thu Pham, Thi Thu Thuy Nguyen, Dao Huy Manh, Shyam Prakash Dumre, Shusaku Mizukami, Kenji Hirayama, Shigeru Tajima, Mai Thi Quynh Le, Kiyoshi Aoyagi, Futoshi Hasebe and Kouichi MoritaCitation: Journal of General Virology, 99(8), pp.1044-1057; 201

A new development of ANFIS-Based Henry gas solubility optimization technique for prediction of soil shear strength
No full textThis research provides an innovative combination of an adaptive neuro-fuzzy inference system (ANFIS) model for solving a nonlinear and complex problem related to soil shear strength prediction. The new hybrid model is optimized by an optimization technique i.e., Henry gas solubility optimization (HGSO), called as HGSO-ANFIS. In predicting soil shear strength, the results of liquid limit, specific gravity, clay content, moisture content, void ratio, and plastic limit were considered and used as the model predictors. The HGSO-ANFIS model is implemented based on Henry's law and can be used in engineering issues. The HGSO algorithm is developed based on the huddling behavior of gas to find the main answers and to avoid being trapped in the local minima. The search space in this model can be presented with a better performance than the base model. The performance of the new hybrid HGSO-ANFIS model was tested with real data to compare the other ANFIS-based models. The performance of the best HGSO-ANFIS model for the testing data was 0.954 and 0.1891 for coefficient of determination (R ) and root mean square error (RMSE), respectively. The model results showed that the new hybrid HGSO-ANFIS model can get higher level of accuracy compared to the other ANFIS-based models and it can be applied for various prediction and optimization problems.
Genetic diversity of local rice varieties (Oryza sativa L.) in Vietnam’s Mekong Delta based on SSR markers and morphological characteristics
No full textBased on target traits, use of the genetic diversity of rice is beneficial for crop improvement. In this study, 41 rice varieties local to Vietnam’s Mekong Delta were evaluated on the basis of 11 quantitative morphological traits, along with the assessment of genetic diversity according to 50 SSR markers. The actual yield had a significance level of 0.05, while plant height and panicles per square meter had a high significance level of 0.001. Cluster analysis based on 11 quantitative traits also revealed that two were the optimal number of clusters used in this study. The highest polymorphic information content (PIC) value obtained was for RM286 (0.49), with a range of 0.00 to 0.49 and an average PIC of 0.14. Both structure and phylogenetic tree analyses as inferred from 50 SSR markers by the unweighted pair‐group method with arithmetic mean (UPGMA) also indicated that the 41 local rice varieties could be divided into two major groups. This study provides a useful information for Mot bui do cao CM, and Mot bui five varieties for improvements in the yield and intermediate amylose content of local rice‐breeding programs in future, especially for the Mekong Delta region
