High molecular weight (HMW) glutenin subunits (GS) play a key role in the determination of end‐use quality of wheat and other cereal crops. In this study, we report the isolation and characterization of both promoter region and ORF of novel HMW‐GS allele 1St1.3 from a perennial Triticeae species,Elymus canadensis. The amino acid (AA) sequences of E. canadensis 1St1.3 were deduced as 434 aa. Its protein primary structure comprises a signal peptide with a conserved N‐terminal domain, a central repetitive domain and a C‐terminal domain. E. canadensis 1St 1.3 possesses several distinct characteristics which are different from those of wheat HMW‐GSs. The N‐terminal domains of E. canadensis 1St 1.3 resemble that of y‐type subunits, while their C‐terminal domains are more similar to x‐type subunits. The deletion of 85 bp fragment has been observed in promoter region of 1St 1.3, however which has not interrupted the expression of this gene. Our results indicate that 1St 1.3 is novel HMW‐GS variants which will be valuable for enhancing our understanding of structural differentiation and the evolutionary relationship among HMW‐GSs in Triticeae species.

30年代中國文壇的重要一翼 : 民族主義文藝運動社團與報刊考辨

錢振綱 中國語文硏究會 2001 中國語文論叢 Vol.21 No.-

민족주의 문예운동은 국민당의 은밀한 지지 하에 일어난 것으로, 1930년대 중국 문단의 일대 사건이라 할 수 있을 것이다.이러한 민족주의 문예운동 중에는 적지 않은 文藝社團과 문예잡지가 등장하였으므로 민족주의 문예운동에 대해 보다 깊이 있는 연구를 하기 위해서는 문예사단과 잡지에 대한 고찰이 먼저 이루어져야할 필요가 있다.민족주의 문예운동의 발전사는 대개 두 시기를 거쳤다고 생각해 볼 수 있는데, 본 고에서는 사단과 잡지에 대한 고찰을 하되, 그 진행과정을 전ㆍ후기로 나누어 살펴보았다.그리고 당시에는 또 다른 우익문예사단과 잡지가 잇었는데, 이것을 민족주의 문예파로 오인하는 경우가 있어, 그것에 대해서도 구분하여 설명하였다.

Comparative field tests on uplift behavior of straight-sided and belled shafts in loess under an arid environment

Qian, Zeng-zhen,Lu, Xian-long,Yang, Wen-zhi,Cui, Qiang Techno-Press 2016 Geomechanics & engineering Vol.11 No.1

This study elucidates the uplift behaviors of the straight-sided and belled shafts. The field uplift load tests were carried out on 18 straight-sided and 15 belled shafts at the three collapsible loess sites under an arid environment on the Loess Plateau in Northwest China. Both the site conditions and the load tests were documented comprehensively. In general, the uplift load-displacement curves of the straight-sided and belled shafts approximately exhibited an initial linear, a curvilinear transition, and a final linear region, but did not provide a well defined peak or asymptotic value of the load, and therefore their uplift resistances should be interpreted from the load test results using an appropriate criterion. Nine representative uplift resistance interpretation criteria were used to define the "interpreted failure load" for each of the load tests, and all of these interpreted uplift resistances were normalized by the failure threshold, $T_{L2}$, obtained using the $L_1-L_2$ method. These load test data were compared statistically and graphically. For the straight-sided and belled shafts, the normalized uplift load-displacement curves were respectively established by the plots that related the mean interpreted uplift resistance ratio against the mean displacement at the corresponding interpreted criteria, and the comparisons of the normalized load-displacement curves were made. Specific recommendations for the designs of uplift belled and straight-sided shafts in the loess were given, in terms of both capacity and displacement.

Behaviour of micropiles in collapsible loess under tension or compression load

Qian, Zeng-Zhen,Lu, Xian-Long,Yang, Wen-Zhi,Cui, Qiang Techno-Press 2014 Geomechanics & engineering Vol.7 No.5

This study examines the behaviour of single micropiles subjected to axial tension or compression load in collapsible loess under in-situ moisture content and saturated condition. Five tension loading tests and five compression loading tests on single micropiles were carried out at a typical loess site of the Loess Plateau in Northwest China. A series of laboratory tests, including grain size distribution, specific gravity, moisture content, Atterberg limits, density, granular components, shear strength, and collapse index, were carried out during the micropile loading tests to determine the values of soil parameters. The loess at the test site poses a severe collapse risk upon wetting. The tension or compression load-displacement curves of the micropiles in loess, under in-situ moisture content or saturated condition, can generally be simplified into three distinct regions: an initial linear, a curvilinear transition, and a final linear region, and the bearing capacity or failure load can be interpreted by the L1-L2 method as done in other studies. Micropiles in loess should be considered as frictional pile foundations though the tip resistances are about 10%-15% of the applied loads. Both the tension and compression capacities increase linearly with the ratio of the pile length to the shaft diameter, L/d. For micropiles in loess under in-situ moisture content, the interpreted failure loads or capacities under tension are 66%-87% of those under compression. However, the prewetting of the loess can lead to the reductions of 50% in the tensile bearing capacity and 70% in the compressive bearing capacity.

LFT Modeling and Robust Stability Analysis of Missiles with Uncertain Parameters

HOU Zhen-qian,LIANG Xiao-geng,WANG Wen-zheng,LI Rui 한국항공우주학회 2014 International Journal of Aeronautical and Space Sc Vol.15 No.2

The structured singular value (μ) analysis based method has many advantages for the robust stability analysis of missiles with uncertain parameters. Nevertheless, the present linear fractional transformation (LFT) modeling process, which is the basis of μ analysis, is complex, and not suitable for automatic implementation; on the other hand, μ analysis requires a large amount of computation, which is a burden for large-scale application. A constructive procedure, which is computationally more efficient, and which may lead to a lower order realization than existing algorithms, is proposed for LFT modeling. To reduce the calculation burden, an analysis method is developed, based on skew μ. On this basis, calculation of the supremum of μ over a fixed frequency range converts into a single skew μ value calculation. Two algorithms are given, to calculate the upper and lower bounds of skew μ, respectively. The validity of the proposed method is verified through robust stability analysis of a missile with real uncertain parameters.

Qian Guangjing,Song Xueyu,Sun Jiazhao,Zhang Shuping,Zhou Xiazhi,Zhang Guoqing,Zou Yunding,Fang Guofei,Zhang Zhen,Yan Ping,Bi Shoudong 한국곤충학회 2020 Entomological Research Vol.50 No.8

To improve the accuracy of forecasting the peak occurrence of Dendrolimus punctatus Walker, we here used the Bayes discriminant analysis to predict this peak occurrence for the first and second generation of Dendrolimus punctatus larvae based on these data from 1983 to 2016 in Qianshan County, Anhui Province. Our present results showed that this discriminant equation for the first generation was as follows: f (1) = 3.2588-6.2700x1 + 1.2870x2 + 0.7920x3 + 0.4152x4; f (2) = 14.5215- 8.5710x1 + 2.9790x2 + 2.0280x3 + 0.5031x4; f (3) = 3.5264; f (4) = 66.8312- 12.5216x1 + 5.1740x2 + 4.7162x3 + 0.6033x4. And that the prediction accuracy for the first generation was 97.22%. Whilst this discriminant equation for the second generation was as follows: f (1) = 3.536-1.192x5 + 1.338x6 + 0.638x70.025x8; f (2) = 7.317-1.337x5 + 4.240x6 + 1.010x70.295x8; f (3) = 16.488- 3.192x5 + 4.955x6 + 1.900x7–0.411x8; f (4) = 34.502- 4.184x5 + 7.484x6 + 2.583x7–0.443x8. The prediction accuracy for the second generation was 85.71%. Overall, our findings revealed that the Bayes discriminant analysis could screen out key factors to significantly improve the prediction accuracy of peak occurrence of Dendrolimus punctatus larvae.

Qian, Yi-Hua,Huang, Yi-Bin,Fu, Qiang,Zhong, Zhen-Sheng The Korean Institute of Electrical Engineers 2013 Journal of Electrical Engineering & Technology Vol.8 No.3

Under the condition of Baader aging, the chemical composition variation and the influence of transformer oil aging on electrical properties such as dielectric loss factor and physic-chemical properties such as interfacial tension were studied in the aging precess. Moreover, the correlation between hydrogenated transformer oil electrical and physic-chemical properties and its chemical composition variation were also investigated. The results show that these parameters of physic-chemical and electrical properties of hydrogenated transformer oil relate to each other and have closed correlation with chemical composition.
