Design and analysis of Salisbury screens and Jaumann absorbers for solar radiation absorption

Xing FANG, C. Y. ZHAO, Hua BAO

《能源前沿（英文）》 2018年 第12卷 第1期   页码 158-168 doi: 10.1007/s11708-018-0542-6

摘要： Two types of resonance absorbers, i.e., Salisbury screens and Jaumann absorbers are systematically investigated in solar radiation absorption. Salisbury screen is a metal-dielectric-metal structure which overcomes the drawback of bulky thickness for solar spectrum. Such structures have a good spectral selective absorption property, which is also insensitive to incident angles and polarizations. To further broaden absorption bandwidth, more metal and dielectric films are taken in the structure to form Jaumann absorbers. To design optimized structural parameters, the admittance matching equations have been derived in this paper to give good initial structures, which are valuable for the following optimization. Moreover, the analysis of admittance loci has been conducted to directly show the effect of each layer on the spectral absorptivity, and then the effect of thin films is well understood. Since the fabrication of these layered absorbers is much easier than that of other nanostructured absorbers, Salisbury screen and Jaumann absorbers have a great potential in large-area applications.

Singularity loci of an orthogonal spherical two-degree-of-freedom parallel mechanism

Jialun YANG, Feng GAO,

《机械工程前沿（英文）》 2009年 第4卷 第4期   页码 379-385 doi: 10.1007/s11465-009-0075-0

摘要： Singularity analysis plays an important role in the design of robots, especially for parallel robots. In this paper, the direct and inverse kinematics of an orthogonal spherical two-degree-of-freedom parallel mechanism is proposed based on the modified Euler angles. All the singular poses of the mechanism are achieved through the direct kinematic analysis. Self-motions, which are different from the general spherical 5 parallel mechanisms, are also discussed. Singularity loci in the joint space and Cartesian space are plotted according to the Jacobin of the mechanism. Result shows that the singularity loci at the joint space are two circles and one line, whereas at the Cartesian space are a circle.

摘要： Wheat stripe rust caused by f. sp. is one of the most devastating diseases of wheat worldwide and resistant cultivars are vital for its management. Therefore, investigating the heterozygosity of the pathogen is important because of rapid virulence changes in isolates heterozygous for avirulence/virulence. An isolate of f. sp. was selfed on to determine the heterozygosity for avirulence/virulence loci. One hundred and twenty progeny isolates obtained from this selfing were phenotyped using 25 lines of wheat containing genes and genotyped with 96 simple sequencing repeat markers, with 51 pathotypes and 55 multi-locus genotypes being identified. All of these were avirulent on lines with , , , and and virulent on lines with , and , indicating that the parental isolate was homozygously avirulent or homozygously virulent for these loci. Segregation was found for wheat lines with , , , , , , , , , , , , , , , and . The 17 cultivars to which the was identified as heterozygous with respect to virulence/avirulence should not be given priority in breeding programs to obtain new resistant cultivars.

摘要： Intramuscular fat (IMF) is a major meat-quality trait in pigs. The content of IMF is directly associated with the taste and flavor of pork. As a complex trait, there could be multiple genes affecting IMF content in pork. Genome-wide association study is a powerful tool to detect genomic regions associated with phenotypic variations. The objectives of the present study were to identify or refine the positions of genomic regions affecting IMF, and to characterize candidate genes and pathways that may influence this trait. Of note, we identified a significant region in longissium dorsi muscle in a Duroc pig population for IMF content with PorcineSNP60 v2 BeadChip. This region spans 1.24 Mb on chromosome 8 and had been identified as a quantitative trait locus for IMF in Pietrain, Large White, Landrace, and Leicoma pigs. In this region, eight SNPs were significantly associated with IMF content. Three genes proximal to these significant SNPs were considered candidate genes, including , and . Our results confirm several previous findings and highlight several genes that may contribute to IMF variation in Duroc pigs.

Genetic study and molecular breeding for high phosphorus use efficiency in maize

《农业科学与工程前沿（英文）》 2019年 第6卷 第4期   页码 366-379 doi: 10.15302/J-FASE-2019278

摘要：

Phosphorus is the second most important macronutrient after nitrogen and it has many vital functions in the life of plants. Most soils have a low available P content, which has become a key limiting factor for increasing crop production. Also, low P use efficiency (PUE) of crops in conjunction with excessive application of P fertilizers has resulted in serious environmental problems. Thus, dissecting the genetic architecture of crop PUE, mining related quantitative trait loci (QTL) and using molecular breeding methods to improve high PUE germplasm are of great significance and serve as an efficient approach for the development of sustainable agriculture. In this review, molecular and phenotypic characteristics of maize inbred lines with high PUE, related QTL and genes as well as low-P responses are summarized. Based on this, a breeding strategy applying genomic selection as the core, and integrating the existing genetic information and molecular breeding techniques is proposed for breeding high PUE maize inbred lines and hybrids.

Aphanomyces euteiches ——加拿大豌豆生产的严重威胁 Review

摘要：

豌豆（Pisum sativum var. arvense L.）是世界上重要的豆科作物。豌豆籽粒蛋白质含量很高，并能提高土壤中有效氮的含量。由一种土传卵菌根腐丝囊霉（Aphanomyces euteiches Drechs.）引起的Aphanomyces 根腐病（ARR），在包括加拿大在内的许多地区对豌豆生产构成严重威胁，在潮湿的土壤条件下引起严重的根损伤、萎蔫，造成大幅度减产。在有利于病害发生的条件下，由于病原体卵孢子的寿命长，在豌豆任何生长阶段都可以侵染豌豆植株，传统病害防控措施（如作物轮作和拌种处理）不能完全防治病害的危害。培育部分抗病或耐病豌豆品种可能是分析豌豆中根腐丝囊霉变异性和生理转化性、提高病害防治效果的有效途径。因此，检测抗病数量性状基因座（QTL）对豌豆育种计划至关重要。本文对根腐丝囊霉的致病特点、ARR 防控措施以及部分与抗性相关的QTL 进行了综述。
