Characteristics of odorous carbonyl compounds in the ambient air around a fishery industrial complex of Yeosu,Korea

In this study, the amounts of odorous carbonyl compounds （OCCs） including acetaldehyde （Acet-A）, propionaldehyde （Pron-A）, butylaldehyde （Buty-A）, iso-valeric aldehyde （Iso-Vale-A） and n-valeric aldehyde （N-Vale-A） emitted from a fishery industrial complex near the exhibition facilities of ＂Expo 2012 Yeosu Korea＂ were measured. Acet-A was found to be the most abundant OCC, and the total concentrations of the OCCs were the highest in the summer. However, due to vehicular exhaust and photochemical reactions, the concentrations of some of the OCCs presented their highest levels in the fall. A significant correlation between Acet-A and Buty-A was found at the major fishery facilities （r = 0.816, p = 1.87E-15, n = 60） and at the border areas （r = 0.809, p = 3.40E-12, n = 48） of this fishery industrial complex. The concentrations of OCCs at the border areas were not worse than those at the urban areas in other places, indicating that the concentrations of ambient OCCs at the border areas were not greatly influenced by manmade activities.

Perpendicular magnetic clusters with configurable domain structures via dipole-dipole interactions

Nano Research 2015年第11期8卷 3639-3650页

Magnetic single-domain islands based on in-plane anisotropy （usually, shape anisotropy） and their dipole-dipole interactions have been investigated extensively in recent years. This has been driven by potential applications in magnetic recording, spintronics, magneto-biology, etc. Here, we propose a concept of out- of-plane magnetic dusters with configurable domain structures （multi-flux states） via dipole-dipole interactions. Their flux stages can be switched through an external magnetic field. The concept has been successfully demonstrated by patterned [Co/Pd] islands. A [Co/Pd] multilayer exhibits a large perpendicular anisotropy, a strong physical separation, and uniform intrinsic properties after being patterned into individual islands by electron beam lithography. A three- island cluster with six stable flux states has been realized by optimizing island size, thickness, gap, anisotropy, saturation magnetization, etc. Using [Co/Pd] multilayers, we have optimized the island structure by tuning magnetic properties （saturation magnetization and perpendicular anisotropy） using Landau-Liftshitz- Gilbert （LLG） simulation/calculation. Potential applications have been proposed, including a flexi-programmable logic device with AND, OR, NAND, and NOR functionalities and a magnetic domino, which can propagate magnetic current as far as 1 μm down from the surface via vertical dipole-dipole interactions.

极化合成孔径雷达(SAR)图像的相干斑严重影响图像信息的有效提取,为此提出一种基于极化散射特性的相干斑抑制方法。该方法结合SAR图像的冗余信息及其散射特性的相似性,利用Wishart分布对SAR数据的相似性进行度量,然后依据相似性计算权重对协方差矩阵进行加权平均,实现对极化SAR图像的相干斑抑制。本文方法对协方差矩阵的各元素单独处理,因此在极化信息的保留方面尤具优势。通过真实SAR数据的实验表明,该方法与现有极化白化滤波(PWF)和极化lee滤波相比,具有更好的相干斑抑制能力和细节的保持能力。
