Legume NADPH Oxidases Have Crucial Roles at Different Stages of Nodulation

Plant NADPH oxidases, formerly known as respiratory burst oxidase homologues (RBOHs), are plasma membrane enzymes dedicated to reactive oxygen species (ROS) production. These oxidases are implicated in a wide variety of processes, ranging from tissue and organ growth and development to signaling pathways in response to abiotic and biotic stimuli. Research on the roles of RBOHs in the plant’s response to biotic stresses has mainly focused on plant-pathogen interactions; nonetheless, recent findings have shown that these oxidases are also involved in the legume-rhizobia symbiosis. The legume-rhizobia symbiosis leads to the formation of the root nodule, where rhizobia reduce atmospheric nitrogen to ammonia. A complex signaling and developmental pathway in the legume root hair and root facilitate rhizobial entrance and nodule organogenesis, respectively. Interestingly, several reports demonstrate that RBOH-mediated ROS production displays versatile roles at different stages of nodulation. The evidence collected to date indicates that ROS act as signaling molecules that regulate rhizobial invasion and also function in nodule senescence. This review summarizes discoveries that support the key and versatile roles of various RBOH members in the legume-rhizobia symbiosis.

Synthesis of C‐H‐O Symbiosis Networks

The concept of synthesizing carbon, hydrogen, and oxygen (C‐H‐O) SYmbiosis Networks (CHOSYNs) for the design of eco‐industrial parks is introduced. Within a CHOSYN, compounds containing C‐H‐O are exchanged, converted, separated, mixed, and allocated. The use of C‐H‐O as the basis for integration creates numerous opportunities for synergism because C, H, and O are the primary building blocks for many industrial compounds that can be exchanged and integrated. A particularly attractive feature of the CHOSYN framework is its ability to use atomic‐based targets to establish benchmarks for the design of macroscopic systems involving multiple processes. Several structural representations, benchmarking, and optimization formulations are developed to embed potential CHOSYN configurations of interest and to synthesize cost‐effective networks. A case study with several scenarios is solved to demonstrate the new concept and tools. © 2015 American Institute of Chemical Engineers AIChE J, 61: 1242–1262, 2015     

融合核密度估计和奇异值分解的多样化推荐算法

现今的推荐算法大多以提高推荐列表准确率为目标,而对推荐的多样性考虑较少,这样会导致推荐结果新颖性不强,在考虑多样性的时候又会降低准确率.本文提出了一种融合兴趣分布与奇异值分解的多样化推荐算法(KDE-SVD),首先使用核密度估计的方式估计用户兴趣分布,得出用户在兴趣分布上相似的邻居,并使用兴趣分布上相似的邻居的评分对当前用户未评分的物品进行预评分,然后将上一步得到的预评分填入用户-评分矩阵,进行SVD分解,此时获取推荐列表即包含了兴趣相似邻居预评分而来的物品,保证推荐列表的多样性,也有SVD分解而得的行为相似邻居的物品,保证推荐列表的准确率.在实验数据集上实验表明,该本文算法能保证准确率的的情况下充分提高推荐多样性.
