Transcomplementation, but not Physical Association of the CC-NB-ARC and LRR Domains of Tomato R Protein Mi-1.2 is Altered by Mutations in the ARC2 Subdomain

引用

Molecular Plant 2008年第3期1卷 401-410页

Race-specific disease resistance in plants is mediated by Resistance （R） proteins that recognize pathogen at- tack and initiate defence responses. Most R proteins contain a central NB-ARC domain and a C-terminal leucine-rich repeat （LRR） domain. We analyzed the intramolecular interaction of the LRR domain of tomato R protein Mi-1.2 with its N- terminus. We expressed the CC-NB-ARC and LRR parts in trans and analyzed functional transcomplementation and physical interactions. We show that these domains functionally transcomplement when expressed in trans. Known autoactivating LRR domain swaps were found to induce a hypersensitive response （HR） upon co-expression. Likewise, autoactivating mutants in the NB subdomain transcomplemented to induce HR. Point mutations in the ARC2 subdomain that induce strong autoactivation in the full-length Mi-1.2 protein, however, fail to induce HR in the transcomplementation assay, These data indicate distinct functions for the NB-ARC subdomains in induction of HR signalling. Furthermore, dissociation of the LRR is not required to release its negative regulation, as in all combinations of CC-NB-ARC and LRR domains tested, a physical interaction was observed.

Valence Band Splitting in Wurtzite InP Nanowires Observed by Photoluminescence and Photoluminescence Excitation Spectroscopy

引用

Nano Research 2011年第2期4卷 159-163页

作者： gerben L. Tuin Magnus T. Borgstrom Johanna Tragardh Martin Ek L. Reine Wallenberg Lars Samuelson Mats-Erik Pistol Solid State Physics/Nanometer Structure Consortium Box 118 Lund University S-221 00 Lund Sweden Polymer ＆ Materials Chemistry/nCHREM Lund University S-22100 Lurid Sweden

We have investigated individual bulk-like wires of wurtzite InP using photoluminescence, photoluminescence excitation spectroscopy and transmission electron microscopy. Using two different methods we find that the top of the valence band is split, as expected theoretically. This splitting of the valence band is peculiar to wurtzite InP and does not occur in zinc blende InP. We find the energy difference between the two bands to be 40 meV.

Assessing Social Vulnerability to Flood Hazards in the Dutch Province of Zeeland

International Journal of Disaster Risk Science 2019年第2期10卷 233-243页

The 2007 European Union Floods Directive encouraged member nations to pursue a more integrated view of flood risks and management strategies, taking into account social vulnerabilities of residents. To date, most flood-risk analyses conducted by the Dutch government have focused on physical risk. This study utilizes fine-scale data to construct a social vulnerability index for 147 districts of the Dutch province of Zeeland, located in the Southwestern Delta and the scene of widespread devastation following the 1953 North Sea Flood. Factor analysis of 25 indicators of social vulnerability selected from related research in Europe and the United States results in seven factors explaining roughly 66% of the total variance. These factors of social vulnerability in Zeeland are urban density,low-income households, recent population change, female gender, train access, and self-employed and service-sector employment. The index was constructed using the toploading variable in each of these factors, with weights determined by the variance explained by each *** range from a low of 0.20 in Schore, municipality of Kapelle, to the highest score of 0.64 in Oudelandse Hoeve of Terneuzen. The most vulnerable districts are located in South Zeeland, with eight of the 10 found in *** majority of less vulnerable districts are located in Zeeland’s central region.

引言航空公司深知其枢纽轮辐式航线网络(hub-and-spoke system)的宝贵价值。旅客看重大型航线网络所能提供的中转联程服务,商务旅客尤其青睐大型枢纽机场之间的频繁班次。诚然,这同时也带来一些问题,如枢纽机场过分拥挤,旅客经常滞留等候,等等。而旅客们认为,这些麻烦和不便是他们旅行过程中必然要经历的,他们可以容忍。从某种意义上来说,航空公司的核心产品是航线网络,而不仅仅是交通运输。

概述传统型航空公司通过枢纽-轮辐式航线网络运输乘客,并向对时间敏感的商务旅客收取较高价格,从而在风平浪静的90年代使整个行业获得了合理的利润。但这些战略现在受到了来自低成本竞争对手、越来越普及的网上订票方式和行业本身长期以来的运力过剩的冲击,其结果就是:虽然需求旺盏,但许多航空公司却入不敷出。航空公司正在寻求新对策以应对新的竞争环境,这方面有三个策略尤其值得我们关注:挤干运营中的浪费;重新设计票价结构以及压缩运力。这些步骤意味着与过去成功的战略的彻底决裂,而考虑到本行业面临的新经济现状,这种决裂是有益的。
