We construct a new class of subspace lattices L on an infinite-dimensional Hilbert space *** show that the bounded cohomology groups Hn(Alg L, B(K)) of the corresponding lattice algebras Alg L with coefficients in B(K) are trivial for all n ≥ 1, and every derivation φ from Alg L into Alg L is an inner derivation under some conditions. We also prove that every Lie derivation δ from Alg L into B(K) is standard.

Glucosinolates(GSLs) are a group of nitrogen-and sulfur-containing secondary metabolites, synthesized primarily in members of the Brassicaceae family, that play an important role in food flavor, plant antimicrobial activity, resistance to insect attack, stress tolerance, and human anti-cancer effects. As a sulfur-containing compound, glutathione has a strong connection with GSLs biosynthesis as a sulfur donor or redox system, and exists in reduced(glutathione;GSH) and oxidized(glutathione disulfide;GSSG) forms. However, the mechanism of GSH regulating GSLs biosynthesis remainds unclear. Hence, the exogenous therapy to pakchoi under normal growth condition and sulfur deficiency condition were conducted in this work to explore the relevant mechanism. The results showed that exogenous application of buthionine sulfoximine, an inhibitor of GSH synthesis, decreased the transcript levels of GSLs synthesis-related genes and transcription factors, as well as sulfur assimilation-related genes under the normal growth condition. Application of exogenous GSH inhibited the expression of GSLs synthesis-and sulfur assimilation-related genes under the normal condition, while the GSLs biosynthesis and the sulfur assimilation pathway were activated by exogenous application of GSH when the content of GSH in vivo of plants decreased owing to sulfur deficiency. Moreover,exogenous application of GSSG increased the transcript levels of GSLs synthesis-and sulfur assimilation-related genes under the normal growth condition and under sulfur deficiency. The present work provides new insights into the molecular mechanisms of GSLs biosynthesis underlying glutathione regulation.

为研究侧向冲击荷载作用下钢丝绳的动力响应,分别对单根钢丝绳和交叉钢丝绳网进行了抗冲击试验,并考虑了其表面状态及材质、直径和连接方式对钢丝绳抗冲击性影响。结合材料的拉伸试验,分析了钢丝绳的静力和动力性能。结果表明,不同的表面状态及材质只影响钢丝绳弹性阶段的变形能力,对钢丝绳承载能力影响不大。钢丝绳表面状态及材质仅对静力拉伸下的弹性模量有影响,对钢丝绳抗冲击性能的影响不大;针对单根钢丝绳冲击试验工况,相同冲击物质量冲击时,直径越小的钢丝绳中部应变值较大,直径越大的钢丝绳端部应变值较大;卡扣连接的钢丝绳经历了由松弛状态到绷紧状态再到受荷状态三个不同的阶段,螺栓连接的钢丝绳直接从绷紧状态开始到受荷状态,卡扣连接钢丝绳变形比螺栓连接的大,受强冲击荷载时容易失效,连接可靠度低。
