Optogenetic control of transgene expression in Marchantia polymorpha
Applications in Plant Sciences, EarlyView.Abstract Premise The model liverwort Marchantia polymorpha is an emerging testbed species for plant metabolic engineering but lacks well‐characterized inducible promoters, which are necessary to minimize biochemical and physiological disruption when over‐accumulating target products.

PLANTS, PEOPLE, PLANET, EarlyView.With global weather patterns becoming more extreme and unpredictable, sourcing reliable irrigation water is vital for improving food security and conserving drinking water in drought‐prone areas. Emerging desalination technologies, which are still in the development phase, could potentially provide large quantities of slightly saline water for ...

Prescribed burning effectively maintains threatened species in semi‐natural grasslands on lava flows
PLANTS, PEOPLE, PLANET, EarlyView.Prescribed burning shows promise for managing certain grassland types, but relying solely on it often reduces plant diversity, including threatened species. In Japanese dry grasslands established on volcanic ejecta, we explored conditions under which burning maintains high diversity.

The Analysis of Impact on Per Capita Real GDP of Provinces in Western Region by Western Region Development Program [PDF]
, 2016 自改革开放以来，我国经济发展取得了巨大成就，但同时地区间经济发展水平的差距也越来越大，为了促进我国区域经济协调发展，缩小东西部地区发展差距，2000年国家正式实施了“西部大开发”战略。在政策实施15年积累了足够多数据的基础上，本文首先分析了“西部大开发”对西部省份人均实际GDP增长率的影响，在此基础上分析了“西部大开发”对我国经济收敛性的影响，从这相互联系的两方面对“西部大开发”的政策效果进行了评价，结论是“西部大开发”基本实现了其战略目标。 在政策绩效评价广泛应用的“反事实”方法中 ...

PLANTS, PEOPLE, PLANET, EarlyView.As climate change accelerates, breeding resilient crops is urgent. The date palm (Phoenix dactylifera L.), a crucial 18 billion USD fruit crop, underpins North African and West Asian oasis agroecosystems. This study investigates the genetics and morphology of its closest wild relative, the endemic and endangered Cape Verde date palm (Phoenix atlantica ...

Jianzhu Gangjiegou Jinzhan, 2003 著名的英国Cardington大尺度结构抗火试验掀起了一股对火灾中钠结构工作性能研究的热潮。特别是最近的研究针对整体的结构系统,而不是静定的独立的构件;集中研究大挠度情况,而不是小挠度情况。本文给出了这两个方面的先进研究的定性描述。这些描述可用来评估当前试验研究得出的钢结构抗火性能,以及未来试验研究的领域。对这两个方面的透彻理解是很重要的,它能提供对复杂的钢结构抗火性能的深入的本质理解。试验数据也是必需的,它可以验证不同的数值预测,这种数值预测正广泛地提供数据 ...

Jianzhu Gangjiegou Jinzhan, 2023 利用ABAQUS软件对14个T形PEC柱进行低周反复加载计算，分析不同参数对T形PEC柱抗震性能的影响规律。结果表明：T形PEC柱的滞回曲线呈饱满的平行四边形，且刚度退化稳定，耗能能力和延性良好；提高混凝土强度等级虽然可增大柱的初始刚度，但混凝土强度等级过高则会导致柱的延性降低，刚度退化加剧，抗震性能降低；在T形PEC柱内设置横向拉杆，且将x方向和z方向的横向拉杆相互焊接，有利于对混凝土形成套箍作用从而提高柱的抗震性能，但拉杆间距不宜大于150mm ...
