Barley HvBODYGUARD1 controls cuticular specialisations regulated by SHINE transcription factors
New Phytologist, Volume 251, Issue 3, Page 1188-1208, August 2026.Cuticle defects result from defective HvBDG1 alleles. Summary Land plants secrete a protective outer cuticular layer with diverse functions. Barley (Hordeum vulgare L.) develops two cuticular specialisations: the β‐diketone rich wax bloom on vegetative tissues and an adherent grain surface which sticks to the hulls, leading to barley's distinctive ...

Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19
Policy Studies Journal, Volume 54, Issue 3, August 2026.Abstract The COVID‐19 pandemic sparked unprecedented experimentation in the German social assistance system, leading to changes previously considered impracticable by policymakers. This included a sanctions moratorium, easier access to benefits, and temporary cash transfers, all of which were advocated by welfare associations—key organized interests ...

Jianzhu Gangjiegou Jinzhan, 2017 建立了双钢板-混凝土组合剪力墙的精细化有限元模型,在模型中采用了基于断裂能和单元特征长度的混凝土应力-应变关系,有限元分析获得的墙体侧向力-侧向总变形关系、弯矩-曲率关系与已有的他人试验结果吻合较好。对曲率二次积分求得弯曲变形,将总变形分解为弯曲变形和剪切变形两部分。结果表明,破坏模式为弯曲控制的双钢板-混凝土组合剪力墙在加载过程中弯曲刚度和剪切刚度均有退化,其剪切变形不宜采用弹性方法计算,且剪切变形占总变形的比例在变形过程中基本上为常数。对剪切变形在总变形中所占的比例进行了参数分析,结果表明 ...

, 2017 形状记忆高分子因可以保持临时形状、在外界刺激下又可恢复初始形状而具有广阔的应用前景。超分子化学为创造新型功能高分子材料提供了巨大空间,将超分子体系引入形状记忆高分子,将为传统形状记忆高分子注入新的生命力。本文利用可逆作用(超分子作用和动态化学键)作为动态交联点固定材料的临时形状,当受到外界刺激时,临时交联点被破坏,材料又恢复到初始状态,从而开拓了不依赖于热效应的形状存储方式;在此基础上,通过分子设计和聚合物结构设计,利用两种或多种可逆作用分别记录不同的临时形状,并通过调整刺激信号的输入顺序 ...

PFU微型生物群落监测中异养性指数的应用研究及其分形分析 [PDF]
, 2004 对常德和汉江的异养性指数(HI)进行了分形分析,表明异养性指数在二维空间分布具有自相似性.异养性指数数据点与化学综合污染指数(P)数据点在双对数坐标中分段拟合时,当常德和汉江的LogP分别小于0 602和0 493时,常德和汉江的分形维数分别为0 39332和0 74110;当常德和汉江的LogP大于0 602和0 493时,常德和汉江的分形维数分别为0 30678和0 27239.拐点的出现表明异养性指数的变化在两个尺度域内遵从着不同的规律.拐点尺度以前,分维数较高,表明群落组成复杂 ...

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Despite extensive research on policy diffusion, the ways in which policy attention influences this process remain underexplored. This study addressed this gap by distinguishing between three types of policy attention—political speeches, policy issuance and field visits—and investigating their differential impacts when delivered by central and ...

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.
