Regulating Reality: Exploring Synthetic Media Through Multistakeholder AI Governance
Policy &Internet, Volume 18, Issue 3, September 2026.ABSTRACT Artificial intelligence's integration into daily life has brought with it a reckoning on the role such technology plays in society and the varied stakeholders who should shape its governance. This is particularly relevant for AI‐generated, or synthetic, media, an emergent visual technology impacting perceptions of media as records of reality ...

Out of Sight, Out of Mind? The Impact of Issue Proximity on Policy Choice at the Individual Level
Review of Policy Research, Volume 43, Issue 5, September 2026.ABSTRACT Scholars have extensively studied the link between issue definition and policy choice. However, empirical evidence on the role of issue proximity on policy support at the individual level remains scarce. The study draws on policy and management literatures to examine whether framing an issue as more or less spatially proximate to an individual

Shuitu Baochi Xuebao, 2004 从适用于陡坡的水动力学模型出发,研究坡面水流细沟侵蚀临界状态的判断方法。讨论了坡长、坡度、坡面投影长对细沟侵蚀的影响,采用临界摩阻流速随坡度变化、临界摩阻流速不随坡度改变两种假定分别进行模拟计算,以摩阻流速作为判别坡面细沟流侵蚀临界状态的水动力学指标,在给定的坡面尺寸、净雨强和初始微地形条件下,计算得出了细沟流摩阻流速达到临界值时所对应的坡度。

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The limited crack resistance of coarse grain boundaries and coarse interfaces leads to an incompatibility between high‐temperature strength and ductility in TiAl alloys. Tailoring stress‐oriented textures and multiscale heterogeneous interfaces can effectively impede crack propagation, thereby overcoming this trade‐off.

Glycerophosphocholine‐Mediated Dual Regulation for Highly Stable Aqueous Iron‐Ion Batteries
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Iron‐ion batteries (FeIB) offer the advantages of low cost and high capacity, demonstrating potential for large‐scale energy storage. However, severe hydrogen evolution reaction (HER) occurs during cycling, which significantly impacts battery lifespan.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...

Gaoya dianqi, 2011 XPLE电力电缆因其优异的机械性能和电绝缘性能得到广泛的使用,在交联电缆接头安装过程中,对交联聚乙烯主绝缘表面进行打磨会使接头交联聚乙烯—硅橡胶界面产生不同的粗糙程度,但是对存在于两个有机绝缘之间的接触面的电绝缘强度的研究很少,笔者针对交联聚乙烯电力电缆接头的交联聚乙烯和硅橡胶两绝缘界面经常出现放电光的现象,建立了电痕破坏实验平台,用不同型号的砂纸对XPLE片横向和纵向打磨制备实验样品,采用高速相机对发生在交联聚乙烯和透明硅橡胶界面上的放电光进行记录。结果表明:界面粗糙度越大 ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →
