Politics &Policy, Volume 53, Issue 3, June 2025.ABSTRACT Deep fakes can be used for political advertising, enabling politicians to change their characteristic features or minimize deficits of their performances. Such a strategy may meet with great interest, which in some circumstances increases participation and might influence deliberation. It was applied in South Korea, and its variations appeared

Application of ultra-high gravity retaining walls in high fill slopes on karst developed foundations [PDF]
This paper presents a high fill slope solution for the steep and karst-developed terrain at the southern end, west side of Wulong Airport in Chongqing, where a combination of high embankment and ultra-high counterweight retaining wall was adopted.

Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Ecosystem state transitions can be ecologically devastating or be a restoration success. State transitions are common within aquatic systems worldwide, especially considering human‐mediated changes to land use and water use. We created a transferable conceptual framework to enable multiscale assessments of state resilience and early warnings ...

Influence of loading system stiffness on unstable failure mode and energy evolution of sandstone under lateral constraints [PDF]
In order to explore the influence of the stiffness of the loading system on rock failure mode and energy evolution law, the self-developed rigidity and variable stiffness test system is used to carry out biaxial compression tests, and the mechanism of ...

Experimentally testing animal responses to prescribed fire size and severity
Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Deserts are often highly biodiverse and provide important habitats for many threatened species. Fire is a dominant disturbance in deserts, and prescribed burning is increasingly being used by conservation managers and Indigenous peoples to mitigate the damaging effects of climate change, invasive plants, and land‐use change. The size, severity,

Zhendong Ceshi yu Zhenduan为了研究空心板梁桥抗爆性能，在任意拉格朗日‑欧拉（arbitrary Lagrange‑Euler，简称ALE）多物质流固耦合理论基础上，使用LS‑DYNA软件对空心板梁桥爆炸问题进行求解分析。通过模拟试验梁爆炸来验证模拟方法的准确性，从不同TNT当量、横截面上不同典型爆点部位和不同爆点区域等方面对空心板梁桥的损伤过程、压力场和动力响应进行参数化分析，以研究空心板梁桥的破坏模式和损伤情况。结果表明：爆炸冲击波进入空心板梁的空心室后，会在空心室内聚集，超压峰值因约束效应而增大，空心板底部很薄则很容易被击穿，
