Emerging Risks and Housing Affordability Policy in Miami High‐Rises
ABSTRACT Recent advances in satellite‐based remote sensing and building performance measurement have raised critical questions regarding the long‐term settlement behavior of high‐rise structures situated on the complex subsurface of southeastern Florida.

观察到了长脉冲激光束辐照到铜薄片上产生的新的破坏模式.这种破坏可以分为三个阶段:鼓包,剪垣变形局部化及由冲塞所引起的贯穿,这种破坏模式的典型特征是鼓包和冲塞都是沿着入射激光相反的方向进行的,它同人们所塾知的激光引起材料破坏的分裂、烤化和汽化等不同 ...

ABSTRACT Climate disasters are currently changing territory around the world by showing large inequalities that exist in infrastructure systems, governance arrangements, and development pathways. In many cases, climate risk response strategies like managed retreat have been framed as practical approaches to respond to increasing climate disasters ...

ABSTRACT The escalating issue of drug‐resistant pathogens, largely driven by the overuse of conventional antibiotics, has become a significant global health threat. Developing alternative therapeutic strategies and fabricating natural biological enzyme materials that mimic the high efficiency, selectivity, and mild‐operating conditions of natural ...

The soil fungicide reduces the occurrence of pathogenic fungi in invaded soil and at the same time promotes the recruitment of mycorrhizal fungi and saprophytic fungi by the plants. The addition of biochar to the invaded soil has a negative legacy effect on subsequent invasive plants, while it exerts a positive enhancement effect on native plants ...

通过数值计算模拟了激光诱导充压柱壳的热力破坏效应,研究了典型结构的动态爆裂过程,获得的破坏模式与实验结果基本一致。给出了三类典型破坏模式及其对应的参数范围,探讨了各类破坏模式的形成机理,并分析了不同光斑尺寸、壳体厚度条件下热软化效应对破坏内压阈值的影响,以及预内压与破坏时间的关系。研究结果表明:光斑半径越大、热软化程度越高,柱壳的破坏内压阈值越低,且破坏内压阈值随着壳体厚度的减小呈线性下降;给定激光参数和壳体参数下破坏时间随预充内压增大而减小并呈二次函数关系 ...

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

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 ...

将有限体积法(FVM)与基于连续介质的离散元方法(CDEM)相结合,模拟了高桩码头在地震作用下的破坏模式。在验证了基于有限体积法的CDEM方法可行的基础上,选取了实际的高桩码头模型,采用EL-centro波模拟高桩码头在波动作用下的破坏演化过程,同时提取了梁顶关键的位移进行了详细的分析,得出了破坏过程的位移逐步变化 ...

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,
