Dizhen xuebao, 2022 针对海啸危险性概率分析（PTHA）存在的较大不确定性问题，对不确定性产生来源进行了归纳和分类，提出了基于逻辑树与事件树方法合理量化不确定性的思路框架，并以马尼拉海啸潜源为研究对象，给出了量化震级上限、破裂面参数不确定的过程示例。数值模拟分析结果表明：海啸潜源震级上限的改变对危险性评估结果产生了显著影响，通过逻辑树方法可合理量化这种不确定性；地震破裂面的倾角、滑移角和破裂面积的随机不确定性对海啸危险性分析结果产生较为显著的影响，经事件树方法处理后的危险性结果保证率远高于20%，略低于80 ...

Protected areas on international borders show uneven conservation outcomes
Conservation Biology, EarlyView.Abstract Border protected areas (BPAs) are national protected areas that are immediately adjacent to a country's border or span two or more countries; they are characterized by distinctive opportunities and pressures. They play a critical role in protecting carbon‐rich ecosystems, conserving endangered biodiversity, reducing cross‐border environmental ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The immunosuppressive milieu of hepatocellular carcinoma (HCC) remains a major obstacle to durable antitumor responses. Mechanical‐energy‐driven piezocatalysis provides a noninvasive means of inducing oxidative damage and immunogenic tumor destruction; however, inefficient utilization of piezoinduced charges and insufficient localization of ...

Estimating the total mortality of seabirds following a marine heat wave
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.
