, 2019 北极阿拉斯加北坡盆地是全球开展天然气水合物的调查研究最早的地区之一,对全球天然气水合物的研究具有示范作用。在大量文献资料综合分析的基础上,本文系统归纳了阿拉斯加北坡地区天然气水合物的成矿地质条件和成矿规律。认为阿拉斯加北坡的天然气水合物成矿系统是下伏下白垩第三系含油气系统在浅部的衍生,是由下伏气源、断裂、岩性、北极的特殊环境(永久冻土、地层温压场)等多种因素共同作用的结果。通过模拟计算和分析,将阿拉斯加北坡地区划分了3级远景资源区,估算出整个阿拉斯加地区的天然气水合物资源为6.0×10^12 m ...

, 2018 北极黄河站位于北极斯瓦尔巴群岛新奥尔松地区,是生态系统对全球变化响应监测与研究的理想之地。我国自2004年建站以来,开展了系统的王湾海域生态断面和陆地植被样方的长期监测与研究,同时开展了环境污染和鸟类种群变迁等方面的考察与研究。结果表明:冰川退缩迹地上的物种更替明显,而范氏藓等可很好地反映该地区同时期的气温变化;从北极黄河站周边区域的海底沉积物、土壤、湖沉积物和冰川冰碛中分离获得了3个北极新属和21个北极新种,并发现了部分活性菌株;王湾海域微型浮游生物存在较高的生物多样性,其表层水存在潜在氮限制 ...

Conservation Biology, EarlyView.Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...

Beyond Evidence: How Framing Shapes Public Health Policies During Health Crises
Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT Does the level of evidence that accompanies policy action depend on how a problem is framed, and on who frames it? This article examines these questions in the context of health crises. Bridging sociological and equivalence framing theories, it treats frames as preexisting interpretive schemes shared within communities of actors, whose ...

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

The Evolution of Metal Halide Perovskite Transistors
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Metal halide perovskites (MHPs) offer a revolutionary pathway for next‐generation field‐effect transistors (FETs) because of their exceptional carrier mobilities and cost‐effective processability. However, their transition to practical electronics is significantly challenged by intrinsic instability and imbalanced charge transport. This review

Hybrid Flexible–Soft Neural Interface as a Practical Solution for Long‐Term Implants
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Implantable neural interfaces face persistent challenges in long‐term functionality due to chronic immune responses, mechanical mismatch with tissue, and material corrosion in vivo. The commonly used flexible materials, such as polyimide and parylene‐C (poly[monochloro‐p‐xylylene]), have advantages in low water vapor permeability and high ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Cisplatin‐related acute kidney injury (CP‐AKI) is a serious complication of cisplatin (CP) treated patients with cancer with high morbidity and mortality rates. It is directly related to the abnormal accumulation of CP in renal tubular epithelial cells, causing metabolic toxicity, DNA damage, and oxidative stress.

World Medical &Health Policy, Volume 18, Issue 3, September 2026.ABSTRACT This study examines the association between catastrophic health expenditure (CHE) and distress financing among India's uninsured “missing middle,” a population largely excluded from public insurance schemes and private coverage. While healthcare‐induced financial hardship is well documented, evidence on subsequent coping strategies among this ...
