Dizhen xuebao, 2020 为了探索大容量气枪震源在探测区域结构以及在内陆水体进行水陆联测的可行性与有效性，2015年在安徽铜陵完成了长江航道走航激发、陆地接收反射波的“地学长江计划”铜陵段试验。本文从试验观测系统、共中心点分布、覆盖次数以及单炮数据属性等方面综合分析了大容量气枪震源陆地反射试验结果的影响因素。试验结果表明：① 大容量气枪震源在内陆水体激发能够用于地壳结构的探测；② 在水陆联测勘探中，根据目标层段合理设计反射角，能够有效地解决小炮检距反射角不足、大炮检距能量弱的问题；③ 在进行弯线数据采集时，需要对观测系统进行设计，

New Phytologist, Volume 247, Issue 2, Page 504-517, July 2025.Summary Repetitive DNA is a feature of all organisms, ranging from archaea and plants to humans. DNA repeats can be seen both in coding and in noncoding regions of the genome. Due to the recurring nature of the sequences, simple DNA repeats tend to be more prone to errors during replication and repair, resulting in variability in their unit length ...

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 3, Page 295-302, March 2025.ABSTRACT Objective Although artificial intelligence (AI) is increasingly being applied to ultrasound imaging in gynecology, efforts to synthesize the available evidence have been inadequate. The aim of this systematic review was to summarize and evaluate the literature on the role of AI applied to ultrasound imaging in benign gynecological disorders ...

The scope of empowerment for conservation and communities
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Conservationists increasingly position conservation that is mutually beneficial to people and biodiversity on the promise of empowerment of people through participatory discourse, metrics, processes, and outcomes. Empowerment represents multidimensional concepts and theories that permeate the interlinking levels of power, from the ...

World Water Policy, Volume 10, Issue 4, Page 1119-1161, November 2024.Abstract The present paper critically examines water‐assisted developmental projects and their associated conflicts through the lens of political ecology, with a particular focus on hydroelectric power generation in the Global South. These projects often catalyze localized socio‐cultural, political, and ecological tensions, especially in indigenous ...

Guangtongxin yanjiu, 2007 结构化对等（P2P,Peer to Peer）架构的资源搜寻算法如Chord、CAN、Pastry等的提出,改变了非结构化P2P架构的泛洪式资源搜寻的方式,降低了P2P资源搜寻信息的流量,从而增强了系统的扩展性。但是以上算法均未考虑到节点间实际物理距离对搜寻路径长度的影响。文章提出一种基于节点能力和节点区域性的结构化搜寻算法,该算法综合了CBT和Grapes的优点并充分考虑到节点的区域性以及节点能力,从而构建了一个短搜寻路径能力集包容的P2P系统。
