Representation of the world's biophysical conditions by the global protected area network
Conservation Biology, Volume 36, Issue 2, April 2022., 2022 Abstract Protected areas (PAs) are often implemented without consideration of already existing PAs, which is likely to cause an overrepresentation of certain biophysical conditions. We assessed the representativeness of the current PA network with regard to the world's biophysical conditions to highlight which conditions are underprotected and where ...

Key n‐Gram Extractions and Analyses of Different Registers Based on Attention Network
Journal of Applied Mathematics, Volume 2021, Issue 1, 2021., 2021 Key n -gram extraction can be seen as extracting n‐grams which can distinguish different registers. Keyword (as n = 1, 1‐gram is the keyword) extraction models are generally carried out from two aspects, the feature extraction and the model design.

Shuitu Baochi Xuebao, 2021 为明确黄河干流头道拐水文站水沙运动过程、变化趋势及运动状态特征，以2006—2018年黄河干流头道拐水文站水沙数据为基础，基于累积距平法、R/S极差分析法、河道来沙系数与不协调度等研究方法，对头道拐水文站水沙运动过程进行系统分析。结果表明：头道拐水文站年际间径流与输沙量和年内月均径流与输沙量变化趋势均呈现良好的一致性，但两者的季节性差异特征显著，且输沙量的显著性较径流更突出；冬季径流与输沙量变化趋势同步性相比其他季节较差 ...
