Wildlife Letters, Volume 4, Issue 1, Page 23-31, March 2026.American badgers, a medium‐sized carnivore occurring in much of North America, are important predators in prairie landscapes though our understanding of their habitat use requirements in these areas is unclear. We used a multi‐scale approach to understand American badger habitat use at both local and landscape scales.

Dianci bileiqi, 2018 雷电可以在短时间内释放强大的电流,对人们的经济活动和生命财产安全有着重大的安全影响。对雷电进行监测和雷电预报,可以降低雷电的危害。本文旨在以大气电场作为预测依据对地闪雷电进行预警,首先讨论了大气电场预警特征的编码方法,然后利用BP神经网络实现预测模型。预测实验在3种编码方式下进行,结果表明:直接利用电场值预测未来电场的效果不佳,但是使用从时间窗口为30 min的电场中提取的6种指标作为特征,预测15 min后紧接着的15 min内是否有雷电事件发生的效果明显,证明了本方法具有雷电预警实效性。

Research of VAT Prediction in Tax Administration——Illustrated By the Case of Hainan Province [PDF]
, 2015 增值税收入分列我国中央和地方税收收入的第一位和第三位，全面“营改增”后，它将占我国各级政府财政收入的37%左右。过去，财政收入形势较好，各项财政支出基本能得到满足，随着经济增长步入中速增长阶段，以及一系列的减税措施相继出台，各项税收收入同步下滑。同时，财政支出下滑速度慢于财政收入，当前财政收入形势严峻。此外，根据大多数研究建议，“营改增”收入暂归地方的过渡措施最可能通过调整增值税的分享比例来解决，届时，受中央转移支付较多的海南、北京和重庆将严重受损，财政收入形势更加严峻。因此，有必要加强增值税的预测工作，

Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate
