文献阅读 [April 3rd]

本次阅读的三篇文献都是蜂学方面的新进展。我主要关心的是两方面问题:昆虫生理和行为特征的指标及测量方式(研究方法),以及熊蜂在环境胁迫下的反应机制(研究结论)。 Glass, J. R., Burnett, N. P., Combes, S. A., Weisman, E., Helbling, A., & Harrison, J. F. (2024). Flying, nectar-loaded honey bees conserve water and improve heat tolerance by reducing wingbeat frequency and metabolic heat production. Proceedings of the National Academy of Sciences, 121(4), e2311025121. https://doi.org/10.1073/pnas.2311025121 Focus on heat wave effects on honeybees Honeybees avoid overheating by lowering wingbeat frequency Reducing metabolic heat production is the result of lowering wingbeat frequency....

文献阅读 [March 6th]——人与自然耦合系统

这个礼拜潦草地阅读了几篇论文,在这里做一个简单的记录。理工科的学术研究永恒地在追寻新的前沿,我需要时刻和世界的发展保持同步。所以以后也希望能进一步推进文献阅读的深度和广度。 Liu, Jianguo, Thomas Dietz, et al. “Complexity of Coupled Human and Natural Systems.” Science, vol. 317, no. 5844, Sept. 2007, pp. 1513–16, https://doi.org/10.1126/science.1144004. Abstract: Integrated studies of coupled human and natural systems reveal new and complex patterns and processes not evident when studied by social or natural scientists separately. Synthesis of six case studies from around the world shows that couplings between human and natural systems vary across space, time, and organizational units....

Learning notes on agent-based modelling (ABM)

In this note I will give a brief introduction of agent-based modelling (ABM). I was learning ABM from an online tutorial1, in which this method is actually mostly applied in areas of social sciences, for example, economics or sociology. I will introduce the topic with four parts. For the first and second part, we will not talk about agriculture. But at last two parts we will talk about why agriculture experts need agent-based modelling....

SETAR Model

SETAR的全称是“Self-Exciting Threshold Auto-Regressive (SETAR) models”,可用于对一个时间序列变量的模式演变进行阶段划分。该模型最早于1977年由Howell Tong提出1。 ...
