Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Taxonomic and functional diversity of urban bees of the world
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Estimating the total mortality of seabirds following a marine heat wave
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

针对输气干线优化设计属于约束非线性混合离散变量优化设计问题,采用以并行计算为基础的连续型Hopfield神经网络进行求解,将实际问题的优化解与神经网络的稳定状态相对应,把实际问题的优化过程映射为神经网络系统的演化过程。结果表明,CHNN算法能显著减小计算量,降低求解模型的计算复杂度,其优化效果优于模拟退火算法和方案比较法,可在保证各项约束的前提下,达到投资最小化,对输气干线优化设计和设计方案的优选具有一定的工程指导意义。
