从多中心、网络化、功能性多维视角，利用多元尺度的多源数据，研究粤港澳大湾区多维空间特征。研究发现：粤港澳大湾区多中心表现为明显的“三体性”与“圈层性”特征，网络化表现为明显的“强流动”和“节点性”特征，功能性表现为明显的“多样化”与“专业性”特征。粤港澳大湾区作为巨型城市区域在空间结构上表现出巨型都市网络的独特性，其背后形成机制则在于多元化的制度逻辑、相对“小尺度”的区域空间与要素高密度集聚、湾区分割的自然地理格局。基于以上独特性与形成机制，着眼于“一国两制”下建设高质量世界级城市群，提出了粤港澳大湾区多元融合发展的策略建议。

关键词：粤港澳大湾区高质量发展多维空间特征多元融合发展巨型都市网络

This paper proposes an automatic algorithm to determine the properties of stochastic processes and their parameters for inertial error. The proposed approach is based on a recently developed method called the generalized method of wavelet moments (GMWM), whose estimator was proven to be consistent and asymptotically normally distributed. This algorithm is suitable mainly (but not only) for the combination of several stochastic processes, where the model identification and parameter estimation are quite difficult for the traditional methods, such as the Allan variance and the power spectral density analysis. This algorithm further explores the complete stochastic error models and the candidate model ranking criterion to realize automatic model identification and determination. The best model is selected by making the trade-off between the model accuracy and the model complexity. The validation of this approach is verified by practical examples of model selection for MEMS-IMUs (micro-electro-mechanical system inertial measurement units) in varying dynamic conditions.

Non-coding RNA(ncRNA) has been a very active research area over the past 30 years. From small nc RNA – the discovery of RNA interference won the lead researchers the Nobel Prize, to long ncRNA(lncRNA), which has attracted much attention in recent years, various nc RNAs participate in all kinds of biological processes and show a variety of biomedical application prospects.
