针对动态多尺度图神经网络的编解码网络中存在的身体部位内部关节点间关联度不高和感受野受限制导致运动预测误差偏高的问题,提出了一种用于人体运动预测的多尺度全局自适应注意力图神经网络,降低运动预测误差。提出了一种划分骨架关节点的多距离分区策略,用于提高身体部位关节点信息在时间和空间上的关联程度;提出了全局自适应注意力时空卷积神经网络,以动态地加强网络对某一动作有贡献的时空关节点的关注度;将上述两处改进集成到图卷积神经网络门控循环单元中,以增强解码网络的状态传播性能,并降低预测误差。实验表明,与最新方法相比,该方法在Human 3.6M、CMU Mocap和3DPW数据集上的预测误差都有所下降。

“00后”大学生思想行为表现为理想信念较为明确,但世俗化特征凸现;价值理念网络多元,但人生价值迷失明显;道德观念认知良好,但伦理践行欠缺;个性特征张扬自信,但自我中心倾向突出;行为方式虚实结合,但实践精神欠缺。这些现象与时代大变迁、家庭教育、互联网技术发展等因素均有关。提出结合“00后”大学生思想行为的群体特点,整合课上课下、校内校外的教育资源,对其进行有针对性、时代性和系统性的思想引领、价值引导和人生指导,真正将其培养成新时代中国特色社会主义事业的合格建设者和可靠接班人。

Microstructural landscape of amorphous carbon

引用

National Science Review 2024年第5期11卷 94-95页

作者： Huiyang gou Center for High Pressure Science and Technology Advanced Research (HPSTAR)

Due to its diverse bonding hybridization forms (sp, sp2and sp3), amorphous carbon exhibits multifaceted properties and important application prospects, which have aroused extensive research interest[1–5]. In amorphous solids, some degree of atomic short-to medium-range order is thought to be ubiquitous, and the recent synthesis of new amorphous carbon has further increased our understanding of the atomic disorder in materials [4].

The Milky Way galaxy has long been hypothesized to contain at least 100 million black holes(BHs)that are lurking in the shadows[1]and 10 times more neutron stars(NSs).Xray and radio telescopes are traditionally employed to find outbursts of BHs or NSs;however,finding BHs or NSs in quiescence is extremely *** far,only a very small number of them[2]was found,pretty much like the tip of an iceberg,and finding more of them is quite hard using traditional methods.

Superhydrophobic Plant Leaves with Micro-line Structures： An Optimal Biomimetic Objective in Bionic Engineering

引用

Journal of Bionic Engineering 2018年第5期15卷 851-858页

作者： Xuelian gou Zhiguang Guo Hubei Collaborative Innovation Centre for Advanced Organic Chemical Materials and Ministry of Education Key Laboratory for the Green Preparation and Application of Functional Materials Hubei University Wuhan 430062 China State Key Laboratory of Solid Lubrication Lanzhou Institute of Chemical Physics Chinese Academy of Sciences Lanzhou 730000 China

It has been well demonstrated that there are two kinds of surface morphologies, including binary structures （namely micro-and nanostructures） and less common unitary structures （such as micro-line structures）, which play crucial roles in endowing the plant leaves with superhydrophobic properties. In this work, five superhydrophobic plant leaves in nature are introduced, by means of the combination of surface morphology and wettability with the aid of Scanning Electron Microscopy （SEM） and contact angle measurement. The results indicate that either the binary structures or the unitary structures enable the construction of a superhydrophobic surface, and the latter shows likely better mechanics compared with the former according to the corresponding theory. This research aims at introducing two different types of corresponding morphologies of superhydrophobic plant leaves.
