Non-adiabatic dynamical calculations are carried out for the Na(3 p)+HD(ν = 1, j = 0)→NaH/NaD+D/H reaction on the diabatic potential energy surfaces of Wang et al.(Sci. Rep. 2018, 8, 17960) by using the time-dependent wave packet method. The state-to-state integral cross sections and differential cross sections of two reaction channels(NaH/NaD+D/H)are calculated for collision energy up to 0.4 eV. The cross section branching ratio indicates that the dominant reaction channel changes from NaD+H to NaH+D when the collision energy is larger than 0.227 eV. The products from two reaction channels both prefer to form in vibrationally cold but rotationally hot states, and they both tend to forward scattering.

A chemical process may involve multiple adiabatic electronic states, and non-adiabatic couplings play an important role in the reaction mechanism. In this work, the effect of non-adiabatic couplings in the H+MgH;→Mg;+H;reaction are studied using the time-dependent wave packet method and trajectory surface hopping method. The calculated results show that the reaction follows a direct abstraction process when the non-adiabatic couplings are neglected. However, when non-adiabatic couplings are included in the calculations, a longlived excited state complex(MgH_(2)+)*can be formed during the reaction. These direct and complex-forming reaction pathways are revealed by trajectory surface hopping *** non-adiabatic couplings induced complex-forming mechanism not only increases the reactivity but also has significant effect on the product vibrational state distribution.

This paper studies the imminent anomalies observed by the Sacks volume strainmeter in Erzhangying station and Tiantanghe station before 80 earthquakes with Ms≥ 7. 0 which took place from January 2011 to April 2014 all over the world. Then, preconditions for anomaly identification are put forward for complex earthquake cases. Statistical results show that volume strain observation has a better earthquake reflecting ability for earthquakes with magnitudes larger than 7. 0 and epicentral distance within 8000kin. In addition, these results also reflect that the volume strain observation can better reflect precursory anomalies of such earthquakes. Based on categorization and description of those anomalies, we divide the anomalies into three types, that is, earth tide distortion type, abrupt change type and slow earthquake type. Furthermore, the paper makes a statistical analysis of these types and preliminarily discusses their mechanical properties as well. According to research, volume strain anomaly has an indicative significance to future strong earthquakes in the world.

Target Tracking Based on SE-CNN and SiameseNet

Production of global land cover data-GLCNMO

第三十九届中国控制会议

作者： bayaer Saiyin Wenjie Chen School of Automation Beijing Institute of Technology Beijing Institute of Technology Chongqing Innovation Center

Recently, Siamese convolution neural networks have achieved remarkable results in the field of target tracking because of their balanced accuracy and speed. At the same time, Siamese convolution neural networks can solve the problem that the deep neural network can’t be updated in time and training data is insufficient. We propose an object tracking algorithm based on SE-CNN and Siamese convolution neural network. SE-CNN is added to the feature extraction submodule of SiameseRPN convolution neural network to enhance the quality of spatial encodings. During inference,a novel distractor-aware objective module is introduced to perform incremental learning. Benefit from the SE-CNN and distractor-aware objective module,Our algorithm performs well in the terms of accuracy and robustness in VOT2015,VOT2016,VOT2017 and OTB 2015.

决策树算法是一种非参数化、非线性的监督分类法。以2010年8月1日Landsat TM影像为基础遥感信息源,以内蒙古自治区赤峰市中部巴林右旗、林西县、克什克腾旗、翁牛特旗交汇处的区域为研究区,通过多次修改完善训练样本数据集,然后把6个原始波段和NDVI、主成分分析后的前3个主分量、常用8个纹理特征以及3个地形特征等共21个特征变量组合成5个不同特征变量组合,采用典型决策树算法C5.0进行了遥感影像分类实验,与最大似然分类结果进行对比。结果表明:C5.0决策树的分类结果优于最大似然结果,尤其是特征变量组合恰当的时候,能够有效利用相关辅助信息,因而最终的分类结果更能满足用户需求。
