The principle prerequisite for the formation of a volcano is the generation of a channel for magma transportation. There is little research on the deep mechanical mechanism for the formation of a magma transportation channel in the Tibetan plateau. Based on the subcrustal mantle convectiongenerated stress field inversed by gravity anomalies, together with its relationship to the Cenozoic volcanism in the plateau, and the mechanism of crustal fracture formation, as well as the numerical results of the evolution of mantle convection beneath the plateau, this paper investigates the deep mechanical mechanism for the formation of a magma transportation channel in the Tibetan plateau. There are two significant extensional convection-generated stress zones beneath the plateau, in which the volcanic rocks in the central and northern parts of the plateau are distributed. The Linzizong volcanism in southern Tibet correlates the upwelling mantle flow prior to the India-Asia collision or during the early stage of the collision. The magnitude of the stress is - 100 MPa, which is the same order of force that causes crustal fractures. The evidence implies that the mantle convection-generated stress is one of the principle causes of crustal fractures, and furthermore, the formation of the magma transportation channel in the Tibetan plateau.

在大数据时代,数据之间的紧密关联性是普遍存在的,图数据分析挖掘已经成为大数据技术的重要发展趋势。近几年,图神经网络作为一种新型的图表示学习工具引起了学术界和工业界的广泛关注。目前图神经网络已经在很多实际应用中取得了巨大的成功。最近人工智能的安全性和可信性成为了人们关注的重点,很多工作主要针对图像等规则数据的深度学习对抗攻击。文中主要聚焦于图数据这种典型非欧氏结构的黑盒对抗攻击问题,在图神经网络模型信息(结构、参数)未知的情况下,对图数据进行非随机微小扰动,从而实现对模型的对抗攻击,模型性能随之下降。基于节点选择的对抗攻击策略是一类重要的黑盒图对抗攻击方法,但现有方法在选择对抗攻击节点时主要依靠节点的拓扑结构信息(如度信息)而未充分考虑节点的特征信息,文中面向引文网络提出了一种基于特征拓扑融合的黑盒图对抗攻击方法。所提方法在选择重要性节点的过程中将图节点特征信息和拓扑结构信息进行融合,使得选出的节点在特征和拓扑两方面对于图数据都是重要的,攻击者对挑选出的重要节点施加不易察觉的扰动后对图数据产生了较大影响,进而实现对图神经网络模型的攻击。在3个基准数据集上进行实验,结果表明,所提出的攻击策略在模型参数未知的情况下能显著降低模型性能,且攻击效果优于现有的方法。

Dear editor,Training a logistic regression classifier is equivalent to solving a convex optimization problem, which is frequently solved with gradient descent (GD). As the gradient is computed using all the data, using GD is very time-consuming when the dataset is large [1, 2]. To accelerate the GD algorithm,stochastic gradient descent (SGD) estimates the gradient using only one training data point, which

Based on the negative exponential pair-potential （I/R）n, the interaction potential between the micro/nano planar curve and the particle located outside the curve is studied. We verified that, whatever the value of exponent n may be the potential of particle/plane-curve is always of unified curvature form. Furthermore, we proved that the driving forces acted on the particle may be induced by the highly curved micro/nano curve, and the curvature and gradient of curvature are confirmed to be the essential factors forming the driving force. Through the idealized numerical experiments, the accuracy and reliability of the curvature-based potential are examined.
