A presumably mostly quadrupedal ankylopollexian iguanodontian, Bayannurosaurus perfectus gen. et sp. nov., is reported here, and is represented by an excellently well-preserved skeleton from the Lower Cretaceous Bayingebi Formation of Inner Mongolia, China. The diagnosis of the taxon includes several autapomorphies, notably a dorsally directed, strap-like posterodorsal process of the jugal and a horizontally oriented preacetabular process of the ilium. The nearly complete caudal series retains eight posterior-most caudals with procoelous, trapezoidal centra in dorsal view, and the last three caudals are fully fused. The discovery ofB. perfectus opens a critical new window on the early evolution and intercontinental dispersal of lguanodontia. The skeleton displays a transitional morphology between nonbadrosauriform ankylopollexians and Hadrosauriformes. A phylogenetic analysis indicates that Bayannurosaurus is positioned higher on the tree than Hypselospinus, but below Ouranosaurus just outside of Hadrosauriformes. The tree topology of Iguanodontia with temporal and spatial constraints reveals a possible biogeographic scenario supported by the statistical dispersal-vicariance analysis： around the J/K boundary, non-hadrosauriform ankylopollexians experienced multiple dispersal events from Europe to Asia, accompanying the coeval fall of the global sea level.

The Journal of Human Rights 2022年第5期21卷 908-933页

作者：阴建峰周恺 SU yilong(译) Law School of Beijing Normal University 不详

China’s policy of preserving the death penalty but controlling the death penalty strictly reflects the core value of striking a balance between the protection of human rights and the maintenance of social order. China has achieved remarkable results in strictly restricting the application of the death penalty in recent years, as reflected by the gradual reduction in the number of crimes punishable by death. To further promote human rights protection, China should gradually reform its death penalty policy by moving toward the goal of completely abolishing when the time is right, which requires continuous efforts at different levels across various stages.

由于产生了大量的塑性变形、摩擦热、氧化和组织结构演变,摩擦层的形成不仅影响着材料的摩擦磨损特性,还可能在摩擦条件和材料微观结构匹配合理的情况下引发自润滑行为。研究摩擦层和自润滑行为的微观机制可为在不加入添加剂的基础上,获得新的固态润滑方法及对应润滑机制提供重要的理论依据。对磨材料的强度、硬度、层错能高低等特性差异将导致摩擦层结构演化形式、细化程度和深度均有所不同。特别是诸如低碳条状马氏体钢和珠光体钢等钢铁材料,因其具有马氏体束、块、条和珠光体中的铁素体、先共析相、渗碳体等亚结构特征,摩擦层内部结构的演变又与其他材料有所区别。干摩擦自润滑通常是因为表面氧化物和纳米级氧化颗粒的保护所致,但是材料不同或材料包含的微结构不同,能够形成的氧化物或氧化颗粒的类型和尺度亦有所不同。国内外学者展开了大量有关摩擦层和自润滑行为的研究,他们从摩擦层内部材料冷作硬化、晶粒细化和动态再结晶等方面分析了摩擦层高应变引起的材料组织结构演变,以及不同微观组织材料所表现出的摩擦层和摩擦磨损特性差异。此外,还对摩擦引起的纳米晶/结构对材料摩擦磨损特性产生的影响展开了大量研究。最后,研究人员试图利用摩擦接触导致的高应变速率和高应变梯度来获得超细化晶粒以制备表层纳米结构和调控材料的摩擦磨损特性。本文从塑性变形、结构演变规律和力学性能等方面综述了摩擦层的最新研究进展,讨论了影响摩擦层内部塑性变形程度的摩擦外载条件因素。另外,从摩擦层内部形成纳米结构、梯度结构和由表面氧化物颗粒形成的自润滑层等方面讨论了干摩擦过程中产生的自润滑现象及对应机制。最后,探讨了如何利用材料表层结构设计和预制自润滑层以获得优异的耐磨性能。

使用定点离子束切割制样(FIB)并根据透射电镜(TEM)表征,分析了板条马氏体钢干摩擦层内部板条马氏体协调塑性变形、演变为纳米层片结构并发生非晶化的全过程。结果表明,高密度位错缠结和缺陷集中是纳米层片结构的典型特征,这种结构产生的界面在高应变驱动下发生非晶化。这些非晶产物,为进一步细化磨屑和形成表面自润滑层提供结构条件。基于上述实验结果并结合摩擦学和材料学理论建立了干摩擦过程中的非晶化形核模型,计算了发生非晶化的热力条件和能量壁垒。结果表明,根据经典形核理论和晶体向非晶转变的吉布斯自由能壁垒计算公式所建立的干摩擦非晶化形核能量模型,可用于计算发生非晶化必需的临界位错密度值。根据对应的计算结果,可控制摩擦条件用干摩擦应变诱导板条马氏体的固态非晶化。

As one of the most effective measures to extract useful information from medical database and provide scientific decision-making for diagnosis and treatment of diseases, medical data mining has become an increasingly hot topic in the last few years. Some of the intrinsic characteristics of medical databases, such as the huge volume and imbalanced samples as well as stringent performance standards, make this mining process particularly challenging. By elaborating various challenges existing in Task 1 of KDD Cup 2008 competition, this paper analyzes some potential solutions to these problems and presents a modified boosted tree as the final classification model. This model ranked the fourth among all the solutions to Task 1. We hope that our analysis and solutions to these challenges would contribute to the development of medical data mining applications.
