彝、藏同属藏缅语族,共享历史记忆、语言与“根基性”的许多文化习俗,自古以来两者之间的交往与交融从未间断,这在彝族的民间文献、口述传统及民俗仪式中体现得尤为明显。在此前的相关研究中,“噢祖”((?)op zzup)的词义常被释为“原住民”,而在今彝语口语中,该词特指现今的藏族,这一解释似乎已在专事彝文化研究的学术界和彝族民间形成了“共识”。实际上,“噢祖”一词作为族群概念是彝藏两族历史文化长期交流交融的结果,利用已经发现和整理出版的彝文文献资料对文本内的“噢祖”概念作系统性地梳理、分析并揭示其演变进程,对于我们从不同的角度认识彝藏两族的交融史或有裨益。本文以生活在大小凉山地区自称为“诺苏”((?)nuo su)的彝族对“噢祖”的历史的叙事与想象为研究对象。通过访谈毕摩和民间“德古”((?)ndep ggu),辅以“诺苏”的各类民俗和口述传统资料,并结合笔者作田野时搜集的《藏人喇嘛经》((?)op zzup la ma rre)《藏人塔尔经》((?)op zzup dap bu rre)《藏人棘补经》((?)op zzup jji bu rre)《藏人阿史经》((?)op zzup a shy rre)《瓦萨拉且经》(3 vap sa la qie rre)《藏人阿史防箭防矛经(?)》(op zzup a shy nji tur hxi tur)《防猴瘟经》((?)nyut na ndi su mgup)《驱鬼经》((?)nyit cy ndi su tep yy)《招兵经》((?)mot mgo tep yy)等文献,运用历史语言学等方法,对“噢祖”进行了较为系统性的研究。文章主要围绕文本和仪式,分别从“噢祖”的词源、世系源流及其在宗教和婚礼仪式中的呈现展开研究。第一章,基于清代(1881年)以来的彝文文献,探究“噢祖”在不同时代的内涵及概念的演变过程;第二章,探究“诺苏”对“噢祖”同源世系的认同及对“噢祖”世系的“虚拟”建构;第三章,从有关宗教和婚礼的仪式与文本中,探讨“噢祖”在“诺苏”民俗活动中的重要性;第四章,通过对流动和迁徙到凉山周边甚至更远的藏地的“诺苏”群体的实地调查,发现“噢祖”概念随着“诺苏”与藏族全面而紧密的日常交往,其内涵更真实和明确的指向“现实”的藏族。“噢祖”在彝语中可分为特指和泛指。特指主要出现在书面语中,在云、贵、川等地区发现的留传至今的清代彝文文献中有许多零散的记载。在这些文献中,均将“噢祖”描述为与彝族“德本”“德施”等氏族同源,按照这些文献的叙事方式,彝族在清末时已将“噢祖”视为一支他者族群。到了民国时期,受“国族”和“民族”等概念传播的影响,凉山地区的彝族精英(如岭光电)将“噢祖”译为“西番”,从而使“噢祖”在彝族知识界明确成为“藏族”的汉语对译。与此不同的是,在“诺苏”的民间社会中,对“噢祖”的使用具有泛指性,指称包括邻近游牧藏人在内的多个藏羌缅族族群,其中还包括从事农业的当代羌族、普米族、木雅藏族、嘉绒藏族、尔苏藏族等。综上所述,本文认为“噢祖”是凉山“诺苏”对藏族社会一种“虚实结合”的叙事模式:基于彝藏实际交往“事实”的讲述,构成了这一概念中“实”的方面;基于很大程度上是想象和有意构建的“噢祖”书写,构成了这一概念中“虚”的方面。凉山“诺苏”对“噢祖”叙事的“虚实”杂糅,体现了“诺苏”与藏族及周边其他族群的交往、交流、交融的动态历史。

High-pressure studies on heavy fermion systems

Chinese Physics B 2016年第7期25卷 47-57页

作者：陈晔翁宗法 Smidman michae 路欣袁辉球 Center for Correlated Matter and Department of Physics Zhejiang University

In this review article, we give a brief overview of heavy fermions, which are prototype examples of strongly correlated electron systems. We introduce the application of physical pressure in heavy fermion systems to construct their pressure phase diagrams and to study the close relationship between superconductivity（SC） and other electronic instabilities, such as antiferromagnetism（AFM）, ferromagnetism（FM）, and valence transitions. Field-angle dependent heat capacity and point-contact spectroscopic measurements under pressure are taken as examples to illustrate their ability to investigate novel physical properties of the emergent electronic states.

Protein Kinase Activity Changes in the Aging Brain

The aging process in mammals is correlated with changes in psychomotor performance, cognitive function, and ability to adapt to stress (Montgomery et al., 1982; Lorens et al., 1990). These changes may be related to alterations in neuronal tissue that occur during the aging process. The normal aging process may be conceived of as the neuronal cell’s increasing inability to maintain normal cellular function which ultimately results in a number of morphological and biochemical changes. Morphologically, there is a loss of neuronal cells with increasing age (Brizzee and

Study of Slope Stability Using the Bishop Slice Method: An Approach Combining Analytical and Numerical Analyses

引用

Open Journal of Applied Sciences 2023年第8期13卷 1446-1456页

作者： Koffi Judicael Agbelele Guy Oyeniran Adeoti Daniel Yémalin Agossou Gérard Gbaguidi Aïsse National School of Technical Education (ENSET) Lokossa Republic of Benin National University of Sciences Technology Engineering and Mathematics (UNSTIM) Abomey Republic of Benin Laboratory of Test and Studies in Civil Engineering (L2EGC) Abomey Republic of Benin Materials and Structures Laboratory (LAMS) Cotonou Republic of Benin

The importance of slope stability in civil engineering cannot be underestimated, as failure of these structures can result in significant damage to downstream infrastructure and property. In this study, we used the Bishop slice method, combining both an analytical approach and a numerical approach using the SLOPE/W module of the Geostudio 2018 R2 software. The results obtained from these two methods showed that increasing soil cohesion helps to improve slope stability. The safety coefficients obtained by the analytical method vary between 0.621 and 1.422, while those obtained by the numerical method vary between 0.622 and 1.447, for cohesion values ranging from 4 kPa to 20 kPa. The results obtained by these two methods show a linear relationship between the safety coefficients and soil cohesion. The equation of the analytical method is y = 0.0496x + 0.4407, while that of the numerical method is y = 0.0512x + 0.4357. The results of the analytical approach indicate that a safety coefficient of 1.5 is reached when the cohesion reaches a value of 22 kPa, while the numerical approach shows a safety coefficient of 1.5 reached at a cohesion of 21 kPa. The difference between these two cohesion values can be explained by the number of slices used, which is smaller in the analytical method. However, the equation derived from the analytical method can be used as a general guide to assess the evolution of the safety coefficient of an overloaded slope in long-term behaviour with an increase in cohesion. However, it is important to stress the importance of verification using specialised software based on the finite element method.

For vision-based ETA obstacle detection system, this paper presents a novel obstacle detection method based on motion template. The novel method extracts MHI from the silhouette of objects, and then detects the moving obstacle’s position and direction and report a warning. Our experiments show that the method can detect moving and immobile obstacles, so long as the obstacle has movement relative to the camera. And this method is robust in different weather conditions and road textures.
