Evaluation of mixed-mode stress intensity factors by extended finite element method

Extended finite element method （XFEM） implementation of the interaction integral methodology for evaluating the stress intensity factors （SIF） of the mixed-mode crack problem is presented. A discontinuous function and the near-tip asymptotic function are added to the classic finite element approximation to model the crack behavior. Two-state integral by the superposition of actual and auxiliary fields is derived to calculate the SIFs. Applications of the proposed technique to the inclined centre crack plate with inclined angle from 0° to 90° and slant edge crack plate with slant angle 45°, 67.5° and 90° are presented, and comparisons are made with closed form solutions. The results show that the proposed method is convenient, accurate and computationallv efficient.

Towards Interaction,Communication and Integration of Ethnic Groups with Commonality:A Comparison of Inner Mongolia,Guangxi and Ningxia Autonomous Region

One crucial measure of strengthening and advancing the Party's work on ethnic affairs in the new era is to promote interaction,communication and integration of various ethnic groups,so as to enhance commonality.Entering the new era,Inner Mongolia,Guangxi and Ningxia have achieved remarkable results in encouraging interaction,communication and integration of various ethnic groups.By comparatively analyzing successes of the three autonomous regions through the perspective of promoting commonality,this article summarizes the following strategic revelations:1)we should comprehensively implement the Party's ethnic policies and ensure theactual implementation of mutual interaction,mutual communication and mutual integration of ethnic groups;2)we should proactively promote the substantial progress of the economy,so as to provide solid material foundation for mutual interaction,mutual communication and mutual integration of ethnic groups;3)we should facilitate activities that promote ethnic unity and progress,so that the promotion of interaction,communication and mutual integration of ethnic groups can be seen,be felt and gain actual outcomes;4)we should take measures that suit to local conditions and explore all-round embedding mechanisms in order to foster the ethos for mutual interaction,mutual communication and mutual integration of ethnic groups;5)we should make every effort to forge a strong sense of community for the Chinese nation and orient precisely to the cause of encouraging mutual interaction,mutual communication and mutual integration of ethnic groups.

"Xuhu"and"Danix":A Restudy on the Relationship between Salars and Tibetans

As a special inter-ethnic relationship and a unique cultural phenomenon,"Xuhu" and " Danix" exist in Xunhua Salars and surrounding Tibetans, which isparticularly close between Xichang Tibetans and Kewa Salars, located in BaizhuangTown, Xunhua County, Qinghai Province, and thus become a window to further explorethe relationship between Salars and Tibetans. This paper takes Xichang Valley as a fieldsite for digging deeply into the history and current situation of the relationship betweenSalars and Tibetans , finding that Tibetans in Xichang and Salars in Kewa have had formeda humane scene of interaction, communication and integration, in which they are based ona metaphor of common ancestry, and have long had the similar social structure, sharednatural resources and universal language and culture;They also regard credibility as thefoundation to offer mutual benefit, reciprocity and respect. Meanwhile, their interactionand communication contain a profound philosophical principle of " Harmony in Diversity", which is totally different from the variables to measure inter-ethnic relationships inWestern countries, and has provided a new perspective for us to explore the interactionand communication of ethnic groups in China.

中华各民族共有祖先崇拜神话研究

The ancestor worship myths of various ethnic groups in China constitute the common ancestor worship mythological system of the Chinese nation after long-term interactions,exchanges and integration.By conducting diachronic and synchronic comparative studies between ancestor worship myths of the people in the Central Plains and those of other ethnic groups in the Southwest and Northeast regions,and by applying a dual perspective to the common ancestor worship theme of these myths,we find that the common ancestor worship mythology shared by various ethnic groups in China is not only the historical expression of the sense of community for the Chinese nation,but also the natural result of long-term interactions,exchanges and integration between people of the Central Plains and ethnic groups in the Southwest and Northeast.The common ancestor worship mythology shared by different ethnic groups in China can provide strong spiritual cohesion in building a shared spiritual home for the Chinese people and in forging a strong sense of community for the Chinese nation.

Reevaluating the conceptual framework for applied research on host-plant resistance

Applied research on host-plant resistance to arthropod pests has been guided over the past 60 years by a framework originally developed by Reginald Painter in his 1951 book, Insect Resistance in Crop Plants. Painter divided the ＂phenomena＂ of resistance into three ＂mechanisms,＂ nonpreference （later renamed antixenosis）, antibiosis, and tolerance. The weaknesses of this framework are discussed. In particular, this trichotomous framework does not encompass all known mechanisms of resistance, and the antixenosis and antibiosis categories are ambiguous and inseparable in practice. These features have perhaps led to a simplistic approach to understanding arthropod resistance in crop plants. A dichotomous scheme is proposed as a replacement, with a major division between resistance （plant traits that limit injury to the plant） and tolerance （plant traits that reduce amount of yield loss per unit injury）, and the resistance category subdivided into constitutive/inducible and direct/indirect subcategories. The most important benefits of adopting this dichotomous scheme are to more closely align the basic and applied literatures on plant resistance and to encourage a more mechanistic approach to studying plant resistance in crop plants. A more mechanistic approach will be needed to develop novel approaches for integrating plant resistance into pest management programs.
