Implementation of the PageRank algorithm to rank web generally only contain static and dynamic pages, with the rapid url users then needed an algorithm for calculating web rankings. In determining the ranking of a web, links incoming and outgoing links are also random surfer model is one decisive factor in determining the ranking of a web. Implementation of PageRank on MATLAB formed on a program in the m-file.

Background: As a known key phrase extraction algorithm, TextRank is an analogue of PageRank algorithm, which relied heavily on the statistics of term frequency in the manner of co-occurrence analysis. Objective: The frequency-based characteristic made it a neck-bottle for performance enhancement, and various improved TextRank algorithms were proposed in the recent years. Most of improvements incorporated semantic information into key phrase extraction algorithm and achieved improvement. Method: In this research, taking both syntactic and semantic information into consideration, we integrated syntactic tree algorithm and word embedding and put forward an algorithm of Word Embedding and Syntactic Information Algorithm (WESIA), which improved the accuracy of the TextRank algorithm. Results: By applying our method on a self-made test set and a public test set, the result implied that the proposed unsupervised key phrase extraction algorithm outperformed the other algorithms to some extent.

SpiNNaker is a neuromorphic hardware platform, especially designed for the simulation of Spiking Neural Networks (SNNs). To this end, the platform features massively parallel computation and an efficient communication infrastructure based on the transmission of small packets. The effectiveness of SpiNNaker in the parallel execution of the PageRank (PR) algorithm has been tested by the realization of a custom SNN implementation. In this work, we propose a PageRank implementation fully realized with the MPI programming paradigm ported to the SpiNNaker platform. We compare the scalability of the proposed program with the equivalent SNN implementation, and we leverage the characteristics of the PageRank algorithm to benchmark our implementation of MPI on SpiNNaker when faced with massive communication requirements. Experimental results show that the algorithm exhibits favorable scaling for a mid-sized execution context, while highlighting that the performance of MPI-PageRank on SpiNNaker is bounded by memory size and speed limitations on the current version of the hardware.

Regional development differences are a universal problem in the economic development process of countries around the world. In recent decades, China has experienced rapid urban development since the implementation of the reform and opening-up policy. However, development differs across regions, triggering the migration of laborers from underdeveloped areas to developed areas. The interaction between regional development differences and Spring Festival has formed the world’s largest cyclical migration phenomenon, Spring Festival travel. Studying the migration pattern from public spatiotemporal behavior can contribute to understanding the differences in regional development. This paper proposes a geospatial network analytical framework to quantitatively characterize the imbalance of urban/regional development based on Spring Festival travel from the perspectives of complex network science and geospatial science. Firstly, the urban development difference is explored based on the intercity population flow difference ratio, PageRank algorithm, and attractiveness index. Secondly, the community detection method and rich-club coefficient are applied to further observe the spatial interactions between cities. Finally, the regional importance index and attractiveness index are used to reveal the regional development imbalance. The methods and findings can be used for urban planning, poverty alleviation, and population studies.

During the Pelagian controversy, the precise relation between grace and free will was an important issue. Augustine emphasized the priority of grace over human beings’ free will after the Fall. Pelagians such as Julian of Aeclanum were of the opinion that such view annihilated human beings’ free will. Throughout history, time and again, scholars belonging to different schools and denomina­tions have discussed this issue at length. In this article, we concentrate on Augustine’s view on love as grace during his debate with Julian. We argue that one should broaden the scope of this question and pay attention to the role of divine love as an important and decisive factor with regard to the proper activity of grace in the redemption and liberation of human beings. Thinking the relation between human beings and God in terms of love is a help in order to overcome the unfruitful grace-freewill antinomy. In fact, such approach does justice to both the Scriptural sources of Augustine’s position and the bishop’s spiritual view on the topic under consideration.

This chapter focuses on the manifestations and characteristics of right-wing terrorism in twentieth-century Europe, particularly on developments in Germany and Italy. When viewed from a comparative perspective, a central characteristic for right-wing terrorism is the Tatglaube, the faith in deeds. Although the worldview justifying such terrorism is grounded in racism, ethnocentrism, and nationalistic concepts of superiority, the decisive factor is violence as an end in itself, a violence that generally forgoes any justifying pattern of argument and strives to annihilate the enemy physically. The repertoire of actions taken and the formulized language of right-wing terrorism have remained largely unchanged throughout the twists and turns of twentieth-century history. Nevertheless, it is possible to differentiate various phases of right-wing terrorism, which were also influenced, in turn, by the political and societal environment. Despite the ethnocentric and nationalistic worldview from which this terrorism springs, it also becomes evident here that right-wing terrorism has always been marked by transnational influences, particularly since the end of the twentieth century.

Abstract This article explores the body as a site of subjectivity production during a hunger strike in Occupied Palestine. It further explores the former political prisoners’ theory of subjectivity as it emerges through their praxis and philosophy of freedom. Although the body is the principal tool that the hunger strikers use, they don't consider it the decisive factor in attaining their goal. For that they build on the immaterial strength that develops with the deterioration of the body and from which they construct the concept of rouh (soul). This is expressed through the formation of contradictory binaries: body versus soul and body versus mind. The article shows that the hunger strike not only is a political strategy for liberation; it also moves into a spiritualization of the struggle. It uses and problematizes Foucault's “technologies of the self” to theorize the specific formation of subjectivity in the Palestinian hunger strike under colonial conditions, and it contributes to theories of subjectivation. The hunger strikers, in their interaction with the dispossession of the colonial power, invent technologies of resistance to transcend the colonial and carceral constraints on their freedom and create the capacity for the transformation from a submissive subject to a resistant one.
