Defense performance Analysis of Rugby Union

Various performances profiling studies contributes to solve a problem and to verify concrete tasks in practical sport field (O’Donogue, 2005). As an acknowledgement of common and individual behaviours would be needed to present a more accurate representation of players’ contribution to performance (James, Mellalieu, & Jones, 2005), to raise the evidence to discuss defence, the current study focused on defensive turnover situations in the game and applied the social network analysis to organizational strategy. We focus on the defense performance analysis of rugby union. Rugby World Cup (RWC) is a rugby union tournament contested every four years between the top international teams and is one of the largest international sporting events in the world, surpassed in scale only by the FIFA-WC, The Olympics, and the Tour de France. The Seventh tournament is going to held in Japan in 2019

Defense performance analysis: social network analysis

This article discusses about the defense performance analysis of rugby union and introduces some analysis approaches. Rugby World Cup is a rugby union tournament contested every four years between the top international teams and is one of the largest international sporting events in the world, like FIFA-WC, The Olympic Games and the Tour de France. The Seventh tournament is going to held in Japan in 2019. After watching the three evidences, we will present some analytical approaches. Data were derived from 20 matches of close and balanced scores (under 20 points: results from cluster analysis according to game final score differences of 40 pool matches in 2011RWC). In these day’s rugby union games, the point balance under 20 points might be comparatively valid value as closed game. Double tackle contributor’s mapping by force-directed placement (degree centrality) at 2011 Rugby World Cup close games in pool matches. Centering Resonance Analysis would be one strong tool for understanding the total relationship structure of network graph, especially when the numbers of vertex has increased and complicated. Network analysis would be one cruel for understanding the complex sport scenes. We hope to keep discussing over the 2019 RWC / 2020 Tokyo Olympic games. We desire for making sport family in whole world and of course in Asian Friends

Time-dependent and Non-BPS Solutions in N=6 Superconformal Chern-Simons Theory

We study a class of classical solutions of three-dimensional N=6 superconformal Chern-Simons theory coupled with U(N) \times U(N) bi-fundamental matter fields. Especially, time evolutions of fuzzy spheres are discussed for both massless and massive cases. For the massive case, there are a variety of solutions having different behaviors according to the value of the mass. In addition to the time-dependent solutions, we analyze non-BPS static solutions which represent parallel M5/M5 or M5/anti-M5-branes suspended by multiple M2-branes. These solutions are similar to the fundamental strings connecting two parallel (anti) Dp-branes in perturbative string theory. A moving M5-brane and domain wall solutions with constant velocity that are obtained by the Lorentz boost of the known BPS solutions are briefly addressed.Comment: 27 pages, 9 figures, published version in JHE

Defence performance analysis: Social network analysis

There is little study concerned game structure of women’s sevens rugby. Because the game time is only 14 minutes (7 minutes half), the temporal performance would be a decisive factor. It might suggest the characteristics of current world women’s sevens rugby and each union. This study clarified the temporal structure of “try scoring rate” (frequency of tries in own possession (secs)), and “try conceding rate” (frequency of tries in oppose possession (secs)). With adding two manipulated factors from “opposition 22m entry try success (attack)” and “own 22m entry try success (defence)”, total four factors were investigated for the world ranking clusters. Data were picked up from opened homepage of World Rugby game analysis 2016-2017 women’s sevens series. Two-dimensional space showed the relationship of “try scoring rate” and “try conceding rate” (avg. = 79 secs) with mapping the world fifteen union’s performances. It suggested world ranking structure. Non-hierarchical cluster analysis was attempted in order to explore the possibility of grouping. Interesting differences were observed among the number of iterations. The 5-iteration process setting showed top group by top 7 unions. The 1000-iteration process setting showed top group by top 3 unions. (explained 96% of point variability). Clustering the world women’s sevens rugby was tried from the temporal structure analysis of some attack-defence performances. In non-hierarchical cluster analysis, the number of clusters needs to be determined by the analyst, and there is no established method to calculate the optimal number of clusters automatically. The number of women’s sevens games is also limited. Development of the optimal algorithm under this condition would be desired

Agile parallel bioinformatics workflow management using Pwrake

<p>Abstract</p> <p>Background</p> <p>In bioinformatics projects, scientific workflow systems are widely used to manage computational procedures. Full-featured workflow systems have been proposed to fulfil the demand for workflow management. However, such systems tend to be over-weighted for actual bioinformatics practices. We realize that quick deployment of cutting-edge software implementing advanced algorithms and data formats, and continuous adaptation to changes in computational resources and the environment are often prioritized in scientific workflow management. These features have a greater affinity with the agile software development method through iterative development phases after trial and error.</p> <p>Here, we show the application of a scientific workflow system Pwrake to bioinformatics workflows. Pwrake is a parallel workflow extension of Ruby's standard build tool Rake, the flexibility of which has been demonstrated in the astronomy domain. Therefore, we hypothesize that Pwrake also has advantages in actual bioinformatics workflows.</p> <p>Findings</p> <p>We implemented the Pwrake workflows to process next generation sequencing data using the Genomic Analysis Toolkit (GATK) and Dindel. GATK and Dindel workflows are typical examples of sequential and parallel workflows, respectively. We found that in practice, actual scientific workflow development iterates over two phases, the workflow definition phase and the parameter adjustment phase. We introduced separate workflow definitions to help focus on each of the two developmental phases, as well as helper methods to simplify the descriptions. This approach increased iterative development efficiency. Moreover, we implemented combined workflows to demonstrate modularity of the GATK and Dindel workflows.</p> <p>Conclusions</p> <p>Pwrake enables agile management of scientific workflows in the bioinformatics domain. The internal domain specific language design built on Ruby gives the flexibility of rakefiles for writing scientific workflows. Furthermore, readability and maintainability of rakefiles may facilitate sharing workflows among the scientific community. Workflows for GATK and Dindel are available at <url>http://github.com/misshie/Workflows</url>.</p

Square Root Singularity in Boundary Reflection Matrix

Two-particle scattering amplitudes for integrable relativistic quantum field theory in 1+1 dimensions can normally have at most singularities of poles and zeros along the imaginary axis in the complex rapidity plane. It has been supposed that single particle amplitudes of the exact boundary reflection matrix exhibit the same structure. In this paper, single particle amplitudes of the exact boundary reflection matrix corresponding to the Neumann boundary condition for affine Toda field theory associated with twisted affine algebras $a_{2n}^{(2)}$ are conjectured, based on one-loop result, as having a new kind of square root singularity.Comment: 10 pages, latex fil
