Abstract The development of music is a tortuous process, and the network relationship between each genre and each artist is intricate. In order to have a better understanding of the history of music, this paper tells the stories hidden in the history of music by means of data processing. Firstly, this paper establishes a model to evaluate the similarity between music by using ISOMAP algorithm. At the same time, the forest evolution model was established to mark the most revolutionary musical characters. Finally, using the Page-Rank algorithm, we get the founders of several music genres. It turns out that the figures who led the development of music don’t coincide with the figures who revolutionized music. Through the analysis of this paper, we can more clearly understand the development of music and the evolution of genres.

Background - Colonoscopy is an important diagnostic and therapeutic procedure. Adequate bowel preparation is mandatory. Several regimens were discussed in the literature. Among the drugs which has recently used, polyethylene glycol is one of the most popular agents. Objectives - The aim of this study was to compare efficacy of three different methods for 1 day preparation before colonoscopy. Methods - This study included children with the range of ages (2-21) who had an indication of colonoscopy. Exclusion criteria were based on the history of previous surgery, parental disagreement, and patients who did not use preparation protocol. Three methods for bowel preparation were studied: 1- Polyethylene glycol only; 2- Polyethylene glycol and bisacodyl suppositories; 3- Polyethylene glycol plus normal saline enema. Boston Bowel Preparation Score was used for evaluation of preparation. SPSS version 16.0 (Chicago, IL, USA) were used for data analysis. Results - In this study 83 cases completed the bowel preparation completely. Acceptable bowel preparation was seen in 24 (85.71%), 36 (94.73%), and 14 (82.35%) of cases in PEG, PEG + bisacodyl, and PEG + normal saline enema groups respectively. PEG + bisacodyl suppositories was more effective than PEG + normal saline for the preparation of the first segment ( P=0.05). For second and third segment of colon, BPPS score was higher in PEG + bisacodyl suppositories compared to other regimens, but this difference was not statistically significant. Conclusion - There was no significant difference between 1 day colonoscopy regimens in terms of bowel preparation score. Lowest score was seen in PEG + enema group compared to other group.

Recent advances in small-angle scattering (SAS) experimental facilities and data analysis methods have prompted a dramatic increase in the number of users and of projects conducted, causing an upsurge in the number of objects studied, experimental data available and structural models generated. To organize the data and models and make them accessible to the community, the Task Forces on SAS and hybrid methods for the International Union of Crystallography and the Worldwide Protein Data Bank envisage developing a federated approach to SAS data and model archiving. Within the framework of this approach, the existing databases may exchange information and provide independent but synchronized entries to users. At present, ways of exchanging information between the various SAS databases are not established, leading to possible duplication and incompatibility of entries, and limiting the opportunities for data-driven research for SAS users. In this work, a solution is developed to resolve these issues and provide a universal exchange format for the community, based on the use of the widely adopted crystallographic information framework (CIF). The previous version of the sasCIF format, implemented as an extension of the core CIF dictionary, has been available since 2000 to facilitate SAS data exchange between laboratories. The sasCIF format has now been extended to describe comprehensively the necessary experimental information, results and models, including relevant metadata for SAS data analysis and for deposition into a database. Processing tools for these files (sasCIFtools) have been developed, and these are available both as standalone open-source programs and integrated into the SAS Biological Data Bank, allowing the export and import of data entries as sasCIF files. Software modules to save the relevant information directly from beamline data-processing pipelines in sasCIF format are also developed. This update of sasCIF and the relevant tools are an important step in the standardization of the way SAS data are presented and exchanged, to make the results easily accessible to users and to promote further the application of SAS in the structural biology community.
