{"title":"A High-Performance Genome-Wide Association Study Algorithm based on Analysis of Pairs of Individuals","authors":"Лев Владимирович Уткин, Ирина Львовна Уткина","doi":"10.15622/SP.58.1","DOIUrl":"https://doi.org/10.15622/SP.58.1","url":null,"abstract":"An extremely simple and high-performance genome-wide association study (GWAS) algorithm for estimating the main and epistatic effects of markers or single nucleotide polymorphisms (SNPs) is proposed. The main idea underlying the algorithm is based on comparison of genotypes of pairs of individuals and comparison of the corresponding phenotype values. It is used the intuitive assumption that changes of alleles corresponding to important SNPs in a pair of individuals lead to a large difference of phenotype values of these individuals. In other words, the algorithm is based on considering pairs of individuals instead of SNPs or pairs of SNPs. The main advantage of the algorithm is that it weakly depends on the number of SNPs in a genotype matrix. It mainly depends on the number of individuals, which is typically very small in comparison with the number of SNPs. Another important advantage of the algorithm is that it can detect the epistatic effect viewed as gene-gene interaction without additional computations. The algorithm can also be used when the phenotype takes only two values (the case-control study). Moreover, it can be simply extended from the analysis of binary genotype matrices to the microarray gene expression data analysis. Numerical experiments with real data sets consisting of populations of double haploid lines of barley illustrate the outperformance of the proposed algorithm in comparison with standard GWAS algorithms from the computation point of view especially for detecting the gene-gene interactions. The ways for improving the proposed algorithm are discussed in the paper.","PeriodicalId":53447,"journal":{"name":"SPIIRAS Proceedings","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74609262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The principles of the pulse components formation in the stray electromagnetic radiations from displays based on the DVI standard-based video data transfer and specific pulse components of structural interference are presented.

A detailed description is given for the dependences of the effectiveness indicator of structural interference on a number of frames of an image, accumulated in the technical tool for the interception of stray electromagnetic radiations, as well as for signal/noise to amplitude relation at the input of the technical interception tool. \u0000On the basis of the simulation results we have evaluated the effectiveness of applying structural interference on active noise systems.

Such deterministic indicators of stability (connectedness, a couple of connections, linear functional connectivity, the number of spanning trees) allow, albeit very approximately, to solve a complex of tasks related to the assessment of the reliability and survivability complex networks. Due to the rather simple analytical form of a linear functional connectivity for the synthesis of structures, it is possible to use the analytical method presented in the work. In this general formulation for the synthesis of connected graphs is formulated as the maximization of the linear functional connec-tivity for all possible graphs with a given number of edges, vertices, and with fixed values of their weighting coefficients.","PeriodicalId":53447,"journal":{"name":"SPIIRAS Proceedings","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81235235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A proposed solution is a robust modification of the backstepping approach with the similar controller design structure. The main changes are based on plant model transformations that make it possible to use the only one filer in control system and, along with it, an auxiliary loop method usage to disturbances evaluation and compensation. High-gain observers are used for unknown signals measuring together with their derivatives. Tracking errors and observation errors convergence with the adjustable accuracy during the finite transient time is proved. Efficiency of the algorithm is demonstrated using computer modeling in comparison with an analogue.","PeriodicalId":53447,"journal":{"name":"SPIIRAS Proceedings","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77288765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As opposed to traditional computer-based systems, biological systems are often quite reliable. They have great self-protection mechanisms, highly scalable, adaptable and able to self regeneration.
