Research ArticleOpen accessEvery word in the titleA Novel 2D Graphical Representation and its Application in the Similarities/Dissimilarities Analysis of Protein SequencesXianyou ZhuIn this study, a novel 2D graphical representation of protein sequences is proposed based on the physicochemical feature pK2 of amino acids first and then, on the basis of the newly given 2D graphical representation, a new concept of feature appearance model is introduced to analyze the similarity/dissimilarity of protein sequences. Finally, Theoretical and simulation results show that the newly … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 17 Mar 2016 · 6,964 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenetic Algorithm Based Probabilistic Motif Discovery in Unaligned Biological SequencesM. Hemalatha, K. VivekanandanFinding motif in biosequences is the most important primitive operation in computational biology. There are many computational requirements for a motif discovery algorithm such as computer memory space requirement and computational complexity. To overcome the complexity of motif discovery, we propose an alternative solution integrating genetic algorithm and Fuzzy Art machine learning approaches for eliminating multiple sequence alignment process. Problem … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,729 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTaxonomically Clustering Organisms Based on the Profiles of Gene Sequences Using PCAE. Ramaraj, M. PunithavalliThe biological implications of bioinformatics can already be seen in various implementations. Biological taxonomy may seem like a simple science in which the biologists merely observe similarities among organisms and construct classifications according to those similarities[1], but it is not so simple. By applying data mining techniques on gene sequence database we can cluster the data to find interesting similarities … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,746 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleKorovkin and Weierstrass Approximation via Lacunary Statistical SequencesRichard F. Patterson, Ekrem SavaşIn this study we shall extended Korovkin and Weierstrass approximation theorem to lacunary statistical convergent sequences. In addition, to these approximation theorems, we established also introduced lacunary statistically convergent of degree β and establish a corresponding Korovkin type theorem namely the following: If the sequence of positive linear operators Pn: CM [a, b]→ B[a, b] satisfies the conditions: * ||Pn(1, … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,659 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleProtein Sequences Features Extraction for Predicting Beta- Turns and their Types: A ReviewMurtada Khalafallah Elbashir ElfakiBeta-turns are considered to be important secondary structure types that have essential role in molecular recognition, protein folding and stability. They represent 25% of protein structures, therefore they are the most common type of non-repetitive or tight turns structures. Their prediction is considered to be an important issue in bioinformatics and molecular biology, because it provides valuable information and inputs … …Journal of Computer Science, Vol. 15, Issue 9 · 1 Oct 2019 · 7,694 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSequences of Closed Operators and CorrectnessSabra Ramadan, Abdulla Al-HossainIn applications and in mathematical physics equations it is very important for mathematical models corresponding to the given problem to be correct given. In this research we will study the relationship between the sequence of closed operators An→A and the correctness of the equation Ax = y. Also we will introduce the criterion for correctness. …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,291 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTwister Generator of Random Normal Numbers by Box-Muller ModelAleksei F. Deon, Yulian A. MenyaevTwisting generators of the pseudorandom normal variables can use uniform random sequences as a basis. However, such technique could provide poor quality result in cases where the original sequences have insufficient uniformity or skipping of random values. This work offers a new approach for creating the random normal variables using the Box-Muller model as a basis together with the twisting … …Journal of Computer Science, Vol. 16, Issue 1 · 10 Jan 2020 · 11,556 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUniform Twister Plane GeneratorAleksei F. Deon, Yulian A. MenyaevRandom plane generators may use various types of the random number algorithms to create multidimensional planes. At the same time, the discrete Descartes random planes have to be uniform. The matter is that using the concept of the uncontrolled random generation may lead to a result of weak quality due to initial sequences having either insufficient uniformity or skipping of … …Journal of Computer Science, Vol. 14, Issue 2 · 26 Feb 2018 · 11,514 accessesView PDFCite
