Research ArticleOpen accessIn the keywordsSex Identification and the Sex-Related Genes of Nipponia NipponFeilong Sun, Xuanfu Huang, Shuiyun YangSex identification in birds is necessary for studying their ecology, behavior and population dynamics and structure. This study was carried out to determine the sex of Nipponia nippon by a Polymerase Chain Reaction (PCR) method. The sexing universal primers of non-ratite birds were employed to amplify the sexing related genes and identify the sex of each individual. A 657 bp … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 2 · 30 May 2017 · 7,841 accessesView PDFCite
Research ArticleOpen accessIn the keywordsParametrical Tuning of Twisting GeneratorsAleksei F. Deon, Yulian A. MenyaevGenerators of uniformly distributed random numbers are broadly applied in simulations of stochastic processes that rely on normal and other distributions. In a point of fact, the uniform random numbers are actively used for applications that range from, modeling different phenomena such as theoretical mathematics and technical designing, to evidence-based medicine. This paper proposes a novel approach which consists of … …Journal of Computer Science, Vol. 12, Issue 8 · 7 Oct 2016 · 11,836 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSequence Stratigraphic Analysis from Well Logs of an X-Field, Niger Delta, NigeriaGodwin Omokenu Emujakporue, Alphonsus Joseph EyoThe sequence stratigraphic analysis of the area was studied using well log information in order to determine the lithostratigraphy, chronostratigraphy, possible reservoir sands, age and depositional environment of the study area for opportunities that will support exploration program. The depositional environment penetrated by the wells interpreted from log signatures gave three major facies association. The blocky and coarsening upward (funnel … …Current Research in Geoscience, Vol. 6, Issue 2 · 11 Jul 2016 · 13,975 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNonlinear Piecewise-Defined Difference Equations with Reciprocal Quadratic TermsRamadan Sabra, Saleem Shafiq Al-AshhabIn this study we consider the several types of piece-wise defined sequences. We prove some results concerning the behavior of the sequence. In some cases we prove that the terms repeat themselves in certain patterns and we prove in other cases that the terms grow monotonically after few terms and approaches infinity. …Journal of Mathematics and Statistics, Vol. 11, Issue 3 · 18 Nov 2015 · 6,762 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Efficient Distributed Bioinformatics Computing System for DNA Sequence Analysis on Encoding SystemMohammad Ibrahim Khan, Chotan SheelThis study provides an effective design of search technique of a distributed bioinformatics computing system for analysis of DNA sequences using OPTSDNA algorithm. This system could be used for disease detection, criminal forensic analysis, gene prediction, genetic system and protein analysis. Different types of distributed algorithms for the search and identification for DNA segments and repeat pattern in a given … …Current Research in Bioinformatics, Vol. 2, Issue 2 · 20 Dec 2013 · 6,931 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFast Algorithms for Discovering Sequential Patterns in Massive DatasetsS. Dharani, Justus Rabi, Nanda Kumar, DarlyProblem statement: Sequential pattern mining is one of the specific data mining tasks, particularly from retail data. The task is to discover all sequential patterns with a user-specified minimum support, where support of a pattern is the number of data-sequences that contain the pattern. Approach: To find a sequence patterns variety of algorithm like AprioriAll and Generalized Sequential Patterns (GSP) … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 7,280 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGenome Sequence Analysis: A SurveyHassan Mathkour, Muneer AhmadProblem statement: Sequence analysis problems are NP hard and need optimal solutions. Interesting problems include duplicate sequence detection, sequence matching by relevance, sequence analysis using approximate comparison in general or using tools i.e., Matlab and multi-lingual sequence analysis. The usefulness of these operations is highlighted and future expectations are described. Approach: This study described the concepts, tools, methodologies, algorithms being … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 6,830 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIdentification of Major Cultivable Aerobic Bacteria in the Oral Cavity of Malaysian SubjectsKoshy Philip, Wuen Yew Teoh, Sekaran Muniandy, Hashim YaakobCulture dependent and culture independent methods have shown that about 600 species of bacteria inhabit the human oral cavity. While some oral microorganisms have a direct link to dental caries, periodontal disease and halitosis, opportunistic pathogens may be responsible for systemic diseases such as bacterial endocarditis, aspiration pneumonia, osteomyelitis in children, preterm low birth weight, coronary heart disease and cerebral … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 7,990 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMAI Cancellation in DS/CDMA using a new Approach on WDSY. Jabrane, R. Iqdour, B. Ait Es said, N. NajaThe steeping chip weighting waveforms are used in Multiple Access Interference cancellation by emphasizing the received spreading signal, therefore, that allows to solve the problem of orthogonality for the chip waveforms. The goal of this study was to elaborate a useful method based on fuzzy systems to determine the despreading sequences weighted by the steeping chip weighting waveforms for Direct … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,884 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNeural Networks for Interferences Suppression in DS/CDMA with Rayleigh Fading Channel and Power Control ErrorY. Jabrane, R. Iqdour, B. Ait Essaid et al.The exponential chip weighting waveforms have been designed with the purpose of multiple access interferences (MAI) rejection based on the concept that the optimum despreading sequence in reference emphasizes the transitions in the received spreading signal of interest. The despreading sequence weighted by exponential chip waveforms was determined by only one parameter. The objective of this study, was to introduce … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 6,382 accessesView PDFCite
