标题： Identification of possible differences in coding and non-coding fragments of DNA sequences by using the method of the Recurrence Quantification Analysis

摘要： 从Li等人的结果开始，1992年以来，人们对于在DNA序列中寻找长程相关性表现出浓厚的兴趣，因为这引发了关于内含子和含内含子基因作用的问题。在本文中，我们研究了两个序列。我们应用了递归定量分析（RQA）方法，该方法由Zbilut和Webber于1994年引入。我们在这里的重要结果是，Lmax和Laminarity在非编码序列中表现出非常大的值，相对于编码序列。因此，我们认为，许多作者所声称的内含子相对于外显子的更高长程相关性可能在这里得到解释，这是由于发现了Lmax和Laminarity的更高值。 显示英文摘要

摘要： Starting with the results of Li et al. in 1992 there is valuable interest in finding long range correlations in dna sequences since it raises questions about the role of introns and intron-containing genes. In the present paper we studied two sequences. We applied the method of the recurrence quantification analysis (rqa) that was introduced by Zbilut and Webber in 1994. The significant result that we have here is that both Lmax and Laminarity exhibit very large values in non coding respect to coding sequences. Therefore we suggest that there the claimed higher long range correlations of introns respect to exons from many authors may be explained here in reason of such found higher values of Lmax and of Laminarity.
