On the alignment of multiple time series fragments
نویسندگان
چکیده
We consider a local least-squares criterion for aligning multiple time series fragments differing by locations and show the consistency of the time-lag estimator and the asymptotic normality of the location estimator. We apply the criterion to the problem of aligning 50 glacial varve fragments and construct a 3000-year surrogate for global temperature. Some key words: Aligning time series; Asymptotics; Global warming; Lag estimator; Local least-squares; Varve chronology.

An Application of the ABS LX Algorithm to Multiple Sequence Alignment
We present an application of ABS algorithms for multiple sequence alignment (MSA). The Markov decision process (MDP) based model leads to a linear programming problem (LPP), whose solution is linked to a suggested alignment. The important features of our work include the facility of alignment of multiple sequences simultaneously and no limit for the length of the sequences. Our goal here is to ...

We present a multiple genome alignment browser for sequences from numerous multiple alignments. Our goal is to use information visualization to help users think about how sequences have evolved over time. Our application takes as input a series of multiple alignments in MAF format and outputs an interactive visual display of the data. 1 Information visualization Information visualization has in...
متن کاملMolecular and Bioinformatics Analysis of Allelic Diversity in IGFBP2 Gene Promoter in Indigenous Makuee and Lori-Bakhtiari Sheep Breeds
The aim of this study was to perform molecular and bioinformatics analysis of IGFBP2 gene promoter in association with some economic traits in indigenous Makuee (MS) and Lori-Bakhtiari (LB) breeds. DNA was extracted from blood samples of 120 MS and 200 LB and a 297 bp fragment from the upstream sequences of studied gene was amplified and genotyped by single-strand conformational polymo...
متن کاملMultiple Sequence Alignment Using Three- Dimensional Fragments
Background: Dialign is a DNA/Protein alignment tool for performing pairwise and multiple pairwise alignments through the comparison of gap-free segments (fragments) between sequence pairs. An alignment of two sequences is a chain of fragments, i.e local gap-free pairwise alignments, with the highest total score. METHOD: A new approach is defined in this article which relies on the concept of us...
