Quasi-greedy bases for sequences with gaps

open access: yesNonlinear Analysis, 2021
In this paper, we establish new advances in the theory started by T. Oikhberg in [15] where the author joins greedy approximation theory with the use of sequences with gaps. Concretely, we address and partially answer three open questions related to quasi-greedy bases for sequences with gaps posed in [15, Section 6].

بررسی بیوانفورماتیک ارتباط اندازه‌ی ژنوم با خصوصیات ژنتیکی و رفتاری باکتری‌های بیماری‌زا

open access: yesمجله دانشکده پزشکی اصفهان, 2014
مقدمه: با افزایش تعداد باکتری‌هایی که توالی‌یابی می‌شوند، نیاز به بهره‌برداری از این داده‌ها نیز بیشتر می‌شود. استفاده از این اطلاعات ژنومی از طریق به کارگیری هم‌زمان علوم بیوانفورماتیک و باکتری‌شناسی امکان‌ پذیر می‌باشد.

Contribution of nonconsensus base pairs within ArsR binding sequences toward ArsR-DNA binding and arsenic-mediated transcriptional induction

open access: yesJournal of Biological Engineering, 2019
Background A transcriptional reporter is the key component in bacterial biosensors which are employed to monitor the induction or repression of a reporter gene corresponding to environmental change.

Some integer sequences based on derangements [PDF]

open access: yesarXiv, 2007
Sequences whose terms are equal to the number of functions with specified properties are considered. Properties are based on the notion of derangements in a more general sense. Several sequences which generalize the standard notion of derangements are thus obtained.

Integrating alignment-based and alignment-free sequence similarity measures for biological sequence classification [PDF]

open access: yes, 2014
Alignment-based sequence similarity searches, while accurate for some type of sequences, can produce incorrect results when used on more divergent but functionally related sequences that have undergone the sequence rearrangements observed in many bacterial and viral genomes. Here, we propose a classification model that exploits the complementary nature

RY-Coding and Non-Homogeneous Models Can Ameliorate the Maximum-Likelihood Inferences from Nucleotide Sequence Data with Parallel Compositional Heterogeneity

open access: yesEvolutionary Bioinformatics, 2012
In phylogenetic analyses of nucleotide sequences, ‘homogeneous’ substitution models, which assume the stationarity of base composition across a tree, are widely used, albeit individual sequences may bear distinctive base frequencies.

The complete mitogenome and phylogenetic analysis of Japanese firefly ‘Genji Botaru’ Luciola cruciata (Coleoptera: Lampyridae)

open access: yesMitochondrial DNA. Part B. Resources, 2017
We performed mitogenome analysis of Japanese firefly Luciola cruciata (Coleoptera: Lampyridae), which is unique species in Japan. It is classified into six haplotypes based on the difference of COII sequence on mitochondrial DNA.

Evolution regularity of the Neogene shallow water delta in the Laibei area Bohai Bay Basin, northern China

open access: yesJournal of Palaeogeography, 2014
According to the characteristics of sedimentary microfacies, unique vertical depositional sequences and well logging response, the authors propose that a shallow water delta was widely developed in the Neogene of the Laibei area, Bohai Bay Basin of ...

Efficient multivariate sequence classification [PDF]

open access: yesarXiv, 2014
Kernel-based approaches for sequence classification have been successfully applied to a variety of domains, including the text categorization, image classification, speech analysis, biological sequence analysis, time series and music classification, where they show some of the most accurate results.

Synchronizable Checking Sequences Based on UIO Sequences [PDF]

open access: yes, 1996
This study addresses the synchronization problem that arises during the application of a predetermined checking sequence in some protocol test architectures that utilize remote testers. The synchronization problem can usually be solved by adding an additional communication channel or an additional protocol for coordination between the remote testers ...
