Upper Bound of Difference Operator on Some Matrix Domains

open access: yesJournal of Mathematical Sciences and Modelling, 2021
In this study, we investigate the norm of difference operator on some sequence spaces such as Hilbert and Cesaro matrix domains. Therefore the present study is a complement for those results obtained in [1].

Solvability of an infinite system of integral equations on the real half-axis

open access: yesAdvances in Nonlinear Analysis, 2020
The aim of the paper is to investigate the solvability of an infinite system of nonlinear integral equations on the real half-axis. The considerations will be located in the space of function sequences which are bounded at every point of the half-axis ...

Reduced space sequence alignment [PDF]

open access: yesBioinformatics, 1997
Sequence alignment is the problem of finding the optimal character-by-character correspondence between two sequences. It can be readily solved in O(n2) time and O(n2) space on a serial machine, or in O(n) time with O(n) space per O(n) processing elements on a parallel machine.

Binomial difference sequence spaces of order m

open access: yesAdvances in Difference Equations, 2017
In this paper, we introduce the binomial sequence spaces b 0 r , s ( ∇ ( m ) ) $b^{r,s}_{0}(\nabla^{(m)})$ , b c r , s ( ∇ ( m ) ) $b^{r,s}_{c}(\nabla^{(m)})$ and b ∞ r , s ( ∇ ( m ) ) $b^{r,s}_{\infty}(\nabla^{(m)})$ by combining the binomial ...

Intermolecular epistasis shaped the function and evolution of an ancient transcription factor and its DNA binding sites

open access: yeseLife, 2015
Complexes of specifically interacting molecules, such as transcription factor proteins (TFs) and the DNA response elements (REs) they recognize, control most biological processes, but little is known concerning the functional and evolutionary effects of ...

Fuzzy Entire Sequence Spaces [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
We first investigate the notion of fuzzy entire sequence space with a suitable example. Also we deal with the properties of the space of fuzzy entire sequences. The concepts of subset and superset of the fuzzy entire sequence spaces are introduced and their properties are discussed.

Almost Entropy Convergence for Fuzzy Sequence Spaces

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2018
In this paper, weintroduce a new type convergence called almost entropy convergence forsequences of fuzzy numbers. In addition this, we show that almost entropyconvergence can be defined as the intersection of convergence field of Cesàro matrix.

An Infinite System of Fractional Order with p-Laplacian Operator in a Tempered Sequence Space via Measure of Noncompactness Technique

open access: yesFractal and Fractional, 2021
In the current study, a new class of an infinite system of two distinct fractional orders with p-Laplacian operator is presented. Our mathematical model is introduced with the Caputo–Katugampola fractional derivative which is considered a generalization ...

OPEN QUESTIONS IN ORIGIN OF LIFE: EXPERIMENTAL STUDIES ON THE ORIGIN OF NUCLEIC ACIDS AND PROTEINS WITH SPECIFIC AND FUNCTIONAL SEQUENCES BY A CHEMICAL SYNTHETIC BIOLOGY APPROACH

open access: yesComputational and Structural Biotechnology Journal, 2014
In this mini-review we present some experimental approaches to the important issue in the origin of life, namely the origin of nucleic acids and proteins with specific and functional sequences.
