Some common fixed point theorems of p- contraction and (α, β) composition contraction in Generalized Banach space

open access: yesTikrit Journal of Pure Science, 2023
In this work, we introduce Some common fixed point theorems of  contraction and (α, ) composition contraction in Generalized Banach space. The provided theorem is a generalization and extension of many well-known theorems.

Balls in sequence spaces

open access: yesAutomatic Control and Computer Sciences, 2013
We introduce a new metric on a space of right-sided infinite sequences drawn from a finite alphabet. Emerging from a problem of entropy estimation of a discrete stationary ergodic process, the metric is important on its own part and exhibits some interesting properties.

On Certain Sequence Spaces [PDF]

open access: yesCanadian Mathematical Bulletin, 1981
AbstractIn this paper define the spaces l∞(Δ), c(Δ), and c0(Δ), where for instance l∞(Δ) = {x=(xk):supk |xk -xk + l|< ∞}, and compute their duals (continuous dual, α-dual, β-dual and γ-dual). We also determine necessary and sufficient conditions for a matrix A to map l∞(Δ) or c(Δ) into l∞ or c, and investigate related questions.

On Triple Difference Sequences of Real Numbers in Neutrosophic Normed Spaces

open access: yesCommunications in Advanced Mathematical Sciences, 2022
The aim of this article is to investigate triple $\Delta $-statistical convergent sequences in a neutrosophic normed space (NNS). Also, we examine the notions of $\Delta $-statistical limit points and $\Delta $-statistical cluster points and prove their ...

Some normed binomial difference sequence spaces related to the ℓ p $\ell_{p}$ spaces

open access: yesJournal of Inequalities and Applications, 2017
The aim of this paper is to introduce the normed binomial sequence spaces b p r , s ( ∇ ) $b^{r,s}_{p}(\nabla)$ by combining the binomial transformation and difference operator, where 1 ≤ p ≤ ∞ $1\leq p\leq\infty$ .

Deep learning enables therapeutic antibody optimization in mammalian cells by deciphering high-dimensional protein sequence space

open access: yesbioRxiv, 2019
Therapeutic antibody optimization is time and resource intensive, largely because it requires low-throughput screening (103 variants) of full-length IgG in mammalian cells, typically resulting in only a few optimized leads.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

BOOL-AN: A method for comparative sequence analysis and phylogenetic reconstruction [PDF]

open access: yes, 2009
A novel discrete mathematical approach is proposed as an additional tool for molecular systematics which does not require prior statistical assumptions concerning the evolutionary process.
