Coincidence and fixed points for compatible and relatively nonexpansive maps

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
The concept of relatively nonexpansive maps is introduced. Fixed point and coincidence results for families of four self maps of metric spaces are obtained.

COMMON FIXED POINTS OF COMPATIBLE MAPPINGS

open access: yesDemonstratio Mathematica, 1993
Extending results of the author [ibid. 23, No. 1, 213-218 (1990; Zbl 0731.54030)] and of \textit{B. E. Rhoades} [Some fixed point theorems for pairs of mappings, Jñānābha 15, 151-156 (1985)], some common fixed point theorems are established. Four mappings are involved satisfying a suitable expansive inequality in a complete metric space and a pairwise ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

On a fixed point theorem of Fisher and Sessa

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
A fixed point theorem of Fisher and Sessa is generalized by replacing the requirements of commutativity and nonexpansiveness by compatibility and continuity respectively.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Common Fixed Point Theorems in Menger Probabilistic Quasimetric Spaces

open access: yesFixed Point Theory and Applications, 2009

Weak contractive integral inequalities and fixed points in modular metric spaces

open access: yesJournal of Inequalities and Applications, 2016
Branciari (Int. J. Math. Math. Sci. 29(9):531-536, 2002) gave an interesting supplement of Banach’s contraction principle for an integral-type inequality.

COINCIDENCE POINTS OF WEAKLY COMPATIBLE MAPPINGS [PDF]

open access: yesBulletin of the Korean Mathematical Society, 2008
We present coincidence points and common fixed point re- sults for (f, g)-contractive mapping and (f, g)-nonexpansive mappings. Our results generalize and complement various known results existing in the literature.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

A common fixed point theorem in Menger space using implicit relation [PDF]

open access: yesSurveys in Mathematics and its Applications, 2013
The main purpose of this paper is to prove a common fixed point theorem for two pairs of weakly compatible mappings in Menger space using implicit relation.
