Weakly compatible maps in fuzzy metric spaces

open access: yesKathmandu University Journal of Science, Engineering and Technology, 1970
In this paper, we prove common fixed point theorems for six self maps by using weakly compatibility, without appeal to continuity in fuzzy metric space. Our results extend, generalized several fixed point theorems on metric and fuzzy metric spaces.   Mathematics subject classification: 47H10, 54H25.

Greguš type fixed points for weakly compatible maps

open access: yesBulletin of the Belgian Mathematical Society - Simon Stevin, 2003
Two self maps \(A\) and \(S\) of a normed space \(X\) are called weakly compatible if \(Ax=Sx\) implies \(ASx=SAx\). Let \(F\) be the family of mappings \(\varphi:\mathbb{R}^{+}\rightarrow\mathbb{R}^{+}\) which are upper semicontinuous, nondecreasing and satisfying \(\varphi(t)0\).

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 ...

Probing three-body correlations in a quantum gas using the measurement of the third moment of density fluctuations

open access: yes, 2010
We perform measurements of the third moment of atom number fluctuations in small slices of a very elongated weakly interacting degenerate Bose gas. We find a positive skewness of the atom number distribution in the ideal gas regime and a reduced skewness

GENERAL FIXED POINT THEOREMS FOR WEAKLY COMPATIBLE MAPS

open access: yesDemonstratio Mathematica, 2005
Summary: The purpose of this note is to use general expansive and conditions minimal type commutativity without continuity requirements to prove some fixed point theorems. The theorems extend known results from the class of compatible continuous expansive maps to a wider class of mappings.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

On Some Generalizations of Commuting Mappings

open access: yesAbstract and Applied Analysis, 2012
It is shown that occasionally JH operators as well as occasionally weakly biased mappings reduce to weakly compatible mappings in the presence of a unique point of coincidence (and a unique common fixed point) of the given maps.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
