Fixed points of asymptotically contractive mappings

, 1992
Let X and Y be metric spaces. We say that a continuous mapping T: X → Y is asymptotically-k-contractive if limn, m; n ≠ md(Txn, Txm) ⩽ k limn, m; n ≠ md(xn, xm) for every sequence {xn} such that both limits exist.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Atanassov's intuitionistic contractive fuzzy negations

, 2010
In this work we consider the concept of contractive Atanassov's intuitionistic mapping. In particular, we show that with our definitions, the only strict (strong) contractive negation is the standard ...

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Best Proximity Point Results in Fuzzy Normed Spaces

Science and Technology Indonesia, 2023
Fixed point (briefly FP ) theory is a potent tool for resolving several actual problems since many problems may be simplified to the FP problem. The idea of Banach contraction mapping is a foundational theorem in FP theory.

Fixed point theorems on certain class of contractive mappings [PDF]

, 1988
The objective of this paper is to introduce the concepts of a H-contractive mapping and a π -ultimately contractive mapping on cartesian product of two metric spaces, and to show that, under certain restrictions, such mappings have a fixed ...

Exploring the influence of lactoferrin on wound healing and related signaling pathways: a systematic review

FEBS Open Bio, EarlyView.
Lactoferrin promotes wound healing by activating MAPK, PI3K/Akt, and extracellular matrix pathways, enhancing fibroblast remodeling, proliferation, and re‐epithelialization. These mechanisms highlight its therapeutic potential in inflammation control, tissue repair, and remodeling.

Weakly Contractive Mapping and Weakly Kannan Mapping in Partial Metric Space [PDF]

, 2019
In the article the concept of metric space could be expanded, one of which is a partial metric space. In the metric space, the distance of a point to itself is equal to zero, while in the partial metric space need not be equal to zero.The concept of ...

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

FEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.
