A note on properties that imply the fixed point property
Abstract and Applied Analysis, 2006 We give relationships between some Banach-space geometric properties that guarantee the weak fixed point property. The results extend some known results of Dalby and Xu.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Psychological safety (PS) is essential for teamwork, communication, and patient safety in complex healthcare environments. In pediatric oncology, interprofessional collaboration occurs under high emotional and organizational demands. Low PS may increase stress, burnout, and adverse events.

Some Common Fixed Point Theorems in Generalized Metric Spaces
Journal of Mathematics, 2013 First we prove common fixed point theorems for weakly compatible maps which generalize the results of Chen (2012). Secondly, we prove common fixed point theorems using property E.A. along with weakly compatible maps.

New directions in Nielsen-Reidemeister theory [PDF]
, 2008 The purpose of this expository paper is to present new directions in the classical Nielsen-Reidemeister fixed point theory. We describe twisted Burnside-Frobenius theorem, groups with $R_\infty$ \emph{property} and a connection between Nielsen fixed ...

Kadec–Klee property and fixed points
Journal of Functional Analysis, 2014 In [Fixed Point Theory 11, No. 1, 125--128 (2010; Zbl 1228.47050)], \textit{B. Ricceri} proved that, if \(X\) is an infinite-dimensional reflexive Banach space with the Kadec-Klee property, then, for every compact function \(f:S_X\to X^*\) with \(\inf_{x\in S_X} f(x)>0\), there exists \(\hat{x}\) in the unit sphere \(S_X\) of \(X\) such that \(\langle ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Organoids in pediatric cancer research
FEBS 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.

APPROXIMATE FIXED POINT PROPERTY IN IFNS
, 2022 In this paper, we define concept of approximate fixed point property of a function and a set in intuitionistic fuzzy normed space. Furthermore, we give intuitionistic fuzzy version of some class of maps used in fixed point theory and investigate approximate fixed point property of these maps.
