Multivalued Mizoguchi-Takahashi type rational contraction in relational metric spaces [PDF]

Surveys in Mathematics and its Applications, 2023
In this paper we establish a result in the fixed point theory of multivalued mappings. This is done by combining three prevalent trends in fixed point theory. Some consequences of the main theorem are discussed.

Binary relations and reduced hypergroups

Discrete Mathematics, 2008
Let \(H\) be a nonempty set, \(\mathcal P(H)^*\) the family of nonempty subsets of \(H\) and \(\cdot\) a hyperoperation in \(H\), that is, \(\cdot\colon H\times H\to\mathcal P(H)^*\). J. Jantosciak defined three fundamental equivalence relations on any hypergroupoid \((H,\cdot)\) as follows: Let \(x,y\in H\), then (i) \(x\) and \(y\) are said to be ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Thermodynamics of magnetized binary compact objects [PDF]

, 2010
Binary systems of compact objects with electromagnetic field are modeled by helically symmetric Einstein-Maxwell spacetimes with charged and magnetized perfect fluids. Previously derived thermodynamic laws for helically-symmetric perfect-fluid spacetimes

In vitro properties of patient serum predict clinical outcome after high dose rate brachytherapy of hepatocellular carcinoma

Molecular Oncology, EarlyView.
Following high dose rate brachytherapy (HDR‐BT) for hepatocellular carcinoma (HCC), patients were classified as responders and nonresponders. Post‐therapy serum induced increased BrdU incorporation and Cyclin E expression of Huh7 and HepG2 cells in nonresponders, but decreased levels in responders.

Relaxing the Φ-Family Auxiliary Functions and Related Results

Axioms
This article establishes the existence of fixed points and common fixed points for set-valued mappings satisfying an implicit-type contraction inequality involving a new auxiliary function in a complete metric space equipped with a binary relation ...

The ACS Survey of Galactic Globular Clusters. XII. Photometric Binaries along the Main-Sequence [PDF]

, 2011
The fraction of binary stars is an important ingredient to interpret globular cluster dynamical evolution and their stellar population. We investigate the properties of main-sequence binaries measured in a uniform photometric sample of 59 Galactic ...

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

Molecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Ample Spectrum Contractions and Related Fixed Point Theorems

Mathematics, 2019
Simulation functions were introduced by Khojasteh et al. as a method to extend several classes of fixed point theorems by a simple condition. After that, many researchers have amplified the knowledge of such kind of contractions in several ways.
