Applications of some fixed point theorems for fractional differential equations with Mittag-Leffler kernel

Advances in Difference Equations, 2020
Using some fixed point theorems for contractive mappings, including α-γ-Geraghty type contraction, α-type F-contraction, and some other contractions in F $\mathcal{F}$ -metric space, this research intends to investigate the existence of solutions for ...

Stabilization of a fractional-order chain of integrators: a contraction-based approach [PDF]

, 2013
In this paper, stabilization of a chain of fractional-order integrators is attempted. The stability is proved using contraction analysis.

Safety of Daprodustat for the Treatment of Chronic Kidney Disease Anemia: Final Analysis of a Multicenter Postmarketing Surveillance Study in Japan

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This final analysis of a multicenter, prospective postmarketing surveillance study evaluated the safety of daprodustat in patients with chronic kidney disease anemia in routine clinical practice in Japan. Methods Patients who initiated daprodustat between September 2020 and July 2022 were registered.

Fixed points of some set-valued F-contractions

Journal of Nonlinear Sciences and Applications, 2016
Summary: Fixed point theorems of several set-valued \(F\)-contractions without using the Hausdorff metric are provided. Our results extend substantially the results due to \textit{S. B. Nadler jun.} [Pac. J. Math. 30, 475--488 (1969; Zbl 0187.45002)] and \textit{N. Mizoguchi} and \textit{W. Takahashi} [J. Math. Anal. Appl. 141, No.

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 ...

Remarks on Some Results of Extended Interpolative Hardy-Rogers-Geraghty-Wardowski Contractions and Ćirić-Reich-Rus Type F-Contractions [PDF]

Sahand Communications in Mathematical Analysis
In this paper, we improve the previous results from fixed point theory related to four types of contractions: interpolative Kannan contraction, extended interpolative and Geraghty type contraction, interpolative Hardy-Rogers contraction and Wardowski F ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

Molecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Fixed point results for β - F-weak contraction mappings in complete S-metric spaces

Vojnotehnički Glasnik
Introduction/purpose: This paper introduces the concept of β - F-weak contraction by using the concepts of F-weak contraction and a - pscontraction. Methods: The use of the β - F-weak contraction proves some fixed points theorems in the framework of S ...
