Hyers-Ulam stability for coupled random fixed point theorems and applications to periodic boundary value random problems [PDF]
, 2019 In this paper, we prove some existence, uniqueness and Hyers-Ulam stability results for the coupled random fixed point of a pair of contractive type random operators on separable complete metric spaces. The approach is based on a new version of the Perov

Numerical renormalization group study of two-channel three-impurity triangular clusters
, 2009 We study triangular clusters of three spin-1/2 Kondo or Anderson impurities that are coupled to two conduction leads. In the case of Kondo impurities, the model takes the form of an antiferromagnetic Heisenberg ring with Kondo-like exchange coupling to ...

Existence theorems of coupled fixed points
Journal of Mathematical Analysis and Applications, 1991 Let D be a subset of a real partially ordered Banach space E. Let A: \(D\times D\to E\) be a mixed monotone operator (i.e. \(A(\cdot,y)\) is nondecreasing and \(A(x,\cdot)\) is nonincreasing). A point \((x^*,y^*)\in D\times D\) is called a coupled fixed point of A if \(x^*=A(x^*,y^*)\) and \(y^*=A(y^*,x^*)\). Let \(\tilde A:\) \(D\times D\to E\times E\)

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes
FEBS Letters, EarlyView.The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Fixed and coupled fixed point theorems of omega-distance for nonlinear contraction [PDF]
Fixed Point Theory and Applications, 2013 En este trabajo utilizamos la noción de Ω-distancia en el sentido de Saadati et al. (Math. Comput. Model. 52:797-801, 2010) para construir y demostrar algunos teoremas de puntos fijos y acoplados en un espacio G-métrico completo para una contracción no lineal. Además, proporcionamos un ejemplo para respaldar nuestros resultados. MSC:47H10, 54H25.

Mitochondrial fatty acid oxidation is stimulated by red light irradiation
FEBS Letters, EarlyView.Light at different wavelengths has distinct effects on keratinocyte viability and metabolism. UVA light abrogates metabolic fluxes. Blue and green light have no effect on metabolic fluxes, while red light enhanced oxidative phosphorylation by promoting fatty acid oxidation. Keratinocytes are the primary constituents of sunlight‐exposed epidermis.

Quadruple fixed point theorems for nonlinear contractions on partial metric spaces
Applied General Topology, 2014 The notion of coupled fixed point was introduced by Guo and Laksmikantham [12]. Later Gnana Bhaskar and Lakshmikantham in [11] investigated the coupled fixed points in the setting of partially ordered set by defining the notion of mixed monotone property.

Remarks on the Paper ``Coupled Fixed Point Theorems for Single-Valued Operators in b-Metric Spaces'' [PDF]
Mathematics Interdisciplinary Research, 2017 In this paper, we improve some recent coupled fixed point results for single-valued operators in the framework of ordered b-metric spaces established by Bota et al. [M-F. Bota, A. Petrusel, G. Petrusel and B.

Unified multi-tupled fixed point theorems involving mixed monotone property in ordered metric spaces
, 2016 In the present article, we introduce a unified notion of multi-tupled fixed points and utilize the same to prove some existence and uniqueness unified multi-tupled fixed point theorems for Boyd-Wong type nonlinear contractions satisfying generalized ...

Vacuolar transport and function of Saccharomyces cerevisiae sterol ester hydrolase Tgl1
FEBS Letters, EarlyView.Tgl1, one of yeast sterol ester hydrolases, had been found on the lipid droplets where sterol esters are mainly stored. This study revealed that Tgl1 is transported into the vacuole depending on the ESCRT‐I–III complex, and that it exhibits intra‐vacuolar sterol ester hydrolase activity.
