Fixed point results of weakly contraction mappings in partially ordered b-metric spaces
BMC Research Notes, 2022 Objectives We explored the results of fixed point, coincidence point and coupled coincidence point for the mappings in an ordered metric spaces. Our results generalized and extended the well-known results in the literature.

Holography for inflation using conformal perturbation theory [PDF]
, 2012 We provide a precise and quantitative holographic description of a class of inflationary slow-roll models. The dual QFT is a deformation of a three-dimensional CFT by a nearly marginal operator, which, in the models we consider, generates an RG flow to a

Discussion on some coupled fixed point theorems [PDF]
Fixed Point Theory and Applications, 2013 The authors survey a possible list of coupled fixed point results in ordered metric spaces which, by a method used presumably for the first time in [\textit{V. Berinde}, Nonlinear Anal., Theory Methods Appl., Ser. A, Theory Methods 74, No. 18, 7347--7355 (2011; Zbl 1235.54024)], can be reduced to known results for mappings with one variable.

RAD50 missense variants differentially affect the DNA damage response and mitotic progression
FEBS Letters, EarlyView.RAD50 incorporates into the MRN complex and initiates the DNA damage response. Furthermore, RAD50 promotes mitotic progression. RAD50 missense variants capable of forming an MRN complex supported the DNA damage response and mitotic features to different extents in complementation experiments, indicating these functions are separable and might impact ...

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)

Discovering and quantifying nontrivial fixed points in multi-field models [PDF]
, 2016 We use the functional renormalization group and the $\epsilon$-expansion concertedly to explore multicritical universality classes for coupled $\bigoplus_i O(N_i)$ vector-field models in three Euclidean dimensions.

On Some Coupled Quasi-fixed Points Theorems
Journal of Mathematical Analysis and Applications, 1996 The author discusses existence of fixed points and coupled quasi-fixed points of mixed monotone operators. Some special cases from [\textit{D. Guo} and \textit{V. Lakshmikantham}, Nonlinear problems in abstract cones, San Diego (1988; Zbl 0661.47045)] are also discussed.

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

, 2011 We study quantum modifications to cosmology in a Friedmann-Robertson-Walker universe with and without scalar fields by taking the renormalisation group running of gravitational and matter couplings into account.

Holographic RG flows with nematic IR phases [PDF]
, 2015 We construct zero-temperature geometries that interpolate between a Lifshitz fixed point in the UV and an IR phase that breaks spatial rotations but preserves translations.
