Fixed Points for Multivalued Mappings in b-Metric Spaces
Abstract and Applied Analysis, 2015 In 2012, Samet et al. introduced the notion of α-ψ-contractive mapping and gave sufficient conditions for the existence of fixed points for this class of mappings.

Remarks on Pseudo-Contractive Mappings [PDF]
Proceedings of the American Mathematical Society, 1970 Let X X be a Banach space, D ⊂ X D \subset X . A mapping U : D → X U:D \to X is said to be pseudo-contractive if for all u , v ∈ D u,v \in D and all r > 0

CONTRACTIBLE HAMILTONIAN CYCLES IN POLYHEDRAL MAPS [PDF]
Discrete Mathematics, Algorithms and Applications, 2012 We present a necessary and sufficient condition for existence of a contractible Hamiltonian cycle in the edge graph of equivelar maps on surfaces. We also present an algorithm to find such cycles (if they exist). This is further generalized and shown to hold for more general maps.

FEBS Open Bio, EarlyView.Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Positive contractive projections on noncommutative $\mathrm{L}^p$-spaces
, 2020 In this paper, we prove the first theorems on contractive projections on general noncommutative $\mathrm{L}^p$-spaces associated with non-type I von Neumann algebras where $1 < p < \infty$.

Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe
FEBS Open Bio, EarlyView.Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.

Fixed Point Results for Various α-Admissible Contractive Mappings on Metric-Like Spaces
Abstract and Applied Analysis, 2014 We establish some fixed point theorems for α-admissible mappings in the context of metric-like space via various auxiliary functions. In particular, we prove the existence of a fixed point of the generalized Meir-Keeler type α-ϕ-contractive self-mapping ...

, 2018 Important problems in wireless networks can often be solved by computing fixed points of standard or contractive interference mappings, and the conventional fixed point algorithm is widely used for this purpose.

Alcohol‐induced altered glycans in human tracheal epithelial cells promote bacterial adhesion
FEBS Open Bio, EarlyView.Alcohol induces altered glycans to promote bacteria adhesion. Heavy alcohol drinking is known to increase the risk of bacterial pneumonia. However, the link between alcohol levels and risk of infection remains underexplored. Recently, we found that alcohol induced α2‐6sialo mucin O‐glycans in human tracheobronchial epithelial cells, which mediated the ...

Open Mathematics, 2016 The aim of this paper is to introduce the concept of a new nonlinear multi-valued mapping so called weakly (α, ψ, ξ)-contractive mapping and prove fixed point results for such mappings in metric spaces.
