Common fixed points for generalized ψ-contractions in weak non-Archimedean fuzzy metric spaces
Applied General Topology, 2019 Fixed point theory in fuzzy metric spaces plays very important role in theory of nonlinear problems in applied science. In this paper, we prove an existence result of common fixed point of four nonlinear mappings satisfying a new type of contractive ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Cognitive impairment is a common non‐motor symptom in Multiple Sclerosis (MS), negatively affecting autonomy and Quality of Life (QoL). Innovative rehabilitation strategies, such as semi‐immersive virtual reality (VR) and computerized cognitive training (CCT), may offer advantages over traditional cognitive rehabilitation (TCR ...

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

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 ...

On the Generalized Roundness of Finite Metric Spaces
Journal of Mathematical Analysis and Applications, 1995 The generalized roundness introduced by P. Enflo for a metric space \((X,d)\) is the supremum \(gr (X,d)\) of all numbers \(q \geq 0\) such that \(\forall_n \geq 2\), \(\forall a_1, \dots, a_n\), \(b_1, \dots, b_n \in X\) one has: \[ \sum_{1 \leq i < j \leq n} \bigl( d(a_i, a_j)^q + d(b_i, b_j)^q \bigr) \leq \sum_{1 \leq i,j \leq n} d(a_i, b_j)^q ...
