A note on Picard iterates of nonexpansive mappings [PDF]
Annales Polonici Mathematici, 2001 Summary: Let \(X\) be a Banach space, \(C\) a closed subset of \(X\), and \(T:C\rightarrow C\) a nonexpansive mapping. It has recently been shown that if \(X\) is reflexive and locally uniformly convex and if the fixed point set \(F(T)\) of \(T\) has nonempty interior then the Picard iterates of the mapping \(T\) always converge to a point of \(F(T)\).

On the Convergence of Techniques that Improve Value Iteration [PDF]
, 2013 Prioritisation of Bellman backups or updating only a small subset of actions represent important techniques for speeding up planning in MDPs. The recent literature showed new efficient approaches which exploit these directions.

Journal of Function Spaces, 2019 In order to solve (partial) differential equations, implicit midpoint rules are often employed as a powerful numerical method. The purpose of this paper is to introduce and study a class of new Picard-Mann iteration processes with mixed errors for the ...

Strongly Convergence of Two Iterations For a Common Fixed Point with an Application
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2019 In this paper, we study some cases of a common fixed point theorem for classes of firmly nonexpansive and generalized nonexpansive maps. In addition, we establish that the Picard-Mann iteration is faster than Noor iteration and we used Noor ...

Inferring the Abundance of an Island Megaherbivore From Semi-Structured Distance Sampling. [PDF]
Ecol EvolWe use a hierarchical Bayesian distance‐sampling model to infer the atoll‐wide abundance and habitat‐specific density of Aldabra giant tortoises from long‐term, irregular transect monitoring on Aldabra Atoll (Seychelles). The detection‐corrected wet‐season estimate indicates a large, stable population of ~182,500 individuals (2018–2021), supporting the

Boundary Value Problems, 2017 In this paper, we introduce and study a class of new Picard-Mann iterative methods with mixed errors for common fixed points of two different nonexpansive and contraction operators.

Termination of Picard Iteration for Coupled Neutronics/Thermal-Hydraulics Simulations
, 2023 In this paper, we consider the coupled N/TH problem, in which the termination criterion for the neutronics iteration adopts an adaptive tolerance with respect to the fuel temperature residual at each Picard iteration.

A fixed point theorem involving rational expressions without using Picard iteration
Topological Algebra and its Applications, 2021 In this paper, we consider a certain fixed point theorem that contains some rational expressions. The main aim of this paper is to prove a fixed point theorem without using the Picard iteration.

Advanced Science, EarlyView.Sepsis disrupts immune‐cell rhythms and weakens bacterial clearance. Biomimetic nanovesicles combining erythrocyte and inflammation‐activated macrophage membranes deliver siNR1D1 to dysfunctional macrophages, restoring the NR1D1–IGF2BP2–V‐ATPase pathway, circadian regulation, phagolysosomal acidification, and antimicrobial defense.

A pangenome-based approach reveals genes associated with polyploidy and apomixis in Eragrostis curvula. [PDF]
Plant GenomeAbstract Eragrostis curvula is a forage grass species in which multiple cytotypes coexist and shifts between sexual and apomictic reproduction are common. This study investigates genetic variation among these cytotypes in relation to ploidy levels and reproductive modes.
