The equivalence between T-stabilities of Krasnoselskij and Ishikawa iterations

open access: yesJournal of Numerical Analysis and Approximation Theory, 2008
We prove the equivalence between the \(T\)-stabilities of Krasnoselskij and Ishikawa iterations; a consequence is the equivalence with the \(T\)-stability of Picard-Banach iteration.

Some Convergence Theorems for Contractive Type Mappings in CAT(0) Spaces

open access: yesAbstract and Applied Analysis, 2013
We establish theorems of strong convergence, for the Ishikawa-type (or two step; cf. Ishikawa, 1974) iteration scheme, to a fixed point of a uniformly L-Lipschitzian asymptotically demicontractive mapping and a uniformly L-Lipschitzian hemicontractive ...

A Bayesian approach to spectroscopic depth sectioning for locating dopant atoms

open access: yesJournal of Microscopy, EarlyView.
Abstract Locating dopants in 3D is of great interest as advanced materials and devices increasingly rely on control at atomic dimensions, and microscopy tools are constantly in development for this purpose. One potential tool is electron energy loss spectroscopy (EELS) depth sectioning, where a core‐loss signal is collected as a function of electron ...

The necessary and sufficient condition for the convergence of Ishikawa iteration on an arbitrary interval

open access: yes, 2006
As an important iteration, the Mann and Ishikawa iteration has extensive application in fixed point theory. In 1991, David Borwein and Jonathan Borwein proved the convergence of the Mann iteration on a closed bounded interval in their paper.

FvMAPK6‐Mediated FvMYB44s/FvSWEET1 Dual‐Layer Regulation Modulates Sugar Accumulation in Strawberry Fruit, With FvSPS3 Enabling Quality–Yield Balance

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Sugar content is a key determinant of fruit quality, and sugars also act as signalling molecules that regulate ripening processes, including anthocyanin accumulation. However, the molecular mechanisms underlying sugar accumulation and sugar signal‐mediated ripening remain incompletely understood.

An iteration process for common fixed points of two nonself asymptotically nonexpansive mappings

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
In this paper, we introduce an iteration process for approximating common fixed points of two nonself asymptotically nonexpansive map- pings in Banach spaces.

A note on the Ishikawa iteration scheme

open access: yesJournal of Mathematical Analysis and Applications, 1992
This article deals with the convergence of the sequence \(x_ n\) that is defined by the following iterative procedure \[ x_ 0\in C, \quad y_ n\in c_ 0\{\{x_ i\}^ n_{i=0} \bigcup \{Tx_ i\}^ n_{i=0}\}, \quad x_{n+1}=(1-\alpha_ n)x_ n+\alpha_ n Ty_ n \] for a mapping \(T: C\to C\) on a nonempty closed convex subset \(C\) of a Banach space \(X\). Here \(T\)

A quality improvement initiative to reduce inappropriate plasma transfusions across community hospitals in the Niagara region

open access: yesVox Sanguinis, EarlyView.
Abstract Background and Objectives Plasma transfusion is indicated for patients with coagulopathy and active bleeding or those undergoing major surgery. Appropriate use is defined by an international normalized ratio (INR) >1.7 and a dose of 3–4 units for adults.
