An Extragradient Method for Mixed Equilibrium Problems and Fixed Point Problems [PDF]

Fixed Point Theory and Applications, 2009
AbstractThe purpose of this paper is to investigate the problem of approximating a common element of the set of fixed points of a demicontractive mapping and the set of solutions of a mixed equilibrium problem. First, we propose an extragradient method for solving the mixed equilibrium problems and the fixed point problems.

Impact of Japan's 2024 Physician Work‐Style Reform on Pediatric Hematology–Oncology: Educational Implications in a 2‐Year Survey

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Japan's 2024 physician work‐style reform introduced legally binding limits on physicians’ working hours, but its impact on education and workforce sustainability in pediatric hematology–oncology (PHO) remains unclear. Procedure We conducted a repeated cross‐sectional study with structured quantitative items and free‐text responses ...

The plane fixed point problem

, 2008
In this paper we present proofs of basic results, including those developed so far by H. Bell, for the plane fixed point problem. Some of these results had been announced much earlier by Bell but without accessible proofs. We define the concept of the variation of a map on a simple closed curve and relate it to the index of the map on that curve: Index

On solutions of inclusion problems and fixed point problems [PDF]

Fixed Point Theory and Applications, 2013
The paper proposes an iterative algorithm for the solution of the following problem: \[ x= S(x) \text{ and } x\in (A+B)^{-1}(0), \] where \(S:C\to C\) is a mapping and \(A,B:C\to H\) are two monotone mappings on a nonempty, closed, convex subset \(C\) of an Hilbert space \(H\).

An Extragradient Method for Fixed Point Problems and Variational Inequality Problems [PDF]

Journal of Inequalities and Applications, 2007
An extragradient method is presented for the fixed point problems and variational inequality problems. A common element of the set of fixed points of a nonexpansive mapping and the set of solutions of the variational inequality for a monotone mapping is found using the considered method.

Association Between Individualized Education for Kidney Replacement Therapy Modality Selection and Peritoneal Dialysis Initiation: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) is an established home‐based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Discussion on the fixed point problems with constraint inequalities

Journal of Inequalities and Applications, 2018
In this paper, we introduce the concept of comparable complete metric spaces and consider some fixed point theorems for mappings in the setting of incomplete metric spaces. We obtain the results of Ansari et al. [J. Fixed Point Theory Appl. 20:26, 2018] with weaker conditions. Moreover, we provide some corollaries and examples show that our main result

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Double solutions of three-point boundary-value problems for second-order differential equations

Electronic Journal of Differential Equations, 2004
A double fixed point theorem is applied to yield the existence of at least two nonnegative solutions for the three-point boundary-value problem for a second-order differential equation, $$displaylines{ y'' + f(y)=0,quad 0 leq t leq 1,cr y(0) =0,quad y(p)
