Fuzzy stability of multi-additive mappings

Demonstratio Mathematica
The main aim of this study is to establish some stability results concerning the multi-additive mappings by applying the so-called direct (Hyers) method and the alternative fixed approach in the setting of fuzzy normed spaces.

Stability and Hyperstability of Ternary Hom-Multiplier on Ternary Banach Algebra

Axioms
In this article, we investigate the 3D additive-type functional equation. Next, we introduce the ternary hom-multiplier in ternary Banach algebras using the concepts of ternary homomorphisms and ternary multipliers.

Hyers–Ulam–Rassias Stability of Additive Mappings in Fuzzy Normed Spaces

Journal of Mathematics, 2021
In this paper, the Hyers–Ulam–Rassias stabilities of two functional equations, fax+by=rfx+sfy and fx+y+z=2fx+y/2+fz, are investigated in the framework of fuzzy normed spaces.

Increased Risk of Sarcomas in Children With Congenital Anomalies: Findings From the Genetic Overlap Between Anomalies and Cancer in Kids (GOBACK) Registry Linkage Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated. Procedure We

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

The system of mixed type additive-quadratic equations and approximations

Journal of Inequalities and Applications
In this article, we study the structure of a multiple variable mapping. Indeed, we reduce the system of several mixed additive-quadratic equations defining a multivariable mapping to obtain a single functional equation, say, the multimixed additive ...

Approximate Quadratic-Additive Mappings in Fuzzy Normed Spaces

Discrete Dynamics in Nature and Society, 2014
We examine the generalized Hyers-Ulam stability of the following functional equation: 2fx+y+z+w+f-x-y+z+w+f-x+y-z+w+f-x+y+z-w+fx-y-z+w+fx-y+z-w+fx+y-z-w-5fx-3f-x-5fy-3f-y-5fz-3f-z-5fw-3f-w=0, in the fuzzy normed spaces with the fixed point method.

Infection Control Practices for Vascular Access Management in Hemodialysis: Results From a Nationwide Survey of Japanese National University Hospitals

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Bloodstream infections due to repeated vascular access (VA) puncture and circuit connections remain major concerns in hemodialysis. Therefore, we examined current practices for glove, disinfectant, and personal protective equipment (PPE) use according to VA type in national university hospitals in Japan.

Identity related to additive mappings on standard operator algebras

Journal of Taibah University for Science, 2017
Let X be a real or complex Banach space, let L(X) be the algebra of all bounded linear operators of X and let A(X)⊆L(X) be a standard operator algebra. Suppose there exists a linear mapping T:A(X)→L(X) satisfying the relation T(An) = T(A)An−1 − AT(An−2)A
