An alternative Jensen's functional equation on semigroups [PDF]
ScienceAsia, 2012 We study the alternative Jensen's functional equation f(x) 2f(xy) + f(xy 2 ) = 0 when f is a ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study examines the impact of board composition (BC) on sustainability reporting (SR) in financial firms listed on the Dhaka Stock Exchange (DSE), with a focus on the moderating role of non‐performing loans (NPLs). Using 421 firm‐year observations from 49 firms (2016–2024) and an ordinary least squares (OLS) regression model, the results ...

Hyperstability of Cauchy and Jensen functional equations in 2-normed spaces
Journal of Inequalities and ApplicationsIn this article, with simple and short proofs without applying fixed point theorems, some hyperstability results corresponding to the functional equations of Cauchy and Jensen are presented in 2-normed spaces.

Stability of the Jensen-Type Functional Equation in C∗-Algebras: A Fixed Point Approach
Abstract and Applied Analysis, 2009 Using fixed point methods, we prove the generalized Hyers-Ulam stability of homomorphisms in C∗-algebras and Lie C∗-algebras and also of derivations on C∗-algebras and Lie C∗-algebras for the Jensen-type functional equation f((x+y)/2)+f((x−y)/2)=f(x).

Honeycomb lattice polygons and walks as a test of series analysis techniques
, 2005 We have calculated long series expansions for self-avoiding walks and polygons on the honeycomb lattice, including series for metric properties such as mean-squared radius of gyration as well as series for moments of the area-distribution for polygons ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT The purpose of this study is to examine the relationship between board composition characteristics and ESG performance in companies from BRICS countries, and to assess how sector sensitivity moderates this relationship. A sample of 2045 BRICS companies was examined using panel data regression with random effects and logistic regression ...

On thermal fluctuations and the generating functional in relativistic hydrodynamics
, 2015 We discuss a real-time generating functional for correlation functions in dissipative relativistic hydrodynamics which takes into account thermal fluctuations of the hydrodynamic variables.

Plasma Activate Nitrogen for Efficient Ammonia Synthesis
Exploration, EarlyView.This review systematically summarizes the classification and reaction mechanism of plasma, and discusses the synergy between different plasmas and catalytic methods along with energy consumptions in detail, in order to gain a deeper understanding of currently ammonia synthesis strategies.

Coupling of Surface and Volume Dipole Oscillations in C-60 Molecules
, 2007 We first give a short review of the ``local-current approximation'' (LCA), derived from a general variation principle, which serves as a semiclassical description of strongly collective excitations in finite fermion systems starting from their quantum ...

Food Chemistry International, EarlyView.After collecting Musa paradisiaca leaves, some were dried and others were used to produce aqueous extracts. The extracts and powders were characterized and then administered to rats made anaemic by PHZ. After 14 days of administration of the two samples, the rats were euthanized and it was observed that after 9 days of treatment, the aqueous extract ...
