Can Servitization Strategy Improve Corporate Environmental, Social, and Governance (ESG) Performance? Empirical Evidence From Listed Manufacturing Enterprises in China

Discrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.
At present, utilizing servitization to enhance the ESG performance of manufacturing enterprises is an important strategic path for achieving carbon reduction and sustainable development in the manufacturing industry. Using ordinary least squares (OLS) regression and a sample of A‐share listed manufacturing companies from 2010 to 2022, this paper ...

The atmospherical drought as a decisive factor of yield in the main sour cherry varieties of Hungary [PDF]

, 2012
Atmospheric drought causes heavy diffi culties of water supply in most fruit species grown in Hungary, although the modern, intensive plantations are already equipped with irrigation.

The Adaptive Backstepping Synchronization Control for a Kind of Variable-Order Fractional Uncertain Nonlinear Systems

Fractal and Fractional
This paper is concerned with the adaptive backstepping synchronization control for a class of variable-order (VO) fractional uncertain nonlinear system with external disturbances and a dead zone. A kind of VO fractional command filter is employed to cope

Approximation results on Dunkl generalization of Phillips operators via q-calculus

Advances in Difference Equations, 2019
The main purpose of this paper is to construct q-Phillips operators generated by Dunkl generalization. We prove several results of Korovkin type and estimate the order of convergence in terms of several moduli of continuity.

The Zero Product of Toeplitz Operators on the 2‐Analytic Weighted Bergman Space

Journal of Function Spaces, Volume 2025, Issue 1, 2025.
Two‐analytic weighted Bergman space is a nonanalytic function space which is closely related to analytic functions. In this paper, we mainly discuss the zero product problem for Toeplitz operators on the 2‐analytic weighted Bergman space.

Real-time density-matrix coupled-cluster approach for closed and open systems at finite temperature [PDF]

, 2019
We extend the coupled-cluster method to correlated quantum dynamics of both closed and open systems at finite temperatures using the thermofield formalism.

Weighted Approximation by Szász–Mirakyan–Durrmeyer Operators Reproducing Exponential Functions

Mathematics
We examine a Szász–Mirakyan–Durrmeyer type operator that reproduces the functions 1 and e2ax for a fixed parameter a>0. While its exponential reproduction property has been described in the classical literature, the effect of exponential weights on its ...

Statistical convergence of integral form of modified Szász–Mirakyan operators: an algorithm and an approach for possible applications

Journal of Inequalities and Applications
In this study, we take into account the of modified Szász–Mirakyan–Kantorovich operators to obtain their rate of convergence using the modulus of continuity and for the functions in Lipschitz space.
