Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(

Assessing Climate Change Disclosure and Its Governance Drivers: Insights From the European Utilities Sector

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study aims to enhance academic understanding of the factors influencing the disclosure practices of climate change among European utility companies, specifically in the context of their sustainability reporting. The primary objective is to explore, through a multi‐theoretical framework, the governance drivers that significantly affect the

Existence and Asymptotic Estimates of the Maximal and Minimal Solutions for a Coupled Tempered Fractional Differential System with Different Orders

open access: yesAxioms
In this paper, we focus on the existence and asymptotic estimates of the maximal and minimal solutions for a coupled tempered fractional differential system with different orders. By introducing an order reduction technique and some new growth conditions,

What Drives CSR Performance: Structures, Declarations or Values?

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainability and corporate social responsibility (CSR) are increasingly central to strategic management, yet a gap persists between formal commitments and actual practice. The study explores the structural and value‐based predictors of the institutional integration of CSR and sustainability, with a focus on the mediating role of the CSR ...

Adapting to Water Scarcity in Mediterranean Greenhouse Agriculture: Insights From Digital Irrigation and Regulated Water Governance in Southeastern Spain

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Climate‐driven water scarcity is compounding adaptation pressures on Mediterranean greenhouse farming, particularly for small and micro agricultural firms governed by regulated water‐governance systems. This paper analyses differentiated adaptation profiles in Almería (Spain) based on an analysis of farm structure, digital irrigation adoption,

Asymptotic Formula for the Moments of the Takagi Function

open access: yesAutomatic Control and Computer Sciences, 2017
The Takagi function is a simple example of a continuous yet nowhere differentiable function and is given as T(x) = Σk=0∞ 2−n ρ(2 n x), where \(\rho (x) = \mathop {\min }\limits_{k \in \mathbb{Z}} |x - k|\). The moments of the Takagi function are given as M n = ∫01x n T(x)dx. The estimate \({M_n} = \frac{{1nn - \Gamma '(1) - 1n\pi }}{{{n^2}1n2}} + \frac{

On the Design of a Class of Analog Filters Whose Impulse Response Is a Mittag‐Leffler Function

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
Fractional‐order filters whose impulse response is a Mittag‐Leffler (M‐L) function in any of its known forms are summarized in this work. Simulation results using Cadence and experimental results using an FPAA validate the introduced concept. ABSTRACT Fractional‐order filters whose impulse response is a Mittag‐Leffler (M‐L) function in any of its known

Generalized Chemical Model for Warm Dense Hydrogen: Ionization Potential Depression and Molecular Dissociation Shifts

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Warm dense matter (WDM) is a complex state, where quantum effects, thermal excitations, and strong interparticle correlations coexist. Understanding its microscopic composition and medium‐induced modifications of atomic and molecular properties is essential for planetary modeling, fusion research, and high‐energy‐density experiments.
