The Kantorovich form of some extensions for the Szász-Mirakjan operators

Journal of Numerical Analysis and Approximation Theory, 2010
Recently, C. Mortici defined a class of linear and positive operators depending on a certain function \(\varphi\). These operators generalize the well known Szász-Mirakjan operators.

Approximation by Szász-Jakimovski-Leviatan-Type Operators via Aid of Appell Polynomials

Journal of Function Spaces, 2020
The main purpose of the present article is to construct a newly Szász-Jakimovski-Leviatan-type positive linear operators in the Dunkl analogue by the aid of Appell polynomials.

Bayesian clustering of multivariate extremes

Canadian Journal of Statistics, EarlyView.
Abstract The asymptotic dependence structure between multivariate extreme values is fully characterized by their projections on the unit simplex. Under mild conditions, the only constraint on the resulting distributions is that their marginal means must be equal, which results in a nonparametric model that can be difficult to use in applications ...

Quantitative estimates for bivariate Stancu operators

Mathematical Methods in the Applied Sciences, 2018
In this paper, we introduce Voronovskaja‐type and Grüss–Voronovskaja‐ type theorems in quantitative mean with the help of the usual modulus of continuity for bivariate Stancu operators, which are different from a tensor product setting.

Patterns and Drivers of Spanish Corporate Commitment to the UN Global Compact: A Quantitative Approach

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This paper presents a quantitative assessment of Spanish companies' commitment to the United Nations Global Compact (UNGC) and the Sustainable Development Goals (SDGs). Analyzing over 1000 participating firms, we identify prioritization patterns and examine structural factors influencing SDG adherence.

Co-operational bivariant theory

Mathematics Research Reports
For a covariant functor W. Fulton and R. MacPherson defined an operational bivariant theory associated to this covariant functor. In this paper we will show that given a contravariant functor one can similarly construct a “dual” version of an operational bivariant theory, which we call a co-operational bivariant theory. If a given contravariant functor

The difficult discussion on the deactivation of implantable cardioverter devices at the end of life: a systematic review

ESC Heart Failure, Volume 12, Issue 2, Page 733-760, April 2025.
Abstract Implantable cardioverter defibrillators (ICDs) reliably prevent death due to life‐threatening arrhythmias; this may become less relevant in people with more severe heart failure who are reaching the end of life (EOL). This review aimed to explore the ICD deactivation process and identify ethical issues, especially around the initiation of ...

Structure of wavefunctions in (1+2)-body random matrix ensembles

, 2001
Abstrtact: Random matrix ensembles defined by a mean-field one-body plus a chaos generating random two-body interaction (called embedded ensembles of (1+2)-body interactions) predict for wavefunctions, in the chaotic domain, an essentially one parameter ...

Partial shape preserving approximations by bivariate shepard operators

Computers & Mathematics with Applications, 2001
The authors prove that the bivariate Shepard interpolation operators preserve the monotonicity and the convexity of bivariate functions in neighbourhoods of certain points. This extends results for the univariate case obtained by \textit{S. G. Gal} and \textit{J. Szabados} [Partial shape preserving approximation by interpolation operators, in functions,

The Impact of Freedom of Speech on Conspiracy Beliefs

European Journal of Social Psychology, EarlyView.
ABSTRACT Conspiracy beliefs are often portrayed as a threat to democracies. However, less is known about the extent to which the state of democracy may affect conspiracy beliefs. Hence, we investigated the impact of the societal level of freedom of speech on conspiracy beliefs. In Study 1, using aggregated nation‐level data (N = 68 countries), we found
