Approximation by Lupas-Type Operators and Szász-Mirakyan-Type Operators
Journal of Applied Mathematics, 2012 Lupas-type operators and Szász-Mirakyan-type operators are the modifications of Bernstein polynomials to infinite intervals. In this paper, we investigate the convergence of Lupas-type operators and Szász-Mirakyan-type operators on [0,∞).

Coupling Fluid Neutrals to Gyrokinetic Plasma Dynamics for Edge and SOL Turbulence Simulations
Contributions to Plasma Physics, EarlyView.ABSTRACT Accurate modeling of turbulent transport in magnetic confinement fusion devices requires extending first‐principles gyrokinetic simulations from the core to the edge and scrape‐off layer (SOL), where additional physics—particularly plasma–neutrals interactions—must be included.

On the Complexity of Optimization over the Standard Simplex [PDF]
We review complexity results for minimizing polynomials over the standard simplex and unit hypercube.In addition, we show that there exists a polynomial time approximation scheme (PTAS) for minimizing Lipschitz continuous functions and functions with ...

Improved Conservative Scheme for Lenard‐Bernstein Collisions in Gyrokinetic Turbulence Simulations
Contributions to Plasma Physics, EarlyView.ABSTRACT Turbulence in the edge and scrape‐off layer regions plays a critical role for the performance of future magnetic confinement fusion power plants. Gyrokinetic simulations allow studying this regime with high fidelity. A key aspect in these regions is the high concentration of impurities, which can radiate energy, leading to significant losses ...

On Sequences of J. P. King-Type Operators
Journal of Function Spaces, 2019 This survey is devoted to a series of investigations developed in the last fifteen years, starting from the introduction of a sequence of positive linear operators which modify the classical Bernstein operators in order to reproduce constant functions ...

Derivatives of multidimensional Bernstein operators and smoothness [PDF]
, 2005 We characterize the directional derivatives of multidimensional Bernstein operators by a new measure of smoothness. This task is carried out by means of establishing the relation between the asymptotic behavior of the derivatives and the smoothness of ...

On the eigenstructure of the modified bernstein operators
, 2022 Starting from the well-known work of Cooper and Waldron published in 2000, the eigenstructure of various Bernstein-type operators has been investigated by many researchers.

Thresholds: The metaphorical foundations of powerful knowledge
The Curriculum Journal, EarlyView.Abstract This paper advances a theoretical account of threshold concepts as metaphorical‐relational structures that reorganise meaning across contexts. Building on conceptual metaphor theory, we propose that threshold concepts can be understood as sites of schema‐level reorganisation: deep, embodied patterns of relational logic that scaffold abstract ...
