Interpolated scales of approximation spaces for regular elliptic operators on compact manifolds

Karpatsʹkì Matematičnì Publìkacìï, 2014
We define the interpolated scales of approximation spaces, generated by regular elliptic operators on compact manifolds. The appropriate Bernstein-Jackson inequalities and application to spectral approximations of regular elliptic operators are ...

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 ...

Improving approximation via linear combinations of Bernstein operators

Journal of Numerical Analysis and Approximation Theory
In this paper, a new way to improve approximation operators is proposed. Two well-known methods are combined: the linear combination of the classic Bernstein operator and the iteration technique.

A Bernstein-type operator approximating continuous functions on the semi-axis [PDF]

, 1980
The authors present a Bernstein-type operator Ln which is given by a finite sum and defined on the space C(0,∞). It is shown that Ln defines a positive linear operator such that Lnf(x) tends pointwise on [0, ∞) to f(x) for n → ∞.

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 ...

A note on a Bernstein-type operator of Bleimann, Butzer, and Hahn [PDF]

, 1988
Let Ln(f, x)(f ϵ C)[0, ∞)) be a Bernstein-type approximation operator as defined and studied by Bleimann, Butzer, and Hahn. Probabilistic arguments are used to simplify and sharpen some of their results. The rates of convergence are given in terms of the

Unraveling the Interplay Between Collaborative Governance and Experimentation for Transformative Potential in Circular Water Systems: A Dutch Case Study

Environmental Policy and Governance, EarlyView.
ABSTRACT Freshwater availability is a critical climate change challenge in coastal delta regions. This challenge requires a transformative change toward circular water management. While experimentation and collaborative governance are recognized as enablers of transformative change, their interaction remains complex and insufficiently understood ...

Approximation properties of (p, q)-Bernstein type operators [PDF]

Acta Universitatis Sapientiae, Mathematica, 2016
Abstract We introduce a new generalization of the q-Bernstein operators involving (p, q)-integers, and we establish some direct approximation results. Further, we define the limit (p, q)-Bernstein operator, and we obtain its estimation for the rate of convergence. Finally, we introduce the (p, q)-Kantorovich type operators, and we give a

Comparative multicenter evaluation of thalamic neuromodulation for treatment‐resistant epilepsy in children

Epilepsia, EarlyView.
Abstract Objective Use of neuromodulation strategies targeting thalamic nuclei, including deep brain stimulation (DBS) and responsive neurostimulation (RNS), for treatment of pediatric drug‐resistant epilepsy (DRE) is increasing, despite limited evidence for efficacy and safety. We present the initial results from the Comparative Multicenter Evaluation

Some Statistical and Direct Approximation Properties for a New Form of the Generalization of q-Bernstein Operators with the Parameter λ

Axioms
In this study, a different generalization of q-Bernstein operators with the parameter λ∈[−1,1] is created. The moments and central moments of these operators are calculated, a statistical approximation result for this new type of (λ,q)-Bernstein ...
