Quasi-linear dynamics of Weibel instability [PDF]
Annales Geophysicae, 2011 The quasi-linear dynamics of resonant Weibel mode is discussed. It is found that nonlinear saturation of Weibel mode is accompanied by substantial modification of the distribution function in resonant region.

Semi-Parametric Estimation Using Bernstein Polynomial and a Finite Gaussian Mixture Model
Entropy, 2022 The central focus of this paper is upon the alleviation of the boundary problem when the probability density function has a bounded support. Mixtures of beta densities have led to different methods of density estimation for data assumed to have compact ...

ON A BERNSTEIN–SATO POLYNOMIAL OF A MEROMORPHIC FUNCTION
Nagoya Mathematical Journal, 2023 AbstractWe define Bernstein–Sato polynomials for meromorphic functions and study their basic properties. In particular, we prove a Kashiwara–Malgrange-type theorem on their geometric monodromies, which would also be useful in relation with the monodromy conjecture. A new feature in the meromorphic setting is that we have several b-functions whose roots

Approximation properties of bivariate complex $q$-Bernstein polynomials in the case $q>1$ [PDF]
, 2012 summary:In the paper, we discuss convergence properties and Voronovskaja type theorem for bivariate $q$-Bernstein polynomials for a function analytic in the polydisc $D_{R_{1}}\times D_{R_{2}}=\{z\in C\colon \vert z\vert 1$.

Arab Journal of Mathematical Sciences, 2019 We give several new characterizations of completely monotone functions and Bernstein functions via two approaches: the first one is driven algebraically via elementary preserving mappings and the second one is developed in terms of the behavior of their ...

q-Bernstein polynomials and Bézier curves [PDF]
, 2003 We define q-Bernstein polynomials, which generalize the classical Bernstein polynomials, and show that the difference of two consecutive q-Bernstein polynomials of a function f can be expressed in terms of second-order divided differences of f.

Abstract and Applied Analysis, 2014 This paper is concerned with approximation on variable Lρp(·) spaces associated with a general exponent function p and a general bounded Borel measure ρ on an open subset Ω of Rd. We mainly consider approximation by Bernstein type linear operators. Under

King type modification of $q$-Bernstein-Schurer operators [PDF]
, 2013 summary:Very recently the $q$-Bernstein-Schurer operators which reproduce only constant function were introduced and studied by C. V. Muraru (2011). Inspired by J. P. King, Positive linear operators which preserve $x^{2}$ (2003), in this paper we modify $
