An approximate solution of the Blasius problem using spectral method

open access: yesPartial Differential Equations in Applied Mathematics
This paper aims at finding the numerical approximation of a classical Blasius flat plate problem using spectral collocation method. This technique is based on Chebyshev pseudospectral approach that involves the solution is approximated using Chebyshev ...

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

open access: yesAdvanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Modified Bernstein Polynomials and Jacobi Polynomials in q-Calculus

open access: yes, 2004
We introduce here a generalization of the modified Bernstein polynomials for Jacobi weights using the $q$-Bernstein basis proposed by G.M. Phillips to generalize classical Bernstein Polynomials.

Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz

open access: yesAdvanced Materials, EarlyView.
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

A Kantorovich-Stancu Type Generalization of Szasz Operators including Brenke Type Polynomials

open access: yesJournal of Function Spaces and Applications, 2013
We introduce a Kantorovich-Stancu type modification of a generalization of Szasz operators defined by means of the Brenke type polynomials and obtain approximation properties of these operators.

Liquid‐in‐Liquid Prints: High‐Density Biochemically Encoded Information Preserved in Microdroplet Arrays

open access: yesAdvanced Materials, EarlyView.
This work introduces a novel approach for encoding and storing information in the liquid state in microdroplet arrays. These liquid‐in‐liquid prints are generated by a droplet printing system capable of dynamically setting the composition of each droplet pixel.

Discrete Least-norm Approximation by Nonnegative (Trigonomtric) Polynomials and Rational Functions [PDF]

open access: yes
Polynomials, trigonometric polynomials, and rational functions are widely used for the discrete approximation of functions or simulation models.Often, it is known beforehand, that the underlying unknown function has certain properties, e.g.

Approximation by incomplete polynomials

open access: yesJournal of Approximation Theory, 1980
AbstractFor any Θ with 0 < Θ < 1, it is known that the set of all incomplete polynomials of form Pn(x)=∑k=νnakxk, μ⩾φ·n is not dense in Co[a, 1]: = {fϵ C[a, 1]:f(a) = 0} if a < Θ2. In this paper, we prove that the set (1) of incomplete polynomials is dense in Co[a, 1]if a ⩾ Θ2 and even has the Jackson property on [a, 1]if a > Θ2.

Best approximation by polynomials [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2003
In this paper we show that if E is a separable Banach space, F is a reflexive Banach space, and n, k ∈ ℕ, then every continuous polynomial of degree n from E into F has at least one element of best approximation in the Banach subspace of all continuous k–homogeneous polynomials from E into F.
