Approximation properties by Schurer type q-Kantorovich–Stancu shifted knots operators

open access: yesJournal of Inequalities and Applications
We design the Schurer type Kantorovich–Stancu operators by using shifted knots in the quantum calculus. We obtain the convergence and other related approximation properties of these operators.

The theory of pure operations

open access: yesCommunications in Mathematical Physics, 1972
This paper continues the study started in [13] where classes of operations were investigated in the partially ordered vector space approach to the theory of statistical physical systems. In this approach the set of states is represented by a norm closed generating coneK in a complete base norm space (V, K, B) and the set of operations is represented by

The Paulsen Problem in operator theory [PDF]

open access: yesOperators and Matrices, 2013
The Paulsen Problem in Hilbert space frame theory has proved to be one of the most intractable problems in the field. We will help explain why by showing that this problem is equivalent to a fundamental, deep problem in operator theory. Along the way we will give a new exact computation for chordal distances, we will give a generalization of these ...

Operator Algebra in Logarithmic Conformal Field Theory

open access: yes, 2005
For some time now, conformal field theories in two dimensions have been studied as integrable systems. Much of the success of these studies is related to the existence of an operator algebra of the theory.

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Approximation by Schurer Type λ-Bernstein–Bézier Basis Function Enhanced by Shifted Knots Properties

open access: yesMathematics
In this article, a novel Schurer form of λ-Bernstein operators augmented by Bézier basis functions is presented by utilizing the features of shifted knots.

Generalized ( p , q ) $(p,q)$ -Bleimann-Butzer-Hahn operators and some approximation results

open access: yesJournal of Inequalities and Applications, 2017
The aim of this paper is to introduce a new generalization of Bleimann-Butzer-Hahn operators by using ( p , q ) $(p,q)$ -integers which is based on a continuously differentiable function μ on [ 0 , ∞ ) = R + $[0,\infty)=\mathbb{R}_{+}$ . We establish the

Arithmetic theory of $E$-operators [PDF]

open access: yesJournal de l’École polytechnique — Mathématiques, 2016
In [S ries Gevrey de type arithm tique I Th or mes de puret et de dualit , Annals of Math. 151 (2000), 705--740], Andr has introduced E-operators, a class of differential operators intimately related to E-functions, and constructed local bases of solutions for these operators.

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

open access: yesMolecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.

Order theory and interpolation in operator algebras

open access: yes, 2014
We continue our study of operator algebras with and contractive approximate identities (cais). In earlier papers we have introduced and studied a new notion of positivity in operator algebras, with an eye to extending certain C*-algebraic results and ...
