The Kantorovich form of some extensions for the Szász-Mirakjan operators

Journal of Numerical Analysis and Approximation Theory, 2010
Recently, C. Mortici defined a class of linear and positive operators depending on a certain function \(\varphi\). These operators generalize the well known Szász-Mirakjan operators.

Kantorovich-Stancu type (α,λ,s) - Bernstein operators and their approximation properties

Mathematical and Computer Modelling of Dynamical Systems
In this study, we establish a new class of Kantorovich-Stancu type $\left({\alpha ,\lambda ,s} \right) - $α,λ,s−Bernstein operators via an adaptation of Bézier bases which are formulated with the inclusion of the shape parameters $\lambda \in \left[{ - 1,

MagmaFlow: A desktop platform for artificial intelligence‐driven expression analysis

FEBS Open Bio, EarlyView.
MagmaFlow is a free, no‐code platform for gene expression analysis. It generates interactive volcano plots, links genes to literature, pathways, and diseases, prioritizes candidates using millions of publications, identifies affected biological processes, builds network diagrams, and exports publication‐ready figures and reports for macOS and Windows ...

Approximation theorems for positive operators on Lp-spaces [PDF]

, 1990
Let 1 < r ⩽ p < ∞. Approximation theorems for positive contractions in L(Lp(m), Lr(n)) are presented. The characterization of norm attaining extreme positive contractions is given. Note that these extreme operators are also exposed points of the positive

Analysis of Approximation by Linear Operators on Variable Lρp(·) Spaces and Applications in Learning Theory

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

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

FEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Korovkin-type convergence results for multivariate Shepard formulae

Journal of Numerical Analysis and Approximation Theory, 2009
We present a new convergence proof for classic multivariate Shepard formulae within the context of Korovkin-type convergence results for positive operators on spaces of continuous real valued functions.

Statistical approximation by double sequences of positive linear operators on modular spaces

, 2015
In this paper, using the concept of statistical convergence, which is stronger than the Pringsheim convergence, we study the problem of approximation to a function by means of double sequences of positive linear operators defined on a modular space. Also,

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.
