Approximation Properties of Certain Summation Integral Type Operators
Demonstratio Mathematica, 2015 In the present paper, we study approximation properties of a family of linear positive operators and establish direct results, asymptotic formula, rate of convergence, weighted approximation theorem, inverse theorem and better approximation for this ...

Rapid near-optimal VQ design with a deterministic data net [PDF]
, 2005 We present a new algorithm for fixed-rate vector quantizer (VQ) design with deterministic data net. The algorithm also performs efficient VQ design for simply characterized continuous distributions. The algorithm also serves as an approximation algorithm

The Thin-Wall Approximation in Vacuum Decay: a Lemma
, 2018 The 'thin-wall approximation' gives a simple estimate of the decay rate of an unstable quantum field. Unfortunately, the approximation is uncontrolled.

On the convergence rates of Legendre approximation [PDF]
Mathematics of Computation, 2011 Expansions of suitable univariate functions in infinite or truncated series of Legendre polynomials are considered in this article. Under analyticity conditions or conditions on the continuity of the approximand and its derivatives, upper bounds on the coefficients in these series are established.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

On the rate of convergence of Baskakov-Kantorovich-Bézier operators for bounded variation functions
Journal of Numerical Analysis and Approximation Theory, 2002 In the present paper we introduce Baskakov-Kantorovich-Bézier operators and study their rate of convergence for functions of bounded variation.

Approximation by (p,q) $(p,q)$-Lupaş–Schurer–Kantorovich operators
Journal of Inequalities and Applications, 2018 In the current paper, we examine the (p,q) $(p,q)$-analogue of Kantorovich type Lupaş–Schurer operators with the help of (p,q) $(p,q)$-Jackson integral.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

European Journal of Pharmaceutical Sciences, 2017 The influence of drug‐target binding kinetics on target occupancy can be influenced by drug distribution and diffusion around the target, often referred to as “rebinding” or “diffusion‐limited binding”.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
