Background – Grass leaf has been suspected to cause immunoglobulin (Ig)E‐mediated immediate hypersensitivity reactions both in humans and in dogs. However, most studies in this area are case control studies without in vitro data showing the involvement of IgE in the reaction.

A modified Post Widder operators preserving eᴬˣ [PDF]
In the present paper, we discuss the approximation properties of modified Post-Widder operators, which preserve the test function eᴬˣ. We establish weighted approximation and a direct quantitative estimate for the modified operators.

A new class of Bernstein-type operators obtained by iteration [PDF]
A new class of Bernstein-type operators are obtained by applying an iterative method of modifications starting from the Bernstein operators. These operators have good properties of approximation of functions and of their derivatives.

Strong inequalities for the iterated Boolean sums of Bernstein operators: Dedicated to Professor Heiner Gonska on the occasion of his 70th anniversary. [PDF]
In this paper we investigate the approximation properties for the iterated Boolean sums of Bernstein operators. The approximation behaviour of those operators is presented by the so-called strong inequalities. Moreover, such strong inequalities are valid

Global approximation properties of modified SMK operators [PDF]
In this paper, introducing a general modification of the classical Sz?sz-Mirakjan-Kantorovich (SMK) operators, we study their global approximation behavior. Some special cases are also presented. 2010 Mathematics Subject Classifications. 41A25, 41A36. .

Approximation by max-product operators of Kantorovich type: Dedicated to Professor Heiner Gonska on the occasion of his 70th anniversary. [PDF]
We associate to various linear Kantorovich type approximation operators, nonlinear max-product operators for which we obtain quantitative approximation results in the uniform norm, shape preserving properties and localization results. Mathematics Subject

Constrained visualisation using Shepard-Bernoulli interpolation operator [PDF]
We consider Shepard-Bernoulli operator in order to solve a problem of interpolation of scattered data that is constrained to preserve positivity, using the technique described by K.W. Brodlie, M.R. Asim and K. Unsworth (2005). We also give some numerical

Modified Kantorovich-Stancu operators (II) [PDF]
In this paper, we introduce a new kind of Bernstein-Kantorovich- Stancu operators. These operators generalize the operators introduced in the paper [2] by V. Gupta, G. Tachev and A.M. Acu.

On dilation operators and sampling numbers
We consider the dilation operators Tk : f → f(2k.) in the frame of Besov spaces Bpqs(ℝd) with 1 ≤p, q ≤ ∞. If s > 0, Tk is a bounded linear operator from Bpqs(ℝd) into itself and there are optimal bounds for its norm, see [4, 2.3.1]. We study the situation in the case s = 0, an open problem mentioned also in [4]. It turns out, that new effects based on
