In this talk we discuss some aspects of the analytical calculation of energy correlations in electronpositron annihilation at a next-to-leading order in QCD. Our primary focus is on the most difficult task: the calculation of master integrals for real-emission contributions, which are functions of two dimensionless variables and the dimensional regulator. We use a method of differential equatio...

This paper discusses operators lowering or raising the degree but preserving the parameters of special orthogonal polynomials. Results for onevariable classical (q-)orthogonal polynomials are surveyed. For Jacobi polynomials associated with root system BC2 a new pair of lowering and raising operators is obtained.

Fraud is a global problem that has required more attention due to an accentuated expansion of modern technology and communication. When statistical techniques are used to detect fraud, whether a fraud detection model is accurate enough in order to provide correct classification of the case as a fraudulent or legitimate is a critical factor. In this context, the concept of bootstrap aggregating ...

Predictions about information search behavior have been informed by extensive research in food foraging behavior. However, information foraging environments may differ in key ways from food foraging environments, and these differences may impact search behavior. We investigated the effect of patch distribution (depleting or non-depleting) and ability to return to previously searched patches on ...

Abstract—Soil samples were collected from and around Alkomos cement factory, Alkomos town, Libya. Soil physiochemical properties were determined. In addition, olive leaves were scanned for their fungal content. This work can conclude that the results obtained for the examined physiochemical characteristics of soil in the area studied prove that cement dust from the Alkomos cement factory in Lib...

Facing the pressure on the transportation market, freight carriers are suggested to exchange customer requests through collaborative transport planning for further increment of their profitability. This paper discusses the chances offered by this kind of horizontal collaboration and proposes challenges to meet its successful utilization. Keyword: horizontal collaboration, request exchange, prof...

Abstract: Lüders’ theorem states that two observables commute if measuring one of them does not disturb the measurement outcomes of the other. We study measurements which are described by continuous positive operatorvalued measurements (or POVMs) associated with coherent states on a Lie group. In general, operators turn out to be invariant under the Lüders map if their P and Q-symbols coincide....

In this paper, we consider weighted composition operators betweenmeasurable differential forms and then some classic properties of these operators are characterized.

in this paper, we improve some recent coupled fixed point resultsfor single-valued operators in the framework of ordered $b$-metricspaces established by bota et al. [m-f. bota, a. petrusel, g.petrusel and b. samet, coupled fixed point theorems forsingle-valued operators in b-metric spaces, fixed point theoryappl. (2015) 2015:231]. also, we prove that perov-type fixed pointtheorem in ordered gen...
