In Functional Data Analysis (FDA), the existing summary statistics so far are elements in Hilbert space L2 of square-integrable functions. These do not constitute an ordered set; therefore, they sufficient to solve problems related comparability such as obtaining a correlation measurement or comparing variability between two sets curves, determining efficiency and consistency functional estimat...

Abstract The Scuttle fly, Eurygaster integriceps Puton (Hemiptera: Scutelleridae) is a key pest of wheat and barley. univoltine migrates from fields following harvest to high elevations; then, the spring it moves back fields. Natural enemies may have an important role in decreasing population’s level overwintering sites. In present study, adults E. were collected sites Isfahan province, Iran, O...

Abstract Background The phorid fly Megaselia scalaris (Loew) (Diptera: Phoridae) is an omnivorous species, capable of exploring a large variety environments and ecological niches. It known as important detritivore species with maggots feeding on food both animal plant origin. Results present study reports M. endoparasitoid attacking colonies the southern green stink bug Nezara viridula (L.) for...

we prove that every r-quadratic metric of scalar flag curvature with a dimension greater than twois of constant flag curvature. then we show that generalized douglas-weyl metrics contain r-quadraticmetrics as a special case, but the class of r-quadratic metric is not closed under projective transformations
