Abstract In this paper, we classify the fixed and critical points of bi-parametric family Ostrowski–Chun methods applied on quadratic polynomials. We obtain values parameters that reduce number free points. select one-parametric subfamilies with only one point carry out a dynamical study these subfamilies. For each subfamily parameter plane in order to consider which numerical are more appropri...

The object of the present paper is to find essential properties for certain subfamilies analytic and spirallike functions which are generated by q-integral operator. Further, we obtained membership relations belong these subclasses, also determined coefficients estimates subfamilies.

abstract the syrphidae family with almost 6000 described species, 15 tribes and 3 subfamilies is one of the largest families of diptera. they known as hoverflies or flowerflies. the larvae of subfamily syrphinae are considered the specialized aphidophagous predators play an important role in the reduction of aphid populations in agroecosystems. almost all the adult syrphids feed on pollen or ne...

The first report on the composition of carabids from a natural forest in peninsular India as well dry belt rain shadow region Western Ghats is provided, with data subfamilies, tribes, genera, species, geographic range, collection techniques, and relevant literature details for all listed species. Fifty-four species belonging to 11 subfamilies 31 genera were recorded. Harpalinae, Lebiinae, Scari...

Chicken repeat 1 (CR1) is an interspersed repetitive element that is a member of the non-long terminal repeat class of retrotransposons. A data set of chicken 95 CR1 elements was compiled and the phylogeny of the 52 elements with the most complete 3' ends was examined. We interpret the branching pattern as clustering into at least six subfamilies, designated A-F. The presence of highly similar ...

G-protein coupled receptors (GPCRs) are a large superfamily of integral membrane proteins that transduce signals across the cell membrane. Because of that important property and other physiological roles undertaken by the GPCR family, they have been an important target of therapeutic drugs. The function of many GPCRs is not known and accurate classification of GPCRs can help us to predict their...
