Schultz and Modified Schultz Polynomials of Chain from Alternating Hexagonal and Quadruple Rings

Maha Waleed Abdulqader , Ahmed Mohammed Ali , Mahmood Median Abdullah

Many topological indices are closely related to chemical and physical properties, especially types of chemical structures that are characterized by the forms of chains of special chemical structures including hexacyclic, pentagonal, and tetracyclic structures. In 1947, the first chemist to find a relationship ...

Weakly r-Supercontinuous Functions

Zahra A. Tanha , Zanyar A. Ameen

In this paper, we use r-open sets to introduce the concept of weakly r-supercontinuous functions. Then, basic properties and a number of connections between these functions and other types of generalized continuous functions are examined. A weakly r-supercontinuous function is weaker than -continuous ...

Comparison of Some Group Variable Selection Methods in High Dimensional Multiple Linear Regression via Simulation Study

Rejin Abdulqader Ibrahim , Hussein Abdulrahman Hashem

In many applications, covariates possess a grouping structure that can be incorporated into the analysis to select important groups as well as important members of those groups. In this paper, we reviewed some group variable selection methods in the penalized regression model. This paper investigates ...
