Forhigh-dimensional chemometric data, the inverse matrix X t − 1 problem in regression models is a difficulty. Multicollinearity and identification result from problem. The usage of least absolute shrinkage sel...

Background Thalassemia is a group of congenital disorders which is characterized by a deficient synthesis of alfa or beta globulin chains in hemoglobin molecules. Due to the problems resulting from changes in face, especially in dento-maxillary regions, such patients require special attention regarding oral health. Thus in this study, we aimed to assess the dento-maxillofacial changes in Beta-t...

in this paper we investigate generalized topologies generated by a subbase ofpreorder relators and consider its application in the concept of the complement. we introducethe notion of principal generalized topologies obtained from the new type of open sets andstudy some of their important properties.

A nonzero fuzzy open set () of a fuzzy topological space is said to be fuzzy minimal open (resp. fuzzy maximal open) set if any fuzzy open set which is contained (resp. contains) in is either or itself (resp. either or itself). In this note, a new class of sets called fuzzy minimal open sets and fuzzy maximal open sets in fuzzy topological spaces are introduced and studied which are subclasses ...
