ur aim of this  paper  is  to introduce the concept of $L$-double fuzzy rough sets in whichboth constructive and axiomatic approaches are used. In constructive approach, a pairof $L$-double fuzzy lower (resp. upper) approximation operators is defined  and the basic properties of them  are studied.From the viewpoint of the axiomatic approach, a set of axioms is constructed to characterize the $L...

autoimmune lymphoproliferative syndrome (alps) is a rare, inherited disorder of immune dysregulation secondary to defective lymphocyte apoptosis. this leads to uninhibited proliferation of lymphoid tissue manifesting with lymphadenopathy, hepatosplenomegaly, autoimmune cytopenia, and an increased risk of lymphoid malignancy. we report a 2 year old boy with fever, generalized lymphadenopathy, he...

introduction the aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (appj) and interactions of this technology with double-stranded dna using the polymerase chain reaction (pcr) and single-strand conformation polymorphism (sscp) techniques. materials and methods the plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...

the majority of coronary artery fistulas (cafs) are congenital. the anomaly accounts for 0.4% of congenital heart defects and approximately 50% of pediatric coronary vasculature anomalies. twenty percent of people with congenital cafs have other concomitant cardiac anomalies, most frequently aortic and pulmonary atresia and patent ductus arteriosus. it is worthy of note that caf with the tetral...

In our working toward the rational design and synthesis of cluster-based supramolecular architectures, a set of new [WS4Cu4]- or [MoOS3Cu3]-based supramolecular assemblies have been prepared from reactions of preformed cluster compounds [Et4N]4[WS4Cu4I6] (1) and [(n-Bu)4N]2[MoOS3Cu3X3] (2, X = I; 3, X = SCN) with flexible ditopic ligands such as dipyridylsulfide (dps), dipyridyl disulfide (dpds...

The purpose of this paper is to introduce the concept of soft double fuzzy semi-topogenous order. Firstly, we give the definition of soft double fuzzy semi-topogenous order. Secondly, we induce a soft double fuzzy topology from a given soft double fuzzy semi-topogenous order by using soft double fuzzy interior operator.
