In this paper, we introduce the notion of a fuzzy ideal in subtraction algebras, and give some conditions for a fuzzy set to be a fuzzy ideal in subtraction algebras. We also pose three questions on fuzzy ideals of subtraction algebras.
INTRODUCTION The aim of this paper was to evaluate the angioarchitectural factors that can induce concurrent cavernous malformation (CM) in the territory of developmental venous anomaly (DVA). METHODS From January 2006 to December 2007, 21 patients with 23 CMs in the territory of DVA were retrospectively analyzed (M; F = 12; 9, mean age = 53.3).… (More)
The notions of a bipolar fuzzy regularity, a bipolar fuzzy regular subalgebra, a bipolar fuzzy filter, and a bipolar fuzzy closed quasi filter in BCH-algebras are introduced, and several properties are investigated. A characterization of a bipolar fuzzy filter is provided.
BACKGROUND Post-contrast T1 mapping by modified Look-Locker inversion recovery (MOLLI) sequence has been introduced as a promising means to assess an expansion of the extra-cellular space. However, T1 value in the myocardium can be affected by scanning time after bolus contrast injection. In this study, we investigated the changes of the T1 values according… (More)
The notion of coderivations of ranked bigroupoids is discussed by Alshehri et al. in press, and their generalized version is studied by Jun et al. under review press. In particular, Jun et al. under review press studied coderivations of ranked bigroupoids. In this paper, the generalization of coderivations of ranked bigroupoids is discussed. The notion of… (More)
PURPOSE Patients with non-small cell lung cancer (NSCLC) and simultaneously having brain metastases at the initial diagnosis, presenting symptoms related brain metastasis, survived shorter duration and showed poor quality of life. We analyzed our experiences on surgical treatment of brain metastasis in patients with NSCLC. MATERIALS AND METHODS We… (More)
