Using one of Wodzicki's examples of H-unital algebras [14] we exhibit a ring whose derived category contains a smashing subcategory which is not generated by small objects. This disproves the generalization to arbitrary triangulated categories of a conjecture due 1. Statement of the conjecture We refer to [7] for a nicely written analysis of the following setup: Let S be a triangulated category...

BACKGROUND The role of repeat fine-needle aspiration (RFNA) or core needle biopsy (CNB) has not been established in nodules categorized as atypia/follicular lesion of undetermined significance (AUS/FLUS). OBJECTIVE The purpose of this study was to retrospectively determine whether CNB is more useful for management decisions than RFNA at each subcategory of AUS/FLUS nodules. METHODS This stu...

The subcategory of a category and product of categories is defined. The inclusion functor is the injection (inclusion) map E ↪→ which sends each object and each arrow of a Subcategory E of a category C to itself (in C). The inclusion functor is faithful. Full subcategories of C, that is, those subcategories E of C such that HomE(a,b) = HomC(b,b) for any objects a,b of E, are defined. A subcateg...

the aim of the present paper is to define and study (ic)$lm$-fuzzytopological spaces, a generalization of (weakly) induced $lm$-fuzzytopological spaces. we discuss the basic properties of(ic)$lm$-fuzzy topological spaces, and introduce the notions ofinterior (ic)-fication and exterior (ic)-fication of $lm$-fuzzytopologies and prove that {bf iclm-ftop} (the category of(ic)$lm$-fuzzy topological ...

There are two main approaches to obtaining “topological” cartesian-closed categories. Under one approach, one restricts to a full subcategory of topological spaces that happens to be cartesian closed — for example, the category of sequential spaces. Under the other, one generalises the notion of space — for example, to Scott’s notion of equilogical space. In this paper we show that the two appr...

The present study is aimed at investigating the relationship among Iranian EFL teachers’ reflective teaching, reflective thinking and classroom management ability. To this purpose, 102 male and female EFL teachers, aged between 25 and 40, with different academic background who were teaching at different levels, were chosen to fill in three questionnaires on reflective thinking, reflective teach...

For a symmetric monoidal-closed category X and any object K, the category of K-Chu spaces is small-topological over X and small cotopological over X . Its full subcategory of M-extensive K-Chu spaces is topological over X when X is Mcomplete, for any morphism class M. Often this subcategory may be presented as a full coreflective subcategory of Diers’ category of affine K-spaces. Hence, in addi...

this study examined the effects of cooperative learning techniques (clt) on vocabulary achievement of reflective/impulsive iranian efl learners. from among 130 students at fajr institute in dehdasht, kohkiloyeh and boyer ahmad province, iran, 90 participants were selected based on their performance on the oxford placement test (opt). the participants were then divided into two experimental grou...

For an Artinian (n− 1)-Auslander algebra Λ with global dimension n(≥ 2), we show that if Λ admits a trivial maximal (n − 1)-orthogonal subcategory of modΛ, then Λ is a Nakayama algebra and the projective or injective dimension of any indecomposable module in modΛ is at most n− 1. As a result, for an Artinian Auslander algebra with global dimension 2, if Λ admits a trivial maximal 1-orthogonal s...
