BACKGROUND Tumor characteristics affect surgical complexity and outcomes of partial nephrectomy (PN). OBJECTIVE To develop an Arterial Based Complexity (ABC) scoring system to predict morbidity of PN. DESIGN, SETTING, AND PARTICIPANTS Four readers independently scored contrast-enhanced computed tomography images of 179 patients who underwent PN. INTERVENTION Renal cortical masses were cat...
Abstract For ℳ and $$ \mathcal{N} N finite module categories over a tensor category \mathcal{C} C , the \mathrm{\mathcal{R}}{ex}_{\mathcal{C}} ℛ ex (ℳ, ) of right exact functors is Drinfeld center \mathcal{Z} Z ( ). We ...
Under suitable assumptions, we extend the inclusion of an additive subcategory X ⊂ A ( = stable category of an exact category with enough injectives) to an S-functor [15] H0]X → A , where H0]X is the homotopy category of chain complexes concentrated in positive degrees. We thereby obtain a new proof for the key result of J. Rickard’s ’Morita theory for Derived categories‘ [17] and a sharpening ...
We present a comparative study of certain invariants defined for group actions and their analogues orbifolds. In particular, we prove that Fadell's equivariant category $G$-spaces coincides with the Lusternik-Schnirelmann orbifolds when is finite.
taking into consideration the fact that convergence of the kurds and shiites on the national security and interests of the islamic republic of iran is a vital necessity, the exact knowledge of nature and category of such a coalition might assist the state security policymaking so that by a better understanding of such a strategy and by comprehension of sensitivity of this opportunity, the polic...
Our first aim is to provide an analog of the Gabriel-Quillen embedding theorem for n-exact categories. Also we give example category that in not n-cluster tilting subcategory, a...
Abstract For a category $\mathcal {E}$ with finite limits and well-behaved countable coproducts, we construct model structure, called the effective on of simplicial objects in , generalising Kan–Quillen structure sets. We then prove that is left right proper satisfies descent sense Rezk. As consequence, obtain associated $\infty $ -category has limits, colimits satisfying descent, locally Carte...
Introduction: Polycystic Ovary Syndrome (PCOS) is one of the most common causes of female infertility. The etiology of this condition is complex. Various genetic and environmental factors have been identified in the pathogenesis of PCOS. The prevalence of this syndrome among Iranian females has been reported between 7.1% to 14.6%. Common symptoms include irregular menstruation, infertility, ova...
the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...
