Dichotomization: 2 × 2 (×2 × 2 × 2...) categories: infinite possibilities
BACKGROUND Consumers of epidemiology may prefer to have one measure of risk arising from analysis of a 2-by-2 table. However, reporting a single measure of association, such as one odds ratio (OR) and 95% confidence interval, from a continuous exposure variable that was dichotomized withholds much potentially useful information. Results of this type of analysis are often reported for one such d...
متن کاملتعیین غلظت کریپتوفیکس 2، 2، 2 در رادیوداروی [18F]FDG
غلظت کریپتوفیکس 2،2،2 در محلول‌های [18F]FDG و استانداردهای کریپتوفیکس 2،2،2 به دو روش آشکارسازی (ترکیب کریپتوفیکس 2،2،2) با بخار ید و معرف یدوپلاتینات تعیین شد. در هر دو روش، تفاوت غلظت محلول‌های کریپتوفیکس، به صورت تفاوت در شدت رنگ لکه‌های آشکار شده بر روی TLC نمایان شد. حد تشخیص کریپتوفیکس با بخار ید و معرف یدوپلاتیتات به ترتیب ppm25 و ppm2 می‌باشد. هر دو روش را می‌توان برای پذیرش ...
متن کاملCell 2-representations of finitary 2-categories
We study 2-representations of finitary 2-categories with involution and adjunctions by functors on module categories over finite dimensional algebras. In particular, we define, construct and describe in detail (right) cell 2-representations inspired by KazhdanLusztig cell modules for Hecke algebras. Under some natural assumptions we show that cell 2-representations are strongly simple and do no...
متن کاملTransitive 2-representations of Finitary 2-categories
In this article, we define and study the class of simple transitive 2-representations of finitary 2-categories. We prove a weak version of the classical Jordan-Hölder Theorem where the weak composition subquotients are given by simple transitive 2-representations. For a large class of finitary 2-categories we prove that simple transitive 2-representations are exhausted by cell 2-representations...
متن کامل2 00 2 Category of A ∞ - categories
We define natural A∞-transformations and construct A∞-category of A∞-functors. The notion of non-strict units in an A∞-category is introduced. The 2-category of (unital) A∞-categories, (unital) functors and transformations is described. The study of higher homotopy associativity conditions for topological spaces began with Stasheff’s article [Sta63, I]. In a sequel to this paper [Sta63, II] Sta...
