Th e search for interventions to reduce avoidable readmissions aft er an exacerbation of COPD has attracted substantial attention aft er the Centers for Medicare & Medicaid Services included COPD exacerbations in its Hospital Readmissions Reduction Program. 1 We read with great interest the study by Jennings et al 2 in a recent issue of CHEST (May 2015) and applaud the authors for conducting a ...
National surveys have revealed significant differences in patient outcomes following admission to hospital with acute exacerbation of COPD which are likely to be due to variations in care. We developed a care bundle, comprising a short list of evidence-based practices to be implemented prior to discharge for all patients admitted with this condition, based on a review of national guidelines and...
We show that holomorphic bundles on O(−k) for k ≥ 0 are algebraic. We also show that such bundles are trivial outside the zero section. 1 Preliminaires The line bundle on P given by transition function z is usually denoted O(−k). Since we will be studying bundles over this space, we will denote O(−k) by Mk when we want to view this space as the base of a bundle. We give Mk the following charts ...
In this paper we investigate holomorhic rank-2 vector bundles with trivial determinant and second Chern class one on some nonKähler surfaces. The main dificulty one encounters when dealing with holomorphic vector bundles over nonprojective manifolds, is the presence of nonfiltrable such bundles (that is, bundles with no filtration by torsion-free coherent subsheaves) or even of irreducible ones...
We show that every orbispace satisfying certain mild hypotheses has ‘enough’ vector bundles. It follows the $K$ -theory of finite rank bundles on such orbispaces is a cohomology theory. Global presentation results for smooth orbifolds and derived also follow.
We are interested in those bundles on P that admits a resolution of the form 0 → C ⊗ E φ −→ C t ⊗ F → C → 0. In this paper we prove that, under suitable conditions on E, F , a generic bundle with this form is either simple, or canonically decomposable. As applications we provide an easy criterion for the stability of such bundles on P and we prove the stability of all Steiner exceptional bundle...
Product bundles may consist of multiple units of a single product (" uniform " bundles) or multiple units of more than one product (" mixed " bundles). In this paper, we examine consumer evaluations of mixed and uniform bundles. Two factors can explain preferences for mixed bundles. First, consumers may perceive each additional unit of a particular product as possessing less marginal value. Sec...
