Dividing the FEV1 into its component parts.
TO THE EDITOR: Sorkness et al. (1) show that the forced expiratory volume in 1 s (FEV1) expressed as percent predicted can be broken down into its two components, forced vital capacity (FVC) and FEV1/FVC, also expressed as percent predicted. They claim that “this is a novel approach [for partitioning the FEV1] in a quantitative manner”. In fact, this quantitative novelty was introduced 12 years...
متن کاملOn Partitioning Grids into Equal Parts
Let an edge cut partition the vertex set of an n-dimensional quadratic grid with the side length a into k subsets A1, ..., Ak with ||Ai| − |Aj || ≤ 1. We consider the problem of determining the minimal size c(n, k, a) of such a cut and present its asymptotic c(n, k, a) ∼ nan−1 n √ k as a, k →∞ and k/an → 0. The same asymptotic holds for partitioning of the n-dimensional torus. We present also s...
متن کاملan exploration into the criterion for dividing the jurists into akhbārī and uṣūlī
dividing the jurists into akhbārī (traditionist) and uṣūlī (legal theorist) is the most important division that dichotomizes the imāmī jurists into two groups. in jurisprudential and legal (uṣūlī) books, there are many instances of characterizing a jurist as akhbārī or uṣūlī, but what is important in this division is the criterion for this division. what is manifested in the first place as the ...
متن کاملToward an Antiphony Framework for Dividing Tasks into Subtasks
Task analysis is a staple of ergonomics, neuroergonomics, human factors, and experimental psychology inquiry, and often benefits from granularity beyond the task level to the subtask level. The concept and challenge of identifying the subcomponents of tasks are neither new, nor solved. Practitioners routinely identify individually internally consistent and yet conflicting subdivisions. The chal...
متن کاملCyclic asymptotic behaviour of a population reproducing by fission into two equal parts
We study the asymptotic behaviour of the following linear growthfragmentation equation B Btupt, xq ` B Bx ` xupt, xq ̆ `Bpxqupt, xq “ 4Bp2xqupt, 2xq, and prove that under fairly general assumptions on the division rate Bpxq, its solution converges towards an oscillatory function, explicitely given by the projection of the initial state on the space generated by the countable set of the dominant ...
