[Purpose] This study assessed changes in body composition before and after dialysis in chronic hemodialysis patients and determined the relationships between various body composition parameters and blood lipid levels in these patients. [Subjects] The cross-sectional study included 19 dialysis outpatients (17 men and 2 women, aged 35-82 years). [Methods] Body mass index, body weight, percent bod...

Introduction: Primitive achondrites (IAB irons/winonaites; acapulcoites/lodranites; and brachinites) have chondritic compositions, but nonchondritic textures (from metamorphic through partially melted) [1]. Because of this, they offer a unique insight into the first stages of the differentiation process on asteroids. Acapulcoites and lodranites have textural and mineralogical evidence that they...

Given integers a1, a2, . . . , an, with a1 + a2 + · · ·+ an ≥ 1, a symmetrically constrained composition λ1 + λ2 + · · ·+ λn =M of M into n nonnegative parts is one that satisfies each of the the n! constraints {∑n i=1 aiλπ(i) ≥ 0 : π ∈ Sn } . We show how to compute the generating function of these compositions, combining methods from partition theory, permutation statistics, and lattice-point ...

We study formulas for Fibonacci numbers as sums over compositions. The Fibonacci number Fn+1 is the number of compositions of n with parts 1 and 2. Compositions with parts 1 and 2 form a free monoid under concatenation, and our formulas arise from free submonoids of this free monoid.

Feature modeling is a popular domain analysis method for describing the commonality and variability among the domain products. The current formalisms of feature modelling do not have enough support for automated domain product configuration and validation. We have developed a theory of feature modeling: a feature model is analogous to a definition of a language; a particular feature composition...
