The objetive of this research was to study the relation among body weight and average daily gain in different ages, using principal components analysis. Data on 1663 birth weight (BW), weaning weight adjusted to 230 days ...

In this paper, we discuss the notion of reducibility of matrix weights and introduce a real vector space CR which encodes all information about the reducibility of W. In particular, a weight W reduces if and only if there ...

In this study, we investigated the effects of rapid weight loss followed by a 4-h recovery on judo-related performance. Seven weight-cycler athletes were assigned to a weight loss group (5% body weight reduction by ...

In this paper we obtain for $T^+$, a one-sided singular integral given by a Calder´on-Zygmund kernel with support in $(-infty,0)$, a $L^p(w)$ bound when $win A_1^+$. A. K. Lerner, S. Ombrosi, and C. Pérez in ``$A_{1}$ ...

In this work we give all the order-two hypergeometric operators D, symmetric with respect to some 2 × 2 irreducible matrix-weight W on (0,1) such that DPn=Pnλn00μn with no repetition among the eigenvalues {λn,μn}n∈N0 , ...

Holothurians were heavily exploited worldwide during the last decade. The high prices of the product prompted the opening of new fishing grounds in the west coast of American countries, such as Mexico and Ecuador. In these ...
