In the restricted elliptical linear model, an approximation for the risk of a general shrinkage estimator of the regression vector-parameter is given. Superiority condition of the shrinkage estimator over the restricted estimator is investigated under the elliptical assumption. It is evident from numerical results that the shrinkage estimator performs better than the unrestricted one...

We study compositions of the integer n in which the first part, successive differences, and the last part are constrained to lie in prescribed sets L,D,R, respectively. A simple condition on D guarantees that the generating function f(x,L,D,R) has only a simple pole on its circle of convergence and this at r(D), a function independent of L and R. Thus the number of compositions is asymptotic to...

background: a high-fat diet (hfd) and fat accumulation promote the oxidative stress formation, which in turn has hazardous effects on reproductive system and fertility. therefore, the present study examines the potential positive effects of a restricted high-fat diet (rhfd) and antioxidants consumption on sperm parameters in rats. methods: 48 male albino wistar rats divided to four groups (n=12...

in this paper, he‘s variational iteration method is applied to fredholm integral equations of the second kind. to illustrate the ability and simplicity of the method, some examples are provided. the results reveal that the proposed method is very effective and simple and for first fourth examples leads to the exact solution.

OBJECTIVE This study assessed the degree of interindividual responses in energy intake (EI) to an imposed sleep restriction versus habitual sleep duration protocol. It also investigated participant (age, sex, ethnicity, and BMI) and study (study site and protocol order) characteristics as potential contributors to the variance in EI responses to sleep restriction between individuals. METHODS ...
