Patterns of phenotypic covariation and correlation in modern humans as viewed from morphological integration
(Wiley-liss, Div John Wiley & Sons Inc, 2003-05)
Proportionality of phenotypic and genetic distance is of crucial importance to adequately focus on population history and structure, and depends on proportionality of genetic and phenotypic covariance. Constancy of phenotypic ...
Operator ordering for generally covariant systems
(North-holland, 2000-12)
The constriant operators belonging to a generally covariant system are found out within the framework of the BRST formalism. The result embraces quadratic Hamiltonian constraints whose potential can factorized as a never ...
Avaliação de modelos geoidais gravimétricos determinados com funções covariâncias planas e esféricas (Estudo de Caso: Estado de São Paulo e adjacências)
(UNIV FEDERAL PARANA, CENTRO POLITECNICO, 2008)
The least squares collocation is a mathematical technique which is used in Geodesy for representation of the Earth's anomalous gravity field from heterogeneous data in type and precision. The use of this technique in the ...
A modified Covariance Matrix Adaptation Evolution Strategy with adaptive penalty function and restart for constrained optimization
(Elsevier B.V., 2014-11-15)
In the last decades, a number of novel meta-heuristics and hybrid algorithms have been proposed to solve a great variety of optimization problems. Among these, constrained optimization problems are considered of particular ...
Variance component estimates applying random regression models for test-day milk yield in Caracu heifers (Bos taurus Artiodactyla, Bovidae)
(Sociedade Brasileira de Genética, 2008-01-01)
Random regression models (RRM) were used to estimate covariance functions for 2,155 first-lactation milk yields of native Brazilian Caracu heifers. The models included contemporary group (defined as year-month of test and ...
Interrelationships Between Bones, Muscles, and Performance: Biting in the Lizard Tupinambis merianae
(Springer, 2014-12-01)
The origins of and potential constraints on the evolution of phenotypic diversity remain one of the central questions in evolutionary biology. The vertebrate skeleton is governed by historical, developmental, architectural, ...
Heat content estimates over sets of finite perimeter
(2016-09)
This paper studies by means of standard analytic tools the small time behavior of the heat content over a bounded Lebesgue measurable set of finite perimeter by working with the set covariance function and by imposing ...

The Poisson-exponential lifetime distribution
(2011-01-01)
In this paper we proposed a new two-parameters lifetime distribution with increasing failure rate. The new distribution arises on a latent complementary risk problem base. The properties of the proposed distribution are ...
