Sources of phenotypic variation of wood density and relationships with mean growth in two eucalyptus species in Argentina
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, España, 2021-09-17)
Aims of the study: To describe the radial patterns of wood density, and to identify their main sources of variation, and the potential tradeoffs with mean tree growth, in two Eucalyptus species. Area of study: Mesopotamian ...
Distribution of red king crabs and Tanner crabs in the summer by habitat and depth in an Alaskan fjord

Inflated beta distributions
(SPRINGER, 2010)
This paper considers the issue of modeling fractional data observed on [0,1), (0,1] or [0,1]. Mixed continuous-discrete distributions are proposed. The beta distribution is used to describe the continuous component of the ...
The log-power-normal distribution with application to air pollution
(Hoboken, 2014-02)
In this article, we study an extension of the power-normal distribution to the case of the more flexible log-power-normal distribution. We find the density function and study some properties of the new distribution, deriving ...
Optimal pest control problem in population dynamics
(Springer, 2005-01-01)
One of the main goals of the pest control is to maintain the density of the pest population in the equilibrium level below economic damages. For reaching this goal, the optimal pest control problem was divided in two parts. ...

ON A TEST FOR GENERALIZED UPPER TRUNCATED WEIBULL-DISTRIBUTIONS
(ELSEVIER SCIENCE BV, 1991)
We study upper truncated Weibull random variables with density given by g-beta,delta,tau(t) = beta-delta-t-delta-1 exp(-beta-t-delta)(1 - exp(-beta-tau-delta))-1 for 0 less-than-or-equal-to t less-than-or-equal-to tau (tau ...
Climate fluctuations as a cause of rarity in fairy armadillos
(Elsevier Gmbh, 2015-07)
Despite having a moderately large distributional area, both the pink fairy armadillo (Chlamyphorus truncatus) and particularly the Chacoan fairy armadillo (Calyptophractus retusus), which are among the least known xenarthrans, ...
A Piecewise Curve-Fitting Technique for Vertical Oceanographic Profiles and its Application to Density Distribution
(Journal of Oceanography, 2008-01-01)
A unified method of approximation, extrapolation, and objective layering is offered for processing vertical oceanographic profiles. The method is demonstrated using seawater density and consists of adjustable splitting of ...
