Sex differences in mortality rates stem from a complex set of genetic, physiological, psychological, and social causes whose influences and interconnections are best understood in an integrative evolutionary life history framework. Although there are multiple levels of mechanisms contributing to sex based disparities in mortality rates, the intensity of male mating competition in a population m...

In this paper, we present an approach for handling attribute values of object classes with fuzzy information and uncertainty in object-oriented database based on theory hedge algebraic. In this approach, semantics be quantified by quantitative semantic mapping of hedge algebraic that still preserving in order semantics may allow manipulation data on the real domain of attribute in relation with...

Male mammals typically have shorter lifespans than females [1]. Sex differences in survival may result, in part, from sex-specific optima in investment in reproduction, with higher male mortality rates from sexual competition selecting for a "live-fast die-young" strategy in this sex [2]. In the wild, lifespan is also influenced by environmental conditions experienced early in life. Poor condit...

In this paper, we show our results on the bi-directional data exchange between the F-logic language supported by the Flora2 system and the OWL language. Most of the TBox and ABox axioms are translated preserving the semantics between the two representations, such as: proper inclusion, individual definition, functional properties, while some axioms and restrictions require a change in the semant...

Population genetic analyses often require the estimation of parameters such as population size and migration rates. In the 1960s, enzyme electrophoresis was developed; it was the first method to gather co-dominant data from many individuals in many populations relatively easily. Summary statistics methods, such as allele-frequency based F-statistics (Wright 1951), were used to estimate populati...

By considering a least squares approximation of a given square integrable function f : [0, 1] → IR by a shifted L-statistic function (a shifted linear combination of order statistics), we define an index which measures the global influence of the kth largest variable on f . We show that this influence index has appealing properties and we interpret it as an average value of the difference quoti...

Time-course microarray studies require a particular modelling of covariance matrices when measures are repeated on the same individuals. Taking into account the within-subject correlation in the test statistics for differential gene expression involves, however, a large number of parameters when a gene-specific approach is used, which often results in a lack of power due to the small number of ...

Berk and Jones (1979) introduced a goodness of fit test statistic Rn which is the supremum of pointwise likelihood ratio tests for testing H0 : F (x) = F0(x) versus H1 : F (x) = F0(x). They showed that their statistic does not always converge almost surely to a constant under alternatives F , and, in fact that there exists an alternative distribution function F such Rn →d supt>0 N(t)/t where N ...

For a dioecious diploid population subdivided into an arbitrary number of subpopulations, we have derived recurrence equations for the inbreeding coefficient and coancestries between individuals within and among subpopulations and formulas for effective size and F-statistics. Stable population size and structure, discrete generations, autosomal inheritance, and the island migration model are as...

Dedicated to the memory of Philippe Flajolet We consider statistical properties of random integer partitions. In order to compute means, variances and higher moments of various partition statistics, one often has to study generating functions of the form P (x)F(x), where P (x) is the generating function for the number of partitions. In this paper, we show how asymptotic expansions can be obtain...
