On the Moments of the Aggregate Discounted Claims with Dependence Introduced by a FGM Copula

Bargès, Mathieu et al. (2011)

International audience In this paper, we investigate the computation of the moments of the compound Poisson sums with discounted claims when introducing dependence between the interclaim time and the subsequent claim size. The dependence structure between the two random variables is defined by a ...

Improving growth in juvenile turbot (Scophthalmus maximus Rafinesque) by rearing fish in switched temperature regimes

Imsland, A.K. et al. (2007)

The effect of thermal history (16 and 20°C) on growth of juvenile turbot, Scophthalmus maximus (initial mean weight 72.6 g, n = 157) was studied. Fish were divided into four groups, two groups remaining at constant temperature (C16, C20), while fish in the other groups were transferred from either ...

SNP effects depend on genetic and environmental context

Bastiaansen, J.W.M. et al. (2014)

Effects that are estimated for SNP markers depend on LD with the QTL, and interactions of the QTL with other genetic and environmental factors. These factors are often mentioned but rarely studied. Breeding for crossbred performance both brings the need and supplies data for studying these ...

On the Numerical Rank of the Off-Diagonal Blocks of Schur Complements of Discretized Elliptic PDEs

Chandrasekaran, S. et al. (1 juil. 2010)

It is shown that the numerical rank of the off-diagonal blocks of certain Schur complements of matrices that arise from the finite-difference discretization of constant coefficient, elliptic PDEs in two spatial dimensions is bounded by a constant independent of the grid size. Moreover, in three- ...

Work and Pay in Flexible and Rgulated Labor Market : A Generalized Perspective on Insitutional Evolution in Inequality Trends in Europe and the US

DiPrete, Thomas A. et al. (sept. 2006)

In recent years a "unified theory" has emerged out of labor economics, which argues that a combination of "macroeconomic shocks" and flexible labor market institutions in the U.S. has produced strong upward trends in wage inequality, while these same shocks have produced high unemployment and low ...

Image beam from a wire laser

Orlova, E.E. et al. (12 mai 2015)

We demonstrate the formation of a narrow beam from a long (L≫λ) laser with subwavelength transverse dimensions (wire laser) as an image of the subwavelength laser waveguide formed by a spherical lens. The beam is linearly diverging with the angle determined by the ratio of the wavelength to the ...

Size-controlled and redox-responsive supramolecular nanoparticles

Mejia-Ariza, R. et al. (2015)

Control over the assembly and disassembly of nanoparticles is pivotal for their use as drug delivery vehicles. Here, we aim to form supramolecular nanoparticles (SNPs) by combining advantages of the reversible assembly properties of SNPs using host–guest interactions and of a stimulus-responsive ...

Influence of food-type on the population growth rate of the rotifier Brachionus calyciflorus in short-chronic assays

Lürling, M.F.L.L.W. et al. (2006)

The type of food given during short chronic assays with the rotifer Brachionus calyciflorus might be one of the sources of variation in the reproductive rate of the rotifers. Ten green algal species were supplied as monospecific diets to examine variability in rotifer growth rate. In addition, ...

A note on "Khouja and Park, optimal lot sizing under continuous decrease, Omega 31 (2003)"

Teunter, Ruud (9 mars 2004)

textabstractKhouja and Park (Omega 31, 539-545, 2003) analyze the problem of optimizing the lot size under continuous price decrease. They show that the classic EOQ formula can lead to far from optimal solutions and develop an alternative lot size formula using the software package Mathematica. This ...
