Premeiotic DNA synthesis in the germ cells of the female mouse embryo has been studied by Peters, Levy & Crone (1962) and Crone, Levy & Peters (1965). In this species, with a close synchronization in germinal development, the process of oogenesis which is the period of multiplication by mitotic divisions of the germ cells (oogonia) seems to be followed rapidly (within 24 h) by the first step of...

Abstract Let f be the density function associated to a matrix-exponential distribution of parameters $(\boldsymbol{\alpha}, T,\boldsymbol{{s}})$ . By exponentially tilting , we find probabilistic interpretation which generalizes one phase-type distributions. More specifically, show that for any sufficiently large $\lambda\ge 0$ $x\mapsto \left(\int_0^\infty e^{-\lambda s}f(s)\textrm{d} s\right)...

In this article, stress analysis and energy estimation during cold-roll forming of symmetrical channel sections have been discussed. Geometry of sheet strip is pre-estimated by a shape function. Then longitudinal, transversal and shear strains have been calculated. Using both the Levy-Mises and the Prandtl Reuss equations, and also considering the Bauschinger effect, stress distributions have b...

In this work we deal with a Backward doubly stochastic differential equation (BDSDE) associated to a random Poisson measure. We establish existence and uniqueness of the solution in the case of non-Lipschitz coefficients.

The World Wide Web serves as a huge widely distributed global information service center. The tremendous amount of information on the web is improving day by day. So, the process of finding the relevant information on the web is a major challenge in Information Retrieval. This leads the need for the development of new techniques for helping users to effectively navigate, summarize and organize ...
