Background: The biting behaviour and dispersal of insect vectors in the field underlies the transmission of many diseases. Here, a novel collection methodology coupled with the molecular analysis of blood-meal sources and ...

This paper revisits, in a multi-thread context, the so-called multi-parameter or block conjugate gradient (B-CG)methods, first proposed as sequential algorithms by O’Leary and Brezinski, for the solution of the linear ...

We revisit the gamma–gamma Bayesian chain-ladder (BCL) model for claims reserving in non-life insurance. This claims reserving model is usually used in an empirical Bayesian way using plug-in estimates for the variance ...

In this paper we demonstrate how to develop analytic closed form solutions to optimal multiple stopping time problems arising in the setting in which the value function acts on a compound process that is modified by the ...

We investigate an everywhere defined notion of solution for control systems whose dynamics depend non-linearly on the control u and state x, and are affine in the time derivative u˙. For this reason, the input u, which is ...

Not many years ago it was usual to comment on the lack of an open lexicalsemantic knowledge base, following the lines of Princeton WordNet, but for Portuguese. Today, the landscape has changed significantly, and researchers ...

Aborda aspectos relativos à avaliação de bibliotecas digitais, consideradas como dispositivos informacionais que podem auxiliar na democratização da informação mediada pelas tecnologias digitais. Tais bibliotecas podem ser ...

After recalling the notion of L1 limit solution for a dynamics which is affine in the (unbounded) derivative of the control, we focus on the possible occurrence of the Lavrentiev phenomenon for a related optimal control ...

The increasing use of Web for both scholarly publishing and information retrieval emphasizes the need for mechanisms to support efficient indexing and effective information retrieval. Manual indexing and knowledge ...
