1.1. General Introduction Plesiosaurs are a group of secondarily aquatic diapsid reptiles belonging to the clade Sauropterygia (Carroll, 1988). Diapsids (subclass Diapsida) are a monophyletic group supported by both morphological and molecular data (Lee, 2001) including lizards, snakes, crocodiles and birds, and represent a major sub-group of the amniote vertebrates, i.e. vertebrate organisms w...

. 4 b s h c t This paper concerns the design of distributed algorithms for sharing network bandwidth resources among contending flows. The classical fairness notion is the socalled max-min fairness: F . Kelly [IO] has recently introduced the alternative proportional fairness criterion; we introduce a third criterion. which is naturally interpreted in terms of the delays experienced by ongoing t...

background thyroid dysfunction is the second most common endocrine disease in females of reproductive age. there are controversial data on the adverse effect of subclinical thyroid dysfunctions on adverse feto-maternal outcomes. objectives the current study aimed to identify the prevalence of thyroid dysfunction during pregnancy and to assess the effectiveness of treatment with levothyroxine on...

1 Objectives The objective is to investigate continuous-time models of computation and the complexity thereof. Two complementary approaches will be followed. On one hand, at a more abstract level, the focus is on the theory of real recursive functions. The main objectives are: 1) clarify the algebraic properties of the relations between analog and standard notions of complexity; 2) find analog ...
