We study the problem of provision and cost-sharing of a public good in large economies where exclusion, complete or partial, is possible. We search for incentive-constrained efficient allocation rules that display fairness properties. Population monotonicity says that an increase in population should not be detrimental to anyone. Demand monotonicity states that an increase in the demand for the public good (in the sense of a first-order stochastic dominance shift in the distribution of preferences) should not be detrimental to any agent whose preferences remain unchanged. Under suitable domain restrictions, there exists a unique incentive-constrained efficient and demand-monotonic allocation rule: the so-called serial rule. In the binary public good case, the serial rule is also the only incentive-constrained efficient and population-monotonic rule.

A single object must be allocated to at most one of n agents. Money transfers are possible and preferences are quasilinear. We offer an explicit description of the individually rational mechanisms which are Pareto-optimal in the class of feasible, strategy-proof, anonymous and envy-free mechanisms. These mechanisms form a one-parameter infinite family; the Vickrey mechanism is the only Groves mechanism in that family.

Cette thèse décrit deux thèmes principaux: 1) la conception, la synthèse, et l'évaluation biophysique des nucléosides tricycliques, et 2) la synthèse de nagilactone B, un produit naturel norditerpenoïde dilactone de la famille de produits naturels “podolactone”. Le premier chapitre décrit la stratégie de design rationnel des nucléosides nommé “restriction conformationnelle double” basée sur les études de modélisation structurales des duplex ADN–ARN modifiés. Cette stratégie implique un blocage du cycle furanose dans une configuration de type N- ou S, et une restriction de la rotation torsionelle autour de l’angle γ. La première contrainte a été incorporée avec un pont méthylène entre l’oxygène en position 2′ et le carbone 4′ du nucléoside. Cette stratégie a été inspirée par les acides nucléiques bloqués (ou “locked nucleic acid”, LNA). La deuxième contrainte a été réalisée en ajoutant un carbocycle supplémentaire dans l'échafaud de l’acide nucléique bloqué. Les défis synthétiques de la formation des nucléotides modifiés à partir des carbohydrates sont décrits ainsi que les améliorations aux stabilités thermiques qu’ils apportent aux duplex oligonucléïques dont ils font partie. Chapitres deux et trois décrivent le développement de deux voies synthétiques complémentaires pour la formation du noyau de nagilactone B. Ce produit naturel a des implications pour le syndrome de Hutchinson–Gilford, à cause de son habilité de jouer le rôle de modulateur de l’épissage d’ARN pré-messager de lamine A. Ce produit naturel contient sept stereocentres différents, dont deux quaternaires et deux comprenant un syn-1,2-diol, ainsi que des lactones à cinq ou six membres, où le cycle à six ressemble à un groupement α-pyrone. La synthèse a débuté avec la cétone de Wieland-Miescher qui a permis d’adresser les défis structurels ainsi qu’explorer les fonctionnalisations des cycles A, B et D du noyau de nagilactone B.

We study the relaxational dynamics of the one-spin facilitated Ising model introduced by Fredrickson and Andersen. We show the existence of a critical time which separates an initial regime in which the relaxation is exponentially fast and aging is absent from a regime in which relaxation becomes slow and aging effects are present. The presence of this fast exponential process and its associated critical time is in agreement with some recent experimental results on fragile glasses.

The discontinuities in the solutions of systems of conservation laws are widely considered as one of the difficulties in numerical simulation. A numerical method is proposed for solving these partial differential equations with discontinuities in the solution. The method is able to track these sharp discontinuities or interfaces while still fully maintain the conservation property. The motion of the front is obtained by solving a Riemann problem based on the state values at its both sides which are reconstructed by using weighted essentially non oscillatory (WENO) scheme. The propagation of the front is coupled with the evaluation of "dynamic" numerical fluxes. Some numerical tests in 1D and preliminary results in 2D are presented.

We review the progress in the field of front propagation in recent years. We survey many physical, biophysical and cross-disciplinary applications, including reduced-variable models of combustion flames, Reid's paradox of rapid forest range expansions, the European colonization of North America during the 19th century, the Neolithic transition in Europe from 13 000 to 5000 years ago, the description of subsistence boundaries, the formation of cultural boundaries, the spread of genetic mutations, theory and experiments on virus infections, models of cancer tumors, etc. Recent theoretical advances are unified in a single framework, encompassing very diverse systems such as those with biased random walks, distributed delays, sequential reaction and dispersion, cohabitation models, age structure and systems with several interacting species. Directions for future progress are outlined

The University provides a template for the whole of a thesis but if you wish to construct a thesis by using separate files you can use this file for the introductory section. This file contains all of the sections required (Title Page, Abstract, Table of Contents etc). It also has mirror margins for double sided printing and has different odd and even page headers. Support materials for using the template are referenced near the start of the file. You will want to use this in conjunction with the Chapter http://www.edshare.soton.ac.uk/9403/ and End Matter templates http://www.edshare.soton.ac.uk/11998/
