The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 4.6 fb −1. No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. The presence of the standard model Higgs boson with a mass in the 270-440 GeV range is excluded at 95% confidence level.

Based on existing references, this thesis intents to promote application of economic analysis of international law in China with pluralistic ways of research (for examples, political, legal and economic) in order to understand the contemporary issues of international law and to have new ideas. The part I is a brief comparison between domestic and international laws from economic perspective, and then a description of applicable economic analysis for international law with an emphasis of its theoretical and practical significances. The part II is focused on Coase's Law & Economics as the basis of economic analysis of international law. The part III to V provide with a few examples of economic analysis of international laws, i.e. law of international economic organization, international environmental law and international humanitarian law. The conclusion is given finally. Key words: theory of international law, economic analysis, law of international economic organization, international environmental law and international humanitarian law Résumé: L'analyse économique de la loi internationale est le nouveau développement des théories de la loi internationale dans la dernière décennie. Basé sur des références existantes, cette thèse tente de promouvoir l'application de l'analyse économique de la loi internaionale en Chine avec des méthodes de recherche pluralistes(par exemple, politique, légale et économique) afin de comprendre les problèmatiques contemporains de la loi internationale et de s'en faire de nouvelles idées. La partie I procède à une comparaison brève entre les lois domestiques et internationales sous l'angle économique et à une description des analyses économiques applicables aux lois internationales en mettant l'accent sur leurs significations théoriques et pratiques. La partie II se concentre sur la Loi de Coase&Economie qui sert de base d'analyse. De la partie III à la partie V, on trouve des exemples de l'analyse économique des lois internationals, par exemple, la loi internationale de l'organisation économique , la loi international de l'environnement et la loi internationale humaniste. Enfin, la conclusion est dégagée. Mots-Clés: théorie de la loi internationale, analyse économique, loi internationale de l'organisation économique, loi internationale de l'environnement et loi internationale humaniste

We used mitochondrial DNA sequences and nuclear microsatellites to test whether the European ruddy duck population is descended solely from the captive population in the UK, which traces to seven individuals imported from the USA in 1948, or, alternatively, has been augmented by natural dispersal of birds from North America. Limited genetic diversity in the European population is consistent with a founder population as small as seven birds. In addition, shifts in allele frequencies at several loci, presumably due to genetic drift in the founding population, result in significant differentiation between the European and North American populations. Despite the recent separation of these populations, almost all individuals could be unambiguously assigned based on their composite genotypes, to one of two distinct populations, one comprising all of the European ruddy ducks we sampled (including those from Iceland and captive birds in the UK) and the other comprising all North American samples. Our results confirm that the European ruddy duck population is likely to derive solely from the captive population in the UK and we find no evidence of recent arrivals from North America or of admixture between ruddy ducks from Europe and North America.
