Dans cet exposé accessible au plus grand nombre, nous présentons à travers quelques jeux célèbres (la tablette de chocolat empoisonnée, le jeu de Nim, le jeu de Wythoff, le paradoxe du prisonnier) les notions de positions gagnante ou perdante et de stratégie. Cela motive l'analyse mathématique d'un jeu. Bien au-delà du simple caractère ludique, nous montrons l'intérêt de la notion de jeu comme modèle dans des domaines aussi variés que l'informatique, la biologie ou encore l'économie mais aussi les interactions existant avec d'autres branches des mathématiques.

L'article revient sur la focalisation extrême sur "l'éhtique" en politique. Le mot n'est utilisé que dans un contexte particulier : les mandataires tirent-ils des bénéfices indûs de l'exercice du mandat ? Mais cette question n'est que le degré zéro de l'éthique : le politique "intègre" peut être conservateur ou progressiste, extrémiste ou modéré, de gauche ou de droite. Quelle politique va-t-il appliquer et quels intérêts va-t-il servir (au-delà des siens) ? Là est la vraie question éthique en politique. [less ▲]

The runaway O-type binaries HD 14633 and HD 15137 were likely ejected from the cluster of their birth by supernovae explosions in close binaries. Neither star is a known X-ray source, but they likely contain neutron stars and may be weak stellar wind accretion systems. Hence the two binaries have been classified as "quiet HMXBs". Here we present new optical spectra of these spectroscopic binaries and reassess their orbits. We also present preliminary results from recent XMM-Newton observations, intended to detect the hard power-law spectrum from accreting or quiescent neutron star companions and reveal the evolutionary history of these intriguing runaways.

Styrene has been polymerized by a Quinone Transfer Radical Polymerization (QTRP) based on the redox reaction of an ortho-quinone and a metal catalyst. Several metal acetylacetonates have been tested in this work. The radical polymerization of styrene is largely controlled when phenanthrenequinone (PhQ) is used with catalytic amounts of Co(acac)(2), Ni(acac)(2), Mn(acac)2 or 3, and Al(acac)(3). As a rule, in the presence of all these metallic complexes, the polystyrene molar mass increases with the monomer conversion, and polydispersity (M-w/M-n) is in the 1.3-1.6 range (at least until 40% monomer conversion). Styrene polymerization has also been resumed by polystyrene chains prepared by QTRP. In the specific case of manganese acetylacetonates, an amine or phosphine ligand has to be added for the control to be effective. Finally, two mechanistic hypotheses have been proposed, depending on whether the oxidation state of the metal can be easily changed or not. [less ▲]

Several o-quinones have been tested as control agents for the quinone transfer radical polymerization (QTRP) of styrene in the presence of cobalt(II) acetylacetonate. In contrast to the commercially available 3,5-di-tert-butyl-o-benzoquinone (3,5-DtBBQ) and tetrachloro-1,2-benzoquinone (tetrachloro-1,2-BQ), 3,6-dimethoxy-9,10-phenanthrenequinone (3,6-DMPhQ) imparts a better control to the radical polymerization of styrene compared to 9,10-phenanthrenequinone (PhQ) used as a reference. Indeed, whenever 3,6-DMPhQ is added with a catalytic amount of metal complexes (Co(acac)(2) or Al(acac)(3)), the evolution of the molar mass with the monomer conversion is linear, and low polydispersity (M-w/M-n similar to 1.1-1.2) is observed until very high monomer conversion (similar to 90%). Finally, the methoxy protons of 3,6-DMPhQ have been detected by H-1 NMR analysis of the polystyrene end groups, which is important mechanistic information. [less ▲]

ortho-Quinones, such as phenanthrenequinone and 3,6-dimethoxyphenanthrenequinone, added with a catalytic amount of metal complexes, impart control to styrene polymerization via the previously reported quinone transfer radical polymerization (QTRP) process. In this study, compounds that mimic the dormant species proposed in the QTRP mechanism have been synthesized and tested as initiators in the presence of cobalt(II) acetylacetonate. These compounds, and particularly 3,6-dimethoxy-10-hydroxy-10-(l-phenyl-ethyl)-phenanthren-9-one, are effective control agents for the radical polymerization of styrene, in agreement with the recently proposed mechanism. Moreover, the induction period, which has been systematically reported in the presence of ortho-quinones, is no longer observed. The end capping of the polystyrene chains by the control agent has been confirmed by H-1 NMR analysis. [less ▲]
