We present the discovery and characterisation of the exoplanets WASP-113b and WASP-114b by the WASP survey, {\it SOPHIE} and {\it CORALIE}. The planetary nature of the systems was established by performing follow-up photometric and spectroscopic observations. The follow-up data were combined with the WASP-photometry and analysed with an MCMC code to obtain system parameters. The host stars WASP-113 and WASP-114 are very similar. They are both early G-type stars with an effective temperature of $\sim 5900\,$K, [Fe/H]$\sim 0.12$ and $T_{\rm eff}$ $\sim 4.1$dex. However, WASP-113 is older than WASP-114. Although the planetary companions have similar radii, WASP-114b is almost 4 times heavier than WASP-113b. WASP-113b has a mass of $0.48\,$ $\mathrm{M}_{\rm Jup}$ and an orbital period of $\sim 4.5\,$days; WASP-114b has a mass of $1.77\,$ $\mathrm{M}_{\rm Jup}$ and an orbital period of $\sim 1.5\,$days. Both planets have inflated radii, in particular WASP-113 with a radius anomaly of $\Re=0.35$. The high scale height of WASP-113b ($\sim 950$ km ) makes it a good target for follow-up atmospheric observations. [less ▲]

We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18Mj and radius 1.35Rj. This is one of the least massive planets discovered by the WASP project. It orbits a bright host star (V = 10.16) of spectral type G5 with a period of 4.17 days.WASP-127b is a low density planet which has an extended atmosphere with a scale height of 2500+/-400 km, making it an ideal candidate for transmission spectroscopy. WASP-136b and WASP-138b are both hot Jupiters with mass and radii of 1.51 Mj and 1.38 Rj, and 1.22 Mj and 1.09 Rj, respectively. WASP-136b is in a 5.22-day orbit around an F9 subgiant star with a mass of 1.41 Msun and a radius of 2.21 Rsun. The discovery of WASP-136b could help constraint the characteristics of the giant planet population around evolved stars. WASP-138b orbits an F7 star with a period of 3.63 days. Its radius agrees with theoretical values from standard models, suggesting the presence of a heavy element core with a mass of 10 Mearth. The discovery of these new planets helps in exploring the diverse compositional range of short-period planets, and will aid our understanding of the physical characteristics of both gas giants and low density planets.

Après une période de « dédiabolisation » et grâce à une base électorale croissante, de plus en plus de partis d'extrême droite européens se revendiquent aujourd’hui comme démocratiques. En écartant de la scène politique et médiatique leurs membres les plus violents, en respectant les procédures électorales et en proposant des programme alternatifs vis-à-vis des partis traditionnels, les organisations d’extrême droite s’intégreraient durablement au sein de nos systèmes politiques jusqu’à se présenter, dans certains pays, comme les véritables représentants du peuple, les défenseurs des libertés individuelles et les promoteurs d’une « véritable démocratie » loin des bureaucrates et technocrates de Bruxelles, loin des élites politiques et économiques qui ont confisqué le pouvoir aux citoyens. Liberté d’expression, laïcité, référendum, souveraineté populaire,… Autant de valeurs, autant de principes qui jettent la confusion dans un débat censé opposer la démocratie à l’extrême droite.

We investigate the kinematics and ionization structure of the broad emission line region of the gravitationally lensed quasar QSO2237+0305 (the Einstein cross) using differential microlensing in the high- and low-ionization broad emission lines. We combine visible and near-infrared spectra of the four images of the lensed quasar and detect a large-amplitude microlensing effect distorting the high-ionization CIV and low-ionization Hα line profiles in image A. While microlensing only magnifies the red wing of the Balmer line, it symmetrically magnifies the wings of the CIV emission line. Given that the same microlensing pattern magnifies both the high- and low-ionization broad emission line regions, these dissimilar distortions of the line profiles suggest that the high- and low-ionization regions are governed by different kinematics. Since this quasar is likely viewed at intermediate inclination, we argue that the differential magnification of the blue and red wings of Hα favors a flattened, virialized, low-ionization region whereas the symmetric microlensing effect measured in CIV can be reproduced by an emission line formed in a polar wind, without the need of fine-tuned caustic configurations.

Le sexe ratio secondaire, défini comme la proportion de mâles à la naissance, est de 52% chez les bovins, avec des variations selon les populations étudiées de 46 à 57%. Il est plus élevé lors des premières étapes du développement embryonnaire, et les conceptus mâles meurent proportionnellement plus au cours de la gestation que les conceptus femelles. Les facteurs de variation potentiels sont nombreux, mais peu d’effets sont unanimement observés. L’effet de la parité ou du statut social de la vache ne sont pas clairement démontrés. Les ovulations sur l’ovaire droit donneraient naissance à une plus forte proportion de mâles ; le rôle du taureau est probablement limité et la répétabilité du sexe du veau d’une gestation à l’autre est faible. Le moment de l’insémination par rapport à l’ovulation ne semble pas avoir d’influence alors qu’il aurait pu constituer un moyen de maîtrise assez simple à mettre en œuvre. [less ▲]

One of the basic rules in trade law is the freedom of trade. However, such rule encounters some limitations, derogations and exceptions when the object of trade is constituted by strategic and sensitive items. The concept of “strategic trade” is one of the most ambiguous ones, and there is not a common definition of it. Even if the General Agreements on Tariffs and Trade (GATT) does not offer such an explanation, its Article XXI can be construed as referring to strategic trade, as much as it states that the provisions of GATT (grounded on free trade) need not apply in cases where “essential security interests” are involved. The concept of “essential security interests” is also vague, as it is left upon the individual parties to the GATT to decide what it means. Despite such ‘slippery slope’ in the definition of terms, it results, however, that strategic trade is linked to norms and measures that aim at controlling trade, in order to ensure the protection of non economic needs, such as national security, public morals, public order, etc. This area finds at the intersection of commercial and foreign policy. For ensuring the protection of non economic interests, it is necessary to introduce measures that provide for controls on all activities conducted by individuals, organizations, and groups regarding goods, equipment, materials, services related to strategic items: these activities shall cover the whole supply chain, including design, development, production, possession, delivery, transport, transit, trans-shipment, financing, brokering, exports, re-exports, transfers and imports. The actors intervening in the draft of rules and controls are mainly the States, and the international and regional organiza- tions; then, important subjects are national licencing authorities and enforcement agencies such as customs, border security, police and armed forces, if needed. The targets of such measures of control could be the States, if the rules at the international or regional level are addressing them, and/or the operators involved in strategic trade. Considering the ways in which States organize such controls, the reality shows that they have introduced control lists, licences and authorisations granted on the basis of conditions and criteria, information-sharing and cooperation between authorities and operators, duties of transparency through reports, records, dec- larations and screenings. Moreover, measures exist that consist of restrictions, bans and penalties providing that consequences in case of violation of strategic trade rules. Therefore, the issue of sanctions is a relevant part of the strategic trade law, and it inserts within that context. The purpose of this contribution is to define what sanctions in strategic trade mean and to systematize them accordingly. In particular, the sanctions are categorized into three groups: A. “supranational sanctions”; B. “implementing sanctions”; C. tertium genus: “unilateral sanctions” and “countermeasures”. [less ▲]

We propose a simple but fundamental methodological change to Fama and French (1993) factor construction procedure. Consistent with Lambert and Hübner (2013) sequential sorting procedure to classify stocks, our methodology controls ex ante for pricing errors produced by multifactor models. Our size and value factors deliver less specification errors when used to price portfolios, especially regarding low size and high B/M stocks. Furthermore, this alternative framework generates much stronger “turn-of-the-year” size and “through-the-year” book-to-market effects than conventionally documented. The factors also display a slight competitive advantage on the taxonomy of low turnover market anomalies defined by Novy-Marx and Velikov (2015). [less ▲]

Dans la documentation papyrologique relative aux pratiques médicales de l’Égypte gréco-romaine et byzantine, le genre des listes de produits pharmaceutiques n’a encore jamais fait l’objet, ni d’un inventaire, ni d’une étude exhaustifs. Dans le cadre de nos recherches doctorales sur la typologie des papyrus documentaires grecs et latins à caractère médical, c’est cette lacune que l’on se propose de combler, d’une part en cataloguant, au moyen de la fiche Mertens-Pack³ du CEDOPAL, la trentaine de listes de produits pharmaceutiques provenant d’Égypte, écrites en grec sur papyrus et ostracon (IIIe s. av. J.-Chr.-VIIe s. apr. J.-Chr.), auxquelles on ajoutera deux listes latines sur tablettes de bois, provenant du camp romain de Vindolanda (c. 100p), et, d’autre part, en analysant les aspects formels, paléographiques, textuels et contextuels de ces documents médicaux qui peuvent correspondre, soit à un inventaire de droguiste, soit à une commande, soit à une ou plusieurs recettes dont l’état fragmentaire du support a fait disparaître les proportions. On comparera les données obtenues avec d’autres pièces papyrologiques, spécialement les nombreuses prescriptions médicales, ainsi que les comptes, les reçus de paiement ou encore les lettres privées relatives à des demandes de médicaments ou à la livraison de substances pharmaceutiques.
