Microlensing can provide a useful tool to probe binary distributions down to low-mass limits of binary companions. In this paper, we analyze the light curves of eight binary-lensing events detected through the channel of high-magnification events during the seasons from 2007 to 2010. The perturbations, which are confined near the peak of the light curves, can be easily distinguished from the central perturbations caused by planets. However, the degeneracy between close and wide binary solutions cannot be resolved with a 3σ confidence level for three events, implying that the degeneracy would be an important obstacle in studying binary distributions. The dependence of the degeneracy on the lensing parameters is consistent with a theoretical prediction that the degeneracy becomes severe as the binary separation and the mass ratio deviate from the values of resonant caustics. The measured mass ratio of the event OGLE-2008-BLG-510/MOA-2008-BLG-369 is q ~ 0.1, making the companion of the lens a strong brown dwarf candidate. [less ▲]

CoRoT is a space telescope which aims at studying internal structure of stars and detecting extrasolar planets. We present here a list of transits detected in the light curves of stars observed by CoRoT in two fields in the anti-center direction: the LRa03 one observed during 148 days from 3 October 2009 to 1 March 2010 followed by the SRa03 one from the 5 March 2010 to the 29 March 2010 during 25 days. 5329 light curves for the LRa03 field and 4169 for the SRa03 field were analyzed by the detection team of CoRoT. Then some of the selected exoplanetary candidates have been followed up from the ground. In the LRa03 field, 19 exoplanet candidates have been found, 8 remain unsolved. No secured planet has been found yet. In the SRa03 field, there were 11 exoplanetary candidates among which 6 cases remain unsolved and 3 planets have been found: CoRoT-18b, CoRoT-19b, CoRoT-20b.

Créée en 1997 dans l'esprit du modèle québécois, l'ASBL Parlement Jeunesse de la Communauté française organise annuellement une simulation parlementaire à destination de jeunes francophones résidants en Belgique, âgés de 17 à 26 ans. Cette initiative citoyenne permet ainsi à une centaine de jeunes, idéalement issus de tous milieux et de tous horizons, de découvrir les rouages internes de la démocratie, conformément aux mécanismes et procédures propres au système parlementaire belge. Là où nombre d'études scientifiques sur l'engagement politique des jeunes s'accordent sur la prévalence d'un désintérêt manifeste et – plus largement – sur une tendance générale au déclin de l'engagement politique chez les jeunes, l'action citoyenne mise en œuvre par le Parlement Jeunesse témoigne en réalité de l'existence de formes moins classiques – dans le cas présent, associative – de socialisation des jeunes à la « chose politique ». L’objectif général poursuivi dans cette contribution est d'identifier la nature et les fondements de l'engagement politique déployé à travers cette jeune initiative, ainsi que d’en mesurer la portée et les limites. Dès lors, en quoi le Parlement Jeunesse participe-t-il de l’engagement politique des jeunes ? Ne contribue-t-il qu’au renforcement d’un intérêt politique latent et préexistant ? A contrario, participe-t-il de la construction d’un engagement politique au départ d’un processus d’apprentissage pratique des rouages de la démocratie parlementaire ? En d’autres termes, quelles sont les forces et les faiblesses de cette initiative citoyenne en terme de socialisation politique de la jeunesse ? [less ▲]

The additional energy spread due to sample porosity was implemented in the SIMNRA simulation code, version 6.60 and higher. Deviations of the path length and energy loss distributions from the ones expected from a Poisson distribution of the number of traversed pores are taken into account. These deviations are due to the interaction of pores at higher pore concentrations by overlap or blocking. The skewnesses of the energy distributions are approximated by two-piece normal distributions with identical first three moments. Propagation of porosity-induced energy spread in thick layers is taken into account. Calculated results are compared to experimental data obtained with thin TiO2 mesoporous films measured by Rutherford backscattering (RBS),transmission electron microscopy (TEM), and atmospheric poroellipsometry.

Model parameterization through adjustment to field data is a crucial step in the modeling and the understanding of the drainage network response to tectonic or climatic perturbations. Using as a test case a data set of 18 knickpoints that materialize the migration of a 0.7-Ma-old erosion wave in the Ourthe catchment of northern Ardennes (western Europe), we explore the impact of various data fitting on the calibration of the stream power model of river incision, from which a simple knickpoint celerity equation is derived. Our results show that statistical least squares adjustments (or misfit functions) based either on the streamwise distances between observed and modeled knickpoint positions at time t or on differences between observed and modeled time at the actual knickpoint locations yield significantly different values for the m and K parameters of the model. As there is no physical reason to prefer one of these approaches, an intermediate least-rectangles adjustment might at first glance appear as the best compromise. However, the statistics of the analysis of 200 sets of synthetic knickpoints generated in the Ourthe catchment indicate that the timebased adjustment is the most capable of getting close to the true parameter values. Moreover, this fitting method leads in all cases to an m value lower than that obtained from the classical distance adjustment (for example, 0.75 against 0.86 for the real case of the Ourthe catchment), corresponding to an increase in the non-linear character of the dependence of knickpoint celerity on discharge [less ▲]
