3. Auroral processes at the outer planets - Gérard, Jean-Claude
The mean electron energy may be significantly different in different auroral zones. The Io tail CR is remarkably low in comparison with the high-latitude aurora and independent of its brightness ( ~ 50 keV or less). This is consistent with a model where the tail corresponds to an upward field aligned current closing the magnetospheric circuit in Jupiter’s ionosphere. The CR in the main oval is associated with electron energies from ~50 to several 100 keV. It is statistically positively correlated with the intensity. Brightness increase in the main oval is accompanied by hardening of the electron energy spectrum. This...

7. Aurora B and Cdk1 mediate Wapl activation and release of acetylated cohesin from chromosomes by phosphorylating Sororin - Nishiyama, Tomoko; Sykora, Martina M.; Huis in ’t Veld, Pim J.; Mechtler, Karl; Peters, Jan-Michael
Sister chromatid cohesion depends on Sororin, a protein that stabilizes acetylated cohesin complexes on DNA by antagonizing the cohesin release factor Wings-apart like protein (Wapl). Cohesion is essential for chromosome biorientation but has to be dissolved to enable sister chromatid separation. To achieve this, the majority of cohesin is removed from chromosome arms in prophase and prometaphase in a manner that depends on Wapl and phosphorylation of cohesin’s subunit stromal antigen 2 (SA2), whereas centromeric cohesin is cleaved in metaphase by the protease separase. Here we show that the mitotic kinases Aurora B and Cyclin-dependent kinase 1 (Cdk1) destabilize interactions...

8. Thresholds of gross primary production for the metabolic balance of marine planktonic communities - Duarte, Carlos M.; Regaudie de Gioux, Aurore
The notion that less productive marine planktonic communities tend to be heterotrophic was tested by synthesizing reported estimates of the relationships between the net community production or community respiration and gross primary production (GPP), allowing calculation of the threshold GPP separating less productive, heterotrophic communities from more productive, autotrophic ones. A total of 35 estimates of the threshold GPP were assembled, derived from reports of comparative analyses of individual regions (Mediterranean Sea, Atlantic Ocean, Southern Ocean, Pacific Ocean, and Indian Ocean) and global comparative analyses for open-ocean and coastal environments, time-series analyses of changes in planktonic metabolism at individual locations,...

9. Caracterización y empleo de "conos de sombra" en un laboratorio para calibración neutrónica - Gallego Díaz, Eduardo F.; Valle Díez, Aurora del; Lorente Fillol, Alfredo; Vega-Carrillo, Héctor René; Méndez Villafañe, Roberto; Ibáñez Fernández, Javier
En laboratorios de calibración neutrónica, si las diferencias entre los espectros neutrónicos “en el lugar de trabajo” y los utilizados en la instalación de calibración son muy acusadas, resulta muy complicado obtener factores de normalización adecuados, siendo conveniente tratar de producir campos neutrónicos “realistas”, es decir, cuyo espectro energético sea similar al existente en el lugar de trabajo, lo que permitiría la calibración directa de los instrumentos dosimétricos. Uno de los métodos utilizados, es el método de los “conos de sombra”. En este trabajo se presentan el diseño, caracterización y empleo de los conos de sombra del Laboratorio de medidas...

12. Lignin as a raw material for industrial materials applications - Richel, Aurore; Vanderghem, Caroline; Jacquet, Nicolas; Aguedo, Mario
Native lignin is an abundant biopolymer on earth and represents 15-30% by weight of the lignocellulosic biomass. Lignin is a heterogeneous cross-linked polymer composed of phenylpropane units (guaiacyl, syringyl or p-hydroxyphenyl) linked together by a panel of specific ether or carbon-carbon bonds.[1] Nowadays, large amounts of lignins and lignin-based wastes are available and originate either from the pulp and paper manufacturing or from the production of bioethanol from lignocellulose. [2] Typically, these lignins are dedicated to energetic purposes by combustion. In recent years however, novel axes for high added value applications have emerged and concern, notably, the use of lignin...

13. Les obligations d’information, de renseignement, de mise en garde et de conseil aux entreprises : le cas du juriste d'entreprise - Thirion, Nicolas; Jansen, Aurore
Peer reviewed

14. COMMON Tool - Defays, Aurore; Jeunejean, Aurélie
COMMON Tool is web application that allows to cross multimodal data from observations or experiments. Multimodal data coming from manual or automatic coding are imported in CSV format. This application gives the user the opportunity to observe on a time-line whenever a participant engages a particular mode of communication (such as speech, gesture, gaze, or graphics productions). The main advantage of this time-line is that it allows to dynamically display the data. Indeed, the user can set different display filters according to its criteria and desired outcomes. This software enables the user to perform quantitative analysis on the utilisation of...

16. Acerca de la pérdida de la condición de abolorio de un inmueble por su ingreso en el patrimonio consorcial de un cónyuge pariente y un cónyuge no pariente, y otras cuestiones relativas al derecho de abolorio - López Azcona, María Aurora

17. Algunas tesis sobre el derecho de abolorio (consideraciones sobre la institución a partir de la legislación, doctrina y jurisprudencia ante una eventual reforma) - López Azcona, María Aurora
El presente trabajo recoge las principales conclusiones a las que llegó esta autora en su tesis doctoral, tras no pocos años dedicados al estudio del derecho de abolorio tanto desde su perspectiva histórica como en Derecho vigente, sin olvidar el análisis comparado con otras preferencias adquisitivas familiares que rigen en Derecho español. De tales consideraciones se ha considerado oportuna su difusión en un momento en que previsiblemente se va a proceder a la renovación del régimen jurídico de la institución, a fin de propiciar el oportuno debate en la comunidad jurídica. A tal objeto, tras exponer los principales hitos de su historia legislativa, se analiza la naturaleza jurídica...

19. Aurora B kinase controls the targeting of the Astrin-SKAP complex to bioriented kinetochores - Schmidt, Jens Christopher; Kiyomitsu, Tomomi; Hori, Tetsuya; Backer, Chelsea B.; Fukagawa, Tatsuo; Cheeseman, Iain McPherson
During mitosis, kinetochores play multiple roles to generate interactions with microtubules, and direct chromosome congression, biorientation, error correction, and anaphase segregation. However, it is unclear what changes at the kinetochore facilitate these distinct activities. Here, we describe a complex of the spindle- and kinetochore-associated protein Astrin, the small kinetochore-associated protein (SKAP), and the dynein light chain LC8. Although most dynein-associated proteins localize to unaligned kinetochores in an Aurora B–dependent manner, Astrin, SKAP, and LC8 localization is antagonized by Aurora B such that they target exclusively to bioriented kinetochores. Astrin–SKAP-depleted cells fail to maintain proper chromosome alignment, resulting in a spindle...

20. Influence of solar wind on the Jovian thermosphere. - Yates, JN
We aim to explain the reason why Jupiter's upper atmosphere is hotter than initial theories predicted by employing a coupled magnetosphere, ionosphere and thermosphere model. We use this coupled model to study how changes in upstream solar wind dynamic pressure affect Jupiter's thermospheric dynamics, energy balance, aurora and magnetosphere-ionosphere coupling currents. The variation in solar wind pressure is investigated on long (_50 Jovian days) and short (3 hours) time scales, which we respectively refer to as steady state and transient state. We vary the solar wind pressure by changing the size of the magnetosphere, as these two parameters are inversely...
