Age control points and sedimentation rates of ODP Hole 145-887B (Table 1)

Hole 887B of the Ocean Drilling Program (ODP) comprises a 44 m (750 kyr) long continuous section recovered from the Patton-Murray Rise, an elevated plateau that is largely isolated from turbidite deposition. The Patton-Murray area is centered under the Alaska Gyre, a region characterized by the domal upwelling of nutrient-rich waters. Marked increases in productivity and rapid settling of biogenic matter are suggested throughout the section by the episodic accumulation of diatomaceous oozes up to ~1 m thick that are accompanied by barium enrichments. Significant delta13Corg maxima in the major diatomaceous bands suggest that mixedlayer [CO2(aq)] may have been drawn down significantly during some of the productivity events. The episodes of enhanced productivity at Site 887 occur synchronously with short-lived minima in planktonic foram delta18O, suggesting a direct link to low salinity, or less likely, warming, events in the Gulf of Alaska. There is no obvious explanation for the events, but they may be related to seasonal incursions of meltwater from Alaska. We speculate that episodic input of meltwater- or dust-borne iron from Asian or Alaskan sources may have promoted the extraordinary diatom production events recorded in the sedimentary record.

(Table 1) Age control points and of sediment core MD01-2444

The marine isotopic stage 3 (MIS3) at Ocean Drilling Program (ODP) Site 1060 (Gulf Stream) shows both sharp onset and end of interstadials, the existence of very short lived warm events during stadials, and points to differences in detail between the sea surface temperature (SST) record from the western North Atlantic and the atmospheric temperature record inferred from d18O in Greenland ice. Investigating MIS3 and obtaining comparable data from other locations appears crucial. The eastern Atlantic provides well-documented records of climate changes. We have selected a core from off Portugal and use it to examine Dansgaard/Oeschger events (D/O) at centennial-scale resolution (139 years on average between two data points). We have obtained a faunal data set for core MD01-2444, 37°N, 10°W, 2600 m water depth and use a group of species (Globigerina bulloides + Globigerinita glutinata) as a proxy of upwelling intensity driven by trade winds intensity changes. We tentatively relate the variation of this group to a North Atlantic Oscillation-like phenomenon (NAO) off Portugal. We observe that it resembles the rainfall index in the Caribbean as recorded at ODP Site 1002 (Cariaco Basin) which traces the Intertropical Convergence Zone (ITCZ) location through changes of terrigenous inputs. The driest intervals (ITZC to the south) at Site 1002 correspond to intervals of increased upwelling in MD01-2444 as well as the driest periods identified during stadials on similar cores in the area. Because the ITZC to the south is consistent with an El Niño-Southern Oscillation (ENSO+) situation, our study suggests a positive correlation between ENSO-like conditions and NAO-like conditions at a millennial timescale. During interstadial intervals when increased wetness over Cariaco is recorded (ITCZ to the north) and the upwelling in MD01-2444 is decreased, we see from both SSTs and faunal tropical indicators that MD01-2444 site is warm. In addition, interstadials are equally warm through each so-called Bond cycle. This contrasts with the Greenland Ice Core Project (GRIP) record where interstadial peaks are successively cooler through each Bond cycle. This record confirms a link between tropical climate linked to ITCZ position and the climate of southern Europe at millennial timescales, in spite of showing a very good correlation with polar latitudes (GRIP) through d18O on Globigerina bulloides. In addition, because the warmest SSTs and the d18O on G. bulloides are so remarkably different, our work points to changes in seasonality as a strong control over the climatic pattern of the North Atlantic area and the marked influence of winter conditions.

ADCP current profiles and conductivity and temperature collected at two points of Camarinal Sill, Strait of Gibraltar

The present study addresses the hypothesis that the Western Alborán Gyre in the Alborán Sea (the westernmost Mediterranean basin adjacent to the Strait of Gibraltar) influences the composition of the outflow through the Strait of Gibraltar. The process invoked is that strong and well-developed gyres help to evacuate the Western Mediterranean Deep Water from the Alboran basin, thus increasing its presence in the outflow, whereas weak gyres facilitates the outflow of Levantine and other Intermediate waters. To this aim, in situ observations collected at Camarinal (the main) and Espartel (the westernmost) sills of the Strait have been analyzed along with altimetry data, which were employed to obtain a representative proxy of the strength of the gyre. An encouraging correlation of the expected sign was observed between the time series of potential temperature at Espartel sill, which is show to keep information on the outflow composition, and the proxy of the Western Alborán Gyre, which strongly suggests the correctness of the hypothesis, although the weakness of the involved signals does not allow for drawing definitive conclusions.

Caractérisation et optimisation d'un détecteur à scintillation à 2 points

Ce projet de recherche s’inscrit dans le domaine de la dosimétrie à scintillation en radiothérapie, plus précisément en curiethérapie à haut débit de dose (HDR). Lors de ce type de traitement, la dose est délivrée localement, ce qui implique de hauts gradients de dose autour de la source. Le but de ce travail est d’obtenir un détecteur mesurant la dose en 2 points distincts et optimisé pour la mesure de dose en curiethérapie HDR. Pour ce faire, le projet de recherche est séparé en deux études : la caractérisation spectrale du détecteur à 2-points et la caractérisation du système de photodétecteur menant à la mesure de la dose. D’abord, la chaine optique d’un détecteur à scintillation à 2-points est caractérisée à l’aide d’un spectromètre afin de déterminer les composantes scintillantes optimales. Cette étude permet de construire quelques détecteurs à partir des composantes choisies pour ensuite les tester avec le système de photodétecteur multi-point. Le système de photodétecteur est aussi caractérisé de façon à évaluer les limites de sensibilité pour le détecteur 2-points choisi précédemment. L’objectif final est de pouvoir mesurer le débit de dose avec précision et justesse aux deux points de mesure du détecteur multi-point lors d’un traitement de curiethérapie HDR.

Analyse des obstacles et des facilitateurs concernant la participation au travail de personnes présentant un trouble de la personnalité limite : points de vue de différents acteurs clés

Résumé : Problématique : Le trouble de la personnalité limite (TPL) est une condition psychiatrique touchant environ 1 % de la population et 20 % de la clientèle recevant des services en psychiatrie (Gunderson et Links, 2008). L’un des domaines du fonctionnement dans la vie quotidienne le plus touché chez cette population est le travail (Gunderson et al., 2011; Larivière et al., 2010; Zanarini et al., 2012). À notre connaissance, aucune étude n’a décrit de façon approfondie la participation au travail des personnes présentant un TPL. Objectif : L’objectif général de cette étude vise à identifier et à décrire les obstacles, les facilitateurs de même que les solutions possibles de la participation au travail des personnes présentant un TPL selon leur point de vue et celui de leurs intervenants. Méthodologie : Une étude de cas multiples a été utilisée (Yin, 2009). Neuf cas ont été étudiés selon trois contextes socioprofessionnels de la participation au travail : A. Réintégration (personne en invalidité), B. Retour (personne en absence maladie) et C. Maintien au travail. Pour chacun des contextes, trois dyades incluant une personne avec un TPL (âgée de 18 à 55 ans) et son intervenant soutenant la participation au travail ont été interviewées. Résultats: Les résultats qualitatifs (n = 18) ont démontré que la participation au travail des personnes présentant un TPL est influencée par des facteurs individuels (p. ex., la réaction face à la pression et aux relations de travail, la régulation émotionnelle) ainsi que des facteurs liés aux acteurs et procédures des systèmes de l’assurance, organisationnel et de la santé (p. ex., la collaboration et la communication entre les acteurs, l’alliance de travail entre les acteurs et la personne présentant un TPL, les mesures d’accommodement et de soutien naturel dans le milieu de travail). Conclusions et implication clinique : Cette étude met en lumière le défi important et spécifique que représente la participation au travail pour les personnes présentant un TPL. Elle implique des facteurs personnels et environnementaux qui doivent être considérés par tous les acteurs impliqués (les utilisateurs de services, les professionnels de la santé, les assureurs et les employeurs). Les programmes de réadaptation au travail actuels devraient être bonifiés et coordonnés adéquatement avec les thérapies spécialisées afin d’aborder de manière optimale les enjeux liés à la participation au travail des personnes présentant un TPL.

Mobility in vehicular networks with multiple access points to the infrastructure

Nowadays there is a huge evolution in the technological world and in the wireless networks. The electronic devices have more capabilities and resources over the years, which makes the users more and more demanding. The necessity of being connected to the global world leads to the arising of wireless access points in the cities to provide internet access to the people in order to keep the constant interaction with the world. Vehicular networks arise to support safety related applications and to improve the traffic flow in the roads; however, nowadays they are also used to provide entertainment to the users present in the vehicles. The best way to increase the utilization of the vehicular networks is to give to the users what they want: a constant connection to the internet. Despite of all the advances in the vehicular networks, there were several issues to be solved. The presence of dedicated infrastructure to vehicular networks is not wide yet, which leads to the need of using the available Wi-Fi hotspots and the cellular networks as access networks. In order to make all the management of the mobility process and to keep the user’s connection and session active, a mobility protocol is needed. Taking into account the huge number of access points present at the range of a vehicle for example in a city, it will be beneficial to take advantage of all available resources in order to improve all the vehicular network, either to the users and to the operators. The concept of multihoming allows to take advantage of all available resources with multiple simultaneous connections. This dissertation has as objectives the integration of a mobility protocol, the Network-Proxy Mobile IPv6 protocol, with a host-multihoming per packet solution in order to increase the performance of the network by using more resources simultaneously, the support of multi-hop communications, either in IPv6 or IPv4, the capability of providing internet access to the users of the network, and the integration of the developed protocol in the vehicular environment, with the WAVE, Wi-Fi and cellular technologies. The performed tests focused on the multihoming features implemented on this dissertation, and on the IPv4 network access for the normal users. The obtained results show that the multihoming addition to the mobility protocol improves the network performance and provides a better resource management. Also, the results show the correct operation of the developed protocol in a vehicular environment.

Robust Stereo Visual Odometry through a Probabilistic Combination of Points and Line Segments

Most approaches to stereo visual odometry reconstruct the motion based on the tracking of point features along a sequence of images. However, in low-textured scenes it is often difficult to encounter a large set of point features, or it may happen that they are not well distributed over the image, so that the behavior of these algorithms deteriorates. This paper proposes a probabilistic approach to stereo visual odometry based on the combination of both point and line segment that works robustly in a wide variety of scenarios. The camera motion is recovered through non-linear minimization of the projection errors of both point and line segment features. In order to effectively combine both types of features, their associated errors are weighted according to their covariance matrices, computed from the propagation of Gaussian distribution errors in the sensor measurements. The method, of course, is computationally more expensive that using only one type of feature, but still can run in real-time on a standard computer and provides interesting advantages, including a straightforward integration into any probabilistic framework commonly employed in mobile robotics.
