Abstract The Quantified Self Movement, which aims to improve various aspects of life and health through recording and reviewing daily activities and biometrics, is a new and upcoming practice of self monitoring that holds much promise. Now, the most underutilized resource in ambulatory health care, the patient, can participate like never before, and the patient's Quantified Self can be directly monitored and remotely accessed by health care professionals.

La prévention du dépassement (over-reaching) ou tout du moins sa détection précoce est capitale dans le processus d'entrainement compte-tenu de ses effets négatifs sur la performance. L'individualisation de la planification des entrainements rugbystiques et physiques est nécessaire pour ne pas dépasser la charge de travail préalablement identifiée comme optimale pour chaque joueur. En effet, en institutionnalisant les cycles de récupération et de repos relatif, comme nous le réalisions auparavant, la charge réelle n'était pas prise en compte mais bien la charge théorique prévue par la planification. A cette charge de travail du centre de formation, viennent s'ajouter celle du club d'appartenance de chaque joueur mais aussi celle des différentes équipes nationales… Les disparités entre les joueurs en terme de charge de travail et donc de fatigue apparaissent rapidement sans compter les joueurs qui sont blessés et/ou en période de réathlétisation! La difficulté pour nous était d'identifier le moment opportun pour proposer des phases de récupération dans le respect du joueur, de son développement à long terme mais aussi dans notre tâche d'améliorer sa performance.

Après l’avènement des Systèmes d’Information Géographique et l’utilisation de plus en plus répandue des images aériennes et satellitaires, le LiDAR constitue une nouvelle avancée dans la quantification et le monitoring des ressources naturelles en général et forestières en particulier. Le LiDAR est une technologie d’acquisition d’information en trois dimensions. Collectées le plus souvent à partir d’un avion, les données LiDAR prennent la forme de nuages de points plus ou moins denses qui décrivent finement les structures tridimensionnelle des zones observées et donc du couvert végétal dans le cas de zones forestières. Même si, à l'heure actuelle, l’acquisition des données reste encore relativement coûteuse et leur traitement apparemment complexe, les perspectives d’utilisation de ces données apparaissent très prometteuses au plan de la gestion forestière.

Recent developments in router level topology discovery have suggested the introduction of IGMP probing in addition to standard techniques such as traceroute and alias resolution. With a single IGMP probe, one can obtain all multicast interfaces and links of a multicast router. If such a probing is a promising approach, we noticed that IGMP probes are subject to filtering, leading so to the fragmentation of the collected multicast graph into several disjoint connected components. In this paper, we cope with the fragmentation issue. Our contributions are threefold: (i) we experimentally quantify the damages caused by IGMP filtering on collected topologies of large tier-1 ISPs; (ii) using traceroute data, we construct a hybrid graph and estimate how far each IGMP fragment is from each other; (iii) we provide and experimentally evaluate a recursive approach for reconnecting disjoint multicast components. The key idea of the third contribution is to recursively apply alias resolution to reassemble disjoint fragments and, thus, progressively extend the mapping of the targeted ISP. Data presented in the paper, as well as reconstructed topologies, are freely available at http://svnet.u-strasbg.fr/merlin. [less ▲]

Redundant connectivity (or multiconnectivity) between adjacent autonomous systems (ASes) is important for inter-domain traffic engineering and fast recovery in case of failures. However, the redundancy of ASes business relationship links has not been quantitatively studied, mainly due to the difficulty of obtaining relevant data. In this paper, we show that the mrinfo multicast monitoring tool can provide useful data about the Internet topology and such redundant links in particular. Our analysis relies on more than four years of daily queries to about ten thousand routers mapped into more than two hundred ASes. We demonstrate that peering links between ASes are frequently redundant. In particular, our analysis shows that more than half of the studied ASes pairs are connected through multiple physical links. We then refine our analysis by considering the different types of ASes and their business relationships. A particular result of our analysis is that at least 75% of the peer-to-peer relationships between adjacent Tier-1 ASes are redundant, i.e., the con- nections between these ASes involve several physical links. Our analysis is conservative, providing so a lower bound, as some links might not be seen by mrinfo due to ISPs filtering policies. [less ▲]

We normally assess another individual's level of consciousness based on her or his ability to interact with the surrounding environment and communicate. Usually, if we observe purposeful behavior, appropriate responses to sensory inputs, and, above all, appropriate answers to questions, we can be reasonably sure that the person is conscious. However, we know that consciousness can be entirely within the brain, even in the absence of any interaction with the external world; this happens almost every night, while we dream. Yet, to this day, we lack an objective, dependable measure of the level of consciousness that is independent of processing sensory inputs and producing appropriate motor outputs. Theoretically, consciousness is thought to require the joint presence of functional integration and functional differentiation, otherwise defined as brain complexity. Here we review a series of recent studies in which Transcranial Magnetic Stimulation combined with electroencephalography (TMS/EEG) has been employed to quantify brain complexity in wakefulness and during physiological (sleep), pharmacological (anesthesia) and pathological (brain injury) loss of consciousness. These studies invariably show that the complexity of the cortical response to TMS collapses when consciousness is lost during deep sleep, anesthesia and vegetative state following severe brain injury, while it recovers when consciousness resurges in wakefulness, during dreaming, in the minimally conscious state or locked-in syndrome. The present paper will also focus on how this approach may contribute to unveiling the pathophysiology of disorders of consciousness affecting brain-injured patients. Finally, we will underline some crucial methodological aspects concerning TMS/EEG measurements of brain complexity. [less ▲]

The Meuse river basin is shared by five countries. Climate change in the future decades could either lead to a dryer or a wetter situation. In order to build an adaptation strategy that would cope with both scenarios and that is agreed at the international level, water experts have set-up the AMICE project. Quantifying the flood damages is an important part of this project. It required much negotiation at every intermediary step, from the definition of climate scenarios, to the hydraulic modeling and the agreement on damage functions. [less ▲]
