One of the bronze plates formerly in the Bianchini collection, which entered the Cabinet des Médailles (Paris) at the end of the 18th century, bears a text and an image, supposedly unintelligible and therefore thought to be of a magic nature. A new examination of this artefact, actually the main part of a bracelet, shows that it depicts an assembly of twenty-eight divinities, illustrating the religious landscape of Egypt in the 2nd-3rd century, and that it is inscribed with two short acclamations. The first one exalts the greatness of the name of Sarapis, the second that of Neôtera the invincible. The identity of this goddess is difficult to define, but she often seems to correspond to a form of Isis assimilated to Korè. The glorifying invocation of these two gods, depicted with their pantheon, may be considered to be an expression of what is today called “megatheism”. [less ▲]

La magie et la sorcellerie des visages comme socle anthropologique de la philosophie sartrienne

L’« émotion » est la possibilité d’une « anthropologie de la relation ». Énoncer une telle proposition nécessite de définir les deux blocs qu’elle relie. Nous réaliserons cette entreprise en recourant à un troisième axe, intermédiaire : celui du visage ou, plutôt, des visages. La thèse de ce court essai tient à considérer que la phénoménologie sartrienne a déjà réalisé ce travail de fond qui requiert, pour le rendre explicite, articulation simple et ordonnancement.

Due to the rapid development of technology, larger data sets concerning activity travel behavior become available. These data sets often lack semantic interpretation. This implies that annotation in terms of activity type and transportation mode is necessary. This paper aims to infer activity types from GPS traces by developing a decision tree-based model. The model only considers activity start times and activity durations. Based on the decision tree classification, a probability distribution and a point prediction model were constructed. The probability matrix describes the probability of each activity type for each class (i.e. combination of activity start time and activity duration). In each class, the point prediction model selects the activity type that has the highest probability. Two types of data were collected in 2006 and 2007 in Flanders, Belgium, i.e. activity travel data and GPS data. The optimal classification tree constructed comprises 18 leaves. Consequently, 18 if-then rules were derived. An accuracy of 74% was achieved when training the tree. The accuracy of the model for the validation set, i.e. 72.5%, shows that overfitting is minimal. When applying the model to the test set, the accuracy was almost 76%. The models indicate the importance of time information in the semantic enrichment process. This study contributes to future data collection in that it enables researchers to directly infer activity types from activity start time and duration information obtained from GPS data. Because no location information is needed, this research can be easily and readily implemented to millions of individual agents. [less ▲]

Aim We report three cases of Landau-Kleffner syndrome (LKS) in children (two females, one male) in whom diagnosis was delayed because the sleep electroencephalography (EEG) was initially normal. Method Case histories including EEG, positron emission tomography findings, and long-term outcome were reviewed. Results Auditory agnosia occurred between the age of 2 years and 3 years 6 months, after a period of normal language development. Initial awake and sleep EEG, recorded weeks to months after the onset of language regression, during a nap period in two cases and during a full night of sleep in the third case, was normal. Repeat EEG between 2 months and 2 years later showed epileptiform discharges during wakefulness and strongly activated by sleep, with a pattern of continuous spike-waves during slow-wave sleep in two patients. Patients were diagnosed with LKS and treated with various antiepileptic regimens, including corticosteroids. One patient in whom EEG became normal on hydrocortisone is making significant recovery. The other two patients did not exhibit a sustained response to treatment and remained severely impaired. Interpretation Sleep EEG may be normal in the early phase of acquired auditory agnosia. EEG should be repeated frequently in individuals in whom a firm clinical diagnosis is made to facilitate early treatment. [less ▲]

Context: OB stars are important in the chemistry and evolution of the Universe, but the sample of targets well understood from an asteroseismological point of view is still too limited to provide feedback on the current evolutionary models. Our study extends this sample with two spectroscopic binary systems. AIMS. Our goal is to provide orbital solutions, fundamental parameters and abundances from disentangled high-resolution high signal-to-noise spectra, as well as to analyse and interpret the variations in the Kepler light curve of these carefully selected targets. This way we continue our efforts to map the instability strips of beta Cep and SPB stars using the combination of high-resolution ground-based spectroscopy and uninterrupted space-based photometry. Methods: We fit Keplerian orbits to radial velocities measured from selected absorption lines of high-resolution spectroscopy using synthetic composite spectra to obtain orbital solutions. We use revised masks to obtain optimal light curves from the original pixel-data from the Kepler satellite, which provided better long term stability compared to the pipeline processed light curves. We use various time-series analysis tools to explore and describe the nature of variations present in the light curve. Results: We find two eccentric double-lined spectroscopic binary systems containing a total of three main sequence B-type stars (and one F-type component) of which at least one in each system exhibits light variations. The light curve analysis (combined with spectroscopy) of the system of two B stars points towards the presence of tidally excited g modes in the primary component. We interpret the variations seen in the second system as classical g mode pulsations driven by the kappa mechanism in the B type primary, and explain the unexpected power in the p mode region as a result of nonlinear resonant mode excitation.

Il est maintenu bien reconnu que le vieillissement cognitif est associé à une diminution des capacités exécutives. Toutefois, si des déficits sont effectivement observés au sein des différentes fonctions, des dissociations entre performances préservées/altérées ont également été observées au sein de chacune. Dans cette revue de question, nous détaillerons les effets du vieillissement dans les fonctions de mise à jour, flexibilité, inhibition et coordination de tâches doubles, ainsi que les modifications au sein des réseaux cérébraux associés à ces processus. Nous discuterons également l'influence des capacités attentionnelles, des ressources en mémoire de travail et de certaines caractéristiques génétiques sur ces modifications. [less ▲]
