Marks and Epigraphs on Iberian Amphorae. II
2015
Se presenta la segunda parte del repertorio de marcas y epígrafes sobre ánforas ibéricas, con la intención de completar un fenómeno heredero del mundo púnico. Se pretende ir acotando el/los posible/s significado/s de tales marcas, su distribución territorial y su marco cronológico. Las marcas incisas son, en esta ocasión, más numerosas que las impresas y se ha detectado una nueva técnica postcocción (con pintura y carbón) restringida al noreste peninsular. This paper is the second part of the repertoire of marks and epigraphs on Iberian amphorae. The goal is to complete this work, which is related to the Punic world, and know the possible meanings of such marks, their geographical distribut…
Composition et cognition musicales : création, perception, appréciation
2005
Ce texte est un rapport de fin de recherche issu de l'ACI cognitique.; Ce projet avait pour objet d'apporter des éléments objectifs de réflexion sur les possibilités et limites de la perception et de la compréhension des matériaux et des structures d'une oeuvre de musique contemporaine. Les buts spécifiques comprenaient l'étude : 1) des processus d'invention et de résolution de problèmes dans la composition musicale, 2) des processus de traitement perceptif et de mémorisation des matériaux musicaux, 3) du traitement perceptif et mnésique des variations ou transformations opérées sur ces matériaux et de l'intégration des matériaux et de leurs transformations dans une forme d'ensemble, 4) du …
Sphères privée et professionnelle chez les enseignants du premier degré : comment priorisent-ils ?
2019
Private and professional lives among primary teachers: how they prioritize? Being a teacher in primary school seems far from allowing the articulation of work and private life in such a comfortable manner as seen in collective beliefs. In order to deconstruct the belief considering teachers as privileged, this contribution proposes, based on empirical results (an online survey with 21,642 responses), to report, first, how primary teachers prioritize their private or professional lives. Second, this paper highlights the reasons which lead them to favour one of the two fields, notably when priority is given to private life at the expense of professional life. Referring to the issue of work-fa…
Enzyme replacement therapy for mucopolysaccharidosis VI: evaluation of long-term pulmonary function in patients treated with recombinant human N-acet…
2010
Pulmonary function is impaired in untreated mucopolysaccharidosis type VI (MPS VI). Pulmonary function was studied in patients during long-term enzyme replacement therapy (ERT) with recombinant human arylsulfatase B (rhASB; rhN-acetylgalactosamine 4-sulfatase). Pulmonary function tests prior to and for up to 240 weeks of weekly infusions of rhASB at 1 mg/kg were completed in 56 patients during Phase 1/2, Phase 2, Phase 3 and Phase 3 Extension trials of rhASB and the Survey Study. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and, in a subset of patients, maximum voluntary ventilation (MVV), were analyzed as absolute volume in liters. FEV1 and FVC showed little change f…

A Highly Magnetized Twin-Jet Base Pinpoints a Supermassive Black Hole
2016
Supermassive black holes (SMBH) are essential for the production of jets in radio-loud active galactic nuclei (AGN). Theoretical models based on Blandford & Znajek extract the rotational energy from a Kerr black hole, which could be the case for NGC1052, to launch these jets. This requires magnetic fields of the order of $10^3\,$G to $10^4\,$G. We imaged the vicinity of the SMBH of the AGN NGC1052 with the Global Millimetre VLBI Array and found a bright and compact central feature, smaller than 1.9 light days (100 Schwarzschild radii) in radius. Interpreting this as a blend of the unresolved jet bases, we derive the magnetic field at 1 Schwarzschild radius to lie between 200 G and ~8000…
Revising the predictions of inflation for the cosmic microwave background
2009
We point out that, if quantum field renormalization is taken into account and the counterterms are evaluated at the Hubble-radius crossing time or few e-foldings after it, the predictions of slow-roll inflation for both the scalar and the tensorial power spectrum change significantly. This leads to a change in the consistency condition that relates the tensor-to-scalar amplitude ratio with spectral indices. A reexamination of the potentials ϕ2 and ϕ4 shows that both are compatible with five-year WMAP data. Only when the counterterms are evaluated at much larger times beyond the end of inflation does one recover the standard predictions. The alternative predictions presented here may soon co…
Evaporation of Near-Extremal Reissner-Nordström Black Holes
2000
The formation of near-extremal Reissner-Nordstrom black holes in the S-wave approximation can be described, near the event horizon, by an effective solvable model. The corresponding one-loop quantum theory remains solvable and allows to follow analytically the evaporation process which is shown to require an infinite amount of time.
Le Istituzioni di Gaio e il Glücksstern di Niebuhr
2012
Sulla base della documentazione manoscritta, anche inedita, e di altre fonti si ripercorrono le vicende che portarono nel 1816 Barthold Georg Niebuhr a scoprire il palinsesto delle Istituzioni di Gaio nella Biblioteca Capitolare di Verona e si discute criticamente la casualità di tale scoperta.
Der ‚Glücksstern‘ Niebuhrs und die Institutionen des Gaius. Deutsch-italienische Wissenschaftspolitik im frühen 19. Jahrhundert, 2. erweiterte Auflage
2014
In diesem Buch ist die Geschichte der Wiederentdeckung des Palimpsests mit den Gaius-Institutionen durch Barthold Georg Niebuhr neu verhandelt. Die jüngst wiederbelebte These von einer „angekündigten Entdeckung“ wird in Frage gestellt. Das verzerrte Bild des Niebuhrschen Fundes in der Sicht dieser These ist kein Zufall. Es stellt sich vielmehr als später Nachklang wissenschaftlicher Querelen jener Zeit dar. Die These der „angekündigten Entdeckung“ erweist sich bei gründlicher Nachprüfung anhand der Quellen als spekulativ, der Fund ist als eigene Leistung Niebuhrs anzuerkennen. In dieser Abhandlung werden auch bislang unbeachtete oder missverstandene handschriftliche Dokumente textgetreu edi…
