Erratum of initial paper: Postmortem computed tomography angiography vs. conventional autopsy: advantages and inconveniences of each method.

PURPOSE: Postmortem computed tomography angiography (PMCTA) was introduced into forensic investigations a few years ago. It provides reliable images that can be consulted at any time. Conventional autopsy remains the reference standard for defining the cause of death, but provides only limited possibility of a second examination. This study compares these two procedures and discusses findings that can be detected exclusively using each method. MATERIALS AND METHODS: This retrospective study compared radiological reports from PMCTA to reports from conventional autopsy for 50 forensic autopsy cases. Reported findings from autopsy and PMCTA were extracted and compared to each other. PMCTA was performed using a modified heart-lung machine and the oily contrast agent Angiofil® (Fumedica AG, Muri, Switzerland). RESULTS: PMCTA and conventional autopsy would have drawn similar conclusions regarding causes of death. Nearly 60 % of all findings were visualized with both techniques. PMCTA demonstrates a higher sensitivity for identifying skeletal and vascular lesions. However, vascular occlusions due to postmortem blood clots could be falsely assumed to be vascular lesions. In contrast, conventional autopsy does not detect all bone fractures or the exact source of bleeding. Conventional autopsy provides important information about organ morphology and remains the only way to diagnose a vital vascular occlusion with certitude. CONCLUSION: Overall, PMCTA and conventional autopsy provide comparable findings. However, each technique presents advantages and disadvantages for detecting specific findings. To correctly interpret findings and clearly define the indications for PMCTA, these differences must be understood.

“Of Spitzenkandidaten and European Leaders”: Is the new 2014 "politicized” Presidency of the Commission going to be a real step forward in the EU legitimization process?

Thanks to ART.17.7 of the Lisbon Treaty, the European Council now has to “take into account” the results of EP Elections when selecting a candidate for the role of Commission President. The European Parliament has grabbed the opportunity to launch the first electoral race for spitzenkandidaten to the Presidency. Is this the start of a new democratizing (and thus, politicizing) process for the European Union? This dissertation will try to give a possible answer to the dilemma by constructing a comprehensive framework around EP Elections 2014 that will involve both the Commission and the Parliament and an analysis of the debate beyond legal provisions and the possibility of a politicized presidency of the Commission.

Maladie de Whipple: quand y penser [Whipple's disease, when to think about it?].

Whipple's disease is a chronic, systemic, bacterial infection caused by Tropheryma whipplei. Its cardinal symptoms include intermittent and recurrent arthralgia or arthritis together with chronic diarrhoea, abdominal pain and weight loss. It may mimick many chronic inflammatory diseases, and the diagnosis remains a challenge. Salivary and faecal quantitative PCR for T. whipplei should be ensued, if positive, by an upper endoscopy for duodenal biopsies. The treatment consists of a combination of oral doxycycline and hydroxychloroquine for 12 months followed by life-long doxycycline. Whipple's disease, although rare, is an entity that should be considered regularly, as its progression may be fatal if left untreated.

Orthoptic Sequelae Following Conservative Management of Pure Blowout Orbital Fractures: Anecdotal or Clinically Relevant?

The aim of this study was to prospectively assess the prevalence of orthoptic anomalies following conservative management of pure blowout orbital fractures and to evaluate their clinical relevance. Clinical and radiologic data of patients with unilateral conservatively managed pure blowout orbital fractures with a minimum follow-up of 6 months were reviewed. Eligible patients were contacted and invited to undergo an extended ophthalmologic examination as follows: distance and near visual acuities, Hertel exophthalmometry, corneal light reflex (Hirschberg test), ductions and versions in the 6 cardinal fields of gaze, eye deviation with prisms and alternate cover test in all of the 9-gaze directions with Maddox rod, degrees of incyclo/excyclotorsion with right and left eye fixation, horizontal and vertical deviation with Hess-Weiss coordimetry, degree of horizontal/vertical and incyclo/excyclotorsion deviation with Harms wall deviometry, and vertical deviation with Bielschowsky head-tilt test. Of the 69 patients contacted, 49 declined to participate given that they were asymptomatic. Twenty patients agreed to undergo the examination. One patient complained of minimal double vision limited to the extreme downgaze. Four patients had asymptomatic ocular motility disturbances limited to the extreme gaze. Seven patients had asymptomatic horizontal heterophoria. These disturbances did not interfere with daily or professional activities in any of the patients. The current study demonstrated that conservative management of pure orbital blowout fractures can result in orthoptic anomalies. These sequelae were restricted to a very limited portion of the binocular field of the vision and were not found to be clinically relevant.

Pose-based SLAM with probabilistic scan matching algorithm using a mechanical scanned imaging sonar

This paper proposes a pose-based algorithm to solve the full SLAM problem for an autonomous underwater vehicle (AUV), navigating in an unknown and possibly unstructured environment. The technique incorporate probabilistic scan matching with range scans gathered from a mechanical scanning imaging sonar (MSIS) and the robot dead-reckoning displacements estimated from a Doppler velocity log (DVL) and a motion reference unit (MRU). The proposed method utilizes two extended Kalman filters (EKF). The first, estimates the local path travelled by the robot while grabbing the scan as well as its uncertainty and provides position estimates for correcting the distortions that the vehicle motion produces in the acoustic images. The second is an augment state EKF that estimates and keeps the registered scans poses. The raw data from the sensors are processed and fused in-line. No priory structural information or initial pose are considered. The algorithm has been tested on an AUV guided along a 600 m path within a marina environment, showing the viability of the proposed approach

Fragmentation of massive dense cores down to <~ 1000 AU: relation between fragmentation and density structure

In order to shed light on the main physical processes controlling fragmentation of massive dense cores, we present a uniform study of the density structure of 19 massive dense cores, selected to be at similar evolutionary stages, for which their relative fragmentation level was assessed in a previous work. We inferred the density structure of the 19 cores through a simultaneous fit of the radial intensity profiles at 450 and 850 μm (or 1.2 mm in two cases) and the spectral energy distribution, assuming spherical symmetry and that the density and temperature of the cores decrease with radius following power-laws. Even though the estimated fragmentation level is strictly speaking a lower limit, its relative value is significant and several trends could be explored with our data. We find a weak (inverse) trend of fragmentation level and density power-law index, with steeper density profiles tending to show lower fragmentation, and vice versa. In addition, we find a trend of fragmentation increasing with density within a given radius, which arises from a combination of flat density profile and high central density and is consistent with Jeans fragmentation. We considered the effects of rotational-to-gravitational energy ratio, non-thermal velocity dispersion, and turbulence mode on the density structure of the cores, and found that compressive turbulence seems to yield higher central densities. Finally, a possible explanation for the origin of cores with concentrated density profiles, which are the cores showing no fragmentation, could be related with a strong magnetic field, consistent with the outcome of radiation magnetohydrodynamic simulations.

Preparação de LiNbO3 e LiNbO3:Eu3+ pelo método dos precursores poliméricos

The ferroelectric compound LiNbO3 was prepared by the polymeric precursors method in the polycrystalline form containing different concentrations of Eu3+. The compounds were characterized by X-ray diffraction, vibrational and electronic spectroscopy. Electronic spectroscopy was shown to be sensitive to small concentrations of contaminating phases allowing a good control of the compound purity. The presence of Eu3+ ions leads to the formation of the LiNb3O8 phase in the range of 500 to 800 °C. Above this temperature range LiNbO3 and tetragonal (T') EuNbO4 were obtained.

Empirical welfare analysis: when preferences matter

Fleurbaey and Maniquet have proposed the criteria of conditional equality and of egalitarian equivalence to assess the equity among individuals in an ordinal setting. Empirical applications are rare and only partially consistent with their framework. We propose a new empirical approach that relies on individual preferences, is consistent with the ordinal criteria and enables to compare them with the cardinal criteria. We estimate a utility function that incorporates individual heterogeneous preferences, obtain ordinal measures of well-being and apply conditional equality and egalitarian equivalence. We then propose two cardinal measures of well-being, that are comparable with the ordinal model, to compute Roemer’s and Van de gaer’s criteria. Finally we compare the characteristics of the worst-off displayed by each criterion. We apply this model to a sample of US micro data and obtain that about 18% of the worst-off are not common to all criteria.

En torno al cardenal Don Gil Álvarez de Albornoz y el platero sienés Andrea Petrucci: el relicario de la mano de Santa Lucía y el cáliz de San Segundo

Este artículo trata de la complicada y hasta ahora inédita historia de la llegada a España de dos obras cumbres de la orfebrería sienesa del s. XIV en plata con esmaltes translúcidos: el relicario de la mano de Santa Lucía en la catedral de Toledo y el cáliz de San Segundo en la catedral de Ávila. La importación de estos dos importantísimos objetos devocionales y litúrgicos, ambos firmados por el platero sienés Andrea Petrucci, está relacionada con la estancia en Italia del cardenal don Gil de Albornoz, arzobispo de Toledo y posteriormente cardenal de San Clemente y Santa Sabina y legado papal. El mecenazgo del cardenal castellano y de su círculo en Italia explica la comisión y adquisición de estas piezas, cuyos accidentados itinerarios desembocarían finalmente en Toledo y en Ávila.

Dell'arcano del mare / Robert Dudley (junior) Earl of Warwick and Leicester, Duke of Northumberland

Sir Robert Dudleyn arvokas karttateos Dell´Arcano del Mare, osat I-III, on varhaisin koko maapallon kattava merikartasto. Se on myös ensimmäinen merikartasto, joka on laadittu Mercatorin projektion mukaan. Kartastoon on koottu yhteen kaikki silloinen tietämys merenkulusta. Se sisältää merenkulun ja navigoinnin teoriaa, laivanrakennusta ja astronomiaa käsittelevät tekstiosuudet, 145 merikarttaa sekä 180 kuvaliitettä, joiden tekijänä on tunnettu kaivertaja Antonio Francesco Lucini. Kaiverrukset, joiden tekemiseen Lucini oli käyttänyt 12 vuotta, ovat poikkeuksellisen hienolaatuisia, kuten teoksen muukin painotyö. Dudleyn kartasto kuuluu Kansalliskirjaston A. E. Nordenskiöldin karttojen ja kartografisen kirjallisuuden kokoelmaan, joka on liitetty ainoana suomalaisena kohteena Unescon Memory of the World –rekisteriin.

AU COMMENCEMENT ÉTAIT LA MÉTAPHORE: UNE INTUITION PRÉCOCE DE NIETZSCHE SUR LA PRIMAUTÉ DE LA MÉTAPHORE COMME MATRICE COGNITIVE

RÉSUMÉ Cette étude met en perspective le précédent constitué par les travaux précoces du jeune Nietzsche où ce dernier fait valoir la force structurante de la métaphore comme matrice des facultés cognitives. Nous offrons d’abord une brève esquisse des postulats et des acquis des grammaires cognitives associées aux travaux d’Eleanor Rosch, ensuite de George Lakoff et Mark Johnson, ainsi qu’à la notion d’inscription corporelle de l’esprit développée par Francesco Varela. Cet exercice sert de propédeutique à une série de lectures tangentes mobilisant divers angles d’approche appelés à faciliter noter évaluation des contributions de Nietzsche au domaine de la cognition. Les travaux examinés nous situent dans la période contemporaine de la publication de son premier grand ouvrage, La naissance de la tragédie (1872) : les notes pour le cours intitulé Présentation de la rhétorique ancienne (Darstellung der antiken Rhetorik), prononcé au semestre d’hiver 1872-1873 à l’Université de Bâle, ensuite ses Theoretische Studien, datant de l’été 1873, avec un renvoi aux développements plus tardifs dans le Gai Savoir (1882). La thèse de Nietzsche peut être résumée comme suit : tous les éléments de l’appareil catégorial et du régime conceptuel à l’aide desquels nous appréhendons la réalité, a fortiori la notion de vérité qui en est le garant, sont le « précipité » ou le résidu d’un faisceau de métaphores qui constituent la force structurante des facultés cognitives. Si chez Kant nous n’avons accès qu’aux phénomènes et non au noumène, chez Nietzsche nous n’avons affaire qu’à des perspectives ou des points de vues alors que la réalité nous est monnayée sous forme de vérités qui sont des fictions ou des métaphores usées. Il ressort de cet examen que le tropisme endogène de la langue constitue une force majeure dans l’implémentation d’une conceptualité qui a la vertu d’oblitérer sa préhistoire et de se ménager un statut qui est incessamment implosé par le reflux de l’imagination créatrice nourrie par la force métaphorique qui répond à une impulsion foncière que Nietzsche associe à une « force artiste » (Kunstkraft) qui tend à démultiplier les perspectives dont la généalogie se conjugue à l’exponentiel.
