We report bulk gas concentrations of O2, N2 and Ar, as well as their transport coefficients, in natural landfast subarctic sea ice in southwest Greenland. The observed bulk ice gas composition was 27.5% O2, 71.4% N2 and 1.09% Ar. Most previous studies suggest that convective transport is the main driver of gas displacement in sea ice and have neglected diffusion processes. According to our data, brines were stratified within the ice, so that no convective transport could occur within the brine system. Therefore, diffusive transport was the main driver of gas migration. By analysing the temporal evolution of an internal gas peak within the ice, we deduced the bulk gas transport coefficients for oxygen (DO2), argon (DAr) and nitrogen (DN222 ). The values fit to the few existing estimates from experimental work, and are close to the diffusivity values in water (10-5 cm2 s-124 ). We suggest that gas bubbles escaping from the brine to the atmosphere - as the ice gets more permeable during melt could be responsible for the previously reported high transport coefficients. These results underline that when there is no convective transport within the sea ice, the transport of gas by diffusion through the brines, either in the liquid or gaseous phases, is a major factor in controlling the ocean–atmosphere exchange.

This book provides a cultural and social history of the rise and legitimation of the concept of dynastic continuity in the early history of the Ptolemaic Empire. The scope of the study is therefore neither to provide a general overview of third-century Ptolemaic history, nor to discuss in detail the administrative and economic structures of the Ptolemaic state. Rather, its purpose is to investigate the ways by which the first Ptolemies negotiated and constructed a representation of their power as a dynastic house aspiring to universal dominion, protected by the gods and legitimately continuing the heritage of the Macedonian and Egyptian monarchies. It is argued that they managed to do so by operating within different socio-cultural and ethnic milieus and by pursuing their strategies on a two-fold level: on the one hand, by continuously reshaping the relationship between the present events of the ruling house and its historical and mythical past, so as to adapt it to new political and cultural agendas; on the other hand, by shifting the border between the spheres of human and divine power in order to ensure themselves the legitimacy and loyalty stemming from religious thought and practice. Discussed evidence comprises Greek and Egyptian sources, literary and documentary texts, iconographic and archaeological evidence from the Macedonian conquest of Egypt under Alexander to the ascension of Ptolemy III Euergetes. Whenever possible, a new, encompassing evaluation of old evidence has gained new impetus from the intensive analysis of newly published sources. Secondly, the complex cultural and social factors operating in the construction and legitimation of the Ptolemaic dynasty have been discussed by drawing on the contribution of up-to-date scholarship in cultural and religious history as well as in sociology. The rooting of Ptolemaic power in Egypt and the Eastern Mediterranean is studied as the movement from the immediate but unstable right of conquest established by Alexander, and subsequently claimed by the satrap Ptolemy, to the development of a mature and coherent system of power practices and representations. The structure of the book is meant to provide readers with a chronological and thematic discussion ranging from Alexander’s conquest of Egypt to the first years of Ptolemy III. However, the six chapters that constitute this study can also be read separately as they are conceived as the monographic treatment of major moments or aspects of the cultural, political, and religious history of the early Hellenistic period. Chapter 1 deals with the premises of Ptolemaic power in Egypt by focusing on the time of Alexander’s conquest. The implications of Alexander’s sonship to Zeus Ammon in propaganda and in religion are reviewed by drawing attention to the plurality of audiences (Macedonians, Greeks, Egyptians) for which this motif was conceived and used. Chapter 2 discusses the conflicting patterns of legitimation in the age of the Successors and how Ptolemy exploited them in his rise from satrap to king. Some seminal moments of Ptolemy’s career are re-examined: the acquisition of Alexander’s corpse as a source of embodied legitimacy; the interactions between the leader and pre-existing Macedonian and Egyptian elites as they appear in assembly scenes of Greek historiography and in the hieroglyphic Satrap stele; Ptolemy’s help to the Rhodians against Antigonus and Demetrius and the entanglement between royal charisma and religious honours. Chapter 3 focuses on the figure of Dionysus in Ptolemaic religion and culture from a twofold perspective. Firstly, the chapter provides an innovative analysis of the religious and ideological role of Dionysus in Ptolemy II’s Alexandrian procession described by Callixeinus of Rhodes. Secondly, it aims at offering a contribution for a reappraisal of the figure of Dionysus, of his cults and of the role of his figure within the larger context of the Ptolemaic Empire in the third century BC. Chapter 4 discusses the patterns of divinization of Arsinoe II within the royal couple through the most complete documentary dossier collected thus far on the subject. Rather than constituting the aim of the research, the debate concerning the chronology of Arsinoe’s death and divinization has provided the rough framework for a new investigation of how the image of a solid royal couple was invented and spread in religious life and in propaganda. Diachronic developments in the configurations of the dynastic couple are traced through Greek and Egyptian evidence and discussed in relation to the changing of political agendas during the reign of Ptolemy II. Chapter 5 studies the contribution of Ptolemy III to the construction of Ptolemaic dynastic continuity through old and new evidence, notably by providing fresh observations concerning the recently published decree of Alexandria (243 BC) for the understanding of Ptolemaic royal festivals in general and, more in particular, for the history of the festival Ptolemaia in the second half of the 3rd century BC. Chapter 6 breaks with chronological continuity to trace, through literary and documentary evidence from the Roman period, the development of the tradition envisaging Alexander’s body as a talismanic relic protecting the city of Alexandria. The purpose of this epilogue is to provide a methodological essay of interpretation of cultural traditions in the longue durée, when patterns of continuity developed under the Ptolemies were separated from their original context of diffusion and consequently were re-used to shape the civic identity of Alexandria within the new and broader framework of the Roman Empire. Although focus on the construction of a dynasty as a sequence of legitimate, kindred holders of monarchic power makes Ptolemaic kings and queens the central object of this study, it is argued that sovereigns cannot be considered as the sole holders of the initiative in the political, ideological and religious processes relating to the construction of royal and dynastic imagery. On the contrary, it appears that social agents other than the holders of supreme leadership not only reacted to top-down stimulation, but they also constructed, for their own use, representations of the monarchs that interacted with the message issued by the central power. From this perspective, therefore, dynastic continuity results from the intertextual combination of a variety of ideological and religious motifs stemming from different agents and occasions of communication.

Capgras delusion is characterized by the misidentification of people and by the delusional belief that the misidentified persons have been replaced by impostors, generally perceived as persecutors. Since little is known regarding the neural correlates of Capgras syndrome, the cerebral metabolic pattern of a patient with probable Alzheimer’s disease (AD) and Capgras syndrome was compared with those of 24 healthy elderly subjects and 26 AD patients without delusional syndrome. Compared to the healthy and AD groups, the patient had significant hypometabolism in frontal and posterior midline structures. In light of current neural models of face perception, our patient’s Capgras syndrome may be related to impaired recognition of a familiar face, subserved by the posterior cingulate/precuneus cortex, and impaired reflection about personally relevant knowledge related to a face, subserved by the dorsomedial prefrontal cortex.

Objective: The objective of this paper is to propose, starting from the description of a clinical emblematic case, a theoretical synthesis of the work of phenomenological psychopathology dedicated to melancholia and typus melancholicus (TM), a clinical concept that describes the premorbid personality vulnerable to major depression (“melancholia” for the psychopathological tradition). Method: This is phenomenological analysis of a case study of melancolia, of its premorbid personality and pathogenic triggering situation. We adopt two main phenomenological keys to understanding the develpment of melancholia : role-identity theory and desynchronization theory. The former understands melancholia as a disorder of identity triggered by the loss of the social role with which one has previously over-identifed. The latter sees melancholia as the effect of the desynchronisation from the social environment that further develops into an inhibition of the conative–affective dynamics of life. We present the case of Jonas (64 years old), whose mother (94 years old) recently died. Before his mother’s death, Jonas’ life was entirely orchestrated by the caring for his mother and synchronized in time with this (e.g., he used to go to her house every 4 hours, took all his meals with her, etc.). Jonas, in addition to being hyper-synchronized and hyper-syntonic, fulfills all diagnostic criteria for TM, including “orderliness”, “conscientiousness”, “hyper/heteronomia” and “intolerance of ambiguity”. TM’s attach a disproportioned importance to their social roles (or external representations of identity) at the expense of their own ego-identity. Results: The passage from pre-morbid personality to melancholia is triggered by the death of Jonas’ mother that entails a profound depersonalization. Desynchronization and role loss cause Jonas fall into this severe depersonalization, whose core feature is the feeling of the loss of feeling. Conclusions: This original contribution demonstrates a clinical case can contribute to the construction and refinement of theoretical and conceptual frameworks (like princeps Tellenbach's studies). Over-synchronized tempo and over-identification with social role are emblematically in this case the two sides of the same coin. A parallelism can be established between synchronization (with the mother) and respect for the role at the expense of own identity. The clinical case of Jonas highlights a conceptual bridge between the model of melancholia as loss of social role and the model of melancholia as desynchronization. [less ▲]

Dans le cadre de la littérature de l’exil, il a souvent été question de subjectivités entre-deux, de sujets in-between, et de réflexions entre un « ici » aliénant et un « là-bas » idéalisé. En réaction à cette pensée binaire et suite aux réflexions postcoloniales, les mouvements migratoires sont aujourd’hui célébrés et associés aux figures d’identités composées . Par ailleurs, notre compréhension des migrations a fortement évolué depuis une quinzaine d’années, on ne parle donc plus aujourd’hui de relocalisations unidirectionnelles et permanentes mais plutôt de communauté transnationale et de cultures globalisées selon un agencement postcolonial . C’est dans cette optique que j’observerai quelles sont les différentes masculinités issues de la diaspora dominicaine en confrontation dans le roman de Junot Díaz La Brève et Merveilleuse Vie d’Oscar Wao, et, face à ces tensions de genre, de quelle manière la subjectivité masculine d’Oscar Wao est singulière.

INTRODUCTION: Jumper's knee is a frequent chronic overuse syndrome of the upper part of the patellar tendon. Platelets contain lots of growth factors which could enhance the healing process of tendons. METHODS: Twenty patients with chronic upper patellar tendinopathy were enrolled. Assessments were made before infiltration of PRP, and 6 weeks and 3 months after the infiltration, using a 10--point Visual Analogic Scale, clinical examinations with a pressure algometer, algofunctional scores (IKDC and VISA--P), functional assessments (isokinetic and optojump evaluations) and imagery (ultrasounds and MRI). The PRP was obtained with an apheresis system (COM.TEC, Fresenius). Six millilitres of PRP were injected without local anaesthetic. One week after infiltration, patients started a standardised sub--maximal eccentric reeducation. RESULTS: Pain during daily activities significantly decreased with time. During functional evaluation, it decreased as well, but without significant functional improvement. No improvements in the imagery measurements were observed. Younger patients seemed to be more susceptible to have an improvement of pain by the PRP infiltration. CONCLUSION: This study demonstrates that a local infiltration of PRP associated with a submaximal eccentric protocol can improve symptoms of chronic jumper's knee in patients non--responsive to classical conservative treatments.

This paper proposes a new pixel-based background subtraction technique, applicable to range images, to detect motion. Our method exploits the physical meaning of depth information, which leads to an improved background/foreground segmentation and the instantaneous suppression of ghosts that would appear on color images. In particular, our technique considers certain characteristics of depth measurements, such as failures for certain pixels or the non-uniformity of the spatial distribution of noise in range images, to build an improved pixel-based background model. Experiments show that incorporating specificities related to depth measurements allows us to propose a method whose performance is increased with respect to other state-of-the-art methods. [less ▲]

Diffusion kurtosis imaging (DKI) is a promising extension of diffusion tensor imaging, giving new insights into the white matter microstructure and providing new biomarkers. Given the rapidly increasing number of studies, DKI has a potential to establish itself as a valuable tool in brain diagnostics. However, to become a routine procedure, DKI still needs to be improved in terms of robustness, reliability, and reproducibility. As it requires acquisitions at higher diffusion31 weightings, results are more affected by noise than in diffusion tensor imaging. The lack of standard procedures for post-processing, especially for noise correction, might become a significant obstacle for the use of DKI in clinical routine limiting its application. We considered two noise correction schemes accounting for the noise properties of multichannel phased-array coils, in order to improve the data quality at signal-to-noise ratio (SNR) typical for DKI. The SNR dependence of estimated DKI metrics such as mean kurtosis (MK), mean diffusivity (MD) and fractional anisotropy (FA) is investigated for these noise correction approaches in Monte Carlo simulations and in in vivo human studies. The intra-subject reproducibility is investigated in a single subject study by varying the SNR level and SNR spatial distribution. Then the impact of the noise correction on inter-subject variability is evaluated in a homogeneous sample of 25 healthy volunteers. Results show a strong impact of noise correction on the MK estimate, while the estimation of FA and MD was affected to a lesser extent. Both intra- and inter-subject SNR related variability of the MK estimate is considerably reduced after correction for the noise bias, providing more accurate and reproducible measures. In this work, we have proposed a straightforward method that improves accuracy of DKI metrics. This should contribute to standardization of DKI applications in clinical studies and making valuable inferences in group analysis and longitudinal studies. [less ▲]
