In the Italian public debate, the Mediterranean has represented a discursive formation employed to describe the South as the Other of the North. It has been associated with ‘soft’ representations of cultural order and ‘hard’ discourses of civicness that identify the South along a specific set of sociocultural elements, moral norms and forms of civic organization. The Italian city of Naples holds much empirical evidence as an originator of such Mediterranean discursive formation. Since the early 1990s, singer-songwriters and musicians have attempted to transform this discursive formation and to popularize a positive idea of Mediterraneaness on a cultural, ethnic and political dimension. The aim of this article is to explore this process through musical and ethnographic sources. Neapolitan artists Eugenio Bennato, Almamegretta and 99 Posse provide the case studies. [less ▲]

Changing dynamics of power systems caused by the migration from conventional to distributed energy sources increase the risk of blackouts due to voltage instability, especially in case of unforeseen network conditions (e.g., (N-k)-cases). To enable a both secure and efficient power supply, novel monitoring and emergency control systems for the identification of voltage emergency situations as well as the execution of control actions are required that react reliably in due time and adaptively in case of changing network situations. This paper presents a distributed agent-based approach to counteract voltage instability that is based solely on local measurements and limited inter-agent communication. Distributed agents located at substations in the (sub-)transmission network monitor distribution and transmission voltages as well as load tap changer positions and are able to autonomously curtail load in case system stability is endangered. The applicability of the approach is demonstrated in a co-simulation environment interfacing the multi-agent system with a dynamic power system simulation. The presented approach allows for an early detection of voltage instability as well as a coordinated execution of available control actions. [less ▲]

The paper describes the factors influencing the interplay of pension and tax policies from a fiscal and welfare perspective, and identifies areas where both topics can materially impact one another. The paper also explores the arguments for coordination between income tax and pension policies in light of the distributional and behavioral synergies. The paper raises questions regarding tax policy’s effectiveness for materially influencing pension coverage, contribution compliance, and labor mobility. The authors argue for taxing pension similarly to all other incomes and for limiting tax treatment of mandatory pensions, and for initiating coordinated tax and pension reforms before electoral demographics render such reforms even more difficult than today.

One of the main consequences of the Roman conquest was the diffusion of the Latin language and of Roman culture throughout the conquered countries. According to many texts of the imperial period, Latin became a universal language during the Imperium Romanum. But what is the reality? Did Rome develop any linguistic policies? There is some evidence to show that Rome’s response regarding the sociolinguistic problems that arose under its rule was to be flexible and willing to adapt to the specific requirements of each situation. Under the Republic and the early Principate, there was, in fact, a great flexibility in language use by the Romans in their dealings with the Greek world. Even though Latin-Greek bilingualism was widespread among the Romans of the Republic and the early Principate, in the public context, Latin maintained a high-level role because it represented the language of Rome’s power. In spite of this flexible approach to language use, a natural competition developed between the language of the dominant and the language of the dominated. In the Occident, Latin became the only vehicle of communication, both oral and written, whereas in the Orient, one notes a paradoxical situation: the Hellenization of the Romans due to the high cultural position of the Greek language. However, this dichotomy did not produce a division of the Roman Empire into two impenetrable parts, closed to mutual linguistic and cultural influences, but rather, it generated a more complicated situation, especially in the Oriental part of the Empire. It is this situation that will be analyzed in the present paper. [less ▲]

In this work, the elastic response of unidirectional fiber (UD) reinforced composites is studied in a stochastic multiscale way. First, the micro-structure of UD carbon fiber reinforced composites is statistically studied based on SEM images of its cross-section and an algorithm to generate numerical micro-structures with an equivalent random distribution of fibers is developed. In particular, based on the images spatial analysis, the empirical statistical descriptors are considered as dependent variables and represented using the copula framework, allowing generating micro-structure realizations used as Stochastic Volume Elements (SVEs). Second, a stochastic scale transition is conducted through the homogenization of SVEs. With a view to the use of the resulting meso-scale random field in structural stochastic analyzes, the homogenization is performed in two steps in order to respect the statistical content from the micro-meter-long SVEs to the millimeter-long structural finite elements. To this end, the computational homogenization is applied in a hierarchy model: i) Micro-structure generator produces Small SVEs (SSVEs) which are homogenized; ii) Big SVEs (BSVEs) are constructed from the SSVEs. Finally, it is shown on simple illustrative examples that the scatter of the (homogenized) stress distribution in a composite ply can be simulated by means of the developed methodology. [less ▲]

This paper reviews the state-of-the-art methods to perform structural optimization of flexible mechanisms. These methods are based on a system-based approach, i.e. the formulation of the design problem incorporates the time response of the mechanism that is obtained from a dynamic simulation of the flexible multibody system. The system-based approach aims at considering as precisely as possible the effects of nonlinear dynamic loading under various operating conditions. Also, the optimization process enhances most existing studies which are limited to (quasi-) static or frequency domain loading conditions. This paper briefly introduces flexible multibody system dynamics and structural optimization techniques. Afterwards, the two main methods, named the weakly and the fully coupled methods, that couple both disciplines are presented in details and the influence of the multibody system formalism is analyzed. The advantages and drawbacks of both methods are discussed and future possible research areas are mentioned. [less ▲]

Background: Clinical and experimental evidence support a role for inflammation in the development of colorectal cancer, though the mechanisms are not fully understood. Beyond thrombosis and hemostasis, platelets are key actors of inflammation; they also have been involved in cancer. However, whether platelets participate in the link between inflammation and cancer is unknown. Objective: To investigate the contribution of platelets and platelet-derived proteins to inflammation-elicited colorectal tumor development. Methods: We used a clinically relevant mouse model of colitis-associated cancer. Platelet secretion and their reactivity to thrombin were assessed at each stage of carcinogenesis. We conducted an unbiased proteomic analysis of releasates of platelets isolated at pre-tumoral stage to identify soluble factors that might act on tumor development. Plasma levels of the identified proteins were measured during the course of carcinogenesis. We then treated the mice with clopidogrel to efficiently inhibit platelet release reaction. Results: At pre-tumoral stage, hyperactive platelets were a major source of circulating pro-tumoral serum amyloid A (SAA) proteins. Clopidogrel prevented the early elevation of plasma SAA, decreased colitis severity, and delayed the formation of dysplastic lesions and adenocarcinoma. Platelet inhibition hindered the expansion and function of immunosuppressive myeloid cells as well as their infiltration in tumors, while tissue CD8 T cells were augmented. Platelets or releasates of platelets from cancer mice both were able to polarize myeloid cells toward an immunosuppressive phenotype. Conclusions: Thus, platelets promote initiation of colitis-associated cancer by enhancing myeloid cell dependent immunosuppression. Antiplatelet agents may help prevent inflammation-elicited carcinogenesis by restoring antitumor immunity. [less ▲]

The vector vortex is a coronagraphic imaging mode of the recently commissioned Subaru Coronagraphic Extreme-Adaptive Optics (SCExAO) platform on the 8-m Subaru Telescope. This multi-purpose high-contrast visible and near-infrared (R- to K-band) instrument is not only intended to serve as a VLT-class "planet-imager" instrument in the Northern hemisphere, but also to operate as a technology demonstration testbed ahead of the ELTs-era, with a particular emphasis on small inner-working angle (IWA) coronagraphic capabilities. The given priority to small-IWA imaging led to the early design choice to incorporate focal-plane phase-mask coronagraphs. In this context, a test H-band vector vortex liquid crystal polymer waveplate was provided to SCExAO, to allow a one-to-one comparison of different small-IWA techniques on the same telescope instrument, before considering further steps. Here we present a detailed overview of the vector vortex coronagraph, from its installation and performances on the SCExAO optical bench, to the on-sky results in the extreme AO regime, as of late 2016/early 2017. To this purpose, we also provide a few recent on-sky imaging examples, notably high-contrast ADI detection of the planetary-mass companion \kappa Andromedae b, with a signal-to-noise ratio above 100 reached in less than 10 mn exposure time.

Among the stamp seals from the Ville II of Mari (EDIII - Early Akkad periods) published by D. Beyer in 2007, several are inscribed. Improvements in the reading of owner’s name and / or the layout of the decor can be proposed for some stamps seals discovered in the “chantier H” and “chantier F”. Firstly, a new view of the decor of the cylinder-seal owned by the wife of the "EN of Mari", documented by stamps from the “chantier H”, will be considered. Then, for some of “servant of the girl” known by stamps also discovered in the “chantier H”, this article will propose new reading of their names. Finally, it is now possible to identify the name and function of the owner of the cylinder-seal documented by the only sealing discovered in the “chantier F” from the Ville II. [less ▲]

Context. Post-processing algorithms play a key role in pushing the detection limits of high-contrast imaging (HCI) instruments. State-of-the-art image processing approaches for HCI enable the production of science-ready images relying on unsupervised learning techniques, such as low-rank approximations, for generating a model point spread function (PSF) and subtracting the residual starlight and speckle noise. Aims. In order to maximize the detection rate of HCI instruments and survey campaigns, advanced algorithms with higher sensitivities to faint companions are needed, especially for the speckle-dominated innermost region of the images. Methods. We propose a reformulation of the exoplanet detection task (for ADI sequences) that builds on well-established machine learning techniques to take HCI post-processing from an unsupervised to a supervised learning context. In this new framework, we present algorithmic solutions using two different discriminative models: SODIRF (random forests) and SODINN (neural networks). We test these algorithms on real ADI datasets from VLT/NACO and VLT/SPHERE HCI instruments. We then assess their performances by injecting fake companions and using receiver operating characteristic analysis. This is done in comparison with state-of-the-art ADI algorithms, such as ADI principal component analysis (ADI-PCA). Results. This study shows the improved sensitivity versus specificity trade-off of the proposed supervised detection approach. At the diffraction limit, SODINN improves the true positive rate by a factor ranging from ∼2 to ∼10 (depending on the dataset and angular separation) with respect to ADI-PCA when working at the same false-positive level. Conclusions. The proposed supervised detection framework outperforms state-of-the-art techniques in the task of discriminating planet signal from speckles. In addition, it offers the possibility of re-processing existing HCI databases to maximize their scientific return and potentially improve the demographics of directly imaged exoplanets. [less ▲]
