Located in the 'inner periphery' of Neapolitan historic center, at the foot of Capodimonte Park, historically the urban fabric of San Carlo Arena district eastern area has developed around two architectural complexes: Santa Maria dei Miracoli and Santa Maria degli Angeli alle Croci, for a long time aggregation places for local people. In addition, the ‘lava dei Vergini’ phenomenon, which periodically flooded the area outside the ancient city walls and the ‘for a via’ street (Via Foria), created optimal conditions for tuff extraction, used for local construction. In the past, physical features, such as the irregularity of the hilly area modeled by natural agents, the presence of several underground quarries, the grandeur of remarkable architectural presence, the numerous alleys in a heavily layered historical fabric, and the peculiarities of the social life that took place beyond Foria, have been a source of inspiration for several and also internationally renowned artists. The original identity of the ancient outer suburb, born from progressive expansions of the neighboring villages outside the city walls, is still marked. The closing elements that caracterize the architecture - in particular building fronts -, reflect its inhabitants attitudes and daily life. In this historic urban landscape 'shred’, this closure - despite the direct proximity to the adjacent old town and several, but not easily accessible, panoramic views of part of Naples Bay - continues to be one of the main identifying characters of the area. Although, for many centuries, this has allowed the 'spirit of places’ conservation, it has been transformed into a voluntary closure against the legality, which led to today serious state of neglect and social decay. Sometimes it is possible to find an excessive and illegal man-soil interaction, and unlawful activities influence and define some features of historical buildings in the area. However, for some years the local population has become aware of the existing problems by operating in a more concrete way, through different kinds of associations and volunteer that try to face the territory needs and emergencies. The goal is the elaboration of an update overview of the existing dynamics in this part of urban tissue and the identification of elements to take into account for possible enhancement perspectives in respect of an identity between invariant and processing factors.

A linear oscillator simultaneously subjected to stochastic forcing and parametric excitation is considered. The time required for this system to evolve from a low initial energy level until a higher energy state for the first time is a random variable. Its expectation satisfies the Pontryagin equation of the problem, which is solved with the asymptotic expansion method developed by Khasminskii. This allowed deriving closed-form expressions for the expected first passage time. A comprehensive parameter analysis of these solutions is performed. Beside identifying the important dimensionless groups governing the problem, it also highlights three important regimes which are called incubation, multiplicative and additive because of their specific features. Those three regimes are discussed with the parameters of the problem. [less ▲]

La démocratie reste un thème chéri par la philosophie politique contemporaine, pour l’écart entre ses théories et ses pratiques, pour la distance critique que ses théories offrent vis-à-vis des régimes démocratiques et de leur évolution, mais aussi parce qu’elle est un objet perpétuel de dissensus entre philosophes, au sujet duquel toute prétention à la véridiction est suspendue à sa réalisation pratique. À ce titre, la transmission de la volonté démocratique est un topos houleux de la philosophie politique contemporaine. Cette question catalyse les concepts pivots des philosophies politiques, la leur poser permet de mieux saisir les enjeux rivaux derrière une terminologie commune à plusieurs auteurs. C’est dans cette démarche que je vous propose d’examiner en miroir les philosophies de Cornélius Castoriadis et de Jacques Rancière. De plus en plus nombreux, des commentateurs rapprochent leurs pensées , qui peuvent s’appuyer sur plusieurs points communs : un attachement au concept de démocratie brandit contre les régimes parlementaires, une opposition contemporaine (quoique depuis des héritages différents) aux thèses défendues par Althusser, et une proximité de sources d’inspirations : la philosophie, le marxisme, et la psychanalyse. Partant de la manière dont cette proximité s’exprime dans la disjonction que chacun opère entre démocratie et science, je tenterai de discerner comment les inflexions qu’ils impriment aux concepts de volonté et d’égalité sous la guise des enjeux de la transmission dessinent des horizons politiques distincts, et dénotent des compréhensions antithétiques – mais indécidables dans la théorie – de ce que peut être la démocratie.

This paper develops a probabilistic decision making framework for reliability management in the short-term operational planning context. We build upon our recent work, which proposed a probabilistic reliability management approach and criterion (RMAC) for the latest decision making opportunity of real-time system operation. Here, we transpose the RMAC to the preceding problem instance of short-term operational planning, wherein i) risk is aggravated by the uncertainty on power injections and weather conditions, and, ii) the problem scope concerns choosing `strategic' actions (e.g., starting additional generating units, granting outage requests for maintenance, etc.) to facilitate decision making during the forthcoming real-time system operation. To anticipate on the latter, we formalize the notion of a real-time `proxy' as a simplified model of the real-time decision making context, adequately accurate for the purpose of operational planning decision making. Stating a first proposal for such a proxy, we mathematically formulate the RMAC for short-term operational planning as a multi-stage stochastic decision making problem and demonstrate its main features by case studies on a modified version of the single area IEEE RTS-96 system.

Humans have the remarkable ability to mentally travel through past and future times. However, while memory for the times of past events has been much investigated, little is known about how imagined future events are temporally located. Using a think-aloud protocol, we found that the temporal location of past and future events is rarely directly accessed, but instead mostly relies on reconstructive and inferential strategies. References to lifetime periods and factual knowledge (about the self, others, and the world) were most frequently used to determine the temporal location of both past and future events. Event details (e.g., places, persons, or weather conditions) were also used, but mainly for past events. Finally, the results showed that events whose temporal location was directly accessed were judged more important for personal goals. Together, these findings shed new light on the mechanisms involved in locating personal events in past and future times. [less ▲]

Our ability to predict the evolution of complex hydrological system is fundamental. For decades, such problems have been solved by calibrating a conceptual model of the subsurface to fit data. Unfortunately, model calibration does not allow a realistic uncertainty quantification, whereas stochastic inversion is often computationally prohibitive. In this contribution, prediction-focused approaches (PFAs) are introduced to overcome those main shortcomings. This new paradigm focused on generating predictions directly from the data instead of generating models. A group of prior models is used to generate the data and the prediction in order to derive a direct relationship between both types of variables. The advantages, limitations and research perspectives are discussed. [less ▲]

Aphids are frequently engaged in mutualistic associations with endosymbionts. Symbionts are bacterial or fungal microorganisms that can be obligate or facultative to aphids. Research showed facultative (or secondary) symbionts have numerous effects on their host aphids such as resistance to heat shock, parasitoids and fungus etc., which may consequently promote a co-evolution between symbionts and hosts. However, this symbiotic relation may be affected by several factors, such as the ability of symbionts to spread from aphids to others within and across populations, and the cost of infections for hosts. Moreover, aphid-symbionts interactions may be affected by aphid living environment such as its host plant, the presence of natural enemies or the temperature. Here we firstly described the functions of nine facultative symbionts (Serratia symbiotica, Hamiltonella defensa, Regiella insecticola, Rickettsia, Rickettsiella, PAXS (pea aphid X-type symbiont), Spiroplasma, Wolbachia and Arsenophonus) studied in aphids one by one, and discussed the associations between these symbionts and aphids, plants and environment. We aim to have a better knowledge of the roles the facultative symbionts play in aphid biology, ecology and evolution, which we believe can provide new inspirations for aphid control. [less ▲]

On connaît la façon dont l’histoire littéraire a narré la geste de la bohème fin de siècle en favorisant les dialogues et recoupements entre les différents groupuscules potaches qui ont émaillé le Paris de l’époque. Pourtant, il y a, dans le même temps, des différences patentes entre les Déliquescences du pseudo-décadent Adoré Floupette (1885) et les signataires de l’Album zutique, confectionné en 1871 mais non-destiné à la publication, de la même façon que les articles du Chat Noir ne répondent pas aux mêmes objectifs que ceux publiés dans les colonnes de L’Hydropathe (1879-1880). L’Hydropathe et Le Chat Noir ont par ailleurs en commun un statut s’apparentant à celui d’une caisse de résonnance : tous deux se construisent dans le prolongement d’un lieu de sociabilité qui les précède et dont ils relatent les spécificités. Société tapageuse plus ou moins organisée d’un côté, cabaret bigarré de l’autre, les espaces pivots à l’origine de ces journaux orientent les préoccupations de ces derniers et peuvent sembler limiter leur marge de manœuvre. La comparaison des logiques de présentation de soi et de réclame permet pourtant d’observer certaines divergences entre les moyens mobilisés par ces deux organes à la fois pour affirmer leur singularité et pour exposer les collectifs qui les élaborent.
