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.

Il est possible de modéliser la variation et le changement valenciel à l'aide des structures formelles que nous nommons _polygraphes_. Ces derniers étendent les arbres syntaxiques dépendanciels en autorisant des relations à porter sur d'autres relations. En prenant l'exemple de l'expression prépositionnelle ou non du datif en ancien français et en français moderne (complément des verbes _donner_, _aider_, et _pardonner_), nous montrons comment les polygraphes peuvent être employés pour montrer géométriquement la différence entre une préposition obligatoire et une préposition facultative. Le potentiel de ces structures permet également de visualiser l'évolution et de comparer le comportement des lexèmes. [less ▲]

Cet article interroge la relation entre « publics » et « collectifs » et en propose un modèle de description à caractère phénoménologique. Après un examen des implications politiques des modèles auxquels sont susceptibles de se référer les théories de la réception médiatique, on tente d’élaborer, à partir du travail de Stiegler, de Rancière et de Derrida, une approche de la réception qui permet de décrire à la fois l’émancipation et la domination, cette alternative étant l’un des points de butée des théories de la réception. Le critère déterminant est ici l’adresse, considérée comme la traduction en termes phénoménologiques de l’énonciation. La réception est alors envisagée comme une réponse à une adresse. Cette conception de l’énonciation rend compte de la dimension politique d’une réception médiatique où l’identité sociale est désormais indexée sur notre identité de destinataires de dispositifs médiatique, c’est-à-dire de publics [less ▲]

Occupant tout les deux une position liminale du champ de la bande dessinée, Jochen Gerner et Ilan Manouach se sont, chacun à leur manière, livrés à des expériences réflexives de destruction de l'image en bande dessinée par le détournement. Ainsi, avec ses projets tels que TNT en Amérique, Abstraction (1941-1968), ou Le Panorama du Feu, Jochen Gerner opère par la technique du recouvrement une relecture d'albums classiques et de petits formats populaires, attirant l'attention sur certains motifs graphiques, abstraits ou figuratifs des objets détournés. Plus en phase avec l'héritage situationniste du détournement, Ilan Manouach intervient sur les œuvres appropriées pour en questionner les principes idéologiques : Katz interroge la métaphore animale au cœur de Maus, tandis qu'avec Les Schtroumpfs noirs, il retourne au thème de la représentation en imprimant l'album de Peyo entièrement en cyan. Moins politisé dans Riki fermier, Manouach y fait disparaître les personnages d'un album de Petzi pour ne garder que celui du pélican Riki, suivant un projet d'écriture à contrainte décrit comme « lipogrammatique ». Pour Gerner comme Manouach, la pratique du détournement touche directement à la matérialité de l'objet de bande dessinée, au sens où il y a une intervention physique sur les bandes dessinées détournées – que ce soit par recouvrement, retouche ou réimpression – qui se double d'un maintien du format de l'objet détourné (48 CC, pocket, pamphlet ou roman graphique). Le lecteur se retrouve ainsi face à une dé-familiarisation d'un objet pourtant connu et reconnu dans sa matérialité. Cette expérience conscientise un acte réflexif de destruction : les images d'origine se voient recouvertes de noir, rayées, masquées, retouchées, effacées, défigurées. Tout en étant extrêmement opaque, ce rapport à la matérialité est cependant différent d'autres formes de « graphiation »1 qui attirent l'attention sur une gestuelle physique, sur les traces de la main. Au contraire, comme l'a noté Pedro Moura à propos du travail d'Ilan Manouach, il y a une volonté de se « plac[er] en dehors du domaine de l’expression auctoriale, et même humaine, afin de favoriser l’émergence d’une expression dépersonnalisée »2. Plus proches d'une écriture « non-créative » telle que l'a décrite Kenneth Goldsmith3, ces deux pratiques du détournement mettent en scène une destruction d'images, dont les livres en portent la trace, donnant lieu à une traçabilité différente d'une graphiation qui mettrait en avant la patte graphique du dessinateur. La mesure destructrice de cette acte de détournement se retrouve d'ailleurs en prises avec le dispositif juridique du copyright, comme l'atteste la réaction des ayant-droits à Katz, envoyé au pilon. Face à ces deux formes de destruction (destruction de l'œuvre détourné et, retour du bâton, pilonnage du détournement), MetaKatz s'offre une double portée réflexive qui couvre toute la portée du geste destructeur au cœur du détournement, un acte qui se veut en même temps être une forme d'engendrement, puisqu'il ouvre à de nouveaux dispositifs, à de nouvelles images, et à de nouvelles lectures. Notre chapitre mettra donc en parallèle les œuvres d'Ilan Manouach et de Jochen Gerner afin d'examiner comment la question de la destruction se trouve au cœur du détournement, et de façon plus spécifique, comment celle-ci relève d'un rapport complexe à la matérialité du médium dont nous étudierons les enjeux.

We introduce the concept of constant 2-labelling of a vertex-weighted graph and show how it can be used to obtain perfect weighted coverings. Roughly speaking, a constant 2-labelling of a vertex-weighted graph is a black and white colouring of its vertex set which preserves the sum of the weights of black vertices under some automorphisms. We study constant 2-labellings on four types of vertex-weighted cycles. Our results on cycles allow us to determine (r, a, b)-codes in Z^2 whenever |a−b|>4, r>1 and we give the precise values of a and b. This is a refinement of Axenovich’s theorem proved in 2003.

This paper deals with the derivation of a simplified model of a distribution network hosting dispersed photovoltaic units. The model is aimed at short-term dynamic simulations of a transmission grid in response to large disturbances. In a first step, a generic dynamic model of a photovoltaic unit is proposed, focusing on its interactions with the grid, in particular the controls triggered by voltage disturbances. The model takes into account various present and near-future grid codes. In a second step, a dynamic equivalent is derived accounting for the distribution network, the dispersed photovoltaic units, as well as static and dynamic (motor) loads. This equivalent is of the “grey-box” type and its parameters are tuned in the least-square sense to match the dynamic response of the original, unreduced system. Simulation results are reported on a detailed 913-bus distribution system subject to faults at transmission level. [less ▲]

Access-based services (ABS), which grant customers limited access to goods without any transfer of ownership, are unique technology-based service innovations requiring the substantial involvement and collaboration of customers, without employees’ supervision. Although ABS offer several potential advantages, convincing customers to use them remains challenging. Combining 56 in-depth interviews with supplementary literature, the authors address this challenge by proposing an integrative framework that reflects the (1) barriers that prevent customers from using ABS and (2) practices in which customers engage to attenuate those barriers. The complex, multidimensional barriers relate not only to the service and technology features but also to other customers. Customers can engage in different practices to attenuate perceived barriers and create value, namely, “to distance,” “to manage,” “to elaborate,” “to control,” and “to relate.” Yet they regard these barrier-attenuating practices as necessary sacrifices to use ABS. Complementing suggestions that customers adopt and use ABS to escape the burdens of ownership, the current research reveals that customers actually may confront several “burdens of access.” This research suggests managers who wish to reduce rejection of their innovation could not only overcome customers’ perceived barriers, but also facilitate and reduce the number of practices in which customers engage to attenuate those barriers themselves.

The Büchi-Bruyère theorem states that a multidimensional set of non-negative integers is b-recognizable if and only if it is b-definable. This result is a powerful tool for showing that many properties of b-automatic sequences are decidable. Going a step further, first-order logic can be used to show that many enumeration problems of b-automatic sequences can be described by b-regular sequences. The latter sequences can be viewed as a generalization of b-automatic sequences to integer-valued sequences. These techniques were extended to two wider frameworks: U-recognizable multidimensional sets of non-negative integers and multidimensional beta-recognizable sets of reals. In the second case, real numbers are represented by infinite words, and hence, the notion of beta-recognizability is defined by means of Büchi automata. Again, logic-based characterizations of $U$-recognizable (resp. beta-recognizable) sets allows us to obtain various decidability results. The aim of this chapter is to present a survey of this very active research domain. [less ▲]

This paper offers a reconstruction of Külpe’s theory of cognitive attitudes from the perspective of contemporary debates about cognitive phenomenology. I argue that, like Carl Stumpf at approximately the same time, Külpe endorses two major claims about cognitive experiences. First, cognitive experiences are best described in terms of cognitive acts, functions or attitudes. Second, cognitive attitudes are intransitively conscious in the sense that they are experienced by, or phenomenally manifest to, the subject. I call the combination of those two claims the conscious cognitive attitudes theory—or CCA for short. I introduce Külpe’s version of CCA, briefly present some rationales supporting it, and conclude that, on the whole, CCA is worth serious consideration when it comes to describing cognitive experiences.

This paper investigates the seminal texts on Immediate Constituent Analysis and the associated diagrams. We show that the relations between the whole and its parts, that are typical of current phrase structure trees, were less prominent in the early diagramming efforts than the relationships between units of the same level. This can be observed until the beginning of the 1960’s, including in Chomsky’s Syntactic Structures (1957). We discuss whether such analyses could be said “dependency-based”, according to an attempt to define this term. this term. [less ▲]

Distinct gap features in the nearest protoplanetary disk, TW Hya (distance of 59.5$\pm$0.9 pc), may be signposts of ongoing planet formation. We performed long-exposure thermal infrared coronagraphic imaging observations to search for accreting planets especially within dust gaps previously detected in scattered light and submm-wave thermal emission. Three nights of observations with the Keck/NIRC2 vortex coronagraph in $L^\prime$ (3.4-4.1$\mu$m) did not reveal any statistically significant point sources. We thereby set strict upper limits on the masses of non-accreting planets. In the four most prominent disk gaps at 24, 41, 47, and 88 au, we obtain upper mass limits of 1.6-2.3, 1.1-1.6, 1.1-1.5, and 1.0-1.2 Jupiter masses ($M_J$) assuming an age range of 7-10 Myr for TW Hya. These limits correspond to the contrast at 95\% completeness (true positive fraction of 0.95) with a 1\% chance of a false positive within $1^{\prime\prime}$ of the star. We also approximate an upper limit on the product of planet mass and planetary accretion rate of $M_p\dot{M}\lesssim10^{-8} M_J^2/yr$ implying that any putative $\sim0.1 M_J$ planet, which could be responsible for opening the 24 au gap, is presently accreting at rates insufficient to build up a Jupiter mass within TW Hya's pre-main sequence lifetime.

Shallow reservoirs are often used as sediment traps or storage basins, in which sedimentation depends on the flow pattern: Short rectangular reservoirs reveal a straight jet from inlet to outlet with on both sides identical recirculation zones. In longer reservoirs, the main jet reattaches to the side of the reservoir leading to a small and a large recirculation zone. Previous studies found an empirical geometric relation describing the switch between these two flow patterns. In this study, we demonstrate, with a simple analytical model, that this switch coincides with a maximization of energy dissipation in the shear layer between the main jet and recirculation zones: Short reservoirs dissipate more energy when the flow pattern is symmetric, while longer reservoirs dissipate more energy with an asymmetric pattern. This approach enables to predict the flow patterns without detailed knowledge of small scale processes, potentially useful in the early phase of reservoir design. [less ▲]

Estrogens derived from brain testosterone aromatization (neuro-estrogens) are critical for the activation of male sexual behavior. Their effects on this behavior are typically associated with long-term changes in circulating levels of testosterone and the transcriptional activity of their liganded nuclear receptors. According to this view, neuro-estrogens would prime the neural circuits controlling the long-term expression of behavior, which would then be acutely regulated by neurotransmitter systems conveying information from the social environment. In parallel, neuro-estrogens are also able to produce much faster effects than previously anticipated. Our recent investigations in Japanese quail revealed an interesting dichotomy in the regulation of male sexual behavior by membrane- and nuclear-initiated estrogen signaling providing respectively an acute modulation of sexual motivation and a long-term control of the capacity to display the copulatory sequence. In parallel, a similar dichotomy applies to the regulation of brain aromatase whose expression depends on the transcriptional activity of testosterone metabolites while its enzymatic activity is rapidly regulated in a region- and context-dependent manner. Recent evidences suggest that rapid changes in sexual motivation result from rapid changes in local estrogen production. Together, these data support the idea that the acute regulation of some aspects of male sexual behavior depends not only on classical neurotransmitter systems, but also on rapid and spatially restricted changes in local estrogen availability. The existing literature suggests that this acute regulation by neuro-estrogens of the motivational aspects of behavior could be generalized to other systems such as singing behavior in songbirds.

While it goes undisputed that international criminal tribunals (ICTs) are, in general terms, bound to respect human rights standards, there is no consensus on whether their obligations should be identical in scope to those of national criminal tribunals. Most commentators seem to value the idea of equality in protection for international and domestic defendants alike. Yet, according to others, the human rights obligations of ICTs should be contextualised, that is, adapted to the specificities of international justice – and most critically to the gravity of international crimes. This article seeks to shed some light on this debate. It does so, in particular, by pointing out the intrinsic flexibility of human rights, and by drawing on the practice of the European Court of Human Rights with respect to gravity-based contextualism.
