We numerically investigate the one-dimensional transport of Bose-Einstein condensates in the context of guided atom lasers using a mean-field description of the condensate in terms of a spatially discretized Gross-Pitaevskii equation. We specifically consider a waveguide configuration in which spatial inhomogeneities and nonvanishing atom-atom interactions are restricted to a spatially localized scattering region of finite extent. We show how the method of smooth exterior complex scaling can be implemented for this particular onfiguration in order to efficiently absorb the outgoing flux within the waveguide. A numerical comparison with the introduction of a complex absorbing potential as well as with the analytically exact elimination of the dynamics of the free non-interacting motion outside the scattering region, giving rise to transparent boundary conditions, clearly confirms the accuracy and efficiency of the smooth exterior complex scaling method.

Oestrogens activate nucleus- and membrane-initiated signalling. Nucleus-initiated events control a wide array of physiological and behavioural responses. These effects generally take place within relatively long periods of time (several hours to days). By contrast, membrane-initiated signalling affects a multitude of cellular functions in a much shorter timeframe (seconds to minutes). However, much less is known about their functional significance. Furthermore, the origin of the oestrogens able to trigger these acute effects is rarely examined. Finally, these two distinct types of oestrogenic actions have often been studied independently such that we do not exactly know how they cooperate to control the same response. The present review presents a synthesis of recent work carried out in our laboratory that aimed to address these issues in the context of the study of male sexual behaviour in Japanese quail, which is a considered as a suitable species for tackling these issues. The first section presents data indicating that 17b-oestradiol, or its membrane impermeable analogues, acutely enhances measures of male sexual motivation but does not affect copulatory behaviour. These effects depend on the activation of membrane-initiated events and local oestrogen production. The second part of this review discusses the regulation of brain oestrogen synthesis through post-translational modifications of the enzyme aromatase. Initially discovered in vitro, these rapid and reversible enzymatic modulations occur in vivo following variations in the social and environment context and therefore provide a mechanism of acute regulation of local oestrogen provision with a spatial and time resolution compatible with the rapid effects observed on male sexual behaviour. Finally, we discuss how these distinct modes of oestrogenic action (membrane- versus nucleus-initiated) acting in different time frames (short- versus long-term) interact to control different components (motivation versus performance) of the same behavioural response and improve reproductive fitness.

As with other writer’s journals, many entries of Borges by Adolfo Bioy Casares are related to spaces in dispute within the literary institution. One of these spaces is the literary import of texts from foreign traditions.

Premature ejaculation (PE) is a disorder characterized by three components: (1) a rapid ejaculation, (2), a feeling of lack of control upon ejaculation, (3) and a distress related to this condition. The criterion of rapidity appears to be most controversial: some authors refer only to subjects’ judgment, while other ones set a maximum ejaculatory latency. Although it focused some criticisms related to a lack of objective latency criteria, the definition of PE propounded by the DSM-IV(-TR) remains most currently used. PE affects about 15 to 30% of the male population. However, the estimations can vary widely depending on populations and methodologies. Several factors contribute to the occurrence of the disorder: one may very probably charge bio-constitutional risks, learning factors, cultural and cognitive influences and the role of anxiety. No robust data allow to implicate personality factors other than anxiety. The influence of the age remains a controversial topic. Cognitive-behavioral techniques appear to be quite efficient in the treatment of PE. However the success rates are variable, and the precise nature of the therapeutic active process remains unclear. Serotonergic drugs and local anesthetics are also efficient, but their action remains strictly symptomatic. The usefulness of phosphodiesterase-5 inhibitors is disputed. Combining psychological and pharmacological approaches might be promising. Unfortunately, there is a lack of clinical trials in this field. Although effective treatments do exist, only a few affected people appear to use them satisfactorily. Efforts have still to be made in order to train adequately heath practitioners and to make the treatments more accessible to the public. [less ▲]

Background: Inflammatory airway disease (IAD) affects performance and well-being in horses. Diagnosis is primarily reached by bronchoalveolar lavage (BAL) cytology but this is invasive and requires sedation. Objectives: The purpose of this study was to identify candidate blood biomarkers of IAD using species-specific expression microarrays. Methods: Horse Gene Expression Microarrays were used to investigate global mRNA expression in circulating leukocytes from healthy and IAD-affected standardbreds and endurance horses. Results: Nine genes were significantly differentially regulated in standardbreds and 61 in endurance horses (P < 0.001). These genes were mainly related to inflammation (eg. ALOX15B, PLA2G12B and PENK), oxidant/antioxidant balance (eg. DUOXA2 and GSTO1-1) and stress (eg. V1aR, GRLF1, Homer-2 and MAOB). DUOXA2, ALOX15B, PLA2G12B, MAOB and GRLF1 variations of expression were further validated by RT-qPCR. The deregulation of the oxidant/antioxidant balance was demonstrated at the protein level by an increase of glutathione peroxidase (GPx) activity in heparinised whole blood of IAD-affected standardbreds (P = 0.0025) and endurance horses (P = 0.0028). There was good correlation (r = 0.7354) between BAL neutrophil percentage and whole blood GPx activity in all horses. Conclusions: There is accumulating evidence that, even when systemic clinical signs are not evident, circulating leukocyte gene expression can reflect responses of other tissues, leading to potential diagnostic applications in the future. Although not specific for IAD, whole blood GPx activity appears to reflect BAL neutrophil percentage. This finding should be further assessed by testing a larger number of horses. [less ▲]

Sans être une revue exhaustive et détaillée de tout ce qui s’est fait et se fait en Belgique francophone en ce qui concerne la formation des enseignants, cet article propose un arrêt sur image permettant de constater ce qui est mis en place en 2013, d'en discuter et de découvrir ce qui se prévoit dans un avenir plus ou moins proche. En s'appuyant sur le discours européen sur la maîtrise des TIC par les enseignants, les auteurs pointent du doigt les différents programmes de formation accessibles aux (futurs) enseignants, que ce soit au cours de leur formation initiale ou dans un cadre de formation continué. Ils envisagent également les formations complémentaires et présentent la seule certification TIC existant à l'heure d'écrire ce texte : form@TICEF. La description qui en est faite met l'accent sur les objectifs annoncés et sur la méthodologie originale qui y est mise en place. Pour compléter le tableau, les différentes initiatives qui naissent actuellement dans le paysage belge sont évoquées, trouvant logiquement leur place parmi les perspectives de la formation en TIC des enseignants. Des constats sont tirés, des réflexions sont amenées, le débat est ouvert. [less ▲]

We show that there exist c-generated algebras (and dense in C^infty([0,1])) every nonzero element of which is a nowhere Gevrey diff erentiable function. This leads to results of dense algebrability (and, therefore, lineability) of functions enjoying this property. In the process of proving these results we also provide a new construction of nowhere Gevrey di fferentiable functions. [less ▲]

Blâmée par Jules Michelet, en raison d'un goût que l'historien du XIXe siècle estime trop prononcé pour les intrigues, Louise de Savoie (1476-1531) est sans conteste l'une des personnalités les plus fascinantes de la première Modernité européenne. Comtesse puis duchesse d'Angoulême, Louise n'est pas seulement la mère de deux illustres enfants, Marguerite et François, futur François Ier. Elle se charge de leur éducation ; une fois son fils devenu le roi de France, elle devient un conseiller des plus influents, avant d'assurer, à deux reprises, la régence du royaume. Amatrice d'art et bibliophile avertie, son action concerne encore la musique, la littérature et l'architecture. Les textes rassemblés dans cet ouvrage - issu d'un colloque tenu, en décembre 2010, à Romorantin-Lanthenay, où Louise possédait le château et des terres sur lesquelles Léonard de Vinci avait projeté d'édifier une ville nouvelle pour la cour - ambitionnent de passer en revue tant les aspects biographiques du personnage, que son action dans le champ politique, religieux et culturel.
