In this paper, numerical and experimental investigations devoted to the evaluation of the bearing resistance of tubular members with gusset plates and through-all long bolts are presented. Unlike lap shear joints, the analysed connection evidences a reduced confinement of the bearing area associated to the use of long bolts and the presence of a gap in the member, which can lead, consequently, to a reduction of the bearing resistance. In order to investigate the behaviour of shear connections made up of thin and thick SHS (Square Hollow Section) profiles and long bolts, an experimental test campaign including 24 specimens and FE simulations have been conducted. Both experimental and FE results have confirmed the influence of local instability on the hole in bearing resistance of thin profiles and the poor accuracy of the available standards for this particular joint typology. In particular, the performed comparisons have shown that, for thin profiles, EC3 model is likely to overestimate the resistance, while for higher thickness of the SHS conservative predictions are obtained. The present paper presents the conducted experimental and numerical investigations, highlighting at the end the need for a proper formulation able to account for the local instability effect on the bearing resistance.

In liberalized network industries, competitors can either compete for service using the existing infrastructure (access) or deploy their own capacity (bypass). We revisit this make-or-buy problem making two contributions to the literature. First we analyze both the profit maximizing behavior of an incumbent and the welfare maximizing behavior when the entrant chooses between access and bypass. Second, we extend the baseline model studied in the literature by allowing for fixed costs of network installation. By analogy to the literature on strategic entry deterrence, we distinguish three regimes of blockaded bypass, deterred bypass and accommodated bypass depending on the entrant's unit cost. We show that the make-or-buy decision of the entrant is not necessarily technologically efficient: when bypass is chosen, it is always the cheapest option but access may be chosen when it is not cost effective.

The synaptic vesicle glycoprotein 2A (SV2A), a protein essential to the proper nervous system function, is found in presynaptic vesicles. Thus, SV2A targeting, using dedicated radiotracers combined with positron emission tomography (PET), allows the assessment of synaptic density in the living brain. The first-in-class fluorinated SV2A specific radioligand, [18F]UCB-H, is now available at high-activity through an efficient radiosynthesis compliant with the current good manufacturing practices (cGMP). We report here a non-invasive method to quantify [18F]UCB-H binding in rat brain with microPET. Validation study in rats confirmed the need of high enantiomeric purity to target SV2A in vivo. We demonstrated the reliability of a population-based input function to quantify SV2A in preclinical microPET setting. Finally, we investigated the in vivo metabolism of [18F]UCB-H and confirmed the negligible amount of radiometabolites in the rat brain. Hence, the in vivo quantification of SV2A using [18F]UCB-H microPET seems a promising tool for the assessment of the synaptic density in the rat brain, and opens the way for longitudinal follow-up in neurodegenerative diseases rodents’ models.

According to Jennifer A. Peeples, the “toxic sublime” refers to “the tensions that arise from recognizing the toxicity of a place, object or situation, while simultaneously appreciating its mystery, magnificence and ability to inspire awe”. As an alternative to the “technological sublime”, which creates awe through the contemplation of human efforts to master the environment, it urges us to consider the negative and noxious aspects of such endeavours. Through her analysis of Edward Burtynsky’s “Manufactured Landscapes”, Peeples introduces a new form of sublime aesthetics, which may also be used as a valuable trope in the study of the relationship between literature and our physical environment. My goal in this study is to extend such considerations to the recent history of American literature, using examples such as Rachel Carson’s “A Fable for Tomorrow” (1962), which describes the invisible “lethal film” made of “systemic insecticides” that converts natural species into carcinogenic poison, thus depicting landscapes as intoxicated “places of beauty” that no longer symbolise human abilities to dominate the environment but rather their lack of control over it. Likewise, in Don DeLillo’s novel White Noise (1985), the protagonist Jack Gladney experiences his daughter’s “utterance” of the car brand “Toyota Celica” as “beautiful and mysterious”, which “str[ikes] [him] with the impact of a moment of splendid transcendence”. Gladney then proceeds to relate his family’s “garbage” to his relatives’ selves as it is a “sign[] of [their] deepest nature”. Jack’s approach to human waste shows that what Cynthia Deitering defines as the “toxic consciousness”—the general awareness of the existence of toxicity in the landscape—is to be associated with the protagonist’s idea of “consumer consciousness”. Indeed, the term toxicity can also metaphorically refer to the “poisoned” nature of our relationship to and perception of specific places, objects, or situations. The viewer in national parks, for instance, tends to see the “sublime landscape” as a “series of picturesque scenes”, which allows him to consume the scene as an “object of artistic consumption”. Such examples point to different but related ways of examining distinct forms of toxicity that characterise our relationship with our physical environment. They also prompt us to examine the problematic nature of technology and progress while dealing with the elusive and paradoxical nature of the technological sublime. [less ▲]

In many applications, and in systems/synthetic biology in particular, it is desirable to compute control policies that force the trajectory of a bistable system from one equilibrium (the initial point) to another equilibrium (the target point), or in other words to solve the switching problem. It was recently shown that, for monotone bistable systems, this problem admits easyto-implement open-loop solutions in terms of temporal pulses (i.e., step functions of fixed length and fixed magnitude). In this paper, we develop this idea further and formulate a problem of convergence to an equilibrium from an arbitrary initial point. We show that this problem can be solved using a static optimization problem in the case of monotone systems. Changing the initial point to an arbitrary state allows to build closed-loop, event-based or open-loop policies for the switching/convergence problems. In our derivations we exploit the Koopman operator, which offers a linear infinite-dimensional representation of an autonomous nonlinear system. One of the main advantages of using the Koopman operator is the powerful computational tools developed for this framework. Besides the presence of numerical solutions, the switching/convergence problem can also serve as a building block for solving more complicated control problems and can potentially be applied to non-monotone systems. We illustrate this argument on the problem of synchronizing cardiac cells by defibrillation. Potentially, our approach can be extended to problems with different parametrizations of control signals since the only fundamental limitation is the finite time application of the control signal.

Le travailleur du futur et la loi A quoi ressemble le travailleur de demain dans un monde où règnent toujours davantage les technologies de l’information ? Cette question est envisagée sous deux angles. Tout d’abord, l’économie numérique a fait naitre de nouvelles formes de production et d’emploi, telles que « l’économie des plateformes » (Uber, Deliveroo, ….). Celle-ci présente divers atouts pour les entreprises et pour les travailleurs, notamment en termes de flexibilité, mais elles est aussi la source de nouvelles formes de travail précaire. Le travailleur de demain est-il un travailleur du numérique sans protection sociale ? Le deuxième angle est celui du travailleur hyperconnecté. Faut-il envisager de créer un droit à la déconnexion ?

Comme les écosystèmes dulçaquicoles, les écosystèmes marins sont soumis à une pression humaine croissante qui altère la qualité de l’eau et les communautés aquatiques. Près de 98 pourcents de l’eau de notre planète bleue est contenue dans les océans qui constituent le réceptacle final de tout ce que nous rejetons comme déchets (volontairement ou non). Moins accessible, les océans sont méconnus, souvent oubliés ou négligés et considérés comme une zone inépuisable et où tout se dilue ; actuellement encore 80% des eaux usées sont rejetées en mer sans traitement préalable, à peine 2 % des surfaces marines sont protégées. La Méditerranée est particulière à plus d’un égard, bassin de concentration, de faible surface (1% des océans) abritant pourtant plus de 10% de la biodiversité mondiale. Cette petite mer est un modèle pour les océanographes : en mesurant ce qui s’y passe, nous pouvons prédire ce que se déroulera à court ou moyen terme dans le reste des océans. Le laboratoire d’Océanologie est activement impliqué depuis une quinzaine d’années dans la mise au point d’indice de la qualité des masses d’eau côtières. Ces indices sont construits sur base des connaissances du milieu (variations naturelles), par la mesure des niveaux de contamination et des effets (observation et contamination en mésocosme) de cette pollution sur les communautés. Nous avons développé et validé des indices biologiques (PREI : Posidonia Rapid and Easy Index, ICAR Indice Caulerpa cylindracea ; espèce envahissante), de pollution (TEPI : Trace Element Pollution Index, TESVI : Trace Element Spatial Variation Index), de qualité paysagère (LIMA LIttoral MArin) … Ces indices sont utilisés actuellement dans le cadre de la DCE (Directive Cadre Eau), la DCSMM (Directive Cadre Stratégie pour le Milieu Marin) et dans des réseaux de surveillance en Méditerranée, ils sont un relais et un moyen de communication entre les scientifiques et les politiques, les gestionnaires. L’exportation et l’apprentissage de l’utilisation de ces indices sont un atout pour une gestion globale de l’eau à l’échelle de la Méditerranée. Leurs applications sur l’ensemble de la façade méditerranéenne ont, entre autre, mis en évidence l’impact positif de l’application de directives européennes en matière de gestion des eaux par rapport aux côtes de Nord de l’Afrique.

Regenerative design holds great promise for a new era of sustainable and positive impact architecture, sparking considerable interest among architects, building professionals and their clients. Until now there are no green buildings with an overall positive impact on environment and health. In this regard, the professional and scientific potential of regenerative architecture can only be fully realized by the setting a design framework that guides designers during projects design, construction and operation. This book introduces readers to key concepts of circularity in the built environment, highlight best practices, introduce opportunities to create value learn from real cutting edge case studies. In this book, we present a novel framework for regenerative building design that can be applied to future constructions based on professional expertise and exposure, towards healthy, resource efficient and green buildings in the AEC industry. We compare four state of the art buildings to address the critical principles, strategies and steps in the transition from the negative impact reduction architecture to the positive impact regenerative architecture, utilizing life cycle analysis. The case studies analysis and comparison can serve as an inspiring eye opener and provide a vision for architects and building professionals in the fields of high performance buildings, resource centered thinking and regenerative architecture.
