The COVID-19 pandemic has left its marks in the sports world, forcing the full stop of all sports-related activities in the first half of 2020. Football leagues were suddenly stopped, and each country was hesitating between a relaunch of the competition and a premature ending. Some opted for the latter option and took as the final standing of the season the ranking from the moment the competition got interrupted. This decision has been perceived as unfair, especially by those teams who had remaining matches against easier opponents. In this paper, we introduce a tool to calculate in a fairer way the final standings of domestic leagues that have to stop prematurely: our Probabilistic Final Standing Calculator (PFSC). It is based on a stochastic model taking into account the results of the matches played and simulating the remaining matches, yielding the probabilities for the various possible final rankings. We have compared our PFSC with state-of-the-art prediction models, using previous seasons which we pretend to stop at different points in time. We illustrate our PFSC by showing how a probabilistic ranking of the French Ligue 1 in the stopped 2019–2020 season could have led to alternative, potentially fairer, decisions on the final standing.

Using coupling techniques based on Stein’s method for probability approximation, we revisit classical variance bounding inequalities of Chernoff, Cacoullos, Chen and Klaassen. Our bounds are immediate in any context wherein a Stein identity is available. After providing illustrative examples for a Gaussian and a Gumbel target distribution, our main contributions are new variance bounds in settings where the underlying density function is unknown or intractable. Applications include bounds for analysis of the posterior in Bayesian statistics, bounds for asymptotically Gaussian random variables using zero-biased couplings, and bounds for random variables which are New Better (Worse) than Used in Expectation.

This paper investigates the impact of local traffic pollution on the formation of residential and business districts. While firms benefit from local production externalities, households commute to their workplaces with private vehicles and exert a local pollution externality on the residents living along the urban transport networks. The spatial location of firms and residents endogenously results from the trade-off between the production and pollution externalities and the commuting costs. The analysis shows that in monocentric cities the benefits associated with a fall in per-vehicle pollution are absorbed by rents paid to absentee landlords. When a city includes business and residential districts as well as a district mixing both agents, a lower per-vehicle pollution enlarges the residential districts and shifts the business districts closer to the geographical center of the city. The paper finally studies the optimal city structure. The first-best policies that fully internalize the externalities still foster business agglomeration. [less ▲]

Cancer is one of the leading causes of death worldwide with no efficient cure. Even though the currently existing cancer therapies show promising results in early detected cancers, the treatment of late state cancers and metastases still presents many obstacles. The development of treatment resistance and non-responsive cancer hampers the already time-consuming endeavour of drug development. To overcome these hurdles, researchers started to turn to computational approaches to unravel the mechanisms of cancer in terms of onset, development, resistance mechanism, metastasis, and immune invasion among others. The advent of systems biology came not only with the ability to generate large amounts of data but also novel approaches and techniques to analyse them. For example, metabolic modelling approaches can integrate -omics data into a computational representation of metabolism and reconstruct context-specific metabolic models via model-building algorithm such as FASTCORE (Vlassis et al., 2014), FASTCORMICS (Pacheco et al., 2015), and rFASTCORMICS (Pacheco et al., 2019b). Since then, context-specific metabolic models have gained a large area of application that ranges from understanding basic metabolism of microbes, in silico engineering and optimisation of different bacterial strains to applications in human diseases such as biomarker identification and drug target prediction in several diseases, including cancer. In this thesis, I give an overview on metabolic modelling approaches with a focus on cancer and different methods of drug discovery based on the prediction of in silico targets that enable finding cancer-specific targets to advance personalized medicine. To this end, I have developed a drug prediction workflow that has been successfully used to predict and validate three drugs for repurposing in colorectal cancer using context-specific metabolic models reconstructed via rFASTCORMICS (Pacheco et al., 2019b). Furthermore, we have reconstructed 10 005 context specific models for cancer and its controls to investigate the metabolic differences and rewiring strategies used in cancer. A second application of the workflow for melanoma is currently in progress, several drugs have been predicted for repurposing in melanoma and will be tested in vitro on different melanoma cell lines. Additionally, the most promising drugs will also be tested in combination with current melanoma treatment. [less ▲]

Autonomous formation flight enables new satellite missions for novel applications. The cost and limits of propulsion systems can be overcome if environmental resources are being benefitted of. Currently, atmospheric drag is used in low Earth orbit to this end. Solar radiation pressure, which is of similar order of magnitude as aerodynamic ram pressure, is, however, always neglected. We introduce this force and show that it can be exploited. We demonstrate through simulations that a formation geometry is established quicker if the solar radiation pressure is modeled. [less ▲]

Quand il met en scène, en 2003, aux Ateliers Berthier (Théâtre de l’Odéon, Paris, XVIIème), Phèdre de Jean Racine, Patrice Chéreau revient sur le devant de la scène théâtrale en souhaitant contemporanéiser une œuvre considérée, depuis l’année de sa parution (1677), comme la « quintessence de la tragédie française » . Cette volonté d’inscrire cette pièce dans le présent de la création artistique passe notamment par sa lecture singulière du « Récit de Théramène », lequel narre la mort d’Hippolyte. En effet, Patrice Chéreau entend s’opposer à la tradition littéraire de l’énonciation, sous forme d’hypotypose, par une tierce personne - en l’occurrence Théramène, gouverneur du jeune prince - et proposer ainsi une monstration pleinement assumée du corps ensanglanté, morcelé et déchiqueté du corps d’Hippolyte. Reliquat et objet de tous les désirs, le corps atrophié du jeune prince, autour duquel l’intrigue s’est construite, paraît au vu et au su de tous, acteurs comme spectateurs. À l’égard du texte racinien, ce corps apparaît excessif et en surplus vis-à-vis de l’action scénique. Dès lors, un tel parti pris, en marge de la tradition, mérite d’être interrogé, car il remet entièrement en perspective la question de la bienséance classique. Afin de le démontrer, notre réflexion sera divisée en deux parties. La première s’axera précisément sur la bienséance, caractéristique de l’esthétique classique. Dans le cas de ce récit anthologique, nous verrons que Jean Racine se joue lui-même des codes en se référant davantage à Sénèque qu’à Euripide. Le second temps de notre étude cherchera à appréhender le positionnement radical de Patrice Chéreau face à ces présupposés pour, in fine, tenter de comprendre comment ce metteur en scène rompt avec la doctrine classique et offre, par là même, une vision novatrice et inédite - qui deviendra emblématique - de Phèdre de Jean Racine [less ▲]

While platforms use increasingly sophisticated technology to make content-related decisions that affect public discourse, firms are tight-lipped about exactly how the technologies of content moderation function. The laconic nature of industry disclosure relating to their use of algorithmic content moderation is thoroughly unacceptable, considering that regulators need to understand the platform ecosystem in order to design evidence-based regulations and monitor risks associated with the use of AI in content moderation. This white paper sets out to explain how and why audits, a specific type of transparency measure, should be mandated by law within the four clear principles of independence, access, publicity, and resources. We go on to unpack the types of transparency, and then contextualize audits in this framework while also describing risks and benefits. The white paper concludes with the explanation of the four principles, as they are derived from the previous sections. [less ▲]

We study the phenomenon of quantum friction in a system consisting of a polarizable atom moving at a constant speed parallel to a metallic plate. The metal is described using a charged hydrodynamic model for the electrons. This model featuring long-range interactions is appropriate for a clean metal in a temperature range where scattering due to Coulomb interactions dominates over the scattering of electron by impurities. We find that a quantum friction force between the atom and the metal surface exists even in the absence of intrinsic damping in the metal, but that it only starts once the velocity of the atom exceeds the effective speed of sound in the metal. We argue that this condition can be fulfilled most easily in metals with nearly empty or nearly filled bands. We make quantitative predictions for the friction force to the second and fourth order in the atomic polarizability, and show that the threshold behavior persists to all orders of the perturbation theory.
