Video games have become more and more complex over the past decades. Today, players wander in visually and option- rich environments, and each choice they make, at any given time, can have a combinatorial number of consequences. However, modern artificial intelligence is still usually hard-coded, and as the game environments become increasingly complex, this hard-coding becomes exponentially difficult. Recent research works started to let video game autonomous agents learn instead of being taught, which makes them more intelligent. This contribution falls under this very perspective, as it aims to develop a framework for the generic design of autonomous agents for large-scale video games. We consider a class of games for which expert knowledge is available to define a state quality function that gives how close an agent is from its objective. The decision making policy is based on a confidence measurement on the growth of the state quality function, computed by a supervised learning classification model. Additionally, no stratagems aiming to reduce the action space are used. As a proof of concept, we tested this simple approach on the collectible card game Hearthstone and obtained encouraging results. [less ▲]

Adding mucus to in vitro fermentation models of the large intestine showed that some genera, namely lactobacilli, are dependent on host-microbiota interactions and that they rely on mucosa layers to increase their activity. This study investigates whether this dependence on mucus is substrate-dependent and to which extend other genera are impacted by the presence of mucus. Inulin and cellulose were fermented in vitro by a fecal inoculum from pig in the presence or not of mucin-beads in order to compare fermentation patterns and bacterial communities. Mucins increased final gas production with inulin and shifted short-chain fatty acids molar ratios (P<0.001). QPCR analyses revealed that Lactobacillus spp. and Bifidobacterium spp. decreased with mucins, but Bacteroides spp. increased when inulin was fermented. A more in-depth community analysis indicated that the mucins increased Proteobacteria (0.55 vs. 0.25 %, P=0.013), Verrucomicrobia (5.25 vs. 0.03 %, P=0.032), Ruminococcaceae, Bacteroidaceae, and Akkermansia spp.. Proteobacteria (5.67 vs. 0.55 %, P<0.001) and Lachnospiraceae (33 vs. 10.4 %) were promoted in the mucuscompared to the broth, while Ruminococcaceae decreased. The introduction of mucins affected many microbial genera and fermentation patterns, but from PCA results, the impact of mucus was independent from the fermentation substrate. [less ▲]

In order to favor electronic conductivity in sodium iron fluorophosphate electrodes for lithium- or sodium-ion batteries, composites of Na2FePO4F with multi-walled carbon nanotubes (CNTs) were prepared by pilot-scale spray drying. Addition of multi-walled CNTs in the solution results in an excellent dispersion of the CNTs within the volume of Na2FePO4F and not only at the surface of the particles. Following a heat treatment at 600°C in argon in order to reach crystallization, X-ray diffraction and ex situ Mössbauer spectroscopy revealed the presence of significant amounts of Fe(III) and maghemite (γ-Fe2O3) in the powder. However, Na2FePO4F/CNTs composites exhibit good electrochemical performance when cycling against lithium, with a discharge capacity of 104mAhg-1 at C/10 rate and 90mAhg-1 at 1C rate. Therefore, operando 57Fe transmission Mössbauer spectroscopy analyses were carried out in order to investigate the evolution of the iron oxidation state during cycling. During the first discharge, all the Fe(III) is reduced to Fe(II), explaining the good electrochemical performance. [less ▲]

This chapter presents the modalities of a system of benchmarking that has been designed with the aim of measuring legal protection against statelessness as provided by citizenship laws and comparing these across countries and regions. The benchmarks focus on seven groups of persons who are at risk of remaining/becoming stateless, including otherwise stateless children born in a country and persons who are at risk of being deprived of citizenship. This chapter discusses not just how and why these benchmarks have been developed but also what lessons can be drawn from their application in Europe and the Americas. [less ▲]

It is well-known that the concept of nationality plays an important role in different fields of the law, be it private or public law, private international law (‘conflicts of law’) or public international law. While nationality is also frequently the subject of comparative analysis, and therefore of comparative law, little has so far been written on the conceptual and linguistic difficulties that arise in conducting comparative analyses of the nationality laws of different countries – especially if one does not rely on translations but examines them in the original languages. After giving an overview of the legal scholarship on legal translation and comparative law and assessing its relevance for the domain of nationality law (sections 2 and 3), the paper will continue with some remarks on the usefulness and quality of bi- and multilingual legal dictionaries for these fields of study (section 4). While my own experiences in conducting comparative and multilingual research on nationality law are referred to throughout the paper, section 5 will specifically give relevant examples from my work on the book Nationality Law in the Western Hemisphere: A Study on Grounds for Acquisition and Loss of Citizenship in the Americas and the Caribbean.

A French writer born on North African soil and a pied-noir who opposed both the O.A.S. and the F.L.N., Albert Camus has always enjoyed a problematic status in post-imperial France, a country where the taboos surrounding the Algerian War have been kept alive by left- and right-wingers alike. While on the one hand right-wing French politicians have recurrently appealed to Pied-Noir ‘nostalgéria’ to justify their stubborn stance of non-repentance as regards the 130 years of colonization in Algeria, on the other, influential left-wing figures, such as Pierre Nora, have participated in a climate of intellectual atrophy by joining what British historian Perry Anderson has recently called “union sucrée,” that is, sugar-coated, and self-indulgent, versions of France and its colonial past. The difficult, even impossible, memorialization of Camus and his work in today’s France was evidenced again on the eve of the writer’s centenary. In 2012, the project of a major Camus exhibition in Aix-en-Provence for Marseille-Provence European Capital of Culture 2013 was stalled, following on the brutal eviction of its curator, French Algeria historian Benjamin Stora, by arch-conservative Aix-en-Provence mayor Maryse Joissains-Masini. Certainly, the subsequent absence of official celebrations in France surrounding Camus’ 100th birthday implied that the specificity of Camus’ liberal pied-noir voice would still remain silenced there for quite some time. But it also gave new momentum to U.S. historian Todd Shepard’s suggestion that the all-too-easy conflation of ‘pied-noir’ and ‘right-wing extremist’ (which has been dominant in France since the start of the Fifth Republic, at times correctly so) has helped naturalize the construction of some post-imperial ‘all-good-again’ Frenchness, in particular maintain the comforting belief that the “‘Algerian experience’ had been an unfortunate colonial detour, from which the French Republic had now escaped” (The Invention of Decolonization, 11). Can it be that Camus’s heritage is a “burning” one (cf. Stora’s Camus brûlant (2013)) because the irreconcilability of his work and commitments with the utilitarian image of the pied noir extrémiste would reveal the extent to which today’s France is dependent on this same image to keep the memory of its own involvement in colonialism at bay? This question constitutes the starting point of my discussion of Sandra Smith’s new translation of L’Etranger (2013), which appeared in the same year as two other books also inviting us to reconsider the actuality of Camus’ Algerian legacy from a non-French perspective – namely Kamel Daoud’s Meursault, contre-enquête, a retelling of Camus’ classic which was published in Algeria, and Arthur Goldhammer’s translation, for the first time in English, of Camus’s Algerian Chronicles, which offers the writer’s final word on the Algerian question. Taking my cue from Mona Baker, who argues that “translators […] play a crucial role in both disseminating and contesting public narratives with and across national boundaries” (Translation and Conflict, 4-5), I intend to contextualize Smith’s new translation of Camus’s classic within a broader frame of contemporary attempts at problematizing the strategic pigeonholing of Camus as colonialist, decades after Edward Said’s pronouncement that The Stranger was informed by an “incapacitated colonial sensibility” (Culture and Imperialism, 176). Lawrence Venutti has argued that “the intertextual and interdiscursive relations that a translation establishes are not merely interpretative, but also potentially interrogative” (Translation Changes Everything 182). My hypothesis is that Smith’s translation strategy, which includes the re-humanization of Meursault, creates a web of new meanings that participate in opening a space through which Camus’ anti-hero can be seen both as an outsider and an insider to French Algeria – a space that might reach backward and forward, with a potential for complicating the pieties of post-imperial France.

Progressive refinements of the current sources in magnetic vector potential finite-element (FE) formulations are done with a subproblem method. The sources are first considered through magnetomotive force or Biot–Savart models up to their volume FE models, from statics to dynamics. A novel way to define the source fields is proposed to lighten the computational efforts, through the conversion of the common volume sources to surface sources, without the need for any preresolution. Accuracy improvements can then be obtained for local currents and fields, and global quantities, i.e., inductances, resistances, Joule losses, and forces. [less ▲]

The discretized source magnetic vector potential Aj, projected from source field Hs with H(curl,Ω) semi-norm, is studied for non-meshed coils with magnetic vector potential A and electric scalar potential V formulation. As a novelty, source potential Aj is computed in a reduced domain Ωred instead of the complete domain Ω. For domains with fixed and moving parts, potential Aj can be computed on each part, for each of the related current sources, with no need to ensure its continuity between these parts. [less ▲]

OBJECTIVE: To determine the association between three fibulin-3 peptides and the incidence of radiographic and clinical knee osteoarthritis (OA). DESIGN: Women between 50 and 60 years, with a BMI >/=27 kg/m2, free of knee OA, were recruited. Using binary logistic regression, the association between baseline concentration of serum fibulin (Fib)3-1, Fib3-2 and Fib3-3 and incidence of clinical and radiographic knee OA after 30 months of follow-up was evaluated. RESULTS: Baseline and follow-up measurements were available for 241 women with a mean age of 55.9 +/- 3.2 years and mean BMI of 31.7 +/- 3.6 kg/m2. None of the concentrations of the three Fib3 epitopes were associated with the incidence of medial or lateral joint space narrowing (JSN) >/=1.0 mm or the incidence of Kellgren & Lawrence (K&L) grade >/=2 after 30 months. All three Fib3 epitopes were associated with the incidence of the clinical and radiographic ACR-criteria and Fib3-1 and Fib3-3 also with chronic pain at follow-up. When adjusted for the other Fib3 peptide concentrations, only Fib3-1 was significantly associated to the incidence of the American College of Rheumatology (ACR)-criteria (OR 3.2 [1.2-8.7]) and chronic pain at follow-up (OR 3.0 [1.2-7.7]). CONCLUSIONS: Baseline fibulin-3 concentrations are associated with the incidence of clinical knee OA among middle-aged overweight and obese women. Therewith, they meet the criteria of a prognostic biomarker according to the BIPED biomarker classification for OA. Further validation of the fibulin-3 epitopes seems warranted in order to better distinguish subgroups of individuals at increased risk for knee OA development. [less ▲]
