We compute the equivariant K-homology of the classifying space for proper actions, for cocompact 3-dimensional hyperbolic reflection groups. This coincides with the topological K-theory of the reduced C*-algebra associated to the group, via the Baum-Connes conjecture. We show that, for any such reflection group, the associated K-theory groups are torsion-free. This means that we can complete previous computations with rational coefficients to get results with integral coefficients. On the way, we establish an efficient criterion for checking torsion-freeness of K-theory groups, which can be applied far beyond the scope of the present paper. [less ▲]

This chapter seeks to show the value of a relational, practice-oriented approach – what in STS vocabulary is called ‘unpacking black boxes’, or doing a sociology ‘of assemblages’. The chapter examines how this approach can shed light on the hybrid mobilizations of innovators, consumers, users and entrepreneurs – alongside their creations and cultures – that have made the Web the complex socio-technical system it is today.

In this paper, we investigate resource allocation and relay selection in a dual-hop orthogonal frequency division multiplexing (OFDM)-based multi-user network where amplify-and-forward (AF) enabled relays facilitate simultaneous wireless information and power transfer (SWIPT) to the end-users. In this context, we address an optimization problem to maximize the end-users’ sum-rate subjected to transmit power and harvested energy constraints. Furthermore, the problem is formulated for both time-switching (TS) and power-splitting (PS) SWIPT schemes.We aim at optimizing the users’ SWIPT splitting factors as well as sub-carrier–destination assignment, sub-carrier pairing, and relay–destination coupling metrics. This kind of joint evaluation is combinatorial in nature with non-linear structure involving mixed-integer programming. In this vein, we propose a sub-optimal low complex sequential resource distribution (SRD) method to solve the aforementioned problem. The performance of the proposed SRD technique is compared with a semi-random resource allocation and relay selection approach. Simulation results reveal the benefits of the proposed design under several parameter values with various operating conditions to illustrate the efficiency of SWIPT schemes for the proposed techniques.

Despite different recent publications investigating global and lesser-known modernisms, Luxembourg remains a blank spot on the map of modernism studies. To some extent, this is surprising. As Gast Mannes notes in his seminal work Luxemburgische Avantgarde of 2007, the underrepresentation of Luxembourgish authors and artists in the history of high modernism is not altogether justified, due to the fact that »individual authors, partly due to bilingualism, played a special role in the transfer of ideas between France and Germany«—a fact that is little known, both in Luxembourg and abroad. To a similar extent, Luxembourg’s absence from modernism studies is unsurprising. One significant factor is that, for many years, the Luxembourgish public, cultural institutions, and creators have placed more value on works of international renown than on Luxembourgish art and literature. This article argues that understanding the invention, management, and rejection of traditions in parallel to avant-garde works is important as it valorises literary and artistic production that could be categorised as »juste milieu«, as moderately modernist, as significant, even revolutionary, in its context, even if not necessarily so from an international perspective.

The initial setting of fresh concrete is mainly caused by the dissolution of cement grains and the precipitation of calcium-silicate-hydrates during cement hydration. Progressing hydration drives the transition from a dense suspension to a porous solid phase. Fresh mixture of self-compacting concrete (SCC) can be considered as a phase-changing multi-component material and can be described as a continuum at the macro scale, interacting with a set of transport-reaction-diffusion processes which in turn are driven by phenomena at the level of the microstructure. This contribution focuses on a predictive model for the setting of fresh SCC where the liquid-solid phase transition is captured by a phase-field variable using the Ginzburg-Landau type free energy function. Hydration-related chemical reactions together with heat and mass transfer are volume coupled with the mechanical behaviour and determined by the environmental conditions. The weak form of the predictive model is discretised using the finite element method and implemented with the FEniCS computational framework. [less ▲]

The automatic identification of core concepts addressed by a learning resource is an important task in favor of organizing content for educational purposes and for the next generation of learner support systems. We present a set of strategies for core concept identification on the basis of a semantic representation built using the open and available knowledge in the so-called Knowledge Graphs (KGs). Different unsupervised weighting strategies, as well as a supervised method that operates on the semantic representation, were implemented for core concept identification. In order to test the effectiveness of the proposed strategies, a human-expert annotated dataset of 96 learning resources extracted from MOOCs was built. In our experiments, we show the capacity of the semantic representation for the core-concept identification task as well as the superiority of the supervised method. [less ▲]

We synthetized and investigated the anti-leukemic potential of the novel cytostatic bis(4-hydroxycoumarin) derivative OT-55 which complied with the Lipinski's rule of 5 and induced differential toxicity in various chronic myeloid leukemia (CML) cell models. OT-55 triggered ER stress leading to canonical, caspase-dependent apoptosis and release of danger associated molecular patterns. Consequently, OT-55 promoted phagocytosis of OT-55-treated CML cells by both murine and human monocyte-derived macrophages. Moreover, OT-55 inhibited tumor necrosis factor α-induced activation of nuclear factor-кB and produced synergistic effects when used in combination with imatinib to inhibit colony formation in vitro and Bcr-Abl+ patient blast xenograft growth in zebrafish. Furthermore, OT-55 synergized with omacetaxine in imatinib-resistant KBM-5 R cells to inhibit the expression of Mcl-1, triggering apoptosis. In imatinib-resistant K562 R cells, OT-55 triggered necrosis and blocked tumor formation in zebrafish in combination with omacetaxine. [less ▲]

The recent expansion of Islamic banks raises questions on its economic implications. The aim of this paper is to investigate the impact of Islamic banking development on access to credit. We combine data from a unique hand-collected database that covers Islamic banks with firm-level data covering developing and emerging countries over the period of 2006 to 2009. We find that Islamic banking development has overall no impact on credit constraints, while banking development and conventional banking development alleviate obstacles to financing. However Islamic banking development exerts a positive impact on access to credit when conventional banking development is low. Hence we support the view that Islamic banking does not overall alleviate obstacles to financing, but it can act as substitute to conventional banking. [less ▲]

This paper concerns the analysis of the representations of ornamented caves in Jean Rouaud’s work. The study highlights, through strong intertextual relations, the continuum which links the cycles of Jean Rouaud’s creation through this theme, so that it is necessary to go beyond the fascination developed by the author about the prehistorical cave paintings. Then it’s suitable to question the recurrence of the pattern of the ornamented cave in Jean Rouaud’s texts. This work reveals a poetical thought of the writer about emergence of art in Préhistoires (2007); the pictorial art, hidden in the loins of the earth, replaces the tale. La femme promise (2009) also stages an ornamented cave, but this time, it is to think about humanity evolution concerning the beauty and the good. Last, La splendeur escamotée de frère Cheval ou le secret des grottes ornées (2018) traces the passage from a prehistorical cosmogony to author’s poetical metaphysics. [less ▲]

Le retour des ressortissants de pays tiers en séjour irrégulier est l‘un des principaux piliers de la politique de l‘UE en matière de migration et d‘asile. Dans son plan d‘action sur le retour en 2015 et dans sa communication de 2017 relative à une politique de retour plus efficace et la recommandation qui l‘a accompagnée, la Commission a souligné la nécessité d‘une mise en œuvre plus stricte des règles européennes en la matière. Cette note de synthèse présente les principaux résultats de l’étude réalisée en 2017 par le point de contact de l´European Migration Network au Luxembourg intitulée «L’efficacité du retour dans les Etats membres de l’UE: défis et bonnes pratiques dans l’application des règles européennes en matière de retour» ainsi que du rapport synthétique qui en résulte. L’étude se base sur les informations recueillies jusqu’au mois de juillet 2017. Cette note de synthèse vise à analyser l‘impact des règles européennes sur le retour ainsi que sur les politiques et pratiques mises en œuvre dans les différents États membres. Elle présente également la manière dont les normes et procédures européennes ont été interprétées et appliquées au niveau national et, dans la mesure du possible, leur impact sur l‘efficacité du dispositif de retour. Toutefois, une certaine prudence s’impose tant il est difficile d‘établir des liens de causalité entre des mesures politiques spécifiques et le nombre de retours mis en œuvre. [less ▲]
