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.

The reign of William IV represents a period concerned with questions of national identity, not only in a national context, but also in a global one. Periodicals of the time, such as the Athenaeum, present the co-existence of two related, but inherently opposite conceptions of literature and its functions: Goethe’s idea of Weltliteratur is contemporaneous to developments in the formation and consolidation of national literatures, which can be observed to co-exist even in the early nineteenth-century. World literature, as imagined by Goethe in the 1930s, represents a way of circumventing the inward-looking attitude of nationalism, and of prioritising fluidity and flexibility over stability. National literature, as practiced widely during the nineteenth century, represents a way of grounding national genius in literary texts, either by scrutinising only the works of authors of a specific nationality, or by comparing them in a transnational, intercultural perspective. This article investigates two series of articles published almost concurrently in the Athenaeum: ‘A Biographical and Critical History of the Literature of the last Fifty Years’, by Allan Cunningham in 1833, and ‘Literature of the Nineteenth Century’, by diverse authors between 1834 and 1838. This article highlights the co-existence between different authorial focalisations in historicising and historiographing literature, demonstrating the malleability, undecidability, and arbitrariness of dominant models of national literary identities. I argue that during the 1830s, the Athenaeum’s outlook is decidedly cosmopolitan and international as the contributors engage with European literature equally often as they do with British texts. They are also eager to stretch the readers’ awareness beyond the European context, embracing the wealth of ideas, styles, and perspectives as culturally enriching, but not exotic, erudition.

This volume explores the literary, cultural, social and political climate in Britain during the reign of William IV (1830–37). Rarely discussed by scholars searching to define the ‘Romantic’ period, and overshadowed by Queen Victoria, William IV’s reign signifies an important moment within the long nineteenth century, one whose literary output is marked by experimentation and generic instability. Rather than simply blurring the boundaries between the Romantic and Victorian periods, this diverse collection of essays demonstrates how the spirit of reform, creative experimentation, and an increasingly politically active middle-class readership produced a peculiar literary and material culture of its own. Responding to a wide range of print culture, including periodicals, albums, graphic satires, novels, poetry, travel writing and guidebooks, by canonical and non-canonical authors, such as Catherine Gore, James Hogg, John Ruskin, Mariana Starke, Thomas Hosmer Shepherd and Thomas Pringle, the essays in this volume map a complex network of conversation, personal and national identities, radical and conservative ideologies, and contested domestic and public spaces, both in Britain and abroad. By addressing various aspects of this remarkable period’s material culture and aesthetic innovations, the essays in this collection complicate our contemporary understanding of the long nineteenth century in Britain and open up new spaces for discussion.

Knowledge Graph-based Core Concept Identification in Learning Resources

in 8th Joint International Conference, JIST 2018, Awaji, Japan, November 26–28, 2018, Proceedings (2018, December)

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 ▲]

Interoperability of EU Databases and Access to Personal Data by National Police Authorities under Article 20 of the Commission Proposals

This contribution assesses data protection concerns relating to the processing of personal data carried out pursuant to Article 20 of the interoperability proposals, which were published by the European Commission on 12 December 2017. The proposals seek to enable all centralised EU databases for security, border and migration management to be interconnected by 2023. Under Article 20 of the proposals, Member States would be permitted to implement national provisions that allow national police authorities to query one of the interoperability components with biometric taken during an identity check. Such queries shall prevent irregular migration and ensure a high level of security within Union. In particular, this article seeks to examine the data protection concerns arising with regard to streamlined law enforcement access to non-law enforcement databases included in the interoperable framework, and addresses risks for individuals to become subject to unfair processing under Article 20 of the interoperability proposal.

Cet ouvrage s’inscrit dans le cadre d’une histoire jeune et très contemporaine, celle d’Internet, du Web et des cultures numériques et explore leur fabrique dans les années 1990 en France. Cette recherche, à la croisée de l’histoire des médias, de l’histoire de l’innovation, et de l’histoire sociale et culturelle, reflète les apports d’une approche française de l’histoire d’Internet et du Web. Matérialité et infrastructures, temporalités et trajectoires, espaces et territoires traversent les cinq chapitres du livre. Ils apportent des arguments au choix d’une analyse nationale d’un phénomène pourtant transnational, en s’intéressant à l’attribution des noms de domaine et à la francophonie au sein de la Toile, à la transition entre la culture Minitel et celle du Web, ou encore à la place d’un État qui passe du volontarisme et du monopole des télécommunications à la dérégulation et aux imaginaires des autoroutes puis de la société de l’information. Explorant les pratiques, difficultés, tâtonnements de la période et le tournant grand public du Web, on croise au cours de cette navigation des informaticiens, des entrepreneurs, des politiques, des passionnés de science-fiction, des militants, autant d’acteurs qui se confrontent, débattent, co-construisent. Ils vous invitent à les suivre dans un chantier entre « cathédrale et bazar », pour reprendre Eric Raymond, dont l’exotisme mais aussi l’actualité des débats ne cessent de nous frapper. Bienvenue dans le Cyberespace des années 1990 ! [less ▲]

The transformation of the European Union’s energy sector poses a number of challenges to the European electricity system. Above all, both the anticipated increase of intermittent electricity from renewable sources and the completion of the internal energy market while guaranteeing a secure supply require an extensive development of electricity infrastructure at the European level. Nevertheless, Europe’s future electricity system entails numerous uncertainties. For example, the definite amount and the location of both electricity generation and consumption are unpredictable. In order to address these ambiguities, the European Network of Transmission System Operators for Electricity (ENTSO-E) develops the two-yearly Ten-Year Network Development Plan (TYNDP). By exploring different plausible future paths using scenarios, the TYNDP aims to identify key infrastructure projects – namely transmission lines and cross-border interconnectors – for the future electricity system. In this capacity, the TYNDP is the central planning tool for European grid infrastructure. This paper explores whether the TYNDP effectively provides a solid planning foundation for future grid investments. For this end, the TYNDPs 2012-2018 are investigated in the light of European energy policies, and their utilization by stakeholders is scrutinized. The paper argues that an existing policy congruence and the strong link to the Projects of Common Interest (PCI) confine the TYNDP solely to the hardware of the electricity system. This in turn profoundly limits the TYNDP’s effectiveness as a strategic planning tool. Hence, a closer connection to the software components of the anticipated European electricity system – namely the future market design and (European) regulations – would further allow for a holistic planning and evaluation of future electricity infrastructure projects.

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 ▲]
