We revisit the notion of deniability in quantum key exchange (QKE), a topic that remains largely unexplored. In the only work on this subject by Donald Beaver, it is argued that QKE is not necessarily deniable due to an eavesdropping attack that limits key equivocation. We provide more insight into the nature of this attack and how it extends to other constructions such as QKE obtained from uncloneable encryption. We then adopt the framework for quantum authenticated key exchange, developed by Mosca et al., and extend it to introduce the notion of coercer-deniable QKE, formalized in terms of the indistinguishability of real and fake coercer views. Next, we apply results from a recent work by Arrazola and Scarani on covert quantum communication to establish a connection between covert QKE and deniability. We propose DC-QKE, a simple deniable covert QKE protocol, and prove its deniability via a reduction to the security of covert QKE. Finally, we consider how entanglement distillation can be used to enable information-theoretically deniable protocols for QKE and tasks beyond key exchange. [less ▲]

Cette contribution a pour objet d'analyser l'importance des frontières nationales pour les identités spatiales dans des régions transfrontalières. À cet effet, elle élaborera un modèle d'analyse pluridimensionnel permettant d'étudier les identités et, à l'exemple de la Grande Région SaarLorLux, posera la question de savoir comment les habitants se représentent l'espace et organisent leurs pratiques de vie quotidienne sur le plan spatial. Par ailleurs, l'analyse révèlera des projections spatiales dans le discours politique et montrera dans quelle mesure celles-ci constituent une base de processus identitaires. La contribution démontre que, malgré des imbrications transfrontalières, les frontières nationales jouent un rôle important dans les processus de projection et d'appropriation identitaires des habitants de la Grande Région SaarLorLux, mais pas nécessairement en tant que catégories rigides.

The finite-time attitude synchronization problem is considered in this paper, where the rotation of each rigid body is expressed using the axis-angle representation. Two discontinuous and distributed controllers using the vectorized signum function are proposed, which guarantee almost global and local convergence, respectively. Filippov solutions and non-smooth analysis techniques are adopted to handle the discontinuities. Sufficient conditions are provided to guarantee finite-time convergence and boundedness of the solutions. Simulation examples are provided to verify the performances of the control protocols designed in this paper. [less ▲]

In order to achieve our objective, we will first provide an overview of the development of cooperation research, its characterizing orientations and establish a link to the topic of this contribution (chapter 2). The following presentation of practice theories introduces praxeological thinking and provides a condensed outline of the state of the art of this cultural sociological theory (chapter 3). Building on this, we will develop our idea of a cross-border practice formation that breaks with the premises of traditional cooperation research, and we provide an alternative perspectivation by outlining four challenges of CBC (chapter 4). In consideration of some research-practical particularities which are linked to the suggested analytical perspective, we eventually offer (chapter 5) an outlook on the development of an alternative research approach which is compatible within a multidisciplinary context.

With the advent of Industry 4.0, a growing number of sensors within modern production lines generate high volumes of data. This data can be used to optimize the manufacturing industry in terms of complex network topology metrics commonly used in the analysis of social and communication networks. In this work, several such metrics are presented along with their appropriate interpretation in the field of manufacturing. Furthermore, the assumptions under which such metrics are defined are assessed in order to determine their suitability. Finally, their potential application to identify performance limiting resources, allocate maintenance resources and guarantee quality assurance are discussed. [less ▲]

Macroprudential policies, such as caps on loan-to-value (LTV) ratios, have become part of the policy paradigm in emerging markets and advanced countries alike. Given that housing is the most important asset in household portfolios, relaxing or tightening access to mortgages may affect the distribution of household wealth in the country. In a stylised model we show that the final level of wealth inequality depends on the size of the LTV ratio, housing prices, credit cost and the strength of a bequest motive, and therefore it is not possible to predict an unequivocal effect of LTV ratios on wealth inequality. These trade-offs are illustrated with estimations of `Gini Recentered Influence Function' regressions on household survey data from 12 Euro-zone countries that participated in the first wave of the Household Finance and Consumption Survey. The results show that, among the households with active mortgages, high LTV ratios at the time of acquisition are related to high contributions to wealth inequality today, while house price increases are negatively related to inequality contributions. A proxy for the strength of bequest motives tends to be negatively related with wealth inequality, but credit cost does not show a significant link to the distribution of wealth. [less ▲]
