    Description: We provide an overview of legal and technical concepts of privacy protection. Data protection guarantees exist in European Union at a primary law level since 2009, when the Lisbon Treaty has become effective. The new regulation called general data protection regulation adopted on April 27, 2016 will enter into effect on May 25, 2018. Regarding data protection, the US follows a very different approach. The cornerstone of the technical framework of data protection is the concept of differential privacy for which the privacy's provable guarantees hold even against worst-case scenarios when the access to arbitrary auxiliary information is provided. Research directions for integrating legal and technical concepts of privacy are discussed. Although both fields, legal and technical, approach privacy from different perspectives, we expect that these approaches will converge to a common framework. The privacy-preserving framework, therefore, should be a balance between: 1) ambiguous legal concepts and precise mathematical notions of privacy; 2) the desired privacy level; 3) the information loss, which is measured by data utility metrics; and 4) the complexity and the practical feasibility of the proposed technique. Key notions of fairness are incompatible with each other, and hence any privacy-preserving framework should also include the trade-offs between conditions imposed in the definitions of fairness. The complex assembly of legal and technical components implementing various privacy requirements in the privacy-preserving framework, should be realized within the privacy-by-design concept.

    Description: We review models for analyzing multivariate data of mixed (heterogeneous) domains such as binary, categorical, ordinal, counts, continuous, and/or skewed continuous, and methods for modeling various graphs including multiplex, multilevel, and multilayer networks. Data are modeled with Markov random fields which encode Markov property between nodes: two nodes are not connected with an edge if and only if random variables associated with these nodes are conditionally independent, given the other variables. Inferring dependence structure through graphical models (both directed and undirected) is essential for discovering multivariate interaction among high-dimensional data, which could potentially be associated with several diseases. Networks are modeled with exponential random graph models which encode Markov property between edges: two edges are conditionally dependent, given the rest of the network, if they have a common vertex. Studying and understanding multilayer and/or multilevel representations of various phenomena, including social and natural phenomena, could lead to predictive models of these phenomena. Modeling data of heterogeneous domains and multilevel and/or multilayer networks pose challenges which are reviewed. Addressing these challenges within a unified framework stresses open problems and points out new directions for research.

    Description: A simple topology-manipulative algorithm for control of virus spreading trough complex networks is suggested. The algorithm is studied and applied on an SIS model type of an infection, and the system is described with a set of nonlinear difference probabilistic equations, that represent the dynamics of infection probabilities of nodes and existence probabilities of links in the graph. The validity of the control mechanism is first proven theoretically. Then, simulations are performed and results from both the realistic (status dependent) and probabilistic (analyzed) systems are compared, proving numerically as well, that the suggested algorithm is valid tool for infection eradication from complex networks. Several strategies of control implementation were tested and efficiency of each evaluated on the probabilistic system.

    Description: This paper presents a compression method that exploits pseudo-chaotic systems, to be applied to True Random Bit Generators (TRBGs). The theoretical explanation of the proposed compression scheme required the projection of some results achieved within the Ergodic Theory for chaotic systems on the world of digital pseudo-chaos. To this aim, a weaker and more general interpretation of the Shadowing Theory has been proposed, focusing on probability measures, rather than on single chaotic trajectories. The design of the compression scheme has been theoretically discussed in order to assure the final entropy of the compressed TRBG to be arbitrarily close to the maximum limit of 1 bit/time-step. The proposed solution requires extremely low-complex hardware circuits for being implemented, assures a constant throughput and is based on theoretical results of general validity.

    Description: A method is described for the construction of parameters' subspaces where Markov partitions can be found. The method is illustrated on the three-region piecewise linear 1-D (3PL1D) map, which is a popular approach for the chaos-based random number generator (RNG). For Markov partitions, the 3PL1D chaotic maps behave as Markov sources, and analytical calculation of its information entropy is possible, as demonstrated in this brief. From the knowledge of the stochastic transition matrix of the Markov source, one can exactly measure the appropriateness of the RNG in a given area. For classical RNGs, one typically relies on statistical tests as a quality indicator. Mathematical calculation of the quality of an RNG based on the 3PL1D chaotic maps makes the statistical tests useful only in the postimplementation phase as a verification of the hardware implementation.

    Description: Efficient control of power systems is becoming increasingly difficult as they gain in complexity and size. By considering a power grid and a communication infrastructure as a multiplex network, we propose an automatic control strategy that regulates the mechanical power output of the generators based on information obtained via communication links (wireless or wired). An algorithm that optimizes steady-state stability of a power grid by iteratively adding communication links is presented. The proposed control scheme is successfully applied to the IEEE New England and the IEEE RTS 96 power systems, leading to a significant increase in the steady-state stability of the systems and an improvement in their overall robustness. The resulting communication network topology differs significantly from the transmission grid topology. This shows how complex the steady-state control for power systems is, influenced by the generators' configuration, the transmission network topology, and the manner by which control is executed.

    Description: This brief proposes a dynamic intelligent load balancing and reactive power compensation switch plugin for power meters and a smart scalable system architecture applicable as an add-on to the existing power distribution networks. The load-balancing module will improve the load balance in a network and thus decrease power losses, whereas the distributed reactive power compensator will decrease the total reactive power. The novel approach is presented from its IT/networks perspective as well as from the physical layer with oscilloscope measurements and time analysis of the phase-swapping event.

    Description: We study synchronization and consensus phenomena in state-dependent graphs in which the edges are weighted according to the Hebbian learning rule or its modified version. By exploring the master stability function of the synchronous state, we show that the modified Hebbian function as coupling strength enlarges the stability region of the synchronous state. In terms of consensus, given that the state-dependent weights are always positive, we prove that consensus in a network of multi-agent systems is always reachable. Furthermore, we show that in state-dependent graphs the second smallest eigenvalue of the graph Laplacian matrix has larger values due to the state-dependency, resulting in speed up of the convergence process.

    Description: The incipience of synchrony in a diverse population of phase oscillators with non-identical interactions is an intriguing phenomenon. We study frequency synchronization of such oscillators composing networks with arbitrary topology in the context of the Kuramoto model and we show that its synchronization manifold is exponentially stable when the coupling has certain properties. Several example systems with periodic linear, cubic and sinusoidal coupling functions were examined, some including frustration and external fields. The numerical results confirmed the analytic findings and revealed some other interesting occurrences, like phase clustering in a synchronized network of strongly coupled oscillators. We also analyze the effects of the topology by considering random weighted networks.
