description: The main objectives of this Master’s thesis may be summarized as follows:
a. The presentation of Big Data’s impact on modern applications, with particular emphasis on cybersecurity analytics. The review of the challenging aspects as an aftermath of the world’s transformation towards a data-driven culture and the identification of the arisen opportunities in the field of network security.
b. The study of machine learning utilisation in cybersecurity for the extraction of hidden knowledge in accumulated network data and the comparison between cognitive anomaly detection systems and traditional signature-based systems. The categorisation of machine-learning methods to supervised and unsupervised and the presentation of the mathematical background regarding the most common algorithms of each family, along with several cybersecurity implementations.
c. The architectural design, development and implementation of a state-of-the-art data analytics engine, in the framework of the SHIELD EU-funded cybersecurity project. The presentation of all the relevant components, placing more focus on the description of the data acquisition and data analytics modules which constitute the core of the platform.
d. The deployment, configuration, usage and testing of the Apache Spot platform as an integrated analytics ecosystem for the accomplishment of anomaly detection, using public and captured network traffic datasets. The drawing of conclusions that identify the strong and weak points of the engine and can be generalised for the majority of cognitive analytics systems.

description: The Google Shopping judgment raises the question of the possibility of attributing some of the characteristics of essential facilities to specific digital infrastructures and services. Such characteristics could lead to imposing access and neutrality obligations on digital ‘gatekeepers’ for the benefit of business partners, which may compete with some of their activities. This contribution examines the legitimacy and effectiveness of such injunctions. The aim is to examine successively the necessary scope of such obligations by questioning the place of the criterion of the indispensability of access, to consider the limits of such kind of asymmetrical regulation of competition, and to consider the possibility of addressing them through structural remedies.

description: Η παρούσα μεταπτυχιακή διατριβή έχει ως στόχο τη μελέτη του προβλήματος της
της κατανομής πόρων σε κάποιες δραστηριότητες. Η μελέτη προβλημάτων εύρεσης της βέλτιστης κατανομής πόρων είναι σημαντική καθώς πολλές φορές υπάρχει περιορισμός στη διαθεσιμότητα των πόρων ενώ παράλληλα κάποιοι επιπρόσθετοι περιορισμοί καθιστούν το πρόβλημα αρκετά πολύπλοκο. Στη διεθνή βιβλιογραφία τέτοιου είδους προβλήματα καλούνται προβλήματα κατανομής πόρων (resource allocation problems).
Στο πρώτο κεφάλαιο γίνεται μια εισαγωγή στον δυναμικό προγραμματισμό, δηλαδή πως ξεκίνησε και επινοήθηκε σαν μέθοδος, σε τι είδους προβλήματα μπορεί να δώσει λύση, ποιοι αλγόριθμοι χρησιμοποιούνται, αλλά και σε ποιους τομείς και σε ποιες καταστάσεις μπορεί να δώσει λύσεις.

description: Mean-field methods such as Hartree-Fock (HF) or Hartree-Fock-Bogoliubov (HFB) constitute the building blocks upon which more elaborate many-body theories are based on. The HF and HFB wavefunctions are built out of independent quasi-particles resulting from a unitary linear canonical transformation of the elementary fermion operators. Here, we discuss the possibility of allowing the HF transformation to become non-unitary. The properties of such HF vacua are discussed, as well as the evaluation of matrix elements among such states. We use a simple ansatz to demonstrate that a non-unitary transformation brings additional flexibility that can be exploited in variational approximations to many-fermion wavefunctions. The action of projection operators on non-unitary based HF states is also discussed and applied to the one-dimensional Hubbard model with periodic boundary conditions.

description: It is shown that the h-vectors of Stanley-Reisner rings of three classes of matroids are pure O-sequences. The classes are (a) matroids that are truncations of other matroids, or more generally of Cohen-Macaulay complexes, (b) matroids whose dual is (rank + 2)-partite, and (c) matroids of Cohen-Macaulay type at most five. Consequences for the computational search for a counterexample to a conjecture of Stanley are discussed.

Weighed scalar averaging in LTB dust models, part II: a formalism of exact perturbations
Creators: name: Sussman, Roberto A.
Publisher: name: arXiv
Year: 2013
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We examine the exact perturbations that arise from the q-average formalism that was applied in the preceding article (part I) to Lemaitre-Tolman-Bondi (LTB) models. By introducing an initial value parametrization, we show that all LTB scalars that take a FLRW "look alike" form (frequently used in the literature dealing with LTB models) follow as q-averages of covariant scalars that are common to FLRW models. These q--scalars determine for every averaging domain a unique FLRW background state through Darmois matching conditions at the domain boundary, though the definition of this background does not require an actual matching with a FLRW region (Swiss cheese type models). Local perturbations describe the deviation from the FLRW background state through the local gradients of covariant scalars at the boundary of every comoving domain, while non-local perturbations do so in terms of the intuitive notion of a "contrast" of local scalars with respect to FLRW reference values that emerge from q-averages assigned to the whole domain or the whole time slice in the asymptotic limit. We derive fluid flow evolution equations that completely determine the dynamics of the models in terms of the q-scalars and both types of perturbations. A rigorous formalism of exact spherical non-linear perturbations is defined over the FLRW background state associated to the q-scalars, recovering the standard results of linear perturbation theory in the appropriate limit. We examine the notion of the amplitude and illustrate the differences between local vs non-local perturbations by qualitative diagrams and through an example of a cosmic density void that follows from the numeric solution of the evolution equations.

description: Through digital transformation and new technologies such as virtual reality (VR), employees can benefit from enormous advantages within the corporate context. In industrial computer-aided design (CAD), there are complex workflows that have a great influence on the maintenance processes. However, designers may not be fully aware of potential benefits of these influences. To sharpen this awareness, for such scenarios the demonstration of CAD objects in VR can be a solution. Virtual testing of a design is inexpensive and can be realized quickly. In addition, maintenance can already be trained virtual in detail on the VR image of the machines. This topic is taken up representatively and implemented in an information system (IS) based on VR and a design science research approach. The needs of the employees are strongly considered in this study and the developed software can be applied to a broad class of related problems. Finally, the demonstrator and the underlying processes will be evaluated to gain insights and knowledge about the design of a VR system.
Spin-flip phonon-mediated charge relaxation in double quantum dots

description: We theoretically study the $(1,1)$ triplet to $(0,2)$ singlet relaxation rate in a lateral gate-defined double quantum dot tuned to the regime of Pauli spin blockade. We present a detailed derivation of the effective phonon density of states for this specific charge transition, keeping track of the contribution from piezoelectric as well as deformation potential electron-phonon coupling. We further investigate two different spin-mixing mechanisms which can couple the triplet and singlet states: a magnetic field gradient over the double dot (relevant at low external magnetic field) and spin-orbit interaction (relevant at high field), and we also indicate how the two processes could interfere at intermediate magnetic field. Finally, we show how to combine all results and evaluate the relaxation rate for realistic system parameters.

description: Designing synthetic microenvironments for cellular investigations is a very active area of research at the crossroads of cell biology and materials science. The present work describes the design and functionalization of a three-dimensional (3D) culture support dedicated to the study of neurite outgrowth from neural cells. It is based on a dense self-assembled collagen matrix stabilized by 100-nm-wide interconnected native fibrils without chemical crosslinking. The matrices were made suitable for cell manipulation and direct observation in confocal microscopy by anchoring them to traditional glass supports with a calibrated thickness of similar to 50 mu m. The matrix composition can be readily adapted to specific neural cell types, notably by incorporating appropriate neurotrophic growth factors. Both PC-12 and SH-SY5Y lines respond to growth factors (nerve growth factor and brain-derived neurotrophic factor, respectively) impregnated and slowly released from the support. Significant neurite outgrowth is reported for a large proportion of cells, up to 66% for PC12 and 49% for SH-SY5Y. It is also shown that both growth factors can be chemically conjugated (EDC/NHS) throughout the matrix and yield similar proportions of cells with longer neurites (61% and 52%, respectively). Finally, neurite outgrowth was observed over several tens of microns within the 3D matrix, with both diffusing and immobilized growth factors. (C) 2012 Acta Materialia Inc. Published by Elsevier Ltd.

description: We present a comparative study of DNA nucleobases [guanine (G), adenine (A), thymine (T), and cytosine (C)] adsorbed on hexagonal boron nitride (\textit{h}-BN) sheet and graphene, using local, semilocal, and van der Waals (vdW) energy-corrected density-functional theory (DFT) calculations. Intriguingly, despite the very different electronic properties of BN sheet and graphene, we find rather similar binding energies for the various nucleobase molecules when adsorbed on the two types of sheets. The calculated binding energies of the four nucleobases using the local, semilocal, and DFT+vdW schemes are in the range of 0.54 ${\sim}$ 0.75 eV, 0.06 ${\sim}$ 0.15 eV, and 0.93 ${\sim}$ 1.18 eV, respectively. In particular, the DFT+vdW scheme predicts not only a binding energy predominantly determined by vdW interactions between the base molecules and their substrates decreasing in the order of G$>$A$>$T$>$C, but also a very weak hybridization between the molecular levels of the nucleobases and the $π$-states of the BN sheet or graphene. This physisorption of G, A, T, and C on the BN sheet (graphene) induces a small interfacial dipole, giving rise to an energy shift in the work function by 0.11 (0.22), 0.09 (0.15), $-$0.05 (0.01), and 0.06 (0.13) eV, respectively.

Shifting from Sanctions to Preventive Regulation in Digital Framework: A Critical Perspective

Year: 2022

description: The historical period we are living through is characterised by the vivacity and opposing thrusts: on the one hand, in fact, it emerges clearly that the intention of the European Union regulation is inter alia to modernise the traditional system, making it more sustainable, resilient, and efficient. On the other hand, it is evident that the current war events bring attention to more concrete and current needs. In this complex framework, it is useful to proceed step by step and to pay attention to the different segments that are thus characterising the path of European legislation. Among others, it is interesting to focus on the theme of digital platforms, highlighting positive elements and possible criticalities. Digital platforms and the digitalisation of commerce, and thus, more generally, of our habits, are, in fact, profiles characterised by a multiplicity of issues that need an accurate examination. In addition to the existing relationship between technology and sustainability (still to be explored), we consider it useful to focus here on the issues of controls and responsibilities, to verify their efficiency and system compatibility. It is increasingly necessary to understand whether the usual "sanctioning" and ex-post "control" tools are adequate or far from a regulation that, instead, proves to be more efficient if proactive and intended not to allow unsuitable players to enter the market. The question addressed in this paper is whether the new rules set out in the Digital Markets Act could be the most adequate and efficient way to ensure access to the digital market by other (smaller) players. To answer this question, we will first give a brief overview of the current legal framework based on ex- post remedies. Then, we will analyse the main innovative provisions as well as the main criticisms.

Reasonable AI and Other Creatures. What Role for AI Standards in Liability Litigation?
Creators: name: Frattone, Cristina
Publisher: name: Journal of Law, Market & Innovation
Year: 2022

description: Standards play a vital role in supporting policies and legislation of the European Union. The regulation of artificial intelligence (AI) makes no exception as made clear by the AI Act proposal. Particularly, Articles 40 and 41 defer to harmonised standards and common specifications the concrete definition of safety and trustworthiness requirements, including risk management, data quality, transparency, human oversight, accuracy, robustness, and cybersecurity. Besides, other types of standards and professional norms are also relevant to the governance of AI. These include European non-harmonised standards, international and national standards, professional codes and guidelines, and uncodified best practices. This contribution casts light on the relationship between standards and private law in the context of liability litigation for damage caused by AI systems. Despite literature’s commitment to the issue of liability for AI, the role of standardisation in this regard has been largely overlooked hitherto. Furthermore, while much research has been undertaken on the regulation of AI, comparatively little has dealt with its standardisation. This paper aims to fill this gap. Building on previous scholarship, the contribution demonstrates that standards and professional norms are substantially normative in spite of their private and voluntary nature. In fact, they shape private relationships due to normative and economic reasons. Indeed, these private norms enter the courtrooms by explicit or implicit incorporation into contracts as well as by informing general clauses such as reasonableness and duty of care. Therefore, they represent the yardstick against which professionals’ performance and conduct are evaluated. Hence, a link between standards, safety, and liability can be established. Against this backdrop, the role of AI standards in private law is assessed. To set the scene, the article provides a bird’s-eye view of AI standardisation. The European AI standardisation initiative is analysed along with other institutional and non-institutional instruments. Finally, it is argued that AI standards contribute to defining the duty of care expected from developers and professional operators of AI systems. Hence, they might represent a valuable instrument for tackling the challenges posed by AI technology to extracontractual and contractual liability.

Subspace System Identification via Weighted Nuclear Norm Optimization

description: We present a subspace system identification method based on weighted nuclear norm approximation. The weight matrices used in the nuclear norm minimization are the same weights as used in standard subspace identification methods. We show that the inclusion of the weights improves the performance in terms of fit on validation data. As a second benefit, the weights reduce the size of the optimization problems that need to be solved. Experimental results from randomly generated examples as well as from the Daisy benchmark collection are reported. The key to an efficient implementation is the use of the alternating direction method of multipliers to solve the optimization problem.

description: We derive constraints on corrections to Newtonian gravity of the Yukawa type and light elementary particles from two recently performed measurements of the gradient of the Casimir force. In the first measurement the configuration of two Au surfaces has been used, whereas in the second a nonmagnetic metal Au interacted with a magnetic metal Ni. In these configurations one arrives at different, respectively, similar theoretical predictions for the Casimir force when the competing theoretical approaches are employed. Nevertheless, we demonstrate that the constraints following from both experiments are in mutual agreement and in line with constraints obtained from earlier measurements. This confirms the reliability of constraints on non-Newtonian gravity obtained from measurements of the Casimir force.

Public agents in social media regulation: The Brazilian case in a comparative perspective
Creators: name: Calil, Ana Luíza
Publisher: name: Journal of Law, Market & Innovation
Year: 2022

description: The use of social media by public agents, including politicians, is an ordinary practice throughout countries, part of the daily life of the public administration and States are currently dealing with the challenge of social media regulation. This article aims to show how social media has become a government toll throughout the years and how public agents and institutions are using this mechanism as part of the administrative routine. One of the key points is that the use of social media by governments is part of the movement to transform transparency and publicity, both from an internal point of view and for the public arena’s engagement in social participation. Based on this, the article presents the results of a research conducted to identify if social media regulation is dealing with this scenario. In Brazil, the issue of social media use in the public sector is relevant because the country has approximately 9 million public agents, and around 242 million smartphone users. Brazilian politicians have personal accounts with loads of followers. A general social media regulation in the country is being drafted – while Courts deals with content control and blocking cases. This article analyses how rules and regulations are assessing the matter, specifically if its text includes provisions for public agents or public institutions. The main goal is to identify whether there is a differentiation by the rules on the author of the content or content sharing. It investigates if there are differences on how regulations handle public and private persons. The comparative research was conducted in 8 countries and in the European Union sphere and has identified two models regarding social media regulation design. The results were compared to the Brazilian case, which presented some particularities in a comparative perspective. The research adopted the concept of regulation in an extended way. In the conclusion, a roadmap for regulators in Brazil is proposed, with three elements to be considered when drafting a social media regulation. The roadmap intends to provide guidance for regulators when dealing with the challenge of regulating social media, considering the importance of properly identifying its subject.

Competition, privacy, and justifications: Invoking privacy to justify abusive conduct under Article 102 TFEU
Creators: name: Unekbas, Selcukhan
Publisher: name: Journal of Law, Market & Innovation
Year: 2022

description: This article aims to delineate the extent to which potentially anticompetitive behaviour that simultaneously improve user privacy are cognizable as efficiencies or objective justifications within the context of unilateral conduct cases in European competition law. After mapping the existing literature, it moves on to discuss whether the decisional guidance of the European Commission, as well as the case-law of the Union Courts, allow the invocation of privacy as proper grounds to mount a defense against abusive prac- tices. In order to concretise the theoretical discussions, the article focuses on two recent and highly relevant developments: Apple’s App-Tracking Transparency initiative, and Google’s unveiling of the Privacy Sandbox. It finds that the state of the law pertaining to the second stage of an abuse case is underdeveloped and needs clarification. Nevertheless, considering the recent developments surrounding European competition law in general, and the digital transformation in particular, both efficiencies and objective justifications are likely to find room for application in the digital economy. On the one hand, efficiencies must be evaluated within the context of substantive symmetry, legal coherence, and economic considerations in a manner that caters to consumer choice. On the other hand, one must approach objective justifications with nuance, lest they give rise to unintended consequences resulting from recent judicial and legislative developments. Overall, it is apparent that the case-law provides valuable insights as to the im- plementation of efficiency arguments and objective justifications in a privacy context. However, the concepts are nonetheless in need of further analysis, in the absence of which their successful invocation re- mains rather unlikely. In that regard, the article concludes by highlighting points of potential contention in the future.

description: We investigate the non-Markovian dynamics of quantum correlation between two initially entangled nitrogen-vacancy centers (NVC) embedded in photonic crystal cavities (PCC). We find that a finite quantum correlation is preserved even asymptotically when the transition frequency of the NVC is within the band gap of the PCC, which is quantitatively different from the result of approaching zero under the Born-Markovian approximation. In addition, once the transition frequency of NVC is far beyond the band gap of the PCC, the quantum correlation initially prepared in NVC will be fully transferred to the reservoirs in the long-time limit. Our result reveals that the interplay between the non-Markovian effect of the structured reservoirs and the existence of emitter-field bound state plays an essential role in such quantum correlation preservation. This feature may open new perspectives for devising active decoherence-immune solid-state optical devices.

description: Quantum computation is a novel way of information processing which allows, for certain classes of problems, exponential speedups over classical computation. Various models of quantum computation exist, such as the adiabatic, circuit and measurement-based models. They have been proven equivalent in their computational power, but operate very differently. As such, they may be suitable for realization in different physical systems, and also offer different perspectives on open questions such as the precise origin of the quantum speedup. Here, we give an introduction to the one-way quantum computer, a scheme of measurement-based quantum computation. In this model, the computation is driven by local measurements on a carefully chosen, highly entangled state. We discuss various aspects of this computational scheme, such as the role of entanglement and quantum correlations. We also give examples for ground states of simple Hamiltonians which enable universal quantum computation by local measurements.

Non-Arrhenius ionic conductivities in glasses due to a distribution of activation energies

description: Previously observed non-Arrhenius behavior in fast ion conducting glasses [\textit{Phys.\ Rev.\ Lett.}\ \textbf{76}, 70 (1996)] occurs at temperatures near the glass transition temperature, $T_{g}$, and is attributed to changes in the ion mobility due to ion trapping mechanisms that diminish the conductivity and result in a decreasing conductivity with increasing temperature. It is intuitive that disorder in glass will also result in a distribution of the activation energies (DAE) for ion conduction, which should increase the conductivity with increasing temperature, yet this has not been identified in the literature. In this paper, a series of high precision ionic conductivity measurements are reported for $0.5{Na}_{2}{S}+0.5[x{GeS}_{2}+(1-x){PS}_{5/2}]$ glasses with compositions ranging from $0 \leq x \leq 1$. The impact of the cation site disorder on the activation energy is identified and explained using a DAE model. The absence of the non-Arrhenius behavior in other glasses is explained and it is predicted which glasses are expected to accentuate the DAE effect on the ionic conductivity.

The Uber case and gig-individuals against the backdrop of the gig-economy: Dilemmas between labour law and techno-law

description: The “Uber workers” and, more in general, individuals deployed in the platforms, overall considered the “gig economy”, have already been the subject matter of multifarious dicta in Italy. However, not only are these court decisions contradictory with each other, but also they are quite nebulous in their underpinning reasoning. Furthermore, there are a few inconsistencies with entrenched principles of the Italian legal system, particularly in the area of labour law. By contract, across the “Channel”, the Uber workers have been “dissected”, from a legal perspective, in a very recent decision of the UK Supreme Court. On such a background, it is becoming vital to ascertain the legal characterisation of “gig individuals”, also in the light of a prospective EU legal framework where this new category could be legislated. Bearing this in mind, seemingly the imminent EU regulation will engender a challenging, yet stimulating, comparative analysis with the common law (and its traditional “tests” of the contract of employment), where it still arduous to envisage any legislation in this micro-area of labour law.

description: The effect of surface stress on the stiffness of cantilever beams remains an outstanding problem in the physical sciences. While numerous experimental studies report significant stiffness change due to surface stress, theoretical predictions are unable to rigorously and quantitatively reconcile these observations. In this Letter, we present the first controlled measurements of stress-induced change in cantilever stiffness with commensurate theoretical quantification. Simultaneous measurements are also performed on equivalent clamped-clamped beams. All experimental results are quantitatively and accurately predicted using elasticity theory. We also present conclusive experimental evidence for invalidity of the longstanding and unphysical axial force model, which has been widely applied to interpret measurements using cantilever beams. Our findings will be of value in the development of micro- and nanoscale resonant mechanical sensors.

Data governance: a tale of three subjects

description: Systematic data exploitation through digital means lies at the very heart of the current platform economy. The regulatory boundaries posed by legislation to what firms and individuals can do with this intangible asset fall under the broad concept of data governance. Against this background, the article argues that the three major regulatory policy fields critical in shaping a country’s data governance framework are data control, national security and competition law. These legislative strands have a profound impact on the platform economy and overlap with each other in a significant manner. In exploring the complex trade-offs, this paper reaches two broad conclusions. First, multiple and diverse regulatory domains intersect the digital space, with overlapping and sometimes unpredictable consequences. Second, given the transnational nature of digital activity, international coordination and dialogue are of the utmost importance.

description: To interpret the mean depth of cosmic ray air shower maximum and its dispersion, we parametrize those two observables as functions of the first two moments of the $\ln A$ distribution. We examine the goodness of this simple method through simulations of test mass distributions. The application of the parameterization to Pierre Auger Observatory data allows one to study the energy dependence of the mean $\ln A$ and of its variance under the assumption of selected hadronic interaction models. We discuss possible implications of these dependences in term of interaction models and astrophysical cosmic ray sources.
