Seeing with ears: how we create an auditory representation of space with echoes and its relation with other senses
Creators: name: TONELLI, ALESSIA

description: Spatial perception is the capability that allows us to learn about the environment. All our senses are involved in creating a representation of the external world. When we create the representation of space we rely primarily on visual information, but it is the integration with the other senses that allows us a more global and truthful representation of it. While the influence of vision and the integration of different senses among each other in spatial perception has been widely investigated, many questions remain about the role of the acoustic system in space perception and how it can be influenced by the other senses. Give an answer to these questions on healthy people can help to better understand whether the same ?rules? can be applied to, for example, people that have lost vision in the early stages of development. Understanding how spatial perception works in blind people from birth is essential to then develop rehabilitative methodologies or technologies to help these people to provide for lack of vision, since vision is the main source of spatial information. For this reason, one of the main scientific objective of this thesis is to increase knowledge about auditory spatial perception in sighted and visually impaired people, thanks to the development of new tasks to assess spatial abilities. Moreover, I focus my attention on a recent investigative topic in humans, i.e. echolocation. Echolocation has a great potential in terms of improvement regarding space and navigation skills for people with visual disabilities. Several studies demonstrate how the use of this technique can be favorable in the absence of vision, both on the level perceptual level and also at the social level. Based in the importance of echolocation, we developed some tasks to test the ability of novice people and we undergo the participants to an echolocation training to see how long does it take to manage this technique (in simple task). Instead of using blind individuals, we decide to test the ability of novice sighted people to see whether technique is blind related or not and whether it is possible to create a representation of space using echolocation

Topology and interaction effects in one-dimensional systems
Creators: name: CALZONA, ALESSIO

description: With the discovery of the integer quantum Hall effect by von Klitzing and collaborators in 1980, the mathematical field of topology entered the world of condensed matter physics. Almost three decades later, this eventually led to the theoretical prediction and the experimental realization of many intriguing topological materials and topology-based devices. In this Ph.D. thesis, we will study the interplay between topology and another key topic in condensed matter physics, namely the study of inter-particle interactions in many-body systems. This interplay is analyzed from two different perspectives. Firstly, we studied how the presence of electron-electron interactions affects single-electron injection into a couple of counter-propagating one-dimensional edge channels. The latter appear at the edges of topologically non-trivial systems in the quantum spin Hall regime and they can also be engineered by exploiting the integer quantum Hall effect. Because of inter-channel interactions, the injected electron splits up into a couple of counter-propagating fractional excitations. Here, we carefully study and discuss their properties by means of an analytical approach based on the Luttinger liquid theory and the bosonization method. Our results are quite relevant in the context of the so-called electron quantum optics, a fast developing field which deeply exploits the topological protection of one-dimensional edge states to study the coherent propagation of electrons in solid-state devices. As an aside, we also showed that similar analytical techniques can also be used to study the time-resolved dynamics of a Luttinger liquid subject to a sudden change of the interaction strength, a protocol known as quantum quench which is gaining more and more attention, especially within the cold-atoms community. Secondly, we study how inter-particle interactions can enhance the topological properties of strictly one-dimensional fermionic systems. More precisely, the starting point is the seminal Kitaev chain, a free-fermionic lattice model which hosts exotic Majorana zero-energy modes at its ends. The latter are extremely relevant in the context of topological quantum computation because of their non-Abelian anyonic exchange statistics. Here we show that, by properly adding electron-electron interactions to the Kitaev chain, it is possible to obtain lattice models which feature zero-energy parafermionic modes, an even more intriguing generalization of Majoranas. To this end, we develop at first an exact mapping between Z4 parafermions and ordinary fermions on a lattice. We subsequently exploit this mapping to analytically obtain an exactly solvable fermionic model hosting zero-energy parafermions. We study their properties and numerically investigate their signatures and robustness even when parameters are tuned away from the exactly solvable point.

description: Intense flares that occur at late times relative to the prompt phase have been observed by the $Swift$ satellite in the X-ray afterglows of gamma-ray bursts (GRBs). Here, we present a detailed analysis on the fall back accretion process to explain the intense flare phase in the very early X-ray afterglow light curves. To reproduce the afterglow at late times, we resort to the external shock by engaging energy injections. By applying our model to GRBs 080810, 081028 and 091029, we show that their X-ray afterglow light curves can be reproduced well. We then apply our model to the ultra-long $Swift$ GRB 111209A, which is the longest burst ever observed. The very early X-ray afterglow of GRB 111209A showed many interesting features, such as a significant bump observed at around 2000 s after the $Swift$/BAT trigger. We assume two constant energy injection processes in our model. These can explain the observed plateau at X-ray wavelength in the relatively early stage ($8.0\times10^{3}$ s) and a second X-ray plateau and optical rebrightening at about $10^{5}$ s. Our analysis supports the scenario that a significant amount of material may fall back toward the central engine after the prompt phase, causing an enhanced and long lived mass accretion rate powering a Poynting-flux-dominated outflow.

description: Printed electronics (PE) promises on-demand fabrication, low non-recurring engineering costs, and sub-cent fabrication costs. It also allows for high customization that would be infeasible in silicon, and bespoke architectures prevail to improve the efficiency of emerging PE machine learning (ML) applications. Nevertheless, large feature sizes in PE prohibit the realization of complex ML models in PE, even with bespoke architectures. In this work, we present an automated, cross-layer approximation framework tailored to bespoke architectures that enable complex ML models, such as Multi-Layer Perceptrons (MLPs) and Support Vector Machines (SVMs), in PE. Our framework adopts cooperatively a hardware-driven coefficient approximation of the ML model at algorithmic level, a netlist pruning at logic level, and a voltage over-scaling at the circuit level. Extensive experimental evaluation on 12 MLPs and 12 SVMs and more than 6000 approximate and exact designs demonstrates that our model-to-circuit cross-approximation delivers power and area optimal designs that, compared to the state-of-the-art exact designs, feature on average 51% and 66% area and power reduction, respectively, for less than 5% accuracy loss. Finally, we demonstrate that our framework enables 80% of the examined classifiers to be battery-powered with almost identical accuracy with the exact designs, paving thus the way towards smart complex printed applications.

description: Starting from the assumption of Donna Haraway for which the cyborg, a hybrid entity between organic body and cybernetic mechanism, embodies the ability to interrupt the dualism that sees the natural body in opposition to the technologically reconstructed body and becomes a starting point for the development of the perspective of posthuman thought, I analyze how Japanese women respond to socio-cultural changes and technological and biomedical developments, and how many technologies have contributed and still contribute to the construction of new female subjectivities. In this perspective, I examine three contemporary authors (Wataya Risa, Taguchi Randy and Murata Sayaka) with the aim of analyzing the relationship between bodies and female identities and the different technologies in the digital age.

description: We study intersecting brane systems that realize a class of singular monopole configurations in four-dimensional Yang-Mills-Higgs theory. Singular monopoles are solutions to the Bogomolny equation on R^3 with a prescribed number of singularities corresponding to the insertion of 't Hooft defects. We use the brane construction to motivate a recent conjecture on the conditions for which the moduli space of solutions is non-empty. We also show how branes provide physical intuition for various aspects of the dimension formula derived in {arXiv:1404.5616}, including the contribution to the dimension from the defects and its invariance under Weyl reflections of the 't Hooft charges. Along the way we uncover and illustrate new dynamical phenomena for the brane systems, including a description of smooth monopole extraction and bubbling from 't Hooft defects.

description: Over the past few years, deep learning techniques have achieved tremendous success in many visual understanding tasks such as object detection, image segmentation, and caption generation. Despite this thriving in computer vision and natural language processing, deep learning has not yet shown signicant impact in robotics. Due to the gap between theory and application, there are many challenges when applying the results of deep learning to the real robotic systems. In this study, our long-term goal is to bridge the gap between computer vision and robotics by developing visual methods that can be used in real robots. In particular, this work tackles two fundamental visual problems for autonomous robotic manipulation: affordance detection and ne-grained action understanding. Theoretically, we propose dierent deep architectures to further improves the state of the art in each problem. Empirically, we show that the outcomes of our proposed methods can be applied in real robots and allow them to perform useful manipulation tasks.

description: We present a wide dataset of gamma-ray, X-ray, UVOIR, and radio observations of the Swift GRB100814A. At the end of the slow decline phase of the X-ray and optical afterglow, this burst shows a sudden and prominent rebrightening in the optical band only, followed by a fast decay in both bands. The optical rebrightening also shows chromatic evolution. Such a puzzling behaviour cannot be explained by a single component model. We discuss other possible interpretations, and we find that a model that incorporates a long-lived reverse shock and forward shock fits the temporal and spectral properties of GRB100814A the best.

title: Social mobility and international graduates in China
Creators: name: Zhai, Keyu
Publisher: name: University of Glasgow

description: By comparing the social and spatial mobility of international and home graduates, this is a unique study into Chinese international graduates’ post-study living and working experiences. It aims to address the overarching research question: What is the social mobility of international graduates in China? To answer this question, I proposed five sub-questions: 1) What are the labour market outcomes of Chinese students obtaining master’s degrees abroad compared with those of non-mobile Chinese graduates? 2) What factors affect international and home graduates’ labour market success in China? 3) What is the perceived social mobility of international graduates compared with that of home graduates in China? 4) What is the relationship between social and spatial mobility of international and home graduates in China? 5) What roles do international graduates play in social class formation and culture and lifestyle change in China? Adopting a mixed-methods approach to research and a pragmatic paradigm, this study employs survey and in-depth interviews to collect data. A multi-regression model, mapping analysis and thematic analysis are used to analyse the data. Although home graduates perform better in the labour market and upward social mobility than the international graduates, the international graduates are still favoured by China’s labour market and have more opportunities to develop their careers through their accumulated cultural and social capital. Interestingly, their labour market outcomes and social mobility are closely connected to their spatial mobility. The analyses reveal that the likelihood of studying abroad is linked to one’s place of origin and positively associated with parental socio-economic status. Moreover, the results of the mapping analysis highlight the uneven opportunities for spatial mobility when comparing international returnees with their peers. Therefore, this study recommends that policymakers should focus on social security and institutions for high-end home graduates. Increasing equality of education opportunities, especially the chances of studying abroad, can shrink the social mobility and inequality gaps.

description: L?attuale scenario energetico globale richiede una costante attenzione verso nuove risorse che possano sostituire le classiche fonti fossili. Allo stesso tempo � difficile prevedere in quale settore si potranno affermare le tecnologie del futuro, capaci di avere buoni rendimenti di conversione e ampia disponibilit� di risorsa primaria. Un settore che genera pertanto un forte interesse � quello riferito alla conversione energetica dal moto ondoso. La ricerca in questo ambito si spende da anni per identificare le soluzioni pi� promettenti capaci di essere robuste, replicabili e a basso costo. Ad oggi nessuna tecnologia si � dimostrata significativamente migliore delle altre, pertanto, numerosi enti si cimentano nella realizzazione del proprio dispositivo. Oggetto di questa tesi � quindi una dettagliata analisi del sistema di conversione dal moto ondoso sviluppato dal Thermochemical Power Group del Dipartimento DIME dell?Universit� degli Studi di Genova, il Seaspoon. Tale dispositivo ha subito negli anni numerose modifiche giustificate da svariate attivit� sperimentali e di simulazione. La tesi affronter� quindi i principali passi che hanno portato alla definizione dei primi prototipi in scala, per poi arrivare allo sviluppo del Seaspoon installato in mare aperto nel 2015. In conclusione, verr� descritto il progetto Sea Wham che ha portato alla progettazione e alla realizzazione di un?innovativa facility per la generazione di onde, il Wave Lab, e allo sviluppo dell?ultimo concept di Seaspoon.

Uncertainty-aware Confidentiality Analysis Using Architectural Variations

description: Bei der Planung von Software-Architekturen sind viele Aspekte des zu entwickelnden Systems noch unklar. Je größer die Architektur ist, desto mehr Entwurfsentscheidungen enthält sie und desto mehr Ungewissheiten bestehen über das System. Selbst wenn bereits ein Feinentwurf der Architektur existiert, kann es immernoch ungewisse Aspekte geben, wie z. B. Nutzereingaben. Softwaresysteme enthalten in der Regel Daten, auf die nur autorisierte Personen Zugriff haben sollen. Darüber hinaus müssen Unternehmen Gesetze einhalten, die die Verwendung oder Speicherung von Daten vorschreiben. Verstöße gegen die Vertraulichkeit von Daten können Unternehmen teuer zu stehen kommen. Daher ist es dringend ratsam, die Einhaltung von Vertraulichkeitsanforderungen bereits im Entwurfsprozess zu berücksichtigen, auch wenn die Architektur noch nicht vollständig definiert ist. Bisherige Ansätze zur Analyse der Vertraulichkeit liefern verfälschte Ergebnisse, wenn Ungewissheiten einbezogen werden sollen oder ignorieren Ungewissheit vollständig. Um überprüfen zu können, ob in einer Architektur Verstöße gegen Vertraulichkeits-Richtlinien auftreten, muss derzeit untersucht werden, wo die Ungewissheit auftritt und welche Auswirkungen sie auf die Elemente der Architektur hat. Außerdem kann eine große Architektur sehr komplex werden, so dass es schwieriger wird, alle Stellen zu finden, an denen Vertraulichkeitsverletzungen auftreten können. Dies stellt eine Hürde für Softwarearchitekten dar, Vertraulichkeitsverletzungen in ihrer Gesamtheit abzufangen und Vertraulichkeit nach Änderungen im Entwurf zu erhalten. In dieser Arbeit stellen wir einen Ansatz vor, der die Ergebnisse bestehender Vertraulichkeitsanalysen mit Modellierungsfähigkeiten über Ungewissheiten kombiniert. Hierfür entwickeln wir einen Algorithmus, der als Eingabe Informationen über die Ungewissheit, die Architektur und die aufgetretenen Vertraulichkeitsverletzungen erhält. Das Ergebnis ist eine Analyse, die Ungewissheiten hinsichtlich ihrer Auswirkungen auf eine Vertraulichkeitsverletzung untersucht und einem Softwarearchitekten schneller zeigt, wo und warum Vertraulichkeitsverletzungen auftreten. Der Algorithmus ist auf die Möglichkeit einer zukünftigen Erweiterung ausgelegt. Wir evaluieren unseren Ansatz, indem wir ihn auf Fallstudien anwenden und die Nutzbarkeit und Durchführbarkeit prüfen. Unter der Annahme, dass wir architektonische Ungewissheit als Variationen beschreiben können, die zu Szenarien der Architektur führen, zeigen die Ergebnisse, dass der Ansatz Ungewissheitseinflüsse herausfiltern kann, die nicht für Vertraulichkeitsverletzungen verantwortlich sind.

description: We develop semistrict higher gauge theory from first principles. In particular, we describe the differential Deligne cohomology underlying semistrict principal 2-bundles with connective structures. Principal 2-bundles are obtained in terms of weak 2-functors from the Cech groupoid to weak Lie 2-groups. As is demonstrated, some of these Lie 2-groups can be differentiated to semistrict Lie 2-algebras by a method due to Severa. We further derive the full description of connective structures on semistrict principal 2-bundles including the non-linear gauge transformations. As an application, we use a twistor construction to derive superconformal constraint equations in six dimensions for a non-Abelian N=(2,0) tensor multiplet taking values in a semistrict Lie 2-algebra.

description: In this paper we study the Haefliger invariant for long embeddings $\mathbb{R}^{4k-1}\hookrightarrow\mathbb{R}^{6k}$ in terms of the self-intersections of their projections to $\mathbb{R}^{6k-1}$, under the condition that the projection is a generic long immersion $\mathbb{R}^{4k-1}\looparrowright\mathbb{R}^{6k-1}$. We define the notion of "crossing changes" of the embeddings at the self-intersections and describe the change of the isotopy classes under crossing changes using the linking numbers of the double point sets in $\mathbb{R}^{4k-1}$. This formula is a higher-dimensional analogue to that of X.-S. Lin and Z. Wang for the order $2$ invariant for classical knots. As a consequence, we show that the Haefliger invariant is of order two in a similar sense to Birman and Lin. We also give an alternative proof for the result of M. Murai and K. Ohba concerning "unknotting numbers" of embeddings $\mathbb{R}^3\hookrightarrow\mathbb{R}^6$. Our formula enables us to define an invariant for generic long immersions $\mathbb{R}^{4k-1}\looparrowright\mathbb{R}^{6k-1}$ which are liftable to embeddings $\mathbb{R}^{4k-1}\hookrightarrow\mathbb{R}^{6k}$. This invariant corresponds to V. Arnold's plane curve invariant in Lin-Wang theory, but in general our invariant does not coincide with order $1$ invariant of T. Ekholm.

description: We report a technique for experimental characterization of an $M$-mode quantum optical process, generalizing the single-mode coherent-state quantum-process tomography method [M. Lobino et al., Science 322, 563 (2008); A. Anis and A.I. Lvovsky, New J. Phys. 14, 105021 (2012)]. By measuring effect of the process on multi-mode coherent states via balanced homodyne tomography, we obtain the process tensor in the Fock basis. This rank-$4M$ tensor, which predicts the effect of the process on an arbitrary density matrix, is iteratively reconstructed directly from the experimental data via the maximum-likelihood method. We demonstrate the capabilities of our method using the example of a beam splitter, reconstructing its process tensor within the subspace spanned by the first three Fock states. In spite of using purely classical probe states, we recover quantum properties of this optical element, in particular the Hong-Ou-Mandel effect.

Publisher: name: Universit� degli studi di Genova
Year: 2022

description: The aim of this thesis is to investigate structural determinants of economic performance from Classical Age to the dawn of the Industrial Revolution with an interdisciplinary approach. To this end, I adopted an inter-temporal comparison covering around two thousands years, putting together Economics, History, and quantitative analysis. What emerges from my studies is that every period of pre-industrial history shows different way to lead economic performance that not always reflects the Malthusian model prediction. The ability of economy to positively respond to the fixity of land and to the diminishing returns of labor made the difference between societies that was trapped in the Malthusian stagnation and which do not. However, these dynamics emerge only when a long-run approach is adopted, allowing comparison between technologies, market structures and institutions in different periods. This thesis aims to show the potential emerging from exchanges and collaboration between economists, economic historians, and ancient historians in explaining the economic development in a more comprehensive manner.

description: We examine the semicrossed products of a semigroup action by $*$-endomorphisms on a C*-algebra, or more generally of an action on an arbitrary operator algebra by completely contractive endomorphisms. The choice of allowable representations affects the corresponding universal algebra. We seek quite general conditions which will allow us to show that the C*-envelope of the semicrossed product is (a full corner of) a crossed product of an auxiliary C*-algebra by a group action. Our analysis concerns a case-by-case dilation theory on covariant pairs. In the process we determine the C*-envelope for various semicrossed products of (possibly nonselfadjoint) operator algebras by spanning cones and lattice-ordered abelian semigroups. In particular, we show that the C*-envelope of the semicrossed product of C*-dynamical systems by doubly commuting representations of $\mathbb{Z}^n_+$ (by generally non-injective endomorphisms) is the full corner of a C*-crossed product. In consequence we connect the ideal structure of C*-covers to properties of the actions. In particular, when the system is classical, we show that the C*-envelope is simple if and only if the action is injective and minimal. The dilation methods that we use may be applied to non-abelian semigroups. We identify the C*-envelope for actions of the free semigroup $\mathbb{F}_+^n$ by automorphisms in a concrete way, and for injective systems in a more abstract manner. We also deal with C*-dynamical systems over Ore semigroups when the appropriate covariance relation is considered.

description: The Newtonian dynamics of particles in brane gravity is investigated. Due to the coupling of the particles' energy-momentum tensor to the tension of the brane, the particle is semi-confined and oscillates along the extra dimension. We demonstrate that the frequency of these oscillations is proportional to the kinetic energy of the particle in the brane. We show that the classical stability of particle trajectories on the brane gives us the Bohr--Sommerfeld quantization condition. The particle's motion along the extra dimension allows us to formulate a geometrical version of the uncertainty principle. Furthermore, we exhibited that the particle's motion along the extra dimension is identical to the time-independent Schrödinger equation. The dynamics of a free particle, particles in a box, a harmonic oscillator, a bouncing particle, and tunneling are re-examined. We show that the particle's motion along the extra dimension yields a quantized energy spectrum for bound states.

description: A granular material is observed to flow under the Coulomb yield criterion as soon as this criterion is satisfied in a remote but contiguous region of space. We investigate this non-local effect using discrete element simulations, in a geometry similar, in spirit, to the experiment of Reddy et al. (Phys. Rev. Lett., 106 (2011) 108301): a micro-rheometer is introduced to determine the influence of a distant shear band on the local rheological behaviour. The numerical simulations recover the dominant features of this experiment: the local shear rate is proportional to that in the shear band and decreases (roughly) exponentially with the distance to the yield conditions. The numerical results are in quantitative agreement with the predictions of the non-local rheology proposed by (Phys. Rev. Lett., 111 (2013) 238301) and derived from a gradient expansion of the rheology $μ[I]$. The consequences of these findings for the dynamical mechanisms controlling non-locality are finally discussed.

description: This article considers the problem of sparse estimation of canonical vectors in linear discriminant analysis when $p\gg N$. Several methods have been proposed in the literature that estimate one canonical vector in the two-group case. However, $G-1$ canonical vectors can be considered if the number of groups is $G$. In the multi-group context, it is common to estimate canonical vectors in a sequential fashion. Moreover, separate prior estimation of the covariance structure is often required. We propose a novel methodology for direct estimation of canonical vectors. In contrast to existing techniques, the proposed method estimates all canonical vectors at once, performs variable selection across all the vectors and comes with theoretical guarantees on the variable selection and classification consistency. First, we highlight the fact that in the $N>p$ setting the canonical vectors can be expressed in a closed form up to an orthogonal transformation. Secondly, we propose an extension of this form to the $p\gg N$ setting and achieve feature selection by using a group penalty. The resulting optimization problem is convex and can be solved using a block-coordinate descent algorithm. The practical performance of the method is evaluated through simulation studies as well as real data applications.

Estimation and interpretation of the cross-power spectrum to quantify brain connectivity from electrophysiological data

description: Magneto- and electro- encephalography (MEEG) are two neuroimaging tools capable of non invasively recording the magnetic field outside the head and the scalp potential produced by the electric currents that flow inside the brain. Their strong point is the extremely high temporal resolution which makes them suitable for the study of functional connectivity, i.e. the quantification of the statistical dependencies among the time courses that describe brain activity. Functional connectivity is usually estimated from MEEG data with a two-step process: (i) first an estimate of the time courses associated with brain activity is computed by means of a regularisation method; (ii) then, source space functional connectivity is computed from the estimated time courses. The most widely used regularisation method to face this problem is Tikhonov regularisation, also known as Minimum Norm Estimate (MNE), which requires the setting of a regularisation parameter. Such a parameter will be used throughout the process and will influence the final connectivity estimate. In the core part of this thesis we will show that the regularisation parameter providing the best estimate of brain activity does not provide the best possible connectivity estimate. Indeed, a smaller parameter should be set for the latter intent. This result will be supported by both analytical and numerical proofs. Our results highlight that the classic two-step approach plus Tikhonov regularisation presents two intrinsic drawbacks: (i) the propagation of the errors during the process, and (ii) a connectivity estimate which is over spread in space, due to Tikhonov regularisation. In this thesis we will present a one-step approach combined with the l1 regularisation, where source space functional connectivity is directly estimated from that at sensor space, without a prior estimation of source time courses. The proposed pipeline overcomes the problems of the classic approach and outperforms it, indeed, the one-step approach reduces the propagation of the errors and the l1 regularisation promotes sparsity on the connectivity estimate. Finally, we will present transfreq, a Python package for the automated computation of the theta-to-alpha transition frequency. A correct estimation of such a quantity is of utmost importance for the reliability of connectivity studies in both healthy subjects and patients.

description: The tension between the best fit parameters derived by the Planck team and a number of other astronomical measurements suggests either systematics in the astronomical measurements, systematics in the Planck data, the need for new physics, or a combination thereof. We re-analyze the Planck data and find that the $217\,\text{GHz}\times 217\,\text{GHz}$ detector set spectrum used in the Planck analysis is responsible for some of this tension. We use a map-based foreground cleaning procedure, relying on a combination of 353 GHz and 545 GHz maps to reduce residual foregrounds in the intermediate frequency maps used for cosmological inference. For our baseline data analysis, which uses 47% of the sky and makes use of both 353 and 545 GHz data for foreground cleaning, we find the $Λ$CDM cosmological parameters $Ω_c h^2 = 0.1170 \pm 0.0025$, $n_s = 0.9686 \pm 0.0069$, $H_0 = 68.0 \pm 1.1\,\mathrm{km} \mathrm{s}^{-1}\mathrm{Mpc}^{-1}$, $Ω_b h^2 = 0.02197 \pm 0.00026$, $\ln 10^{10}A_s = 3.082 \pm 0.025$, and $τ= 0.090 \pm 0.013 $. While in broad agreement with the results reported by the Planck team, these revised parameters imply a universe with a lower matter density of $Ω_m=0.302\pm0.015$, and parameter values generally more consistent with pre-Planck CMB analyses and astronomical observations. We compare our cleaning procedure with the foreground modeling used by the Planck team and find good agreement. The difference in parameters between our analysis and that of the Planck team is mostly due to our use of cross-spectra from the publicly available survey maps instead of their use of the detector set cross-spectra which include pixels only observed in one of the surveys. We show evidence suggesting residual systematics in the detector set spectra used in the Planck likelihood code, which is substantially reduced for our spectra.

description: Recent years have witnessed impressive progress in super-resolution (SR) processing. However, its real-time inference requirement sets a challenge not only for the model design but also for the on-chip implementation. In this paper, we implement a full-stack SR acceleration framework on embedded GPU devices. The special dictionary learning algorithm used in SR models was analyzed in detail and accelerated via a novel dictionary selective strategy. Besides, the hardware programming architecture together with the model structure is analyzed to guide the optimal design of computation kernels to minimize the inference latency under the resource constraints. With these novel techniques, the communication and computation bottlenecks in the deep dictionary learning-based SR models are tackled perfectly. The experiments on the edge embedded NVIDIA NX and 2080Ti show that our method outperforms the state-of-the-art NVIDIA TensorRT significantly, and can achieve real-time performance.

description: In the last decades, computer security has been a constantly growing concern. Nowadays it is a common understanding that, although crucial, technology alone is not the ultimate solution. To effectively and promptly face new menaces, well-trained security experts and a properly designed process are necessary. Both of them can only be attained via a proper cybersecurity culture. In this thesis, we address the problems related to the correct cybersecurity mindset. In particular, we focus on two important aspects, i.e., (i) using security testing to show the lack of a correct mindset in the wild, and (ii) develop new and effective security training techniques. For security testing, we present a novel attacker model targeting security scanners. We developed RevOK, an automatic testing tool for our attacker model, and we applied it to detect several ulnerabilities in real-world scanners, including two severe vulnerabilities (CVE-2020-7354 and CVE-2020-7355) that allowed Remote Command Execution in Metasploit Pro. We also investigate a recently proposed attacker model, i.e., adversarial machine learning, and explored its application to machine learning-based Web Application Firewalls (WAF). We developed a proof-of-concept mutational fuzzer, WAF-A-MoLE, that automatically performs SQL injection attacks that bypass WAF analysis. This work shows that both attacker models have been largely neglected by security product developers. For security training, we start by considering our experience with a non-formal, hands-on training course held at the University of Genova. The main lesson learned is that having fresh and stimulating exercises is fundamental for the training process. Then, leveraging on this experience, we developed a Damn Vulnerable Application Scanner (DVAS) that provides a training environment for the RevOK attacker model. Finally, we propose a computer-aided framework that supports trainers by partially automating the design and development of new exercises in order to avoid training repetition.
