description: This thesis focuses on probabilistic interference modelling in wireless communication networks. In particular, we consider uplink cellular networks that deploy base stations (BS) equipped with a single antenna, a linear antenna array, or a planar antenna array. The thesis covers interference distribution modelling under the three BS antenna deployment scenarios. The interference is determined by the locations of the interferers, and presents various features as the BS antenna arrangement varies.
 We first study a cellular network deploying single-antenna BSs under the topic Poisson cellular networks. We resort to this mathematical tool to capture the fluctuation of the number of users in a certain area. The spatial blocking probability is studied. More importantly, it enables us to characterise the distance-dependent interference, and also the signal-to-interference related system performance metrics such as coverage probability.
 We then consider a system deploying a large linear antenna array at the BS, under the topic 2D beamforming. The beamforming antenna pattern is incorporated into the interference modelling, such that the interference is determined by the direction as well as the distance of the interferer. We develop a novel approach to characterise the direction-dependent interference by investigating a system under pure LoS / Rician fading channels with perfect uplink power control. The coverage probability and rate are also studied. Next we study a system under pure LoS channels without power control. With the aid of stochastic geometry, we present an interference model considering both the direction and the distance of the interferer.
 Next we move on to the topic 3D beamforming to investigate the interference with a large planar antenna array. The users are located in a 3D cell, hence the direction of a user is more complicated. The geometry of the cell also becomes relevant in the interference analysis. We first study a scenario where a horizontal planar array in the sky provides service to the users on the ground. A model is proposed to describe the interference determined by the user’s direction in the 3D space. Then we consider a cell where a vertical planar array communicates to users on different floors. The interference incorporating both the 3D direction and the distance is characterised, and applied to the coverage and rate analysis.
Brazilian evangélicos in diaspora in South Florida: identity, ecclesiology and mission
Creators: name: Reis, Matheus
Publisher: name: The University of Edinburgh

description: Although there has been a rise in interest in the study of migrant churches in current World Christianity Scholarship, one of the gaps in scholarship today is Lusophone Christianity in the US. This is in part due to the fact that the latest in- depth studies of Latino Christianity in the US tend to overlook Brazilian congregations in their findings. In order to help address this gap in scholarship, this thesis explores the complex practical relationship between identity, ecclesial practices and mission among members of three Brazilian evangélico churches in South Florida. Its primary goal is to investigate the significance that Christianity has for Brazilian evangélicos living in diaspora in South Florida and the ways in which evangélico churches shape their mission and practices around this reality. It analyzes the variety of means employed within evangélico communities to aid Brazilian migrants from different generations in negotiating processes of reception, survival, and integration within the Florida context. South Florida was chosen for this study because it is home to the largest community of Brazilian migrants in the US, and Florida also has the third largest concentration of Latinos in the country. This thesis is based on ethnographic fieldwork conducted primarily on three church sites located in two of Florida’s southernmost counties, namely Palm Beach and Broward. Although there is a historical element to this thesis, when it explores the history of the waves of Brazilian migration to the US (chapter 2) and the historical context of Brazilian Protestantism in Brazil (chapter 3), and of sociology of religion, when it investigates the socioeconomic context of Brazilian evangélicos, it is primarily a contemporary study of Brazilian Protestant Christianity in the US, illustrated by a number of case studies (chapters 3 through 6). This thesis found that these Brazilian evangélico churches aid their congregants in navigating life as immigrants in the US first and foremost through the leadership of pastors, who are also immigrants themselves. Given the undocumented status of most evangélico church members, pastors face the challenge of how to deal with undocumented parishioners from both a theological and a practical standpoint. Brazilian Protestant churches in South Florida form communities of support for evangélicos of different generations. These communities of support were explored through the theme of church as an extended family. The way in which the mission of these evangélico churches is both understood and practiced is the result of how a particular gathered church tradition, conservative in both theology and politics, is reinforced in both its strengths and its weaknesses by the collective experience of being a migrant minority in a kind of Promised Land that never quite fulfils its promise.
The instability of Wilton ripples

description: Wilton ripples are a type of periodic traveling wave solution of the full water wave problem incorporating the effects of surface tension. They are characterized by a resonance phenomenon that alters the order at which the resonant harmonic mode enters in a perturbation expansion. We compute such solutions using non-perturbative numerical methods and investigate their stability by examining the spectrum of the water wave problem linearized about the resonant traveling wave. Instabilities are observed that differ from any previously found in the context of the water wave problem.
Investigating the alpha-clustering on the surface of $^{120}$Sn via ($p$,$pα$) reaction and the validity of the factorization approximation

description: The $^{120}$Sn($p$,$pα$)$^{116}$Cd reaction at 392 MeV is investigated with the distorted wave impulse approximation (DWIA) framework. We show that this reaction is very peripheral mainly because of the strong absorption of $α$ by the reaction residue $^{116}$Cd, and the $α$-clustering on the nuclear surface can be probed clearly. We investigate also the validity of the so-called factorization approximation that has frequently been used so far. It is shown that the kinematics of $α$ in the nuclear interior region is significantly affected by the distortion of $^{116}$Cd, but it has no effect on the reaction observables because of the strong absorption in that region.
The place of civic education in the Greek education system: Problems, inconsistencies, contradictions and stakes

description: Purpose: In this Report we analyse the place of civic education in the Greek Education system. The integration of civic education into education since 1982 represents a major step forward in the upgrading of general education. However the curricula are mainly characterised by teacher-centred approaches, with a strong emphasis on the achievement of cognitive objectives and little emphasis on the learning process and teaching strategy. Design/methodology/approach: This report is based on an analysis of the place of social studies in the Greek education system. We analysed the aims of the curricula, the role of teachers, the didactic approaches, the educational practices and the assessment. Findings: From our analysis we have detected a gap between the public rhetoric about the role of social sciences and their implementation in the Greek education. Although it seems that the general principles of curricula are permeated by a more democratic and flexible note which encourages critical thinking and participation, they are not implemented in practice and by and large are annulled due to the great emphasis the Greek education system places on knowledge acquisition and exams. The elimination of Social studies in some classes points to a school which is cut off from the current socio-economic reality, thus condemning students to a passive attitude towards social and educational affairs. Research limitations/implications This article reports on the research conducted on civic education since the 1990’s and onwards. The study of all these researches leads us to the conclusion that neither the curricula nor the textbooks of social studies courses have been extensively analysed, and this could be a future field of research. Another area of research is the role of school charters, the didactic approaches and the assessment in this course in the Greek education context. Practical implications Upheavals in the history of the Greek governmental system and democracy left their indelible mark on citizens’ education; changes in the title of the course, the time allotted to its teaching and the content of school knowledge evidence its dependence on the respective socio-political and ideological regime as well as its indoctrinational character. The turning points in civic education which can be pinpointed between 1982 and 2003 were linked with the educational policy of socialist governments and the gradual paradigm shift in social studies.

description: Purpose: The essay wonders about forms and ways of participation in the public sphere of adolescents. The investigated practices include individual and collective participation in different contexts (in the community, at school, among peers), in physical or web presence. Design/ methodology/ approach: A web survey was carried out involving about 1,300 adolescents (14-17 years old) in five Italian urban contexts, different in size and geographical location. Findings: Cognitive and actionable findings regarding adolescents’ participation. Research limitations/ implications: Self-completed questionnaire, involvement of adolescents not attending project partner schools, not statistically representative samples but good enough for our particular purpose. Practical implications: Empirical evidence a) provide deep knowledge of adolescents, b) identify constructive approaches to promote participatory skills and full and conscious involvement in community life, c) are useful for local project partners and other operators involved in adolescents’ education promoting community-based interventions for well-being and preventing the disadvantaged situation in young people, and d) will represent the basis of local research training workshops.

description: We aim to describe a droplet bouncing on a vibrating bath using a simple and highly versatile model inspired from quantum mechanics. Close to the Faraday instability, a long-lived surface wave is created at each bounce, which serves as a pilot wave for the droplet. This leads to so called walking droplets or walkers. Since the seminal experiment by {\it Couder et al} [Phys. Rev. Lett. {\bf 97}, 154101 (2006)] there have been many attempts to accurately reproduce the experimental results. We propose to describe the trajectories of a walker using a Green function approach. The Green function is related to the Helmholtz equation with Neumann boundary conditions on the obstacle(s) and outgoing boundary conditions at infinity. For a single-slit geometry our model is exactly solvable and reproduces some general features observed experimentally. It stands for a promising candidate to account for the presence of arbitrary boundaries in the walker's dynamics.

description: How do professionals constitute their homes under conditions of extensive mobility? The study is based on interviews with professionals working for an international organization who are chronically mobile. Despite their high mobility, they describe little difficulty constructing homes. Home can best be understood here not as a fixed location, but as a set of relationships, to both humans and non-humans. There are elements of spatial proximity, but also of distance, and homes may be defined by both objects present and excluded. They may be a focal point, but at the same time part of a heterogeneous network that spans localities as well as binds past and present. Home is therefore territorially defined, but only as an extended network rather than as a bounded location.

Between the lifeworld and academia: Defining political issues in social science education
Creators: name: Mathé, Nora Elise Hesby
name: Sandahl, Johan
Publisher: name: JSSE - Journal of Social Science Education
Year: 2023

description: Highlights: • We identified four aspects for defining political issues. • Political issues are collective. • Political issues are conflictual in nature. • Political issues are contemporary issues. • Issues are political due to contextual factors. Purpose: The purpose of this study is to discuss mutual understandings of political issues among students and academics. The aim is to suggest a framework that teachers can use to address politics from both the discipline’s and the students’ perspectives. Design/methodology/approach: This study is based on semi-structured interviews with twelve students in six upper secondary schools and eight social science academics in Norway and Sweden. Findings: We identified four guiding aspects for defining political issues in social science education to connect disciplinary thinking with students’ views of the political. These aspects are: 1) collective, 2) contemporary, 3) conflictual, and 4) contextual. Limitations: This study relied on interviews with a selection of students and academics and what they chose to express. The results may not be applicable to other samples. Implications: The framework presented can be used in social science education to understand and discuss the nature of political issues.

As an application we show that if the field $K$ is algebraically closed and of characteristic different from two, and $n\leq 5$ then $\operatorname{gr}_\mathfrak{m} K[H]$ is Koszul if and only if (possibly after a change of coordinates) its defining ideal has a quadratic Gröbner basis.

description: We investigate the transmission properties of a spin transistor coupled to two quantum point contacts acting as spin injector and detector. In the Fabry-Perot regime, transport is mediated by quasibound states formed between tunnel barriers. Interestingly, the spin-orbit interaction of the Rashba type can be tuned in such a way that nonuniform Rashba fields can point along distinct directions in different points of the sample. We discuss both spin-conserving and spin-flipping transitions as the spin-orbit angle of orientation increases from parallel to antiparallel configurations. Spin precession oscillations are clearly seen as a function of the length of the central channel. Remarkably, we find that these oscillations combine with the Fabry-Perot motion giving rise to quasiperiodic transmissions in the purely one-dimensional case. Furthermore, we consider the more realistic case of a finite width in the transverse direction and find that the coherent oscillations become deteriorated for moderate values of the spin-orbit strength. Our results then determine the precise role of the Rashba intersubband coupling potential in the Fabry-Perot-Datta-Das intermixed oscillations.

SSSC-AM: A Unified Framework for Video Co-Segmentation by Structured Sparse Subspace Clustering with Appearance and Motion Features

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: Video co-segmentation refers to the task of jointly segmenting common objects appearing in a given group of videos. In practice, high-dimensional data such as videos can be conceptually thought as being drawn from a union of subspaces corresponding to categories rather than from a smooth manifold. Therefore, segmenting data into respective subspaces --- subspace clustering --- finds widespread applications in computer vision, including co-segmentation. State-of-the-art methods via subspace clustering seek to solve the problem in two steps: First, an affinity matrix is built from data, with appearance features or motion patterns. Second, the data are segmented by applying spectral clustering to the affinity matrix. However, this process is insufficient to obtain an optimal solution since it does not take into account the {\em interdependence} of the affinity matrix with the segmentation. In this work, we present a novel unified video co-segmentation framework inspired by the recent Structured Sparse Subspace Clustering ($\mathrm{S^{3}C}$) based on the {\em self-expressiveness} model. Our method yields more consistent segmentation results. In order to improve the detectability of motion features with missing trajectories due to occlusion or tracked points moving out of frames, we add an extra-dimensional signature to the motion trajectories. Moreover, we reformulate the $\mathrm{S^{3}C}$ algorithm by adding the affine subspace constraint in order to make it more suitable to segment rigid motions lying in affine subspaces of dimension at most $3$. Our experiments on MOViCS dataset show that our framework achieves the highest overall performance among baseline algorithms and demonstrate its robustness to heavy noise.

description: The most sensitive process able to probe the Majorana nature of neutrinos and discover Lepton Number Violation is the neutrino-less double beta decay. Thanks to the excellent energy resolution, efficiency and intrinsic radio-purity, cryogenic calorimeters are primed for the search for this process. A novel approach able to improve the sensitivity of the current experiments is the rejection of $α$ interactions, that represents the dominant background source. In TeO$_2$ calorimeters, $α$ particles can be tagged as, in contrast to electrons, they do not emit Cherenkov light. Nevertheless, the very low amount of detected Cherenkov light undermines the complete rejection of $α$ background. In this paper we compare the results obtained in previous measurements of the TeO$_2$ light yield with a detailed Monte Carlo simulation able to reproduce the number of Cherenkov photons produced in $β/γ$ interactions within the calorimeter and their propagation in the experimental set-up. We demonstrate that the light yield detectable from a $5\times5\times5$~cm$^{3}$ TeO$_2$ bolometer can be increased by up to 60% by increasing the surface roughness of the crystal and improving the light detector design. Moreover, we study the possibility to disentangle $α$, $β$ and $γ$ interactions, which represent the ultimate background source. Unfortunately $γ$ rejection is not feasible but $α$ rejection can be achieved exploiting high sensitivity light detectors.

description: Structural, interfacial, optical, and transport properties of large-area MoS2 ultra-thin films on BN-buffered silicon substrates fabricated using magnetron sputtering are investigated. A relatively simple growth strategy is demonstrated here that simultaneously promotes superior interfacial and bulk MoS2 properties. Few layers of MoS2 are established using X-ray reflectivity, diffraction, ellipsometry, and Raman spectroscopy measurements. Layer-specific modeling of optical constants shows very good agreement with first-principles calculations. Conductivity measurements reveal that few-layer MoS2 films are more conducting than many-layer films. Photo-conductivity measurements reveal that the sputter deposited MoS2 films compare favorably with other large-area methods. Our work illustrates that sputtering is a viable route for large-area device applications using transition metal dichalcogenides.

description: We have been studying spherically symmetric motions of gaseous stars with physical vacuum boundary governed either by the Euler-Poisson equations in the non-relativistic theory or by the Einstein-Euler equations in the relativistic theory. The problems are to construct solutions whose first approximations are small time-periodic solutions to the linearized problem at an equilibrium and to construct solutions to the Cauchy problem near an equilibrium. These problems can be solved when $1/(γ-1)$ is an integer, where $γ$ is the adiabatic exponent of the gas near the vacuum, by the formulation by R. Hamilton of the Nash-Moser theorem. We discuss on an application of the formulation by J. T. Schwartz of the Nash-Moser theorem to the case in which $1/(γ-1)$ is not an integer but sufficiently large.

EU Menu

description:   The project 'Evaluation, Review and Advice on methods and tools for EU Menu phase 2', with acronym ERA EU Menu, has been conducted by RIVM and the University of Porto (U.Porto) in a joint effort (EFSA grant: GP/EFSA/DATA/2021/03). The objective of the ERA EU-Menu project is to give advice to EFSA for an update of the EU menu guidance, based on an extensive literature review on methodologies and tools that are currently used in National Dietary Surveys, combined with an evaluation of the quality of data collected under the EU menu framework. Based on these different purposes, the ERA EU Menu project is divided into three work packages (WP): WP1: review on methods and tools; WP2: Evaluation of current data; WP3: Advise for EU-menu phase 3.

  This publication refers to WP2 'Evaluation of current data' activities, in which the project team aimed to (1) identify which are the most relevant data quality indicators related to EU Menu dietary surveys (presented in Annex A); (2) define what should be the statistical approach for evaluating the overall quality and associated factors of the EU Menu surveys; and finally (3) evaluate the quality and harmonization of the surveys in the EU Menu framework and the main associated factors (survey dimensions and countries' sociodemographic factors) (presented in the Report file).

  Data from thirty-one surveys conducted under EU Menu guidelines was used, considering the surveys' datasets and their methodological reports. Surveys were mapped based on a list of 96 quality indicators, which cover nine dimensions Sampling, Recruitment, Interviewer Training, Data Collection, Software Tools, Non-dietary Data Collection, Data Completeness, Data Analysis, and Reporting. An exploratory analysis was also conducted to examine how the survey dimensions impacted data quality in terms of missing data, food and recipe description, data reliability, the presence of outliers, and energy misreporting.

  Overall, most surveys adhered well to EFSA 2014 guidelines, achieving a commendable level of harmonization and compliance. However, some challenges persist, namely, the inaccurate use of definitions, missing information in the final reports, differences in the seasons coverage during data collection, and discrepancies in database sharing with EFSA. The dimensions that mostly impacted data quality were the sampling, training & supervision of interviewers and interview administration procedures (seasonality, interview duration). 

  This report describes in detail the analysis and results of quality indicators to inform recommendations for future survey rounds in the ERA EU Menu project's final deliverable.

description: The key challenge to improving performance in the age of Dark Silicon is how to leverage transistors when they cannot all be used at the same time. In modern SOCs, these transistors are often used to create specialized accelerators which improve energy efficiency for some applications by 10-1000X. While this might seem like the magic bullet we need, for most CPU applications more energy is dissipated in the memory system than in the processor: these large gains in efficiency are only possible if the DRAM and memory hierarchy are mostly idle. We refer to this desirable state as Dark Memory, and it only occurs for applications with an extreme form of locality. To show our findings, we introduce Pareto curves in the energy/op and mm$^2$/(ops/s) metric space for compute units, accelerators, and on-chip memory/interconnect. These Pareto curves allow us to solve the power, performance, area constrained optimization problem to determine which accelerators should be used, and how to set their design parameters to optimize the system. This analysis shows that memory accesses create a floor to the achievable energy-per-op. Thus high performance requires Dark Memory, which in turn requires co-design of the algorithm for parallelism and locality, with the hardware.

description: We present a new algorithm for locating a small cluster of points with differential privacy [Dwork, McSherry, Nissim, and Smith, 2006]. Our algorithm has implications to private data exploration, clustering, and removal of outliers. Furthermore, we use it to significantly relax the requirements of the sample and aggregate technique [Nissim, Raskhodnikova, and Smith, 2007], which allows compiling of "off the shelf" (non-private) analyses into analyses that preserve differential privacy.

description: By considering the 3-3-1 and the left-right symmetric models as low energy effective theories of the $SU(3)_C\otimes SU(3)_L\otimes SU(3)_R$~(for short $[SU(3)]^3$) gauge group, alternative versions of these models are found. The new neutral gauge bosons of the universal 3-3-1 model and its flipped versions are presented; also, the left-right symmetric model and its flipped variants are studied. Our analysis shows that there are two flipped versions of the universal 3-3-1 model, with the particularity that both of them have the same weak charges. For the left-right symmetric model we also found two flipped versions; one of them new in the literature which, unlike those of the 3-3-1, requires a dedicated study of its electroweak properties. For all the models analyzed, the couplings of the $Z'$ bosons to the standard model fermions are reported. The explicit form of the null space of the vector boson mass matrix for an arbitrary Higgs tensor and gauge group is also presented. In the general framework of the $[SU(3)]^3$ gauge group, and by using the LHC experimental results and EW precision data, limits on the $Z'$ mass and the mixing angle between $Z$ and the new gauge bosons $Z'$ are obtained. The general results call for very small mixing angles in the range $10^{-3}$ radians and $M_{Z'}>$ 2.5 TeV.
GJMS-type Operators on a compact Riemannian manifold: Best constants and Coron-type solutions

description: In this paper we investigate the existence of solutions to a nonlinear elliptic problem involving critical Sobolev exponent for a polyharmonic operator on a Riemannian manifold $M$. We first show that the best constant of the Sobolev embedding on a manifold can be chosen as close as one wants to the Euclidean one, and as a consequence derive the existence of minimizers when the energy functional goes below a quantified threshold. Next, higher energy solutions are obtained by Coron's topological method, provided that the minimizing solution does not exist. To perform this topological argument, we overcome the difficulty of dealing with polyharmonic operators on a Riemannian manifold and adapting Lions's concentration-compactness lemma. Unlike Coron's original argument for a bounded domain in $\mathbb{R}^{n}$, we need to do more than chopping out a small ball from the manifold $M$. Indeed, our topological assumption that a small sphere on $M$ centred at a point $p \in M$ does not retract to a point in $M\backslash \{ p \}$ is necessary, as shown for the case of the canonical sphere where chopping out a small ball is not enough.

Localizzazione del mitologico popolo delle donne guerriere Amazzoni ad Atlantide e nel Caucaso
Creators: name: Usai, Luigi

description:  

Questo studio interdisciplinare esamina la possibilità che il popolo mitologico delle Amazzoni abbia avuto le sue origini nella leggendaria Atlantide, identificata con il blocco sardo-corso, come descritto nei dialoghi di Platone. Successivamente, il mito delle Amazzoni potrebbe essersi trasferito nel Caucaso, una regione tradizionalmente considerata la loro patria dalle fonti storiche antiche. Attraverso un'analisi delle fonti classiche, mitologiche e archeologiche, il paper esplora la teoria secondo cui le Amazzoni potrebbero rappresentare una civiltà guerriera con radici in Atlantide, che si sarebbe diffusa o migrata nel Caucaso dopo la caduta della loro civiltà originaria. In particolare, si propone che il gruppo di Amazzoni prigioniere, fuggite dai loro rapitori, possa essere migrato nel Caucaso, decidendo di stabilirsi e fondare una nuova colonia. Questo spostamento avrebbe portato all'esportazione nel Caucaso della lingua, delle tradizioni e della cultura atlantidea, oggi identificata come "sarda".

description: The main idea of Gyrokinetic dynamical reduction consists in systematical removing of fastest scale of motion (the gyro motion) from plasma's dynamics, resulting in a considerable model simplification and gain of computing time. Gyrokinetic Maxwell-Vlasov system is broadly implemented in nowadays numerical experiments for modeling strongly magnetized plasma (both laboratory and astrophysical). Different versions of reduced set of equations exist depending on the construction of the Gyrokinetic reduction procedure and approximations assumed while their derivation. The purpose of this paper is to explicitly show the connection between the general second order gyrokinetic Maxwell-Vlasov system issued from the Modern Gyrokinetic theory derivation and the model currently implemented in global electromagnetic Particle in Cell code ORB5. Strictly necessary information about the Modern Gyrokinetic formalism is given together with the consistent derivation of the gyrokinetic Maxwell-Vlasov equations from the first principle of dynamics. Variational formulation of dynamics is also used for simultaneously obtaining the corresponding exact energy conservation law. The result of that explicit derivation is used for verification of the energy conservation diagnostics currently implemented in ORB5 code. This work subscribes into the context of codes verification project VeriGyro currently run in IPP Max Planck Institut in collaboration with others European institutions.

description: Transport measurements in inverted InAs/GaSb quantum wells reveal a giant spin-orbit splitting of the energy bands close to the hybridization gap. The splitting results from the interplay of electron-hole mixing and spin-orbit coupling, and can exceed the hybridization gap. We experimentally investigate the band splitting as a function of top gate voltage for both electron-like and hole-like states. Unlike conventional, noninverted two-dimensional electron gases, the Fermi energy in InAs/GaSb can cross a single spin-resolved band, resulting in full spin-orbit polarization. In the fully polarized regime we observe exotic transport phenomena such as quantum Hall plateaus evolving in $e^2/h$ steps and a non-trivial Berry phase.

description: The multi-band template analysis (MBTA) pipeline is a low-latency coincident analysis pipeline for the detection of gravitational waves (GWs) from compact binary coalescences. MBTA runs with a low computational cost, and can identify candidate GW events online with a sub-minute latency. The low computational running cost of MBTA also makes it useful for data quality studies. Events detected by MBTA online can be used to alert astronomical partners for electromagnetic follow-up. We outline the current status of MBTA and give details of recent pipeline upgrades and validation tests that were performed in preparation for the first advanced detector observing period. The MBTA pipeline is ready for the outset of the advanced detector era and the exciting prospects it will bring.
