Cooperative and parametric strategies for 3D electromagnetic inversion
Creators: name: McMillan, Michael S. G.
Publisher: name: University of British Columbia
Year: 2017

description: Airborne electromagnetic (AEM) data is commonly collected for detecting buried natural resources, and this technique is sensitive to subsurface electrical resistivity distributions. The subsequent process of 3D AEM inversion constructs a physical property model from this data in order to better understand the size and shape of potential hidden resources. This thesis is designed to develop practical strategies to improve 3D AEM inversion accuracy in geologic settings where AEM data sets produce inconsistent or unsatisfactory inversion results. In this research, two overarching problematic scenarios are examined. First, in regions where an AEM survey overlaps with other electromagnetic data sets, a novel cooperative approach is introduced. This method is first tested on synthetic data where instead of producing an inversion model from each data set, the cooperative algorithm finds one consistent 3D resistivity model with improved resolution. The approach is then applied to field data over a high-sulfidation epithermal gold deposit where similar improvements are observed. The second scenario relates to improving 3D AEM inversions over thin conductive anomalies, a common geophysical target for copper and gold deposits. A new parametric inversion is developed using skewed Gaussian ellipsoids to represent target bodies. The approach is general but applied to frequency and time-domain AEM data with one or multiple anomalies. Combined with a voxel algorithm, the parametric inversion forms a hybrid approach capable of resolving thin conductive targets with smooth surrounding features. This hybrid technique is tested on synthetic data over conductive targets in a resistive background, and consistently produces models that are easier to interpret compared to voxel inversions alone. Field examples from a volcanogenic massive sulfide and an orogenic gold deposit highlight the practical nature of this method to image conductive mineralization with increased precision. The thesis concludes by analyzing a setting where multiple spatially overlapping AEM data sets exist over narrow conductive anomalies. Here, parametric, cooperative and voxel inversions are applied together to generate a consistent 3D resistivity model with thin targets and smooth background features. This section includes a discussion about potential pitfalls of such an approach when incompatible field measurements are encountered.

description: Recently, the tachyon cosmology has been represented as dark energy model to support the current acceleration of the universe without phantom crossing. In this paper, we study the dynamics of the tachyon cosmology in which the field plays the role of tachyon field and also non--minimally coupled to the matter lagrangian. The model shows current universe acceleration and also phantom crossing in the future. Two cosmological tests are also performed to validate the model; the difference in the distance modulus and the model independent Cosmological Redshift Drift (CRD) test.

description: k-core percolation is an extension of the concept of classical percolation and is particularly relevant to understand the resilience of complex networks under random damage. A new analytical formalism has been recently proposed to deal with heterogeneous k-cores, where each vertex is assigned a local threshold k_i. In this paper we identify a binary mixture of heterogeneous k-core which exhibits a tricritical point. We investigate the new scaling scenario and calculate the relevant critical exponents, by analytical and computational methods, for Erdos-Renyi networks and 2d square lattices.

description: We study the acoustic scattering properties of a phononic crystal designed to behave as a gradient index lens in water, both experimentally and theoretically. The gradient index lens is designed using a square lattice of stainless-steel cylinders based on a multiple scattering approach in the homogenization limit. We experimentally demonstrate that the lens follows the graded index equations derived for optics by mapping the pressure intensity generated from a spherical source at 20 kHz. We find good agreement between the experimental result and theoretical modeling based on multiple scattering theory.

description: High energy accelerators may probe into dark matter and the seesaw neutrino mass scales if they are not much heavier than ~O(TeV). In the absence of supersymmetry, we extend a class of SO(10) models to predict well known cold dark matter candidates while achieving precision unification with experimentally testable proton lifetime. The most important prediction is a new radiative seesaw formula of Ma type accessible to accelerator tests while the essential small value of its quartic coupling also emerges naturally. This dominates over the high-scale seesaw contributions making a major impact on neutrino physics and dark matter, opening up high prospects as a theory of fermion masses.

The feasibility of observing coherent Rabi-like population oscillations at a Förster resonance between two cold Rydberg atoms is analyzed. Spectra and the fidelity of the Rydberg dipole blockade are calculated for various experimental conditions, including nonzero detuning from the Förster resonance and finite laser linewidth. The results are discussed in the context of quantum-information processing with Rydberg atoms.

Using their results, we prove analytically the equality of superconformal indices in some U(1)-gauge group theories related by the mirror symmetry. The proofs are based on the well known identities of the theory of $q$-special functions. We also suggest the general index formula taking into account the $U(1)_J$ global symmetry present for abelian theories.

description:

In the wake of the so-called refugee crisis, the ethical imperative to write about the predicament of refugees has become hard to ignore. However, many representational pitfalls are involved in this process. Can refugees relate their story in a way that does not trap them into the role of victims? Can authors that choose to tell these stories avoid appropriating these experiences? This article tackles these issues in a comparative fashion, taking its case studies and theoretical insights from both the Italian and British cultural context, focusing on Elvira Mujčić’s Consigli per essere un bravo immigrato, Alessandro Leogrande’s La frontiera, and the short stories collections Refugee Tales.

The resulting O(beta_0 alpha_s^2) correction to the Bbar -> X_sgamma branching ratio amounts to a relative shift of +0.12% (+0.27%) for a photon-energy cut of 1.6 GeV (1.0 GeV). We also comment on the potential size of resummation and non-perturbative effects related to Q_8.

This essay explores the nexus between translation and migration via two works of art that deal explicitly with the “migration crisis” in Europe and North America. Via Crucis is an art installation by Emily Jacir (2016) in the Chiesa di San Raffaele in Milan, while Tell Me How It Ends: An Essay in Forty Questions by Valeria Luiselli (2017) records the author’s reflections on the screening sessions of child asylum seekers after they have crossed the US-Mexico border. In both texts, translation is central to how the stories of migration are told and, this essay argues, it should be central also to the way in which they are read and received.

description: This paper deals with the numerical modeling of wave propagation in porous media described by Biot's theory. The viscous efforts between the fluid and the elastic skeleton are assumed to be a linear function of the relative velocity, which is valid in the low-frequency range. The coexistence of propagating fast compressional wave and shear wave, and of a diffusive slow compressional wave, makes numerical modeling tricky. To avoid restrictions on the time step, the Biot's system is splitted into two parts: the propagative part is discretized by a fourth-order ADER scheme, while the diffusive part is solved analytically. Near the material interfaces, a space-time mesh refinement is implemented to capture the small spatial scales related to the slow compressional wave. The jump conditions along the interfaces are discretized by an immersed interface method. Numerical experiments and comparisons with exact solutions confirm the accuracy of the numerical modeling. The efficiency of the approach is illustrated by simulations of multiple scattering.

description: We investigate numerically how accurately one could constrain the strengths of different short-range contributions to neutrino-less double beta decay in effective field theory. Depending on the outcome of near-future experiments yielding information on the neutrino masses, the corresponding bounds or estimates can be stronger or weaker. A particularly interesting case, resulting in strong bounds, would be a positive signal of neutrino-less double beta decay that is consistent with complementary information from neutrino oscillation experiments, kinematical determinations of the neutrino mass, and measurements of the sum of light neutrino masses from cosmological observations. The keys to more robust bounds are improvements of the knowledge of the nuclear physics involved and a better experimental accuracy.

The aim of my contribution is to use statements by Jakob Arjouni himself, as well as a collage of the biographical data on Kemal Kayankaya scattered throughout the five crime novels, to show that while the serial hero has developed a bicultural self-confidence, often stylized as a metaphor of his cultural hybridity, more importantly he takes a post-integrative perspective, resulting from his gradual assimilation into German culture and society which began in his childhood and was completed in the course of his adolescence.

Characteristics of estrous behaviour in heifers and lactating cows and its associations with fertility
Creators: name: Figueiredo Silper, Bruna
Publisher: name: University of British Columbia
Year: 2017

description: Detection of estrus in dairy cows is challenging, partly because of poor behavioural expression. Automated activity monitors allow quantification of estrus expression based on restlessness. The main goals of this thesis were to use automated measurements and visual observation of behaviour to increase understanding of estrus characteristics, variation among animals, risk factors for poor expression, and its association with fertility. In the first study, the behaviour of heifers was video-recorded and activity peaks were identified from accelerometer data; estrus was validated by ovarian ultrasonography. Chin rest, sniff, back mount, crossover, and follow had the largest increase in frequency during estrus. Estrus relative increase in walking activity (290 ± 160%) and duration (14 ± 4 h) varied greatly and were affected by estrus order, season and time of the day. The second study investigated how estrus affected automated measurements of lying and standing behaviour, a less explored aspect of estrus. At estrus, bout frequency was lower, daily standing time was greater, and heifers stood uninterruptedly for twice longer than at baseline. Relative changes in standing behaviour at estrus were smaller for estrus starting between 1200 h and 0300 h. The third experiment investigated the agreement between estrus characteristics in heifers fitted with two accelerometers. Both systems were precise (PPV = 84.7% [Heatime] and 98.7% [IceTag]) and provided similar characterization and timing. Plasma estradiol was not correlated with follicle diameter, duration, intensity, or presence of estrus signs. Finally, estrus lying behaviour of lactating cows and its associations with fertility were studied. Daily lying time and bout frequency were reduced at estrus (65 ± 21% and 65 ± 24% of baseline). Ovulation and pregnancy at d 32 after AI were 4.9 and 1.6 times more likely if estrus lying time was < 75% of baseline. Collectively, results suggest potential application of lying behaviour towards fertility prediction. We have also highlighted features such as variability, risk factors and basal activity that can contribute to assessment of methods and practices for increased expression. Additional future directions include investigation of physiological bases of estrus-fertility association and real-time applications of characterization data.

This article addresses a comparatively neglected corpus of Italian travel and migrant writing in Mexico, ranging from Luigi Bruni’s Attraverso il Messico (1890) to Emilio Cecchi’s Messico (1932). It does so from the methodological angle of nation-making and through the seemingly counter-intuitive prism of Italian Orientalism(s). This article focuses on two key moments of both Italian and Mexican history: Post-Unification/Porfiriato and Ventennio/Post-Revolution. The discussion revolves around the problematization of the construction of an Otherized subalternity as a way for the emerging elites to discursively develop and circulate their worldview.

In her poetry collection falsche freunde the German-speaking artist Uljana Wolf develops a translinguale Lyrik, a poetic voice dwelling on a linguistic and geographical border zone. Building on Emily Apter’s concepts of untranslatability, this paper investigates how Wolf’s structural and thematic checkpoints instil a strong political commitment into her poetry. Furthermore, this engagement is here interpreted as the expression of the paradigm of the postmigrantische Gesellschaft. Finally, the paper argues that through the choice of the term ‘alien’ over the category ‘fremd’ Wolf suggests an innovative shift in the representation of migratory dynamics, from their cultural dimension to their biopolitical significance.

description: The fate of heavy quarkonia states has been investigated in QCD at high temperature when the plasma has a small momentum space anisotropy within a quasi-particle model. A real time static potential has been obtained from a Hard thermal loop expression for the gluon self-energy, by employing the quasi-parton equilibrium distribution functions extracted from hot QCD equations of state of $O(g^5)$ and $O(g^6\ln(1/g))$. Employing the potential, quarkonia melting has been studied. It is found that the equations of state and the momentum anisotropy cause significant modifications in the screening properties of the plasma.

description: We report magneto-transport measurements in wide GaAs quantum wells with tunable density to probe the stability of the fractional quantum Hall effect at filling factor $ν= $ 5/2 in the vicinity of the crossing between Landau levels (LLs) belonging to the different (symmetric and antisymmetric) electric subbands. When the Fermi energy ($E_F$) lies in the excited-state LL of the symmetric subband, the 5/2 quantum Hall state is surprisingly stable and gets even stronger near this crossing, and then suddenly disappears and turns into a metallic state once $E_F$ moves to the ground-state LL of the antisymmetric subband. The sharpness of this disappearance suggests a first-order transition.

description: In this paper we investigate electromagnetic interactions for simplest massive mixed symmetry field. Using frame-like gauge invariant formulation we extend Fradkin-Vasiliev procedure, initially proposed for investigation of gravitational interactions for massless particles in AdS space, to the case of electromagnetic interactions for massive particles leaving in (A)dS space with arbitrary value of cosmological constant including flat Minkowski space. At first, as an illustration of general procedure, we re-derive our previous results on massive spin 2 electromagnetic interactions and then we apply this procedure to massive mixed symmetry field. These two cases are just the simplest representatives of two general class of fields, namely completely symmetric and mixed symmetry ones, and it is clear that the results obtained admit straightforward generalization to higher spins as well.

description:

The present article analyses the novel Gefährliche Verwandtschaft by German-Turkish writer Zafer Şenocak. It aims to reconstruct the author’s perspective on debates on migration and integration and to show in which way this affects the genesis of authorship represented in the novel. According to the thesis presented in this article, Gefährliche Verwandtschaft is first of all a novel about identity politics in newly reunited Germany. As a result, it also deals with historical perceptions and interpretations of the past. This goes to show that the value of the novel lies in its provocative questioning of memory culture and politics in Germany in the 1990s and of the consequences of an increasingly institutionalized and ritualized remembrance of National Socialism for the perception of migration.

description: Die Coronavirus-Pandemie hat ein Brennglas auf eine Reihe von Problemen des aktuellen wissenschaftlichen Kommunikationssystems gerichtet. Darunter ist auch die Auffindbarkeit wissenschaftlicher Erkenntnisse: mehr als 200.000 Publikationen wurden zu dem Thema in kurzer Zeit veröffentlicht. Gängige Suchmaschinen, die unstrukturierte Ergebnislisten bereitstellen, können mit dieser Wissensexplosion nicht umgehen: sie bieten weder einen Überblick über die Ergebnisse noch die erforderlichen Kontextinformationen, um die Ressourcen evaluieren zu können.
 Open Knowledge Maps hat es sich zur Aufgabe gemacht, Sichtbarkeit und Auffindbarkeit wissenschaftlicher Erkenntnisse dramatisch zu erhöhen. Der gemeinnützige Verein entwickelt dafür ein offenes, visuelles und Community-gesteuertes System. Anstelle von Listen kommen Wissenslandkarten (Knowledge Maps) zum Einsatz. Wissenslandkarten bieten einen sofortigen Überblick über ein Feld, da sie die Hauptbereiche und die zu den einzelnen Bereichen gehörenden Dokumente auf einen Blick anzeigen. Mit BASE als Hauptdatenquelle baut Open Knowledge Maps auf Open Access-Infrastruktur auf und erhöht die Sichtbarkeit der darin enthaltenen Inhalte, z.B. aus institutionellen Repositorien oder aus Preprint-Archiven. Dies umfasst viele Quellen und Dokumenttypen, die von kommerziellen Produkten nicht indiziert werden.
 In unserem Vortrag stellen wir das brandneue Custom-Services-Modell vor, welches gemeinsam mit der Community entwickelt wurde. Das Modell ermöglicht es Institutionen, ihre Discovery-Angebote mit visuellen Suchkomponenten von Open Knowledge Maps zu erweitern. Diese werden wahlweise als Cloud-Komponenten eingebunden oder können als Open Source-Software am eigenen Server installiert werden. Die Komponenten sind adaptierbar, einschließlich der Möglichkeit, die Datenbasis auf die eigenen Bestände zu beschränken. Jede Wissenslandkarte hat eine PID und kann wiederum in andere Websites eingebettet werden, z.B. zu Präsentations- und Disseminationszwecken. Wie alle Angebote von Open Knowledge Maps werden auch die Custom Services kostenlos und als offene Infrastruktur bereitgestellt. Um die Infrastruktur zu finanzieren und aufrechtzuerhalten, betreiben wir ein Crowdsourcing-Modell mit Fördermitgliedern. Fördermitglieder werden Teil der Governance der Organisation und sind direkt in Entscheidungsprozesse um die technische Roadmap eingebunden.

description: Alopecia Areata (AA) ist eine T-Zell-vermittelte Autoimmunerkrankung des Haarfollikels. Erstmals wurden Keratine als Autoantigene der AA und der Mechanismus der CD44- sowie CD44v10-Blockade identifiziert. Die Vakzinierung mit Keratinen induzierte eine milde AA in Mäusen mit einem signifikanten Anstieg Keratin-spezifischer T-Zellen. Die Applikation in tolerogener Form verzögerte die AA-Progression durch Anergieinduktion in Keratin-spezifischen T-Zellen und Expansion regulatorischer T-Zellen.
Le vite dell’Altro

description:

This article examines the recurring mixture of fiction and autobiographical themes in the work of Bosnian-American writer Aleksandar Hemon, whose writings can be placed close to the literary genre known as Autofiction. These traits occur also in his latest production, exemplified by The Book of My Lives (2013) and My Parents / This Does Not Belong To You (2019). In these two books the attention paid by the author to his relatives’ experiences may led to a comparison with the autofiction subgenre defined by A.K. Mortimer as ‘Allofiction’. Studying these features, my intent is to analyze how Hemon’s stylistic choices have been affected by his condition of other both in the USA and postwar Bosnia.

Migrant and Minority Nostalgia in Karen Tei Yamashita’s Circle K Cycles
Creators: name: Micheli, Grazia
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2020

description:

This essay explores the concept of nostalgia through an analysis of Circle K Cycles (2001), a creative (auto)ethnographic text in which the Japanese American writer Karen Tei Yamashita portrays Japanese Brazilians’ ethnic return migration to Japan in the 1980s and 1990s. In the face of social marginalisation and the hegemonic pressures of Japanese culture to conform to a standard of ‘pure Japaneseness’, Japanese Brazilians reinforce their attachment to Brazil, which they express in the form of nostalgia, or saudade. Yet Yamashita criticises any idea of cultural separateness and ‘purity’, both by experimenting with form and by describing phenomena of cultural hybridisation.

description: We investigate quantum phase transitions occurring in a system of strongly interacting ultracold bosons in a 1D optical lattice. After discussing the commensurate-incommensurate transition, we focus on the phases appearing at incommensurate filling. We find a rich phase diagram, with superfluid, supersolid and solid (kink-lattice) phases. Supersolids generally appear in theoretical studies of systems with long-range interactions; our results break this paradigm and show that they may also emerge in models including only short-range (contact) interactions, provided that quantum fluctuations are properly taken into account.
Confronting Dark Energy Models using Galaxy Cluster Number Counts

description: The mass function of cluster-size halos and their redshift distribution are computed for 12 distinct accelerating cosmological scenarios and confronted to the predictions of the conventional flat $Λ$CDM model. The comparison with $Λ$CDM is performed by a two-step process. Firstly, we determine the free parameters of all models through a joint analysis involving the latest cosmological data, using SNe type Ia, the CMB shift parameter and BAO. Apart from a brane world inspired cosmology, it is found that the derived Hubble relation of theremaining models reproduce the $Λ$CDM results approximately with the same degree of statistical confidence. Secondly, in order to attempt distinguish the different dark energy models from the expectations of $Λ$CDM, we analyze the predicted cluster-size halo redshift distribution on the basis of two future cluster surveys: (i) an X-ray survey based on the {\tt eROSITA} satellite, and (ii) a Sunayev-Zeldovich survey based on the South Pole Telescope. As a result, we find that the predictions of 8 out of 12 dark energy models can be clearly distinguished from the $Λ$CDM cosmology, while the predictions of 4 models are statistically equivalent to those of the $Λ$CDM model, as far as the expected cluster mass function and redshift distribution are concerned. The present analysis suggest that such a technique appears to be very competitive to independent tests probing the late time evolution of the Universe and the associated dark energy effects.

Transformations of Gender Identities and Roles in Novels of Flight and Exile by Olga Grjasnowa and Shida Bazyar
Creators: name: Kofer, Martina
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2020

description:

Over the last several years, cultural studies scholars in Germany have closely examined the subject of refugees in recent German literature, focusing largely on aspects of spatial theory, the causes of migration and the figure of the refugee. However, while the migrant as cultural Other has received extensive attention, gender issues remain largely underrepresented. This contribution explores the ways in which forced migration, due mostly to war and violence, affects the gender identities and roles of characters in the novels of Olga Grjasnowa (Gott ist nicht schüchtern) and Shida Bazyar (Nachts ist es leise in Teheran).

description: We investigate the influence of deformation on the possible occurrence of long-lived $K$ isomers in Hf isotopes around N=116, using configuration-constrained calculations of potential-energy surfaces. Despite having reduced shape elongation, the multi-quasiparticle states in $^{186,188}$Hf remain moderately robust against triaxial distortion, supporting the long expected occurrence of exceptionally long-lived isomers. The calculations are compared with available experimental data.

Implementation and effectiveness evaluation of a school-based daily physical activity policy in British Columbia elementary schools
Creators: name: Weatherson, Katie Alayna
Publisher: name: University of British Columbia
Year: 2017

description: This thesis comprises three integrated studies exploring the implementation and effectiveness of a school-based Daily Physical Activity (DPA) policy in elementary schools. The purposes of the three manuscripts were to: (i) summarize the implementation and effectiveness literature on DPA policies across Canada, (ii) explore the factors that affect implementation of the DPA policy during instructional time by teachers in British Columbia (BC), and (iii) determine if BC students are accumulating more physical activity and less sedentary behaviour during the school day when they are given additional opportunities to be active during instructional time compared to only non-instructional opportunities. Study 1 was a scoping review that summarized the implementation and effectiveness research of DPA policies across Canada and examined the barriers and facilitators to DPA policy implementation using the Theoretical Domains Framework (TDF). The findings revealed inconsistencies in DPA implementation and effectiveness and the majority of factors that affect implementation related to the Environmental context and resources, Beliefs about the consequences and Social influences. Study 2 used teacher interviews and the TDF to examine teachers’ barriers and facilitators to the implementation of the DPA policy in one BC school district. The first three domains of this study were comparable to the findings from Study 1. Study 3 used mixed methods to examine how teachers implement the DPA policy and compared the differences in children’s physical activity and sedentary behaviour at school based on DPA implementation approach. Children who were given additional PA opportunities during instructional time were more active and less sedentary than children who were only given non-instructional time to be active; however, neither group met the DPA guidelines. Collectively, this research has provided evidence suggesting that current implementation approaches differ by teacher and create variations in children’s physical activity levels at school. Based on this research, evidence-based intervention strategies can be employed to modify barriers and enhance facilitators associated with DPA policy implementation and improve the effectiveness of this policy. Future interventions targeting the theoretically relevant barriers are suggested as possible next steps to enhance the implementation and effectiveness of the DPA policy in BC.
„Bildung“ (Herder) und „Cultur“ (Adelung) im Vergleich
Creators: name: Laudin, Gérard
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia

description:

“Bildung” and “Kultur” are among the key terms of the German Enlightenment, and appear in various hierarchical forms in the late 18th century. In Adelung’s Versuch einer Geschichte der Cultur des menschlichen Geschlechts (1782), which partly draws on Herder’s Auch eine Philosophie der Geschichte zur Bildung der Menschheit (1774), the term Cultur refers to a social phenomenon that subsumes “refinement” (Verfeinerung), “Enlightenment” (Aufklärung) and “abilities” (Fähigkeiten). Adelung’s concept of culture is tightly linked to his interpretation of human history, which differs both from that of the largely politically oriented universal histories of his time, and from that of the anthropologically based “philosophies of history” (Iselin, Herder, Kant). For Adelung, culture is produced by “crowds in confined spaces” and thus appears as a quantitative phenomenon, as opposed to the qualitative elements such as power (Kraft) and fermentation (Gärung) that determine the course of history in Herder’s philosophy of history of 1774. Cultur emerges from a balance that comes about when the material and non-material components of a given culture are “in the most exact proportion” to each other. The idea of the “Maximum” formulated in Herder’s Ideen zur Philosophie der Geschichte der Menschheit (1784), which is described as “a climax” that every nation reaches in its own way, appears to be developed critically as a counterpart to Adelung’s concept of balance.

description: The scope of this essay is to provide a brief overview of the history and legacy of the book Life between buildings: Using Public Space written by Jan Gehl, Danish architect and urban consultant, renowned for his pioneering work towards the promotion of human-centered urban design. The paper starts with explaining the concept of the Human Scale in urbanism studies, both as a means to view the city focusing on what is happening at ground level and as a design priority. It continues with the story of the making of the book, back in 1971, and the impact it has had in establishing the human-centered approach in urban design as a rising trend, especially in the last two decades. The essay concludes with the three major lessons that we can extract from the book: (1) knowledge about human senses; (2) learning from observing; and (3) putting people first.
