description: We measure the Ca II 8542 line strength in 3360 stars along three lines-of-sight in the Galactic bar: (l,b) ~ (+/-5.0,-3.5) and Baade's Window, using Fabry-Perot (FP) absorption line spectroscopy. This is the first attempt to show that reliable absorption line strengths can be measured using FP spectroscopy. The Ca II 8542 line is a good indicator of metallicity and its calibration to [Fe/H] is determined for globular cluster red giants in previous investigations. We derive such a calibration for the bulge giants and use it to infer metallicities for our full red clump sample (2488 stars) at all three lines-of-sight. We present the stellar metallicity distributions along the major axis of the bar. We find the mean [Fe/H] = -0.09 +/- 0.04 dex in Baade's Window, and find the distribution in this field to agree well with previous works. We find gradients in the mean metallicity and its dispersion w.r.t Baade's WIndow of -0.45 and -0.20 dex respectively at l = +5.5, and of -0.10 dex and -0.20 dex at l = -5.0. We detect a signature of a possible tidal stream at l = +5.5, in both our velocity and metallicity distributions. Its radial velocity indicates that it is not associated with the Sagittarius stream. We also measure the metallicity of a bulge globular cluster NGC 6522 in our Baade's Window field to be -0.90 +/- 0.10 dex, in agreement with recent measurements of Zoccali et al. (2008). This agreement demonstrates the reliability of our metallicity measurements.

description: When an off-resonant light field is coupled with atomic spins, its polarization can rotate depending on the direction of the spins via a Faraday rotation which has been used for monitoring and controlling the atomic spins. We observed Faraday rotation by an angle of more than 10 degrees for a single 1/2 nuclear spin of 171Yb atom in a high-finesse optical cavity. By employing the coupling between the single nuclear spin and a photon, we have also demonstrated that the spin can be projected or weakly measured through the projection of the transmitted single ancillary photon.

description: We present computer simulations of liquid and solid phases of condensed methane at pressures below 25 GPa, between 150 and 300 K, where no appreciable molecular dissociation occurs. We used molecular dynamics (MD) and metadynamics techniques, and empirical potentials in the rigid molecule approximation, whose validity was confirmed a posteriori by carrying out it ab initio MD simulations for selected pressure and temperature conditions. Our results for the melting line are in satisfactory agreement with existing measurements. We find that the fcc crystal transforms into a hcp structure with 4 molecules per unit cell (B phase) at about 10 GPa and 150 K, and that the B phase transforms into a monoclinic high pressure phase above 20 GPa. Our results for solid/solid phase transitions are consistent with those of Raman studies but the phase boundaries estimated in our calculations are at higher pressure than those inferred from spectroscopic data.

subject: FOS: Physical sciences

description: Recent experiments on imbalanced Fermi gases have raised interest in the physics of an impurity immersed in a Fermi sea, the so-called Fermi polaron. In this letter, a simple theory is devised to describe dilute Fermi-polaron ensembles corresponding to the normal phase of an imbalanced Fermi gas. An exact formula is obtained for the dominant interaction between polarons, expressed solely in terms of a single polaron parameter. The physics of this interaction is identified as a signature of the Pauli exclusion principle.

NGC 300 OT2008-1 As a Scaled-Down Version of the Eta Carinae Great Eruption

description: We propose that the intermediate luminosity optical transient NGC 300 OT2008-1 was powered by a mass transfer episode from an extreme Asymptotic Giant Branch star to a Main Sequence companion. We find a remarkable similarity of the shapes of the light curves of the several months long NGC 300 OT2008-1 outburst, of the three months long 2002 enigmatic outburst of the B star V838 Mon, and the twenty-years long Great Eruption of the massive binary system Eta Carinae that occurred in the 19th century. Their similar decline properties hint to a common energy source: a gravitational energy that is released by accretion onto a main sequence star. These events populate a specific strip in the total energy vs. outburst duration diagram. The strip is located between novae and supernovae. We add recent transient events to that diagram and find them to occupy the same strip. This suggests that some intermediate luminosity optical transients are powered by accretion onto a compact object (not necessarily a main sequence star). These transients are expected to produce bipolar ejecta as a result of the geometry of the accretion process.

description: We present a systematic temporal and spectral study of all Swift-XRT observations of GRB afterglows discovered between 2005 January and 2007 December. After constructing and fitting all light curves and spectra to power-law models, we classify the components of each afterglow in terms of the canonical X-ray afterglow and test them against the closure relations of the forward shock models for a variety of parameter combinations. The closure relations are used to identify potential jet breaks with characteristics including the uniform jet model with and without lateral spreading and energy injection, and a power-law structured jet model, all with a range of parameters. With this technique, we survey the X-ray afterglows with strong evidence for jet breaks (~12% of our sample), and reveal cases of potential jet breaks that do not appear plainly from the light curve alone (another ~30%), leading to insight into the missing jet break problem. Those X-ray light curves that do not show breaks or have breaks that are not consistent with one of the jet models are explored to place limits on the times of unseen jet breaks. The distribution of jet break times ranges from a few hours to a few weeks with a median of ~1 day, similar to what was found pre-Swift. On average Swift GRBs have lower isotropic equivalent gamma-ray energies, which in turn results in lower collimation corrected gamma-ray energies than those of pre-Swift GRBs. Finally, we explore the implications for GRB jet geometry and energetics.

Nonaxisymmetric Rossby Vortex Instability with Toroidal Magnetic Fields in Radially Structured Disks

Year: 2009

description: We investigate the global nonaxisymmetric Rossby vortex instability in a differentially rotating, compressible magnetized accretion disk with radial density structures. Equilibrium magnetic fields are assumed to have only the toroidal component. Using linear theory analysis, we show that the density structure can be unstable to nonaxisymmetric modes. We find that, for the magnetic field profiles we have studied, magnetic fields always provide a stabilizing effect to the unstable Rossby vortex instability modes. We discuss the physical mechanism of this stabilizing effect. The threshold and properties of the unstable modes are also discussed in detail. In addition, we present linear stability results for the global magnetorotational instability when the disk is compressible.

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Myelin figures are interfacial structures formed when certain surfactants swell in excess water. Here, I present data and model calculations suggesting myelin formation and growth is due to the fluid flow of surfactant, driven by the hydration gradient at the dry surfactant/water interface; a simple model based on this idea qualitatively reproduces the various myelin growth behaviors observed in different experiments. From a detailed experimental observation of how myelins develop from a planar precursor structure, I identify a mechanical instability that may underlie myelin formation. These results indicate the mixed mechanical character of the surfactant lamellar structure, where fluid and elastic properties coexist, is what enables the formation and growth of myelins.

Examining How an Inclusive Economy Approach Can Inform Economic Development in Urban and Rural Alberta
Creators: Mayan, Maria
Publisher: name: University of Alberta Library
Year: 2020

SSHRC IG awarded 2021: Adopting a community-based participatory research approach, this project will use a comparative case study methodology to examine how an inclusive economy approach is being used to inform economic development in Edmonton (urban) and Drayton Valley (rural). This will be accomplished by: 1) examining the implementation of each community's strategies to understand the facilitators and barriers similar and unique to each, as well as new patterns across the cases; 2) assessing the initial effects of each community's strategies, with particular focus on (in)equity of distribution; and 3) engaging with each community's stakeholders from community-based organizations, varying levels of government, industry, and educational institutions to mobilize learning and inform research, policy and practice. With an interpretivist lens, we will draw on a number of qualitative and quantitative methods to achieve our project objectives, including participant observation, interviews, and surveys. Data will be analyzed iteratively using descriptive and inferential statistics and constant comparison with particular attention to intersectional axis of power and the distribution of effects. Through this project we can begin to address a significant gap in the research literature and generate knowledge to inform research, policy and practice.

description: Τα πλοία, ως Ιεραρχικά Δομημένες Οργανώσεις χαρακτηρίζονται από αυστηρές και πολλές φορές άκαμπτες δομές και σχέσεις μεταξύ της Διοίκησης και των εργαζομένων. Οι Ιεραρχικές οργανώσεις παρουσιάζουν συγκεκριμένα χαρακτηριστικά γνωρίσματα και αποτελούν ένα εξαιρετικά ιδιαίτερο και απαιτητικό περιβάλλον για τους εργαζομένους. Οι ναυτικοί όπως και οι υπόλοιποι εργαζόμενοι, σχηματίζουν τυπικές ομάδες σύμφωνα με το οργανόγραμμα, αλλά και άτυπες ομάδες που δεν μπορούν εκ των προτέρων να σχεδιαστούν και να προβλεφθούν. Οι άτυπες αυτές ομάδες, ειδικότερα στα πλοία, λόγω της φύσης του επαγγέλματος των ναυτικών, που χαρακτηρίζεται από συχνή εναλλαγή των εργαζομένων, άρα και των συμμετεχόντων στις άτυπες ομάδες, παρουσιάζουν εξαιρετικό ενδιαφέρον όσον αφορά τη μελέτη των αιτιών που οδηγούν στον σχηματισμό τους, τον τρόπο λειτουργίας τους, τα συναισθήματα που προκαλούν στους συμμετέχοντες, την επίδραση τους στη συμπεριφορά των πληρωμάτων και κυρίως για το αν τελικά η ύπαρξη τους αφήνει θετικό ή αρνητικό αντίκτυπο στο πλοίο ως «Οργανισμό». Προκειμένου να διαπιστωθούν τα ανωτέρω διενεργήθηκε μια μικρή ερευνητική διαδικασία μέσω ερωτηματολογίου, όπου και καταγράφηκαν οι απόψεις των ίδιων των ναυτικών, σχετικά με τις άτυπες ομάδες. Από τη θεωρία που αναπτύχθηκε και τα ερευνητικά ευρήματα διαπιστώθηκαν αρκετές συμπτώσεις αλλά και ουσιώδεις διαφορές που επαληθεύουν τόσο τη χρησιμότητα και σπουδαιότητα της ύπαρξης των άτυπων ομάδων, όσο και τις ιδιαιτερότητες που αυτές παρουσιάζουν όταν σχηματίζονται σε ένα κλειστό και Ιεραρχικά δομημένο οργανισμό, όπως είναι το πλοίο.

description: We explain how to implement, in the context of projected entangled-pair states (PEPS), the general procedure of fermionization of a tensor network introduced in [P. Corboz, G. Vidal, Phys. Rev. B 80, 165129 (2009)]. The resulting fermionic PEPS, similar to previous proposals, can be used to study the ground state of interacting fermions on a two-dimensional lattice. As in the bosonic case, the cost of simulations depends on the amount of entanglement in the ground state and not directly on the strength of interactions. The present formulation of fermionic PEPS leads to a straightforward numerical implementation that allowed us to recycle much of the code for bosonic PEPS. We demonstrate that fermionic PEPS are a useful variational ansatz for interacting fermion systems by computing approximations to the ground state of several models on an infinite lattice. For a model of interacting spinless fermions, ground state energies lower than Hartree-Fock results are obtained, shifting the boundary between the metal and charge-density wave phases. For the t-J model, energies comparable with those of a specialized Gutzwiller-projected ansatz are also obtained.

Immunization of networks with community structure

description: In this study, an efficient method to immunize modular networks (i.e., networks with community structure) is proposed. The immunization of networks aims at fragmenting networks into small parts with a small number of removed nodes. Its applications include prevention of epidemic spreading, intentional attacks on networks, and conservation of ecosystems. Although preferential immunization of hubs is efficient, good immunization strategies for modular networks have not been established. On the basis of an immunization strategy based on the eigenvector centrality, we develop an analytical framework for immunizing modular networks. To this end, we quantify the contribution of each node to the connectivity in a coarse-grained network among modules. We verify the effectiveness of the proposed method by applying it to model and real networks with modular structure.

description: Emitted from aircraft travelling at supersonic speeds, screech tones are high-amplitude, discrete-frequency, and can damage the surrounding aircraft structure. To mitigate their impacts, a better understanding of how they arise is required. This thesis models the screech tones present in aircraft with a round twin-exhaust configuration. New insights into their generation, and the behaviours of the components generating them, are presented. In particular for low supersonic velocities, and as the two round exhausts are brought closer together.
Yukawa Couplings and Effective Interactions in Gauge-Higgs Unification

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The wave functions and Yukawa couplings of the top and bottom quarks in the SO(5) x U(1) gauge-Higgs unification model are determined. The result is summarized in the effective interactions for \hat θ_H(x) = θ_H + H(x)/f_H where θ_H is the Wilson line phase and H(x) is the 4D Higgs field. The Yukawa, WWH and ZZH couplings vanish at θ_H = \onehalf π. There emerges the possibility that the Higgs particle becomes stable.

STRUCTURAL AND FUNCTIONAL CONSEQUENCES OF P63 MUTATIONS CAUSATIVE OF AEC SYNDROME
Creators: name: RUSSO, CLAUDIA
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: p63, a p53 family member, is a tetrameric transcription factor required for the development and differentiation of stratified epithelia. Heterozygous mutations in p63 are causative of a group of autosomal dominant human disorders characterized by ectodermal dysplasia, orofacial clefting and limb malformations. More specifically, mutations clustering in the C-terminal domain of p63 cause Ankyloblepharon-Ectodermal defects-Cleft lip/palate (AEC) syndrome, a life-threatening disorder characterized by severe extended skin erosions. Here we show that multiple AEC-associated p63 mutations lead to protein misfolding and aggregation, as observed also in human keratinocytes isolated from an AEC patient and in mouse keratinocytes obtained from a conditional knock-in mouse model for AEC syndrome, recently generated in our laboratory, that phenocopies the skin clinical features found in human patients. In AEC mice the aggregated p63 mutant protein causes an impaired expression of endogenous p63 target genes, among which are keratins and desmosomal proteins involved in cell adhesion and in mechanical resistance, leading to severe skin fragility and erosions. Importantly, we found that abolishing the aggregation of p63, by introducing mutations that drastically reduce the aggregation propensity of AEC mutants, allowed to rescue p63 transcriptional functions, thus suggesting that impaired p63 transactivation activity is uniquely associated in AEC syndrome with exposure of aggregation-prone sequences. In addition, our studies focused on the therapeutic potential of these findings and suggested possible approaches to treat the AEC syndrome based on targeting and strengthening the endogenous protein disaggregation machinery or using drugs designed to chemically assist the correct folding of the mutant protein.

description: Magnetic and superconducting instabilities in the two-dimensional t-t'-Hubbard model are discussed within a functional renormalization group approach. The fermionic four-point vertex is efficiently parametrized by means of partial bosonization. The exchange of composite bosons in the magnetic, charge density and superconducting channels accounts for the increase of the effective couplings with increasing length scale. We compute the pseudocritical temperature for the onset of local order in various channels.

description: We seek to understand the impact on shape estimators obtained from circular and elliptical shapelet models under two realistic conditions: (a) only a limited number of shapelet modes is available for the model, and (b) the intrinsic galactic shapes are not restricted to shapelet models. We create a set of simplistic simulations, in which the galactic shapes follow a Sersic profile. By varying the Sersic index and applied shear, we quantify the amount of bias on shear estimates which arises from insufficient modeling. Additional complications due to PSF convolution, pixelation and pixel noise are also discussed. Steep and highly elliptical galaxy shapes cannot be accurately modeled within the circular shapelet basis system and are biased towards shallower and less elongated shapes. This problem can be cured partially by allowing elliptical basis functions, but for steep profiles elliptical shapelet models still depend critically on accurate ellipticity priors. As a result, shear estimates are typically biased low. Independently of the particular form of the estimator, the bias depends on the true intrinsic galaxy morphology, but also on the size and shape of the PSF. As long as the issues discussed here are not solved, the shapelet method cannot provide weak-lensing measurements with an accuracy demanded by upcoming missions and surveys, unless one can provide an accurate and reliable calibration, specific for the dataset under investigation.

Tidal alignments as a contaminant of redshift space distortions

description: We investigate the effect of orientation-dependent selection effects on galaxy clustering in redshift space. It is found that if galaxies are aligned by large-scale tidal fields, then these selection effects give rise to a dependence of the observed galaxy density on the local tidal field, in addition to the well-known dependences on the matter density and radial velocity gradient. This alters the galaxy power spectrum in a way that is different for Fourier modes parallel to and perpendicular to the line of sight. These tidal galaxy alignments can thus mimic redshift space distortions, and thus result in a bias in the measurement of the velocity power spectrum. If galaxy orientations are affected only by the local tidal field, then the tidal alignment effect has exactly the same scale and angular dependence as the redshift space distortions in the linear regime, so it cannot be projected out or removed by masking small scales in the analysis. We consider several toy models of tidal alignments and orientation-dependent selection, normalize their free parameter (an amplitude) to recent observations, and find that they could bias the velocity amplitude f(z)G(z) by 5--10 per cent in some models, although most models give much smaller contamination. We conclude that tidal alignments may be a significant systematic error in redshift space distortion measurements that aim to test general relativity via the growth of large-scale structure. We briefly discuss possible mitigation strategies.

'OLTRE IL BADANTATO?' THE DYNAMIC EVOLUTION OF THE ITALIAN LONG-TERM CARE REGIME: AN AGENCY BASED APPROACH.
Creators: name: SALIS, ESTER
Publisher: name: Universit� degli Studi di Milano
Year: 2015

description: Is there identifiable patterns of occupational upgrading in the Italian care labour market? what are the connections between the largely informal and unskilled household care jobs and skilled social care occupations in professional care services? These are some of the key research questions that this thesis aims to tackle, mainly drawing on biographical interviews with a small sample of migrant care workers in the metropolitan area of Turin. A core argument here is that an agency-based approach, focused on the analysis of individual aspirations and every-day practices enacted by migrant care workers in Italy, would contribute to highlight important limitations in the theoretical frameworks on migrant care labour developed so far. Important policy implications will emerge from this explorative study on the life and occupational trajectories of migrant care workers in the Italian care regime.
THE EVOLUTION OF BINARY SYSTEMS IN GASEOUS ENVIRONMENTS
Creators: name: RAGUSA, ENRICO
Publisher: name: Universit� degli Studi di Milano

description: Systems where a binary, that is two gravitationally bound objects orbiting their centre of mass, interacts with the surrounding gas or dust are extremely common in the Universe and involve a wide variety of different astrophysical objects (star + star, black hole + black hole, star + planet, or planet + moon). Among them, protoplanetary systems and black hole binaries (BHBs) are currently capturing the attention of the scientific community. Despite their very different nature and EM appearance, both protoplanetary and BHB systems are characterized by the presence of a gaseous accretion disc surrounding the binary. As a consequence, the dynamics of these systems is very similar and can be described in one unique theoretical framework: the disc-satellite interaction theory. This project is meant to deepen our knowledge of the theory of circumbinary discs, approaching it in a multidisciplinary way from both the protoplanetary and the BHBs perspective.

Tidal break-up of binary stars at the Galactic center and its consequences

description: The tidal breakup of binary star systems by the supermassive black hole (SMBH) in the center of the galaxy has been suggested as the source of both the observed sample of hypervelocity stars (HVSs) in the halo of the Galaxy and the S-stars that remain in tight orbits around Sgr A*. Here, we use a post-Newtonian N-body code to study the dynamics of main-sequence binaries on highly elliptical bound orbits whose periapses lie close to the SMBH, determining the properties of ejected and bound stars as well as collision products. Unlike previous studies, we follow binaries that remain bound for several revolutions around the SMBH, finding that in the case of relatively large periapses and highly inclined binaries the Kozai resonance can lead to large periodic oscillations in the internal binary eccentricity and inclination. Collisions and mergers of the binary elements are found to increase significantly for multiple orbits around the SMBH, while HVSs are primarily produced during a binary's first passage. This process can lead to stellar coalescence and eventually serve as an important source of young stars at the galactic center.

Dynamical solutions in the 3-Form Field Background in the Nishino-Salam-Sezgin Model

description: We investigate the dynamical 3-form flux compactifications and their implications for cosmology in our brane world in the six-dimensional Nishino-Salam-Sezgin model, which is usually referred to as the Salam-Sezgin model. We take the background of the 3-form field acting on the internal space and timelike dimensions without the U(1) gauge field strength. The first class of solutions we discuss is the dynamical generalization of the static solutions obtained recently. In this class, we find that the time evolution is restricted only in the azimuthal dimension of the internal space and not in the ordinary three-dimensional one, which does not give a cosmological evolution. The second class of solutions is obtained by exchanging the roles of the radial coordinate and the time coordinate from the assumptions in the first class. At the center of the internal space, there is a conical singularity which may be interpreted as our 3-brane world, but it is difficult to realize a warped structure in the direction of the ordinary 3-space. Except for the oscillating solutions, a dynamical evolution leads to expanding or contracting ordinary 3-space, depending on the choice of time direction. Furthermore, in the expanding solutions, there are decelerating and accelerating ones: In the latter solution, the evolution is sustained for a finite proper time and the scale factor of the 3-space diverges.
