description: We compute the essential dimension of the functors Forms_{n,d} and Hypersurf_{n, d} of equivalence classes of homogeneous polynomials in n variables and hypersurfaces in P^{n-1}, respectively, over any base field k of characteristic 0. Here two polynomials (or hypersurfaces) over K are considered equivalent if they are related by a linear change of coordinates with coefficients in K. Our proof is based on a new Genericity Theorem for algebraic stacks, which is of independent interest. As another application of the Genericity Theorem, we prove a new result on the essential dimension of the stack of (not necessarily smooth) local complete intersection curves.

description: The Si(001) surface deoxidized by short annealing at T~925C in the ultrahigh vacuum molecular beam epitaxy chamber has been in situ investigated by high resolution scanning tunnelling microscopy (STM) and reflected high energy electron diffraction (RHEED). RHEED patterns corresponding to (2x1) and (4x4) structures were observed during sample treatment. The (4x4) reconstruction arose at T<600C after annealing. The reconstruction was observed to be reversible: the (4x4) structure turned into the (2x1) one at T>600C, the (4x4) structure appeared again at recurring cooling. The c(8x8) reconstruction was revealed by STM at room temperature on the same samples. A fraction of the surface area covered by the c(8x8) structure decreased as the sample cooling rate was reduced. The (2x1) structure was observed on the surface free of the c(8x8) one. The c(8x8) structure has been evidenced to manifest itself as the (4x4) one in the RHEED patterns. A model of the c(8x8) structure formation has been built on the basis of the STM data. Origin of the high-order structure on the Si(001) surface and its connection with the epinucleation phenomenon are discussed.

description: We have developed an all particle Fock-space relativistic coupled-cluster method for two-valence atomic systems. We then describe a scheme to employ the coupled-cluster wave function to calculate atomic properties. Based on these developments we calculate the excitation energies, magnetic hyperfine constants and electric dipole matrix elements of Sr, Ba and Yb. Further more, we calculate the electric quadrupole HFS constants and the electric dipole matrix elements of Sr$^+$, Ba$^+$ and Yb$^+$. For these we use the one-valence coupled-cluster wave functions obtained as an intermediate in the two-valence calculations. We also calculate the magnetic dipole hyperfine constants of Yb$^+$.

description: We investigate the analytical properties of the s-wave and p-wave holographic insulator/superconductor phase transitions at zero temperature. In the probe limit, we analytically calculate the critical chemical potentials at which the insulator/superconductor phase transition occurs. Those resulting analytical values perfectly match the previous numerical values. We also study the relations between the condensation values and the chemical potentials near the critical point. We find that the critical exponent for condensation operator is 1/2 for both models. The linear relations between the charge density and the chemical potential near the critical point are also deduced in this paper, which are qualitatively consistent with the previous numerical results.

description: We present the first detailed spatio-kinematical analysis and modelling of the planetary nebula Abell 41, which is known to contain the well-studied close-binary system MT Ser. This object represents an important test case in the study of the evolution of planetary nebulae with binary central stars as current evolutionary theories predict that the binary plane should be aligned perpendicular to the symmetry axis of the nebula. Deep narrowband imaging in the light of [NII], [OIII] and [SII], obtained using ACAM on the William Herschel Telescope, has been used to investigate the ionisation structure of Abell 41. Longslit observations of the H-alpha and [NII] emission were obtained using the Manchester Echelle Spectrometer on the 2.1-m San Pedro Mártir Telescope. These spectra, combined with the narrowband imagery, were used to develop a spatio-kinematical model of [NII] emission from Abell 41. The best fitting model reveals Abell 41 to have a waisted, bipolar structure with an expansion velocity of ~40km\s at the waist. The symmetry axis of the model nebula is within 5$\degr$ of perpendicular to the orbital plane of the central binary system. This provides strong evidence that the close-binary system, MT Ser, has directly affected the shaping of its nebula, Abell 41. Although the theoretical link between bipolar planetary nebulae and binary central stars is long established, this nebula is only the second to have this link, between nebular symmetry axis and binary plane, proved observationally.

description: tumor-Cancer stem cells (CSCs), Also known as initiating cells (tics), are elucidated as cells that can perpetuate themselves via auto restoration. these cells are highly resistant to current therapeutic approaches and are the main reason for cancer recurrence. Radiotherapy has made a lot of contributions to cancer treatment. However, despite continuous achievements, therapy resistance and tumor recurrence are still prevalent in most patients. This resistance might be partly related to the existence of cscs. In the present study, recent advances in the investigation of different biological properties of cscs, such as their origin, markers, characteristics, and targeting have been reviewed. We have also focused our discussion on radioresistance and adaptive responses of cscs and their related extrinsic and intrinsic influential factors. In summary, we suggest cscs as the prime therapeutic target for cancer treatment.

Novel, peptide-mediated neuroprotective strategies for Huntington's Disease
Creators: name: Girling, Kimberly Dayle
Publisher: name: University of British Columbia
Year: 2016

description: Huntington’s disease (HD) is an inherited neurodegenerative disease with progressive striatal loss. No treatments exist, though availability of predictive testing offers possibility for early intervention. Peptides represent an exciting way to interact with molecular signaling. My thesis investigates three potential early targets for preventative HD therapies: NMDAR-mediated PTEN nuclear translocation, caspase-6 activation, and peptide-mediated mutant huntingtin (mHTT) knockdown. Excitotoxicity via N-methyl-D-aspartate receptor (NMDAR) over-activation has a role in HD pathogenesis. We recently demonstrated that nuclear translocation of phosphatase and tensin homolog deleted on chromosome ten (PTEN) is a critical step in NMDAR-mediated excitotoxicity, and blocking PTEN nuclear translocation with peptide Tat-K13 prevents excitotoxic neuronal death. Given the role of NMDAR-mediated excitoxicity in HD, PTEN nuclear translocation may have a role in excitotoxic neuron death in HD. Here, PTEN nuclear translocation was associated with NMDAR-mediated death in cultured HD neurons. I also detected small increases in nuclear PTEN in HD transgenic mouse brains vs control. Interestingly, Tat-K13 effectively blocked PTEN translocation and prevented excitotoxicity in cortex/hippocampus, but not striatum, in vitro and in vivo, suggesting differential mechanisms of PTEN nuclear translocation. Caspase activation downstream of NMDARs may be critically involved in excitotoxicity. Caspase-6 (casp6) particularly, has roles in pathogenesis of HD and other conditions. Using NMDA-induced excitotoxicity in cultured neurons, I demonstrated early increase in caspase profiles via mRNA, protein and activity. Casp6 is elevated and activated first, followed by caspase-8 and caspase-3. Casp6 substrate huntingtin, and novel casp6 substrates STK3 and DAXX, are cleaved in similar temporal patterns post-NMDA, pointing to casp6 is an initiator caspase in NMDA-mediated apoptotic cascades and a potential therapeutic target. Many studies suggest that reducing mHTT protein may be an effective HD therapy. Our lab recently developed a technique for targeted protein degradation using peptides that signal proteins for lysosome- or proteasome-mediated degradation. Utilizing mHTT-binding domains paired with degradation sequences, I designed and tested mHTT-degradation peptides. In cultured neurons from HD transgenic mice, mHTT-degradation peptides led to robust mHTT knockdown, at least in part due to degradation. mHTT degradation peptides were ineffective in vivo, but pointed to potential for development of peptide-mediated mHTT-lowering therapies.

description: Reactions that involve the direct and sudden removal of a pair of like or unlike nucleons from a fast projectile beam by a light target nucleus are considered. Specifically, we study the three two-nucleon removal channels from $^{12}${C} that populate final states in the $^{10}${Be}, $^{10}${B} and $^{10}${C} reaction residues. The calculated two-nucleon removal cross sections and the residue momentum distributions are compared with available high energy data at 250, 1050 and 2010 MeV per nucleon, data that are inclusive with respect to the bound final-states of the residues. The measured $np$-removal cross sections only are significantly greater than the values calculated, suggesting that the reaction mechanism observes enhanced $np$ spatial correlations compared to those present in the shell-model wave functions.

description: The mobile machine industry is well-known for the development of complex mechatronic products. Additionally, low output volumes and a large number of product variants emphasize the requirement of a highly efficient product development process. In recent years, the virtualization of product design has turned out to be a key factor for reducing development time and costs. Especially for cross-company engineering, the development of virtual products by using a coupled simulation represents a promising approach. However, co-simulation has not been established as a common method on this market yet, there are still many challenges to take. In the project GUSMA, these challenges are accepted and an effective solution is developed.

description: We report the detection of a 0.6 M_J extrasolar planet by WASP-South, WASP-25b, transiting its solar-type host star every 3.76 days. A simultaneous analysis of the WASP, FTS and Euler photometry and CORALIE spectroscopy yields a planet of R_p = 1.22 R_J and M_p = 0.58 M_J around a slightly metal-poor solar-type host star, [Fe/H] = -0.05 \pm 0.10, of R_{\ast} = 0.92 R_{\odot} and M_{\ast} = 1.00 M_{\odot}. WASP-25b is found to have a density of ρ_p = 0.32 ρ_J, a low value for a sub-Jupiter mass planet. We investigate the relationship of planetary radius to planetary equilibrium temperature and host star metallicity for transiting exoplanets with a similar mass to WASP-25b, finding that these two parameters explain the radii of most low-mass planets well.

description: Silent ischemic infarcts have been reported to be the most frequent neurological abnormalities in sickle cell disease (SCD) in several studies worldwide. However, no previous studies investigated this neurological disorder in Iraqi SCD patients. To address this issue, a total of 52 patients with a median age of 20 years (range 10–46) and including 46.2% males were enrolled. Patients were clinically evaluated and their records were reviewed. They had full blood and reticulocyte counts, hemoglobin F estimation, serum lactic dehydrogenase and bilirubin assayed, as well as brain magnetic resonance imaging (MRI) to screen for silent cerebral infarcts. Six out of the 52 patients (11.5%) had silent cerebral infarcts, all of which were in the deep white matter, ranging from 6 to 10 mm in their largest diameters. There were no significant differences in age, sex, or sickle cell genotype between those with silent cerebral infarcts and those without it. Those with silent cerebral infarcts had lower median hemoglobin, higher reticulocytes and lower pain frequencies than those without it, yet again this was not significant. Follow up MRI in four out of the six silent infarct patients showed no additional lesions and no increase in size of the original ones after six to eight months. In conclusion, it appears that the frequency of silent cerebral infarcts in Iraqi SCD patients is lower than the bulk of the literature from other populations. Further studies to screen for genetic polymorphisms that may explain this lower rate may be informative.

description: Over the past decade the study of solar-like oscillations in red-giant stars has developed significantly. Not only the number of red-giant stars for which solar-like oscillations have been observed has increased, but the quality of these observations has improved as well. These steps forward were possible thanks to the development of instrumentation to measure radial velocity variations with a precision of the order of m/s, as well as the launch of dedicated space missions, which provide timeseries of data with unprecedented photometric precision. Many more exciting discoveries are to be expected in the (near) future. This article provides an overview of the development of the field over the last decade, discusses difficulties encountered and overcome in interpreting the observational data, and addresses some challenges and opportunities for further research.

We give the precise meaning of universality and discuss the standard universality classes (sine, Airy, Bessel) and their appearance in unitary, orthogonal, and symplectic ensembles. The Riemann-Hilbert problem for orthogonal polynomials is one possible tool to derive universality in unitary random matrix ensembles. An overview is presented of the Deift/Zhou steepest descent analysis of the Riemann-Hilbert problem in the one-cut regular case. Non-standard universality classes that arise at singular points in the spectrum are discussed at the end.

description: We studied the edge states and transverse electron focusing in the presence of spin-orbit interaction in a two dimensional electron gas. Assuming strong spin-orbit coupling we derived semiclassical quantization conditions to describe the dispersion of the edge states. Using the dispersion relation we then make predictions about certain properties of the focusing spectrum. Comparison of our analytical results with quantum mechanical transport calculations reveals that certain features of the focusing spectrum can be quite well understood in terms of the interference of the edge states while the explanation of other features seems to require a different approach.

Kurtág's Játékok as lessons in musical expression
Creators: name: Shi, Rui-Xuan
Publisher: name: University of British Columbia
Year: 2016

description: Teaching students to play the piano with more expression is one of the fundamental goals of piano pedagogy. The purpose of this study is to show how to help students develop careful and thoughtful articulation and interpretation, to gain experience performing contemporary piano works, as well as to improve their expression in the Classical and Romantic repertoire by having them learn selected pieces from Kurtág’s Játékok. Chapter 1 summarizes how musical “expression” has been defined by a number of philosophers, theorists, musicologists, and performers; it finds general agreement that four aspects of piano playing are especially important: tempo and flexible rhythm, dynamics, articulation, and sonority. Through analysis and discussion of many short pieces from Játékok Volume I – III, V – VII (Volumes IV and VIII are for piano duet and two pianos), Chapter 2 discusses how students can practice these aspects, learn a new music language through Kurtág’s notation, open their minds to accept new sound, and gain a complete knowledge of the music’s elaborate dynamic and expressive markings. The final chapter provides and discusses a progressive lesson plan, focusing on the major components that are demonstrated in Chapter 2. Kurtág’s Játékok is an excellent model for teaching, and it should be recognized and used as an important contribution to contemporary piano pedagogy.

description: We explore the synchronization behavior in interdependent systems, where the one-dimensional (1D) network (the intranetwork coupling strength $J_{\rm I}$) is ferromagnetically intercoupled (the strength $J$) to the Watts-Strogatz (WS) small-world network (the intranetwork coupling strength $J_{\rm II}$). In the absence of the internetwork coupling ($J = 0$), the former network is well known not to exhibit the synchronized phase at any finite coupling strength, whereas the latter displays the mean-field transition. Through an analytic approach based on the mean-field approximation, it is found that for the weakly coupled 1D network ($J_{\rm I} \ll 1$) the increase of $J$ suppresses synchrony, because the nonsynchronized 1D network becomes a heavier burden for the synchronization process of the WS network. As the coupling in the 1D network becomes stronger, it is revealed by the renormalization group (RG) argument that the synchronization is enhanced as $J_{\rm I}$ is increased, implying that the more enhanced partial synchronization in the 1D network makes the burden lighter. Extensive numerical simulations confirm these expected behaviors, while exhibiting a reentrant behavior in the intermediate range of $J_{\rm I}$. The nonmonotonic change of the critical value of $J_{\rm II}$ is also compared with the result from the numerical RG calculation.

description: While real Hamiltonian mechanics and Hermitian quantum mechanics can both be cast in the framework of complex canonical equations, their complex generalisations have hitherto been remained tangential. In this paper quaternionic and coquaternionic (split-signature analogue of quaternions) extensions of Hamiltonian mechanics are introduced, and are shown to offer a unifying framework for complexified classical and quantum mechanics. In particular, quantum theories characterised by complex Hamiltonians invariant under space-time reflection are shown to be equivalent to certain coquaternionic extensions of Hermitian quantum theories. One of the interesting consequences is that the space-time dimension of these systems is six, not four, on account of the structures of coquaternionic quantum mechanics.

description: The like-sign dimuon charge asymmetry of the $B$ meson, which was reported in the D$Ø$ Collaboration, is studied in the SU(5) SUSY GUT model with $S_4$ flavor symmetry. Additional CP violating effects from the squark sector are discussed in $B_s-\bar B_s$ mixing process. The predicted like-sign charge asymmetry is in the 2$σ$ range of the combined result of D$Ø$ and CDF measurements. Since the SUSY contributions in the quark sector affect to the lepton sector because of the SU(5) GUT relation, two predictions are given in the leptonic processes: (i) both ${\rm BR}(μ\to e γ)$ and the electron EDM are close to the present upper bound, (ii) the decay ratios of $τ$ decays, $τ\to μγ$ and $τ\to e γ$, are related to each other via the Cabibbo angle $λ_c$: ${\rm BR}(τ\to eγ)/{\rm BR}(τ\to μγ)\sime λ_c^2$. These are testable at future experiments.

Institutional humanism and the animalization of criminalized refugee youth in Canada
Creators: name: Francis, Jenny
Publisher: name: University of British Columbia
Year: 2016

description: Drawing on interviews with youth and youth professionals, this dissertation explores institutional humanism in the lives of the young people who took part in the study by focusing on the operationalization of humanist categories and exclusions in criminal justice, immigration, social welfare, and education policies. Examining the role of policy in the production of precarity, I argue that humanism is smuggled into institutional practice through racism, sexism, classism, ageism, and ableism, which, as expressions of being less than human, depend on the separation of the human (culture) from the non-human (nature) at the core of humanist thought. By creating conditions within which certain bodies are dehumanized and others are humanized, policies perform particular figurations of the human and sub/non-human; via these processes law and policy maintain race, class, gender, and species hierarchies. To make this argument, I analyse four performances that establish the separation of criminalized refugee youth from the human category: the erasure of personal histories, denial of human rights, production of disposability, and subjection to violence. These conditions are prompted by existing narratives that construct criminals, Muslims, Black people, youth, and refugees as less than human (closer to nature). Institutional policies and practices both reinforce and are sustained by discourses of humanity and animality that produce precarity as part of the “anthropological machine” that determines whose body and knowledge matters and who may be subjected to violence and denied rights and protections. These ontological and epistemological questions underscore the fragility of the human conceived as a separate and superior species. Focusing on species also offers a new way to consider how power and identity are inscribed in the lives of refugees and criminalized persons in Canada. Since addressing injustice at a deep level requires consideration of how human/nature dualisms underwrite violence, dispossession, and injustice, my aim is not the extension of liberal humanism to excluded Others, but a transformation of humanism.
Variational approximations to homoclinic snaking

description: We investigate the snaking of localised patterns, seen in numerous physical applications, using a variational approximation. This method naturally introduces the exponentially small terms responsible for the snaking structure, that are not accessible via standard multiple-scales asymptotic techniques. We obtain the symmetric snaking solutions and the asymmetric 'ladder' states, and also predict the stability of the localised states. The resulting approximate formulas for the width of the snaking region show good agreement with numerical results.

description: Η έννοια της καταναλωτικής συμπεριφοράς έχει πολυδιάστατο χαρακτήρα, με ένα σύνολο παραγόντων να επηρεάζουν την απόφαση του καταναλωτή για αγορά. Στις υπηρεσίες, λόγω της ιδιαίτερης φύσης τους, τόσο το σύστημα εξυπηρέτησης μιας εταιρίας παροχής υπηρεσιών όσο και τα επίπεδα καινοτομικότητας της είναι βασικοί παράγοντες καθορισμού της ποιότητας της υπηρεσίας που προσφέρει και εν τέλει την διαφοροποιούν από τον ανταγωνισμό. Ειδικά για τον κλάδο αυτοκινήτων, η διασφάλιση της ποιότητας και η βέλτιστη ανταπόκριση έχουν σημαντική θετική σχέση με την ικανοποίηση των πελατών, επιδρώντας άμεσα και θετικά την αφοσίωση τους στο συνεργείο. Σκοπός της παρούσας έρευνας ήταν η μελέτη της συμπεριφοράς που έχουν οι κάτοχοι οχημάτων σε σχέση με τη διαδικασία της συντήρησης τους. Η έρευνα ήταν ποσοτική με εργαλείο το ερωτηματολόγιο και έγινε σε δείγμα 207 οδηγών οχημάτων FORD που απευθύνθηκαν στα εξουσιοδοτημένα κέντρα τεχνικής υποστήριξης της ανωτέρω εταιρίας στο Ρέντη και στην Αργυρούπολη. Η έρευνα πραγματοποιήθηκε δια ζώσης στα δύο εξουσιοδοτημένα κέντρα τεχνικής υποστήριξης της εταιρίας FORD στις αρχές του 2019 (Ιανουάριος - Φεβρουάριος). Τα αποτελέσματα έδειξαν ότι η ηλικία, το μορφωτικό επίπεδο, το φύλο, το έτος αγοράς και η περιοχή του συνεργείου δε παίζουν κανένα ρόλο στην πιθανότητα σύστασης και χρήσης το συνεργείου. Ακόμα η ικανοποίηση από την εξυπηρέτηση και την ενημέρωση για το κόστος καθώς και η αξιολόγηση του χώρου επίσης δεν επηρεάζονται από τους παράγοντες που αναφέρθηκαν. Σε αυτά τα χαρακτηριστικά φάνηκε από την ανάλυση ότι οι κάτοχοι των οχημάτων είναι ικανοποιημένοι σε ότι αφορά την εξυπηρέτηση του τεχνικού συμβούλου, το κόστος, την εμφάνιση και την καθαριότητα του χώρου, με εμφανή την θετική τους στάση για επανεπίσκεψη στο συνεργείο στο μέλλον.

description: Este proyecto tiene como objeto estudiar lo masculino-paterno en la novela Los infieles Vol. 1. Acto de pudor, del escritor cartagenero Efraim Medina Reyes, con el propósito de dar cuenta de sus representaciones in/móviles. Parto de la hipótesis de que lo masculinopaterno en la novela es construido como respuesta a las discursividades e imaginarios tradicionales que impiden el afianzamiento de vínculos y obligan al silencio. Para su estudio, identifico, en primer lugar, los discursos socioestéticos –hegemónicos y contrahegemónicos– sobre lo masculino-paterno que posibilitan Los infieles Vol. 1; determino, en segundo lugar, las representaciones de lo masculino-paterno a partir de una dialéctica de lo in/móvil; y, por último, evalúo los alcances y paradojas de esta in/movilidad.
Localized mode interactions in 0-pi Josephson junctions

description: A long Josephson junction containing regions with a phase shift of pi is considered. By exploiting the defect modes due to the discontinuities present in the system, it is shown that Josephson junctions with phase-shift can be an ideal setting for studying localized mode interactions. A phase-shift configuration acting as a double-well potential is considered and shown to admit mode tunnelings between the wells. When the phase-shift configuration is periodic, it is shown that localized excitations forming bright and dark solitons can be created. Multi-mode approximations are derived confirming the numerical results.

description: Sulfur is important: the site of its formation is uncertain, and at very low metallicity the trend of [S/Fe] against [Fe/H] is controversial. Below [Fe/H]=-2.0, [S/Fe] remains constant or it decreases with [Fe/H], depending on the author and the multiplet used in the analysis. Moreover, although sulfur is not significantly bound in dust grains in the ISM, it seems to behave differently in DLAs and in old metal-poor stars. We aim to determine precise S abundance in a sample of extremely metal-poor stars taking into account NLTE and 3D effects. NLTE profiles of the lines of the multiplet 1 of SI have been computed using a new model atom for S. We find sulfur in EMP stars to behave like the other alpha-elements, with [S/Fe] remaining approximately constant for [Fe/H]
