description: We present a study on the origin of the metallicity evolution of the intra-cluster medium (ICM) by applying a semi-analytic model of galaxy formation to N-body/SPH (smoothed particle hydrodynamic) non-radiative numerical simulations of clusters of galaxies. The semi-analytic model includes gas cooling, star formation, supernovae feedback and metal enrichment, and is linked to the diffuse gas of the underlying simulations so that the chemical properties of gas particles are dynamically and consistently generated from stars in the galaxies. This hybrid model let us have information on the spatial distribution of metals in the ICM. The results obtained for a set of clusters with virial masses of ~1.5*10^15 h^{-1} M_sun contribute to the theoretical interpretation of recent observational X-ray data, which indicate a decrease of the average iron content of the intra-cluster gas with increasing redshift. We find that this evolution arises mainly as a result of a progressive increase of the iron abundance within ~0.15 R_vir. The clusters have been considerably enriched by z~1 with very low contribution from recent star formation. Low entropy gas that has been enriched at high redshift sinks to the cluster centre contributing to the evolution of the metallicity profiles.

description: We conducted a joint experimental-theoretical investigation of the high-pressure chemistry of europium polyhydrides at pressures of 86-130 GPa. We discovered several novel magnetic Eu superhydrides stabilized by anharmonic effects: cubic $EuH_{9}$, hexagonal $EuH_{9}$, and an unexpected cubic (Pm-3n) clathrate phase, $Eu_{8}H_{46}$. Monte Carlo simulations indicate that cubic $EuH_{9}$ has antiferromagnetic ordering with T(Neel) up to 24 K, whereas hexagonal $EuH_{9}$ and Pm-3n-$Eu_{8}H_{46}$ possess ferromagnetic ordering with T(Curie) = 137 and 336 K, respectively. The electron-phonon interaction is weak in all studied europium hydrides, and their magnetic ordering excludes s-wave superconductivity, except, perhaps, for distorted pseudohexagonal $EuH_{9}$. The equations of state predicted within the DFT+U approach (the Hubbard corrections were found within linear response theory) are in close agreement with the experimental data. This work shows the great influence of the atomic radius on symmetry-breaking distortions of the crystal structures of superhydrides and on their thermodynamic stability.

description: The francium atom is considered as a prospective candidate system to search for the T,P-violating electron electric dipole moment [T. Aoki et al Quantum Sci. Technol. 6, 044008 (2021)]. We demonstrate that the same experiment can be used for axionlike particles (ALP) search. For this, we calculate electronic structure constants of ALP-mediated interaction for a wide range of ALP masses. Using the recently updated constraints on the ALP-electron and ALP-nucleon coupling constants, we show that the contribution of considered interactions corresponding to these constraints can give significant contribution to atomic electric dipole moment. Therefore, obtainment of stronger restrictions for ALP characteristics in the francium atom electric dipole moment experiment is possible.

description: We report on a calculation of the `mixed' strong and (purely) weak corrections through the order $α_{\mathrm{S}}^2α_{\mathrm{W}}$ to parton-parton processes in all possible channels at hadron colliders entering the single jet inclusive cross section. At both Tevatron and LHC, such effects are always negligible (below permille level) in the total integrated cross section whilst they become sizable in differential rates. Specifically, if such corrections are defined with respect to the full leading-order result of ${\cal O}(α_{\mathrm{S}}^2 +α_{\mathrm{S}}α_{\mathrm{EW}}+α_{\mathrm{EW}}^2)$, we find that, at the FNAL accelerator, they can reach the -5% benchmark in the jet transverse energy (at the kinematical limit of the machine, rendering their detection quite difficult). At the CERN collider, in the same observable, they exceed the -10% level already at 1 TeV and can reach -40% at 4 TeV, kinematic regions where such corrections will be comfortably observable for standard luminosity. In addition, such corrections are somewhat sensitive to the factorisation/renormalisation scale choice.

description: Using high-resolution spectropolarimetric data recorded with the Swedish 1 m Solar Telescope, we have identified several instances of granular lanes traveling into granules. These are believed to be the observational signature of underlying tubes of vortical flow with their axis oriented parallel to the solar surface. Associated with these horizontal vortex tubes, we detect in some cases a significant signal in linear polarization, located at the trailing dark edge of the granular lane. The linear polarization appears at a later stage of the granular lane development, and is flanked by patches of circular polarization. Stokes inversions show that the elongated patch of linear polarization signal arises from the horizontal magnetic field aligned with the granular lane. We analyze snapshots of a magnetohydrodynamic numerical simulation and find cases in which the horizontal vortex tube of the granular lane redistributes and transports the magnetic field to the solar surface causing a polarimetric signature similar to what is observed. We thus witness a mechanism capable of transporting magnetic flux to the solar surface within granules. This mechanism is probably an important component of the small-scale dynamo supposedly acting at the solar surface and generating the quiet-Sun magnetic field.

description: We present Keck optical spectra of SN 2002cx, the most peculiar known Type Ia supernova (SN Ia), taken 227 and 277 days past maximum light. Astonishingly, the spectra are not dominated by the forbidden emission lines of iron that are a hallmark of thermonuclear supernovae in the nebular phase. Instead, we identify numerous P-Cygni profiles of Fe II at very low expansion velocities of about 700 km/s, which are without precedent in SNe Ia. We also report the tentative identification of low-velocity O I in these spectra, suggesting the presence of unburned material near the center of the exploding white dwarf. SN 2002cx is the prototype of a new subclass of SNe Ia, with spectral characteristics that may be consistent with recent pure deflagration models of Chandrasekhar-mass thermonuclear supernovae. These are distinct from the majority of SNe Ia, for which an alternative explosion mechanism, such as a delayed detonation, may be required.

description: I musei d'impresa avvicinano storia, tecnologia e innovazione al fine di narrare l'impatto delle imprese e delle industrie sulla società, sulla cultura e l'economia di un territorio. A differenza dei musei tradizionali, il valore dei musei d'impresa non risiede solo nei beni esposti, ma nel messaggio e nell'esperienza che trasmettono. Difatti, ogni museo rappresenta un caso unico, dato che la storia imprenditoriale che raccontano è esclusiva e per questa ragione essi svolgono molteplici ruoli, dalla celebrazione di eventi legati alle aziende e famiglie, alla fornitura di servizi di comunicazione e formazione imprenditoriale, fino a contribuire alla promozione della responsabilità sociale e culturale delle imprese. I musei d'impresa sono anche motori di attività di ricerca, conservazione e trasmissione del patrimonio materiale e immateriale delle aziende. Inoltre, contribuiscono alla valorizzazione dell'identità dell'azienda e dei legami impresa-territorio-stakeholder, trasformando il passato industriale in risorse culturali, identitarie e formative per la comunità locale e il pubblico più vasto. Tuttavia, tali musei affrontano sfide finanziarie, gestionali e tecnologiche, che richiedono approcci innovativi per la loro sostenibilità a lungo termine. Per analizzare questi aspetti, attraverso l'analisi di alcuni casi studio significativi, è stata condotta una indagine, tramite interviste, rivolta ad aziende che hanno fondato un museo d'impresa, con l'obiettivo di comprendere la storia e i fattori che hanno spinto alla creazione del museo, oltre a valutare i costi necessari per la sua istituzione e gestione nel tempo. Un'attenzione particolare è stata dedicata all'indagine dei valori che ciascun museo analizzato intende trasmettere e alle attività svolte al suo interno, al fine di valutare il ruolo che il museo riveste nel processo di valorizzazione del patrimonio industriale e dello sviluppo territoriale. Infine, sono state esplorate le prospettive future del museo, tenendo conto delle attuali sfide e delle opportunità che caratterizzano il settore culturale. Le informazioni raccolte hanno permesso di elaborare una visione completa e dettagliata del ruolo che i musei d'impresa sono chiamati a svolgere nell'ambito della valorizzazione della cultura e dei valori aziendali, nonché nello sviluppo socioculturale del territorio in cui operano.

description: Free nodal fermionic excitations are simple but interesting examples of fermionic quantum criticality in which the dynamic critical exponent $z=1$, and the quasiparticles are well defined. They arise in a number of physical contexts. We derive the scaling form of the diamagnetic susceptibility, $χ$, at finite temperatures and for finite chemical potential. From measurements in graphene, or in $\mathrm{Bi_{1-x}Sb_{x}}$ ($x=0.04$), one may be able to infer the striking Landau diamagnetic susceptibility of the system at the quantum critical point. Although the quasiparticles in the mean field description of the proposed $d$-density wave (DDW) condensate in high temperature superconductors is another example of nodal quasiparticles, the crossover from the high temperature behavior to the quantum critical behavior takes place at a far lower temperature due to the reduction of the velocity scale from the fermi velocity $v_{F}$ in graphene to $\sqrt{v_{F}v_{\mathrm{DDW}}}$, where $v_{\mathrm{DDW}}$ is the velocity in the direction orthogonal to the nodal direction at the Fermi point of the spectra of the DDW condensate.

The post-buckling of this layer is investigated experimentally; the wavelengths and amplitudes of the resulting modes are measured. A simplified model with a self-avoiding rod on a Winkler foundation is in semi-quantitative agreement with experiments and reproduces the observed cusp-like folds.

description: We report on direct numerical simulation of quasi-one-dimensional bidirectional capillary-wave turbulence. Although nontrivial three-wave and four-wave resonant interactions are absent in this peculiar geometry, we show that an energy transfer between scales still occurs concentrated around the linear dispersion relation that is broadened by nonlinearity. The wave spectrum displays a clear wave number power-law scaling that is found to be in good agreement with the dimensionally prediction for capillary-wave turbulence involving four-wave interactions. The carried out high-order correlation analysis (bicoherence and tricoherence) confirms quantitatively the dominant role of four-wave quasi-resonant interactions. The Kolmogorov-Zakharov spectrum constant is also estimated numerically. We interpret our results as the first numerical observation of anisotropic capillary-wave turbulence in which four-wave interactions play a dominant role

description: We show that Anderson localization in quasi-one dimensional conductors with ballistic electron dynamics, such as an array of ballistic chaotic cavities connected via ballistic contacts, can be understood in terms of classical electron trajectories only. At large length scales, an exponential proliferation of trajectories of nearly identical classical action generates an abundance of interference terms, which eventually leads to a suppression of transport coefficients. We quantitatively describe this mechanism in two different ways: the explicit description of transition probabilities in terms of interfering trajectories, and an hierarchical integration over fluctuations in the classical phase space of the array cavities.

description: The ability of phase-change materials to reversibly and rapidly switch between two stable phases has driven their use in a number of applications such as data storage and optical modulators. Incorporating such materials into metasurfaces enables new approaches to the control of optical fields. In this article we present the design of novel switchable metasurfaces that enable the control of the nonclassical two-photon quantum interference. These structures require no static power consumption, operate at room temperature, and have high switching speed. For the first adaptive metasurface presented in this article, tunable nonclassical two-photon interference from -97.7% (anti-coalescence) to 75.48% (coalescence) is predicted. For the second adaptive geometry, the quantum interference switches from -59.42% (anti-coalescence) to 86.09% (coalescence) upon a thermally driven crystallographic phase transition. The development of compact and rapidly controllable quantum devices is opening up promising paths to brand-new quantum applications as well as the possibility of improving free space quantum logic gates, linear-optics bell experiments, and quantum phase estimation systems.

description: Characterizing the quantum complexity of local random quantum circuits is a very deep problem with implications to the seemingly disparate fields of quantum information theory, quantum many-body physics and high energy physics. While our theoretical understanding of these systems has progressed in recent years, numerical approaches for studying these models remains severely limited. In this paper, we discuss a special class of numerically tractable quantum circuits, known as quantum automaton circuits, which may be particularly well suited for this task. These are circuits which preserve the computational basis, yet can produce highly entangled output wave functions. Using ideas from quantum complexity theory, especially those concerning unitary designs, we argue that automaton wave functions have high quantum state complexity. We look at a wide variety of metrics, including measurements of the output bit-string distribution and characterization of the generalized entanglement properties of the quantum state, and find that automaton wave functions closely approximate the behavior of fully Haar random states. In addition to this, we identify the generalized out-of-time ordered 2k-point correlation functions as a particularly useful probe of complexity in automaton circuits. Using these correlators, we are able to numerically study the growth of complexity well beyond the scrambling time for very large systems. As a result, we are able to present evidence of a linear growth of design complexity in local quantum circuits, consistent with conjectures from quantum information theory.

Ligand binding studies on Ly-49
Creators: name: Mahon, Gwendolyn Maria
Publisher: name: University of British Columbia
Year: 2009

description: Ly-49 is a highly polymorphic family of molecules expressed almost exclusively on murine natural killer cells ( NK cells). Ly-49 family members appear to play an important role in the recognition of tumor targets by N K cells and act as putative inhibitory receptors on NK cells for MHC class I on target cells. Ly-49 is a type-II transmembrane protein consisting of two non-covalently associated chains, a short amino terminus cytoplasmic tail, a transmembrane domain, and a carboxy terminus carbohydrate recognition domain which takes up approximately 60% of the extracellular domain. The objective of this thesis was to determine the region of Ly-49 responsible for ligand binding specificity. The approach was to generate a number of chimeric constructs in which different regions of. Ly-49 were exchanged between two members of the Ly-49 family, Ly-49 A and Ly-49C. These two members were chosen because they have distinct binding specificities and because of the availability of specific monoclonal antibodies which have been shown to inhibit binding of these two members to their H-2 ligands. The chimeric constructs were placed in a suitable expression vector and expressed on the surface of COS-1 cells using a transient expression system. Ligand binding specificity was determined using a cell adhesion assay which involved the binding of non-adherent cell lines of different haplotypes to the transfected COS-1 cells. Antibody binding was determined by staining cells with fluorescently labeled antibody followed by fluorescence activated cell scanning analysis. Although all of the Ly-49 antibodies bind completely within the carbohydrate recognition domain, this domain alone is unable to determine ligand binding specificity. Further carboxy terminal exchanges define a 19 amino acid region outside the CRD that is necessary, but by itself not sufficient to determine ligand binding. In conclusion, the region responsible for determining binding specificity is a combination of the CRD and the region defined in this study.

description: This work is intended as a contribution to a wavelet-based adaptive estimator of the memory parameter in the classical semi-parametric framework for Gaussian stationary processes. In particular we introduce and develop the choice of a data-driven optimal bandwidth. Moreover, we establish a central limit theorem for the estimator of the memory parameter with the minimax rate of convergence (up to a logarithm factor). The quality of the estimators are attested by simulations.

description: We present a new and efficient method to obtain a Gamow shell-model basis and matrix elements generated by realistic nucleon-nucleon interactions. We derive a self-consistent Hartree-Fock potential from the renormalized N3LO interaction model. The corresponding Gamow one-body eigenstates are generated in a plane wave basis in order to build a Gamow shell-model set of basis states for the closed shell nuclei 4He and 16O. We address also the problem of representing a realistic nucleon-nucleon interaction in a two-particle Berggren basis in the laboratory frame. To achieve this, an expansion of matrix elements of the residual nucleon-nucleon interaction in a finite set of harmonic oscillator wave functions is used. We show that all loosely bound and narrow resonant states converge surprisingly fast. Even broad resonances in these two-particle valence systems converge within a reasonable number of harmonic oscillator functions. Examples of 6He and 18O Gamow shell-model calculations using 4He and 16}O as closed shell cores are presented. This procedure allows Gamow shell-model calculations to be performed with all realistic nucleon-nucleon interactions and with either momentum or position space representations for the Gamow basis. The possibility to remove the center of mass spuriosity of Gamow shell-model nuclear states with this method is also discussed. Perspectives for nuclear structure calculations of dripline nuclei are outlined.

Mixing and lifetimes of $b$-hadrons

Year: 2008

description: We review the status of mixing and lifetimes of $b$-hadrons. We will show that $ΔΓ/ ΔM$, $a_{sl}$ and $ϕ$ are better suited to search for new physics effects than $ΔM$ alone, because of our poor knowledge of the decay constants. The theoretical precision in the determination of $Γ_{12} / M_{12}$ - which contains all information on $ΔΓ/ ΔM$, $a_{sl}$ and $ϕ$ - can be tested directly by investigating the lifetimes of $b$-hadrons, because both quantities rely on the same theoretical footing. In particular we will also present a numerical estimate for the lifetime of the $Ξ_b$-baryon.

description: We explore the non-linear dynamics of two parallel periodically patterned metal surfaces that are coupled by the zero-point fluctuations of the electromagnetic field between them. The resulting Casimir force generates for asymmetric patterns with a time-periodically driven surface-to-surface distance a ratchet effect, allowing for directed lateral motion of the surfaces in sizeable parameter ranges. It is crucial to take into account inertia effects and hence chaotic dynamics which are described by Langevin dynamics. Multiple velocity reversals occur as a function of driving, mean surface distance, and effective damping. These transport properties are shown to be stable against weak ambient noise.

Despite remaining amorphous status, with increasing the annealing temperature, the defect level within amorphous BaSnO3 thin films could be suppressed.

description: We report a study of disordered electron systems with spin-orbit coupling on a cylinder using methods of random matrix ensembles. With a threading flux turned on, the single particle levels will generally avoid, rather than cross, each other. Our numerical study of the level-avoiding gaps in the disordered Rashba model demonstrates that the normalized gap distribution is of a universal form, independent of the random strength and the system size. For small gaps it exhibits a linear behavior, while for large gaps it decays exponentially. A framework based on matrix mechanical models is suggested, and is verified to reproduce the universal linear behavior at small gaps. Thus we propose to use the distribution of the spectral-flow gaps associated with flux insertion as a new way to characterize 2d random systems with spin-orbit coupling. The relevance and qualitative implications for spin (Hall) transport are also addressed.

The impact of different level of DER/EV penetration on the voltages across the network is typically quantified through voltage sensitivity analyses. Existing methods of voltage sensitivity analysis are computationally expensive and prior efforts to develop analytical approximation lacks generality and have not been effectively validated. The objective of this work is to provide a new analytical method of voltage sensitivity analysis that has low computational cost and also allows for stochastic analysis of voltage change. This paper first derives an analytical approximation of change in voltage at a particular bus due to change in power consumption at other bus in a radial three phase unbalanced power distribution system. Then, the proposed method is shown to be valid for different load configurations, which demonstrates its generality. The results from our analytical approach is validated via classical load flow simulation of the test system based on IEEE 37 bus network. The proposed method is shown to have good accuracy, and computation complexity is of order O(1), compared to O(n3) in classical sensitivity analysis approaches.

description: This article introduces a multiple classifier method to improve the performance of concatenate-designed neural networks, such as ResNet and DenseNet, with the purpose to alleviate the pressure on the final classifier. We give the design of the classifiers, which collects the features produced between the network sets, and present the constituent layers and the activation function for the classifiers, to calculate the classification score of each classifier. We use the L2 normalization method to obtain the classifier score instead of the Softmax normalization. We also determine the conditions that can enhance convergence. As a result, the proposed classifiers are able to improve the accuracy in the experimental cases significantly, and show that the method not only has better performance than the original models, but also produces faster convergence. Moreover, our classifiers are general and can be applied to all classification related concatenate-designed network models.

The construction of buildings and histories: Hudson’s Bay Company department stores, 1912-26
Creators: name: Monteyne, David P.
Publisher: name: University of British Columbia
Year: 2009

description: Between 1913 and 1926, the aged British commercial institution, the Hudson's Bay Company (HBC), built four monumental department stores across Western Canada in Calgary, Vancouver, Victoria, and Winnipeg. In this thesis extensive archival research on the buildings and the HBC's architectural policies is analyzed within the contexts of Canadian social history, and of Company business history. The HBC was making new advances into the department store field, and the stores were clad in a standardized style intended to create a particular image of the Company in contrast to its competitors. Popular in Britain at the time, this Edwardian Classicism emphasized the HBC's history as the official representative of the British Empire across the hinterlands, a history largely defunct by the turn of the century. The opulent style also helped to establish the stores as key cultural institutions and as palaces of consumption. After World War One the HBC also began to stress its specific historical role in the Canadian fur trade and the settlemehtof the nation, through the use of various other architectural features such as the display windows, art galleries and museums set up inside the new stores, and by the historical sites of Company buildings. The competition between historical themes -British Imperial and Canadian frontierist- evidenced in the HBC department stores were tied to social factors. Demographic changes and nationalist sentiment after WWI forced the HBC to recognize Canada's particular pluralist society, and to mediate its image as a purely British organization. Many staff members and customers had no ties to the Company or the Empire, so the HBC invented a tradition that the public could relate to and participate in. The codification of a representational strategy was complicated by the differing agendas of the Company's London Board and its Canadian management. The study of architectural issues such as urban context, style, and building use establishes how the modern HBC employed history through modes of representation in the built environment, to justify its claims to the loyalty of a diverse population of workers and customers.

Strongly renormalized quasi-two-dimensional electron gas in a heterostructure with correlation effects

description: We present aspects of strong electron correlation in a model of a BI/M/BI heterostructure where BI is a band insulator and M can be tuned from a metal to a Mott insulator by varying the on-site repulsion. An effective one-dimensional Schroedinger equation for the low-energy part is derived in the framework of the Kotliar-Ruckenstein slave-boson mean-field theory and solved self-consistently for a wide range of the on-site interaction strength and of the width of the sandwiched material M. In the strongly interacting limit coherent quasiparticles responsible for metallic behavior are confined to a relatively narrow region near the interfaces where they form a quasi-two-dimensional electron gas. Due to the lack of spatial homogeneity these quasiparticles intrinsically obtain a nontrivial dependence on the transverse momentum which for example enters the low-energy behavior of the optical conductivity.

description: We employ transformation optics to optimize the generic nonlinear wave interaction of second-harmonic generation from a pair of touching metallic wires. We demonstrate a 10 orders of magnitude increase in the second-harmonic scattering cross-section by increasing the background permittivity and a 5 orders of magnitude increase in efficiency with respect to a single wire. These results have clear implications for the design of nanostructured metallic frequency-conversion devices. Finally, we exploit our analytic solution of a non-trivial nanophotonic geometry as a platform for performing a critical comparison of the strengths, weaknesses and validity of other prevailing theoretical approaches previously employed for nonlinear wave interactions at the nanoscale.
A large population of metal-rich, compact, intergalactic C IV absorbers - Evidence for poor small-scale metal mixing

description: We carried out a survey for high-metallicity C IV absorbers at redshift z ~ 2.3 in the spectra of 9 high-quality quasar spectra. Using a novel analysis technique, based on detections of C IV lines and automatically determined upper limits on the column densities of H I, C III, N V, and O VI, we find a large (dN/dz > 7) population of photo-ionized, compact (R ~ 10^2 pc), metal-rich (Z >~ Z_solar) C IV clouds with moderate densities (n_H ~ 10^{-3.5} cm^{-3}), properties that we show are robust with respect to uncertainties in the ionization model. In particular, local sources of ionizing radiation, overabundance of oxygen, departures from ionization equilibrium, and collisional ionization would all imply more compact clouds. The clouds are too small to be self-gravitating and pressure confinement is only consistent under special conditions. We argue that the clouds are, in any case, likely to be short-lived and we demonstrate that this implies that the clouds could easily have been responsible for the transport of all metals that end up in the intergalactic medium (IGM). When the clouds reach pressure equilibrium with the general, photo-ionized IGM, the metals will still be concentrated in small high-metallicity patches, but they will look like ordinary, low-metallicity absorbers. We conclude that intergalactic metals are poorly mixed on small scales and that nearly all of the IGM, and thus the universe, may therefore be of primordial composition.

description: We present and analyze two algorithms for computing the Hilbert class polynomial $H_D$ . The first is a p-adic lifting algorithm for inert primes p in the order of discriminant D < 0. The second is an improved Chinese remainder algorithm which uses the class group action on CM-curves over finite fields. Our run time analysis gives tighter bounds for the complexity of all known algorithms for computing $H_D$, and we show that all methods have comparable run times.

description: Vortex dynamics in a restricted geometry is considered for a magnetic system consisting of ferromagnetic cylindrical dots. To describe the vortex dynamic susceptibility and relaxation the equation of motion for the vortex center position is applied. The dependencies of the vortex dynamic susceptibility and resonance linewidth on geometrical parameters are calculated. A new method of extracting damping parameter from the vortex low-frequency resonance peaks is proposed and applied for interpretation of resonance data on FeNi circular dots.
