description: The collision of winds from massive stars in binaries results in the formation of a double-shock structure with observed signatures from radio to X-rays. We study the structure and stability of the colliding wind region as it turns into a spiral due to orbital motion. We focus on adiabatic winds, where mixing between the two winds is expected to be restricted to the Kelvin-Helmholtz instability (KHI). Mixing of the Wolf-Rayet wind with hydrogen-rich material is important for dust formation in pinwheel nebulae such as WR 104, where the spiral structure has been resolved in infrared. We use the hydrodynamical code RAMSES with an adaptive grid. A wide range of binary systems with different wind velocities and mass loss rates are studied with 2D simulations. A specific 3D simulation is performed to model WR 104. Orbital motion leads to the formation of two distinct spiral arms where the KHI develops differently. We find that the spiral structure is destroyed when there is a large velocity gradient between the winds, unless the collimated wind is much faster. We argue that the KHI plays a major role in maintaining or not the structure. We discuss the consequences for various colliding wind binaries. When stable, there is no straightforward relationship between the spatial step of the spiral, the wind velocities, and the orbital period. Our 3D simulation of WR 104 indicates that the colder, well-mixed trailing arm has more favourable conditions for dust formation than the leading arm. The single-arm infrared spiral follows more closely the mixing map than the density map, suggesting the dust-to-gas ratio may vary between the leading and trailing density spirals. However, the density is much lower than what dust formation models require. Including radiative cooling would lead to higher densities, and also to thin shell instabilities whose impact on the large structure remains unknown.

description: Gaussian quantum discord is a measure of quantum correlations in Gaussian systems. Using Gaussian discord we quantify the quantum correlations of a bipartite entangled state and a separable two-mode mixture of coherent states. We experimentally analyze the effect of noise addition and dissipation on Gaussian discord and show that the former noise degrades the discord while the latter noise for some states leads to an increase of the discord. In particular, we experimentally demonstrate the near-death of discord by noisy evolution and its revival through dissipation.

description: Following anterior cruciate ligament rupture (ACLX) in the knee, rapid periarticular bone loss often occurs prior to the subchondral sclerosis of end-stage osteoarthritis (OA). In a model of knee osteoarthritis, changes were examined in subchondral periarticular bone mineral and microarchitecture (IlCT) and in the femoral insertion of the medial collateral ligament (MCL). Also assessed were whether antiresorptive therapy with a bisphosphonate (BP [risedronate]) altered those bone adaptations in the subchondral plate, at the MCL-insertion, and after ACL-reconstruction, and if BP intervention influenced ligament-complex biomechanics and OA progression. Finally, molecular expression of a bone cytokine (osteoprotegerin [OPG]) in periarticular tissues undergoing remodeling and the influence of BP therapy upon the regulation of that gene were investigated. Early alterations of periarticular bone mineral after ACLX included significant loss in subchondral trabecular bone and in bone at the MCL-insertion. Compared to normal controls, MCL-complex laxity and bone loss at the MCL-insertion were significantly greater in the ACLX cohort at 6 wk and had increased further by 14 wk after ACLX. If ACLX animals were dosed daily with risedronate bisphosphonate for 6 wk, however, MCL-complex laxity was significantly improved, and the loss of MCL insertional bone was significantly less and not significantly different from normal control animals. When animals were dosed up to 24 wk after ACLX with BP, however, the progression of OA was not altered. The transient restabilization of the joint by ACL-reconstruction, in conjunction with BP-dosing, did little to block the progression of OA. The expression of OPG was altered following loss of the ACL, and the BP risedronate countered that effect-resulting in the return of OPG expression in bone and fibrocartilaginous tissues. Such adaptive responses in connective tissues after ACLX may have been necessary for the maintenance and repair of the injured structures. The results suggested a potential therapeutic role for antiresorptive bisphosphonate therapy to inhibit adaptive remodeling early following non-fracture joint trauma. Long-term administration of the BP, however, did not appear to be beneficial, and the ultimate effect of the short-term use of the BP on osteoarthritis progression remains to be determined.

description: We analyze the quantum statistical treatment of bound states in Hydrogen considered as a system of electrons and protons. Within this physical picture we calculate isotherms of pressure for Hydrogen in a broad density region and compare to some results from the chemical picture. First we resume in detail the two transitions along isotherms : (i) the formation of bound states occurring by increasing the density from low to moderate values, (ii) the destruction of bound states in the high density region, modelled here by Pauli-Fock effects. Avoiding chemical models we will show, why bound states according to a discrete part of the spectra occur only in a valley in the T-p plane. First we study virial expansions in the canonical ensemble and then in the grand canonical ensemble. We show that in fugacity representations the population of bound states saturates at higher density and that a combination of both representations provides quickly converging equations of state. In the case of degenerate systems we calculated first the density-dependent energy levels, and find the pressure in Hartree-Fock-Wigner approximation showing the prominent role of Pauli blocking and Fock effects in the selfenergy.

description: Bibliography: p. 180-183
description: Microscopie traffic simulation models have become widely used tools in transportation engineering because they are able to reproduce queues, shock waves, weaving areas, merging zones, gap acceptance behaviour, fixed and actuated traffic signals, and many other traffic characteristics observed in real life. Testing road designs and traffic control systems, analysis of intelligent transportation systems, evaluating traffic management schemes, and calibrating adaptive control systems are important applications of microscopic models that require a well calibrated model to produce satisfactory results. The principal objective of this research is to document and analyze the sensitivity and global network impacts of parameters used to calibrate PARAMICS, which is one of the most popular and powerful microscopic traffic models. Based on this analysis, recommendations have been made, which
Beyond the Dailey-Townes model: chemical information from the electric field gradient

Publisher: name: Zenodo
Year: 2023
Subjects: Electric field gradient, Nuclear quadrupole moment, Relativity

description: The project consists in the study and analysis of the chemical information that can be obtained in the presence of an electric quadrupole moment of the nuclei. Such a quadrupole moment indicates a non-spherical charge distribution of the nucleus and will couple to the electric field gradient associated with the other nuclei as well as the electrons of the molecule. Calculations of the electric field gradient combined with experiment allows the extraction of the value of the electric quadrupole moment of the nucleus but also provides information about the electronic structure, notably the bonding situation, in the molecule. We explored this using the so-called Townes–Dailey model in a relativistic framework. The 35Cl isotope was investigated in detail in different molecular environments, but also 238U isotope in the UO_{2}^{2+} was studied, to verify the Townes-Dailey model in systems presenting d and f valence orbitals. The contribution of the different atomic orbitals to the electric field gradient was evaluated using projection analysis, a linear combination of atomic orbitals approach based on the expansion of the molecular orbitals in pre-calculated occupied atomic orbitals of the atom (or site).

description: In this paper we present the Clustering-Labels-Score Patterns Spotter (CLaSPS), a new methodology for the determination of correlations among astronomical observables in complex datasets, based on the application of distinct unsupervised clustering techniques. The novelty in CLaSPS is the criterion used for the selection of the optimal clusterings, based on a quantitative measure of the degree of correlation between the cluster memberships and the distribution of a set of observables, the labels, not employed for the clustering. In this paper we discuss the applications of CLaSPS to two simple astronomical datasets, both composed of extragalactic sources with photometric observations at different wavelengths from large area surveys. The first dataset, CSC+, is composed of optical quasars spectroscopically selected in the SDSS data, observed in the X-rays by Chandra and with multi-wavelength observations in the near-infrared, optical and ultraviolet spectral intervals. One of the results of the application of CLaSPS to the CSC+ is the re-identification of a well-known correlation between the alphaOX parameter and the near ultraviolet color, in a subset of CSC+ sources with relatively small values of the near-ultraviolet colors. The other dataset consists of a sample of blazars for which photometric observations in the optical, mid and near infrared are available, complemented for a subset of the sources, by Fermi gamma-ray data. The main results of the application of CLaSPS to such datasets have been the discovery of a strong correlation between the multi-wavelength color distribution of blazars and their optical spectral classification in BL Lacs and Flat Spectrum Radio Quasars and a peculiar pattern followed by blazars in the WISE mid-infrared colors space. This pattern and its physical interpretation have been discussed in details in other papers by one of the authors.

description: The structure and magnetic properties of Co clusters, comprising from 26 to 2700 atoms, self-organized or not on the graphene/Ir(111) moiré, were studied in situ with the help of scanning tunneling microscopy and X-ray magnetic circular dichroism. Surprisingly the small clusters have almost no magnetic anisotropy. We find indication for a magnetic coupling between the clusters. Experiments have to be performed carefully so as to avoid cluster damage by the soft X-rays.
The picture of the Bianchi I model via gauge fixing in Loop Quantum Gravity

description: The implications of the SU(2) gauge fixing associated with the choice of invariant triads in Loop Quantum Cosmology are discussed for a Bianchi I model. In particular, via the analysis of Dirac brackets, it is outlined how the holonomy-flux algebra coincides with the one of Loop Quantum Gravity if paths are parallel to fiducial vectors only. This way the quantization procedure for the Bianchi I model is performed by applying the techniques developed in Loop Quantum Gravity but restricting the admissible paths. Furthermore, the local character retained by the reduced variables provides a relic diffeomorphisms constraint, whose imposition implies homogeneity on a quantum level. The resulting picture for the fundamental spatial manifold is that of a cubical knot with attached SU(2) irreducible representations. The discretization of geometric operators is outlined and a new perspective for the super-Hamiltonian regularization in Loop Quantum Cosmology is proposed.

description: We report here the first results of a multi-wavelength campaign focussing on magnetospheric accretion processes within the close binary system V4046 Sgr, hosting two partly-convective classical T Tauri stars of masses ~0.9 Msun and age ~12 Myr. In this paper, we present time-resolved spectropolarimetric observations collected in 2009 September with ESPaDOnS at the Canada-France-Hawaii Telescope (CFHT) and covering a full span of 7d or ~2.5 orbital/rotational cycles of V4046 Sgr. Small circularly polarised Zeeman signatures are detected in the photospheric absorption lines but not in the accretion-powered emission lines of V4046 Sgr, thereby demonstrating that both system components host large-scale magnetic fields weaker and more complex than those of younger, fully-convective cTTSs of only a few Myr and similar masses. Applying our tomographic imaging tools to the collected data set, we reconstruct maps of the large-scale magnetic field, photospheric brightness and accretion-powered emission at the surfaces of both stars of V4046 Sgr. We find that these fields include significant toroidal components, and that their poloidal components are mostly non-axisymmetric with a dipolar component of 50-100G strongly tilted with respect to the rotation axis; given the similarity with fields of partly-convective main-sequence stars of similar masses and rotation periods, we conclude that these fields are most likely generated by dynamo processes. We also find that both stars in the system show cool spots close to the pole and extended regions of low-contrast, accretion-powered emission; it suggests that mass accretion is likely distributed rather than confined in well defined high-contrast accretion spots, in agreement with the derived magnetic field complexity.

description: Within the clinical interview, the general review of systems has four main objectives: to evaluate the past and present health of each body system, to double check for omitted patient information from the present illness, to promote healthy living and offer patient education. Medical students have difficulty learning this interview section through its focused use of questions that could relate to a multitude of possible medical symptoms. Educators strive to assist students organize their knowledge and enhance their communication skills. The quality of patient data is related to the type of questions that are asked. The PROS concept was created as fourteen different questions, with clinical content validated by the medical literature, that review major medical diseases and their illness effects, blending medical and patient centered approaches. This research tested the feasibility and reliability of the PROS instrument with first year medical students who used this format as part of their clinical interview with simulated patients (SPs) at the University of Calgary. Data collection occurred through videotaped student interviews that involved nine different medical case scenarios. The evaluation assessed the completeness of questions, the scope of added clinical content, the performance time and the understanding ability of SPs to correctly answer the PROS questions based upon their clinical scripts. Results were favorable on these four measures, supporting the PROS as a valuable clinical instrument. Its potential application towards teaching medical trainees, implementation into clinical practice, and proposed future research suggest worthwhile promise for furthering its development.

description: We report positive muon spin relaxation measurements on the triangular lattice magnetic system FeGa2S4. A magnetic transition not previously detected by specific heat and magnetic susceptibility measurements is found in zero field at T^* \simeq 30 K. It is observed through the temperature dependencies of the signal amplitude and the spin-lattice relaxation rate. This transition is therefore not a conventional magnetic phase transition. Since persistent spin dynamics is observed down to 0.1 K, the ground state cannot be of the canonical spin-glass type, which could be suggested from hysteresis effects in the bulk susceptibility below T_f \simeq 16 K. These results are compared to those found for the isomorph NiGa2S4. It is argued that the fate of the transition, which has been interpreted in terms of the Z_2 topological transition in this latter system, is probably different in FeGa2S4.

Lifestyles of youth in auto theft: an exploratory study
Creators: name: Drozda, Christopher
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 77-79
description: The literature on auto theft is sparse and research has focused primarily from the quantitative viewpoint, thus motivations behind the act have been inadequately explored. In this study twelve juveniles were interviewed on the motivations of auto theft. The lifestyle of these juveniles consists of a self-interpretation of boredom that prevailed in their everyday lives. For the juveniles it is not just the thrill of auto theft, but the perception of controlling the risk involved in "getting away with it." Further, the auto theft lifestyle is based on the pursuit of casual leisure (Stebbins, 1997) allowing for an innovative approach to discovering the motivations of crime. The motivations of auto theft are contextualized as thrill and risk with a hedonic lifestyle as a means to an end. This means to an end comes from the theft itself as a leisure activity or as an intermediate step to other leisure activities.
Optimal retirement consumption with a stochastic force of mortality

Year: 2012
Subjects: subject: Risk Management (q-fin.RM)

description: We extend the lifecycle model (LCM) of consumption over a random horizon (a.k.a. the Yaari model) to a world in which (i.) the force of mortality obeys a diffusion process as opposed to being deterministic, and (ii.) a consumer can adapt their consumption strategy to new information about their mortality rate (a.k.a. health status) as it becomes available. In particular, we derive the optimal consumption rate and focus on the impact of mortality rate uncertainty vs. simple lifetime uncertainty -- assuming the actuarial survival curves are initially identical -- in the retirement phase where this risk plays a greater role. In addition to deriving and numerically solving the PDE for the optimal consumption rate, our main general result is that when utility preferences are logarithmic the initial consumption rates are identical. But, in a CRRA framework in which the coefficient of relative risk aversion is greater (smaller) than one, the consumption rate is higher (lower) and a stochastic force of mortality does make a difference. That said, numerical experiments indicate that even for non-logarithmic preferences, the stochastic mortality effect is relatively minor from the individual's perspective. Our results should be relevant to researchers interested in calibrating the lifecycle model as well as those who provide normative guidance (a.k.a. financial advice) to retirees.

description: We show theoretically that specular Andreev reflection occurs stably at altermagnet--superconductor interfaces, which is a phenomenon that has previously been predicted only in a limited range of materials, such as Dirac/Weyl materials with fine-tuned chemical potentials. Furthermore, the characteristic spin-split bands of the altermagnet lead to a distinctive spin polarization in the specular Andreev reflections. By utilizing this feature, we propose a device that integrates the functions of both a Cooper pair splitter and a spin beam splitter, thereby creating energy-entangled electron pairs. The positive nonlocal conductance and the positive noise cross-correlation are unambiguous signatures of specular Andreev reflections in the proposed device.

description: We report our theoretically investigation on the spin-orbit coupling and $g$-factor of the $X$-valley in cubic GaN. We find that the spin-orbit coupling coefficient from $sp^3d^5s^\ast$ tight-binding model is 0.029\,eV$\cdot$Å, which is comparable with that in cubic GaAs. By employing the ${\bf k}\cdot{\bf p}$ theory, we find that the $g$-factor in this case is only slightly different from the free electron $g$-factor. These results are expected to be important for the on-going study on spin dynamics far away from equilibrium in cubic GaN.

Design and realization of an explanation component for software release planning
Creators: name: Du, Gengshen

Year: 2004

description: Bibliography: p. 119-128
description: Project planning is an early step in software development and it plays an important role in determining the success or failure of the software engineering practice in the course of software development. One typical aspect of project planning is release planning, in which requirements are grouped into temporarily ordered releases and the ordering within the releases is left to a later decision. In software development industry, release planning is of increasing importance and is increasingly accepted as an essential means to achieve better project results. However, the inherent problem in release planning is its highly complex and uncertain nature. Many aspects of release planning, including the objectives, constraints or effort estimates, are often imprecisely and informally stated by different stakeholders. Because of both the complexity and uncertainty of the problem, planning and prioritization results have to be complemented by other approaches. ReleasePlanner™ is an intelligent decision support tool for release planning based on the EVOLVE* methodology. In this thesis I propose an explanation component, EXPLAIN-RP, which is aimed to supplement and improve the support capabilities of ReleasePlanner™. The main contribution of my research is to integrate EXPLAIN-RP into the current EVOLVE* methodology in terms of its specification, design, and initial prototype realization. They are the basis for a more comprehensive explanation component in the future research. In more detail, main achievements of the thesis are: (i) high level design of an explanation component as part of an existing decision support system for software release planning, (ii) taxonomy of questions and answers to guide the dialogue between the user and the system, (iii) detailed design and initial implementation of EXPLAIN-RP, and (iv) illustration of the approach by a case study in the area of enterprise application integration.

description: The measurement of the positions, distances, motions and luminosities of stars represents the foundations of modern astronomical knowledge. Launched at the end of the eighties, the ESA Hipparcos satellite was the first space mission dedicated to such measurements. Hipparcos improved position accuracies by a factor of 100 compared to typical ground-based results and provided astrometric and photometric multi-epoch observations of 118,000 stars over the entire sky. The impact of Hipparcos on astrophysics has been extremely valuable and diverse. Building on this important European success, the ESA Gaia cornerstone mission promises an even more impressive advance. Compared to Hipparcos, it will bring a gain of a factor 50 to 100 in position accuracy and of a factor of 10,000 in star number, collecting photometric, spectrophotometric and spectroscopic data for one billion celestial objects. During its 5-year flight, Gaia will measure objects repeatedly, up to a few hundred times, providing an unprecedented database to study the variability of all types of celestial objects. Gaia will bring outstanding contributions, directly or indirectly, to most fields of research in astrophysics, such as the study of our Galaxy and of its stellar constituents, the search for planets outside the solar system.

description: A laboratory prototype spectral/spatial interferometer has been constructed to demonstrate the feasibility of the double Fourier technique at Far Infrared (FIR) wavelengths (0.15 - 1 THz). It is planned to use this demonstrator to investigate and validate important design features and data processing methods for future astronomical FIR interferometer instruments. In building this prototype we have had to address several key technologies to provide an end-end system demonstration of this double Fourier interferometer. We report on the first results taken when viewing single slit and double slit sources at the focus of a large collimator used to simulate real sources at infinity. The performance of the prototype instrument for these specific field geometries is analyzed to compare with the observed interferometric fringes and to demonstrate image reconstruction capabilities.

description: Energy Management Systems (EMSs) are used to monitor energy consumption in buildings with the purpose of improving energy efficiency, by identifying savings opportunities and misuse situations. To achieve that, an EMS collects energy metering data streams from a network of energy meters deployed in a building. Sensor data must be processed in (near ) real-time, to support a timely decision making process. Currently, EMSs are using traditional DBMSs to process these data, introducing a persistence step that translates to an unacceptable latency on data evaluation. Moreover, sensor data monitoring queries are not elegantly supported by the SQL query language, thus hampering the ability of an EMS to process energy metering data in real-time. Data Stream Management Systems (DSMSs) are used to process data streams efficiently in several domains. Many sensor network monitoring applications have been implemented upon DSMSs resulting in significant improvements on performance and overall resource usage. This thesis validates the hypothesis that, to process energy metering data streams in real-time, EMSs should be supported by DSMSs, instead of DBMSs. We introduce an EMS’s Data Processing Architecture supported by a DSMS that supports the implementation of an EMS capable of performing real-time data processing. We validate our solution through a comparative evaluation against a DBMS based architecture. The results show that the DSMS-based EMS outperformed the state of the art approach, both in data evaluation latency and query language expressibility—demonstrating its adequacy to process energy metering data streams in real-time.

description: In this paper, we study topological quantum mechanical models on symplectic orbifolds. The correlation map gives an explicit orbifold version of quantum HKR map. The exact semi-classical approximation in this model leads to a geometric and quantum field theoretic interpretation of the orbifold algebraic index.

description: Keywords: Declarations of Interdependence Bill of Responsibility Inalienable rights Laws of Nature Life, Liberty and the Pursuit of Happiness Thomas jefferson Principles The tyrannies caused through the actions of King George the III became the cause of a new idea. The idea birthed was the right of each individual to life, liberty and the pursuit of happiness and was documented as the Declaration of Independence. Today's tyrannies are not single sourced but are challenging the experience of life, liberty and the pursuit of happiness. My search for solutions to the tyrannies in todays architectural practices led me to look for solutions through the same foundational principles Jefferson used when he wrote the Declaration of Independence and created Monticello. The idea of life and liberty in contemporary times is expanded to include all life forms and that that which sustains life. Declarations of Interdependence and a Bill of Responsibility are proposed based on the study of Jefferson's democratic and architectural activities. It could be that fully functioning democracy would render the concept of sustainability redundant.

The Tidal Disruption of Giant Stars and Their Contribution to the Flaring Supermassive Black Hole Population

description: Sun-like stars are thought to be regularly disrupted by supermassive black holes (SMBHs) within galactic nuclei. Yet, as stars evolve off the main sequence their vulnerability to tidal disruption increases drastically as they develop a bifurcated structure consisting of a dense core and a tenuous envelope. Here we present the first hydrodynamic simulations of the tidal disruption of giant stars and show that the core has a substantial influence on the star's ability to survive the encounter. Stars with more massive cores retain large fractions of their envelope mass, even in deep encounters. Accretion flares resulting from the disruption of giant stars should last for tens to hundreds of years. Their characteristic signature in transient searches would not be the $t^{-5/3}$ decay typically associated with tidal disruption events, but a correlated rise over many orders of magnitude in brightness on months to years timescales. We calculate the relative disruption rates of stars of varying evolutionary stages in typical galactic centers, then use our results to produce Monte Carlo realizations of the expected flaring event populations. We find that the demographics of tidal disruption flares are strongly dependent on both stellar and black hole mass, especially near the limiting SMBH mass scale of $\sim 10^8 M_\odot$. At this black hole mass, we predict a sharp transition in the SMBH flaring diet beyond which all observable disruptions arise from evolved stars, accompanied by a dramatic cutoff in the overall tidal disruption flaring rate. Black holes less massive than this limiting mass scale will show observable flares from both main sequence and evolved stars, with giants contributing up to 10% of the event rate. The relative fractions of stars disrupted at different evolutionary states can constrain the properties and distributions of stars in galactic nuclei other than our own.

description: Recent advances in anti-malware technologies have steered the security industry away from maintaining vast signature databases and into newer defence technologies such as behaviour blocking, application whitelisting and others. Most would agree that the reasoning behind this is to keep up with the arms race established between malware writers and the security community almost three decades ago. Still, malware writers have not as yet created new paradigms. Indeed, malicious code development is still largely limited to code pattern changes utilizing polymorphic and metamorphic engines, as well as executable packer and wrapper technologies. Each new malware instance retains the exact same core functionality as its ancestor and only alters the way it looks. What if, instead, malware were able to change its function or behaviour autonomously? What if, in the absence of human intervention, computer viruses resembled biological viruses in their ability to adapt to new defence technologies as soon as they came into effect? In this paper, we will provide the theoretical proof behind malware implementation that closely models Darwinian evolution.

description: When intense laser pulses release correlated electrons, the time delay between the ionizations may last more than one laser cycle. We show that this "Recollision-Excitation with Subsequent Ionization" pathway originates from the inner electron being promoted to a sticky region by a recollision where it is trapped for a long time before ionizing. We identify the mechanism which regulates this region, and predict oscillations in the double ionization yield with laser intensity.
