description: We present a general methodology to obtain the basis of qudits which are admissible to Quantum Fourier Transform (QFT). We first study this method for qubits to characterize the ensemble that works for the Hadamard transformation (QFT for two dimension). In this regard we identify certain incompleteness in the result of Maitra and Parashar (IJQI, 2006). Next we characterize the ensemble of qutrits for which QFT is possible. Further, some theoretical results related to higher dimensions are also discussed.

description: Abstract:
 Joint and consistent analysis of model simulations and observations of the Atlantic Meridional Overturning Circulation (AMOC) is important to advance our understanding of its trends, variability, and mechanisms as well as its latitudinal coherency. It is important that such model – observations comparisons use the same or as-close-as-practically-possible methods as applied in observations to provide apples-to-apples comparisons. Considering the Meridional Overturning Variability Experiment (MOVE) array at 16°N, the RAPID Array at 26.5°N, the South Atlantic MOC Basin-wide Array (SAMBA) at 34.5°S, and the Overturning in the Subpolar North Atlantic Program (OSNAP) array at 57°N, we revisit the underlying assumptions used to calculate their respective transports in comparison to transports from an eddying ocean hindcast simulation where transports obtained using the same observational methods can be directly compared against model truth. Our analysis reveals significant sensitivity of simulated and observed transports and their variability and trends to various reference level assumptions. Indeed, given i) the short observational records, ii) strong dependencies of transport estimates to their barotropic / compensating components, and iii) the presence of large interannual-to-decadal timescale variability, whether AMOC has been declining or not during the last couple of decades cannot be meaningfully determined. In general, simulated variability is weaker than in observations, particularly for the 9-site SAMBA estimate. We show reasons for these differences, considering contributions of transport components and the underlying transport assumptions associated with the observational methods. We also discuss complementarity of depth- and density-space AMOC depictions.

description: The radio properties of blazars detected by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope have been observed contemporaneously by the Very Long Baseline Array (VLBA). In total, 232 sources were observed with the VLBA. Ninety sources that were previously observed as part of the VLBA Imaging and Polarimetry Survey (VIPS) have been included in the sample, as well as 142 sources not found in VIPS. This very large, flux-limited sample of active galactic nuclei (AGN) provides insights into the mechanism that produces strong gamma-ray emission. In particular, we see that gamma-ray emission is related to strong, uniform magnetic fields in the cores of the host AGN. Included in this sample are non-blazar AGN such as 3C84, M82, and NGC 6251. For the blazars, the total VLBA radio flux density at 5 GHz correlates strongly with gamma-ray flux. The LAT BL Lac objects tend to be similar to the non-LAT BL Lac objects, but the LAT flat-spectrum radio quasars (FSRQs) are significantly different from the non-LAT FSRQs. Strong core polarization is significantly more common among the LAT sources, and core fractional polarization appears to increase during LAT detection.

description: Interstellar filaments are an important part of star formation. To understand the structure of filaments, cross-section profiles are often fitted with Plummer profiles. This profiling is often done with submm studies, such as Herschel. It would be convenient if filament properties could also be studied using groundbased NIR data. We compare the filament profiles obtained by NIR extinction and submm observations to find out if reliable profiles can be derived using NIR data. We use J-, H-, and K-band data of a filament north of TMC-1 to derive an extinction map from colour excesses of background stars. We compare the Plummer profiles obtained from extinction maps with Herschel dust emission maps. We present 2 methods to estimate profiles from NIR: Plummer profile fits to median Av of stars or directly to the Av of individual stars. We compare the methods by simulations. In simulations extinction maps and the new methods give correct results to within ~10-20 for modest densities. Direct fit to data on individual stars gives more accurate results than extinction map, and can work in higher density. In profile fits to real observations, values of Plummer parameters are generally similar to within a factor of ~2. Although parameter values can vary significantly, estimates of filament mass usually remain accurate to within some tens of per cent. Our results for TMC-1 are in agreement with earlier results. High resolution NIR data give more details, but 2MASS data can be used to estimate profiles. NIR extinction can be used as an alternative to submm observations to profile filaments. Direct fits of stars can also be a valuable tool. Plummer profile parameters are not always well constrained, and caution should be taken when making fits. In the evaluation of Plummer parameters, one can use the independence of dust emission and NIR data and the difference in the shapes of the confidence regions.

Joint analysis of TDMA and geographic routing for a large scale wireless mesh network
Creators: name: Lübkert, Tobias
Publisher: name: TUHH Universitätsbibliothek
Year: 2015
Subjects: classificationCode: 004
subject: Informatik

description: Wireless Mesh Networks are a promising technique for large scale networks with low-power and high reliability requirements such as in industrial plants. The shared transmission medium requires a medium access control mechanism which reduces the amount of parallel transmission, because nearby simultaneous transmitting devices hinder the successful reception at the destination device. The common CSMA-CA mechanism cannot satisfy the reliability requirement of an industrial plant, as many messages get dropped when the channel is busy for too long. Current standards introduce TDMA schemes for wireless mesh networks to improve the reliability with higher throughput and deterministic latency. In this work these standards are reviewed and one of the specified TDMA protocols, the deterministic synchronous multi-channel extension (DSME), is analyzed in more detail by examining its performance analytically and also by simulation. For this purpose, a simulation model was implemented, which is used to simulate an example network utilizing DSME and a promising geographic routing algorithm for a solar tower power plant. The introduced analytical model allows to determine the maximum performance for a network using DSME. The simulation results show that DSME achieves a strongly improved packet loss probability compared to CSMA-CA.
On the origin of the stellar halo and multiple stellar populations in the globular cluster NGC 1851

description: We propose that the observed stellar halo around the globular cluster (GC) NGC 1851 is evidence for its formation in the central region of its defunct host dwarf galaxy. We numerically investigate the long-term dynamical evolution of a nucleated dwarf galaxy embedded in a massive dark matter halo under the strong tidal field of the Galaxy. The dwarf galaxy is assumed to have a stellar nucleus (or a nuclear star cluster) that could be the progenitor for NGC 1851. We find that although the dark matter halo and the stellar envelope of the host dwarf of NGC 1851 can be almost completely stripped during its orbital evolution around the Galaxy, a minor fraction of stars in the dwarf can remain trapped by the gravitational field of the nucleus. The stripped nucleus can be observed as NGC 1851 with no/little dark matter whereas stars around the nucleus can be observed as a diffuse stellar halo around NGC 1851. The simulated stellar halo has a symmetric distribution with a power-law density slope of ~ -2 and shows no tidal tails within ~200pc from NGC 1851. We show that two GCs can merge with each other to form a new nuclear GC embedded in field stars owing to the low stellar velocity dispersion of the host dwarf. This result makes no assumption on the ages and/or chemical abundances of the two merging GCs. Thus the observed stellar halo and characteristic multiple stellar populations in NGC 1851 suggest that NGC 1851 could have formed initially in the central region of an ancient dwarf galaxy.

Die Überlasten bewirken, abhängig von der Wechselwirkung der Überlastmechanismen, eine Beschleunigung oder Verzögerung des Rissfortschritts. Als neuer, das vorherrschende Verzögerungsverhalten kontrollierender Mechanismus wurde die Zunahme der mikroskopischen Bruchflächenrauigkeit durch die Bildung von Stufen in Rissausbreitungsrichtung aufgrund der Überlasten entdeckt.
description: The influence of periodically applied overloads on fatigue crack propagation was examined for each a fine and a coarse grained aluminium alloy AA 2024 T3, alloys AA 6156 T62 and AA 7349 T76511, as well as a fine bi-modal and a coarse lamellar microstructure of titanium alloy Ti-6Al-4V. The overloads result in acceleration or retardation of crack growth rate depending on the interaction of the overload mechanisms. As new mechanism, controlling the predominant retardation behaviour, the increase in microscopic roughness of the fracture surface due to steps parallel to the direction of crack propagation created by the overloads was revealed.

Dadurch wird es möglich, Hochfrequenz Referenzsignale femtosekundengenau zu stabilisieren. Ein gepulstes optisches Synchronisationssystem wird zur Bereitstellung der optischen Referenzsignale verwendet. Der L2RF-Phasendetektor basiert auf einem integrierten Mach-Zehnder-Modulator (MZM), in dem der Phasenfehler dem optischen Pulszug in Form einer Amplitudenmodulation aufgeprägt wird. Verschiedene Konfigurationen des L2RF Phasendetektors wurden für unterschiedliche Betriebsbedingungen evaluiert. Die vollständige Übertragungsfunktion des Phasendetektors wurde anschließend unter dem Einfluss verschiedener Störgrößen mathematisch analysiert. Die Genauigkeit wurde anhand zweier Prototypen verifiziert. Die gezeigte Stabilität von 3,6fs in 12h ist für einen L2RF Phasendetektor unübertroffen.
description: The invention of a femtosecond stable Laser-to-RF phase detector allows to measure with femtosecond precision the relative phase between a phase stable optical reference and an RF signal. Thereby one can stabilize RF reference signals in modern FELs on a femtosecond scale. A pulsed optical synchronization system is used to deliver the required optical reference signals. The L2RF phase detector is based on an integrated Mach-Zehnder modulator (MZM) in which the phase error between both signals is encoded in an amplitude modulation of the optical pulse train. Different configurations for different operation scenarios have been evaluated. A full mathematical representation has been derived. The impact of multiple error sources has been investigated. Error sources of the measurement setup have been identified and eliminated. The femtosecond performance has been verified with two different prototypes. The achieved stability of 3.6fs over 12h is currently unmatched.

Oxidized low density lipoprotein regulates apoptosis and growth factor production in macrophages
Creators: name: Riazy, Maziar
Publisher: name: University of British Columbia
Year: 2010

description: Macrophages and oxidized LDL (oxLDL) both play key roles in the pathogenesis of atherogenesis. This thesis is focused on the effects of oxLDL on macrophage cytokine secretion and macrophage survival. The first project defines some of the mechanisms by which oxLDL increases secretion of vascular endothelial growth factor (VEGF), a pro-inflammatory growth factor known to be involved in atherogenesis. We show that both the protein and lipid components of oxLDL contribute to induction of VEGF secretion. Disruption of the genes for CD36, SR-A, or LOX-1 scavenger receptors had no effect. The atypical protein kinase c (PKCζ) was activated by oxLDL, and this activation was essential for the induction of VEGF. OxLDL could be atherogenic through increasing macrophage number within the plaque. Our group has previously shown that oxLDL induces growth and inhibits apoptosis in macrophages. In the second project, we sought to determine if members of the scavenger receptor family were required for the prosurvival effect of oxLDL in macrophages. We used mouse strains lacking different scavenger receptors and found that oxLDL-mediated survival is not dependent on CD36, SR-A, LOX-1, TLR4, its signaling partner CD14, or FcγRIIb. Significant inhibition of oxLDL uptake by a combined inactivation of CD36 and SR-A did not reduce the prosurvival effect of oxLDL. In the third project, we sought to characterize the oxidative modification of LDL that is responsible for the prosurvival effect. We found that both protein and lipid components of oxLDL can induce growth in macrophages. This seems to be mediated by modification of amino groups in apoB or in phosphatidylethanolamine by lipid peroxidation products. Further characterization of these oxidation products suggested that unfragmented hydroperoxide or endoperoxide-containing oxidation products of linoleic acid and arachidonic acid derivatize amino groups. When LDL or other proteins are modified in this fashion, they acquire the ability to induce pro-survival signaling pathways in macrophages. HPLC-MSMS studies showed that some of the arachidonic acid-derived lysine adducts are isolevuglandin (isoLG)-derived adducts that contain lactam and hydroxylactam rings. MSMS analysis of linoleic acid autoxidation adducts was consistent with 5 or 6 membered nitrogen-containing heterocycles derived from unfragmented oxidation products.

description: We have studied the structure of hot accretion flow bathed in a general large-scale magnetic field. We have considered magnetic parameters $ β_{r,φ,z}[=c^2_{r,φ,z}/(2c^2_{s})] $, where $ c^2_{r, φ, z} $ are the Alfvén sound speeds in three direction of cylindrical coordinate $ (r,φ,z) $. The dominant mechanism of energy dissipation is assumed to be the magnetic diffusivity due to turbulence and viscosity in the accretion flow. Also, we adopt a more realistic model for kinematic viscosity $ (ν=αc_{s} H) $, with both $ c_{s} $ and $ H $ as a function of magnetic field. As a result in our model, the kinematic viscosity and magnetic diffusivity $ (η=η_{0}c_{s} H) $ are not constant. In order to solve the integrated equations that govern the behavior of the accretion flow, a self-similar method is used. It is found that the existence of magnetic resistivity will increase the radial infall velocity as well as sound speed and vertical thickness of the disk. However the rotational velocity of the disk decreases by the increase of magnetic resistivity. Moreover, we study the effect of three components of global magnetic field on the structure of the disk. We found out that the radial velocity and sound speed are Sub-Keplerian for all values of magnetic field parameters, but the rotational velocity can be Super-Keplerian by the increase of toroidal magnetic field. Also, Our numerical results show that all components of magnetic field can be important and have a considerable effect on velocities and vertical thickness of the disk.

In our formalism, the excitonic gain medium is described by classical rate equations, while the polariton modes are described fully quantum mechanically. We show the equivalence of our method with a master equation approach. As an application, we compute the linewidth of a single mode polariton condensate. Both the line broadening due to the interactions between polaritons and the interactions with the reservoir excitons is taken into account.

Magnetic properties near the surface of cuprate superconductors studied using Beta-Detected NMR
Creators: name: Saadaoui, Hassan
Publisher: name: University of British Columbia
Year: 2010

description: Beta-detected Nuclear Magnetic Resonance (β-NMR) uses highly spin polarized β-emitting nuclei as a probe. Besides its use in nuclear physics, it has also become a powerful and sensitive tool in condensed matter physics and materials science. At TRIUMF, β-NMR of ⁸Li+ has been developed to study materials in a depth-resolved manner, where the implantation depth of ⁸Li+ is controlled via electrostatic deceleration. In this thesis, β-NMR of ⁸Li+ has been used to study high-Tc cuprate superconductors (HTSC). The objective of this work is to search for spontaneous magnetic fields generated by a possible time-reversal symmetry breaking (TRSB) superconducting state near the surface of hole-doped YBa₂Cu₃O₇−d (YBCO), and study the nature of the vortex lattice (VL) in YBCO and electron-doped Pr₂−xCexCuO₄−d (PCCO). For several advantages, our measurements were carried out by implanting ⁸Li+ in thin silver films evaporated on the superconductors. In our TRSB studies, the magnetic field distribution p(B) is measured 8 nm away from the Ag/YBCO interface in magnetic fields B₀ = 5 to 100 G, applied parallel to the interface. p(B) showed significant broadening below the Tc of ab- and c-axis oriented YBCO films. The broadening signals the existence of weak disordered magnetic fields near the surface of YBCO. From the broadening’s temperature and field dependence we draw an upper limit of 0.2 G on the magnitude of spontaneous magnetic fields associated with TRSB. To study the VL, p(B) is measured at average implantation depths ranging from 20 to 90 nm away from the Ag/YBCO or Ag/PCCO interface in B₀ = 0.1 to 33 kG, applied perpendicular to the surface. p(B) showed a dramatic broadening below Tc as expected from the emerging field lines of the VL in the superconductor. In YBCO, p(B) is symmetric and the dependence on B0 is much weaker than expected from an ideal VL, indicating that the vortex density varies across the face of the sample on a long length scale, likely due to vortex pinning at twin boundaries. In PCCO, a 2D VL is established due to the high anisotropy of the superconductor leading to a nearly symmetric p(B).

description: Abstract:
 As a result of the AMOC the North Atlantic absorbs a disproportionately large amount of carbon for its area. Using observations from RAPID-MOCHA, Argo and GO-SHIP at 26N we reconstruct time series of anthropogenic carbon and inorganic nutrient transports into the North Atlantic. On average half of the anthropogenic carbon that is accumulating in the North Atlantic is transported into the region across 26N, the remainder comes from local air-sea fluxes. While most of the variance in the northward anthropogenic carbon transport can be described by variability in the strength of the AMOC there is a significant contribution form the increasing anthropogenic carbon concentrations, preferentially accumulating in the near-surface. The persistently southward nutrient transports across 26N exceed external nutrient sources and thus in themselves indicate non steady-state behaviour. In addition increasing remineralised:preformed nutrient ratios at 26N indicate further non steady-state behavoiur and regionally increasing biological carbon pump efficiency consistent with a transient response to circulation changes.

description: Knowledge mining is the process of deriving new and useful knowledge from vast volumes of data and background knowledge. Modern healthcare organizations regularly generate huge amount of electronic data stored in the databases. These data are a valuable resource for mining useful knowledge to help medical practitioners making appropriate and accurate decision on the diagnosis and treatment of diseases. In this paper, we propose the design of a novel medical expert system based on a logic-programming framework. The proposed system includes a knowledge-mining component as a repertoire of tools for discovering useful knowledge. The implementation of classification and association mining tools based on the higher order and meta-level programming schemes using Prolog has been presented to express the power of logic-based language. Such language also provides a pattern matching facility, which is an essential function for the development of knowledge-intensive tasks. Besides the major goal of medical decision support, the knowledge discovered by our logic-based knowledge-mining component can also be deployed as background knowledge to pre-treatment data from other sources as well as to guard the data repositories against constraint violation. A framework for knowledge deployment is also presented.

description: In this paper, based on the mean field approach and random-phase-approximation, we study the magnetic properties of the spinful Haldane model on honeycomb lattice of topological flat band with on-site repulsive Coulomb interaction. We find that the antiferromagnetic (AF) order is more stable than ferromagnetic (FM) order at (or near) half-filling; while away from half-filling the phase diagram becomes complex: At large doping, FM order is more stable than AF order due to the flatness of band structure. In particular, we find that at quarter filling case, the system becomes a Q=1$ topological insulator which is induced by the FM order.

description: A morphism h is unambiguous with respect to a word w if there is no other morphism g that maps w to the same image as h. In the present paper we study the question of whether, for any given word, there exists an unambiguous 1-uniform morphism, i.e., a morphism that maps every letter in the word to an image of length 1.

Understanding barriers to educational attainment among Canadian youth.
Creators: name: Foley, Kelly
Publisher: name: University of British Columbia
Year: 2010

description: In this dissertation, I explore barriers to educational attainment faced by Canadian youth from three different perspectives. The first paper, which is joint with David Green and Giovanni Gallipoli, uses an extended version of an unobserved factor model to investigate the factors that influence a youth’s decision to drop out of high-school. Our results support three main conclusions. First, ability at age 15 plays an important role in dropping out. Second, parental valuation of education has a substantial impact on medium and low ability teenagers. Third, parental education has no direct effect on dropping out once we control for ability and parental valuation of education. The second paper poses the question ”Can neighbourhoods change the decisions of youth on the margin of university participation?” I use the fraction of adults who have at least a Bachelors degree in a small geographic area surrounding a youth’s home to proxy one source of potential peers and role models. Results suggest that at the mean neighbourhoods have a substantial impact on the likelihood of attending university. I further explore this finding by estimating the marginal effect of neighbourhood characteristics at different points on the socio-economic distribution, and the distribution of reading test scores. One striking finding is that while university participation among youth from families with university degrees is unaffected by neighbourhoods, the marginal effect of neighbourhoods is largest for the highskilled youth from lower socio-economic backgrounds. The final paper evaluates the impact of a post-secondary preparatory course on high school achievement. BC AVID, a pilot project implemented with a random assignment design, encouraged students whose grade 8 grades were within the B and C range to enrol in advanced classes and provided academic support through an elective course. I find that while the program increased the chances that students enrolled in an advanced math course, it also increased the likelihood that students failed the provincial examination. BC AVID did, however, help students pass their course work and as a result more students obtained credit for the advanced math course.

description: The simultaneous integration of knowledge acquisition and development of clinical reasoning in preclinical medical education remains a challenge. To help address this challenge, the authors developed and implemented the Student-Generated Reasoning Tool (SGRT)—a tool asking students to propose and justify pathophysiological hypotheses, generate findings, and critically appraise information. In 2019, students in a first-year preclinical course (n = 171; SGRT group) were assigned to one of 20 teams. Students used the SGRT individually, then in teams, and faculty provided feedback. The control group (n = 168) consisted of students from 2018 who did not use SGRT. Outcomes included academic performance, effectiveness of collaborative environments using the SGRT, and student feedback. Students were five times more likely to get questions correct if they were in the SGRT group versus control group. Accuracy of pathophysiological hypotheses was significantly lower for individuals than teams. Qualitative analysis indicated students benefited from generating their own data, justifying their reasoning, and working individually as well as in teams. This study introduces the SGRT as a potentially engaging, case-based, and collaborative learning method that may help preclinical medical students become aware of their knowledge gaps and integrate their knowledge in basic and clinical sciences in the context of clinical reasoning.

description: This exploratory research project was designed to create new knowledge about some of the hunter-gatherer adaptation patterns in the Upper Yellowstone Valley and the Northern Rocky Mountains. The study begins with the working assumption that the Northern Rocky Mountains are a distinct archaeological macro-environment that must be investigated through regional research designs. The Upper Yellowstone Valley was selected as one of these regions, and the Myers­Hindman site, an open camp in the Mountain Flanks Life Zone, was desig­nated for excavation. The resultant data base from these excavations consists of seven identified settlement units which cover a time span from about 7000 B.C. to A.D. 1200, a sample of some 6,610 artifactual specimens. and a faunal assemblage of 600 elements representing fifteen large- and small-game species. Analyses of these data, plus those from the valley in general, indicate that the region has seen continuity in man-environmental relations for at least the past 9000 years. Although numerous specific and general questions will need resolution through additional research in various areas, the present data base provides enough inferential power to suggest alternatives to the reconstructions of Northern Rocky Mountain prehistory as suggested by Husted (the Western Macro-Tradition) and Swanson (the Bitterroot Pattern).
Instability of Isolated Spectrum for W-shaped Maps

description: In this note we consider $W$-shaped map $W_0=W_{s_1,s_2}$ with $\frac {1}{s_1}+\frac {1}{s_2}=1$ and show that eigenvalue 1 is not stable. We do this in a constructive way. For each perturbing map $W_a$ we show the existence of the "second" eigenvalue $λ_a$, such that $λ_a\to 1$, as $a\to 0$, which proves instability of isolated spectrum of $W_0$. At the same time, the existence of second eigenvalues close to 1 causes the maps $W_a$ behave in a metastable way. They have two almost invariant sets and the system spends long periods of consecutive iterations in each of them with infrequent jumps from one to the other.
