A new type of magnet array for planar motor
Creators: name: Chen, Rui
Publisher: name: University of British Columbia
Year: 2017

description: Non-contact 6-DOF planar motors are playing more and more important roles in high precision machine tools, such as photolithography machines in semiconductor industry. Among existing planar motor designs, magnetically levitated planar motors with moving magnet have the potential to greatly improve the performance of motion stages by eliminating the force disturbance from umbilical cables and hoses that supply electricity and cooling water to motion stages, and can be easily extended to multiple-stage application. However, moving magnet planar motors suffer from intrinsic high-order force ripples that are generated by the interaction between stator coils and magnetic field harmonic components from magnet arrays. This thesis presents the design, analysis and experimental results of a novel magnet array for planar motor application, termed as M-Magnet array. An M-Magnet array consists of four identical magnet pieces per spatial period. Each magnet piece has a magnetization axis in 45 degree direction relative to its side surfaces, instead of 0 or 90 degree magnetization pieces used in conventional Halbach arrays. Previous symmetric magnet array contains 5 magnet pieces at each spatial period with the two edge pieces having half width of inner magnet pieces. The new M-magnet array design allows a symmetric magnet array made of 4 identical pieces. In addition, M-Magnet array design has the scalability to be extended to various sizes of mover with only one type of magnets, which makes the manufacturing of movers more cost effective. This thesis develops 3D analytical models to investigate the actuating force and torque generation of magnet arrays, and its sensitivity to manufacturing tolerances. A novel hybrid array design based on M-Magnet array is presented which can attenuate 6th force ripple by a factor of 100 without sacrifice of force constant of the planar motor compared to existing array splitting solution. The new M-Magnet array and hybrid array designs are analyzed via 2D and 3D models. An M-Magnet array is fabricated and experimentally tested at two distances from the magnet array bottom plane. The experimental results match the calculation results from 3D analytical models within 3% deviation, which confirms the validity of the 3D models.

Investigating the hepatitis C virus and dengue virus interactions with host lipid pathways : from circulating human microRNAs to lipid modulating agents
Creators: name: Hyrina, Anastasia
Publisher: name: University of British Columbia
Year: 2017

description: Cholesterol and lipid levels are maintained through tightly controlled and complex feedback mechanisms that involve regulation of major metabolic genes. Dysregulation of cellular or plasma lipid levels can lead to a wide range of pathologies, including hyperlipidemia, atherosclerosis and other disorders. A number of viruses, including important human viruses of the Flaviviridae family such as hepatitis C virus (HCV) and dengue virus (DENV), utilize and modulate host lipids to support their lifecycles, and the resulting changes in lipid metabolism may contribute to virus-associated pathologies. The overall aim of this thesis was to determine the role of key regulators of host lipid homeostasis, including microRNAs (miR-122, miR-24 and miR-223) and proprotein convertases (SKI-1/S1P and PCSK9) during viral infection and virus-associated disease. To address this aim, we first examined the molecular interplay between three circulating microRNAs known to act as regulators of lipid homeostasis. The data we present in Chapter 2 shows that specific signatures of the three microRNAs were associated with different treatment outcomes in patients with chronic hepatitis C (CHC), indicating that these microRNAs correlate with HCV infection. We then tested the hypothesis that enzymatic regulators of lipid metabolism could also indicate HCV infection, and in Chapter 3 we show that PCSK9 levels were significantly upregulated in patients who achieved a treatment-based viral cure but not in relapsers. These data indicate that changes in PCSK9 concentrations may have an important role in both HCV infection and in host lipid metabolism. In Chapter 4, we tested whether reducing the abundance of lipid droplets via inhibition of SKI-1/S1P with a small molecule PF-429242 suppresses DENV infection. The inhibitor blocked SKI-1/S1P-mediated accumulation of lipid droplets in hepatoma cells and reduced DENV infection, identifying SKI-1/S1P as a potential target for indirect-acting anti-DENV agents. This study on modulators of lipid metabolism during HCV and DENV infections provides new insights into the complex host-virus interactions that associate with virally-induced disease. We hope that our data lay the foundation for understanding disease pathogenesis and support the development of future strategies for Flaviviridae - associated diseases.

description: Synchrony is one of the most common dynamical states emerging on networks. The speed of convergence towards synchrony provides a fundamental collective time scale for synchronizing systems. Here we study the asymptotic synchronization times for directed networks with topologies ranging from completely ordered, grid-like, to completely disordered, random, including intermediate, partially disordered topologies. We extend the approach of Master Stability Functions to quantify synchronization times. We find that the synchronization times strongly and systematically depend on the network topology. In particular, at fixed in-degree, stronger topological randomness induces faster synchronization, whereas at fixed path length, synchronization is slowest for intermediate randomness in the small-world regime. Randomly rewiring real-world neural, social and transport networks confirms this picture.

description: We show that when N>>1 the geometric entanglement measure of general N-qubit W states, except maximally entangled W states, is a one-variable function and depends only on the Bloch vector with the minimal z component. Hence one can prepare a W state with the required maximal product overlap by altering the Bloch vector of a single qubit. Next we compute analytically the geometric measure of large-scale W states by describing these systems in terms of very few parameters. The final formula relates two quantities, namely the maximal product overlap and the Bloch vector, that can be easily estimated in experiments.

description: We present the first analytical superposition of a charged black hole with an annular disk of extremal dust. In order to obtain the solutions, we first solve the Einstein-Maxwell field equations for sources that represent disk-like configurations of matter in confomastatic spacetimes by assuming a functional dependence among the metric function, the electric potential and an auxiliary function,which is taken as a solution of the Laplace equation. We then employ the Lord Kelvin Inversion Method applied to models of finite extension in order to obtain annular disks. The structures obtained extend to infinity, but their total masses are finite and all the energy conditions are satisfied. Finally, we observe that the extremal Reissner-Nordström black hole can be embedded into the center of the disks by adding a boundary term in the inversion.

Investigating the molecular architecture of yeast histone acetyltransferase complexes
Creators: name: Setiaputra, Dheva
Publisher: name: University of British Columbia
Year: 2018

description: Post-translational modification of histones, such as the addition of acetyl groups, is a major regulatory mechanism for gene expression. Histone acetylation is catalyzed by highly conserved lysine acetyltransferase (KAT) enzymes that are often part of large, modular, and multifunctional complexes. Despite their fundamental importance, the reasons behind the tendency of these enzymes to form large complexes remain unclear. We investigated the organization of these complexes by elucidating the molecular architecture of three yeast KAT complexes: Spt-Ada-Gcn5 Acetyltransferase (SAGA), nucleosomal acetyltransferase of histone H4 (NuA4), and Elongator. The yeast SAGA complex is the largest KAT complex in yeast, and activates the expression of many stress response genes. Mutations of its human homologues have been implicated in spinocerebellar ataxia and oncogenesis. Using single particle electron microscopy and crosslinking coupled to mass spectrometry, we show that the catalytic module of SAGA resides within a highly flexible tail adjacent to numerous chromatin-binding subunits. We propose that the flexible SAGA tail is the nucleosome-interacting surface, and its plasticity serves to accommodate the various configurations of the chromatin substrate. NuA4 is another KAT complex whose catalytic subunit, Esa1, is the only essential KAT in yeast. NuA4 has highly conserved roles in the expression of housekeeping genes and the DNA damage repair pathway. Its subunits organize into modules that act independently of the complex. We show that these moonlighting modules form distinct globular structures that are peripherally associated with NuA4, which likely facilitates their dynamic nature. Similar to SAGA, NuA4 subunits that bind chromatin surrounds its catalytic subunit, possibly positioning its substrate nucleosome for efficient acetylation. Yeast Elongator, consisting of two copies each of six unique subunits, was initially characterized as a component of the elongating RNA polymerase II holoenzyme with histone acetyltransferase activity. However, further research has revealed a prominent role for the complex in modifying the wobble base pair of tRNAs. We generated the first three-dimensional reconstruction of Elongator and show that it organizes asymmetrically, with the two copies of its catalytic subunit residing in very different environments. Our structural investigations represent the first steps towards understanding the molecular mechanisms of these enigmatic complexes.

The numerical results indicate the $p\bar{p}$, $Σ\barΣ$ and $Ξ\barΞ$ bound states maybe exist, and the $X(1835)$ can be tentatively identified as the $p\bar{p}$ bound state.

description: Results from the Cassini-Huygens space mission at Enceladus revealed a substantial inventory of organic species embedded in plume and E ring ice grains originating from a global subsurface and putative habitable ocean. Compositional analysis by the Cosmic Dust Analyzer indicated the presence of aromatic species and constrained some structural features, although their exact nature remains unclear. As indicated by many studies, among other organic species, low-mass aromatics likely played a role in the emergence of life on Earth and may be linked to potential prebiotic or biogenic chemistry on icy moons. Here, we study the behavior of single-ringed aromatic compounds—benzoic acid and two isomeric derivatives, 2,3-dihydroxybenzoic acid and 2,5-dihydroxybenzoic acid—using Laser-Induced Liquid Beam Ion Desorption (LILBID), an analogue setup to simulate the impact ionization mass spectra of ice grains in space. These compounds share common structural features but also exhibit differences in functional groups and substituent positions. We investigate the fragmentation behavior and spectral appearance of each molecule over three simulated impact velocities, in both positive and negative ion modes. Parent compounds can be distinguished easily from their derivatives due to various spectral differences, including the (de)protonated molecular ion peaks appearing at different m/z values. We conclude that distinction between structural isomers in LILBID is more challenging, but some insights can be revealed by considering intermolecular bonding regimes. This work will guide future investigations into elucidating the composition of isomeric biosignatures in ice grains, relevant for future space missions to Enceladus and Europa

description: We construct heterotic standard models by compactifying on smooth Calabi-Yau three-folds in the presence of purely Abelian internal gauge fields. A systematic search over complete intersection Calabi-Yau manifolds with less than six Kahler parameters leads to over 200 such models which we present. Each of these models has precisely the matter spectrum of the MSSM, at least one pair of Higgs doublets, the standard model gauge group and no exotics. For about 100 of these models there are, naively, four additional U(1) symmetries, however these are Green-Schwarz anomalous and, hence, massive. In the remaining cases, three U(1) symmetries are anomalous while the fourth, massless one can be spontaneously broken by singlet vacuum expectation values. The presence of additional global U(1) symmetries, together with the possibility of switching on singlet vacuum expectation values, leads to a rich phenomenology which is illustrated for a particular example. Our database of standard models, which can be further enlarged by simply extending the computer-based search, allows for a detailed and systematic phenomenological analysis of string standard models, covering issues such as the structure of Yukawa couplings, R-parity violation, proton stability and neutrino masses.

description: Any dielectric lens has a finite closed boundary and therefore is, in fact, an open dielectric resonator capable of supporting resonant modes whose Q-factor depends of the lens parameters (size, shape, and material). The hemielliptic lens, that is an essential building block of many mm-wave and THz antennas, is not an exception: it supports the so-called halfbowtie (HBT) resonances that can strongly affect performance of such antennas. In this paper we illustrate the interplay between the optical and modal features in the electromagnetic behaviour of hemielliptic lenses and highlight the drastic influence of the HBT resonances on radiation characteristics of lens antennas. We also discuss the difficulties associated with accurate description of the resonant phenomena in compact-size hemielliptic lenses with conventional techniques and provide recommendations on how to minimize the parasitic impact of HBT resonances on the antenna performance.

description: Subdwarf B (sdB) stars are hot, sub-luminous stars which are thought to be core-helium burning with thin hydrogen envelopes. The mechanism by which these stars lose their envelopes has been controversial but it has been argued that binary star interaction is the main cause. Over the past decade we have conducted a radial velocity study of a large sample of sdB stars, and have shown that a significant fraction of the field sdB population exists in binary systems. In 2002 and 2003 we published 23 new binary sdB stars and the definitions of their orbits. Here we present the continuation of this project. We give the binary parameters for 28 systems, 18 of which are new. We present also our radial velocity measurements of a further 108 sdBs. Of these, 88 show no significant evidence of orbital motion. The remaining 20 do show radial velocity variations, and so are good candidates for further study. Based on these results, our best estimate for the binary fraction in the sdB population is 46 - 56 per cent. This is a lower bound since the radial velocity variations of very long period systems would be difficult to detect over the baseline of our programme, and for some sources we have only a small number of measurements.

Effect of human fecal extracts on Campylobacter jejuni gene expression and pathogenesis
Creators: name: Liu, Martha
Publisher: name: University of British Columbia
Year: 2017

description: Campylobacter jejuni (C. jejuni), a zoonotic commensal that is pathogenic in humans, is one of the most common bacterial causes of food borne illness worldwide. To assess how C. jejuni responds to the metabolome of a commensal host (chickens) versus a disease susceptible host (humans), differences in gene expression was evaluated after C. jejuni exposure to cell-free extracts prepared from chicken cecal and human fecal matter. RNA sequencing identified 12 genes with >2 fold difference in expression when C. jejuni was exposed to human fecal extracts in comparison to chicken cecal extract. 10 of these genes appear to be involved in iron uptake, of which 7 (CJJ81176_1649 to 1655) were part of one iron uptake system. This system likely acquires chelated iron not recognized by other iron uptake systems since measurement of total iron content showed that human fecal extracts contained ~4.5X more iron than chicken cecal extract. Homologs of the CJJ81176_1649 to 1655 proteins were identified in alpha, epsilon and gamma proteobacteria, and mapping of the homologous proteins to representative bacterial genomes showed that gene order and operon structure were well preserved for homologs of the entire CJJ81176_1649 to 1655 gene cluster. The widespread prevalence of the entire gene cluster putatively suggests that the proteins encoded by CJJ81176_1649 to 1655 represent a complete iron uptake system. The CJJ81176_1649 iron transporter and the p19 (CJJ81176_1650) periplasmic iron binding proteins have been previously characterized, but the downstream genes have not been directly studied and functions are predicted by homology. Deletion of CJJ81176_1651 to 1655 and the overlapping CJJ81176_1656 gene in this study rendered C. jejuni more sensitive to iron depletion than wild type, comparable to that of the p19 mutant. Furthermore, this iron uptake system appears to be involved in adaptation to low pH, but at the cost of increased sensitivity to hydrogen peroxide stress. This work demonstrates that the heretofore understudied, but widely conserved, CJJ81176_1649 to 1656 iron uptake system may be involved in host colonization by uptake of chelated iron more abundantly present in the human intestinal environment than that of the chicken cecum.

description: Online Social Networks (OSNs) are a cutting edge topic. Almost everybody --users, marketers, brands, companies, and researchers-- is approaching OSNs to better understand them and take advantage of their benefits. Maybe one of the key concepts underlying OSNs is that of influence which is highly related, although not entirely identical, to those of popularity and centrality. Influence is, according to Merriam-Webster, "the capacity of causing an effect in indirect or intangible ways". Hence, in the context of OSNs, it has been proposed to analyze the clicks received by promoted URLs in order to check for any positive correlation between the number of visits and different "influence" scores. Such an evaluation methodology is used in this paper to compare a number of those techniques with a new method firstly described here. That new method is a simple and rather elegant solution which tackles with influence in OSNs by applying a physical metaphor.

description: We present high-resolution CARMA 230 GHz continuum imaging of nine deeply embedded protostars in the Serpens Molecular Cloud, including six of the nine known Class 0 protostars in Serpens. This work is part of a program to characterize disk and envelope properties for a complete sample of Class 0 protostars in nearby low-mass star forming regions. Here we present CARMA maps and visibility amplitudes as a function of uv-distance for the Serpens sample. Observations are made in the B, C, D, and E antenna configurations, with B configuration observations utilizing the CARMA Paired Antenna Calibration System. Combining data from multiple configurations provides excellent uv-coverage (4-500 klam), allowing us to trace spatial scales from 1e2 to 1e4 AU. We find evidence for compact disk components in all of the observed Class 0 protostars, suggesting that disks form at very early times (t<0.2 Myr) in Serpens. We make a first estimate of disk masses using the flux at 50 klam, where the contribution from the envelope should be negligible, assuming an unresolved disk. The resulting disk masses range from 0.04 Msun to 1.7 Msun, with a mean of approximately 0.2 Msun. Our high resolution maps are also sensitive to binary or multiple sources with separations > 250 AU, but significant evidence of multiplicity on scales <2000 AU is seen in only one source.

description: We study various probability measures for eternal inflation by applying their regularization prescriptions to models where inflation is not eternal. For simplicity we work with a toy model describing inflation that can interpolate between eternal and non-eternal inflation by continuous variation of a parameter. We investigate whether the predictions of four different measures (proper time, scale factor cutoff, stationary and causal {diamond}) change continuously with the change of this parameter. We will show that {only} for the stationary measure the predictions change continuously. For the proper-time and the scale factor cutoff, the predictions are strongly discontinuous. For the causal diamond measure, the predictions are continuous only if the stage of the slow-roll inflation is sufficiently long.

Studies on immune escape mechanism in cancer
Creators: name: Saranchova, Iryna
Publisher: name: University of British Columbia
Year: 2020

description: Metastatic cancer is the leading cause of death in Canada. The personalized medical framework considers each patient’s genetic profile as a background to develop a specific treatment approach. Due to the success of early diagnostics, the mutational landscape of a tumour is mainly based on the sequencing data collected from early resected primary tumours, which do not necessarily reflect the mutational heterogeneity of the metastatic form of the disease and/or local recurrences underestimating tumour adaptational variations, challenging biomarker development and hindering therapeutic strategies of personalized medicine. This study has been designed to define the changes in metastatic potential of a developing tumour highlighting the immunological tumour properties, as one of emerging cancer hallmark. Microarray profiling of two separate paired cell lines of murine lung and prostate carcinomas allowed the detection of IFI44 and IL-33 as possible regulators of immunological properties within tumours. Significant down-regulation of these genes allows cancer cells with high metastatic potential to acquire capabilities to avoid destruction by the immune system via suppression of MHC-I expression. The immune-evasive phenotype allows tumour to obtain biological advantages resulting in the evasion of eradication by the immune system, which is a significant barrier for tumour growth and progression. Further study found that the overexpression of these selected genes reverses the antigen presentation deficiency in murine metastatic lung carcinoma and makes the tumour recognizable to the immune system. A parallel human study demonstrated that the expression of IL-33 is also co-regulated with HLA-I levels in human prostate cancer. Moreover, IL-33 by itself may be used as an immune prognostic biomarker for recurrence and survival in human prostate and kidney renal clear cell carcinomas. This new link in cancer biology allowed for the development a novel immunotherapeutic strategy for cancer-free survival via IL-33/ILC2 axis and the use of adoptively-transferred ILC2s. Testing this strategy on ILC2-deficient animals and animals that received ILC2s via adoptive transfer showed the importance of IL-33 and ILC2s in reducing tumour growth rate and metastatic spread to distal organs. Collectively, this thesis demonstrates a new mechanism for tumour immune escape and suggests a novel immunotherapeutic approach for anti-cancer treatment.
$d+id$ Holographic Superconductors

description: A holographic model of $d+id$ superconductors based on the action proposed by Benini, Herzog, and Yarom [arXiv:1006.0731] is studied. This model has a charged spin two field in an AdS black hole spacetime. Working in the probe limit, the normalizable solution of the spin two field in the bulk gives rise to a $d+id$ superconducting order parameter at the boundary of the AdS. We calculate the fermion spectral function in this\ superconducting background and confirm the existence of fermi arcs for non-vanishing Majorana couplings. By changing the relative strength $γ$ of the $d$ and $id$ condensations, the position and the size of the fermi arcs are changed. When $γ=1$, the spectrum becomes isotropic and the spectral function is s-wave like. By changing the fermion mass, the fermi momentum is changed. We also calculate the conductivity for these holographic $d+id$ superconductors where time reversal symmetry has been broken spontaneously. A non-vanishing Hall conductivity is obtained even without an external magnetic field.

Precise absolute astrometry from the VLBA imaging and polarimetry survey at 5 GHz

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We present in this paper accurate positions of 857 sources derived from the astrometric analysis of 16 eleven-hour experiments from the Very Long Baseline Array imaging and polarimetry survey at 5 GHz (VIPS). Among observed sources, positions of 430 objects were not determined before at a milliarcsecond level of accuracy. For 95% of the sources the uncertainty of their positions range from 0.3 to 0.9 mas, with the median value of 0.5 mas. This estimate of accuracy is substantiated by the comparison of positions of 386 sources that were previously observed in astrometric programs simultaneously at 2.3/8.6 GHz. Surprisingly, the ionosphere contribution to group delay was adequately modeled with the use of the total electron contents maps derived from GPS observations and only marginally affected estimates of source coordinates.

description: In this thesis, we investigate three specific policy and regulatory issues from the field of law and economics by means of economic experimentation. We first analyze the effects of excluding cartel ringleaders from corporate leniency programs. Then, we evaluate pricing behavior under a new kind of price regulation scheme along the lines of the 'Austrian rule'. Finally, we introduce an explicit role for a strategically acting authority and investigate decision-making under ambiguity.

Percolation of Color Sources and the determination of the Equation of State of the Quark-Gluon Plasma (QGP) produced in central Au-Au collisions at \sqrt S_{NN}= 200 GeV

description: The Color String Percolation Model (CSPM) is used to determine the equation of state (EOS) of the QGP produced in central Au-Au collisions at $\sqrt{s_{NN}}$ = 200 A GeV using STAR data at RHIC. When the initial density of interacting colored strings exceeds the 2D percolation threshold a cluster is formed, which defines the onset of color deconfinement. These interactions also produce fluctuations in the string tension which transforms the Schwinger particle (gluon) production mechanism into a maximum entropy thermal distribution. The single string tension is determined by identifying the known value of the universal hadron limiting temperature $T_{c}$ = 167.7 $\pm$ 2.6 MeV with the CSPM percolation temperature at the critical threshold $ξ_{c}$ =1.2. At mid-rapidity the initial Bjorken energy density and the initial temperature determine the number of degrees of freedom consistent with the formation of a $\sim$ 2+1 flavor QGP. An analytic expression for the equation of state, the sound velocity $C_{s}^{2}(ξ)$ is obtained in CSPM. The CSPM $C_{s}^{2}(ξ)$ and the bulk thermodynamic values $\varepsilon /T^{4}$ and $s /T^{3}$ are in excellent agreement in the phase transition region with recent lattice QCD simulations (LQCD) by the HotQCD Collaboration.
