The generation of acetylcholine-induced asynchronous Ca²⁺ waves and their role in airway smooth muscle
Creators: name: Dai, Jiazhen Minnie
Publisher: name: University of British Columbia
Year: 2010

description: Agonist-stimulated repetitive asynchronous Ca²⁺ waves (ACW) have emerged as ubiquitous Ca²⁺ signals in airway smooth muscle cells. Even though the role of this type of Ca²⁺ signal in airway smooth muscle (ASM) has yet to be defined, it is likely that ACW are involved in the regulation of airway constriction due to the significance of Ca²⁺ in ASM contraction. This thesis focuses on: (1) the primary function of ACW and (2) the signaling pathway(s) underlying agonist-induced ACW in intact ASM. Employing confocal imaging of Ca²⁺-sensitive dyes, we found that ACh elicits recurring intracellular Ca²⁺ waves in cells of the intact porcine tracheal and more importantly human bronchial muscle bundle. These Ca²⁺ waves were not synchronized between neighboring cells. Simultaneous measurement of intracellular Ca²⁺ concentration ([Ca²⁺]i ) and isometric contraction indicates that induction of these ACW was temporally associated with development of force by the muscle bundles. By comparing the concentration dependence of force generation and the parameters characterizing ACW, we found that the concentration-dependent increase in ACh-induced force development by the ASM bundle is achieved by differential recruitment of cells to initiate Ca²⁺ waves followed by enhancement in the frequency of ACW and elevation of interspike [Ca²⁺ ]i once the cells are recruited. Furthermore, pharmacological characterization of the mechanism of ACh-induced ACW revealed that they are a result of repetitive cycles of sarcoplasmic reticulum (SR) Ca²⁺ release via ryanodine-sensitive Ca²⁺ release channels followed by refilling of the SR via sarco(endo)plasmic reticulum Ca²⁺ ATPase. Plasmalemmal Ca²⁺ entry via the reverse-mode Na⁺/Ca²⁺ exchange coupled with the non-selective cation permeable receptor-operated channels/store-operated channels, and to a lesser extent via the L-type voltage-gated Ca²⁺ channels is involved in replenishing the SR and supporting the ongoing ACW. Given the significance of ASM in the pathogenesis of airway diseases such as asthma, these findings provide insights into the regulation of ASM contraction and potential therapeutic targets for the management of these diseases.

description: Certain systems, such as amphiphile solutions or diblock copolymer melts, may assemble into structures called ``mesophases'', with properties intermediate between those of a solid and a liquid. These mesophases can be of very regular structure, but may contain defects and grain boundaries. Different visualization techniques such as volume rendering or isosurfacing of fluid density distributions allow the human eye to detect and track defects in liquid crystals because humans are easily capable of finding imperfections in repetitive spatial structures. However, manual data analysis becomes too time consuming and algorithmic approaches are needed when there are large amounts of data. We present and compare two different approaches we have developed to study defects in gyroid mesophases of amphiphilic ternary fluids. While the first method is based on a pattern recognition algorithm, the second uses the particular structural properties of gyroid mesophases to detect defects.

description: In this paper we study the single longitudinal spin asymmetry $A_{UL}^{\sin(ϕ_h-ϕ_R)}$ of dihadron production in semi-inclusive deep inelastic scattering (SIDIS) via helicity-dependent dihadron fragmentation function (DiFF), which describes the correlation of the longitudinal polarization of a fragmenting quark with the transverse momenta of the produced hadron pair. Recently experimental searching for this azimuthal asymmetry in dihadron SIDIS by the COMPASS Collaboration yielded a very small signal. Here we calculate this unknown T-odd DiFF $G_1^\perp$ using a spectator model to access the asymmetry and clarify why the signal is very small. The transverse momentum dependent (TMD) factorization method, in which the transverse momentum of the final state hadron pair leaves unintegrated, has been applied. We estimate the $\sin(ϕ_h-ϕ_R)$ asymmetry at the kinematics of COMPASS experiments and compare with the data. What's more, the predictions on the same asymmetry are also made at the Electron Ion Collider (EIC).

description: According to the covariant open superstring description of D-branes in the AdS$_4 \times \mathbf{CP}^3$ background, 1/2-BPS D2-branes are purely instantonic. Based on this and by taking the eleven dimensional viewpoint, we identify the 1/2-BPS instantonic M2-brane configurations in the AdS$_4 \times$ S$^7 / \mathbf{Z}_k$ background, which reduces to the AdS$_4 \times \mathbf{CP}^3$ under the large $k$ limit, and evaluate their action values. We also consider the previously known 1/2-BPS instantonic objects in ten dimensions from the M2-brane viewpoint to compare with our results.

description: Recent experiments reported gate-induced superconductivity in the monolayer 1T$'$-WTe$_2$ which is a two-dimensional topological insulator in its normal state [1, 2]. The in-plane upper critical field $B_{c2}$ is found to exceed the conventional Pauli paramagnetic limit $B_p$ by 1-3 times. The enhancement cannot be explained by conventional spin-orbit coupling which vanishes due to inversion symmetry. In this work, we unveil some distinctive superconducting properties of centrosymmetric 1T$'$-WTe$_2$ which arise from the coupling of spin, momentum and band parity degrees of freedom. As a result of this spin-orbit-parity coupling: (i) there is a first-order superconductor-metal transition at $B_{c2}$ much higher than the Pauli paramagnetic limit $B_p$, (ii) spin-susceptibility is anisotropic with respect to in-plane directions and results in anisotropic $B_{c2}$ and (iii) the $B_{c2}$ exhibits a strong gate dependence as the spin-orbit-parity coupling is significant only near the topological band crossing points. The importance of SOPC on the topologically nontrivial inter-orbital pairing phase is also discussed. Our theory generally applies to centrosymmetric materials with topological band inversions.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

Regulation of slow inactivation in Kv1.5 by the turret
Creators: name: Eduljee, Cyrus
Publisher: name: University of British Columbia
Year: 2010

description: In Kv channels, slow, P/C-type, inactivation is thought to eliminate ionic current via a concerted structural rearrangement of the outer pore mouth. However, little is known regarding the contributions of other pore regions to the regulation of slow inactivation. Our experiments now indicate that the turret region of Kv1.5 can be an important determinant of slow inactivation. Application of extracellular protons, or divalent cations such as Zn²⁺ or Ni²⁺, was found to reduce the peak current amplitude, and with protons, also increase the rate of depolarization-induced inactivation. These effects were alleviated by the substitution of residue H463 in the turret with a glutamine, indicating that the interaction of this turret residue with extracellular ligands facilitated the inhibition of current. Based on macroscopic, unitary and gating current analyses, we have attributed the effects of protonation and divalent cations to an enhancement of depolarization-induced and closed-state inactivation. These findings provide strong evidence that the turret region contributes to the regulation of slow inactivation in Kv1.5. To determine which properties of position 463 were important in modulating inactivation, various side chain substitutions of this position were examined and several were found to mimic the effects of proton or divalent cation binding. However, the properties of the substituted side chains were not well correlated with the effects on channel function, and it appeared that the turret and inactivation gate did not interact strictly via an electrostatic interaction, as suggested by others. A SCAM analysis was subsequently conducted by substituting cysteine residues into each turret position to determine which regions of the turret were important for regulating slow inactivation. Modification of substituted cysteine residues in the distal turret by MTS reagents produced an inhibition that could also be related to an enhancement of slow inactivation and demonstrated that position 463 was contained within a distinct locus of turret residues that could influence slow inactivation. These results indicate that in Kv1.5 a specific region of the turret modulates the state of the inactivation gate and provide constraints on the mechanisms of interaction between the turret and inactivation gate.

description: Heavy axion-like particles (ALPs), with masses $m_a \gtrsim 100$ keV, coupled with photons, would be copiously produced in a supernova (SN) core via Primakoff process and photon coalescence. Using a state-of-the-art SN model, we revisit the energy-loss SN 1987A bounds on axion-photon coupling. Moreover, we point out that heavy ALPs with masses $m_a \gtrsim 100$ MeV and axion-photon coupling $g_{aγ} \gtrsim 4 \times 10^{-9}$ GeV$^{-1}$ would decay into photons behind the shock-wave producing a possible enhancement in the energy deposition that would boost the SN shock revival.

description: Magnetic field induced multiple non-Dirac nodal-lines are found to emerge in the triplet dispersion bands of a frustrated spin-1/2 antiferromagnetic model on the CaVO lattice. Plaquette and bond operator formalisms have been employed to obtain the triplet plaquette and bond excitations for two different parameter regimes in the presence of nearest and next-nearest-neighbor Heisenberg interactions based on the plaquette-resonating-valence-bond and dimerized ground states, respectively. In the absence of magnetic field a pair of six-fold degenerate nodal-loops with distinct topological feature is noted in the plaquette excitations. They are found to split into three pairs of two-fold degenerate nodal-loops in the presence of magnetic field. In the other parameter regime, system hosts two-fold degenerate multiple nodal-lines with a variety of shapes in the triplon dispersion bands in the presence of magnetic field. Ground state energy and spin gap have been determined additionally for the two regimes. Those nodal-lines are expected to be detectable in neutron scattering experiment on the frustrated antiferromagnet, CaV$_4$O$_9$.

description: The differential cross section and charge asymmetry for inclusive W boson production at $\sqrt{s} =$ 13 TeV is measured for the two transverse polarization states as a function of the W boson absolute rapidity. The measurement uses events in which a W boson decays to a neutrino and either a muon or an electron. The data sample of proton-proton collisions recorded with the CMS detector at the LHC in 2016 corresponds to an integrated luminosity of 35.9 fb$^{-1}$. The differential cross section and its value normalized to the total inclusive W boson production cross section are measured over the rapidity range $|y_\mathrm{W}|$ $\lt$ 2.5. In addition to the total fiducial cross section, the W boson double-differential cross section, d$^2σ$/d$p^\ell_\mathrm{T}$d$|η|$ and the charge asymmetry are measured as functions of the charged lepton transverse momentum and pseudorapidity. The precision of these measurements is used to constrain the parton distribution functions of the proton using the next-to-leading order NNPDF3.0 set.

Publisher: name: University of British Columbia
Year: 2010

description: The study was conducted to propose design solutions and alternatives that could be applied on community design and planning to support the needs of the elderly for their physical activity (walking) and social interaction within the built environment. Cadboro Bay community in Regional District of Saanich, BC was particularly selected for the study considering its large population of the elderly and their increased demand for creating an accessible, safe, and pedestrian friendly community. By reviewing relevant literature and projects for the needs of the elderly for their physical activity and social interaction, and assessing the current condition of built environment and its relationship to physical activity of the elderly within the community context, design principles were proposed and the solutions based on 13 key principles were implemented in three scales of community design for Cadboro Bay: land use pattern, street and transportation network, and design characteristics. These proposed design solutions were also tested and evaluated by walking distance analysis, the assessment of Pedestrian LOS, and visual simulation of walking experience comparing the current condition and the proposed plan. It is found that the adherence to the principles resulted in improving the built environment to accommodate the needs of the elderly for their physical activity and social interaction.

description: Background: WHO hepatitis B guidelines recommend testing all new HIV patients, treating them accordingly or providing immunization. At the Infectious Diseases Institute (IDI) following an audit done in 2012, only 46% patients had been screened for hepatitis B with variable management plans therefore new internal guidelines were implemented. This study describes the uptake of hepatitis B screening and management of patients with hepatitis B and HIV con-infection after the implementation. Methods: Data included for all HIV positive patients in care at IDI by October 2015. Data are expressed as median with interquartile range (IQR) and percentages were compared using the chi square test. Statistical analysis was performed using STATA version 13. The IDI laboratory upper limit of normal for alanine aminotransferase (ALT) and aspartate aminotransferase (ASTs) was 40 IU/ml. Results: Number of hepatitis B screening tests increased from 800 by 2012 to 1400 in 2015. By 2015 8042/8604(93.5%) patients had been screened for hepatitis B. Overall hepatitis B positive were 359 (4.6%). 166 (81.4%) hepatitis B positives were switched to a tenofovir (TDF) containing regimen. Conclusion: Our study confirms the importance of screening for hepatitis B and of using ART regimens containing tenofovir in hepatitis B co-infected patients. Whilst our program has made improvements in care still 18.6% of patients with hepatitis B were not on tenofovir regimens, 98.1% had no hepatitis B viral loads done. Clinicians should recognize the potential for hepatitis B in HIV positive patients and the importance of early diagnosis and treatment to ensure optimal management of cases and follow up.

description: The dark energy in the Universe is described in the context of modified Friedmann equations as a fluid parameterized by the density of dark matter and undergoing an adiabatic expansion. This formulation is applied to the Cardassian model. Choosing then parameters consistent with the supernova observations, it gives a background expansion in which the cosmic temperature fluctuations are calculated. The resulting spectrum is quite similar to what is obtained in the standard concordance model. If the Cardassian fluid is interpreted as a new kind of interacting dark matter, its overdensities are driven into oscillations when the interaction energy is rising in importance. This does not occur in a description of the Cardassian fluctuations motivated by theories of modified gravity. There the energy of the underlying matter is also conserved, which requires appearance of effective shear stress in the late Universe. In both approaches that allow fluctuations the thermal power spectrum at large scales is much too strongly enhanced by the late integrated Sachs-Wolfe effect. With the interacting dark matter assumption, we conclude that the Cardassian model is ruled out by observations, expect in a small neighbourhood of the $Λ$CDM limit.

description: Using renormalization group and exact diagonalization of small clusters we investigate the ground state phase diagram of a two-dimensional extended Hubbard model with nearest-neighbor exchange interaction J, in addition to the local Coulomb repulsion U. The main instabilities are antiferromagnetism close to half-filling and d-wave superconductivity in the doped system. Our results suggest that the combined action of J and U interactions provide a remarkably efficient mechanism to enhance both d-wave superconducting and antiferromagnetic correlations.

description: This study aims to improve the performance and generalization capability of end-to-end autonomous driving with scene understanding leveraging deep learning and multimodal sensor fusion techniques. The designed end-to-end deep neural network takes as input the visual image and associated depth information in an early fusion level and outputs the pixel-wise semantic segmentation as scene understanding and vehicle control commands concurrently. The end-to-end deep learning-based autonomous driving model is tested in high-fidelity simulated urban driving conditions and compared with the benchmark of CoRL2017 and NoCrash. The testing results show that the proposed approach is of better performance and generalization ability, achieving a 100% success rate in static navigation tasks in both training and unobserved situations, as well as better success rates in other tasks than the prior models. A further ablation study shows that the model with the removal of multimodal sensor fusion or scene understanding pales in the new environment because of the false perception. The results verify that the performance of our model is improved by the synergy of multimodal sensor fusion with scene understanding subtask, demonstrating the feasibility and effectiveness of the developed deep neural network with multimodal sensor fusion.

description: (Abridged) We present high-resolution spectra of the interstellar NaI and CaII absorption lines for 3 early-type stars along the line-of-sight towards the Shajn 147 SNR. These are supplemented with far-UV aborption spectra of HD 36665 and HD 37318 recorded with the NASA FUSE satellite. The observations reveal intermediate-velocity (IV) absorption features at V_helio = +92 km/s towards HD 37318 and -65 & -52 km/s towards HD 36665. These IV components can be associated with the expansion of the SNR. The observations suggest that the IV component at +92 km/s towards HD 37318 is composed mainly of warm and ionized gas. The two IV components observed towards HD 36665 are likely composed of both neutral and ionized gas shells. Highly ionized gas was detected in the OVI (1032Å) absorption line at +40 km/s towards both stars. This hot gas component is characterized by a columnn density ratio (N(CIV)/N(OVI) < 0.27) consistent with that predicted by current models of evolved SNRs, but we cannot preclude its origin in the ISM. Column-density ratios have been derived for the IV gas components detected towards S147, as well as for fast-moving gas observed towards two other SNRs in order to gain some insight into the behavior of element abundances in the disturbed interstellar gas associated with these regions. In all cases except for Na and Ca, these elements appear to be present with near-solar abundance ratios. (Abridged)

title: On the Scope of Digital Vocabulary Trainers for Learning in Distance Education
Creators: name: Winchester, Susanne
Publisher: name: The Open University
Year: 2015

description: This study explores the use of digital vocabulary trainers (DVTs) for L1 (first/native language) - L2 (second/foreign language) paired associate vocabulary learning in the context of distance learning and where students are mature adult learners. The literature review approaches the topic from three different angles: firstly, what is involved in vocabulary learning in terms of memory processes, learning strategies and motivation to learn. Secondly, it was investigated how computer-assisted language learning (CALL) and in particular, use of DVTs, can support the learning of vocabulary and lastly, the role the specific learning context of distance education plays where vocabulary learning is concerned. To set the context, the study outlines the capabilities of different DVTs and how these are linked to theoretical frameworks, how distance learners engage with DVTs, to what extent vocabulary learning with and without DVTs differs and what students’ preferences for particular features of DVTs are. The research is based on a quasi-experimental study to explore the scope and limitations of DVTs used by adult distance learners at the Open University in the UK. A mix of methods was utilised, generating both quantitative and qualitative data. After participating in a trial use of DVT for beginners’ German, Open University language learners participated in a number of surveys investigating the way in which they engage with DVTs, whether there is any indication that the use of these tools improves performance and how students perceive DVTs as learning tools. Additional surveys investigated the general attitude of distance language students to DVTs, and focus groups were formed from students using DVTs for study. Data from these focus groups show that mechanisms typically employed in game playing (e.g. points, badges, leader boards) can have a positive effect on motivation for learning. It is therefore concluded that a review of current pedagogy may be useful and that new approaches to more integrated vocabulary training could have positive effects on language learners.

description: Neutron stars (NSs) are excellent natural laboratories to constrain gravity on strong field regime and nuclear matter in extreme conditions. Motivated by the recent discovery of a compact object with $2.59^{+0.08}_{-0.09} M_\odot$ in the binary merger GW190814, if this object was a NS, it serves as a strong constraint on the NS equation of state (EoS), ruling out several soft EoSs favored by GW170817 event. In this work, we revisit the question of the maximum mass of NSs considering a chameleon screening (thin-shell effect) on the NS mass-radius relation, where the microscopic physics inside the NS is given by realistic soft EoSs. We find that from appropriate and reasonable combination of modified gravity, rotation effects and realistic soft EoSs, that it is possible to achieve high masses and explain GW190814 secondary component, and in return also NSs like PSR J0740+6620 (the most NS massive confirmed to date). It is shown that gravity can play an important role in estimating maximum mass of NSs, and even with soft EoSs, it is possible to generate very high masses. Therefore, in this competition on the hydrostatic equilibrium between gravity and EoS, some soft EoSs, in principle, cannot be completely be ruled out without first taking into account gravitational effects.

title: Collisional and structural properties of water ice in planet-forming regions
Creators: name: Hill, Catherine
Publisher: name: The Open University
Year: 2015

description: With the number of detected exoplanets standing at close to 2000, it seems that planets are ubiquitous throughout the universe. However, the processes leading to their formation are not well understood. It is widely accepted that planets form by dust aggregation from the material of protoplanetary disks, with micron-sized particles sticking together by van der Waals forces and kilometre-sized particles sticking together due to gravity. The process of growth between millimetre and kilometre sizes is yet to be explained, despite decades of research studying the collisions of silicate dust particles which form the main component of protoplanetary dust. However, the water ice that is present in the outer regions of protoplanetary disks has so far received less consideration. In this thesis, the collisional and structural properties of ices analogous to those in planet-forming regions were studied experimentally. Low velocity collisions of millimetre and centimetre-sized crystalline ice particles (both pure water and ice composed of pure water and water containing 5% methanol or formic acid) were investigated using a dedicated experimental set up for use on board parabolic flights. The porosity and pore collapse of amorphous solid water (ASW) grown at a variety of temperatures was investigated using neutron scattering. The results presented in this thesis show that crystalline water ice particles do not stick at relevant collision velocities, casting doubt on their ability to enhance planet formation by particle adhesion. However, the results of the neutron scattering experiments suggest that ASW is likely to remain porous at temperatures below 121 K, which may increase the likelihood of particle sticking. Sticking may also be enhanced by ice restructuring during pore collapse. The results of the experiments growing ASW at temperatures below 77 K show that these ices have different porosities, but further work is needed to fully characterise this.

title: Planet Mercury: volatile release on a contracting world
Creators: name: Thomas, Rebecca
Publisher: name: The Open University
Year: 2015

description: This thesis investigates the geological processes by which materials containing high concentrations of volatile substances have been delivered to the surface of the planet Mercury throughout its history, despite global contraction, which could be expected to impede the replenishment of these materials from depth. With the aid of high-resolution data from the MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft, I perform detailed analyses of the two types of geological features most indicative of the action of volatiles at Mercury’s surface: flat-floored depressions known as ‘hollows’, and pits and deposits thought to be the products of explosive volcanism. For hollows, I seek to clarify the nature of the substance lost to form them and the mechanisms by which this has been introduced to, and lost from, the surface recently enough to explain their pristine appearance. I produce a global catalogue of hollows, study their local associations, and investigate their spectral character, finding evidence that they form primarily by sublimation of a moderately volatile substance, potentially a sulfide, from a specific low-reflectance substrate exhumed and exposed by meteorite impacts. To better understand explosive volcanism, I investigate its longevity and the processes promoting it at specific locations. Through identifying, dating and characterising proposed pyroclastic deposits and vents, I show that putative explosive volcanism was more long-lived than voluminous effusive eruptions, that its occurrence is tectonically controlled, and that its eruptive style indicates magma storage prior to eruption, at greater depths than on the more tectonically-neutral Moon. This indicates that, rather than precluding it, global contraction favoured volcanic explosivity by promoting magma storage during which volatiles could become concentrated in the magma. Furthermore, because processes concentrating volatiles have been important in the genesis of both hollows and explosive volcanism, their occurrence does not necessarily indicate a high planetary bulk volatile fraction.

description: Recent progress in understanding the emergence of confinement and other nonperturbative effects in the strong interaction vacuum is reviewed. Special emphasis is placed on the role of different types of collective infrared gluonic degrees of freedom in this respect. After a survey of complementary approaches, models of the QCD vacuum based on center vortices, Abelian magnetic monopoles and topological charge lumps such as instantons, merons and calorons are examined. Both the physical mechanisms governing these models as well as recent lattice studies of the respective degrees of freedom are reviewed.
