Subjects: Uncategorized

description: Objectives: This dissertation aimed to examine the influence of exposure to metal mixtures on growth-related outcomes in early life. Further, since evidence is limited with respect to the potential mediating role of exposure to metals in the relationship between dietary patterns and growth of children, we also evaluated such associations in this dissertation. Methods: In analyses of data from the Bangladesh Environmental Research in Children’s Health Cohort (BIRCH), we assessed the effects of exposure to seventeen metals, as measured in toenails, on growth of children aged 5-7 years by implementing principal component analyses (PCA), weighted quantile sum (WQS) regression, and Bayesian kernel machine regression (BKMR). Using the same data source, we further evaluated the potential mediating role of metal exposures in the association between dietary patterns and growth of Bangladeshi children. In analyses using the United States (U.S.) National Children’s Study (NCS), we performed PCA, WQS, ad BKMR to analyze 1st trimester blood concentrations of five metals and 3rd trimester urinary concentrations of twelve metals in relation to birth outcomes. Results: Analyses using BIRCH data suggested inverse joint effects of metal mixtures on growth-related outcomes; cadmium, uranium, and arsenic were identified as important metals driving these associations. In addition, copper and selenium were positively associated with growth of children. Four dietary patterns (varied diet, traditional diet, sweet and water diet, and protein diet) were identified and all of which showed positive impacts on growth of children. The positive associations of the varied diet with growth-related outcomes were significantly mediated by greater toenail selenium concentration. Analyses using NCS data found positive trends between exposure to 3rd trimester urinary metal mixtures and birth length and head circumference; arsenic was identified as the primary metal driving these associations. We also found negative joint effects of 1st trimester blood metal mixtures on birthweight and ponderal index. Couclusions: This dissertation work identified certain metals that may have detrimental or positive impacts on growth of infants and children with consideration of co-exposure patterns. We also identified certain dietary patterns that could be beneficial to children in Bangladesh regarding their linear growth.

description: The aim of the new generation of radio synthesis arrays such as LOFAR and SKA is to achieve much higher sensitivity, resolution and frequency coverage than what is available now, especially at low frequencies. To accomplish this goal, the accuracy of the calibration techniques used is of considerable importance. Moreover, since these telescopes produce huge amounts of data, speed of convergence of calibration is a major bottleneck. The errors in calibration are due to system noise (sky and instrumental) as well as the estimation errors introduced by the calibration technique itself, which we call solver noise. We define solver noise as the distance between the optimal solution (the true value of the unknowns, uncorrupted by the system noise) and the solution obtained by calibration. We present the Space Alternating Generalized Expectation Maximization (SAGE) calibration technique, which is a modification of the Expectation Maximization algorithm, and compare its performance with the traditional Least Squares calibration based on the level of solver noise introduced by each technique. For this purpose, we develop statistical methods that use the calibrated solutions to estimate the level of solver noise. The SAGE calibration algorithm yields very promising results both in terms of accuracy and speed of convergence. The comparison approaches we adopt introduce a new framework for assessing the performance of different calibration schemes.

description: As a compound preparation of traditional Chinese medicine, Jianwei Xiaoshi Tablets (JXT) is made from five Chinese herbs: Taizishen (Pseudostellariae Radix), Chenpi (Citri Reticulatae Pericarpium), Shanyao (Dioscoreae Rhizoma), Maiya (Hordei Fructus Germinatus) and Shanzha (Crataegi Fructus). It is mainly used to treat dyspepsia. However, the chemical composition of JXT is complex and unclear. In this study, ultra performance liquid chromatography-quadrupole-orbitrap-mass spectrometry and data post-processing technologies were used to analyse the samples of JXT. Firstly, the mass spectrometric information of the main components of five traditional Chinese herbs in JXT was summarised and a compound database was established. Then, the mass spectrometric data detected by the prepared samples was compared with the database. Finally, 93 chemical components were successfully identified, including 6 amino acids, 34 flavonoids, 18 alkaloids, 15 organic acids, 9 cyclic peptides and 11 other components, and the rapid classification and identification of chemical components of JXT were realised.

Scalable smart transducers network using Power-over-Ethernet : towards smarter, safer and more controllable buildings
Creators: name: Lobachev, Ivan
Publisher: name: University of British Columbia
Year: 2017

description: In the age of rapid technological advancement, many telecommunication applications are being integrated into our lives, including smart phones and Internet of Things (IoT). Smart buildings (and houses) use these technologies to reduce energy consumption and increase safety. The need for these buildings is growing as urbanization continues and resources dwindle. According to a report by the United Nations, by 2050 66% of the world’s population will live in cities. This will cause the size and number of megacities to expand drastically in the near future. Complex communication networks, controls and other services will allow us to build smart cities to manage and improve the public’s quality of life. The necessity of smart buildings and, eventually, cities, has stimulated growth of sensor networks for these purposes. This thesis discusses the research on creating a smart transducer network architecture concept that uses Power over Ethernet (PoE) as a method for transferring data and power over a single medium, together with principles of decentralized and remote computing for data processing. The concept prototype had its power supplied by a Cisco Catalyst 4507R+E switch and utilized cloud computing to provide an easily scalable and adaptable architecture, able to easily adapt to a wide array of applications and fit the demands of new trends or integration into other systems. The set-up was tested on RaspberryPi and BeagleBone microcontroller boards as sensor hubs, and used DigitalOcean as the cloud computing service of choice. The server in this implementation acts as user interface, front end, and as the console unit back end. The architecture has demonstrated the feasibility of the concept of uniting PoE and IoT to create a flexible architecture. The system has also demonstrated fast communication times, below 200ms, in a cross-continental setting and the ability to provide fast processing times of under 1s. This shows particular promise for the use of the architecture within the context of green and smart housing equipped with a low-cost sensor network, where local power is partially provided via renewable energy harvesting, and the majority of short-range power transmission is DC-centered.

description: Two new stigmastane steroids (1 and 2) were isolated from the methanol extract of the leaves of Vernonia glabra, together with seventeen known compounds (3–19) including one fatty acid, four triterpenoids, four steroids, one trinitropropanoyl glucoside, and seven flavonoids. The structures of compounds 1 and 2 were assigned based on their IR, NMR and MS data, and by comparison with literature values. The MeOH extract, its fractions and isolated compounds were subjected to in vitro antibacterial assay against two Gram-positive (Staphylococcus aureus ATCC25923 and Streptococcus pneumoniae ATCC49619) and two Gram-negative (Escherichia coli ATCC8739 and Klebsiella pneumoniae ATCC10031) bacteria, using broth microdilution method. The extract and fractions exhibited (16 ≤ MIC ≤ 512 μg/mL) antibacterial activities. The isolated and tested compounds were also active (16 ≤ MIC ≤ 128 μg/mL) against the four pathogenic bacteria, with compound 2 being the most active and E. coli, the most sensitive microorganism.

description: In galaxies like the Milky Way, cold (~ 10^4 K) gas ejected from the disc by stellar activity (the so-called galactic-fountain gas) is expected to interact with the virial-temperature (~ 10^6 K) gas of the corona. The associated transfer of momentum between cold and hot gas has important consequences for the dynamics of both gas phases. We quantify the effects of such an interaction using hydrodynamical simulations of cold clouds travelling through a hot medium at different relative velocities. Our main finding is that there is a velocity threshold between clouds and corona, of about 75 km/s, below which the hot gas ceases to absorb momentum from the cold clouds. It follows that in a disc galaxy like the Milky Way a static corona would be rapidly accelerated: the corona is expected to rotate and to lag, in the inner regions, by ~ 80-120 km/s with respect to the cold disc. We also show how the existence of this velocity threshold can explain the observed kinematics of the cold extra-planar gas.

description: The Karlsruhe Tritium Neutrino Experiment KATRIN aims to determine the mass of the electron antineutrino. A sensitivity of 200 meV requires a precise measurement of the endpoint region of the tritium beta-spectrum and dedicated analyses. For that purpose, detailed simulations of the source of KATRIN have been developed as well as specialized analysis routines. Measurements at a source test experiment revealed the thermal behaviour of the source.

description: In distributed quantum computation, small devices composed of a single or a few qubits are networker together to achieve a scalable machine. Typically there is an optically active matter qubit at each node, so that photons are exploited to achieve remote entanglement. However, in many systems the optically active states are unstable or poorly defined. We report a scheme to perform a high-fidelity entanglement operation even given severe instability. The protocol exploits the existence of optically excited states for phase acquisition without actually exciting those states; it functions with or without cavities and does not require number resolving detectors.

description: The largest known class of gravitational backgrounds with an exact string theoretical description is based on coset G/H CFTs and the corresponding gauged WZW models. These backgrounds generically lack isometries and are quite complicated. Thus the corresponding field equations seem impossible to solve and their use in physical applications becomes problematic. We develop a systematic general method enabling us to overcome this problem using group theory. The method is inspired by observations made in some elementary geometric coset and coset CFTs, but its full power is apparent in non-abelian cases. We analyze exhaustively the coset SU(2)xSU(2)/SU(2) and explicitly solve the scalar wave equation of the corresponding gravitational background. We also examine the high spin limit and derive the effective geometry that consistently captures the corresponding sector in the theory.

description: We study the morphology of luminous and massive galaxies at 0.32.35 selects a sub-sample of BOSS galaxies with 90% early-type morphology - more comparable to the earlier Luminous Red Galaxy (LRG) samples of SDSS-I/II. The remaining 10% of galaxies above this cut have a late-type morphology and may be analogous to the "passive spirals" found at lower redshift. We find that 23+/-4% of the early-type galaxies are unresolved multiple systems in the SDSS imaging. We estimate that at least 50% of these are real associations (not projection effects) and may represent a significant "dry merger" fraction. We study the SDSS pipeline sizes of BOSS galaxies which we find to be systematically larger (by 40%) than those measured from HST images, and provide a statistical correction for the difference. These details of the BOSS galaxies will help users of the data fine-tune their selection criteria, dependent on their science applications. For example, the main goal of BOSS is to measure the cosmic distance scale and expansion rate of the Universe to percent-level precision - a point where systematic effects due to the details of target selection may become important.

description: Two wild olive subspecies are fixed in this research: Olea europaea L.var. sylvestris and Olea europaea subsp. laperrinei despite its ecological value, the chemical composition of subsp. laperrinei oil remains unknown. The samples were harvested from the different geographical area. Gas Chromatography-Mass Spectrometry (GC-MS) and Gas Chromatography-flame-ionization detection (GC-FID) analysis of Olea europaea L. var. sylvestris allowed the identification of 29 compounds oil with Nonanal (11.82%), theaspiranea A (9.81%), 3-hexen-1-ol,benzoate(9.31%) as a major constituents, while in the subspecies of the Saharan region 31 compounds were separated, where α-pinene (16%), β-Ocimene (12.82%), dl-Limonene (8.20%) were the main components. The results of the disc diffusion method showed that the two volatile oils have efficient antibacterial activity but, subsp. laperrinei essential oil has a higher range of inhibition, in which P. aeruginosa and B. subtilis showed an extreme sensitivity, while the K. pneumoniae bacterium shows a great resistance to the two essential oils.

description: A statistical scenario is proposed to explain the $γ$-ray variability and flares of the Crab nebula, which were observed recently by the Fermi/LAT. In this scenario electrons are accelerated in a series of knots, whose sizes follow a power-law distribution. These knots presumably move outwards from the pulsar and have a distribution in the Doppler boost factor. The maximal electron energy is assumed to be proportional to the size of the knot. Fluctuations at the highest energy end of the overall electron distribution will result in variable $γ$-ray emission via the synchrotron process in the $\sim 100$ MeV range. Since highly boosted larger knots are rarer than smaller knots, the model predicts that the variability of the synchrotron emission increases with the photon energy. We realize such a scenario with a Monte-Carlo simulation and find that the model can reproduce both the two $γ$-ray flares over a period of $\sim$ year and the monthly scale $γ$-ray flux fluctuations as observed by the Fermi/LAT. The observed $γ$-ray spectra in both the steady and flaring states are also well reproduced.

description: Effective interactions, when defined in a coarse grained sense, such as Vlowk at the scale 450 MeV, display a remarkable symmetry pattern. Serber symmetry works with high accuracy for spin triplet states. Wigner SU(4) spin-isospin symmetry with nucleons in the fundamental representation works only for even partial waves exactly as predicted by large Nc limit of QCD with accuracy O(1/Nc^2). This suggests tailoring the very definition of effective interactions to provide a best possible fulfillment of long distance symmetries. With the Vlowk definition Wigner symmetry requires that chiral potentials have low cut-offs (450 MeV). Perturbative saturation of heavy mesonic resonances does not faithfully display the Serber symmetry pattern.

Automation in anesthesia : a look at L₁ adaptive and PID controllers
Creators: name: Talebian, Kousha
Publisher: name: University of British Columbia
Year: 2017

description: Control of anesthesia is one of the many tasks performed by anesthesiologists during surgery. It involves adjusting drug dosage by monitoring patient’s vital and clinical signs. A control system can replace this tedious and routine task, and allow the anesthesiologists to concentrate on more life threatening procedures. Because of large intra- and inter-variability in patients Pharmacokinetics and Pharmacodynamics responses, an adaptive controller is desirable. This thesis thoroughly investigates the L₁ Adaptive Control by applying it on 44 simulation cases which cover a wide range of patient demographics. It is found that the controller approaches an implantable non-adaptive LTI controller as the adaptation gain increases, echoing the results found by other researches. This loss of adaptivity is shown through examples and mathematical derivations. It is concluded that the L₁ Adaptive Control in its current form is not applicable to closed-loop control of anesthesia. As an alternative to adaptive controller, partial adaptivity in a PID controller is investigated. iControl, a PID controller designed by us, can sometimes lead to oscillation in the control signal. It is desirable to automatically detect the oscillations and tune the controller in order to remove them. A real-time oscillation detection algorithm is discussed. It detects multiple oscillations in real-time and provides their frequency, amplitude, severity and regularity. A PID auto-tuning algorithm is developed that uses the dominant frequency metrics provided by the oscillation detection algorithm to retune the controller robustly and to guarantee stability. This technique is simulated and tested on 44 cases; the gain and the phase margin in all 44 cases are within < 7% of the optimal tuning parameters of iControl.

description: The lowest electronic excitations of benzene and a set of donor-acceptor molecular complexes are calculated for the gas phase and on the Al(111) surface using the many-body Bethe-Salpeter equation (BSE). The energy of the charge-transfer excitations obtained for the gas phase complexes are found to be around 10% lower than the experimental values. When the molecules are placed outside the surface, the enhanced screening from the metal reduces the exciton binding energies by several eVs and the transition energies by up to 1 eV depending on the size of the transition-generated dipole. As a striking consequence we find that close to the metal surface the optical gap of benzene can exceed its quasiparticle gap. A classical image charge model for the screened Coulomb interaction can account for all these effects which, on the other hand, are completely missed by standard time-dependent density functional theory.

Creators: name: Schütt, Michael
Publisher: name: Karlsruhe
Year: 2013

description: We study the interplay of Coulomb interaction and transport in graphene. The impact of the interaction on graphene is analyzed by means of relaxation rates, in the language of an diagramatic perturbation theory, and by means of its kinetics, in the language of the Boltzman equation. The developed machinery is used to describe Coulomb drag properties of double layer graphene structures, matching the experimental observations.
PEDAGOGICAL CONDITIONS FOR THE FORMATION OF INCLUSIVE EDUCATION
Creators: name: Saidova, Nodira
Publisher: name: Zenodo
Year: 2023

description: Inclusive education goes beyond physical accessibility. It recognizes that people have different learning styles, abilities, interests and cultural backgrounds. These changes, in turn, required changes in the activities of special teachers, transformation of their functional responsibilities and, accordingly, a revision of the list of necessary professionally significant and personal qualities. This article shows that by now the general and methodological issues of training special teachers to work with children with disabilities abroad have been studied quite well. By adapting teaching methods and curriculum to account for these differences, educators can ensure that every student can actively participate in the learning process.

description: Periodontal pathogens alter the host immune response by perturbing expression of pro- and anti-inflammatory milieu. Inflammatory microenvironment in periodontal disease is largely governed by infiltration of myeloid cells. Periodontal therapy results in reduction of bacterial load that may instigate a pro-resolution environment favoring M2 Mφ polarization. Our previous studies demonstrated that human macrophages (Mφ) respond to live periopathogens, P. gingivalis (Pg) or A. actinomycetecomitans (Aa) and their LPS by polarizing towards the pro-inflammatory M1 phenotype. While studies have evaluated differences in M1 and M2 Mφ profiles or their markers in healthy versus periodontally diseased gingival tissues, to our knowledge there has been no longitudinal study evaluating the influence of periodontal therapy on Mφ polarization. In this study, we correlated clinical parameters and periopathogen load in human gingival biopsies after non-surgical periodontal therapy. Using well characterized markers for M1, M2 Mφ polarization, we found a decrease in the levels of M1 Mφ markers and the converse increase in M2 Mφ polarization markers in gingival biopsy samples obtained post-therapeutically which correlated with clinical improvement. Priming of Mφ within the gingival tissues is a well controlled axis and has considerable consequences for how Mφ detect, phagocytose and kill bacteria, and participate in tissue repair.

description: In this article, we study the topology of real analytic germs $F \colon (\C^3,0) \to (\C,0)$ given by $F(x,y,z)=\overline{xy}(x^p+y^q)+z^r$ with $p,q,r \in \N$, $p,q,r \geq 2$ and $(p,q)=1$. Such a germ gives rise to a Milnor fibration $\frac{F}{\mid F \mid} \colon \Sp^5\setminus L_F \to \Sp^1$. We describe the link $L_F$ as a Seifert manifold and we show that in many cases the open-book decomposition of $\Sp^5$ given by the Milnor fibration of $F$ cannot come from the Milnor fibration of a complex singularity in $\C^3$.

description: Gate bias stress instability in organic field-effect transistors (OFETs) is a major conceptual and device issue. This effect manifests itself by an undesirable shift of the transfer characteristics and is associated with long term charge trapping. We study the role of the dielectric and the semiconductor separately by producing OFETs with the same semiconductor (pentacene) combined with different dielectrics (SiO$_2$ and Cytop). We show, it is possible to fabricate devices which are immune to gate bias stress. For other material combinations, charge trapping occurs in the semiconductor alone, or in the dielectric.

description: Aharonov-Bohm (AB) oscillations are studied for a parallel coupled vertical double quantum dot with a common source and drain electrode. We observe AB oscillations of current via a one-electron bonding state as the ground state and an anti-bonding state as the excited state. As the center gate voltage becomes more negative, the oscillation period is clearly halved for both the bonding and antibonding states, and the phase changes by half a period for the antibonding state. This result can be explained by a calculation that takes account of the indirect interdot coupling via the two electrodes.

Subjects: Uncategorized

description: The purpose of this dissertation was to identify a transcriptomic profile of individuals with insomnia and explore the role of the glymphatic system and sleep disturbances in neurodegenerative disease and traumatic brain injury. The first paper reports whole blood transcriptomic analysis in individuals with insomnia using RNA sequencing technology. The study incorporated innovative high throughput sequencing platform with extended pathway analysis using QIAGEN’s Ingenuity® Pathway Analysis software to identify differentially expressed genes and pathways in individuals with insomnia. The second paper provides a critical review of the sleep-wake process and the glymphatic system and how these processes contribute to neurodegenerative disorders and traumatic brain injury. The research addresses an important gap in knowledge about underlying mechanism of insomnia and how sleep disturbance, the glymphatic pathway and neurologic conditions may be interrelated.

Nano-sized carbon-supported molybdenum disulphide particles for hydrodesulphurization
Creators: name: Solnickova, Lucie
Publisher: name: University of British Columbia

description: Canadian bitumen is a plentiful source of hydrocarbons. However, to obtain oils which may be sold to consumers, bitumen must be upgraded. Among other processes, bitumen upgrading includes lowering sulphur content and correcting the carbon to hydrogen ratio mostly by carbon rejection, which results in the formation of petroleum coke (PC), a byproduct which must be stored or disposed of. This study's focus was the preparation of a molybdenum disulphide (MoS₂) catalyst for a more facile removal of intercalated sulphur from bitumen, by synthesising nano-sized MoS₂ particles. Simultaneously, this study attempted to use PC as a catalyst support. Carbon-supported MoS₂ catalysts were successfully prepared by two methods using ammonium tetrathiomolybdate: reverse micelles using the water/IGEPAL CO-520/cyclohexane system, and incipient wetness impregnation from ultra pure water. MoS₂ prepared by impregnation was supported on PC, and MoS₂ prepared by reverse micelles was supported on both PC and activated carbon (AC). Catalysts prepared by reverse micelles contained nanosized MoS₂ with low stacking order, and the catalyst prepared by impregnation consisted of long sheets of MoS₂ with a higher stacking order. The catalysts were screened for hydrodesulphurization activity in a novel slurry-phase batch microreactor using dibenzothiophene as a model compound. The overall rate constant for DBT conversion per gram of molybdenum for the MoS₂/PC prepared by impregnation was greater than that for the catalysts prepared by reverse micelles in the temperature range of 350 - 375 °C. MoS₂ supported on AC and PC showed a similar activity toward catalysing the HDS of DBT when the MoS₂ was prepared by reverse micelles; therefore, PC is a good alternative support to AC for MoS₂/C catalysts prepared by this method. The rate constant associated with hydrogenation was an order of magnitude greater for the catalyst prepared by impregnation than that for the catalysts prepared by reverse micelles. It was concluded that the larger stacking order in MoS₂/PC prepared by impregnation provided more sites for hydrogenation, which resulted in an overall larger rate constant than that for the catalysts prepared by reverse micelles, whose MoS₂ stacking orders were minimal due to the small particle size.

description: We discuss the classical tests of general relativity in the presence of Rindler acceleration. Among these tests the perihelion shifts give the tightest constraints and indicate that the Pioneer anomaly cannot be caused by a universal solar system Rindler acceleration. We address potential caveats for massive test-objects. Our tightest bound on Rindler acceleration that comes with no caveats is derived from radar echo delay and yields |a|<3nm/s^2.
