Identifying epigenetic associations with cell type and gestational age in the neonatal immune system
Creators: name: De Goede, Olivia Mae
Publisher: name: University of British Columbia
Year: 2016

description: Neonates have a uniquely structured immune system characterized by immunotolerance, an unprimed adaptive immune system, and a heavy reliance on innate immune responses. Although this prevents excessive hyperinflammatory responses during gestation and postnatal microbial colonization of the neonate, it also confers vulnerability to infection. This risk is heightened in those born preterm (prior to 37 weeks gestation), as development of their immune system is interrupted by early birth. Throughout gestation, the predominant hematopoietic organ shifts in a defined temporal pattern. Each hematopoietic source produces different types of immune cells in different proportions, to accommodate the needs of the developing fetus. One of the greatest differences between these organs is the release of nucleated red blood cells (nRBCs) into circulation – ranging from the yolk sac, which exclusively releases primitive nRBCs, to the bone marrow, in which erythroid cells are enucleated before entering circulation. Although generally regarded as a consequence of high erythropoietic demand in the fetus, recent functional studies have indicated an immunosuppressive role for fetal nRBCs as well. DNA methylation (DNAm) is the addition of a methyl group to a cytosine base, a modification which does not change the underlying genetic sequence. DNAm mediates hematopoietic lineage commitment and can be a useful marker for cell composition and immune function in blood. Using the Illumina Infinium HumanMethylation450 BeadChip microarray, this thesis establishes DNAm profiles for major cord blood hematopoietic cells in both term and preterm births. In-depth examination of DNAm in term nRBCs revealed that epigenetic marks in this enigmatic cell population are likely highly regulated. Comparisons between cord blood hematopoietic cells collected from term versus preterm births allowed for the identification of both cell-specific and systemic prematurity-associated differential methylation. These findings contribute to current understanding of the molecular mechanisms behind preterm birth and highlight candidate genes for follow-up gene expression or functional analysis of preterm hematopoietic cell populations, including CDC42EP1, CLIP2, FBXO31, the oncogene WWTR1, and tumour suppressor genes STK10 and RARRES3.

description: We show that the magnetization of a thin ferromagnetic (Ga,Mn)As layer can be modulated by picosecond acoustic pulses. In this approach a picosecond strain pulse injected into the structure induces a tilt of the magnetization vector M, followed by the precession of M around its equilibrium orientation. This effect can be understood in terms of changes in magneto-crystalline anisotropy induced by the pulse. A model where only one anisotropy constant is affected by the strain pulse provides a good description of the observed time-dependent response.

description: We present a semiclassical model for plasmon-enhanced high-harmonic generation (HHG) in the vicinity of metal nanostructures. We show that both the inhomogeneity of the enhanced local fields and electron absorption by the metal surface play an important role in the HHG process and lead to the generation of even harmonics and to a significantly increased cutoff. For the examples of silver-coated nanocones and bowtie antennas we predict that the required intensity reduces by up to three orders of magnitudes and the HHG cutoff increases by more than a factor of two. The study of the enhanced high-harmonic generation is connected with a finite-element simulation of the electric field enhancement due to the excitation of the plasmonic modes.

description: Supernovae are the most energetic stellar events and influence the interstellar medium by their gasdynamics and energetics. By this, both also affect the star formation positively and negatively. In this paper, we review the development of the complexity of investigations aiming at understanding the interchange between supernovae and their released hot gas with the star-forming molecular clouds. Commencing from analytical studies the paper advances to numerical models of supernova feedback from superbubble scales to galaxy structure. We also discuss parametrizations of star-formation and supernova-energy transfer efficiencies. Since evolutionary models from the interstellar medium to galaxies are numerous and apply multiple recipes of these parameters, only a representative selection of studies can be discussed here.

Improved characterization and movement of the platinum band in a proton exchange membrane fuel cell
Creators: name: Damron, David Luke
Publisher: name: University of British Columbia
Year: 2016

description: Proton exchange membrane (PEM) fuel cells are devices that produce zero emission electricity, offering one pathway towards a sustainable energy future. They are in the early stages of commercialization in automotive, backup power and mobile power applications, with cost and lifetime of the cells still representing major barriers. Platinum (Pt) degradation in a PEM fuel cell leads to reduced performance and lifetime, while raw material costs represent a large portion of the overall cost. One of the Pt degradation modes leads to Pt dissolving from the cathode and precipitating in the membrane, forming a “Pt band”. The Pt band is disconnected and unused Pt. If this Pt could be moved, it might be able to be returned to the cathode and be made useful again. This Pt can also have effects on membrane degradation. Pt bands were created in two unique locations using accelerated stress tests (AST) of 10,000 square wave potential cycles from 0.6-1.0V. The locations of the bands were accurately predicted using an existing model and are dependent on the concentrations of oxygen and hydrogen in the membrane. It was hypothesized that increasing the oxygen concentration around the Pt particles in the membrane, would lead to dissolution and movement of the Pt. A new more quantified analysis of the Pt band using SEM imaging is implemented to measure the Pt movement and more fully characterize the Pt band. After two experiments, one trying to move the Pt for 28h and another for 100h, no Pt movement was observed. Another experiment created 2 Pt bands in the same membrane and characterized them for the first time. The second band formed in this experiment did not influence the first band, nor was it influenced by the first band during its formation. The new characterization techniques demonstrated that the distributions of Pt mass and particles were different for the bands formed in the two different locations, while the dual band displayed a superposition of these distributions. The differences distributions have never been quantified before and could have different effects on membrane degradation, which should be the focus of future work.

The stability of the fractional quantum Hall effect in topological insulators

description: With the recent observation of graphene-like Landau levels at the surface of topological insulators, the possibility of fractional quantum Hall effect, which is a fundamental signature of strong correlations, has become of interest. Some experiments have reported intra-Landau level structure that is suggestive of fractional quantum Hall effect. This paper discusses the feasibility of fractional quantum Hall effect from a theoretical perspective, and argues that while this effect should occur, ideally, in the $n=0$ and $|n|=1$ Landau levels, it is ruled out in higher $|n|$ Landau levels. Unlike graphene, the fractional quantum Hall effect in topological insulators is predicted to show an interesting asymmetry between $n=1$ and $n=-1$ Landau levels due to spin-orbit coupling.

description: The surveillance, analysis and ultimately the efficient long-term prediction and control of epidemic dynamics appear to be one of the major challenges nowadays. Detailed atomistic mathematical models play an important role towards this aim. In this work it is shown how one can exploit the Equation Free approach and optimization methods such as Simulated Annealing to bridge detailed individual-based epidemic simulation with coarse-grained, systems-level, analysis. The methodology provides a systematic approach for analyzing the parametric behavior of complex/ multi-scale epidemic simulators much more efficiently than simply simulating forward in time. It is shown how steady state and (if required) time-dependent computations, stability computations, as well as continuation and numerical bifurcation analysis can be performed in a straightforward manner. The approach is illustrated through a simple individual-based epidemic model deploying on a random regular connected graph. Using the individual-based microscopic simulator as a black box coarse-grained timestepper and with the aid of Simulated Annealing I compute the coarse-grained equilibrium bifurcation diagram and analyze the stability of the stationary states sidestepping the necessity of obtaining explicit closures at the macroscopic level under a pairwise representation perspective.

description: High harmonic spectra show that laser-induced strong field ionization of water has a significant contribution from an inner-valence orbital. Our experiment uses the ratio of H2O and D2O high harmonic yields to isolate the characteristic nuclear motion of the molecular ionic states. The nuclear motion initiated via ionization of the highest occupied molecular orbital (HOMO) is small and is expected to lead to similar harmonic yields for the two isotopes. In contrast, ionization of the second least bound orbital (HOMO-1) exhibits itself via a strong bending motion which creates a significant isotope effect. We elaborate on this interpretation by simulating strong field ionization and high harmonic generation from the water isotopes using the time-dependent Schrödinger equation. We expect that this isotope marking scheme for probing excited ionic states in strong field processes can be generalized to other molecules.

A study of state of health estimation methods for li-ion batteries
Creators: name: Shabbir, Hassan
Publisher: name: University of British Columbia
Year: 2016

description: Currently, battery management systems are battery chargers, commonly comprised of power electronic circuits, which lack the ability to accurately estimate the state of health of a battery. Since, batteries have a limited lifetime, repeated charge and discharge cycles quickly deteriorate the electrical properties of the battery. With the reduced capacity and several other changes in the state of health of a battery, the electronic device might malfunction. This research is aimed to provide on device upgrade for all battery management systems and battery chargers to include battery health monitoring ability. For the evaluation of state of health of batteries, two approaches are considered in parallel, Electrochemical Impedance Spectroscopy (EIS) and profiling through charge and discharge curves. For EIS, the initial focus of this research is to design and validate the hardware that can perform EIS scans over a desired range of frequencies. Based on the footprints of scan, a state of health classification algorithm is proposed which categorizes batteries according to the set threshold. The main contribution of this project to existing EIS technology is the eradication of the need of battery modeling and parameter estimation from Nyquist plot to find the state of health of a battery. Tests are performed on hardware prototype to validate the designed algorithm that shows State of Health estimation accuracy of almost 90%. Another method considered for State of Health estimation is profiling through charge and discharge curves of the Li Ion batteries. Raw profiling data is examined to decipher the correlation between shape of charge and discharge curves and state of health. From the charging profile of the battery, constant charge current duration parameter is identified to possess promising potential to provide information about state of health of a battery. The behavior of the parameter is investigated in detail with repeated laboratory tests on almost 200 samples gathered from five different battery vendors. This technique showed above 90% classification accuracy. Finally a comparison is drawn between the EIS technology and charge curve profiling method with respective advantages and disadvantages to emphasize the suitability of each technique for different field applications.

description: In order to accelerate molecular dynamics simulations, it is very common to impose holonomic constraints on their hardest degrees of freedom. In this way, the time step used to integrate the equations of motion can be increased, thus allowing, in principle, to reach longer total simulation times. The imposition of such constraints results in an aditional set of Nc equations (the equations of constraint) and unknowns (their associated Lagrange multipliers), that must be solved in one way or another at each time step of the dynamics. In this work it is shown that, due to the essentially linear structure of typical biological polymers, such as nucleic acids or proteins, the algebraic equations that need to be solved involve a matrix which is banded if the constraints are indexed in a clever way. This allows to obtain the Lagrange multipliers through a non-iterative procedure, which can be considered exact up to machine precision, and which takes O(Nc) operations, instead of the usual O(Nc3) for generic molecular systems. We develop the formalism, and describe the appropriate indexing for a number of model molecules and also for alkanes, proteins and DNA. Finally, we provide a numerical example of the technique in a series of polyalanine peptides of different lengths using the AMBER molecular dynamics package.

The shape effect resulting from the modulation of the sample width (geometric pinning) can essentially affect the DW depinning. We found a good agreement between the ratios of the critical values of the magnetic field and the spin-polarized current predicted by the theory and measured in the experiment.

description: Using a green approach and ultrasonic-assisted template-free five-step process, a novel heterogeneous catalyst, γ-Fe2O3@SiO2-CD/Ag hollow spheres (h-Fe2O3@SiO2-CD/Ag), was fabricated. The design of the catalyst was based on the synthesis of core-shell h-Fe2O3@SiO2 followed by amine functionalization, reaction with tosylated cyclodextrin and subsequent Ag(0) doping using hollyhock flowers collected from the Banaruiyeh District, in Larestan, Iran as extract-based reducing agent. The novel catalyst was fully characterized using SEM/EDX, BET, TGA, ICP-AES, FTIR, VSM and XRD techniques. The hybrid catalyst was successfully applied for promoting A3 and KA2 coupling reactions under mild and green conditions, i.e. ultrasonic irradiation at room temperature in aqueous media. Studying the reusability of the catalyst and Ag(0) nanoparticle leaching established that the catalyst can be recovered and reused with preserving its catalytic activity and negligible Ag(0) leaching for five reaction runs. Upon reusing for the sixth run, however, slight leaching of Ag(0) and consequently loss of catalytic activity was observed.

In a two year field experiment, N₂O fluxes from a grape (Vitis vinifera L.; Merlot) vineyard and an apple (Malus domestica Borkh; Ambrosia) orchard under microirrigation in the semiarid Okanagan Valley of British Columbia were measured using static chambers. Soil mineral N and organic carbon, environmental variables and fruit yield were also monitored. Treatments in the grape vineyard involved micro-irrigation types (Drip or Micro-sprinkler), nitrogen sources (surface-applied compost or fertigated Urea; 40kg N ha‐¹), and two floor managements (surface-applied shredded bark and wood Mulch or Clean - bare soil). Treatments in the apple orchard involved drip irrigation frequency (twice per day or twice per day on every 2nd day) delivering the same total amount of water, orchard floor management (Mulch or Clean) and nitrogen application rate applied as calcium nitrate by fertigation (20 or 40 g N tree‐¹). Spring thaw accounted for 30 to 50% of annual emissions in both experiments. Over a period of two complete years in the grape vineyard Micro-sprinkler irrigation reduced growing season N₂O emissions by 29% (compared to Drip) and on an annual basis Mulch decreased them by 28% (compared to Clean ). In the apple orchard irrigation every 2nd day reduced N₂O emissions by 30% and application of Mulch reduced them by 20%. Reduced drip irrigation frequency and mulching may provide an opportunity for suppressing N₂O emissions from drip-irrigated vineyards and orchards. There was alsolarge spatial variability of N₂O and CO₂ emissions with respect to distance relative to the apple tree and dripper locations. The emission factor (N emitted as N₂O per unit of total applied N) from the applied fertilizer (uncorrected for background emission) across all treatments averaged 2.8% in the vineyard and 2.4% in the orchard. The 1% default IPCC emission factor likely underestimates N₂O emissions from these systems.

description: We report new observations of the fundamental $J=1-0$ transition of HCl (at 625.918GHz) toward a sample of 25 galactic star-forming regions, molecular clouds, and evolved stars, carried out using the Caltech Submillimeter Observatory. Fourteen sources in the sample are also observed in the corresponding H\tscl\ $J=1-0$ transition (at 624.978GHz). We have obtained clear detections in all but four of the targets, often in emission. Absorptions against bright background continuum sources are also seen in nine cases, usually involving a delicate balance between emission and absorption features. From RADEX modeling, we derive gas densities and HCl column densities for sources with HCl emission. HCl is found in a wide range of environments, with gas densities ranging from $10^5$ to $10^7$~cm$^{-3}$. The HCl abundance relative to H$_2$ is in the range of $(3-30)\times10^{-10}$. Comparing with the chlorine abundance in the solar neighborhood, this corresponds to a chlorine depletion factor of up to $\sim$400, assuming that HCl accounts for one third of the total chlorine in the gas phase. The [\tfcl]/[\tscl] isotopic ratio is rather varied, from unity to $\sim$5, mostly lower than the terrestrial value of 3.1. Such variation is highly localized, and could be generated by the nucleosynthesis in supernovae, which predicts a \tscl\ deficiency in most models. The lower ratios seen in W3IRS4 and W3IRS5 likely confine the progenitors of the supernovae to stars with relatively large mass ($\ga$25M$_\sun$) and high metallicity (Z$\sim$0.02).

description: We present an "interferometric quasi-autocollimator" that employs weak value amplification to measure angular deflections of a target mirror. The device has been designed to be insensitive to all translations of the target. We present a conceptual explanation of the amplification effect used by the device. An implementation of the device demonstrates sensitivities better than 10 picoradians per root hertz between 10 and 200 hertz.

description: Abstract:
This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.

description: A comprehensive number of one-loop integrals in a theory with Wilson fermions at $r=1$ is computed using the Burgio-Caracciolo-Pelissetto algorithm. With the use of these results, the fermionic propagator in the coordinate representation is evaluated, thus making it possible to extend the Luscher-Weisz procedure for two-loop integrals to the fermionic case. Computations are performed with FORM and REDUCE packages.

description: Recently, various possible expressions for the vacuum-to-vacuum superstring amplitudes has been proposed at genus $g=3,4,5$. To compare the different proposals, here we will present a careful analysis of the comparison between the two main technical tools adopted to realize the proposals: the classical theta constants and the lattice theta series. We compute the relevant Fourier coefficients in order to relate the two spaces. We will prove the equivalence up to genus 4. In genus five we will show that the solutions are equivalent modulo the Schottky form and coincide if we impose the vanishing of the cosmological constant.

description: The nearby blue compact dwarf, NGC 2915, has its stellar disc embedded in a large, extended (~ 22 B-band scale-lengths) HI disc. New high-resolution HI synthesis observations of NGC 2915 have been obtained with the Australia Telescope Compact Array. These observations provide evidence of extremely complex HI kinematics within the immediate vicinity of the galaxy's star-forming core. We identify and quantify double-peaked HI line profiles near the centre of the galaxy and show that the HI energetics can be accounted for by the mechanical energy output of the central high-mass stellar population within time-scales of 10^6-10^7 yr. Full three-dimensional models of the HI data cube are generated and compared to the observations to test various physical scenarios associated with the high-mass star-forming core of NGC 2915. Purely circular HI kinematics are ruled out together with the possibility of a high-velocity-dispersion inter-stellar medium at inner radii. Radial velocities of ~ 30 km/s are required to describe the central-most HI kinematics of the system. Our results lend themselves to the simple physical scenario in which the young stellar core of the galaxy expels the gas outwards from the centre of the disc, thereby creating a central HI under-density. These kinematics should be thought of as being linked to a central HI outflow rather than a large-scale galactic blow-out or wind.

description: We derive an approximate local density functional for the exchange-correlation energy to be used in density-functional calculations of two-dimensional systems. In the derivation we employ the Colle-Salvetti wave function within the scheme of Salvetti and Montagnani [Phys. Rev. A 63, 052109 (2001)] to satisfy the sum rule for the exchange-correlation hole. We apply the functional for the two-dimensional homogeneous electron gas as well as to a set of quantum dots and find a very good agreement with exact reference data.

Birefringence induced polarization-independent and nearly all-angle transparency through a metallic film

description: We propose an birefringence route to perfect electromagnetic (EM) wave tunneling through a metallic film which relies on homogeneous birefringent coatings with moderate and positive parameters only. EM transparency is achieved in such an birefringent-metal-birefringent (BMB) structure for both polarizations and over nearly all incident angles. The stringent restrictions in conventional dielectric-metal-dielectric media, i.e., dielectrics with extremely negative permittivity, high magnetic field and polarization dependence (only for TE waves), are not required in our method. The criterion for perfect transmission is obtained by analyzing the effective medium theory and EM fields of such a birefringent structure. The solutions hold for lossless and lossy cases in a quite large frequency range.

Yeast population and community dynamics : their effect on the chemical and sensory profiles of inoculated and spontaneous Pinot noir and Chardonnay fermentations at a Canadian winery
Creators: name: Neuner, Marissa
Publisher: name: University of British Columbia
Year: 2016

description: The Okanagan Valley of British Columbia, Canada, has grown to include over 130 wineries, spanning 8,060 acres. As a result, competition within the local industry and has caused Okanagan winemakers to seek the production of a more sensorially unique product. Traditionally, inoculated fermentations are most commonly conducted by adding an abundance of a Saccharomyces cerevisiae yeast strain to produce consistent and specific chemical and sensory attributes in the wines; however, winemakers are choosing to showcase their unique winery yeast flora by conducting spontaneous fermentations. Spontaneous fermentations are conducted under the assumption that the fermentative yeast populations come from diverse winery resident organisms which, therefore, create different chemical and sensory profiles. Specifically, spontaneous and inoculated fermentations of Pinot noir and Chardonnay during the 2013 vintage at Quails’ Gate Estate Winery were assessed. Throughout fermentation these wines were subjected to both culture-dependent microsatellite analysis and isolate sequencing, as well as culture-independent Illumina MiSeq analysis. This determined the yeast populations conducting alcoholic fermentation and compared the capabilities of each method when studying yeast communities. Uniquely diverse yeast populations were found between spontaneous and inoculated fermentations of Pinot noir; however, yeast populations within inoculated and spontaneous Chardonnay treatments showed no differentiation. Unexpectedly, Pinot noir and Chardonnay fermentations were found to include non-Saccharomyces yeasts, specifically Hanseniaspora sp., throughout the entirety of fermentation in large relative abundance. Gas chromatography flame ionization detection (GC-FID) was conducted to determine the concentration differences of fermentation-derived chemicals associated with the identified yeast species fermenting both varietals; however, only isoamyl acetate, was found to differ between Pinot noir treatments. Sensory analysis revealed unique attributes were associated with the sensory profiles of inoculated or spontaneously fermented Pinot noir wines. The unique yeast communities found between inoculated and spontaneous fermentations of Pinot noir were responsible for slight chemical variation and unique sensory profiles between treatments. The similarity in yeast communities between inoculated and spontaneous fermentations of Chardonnay precluded chemical and sensory differences from occurring. Thus, to increase the chemical and sensory variation within wines and differentiate varietals from those fermented by competitors, wineries should consider producing both inoculated and spontaneous fermentations.
