description: The point source list of the Wilkinson Microwave Anisotropy Probe (WMAP) is a uniform, all-sky catalogue of bright sources with flux density measurements at high (up to 94 GHz) radio frequencies. We investigated the five-year WMAP list to compile a new catalogue of bright and compact extragalactic radio sources to be potentially studied with Very Long Baseline Interferometry at millimeter wavelengths (mm-VLBI) and Space VLBI (SVLBI). After comparing the WMAP data with the existing mm-VLBI catalogues, we sorted out the yet unexplored sources. Using the 41, 61 and 94 GHz WMAP flux densities, we calculated the spectral indices. By collecting optical identifications, lower-frequency radio flux densities and VLBI images from the literature, we created a list of objects which have not been investigated with VLBI at 86 GHz before. With total flux density at least 1 Jy and declination above -40 degree, we found 37 suitable new targets. It is a nearly 25% addition to the known mm-VLBI sources. Such objects are also potentially useful as phase-reference calibrators for the future Japanese SVLBI mission ASTRO-G at its highest observing frequency (43 GHz). The phase-referencing capability of ASTRO-G would allow long integrations and hence better sensitivity for observing faint target sources close to suitable phase calibrators in the sky.

description: This paper reviews some of the many 3D numerical experiments of the emergence of magnetic fields from the solar interior and the subsequent interaction with the pre-existing coronal magnetic field. The models described here are idealized, in the sense that the internal energy equation only involves the adiabatic, Ohmic and viscous shock heating terms. However, provided the main aim is to investigate the dynamical evolution, this is adequate. Many interesting observational phenomena are explained by these models in a self-consistent manner.

Image quality and quantitation accuracy of penalized-likelihood reconstruction method for ¹⁸F and ⁹⁰Y
Creators: name: Ma, Hillgan
Publisher: name: University of British Columbia
Year: 2016

description: One application of PET/CT is diagnosis of tumours using ¹⁸F-FDG as a radiotracer. Early detection of small lesions is imperative to improve diagnosis. Recently, PET/CT was proposed to image ⁹⁰Y, (which has a small number (32ppm) of positrons emitted from internal pair production), as a tool for verification of radiotracer distribution and dosimetry for radioembolization therapy. Ordered Subset Expectation Maximization (OSEM), the standard image reconstruction algorithm in the clinic, creates mottled images making small lesion detection for ¹⁸F and ⁹⁰Y PET imaging difficult. The penalized-likelihood (PL) reconstruction technique with a relative difference penalty (RDP) based on a block sequential regularized expectation maximization (BSREM) numerical optimizer can create smooth regions without compromising the edges. The objective of this thesis was to quantitatively compare small-lesion detectability and quantitation accuracy of BSREM with the OSEM algorithm. This was performed with and without time-of-flight (TOF) information in both phantom and patient studies for ¹⁸F and ⁹⁰Y. For ¹⁸F phantom experiments, standard International Electrotechnical Commission (IEC) spheres were scanned using 4 different signal-to-background (SBR) ratios (=Air, Water, 8 and 4). Four smaller spheres were scanned to evaluate the performance of the algorithms in detecting small objects. Image quality was analyzed using 60 lung and head/neck tumour patient scans. Images reconstructed using TOF-BSREM showed an increase of signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) for small spheres by 16±3% and 35±2% compared to OSEM. For the patient scans, TOF-BSREM did not show any improvements of CNR but an increase of 14±4% for SNR. The recovery of ¹⁸F activity in large spheres, was underestimated by 10%, while for small spheres, accuracy was even more decreased due to partial volume effect. For ⁹⁰Y scans, the same spheres were scanned with a SBR of 7.5. ⁹⁰Y images reconstructed using TOF-BSREM showed an improvement of SNR and CNR by 89±7% and 96±8% respectively. TOF-BSREM improved quantitation accuracy to 78% in contrast to 65% with OSEM, when physical boundaries of sphere were taken as the region-of-interest. In conclusion, SNR, CNR and quantitation accuracy improved for small spheres when using the TOF-BSREM algorithm.

description: In a recent series of papers, Gebremariam, Bogner, and Duguet derived a microscopically based nuclear energy density functional by applying the Density Matrix Expansion (DME) to the Hartree-Fock energy obtained from chiral effective field theory (EFT) two- and three-nucleon interactions. Due to the structure of the chiral interactions, each coupling in the DME functional is given as the sum of a coupling constant arising from zero-range contact interactions and a coupling function of the density arising from the finite-range pion exchanges. Since the contact contributions have essentially the same structure as those entering empirical Skyrme functionals, a microscopically guided Skyrme phenomenology has been suggested in which the contact terms in the DME functional are released for optimization to finite-density observables to capture short-range correlation energy contributions from beyond Hartree-Fock. The present paper is the first attempt to assess the ability of the newly suggested DME functional, which has a much richer set of density dependencies than traditional Skyrme functionals, to generate sensible and stable results for nuclear applications. The results of the first proof-of-principle calculations are given, and numerous practical issues related to the implementation of the new functional in existing Skyrme codes are discussed. Using a restricted singular value decomposition (SVD) optimization procedure, it is found that the new DME functional gives numerically stable results and exhibits a small but systematic reduction of our test $χ^2$ function compared to standard Skyrme functionals, thus justifying its suitability for future global optimizations and large-scale calculations.

An innovative daylighting system incorporating active light collection
Creators: name: Khosravi Simchi, Sepideh
Publisher: name: University of British Columbia
Year: 2015

description: The building industry recognizes the importance of incorporating daylighting into the illumination of buildings to improve both the energy performance of the building and the overall lighting quality. There are several well-known methods to increase the daylighting level in buildings, including windows and skylights. However, they are usually not capable of illuminating the core of the building, and may increase the energy usage of the building due to poor insulation. There are other systems designed for illuminating the core of buildings with daylighting, but they all have some limitations that have impeded widespread adoption. A daylighting system investigated in this PhD project offers a novel approach to illuminating the core of buildings. This system, so called the Two-Stage Core Sunlighting System, consists of active and passive optical elements that capture sunlight outside of the building and transfer it to the dark core. Active sunlight redirectors, mounted at the rooftop level edge of the building, track the sun throughout the day and redirect the sunlight towards building façades at a certain angle. Passive concentrator elements mounted on the façades of the building capture and concentrate the light and direct it into light guides. The sunlight is then distributed within the building via interior light guides that illuminate the building. The performance of the Two-Stage Core Sunlighting System was evaluated for five different cities. The energy savings calculations and the cost estimation showed that the Two-Stage Core Sunlighting System can provide a practical approach to daylighting a building without negatively impacting its overall energy performance. As a complement to the main research project, an analysis was carried out to determine whether performance improvements could be possible in the future. The analysis focused on modifications to the prismatic microstructured film, in particular the addition of reflective structures that may enhance the efficiency of the film by recapturing a portion of the energy that would otherwise be lost. Simulation results showed that such modifications do not substantially change the performance of the currently available microstructured films, but that they can improve the performance of a nanostructured film in future applications.

description: We investigate a distributed optimal control problem for a phase field model of Cahn-Hilliard type. The model describes two-species phase segregation on an atomic lattice under the presence of diffusion; it has been recently introduced by the same authors in arXiv:1103.4585v1 [math.AP] and consists of a system of two highly nonlinearly coupled PDEs. For this reason, standard arguments of optimal control theory do not apply directly, although the control constraints and the cost functional are of standard type. We show that the problem admits a solution, and we derive the first-order necessary conditions of optimality.

Climate change impacts on the kelp life history cycle
Creators: name: Hoos, Jennifer Piper Jorve
Publisher: name: University of British Columbia

description: Anthropogenic climate change will cause changes to the abundance, distribution, and survival of species in ecosystems worldwide. Kelps are foundation species that form the structure of temperate, marine ecosystems on coastlines worldwide. Kelps support highly productive communities that are ecologically and economically valuable, but are susceptible to the increases in environmental stressors associated with climate change. This susceptibility varies with life history stage, with macroscopic stages less sensitive to environmental stress than microscopic stages. I addressed the effects of climate change on the different life history stages of intertidal kelp from rocky shores on the Pacific coast of North America. I began with two studies on the interactive effects of multiple climate stressors on microscopic stages of kelp. Increasing temperature, CO₂, and UV caused mechanical and functional damage to zoospores during their motile phase, and caused further reductions in settlement, germination, and adhesion of the initial sessile phase of the life history cycle. Settlement style was also affected, with decreased time spent looking for suitable attachment locations and microenvironments, and overdispersion of spore settlement distribution, which has been shown to decrease fertilization rates and sporophyte abundance. In my final research chapter, I describe the effects of increases in frequency of extreme warming events on macroscopic juvenile and adult kelp sporophytes. I also manipulated adult density in situ to determine the stress ameliorating affect of neighbor proximity on both juvenile recruitment and seasonal adult growth along a vertical tidal gradient. Extreme warming treatments reduced recruitment and seasonal growth of adults in the upper shore when adult density was low and environmental stressors were not mitigated by neighboring individuals. All other treatment combinations showed slightly positive effects of warming on recruitment and adult size. I predict that the aforementioned population effects resulting from increases in frequency of extreme warming events will cause an overall reduction in this species’ habitable vertical space in the intertidal zone. The combined impacts of overall reductions in microscopic life history stages with decreasing recruitment and habitable space for the macroscopic life history stage indicate overall reductions in abundance of future populations of intertidal kelp species.

Structural properties related to mesophyll conductance and underlying variation in leaf mass area of balsam poplar (Populus balsamifera L.)
Creators: name: Milla-Moreno, Estefania
Publisher: name: University of British Columbia
Year: 2015

description: In leaves, the ease with which CO₂ may diffuse from substomatal cavities to the sites of carboxylation (mesophyll conductance, gm) is inversely proportional to the pathway length in the gas phase and the structural resistances encountered in the liquid phase. Increased length of any pathway component should decrease gm, whereas increased area for diffusion should increase gm. There is evidence that within native balsam poplar (Populus balsamifera L.) populations, gm may increase with latitude of origin, as do leaf mass (LMA) and nitrogen per unit area. To investigate the internal structural characteristics that might limit maximum gm in leaves, a balsam poplar family (K4×C) known to have high variation in LMA was chosen. Several whole tissue properties (LMA, carbon-nitrogen ratio, chlorophyll concentration index), microanatomy traits (leaf thickness, intercellular air space, cell wall surface area, chloroplast counts), and ultrastructural attributes (cell wall thickness, thylakoid grana thickness, and cell wall area adjacent to chloroplasts) were measured. There were significant genotypic differences in chlorophyll concentration index, numbers of chloroplasts per mesophyll cell, leaf thickness (tleaf), and thicknesses and cross-sectional areas of the palisade and spongy mesophyll layers. There were also differences in the fraction of intercellular air space (fias), as well as total and exposed cell wall surface areas of the mesophyll and its component tissues. Although genotypic differences in LMA were not significant, LMA varied as a function of tleaf (r=0.515, p<0.05) and fias (r=-0.510, p<0.05), which together explained considerable variation in this trait. The single best correlate of LMA was the cell wall area of the palisade (r=0.813, p<0.001), which accounted for well over half of the total cell wall area of the mesophyll. The areas of mesophyll cell walls and chloroplasts exposed to intercellular air space, both of which should contribute to gm, also increased with LMA. Along the same lines, but not correlated with LMA, there was a decrease in nitrogen density per unit exposed mesophyll surface area associated with thicker leaves (r=-0.481, p<0.05).

Space charge effects in linear quadrupole ion traps
Creators: name: Gao, Cong
Publisher: name: University of British Columbia
Year: 2015

description: Space charge effects in a linear quadrupole ion trap operated with mass selective axial ejection have been investigated. If too many ions are confined in an ion trap, the Coulomb repulsion between ions, or from "space charge", causes ions to shift towards higher apparent mass-to-charge ratio (m/z) in a mass spectrum. This phenomenon, called "mass shifts", can be described by a model with the assumption that the trapped ions have a Boltzmann or thermal distribution of positions in an effective potential. The two parameters in this model, the ion temperature and the effective potential, are determined in this thesis, allowing improved modelling of space charge effects with well determined parameters. Space charge effects were also studied experimentally, including the simplest case (self-space charge) and the most difficult case (space charge from a heavy ion species of high abundance). A new technique to lower mass shifts, dual-frequency excitation, was introduced and optimized. As a result, the instrument performance of linear quadrupole ion trap mass analyzers, including the intensity, limits of detection and the trap capacity, can be improved.

We find a nonmonotonic dependence on strain, which may be related to the proximity to several strain-induced electronic topological transitions. Given the relation between the Drude weight and the long-wavelength plasmon frequency, such a strain dependence can be evidenced by infrared spectroscopy measurements.

description: Quantum state reconstruction based on weak continuous measurement has the advantage of being fast, accurate, and almost non-perturbative. In this work we present a pedagogical review of the protocol proposed by Silberfarb et al., PRL 95 030402 (2005), whereby an ensemble of identically prepared systems is collectively probed and controlled in a time-dependent manner so as to create an informationally complete continuous measurement record. The measurement history is then inverted to determine the state at the initial time through a maximum-likelihood estimate. The general formalism is applied to the case of reconstruction of the quantum state encoded in the magnetic sublevels of a large-spin alkali atom, 133Cs. We detail two different protocols for control. Using magnetic interactions and a quadratic ac-Stark shift, we can reconstruct a chosen hyperfine manifold F, e.g., the 7-dimensional F=3 manifold in the electronic-ground state of Cs. We review the procedure as implemented in experiments (Smith et al., PRL 97 180403 (2006)). We extend the protocol to the more ambitious case of reconstruction of states in the full 16-dimensional electronic-ground subspace (F=3 \oplus F=4), controlled by microwaves and radio-frequency magnetic fields. We give detailed derivations of all physical interactions, approximations, numerical methods, and fitting procedures, tailored to the realistic experimental setting. For the case of light-shift and magnetic control, reconstruction fidelities of \sim 0.95 have been achieved, limited primarily by inhomogeneities in the light shift. For the case of microwave/RF-control we simulate fidelity >0.97, limited primarily by signal-to-noise.

Real-time grade estimation and online acceptance or rejection of mined material
Creators: name: Nayak, Preetham
Publisher: name: University of British Columbia
Year: 2015

description: The mineral industry is currently challenged by low metal prices and depletion of high grade resources with increasing depth combined with complex geology. Achieving profits in-spite of these difficulties has been challenging and the standard industry response to tackle the situation is by pursuing economy of scale. Only large scale companies can adopt this method due to the high capital investment involved. The alternate solution is to recognize and introduce low cost mining and mineral processing methods. The current research aims at increasing profitability of a mining operation by efficiently utilizing the mineral resource and increase the recovery. The research focuses on exploiting inherent heterogeneity in an orebody with the development of a sophisticated tool that can perform real time, with online analysis and decision support systems to designate the destination of the material being mined. The research includes measuring and modeling a deposit’s heterogeneity at both BHP Billiton’s Spence and Escondida mines. This is followed by the development of two digital models to evaluate the opportunity to adopt selective partitioning of ore, prior to hauling the mined material to the mill. An apparent increase in profitability is observed due to increased ore recovery. Determining and exploiting this heterogeneity offers different insights in orebody grade distribution, evaluating resources and reserves and production planning, all leading to more complete utilization of the resource.

description: In this paper, the lowest order constrained variational (LOCV) method has been used to investigate the magnetic properties of spin polarized neutron matter in the presence of strong magnetic field at zero temperature employing $AV_{18}$ potential. Our results indicate that a ferromagnetic phase transition is induced by a strong magnetic field with strength greater than $10^{18}\ G$, leading to a partial spin polarization of the neutron matter. It is also shown that the equation of state of neutron matter in the presence of magnetic field is stiffer than the case in absence of magnetic field.

description: A maioria dos estudos religiosos em Portugal tem centralizado o seu enfoque na Igreja Católica e nas diversas denominações protestantes. Contudo, durante o período ditatorial que envolveu o país de 1926 a 1974, e especialmente desde 1961, as autoridades portuguesas despenderam uma considerável quantidade de recursos e tempo investigando as Testemunhas de Jeová, cujo número de membros era aparentemente insignificante. Este artigo procurará entender as razões desse fenómeno e historiará a implantação desse movimento no território metropolitano e ultramarino, com destaque para Angola e Moçambique.

Eduardo Moreira e as missões protestantes no espaço colonial português: ecos de um projeto pedagógico de evangelização na primeira metade do século XX
Creators: name: Leite, Rita Mendonça
Publisher: name: Lusitania Sacra
Year: 2012

description: A estruturação do protestantismo português resultou de um processo complexo dinamizado com uma consistência substancial sobretudo a partir de finais do século XIX. No decorrer desse processo, várias figuras se destacaram na liderança de um movimento pioneiro, participando ativamente da construção da pluralidade religiosa no país. Eduardo Henriques Moreira (1886‑1980) sobressai entre esses líderes pela amplitude do seu campo de ação e pela abrangência e densidade da sua reflexão. Na década de 30 (séc. XX), a viagem que levou a cabo pelos territórios africanos de dominação portuguesa, produziu uma influência determinante no seu pensamento e na sua visão sobre o papel do protestantismo em Portugal e da missionação evangélica no Império Português. Defendendo a noção de uma unidade nacional que abrangia necessariamente os territórios coloniais, o plano de evangelização projetado por Eduardo Moreira assentava antes de mais na necessidade de promoção da instrução em Portugal e, por conseguinte, nas suas colónias, onde o potencial e a importância das missões evangélicas adquiriram uma abrangência que nunca alcançariam efetivamente na metrópole.

Sin embargo, la devoción al Santo Niño de Cebú en la costa chica tuvo sus propias particularidades: la imagen de marfil representando al Niño Dios estaba en manos de una familia afro‑mestiza, acusada por el cura del pueblo de idolatría, lo que alarmó a las autoridades del Tribunal de la Inquisición de la ciudad de México, y cuyo voluminoso expediente es la causa de este trabajo.

Discursos historiográficos sobre la figura del indio mesoamericano en el siglo XVI y la obra de fray Bernardino de Sahagún
Creators: name: López Meraz, Óscar Fernando
Publisher: name: Lusitania Sacra
Year: 2012

description: El texto describe brevemente algunos de los discursos históricos interesados en estudiar los contactos entre europeos y americanos en el siglo XVI, poniendo especial atención en un tipo de etnografía que se apoya en crónicas elaboradas por frailes para construir un “canon mesoamericano” y elaborar una prehispanicidad con tintes nacionalistas en el contexto mexicano. Como respuesta a este tipo de interpretación, se propone un acercamiento que procura comprender el discurso sobre el indio del siglo XVI para conocer las formas y los fines con los que se elaboraron documentos como los de Bernardino de Sahagún.

description: Der Beitrag stellt einen neuartigen Ansatz zur automatischen Erzeugung beliebiger strukturierter Prozeßmodelle vor, der es erlaubt, den Ingenieur bei einem der zeitaufwendigsten im Rahmen der Automatisierung komplexer Prozesse anfallenden Arbeiten - der Modellierung des Prozesses - effizient zu unterstützen. Ausgehend von den grundlegenden Ideen des "genetischen Programmierens" wurde ein Konzept für ein wirkungsvolles Werkzeug für den Ingenieur entwickelt, das am Beispielprozeß einer Fluß-Stauhaltung experimentell untersucht wurde.

description: TechTIDE project, funded by the European Commission Horizon 2020 research and innovation program [AD-1], will establish a pre-operational system to demonstrate reliability of a set of TID (Travelling Ionospheric Disturbances) detection methodologies to issue warnings of the occurrence of TIDs over the region extended from Europe to South Africa. TechTIDE warning system will estimate the parameters that specify the TID characteristics and the inferred perturbation, with all additional geophysical information to the users to help them assess the risks and to develop mitigation techniques, tailored to their application. This document is TechTIDE D2.1 “Report on the design and specifications of the TID algorithms and products” and it is an output of TechTIDE Task 2.1 (Specifications for the TID algorithms and the resulting products) of the WP2 (TID identification methodologies) which has the final goal to release the basic algorithms for the TID identification and the value-added products for implementation in the TechTIDE warning system. The document presents the design of adjusted and upgraded TID detection codes, the design of the value-added products, and the validation plan. The design of the adjustments and the upgrades of the different methods are based on the initial requirements gathered among potential users affected by TIDs [RD-1]. Some requirements were brought in from ESA Space Situational Awareness Space Weather (SSA SWE) [RD-2] users' requirements. This way, TID algorithms and product outputs will try to adapt to assess ESA SSA SWE Service Network prerequisites.

Droplet formation on demand at a microfluidic T-junction
Creators: name: He, Kelly Min
Publisher: name: University of British Columbia

description: Microfluidic aliquot dispensing technologies have been utilized in many chemical or biological high throughput assays to provide high-speed deposition of high-resolution droplets. Particularly, these aliquots can be used to dispense a controlled volume of liquid into multi-well plates in drug screening applications. However, existing platforms are often designed to print a limited set of materials where each material is handled by an independently actuated nozzle. A more convenient and scalable technology that could allow digital output of multiple materials on demand must be explored. Monodispered droplets can be formed continuously in a microfluidic T-junction when two input flows of immiscible fluids are maintained. However, it is difficult to form stable air separated aliquots in a simple T-junction configuration. Electrowetting-on-dielectric (EWOD) is commonly used to control individual droplets in a planar configuration. But it is not usually used in microfluidic channels. In this device, a new method for creating air separated aliquots on demand using EWOD at a microfluidic T-junction was demonstrated. Since air is the carrier fluid, these aliquots can be dispensed without further liquid processing. A device that consists of SU-8 channels with electrodes in alignment with the channels was designed and fabricated. A double wedged junction was incorporated at the dispersed channel to create a barrier pressure that allows the meniscus location to be controlled by the applied pressures. Droplets of approximately 15 nL can be generated by applying a voltage at the electrode at the junction. Liquid flow is stopped when the voltage is removed. This mechanism can be used as a digital valve to generate a sequence of aliquots of different materials for a multi-material printing platform.
On Mitigation of the Uncertainty in Nonlinear Matter Clustering for Cosmic Shear Tomography

description: We present a new method that deals with the uncertainty in matter-clustering in cosmic shear power spectrum analysis that arises mainly due to poorly understood nonlinear baryonic processes on small-scales. We show that the majority of information about dark energy physics contained in the shear power comes from these small-scales; removing these nonlinear scales from a cosmic shear analysis results in a 50% cut in the accuracy of measurements of dark energy parameters, marginalizing over all other parameters. In this paper we propose a method to recover the information on small-scales by allowing cosmic shear surveys to measure the nonlinear matter power spectrum themselves and marginalize over all possible power spectra using path integrals. Information is still recoverable in these nonlinear regimes from the geometric part of weak lensing. In this self-calibration regime we find we recover 90% of the information on dark energy. Including an informative prior, we find the nonlinear matter power spectrum needs to be accurately known to 1% down to k=50 h/Mpc to recover 99% of the dark energy information. This presents a significant theoretical challenge to understand baryonic effects on the scale of galaxy haloes. However self-calibration from weak lensing may also provide observational input to help constrain baryon physics.
