description: A radio interferometer only measured the electric field at a given set of point distributed in space. The correlation between this measurements can be used to reconstruct an image of the sky. However, in order to do so, the interferometer has to apply phase shifts that are proportional to the distance in between the satellite in the observed direction. Thereby, the interferometer must know the orientation between its satellites and the observed direction. For a ground-based interferomter, this is not a problem as the position of the antennas remain unchanged. Nevertheless, for a swarm of satellite around the moon, it is an issue because their relative positions are in constant motion. The objective of this study was to explore the possibility of using the interferomter's imaging capacity to use it like a star tracker. The idea was to figure out if the interferomter was able to know its orientation without using an external element like a GNSS. The principle of a star-tracker is as followed: a camera takes a picture of the sky in the direction it is looking at, the pattern formed by the stars in the image is compared to the ones already known and referenced in a catalog, when a match is found the camera knows how it is orientated in the sky and so does the satellite. For the interferometer, the individual orientations are known but the relative positions of the satellites is measured in an unknown frame named "system frame". This frame has to be linked to the absolute inertial frame in which the celestial bodies are studied.

description: The purpose of this paper is to provide a micro-economic foundation for an argument that the direct employment by the government is more desirable than the government purchase of private goods to eliminate unemployment. A general equilibrium model with monopolistic competition is devised, and the effects of policies (government purchase, tax rate operation, and government employment) on macroeconomic variables (consumption, price, and profit) are investigated. It is shown that 1) the government purchase is inflationary in the sense that additional effective demand by the government not only increases private employment but also raises prices; 2) the government employment can achieve full employment without causing a rise in prices.

description: Modified by a logarithmic term, the non-linear electrodynamics (NED) model of the Born-Infeld (BI) action is reconsidered. Unlike the standard BI action, this choice provides interesting integrals of the Einstein-NED equations. It is found that the spherical matching process for a regular black hole entails indispensable surface stresses that vanish only for a specific value of the BI parameter. This solution represents a classical model of an elementary particle whose radius coincides with the horizon. In flat space time, a charged particle becomes a conducting shell with a radius proportional to the BI parameter.

title: Approximation for response adaptive designs using Stein's method
Creators: name: Shahrokhian, Anita
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Stein's method introduced by Charles Stein (1972) is a powerful tool in distributional approximation, especially in classes of random variables that are stochastically dependent. In recent years, researchers have concentrated more on adaptive designs. For the response adaptive randomization procedures, the patient's allocation depends on the aggregated information that is acquired from the responses of the previously treated patients. This design uses the information of patients' responses to modify treatment allocation in order to assign more patients to a successful treatment, thus introduce dependent structure in the data. In this thesis we investigate the use of Stein's method in statistical inference for response adaptive design. We have acquired asymptotic normality of the maximum likelihood estimators for treatment effects by deriving an upper bound for these estimators using Stein's method. We examine the performance of three types of response adaptive designs under various success probabilities through simulation studies. Since adaptive designs generate a dependent sequence of random variables that are not exchangeable, we present the advantage of using bootstrap re-sampling in adaptive designs and the efficiency of this method. We compare bootstrap confidence intervals with the asymptotic confidence interval under different success rates of three allocation methods. Also, we discuss the normal approximation based on the Wald's statistic in the numerical studies.

description: 3D scene understanding involves extracting critical geometry details from 2D images, including depth maps, camera position, and surface normals, providing insights into spatial arrangements. It also encompasses high-level vision tasks such as object recognition and semantic segmentation. In contrast to manual feature engineering, deep learning methods aim to improve efficiency and accuracy in learning visual geometry. This thesis focuses on three vital aspects: depth estimation from stereo inputs, object detection and segmentation, and 3D scene reconstruction, all utilizing neural networks to enhance geometry understanding with a deep learning approach, offering robust and efficient solutions for these challenges.

description: In 70's there was discovered a construction how to attach to some algebraic-geometric data an infinite-dimensional subspace in the space k((z)) of the Laurent power series. The construction is known as the Krichever correspondence. It was applied in the theory of integrable systems, particularly, for the KP and KdV equations. We show that the Krichever construction can be generalized to the case of dimension 2. We also include a known description of connection between the KP hierarchy in the Lax form and the vector fields on infinite Grassmanian manifolds and a construction of the semi-infinite monomes for the field k((z)) which is an important part of the theory of Sato Grassmanian. The text was published in Communications in Algebra, 29(2001), No.9, 4157-4181. This version includes a corrected proof of the proposition 2. Also, we include some additional remarks on the deduction of concrete equations from the Lax hierarchy and appendix 2.

description: We consider a quantum quench in a system of free bosons, starting from a thermal initial state. As in the case where the system is initially in the ground state, any finite subsystem eventually reaches a stationary thermal state with a momentum-dependent effective temperature. We find that this can, in some cases, even be lower than the initial temperature. We also study lattice effects and discuss more general types of quenches.

description: In this work we investigate the Sobolev space $\mathrm{H}^{1}(\partialΩ)$ on a strong Lipschitz boundary $\partialΩ$, i.e., $Ω$ is a strong Lipschitz domain. In most of the literature this space is defined via charts and Sobolev spaces on flat domains. We show that there is a different approach via differential operators on $Ω$ and a weak formulation directly on the boundary that leads to the same space. This second characterization of $\mathrm{H}^{1}(\partialΩ)$ is in particular of advantage, when it comes to traces of $\mathrm{H}(\operatorname{curl},Ω)$ vector fields.

description: The displacement- and frequency-noise-free interferometer (DFI) is a multiple laser interferometer array for gravitational wave detection free from both the displacement noise of optics and laser frequency noise. So far, partial experimental demonstrations of DFI have been done in 2-D table top experiments. In this paper, we report the complete demonstration of a 3-D DFI. The DFI consists of four Mach-Zehnder interferometers with four mirrors and two beamsplitters. The displacement noises both of mirrors and beamsplitters were suppressed by up to 40 dB. The non-vanishing DFI response to a gravitational wave was successfully confirmed using multiple electro-optic modulators and computing methods.
Cryogenic photonic testing and packaging
Creators: name: Lin, Becky
Publisher: name: University of British Columbia
Year: 2024

description: The widespread adaptation of systems relying on optically-controlled quantum information will require reliable and efficient multi-channel fibre-to-chip connections that function at cryogenic temperatures. Contrary to the matured automated measurement systems and packaging methodologies at room temperature (RT), there are limited solutions for efficient and robust cryogenic fibre-to-chip coupling due to challenges such as thermal-induced stresses and inaccessibility of the cryogenic testing environment. In this thesis, we present two methods to realize optical coupling between fibre-to-chip at cryogenic temperature. The first method utilizes piezo stages to align to multiple devices which allows high-volume device measurements and parameter characterization per cool-down cycle. However, this method is prone to signal loss due to large misalignments stemming from mechanical contractions inside the cryostat and the lack of reliable position feedback. We show that this can be mitigated by using on-chip optical feedback and following a set of navigation strategies. For permanent coupling strategies, we study a new packaging technology, photonic wire bonding, that uses free-form 3D polymer structures to connect the fibre and the photonic chip facet. Large misalignment tolerance, high bandwidth, and low insertion loss are some of the attractive features of this emerging method. First, we examine some factors, such as the quality of the facet and power of the polymer writing laser, that can influence its performance at RT. Afterwards, we apply it to cryogenic optical packaging. Again, we will see that thermal contraction poses a challenge to the application of this method at cryogenic temperature and we show, that with adjusted assembling methodology and attention to material properties, we can overcome this challenge and achieve a coupling of 2 dB between a single mode fibre and tapered silicon waveguide down to 5 K.
RATAN-600 7.6-cm Deep Sky Strip Surveys at the Declination of the SS433 Source During the 1980-1999 Period. Data Reduction and the Catalog of Radio Sources in the Right-Ascension Interval 7h < R.A. < 17h

description: We use two independent methods to reduce the data of the surveys made with RATAN-600 radio telescope at 7.6 cm in 1988-1999 at the declination of the SS433 source. We also reprocess the data of the "Cold" survey (1980-1981). The resulting RCR (RATAN COLD REFINED) catalog contains the right ascensions and fluxes of objects identified with those of the NVSS catalog in the right-ascension interval 7h < R.A. < 17h. We obtain the spectra of the radio sources and determine their spectral indices at 3.94 and 0.5 GHz. The spectra are based on the data from all known catalogs available from the CATS, Vizier, and NED databases, and the flux estimates inferred from the maps of the VLSS and GB6 surveys. For 245 of the 550 objects of the RCR catalog the fluxes are known at two frequencies only: 3.94 GHz (RCR) and 1.4 GHz (NVSS). These are mostly sources with fluxes smaller than 30 mJy. About 65% of these sources have flat or inverse spectra (alpha > -0.5). We analyze the reliability of the results obtained for the entire list of objects and construct the histograms of the spectral indices and fluxes of the sources. Our main conclusion is that all 10-15 mJy objects found in the considered right-ascension interval were already included in the decimeter-wave catalogs.

silence

description: Empecemos por el principio y acordemos que el silencio no pertenece a las cosas, sino a nuestra relación con ellas.  Hay silencio cuando no hay señal que podamos, sepamos, queramos o deseemos detectar.  Con la ecuación silencio = no-señal, iniciamos la exploración de lo que no sabemos. Un museo de lo que no sabemos no contiene objetos, autores o presencias. Sería un espacio para cosechar todo lo que nos hemos perdido, todo lo que estamos dejando morir y no sabemos darle existencia. Sería un lugar para reeducar la mirada, el oído, el tacto y el deseo. Operaría como el espacio seguro donde preguntarnos si estamos mirando hacia lo que importa o en la dirección más necesaria.  Y no hay que desdeñar la posibilidad de que gran parte de lo que no sabemos, ni siquiera lo echemos de menos.  Un museo del silencio no es tampoco es espacio para acumular carencias, no debería funcionar como repositorio de lo que nos falta, sino de todo eso cuya presencia no reclama perfiles definidos, trayectorias claras, presencias nítidas, síntomas registrables, signos codificados o gestos reconocibles.  Forman parte del silencio los mundos espectrales, fantasmagóricos, pálidos, difusos, desenfocados o diluidos, como también nos interesan las intermitencias, las fugacidades o los desvanecimientos.

description: Spaces where each element describes a shape, so-called shape spaces, are of particular interest in shape optimization and its applications. Theory and algorithms in shape optimization are often based on techniques from differential geometry. Challenges arise when an application demands a non-smooth shape, which is commonly-encountered as an optimal shape for fluid-mechanical problems. In order to avoid the restriction to infinitely-smooth shapes of a commonly-used shape space, we construct a space containing shapes in $\mathbb{R}^2$ that can be identified with a Riemannian product manifold but at the same time admits piecewise-smooth curves as elements. We combine the new product manifold with an approach for optimizing multiple non-intersecting shapes. For the newly-defined shapes, adjustments are made in the known shape optimization definitions and algorithms to ensure their usability in applications. Numerical results regarding a fluid-mechanical problem constrained by the Navier-Stokes equations, where the viscous energy dissipation is minimized, show its applicability.

description: We show how to distribute with percentage success probabilities almost perfectly entangled qubit memory pairs over repeater channel segments of the order of the optical attenuation distance. In addition to some weak, dispersive light-matter interactions, only Gaussian state transmissions and measurements are needed for this scheme, which even beats the coherent-state-benchmark for entanglement distribution based on error-free non-Gaussian measurements. This is achieved through two innovations: first, optical squeezed states are utilized instead of coherent states. Secondly, the amplitudes of the bright signal pulses are reamplified at each repeater station. This latter variation is a strategy reminiscent of classical repeaters and would be impossible in single-photon-based schemes.

description: The phase-resetting curve (PRC) describes the response of a neural oscillator to small perturbations in membrane potential. Its usefulness for predicting the dynamics of weakly coupled deterministic networks has been well characterized. However, the inputs to real neurons may often be more accurately described as barrages of synaptic noise. Effective connectivity between cells may thus arise in the form of correlations between the noisy input streams. We use constrained optimization and perturbation methods to prove that PRC shape determines susceptibility to synchrony among otherwise uncoupled noise-driven neural oscillators. PRCs can be placed into two general categories: Type I PRCs are non-negative while Type II PRCs have a large negative region. Here we show that oscillators with Type II PRCs receiving common noisy input sychronize more readily than those with Type I PRCs.

description: Most Globular Clusters are believed to host a single stellar populations. They can thus be considered a good place to study the Spite plateau and probe for possible evolutionary modifications of the Li content. We want to determine the Li content of subgiant (SG) and Main Sequence (MS) stars of the old, metal-poor globular cluster NGC 6397. This work was aimed not only at studying possible Li abundance variations but to investigate the cosmological Li discrepancy. Here, we present FLAMES/GIRAFFE observations of a sample of 84 SG and 79 MS stars in NGC 6397 selected in a narrow range of B-V colour and, therefore, effective temperatures. We determine both Teff and A(Li) using 3D hydrodynamical model atmospheres for all the MS and SG stars of the sample. We find a significant difference in the Li abundance between SG stars and MS stars, the SG stars having an A(Li) higher by almost 0.1 dex on average. We also find a decrease in the A(Li) with decreasing Teff, both in MS and SG stars, albeit with a significantly different slope for the two classes of stars. This suggests that the lithium abundance in these stars is, indeed, altered by some process, which is Teff-dependent. The Li abundance pattern observed in NGC 6397 is different from what is found among field stars, casting some doubt on the use of Globular Cluster stars as representative of Population II with respect to the Li abundance. None of the available theories of Li depletion appears to satisfactorily describe our observations.

The Cosmological Lithium Problem is truly "cosmological"
Creators: name: Simpson, Jeffrey
Publisher: name: Zenodo
Year: 2021

description: The ESA Gaia astrometric mission has enabled the remarkable discovery that a large fraction of the stars near the Solar neighbourhood appear to be debris from a single in-falling system, the so-called Gaia-Enceladus. One exciting feature of this result is that it gives astronomers for the first time a large sample of easily observable, unevolved stars that formed in an extra-Galactic environment, which can be compared to stars that formed within our Milky Way. In this talk I will discuss using these stars to investigate the “Spite Plateau” – the near-constant lithium abundance observed in metal-poor dwarf stars across a wide range of metallicities (-3 < [Fe/H] < -1). In particular our aim was to test whether the stars that formed in Gaia-Enceladus show a different Spite Plateau to Milky Way stars that inhabit the disk and halo. Individual galaxies could have different Spite Plateaus – e.g., the interstellar medium could be more depleted in lithium in a lower galactic mass system due to it having a smaller reservoir of gas. We find that the Gaia-Enceladus stars show the same lithium abundance as other likely accreted stars and in situ Milky Way stars, strongly suggesting that the “lithium problem” is not a consequence of the formation environment. This result fits within the growing consensus that the Spite Plateau, and more generally the “cosmological lithium problem” – the observed discrepancy between the amount of lithium in warm, metal-poor dwarf stars in our Galaxy, and the amount of lithium predicted to have been produced by Big Bang Nucleosynthesis – is the result of lithium depletion processes within stars.

description: We present the results of a Spitzer IRAC and MIPS 24 micron study of extended Lyman-alpha clouds (or Lyman-alpha Blobs, LABs) within the SSA22 filamentary structure at z = 3.09. We detect 6/26 LABs in all IRAC filters, four of which are also detected at 24 micron, and find good correspondence with the 850 micron measurements of Geach et al. 2005. An analysis of the rest-frame ultraviolet, optical, near- and mid-infrared colors reveals that these six systems exhibit signs of nuclear activity (AGN)and/or extreme star formation. Notably, they have properties that bridge galaxies dominated by star formation (Lyman-break galaxies; LBGs) and those with AGNs (LBGs classified as QSOs). The LAB systems not detected in all four IRAC bands, on the other hand, are, as a group, consistent with pure star forming systems, similar to the majority of the LBGs within the filament. These results indicate that the galaxies within LABs do not comprise a homogeneous population, though they are also consistent with scenarios in which the gas halos are ionized through a common mechanism such as galaxy-scale winds driven by the galaxies within them, or gravitational heating of the collapsing cloud itself.

Characterizing T cell and plasmacytoid dendritic cell signatures in early life of antibiotic exposed neonates
Creators: name: Jan-Abu, Sia Cecilia
Publisher: name: University of British Columbia
Year: 2024

description: The prevalence of allergic diseases including food allergies and asthma are increasing worldwide and substantial evidence suggests that this is driven, at least in part, by changes in Western lifestyle and early life environmental factors. The complex interaction between genetics and environment from gestation to the first year of life are believed to drive perturbations in immune development and education which significantly affect allergic diseases susceptibility and development. In mice vancomycin exposure from gestation up to the first 3 weeks after birth induces enhanced systemic allergy later in life. This systemic allergy mouse model was used to study allergy development in the perinatal period by interrogating T cell and plasmacytoid dendritic cell (pDC) signatures in 7-, 10- and 14-day old mice. By flow cytometry we found that the frequency of CD4⁺ T cells and type 2 CD8⁺ T cells (Tc2 cells) were temporally altered in the bone marrow of naive vancomycin exposed mice which has implications for allergy development since normal hematopoiesis can be impacted by this T cell activity. pDC activation state in vancomycin primed mice was also significantly different. Furthermore, serum IgE analysis suggests that by day 14 after birth, allergy prone immune development is ensuing. Overall, this study provides insight into specific cell subsets that may drive pro-allergic immune development in early life, and it provides a specific timeline in which such critical changes are occurring.

description: Recently several quantum search algorithms based on quantum walks were proposed. Those algorithms differ from Grover's algorithm in many aspects. The goal is to find a marked vertex in a graph faster than classical algorithms. Since the implementation of those new algorithms in quantum computers or in other quantum devices is error-prone, it is important to analyze their robustness under decoherence. In this work we analyze the impact of decoherence on quantum search algorithms implemented on two-dimensional grids and on hypercubes.

description: The space of possible behaviors complex biological systems may exhibit is unimaginably vast, and these systems often appear to be stochastic, whether due to variable noisy environmental inputs or intrinsically generated chaos. The brain is a prominent example of a biological system with complex behaviors. The number of possible patterns of spikes emitted by a local brain circuit is combinatorially large, though the brain may not make use of all of them. Understanding which of these possible patterns are actually used by the brain, and how those sets of patterns change as properties of neural circuitry change is a major goal in neuroscience. Recently, tools from information geometry have been used to study embeddings of probabilistic models onto a hierarchy of model manifolds that encode how model behaviors change as a function of their parameters, giving a quantitative notion of "distances" between model behaviors. We apply this method to a network model of excitatory and inhibitory neural populations to understand how the competition between membrane and synaptic response timescales shapes the network's information geometry. The hyperbolic embedding allows us to identify the statistical parameters to which the model behavior is most sensitive, and demonstrate how the ranking of these coordinates changes with the balance of excitation and inhibition in the network.

description: Samples of two commercial low-density polyethylene melts were investigated with respect to their fracture behavior in controlled uniaxial extensional flow at constant strain rate in a filament stretching rheometer. In order to assess the possible influence of grain boundaries on fracture, the samples were prepared by three different types of pre-treatment: by compression molding of (1) virgin pellets used as received, (2) pellets homogenized in a twin-screw extruder, and (3) pellets that were milled into powder by cryogenic grinding under liquid nitrogen. The elongational stress growth data were analyzed by the Extended Hierarchical Multi-mode Molecular Stress Function (EHMMSF) model developed by Wagner et al. (Rheol. Acta 61, 281-298 (2022)) for long-chain branched (LCB) polymer melts. The EHMMSF model quantifies the elongational stress growth including the maximum in the elongational viscosity of LDPE melts based solely on the linear-viscoelastic relaxation spectrum and two nonlinear material parameters, the dilution modulus GD and a characteristic stretch parameter. Within experimental accuracy, model predictions are in excellent agreement with the elongational stress growth data of the two LDPE melts, independent of the preparation method used. At sufficiently high strain rates, the fracture of the polymer filaments was observed and is in general accordance with the entropic fracture criterion implemented in the EHMMSF model. High-speed videography reveals that fracture is preceded by parabolic crack opening, which is characteristic for elastic fracture and which has been observed earlier in filament stretching of monodisperse polystyrene solutions. Here, for the first time, we demonstrate the appearance of a parabolic crack opening in the fracture process of polydisperse long-chain branched polyethylene melts.

description: We present optical R-band light curves of five SDSS double QSOs (SDSS J0903+5028, SDSS J1001+5027, SDSS J1206+4332, SDSS J1353+1138, SDSS J1335+0118) obtained from monitoring at the Nordic Optical Telescope (NOT) between September 2005 and September 2007. We also present analytical and pixelated modeling of the observed systems. For SDSS J1206+4332, we measured the time delay to be 116 days, which, for a Singular Isothermal Ellipsoid model, corresponds to a Hubble constant of 73 km/s/Mpc. Simultaneous pixeleted modeling of five other systems for which a time delay has now been previously measured at the NOT leads to H_0 = 61.5 km/s/Mpc. Finally, by comparing lightcurves of the two images of each system, suitably shifted by the predicted or observed time-delays, we found no evidence for microlensing variability over the course of the monitoring period.

description: Chemical composition of the massive cores forming high-mass stars can put some constrains on the time scale of the massive star formation: sulphur chemistry is of specific interest due to its rapid evolution in warm gas and because the abundance of sulphur bearing species increases significantly with the temperature. Two mid-infrared quiet and two brighter massive cores are observed in various transitions (E_up up to 289K) of CS, OCS, H2S, SO, SO2 and of their isotopologues at mm wavelengths with the IRAM 30m and CSO telescopes. 1D modeling of the dust continuum is used to derive the density and temperature laws, which are then applied in the RATRAN code to model the observed line emission, and to derive the relative abundances of the molecules. All lines, except the highest energy SO2 transition, are detected. Infall (up to 2.9km/s) may be detected towards the core W43MM1. The inferred mass rate is 5.8-9.4 10^{-2} M_{\odot}/yr. We propose an evolutionary sequence of our sources (W43MM1-IRAS18264-1152-IRAS05358+3543-IRAS18162-2048), based on the SED analysis. The analysis of the variations in abundance ratios from source to source reveals that the SO and SO2 relative abundances increase with time, while CS and OCS decrease. Molecular ratios, such as [OCS/H2S], [CS/H2S], [SO/OCS], [SO2/OCS], [CS/SO] and [SO2/SO] may be good indicators of evolution depending on layers probed by the observed molecular transitions. Observations of molecular emission from warmer layers, hence involving higher upper energy levels are mandatory to include.

description: In recent years, discovery of association rules among itemsets in a large database has been described as an important database-mining problem. The problem of discovering association rules has received considerable research attention and several algorithms for mining frequent itemsets have been developed. Many algorithms have been proposed to discover rules at single concept level. However, mining association rules at multiple concept levels may lead to the discovery of more specific and concrete knowledge from data. The discovery of multiple level association rules is very much useful in many applications. In most of the studies for multiple level association rule mining, the database is scanned repeatedly which affects the efficiency of mining process. In this research paper, a new method for discovering multilevel association rules is proposed. It is based on FP-tree structure and uses cooccurrence frequent item tree to find frequent items in multilevel concept hierarchy.

Comparative study of biofilm in GDMF and PGDMF systems
Creators: name: Kumaran, Varshaa
Publisher: name: University of British Columbia
Year: 2024

description: Gravity-driven membrane filtration (GDMF) is a process in which hydrostatic pressure (gravity) serves as the driving force to maintain water flow through the membrane. Limited fouling control measures are applied, resulting in the formation of a biofilm layer on the membrane surface. This porous layer hosts a stable microbial community, crucial for sustaining water output. GDMF systems are simple to operate and cost-effective, making them well-suited for small-scale applications. Typically, the biofilm layer in GDMF systems enhances the removal of various contaminants, including organics and viruses. At the same time, the presence of the biofilm layer increases the resistance of to water flow, decreasing overall throughput. To increase the overall throughput, passive (gravity-driven) fouling controls, such as air scouring, and tank drain can be applied to GDMF systems. However, limited knowledge exists on the efficacy of these techniques. This present study addresses critical knowledge gaps in the literature regarding the effects of the passive fouling controls in gravity-driven membrane filtration systems; referred to as passive gravity-driven membrane filtration (PGDMF). The results of the study demonstrate that passive fouling controls significantly contribute to increased overall throughput. The study also concludes that passive fouling controls did not impact the chemical and biological properties of the biofilm layer developed on the membrane surface. The study also concludes that, after it is established at 1-2 weeks, the microbial community present on the biofilm layer is not similar to the microbial community present in the feed or reject of the PGDMF system.
