description: We theoretically describe the spin excitation spectrum of a two dimensional electron gas embedded in a quantum well with localized magnetic impurities. Compared to the previous work, we introduce equations that allow to consider the interplay between the Coulomb interaction of delocalized electrons and the $sd$ exchange coupling between electrons and magnetic impurities. Strong qualitative changes are found : mixed waves propagate below the single particle continuum, an anticrossing gap is open at a specific wavevector and the kinetic damping due to the electron motion strongly influences the coupling strength between electrons and impurities spins.

description: We present 65 Sloan Digital Sky Survey (SDSS) spectra of 62 star-forming galaxies with oxygen abundances 12 + logO/H ~ 7.5-8.4. Redshifts of selected galaxies are in the range z~0.36-0.70. This allows us to detect the redshifted MgII 2797,2803 emission lines. Our aim is to use these lines for the magnesium abundance determination. The MgII emission was detected in ~2/3 of the galaxies. We find that the MgII 2797 emission-line intensity follows a trend with the excitation parameter x= O^{2+}/O that is similar to that predicted by CLOUDY photoionised HII region models, suggesting a nebular origin of MgII emission. The Mg/O abundance ratio is lower by a factor ~2 than the solar ratio. This is probably the combined effect of interstellar MgII absorption and depletion of Mg onto dust. However, the effect of dust depletion in selected galaxies, if present, is small, by a factor of ~2 lower than that of iron.

description: We verified the validity of the empirical method to derive the 4He abundance used in our previous papers by applying it to CLOUDY (v13.01) models. Using newly published HeI emissivities, for which we present convenient fits as well as the output CLOUDY case B hydrogen and HeI line intensities, we found that the empirical method is able to reproduce the input CLOUDY 4He abundance with an accuracy of better than 1%. The CLOUDY output data also allowed us to derive the non-recombination contribution to the intensities of the strongest Balmer hydrogen Halpha, Hbeta, Hgamma, and Hdelta emission lines and the ionisation correction factors for He. With these improvements we used our updated empirical method to derive the 4He abundances and to test corrections for several systematic effects in a sample of 1610 spectra of low-metallicity extragalactic HII regions, the largest sample used so far. From this sample we extracted a subsample of 111 HII regions with Hbeta equivalent width EW(Hbeta) > 150A, with excitation parameter x = O^{2+}/O > 0.8, and with helium mass fraction Y derived with an accuracy better than 3%. With this subsample we derived the primordial 4He mass fraction Yp = 0.254+/-0.003 from linear regression Y-O/H. The derived value of Yp is higher at the 68% confidence level (CL) than that predicted by the standard big bang nucleosynthesis (SBBN) model, possibly implying the existence of different types of neutrino species in addition to the three known types of active neutrinos. Using the most recently derived primordial abundances D/H = (2.60+/-0.12)x10^{-5} and Yp = 0.254+/-0.003 and the chi^2 technique, we found that the best agreement between abundances of these light elements is achieved in a cosmological model with baryon mass density Omegab h^2 = 0.0234+/-0.0019 (68% CL) and an effective number of the neutrino species Neff = 3.51+/-0.35 (68% CL).

description: (abridged) We studied a large sample of ~14000 dwarf star-forming galaxies with strong emission lines selected from the Sloan Digital Sky Survey (SDSS) and distributed in the redshift range of z~0-0.6. We modelled spectral energy distributions (SED) of all galaxies which were based on the SDSS spectra in the visible range of 0.38-0.92 micron and included both the stellar and ionised gas emission. These SEDs were extrapolated to the UV and mid-infrared ranges to cover the wavelength range of 0.1-22 micron. The SDSS spectroscopic data were supplemented by photometric data from the GALEX, SDSS, 2MASS, WISE, IRAS, and NVSS all-sky surveys. We derived global characteristics of the galaxies, such as their element abundances, luminosities, and stellar masses. The luminosities and stellar masses range within the sample over ~5 orders of magnitude, thereby linking low-mass and low-luminosity blue compact dwarf (BCD) galaxies to luminous galaxies, which are similar to high-redshift Lyman-break galaxies (LBGs). The luminosity L(Hbeta) of the Hbeta emission line, a characteristic of the youngest stellar population with an age of a few Myr, is correlated with luminosities in other wavelength ranges. This implies that the most recent burst of star formation makes a significant contribution to the emission in the visible range and dominates in other wavelength ranges. We found 20 galaxies with very red WISE mid-infrared m(3.4micron)-m(4.6micron) colour (>2 mag), which suggests the important contribution of the hot (with a temperature of several hundred degree) dust emission in these galaxies. Our analysis of the balance between the luminosity in the WISE bands that covered a wavelength range of 3.4-22 micron and the luminosity of the emission absorbed at shorter wavelengths showed that the luminosity of the hot dust emission is increased with increasing L(Hbeta) and EW(Hbeta).

description: Bacteria employ signaling proteins like bacterial histidine kinases (HKs) to sense environmental stimuli and initiate a transcriptional response through a series of conformational changes and enzymatic steps. Despite the prevalence of these receptors, we still lack significant understanding of how specific signals are detected and propagated through the protein scaffold to induce switch-like behavior with finely tuned specificity, sensitivity, and transcriptional output. Generating large-scale HK genotype-phenotype relationships will enable us to parse out allosteric networks that enable and regulate intramolecular signal transduction, providing molecular insights into the complex mechanisms by which these organisms sense and adapt to their environment.

description: We consider the coherent exciton transport, modeled by continuous-time quantum walks, on Erdös-Rény graphs in the presence of a random distribution of traps. The role of trap concentration and of the substrate dilution is deepened showing that, at long times and for intermediate degree of dilution, the survival probability typically decays exponentially with a (average) decay rate which depends non monotonically on the graph connectivity; when the degree of dilution is either very low or very high, stationary states, not affected by traps, get more likely giving rise to a survival probability decaying to a finite value. Both these features constitute a qualitative difference with respect to the behavior found for classical walks.

Study abstract:

The scale of phenological research has expanded due to the digitization of herbarium specimens and volunteer based contributions. These data are status-based, representing the presence or absence of a specific phenophase. Modelling the progress of plant dormancy to growth and reproduction and back to dormancy requires estimating the transition dates from these status-based observations. There are several methods available for this ranging from statistical moments using the day of year to newly introduced methods using concepts from other fields. Comparing the proficiency of different estimators is difficult since true transition dates are rarely known. Here I use a recently released dataset of in-situ flowering observations of the perennial forb Echinacea angustifolia. In this dataset, due to high sampling frequency and unique physiology, the transition dates of onset, peak, and end of flowering are known to within 3 days. I used a Monte Carlo analysis to test eight different estimators across two scales using a range of sample sizes and proportion of flowering presence observations. I evaluated the estimators accuracy in predicting the onset, peak, and end of flowering at the population level, and predicting onset and end of flowering for individual plants. Overall a method using a Weibull distribution performed the best for population level onset and end estimates, but other estimators may be more appropriate when there is a large amount of absence observations relative to presence observations. For individual estimates a method using the midway point between the first flower presence and most prior flower absence, within 7 days, is the best option as long as the restriction does not limit the final sample size. Otherwise the Weibull method is adequate for individual estimates as well. These methods allow practitioners to effectively utilize the large amount of status-based phenological observations currently available.

description: The electron spin-lattice relaxation of TEMPO and TEMPONE was measured at temperatures between 5 and 80 K in crystalline and glassy ethanol using X-band electron paramagnetic resonance spectroscopy. The experimental data at the lowest temperatures studied were explained in terms of electron-nuclear dipolar interaction between the paramagnetic center and the localized excitations, whereas at higher temperatures low-frequency vibrational modes from the host matrix and Raman processes should be considered. The strong impact of hydrogen bonding between the dopant molecule and ethanol host on the spin relaxation was observed in ethanol glass whereas in crystalline ethanol both paramagnetic guest molecules behaved similarly.

description: This thesis explores the ways in which certain forms of interactive art may and do elicit visceral responses. The term "visceral" refers to the cardiovascular, respiratory, uro-genital and especially excretory systems that affect mind and body on a continuum of awareness. The "visceral" is mentioned in the field of interactive arts, but it remains systematically unexplored and undefined. Further, interactive artworks predominantly focus on the exteroceptive (stimuli from outside) rather than the interoceptive (stimuli arising within the body, especially the viscera) senses. The existentialist phenomenology of Maurice Merleau-Ponty forms the basis for explorations of the visceral dimension of mind/body. New approaches to understanding interactive art, design and the mind/body include: attunements to the world; intertwinings of mind/body, technology and world; and of being in the world. Each artwork within utilizes a variation of the phenomenological methods derived from Merl eau-Ponty's; these are discussed primarily in Chapters One and Three. Because subjective, first-person, experiences are a major aspect of a phenomenological approach, the academic writing is interspersed with subjective experiences of the author and others. This thesis balances facets of knowledge from diverse disciplines that account for visceral phenomena and subjective experience. Along with the textual exegesis, one major work of design and two major works of art were created. These are documented on the compact disc (CDROM) bound within. As an essential component of each artwork, new technological systems were created or co-created by the author. User surveys comprise Appendices Two, Three and Four, and are also online at: www. sfu. ca/-dgromala/thesis. To access the URL: login as , and use the password . Numerous talks, exhibitions and publications that directly relate to the thesis work is in Appendix One. This work begins with an introduction to Merleau-Ponty's ideas of flesh and reversibility. Chapter Two is the review of the literature, while Chapter Three is an explication of the hypothesis, an overview of the field, and a framing of the problem. Discussions of each artwork are in Chapter Four (The Meditation Chamber), Chapter Five (BioMorphic Typography) and Chapter Six (The MeatBook). Chapter Seven forms the conclusion. References to the documentation on the CD are found throughout the thesis, and italicized paragraphs provide an artistic context for each chapter.

description: We present XMM-Newton and Chandra observations of two low-metallicity cometary blue compact dwarf (BCD) galaxies, Mrk 59 and Mrk 71. The first BCD, Mrk 59, contains two ultraluminous X-ray (ULX) sources, IXO 72 and IXO 73, both associated with bright massive stars and H II complexes, as well as one fainter extended source associated with a massive H II complex at the head of the cometary structure. The low-metallicity of Mrk 59 appears to be responsible for the presence of the two ULXs. IXO 72 has varied little over the last 10 yr, while IXO 73 has demonstrated a variability factor of ~4 over the same period. The second BCD, Mrk 71, contains two faint X-ray point sources and two faint extended sources. One point source is likely a background AGN, while the other appears to be coincident with a very luminous star and a compact H II region at the "head" of the cometary structure. The two faint extended sources are also associated with massive H II complexes. Although both BCDs have the same metallicity, the three sources in Mrk 71 have X-ray luminosities ~1-2 orders of magnitude fainter than those in Mrk 59. The age of the starburst may play a role.

description: We present near-infrared spectroscopic observations of the high-intensity HeI 10830 emission line in 45 low-metallicity HII regions. We combined these NIR data with spectroscopic data in the optical range to derive the primordial He abundance. The use of the HeI 10830A line, the intensity of which is very sensitive to the density of the HII region, greatly improves the determination of the physical conditions in the He^+ zone. This results in a considerably tighter Y - O/H linear regression compared to all previous studies. We extracted a final sample of 28 HII regions with Hbeta equivalent width EW(Hbeta)>150A, excitation parameter O^2+/O>0.8, and with helium mass fraction Y derived with an accuracy better than 3%. With this final sample we derived a primordial He mass fraction Yp = 0.2551+/-0.0022. The derived value of Yp is higher than the one predicted by the standard big bang nucleosynthesis (SBBN) model. Using our derived Yp together with D/H = (2.53+/-0.04)x10^-5, and the chi^2 technique, we found that the best agreement between these light element abundances is achieved in a cosmological model with a baryon mass density Omega_b h^2 = 0.0240+/-0.0017 (68% CL), +/-0.0028 (95.4% CL), +/-0.0034 (99% CL) and an effective number of neutrino species Neff = 3.58+/-0.25 (68% CL), +/-0.40 (95.4% CL), +/-0.50 (99% CL). A non-standard value of Neff is preferred at the 99% CL, implying the possible existence of additional types of neutrino species.

description: The scale of phenology research has expanded due to the digitization of herbarium specimens and volunteer based contributions. These data are status-based, representing the presence or absence of a specific phenophase. Modelling the progress of plant dormancy to growth and reproduction and back to dormancy requires estimating the transition dates from these status-based observations. There are several methods available for this ranging from statistical moments using the Julian day to newly introduced methods using concepts from other fields. Comparing the proficiency of different estimators is difficult since true transition dates are rarely known. Here I use a recently released dataset of flowering observations where, due to high sampling frequency and unique physiology, the transition dates of onset, peak, and end of flowering are known. I used a Monte Carlo analysis to test estimators across two scales using a range of sample sizes and proportion of flowering presence observations. I tested estimates of onset, peak, and end of flowing at the population level, and estimates of onset and end for individual plants. Overall a recently introduced method using a Weibull curve performed the best for population level onset and end estimates, but other estimators may be more appropriate when there is a large amount of absence observations relative to presence observations. For individual estimates a method using the midway point between the first flower presence and most prior flower absence, within 7 days, is the best option as long as the restriction does not limit the final sample size. Otherwise the Weibull method is adequate for individual estimates as well.

description: The restoration of particle number within Energy Density Functional theory is analyzed. It is shown that the standard method based on configuration mixing leads to a functional of both the projected and non-projected densities. As an alternative that might be advantageous for mass models, nuclear dynamics and thermodynamics, we propose to formulate the functional in terms directly of the one-body and two-body density matrices of the state with good particle number. Our approach does not contain the pathologies recently observed when restoring the particle number in an Energy Density Functional framework based on transition density matrices and can eventually be applied with functionals having arbitrary density dependencies.

Near-infrared spectroscopy of a large sample of low-metallicity blue compact dwarf galaxies

description: We present near-infrared (NIR) spectroscopic observations in the wavelength range 0.90-2.40mum of eighteen low-metallicity blue compact dwarf (BCD) galaxies and six HII regions in spiral and interacting galaxies. Hydrogen and helium emission lines are detected in all spectra, while H2 and iron emission lines are detected in most spectra. The NIR data for all objects have been supplemented by optical spectra. In all objects, except perhaps for the highest metallicity ones, we find that the extinctions A(V) in the optical and NIR ranges are similar, implying that the NIR hydrogen emission lines in low-metallicity BCDs do not reveal more star formation than seen in the optical. We conclude that emission-line spectra of low-metallicity BCDs in the 0.36-2.40mum wavelength range are emitted by a relatively transparent ionized gas. The H2 emission line fluxes can be accounted for by fluorescence in most of the observed galaxies. We find a decrease of the H2 2.122mum emission line relative to the Brgamma line with increasing ionization parameter. This indicates an efficient destruction of H2 by the stellar UV radiation. The intensities of the [FeII] 1.257mum and 1.644mum emission lines in the spectra of all galaxies, but one, are consistent with the predictions of Cloudy stellar photoinization models. There is thus no need to invoke shock excitation for these lines, and they are not necessarily shock indicators in low-metallicity high-excitation BCDs. The intensity of the HeI 2.058mum emission line is lower in high-excitation BCDs with lower neutral gas column densities and higher turbulent motions.

description: We demonstrate coherent control of the optical transition of single Nitrogen-Vacancy defect centers in diamond. On applying short resonant laser pulses, we observe optical Rabi oscillations with a half-period as short as 1 nanosecond, an order of magnitude shorter than the spontaneous emission time. By studying the decay of Rabi oscillations, we find that the decoherence is dominated by laser-induced spectral jumps. By using a low-power probe pulse as a detuning sensor and applying post-selection, we demonstrate that spectral diffusion can be overcome in this system to generate coherent photons.

Roles of corrosion products of metal hip replacements in the etiology of adverse local tissue reactions

description: About two million people receive hip implants annually, to relieve the pain generated by osteoarthritis. Hip implants are composed of a titanium femoral stem and a Co-Cr-Mo head that articulates with a titanium-alloy acetabular cup, covered by a polyethylene liner (MoP). Other designs directly use a metal (Co-Cr-Mo) acetabular articulating surface (MoM). Concerns have arisen due to the elevated numbers of adverse local tissue reactions (ALTRs) to hip implants that generate pain and soft-tissue destruction. Due to the high rates of ALTRs in MoM implants, the corrosion products or wear particles from the metal surfaces are thought to trigger the immunological reactions. This thesis aimed to understand the mechanisms of ALTRs development through three studies: 1) histological analyses and comparison of ALTRs in MoM and MoP implants. 2) analysis of corrosion products in synovial fluid and tissues. 3) mechanistic study based on gene expression analysis of ALTRs, and cell culture of primary synovial fibroblasts that were exposed to Cr and Co.   The histological description of ALTRs showed structural similarities between MoM and MoP, with common elements such as tissue necrosis and the presence of perivascular lymphocyte aggregates. Significantly higher levels of metal ions were found in the synovial fluid of ALTR patients, but no differences in the particles present in tissues were found in ALTRs compared to non-ALTRs. The gene expression analysis of lymphocytes aggregates found an identical and non-specific Th1/Th2 reaction in ALTRs in both MoM and MoP, with no evidence of Th17 reaction. Finally, primary synovial fibroblasts responded to concentrations of metal ions observed in the synovial fluid of patients, by releasing pro-inflammatory cytokines. After 24 hours of exposure the secreted cytokines were demonstrated to be chemotactic for human monocytes which is a key processes during inflammation. These results support the hypothesis that metal ions from the hip implants trigger cytokine secretion by synovial fibroblasts, which initiate the immune reaction to hip replacements, providing evidence to reject the hypothesis of hypersensitivity as an etiologic factor of ALTRs.

description: X-band electron paramagnetic resonance (EPR) spectroscopy was used to study the spectral properties of a nitroxide spin probe in ethanol glass and crystalline ethanol, at 5 - 11.5 K. The different anisotropy of molecular packing in the two host matrices was evidenced by different rigid limit values for maximal hyperfine splitting in the signal of the spin probe. The significantly shorter phase memory time, , for the spin probe dissolved in crystalline ethanol, as compared to ethanol glass, was discussed in terms of contribution from spectral diffusion. The effect of low-frequency dynamics was manifested in the temperature dependence of and in the difference between the data measured at different spectral positions. This phenomenon was addressed within the framework of the slow-motional isotropic diffusion model [S. Lee, and S. Z. Tang, Phys. Rev. B 31, 1308 (1985)] predicting the spin probe dynamics within the millisecond range, at very low temperatures. The shorter spin-lattice relaxation time of the spin probe in ethanol glass was interpreted in terms of enhanced energy exchange between the spin system and the lattice in the glass matrix due to boson peak excitations.

description: Evidence is presented for the necessity of including duality violations in a consistent description of spectral function moments employed in the precision determination of $α_s$ from $τ$ decay. A physically motivated ansatz for duality violations in the spectral functions enables us to perform fits to spectral moments employing both pinched and unpinched weights. We describe our analysis strategy and provide some preliminary findings. Final numerical results await completion of an ongoing re-determination of the ALEPH covariance matrices incorporating correlations due to the unfolding procedure which are absent from the currently posted versions. To what extent this issue affects existing analyses and our own work will require further study.

description: The one-particle density of states (1P-DOS) in a system with localized electron states vanishes at the Fermi level due to the Coulomb interaction between electrons. Derivation of the Coulomb gap uses stability criteria of the ground state. The simplest criterion is based on the excitonic interaction of an electron and a hole and leads to a quadratic 1P-DOS in the three-dimensional (3D) case. In 3D, higher stability criteria, including two or more electrons, were predicted to exponentially deplete the 1P-DOS at energies close enough to the Fermi level. In this paper we show that there is a range of intermediate energies where this depletion is strongly compensated by the excitonic interaction between single-particle excitations, so that the crossover from quadratic to exponential behavior of the 1P-DOS is retarded. This is one of the reasons why such exponential depletion was never seen in computer simulations.

Safety-preserving control of systems with multiplicative model uncertainty with application to closed-loop anesthesia

Publisher: name: University of British Columbia

description: To convince the public to employ new technologies in their daily life, the reliability and safety of such technologies must be demonstrated. Verification of safety is more crucial in applications which may directly jeopardize human safety. A self- driving car is an example of such a technology in which the safety of passengers and pedestrians depends on the car’s actions made based on its perception of the environment. A closed-loop drug delivery system is another example of a safety-critical technology for which there are risks of drug over/under-dosing and adverse side effects. Uncertainty is the key challenge in safety verification of these technologies. In the self-driving car example, the uncertainty is in the car’s knowledge of the environment. In the context of closed-loop drug delivery systems, uncertainty is in the patient response to drugs due to inter-patient variability (model uncertainty). Unmeasurablity of variables indicating the system’s safety (e.g. drug concentrations in the plasma) is another source of problems in safety verification of technologies such as closed-loop anesthesia. Motivated by closed-loop anesthesia, this thesis aims to develop a mathematical framework for formal safety verification and safety-preserving control of safety-critical systems with model uncertainty. This extends formal methods and existing safety-preserving control techniques to systems with a certain class of multiplicative model uncertainty. Moreover, this work proposes one of the first safety- preserving control schemes for output-feedback control systems in which safety- critical variables are not measurable. We also extend this technique to uncertain output-feedback systems. In this work, we employ the developed techniques to design and formalize a safety system for closed-loop anesthesia. Finally, we propose a novel approach to reduce conservatism of the formalized safety system by reducing model uncertainty using model falsification. The results discussed in this thesis may facilitate the process of obtaining regulatory approvals for closed-loop anesthesia, which helps the emergence of this technology (and other closed-loop drug delivery systems) in clinical environments.

description: Building upon the intrinsic properties of Navier-Stokes dynamics, namely the prevalence of intense vortical structures and the interrelationship between vorticity and strain rate, we propose a simple framework to quantify the extreme events and the smallest scales of turbulence. We demonstrate that our approach is in excellent agreement with the best available data from direct numerical simulations of isotropic turbulence, with Taylor-scale Reynolds number up to 1300. We additionally highlight a shortcoming of prevailing intermittency models due to their disconnection from observed correlation between vorticity and strain. Our work accentuates the importance of this correlation as a crucial step in developing an accurate understanding of intermittency in turbulence.

description: Measuring the full three-dimensional motions of extra-galactic objects in the Universe presents a seemingly insurmountable challenge. In this paper we investigate the application of a technique to measure tangential motion that has previously only been applied nearby within the Local Group of galaxies, to clusters of galaxies far beyond its borders. We show that mapping the mean line-of-sight motion throughout a galaxy cluster could in principle be used to detect the "perspective rotation" induced by the projection of the cluster's tangential motion into the line-of-sight. The signal will be most prominent for clusters of the largest angular extent, most symmetric intrinsic velocity distribution and surveyed with the largest number of pointings possible. We investigate the feasibility of detecting this signal using three different approaches: measuring line-of-sight motions of individual cluster members; taking spectra of intracluster gas; and mapping distortions of the Cosmic Microwave Background radiation. We conclude that future spectroscopic surveys of 1000's of members of nearby galaxy clusters hold the most promise of measuring cluster tangential motions using this technique.
