description: We study the one-loop effective action for a generic two-dimensional dilaton gravity theory conformally coupled to $N$ matter fields. We obtain an explicit expression for the effective action in the weak-coupling limit under a suitable restriction of the dilaton potential asymptotics. Our result applies to the CGHS model as well as to the spherically symmetric general relativity. The effective action is obtained by using the background-field method, and we take into account the loop contributions from all the fields in the classical action and from the ghosts. In the large-$N$ limit, and after an appropriate field redefinition, the one-loop correction takes the form of the Polyakov-Liouville action.

description: We consider a one-dimensional totally asymmetric nearest-neighbor zero-range process with site-dependent jump-rates - an environment. For each environment p we prove that the set of all invariant measures is the convex hull of a set of product measures with geometric marginals. As a consequence we show that for environments p satisfying certain asymptotic property, there are no invariant measures concentrating on configurations with critical density bigger than $ρ^*(p)$, a critical value. If $ρ^*(p)$ is finite we say that there is phase-transition on the density. In this case we prove that if the initial configuration has asymptotic density strictly above $ρ^*(p)$, then the process converges to the maximal invariant measure.

Mine plan and reclamation program updates : a regulatory approach to reclamation and closure planning
Creators: name: Stevens, Victoria
name: Antill, Tim
Publisher: name: The University of British Columbia
Year: 2023

description: Under the Health, Safety and Reclamation Code for Mines in British Columbia (the Code), mines are required to submit updated Mine Plan and Reclamation Program Updates (5 Year Mine Update) to the BC Ministry of Energy, Mines and Low Carbon Innovation (EMLI) at least every 5 years. The content of 5 Year Mine Updates is outlined in both the Code, as well as most Mines Act permits; however, many proponents are unclear on the level of detail and purpose for the 5 Year Mine Updates. A new EMLI guidance document will provide proponents with direction on developing effective update reports. Titled “Developing a Five Year Reclamation and Liability Update for Mines in British Columbia”, the guidance document provides proponents with detailed information on developing Five Year Reclamation and Liability Updates, or 5YRLUs, that fulfill Code and permit requirements. While the 5YRLU is a compliance requirement, and a checkpoint for tracking progress of what was approved during the permitting process against current conditions, EMLI’s primary interests in these submissions is to determine the current site reclamation status; review proposed reclamation and closure progression, design, implementation, and monitoring; and to update the reclamation security bond based on existing site liabilities. It is also an opportunity to review updated Reclamation and Closure Plans and ensure that information from sources such as reclamation research, water quality modelling predictions, closure design reports, and End Land Use planning with Indigenous Nations are incorporated into the updated plan. The outcome of 5YRLUs can vary from no changes to the permit, to an amendment of the permit to update the reclamation security bond value, update permit language to be more enforceable, and potentially to add new conditions, if required, to fill regulatory gaps identified during the review process.

description: In the moderately long wavelength propagation regime, acoustic crystaldevices which size is of several wave lengths are studied by using thefinite-difference time domain method. It is shown by the focusing and imaging of a square shaped lens that the diffractive effects dominate over the refractive ones. Taking into account the well known Babinet principle, the major role of the device edge diffraction is shown. The first examples of imaging with a sonic plane lens and of an acoustic prism able to change the propagation direction of a plane wave are also presented here.
Role of Gigaxonin in the Regulation of Intermediate Filaments: a Study Using Giant Axonal Neuropathy Patient-Derived Induced Pluripotent Stem Cell-Motor Neurons

description: Patients with giant axonal neuropathy (GAN) exhibit loss of motor and sensory function and typically live for less than 30 years. GAN is caused by autosomal recessive mutations leading to low levels of gigaxonin, a ubiquitously-expressed cytoplasmic protein whose cellular roles are poorly understood. GAN pathology is characterized by aggregates of intermediate filaments (IFs) in multiple tissues. Disorganization of the neuronal intermediate filament (nIF) network is a feature of several neurodegenerative disorders, including amyotrophic lateral sclerosis, Parkinson's disease and axonal Charcot-Marie-Tooth disease. In GAN such changes are often striking: peripheral nerve biopsies show enlarged axons with accumulations of neurofilaments; so called "giant axons." Interestingly, IFs also accumulate in other cell types in patients. These include desmin in muscle fibers, GFAP (glial fibrillary acidic protein) in astrocytes, and vimentin in multiple cell types including primary cultures of biopsied fibroblasts. These findings suggest that gigaxonin may be a master regulator of IFs, and understanding its function(s) could shed light on GAN as well as the numerous other diseases in which IFs accumulate. However, an interaction between gigaxonin and IFs has not been detected and how IF accumulation is triggered in the absence of functional gigaxonin has not been determined. To address these questions I undertook a proteomic screen to identify the normal binding partners of gigaxonin. Prominent among them were several classes of IFs, including the neurofilament subunits whose accumulation leads to the axonal swellings for which GAN is named. Strikingly, human motor neurons (MNs) differentiated from GAN iPSCs recapitulate this key phenotype. Accumulation of nIFs can be rescued by reintroduction of gigaxonin, by viral delivery or genetic correction. GAN iPS-MNs do not display survival vulnerability in the presence of trophic factors, but do display increased cell death in the presence of oxidative stress. Preliminary experiments suggest that in iPS-MNs nIFs are degraded by contributions from both the proteasome and lysosome. Gigaxonin interacts with the autophagy protein p62 which has been implicated in the clearance of ubiquitin aggregates by the lysosome, and this interaction is greatly enhanced in conditions of oxidative stress. My data provide the first direct link between gigaxonin loss and IF aggregation, and suggest that gigaxonin may be a substrate adaptor for the degradation of IFs by autophagy, pointing to future approaches for reversing the phenotype in human patients.

description: We study the subgroup structure, Hecke algebras, quasi-regular representations, and asymptotic properties of some fractal groups of branch type. We introduce parabolic subgroups, show that they are weakly maximal, and that the corresponding quasi-regular representations are irreducible. These (infinite-dimensional) representations are approximated by finite-dimensional quasi-regular representations. The Hecke algebras associated to these parabolic subgroups are commutative, so the decomposition in irreducible components of the finite quasi-regular representations is given by the double cosets of the parabolic subgroup. Since our results derive from considerations on finite-index subgroups, they also hold for the profinite completions $\hat G$ of the groups G. The representations involved have interesting spectral properties investigated in math.GR/9910102. This paper serves as a group-theoretic counterpart to the studies in the mentionned paper. We study more carefully a few examples of fractal groups, and in doing so exhibit the first example of a torsion-free branch just-infinite group. We also produce a new example of branch just-infinite group of intermediate growth, and provide for it an L-type presentation by generators and relators.

description: Hematopoietic stem cells (HSCs) generate blood cells over a lifetime, remaining largely quiescent until replenishment is required. Mechanisms governing HSC function and quiescence are unknown however, precluding improvements in HSC-based therapies, functional ex vivo expansion, and experimental applications. Mitochondria and their diverse functions serve as a critical regulatory node in HSC physiology and function. While HSCs preferentially utilize glycolysis for ATP production, they contain high mitochondrial mass, indicative of an alternative purpose of HSC mitochondrial content that could resolve elusive mechanisms. Mitofusin 2 (Mfn2), a multifunctional, membrane-bound mitochondrial and endoplasmic reticulum (ER) protein, is an essential regulator of HSC biology, promoting HSC lymphoid potential by mediating intracellular calcium buffering through ER-mitochondrial tethering (Luchsinger et al., Nature 2016) and potentially preventing premature HSC aging. Despite these findings, Mfn2 may have additional impacts on HSC physiology, as Mfn2 has diverse roles in mediating mitochondrial dynamics and regulating intracellular processes. Furthermore, Mfn2 still remains only partially characterized in HSCs, as its potential effects on quiescence, overall aging, and additional physiological properties remain unknown. The goal of this thesis then is to investigate the potential additional roles of Mfn2 in HSC biology and lifelong homoeostasis through its diverse regulatory functions. Through targeted deletion in the murine hematopoietic system, we first found Mfn2 was required for HSC quiescence but dispensable for self-renewal, an unusual phenotype unlinking dormancy and functional potential. We then showed Mfn2 represses type I interferon (IFN) signaling in HSCs, a novel regulatory role independent of the immune signaling adapter mitochondrial antiviral signaling protein (Mavs). We further found Mfn2 inhibits both HSC cycling and type I IFN signaling by negatively regulating signal transducer and activator of transcription 1 (Stat1), an IFN-response transcription factor. However, Stat1 and Mfn2 also exhibited alternative regulatory roles in HSC function and lineage potential, indicative of complex regulatory interplay between Mfn2, mitochondria, and IFN signaling. Additionally, Mfn2 was shown to attenuate age-related changes in HSCs, connecting mitochondrial function and lifelong HSC homeostasis. Overall, these findings advance the fundamental role the mitochondrion has in HSC physiology and function, further resolving Mfn2 as an indispensable regulator of HSC biology.

description: An aging HIV population carries a magnified risk of degenerative conditions such as cardiovascular disease (CVD) and osteoporosis. Recent studies have demonstrated that the growing population of older HIV-infected women is at special risk for these complications. To what extent the metabolic consequences of menopause or other related disease predictors such as depression influence this gender disparity is not known. The overall goal of this dissertation is to better characterize the etiology of low bone density and accelerated CVD in HIV-infected postmenopausal women. Current gaps in knowledge surrounding women aging with HIV, particularly as it relates to CVD and bone loss, are discussed in Chapter One. Chapter Two reports findings from a systematic review of low bone density and fractures in HIV-infected postmenopausal women. To gain a better understanding of CVD risk in HIV-infected postmenopausal minority women, a cross-sectional study was conducted and is presented in Chapter Three. Quantitative findings from a longitudinal analysis of bone density in postmenopausal minority women with HIV are reported in Chapter Four. Finally, in Chapter Five, findings from the previous chapters are summarized and synthesized into a concluding chapter; implications and future recommendations are also discussed.

description: It is shown that the well-known non-Abelian static SU(2) black hole solutions have rotating generalizations, provided that the hypothesis of linearization stability is accepted. Surprisingly, this rotating branch has an asymptotically Abelian gauge field with an electric charge that cannot vanish, although the non-rotating limit is uncharged. We argue that this may be related to our second finding, namely that there are no globally regular slowly rotating excitations of the particle-like Bartnik-McKinnon solutions.

description: Die Nanotechnologie hat durch den Bedarf an immer kleineren Strukturen für integrierte Schaltungen gleichermaßen an technologischem wie grundsätzlichem Interesse zugenommen. In der Grundlagenforschung interessiert zum Beispiel, was sich an der klassischen Beschreibung vieler Phänomene ändert, wenn die Abmessungen der Strukturen immer kleiner werden, d.h. in mindestens einer Dimension die Ausdehnung im Bereich weniger Nanometer liegt. Damit sind die Strukturen nur noch wenige Atomabstände groß, also Schichten mit wenigen Atomlagen Dicke, bzw. wenige Atomreihen Breite oder Kluster mit wenigen Atomen. Uns interessiert hier besonders die Frage der Leitungsmechanismen für den elektrischen Strom und dessen Abhängigkeit von strukturellen Parametern. Die klassische Beschreibung (Ohm’sches Gesetz und Boltzmann’s Theorie) geht von frei beweglichen Ladungsträgern aus, die sich im Material eine kurze Strecke frei bewegen und dann nach einer Streuung sich wieder frei bewegen. Über die Mittelung vieler Wegstücke kommt der "konstante" Stromfluss zustande. Was ändert sich, wenn die Abmessungen in mindestens einer Richtung kleiner als die sogenannte frei Weglänge ist? Hier ist mit prinzipiellen Änderungen der Mechanismen zu rechnen, da dann auch die Wellennatur der Ladungsträger wesentlich in Erscheinung treten kann.

description: We present observations of a complete sub-sample of 20 radio galaxies from the Third Cambridge Catalog (3C) with redshift <0.3 obtained from VLT/MUSE optical integral field spectrograph. These data have been obtained as part of the survey MURALES (a MUse RAdio Loud Emission line Snapshot survey) with the main goal of exploring the Active Galactic Nuclei (AGN) feedback process in a sizeable sample of the most powerful radio sources at low redshift. We present the data analysis and, for each source, the resulting emission line images and the 2D gas velocity field. Thanks to their unprecedented depth (the median 3 sigma surface brightness limit in the emission line maps is 6X10^-18 erg s-1 cm-2 arcsec-2, these observations reveal emission line structures extending to several tens of kiloparsec in most objects. In nine sources the gas velocity shows ordered rotation, but in the other cases it is highly complex. 3C sources show a connection between radio morphology and emission line properties. Whereas, in three of the four Fanaroff and Riley Class I radio galaxies (FRIs), the line emission regions are compact, ~1 kpc in size; in all but one of the Class II radiogalaxies FRIIs, we detected large scale structures of ionized gas with a median extent of 17 kpc. Among the FRIIs, those of high and low excitation show extended gas structures with similar morphological properties, suggesting that they both inhabit regions characterized by a rich gaseous environment on kpc scale.

description: We find and solve a large class of integrable dynamical systems which includes Calogero-Sutherland models and various novel generalizations thereof. In general they describe $N$ interacting particles moving on a circle and coupled to an arbitrary number, $m$, of $su(N)$ spin degrees of freedom with interactions which depend on arbitrary real parameters $x_j$, $j=1,2,...,m$. We derive these models from SU(N) Yang-Mills gauge theory coupled to non-dynamic matter and on spacetime which is a cylinder. This relation to gauge theories is used to prove integrability, to construct conservation laws, and solve these models.

description: A growing body of research conducted globally has shown that parents may have a positive influence on sexual decision making and safe-sex practices of their children. The gendered nature of these conversations may be especially important, but attention to this dimension of parent-child communication remains limited. Using the qualitative data from the Linking Lives India study, this dissertation attempts to fill the gap in the current literature on role of gender in communication about sexual health between parents and their same sex adolescents in a rural tribal area in Maharashtra. It also attempts to look at the gender differences in experiences of intimacy among adolescents in the study site. Using the Theory of gender and power the study shows that gender disparities that arise from the three structures- sexual division of power (psycho-social factors), sexual division of labor (economic factors) and cathexis (social norms) generate different risks factors that affect women and girls negatively more than men and boys; specifically, in the context of sexual communication. The data elucidates that these exposures and risk factors affect mothers’ access to knowledge / information and ability to communicate with their daughters about sexual health. It also negatively affects girls’ ability to access information and communicate about sexual health with their mothers in comparison to their male counterpart.

description: Complex systems can exhibit unexpected large changes, e.g. a crash in a financial market. We examine the large endogenous changes arising within a non-trivial generalization of the Minority Game: the Grand Canonical Minority Game (GCMG). Using a Markov Chain description, we study the many possible paths the system may take. This 'many-worlds' view not only allows us to predict the start and end of a crash in this system, but also to investigate how such a crash may be avoided. We find that the system can be 'immunized' against large changes: by inducing small changes today, much larger changes in the future can be prevented.

Man versucht daher diese hohe Konzentration schnell zu erreichen, in dem man die Wachstumsrate der Mikroorganismen durch Anwendung hoher Substratkonzentration beschleunigt. Die meisten Mikroorganismen zeigen jedoch bei hohen Konzentrationen der leicht verstoffwechselbaren Substrate eine Katabolit-Repression, die zu einer starken Verminderung der Bildung der erwünschten Produkte führt. Die osmophilen (zuckertoleranten) Hefen zeigen dieses Verhalten nicht. Sie vertragen außerdem noch hohen osmotischen Druck, der bei hohen Substratkonzentrationen vorherrscht. Diese Hefen wurden nach dem zweiten Weltkrieg entdeckt und es dauerte recht lange, bis ihre Produktivität durch Stammverbesserung soweit erhöht wurde, dass sie zur Produktion eingesetzt werden konnten. Die Hefe Moniliella tomentosa var pollinis war die erste osmophile Hefe, die in der Industrie verwendet wurde. Das Verfahren mit dieser Hefe wurde von uns in Kooperation mit der Industrie erarbeitet. Aufbauend auf unsere Untersuchungen wurde von dieser Firma ein Prozess zur Produktion von Erythrit eingesetzt. Die Produktion erfolgt zur Zeit in einem 500 m^3 großen Reaktor.

description: We have investigated the nature of the antiferromagnetic (AF) phase induced by uniaxial stress sigma in URu2Si2, by performing elastic neutron scattering measurements up to 0.4 GPa. We have found that the AF Bragg-peak intensity shows a clear hysteresis loop with sigma under the zero-stress cooling condition. The result strongly suggests that the sigma-induced AF phase is metastable and separated from the coexisting "hidden ordered" phase by a first-order phase transition. We also present the analyses of the crystalline strain effects, and suggest that the c/a ratio plays an important role in the competition between these two phases.

description: Neurons develop highly stereotypic dendritic arbors that influence establishment of proper connections and integration of information they receive to generate an appropriate output. Morphogenesis of dendrites is coordinated by both cell-intrinsic and extrinsic factors. Recent studies have begun to elucidate how interactions between neurons shape dendrite morphogenesis. However, influence of the substrate upon which neurons grow their dendritic arbors in this process is relatively poorly understood. Here I have used the peripheral sensory neurons of the Drosophila larva that grow dendrites over epithelial cell substrates to gain insights into how interactions with the substrate may influence dendrite development. In this thesis, I present data showing that Basigin, an immunoglobulin superfamily member, has somatodendritic and axonal localization in sensory neurons, and is enriched at cell borders and beneath class IV dendrites in epithelial cells. Loss of function analyses indicate that Basigin is required both in neurons and epithelial cell substrates for proper morphogenesis of the highly complex dendrites of class IV sensory neurons. Reduced innervation of the dendritic field of basigin mutant neurons was observed even at an immature stage, indicating a requirement of Basigin in these neurons for developmental elaboration of dendritic arbors. Structure-function analysis revealed that membrane-tethering of Basigin on the neuronal surface is essential for its function. In addition, a highly conserved tri-basic motif consisting of positively charged residues that may bind cytoskeletal adaptor proteins is required for its function in neurons. Results of genetic interaction analysis suggest that Basigin-mediated regulation of dendrite morphogenesis does not involve Integrin and matrix metalloproteinases, both of which have been implicated in Basigin function in other cellular contexts. I show that Basigin exhibits genetic interaction with Tropomodulin, an actin-capping protein, suggesting that they function in the same molecular pathway in regulating dendrite development. Taken together, data presented in this thesis support a model in which interaction between Basigin on the surfaces of neurons and epithelial cells regulate the underlying cytoskeleton within dendrites to influence their development. Thus, these results identify a novel molecular pathway that may mediate communication between neurons and their substrates that is essential for proper dendrite morphogenesis.

description: A concept was developed by SYLVIS to mitigate energy transition stress using innovative mine reclamation at Alberta coal mines. It involved using municipal biosolids as a soil amendment to develop a short rotation woody biomass plantation. The concept is adaptable, with layers of benefit offering value for mineral mine reclamation and can utilize residuals other than municipal biosolids. Taseko Mines partnered with West Fraser and SYLVIS Environmental to explore the feasibility and benefit of modifying this concept to use pulp residuals from West Fraser’s Cariboo Pulp and Paper mill in Quesnel, BC at Taseko’s Gibraltar mine in McLeese Lake, BC for reclaiming their tailings. The feasibility study was funded by Taseko, West Fraser, and British Columbia’s Clean BC program, representing new research into the adaptability of this residualsbased reclamation system. The Reclamation Feasibility Study was comprised of characterization of mill and mine residuals to ensure suitability as feedstocks in soil fabrication and/or as a soil amendment. A bench-scale soil mixing trial was conducted to determine fabricated mixes that optimized soil quality and characteristics while maximizing the use of priority residuals and meeting regulatory requirements. A willow establishment trial using fabricated soil mixes was designed to determine whether the selected fabricated soils were suitable to establish and sustain willow growth. The use of chemical fertilizer, irrigation water source, and willow variety were also examined. The selected soil was fabricated from tailings and pulp sludge as it maximized the use of priority residuals and produced the greatest willow biomass. Results show chemical fertilizer is not required and collection pond water from Gibraltar is suitable for willow irrigation. Tully Champion and Preble willow varieties were most suited to trial conditions representing operational mine reclamation.

description: Amyotrophic Lateral Sclerosis (ALS) is a neurological disease characterized by the degeneration of upper and lower motor neurons. Genetic studies have revealed that many ALS-associated genes are involved in autophagy, but the role of this pathway in motor neurons remains poorly understood. Here, we use the SOD1G93A mouse model to investigate the role of autophagy in ALS. We find neuronal subtype-specific regulation of autophagy over the course of disease progression. Vulnerable motor neurons form large GABARAPL1-positive autophagosomes that engulf ubiquitinated cargo recognized by the selective autophagy receptor p62. Other motor neurons and interneurons do not engulf cargo within GABARAPL1-positive autophagosomes and instead accumulate somatodendritic aggregates. To investigate whether motor neuron autophagy is protective or detrimental, we generated mice in which the critical autophagy gene Atg7 is specifically disrupted in motor neurons. Phenotypic analysis of these mice revealed that autophagy is dispensable for motor neuron survival but plays a key role in regulating presynaptic structure and function. By crossing these mice to the SOD1G93A mouse model, we find that autophagy inhibition accelerates early neuromuscular denervation and neurological dysfunction. However, loss of autophagy in motor neurons eventually leads to an extension of lifespan, and this is associated with reduced pathology in interneurons and glial cells. These data suggest that vulnerable motor neurons rely on autophagy to maintain neuromuscular innervation early in disease. However, autophagy eventually acts in a non-cell autonomous manner to promote disease spread and neuroinflammation. Our results reveal counteracting roles for motor neuron autophagy early and late in ALS disease progression.

description: It is shown that there are large static black holes for which all curvature invariants are small near the event horizon, yet any object which falls in experiences enormous tidal forces outside the horizon. These black holes are charged and near extremality, and exist in a wide class of theories including string theory. The implications for cosmic censorship and the black hole information puzzle are discussed.

Relations among the DS system, the double Kadomtsev-Petviashvili (KP) system and the Ablowitz-Ladik hierarchy (ALH) are established. The DS hierarchy and the double KP system are equivalent. The ALH is the BT of the DS system in a certain reduction. {From} the BT of coupled DS system we can obtain new coupled derivative nonlinear Schrödinger equations.
