title: Portrait of Rich County
Creators: name: Thomson, Adrian
Publisher: name: Utah State University
Year: 2021

description: Portrait of Rich County presents the small town of Randolph, Utah in poems describing its wildlife, recreational activities, and the perspectives of citizens in the contemporary rocky mountain west. Special attention to the imagination of the poems’ speaker toward the more dreamlike qualities of Rich County establishes itself throughout, in order to convey a feeling of hope within harsh terrain. This collection examines the theme of salvaging items not often considered, such as rusted junk, ancient houses, or roadside garbage, both in the actions of the speaker and through the act of naming these items upon the page. An over-arching theme, the ever present threat of death in isolation, contrasts the danger, remoteness and shocking weather of Rich County with its moments of beauty, sublimity and respite. In effect, a wider portrait is painted of the whole.
title: Conserving Water Through Modular Planting Design: Water-Wise Templates for Ogden's Residential Front Yard Landscapes
Creators: name: Clements, Jessica
Publisher: name: Utah State University
Year: 2021

description: Due to the arid climate of the Wasatch front and the projected population growth in the next thirty years, water conservation is essential. Consequently, because the landscape consumes 60% of Utah residences’ purified drinking water, water-wise landscaping needs to be a priority. This thesis creates water-wise landscape templates that can be applied to the front yards of Ogden rental properties using a modular planting method. This study determines best practices by researching topics such as water-wise plants for Northern Utah, templates utilized in other areas, modular planting, and existing organizations with similar goals. This results in a user-friendly guide that includes three sections: Research and Relevance, Design, Implementation and Maintenance. Possible water and cost savings are calculated to reveal the untapped potential in converting Ogden’s rental properties to water conserving landscapes. This contributes to the available body of knowledge concerning water-wise landscape education and will help identify simple and accessible ways for application, especially targeted to real estate investors, in order to enhance ecological awareness and create beauty.

description: Quantum computers based on rare-earth-ion-doped crystals show promising properties in terms of scalability and connectivity if single ions can be used as qubits. Through simulations, we investigate gate operations on such qubits and discuss how gate and system parameters affect gate errors, the required frequency bandwidth per qubit, and the risk of instantaneous spectral diffusion (ISD) occurring. Furthermore, we examine how uncertainties in the system parameters affect the gate errors, and how precisely the system needs to be known. We find gate errors for arbitrary single-qubit gates of $2.1\cdot 10^{-4}$ when ISD is not considered and $3.4\cdot 10^{-4}$ when we take heed to minimize it. Additionally, we construct two-qubit gates with errors ranging from $5\cdot 10^{-4} \rightarrow 3\cdot 10^{-3}$ over a broad range of dipole-dipole interaction strengths.

description: Recent observations of the ultra-hot Jupiter WASP-76b have revealed a diversity of atmospheric species. Here we present new high-resolution transit spectroscopy of WASP-76b with GRACES at the Gemini North Observatory, serving as a baseline for the Large and Long Program "Exploring the Diversity of Exoplanet Atmospheres at High Spectral Resolution" (Exoplanets with Gemini Spectroscopy, or ExoGemS for short). With a broad spectral range of $400 - 1050$ nm, these observations allow us to search for a suite of atomic species. We recover absorption features due to neutral sodium (Na I), and report a new detection of the ionized calcium (Ca II) triplet at ~ $850$ nm in the atmosphere of WASP-76b, complementing a previous detection of the Ca II H & K lines. The triplet has line depths of $0.295 \pm 0.034$% at ~ $849.2$ nm, $0.574 \pm 0.041$% at ~ $854.2$ nm, and $0.454 \pm 0.024$% at ~ $866.2$ nm, corresponding to effective radii close to (but within) the planet's Roche radius. These measured line depths are significantly larger than those predicted by model LTE and NLTE spectra obtained on the basis of a pressure-temperature profile computed assuming radiative equilibrium. The discrepancy suggests that the layers probed by our observations are either significantly hotter than predicted by radiative equilibrium and/or in a hydrodynamic state. Our results shed light on the exotic atmosphere of this ultra-hot world, and will inform future analyses from the ExoGemS survey.

Small country, big business? New Zealand as education exporter

description: This paper discusses New Zealand’s role in the global market for tertiary education. The internationalisation and liberalisation of education markets is progressing rapidly in today’s globalising world, as reflected by the incorporation of education as a service into the GATS framework. Through the example of New Zealand as a case study for the internationalisation of education services, the study depicts the way the government is involved in this process. Commodification of sectors traditionally subject to domestic public policy is often associated with a less interventionist state, but our example of education shows that this is not necessarily the case, at least not in the mediumterm: New Zealand’s government rather appears to be an active facilitator of the liberalisation process in education. We review its recent move towards treating education as an international export good and present data on the growth of this industry. The paper concentrates on the particular ways by which New Zealand’s government is trying to facilitate this process of liberalising the education sector.

description: We review different constrained versions of the NMSSM: the fully constrained cNMSSM with universal boundary conditions for gauginos and all soft scalar masses and trilinear couplings, and the NMSSM with soft terms from Gauge Mediated Supersymmetry Breaking. Regarding the fully constrained cNMSSM, after imposing LEP constraints and the correct dark matter relic density, one single parameter is sufficient to describe the entire Higgs and sparticle spectrum of the model, which then contains always a singlino LSP. The NMSSM with soft terms from GMSB is phenomenologically viable if (and only if) the singlet is allowed to couple directly to the messenger sector; then various ranges in parameter space satisfy constraints from colliders and precision observables. Motivations for and phenomenological features of extra U(1)' gauge symmetries are briefly reviewed.

description: In der vorliegenden Studie untersuchen wir, welchen Einfluss die elterliche Arbeitslosigkeit auf den Bildungserfolg von Kindern in Deutschland hat. Wir betrachten Bildungsverläufe vom Zeitpunkt des Übergangs in die mehrgliedrige Sekundarstufe bis ins junge Erwachsenenalter von 23 Jahren. Wir fokussieren insbesondere auf die Frage, ob Kinder von Arbeitslosen im Vergleich zu anderen Personen seltener ein Hochschulstudium beginnen, nehmen aber auch den Besuch des Gymnasiums zu Beginn und Ende der Sekundarschulzeit als Bildungsergebnisse mit in den Blick. Wir verwenden Daten des Sozio-oekonomischen Panels (SOEP). Dem Problem der sozialen Selektivität des Arbeitslosigkeitsrisikos begegnen wir mit einem umfassenden Kontrollvariablenansatz im Rahmen von random effects Modellen. Zusätzlich schätzen wir fixed effects Modelle, in denen wir die Tatsache nutzen, dass die Daten Angaben zu Geschwistern enthalten. Im Ergebnis zeigt sich, dass sowohl bei umfassender Kontrolle von Statusmerkmalen als auch in den Geschwistermodellen ein signifikanter Einfluss von Arbeitslosigkeit auf den Bildungserfolg zu beobachten ist. Allerdings gilt dies nicht für alle betrachteten Bildungsergebnisse und auch nicht für alle Ausprägungen von Arbeitslosigkeit.
Unit determination under the labour code
Creators: name: Jordan, Donald James
Publisher: name: University of British Columbia
Year: 2010

description: The structure of bargaining units and the principles governing their creation have not been the subject of extensive analysis in Canadian labour law. It is the object of this work to canvass the work of the British Columbia Labour Relations Board in this area. The introductory portion of this study focusses on the conceptual alternatives which underlie the process of unit determination and identifies the concerns of the parties to that process. Against this background, the study reviews the process of unit determination as it transpired prior to the passage of the Labour Code of British Columbia, S.B.C. 1973 (2nd Sess.) c. 122 and amendments thereto. Four categories of influential factors are isolated and commented upon. The thesis concludes with an extensive examination of the jurisprudence of the British Columbia Labour Relations Board as it relates to the process of unit determination. Further, an inquiry is made into other areas which are concerned with the structure of bargaining to determine whether there is consistent application of policy. The conclusions reached are that the approach followed by the British Columbia Labour Relations Board is a worthwhile model and is consistent in its isolation of the structure of bargaining as a major factor in industrial unrest.

description: K2-25b is a Neptune-sized exoplanet (3.45 Earth radii) that orbits its M4.5 host with a period of 3.48 days. Due to its membership in the Hyades Cluster, the system has a known age (727 +/- 75 Myr). K2-25b's youth and its similarities with Gl 436b suggested that K2-25b could be undergoing strong atmospheric escape. We observed two transits of K2-25b at Lyman-alpha using HST/STIS in order to search for escaping neutral hydrogen. We were unable to detect an exospheric signature, but placed an upper limit of (R_p/R_s) < 0.56 at 95% confidence by fitting the light curve of the Lyman-alpha red-wing, or < 1.20 in the blue-wing. We reconstructed the intrinsic Lyman-alpha profile of K2-25 to determine its Lyman-alpha flux, and analyzed XMM-Newton observations to determined its X-ray flux. Based on the total X-ray and extreme ultraviolet irradiation of the planet (8763 +/- 1049 erg/s/cm^2), we estimated the maximum energy-limited mass loss rate of K2-25b to be 10.6 x 10^10 g/s (0.56 Earth masses per 1 Gyr), five times larger than the similarly estimated mass loss rate of Gl 436b (2.2 x 10^10 g/s). The photoionization time is about 3 hours, significantly shorter than Gl 436b's 14 hours. A non-detection of a Lyman-alpha transit could suggest K2-25b is not significantly losing its atmosphere, or factors of the system are resulting in the mass loss being unobservable (e.g., atmosphere composition or the system's large high energy flux). Further observations could provide more stringent constraints.

Under mild assumptions, if f: Y --> P^1 is a three-point G-Galois cover defined over C, then the nth higher ramification groups above p for the upper numbering of the (Galois closure of the) extension K/Q vanish, where K is the field of moduli of f.

We show that the combined theory, expanded about its trivial vacuum, is BRST equivalent to a trivial theory, while the theory with a vev for one of the scalars associated with a null direction in the three-algebra is equivalent to a reformulation of maximally supersymmetric 2+1 dimensional Yang-Mills theory in which there a formal SO(8) superconformal invariance.

description: We study a strong coupling expansion of the $ν=1/3$ fractional quantum Hall state away from the Tao-Thouless limit and show that the leading quantum fluctuations lead to an effective spin-1 Hamiltonian that lacks parity symmetry. By analyzing the energetics, discrete symmetries of low-lying excitations, and string order parameters, we demonstrate that the $ν=1/3$ fractional quantum Hall state is adiabatically connected to both Haldane and large-$D$ phases, and is characterized by a string order parameter which is dual to the ordinary one. This result indicates a close relation between (a generalized form of) the Haldane conjecture for spin chains and the fractional quantum Hall effect.

Es werden fünf Dimensionen von Verfestigung unterschieden: Die zeitliche Verstetigung von Armut, die Kumulation von Problemlagen über verschiedene Lebenslagenbereiche hinweg, die sozialstrukturelle Konzentration, die sozialräumliche Segregation und die intergenerationale Transmission von Armut. Für vier dieser fünf Dimensionen kann empirisch gezeigt werden, dass die Verfestigung von Armut die bestimmende Tendenz der Armutsentwicklung in Deutschland seit etwa 20 Jahren darstellt. Diese Tendenz wird immer noch zu wenig beachtet.

description: We give, in Sections 2 and 3, an english translation of: {\it Classes généralisées invariantes}, J. Math. Soc. Japan, 46, 3 (1994), with some improvements and with notations and definitions in accordance with our book: {\it Class Field Theory: from theory to practice}, SMM, Springer-Verlag, $2^{\rm nd}$ corrected printing 2005. We recall, in Section 4, some structure theorems for finite $\mathbb{Z}_p[G]$-modules ($G \simeq \mathbb{Z}/p\,\mathbb{Z}$) obtained in: {\it Sur les $\ell$-classes d'idéaux dans les extensions cycliques relatives de degré premier $\ell$}, Annales de l'Institut Fourier, 23, 3 (1973). Then we recall the algorithm of local normic computations which allows to obtain the order and (potentially) the structure of a $p$-class group in a cyclic extension of degree $p$. In Section 5, we apply this to the study of the structure of relative $p$-class groups of Abelian extensions of prime to $p$ degree, using the Thaine--Ribet--Mazur--Wiles--Kolyvagin "principal theorem", and the notion of "admissible sets of prime numbers" in a cyclic extension of degree $p$, from: {\it Sur la structure des groupes de classes relatives}, Annales de l'Institut Fourier, 43, 1 (1993). In conclusion, we suggest the study, in the same spirit, of some deep invariants attached to the $p$-ramification theory (as dual form of non-ramification theory) and which have become standard in a $p$-adic framework. Since some of these techniques have often been rediscovered, we give a substantial (but certainly incomplete) bibliography which may be used to have a broad view on the subject.

description: A parallel square-root algorithm together with its systolic arrays implementation are proposed for performing the modified extended Kalman filter (MEKF). The proposed parallel square-root algorithm is designed based on the singular value decomposition (SVD) and the Faddeev algorithm, and a very large scale intergration (VLSI) systolic arrays architecture is developed for its implementation. Comparing with other square root Kalman filtering algorithms existing in literature, the proposed method is more numerically stable. Moreover, the new VLSI architecture has very nice parallel and pipelining characteristics in applying the MEKF and achieves higher efficiency. For n-dimensional state vector estimations, the proposed architecture consists of O(2n2) processing elements and uses O((s + 17)n) time-steps for a complete iteration at each instant, in contrast to the complexity of O((s + 6)n3) time-steps for a sequential implementation, where s ≈ log n.
Is H3+ cooling ever important in primordial gas?

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Studies of the formation of metal-free Population III stars usually focus primarily on the role played by H2 cooling, on account of its large chemical abundance relative to other possible molecular or ionic coolants. However, while H2 is generally the most important coolant at low gas densities, it is not an effective coolant at high gas densities, owing to the low critical density at which it reaches local thermodynamic equilibrium (LTE) and to the large opacities that develop in its emission lines. It is therefore possible that emission from other chemical species may play an important role in cooling high density primordial gas. A particularly interesting candidate is the H3+ molecular ion. This ion has an LTE cooling rate that is roughly a billion times larger than that of H2, and unlike other primordial molecular ions such as H2+ or HeH+, it is not easily removed from the gas by collisions with H or H2. It is already known to be an important coolant in at least one astrophysical context -- the upper atmospheres of gas giants -- but its role in the cooling of primordial gas has received little previous study. In this paper, we investigate the potential importance of H3+ cooling in primordial gas using a newly-developed H3+ cooling function and the most detailed model of primordial chemistry published to date. We show that although H3+ is, in most circumstances, the third most important coolant in dense primordial gas (after H2 and HD), it is nevertheless unimportant, as it contributes no more than a few percent of the total cooling. We also show that in gas irradiated by a sufficiently strong flux of cosmic rays or X-rays, H3+ can become the dominant coolant in the gas, although the size of the flux required renders this scenario unlikely to occur.

Procedural safeguards in the administrative process
Creators: name: Parup, Mats Stefan
Publisher: name: University of British Columbia
Year: 2010

description: Throughout the common law countries studies and investigations have been carried out to reform the procedure used by administrative tribunals. The procedural rules to which, tribunals in British. Columbia must adhere are found in the common law rules of natural justice and in the tribunals' establishing statutes. This system has been severely criticized as it is inconsistent and unpredictable. There is no consensus amongst the common law jurisdictions as to which solution to the problem of procedural safeguards in the administrative process is most preferable. The competing interests; protection of the public from unfair government actions, and the efficiency of the administration, are the reasons for this lack of consensus. It is the thesis of this essay that procedural reform is needed in British Columbia. Therefore, British Columbia would benefit from a minimum administrative procedure act applicable to all administrative tribunals' adjudicative functions. The method used to establish this thesis was to research the present situation in British Columbia. As a background to this, a description of the common law rules of natural justice and a study of the procedural rules of three provincial tribunals enacted by the Legislature are given. This essay continues with a description of the solutions used in Ontario and in the United States where minimum procedure rules have been enacted, applicable, to most administrative tribunals. After considering these different solutions, along with, the investigations of law reform reports from various common law jurisdictions, it has been concluded that certain fundamental procedural safeguards should be enacted by way of an administrative procedure act. The main argument for this is that such, an act would serve an educational purpose by informing both, administrators and the public of the procedural rules. As the suggested procedural rules are very fundamental, it is also concluded that it is necessary to carry out further investigations into each tribunal. In this way, more detailed procedural rules could be enacted, applicable to a specific tribunal, if deemed, necessary. In summary, the conclusion of this thesis is that a minimum administrative procedure act will fill an educational purpose and, at the same time, might help to achieve a more consistent, predictable administration with regard to procedure. It might also work as a catalyst by promoting further studies into the procedural aspect of the administrative process.

description: Chemical reactions involving radical-ion pairs are ubiquitous in biology, since not only are they at the basis of the photosynthetic reaction chain, but are also assumed to underlie the biochemical magnetic compass used by avian species for navigation. Recent experiments with magnetic-sensitive radical-ion pair reactions provided strong evidence for the radical-ion-pair magnetoreception mechanism, verifying the expected magnetic sensitivities and chemical product yield changes. It is here shown that the theoretical description of radical-ion-pair reactions used since the 70's cannot explain the observed data, because it is based on phenomenological equations masking quantum coherence effects. The fundamental density matrix equation derived here from basic quantum measurement theory considerations naturally incorporates the quantum Zeno effect and readily explains recent experimental observations on low- and high-magnetic-field radical-ion-pair reactions.

description: Parallel processing systems with cache or local memory in the memory hierarchies have become very common. These systems have large-size cache or local memory in each processor and usually employ copy-back protocol for the cache coherence. In such systems, a problem called "cache or local memory thrashing" may arise in executions of parallel programs, when the data unnecessarily moves back and forth between the caches or local memories in different processors. The techniques associated with parallel compilers to solve the problem are not completely developed. In this paper we present an approach to eliminate unnecessary data moving between the caches or local memories for nested parallel loops. This approach is based on relations between array element accesses and enclosed loop indexes in the nested parallel loops. The relations can be used to assign processors to execute the appropriate iterations for parallel loops in the loop nests withrespect to the data in their caches or local memories. An algorithm to calculate the correct iteration of the parallel loop in terms of loop indexes of the previous iterations executed in the processor is presented in the paper, even though hereis more than one subscript expression of the same array variable in the loop. This method benefits parallel code with nested loop constructs in a wide range of applications, in which the array elements are repeatedly referenced in the parallel loops. The experimental results show that the technique is extremely effective capable of achieving double speedups over application programs such as Linpack benchmarks.

description: We clarify and study our previous observation that, under a compactification with boundaries or orbifolding, vacuum expectation value of a bulk scalar field can have different extra-dimensional wave-function profile from that of the lowest Kaluza-Klein mode of its quantum fluctuation, under presence of boundary-localized potentials which would be necessarily generated through renormalization group running. For concreteness, we analyze the Universal Extra Dimension model compactified on orbifold $S^1/Z_2$, with brane-localized Higgs potentials at the orbifold fixed points. We compute the Kaluza-Klein expansion of the Higgs and gauge bosons in an $R_ξ$-like gauge by treating the brane-localized potential as a small perturbation. We also check that the $ρ$ parameter is not altered by the brane localized potential.

description: In this paper, we describe certain techniques for mapping the modified extended Kalman filter (MEKF) onto systolic array processors. First, we introduce a square-root algorithm based on the singular value decomposition (SVD) for the Kalman filter. Then, we develop a VLSI architecture of the systolic array type for its implementation. Compared with other existing square-root Kalman filtering algorithms our new design is numerically more stable and has nicer parallel and pipelining characteristics when it is applied to the MEKF. Moreover, it achieves higher efficiency. For n-dimensional state vector estimations, the proposed architecture consists of O(3/2n2) processing elements and completes an iteration in time O((s + 8)n), in contrast to the time complexity of O((s + 3)n3) for a sequential implementation, where s ≈ log n.

description: We write out the generic Dirac neutrino mass operator which possesses the Friedberg-Lee (FL) symmetry and find that its corresponding neutrino mass matrix is asymmetric. Following a simple way to break the FL symmetry, we calculate the neutrino mass eigenvalues and show that the resultant neutrino mixing pattern is nearly tri-bimaximal. Imposing the Hermitian condition on the neutrino mass matrix, we also show that the simplified ansatz is consistent with current experimental data and favors the normal neutrino mass hierarchy.

description: La cartographie de l’occupation du sol permet d’appréhender la dynamique spatiale et les changements intervenus dans le temps. En utilisant les outils de la télédétection spatiale, l’étude a abouti à la détection, à l’identification de la nature, à la quantification des surfaces affectées et à la caractérisation de l’organisation de l’espace polarisé par l’université.

L’étude s’appuie sur la détection des changements de l’occupation du sol par traitement et croisement d’images classées au préalable sur trois périodes : 1980-1990, 1990-2005 et 2005-2020.

L’analyse de l’évolution des unités d’occupation du sol se fonde d’abord sur les modifications observées sur ces différentes unités, c’est-à-dire les changements intervenus sur les catégories identiques. Ensuite, nous analysons la reconversion des unités d’occupation du sol avec le passage d’une catégorie distincte à une ou d’autres. Enfin, les classes constantes, n’ayant subi aucun changement d’usage durant l’échelle temporelle choisie ont aussi été relevées. Ces changements spatio-temporels ont fait l’objet d’une évaluation et d’une cartographie diachronique. Nous notons une forte corrélation entre l’implantation de l’université, le développement du front urbain et la régression des espaces agricoles.

Nonuniform mixing

description: Fluid mixing usually involves the interplay between advection and diffusion, which together cause any initial distribution of passive scalar to homogenize and ultimately reach a uniform state. However, this scenario only holds when the velocity field is nondivergent and has no normal component to the boundary. If either condition is unmet, such as for active particles in a bounded region, floating particles, or for filters, then the ultimate state after a long time is not uniform, and may be time dependent. We show that in those cases of nonuniform mixing it is preferable to characterize the degree of mixing in terms of an f-divergence, which is a generalization of relative entropy, or to use the $L^1$ norm. Unlike concentration variance ($L^2$ norm), the f-divergence and $L^1$ norm always decay monotonically, even for nonuniform mixing, which facilitates measuring the rate of mixing. We show by an example that flows that mix well for the nonuniform case can be drastically different from efficient uniformly mixing flows.

description: In response to the interest to re-use Palapa B2R satellite nearing its End of Life (EOL) time, an idea to incline the satellite orbit in order to cover a new region has emerged in the recent years. As a prolate dual-spin vehicle, Palapa B2R has to be stabilized against its internal energy dissipation effect. This work is focused on analyzing the dynamics of the reusable satellite in its inclined orbit. The study discusses in particular the stability of the prolate dual-spin satellite under the effect of perturbed field of gravitation due to the inclination of its elliptical orbit. Palapa B2R physical data was substituted into the dual-spin's equation of motion. The coefficient of zonal harmonics J2 was induced into the gravity-gradient moment term that affects the satellite attitude. The satellite's motion and attitude were then simulated in the perturbed gravitational field by J2, with the variation of orbit's eccentricity and inclination. The analysis of the satellite dynamics and its stability was conducted for designing a control system for the vehicle in its new inclined orbit.

Composite anyon coding and the initialization of a topological quantum computer

Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)

description: Schemes for topological quantum computation are usually based on the assumption that the system is initially prepared in a specific state. In practice, this state preparation is expected to be challenging as it involves non-topological operations which heavily depend on the experimental realization and are not naturally robust against noise. Here we show that this assumption can be relaxed by using composite anyons: starting from an unknown state with reasonable physical properties, it is possible to efficiently distill suitable initial states for computation purely by braiding. This is achieved by encoding logical information in a subsystem code with gauge system corresponding to the internal degrees of freedom of composite objects.

description: The Cherenkov Telescope Array (CTA) will be the next generation very-high-energy gamma-ray observatory. CTA is expected to provide substantial improvement in accuracy and sensitivity with respect to existing instruments thanks to a tenfold increase in the number of telescopes and their state-of-the-art design. Detailed Monte Carlo simulations are used to further optimise the number of telescopes and the array layout, and to estimate the observatory performance using updated models of the selected telescope designs. These studies are presented in this contribution for the two CTA stations located on the island of La Palma (Spain) and near Paranal (Chile) and for different operation and observation conditions.

description: The longest common subsequence problem is to find the longest common subsequence of two given strings. Based on exploiting nice properties of this problem, we proposed a parallel algorithm for finding the longest common subsequence of two strings of length m and n (with m ≤ n), which requires O(log2 m + log(n)) time and mn / log(m) processors on CREW-PRAM. Our algorithm is faster than all existing CREW-PRAM algorithms for this problem.
