description: Marginal irrigated acreage enrolled in the Conservation Reserve Program (CRP) through 1987 represent less than 2 percent of the 23 million acres enrolled nationwide. Marginal irrigated acreage is irrigated land that results in low net returns because of high energy costs (due to high pump lifts and/or low pump capacities) or low productivity. Most of the enrolled irrigated acreage is in 17 Western States, with 68 percent of it in Nebraska and Texas. This report identifies the extent of marginal irrigated acreage enrolled in the CRP through 1987 and the potential enrollment in the CRP under two rates of enrollment, the historical and half the historical rate. This report also examines why producers would enroll irrigated land in the CRP and estimates cost savings and other benefits to remaining irrigators in Nebraska and Texas over a 40-year period.

description: We present a detailed study of a filtering method based upon Dirac quasi-zero-modes in the adjoint representation. The procedure induces no distortions on configurations which are solutions of the euclidean classical equations of motion. On the other hand, it is very effective in reducing the short-wavelength stochastic noise present in Monte Carlo generated configurations. After testing the performance of the method in various situations, we apply it successfully to study the effect of Monte Carlo dynamics on topological structures like instantons.

description: Die Kombination der baulichen Gegebenheiten, des menschlichen Vermögens, der Zeitbezug und die ideelle Haltung bilden die Grundlage der Architektur von (Johannes Andreas) Jan Brinkman und (Cornelius Leendert) Leen Van der Vlugt in den 1920er und 30er Jahren, bei der über die bauteilorientierte Ebene hinausgedacht wird. Um dies aufzuzeigen, werden drei ihrer Bauwerke konstruktiv und strukturell untersucht. Es zeigt sich, dass das Huis Sonneveld, die Van Nelle Fabrik und das Sommerhaus in Ommen auf einer architektonischen Konzeption mit viel Licht und Luft basiert, welche durch die Schlüsselbegriffe Vernetzung, Entmaterialisierung und Individualisierung belegbar ist. Vor allem Bauteilsysteme und Bewegungsabläufe nehmen einen hohen Stellenwert ein, wodurch in der innen- wie außenräumlichen Raumkonzeption wechselseitige Bezüge entstehen, die verdeutlichen, dass sich diese Architektur von den Ansprüchen reiner Funktionalität abhebt. Die Begründung hierfür findet sich in der sozioökonomisch wie theosophisch geprägten Haltung von Bauherr und Baumeister durch John Stuart Mill und Jiddu Krishnamurti. Das Resultat ist eine Architektur, in der die bauliche Ebene nicht von der Empfindungsebene des Nutzers getrennt wird und diesem dadurch ein Gefühl von persönlicher wie sozialer Freiheit im gebauten Raum zu Teil wird.
description: The combination of the structural conditions, the human capacity, the time reference and the idealistic attitude form the basis of architecture of (Johannes Andreas) Jan Brinkman und (Cornelius Leendert) Leen Van der Vlugt in the 1920s and 30s, thinking beyond the componentoriented level. To demonstrate this, three of their buildings are examined constructively and structurally. It is shown that the Huis Sonneveld, the Van Nelle Factory and the Summer House in Ommen are based on an architectural conception with a lot of light and air, which can be substantiated by the key concepts of networking, dematerialization and individualization. Above all, component systems and movement sequences take on a high significance, whereby reciprocal references arise in the interior as well as exterior spatial conception, which make it clear that this architecture stands apart from the demands of pure functionality. The reason for this can be found in the socio-economically as well as theosophically influenced attitude of client and builder by John Stuart Mill and Jiddu Krishnamurti. The result is an architecture in which the constructional level is not separated from the sensory level of the user, thus giving him a feeling of personal and social freedom in the built space.
Coils, fields and xenon : towards measuring xenon spin precession in a magnetic field for the UCN collaboration
Creators: name: Wienands, Joshua Nikolai
Publisher: name: University of British Columbia
Year: 2016

description: In this thesis I present my work on building a set of magnetic coils for the purpose of performing nuclear magnetic resonance (NMR) on Boltzmann polarized protons in water, and on hyperpolarized ¹²⁹Xe. The coils were designed to be used as a method for testing the degree of polarization achieved in ¹²⁹Xe, and for testing the capability of an in-house developed continuous wave (CW) ultraviolet (UV) laser to drive a 2-photon transition in ¹²⁹Xe. This laser will be used to measure the precession frequency of ¹²⁹Xe in a magnetic field, in order to precisely measure the magnitude of that field. This work is being done for the ultra-cold neutron (UCN) collaboration’s flagship experiment: to measure the neutron electric dipole moment (EDM). Previous neutron EDM experiments have only found an upper limit, and have been limited in precision largely because of systematic errors in the magnetic field strength measurement. These experiments, such as the one performed at Institut Laue-Langevin (ILL), which has given us the current lowest limit, used ¹⁹⁹Hg as a co-magnetometer. The UCN EDM experiment will add ¹²⁹Xe in addition to the ¹⁹⁹Hg, to make a dual co-magnetometer. By using multiple species of atoms in the measurement, systematic effects can be greatly reduced. I have characterized the coils that I built by performing NMR on protons in water. I measured the inhomogeneity in the B₀ field, across the sample container, to be 18.9±0.9 μT. It turns out that the homogeneity of the B₀ field can be improved significantly, and it will likely be necessary to do so in order to perform similar experiments on hyperpolarized ¹²⁹Xe. I also found the T₁ time of water in this setup to be 2.7±0.2 s.

description: Purpose: Research shows that dysphagia impacts quality of life negatively, but the nature of these impacts is not well understood. This review article aims to examine the impacts of dysphagia and its interventions on mealtime-related quality of life, participation, and inclusion for people with dysphagia.Method: The protocol for this scoping review was published in July 2019 and involved a search of five scientific databases using dysphagia and quality of life–related terms.Results: In total, 106 studies were included in this review article. A qualitative metasynthesis demonstrated that dysphagia had various negative impacts on quality of life, particularly in populations with severe dysphagia. Dysphagia interventions had a range of positive impacts on quality of life; however, modifying food texture also had negative impacts. Most studies (n = 95) included adults with acquired dysphagia. Only seven studies included people with lifelong conditions, including cerebral palsy or intellectual disability, and only four studies included children. Almost half of the studies (n = 44) used quantitative instruments, including the Swallowing Quality of Life questionnaire or the Eating Assessment Tool, to measure the impact of dysphagia on quality of life, and few studies used qualitative approaches.Conclusions: There are both positive and negative impacts of dysphagia and dysphagia-related interventions on quality of life, participation, and inclusion. Most research is quantitative and limited to adults with acquired dysphagia. Qualitative and longitudinal studies that include populations with lifelong disability and children are needed to determine how dysphagia and its interventions impact quality of life across conditions and over the life span.

description: We discovered a CBB brake mechanism by a phosphoketolase in cyanobacterium Synechococcus elongatus PCC7942 (SeXPK), under low ATP conditions such as light to dark transitions. SeXPK is inhibited by high level of ATP (~1mM), as its kinetics data shown in Fig 1, Extended Data Fig1, and supplementary table 1. When ATP drops under the transition from light to dark, the XPK deletion mutant continues to fix carbon for ~5 min, while the WT strain reduces carbon fixation immediately (Fig. 2). Isotopic NaH13CO3 feeding experiments showed that the XPK deletion strain fixed more carbon to synthesize hexose phosphates, typically glucose-6-phosphate, glucose-1-phosphate, and fructose-6-phosphate (Fig. 3 and Supplementrary Fig. 1) under transitions from light to dark. This data suggesting that XPK regulates carbon fixation brake by removing the rubisco substrate precursors of RuBP in CBB pathway. We also found that ATP levels of the cell cultures were reduced when cell cultures at high optical densities (Fig. 4 a). In this condition, the carbon incorporation rate is increased by deletion of XPK (Fig. 4 b-e) and the sucrose is synthesized then excreted out of cells into culture medium (Fig. 4 g). The increase of carbon fixation by deletion of SeXPK is mainly resulted in sucrose production (Fig 4. h). However, deletion of SeXPK does not influence carbon release in dark (Fig. 4 f), photosynthesis, and dark respiration (Supplementary Table. 2). We observed the growth differences between the WT and the XPK deletion mutant under different frequency light/dark cylces and analyzed growth rates by imaging their autofluoresence increases in four days (Fig. 5). The detailed experimental processes and methods are descreibed in the Method of the manucript in title "An ATP-sensitive phosphoketolase regulates carbon fixation in cyanobacteria". The raw data for biochemical analyses and physiological studies are presented here. The RNA-seq data of the WT and the XPK deletion mutant is deposited in NCBI GEO DataSets, and the accession number is GSE227397. The cryoEM structures and their maps have been deposited in the Protein Data Bank (PDB) and the Electron Microscopy Data Bank (EMDB) with the accession codes listed in Supplementary Table 3 in the manuscript.

description: Increased agricultural productivity in the Sahel will require widespread diffusion of improved soil- and water-management practices that stimulate growth in a sustainable way. Techniques such as tied-ridges, animal traction, and fertilization can improve productivity but may not be viable unless used together. Improved soil and water management is required to produce a more fertile agronomic environment receptive to new high-yielding crop varieties needed to greatly expand productivity. However, environmental conditions, farmers' resources, inability to make complementary investments that would make such practices profitable, marketing channels, and institutional/policy arrangements constrain adoption of these techniques. Adoption rates can improve if new farming practices enhance soil and water conditions at modest cost, reduce the risk of food and capital loss during poor weather years, and relieve seasonal labor constraints. However, tandem improvements are necessary in input and product markets, rural institutions, and policies to stimulate adoption by creating opportunities and incentives at the farm level.

Cranial shape correlates with diet specialization in northeast Pacific killer whale (Orcinus orca) ecotypes.
Creators: name: Fung, Charissa W.
Publisher: name: University of British Columbia
Year: 2016

description: Resident, transient (Bigg’s), and offshore killer whales (Orcinus orca) live in sympatric and parapatric ranges in the northeast Pacific Ocean. These ecotypes have different vocal repertoires (Ford and Fisher, 1982; Ford, 1991; Yurk, 2002), echolocation use (Barrett-Lennard et al., 1996), foraging strategies (Bigg et al., 1987; Ford et al., 1998; Baird et al., 1992; Deecke et al., 2002; Ford et al., 2011), and sociobiology (Ford and Fisher, 1982; Bigg et al., 1987; Deecke et al., 2000; Baird and Whitehead, 2000; Riesch et al., 2012). Genetic studies corroborate the behavioural evidence that the resident and transient (Bigg’s) populations are reproductively isolated despite the absence of any geographic or temporal barrier (Stevens et al., 1989; Barrett-Lennard, 2000; Hoelzel and Dover, 1991; Morin et al., 2010). The behavioural segregation between the sympatric ecotypes is apparently maintained by cultural mechanisms alone, which is extremely unusual among non-human mammalian species (Barrett-Lennard, 2000; Riesch et al., 2012). These ecotypes also exhibit dramatic resource polymorphisms: resident killer whales feed exclusively on fish, transient (Bigg’s) killer whales primarily hunt marine mammals (Bigg, 1982; Baird et al., 1992, Ford et al., 1998) and offshore killer whales are thought to feed on fishes including Pacific sleeper shark (Somniosus pacificus) (Ford et al., 2011). We do not know if cranial features related to capturing and processing prey have evolved to reflect the dramatic dietary specializations observed in these three ecotypes. The goal of this research was to determine whether there has been divergence of cranial morphology among the three ecotypes. To this end, I measured and compared cranial shape using traditional and geometric morphometrics techniques. I found that transient (Bigg’s) killer whales that bite and tear apart large mammals have more robust cranial skeletons than the piscivorous resident and offshore killer whales that handle smaller prey items. I found that resident and transient (Bigg’s) killer whales are distinguishable based on skull width, rostral width, and mandibular shape, and that offshore killer whales have a more variable morphology that precludes identification based on cranial shape alone.

description: We measure the photoluminescence (PL) lifetime, $τ$, of excitons in colloidal PbSe nanocrystals (NCs) at low temperatures to 270~mK and in high magnetic fields to 15~T. For all NCs (1.3-2.3~nm radii), $τ$ increases sharply below 10~K but saturates by 500~mK. In contrast to the usual picture of well-separated ``bright" and ``dark" exciton states (found, e.g., in CdSe NCs), these dynamics fit remarkably well to a system having two exciton states with comparable - but small - oscillator strengths that are separated by only 300-900 $μ$eV. Importantly, magnetic fields reduce $τ$ below 10~K, consistent with field-induced mixing between the two states. Magnetic circular dichroism studies reveal exciton g-factors from 2-5, and magneto-PL shows $>$10\% circularly polarized emission.

Year: 2010
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Acoustic wave propagation in a fluid with a random assortment of identical cylindrical scatterers is considered. While the leading order correction to the effective wavenumber of the coherent wave is well established at dilute areal density ($n_0 $) of scatterers, in this paper the higher order dependence of the coherent wavenumber on $n_0$ is developed in several directions. Starting from the quasi-crystalline approximation (QCA) a consistent method is described for continuing the Linton and Martin formula, which is second order in $n_0$, to higher orders. Explicit formulas are provided for corrections to the effective wavenumber up to O$(n_0^4)$. Then, using the QCA theory as a basis, generalized self consistent schemes are developed and compared with self consistent schemes using other dynamic effective medium theories. It is shown that the Linton and Martin formula provides a closed self-consistent scheme, unlike some other approaches.

For binary systems we incorporate identity exchange moves in a way that allows to avoid the generation of high energy configurations. Using this modified Minima Hopping method we reexamine the binary Lennard Jones (BLJ) benchmark system with up to 100 atoms and we find a large number of new putative global minima structures.

description: We extend our modeling of the ionization structure of magnetohydrodynamic (MHD) accretion-disk winds, previously applied to Seyfert galaxies, to a population of quasi-stellar-objects (QSOs) of much lower X-ray-to-UV flux ratios, i.e. smaller $α_{\rm ox}$ index, motivated by UV/X-ray ionized absorbers with extremely high outflow velocities in UV-luminous QSOs. We demonstrate that magnetically-driven winds ionized by a spectrum with $α_{\rm ox} \simeq -2$ can produce the charge states responsible for \civ ~and \fexxv/\fexxvi ~absorption in wind regions with corresponding maximum velocities of $v$(\civ) $\lsim 0.1c$ and $v({\rm \fexxv}) \lsim 0.6 c$ (where $c$ is the speed of light) and column densities $N_H \sim 10^{23}-10^{24}$ cm$^{-2}$, in general agreement with observations. In contrast to the conventional radiation-driven wind models, {\it high-velocity flows are always present in our MHD-driven winds} but manifest in the absorption spectra only for $α_{\rm ox} \lsim -2$, as larger $α_{\rm ox}$ values ionize the wind completely out to radii too large to demonstrate the presence of these high velocities. We thus predict increasing velocities of these ionized absorbers with decreasing (steeper) $α_{\rm ox}$, a quantity that emerges as the defining parameter in the kinematics of the AGN UV/X-ray absorbers.

description: We discuss the creation of non-classical light from collective atomic states that are prepared in a ring-shaped lattice. These states are realized by exploiting the strong interaction between atoms in high lying energy levels - so-called Rydberg states - and yield a resource for creating excitations of the electromagnetic field that carry few photons. We characterize the properties of these photonic states showing that they are determined by the interplay between the ring geometry, the structure of the atomic resource states and the collectivity in the photon emission which is controlled by the lattice spacing. The system permits the creation of single photons with well-defined orbital angular momentum and two-photon states that are entangled in orbital angular momentum.

Optimal treatment planning under consideration of patient heterogeneity and preparation lead-time
Creators: name: Skandari, Mohammad Reza
Publisher: name: University of British Columbia
Year: 2016

description: This thesis comprises three chapters with applications of stochastic optimization models to vascular access planning for patients with chronic kidney disease (CKD). Hemodialysis (HD) is the most common treatment for patients with end-stage renal disease, the last stage of CKD. There are two primary types of vascular accesses used for HD, arteriovenous fistula (AVF), and central venous catheter (CVC). An AVF, which is created via a surgical procedure, is often considered the gold standard for delivering HD due to better patient survival and higher quality of life. However, there exists a preparation lead-time for establishing a functional AVF since it takes several months to know whether the surgery was successful, and a majority of AVF surgeries end in failure. In this thesis, we address the question of whether and when to perform AVF surgery on patients with CKD with the aim of finding individualized policies that optimize patient outcomes. In Chapter 2 we focus on vascular access planning for HD dependent patients. Using a continuous-time dynamic programming model and under data-driven assumptions, we establish structural properties of optimal policies that maximize a patient's probability of survival and quality-adjusted life expectancy. We provide further insights for policy makers through our numerical experiments. In Chapter 3 we develop a Monte-Carlo simulation model to address the timing of AVF preparation for progressive CKD patients who have not yet initiated HD. We consider two types of strategies based on approaches suggested in recently published guidelines. We evaluate these strategies over a range of values for each strategy, compare them with respect to different performance metrics (e.g., percentage of patients with an unnecessary AVF creation), and provide policy recommendations. Our simulation results suggest that the timing of AVF referral should be guided by the individual rate of CKD progression. Motivated by our findings in Chapter 3, we develop a dynamic programming model in Chapter 4 that incorporates patient heterogeneity in disease progression when making clinical decisions. We then apply this modeling framework to the case of the AVF preparation timing problem introduced in Chapter 3 and provide recommendations that consider patient heterogeneity in CKD progression.

description: We consider generic curves in R^2, i.e. generic C^1 functions f from S^1 to R^2. We analyze these curves through the persistent homology groups of a filtration induced on S^1 by f. In particular, we consider the question whether these persistent homology groups uniquely characterize f, at least up to re-parameterizations of S^1. We give a partially positive answer to this question. More precisely, we prove that f=goh, where h:S^1-> S^1 is a C^1-diffeomorphism, if and only if the persistent homology groups of sof and sog coincide, for every s belonging to the group Sigma_2 generated by reflections in the coordinate axes. Moreover, for a smaller set of generic functions, we show that f and g are close to each other in the max-norm (up to re-parameterizations) if and only if, for every s belonging to Sigma_2, the persistent Betti numbers functions of sof and sog are close to each other, with respect to a suitable distance.

Just another fan of yours : renegotiating Judy Garland's star status and contemporary fandom
Creators: name: Hulsey, Hilary
Publisher: name: University of British Columbia

description: In popular culture, Judy Garland is most commonly known for her role as Dorothy Gale in The Wizard of Oz (Fleming 1939). She is also concurrently associated with the tragedies of her life, untimely death, and her status as a gay icon. These two labels, “tragic” and “gay icon,” have described Garland’s star status for nearly fifty years in newspaper articles, tertiary texts, and scholarly research. While they are grounded in reputable studies and historical evidence, the labels are seemingly no longer applicable upon observing the types of fans Garland continues to attract posthumously. This thesis aims to uncover the multi-faceted, multi-generational fandom of Garland through an audience reception study of her present fans. Through an exploration of their devoutness, I have discovered key terms involving emotional depth, authentic feelings, and empathy that supplement the publications on Garland from scholars such as Richard Dyer, Janet Staiger, Steven Cohan, and Ann Pellegrini. Ultimately, through the analysis of Garland’s star status and contemporary fandom, this thesis will prove that stars of bygone eras that remain fixtures in popular culture (and by means of a cult following) function as texts that are worthy of analysis as time and culture progresses.

description: Blue phases are networks of disclination lines, which occur in cholesteric liquid crystals near the transition to the isotropic phase. They have recently been used for the new generation of fast switching liquid crystal displays. Here we study numerically the steady states and switching hydrodynamics of blue phase I (BPI) and blue phase II (BPII) cells subjected to an electric field. When the field is on, there are three regimes: for very weak fields (and strong anchoring at the boundaries) the blue phases are almost unaffected, for intermediate fields the disclinations twist (for BPI) and unzip (for BPII), whereas for very large voltages the network dissolves in the bulk of the cell. Interestingly, we find that a BPII cell can recover its original structure when the field is switched off, whereas a BPI cell is found to be trapped more easily into metastable configurations. The kinetic pathways followed during switching on and off entails dramatic reorganisation of the disclination networks. We also discuss the effect of changing the director field anchoring at the boundary planes and of varying the direction of the applied field.

description: Purpose: Cognitive effort is a clinically important facet of linguistic processing that is often overlooked in the assessment and treatment of people with aphasia (PWA). Furthermore, there is a paucity of valid ways to index cognitive effort in PWA. The construct of cognitive effort has been indexed for decades via pupillometry (measurement of pupil dilation and constriction during a cognitive task), yet pupillometry has not been implemented in studies including PWA. In the present study, we tested a novel method for indexing cognitive effort during linguistic processing in people with and without aphasia.Method: Forty control participants and 39 PWA listened to semantically easy and difficult single nouns and looked at images while their pupillary responses were monitored. Mean pupil dilation in response to easy versus difficult nouns was calculated to index cognitive effort.Results: Larger mean pupil dilation values were obtained for difficult compared with easy nouns for both groups.Conclusion: Results provide preliminary evidence that pupillometry can be used to index cognitive effort during linguistic processing of single nouns in people with and without aphasia. Methods for indexing cognitive effort will be a valuable addition to existing assessment methods. Suggestions for further research are offered.
KdV solitons in a cold quark gluon plasma

description: The relativistic heavy ion program developed at RHIC and now at LHC motivated a deeper study of the properties of the quark gluon plasma (QGP) and, in particular, the study of perturbations in this kind of plasma. We are interested on the time evolution of perturbations in the baryon and energy densities. If a localized pulse in baryon density could propagate throughout the QGP for long distances preserving its shape and without loosing localization, this could have interesting consequences for relativistic heavy ion physics and for astrophysics. A mathematical way to proove that this can happen is to derive (under certain conditions) from the hydrodynamical equations of the QGP a Korteveg-de Vries (KdV) equation. The solution of this equation describes the propagation of a KdV soliton. The derivation of the KdV equation depends crucially on the equation of state (EOS) of the QGP. The use of the simple MIT bag model EOS does not lead to KdV solitons. Recently we have developed an EOS for the QGP which includes both perturbative and non-perturbative corrections to the MIT one and is still simple enough to allow for analitycal manipulations. With this EOS we were able to derive a KdV equation for the cold QGP.

description: Collisional de-excitation rates of partially deuterated molecules are different from the fully hydrogenated species because of lowering of symmetry. We compute the collisional (de)excitation rates of ND2H by ground state para-H2, extending the previous results for He- lium. We describe the changes in the potential energy surface of NH3- H2 involved by the pres- ence of two deuterium nuclei. Cross sections are calculated within the full close-coupling ap- proach and augmented with coupled-state calculations. Collisional rate coefficients are given between 5 and 35 K, a range of temperatures which is relevant to cold interstellar conditions. We find that the collisional rates of ND2H by H2 are about one order of magnitude higher than those obtained with Helium as perturber. These results are essential to radiative transfer modelling and will allow to interpret the millimeter and submillimeter detections of ND2H with better constraints than previously.

Electron concentration effects on the Shastry-Sutherland phase stability in Ce_{2-x}Pd_{2+y}In_{1-z} solid solutions

description: The stability of a Shastry-Sutherland ShSu phase as a function of electron concentration is investigated through the field dependence of thermal and magnetic properties of the solid solution Ce_{2-x}Pd_{2+y}In_{1-z} in the antiferromagnetic branch. In these alloys the electronic (holes) variation is realized by increasing $Pd$ concentration. The AF transition T_M decreases from 3.5K to 2.8K as $Pd$ concentration increases from y=0.2 to y=0.4. By applying magnetic field, the ShSu phase is suppressed once the field induced ferromagnetic polarization takes over at a critical field B_{cr} which increases with $Pd$ content. A detailed analysis around the critical point reveals a structure in the maximum of the dM/dB derivative, which is related with incipient steps in the magnetization M(B) as predicted by the theory for the ShSu lattice. The crossing of M(B) isotherms, observed in ShSu prototype compounds, is also analyzed. The effect of $In$ substitution by $Pd$ is interpreted as an increase of the number of 'holes' in the conduction band and results in a unique parameter able to describe the variation of the magnetic properties along the studied range of concentration.
