Eco-evolutionary perspective on life-history traits with special emphasis on seed dormancy and its genetic basis of adaptation in conifers
Creators: name: Liu, Yang
Publisher: name: University of British Columbia
Year: 2016

description: Life-history traits, known as fitness components, are related to the timing and success of development, reproduction, and senescence throughout the life cycle. Selection in variable environments may favor plants to defer germination until suitable conditions occur. Seed dormancy is an innate constraint on germination timing and prevents germination during periods that are ephemerally favorable. The timing of seed germination is the earliest life-history trait that is expressed and sets the context for the traits that follow. As such, seed dormancy may be construed as an adaptation for survival during bad seasons and can exert cascading selective pressures on subsequent life stages. Seed size is another important life-history trait linking the ecology of reproduction and seedling establishment with that of vegetative growth. As the two traits are, at modulations, regulated by hormone signaling cascades, evolve under correlated selective pressures, and exhibit co-varying phenotypes, this dissertation intended to elucidate their eco-evolutionary dynamics and possible genetic basis of adaptation. From an eco-evolutionary perspective, I demonstrated that dynamic climatic variables rather than constant geographic variables are the true environmental driving forces in seed dormancy and size variations in Pinus contorta Dougl. Evapotranspiration and precipitation in the plant-to-seed transition are the most critical climatic variables for seed dormancy and size variations, respectively. Unlike random temperature fluctuations between generations, wide temperature shifts considerably alter population structures and accelerate life-history evolution. Regarding the genetic basis of adaptation, environmental cues trigger different seed-set programming in Picea glauca and Arabidopsis by employing lineage-specific and deeply conserved microRNAs at different expression levels, respectively, to entrain phenotypical variations, such as dormancy intensities. Our findings additionally point to auxin as a key player that likely works in conjunction with the ABA and GA signal pathways previously investigated in mechanisms underpinning the seed-to-plant transition by chilling in Picea glauca seeds. This dissertation increases our understanding of plant evolution and persistence in the context of climate change and provides fundamental insight for understanding how microRNAs are at play in seed-set programs to regulate phenotypes, how winter chilling contributes to the timing of phenology, and how conifer life histories may develop under new climate scenarios.

Arbitrage Pricing Theory
linear regression

description: This dissertation consists of two parts. The first part introduces a neural network approach that is used to forecast the conditional probability density function of asset returns. The model is unified with the idea of Arbitrage Pricing Theory (APT). In the second part, an algorithm called "individualized semi-linear regression" is discussed. The algorithm is an improvement of a linear regression, but slope and intercept may depend non-linearly on an arbitrary amount of exogenous variables.

description: In this paper we study geodesic mappings of $n$-dimensional surfaces of revolution. From the general theory of geodesic mappings of equidistant spaces we specialize to surfaces of revolution and apply the obtained formulas to the case of rotational ellipsoids. We prove that such $n$-dimensional ellipsoids admit non trivial smooth geodesic deformations onto $n$-dimensional surfaces of revolution, which are generally of a different type.

description: In non-central collisions between ultra-relativistic heavy ions, the freeze-out distribution is anisotropic, and its major longitudinal axis may be tilted away from the beam direction. The shape and orientation of this distribution are particularly interesting, as they provide a snapshot of the evolving source and reflect the space-time aspect of anisotropic flow. Experimentally, this information is extracted by measuring pion HBT radii as a function of angle with respect to the reaction plane. Existing formulae relating the oscillations of the radii and the freezeout anisotropy are in principle only valid for Gaussian sources with no collective flow. With a realistic transport model of the collision, which generates flow and non-Gaussian sources, we find that these formulae approximately reflect the anisotropy of the freezeout distribution.

description: A detector material or configuration that can provide an unambiguous indication of neutron capture can substantially reduce random coincidence backgrounds in antineutrino detection and capture-gated neutron spectrometry applications. Here we investigate the performance of such a material, a composite of plastic scintillator and $^6$Li$_6^{nat}$Gd$(^{10}$BO$_{3})_{3}$:Ce (LGB) crystal shards of ~1 mm dimension and comprising 1% of the detector by mass. While it is found that the optical propagation properties of this material as currently fabricated are only marginally acceptable for antineutrino detection, its neutron capture identification ability is encouraging.

Dissociating memory accessibility and precision in forgetting [ Registered Report Stage 1 - Protocol]

Subjects: Psychology and Cognitive Sciences not elsewhere classified

description: Forgetting involves
the loss of information over time. While previous research has focussed on the
rate of information loss, we know less about the form this loss takes. For
example, are memory representations remembered with less precision, or do they
instead become less accessible? Here we use ‘precision’ measures of memory, and
probabilistic mixture models, to investigate the loss of both precision and
accessibility of word-location associations over time. Importantly, we are able
to directly compare these two measures by converting precision and
accessibility into a common scale – information entropy. Using online testing,
we will assess the extent to which forgetting is driven by a loss in either
precision or accessibility. Further, we will assess how forgetting is modulated
by shared content. Does learning multiple similar experiences decrease
information loss for either precision or accessibility?

description: The Q-cycle mechanism plays an important role in the conversion of the redox energy into the energy of the proton electrochemical gradient across the biomembrane. The bifurcated electron transfer reaction, which is built into this mechanism, recycles one electron, thus, allowing to translocate two protons per one electron moving to the high-potential redox chain. We study a kinetic model of the Q-cycle mechanism in an artificial system which mimics the bf complex of plants and cyanobacteria in the regime of ferredoxin-dependent cyclic electron flow. Using methods of condensed matter physics, we derive a set of master equations and describe a time sequence of electron and proton transfer reactions in the complex. We find energetic conditions when the bifurcation of the electron pathways at the positive side of the membrane occurs naturally, without any additional gates. For reasonable parameter values, we show that this system is able to translocate more than 1.8 protons, on average, per one electron, with a thermodynamic efficiency of the order of 32% or higher.

We give a computer-free proof of the following result by Currie: square-free circular words over the ternary alphabet exist for all lengths $l$ except for 5, 7, 9, 10, 14, and 17. Our proof reveals an interesting connection between ternary square-free circular words and closed walks in the $K_{3{,}3}$ graph. In addition, our proof implies an exponential lower bound on the number of such circular words of length $l$ and allows one to list all lengths $l$ for which such a circular word is unique up to isomorphism.

description: Nonthermal scaling phenomena can exhibit a characteristic dependence on the dimensionality d of space. For d=3 and 4 we simulate a relativistic scalar field theory on a lattice and compute turbulent scaling exponents. We recover Kolmogorov or weak wave-turbulence in the perturbative high-momentum regime, where it exhibits the scaling exponent kappa_w = d - 3/2. In the nonperturbative infrared regime, we find a different scaling exponent kappa_s = 4 (5) for d=3 (4), which is in agreement with the recently predicted anomalously large values kappa_s = d + 1 of strong turbulence. We show how the latter can be seen to characterize stationary transport of a conserved effective particle number.

Musical borrowing in the works of Caroline Shaw
Creators: name: Wilson, John
Publisher: name: No Publisher Supplied
Year: 2021

description: Caroline Shaw’s compositions resonate with audiences and critics alike. She was the youngest recipient of the Pulitzer Prize for Music in 2013 for Partita for 8 Voices, and her other works have been performed by a litany of exemplary musicians and ensembles. Many of Shaw’s works use or respond to preexisting material but do so to varying degrees. Of her sixteen self-published works, twelve engage with preexistent compositions. This study addresses the manner in which Shaw utilizes borrowed material and the resulting expressive effect that is achieved through this borrowing. Four of Shaw’s pieces were selected for analysis: Blueprint (2016), Entr’acte (2011), both works for string quartet, Gustave Le Gray (2012), written for piano, and To the Hands (2016), written for choir and string ensemble. While composers can integrate borrowed material in a wide variety of ways, a tension exists between newly composed music and passages that originate from other sources. This study describes how certain motivic and formal methods impact this tension. Additionally, I focus on how unity and large-scale coherence is affected by the presence of borrowed material.
Mechanical strain bioreactor design and assessment for culture of human airway smooth muscle
Creators: name: Cavers, Andrew
Publisher: name: University of British Columbia
Year: 2016

description: Bioreactors capable of subjecting cells and tissues to time-varying mechanical strain are one aspect of simulating in vivo conditions. A bioreactor to impart arbitrary strain waveforms on cells or tissue scaffolds for loading conditions found in the airway was designed and developed and, in the process, it was determined that there are sources of experimental error which could invalidate bioreactor experiments if not properly mitigated. Without effective design and validation, bioreactors can impart significantly different stimuli than the assumed experimental conditions. Cyclic strain is thought to play a role in airway remodeling by mediating cytoskeletal contraction of the airway smooth muscle. In vitro experiments have demonstrated varying changes to the cytoskeleton depending on experimental conditions. Based on literature review, the strain waveform, magnitude, mechanical properties of the substrate, and anisotropy of the strain stimulus may all affect airway smooth muscle (ASM) differentiation. A bioreactor capable of imparting a broad range of strain stimulus was developed using stepper motors as actuators to allow open-loop control. Any changes in the cells subjected to cyclic strain in these bioreactors would be assumed to correlate with cyclic strain, but a poorly designed bioreactor could introduce confounding experimental stimuli which could easily invalidate the experiment. Heat generated by the actuators can overheat the cell cultures. Vibration might alter the cytoskeletal response. Strain response across the substrate can drastically vary from modeling predictions depending on the loading conditions and how the substrate has been constrained. Methods of mitigating heat generation and transfer were developed. The vibrations emitted by the two stepper motor options were evaluated. A method of mapping the substrate was developed such that nonplanar strains across the substrate surface could be characterized to validate the experimental conditions prior to testing. Finally, ASM cells were subjected to cyclic and static strain on PDMS substrates and cell realignment evaluated. Cells were noted to realign in the cyclic strain tests, as has been reported in several earlier publications, but also realigned under static strain conditions. The bioreactor design objectives were met.

description: [Objectives] To evaluate the pollution status of antibiotics in the soil of vegetable bases in Yangling District. [Methods] The contents of 19 antibiotics in 4 categories of quinolones, tetracyclines, sulfonamides and macrolides in soil samples from 20 bases were detected and analyzed using HPLC-MS/MS. [Results] The quinolones, sulfonamides and tetracyclines were all detected in 100% of soil samples, and the detection rate of macrolides was 62%. The average contents of the four antibiotics from high to low were quinolones (51.76 μg/kg) >tetracyclines (12.77 μg/kg)> sulfonamides (1.14 μg/kg) >macrolides (0.28 μg/kg), and norfloxacin, oxytetracycline, sulfamethazine and erythromycin were the main contents, respectively. According to the trigger value of ecological toxic effect of antibiotics in soil (100 μg/kg) proposed by the Steering Committee of the International Coordinating Committee for Veterinary Medicine (VICH), the contents of the four classes of antibiotics in the soil of the study area were all lower than the trigger value, indicating a small ecological risk. [Conclusions] Compared with other domestic research reports, the vegetable bases in this study area are also at a relatively low level of antibiotic pollution.

description: When approaching the design of a multipole magnet, such as a dipole, quadrupole, sextupole, and so on, it is highly advantageous to initiate the process by establishing the fundamental parameters. These parameters include conductor size, current density, inner and outer radius of the iron yoke, and more. This preliminary dimensioning enables the acquisition of the necessary specifications for the design. Within this report, analytical expressions for the magnetic field, Lorentz forces, and stored energy of multipole magnets with the cos(nθ) and sector coil configurations, both with and without the presence of an iron yoke, are derived. These derivations are based on the vector potential of a current line.

description: We study a brane configuration of D4-branes and NS5-branes in weakly coupled type IIA string theory, which describes in a particular limit d=4 N=1 SU(N+p) supersymmetric QCD with 2N flavors and a quartic superpotential. We describe the geometric realization of the supersymmetric vacuum structure of this gauge theory. We focus on the confining vacua of the gauge theory, whose holographic description is given by the MQCD brane configuration in the near-horizon geometry of N D4-branes. This description, which gives an embedding of MQCD into a field theory decoupled from gravity, is valid for 1 << p << N, in the limit of large five dimensional `t Hooft couplings for the color and flavor groups. We analyze various properties of the theory in this limit, such as the spectrum of mesons, the finite temperature behavior, and the quark-anti-quark potential. We also discuss the same brane configuration on a circle, where it gives a geometric description of the moduli space of the Klebanov-Strassler cascading theory, and some non-supersymmetric generalizations.

(Un)Becoming teacher of school-based Aboriginal education : early career teachers, teacher identity, and Aboriginal education across institutions
Creators: name: Madden, Brooke
Publisher: name: University of British Columbia
Year: 2016

description: This research explores the experiences and perceptions of nine Aboriginal and ally early career teachers (1-5 years experience) who have completed university coursework and/or extended professional development on the topic of Aboriginal education. The inquiry places focus on how targeted teacher education, and transitions into educational work settings, shape teacher identity and practice. Over an eight-month period, teachers participated in a series of three or four individual, semi-structured interviews on topics related to professional identity and engagement in Aboriginal education across institutions. Data fragments elicited from the research reveal ongoing, relational processes of momentarily occupying, exceeding, resisting, and/or reforming subject positions of teacher made available through discourse. The fragments are used to identify and trace significant forces that direct how participants become, and become undone as, teachers of school-based Aboriginal education. Analysis concentrates on four key relationships between teachers and sources of knowledge about Aboriginal education that formed, reinforced, and challenged teachers’ emerging professional identities and associated practices as they navigated Faculties of Education, schools, and areas between (e.g., teaching practicum). They include: (un)becoming teacher and a) school-based sources of Aboriginality, b) pedagogical pathways for Aboriginal education with/in teacher education, c) significant place, and d) supports used for engaging Aboriginal education. Contributions are made to the fields of teacher education, Aboriginal education, and decolonizing education and research. The research reveals the benefits and difficulties that coursework and professional development afford in preparing, and providing ongoing assistance to, teachers who foreground Aboriginal content and approaches. Learning from teachers’ processes, preparedness, and priorities enhances understanding about identity negotiation and movement of knowledge-practice across institutions. Further, theory building presents a decolonizing methodology for analyzing the construction of teacher identity that accounts for teachers’ complex and shifting positions beyond the binary opposition Aboriginal/non-Aboriginal. A decolonizing theory of (un)becoming teacher of Aboriginal education, alongside early career teachers’ recommendations to improve university and school-based Aboriginal education, hold potential to shift Aboriginal education research beyond a discourse of transformation/resistance. This opens space to reconfigure Aboriginal education and teacher education, as well as subject positions therein, to support the needs and prerogatives of Aboriginal students and communities.

description: Recent advancements in mobile systems have led to a rapid proliferation of smart phones and smart devices into our daily lives. This has given rise to a plethora of new services and applications for commercial businesses as well as personal end user consumption. Moreover, the rate at which mobile Internet data is consumed has also increased many-fold in the recent years. Therefore, in order to optimally serve mobile data consumers as well as improve the underlying system performance, understanding and characterizing mobile traffic data becomes essential. In the recent past, mobile networking domain has witnessed several technological innovations including cloudification and virtualization of radio access networks (RAN), advanced resource orchestration via network slicing, massive MIMO antennas, millimeter wave etc. These technological advancements, however, present a paradigm shift from the traditional cellular networks and bring a higher complexity in the management and orchestration of mobile networks due to an increased number of decision variables. Therefore, it becomes important to develop efficient, scalable, traffic-aware solutions for the optimization of mobile network performance. In this thesis, we take a step forward towards mobile network data analysis and network performance optimization. We start by experimenting with a nationwide traffic dataset and build our understanding of mobile traffic usage characteristics at the services (i.e., mobile apps) level. We derive the correlation between service usage and the underlying spatial demographic features. Further, using a data-driven approach, we solve the problem of network resource orchestration in the virtualized RAN (vRAN) setting. We propose a distributed and scalable heuristic solution, GreenRAN, to minimize the overall vRAN energy consumption. A major factor limiting this traffic-driven analytics research is the scarce availability of real-world networking datasets. Access to these datasets is generally restricted either due to the challenges involved in large-scale database access management or due to the privacy issues. To lower this dataset access barrier, we develop a tool, MTGAN, for generating synthetic high-fidelity mobile traffic datasets. Our synthetic traffic generator is a deep neural network based on Conditional Generative Adversarial Networks. Finally, we also study and compare different state-of-the-art mechanisms for privacy preserving data publication. We develop a metric, STRAP, to evaluate user privacy provided by different privacy preserving mechanisms and compare them under a common measure of privacy as determined by STRAP.

description: The intergalactic medium was not completely reionized until approximately a billion years after the Big Bang, as revealed by observations of quasars with redshifts of less than 6.5. It has been difficult to probe to higher redshifts, however, because quasars have historically been identified in optical surveys, which are insensitive to sources at redshifts exceeding 6.5. Here we report observations of a quasar (ULAS J112001.48+064124.3) at a redshift of 7.085, which is 0.77 billion years after the Big Bang. ULAS J1120+0461 had a luminosity of 6.3x10^13 L_Sun and hosted a black hole with a mass of 2x10^9 M_Sun (where L_Sun and M_Sun are the luminosity and mass of the Sun). The measured radius of the ionized near zone around ULAS J1120+0641 is 1.9 megaparsecs, a factor of three smaller than typical for quasars at redshifts between 6.0 and 6.4. The near zone transmission profile is consistent with a Ly alpha damping wing, suggesting that the neutral fraction of the intergalactic medium in front of ULAS J1120+0641 exceeded 0.1.

description: The quasar ULAS J1120+0641 at redshift z=7.085 has a highly ionised near zone which is smaller than those around quasars of similar luminosity at z~6. The spectrum also exhibits evidence for a damping wing extending redward of the systemic Lya redshift. We use radiative transfer simulations in a cosmological context to investigate the implications for the ionisation state of the inhomogeneous IGM surrounding this quasar. Our simulations show that the transmission profile is consistent with an IGM in the vicinity of the quasar with a volume averaged HI fraction of f_HI>0.1 and that ULAS J1120+0641 has been bright for 10^6--10^7 yr. The observed spectrum is also consistent with smaller IGM neutral fractions, f_HI ~ 10^-3--10-4, if a damped Lya system in an otherwise highly ionised IGM lies within 5 proper Mpc of the quasar. This is, however, predicted to occur in only ~5 per cent of our simulated sight-lines for a bright phase of 10^6--10^7 yr. Unless ULAS J1120+0641 grows during a previous optically obscured phase, the low age inferred for the quasar adds to the theoretical challenge of forming a 2x10^9 M_sol black hole at this high redshift.

description: We analyze the avalanche size distribution of the Abelian Manna model on two different fractal lattices with the same dimension d_g=ln(3)/ln(2), with the aim to probe for scaling behavior and to study the systematic dependence of the critical exponents on the dimension and structure of the lattices. We show that the scaling law D(2-tau)=d_w generalizes the corresponding scaling law on regular lattices, in particular hypercubes, where d_w=2. Furthermore, we observe that the lattice dimension d_g, the fractal dimension of the random walk on the lattice d_w, and the critical exponent D, form a plane in 3D parameter space, i.e. they obey the linear relationship D=0.632(3) d_g + 0.98(1) d_w - 0.49(3).

Delafossites

description: This work proposes techniques to access physical properties at intermediate temperatures. These methods include both numerical and analytic ones. The former ones operate within the DMRG aiming to characterize a system at finite temperature by a set of states. The latter ones are applied to a density of states believed to describe the delafossites. These materials have revealed a behavior at intermediate temperatures resembling a Fermi liquid one which is examined with the proposed methods.

description: Excerpts from the report: Potatoes that reach the consumer in their whole raw form are prepared for market through a series of processes, usually including cleaning, sorting, sizing, and packaging. This preparation is accomplished in potato packinghouses located in the production areas and in the heavily populated consuming centers of the country. This study was undertaken to develop guidelines for planning potato packinghouse layouts that will allow more efficient, and flexible operations. Factors to be considered in layout planning are noted, and three example layouts have been prepared. Methods, equipment, and facilities used in large and small commercial potato packinghouses in the Red River Valley area were studied during the development of these layouts. Processes and equipment known to be used in packing plants in other areas of the United States are also included. Many of the operations and facilities may be considered typical of the industry at this time. However, the example layouts emphasize more mechanization of material handling in the plant than is commonly practiced by the industry.

Thermalization of quark-gluon matter with the elastic scattering of gqq, gqqbar and gqbarqbar
Creators: name: Xu, Xiao-Ming

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The elastic scattering of gqq, gqqbar and gqbarqbar and the thermalization of quark-gluon matter are studied. According to Feynman diagrams at the tree level, squared amplitudes for the elastic gqq scattering and the elastic gqqbar scattering are derived in perturbative QCD. Transport equations including the squared amplitudes for the elastic gqq, gqqbar and gqbarqbar scattering are established. Corresponding to anisotropic gluon and quark distributions created in central Au-Au collisions at RHIC, solutions of the transport equations show that thermalization time of quark matter can be shortened by the elastic gqq, gqqbar and gqbarqbar scattering.

description: This document describes the verification process of structural performance of the double- walled copper-steel cryogenic chamber of the ASTAROTH (All Sensitive crysTal ARray with lOw THreshold) experiment and the evaluation of the stresses generated near the thermal bridge connecting the inner and outer wall. The chamber consists of an external AISI 316L stainless steel dewar and an inner double-walled OF (Oxygen Free) copper dewar connected to an AISI 316L stainless steel flanged collar. The results showed that close to the thermal bridge (copper-steel junction) the stresses slightly exceed the YS of copper at the estimated operating temperature (localised strain-hardening condition). On the other hand, the safety coefficient respect to fracture is well above one for both materials. This condition, together with the fact that limited cooling cycles are expected during the operating life of the system, leads to the assumption that a progressive material hardening will occur in this area, thus locally raising the YS limit.

description: Thermoelectric generation is an essential function of future energy-saving technologies. However, this generation has been an exclusive feature of electric conductors, a situation which inflicts a heavy toll on its application; a conduction electron often becomes a nuisance in thermal design of devices. Here we report electric-voltage generation from heat flowing in an insulator. We reveal that, despite the absence of conduction electrons, a magnetic insulator LaY2Fe5O12 converts a heat flow into spin voltage. Attached Pt films transform this spin voltage into electric voltage by the inverse spin Hall effect. The experimental results require us to introduce thermally activated interface spin exchange between LaY2Fe5O12 and Pt. Our findings extend the range of potential materials for thermoelectric applications and provide a crucial piece of information for understanding the physics of the spin Seebeck effect.

description: The acquisition of deep Near-IR imaging with Wide Field Camera 3 on the Hubble Space Telescope has provided the opportunity to study the very-high redshift Universe. For galaxies up to $z\approx 7.7$ sufficient wavelength coverage exists to probe the rest-frame ultraviolet (UV) continuum without contamination from either Lyman-$α$ emission or the Lyman-$α$ break. In this work we use Near-IR imaging to measure the rest-frame UV continuum colours of galaxies at $4.7
