Characterizing post-fire tree attributes using quantitative structure models based on drone and mobile laser scanning point clouds
Creators: name: Qi, Yangqian
Publisher: name: University of British Columbia
Year: 2022

description: Wildfires burn with a mixture of severities across the landscape and create complex forest structures. Quantifying the structural changes in post-fire forests is critical to evaluating the ecological impacts of wildfires. Advances in drone laser scanning (DLS) and mobile laser scanning (MLS) have enabled the acquisition of high-density point clouds to better resolve detailed tree structures. Yet, few studies have examined their combined capability to describe forest structures. To characterize post-fire tree attributes in interior dry forests in British Columbia, nine study sites in the area burned by the 2017 Elephant Hill wildfire were scanned in 2019 using DLS and MLS. First, I examined the utility of DLS and MLS both individually and combined to estimate tree attributes using quantitative structure models (QSMs) across varying canopy cover levels. Second, I investigated the QSM-derived tree attributes to interpret the effects of burn severities at individual tree and plot scales. The results showed that the fused laser scanning datasets outperformed single laser scanning datasets in estimating tree attributes across canopy cover levels. Specifically, with increasing canopy cover, diameter at breast height, crown diameter, and crown base height were best predicted using the fused data. Height was accurate regardless of canopy cover, which was independent of data collection platforms. Tree volumes could be best modelled by the fused data with increasing canopy cover. In terms of burn severities, the results suggested that smaller pre-fire trees tend to experience higher levels of crown scorch than larger pre-fire trees. Among trees with similar pre-fire sizes, those within mature stands experienced relatively lower levels of crown scorch than those within young stands. At the plot level, low-severity fires had minor effects, moderate-severity fires mostly decreased tree height, and high-severity fires significantly reduced diameter at breast height, height, and biomass. The results also revealed that stands dominated by trees with large crowns and relatively wide spacing could burn less severely than stands characterized by regenerating trees with high densities. The findings of this thesis facilitate forestry practitioners to select appropriate laser scanning tools in forest inventory assessment and develop site-specific management plans for fire-prone forests.

Investigating the effects of land-use land-cover change on carbon and water fluxes from tropical ecosystems using a network of eddy covariance towers
Creators: name: D'Acunha, Brenda Melissa
Publisher: name: University of British Columbia
Year: 2022

description: Tropical ecosystems are key in regulating global carbon (C), water and energy budgets, and are thus central to the global climate system. However, deforestation and land-use and land-cover change (LULCC) continue to rapidly expand in these areas, negatively affecting the ecosystem services they provide. Understanding how C and water fluxes and their main drivers and controlling mechanisms vary depending on biome and land-use change is crucial to predict the effect that further changes in land use and climatic conditions could have on these ecosystems (and by extension, the global climate system). Moreover, this information can be used to develop policies for climate change mitigation and land management. However, our understanding of tropical ecosystems is still limited, mainly because fluxes and their controls can vary greatly due to multiple, interacting factors, and the lack of ground observations. This thesis investigates the effects of LULCC on C and water fluxes using a network of eddy covariance towers located across the state of Mato Grosso, Brazil, including flux towers in natural and managed sites within Amazon forest, Cerrado savanna and Pantanal wetland biomes. Data from the tower network showed that water limitations caused a reduction in carbon and water fluxes during the dry season, particularly in managed sites. Fluxes at natural sites had a strong correlation to a mix of biotic (leaf area index) and environmental drivers (radiation, temperature, soil water content), whereas fluxes were tightly correlated to crop cycles at managed sites. LULCC changed the seasonality of both carbon and water fluxes, which could eventually increase precipitation variability in the region. Increasing the intensity of management (i.e., using irrigation and incorporating cover crops into crop rotations) increased carbon uptake and evapotranspiration, but climate conditions, the choice of cover crop and the time of planting all affected the magnitude of C and water fluxes. The information in this thesis can be used to parameterize and validate climatic models and remote sensing products to improve current and future predictions of carbon and water fluxes, and also to inform management policies in the region.

description: Entangling multiple qubits is one of the central tasks for quantum information processings. Here, we propose an approach to entangle a number of cold ions (individually trapped in a string of microtraps) by a moved cavity. The cavity is pushed to include the ions one by one with an uniform velocity, and thus the information stored in former ions could be transferred to the latter ones by such a moving cavity bus. Since the positions of the trapped ions are precisely located, the strengths and durations of the ion-cavity interactions can be exactly controlled. As a consequence, by properly setting the relevant parameters typical multi-ion entangled states, e.g., $W$ state for 10 ions, could be deterministically generated. The feasibility of the proposal is also discussed.

description: There is an extensive literature on magnetic gradient induced spin relaxation. Cates, Schaefer and Happer (CSH) in a seminal paper, have solved the problem in the regime where diffusion theory (the Torrey equation is applicable using an expansion of the density matrix in diffusion equation eigenfunctions and angular momentum tensors. McGregor has solved the problem in the same regime using a slightly more general formulation using Redfield theory formulated in terms of the auto-correlation function of the fluctuating field seen by the spins and calculating the correlation functions using the diffusion theory Green's function. The results of both calculations were shown to agree for a special case. In the present work we show that the eigenfunction expansion of the Torrey equation yields the expansion of the Green's function for the diffusion equation thus showing the identity of this approach with that of Redfield theory. The general solution can also be obtained directly from the Torrey equation for the density matrix. Thus the physical content of the Redfield and Torrey approaches are identical. We then introduce a more general expression for the position autocorrelation function of particles moving in a closed cell, extending the range of applicability of the theory.

description: The recent long-duration GRB 100316D, associated with supernova SN 2010bh and detected by Swift, is one of the nearest GRB-SNe ever observed (z = 0.059). This provides us with a unique opportunity to study the explosion environment on ~kpc scale in relation to the host galaxy complex. Here we present spatially-resolved spectrophotometry of the host galaxy, focusing on both the explosion site and the brightest star-forming regions. Using these data, we extract the spatial profiles of the relevant emission features (Halpha, Hbeta, [OIII] 5007A, and [NII] 6584A), and use these profiles to examine variations in metallicity and star formation rate as a function of position in the host galaxy. We conclude that GRB 100316D/SN2010bh occurred in a low-metallicity host galaxy, and that the GRB-SN explosion site corresponds to the region with the lowest metallicity and highest star formation rate sampled by our observations.

description: This paper considers three variants of quantum interactive proof systems in which short (meaning logarithmic-length) messages are exchanged between the prover and verifier. The first variant is one in which the verifier sends a short message to the prover, and the prover responds with an ordinary, or polynomial-length, message; the second variant is one in which any number of messages can be exchanged, but where the combined length of all the messages is logarithmic; and the third variant is one in which the verifier sends polynomially many random bits to the prover, who responds with a short quantum message. We prove that in all of these cases the short messages can be eliminated without changing the power of the model, so the first variant has the expressive power of QMA and the second and third variants have the expressive power of BQP. These facts are proved through the use of quantum state tomography, along with the finite quantum de Finetti theorem for the first variant.

title: Problem solving and the barriers to adherence to routine infection control practices
Creators: name: Hamed, Abubaker M.
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: Background: Healthcare-associated infections can be prevented through adherence to Routine Practices (RP) for infection control. Problem solving (PS) is an approach that can potentially be used to promote adherence to RP, which is suboptimal. Objectives: 1) Understand nursing students’ and instructors’ PS related to RP and barriers to RP; 2) evaluate the effects of a Problem-Solving Routine Practices (PSRP) educational program; and 3) examine the issue of negative role models and strategies that can be used. Methods: The objectives were met using a cross-sectional study that surveyed nursing students and instructors, a controlled before and after (CBA) study that evaluated a PSRP educational program, and a discussion paper about role models and adherence to RP. Results: The vast majority (83.5% to 100%) of nursing students and instructors surveyed correctly answered most, but not all, of the questions related to RP and PS. Both groups identified high nursing workload, empty alcohol-based hand rub dispensers and presence of negative role models as the most common barriers, and identified specific strategies to address them. In the CBA, significantly higher proportions of students in the intervention group compared to the control group showed increased confidence about applying PS to deal with high nursing workload (p = 0.032), correctly identified the steps of PS (p = 0.016), and reported adherence to some of the RP components (p < 0.05). The discussion paper highlighted how role models influence adherence and strategies that can be used. Conclusion: Nursing students’ and instructors’ knowledge about some RP components and application of PS to deal with the barriers to RP adherence need to be strengthened. The effectiveness of the PSRP program was varied, but further exploration of this approach is warranted. Recommendations were made for infection control practitioners, educators, nursing administrators, and future research.

description: One model for the origin of typical galactic star clusters such as the Orion Nebula Cluster (ONC) is that they form via the rapid, efficient collapse of a bound gas clump within a larger, gravitationally-unbound giant molecular cloud. However, simulations in support of this scenario have thus far have not included the radiation feedback produced by the stars; radiative simulations have been limited to significantly smaller or lower density regions. Here we use the ORION adaptive mesh refinement code to conduct the first ever radiation-hydrodynamic simulations of the global collapse scenario for the formation of an ONC-like cluster. We show that radiative feedback has a dramatic effect on the evolution: once the first ~10-20% of the gas mass is incorporated into stars, their radiative feedback raises the gas temperature high enough to suppress any further fragmentation. However, gas continues to accrete onto existing stars, and, as a result, the stellar mass distribution becomes increasingly top-heavy, eventually rendering it incompatible with the observed IMF. Systematic variation in the location of the IMF peak as star formation proceeds is incompatible with the observed invariance of the IMF between star clusters, unless some unknown mechanism synchronizes the IMFs in different clusters by ensuring that star formation is always truncated when the IMF peak reaches a particular value. We therefore conclude that the global collapse scenario, at least in its simplest form, is not compatible with the observed stellar IMF. We speculate that processes that slow down star formation, and thus reduce the accretion luminosity, may be able to resolve the problem.

description: The paper deals with a spatially homogeneous and anisotropic universe filled with perfect fluid and dark energy components. The two sources are assumed to interact minimally together with a special law of variation for the average Hubble's parameter in order to solve the Einstein's field equations. The law yields two explicit forms of the scale factor governing the Bianchi-V space-time and constant values of deceleration parameter. The role of dark energy with variable equation of state parameter has been studied in detail in the evolution of Bianchi-V universe. It has been found that dark energy dominates the Universe at the present epoch, which is consistent with the observations. The Universe achieves flatness after the dominance of dark energy. The physical behavior of the Universe has been discussed in detail.

description: We discuss the effect of disorder on the band gap measured in bilayer graphene in optical and transport experiments. By calculating the optical conductivity and density of states using a microscopic model in the presence of disorder, we demonstrate that the gap associated with transport experiments is smaller than that associated with optical experiments. Intrinsic bilayer graphene has an optical conductivity in which the energy of the peaks associated with the interband transition are very robust against disorder and thus provide an estimate of the band gap. In contrast, extraction of the band gap from the optical conductivity of extrinsic bilayer graphene is almost impossible for significant levels of disorder due to the ambiguity of the transition peaks. The density of states contains an upper bound on the gap measured in transport experiments, and disorder has the effect of reducing this gap which explains why these experiments have so far been unable to replicate the large band gaps seen in optical measurements.

title: A STUDY OF THE THERMAL CYCLING PERFORMANCE OF SOLDER JOINTS IN AREA ARRAY PACKAGING
Creators: name: Adeniyi, O
Publisher: name: Liverpool John Moores University
Year: 2021

description: For both the electronics manufacturer and consumer, reliability is an essential characteristic defining the quality of the electronic component and system. Gradual degradation of the electronic components decreases efficiency of the system, and lack of reliability can lead to a significant loss. Efforts at achieving better quality and reliability of electronic components involve the inspection of solder joints in area array packaging. It is of note that solder interconnections are the vulnerable parts of circuit board assemblies (CBA), because they are mainly subjected to various assembly process during electronic manufacturing as well as environmental exposure failures during service. Therefore, the reliability of solder joints is a major concern during the entire life of an area array packaging in order to minimize the electronic failure rate that may lead to large losses. This thesis aims to provide a solution that helps to overcome some of the challenges that can occur during the reliability inspection of solder joints in area array packaging. Firstly, by successfully developing a non-destructive monitoring methodology to study the performance of solder joints under thermal cycling test. The quality of the solder joints in this research work from growth to failure was monitored by using a type of ultrasonic inspection called acoustic micro imaging (AMI). Results indicate that provided a suitable AMI parameters is applied, one can generate a 3D reconstruction of the solder joints images to allow and assess the solder joints’ behaviour in flip chip packages. AMI inspection of solder joints show good agreement with the results obtained that was used to examine how the reliability was affected by the geometry and position of the joints. An automatic segmentation technique was developed that allow to characterize and extract distinctive features of solder joints on different area array packages; such features include mean intensity, structural similarities model and histogram intensity of the region of interest of solder joints. The validation experimental results have been statistically implemented using novel geometrical and time domain features extraction methods like area, form factor and standard deviation. The result from these methods were used to extrapolate the solder joint’s fatigue life at normal operating conditions. Moreover, the analysis of variance (ANOVA) was employed to determine the percentage contribution of solder joints parameters on the acquired images. The results indicated that the thickness of the printed circuit board can affect solder joint reliability.

Development of a measure of hoarding-related risks
Creators: name: Larkin, Persephone
Publisher: name: University of British Columbia
Year: 2022

description: The dysfunction associated with hoarding behaviour sometimes requires intervention from community agencies to reduce risks to occupants and the public. Unfortunately, current measures do not reflect a shared understanding of aspects of the home that are necessary for community service providers to assess in cases of hoarding. Providers differ in their understanding of risks in the home, as they do not consistently use the same measures to conduct assessments, nor are there standard guidelines of what needs to be assessed in hoarded homes. This study aimed to develop a measure that would reflect a collective understanding of essential hoarding-related health and safety risks in the home that require intervention. Study 1 involved a Delphi survey to create a list of items that are critical to assess in hoarded homes. This study identified 32 environmental risk factors to include in the risk assessment measure. Once this part was complete, the Home Environment Assessment Tool for Hoarding (HEATH) was created with these items grouped into five domains. In Study 2, another group of experts assessed the content validity of the resulting measure using the Content Validity Index method. At least 80% of participants endorsed clarity, relevance, and practicality of every item. The index for the overall scale was 0.996, providing strong evidence of content validity. These studies played an essential role in the creation of a risk assessment measure that can improve communication between agencies, track changes from interventions, and standardize risk assessment in hoarded homes.

The algorithm does not require any knowledge of class numbers, and improves the equivalence checking process by using a simple calculation with global units. As an application, we compute ideal classes representatives for an order of level 30 in an algebra over the real quadratic field $\Q[\sqrt{5}]$.

description: Chiral effective field theory (ChEFT) is a modern framework to analyze the properties of few-nucleon systems at low energies. It is based on the most general effective Lagrangian for pions and nucleons consistent with the chiral symmetry of QCD. For energies below the pion-production threshold it is possible to eliminate the pionic degrees of freedom and derive nuclear potentials and nuclear current operators solely in terms of the nucleonic degrees of freedom. This is very important because, despite a lot of experience gained in the past, the consistency between two-nucleon forces, many-nucleon forces and the corresponding current operators has not been achieved yet. In this presentation we consider the recently derived long-range two-pion exchange (TPE) contributions to the nuclear current operator which appear at next-to leading order of the chiral expansion. These operators do not contain any free parameters. We study their role in the deuteron photodisintegration reaction and compare our predictions with experimental data. The bound and scattering states are calculated using five different chiral N2LO nucleon-nucleon (NN) potentials which allows to estimate the theoretical uncertainty at a given order in the chiral expansion. For some observables the results are very close to the reference predictions based on the AV18 NN potential and the current operator (partly) consistent with this force.

description: It is a commonplace to note that in a world governed by special or general relativity, an observer has access only to data within her past lightcone (if that). The significance of this for prediction, and thus for confirmation, does not however seem to have been appreciated. In this paper I show that what we regard as our most well-confirmed relativistic theory, Maxwell's theory of electromagnetism, is not at all well-confirmed in the absence of an additional assumption, the assumption that all fields have sources in their past. I conclude that we have reason to believe that there is a lawlike time-asymmetry in the world.

On the performance of Byzantine fault-tolerant consensus in the blockchain era
Creators: name: Gai, Fangyu
Publisher: name: University of British Columbia

description: Blockchain systems rely on Byzantine fault-tolerant (BFT) consensus protocols to provide replication services that tolerate limited arbitrary behavior among participants. To support large-scale decentralized applications, a scalable and efficient design is the key. This dissertation studies the performance of BFT consensus in the blockchain era including a new BFT paradigm, a nested protocol construction, and a solution to resolve the communication bottleneck of BFT protocols. As blockchain emerges, a new paradigm, combined with decades of research in BFT State Machine Replication (SMR) and blockchain (namely chained-BFT, or cBFT), has been proposed. Chained-BFT protocols have a unifying propose-vote scheme instead of multiple different voting phases with a set of voting and commit rules to guarantee safety and liveness. In this dissertation, we study cBFT protocols following a two-pronged systematic approach. First, we present an evaluation and benchmarking framework, called Bamboo, for quick prototyping of cBFT protocols. Then, to validate our implementations on Bamboo, we introduce an analytic model using queuing theory which also offers a back-of-the-envelope guide for dissecting these protocols. Instead of building a scalable blockchain to replace existing ones, we can use sidechains to scale long-lived blockchains that are troublesome to change. Sidechains enable off-chain scaling by sending transactions in a private network rather than broadcasting them in the public blockchain (i.e., the mainchain) network. In this dissertation, we propose a novel sidechain construction, called Cumulus, which builds BFT-based sidechains atop public blockchains and ensures bidirectional safety of users' assets. Leader-based BFT consensus protocols suffer from the leader bottleneck since most of the communications are drained from the leader node. To alleviate this issue, we attempt to decouple transaction distribution from consensus. Our idea is to have replicas disseminate transactions in a distributed manner and have the leader only propose transaction ids. Stratus uses a provably available broadcast (PAB) protocol to ensure the availability of the referenced transactions. To deal with unbalanced load across replicas, Stratus adopts a distributed load balancing protocol that is co-designed with PAB.

description: This Article analyses to what extent the EU values and principles are guiding the external dimension of EU migration policies, especially the principle of democracy and fundamental rights. To illustrate this, it elaborates on the consequences of the informalization of this cooperation, and of the lack of safeguards for fundamental rights compliance. In the second part, the Article analyses the consequences of the increasing tendency to apply conditionality in the external migration cooperation, illustrated with three recent examples (Union Visa Code, post-Cotonou Agreement and trade tariff preferences). While referencing to political science research from the perspective of third countries, the Article concludes that the conditionality approach also risks undermining the principles of equality and sincere cooperation, which eventually impede the effectiveness of the external dimension on migration policies. By drawing lessons from the internal rule of law mechanisms, the EU could bring the external cooperation on migration more in line with its own values and principles enshrined in the Treaties. By doing so, it would offer the necessary safeguards for more coherence in the EU’s policies.

description: In this paper we consider sparse and identifiable linear latent variable (factor) and linear Bayesian network models for parsimonious analysis of multivariate data. We propose a computationally efficient method for joint parameter and model inference, and model comparison. It consists of a fully Bayesian hierarchy for sparse models using slab and spike priors (two-component delta-function and continuous mixtures), non-Gaussian latent factors and a stochastic search over the ordering of the variables. The framework, which we call SLIM (Sparse Linear Identifiable Multivariate modeling), is validated and bench-marked on artificial and real biological data sets. SLIM is closest in spirit to LiNGAM (Shimizu et al., 2006), but differs substantially in inference, Bayesian network structure learning and model comparison. Experimentally, SLIM performs equally well or better than LiNGAM with comparable computational complexity. We attribute this mainly to the stochastic search strategy used, and to parsimony (sparsity and identifiability), which is an explicit part of the model. We propose two extensions to the basic i.i.d. linear framework: non-linear dependence on observed variables, called SNIM (Sparse Non-linear Identifiable Multivariate modeling) and allowing for correlations between latent variables, called CSLIM (Correlated SLIM), for the temporal and/or spatial data.

description: We demonstrate cavity sideband cooling of a single collective motional mode of an atomic ensemble down to a mean phonon occupation number of 2.0(-0.3/+0.9). Both this minimum occupation number and the observed cooling rate are in good agreement with an optomechanical model. The cooling rate constant is proportional to the total photon scattering rate by the ensemble, demonstrating the cooperative character of the light-emission-induced cooling process. We deduce fundamental limits to cavity-cooling either the collective mode or, sympathetically, the single-atom degrees of freedom.

Entropic formulation of the uncertainty principle for the number and annihilation operators

description: An entropic approach to formulating uncertainty relations for the number-annihilation pair is considered. We construct some normal operator that traces the annihilation operator as well as commuting quadratures with a complete system of common eigenfunctions. Expanding the measured wave function with respect to them, one obtains a relevant probability distribution. Another distribution is naturally generated by measuring the number operator. Due to the Riesz-Thorin theorem, there exists a nontrivial inequality between corresponding functionals of the above distributions. We find the bound in this inequality and further derive uncertainty relations in terms of both the Renyi and Tsallis entropies. Entropic uncertainty relations for continuous distribution as well as relations for discretized one are presented.

title: Performing Exile, Music and Politics: El Sueño Existe Festival in Wales and the Legacy of Víctor Jara
Creators: name: Rivera Volosky, Ignacio
Publisher: name: Goldsmiths, University of London
Year: 2019

description: This thesis examines how diasporic, musical and political identities are performed, contested and reaffirmed in El Sueño Existe, a festival of Latin American music and politics that takes place every two years in Machynlleth, Wales. Set up in 2005, this festival commemorates the legacy of Chilean artist Víctor Jara and the movement ‘New Chilean Song’ of which he was a part. Victor Jara was a musician and theatre director who was killed a few days after the Chilean Military Coup in September 1973, and who since his death has become a symbol of international solidarity and the defence of human rights (McSherry 2015b). The methodology is based on a performance epistemology (Taylor 2003) and included my own participation in the festival as a member of the public, a member of the organisation, and a musician. In addition, I have conducted interviews with several festival-goers, focusing on their biographies, experiences and opinions of Victor Jara, New Chilean Song and the festival.

Based on discussions of cultural performance (Turner 1987; Taylor 2007), the sociology of music (Frith 1996b; DeNora 2000) and theory of performativity (Bell 1999; Fortier 1999), I suggest that the festival is a space that simultaneously acts to both suspend and to create normativity. I argue that El Sueño Existe festival is a liminal space for Chilean exiles, international musicians and political activists which ultimately works to reaffirm political, musical and diasporic identities, through the re-enactment of a set of repertoires that promote a sense of belonging and identification. The process of reaffirmation is not exclusively created by the means of breaking normativity in a symbolic domain; it is also constructed through the reproduction of hierarchies and discourses that create membership among the people who belong to the community.

Collider Bounds on Lee-Wick Higgs Bosons

description: We study the constraints on the Lee-Wick Higgs sector arising from direct collider searches. We work in an effective-field theory framework, where all of the Lee-Wick partners are integrated out, with the sole exception of the Lee-Wick Higgs bosons. The resulting theory is a two-Higgs doublet model where the second doublet has wrong-sign kinetic and mass terms. We include the bounds coming from direct Higgs searches at both LEP and Tevatron using the code HiggsBounds, and show the currently excluded parameter space. We also analyze the prospects of LHC Run-I, finding that with a total integrated luminosity of 5 fb $^{-1}$ and a center-of-mass energy of 7 TeV, most of the parameter space for the SM-like CP-even Higgs will be probed.
