description: The LOPES experiment at the Karlsruhe Institute of Technology has been taking radio data in the frequency range from 40 to 80 MHz in coincidence with the KASCADE-Grande air shower detector since 2003. Various experimental configurations have been employed to study aspects such as the energy scaling, geomagnetic dependence, lateral distribution, and polarization of the radio emission from cosmic rays. The high quality per-event air shower information provided by KASCADE-Grande has been the key to many of these studies and has even allowed us to perform detailed per-event comparisons with simulations of the radio emission. In this article, we give an overview of results obtained by LOPES, and present the status and perspectives of the ever-evolving experiment.

description: From its humble beginnings as an immutable ledger of cryptocurrency transactions, blockchain technologyhas evolved into a dynamic platform for the development of trustworthy, decentralized apps. Despite thewidespread usage of blockchain technology, no prior effort has focused on creating an immutable systemfor managing the provenance of scientific data that can automatically verify the records of provenance. Hereat the office, we're using blockchain technology to help with the verification, management, and compilationof data provenance in an honest way. Incidents that enable the CCTV video to be fabricated also becomeapparent as a result of the absence of an effective storage mechanism. Despite the fact that security issuespersist, CCTV video systems have been implemented to tackle this problem. One of the newest technologiesthat can be utilized for data protection is blockchain. The immutable nature of the blockchain provides asolution to the issue of CCTV video counterfeiting.

description: Instantons are tunneling solutions that connect two vacua, and under a small change in the potential, instantons sometimes disappear. We classify these disappearances as smooth (decay rate goes to 0 at disappearance) or abrupt (decay rate not equal to 0 at disappearance). Abrupt disappearances mean that a small change in the parameters can produce a drastic change in the physics, as some states become suddenly unreachable. The simplest abrupt disappearances are associated with annihilation by another Euclidean solution with higher action and one more negative mode; higher-order catastrophes can occur in cases of enhanced symmetry. We study a few simple examples, including the 6D Einstein-Maxwell theory, and give a unified account of instanton disappearances.

description: Understanding model uncertainty is important for many applications. We propose Bootstrap Your Own Variance (BYOV), combining Bootstrap Your Own Latent (BYOL), a negative-free Self-Supervised Learning (SSL) algorithm, with Bayes by Backprop (BBB), a Bayesian method for estimating model posteriors. We find that the learned predictive std of BYOV vs. a supervised BBB model is well captured by a Gaussian distribution, providing preliminary evidence that the learned parameter posterior is useful for label free uncertainty estimation. BYOV improves upon the deterministic BYOL baseline (+2.83% test ECE, +1.03% test Brier) and presents better calibration and reliability when tested with various augmentations (eg: +2.4% test ECE, +1.2% test Brier for Salt & Pepper noise).
Intercropping wheat and barley with nitrogen fixing legume species in low input organic systems
Creators: name: Chapagain, Tejendra
Publisher: name: University of British Columbia
Year: 2014

description: Declining land productivity associated with decreasing soil organic carbon (SOC) and nitrogen (N) is an issue for conventional production of small grains. Intercropping grains with legumes may provide a sustainable solution. I grew wheat (Triticum aestivum cv. ‘Scarlet’) as a monoculture and intercropped with either common bean (Phaseolus vulgaris cv. ‘Red Kidney’, or cv. ‘Black Turtle’), or fava bean (Vicia faba cv. ‘Bell’) in rows of wheat:bean 1:1 and 2:1 as well as broadcast arrangements to assess the effects of genotype and spatial arrangements on crop agronomy, land productivity, biological nitrogen fixation and transfer, N and carbon (C) accumulation in aboveground biomass, soil N balance, gross ecosystem photosynthesis (GEP), net ecosystem productivity (NEP), and water use efficiency (WUE). Barley (Hordeum vulgare cv. ‘Oxbridge’) and pea (Pisum sativum cv. ‘Reward’) were also included based on synchronized maturity, yield potential, protein content, and root architecture. Stable isotope methods (¹³C and ¹⁵N) coupled with field CO₂ exchange measurements were used to determine C and N transformations. Intercrop plots had higher land productivity, improved grain and biomass quality, increased legume nodulation and percent N derived from symbiotic N₂ fixation. Wheat-fava bean in the 1:1 arrangement displayed a 50% increase in land productivity. Barley-pea in the 2:1 arrangement also had the highest total land outputs (5.9 t ha-¹) and land equivalent ratio (1.32). Wheat-fava bean in the 1:1 arrangement fixed the highest amount of N (74 kg N ha-¹), transferred the most N (13% of N in wheat), and accumulated more C (26% higher than wheat monoculture) in shoot biomass. WUE of wheat was improved when grown with fava bean. Pea in intercrop plots also displayed increased nodulation (27-45%) and symbiotic N₂ fixation (9-17%) leading to the addition of 60-78 kg N ha-¹. The GEP and NEP were highest in the 2:1 arrangement and led to the highest daytime C sequestration (229 mg C m-² hr-¹). I demonstrated that intercropping small grains with legumes, in specific spatial arrangements and under low input organic conditions, can counter conventional monoculture-associated SOC and N losses through higher land and ecosystem productivity, and greater organic N-fixation and transfer.

description: E-commerce search and recommendation usually operate on structured data such as product catalogs and taxonomies. However, creating better search and recommendation systems often requires a large variety of unstructured data including customer reviews and articles on the web. Traditionally, the solution has always been converting unstructured data into structured data through information extraction, and conducting search over the structured data. However, this is a costly approach that often has low quality. In this paper, we envision a solution that does entirely the opposite. Instead of converting unstructured data (web pages, customer reviews, etc) to structured data, we instead convert structured data (product inventory, catalogs, taxonomies, etc) into textual data, which can be easily integrated into the text corpus that trains LLMs. Then, search and recommendation can be performed through a Q/A mechanism through an LLM instead of using traditional information retrieval methods over structured data.

description: In this paper we present the results of a survey for radio transients using data obtained from the Very Large Array archive. We have reduced, using a pipeline procedure, 5037 observations of the most common pointings - i.e. the calibrator fields. These fields typically contain a relatively bright point source and are used to calibrate `target' observations: they are therefore rarely imaged themselves. The observations used span a time range ~ 1984 - 2008 and consist of eight different pointings, three different frequencies (8.4, 4.8 and 1.4 GHz) and have a total observing time of 435 hours. We have searched for transient and variable radio sources within these observations using components from the prototype LOFAR transient detection system. In this paper we present the methodology for reducing large volumes of Very Large Array data; and we also present a brief overview of the prototype LOFAR transient detection algorithms. No radio transients were detected in this survey, therefore we place an upper limit on the snapshot rate of GHz frequency transients > 8.0 mJy to rho less than or equal to 0.032 deg^-2 that have typical timescales 4.3 to 45.3 days. We compare and contrast our upper limit with the snapshot rates - derived from either detections or non-detections of transient and variable radio sources - reported in the literature. When compared with the current Log N - Log S distribution formed from previous surveys, we show that our upper limit is consistent with the observed population. Current and future radio transient surveys will hopefully further constrain these statistics, and potentially discover dominant transient source populations. In this paper we also briefly explore the current transient commissioning observations with LOFAR, and the impact they will make on the field.

Marketability of Canadian bitumen : challenges and opportunities
Creators: name: Nevzorov, Maxim
Publisher: name: University of British Columbia
Year: 2014

description: The thesis examines challenges and opportunities for the Canadian oil sands industry in the three most important markets: the USA, currently the sole export destination, and the European Union and China, the two largest potential consumers of highly carbon-intensive Canadian bitumen. Gradually falling demand for oil imports and increasing carbon consciousness in the American market threaten to impose constraints on the further development of Alberta`s oil sands and prompt the industry to look for alternative export destinations. Energy security concerns in the European Union amid the crisis in Ukraine, and in China due to political instability in the Middle East trump environmental policies of the two jurisdictions and present an opportunity for the Canadian bitumen industry to tap into these markets. However, the current infrastructure constraints stemming from formidable public opposition to the construction of new oil pipelines render Canada unable to capitalize on this opportunity. The long-term future of Alberta`s oil sands is therefore far from certain.

description: We study horizontal supergranule-scale motions revealed by TRACE observation of the chromospheric emission, and investigate the coupling between the chromosphere and the underlying photosphere. A highly efficient feature-tracking technique called balltracking has been applied for the first time to the image sequences obtained by TRACE (Transition Region and Coronal Explorer) in the passband of white light and the three ultraviolet passbands centered at 1700 Å, 1600 Å, and 1550 Å. The resulting velocity fields have been spatially smoothed and temporally averaged in order to reveal horizontal supergranule-scale motions that may exist at the emission heights of these passbands. We find indeed a high correlation between the horizontal velocities derived in the white-light and ultraviolet passbands. The horizontal velocities derived from the chromospheric and photospheric emission are comparable in magnitude. The horizontal motions derived in the UV passbands might indicate the existence of a supergranule-scale magnetoconvection in the chromosphere, which may shed new light on the study of mass and energy supply to the corona and solar wind at the height of the chromosphere. However, it is also possible that the apparent motions reflect the chromospheric brightness evolution as produced by acoustic shocks which might be modulated by the photospheric granular motions in their excitation process, or advected partly by the supergranule-scale flow towards the network while propagating upward from the photosphere. To reach a firm conclusion, it is necessary to investigate the role of granular motions in the excitation of shocks through numerical modeling, and future high-cadence chromospheric magnetograms must be scrutinized.

description: Quantification of real-time informal feedback delivered by an experienced surgeon to a trainee during surgery is important for skill improvements in surgical training. Such feedback in the live operating room is inherently multimodal, consisting of verbal conversations (e.g., questions and answers) as well as non-verbal elements (e.g., through visual cues like pointing to anatomic elements). In this work, we leverage a clinically-validated five-category classification of surgical feedback: "Anatomic", "Technical", "Procedural", "Praise" and "Visual Aid". We then develop a multi-label machine learning model to classify these five categories of surgical feedback from inputs of text, audio, and video modalities. The ultimate goal of our work is to help automate the annotation of real-time contextual surgical feedback at scale. Our automated classification of surgical feedback achieves AUCs ranging from 71.5 to 77.6 with the fusion improving performance by 3.1%. We also show that high-quality manual transcriptions of feedback audio from experts improve AUCs to between 76.5 and 96.2, which demonstrates a clear path toward future improvements. Empirically, we find that the Staged training strategy, with first pre-training each modality separately and then training them jointly, is more effective than training different modalities altogether. We also present intuitive findings on the importance of modalities for different feedback categories. This work offers an important first look at the feasibility of automated classification of real-world live surgical feedback based on text, audio, and video modalities.

description: In recent years, a phenomenological solar wind heating model based on a turbulent energy cascade prescribed by the Kolmogorov theory has produced reasonably good agreement with observations on proton temperatures out to distances around 70 AU, provided the effect of turbulence generation due to pickup ions is included in the model. In a recent study [Ng et al., J. Geophys. Res., 115, A02101 (2010)], we have incorporated in the heating model the energy cascade rate based on Iroshnikov-Kraichnan (IK) scaling. We showed that the IK cascade rate can also produce good agreement with observations, with or without the inclusion of pickup ions. This effect was confirmed both by integrating the model using average boundary conditions at 1 AU, and by applying a method [Smith et al., Astrophys. J., 638, 508 (2006)] that uses directly observed values as boundary conditions. The effects due to pickup ions is found to be less important for the IK spectrum, which is shallower than the Kolmogorov spectrum. In this paper, we will present calculations of the pickup ions effect in more details, and discuss the physical reason why a shallower spectrum generates less waves and turbulence.

Implementation of marker-assisted selection in BC forests : perception survey
Creators: name: Nilausen, Chelsea Darshan
Publisher: name: University of British Columbia
Year: 2014

description: The iconic forests of British Columbia are deeply rooted in the lives of its inhabitants. Known for its lush green landscape and old growth trees, BC forests are home to over 1,300 plant and animal species, and provide a playground for recreational activities. The forest industry is also a key contributor to the provincial economy. Over the last decade, the forest sector has experienced a number of challenges as a result of the global economic crisis, the US housing crash, changing markets, low-cost competitors, the strength of the Canadian dollar, and the mountain pine beetle epidemic. Since, the provincial and federal governments have made a commitment to transform the forest sector through innovation, enhanced environmental performance, and new markets. One such area of innovation has been in forest genomic technologies. Marker-assisted selection (MAS) is a biotechnological tool that allows desired traits to be flagged on the genome. This tool may assist tree breeders with the early selection of preferred genotypes, thus reducing the breeding cycle and more accurately and efficiently selecting for improved qualities. However, there is a poor understanding of perceived acceptability towards the adoption of this technology. The objectives of this research were to investigate how the implementation of marker-assisted selection is perceived by forest stakeholders and First Nations in BC, and if this perception is dependent on the context of implementation. To accomplish these objectives, a mixed methods research approach was taken, employing semi-structured individual interviews, followed by a Likert scale questionnaire. Participants were categorized into four groups: government, industry, environmental non-governmental organizations (ENGOs), and First Nations. The results of this analysis found that government and industry participants held positive perceptions towards MAS, supporting its use and continued research in BC. Both agreed that the advantages of MAS outweigh the disadvantages, frequently identifying its benefits in forest regeneration and to tree breeders. ENGOs and First Nations demonstrated a less favourable attitude towards MAS. Their attitudes lie between neutral and negative. Concerns were most strongly focused on environmental impacts, ecosystem degradation, and reduced genetic diversity; while identified benefits were specific to tree breeders and improved tree resiliency.

description: The Strong Lottery Ticket Hypothesis (SLTH) demonstrates the existence of high-performing subnetworks within a randomly initialized model, discoverable through pruning a convolutional neural network (CNN) without any weight training. A recent study, called Untrained GNNs Tickets (UGT), expanded SLTH from CNNs to shallow graph neural networks (GNNs). However, discrepancies persist when comparing baseline models with learned dense weights. Additionally, there remains an unexplored area in applying SLTH to deeper GNNs, which, despite delivering improved accuracy with additional layers, suffer from excessive memory requirements. To address these challenges, this work utilizes Multicoated Supermasks (M-Sup), a scalar pruning mask method, and implements it in GNNs by proposing a strategy for setting its pruning thresholds adaptively. In the context of deep GNNs, this research uncovers the existence of untrained recurrent networks, which exhibit performance on par with their trained feed-forward counterparts. This paper also introduces the Multi-Stage Folding and Unshared Masks methods to expand the search space in terms of both architecture and parameters. Through the evaluation of various datasets, including the Open Graph Benchmark (OGB), this work establishes a triple-win scenario for SLTH-based GNNs: by achieving high sparsity, competitive performance, and high memory efficiency with up to 98.7\% reduction, it demonstrates suitability for energy-efficient graph processing.

Functional analysis of polymorphisms in asthma genes : TSLP and IL1RL1
Creators: name: Akhabir, Loubna
Publisher: name: University of British Columbia
Year: 2014

description: Thymic stromal lymphopoietin (TSLP) and Interleukin 1 receptor-like 1 (IL1RL1) are important for the initiation and maintenance of a Th2 inflammatory environment in the asthmatic lung. TSLP and IL-33, the exclusive IL1RL1 ligand, are secreted by epithelial cells and other immune cells and play essential roles in Th2 polarization, activation and proliferation of immune cells and participate in many asthma cardinal features such as chronic inflammation, airway remodeling and mucus production. TSLP and IL1RL1 are two of the most consistently associated genes in genome-wide association studies of asthma. rs1837253 in TSLP was identified as a putative causal SNP based on consistent association data both from candidate gene and genome-wide association studies; as well as the absence of significant linkage disequilibrium with other single nucleotide polymorphisms (SNPs) in the region. In contrast, there are several asthma-associated IL1RL1 variants and due to the extensive linkage disequilibrium in the region encompassing IL1RL1 and many other genes, potential causal SNP(s) are unknown. In this thesis, I describe the functional analysis of the TSLP SNP rs1837253, the study of SNPs in the IL1RL1 region to identify potentially functional variants by in silico analysis using a lung expression Quantitative Trait Locus dataset and published association data, the functional analysis of the IL1RL1 SNPs: rs1420101 and rs3771180 and finally an analysis of gene expression of TSLP short and long isoforms as well as IL1RL1 receptor and soluble isoforms in relation to clinical phenotypes.

description: In this paper, we formulate two exact charged solutions to the field equations by extending the domain of existing anisotropic models with the help of minimal gravitational decoupling in $f(\mathbb{R},\mathbb{T})$ theory. For this, the anisotropic fluid distribution is considered as a seed source that is extended through the inclusion of a new gravitational source. The influence of the later matter configuration is controlled by the decoupling parameter. We formulate the field equations corresponding to the total matter source that are then decoupled into two distinct sets by implementing a transformation only on the radial metric coefficient. Both of these under-determined sets correspond to their parent sources. Some well-behaved forms of the metric potentials are taken into account to deal with the first set of equations. On the other hand, we solve the second set corresponding to an additional source by taking different constraints on the matter sector. We then consider the radius and mass of a compact star $4U~1820-30$ to analyze the physical feasibility of the resulting solutions for a particular modified model. It is concluded that our resulting solutions show stable behavior for certain values of the decoupling parameter and charge.

description: We perform deep 1.8 cm radio continuum imaging towards thirteen protostellar regions selected from the Spitzer c2d small clouds and cores programme at high resolution (25") in order to detect and quantify the cm-wave emission from deeply embedded young protostars. Within these regions we detect fifteen compact radio sources which we identify as radio protostars including two probable new detections. The sample is in general of low bolometric luminosity and contains several of the newly detected VeLLO sources. We determine the 1.8 cm radio luminosity to bolometric luminosity correlation, L_rad -L_bol, for the sample and discuss the nature of the radio emission in terms of the available sources of ionized gas. We also investigate the L_rad-L_IR correlation and suggest that radio flux density may be used as a proxy for the internal luminosity of low luminosity protostars.

description: Bounded confidence models of opinion dynamics have been actively studied in recent years, in particular, opinion formation and extremism propagation along with other aspects of social dynamics. In this work, after an analysis of limitations of the Deffuant-Weisbuch (DW) bounded confidence, relative agreement model, we propose the Mixed model that takes into account two psychological types of individuals. Concord agents (C-agents) are friendly people; they interact in a way that their opinions get closer always. Agents of the other psychological type show partial antagonism in their interaction (PA-agents). Opinion dynamics in heterogeneous social groups, consisting of agents of the two types, was studied on different social networks. Limit cases of the mixed model, pure C- and PA-societies, were also studied. We found that group opinion formation is, qualitatively, almost independent of the topology of networks used in this work. Opinion fragmentation, polarization and consensus are observed in the mixed model at different proportions of PA- and C-agents, depending on the value of initial opinion tolerance of agents. As for the opinion formation and arising of "dissidents", the opinion dynamics of the C-agents society was found to be similar to that of the DW model, except for the rate of opinion convergence. Nevertheless, mixed societies showed dynamics and bifurcation patterns notably different to those of the DW model. The influence of biased initial conditions over opinion formation in heterogeneous social groups was also studied versus the initial value of opinion uncertainty, varying the proportion of the PA- to C-agents. Bifurcation diagrams showed impressive evolution of collective opinion, in particular, radical change of left to right consensus or vice versa at an opinion uncertainty value equal to 0.7 in the model with the PA/C mixture of population near 50/50.

description: Whether the phenomenology governing MHD turbulence is Kolmogorov or Iroshnikov-Kraichnan (IK) remains an open question, theoretically as well as observationally. The ion heating profile observed in the solar wind provides a quantitative, if indirect, observational constraint on the relevant phenomenology. Recently, a solar wind heating model based on Kolmogorov spectral scaling has produced reasonably good agreement with observations, provided the effect of turbulence generation due to pickup ions is included in the model. Without including the pickup ion contributions, the Kolmogorov scaling predicts a proton temperature profile that decays too rapidly beyond a radial distance of 15 AU. In the present study, we alter the heating model by applying an energy cascade rate based on IK scaling, and show that the model yields higher proton temperatures, within the range of observations, with or without the inclusion of the effect due to pickup ions. Furthermore, the turbulence correlation length based on IK scaling seems to follow the trend of observations better.

description: We investigate the out of equilibrium dynamics of the two-dimensional XY model when cooled across the Berezinskii-Kosterlitz-Thouless (BKT) phase transition using different protocols. We focus on the evolution of the growing correlation length and the density of topological defects (vortices). By using Monte Carlo simulations we first determine the time and temperature dependence of the growing correlation length after an infinitely rapid quench from above the transition temperature to the quasi-long range order region. The functional form is consistent with a logarithmic correction to the diffusive law and it serves to validate dynamic scaling in this problem. This analysis clarifies the different dynamic roles played by bound and free vortices. We then revisit the Kibble-Zurek mechanism in thermal phase transitions in which the disordered state is plagued with topological defects. We provide a theory of quenching rate dependence in systems with the BKT-type transition that goes beyond the equilibrium scaling arguments. Finally, we discuss the implications of our results to a host of physical systems with vortex excitations including planar ferromagnets and liquid crystals as well as the Ginzburg-Landau approach to bidimensional freely decaying turbulence.

Formica integroides of Swakum Mountain : a qualitative and quantitative assessment and narrative of Formica mounding behaviors influencing litter decomposition in a dry, interior Douglas-fir forest in British Columbia
Creators: name: Pati, Adolpho J.
Publisher: name: University of British Columbia

description: Formica spp. mound construction is fundamental to northern forests as their activities govern and shape forest floor dynamics and litter decomposition. The interior Douglas-fir forest at Swakum Mountain contains a super colony of Formica integroides whose presence and monolithic structures dramatically demonstrate their impact on the landscape. Through a series of observations, natural and controlled experiments I examine the effects of Formica mounding on litter decomposition. The basic measurements of temperature, moisture, evolved CO2, and mass loss reveal that Formica mounds buffer litter decomposition as Douglas-fir needles are carefully stacked, stockpiled, and assembled into thatch, where at the depth of ~ 8 cm thatch mass loss minimizes and begins to stabilize. The function of Formica mounding further exacerbates the prevailing arid conditions endemic to this forest type. Cotrufo's Microbial Efficiency-Matrix Stabilization (MEMS) framework sets forth a conceptual model where labile plant constituents are efficiently utilized by microbes and stabilized into soil organic matter (SOM). I integrate my findings within this framework while conceptualizing aspects of complexity theory as potential ecological drivers contributing to soil organic matter formation relating to Formica mounds. Through natural and controlled experiments my overall objective is to describe and explain litter decomposition involving Formica spp. within an interior Douglas-fir forest. I have included descriptive observations, sketches, and photographs involving the forest floor and Formica spp. behaviors and ecology to provide a holistic perspective describing litter decomposition within this local forest type. The framework of scientific methodology combined with a novel approach, provides further empirical and qualitative support for the findings of my research.

description: Guided by a study of kink-antikink scattering in the Gross-Neveu model and other known solutions of the Hartree-Fock approach of a particularly simple type, we demonstrate a quantitative relationship between three different problems: Quantized 1+1-dimensional fermions in the large N limit, solitons of the classical sinh-Gordon equation and classical strings moving in 3-dimensional anti de Sitter space. Aside from throwing light on the relationship between quantum field theory and classical physics, this points to the full solvability of the dynamical N-kink-antikink problem in the Gross-Neveu model.

description: We have studied the distinctive features of the Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) instability and phase transitions in two--dimensional (2D) mesoscopic superconductors placed in magnetic field of arbitrary orientation and rotating superfluid Fermi gases with imbalanced state populations. Using a generalized version of the phenomenological Ginzburg-Landau theory we have shown that the FFLO states are strongly modified by the effect of the trapping potential confining the condensate. The phenomenon of the inhomogeneous state formation is determined by the interplay of three length scales: (i) length scale of the FFLO instability; (ii) 2D system size; (iii) length scale associated with the orbital effect caused either by the Fermi condensate rotation or magnetic field component applied perpendicular to the superconducting disc. We have studied this interplay and resulting quantum oscillation effects in both superconducting and superfluid finite -- size systems with FFLO instability and described the hallmarks of the FFLO phenomenon in a restricted geometry. The finite size of the system is shown to affect strongly the conditions of the observability of switching between the states with different vorticities.
