description: Given a directed graph $G$ with non negative cost on the arcs, a directed tree cover of $G$ is a rooted directed tree such that either head or tail (or both of them) of every arc in $G$ is touched by $T$. The minimum directed tree cover problem (DTCP) is to find a directed tree cover of minimum cost. The problem is known to be $NP$-hard. In this paper, we show that the weighted Set Cover Problem (SCP) is a special case of DTCP. Hence, one can expect at best to approximate DTCP with the same ratio as for SCP. We show that this expectation can be satisfied in some way by designing a purely combinatorial approximation algorithm for the DTCP and proving that the approximation ratio of the algorithm is $\max\{2, \ln(D^+)\}$ with $D^+$ is the maximum outgoing degree of the nodes in $G$.

description: We have observed interference between two Bose-Einstein condensates of weakly bound Feshbach molecules of fermionic $^6$Li atoms. Two condensates are prepared in a double-well trap and, after release from this trap, overlap in expansion. We detect a clear interference pattern that unambiguously demonstrates the de Broglie wavelength of molecules. We verify that only the condensate fraction shows interference. For increasing interaction strength, the pattern vanishes because elastic collisions during overlap remove particles from the condensate wave function. For strong interaction the condensates do not penetrate each other as they collide hydrodynamically.
Shear modulus in viscoelastic solid $^4$He

description: The complex shear modulus of solid $^4$He exhibits an anomaly in the same temperature region where torsion oscillators show a change in period. We propose that the observed stiffening of the shear modulus with decreasing temperature can be well described by a viscoelastic component that possesses an increasing relaxation time as temperature decreases. Since a glass is a viscoelastic material, the response functions derived for a viscoelastic material are identical to those obtained for a glassy component due to a time delayed restoring back-action. By generalizing the viscoelastic equations for stress and strain to a multiphase system of constituents, composed of patches with different damping and relaxation properties, we predict that the maximum change of the magnitude of the shear modulus and the maximum height of the dissipation peak are independent of an applied external frequency. The same response expressions allow us to calculate the temperature dependence of the shear modulus' amplitude and dissipation. Finally, we demonstrate that a Vogel-Fulcher-Tammann (VFT) relaxation time is in agreement with available experimental data.

Olivine diversity in the Leslie kimberlite, NT, Canada : implications for transport and emplacement processes
Creators: name: Landoni, Katherine
Publisher: name: University of British Columbia
Year: 2022

description: Olivine crystals are ubiquitous in kimberlites and record petrologic events through all stages of ascent and eruption. Well-preserved olivine from the Leslie kimberlite, NT, Canada elucidates the sequence of events attending kimberlite emplacement. The Leslie kimberlite mainly hosts a single phase of extrusive coherent kimberlite. We used spatially distributed samples (n = 76) from drill core to develop a 3D representation of the Leslie kimberlite. Petrographic investigation defined four distinct olivine populations: phenocrysts, macrocrysts, dunite “nodules”, and mantle xenolith-hosted olivine. SEM imagery, and major and trace element geochemistry were used to characterize and quantify chemical zonation including xenocrystic cores, mid-zones, magmatically crystallized rims, high-Mg rinds, and/or monticellite coronas. Core compositions (Fo85.7 to Fo93.8, NiO ~0.36 wt%) and other textural evidence show that cores are mantle-derived olivine xenocrysts. Mid-zones developed on cores show a sharp decrease in Fo content (~Fo90.9) across irregular, convoluted, and embayed contacts indicating disequilibrium and partial dissolution of the olivine xenocrysts combined with diffusion-driven replacement. Magmatically crystallized olivine rims can jacket xenocrystic cores and mid-zones. Rims have uniform and distinctive chemical compositions of ~Fo91.8 ± 0.7 (2σ) and NiO concentrations that decrease (~0.4 wt% to ~0.1 wt%) outward. Rinds, thin outer fringes, have a convoluted inner contact and a sawtooth contact with the groundmass. Rind compositions have high ~Fo97.1, low NiO, and elevated Mn and Ca. Rind textural relationships and compositions suggest a non-magmatic, post-emplacement origin. The four olivine populations and chemical zonation (only cores, mid-zones, and rims) are uniformly and consistently distributed throughout the Leslie kimberlite. Thus, olivine within a single phase of kimberlite predominantly records pre-emplacement processes and illustrates that magma batches become well mixed during ascent and emplacement. In contrast, both late-stage high-Mg rinds and monticellite coronas are non-uniformly distributed throughout the pipe. Utilizing olivine geochemistry, coupled with petrographic observations, we reconstruct a sequence of events of the Leslie kimberlite ascent and eruption. Our results indicate olivine entrainment and ascent (within a single kimberlite phase) may be sufficiently characterized by a few samples. Conversely, syn- and post-emplacement processes recorded by olivine require systematic sampling to capture all potential heterogeneities within a given kimberlite phase.

description: We study the behaviour of the flux tube thickness in the vicinity of the deconfinement transition. We show, using effective string methods, that in this regime the square width increases linearly and not logarithmically with the interquark distance. The amplitude of this linear growth is an increasing function of the temperature and diverges as the deconfinement transition is approached from below. These predictions are in good agreement with a set of simulations performed in the 3d gauge Ising model.

description: Inhomogeneous electronic states resulting from entangled spin, charge, and lattice degrees of freedom are hallmarks of strongly correlated electron materials; such behavior has been observed in many classes of d-electron materials, including the high-Tc copper-oxide superconductors, manganites, and most recently the iron-pnictide superconductors. The complexity generated by competing phases in these materials constitutes a considerable theoretical challenge-one that still defies a complete description. Here, we report a new manifestation of electronic inhomogeneity in a strongly correlated f-electron system, using CeCoIn5 as an example. A thermodynamic analysis of its superconductivity, combined with nuclear quadrupole resonance measurements, shows that nonmagnetic impurities (Y, La, Yb, Th, Hg and Sn) locally suppress unconventional superconductivity, generating an inhomogeneous electronic "Swiss cheese" due to disrupted periodicity of the Kondo lattice. Our analysis may be generalized to include related systems, suggesting that electronic inhomogeneity should be considered broadly in Kondo lattice materials.

title: Using measures of corticospinal excitability to map symptom severity in multiple sclerosis
Creators: name: Wiseman, Hailey
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Background: Transcranial magnetic stimulation (TMS) is a tool used to measure corticospinal excitability. To evaluate the usefulness of TMS as a biomarker in multiple sclerosis (MS), the first step is to examine how well variables derived using TMS align with clinical symptoms of MS.
 Methods: Participants with MS (n=38) were assigned to motor, cognitive, sensory, or asymptomatic clinical group based on their Expanded Disability Status Scale (EDSS) assessment. Following recording of demographic information, subjective health and scoring of walking and cognition, TMS measures were collected from each brain hemisphere. We first examined whether TMS parameters (resting motor threshold (RMT), active motor threshold (AMT), and cortical silent period (CSP)) would differ among clinical groups. Next, we examined whether TMS parameters predicted severity of symptoms.
 Results: CSP and AMT in the hemisphere corresponding to the weaker hand predicted measures of symptom severity among people with MS in the motor and cognitive profile groups. Longer CSP was the strongest predictor of slower walking speed (F(1,17)=22.82, p<0.001). Higher AMT was the strongest predictor of cognitive impairment using the Montreal Cognitive Assessment (F(1,17)==25.29, p=0.001) and perceived physical impact of MS using the Multiple Sclerosis Impact Scale-29 (F(1,17)=30.63, p<0.001).
 Conclusions: CSP and AMT in the hemisphere corresponding to the weaker hand predicted severity of symptoms among people with MS in the motor and cognitive groups. In these cases, TMS variables provided greater predictive value than the traditional EDSS, supporting the use of TMS outcomes as biomarkers in MS.

Tidal influence on the Fraser River plume
Creators: name: Li, Shumin
Publisher: name: University of British Columbia
Year: 2022

description: The Fraser River plume in the Strait of Georgia, BC, is significantly influenced by the tide. Here we use 17 years of daily MODIS observations of suspended particulate matter to understand the tidal variability of the plume. Our results show a consistent negative correlation between the Fraser River plume area and the tidal elevation with a phase lag at about one hour from two independent methods. The plume area routinely increases/decreases by about 20% during the ebb/flood tides, and a lower river flowrate typically leads to a more dramatic tidal variation in the plume area. A tidal harmonic analysis is performed on the HF-radar derived surface currents, and the difference between the extents of diurnally and semi-diurnally driven river influence suggests two distinct dynamical regions in the horizontal plume structure. A simple analytical model based on the volume conservation and salinity balance equations is built to analyze the mechanism of the tidal variability in the plume size. The observed tidal patterns of the plume area variation are partly reproduced using tidally modulated plume salinity (observed from instrumented ferries) and river flowrate (from numerical model outputs). These new findings will improve our understanding of the short-term dynamics of the Fraser River plume.
The radio/gamma-ray connection in Fermi-blazars

description: We study the correlation between the gamma-ray flux F_g, averaged over the first 11 months of Fermi survey and integrated above 100 MeV, and the radio flux density (F_r at 20 GHz) of Fermi sources associated with a radio counterpart in the AT20G survey. Considering the blazars detected in both bands, the correlation is highly significant and it is F_g~F_r^0.85+-0.04, similar for BL Lac and FSRQ sources. However, only a small fraction (~1/15) of the AT20G radio sources with flat radio spectrum, are detected by Fermi. To understand if this correlation is real, we examine the selection effects introduced by the flux limits of the radio and gamma-ray surveys, and the importance of variability of the gamma-ray flux. We find that the radio/gamma-ray flux correlation is real, but its slope is steeper than the observed one, i.e. F_g~F_r^delta with delta in the range 1.25-1.5. The observed F_g-F_r correlation and the fraction of radio sources detected by Fermi is reproduced assuming a long term gamma-ray flux variability following a log-normal probability distribution with standard deviation sigma>0.5 (corresponding to F_g varying by at least a factor 3). Such a variability is compatible with what observed when comparing, for the sources in common, the EGRET and the Fermi gamma-ray fluxes (even if the Fermi fluxes are averaged over ~1 year). Another indication of variability is the non detection of 12 out of 66 EGRET blazars by Fermi, despite its higher sensitivity.We also study the strong linear correlation between the gamma-ray and the radio luminosity of the 144 AT20G-Fermi associations with known redshift and show that it is statistically robust. Two possible implications of these correlations are discussed: the contribution of blazars to the extragalactic gamma-ray background and the prediction of blazars that might undergo extremely high states of gamma-ray emission in the next years.

description: High levels of bacterial antimicrobial resistance (AMR) have been reported in many environmental studies conducted in Ireland and elsewhere. The inappropriate use of antibiotics in both human and animal healthcare as well as concentrations of residual antibiotics being released into the environment from wastewaters are thought to be contributing factors. Few reports of AMR in drinking water-associated microbes are available for Ireland or internationally. We analysed 201 enterobacterales from group water schemes and public and private water supplies, only the latter having been surveyed in Ireland previously. The organisms were identified using conventional or molecular techniques. Antimicrobial susceptibility testing for a range of antibiotics was performed using the ARIS 2X interpreted in accordance with EUCAST guidelines. A total of 53 Escherichia coli isolates, 37 Serratia species, 32 Enterobacter species and enterobacterales from seven other genera were identified. A total of 55% of isolates were amoxicillin resistant, and 22% were amoxicillin-clavulanic acid resistant. A lower level of resistance (<10%) was observed to aztreonam, chloramphenicol, ciprofloxacin, gentamicin, ceftriaxone and trimethoprim-sulfamethoxazole. No resistance to amikacin, piperacillin/tazobactam, ertapenem or meropenem was detected. The level of AMR detected in thisstudy was low but not insignificant and justifies ongoing surveillance of drinking water as a potential source of antimicrobial resistance.

QUANTIFYING THE EFFECTS OF CLIMATE ON RANGELAND VEGETATION PRODUCTIVITY AND ECONOMIC CONSEQUENCES AT A RANCH LEVEL
Creators: name: Wold, Aaron
Publisher: name: Washington State University

Subjects: Remote Sensing

description: Ranches in the western US rely on rangeland forage production for low-cost feed to produce beef cattle. The threat of a changing climate and increased drought will increase the variability of forage production. To our knowledge, there is little research that couples observational data from satellite remote sensing to economic outcomes for individual livestock producers. In this study, we utilized Landsat-based plant productivity estimates to create a monthly forage production dataset from 1986 to 2018 on a hypothetical 300-head, 21,000-acre ranch in central Idaho. To capture the relationship between annual forage production and climate, we evaluated the forage estimates against climate variables using multivariable linear regression models. Forage estimates were then used to create scenarios for use in an economic model that was parameterized for a representative 300-head cattle ranch to assess economic outcomes (i.e., net income, cost per cow, and optimal herd size). I developed two sets of scenarios which I refer to as (1) the Climate Trends scenario and (2) the Drought Episodes scenario. The Climate Trends scenario evaluated the consequences of two 40-year mean decreases in forage production. The Drought Episode scenarios evaluated the effects of a 10-year moderate and 5-year severe drought during a 40-year time horizon. I found that the forage estimates have a strong relationship with climate, revealing that annual precipitation, mean annual temperature and mean vapor pressure deficit can explain close to 60 percent of the variability in annual forage production. Furthermore, I found that a ranch’s income is sensitive to rangeland forage production and that drought (i.e., low precipitation, high temperatures, and high vapor pressure deficits) can lead to reduced economic viability such as a 20% decrease in net income and a 10% decrease in optimal herd size during a severe drought. A better understanding of the impacts of climate variability on ranch income will lead to improved management decisions and increased ranch resiliency to future drought episodes.

Creators: name: Smith, Jordan
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: This thesis provides a proof-of-concept approach to the analysis of ultrasound imagery using machine learning and computer vision for the purposes of tracking relative changes in apparent circulating blood volume.
 Data for the models was collected from a simulation which involved having healthy subjects recline at angles between 0 and 90 degrees to induce changes in the size of the internal jugular vein (IJV) resulting from gravity. Ultrasound video clips were then captured of the IJV. The clips were segmented, followed by feature generation, feature selection and training of predictive models to determine the angle of inclination. This research provides insight into the feasibility of using automated analysis techniques to enhance portable ultrasound as a monitoring tool.
 In a dataset of 34 subjects the angle was predicted within 11 degrees. An accuracy of 89% was achieved for high/low classification.
New Strategy for B_s Branching Ratio Measurements and the Search for New Physics in B^0_s -> mu^+ mu^-

description: The LHCb experiment at CERN's Large Hadron Collider will soon allow us to enter a new era in the exploration of B_s decays. A particularly promising channel for the search of "new physics" is B^0_s -> mu^+ mu^-. The systematic key uncertainty affecting the measurement of this -- and in fact all B_s-decay branching ratios -- is the ratio of fragmentation functions f_d/f_s. As the presently available methods for determining f_d/f_s are not sufficient to meet the high precision at LHCb, we propose a new strategy using \bar B^0_s -> D_s^+ pi^- and \bar B^0_d -> D^+ K^-. It allows us to obtain a lower experimental bound on BR(B^0_s -> mu^+ mu^-) which offers a powerful probe for new physics. In order to go beyond this bound and to determine f_d/f_s with a theoretical precision matching the experimental one it is sufficient to know the SU(3)-breaking correction to a form-factor ratio from non-perturbative methods at the level of 20%. Thanks to our strategy, we can detect new physics in B^0_s -> mu^+ mu^- at LHCb with 5 sigma for a branching ratio as small as twice the Standard-Model value, which represents an improvement of the new-physics reach by about a factor of two with respect to the current LHCb expectation.

title: Effects of clear-cut created ecotones on nocturnal macromoths in western Newfoundland, Canada
Creators: name: Pinksen, Jasmine
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Human land use practices, especially clearing of native vegetation, tend to increase edges, creating ecotones. Ecotones are important transition zones for conservation, as they are species rich and promote biological diversity, thus they have become a focus of habitat management. Arthropod groups are known to be significantly more abundant and/or taxonomically diverse at the edges compared to the interior of the adjacent habitats There is, however, a knowledge gap with respect to lepidopteran diversity across anthropogenic ecotones in boreal forests.
 To address one of these knowledge gaps, I asked how forestry-created ecotones influence nocturnal macromoth assemblages in the eastern boreal forest. I sampled moths in western Newfoundland, Canada, to determine their responses at the local spatial scale. Sampling took place in four replicate sites, each with light traps placed in a clear-cut, adjacent forest, and the edge between them. Edges supported the highest abundance of nocturnal macromoths, forests supported an intermediate amount, and clear-cuts supported the lowest. The difference between the habitat that supported the highest abundance and the habitat that supported the lowest, i.e.edges and clear-cuts, was significant.While boasting many unique species, edges represented a macro-moth assemblage composition that was intermediate between clear-cuts and forests, and all habitats differed significantly. While composition differed significantly between the three habitats, there was no significant difference in species diversity among the three habitat types. The results of my study suggest that, like natural disturbance created edges, forest-clear-cut edges may serve as unique habitats for macro-moth assemblages in the boreal forest. These results also have important implications for the maintenance of biodiversity in the boreal and forestry in the context of natural disturbance emulation.
An MRI-Derived Definition of MCI-to-AD Conversion for Long-Term, Automati c Prognosis of MCI Patients

description: Alzheimer's disease (AD) and mild cognitive impairment (MCI), continue to be widely studied. While there is no consensus on whether MCIs actually "convert" to AD, the more important question is not whether MCIs convert, but what is the best such definition. We focus on automatic prognostication, nominally using only a baseline image brain scan, of whether an MCI individual will convert to AD within a multi-year period following the initial clinical visit. This is in fact not a traditional supervised learning problem since, in ADNI, there are no definitive labeled examples of MCI conversion. Prior works have defined MCI subclasses based on whether or not clinical/cognitive scores such as CDR significantly change from baseline. There are concerns with these definitions, however, since e.g. most MCIs (and ADs) do not change from a baseline CDR=0.5, even while physiological changes may be occurring. These works ignore rich phenotypical information in an MCI patient's brain scan and labeled AD and Control examples, in defining conversion. We propose an innovative conversion definition, wherein an MCI patient is declared to be a converter if any of the patient's brain scans (at follow-up visits) are classified "AD" by an (accurately-designed) Control-AD classifier. This novel definition bootstraps the design of a second classifier, specifically trained to predict whether or not MCIs will convert. This second classifier thus predicts whether an AD-Control classifier will predict that a patient has AD. Our results demonstrate this new definition leads not only to much higher prognostic accuracy than by-CDR conversion, but also to subpopulations much more consistent with known AD brain region biomarkers. We also identify key prognostic region biomarkers, essential for accurately discriminating the converter and nonconverter groups.
Linear information theory and its application to the coded caching problem

description: We investigate the peculiar properties of information theory when all random variables involved are linear functions of a given source endowed with the structure of a Z/2Z-vector space. We describe the coded caching problem and review the progress made in particular cases of the problem. We devise a new caching scheme for a special instance of the problem and extend some approaches in the coded caching literature to the linear case such that we can use our results in linear algebra to drive new lower bounds. We show one example within coded caching, with the linearity assumption, where our results in information theory lead to stronger bounds. Our results infer certain "qualitative" aspects of caching schemes, using the information they must contain, rather than giving a complete analysis of such schemes.

description: We critically discuss the stability of edge states and edge magnetism in zigzag edge graphene nanoribbons (ZGNRs). We point out that magnetic edge states might not exist in real systems, and show that there are at least three very natural mechanisms - edge reconstruction, edge passivation, and edge closure - which dramatically reduce the effect of edge states in ZGNRs or even totally eliminate them. Even if systems with magnetic edge states could be made, the intrinsic magnetism would not be stable at room temperature. Charge doping and the presence of edge defects further destabilize the intrinsic magnetism of such systems.

description: Concrete is a construction product that has been used for thousands of years. The compressive strength properties as well as its workability and low cost make concrete a leading material in structural applications. Typical quality tests for concrete include compression tests, where the concrete is allowed to cure for 7, 14, or 28 days. It is desirable to quickly and accurately assess the quality of the uncured no slump concrete moments after manufacturing. The benefits include reassuring customers about the concrete quality while saving time, money, resources and identifying inadequate product early in the production stages. Currently, an operator stands by the machine to check quality by visually inspecting and poking the concrete blocks. The same tactile and visual approach is repeated for all product and after machine adjustments. The approach is highly subjective as the decisions vary due to several factors. In this research, we aim to develop a robotic quality inspection station using a cobot equipped with a force sensing finger to automate the inspection process. The research involved several setups to collect data for a machine learning (ML) model utilizing the K-nearest neighbor (KNN) algorithm. The model has been incorporated into the cobot control so that the cobot can evaluate blocks in real time against the ML model to determine good or bad block quality. Design of the inspection systemalong with the experiments conducted with quartz flour and concrete blocks are explained. Details of the ML model and the integration into the cobot operation are discussed. Results from automatic quality assessment experiments with the cobot are compared to operator predictions of quartz flour and concrete blocks. Recommendations are made to continue with the development of the inspection system.

description: We analyze the reliability of oxygen abundances and ionization parameters obtained from different diagnostic diagrams. For this, we compiled from the literature observational emission line intensities and oxygen abundance of 446 star-forming regions whose O/H abundance was determined by direct estimation of electron temperature. The abundances compiled were compared with the values calculated in this work using different diagnostic diagrams in combination with results from a grid of photoionization models. We found that the [\ion{O}{iii}]/[\ion{O}{ii}] vs. [\ion{N}{ii}]/[\ion{O}{ii}], [\ion{O}{iii}]/H$β$ vs. [\ion{N}{ii}]/[\ion{O}{ii}], and ([\ion{O}{iii}]/H$β$)/([\ion{N}{ii}]/H$α$) vs. [\ion{S}{ii}]/[\ion{S}{iii}] diagnostic diagrams give O/H values close to the $T_{\rm e}$-method, with differences of about 0.04 dex and dispersion of about 0.3 dex. Similar results were obtained by detailed models but with a dispersion of 0.08 dex. The origin of the dispersion found in the use of diagnostic diagrams is probably due to differences between the real N/O-O/H relation of the sample and the one assumed in the models. This is confirmed by the use of detailed models that do not have a fixed N/O-O/H relation. We found no correlation between ionization parameter and the metallicity for the objects of our sample. We conclude that the combination of two line ratio predicted by photoionization models, one sensitive to the metallicity and another sensitive to the ionization parameter, which takes into account the physical conditions of star-forming regions, gives O/H estimates close to the values derived using direct detections of electron temperatures.
