description: Increased urine albumin excretion is highly prevalent in Hispanics/Latinos. Previous studies have found an association between urine albumin excretion and Amerindian ancestry in Hispanic/Latino populations. Admixture between racial/ ethnic groups creates long-range linkage disequilibrium between variants with different allelic frequencies in the founding populations and it can be used to localize genes. Hispanic/Latino genomes are an admixture of European, African, and Amerindian ancestries. We leveraged this admixture to identify associations between urine albumin excretion (urine albumin-to-creatinine ratio [UACR]) and genomic regions harboring variants with highly differentiated allele frequenciesamongtheancestralpopulations.Admixturemappinganalysis of 12,212HispanicCommunityHealth Study/Study of Latinos participants, using a linearmixedmodel, identified three novel genome-wide significant signals on chromosomes 2, 11, and 16. The admixture mapping signal identified on chromosome2, spanning q11.2-14.1 and notpreviously reported forUACR,isdrivenby a differencebetween Amerindian ancestry and theother twoancestries (P<5.7 × 10-5). Within this locus, two common variants located at the proapoptotic BCL2L11 gene associated with UACR: rs116907128 (allele frequency=0.14;P=1.531027) and rs586283 (Callele frequency=0.35;P=4.2×10-7). In a secondary analysis, rs116907128 accounted for most of the admixture mapping signal observed in the region. The rs116907128 variant is commonamong full-heritage Pima Indians (A allele frequency=0.54) but ismonomorphic in the 1000Genomes European and African populations. In a replication analysis using a sample of full-heritage Pima Indians, rs116907128 significantly associated with UACR (P=0.01; n=1568).Our findingsprovideevidence for thepresenceof Amerindian-specific variants influencing the variation of urine albumin excretion in Hispanics/Latinos.

description: Abstract: Purpose of the Review: Proteins are the central layer of information transfer from genome to phenome and represent the largest class of drug targets. We review recent advances in high-throughput technologies that provide comprehensive, scalable profiling of the plasma proteome with the potential to improve prediction and mechanistic understanding of type 2 diabetes (T2D). Recent Findings: Technological and analytical advancements have enabled identification of novel protein biomarkers and signatures that help to address challenges of existing approaches to predict and screen for T2D. Genetic studies have so far revealed putative causal roles for only few of the proteins that have been linked to T2D, but ongoing large-scale genetic studies of the plasma proteome will help to address this and increase our understanding of aetiological pathways and mechanisms leading to diabetes. Summary: Studies of the human plasma proteome have started to elucidate its potential for T2D prediction and biomarker discovery. Future studies integrating genomic and proteomic data will provide opportunities to prioritise drug targets and identify pathways linking genetic predisposition to T2D development.

Nutrient yields from northwest Atlantic fisheries : analysis, indicators, and optimization
Creators: name: Driscoll, John David
Publisher: name: University of British Columbia
Year: 2020

description: There is a fundamental challenge to the dual objectives of improving ocean health and ending hunger and malnutrition. Seafood derived from fisheries plays a critical role in providing a variety of nutrients to people who are at high risk of malnutrition. However, catches of overfished stocks must be reduced, at least in the near term, to allow stock biomass to rebuild. Reducing catches, in turn, may result in reduced availability of nutrients for people. This suggests that fisheries decisions may have unintended consequences for human nutrition. Currently, nutrition information does not inform fisheries decision-making processes. One challenge to the integration of nutrition and fisheries policy is that fisheries yields are quantified, analyzed, and broadly conceived in terms of the weight of the catch, without regard for the nutrient content of the catch. In this dissertation, I explore this issue from multiple perspectives. In Chapter 2, I analyze the yields of a suite of nutrients obtained from fisheries landings in the Northwest Atlantic Fishery Organization (NAFO) region over the period 1950-2014. Results demonstrate that trends and patterns in nutrient yields can differ, sometimes substantially, from those associated with catch weights. Some species may appear to be minor from a catch weight perspective but play outsized roles in supplying specific nutrients. Notably, recent yields of multiple nutrients have been disproportionately reliant on one species (Atlantic herring, Clupea harengus). In Chapter 3, I evaluate the nutrient yield consequences of the use of Atlantic herring as bait in the Maine fishery for American lobster (Homarus americanus). Results indicate that the lobster fishery likely consumes more nutrients through its use of herring than it produces through lobster landings. In Chapter 4, I present a theoretical approach to optimizing fisheries’ nutrient yields relative to landings weights. This approach maximizes the difference between total nutrient yields and total fishery landings. In Chapter 5, I apply this optimization approach to NAFO fisheries. The results of Chapter 5 indicate that recent NAFO nutrient yields could be maintained at relatively high levels even if total landings were to be reduced.

description: Abstract: The impairment of large-scale brain networks has been observed in dementia with Lewy bodies (DLB) using functional connectivity, but the potential for an analogous effect on structural covariance patterns has not been determined. Twenty-four probable DLB subjects (mean age 74.3 ± 6.7 years, 16.7% female) and 23 similarly aged Controls were included. All participants underwent 3T MRI imaging with high-resolution T1-weighted magnetization-prepared rapid gradient echo (MPRAGE) sequence. Graph theoretical analyses were performed using variation in regional cortical thickness to construct a structural association matrix with pairwise Pearson correlations. Global and nodal graph parameters were computed to assess between-group differences and community structure was studied in order to quantify large-scale brain networks in both groups. In comparison to Controls, DLB subjects had decreased global efficiency, clustering, modularity and small-worldness of structural networks (all p < 0.05). Nodal measures showed that DLB subjects also had decreased clustering in bilateral temporal regions and decreased closeness centrality in extensive areas including right middle frontal, left cingulate and bilateral occipital lobe (all false-discovery rate (FDR)-corrected q < 0.05). Whereas four distinct modules could be clearly identified in Controls, DLB showed extensively disorganized modules, including default-mode network and dorsal attentional network. Our results suggest a marked impairment in large-scale brain structural networks in DLB, mirroring functional connectivity networks disruption.

description: Drain away the earth's oceans and a global pattern of great ridges appears. Adjacent to these continental and undersea mountain ranges are layers of silt and clay, so thick that they fill the gaps between ridges, creating extensive plateaus. Ranging across this planet's higher latitudes are thousands of tiny replicas of these ridge systems. These esker and drumlin swarms run up hills and across streams in roughly parallel discontinuous strands for hundreds of kilometers. Preserved by encapsulation in the ice and snow of our last ice age, eskers, drumlins and their related structures will be the focus of this paper. We contend that Greater and lesser ridge systems alike, including the water and sediments that fill them are cometary debris. Each ridge may be traced to a single stream, or 'jet' of disintegrating materials emanating from shifting areas on a comet's nucleus. A band of these jets, captured into planetary orbit, will land its debris in a unique manner. All debris will be laid down in a sheet perpendicular to the planetary surface, this process which results in the sharp ridge profile, is consistent with the manner in which comets discharge debris along the plane of their orbit. The jet particles, massive enough to resist planetary atmosphere [sands, gravel and boulders] once landed become robust structures through compacting and immediate concretization. The water and lighter materials, diverted by winds and post-depositional melting, flowed and settled into the inter-ridge basins. The establishment of the ridge complexes found on earth is therefore consistent with its initial encounter with a great comet. The ancestral body's return in reduced and fragmented form laid down the lesser esker and drumlin formations.

description: We propose a planar architecture for scalable quantum information processing (QIP) that includes X-junctions through which particles can move without micromotion. This is achieved by adjusting radio frequency (rf) amplitudes to move an rf null along the legs of the junction. We provide a proof-of-principle by transporting dust particles in three dimensions via adjustable rf potentials in a 3D trap. For the proposed planar architecture, we use regularization techniques to obtain amplitude settings that guarantee smooth transport through the X-junction.

description: La tecnologia è in continua evoluzione e la scuola media non può fare altro che adattarsi alla nuova era favorendo l’utilizzo di artefatti tecnologici durante le lezioni. I robot educativi e il loro utilizzo nella didattica sono il punto di partenza per lo svolgimento di questo lavoro di ricerca, in cui si vuole verificare che l’impiego dei robot Thymio incrementi la motivazione e l’interesse dei ragazzi a svolgere attività didattiche. Un altro aspetto che si vuole analizzare è la possibilità di introdurre agli allievi l’argomento della logica a stati che normalmente non viene trattato nella scuola media ma che loro conoscono inconsciamente. I dati per elaborare questa analisi sono stati raccolti in due attività distinte. La prima si è tenuta durante la manifestazione Sportech 2019, mentre la seconda si è svolta in una classe di corso base di quarta media. La ricerca è di tipo quantitativo per l’analisi sulla motivazione degli allievi, mentre è qualitativa per quanto concerne la possibilità di introdurre la logica a stati visto il ridotto campione di allievi. I dati sono stati raccolti attraverso due questionari e con la lettura dei protocolli sviluppati dai ragazzi durante il percorso didattico. I risultati sono molto interessanti e stimolanti. Confermano la possibilità di introdurre gli allievi alla logica a stati e dimostrano quanta influenza abbia la tecnologia sulla didattica, appurando che i ragazzi sono più propensi e motivati a partecipare attivamente alle lezioni.

description: Risk factors for retinal vein occlusion have been extensively studied, with varying population sizes. Smaller populations result in less certain measures of associations. The present review included studies with a relevant population size to identify clinically relevant risk factors for retinal vein occlusion. Understanding the risk factors of retinal vein occlusion is important for the management of these patients. A comprehensive literature review was conducted through a systematic literature search in PubMed and Embase. Additional studies were selected from cross references in the assessed studies. Weighted effect measures were calculated for all included risk factors. Risk factors associated with retinal vein occlusion included cardiovascular diseases, eye diseases, systemic diseases, medical interventions, and sociodemographic factors. This review provided an extensive overview of a wide variety of risk factors increasing the risk of developing retinal vein occlusion. The severity of the identified risk factors indicated that these patients have been in contact with the health care system before their retinal vein occlusion event. Therefore, the clinical course for patients with retinal vein occlusion may benefit from a multidisciplinary collaboration between ophthalmologists and especially cardiologists.

description: We study the game of go from a complex network perspective. We construct a directed network using a suitable definition of tactical moves including local patterns, and study this network for different datasets of professional tournaments and amateur games. The move distribution follows Zipf's law and the network is scale free, with statistical peculiarities different from other real directed networks, such as e. g. the World Wide Web. These specificities reflect in the outcome of ranking algorithms applied to it. The fine study of the eigenvalues and eigenvectors of matrices used by the ranking algorithms singles out certain strategic situations. Our results should pave the way to a better modelization of board games and other types of human strategic scheming.

description: 6′-Sialolactose-modified mono- and bivalent nanobodies were designed and synthesized by a chemoenzymatic strategy. Epidermal growth factor receptor (EGFR)-targeting 7D12 nanobodies, including mono- and bivalent 7D12, were recombinantly expressed in Escherichia coli. Triglycine-modified 6′-sialolactose derivative was synthesized in nine steps. The conjugation of carbohydrates with nanobodies was achieved by Sortase-A mediated ligation with high conversion rates. The obtained glycoengineered nanobodies were finally verified by SDS-PAGE, western blot, and mass spectrometry.

Multi-criteria decision analysis comparing agricultural production methods : protocol for analyzing British Columbia blueberries
Creators: name: El-Sayegh, Rami
Publisher: name: University of British Columbia
Year: 2021

description: INTRODUCTION: Methods such as Multi-criteria decision analysis (MCDA) are often applied to assess how preferences to make rational choices are applied. This thesis aims to examine how farmers balance environmental and social factors of sustainability and health with economic factors (e.g. costs) by assessing their preference for applying alternative agricultural approaches (e.g. conventional, agro-ecological/organic, and integrated farming/mixed-methods). METHODS: First, a systematic bibliometric review of studies that used MCDA techniques for agricultural purposes was conducted to consider the ways that the analytical approach was being applied in this area. The review was restricted to all English language studies of farm-based agricultural studies that considered cost in their analysis. Studies from the Web of Science, CAB Direct, and Agriculture & Environmental Science databases were reviewed to identify publication trends that helped situate the objectives the thesis’ own MCDA feasibility study. Second, a small group (9) of BC Blueberry farmers were interviewed using an Analytic Hierarchy Process (AHP) MCDA technique to elicit their preferred production system while considering potential constraints. The costs of agricultural production systems were divided by the aggregate value scores of the AHP, and systems ranked on their cost-benefit ratio. RESULTS: MCDAs in agriculture have become increasingly popular over time, particularly AHPs in Europe and Asia, and in fruit, vegetable, and nuts farming sectors. Most studies considered costs as one of the criteria in the analysis, most often as a production/operating cost. Health was not mentioned extensively in these studies. The MCDA study showed that organic farming is the most preferred method without the consideration of costs, but conventional farming was the most preferred in the cost-benefit ratio. CONCLUSION: Farmers prefer to be more mixed-methods or ecological (without the consideration of costs), constraints (specifically costs) prevent them from practicing their preferences. As a novel approach in agriculture, the MCDA-CBA is a feasible tool to understand farmer preferences and how they can be advocated for to achieve more sustainable and healthy processes in policy. MCDA-CBA has potential for understanding health and sustainability as connected with similar, if not the same, goals and criteria.

The final results are based on improvement of the methods used earlier, in particular, considerably increased resolution of the charge spectrum. The preliminary conclusions on the significant difference in the spectra of protons and helium nuclei (the proton spectrum is steeper) and the non-power character of the spectra of protons and heavier nuclei (flattening of carbon spectrum at energies above 10 TeV) are confirmed. A complex structure of the energy dependence of the mean logarithm of atomic weight is found.

description: Motivated by the problem of understanding 3-point correlation functions of gauge-invariant operators in N =4 super Yang-Mills theory we consider correlators involving Wilson loops and a "light" operator with fixed quantum numbers. At leading order in the strong coupling expansion such correlators are given by the "light" vertex operator evaluated on a semiclassical string world surface ending on the corresponding loops at the boundary of AdS_5 x S^5. We study in detail the example of a correlator of two concentric circular Wilson loops and a dilaton vertex operator. The resulting expression is given by an integral of combinations of elliptic functions and can be computed analytically in some special limits. We also consider a generalization of the minimal surface ending on two circles to the case of non-zero angular momentum J in S^5 and discuss a special limit when one of the Wilson loops is effectively replaced by a "heavy" operator with charge J.

description: The human sense of smell decreases with age, and a poor sense of smell are among the most important prodromal symptoms of several neurodegenerative diseases. Recent evidence further suggests a racial difference in the sense of smell among U.S. older adults. However, no genome-wide association study (GWAS) on the sense of smell has been conducted in African-Americans (AAs). We performed the first genome-wide meta-analysis of the sense of smell among 1979 AAs and 6582 European-Americans (EAs) from three U.S. aging cohorts. In the AA population, we identified nine novel regions (KLF4-ACTL7B, RAPGEF2-FSTL5, TCF4-LOC100505474, PCDH10, KIAA1751, MYO5B, MIR320B1-CD2, NR5A2-LINC00862, SALL1-C16orf97) that were associated with the sense of smell (P < 5 × 10−8). Many of these regions have been previously linked to neuropsychiatric (schizophrenia or epilepsy) or neurodegenerative (Parkinson’s or Alzheimer’s disease) diseases associated with a decreased sense of smell. In the EA population, we identified two novel loci in or near RASGRP1 and ANXA2P3 associated with sense of smell. In conclusion, this study identified several ancestry-specific loci that are associated with the sense of smell in older adults. While these findings need independent confirmation, they may lead to novel insights into the biology of the sense of smell in older adults and its relationships to neuropsychological and neurodegenerative diseases.

description: We investigate the metric dependence of the partition function of the self-dual p-form gauge field on an arbitrary Riemannian manifold. Using geometric quantization of the space of middle-dimensional forms, we derive a projectively flat connection on its space of polarizations. This connection governs metric dependence of the partition function of the self-dual field. We show that the dependence is essentially given by the Cheeger half-torsion of the underlying manifold. We compute the local gravitational anomaly and show how our derivation relates to the classical computation based on index theory. As an application, we show that the one-loop determinant of the (2,0) multiplet on a Calabi-Yau threefold coincides with the square root of the one-loop determinant of the B-model.

description: We demonstrate single electron shuttling through two coupled nanomechanical pendula. The pendula are realized as nanopillars etched out of the semiconductor substrate. Coulomb blockade is found at room temperature, allowing metrological applications. By controlling the mechanical shuttling frequency we are able to validate the different regimes of electron shuttling.

description: We examine different topological phases in three-dimensional non-centrosymmetric superconductors with time-reversal symmetry by using three different types of topological invariants. Due to the bulk boundary correspondence, a non-zero value of any of these topological numbers indicates the appearance of zero-energy Andreev surface states. We find that some of these boundary modes in nodal superconducting phases are dispersionless, i.e., they form a topologically protected flat band. The region where the zero-energy flat band appears in the surface Brillouin zone is determined by the projection of the nodal lines in the bulk onto the surface. These dispersionless Andreev surface bound states have many observable consequences, in particular, a zero-bias conductance peak in tunneling measurements. We also find that in the gapless phase there appear Majorana surface modes at time-reversal invariant momenta which are protected by a $\mathbb{Z}_2$ topological invariant.

description: Using the SOAR 4.1 m telescope, we report on the discovery of low amplitude pulsations for three stars previously reported as Not-Observed-to-Vary (NOV) by Mukadam et al. (2004) and Mullally et al. (2005), which are inside the ZZ Ceti instability strip. With the two pulsators discovered by Castanheira et al. (2007), we have now found variability in a total of five stars previously reported as NOVs. We also report the variability of eight new pulsating stars, not previously observed, bringing the total number of known ZZ Ceti stars to 148. In addition, we lowered the detection limit for ten NOVs located near the edges of the ZZ Ceti instability strip. Our results are consistent with a pure mass dependent ZZ Ceti instability strip.

Che mestiere fa questo signore? Indagine volta a verificare la conoscenza di una serie di atteggiamenti del fare artistico, che vanno al di là della tradizionale figura del pittore
Creators: name: Blaschitz, Anita
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2013

description: Lo scopo della mia ricerca è stato quello di indagare se gli allievi riescono a riconoscere gli atteggiamenti del fare artistico, che vadano al di là della tradizionale figura del pittore. Per rispondere al mio interrogativo ho intervistato un campione di dodici allievi, appartenenti a ordini di scuola differenti (SI, SE e SM), ai quali ho mostrato delle fotografie di alcuni artisti all’opera e ho chiesto di ipotizzare il mestiere di queste persone. I risultati ottenuti mostrano che la conoscenza degli atteggiamenti del fare artistico alternativi alla pittura è in generale piuttosto contenuta. Gli allievi intervistati, soprattutto i più grandi, hanno utilizzato una terminologia poco ricca per descrivere le pratiche e nessuno è stato in grado di riconoscere gli artisti presentati, figure di spicco nel panorama dell’arte contemporanea, ma soprattutto le loro modalità alternative di fare arte. Durante la formazione scolastica bambini e ragazzi dovrebbero avere la possibilità di sperimentare tecniche differenti alla pittura, ma dai dati raccolti sembrerebbe esserci una discrepanza tra teoria e pratica. Infatti secondo i programmi scolastici gli allievi dovrebbero essere confrontati almeno in parte con atteggiamenti del fare artistico che vadano al di là della pittura (o del disegno), ma in realtà, poiché questi atteggiamenti non sono stati riconosciuti nelle fotografie da me mostrate, sembra non essere così.

Noise and Controllability: suppression of controllability in large quantum systems

description: A closed quantum system is defined as completely controllable if an arbitrary unitary transformation can be executed using the available controls. In practice, control fields are a source of unavoidable noise. Can one design control fields such that the effect of noise is negligible on the time-scale of the transformation? Complete controllability in practice requires that the effect of noise can be suppressed for an arbitrary transformation. The present study considers a paradigm of control, where the Lie-algebraic structure of the control Hamiltonian is fixed, while the size of the system increases, determined by the dimension of the Hilbert space representation of the algebra. We show that for large quantum systems, generic noise in the controls dominates for a typical class of target transformations i.e., complete controllability is destroyed by the noise.

Phylogenetics and evolution of monocot mycoheterotrophs and a newly demonstrated lineage of carnivorous monocots
Creators: name: Lin, Qianshi
Publisher: name: University of British Columbia
Year: 2021

description: I used various approaches to investigate mycoheterotrophic and carnivorous monocots, which obtain essential nutrients from soil fungal partners or animal prey, respectively. Fully mycoheterotrophic plants are unable to photosynthesize, and can be difficult to place in plant phylogeny due to substantial morphological modification and elevated substitution rates in all three plant genomes. Mitochondrial genes are expected to be less susceptible to long-branch artefacts in phylogenetic inference than plastid or nuclear genes, as they generally evolve more slowly. I used a phylogenomic approach considering all 37 protein-coding mitochondrial genes to infer the phylogenetic placements of mycoheterotrophic lineages of monocots. I infer that Thismiaceae (excluding Afrothismia) are distantly related to Burmanniaceae, but that fully mycoheterotrophic Afrothismia (Thismiaceae) is the sister group of photosynthetic Taccaceae and core Thismiaceae. The latter finding supports a further independent loss of photosynthesis in Dioscoreales. Scattered distribution of the cox1 intron in distantly related lineages of monocot mycoheterotrophs supports convergent intron gains, potentially consistent with repeated invasions from soil fungal genomes. I demonstrate that Triantha occidentalis (Tofieldiaceae, Alismatales) is a previously overlooked carnivorous lineage with a sticky-trap inflorescence. Field experiments, isotopic data and mixing models demonstrate significant N transfer from prey, with an estimated 68% of leaf N obtained from capture, comparable to levels for co-occurring sundew. Glandular hairs on flowering stems secrete phosphatase, a digestive enzyme seen in other carnivorous plants. Triantha is nearly unique among carnivorous plants in capturing prey on its inflorescence axis close to flowers; however, its glandular hairs capture only small insects. I also studied Triantha phylogeography across its mostly North American range, by surveying 11 plastid-encoded ndh genes from 75 populations. All three North American species are likely monophyletic, although T. occidentalis monophyly requires recognizing T. japonica as a synonym, which is consistent with its nested position in T. occidentalis, as the sister group of populations in Haida Gwaii (Canada). Plastid ndh genes have experienced various degrees of loss or reading frame interruption within T. glutinosa and T. occidentalis, and a strong geographic signal is evident in patterns of ndh gene loss/pseudogenization across the range of T. occidentalis.
A Faster Routing Scheme for Stationary Wireless Sensor Networks - A Hybrid Approach

description: A wireless sensor network consists of light-weight, low power, small size sensor nodes. Routing in wireless sensor networks is a demanding task. This demand has led to a number of routing protocols which efficiently utilize the limited resources available at the sensor nodes. Most of these protocols are either based on single hop routing or multi hop routing and typically find the minimum energy path without addressing other issues such as time delay in delivering a packet, load balancing, and redundancy of data. Response time is very critical in environment monitoring sensor networks where typically the sensors are stationary and transmit data to a base station or a sink node. In this paper a faster load balancing routing protocol based on location with a hybrid approach is proposed.

description: Shear and bulk viscosities of deconfined gluonic matter are investigated within an effective kinetic theory by describing the strongly interacting medium phenomenologically in terms of quasiparticle excitations with medium-dependent self-energies. We show that the resulting transport coefficients reproduce the parametric dependencies on temperature and coupling obtained in perturbative QCD at large temperatures and small running coupling. The extrapolation into the non-perturbative regime results in a decreasing specific shear viscosity with decreasing temperature, exhibiting a minimum in the vicinity of the deconfinement transition, while the specific bulk viscosity is sizeable in this region falling off rapidly with increasing temperature. The temperature dependence of specific shear and bulk viscosities found within this quasiparticle description of the pure gluon plasma is in agreement with available lattice QCD results.
