description: Laws protecting intellectual property rights encourage private sector seed research and development. This report examines the Plant-Variety Protection Act (the PVPA) of 1970 as well as the Plant Patent Act (PPA) of 1930 and other forms of research protection, such as utility patents (UP's) and trade secrecy. The report explores the relative profitability to farmers of using purchased seed rather than bin run seed (the previous year's harvest), since the use of purchased seed encourages private seed research and development. To compare profits, winter wheat yields are regressed against the source of seed and other variable inputs for three sections of the United States in 1986/87 and 1987/88. The results show that, on average, farmers who use bin run seed could increase yields by using purchased seed. Also, profits would probably increase both for farmers who begin purchasing seed and for the private seed research sector.

description: As part of an International consortium aiming at the characterization by NMR of the proteins of the SARS-CoV-2 virus, we have obtained the virtually complete assignment of the backbone atoms of the non-structural protein nsp9. This small (12 kDa) protein is encoded by ORF1a, binds to RNA and seems to be essential for viral RNA synthesis. The crystal structures of the SARS-CoV-2 protein and other homologues suggest that the protein is dimeric as also confirmed by analytical ultracentrifugation and dynamic light scattering. Our data constitute the prerequisite for further NMR-based characterization, and provide the starting point for the identification of small molecule lead compounds that could interfere with RNA binding and prevent viral replication.

description: Utilizing form factors calculated within the light-cone sum rules, we have evaluated the decay branching ratios of $B_s\to ϕγ$ and $B_s\to ϕ\ell^+\ell^-$ in a single universal extra dimension model (UED), which is viewed as one of the alternative theories beyond the standard model (SM). For the decay $B_s \to ϕ\ell^+\ell^-$, the dilepton invariant mass spectra, the forward-backward asymmetry, and double lepton polarization are also calculated. For each case, we compared the obtained results with predictions of the SM. In lower values of the compactification factor 1/R, the only parameter in this model, we see the considerable discrepancy between the UED and SM models. However, when 1/R increases, the results of UED tend to diminish and at $1/R = 1000 \mathrm{GeV}$, two models have approximately the same predictions. Compared with data from CDF of $B_s \to ϕμ^+ μ^-$, the 1/R tends to be larger than $350 \mathrm{GeV}$. We also note that the zero crossing point of the forward-backward asymmetry is become smaller, which will be an important plat to prob the contribution from the extra dimension model. The results obtained in this work will be very useful in searching new physics beyond SM. Moreover, the order of magnitude for branching ratios shows a possibility to study these channels at the Large Hadron Collider (LHC), CDF and the future super-B factory.

description: We fabricated a large number of single and bilayer graphene transistors and carried out a systematic experimental study of their low-frequency noise characteristics. A special attention was given to determining the dominant noise sources in these devices and the effect of aging on the current-voltage and noise characteristics. The analysis of the noise spectral density dependence on the area of graphene channel showed that the dominant contributions to the low-frequency electronic noise come from the graphene layer itself rather than from the contacts. Aging of graphene transistors due to exposure to ambient for over a month resulted in substantially increased noise attributed to the decreasing mobility of graphene and increasing contact resistance. The noise spectral density in both single and bilayer graphene transistors either increased with deviation from the charge neutrality point or depended weakly on the gate bias. This observation confirms that the low-frequency noise characteristics of graphene transistors are qualitatively different from those of conventional silicon metal-oxide-semiconductor field-effect transistors.

description: We present results of monomer-resolved Monte Carlo simulations for a system of amphiphilic dendrimers of second generation. Our investigations validate a coarse-grained level description based on the zero-density limit effective pair-interactions for low and intermediate densities, which predicted the formation of stable, finite aggregates in the fluid phase. Indeed, we find that these systems form a homogeneous fluid for low densities, which on increasing the density spontaneously transforms into a fluid of clusters of dendrimers. Although these clusters are roughly spherical in nature for intermediate densities, also more complex structures are detected for the highest densities considered.

description: From January to June 2018, two ongoing hepatitis A outbreaks affected travellers returning from Morocco and cases in Europe without travel history, resulting in 163 patients in eight European countries. Most interviewed travel-related cases were unaware of the hepatitis A risk in Morocco. Molecular analysis revealed two distinct hepatitis A virus (HAV) strains (subgenotype IA DK2018_231; subgenotype IB V18–16428). Vaccination recommendations should be emphasised to increase awareness among non-immune travellers to Morocco and HAV-endemic countries.
"It's nice to see old friends again" : family photographs, 'advice', and archival power in a Northern Coast Salish community
Creators: name: Solomonian, Adam Arthur
Publisher: name: University of British Columbia
Year: 2018

description: Photography has a rich and complex past and present among the shíshálh Coast Salish, a self-governing Indigenous Nation on British Columbia’s southern Northwest Coast. This dissertation explores the multiple ways in which photography intersects with contemporary shíshálh (pronounced sheesh-ath) lives. I argue that, far from being an imposed colonial technology, photography is localized in unique, transformative ways. Drawing on James L. Hevia’s (2009) notion of the “photography complex,” I examine the key ways through which photography is culturally active and activated. This begins with locating photography within the complex that is “family” in shíshálh territory. I then move to a discussion of the relationship between photography and cultural memory—as both oral history-telling and public performance. Next, I consider how photographs operate as contact zones between shíshálh peoples and others. Finally, I explore the ways through which photographs are transformed by, in particular, digital preservation and its relationship to more analogue, familial forms of photographic sociality.

Orbital motion of the young brown dwarf companion TWA 5 B

description: With more adaptive optics images available, we aim at detecting orbital motion for the first time in the system TWA 5 A+B. We measured separation and position angle between TWA 5 A and B in each high-resolution image available and followed their change in time, because B should orbit around A. The astrometric measurement precision is about one milli arc sec. With ten year difference in epoch, we can clearly detect orbital motion of B around A, a decrease in separation by ~ 0.0054 arc sec per year and a decrease in position angle by ~ 0.26 degrees per year. TWA 5 B is a brown dwarf with ~ 25 Jupiter masses (Neuhäuser et al. 2000), but having large error bars (4 to 145 Jupiter masses, Neuhäuser et al. 2009). Given its large projected separation from the primary star, ~ 86 AU, and its young age ~ 10 Myrs), it has probably formed star-like, and would then be a brown dwarf companion. Given the relatively large changes in separation and position angle between TWA 5 A and B, we can conclude that they orbit around each other on an eccentric orbit. Some evidence is found for a curvature in the orbital motion of B around A - most consistent with an elliptic (e=0.45) orbit. Residuals around the best-fit ellipse are detected and show a small-amplitude (~ 18 mas) periodic sinusoid with ~ 5.7 yr period, i.e., fully consistent with the orbit of the inner close pair TWA 5 Aa+b. Measuring these residuals caused by the photocenter wobble - even in unresolved images - can yield the total mass of the inner pair, so can test theoretical pre-main sequence models.

description: Purpose: To present and evaluate Dafne (deep anatomical federated network), a freely available decentralized, collaborative deep learning system for the semantic segmentation of radiological images through federated incremental learning. Materials and Methods: Dafne is free software with a client-server architecture. The client side is an advanced user interface that applies the deep learning models stored on the server to the user's data and allows the user to check and refine the prediction. Incremental learning is then performed at the client's side and sent back to the server, where it is integrated into the root model. Dafne was evaluated locally, by assessing the performance gain across model generations on 38 MRI datasets of the lower legs, and through the analysis of real-world usage statistics (n = 639 use-cases). Results: Dafne demonstrated a statistically improvement in the accuracy of semantic segmentation over time (average increase of the Dice Similarity Coefficient by 0.007 points/generation on the local validation set, p < 0.001). Qualitatively, the models showed enhanced performance on various radiologic image types, including those not present in the initial training sets, indicating good model generalizability. Conclusion: Dafne showed improvement in segmentation quality over time, demonstrating potential for learning and generalization.

description: M31 globular cluster B379 is the first extragalactic cluster, the age of which was determined by main-sequence photometry. In this method, the age of a cluster is obtained by fitting its CMD with stellar evolutionary models. However, different stellar evolutionary models use different parameters of stellar evolution, such as range of stellar masses, different opacities and equations of state, and different recipes, and so on. So, it is interesting to check whether different stellar evolutionary models can give consistent results for the same cluster. Brown et al. (2004a) constrained the age of B379 by comparing its CMD with isochrones of the 2006 VandenBerg models. Using SSP models of BC03 and its multi-photometry, Ma et al. (2007) independently determined the age of B379, which is in good agreement with the determination of Brown et al. (2004a). The BC03 models are calculated based on the Padova evolutionary tracks. It is necessary to check whether the age of B379 which, being determined based on the Padova evolutionary tracks, is in agreement with the determination of Brown et al. (2004a). So, in this paper, we re-determine its age using isochrones of the Padova stellar evolutionary models. In addition, the metal abundance, the distance modulus, and the reddening value for B379 are also determined in this paper. The results obtained in this paper are consistent with the previous determinations, which including the age obtained by Brown et al. (2004a). So, this paper confirms the consistence of the age scale of B379 between the Padova isochrones and the 2006 VandenBerg isochrones, i.e. the results' comparison between Brown et al. (2004a) and Ma et al. (2007) is meaningful. The results obtained in this paper are: the metallicity [M/H]=-0.325, the age $τ=11.0\pm1.5$ Gyr, the reddening value E(B-V)=0.08, and the distance modulus $(m-M)_{0}=24.44\pm0.10$.

description: The evolution of galaxies is influenced by the environment in which they reside. This effect should be strongest for the least-mass and -luminosity galaxies. To study dwarf galaxies in extremely low density environments we have compiled a deep catalogue of dwarf galaxies in the nearby Lynx-Cancer void. This void hosts some of the most metal-poor dwarfs known to date. It borders the Local Volume at the negative supergalactic Z (SGZ) coordinates and has the size of more than 16 Mpc. With a distance to its centre of only 18 Mpc it is close enough to allow the search for the faintest dwarfs. Within the void 75 dwarf (-11.9 > M_B > -18.0) and 4 subluminous (-18.0 > M_B > -18.4) galaxies have been identified. We present the parameters of the void galaxies and give a detailed analysis of the completeness of the catalogue as a function of magnitude and surface brightness. The catalogue appears almost complete to M_B < -14 mag, but misses part of the fainter low surface brightness (LSB) face-on galaxies. This sample of void galaxies builds the basis of forthcoming observational studies that will give insight into the main stellar population, HI-mass-to-light ratio, metallicity and age for comparison with dwarfs in higher density regions. We briefly summarize the information on the unusual objects in the void and conclude that their concentration hints that voids are environments that are favourable for finding and studying unevolved dwarf galaxies.

description: A numerical method for generating the state-feedback control law associated with constant-setpoint infinite-horizon nonlinear optimal control problems is presented. The method is general, easily implemented, does not need manually tuned parameters, and inherently verifies the convergence of the control law to the desired setpoint. This paper defines the numerical method, which is based on dynamic programming and the successive approximation method, derives the relevant underlying mathematical properties, and validates the numerical method with representative examples.

description: Consider a compact Kähler manifold endowed with a prequantum bundle. Following the geometric quantization scheme, the associated quantum spaces are the spaces of holomorphic sections of the tensor powers of the prequantum bundle. In this paper we construct an asymptotic representation of the prequantum bundle automorphism group in these quantum spaces. We estimate the characters of these representations under some transversality assumption. The formula obtained generalizes in some sense the Lefschetz fixed point formula for the automorphisms of the prequantum bundle preserving its holomorphic structure. Our results will be applied in two forthcoming papers to the quantum representation of the mapping class group.

description: Automated software verification is a very active field of research which has made enormous progress both in theoretical and practical aspects. Recently, an important amount of research effort has been put into applying these techniques on top of mainstream programming languages. These languages typically provide powerful features such as reflection, aliasing and polymorphism which are handy for practitioners but, in contrast, make verification a real challenge. In this work we present Pest, a simple experimental, while-style, multiprocedural, imperative programming language which was conceived with verifiability as one of its main goals. This language forces developers to concurrently think about both the statements needed to implement an algorithm and the assertions required to prove its correctness. In order to aid programmers, we propose several techniques to reduce the number and complexity of annotations required to successfully verify their programs. In particular, we show that high-level iteration constructs may alleviate the need for providing complex loop annotations.

Essays in political economy and on networks
Creators: name: Canen, Nathan Joseph
Publisher: name: University of British Columbia
Year: 2018

description: This thesis studies topics in political economy and the economics of networks. In Chapter 2, we present and structurally estimate a model of endogenous network formation and legislative activity of politicians. Employing data on social and legislative effort of members of the 105th-110th U.S. Congresses (1997-2009), we find that there are substantial complementarities between the efforts of politicians, both within and across parties. Chapter 3 considers the econometrics of incomplete information games on networks. This chapter develops a tractable empirical model of linear interactions where each agent, after observing part of his neighbors' types, not knowing the full network of how information is transmitted, uses linear best responses. This allows the researcher to perform asymptotic inference without having to observe all the players in the game or having to know precisely the sampling process. The usefulness of this procedure is shown with an application to the provision of public goods across municipalities in Colombia. Chapter 4 studies the sources of party polarization in the U.S. Congress. Polarization is not just the result of changes in the ideology of individual legislators, but also of changes in the ability of political parties to discipline (whip) their members and of the deliberate agenda setting by their leadership. This chapter evaluates quantitatively the importance of these three components in driving polarization through a novel identification approach based on previously untapped whip count data and a structural model of legislative activity. In the final chapter, I turn my attention to the voters' side in political economy models. Surveys, polling data and media reports indicate that voters often choose whom to vote for at different stages in the political campaign. I develop a model of costly information acquisition that rationalizes these observations. The model implies a key tradeoff between the cost of acquiring information, and the gain such information brings. Under this framework, I show that information blackouts (i.e. forbidding release of campaigning or polling information before the election) generates welfare losses of around 1-2%.

description: In this paper, we give estimators of the frequency, amplitude and phase of a noisy sinusoidal signal with time-varying amplitude by using the algebraic parametric techniques introduced by Fliess and Sira-Ramirez. We apply a similar strategy to estimate these parameters by using modulating functions method. The convergence of the noise error part due to a large class of noises is studied to show the robustness and the stability of these methods. We also show that the estimators obtained by modulating functions method are robust to "large" sampling period and to non zero-mean noises.

description: We show that backflow correlations in the variational wave function for the Hubbard model greatly improve the previous results given by the Slater-Jastrow state, usually considered in this context. We provide evidence that, within this approach, it is possible to have a satisfactory connection with the strong-coupling regime. Moreover, we show that, for the Hubbard model on the lattice, backflow correlations are essentially short range, inducing an effective attraction between empty (holons) and doubly occupied sites (doublons). In presence of frustration, we report the evidence that the metal to Mott-insulator transition is marked by a discontinuity of the double occupancy, together with a similar discontinuity of the kinetic term that does not change the number of holons and doublons, while the other kinetic terms are continuous across the transition. Finally, we show the estimation of the charge gap, obtained by particle-hole excitations {\it à la Feynman} over the ground-state wave function.

description: There is a mathematical analogy between the propagation of fields in a general relativistic space-time and long (shallow water) surface waves on moving water. Hawking argued that black holes emit thermal radiation via a quantum spontaneous emission. Similar arguments predict the same effect near wave horizons in fluid flow. By placing a streamlined obstacle into an open channel flow we create a region of high velocity over the obstacle that can include wave horizons. Long waves propagating upstream towards this region are blocked and converted into short (deep water) waves. This is the analogue of the stimulated emission by a white hole (the time inverse of a black hole), and our measurements of the amplitudes of the converted waves demonstrate the thermal nature of the conversion process for this system. Given the close relationship between stimulated and spontaneous emission, our findings attest to the generality of the Hawking process.

description: This work concerns asymptotical stabilisation phenomena occurring in the moduli space of sections of certain algebraic families over a smooth projective curve, whenever the generic fibre of the family is a smooth projective Fano variety, or not far from being Fano.
 We describe the expected behaviour of the class, in a ring of motivic integration, of the moduli space of sections of given numerical class. Up to an adequate normalisation, it should converge, when the class of the sections goes arbitrarily far from the boundary of the dual of the effective cone, to an effective element given by a motivic Euler product. Such a principle can be seen as an analogue for rational curves of the Batyrev-Manin-Peyre principle for rational points.
 The central tool of this article is the property of equidistribution of curves. We show that this notion does not depend on the choice of a model of the generic fibre, and that equidistribution of curves holds for smooth projective split toric varieties. As an application, we study the Batyrev-Manin-Peyre principle for curves on a certain kind of twisted products.

description: The objective of this thesis is to conduct a comprehensive study that applies topic modeling to a corpus of Latin literature and to assess how topic models, through their capacity to predict latent thematic structures and patterns, can enrich the understanding of this vast and diverse literary tradition.

The results demonstrate that the neural topic models, trained on the datasets considered, effectively predict coherent and interpretable sets of topics, showcasing their potential for examining the thematic structures of ancient texts. Indeed, the topics obtained are thoroughly analyzed from a literary standpoint, offering an innovative way to interpret key developments in the history of Latin literature and revealing new dimensions in the works of the authors included in the corpus.
Retrospective schooling reflections among young adults with pediatric-onset inflammatory bowel disease : an interpretative phenomenological analysis
Creators: name: Fuchs, Chantalle Marie
Publisher: name: University of British Columbia
Year: 2018

description: Students with Inflammatory Bowel Disease (IBD) face physical, psychological, social, and educational challenges (e.g., inadequate support from teachers, interrupted attendance and engagement in instruction) that can negatively impact learning trajectories. However, researchers have reported that individuals with pediatric-onset IBD do not demonstrate negative long-term outcomes as many appear to be academically successful upon reaching adulthood. It is unclear why this trend has emerged in recent literature. In this study, the lived-experience of seven young adults with pediatric-onset IBD were examined. Participants were asked to retrospectively reflect on how they navigated living with IBD while also attending school, learning academic concepts, and navigating relationships with teachers and peers. The Interpretative Phenomenological Analysis (IPA) methodological framework was used to guide this investigation. To enhance the credibility and trustworthiness of the findings, employed strategies included: prolonged engagement, reflective journaling, member checks, and measuring the re-occurrence of experience across cases. Six super-ordinate themes and corresponding subthemes emerged from the interviews. IBD Related Experience provided contextual information about participants’ diagnostic process, physical symptoms, mental health concerns, and key sources of stress. Coping Strategies outlined information about individualized medical and holistic treatments used to manage symptoms. Educational Implications revealed participants experienced educational successes in addition to educational challenges and greater levels of difficulty after transitioning to university level programs. Educational Accommodations included formal and informal accommodations and personally developed academic strategies used to overcome educational challenges. Processes of Normalization depicted participants’ journey from experiencing feelings of embarrassment, finding connections with others, and working towards establishing a “new normal.” Social Interactions involved participants keeping their diagnosis private or disclosing to others. After disclosing, participants experienced positive and negative interactions from others. Overall, these participants were academically high achieving and experienced successful educational outcomes. This conclusion (a) likely offers a realistic description of what some students with IBD experience while in school (i.e., mixed experience of successes and challenges) and (b) supported recent researchers who have argued that students with IBD experience long-term educational success. Limitations, strengths, and implications associated with the study along with recommendations for future directions are discussed.

description: We present a power spectrum analysis of the Herschel-SPIRE observations of the Polaris flare, a high Galactic latitude cirrus cloud midway between the diffuse and molecular phases. The SPIRE images of the Polaris flare reveal for the first time the structure of the diffuse interstellar medium down to 0.01 parsec over a 10 square degrees region. These exceptional observations highlight the highly filamentary and clumpy structure of the interstellar medium even in diffuse regions of the map. The power spectrum analysis shows that the structure of the interstellar medium is well described by a single power law with an exponent of -2.7 +- 0.1 at all scales from 30" to 8 degrees. That the power spectrum slope of the dust emission is constant down to the SPIRE angular resolution is an indication that the inertial range of turbulence extends down to the 0.01 pc scale. The power spectrum analysis also allows the identification of a Poissonian component at sub-arcminute scales in agreement with predictions of the cosmic infrared background level at SPIRE wavelengths. Finally, the comparison of the SPIRE and IRAS 100 micron data of the Polaris flare clearly assesses the capability of SPIRE in maping diffuse emission over large areas.

Bayesian inference for double Pareto lognormal queues

description: In this article we describe a method for carrying out Bayesian estimation for the double Pareto lognormal (dPlN) distribution which has been proposed as a model for heavy-tailed phenomena. We apply our approach to estimate the $\mathit{dPlN}/M/1$ and $M/\mathit{dPlN}/1$ queueing systems. These systems cannot be analyzed using standard techniques due to the fact that the dPlN distribution does not possess a Laplace transform in closed form. This difficulty is overcome using some recent approximations for the Laplace transform of the interarrival distribution for the $\mathit{Pareto}/M/1$ system. Our procedure is illustrated with applications in internet traffic analysis and risk theory.

Formal Verification of Voting Schemes

description: Fundamental trust and credibility in democratic systems is commonly established through the existence and execution of democratic elections. The vote-counting of an election, usually formalised by a voting scheme, essentially boils
down to a mechanism that aggregates individual preferences of the voters to reach a decision. For this matter, there are various differing voting schemes in use throughout the world, commonly based on high expectations and means to ensure a sensible democratic process. However, incidents such as the ruling by the German federal constitutional court which led to a change of the German legislation in 2013 manifest that it is difficult for a voting scheme to meet these legitimate expectations. In fact, there is no general notion of correctness for a voting scheme and thus no  universal mechanism as shown in Kenneth J. Arrow’s Impossibility Theorem in 1951. As a consequence, designing a real-world voting scheme without flaws, which still gives significant democratic guarantees, is a difficult task as a trade-off between desirable properties is non-trivial and error-prone. 
The approach in this thesis is based on the idea to tackle this issue by proposing
an incremental and iterative development process for voting schemes based on
automated formal reasoning methods using program verification.
We analyse two different forms of verification considering their role in this
development process in order to achieve formal correctness of voting schemes.
We perform a comprehensive set of case studies by applying ``medium-weight'' and
``light-weight'' verification techniques.
The ``medium-weight'' approach uses the annotation-based deductive verification
tool VCC based on an auto-active methodology and the ``light-weight''
technique is performed with the bounded model checking tool LLBMC.
Our analysis covers a set of well-known voting schemes combined with a set of
prominent voting scheme criteria.
In addition to giving precise formalisations for these criteria adapted to the
specific voting schemes and tools used, we advance the efficiency of the
``light-weight'' approach by exploiting fundamental symmetric properties.
Furthermore, we investigate on encountered challenges posed by the
auto-active verification methodology, which lies in-between automatic
and interactive verification methodologies, with respect to specific
characteristics in voting schemes and also explore the potential of bounded
verification techniques to produce precise counterexamples in order to enhance
the capability of our envisioned development process to give early feedback.
This thesis gives fundamental insights in general challenges and the potential
of automated formal reasoning with the goal of correct voting schemes.

Nutrients and zooplankton as multiple stressors of phytoplankton communities: evidence from size structure
Creators: name: K.L., Cottingham,
Publisher: name: University of Notre Dame
Year: 2023

description: Anthropogenic alterations of nutrient inputs and food-web structure are two of the primary stressors affecting lake phytoplankton. This paper explores the independent and interactive effects of nutrients and food-web structure (as indexed by zooplankton size) on phytoplankton size structure by fitting time-series models to data from three lakes where both factors have been manipulated. I assessed phytoplankton size structure using three different approaches: small and large size classes, normalized size spectra, and average phytoplankton size. Increased phosphorus loading and increased zooplankton size had positive effects on large phytoplankton, slope of size spectra, and mean phytoplankton size, but negative effects on the relative abundance of small phytoplankton. The absolute abundance of small phytoplankton was increased by increased nutrients and decreased by increased zooplankton size. There was some evidence for nutrient 3 zooplankton interactions, particularly from interlake comparisons which revealed that phytoplankton size structure responded to enrichment in qualitatively similar but quantitatively different ways in lakes with different food webs. Specifically, small phytoplankton increased more strongly with enrichment in lakes with many planktivores and few large zooplankton, while large phytoplankton increased more in lakes with few planktivores and many large zooplankton. Thus, food-web structure may influence the extent to which small vs. large phytoplankton respond to nutrient enrichment. Overall, size structure was an excellent descriptor of shifts in phytoplankton communities following manipulation of nutrient inputs and food-web structure. Size spectra and size classes were highly effective approaches for summarizing size structure; average phytoplankton size was somewhat less effective
