In silico insights into the membrane binding mechanism and role of disulfide bridges in the Solanum tuberosum plant specific insert
Creators: name: Dupuis, John Henry
Publisher: name: University of British Columbia
Year: 2020

description: The Solanum tuberosum plant specific insert (StPSI) has a defensive role in potato plants. The StPSI is expressed alongside an aspartic protease, which is targeted to the acidic central vacuole. It functions at an acidic pH and interacts with the anionic lipids of a membrane. The StPSI contains a set of three highly conserved disulfide bonds that bridge the protein’s helical domains, and their removal leads to enhanced membrane interactions. The present work examined several aspects of the StPSI in dimeric form, including the structure and membrane binding as a function of pH, and the effect of sequential removal of the disulfide bonds and their role in maintaining overall protein tertiary structure. Several glutamic and aspartic acid residues displayed highly perturbed pKa values, however, pH was found to have little, if any, effects on the secondary structure of the StPSI at pH 3.0 or 7.4. Coarse-grained modelling of the StPSI demonstrated poor affinity for neutral or anionic membranes at pH 7.4. Conversely, at pH 3.0, two binding modes were uncovered: Mode 1 (inactive binding) and Mode 2 (active binding). In Mode 2, N- and C-terminal residues of one monomer and numerous polar and basic residues on the second monomer interacted strongly with anionic membranes, accompanied by a re-orientation of the dimer to a more vertical position. These results offer the first examination, at near-atomic resolution, of residues mediating the StPSI-membrane interactions, and allow for the proposal of a possible fusion mechanism. Removal of disulfide bonds did not lead to destabilization of the tertiary structure at either pH 3.0 or 7.4. The StPSI possesses an extensive network of inter-monomer hydrophobic interactions and intra-monomer hydrogen bonds, which stabilize the local secondary structure, leading to a robust association between monomers, regardless of the disulfide bond state. Removal of disulfide bonds did not substantially impact secondary structure, however, they may play an important role in maintaining a less plastic structure within plant cells in order to regulate membrane affinity or targeting.

description: By definition, Population III stars are metal-free, and their protostellar collapse is driven by molecular hydrogen cooling in the gas-phase, leading to large characteristic masses. Population II stars with lower characteristic masses form when the star-forming gas reaches a critical metallicity of 10^{-6} - 10^{-3.5} Z_\odot. We present an adaptive mesh refinement radiation hydrodynamics simulation that follows the transition from Population III to II star formation. The maximum spatial resolution of 1 comoving parsec allows for individual molecular clouds to be well-resolved and their stellar associations to be studied in detail. We model stellar radiative feedback with adaptive ray tracing. A top-heavy initial mass function for the Population III stars is considered, resulting in a plausible distribution of pair-instability supernovae and associated metal enrichment. We find that the gas fraction recovers from 5 percent to nearly the cosmic fraction in halos with merger histories rich in halos above 10^7 solar masses. A single pair-instability supernova is sufficient to enrich the host halo to a metallicity floor of 10^{-3} Z_\odot and to transition to Population II star formation. This provides a natural explanation for the observed floor on damped Lyman alpha (DLA) systems metallicities reported in the literature, which is of this order. We find that stellar metallicities do not necessarily trace stellar ages, as mergers of halos with established stellar populations can create superpositions of t-Z evolutionary tracks. A bimodal metallicity distribution is created after a starburst occurs when the halo can cool efficiently through atomic line cooling.

description: Dimensions of objects in fusion categories are cyclotomic integers, hence number theoretic results have implications in the study of fusion categories and finite depth subfactors. We give two such applications. The first application is determining a complete list of numbers in the interval (2, 76/33) which can occur as the Frobenius-Perron dimension of an object in a fusion category. The smallest number on this list is realized in a new fusion category which is constructed in the appendix written by V. Ostrik, while the others are all realized by known examples. The second application proves that in any family of graphs obtained by adding a 2-valent tree to a fixed graph, either only finitely many graphs are principal graphs of subfactors or the family consists of the A_n or D_n Dynkin diagrams. This result is effective, and we apply it to several families arising in the classification of subfactors of index less then 5.

description: High signal-to-noise (S/N) observations of the QSO PKS 0405-123 (zem = 0.572) with the Cosmic Origins Spectrograph from 1134 to 1796 A with a resolution of 17 km s-1 are used to study the multi-phase partial Lyman limit system (LLS) at z = 0.16716 which has previously been studied using relatively low S/N spectra from STIS and FUSE. The LLS and an associated H I-free broad O VI absorber likely originate in the circumgalactic gas associated with a pair of galaxies at z = 0.1688 and 0.1670 with impact parameters of 116 h70-1 and 99 h70-1. The broad and symmetric O VI absorption is detected in the z = 0.16716 restframe with v = -278 +/- 3 km s-1, log N(O VI) = 13.90 +/- 0.03 and b = 52 +/- 2 km s-1. This absorber is not detected in H I or other species with the possible exception of N V . The broad, symmetric O VI profile and absence of corresponding H I absorption indicates that the circumgalactic gas in which the collisionally ionized O VI arises is hot (log T ~ 5.8-6.2). The absorber may represent a rare but important new class of low z IGM absorbers. The LLS has strong asymmetrical O VI absorption with log N(O VI) = 14.72 +/- 0.02 spanning a velocity range from -200 to +100 km s-1. The high and low ions in the LLS have properties resembling those found for Galactic highly ionized HVCs where the O VI is likely produced in the conductive and turbulent interfaces between cool and hot gas.

description: An optical resonator with intracavity Kerr nonlinearity can exhibit dispersive bistability suitable for all-optical switching. With nanophotonic elements it may be possible to achieve attojoule switching energies, which would be very attractive for ultra-low power operation but potentially problematic because of quantum fluctuation-induced spontaneous switching. In this manuscript I derive a quantum-optical model of two Kerr-nonlinear ring resonators connected in a coherent feedback loop, and show via numerical simulation that a properly designed `controller' cavity can significantly reduce the spontaneous switching rate of a bistable `plant' cavity in a completely embedded and autonomous manner.

description: We investigate the hydrodynamic limit for weakly asymmetric simple exclusion processes in crystal lattices. We construct a suitable scaling limit by using a discrete harmonic map. As we shall observe, the quasi-linear parabolic equation in the limit is defined on a flat torus and depends on both the local structure of the crystal lattice and the discrete harmonic map. We formulate the local ergodic theorem on the crystal lattice by introducing the notion of local function bundle, which is a family of local functions on the configuration space. The ideas and methods are taken from the discrete geometric analysis to these problems. Results we obtain are extensions of ones by Kipnis, Olla and Varadhan to crystal lattices.

Possible Origin of the Anomalous Far-infrared Absorption by Small Metal Particles

description: We have carried out the far-infrared transmission measurements on the ligand stabilized Au55 particles dispersed in CsI. We have found that there exists the crossover energy Ec ~ 160 cm -1 (~ 19 meV) beyond which the absorption coefficient recovers the classical electric dipole-like absorption and, hence, the absorption for frequencies higher than Ec is insensitive to the particle size. We propose that the physical origin of the enigmatic anomalous far-IR absorption by small metal particles lies in the absorption arising from the transitions the electrons between the discrete energy levels below Ec on which the particle size independent, classical electric dipole absorption develops for frequencies higher than Ec.
Examination of a new model of genetic counselling and assessing a demographically diverse patient population attending hereditary cancer genetic counselling services
Creators: name: Richardson, Matthew
Publisher: name: University of British Columbia
Year: 2020

description: The popularity of genetic testing and counselling for hereditary cancer syndromes has increased rapidly in the past decade due to a decrease in genetic sequencing costs, increase in public interest, and increase in medically actionable results. As the demand for genetic testing services has increased, the wait times for patients to receive genetic testing and counselling has also increased. In order to increase patient access to genetic testing and counselling, genetics services must examine new genetic counselling models and ensure that historically under-served patient populations are receiving equitable health outcomes. In this thesis I have examined the impact of a new model of genetic counselling termed oncology clinic-based genetic counselling, examined patient demographics at the Hereditary Cancer Program (HCP) in British Columbia Canada, and assessed patient reported outcome measures (PROMs) from patients receiving genetic testing and counselling. I found that oncology clinic-based genetic testing and counselling significantly reduced patient wait times from referral to return of genetic testing results compared to traditional genetic counselling (403 vs 198 days; p < 0.001). Secondly, oncology clinic-based genetic testing and counselling was acceptable to both patients and healthcare providers. Furthermore, I found that all ethnic minority patient populations are under-represented at the HCP, and patients of Asian ethnicity are significantly more likely than patients of European ethnicity to receive a pathogenic variant (p < 0.001) or variant of uncertain significance (p < 0.001) genetic test result. Lastly, from analyzing PROMs from patients attending the HCP I found that patients of self-expressed Asian ethnicity experience increased distress (p = 0.003) and uncertainty (p < 0.001) compared to patients of European ethnicity. These results show that new models for genetic testing and counselling increase patient access by decreasing wait times and are acceptable to patients. As well, ethnic minority patients are underrepresented at the HCP, receive more complicated genetic diagnoses, and experience more negative feelings from genetic testing. In order to increase access to genetic testing and counselling services, increase ethnic minority population participation, and decrease health outcome inequities, new genetic counselling models and the modification of current genetic counselling models are necessary.

description: A model is presented for the quantum transport of electrons, across finite atomic wire nanojunctions between electric leads, at zero bias limit. In order to derive the appropriate transmission and reflection spectra, familiar in the Landauer-Büttiker formalism, we develop the algebraic phase field matching theory (PFMT). In particular, we apply our model calculations to determine the electronic conductance for freely suspended monatomic linear sodium wires (MLNaW) between leads of the same element, and for the diatomic copper-cobalt wires (DLCuCoW) between copper leads on a Cu(111) substrate. Calculations for the MLNaW system confirm the correctness and functionality of our PFMT approach. We present novel transmission spectra for this system, and show that its transport properties exhibit the conductance oscillations for the odd- and even-number wires in agreement with previously reported first-principle results. The numerical calculations for the DLCuCoW wire nanojunctions are motivated by the stability of these systems at low temperatures. Our results for the transmission spectra yield for this system, at its Fermi energy, a monotonic exponential decay of the conductance with increasing wire length of the Cu-Co pairs. This is a cumulative effect which is discussed in detail in the present work, and may prove useful for applications in nanocircuits. Furthermore, our PFMT formalism can be considered as a compact and efficient tool for the study of the electronic quantum transport for a wide range of nanomaterial wire systems. It provides a trade-off in computational efficiency and predictive capability as compared to slower first-principle based methods, and has the potential to treat the conductance properties of more complex molecular nanojunctions.

Exploring learning opportunities in open data use across data literacy levels
Creators: name: Li, Ak Wai
Publisher: name: University of British Columbia
Year: 2020

description: The purpose of this study is to explore learning opportunities for users with different data literacy levels when using open data within an open data portal, with the goal of informing design. An open data portal is a web-based data repository provided by a government to allow the public to find and use open-access government data. Three aspects are investigated: user interactions with the open data portal and associated tools; obstacles faced in interacting with the portal; and learning strategies employed. The City of Vancouver’s open data portal was the study environment. Fourteen university students participated in this remotely administered study which included an assigned task, a think-aloud observational session, a self-completion questionnaire, and a semi-structured interview. There were divvied into high/low data literacy groups based on a self-assessment questionnaire. The video recordings of the think-aloud observational sessions and semi-structured interviews were analyzed using qualitative methods. Participants in the low data literacy group faced more obstacles due to gaps in understanding how to process open data than those in the higher data literacy group. Participants in the high data literacy group mainly faced obstacles in figuring out how to use the unfamiliar data analysis tools in the portal. Some important data processing activities such as evaluating data quality, data wrangling, labeling analyzed findings and data citation, seemed to be lacking across all participants, regardless of their data literacy self-assessment. These results suggest that an open data portal should improve usability to help users learn to use the tools and provide learning tools to help users develop needed data literacy skills to make good use of open data. The findings have implications for the future study of designing learning tools in an open data portal for users with different data literacy levels.

description: We consider the problem of subspace estimation in a Bayesian setting. Since we are operating in the Grassmann manifold, the usual approach which consists of minimizing the mean square error (MSE) between the true subspace $U$ and its estimate $\hat{U}$ may not be adequate as the MSE is not the natural metric in the Grassmann manifold. As an alternative, we propose to carry out subspace estimation by minimizing the mean square distance (MSD) between $U$ and its estimate, where the considered distance is a natural metric in the Grassmann manifold, viz. the distance between the projection matrices. We show that the resulting estimator is no longer the posterior mean of $U$ but entails computing the principal eigenvectors of the posterior mean of $U U^{T}$. Derivation of the MMSD estimator is carried out in a few illustrative examples including a linear Gaussian model for the data and a Bingham or von Mises Fisher prior distribution for $U$. In all scenarios, posterior distributions are derived and the MMSD estimator is obtained either analytically or implemented via a Markov chain Monte Carlo simulation method. The method is shown to provide accurate estimates even when the number of samples is lower than the dimension of $U$. An application to hyperspectral imagery is finally investigated.
Il benessere in classe: il punto di vista dei bambini

description: La mia ricerca qualitativa ha l’intento di scoprire quali siano gli elementi che il bambino ritiene importanti per sentirsi bene in classe, mettendoli in relazione alle azioni del docente e verificando, inoltre, se queste variano a dipendenza del grado scolastico. Per rispondere ai miei interrogativi ho attuato alcune interviste semi-strutturate in due classi (una di II e una di V elementare) ponendo principalmente al bambino la domanda: “cosa ti piace o non ti piace della scuola? e cosa ti fa sentire bene/male a scuola?” Le risposte sono state inserite in alcune categorie generiche in riferimento ad aspetti teorici. Grazie a questo lavoro ho potuto constatare che sono molti i fattori che concorrono alla creazione del benessere personale in classe: le relazioni tra compagni e con il docente, il clima di lavoro, la gestione emotiva, lo stile d’insegnamento del docente e la sua attenzione per i singoli. Inoltre ho potuto confermare l’ipotesi che questi fattori siano diversi a dipendenza del grado scolastico: nel primo ciclo sono emersi bisogni piuttosto primari ed affettivi (maggiormente egocentrici), mentre nel secondo ciclo, piuttosto relazionali e sociali.

description: The degenerate parabolic equation u_t + [u^3(u_xxx + u_x - sin x)]_x=0 models the evolution of a thin liquid film on a stationary horizontal cylinder. It is shown here that for each given mass there is a unique steady state, given by a droplet hanging from the bottom of the cylinder that meets the dry region at the top with zero contact angle. The droplet minimizes the energy and attracts all strong solutions that satisfy certain energy and entropy inequalities. The distance of any solution from the steady state decays no faster than a power law.
description: 26 pages, 6 figures. This is a greatly expanded version of our previous submission [arXiv:1009.4092v1]. The main result on convergence to equilbrium is new, and the bounds on the rate of convergence have been simplified. For the second version, we have changed the title, corrected Lemma 2.3, rewrittenSection 3, and added several references

description: The study examines the factors which stimulate the interest of farmer's children in agricultural practices, in their homes, schools, field, or environment for increase in food production and to alleviate poverty in Asa Local Government Area of Kwara State. The instrument used for data collection was interview schedule and structured questionnaire, collected from 120 children both in their homes and their schools using Kwara state listing frame to randomly select four major towns in the area. it was discovered that 26.7% of the children are within 8-10 years, 30.8% are within 11-13 years, 34.2% are between 14-16 years and 8.3% are between 17&18 years of age. about 90% of the children are from nuclear or extended homes and are in formal schools (either in the primary level or secondary level), while the minority of about 10% or less are from polygamous homes and are in no formal school setting. Majority of the children find agricultural activities such as planting, clearing, weeding, harvesting and livestock rearing more interesting than the post planting or marketing activities. The major factor which arouses their interest in Agriculture is the idea that Agriculture is a profitable business. The correlation analysis value (p<0.05) revealed the significant relationship between the socioeconomic characteristics and the motivating factors.

description: In this work we present the results of studying the optical properties of InGaAs/InGaAlAs semiconductor heterostructures with InGaAs quantum wells grown on an InP substrate in the optical range of 1.55 Î¼m. The results of the influence of impurities on the dependences of the integrated photoluminescence and width of the spectrum on the excitation power density are presented. The dependences of the integrated photoluminescence intensity and width of the spectrum on temperature were obtained and analyzed. It is observed that lowering of the temperature results in a second peak in photoluminescence spectrum for some structures.

description: Magnetic reconnection, a fundamental plasma process associated with a rapid dissipation of magnetic energy, is believed to power many disruptive phenomena in laboratory plasma devices, the Earth magnetosphere, and the solar corona. Traditional reconnection research, geared towards these rather tenuous environments, has justifiably ignored the effects of radiation on the reconnection process. However, in many reconnecting systems in high-energy astrophysics (e.g., accretion-disk coronae, relativistic jets, magnetar flares) and, potentially, in powerful laser plasma and z-pinch experiments, the energy density is so high that radiation, in particular radiative cooling, may start to play an important role. This observation motivates the development of a theory of high-energy-density radiative magnetic reconnection. As a first step towards this goal, we present in this paper a simple Sweet--Parker-like theory of non-relativistic resistive-MHD reconnection with strong radiative cooling. First, we show how, in the absence of a guide magnetic field, intense cooling leads to a strong compression of the plasma in the reconnection layer, resulting in a higher reconnection rate. The compression ratio and the layer temperature are determined by the balance between ohmic heating and radiative cooling. The lower temperature in the radiatively-cooled layer leads to a higher Spitzer resistivity and hence to an extra enhancement of the reconnection rate. We then apply our general theory to several specific astrophysically important radiative processes (bremsstrahlung, cyclotron, and inverse-Compton) in the optically thin regime, for both the zero- and strong-guide-field cases. We derive specific expressions for key reconnection parameters, including the reconnection rate. We also discuss the limitations and conditions for applicability of our theory.

description: The data understanding stage plays a central role in the entire process of data analytics, as it allows the analyst to gain familiarity with the data, identify data quality issues, and discover initial insights into the data before further analysis (Chapman et al., 2000). These tasks become easier in the presence of well-documented background information such as a data dictionary, which is defined as “a centralized repository of information about data such as meaning, relationships to other data, origin, usage, and format” (McDaniel, 1994). However, data dictionaries are often missing or incomplete. In this thesis we focus on inference of data types (both syntactic and semantic), and develop probabilistic approaches that enable the automatic construction of a data dictionary for a given dataset. Unlike existing rule-based methods, our proposed methods allow us to express uncertainty in a principled way and can provide accurate type predictions even for messy datasets with missing and anomalous values. The thesis makes the following contributions: First, we present ptype - a probabilistic generative model that uses Probabilistic Finite-State Machines (PFSMs) to represent data types. By detecting missing and anomalous data, ptype infers syntactic data types accurately and improves over the performance of existing approaches for type inference. Moreover, it offers the advantage of generating weighted predictions when a column of messy data is consistent with more than one type assignment, in contrast to more familiar finite-state machines (e.g., regular expressions). Secondly, we propose ptype-cat which is an extension of ptype for a better detection of the categorical type. ptype treats non-Boolean categorical variables as either integers or strings. By combining the output of ptype and additional features that can indicate whether a column represents a categorical variable or not, ptype-cat can correctly detect the general categorical type (including non-Boolean variables). In addition, we adapt ptype to the task of identifying the values associated with the corresponding categorical variable. Finally, we present ptype-semantics to demonstrate how ptype can be enriched by semantic information. In this regard, we focus on dimension and unit inference, which are respectively the task of identifying the dimension of a data column and the task of identifying the units of its entries. Syntactic type inference methods including ptype do not address these tasks. However, ptype-semantic can extract extra semantic information (such as dimension and unit) about data columns and treat them as either floats or integers rather than strings.
