Undetected but widespread : the cryptic invasion of non-native cattail (Typha) in the Fraser River Estuary
Creators: name: Stewart, Daniel
Publisher: name: University of British Columbia
Year: 2021

description: Invasive species represent a significant and growing threat to biodiversity in ecosystems around the world. Research that can address key knowledge gaps is invaluable, particularly as managers grapple with diminishing time, resources, and data to deal with species invasions. Non-native narrow-leaved cattail (Typha angustifolia) is a wetland invader that has been detected in western Canada’s Fraser River Estuary (FRE) in recent decades, but questions around their degree of establishment, impact, manageability, and the potential emergence of invasive hybrid cattail (Typha x glauca), remain unanswered. This research aimed to address these knowledge gaps, investigating the threat potential of these taxa. Using a spectral analysis of aerial imagery, I found that invasive cattails are widespread, currently occupying approximately 4% of FRE marshes. Though never formally recorded in the FRE, T. x glauca is more abundant than T. angustifolia, and likely went undetected due to its cryptic nature. A species distribution model for invasive cattail predicted that 28% and 21% of the FRE has suitability (establishment and persistence) and susceptibility (risk of colonization when suitable) probabilities of > 50% respectively, indicating this invasion is likely to continue. Restoration projects were invasion hotspots, with proportionally more cattail, susceptible habitat, and suitable habitat than the overall estuary. Vegetation sampling demonstrated that cattail-invaded marshes contained lower richness and diversity than uninvaded habitats. Cattail leaf litter had a significant negative effect on richness and diversity, while ramet density and foliar cover did not, suggesting litter may be an important dominance mechanism behind this invasion. Results from a two-year management experiment suggest these impacts may be counteracted, but not without expending considerable resources. Belowground energy reserves declined in response to cutting, however cattail ramets remained unchanged or increased in abundance. Native plant communities have yet to respond significantly to cutting and litter removal, suggesting that more time may be required for their recovery. I conclude that the extent of this invasion, likelihood of further invasion, and management challenges presented by invasive cattail require a strategic shift towards preventative management approaches, such as surveillance and early eradication in uninvaded high-value habitats, along with restoration designs that inhibit litter accumulation.

A model of the entropy flux and Reynolds stress in turbulent convection

description: We propose a closure model for the transport of entropy and momentum in astrophysical turbulence, intended for application to rotating stellar convective regions. Our closure model is first presented in the Boussinesq formalism, and compared with laboratory and numerical experimental results on Rayleigh-Benard convection and Homogeneous Rayleigh-Benard convection. The predicted angular momentum transport properties of the turbulence in the slowly rotating case recover the well-known Lambda-effect, with an amplitude uniquely related to the convective heat flux. The model is then extended to the anelastic case as well as the fully compressible case. In the special case of spherical symmetry, the predicted radial heat flux is equivalent to that of mixing-length theory. For rotating stars, our model describes the coupled transport of heat and angular momentum, and provides a unified formalism in which to study both differential rotation and thermal inhomogeneities in stellar convection zones.

Formation of Barium Stars constrained by Gaia parallaxes
Creators: name: Escorza, Ana
name: Jorissen, Alain
Publisher: name: Zenodo
Year: 2019

description: In this presentation I showed how, thanks to Gaia and other high quality data, we have obtained information about the masses of the unseen white-dwarf (WD) companions of some Barium (Ba) stars. Barium stars are chemically peculiar stars that were polluted by a former Asymptotic-Giant-Branch (AGB) companion via binary interaction. This companion is now a dim white dwarf that we can not directly detect and our goal is to obtain as much information about this binaries as we can from observations of different kinds. Barium stars are a prototypical family of post-mass-transfer systems, and a better understanding of their formation will teach us about interaction processes in low- and intermediate-mass binary systems in general.

We determined the evolutionary masses of the visible components, the barium stars, for more than 100 of these systems. To do this, we combined stellar parameters from high-resolution spectra, MARCS model atmospheres,, Gaia DR2 distances and evolutionary tracks. Additionally, we constrained the orbital parameters of these systems thanks to several long-term radial-velocity monitoring programs. As a result of the orbital modeling, we obtained the mass functions of the systems, which relate the masses of the two components with the orbital parameters. Combining these mass functions with the evolutionary masses and assuming a distribution of the orbital inclinations on the sky, we derived the mass distributions for the unseen WD companions. We obtained a wide range of WD masses and some conclusions that might be hints about the formation of Ba stars, for example, the indication that WD companions of mildly-enhanced barium stars are somehow less massive than those of strongly-enhanced barium stars.

The orbital inclinations are the biggest uncertainty, preventing us from obtaining absolute masses for the secondary stars of these systems, and assuming a distribution of orbital inclinations is the best we can do right now. However, astrometric orbits can remove this uncertainty, and that is why we are looking forward to future Gaia data releases.

description: A recent paper [J. Chem. Phys. 132, 134705 (2010)] illustrated the potential of the van der Waals density functional (vdW-DF) method [Phys. Rev. Lett. 92, 246401 (2004)] for efficient first-principle accounts of structure and cohesion in molecular crystals. Since then, modifications of the original vdW-DF version (identified as vdW-DF1) has been proposed, and there is also a new version called vdW-DF2 [ArXiv 1003.5255], within the vdW-DF framework. Here we investigate the performance and nature of the modifications and the new version for the binding of a set of simple molecular crystals: hexamine, dodecahedrane, C60, and graphite. These extended systems provide benchmarks for computational methods dealing with sparse matter. We show that a previously documented enhancement of non-local correlations of vdW-DF1 over an asymptotic atom-based account close to and a few A, beyond binding separation persists in vdW-DF2. The calculation and analysis of the binding in molecular crystals requires appropriate computational tools. In this paper, we also present details on our real-space parallel implementation of the vdW-DF correlation and on the method used to generate asymptotic atom-based pair potentials based on vdW-DF.

description: In this work, we report the customized design and development of a fully automated measurement system to characterize the temperature-dependent properties of microscale thermoelectric devices. The featured system can characterize the devices up to a dimension of 8.79 × 8.79 mm2 in an atmospheric environment. Commercially available bismuth telluride-based thermoelectric modules (both thermoelectric generator and thermoelectric cooler) are used to validate the feasibility and accuracy of the developed system. Their performance data is analysed and compared with the available manufacturer datasheet. The measured data from these devices are found to be in good agreement with the anticipated values and showed an acceptable deviation of less than 4% in the output performances. The developed setup is simple to operate and suitable for performance evaluation of both macro and micro-thermoelectric devices. The system accurately reproduces application conditions the module may be subjected to in a real-world environment.
The first Fermi multifrequency campaign on BL Lacertae: characterizing the low-activity state of the eponymous blazar

description: We report on observations of BL Lacertae during the first 18 months of Fermi-LAT science operations and present results from a 48-day multifrequency coordinated campaign from 2008 August 19 to 2008 October 7. The radio to gamma-ray behavior of BL Lac is unveiled during a low activity state thanks to the coordinated observations of radio-band (Metsahovi and VLBA), near-IR/optical (Tuorla, Steward, OAGH and MDM) and X-ray (RXTE and Swift) observatories. No variability was resolved in gamma-rays during the campaign, and the brightness level was 15 times lower than the level of the 1997 EGRET outburst. Moderate and uncorrelated variability has been detected in UV and X-rays. The X-ray spectrum is found to be concave indicating the transition region between the low and high energy component of the spectral energy distribution (SED). VLBA observation detected a synchrotron spectrum self-absorption turnover in the innermost part of the radio jet appearing to be elongated and inhomogeneous, and constrained the average magnetic field there to be less than 3 G. Over the following months BL Lac appeared variable in gamma-rays, showing flares (in 2009 April and 2010 January). There is no evidence for correlation of the gamma-rays with the optical flux monitored from the ground in 18 months. The SED may be described by a single zone or two zone synchrotron self-Compton (SSC) model, but a hybrid SSC plus external radiation Compton (ERC) model seems preferred based on the observed variability and the fact that it provides a fit closest to equipartition.

Entrepreneurial posture in communications : entrepreneurial orientation (EO) analysis in financial communications with computer-assisted text analysis combined with EO custom dictionaries, natural language processing, and machine learning
Creators: name: Henderson, John David
Publisher: name: University of British Columbia
Year: 2021

description: Given the emergence of new automated text-based measurement and machine learning analytical techniques such as Natural Language Processing (NLP) and Topic Modelling, which serve as research analytical methodologies, there is growing interest in their use and application to business scenarios as well as theory development. Issues arise, however, as existing theory may not be properly reflected in such novel methods, such as computer-assisted text analysis (CATA), natural language processing, and topic modeling. This research joins one such conceptual debate regarding entrepreneurial orientation (EO), a psychometric evaluation of a firm’s behavioral nature related to risk-taking, innovativeness, proactiveness, autonomy, and competitive aggressiveness. It has been recently argued that entrepreneurial words, which form the text-based EO measurement, alone are not necessarily aligned with EO concepts as a behavioral construct (Covin & Wales, 2018). This research proposes a novel extension to EO as a messaging construct called entrepreneurial posture (EP) within an Entrepreneurial Posture in Communications (EPIC) framework, where the moderating influence between EO and Firm Performance (FP) is conceptualized as candor, the quality of being honest and straightforward in attitude and speech. Methodological segmentation by natural language processing (NLP) and machine learning topic modelling techniques is also explored in this research. Topic model segmentation identified communities with differing EO to FP profiles, which supports the theoretical view that firm communities differ in candor profiles. Results from this research demonstrates unique EP expression in firms’ communications with respect to numerous accounting and market measures and across time. The results also identified communities with differing EO to FP conceptual relationships, where specific candor differences were suggested. Conclusions drawn suggest that the combined assessment of EP and candor, using automated text-based analysis exclusively, provides predictive insights in keeping with strategic posture. Methodologically, the novel application of NLP and machine learning topic modelling presented in this research improved the proportion of explain variance in the EO to Firm Performance model from 0.04 to 0.21, an affect size substantially higher than typically presented in EO literature.
Stability of gravity-scalar systems for domain-wall models with a soft wall

description: We show that it is possible to create an RS soft-wall model, a model with a compact extra dimension, without using fundamental branes. All that is required are bulk scalar fields minimally coupled to gravity. Of crucial importance is the stability of the size of the extra dimension. Without branes, one cannot easily implement the Goldberger-Wise mechanism, and instead it must be shown that the scalar configuration is stable in its own right. We use the superpotential approach for generating solutions, the so called 'fake supergravity' scenario, and show that configurations generated in such a way are always free of tachyonic modes. Furthermore, we show that the model is also free of zero modes (in the spin-0 sector) if all the scalars have odd parity. We discuss the hierarchy problem in soft-wall models, and applications of our analysis to the AdS/QCD correspondence.

description: Motivated by recent experiments [Ward et al., Nature Nanotech. 5, 732 (2010)], we present here a theoretical analysis of the optical response of sharp gold electrodes separated by a subnanometer gap. In particular, we have used classical finite difference time domain simulations to investigate the electric field distribution in these nanojunctions upon illumination. Our results show a strong confinement of the field within the gap region, resulting in a large enhancement compared to the incident field. Enhancement factors exceeding 1000 are found for interelectrode distances on the order of a few angstroms, which are fully compatible with the experimental findings. Such huge enhancements originate from the coupling of the incident light to the evanescent field of hybrid plasmons involving charge density oscillations in both electrodes.

description: We construct bi-local interpolating field operators for baryons consisting of three quarks with two flavors, assuming good isospin symmetry. We use the restrictions following from the Pauli principle to derive relations/identities among the baryon operators with identical quantum numbers. Such relations that follow from the combined spatial, Dirac, color, and isospin Fierz transformations may be called the (total/complete) Fierz identities. These relations reduce the number of independent baryon operators with any given spin and isospin. We also study the Abelian and non-Abelian chiral transformation properties of these fields and place them into baryon chiral multiplets. Thus we derive the independent baryon interpolating fields with given values of spin (Lorentz group representation), chiral symmetry ($U_L(2) \times U_R(2)$ group representation) and isospin appropriate for the first angular excited states of the nucleon.

Simultaneous seismic modelling of multiple stars using correlated parameters

Publisher: name: Zenodo

description: The asteroseimsology of individual solar-like oscillators generally allows more precise inferences about many stellar model parameters than with only non-seismic constraints. Some of these parameters (e.g. the mass and age) are fundamental physical properties of the star but some (e.g. the mixing-length parameter for near-surface convection) represent uncertainty in the physics of our stellar models. Most asteroseismic modelling takes these parameters as free or fixes them to some value, motivated by other constraints. I will show how one can introduce correlations between the parameter values for different stars to quantify our expectation that, even if we don’t know exactly what values these non-fundamental parameters take, we don’t expect them to differ much between similar stars. e.g. if two stars have surface gravities and effective temperatures that differ by 0.05 dex and 50 K, respectively, they probably have similar mixing-length parameters, too. I demonstrate this concept using a binary star system observed in Kepler, in which I also experiment with how close we expect the stars’ ages and compositions to be. In principle, the method is not limited to binary stars and, the more efficient the model-fitting for a single star, the more stars can be included in a simultaneous fit that constrains how the non-fundamental parameters vary across a (sub)sample
 of solar-like oscillators, like the sample that PLATO will study.

description: We report a combined electronic transport and structural characterization study of small carbon nanotube bundles in field-effect transistors (FET). The atomic structures of the bundles are determined by electron diffraction using an observation window built in the FET. The single-walled nanotube bundles exhibit electrical transport characteristics sensitively dependent on the structure of individual tubes, their arrangements in the bundle, deformation due to intertube interaction, and the orientation with respect to the gate electric field. Our ab-initio simulation shows that tube deformation in the bundle induces a bandgap opening in a metallic tube. These results show the importance of intertube interaction in electrical transport of bundled nanotubes.

description: HARPS3 could be a key tool in the radial velocity (RV) follow-up of PLATO planetary candidates. HARPS3 is an R≈115,000, fibre-fed, Echelle spectrograph with an operational wavelength range of 380–690 nm and a deployable/integrated, dual-beam, full-Stokes polarimeter. The spectrograph is designed to be able to detect ~Earth-mass exoplanets with orbital periods of 100+ days around G- and K-type stars and will utilise a robust series of stability measures in order to achieve an instrument stability of ∼ 10cm/s; enabling the study of lower mass planets than previous generation instruments. The spectrograph will be coupled to the upgraded and roboticized 2.54m Isaac Newton Telescope (INT), where up to 50% open-time is available on HARPS3. Furthermore, and of special note, an automated scheduler will enable flexible scheduling of observations, which will be interleaved with the rest of the night’s observations, enabling efficient observing strategies that maximise the use of an observers allocated telescope time. HARPS3 will also utilise a trusted and proven data-reduction pipeline for straightforward and reliable extraction of radial velocity data. In this talk, we discuss the design, specifications and capabilities of HARPS3@INT and how these could provide favourable opportunities for RV follow-up of PLATO targets.

description: Il presente lavoro prende avvio con la spiegazione dettagliata delle motivazioni personali che hanno condotto la candidata ad inquadrare - in un contesto allargato ad alcune scuole medie del Cantone - la propria ricerca-azione in merito alla didattica della grammatica. Dopo il capitolo in cui vengono definiti l’ambito teorico di riferimento e la situazione attuale legata all’uso della lingua italiana da parte degli allievi di scuola media - con un accenno alle difficoltà che il docente incontra nell’insegnare grammatica - viene presentata la modalità di realizzazione e di somministrazione del questionario, a cui hanno risposto ventisette docenti di alcune sedi del cantone, nel quale si è indagato in merito all’uso del manuale di grammatica, alla scelta del metodo didattico di insegnamento della stessa e alla conoscenza del contesto attuale . Alla parte contenente le riflessioni in relazione ad alcuni dati raccolti tramite i questionari, seguono un approfondimento delle stesse, tramite il confronto avuto con tre docenti intervistati sul medesimo argomento, e le conclusioni nelle quali la candidata esplicita i risultati raggiunti al termine della ricerca e le ricadute effettive che queste “scoperte” avranno in concreto sulla sua pratica didattica.

description: Spin-dependent tunneling of 2D electron through two different types of barriers is studied. In the first case barrier is a single delta-potential located in a medium with presence of spin-orbit interaction (SOI). In the second case barrier has a bit more complicated structure: it includes two delta-potentials separated by medium with SOI. This compound barrier is located in medium without SOI. The effective spin-dependent Hamiltonian approximation is used for a theoretical investigation of the influence of electron spin on the tunneling probability. It is shown that spin-orbit splitting in the dispersion relation for 2D electrons in semiconductor structure can provide the dependence of the tunneling transmission probability on the electron-spin polarization without additional magnetic field.

description: Nuclear chirality has been intensively studdied for the last several years in the context of experimental as well as theoretical approach. Characteristic gamma selection rules have been predicted for the strong chiral symmetry breaking limit that has been observed in Cs isotopes. The presented analysis shows that the gamma selection rules cannot be attributed only to chiral symmetry breaking. The selection rules relate to structural composition of the chiral rotational bands, i.e. to odd particle configuration and the deformation of the core.

description: Il seguente lavoro di diploma esplora l’efficacia della pratica del consiglio di cooperazione nell'ambito scolastico, concentrandosi sull'ottimizzazione del clima di classe e sulla gestione dei conflitti. L'obiettivo è stato quello di promuovere relazioni positive e ridurre i litigi attraverso l'implementazione dei principi pedagogici di Danielle Jasmin e Célestin Freinet in una classe di quinta elementare. Considerando il contesto classe e attraverso la raccolta di strumenti di diverso tipo, quali i questionari in entrata e uscita, le registrazioni audio, i bigliettini scritti dai bambini e l’osservazione diretta, mi è stato quindi possibile esaminare i dati. Analizzando i risultati dei questionari somministrati alla classe, ho potuto constatare che la pratica proposta ha effettivamente portato benefici nel gruppo; i risultati indicano una diminuzione dei conflitti e un miglioramento nella capacità dei bambini di gestirli autonomamente. La ricerca rivela che l'adozione del consiglio di cooperazione facilita la comunicazione e rafforza le relazioni tra i bambini, facilitando la fiducia reciproca e garantendo che ciascun partecipante si senta coinvolto. Questo studio evidenzia il ruolo positivo della pratica dell’ora di classe nell'ambito educativo, promuovendo un ambiente scolastico più inclusivo e armonioso. Relatore: Reto Torti.
SUSY SU(5) with singlet plus adjoint matter and A4 family symmetry

description: We propose a supersymmetric (SUSY) SU(5) Grand Unified Theory (GUT) including a single right-handed neutrino singlet and an adjoint matter representation below the GUT scale and extend this model to include an A4 family symmetry and a gauged anomaly-free Abelian group. In our approach hierarchical neutrino masses result from a combined type I and type III seesaw mechanism, and the A4 symmetry leads to tri-bimaximal mixing which arises indirectly. The mixing between the single right-handed neutrino and the matter in the adjoint is forbidden by excluding an adjoint Higgs, leading to a diagonal heavy Majorana sector as required by constrained sequential dominance. The model also reproduces a realistic description of quark and charged lepton masses and quark mixings, including the Georgi-Jarlskog relations and the leptonic mixing sum rules s=r*cos(delta) and a=-r^2/4 with r=theta_C/3.

description: We study the Kondo effect in a model system of a quantum dot embedded in an Aharanov-Bohm ring connected to two leads. By transforming to the scattering basis of the direct inter-lead tunneling, we are able to describe precisely how the Kondo screening of the dot spin occurs. We calculate the Kondo temperature and zero-temperature conductance and find that both are influenced by the Aharanov-Bohm ring as well as the electron density in the leads. We also calculate the form of an additional potential scattering term that arises at low energies due to the breaking of particle-hole symmetry. Many of our results are supported by numerical analysis using the numerical renormalization group.

Comparing Likert-type and forced-choice formats for assessing preference : a validation study on the College Major Preference Assessment (CMPA)
Creators: name: Wu, Sirui
Publisher: name: University of British Columbia
Year: 2021

description: This study validated the College Major Preference Assessment (CMPA) by evaluating its effectiveness of using a combination of Likert-type rating scale and forced-choice formats. Following the argument-based approach to validation by Kane (1992), I articulated the interpretation use argument for CMPA and its corresponding warrants and assumptions. The argument was evaluated by the three research questions based on datasets for Education and Psychology: 1) Did the respondents display response set due to Likert-type format of self-assessment? 2) Can the Likert rounds effectively screen out individuals’ “not preferred” majors? 3) Can the forced-choice rounds effectively identify individuals’ favorite major? A two-dimensional latent trait model was tested using structural equation modeling. The results, by and large, confirmed my hypotheses. Both Likert and forced-choice assessments had a very high level of discrimination power for assessing the major trait Favorite (individuals’ inclination towards a major being their favorite). The Likert rounds were relatively less difficult than the forced-choice rounds. The Likert rounds were more reliable for individuals with a relatively lower level of Favorite, and the forced-choice rounds were more reliable for a relatively higher level of Favorite. Moreover, respondents exhibited a response set, shown by the secondary latent trait, which reflected individuals’ perception about the majors when answering Likert-type items. Nonetheless, the assessment of Favorite was not contaminated by perception. All the findings matched the assumptions and warrants for the argument, showing that CMPA worked in the way it was designed for achieving a high level of effectiveness.

description: La Rocca: nata alla fine del medioevo costruzione che precede la fortezza, massiccia grazie a muri perimetrali molto solidi con lo scopo di difendersi dall’artiglieria nemica. Il nuovo nucleo per artisti vuole essere questo, un edificio introverso con una sua vita, con spazi pubblici e spazi privati ben distinti. La Rocca per artisti è delineata da un muro massiccio in pietra artificiale che percorre il perimetro dell’edificazione, dando gradi di privacy differenti; all’interno di esso, gli edifici veri e propri. Edifici leggeri, quasi delicati, che manifestano una leggerezza grazie ad una struttura esile sporgente dalla muraglia, che viene dichiarata dalle aperture in facciata. Un muro che va a proteggere queste strutture così leggere da sembrare un facile bersaglio dalle incursioni esterne, ottenendo una sensazione di serenità e tranquillità al suo interno. Un muro, unico elemento che va a rifarsi alla tradizione delle case massicce del luogo, in quanto tutto il resto dell’edificazione si discosta completamente, sia come sistema strutturale, sia come aperture, sia come forma. Un muro che permette di aggiornare le costruzioni al suo interno poiché sostituibili per seguire il passare del tempo, il modo di vivere. Un muro che nasce dal terreno, si erge insediandosi nella natura. Un muro, che diventa progetto.

description: The giant piezoresistance (PZR) previously reported in silicon nanowires is experimentally investigated in a large number of surface depleted silicon nano- and micro-structures. The resistance is shown to vary strongly with time due to electron and hole trapping at the sample surfaces. Importantly, this time varying resistance manifests itself as an apparent giant PZR identical to that reported elsewhere. By modulating the applied stress in time, the true PZR of the structures is found to be comparable with that of bulk silicon.
