description: In the presence of a scattering potential, electron transport in a quantum wire is known to be dramatically modified by backward scattering and unaffected by forward scattering processes. We show that the scenario is quite different in Quantum Spin Hall effect edge states coupled at a constriction. The helical nature of these states leads to the appearance of a forward scattering spin channel that is absent in other Luttinger liquid realizations. Suitably applied ac gate voltages can thus operate on the spin of electrons tunneling across the constriction, and induce in the dc tunneling current a cusp pattern that represents the signature of the edge state electronic interaction.

description: Kadarka (Vitis vinifera L.) is a red grape variety considered native for the countries on the lower reaches of the Danube River (east of Europe). However, there is very limited knowledge about the evolution of the wines produced from this variety during aging in contact with oak wood. Thus, the aim of this work was to investigate under laboratory conditions the changes in phenolic, volatile, and sensory profile of a Kadarka wine during 180 days in contact with 4 different oak chip species: Q. petraea (French and Hungarian origin), Q. alba, Q. pyrenaica and Q. pubescens. In addition, there is a scarce knowledge about the use of Q. pubescens species in enology. So, another objective was to assess its impact on wine composition. Independently of the oak chip species used, the results obtained demonstrated a decrease of anthocyanin content and an increase of gallic, caffeic and p-coumaric acids during 180 aging days for all wines with oak chips contact. Significantly higher amounts of vanillin in wines aged in contact with Q. petraea from France and Q. alba chips was detected, while wine aged in contact with Q. pubescens chips showed significantly higher amounts of furan derivatives, trans-β-methyl-γ-octalactone and eugenol. From a sensorial point of view, a tendency for higher scores for overall appreciation was obtained for wines aged in contact with Q. petraea chips. The outcomes of this work improved the knowledge of the Kardaka wine characteristics and their evolution in contact with different oak chips and also expanded the knowledge about the use of Q. pubescens in enology.

description: A 50-year-old female was found on exam to have a 2 x 3 cm thin erythematous plaque on her left, proximal upper arm. Biopsy confirmed superficial BCC. Treatment options were reviewed, and the patient elected to proceed with topical 5-FU therapy. Few days later, the patient informed their provider that her dog had ingested a full tube of her 5-FU cream and died. Topical Medications have severe toxic effects on household pets on ingestion. However, a preliminary literature search demonstrated limited articles on topical toxicity in pets in the dermatology space. Therefore, we seek to review topical medications linked to toxicity in household pets. This review will aid in creating a comprehensive guide to inform clinical dermatologists and patients alike of the adverse effects of topically prescribed medications on their pets. A scoping review was selected as the majority of information on topical medication toxicity are case reports. The objective of this review is to examine the prevalence, severity and quality of evidence on pet toxicity related to topical medications prescribed by dermatologists. Our goal is to provide an overview of the scope of existing evidence for provider education and also identify gaps in knowledge for future research.
Investigation of Initial Water Mobility and its Effects on SAGD Performance in Oil Sands

description: Steam-assisted gravity drainage (SAGD) has become a primary commercial in-situ thermal recovery method for oil sands in Alberta. Evidence of initial water mobility during the SAGD process has been observed by many previous field studies. However, no its effective determination method and little research about its effects on SAGD performance have been reported. In this thesis, a novel method is proposed to effectively determine the mobility of initial water existing as the continuous wetting phase in oil sands. More specifically, wax is used for the first time to simulate the immobile oil phase. Laboratory experiments are conducted to determine the initial water mobility with a stationary oil phase. To obtain a general correlation of initial water saturation and its mobility, a triangular tube bundle model is constructed to simulate the measured experimental data. A correlation of the initial water mobility is developed by matching the experimental results with the constructed triangular tube bundle model. To conduct a lab-scale study of initial water mobility, a new two-dimensional physical model with a water flowing boundary is proposed for the first time. The greatest novelty of the 2D model is that the capillary pressure generated from the very fine sands with very strong water wettability, can prevent the oil from flowing into the fine sands zone, but can allow the water flow into the fine sands zone. It is proved by the experiments for the first time that the mobile initial water can promote the vertical and lateral growth of the steam chamber. To investigate effects of initial water mobility on SAGD performance at the field-scale, an elaborated numerical simulation study, with the properties of a typical Athabasca oil sands, is conducted. Initial water mobility is firstly classified into two categories (low and high) based on their steam chamber shapes. The simulation results show that, for a single well pair, low initial water mobility can benefit the steam chamber growth, but high initial water mobility has a negative impact. For the adjacent steam chambers in the same pad, low initial water mobility case with the same injection pressure has the highest NPV.
The Effects of a Hurricane and Fire on Feeding Ecology, Activity Budget, and Social Patterns of Spider Monkeys (Ateles geoffroyi) in Central Belize.

description: Studying the effects of hurricanes on primate populations provides valuable insight into species adaptability and their resiliency to major climatic events. On October 25, 2010 Hurricane Richard hit a spider monkey research site in Belize and was followed by a extensive forest fire 6 months later. Utilizing this rare opportunity and 44 months of data, this study examined activity, diet, and grouping patterns in a group of spider monkeys in multiple time period comparisons. The monkeys showed behavioural, dietary, and grouping flexibility in the aftermath of the storm and fire. Although spider monkeys are generally considered to be ripe fruit specialists, they showed increased folivory after the hurricane. In the shorter term, the monkeys travelled less and spent more time foraging, however that trend did not hold. Subgrouping patterns were not consistent across all time periods examined; however in some comparisons, daily subgroups were more spatially cohesive with fewer changes in membership after the disturbances. Aggression rates significantly decreased after the hurricane, presumably due to an increase in the consumption of evenly distributed, non-defensible leaves. Dietary, behavioural, and grouping flexibility are critical to mitigating the after-effects of major habitat disturbances. However, the coping mechanisms vary when examining different time periods and negative consequences may not present themselves in shorter-term studies.

Dwarf spheroidal satellites of the Milky Way from dark matter free tidal dwarf galaxy progenitors: maps of orbits

description: The long term time evolution of tidal dwarf satellite galaxies with two different initial densities orbiting a host galaxy that resembles the Milky Way has been studied using a large set of Newtonian N-Body simulations. From the simulations two maps of the orbital conditions that lead to quasi-equilibrium objects were constructed. It has been found that several orbits of the satellites allow for the existence, for about 1 Gyr or more, of out-of-equilibrium bodies with high apparent mass-to-light ratios. Within this framework the satellites in the quasi-stable phase reproduce the observed satellite properties for about 16% of the orbit for high density progenitors, and for about 66% for progenitors with lower densities An additional simulation for a single satellite with initial mass of 10^7 Msun and Plummer radius of 0.15 kpc leads to remnants in the quasi- equilibrium phase that simultaneously reproduce remarkably well the observational quantities of the UFDGs of the Milky Way. This satellite in the quasi-stable phase reproduces the observed satellite properties for about 42% of the orbit. The results suggest that a fraction of the observed satellites could plausibly be galaxies without dark matter that have true M/L ratios much lower than those measured. The inflated M/L ratios arise because they are observed at the right time, along the right orbit and during the quasi-equilibrium phase of their evolution. This is a viable explanation for the high M/L ratios observed in all satellites as long as the satellites are preferentially on certain orbits and are observed at certain times. This could arise within the TDG scenario if all satellites are created at the same time along a few specific orbits that are particularly susceptible to the quasi-equilibrium phase.

Cadherin-linked molecular mechanisms governing the terminal differentiation of human trophoblastic cells in vitro

Publisher: name: University of British Columbia
Year: 2010

description: Background: The formation of the multinucleated syncytial trophoblast of the human placenta is a critical step in pregnancy, which is prone to failure. In these studies, I have examined the role of TWIST, a transcription factor identified as a key repressor of E-cad expression in normal and cancer cells of diverse origins, in the differentiation of human trophoblastic cells in vitro. The invasion of extravillous cytotrophoblasts (EVTs) into the underlying maternal tissues and vasculature is a key step in human placentation. The molecular mechanisms underlying the development of the invasive phenotype of EVTs include many of those first identified as having a role in cancer cell metastasis. In view of these observations, I have examined the expression, regulation, and function of Twist, Runx2 and N-cad in human trophoblastic cells in vitro. Materials and Methods: Gain or loss-of-function studies were then performed to determine the role of Twist in terminal differentiation and fusion in these cells. The presence of multinucleated syncytium was confirmed by indirect immunofluorescence. Concentration- and time-dependent studies were performed to determine whether interleukin (IL)-1β and transforming growth factor (TGF)-β1 regulate Twist and Runx2 mRNA and protein levels in EVTs. Next, a siRNA strategy was employed to determine the role of Twist, Runx2 and N-cad in HTR-8/SVneo EVT cells. Results: Exogenous expression of Twist resulted in a continuous and progressive decrease in E-cad expression and the subsequent formation of syncytium in BeWo cells maintained under normal culture conditions. In contrast, siRNA specific for Twist inhibited the cAMP-mediated differentiation of these cells over time in culture. The cytokines, IL-1β and TGF-β1, respectively induced the differential up- and down-regulation of Twist and Runx2 expression in primary cultures of EVTs in both a concentration and time-dependent manner. Use of a siRNA strategy demonstrated that a reduction in Twist, Runx2 or N-cad in HTR-8/SVneo cells concomitantly decreased the invasiveness of these cells. Conclusions: Collectively, my findings demonstrate that TWIST is an upstream regulator of the E-CAD-mediated terminal differentiation and fusion of human trophoblastic cells in vitro. TWIST, RUNX2 and N-CAD are key molecules underlying the invasive capacity of EVTs.

description: Explosive energy release is a common phenomenon occurring in magnetized plasma systems ranging from laboratories, Earth's magnetosphere, the solar corona and astrophysical environments. Its physical explanation is usually attributed to magnetic reconnection in a thin current sheet. Here we report the important role of magnetic flux rope structure, a volumetric current channel, in producing explosive events. The flux rope is observed as a hot channel prior to and during a solar eruption from the Atmospheric Imaging Assembly (AIA) telescope on board the Solar Dynamic Observatory (SDO). It initially appears as a twisted and writhed sigmoidal structure with a temperature as high as 10 MK and then transforms toward a semi-circular shape during a slow rise phase, which is followed by fast acceleration and onset of a flare. The observations suggest that the instability of the magnetic flux rope trigger the eruption, thus making a major addition to the traditional magnetic-reconnection paradigm.

description: Spatial structure, optimal behaviour, and social/cultural practices are examined in relation to each other and observed movement and land-use behaviours of precontact peoples in Jasper National Park. Natural and inherent movement characteristics of the landscape are modeled and assessed using space syntax theory so as to gain a greater understanding in the objectives and motivations behind precontact human use of various regions within the Jasper study area. Modeling uses elevation limits to define movement barriers and river valleys to structure travel corridors. Movement potential is examined based on landscape morphology and the visibility characteristics of the landscape. Evidence of movement patterns is quantified by the presence and distribution of known archaeological sites. Movement objectives are postulated by examining resource distribution and availability surrounding known site locations. Evidence suggests that precontact human behaviour centred within highly locally connected, globally integrated, and inherently intelligible regions within the greater movement network. This pattern of movement and land-use suggests the use of a generalized risk reduction strategy by the majority of precontact peoples accessing the Jasper area, focusing the majority of their activities within easily accessible, well connected, and centrally located areas within Jasper National Park. This suggests adept and knowledgeable, yet not highly adapted, outside populations accessing the area. Current archaeological data suggest that the majority of precontact movement and occupation in the Jasper area centred on general resource procurement (e.g. elk and bighorn sheep hunting) and/or trans-mountain travel objectives within these centralized locations, and under this risk reduction framework. Isolated and poorly integrated regions of the Jasper travel network are not completely void of archaeological sites however, thus suggesting a wider and more complete use of the Jasper area, albeit with varying intensity and focus. It is suggested that small isolated unconformities within this greater pattern likely signify specialized and unique movement and land-use behavioural characteristics of sub-regions within the network, such as important procurement areas and/or specialized hunting loci. The identification of these areas has the potential to provide greater insight and understanding into highly specialized and unique adaptations and cultural practices within the Japer area.
WIMPless Dark Matter in Anomaly-Mediated Supersymmetry Breaking with Hidden QED

description: In anomaly-mediated supersymmetry breaking, superpartners in a hidden sector have masses that are proportional to couplings squared, and so naturally freeze out with the desired dark matter relic density for a large range of masses. We present an extremely simple realization of this possibility, with WIMPless dark matter arising from a hidden sector that is supersymmetric QED with N_F flavors. Dark matter is multi-component, composed of hidden leptons and sleptons with masses anywhere from 10 GeV to 10 TeV, and hidden photons provide the thermal bath. The dark matter self-interacts through hidden sector Coulomb scatterings that are potentially observable. In addition, the hidden photon contribution to the number of relativistic degrees of freedom is in the range ΔN_eff ~ 0 - 2, and, if the hidden and visible sectors were initially in thermal contact, the model predicts ΔN_eff ~ 0.2 - 0.4. Data already taken by Planck may provide evidence of such deviations.

title: Reframing intercultural education in edu-business: A decolonising approach
Creators: name: Lee, Judith L.
Publisher: name: University of Glasgow
Year: 2025

description: The ever-evolving global context has brought an increased focus on nonformal learning organisations such as edu-business which provides learning services as a ‘for-profit’ enterprise (Ball, 2012). However, edu-business is shaped by the neoliberal environment in which it is embedded. Its underlying economic drivers comprise the core challenges for learning developers in this sector. Moreover, there is a remarkable absence of research specific to edu-business which has raised questions on its capability in a globally diverse learning context. This study aimed to close that research gap slightly by concentrating on the specific learning area of intercultural education and the possibilities of a decolonising approach to curriculum and pedagogy. Specifically, the focus was on how knowledge is validated, how it is disseminated and by whom in edu-business. The overall study aim was not to provide a decolonising solution or set of guidelines for edu-business but to initiate a dialogue on decolonising intercultural education for edu-business. This study interrogated the pedagogical approaches to intercultural education for edu-businesses in Europe by exploring issues related to ‘quality of content’ (Krishna, 2009) for curriculum and pedagogy.

Using a qualitative research design, the data was collected from semi-structured interviews with learning developers in European-based edu-businesses. A framework analysis drew from concepts delineated by Shahjahan, Estera, Surla and Edwards’ (2022) decolonising curriculum and pedagogy (DCP) framework for higher education which provided a relevant comparison for exploring a decolonising approach to intercultural curriculum and pedagogy in edu-business. The research findings highlighted issues related to the contextual challenges, interrelated interpretations and the actualisation of decolonising pedagogy which have implications for how learning developers recognise conditions and relations of power in which intercultural learning is embedded. It requires their capacity to acknowledge their complicity, subjectivity and pedagogical agency in the propagation of dominant Eurocentric approaches which sanction power relations and have an impact on the quality of intercultural programmes in edu-business. The learning developers’ unique positionality has the potential to transform intercultural knowledge production into a more critically relevant and humancentric pedagogical practice as part of the greater decolonising project.

description: The detection of binary black hole coalescences by LIGO/Virgo has aroused the interest in primordial black holes (PBHs), because they could be both the progenitors of these black holes and a compelling candidate of dark matter (DM). PBHs are formed soon after the enhanced scalar perturbations re-enter horizon during radiation dominated era, which would inevitably induce gravitational waves as well. Searching for such scalar induced gravitational waves (SIGWs) provides an elegant way to probe PBHs. We perform the first direct search for the signals of SIGWs accompanying the formation of PBHs in North American Nanohertz Observatory for Gravitational waves (NANOGrav) 11-year data set. No statistically significant detection has been made, and hence we place a stringent upper limit on the abundance of PBHs at $95\%$ confidence level. In particular, less than one part in a million of the total DM mass could come from PBHs in the mass range of $[2 \times 10^{-3}, 7\times 10^{-1}] \Msun$.

description: This thesis examines the rhetorical strategies used in the speeches of Mitt and Ann Romney, and Barack and Michelle Obama at the 2012 Republican and Democratic National Conventions. It does so in order to gain insight into the communications strategies of each of the major political parties, and project about the future directions of The Republican Party. The method of this study involves a comparative rhetorical analysis of the four speeches mentioned, and examines the rhetorical strategies used in each of these speeches. Similarities and differences were observed between the ways that each speaker appealed to Americans of lower socioeconomic status, female voters, and Christian voters. Additionally, news media and other online sources were used to contextualize each speech, and gauge audience responses to them. This study hypothesizes that in order to continue to contend with the Democratic Party, the Republican Party may need to alter its rhetoric to be more appealing to diverse groups of voters.

description: Due to the inherent ability of porphyrins to harvest light, researchers have been striving to expand upon their optical and electronic properties. This thesis investigates the design and improvement of the ability of porphyrins to collect light for applications as donor materials to organic electronics. Derivatives of 21,23-dithiaporphyrins were investigated for their optical and electrochemical properties, in addition to studying the possibility of long-range ordering through the formation of liquid crystalline mesogens. It was found that these dithiaporphyrin derivatives are likely soft-crystalline and through their ability to long-range order, were able to increase their conductivity in a thin-film. The improvements of optical, electrochemical and self-assembling ability of these 21,23-dithiaporphyrins compared to their tetra pyrrolic analogues, prompted the inclusion of these molecules, as a light harvester, into a dye-sensitized solar cell. While the cell was unsuccessful, new dithiaporphyrin chemistry was explored and the optical and electrochemical properties of dithiaporphyrins were studied. To further improve the ability of dithiaporphyrins to harvest light, synthetic changes were made to incorporate planar ethynyl meso-spacers, as well as fuse polycyclic aromatic hydrocarbons to the back bone of the macrocyclic, porphyrin core. Through the gradual improvement in the design of these dithiaporphyrins, it was found that the absorption profile of these compounds broadened and red-shifted to lower wavelengths, compared to tetra pyrrolic analogues. Additionally, it was found that these compounds could oxidize more readily, while still maintaining electronic energy levels, compatible with acceptor materials, for organic photovoltaic applications. Acenaphthene fused dithiaporphyrins exhibited the most encouraging light harvesting properties compared to all the derivatives within this work. These electron rich, highly delocalized dithiaporphyrins, displayed red-shifted absorbance profiles which were capable of harvesting low energy photons beyond 1000 nm. Additionally, these derivatives were able to oxidize at very low potentials, while maintaining stability in air. While these molecules did not display long-range ordering ability, they did show promising, non-covalent, interactions with the common fullerene acceptor material, C60.

description: Multiple-trait analyses have been shown to improve the detection of quantitative trait loci (QTLs) with multiple effects. Here we applied a multiple-trait approach on obesity- and growth-related traits that were surveyed in 275 F2 mice generated from an intercross between the high body weight selected line NMRI8 and DBA/2 as lean control. The parental lines differed 2·5-fold in body weight at the age of 6 weeks. Within the F2 population, the correlations between body weight and weights of abdominal fat weight, muscle, liver and kidney at the age of 6 weeks were about 0·8. A least squares multiple-trait QTL analysis was performed on these data to understand more precisely the cause of the genetic correlation between body weight, body composition traits and weights of inner organs. Regions on Chr 1, 2, 7 and 14 for body weights at different early ages and regions on Chr 1, 2, 4, 7, 14, 17 and 19 for organ weights at 6 weeks were found to have significant multiple effects at the genome-wide level.

description: The evolution of mesoscopic structure for cement-water mixtures turning into colloidal gels remains far from being understood. Recent neutron scattering investigations (Phys. Rev. Lett. 93, 255704 (2004); Phys. Rev. B. 72, 224208 (2005); Phys. Rev. B. 82, 064203 (2010)),, reveal the role of hydrogen bond in temporal evolution of the mesoscopic structure during hydration of cement which is the most consumed synthetic material. The present neutron scattering investigation on hydration of cement with a mixture of light and heavy water points to incomprehensibility of the temporal evolution of the mesoscopic structure in terms of earlier observations on hydration with pure light or heavy water. Unlike in the case of hydration with light water, disagreement has been observed with the hypothesis of dynamical scaling for hydration of cement with a mixture of the two types of water. The dynamics of evolution of the mesoscopic structure has been observed to be nonlinear in regard to the composition of hydration medium.

description: In this thesis, we apply Stacked Denoising Autoencoder (SDAE), a major type of deep learning networks, to spam detection. We comprehensively compare its performances with other prevalent deep learning techniques, Deep Belief Network (DBN) and Dense Multi Layer Perceptron (Dense- MLP), which can be further applied to spam filtering. We further compared the performance of these deep learning technologies against state-of-the-art, Support Vector Machines (SVM). Experiments were conducted on five benchmark corpora, namely PU1, PU2, PU3, PUA, and Enron- Spam. Accuracy, Precision, Recall and F1 measure are selected as the main criteria in analysing and discussing the results. Experimental results verify the efficacy of deep learning approaches with application in spam filtering in the real world. This project is part of the larger research in deep learning being conducted by the Wedge Networks- a leading technology vendor in security services. Wedge Networks is actively doing great work in the different realms of securing data on the internet and the cloud- including spam classification, web-page classification, and virus detection among others. This study delves deeper into applying deep learning to spam classification in particular and checks its credibility against the state-of-the-art algorithm- SVM.
Group actions on finite homotopy spheres

Publisher: name: University of British Columbia

description: Recently, Grodal and Smith [7}have developed a finite algebraic model to study hG-spaces where G is a finite group. The procedure associates to each G-space X with finite F_p homology a perfect chain complex of functors over the orbit category. When X has the homotopy type of a sphere, this construction is particularly well behaved. The reverse construction, building an hG-space from the algebraic model, generally produces an infinite dimensional space. In this thesis, we construct a finiteness obstruction for hG-spheres working one prime at a time. We then begin the development of a global finiteness obstruction. When G is the metacyclic group of order pq, we are able to go further and express the global finiteness obstruction in terms of dimension functions. In addition, we relate the work of tom Dieck and Petrie [19] concerning homotopy representations to the newer model of Grodal and Smith, and compute the rank of V_w(G). We conclude with some new examples of finite Σ₃-spheres.

description: Kernel matrices are of central importance to many applied fields. In this manuscript, we focus on spectral properties of kernel matrices in the so-called ``flat limit'', which occurs when points are close together relative to the scale of the kernel. We establish asymptotic expressions for the determinants of the kernel matrices, which we then leverage to obtain asymptotic expressions for the main terms of the eigenvalues. Analyticity of the eigenprojectors yields expressions for limiting eigenvectors, which are strongly tied to discrete orthogonal polynomials. Both smooth and finitely smooth kernels are covered, with stronger results available in the finite smoothness case.

title: Effects of Tooth Whitening Use on Oral Health Interests and Values in Adults

description: The primary purpose of this study was to determine if tooth whitening product use influences oral health interests and values in an adult population. A two-group, randomized, pre-test, multiple post-test design was used for studying 60 adults between the ages of 18 and 60. Persons who use tobacco products, have composite/tooth-colored anterior restorations, less than eight anterior teeth, pregnant or lactating women, or those who have previously used a whitening product other than toothpaste were excluded from the study. At baseline, a researcher-designed Oral Health Questionnaire was administered to consenting adults to determine the level of oral health interests and values. A three-week, twice daily whitening strip regimen was administered to 30 randomized participants; the remaining 30 participants received no whitening treatment for the same three-week period. All individuals were instructed to use the same toothpaste, toothbrush and floss, and brush twice daily for two minutes at each brushing session. The questionnaire was re-administered at two and four-weeks after baseline to determine change in individuals' oral health interests and values. Useable data were collected from 50 adults, 22 adults who received whitening treatment and 28 adults who received no treatment. The Wald-Chi Squared test at p=.05 was used to determine relationships between tooth color and various oral health interests and values. Results showed that both the whitening and non-whitening groups experienced a significant increase in their oral health interests from baseline to four weeks. Those in the experimental group who found their teeth lighter in shade had more interest in their overall oral health than those whose tooth shade did not change. An increase in participants' oral health interest and value occurred; however, both the experimental and control groups' interests and values increased at the same rate. Only the experimental group had a significant change in their oral health values after improvement in their tooth color. As tooth color lightened, oral health values increased. Results also revealed a link between whiter teeth and an increase in the value and interest one might place on their oral health. More research is needed before vital tooth whitening can be viewed as a therapeutic procedure.
