description: Context. We observe a solar jet at north polar coronal hole (NPCH) using SDO AIA 304 °A image data on 3 August 2010. The jet rises obliquely above the solar limb and then retraces its propagation path to fall back. Aims. We numerically model this observed solar jet by implementing a realistic (VAL-C) model of solar temperature. Methods. We solve two-dimensional ideal magnetohydrodynamic equations numerically to simulate the observed solar jet. We consider a localized velocity pulse that is essentially parallel to the background magnetic field lines and initially launched at the top of the solar photosphere. The pulse steepens into a shock at higher altitudes, which triggers plasma perturbations that exhibit the observed features of the jet. The typical direction of the pulse also clearly exhibits the leading front of the moving jet. Results. Our numerical simulations reveal that a large amplitude initial velocity pulse launched at the top of the solar photosphere produces in general the observed properties of the jet, e.g., upward and backward average velocities, height, width, life-time, and ballistic nature. Conclusions. The close matching between the jet observations and numerical simulations provides first strong evidence for the formation of this jet by a single velocity pulse. The strong velocity pulse is most likely generated by the low- atmospheric reconnection in the polar region which results in triggering of the jet. The downflowing material of the jet most likely vanishes in the next upcoming velocity pulses from lower solar atmosphere, and therefore distinctly launched a single jet upward in the solar atmosphere is observed.

description: We present the mode identification of frequencies found in spectroscopic observations of the Gamma Doradus star HD135825. Four frequencies were successfully identified: 1.3150 +/- 0.0003 1/d; 0.2902 +/- 0.0004 1/d; 1.4045 +/- 0.0005 1/d; and 1.8829 +/- 0.0005 1/d. These correspond to (l, m) modes of (1,1), (2,-2), (4,0) and (1,1) respectively. Additional frequencies were found but they were below the signal-to-noise limit of the Fourier spectrum and not suitable for mode identification. The rotational axis inclination and vsini of the star were determined to be 87 degrees (nearly edge-on) and 39.7 km/s (moderate for Gamma Doradus stars) respectively. A simultaneous fit of these four modes to the line profile variations in the data gives a reduced chi square of 12.7. We confirm, based on the frequencies found, that HD135825 is a bona fide Gamma Doradus star.

description: We present BVR observations of DK CVn from 2007 and 2008. We analysed the BVR light curves of the system and obtained the system's parameters. Using the `q-search' method, we measured the mass ratio of the system (q) as 0.55. Taking the temperature of the primary component as 4040K, the temperature of the secondary was found to be 3123K. Several flares were detected, and the distributions of flare equivalent duration versus flare total duration were modelled using the One-Phase Exponential Association Function for these flares. The parameters of the model demonstrated that the flares are the same as those detected from UV Ceti stars. We also demonstrate that the variation at out-of-eclipse must be caused by some cool spot(s) on one of the components. The star is found to show two active longitudes in which the spots are mainly formed. Consequently, this study reveals that DK CVn should be a chromospherically active binary star.

description: Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present.

description: We test two different methods of using near-infrared extinction to estimate distances to dark clouds in the first quadrant of the Galaxy using large near infrared (2MASS and UKIDSS) surveys. VLBI parallax measurements of masers around massive young stars provide the most direct and bias-free measurement of the distance to these dark clouds. We compare the extinction distance estimates to these maser parallax distances. We also compare these distances to kinematic distances, including recent re-calibrations of the Galactic rotation curve. The extinction distance methods agree with the maser parallax distances (within the errors) between 66% and 100% of the time (depending on method and input survey) and between 85% and 100% of the time outside of the crowded Galactic center. Although the sample size is small, extinction distance methods reproduce maser parallax distances better than kinematic distances; furthermore, extinction distance methods do not suffer from the kinematic distance ambiguity. This validation gives us confidence that these extinction methods may be extended to additional dark clouds where maser parallaxes are not available.

description: Adaptive learning support provided by kindergarten teachers before and after (macro-adaptive learning support) as well as during mathematical learning activities (micro-adaptive learning support) is a cross-cutting concept of teaching quality. Effective adaptive learning support enhances children's learning. However, providing it is challenging and teachers need professional development (PD) to improve the quality of their support. This study investigates the mediating role of teaching quality between PD programs for kindergarten teachers and the development of children's mathematical competency. 122 kindergarten teachers and their 825 pupils participated in the study. The teachers were randomly assigned to three groups. Two groups attended PD sessions designed to foster either macro- or micro-adaptive learning support. The third was the materials-only control group. The data was analyzed using a self-developed rating instrument focusing on generic and domain-specific elements of teaching quality related to macro- and micro-adaptive learning support. The multilevel latent change model analysis revealed that the PD programs had positive and significant effects on the teaching quality of kindergarten teachers. A significant positive relationship was also found between micro-adaptive learning support and changes in children's mathematical competency. However, an indirect effect of teaching quality could not be detected, and the PD programs did not have a total effect on children's mathematical competency. The study reinforces the importance of PD that specifically targets macro- and micro-adaptive learning support for kindergarten teachers. The mediation between PD and mathematical competency development requires further investigation.
Evaluating source water protection strategies : a soft computing approach
Creators: name: Islam, Nilufar
Publisher: name: University of British Columbia

description: Source water protection is an important step in the implementation of a multi-barrier approach that ensures delivery of safe drinking water cost effectively. However, implementing source water protection strategies can be a challenging task due to technical and administrative issues. Currently many decision support tools are available that mainly use complex mathematical formulations. These tools require large data sets to conduct the analysis, which make their use very limited. A simple soft-computing model is proposed in this research that can estimate and predict a reduction in the pollutant loads based on selected source water protection strategies that include storm water management ponds, vegetated filter strips, and pollution control by agricultural practice. The proposed model uses an export coefficient approach and number of animals to calculate the pollutant loads generated from different land uses (e.g., agricultural lands, forests, roads, livestock, and pasture). A surrogate measure, water quality index, is used for the water assessment after the pollutant loads are discharged into the source water. To demonstrate the proof of concept of the proposed model, a Page Creek Case Study in Clayburn Watershed (British Columbia, Canada) was conducted. The results show that rapid urban development and improperly managed agricultural area have the most adverse effects on the source water quality. On the other hand, forests were found to be the best land use around the source water that ensures acceptable drinking water quality with a minimal requirement for treatment. The proposed model can help decision-makers at different levels of government (Federal/ Provincial/ Municipal) to make informed decisions related to land use, resource allocation and capital investment
Multilayer graphene nanoribbon under vertical electric field

description: We study the effect of vertical electric-field (E-field) on the electronic properties of the multilayer armchair graphene nanoribbon (aGNR). Under E-field, the band structure of a bilayer aGNR undergoes interesting transformations such as change in the electron velocity, sign of the electron effective mass, band gap, the position of the band gap in the momentum space. Depending on the width of the aGNR and the applied E-field, the band gap of the aGNR may either be increased or decreased. When the applied E-field is above a critical value, the band gap of the bilayer aGNR is identical to that of the bilayer graphene, independent of the width. We also show that, for semiconducting multilayer aGNR with more than two layers, the band gap decreases with increasing E-field, resulting in a semiconductor-to-metallic transition. This can be utilized to enhance the performance of a graphene based transistor devices.

description: We report the laser cooling and trapping of neutral potassium on an open transition. Fermionic 40K is captured using a magneto-optical trap (MOT) on the closed 4S-4P transition at 767 nm and then transferred, with unit efficiency, to a MOT on the open 4S-5P transition at 405 nm. Because the 5P state has a smaller line width than the 4P state, the Doppler limit is reduced. We observe temperatures as low as 63(6) microkelvin, the coldest potassium MOT reported to date. The density of trapped atoms also increases, due to reduced temperature and reduced expulsive light forces. We measure a two-body loss coefficient of 2 x 10^-10 cm^3/s, and estimate an upper bound of 8x10^-18 cm^2 for the ionization cross section of the 5P state at 405 nm. The combined temperature and density improvement in the 405 nm MOT is a twenty-fold increase in phase space density over our 767 nm MOT, showing enhanced pre-cooling for quantum gas experiments. A qualitatively similar enhancement is observed in a 405 nm MOT of bosonic 41K.

description: Taking into account results obtained from light-curve analysis and out-of-eclipse analyses, we discuss the nature of GSC 02038-00293 and also its magnetic activity behaviour. We obtained light curves of the system during observing seasons 2007, 2008 and 2011. We obtained its secondary minimum clearly in I-band observations in 2008 for the first time. Analysing this light curve, we found the physical parameters of the components. The light-curve analysis indicates that the possible mass ratio of the system is 0.35. We obtained the remaining V-band light curves, extracting the eclipses. We modelled these remaining curves using the spotmodel program and found possible spot configurations of the magnetically active component for each observing season. The models demonstrated that there are two active longitudes for the active component. The models reveal that both active longitudes migrate in the direction of decreasing longitude. We also examined the light curves in out-of-eclipse phases with respect to minimum and maximum brightness, amplitude, etc. The amplitude of the curves during out-of-eclipse phases varies in a sinusoidal way with a period of ~8.9yr the mean brightness of the system is dramatically decreasing. The phases of the deeper minimum during out-of-eclipse periods exhibit a migration toward decreasing phase.

description: Early childhood language experiences influence how a child’s mind and brain process language and acquire literacy. For children growing up bilingual, their two languages interact in their minds, and these cross-linguistic influences can lead to unique neurocognitive mechanisms for language and reading compared to monolinguals. In this dissertation, I asked: how does early bilingualism impact children’s cognitive and neural organization for learning to read? To address this question, this dissertation includes three inter-related studies of behavioral and functional Near-Infrared Spectroscopy (fNIRS) neuroimaging assessments with young Chinese-English bilingual, Spanish-English bilingual, and English monolingual children (N = 283, ages 5-11). Children completed language and literacy tasks in each of their respective languages while their parents completed questionnaires on children’s language use. Studies 1 and 2 revealed that bilingual children processed English words in a way that reflected their proficiency with the characteristics of their heritage language – in particular, Chinese bilinguals relied more on meaning-based skills, whereas Spanish bilinguals on sound-based skills, to read English words (Study 1); and in both groups, higher heritage language proficiency is associated with stronger activations in the left temporal brain region when processing English words (Study 2). Study 3 further revealed that bilinguals with stronger dual language proficiency formed more widespread neural connections within the neural network for language processing. Taken together, the findings suggest that heritage language influences children’s literacy development and emerging neural organization for learning to read and these bilingual influences reflect children’s experiences and proficiency with both of their languages. These findings thus inform theories of bilingualism and literacy instruction for children from diverse socio-linguistic backgrounds.

description: Using a simple lumped-circuit model, we numerically study the dependence of the voltage gain and noise on the amplifier's parameters. Linear, quasi-linear, and nonlinear regimes are studied. We have shown that the voltage gain of the amplifier cannot exceed a characteristic critical value, which decreases with the increase of the input power. We have also shown that the spectrum of the voltage gain depends significantly on the level of the Johnson noise generated by the SQUID resistors.

description: Quantum simulators are controllable systems that can be used to simulate other quantum systems. Here we focus on the dynamics of a chain of molecular qubits with interposed antiferromagnetic dimers. We theoretically show that its dynamics can be controlled by means of uniform magnetic pulses and used to mimic the evolution of other quantum systems, including fermionic ones. We propose two proof-of-principle experiments, based on the simulation of the Ising model in transverse field and of the quantum tunneling of the magnetization in a spin-1 system.

description: Breast cancer screening programs using two dimensional (2D) digital mammography (DM), have proven effective in early detection of cancer subsequently reducing breast cancer related deaths. A major drawback of DM arises from large amounts of overlapping breast tissues which may mimic or conceal abnormalities in a 2D image. Advanced breast imaging technologies like digital breast tomosynthesis (DBT) generating 3D information are now being considered as a replacement for DM in screening programs. However, the benefits of DBT based screening for earlier detection of cancer, across the various commercially available detector technologies, are yet to be established. The aim of this thesis is to investigate the influence of x-ray imager technologies and imaging modalities on the early detection of breast cancer using in silico trials. The first part of this thesis focuses on developing computational models that replicate the growth of cancerous lesions and the detector physics of commercially available DM/DBT systems. I propose a growth model for breast lesions based on biological and physiological phenomena accounting for the stiffness of surrounding anatomical structures. Depending on the breast's local anatomical structures, a range of unique lesion morphology was realized. Imaging physics models were developed to simulate direct and indirect x-ray detector technology. Image quality metrics were compared against measured data from three commercially available DM/DBT systems. Finally, these tools combined with the VICTRE 1.0 in silico framework were used to design in silico trials to study whether DBT can facilitate the detection of breast cancer at earlier disease stages and for a range of detector technologies. The in silico studies suggest that while DBT shows clear advantages for detecting masses at earlier stages, its benefits over DM for detecting micro-calcifications depend on the detector technology.

description: The tensor product $(G_1,G_2)$ of a graph $G_1$ and a pointed graph $G_2$ (containing one distinguished edge) is obtained by identifying each edge of $G_1$ with the distinguished edge of a separate copy of $G_2$, and then removing the identified edges. A formula to compute the Tutte polynomial of a tensor product of graphs was originally given by Brylawski. This formula was recently generalized to colored graphs and the generalized Tutte polynomial introduced by Bollobás and Riordan. In this paper we generalize the colored tensor product formula to relative Tutte polynomials of relative graphs, containing zero edges to which the usual deletion-contraction rules do not apply. As we have shown in a recent paper, relative Tutte polynomials may be used to compute the Jones polynomial of a virtual knot.

Magnetic structure of hexagonal YMnO3 and LuMnO3 from a microscopic point of view

description: The aim of this work is to unravel a basic microscopic picture behind complex magnetic properties of hexagonal manganites. For these purposes, we consider two characteristic compounds: YMnO3 and LuMnO3, which form different magnetic structures in the ground state. First, we establish an electronic low-energy model, which describes the behavior of the Mn 3d bands of YMnO3 and LuMnO3, and derive parameters of this model from the first-principles calculations. From the solution of this model, we conclude that, despite strong frustration effects in the hexagonal lattice, the relativistic spin-orbit interactions lift the degeneracy of the magnetic ground state so that the experimentally observed magnetic structures are successfully reproduced by the low-energy model. Then, we analyze this result in terms of interatomic magnetic interactions, which were computed using different approximations (starting from the model Hamiltonian as well as directly from the first-principles electronic structure calculations in the local-spin-density approximation). We argue that the main reason why YMnO3 and LuMnO3 tend to form different magnetic structures is related to the behavior of the single-ion anisotropy, which reflects the directional dependence of the lattice distortion: namely, the expansion and contraction of the Mn-trimers, which take place in YMnO3 and LuMnO3, respectively. On the other hand, the magnetic coupling between the haxagonal planes is controlled by the next-nearest-neighbor interactions, which are less sensitive to the direction of the trimerization. Finally, using the Berry-phase formalism, we evaluate the magnetic-state dependence of the ferroelectric polarization, and discuss potential applications of the latter in magnetoelectric switching phenomena.

Quantifying the road safety benefits of sustainable transportation : transit
Creators: name: Alam, Ahsan
Publisher: name: University of British Columbia
Year: 2010

description: As more and more people require transportation, not only must it be efficient and economically affordable, it must also increase safety and be environmentally friendly. High road traffic collisions have been recognized as a global major public health and safety problem. Present autodominant culture results in more traffic congestion, collisions, and environmental deterioration. So, there is a need to shift people from auto to a more sustainable transportation system that will promote reduced congestion levels, reduced environmental pollutions, improved road safety, and regional economic growth. This research quantified the road safety benefits of sustainable transportation in the form of increased transit services. The objective of the research was: (1) to develop an auto-based transportation planning model of the Regional District of Central Okanagan (RDCO) for year 2006 and 2020; (2) to conduct road safety analysis due to future transit and road network improvements; and, (3) to identify collision prone locations of the region. This research built AM period 4-step transportation planning model of the RDCO for the years 2006 and 2020. It proposed RDCO specific trip generation rate and a new auto mode share model, which can be used for future transportation modeling of the region. This research developed collision prediction models (CPMs) for the RDCO, which can be used to predict future AM period collisions. This research also built RDCO transportation planning model for 2020 having four sub-scenarios: (1) do-nothing; (2) only road improvements; (3) only transit improvements; and, (4) both transit and road improvements. It was found that transit improvements have the potential to significantly reduce urban and rural collisions. This research also suggests that construction of new roads in rural areas might result in collision increases. This is a very important consideration for transportation planners before constructing new roads in rural areas. This research also identified, ranked and analyzed collision prone locations (CPLs)which would help decision makers as they consider where to spend resources, targeting locations with the highest potential for safety improvements. It is believed that the results of this research would contribute significantly in future transportation planning and road safety evaluation of the region.

description: To investigate whether optic nerve ganglion cell amount is dependent on optic disc size, this trial analyzes the correlation between Bruch’s membrane opening area (BMOA) and retinal nerve fiber layer (RNFL) thickness as well as macular ganglion cell layer thickness (mGCLT). Additionally, differences in RNFL and mGCLT regarding various optic disc cohorts are evaluated. This retrospective, monocentric study included 501 healthy eyes of 287 patients from the University Hospital Münster, Germany, who received macular and optic disc optical coherence tomography (OCT) scans. Rank correlation coefficients for clustered data were calculated to investigate the relationship between BMOA and thickness values of respective retinal layers. Furthermore, these values were compared between different optic disc groups based on BMOA. Statistical analysis did not reveal a significant correlation between BMOA and RNFL thickness, nor between BMOA and mGCLT. However, groupwise analysis showed global RNFL to be significantly decreased in small and large discs in comparison to medium discs. This was not observed for global mGCLT. This study extends existing normative data for mGCLT taking optic disc size into account. While the ganglion cell amount represented by the RNFL and mGCLT seemed independent of BMOA, mGCLT was superior to global RNFL in displaying optic nerve integrity in very small and very large optic discs.

times of social distancing

description: There is a growing research interest in the effects of social distancingmeasures introduced to prevent the spread of COVID-19 on social inter-action, interpersonal relationships, and personal wellbeing. In the soccerarena, too, players, referees, managers, and fans are subject to socialdistancing measures when engaging in joint activities in times of thepandemic. This paper examines to what extent agents on the soccerpitch have adapted joint communicative acts such as goal celebrationsand surrounding the referee as part of social distancing measures. It doesso by focusing particularly on interactions between player-player (goalcelebrations) and player-referee (issuing of yellow/red cards) in broad-casted Premier League games pre- and post-lockdown during the 2019/20season by examining and comparing two datasets: games in the lastround before the three-month lockdown break (round 29, 10 games, 7-9 March 2020) and the games in the first round after the restart of season2019/20 with the implemented social distancing rules as prescribed by thePremier League's Season 2019/20Restart Guide (round 30, 10 games, 19-22 June 2020). Based on an exploratory, qualitative multimodal analysis ofa total of 43 goal celebrations and the issuing of 66 yellow cards and onered card in the two datasets, we highlight varying realizations of similarjoint communicative acts, thereby demonstrating how agents on thepitch adapt their interaction to social distancing rules. The results showplayers' occasional hesitation to gather closely with other players tocelebrate a goal and their deviation to more common practices of enga-ging with others during times of COVID-19, for example fist bumps.Adaptation of interaction can also be observed with regard to player-referee interactions following a booking, most notably concerning sur-rounding the referee in contested decisions: While players still movetowards the referee seemingly crowding the referee, there is, in somescenes, a visible restraint by players to ensure enough distancing betweenthe players and the referee.

Predictable Performance and Low Cost for Geo-Distributed Applications

description: Applications that run in the cloud must be geo-distributed to achieve high reliability, minimize delays, and follow data localization laws. However, geo-distributed applications face many challenges in achieving these goals due to a key bottleneck: the wide-area network (WAN). Without enough, cheaply-available WAN bandwidth, applications are forced to degrade the service they provide or shut down altogether. Additionally, the latency between data centers limits how quickly an application can serve user requests. My dissertation makes two contributions to better serve providers of geo-distributed applications. First, I present a new architecture, HEYP, for sharing a private WAN across many tenants. State-of-the-art WANs maximize efficiency by trying make use of every bit of spare capacity on the network. However, in doing so, they risk introducing interference between tenants. In contrast, HEYP offers strong isolation guarantees between tenants, but without sacrificing the efficiency of existing shared WANs. Next, I characterize the impact that latency has on read and write operations when manipulating data that is stored in multiple data centers, and how there exists a three-way tradeoff between optimizing for read latency, write latency, and cost. I study existing approaches and identify inefficiencies that cause them to require significantly higher cost than necessary to meet a set of latency targets. I then describe the design of Pando, a system that I have developed to offer a near-optimal tradeoff between read latency, write latency, and cost. Both Pando and HEYP offer substantially improved tradeoffs between performance and cost that can benefit geo-distributed applications. More generally, however, my work shows that current geo-distributed systems offer tradeoffs that are suboptimal in important ways, and that focusing on the constraints of WANs will be a key part of improving them.
Leptogenesis from a GeV Seesaw without Mass Degeneracy

description: For Leptogenesis based on the type-I seesaw mechanism, we present a systematic calculation of lepton-number violating and purely flavoured asymmetries within nonequilibrium Quantum Field Theory. We show that sterile neutrinos with non-degenerate masses in the GeV range can explain the baryon asymmetry of the Universe via flavoured Leptogenesis. This is possible due to the interplay of thermal and flavour effects. Our approach clarifies the relation between Leptogenesis from the oscillations of sterile neutrinos and the more commonly studied scenarios from decays and inverse decays. We explain why lower mass bounds for non-degenerate sterile neutrinos derived for Leptogenesis from out-of-equilibrium decays do not apply to flavoured Leptogenesis with GeV-scale neutrinos.

Subjects: outdoor education, initial formal schoolteacher training, pre-service teachers, systematic literature review, skills, pedagogical strategies

description: In the field of school-based outdoor education, researchers claim that pre-service teachers should already be provided with basic knowledge, skills, and methods for teaching curriculum-based content outdoors in their initial schoolteacher training. The present review aims to summarize and structure the variety of topics in the literature regarding outdoor teaching in initial formal schoolteacher training. We analyzed the general characteristics of 46 empirical studies from different regions that investigate skills, content areas, and pedagogical strategies to prepare pre-service teachers from early childhood to secondary education for teaching outdoors. We used deductive-inductive content analysis to identify categories and emerging themes. We identified eight themes in the reviewed studies, of which we detail and discuss the four most frequently mentioned: collaboration, creativity, strategies for outdoor learning and sustainability. We discuss the implications for further research and for teacher training.

description: We calculate the cobordism ring of stably almost complex manifolds with involution, and investigate the equivariant spectrum which represents it. We introduce the notion of geometrically oriented spectra, which extends the notion of complex oriented spectra, and of which the geometric cobordism spectrum is the universal example. Other examples of geometrically oriented spectra include the Eilenberg-Maclane spectrum associated to a constant Mackey functor, and the connective cover of equivariant complex K theory. On the algebraic side, we define and study filtered equivariant formal group laws, which are the algebraic structures determined by geometrically oriented spectra. We prove some of the fundamental properties of filtered equivariant formal group laws, as well as a universality statement for the filtered equivariant formal group law determined by the geometric complex cobordism spectrum.
