description: Quasi-periodic oscillations and dwarf nova oscillations occur in dwarf novae and nova-like variables during outburst and occasionally during quiescence, and have analogues in high-mass X-ray binaries and black-hole candidates. The frequent low coherence of quasi-period oscillations and dwarf nova oscillations can make detection with standard time-series tools such as periodograms problematic. This paper develops tools to analyse quasi-periodic brightness oscillations. We review the use of time-frequency representations in the astronomical literature, and show that representations such as the Choi-Williams Distribution and Zhao-Atlas-Marks Representation, which are best suited to high signal-to-noise data, cannot be assumed a priori to be the best techniques for our data, which have a much higher noise level and lower coherence. This leads us to a detailed analysis of the time-frequency resolution and statistical properties of six time-frequency representations. We conclude that the wavelet scalogram, with the addition of wavelet ridges and maxima points, is the most effective time-frequency representation for analysing quasi-periodicities in low signal-to-noise data, as it has high time-frequency resolution, and is a minimum variance estimator. We use the wavelet ridges method to re-analyse archival data from VW Hyi, and find 62 new QPOs and 7 new long-period DNOs. Relative to previous analyses, our method substantially improves the detection rate for QPOs.

description: The Ejido of Tzurumútaro is within the municipality of Pátzcuaro in the central part of the state of Michoacán, Mexico. An ejido is an agrarian settlement with a community-based land tenure system, which is common in Mexico. The Ejido of Tzurumútaro in particular, has a historical significance in the Lake of Pátzcuaro region, because it played an important role during the post-revolutionary land reform. The objective of this study is to describe the structure of the biophysical landscapes of this agrarian settlement. To accomplish this, biblio-cartographic data collection of biophysical components was done, which included information on geology, lithology, hydrology, climate, and pedology. Three taxonomic units were defined; specifically, five superior units or localities; nine Land areas and 30 Sub-land areas. Landscapes of volcanic origin are widely prevalent, although geo-systems of river and lake origin are also present. The map constitutes an important basic information basis on landscape units.

description: Using recently developed techniques based on scattering theory, we find the electromagnetic Casimir energy for geometries involving semi-infinite planes, a case that is of particular interest in the design of microelectromechanical devices. We obtain both approximate analytic formulae and exact results requiring only modest numerical computation. Using these results, we analyze the effects of edges and orientation on the Casimir energy. We also demonstrate the accuracy, simplicity, and utility of our approximation scheme, which is based on a multiple reflection expansion.

The Theory of Two-Electron Atoms: From the Ground State to Complete Fragmentation

Subjects: subject: 530 Physik

description: Since the first attempts to calculate the helium ground state in the early days of Bohr-Sommerfeld quantization, two-electron atoms have posed a series of unexpected challenges to theoretical physics. Despite the seemingly simple problem of three charged particles with known interactions, it took more than half a century after quantum mechanics was established to describe the spectra of two-electron atoms satisfactorily. The evolution of the understanding of correlated two- electron dynamics and its importance for doubly excited resonance states is presented here, with an emphasis on the concepts introduced. The authors begin by reviewing the historical development and summarizing the progress in measuring the spectra of two-electron atoms and in calculating them by solving the corresponding Schrödinger equation numerically. They devote the second part of the review to approximate quantum methods, in particular adiabatic and group- theoretical approaches. These methods explain and predict the striking regularities of two-electron resonance spectra, including propensity rules for decay and dipole transitions of resonant states. This progress was made possible through the identification of approximate dynamical symmetries leading to corresponding collective quantum numbers for correlated electron-pair dynamics. The quantum numbers are very different from the independent particle classification, suitable for low-lying states in atomic systems. The third section of the review describes modern semiclassical concepts and their application to two-electron atoms. Simple interpretations of the approximate quantum numbers and propensity rules can be given in terms of a few key periodic orbits of the classical three-body problem. This includes the puzzling existence of Rydberg series for electron-pair motion. Qualitative and quantitative semiclassical estimates for doubly excited states are obtained for both regular and chaotic classical two-electron dynamics using modern semiclassical techniques. These techniques set the stage for a theoretical investigation of the regime of extreme excitation towards the three- body breakup threshold. Together with periodic orbit spectroscopy, they supply new tools for the analysis of complex experimental spectra.

description: I miss seeing family - most of mine live in London and I'm not allowed to travel to see them. My mother is carefully locked down in her care home, so there's no question of visiting her. One lovely carer lets us use her WhatsApp account to video-call, which sometimes works if they have remembered to switch off the TV and checked that Granny has her hearing aids in. She finds the small moving pictures on the phone difficult to understand, but we both enjoy hearing one another's voices even if we only exchange easy-to-understand platitudes.
Memories and imaginings : learning to prefigure how the mountains become the bluffs
Creators: name: Frattura-Kampschroer, Addyson
Publisher: name: University of British Columbia
Year: 2018

description: Addyson Frattura-Kampschroer’s thesis is made within the tradition of humanities-based research. The thesis is a form of literary philosophy that practices pre-qualitative methods. Frattura-Kampschroer’s work is in partial fulfilment for the degree of Master of Arts in Educational Studies at the University of British Columbia. The thesis is a form of literary philosophy insofar as it is a philosophical work written in the literary form of a narrative. In essence, the claims are made narratively and then supported and analyzed throughout the use of metaphors, themes, and figures. The narrative is comprised of childhood vignettes of the rural Midwest. The vignettes carry the concepts through to provide particular sites for questioning and conceptualizing. Frattura-Kampschroer functions as the narrator as she tells stories in the style of creative non-fiction. However, the narrator, places, and stories are not of primary importance; they and unimportant things in unimportant places. What is of extreme importance are the concepts: prefigurative politics and freedom. Rather than addressing the concepts qualitatively, in the methodological style of the social sciences, the narrative itself is the method. More specifically, the thesis utilizes a pre-qualitative method. Finally, the narrative also exposes the pedagogical experience of a continually evolving learner, a learner who questions the context in which they are questioning. The supervisory committee is formed by four faculty members from the University of British Columbia. The committee is comprised of: Carl Leggo, Vanessa de Oliveira Andreotti, William Pinar, and the primary supervisor being Sam Rocha.

description: A 1:50,000 hydrogeological map of the Pale di San Martino Mountains (Northern Italy) was created. The map presents the merge of various pre-existing data with new field data collected between the years 2014 and 2016. Through the use of symbols and specific colours, the map shows various groundwater-related data such as the hydrogeological complexes, the location and size of the main springs, the extension of the recharge areas, the hydrogeological boundaries, as well as information on groundwater usage. Given the absence of hydrogeological maps in the entire mountain range of the Dolomites, the approach followed in this study could be used as a guide for future representations in this alpine region. At the local scale, the map could serve as a conceptual base for future research involving groundwater and for water management planning.

description: The aim of this study was to identify and characterize the main plant communities in a temperate coastal wetland using high-resolution imagery. We produced a map of Samborombón Bay at 1:25,000 scale using a WorldView-2 image. An Object-based Image Analysis approach was chosen, and an unsupervised classification algorithm was applied. Overall classification accuracy was 81%, and the Kappa index was 78.1%. Six land cover types were mapped including four main natural monospecific plant communities. The lower intertidal area was dominated by mudflats without vegetation and stands of Bolboschoenus maritimus. The middle intertidal area was dominated by Sarcocornia ambigua, while, in the higher intertidal area, Sporobolus densiflorus and grasslands with Cortaderia selloana prevailed. We found four spatial patterns at a landscape scale, based on the presence and spatial distribution of the natural plant communities. This map represents a valuable tool for future studies on wetland environmental indicators.

description: We construct four-dimensional covariant non-linear theories of massive gravity which are ghost-free in the decoupling limit to all orders. These theories resum explicitly all the nonlinear terms of an effective field theory of massive gravity. We show that away from the decoupling limit the Hamiltonian constraint is maintained at least up to and including quartic order in non-linearities, hence, excluding the possibility of the Boulware-Deser ghost up to this order. We also show that the same remains true to all orders in a similar toy-model.

description: The extensive analysis of remote-sensed data (among which ALS-derived images) and fieldwork carried out in the Trieste Karst (N–E Italy) have shed light on archaeological landscapes largely unknown until recent years. The chronological definition of this complex palimpsest was based on the collection of findings associated to the archeological evidence, shape and orientation of detected structures and stratigraphic relations among features. This allowed to evaluate the interplay between landforms through time and to reconstruct some long-term economic strategies pursued by past communities. As a result, we present a 1:5000 map of the easternmost sector of the Trieste area, next to the border between Italy and Slovenia, approximately corresponding to the area of the map Carta Tecnica Regionale ‘Grozzana’. The map aims at providing a tool for the protection of the cultural and environmental heritage, land use planning and touristic valorization of the area.

description: Triangular arrays of Ni nanotriangles embedded in superconducting Nb films exhibit unexpected dynamical vortex effects. Collective pinning with a vortex lattice configuration different from the expected fundamental triangular "Abrikosov state" is found. The vortex motion which prevails against the triangular periodic potential is produced by channelling effects between triangles. Interstitial vortices coexisting with pinned vortices in this asymmetric potential, lead to ratchet reversal, i.e. a DC output voltage which changes sign with the amplitude of an applied alternating drive current. In this landscape, ratchet reversal is always observed at all magnetic fields (all numbers of vortices) and at different temperatures. The ratchet reversal is unambiguously connected to the presence of two locations for the vortices: interstitial and above the artificial pinning sites.

description: The sand islands and shore-attached dune fields of south east Queensland form the world’s oldest and largest coastal sand dune system. Here we present updated morphological maps for the dune fields based on topographic expression and geomorphic relationships. Individual dunes were delineated using high-resolution elevation data and were grouped into morphosequences based on the elevation, drainage characteristics and slope characteristics of the individual dunes. The slope characteristics focussed on high resolution derived slope-curvature and slope-elevation parameters. Morphosequences were recognised from cross-cutting relationships and relative position in the dune field. Our method was developed for the Cooloola Sand Mass and then applied to Fraser Island, Moreton Island and North Stradbroke Island, the other major sand islands in south east Queensland. In total, five Holocene and four Pleistocene units have been identified. The new mapping underpins current work on the geomorphic evolution of the dune fields.

description: Classical T Tauri stars (CTTS) are young, late-type objects, that still accrete matter from a circumstellar disk. Analytical treatments and numerical simulations predict instabilities of the accretion shock on the stellar surface. We search for variability on timescales below a few minutes in the CTTS TW Hya and AA Tau. TW Hya was observed with SALTICAM on the Southern African Large Telescope (SALT) in narrow-band filters around the Balmer jump. The observations were performed in slit mode, which provides a time resolution of about 0.1 s. For AA Tau we obtained observations with OPTIMA, a single photon-counting device with even better time resolution. Small-scale variability typically lasts a few seconds, however, no significant periodicity is detected. We place a 99 % confidence upper limit on the pulsed fraction of the lightcurves. The relative amplitude is below 0.001 for TW Hya in the frequency range 0.02-3 Hz in the 340 nm filter and 0.1-3 Hz in the 380 nm filter. The corresponding value for AA Tau is an amplitude of 0.005 for 0.02-50 Hz. The relevant timescales indicate that shock instabilites should not be seen directly in our optical and UV observations, but the predicted oscialltions would induce observable variations in the reddening. We discuss how the magnetic field could stabilise the accretion shock.

description: In this paper, the annual rainfall and temperature values, measured in the period 1951-2016 in a region of southern Italy (Calabria), have been spatially interpolated using deterministic and geostatistical techniques in an R environment. In particular, Inverse Distance Weighting (IDW), Ordinary Kriging (OK), Kriging with External Drift (KED) and Ordinary Cokriging (COK) were compared to evaluate the best suitability method in reproducing the actual surface. Then, the spatial variation of aridity in Calabria has been evaluated using the De Martonne aridity index (IDM), which is based on rainfall and temperature data. As a result, geostatistical methods incontrovertibly show a better estimate than the IDW. Specifically, the KED was identified as the best predictor method for both rainfall and temperature data. Moreover, the spatial distribution of the IDM evidenced that the majority of the study area can be classified as humid, with semi–arid conditions mainly identified in the coastal areas.
Calculation of the substitutional fraction of ion-implanted He in an Fe target

Year: 2010

description: Ion-implantation is a useful technique to study irradiation damage in nuclear materials. To study He effects in nuclear fusion conditions, He is co-implanted with damage ions to reproduce the correct He/dpa ratios in the desired or available depth range. However, the short-term fate of these He ions, i.e over the time scales of their own collisional phase, has not been yet unequivocally established. Here we present an atomistic study of the short-term evolution of He implantation in an Fe substrate to approximate the conditions encountered in dual ion-implantation studies in ferritic materials. Specifically, we calculate the fraction of He atoms that end up in substitutional sites shortly after implantation, i.e. before they contribute to long-term miscrostructural evolution. We find that fractions of at most 3% should be expected for most implantation studies. In addition, we carry out an exhaustive calculation of interstitial He migration energy barriers in the vicinity of matrix vacancies and find that they vary from approximately 20 to 60 meV depending on the separation and orientation of the He-vacancy pair.

description: Pockmarks are seabed depressions that represent primary evidence of rapid biogenic/thermogenic gas build up and fluid release from seabed sediments to the water column. We use a Geographical Information System (GIS) to analyse multibeam echo-sounder bathymetric data and use a range of semi-automated tools to map seabed pockmarks in fjords and adjacent coastal waters around western Scotland. We map 1019 individual pockmarks in 12 different hydrographic areas covering ca. 2019 km2. We use morphological metrics and statistical procedures to classify and analyse the variety of pockmark forms. A k-means clustering algorithm identifies three classes of pockmark morphology: deep, elongate and regular. The recognition of separate pockmark classes could aid understanding of their age, activity and origin. This work presents the first detailed mapping of pockmark fields in Scottish west coast waters and highlights the use of pockmarks as an indicator of the quantity, mobility and fate of stored carbon.

Social Emotional Learning beliefs of preservice teachers : measuring the impact of a teacher education program
Creators: name: Gist, Alexander
Publisher: name: University of British Columbia
Year: 2018

description: The importance of Social Emotional Learning (SEL) for success in school and the workplace is increasingly being recognized. Often, teachers are the ones tasked with implementing SEL programming and promoting it in the classroom. Yet, though future teachers will be expected to promote SEL, little attention is given to SEL in teacher education programs and there is a dearth of research on SEL in teacher education. The teacher education program at the University of British Columbia (UBC) has a unique cohort of its elementary education program that focuses on SEL. This study examined changes in teacher self-efficacy, teaching beliefs and priorities, especially with regard to SEL, among students completing their teacher education program. Preservice teachers in the SEL cohort were compared with students in other cohorts. Students (n = 102) in four different cohorts of the teacher education program were surveyed at the beginning and the end of the academic year to measure change in self-efficacy over time and between cohorts. Overall, the self-efficacy of students in the teacher education program improved in all areas measured over the course of the program. On SEL-focused subscales, students in the SEL cohort reported the highest self-efficacy, though, in general, the SEL cohort students did not improve significantly more over the course of the year than students in other cohorts. In fact, on the subscale measuring self-efficacy for preventing behavioral problems before they occur, though students in the SEL cohort had the highest self-efficacy, other cohorts showed greater improvements over the course of the year. Results suggest that after taking part in UBC’s teacher education program, preservice teachers, regardless of their cohort, report higher self-efficacy in both academic and SEL-related areas regardless of the cohort.

description: We have developed a Nagel-Schreckenberg cellular automata model for describing of vehicular traffic flow at a single intersection. A set of traffic lights operating in fixed-time scheme controls the traffic flow. Open boundary condition is applied to the streets each of which conduct a uni-directional flow. Streets are single-lane and cars can turn upon reaching to the intersection with prescribed probabilities. Extensive Monte Carlo simulations are carried out to find the model flow characteristics. In particular, we investigate the flows dependence on the signalisation parameters, turning probabilities and input rates. It is shown that for each set of parameters, there exist a plateau region inside which the total outflow from the intersection remains almost constant. We also compute total waiting time of vehicles per cycle behind red lights for various control parameters.

A study of the developmental activities that describe highly elite men and women soccer players and the relation of these activities to indices of motivation, soccer related skills and progressions.
Creators: name: Hendry, David T.
Publisher: name: University of British Columbia
Year: 2018

description: A multivariable measurement approach was used to determine relationships between talent development pathways in soccer and outcomes related to future elite success, soccer skill ratings and motivation. In Study 1, elite “Academy” youth soccer players in the UK were followed over 5-years to ascertain the developmental activities that distinguished players which progressed to youth and adult professional levels. Professional players followed an early majority engagement pathway characterized by predominant involvement in high volumes of soccer practice and play (i.e., self-led activities) from an early age. They participated in other sports but the majority time was in soccer. Adult professional players accumulated more hours in soccer play compared to youth professionals, but not practice. In Study 2, coach ratings of soccer skills were related to attainment of youth and adult professional status. Coach ratings of technical, tactical and creative skill were higher in players that achieved professional youth status, versus de-selected academy players. Only tactical skill, and somewhat, technical skill, differentiated adult from youth professionals. Technical and tactical skill ratings were primarily related to hours in soccer practice, but there were no relations to hours in play. In Study 3, practice amounts were related to markers of self-determined motivation (SDM) but soccer play hours were not related to SDM. Through comparisons with recreational, age-matched soccer players, SDM was shown to become less self-determined from 15 -17 yr, but only among elite players. In Study 4, the developmental pathways engaged in by elite (National-team) and sub-elite (Varsity) adult women soccer players were assessed. National players followed an early majority engagement pathway, engaging in more soccer play than sub-elites, which was also rated as more challenging. In summary, success in elite soccer is characterized by an early, majority engagement pathway consisting of early childhood involvement in soccer, relatively high volumes of practice and play, and majority time in soccer, in comparison to other sports.

We demonstrate for systems with uniformly hyperbolic dynamics that including off-diagonal contributions to double sums over classical paths gives a weak-localization correction in quantitative agreement with results from random matrix theory. We further discuss the magnetic-field dependence. This semiclassical treatment accounts for current conservation.

description: Accuracy of throwing in games and sports is governed by how errors at projectile release are propagated by flight dynamics. To address the question of what governs the choice of throwing strategy, we use a simple model of throwing with an arm modelled as a hinged bar of fixed length that can release a projectile at any angle and angular velocity. We show that the amplification of deviations in launch parameters from a one parameter family of solution curves is quantified by the largest singular value of an appropriate Jacobian. This allows us to predict a preferred throwing style in terms of this singular value, which itself depends on target location and the target shape. Our analysis also allows us to characterize the trade-off between speed and accuracy despite not including any effects of signal-dependent noise. Using nonlinear calculations for propagating finite input-noise, we find that an underarm throw to a target leads to an undershoot, but an overarm throw does not. Finally, we consider the limit of the arm-length vanishing, i.e. shooting a projectile, and find that the most accurate shooting angle bifurcates as the ratio of the relative noisiness of the initial conditions crosses a threshold.

description: The Gaick is an enigmatic glaciated landscape in the Central Grampians, Scotland, dominated by an expansive dissected plateau. Previous studies have postulated widely differing interpretations of the glacial landforms and current understanding of the glacial events in this area is partly restricted by the absence of detailed glacial geomorphological mapping. To address this issue, we present a comprehensive 1: 46,000-scale glacial geomorphological map, covering an area of ∼520 km2. A combination of detailed field mapping and interpretation of aerial photographs and Digital Surface Models (DSMs) has revealed a variety of glacial, periglacial and fluvial landforms, including an abundance of moraines and meltwater channels within valleys. We also identify a glacial sediment-landform assemblage, dissected glaciogenic material, that has not previously been reported in the Scottish Highlands. The geomorphological map provides the necessary foundation for elucidating the extent, dynamics and timing of former glaciation in the area.

description: Stellar density and bar strength should affect the temperatures of the cool (T ~ 20-30 K) dust component in the inner regions of galaxies, which implies that the ratio of temperatures in the circumnuclear regions to the disk should depend on Hubble type. We investigate the differences between cool dust temperatures in the central 3 kpc and disk of 13 nearby galaxies by fitting models to measurements between 70 and 500 microns. We attempt to quantify temperature trends in nearby disk galaxies, with archival data from Spitzer/MIPS and new observations with Herschel/SPIRE, which were acquired during the first phases of the Herschel observations for the KINGFISH (key insights in nearby galaxies: a far-infrared survey with Herschel) sample. We fit single-temperature modified blackbodies to far-infrared and submillimeter measurements of the central and disk regions of galaxies to determine the temperature of the component(s) emitting at those wavelengths. We present the ratio of central-region-to-disk-temperatures of the cool dust component of 13 nearby galaxies as a function of morphological type. We find a significant temperature gradient in the cool dust component in all galaxies, with a mean center-to-disk temperature ratio of 1.15 +/- 0.03. The cool dust temperatures in the central ~3 kpc of nearby galaxies are 23(+/-3)% hotter for morphological types earlier than Sc, and only 9(+/-3)% hotter for later types. The temperature ratio is also correlated with bar strength, with only strongly barred galaxies having a ratio over 1.2. The strong radiation field in the high stellar density of a galactic bulge tends to heat the cool dust component to higher temperatures, at least in early-type spirals with relatively large bulges, especially when paired with a strong bar.

description: The similarities between string percolation and Glasma results are emphasized, special attention being paid to rapidity long range correlations, ridge structure and elliptic flow. As the string density of high multiplicity pp collisions at LHC energies has similar value as the corresponding to Au-Au semi-central collisions at RHIC we also expect in pp collisions long rapidity correlations and ridge structure, extended more than 8 units in rapidity.

description: This paper presents an innovative multi-thematic map (1:2500) that integrates morpho-sedimentological data, hydrodynamic processes, seasonal morphodynamic transitions and the distribution of the benthic habitat of a Mediterranean microtidal, wave-dominated gravel beach system. It is part of a larger cartography of coastal areas, and is based on an interdisciplinary sea-land approach that is applicable worldwide and aims to facilitate coastal management practices and future scientific research. The applications to coastal management include: the facilitation of coastal vulnerability assessments; easy-to-access, up-to-date digital geospatial data; and baseline studies for the future assessment and monitoring of environmental changes. The main environmental features that control the marine processes of this gravel beach appear to be linked to geological and morphological contexts such as the presence of the river mouth, the outcropping of a beach-rock along the coastline, the deposition of gravelly sediment in the beachface and the seagrass cover.

description: The results of geomorphological investigations carried out in the Rio Cisles basin in the Odle Group (Italian Alps) are presented. This is one of the most famous and spectacular mountain groups of the Dolomites, located in the north-western sector of the Gardena valley, an area of high tourism appeal. Field surveys and multitemporal aerial-photo interpretation led to the production of a geomorphological map at a 1:12,000 scale. This map outlines the features of an area of about 20 km2, characterised by high relief energy, mainly due to the overlapping of large dolomite rocks masses on clayey rocks. The present morphology is the result of intense postglacial and paraglacial geomorphic activity, which has affected the area since the Upper Pleistocene. The geomorphological evolution of this area has been reconstructed and a new contribution is given to the comprehension of the geomorphology of the eastern Dolomites.
