description: The dispersion of the composite-fermion cyclotron-resonance mode is measured with an optical detection scheme under the combined excitation of microwave radiation and a surface acoustic wave from an interdigital transducer. The slowly traveling surface wave defines the transferred wave vector. Momenta up to 108 m-1 are accessible. The cyclotron-resonance mode exhibits strong negative dispersion, which suggests predominant short range residual interaction among composite fermions. From an extrapolation, the cyclotron mass at k=0 is obtained and investigated as a function of electron density.

description: Particle learning (PL) provides state filtering, sequential parameter learning and smoothing in a general class of state space models. Our approach extends existing particle methods by incorporating the estimation of static parameters via a fully-adapted filter that utilizes conditional sufficient statistics for parameters and/or states as particles. State smoothing in the presence of parameter uncertainty is also solved as a by-product of PL. In a number of examples, we show that PL outperforms existing particle filtering alternatives and proves to be a competitor to MCMC.

Transient beam loading studies in radiofrequency cavities

Publisher: name: University of British Columbia

description: RF cavities are the driving technology behind most of modern particle accelerators. The diverse use of RF cavities in linear accelerators for are discussed and experiments have been performed to illustrate these principles. Experiments were conducted at two Rare-Isotope Beam facilities: GSI in Germany, and TRIUMF in Canada. More specifically, linear accelerators investigated are GSI UNILAC and 0.5 MW Superconducting electron LINAC, currently constructed and commissioned at TRIUMF as part of the ARIEL Project. Measurements at GSI UNILAC were performed parasitically while at TRIUMF, access to different beamline sections is available and dedicated measurements have been undertaken at both the low and medium energy sections of the LINAC. A main focus is to study beam-cavity interactions, in particular the effect of beam-loading. This effect acts back on the beam via induced resonance of the cavity, and can have negative effects on the beam, such as the increase of beam energy dispersion. This interaction can be explained using an equivalent circuit model. In Superconducting RF cavities, cavity voltage is controlled via a feedback loop. In pulsed beam operation, however, due to the high quality factor of the SRF cavity, feedback control alone is not adequate to compensate for the beam-loading effect and an additional feedforward control signal needs to be implemented. Combining experiments at GSI and TRIUMF, this effect is discussed in detail via RF cavity response to beam-driven, generator-driven, and with closed-loop control feedback and feed-forward, using RF signal analysis, beam diagnostics measurements, and dipole magnets. On top of beam-loading effects, the bunch length output of the ARIEL electron gun has also been studied with a deflecting cavity. Additional measurements with a buncher cavity have also been performed as a follow- up of the issues discovered during beam-loading measurements with ARIEL EINJ (injector cryomodule). The results obtained from both measurements indicate the necessity to improve the timing architecture of the ARIEL e-LINAC. A portion of the Appendix is dedicated to illustrate RF superconductivity and RF eigenmode simulation with commercial RF codes in order to explain the different modes of RF cavity operations applied throughout this thesis.

description: Minimal unitary representation of SO*(8) = SO(6,2) realized over the Hilbert space of functions of five variables and its deformations labeled by the spin t of an SU(2) subgroup correspond to massless conformal fields in six dimensions as was shown in arXiv:1005.3580. In this paper we study the minimal unitary supermultiplet of OSp(8*|2N) with the even subgroup SO*(8) x USp(2N) and its deformations using quasiconformal methods. We show that the minimal unitary supermultiplet of OSp(8*|2N) admits deformations labeled uniquely by the spin t of an SU(2) subgroup of the little group SO(4) of lightlike vectors in six dimensions. We construct the deformed minimal unitary representations and show that they correspond to massless 6D conformal supermultiplets. The minimal unitary supermultiplet of OSp(8*|4) is the massless supermultiplet of (2,0) conformal field theory that is believed to be dual to M-theory on AdS_7 x S^4. We study its deformations in further detail and show that they are isomorphic to the doubleton supermultiplets constructed by using twistorial oscillators.

THE INFLUENCE OF FEEDBACK ON COMPREHENSION IN MIDDLE SCHOOL STUDENTS: A COMPREHENSIVE ANALYSIS
Creators: name: Satibaldieva, Nigora

Year: 2025

description: This thesis examines the influence of feedback on comprehension among middle school students. Feedback, as a dynamic educational tool, has been shown to play a critical role in shaping students’ understanding, motivation, and overall academic performance. This study synthesizes current literature and proposes a conceptual model to illustrate how various types of feedback – formative, summative, immediate, and delayed – affect comprehension at the middle school level. Through a detailed literature review, analysis of classroom practices, and a discussion of empirical studies, this paper highlights the conditions under which feedback is most effective. Findings suggest that timely, specific, and actionable feedback not only bolsters comprehension but also promotes self-regulated learning and academic growth. Implications for educators include the integration of targeted feedback strategies into daily instructional practices and the adoption of continuous assessment methods that support student learning. Future research should explore longitudinal effects and the interaction between feedback modalities and diverse learner characteristics.
title: Reference-Related Speaker Gaze as a Cue in Online Sentence Processing

description: We report a series of eye-tracking studies investigating different facets of how seeing a speaker’s gaze affects listeners’ visual attention and comprehension. We compare the effect of speaker gaze to other cues in the linguistic and non-linguistic context, such as depicted actions and sentence structure. In addition, we discuss top-down influences of the comprehension sub-task, as well as the similarities and differences between using the gaze of a human speaker and that of an artificial agent. Our results suggest that human listeners rapidly make use of speaker gaze as a cue to upcoming conversational content, and that this benefit generalises across a range of situations. At the same time, the extent of gaze-following is affected by sentence structure. These findings are important for processing accounts and models of situated language comprehension, but they also contribute to developing communicative agents that behave in a natural and human-like way.
Sustainability and indigenous worldviews : a circle of beauty and wisdom from Mother Earth's Children's Charter School
Creators: name: Amber, Candice Anita
Publisher: name: University of British Columbia
Year: 2018

description: This qualitative study celebrates Mother Earth’s Children’s Charter School (MECCS), the first public Indigenous charter school in Canada and their Cree and Stoney Indigenous worldviews and Indigenous learners. This study reveals a sustainability ethos at the heart of their Cree and Stoney worldview as Sustainability is: “We are Mother Earth” and Sustainability is: “Relationality or Relationship”. The Cree and Stoney languages have no exact words for sustainability but rather deeply held beliefs that reveal a sustainability ethos through a circle of beauty and wisdom. The purpose of this study is to explore an enhanced and relational ethos of sustainability through respect for spirit, place, and humanity throughout non-mainstream worldviews (e.g. Indigenous). This study offers a broader concept of a sustainability ethos than the more limited European, Western, dominant definitions of sustainability that focus on variations of the pillars of people, place, and profit (e.g. commodity). The concept of sustainability cannot be compartmentalized because all people, livelihoods, and the planet are one and connected through relationships in life in the medicine wheel, circle of life, and seven sacred teachings. Therefore, this study replaces the notions of pillars with the circle of beauty and wisdom from the Cree and Stoney worldview as practiced and lived at MECCS. The circle of beauty and wisdom reveals the MECCS sustainability ethos as wisdom-on-the-ground experiences that celebrate thriving learners, the planet Mother Earth, and livelihoods. By foregrounding the circle of beauty and wisdom of Indigenous worldviews and validating Indigenous worldviews as equal to non-Indigenous worldviews makes possible the potential for a broader discourse of sustainability. As a non-Indigenous teacher with several years of involvement with Aboriginal Education, I deeply value and respect Indigenous perspectives. This study extends an invitation to learn from Cree and Stoney (Treaty 6) Indigenous worldviews at MECCS. For the purpose of this study, aspects of Appreciative Inquiry and Indigenous Methodologies are used to interview Indigenous and non-Indigenous adult participants to explore Cree and Stoney worldviews as lived and practiced at MECCS.

description: We observed the ultra-compact binary candidate 4U 0614+091 for a total of 200 ksec with the high-energy transmission gratings onboard the \chandra X-ray Observatory. The source is found at various intensity levels with spectral variations present. X-ray luminosities vary between 2.0$\times10^{36}$ \ergsec and 3.5$\times10^{36}$ \ergsec. Continuum variations are present at all times and spectra can be well fit with a powerlaw component, a high kT blackbody component, and a broad line component near oxygen. The spectra require adjustments to the Ne K edge and in some occasions also to the Mg K edge. The Ne K edge appears variable in terms of optical depths and morphology. The edge reveals average blue- and red-shifted values implying Doppler velocities of the order of 3500 \kms. The data show that Ne K exhibits excess column densities of up to several 10$^{18}$ cm$^{-2}$. The variability proves that the excess is intrinsic to the source. The correponding disk velocities also imply an outer disk radius of the order of $< 10^9$ cm consistent with an ultra-compact binary nature. We also detect a prominent soft emission line complex near the \oviii L$α$ position which appears extremely broad and relativistic effects from near the innermost disk have to be included. Gravitationally broadened line fits also provide nearly edge-on angles of inclination between 86 and 89$^{\circ}$. The emissions appear consistent with an ionized disk with ionization parameters of the order of 10$^4$ at radii of a few 10$^7$ cm. The line wavelengths with respect to \oviiia\ are found variably blue-shifted indicating more complex inner disk dynamics.

description: We observe an experimental signature of the role of phonons in spin relaxation between triplet and singlet states in a two-electron quantum dot. Using both the external magnetic field and the electrostatic confinement potential, we change the singlet-triplet energy splitting from 1.3 meV to zero and observe that the spin relaxation time depends nonmonotonously on the energy splitting. A simple theoretical model is derived to capture the underlying physical mechanism. The present experiment confirms that spin-flip energy is dissipated in the phonon bath.

description: Using atomistic computer simulations, we study how ion irradiation can be used to alter the morphology of a graphene monolayer by introducing defects of specific type, and to cut graphene sheets. Based on the results of our analytical potential molecular dynamics simulations, a kinetic Monte Carlo code is developed for modelling morphological changes in a graphene monolayer under irradiation at macroscopic time scales. Impacts of He, Ne, Ar, Kr, Xe and Ga ions with kinetic energies ranging from tens of eV to 10 MeV and angles of incidence between 0\circ and 88\circ are studied. Our results provide microscopic insights into the response of graphene to ion irradiation and can directly be used for the optimization of graphene cutting and patterning with focused ion beams.

Detecting novel climates in projections of 21st century terrestrial ecosystem change
Creators: name: Mahony, Colin
Publisher: name: University of British Columbia
Year: 2018

description: The emergence of locally unfamiliar climates due to anthropogenic global warming is compelling scientists and resource managers to seek ecological data and management strategies from non-local climates, known as climate analogs. In this context, novel climates—emerging conditions with no analog in the observational record—represent widening gaps in the ecological knowledge base. Identification of novel climates is essential to climate change adaptation. However, methods to detect novel climates have not kept pace with this necessity. The goal of this dissertation is to advance methods for detection of novel climates in the context of ecology and forest management. I develop a multivariate metric for climatic novelty, sigma dissimilarity, that uses the local historical range of interannual climatic variability as a scale for measuring the ecological significance of climatic differences. I apply this metric at three scales—continental, jurisdictional, and local—each of which offers a distinct perspective on the implications of climatic novelty. At the continental scale, I assess the emergence of novel climates in North America, where they are an important source of extrapolation error in ecological modeling. I demonstrate the potential for novel climates to emerge throughout the continent, particularly at low topographic positions. At the jurisdictional scale, I assess the emergence of novel climates that are not represented in a structured knowledge system for forest management—the Biogeoclimatic Ecosystem Classification for British Columbia. A parallel novelty assessment using sigma dissimilarity and random forest classification indicates a robust pattern of novel climates in BC, for which analogs from outside BC must be identified. At the local scale, I demonstrate that dependencies among climate variables can produce larger and earlier departures from natural variability than is detectable in individual variables. This multivariate departure intensification effect—evident in distinct regions of the planet in global climate models—indicates adaptive challenges for ecological and human communities as their local climates become unfamiliar. The identification of locally unfamiliar and regionally novel climates is an important step in anticipating and adapting to climate change. Further, the challenges presented by novel climates are yet another basis to advocate for global emissions reductions.

description: We review a number of experimental techniques that are beginning to reveal fine details of the bosonic spectrum α^2F(Ω) that dominates the interaction between the quasiparticles in high temperature superconductors. Angle-resolved photo emission (ARPES) shows kinks in electronic dispersion curves at characteristic energies that agree with similar structures in the optical conductivity and tunnelling spectra. Each technique has its advantages. ARPES is momentum resolved and offers independent measurements of the real and imaginary part of the contribution of the bosons to the self energy of the quasiparticles. The optical conductivity can be used on a larger variety of materials and with the use of maximum entropy techniques reveals rich details of the spectra including their evolution with temperature and doping. Scanning tunnelling spectroscopy offers spacial resolution on the unit cell level. We find that together the various spectroscopies, including recent Raman results, are pointing to a unified picture of a broad spectrum of bosonic excitations at high temperature which evolves, as the temperature is lowered into a peak in the 30 to 60 meV region and a featureless high frequency background in most of the materials studied. This behaviour is consistent with the spectrum of spin fluctuations as measured by magnetic neutron scattering. However, there is evidence for a phonon contribution to the bosonic spectrum as well.

We have performed the calculations for physical values of the strange quark mass $m_s$ and the light quark masses $m_l=0.2m_s$ and $0.05m_s$. Several finite temperature observables, including the renormalized Polyakov loop, the renormalized chiral condensate and the chiral susceptibility have been calculated. We also study the fluctuations and correlations of different conserved charges as well as the trace anomaly at finite temperature. We compare our findings with previous calculations that use different improved staggered fermion formulations: asqtad, p4 and stout.

description: Cleaved Edge Overgrowth is employed to fabricate atomically precise single and coupled quantum wires. Single wires were investigated in the diffusive and ballistic transport regimes. In addition to a detailed understanding of the 1D sublevel structure in the complex CEO devices, clear indications of Luttinger liquid behavior of the one-dimensional electron systems were obtained. Coupled quantum wires were studied in the two limits of large and small separations. In the first case shallow 1D potentials were chosen and an alternative description for commensurability oscillations in weakly modulated two-dimensional electron systems could be derived. For the coupled quantum wires with small separations and a large potential modulation the validity of the miniband transport picture leading to negative differential conductivity was demonstrated.

Similar considerations can be applied to the effective potential V for a scalar field phi; here the log independent pieces are fixed by the condition V'(phi=v)=0.

The resulting very broad X(4260) structure does not seem to classify itself as a vector charmonium resonance, but its detailed shape allows to identify new vector c-cbar states. Here, we estimate the resonance parameters of the psi(3D) state.

description: We report on a semiconductor-superlattice oscillator with a superlattice electronic device (SLED) containing superlattices connected in parallel and series as active elements for generation of millimetre waves. We present experimental results indicating that parallel connected superlattices can lead, compared to a single superlattice as the active element, to an increase of the output power of the oscillator. Studies of blocks of parallel connected superlattices in series lead us to propose using a SLED with parallel and serially connected superlattices as an active element. Our superlattice oscillator, with different arrangements of superlattice mesas in a quasiplanar design, operated in the frequency range of around 100 GHz. It was electrically tunable and delivered microwave power of about 0.1 mW.

We survey a variety of possible behaviours, including some where the walk is eventually confined to an interval of large length. We also focus on certain "asymmetric" drifts, where we prove that with positive probability, the walks behave deterministically on large scale and move like a constant times the square root of time, or like a constant times the logarithm of time.

description: Topological states of matter challenge the paradigm of symmetry breaking, characterized by gapless boundary modes and protected by the topological property of the ground state. Recently, angle-resolved photoemission spectroscopy (ARPES) has revealed that semiconductors of Bi$_{2}$Se$_{3}$ and Bi$_{2}$Te$_{3}$ belong to such a class of materials. Here, we present undisputable evidence for the existence of gapless surface Dirac fermions from transport in Bi$_{2}$Te$_{3}$. We observe Sondheimer oscillation in magnetoresistance (MR). This oscillation originates from the quantization of motion due to the confinement of electrons within the surface layer. Based on Sondheimer's transport theory, we determine the thickness of the surface state from the oscillation data. In addition, we uncover the topological nature of the surface state, fitting consistently both the non-oscillatory part of MR and the Hall resistance. The side-jump contribution turns out to dominate around 1 T in Hall resistance while the Berry-curvature effect dominates in 3 T $\sim$ 4 T.

description: We study the non-equilibrium dynamics of cold atoms held in an optical lattice potential. The expansion of an initially confined atom cloud occurs in two phases: an initial quadratic expansion followed by a ballistic behaviour at long times. Accounting for this gives a good description of recent experimental results, and provides a robust method to extract the effective intersite tunneling from time-of-flight measurements.

description: We investigate the asymptotic behaviour of a class of self-interacting nearest neighbour random walks on the one-dimensional integer lattice which are pushed by a particular linear combination of their own local time on edges in the neighbourhood of their current position. We prove that in a range of the relevant parameter of the model such random walkers can be eventually confined to a finite interval of length depending on the parameter value. The phenomenon arises as a result of competing self-attracting and self-repelling effects where in the named parameter range the former wins.

description: The ALICE experiment consists of a central barrel in the pseudorapidity range -0.9 < $η$ < 0.9 and of additional detectors covering about 3 units of pseudorapidity on either side of the central barrel. Such a geometry allows the tagging of single and double gap events. The status of the analysis of such diffractive events in proton-proton collisions at $\sqrt{s}$ = 7 TeV is presented.

description: Magnetic properties of quark matter are discussed. The possibility of ferromagnetic transition is studied by using the one-gluon-exchange interaction. Magnetic susceptibility is evaluated within Landau Fermi liquid theory, and the important roles of the screening for the gluon propagation are elucidated. Static screening for the longitudinal gluons improves the infrared singularities, while the transverse gluons receive only dynamic screening. The latter property gives rise to a novel non-Fermi-liquid behaviour in the magnetic susceptibility. The critical density is estimated to be around the nuclear density and the Curie temperature several tens MeV. The spin density wave is also discussed at moderate densities, where chiral transition becomes important. Pseudoscalar condensate as well as scalar one takes a spatially non-uniform form in a chirally invariant way. Accordingly magnetization oscillates like spin density wave. These results should have some implications on compact star phenomena.

Operative delivery options in the second stage of labour : optimizing maternal and perinatal safety

description: Increased operative vaginal delivery, using obstetric forceps and/or vacuum, has been recommended in an effort to curb the rising rate of cesarean delivery. However, the comparative perinatal and maternal safety of operative vaginal delivery and cesarean delivery is not clear. This dissertation aimed to quantify rates of severe perinatal and maternal morbidity and mortality following operative vaginal delivery and cesarean delivery. The studies in this dissertation were based on information from Canadian national and provincial population-based health databases and included women who delivered a singleton term infant by operative vaginal or cesarean delivery between 2003 and 2014. Study sizes varied from 10,901 to 1,938,913. Logistic regression, propensity score analysis and ecological Poisson regression were used to estimate adjusted rate ratios (ARR) with 95% confidence intervals (CI). Midpelvic operative vaginal delivery was associated with an increased risk of severe perinatal morbidity/mortality compared with cesarean delivery, although this association varied based on instrument applied and indication for operative delivery. For example, among deliveries with dystocia, midpelvic operative vaginal delivery was associated with higher rates of severe perinatal morbidity/mortality compared with cesarean delivery (forceps ARR 2.11, 95% CI 1.46-3.07; vacuum ARR 2.17, 95% CI 1.49-3.15). Among deliveries with fetal distress, the risk of severe maternal morbidity/mortality was higher with midpelvic forceps and lower with midpelvic vacuum. However, rates of obstetric trauma were high following operative vaginal delivery, irrespective of instrument or indication. Rates of birth trauma and obstetric trauma were significantly increased after operative vaginal delivery at all pelvic stations. Further, the population (ecological) rate of operative vaginal delivery was positively associated with the rate of obstetric trauma and the rate of severe birth trauma: a one percent increase in the operative vaginal delivery rate resulted in over 700 additional cases of obstetric trauma per year among nulliparous women. Encouraging higher rates of operative vaginal delivery as a strategy to prevent cesarean delivery may result in higher rates of perinatal and maternal morbidity/mortality, especially birth trauma and obstetric trauma. The risks and benefits of both operative vaginal and cesarean delivery should be clearly communicated to women, ideally in the antepartum period.

description: We investigate magnetoresistance effects for transport across (Ga,Mn)As nanoislands, detached by nanoconstrictions from wider (Ga,Mn)As input leads. As in previous studies a huge magnetoresistance was found for nanoconstrictions in the tunnelling regime. For slightly wider junctions an enhanced anisotropic magnetoresistance effect was observed.

description: We investigate the interplay between the Kondo effect and randomness in MxTiSe2 (M = Co, Ni, and Fe) single crystals. Although the typical low-T upturn of resistivity implies the Kondo effect around the single-ion Kondo temperature \overline{T}_{K}, positive magnetoresistance linearly proportional to the magnetic field and the power-law scaling of magnetization suggest the forbidden coexistence between Kondo effect and time reversal symmetry breaking. This puzzling result is resolved by the Griffiths scenario - disorder-induced distribution of the Kondo temperature produces an effective Kondo temperature (\overline{T}_{K}) much lower than \overline{T}_{K}, allowing unscreened local moments above \overline{T}_{K} and resulting in non-Fermi liquid properties in MxTiSe2 below the percolation threshold (x

description: Brazil, which is hyperendemic for dengue virus (DENV), has had recent Zika (ZIKV) and (CHIKV) Chikungunya virus outbreaks. Since March 2016, CHIKV is the arbovirus infection most frequently diagnosed in Rio de Janeiro. In the analysis of 1835 syndromic patients, screened by real time RT-PCR, 56.4% of the cases were attributed to CHIKV, 29.6% to ZIKV, and 14.1% to DENV-4. Sequence analyses of CHIKV from sixteen samples revealed that the East-Central-South-African (ECSA) genotype of CHIKV has been circulating in Brazil since 2013 [95% bayesian credible interval (BCI): 03/2012-10/2013], almost a year before it was detected by arbovirus surveillance program. Brazilian cases are related to Central African Republic sequences from 1980’s. To the best of our knowledge, given the available sequence published here and elsewhere, the ECSA genotype was likely introduced to Rio de Janeiro early on 2014 (02/2014; BCI: 07/2013-08/2014) through a single event, after primary circulation in the Bahia state at the Northestern Brazil in the previous year. The observation that the ECSA genotype of CHIKV was circulating undetected underscores the need for improvements in molecular methods for viral surveillance.

description: We study a double quantum dot (DQD) coupled to a strongly biased quantum point contact (QPC), each embedded in independent electric circuits. For weak interdot tunneling we observe a finite current flowing through the Coulomb blockaded DQD in response to a strong bias on the QPC. The direction of the current through the DQD is determined by the relative detuning of the energy levels of the two quantum dots. The results are interpreted in terms of a quantum ratchet phenomenon in a DQD energized by a nearby QPC.

description: Fusion excitation functions are measured for the system $^6$Li+$^{28}$Si using the characteristic $γ$-ray method, encompassing both the sub-barrier and above barrier regions, viz., $E_{lab}$= 7-24 MeV. Two separate experiments were performed, one for the above barrier region ($E_{lab}$= 11-24 MeV) and another for the below barrier region ($E_{lab}$= 7-10 MeV). The results were compared with our previously measured fusion cross section for the $^7$Li+$^{28}$Si system. We observed enhancement of fusion cross section at sub-barrier regions for both $^6$Li and $^7$Li, but yield was substantially larger for $^6$Li. However, for well above barrier regions, similar type of suppression was identified for both the systems.

Spin blockade in lateral quantum dots - Negative differential conductance and spin spectroscopy

description: We report on spin blockade observed in several different lateral quantum dot systems. We observe the typical features of alternating position and amplitude of Coulomb peaks as a function of a magnetic field perpendicular to the sample surface. In a nonlinear regime strong negative differential conductance is observed with a striking regularity. This is not a universal behaviour. Instead we propose a complex interplay of spin blockade, electron interaction and relaxation. At strong tunnel coupling to the leads we use spin blockade as a spectroscopy tool to reveal the spin configuration in a Kondo regime with a pronounced chessboard pattern. By comparing measurements of different samples we find that Kondo effect and spin blockade can be combined in two different ways depending on the spin configuration of the dot. Thus the combination of both effects can be used to detect spin polarized filling of dot orbitals instead of regular filling.
