description: We describe a systematic method to construct models of Chern insulators whose Berry curvature and the quantum volume form coincide and are flat over the Brillouin zone; such models are known to be suitable for hosting fractional Chern insulators. The bands of Chern insulator models where the Berry curvature and the quantum volume form coincide, and are nowhere vanishing, are known to induce the structure of a Kähler manifold in momentum space, and thus we are naturally led to define Kähler bands to be Chern bands satisfying such properties. We show how to construct a geometrically flat Kähler band, with Chern number equal to minus the total number of bands in the system, using the idea of Kähler quantization and properties of Bergman kernel asymptotics. We show that, with our construction, the geometrical properties become flatter as the total number of bands in the system is increased; we also show the no-go theorem that it is not possible to construct geometrically perfectly flat Kähler bands with a finite number of bands. We give an explicit realization of this construction in terms of theta functions and numerically confirm how the constructed Kähler bands become geometrically flat as we increase the number of bands. We also show the effect of truncating hoppings at a finite length, which will generally result in deviation from a perfect Kähler band but does not seem to seriously affect the flatness of the geometrical properties.

Simulating starspot activity jitter for spectral types F--M: realistic estimates for a representative sample of known exoplanet hosts

description: Dark spots on the surface of active stars produce changes in the shapes of the spectral lines that mimic spurious Doppler shifts, compromising the detection of small planets by means of the radial velocity (RV) technique. Modelling the spot-driven RV variability (known as ``jitter'') and how it affects the RV data sets is therefore crucial to design efficient activity-filtering techniques and inform observing strategies. Here, we characterise starspots and simulate the radial velocity curves induced by them to determine typical jitter amplitudes for a representative sample of 15 known host stars spanning between F and M spectral type. We collect information on the $\log R'_{\mathrm{HK}}$ activity index from the literature for 205 stars and, due to a lack of data in the temperature range 4000-4500 K, we measure it for ten stars using archival data. Additional stellar parameters required for the simulations are collected from the literature or constrained by observational data, in order to derive realistic estimates. Our results can be used as reference to determine typical peak-to-peak spot-induced RV jitter in the visible domain that can be expected when targeting host stars with different properties.

description: We present an end-to-end deep network model that performs meeting diarization from single-channel audio recordings. End-to-end diarization models have the advantage of handling speaker overlap and enabling straightforward handling of discriminative training, unlike traditional clustering-based diarization methods. The proposed system is designed to handle meetings with unknown numbers of speakers, using variable-number permutation-invariant cross-entropy based loss functions. We introduce several components that appear to help with diarization performance, including a local convolutional network followed by a global self-attention module, multi-task transfer learning using a speaker identification component, and a sequential approach where the model is refined with a second stage. These are trained and validated on simulated meeting data based on LibriSpeech and LibriTTS datasets; final evaluations are done using LibriCSS, which consists of simulated meetings recorded using real acoustics via loudspeaker playback. The proposed model performs better than previously proposed end-to-end diarization models on these data.

description: We explore the possibility of discovering the mirror baryons and electrons of the Mirror Twin Higgs model in direct detection experiments, in a scenario in which these particles constitute a subcomponent of the observed DM. We consider a framework in which the mirror fermions are sub-nano-charged, as a consequence of kinetic mixing between the photon and its mirror counterpart. We consider both nuclear recoil and electron recoil experiments. The event rates depend on the fraction of mirror DM that is ionized, and also on its distribution in the galaxy. Since mirror DM is dissipative, at the location of the Earth it may be in the form of a halo or may have collapsed into a disk, depending on the cooling rate. For a given mirror DM abundance we determine the expected event rates in direct detection experiments for the limiting cases of an ionized halo, an ionized disk, an atomic halo and an atomic disk. We find that by taking advantage of the complementarity of the different experiments, it may be possible to establish not just the multi-component nature of mirror dark matter, but also its distribution in the galaxy. In addition, a study of the recoil energies may be able to determine the masses and charges of the constituents of the mirror sector. By showing that the mass and charge of mirror helium are integer multiples of those of mirror hydrogen, these experiments have the potential to distinguish the mirror nature of the theory. We also carefully consider mirror plasma screening effects, showing that the capture of mirror dark matter particles in the Earth has at most a modest effect on direct detection signals.

Durante o Neoproterozoico, a biosfera é caracterizada pelo registro das revoluções biológicas (e.g. aquisição de partes duras e surgimento dos metazoários) associadas a grandes mudanças climáticas e químicas nos oceanos (e.g. glaciações, depósitos ferríferos), porém, pouco se sabe a respeito das reais implicações destes eventos. Este projeto faz parte do Projeto temático FAPESP (2016/06114-6; 2017/22099-0), intitulado "The Neoproterozoic Earth System and the rise of biological complexity". Os principais resultados derivados desta pesquisa dividem-se em quatro conjuntos: (i) levantamento e petrografia de 10 seções estratigráficas inéditas na Faixa Paraguai Sul, MS, sendo sete na região de Corumbá (Formação Urucum, Grupo Jacadigo) e três na Serra da Bodoquena (Formação Bocaina, Grupo Corumbá); (ii) descoberta e descrição dos primeiros eucariontes unicelulares heterotróficos biomineralizadores de sílica (“Vase-shaped microfossils" – VSMs); (iii) caracterização tafonômica e taxonômica de seis novas espécies de VSMs e duas novas ocorrências de acritarcos no Neoproterozoico; e (iv) reconhecimento de novos intervalos bioestratigráficos no limite Criogeniano-Cambriano. O uso de diversas técnicas (e.g. espectroscopia Raman e confocal, MEV, EDS, micro-ct, catodoluminescência) tem fornecido resultados que preenchem lacunas sobre a química dos oceanos, paleogeografia e evolução dos eucariontes na Faixa Paraguai Sul entre o Criogeniano e o Cambriano, com implicações para paleontologia do Brasil e do mundo.

description: The chemical potential $μ$ of a many-body system is valuable since it carries fingerprints of phase changes. Here, we summarize results for $μ$ for a thre e-dimensional electron liquid in terms of average kinetic and potential energie s per particle. The difference between $μ$ and the energy per particle is fou nd to be exactly the electrostatic potential step at the surface. We also prese nt calculations for an integrable one-dimensional many-body system with delta f unction interactions, exhibiting a BCS-BEC crossover. It is shown that in the B CS regime the chemical potential can be expressed solely in terms of the ground -state energy per particle. A brief discussion is also included of the strong c oupling BEC limit.

Pupils’ prior beliefs about bacteria and science processes : their interplay in school science laboratory work
Creators: name: Maxted, Margaret Anne
Publisher: name: University of British Columbia
Year: 2010

description: School science laboratory tasks involve the use of conceptual frameworks and scientific processes. Shayer (1978) has criticized Nuffield science curricula for their alleged mis-match with the average pupil's cognitive ability to perform laboratory tasks involving scientific processes such as controlling variables. Researchers interested in pupils' conceptual frameworks view the context of the experiment as a significant influence on the pupils' understanding of the experiment and it is thought that prior beliefs may interfere with the pupils' ability to control variables. This study examines qualitatively the interplay between the pupils' substantive beliefs about bacteria, prior to instruction, and their influence on understanding of the scientific processes in a laboratory experiment about bacteria. Thirty-one pupils in the second year (12/13 year olds) of a secondary school in England were interviewed in order to elicit their substantive beliefs about bacteria. These pupils then followed a series of two experiments taken from Nuffield Combined Science coursework. Nine pupils were interviewed after each experiment to ascertain their understanding of the task they had undertaken. Two groups of pupils for each experiment were audio-taped while they set up the experiment and their discussion of the questions about the task were recorded. Written work was also examined to cross validate views held by other members of the class. It was found that pupils whose prior beliefs included concepts of bacterial life connected with reproduction were able to understand the role of the control in the experiment. Pupils' concepts of the growth of bacteria were found to be varied. Pupils who held less scientifically based concepts of bacterial growth were unable to explain the use of the control plate. Some pupils who had more sophisticated prior conceptions of growth failed to use them in explanations about the control plate and showed signs that their beliefs concerning the design of the equipment interfered with their ability to understand the role of the control plate. Prior beliefs were found to be a major influence on the pupils' understanding of the experiment. Teachers are recommended to investigate pupils' prior beliefs of the concepts being taught and encourage pupils to reflect upon the activity engaged in by the pupil during school science laboratory tasks.

description: An axion rotating in field space can produce dark photons in the early universe via tachyonic instability. This explosive particle production creates a background of stochastic gravitational waves that may be visible at pulsar timing arrays or other gravitational wave detectors. This scenario provides a novel history for dark photon dark matter. The dark photons may be warm at a level detectable in future 21-cm line surveys. For a consistent cosmology, the radial direction of the complex field containing the axion must be thermalized. We explore a concrete thermalization mechanism in detail and also demonstrate how this setup can be responsible for the generation of the observed baryon asymmetry.

description: In this paper, we present a study aimed at understanding whether the embodiment and humanlikeness of an artificial agent can affect people's spontaneous and instructed mimicry of its facial expressions. The study followed a mixed experimental design and revolved around an emotion recognition task. Participants were randomly assigned to one level of humanlikeness (between-subject variable: humanlike, characterlike, or morph facial texture of the artificial agents) and observed the facial expressions displayed by a human (control) and three artificial agents differing in embodiment (within-subject variable: video-recorded robot, physical robot, and virtual agent). To study both spontaneous and instructed facial mimicry, we divided the experimental sessions into two phases. In the first phase, we asked participants to observe and recognize the emotions displayed by the agents. In the second phase, we asked them to look at the agents' facial expressions, replicate their dynamics as closely as possible, and then identify the observed emotions. In both cases, we assessed participants' facial expressions with an automated Action Unit (AU) intensity detector. Contrary to our hypotheses, our results disclose that the agent that was perceived as the least uncanny, and most anthropomorphic, likable, and co-present, was the one spontaneously mimicked the least. Moreover, they show that instructed facial mimicry negatively predicts spontaneous facial mimicry. Further exploratory analyses revealed that spontaneous facial mimicry appeared when participants were less certain of the emotion they recognized. Hence, we postulate that an emotion recognition goal can flip the social value of facial mimicry as it transforms a likable artificial agent into a distractor.

Becoming a Flexible Teacher through Critical Reflective Journaling
by
Marianne Young, Master of Science
Utah State University, 2021
Major Professor: Dr. Jessica Rivera-Mueller
Department: English
Because reflection through journaling allows teachers to critically analyze their teaching paradigms, this portfolio argues that veteran teachers should take time to critically reflect upon their teaching through the practice of journaling. The portfolio contains three sections: a philosophy statement on the importance of reflection, an essay created to share findings from the author’s practice of critically reflecting through journaling, and a tool to support teachers’ critical reflection through journaling.  Together, these pieces argue for the importance of reflection and demonstrate how journaling can help veteran teachers uncover key themes that lead to becoming more flexible and adaptable in the classroom.

description: Utilizing the Atacama Large Millimeter/submillimeter Array (ALMA), we present CS line maps in five rotational lines ($J_{\rm u}=7, 5, 4, 3, 2$) toward the circumnuclear disk (CND) and streamers of the Galactic Center. Our primary goal is to resolve the compact structures within the CND and the streamers, in order to understand the stability conditions of molecular cores in the vicinity of the supermassive black hole (SMBH) Sgr A*. Our data provide the first homogeneous high-resolution ($1.3'' = 0.05$ pc) observations aiming at resolving density and temperature structures. The CS clouds have sizes of $0.05-0.2$ pc with a broad range of velocity dispersion ($σ_{\rm FWHM}=5-40$ km s$^{-1}$). The CS clouds are a mixture of warm ($T_{\rm k}\ge 50-500$ K, n$_{\rm H_2}$=$10^{3-5}$ cm$^{-3}$) and cold gas ($T_{\rm k}\le 50$ K, n$_{\rm H_2}$=$10^{6-8}$ cm$^{-3}$). A stability analysis based on the unmagnetized virial theorem including tidal force shows that $84^{+16}_{-37}$ % of the total gas mass is tidally stable, which accounts for the majority of gas mass. Turbulence dominates the internal energy and thereby sets the threshold densities $10-100$ times higher than the tidal limit at distance $\ge 1.5$ pc to Sgr A*, and therefore, inhibits the clouds from collapsing to form stars near the SMBH. However, within the central $1.5$ pc, the tidal force overrides turbulence and the threshold densities for a gravitational collapse quickly grow to $\ge 10^{8}$ cm$^{-3}$.

description: We propose a novel source of gravitational wave emission: the inspirals of compact fragments inside primordial supermassive stars (SMSs). Such systems are thought to be an essential channel in the as-yet little understood formation of supermassive black holes (SMBHs). One model suggests that high accretion rates of $0.1$-1 M$_\odot$/yr attainable in atomically-cooled primordial halos can lead to the formation of a nuclear-burning SMS. This will ultimately undergo collapse through a relativistic instability, leaving a massive BH remnant. Recent simulations suggest that supermassive stars rarely form in isolation, and that companion stars and even black holes formed may be captured/accreted and inspiral to the SMS core due to gas dynamical friction. Here, we explore the GW emission produced from such inspirals, which could probe the formation and evolution of SMS and seeds of the first supermassive black holes. We use a semi-analytic gas-dynamical friction model of the inspirals in the SMS to characterize their properties. We find such sources could potentially be observable by upcoming space-born GW-detectors at their formation redshifts with the benefit of gravitational lensing. Mergers within closely-related quasi-stars may produce a much stronger signal, though disambiguating such events from other high-z events may prove challenging.

description: The exoplanetary system of HR 8799 is one of the rare systems in which multiple planets have been directly imaged. Its architecture is strikingly similar to that of the Solar System, with the four imaged giant planets surrounding a warm dust belt analogous to the Asteroid Belt, and themselves being surrounded by a cold dust belt analogue to the Kuiper Belt. Previous observations of this cold belt with ALMA in Band 6 (1.3 mm) revealed its inner edge, but analyses of the data differ on its precise location. It was therefore unclear whether the outermost planet HR 8799 b was dynamically sculpting it or not. We present here new ALMA observations of this debris disk in Band 7 (340 GHz, 880 micron). These are the most detailed observations of this disk obtained so far, with a resolution of 1" (40 au) and sensitivity of $9.8\,μ\mathrm{Jy\,beam^{-1}}$, which allowed us to recover the disk structure with high confidence. In order to constrain the disk morphology, we fit its emission using radiative transfer models combined with a MCMC procedure. We find that this disk cannot be adequately represented by a single power law with sharp edges. It exhibits a smoothly rising inner edge and smoothly falling outer edge, with a peak in between, as expected from a disk that contains a high eccentricity component, hence confirming previous findings. Whether this excited population and inner edge shape stem from the presence of an additional planet remains, however, an open question.

description: We consider leading order quantum corrections to the geometry of large AdS black holes in a spherical reduction of four-dimensional Einstein gravity with negative cosmological constant. The Hawking temperature grows without bound with increasing black hole mass, yet the semiclassical back-reaction on the geometry is relatively mild, indicating that observers in free fall outside a large AdS black hole never see thermal radiation at the Hawking temperature. The positive specific heat of large AdS black holes is a statement about the dual gauge theory rather than an observable property on the gravity side. Implications for string thermodynamics with an AdS infrared regulator are briefly discussed.

description: Quantum metrology promises greater sensitivity for optical phase measurements than could ever be achieved classically. Here we present a theory of the phase sensitivity for the general case where the detection probability is given by an $N$ photon interference fringe. We find that the phase sensitivity has a complex dependence on both the intrinsic efficiency of detection $η$ and the interference fringe visibility $V$. Most importantly, the phase that gives maximum phase sensitivity is in general not the same as the phase at which the slope of the interference fringe is a maximum, as has previously been assumed. We determine the parameter range where quantum enhanced sensitivity can be achieved. In order to illustrate these theoretical results, we perform a four photon experiment with $η=3/4$ and $V=82\pm6$% (an extension of our previous work [Science \textbf{316}, 726 (2007)]) and find a phase sensitivity 1.3 times greater than the standard quantum limit at a phase different to that which gives maximum slope of the interference fringe.

description: Resolved sideband cooling is a standard technique for cooling trapped ions below the Doppler limit to near their motional ground state. Yet, the most common methods for sideband cooling implicitly rely on low Doppler-cooled temperatures and tightly confined ions, and they cannot be optimized for different experimental conditions. Here we introduce a framework which calculates the fastest possible pulsed sideband cooling sequence for a given number of pulses and set of experimental parameters, and we verify its improvement compared to traditional methods using a trapped $^{171}$Yb$^+$ ion. After extensive cooling, we find that the ion motional distribution is distinctly non-thermal and thus not amenable to standard thermometry techniques. We therefore develop and experimentally validate an improved method to measure ion temperatures after sideband cooling. These techniques will enable more efficient cooling and thermometry within trapped-ion systems, especially those with high initial temperatures or spatially-extended ion wavepackets.

description: We study sequential scattering in superradiance from a Bose-Einstein condensate pumped by a two-frequency laser beam. We find that the distribution of atomic side modes presents highly different patterns for various frequency difference between the two pump components. A novel distribution is observed, with a frequency difference of eight times the recoil frequency. These observations reveal that the frequency overlap between the end-fire modes related to different side modes plays an essential role in the dynamics of sequential superradiant scattering. The numerical results from a semiclassical model qualitatively agree with our observations.

description: High-dynamic range imaging from space in the visible, aiming in particular at the detection of terrestrial exoplanets, necessitates not only the use of a coronagraph, but also of adaptive optics to correct optical defects in real time. Indeed, these defects scatter light and give birth to speckles in the image plane. Speckles can be cancelled by driving a deformable mirror to measure and compensate wavefront aberrations. In a first approach, targeted speckle nulling, speckles are cancelled iteratively by starting with the brightest ones. This first method has demonstrated a contrast better than 1e9 in laboratory. In a second approach, zonal speckle nulling, the total energy of speckles is minimized in a given zone of the image plane. This second method has the advantage to tackle simultaneously all speckles from the targeted zone, but it still needs better experimental demonstration.

description: Galaxies inhabit a wide range of environments and therefore are affected by different physical mechanisms. Spatially resolved maps combined with the knowledge of the hosting environment are very powerful to classify galaxies by physical process. In the context of the GAs Stripping Phenomena in galaxies (GASP), we present a study of 27 non-cluster galaxies: 24 of them were selected for showing asymmetries and disturbances in the optical morphology, suggestive of gas stripping, three of them are passive galaxies and were included to characterize the final stages of galaxy evolution. We therefore provide a panorama of the different processes taking place in low-density environments. The analysis of VLT/MUSE data allows us to separate galaxies into the following categories: Galaxy-galaxy interactions (2 galaxies), mergers (6), ram pressure stripping (4), cosmic web stripping (2), cosmic web enhancement (5), gas accretion (3), starvation (3). In one galaxy we identify the combination of merger and ram pressure stripping. Only 6/27 of these galaxies have just a tentative classification. We then investigate where these galaxies are located on scaling relations determined for a sample of undisturbed galaxies. Our analysis shows the successes and limitations of a visual optical selection in identifying the processes that deplete galaxies of their gas content and probes the power of IFU data in pinning down the acting mechanism.

description: Anomaly detection techniques are growing in importance at the Large Hadron Collider (LHC), motivated by the increasing need to search for new physics in a model-agnostic way. In this work, we provide a detailed comparative study between a well-studied unsupervised method called the autoencoder (AE) and a weakly-supervised approach based on the Classification Without Labels (CWoLa) technique. We examine the ability of the two methods to identify a new physics signal at different cross sections in a fully hadronic resonance search. By construction, the AE classification performance is independent of the amount of injected signal. In contrast, the CWoLa performance improves with increasing signal abundance. When integrating these approaches with a complete background estimate, we find that the two methods have complementary sensitivity. In particular, CWoLa is effective at finding diverse and moderately rare signals while the AE can provide sensitivity to very rare signals, but only with certain topologies. We therefore demonstrate that both techniques are complementary and can be used together for anomaly detection at the LHC.

Donoso, a narrative cycle of fiction
Creators: name: Shamash, Eve Marie
Publisher: name: University of British Columbia
Year: 2010

description: This thesis studies the first four novels ( Coronacion , Este domingo, EJ. lugar sin limites , EI obsceno pajaro de la noche ) of the Chilean author Jose/ Donoso, born in 1924. The thesis proposes that these four novels form a coherent narrative cycle of fiction which is linked together by a common theme of destruction. The thesis demonstrates that the theme of destruction is developed in each successive novel with increasing emphasis on fantasy, on the grotesque and on the irrational. Parallel to this increasing emphasis on the unreal, this study outlines Donoso's increased experimentation with innovative literary techniques as the novels move towards a total rejection of traditional realism and its attributes of verisimilitude. In terms of narrative technique, this study points out key literary influences on Donoso's writing: Henry James and William Faulkner are considered to be the most significant. This study proposes that the archetypal structure of the novels from Coronacion to El obsceno pajaro de la noche is vital to the thematic development in each novel and from one novel to the next, in a cyclical context. The thesis uses the analysis of the archetypal structure to demonstrate how the theme of destruction is organized and orchestrated. This study also outlines the main biographical, existential and psychoanalytical elements which are integrated into the broader archetypal structure. The archetypal analysis largely follows the methodological approach of Northrop Frye. This analysis outlines Donoso's restating and reshaping of recurrent archetypes which are the basis of the biblical myths that bourgeois society has cultivated and which Donoso presents in a demonic inversion. This thesis concludes that the Bible, as myth, provides a synthesizing archetypal structure to Donoso's narrative cycle of fiction and proposes that the mythical patterns in the novel are mainly organized by apocalyptic imagery and demonic parody, an inversion of Christian beliefs. The study of Donoso's first four novels as a mytho-poetic presentation of the process of destruction and of the eternal fall demonstrates the aesthetic unity, beauty and the richness of significance which make Donoso a great writer.
