description: We obtain a non-linear generalization of the relativistic diffusion of particles with spin. We discuss diffusion equations whose non-linearity is a consequence of quantum statistics. We show that the assumptions of the relativistic invariance and an interpretation of the solution as a probability distribution substantially restrict the class of admissible non-linear diffusion equations. We consider relativistic invariant as well as covariant frame dependent diffusion equations with a drift. In the latter case we show that there can exist stationary solutions of the diffusion equation besides the equilibrium solution corresponding to the quantum or Tsallis distributions. We define the relative entropy as a function of the diffusion probability and prove that it is monotonically decreasing in time when the diffusion tends to the equilibrium. We discuss its relation to the thermodynamic behavior of diffusing particles.

description: We revisit the calculation of electroweak bremsstrahlung contributions to dark matter annihilation. Dark matter annihilation to leptons is necessarily accompanied by electroweak radiative corrections, in which a $W$ or $Z$ boson is also radiated. Significantly, while many dark matter models feature a helicity suppressed annihilation rate to fermions, bremsstrahlung process can remove this helicity suppression such that the branching ratios Br($\ell νW $), Br($\ell^+\ell^-Z$), and Br($\barννZ$) dominate over Br($\ell^+\ell^-$) and Br($\barνν$). We find this is most significant in the limit where the dark matter mass is nearly degenerate with the mass of the boson which mediates the annihilation process. Electroweak bremsstrahlung has important phenomenological consequences both for the magnitude of the total dark matter annihilation cross section and for the character of the astrophysical signals for indirect detection. Given that the $W$ and $Z$ gauge bosons decay dominantly via hadronic channels, it is impossible to produce final state leptons without accompanying protons, antiprotons, and gamma rays.

Dark shower investigations at Belle II for strongly interacting dark sectors
Creators: name: Tueschen, Tim
Publisher: name: University of British Columbia
Year: 2022

description: The so far unresolved question of the nature of dark matter has led to the development of a multitude of particle physics models that all meet current experimental and theoretical constraints, but differ greatly in the experimental signatures they predict. One idea that has been gaining popularity is that there could be a whole family of dark matter particles, forming a so called ’dark sector’ that interacts only very feebly with regular matter. In this thesis we investigate a hypothetical strongly interacting dark sector that confines at the GeV scale, which results in the production of a shower of dark sector mesons, including a long-lived neutral particle. This would result in a displaced vertex signature at e⁺e⁻ colliders such as the Belle II experiment. We provide a brief overview of current evidence for Dark Matter and existing constraints to motivate the choice of a QCD–like dark sector with a dark photon mediator, as well as a detailed description of the Belle II detector which has an excellent sensitivity to displaced vertex signatures. After briefly summarizing the model, we describe the general search strategy, examine possible sources of background, and test the feasibility of a zero-background analysis. We find that, while not all signatures can be investigated in the zero-background case, the model offers a large parameter space that can be well investigated at Belle II with currently available data.

description: A generalization of entropy to near-equilibrium phenomena is provided by the notion of a hydrodynamic entropy current. Recent advances in holography have lead to the formulation of fluid-gravity duality, a remarkable connection between the hydrodynamics of certain strongly coupled media and dynamics of higher dimensional black holes. This Letter introduces a correspondence between phenomenologically defined entropy currents in relativistic hydrodynamics and quasilocal horizons of near-equilibrium black objects in a dual gravitational description. A general formula is given, expressing the divergence of the entropy current in terms of geometric objects which appear naturally in the gravity dual geometry. The proposed definition is explicitly covariant with respect to boundary diffeomorphisms and reproduces known results when evaluated for the event horizon.

description: This work proposes a framework for large-scale stochastic derivative-free optimization (DFO) by introducing STARS, a trust-region method based on iterative minimization in random subspaces. This framework is both an algorithmic and theoretical extension of an algorithm for stochastic optimization with random models (STORM). Moreover, STARS achieves scalability by minimizing interpolation models that approximate the objective in low-dimensional affine subspaces, thus significantly reducing per-iteration costs in terms of function evaluations and yielding strong performance on large-scale stochastic DFO problems. The user-determined dimension of these subspaces, when the latter are defined, for example, by the columns of so-called Johnson--Lindenstrauss transforms, turns out to be independent of the dimension of the problem. For convergence purposes, both a particular quality of the subspace and the accuracies of random function estimates and models are required to hold with sufficiently high, but fixed, probabilities. Using martingale theory under the latter assumptions, an almost sure global convergence of STARS to a first-order stationary point is shown, and the expected number of iterations required to reach a desired first-order accuracy is proved to be similar to that of STORM and other stochastic DFO algorithms, up to constants.

description: Este estudo aborda a trajetória da inclusão da cultura afro-brasileira no Ensino Médio brasileiro duas décadasa pós a promulgação da Lei 10.639/2003. A legislação, que torna obrigatório o ensino da história e cultura afro-brasileira nas instituições de ensino, representa um marco na busca por uma educação mais inclusiva. A pesquisa vai além do aspecto legislativo, adentrando o terreno do racismo e suas implicações nas universidades brasileiras. O foco está nos impactos das ações afirmativas na estética e imagem corporal de negros, oferecendo uma perspectiva crítica sobre a interseção entre identidade racial e acesso ao conhecimento. A persistência das desigualdades raciais no mercado de trabalho, reflexo do histórico marcado pelo racismo estrutural, destaca a relevância deste estudo diante das discussões atuais sobre inclusão e diversidade. A discriminação racial é abordada como uma dimensão crítica, muitas vezes velada, que permeia a estrutura social brasileira. A compreensão do racismo é essencial para desvelar suas manifestações e enfrentar suas raízes históricas. A pesquisa busca lançar luz sobre a complexidade dessas questões, explorando os impactos da legislação, confrontando concepções populares de racismo e propondo uma análise do papel das ações afirmativas nas experiências educacionais e sociais dos afro-brasileiros nas universidades.

description: Undergraduate students are often assumed to be consumers of the material instructors bring to their attention. Rarely are they seen as producers of original research, other than in elite honors programmes or opt-in research opportunities such as university-based undergraduate research journals. Yet students new to a subject often have highly original responses to what they encounter. Though they may not yet be fully attuned to the contours of the scholarship, they are not limited by preexisting notions of what the defining questions of the field might be, nor are they as committed to the disciplinary boundaries that sometimes—intentionally or not—obscure or prevent promising lines of inquiry. We argue that recognizing students as emerging scholars capable of original, high quality work, and offering a structured assessment in the form of a peer reviewed class journal has the potential to transform how students they see themselves in relation to the discipline, supports the development of advanced research and writing skills, and encourages them to understand academic work as a collective rather than individual endeavor. This assessment also allows a wider range of students to access the benefits of participating in a comprehensive research activity that simulates the academic research process, rather than reserving such opportunities for those participating in elite programmes or opt-in research activities.

description: We give a new proof of the scattering below the ground state energy level for a class of nonlinear Schrödinger equations (NLS) with mass-energy intercritical competing nonlinearities. Specifically, the NLS has a focusing leading order nonlinearity with a defocusing perturbation. Our strategy combines interaction Morawetz estimates à la Dodson-Murphy and a new crucial bound for the Pohozaev functional of localized functions, which is essential to overcome the lack of a monotonicity condition. Furthermore, we give the rate of blow-up for symmetric solutions.

description: Lichen mapping is vital for caribou management plans and sustainable land conservation. Previous studies have used Random Forest, dense neural network, and convolutional neural network (CNN) models for mapping lichen coverage with remote sensing data. However, to date, it is not clear how these models rank in the performance of this task. In this study, these machine learning models were evaluated on their ability to predict lichen percent coverage in Sentinel-2 imagery covering Québec and Labrador, NL. The models were trained on 10-m resolution lichen coverage (%) maps created from 20 drone surveys collected in July 2019 and 2022. The maps were divided into quadrant blocks and then split into train, validation, and test datasets. The quadrant-blocking approach exposed the models to a variety of different landscapes and reduced spatial autocorrelation between the training sites. All three models performed similarly when evaluated on the test set. However, the dense neural network achieved a higher accuracy than the other two, with a reported Mean Absolute Error (MAE) of 5.2% and an R2 of 0.76. By comparison, the Random Forest model returned an MAE of 5.5% (R2: 0.74) and the CNN had an MAE of 5.3% (R2: 0.74). The models were also evaluated on their ability to predict lichen coverage (%) for larger quadrant blocks consisting of, on average, 400 Sentinel-2 pixels. The Random Forest and dense neural network had an R2 of 0.93, while the CNN had an R2 of 0.90. The MAE in this assessment for the dense neural network, Random Forest, and CNN were 2.1%, 2.3%, and 3.1% respectively. A regional lichen map was created using the dense neural network and a Sentinel-2 image mosaic. Model predictions have larger errors for land covers that the model was not exposed to in training, such as mines and deep lakes. While the dense neural network requires more computational effort to train than a Random Forest model, the 5.9% performance gain in the test pixel comparison and 9.1% performance gain in the quadrant block comparison renders it the most suitable for lichen mapping. This study represents progress toward determining the appropriate methodology for generating accurate lichen maps from satellite imagery for caribou conservation and sustainable land management.

description: Analyzing real data on international trade covering the time interval 1950-2000, we show that in each year over the analyzed period the network is a typical representative of the ensemble of maximally random weighted networks, whose directed connections (bilateral trade volumes) are only characterized by the product of the trading countries' GDPs. It means that time evolution of this network may be considered as a continuous sequence of equilibrium states, i.e. quasi-static process. This, in turn, allows one to apply the linear response theory to make (and also verify) simple predictions about the network. In particular, we show that bilateral trade fulfills fluctuation-response theorem, which states that the average relative change in import (export) between two countries is a sum of relative changes in their GDPs. Yearly changes in trade volumes prove that the theorem is valid.

description: We wanted to better understand if low-growing, perennial plants can be established as a ground cover in pipfruit orchards, as an alternative to a traditional 'weed spray strip'. The weed strip area often has low light, poor soil structure, and with long-term herbicide use can result in low organic matter levels, poor soil biology and unfavourable soil organisms. This trial looked at the establishment and impact of seven under-row 'cover crops' over a 9-month period.

description: Approximately 2.8 Myr before the present our planet was subjected to the debris of a supernova explosion. The terrestrial proxy for this event was the discovery of live atoms of 60Fe in a deep-sea ferromanganese crust. The signature for this supernova event should also reside in magnetite Fe3O4 microfossils produced by magnetotactic bacteria extant at the time of the Earth-supernova interaction, provided the bacteria preferentially uptake iron from fine-grained iron oxides and ferric hydroxides. Using estimates for the terrestrial supernova 60Fe flux, combined with our empirically derived microfossil concentrations in a deep-sea drill core, we deduce a conservative estimate of the ^{60}{Fe} fraction as 60Fe/Fe ~ 3.6 x 10^{-15}. This value sits comfortably within the sensitivity limit of present accelerator mass spectrometry capabilities. The implication is that a biogenic signature of this cosmic event is detectable in the Earth's fossil record.

Novel methods to assess three-dimensional tooth movement for the maxillary and mandibular dentitions
Creators: name: Alwafi, Abdulraheem Abdullah
Publisher: name: University of British Columbia
Year: 2022

description: Background Dental movement and position analyses are crucial for both clinical and research reasons. Previous studies have used X-rays, including cephalometric radiographs, CBCT, or the digital model superimposition, to assess dental movements and positions. In this dissertation, we develop novel three-dimensional (3D) methodologies using relatively stable landmarks for maxillary and mandibular dentition superimposition, dental movement measurements, and their applications in assessing the efficacy of clear aligner treatment. Methods This dissertation consists of a literature review (chapter 1), maxillary dentition (chapter 2), and mandibular dentition (chapter 3) methodologies for superimposition and dental tooth movement measurement and their application in assessing the efficacy of Invisalign treatment. Additionally, the construction of the long axes of different tooth parts in the anterior segment was demonstrated, compared, and discussed (chapter 4). Finally, chapter 5 includes a discussion, summary, overall strengths and limitations, clinical implications, future directions, and the study’s conclusion Results Our research projects developed novel methodologies to assess tooth movement in maxillary and mandibular dentitions, with high intra- and inter-examiner correlation coefficients (ICCs) agreement. Anteroposterior (AP) and buccolingual translational movements of all posterior teeth appeared to be accurate, with insignificant differences between ClinCheck® predicted and post-treatment digital models (P=1.000). Rotation and torque movements were less accurate with statistical significance (P=0.0012 and 0.00029, respectively). For the mandibular dentition, premolar rotation, incisor tipping, and molar AP movement showed a significant prediction difference at the 5% level. In terms of the long axis measurement, the long axis of the “Crown” appeared to be the furthest from the tooth composite long axis for the “Canine” when compared to the other anterior teeth (P= <0.0001). Conclusion The method developed for maxillary dentition tooth measurement is robust, reliable, user-friendly, and no radiation is involved. Achieving the predicted vertical, rotation, and torque tooth movements seems more challenging for specific maxillary posterior teeth during treatment with Invisalign. The method involving CBCT and dental superimposition to measure the 3D positional changes in the mandibular dentition is robust, reliable, and novel. Finally, determining the actual long axis of a tooth is challenging due to varying tooth morphology, differing imaging quality, and operator segmentation errors.

description: We introduce the (logarithmic) bipartite fidelity of a quantum system $A\cup B$ as the (logarithm of the) overlap between its ground-state wave function and the ground-state one would obtain if the interactions between two complementary subsystems $A$ and $B$ were switched off. We argue that it should typically satisfy an area law in dimension $d>1$. In the case of one-dimensional quantum critical points (QCP) we find that it admits a universal scaling form $\sim \ln \ell$, where $\ell$ is the typical size of the smaller subsystem. The prefactor is proportional to the central charge $c$ and depends on the geometry. We also argue that this quantity can be useful to locate quantum phase transitions, allows for a reliable determination of the central charge, and in general exhibits various properties that are similar to the entanglement entropy. Like the entanglement entropy, it contains subleading universal terms in the case of a 2D conformal QCP.

description: A new reactive force field to describe proton diffusion within the solid-oxide fuel cell material BaZrO3 has been derived. Using a quantum mechanical potential energy surface, the parameters of an interatomic potential model to describe hydroxyl groups within both pure and yttrium-doped BaZrO3 have been determined. Reactivity is then incorporated through the use of the empirical valence bond model. Molecular dynamics simulations (EVB-MD) have been performed to explore the diffusion of hydrogen using a stochastic thermostat and barostat whose equations are extended to the isostress-isothermal ensemble. In the low concentration limit, the presence of yttrium is found not to significantly influence the diffusivity of hydrogen, despite the proton having a longer residence time at oxygen adjacent to the dopant. This lack of influence is due to the fact that trapping occurs infrequently, even when the proton diffuses through octahedra adjacent to the dopant. The activation energy for diffusion is found to be 0.42 eV, in good agreement with experimental values, though the prefactor is slightly underestimated.

description: We report a detailed investigation of GdO$_{1-x}$F$_{x}$FeAs (x = 0, 0.07 and 0.14) samples by means of high-field/high-frequency electron spin resonance (HF-ESR) together with measurements of thermodynamic and transport properties. The parent GdOFeAs compound exhibits Fe long-range magnetic order below 128 K, whereas both doped samples do not show such order and are superconducting with T$_c$ = 20 K (x = 0.07) and T$_c$ = 45 K (x = 0.14). The Gd$^{3+}$ HF-ESR reveals an appreciable exchange coupling between Gd and Fe moments, through which the static magnetic order is clearly seen in the parent compound. Owing to this coupling, HF-ESR can probe sensitively the evolution of the magnetism in the FeAs planes upon F doping. It is found that in both superconducting samples, where the Fe long-range order is absent, there are short-range, static on the ESR time scale magnetic correlations between Fe spins. Their occurrence on a large doping scale may be indicative of the ground states' coexistence.

description: Surface temperature is a critical aspect for assessing the habitability of Earth-like planets. This temperature is determined by various factors such as albedo and greenhouse. The data collected from the JWST and upcoming space telescopes, such as the Habitable Worlds Observatory, would be crucial for constraining surface temperatures. In this study, we modeled the mean global surface temperature of Earth-like planets using for calibration the paleotemperatures of Earth in the last 750 million years. The model considers factors such as the distribution of different types of surface fractions (e.g., vegetation, ice, desert, ocean, and clouds), Bond albedo, and greenhouse effect. The model was fitted to theoretical and experimental data from paleotemperatures and satellite data using a Markov chain Monte Carlo (MCMC) analysis. Our results showed that changes in albedo due to variations in land-ocean ratios only led to a ± 2°C change from the current mean global temperature of 15°C. An Earth-like planet, with a similar stellar flux and atmospheric composition as Earth, should have a normalized greenhouse of 0.3 to 0.5 to support temperate conditions. We also defined a new planetary property, the “thermality,” which conveniently relates surface temperatures to stellar flux and other atmospheric properties. We found that the thermality of the Earth during the Phanerozoic was fairly constant, albeit the changes in albedo and greenhouse conditions. Our model can be used to constrain the mean global surface temperature of rocky planets, such as those in the TRAPPITS-1 system, based on JWST observations.

description: Introducing an infinite spatial lattice with box length a, a systematic expansion of the physical QCD Hamiltonian in λ= g^{-2/3} can be obtained. The free part is the sum of the Hamiltonians of the quantum mechanics of spatially constant fields for each box, and the interaction terms proportional to λ^n contain n discretised spatial derivatives connecting different boxes. As an example, the energy of the vacuum and the lowest scalar glueball is calculated up to order λ^2 for the case of SU(2) Yang-Mills theory.

Exploring explainable multilabel neural network as a psychometric tool for short-form test scoring and diagnostics : a study on College Major Preference Asessment
Creators: name: Hu, Shun-Fu
Publisher: name: University of British Columbia
Year: 2022

description: Motivated to integrate machine learning with quantitative methods in social science, this research consists of two studies, both using College Major Preference Assessment (CMPA) as data. Study-1 trained multilabel neural networks (MNNs), from machine learning, to predict the outcomes of the original CMPA, which consisted of two stages, with its short version, which consisted of only one of the stages. The findings showed the effectiveness of MNNs over the traditional simple sum scoring method: the MNN trained for accuracy had an accuracy of .94 (an improvement from .91 of simple sum), the one for recall had .93 recall (from .64), and for precision, .60 precision (from .34). The metrics, recall and precision, had been corrected to exclude chance guessing. Study-2 proposed a method for the intuitive diagnostics of the behaviour of trained MNNs by introducing Pratt’s measures, from quantitative methods in social science, to machine learning’s perturbation-based explainable AI methods. Two MNNs were chosen to demonstrate the explanatory method: The one trained to maximize the accuracy of CMPA short-version scoring, and the other maximizing the adjusted recall of it. To understand a single MNN, 5000 trials were conducted. In each trial, a new MNN with the same settings as the one to be studied was trained on a random subset of 50% of the originally used input variables. Then, the relative importance of each input variable was obtained by calculating the Pratt’s measures for a linear regression where the independent variables were the inclusion statuses of all input variables, and the dependent variable was the MNN’s performance on a major. The visualized patterns of the Pratt’s measures (the results) were shown diagnostic of the strength of validity evidence for using the two MNNs for the prediction of respondents’ preferences for certain college major assessed by CMPA, and the lack thereof, for other majors. The implications were discussed in the context of existing pioneering fields integrating machine learning with social science research, including computational psychometrics, educational data mining and psychoinformatics. Limitations and future research were addressed.

description: We present a new methodology to determine the expansion history of the Universe analyzing the spectral properties of early type galaxies (ETG). We found that for these galaxies the 4000Åbreak is a spectral feature that correlates with the relative ages of ETGs. In this paper we describe the method, explore its robustness using theoretical synthetic stellar population models, and apply it using a SDSS sample of $\sim$14 000 ETGs. Our motivation to look for a new technique has been to minimise the dependence of the cosmic chronometer method on systematic errors. In particular, as a test of our method, we derive the value of the Hubble constant $H_0 = 72.6 \pm 2.8$ (stat) $\pm2.3$ (syst) (68% confidence), which is not only fully compatible with the value derived from the Hubble key project, but also with a comparable error budget. Using the SDSS, we also derive, assuming w=constant, a value for the dark energy equation of state parameter $w = -1 \pm 0.2$ (stat) $\pm0.3$ (syst). Given the fact that the SDSS ETG sample only reaches $z \sim 0.3$, this result shows the potential of the method. In future papers we will present results using the high-redshift universe, to yield a determination of H(z) up to $z \sim 1$.

description: We give an alternative description of the physical content of general relativity that does not require a Lorentz invariant spacetime. Instead, we find that gravity admits a dual description in terms of a theory where local size is irrelevant. The dual theory is invariant under foliation preserving 3-diffeomorphisms and 3D conformal transformations that preserve the 3-volume (for the spatially compact case). Locally, this symmetry is identical to that of Horava-Lifshitz gravity in the high energy limit but our theory is equivalent to Einstein gravity. Specifically, we find that the solutions of general relativity, in a gauge where the spatial hypersurfaces have constant mean extrinsic curvature, can be mapped to solutions of a particular gauge fixing of the dual theory. Moreover, this duality is not accidental. We provide a general geometric picture for our procedure that allows us to trade foliation invariance for conformal invariance. The dual theory provides a new proposal for the theory space of quantum gravity.

Mixed higher-order topology: boundary non-Hermitian skin effect induced by a Floquet bulk

description: We show that anomalous Floquet topological insulators generate intrinsic, non-Hermitian topology on their boundary. As a consequence, removing a boundary hopping from the time-evolution operator stops the propagation of chiral edge modes, leading to a non-Hermitian skin effect. This does not occur in Floquet Chern insulators, however, in which boundary modes continue propagating. The non-Hermitian skin effect on the boundary is a consequence of the nontrivial topology of the bulk Floquet operator, which we show by designing a real-space topological invariant. Our work introduces a form of `mixed' higher-order topology, providing a bridge between research on periodically-driven systems and the study of non-Hermiticity. It suggests that periodic driving, which has already been demonstrated in a wide range of experiments, may be used to generate non-Hermitian skin effects.

description: We construct Mori Dream Spaces as fine moduli spaces of representations of bound quivers, thereby extending results of Craw--Smith \cite{CrawSmith} beyond the toric case. Any collection of effective line bundles $\mathscr{L}=(\mathscr{O}_X, L_1,..., L_r)$ on a Mori Dream Space $X$ defines a bound quiver of sections and a map from $X$ to a toric quiver variety $|\mathscr{L}|$ called the multigraded linear series. We provide necessary and sufficient conditions for this map to be a closed immersion and, under additional assumptions on $\mathscr{L}$, the image realises $X$ as the fine moduli space of $\vartheta$-stable representations of the bound quiver. As an application, we show how to reconstruct del Pezzo surfaces from a full, strongly exceptional collection of line bundles.
