description: Topic models have been the prominent tools for automatic topic discovery from text corpora. Despite their effectiveness, topic models suffer from several limitations including the inability of modeling word ordering information in documents, the difficulty of incorporating external linguistic knowledge, and the lack of both accurate and efficient inference methods for approximating the intractable posterior. Recently, pretrained language models (PLMs) have brought astonishing performance improvements to a wide variety of tasks due to their superior representations of text. Interestingly, there have not been standard approaches to deploy PLMs for topic discovery as better alternatives to topic models. In this paper, we begin by analyzing the challenges of using PLM representations for topic discovery, and then propose a joint latent space learning and clustering framework built upon PLM embeddings. In the latent space, topic-word and document-topic distributions are jointly modeled so that the discovered topics can be interpreted by coherent and distinctive terms and meanwhile serve as meaningful summaries of the documents. Our model effectively leverages the strong representation power and superb linguistic features brought by PLMs for topic discovery, and is conceptually simpler than topic models. On two benchmark datasets in different domains, our model generates significantly more coherent and diverse topics than strong topic models, and offers better topic-wise document representations, based on both automatic and human evaluations.

description: For an open-boundary spin chain with anisotropic Heisenberg (XXZ) interactions, we present states in which a connected block near the edge is polarized oppositely to the rest of the chain. We show that such blocks can be `locked' to the edge of the spin chain, and that there is a hierarchy of edge-locking effects at various orders of the anisotropy. The phenomenon enables dramatic control of quantum state transmission: the locked block can be freed by flipping a single spin or a few spins.

description: This article aims at discussing the state responsibility concerning educational rights as a framework to problematize issues of social justice on two national contexts of South Europe with an expressive vulnerable adult population concerning qualifications. We supported our analysis of national ALE public policies on Tomaševski (2001) theoretical and analytical framework that focuses on the accomplishment of the right of education by national states. Research goals are to analyse and compare ALE as a human right in the context of both states obligations, and to qualitatively evaluate selected national policies as fostering participation and social justice. This article responds to the follow question: what are the national policies that contribute to express ALE as a human right and why? It presents the scenarios obtained through Tomaševski model and point out to interesting differences between Portuguese and Italian cases.

Automating computed tomography diagnostic image quality control using deep learning
Creators: name: Gupta, Anubhav
Publisher: name: University of British Columbia
Year: 2024

description: Medical imaging quality control is traditionally done through routine manual testing, which is time-consuming, error-prone, and costly. There has been limited exploration of automating this quality control process using deep learning techniques. Several factors contribute to this gap in research, including 1) the need for a specialized labelled dataset to evaluate this problem, 2) the scarcity of labelled medical imaging data for training state-of-the-art deep learning models capable of robust generalization on medical imaging classification tasks, and 3) the absence of a dedicated deep learning backbone pre-trained on medical imaging data capable of robust generalization for various medical image analysis tasks. This thesis first presents a study that evaluates state-of-the-art deep convolutional neural network models to automate the quality control process for medical images. By harnessing transfer learning, the goal is to enhance the availability and effectiveness of medical image diagnostic scanners for applications in patient diagnosis, treatment, research, and development. We evaluate the performance of 5 different models wherein InceptionResNetV2 achieves the best accuracy of 99%. However, when these models are tested on out-of-domain datasets, the results show a crucial need for more robust models capable of automating quality control within different healthcare facilities. In the second part of the thesis, we employ a self-supervised approach to pre-train a specialized backbone, referred to as MedMAE, using a diverse dataset comprising over two million publicly available medical images. Our results demonstrate that MedMAE effectively captures the unique characteristics of medical images, leading to improved accuracy in downstream medical imaging tasks and even on out-of-domain datasets. This innovative approach holds promise for enhancing the utility and efficiency of medical image analysis, bridging the gap caused by the scarcity of labelled data in the healthcare domain. Furthermore, to evaluate the effectiveness of MedMAE, we employ a Virtual Reality tool for precise manual annotation of discrepancies between the original medical images and the reconstructions produced by MedMAE.

description: The development of Imaging Atmospheric Cherenkov Telescopes (IACTs) unveiled the sky in the teraelectronvolt regime, initiating the so-called "TeV revolution", at the beginning of the new millennium. This revolution was also facilitated by the implementation and adaptation of statistical tools for analyzing the shower images collected by these telescopes and inferring the properties of the astrophysical sources that produce such events. Image reconstruction techniques, background discrimination, and signal-detection analyses are just a few of the pioneering studies applied in recent decades in the analysis of IACTs data. This (succinct) review has the intent of summarizing the most common statistical tools that are used for analyzing data collected with IACTs, focusing on their application in the full analysis chain, including references to existing literature for a deeper examination.

description: What is an adult? According to Arendt an adult is a person who assumes the task of caring for the world, who takes responsibility – in the sight of younger generations – for what happens, how the world is. In global societies, where the actions of individual agents reverberate across national boundaries, does the traditional construct of political responsibility still hold water? Given the historical-cultural changes that the concept has undergone, we ask: what notion do our younger generations have of responsibility and how do they put it into practice? Is it important to them? To explore the perspectives of young people, we administered 167 questionnaires to students on the Primary Teaching degree course at the University of Verona. The experiences identified by the students as examples of responsibility relate, primarily, to their daily lives and their immediate context, while the public sphere, in a political sense, is almost entirely absent.

description: This paper is concerned with the stability analysis of the recurrent neural networks (RNNs) by means of the integral quadratic constraint (IQC) framework. The rectified linear unit (ReLU) is typically employed as the activation function of the RNN, and the ReLU has specific nonnegativity properties regarding its input and output signals. Therefore, it is effective if we can derive IQC-based stability conditions with multipliers taking care of such nonnegativity properties. However, such nonnegativity (linear) properties are hardly captured by the existing multipliers defined on the positive semidefinite cone. To get around this difficulty, we loosen the standard positive semidefinite cone to the copositive cone, and employ copositive multipliers to capture the nonnegativity properties. We show that, within the framework of the IQC, we can employ copositive multipliers (or their inner approximation) together with existing multipliers such as Zames-Falb multipliers and polytopic bounding multipliers, and this directly enables us to ensure that the introduction of the copositive multipliers leads to better (no more conservative) results. We finally illustrate the effectiveness of the IQC-based stability conditions with the copositive multipliers by numerical examples.

description: The affect of demographic stochasticity of a system of globally coupled chaotic maps is considered. A two-step model is studied, where the intra-patch chaotic dynamics is followed by a migration step that coupled all patches; the equilibrium number of agents on each site, $N$, controls the strength of the discreteness-induced fluctuations. For small $N$ (large fluctuations) a period-doubling cascade appears as the coupling (migration) increases. As $N$ grows an extremely slow dynamic emerges, leading to a flow along a one-dimensional family of almost period 2 solutions. This manifold become a true solutions in the deterministic limit. The degeneracy between different attractors that characterizes the clustering phase of the deterministic system is thus the $N \to \infty$ limit of the slow dynamics manifold.

description: We report the discovery of the second compact elliptical (cE) galaxy SDSSJ150634.27+013331.6 in the nearby NGC5846 group by the Virtual Observatory (VO) workflow . This object (M_B = -15.98 mag, R_e = 0.24 kpc) becomes the fifth cE where the spatially-resolved kinematics and stellar populations can be obtained. We used archival HST WFPC2 images to demonstrate that its light profile has a two-component structure, and integrated photometry from GALEX, SDSS, UKIDSS, and Spitzer to build the multi-wavelength SED to constraint the star formation history (SFH). We observed this galaxy with the PMAS IFU spectrograph at the Calar-Alto 3.5m telescope and obtained two-dimensional maps of its kinematics and stellar population properties using the full-spectral fitting technique. Its structural, dynamical and stellar population properties suggest that it had a massive progenitor heavily tidally stripped by NGC5846.

The smeared intersecting 5-brane solution is used via the standard embedding to construct a heterotic background, which provides, after a compactification of some of the transverse dimensions, a five-dimensional Randall-Sundrum II like brane-world set-up in heterotic string theory. As a by-product, we present a new proof of anomaly cancellation between those from the chiral matter and the anomaly inflow onto the brane without small instanton.

Sex differences in exercise-induced arterial hypoxaemia and pulmonary oedema development following high intensity exercise in elite endurance athletes
Creators: name: Hind, Alanna Susan
Publisher: name: University of British Columbia
Year: 2024

description: Introduction: Elite female endurance athletes may be more susceptible to pulmonary limitations during exercise, such as exercise-induced arterial hypoxaemia (EIAH) when compared to males. Physiological mechanisms underlying EIAH in females are not fully understood, but may be related to pulmonary oedema development. This study examined pulmonary oedema and EIAH in male and female endurance athletes in a real-world environment. Methods: Twenty participants (10M vs. 10F; V̇ O₂: 68±8 vs. 52±5 ml∙kgˉ¹∙minˉ¹) performed spirometry and a maximal incremental cardiopulmonary exercise test on a treadmill (visit 1) followed by a maximal time trial on the Grouse Grind ® trail (2.9km, 800m elevation gain) in North Vancouver (visit 2). Only nineteen participants completed visit 2 (nine females) due to seasonal closures of the Grouse Grind ® trail. Pulmonary oedema was assessed 10 minutes following exercise using handheld lung ultrasound. Oxygen saturation (SpO₂), an index of EIAH, was recorded using finger pulse oximetry. Results: Average exercise duration and heart rate during the maximal time trial were 33.2±4.9min and 171±10bpm, and 39.3±3.4min and 174±8bpm for males and females respectively. The majority of participants developed EIAH at peak exercise (Mild: M:1, F:3; Moderate: M:7, F:2; Severe: M:2, F:4) with no sex differences in SpO₂ (M: 89±6% vs. F: 90±2%, respectively, p=0.30). There were no differences in post-exercise pulmonary oedema assessed using ultrasound b-line scores between males and females (0.9±1.1 vs. 1.9±2.2, respectively, p=0.60). Conclusion: Our findings suggest that a maximal time trial did not result in the development of pulmonary oedema in either male or female participants, while both sexes demonstrated similar development of EIAH at peak exercise. These findings add to our understanding of the physiological responses to exercise between sexes and highlights a need to investigate alternative mechanisms underlying previously documented sex differences in EIAH.

description: The physical conditions of the gas forming the narrow line regions (NLR) in active galactic nuclei (AGN) have been extensively studied in the optical band. We take advantage of the spectacular extension ($\sim$15") of the NLR in the type II Seyfert galaxy NGC 5252 and of the complementary characteristics of $XMM$--$Newton$ and $Chandra$ to investigate the physical conditions of the gas in this galaxy. The X-ray data from $XMM$--$Newton$ are used to define the spectral properties of the ionising nuclear source. The $Chandra$ data are used to trace the spatial characteristics of the soft X-ray emission. This information is then compared to the HST characteristics. The X-ray spectrum of the nucleus of NGC 5252 is intrinsically flat and absorbed by neutral gas with a column density N~10$^{22}$ cm$^{-2}$. Below 1 keV a soft excess is detected. The high-resolution spectrum obtained with the XMM-Newton RGS shows the presence, in the 0.2-1.5 keV range, of emission lines which strongly indicate that the soft X-ray component is due to ionised gas. Moreover, the soft X-ray emission is spatially resolved around and well overlaps the images obtained in narrow [OIII] optical band. The [OIII]/soft-X flux ratios along the ionisation cones is basically constant. This indicates that the electron density does not significantly deviates from the r$^{-2}$ law (constant ionisation parameter). This result combined with previous optical studies suggest two plausible but different scenarios in the reconstruction of the last 30000 years history of the central AGN. The most promising one is that the source is indeed a "quasar relic" with steady and inefficient energy release from the accretion of matter onto the central super-massive black-hole. This scenario is suggested also by the flat nuclear X-ray spectrum that suggests an advection dominate accretion flow (ADAF) like emission mechanism.

description: The transverse beam pattern, usually observed in experiment, is a result of averaging the optical-frequency oscillations of the electromagnetic field distributed over the beam cross section. An analytical criterion is derived that these oscillations are coupled with a sort of rotation around the beam axis. This criterion appears to be in direct relation with the usual definition of the beam orbital angular momentum.

description: Comparison of geometric quantities usually means obtaining generally true equalities of different algebraic expressions of a given geometric figure. Today's technical possibilities already support symbolic proofs of a conjectured theorem, by exploiting computer algebra capabilities of some dynamic geometry systems as well. We introduce GeoGebra's new feature, the Compare command, that helps the users in experiments in planar geometry. We focus on automatically obtaining conjectures and their proofs at the same time, including not just equalities but inequalities too. Our contribution can already be successfully used to support teaching geometry classes at secondary level, by getting several well-known and some previously unpublished result within seconds on a modern personal computer.

description: We provide a methodology for generating interatomic potentials for use in classical molecular dynamics simulations of atomistic phenomena occurring at energy scales ranging from lattice vibrations to crystal defects to high energy collisions. A rigorous method to objectively determine the shape of an interatomic potential over all length scales is introduced by building upon a charged-ion generalization of the well-known Ziegler-Biersack-Littmark universal potential that provides the short- and long-range limiting behavior of the potential. At intermediate ranges the potential is smoothly adjusted by fitting to ab initio data. Our formalism provides a complete description of the interatomic potentials that can be used at any energy scale, and thus, eliminates the inherent ambiguity of splining different potentials generated to study different kinds of atomic materials behavior. We exemplify the method by developing rigid-ion potentials for uranium dioxide interactions under conditions ranging from thermodynamic equilibrium to very high atomic energy collisions relevant for fission events.

description: We demonstrate an approach to improve poly-3-hexylthiophene field effect transistors by modifying the gold contacts with monolayer thick pentacenequinone (PQ) or naphthalene (NL). The effective contact resistance is reduced by a factor of two and sixteen for interlayers of PQ and NL, respectively. The observation is attributed to different injection barriers at the metal-organic interface caused by the functionalization and to an additional tunneling barrier enhancing the on/off ratios. This barrier yields to activation energies of 37meV (NL) and 104meV (PQ) below 190K, which are smaller than without functionalization, 117meV.

description: We present numerical simulations as well as experimental results concerning transitions between Taylor vortices and spiral vortices in the Taylor-Couette system with rigid, non-rotating end-walls in axial direction. As in the axial periodic case, these transitions are performed by wavy structures appearing via a secondary bifurcation out of Taylor vortices and spirals, respectively. But in the presence of rigid lids, pure spiral solutions do not occur but are substituted by primary bifurcating, stable wavy spiral structures (wSPI). Similarly to the periodic system, we found a transition from Taylor vortices to wSPI mediated by so called wavy Taylor vortices (wTVF) and, on the other hand, a transition from wSPI to TVF triggered by a propagating defect. We furthermore observed and investigated the primary bifurcation of wSPI out of basic Ekman flow.

description: The localized spin triplet ground state of a nitrogen vacancy (NV) center in diamond can be used in atomic-scale detection of local magnetic fields. Here we present a technique using these defects in diamond to image fields around magnetic structures. We extract the local magnetic field vector by probing resonant transitions of the four fixed tetrahedral NV orientations. In combination with confocal microscopy techniques, we construct a 2-dimensional image of the local magnetic field vectors. Measurements are done in external fields less than 50 G and under ambient conditions.

description: We investigate the evolution of linear perturbations in the Symmetric Teleparallel Gravity, namely $f(Q)$ gravity, for which we design the $f(Q)$ function to match specific expansion histories. We consider different evolutions of the effective dark energy equation of state, $w_Q(a)$, which includes $w_Q=-1$, a constant $w_Q \neq -1$ and a fast varying equation of state. We identify clear patterns in the effective gravitational coupling, which accordingly modifies the linear growth of large scale structures. We provide theoretical predictions for the product of the growth rate $\tilde{f}$ and the root mean square of matter fluctuations $σ_8$, namely $\tilde{f}σ_8$ and for the sign of the cross-correlation power spectrum of the galaxy fluctuations and the cosmic microwave background radiation anisotropies. These properties can be used to distinguish the $f(Q)$ gravity from the standard cosmological model using accurate cosmological observations.

Pig grazing as a regenerative alternative to tillage in market crop production : comparing cover crop growth and soil health indicators
Creators: name: Singfield, Corine
Publisher: name: University of British Columbia
Year: 2024

description: Cover crops are routinely used on farms to increase soil fertility, protect from erosion, and improve productivity. These green manure crops are predominantly managed with mechanical implements, which can cause adverse impacts on soil properties such as compaction, erosion, organic matter losses. The objective of this study was to investigate the viability of replacing tillage by using strip grazing pigs to manage cover crops (terminate and re-seed via trampling) and compare their impacts on cover crop growth and soil health to a system using typical tractor tillage. The experiment was conducted twice on two different areas of the same farm, one left fallow for 5 years, the other under previous organic market crop production. It was observed that cover crop coverage was 48% higher on average in the grazing system during the summer season and 35% more higher after a winter of growth. The proportion of weed cover varied according to the preceding land use; significantly more weeds were found in the tillage system where cropping activities had taken place before. Penetration resistance was significantly lower in the grazing system at the 15-30 cm depth which suggests it helped mitigate the plough pan layer. Mean aggregate stability was higher in the tillage system due to a higher fraction of macroaggregates even though there was a significantly higher fraction of microaggregates in the grazing system. Bulk density was not found to be significantly different between systems, but volumetric water content was significantly lower in the grazing plots. Nitrate levels were significantly higher in the grazing system, but grazing did not affect levels of ammonium, phosphorous, and permanganate oxidable carbon. Soil respiration was found to be significantly higher in the grazing system and mean earthworm count and weight were also 41% and 86% respectively. Overall, this study indicates that using grazing pigs to manage cover crops is a promising strategy that may help to prevent some of the negative impacts of tillage, even if used only over one growing season.
Desargues maps and the Hirota-Miwa equation

description: We study the Desargues maps $ϕ:\ZZ^N\to\PP^M$, which generate lattices whose points are collinear with all their nearest (in positive directions) neighbours. The multidimensional compatibility of the map is equivalent to the Desargues theorem and its higher-dimensional generalizations. The nonlinear counterpart of the map is the non-commutative (in general) Hirota--Miwa system. In the commutative case of the complex field we apply the nonlocal $\bar\partial$-dressing method to construct Desargues maps and the corresponding solutions of the equation. In particular, we identify the Fredholm determinant of the integral equation inverting the nonlocal $\bar\partial$-dressing problem with the $τ$-function. Finally, we establish equivalence between the Desargues maps and quadrilateral lattices provided we take into consideration also their Laplace transforms.

On the Infrared Behavior of Landau Gauge Yang-Mills Theory with a Fundamentally Charged Scalar Field

description: Recently it has been shown that infrared singularities of Landau gauge QCD can confine static quarks via a linearly rising potential. We show that the same mechanism can also provide a confining interaction between charged scalar fields in the fundamental representation. This confirms that within this scenario static confinement is a universal property of the gauge sector even though it is formally represented in the functional equations of the matter sector. The simplifications compared to the fermionic case make the scalar system an ideal laboratory for a detailed analysis of the confinement mechanism in numerical studies of the functional equations as well as in gauge-fixed lattice simulations.

Red Variable Stars in Three M81 Group Dwarf Galaxies

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Archival [3.6] and [4.5] images are used to identify and characterize variable stars in the Magellanic-type galaxies Holmberg II, NGC 2366, and IC 2574. Using parametric and non-parametric detection methods, 74 confirmed or suspected long period variables (LPVs) are found. The period distributions of the LPVs in NGC 2366 and IC 2574 are similar. While the period distribution of LPVs in Ho II is uncertain due to small number statistics there appears to be a deficiency of LPVs with periods between 550 and 650 days when compared with NGC 2366 and IC 2574. The LPVs are diffusely distributed on the sky, and do not follow the underlying light from unresolved stars, as expected if episodes of star formation within the past few hundred Myr have occurred throughout the galaxies, including their outer regions. Distances computed for Ho II and NGC 2366 from the period-luminosity relations (PLRs) agree to within ~0.1 magnitudes with those based on the tip of the red giant branch (RGB). Efforts to estimate an LPV-based distance modulus for IC 2574 are complicated by the presence of first overtone pulsators among LPVs with periods ~ 600 days, although the PLR at the long period end is consistent with the distance estimated from the RGB-tip. In addition to the LPVs, 10 candidate sgB[e] or luminous blue variables and 2 candidate red supergiant variables are also identified. Nine candidate sgB[e] stars that do not show evidence of variability are also identified based on their locations in the color-magnitude diagram.

description: The development of electronic commerce is characterized with anonymity, uncertainty, lack of control and potential opportunism. Therefore, the success of electronic commerce significantly depends on providing security and privacy for its consumers sensitive personal data. Consumers lack of acceptance in electronic commerce adoption today is not merely due to the concern on security and privacy of their personal data, but also lack of trust and reliability of Web vendors. Consumers trust in online transactions is crucial for the continuous growth and development of electronic commerce. Since Business to Consumer (B2C) ecommerce requires the consumers to engage the technologies, the consumers face a variety of security risks. This study addressed the role of security, privacy and risk perceptions of consumers to shop online in order to establish a consensus among them. The analyses provided descriptive frequencies for the research variables and for each of the study s research constructs. In addition, the analyses were completed with factor analysis and Pearson correlation coefficients. The findings suggested that perceived privacy of online transaction on trust is mediated by perceived security, and consumers trust in online transaction is significantly related with the trustworthiness of Web vendors. Also, consumers trust is negatively associated with perceived risks in online transactions. However, there is no significant impact from perceived security and perceived privacy to trust in online transactions.
