description: We theoretically study the three-dimensional topological semimetals with nodal surfaces protected by crystalline symmetries. Different from the well-known nodal-point and nodal-line semimetals, in these materials, the conduction and valence bands cross on closed nodal surfaces in the Brillouin zone. We propose different classes of nodal surfaces, both in the absence and in the presence of spin-orbit coupling (SOC). In the absence of SOC, a class of nodal surfaces can be protected by spacetime inversion symmetry and sublattice symmetry and characterized by a $\mathbb{Z}_2$ index, while another class of nodal surfaces are guaranteed by a combination of nonsymmorphic two-fold screw-rotational symmetry and time-reversal symmetry. We show that the inclusion of SOC will destroy the former class of nodal surfaces but may preserve the latter provided that the inversion symmetry is broken. We further generalize the result to magnetically ordered systems and show that protected nodal surfaces can also exist in magnetic materials without and with SOC, given that certain magnetic group symmetry requirements are satisfied. Several concrete nodal-surface material examples are predicted via the first-principles calculations. The possibility of multi-nodal-surface materials is discussed.

Se reconstruire par la dénonciation : Proposition d'une lecture féministe des récits des survivantes autochtones de violences au Québec
Creators: name: Lainé, Mazarine
Publisher: name: My University
Year: 2019

description: Ce mémoire s’intéresse aux expériences des femmes autochtones survivantes de violence coloniale en contexte québécois. Il vise à contribuer au débat par la mise en avant des expériences des femmes autochtones, en restituant les paroles des survivantes sur la question de la violence à leur endroit. Nous présenterons les stratégies de résilience que ces récits révèlent, afin de mettre un terme à la vision culpabilisante/victimaire que nous avons à l’encontre de ces femmes et de rendre compte de leur agentivité. Ce mémoire repose sur une approche qualitative et biographique pour analyser les récits des femmes autochtones survivantes. La posture féministe postcoloniale exige une réflexion sur la positionnalité de l’autrice. Cette positionnalité s’articule au fait qu’elle est une femme racisée issue de l’immigration postcoloniale des anciennes colonies françaises et vivant sur des territoires autochtones non-cédés. L’ancrage de ce positionnement dans le travail a été fait à travers une approche autoethnographique critique ainsi que par la théorie du positionnement féministe.

description: We explore the possibility that the anomalous split in the Subgiant branch of the galactic globular cluster NGC 1851 is due to the presence of two distinct stellar populations with very different initial metal mixtures: a normal alpha-enhanced component, and one characterized by strong anticorrelations among the CNONa abundances, with a total CNO abundance increased by a factor of two. We test this hypothesis taking into account various empirical constraints, and conclude that the two populations should be approximately coeval, with the same initial He-content. More high-resolution spectroscopical measurements of heavy elements -- and in particular of the CNO sum -- for this cluster are necessary to prove (or disprove) this scenario.

description: La propuesta se enfoca en el análisis del rol social de los niños y niñas de Nueva Esperanza en el polígono TCE durante el periodo Muisca Temprano, con énfasis en prácticas funerarias. Desde una perspectiva social, se destaca la importancia asignada a estos niños como agentes sociales. Se realizó un análisis detallado de la materialidad en tumbas y marcadores arqueológicos, considerando aspectos como posición anatómica, estructura y dimensiones, así como marcadores como el modelamiento cefálico. Aunque existen estudios previos sobre la infancia en Nueva Esperanza, la investigación aborda un vacío investigativo en el rol social de los niños en el contexto prehispánico. Los resultados revelan respuestas simbólicas a la muerte, evidenciando la interconexión entre materialidad y rol social. Se destaca la diversidad en el tratamiento funerario de los niños, indicando posibles diferencias de roles. Estos hallazgos contribuyen al entendimiento de la niñez en el pasado y ofrecen perspectivas valiosas para futuras investigaciones, abordando la esencia de lo humano mediante la representación simbólica en prácticas rituales y proporcionando información sobre la identidad cultural de un grupo poco estudiado en la arqueología colombiana, los no mencionados, las niñas y niños del pasado.
description: The proposal focuses on analyzing the social role of boys and girls from Nueva Esperanza in the TCE polygon during the Early Muisca period, with an emphasis on funerary practices. From a social perspective, the importance assigned to these children as social agents is highlighted. A detailed analysis of materiality in tombs and archaeological markers was carried out, considering aspects such as anatomical position, structure, and dimensions, as well as markers like cranial modeling. Despite previous studies on childhood in Nueva Esperanza, the research addresses an investigative gap in the social role of children in the pre-Hispanic context. The results reveal symbolic responses to death, demonstrating the interconnection between materiality and social role. The diversity in the funerary treatment of children is emphasized, indicating possible role differences. These findings contribute to understanding childhood in the past and offer valuable perspectives for future research, addressing the essence of humanity through symbolic representation in ritual practices and providing information about the cultural identity of a little-studied group in Colombian archaeology—the unmentioned, the girls, and boys of the past.

description: Anthony of a Parma, was an Italian philosopher and medical scholar active in the first three decades of the fourteenth century, whose favorite philosophical authorities were Aristotle and Averroes. He is the author of an intriguing disputed question in which he argues that it is possible to demonstrate that God has infinite power. This article seeks to explicate Anthony’s key arguments in support of this thesis as well as to identify the main contemporary sources behind them. It also highlights the peculiar way in which Anthony attempts to resolve the inconsistency between his position, which ultimately relies on Aristotle and Averroes, and that of the Catholic faith whose truth, he contends, “must in all matters always be put forward,” even though it appears to imply that Aristotle’s position is “totally impossible and false.” The article is followed by the critical edition of the quaestio.

description: The band structures of bulk transition metal dichalcogenides ReS2 and ReSe2 are presented, showing the complicated nature of the interband transitions in these materials, with several close-lying band gaps. Three-dimensional plots of constant energy surfaces in the Brillouin zone at energies near the band extrema are used to show that the valence band maximum and conduction band minimum may not be located at special high symmetry points. We find that both materials are indirect gap materials and that one must be careful to consider the whole Brillouin zone volume in addressing this question.

description: Recent studies have presented evidence for tension between the constraints on Omega_m and sigma_8 from the cosmic microwave background (CMB) and measurements of large-scale structure (LSS). This tension can potentially be resolved by appealing to extensions of the standard model of cosmology and/or untreated systematic errors in the modelling of LSS, of which baryonic physics has been frequently suggested. We revisit this tension using, for the first time, carefully-calibrated cosmological hydrodynamical simulations, which thus capture the back reaction of the baryons on the total matter distribution. We have extended the BAHAMAS simulations to include a treatment of massive neutrinos, which currently represents the best motivated extension to the standard model. We make synthetic thermal Sunyaev-Zel'dovich effect, weak galaxy lensing, and CMB lensing maps and compare to observed auto- and cross-power spectra from a wide range of recent observational surveys. We conclude that: i) in general there is tension between the primary CMB and LSS when adopting the standard model with minimal neutrino mass; ii) after calibrating feedback processes to match the gas fractions of clusters, the remaining uncertainties in the baryonic physics modelling are insufficient to reconcile this tension; and iii) if one accounts for internal tensions in the Planck CMB dataset (by allowing the lensing amplitude, A_Lens, to vary), invoking a non-minimal neutrino mass, typically of 0.2-0.4 eV, can resolve the tension. This solution is fully consistent with separate constraints from the primary CMB and baryon acoustic oscillations.

description: Aim: A preliminary analysis was done to evaluate the impact of lockdown on soil temperature at different depths and comparison with year 2018 and 2019. Methodology and Results: In order to describe the basic features of the data in study, descriptive statistics method was opted. The deviation in soil temperature in Rajouri District from mean value at 5 cm depth observed during lockdown was -8.58% and -4.77% compared to year 2018 and 2019. However the deviation observed from mean value at 10 cm depth was -10.72% and -9.28%. The deviation from mean value at 20 cm depth observed was -2.34% and -1.98%. The average change in soil temperature in Jammu District in morning at 5 cm, 10 cm and 20 cm depth was -3.46%, -3.84% and -7.23% as compared to year 2019 (22nd March to 10th June 2019) mean value and the change in soil temperature in evening at same depths was -7.69%, -6.31% and -4.14% from year 2019 (22nd March to 10th June 2019). The much focus is on Rajouri District as compared to Jammu, so tables and figures are representing Rajouri situation. Conclusion: The study concluded that due to lockdown, there was significant change in soil temperature values at variable depths compared to year 2018 and 2019 in the study region.

description: Efficiently and accurately searching for similarities among time series and discovering interesting patterns is an important and non-trivial problem. In this paper, we introduce a new representation of time series, the Multiresolution Vector Quantized (MVQ) approximation, along with a new distance function. The novelty of MVQ is that it keeps both local and global information about the original time series in a hierarchical mechanism, processing the original time series at multiple resolutions. Moreover, the proposed representation is symbolic employing key subsequences and potentially allows the application of text-based retrieval techniques into the similarity analysis of time series. The proposed method is fast and scales linearly with the size of database and the dimensionality. Contrary to the vast majority in the literature that uses the Euclidean distance, MVQ uses a multi-resolution/hierarchical distance function. We performed experiments with real and synthetic data. The proposed distance function consistently outperforms all the major competitors (Euclidean, Dynamic Time Warping, Piecewise Aggregate Approximation) achieving up to 20% better precision/recall and clustering accuracy on the tested datasets.

description: Traumatic exposure in childhood can result in impairments in social relatedness as well as cognitive and emotional dysregulation (Cook et al., 2005). Program leaders trained in trauma-informed approaches can design and deliver sport-based programming that can help restore youths’ social and self-regulatory capacities and orient them toward thriving (Bergholz et al., 2016). However, little research has explored the learning experiences of program leaders as they apply trauma-informed approaches in youth sport. Wenger and colleagues’ (2011) value-creation cycle offers a useful framework to assess the value that is enabled (e.g., changes to one’s self and/or one’s social environment) from leaders’ learning interactions (e.g., training workshops). This study’s purpose was to assess the learning experiences of program leaders who implemented trauma-informed sport programming in a national youth organisation. Twelve leaders participated in three training workshops as they implemented programming in three pilot sites across Canada for eight months. The data were gathered through interviews and observations of leaders’ discussions. The value-creation framework was used to categorise learning experiences based on the interactions and values that leaders discussed. The results indicate that leaders’ encountered various learning interactions (e.g., training workshops, applied practice, peer discussions), and discussed gains in immediate value (e.g., enjoyment, peer-relationships), perceived value (e.g., knowledge and awareness of neuroscience/trauma, program delivery strategies), applied value (e.g., coaching skills, youth-support skills, youths’ receptivity), realised value (e.g., expertise, youths’ behaviour change), and transformative value (e.g., transfer of skills, influence on club culture). Implications are discussed for program improvement and ongoing program leaders’ education.

The comet was at a heliocentric distance greater than 3\,{\sc au} during both sets of observations. The images showed a well-developed tail with properties that suggested it was an ion tail. The spectra confirmed that we were observing well-developed bands of CO$^+$ and N$_2^+$. The N$_2^+$ detection was unequivocally cometary and was one of the strongest bands of N$_2^+$ detected in a comet spectrum. We derived the ratio of these two ions and from that we were able to derive that N$_2$/CO = 0.15. This is the highest such ratio reported for a comet. Note erratum - N2/CO=0.06 not 0.15.

description: The preconception origins hypothesis holds that some of the preconception and prenatal environmental factors that have been shown to determine the offspring sex ratio also explain sex differences in early-age mortality (Pongou 2013). It extends and complements the biological hypothesis, which affirms that the mortality sex gap originates in biological and genetic differences between the sexes. As such, it offers a broad framework for understanding changes in male–female differences in early-age mortality across space and over time. I argue that this hypothesis is consistent with the concurrent increase in the proportion of female births and in the relative mortality of female to male infants in the United States since World War II. / L’hypothèse des origines préconceptionnelles affirme que certains facteurs auxquels les parents sont soumis pendant la période préconceptionnelle et prénatale et qui déterminent le sexe de l’enfant expliquent partiellement les différences de mortalité entre les garçons et les filles en bas âge (Pongou 2013). Cette hypothèse généralise et complémente l’hypothèse biologique selon laquelle l’écart de mortalité entre les garçons et les filles provient des différences biologiques et génétiques entre les sexes. Ainsi, cette hypothèse offre un cadre général qui permet de mieux comprendre les changements dans la différence de mortalité entre les sexes dans le temps et l’espace. Je montre que cette hypothèse est cohérente avec l’augmentation parallèle de la proportion des naissances féminines et de la mortalité infantile des filles relativement à cette des garçons aux États-Unis depuis la fin de la deuxième guerre mondiale.

description: Abstract: "This paper presents a stereo matching method which uses multiple stereo pairs with various baselines to obtain precise depth estimates without suffering from ambiguity. In stereo processing, a short baseline means that the estimated depth will be less precise due to narrow triangulation. For more precise depth estimation, a longer baseline is desired. With a longer baseline, however, a larger disparity range must be searched to find a match. As a result, matching is more difficult and there is a greater possibility of a false match. So there is a trade-off between precision and accuracy in matching.The stereo matching method presented in this paper uses multiple stereo pairs with different baselines generated by a lateral displacement of a camera. Matching is performed simply by computing the sum of squared-difference (SSD) values. The SSD functions for individual stereo pairs are represented with respect to the inverse depth (rather than the disparity, as is usually done), and then are simply added to produce the sum of SSDs. This resulting function is called the SSSD-in-inverse-depth. We show that the SSSD-in-inverse-depth function exhibits a unique and clear minimum at the correct matching position even when the underlying intensity patterns of the scene include ambiguities or repetitive patterns.An advantage of this method is that we can eliminate false matches and increase precision without any search or sequential filtering. This paper first defines a stereo algorithm based on the SSSD-in-inverse-depth and presents a mathematical analysis to show how the algorithm can remove ambiguity and increase precision. Then, a few experimental results with real stereo images are presented to demonstrate the effectiveness of the algorithm."
Prescription Drug Insurance and Demand for Physician Services: Evidence from Ontario and New Brunswick
Creators: name: Glaser, Sheena M
Publisher: name: My University
Year: 2016

description: This paper examines the marginal impact of supplemental prescription drug cover- age on demand for physician services within a publicly funded health care system. The data comes from three cycles of the Canadian Community Health Survey for Ontario and New Brunswick. The probability of at least one consultation per year is estimated using a probit model. Then users of health care services are divided into high and low frequency latent classes, and the number of consultations per year is estimated using a negative binomial model. This paper is the first to consider the impact by type of insurance (government-provided, employer-provided, or privately purchased) separately for family doctors and specialists for both individuals under 65 and seniors. These results confi rm that having supplemental insurance increases the likelihood of a visit to both a family doctor and a specialist. This paper also finds that the number of consultations with family doctors and specialists are sensitive to the type of insurance, not only the presence of insurance. In general, the greatest impacts can be seen from specialist visits and among low frequency latent class users.

description: We systematically study the modifications in the couplings of the Higgs boson, when identified as a pseudo Nambu-Goldstone boson of a strong sector, in the light of LHC Run 1 and Run 2 data. For the minimal coset SO(5)/SO(4) of the strong sector, we focus on scenarios where the standard model left- and right-handed fermions (specifically, the top and bottom quarks) are either in 5 or in the symmetric 14 representation of SO(5). Going beyond the minimal 5L-5R representation, to what we call here the 'extended' models, we observe that it is possible to construct more than one invariant in the Yukawa sector. In such models, the Yukawa couplings of the 125 GeV Higgs boson undergo nontrivial modifications. The pattern of such modifications can be encoded in a generic phenomenological Lagrangian which applies to a wide class of such models. We show that the presence of more than one Yukawa invariant allows the gauge and Yukawa coupling modifiers to be decorrelated in the 'extended' models, and this decorrelation leads to a relaxation of the bound on the compositeness scale (f > 640 GeV at 95% CL, as compared to f > 1 TeV for the minimal 5L-5R representation model). We also study the Yukawa coupling modifications in the context of the next-to-minimal strong sector coset SO(6)/SO(5) for fermion-embedding up to representations of dimension 20. While quantifying our observations, we have performed a detailed chi-square fit using the ATLAS and CMS combined Run 1 and available Run 2 data.

description: We present a robot that is able to interact with people in a natural, multi-modal way by using both speech and gesture. The robot is able to track people, process speech and understand language. To track people and recognize gestures, the robot uses an RGB-D sensor (e.g., a Microsoft Kinect). To recognize speech, the robot uses a cloud-based service. To understand language, the robot uses a probabilistic graphical model to infer the meaning of a natural language query. We have evaluated our system in two domains. The first domain is a robot receptionist (roboceptionist); we show that the roboceptionist is able to interact successfully with people 77% of the time when people are primed with the capabilities of the robot compared to 57% when people are not primed with its capabilities. The second domain is a mobile service robot, which is able to interact with people via natural language.

description: We present a comparison of the SCUBA half degree extragalactic survey (SHADES) at 450 μm, 850 μm and 1100 μm with deep guaranteed time 15 μm AKARI FU-HYU survey data and Spitzer guaranteed time data at 3.6-24 μm in the Lockman hole east. The AKARI data was analysed using bespoke software based in part on the drizzling and minimum-variance matched filtering developed for SHADES, and was cross-calibrated against ISO fluxes. Our stacking analyses find AKARI 15 μm galaxies with 200 μJy contribute >10% of the 450 μm background, but only <4% of the 1100 μm background, suggesting that different populations contribute at mm-wavelengths. We confirm our earlier result that the ultra-deep 450 μm SCUBA-2 cosmology survey will be dominated by populations already detected by AKARI and Spitzer mid-infrared surveys. The superb mid-infrared wavelength coverage afforded by combining Spitzer and AKARI photometry is an excellent diagnostic of AGN contributions, and we find that (23-52)% of submm-selected galaxies have AGN bolometric fractions fAGN > 0.3.

description: There is a pressing need to equip youth-serving community organizations to respond to the unique needs of trauma-exposed children. Early prevention measures can be an effective means of redirecting children to self-regulatory healing, while facilitating their transition toward strength-based thriving. Sport can offer a powerful opportunity to reach these children, given the popular, enjoyable, and motivating nature of these environments, and the potential to reach many unscreened trauma-exposed children. The purpose of this project was to develop, implement, and evaluate sport-based trauma-informed practices with the Boys & Girls Clubs of Canada’s national Bounce Back League. Programs that use sport-based trauma-informed practices can offer healthy psychological escape through high levels of engagement, and feelings of embodiment and control through opportunities for skill-building. These positive program experiences can help orient these children toward pathways of resilience and thriving.
Swimming trajectories of a three-sphere microswimmer near a wall

description: The hydrodynamic flow field generated by self-propelled active particles and swimming microorganisms is strongly altered by the presence of nearby boundaries in a viscous flow. Using a simple model three-linked sphere swimmer, we show that the swimming trajectories near a no-slip wall reveal various scenarios of motion depending on the initial orientation and the distance separating the swimmer from the wall. We find that the swimmer can either be trapped by the wall, completely escape, or perform an oscillatory gliding motion at a constant mean height above the wall. Using a far-field approximation, we find that, at leading order, the wall-induced correction has a source-dipolar or quadrupolar flow structure where the translational and angular velocities of the swimmer decay as inverse third and fourth powers with distance from the wall, respectively. The resulting equations of motion for the trajectories and the relevant order parameters fully characterize the transition between the states and allow for an accurate description of the swimming behavior near a wall. We demonstrate that the transition between the trapping and oscillatory gliding states is first order discontinuous, whereas the transition between the trapping and escaping states is continuous, characterized by non-trivial scaling exponents of the order parameters. In order to model the circular motion of flagellated bacteria near solid interfaces, we further assume that the spheres can undergo rotational motion around the swimming axis. We show that the general three-dimensional motion can be mapped onto a quasi-two-dimensional representational model by an appropriate redefinition of the order parameters governing the transition between the swimming states.

title: Εκτίμηση ευστάθειας τετραεδρικών σφηνών σε υπόγεια ανοίγματα με την χρήση αριθμητικής μεθόδου ανάλυσης στις 3 διαστάσεις

description:  Η συγκεκριμένη διπλωματική εργασία εκπονήθηκε με σκοπό να δείξει τη χρήση και κυρίως τα αποτελέσματα ορισμένων μεθόδων όπως η μέθοδος της χαλάρωσης των τάσεων και η μέθοδος της διατμητικής αντοχή για την εκτίμηση του συντελεστή ασφαλείας πτώσης βραχοσφηνών διαφόρων σχημάτων και μεγεθών, σε υπόγεια ανοίγματα – σήραγγες. Το πρόβλημα της αποκόλλησης σφηνών από την οροφή άλλα και από τις παρειές της στοάς και γενικά οι τοπική κατάρρευση της οροφής της εκσκαφής είναι από τους κυριότερους κινδύνους που παραμονεύουν σε ένα υπόγειο μεταλλείο. Λόγω του μεγάλου αριθμού ατυχημάτων η προσπάθεια να εκτιμηθεί ο κίνδυνος είναι αναγκαία. Βέβαια, είναι πάρα πολύ δύσκολο έως ακατόρθωτο να εκτιμηθεί ο Συντελεστής Ασφαλείας [ΣΑ] σε όλο το μήκος της στοάς και για όλες τις τυχόν σφήνες που δημιουργούνται λόγω της πολυπλοκότητας του συστήματος. Στην παρούσα εργασία, αρχικά γίνεται ο υπολογισμός του ΣΑ αναλυτικά στις δύο διαστάσεις, για συγκεκριμένη σφήνα στην οροφή, χρησιμοποιώντας τις εξισώσεις του Kirsch για κυκλικό άνοιγμα. Έπειτα, συγκρίνεται με τον ΣΑ της σφήνας που υπολογίζεται με βάση τις τάσεις από την αριθμητική επίλυση μέσω της MATLAB με την μέθοδο των ασυνεχών μετατοπίσεων πάλι στις δύο διαστάσεις αυξάνοντας κάθε φορά τα στοιχεία διακριτοποίησης του συνόρου – κύκλου. Εν συνεχεία, γίνεται ο υπολογισμός του ΣΑ ασφαλείας της σφήνας στις 3 διαστάσεις με την αριθμητική μέθοδο των ασυνεχών μετατοπίσεων να εκτελείται για τον υπολογισμό των τάσεων και συγκρίνεται με τις τιμές του ΣΑ που υπολογίστηκαν στις δύο διαστάσεις. Τέλος, γίνεται σύγκριση του ΣΑ που προκύπτει από το unwedge και από τις προηγούμενες μεθόδους με βάση ορισμένα μηχανικά χαρακτηριστικά της βραχόμαζας και παρουσιάζονται τα διαγράμματα.

description: In this paper, we consider the estimation of a mean vector of a multivariate normal population where the mean vector is suspected to be nearly equal to mean vectors of $k-1$ other populations. As an alternative to the preliminary test estimator based on the test statistic for testing hypothesis of equal means, we derive empirical and hierarchical Bayes estimators which shrink the sample mean vector toward a pooled mean estimator given under the hypothesis. The minimaxity of those Bayesian estimators are shown, and their performances are investigated by simulation.
