description: The two-loop formfactor both for a U(1)xU(1) and a SU(2)xU(1) gauge theory with massive and massless gauge bosons respectively is evaluated at arbitrary momentum transfer q^2. The asymptotic behaviour for q^2->\infinity is compared to a recent calculation of Sudakov logarithms. The result is an important ingredient for the calculation of radiative corrections to Z-boson production at hadron and lepton colliders.

Black student perceptions of restorative justice circles and associated social emotional learning gains
Creators: name: Molyneaux, Crystal N.
Publisher: name: No Publisher Supplied
Year: 2022

description: Despite the aspirations of restorative justice (RJ), there has been little empirical research that has systematically examined student experience of RJ and student-perceived social and emotional benefits of RJ circles. The current study addresses gaps in knowledge about RJ circles using a mixed methods study. The author used student voice to better understand student-reported circle benefits. The sample was comprised of approximately 445 students from three predominately Black middle and high schools located in a Northeastern U.S. city during 2018. Analysis of student-reported circle benefits found that a majority of student responses could be grouped into the Social Awareness, Self-Awareness, Relationship Skills and Responsible Decision-Making social-emotional learning (SEL) competencies. These student perceptions were referred to as social and emotional circle benefits (SECB). To better understand the experience of Black students, in an effort to identify how this population can be better supported in school systems, SECB was examined further by race (Black compared to students from other race/ethnic groups) and gender (male compared to non-male). Results indicated no gender differences in student discussions of SECB. In contrast, Black students, relative to students from other racial/ethnic groups, slightly reported fewer SEL-oriented circle benefits. Using multiple regression, the study also found that SECB was significantly associated with three indicators of positive school climate, as measured by adult support, sense of safety, and sense of community. In other words, when students perceived greater SEL-oriented benefits through their circle participation, they also tended to report greater support, safety, and community in their school, relative to their peers who saw fewer circle benefits. This implies that there should be more consideration given to the explicit inclusion of SEL curricula. Also, given the fewer reported SECBs by Black students, cultural relevance during community-building circles should be targeted with the consideration of cultural synchrony between community-building circles, Black students, and protective parenting.
Assessment of tsunami hazards on the British Columbia coast due to a local megathrust subduction earthquake
Creators: name: Ng, Max Kin-Fat
Publisher: name: University of British Columbia
Year: 2010

description: Strong evidence suggests that the Cascadia subduction zone, off the west coast of Canada and the United States, is strongly seismically-coupled and that a possible megathrust earthquake might occur in that area in the near future. A study of tsunami hazards along the Canadian west coast associated with such a hypothetical earthquake is presented in this report. Numerical simulations of tsunami generation and propagation have been carried out using three models based on shallow water wave theory. Three cases of ground motion representing the ruptures of different crustal segments in the area have been examined. Computed results provide information on tsunami arrival times and a general view of the wave height distribution. The outer coast of Vancouver Island was found to be the most strongly affected area. At the head of Alberni Inlet, wave amplitudes reached up to three times the source magnitude. Inside the Strait of Georgia, the wave heights are significant enough to receive closer attention, especially in low-lying areas.

description: The striking results on noncrossed products were their existence (Amitsur) and the determination of Q(t) and Q((t)) as their smallest possible centres (Brussel). This paper gives the first fully explicit noncrossed product example over Q((t)). As a consequence, the use of deep number theoretic theorems (local-global principles such as the Hasse norm theorem and density theorems) in order to prove existence is eliminated. Instead, the example can be verified by direct calculations. The noncrossed product proof is short and elementary.

description: We report a systematic study of the bias-dependent contact resistance in rubrene single-crystal field-effect transistors with Ni, Co, Cu, Au, and Pt electrodes. We show that the reproducibility in the values of contact resistance strongly depends on the metal, ranging from a factor of two for Ni to more than three orders of magnitude for Au. Surprisingly, FETs with Ni, Co, and Cu contacts exhibits an unexpected reproducibility of the bias-dependent differential conductance of the contacts, once this has been normalized to the value measured at zero bias. This reproducibility may enable the study of microscopic carrier injection processes into organic semiconductors.

description: The deformation potentials of cubic semiconductors are re-examined from the point of view of the extended-basis $sp^3d^5s^*$ tight-binding model. Previous parametrizations had failed to account properly for trigonal deformations, even leading to incorrect sign of the acoustic component of the shear deformation potential {\it d}. The strain-induced shifts and splittings of the on-site energies of the p- and d-orbitals are shown to play a prominent role in obtaining satisfactory values of deformation potentials both at the zone center and zone extrema. The present approach results in excellent agreement with available experimental data and ab-initio calculations.

description: Birefringence measurements have been carried out on the Pb-doped silica hydrogels prepared under various magnetic fields up to 5T. The silica gels prepared at 5T were used as a medium of crystal growth of PbBr2, whose result implied the structural anisotropy; an aligned array of crystallites was obtained by transmission electron microscopy. While the samples prepared at 0, 1, and 3T have no birefringence, we found that the samples have negative birefringence on the order of magnitude 10^-6 as if the direction of the magnetic field is the optic axis of a uniaxal crystal. To the authors' knowledge, the birefringent silica hydrogels were obtained by gelation under magnetic field for the first time. Also, scanning microscopic light scattering experiments have been performed. The results indicate that the characteristic length distribution for birefringent samples is narrower than that for non-birefringent ones.

description: The purpose of the present study is the evaluation of the changes in the size and movement of the pupil in patients with major depression with melancholic features and in patients with bipolar disorder type I, using pupillometry, in comparison with normal subjects, as well as the study of the changes of the autonomous nervous system in these affective disorders, using pupillometry. For the depressed patient group, the scores for maximum acceleration were significantly decreased as compared to those of normal subjects. Also, in comparison to the database for the measurement of various parameters of the pupil light reflex in normal subjects, which were obtained from the Laboratory of Clinical Neurophysiology of the Aristotle University of Thessaloniki, scores of depressed patients were doubtlessly pathological. The scores of maximum acceleration (mean) in bipolar patients were decreased as compared to those of normal subjects but with a small f-value. An increase of the sympathetic tone produces reduction in maximum velocity and maximum acceleration, while an increase in the parasympathetic tone augments the scores of these parameters. The application of pupillometry in patients with affective disorders, can provide objective information about the function of autonomous nervous system that could be useful in the prognosis and therapy of the patient.

 Ixodes vespertilionis is a bat tick that has a very wide distribution in Europe and Asia (Guglielmone et al. 2014; Estrada-Peña et al. 2018). In continental Southeast Asia it has been recorded from Lao PDR and Thailand, with other Asian records from China, including Taiwan, South Korea and Japan (Yamaguti et al. 1971; Tanskul et al. 1983; Teng and Jiang 1991; Robbins 2005; Chen et al. 2010; Kim et al. 2011; Bush and Robbins 2012; Vongphayloth et al. 2018a). Recently, I. collaris was described from Vietnam, and it is possible that other Asian records have been confused with this species (Hornok et al. 2016).
 All life history stages are illustrated in Yamaguti et al. (1971).

Open clusters in dense fields: the importance of field-star decontamination for NGC5715, Lynga4, Lynga9, Trumpler23, Trumpler26 and Czernik37

description: Star clusters projected onto dense stellar fields require field star decontamination to confirm their nature and derive intrinsic photometric and structural fundamental parameters. The present work focusses on the OCs or candidates NGC5715, Lynga4,9, Trumpler23,26 and Czernik37 which are projected against crowded bulge and/or disc fields. We develop a CMD field star decontamination algorithm based on 2MASS data, and respective uncertainties, to detect cluster star excesses over the background. On the other hand, colour-magnitude filters are used to build stellar radial density profiles and mass functions. The results convey compelling evidence that Ly9 and Cz37 are intermediate-age open clusters, and their fundamental parameters are measured for the first time. Tr23 is a particularly challenging object, since besides high background level, its field presents variable absorption in near-IR bands. We confirm it to be an intermediate-age open cluster. These OCs are located 0.9 - 1.6kpc within the Solar Circle, with ages similar to that of the Hyades. Structurally, they are well described by King profiles. In all cases, core and limiting radii are significantly smaller than those of nearby OCs outside the Solar circle. We test the effect of background levels on cluster radii determinations by means of simulations. They indicate that for central clusters, radii may be underestimated by about 10--20%, which suggests that the small sizes measured for the present sample reflect as well intrinsic properties related to dynamical evolution effects. The objects probably have been suffering important tidal effects that may have accelerated dynamical evolution, especially in Cz37, the innermost object.

description: This is a fact sheet reporting bullet pointed findings that extend a previous working paper. Additional tables from the StatsNZ R&D Survey were obtained from StatsNZ Infoshare to produce these results. Current and future gains from increased Business R&D may be limited by a large and growing gap between employment of PhD-qualified researchers in Business R&D. Positions for 4300 PhD-qualified researchers would be needed to bring the Business R&D sector to one PhD FTE per $0.5 m R&D expenditure, currently. At this ratio, twice this estimate (8600 FTE) will be required for R&D to reach 2% of GDP.
Presence of cell-cycle dependent substructure at low dose in the radiation survival response of asynchronous V79-WNRE cells
Creators: name: Skwarchuk, Mark William
Publisher: name: University of British Columbia
Year: 2010

description: Survival studies using cell sorting techniques together with data averaging on asynchronously dividing V79-WNRE cells reveal statistically significant evidence of substructure in the radiation survival response at low dose (2 to 3 Gy) that cannot be adequately characterized by a single linear-quadratic function, S = exp( -αD -βD²). The data suggest a two-component response that is particularly evident when plotted in the linear form of the linear-quadratic equation, -ln(S)/D = α + βD. Application of other survival models (Single Hit + Multi Target and Repair-Misrepair) does not eliminate the substructure. The substructure may result from subpopulations of cells at different stages of the cell cycle, which differ in their radiosensitivity, giving rise to a two-component survival response. In order to explore this hypothesis, studies were carried out with populations of partially synchronized cells. The mitotic selection technique was employed alone or in combination with 12 hours exposure to 1 mM hydroxyurea or 1 μg/ml aphidicolin to obtain large numbers of synchronized cells. G1/S phase populations obtained by mitotic selection followed by hydroxyurea or aphidicolin do not show the substructure found for asynchronous cells, thus supporting the hypothesis. G1 phase populations obtained by mitotic selection alone revealed substructure which could be characterized by a single fit to the RMR or SH+MT models. Structure was also present in the response of heterogeneous S/G2 phase populations synchronized by mitotic selection followed by hydroxyurea, but may not be present in the response of S phase populations synchronized by mitotic selection alone. The data are consistent with the hypothesis that the substructure is a result of sensitive (G1, G2 or M) and resistant (S) subpopulations of cells.

A proton polarimeter for pion physics at TRIUMF
Creators: name: Pavan, Marcello Maurizio
Publisher: name: University of British Columbia
Year: 2010

description: A proton polarimeter employing multi-wire delay-line drift chambers (MWDDCs) has been built for ongoing pion absorption studies in the meson area at TRIUMF. A brief introduction of the theoretical basis of polarimeter and MWDCC operation is offered. An in-depth study of our own system is presented including an account of the data acquisition readout electronics and the procedures used for wire chamber position calibration. Detailed performance specifications of all aspects of our chamber are given, notably for the method used to solve the drift chamber left/right ambiguity. The chambers are found to operate reliably and efficiently with very good spatial resolution, σ = ~200µm. The systematic artificial asymmetry in the polarimeter is also studied. Finally, scattering-efficiency and figure-of-merit ([formula omitted]) results are presented for 230 MeV protons scattering off a 7cm carbon analyzer in the three cases of ø + π and 2π azimuthal scattering acceptance symmetry, and full polarimeter acceptance. In particular, it is found that when employing the Besset weighted-sums polarization extraction technique, imposition of ø + π azimuthal scattering symmetry results in only a small increase in measured statistical error compared to results obtainable from a full Fourier spectrum analysis with no applied acceptance symmetry. Suggestions for improvements to established practices are offered throughout.

description: Background: Psychiatry is in urgent need of reliable biomarkers. Novel neuromelanin-sensitive magnetic resonance imaging (NM-MRI) sequences provide a time-efficient and non-invasive way to investigate the human brain in-vivo. This gives insight into the metabolites of dopaminergic signaling and may provide further evidence for potential dopaminergic alterations in patients with schizophrenia (SCZ). The present systematic review provides a meta-analysis of case-control studies using neuromelanin-sensitive sequences in SCZ vs. healthy controls (HC). Methods: According to predefined search terms and inclusion criteria studies were extracted on PubMed. Meta-analyses with a fixed and random-effects model with inverse variance method, DerSimonian-Laird estimator for tau(2), and Cohen's d were calculated. Bias was assessed using funnel plots. The primary study outcome was contrast-to-noise ratio (CNR) in the substantia nigra compared between HC and SCZ. Results: The total sample of k = 6 studies included n = 183 cases and n = 162 controls. Across all studies we found a significant elevation of CNR in the substantia nigra (d = 0.42 [0.187; 0.655], z = 3.521, p < 0.001) in cases compared to controls. We found no significant difference in the control region of locus coeruleus (d = -0.07 [-0.446; 0.302], z = -0.192, p = 0.847), with CNR for the latter only reported in k = 3 studies. Conclusion: CNR in the substantia nigra were significantly elevated in cases compared to controls. Our results support neuromelanin as a candidate biomarker for dopaminergic dysfunction in schizophrenia. Further studies need to assess this candidate marker in large, longitudinal cohorts and address potential effects of disease state, medication and correlations with symptoms.
Role of reversibility in viral capsid growth: A paradigm for self-assembly

description: Self-assembly at submicroscopic scales is an important but little understood phenomenon. A prominent example is virus capsid growth, whose underlying behavior can be modeled using simple particles that assemble into polyhedral shells. Molecular dynamics simulation of shell formation in the presence of an atomistic solvent provides new insight into the self-assembly mechanism, notably that growth proceeds via a cascade of strongly reversible steps and, despite the large variety of possible intermediates, only a small fraction of highly bonded forms appear on the pathway.

description: Objectives: The objective of this in vitro study was to assess the accuracy of fully guided implant placement following virtual implant planning based on MRI. Material and methods: Sixteen human cadaver hemimandibles with single missing teeth (n = 3), partially edentulous (n = 6) and edentulous situations (n = 7) were imaged using MRI. MRI and optical scans obtained with an intraoral scanner, were imported into an implant planning software. Virtual prosthetic and implant planning were performed regarding hard- and soft-tissue anatomy. Drill guides were manufactured, and fully guided implant placement was performed. Buccal and lingual bone and implant nerve distance were measured by three examiners in preoperative MRI and postoperative CBCT. The implant position was assessed using a software for deviation of implant positions displayed in CBCT and optical scans, respectively. Results: MRI displayed relevant structures for implant planning such as cortical and cancellous bone, inferior alveolar nerve and neighboring teeth. Implant planning, CAD/CAM of drill guides and guided implant placement were performed. Deviations between planned and actual implant positions in postoperative CBCT and optical scans were 1.34 mm (SD 0.84 mm) and 1.03 mm (SD 0.46 mm) at implant shoulder; 1.41 mm (SD 0.88 mm) and 1.28 mm (SD 0.52 mm) at implant apex, and 4.84° (SD 3.18°) and 4.21° (SD 2.01°). Measurements in preoperative MRI and postoperative CBCT confirmed the compliance with minimum distances of implants to anatomical structures. Conclusions: Relevant anatomical structures for imaging diagnostics in implant dentistry are displayed with MRI. The accuracy of MRI-based fully guided implant placement in vitro is comparable to the workflow using CBCT.

description: The accuracy of calculation of spectral line shapes in one-dimensional approximation is studied analytically in several limiting cases for arbitrary collision kernel and numerically in the rigid spheres model. It is shown that the deviation of the line profile is maximal in the center of the line in case of large perturber mass and intermediate values of collision frequency. For moderate masses of buffer molecules the error of one-dimensional approximation is found not to exceed 5%.

description: Background: The COVID-19 pandemic may lead to negative mental health effects but the effect on alcohol consumption among younger adults is unclear. We assess predictors of change in alcohol consumption during the first phase of the COVID-19 pandemic among younger adults. Methods: This cross-sectional internet-based survey was part of an overarching project, the Corona Drug Survey, which was conducted from April 30 to August 4, 2020. Participants of any sex and >= 18 years old were included. The primary outcome measure was change in alcohol consumption during the early COVID-19 pandemic. We implemented an ordinal logistic regression to assess the effect (odds ratio [OR] and 95% confidence interval [CI]) of the following predictors: quarantine restrictions on leaving the residence, number of individuals in the household, problematic alcohol consumption before the pandemic (CAGE [cutting down, annoyance by criticism, guilty feeling, and eye-opener] score), personal concern regarding the pandemic, age, and sex. Results: 3,321 participants with a mean age of 32 (SD: 13) years were included in this study. 70.4% of participants reported less or unchanged alcohol consumption in the recent 4 weeks of the pandemic compared to before the pandemic. A higher number of individuals in the household was associated with a reduced alcohol consumption (OR = 0.869; 95% CI = 0.815-0.927). No quarantine restrictions on leaving the residence (OR = 1.593; 95% CI = 1.397-1.817), a higher age (1.006; 1.001-1.011), and female sex (compared to males: 1.206; 1.062-1.371) were associated with an increase in alcohol consumption. The CAGE score before the pandemic (OR = 0.983; 95% CI = 0.931-1.037) and the pandemic concern (0.927; 0.857-1.003) were not associated with a significant change in alcohol consumption. Celebrations were no longer frequent drinking occasions during the pandemic compared to before the pandemic. The majority of participants (60.9%) did not use alcohol drinking as a coping mechanism to mitigate negative effects of the pandemic. Interpretation: In this cohort of younger adults with fewer celebratory drinking occasions, restrictions on leaving the residence and the number of persons in the household were the strongest predictors of reduced alcohol consumption during the early phase of the pandemic.

description: Σκοπός της διατριβής ήταν η μελέτη της επίδρασης της πίεσης στις φυσικές ιδιότητες υλικών με ισχυρή ηλεκτρονιακή σύζευξη, δηλαδή υλικών που περιέχουν ιόντα μεταβατικών μετάλλων. Πιο συγκεκριμένα, μελετήθηκαν οι δομικές, δονητικές και ηλεκτρονιακές ιδιότητες επτά ενώσεων μεταβατικών μετάλλων μέσω περίθλασης ακτίνων Χ, φασματοσκοπίας Raman και ανακλαστικότητας μέσου υπερύθρου υπό πίεση. Τα υλικά τα οποία μελετήθηκαν στην παρούσα διατριβή είναι οι περοβσκίτες ReO3 και LaTiO3, οι πυροχλωρίτες Cd2Re2O7 και Y2Mn2O7, ο σπινέλιος CdCr2S4, καθώς και οι ενώσεις σιδήρου BaFe2As2 και FeSe. Δεδομένου ότι τα κίνητρα πίσω από τις πειραματικές μας μελέτες είναι διαφορετικά για καθένα από αυτά τα υλικά, μου δόθηκε η ευκαιρία να ασχοληθώ και να επιλύσω πολλά και διαφορετικά πειραματικά προβλήματα, καθώς η χρήση της πίεσης ως μεταβλητή σε συνδυασμό με τις προαναφερθέντες πειραματικές τεχνικές επιτρέπουν την κατανόηση της συμμετοχής των δομικών ιδιοτήτων των μελετηθέντων υλικών σε σχέση με τις υπόλοιπες φυσικές τους ιδιότητες.
description: This thesis has been devoted on the effect of high pressure on the physical properties of selected correlated-electron systems, i.e. compounds which contain transition metal ions. Specifically, I have studied the structural, vibrational, and electronic properties of seven transition metal compounds by means of x-ray diffraction, Raman spectroscopy, and mid-infrared reflectivity, respectively, under pressure. The compounds that have been studied in this thesis consist of the ReO3 and LaTiO3 perovskites, the Y2Mn2O7 and Cd2Re2O7 pyrochlores, the CdCr2S4 spinel, as well as the layered BaFe2As2 and FeSe compounds. Since each of them poses a different problem with respect to its high-pressure behavior, I had the opportunity to look into several directions for the understanding and the interpretation of the observed pressure-induced effects. It is important to note here that using pressure as a variable, combined with the aforementioned experimental techniques and methods, can resolve the role of the structural properties with respect to the rest of the physical properties of the materials under study.

description: Exposure to childhood trauma is a well-known risk factor for severe mental disorders including schizophrenia and other non-affective psychoses. Beyond childhood trauma, there is increasing evidence that bullying, social exclusion, and discrimination during adolescence and adulthood may increase the risk of developing a psychotic disorder, and that such forms of traumatization may also underlie the elevated psychosis risk among migrants or persons with a visible minority status. In this umbrella review, we systematically assess meta-analyses regarding trauma and social adversity. A systematic literature review yielded 11 meta-analyses that met inclusion criteria and could be summarized quantitatively with a random effect model. Furthermore, six meta-analyses were evaluated qualitatively. Heterogeneity and publication bias were apparent in several meta-analyses. We observed that most significant social risk factors for psychosis were vulnerability for racist discrimination [OR = 3.90 (3.25-4.70)], migration [OR = 2.22 (1.75-2.80)], and childhood adversities [OR = 2.81 (2.03-3.83)]. Furthermore, social factors increasing the risk for psychosis were variation/impairment of parental communication, aversive adult life events, bullying, and factors associated with social isolation and discrimination. In spite of these environmental risk factors, there is a lack of evidence regarding treatment of trauma and psychosis, although some psychotherapeutic and art therapy approaches appear to be promising. Beyond individual interventions, stigmatization, racism, and other forms of discrimination need to be targeted to increase solidarity and communal support.

description: Frustration refers to competition between different interactions that cannot be simultaneously satisfied, a familiar feature in many magnetic solids. Strong frustration results in highly degenerate ground states, and a large suppression of ordering by fluctuations. Key challenges in frustrated magnetism are characterizing the fluctuating spin-liquid regime and determining the mechanism of eventual order at lower temperature. Here, we study a model of a diamond lattice antiferromagnet appropriate for numerous spinel materials. With sufficiently strong frustration a massive ground state degeneracy develops amongst spirals whose propagation wavevectors reside on a continuous two-dimensional ``spiral surface'' in momentum space. We argue that an important ordering mechanism is entropic splitting of the degenerate ground states, an elusive phenomena called order-by-disorder. A broad ``spiral spin-liquid'' regime emerges at higher temperatures, where the underlying spiral surface can be directly revealed via spin correlations. We discuss the agreement between these predictions and the well characterized spinel MnSc2S4.

description: The structural parameters of $ε$-FeGe have been determined at ambient conditions using single crystal refinement. Powder diffraction have been carried out to determine structural properties and compressibility for pressures up to 30 GPa and temperatures as low as 82 K. The discontinuous change in the pressure dependence of the shortest Fe-Ge interatomic distance might be interpreted as a symmetry-conserving transition and seems to be related to a magnetic phase boundary line.

description: In this review paper on pulsar wind nebulae (PWN) we discuss the properties of such nebulae within the context of containment against cross-field diffusion (versus normal advection), the effect of reverse shocks on the evolution of offset ``Vela-like'' PWN, constraints on maximum particle energetics, magnetic field strength estimates based on spectral and spatial properties, and the implication of such field estimates on the composition of the wind. A significant part of the discussion is based on the High Energy Stereoscopic System ({\it H.E.S.S.} or {\it HESS}) detection of the two evolved pulsar wind nebulae Vela X (cocoon) and HESS J1825-137. In the case of Vela X (cocoon) we also review evidence of a hadronic versus a leptonic interpretation, showing that a leptonic interpretation is favored for the {\it HESS} signal. The constraints discussed in this review paper sets a general framework for the interpretation of a number of offset, filled-center nebulae seen by {\it HESS}. These sources are found along the galactic plane with galactic latitudes $|b|\sim 0$, where significant amounts of molecular gas is found. In these regions, we find that the interstellar medium is inhomogeneous, which has an effect on the morphology of supernova shock expansion. One consequence of this effect is the formation of offset pulsar wind nebulae as observed.
