description: We derive a stationary and axisymmetric black hole solution to quadratic order in the spin angular momentum. The previously found, linear-in-spin terms modify the odd-parity sector of the metric, while the new corrections appear in the even-parity sector. These corrections modify the quadrupole moment, as well as the (coordinate-dependent) location of the event horizon and the ergoregion. Although the linear-in-spin metric is of Petrov type D, the quadratic order terms render it of type I. The metric does not possess a second-order Killing tensor or a Carter-like constant. The new metric does not possess closed timelike curves or spacetime regions that violate causality outside of the event horizon. The new, even-parity modifications to the Kerr metric decay less rapidly at spatial infinity than the leading-order in spin, odd-parity ones, and thus, the former are more important when considering black holes that are rotating moderately fast. We calculate the modifications to the Hamiltonian, binding energy and Kepler's third law. These modifications are crucial for the construction of gravitational wave templates for black hole binaries, which will enter at second post-Newtonian order, just like dissipative modifications found previously.

description: Since urban structure indicators influence travel behaviour, they have been widely studied. The goal of these studies was identifying effective factors to have sustainable transport patterns. However, investigating these factors has been problematic and the results are not reliable enough to be used universally. There are two main reasons for this: firstly, because socio-economic indicators impact neighbourhoods with comparable design differently; and secondly, factors such as income, and age, as well as self-selection factors are not easy to be evaluated. This paper addresses challenges and practices in this area to propose new objectives for further studies that cover previous shortcomings.

description: We present a determination of parton distribution functions (ABM11) and the strong coupling constant alpha_s at next-to-leading order and next-to-next-to-leading order (NNLO) in QCD based on world data for deep-inelastic scattering and fixed-target data for the Drell-Yan process. The analysis is performed in the fixed-flavor number scheme for n_f=3,4,5 and uses the MSbar-scheme for alpha_s and the heavy-quark masses. At NNLO we obtain the value alpha_s(M_Z) = 0.1134 +- 0.0011. The fit results are used to compute benchmark cross sections at hadron colliders to NNLO accuracy and to compare to data from the LHC.

description: We present the discovery of PTF 10vgv, a Type Ic supernova detected by the Palomar Transient Factory, using the Palomar 48-inch telescope (P48). R-band observations of the PTF 10vgv field with P48 probe the supernova emission from its very early phases (about two weeks before R-band maximum), and set limits on its flux in the week prior to the discovery. Our sensitive upper limits and early detections constrain the post-shock-breakout luminosity of this event. Via comparison to numerical (analytical) models, we derive an upper-limit of R \lesssim 4.5 Rsun (R \lesssim 1 Rsun) on the radius of the progenitor star, a direct indication in favor of a compact Wolf-Rayet star. Applying a similar analysis to the historical observations of SN 1994I, yields R \lesssim 1/4 Rsun for the progenitor radius of this supernova.

description: We study magnetic phases of two-component mixtures of ultracold fermions with repulsive interactions in optical lattices in the presence of hopping imbalance. Our analysis is based on dynamical mean-field theory (DMFT) and its real-space generalization at finite temperature. We study the temperature dependence of the transition into the ordered state as a function of the interaction strength and the imbalance parameter in two and three spatial dimensions. We show that below the critical temperature for Néel order mass-imbalanced mixtures also exhibit a charge-density wave, which provides a directly observable signature of the ordered state. For the trapped system, we compare our results obtained by real-space DMFT to a local-density approximation. We calculate the entropy for a wide range of parameters and identify regions, in which mass-imbalanced mixtures could have clear advantages over balanced ones for the purpose of obtaining and detecting quantum magnetism.

Tracing Outflows and Accretion: A Bimodal Azimuthal Dependence of MgII Absorption

description: We report a bimodality in the azimuthal angle distribution of gas around galaxies as traced by MgII absorption: Halo gas prefers to exist near the projected galaxy major and minor axes. The bimodality is demonstrated by computing the mean azimuthal angle probability distribution function using 88 spectroscopically confirmed MgII absorption-selected galaxies [W_r(2796)>0.1A] and 35 spectroscopically confirmed non-absorbing galaxies [W_r(2796)<0.1A] imaged with HST and SDSS. The azimuthal angle distribution for non-absorbers is flat, indicating no azimuthal preference for gas characterized by W_r(2796)<0.1A. We find that blue star-forming galaxies clearly drive the bimodality while red passive galaxies may exhibit an excess along their major axis. These results are consistent with galaxy evolution scenarios where star-forming galaxies accrete new gas, forming new stars and producing winds, while red galaxies exist passively due to reduced gas reservoirs. We further compute an azimuthal angle dependent MgII absorption covering fraction, which is enhanced by as much as 20-30% along the major and minor axes. The W_r(2796) distribution for gas along the major axis is likely skewed toward weaker MgII absorption than for gas along the projected minor axis. These combined results are highly suggestive that the bimodality is driven by gas accreted along the galaxy major axis and outflowing along the galaxy minor axis. Adopting these assumptions, we find that the opening angle of outflows and inflows to be 100 degrees and 40 degrees, respectively. We find the probability of detecting outflows is ~60%, implying that winds are more commonly observed.

Education, beliefs, and experiences : examining the role of parents in children's extracurricular activity participation
Creators: name: Ashbourne, Dianne
Publisher: name: University of British Columbia
Year: 2013

description: Several studies have suggested that extracurricular activity participation provides children with numerous benefits including higher academic achievement. Unfortunately, participation differences among Canadian children mean that not all children have equal access to these benefits. Understanding the role parents play in their children’s extracurricular activity participation will broaden understandings of participation differences among Canadian children and thus, will have important implications for mitigating inequality in the Canadian public school system. This study asks the following: what role do the beliefs, experiences, and education of parents play in determining whether their children participate in specialized athletics, music, language and leadership programs? Data used in this study were from the Paths on Life’s Way project at UBC; a longitudinal study of the graduating class of 1988 in British Columbia, Canada. Data were collected using postal surveys and face-to-face interviews. A mixed method approach utilizing sequential analysis procedures was employed. Interview data was used to guide the analysis of the survey data. Results suggest that both parental experience and parental beliefs play a role in school-age children’s participation in specialized athletics, music, language, and leadership programs to varying extents. Parents’ activity-specific beliefs are a particularly important determinant of children’s participation in extracurricular activities. Parental experience with extracurricular activities during high school are more significantly correlated with children’s extracurricular activity participation than current experiences, this highlights both the important role played by habitus and the complexity of the transfer of cultural capital between parents and their children. These relationships are stronger for parents with lower levels of educational attainment in nearly all cases except that of children’s participation in specialized language programs.
Forward modeling of emission in SDO/AIA passbands from dynamic 3D simulations

description: It is typically assumed that emission in the passbands of the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) is dominated by single or several strong lines from ions that under equilibrium conditions are formed in a narrow range of temperatures. However, most SDO/AIA channels also contain contributions from lines of ions that have formation temperatures that are significantly different from the "dominant" ion(s). We investigate the importance of these lines by forward modeling the emission in the SDO/AIA channels with 3D radiative MHD simulations of a model that spans the upper layer of the convection zone to the low corona. The model is highly dynamic. In addition, we pump a steadily increasing magnetic flux into the corona, in order to increase the coronal temperature through the dissipation of magnetic stresses. As a consequence, the model covers different ranges of coronal temperatures as time progresses. The model covers coronal temperatures that are representative of plasma conditions in coronal holes and quiet sun. The 131, 171, and 304 Å AIA passbands are found to be least influenced by the so-called "non-dominant" ions, and the emission observed in these channels comes mostly from plasma at temperatures near the formation temperature of the dominant ion(s). On the other hand, the other channels are strongly influenced by the non-dominant ions, and therefore significant emission in these channels comes from plasma at temperatures that are different from the "canonical" values. We have also studied the influence of non-dominant ions on the AIA passbands when different element abundances are assumed (photospheric and coronal), and when the effects of the electron density on the contribution function are taken into account.

description: We prove $L^q$ bounds on the restriction of spectral clusters to submanifolds in Riemannian manifolds equipped with metrics of $C^{1,α}$ regularity for $0 \leq α\leq 1$. Our results allow for Lipschitz regularity when $α=0$, meaning they give estimates on manifolds with boundary. When $0< α\leq 1$, the scalar second fundamental form for a codimension 1 submanifold can be defined, and we show improved estimates when this form is negative definite. This extends results of Burq-Gérard-Tzvetkov and Hu to manifolds with low regularity metrics.

description: We compute the effective coupling of the Majoron to W bosons at $\cO(\hbar)$ by evaluating the matrix element of the (B-L) current between the vacuum and a $W^+W^-$ state. The (B-L) anomaly vanishes, but the amplitude does not vanish as a result of a UV finite and non-local contribution which is entirely due to the mixing between left-chiral and right-chiral neutrinos. The result shows how anomaly-like couplings may arise in spite of the fact that the (B-L) current remains exactly conserved to all orders in $\hbar$, lending additional support to our previous proposal to identify the Majoron with the axion.

Executive function deficits in bipolar I disorder : association with brain structure, illness progression, and antipsychotic medication
Creators: name: Kozicky, Jan-Marie Elena
Publisher: name: University of British Columbia
Year: 2013

description: Executive function impairments are a core feature of Bipolar I Disorder (BDI), present not only during acute episodes but also persisting following remission of mood symptoms. Despite advances in knowledge regarding the neural basis of executive functions (EF) in healthy subjects, particularly in regards to the role of the dorsolateral prefrontal cortex (DLPFC) and caudate; research into how changes within these regions contribute to the deficits in BDI is lacking. This thesis explores EF in patients early in the course of illness, examining how impairments evolve with illness progression and how this may relate to neuromorphological changes and naturalistic pharmacological treatment regimes. The first analysis demonstrates that EF is moderate-severely impaired in patients with BDI even following sustained symptomatic recovery from their first manic episode. Both larger caudate size and treatment with a higher relative dose of an antipsychotic drug predicted the severity of deficits. Despite receiving ongoing clinical care, half of patients experienced a subsequent hypo/manic and/or depressive episode within one year. While those who remained well did show significant improvements in EF compared to those whose illness progressed, both patient groups still maintained moderate deficits compared to healthy subjects at follow-up. Although not directly associated with cognitive changes, sustained recovery during this time was also associated with reduced grey matter loss (including the left DLPFC) when compared affective recurrence, even after accounting for other clinical or treatment factors. Maintenance pharmacological treatment with an antipsychotic is commonly used to prevent episode recurrence in BDI. Drugs within this class each show varying affinity to the dopamine D₂ receptor (D₂R), which plays an important modulatory role in DLPFC and caudate function. Differences in D₂R binding have a likely impact on EF, as patients receiving an antipsychotic with high D₂R affinity (risperidone) showed larger impairments when compared to those treated with a low affinity drug (quetiapine) or no antipsychotic. These results demonstrate that illness related structural changes in the DLPFC and caudate are associated with the presence and evolution of executive function deficits in BDI; although the potential confounding effects of antipsychotics which influence functioning in these regions must also be considered.

description: Observations of high energy gamma rays recently revealed a persistent source in spatial coincidence with the binary system Eta Carinae. Since modulation of the observed gamma-ray flux on orbital time scales has not been reported so far, an unambiguous identification was hitherto not possible. Particularly the observations made by the Fermi Large Area Telescope (LAT) posed additional questions regarding the actual emission scenario owing to the existence of two energetically distinct components in the gamma-ray spectrum of this source, best described by an exponentially cutoff power-law function (CPL) at energies below 10 GeV and a power-law (PL) component dominant at higher energies. The increased exposure in conjunction with the improved instrumental response functions of the LAT now allow us to perform a more detailed investigation of location, spectral shape, and flux time history of the observed gamma-ray emission. For the first time, we are able to report a weak but regular flux decrease over time. This can be understood and interpreted in a colliding-wind binary scenario for orbital modulation of the gamma-ray emission. We find the spectral shape of the gamma-ray signal in agreement with a single emitting particle population in combination with significant absorption by gamma-gamma pair production. Studying the correlation of the flux decrease with the orbital separation of the binary components allows us to predict the behaviour up to the next periastron passage in 2014.

description: Recently, the use of carbon fibre reinforced polymer (CFRP) composites is predominant and will grow further. Although these fibrous composites are often manufactured near net shape, their mechanical machining is often required to meet dimensional tolerances. Considering the difficult-to-cut nature of CFRP composites, the technology planning of edge trimming of CFRPs poses significant challenges and obstacles. Therefore, the main aim of this study is to critically review and discuss challenges, recent expertise and experience gained in the area of edge trimming CFRPs. On the one hand, conventional and advanced edge trimming technologies are reviewed and compared. On the other hand, advanced cutting tools are presented and discussed. Finally, future scope and prospects are highlighted to determine further research scopes in the edge trimming of CFRP composites.

description: Those galaxy clusters which do not belong to the superclusters are referred to as the isolated clusters. Their relative abundance at a given epoch may be a powerful constraint of the dark energy equation of state since it depends strongly on how fast the structures grow on the largest scale in the Universe. We note that the mass function of the isolated clusters can be separately evaluated through the modification of the recently developed Corasaniti-Achitouv (CA) theory according to which the stochastic collapse barrier is quantified by two coefficients: the drifting average coefficient (β) and the diffusion coefficient (D_B). Regarding $β$ in the CA formalism as an adjustable parameter and assuming that the formation of isolated clusters corresponds to the case of D_B=0, we determine the mass function of the isolated clusters by fitting the numerical results from the MICE simulations to the modified CA formula. It is found that the best-fit value of beta changes with redshift and that the CA mass function with D_B=0 agrees very well with the numerical results at various redshifts. Defining the relative abundance of the isolated clusters, xi_I, as the ratio of the cumulative mass function of the isolated clusters to that of the non-isolated clusters at a given epoch, we finally show how sensitively xi_I changes with the dark energy equation of state. It is also discussed how xi_I can help to break the degeneracy between the dark energy equation of state and the other key cosmological parameters.

description: Der Begriff der Medienkompetenz und die damit verbundene Förderung dieser bei Lehramtsstudierenden, angehenden Lehrer:innen im Vorbereitungsdienst, wie auch ausgebildeten Lehrpersonen steht seit längerem im Zentrum der Lehrer:innenbildung. Hierbei können Medienkompetenzmodelle helfen, die medienbezogenen und medienpädagogischen Fertigkeiten und Fähigkeiten innerhalb der Lehrkräfteaus- und -weiterbildung zu strukturieren und analytisch aufzugreifen, um sie gezielt einzuordnen und zu fördern. Besonders in der beruflichen Lehrer:innenbildung gilt es diese Medienkompetenzen zu fördern, um die Lehrkräfte von morgen fachgerecht und medienpädagogisch auf die Transformationsprozesse und Veränderungen durch die zunehmende Digitalisierung vorzubereiten, die besonders in den beruflichen Bereichen Einzug erhalten. Dabei lassen sich Medienkompetenzmodelle in verschiedene Arten und vielerlei Taxonomien unterscheiden, die zu einer solchen Förderung hinzugezogen werden können und in diesem Beitrag aus aktueller und zukünftiger Perspektive der beruflichen Lehrer:innenbildung verstärkt betrachtet werden.
"Unborn and unbegot" : Richard III, Edward II, Richard II, and queer history

description: In my thesis, I treat Shakespeare’s Richard III, Marlowe’s Edward II, and Shakespeare’s Richard II as a queer sequence of history plays, or a kind of co-authored triptych, by reading their influences on each other and focusing on the iterative elements of their writing of history. I describe in my thesis how the queer affects, desires, and pleasures in these plays are integral to a History – the shared knowledge and impressions of a British national past – from which they are and have been systematically excluded.

description: Im Rahmen des Beitrags werden ausgewählte Ergebnisse des Projektes Leibniz works 4.0 – Veränderte Lern- und Arbeitswelten in der beruflichen Lehrerbildung dargestellt, welches von März 2020 bis Dezember 2023 durch das Bundesministerium für Bildung und Forschung (BMBF) gefördert wurde. Im Beitrag wird der Forschungsfrage nachgegangen, inwiefern individualisierte und flexibilisierte Lehr-Lernstrukturen dazu beitragen können, die Futures Literacy der Lehrkräfte für berufsbildende Schulen zu fördern. Dazu wird zuerst die Ausgangslage der zunehmenden Digitalisierung und des Lehrkräftemangels als Herausforderung der beruflichen Bildung dargelegt, welche die Grundlage der Projektziele bildet. Mit einem Blick auf die heterogene Studierendengruppe des Lehramts an berufsbildenden Schulen (LbS) werden anschließend ausgewählte Projektergebnisse, insbesondere die Lernplattform „Plattform für das Lehramt an berufsbildenden Schulen“ (plabs), und die dazugehörigen Evaluationsergebnisse aus den Jahren 2020, 2021 und 2023 vorgestellt. In der abschließenden Diskussion widmet sich der Beitrag den flexibilisierten Studienstrukturen durch Digitalisierung, der Selbstorganisationsdisposition und Innovationskompetenz der (angehenden) Lehrpersonen des LbS als Zukunftsgestaltungskompetenzen und schließt mit den Limitationen und einem Ausblick auf zukünftige Entwicklungen ab.

description: Tidal stripping of dark matter from subhalos falling into the Milky Way produces narrow, cold tidal streams as well as more spatially extended "debris flows" in the form of shells, sheets, and plumes. Here we focus on the debris flow in the Via Lactea II simulation, and show that this incompletely phase-mixed material exhibits distinctive high velocity behavior. Unlike tidal streams, which may not necessarily intersect the Earth's location, debris flow is spatially uniform at 8 kpc and thus guaranteed to be present in the dark matter flux incident on direct detection experiments. At Earth-frame speeds greater than 450 km/s, debris flow comprises more than half of the dark matter at the Sun's location, and up to 80% at even higher speeds. Therefore, debris flow is most important for experiments that are particularly sensitive to the high speed tail of the dark matter distribution, such as searches for light or inelastic dark matter or experiments with directional sensitivity. We show that debris flow yields a distinctive recoil energy spectrum and a broadening of the distribution of incidence direction.

A subset solution to the sign problem in random matrix simulations

description: We present a solution to the sign problem in dynamical random matrix simulations of a two-matrix model at nonzero chemical potential. The sign problem, caused by the complex fermion determinants, is solved by gathering the matrices into subsets, whose sums of determinants are real and positive even though their cardinality only grows linearly with the matrix size. A detailed proof of this positivity theorem is given for an arbitrary number of fermion flavors. We performed importance sampling Monte Carlo simulations to compute the chiral condensate and the quark number density for varying chemical potential and volume. The statistical errors on the results only show a mild dependence on the matrix size and chemical potential, which confirms the absence of sign problem in the subset method. This strongly contrasts with the exponential growth of the statistical error in standard reweighting methods, which was also analyzed quantitatively using the subset method. Finally, we show how the method elegantly resolves the Silver Blaze puzzle in the microscopic limit of the matrix model, where it is equivalent to QCD.
