Constraints on the Cosmic-Ray Density Gradient beyond the Solar Circle from Fermi gamma-ray Observations of the Third Galactic Quadrant
Creators: name: Fermi LAT Collaboration

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: We report an analysis of the interstellar $γ$-ray emission in the third Galactic quadrant measured by the {Fermi} Large Area Telescope. The window encompassing the Galactic plane from longitude $210\arcdeg$ to $250\arcdeg$ has kinematically well-defined segments of the Local and the Perseus arms, suitable to study the cosmic-ray densities across the outer Galaxy. We measure no large gradient with Galactocentric distance of the $γ$-ray emissivities per interstellar H atom over the regions sampled in this study. The gradient depends, however, on the optical depth correction applied to derive the \HI\ column densities. No significant variations are found in the interstellar spectra in the outer Galaxy, indicating similar shapes of the cosmic-ray spectrum up to the Perseus arm for particles with GeV to tens of GeV energies. The emissivity as a function of Galactocentric radius does not show a large enhancement in the spiral arms with respect to the interarm region. The measured emissivity gradient is flatter than expectations based on a cosmic-ray propagation model using the radial distribution of supernova remnants and uniform diffusion properties. In this context, observations require a larger halo size and/or a flatter CR source distribution than usually assumed. The molecular mass calibrating ratio, $X_{\rm CO} = N({\rm H_{2}})/W_{\rm CO}$, is found to be $(2.08 \pm 0.11) \times 10^{20} {\rm cm^{-2} (K km s^{-1})^{-1}}$ in the Local-arm clouds and is not significantly sensitive to the choice of \HI\ spin temperature. No significant variations are found for clouds in the interarm region.

description: When coupling a superconductor to a normal conducting region the physical properties of the system are highly affected by the superconductor. We will investigate the effect of one or two superconductors on the conductance of a ballistic chaotic quantum dot to leading order in the total channel number using trajectory based semiclassics. The results show that the effect of one superconductor on the conductance is of the order of the number of channels and that the sign of the correction from the Drude conductance depends on the particular ratios of the numbers of channels of the superconducting and normal conducting leads. In the case of two superconductors with the same chemical potential we will also see how the conductance and the sign of quantum corrections are affected by their phase difference. As far as random matrix theory results exist these are reproduced by our calculations. Furthermore in the case that the chemical potential of the superconductors is the same as that of one of the two normal leads the conductance shows, under certain conditions, similar effects as a normal metal-superconductor junction. The semiclassical framework is also able to treat the thermopower of chaotic Andreev billiards consisting of one chaotic dot, two normal leads and two superconducting islands and shows it to be antisymmetric in the phase difference of the superconductors.

description: We analyze the distribution of heat generated in driven single-electron transitions and discuss the related non-equilibrium work theorems. In the adiabatic limit, the heat distribution is shown to become Gaussian, with the heat noise that, in spite of thermal fluctuations, vanishes together with the average dissipated energy. We show that the transitions satisfy Jarzynski equality for arbitrary drive and calculate the probability of the negative heat values. We also derive a general condition on the heat distribution that generalizes the Bochkov-Kuzovlev equality and connects it to the Jarzynski equality.

Developing a learning model for teaching film production online
Creators: name: Ziemsen, Eva
Publisher: name: University of British Columbia
Year: 2024

description: Through my roles as a film professor, filmmaker and PhD student, I have acquired a strong motivation to develop a learning model for the teaching of film production online. My initial interest for conducting research in this area began a few years ago when I taught a screenwriting workshop in Bhutan. On my return to Canada, I wished there was a way for me to continue teaching my students in Bhutan in the domain of film production. Further research has led me to discover that machinima, a virtual mode of recording animation, could be the solution to teaching almost all aspects of filmmaking, entirely online. Machinima is already very popular amongst educators, both face-to-face and as an online mode of delivery, however, its legitimacy as a cinematic art form has given rise to a controversial debate. My goal was to employ the research method of a/r/tography (standing for artist, researcher, and teacher), to create a complex artistic and academic work to demonstrate that machinima is a valid method of filmmaking and is an immersive mode of teaching film production in the online context. The Art entailed creating a short hybrid film using machinima and live action, entitled, Romeo & Juliette2016. The Research included a literature review that situated my work in the theory that underpins machinima as an art form and in the context of online learning. The Teacher component included a documentary in which I exhibited my film to select ‘critics’, in film, media and film education, and invited them to respond. The documentary was intended to produce discourse around the notion of machinima as an art form and as a teaching tool. Finally, in conclusion, I wrote a response chapter to this interaction and to the project as a whole. This study is highly relevant in the current landscape of media and 21st century education as virtual reality applications are taking hold in the professional filmmaking process and as a teaching tool, and machinima is part of this revolution.

Critical-doping universality for cuprate superconductors: Oxygen nuclear-magnetic-resonance investigation of Ca(x)La(1-x)Ba(1.75-x)La(0.25+x)Cu(3)O(y)

description: The critical doping levels in cuprates, where the ground state changes its nature (from an antiferromagnet to a spin glass to superconductor to metal), are not universal. We investigate the origin of these critical doping variations by measuring the in-plane oxygen $p_σ$ hole density in the CuO$_{2}$ layers as a function of the oxygen density $y$ in (Ca$_{x}$ La$_{1-x}$)(Ba$_{1.75-x}$La$_{0.25+x}$)Cu$_{3}$O$_{y}$. This is done using the oxygen 17 nuclear quadrupole resonance parameter $ν_{Q}$. We compare compounds with $x=0.1$ and 0.4 which have significant critical $y$ variations and find that these variations can be explained by a change in the efficiency of hole injection into the $p_σ$ orbital. This allows us to generate a unified phase diagram for the CLBLCO system across the entire doping range, with no adjustable parameters.

Assessment of ecosystem services and perceived benefits of street trees : a case study of Coyoacan, Mexico City
Creators: name: Navarro Perez De Leon, Nuria Monica
Publisher: name: University of British Columbia
Year: 2017

description: Mexico City, one of the biggest and most polluted cities in the world, is facing a gradual disappearance of its green areas, especially the loss of street trees. In the current situation, street trees are subject to constant removal, poor management and vandalism, and few studies have been done about their role and effectiveness in air pollution removal and carbon sequestration. For this study, the ecosystem services of street trees were quantified using the software i-Tree Eco along with a social survey of how people perceived them. The study site is Coyoacan, one of the greenest districts in Mexico City, comprised of 95 neighbourhoods, of which 12 were sampled. A random stratified sample was carried out to estimate the number of street trees in Coyoacan and the number of street units (blocks) to be sampled in each of the 12 neighbourhoods, in order to reach a sample size of 500 trees. The surveys were performed following a pass-by method. In general street trees provide important quantities of ecosystem services at the district level; but the predominance of small trees produces lower ecosystem service values compared to other cities with similar populations. The situation can be improved if the survival and healthy growth of those small trees can be guaranteed through better management practices. At the neighbourhood level we encountered an uneven distribution in the number of street trees and in the proportion of large trees over small trees, affecting the quantity of ecosystem services which a neighbourhood receives. These findings suggest that to increase the provision of ecosystem services at a city or district level, resources should be directed at a local level, looking to provide equality in the distribution of ecosystem services among neighbourhoods rather than allocating resources through random tree plantations across the city. Finally, people show high appreciation for trees and knowledge about a wide range of benefits, suggesting a tree caring culture that can be strengthened through social involvement programs for the care and management of street trees.

description: The transition temperature and the critical fields of electron-beam evaporated Nb/Gd/Nb triple layers and Nb/Gd multilayers have been determined by measurements of the electrical resistivity and the dc susceptibility. For constant thickness d(Gd) of the Gd layers, we observe a decrease of T(c) and H(c2 perpendicular-to) with decreasing thickness d(Nb) of Nb layers down to a critical thickness d(c), below which superconductivity is completely destroyed. The parallel critical fields mostly show the square-root temperature dependence near T(c), typical for two-dimensional superconductors. As predicted theoretically, competing pair-breaking mechanisms lead to a nonmonotonic dependence of H(c parallel-to) on d(Nb). We have also studied the dependence T(c)(d(Gd)) with constant d(Nb) and find a decrease of the T(c)(d(Gd)) curve with increasing d(Cd) and a steplike structure at d(Gd) almost-equal-to 20 angstrom. To clarify the nature of this step, the ferromagnetic transition of the Gd films is determined with the transverse magneto-optical Kerr effect. Long-range magnetic order is found only above d(Gd) almost-equal-to 20 angstrom, which is attributed to the formation of a discontinuous film below this thickness. These results indicate a change in the underlying pair-breaking mechanism.

description: The Dempster--Shafer (DS) theory is a powerful tool for probabilistic reasoning based on a formal calculus for combining evidence. DS theory has been widely used in computer science and engineering applications, but has yet to reach the statistical mainstream, perhaps because the DS belief functions do not satisfy long-run frequency properties. Recently, two of the authors proposed an extension of DS, called the weak belief (WB) approach, that can incorporate desirable frequency properties into the DS framework by systematically enlarging the focal elements. The present paper reviews and extends this WB approach. We present a general description of WB in the context of inferential models, its interplay with the DS calculus, and the maximal belief solution. New applications of the WB method in two high-dimensional hypothesis testing problems are given. Simulations show that the WB procedures, suitably calibrated, perform well compared to popular classical methods. Most importantly, the WB approach combines the probabilistic reasoning of DS with the desirable frequency properties of classical statistics.

Lowering the Characteristic Mass of Cluster Stars by Magnetic Fields and Outflow Feedback

description: Magnetic fields are generally expected to increase the characteristic mass of stars formed in stellar clusters, because they tend to increase the effective Jeans mass. We test this expectation using adaptive mesh refinement (AMR) magnetohydrodynamic simulations of cluster formation in turbulent magnetized clumps of molecular clouds, treating stars as accreting sink particles. We find that, contrary to the common expectation, a magnetic field of strength in the observed range decreases, rather than increases, the characteristic stellar mass. It (1) reduces the number of intermediate-mass stars that are formed through direct turbulent compression, because sub-regions of the clump with masses comparable to those of stars are typically magnetically subcritical and cannot be compressed directly into collapse, and (2) increases the number of low-mass stars that are produced from the fragmentation of dense filaments. The filaments result from mass accumulation along the field lines. In order to become magnetically supercritical and fragment, the filament must accumulate a large enough column density (proportional to the field strength), which yields a high volume density (and thus a small thermal Jeans mass) that is conducive to forming low-mass stars. We find, in addition, that the characteristic stellar mass is reduced further by outflow feedback. The conclusion is that both magnetic fields and outflow feedback are important in shaping the stellar initial mass function (IMF).

description: The transition temperature and the critical fields of e--beam evaporated Nb/Gd/Nb trilayers and Nb/Gd multilayers have been determined resistively and by dc-susceptibility. For constant thickness of the Gd layers we observe with decreasing thickness d(Nb)of Nb layers a decrease of T(c) and H(c2 perpendicular-to) down to a critical thickness d(c), below which superconductivity is completely destroyed. This is due to pair breaking by the exchange field within the ferromagnetic Gd layers. The parallel critical fields mostly show the square-root like temperature dependence near T(c) typical for 2D-superconductors. The interplay of orbital pair breaking by the external field and the exchange-field induced pair breaking leads to a nonmonotonic dependence of H(c parallel-to) on d(Nb) as predicted

description: Self-energies of a minimally coupled scalar field with quartic and trilinear interactions are calculated in a de Sitter background, using a position space propagator. For quartic interactions, we recover earlier results for the seagull diagram, namely that it contributes an effective mass for the scalar field at leading order in the infrared enhancement in a steady-state de Sitter background. We further show that the sunset diagram also contributes to this effective mass and argue that these two contributions are sufficient in order to determine a self-consistent dynamical mass. In addition, trilinear interactions also induce a dynamical mass for the scalar field which we calculate. Since an interacting scalar field in de Sitter acquires a dynamical mass through these loop corrections, the infrared divergences of the two-point correlator are naturally self-regulated.

description: The superconducting properties of amorphous W/Si multilayers are studied. A nearly linear increase of T(c) with increasing number of W/Si bilayers N is observed for N = 3 to 10. The parallel and perpendicular critical field data show strong interlayer coupling between the superconducting layers in a (1 nm Si/1 nm W) x 10 multilayer and weak coupling for a (5 nm Si/1 nm W) x 9 multilayer. The broadening of the resistive transition in perpendicular magnetic fields is analyzed within the frame of the thermally activated flux flow model. A temperature independent activation energy U is found for weakly coupled W/Si multilayers with a magnetic field dependence U approximately - 1n H.

description: Virtual presentation at the #ACSSPRING2025 meeting. Abstract:

“The #ACSFall2023 talk “Chemistry in Wikidata visualized with Scholia” gave an overview of the information about chemicals and metabolites in Wikidata, how Scholia was used to provide access to this knowledge, and how open source tools were used to support curation of the knowledge. This update will discuss updates in the chemistry in Wikidata (more external identifiers , more links to literature, more physicochemical data), how to use the increased linking between resources (e.g. how to use SPARQL to find lipids in natural product literature not listed in LIPID MAPS), and how provenance information can support your options to validate AI modelling approaches. This presentation will also introduce shape expressions for chemistry in Wikidata to support quality assurance and consistency. Furthermore, this work will also discuss how the open license (CCZero) and Application Programming Interfaces (APIs) of Wikidata allow data curation of external databases, reuse in custom datasets to enrich their content. Open source code example will document how these tasks are performed.“
Evolving federalism : intergovernmental relations and multilevel governance in Canada
Creators: name: Jessica, Weller
Publisher: name: University of British Columbia
Year: 2017

description: The following research paper investigates the changing character of federalism in Canada, as expressed through intergovernmental relations. Specifically, the impact that individual prime ministers and their governments may have on these relationships is explored. In particular, Stephen Harper and Justin Trudeau’s management styles are compared in order to determine what lasting or significant effect, if any, these individuals have had on how Canada’s federal and provincial governments interact with each other. Secondary literature describing and summarizing Harper’s style of open federalism, in conjunction with primary research on Justin Trudeau’s reversion to a more collaborative style, concludes that though each prime minister was able to have some tangible effects on federal-provincial relations during their time in office, these effects were, or will be, easily overridden by their successors. The following research asks whether Harper and Trudeau’s actual styles of intergovernmental relations were consistent with their rhetoric on the same subject. Though Harper spoke often about his preferred style of open federalism, it appears to many scholars that not all of his actions reflected the core tenets of this model. Likewise, though Trudeau advertised a collaborative, more multi-level approach to governance during the 2015 election campaign and during his time in office, I conclude that much of his efforts to follow up on these principles are symbolic at best. In both cases, it appears that the federal government consistently pursues its own goals, regardless of the rhetoric used to describe provincial involvement, rights, and in Trudeau’s case, genuine collaboration with both the provinces and additional third-party groups.

description: We report on a combined structural and electronic analysis of niobium ultrathin films (from 2 to 10 nm) deposited in ultra-high vacuum on atomically flat R-plane sapphire wafers. A textured polycrystalline morphology is observed for the thinnest films showing that hetero-epitaxy is not achieved under a thickness of 3.3nm, which almost coincides with the first measurement of a superconducting state. The superconducting critical temperature rise takes place on a very narrow thickness range, of the order of a single monolayer (ML). The thinnest superconducting sample (3 nm/9ML) has an offset critical temperature above 4.2K and can be processed by standard nanofabrication techniques to generate air- and time-stable superconducting nanostructures, useful for quantum devices.

Facilitating critical thinking and clinical judgment in clinical nursing education
Creators: name: Desrosiers, Sarah
Publisher: name: University of British Columbia
Year: 2017

description: Nurses who can critically think and make clinical judgments in the clinical setting are crucial to safe and effective nursing care. This type of critical thinking and clinical judgment is best developed during clinical education, which provides students with the opportunity to bridge the theory to practice gap. Clinical instructors guide students’ development of critical thinking and clinical judgment in the clinical setting. Despite clinical instructors having such a significant impact on critical thinking and clinical judgment there is limited research on how they facilitate students’ development of critical thinking and clinical judgment. This qualitative analysis explored how clinical instructors facilitate the development of critical thinking and clinical judgment of nursing students. This study used interpretive description to analyze interviews with eight clinical instructors to develop themes and subthemes within the data. These themes were discussed in relation to definitions of critical thinking and clinical judgment, indicators for evaluation, clinical teaching strategies, and contextual facilitators and barriers. Clinical instructors who took part in this study defined the concept of critical thinking as : The process that leads to clinical judgment, the decision. Evaluation was based on broad indicators of patient safety, effective communication, students’ confidence in their ability to critically think and make clinical decisions, and taking ownership of their patient care. Clinical instructors identified a variety of clinical teaching methods that they adapted and individualized to specific student needs. Clinical instructors also use multiple strategies to meet student needs, which they then adapt for each cohort. Contextual factors also impact students’ development of critical thinking and clinical judgment such as buddy nurses, the school of nursing curriculum, clinical ]instructors, and the nursing student themselves. This study identified suggestions for curriculum development, clinical instructor development, and potential areas for future research in relation to clinical education. Clinical instructors are key components of nursing education and the development of critical thinking and clinical judgment in nursing students; as such, it is important to understand their perspectives on how they develop these student abilities.

description: We reconsider quantum gravitational threshold effects to the unification of fermion masses in Grand Unified Theories. We show that the running of the Planck mass can have a sizable effect on these thresholds which are thus much more important than naively expected. These corrections make any extrapolation from low energy measurements challenging.

Regulation of Star Formation Rates in Multiphase Galactic Disks: a Thermal/Dynamical Equilibrium Model

description: We develop a model for regulation of galactic star formation rates Sigma_SFR in disk galaxies, in which ISM heating by stellar UV plays a key role. By requiring simultaneous thermal and (vertical) dynamical equilibrium in the diffuse gas, and star formation at a rate proportional to the mass of the self-gravitating component, we obtain a prediction for Sigma_SFR as a function of the total gaseous surface density Sigma and the density of stars + dark matter, rho_sd. The physical basis of this relationship is that thermal pressure in the diffuse ISM, which is proportional to the UV heating rate and therefore to Sigma_SFR, must adjust to match the midplane pressure set by the vertical gravitational field. Our model applies to regions where Sigma < 100 Msun/pc^2. In low-Sigma_SFR (outer-galaxy) regions where diffuse gas dominates, the theory predicts Sigma_SFR \propto Sigma (rho_sd)^1/2. The decrease of thermal equilibrium pressure when Sigma_SFR is low implies, consistent with observations, that star formation can extend (with declining efficiency) to large radii in galaxies, rather than having a sharp cutoff. The main parameters entering our model are the ratio of thermal pressure to total pressure in the diffuse ISM, the fraction of diffuse gas that is in the warm phase, and the star formation timescale in self-gravitating clouds; all of these are (in principle) direct observables. At low surface density, our model depends on the ratio of the mean midplane FUV intensity (or thermal pressure in the diffuse gas) to the star formation rate, which we set based on Solar neighborhood values. We compare our results to recent observations, showing good agreement overall for azimuthally-averaged data in a set of spiral galaxies. For the large flocculent spiral galaxies NGC 7331 and NGC 5055, the correspondence between theory and observation is remarkably close.

description: We propose a generic design for Chinese remainder algorithms. A Chinese remainder computation consists in reconstructing an integer value from its residues modulo non coprime integers. We also propose an efficient linear data structure, a radix ladder, for the intermediate storage and computations. Our design is structured into three main modules: a black box residue computation in charge of computing each residue; a Chinese remaindering controller in charge of launching the computation and of the termination decision; an integer builder in charge of the reconstruction computation. We then show that this design enables many different forms of Chinese remaindering (e.g. deterministic, early terminated, distributed, etc.), easy comparisons between these forms and e.g. user-transparent parallelism at different parallel grains.

description: Sugar melts or solvent-free systems have been used to react simple unprotected hexoses at the C-1 atom with urea and urea derivatives to sugar-ureides by acid catalysis and with short reaction times. In one step, β-D-glucosyl- and β-D-mannosyl urea 2a/b were obtained in high yields. D-Galactose 6, N-acetyl-D-glucosamine 7, L-rhamnose 8 and 2-deoxy-D-glucose 9 were converted likewise to glycosyl ureas. Additionally, urea-related nucleophiles were investigated as melt components. N,N′-Ethylene urea 15, N,N′-allylurea 16 and ethyl carbamate 18 were β-selectively converted with D-glucose in good yield, giving the corresponding N-glycosides. Under these conditions, however, the condensation product with N-octylurea 17 was not accessible.

description: The physics of the initial conditions of heavy ion collisions is dominated by the nonlinear gluonic interactions of QCD. These lead to the concepts of parton saturation and the Color Glass Condensate (CGC). We discuss recent progress in calculating multi-gluon correlations in this framework, prompted by the observation that these correlations are in fact easier to compute in a dense system (nucleus-nucleus) than a dilute one (proton-proton).
