description: In this paper a novel approach for the registration and segmentation of dynamic contrast enhanced renal MR images is presented. This integrated method is motivated by the observation of the reciprocity between registration and segmentation in 4D time-series images. Fully automated Fourier-based registration with sub-voxel accuracy and semi-automated time-series segmentation were intertwined to improve the accuracy in a multi-step fashion. We have tested our algorithm on several real patient data sets. Clinical validation showed remarkable and consistent agreement between the proposed method and manual segmentation by experts.

Creators: name: Sun, Baihua
Publisher: name: UNSPECIFIED

description: Pneumatische Stellventile werden heutzutage wegen ihrer hohen Stellgeschwindigkeiten und wirtschaftlichen Effizienz in der Prozessindustrie immer noch häufig eingesetzt. Für eine hohe Regelgüte der Prozesse sind zufriedenstellende Stellverhalten der Stellventile Voraussetzung. Hierfür ist die Auslegung des Ventil-Hook-Ups von zentraler Bedeutung. Das Ventil-Hook-Up beschreibt die Auswahl und die Verschaltung der pneumatischen Anbaugeräte (u. a. Stellungsregler, Booster, Druckregler und Rohrverbindungen). In der vorliegenden Arbeit wird eine modellbasierte Systemoptimierung der pneumatischen Stellventilen vorgestellt. Hierzu wird vor allem ein Simulationsmodell entwickelt, welches das Stellverhalten eines Stellventils präzise simuliert. Auf dieser Basis erfolgt eine Systemoptimierung des Ventil-Hook-Ups mit den zwei heuristischen Verfahren, „Genetische Algorithmen“ und „Tabu-Suche“. Bei der Implementierung werden die beiden Verfahren problemspezifisch gestaltet und ggf. modifiziert, um die Effizienz der Optimierung zu erhöhen. Damit liegt die erzielte Lösung möglichst nahe am globalen Optimum. Im Hinblick auf die Qualität der erzielten Lösung und den dazu erforderlichen Ressourcenaufwand erweist sich die modifizierte Tabu-Suche als am besten geeignetes Verfahren. Zum Schluss wird die zusätzliche Frage behandelt, wie die Prozessströmung das Stellverhalten eines Stellventils beeinflusst und wie negative Strömungseinflüsse im Bedarfsfall verringert werden können.
Spring and summer phytoplankton community dynamics and comparison of FRRF- and ¹³C-derived measurements of primary productivity in Rivers Inlet, British Columbia
Creators: name: Shiller, Victoria Jade
Publisher: name: University of British Columbia

description: Spring and summer phytoplankton community dynamics were monitored in the temperate coastal fjord, Rivers Inlet, British Columbia, to understand their impact on the growth of juvenile sockeye salmon. Spatial patterns in timing and magnitude of the diatom-dominated spring bloom appeared to be controlled by differences in mixing and stratification. At the sheltered head of the inlet, riverine input stratified the water column, the phytoplankton bloom appeared earlier and more intense. At the well-mixed mouth, where currents diluted the phytoplankton seed population, the bloom appeared delayed and reduced in intensity. The spring bloom was terminated by nitrate depletion except where salinity was low and phosphate became limiting due to oligotrophic freshwater input. While the spring community was diatom-dominated, the summer community was more diverse, with increased abundance of flagellates and ciliates. Primary productivity measurements using fast repetition rate fluorometry (FRRF) correlated well (~1:1) with estimates derived from 2-hour ¹³C-uptake incubations when phytoplankton were healthy in the lab. In contrast, under high light or low nutrient conditions, FRRF underestimates primary productivity. Community composition may also influence FRRF estimates of primary productivity. We calculated annual FRRF-derived primary productivity of 550 – 1100 g C · m⁻² · yr⁻¹. Potential sockeye production was estimated using primary productivity estimates derived from our ¹³C data. These calculations suggest that the sockeye carrying capacity of the fjord and lake are well matched and that current levels of primary production could support the ~10-fold higher historical sockeye returns. This implies that contemporary and historical levels of primary production are similar and are not the cause of the sockeye decline. More likely, a timing mismatch between trophic levels is negatively impacting sockeye smolts. Our results suggest that future sockeye production in Rivers Inlet may be negatively impacted by increased freshwater input and stratification, both of which may be influenced by climate warming. This physical forcing may precipitate a shift to a flagellate-dominated phytoplankton community, a longer food chain, and reduced energy transfer to smolts. Continued monitoring of phytoplankton dynamics is critical for refining predictions of ecosystem change and facilitating improvements in sockeye stock management policies.

description: We present two large cosmological N-body simulations, called Horizon Run 2 (HR2) and Horizon Run 3 (HR3), made using 6000^3 = 216 billions and 7210^3 = 374 billion particles, spanning a volume of (7.200 Gpc/h)^3 and (10.815 Gpc/h)^3, respectively. These simulations improve on our previous Horizon Run 1 (HR1) up to a factor of 4.4 in volume, and range from 2600 to over 8800 times the volume of the Millennium Run. In addition, they achieve a considerably finer mass resolution, down to 1.25x10^11 M_sun/h, allowing to resolve galaxy-size halos with mean particle separations of 1.2 Mpc/h and 1.5 Mpc/h, respectively. We have measured the power spectrum, correlation function, mass function and basic halo properties with percent level accuracy, and verified that they correctly reproduce the LCDM theoretical expectations, in excellent agreement with linear perturbation theory. Our unprecedentedly large-volume N-body simulations can be used for a variety of studies in cosmology and astrophysics, ranging from large-scale structure topology, baryon acoustic oscillations, dark energy and the characterization of the expansion history of the Universe, till galaxy formation science - in connection with the new SDSS-III. To this end, we made a total of 35 all-sky mock surveys along the past light cone out to z=0.7 (8 from the HR2 and 27 from the HR3), to simulate the BOSS geometry. The simulations and mock surveys are already publicly available at http://astro.kias.re.kr/Horizon-Run23/.

description: Materials design based on density functional theory (DFT) calculations is an emergent field of great potential to accelerate the development and employment of novel materials. Magnetic materials play an essential role in green energy applications as they provide efficient ways of harvesting, converting, and utilizing energy. In this review, after a brief introduction to the major functionalities of magnetic materials, we demonstrated how the fundamental properties can be tackled via high-throughput DFT calculations, with a particular focus on the current challenges and feasible solutions. Successful case studies are summarized on several classes of magnetic materials, followed by bird-view perspectives.
Painted landscapes from another age: what the Vasari’s frescoes in Palazzo Vecchio, Florence, tell abouturban fortifications

description: Palazzo Vecchio is a cultural-historical centre full of elements from different periods able to offer multiple ideas and reflections. Inside there are objects, rooms and environments that document many years of history interacting with many other realities and contexts. The “Hall of the 500”, the large audience hall restored by Giorgio Vasari commissioned by the grand duke Cosimo I, shows in its sumptuous wall paintings the views of cities, places and landscapes, captured in scenes of war and siege. It is possible to observe the city walls of Pisa, the Towers of Siena and Livorno, the military fortifications of Porto Ercole and San Vincenzo, the Mediterranean coasts and the inland valleys. Different places, conquered by the Medici family, which branch off throughout Tuscany and characterize the territory. These places today appear transformed and modified, in part or not, in the landscape and urban fabric. In some cases, it is still possible to find the remains of the sixteenth-century defensive buildings, while in others there is no longer any trace, or at most only few remains. Instead, they are legible in the paintings that identify their elements and characteristics. The opportunity arises for a comparison between real and painted architecture. From this point of view, the frescoes in the hall not only have value as artistic works but also as historical sources and documents able to tell through painting the conformation of the sites represented with well-defined details and historical reliability. Comparing the paintings with today's urban and landscape fabric, analogies and discrepancies appear, present, missing and added objects that allow to reconstruct the analyzed structures, and also to catalogue them according to the level of knowledge acquired with a good degree of reliability of the source. With these assumptions it was possible to model the painted defensive structures in 3D, using not only the frescoes but also writings, drawings and archive plans and also to catalogue it. A map was then edited to identify the level of knowledge achieved with each model. The aim is to increase knowledge of historical and cultural structures to enhance the city's cultural heritage.

description: We consider the chiral Lagrangian with a nonet of Goldstone bosons and a nonet of light vector mesons. The mixing between the pseudoscalar mesons eta and eta-prime is taken into account. A novel counting scheme is suggested that is based on hadrogenesis, which conjectures a mass gap in the meson spectrum of QCD in the limit of a large number of colors. Such a mass gap would justify to consider the vector mesons and the eta-prime meson as light degrees of freedom. The complete leading order Lagrangian is constructed and discussed. As a first application it is tested against electromagnetic transitions of light vector mesons to pseudoscalar mesons. Our parameters are determined by the experimental data on photon decays of the omega, phi and eta-prime meson. In terms of such parameters we predict the corresponding decays into virtual photons with either dielectrons or dimuons in the final state.

description: An approximate method to quantify the magnitude of the two-nucleon (2N) and three-nucleon (3N) short-range correlations (SRC) and their mass dependence is proposed. The proposed method relies on the concept of the "universality" or "local nuclear character" of the SRC. We quantify the SRC by computing the number of independent-particle model (IPM) nucleon pairs and triples which reveal beyond-mean-field behavior. It is argued that those can be identified by counting the number of nucleon pairs and triples in a zero relative orbital momentum state. A method to determine the quantum numbers of pairs and triples in an arbitrary mean-field basis is outlined. The mass dependence of the 2N and 3N SRC is studied. The predictions are compared to measurements. This includes the ratio of the inclusive inelastic electron scattering cross sections of nuclei to 2H and 3He at large values of the Bjorken variable. Corrections stemming from the center-of-mass motion of the pairs are estimated. We find that the relative probability per nucleon for 2N and 3N SRC has a soft dependence with mass number A and that the proton-neutron 2N SRC outnumber the proton-proton (neutron-neutron) 2N SRC. A linear relationship between the magnitude of the EMC effect and the predicted number of proton-neutron SRC pairs is observed. This provides support for the role of local nuclear dynamics on the EMC effect.

Rigorous formulation of two-parameter double-hybrid density-functionals

description: A two-parameter extension of the density-scaled double hybrid approach of Sharkas et al. [J. Chem. Phys. 134, 064113 (2011)] is presented. It is based on the explicit treatment of a fraction of multideterminantal exact exchange. The connection with conventional double hybrids is made when neglecting density scaling in the correlation functional as well as second-order corrections to the density. In this context, the fraction ac of second-order Møller-Plesset (MP2) correlation energy is not necessarily equal to the square of the fraction ax of Hartree-Fock exchange. More specifically, it is shown that ac \leq ax2, a condition that conventional semi-empirical double hybrids actually fulfill. In addition, a new procedure for calculating the orbitals, which has a better justification than the one routinely used, is proposed. Referred to as λ1 variant, the corresponding double hybrid approximation has been tested on a small set consisting of H2, N2, Be2, Mg2, and Ar2. Three conventional double hybrids (B2-PLYP, B2GP-PLYP, and PBE0-DH) have been considered. Potential curves obtained with λ1- and regular double hybrids can, in some cases, differ significantly. In particular, for the weakly bound dimers, the λ1 variants bind systematically more than the regular ones, which is an improvement in many but not all cases. Including density scaling in the correlation functionals may of course change the results significantly. Moreover, optimized effective potentials based on a partially-interacting system could also be used to generate proper orbitals. Work is currently in progress in those directions.

X-ray computed tomography scanning of ANU V244 was performed at CT Lab, Australian National University. Both CT data were segmented using Drishti Paint v2.7. Surface meshes were exported from Drishti Paint v2.7 and simplified using Drishti Render v2.7. Surface meshes were also imaged in Meshlab 2016 for detailed comparison.

Article abstract: Computational tomography is more and more widely used in many fields for its non-destructive and high-resolution means of detecting internal structures of the samples. 3D segmentation of computed tomography data, which sheds light on internal features of target objects, is increasingly gaining in importance. There are mature tools and software available to perform good 3D segmentation results. However, the powerful functionalities and capabilities of open-sourced software have not revealed fully. Here, using a set of scan data of fossil fish as a case study, we present a new release of open-source volume exploration, rendering, and 3D segmentation software, Drishti v2.7.
Furthermore, we also introduce a new tool for thresholding volume data (i.e. gradient thresholding) and a protocol for performing 3D segmentation includes using 3D Freeform Painter, mesh generation and simplification. We provide new tools and workflow to segment computed tomography data and thus benefiting the scientific community with more accurate and precise digital reconstruction, 3D modelling and 3D printing results. Our procedure is widely applicable not only in palaeontology, but also in biological, medical, and industrial researches. It can be used as a framework to segment computed tomography and other forms of volumetric data from any research field.
Violence denied, bodies erased : towards an interlocking spatial framework for queer anti-violence organizing
Creators: name: Holmes, Cindy
Publisher: name: University of British Columbia
Year: 2012

description: The research undertaken for this dissertation applies an interlocking spatial framework to the study of anti-violence strategies in queer communities in Canada, with a focus on British Columbia specifically. Drawing on anti-colonial feminist and queer activism and scholarship, it examines the implications of different ways of framing violence and space and their material effects. It encourages scholars and activists to expand the way we conceptualize and respond to violence, by examining the interlocking nature of different forms of violence and the spaces in which the violence occurs. This research asks: What are the stories that queer anti-violence organizers tell about the violence in our lives? What do these stories do? What, and whom do they make im/possible or in/visible, and how do they do this? What stories are told about place and space and what kinds of understandings of violence are made possible or erased through these imagined geographies? What strategies exist for resisting normative narratives and frameworks? To examine these questions, I focus on a discursive analysis of texts as well as on key social and historical moments through which I also engage in autoethnographic approaches. I critically analyze discourses in various texts including interview and focus group transcripts, lesbian anti-violence curricula, pamphlets and booklets, print and web-based news articles, a website for an urban development proposal, and a report from a human rights tribunal. To do this, I use an interdisciplinary framework, drawing on methodological tools from Women’s Studies, Geography, Social Work and Sociology. The research critiques the colonial, racialized, heteronormative and homonormative discursive practices and politics in queer and feminist anti-violence movements, and examines how different geographies and forms of violence, such as intimate partner violence and hate-motivated violence, are linked to the violence of imperialism, colonialism and nation-building. It also challenges normative and neoliberal constructions of subjectivity, health, safety, violence, belonging and citizenship in community-based feminist and queer anti-violence initiatives. My analysis reveals the way whiteness is produced through homonormative discourses, and offers anti-colonial and anti-normative strategies for change within feminist and queer anti-violence movements.

description: A series of polycrystalline SmFeAs1-xOx bulks was prepared to systematically investigate the influence of sample density on flux pinning properties. Different sample densities were achieved by controlling the pelletizing pressure. The superconducting volume fraction, the critical current densities Jcm and the flux pinning force densities Fp were estimated from the magnetization measurements. Experimental results manifest that: (1) the superconducting volume fraction decreases with the decreasing of sample density. (2) The Jcm values have the similar trend except for the sample with very high density may due to different connectivity and pinning mechanism. Moreover, The Jcm(B) curve develops a peak effect at approximately the same field at which the high-density sample shows a kink. (3) The Fp(B) curve of the high-density sample shows a low-field peak and a high-field peak at several temperatures, which can be explained by improved intergranular current, while only one peak can be observed in Fp(B) of the low-density samples. Based on the scaling behaviour of flux pinning force densities, the main intragranular pinning is normal point pinning.

title: The significance of culture in language learning: working with adult EFL learners in Mexico
Creators: name: Brookes-Lewis, Kimberly Anne
Publisher: name: University of Kent
Year: 2021

description: This is an inquiry into adult Mexican English foreign language learners' perceptions of the significance of culture in teaching and learning of English as a foreign language. The participants were Spanish-speaking adults studying at the university level in Morelia, Michoacan, Mexico. Working within the framework of qualitative-interpretative methodology, the focus of this inquiry is the investigation of the participants' perceptions of their experiences in the context of the inquiry in the classrooms. This context was an EFL course designed specifically for Spanish-speaking adults in Mexico based on the analysis of my personal experiences as an adult language learner and as an EFL teacher in Mexico. The research questions of this inquiry are: • What are adult learners' perceptions of beginning with an overview of the history and development of the target language? • What are adult learners' perceptions of learning about a particular target culture where the target language is spoken? • What are adult learners' perceptions of the inclusion of their maternal language and culture in foreign language learning? • What are adult learners' perceptions of working with awareness of language, culture and learning in the foreign language classroom? • What are adult learners' perceptions of explicit teaching in the foreign language classroom? The indications of this inquiry are that some adult EFL learners in Mexico perceive that an introduction to the target language and culture for the adult learner is called for in order to meet adult learner needs, along with the inclusion of the learner's maternal language and culture in EFL teaching and learning, an orientation to foreign language learning, and explicit teaching rather than other types of activities in the classroom. The practical application of these issues in the foreign language classroom with adults may not be indicated in all situations or appreciable for a" adult learners.

description: As a profession, veterinary medicine has ethical and legal obligations towards humankind, not just other species. Even so, investigations into medico-legal borderlands have yet to focus on veterinary expertise. This presentation centers on pop-up free clinics in a partnership between a social-service charity and a veterinary school. Social research has informed this service-learning initiative, from the outset. Most recently, our interdisciplinary team interviewed clients, social-service providers employed by the partnered charity, and qualified veterinarians who have participated as educators. The interview guides provided the foundation for an analytic matrix and team discussions. After that, with periodic input from team members and an emphasis on reflexivity, I led a thematic analysis vis-à-vis relevant scholarship, including previous publications arising from this service-learning initiative. Social-service providers indicated appreciation for the veterinary educators’ commitment to partnership. As for clients, they consistently reported feeling respected and valued at the pop-up free clinic, and they spoke of their pets as family members. Some clients registered concern about the veterinary-service barriers faced by poor people. The veterinarians, meanwhile, expressed profound angst and sorrow, consistent with a concept called “moral distress.” Social researchers, along with social-service providers and policy professionals, should pay more attention to moral distress amongst veterinary-service providers as a social problem. Only then might multi-species publics might become powerful enough to redress the root causes of the ethical quandaries and questioning that can arise from caring for marginalized multi-species families.

As an illustrative example, we consider a resonant tau-leptogenesis model, compatible with universal right-handed neutrino masses at the GUT scale, where the required heavy-neutrino mass splittings are generated radiatively. In particular, we explicitly demonstrate, how a minimum number of three heavy Majorana neutrinos is needed, in order to obtain successful leptogenesis and experimentally testable rates for processes of lepton flavour violation, such as mu --> e gamma and mu --> e conversion in nuclei.

description: We revisit the electroweak precision tests for Higgsless models of strong EWSB. We use the Vector Meson Dominance approach and express S and T via couplings characterizing vector and axial spin-1 resonances of the strong sector. These couplings are constrained by the elastic unitarity and by requiring a good UV behavior of various formfactors. We pay particular attention to the one-loop contribution of resonances to T (beyond the chiral log), and to how it can improve the fit. We also make contact with the recent studies of Conformal Technicolor. We explain why the second Weinberg sum rule never converges in these models, and formulate a condition necessary for preserving the custodial symmetry in the IR.

description: Detection of electrophoretic motion of ionic species using multi-dimensional Electrophoretic NMR (nD-ENMR) has demonstrated the potential to distinguish signals from two molecules in a solution mixture without their physical separation. Therefore, this technique may be applied for simultaneous structure determination of proteins and protein conformations, even during their biochemical interactions. Indeed, this has been achieved by introducing an additional dimension of electrophoretic mobility to the conventional multi-dimensional NMR by applying an external DC electric field. Consequently, the protein spectra are differently modulated by their electrophoretic mobilities in the electrophoretic flow dimension. Unfortunately, spectral resolution in the flow dimension has been limited by severe signal truncations due to the limited DC electric field available before onset of heating-induced convection. Linear prediction, which have been widely used for high-resolution spectral estimation from finite Fourier samples, have already been proposed to extend the truncated ENMR flow oscillation curves. However, we found that the spectral quality of linear prediction deteriorates as the spectral S/N decreases. To alleviate this problem, we have denoised the ENMR data using low pass filters prior to linear prediction. This technique has lead to improved resolution in the electrophoretic flow dimension. The approach was applied to analyze a 2D ENMR data matrix obtained from a mixture solution of two proteins ubiquitin and bovine serum albumin (BSA) in D2O.

description: The work presented in this thesis is concerned with modified polyionic cyclodextrins and their structural functionality with regards to forming host-guest inclusion complexes. Cyclodextrins are well-known to encapsulate a variety of hydrophobic molecules: however, only a few studies have been conducted to understand the impact of extending the cavity of well-defined cyclodextrins using alkyl side-chains with like charges on their termini. In Chapter 1:, the history and background information about cyclodextrin inclusion complexes was provided, along with a discussion of the precedence in literature and the theory surrounding the study of these supramolecular systems. Subsequently, Chapter 2: presented an outline of the synthetic schemes, and the work that was done, along with characterizations towards the polyionic cyclodextrin hosts that were then used for the analysis. Finally, in Chapter 3:, inclusion complexes between the synthesized polyionic hosts and a selection of steroid guest molecules were studied. NMR studies and ITC were used to gain a better understanding that the role the extension of the cavity played, as well as the impact of charges on the host molecule on the interaction with neutral and charged guest molecules. The guest molecules of choice were primarily steroid molecules, which are known to form complexes with cyclodextrin. Through these studies, binding constants, along with the thermodynamic parameters were obtained.

description: This project is part of the Northeast Structural Genomics Consortium (NESG). The goal of this consortium is to develop efficient and integrated technologies for high-throughput (HTP) protein production and 3D structure determination. This project focuses on the design of an image analysis system to classify protein crystal structures in a production oriented environment. The method presented performs classification of microscopic images as protein precipitates or crystals versus clear solutions. Preliminary experiments are presented, which provided high classification accuracy on large datasets of protein crystallization experiments using expert classification for ground truth.

description: In the realm of computer aided diagnosis (CAD) interactive segmentation schemes have been well received by physicians, where the combination of human and machine intelligence can provide improved segmentation efficacy with minimal expert intervention [1-3]. Transductive learning (TL) or semi-supervised learning (SSL) is a suitable framework for learning-based interactive segmentation given the scarce label problem. In this paper we present extended work on Bayesian transduction and regularized conditional mixtures for interactive segmentation [3]. We present a Markov random field model integrating a semi-parametric conditional mixture model within a Bayesian transductive learning and inference setting. The model allows efficient learning and inference in a semi-supervised setting given only minimal approximate label information. Preliminary experimental results on multimodal images of retinal disorders such as drusen, geographic atrophy (GA), and choroidal neovascularisation (CNV) with exudates and subretinal fibrosis show promising segmentation performance.
title: Sister chromatid exchanges occur in G₂-irradiated cells

description: DNA double-strand breaks (DSBs) are arguably the most important lesions induced by ionizing radiation (IR) since unrepaired or mis-repaired DSBs can lead to chromosomal aberrations and cell death. The two major pathways to repair IR-induced DSBs are non-homologous end-joining (NHEJ) and homologous recombination (HR). Perhaps surprisingly, NHEJ represents the predominant pathway in the G1 and G2 phases of the cell cycle, but HR also contributes and repairs a subset of IR-induced DSBs in G2. Following S-phase-dependent genotoxins, HR events give rise to sister chromatid exchanges (SCEs), which can be detected cytogenetically in mitosis. Here, we describe that HR occurring in G2-irradiated cells also generates SCEs in ~50% of HR events. Since HR of IR-induced DSBs in G2 is a slow process, SCE formation in G2-irradiated cells requires several hours. During this time, irradiated S-phase cells can also reach mitosis, which has contributed to the widely held belief that SCEs form only during S phase. We describe procedures to measure SCEs exclusively in G2-irradiated cells and provide evidence that following IR cells do not need to progress through S phase in order to form SCEs.
On a tendency in health economics to dwell on income inequality and underestimate social stress

description: Social stress can cause physical and mental harm. It is therefore not surprising that public health policy makers have sought to identify and implement policies aimed at tackling this social ill. A frequently prescribed remedy is to reduce social stress by reducing income inequality, which is typically measured by the Gini coefficient. Decomposing the coefficient into a measure of a population’s social stress and a population’s income makes it possible to show that steps taken to lower the coefficient can actually exacerbate social stress. We formulate conditions under which lowering the Gini coefficient coincides with increasing social stress. If the aim of public policy is to improve public health and increase social welfare, and if social welfare is reduced by social stress, then lowering the Gini coefficient may not be the right course of action.

description: By exploiting a "mixed" non-symmetric Freudenthal-Rozenfeld-Tits magic square, two types of coset decompositions are analyzed for the non-compact special Kähler symmetric rank-3 coset E7(-25)/[(E6(-78) x U(1))/Z_3], occurring in supergravity as the vector multiplets' scalar manifold in N=2, D=4 exceptional Maxwell-Einstein theory. The first decomposition exhibits maximal manifest covariance, whereas the second (triality-symmetric) one is of Iwasawa type, with maximal SO(8) covariance. Generalizations to conformal non-compact, real forms of non-degenerate, simple groups "of type E7" are presented for both classes of coset parametrizations, and relations to rank-3 simple Euclidean Jordan algebras and normed trialities over division algebras are also discussed.

Re-Storying the Past: Transforming the White Settler Colonial Stories that Formed Us

description: In this study, I explore the ways Settler nurse educators understand their identity within the context of Canada’s colonial narrative. I provide a generative space for critical reflectivity on my own social location through creative, embodied explorations of my Settler-colonial story and experiences, Indigenous historical accounts, and dialogical engagement with Canada’s socio-historical configuration as a Settler nation-state. I consider the ways Whiteness , (DiAngelo, 2018a), Settler identity (Tuck & Yang, 2012; Wolfe, 2006), and Settler colonial logics act as barriers to transforming Settler understanding of Canada’s Settler colonial history and Indigenous sovereignty (Donald, 2009). Using Indigenous Métissage as a research sensibility, I engage in narrative and embodied practices to better understand and transform my relationship to self, land, and Canada’s colonial history. Through braided stories of place, practices, and historical perspectives, I examine the impact that Camp Chief Hector had on my White settler formation and its exclusionary and exploitative relationship with the Stoney Nakoda Nation. I consider a path towards reconciliation; one created by attending to respect and reverence, reciprocity, kinship relationality, and treaty responsibility. By thinking through my lived experiences as an entry point to engage Settler identity, I tell a more truthful account of Canadian history and of the current state of how Settler colonial logics influence the relationship between Settlers and Indigenous people.

description: The open standard for particle-mesh data (openPMD) is a community meta-data standard. openPMD adds scientific self-description in a machine-actionable format to data sets, which allows sharing data processing frameworks, chaining data through simulations and designing long analysis pipelines. Developed in the open as a FAIR data standard, openPMD is based on portable and scalable file formats such as HDF5 and ADIOS2, among others. As of today, openPMD has been adopted in many popular modeling and analysis projects in laser-plasma physics, particle accelerator physics and beyond. In this talk, we will present the community principles, existing implementations, recent research results for file and file-less analysis, and possible integration directions.
