title: Form Follows Sound: Designing For Sound Awareness

Year: 2018
Subjects: subject: Visual communication

subject: City sounds
subject: Sound-waves

description: Sound is a prominent feature of our urban environment, affecting us in many ways. Studies show that sound levels in cities are increasing every year. Considering the fact that our well-being is closely related to everyday sound, there is an apparent interconnection between them. Active listening to the surrounding acoustic environment offers the ability to appreciate sounds and articulate auditory needs having an impact on our well-being. Being aware of sound and expressing what we want to hear can lead to tangible transformation and change in our urban acoustic environment and space. This thesis explores the potential of sound visualization and the representation of auditory information as a means of enhancing perception about urban sounds in our daily interactions. Through practice-based design research, studies in sound and music visualization with a focus on perception of shapes and semiotics, the main body of this work intends to gain insights into sound perception and its potential relationship with visual form. This research led to the creation of ‘Right Hear’, a map depicting the evolving soundscapes of Vancouver. ‘Right Hear’ aims to invite users to explore their own acoustic sense of place and become aware of the urban sounds by offering the ability to simultaneously listen and see sounds on a visual map. In parallel with this, the body of this work led to a series of exercises in the notation of sound and translation of graphic scores that looks into the ways that people from diverse fields of practice perceive, translate and respond to abstract shapes.

description: Long-distance fiber-based quantum communication relies on efficient non-classical light sources operating at telecommunication wavelengths. Semiconductor quantum dots are promising candidates for on-demand generation of single photons and entangled photon pairs for such applications. However, their brightness is strongly limited due to total internal reflection at the semiconductor/vacuum interface. Here we overcome this limitation using a dielectric antenna structure. The non-classical light source consists of a gallium phosphide solid immersion lens in combination with a quantum dot nanomembrane emitting single photons in the telecom O-band. With this device, the photon extraction is strongly increased in a broad spectral range. A brightness of 17% (numerical aperture of 0.6) is obtained experimentally, with a single photon purity of 𝑔(2)(0)=0.049±0.02 at saturation power. This brings the practical implementation of quantum communication networks one step closer.

Democratic Republic of the Congo

description: Due to prolonged conflict, millions of people in the Democratic Republic of the Congo (DRC) have fled their homes to seek refuge elsewhere, especially in the east of the country. The majority of these Internally Displaced Persons (IDPs) flee to cities and other local communities rather than to displacement camps. Bukavu, the capital of the South-Kivu province, is a case in point. In recent years, Bukavu grew rapidly due to the influx of IDPs and other migrants – mostly from the nearby districts. Yet, in the city, IDPs largely fend for themselves, and many experience socio-economic precarity. Connectivity is one of the ways in which IDPs can improve their situation. The first and most important connection that IDPs mobilise upon arrival are familial ties. It is from here that they start a ‘chain of connectivity’ on the road towards local integra- tion. Our research in Bukavu shows that many people depend on others in being or becoming self-reliant: They get access to employment, housing or basic services through their networks.

description: Many long-range modifications of the Newtonian/Einsteinian standard laws of gravity have been proposed in the recent past to explain various celestial phenomena occurring at different scales ranging from solar system to the entire universe. The most famous ones are the so-called Pioneer anomaly, {i.e.} a still unexplained acceleration detected in the telemetry of the Pioneer 10/11 spacecraft after they passed the 20 AU threshold in the solar system, the non-Keplerian profiles of the velocity rotation curves of several galaxies and the cosmic acceleration. We use the latest observational determinations of the planetary motions in the solar system and in the double pulsar system to put constraints on such models independently of the phenomena for which they were originally proposed. We also deal with the recently detected anomalous perihelion precession of Saturn and discuss the possibility that it can be explained by some of the aforementioned models of modified gravity.

The cranking formula and the spurious behaviour of the mass parameters

description: We discuss some aspects of the approach of the mass parameters by means of the simple cranking model. In particular, it is well known that the numerical application of this formula is often subject to ambiguities or contradictions. It is found that these problems are induced by the presence of two derivatives in the formula. To overcome these problems, we state a useful ansatz and we develop a number of simple arguments which tend to justify the removal of these terms. As soon as this is done, the formula becomes simpler and easier to interpret. In this respect, it is shown how the shell effects affect the mass parameters. A number of numerical tests help us in our conclusions.

CARE Principles of Indigenous Data Governance

description: Presentation to Research Data Alliance, April 2021, at this session "Stewardship of Indigenous Peoples’ Data: Use Cases for Repositories and Collections", https://www.rd-alliance.org/plenaries/rda-17th-plenary-meeting-edinburgh-virtual/stewardship-indigenous-peoples%E2%80%99-data-use-cases. Talk Abstract: The Earth Science Information Partners (ESIP) regularly collaborates with community members to provide direction for implementing data-related policies. Here, we present the process used by an ESIP cluster to align data repository practices with the CARE principles, and to produce guidelines for repositories to meet the CARE Principles in conjunction with other frameworks such as the FAIR and TRUST Principles. The tenets of the CARE Principles are each being considered in terms of the feasibility of their implementation within a data repository system. Such considerations include balancing existing repository activities with the needs of scientists, data producers, data users, and other stake and rights holders.
Type IIA orientifold compactification on SU(2)-structure manifolds

Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We investigate the effective theory of type IIA string theory on six-dimensional orientifold backgrounds with SU(2)-structure. We focus on the case of orientifolds with O6-planes, for which we compute the bosonic effective action in the supergravity approximation. For a generic SU(2)-structure background, we find that the low-energy effective theory is a gauged N=2 supergravity where moduli in both vector and hypermultiplets are charged. Since all these supergravities descend from a corresponding N=4 background, their scalar target space is always a quotient of a SU(1,1)/U(1) x SO(6,n)/SO(6)xSO(n) coset, and is therefore also very constrained.

The biosynthesis of two naturally-occurring auxins in Pisum sativum L.
Creators: name: Tivendale, ND
Publisher: name: University Of Tasmania
Year: 2023

description: Auxins are a group of phytohormones, including indole-3-acetic acid (IAA) and 4-chloroindole-3-acetic acid (4-Cl-IAA), that are involved in many aspects of plant growth, including phototropism, gravitropism, shoot elongation, root initiation and flowering. The structure of the primary auxin‚ÄövÑvÆIAA‚ÄövÑvÆwas determined over 70 years ago, but the biosynthesis of this molecule, and the other naturally-occurring auxins, has remained unclear. Five pathways have been proposed for IAA biosynthesis, one tryptophan (Trp)-independent pathway and four Trp-dependent pathways. Each of the Trp-dependent pathways is named after its primary intermediate, giving rise to the indole-3-acetaldoxime, tryptamine, indole-3-acetamide and indole-3-pyruvic acid pathways. At the outset of this research, the evidence for each of these pathways was incomplete, even in the model organism Arabidopsis thaliana. This thesis reports the determination of the primary auxin biosynthesis route in the seeds of Pisum sativum (pea). The indole-3-acetaldoxime pathway was not investigated, as it has been shown previously that pea lacks the necessary enzymes for this pathway and is devoid of endogenous indole-3-acetaldoxime. First, the tryptamine pathway was examined. The mass spectral characterisation of authentic N-hydroxytryptamine (synthesised in our laboratory), a reported intermediate in the tryptamine pathway and the alleged in vitro product of the YUCCA enzymes, cast serious doubts over the role of this compound in auxin biosynthesis. It was also shown, through injection of labelled `[D_4]Trp` and \\([D_5]tryptamine\\), that tryptamine is not converted to IAA in pea seeds, indicating that this pathway does not function in these organs. This left three possible pathways to auxin. Through in vivo feeding experiments, the Trp-independent and the indole-3-acetamide pathways were eliminated as possibilities in pea seeds. The remaining pathway, the indole-3-pyruvic acid pathway, was investigated using a number of lines of enquiry. First, the functional activity of two Trp aminotransferase genes from pea (PsTAR1 and PsTAR2) was investigated using purified recombinant PsTAR1 and PsTAR2. This showed that these proteins convert Trp to indole-3-pyruvic acid and 4-chlorotryptophan to 4-chloroindole-3-pyruvic acid. A standard of the latter compound was synthesised in our laboratory, for comparison with the enzyme product. Secondly, feeding studies using \\([^{13}C_6]IAA\\) and \\([D_5]Trp\\) indicated that Trp is converted to 4-Cl-Trp, which is then converted to 4-Cl-IAA. Taken together, the evidence presented in this thesis supports parallel biosynthesis of IAA and 4-Cl-IAA by the IPyA pathway and its chlorinated version.

description: Two independent surveys within the last 20 years found that most of the food consumed in Papua New Guinea (PNG) is produced within PNG. The 1996 PNG Household Survey (Gibson 2001), a consumption survey, found that 84 per cent of calories consumed in rural areas and 50 per cent of calories consumed in urban areas, were produced in PNG. Bourke (2009a) used the Mapping Agriculture Systems in PNG (MASP) data to estimate that 83 per cent of food energy and 76 per cent of protein consumed in PNG was produced in PNG. The very great majority of this food is produced by rural people from their customary land, using their own labour, with almost no external inputs.
Constraints on Dark Matter Annihilation in Clusters of Galaxies with the Fermi Large Area Telescope

description: Nearby clusters and groups of galaxies are potentially bright sources of high-energy gamma-ray emission resulting from the pair-annihilation of dark matter particles. However, no significant gamma-ray emission has been detected so far from clusters in the first 11 months of observations with the Fermi Large Area Telescope. We interpret this non-detection in terms of constraints on dark matter particle properties. In particular for leptonic annihilation final states and particle masses greater than ~200 GeV, gamma-ray emission from inverse Compton scattering of CMB photons is expected to dominate the dark matter annihilation signal from clusters, and our gamma-ray limits exclude large regions of the parameter space that would give a good fit to the recent anomalous Pamela and Fermi-LAT electron-positron measurements. We also present constraints on the annihilation of more standard dark matter candidates, such as the lightest neutralino of supersymmetric models. The constraints are particularly strong when including the fact that clusters are known to contain substructure at least on galaxy scales, increasing the expected gamma-ray flux by a factor of ~5 over a smooth-halo assumption. We also explore the effect of uncertainties in cluster dark matter density profiles, finding a systematic uncertainty in the constraints of roughly a factor of two, but similar overall conclusions. In this work, we focus on deriving limits on dark matter models; a more general consideration of the Fermi-LAT data on clusters and clusters as gamma-ray sources is forthcoming.

We present analytical results in the SM and in the SMEFT and discuss several practical aspects, like the choice of quantization axes and $t \bar t$ threshold effects. We also note a correspondence between parity symmetry and entanglement. We find that quantum observables exhibit a rich phenomenology in the SM, and can also provide additional leverage in detecting new physics residing at higher scales.

description: A combination of helium- and gallium-ion beam milling together with a fast and reliable sketch-and-peel technique is used to fabricate gold nanorod dimer antennas with an excellent quality factor and with gap distances of less than 6 nm. The high fabrication quality of the sketch-and-peel technique compared to a conventional ion beam milling technique is proven by polarisation-resolved linear dark-field spectromicroscopy of isolated dimer antennas. We demonstrate a strong coupling of the two antenna arms for both fabrication techniques, with a quality factor of more than 14, close to the theoretical limit, for the sketch-and-peel-produced antennas compared to only 6 for the conventional fabrication process. The obtained results on the strong coupling of the plasmonic dimer antennas are supported by finite-difference time-domain simulations of the light-dimer antenna interaction. The presented fabrication technique enables the rapid fabrication of large-scale plasmonic or dielectric nanostructures arrays and metasurfaces with single-digit nanometer scale milling accuracy. © 2020 Christoph Lienau, Martin Silies et al., published by De Gruyter, Berlin/Boston.
The geography of migration in Tasmania, 1921-1961
Creators: name: Farmer, RSJ
Publisher: name: University Of Tasmania
Year: 2023

description: Originally it was planned to intensively study the spatial aspects of selected migration topics by means of a sample survey in areas chosen in the light of an analysis of census data. This idea has been transformed into a general study of the geography of migration in Tasmania between 1921 and 1961. It soon became clear in the preliminary investigation of the demographic and migratory 'background' that a general survey was necessary to identify the problems that require intensive study and to provide a general frame of reference. Perhaps a word is called for about the large number of tables included in the second volume of the thesis: they arise from the writer's belief that the analysis of quantitative data is seriously impaired if the basic material is not available for examination. Not only do the 181 tables discussed in the text and the three appendix tables contain considerable information that has had to be neglected in order to keep the study within reasonable limits but also the tables that have not been included in the thesis. These tables are available and readers interested in greater detail should contact the writer- care of the Department of Geography in the University of Tasmania.
Lateral stability of glulam arches
Creators: name: Charlwood, Robin Gurney
Publisher: name: University of British Columbia
Year: 2011

description: The lateral buckling of two hinged glulam parabolic arches of rectangular cross-section with laterally restrained top edges is investigated. The problem is formulated using the stiffness method. The structure is idealised as a series of straight segments. A stiffness matrix including the effects of lateral bending and torsion is derived and it is shown how the structure stiffness matrix is generated. The buckling load is defined as the smallest load at which the structure stiffness matrix becomes singular. Three methods of solution are given; iteration, determinant plot and Southwell plot. Experimental tests were carried out to check the validity of the theory. The results of the tests are presented and are shown to be satisfactory. A set of numerical results are given for a range of arches and load distributions and a set of design parameters are proposed.

description: We use the power-counting formalism of effective field theory to study the size of loop corrections in theories of slow-roll inflation, with the aim of more precisely identifying the limits of validity of the usual classical inflationary treatments. We keep our analysis as general as possible in order to systematically identify the most important corrections to the classical inflaton dynamics. Although most slow-roll models lie within the semiclassical domain, we find the consistency of the Higgs-Inflaton scenario to be more delicate due to the proximity between the Hubble scale during inflation and the upper bound allowed by unitarity on the new-physics scale associated with the breakdown of the semiclassical approximation within the effective theory. Similar remarks apply to curvature-squared inflationary models.

description: A class of pseudo-hermitian quantum system with an explicit form of the positive-definite metric in the Hilbert space is presented. The general method involves a realization of the basic canonical commutation relations defining the quantum system in terms of operators those are hermitian with respect to a pre-determined positive definite metric in the Hilbert space. Appropriate combinations of these operators result in a large number of pseudo-hermitian quantum systems admitting entirely real spectra and unitary time evolution. The examples considered include simple harmonic oscillators with complex angular frequencies, Stark(Zeeman) effect with complex electric(magnetic) field, non-hermitian general quadratic form of N boson(fermion) operators, symmetric and asymmetric XXZ spin-chain in complex magnetic field, non-hermitian Haldane-Shastry spin-chain and Lipkin-Meshkov-Glick model.

description: We consider the Regge limit of a CFT correlation function of two vector and two scalar operators, as appropriate to study small-x deep inelastic scattering in N=4 SYM or in QCD assuming approximate conformal symmetry. After clarifying the nature of the Regge limit for a CFT correlator, we use its conformal partial wave expansion to obtain an impact parameter representation encoding the exchange of a spin j Reggeon for any value of the coupling constant. The CFT impact parameter space is the three-dimensional hyperbolic space H3, which is the impact parameter space for high energy scattering in the dual AdS space. We determine the small-x structure functions associated to the exchange of a Reggeon. We discuss unitarization from the point of view of scattering in AdS and comment on the validity of the eikonal approximation. We then focus on the weak coupling limit of the theory where the amplitude is dominated by the exchange of the BFKL pomeron. Conformal invariance fixes the form of the vector impact factor and its decomposition in transverse spin 0 and spin 2 components. Our formalism reproduces exactly the general results predict by the Regge theory, both for a scalar target and for gamma*-gamma* scattering. We compute current impact factors for the specific examples of N=4 SYM and QCD, obtaining very simple results. In the case of the R-current of N=4 SYM, we show that the transverse spin 2 component vanishes. We conjecture that the impact factors of all chiral primary operators of N=4 SYM only have components with 0 transverse spin.

description: This thesis investigates how design activities taken on by makers and designers can illuminate real-world, contemporary issues relevant to the new BC Curriculum. The recent redesign of British Columbia’s K-12 Applied Design Skills and Technologies (ADST) curriculum aims to support the development of active citizens in a way that is in touch with today’s rapid pace of technology development and information exchange (Ministry of Education, 2015). As a designer and maker, who is also informed by observations and work with Vancouver’s maker community, Emily Smith has explored possible directions and philosophies for developing a maker education-pedagogy, informed by the maker movement, her own practices, and the Emily Carr students and faculty. This work is an exploration of TOOLS: Including drop spindles, knitting needles, and backstrap looms; METHODS: Including her own artistic textile and music-making practice and primary persona known as a “One-Woman Band”. This persona is an application of clowning practices, as taught by David Macmurray Smith. Methods borrowed from the maker community include designed materials and facilitation in the form of “Lightning Talks”, and “Zine-Making” (Appendix C). Finally, this thesis explores MINDSETS: which includes constructivism and constructionism, Design-Make-Play, Head, Heart and Hand, the Maker Mindset, the work of Maryann and Gregory Bateson and cybernetics. Guided by exploration of tools, methods and mindsets, Smith conducts a series of co-creation sessions and interviews with 15 participants (see Appendix A B), which include Emily Carr students, local makers, faculty and educators in Vancouver. Findings provide a series of case studies which reveal that social making activities engage learners in a multiplicity of subjects, and can meaningfully address ADST’s Core Competencies through making, and discussion led by a facilitator. Other insights include possibilities to inspire students through the use of “memes”, through public forums, programs, and published materials. Designed materials constitute prototypes and proof of concepts for possible extensions and modules to further extend and develop the Maker Club format.

description: There is a pressing need to shift present expectations of urban lifestyle in contemporary western society — to reconsider how we can sustain ourselves and our planet. Shifting understanding of our relationship to our built environment may play a role in adjusting expectations of the future. In doing so, we can start to look towards alternate ideas and new possibilities for the material culture found within the home. This thesis seeks to expose how we see and organize our homes through aesthetics, language and meaning. It considers how this affects our perception of our built and natural environments — our separation of space — in a social sense. A generative process-led design practice is used to find means, through artifact, to have others (first the designer, and in turn, users/consumers) think critically about current understandings of urban lifestyle, and aspirations connected to desired standards of living. A series of small projects that explore themes of care, control and expectations are used as a catalyst for discussion. The intent is not to find solutions for sustainable design but rather to communicate and promote consideration about sustainability, the home environment, and material culture.
Thermally activated intermittent flow in amorphous solids

Year: 2024
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Using mean field theory and a mesoscale elastoplastic model, we analyze the steady state shear rheology of thermally activated amorphous solids. At sufficiently high temperature and driving rates, flow is continuous and described by well-established rheological flow laws such as Herschel-Bulkley and logarithmic rate dependence. However, we find that these flow laws change in the regime of intermittent flow, were collective events no longer overlap and serrated flow becomes pronounced. In this regime, we identify a thermal activation stress scale, $x_{a}(T,\dotγ)$, that wholly captures the effect of driving rate $\dotγ$ and temperature $T$ on average flow stress, stress drop (avalanche) size and correlation lengths. Different rheological regimes are summarized in a dynamic phase diagram for the amorphous yielding transition. Theoretical predictions call for a need to re-examine the rheology of very slowly sheared amorphous matter much below the glass transition.

description: Eutectic samples of Sr2RuO4-Ru possess many micrometer-sized Ru-metal inclusions. Based on a Ginzburg-Landau formulation we analyze the interplay of the chiral p-wave state of Sr2RuO4 (Tc = 1.5 K) and the s-wave state of Ru metal (Tc,Ru = 0.5 K) for an inclusion of cylindrical geometry. As a consequence of the mismatch of the order parameter phase, the occurrence of a spontaneous flux distribution appears for T < Tc,Ru which evolves into a "Josephson vortex" on the Sr2RuO4-Ru interface. At a sufficiently low temperature a depinning transition can occur whereby the vortex moves to the center of the cylinder.

The British army and the counter-insurgency campaign in Van Diemen's Land with particular reference to the black line
Creators: name: McMahon, JF

Year: 2023

description: The British Army of the 1820's was not trained far counter-insurgency duties to operate in small detached parties. Their role in the campaign against the Aborigines was to aid the civil power, and tensions and inefficiencies resulted when troops were drected and commanded by civilians. The colonial garrison was commanded by an experienced soldier and administrator, lieutenant-Governor George Arthur. He exercised a dual civil/military function ensuring all resources were integrated through an administrative system centred on his police districts. By 1830, Arthur sought a solution to the Aboriginal problem based on a dual strategy of conciliation in the tribal lands, and use of military force, to expel the natives from the settled areas. The Aborigines developed formidable skills as guerilla fighters, and their tactics took advantage of their enemies' weapons limitations. With loss of tradtional hunting grounds, the Aborigines were forced to rely on raiding settlers' huts for supplies. This generated stronger countermeasures, such as martial law in 1828 and the Black Line in 1830, which was the climax of the counter-insurgency campaign. This was a sweep and cordon operation, combining troops, and civilians who were called out under a levy en masse, under Army command. The troops, now under command of their own officers, were disciplined and efficient. Opinions differ in contemporary and historical writings, concerning the Black Line, as to whether it was a 'fiasco' or, in terms of Arthur's dual strategy, a success. As he dd not achieve his military aim to confine the Aborigines in Tasman's Peninsula, the line was a failure, but due to Walpole's contact, it was not a total failure, and as it was meticulously planned and executed, the term 'fiasco' is inappropriate. As the Line directly assisted the conciliatory arm of the dual strategy, it contributed to Arthur's long term goal. Almost a mythology has developed over aspects of the line. Arthur distorted fact in insisting that Walpole's contact, and the presence of convicts with the Aborigines, led to the failure of his military obiective. Without recognising the temper of the times, and that the Line was Arthtur's only remaining military option, the 'fiasco' school of 'Writers has unfairly branded the Black Line as a foolish enterprise. Historians' statements of numbers deployed on the line vary considerably, a minor, but pertinent example of how an error can develop by uncritical acceptance of one primary source.The counter-insurgency campaign in the police districts and on the Black Line, while being a minor footnote in the annals of the British Army, is a sigificant but often misunderstood or forgotten phase of Tasmanian history. It deserves more recognition by Tasmanian and Australian military historians.

description: Complex network approaches have recently been applied to continuous spatial dynamical systems, like climate, successfully uncovering the system's interaction structure. However the relationship between the underlying atmospheric or oceanic flow's dynamics and the estimated network measures have remained largely unclear. We bridge this crucial gap in a bottom-up approach and define a continuous analytical analogue of Pearson correlation networks for advection-diffusion dynamics on a background flow. Analysing complex networks of prototypical flows and from time series data of the equatorial Pacific, we find that our analytical model reproduces the most salient features of these networks and thus provides a general foundation of climate networks. The relationships we obtain between velocity field and network measures show that line-like structures of high betweenness mark transition zones in the flow rather than, as previously thought, the propagation of dynamical information.
An experimental study of plastic behavior of short lengths of wide flange steel columns
Creators: name: Jewsbury, Frank Edward
Publisher: name: University of British Columbia
Year: 2011

description: This is an experimental study of the plastic yielding of steel columns. It consists of tests of four specimens; two tension coupons, a 12-inch stub column and a 21-inch stub column. The tension tests were used to determine the physical properties of the material while the stub columns demonstrated the effects of residual stress upon the initiation of yielding and the propagation of the yielding. The test procedure used in both the tension tests and the compression tests was the same. The specimen was loaded in increments up to a load just, below the yield point. Beyond that point the specimen was strained at a constant rate in order to neutralize the effects of creep. This test procedure required that all the data for each set of readings be adjusted to give the strain at any gauge on the specimen at the same instant of time. This was done by considering the differences between consecutive sets of readings and adjusting all strains to the strain at the gauge showing the greatest change during the set. This was done by means of a computor [sic] program. During the tests of the stub columns local buckling of the flanges and web was restrained by a system of bars and bracing frames. The system used in the test of the 21-inch stub column proved to be particularly successful. Data was collected from strain gauges in the tension tests and strain and dial gauges in the compression test. The dial gauges in the compression test provided confirmation that the strain gauges accurately represented the state of strain in the specimens and also rotation of the upper end of the stub columns during the tests. There are several general conclusions which, it must be emphasized, are based upon a small number of tests. The yield stress of the tension specimens was greater than of the compression specimens. Yielding initiates at several independent foci rather than propagating from one single point. Yielding, once commenced, generally continued without stopping well into the strain hardened region. Therefore, there are both unyielded material and strain hardened material in the specimen at the same time. The initiation and progress of plastic deformations in the specimen are greatly affected by even small local irregularities. The effect of residual stresses upon the initiation of yielding is not uniform. The strain hardening modulus of the specimens used has been found to be only about one-half of that expected. Wide variation of this property is common.

description: Gravitational waves (GWs) induce correlated perturbations to the arrival times of pulses from an array of galactic millisecond pulsars. The expected correlations, obtained by averaging over many pairs of pulsars having the same angular separation (pulsar averaging) and over an ensemble of model universes (ensemble averaging), are described by the Hellings and Downs curve. As shown by Allen [Phys. Rev. D 107, 043018 (2023)], the pulsar-averaged correlation will not agree exactly with the expected Hellings and Downs prediction if the gravitational-wave sources interfere with one another, differing instead by a "cosmic variance" contribution. The precise shape and size of the cosmic variance depends on the statistical properties of the ensemble of universes used to model the background. Here, we extend the calculations of the cosmic variance for the standard Gaussian ensemble to an ensemble of model universes which collectively has rotationally invariant correlations in the GW power on different angular scales (described by an angular power spectrum, $C_\ell$ for $\ell=0,1,\cdots$.). We obtain an analytic form for the cosmic variance in terms of the $C_\ell$'s and show that for realistic values $C_{\ell}/C_0\lesssim 10^{-3}$, there is virtually no difference in the cosmic variance compared to that for the standard Gaussian ensemble (which has a zero angular power spectrum).

description: Background and Purpose— We sought to evaluate safety and efficacy of mechanical thrombectomy in patientswith anterior circulation large vessel occlusion strokes presented after 6 hours of last known well and selected basedon Diffusion Weighted Imaging (DWI)-Alberta Stroke Program Early Computed Tomography Score (ASPECTS) onMagnetic Resonance Image (MRI).Methods— Consecutive patients presented with large vessel occlusion strokes were enrolled from January 2019-Au-gust 2019 in two-stroke centers if they had anterior circulation ischemic stroke due to intracranial internal carotidartery (ICA) or proximal middle cerebral artery (MCA) occlusion and had a baseline DWI-ASPECTS >5. Patientsunderwent mechanical thrombectomy plus best medical management or best medical management alone dependingupon the hospital of presentation. The primary outcome was the shift in the degree of disability at 90-day as measuredby the modified Rankin scale (mRS). Secondary outcome was functional independence at 90-day (mRS 0-2). Safetymeasures were the rates of symptomatic intracranial hemorrhage (sICH) and 90-day mortality.

Results— Fifty-seven patients were eligible for the analysis. Demographics, and baseline clinical characteristicswere similar between the patients who underwent mechanical thrombectomy (n=32) and control groups (n=25).Mechanical thrombectomy was associated with a favorable shift in the overall distribution of 90-day mRS (P<0.001,adjusted odds ratio; 7.985, 95% cofidence interval (CI) [2.759-25.031], p<0.001). Similarly, patients who underwentmechanical thrombectomy had higher rates of functional independence (56.3% vs. 12%, p=0.001, adjusted oddsratio; 16.760, 95% CI [2.822-99.548], p=0.002) at 90 days. The rates of sICH and 90-day mortality were similarbetween the two groups.Conclusions— We found that patients presenting after 6 hours of last well-known normal benefit from mechanicalthrombectomy when selected based on Diffusion Weighted Imaging-ASPECTS.

Exekutive Funktion
überfachliche Kompetenz

description: Beim selbstständigen Arbeiten im Unterricht tauchen oft Probleme auf, die es nicht gäbe, wenn die Kinder über die entsprechenden überfachlichen Kompetenzen gemäss Lehrplan 21 verfügen würden. Doch wie diese wichtigen Kompetenzen im Unterricht gefördert werden können, wird im Lehrplan nicht beschrieben. Ausserdem fehlt im Lehrplan ein expliziter Bezug zu den exekutiven Funktionen, obwohl diese die Basis für das Handeln und Lernen darstellen. Anhand von zwei Experteninterviews und der Analyse von drei überfachlichen Kompetenzen, werden die zentralen Verbindungen zwischen den überfachlichen Kompetenzen und den exekutiven Funktionen hergestellt. Die gewonnenen Erkenntnisse fliessen in die Entwicklung eines Produktes ein, mit welchem die exekutiven Funktionen gestärkt und die überfachlichen Kompetenzen aufbauend gefördert werden können. Das erstellte Produkt wird in drei Klassen, während vier Wochen im integrativen Unterricht eingesetzt und auf seine Wirkung hin überprüft.
