description: In this paper, authors shall introduce a finite element method by using a weakly defined gradient operator over discontinuous functions with heterogeneous properties. The use of weak gradients and their approximations results in a new concept called {\em discrete weak gradients} which is expected to play important roles in numerical methods for partial differential equations. This article intends to provide a general framework for operating differential operators on functions with heterogeneous properties. As a demonstrative example, the discrete weak gradient operator is employed as a building block to approximate the solution of a model second order elliptic problem, in which the classical gradient operator is replaced by the discrete weak gradient. The resulting numerical approximation is called a weak Galerkin (WG) finite element solution. It can be seen that the weak Galerkin method allows the use of totally discontinuous functions in the finite element procedure. For the second order elliptic problem, an optimal order error estimate in both a discrete $H^1$ and $L^2$ norms are established for the corresponding weak Galerkin finite element solutions. A superconvergence is also observed for the weak Galerkin approximation.

A morphotropic phase boundary system based on polarization rotation and polarization extension
Creators: name: Damjanovic, Dragan

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Many ferroelectric solid solutions exhibit enhanced electro-mechanical properties at the morphotropic boundary separating two phases with different orientations of polarization. The mechanism of properties enhancement is associated with easy paths for polarization rotation in anisotropically flattened free energy profile. Another mechanism of properties enhancement related to free energy flattening is polarization extension. It is best known at temperature-driven ferroelectric-paraelectric phase transitions and may lead to exceedingly large properties. Its disadvantage is temperature instability of the enhancement. In this paper a temperature-composition phase diagram is proposed that exhibits compositionally driven-phase transitions with easy paths for both polarization rotation and polarization extension.

description: The formation of Polycyclic Aromatic Hydrocarbons in the circumstellar outflows of evolved stars is reviewed, with an emphasis on carbon stars on the Asymptotic Giant Branch. Evidence for PAHs present in their winds is provided by meteoritic studies and recent observations of the Unidentified Infrared bands. We detail the chemical processes leading to the closure of the first aromatic ring as well as the growth mechanisms leading to amorphous carbon grains. Existing studies on PAH formation in evolved stellar envelopes are reviewed and new results for the modelling of the inner wind of the archetype carbon star IRC+10216 are presented. Benzene, C6H6, forms close to the star, as well as water, H2O, as a result of non-equilibrium chemistry induced by the periodic passage of shocks. The growth process of aromatic rings may thus resemble that active in sooting flames due to the presence of radicals like hydroxyl, OH. Finally, we discuss possible formation processes for PAHs and aromatic compounds in the hydrogen-rich R CrB star, V854 Cen, and their implication for the carriers of the Red Emission and the Diffuse Interstellar Bands.

Quantifying spatial-temporal change in habitat occupancy patterns of grizzly bears (Ursus arctos) in the context of industrial activities in western Alberta
Creators: name: Irwin, Mackenzie Kate

description: Landscape change is a primary driver of global species decline, requiring effective approaches for monitoring wildlife populations. Occupancy modelling, which estimates the probability of a species being present on a landscape, has become a popular method for monitoring wildlife populations and habitat quality. Among large mammal species in North America, grizzly bears (Ursus arctos) are particularly vulnerable to and threatened by anthropogenic pressures. Using hair-snag data collected in 2004 and 2014 from a threatened grizzly bear population in Alberta, Canada, this research developed single-season occupancy models to understand how anthropogenic disturbance and landscape conditions influence occupancy patterns of male and female grizzly bears over a decade. I then quantified spatial patterns of grizzly bear occupancy and density using measures of spatial autocorrelation to assess relationships between occupancy and density and landscape processes related to anthropogenic disturbance and topography. By examining the spatial relationships between predicted grizzly bear occupancy-abundance estimates over a decade, I was able to provide a better understanding how observed patterns are influenced by disturbance and identify important habitat. Occupancy models showed the average occupancy probability decreased slightly (0.35 to 0.34), despite observed increases in grizzly bear population (36.0 to 71.3 individuals) over a decade. However, spatial patterns of occupancy showed previously unoccupied cells in eastern portions of the study area were colonized from 2004 to 2014. Male occupancy was negatively related to anthropogenic disturbance, including cutblocks and all disturbance, compared to females. Anthropogenic disturbance had an increased influence over time, highlighting the need to consider cumulative effects in occupancy monitoring. Spatial patterns of occupancy and density estimates were similar, with clusters of high occupancy and density occurring where terrain is complex and human access is limited. These areas may act as important source habitat for the population with dispersers occupying potential sink habitats where disturbance and mortality are higher. The occupancy modelling framework and results provide a better understanding of the impacts of anthropogenic disturbance on grizzly bear occupancy and population persistence for regulatory bodies, wildlife managers, and industry, which will contribute to the conservation of grizzly bears and other large carnivores.

Intra-vulnerabilities: An Artistic Strategy for Co-creating Culture and Policy with Communities, Funders and Artists
Creators: name: Defrin, Carolyn
Publisher: name: London South Bank University
Year: 2021

description: Funding arts and cultural activity for socially and economically vulnerable communities in the UK carries a deeply embedded practice of culture as compensation. With a tendency to measure the success of these activities through models of impact constructed by funders, such cultural programmes can omit community knowledge and subsequently further their marginalisation. This thesis investigates whether and how funders, artists, and communities can disrupt these one-sided instrumental approaches, by working together towards co-creating culture and policy. It does so specifically through artistic practice as research (PaR)- interrogating a participatory, transdisciplinary installation practice as a productive site for embodying new relationships between those giving and those receiving. As funders, artists and communities performatively shift between expertise and learning, the thesis proposes that the interdependence of their respective sets of knowledge enacts a more equitable policy process for cultural programming in service of a spectrum of socio-economic, creative and aesthetic needs. Underpinned by Karen Barad’s ‘intra-active agential realism,’ the thesis develops a concept of ‘intra-vulnerabilities’, whereby vulnerability is a positive term, extending beyond its usual placement within marginalised communities to include a range of differentiated, circumstantial vulnerabilities amongst funders and artists. As all three parties participate in five iterative PaR projects, vulnerabilities manifest in personal reflection, listening, dialogue, acts of art-making and recognition of a ‘mutual entailment’ in social inequities. Integrating Rosalyn Diprose’s reframing of generosity as a multi-directional landscape of giving, the concept of intra-vulnerabilities (as generated specifically within artistic practice) manifests a valuable interdependence between nuanced and changing vulnerabilities across the provision spectrum that can not only inform but enact policy. Developed in collaboration with Hammersmith United Charities, a 400 year-old housing and community grants giving organisation, the PaR projects ultimately inform and produce an artistic strategy for co-creating culture and policy. An online portfolio of the practice manifests in tandem with the writing, supporting the thesis’ contribution to new knowledge in asserting artistic practice as a key component for artistic policy: https://www.carolyndefrin.com/onlineportfolio . This online portfolio is additionally submitted on a DVD to accompany the written thesis.

description: It is expected that thermalization may be described within gauge/gravity duality by considering time-dependent configurations on the gravity side of the correspondence, for instance a gravitational collapse of a matter configuration in Anti-de Sitter space. As a step towards the ambitious goal of describing such a configuration, we investigate a simple time-dependent toy model in which a mirror moves in the radial direction of Anti-de Sitter space. For this configuration, we establish a procedure for calculating two-point functions of scalar fluctuations, based on a WKB approximation. We test our method on two sample trajectories for the mirror, and find that the singularity structure of the two-point functions is in agreement with geometric optics.

description: The eccentric orbits of the known extrasolar giant planets provide evidence that most planet-forming environments undergo violent dynamical instabilities. Here, we numerically simulate the impact of giant planet instabilities on planetary systems as a whole. We find that populations of inner rocky and outer icy bodies are both shaped by the giant planet dynamics and are naturally correlated. Strong instabilities -- those with very eccentric surviving giant planets -- completely clear out their inner and outer regions. In contrast, systems with stable or low-mass giant planets form terrestrial planets in their inner regions and outer icy bodies produce dust that is observable as debris disks at mid-infrared wavelengths. Fifteen to twenty percent of old stars are observed to have bright debris disks (at wavelengths of ~70 microns) and we predict that these signpost dynamically calm environments that should contain terrestrial planets.

description: Nel presente lavoro di tesi si incentra sulla lettura ad alta voce. Si indagano gli effetti di un breve percorso di potenziamento differenziato sulle abilità di decodifica di allievi di 4a e 5a elementare. Si analizzano inoltre gli errori di decodifica più frequenti in bambini di 4a e 5a elementare. Agli scolari è stato proposto di creare un audiolibro del libro di Pippi Calzelunghe di Astrid Lindgren e di compiere delle attività mirate nel migliorare le loro capacità di decodifica e comprensione del testo, differenziate soprattutto per anno scolastico. I dati raccolti sono stati raccolti attraverso prove di decodifica e comprensione svolte attraverso l’utilizzo di un tablet. Il tutto è stato analizzato qualitativamente. I risultati hanno mostrato che l’intervento didattico proposto ha avuto influenza positiva per alcuni allievi mentre per altri non si sono osservati cambiamenti evidenti. Inoltre, la tempistica ridotta si è rivelata un ostacolo nell’ apprendimento. Un’analisi esplorativa preliminare degli errori di decodifica più frequenti ha evidenziato una prevalenza negli errori di sostituzione/trasformazione di non parole in parole e la sostituzione di fonemi.

description: Let $p:F\to G$ be a morphism of stacks of positive \emph{virtual} relative dimension $k$ and let $γ\in H^k(F)$. We give sufficient conditions for $p_*γ\cdot[F]^{virt}$ to be a multiple of $[G]^{virt}$. We apply this result to show an analogue of the conservation of number for virtually smooth families. We show implications to Gromov-Witten invariants and give a new proof of a theorem of Marian, Oprea and Pandharipande which compares the virtual classes of moduli spaces of stable maps and moduli spaces of stable quotients.

description: Multi-layer graphene on the carbon face of silicon carbide is an intriguing electronic system which typically consists of a stack of ten or more layers. Rotational stacking faults in this system dramatically reduce inter-layer coherence. In this article we report on the influence of inter-layer interactions, which remain strong even when coherence is negligible, on the Fermi liquid properties of charged graphene layers. We find that inter-layer interactions increase the magnitudes of correlation energies and decrease quasiparticle velocities, even when remote-layer carrier densities are small, and that they lessen the influence of exchange and correlation on the distribution of carriers across layers.

description: Signals are emerging pieces of information relevant to a given context and offer potential for strategic advantage in a multitude of domains. However, sorting the signal from noise on large textual data is a very tedious process for humans. We introduce a scalable approach that extracts signals from hundreds of crawled sources and maps their metadata to a knowledge graph by exploiting state-of-the-art neural models for natural language understanding.

description: Observations at mas-resolution scales and high dynamic range hold a central place in achieving, for instance, the spectroscopic characterization of exo-Earths or the detailed mapping of their protoplanetary disc birthplace. Ground or space-based multi-aperture infrared interferometry is a promising technique to tackle these goals. But significant efforts still need to be undertaken to achieve a simplification of these instruments if we want to combine the light from a large number of telescopes. Integrated-optics appears as an alternative to the current conventional designs, especially if its use can be extended to a higher number of astronomical bands. This article reports for the first time the experimental demonstration of the feasibility of an integrated-optics approach to mid-infrared beam combination for single-mode stellar interferometry. We have fabricated a 2-telescope beam combiner prototype integrated on a substrate of chalcogenide glasses, a material transparent from 1 to 14 um. We have developed laboratory tools to characterize the modal properties and the interferometric capabilities of our device. We obtain fringes at 10 um and measure a mean contrast V=0.981 \pm 0.001 with high repeatability over one week and high stability over 5h. We show experimentally - as well as on the basis of modeling considerations - that the component has a single-mode behavior at this wavelength, which is essential to achieve high-accuracy interferometry. From previous studies, the propagation losses are estimated to 0.5 dB/cm for such components. We also discuss possible issues that may impact the interferometric contrast. The IO beam combiner performs well at 10. We also anticipate the requirement of a better matching between the numerical apertures of the component and the (de)coupling optics to optimize the total throughput. The next step foreseen is the achievement of wide-band interferograms.

description: In this short paper, the authors report a new computational approach in the context of Density Functional Theory (DFT). It is shown how it is possible to speed up the self-consistent cycle (iteration) characterizing one of the most well-known DFT implementations: FLAPW. Generating the Hamiltonian and overlap matrices and solving the associated generalized eigenproblems $Ax = λBx$ constitute the two most time-consuming fractions of each iteration. Two promising directions, implementing the new methodology, are presented that will ultimately improve the performance of the generalized eigensolver and save computational time.

description: We study the star formation histories (SFH) and stellar populations of 213 red and 226 blue nearly face-on low surface brightness disk galaxies (LSBGs), which are selected from the main galaxy sample of Sloan Digital Sky Survey (SDSS) Data Release Seven (DR7). We also want to compare the stellar populations and SFH between the two groups. The sample of both red and blue LSBGs have sufficient signal-to-noise ratio in the spectral continua. We obtain their absorption-line indices (e.g. Mg_2, Hδ_A), D_n(4000) and stellar masses from the MPA/JHU catalogs to study their stellar populations and SFH. Moreover we fit their optical spectra (stellar absorption lines and continua) by using the spectral synthesis code STARLIGHT on the basis of the templates of Simple Stellar Populations (SSPs). We find that red LSBGs tend to be relatively older, higher metallicity, more massive and have higher surface mass density than blue LSBGs. The D_n(4000)-Hδ_A plane shows that perhaps red and blue LSBGs have different SFH: blue LSBGs are more likely to be experiencing a sporadic star formation events at the present day, whereas red LSBGs are more likely to form stars continuously over the past 1-2 Gyr. Moreover, the fraction of galaxies that experienced recent sporadic formation events decreases with increasing stellar mass. Furthermore, two sub-samples are defined for both red and blue LSBGs: the sub-sample within the same stellar mass range of 9.5 <= log(M_\star/M_\odot) <= 10.3, and the surface brightness limiting sub-sample with μ_0(R) <= 20.7 mag arcsec^{-2}. They show consistent results with the total sample in the corresponding relationships, which confirm that our results to compare the blue and red LSBGs are robust.

IPSC-derived GRN-mutant astrocytes delay excitatory electrical development of neurons in a non-cell autonomous manner
Creators: name: Lee, Christopher
Publisher: name: University of British Columbia
Year: 2021

description: Frontotemporal dementia (FTD) refers to a group of neurodegenerative disorders that are characterized by pathology predominantly localized to the frontal and temporal lobes. FTD is the second leading cause of early-onset dementia behind Alzheimer’s Disease, and there are currently no disease-modifying treatments available. Approximately 40% of FTD cases are familial, and 25% of these are caused by heterozygous loss of function mutations in the gene encoding for progranulin (PGRN), GRN. Since its discovery almost 15 years ago, a plethora of research has attempted to explain the mechanisms for how loss of PGRN leads to FTD, but an entire picture remains unclear. Evidence from murine models has in the past suggested that astrocytes, the main supporting cells of the brain, do not secrete PGRN; however, more recent analysis has shown astrocyte PGRN expression in both murine and human cells. It has also been shown that mutations in MAPT – another leading cause of familial FTD – greatly alters astrocyte gene expression which leads to subsequent non-cell autonomous effects on neurons. In this study, we utilized human induced pluripotent stem cell (hiPSC)-derived neural tissue carrying a homozygous GRN R493X-/- knock-in mutation to investigate in vitro whether GRN mutant astrocytes have a non-cell autonomous effect on neurons. Using microelectrode array analysis, we demonstrated that GRN R493X-/- astrocytes impact neuron maturation by significantly delaying excitatory electrical development. Histologically, neurons during the delay showed a decrease in GABAergic synaptic markers while also showing an increase in glutaminergic synaptic markers. We also demonstrate that this effect is due in-part due to soluble factors, and that GRN mutation alters neurotrophic factor secretion in astrocytes. Overall, this work represents the first study investigating astrocyte-induced neuronal pathology in GRN mutant hiPSCs, and supports the hypothesis of astrocyte involvement in the progression of FTD.

description: In this paper we describe a uniform analysis of eight transits and eleven secondary eclipses of the extrasolar planet GJ 436b obtained in the 3.6, 4.5, and 8.0 micron bands using the IRAC instrument on the Spitzer Space Telescope between UT 2007 June 29 and UT 2009 Feb 4. We find that the best-fit transit depths for visits in the same bandpass can vary by as much as 8% of the total (4.7 sigma significance) from one epoch to the next. Although we cannot entirely rule out residual detector effects or a time-varying, high-altitude cloud layer in the planet's atmosphere as the cause of these variations, we consider the occultation of active regions on the star in a subset of the transit observations to be the most likely explanation. We reconcile the presence of magnetically active regions with the lack of significant visible or infrared flux variations from the star by proposing that the star's spin axis is tilted with respect to our line of sight, and that the planet's orbit is therefore likely to be misaligned. These observations serve to illustrate the challenges associated with transmission spectroscopy of planets orbiting late-type stars; we expect that other systems, such as GJ 1214, may display comparably variable transit depths. Our measured 8 micron secondary eclipse depths are consistent with a constant value, and we place a 1 sigma upper limit of 17% on changes in the planet's dayside flux in this band. Averaging over the eleven visits gives us an improved estimate of 0.0452% +/- 0.0027% for the secondary eclipse depth. We combine timing information from our observations with previously published data to produce a refined orbital ephemeris, and determine that the best-fit transit and eclipse times are consistent with a constant orbital period.

description: Bourbon, or whiskey, production in Kentucky has been estimated to double within the next five years and an increase in the main by-product from bourbon distillation, stillage. Stillage is composed mostly of water along with the fermented grains after distillation. Stillage is expensive to dispose of and difficult to store due to the high biodegradability, posing a risk to the environment given the low pH and high chemical oxygen demand (COD). Anaerobic digestion has been identified as a potential solution for stillage valorization, but little research has been performed. Stillage from different mash bills has varying physicochemical properties, total solids (TS), volatile solids (VS), pH, and minerals and macronutrients. Distilleries employ varying distillation parameters and coupled with the heterogeneous makeup of the stillage from mash bills, is thought to have an impact on the biomethane potential of stillage. With a minimum methane production of 291.17±3.45 NmL/g VS and a maximum methane production of 419.19 ± 2.61 NmL/g VS out of 10 stillage samples from four distilleries with a food to microbe ratio of 1 g VS/ g VS and an organic loading rate (OLR) of 10 g VS/L, mash bill and distillation parameters were determined to impact stillage biomethane potential.

Function and form of gestures in a collaborative design meeting

Publisher: name: arXiv
Year: 2010
Subjects: subject: Human-Computer Interaction (cs.HC)
subject: FOS: Computer and information sciences

description: This paper examines the relationship between gestures' function and form in design collaboration. It adopts a cognitive design research viewpoint. The analysis is restricted to gesticulations and emblems. The data analysed come from an empirical study conducted on an architectural design meeting. Based on a previous analysis of the data, guided by our model of design as the construction of representations, we distinguish representational and organisational functions. The results of the present analysis are that, even if form-function association tendencies exist, gestures with a particular function may take various forms, and particular gestural movements as regards form can fulfil different functions. Reconsidering these results and other research on gesture, we formulate the assumption that, if formal characteristics do not allow differentiating functional gestures in collaboration, context-dependent, semantic characteristics may be more appropriate. We also envision the possibility that closer inspection of the data reveal tendencies of another nature.

description: Let $(M,ω)$ be a symplectic manifold admitting a metaplectic structure (a symplectic analogue of the Riemannian spin structure) and a torsion-free symplectic connection $\nabla.$ Symplectic Killing spinor fields for this structure are sections of the symplectic spinor bundle satisfying a certain first order partial differential equation and they are the main topic of this paper. We derive a necessary condition satisfied by a symplectic Killing spinor field. The advantage of this condition consists in the fact that it is expressed by a zeroth order operator. This condition helps us substantionally to compute the symplectic Killing spinor fields for the standard symplectic vector spaces and the round sphere $S^2$ equipped with the volume form of the round metric.

description: We construct a qubit algebra from field creation and annihilation operators acting on a global vacuum state. Particles to be used as qubits are created from the vacuum by a near-deterministic single particle source. Our formulation makes the space-time dependence of the qubits explicit, preparing the way for quantum computation within a field framework. The method can be generalized to deal with interacting qubits whose wavepackets are not perfectly matched to each other. We give an example of how to calculate the Heisenberg evolution of a simple two-qubit circuit, taking expectation values in the field vacuum state.

description: We present follow-up observations to those of Geballe & Oka (2010), who found high column densities of H3+ ~100 pc off of the Galactic center (GC) on the lines of sight to 2MASS J17432173-2951430 (J1743) and 2MASS J17470898-2829561 (J1747). The wavelength coverages on these sightlines have been extended in order to observe two key transitions of H3+, R(3,3)l and R(2,2)l, that constrain the temperatures and densities of the environments. The profiles of the H3+ R(3,3)l line, which is due only to gas in the GC, closely matches the differences between the H3+ R(1,1)l and CO line profiles, just as it does for previously studied sightlines in the GC. Absorption in the R(2,2)l line of H3+ is present in J1747 at velocities between -60 and +100 km/s. This is the second clear detection of this line in the interstellar medium after GCIRS 3 in the Central Cluster. The temperature of the absorbing gas in this velocity range is 350 K, significantly warmer than in the diffuse clouds in other parts of the Central Molecular Zone. This indicates that the absorbing gas is local to Sgr B molecular cloud complex. The warm and diffuse gas revealed by Oka et al. (2005) apparently extends to ~100 pc, but there is a hint that its temperature is somewhat lower in the line of sight to J1743 than elsewhere in the GC. The observation of H3+ toward J1747 is compared with the recent Herschel observation of H2O+ toward Sgr B2 and their chemical relationship and remarkably similar velocity profiles are discussed.
