description: The unprecedented events that worldwide population experienced during year 2020 due to the COVID-19 pandemic, resulted in the formation of numerous challenges across the majority of aspects of every day life. Manufacturing industries and supply chain networks faced a unique decostruction during this period due to restrictions created by global or local lockdowns. Reduction of human resources availability and transportation restrictions linked with the extreme and rapid increase of demand for medical supplies led manufactring related activities to reach their limits. Moreover, the non flexible manufacturing methods that are employed for the production of this type of equipment as well as the delayed delivery of products that are used as raw material at the early production stages, resulted in market shortage of medical supplies while demand constantly growing. Additive Manufacturing was used for the immediate production of plastic/metal medical equipment, taking advantage of reverse engineering, process flexibility and commercialization of printing devices. Small and large enteprises in cooperation with individuals have been organized into Local Hubs in order to reduce the transportation time and accelerate the supply of the required equipment at local hopitals until the the non flexible production lines manage to produce the desired production volume under the required production rate. This study aims to identify reasons why traditional manufacturing facilies faced such difficulties in the production of medical equipment and to propose a framework where Additive Manufacturing methods can be used for the immediate, local and low volume production of the desired product, giving time to non easily adjustable industries to initiate the mass production.

description: Artificial Intelligence (AI) is showing its strength worldwide in the healthcare sector. Today, in the aftermath of the COVID-19 pandemic, the help of technology appears to be relevant to keep the increase in new infections stable and help medical staff in treatment. Therefore, this paper aims to investigate how AI can be employed against COVID-19 outbreak. Using a multiple case study approach, researchers find out the following insights. First, AI could be used for drugs discovery and knowledge sharing, tracking and prediction, clinical decision making and diagnosis, social distancing and medical chatbots. Second, this paper provides an in-depth analysis of international best practice for tracking contacts and social distance applications. Third, AI technologies could have a transversal impact, also focusing on prevention strategies as a new corporate social responsibility vein. In the end, this paper has theoretical and managerial implications, too. On the theoretical side, we contribute to the extensive discussion about AI and healthcare considering COVID-19 outbreak. On the practical side, we provide medical personnel and policymakers with a tool to understand artificial intelligence and focus investment choices in the practical applications analysed.

description: Dysarthric speech recognition (DSR) presents a formidable challenge due to inherent inter-speaker variability, leading to severe performance degradation when applying DSR models to new dysarthric speakers. Traditional speaker adaptation methodologies typically involve fine-tuning models for each speaker, but this strategy is cost-prohibitive and inconvenient for disabled users, requiring substantial data collection. To address this issue, we introduce a prototype-based approach that markedly improves DSR performance for unseen dysarthric speakers without additional fine-tuning. Our method employs a feature extractor trained with HuBERT to produce per-word prototypes that encapsulate the characteristics of previously unseen speakers. These prototypes serve as the basis for classification. Additionally, we incorporate supervised contrastive learning to refine feature extraction. By enhancing representation quality, we further improve DSR performance, enabling effective personalized DSR. We release our code at https://github.com/NKU-HLT/PB-DSR.

description: Aims: Our objectives were first to evaluate the possibility for using the NUV absorption as diagnostics of hydrated minerals based on the recent datasets of primitive asteroids and hydrated carbonaceous chondrites, and second to investigate the reflectance spectrophotometry of the primitive asteroids in the NUV as functions of heliocentric distance and size. Methods: The NUV and visible reflectance spectrophotometry of more than 9,000 primitive asteroids was investigated using two spectrophotometric surveys, the Eight Color Asteroid Survey (ECAS) and the Sloan Digital Sky Survey (SDSS), which cover wavelengths down to 0.32 um and 0.36 um, respectively. We classified asteroids from the main asteroid belt, the Cybele and Hilda zones, and Jupiter Trojans based on Tholen's taxonomy and described the statistical distribution of primitive asteroid types. We also examined the relationship of the NUV, 0.7 um, and 2.7 um absorptions among primitive asteroids and hydrous carbonaceous chondrites CI and CM. Results: We found strong correlations between the NUV and the OH-band (2.7 um) absorptions for primitive asteroids and hydrated meteorites, suggesting the NUV absorption can be indicative of hydrated silicates. Moreover, there is a great difference in the NUV absorption between the large asteroids (diameter d > 50 km) and small asteroids (d < 10 km) in the taxonomic distribution. The taxonomic distribution of asteroids differs between the inner main belt and middle-outer main belt. Notably, the C types are dominating large members through the main belt and the F types are dominating small asteroids of the inner main belt. The asteroids beyond the main belt consist mostly of P and D types, although P types are common everywhere in the main belt. The peculiar distribution of F types might indicate a different formation reservoir or displacement process of F types in the early Solar System.

description: Potato (Solanum tuberosum L.) is one of the most important food crops worldwide. Current potato varieties are highly susceptible to drought stress. In view of global climate change, selection of cultivars with improved drought tolerance and high yield potential is of paramount importance. Drought tolerance breeding of potato is currently based on direct selection according to yield and phenotypic traits and requires multiple trials under drought conditions. Marker‐assisted selection (MAS) is cheaper, faster and reduces classification errors caused by noncontrolled environmental effects. We analysed 31 potato cultivars grown under optimal and reduced water supply in six independent field trials. Drought tolerance was determined as tuber starch yield. Leaf samples from young plants were screened for preselected transcript and nontargeted metabolite abundance using qRT‐PCR and GC‐MS profiling, respectively. Transcript marker candidates were selected from a published RNA‐Seq data set. A Random Forest machine learning approach extracted metabolite and transcript markers for drought tolerance prediction with low error rates of 6% and 9%, respectively. Moreover, by combining transcript and metabolite markers, the prediction error was reduced to 4.3%. Feature selection from Random Forest models allowed model minimization, yielding a minimal combination of only 20 metabolite and transcript markers that were successfully tested for their reproducibility in 16 independent agronomic field trials. We demonstrate that a minimum combination of transcript and metabolite markers sampled at early cultivation stages predicts potato yield stability under drought largely independent of seasonal and regional agronomic conditions.

Renormalisation group and critical correlation functions in dimension four
Creators: name: Tomberg, Alexandre
Publisher: name: University of British Columbia
Year: 2015

description: Critical phenomena and phase transitions are important subjects in statistical mechanics and probability theory. They are connected to the phenomenon of universality that makes the study of mathematically simple models physically relevant. Examples of such models include ferromagnetic spin systems such as the Ising, O(n) and n-component |φ|⁴ models, but also the self-avoiding walk that has been observed to formally correspond to a "zero-component" spin model by de Gennes. Our subject in this thesis is the extension and application of a rigorous renormalisation group method developed by Bauerschmidt, Brydges and Slade to study the critical behaviour of the continuous-time weakly self-avoiding walk and of the n-component |φ|⁴ model on the 4-dimensional square lattice ℤ⁴. Although a "zero-component" vector is mathematically undefined (at least naively), we are able to interpret the weakly self-avoiding walk in a mathematically rigorous manner as the n = 0 case of the n-component |φ|⁴ model, and provide a unified treatment of both models. For the |φ|⁴ model, we determine the asymptotic decay of the critical correlation functions including the logarithmic corrections to Gaussian scaling, for n ≥ 1. This extends previously known results for n = 1 to all n ≥ 1, and also observes new phenomena for n > 1, all with a new method of proof. For the continuous-time weakly self-avoiding walk, we determine the decay of the critical generating function for the "watermelon" network consisting of p weakly mutually- and self-avoiding walks, for all p ≥ 1, including the logarithmic corrections. This extends a previously known result for p = 1, for which there is no logarithmic correction, to a much more general setting.

description: This paper focuses mainly on the investigation of the fluid flow and convective heat transfer inside a two-dimensional double constricted channel employing the Lattice Boltzmann Method with multiple relaxation times (LBM-MRT). To describe the fluid behavior and the heat transfer, a detailed study was performed to interpret the effect of the constriction part and the Reynolds number variation using the D2Q9 and the D2Q5 model. A detailed study was performed to interpret the effect of the constriction part and the Reynolds number variation. The results are presented in the form of streamlines, isotherms, and averaged Nussel numbers.

description: We report a theoretical investigation of effects of Mn and Co substitution in the transition metal sites of the kagome-lattice ferromagnet, Fe3Sn2. Herein, hole- and electron-doping effects of Fe3Sn2 have been studied by density-functional theory calculations on the parent phase and on the substituted structural models of Fe3-xMxSn2 (M = Mn, Co; x = 0.5, 1.0). All optimized structures favor the ferromagnetic ground state. Analysis of the electronic density of states (DOS) and band structure plots reveals that the hole (electron) doping leads to a progressive decrease (increase) in the magnetic moment per Fe atom and per unit cell overall. The high DOS is retained nearby the Fermi level in the case of both Mn and Co substitutions. The electron doping with Co results in the loss of nodal band degeneracies, while in the case of hole doping with Mn emergent nodal band degeneracies and flatbands initially are suppressed in Fe2.5Mn0.5Sn2 but re-emerge in Fe2MnSn2. These results provide key insights into potential modifications of intriguing coupling between electronic and spin degrees of freedom observed in Fe3Sn2.

description: Great megathrust earthquakes arise from the sudden release of energy accumulated during centuries of interseismic plate convergence. The moment deficit (energy available for future earthquakes) is commonly inferred by integrating the rate of interseismic plate locking over the time since the previous great earthquake. But accurate integration requires knowledge of how interseismic plate locking changes decades after earthquakes, measurements not available for most great earthquakes. Here we reconstruct the post-earthquake history of plate locking at Guafo Island, above the seismogenic zone of the giant 1960 (M-w = 9.5) Chile earthquake, through forward modeling of land-level changes inferred from aerial imagery (since 1974) and measured by GPS (since 1994). We find that interseismic locking increased to similar to 70% in the decade following the 1960 earthquake and then gradually to 100% by 2005. Our findings illustrate the transient evolution of plate locking in Chile, and suggest a similarly complex evolution elsewhere, with implications for the time- and magnitude-dependent probability of future events.

This work investigates post-hoc correction of ASR transcripts with LLMs. To avoid introducing errors into likely accurate transcripts, we propose a range of confidence-based filtering methods. Our results indicate that this can improve the performance of less competitive ASR systems.

Professional uncertainty in providing dental care for children with special health care needs among general dentists in British Columbia
Creators: name: Sun, Shan
Publisher: name: University of British Columbia
Year: 2015

description: Objective: The aim of this study was to determine whether scientific (knowledge base), practical (clinical infra-structure) or personal (sense of social justice) sources of uncertainty among British Columbia general dentists posed the greatest barriers to their ability to treat children with special health care needs (CSHCN). Methods: A 74-item self-administered electronic questionnaire was distributed to a random sample of 1200 general dentists registered with the British Columbia Dental Association. Variability in clinical practice (examine, examine and refer, refer) was assessed using three case scenarios featuring CSHCN with a 1) behavioral difficulty (autism spectrum disorder), 2) physical disability (bleeding disorder) or 3) combination (cerebral palsy). Respondents were asked to use a five-point Likert-type scale to rate uncertainty levels from scientific, practical and personal sources in each case scenario. One-sample t-tests were used to compare differences between examination/refer for examination and treat/refer for treatment group pairs. All items in the scientific, practical and personal domains were tested using multivariate analyses (logistic regression) for all three cases. Data was analyzed and classified based on a novel taxonomical approach. Results: The response rate was 20.2% (n=226). A higher percentage of dentists were willing to examine and treat a child with a bleeding disorder (59.7%) or cerebral palsy (63.0%) compared to a child with autism (54.5%). Among those who would refer, the most significant reported sources of uncertainty in general are scientific (knowledge of management, ability to diagnose disease) and practical sources (staff training, inadequate facilities, busy practice). Conclusions: While the majority of general dentists showed interest and desire to provide care for CSHCN, scientific and practical uncertainty are significant factors affecting their ability to provide care. Recognizing the presence of uncertainty in dental care can inform policy changes to help dentists either decrease reducible uncertainties or cope with those that are irreducible. Implementation of increased undergraduate curriculum hours and hands on experience with CSHCN as well as expanded coverage of public and private dental benefits may help reduce barriers to care for CSHCN, in particular for those with conditions such as autism spectrum disorder.

description: We report that planar CuO_2 hole densities in high-T_c cuprates are consistently determined by the Cu-NMR Knight shift. In single- and bi-layered cuprates, it is demonstrated that the spin part of the Knight shift K_s(300 K) at room temperature monotonically increases with the hole density $p$ from underdoped to overdoped regions, suggesting that the relationship of K_s(300 K) vs. p is a reliable measure to determine p. The validity of this K_s(300 K)-p relationship is confirmed by the investigation of the p-dependencies of hyperfine magnetic fields and of spin susceptibility for single- and bi-layered cuprates with tetragonal symmetry. Moreover, the analyses are compared with the NMR data on three-layered Ba_2Ca_2Cu_3O_6(F,O)_2, HgBa_2Ca_2Cu_3O_{8+delta}, and five-layered HgBa_2Ca_4Cu_5O_{12+delta}, which suggests the general applicability of the K_s(300 K)-p relationship to multilayered compounds with more than three CuO_2 planes. We remark that the measurement of K_s(300 K) enables us to separately estimate p for each CuO_2 plane in multilayered compounds, where doped hole carriers are inequivalent between outer CuO_2 planes and inner CuO_2 planes.

description: The complex non-linear processes in multi-dimensional parameter spaces, that are typical for an accelerator, are a natural application for machine learning algorithms. This paper reports on the use of Bayesian optimization for the optimization of the Injection Beam Line (IBL) of the Cooler Synchrotron storage ring COSY at the Forschungszentrum Jülich, Germany. Bayesian optimization is a machine learning method that optimizes a continuous objective function using limited observations. The IBL is composed of 15 quadrupoles and 28 steerers. The goal is to increase the beam intensity inside the storage ring. The results showed the effectiveness of the Bayesian optimization in achieving better/faster results compared to manual optimization.
The Territory without a Map: the Sea as a Narratological Frame and Compass in the "Odyssey"

Year: 2020

description: In this paper, I argue that the sea in Homer’s Odyssey is not the territory suggested by its map, but rather an all-encompassing narratological frame: the sea keeps the isolated locations of Odysseus’ misadventures together. As such the sea in the Odyssey is not just salty, dark-coloured water: it is the continuum in which the narrator’s mind roams, looking for anchor points to which to attach tales and episodes. Searching the virtual space of his imagination, Odysseus presents his series of misadventures and their remote locations as islands in isolation, and uses the sea as an equally virtual space to frame them. For the story-weaving Odysseus, the sea is the fictitious tapestry. And as Teiresias’ warning words show (Od. XI 121-137, repeated in Od. XXIII 265-283), Odysseus somehow has to escape this fiction to find peace, though he cannot escape death coming from it.

description: This paper describes the wave-front correction system developed for the Sunrise balloon telescope, and provides information about its in-flight performance. For the correction of low-order aberrations, a Correlating Wave-Front Sensor (CWS) was used. It consisted of a six-element Shack-Hartmann wave-front sensor (WFS), a fast tip-tilt mirror for the compensation of image motion, and an active telescope secondary mirror for focus correction. The CWS delivered a stabilized image with a precision of 0.04 arcsec (rms), whenever the coarse pointing was better than 90 arcsec peak-to-peak. The automatic focus adjustment maintained a focus stability of 0.01 waves in the focal plane of the CWS. During the 5.5 day flight, good image quality and stability was achieved during 33 hours, containing 45 sequences that lasted between 10 and 45 minutes.
T cell proliferation of South African HIV-exposed uninfected infants
Creators: name: Macgillivray, Duncan Malcolm
Publisher: name: University of British Columbia
Year: 2015

description: Background: Prophylactic perinatal anti-retroviral drugs (ARVs) can effectively prevent mother to child transmission of HIV. Despite escaping HIV infection, HIV-exposed uninfected (HEU) infants suffer greater morbidity and mortality from other infections compared to unexposed (UE) peers. The reason for these worse outcomes is unknown, but could be adverse haematologic or immunologic effects of ARVs and/or exposure to maternal HIV infection. This study investigated a cohort of HEU and UE infants to determine whether perinatal exposure to maternal HIV infection and ARVs alter (1) the haematological compartment and/or (2) T cell responsiveness. Methods: In Cape Town, South Africa, clinical data as well as blood samples were collected from HEU (n=25) and UE (n=26) participants over the first 2 years of life. Samples from 2, 6, 12, 16, 52, 78, and 104 weeks of life were assessed by complete blood count (CBC). Peripheral blood mononuclear cells (PBMCs) were cryopreserved for in vitro assays. PBMCs from 6 and 12 weeks were stained with Oregon Green and stimulated with antibodies to CD3 (the T cell receptor; TCR) and CD28 for 7 days. CD4+ & CD8+ T cell subsets, proliferation and intra-cellular cytokine production were measured using flow cytometry. Cell counts and flow cytometry data were compared between groups using Wilcoxon tests. Results: All but two HEU were exposed to ARV regimens that included azidothymidine (AZT). Haematological differences were observed in HEU subjects at 2 and 6 weeks of life. However, these differences were restricted to erythrocytes and HEU CBC values were within the normal range. No statistical differences were detected between HEU and UE participants with respect to T cell frequencies, proliferation, or intracellular cytokine staining following TCR stimulation. Conclusions: We observed transient haematological differences in erythrocytes of HEU participants during early infancy, which was likely the result of AZT toxicity. Response of PBMCs to direct TCR stimulation did not reveal any differences in T cell proliferation. This finding contrasts reports of increased HEU T cell proliferation to mitogens that involve cross-linking of antigen-presenting cells (APCs) with T cells, suggesting that HIV and/or ARV exposure may impact APCs more than intrinsic T cell function.

description: This is a Protection Profile (PP) according to the Common Criteria (CC). The PP serves as "base PP" of the modular PP. Note: The PP is a research output from the certMILS project.
 That is, despite being a sincere effort that we have submitted to further feedback (https://zenodo.org/record/2541464), it has not undergone Common Criteria certification. Whereas a Security Target (ST) always describes a specific Target of Evaluation (TOE), a Protection Profile (PP) is intended to describe a TOE type - in this case a Separation Kernel (SK) operating system. The same PP may therefore be used as a template for many different STs employed in different Common Criteria evaluations. This "Base PP" can be extended using defined "PP Modules" that are produced as certMILS deliverable D2.2 (https://www.zenodo.org/record/2586507). These PP modules describe optional security functionality of an SK (that may cover additional threats). Together with the base PP, these build a “PP Configuration”. The base PP first provides an overview of the type of TOE. The relevant normative text is identified (Common Criteria version 3.1 revision 5) and the security problem is defined. The resolution of that security problem is achieved through security objectives for the TOE and its environment. These objectives are re-expressed as formal security functional requirements that the TOE must implement and as assumptions that the environment must satisfy. A PP is a living document, so this deliverable should be perceived as a snapshot of the certMILS partners at M16 that will be constantly extended, based on the internal and external feedback.

description: The Milky Way accreted several smaller satellite galaxies in its history. These mergers added stars and gas to the Galaxy and affected the properties of the pre-existing stellar populations. Stellar chemical abundances and ages are needed to establish the chronological order of events that occur before, during, and after such mergers. We report precise ages ($\sim$6.5%) and chemical abundances for the Titans, a sample of old metal-poor dwarfs and subgiants with accurate atmospheric parameters. We also obtain ages with an average precision of 10% for a selected sample of dwarf stars from the GALAH survey. We used these stars, located within $\sim$1 kiloparsec of the Sun, to analyse the chronology of the chemical evolution of in-situ and accreted metal-poor stellar populations. We determined ages by isochrone fitting. For the Titans, we determined abundances of Mg, Si, Ca, Ti, Ni, Ba, and Eu using spectrum synthesis. The [Mg/Fe] abundances of the GALAH stars were re-scaled to be consistent with the abundances of the Titans. We separated stellar populations by primarily employing chemical abundances and orbits. We find that star formation in the so-called Gaia-Enceladus or Gaia-Sausage galaxy, the last major system to merge with the Milky Way, lasted at least 3 billion years and got truncated 9.6 $\pm$ 0.2 billion years ago. This marks with very high precision the last stage of its merging process. We also identified stars of a heated metal-poor in-situ population with virtually null net rotation, probably disturbed by several of the early Milky Way mergers. We show that this population is more metal rich than Gaia-Enceladus at any time. The sequence of events uncovered in our analysis supports the hypothesis that Gaia-Enceladus truncated the formation of the high-$α$ disc and caused the gas infall that forms the low-$α$ disc, in agreement with theoretical predictions.

description: L’articolo propone di ricondurre e legare alcune componenti (narrative e tematiche, ma anche di gameplay e level design) del videogioco The Legend of Zelda: The Wind Waker (Nintendo 2002), a una dimensione più ampia e accostabile all’epica marina. La ricerca è introdotta da una questione definitoria sull’accostamento del concetto di epica ai videogiochi. In seguito ci si sofferma sullo studio di caso, affiancato da altri videogiochi in cui è rintracciabile una avventurosa esplorazione del mare. Il confronto verte in particolare fra Wind Waker e l’Odissea, opera alla quale questo videogioco è stato già accostato in diverse occasioni, senza tuttavia andar mai a fondo sui loro punti di contatto. All’interno della popolare saga The Legend of Zelda, il caso di Wind Waker è l’unico in cui il viaggio dell’eroe protagonista è strettamente intrecciato con l’elemento marittimo, attraverso incontri con mostri marini, naufragi e misteriosi mondi sommersi.

Noticing nature : individual and social benefits of a two-week photography intervention
Creators: name: Passmore, Holli-Anne
Publisher: name: University of British Columbia

description: Bivariate relationships have previously been established between exposure to nature and individual well-being, prosocial behaviour, and a general sense of connectedness, and between a general sense of connectedness and connectedness to nature. However, no model has been proposed to account for the patterning of these bivariate relationships. Research examining the relationship between exposure to nature and materialism is also lacking. The present research addressed these gaps by: a) manipulating the degree to which participants noticed and paid attention to nature over a two-week period; b) measuring participants' levels of post-intervention well-being (i.e., net-positive affect, elevating feelings, and sense of meaning), general connectedness, prosocial behaviour, and materialism; and, c) examining the pattern of relationships between these variables. Participants were randomly assigned to take photographs of either natural or built scenes/features that evoked in them strong emotions, or they were assigned to a no-photograph control condition. Participants uploaded their photos to a research website and indicated what feelings were evoked by the scenes. Following the two-week period, participants completed post-intervention measures of the dependent variables. Results showed that noticing nature over the course of a two-week period had beneficial individual and social effects. Post-intervention levels of well-being (i.e., net-positive affect and feelings related to elevation), general connectedness, and prosocial behaviour were higher for participants in the nature condition, compared to participants in the built and control conditions. These effects were not moderated by trait levels of connectedness to nature or engagement with beauty, nor were they moderated by dosage of nature. Post-intervention levels of sense of meaning and materialism did not differ between conditions. Mediation analyses did not reveal significant mediation pathways.
On radial geodesic forcing of zonal modes

description: The elementary local and global influence of geodesic field line curvature on radial dispersion of zonal modes in magnetised plasmas is analysed with a primitive drift wave turbulence model. A net radial geodesic forcing of zonal flows and geodesic acoustic modes can not be expected in any closed toroidal magnetic confinement configuration, since the flux surface average of geodesic curvature identically vanishes. Radial motion of poloidally elongated zonal jets may occur in the presence of geodesic acoustic mode activity. Phenomenologically a radial propagation of zonal modes shows some characteristics of a classical analogon to second sound in quantum condensates.

description: Exceptional points (EPs) are singular points on a parameter space at which some eigenvalues (scattering poles) and their corresponding eigenmodes coalesce. This study shows the existence of second- and third-order EPs in cylindrical elastic systems with radiation loss. We consider multilayered cylindrical solids under the plane-strain condition placed in a background elastic or acoustic medium. Elastic and acoustic waves propagating in the background media are subject to the radiation loss. We optimize the radii and the material constants of the multilayered solids, such that some scattering poles coalesce on the complex frequency plane. Some numerical experiments are performed to confirm that the coalescence originates from EPs. We expect that this study provides a new approach for enhancing mechanical sensors.

Broad and Luminous [OIII] and [NII] in Globular Cluster ULXs

description: We consider an accretion-disc origin for the broad and luminous forbidden-line emission observed in ultraluminous X-ray (ULX) sources CXOJ033831.8-352604 and XMMU 122939.7+075333 in globular clusters hosted by elliptical galaxies NGC 1399 and NGC 4472, respectively. We will refer to the latter by the globular cluster name RZ2109. The first has strong [OIII] and [NII], the second only [OIII]. Both H$α$ and H$β$ are very weak or undetected in both objects. We assume that the large line widths are due to Keplerian rotation around a compact object and derive expressions for maximum line luminosities. These idealized models require central masses $\gtrsim100$ and $\gtrsim30000\Msun$ for CXOJ033831.8-352604 and RZ2109, respectively. An independent, bootstrap argument for the total disc mass yields, for both systems, $M_{\mathrm{disc}}\gtrsim10^{-4}\Msun$ for a purely metallic disc (and two orders of magnitude larger for solar metallicities). If Roche-lobe overflow is implicated, viscous time-scales are $\gtrsim300$ yr. Standard disc theory then offers another limit on the central masses. Lobe radii for a $\sim1\Msun$ donor are $\gtrsim10^{13}$ cm. We therefore rule out Roche-lobe overflow of a white dwarf in both systems. Red giants could fill the necessary lobes. Whether they are too metal-poor to produce the strong forbidden lines without strong hydrogen emission is unclear.

description: Superfluid dark matter, consisting of self-interacting light particles that thermalize and condense to form a superfluid in galaxies, provides a novel theory that matches the success of the standard $Λ$CDM model on cosmological scales while simultaneously offering a rich phenomenology on galactic scales. Within galaxies, the dark matter density profile consists of a nearly homogeneous superfluid core surrounded by an isothermal envelope. In this work we compute the density profile of superfluid dark matter around supermassive black holes at the center of galaxies. We show that, depending on the fluid equation of state, the dark matter profile presents distinct power-law behaviors, which can be used to distinguish it from the standard results for collisionless dark matter.

The faint extragalactic radio sky
Creators: name: Vernstrom, Tessa
Publisher: name: University of British Columbia
Year: 2015

description: The radio sky covers a large range of sources, from small single galaxies to large clusters of galaxies and the space between them. These sources consist of some of the most powerful objects in the Universe, as well as diffuse weak emitters. Understanding the radio sky tells us about how galaxies have evolved over time, the different kinds of galaxy populations, the star formation history of the Universe, and the role of magnetism, as well as details of large-scale structure and clustering. Advancements in radio telescopes now allow us to push observational limits to new depths, probing fainter galaxies and farther back in cosmic time. We use a multi-pronged approach to examine several aspects of the faint extragalactic radio sky. Using new deep data from the Karl G. Jansky Very Large Array telescope, combined with the confusion analysis technique of P(D), we obtain the deepest estimates of the source count of individual radio galaxies and their contribution to the cosmic radio background temperature. Additionally, these data are used to catalogue the individual galaxies in order to study characteristics such as source size, spectral dependence, galaxy type, and redshift. We then examine the contribution from extended large-scale diffuse emission to the radio sky using data from the Australia Telescope Compact Array. This yields constraints on the total emission from such sources, including galactic halos, galaxy cluster halos and relics, and the inter- and intra-cluster medium. Finally, we investigate the radio angular power spectrum using interferometric data. These measurements show the fluctuations coming from the unresolved radio background as a function of angular scale. Together these studies present the deepest constraints available for the faint radio sky across a range of statistical areas. The measurements obtained here provide constraints on the evolving population of galaxies through their radio emission in order to further our knowledge of galaxy evolution in general.
Tupaia: Palingenesis of a Polynesian Epic Hero

description: Polynesian navigator Tupaia boarded Captain Cook’s Endeavour in Tahiti in 1769, becoming a cultural intermediary and interpreter during the first encounters with the Māori people in Aotearoa. What we know of Tupaia is gathered by several accounts by members of the British expedition, but no Māori or other Polynesian sources have survived after Tupaia’s death in 1770. As part of New Zealand’s “Tuia 250” commemoration in 2019, Tupaia’s story was retold by poet Courtney Sina Meredith and illustrator Mat Tait in The Adventures of Tupaia, a graphic novel which combines historical facts and anecdotes with fictional interpretations of some aspects of Tupaia’s life. In the same year, director Lala Rolls was finishing producing another major artistic work reinterpreting Tupaia’s story, 2020 documentary Tupaia’s Endeavour. This research argues that these creative works are signs that we are now witnessing to Tupaia’s palingenesis as a Polynesian epic hero and it attempts to construct Tupaia’s heroic identity by looking at shared themes between the graphic novel and the film.

Year: 2020

description: Uno dei motivi centrali della Ballata di Rudi di Elio Pagliarani è quello dell’acqua, specialmente nell’immagine del mare. Scopo di questo saggio è cercare di dimostrare l’influenza della Terra desolata di Eliot nella strutturazione dell’opera e, in particolare, nella messa a punto del tema acquatico, ragionando sulle possibilità (e sui modi) dell’epica nella poesia novecentesca e proponendo una lettura ecologista dell’opera di Pagliarani.

description: Nell’estate del 1895 d’Annunzio, in compagnia di alcuni amici, si imbarca sullo yatch di Edoardo Scarfoglio per una vacanza in Grecia; l’avventura si rivela faticosa e scomoda, decisamente poco consona a un «vivere inimitabile». Eppure, pochi anni dopo, quel viaggio non troppo fortunato acquista in Maia una nuova dignità: d’Annunzio lo proietta infatti in una dimensione epica, sovrapponendo a quella di Ulisse la sua figura, come un nuovo eroe che viaggia sul mare alla scoperta di una grecità non archeologica, ma profondamente calata nel mondo moderno.
