description: The merger of two white dwarfs (a.k.a. double degenerate merger) has often been cited as a potential progenitor of type Ia supernovae. Here we combine population synthesis, merger and explosion models with radiation-hydrodynamics light-curve models to study the implications of such a progenitor scenario on the observed type Ia supernova population. Our standard model, assuming double degenerate mergers do produce thermonuclear explosions, produces supernova light-curves that are broader than the observed type Ia sample. In addition, we discuss how the shock breakout and spectral features of these double degenerate progenitors will differ from the canonical bare Chandrasekhar-massed explosion models. We conclude with a discussion of how one might reconcile these differences with current observations.

description: The structural and biological mechanism of a drug material was investigated by spectroscopic techniques and molecular modeling methods. The experimental spectroscopic techniques, namely Fourier Transform Infrared and Fourier Transform Raman spectroscopies are recorded for the structural confirmation and were also compared with computed values. The stability of the compound, the intermolecular and intra molecular interactions is studied using the density functional theory tool Gaussian 16 W. The optimized molecular geometry, vibrational wavenumbers, infrared intensities, and Raman scattering activities are calculated. Natural Bond Orbital analysis has been carried out to explain the charge transfer (or) delocalization of charge due to the intra molecular interactions. The Time dependent-Density functional theory is used to evaluate the excitations between different energy levels, the interpretation which affords good information about D-(-)-alpha-Phenylglycine’s electronic properties with different solvation effects. Reactive sites were also analyzed using topological studies. To explore the biological activities docking studies of D-(-)-alpha-Phenylglycine is performed with Prolactinoma and hyperprolactinemia diseases.

description: Objectives To review the available evidence supporting the validity of algorithms to identify asthma patients in healthcare administrative databases. Methods A systematic literature search was conducted on multiple databases from inception to March 2020 to identify studies that reported the validity of case-finding asthma algorithms applied to healthcare administrative data. Following an initial screening of abstracts, two investigators independently assessed the full text of studies which met the pre-determined eligibility criteria. Data on study population and algorithm characteristics were extracted. A revised version of the Quality Assessment of Diagnostic Accuracy Studies tool was used to evaluate the risk of bias and generalizability of studies. Results: A total of 20 studies met the eligibility criteria. Algorithms which incorporated ≥1 diagnostic code for asthma over a 1-year period appeared to be valid in both adult and pediatric populations (sensitivity ≥ 85%; specificity ≥ 89%; PPV ≥ 70%). The validity was enhanced when: (1) the time frame to capture asthma cases was increased to two years; (2) ≥2 asthma diagnostic codes were considered; and (3) when diagnoses were recorded by a pulmonologist. Algorithms which integrated pharmacy claims data appeared to correctly identify asthma patients; however, the extent to which asthma medications can improve the validity remains unclear. The quality of several studies was high, although disease progression bias and biases related to self-reported data was observed in some studies. Conclusions Healthcare administrative databases are adequate sources to identify asthma patients. More restrictive definitions based on both asthma diagnoses and asthma medications may enhance validity, although further research is required to confirm this hypothesis.

description: To evaluate the cost-effectiveness of mepolizumab added to standard of care (SOC) compared with SOC alone among patients with severe uncontrolled eosinophilic asthma in the Singapore setting. A Markov model with three health states (asthma on mepolizumab and SOC, asthma on SOC alone, and death) was developed from a healthcare system perspective over a lifetime horizon. During each 4-week cycle, patients in the non-death health states could experience asthma exacerbations requiring oral corticosteroid burst, emergency department visit, or hospitalization. Asthma-related mortality following an exacerbation or all-cause mortality could also occur at each cycle. The model was populated using local costs while utilities were derived from international literature. Transition probabilities were obtained from a mixture of Singapore-specific and internationally published data. The base-case analysis comparing mepolizumab plus SOC with SOC alone resulted in an incremental cost-effectiveness ratio (ICER) of SGD335 486 (USD238 195) per quality-adjusted life-year (QALY) gained. Sensitivity analysis demonstrated that the ICER was most sensitive to the price of mepolizumab, followed by the proportion of exacerbations which required hospital intensive care. Despite restricting mepolizumab use to patients with a higher baseline exacerbation rate (3 in the past year) in a scenario analysis, the ICER remained high at SGD238 876 (USD 169 602) per QALY gained. At its current price, mepolizumab is not considered a cost-effective use of healthcare resources in Singapore. Substantial price reductions for mepolizumab are required to improve its cost-effectiveness to an acceptable range. These results will be useful to inform national funding decisions.
The influence of the spheno occipital synchondrosis fusion on craniofacial form

Publisher: name: University of British Columbia
Year: 2020

description: Introduction: Growth of the facial skeleton is integrated to growth of the cranial base. This relationship is highlighted in patients with craniosynostosis syndromes in whom premature fusion of cranial base synchondroses, including the spheno-occipital synchondrosis (SOS), is associated with severe midface deficiency. Objectives: To evaluate the relationship between SOS fusion and craniofacial morphology in non-syndromic individuals – specifically midface projection and skeletal Class III phenotype. Methods: 250 pre-treatment cone-beam computed tomography images were studied from a collection of orthodontic patients’ records, aged 5-11 years (M = 99, F = 151, average age = 8.77 years). SOS fusion was scored using a 6-stage SOS fusion scale utilizing InVivoDental (v6). 3D Slicer (v4.10.2) was used to place three-dimensional landmarks. Error analysis was performed by repeat landmarking of 12 volumes (mean error = 0.23 mm). X, Y, Z coordinates for landmarks were used to determine linear and angular craniofacial measurements. Geometric morphometric (GM) analyses were used to describe facial shape variation. Results: There is a large variation in SOS fusion stage, with older children tending to have a higher fusion stage than younger children. While SOS stage is correlated with subject age, no statistically significant relationships were noted in the age of SOS stages between the Skeletal Class I, II, and III groups for males or females. There were no statistically significant findings of SOS stage as it relates to age or the linear and angular craniofacial measurements in this study, except A Point – Nasion – B point angle being decreased in SOS stage 3 compared to SOS stage 2. The GM analyses suggests that SOS stage, sex, and skeletal class do correlate with craniofacial morphology. Conclusions: This data suggests that younger children with early fusion of the SOS may display a skeletal pattern which is similar to a skeletal Class III morphology. SOS stage is more closely correlated to facial morphology differences of increased mandibular length and transverse facial width. Maxillary projection is also found to be correlated with sex and skeletal class. Further investigation is needed to assess how fusion of the SOS may affect orthodontic and orthopedic treatments for midface deficiency.

description: We present an experimental realization of a moving magnetic trap decelerator, where paramagnetic particles entrained in a cold supersonic beam are decelerated in a co-moving magnetic trap. Our method allows for an efficient slowing of both paramagnetic atoms and molecules to near stopping velocities. We show that under realistic conditions we will be able to trap and decelerate a large fraction of the initial supersonic beam. We present our first results on deceleration in a moving magnetic trap by bringing metastable neon atoms to near rest. Our estimated phase space volume occupied by decelerated particles at final velocity of 50 m/s shows an improvement of two orders of magnitude as compared to currently available deceleration techniques.

description: Inverse probability weights are increasingly used in epidemiological analysis, and estimation and application of weights to address a single bias are well discussed in the literature. Weights to address multiple biases simultaneously (i.e. a combination of weights) have almost exclusively been discussed related to marginal structural models in longitudinal settings where treatment weights (estimated first) are combined with censoring weights (estimated second). In this work, we examine two examples of combined weights for confounding and missingness in a time-fixed setting in which outcome or confounder data are missing, and the estimand is the marginal expectation of the outcome under a time-fixed treatment. We discuss the identification conditions, construction of combined weights and how assumptions of the missing data mechanisms affect this construction. We use a simulation to illustrate the estimation and application of the weights in the two examples. Notably, when only outcome data are missing, construction of combined weights is straightforward; however, when confounder data are missing, we show that in general we must follow a specific estimation procedure which entails first estimating missingness weights and then estimating treatment probabilities from data with missingness weights applied. However, if treatment and missingness are conditionally independent, then treatment probabilities can be estimated among the complete cases.

description: We present first results of a Chandra X-ray observation of the rare oxygen-type Wolf-Rayet star WR 142 (= Sand 5 = St 3) harbored in the young, heavily-obscured cluster Berkeley 87. Oxygen type WO stars are thought to be the most evolved of the WRs and progenitors of supernovae or gamma ray bursts. As part of an X-ray survey of supposedly single Wolf-Rayet stars, we observed WR 142 and the surrounding Berkeley 87 region with Chandra ACIS-I. We detect WR 142 as a faint, yet extremely hard X-ray source. Due to weak emission, its nature as a thermal or nonthermal emitter is unclear and thus we discuss several emission mechanisms. Additionally, we report seven detections and eight non-detections by Chandra of massive OB stars in Berkeley 87, two of which are bright yet soft X-ray sources whose spectra provide a dramatic contrast to the hard emission from WR 142.

description: The Scottish Government is committed to reducing greenhouse gas (GHG) emissions from agriculture as part of Scotland’s target to reach net-zero emissions by 2045. To meet this very challenging target, the sector and Government are likely to have to take steps to ensure uptake of all available emission-reduction technologies and practices, by all farmers. Understanding behavioural change and attitudes will therefore be critical in order to develop policies and work with industry to deliver this goal. This study explores the evidence for factors behind adoption of climate-friendly agricultural practices. It examines interventions to encourage practice change, and the key factors that influence successful adoption.

These conclusions are based on corresponding results for the digamma function ψ:=\Ga'/\Ga. Relations with other relevant results are discussed, as well as the corresponding computational aspects.

description: Lo scopo di questa tesi di bachelor è di capire se, e come, i bambini della scuola dell’Infanzia possano allenare le loro capacità di orientamento spaziale esplorando e osservando il territorio, per contribuire alla creazione di un plastico del comune in cui vivono. Nel corso dell’indagine sono state proposte attività in cui i bambini hanno potuto vivere in prima persona la scoperta del territorio tramite uscite didattiche e attività in aula con l’ausilio di supporti quali carte, immagini e fotografie dei luoghi osservati. Il risultato di questa esperienza è visibile in un plastico strutturato quasi interamente dai bambini. Essi hanno creato gli edifici mancanti e aggiunto via via dei dettagli da inserire. Attraverso l’osservazione e l’analisi dei prodotti ottenuti dai bambini e dai loro comportamenti, è stato possibile trarre le conclusioni necessarie per affermare che le uscite didattiche sono risultate utili per sviluppare l’attenzione ai dettagli, necessari a completare il plastico.

description: Per poter insegnare serenamente e per consentire agli alunni di apprendere e lavorare dignitosamente è essenziale costruire un buon clima di classe. Per vivere bene e sentirsi parte del gruppo classe è necessario collaborare con i compagni, instaurare delle relazioni positive e rispettare le regole per una buona convivenza. Nel seguente elaborato sono stati sondati i possibili effetti positivi che si hanno sul clima di classe approfondendo e favorendo la collaborazione e il rispetto delle regole. Per osservare queste dinamiche sono stati svolti due percorsi didattici, uno sulla collaborazione e uno sul rispetto delle regole, in una terza-quarta elementare, i quali sono stati aperti da un questionario in entrata e chiusi da un questionario in uscita. Questi strumenti hanno permesso di confrontare i dati raccolti prima e dopo gli interventi e di conseguenza di rispondere alla domanda di ricerca. I risultati conseguiti confermano quanto detto dai vari studiosi e ricercatori, tra cui Polito, e dimostrano che le due variabili in questione, se prese in considerazione e consolidate, favoriscono e aiutano a creare un clima di classe positivo.

PAC learnability under non-atomic measures: a problem by Vidyasagar

description: In response to a 1997 problem of M. Vidyasagar, we state a criterion for PAC learnability of a concept class $\mathscr C$ under the family of all non-atomic (diffuse) measures on the domain $Ω$. The uniform Glivenko--Cantelli property with respect to non-atomic measures is no longer a necessary condition, and consistent learnability cannot in general be expected. Our criterion is stated in terms of a combinatorial parameter $\VC({\mathscr C}\,{\mathrm{mod}}\,ω_1)$ which we call the VC dimension of $\mathscr C$ modulo countable sets. The new parameter is obtained by "thickening up" single points in the definition of VC dimension to uncountable "clusters". Equivalently, $\VC(\mathscr C\moddω_1)\leq d$ if and only if every countable subclass of $\mathscr C$ has VC dimension $\leq d$ outside a countable subset of $Ω$. The new parameter can be also expressed as the classical VC dimension of $\mathscr C$ calculated on a suitable subset of a compactification of $Ω$. We do not make any measurability assumptions on $\mathscr C$, assuming instead the validity of Martin's Axiom (MA). Similar results are obtained for function learning in terms of fat-shattering dimension modulo countable sets, but, just like in the classical distribution-free case, the finiteness of this parameter is sufficient but not necessary for PAC learnability under non-atomic measures.

The ECJ clarified, on the one hand, what measures EU Member States can take to effectively enforce an expulsion order against Union citizens and, on the other hand, in which cases they must grant a returning Union citizen a new right of residence. In addition, the Court confirmed its view expressed in the Petrea case, according to which national law implementing EU migration rules for third-country nationals may also apply to Union citizens, provided that their situation is comparable.

description: We investigate a formulation of continuum 4d gravity in terms of a constrained topological (BF) theory, in the spirit of the Plebanski formulation, but involving only linear constraints, of the type used recently in the spin foam approach to quantum gravity. We identify both the continuum version of the linear simplicity constraints used in the quantum discrete context and a linear version of the quadratic volume constraints that are necessary to complete the reduction from the topological theory to gravity. We illustrate and discuss also the discrete counterpart of the same continuum linear constraints. Moreover, we show under which additional conditions the discrete volume constraints follow from the simplicity constraints, thus playing the role of secondary constraints. Our analysis clarifies how the discrete constructions of spin foam models are related to a continuum theory with an action principle that is equivalent to general relativity.

Is tidal heating sufficient to explain bloated exoplanets? Consistent calculations accounting for finite initial eccentricity

description: In this paper, we present the consistent evolution of short-period exoplanets coupling the tidal and gravothermal evolution of the planet. Contrarily to previous similar studies, our calculations are based on the complete tidal evolution equations of the Hut model, valid at any order in eccentricity, obliquity and spin. We demonstrate, both analytically and numerically, that, except if the system was formed with a nearly circular orbit (e<0.2), solving consistently the complete tidal equations is mandatory to derive correct tidal evolution histories. We show that calculations based on tidal models truncated at second order in eccentricity, as done in all previous studies, lead to erroneous tidal evolutions. As a consequence, tidal energy dissipation rates are severely underestimated in all these calculations and the characteristic timescales for the various orbital parameters evolutions can be wrong by up to three orders in magnitude. Based on these complete, consistent calculations, we revisit the viability of the tidal heating hypothesis to explain the anomalously large radius of transiting giant planets. We show that, even though tidal dissipation does provide a substantial contribution to the planet's heat budget and can explain some of the moderately bloated hot-Jupiters, this mechanism can not explain alone the properties of the most inflated objects, including HD 209458b. Indeed, solving the complete tidal equations shows that enhanced tidal dissipation and thus orbit circularization occur too early during the planet's evolution to provide enough extra energy at the present epoch. In that case another mechanisms, such as stellar irradiation induced surface winds dissipating in the planet's tidal bulges, or inefficient convection in the planet's interior must be invoked, together with tidal dissipation, to provide all the pieces of the abnormally large exoplanet puzzle.

description: Pulse-based Time-of-Flight (PB-ToF) cameras are an attractive alternative range imaging approach, compared to the widely commercialized Amplitude Modulated Continuous-Wave Time-of-Flight (AMCW-ToF) approach. This paper presents an in-depth evaluation of a PB-ToF camera prototype based on the Hamamatsu area sensor S11963-01CR. We evaluate different ToF-related effects, i.e., temperature drift, systematic error, depth inhomogeneity, multi-path effects, and motion artefacts. Furthermore, we evaluate the systematic error of the system in more detail, and introduce novel concepts to improve the quality of range measurements by modifying the mode of operation of the PB-ToF camera. Finally, we describe the means of measuring the gate response of the PB-ToF sensor and using this information for PB-ToF sensor simulation

description: Hospital emergency department (ED) visits by asthmatics differ based on race and season. The objectives of this study were to investigate season- and race-specific disparities for asthma risk, and to identify environmental exposure variables associated with ED visits among more than 42,000 individuals of African American (AA) and European American (EA) descent identified through electronic health records (EHRs). We examined data from 42,375 individuals (AAs = 14,491, EAs = 27,884) identified in EHRs. We considered associated demographic (race, age, gender, insurance), clinical (smoking status, ED visits, FEV1%), and environmental exposures data (mold, pollen, and pollutants). Machine learning techniques, including random forest (RF), extreme gradient boosting (XGB), and decision tree (DT) were used to build and identify race- and -season-specific predictive models for asthma ED visits. Significant differences in ED visits and FEV1% among AAs and EAs were identified. ED visits by AAs was 32.0% higher than EAs and AAs had 6.4% lower FEV1% value than EAs. XGB model was used to accurately classify asthma patients visiting ED into AAs and EAs. Pollen factor and pollution (PM2.5, PM10) were the key variables for asthma in AAs and EAs, respectively. Age and cigarette smoking increase asthma risk independent of seasons. In this study, we observed racial and season-specific disparities between AAs and EAs asthmatics for ED visit and FEV1% severity, suggesting the need to address asthma disparities through key predictors including socio-economic status, particulate matter, and mold.
Using Japanese sources for academic research : information-seeking behaviours of graduate students

description: Traditionally, library and information studies have found that people strategize their information seeking depending on their plans and situations. When it comes to locating Japanese information sources in English-speaking countries, previous studies found that barriers by geography, language, and culture influenced their strategies. However, less studied is how Japanese information sources are sought by graduate students, who have unique information-seeking behaviors compared to undergraduate students and faculty members. To fill the research gap, I investigated the intersections of Japanese-language sources, information-seeking strategies, and graduate students. I conducted semi-structured virtual interviews with eight graduate students at the University of British Columbia (UBC), five in the Department of Asian Studies and three in the Faculty of Education. The interviews were transcribed and coded using a directed content analysis approach. Participants’ self-report indicated that they strategize information seeking by interacting with information systems (e.g., a discovery tool), resources (e.g., library stacks) and people (e.g., peers and librarians) and shift different strategies. The selection of strategies and shifting were affected by their plans (e.g., search habits, information literacy, research stages) and situations (e.g., geography, culture, language, academics’ roles). Also, most participants used resources and strategies available within UBC community, such as UBC library collections and services and asking for help from supervisors, librarians, and peers. Participants also reported that time and budgetary constraints limited opportunities for travelling to Japanese library institutions. Disciplinary differences were also found. Education students, who did not have Japanese-speaking supervisors, did not rely on people at UBC, whereas Asian Studies students frequently mentioned help from their supervisors. These findings suggest that information professionals continue advocating for collection development, international interlibrary loans, digitization and open access. Partnership with faculty members would also help outreach the available library services for graduate students. Also, faculty and departments could provide travel grants for students to visit library institutions overseas, as participants’ time and budgetary constraints forced them to give up accessing physical copies that are only available at Japanese institutions. Future research is expected to explore graduate students in other disciplines and other languages, and employ different research method (e.g., research diaries).
Posture in College Students: a quantitative analysis of the relationship between body alignment and physical fitness

description: Abstract Background: This study arose from a need to prepare a physical education course for nursing students to help reduce their risk for back pain, by improving posture and fitness. It is hoped that the results of this study will advance the teaching of fitness from a body alignment perspective. The hypothesis was that posture and muscle fitness are correlated. Purpose: The aim of the study was to address the following questions: (1) what are the rates of alignment deficits among students? Are there relationships between alignment deficits? What is the relationship between body alignment and fitness – general muscle strength and mobility? Methods: 502 student participants assessed their body alignment, general muscle fitness and mobility. Data was entered via their cell phones into an excel sheet for analysis. Results: only 18 participants had neutral alignment; these students had better scores on muscle fitness tests. The study also identified relationships between alignment deficits. Analysis of population variance revealed that underweight, female and younger participants had higher rates of alignment deficits. Conclusions: 1. posture and muscle fitness are correlated; 2. underweight is a significant deterrent to posture; 3. cell phone usage is an important determinant of posture in the sagittal plane; 4. Hand dominance is an important determinant of posture in the frontal plane; 5. alignment in the frontal and transverse planes are correlated. Key words: Body Alignment, Hand Dominance, Transverse Plane, Underweight, Cell Phone Usage

Nothing (About Us) Without Us. Activism of Women-led Disability Civil Society Organisations in Post-socialist Poland
Creators: name: Szarota, Magdalena
Publisher: name: Lancaster University
Year: 2023

description: Taking a Disability Studies perspective, this thesis aims to answer the question: what is possible in women-led disability activism in post-socialist Poland? Specifically, it examines how three case study organisations – which were identified as the key sites of women-led disability activism – have conceptualized disability, ‘the personal is political’ and activism in the period between 2004 (establishment of the first Polish disabled women’s organisation) and 2018 (Concluding Observations by UN Committee on the Rights of Persons with Disabilities regarding the implementation of the CRPD by the Polish state). The study draws on a qualitative analysis of seven semi-structured interviews with key representatives of the case study organisations. It also examines the organisations’ open-access materials. The thesis makes numerous contributions to Polish and international Disability Studies. In particular, it constitutes the first academic exploration of Polish women-led civil society organisations within Disability Studies.The thesis examines how discrimination and depoliticisation based on gender and disability is influenced by political and economic discourses dominant in post-socialist Poland. The study also offers the first mapping and analysis of the post-1989 Polish academic disability discourse. Furthermore, it evidences that the case study organisations should be categorized as feminist – whether they explicitly identify as such, and regardless of what type of feminism(s) they represent. The thesis also investigates how the feminist premise ‘personal is political’ manifests in case study organisations’ activism. Moreover, it demonstrates that the organisations under analysis conceptualize disability in ways that challenge the dominant socio-legal understandings of this notion. They also offer insightful alternatives. Finally, the thesis reveals that – unlike the majority of Polish disability organisations – the case study ones position themselves in the politicized segment of the Polish civil society, rather than in its depoliticized and charity-oriented part. Overall, the study argues that the key womenled disability organisations and their leaders enrich existing debates about activism and disability, and they provide important critiques of the Polish post-socialist society and state.

description: We report the discovery of three extrasolar planets that transit their moderately bright (Vmag = 12-13) host stars. WASP-44b is a 0.89-MJup planet in a 2.42-day orbit around a G8V star. WASP-45b is a 1.03-MJup planet which passes in front of the limb of its K2V host star every 3.13 days. Weak Ca II H+K emission seen in the spectra of WASP-45 suggests the star is chromospherically active. WASP-46b is a 2.10-MJup planet in a 1.43-day orbit around a G6V star. Rotational modulation of the light curves of WASP-46 and weak Ca II H+K emission in its spectra show the star to be photospherically and chromospherically active. We imposed circular orbits in our analyses as the radial velocity data are consistent with (near-)circular orbits, as could be expected from both empirical and tidal-theory perspectives for such short-period, Jupiter-mass planets. We discuss the impact of fitting for eccentric orbits for such planets when not supported by the data. The derived planetary and stellar radii depend on the fitted eccentricity and these parameters inform intense theoretical efforts concerning tidal circularisation and heating, bulk planetary composition and the observed systematic errors in planetary and stellar radii. As such, we recommend exercising caution in fitting the orbits of short period, Jupiter-mass planets with an eccentric model when there is no evidence of non-circularity.

description: The interaction between various charmed mesons and charmed baryons are studied within the framework of the coupled channel unitary approach with the local hidden gauge formalism. Several meson-baryon dynamically generated narrow $N^*$ and $Λ^*$ resonances with hidden charm are predicted with mass above 4 GeV and width smaller than 100 MeV. The predicted new resonances definitely cannot be accommodated by quark models with three constituent quarks and can be looked for at the forthcoming PANDA/FAIR experiments.

description: We study the physics potential of a neutrino superbeam experiment with a 2540 km baseline. We assume a neutrino beam similar to the NuMI beam in medium energy configuration. We consider a 100 kton totally active scintillator detector at a 7 mr off-axis location. We find that such a configuration has outstanding hierarchy discriminating capability. In conjunction with the data from the present reactor neutrino experiments, it can determine the neutrino mass hierarchy at 3 sigma level in less than 5 years, if sin^2(2*theta13) > 0.01, running in the neutrino mode alone. As a stand alone experiment, with a 5 year neutrino run and a 5 year anti-neutrino run, it can determine non-zero theta13 at 3 sigma level if sin^2(2*theta13) > 7*10^{-3} and hierarchy at 3 sigma level if sin^2(2*theta13) > 8*10^{-3}. This data can also distinguish deltaCP = pi/2 from the CP conserving values of 0 and pi, for sin^2(2*theta13) > 0.02.
